SUMMARY

Problems to be Solved by the Present Disclosure

Nevertheless, the dirt removing system of Non-Patent Document 1 has a problem that a beating force and a beating speed are unstable and the degree of decontamination is different or the hand fatigue is caused, since dirt removing actions are performed with a hand holding the bottle body moving up and down. In addition, since the detergent in the bottle body cannot be replaced, it is not possible to use detergents depending on the type or the state of the dirt such as oil contamination or water contamination. Therefore, sometimes it is difficult to remove the dirt.

The present disclosure aims to effectively solve such problems, that is, aims to provide a dirt removing device and a dirt removing system which can prevent the hand from tiredness, and can perform a dirt removing operation always with a stable beating force and beating speed. The device further can use different kinds of detergent according to the type and state of the dirt.

Solution for Solving the Problem

In view of the above problems, the following solutions are proposed.

The dirt removing device of the present disclosure includes a cassette mechanism having a head formed with a beating surface, a liquid accommodating portion for accommodating liquid, and a water supplying passage which is started from the liquid accommodating portion and penetrates into the entire head; and a device body having a vibration unit. The cassette mechanism is detachably received in the vibration unit, and the vibration unit, when being powered, causes the cassette mechanism to vibrate in a direction substantially orthogonal with the beating surface of the head. The liquid is supplied from the liquid accommodating portion to the beating surface of the head through the water supplying passage, along with the vibration of the cassette mechanism caused by the vibration unit

Preferably, the head is detachable from the cassette mechanism, and the liquid accommodating portion is composed of an accommodating portion body having a liquid accommodating space therein and a cover member for opening and closing the liquid accommodating space.

Preferably, the liquid accommodating portion is transparent or translucent.

Preferably, the water supplying passage is started from the liquid accommodating portion, penetrates into the entire head and extends to the beating surface, and expands toward an open end opening to the beating surface.

Preferably, the device body further has a non-flexible waterproof cover surrounding a side surface of the head; the vibration unit has an elastic member capable of extending and contracting in a direction substantially orthogonal with the beating surface, and the head is protruded by an elastic force of the elastic member; and an action end at a side of the head is set at a position slightly protruding from a protruding end of the waterproof cover.

In addition, the dirt removing unit of the present disclosure includes the above dirt removing device; and a heating device. The heating device includes at least a heater that generates heat by power supply and a heating plate that forms a knocked surface, a force is exerted to which by the head constituting the dirt removing device, and conveys a heat generated by the heater.

Effect of the disclosure

According to the above described disclosure, the vibration unit causes, by means of supplying power, the cassette mechanism to vibrate in the direction substantially orthogonal with the beating face of the head, the head can automatically perform an action of beating the dirt and removing objects. As a result, the beating force and the beating speed are homogeneous and the hands are required to move quickly, the hands will not be tired even if the dirt removing operation is performed for a long time. In addition, since the cassette mechanism can be attached and detached from the device body, it is possible to install, on the device body, a cassette mechanism accommodating a liquid corresponding to the state of the dirt, and to change the type of the liquid according to the state of the dirt portion, by means of, for example, preparing in advance a plurality of cassette mechanisms each accommodating a different kind of liquid, respectively, in the liquid accommodating portion, thereby improving the effect of removing dirt.

In particular, according to the present disclosure, the head potion is detachable from the cassette mechanism, and the liquid accommodating portion is composed of an accommodating portion body and a cover member. The liquid can be supplied to the liquid accommodating space or the liquid in the liquid accommodating portion can be easily replaced with other kind of liquid, by means of removing the cover member form the accommodating portion body, so that the dirt removing device can be repeatedly used multiple times. In this case, since the liquid supplying, replacement and the like can be performed in a state in which the liquid accommodating portion is removed from the device body, the device body will not be wetted by the liquid when supplying liquid and the device body is not required to be subjected to a waterproof treatment. In addition, the inside of the liquid accommodating portion can be cleaned by disassembling the liquid accommodating portion into the accommodating portion body and the cover member, thereby easily removing the incrustation, the calcium component, and the like. Further, the dirt removing effect can be further improved, since the most suitable head and liquid can be selected to use according to the state of the dirt portion.

Further, according to the present disclosure in which the liquid accommodating portion is transparent or translucent, the cassette mechanism can be temporarily removed so as to confirm the remaining amount of the liquid in the liquid accommodating portion during the process of the dirt removing operation, thereby improving the convenience.

In particular, according to the present disclosure in which an open end of the water supplying passage is expanded, even if the solid soil constituting the dirt portion is physically decomposed due to the impact from the head, the decomposed solid soil does not dissolve into the liquid and penetrates into the water supplying passage, the water supplying passage is difficulty to be blocked by the solid soil, since the open end expands. In addition, even if the water supplying passage is blocked and full of solid soil, it is easy to remove the solid soil.

In addition, according to the present disclosure, the waterproof cover can block the liquid from spattering so as to prevent large-scale diffusion of the liquid, and always keep a distance from the device body to the clothe is constant in the dirt removing operation, so that a force (beating force) applied by the head to a dirt removing object is appropriate and uniform. In addition, since the head presses against the dirt removing object due to the elasticity of an elastic member when the elastic member is protruding, it is possible to automatically simulate the action of beating (pressing) the dirt portion by hands.

In another aspect, according to the present disclosure having the above described dirt removing device and a heating device, since the dirt portion of the dirt removing object can be continuously heated by the heat from the heater and the dirt removing operation can be performed, the dirt is more likely soluble in liquid, thereby further improving the dirt removing effect.

Specifically, FIG. 1(A) is a perspective view showing the dirt removing device 100 according to the present embodiment. FIG. 1(B) is a side view showing the dirt removing device 100. FIG. 1(C) is a top view showing the dirt removing device 100. In addition, FIG. 2(A) is a longitudinal section view of the dirt removing device 100 along a section line II-II in FIG. 1(C). FIG. 2(B) is a perspective view showing a part of the dirt removing device 100, that is, a part in the vicinity of an engaging claw 45b2. FIG. 2(C) is an enlarged longitudinal section view showing a part of a liquid accommodating portion 12 and a head 11 shown in FIG. 2(A). FIG. 2(D) is a bottom view of the head 11.

As shown in FIG. 2(A), the dirt removing device 100 includes: a device body 3, a cassette mechanism 1, a cover member 70 and a waterproof cover 50.

The cassette mechanism 1 is detachably received in the device body 3. The device body 3 includes a vibration unit 31, a battery 32 and a housing body 33 having a dimidiate structure in which these components are mounted.

The vibration unit 31 is a member that causes, while being powered, the cassette mechanism 1, which protrudes from the housing body 33 through an opening 33a, to vibrate in a direction substantially orthogonal with a beating face 21a of the head 11. Hereinafter, the direction substantially orthogonal with the beating surface 21a is referred to as a vibration direction. In addition, in the vibration direction, a direction in which the head 11 protrudes outward the device is referred to as a protruding direction Y1, and the opposite direction is referred to as a return direction Y2. Such a vibration unit 31 has a motor 41, first to third gears 42˜44, a cylinder body 45, and a coil spring 46.

The motor 41 has a driving gear 41a powered by a power supplying portion (namely the battery 32) so as to rotate.

A rotational force of the motor 41 is transmitted through the first to the third gear 42˜44. The first gear 42 includes a large diameter portion 42a which is engaged with the driving gear 41a of the motor 41 and is rotatable about a shaft 42c, and a small diameter portion 42b formed integrally with the large diameter portion 42a and coaxially arranged with the large diameter portion 42a. The second gear 43 is disposed between the first gear 42 and the third gear 44. The second gear 43 has a large diameter portion 43a which is engaged with the small diameter portion 42b of the first gear 42 and is rotatable about a shaft 43c, and a small diameter portion 43b, which is formed integrally with and coaxially arranged with the large diameter portion 43a and is engaged with the third gear 44. The third gear 44 includes a large diameter portion 44a which is engaged with the small diameter portion 43b of the second gear 43 and is rotatable about a shaft 44c, and a small diameter portion 44b. The small diameter portion 44b is formed integrally with and coaxially arranged with the large diameter portion 44a, and includes two engaging projections 44b1 protruding from an end face of the small diameter portion 44b in a circumferential direction at equal intervals. In addition, the number of the engaging projections 44b1 is not limited to two, but may be one or three or more.

The cylinder body 45 is a member that supports the cassette mechanism 1 in a manner that the beating surface 21a is located at a top end of the cylinder body 45, and is capable of moving in the vibration direction. The cylinder body 45 has a coil spring receiving portion 45a and a cassette mechanism inserted portion 45b.

The coil spring receiving portion 45a is a cylinder member having a bottom surface, in which the coil spring 46 served as an elastic member is received in a manner of being stretchable in the vibration direction.

The cassette mechanism inserted portion 45b is a substantially cylindrical member extending from a lower end of the coil spring receiving portion 45a to the vicinity of the opening 33a of the housing body 33. A cylinder opening 45b′ shown in FIG. 2 (B) is formed in a side surface of the cassette mechanism inserted portion 45b. The side surface of the cassette mechanism inserted portion 45b is further formed with an engaged claw 45b1 as shown in FIG. 2(A) and an engaging claw 45b2. The engaged claw 45b1 is capable of being engaged with the engaging projection 44b1 formed at the small diameter portion 44b of the third gear 44. The engaging claw 45b2 is capable of being engaged with the cassette mechanism 1. As shown in FIG. 2(B), the engaging claw 45b2 extends from an edge of the cylinder opening 45b′ toward the protruding direction Y1, and a top end 45b3 protrudes to a center axis of the cassette mechanism inserted portion 45b and has a substantially triangular longitudinal section. In addition, the engaging claw 45b2 is configured to be elastically deformed toward the outside of the cassette mechanism inserted portion 45b with a base end 45b4 as a starting point, along with the pressing of the cassette mechanism 1. Such engaging claws 45b2 are provided at two positions opposed to each other.

One end of the coil spring 46 is supported by a base end of a fixing portion 33b extending in a convex shape from the housing body 33 in the protruding direction Y1, and the other end is received by the coil spring receiving portion 45a.

As shown in FIG. 2(A), in the case that the engaging projection 44b1 of the third gear 44 is not engaged with the engaged claw 45b1, such cylinder body 45 is pushed out in the protruding direction Y1 together with the cassette mechanism 1 because an elastic force in the protruding direction Y1 is exerted on the bottom surface 45a1 of the coil spring receiving portion 45a by the coil spring 46.

On the other hand, in the case that the engaging projection 44b1 of the third gear 44 is engaged with the engaged claw 45b1 (referring to FIG. 4(B)), along with the rotation of the third gear 44, the cylinder body 45 exerts a compression force on the coil spring 46 via the bottom surface 45a1 and moves in the return direction Y2 together with the cassette mechanism 1. Then, when the engaging projection 44b1 is disengaged from the engaged claw 45b1, the cylinder body 45 and the cassette mechanism 1 move in the protruding direction Y1 again by means of the elastic force of the compressed coil spring 46.

The cassette mechanism 1 and the head 11 are enabled to vibrate (an amplitude vibration movement) by repeating such operations. In the present embodiment, the third gear 44 has two engaging projections 44b1 as described above, and the head 11 is caused to shuttle twice through one rotation of the third gear 44.

The battery 32 shown in FIG. 2 (A) is a dry battery in the present embodiment, and is received in the device body 3 via an opening and closing cover 34 formed at a part of the housing body 33. The opening and closing cover 34 is configured to be rotatable toward the outside of the housing body 33 via a pin 34a.

The cassette mechanism 1 vibrated by the vibration unit 31 has the head 11, the liquid accommodating portion 12, and a water supplying passage 13.

The head 11 has a beating portion 21 and a head insertion portion 22. The beating portion 21 is a member formed with the beating surface 21a, and has a substantially semicircular longitudinal section, more specifically approximately circular longitudinal section). A plurality of projections 21a1 protrude from the beating surface 21a. Each of the projections 21a1 is hemispherical, and is regularly arranged in the beating surface 21a as shown in FIG. 2 (D).

The head insertion portion 22, as shown in FIG. 2 (C), is a member extending from the beating portion 21 and pluggably inserting into an inserted portion 25 that will be described below. A side surface of the head insertion portion 22 is provided with a plurality of annular protrusions 22a which are formed in the vibrating direction and spaced apart from each other. When inserting into the inserted portion 25, the protrusions 22a press against an inner surface of the inserted portion 25. Therefore, the head 11 can be stably fixed with a constant degree even if the head insertion portion 22 has been repeatedly loaded or unloaded for lots of times.

In addition, in the present embodiment, the head 11 is made of resins such as nylon, but the material of the head 11 is not limited to the resins, it may be metals such as stainless used steel (SUS), etc.

The liquid accommodating portion 12 shown in FIG. 2 (a) has a liquid storage portion 24 and the inserted portion 25. The liquid storage portion 24 is a transparent or translucent hollow member capable of accommodating the liquid, and is configured to be capable of being decomposed as will be described later. An engaging recess 12a engageable with the engaging claw 45b2 is provided on a side surface of the liquid storage portion 24. The inserted portion 25 extends from the liquid storage portion 24, and the head insertion portion 22 of the head 11 is pluggably inserted into the inserted portion 25 by lightly pressing. In addition, the head insertion portion 22 is not limited to the structure in which the head insertion portion 22 is inserted into the inserted portion 25 by pressing. The head insertion portion 22 may be inserted into the inserted portion 25 by being fixed by a screw.

The liquid herein may be water, a detergent mixture of water and detergent mixed with a certain ratio, a common solvent such as ethanol or gasoline, or a special detergent for removing dirt, and the like. In the present embodiment, the liquid accommodated in the liquid storage portion 24 can only be water. As a result, a rinsing effect can be exerted in addition to the dirt removal effect, as will be described later.

The water supplying passage 13 is formed from the liquid accommodating portion 12 and throughout the head 11, and supplies the liquid in the liquid accommodating portion 12 to the beating surface 21a of the head 11. As shown in FIG. 2(C), the water supplying passage 13 includes a head water supplying hole 27 and a cylinder body water supplying hole 28. The head water supplying hole 27 extends through the head 11 to the beating surface 21a, and is composed of a water storage portion 27a, an expansion portion 27b, and a small diameter portion 27c.

The water storage portion 27a is opposed to the cylinder body water supplying hole 28, opens at a base end 11a of the head 11. The water storage portion 27a penetrates the head insertion portion 22, and the longitudinal section thereof is substantially a rectangle. The expansion portion 27b, a longitudinal section of which is frustum-shaped, and has an open end 11b which expands and opens toward the center of the beating surface 21a. The small diameter portion 27c is configured to connect the water storage portion 27a and the expansion portion 27b. A profile of a flow path of the small diameter portion 27c is smaller than that of the water storage portion 27a and that of the expansion portion 27b.

The cylinder body water supplying hole 28 is formed from the liquid storage portion 24 through the inserted portion 25, and opens in a tapered shape toward the base end 11a of the head 11. In addition, the longitudinal section of the cylinder body water supplying hole 28 is not limited to the tapered shape, and may be arranged to have a same diameter from the start to the end. This is also true in other embodiments described later.

The liquid in the liquid storage portion 24 drips from the cylinder body supplying hole 28 to the head 11, and is supplied to the beating surface 21a through the head water supplying hole 27.

When the cassette mechanism 1 is caused to vibrate through the vibrating of the vibration unit 31, through the water supplying passage 13 formed in such head 11, the liquid is discharged to the expansion portion 27b from the small diameter portion 27c little by little (such as 1˜1.5 cc/min) with a stable flow rate, so as to supply the liquid to the beating face 21a of the head 11. On the other hand, when the cassette mechanism 1 does not vibrate, the liquid is prevented from dripping by a surface tension in the small diameter portion 27c and the cylinder body water supplying hole 28 (particularly the small diameter portion 27c).

In this way, the cross-section of the flow path of the water supplying passage 13 is designed to discharge a small amount of liquid through the vibration of the head 11, thus less liquid is used to complete the washing compared with other washing methods such as spray washing, brushing and the like. Therefore, the liquid is hard to spatter to locations where the liquid is not needed. Further, the water supplying passage 13 is disposed only at a limited portion relative to the whole dirt removing device 100. Therefore, the clogging of the water supplying passage 13 caused by the incrustation and the coagulation of the calcium component is hard to happen, compared with a structure having a water supplying passage (not shown) longer than the water supplying passage 13 so as to extend throughout the entire dirt removing device 100. As a result, it is not necessary to carry out a complicated decomposition to clean of the dirt removing device 100.

In addition, a length β (referring to FIG. 2 (A)) of the dirt removing device 100 from the beating face 21a of the head 11 when protruding to the opening 33a of the housing body 33 is set to be a length that the dirt portion is visible to obliquely upper side without being shielded by the device body 3 in a dirt removing operation described later. In addition, the waterproof cover 50 described later is set to have a size corresponding to the length β. Further, the cassette mechanism 1 is mounted to be eccentric with respect to the cylindrical housing body 33, and the dirt removing operation is performed by bringing the side surface of the housing body 33 closest to the cassette mechanism 1 closer to the eye, so that it is easier to confirm the dirt portion.

The cover member 70 is a member that can be attached and detached from an end of the housing body 33, which is attached to the device body 3 when the dirt removing device 100 is carried, and is removed from the device body 3 when performing the dirt removing operation described later as shown in FIG. 3(A). FIG. 3(A) is a perspective view showing the dirt removing device 100 with the cover member 70 being removed. With such a cover member 70, the dirt removing device 100 is effectively prevented from leaking water from the device while being carried, impact on the cassette mechanism 1 and the like.

In addition, FIG. 3(B) is a perspective view showing the dirt removing device 100 with the waterproof cover 50 being removed. Also as shown in FIG. 3(B), the waterproof cover 50 is configured to be detachable from the end of the housing body 33. In addition, the related structure of the waterproof cover 50 will be described later in detail.

Such dirt removing device 100 is a handheld device that can locally wash a cloth C as the dirt removing object shown in FIG. 4. FIG. 4 is a longitudinal section view illustrating a use state of the dirt removing device. When the dirt removing operation is performed, an absorbing pad P served as a pad abuts the bottom of the dirt portion Sp of the cloth C, and coats a detergent for removing dirt to the dirt portion Sp of the cloth C directly. Further, a protruding end 51 of the waterproof cover 50 presses the cloth C at a position, opposed to the dirt portion Sp, of the beating face 21a of the head 11. Further, the dirt removing device 100 is used with a region around an annular anti-slip portion 33d of the housing body 33 being held. In addition, the detergent may not be used in the present embodiment.

When a power switch Sw provided on the outside of the housing body 33 is operated in this state, the motor 41 is powered by the battery 32 to rotate, and the rotation is transmitted to the third gear 44 through the first gear 42 and the second gear 43 after being decelerated. As shown in FIG. 4(B), when the engaging projection 44b1 is engaged with the engaged claw 45b1, the cylinder body 45 and the cassette mechanism 1 are lifted together by a specified size 6 (about 5 mm in the present embodiment). Then, when the engaging projection 44b1 is disengaged from the engaged claw 45b1, the cylinder body 45 and the cassette mechanism 1 are ejected by the elastic force of the coil spring 46, as shown in FIG. 4(A), the head 11 beats the dirt portion Sp.

In addition, along with the vibration of the cassette mechanism 1, the liquid and air in the liquid storage portion 24 are whisked, therefore, a negative pressure will not generated in the liquid storage portion 24. The liquid gradually drops through the water supplying passage 13 immediately after the vibration is started and is supplied to the dirt portion Sp via the beating surface 21a.

When the device body 3 moves along the cloth C and repeats such operations, the liquid (only water is used in the present embodiment) supplied to the dirt portion Sp together with the detergent coated on the dirt portion Sp dissolve the feculence constituting the dirt portion Sp, and the feculence is knocked out from the cloth C and absorbed by the absorbing pad P. That is, the dirt removing device 100 is device that removes the dirt by transferring the feculence of the cloth C together with the liquid and the detergent to the absorbing pad P.

In addition, in the present embodiment, after the dirt being removed, it is also effective to proceed with the operation described above for a certain time, thereby transferring the detergent remained in the dirt portion Sp to the absorbing pad P, and a rinsing effect is achieved.

In addition, the absorbing pad P is not particularly limited, and a variety of articles can be used as the absorbing pad P as long as the liquid can be absorbed at a high speed, for example, a product generated by folding a kitchen paper towel.

Further, as long as an operation of changing the position where the head 11 abuts against the absorbing pad P is periodically performed during the dirt removing operation, the dropped liquid will be stably absorbed by the absorbing pad P. Therefore, a high efficiency dirt removing can be maintained.

Since the vibration unit 31, while being powered, causes the cassette mechanism 1 to vibrate in the direction substantially orthogonal with the beating surface 21a, the head 11 can automatically perform the action of beating the cloth C. Therefore, such dirt removing device 100 has the following excellent effects: having uniform beating force and beating speed, and it is not required to move the hands quickly, thus the user will not fatigue even if the dirt removing operation is performed for a long time.

In addition, although the dirt may be for example a solid feculence in block which is adhered to the cloth C and difficult to be dissolved in the liquid, the dirt removing device 100 can physically decompose the solid feculence by the impact from the head 11 so that the solid feculence is easily dissolved in the liquid. In addition, for example, by appropriately designing the cross-section of the flow path of the water supplying passage 13, an appropriate amount of liquid is continuously supplied to the cloth C along with the vibration, and the dirt removing effect is improved. Further, since the dirt removing device 100 is of a structure in which the liquid drops by vibration, the structure is simplified and the size is reduced compared with a device, for example, in which a liquid pump is employed to supply the liquid.

As a result, the dirt removing device 100 of the present embodiment is a small and portable device. Therefore, in the case that food residue, cosmetic or the like is adhered to the cloth when going out, it is enable to make the dirt not obvious by means of local washing. In addition, the dirt removing device 100 can locally and properly wash goods that are difficult to overall wash, such as curtains, carpet, etc. Further, the dirt removing device 100 can pre-wash the feculence at a collar, cuffs, etc. of the cloth C in an early stage of washing performed by a washing machine.

Further, as described above, the water supplying passage 13 extends from the liquid accommodating portion 12 to the beating face 21a and passes through the head 11, and expands to the open end 11b (as shown in FIG. 2(C)) opening to the beating face 21a. As a result, even if the solid feculence constituting the dirt portion Sp, after being physically decomposed by the impact from head 11, is not dissolved in the liquid and gets into the water supplying passage 13, the water supplying passage 13 is hard to be blocked by the solid feculence, since the open end 11b expands. In addition, even if the water supplying passage 13 is blocked full of solid feculence, it is easy to remove solid feculence.

As shown in FIG. 4, the waterproof cover 50 is a transparent non-flexible member made of propylene and has a substantially conical shape (that is, a shape in which the circumference of the protruding end 51 is larger than the circumference of a base end 51′). The waterproof cover 50 is detachably mounted around the opening 33a of the housing body 33 at a position on a side surface encircling the head 11 via a rib 33a1. The head 11 protruding towards the protruding direction Y1 by the vibration unit 31 adjusts the course thereof, so that an action end of one side is arranged at a position slightly protruding from the protruding end 51 of the waterproof cover 50. Specifically, a distance t (referring to FIG. 4 (A)) in the vibration direction from the beating surface 21a of the head at the protruding position to the protruding end 51 of the waterproof cover 50 is set to be a prescribed distance (about 1 to 2 mm in the present embodiment).

By providing such waterproof cover 50, during the dirt removing operation, the waterproof cover 50 shields the liquid scattered by the vibration of the head 11, so as to prevent the liquid from diffusing in a wide range. Therefore, the area where the cloth C is soaked is reduced, thus the cloth C can be wore immediately after the dirt removing operations. In addition, during the dirt removing operation, a distance between the device body 3 and the cloth C can be kept constant, so that the external force (beating force) exerted on the cloth C by the head 11 is appropriate and uniform. In addition, the action end at a side of the head 11 is arranged at a position slightly protruding from the protruding end of the waterproof cover 50, and the head 11 presses against the cloth C due to the elasticity of the elastic member when protruding, thus it is possible to automatically simulate the action of beating (pressing) the dirt portion Sp by hands. Further, since the waterproof cover 50 is transparent, it is possible to confirm the removing state of the dirt portion via the waterproof cover 50 during the dirt removing process.

In addition, the shape of the waterproof cover 50 is not limited to a substantially conical shape, but may be, for example, a cylindrical shape.

In addition, as described above, the cassette mechanism 1 is detachable to the device body 3 via the engaging claw 45b2 (referring to FIG. 2 (B)) (bottle cassette type).

Specifically, as shown in FIG. 5, after the waterproof cover 50 is removed from the device body 3, the inserted portion 25 or its periphery is pulled out by grasping and pulling with by a certain force. The pulling force is transmitted to a top end 45b3 of the engaging claw 45b2 from the engaging recessed portion 12a of the liquid storage portion 24, therefore, the engaging claw 45b2 is temporarily elastically deformed toward the outside of the cassette mechanism inserted portion 45b with the base end 45b4 as a starting point, and the cassette mechanism 1 is separated from the device body 3. In addition, FIG. 5 is a longitudinal section view showing the same dirt removing device with the cassette mechanism 1 being removed.

On the other hand, by an opposite action as described above, specifically, by inserting the cassette mechanism 1 into the cassette mechanism inserted portion 45b with a certain force, the insertion force is transmitted to the top end 45b3 of the engaging claw 45b2 from an end face 24′ of the liquid storage portion 24, and the engaging claw 45b2 is elastically deformed toward the outside of the cassette mechanism inserted portion 45b with the base end 45b4 as a starting point. When the cassette mechanism 1 is further inserted in such state, the engaging claw 45b2 is elastically recovered at a position opposed to the engaging recess 12a of the liquid storage portion 24, and the engaging recess 12a is engaged with the engaging claw 45b2 to prevent from detaching, so that the cassette mechanism 1 is mounted on the device body 3.

Since the cassette mechanism 1 can be attached and detached in such a way, a cassette mechanism 1 containing liquid corresponding to the state of the dirt portion Sp can be mounted on the device body 3 by preparing, for example, a plurality of cassette mechanisms 1 in advance, each having a liquid accommodating portion 12 containing a different kind of liquid respectively. Therefore, the type of the liquid can be replaced according to the state of the dirt portion Sp, thereby improving the dirt removing effect.

FIGS. 6 (A) and 6 (B) are perspective views showing the cassette mechanism 1 when being detachd from the device body 3. As shown in FIG. 6 (A), the liquid storage portion 24 of the cassette mechanism 1 is disassembly composed of an accommodating portion body 24a and a cover member 24b. The accommodating portion body 24a is a substantially cylindrical member having a liquid accommodating space S formed therein and has a bottom. The accommodating portion body 24a is arranged in a manner that a part of the accommodating portion body 24a in an axial direction is reduced in a radial direction, thereby forming the engaging recess portion 12a. The cover member 24b is a member provided at an opening side of the accommodating portion body 24a, and is fixed and mounted on the accommodating portion body 24a by means of a screw. The cover member 24b is configured to open and close the liquid accommodating space S. In addition, the head 11 is configured to be detachable to the inserted portion 25, that is, the head 11 can be attached and detached to the cassette mechanism 1.

With such a structure which can be divided into three parts, the cover member 24b can be detached from the accommodating portion body 24a so as to supply the liquid to the liquid accommodating space S, or replace the liquid in the liquid accommodating portion 12 with another kind of liquid (For example, ordinary solvents such as ethanol and gasoline) easily. Therefore, the dirt removing device 100 can be used repeatedly. At this time, since the liquid supplying or replacement can be performed when the liquid accommodating portion 12 is detached from the device body 3, the device body 3 will not be wetted by the liquid when the liquid accommodating portion 12 is supplied. Therefore, it is not necessary to perform waterproofing treatment on the device body 3. In addition, the liquid storage portion 24 can be disassembled into the accommodating portion body 24a and the cover member 24b so as to clean the inside of the liquid accommodating portion 12, and the incrustation or calcium component can be easily removed. Further, the head 11 having the best shape and the best liquid can be selected for use according to the state of the dirt portion Sp and the like, and the head 11 itself can be replaced with a new one, thereby improving the dirt removing effect.

Further, since such liquid accommodating portion 12 is transparent or translucent as described above, the cassette mechanism 1 can be temporarily detached during the dirt removing operation so as to confirm the remaining amount of the liquid in the liquid accommodating portion 12, thereby improving the convenience.

FIG. 6 (C) is a longitudinal section view showing a modified embodiment of embodiment I. Specifically, FIG. 6 (C) is a longitudinal section view showing a part of the cassette mechanism 10 constituting the modified embodiment (that is, the dirt removing device 110), that is, a part of a liquid accommodating portion 212, and a head 5. The dirt removing device 110 is configured in a manner that the liquid flows to the periphery of the solid head 5 and reaches the beating surface 21a rather than flowing inside the head 5 and reaching the beating surface 21a. That is, the structure of a water supplying passage 6 is different from that of the first embodiment. The modified embodiment is the same as the first embodiment except for the structure described later, and the description of the same structure will be omitted.

In the dirt removing device 110, the water supplying passage 6 is composed of a cylinder water supplying hole 28, a water supplying groove 6a, and an inserted portion 25.

The water supplying groove 6a is formed on the outer circumference of a head insertion portion 52 of the head 5, and is intermittently formed in a manner of slits extending in the axial direction by a prescribed depth (about 0.1˜0.3 mm in the present embodiment). The liquid in the liquid storage portion 24 (as shown in FIG. 5) is supplied to a base end 5a of the head 5 via the cylinder water supplying hole 28. When the vibration of the vibration unit 31 (as shown in FIG. 5) causes the head 5 to vibrates, the liquid is slightly discharged to the beating portion 21 little by little (for example, 1˜1.5 cc/min) from the gap (that is, a discharging port 6b) between the inserted portion 25 and the cylinder body insertion portion 52 to the beating surface 21a and reaches the beating surface 21a.

On the other hand, when the head 5 does not vibrate, the liquid remains between the inserted portion 25 and the water supplying groove 6a and is prevented from dripping due to a surface tension.

In this way, the discharging port 6b for the liquid is opened at the periphery of the head 5 rather than the beating surface 21a of the head, thus the liquid is supplied to the periphery of the head 5. Therefore, the water supplying passage 6 will not be blocked even if the solid feculence constituting the dirt portion Sp is attached to the beating surface 21a, thereby stably maintaining the dirt removing effect. In addition, the water supplying groove 6a may be formed on the inserted portion 25 rather than in the head insertion portion 52.

Embodiment II

FIG. 7 shows a part of a cassette mechanism 20 that constitutes embodiment II (that is, a dirt removing device 120) of the present disclosure. Specifically, FIG. 7 is a perspective view showing a part of a liquid accommodating portion 7 and a head 8. FIG. 7(A) shows the cassette mechanism 20 before the head 8 is inserted into the liquid accommodating portion 7. FIG. 7(B) shows the cassette mechanism 20 after the head 8 is inserted into the liquid accommodating portion 7. The dirt removing device 120 of the present embodiment is different from embodiment I in that the dirt removing device 120 has a liquid amount adjustment portion 9 for adjusting the drop amount of the liquid. Hereinafter, embodiment II is the same as embodiment I except for the structure described later, and the description of the same structure will be omitted. In addition, for easy description, although it is not shown in the drawings that the liquid storage portion 71 of the liquid accommodating portion 7 has a decomposable structure, the liquid storage portion 71 is of a structure that can be disassembled into an accommodating portion body having a liquid accommodating space therein and a cover member for opening and closing the liquid accommodating space.

The liquid amount adjustment portion 9 shown in FIG. 7 is composed of the liquid accommodating portion 7 and the head 8. The liquid storage portion 71 of the liquid accommodating portion 7 adjoins an inserted portion 72 via a separation portion 73, and there is first to third supplying regions 73a˜73c formed at equal intervals in an edge portion of the separation portion 73. Each of these supplying regions 73a˜73c is provided with a different number of supplying holes 73x penetrating through the separation portion 73. In the present embodiment, the first supplying region 73a is provided with one supplying hole 73x, the second supplying region 73b is provided with three supplying holes 73x, and the third supplying region 73c is provided with five supplying holes 73x. In addition, the number of the supplying holes 73x is not limited thereto. In addition, the head 8 has a notch 8b at an end of the head insertion portion 8a, and a plurality of water supplying grooves 8c extending from the notch 8b to the beating portion 21 are provided in a side portion of the head insertion portion 8a.

FIG. 8 is a schematic diagram showing the head 8 and the supplying holes 73x shown in FIG. 7 (B). Slashes are added at the notch 8b in FIG. 8. As shown in FIG. 8, the notch 8b is formed on the head insertion portion 8a in a range corresponding to one supplying region 73a (73b, 73c). The liquid in the liquid storage portion 71 shown in FIG. 7 flows into the notch 8b from the supplying holes 73x formed in any one of the supplying regions 73a (73b, 73c) in alignment with the notch 8b, and drops to the periphery beating portion 21 through the discharging port 6b of the water supplying groove 8c. Therefore, the drop amount of the liquid varies depending on the supplying region 73a (73b, 73c) in alignment with the notch 8b, and the drop amount of the liquid increases in the following order: a state shown in FIG. 8(A) where the notch 8b is in alignment with the first supplying region 73a, a state shown in FIG. 8(B) where the notch 8b is in alignment with the second supplying region 73b and a state shown in FIG. 8(C) where the notch 8b is in alignment with the third supplying region 73c.

As described above, the dirt removing device 120 of the present embodiment is a device, in which the water supplying passage 6′ is composed of the supplying holes 73x, the notch 8b, the water supplying groove 8c, and the inserted portion 72; and the liquid drops from the gap (that is, the discharging port 6b) between the water supplying groove 8c and the inserted portion 72 by means of the vibration of the vibration unit 31 (as shown in FIG. 5). The dirt removing device 120 has the liquid amount adjustment portion 9 as shown in FIG. 7 capable of adjusting the dropping amount of the liquid.

The liquid drops too much and sometimes a circular stain is generated when only the depth of the water supplying groove 6a is designed, but the liquid will drop to the cloth C in an exact amount by means of using the liquid amount adjustment portion 9. Therefore, the dirt removing device 120 is capable of preventing the degradation of the dirt removing effect caused by insufficient supplying of the liquid, and preventing the generation of the circular stain caused by supplying a large amount of liquid to the dirt portion Sp once.

In addition, the liquid amount adjustment portion 9 is not limited to the above-described configuration as long as it can adjust the dropping amount of the liquid. In addition, the structure of the liquid amount adjustment portion 9 may be applied to the dirt removing devices 100 and 110 of other embodiments. In addition, although the water supplying groove 8c is formed in the head insertion portion 8a in the present embodiment, it may be formed on the inserted portion 72.

Embodiment III

FIG. 9 is a longitudinal section view showing a dirt removing unit 130 according to embodiment III of the present invention. FIG. 10 is an exploded view showing a heating device 101 constituting the dirt removing unit 130 shown in FIG. 9. The dirt removing unit 130 of the present embodiment shown in FIG. 9 is composed of the dirt removing device 100 of embodiment I and the heating device 101.

As shown in FIG. 10, the heating device 101 includes a member 103 for arranging an absorbing pad (a cover for arranging an absorbing pad), a device body cover 105, a decorative panel 107, a heating plate 109, a first heat insulating material 111, a heater 113, a second heat insulating material 115 and a heating device body 117.

The member 103 for arranging an absorbing pad and the device body cover 105 are circular members in which opening portions 103a and 105a are formed at the centers, respectively. The member 103 for arranging an absorbing pad rotates in a state in which an absorbing pad P is sandwiched between a surface 103b of the member 103 and a surface 105b of the device body cover 105, and the screw portion of the surface 105b and the crew portion of the surface 103c are engaged with each other and mounted on the device body cover 105. The decorative panel 107 has stepped differences between a central portion 107a and an end portion 107b. A protuberant surface 107ab of the central portion 107a is exposed via the opening portion 105a and is substantially parallel to the surface 105b of the device body cover 105, the end portion 107b is sandwiched between another surface 105d of the device body cover 105 and the heating device body 117, when being mounted inside the heating device 101. The decorative panel 107 is made of, for example, stainless steel. Through holes 107c and 105e penetrating a safety switch 117d which will be described later are formed on the end portion 107b of the decorative panel 107 and the device body cover 105, respectively.

The heating plate 109 is configured to be embedded in the central portion of the decorative panel 107, and a beaten surface 109a on which a force is exerted by the head 11 of the dirt removing device 100, is opposed to the decorative panel 107. The heating plate 109 is made of, for example, aluminum having high thermal conductivity. The thickness of the heating plate 109 is set to about 1 to 2 mm. The heat from the heater 113 can be quickly and uniformly transmitted to the absorbing pad P and the deformation of the absorbing pad P during dirt removing operation caused by the force exerted by the head 11 can be suppressed, because both the strength and the high thermal conductivity are taken into account of, thereby maintaining a high dirt removing efficiency.

The first heat insulating material 111 is a heat insulating material for temperature adjustment disposed on the back side of the heating plate 109, and is made of, for example, silicone rubber. The second heat insulating material 115 is a member disposed on the heating device body 117 and configured to insulate the heat of the heater 113, and is made of, for example, glass wool. The heater 113 disposed between these heat insulating materials, for example, may be a ceramic heater. In addition, a coating treatment may be applied to the heating plate 109 for a beautiful appearance, so that a structure without the decorative panel 107 can be used.

The heating device body 117 includes a power line 117a, a main switch 117b for switching a power state of the heater 113, a temperature regulator 117c for adjusting the power state of the heater 113 according to the temperature of the heater 113, and the safety switch 117d. When the upper limit temperature (e.g., 70° C.) is reached, the temperature regulator 117c stops supplying power to the heater 113 so as to cool the heater 113. When the lower limit temperature (e.g., 60° C.) is reached, the heater 113 is powered again. The safety switch 117d is a member protruding from the surface 105b of the device body cover 105 via the through holes 107c and 105e, and is configured to supply power to the heater 113 when being pressed by the absorbing pad P mounted at a predetermined position and stop supplying power to the heater 113 when not being pressed. That is, the heating device 101 can be used by disposing the absorbing pad P at the predetermined position of the device body cover 105 and closing the member 103 for arranging the absorbing pad.

According to the heating device 101 of such structure, the heater 113 generates heat after operating the main switch 117b, and the heat is transferred to the heating plate 109 so as to increase the temperature of the absorbing pad P. Therefore, when the cloth C is placed on the heating device 101, an action of applying a beating force to the beaten surface 109a by the head 11 of the dirt removing device 100 can be performed in a state in which the heated absorbing pad P is opposed to the dirt portion Sp. The dirt removing unit 130 of the present embodiment continuously heats the dirt portion Sp to about 50° C., so that the dirt removing operation is performed in a state in which the dirt is more dissoluble to the liquid, thereby further improving the dirt removing effect. In addition, it is unnecessary to use a strong bleaching agent for dirt removing, so that discoloration of clothes C can be prevented.

In addition, according to the present embodiment, the heating device 101 is used in combination with the dirt removing device 100 of the embodiment I, however, the heating device 101 may be used in combination with dirt removing devices of other structures such as the dirt removing device 120 of the embodiment II, the dirt removing device 110 of the modified embodiment.

Further, in the present embodiment, the heating device 101 has a circular shape in plan view, but may be rectangular in plan view. In this case, one side of the member for arranging the absorbing pad is connected to other constituent elements of the heating device (the device body cover, the decorative plate, the heating plate, the first heat insulating material, the heater, the second heat insulating material, the heating device body) via a hinge or the like. And it is preferred that the member for arranging the absorbing pad is foldable with the absorbing pad being clamped with respect to other constituent elements of the heating device 101.

Although the embodiment of the present disclosure has been described above, the specific configuration of each part is not limited to the above described embodiment.

For example, although in the dirt removing devices 100 to 120 of the above described embodiments, the beating surface 21a of the head 11 faces downward, a structure in which the beating surface 21a faces laterally may be used. In this case, the liquid is transferred by, for example, a pump.

In the above embodiments, although a projections 21a1 is formed on the beating surface 21a of the heads 5, 8, 11 (see FIGS. 1, 6, 7, etc.), the beating surface 21a may be flat without the projections 21a1.

In addition, the waterproof cover 50 shown in FIG. 2, etc. may have a built in heater. In this case, preferably, the heater is an annular heater composed of wound nickel-chrome alloy wire or a ceramic heater which generate heat by the power of a power portion. In addition, the power supplied to the heater is, for example, about 5 W, and the temperature of the heater during heat generation is set to about 80° C. to 100° C.

With such a waterproof cover 50, the waterproof cover 50 presses against the clothing C when performing the dirt removing operation, the cloth C is heated by the heater of the waterproof cover 50, so that even if the heating device 101 shown in FIG. 9 is not additionally used, the dirt portion Sp of the cloth C and its periphery can always be heated by the waterproof cover 50 during the dirt removing operation, thereby achieving miniaturization and further improving the dirt removing effect.

Furthermore, in order to suppress the noise when the dirt removing device is driven, the entirety or nearly entirety of the housing body 33 has a double-layered structure. It is also effective to mount components such as the vibration unit 31 in such a housing body 33. In addition, since the housing body 33 has the double-layered structure, it is possible to hide fixing members such as a screw fixed on the inner layer by the outer layer, thereby improving the appearance of the dirt removing devices 100 to 120.

Still further, although the battery 32 is used as the power supply unit in the above embodiments, the present disclosure is not limited to this. Other configurations may also be used, for example, configuration having a Universal Serial Bus (USB) connector capable of being connected with a USB line, configuration having a power cable having a plug, and configuration of being powered by an external power supply. Therefore, there is no need to install the battery 32 in the device body 3, and the device body 3 can be made more compact.

In the above embodiments, the head 5, 8, 11 is configured to be detachable from the liquid accommodating portion 7, 12, 212, but may be configured to be not detachable.

In the above embodiments, the liquid may be a detergent mixture. In this case, the detergent is continuously supplied to the dirt portion Sp of the cloth C during the dirt removing operation, therefore, the detergent will not disappear from the dirt portion Sp due to vaporization, scattering and the like, thereby maintaining a high dirt removing effect. In addition, there is no need to additionally provide a unit for supplying the detergent to the dirt portion Sp, thereby simplifying the device structure.

In the above embodiments, the liquid storage portion 24 and the base end 11a of the head 11 are connected via the cylinder water supplying hole 28 (see FIG. 2). However, the liquid storage portion 24 and the head 11 may be directly connected without the cylinder water supplying hole 28, so that the liquid is directly supplied from the liquid storage portion 24 to the head 11.

Furthermore, at least a part of the cassette mechanism 1, 10, 20 may be a disposable structure (a structure in which the liquid stored in the liquid storage portions 7, 12, 212 in advance cannot be replenished).

Still further, the materials of the members constituting the dirt removing devices 100 to 120 and the heating device 101 are not limited to those materials shown by hatching in the each accompanying drawing.

Other configurations can be variously modified without departing from the spirit of the present disclosure.
