Description

[Technical field]

[0001] The present invention relates to dishwashers. [Background technology]

[0002] Patent Document 1 discloses a conventional dishwasher. This dishwasher includes a washing tank, a lid, 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 lid can open and close the tank opening. The lid and the washing tank form a washing space in which the objects to be washed are washed with washing water. The washing tank is also formed with a storage section that houses the storage tank. The storage section is located outside the washing space, i.e., forward of the washing space.

[0003] The storage tank stores a processing agent to be used on the object to be cleaned. The processing agent supply device is attached to the cleaning tank and is located outside the cleaning space. The processing agent supply device supplies the processing agent stored in the storage tank into the cleaning space. The processing agent supply path is attached to the cleaning tank and is located outside the cleaning space. The processing agent supply path is connected to. The processing agent supply path has a supply path side connection portion, and the storage tank is detachably attached to this supply path side connection portion.

[0004] In this dishwasher, the storage tank is accommodated in the accommodation section and attached to the supply path side connection section. As a result, the storage tank is disposed outside the washing space and connected to the treatment agent supply device through the treatment agent supply path. In this way, the treatment agent in the storage tank is circulated to the treatment agent supply device. Meanwhile, by pulling the storage tank out of the accommodation section, the storage tank is detached from the supply path side connection section. As a result, in this dishwasher, the storage tank can be removed from the accommodation section and the storage tank can be refilled with treatment agent outside the dishwasher. [Prior art documents] [Patent documents]

[0005] [Patent Document 1] Patent Publication No. 2021-132978 Summary of the Invention [Problem to be solved by the invention]

[0006] In the conventional dishwasher, when refilling the storage tank with the treatment agent, some of the treatment agent may adhere to the surface of the storage tank, or the treatment agent may leak out from the storage tank when attaching or detaching the supply line side connector to the storage tank. When such treatment agent adheres to the supply line side connector, it gradually accumulates on the supply line side connector. Therefore, in this dishwasher, the supply line side connector and the storage tank may become stuck together due to the accumulated treatment agent, which may impair the attachment and detachment of the supply line side connector and the storage tank.

[0007] Therefore, the user of this dishwasher needs to periodically remove the treatment agent accumulated in the storage unit and the supply channel side connection part, but the storage unit and the supply channel side connection part are located outside the washing space, making it difficult for the user to remove the treatment agent.

[0008] The present invention has been made in consideration of the above-mentioned conventional situation, and has as its object to provide a dishwasher having a storage tank for storing a treatment agent, in which the storage tank is easily attached and detached. [Means for solving the problem]

[0009] The dishwasher of the present invention comprises: a washing tub having a tub opening opening toward one side; a cover that can open and close the tank opening and that, together with the cleaning tank, forms a cleaning space in which an object to be cleaned is cleaned with cleaning water; A storage tank for storing a treatment agent to be used on the object to be cleaned; a treatment agent supply device located outside the cleaning space and supplying the treatment agent stored in the storage tank into the cleaning space; a treatment agent supply passage connecting the storage tank and the treatment agent supply device, The cleaning tank or the lid has a specific wall facing the cleaning space, the treatment agent supply passage is fixed to the specific wall in a state facing the cleaning space, and has a supply passage side connection portion to which the storage tank is detachably attached, The storage tank is attached to the supply path side connection portion and is disposed within the cleaning space.

[0010] In the dishwasher of the present invention, the treatment agent supply passage has a supply passage side connection part which is fixed to the specific wall in a state facing the washing space, and the storage tank is attached to the supply passage side connection part so that the storage tank is disposed within the washing space.

[0011] As a result, in this dishwasher, even if the treating agent adhering to the surface of the storage tank when refilling the treating agent adheres to the supply line side connection part via the storage tank, or if the treating agent that inevitably leaks out when attaching or detaching the storage tank and the supply line side connection part adheres to the supply line side connection part, such treating agent can be removed from the surface of the storage tank and the supply line side connection part by the wash water in the wash space. Also, even if the treating agent cannot be completely removed by wash water, since the storage tank is located in the wash space, it is easy for the user to remove the treating agent adhering to the surface of the storage tank and the supply line side connection part.

[0012] As a result, in this dishwasher, the treatment agent is less likely to accumulate at the supply channel side connector, and adhesion between the supply channel side connector and the storage tank due to the treatment agent can be suppressed.

[0013] Therefore, in the dishwasher of the present invention, in a configuration having a storage tank for storing a treatment agent, the storage tank is easily attachable and detachable.

[0014] It is preferable that the storage tank has a tank body for storing the treatment agent, a first tank side connection part that communicates with the tank body and is detachably attached to the supply path side connection part, and a second tank side connection part that is located above the first tank side connection part and communicates between the outside of the cleaning space and the inside of the tank body.

[0015] In this case, by connecting the outside of the cleaning space to the inside of the tank body through the second tank side connecting part, it is possible to prevent negative pressure from occurring inside the tank body, and therefore the treatment agent inside the tank body can be suitably circulated to the treatment agent supply path and, ultimately, to the treatment agent supply device.

[0016] In this case, the specific wall may be provided with a ventilation part that is fixed facing the cleaning space and communicates with the outside of the cleaning space, and to which the second tank side connection part is detachably attached. It is preferable that the first tank side connection part and the second tank side connection part extend parallel to each other toward the specific wall.

[0017] This makes it possible to easily attach and detach the first tank side connecting portion to the supply passage side connecting portion, and to easily attach and detach the second tank side connecting portion to the ventilation portion.

[0018] It is also preferable that the dishwasher of the present invention further comprises a determining means capable of determining whether or not the storage tank is attached to the supply channel side connection portion, and a notifying means for notifying the result of the determination by the determining means.

[0019] In this case, the user can easily know whether or not the storage tank is attached to the supply line side connection portion through the notification by the notification means. Here, the notification means may only notify that the storage tank is attached to the supply line side connection portion based on the determination result of the determination means, or may only notify that the storage tank is not attached to the supply line side connection portion. Furthermore, the notification means may separately notify that the storage tank is attached to the supply line side connection portion and that the storage tank is not attached to the supply line side connection portion.

[0020] The apparatus may further comprise a remaining amount detection means for detecting a remaining amount of the treatment agent stored in the storage tank. Preferably, the determination means determines that the storage tank is not attached to the supply line side connection portion when the remaining amount detection means has not detected the remaining amount.

[0021] In this case, when the determining means determines whether or not the storage tank is attached to the supply line side connection portion, there is no need to use a dedicated detection device, etc. This makes it possible to simplify the structure of the dishwasher.

[0022] The cleaning tank may be formed with a water storage section that communicates with the cleaning space and stores cleaning water therein. The storage tank is preferably attached to the supply path side connector and positioned above the water storage section.

[0023] In this case, the storage tank can be prevented from being submerged in the wash water stored in the water storage section, making it difficult for wash water to enter the storage tank in this dishwasher.

[0024] The dishwasher of the present invention may further include a mounting member that is housed in the washing space while carrying an article to be washed. The mounting member preferably has an interference portion that interferes with the storage tank when the storage tank is not completely attached to the supply passage side connection portion.

[0025] In this case, because the interference portion interferes with the storage tank, the user can easily recognize that the storage tank is incompletely attached to the supply line side connector.

[0026] It is preferable that the washing tank has a specific wall, in which case the structure of the lid can be simplified.

[0027] In this case, the dishwasher of the present invention may include a housing having a housing opening that opens forward and in which a washing tub can be placed. The tub opening may open forward and communicate with the housing opening. The lid is attached to the housing so as to be swingable in the front-rear direction about a swing axis, and is preferably displaceable between an open position that opens the housing opening and the tub opening and a closed position that closes the housing opening and the tub opening.

[0028] In this case, a so-called front-opening dishwasher can be realized. Although the lid is displaced between the open position and the closed position, the washing tank has a specific wall, so that the lid does not have a supply path side connection part or a storage tank. Therefore, leakage of the treatment agent from the storage tank due to the displacement of the lid is unlikely to occur. Effect of the Invention

[0029] The dishwasher of the present invention, in its configuration having a storage tank for storing a treatment agent, is excellent in attachability and detachability of the storage tank. [Brief description of the drawings]

[0031] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings.

[0032] As shown in Figs. 1 to 3, the dishwasher of the embodiment includes a housing 1, a washing tank 3, a lid 5, a storage tank 7, a treatment agent supply device 9, a treatment agent supply passage 11, a first dish basket 13, a second dish basket 14, a third dish basket 15, an operation unit 19, and a control unit 21. The first dish basket 13 is an example of a "mounting member" in the present invention. The operation unit 19 is an example of an "alert means" in the present invention. And the control unit 21 is an example of a "determination means" in the present invention. This dishwasher is incorporated in a system kitchen (not shown). For ease of explanation, the lid 5 and the first dish basket 13 are not shown in Fig. 2, and the housing 1 and the lid 5 are not shown in Fig. 3.

[0033] In this embodiment, the front-rear direction and the up-down direction of the dishwasher are defined by the arrows shown in Figures 1 and 2. In Figure 2, the right-left direction of the dishwasher, i.e., the width direction, is defined based on the position of a user (not shown) of the dishwasher facing the dishwasher from the front, with the right side of the user being the right side of the dishwasher and the left side of the user being the left side of the dishwasher. These front-rear direction, up-down direction and left-right direction are mutually perpendicular. In Figure 3 and subsequent figures, the front-rear direction, up-down direction and left-right direction of the dishwasher are defined in accordance with Figures 1 and 2.

[0034] As shown in Figures 1 and 2, the housing 1 has a right panel 1a, a left panel 1b, a front lower panel 1c, a rear lower panel 1d, a bottom panel 1e, and a housing opening 1f. The right panel 1a and the left panel 1b are each formed in a substantially rectangular plate shape extending in the front-rear direction and the up-down direction. The right panel 1a and the left panel 1b are disposed separately from each other in the left-right direction. As a result, the right panel 1a constitutes the right side surface of the housing 1, and the left panel 1b constitutes the left side surface of the housing 1.

[0035] The front lower panel 1c and the rear lower panel 1d are formed in a substantially rectangular plate shape extending in the vertical and horizontal directions. The front lower panel 1c and the rear lower panel 1d are attached to the right panel 1a and the left panel 1b, respectively, and are disposed between the right panel 1a and the left panel 1b. More specifically, the front lower panel 1c is disposed between the right panel 1a and the left panel 1b, and is disposed at the front lower part of the right panel 1a and the left panel 1b. On the other hand, the rear lower panel 1d is disposed between the right panel 1a and the left panel 1b, and is disposed at the rear lower part of the right panel 1a and the left panel 1b. In other words, the front lower panel 1c and the rear lower panel 1d are disposed between the right panel 1a and the left panel 1b, separated from each other in the front-rear direction.

[0036] The bottom panel 1e is formed in a generally rectangular plate shape extending in the front-rear and left-right directions. The bottom panel 1e is disposed at the bottom of the housing 1, and is attached to the bottom 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 an accommodation space 10 in the lower part of the housing 1.

[0037] The housing opening 1f is formed between the right panel 1a, the left panel 1b, and the lower front panel 1c. As a result, the housing opening 1f is located above the storage space 10 and opens toward the front of the housing 1.

[0038] As shown in Fig. 2, 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 surface of the cleaning tank 3 and extends in the front-rear and up-down directions. The right side wall 3a is an example of a "specific wall" in the present invention. The left side wall 3b constitutes the left side surface of the cleaning tank 3 and extends in the front-rear and up-down directions. The right side wall 3a and the left side wall 3b face each other in the left-right direction.

[0039] The rear wall 3c constitutes the rear surface of the cleaning tank 3 and extends in the left-right and up-down directions. The rear wall 3c is disposed between the right side wall 3a and the left side wall 3b, and is connected to the rear ends 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 and front-rear directions. The upper wall 3d is disposed between the right side wall 3a, the left side wall 3b, and the rear wall 3c, and is connected to the upper ends 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 and front-rear directions. The lower wall 3e is disposed between the right side wall 3a, the left side wall 3b, and the rear wall 3c, and is connected to the lower ends of the right side wall 3a, the left side wall 3b, and the rear wall 3c. As a result, the upper wall 3d and the lower wall 3e face each other in the up-down direction.

[0040] As shown in Fig. 1, a water storage section 23 is formed in the lower wall 3e. More specifically, the water storage section 23 is formed by recessing a portion of the lower wall 3e that is approximately in the center in the front-rear and left-right directions downward. Flush water is stored in the water storage section 23. Although not shown in detail, an opening penetrating in the up-down direction is formed in the center of the water storage section 23. Details of the flush water will be described later.

[0041] The tank opening 3f is located at the front end of the cleaning tank 3. The tank opening 3f opens toward the front of the cleaning tank 3, and connects the inside and outside of the cleaning tank 3 in the front-rear direction. The right side wall 3a, the left side wall 3b, the rear wall 3c, the upper wall 3d, the lower wall 3e, and the tank opening 3f form the cleaning tank 3 into a substantially rectangular box shape that is open at the front.

[0042] As shown in Fig. 2, a first lower guide member 111, a first middle guide member 112, and a first upper guide member 113 are attached to the right side wall 3a. The first lower guide member 111 is attached to a lower part of the right side wall 3a. The first middle guide member 112 is attached to the right side wall 3a at a position spaced above the first lower guide member 111. The first upper guide member 113 is attached to the right side wall 3a at a position spaced above 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 each extend parallel to the front-rear direction along the right side wall 3a.

[0043] On the other hand, a second lower tier guide member 114, a second middle tier guide member 115, and a second upper tier guide member 116 are attached to the left side wall 3b. The second lower tier guide member 114 is attached to the left side wall 3b so as to be at the same height as the first lower tier guide member 111. The second middle tier guide member 115 is attached to the left side wall 3b so as to be at the same height as the first middle tier guide member 112. The second upper tier guide member 116 is attached to the left side wall 3b so as to be at the same height as the first upper tier guide member 113. The second lower tier guide member 114, the second middle tier guide member 115, and the second upper tier guide member 116 extend in the front-rear direction along the left side wall 3b and parallel to the first lower tier guide member 111, the first middle tier guide member 112, and the first upper tier guide member 113, respectively.

[0044] Thus, inside the cleaning tank 3, the first and second lower guide members 111, 114 face each other in the left-right direction, the first and second middle guide members 112, 115 face each other in the left-right direction, and the first and second upper guide members 113, 116 face each other in the left-right direction.

[0045] 1 and 4, a supply path side connection part 35 and a ventilation part 37 are fixed to the right side wall 3a at a position between the first lower-stage guide member 111 and the first middle-stage guide member 112. The supply path side connection part 35 will be described in detail later.

[0046] As shown in Fig. 4, the ventilation section 37 is disposed on the right side wall 3a at a distance above and rearward of the supply passage side connection section 35. The ventilation section 37 is formed with one first ventilation opening 37a and six second ventilation openings 37b. The second ventilation openings 37b are disposed around the first ventilation opening 37a and surround the first ventilation opening 37a. The first ventilation opening 37a and the second ventilation openings 37b each penetrate the right side wall 3a in the left-right direction.

[0047] The cleaning tank 3 is disposed inside the housing 1 by being fixed to the right panel 1a and the left panel 1b of the housing 1, and is located above the storage space 10 shown in Fig. 1. The cleaning tank 3 has a tank opening 3f located inside the housing opening 1f of the housing 1 and facing forward.

[0048] The cleaning tank 3 is also provided with a water reservoir case 25, a water distributor 26, a water supply duct 27, an air circulation device 28, a filter unit 29, and a locking device 50. The water reservoir case 25 is formed in a generally cylindrical shape with a bottom and an open upper end. The water reservoir case 25 is disposed within the accommodation space 10, and is located below the cleaning tank 3. The water reservoir case 25 communicates with the water storage section 23 by fixing its upper end to the lower wall 3e.

[0049] Further, the water reservoir case 25 is formed with a connecting tube portion 25a that extends through the water storage portion 23 into the inside of the cleaning tank 3. As shown in Figs. 1 and 2, the connecting tube portion 25a is formed in a cylindrical shape extending in the vertical direction. The lower end of the connecting tube portion 25a is connected to the water distributor 26. Further, a first jet nozzle 31 is rotatably attached to the upper end of the connecting tube portion 25a. As a result, the first jet nozzle 31 is disposed inside the cleaning tank 3. The first jet nozzle 31 is rotatable inside the cleaning tank 3. Further, the first jet nozzle 31 is formed with a plurality of jet portions 300.

[0050] 1, a water supply hose 41, a water supply pump 43, and a drainage pump 45 are connected to the water reservoir case 25. The water supply pump 43 and the drainage pump 45 are each disposed in the accommodation space 10, and are therefore located below the cleaning tank 3.

[0051] One end of water supply hose 41 is connected to water reservoir case 25. The other end of water supply hose 41 extends outside housing 1 and is connected to a water supply source (not shown) provided outside the dishwasher. In this way, water supply hose 41 connects water reservoir case 25 to the water supply source. Water supply pump 43 and drain pump 45 are each electrically connected to control unit 21. In addition, water supply hose 41 is provided with a water supply solenoid valve (not shown). The specific operations of water supply pump 43 and drain pump 45 will be described later.

[0052] One end of drain hose 47 is connected to water reservoir case 25. The other end of drain hose 47 extends to the outside of housing 1 and is connected to a drain outlet (not shown) provided on the outside of the dishwasher. Thus, drain hose 47 connects water reservoir case 25 to the drain outlet. Drain hose 47 is provided with a drain solenoid valve (not shown).

[0053] The water distributor 26 is disposed in the accommodation space 10, and is attached to the water storage case 25. The water distributor 26 is fixed to the bottom wall 3e of the washing tub 3 together with the water storage case 25. The water distributor 26 is also connected to a water supply pump 43.

[0054] As shown in Figures 1 and 2, the water supply duct 27 is disposed inside the washing tank 3. Washing water can flow through the water supply duct 27. The water supply duct 27 is composed of a first duct 27a, a second duct 27b, a third duct 27c, and a branch duct 27d. The first duct 27a is located above the bottom wall 3e, and extends in the front-rear direction along the bottom wall 3e. The front end of the first duct 27a is connected to the water distributor 26 at a position different from the connecting tube portion 25a.

[0055] The second duct 27b is fixed to the rear wall 3c and extends vertically within the cleaning tank 3 along the rear wall 3c. The lower end of the second duct 27b is connected to the rear end of the first duct 27a. The third duct 27c extends in the front-rear direction within the cleaning tank 3 along the upper wall 3d. The rear end of the third duct 27c is connected to the upper end of the first duct 27a. The branch duct 27d is connected to the second duct 27b at a location that is approximately the center of the second duct 27b in the vertical direction, and extends forward from the second duct 27b.

[0056] In addition, the second injection nozzle 32 is rotatably connected to the front end of the branch duct 27d, and the third injection nozzle 33 is rotatably connected to the front end of the third duct 27c. In this case, the second injection nozzle 32 and the third injection nozzle 33 are connected to the front end of the branch duct 27d and the front end of the third duct 27c from below, respectively. In addition, similar to the first injection nozzle 31, the second and third injection nozzles 32 and 33 are also formed with a plurality of injection parts 300.

[0057] The air circulation device 28 is composed of the above-mentioned ventilation section 37, the ventilation duct 28a shown in Figs. 1 and 3, the connection hose 28b shown in Fig. 3, the air supply fan 28c shown in Fig. 1, and the air supply section 28d shown in Fig. 2. As shown in Fig. 3, the ventilation duct 28a is attached to the right side wall 3a of the cleaning tank 3 and is located between the right side wall 3a and the right panel 1a of the housing 1. In other words, the ventilation duct 28a is attached to the right side wall 3a on the opposite side to the first lower guide member 111, the first middle guide member 112, and the first upper guide member 113, and is located outside the cleaning tank 3. The ventilation duct 28a is connected to the ventilation section 37. As a result, the ventilation duct 28a is in communication with the first ventilation opening 37a and each of the second ventilation openings 37b of the ventilation section 37. The ventilation duct 28a extends while curving upward toward the rear from the connection point with the ventilation portion 37, and then extends linearly downwardly from the right side wall 3a. Air can flow inside the ventilation duct 28a.

[0058] Connection hose 28b is disposed within accommodation space 10. Connection hose 28b is connected to the lower end of ventilation duct 28a and extends leftward within accommodation space 10. As shown in FIG. 1, intake fan 28c is disposed within accommodation space 10. Although detailed illustration is omitted, intake fan 28c has a housing and a fan body provided within the housing. Intake fan 28c is connected to connection hose 28b on the opposite side to ventilation duct 28a. In addition, intake fan 28c is electrically connected to control unit 21.

[0059] The air supply unit 28d shown in FIG. 2 is connected to the air supply fan 28c and is inserted through the lower wall 3e, and extends into the cleaning tank 3.

[0060] Filter unit 29 has a first filter portion 29a and a second filter portion 29b. First filter portion 29a is placed on bottom wall 3e of washing tank 3 to cover water storage portion 23 from above. Second filter portion 29b is inserted through first filter portion 29a and extends into water storage portion 23 and water storage case 25. Filter unit 29 is capable of capturing residues such as leftover food contained in washing water by first filter portion 29a and second filter portion 29b.

[0061] The locking device 50 is fixed to the upper wall 3d of the cleaning tank 3. As a result, the locking device 50 is located above the tank opening 3f and approximately in the center of the cleaning tank 3 in the left-right direction.

[0062] As shown in Fig. 1, the cover 5 has an outer panel 5a and an inner panel 5b. The outer panel 5a is formed of a plate material extending in the vertical and horizontal directions. A grip part 5c is fixed to the upper part of the outer panel 5a. The inner panel 5b is fixed to the rear of the outer panel 5a.

[0063] The cover 5 is attached to the front of the housing 1 by a hinge mechanism 51 and a damper mechanism (not shown) provided in the housing space 10. This allows the cover 5 to swing in the front-rear direction around a 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 linearly in the left-right direction of the housing 1.

[0064] The cover 5 is displaced to the closed position shown by the solid line in Fig. 1 by swinging backward around the first swing axis O1. When the cover 5 is displaced to the closed position, it closes the housing opening 1f and the tank opening 3f from the front. Then, the cover 5 displaced 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, left side wall 3b, rear wall 3c, upper wall 3d, and lower wall 3e of the cleaning tank 3 and the inner panel 5b of the cover 5.

[0065] The ventilation section 37 (see FIG. 4) faces the cleaning space 100. As a result, the first ventilation opening 37a and each second ventilation opening 37b of the ventilation section 37 communicate the cleaning space 100 with the ventilation duct 28a, thereby communicating the cleaning space 100 with the inside of the ventilation duct 28a, i.e., with the outside of the cleaning space 100. The locking device 50 shown in FIG. 1 locks the lid body 5 displaced to the closed position, thereby holding the lid body 5 in the closed position.

[0066] Meanwhile, the lid 5 swings forward around the first swing axis O1 to be displaced to the open position shown by the imaginary line in Fig. 1. When the lid 5 is displaced to the open position, it opens the housing opening 1f and the tub opening 3f forward. In this dishwasher, even if the lid 5 is displaced to the open position, the washing tub 3 does not move forward or backward relative to the housing 1, but remains positioned within the housing 1.

[0067] As shown in Fig. 5, the storage tank 7 has a tank body 71, a lid 73, a first tank side connection part 75, and a second tank side connection part 77. As shown in Fig. 6, the tank body 71 is formed in a substantially rectangular box shape with an open top. The tank body 71 is capable of storing liquid treatment agent 200 therein. Specifically, the treatment agent 200 is a rinse for tableware.

[0068] Additionally, an engagement protrusion 71a is formed on the front of the tank body 71. The engagement protrusion 71a protrudes forward from the tank body 71. Furthermore, a pair of legs 71b are provided on the lower part of the tank body 71. These legs 71b keep the storage tank 7, including the tank body 71, in a horizontal position when the storage tank 7 is placed on a kitchen countertop or table.

[0069] The lid body 73 is attached to the top of the tank body 71 and is capable of swinging up and down around a second swing axis O2 relative to the tank body 71. The lid body 73 closes the top of the tank body 71 while covering it by swinging to a first position shown by a solid line in Fig. 6. On the other hand, the lid body 73 opens the top of the tank body 71 by swinging to a second position shown by a virtual line in Fig. 6.

[0070] The lid body 73 is formed with an air vent hole 73a and an engagement claw portion 73b. The air vent hole 73a penetrates the lid body 73 in the vertical direction and communicates with the inside of the second tank side connection portion 77. The engagement claw portion 73b is formed in the front part of the lid body 73 and extends toward the engagement protrusion 71a. The engagement claw portion 73b engages with the engagement protrusion 71a when the lid body 73 swings to the first position, thereby maintaining the lid body 73 in the first position.

[0071] The lid 73 is provided with a float device 8. The float device 8, together with the control unit 21, constitutes the "remaining amount detection means" of 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. Although not shown, the float body 8a has an air chamber formed therein and a plurality of magnets provided therein. The float arm 8b is connected to the float body 8a and extends toward the lid 73. The float arm 8b is connected to the lid 73 so as to be swingable around a third swing axis O3.

[0072] The float device 8 is disposed in the tank body 71 by the cover 73 being in the first position. The float device 8 is capable of swinging in the front-rear direction around the third swing axis O3 according to the amount of the treatment agent 200 stored in the tank body 71.

[0073] 7 and 8, the first tank side connecting part 75 is integrally formed with the tank body 71. More specifically, the first tank side connecting part 75 extends in a substantially cylindrical shape from the lower right part of the tank body 71 to the right of the tank body 71, i.e., toward the right side wall 3a of the cleaning tank 3. The first tank side connecting part 75 communicates with the inside of the tank body 71.

[0074] An O-ring 75a is provided on the outer circumferential surface of the first tank side connecting portion 75. A valve mechanism 12 is provided inside the first tank side connecting portion 75. The valve mechanism 12 has a valve housing 12a, a valve body 12b, a coil spring 12c, and a treatment agent filter 12d. The valve housing 12a is formed with a valve opening 121 and a communication port 122, and also with a seat portion 123. The valve opening 121 and the communication port 122 each penetrate the valve housing 12a in the left-right direction. Note that the O-ring 75a is not shown in FIG. 5.

[0075] As shown in Figures 7 and 8, the valve body 12b is disposed in the valve housing 12a and faces the valve opening 121 from the left. The coil spring 12c is disposed between the seat portion 123 and the valve body 12b in the valve housing 12a. As shown in Figure 7, the coil spring 12c biases the valve body 12b toward the valve opening 121 so that the valve body 12b closes the valve opening 121.

[0076] The treatment agent filter 12d is attached to the left end of the valve housing 12a and extends into the tank body 71. A plurality of pores 124 are formed in the treatment agent filter 12d. The treatment agent filter 12d captures foreign matter inevitably contained in the treatment agent 200 (see FIG. 6) while allowing the treatment agent 200 to flow toward the communication port 122 of the valve housing 12a.

[0077] The second tank side connection part 77 is integrally formed with the lid body 73. More specifically, the second tank side connection part 77 protrudes upward from the lid body 73 and extends to the right of the lid body 73, i.e., toward the right side wall 3a of the cleaning 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.

[0078] The second tank side connection part 77 is tubular with a bottom, with an open right end and a closed left end. Air can flow through the inside of the second tank side connection part 77. The second tank side connection part 77 communicates with the ventilation port 73a of the lid body 73. When the lid body 73 is in the first position, the second tank side connection part 77 communicates with the inside of the tank body 71 through the ventilation port 73a. A stopper part 77a is formed on the right end of the second tank side connection part 77.

[0079] The first tank side connection part 75 of the storage tank 7 is detachable from the supply path side connection part 35, and the second tank side connection part 77 is detachable from the ventilation part 37. As shown in Fig. 1 and Fig. 8, the storage tank 7 is disposed in the cleaning space 100 by attaching the first tank side connection part 75 and the second tank side connection part 77 to the supply path side connection part 35 and the ventilation part 37, respectively. The attachment and detachment of the first tank side connection part 75 to the supply path side connection part 35 and the attachment and detachment of the second tank side connection part 77 to the ventilation part 37 will be described in detail later.

[0080] 3, the treatment agent supplying device 9 is attached to a 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 panel 1a of the housing 1. As a result, the treatment agent supplying device 9 is disposed outside the cleaning tank 3, and therefore outside the cleaning space 100.

[0081] The treatment agent supplying device 9 has a supplying device main body 9a and a treatment agent supplying port 9b. A pump (not shown) is provided inside the supplying device main body 9a. The supplying device main body 9a is electrically connected to the control unit 21 shown in FIG.

[0082] The treatment agent supply port 9b is located rearward of the supply device main body 9a and is connected to the supply device main body 9a. The treatment agent supply port 9b faces the inside of the cleaning space 100 by being fixed to the lower part of the right side wall 3a.

[0083] The treatment agent supply passage 11 has a supply passage main body 34 and a supply passage side connection part 35. The supply passage main body 34 is located between the right side wall 3a and the right side panel 1a, and extends in the vertical direction. The treatment agent 200 can flow through the supply passage main body 34. The supply passage main body 34 has a lower end serving as an apparatus connection part 34a. The supply passage main body 34 is connected to a supply device main body 9a of the treatment agent supply device 9 through the apparatus connection part 34a.

[0084] The supply path side connection part 35 is connected to the upper end of the supply path main body 34. As described above, the supply path side connection part 35 is fixed to the right side wall 3a. As shown in Figs. 7 and 8, the supply path side connection part 35 has a connection opening 35a and a pressing protrusion 35b. The connection opening 35a faces the cleaning space 100 by fixing the supply path side connection part 35 to the right side wall 3a. As a result, the connection opening 35a communicates with 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 connection opening 35a. The pressing protrusion 35b is located in the connection opening 35a and extends from the right to the left in the connection opening 35a.

[0085] The first dish basket 13, the second dish basket 14, and the third dish basket 15 shown in Fig. 1 are each capable of placing items to be washed (not shown). The first dish basket 13, the second dish basket 14, and the third dish basket 15 are classified according to the type of items to be washed. The first dish basket 13 is designed to mainly hold large items to be washed. Examples of items to be washed include tableware such as plates and bowls, as well as eating and drinking utensils such as chopsticks and cups, and cooking vessels such as pots.

[0086] The first dish basket 13 can be taken in and out of the washing space 100 while being guided in the front-to-rear direction by the first lower tier guide member 111 and the second lower tier guide member 114 shown in Fig. 2, and can be stored in the washing space 100 in a horizontal position in the front-to-rear and left-to-right directions by the first lower tier guide member 111 and the second lower tier guide member 114. Similarly, the second dish basket 14 can be taken in and out of the washing space 100 while being guided in the front-to-rear direction by the first middle tier guide member 112 and the second middle tier guide member 115, and can be stored in the washing space 100 in a horizontal position in the front-to-rear and left-to-right directions by the first middle tier guide member 112 and the second middle tier guide member 115. The third dish basket 15 can be taken in and out of the washing space 100 while being guided in the front-to-back direction by the first upper guide member 113 and the second upper guide member 116, and can be stored in the washing space 100 in a horizontal position in the front-to-back and left-to-right directions by the first upper guide member 113 and the second upper guide member 116.

[0087] Thus, in the washing space 100, the first dish basket 13, the second dish basket 14 and the third dish basket 15 are arranged in this order from bottom to top.

[0088] 9, the first dish basket 13 has a handle portion 13a and an interference portion 13b. The handle portion 13a is provided at the front portion of the first dish basket 13. The handle portion 13a can be grasped by a user when taking the first dish basket 13 in and out of the washing space 100.

[0089] Interference portion 13b is provided at the right front portion of first dish basket 13. Interference portion 13b extends leftward from the right portion of first dish basket 13, and then extends above first dish basket 13. Interference portion 13b is formed so as to face storage tank 7 from the left when first dish basket 13 is housed in washing space 100 with storage tank 7 disposed in washing space 100.

[0090] As shown in FIG. 1, the operation unit 19 is provided on the lid 5 and arranged on the upper part of the inner panel 5b. The operation unit 19 is electrically connected to the control unit 21. The operation unit 19 has a warning lamp 19a, as well as operation buttons and a display (not shown). The operation unit 19 allows the user to operate the dishwasher through the operation buttons. The operation unit 19 also displays the operating time of the dishwasher on the display, as well as the remaining amount of the treatment agent 200 stored in the tank body 71 of the storage tank 7.

[0091] Furthermore, when the storage tank 7 is not attached to the supply path side connector 35 and the ventilation section 37, the operation section 19 notifies the user of this fact. Specifically, in the operation section 19, a warning lamp 19a is turned on when the storage tank 7 is not attached to the supply path side connector 35 and the ventilation section 37. The operation section 19 may be disposed on the outer panel 5a.

[0092] The control unit 21 is provided on the cover 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 drain pump 45, the water supply solenoid valve, the drain solenoid valve, the air supply fan 28c, and the supply device main body 9a. In this way, the control unit 21 executes a washing operation, a rinsing operation, and a drying operation. The control unit 21 may be disposed within the accommodation space 10.

[0093] Furthermore, the control unit 21 detects 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. Then, when the control unit 21 has not detected the remaining amount of the treatment agent 200, it determines that the storage tank 7 is not attached to the supply line side connection unit 35 and the ventilation unit 37. As a result, the control unit 21 controls the operation unit 19 to turn on the warning lamp 19a as described above.

[0094] In the dishwasher thus configured, when attaching the storage tank 7 containing the treating agent 200 to the supply channel side connection part 35 and the ventilation part 37, the user swings the lid 5 to the open position to open the housing opening 1f and the tub opening 3f forward. Then, the user moves the storage tank 7 into the inside of the washing tub 3, i.e., into the washing space 100, and positions the storage tank 7 to the left of the supply channel side connection part 35 and the ventilation part 37 as shown in FIG.

[0095] Here, when the storage tank 7 is not attached to the supply passage side connecting portion 35 and the ventilation portion 37, the valve body 12b closes the valve opening 121 by the biasing force of the coil spring 12c in the valve mechanism 12. This prevents the treatment agent 200 in the storage tank 7 from leaking out from the valve opening 121 and the first tank side connecting portion 75 to the outside.

[0096] 7, the user moves the storage tank 7 to the right, approaching the supply path side connection part 35 and the ventilation part 37. As a result, as shown in FIG. 8, in the storage tank 7, the first tank side connection part 75 enters the connection opening 35a of the supply path side connection part 35, and the first tank side connection part 75 is attached to 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. Furthermore, the first tank side connection part 75 that has entered the connection opening 35a is held by the supply path side connection part 35, and thus maintains its attached state to the supply path side connection part 35.

[0097] As described above, in the storage tank 7, the second tank side connecting part 77 extends parallel to the first tank side connecting part 75. Therefore, at the same time that the first tank side connecting part 75 is attached to the supply passage side connecting part 35, the second tank side connecting part 77 enters the first vent hole 37a of the vent part 37. In this manner, the second tank side connecting part 77 is attached to the vent part 37. Furthermore, the second tank side connecting part 77 is prevented from coming off the first vent hole 37a by the retaining part 77a. As a result, the second tank side connecting part 77 maintains its attached state to the vent part 37.

[0098] As a result, the storage tank 7 is attached to the supply path side connecting part 35 and the ventilation part 37, and is disposed in the washing space 100, as shown in Figures 1 and 9. More specifically, the storage tank 7 is disposed in the washing space 100, on the left side of the right side wall 3a of the washing tub 3, at a location between the first lower guide member 111 and the first middle guide member 112, that is, between the first dish basket 13 and the second dish basket 14. Even when the storage tank 7 is attached to the supply path side connecting part 35 and the ventilation part 37, the second vents 37b of the ventilation part 37 are not completely covered by the storage tank 7.

[0099] Furthermore, by attaching the first tank side connecting part 75 to the supply passage side connecting part 35, the pressing protrusion 35b of the supply passage side connecting part 35 presses the valve body 12b leftward. As a result, the valve body 12b opens the valve opening 121 against the biasing force of the coil spring 12c. As a result, the tank body 71 and the supply passage side connecting part 35 communicate with each other via the valve mechanism 12 and the first tank side connecting part 75. As a result, as shown by the dashed arrow in Fig. 8, the treatment agent 200 stored in the tank body 71 flows through the treatment agent filter 12d, the communication port 122, the valve opening 121, and the connection opening 35a, inside the supply passage body 34 of the treatment agent supply passage 11.

[0100] In addition, by attaching the first tank side connecting part 75 to the supply passage side connecting part 35, the O-ring 75a provided on the first tank side connecting part 75 elastically deforms between the first tank side connecting part 75 and the connecting opening 35a, and seals the gap between the first tank side connecting part 75 and the connecting opening 35a. As a result, the O-ring 75a prevents the treatment agent 200 flowing through the connecting opening 35a from leaking into the cleaning space 100.

[0101] Then, by attaching the second tank side connecting part 77 to the ventilation part 37, the tank body 71 communicates with the inside of the ventilation duct 28a (see FIG. 3) through the ventilation communication port 73a, the second tank side connecting part 77, and the first ventilation port 37a. In other words, the tank body 71 communicates with the outside of the cleaning space 100.

[0102] On the other hand, when removing the storage tank 7 from the supply path side connection part 35 and the ventilation part 37, the user moves the storage tank 7 to the left of the supply path side connection part 35 and the ventilation part 37. This causes the first tank side connection part 75 to be removed from the supply path side connection part 35. At the same time, the second tank side connection part 77 is removed from the ventilation part 37. In this way, removal of the storage tank 7 from the supply path side connection part 35 and the ventilation part 37 is completed. As a result, the user can refill the treatment agent 200 into the tank body 71 outside the cleaning space 100.

[0103] Here, when the first tank side connecting part 75 is detached from the supply passage side connecting part 35, in the valve mechanism 12, the valve body 12b closes the valve opening 121 again due to the biasing force of the coil spring 12c. Therefore, leakage of the treatment agent 200 from the valve opening 121 is prevented.

[0104] Then, in this dishwasher, with the storage tank 7 attached to the supply channel side connection part 35 and the ventilation part 37, the user places the first to third dish baskets 13-15, on which the items to be washed are placed, in the washing space 100. After that, the user swings the lid body 5 to the closed position and operates the operating part 19. As a result, in this dishwasher, the control part 21 executes the washing operation, the rinsing operation and the drying operation in that order. Note that the control part 21 can also execute only any one of the washing operation, the rinsing operation and the drying operation.

[0105] In the washing operation, the control unit 21 opens the water supply solenoid valve provided on the water supply hose 41 and operates the water supply pump 43. As a result, water from the water supply source is sprayed as washing water from each spraying portion 300 of the first spray nozzle 31 through the water supply hose 41, the water supply pump 43, the water distributor 26, and the connecting tube portion 25a into the washing space 100. Also, washing water is sprayed from the water distributor 26 through the water supply duct 27 into the washing space 100 from each spraying portion 300 of the second and third spray nozzles 32 and 33. Furthermore, in the washing operation, dish detergent is supplied into the washing space 100 by an automatic detergent dispenser (not shown) provided in the washing tub 3. Thus, in the washing operation, the washing object is washed with washing water containing detergent. Also, the washing water containing detergent is stored in the water storage portion 23. This cleaning water is then sprayed again into the cleaning space 100 from each of the spraying parts 300 of the first to third spray nozzles 31 to 33 by the water supply pump 43 via the water storage case 25, the water distributor 26 and the water supply duct 27. During cleaning operation, a predetermined amount of water is supplied from the water supply source, and the control unit 21 closes the water supply solenoid valve.

[0106] Then, when the washing time set for the washing operation has elapsed, the control unit 21 opens the drain solenoid valve provided in the drain hose 47 and operates the drain pump 45. The control unit 21 also stops the water supply pump 43. This causes the washing water in the washing space 100 to be discharged outside the dishwasher through the drain hose 47. In this way, the washing operation ends.

[0107] In the rinsing operation, the control unit 21 opens the water supply solenoid valve and operates the water supply pump 43. As a result, similar to the washing operation, water from the water supply source is sprayed as washing water from each of the spraying parts 300 of the first to third spray nozzles 31 to 33 into the washing space 100. Also, in the rinsing operation, the control unit 21 operates the supply device main body 9a. As a result, the treatment agent 200 stored in the tank main 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 rinsing operation, the object to be washed is rinsed with washing water containing the treatment agent 200.

[0108] When the washing time set for the rinsing operation has elapsed, the control unit 21 discharges the washing water in the washing space 100 to the outside of the dishwasher, in the same manner as in the washing operation. In this way, the rinsing operation ends.

[0109] In the drying operation, the control unit 21 operates the air supply fan 28c. This causes the air in the cleaning space 100 to flow through the ventilation duct 28a from each second ventilation port 37b of the ventilation unit 37. The air in the ventilation duct 28a is supplied from the air supply unit 28d to the cleaning space 100 via the connection hose 28b and the air supply fan 28c. In this way, in the drying operation, the object to be cleaned is dried while air circulates between the inside and outside of the cleaning space 100. When the cleaning time set for the drying operation has elapsed, the control unit 21 stops the air supply fan 28c. In this way, the drying operation is terminated.

[0110] In this way, in this dishwasher, the storage tank 7 attached to the supply channel side connection part 35 and the ventilation part 37 is disposed in the washing space 100. Therefore, in this dishwasher, even if the treatment agent 200 attached to the surface of the tank body 71 or the like adheres to the supply channel side connection part 35 via the first tank side connection part 75 when refilling the treatment agent 200, or even if the treatment agent 200 that unavoidably leaks out when attaching or detaching the storage tank 7 and the supply channel side connection part 35 adheres to the supply channel side connection part 35, such treatment agent 200 can be removed from the storage tank 7 and the supply channel side connection part 35 by the washing water in the washing space 100. In other words, in this dishwasher, the treatment agent 200 attached to the surface of the tank body 71 or the supply channel side connection part 35 can be washed away by the washing water sprayed into the washing space 100 from each of the spray parts 300 of the first to third spray nozzles 31 to 33 in the process of washing the object to be washed.

[0111] Furthermore, in this dishwasher, even if the treatment agent 200 cannot be completely removed by the wash water, since the storage tank 7 is located within the wash space 100, the user can easily remove the treatment agent 200 adhering to the surface of the tank body 71 or the supply line side connection part 35 when the dishwasher is not in operation.

[0112] As a result, in this dishwasher, since the treatment agent 200 is less likely to accumulate at the supply channel side connection part 35, adhesion between the supply channel side connection part 35 and the first tank side connection part 75 of the storage tank 7 due to the treatment agent 200 accumulated at the supply channel side connection part 35 can be prevented.

[0113] Therefore, in the dishwasher of the embodiment, in a configuration having the storage tank 7 for storing the treatment agent 200, the storage tank 7 is excellent in attachability and detachability.

[0114] In particular, in this dishwasher, the right side wall 3a of the washing tub 3 is defined as the "specific wall" in the present invention. Therefore, in this dishwasher, the supply channel side connection part 35 and the ventilation part 37 are not provided on the lid body 5, and as a result, the storage tank 7 is not attached to the lid body 5. Therefore, in this dishwasher, even if the lid body 5 is swung between the closed position and the open position, the treatment agent 200 in the tank body 71 does not leak, and it is possible to preferably realize a so-called front-open type dishwasher.

[0115] In addition, in this dishwasher, by attaching the storage tank 7 to the ventilation section 37, the tank body 71 communicates with the outside of the washing space 100 through the ventilation connection port 73a, the second tank side connection section 77, and the first ventilation port 37a. As a result, in this dishwasher, negative pressure is unlikely to occur inside the tank body 71 as the remaining amount of the treatment agent 200 decreases. Therefore, in this dishwasher, the treatment agent 200 in the tank body 71 can be suitably circulated to the treatment agent supply path 11 and, ultimately, to the supply device body 9a.

[0116] Furthermore, the storage tank 7 attached to the supply path side connection part 35 and the ventilation part 37 is disposed in the washing space 100 at a location between the first lower guide member 111 and the first middle guide member 112. As a result, the storage tank 7 is located above the water storage part 23. Therefore, in this dishwasher, the storage tank 7 can be prevented from being immersed in the wash water stored in the water storage part 23, and therefore the wash water is less likely to enter the tank body 71.

[0117] Furthermore, in this dishwasher, first tank side connection part 75 and second tank side connection part 77 of storage tank 7 extend in parallel toward right side wall 3a of washing tub 3. Therefore, in this dishwasher, first tank side connection part 75 can be attached and detached to supply passage side connection part 35 and second tank side connection part 77 can be attached and detached to ventilation part 37 easily and simultaneously.

[0118] In addition, in this dishwasher, the float device 8 and the control unit 21 can detect the remaining amount of the treatment agent 200 stored in the tank body 71, 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, which is highly convenient. Here, when the remaining amount of the treatment agent 200 in the tank body 71 has not been detected, the control unit 21 determines that the storage tank 7 is not attached to the supply path side connection unit 35 and the ventilation unit 37. In this case, the warning lamp 19a of the operation unit 19 is turned on to notify the user, so that the user can easily know that the storage tank 7 is not attached to the supply path side connection unit 35 and the ventilation unit 37. In this respect, the dishwasher is also highly convenient. Furthermore, in this dishwasher, when the control unit 21 determines whether the storage tank 7 is attached to the supply path side connection unit 35 and the ventilation unit 37, there is no need to use a dedicated detection device or the like. This makes it possible to simplify the structure of this dishwasher while still improving its user-friendliness.

[0119] Furthermore, in this dishwasher, the first dish basket 13 has an interference part 13b. When the storage tank 7 is properly attached to the supply path side connection part 35 and the ventilation part 37, this interference part 13b faces the storage tank 7 from the left side without interfering with the storage tank 7 when the first dish basket 13 is housed in the washing space 100. However, when the storage tank 7 is not completely attached to the supply path side connection part 35 and the ventilation part 37, for example, when the first tank side connection part 75 is not fully inserted into the connection opening 35a or the second tank side connection part 77 is not fully inserted into the first ventilation opening 37a, the interference part 13b interferes with the storage tank 7. If the interference part 13b interferes with the storage tank 7, the user cannot move the first dish basket 13 backward. As a result, in this dishwasher, the user can easily know that the storage tank 7 is attached to the supply channel side connection part 35 and the ventilation part 37 in an incomplete state.

[0120] Although the present invention has been described above with reference to the embodiments, it goes without saying that the present invention is not limited to the above embodiments and can be modified as appropriate without departing from the spirit of the present invention.

[0121] For example, in the dishwasher of the embodiment, a rinse for dishes is stored in the tank body 71 as the treatment agent 200. However, this is not limiting, and a detergent for dishes or the like may be stored in the tank body 71 as the treatment agent 200.

[0122] In the dishwasher of the embodiment, the left side wall 3b or the rear wall 3c of the washing tub 3 may be the "particular wall" of the present invention. The lid 5 may be configured to have the "particular wall" of the present invention.

[0123] In addition, in the dishwasher of the embodiment, the float device 8 and the control unit 21 constitute the "remaining amount detection means" of the present invention, but the remaining amount detection means is not limited to this, and may have another configuration.

[0124] In addition, in the dishwasher of the embodiment, the second tank side connector 77 may be omitted, and the storage tank 7 may be attached only to the supply channel side connector 35 via the first tank side connector 75.

[0125] In addition, in the dishwasher of the embodiment, a dedicated detection device or the like for detecting whether or not the storage tank 7 is attached to the supply channel side connection part 35 and the ventilation part 37 may be provided.

[0126] In addition, in the dishwasher of the embodiment, instead of lighting the warning lamp 19a, a buzzer sound or audio guide, etc. may be used to notify the user that the storage tank 7 is not attached to the supply path side connection part 35 and the ventilation part 37.

[0127] In addition, the dishwasher of the embodiment may be configured to provide a notification that the storage tank 7 is attached to the supply path side connection part 35 and the ventilation part 37, and a notification that the storage tank 7 is not attached to the supply path side connection part 35 and the ventilation part 37.

[0128] In the dishwasher of the embodiment, the washing tank 3 may be provided so as to be movable in the front-rear direction relative to the housing 1.

[0129] In addition, in the dishwasher of the embodiment, water supply pump 43 and drain pump 45 may be replaced with one pump capable of supplying wash water and draining wash water. [Industrial Applicability]
