Description

Technical Field

[0001] The invention relates to a dishwashing machine. Background Art

[0002] Japanese Patent Publication No. 2021-132978 discloses a conventional dishwashing machine. The dishwashing machine includes a washing tank, a cover, a storage tank, a treatment agent supply device, and a treatment agent supply path. The washing tank has a tank opening that is open at the top. The cover can open and close the tank opening. The cover and the washing tank form a cleaning space for washing the objects to be washed with cleaning water. In addition, a storage section for storing the storage tank is formed in the washing tank. The storage section is located outside the cleaning space, that is, in front of the cleaning space.

[0003] The storage tank stores the treatment agent for the object to be cleaned. The treatment agent supply device is installed in the cleaning tank and is located outside the cleaning space. The treatment agent supply device supplies the treatment agent stored in the storage tank into the cleaning space. The treatment agent supply path is installed in the cleaning tank and is located outside the cleaning space. It is connected to the treatment agent supply path. In addition, the treatment agent supply path has a supply path side connection part, and the storage tank is installed in a manner that can be loaded and unloaded relative to the supply path side connection part.

[0004] In the dishwasher, the storage tank is stored in the storage section and is mounted on the supply path side connection section. Thus, the storage tank is arranged outside the washing space and is connected to the treatment agent supply device through the treatment agent supply path. In this way, the treatment agent in the storage tank flows through the treatment agent supply device. On the other hand, the storage tank is removed from the supply path side connection section by pulling the storage tank out from the storage section. Accordingly, in the dishwasher, the storage tank can be taken out from the storage section, so that the treatment agent can be replenished in the storage tank outside the dishwasher.

[0005] In the above-mentioned conventional dishwasher, when the treatment agent is added to the storage tank, part of the treatment agent may adhere to the surface of the storage tank, or when the supply road side connection part and the storage tank are loaded and unloaded, the treatment agent in the storage tank may leak out. In addition, such treatment agent adheres to the supply road side connection part and gradually accumulates on the supply road side connection part. Therefore, in the dishwasher, the accumulated treatment agent causes the supply road side connection part and the storage tank to be fixed and bonded, and the loading and unloading properties of the supply road side connection part and the storage tank may be impaired.

[0006] Therefore, the user of the dishwasher needs to regularly remove the treatment agent accumulated in the storage section or the supply path side connection section, but the storage section and the supply path side connection section are located outside the washing space, so it is difficult for the user to remove the treatment agent. Summary of the invention

[0007] Therefore, a non-limiting object of the present invention is to provide a dishwasher having a structure with a storage tank for storing a treatment agent and having excellent loading and unloading properties of the storage tank. This object is solved by the invention of claim 1. Further developments of the present invention are described in the dependent claims.

[0008] The dishwasher of the present invention comprises:

[0009] a cleaning tank having a tank opening opened toward one side;

[0010] a cover body, which can open and close the tank opening and, together with the cleaning tank, forms a cleaning space for cleaning objects with cleaning water;

[0011] A storage tank for storing a treatment agent for the object to be cleaned;

[0012] a treatment agent supply device, located outside the cleaning space, for supplying the treatment agent stored in the storage tank into the cleaning space; and

[0013] a treatment agent supply path connecting the storage tank and the treatment agent supply device,

[0014] The cleaning tank or the cover has a specific wall facing the cleaning space,

[0015] The treatment agent supply path is fixed to the specific wall in a state facing the cleaning space, and has a supply path side connection portion to which the storage tank is detachably mounted.

[0016] The storage tank is mounted on the supply path side connection portion and is arranged in the cleaning space.

[0017] In the dishwasher of the present invention, the treatment agent supply path has a supply path side connection portion fixed to a specific wall facing the washing space, and the storage tank is mounted on the supply path side connection portion so that the storage tank is arranged in the washing space.

[0018] According to this, in the dishwasher, even if the treatment agent attached to the surface of the storage tank during the replenishment of the treatment agent is attached to the supply road side connection part via the storage tank, or the treatment agent inevitably leaked during the loading and unloading of the storage tank and the supply road side connection part is attached to the supply road side connection part, such treatment agent can be removed from the surface of the storage tank and the supply road side connection part by the washing water in the washing space. In addition, even if the treatment agent cannot be completely removed by washing water, since the storage tank is arranged in the washing space, the user can remove the treatment agent attached to the surface of the storage tank and the supply road side connection part.

[0019] As a result, in this dishwasher, the treatment agent is less likely to accumulate on the supply path side connection portion, and thus it is possible to suppress the supply path side connection portion and the storage tank from being fixed and bonded due to the treatment agent.

[0020] Therefore, according to the structure of the dishwasher of the present invention having the storage tank for storing the treatment agent, the storage tank is excellent in attachment and detachability.

[0021] In another embodiment of the present invention, preferably, the storage tank comprises: a tank body, which stores the treatment agent; a first tank side connection portion, which is connected to the tank body and is installed on the supply path side connection portion in a loadable and detachable manner; and a second tank side connection portion, which is located above the first tank side connection portion and enables communication between the outside of the cleaning space and the inside of the tank body.

[0022] In this case, the outside of the cleaning space and the inside of the tank body are connected through the second tank side connection part, thereby preventing the inside of the tank body from becoming negative pressure. Therefore, the treatment agent in the tank body can be properly circulated in the treatment agent supply path and even the treatment agent supply device.

[0023] In another embodiment of the present invention, a vent can be provided on the specific wall, the vent is fixed in a state facing the cleaning space and communicates with the outside of the cleaning space, and the second tank side connection part is installed in a detachable manner. Preferably, the first tank side connection part and the second tank side connection part extend parallel to each other toward the specific wall.

[0024] According to this, the first tank-side connection portion can be easily attached and detached to and from the supply path-side connection portion, and the second tank-side connection portion can be easily attached and detached to and from the vent portion.

[0025] In addition, the dishwasher of the present invention preferably includes, in another aspect of the present invention, a determination mechanism capable of determining whether the storage tank is attached to the supply path side connection portion, and a notification mechanism for notifying a determination result of the determination mechanism.

[0026] In this case, the user can easily know whether the storage tank is installed on the supply road side connection part through the notification of the notification means. Here, the notification means may only notify that the storage tank is installed on the supply road side connection part based on the judgment result of the judgment means, or may only notify that the storage tank is not installed on the supply road side connection part. In addition, the notification means may separately notify that the storage tank is installed on the supply road side connection part and notify that the storage tank is not installed on the supply road side connection part.

[0027] In another embodiment of the present invention, a remaining amount monitoring mechanism may be provided to monitor the remaining amount of the treatment agent stored in the storage tank. Preferably, the judging mechanism judges that the storage tank is not installed on the supply road side connection portion when the remaining amount monitoring mechanism does not monitor the remaining amount.

[0028] In this case, when the determination means determines whether the storage tank is attached to the supply path side connection portion, there is no need to use a dedicated monitoring device or the like. Therefore, the structure of the dishwasher can be simplified.

[0029] In another aspect of the present invention, a water storage portion may be formed in the washing tank, the water storage portion being communicated with the washing space and storing washing water. In addition, preferably, the storage tank is mounted on the supply path side connection portion and is located above the water storage portion.

[0030] In this case, the storage tank can be prevented from being immersed in the washing water stored in the water storage portion. According to this, in the dishwasher, the washing water is unlikely to enter the storage tank.

[0031] In addition, regarding the dishwasher of the present invention, in another embodiment of the present invention, a loading member may be provided, the loading member being used to load the objects to be washed and being stored in the washing space. And, preferably, the loading member has an interference portion, which interferes with the storage tank when the storage tank is not completely installed with respect to the connection portion on the supply path side.

[0032] In this case, the interference portion interferes with the storage tank, so that the user can easily know that the storage tank is attached to the supply road side connection portion in an incomplete state.

[0033] In another aspect of the present invention, preferably, the cleaning tank has a specific wall. In this case, the structure of the cover can be simplified.

[0034] In addition, in this case, regarding the dishwashing machine of the present invention, in another embodiment of the present invention, a housing may be provided, the housing having a housing opening that opens toward the front, and the washing tank can be arranged inside. The tank opening can be opened toward the front and communicate with the housing opening. And, preferably, the cover is mounted on the housing in a manner that can swing in the front-to-back direction around the swing axis, and is shifted between an open position in which the housing opening and the tank opening are opened and a closed position in which the housing opening and the tank opening are closed.

[0035] In this case, a so-called front-opening dishwasher can be realized. In addition, although the cover body is displaced between the open position and the closed position, the washing tank has a specific wall, so that the supply path side connection part and even the storage tank are not provided on the cover body. Therefore, it is difficult for the treatment agent to leak from the storage tank due to the displacement of the cover body.

[0036] Other aspects and advantages of the present invention will become apparent from the embodiments disclosed in the following description and the drawings, the diagrams shown as examples in the drawings, and the concept of the present invention disclosed in the specification and the drawings as a whole.

The first cutlery basket 13 is an example of a "loading component" in the present invention. In addition, the operating unit 19 is an example of a "notification mechanism" in the present invention. And, the control unit 21 is an example of a "judgment mechanism" in the present invention. The dishwashing machine is assembled in an integrated kitchen not shown in the figure. It should be noted that for ease of explanation, Figure 2 The cover 5 and the first cutlery basket 13 are omitted. Figure 3 The housing 1, the cover 5, etc. are omitted in the figure.

[0050] In this embodiment, using Figure 1 and Figure 2 The arrows shown define the front-rear direction and the up-down direction of the dishwasher. Figure 2 In the table, the right side of the user (not shown) is set as the right side of the dishwasher and the left side of the user is set as the left side of the dishwasher, with the user's right side as the right side of the dishwasher and the user's left side as the left side of the dishwasher, thereby defining the left-right direction, i.e., the width direction of the dishwasher. The front-to-back direction, the up-down direction, and the left-to-right direction are mutually orthogonal. Figure 3 In the following figures, Figure 1 and Figure 2 The front-rear direction, the up-down direction, and the left-right direction of the dishwasher are defined accordingly.

[0051] like Figure 1 and Figure 2As shown, the housing 1 has a right side panel 1a, a left side panel 1b, a front lower panel 1c, a rear lower panel 1d, a bottom panel 1e and a housing opening 1f. The right side panel 1a and the left side panel 1b are formed into approximately rectangular plates extending in the front-to-back direction and the up-down direction, respectively. The right side panel 1a and the left side panel 1b are respectively configured to be isolated in the left-right direction. Thus, the right side panel 1a constitutes the right side of the housing 1, and the left side panel 1b constitutes the left side of the housing 1.

[0052] The front lower panel 1c and the rear lower panel 1d are formed into a substantially rectangular plate extending in the up-down direction and the left-right direction. The front lower panel 1c and the rear lower panel 1d are respectively mounted on the right side panel 1a and the left side panel 1b and are arranged between the right side panel 1a and the left side panel 1b. More specifically, the front lower panel 1c is arranged between the right side panel 1a and the left side panel 1b, and is arranged at the front lower portion of the right side panel 1a and the left side panel 1b. On the other hand, the rear lower panel 1d is arranged between the right side panel 1a and the left side panel 1b, and is arranged at the rear lower portion of the right side panel 1a and the left side panel 1b. That is, the front lower panel 1c and the rear lower panel 1d are arranged to be isolated in the front-back direction between the right side panel 1a and the left side panel 1b.

[0053] The bottom panel 1e is formed in a substantially rectangular plate shape extending in the front-rear direction and the left-right direction. The bottom panel 1e is arranged at the bottom of the housing 1 and is mounted on the lower ends of the right side panel 1a, the left side panel 1b, the front lower panel 1c and the rear lower panel 1d. The right side panel 1a, the left side panel 1b, the front lower panel 1c, the rear lower panel 1d and the bottom panel 1e form a storage space 10 at the bottom of the housing 1.

[0054] The housing opening 1f is formed between the right side panel 1a, the left side panel 1b, and the front lower panel 1c. Thus, the housing opening 1f is located above the storage space 10 and opens toward the front of the housing 1.

[0055] like Figure 2 As shown, the cleaning tank 3 has a right side wall 3a, a left side wall 3b, a rear wall 3c, an upper wall 3d, a lower wall 3e and a tank opening 3f. The right side wall 3a constitutes the right side of the cleaning tank 3 and extends in the front-to-back direction and the up-down direction. The right side wall 3a is an example of the "specific wall" in the present invention. The left side wall 3b constitutes the left side of the cleaning tank 3 and extends in the front-to-back direction and the up-down direction. The right side wall 3a and the left side wall 3b are opposite in the left-right direction.

[0056] The rear wall 3c constitutes the rear surface of the cleaning tank 3 and extends in the left-right direction and the up-down direction. The rear wall 3c is arranged between the right side wall 3a and the left side wall 3b, and is connected to each rear end of the right side wall 3a and the left side wall 3b. The upper wall 3d constitutes the upper surface of the cleaning tank 3 and extends in the left-right direction and the front-back direction. The upper wall 3d is arranged between the right side wall 3a, the left side wall 3b and the rear wall 3c, and is connected to each upper end of the right side wall 3a, the left side wall 3b and the rear wall 3c. The lower wall 3e constitutes the lower surface of the cleaning tank 3 and extends in the left-right direction and the front-back direction. The lower wall 3e is arranged between the right side wall 3a, the left side wall 3b and the rear wall 3c, and is connected to each lower end of the right side wall 3a, the left side wall 3b and the rear wall 3c. Thus, the upper wall 3d and the lower wall 3e are opposite in the up-down direction.

[0057] like Figure 1 As shown in FIG. 1 , a water storage portion 23 is formed on the lower wall 3e. More specifically, the water storage portion 23 is formed by making a portion of the lower wall 3e substantially in the center in the front-back direction and the left-right direction concave downward. Washing water is stored in the water storage portion 23. In addition, although detailed illustration is omitted, an opening penetrating in the up-down direction is formed in the center of the water storage portion 23. It should be noted that the details of the washing water will be described below.

[0058] The slot opening 3f is located at the front end of the cleaning tank 3. The slot opening 3f opens toward the front of the cleaning tank 3 so that the inside and outside of the cleaning tank 3 are connected in the front-to-back direction. The cleaning tank 3 is formed into a substantially rectangular box shape with an opening at the front by the right side wall 3a, the left side wall 3b, the rear wall 3c, the upper wall 3d, the lower wall 3e and the slot opening 3f.

[0059] In addition, if Figure 2 As shown, a first lower guide member 111, a first middle guide member 112, and a first upper guide member 113 are installed on the right side wall 3a. The first lower guide member 111 is installed at the lower portion of the right side wall 3a. The first middle guide member 112 is installed on the right side wall 3a at a position further upward than the first lower guide member 111. The first upper guide member 113 is installed on the right side wall 3a at a position further upward than the first middle guide member 112. The first lower guide member 111, the first middle guide member 112, and the first upper guide member 113 extend parallel to the front-rear direction along the right side wall 3a, respectively.

[0060] On the other hand, the second lower guide member 114, the second middle guide member 115, and the second upper guide member 116 are installed on the left side wall 3b. The second lower guide member 114 is installed on the left side wall 3b in a manner that is equal to the height of the first lower guide member 111. The second middle guide member 115 is installed on the left side wall 3b in a manner that is equal to the height of the first middle guide member 112. The second upper guide member 116 is installed on the left side wall 3b in a manner that is equal to the height of the first upper guide member 113. In addition, the second lower guide member 114, the second middle guide member 115, and the second upper guide member 116 extend in the front-rear direction along the left side wall 3b and in parallel with the first lower guide member 111, the first middle guide member 112, and the first upper guide member 113, respectively.

[0061] Thus, inside the cleaning tank 3, the first and second lower guide members 111, 114 are opposite to each other in the left-right direction, the first and second middle guide members 112, 115 are opposite to each other in the left-right direction, and the first and second upper guide members 113, 116 are opposite to each other in the left-right direction.

[0062] In addition, if Figure 1 and Figure 4 As shown, the supply path side connection part 35 and the ventilation part 37 are fixed to the right side wall 3a between the first lower guide member 111 and the first middle guide member 112.

The lower end of the connecting cylinder 25a is connected to the water distributor 26. In addition, a first spray nozzle 31 is rotatably mounted on the upper end of the connecting cylinder 25a. Thus, the first spray nozzle 31 is arranged inside the cleaning tank 3. The first spray nozzle 31 can rotate inside the cleaning tank 3. In addition, a plurality of spray parts 300 are formed in the first spray nozzle 31.

[0067] In addition, if Figure 1 As shown, a water supply hose 41, a water supply pump 43, and a drainage pump 45 are connected to the water storage tank 25. The water supply pump 43 and the drainage pump 45 are respectively arranged in the storage space 10 and located below the washing tank 3.

[0068] One end of the water supply hose 41 is connected to the water storage tank 25. In addition, the other end of the water supply hose 41 extends to the outside of the housing 1 and is connected to a water supply source (not shown) provided outside the dishwasher. Thus, the water supply hose 41 connects the water storage tank 25 and the water supply source. The water supply pump 43 and the drainage pump 45 are respectively connected to the control unit 21 in a manner that allows electricity to be supplied. In addition, a water supply solenoid valve (not shown) is provided in the water supply hose 41. It should be noted that the specific operations of the water supply pump 43 and the drainage pump 45 are described below.

[0069] In addition, one end of the drain hose 47 is connected to the water storage tank 25. In addition, the other end of the drain hose 47 extends to the outside of the housing 1 and is connected to a drain port (not shown) provided outside the dishwasher. Thus, the drain hose 47 connects the water storage tank 25 and the drain port. In addition, a drain solenoid valve (not shown) is provided in the drain hose 47.

[0070] The water distributor 26 is disposed in the storage space 10 and assembled to the water storage tank 25. The water distributor 26 is fixed to the lower wall 3e of the washing tank 3 together with the water storage tank 25. In addition, the water distributor 26 is connected to the water supply pump 43.

[0071] like Figure 1 and Figure 2As shown, the water supply pipe 27 is arranged inside the washing tank 3. Washing water can flow inside the water supply pipe 27. The water supply pipe 27 is composed of a first pipe 27a, a second pipe 27b, a third pipe 27c and a branch pipe 27d. The first pipe 27a is located above the lower wall 3e and extends in the front-to-back direction along the lower wall 3e. The front end of the first pipe 27a is connected to the water distributor 26 at a position different from the connecting cylinder 25a.

[0072] The second pipe 27b is fixed to the rear wall 3c and extends in the vertical direction along the rear wall 3c in the washing tank 3. The lower end of the second pipe 27b is connected to the rear end of the first pipe 27a. The third pipe 27c extends in the front-rear direction along the upper wall 3d in the washing tank 3. The rear end of the third pipe 27c is connected to the upper end of the first pipe 27a. The branch pipe 27d is connected to the second pipe 27b at a position approximately in the center of the second pipe 27b in the vertical direction, and extends from the second pipe 27b toward the front.

[0073] In addition, the second injection nozzle 32 is rotatably connected to the front end of the branch pipe 27d, and the third injection nozzle 33 is rotatably connected to the front end of the third pipe 27c. At this time, the second injection nozzle 32 and the third injection nozzle 33 are connected from below with respect to the front end of the branch pipe 27d and the front end of the third pipe 27c, respectively. In addition, similarly to the first injection nozzle 31, a plurality of injection parts 300 are formed for the second and third injection nozzles 32 and 33.

[0074] The air circulation device 28 is configured to include the ventilation portion 37, Figure 1 and Figure 3 The ventilation duct 28a shown, Figure 3 The connecting hose 28b shown, Figure 1 The air supply fan 28c is shown as well as Figure 2 The air supply unit 28d is shown. Figure 3 As shown, the ventilation duct 28a is installed on the right side wall 3a of the cleaning tank 3 and is located between the right side wall 3a and the right side panel 1a of the housing 1. That is, the ventilation duct 28a is installed on the opposite side of the first lower guide member 111, the first middle guide member 112 and the first upper guide member 113 on the right side wall 3a, and is located outside the cleaning tank 3. The ventilation duct 28a is connected to the ventilation part 37. Thus, the ventilation duct 28a is connected to the first vent 37a and each second vent 37b of the ventilation part 37. The ventilation duct 28a bends and extends from the connection part with the ventilation part 37 toward the upper rear part, and then extends in a straight line toward the bottom of the right side wall 3a.

[0077] The filter unit 29 includes a first filter portion 29a and a second filter portion 29b. The first filter portion 29a is placed on the lower wall 3e of the washing tank 3 and covers the water storage portion 23 from above. The second filter portion 29b is inserted through the first filter portion 29a and extends into the water storage portion 23 and the water storage tank 25. The filter unit 29 can capture residues such as leftovers contained in the washing water by using the first filter portion 29a and the second filter portion 29b.

[0078] The locking device 50 is fixed to the upper wall 3d of the washing tank 3. Thus, the locking device 50 is located above the tank opening 3f and is located substantially in the center of the washing tank 3 in the left-right direction.

[0079] like Figure 1 As shown, the cover body 5 has an outer panel 5a and an inner panel 5b. The outer panel 5a is formed by a plate extending in the up-down direction and the left-right direction. A gripping portion 5c is fixed to the upper portion of the outer panel 5a. The inner panel 5b is fixed to the rear of the outer panel 5a.

[0080] The cover 5 is mounted on the front of the housing 1 by means of a hinge mechanism 51 and a damping mechanism (not shown) provided in the storage space 10. Thus, the cover 5 can swing in the front-rear direction around the first swing axis O1 relative to the housing 1. The first swing axis O1 is an example of the "swing axis" in the present invention. The first swing axis O1 extends in a straight line along the left-right direction of the housing 1.

[0081] The cover 5 is displaced to the position where the cover 5 is swung backward around the first swing axis O1. Figure 1 The cover 5 is in the closed position shown by the solid line in FIG. The cover 5 closes the housing opening 1f and the tank opening 3f from the front by shifting to the closed position. Moreover, the cover 5 shifted to the closed position forms a cleaning space 100 together with the cleaning tank 3. That is, the cleaning space 100 is formed between the right side wall 3a, the left side wall 3b, the rear wall 3c, the upper wall 3d and the lower wall 3e of the cleaning tank 3 and the inner side panel 5b of the cover 5.

[0082] In addition, the ventilation portion 37 (see Figure 4 ) faces the cleaning space 100. Thus, the first vent 37a and each second vent 37b of the ventilation portion 37 connect the cleaning space 100 and the ventilation duct 28a, thereby connecting the cleaning space 100 with the inside of the ventilation duct 28a, that is, the outside of the cleaning space 100. In addition, Figure 1 The locking device 50 shown holds the cover body 5 in the closed position by locking the cover body 5 displaced to the closed position.

[0083] On the other hand, the cover 5 is displaced to the position by swinging forward around the first swing axis O1. Figure 1 The cover 5 is shifted to the open position so that the housing opening 1f and the slot opening 3f are opened forward. It should be noted that, in this dishwasher, even if the cover 5 is shifted to the open position, the washing tank 3 does not move in the front-rear direction relative to the housing 1, but remains in the housing 1.

[0084] like Figure 5 As shown, the storage tank 7 has a tank body 71, a cover 73, a first tank side connection portion 75, and a second tank side connection portion 77. Figure 6 As shown, the tank body 71 is formed in a substantially rectangular box shape with an open top. The tank body 71 can store a liquid treatment agent 200 inside. Specifically, the treatment agent 200 is a dishwashing agent.

[0085] In addition, an engaging protrusion 71a is formed at the front of the tank body 71. The engaging protrusion 71a protrudes forward from the tank body 71. In addition, a pair of legs 71b are provided at the lower part of the tank body 71. When the storage tank 7 is placed on the ceiling or table of the kitchen, the legs 71b maintain the storage tank 7 including the tank body 71 in a horizontal posture.

[0086] The cover 73 is mounted on the upper part of the tank body 71 and can swing in the vertical direction around the second swing axis O2 relative to the tank body 71. Figure 6 The upper part of the tank body 71 is covered by the first position shown by the solid line in FIG. 1 and the upper part of the tank body 71 is closed. On the other hand, the cover 73 is swung to the first position shown by the solid line in FIG. Figure 6 The upper portion of the tank body 71 is opened by changing the second position shown by the virtual line in FIG.

[0087] The cover 73 is formed with a ventilation communication port 73a and an engaging claw portion 73b. The ventilation communication port 73a passes through the cover 73 in the up-down direction and communicates with the inside of the second tank side connection portion 77. The engaging claw portion 73b is formed at the front of the cover 73 and extends toward the engaging protrusion 71a. When the cover 73 swings to the first position, the engaging claw portion 73b engages with the engaging protrusion 71a, thereby maintaining the cover 73 in the first position.

[0088] In addition, a float device 8 is provided on the cover body 73. The float device 8 and the control unit 21 together constitute the "remaining amount monitoring mechanism" in the present invention. The float device 8 has a float body 8a and a float arm 8b. The float body 8a is formed in a rectangular box shape with a hollow interior. In addition, although not shown in the figure, an air chamber is formed inside the float body 8a, and a plurality of magnets are also provided. The float arm 8b is connected to the float body 8a and extends toward the cover body 73. In addition, the float arm 8b is connected to the cover body 73 in a manner that it can swing around the third swing axis O3.

[0089] The float device 8 is disposed in the tank body 71 with the cover 73 in the first position. The float device 8 can swing in the front-rear direction around the third swing axis O3 according to the storage amount of the treatment agent 200 in the tank body 71.

[0090] like Figure 7 and Figure 8 As shown, the first tank side connection part 75 is formed integrally with the tank body 71. More specifically, the first tank side connection part 75 extends in a substantially cylindrical shape from the lower right portion of the tank body 71 toward the right side of the tank body 71, that is, the right side wall 3a of the washing tank 3. The first tank side connection part 75 is connected to the inside of the tank body 71.

[0091] An O-ring 75a is provided on the outer peripheral surface of the first tank side connection part 75. In addition, a valve mechanism 12 is provided inside the first tank side connection part 75. The valve mechanism 12 has a valve housing 12a, a valve body 12b, a coil spring 12c, and a treatment agent filter 12d. A valve opening 121 and a communication port 122 are formed in the valve housing 12a, and a seat portion 123 is also formed. The valve opening 121 and the communication port 122 penetrate the valve housing 12a in the left-right direction, respectively. It should be noted that Figure 5 The O-ring 75a is omitted in the figure.

[0092] like Figure 7 and Figure 8 As shown in FIG. 1 , the valve body 12b is disposed in the valve housing 12a and is opposed to the valve opening 121 from the left side. The coil spring 12c is disposed between the seat 123 and the valve body 12b in the valve housing 12a. Figure 7As shown, the coil spring 12 c urges the valve body 12 b toward the valve opening 121 , so that the valve body 12 b closes the valve opening 121 .

[0093] The treatment agent filter 12d is attached to the left end of the valve housing 12a and is inserted into the tank body 71. A plurality of fine holes 124 are formed in the treatment agent filter 12d. The treatment agent filter 12d captures the treatment agent 200 (see Figure 6 ) and allows the processing agent 200 to flow toward the communication port 122 of the valve housing 12a.

[0094] The second tank side connection part 77 is formed integrally with the cover body 73. More specifically, the second tank side connection part 77 protrudes upward from the cover body 73 and extends toward the right side of the cover body 73, that is, the right side wall 3a of the washing tank 3. Here, the first tank side connection part 75 and the second tank side connection part 77 extend in parallel toward the right side wall 3a.

[0095] The second tank side connection part 77 is formed into a bottomed cylindrical shape with an open right end and a closed left end. In addition, air can flow inside the second tank side connection part 77. And, the second tank side connection part 77 is communicated with the ventilation communication port 73a of the cover body 73. Thus, the cover body 73 is in the first position so that the second tank side connection part 77 is communicated with the tank body 71 through the ventilation communication port 73a. In addition, a detachment prevention part 77a is formed at the right end of the second tank side connection part 77.

[0096] Regarding the storage tank 7, the first tank side connection portion 75 can be attached and detached with respect to the supply path side connection portion 35, and the second tank side connection portion 77 can be attached and detached with respect to the ventilation portion 37. Figure 1 and Figure 8 As shown, the storage tank 7 is arranged in the cleaning space 100 by installing the first tank side connection part 75 and the second tank side connection part 77 on the supply path side connection part 35 and the vent part 37, respectively. It should be noted that the attachment and detachment of the first tank side connection part 75 relative to the supply path side connection part 35 and the attachment and detachment of the second tank side connection part 77 relative to the vent part 37 will be described in detail below.

[0097] like Figure 3 As shown, the treatment agent supply device 9 is installed at the lower part of the right side wall 3a of the cleaning tank 3 and is located between the right side wall 3a and the right side panel 1a of the housing 1. Thus, the treatment agent supply device 9 is arranged outside the cleaning tank 3 and even outside the cleaning space 100.

[0098] The treatment agent supply device 9 includes a supply device body 9a and a treatment agent supply port 9b. The supply device body 9a is provided with a pump (not shown) inside. The supply device body 9a is electrically connected to the supply device body 9a. Figure 1 The control unit 21 shown is connected.

[0099] The processing agent supply port 9 b is located behind the supply device body 9 a and connected to the supply device body 9 a. The processing agent supply port 9 b is fixed to the lower portion of the right side wall 3 a and faces the inside of the cleaning space 100 .

[0100] The treatment agent supply path 11 includes a supply path main body 34 and a supply path side connection portion 35. The supply path main body 34 is located between the right side wall 3a and the right side panel 1a, and extends in the up-down direction. The treatment agent 200 can flow inside the supply path main body 34. In addition, the lower end of the supply path main body 34 is set as a device connection portion 34a. The supply path main body 34 is connected to the supply device main body 9a of the treatment agent supply device 9 through the device connection portion 34a.

[0101] The supply path side connection part 35 is connected to the upper end of the supply path main body 34. In addition, as described above, the supply path side connection part 35 is fixed to the right side wall 3a. Figure 7 and Figure 8 As shown, a connection opening 35a and a pressing protrusion 35b are formed in the supply path side connection part 35. The supply path side connection part 35 is fixed to the right side wall 3a so that the connection opening 35a faces the inside of the cleaning space 100. Thus, the connection opening 35a connects the cleaning space 100 and the supply path main body 34. The first tank side connection part 75 of the storage tank 7 can enter the inside of the connection opening 35a. The pressing protrusion 35b is located in the connection opening 35a and extends from the right side to the left side in the connection opening 35a.

[0102] Figure 1 The first cutlery basket 13, the second cutlery basket 14, and the third cutlery basket 15 shown can carry objects to be washed (not shown). The first cutlery basket 13, the second cutlery basket 14, and the third cutlery basket 15 classify the objects to be washed according to the types of the objects to be washed. In addition, the first cutlery basket 13 is formed to mainly carry large objects to be washed. It should be noted that the objects to be washed include, for example, tableware such as plates and bowls; eating utensils such as chopsticks and cups; and cooking containers such as pots.

[0103] The first cutlery basket 13 consists of Figure 2The first lower guide member 111 and the second lower guide member 114 shown are guided in the front-to-back direction and can enter and exit the washing space 100, and can be stored in the washing space 100 in a horizontal posture in the front-to-back direction and the left-to-right direction by the first lower guide member 111 and the second lower guide member 114. Similarly, the second cutlery basket 14 is guided in the front-to-back direction by the first middle guide member 112 and the second middle guide member 115 and can enter and exit the washing space 100, and can be stored in the washing space 100 in a horizontal posture in the front-to-back direction and the left-to-right direction by the first middle guide member 112 and the second middle guide member 115. Moreover, the third cutlery basket 15 is guided in the front-to-back direction by the first upper guide member 113 and the second upper guide member 116 and can enter and exit the washing space 100, and can be stored in the washing space 100 in a horizontal posture in the front-to-back direction and the left-to-right direction by the first upper guide member 113 and the second upper guide member 116.

[0104] In this way, in the washing space 100, the first cutlery basket 13, the second cutlery basket 14 and the third cutlery basket 15 are sequentially arranged from the bottom to the top.

[0105] In addition, if Fig. 9 As shown, the first cutlery basket 13 has a handle portion 13a and an interference portion 13b. The handle portion 13a is provided at the front of the first cutlery basket 13. When the first cutlery basket 13 is moved in and out of the washing space 100, the user can hold the handle portion 13a.

[0106] The interference portion 13b is provided at the right front portion of the first cutlery basket 13. The interference portion 13b extends from the right portion of the first cutlery basket 13 to the left side, and then extends upward from the first cutlery basket 13. The interference portion 13b is formed to oppose the storage tank 7 from the left side when the first cutlery basket 13 is stored in the washing space 100 with the storage tank 7 arranged in the washing space 100.

[0107] like Figure 1 As shown, the operation unit 19 is provided on the cover body 5 and is arranged on the upper part of the inner panel 5b. The operation unit 19 is connected to the control unit 21 in a manner that it can be powered. In addition, the operation unit 19 has a warning light 19a, and also has an operation button and a display that are not shown. The operation unit 19 can operate the dishwasher by operating the buttons. In addition, regarding the operation unit 19, the operating time of the dishwasher is displayed on the display, and in addition, the remaining amount of the treatment agent 200 stored in the tank body 71 of the storage tank 7 is also displayed.

[0108] In addition, when the storage tank 7 is not attached to the supply road side connection part 35 and the vent part 37, the operation part 19 notifies the user of this fact. Specifically, regarding the operation part 19, when the storage tank 7 is not attached to the supply road side connection part 35 and the vent part 37, the warning light 19a is lit. It should be noted that the operation part 19 may also be arranged on the outer panel 5a.

[0109] The control unit 21 is provided on the cover body 5 and is disposed between the outer panel 5a and the inner panel 5b. The control unit 21 controls the operation of the water supply pump 43, the drainage pump 45, the water supply solenoid valve, the drainage solenoid valve, the air supply fan 28c and the supply device body 9a. Thus, the control unit 21 performs the washing operation, the rinsing operation and the drying operation. It should be noted that the control unit 21 can also be disposed in the storage space 10.

[0110] In addition, the control unit 21 monitors the remaining amount of the treatment agent 200 stored in the tank body 71 based on the change in the magnetic force of the magnet of the float device 8. When the control unit 21 does not monitor the remaining amount of the treatment agent 200, it determines that the storage tank 7 is not attached to the supply path side connection part 35 and the ventilation part 37. Therefore, the control unit 21 controls the operation unit 19 to light the warning lamp 19a in the above-mentioned manner.

[0111] In the dishwasher constructed as described above, when the storage tank 7 storing the treatment agent 200 is mounted on the supply path side connection portion 35 and the vent portion 37, the user swings the cover 5 to the open position to open the housing opening 1f and the tank opening 3f forward. Then, the user inserts the storage tank 7 into the interior of the washing tank 3, that is, the washing space 100, as shown in FIG. Figure 7 As shown, the storage tank 7 is located on the left side of the supply path side connection portion 35 and the vent portion 37 .

[0112] Here, when the storage tank 7 is not attached to the supply path side connection portion 35 and the vent portion 37, the valve body 12b closes the valve opening 121 by the urging force of the coil spring 12c in the valve mechanism 12. Therefore, the treatment agent 200 in the storage tank 7 can be prevented from leaking to the outside through the valve opening 121 and the first tank side connection portion 75.

[0113] And, if Figure 7 As shown by the white arrow in FIG. 1 , the user moves the storage tank 7 to the right to make it close to the supply path side connection portion 35 and the ventilation portion 37. Figure 8As shown, regarding the storage tank 7, the first tank side connection part 75 enters the connection opening 35a of the supply path side connection part 35 so that the first tank side connection part 75 is mounted on the supply path side connection part 35. The storage tank 7 and the supply device main body 9a are connected by the treatment agent supply path 11. In addition, the first tank side connection part 75 entered into the connection opening 35a is held by the supply path side connection part 35, thereby maintaining the state of being mounted on the supply path side connection part 35.

[0114] In addition, as described above, regarding the storage tank 7, the second tank side connection part 77 extends in parallel with the first tank side connection part 75. Therefore, while the first tank side connection part 75 is attached to the supply path side connection part 35, the second tank side connection part 77 enters the first vent 37a of the vent 37. In this way, the second tank side connection part 77 is attached to the vent 37. In addition, regarding the second tank side connection part 77, the anti-detachment part 77a prevents it from falling off from the first vent 37a. As a result, the second tank side connection part 77 maintains a state of being attached to the vent 37.

[0115] Thus, the storage tank 7 is mounted on the supply road side connection portion 35 and the vent portion 37, and Figure 1 and Fig. 9 More specifically, the storage tank 7 is disposed on the left side of the right side wall 3a of the washing tank 3 in the washing space 100, and is disposed between the first lower guide member 111 and the first middle guide member 112, that is, between the first cutlery basket 13 and the second cutlery basket 14. It should be noted that even if the storage tank 7 is installed on the supply path side connection portion 35 and the ventilation portion 37, each second ventilation port 37b of the ventilation portion 37 is not completely covered by the storage tank 7.

[0116] In addition, the first tank side connection part 75 is mounted on the supply path side connection part 35 so that the pressing protrusion 35b of the supply path side connection part 35 presses the valve body 12b toward the left. Therefore, the valve body 12b overcomes the force of the coil spring 12c and opens the valve opening 121. Therefore, the tank body 71 and the supply path side connection part 35 are connected via the valve mechanism 12 and the first tank side connection part 75. As a result, Figure 8 As shown by the dotted arrow in FIG. 1 , the treatment agent 200 stored in the tank body 71 flows through the supply path body 34 of the treatment agent supply path 11 via the treatment agent filter 12 d , the communication port 122 , the valve opening 121 , and the connection opening 35 a .

[0117] In addition, the first tank side connection part 75 is mounted on the supply path side connection part 35, so that the O-ring 75a provided on the first tank side connection part 75 is elastically deformed between the first tank side connection part 75 and the connection opening 35a, and the first tank side connection part 75 and the connection opening 35a are sealed. Thus, the O-ring 75a can prevent the treatment agent 200 flowing in the connection opening 35a from leaking to the cleaning space 100 side.

[0118] Furthermore, the second tank side connection part 77 is mounted on the vent part 37, so that the tank body 71 is connected to the vent pipe 28a (see Figure 3 That is, the tank body 71 is connected to the outside of the cleaning space 100.

[0119] On the other hand, when removing the storage tank 7 from the supply path side connection part 35 and the vent part 37, the user moves the storage tank 7 to the left side of the supply path side connection part 35 and the vent part 37. As a result, the first tank side connection part 75 is removed from the supply path side connection part 35. In addition, at the same time, the second tank side connection part 77 is removed from the vent part 37. In this way, the removal of the storage tank 7 from the supply path side connection part 35 and the vent part 37 is completed. As a result, the user can replenish the treatment agent 200 in the tank body 71 outside the cleaning space 100.

[0120] Here, when the first tank-side connection portion 75 is removed from the supply passage-side connection portion 35 , the valve body 12 b closes the valve opening 121 again by the biasing force of the coil spring 12 c in the valve mechanism 12 . Therefore, the treatment agent 200 can be prevented from leaking from the valve opening 121 .

[0121] In addition, with respect to the dishwasher, the user places the first to third dishware baskets 13 to 15 carrying the objects to be washed in the washing space 100, respectively, with the storage tank 7 mounted on the supply path side connection portion 35 and the ventilation portion 37. Then, the user swings the cover 5 to the closed position and operates the operation portion 19. Thus, with respect to the dishwasher, the control portion 21 sequentially performs the washing operation, the rinsing operation, and the drying operation. It should be noted that the control portion 21 can also perform only one of the washing operation, the rinsing operation, and the drying operation.

[0122] During the washing operation, the control unit 21 opens the water supply solenoid valve provided in the water supply hose 41 and operates the water supply pump 43. Thus, water from the water supply source is sprayed as washing water from each spraying portion 300 of the first spray nozzle 31 into the washing space 100 via the water supply hose 41, the water supply pump 43, the water distributor 26 and the connecting cylinder 25a. In addition, washing water is sprayed from the water distributor 26 into the washing space 100 from each spraying portion 300 of the second and third spray nozzles 32 and 33 via the water supply pipe 27. In addition, during the washing operation, detergent for tableware is supplied into the washing space 100 by means of a detergent automatic feeding device (not shown) provided in the washing tank 3. In this way, during the washing operation, the washing water containing detergent is used to wash the objects to be washed. In addition, the washing water containing detergent is stored in the water storage unit 23. Then, the washing water is again sprayed into the washing space 100 from each spraying part 300 of the first to third spraying nozzles 31 to 33 via the water storage tank 25, the water distributor 26 and the water supply pipe 27 by the water supply pump 43. It should be noted that during the washing operation, the control unit 21 closes the water supply solenoid valve by supplying a predetermined amount of water from the water supply source.

[0123] And, when the washing time set as the washing operation has passed, the control unit 21 opens the drainage solenoid valve provided in the drainage hose 47 and operates the drainage pump 45. In addition, the control unit 21 stops the water supply pump 43. Thus, the washing water in the washing space 100 is discharged to the outside of the dishwasher through the drainage hose 47. In this way, the washing operation ends.

[0124] In the rinse operation, the control unit 21 opens the water supply electromagnetic valve and operates the water supply pump 43. As a result, water from the water supply source is sprayed from each spraying unit 300 of the first to third spraying nozzles 31 to 33 into the washing space 100 as washing water, similarly to the washing operation. In addition, in the rinse operation, the control unit 21 operates the supply device body 9a. As a result, the treatment agent 200 stored in the tank body 71 of the storage tank 7 is automatically supplied from the treatment agent supply port 9b into the washing space 100. In this way, in the rinse operation, the washing water containing the treatment agent 200 is used to rinse the object to be washed.

[0125] When the washing time set for the rinse washing operation has elapsed, control unit 21 discharges the washing water in washing space 100 to the outside of the dishwasher in the same manner as in the rinse washing operation. In this way, the rinse washing operation ends.

[0126] During the drying operation, the control unit 21 operates the air supply fan 28c. Thus, the air in the cleaning space 100 circulates in the ventilation duct 28a from each second vent 37b of the ventilation unit 37. In addition, the air in the ventilation duct 28a is supplied from the air supply unit 28d to the cleaning space 100 via the connecting hose 28b and the air supply fan 28c. In this way, during the drying operation, the air circulates between the inside of the cleaning space 100 and the outside of the cleaning space 100, and the objects to be cleaned are dried. If the cleaning time set as the drying operation has passed, the control unit 21 stops the air supply fan 28c. In this way, the drying operation ends.

[0127] In this way, in the dishwasher, the storage tank 7 attached to the supply road side connection part 35 and the ventilation part 37 is arranged in the washing space 100. Therefore, in the dishwasher, even if the treatment agent 200 attached to the surface of the tank body 71 or the like is attached to the supply road side connection part 35 via the first tank side connection part 75 when the treatment agent 200 is replenished, or the treatment agent 200 that inevitably leaks out when the storage tank 7 and the supply road side connection part 35 are attached to the supply road side connection part 35, such treatment agent 200 can be removed from the storage tank 7 or the supply road side connection part 35 by the washing water in the washing space 100. That is, in the dishwasher, the treatment agent 200 attached to the surface of the tank body 71 or the supply road side connection part 35 can be washed away by the washing water in the process of washing the object to be washed by the washing water sprayed from each of the spraying parts 300 of the first to third spraying nozzles 31 to 33 into the washing space 100.

[0128] In addition, with regard to the dishwasher, even if the treatment agent 200 cannot be completely removed by washing water, since the storage tank 7 is arranged in the washing space 100, it is easy for the user to remove the treatment agent 200 attached to the surface of the tank body 71 or the supply road side connection part 35 when the dishwasher is not working.

[0129] As a result, in this dishwasher, since the treatment agent 200 is less likely to accumulate on the supply path side connection portion 35 , the supply path side connection portion 35 and the first tank side connection portion 75 of the storage tank 7 can be prevented from being fixed and bonded due to the treatment agent 200 accumulated on the supply path side connection portion 35 .

[0130] Therefore, the dishwasher according to the embodiment has a structure including storage tank 7 storing treatment agent 200, and storage tank 7 is excellent in attachment and detachability.

[0131] In particular, in this dishwasher, the right side wall 3a of the washing tank 3 is set as the "specific wall" in the present invention. Therefore, in this dishwasher, the supply path side connection part 35 and the vent part 37 are not provided for the cover body 5, and as a result, the storage tank 7 is not attached to the cover body 5. Therefore, in this dishwasher, even if the cover body 5 is swung between the closed position and the open position, the treatment agent 200 in the tank body 71 will not leak out, and the so-called front-opening dishwasher can be well realized.

[0132] In addition, in the dishwasher, the storage tank 7 is mounted on the vent 37, so that the tank body 71 is connected to the outside of the washing space 100 through the vent communication port 73a, the second tank side connection portion 77 and the first vent 37a. Accordingly, in the dishwasher, it is difficult to form a negative pressure in the tank body 71 during the process of reducing the remaining amount of the treatment agent 200. Therefore, in the dishwasher, the treatment agent 200 in the tank body 71 can be well circulated in the treatment agent supply path 11 and even the supply device body 9a.

[0133] In addition, the storage tank 7 attached to the supply path side connection part 35 and the ventilation part 37 is arranged in the position between the first lower guide member 111 and the first middle guide member 112 in the washing space 100. Thus, the storage tank 7 is located above the water storage part 23. Therefore, in the dishwasher, the storage tank 7 can be prevented from being immersed in the washing water stored in the water storage part 23, so that the washing water is difficult to penetrate into the tank body 71.

[0134] Furthermore, in this dishwasher, the first tank side connection portion 75 and the second tank side connection portion 77 of the storage tank 7 extend in parallel toward the right side wall 3a of the washing tank 3. Therefore, in this dishwasher, the first tank side connection portion 75 can be easily attached and detached to the supply path side connection portion 35, and the second tank side connection portion 77 can be attached and detached to the ventilation portion 37 at the same time.

[0135] In addition, in this dishwasher, the remaining amount of the treatment agent 200 stored in the tank body 71 can be monitored by the float device 8 and the control unit 21, and the remaining amount of the treatment agent 200 is displayed on the display of the operation unit 19. Therefore, in this dishwasher, the user can easily know the remaining amount of the treatment agent 200, thereby improving the convenience. Here, when the control unit 21 does not monitor the remaining amount of the treatment agent 200 in the tank body 71, it determines that the storage tank 7 is not installed on the supply road side connection part 35 and the ventilation part 37. And, in this case, the warning light 19a of the operation unit 19 is lit to notify the user, so the user can easily know that the storage tank 7 is not installed on the supply road side connection part 35 and the ventilation part 37. In this regard, the convenience of the dishwasher is also improved. In addition, in this dishwasher, when control unit 21 determines whether storage tank 7 is attached to supply path side connection unit 35 and ventilation unit 37, there is no need to use a dedicated monitoring device or the like. Therefore, in this dishwasher, the convenience can be improved and the structure can be simplified.

[0136] In addition, in the dishwasher, the first cutlery basket 13 has an interference portion 13b. When the storage tank 7 is properly mounted on the supply path side connection portion 35 and the vent portion 37, when the first cutlery basket 13 is stored in the washing space 100, the interference portion 13b does not interfere with the storage tank 7 and faces the storage tank 7 from the left side. However, when the storage tank 7 is not completely mounted on the supply path side connection portion 35 and the vent portion 37, for example, the first tank side connection portion 75 does not fully enter the connection opening 35a, or the second tank side connection portion 77 does not fully enter the first vent 37a, the interference portion 13b interferes with the storage tank 7. In addition, if the interference portion 13b interferes with the storage tank 7, the user cannot move the first cutlery basket 13 backward. As a result, in the dishwasher, the user can easily know that the storage tank 7 is not completely mounted on the supply path side connection portion 35 and the vent portion 37.

[0137] As mentioned above, the present invention has been described based on the embodiment; however, the present invention is not limited to the above-mentioned embodiment, and can be applied with appropriate changes within the scope not departing from the gist of the present invention.

[0138] For example, in the dishwasher of the embodiment, dishwashing agent is stored in tank body 71 as treatment agent 200 . However, the invention is not limited thereto, and dishwashing detergent or the like may be stored in tank body 71 as treatment agent 200 .

[0139] In the dishwasher of the embodiment, left side wall 3b or rear wall 3c of washing tank 3 may be set as the "specific wall" in the present invention. In addition, cover 5 may have a structure having the "specific wall" in the present invention.

[0140] In addition, in the dishwasher of the embodiment, the float device 8 and the control unit 21 constitute the "remaining amount monitoring mechanism" in the present invention, but the present invention is not limited thereto, and the remaining amount monitoring mechanism may be configured as another structure.

[0141] In the dishwasher of the embodiment, second tank-side connection portion 77 may be omitted, and storage tank 7 may be mounted only on supply path-side connection portion 35 via first tank-side connection portion 75 .

[0142] In addition, the dishwasher of the embodiment may be provided with a dedicated monitoring device or the like that monitors whether storage tank 7 is attached to supply path side connection portion 35 and ventilation portion 37 .

[0143] In the dishwasher of the embodiment, a buzzer sound or voice guidance may be used instead of lighting warning lamp 19a to notify the user that storage tank 7 is not attached to supply path side connection portion 35 and vent portion 37.

[0144] The dishwasher of the embodiment may be configured to separately notify that storage tank 7 is attached to supply path side connection portion 35 and vent portion 37 and that storage tank 7 is not attached to supply path side connection portion 35 and vent portion 37 .

[0145] In addition, the dishwasher of the embodiment may be provided so that washing tank 3 can move in the front-rear direction relative to housing 1 .

[0146] In the dishwasher of the embodiment, a single pump capable of supplying and draining washing water may be provided instead of water supply pump 43 and drainage pump 45 .

[0147] The present invention can be used in a tableware washing machine, a tableware washing and drying machine or kitchen equipment, etc.
