Description
TECHNICAL FIELD

The invention belongs to the technical field of clothing treatment, and in particular relates to a foam local cleaning device and a washing machine.


BACKGROUND

A washing machine is a machine that uses mechanical force generated by electricity to clean laundry. For clothes such as shirts, collars and cuffs are generally dirtier than other parts of the clothes. However, existing washing machines have poor cleaning effects on local parts of the clothes such as collars and cuffs during the washing process.


In the prior art, it is often necessary to achieve the purpose by additionally installing ultrasonic washing on the washing machine.


For example, a Chinese patent application number CN2017101131757 discloses a local clothing cleaning structure and a washing machine, wherein the local clothing cleaning structure is detachably arranged on a washing machine tray seat and connected to a water inlet circuit/detergent box of the washing machine, wherein the local clothing cleaning structure comprises a pressing plate and a supporting plate, wherein the pressing plate comprises an ultrasonic transducer, and the supporting plate comprises a water inlet cavity, and the shape of the pressing plate matches the supporting plate, and after being pressed toward the supporting plate, fine gaps are formed between the pressing plate to clamp the local clothing to be washed, thereby clamping the clothing and ultrasonically cleaning the local clothing to be washed.


Although the above solution solves the problem that the washing machine cannot clean the local area with high dirtiness to a certain extent, it is necessary to disassemble and assemble the local cleaning structure of the clothes according to the cleaning requirements, which is inconvenient for users.


A Chinese patent application numbered CN201810509321.2 discloses a washing machine with a local pre-washing function, the washing machine comprising an ultrasonic washing device; the washing machine has a storage space for accommodating the ultrasonic washing device, and the ultrasonic washing device can be screwed in/out of the storage space.


Although the above solution solves the problem that the washing machine cannot clean local areas with high dirtiness to a certain extent, the additional installation of ultrasonic washing on the washing machine undoubtedly increases the cost of the washing machine and reduces the market competitiveness of the washing machine; in addition, it is difficult to ensure that the ultrasonic washing device will not be touched after being rotated into the accommodating space, resulting in accidental activation of the ultrasonic washing device.


In view of this, the present invention is proposed.


SUMMARY

The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a foam local cleaning device capable of transmitting position information of a foam cleaning component, thereby ensuring that the foam cleaning component is opened or closed in place.


In order to solve the above technical problems, the first aspect of the present invention provides a foam local cleaning device, comprising:

DETAILED DESCRIPTION

In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention but are not used to limit the scope of the present invention.


In the description of the present invention, it should be noted that the directions or positional relationships indicated by terms such as “upper”, “lower”, “front”, “back”, “left”, “right”, “vertical”, “inside” and “outside” are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.


In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms “installed”, “connected”, and “connected” should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.


As shown in FIGS. 1 to 9, the present invention provides a foam local cleaning device, comprising: a housing 1 having a containing cavity; a foam cleaning component 2 being connected to the housing 1 and movable relative to the housing 1, at least for providing foam detergent during local cleaning; and a signal transmission unit, which transmits a signal to the foam local cleaning device when the foam cleaning component 2 moves to a set position.


The signal transmission unit includes a microswitch 6, and the transmitted signal includes an electrical signal; the microswitch 6 is electrically connected to the foam cleaning component 2, and can control the on-off state of the foam cleaning component 2 circuit according to the position of the foam cleaning component 2.


Of course, the microswitch 6 can also be connected to the foam cleaning component 2 for communication. When the foam cleaning component 2 reaches the set position, the microswitch 6 is triggered, and the position of the foam cleaning component 2 can be transmitted to the foam local cleaning device to ensure that the foam cleaning component 2 reaches the set position. When the foam cleaning component 2 moves to the first set position, the foam cleaning component 2 is in a state that cannot be activated; when the foam cleaning component 2 is not in the first set position and/or in the second set position, the foam cleaning component 2 is in a state that can be activated.


The microswitch 6 of the present invention can control the on/off state of the circuit of the foam cleaning component 2 according to the position of the foam cleaning component 2, instead of manually connecting the circuit of the foam cleaning component 2, which not only saves energy consumption, but also reduces the probability of false start-up of the foam cleaning component 2, and also saves the user the step of connecting the circuit, making it easier for the user to operate.


The microswitch 6 can also be manually controlled by the user. When the foam cleaning component 2 moves to the first set position, the user manually triggers the microswitch 6, transmits the position information to the foam local cleaning device or disconnects the circuit, so that the foam cleaning component 2 is in a state that cannot be activated. When the position of the foam cleaning component 2 needs to be changed, the microswitch 6 can be triggered again, and the information that the foam cleaning component 2 is not in the first set position can be transmitted to the foam local cleaning device or the circuit is connected, so that the foam cleaning component 2 can be in a state that can be activated. Or, when the foam cleaning component 2 moves along the set direction to reach the second set position, the microswitch 6 is triggered, and the information that the foam cleaning component 2 is in the second set position can be transmitted to the foam local cleaning device or the circuit is connected, so that the foam cleaning component 2 can be in a state that can be activated.


The housing 1 has a containing cavity 10; the foam cleaning component 2 has a storage position and a cleaning position relative to the housing 1. When at the storage position, the foam cleaning component 2 is accommodated in the containing cavity 10 of the housing 1, and when at the cleaning position, the foam cleaning component 2 is located outside the containing cavity 10 of the housing 1. The microswitch 6 connects the circuit when the foam cleaning component 2 is in the cleaning position, and is in an open circuit state when the foam cleaning component 2 is in the storage position.


The storage position is configured as the first set position, and the cleaning position is configured as the second set position.


This solution ensures that the foam cleaning component 2 is connected to the circuit when it is in the cleaning position, so as to facilitate local cleaning of the items to be washed. It can also prevent the foam cleaning component 2 from being accidentally activated when it is in the storage position due to the circuit being in the on state, causing the foam detergent to be squeezed out, which not only interferes with the washing progress but also causes the foam local cleaning device itself and the environment in which it is located to be polluted.


Furthermore, the microswitch 6 is arranged on the housing 1 and/or the foam cleaning component 2. When the foam cleaning component 2 moves to the cleaning position and/or the storage position, the microswitch 6 is in a triggered state to control the circuit of the foam cleaning component 2 to be connected or disconnected.


As an implementation scheme, as shown in FIG. 1, the microswitch 6 is a passage switch, which is arranged on the housing 1, and the end of the housing 1 close to the opening of the housing 1 is configured as the front end, and the microswitch 6 is arranged at the front part of the housing 1. Preferably, the microswitch 6 is arranged on the front wall of the containing cavity 10. When the foam cleaning component 2 moves forward to the cleaning position, it collides or touches the microswitch 6, so that the microswitch 6 is opened, and the circuit of the foam cleaning component 2 is connected. Conversely, when the foam cleaning component 2 moves backward from the cleaning position, that is, when the foam cleaning component 2 moves to one side of the storage position, the foam cleaning component 2 disconnects from the microswitch 6, so that the microswitch 6 is closed, and the circuit of the foam cleaning component 2 is in an open circuit state.


As an alternative to the above-mentioned scheme, as shown in FIG. 2, the microswitch 6 is a circuit-breaking switch, which is arranged at the rear of the housing 1. Preferably, the microswitch 6 is arranged on the rear wall of the containing cavity 10. When the foam cleaning component 2 is located in the storage position, it collides or touches the microswitch 6, so that the microswitch 6 is opened, and the foam cleaning component 2 is in a circuit-breaking state. Conversely, when the foam cleaning component 2 moves forward from the storage position, that is, moves to one side of the cleaning position, the foam cleaning component 2 loses contact with the microswitch 6, so that the microswitch 6 is closed, and the circuit of the foam cleaning component 2 is in a circuit-connected state.


Of course, each of the front and rear of the housing 1 can provided with one microswitch 6, which can be configured as a passage switch and a circuit-breaker switch respectively, which can not only ensure that the foam cleaning component 2 is stored in place and opened to the cleaning position, but also further prevent the foam cleaning component 2 from being accidentally activated.


As an alternative to the above two solutions, as shown in FIGS. 3 and 4, the microswitch 6 consists of two parts, namely, a fixed contact 61, which is arranged on the housing 1; a moving contact 62, which is arranged on the foam cleaning component 2 and matches the position of the fixed contact 61. The foam cleaning component 2 drives the moving contact 62 to move to contact the fixed contact 61, and the microswitch 6 is in a closed state, controlling the circuit of the foam cleaning component 2 to be disconnected or connected.


Furthermore, the microswitch 6 is disposed in the containing cavity 10.


Specifically, as shown in FIG. 3 and FIG. 4, the fixed contact 61 is arranged on the inner wall of the containing cavity 10 of the housing 1, and the moving contact 62 is arranged on the portion of the foam cleaning component 2 located in the containing cavity 10. This solution not only facilitates the two contacts of the microswitch 6 to make contact and disconnect, but also plays a role in protecting the microswitch 6.


As shown in FIG. 6, the foam local cleaning device of the present invention further comprises a transmission component 3 connected to the housing 1 and the foam cleaning component 2 for transmitting power between the housing 1 and the foam cleaning component 2 to move the foam cleaning component 2 between the storage position and the cleaning position.


The transmission component 3 of the present invention can transmit power between the housing 1 and the foam cleaning component 2, which is convenient for storing the foam cleaning component 2 and moving the foam cleaning component 2 to the cleaning position for local cleaning of the laundry to be washed, and is convenient for users to operate and use.


In detail, when using the above-mentioned foam local cleaning device, the foam cleaning component 2 is moved from the inside of the housing 1 to the outside of the housing 1 through the transmission component 3, which is convenient for local cleaning or pre-application of detergent. The detergent directly foams and is not easy to fall off the clothes, eliminating the process of dipping water, rubbing and foaming, so that the effective ingredients in the foam are fully utilized, greatly improving the cleaning, sterilization and moisturizing effects.


After use, the foam cleaning component 2 is moved from the outside of the housing 1 to the inside of the housing 1 through the transmission component 3 to avoid the foam cleaning component 2 occupying a large space.


Furthermore, a base 41 is connected to the bottom of the foam cleaning component 2, and the base 41 moves back and forth to drive the foam cleaning component 2 to switch between the storage position and the cleaning position.


The moving contact 62 of the microswitch 6 is arranged on the base 41. Specifically, the moving contact 62 is arranged on a portion of the base 41 that is always located in the containing cavity 10. This solution can reduce the contact between the foam cleaning component 2 and the housing 1, prevent the foam cleaning component 2 from being collided or worn, and play a role in protecting the foam cleaning component 2.


The open end of the housing 1 is configured as the front end of the housing 1, and the end away from the opening of the housing 1 is configured as the rear end of the housing 1; the end of the foam cleaning component 2 opposite to the front end of the housing 1 is the front end of the foam cleaning component 2, and the end opposite to the rear end of the housing 1 is the rear end of the foam cleaning component 2.


As an embodiment, as shown in FIG. 3, the fixed contact 61 and the moving contact 62 of the microswitch 6 are respectively arranged at the front of the housing 1 and the rear of the foam cleaning component 2, and the microswitch 6 is configured as a passage switch. When the foam cleaning component 2 is located at the cleaning position, the fixed contact 61 and the moving contact 62 are in contact, and the circuit of the foam cleaning component 2 is turned on. Specifically, the moving contact 62 of the passage switch is arranged on the bottom wall of the base 41, close to the rear end of the base 41, and the fixed contact 61 of the passage switch is arranged on the front wall of the containing cavity 10, matching the position of the moving contact 62, and is located at the lower part of the front wall of the containing cavity 10.


And/or, the fixed contact 61 and the moving contact 62 of the microswitch 6 are respectively arranged at the rear of the housing 1 and the foam cleaning component 2, and the microswitch 6 is configured as a circuit-breaker switch. When the foam cleaning component 2 is located in the storage position, the fixed contact 61 and the moving contact 62 are in contact, and the circuit of the foam cleaning component 2 is disconnected.


As a preferred solution, as shown in FIG. 4, the microswitches 6 are provided with two groups, which are respectively configured as a passage switch and a circuit-breaker switch. The moving contact 62 of the passage switch is arranged on the bottom wall of the base 41, close to the rear end of the base 41, and the fixed contact 61 of the passage switch is arranged on the front wall of the containing cavity 10, matching the position of the moving contact 62, and located at the lower part of the front wall of the containing cavity 10. The moving contact 62 of the circuit-breaker switch is arranged on the rear wall of the base 41, and the fixed contact 61 is arranged on the rear wall of the containing cavity 10, matching the position of the moving contact 62.


In the first and second implementations, the microswitch 6 is arranged on the base 41, and the base 41 drives the microswitch 6 to touch the inner wall of the containing cavity 10 to trigger the microswitch 6; and/or, the microswitch 6 is arranged on the inner wall of the containing cavity 10, and the base 41 moves to touch the microswitch 6 to trigger the microswitch 6.


As shown in FIG. 5, the foam local cleaning device of the present invention further includes a switch part 7, which is at least used to control the foam cleaning component 2 to start up to provide foam detergent, and control the foam cleaning component 2 to shut down to stop providing foam detergent after the foam cleaning component 2 receives the relevant signal.


Specifically, when the foam cleaning component 2 is in a powered-on state, the switch part 7 can control the foam cleaning component 2 to start up to provide foam detergent, and control the foam cleaning component 2 to shut down to stop providing foam detergent.


The switch part includes a mechanical knob and/or a sensor unit.


When the switch part 7 is a mechanical knob, it is arranged on the foam cleaning component 2, or on the housing 1, or on the tray seat 5 of the washing machine, or on the control panel of the washing machine.


When the switch part 7 is a sensor unit, the switch part 7 is arranged close to the foam cleaning component 2, or is a part of the foam cleaning component 2, and can be extended outward together with the foam cleaning component 2 and be accommodated in the containing cavity 10.


This solution requires turning on the switch part 7 when the circuit is turned on to open the foam cleaning component 2, which is equivalent to setting at least a double switch for the foam cleaning component 2. In particular, when the switch part 7 is a sensor unit, since the sensor unit is relatively sensitive, such as a temperature sensor and an infrared sensor, when the user approaches it, it is easy to be falsely triggered after receiving the temperature or infrared signal. By setting the microswitch 6, the probability of false triggering of the foam cleaning component 2 is reduced.


The transmission component 3 includes: a first meshing unit connected to the housing 1; a second meshing unit connected to the foam cleaning component 2 and meshing with the first meshing unit; the second meshing unit cooperates with the first meshing unit to move the foam cleaning component 2 between the storage position and the cleaning position.


As shown in FIGS. 6 to 8, the foam local cleaning device of the present invention further includes a handle 4 connected to the foam cleaning component 2, and the second meshing unit is disposed on the handle 4.


The foam local cleaning device is a manually controlled structure. Pushing and pulling the handle 4 drives the second meshing unit to move. The first meshing unit cooperates with the second meshing unit to guide the foam cleaning component 2 to move between the storage position and the cleaning position.


When using the above-mentioned foam local cleaning device, the user pulls the handle 4 to move the foam cleaning component 2 from the inside to the outside of the housing 1, while driving the second meshing unit connected to the handle 4 to move horizontally toward the outside of the housing 1 relative to the first meshing unit.


After use, the user pushes the handle 4 to move the foam cleaning component 2 from the outside to the inside of the housing 1, while driving the second meshing unit connected to the handle 4 to move horizontally toward the inside of the housing 1 relative to the first meshing unit.


In an alternative manner, the foam cleaning component 2 can be automatically switched between the storage position and the cleaning position without manual operation by the user, thereby simplifying the user's operation.


In detail, the foam local cleaning device is an automatic control structure, and a driving unit is provided, which is connected to the first meshing unit and/or the second meshing unit to drive the first meshing unit and/or the second meshing unit to move, and the first meshing unit cooperates with the second meshing unit to guide the foam cleaning component 2 to move between the storage position and the cleaning position.


The handle 4 serves as an intermediate structure connecting the foam cleaning component 2 and the transmission component 3. The handle 4 drives the foam cleaning component 2 to move, thereby avoiding that the foam cleaning component 2 is directly connected to the transmission component 3, and preventing the foam cleaning component 2 from contacting and moving relative to the first meshing unit provided on the outer housing 1 during the movement, thereby preventing the foam cleaning component 2 from being worn. In addition, the handle 4 is provided to facilitate the user to manually push and pull the foam cleaning component 2.


When the foam local cleaning device is an automatic control structure, the handle 4 may not be provided. In order to prevent the foam cleaning component 2 from being worn, a base 41 may be provided at the bottom of the foam cleaning component 2 and connected to the foam cleaning component 2. The base 41 moves to drive the foam cleaning component 2 to move between the storage position and the cleaning position.


As shown in FIG. 6 and FIG. 7, the first meshing unit includes a gear disposed on the housing 1; the second meshing unit includes a rack 34 meshingly connected to the gear, and the rack 34 is connected to the foam cleaning component 2 and moves together.


Furthermore, the rack 34 is disposed on the base 41.


Alternatively, the rack 34 is arranged on the housing 1, and the gear is arranged on the base 41. The gear rotates forward and reversely while moving back and forth on the rack 34, so that the foam cleaning component 2 moves relative to the housing 1 to switch between the storage position and the cleaning position.


The meshing connection of the gear rack 34 of the present invention can realize power transmission between the foam cleaning component 2 and the housing 1, which can not only ensure the connection effect of the foam cleaning component 2 and the housing 1, but also drive the foam cleaning component 2 to move linearly.


As shown in FIG. 6 and FIG. 7, the handle 4 includes the base 41 and a connecting wall 43.


The base 41 is arranged below the foam cleaning component 2, and a hollow portion 42 is provided at a position corresponding to the foam cleaning component 2 to allow water of the foam cleaning component 2 to flow through. The rack 34 is arranged on the side wall of at least one side of the base 41; the gear is arranged in the containing cavity, corresponding to the position of the rack 34, and located on the same side.


The connecting wall 43 is located between the foam cleaning component 2 and the base 41, and is connected to the foam cleaning component 2 and the base 41 respectively.


In the above solution, the user pushes and pulls the base 41 to move the foam cleaning component 2 between the storage position and the cleaning position, thereby improving stability during operation.


In addition, a hollow portion 42 is provided on the base 41, so that the water flow generated by the foam cleaning component 2 can flow away in time, thereby preventing foam from accumulating and adhering to the foam cleaning component 2, causing blockage and other problems.


As an implementation scheme, the rack 34 is arranged on the side walls on the left and right sides of the base 41, and the gear is arranged in the containing cavity, corresponding to the position of the rack 34, and is located on the left and right sides of the base 41 respectively.


As shown in FIGS. 6 and 7, the radial direction of the gear is arranged along the vertical direction of the containing cavity; the rack 34 is located above and/or below the gear and is meshed with the gear in the vertical direction. This solution reduces the space occupied by the transmission component 3, making the overall structure of the foam local cleaning device more compact.


Furthermore, as shown in FIGS. 6 and 7, two racks 34 are provided on one side of the base 41, and the two racks 34 are arranged in parallel with teeth facing each other; there are at least two gears arranged on this side of the containing cavity, which are located between the two racks 34 and are respectively connected to the two racks 34.


There are two sets of racks 34 and gears on the same side of the foam cleaning component 2, which can ensure that the foam cleaning component 2 moves in a straight line and improve the stability of the foam cleaning component 2 during movement.


When the foam cleaning component 2 is a manually controlled structure, there are two gears, which are respectively connected to two racks 34, with a gap between the two gears, or the two gears are meshed and connected; or, there are at least three gears, two of which are connected to a rack 34 and configured as a positioning wheel 32, and each gear cooperates with the two racks 34 to orient the movement direction of the foam cleaning component 2. Preferably, there is a gap between the two positioning wheels 32.


When the foam cleaning component 2 is an automatic control structure, the driving unit is arranged on the housing 1 and is connected to one of the gears to drive the gear to rotate. The gear is configured as a driving wheel 31, and the driving wheel 31 is connected to one of the racks 34. There are two gears, and the other gear is meshed and connected with the driving wheel 31, configured as a driven wheel 33, and connected to the other rack 34. Or, there are three gears, and the other two gears are connected to the other rack 34, configured as a positioning wheel 32, and the driving wheel and the positioning wheel 32 respectively cooperate with the two racks 34 to orient the movement direction of the foam cleaning component 2. Preferably, there is a distance between the two positioning wheels 32.


As an implementation scheme, the driving unit is a motor.


When the foam cleaning component 2 is an automatic control structure, the transmission component 3 also includes a control switch 35, which is electrically connected to the driving unit and is used to control the switch of the driving unit. The user can manually control the opening and closing of the control switch 35, or the control switch 35 is controlled by a washing program and/or infrared and/or voice and/or a mobile terminal.


The control switch 35 is arranged on the housing 1, or on the base of the washing machine, or on the control panel of the washing machine.


The driving unit of the present invention can realize automatic control of the foam cleaning component 2, and the arrangement of the two positioning wheels 32 can ensure that the foam cleaning component 2 moves stably and smoothly without deflection, and has high reliability.


As an implementation scheme, the distance between the two racks 34 is the minimum distance that can accommodate the driving wheel 31 and the positioning wheel 32. This solution enables the foam cleaning component 2 to obtain sufficient driving force for its movement when the driving device has the minimum driving force, thereby saving electric energy, reducing the damage of the equipment, and extending the service life of the entire foam cleaning component 2.


A limiting portion is provided on the housing 1, and a first positioning portion and a second positioning portion are respectively provided at the front and rear ends of the handle 4. The first positioning portion and the second positioning portion cooperate with the limiting portion to enable the foam cleaning component 2 to move within a set range, thereby preventing the foam cleaning component 2 from detaching from the housing 1 or colliding inwardly against the rear wall of the housing 1.


Furthermore, the limiting portion can control the on and off state of the motor.


A touch switch for turning the motor on and off is provided on the limit portion. When the first positioning portion or the second positioning portion touches the touch switch, it will be normally open/or normally closed. The computer board can determine whether the position of the foam cleaning component 2 is the storage position or the cleaning position. Pressing the control switch 35 once can directly drive the foam cleaning component 2 to open or disconnect; in other states, the control circuit of the drive unit is in a power-off shutdown state.


Furthermore, the clockwise rotation state and the counterclockwise rotation state of the motor are alternately changed in sequence with the pressing of the control switch 35. Pressing the control switch 35 once starts the motor to rotate clockwise, and pressing it again starts the motor to rotate counterclockwise, and the two are performed alternately. When the control switch 35 is pressed for the first time, the motor starts to operate, and the driving wheel 31 on the motor drives the rack 34 connected to the driving wheel 31 to move toward the outside of the housing 1. When the foam cleaning component 2 is opened to a certain position, the first positioning part touches the touch switch on the limiting part, disconnecting the switch, and the foam cleaning component 2 stops moving. When the control switch 35 is pressed again, the motor starts to operate, and the driving wheel 31 on the motor drives the rack 34 connected to it to move in the opposite direction. When the foam cleaning component 2 is closed to a certain position, the second positioning part touches the touch switch on the limiting part, disconnecting the control circuit, and the foam cleaning component 2 stops moving. The foam cleaning component 2 is closed in place and is in the storage position.


As shown in FIG. 8, the housing 1 of the present invention is provided with a door body 11, which is arranged at the opening of the containing cavity, and the upper end is connected to the upper end of the opening, and is used to block the containing cavity when the foam cleaning component 2 is in the storage position, and open the opening of the housing 1 when the foam cleaning component 2 is moved outward from the storage position.


As shown in FIG. 9, the foam cleaning component 2 includes: a water outlet unit for providing cleaning water during local cleaning; and a foam generating unit 23 for providing foam detergent during local cleaning.


The switch part 7 is provided with a mechanical knob for controlling the opening and closing of the water outlet unit and the foam generating unit 23. The operation mode includes triggering the switch part 7 once to control the opening of the foam generating unit 23, triggering the switch part 7 again to control the closing of the foam generating unit 23; triggering the switch part 7 twice continuously to control the opening of the water outlet unit, and triggering the switch part 7 twice continuously to control the closing of the water outlet unit.


Alternatively, as shown in FIG. 5, two switch parts 7 are provided, which are mechanical knob and/or sensor unit, and two switch parts respectively used to control the opening and closing of the water outlet unit and the foam generating unit 23. Specifically, the switch part 7 for controlling the water outlet unit controls the water outlet unit to discharge water after being turned on; the switch part 7 for controlling the foam generating unit 23 controls the foam generating unit 23 to generate foam detergent after being turned on.


The foam generating unit 23 has a liquid outlet 231, which is disposed on a side of the foam generating unit 23 away from the rear wall of the containing cavity 10 and is used for discharging foam detergent.


Furthermore, a shell 25 is provided above the foam generating unit 23.


When the switch part 7 is a mechanical knob, it is arranged on the housing 25, and the liquid outlet 231 faces downward. Specifically, the switch part 7 is arranged on the outer wall of the housing 25. The housing 25 plays a role in protecting the foam generating unit 23. The switch part 7 is arranged on the housing 25, which can reduce the user's contact with the foam generating unit 23 and further play a role in protecting the foam generating unit 23.


As shown in FIG. 9, when the switch part 7 is a sensor unit, it is disposed below the housing 25 and can be covered by the housing 25, which not only reduces the probability of the sensor unit being triggered by mistake, but also plays a role in protecting the sensor unit.


As an implementation scheme, as shown in FIG. 9, the shell 25 is also provided under the foam generating unit 23. The two shells 25 are respectively distributed on the upper and lower sides of the foam generating unit 23 and the switch part 7, and are both located above the base 41. The two shells 25 can cooperate to cover the upper and lower sides of the foam generating unit 23 and the switch part 7.


In some embodiments of the present invention, the foam cleaning component 2 includes a water outlet unit, a first sensing unit, a foam generating unit and a second sensing unit.


In detail, the water outlet unit is used to provide washing water during local washing; the first sensing unit is used to trigger the water outlet unit to discharge water when sensing clothes; the foam generating unit is used to provide foam detergent during local washing; and the second sensing unit is used to trigger the foam generating unit to generate foam detergent when sensing clothes.


In the above scheme, the foam generating unit and the water outlet unit for spraying detergent and water are respectively controlled by the sensing device to be started or not. During the local cleaning process, the processes of wetting the clothes and adding detergent can be performed alternately to improve the cleaning effect on the local position.


In a further solution, the foam generating unit and the second sensing unit are arranged in the shell, the outlet of the foam generating unit and the sensing end of the second sensing unit are arranged on the bottom wall of the shell, and the outlet of the foam generating unit is located at a position away from the connecting wall 43 relative to the sensing end of the second sensing unit.


In the above solution, the foam generating unit and the second sensing unit are integrated into one shell, and only an outlet for the detergent foam is reserved on the bottom wall of the shell, thereby improving the overall aesthetics of the device and enhancing the user experience.


Furthermore, by arranging the outlet of the foam generating unit at a position away from the connecting wall 43 relative to the sensing end of the second sensing unit, it is possible to avoid the situation where detergent foam begins to be produced before the clothes reach the outlet of the foam generating unit.


In a further solution, the water outlet unit and the first sensing unit are integrated into one body and are located below the shell and avoid the outlet of the foam generating unit and the sensing end of the second sensing unit.


In the above solution, the water outlet unit and the first sensing unit are integrated into one body, which can also improve the overall aesthetics of the device and enhance the user experience.


Moreover, by arranging the components for discharging water and the components for discharging detergent in an upper and lower position, the size of the foam local cleaning device in the width direction can be reduced, which is conducive to installing the foam local cleaning device on a structure such as a dish seat of a washing machine.


The avoidance method may be, for example, setting the sizes of the water outlet unit and the first sensing unit to be smaller than the sizes of the foam generating unit and the second sensing unit.


As shown in FIG. 1 to FIG. 9, another object of the present invention is to provide a washing machine having the above-mentioned foam local cleaning device.
