20250214358
The present application is based on, and claims priority from JP Application Serial Number 2023-222300, filed Dec. 28, 2023, the disclosure of which is hereby incorporated by reference herein in its entirety.
The present disclosure relates to a deodorization cartridge and a recording device.
In the related art, a recording device that records characters or images and has a function of purifying odors caused by recording materials is known. For example, JP-A-2018-140530 discloses a printing device that includes a printing unit, a housing that accommodates the printing unit, and a gas purification unit that purifies gas. The gas purification unit is located outside the housing and communicates with the inside of the housing via an exhaust unit and a supply unit. This printing device decomposes or removes odors of a gas inside the housing using a deodorizing agent such as an activated carbon or an ozone oxidizer.
However, when a recording device is transported or a deodorization cartridge is attached to the recording device, fine powder may be generated when a deodorization body is rubbed due to vibration and the generated fine powder may leak to the outside.
The present disclosure is a deodorization cartridge for a recording device, including: an accommodation body including a handle and an opening portion for ventilation, and a deodorization unit accommodated in the accommodation body, wherein the deodorization unit includes a deodorization body, and a first elastic body and a second elastic body disposed on both sides of the deodorization body in a first direction, the first elastic body and the second elastic body are accommodated in the accommodation body in an elastically deformed state, and the opening portion causes air in the accommodation body to flow therethrough in the first direction.
The present disclosure is a recording device including a medium support portion configured to support a medium, a recording unit configured to perform recording on the medium using a liquid, an irradiation unit configured to irradiate the medium with ultraviolet light, and a deodorization cartridge configured to deodorize odors generated from the liquid, wherein the deodorization cartridge includes an accommodation body including a handle and an opening portion for ventilation, and a deodorization unit accommodated in the accommodation body, the deodorization unit includes a deodorization body, and a first elastic body and a second elastic body disposed on both sides of the deodorization body in a first direction, the first elastic body and the second elastic body are accommodated in the accommodation body in an elastically deformed state, and the opening portion causes air in the accommodation body to flow therethrough in the first direction.
A configuration of the recording device 1 of an embodiment will be described below with reference to the accompanying drawings.
The recording device 1 is a device that performs recording on a medium M supported by a medium support portion 30 by ejecting a liquid from a recording head 89a. The medium M is a sheet, a cloth, or a three-dimensional object. The sheet may be paper or a sheet made of synthetic resin. The fabric may be nonwoven, knitted, or woven. The three-dimensional object may be an ornament such as clothing or shoes, daily necessities, machine parts, or various other objects. There is no restriction on a type of liquid that the recording device 1 ejects onto the medium M as long as the liquid has fluidity. For example, the recording device 1 is a printer that ejects one or more colors of ink onto a front surface of the medium M using the recording head 89a to form an image on the medium M. In this case, the medium M can be called a print medium.
The recording device 1 includes a housing 10. The housing 10 is a substantially rectangular box and forms a closed space inside the housing 10. The housing 10 covers a medium support portion 30, the recording head 89a, an irradiation unit 89b, a first deodorization mechanism 20, and a second deodorization mechanism 50, which will be described later, and stores these in a closed space. The housing 10 includes a front cover 11 along a front surface 10a and a top surface 10b. The front cover 11 includes a cover body 11a along the front surface 10a and the top surface 10b, and a handle 11b coupled to a lower end of the cover body 11a. The front cover 11 is coupled to the top surface 10b of the housing 10 by a hinge at a rear end of the cover body 11a so that the front cover 11 can be rotated about the left-right direction. Therefore, when the handle 11b moves in an up-down direction, the front cover 11 can be opened and closed from the forward direction. Further, the housing 10 includes a bottom plate 13 on a bottom surface 10c, which is a plate that faces an installation surface of the housing 10. The installation surface is a surface on which the housing 10 is installed, such as a top surface of a desk (not shown).
The recording device 1 includes a touch panel 12 disposed in a front portion of the top surface 10b. The touch panel 12 includes, for example, a liquid crystal panel and light emitting diodes (LEDs). The touch panel 12 is coupled to a control unit 100 installed inside the housing 10. The touch panel 12 includes a touch sensor that detects a touch operation with respect to a front surface of the touch panel 12 and a display panel that are superimposed on each other. The display panel of the touch panel 12 is, for example, a liquid crystal panel. The control unit 100 causes display of characters or images via control of the display panel of the touch panel 12. The control unit 100 also detects the touch operation with respect to the touch panel 12 and specifies an operation position of the touch operation. The control unit 100 causes the touch panel 12 to display information such as the progress of recording in the recording device 1, and a remaining amount of liquid to be ejected during recording. Further, the control unit 100 causes the touch panel 12 to display information on a replacement timing of consumables of the first deodorization mechanism 20 and the second deodorization mechanism 50 to be described below.
As illustrated in
The first deodorization mechanism 20 and the second deodorization mechanism 50 suck air inside the housing 10 and remove odors contained in the sucked air, thereby deodorizing the air and exhaust the air to the outside of the housing 10. Details of the first deodorization mechanism 20 and the second deodorization mechanism 50 will be described later.
The medium support portion 30 supports the medium M that is a recording target in the recording device 1. As illustrated in
The support surface 31m is a surface on which the medium M is placed in the medium support portion 30, and supports the medium M placed on the support surface 31m. As illustrated in
The table 31 includes protrusions 31n that protrude outward from the support surface 31m in a plan view in lower portions at four corners of the support surface 31m. The table 31 is supported to be raised or lowered with respect to the base member 15 by the protrusions 31n being fixed to a lifting mechanism 39 to be described later.
The fall prevention plate 34 is a plate-like member that is vertically erected in contact with left, right, and rear sides of the support surface 31m. In other words, the fall prevention plate 34 is perpendicular to the support surface 31m, and surrounds the support surface 31m in a left-right direction and the rear side along ends of the support surface 31m, and the front side of the support surface 31m is open without the fall prevention plate 34.
The fall prevention plate 34 is formed, for example, by a single sheet of metal being bent. The fall prevention plate 34 is disposed around the support surface 31m, for example, so that the medium M, which is greatly smaller than the support surface 31m, does not fall from the support surface 31m. The support surface 31m can be raised or lowered as described later, and the fall prevention plate 34 is fixed not to be raised or lowered. The fall prevention plate 34 extends in a range including a lowest position to a highest position of the support surface 31m in a height direction. Therefore, at least a portion of the fall prevention plate 34 is located above the support surface 31m when the support surface 31m is at a lowest position.
The height movement mechanism 32 raises and lowers the table 31 up and down. The height movement mechanism 32 can move the support surface 31m up and down and raise and lower the medium M supported on the support surface 31m by raising and lowering the table 31. The height movement mechanism 32 includes a lifting motor 33, a lifting belt 37, and the lifting mechanism 39. The lifting mechanism 39 includes ball screws disposed along a vertical direction, nuts screwed to the ball screws, and a pulley. The ball screw of the lifting mechanism 39 is rotatably supported by the base member 15. The nut of the lifting mechanism 39 is fixed to the protrusion 31n of the table 31. The recording device 1 includes a set of lifting mechanisms 39 each including the ball screw, a nut, and a pulley, for example, to correspond to four protrusions 31n provided at four corners of the table 31. The pulley of the lifting mechanism 39 is fixed to an upper portion of the ball screw. When the pulley of the lifting mechanism 39 rotates, the ball screw rotates, and the protrusion 31n moves in a vertical direction together with the nut as the ball screw rotates.
The lifting motor 33 is a motor that rotates under the control of the control unit 100. The control unit 100 controls a direction and amount of rotation of the lifting motor 33. The lifting belt 37 is a circular belt that is hung around an output shaft of the lifting motor 33 and the pulleys of the four lifting mechanisms 39. The lifting belt 37 is driven in a circulating manner as the lifting motor 33 rotates. The lifting belt 37 transfers the rotation of the lifting motor 33 to the pulleys of the four lifting mechanisms 39. Accordingly, the ball screw of the lifting mechanism 39 rotates to move the table 31 in a vertical direction. Since the four lifting mechanisms 39 are operated in conjunction with each other by the lifting belt 37 to move the table 31, for example, the table 31 can be raised and lowered with the horizontality of the support surface 31m maintained.
The rotation direction of the lifting motor 33 can be switched between a forward direction in which the table 31 is moved upward, and a backward direction in which the table 31 is moved downward. The recording device 1 raises and lowers the table 31 by operating the lifting motor 33.
The drive mechanism 90 includes a pair of guide shafts 91 and a frame drive unit 60. The guide shaft 91 is a shaft-shaped member that is hung across the pair of base members 15 and disposed along the front-rear direction.
The frame drive unit 60 includes a frame movement motor 61, a transfer belt 63, a speed change mechanism 65, and a transfer belt 67. The frame movement motor 61 is a motor that rotates under the control of the control unit 100. The transfer belt 63 is a circular belt that is hung between an output shaft of the frame movement motor 61 and the speed change mechanism 65, and transfers a driving force of the frame movement motor 61 to the speed change mechanism 65. The speed change mechanism 65 includes a first pulley and a second pulley, and the transfer belt 63 is wound around the first pulley and the transfer belt 67 is wound around the second pulley. The speed change mechanism 65 drives the transfer belt 67 by rotating the second pulley with a driving force transferred from the transfer belt 63 to the first pulley. The speed change mechanism 65 transfers a driving force of the frame movement motor 61 to the transfer belt 67 at a deceleration ratio corresponding to a ratio of diameters of the first pulley and the second pulley.
The transfer belt 67 is a circular belt that is hung between the speed change mechanism 65 and a frame movement pulley 17 that is disposed at an end of the base member 15 in a backward direction. The frame movement pulley 17 is a pulley that is rotatably installed on the base member 15. The transfer belt 67 is disposed along the guide shaft 91.
The moving portion 70 includes a main frame 71, a pair of leg portions 73, and a carriage 89. The main frame 71 is a plate-shaped member that is long in a left-right direction. The pair of leg portions 73 can be fitted into the pair of guide shafts 91 and moved along the guide shafts 91. The main frame 71 is fixed onto the pair of leg portions 73 and supported from a downward side by the pair of leg portions 73. The main frame 71 is guided by the pair of guide shafts 91 together with the pair of leg portions 73 and moved in the front-rear direction.
Among the pair of leg portions 73, the leg portion 73 that supports a left end of the main frame 71 is fixed to the transfer belt 67 via a belt coupling portion 79. Therefore, when the transfer belt 67 is driven in a circulating manner, a force for moving the leg portion 73 in the front-rear direction acts on the leg portion 73. Accordingly, the moving portion 70 moves in the front-rear direction. The lower end of the main frame 71 is located above the support surface 31m when the table 31 is located at an uppermost position. The main frame 71 therefore moves above the support surface 31m in the front-rear direction without interfering with the support surface 31m.
A rotation direction of the frame movement motor 61 can be switched between a forward direction in which the main frame 71 is moved forward and a backward direction in which the main frame 71 is moved backward. The recording device 1 moves the main frame 71 forward and backward by operating the frame movement motor 61.
The carriage 89 is a substantially rectangular box, and is supported by the main frame 71 via a carriage guide shaft 83. The carriage guide shaft 83 is an axial member fixed to the main frame 71, and extends in a left-right direction along the main frame 71. The carriage guide shaft 83 supports the carriage 89 so that the carriage 89 can move in a left-right direction. A lower end of the carriage 89 is located above the support surface 31m when the table 31 is located at an uppermost position. Therefore, the carriage 89 moves above the support surface 31m in the front-rear direction and the left-right direction without interfering with the support surface 31m.
Further, the carriage 89 is coupled to a carriage drive belt 85. The carriage drive belt 85 is a circular belt that is disposed along the carriage guide shaft 83, with one end hung around a carriage drive pulley 86 and the other end hung on an output shaft of a carriage drive motor 87. The carriage drive pulley 86 is a pulley that is rotatably fixed to a right end of the main frame 71. The carriage drive motor 87 is a motor that is fixed to the left end of the main frame 71 and rotates the output shaft under the control of the control unit 100. The carriage drive motor 87 drives the carriage drive belt 85 in a circulating manner by rotating the output shaft. Accordingly, the carriage drive motor 87 moves the carriage 89 coupled to the carriage drive belt 85 in the left-right direction along the carriage guide shaft 83.
The drive mechanism 90, the carriage drive belt 85, the carriage drive pulley 86, and the carriage drive motor 87 correspond to an example of a moving mechanism that moves the carriage 89 relative to the medium M.
The carriage 89 includes the recording head 89a and the irradiation unit 89b. The recording head 89a includes a plurality of nozzles (not shown) that open downward from a lower end surface of the carriage 89. The recording head 89a ejects liquid from these nozzles according to driving of a piezoelectric actuator (not shown). When the recording head 89a ejects the liquid from the nozzles, the ejected liquid flies between the nozzles and the medium M placed on the table 31 and is dropped onto the medium M. In the present embodiment, the liquid ejected from the nozzles by the recording head 89a is ink that is cured by ultraviolet light. The recording head 89a records characters or images formed by the liquid on the medium M by causing the liquid to be dropped onto the medium M on the medium support portion 30. The recording head 89a corresponds to an example of a recording unit.
The irradiation unit 89b includes an irradiation window (not shown) that faces the downward side from the lower end surface of the carriage 89. The irradiation window includes a plate made of a light-transmitting material. The irradiation unit 89b emits irradiation light from a light source unit (not shown) through the irradiation window. The irradiation light emitted from the irradiation unit 89b passes an area between the irradiation window and the medium M placed on the table 31, and is radiated onto the medium M recorded by the recording head 89a. In the present embodiment, the irradiation unit 89b includes ultraviolet light emitting diode (UV-LED) that emits ultraviolet light, and the irradiation light is ultraviolet light. That is, in the present embodiment, the irradiation unit 89b irradiates the ink dropped onto the medium M and cured by ultraviolet light with the ultraviolet light, thereby adhering the ink to the medium M.
The ink ejected by the recording head 89a is a so-called UV ink that is cured by being irradiated with the ultraviolet light. Some UV inks have a unique odor. When the recording device 1 performs recording on the medium M using such an ink, the odor of the ink is present inside the housing 10. The recording head 89a moves in a front-rear direction and a left-right direction during recording, so that the odor of the ink is diffused inside the housing 10. The first deodorization mechanism 20 and the second deodorization mechanism 50 remove the odor emitted by the ink by sucking in the air inside the housing 10, and discharge the purified air.
The first deodorization mechanism 20 is disposed on the left side of the medium support portion 30 as illustrated in
The second deodorization mechanism 50 is disposed behind the medium support portion 30, as illustrated in
One of the first deodorization mechanism 20 and the second deodorization mechanism 50, which are the two deodorization mechanisms of the recording device 1 is at a position aligned with the support surface 31m in the direction along the X-axis, and the other is at a position aligned with the support surface 31m in the direction along the Y-axis. The first deodorization mechanism 20 is at a position suitable for deodorization of odors that are diffused by the carriage 89 moving along the X-axis. The second deodorization mechanism 50 is at a position suitable for deodorization of odors that are diffused by the carriage 89 moving along the Y-axis together with the moving portion 70. Thus, the first deodorization mechanism 20 and the second deodorization mechanism 50, which are a plurality of deodorization mechanisms, are disposed at positions aligned with the medium support portion 30 in the direction along the X-axis and positions aligned with the medium support portion 30 in the direction along the Y-axis, so that the air inside the housing 10 can be deodorized efficiently.
The first deodorization mechanism 20 and the second deodorization mechanism 50 are fixed to the base member 15 or the bottom plate 13 by a means such as screws.
In the configuration illustrated in
In the configuration illustrated in
In other words, the first deodorization mechanism 20 and the second deodorization mechanism 50 are disposed to face one of the four sides constituting the periphery of the table 31. In this configuration, the first deodorization mechanism 20 and the second deodorization mechanism 50 are disposed so that a side of the table 31 facing the first deodorization mechanism 20 and a side of the table 31 facing the second deodorization mechanism 50 do not face each other.
Further, in the configuration illustrated in
The first deodorization mechanism 20 and the second deodorization mechanism 50 have a common configuration. Hereinafter, a configuration of the first deodorization mechanism 20 will be described, but the description also applies to the second deodorization mechanism 50.
An up-down direction in
The first deodorization mechanism 20 includes an accommodation portion 21, a lid portion 23, a first blower 27, and a duct 29. The second deodorization mechanism 50 includes an accommodation portion 51, a lid portion 53, a second blower 57, and a duct 59. The first blower 27 and the second blower 57 correspond to blower fans.
The accommodation portion 21 has a substantially box shape and includes a front surface 21a, a side surface 21b, a side surface 21d, a rear surface 21c, and a bottom surface 21e. The front surface 21a, the side surface 21b, the side surface 21d, the rear surface 21c, and the bottom surface 21e are all made of a surface material made of a non-flammable or flame-retardant material. For example, the accommodation portion 21 is made of a metal plate such as a steel plate. A top surface of the accommodation portion 21 is open, and the lid portion 23 is disposed to cover this opening.
The front surface 21a is a surface that faces the rear surface 21c, and the side surface 21b is a surface that faces the side surface 21d. Lid support portions 21f are provided at upper ends of the side surfaces 21b and 21d. The lid support portions 21f protrude toward the outside of the accommodation portion 21 at the side surfaces 21b and 21d. The lid support portion 21f on the side surface 21b and the lid support portion 21f on the side surface 21d face each other.
The lid portion 23 has a configuration in which a tip panel 23a and a base panel 23b are included and are coupled by a hinge portion 23c. A base end portion of the base panel 23b is pivotably coupled to the lid support portion 21f on the side surface 21b and the lid support portion 21f on the side surface 21d via the support portion 23e. A tip end portion of the base panel 23b is pivotably coupled to a base end portion of the tip panel 23a by the hinge portion 23c. Accordingly, the tip panel 23a and the base panel 23b are pivotable relative to each other, and the base panel 23b is pivotable relative to the accommodation portion 21. The tip panel 23a and the base panel 23b are made of, for example, a synthetic resin. The tip panel 23a and the base panel 23b may be made of a surface material made of a non-flammable or flame-retardant material, like the front surface 21a, the side surfaces 21b and 21d, the rear surface 21c, and the bottom surface 21e.
The tip panel 23a has a concave portion 23d formed therein. The concave portion 23d is used for a user to place his or her finger when the user opens the lid portion 23.
A first intake port 25 opens in an upper portion of the accommodation portion 21. The first intake port 25 is an opening formed by cutting out a part in an upper portion of the front surface 21a. In the present embodiment, the first intake port 25 is formed only at the front surface 21a, and not on the rear surface 21c. The front surface 21a is a surface that faces the medium support portion 30 in a state in which the first deodorization mechanism 20 is mounted on the recording device 1. The first intake port 25 can also be provided on a surface other than the front surface 21a in the accommodation portion 21. However, an air flow in the first deodorization mechanism 20 can be limited to a specific direction, and deodorization in the first deodorization mechanism 20 can be performed more efficiently by providing the first intake port 25 only on the front surface 21a.
The deodorization cartridge 40 is accommodated in the accommodation portion 21. The first intake port 25 opens on the side surface 21b, so that a top surface of the deodorization cartridge 40 is exposed inside the housing 10. The deodorization cartridge 40 is removably accommodated in the accommodation portion 21, and the deodorization cartridge 40 can be replaced.
Further, the deodorization cartridge 40 is accommodated in the accommodation portion 21 through resin member for shake prevention 109.
The first blower 27 is mounted in a lower portion of the accommodation portion 21. The first blower 27 includes a fan (not shown) and a casing surrounding the fan. The fan of the first blower 27 faces the inside of the accommodation portion 21 through an opening (not shown) formed in the bottom surface 21e. An opening is provided in the casing of the first blower 27, and the duct 29 is coupled to the first blower 27 so that this opening is covered.
The first blower 27 sucks the air inside the accommodation portion 21 and exhausts the air to the duct 29. The duct 29 guides the exhaust air of the first blower 27 downward from the first deodorization mechanism 20. The air inside the housing 10 is sucked from the first intake port 25 according to an operation of the first blower 27. This air passes through the inside of the accommodation portion 21, passes through the first blower 27 and the duct 29, and is exhausted from a lower portion of the first deodorization mechanism 20. Since the inside of the housing 10 becomes under negative pressure by the air being exhausted, fresh air can be taken into the inside of the housing 10 from the outside of the housing 10.
As described above, the first deodorization mechanism 20 and the second deodorization mechanism 50 have a common configuration. For example, the second deodorization mechanism 50 includes the accommodation portion 51 corresponding to the accommodation portion 21, the lid portion 53 corresponding to the lid portion 23, the second blower 57 corresponding to the first blower 27, and the duct 59 corresponding to the duct 29. The accommodation portion 51 includes a front surface 51a, a side surface 51b, a side surface 51d, a rear surface 51c, and a bottom surface 51e, similar to the accommodation portion 21, and a second intake port 55 opens on the front surface 51a in an upper portion of the accommodation portion 51. The lid portion 53 includes a tip panel 53a, a base panel 53b, a hinge portion 53c, a concave portion 53d, and a support portion 53e, similar to the lid portion 23. These configurations correspond to the respective portions of the first deodorization mechanism 20, as illustrated in
The deodorization cartridge 40 is accommodated in the accommodation portion 51. The deodorization cartridge 40 is removably accommodated in the accommodation portion 51, and the deodorization cartridge 40 can be replaced. The deodorization cartridge 40 accommodated in the accommodation portion 51 and the deodorization cartridge 40 accommodated in the accommodation portion 21 can be the same. In other words, the deodorization cartridge 40 can be mounted on any one of the first deodorization mechanism 20 and the second deodorization mechanism 50.
The deodorization cartridge 40 includes a deodorization body cover 41. The deodorization body cover 41 includes an upper cover 42 that forms an upper surface of the deodorization body cover 41, and a cover body 43. The cover body 43 is a substantially box-shaped container. The deodorization body cover 41 corresponds to an accommodation body.
An opening (not shown) is formed at a bottom surface of the cover body 43. In the upper cover 42, an upper surface ventilation hole 42a opens. These openings allow ventilation between an internal space of the cover body 43 and the outside. The opening formed at the bottom surface of the cover body 43 and the upper surface ventilation hole 42a correspond to an opening portion.
A handle 44 is attached to the upper cover 42. The user can lift the deodorization cartridge 40 without touching a deodorization unit 47, by holding the handle 44.
In a state in which the deodorization cartridge 40 is accommodated in the first deodorization mechanism 20, air flowing into the accommodating portion 21 from the first intake port 25 is sent to the deodorization unit 47 through the upper surface ventilation hole 42a according to the operation of the first blower 27. This air passes through the deodorization unit 47, is then discharged from an opening provided on the bottom surface of the cover body 43, and flows to the first blower 27 through the bottom surface 21e.
The front surface 21a, the side surface 21b, the rear surface 21c, the side surface 21d, and the bottom surface 21e that constitute the accommodating portion 21 are made of a non-flammable or flame-retardant material. Similarly, the front surface 51a, the side surface 51b, the rear surface 51c, the side surface 51d, and the bottom surface 51e constituting the accommodation portion 51 are made of a non-flammable or flame-retardant material. When a combustible material such as activated carbon is used as the deodorization body, it is necessary to consider the risk of fire in the deodorization unit 47. In the recording device 1, since five surfaces of the accommodation portion 21 and the accommodation portion 51 are made of a non-flammable or flame-retardant material, it is possible to minimize risk of fire occurring in the deodorization unit 47. Therefore, a combustible material can be used as the deodorization unit 47. Therefore, a degree of freedom in selecting the deodorization unit 47 is high, and the deodorization unit 47 suitable for an ink that is an odor source is used so that deodorization can be performed efficiently.
In the first deodorization mechanism 20 and the second deodorization mechanism 50, the deodorization cartridge 40 is replaceable. That is, the user can remove the deodorization cartridge 40 mounted on the first deodorization mechanism 20 and set a new deodorization cartridge 40 in the first deodorization mechanism 20. When an operation of replacing the deodorization cartridge 40 is performed, the user can easily handle the deodorization cartridge 40 by holding the handle 44.
As illustrated in
Since an upper portion of the accommodation portion 21 is open in a state in which the lid portion 23 is open, the user can perform an operation of removing the deodorization cartridge 40 from the accommodation portion 21 and an operation of inserting the deodorization cartridge 40 into the accommodation portion 21. This allows the deodorization cartridge 40 to be easily replaced in the first deodorization mechanism 20 and the second deodorization mechanism 50.
When the deodorization cartridge 40 is inserted into the accommodation portion 21, the user holds the handle 44 and moves the deodorization cartridge 40 in a −Z-axis direction to insert the deodorization cartridge 40 into the accommodation portion 21. Further, when the deodorization cartridge 40 is removed from the accommodation portion 21, the user holds the handle 44 and moves the deodorization cartridge 40 in a +Z-axis direction to remove the deodorization cartridge 40 from the accommodation portion 21. The Z-axis direction corresponds to a detachment direction, the +Z-axis direction corresponds to a removal direction, and the −Z-axis direction corresponds to a mounting direction. In the operation of replacing the deodorization cartridge 40, the user can remove and mount the deodorization cartridge 40 by holding the handle 44 in their hand. Accordingly, replacement of the deodorization cartridge 40 becomes a simple task.
As illustrated in
Similarly, a second deodorization body sensor 58a and a second lid sensor 58b are disposed on the rear surface 51c of the second deodorization mechanism 50. The second deodorization body sensor 58a is a sensor that detects whether or not the deodorization cartridge 40 is accommodated in the accommodation portion 51. The second lid sensor 58b is a sensor that detects whether or not the lid portion 53 is closed.

The control unit 100 detects whether or not the lid portion 53 is closed based on a detection value of the second lid sensor 58b.
A configuration of the deodorization unit 47 accommodated in the accommodating portion 21 will be described with reference to
The activated carbon 101 corresponds to an example of a deodorization body, and for example, pelletized carbon is used. A shape of the pelletized carbon is arbitrary, but may be, for example, a cylindrical shape.
The activated carbon 101 is accommodated in the bag member 103. For example, nonwoven fabric is used for the bag member 103.
The bag member 103 accommodating the activated carbon 101 is fixed at upper and lower locations in the Z-axis direction by the urethanes 105A and 105B within the accommodation portion 21. The Z-axis direction also corresponds to a ventilation direction within the deodorization cartridge 40. The ventilation direction is a direction in which the air inside the deodorization body cover 41 sucked by the first blower 27 moves. The urethane 105A is disposed on an upper side in the Z-axis direction, that is, an upper portion of the bag member 103, and the urethane 105B is disposed on a lower side in the Z-axis direction, that is, a lower portion of the bag member 103. The Z-axis direction corresponds to a first direction. The upper side in the Z-axis direction corresponds to one side in the first direction, and the lower side in the Z-axis direction corresponds to the other side in the first direction. The urethane 105A contacts and fixes the bag member 103 accommodating the activated carbon 101 from an upward direction, and the urethane 105A contacts and fixes the bag member 103 accommodating the activated carbon 101 from the downward direction.
The activated carbon 101 accommodated in the nonwoven bag member 103 generates a large amount of fine powder due to friction between the nonwoven fabric and the activated carbon 101. The activated carbon 101 is fixed by the upper urethane 105A and the lower urethane 105B so that the movement of the activated carbon 101 inside the bag member 103 is curbed, the friction is reduced, and the generation of the fine powder of the activated carbon 101 is reduced.
The urethanes 105A and 105B are accommodated in the accommodation portion 21 while being elastically deformed so that the urethanes 105A and 105B are crushed. Accordingly, a movement of the activated carbon 101 sandwiched from an up-down direction by the urethanes 105A and 105B due to vibration can be curbed, and powder falling from the activated carbon 101 can be reduced.
In the present embodiment, an example in which the urethanes 105A and 105B are disposed above and below the bag member 103 accommodating the activated carbon 101 is shown. The disposition of the urethanes 105A and 105B is not limited to locations on and beneath the bag member 103, and may be disposed in at least one of the left-right direction in the X-axis direction and the front-rear direction in the Y-axis direction in a state in which the deodorization cartridge 40 is accommodated in the accommodation portion 21 of the first deodorization mechanism 20.
The nonwoven fabric sheet 107A is disposed on the urethane 105A in the Z-axis direction, and the nonwoven fabric sheet 107B is disposed beneath the urethane 105B in the Z-axis direction.
The nonwoven fabric sheet 107A has a function of adsorbing ink mist that flows into the accommodation portion 21 according to a blowing operation of the first blower 27. When the ink mist enters the accommodation portion 21, a deodorizing effect of the activated carbon 101 may be greatly degraded, and thus, the ink mist flowing into the accommodation portion 21 is adsorbed by the nonwoven fabric sheet 107A.
The nonwoven fabric sheet 107B has a function of absorbing fine powder of the activated carbon 101 and preventing the fine powder from leaking to the outside. The nonwoven fabric sheet 107B is disposed downstream in the ventilation direction of the bag member 103 that accommodates the activated carbon 101.
The air flowing into the accommodation portion 21 from the first intake port 25 is sent to the deodorization unit 47 through the upper surface ventilation hole 42a according to the blowing operation of the first blower 27. In this case, it is possible to prevent fine powder of the activated carbon 101 from leaking from an opening formed in the bottom surface of the cover body 43 to the outside by providing the nonwoven fabric sheet 107B downstream in the ventilation direction.
