Description

The present invention relates to a dishwasher.

Patent Document 1 discloses a conventional dishwasher. This dishwasher includes a housing and a moving body. The housing has a housing opening that is open at the front. The moving body is arranged to be movable in the front-rear direction relative to the housing.

The moving body has a washing tank, a storage tank, and a supply device. A washing space is formed in the washing tank. The washing space washes the objects while housing them therein. The storage tank is fixed to the washing tank and is located outside the washing space. The storage tank stores a liquid treatment agent to be used on the objects to be washed. The storage tank is provided with a supply port and a storage chamber. The supply port supplies the treatment agent. The storage chamber is located downstream of the supply port in the flow direction of the treatment agent, and stores the treatment agent supplied from the supply port. The supply device is fixed to the storage tank and is located outside the washing space. The supply device supplies the treatment agent stored in the storage tank into the washing space. Note that the treatment agent in this dishwasher is a rinse.

In this dishwasher, in addition to washing the objects contained in the washing space, a supply device supplies a treatment agent stored in a storage tank into the washing space. This means that the user does not need to supply the treatment agent directly to the washing space, and the dishwasher can easily treat the objects with the treatment agent.

JP 2019-180464 A

In addition to liquid processing agents, there are also solid processing agents in powder or tablet form. In dishwashers that use liquid processing agents, the storage tank and supply device are designed specifically for liquid processing agents. For this reason, if a solid processing agent is replenished into such a storage tank, not only will the supply device not supply the processing agent to the washing space, but it may also cause the storage tank and supply device to break down. Therefore, if the wrong type of processing agent is replenished into the storage tank, it is necessary to remove the processing agent from the storage tank.

However, in the above-mentioned conventional dishwasher, even if a solid treatment agent is mistakenly refilled into the storage tank, it is difficult for the user to notice this. In addition, in this dishwasher, it is also difficult to remove the treatment agent that has reached the storage chamber from the refill port.

The present invention was made in consideration of the above-mentioned conventional situation, and the problem to be solved is to provide a dishwasher that can prevent breakdowns in the storage tank and the supply device even if a solid treatment agent is mistakenly replenished to the storage tank.

The dishwasher of the present invention comprises: a housing having a housing opening that is open at the front;
a movable body provided so as to be movable in a front-rear direction relative to the housing,
The moving body includes a cleaning tank having a cleaning space formed therein for storing an object to be cleaned and cleaning the object,
a storage tank attached to the cleaning tank and positioned outside the cleaning space, for storing a liquid treatment agent to be used on the object to be cleaned;
a supply device attached to the cleaning tank and positioned outside the cleaning space, the supply device supplying the treatment agent stored in the storage tank into the cleaning space,
The storage tank has a supply port for supplying the treatment agent,
a storage chamber located downstream of the supply port in a flow direction of the treatment agent, the storage chamber storing the treatment agent supplied through the supply port;
The liquid supply device is characterized in that a guide portion is provided, which is located between the supply port and the storage chamber, and which extends in a labyrinth shape and communicates with the supply port and the storage chamber.

In the dishwasher of the present invention, a liquid treatment agent is stored in a storage tank, and the treatment agent is supplied to the washing space by a supply device. In other words, the storage tank and the supply device are designed exclusively for liquid treatment agents. Here, the storage tank is provided with a supply port, a storage chamber, and a guide portion, and the guide portion is located between the supply port and the storage chamber in the flow direction of the treatment agent. Therefore, in this dishwasher, the treatment agent supplied from the supply port passes through the guide portion without directly reaching the storage chamber.

Here, the guide section extends in a labyrinth shape and communicates with the supply port and the storage chamber. Therefore, when a user supplies liquid processing agent through the supply port, this processing agent can reach the storage chamber, although the flow of this processing agent is likely to be hindered to a certain extent as it passes through the guide section. In contrast, when a user supplies solid processing agent to the storage tank, it is difficult or impossible for this processing agent to pass through the guide section. For this reason, the user is likely to sense something is wrong, and as a result, is likely to realize that they have mistakenly supplied the storage tank with solid processing agent.

In addition, in this dishwasher, when a user refills the storage tank with solid treatment agent, the treatment agent is less likely to reach the storage chamber and be stored there. Therefore, in this dishwasher, it is easier to remove the treatment agent from the storage tank compared to when the solid treatment agent has already reached the storage chamber.

Therefore, with the dishwasher of the present invention, even if a solid treatment agent is mistakenly supplied to the storage tank, it is possible to prevent breakdowns in the storage tank or the supply device.

The guide section may have a first guide wall through which the treatment agent refilled from the refill port can flow, a first opening that communicates with the first guide wall and through which the treatment agent that has flowed through the first guide wall can flow, a second guide wall that is located downstream of the first opening in the flow direction and through which the treatment agent that has flowed through the first opening can flow, and a second opening that is located downstream of the first guide wall and the first opening in the flow direction and communicates with the second guide wall and through which the treatment agent that has flowed through the second guide wall can flow. It is preferable that the first opening and the second opening are located at different positions when the storage tank is viewed from above the moving body.

In this case, it is possible to simplify the configuration of the guide section while forming the guide section into a labyrinth shape. In addition, by having the first opening and the second opening in different positions when the storage tank is viewed from above the moving body, it is possible to effectively prevent the treatment agent that has flowed through the first opening from flowing through the second opening without passing through the second guide wall.

It is preferable that the first guide wall is inclined downward toward the first opening. In this case, the treatment agent can be caused to flow smoothly to the first opening by its own weight.

It is also preferable that the second guide wall slopes upward toward the second opening. In this case, it is virtually impossible for a solid processing agent to flow through the second guide wall toward the second opening, and the solid processing agent accumulates on the second guide wall. This makes it easier for a user to notice if a solid processing agent is mistakenly refilled through the refill port, and can reliably prevent such processing agents from being stored in the storage chamber. Furthermore, the accumulation of solid processing agents on the second guide wall makes it easier to remove such processing agents.

The storage tank preferably has a tank body provided with a storage chamber and fixed to the cleaning tank, and an auxiliary tank provided with a refill port and a guide portion and detachably attached to the tank body .

In this case, even if solid processing agent is mistakenly refilled through the refill port, the processing agent in the auxiliary tank can be easily removed by removing the auxiliary tank from the tank body.

It is preferable that the auxiliary tank is provided with a filter located at least either between the supply port and the guide section or between the guide section and the storage chamber to prevent foreign matter from entering the storage chamber.

In this case, even if foreign matter enters the auxiliary tank together with the treatment agent from outside the storage tank when refilling the treatment agent, the foreign matter is less likely to reach the storage chamber and ultimately the supply device. Therefore, this dishwasher can effectively prevent damage to the storage tank and supply device caused by foreign matter. In addition, because the auxiliary tank is detachable from the tank body, it is also easy to remove foreign matter captured by the filter.

The tank body may also be provided with an inlet located upstream of the storage chamber in the flow direction for allowing the auxiliary tank to enter the tank body, and a supply port located downstream of the storage chamber in the flow direction for allowing the treatment agent stored in the storage chamber to flow to the supply device. When the tank body is viewed from above the moving body, it is preferable that the inlet and the supply port are located at different positions.

In this case, even if the solid treatment agent is mistakenly supplied through the inlet when the auxiliary tank is removed from the tank body, the treatment agent can be effectively prevented from reaching the supply port and ultimately the supply device from the inlet.

The dishwasher of the present invention can prevent damage to the storage tank or the supply device even if a solid treatment agent is mistakenly added to the storage tank.

The following describes an embodiment of the present invention with reference to the drawings.

As shown in Figures 1 and 2, the dishwasher 1 of the embodiment is incorporated into a system kitchen 100 and is installed below the countertop CT1 of the system kitchen 100. The dishwasher 1 includes a housing 3 and a moving body 5.

In this embodiment, the front-rear direction and the up-down direction of the dishwasher 1 are defined by the arrows shown in Figs. 1 and 2. Also, Fig. 3 defines the front-rear direction of the dishwasher 1 corresponding to Figs. 1 and 2, as well as the left-right direction, i.e., the width direction, of the dishwasher 1. Then, Figs. 4 and onward define the front-rear direction, up-down direction, and left-right direction of the dishwasher 1 corresponding to Figs. 1 to 3. The front-rear direction, up-down direction, and left-right direction are mutually perpendicular.

As shown in Figures 1 and 2, the housing 3 is formed in a substantially rectangular box shape. The housing 3 has a housing opening 3h. The housing opening 3h is located at the front of the housing 3. The housing opening 3h is open at the front, and connects the inside and outside of the housing 3.

Inside the housing 3, a cover member 35, a water supply pipe P1, a water supply solenoid valve 37, and a drain pipe P2 are provided. Inside the housing 3, the cover member 35 is disposed in a position above the moving body 5.

The water supply pipe P1 supplies water to the supply device 13 from a water supply source (not shown) provided outside the dishwasher 1. The water supply solenoid valve 37 opens and closes the water supply pipe P1 to switch between supplying and stopping water to the supply device 13. The drain pipe P2 drains the washing water in the washing tub 7 to the outside of the dishwasher 1. The washing water, in addition to the supply device 13 and the washing tub 7, will be described later.

The mobile body 5 has a cleaning tank 7, a front panel 9, an upper panel 11, a control unit C1, a supply device 13, and a storage tank 15.

The washing tank 7 is generally rectangular. A washing space 7h, an exhaust passage 7a, and a heater chamber 72 are formed in the washing tank 7. The washing space 7h is located approximately in the center of the washing tank 7 in the front-rear and left-right directions. The washing space 7h is open at the top and can accommodate tableware TW1 therein, and washes the accommodated tableware TW1. The tableware TW1 is, for example, eating and drinking vessels such as bowls, plates, and glasses, as well as eating and drinking utensils such as chopsticks, spoons, and forks, and is an example of the "item to be washed" in the present invention. A dish basket 70 is also arranged inside the washing space 7h. The tableware TW1 is placed in the dish basket 70.

The cleaning space 7h also has a water storage chamber 71. The water storage chamber 71 is located at the bottom of the cleaning tank 7. The water storage chamber 71 is capable of storing cleaning water. The water storage chamber 71 is also connected to the drain pipe P2 at the bottom. Here, the cleaning water may be composed only of water that has flowed through the water supply pipe P1, or may be composed of water that has flowed through the water supply pipe P1 mixed with liquid detergent 300 (see FIG. 8). The detergent 300 is an example of a "treatment agent" in the present invention.

The water storage chamber 71 is provided with a nozzle 73 and a water storage chamber filter 74. The nozzle 73 has multiple discharge holes, and can spray cleaning water from each discharge hole into the cleaning space 7h. Here, the spray direction of the cleaning water from the nozzle 73 can be changed in various directions so that it can wash the tableware TW1 as well as the inner wall surface of the cleaning space 7h and the dish basket 70. The water storage chamber filter 74 removes foreign matter such as food scraps that have become mixed in the cleaning water.

The exhaust passage 7a extends forward inside the washing tub 7 while communicating with the washing space 7h at its rear end, and opens to the front panel 9. As a result, the exhaust passage 7a communicates between the washing space 7h and the outside of the washing tub 7, i.e., the outside of the dishwasher 1. The exhaust passage 7a may be configured to communicate with the washing space 7h and open to the top panel 11.

The heater chamber 72 is located at the rear lower part of the cleaning tank 7. A heater 72a is provided inside the heater chamber 72. The heater 72a is capable of heating the cleaning water and the air in the cleaning space 7h to a predetermined temperature.

The cleaning tank 7 is also provided with a pump 75, a drying fan 77, and a water level sensor (not shown). The pump 75 is attached to the bottom of the water storage chamber 71. When operating in forward rotation, the pump 75 supplies cleaning water that has passed through the water storage chamber filter 74 in the water storage chamber 71 to the nozzle 73. When operating in reverse rotation, the pump 75 circulates the cleaning water to the drain pipe P2.

The drying fan 77 can introduce air from outside the dishwasher 1 and supply it into the washing space 7h by rotating. The air supplied into the washing space 7h by the drying fan 77 flows through the washing space 7h while drying the tableware TW1, and is then discharged to the outside of the washing tub 7 through the exhaust passage 7a. The water level sensor allows some of the washing water to flow into it, and detects the level of the washing water in the washing space 7h through this washing water.

As shown in FIG. 3, the front panel 9 is formed in the shape of a rectangular plate extending in the vertical and horizontal directions. The front panel 9 is located in front of the cleaning tank 7 and is attached to the front part of the cleaning tank 7. In this case, as shown in FIG. 1 and FIG. 2, the front panel 9 is attached to the front part of the cleaning tank 7 while forming an accommodation space 90 between the front panel 9 and the cleaning tank 7. In this way, the front panel 9 constitutes the front surface of the moving body 5. Note that in FIG. 3, the front panel 9 is shown by virtual lines for ease of explanation.

As shown in FIG. 4, the top panel 11 is located in front of and above the cleaning tank 7, and is attached to the top of the cleaning tank 7. As a result, the top panel 11 is located above the front panel 9 in the moving body 5. The top panel 11 has a main body portion 11a and an extension portion 11b. The main body portion 11a is located at the front end of the top panel 11, and extends in a generally rectangular shape in the left-right direction. As shown in FIG. 3, a grip portion 111 is provided at approximately the center of the main body portion 11a in the left-right direction.

The extension 11b is integral with the main body 11a and extends rearward from the main body 11a. As a result, the extension 11b is located at the top of the cleaning tank 7 and is adjacent to the cleaning space 7h in the front-rear direction. A communication port 112 is formed in the extension 11b. The communication port 112 has a rectangular shape that penetrates the extension 11b in the vertical direction and communicates with the storage space 90. A lid 112a is attached to the extension 11b so as to be able to swing. The lid 112a can be displaced between a closed position shown by a solid line in FIG. 4 and an open position shown by a virtual line. In the closed position, the lid 112a covers the communication port 112 from above and closes the communication port 112. On the other hand, in the open position, the lid 112a opens the communication port 112 to the outside of the moving body 5.

Furthermore, the extension portion 11b is provided with an operation unit 40 and a liquid crystal panel 41. The operation unit 40 is composed of a number of operation buttons, and the user of the dishwasher 1 operates the dishwasher 1. Specifically, the user selects the type of wash operation and the time of the wash operation through the operation unit 40. The liquid crystal panel 41 displays the type and time of the wash operation selected by the user. Furthermore, the liquid crystal panel 41 also functions as an alarm device that displays the remaining amount of detergent 300 stored in the storage tank 15. Note that an alarm lamp or the like may be used as the alarm device. Also, the remaining amount of detergent 300 stored in the storage tank 15 may be confirmed by the user's visual inspection without using the liquid crystal panel 41 or the alarm lamp.

As shown in FIG. 3, the control unit C1 is attached to the front of the washing tub 7 and is located within the storage space 90. The control unit C1 stores a control program for controlling the operation of the dishwasher 1. The control unit C1 is electrically connected to the operation unit 40, the liquid crystal panel 41, the water supply solenoid valve 37, the heater 72a, the pump 75, and the drying fan 77, as well as to the supply device 13 and the water level sensor. The control unit C1 controls the supply device 13 and the like based on the control program, and operates the dishwasher 1.

The supply device 13 is attached to the front lower part of the cleaning tank 7 and is located at the bottom within the storage space 90. As shown in Figures 1 and 2, the supply device 13 has a device body 13a, a supply passage 13b, and a connection passage 13c. The device body 13a is connected to the water supply pipe P1. Although detailed illustration is omitted, the device body 13a is provided with a water supply pump, an electric motor for operating the water supply pump, and solenoid valves that can open and close the supply passage 13b and the connection passage 13c. The supply passage 13b connects the device body 13a and the cleaning tank 7, and communicates the device body 13a with the water storage chamber 71. The connection passage 13c extends upward from the device body 13a and can be connected to the storage tank 15.

In the supply device 13, water flows from the water supply pipe P1 to the device body 13a. The device body 13a then supplies water to the water storage chamber 71 and ultimately to the cleaning space 7h through the supply passage 13b. In addition, in the supply device 13, detergent 300 (see FIG. 8) in the storage tank 15 flows into the device body 13a through the connection passage 13c. As a result, the device body 13a supplies detergent 300 to the water storage chamber 71 together with water.

The storage tank 15 has a tank body 17, a float 18, and an auxiliary tank 19. The tank body 17, the float 18, and the auxiliary tank 19 are all made of resin. The storage tank 15 stores liquid detergent 300. In other words, the storage tank 15 is designed exclusively for the liquid detergent 300. The supply device 13 is also designed exclusively for the liquid detergent 300.

As shown in FIG. 5, the tank body 17 has a first bottom wall 17a, an upper wall 17b, and a first peripheral wall 17c. The first bottom wall 17a is located at the bottom of the tank body 17. The upper wall 17b is located at the top of the tank body 17. The first peripheral wall 17c is located between the first bottom wall 17a and the upper wall 17b. The first peripheral wall 17c extends in the vertical direction and goes around the first bottom wall 17a and the upper wall 17b in the circumferential direction along the outer periphery of the first bottom wall 17a and the upper wall 17b, and is connected to the first bottom wall 17a and the upper wall 17b. The first bottom wall 17a, the upper wall 17b, and the first peripheral wall 17c form a substantially rectangular box shape extending in the front-rear, up-down, and left-right directions, and a storage chamber 170 is provided inside.

More specifically, the first bottom wall 17a has a first body portion 171 and a supply port 172. The first body portion 171 has a generally rectangular shape extending in the front-rear and left-right directions. Here, the first body portion 171 is designed so that the length in the left-right direction is longer than the length in the front-rear direction. The supply port 172 is integrally formed with the first body portion 171 and penetrates the first body portion 171 in the up-down direction. The supply port 172 is disposed on the first body portion 171 to the left of the center in the left-right direction. In other words, the supply port 172 is located on the left side of the first bottom wall 17a. The supply port 172 communicates with the storage chamber 170 at the lower part of the storage chamber 170. The supply port 172 is provided with a connection portion 172a. The supply port 172 is connected to the connection passage 13c of the supply device 13 through the connection portion 172a.

The upper wall 17b has a second body portion 173 and a holding portion 174. The second body portion 173 has a generally rectangular shape extending in the front-rear and left-right directions. The second body portion 173 is designed to be longer in the left-right direction than in the front-rear direction so as to conform to the shape of the first body portion 171. The holding portion 174 is integrally formed with the second body portion 173 and extends upward from the second body portion 173 in a rectangular tubular shape. The holding portion 174 is located on the second body portion 173 to the right of the center in the left-right direction. In other words, the holding portion 174 is located on the right side of the upper wall 17b. The holding portion 174 is connected to the storage chamber 170 at the top of the storage chamber 170.

In addition, an inlet 175 is formed at the upper end of the holding portion 174. As shown in FIG. 7, the inlet 175 is formed in a substantially rectangular shape, and opens the storage chamber 170 upward. Here, since the holding portion 174 is located on the right side of the upper wall 17b, the inlet 175 is also located on the right side of the upper wall 17b. Note that, in FIG. 7, to facilitate explanation, the float 18 is not shown, and the first mounting screw 21a and the second mounting screw 21b, which will be described later, are also not shown.

As shown in FIG. 5, the first peripheral wall 17c is composed of a first portion 176 and a second portion 177. The first portion 176 constitutes the lower portion of the first peripheral wall 17c. The first portion 176 extends upward while connecting with the first main body portion 171 of the first bottom wall 17a. The first portion 176 is also formed with a first mounting flange 178, a second mounting flange 179, and a retaining groove 701. The first mounting flange 178 and the second mounting flange 179 are located outside the storage chamber 170 and are disposed at the left and right ends of the first portion 176, respectively. The retaining groove 701 is located to the right of the first portion 176 and is disposed within the storage chamber 170. Note that the retaining groove 701 may be located to the left of the first portion 176 as long as it is within the storage chamber 170.

The second portion 177 constitutes the upper portion of the first peripheral wall 17c. The second portion 177 extends downward while being connected to the second main body portion 173 of the upper wall 17b. The second portion 177 is joined to the first portion 176 when the float 18 is housed in the storage chamber 170. As a result, the second portion 177 is integral with the first portion 176.

3, in the tank body 17, the supply port 172 is connected to the device body 13a of the supply device 13 through the connection part 172a and the connection passage 13c. In this state, the first mounting flange 178 is fixed to the front of the cleaning tank 7 by the first mounting screw 21a, and the second mounting flange 179 is fixed to the front of the cleaning tank 7 by the second mounting screw 21b. In this way, the tank body 17 is fixed to the front of the cleaning tank 7 while connected to the supply device 13. As a result, in the tank body 17, the inlet 175 is located below the communication port 112 (see FIG. 4) of the upper panel 11 and faces the communication port 112. Although not shown, the first bottom wall 17a and the first peripheral wall 17c are provided with a detection member capable of detecting the magnetism of the magnet 802 described later. The detection member is electrically connected to the control unit C1.

As described above, in the tank body 17, the inlet 175 is disposed on the right side of the top wall 17b. Meanwhile, the supply port 172 is disposed on the left side of the first bottom wall 17a. Therefore, when the tank body 17 is viewed from the direction D1 shown in FIG. 6, that is, when the tank body 17 is viewed from above the movable body 5 while fixed to the front part of the cleaning tank 7, the inlet 175 and the supply port 172 are disposed apart in the left-right direction, as shown in FIG. 7. More specifically, the supply port 172 is not located directly below the inlet 175, and the inlet 175 and the supply port 172 are disposed completely separated in the left-right direction without overlapping with each other in the up-down direction.

As shown in FIG. 5, the float 18 has a float body 18a, an arm 18b, and a connecting shaft 18c. The float body 18a is formed in a substantially rectangular box shape, and an air chamber 801 is formed inside. The air chamber 801 is sealed from the outside of the float body 18a. A magnet 802 is provided inside the air chamber 801. The magnet 802 is fixed to the float body 18a. The shape of the float body 18a can be designed as appropriate.

The arm 18b extends in the left-right direction and is connected to the float body 18a at its left end. The arm 18b extends upward with its right end moving away from the float body 18a. The connecting shaft 18c is provided at the right end of the arm 18b and is integral with the arm 18b. The connecting shaft 18c extends linearly in the front-rear direction.

When the float 18 is housed in the storage chamber 170, the connecting shaft 18c is held in a holding groove 701 of the first peripheral wall 17c so that the float 18 can swing. This connects the float 18 to the first peripheral wall 17c through the connecting shaft 18c. The float 18 can swing up and down within the storage chamber 170 around the swing axis, with the axis of the connecting shaft 18c serving as the swing axis.

The auxiliary tank 19 is smaller than the tank body 17 and is formed to a size that allows it to enter the holding portion 174 of the tank body 17. The auxiliary tank 19 has a second bottom wall 191 and a second peripheral wall 192. The second bottom wall 191 is located at the bottom of the auxiliary tank 19 and has a rectangular shape extending in the front-rear and left-right directions. The second peripheral wall 192 is connected to the second bottom wall 191. The second peripheral wall 192 goes around the second bottom wall 191 in the circumferential direction along the outer periphery of the second bottom wall 191 and extends upward from the second bottom wall 191. As shown in Figures 8 and 9, the second peripheral wall 192 has a left side surface 192a located at the left end and a right side surface 192b located at the right end. The left side surface 192a and the right side surface 192b face each other in the left-right direction.

As shown in Figs. 5 and 6, the auxiliary tank 19 is detachably attached to the tank body 17. Specifically, as shown in Fig. 5, the auxiliary tank 19 enters the inside of the holding portion 174 from the entrance 175 with the second bottom wall 191 facing downward. The auxiliary tank 19 is then attached to the tank body 17 by being held by the holding portion 174. At this time, the upper part of the second bottom wall 191 of the auxiliary tank 19 protrudes upward from the tank body 17. Thus, the auxiliary tank 19 is attached to the tank body 17 and positioned at the front of the cleaning tank 7. At this time, the auxiliary tank 19 is located below the communication port 112 (see Fig. 4) of the top panel 11.

In addition, by being attached to the tank body 17, the auxiliary tank 19 is positioned above the storage chamber 170 in the tank body 17. In other words, the auxiliary tank 19 is positioned upstream of the storage chamber 170 in the flow direction of the detergent 300.

On the other hand, as shown by the white arrow in Figure 6, the auxiliary tank 19 can be removed from the tank body 17 by pulling it upward through the entrance 175, releasing it from the holding part 174. In this way, the auxiliary tank 19 removed from the tank body 17 can be taken out to the outside of the top panel 11, and ultimately to the outside of the movable body 5, through the communication opening 112 shown in Figure 4. Here, in this dishwasher 1, the auxiliary tank 19 is attached to the tank body 17 except when cleaning the auxiliary tank 19 or when performing maintenance on the tank body 17 and the supply device 13, etc.

As shown in Figures 8 and 9, the auxiliary tank 19 is provided with a refill port 19a, a guide portion 19b, a first tank filter 19c, and a second tank filter 19d. The first tank filter 19c and the second tank filter 19d are examples of the "filter" in the present invention.

The supply port 19a is located at the upper end of the second bottom wall 191, i.e., the upper end of the auxiliary tank 19, and opens in a generally rectangular shape. The second bottom wall 191, the second peripheral wall 192, and the supply port 19a form a bottomed cylindrical shape with an open upper end. As shown in FIG. 5, when the auxiliary tank 19 is attached to the tank body 17, the supply port 19a faces the communication port 112 shown in FIG. 3 from below and communicates with the communication port 112. In the auxiliary tank 19, detergent 300 is supplied to the inside through the supply port 19a.

The guide portion 19b is disposed in the auxiliary tank 19 and communicates with the supply port 19a. As shown in FIG. 8, the guide portion 19b is composed of a first guide wall 901, a first opening 902, a second guide wall 903, and a second opening 904.

The first guide wall 901 is integrally formed with the left side surface 192a of the first peripheral wall 92 and extends to the right, i.e., toward the right side surface 192b, inside the auxiliary tank 19. The first guide wall 901 guides the detergent 300 refilled from the refill port 19a toward the right side of the auxiliary tank 19. Here, the first guide wall 901 does not connect the left side surface 192a and the right side surface 192b in the left-right direction, and is separated from the right side surface 192b. The first guide wall 901 is inclined downward as it approaches the right side surface 192b. The angle at which the first guide wall 901 is inclined can be designed as appropriate.

The first opening 902 is located to the right of the first guide wall 901, between the first guide wall 901 and the right side surface 192b. In other words, the first guide wall 901 slopes downward toward the first opening 902. The first opening 902 allows the detergent 300 guided by the first guide wall 901 to flow below the first guide wall 901 inside the auxiliary tank 19.

The second guide wall 903 is disposed in the auxiliary tank 19 below the first guide wall 901 and the first opening 902, that is, downstream of the first guide wall 901 and the first opening 902 in the flow direction of the detergent 300. The second guide wall 903 is integrally formed with the right side surface 192b and extends leftward in the auxiliary tank 19. The second guide wall 903 guides the detergent 300 that has flowed through the first opening 902 toward the leftward in the auxiliary tank 19. Here, the second guide wall 903 does not connect the right side surface 192b and the left side surface 192a in the left-right direction in the auxiliary tank 19, and is separated from the left side surface 192a. In addition, the second guide wall 903 is inclined upward at an angle θ as it approaches the left side surface 192a. In other words, the second guide wall 903 is inclined upward at an angle θ with respect to a virtual straight line L that extends horizontally in the left-right direction. In this embodiment, the angle θ is set to approximately 1°. The value of the angle θ can be designed as appropriate. Also, in Figures 8 and 9, the inclination of the second guide wall 903 is exaggerated for ease of explanation.

The second opening 904 is located to the left of the second guide wall 903, between the second guide wall 903 and the left side surface 192a. In other words, the second guide wall 903 is inclined upward at an angle θ toward the second opening 904. The second opening 904 allows the detergent 300 guided by the second guide wall 903 to flow downward inside the auxiliary tank 19 beyond the second guide wall 903.

Here, the first opening 902 is located between the first guide wall 901 and the right side surface 192b, while the second opening 904 is located between the second guide wall 903 and the left side surface 192a. As a result, when the auxiliary tank 19 is viewed from above the movable body 5, the first opening 902 and the second opening 904 are arranged spaced apart in the left-right direction. More specifically, the second opening 904 is not located directly below the first opening 902, and the first opening 902 and the second opening 904 are arranged completely spaced apart in the left-right direction without any partial overlapping with each other in the up-down direction.

The first guide wall 901, the first opening 902, the second guide wall 903, and the second opening 904 form a labyrinth shape in the auxiliary tank 19 that snakes left and right while extending up and down, and connects to the supply port 19a and the storage chamber 170.

The first tank filter 19c and the second tank filter 19d are disposed in the auxiliary tank 19 downstream of the second opening 904 and thus the guide portion 19b in the flow direction of the detergent 300. As a result, the first tank filter 19c and the second tank filter 19d are positioned between the guide portion 19b and the storage chamber 170 when the auxiliary tank 19 is attached to the tank body 17. In other words, the first tank filter 19c and the second tank filter 19d are positioned downstream of the guide portion 19b and upstream of the storage chamber 170 in the flow direction of the detergent 300.

The first tank filter 19c is provided on the second peripheral wall 192. Here, the first tank filter 19c is provided on both the front and rear surfaces of the second peripheral wall 192. Meanwhile, the second tank filter 19d is provided on the second bottom wall 191. As a result, the second tank filter 19d is located downstream of the first tank filter 19c in the flow direction of the detergent 300.

The first tank filter 19c and the second tank filter 19d are formed in a mesh shape. As a result, the first tank filter 19c and the second tank filter 19d connect the inside of the auxiliary tank 19 to the storage chamber 170 when the auxiliary tank 19 is attached to the tank body 17. In this way, the detergent 300 that is refilled from the refill port 19a and flows through the guide part 19b passes through the first tank filter 19c and the second tank filter 19d and is stored in the storage chamber 170.

The first tank filter 19c and the second tank filter 19d are also capable of capturing foreign matter that enters the auxiliary tank 19 together with the detergent 300 as the detergent 300 passes through them. Examples of foreign matter include foodstuffs and leftovers that have fallen from the tableware TW1, as well as dirt adhering to the lid 112a and the area around the communication port 112 shown in FIG. 4. The first tank filter 19c or the second tank filter 19d may be omitted. Both the first tank filter 19c and the second tank filter 19d may be omitted.

As shown in Figs. 1 and 2, in this dishwasher 1, the movable body 5 is connected to a slide rail mechanism (not shown) provided inside the housing 3, and moves in the front-rear direction relative to the housing 3. This allows the movable body 5 to move between the stored position shown in Fig. 1 and the open position shown in Fig. 2. Specifically, the stored position shown in Fig. 1 is the position where the movable body 5 has moved to the rearmost position relative to the housing 3. When the movable body 5 is in the stored position, the entire cleaning space 7h of the cleaning tub 7 is located inside the housing 3. On the other hand, the open position shown in Fig. 2 is the position where the movable body 5 has moved to the frontmost position relative to the housing 3. When the movable body 5 is in the open position, the entire cleaning space 7h is located outside the housing 3, and the lid 112a is located outside the housing 3.

The lid member 35 also moves up and down inside the housing 3 in conjunction with the forward and backward movement of the movable body 5 relative to the housing 3. As a result, when the movable body 5 is in the stored position, as shown in Fig. 1, the lid member 35 moves downward to close the upper part of the cleaning space 7h. The lid member 35 moves above the cleaning tank 7 when the movable body 5 moves forward from the stored position, including when the movable body 5 is in the open position shown in Fig. 2. As a result, the lid member 35 opens the upper part of the cleaning space 7h and allows the movable body 5 to move forward.

To start washing dishes TW1 in this dishwasher 1, the user of the dishwasher 1 moves the movable body 5 from the stored position shown in Fig. 1 to the open position shown in Fig. 2. In this state, the user places dishes TW1 in the dish basket 70 in the washing space 7h. The user then operates the operation unit 40 and moves the movable body 5 to the stored position shown in Fig. 1. This causes the control unit C1 to perform various operational controls of the water supply solenoid valve 37, the supply device 13, etc. based on the control program, and starts the washing operation of the dishes TW1.

When the washing operation of the tableware TW1 is started, the water supply solenoid valve 37 opens, and water is supplied into the water storage chamber 71 by the water supply pipe P1 and the supply device 13. Furthermore, the detergent 300 stored in the storage chamber 170 is appropriately supplied into the water storage chamber 71 by the supply device 13. As a result, the tableware TW1 is washed with washing water in the washing space 7h for a predetermined time. Furthermore, while the tableware TW1 is being washed, the water level sensor detects the level of the washing water in the washing space 7h. Then, the control unit C1 appropriately controls the operation of the water supply solenoid valve 37, etc., based on the level of the washing water detected by the water level sensor.

After the washing of the tableware TW1 is completed, the washing water is drained through the drain pipe P2. In addition, the drying fan 77 is operated to dry the water droplets adhering to the tableware TW1. In this way, the washing operation of the tableware TW1 is completed.

In this way, in this dishwasher 1, the detergent 300 stored in the storage chamber 170, and therefore in the storage tank 15, is automatically supplied to the water storage chamber 71 by the supply device 13. Therefore, in this dishwasher 1, when washing the dishes TW1, the user does not need to pour the detergent 300 into the washing space 7h by himself. Also, in this dishwasher 1, the supply device 13 automatically supplies an appropriate amount of detergent 300 to the water storage chamber 71. These features make this dishwasher 1 highly convenient.

In addition, in this dishwasher 1, since the float 18 is provided in the storage chamber 170, the user can easily grasp the remaining amount of detergent 300 stored in the storage chamber 170. Specifically, when the remaining amount of detergent 300 stored in the storage chamber 170 is large, the float body 18a of the float 18 moves upward in the storage chamber 170 due to buoyancy. On the other hand, when the remaining amount of detergent 300 stored in the storage chamber 170 is low, the float body 18a moves downward in the storage chamber 170. As the float body 18a moves up and down in the storage chamber 170 in this way, the magnetism of the magnet 802 detected by the detection member changes. In this way, the control unit C1 displays the remaining amount of detergent 300 on the liquid crystal panel 41. In this way, in this dishwasher 1, the user can grasp the remaining amount of detergent 300 without directly looking inside the storage chamber 170. In this respect, the dishwasher 1 is also highly convenient.

When the remaining amount of detergent 300 stored in the storage chamber 170 becomes low, the user refills the storage chamber 170 with detergent 300. Specifically, the user moves the movable body 5 to the open position shown in FIG. 2. Then, the user displaces the lid body 112a to the open position. As a result, in the storage tank 15, the refill port 19a is in communication with the outside of the movable body 5 through the communication port 112. In this state, the user refills the auxiliary tank 19 with detergent 300 through the communication port 112 and the refill port 19a. Here, since the storage tank 15 and the supply device 13 in this dishwasher 1 are designed exclusively for liquid detergent 300, the user refills the liquid detergent 300.

The detergent 300 refilled into the auxiliary tank 19 from the refill port 19a flows through the guide portion 19b as shown in FIG. 8. That is, the detergent 300 flows rightward in the auxiliary tank 19 by the first guide wall 901. After flowing through the first opening 902, the detergent 300 flows leftward in the auxiliary tank 19 by the second guide wall 903, and then flows through the second opening 904, thereby reaching a position in the auxiliary tank 19 below the guide portion 19b. That is, the detergent 300 flows downward in the auxiliary tank 19, that is, toward the downstream side in the flow direction of the detergent 300, while meandering left and right through the guide portion 19b. Then, the detergent 300 flows from the auxiliary tank 19 into the tank body 17 while passing through the first tank filter 19c and the second tank filter 19d, and is stored in the storage chamber 170.

In this dishwasher 1, since the second guide wall 903 inclines upwards toward the second opening 904 in guide portion 19b, the flow speed of detergent 300 decreases to a certain degree at the second guide wall 903. That is, since the guide portion 19b is present between the supply port 19a and the storage chamber 170 in this dishwasher 1, the flow of detergent 300 supplied from the supply port 19a is hindered to a certain degree as it passes through guide portion 19b, compared to the case where detergent 300 flows directly from the supply port 19a to the storage chamber 170 .

However, in this dishwasher 1, if the detergent 300 supplied from the supply port is liquid, even if the flow is hindered to a certain extent while passing through the guide portion 19b, the detergent 300 can flow through the guide portion 19b, the first tank filter 19c, and the second tank filter 19d and into the storage chamber 170.

In addition, in this dishwasher 1, even if foreign matter enters the auxiliary tank 19 along with the detergent 300 when the detergent 300 is refilled from the refill port 19a, the foreign matter is captured by the first tank filter 19c and the second tank filter 19d as the detergent 300 passes through them. Therefore, in this dishwasher 1, it is difficult for foreign matter to enter the storage chamber 170.

In this dishwasher 1, the storage tank 15 and the supply device 13 are designed for the liquid detergent 300 as described above, but in addition to the liquid detergent 300, there are also solid detergents 300 in powder or tablet form. For this reason, a user may mistakenly supply solid detergent 300 through the supply port 19a. However, when solid detergent 300 is supplied, there is a risk that the supply port 172 of the storage tank 15 may become clogged, for example. In addition, in the supply device 13, there is a risk that the supply passage 13b or the connection passage 13c may become clogged, for example, and the device main body 13a may become abnormal in operation. In this way, there is a concern that the solid detergent 300 may cause the storage tank 15 and the supply device 13 to break down.

In this regard, in the dishwasher 1, even if solid detergent 300 is replenished, the storage tank 15 and the supply device 13 are less likely to break down. This effect will be specifically explained using the example of a case where powder detergent 300 is replenished.

As shown in FIG. 9, even if powdered detergent 300 is mistakenly refilled into the auxiliary tank 19 from the refill port 19a, the detergent 300 passes through the guide portion 19b and attempts to move toward the storage chamber 170. Here, in the guide portion 19b, since the first guide wall 901 is inclined downward toward the first opening 902, the detergent 300 flows toward the first opening 902 even if it is in powder form. Then, the detergent 300 falls from the first opening 902 onto the second guide wall 903. However, since the second guide wall 903 is inclined upward toward the second opening 904, the detergent 300 that has fallen onto the second guide wall 903 cannot flow to the second opening 904 against gravity. Therefore, the detergent 300 that has fallen from the first opening 902 to the second guide wall 903 accumulates on the second guide wall 903. As a result, the powder detergent 300 is barely able to pass through the guide portion 19b and is unable to reach the storage chamber 170.

In addition, as the powdered detergent 300 accumulates on the second guide wall 903, the detergent 300 clogs the guide section 19b in this dishwasher 1. This makes it easier for the user to notice that the powdered detergent 300 has been mistakenly refilled into the auxiliary tank 19 by sensing something unusual.

Furthermore, in the storage tank 15, the auxiliary tank 19 is detachable from the tank body 17. Therefore, if powdered detergent 300 is mistakenly refilled, the user can remove the auxiliary tank 19 from the tank body 17 as shown in FIG. 6. This makes it possible to conveniently remove the powdered detergent 300 present in the auxiliary tank 19 by cleaning the auxiliary tank 19.

In this way, in this dishwasher 1, even if powdered detergent 300 is supplied from the supply port 19a, the detergent 300 is unlikely to be stored in the storage chamber 170. Therefore, the powdered detergent 300 is unlikely to reach the supply device 13 from the storage tank 15, and the supply device 13 is unlikely to supply the powdered detergent 300 into the washing space 7h. Although not shown, the same is true when tablet-shaped detergent 300 is supplied from the supply port 19a. Furthermore, if the detergent 300 is tablet-shaped and becomes larger than the first opening 902, such detergent cannot pass through the first opening 902. Therefore, the user is more likely to sense something is wrong. Furthermore, such detergent 300 is not stored in the storage chamber 170.

Therefore, according to the dishwasher 1 of the embodiment, even if solid detergent 300 is mistakenly supplied to the auxiliary tank 19, failure of the storage tank 15 and the supply device 13 can be prevented.

As described above, in the dishwasher 1, the auxiliary tank 19 is detachable from the tank body 17. Therefore, even when liquid detergent 300 is being refilled, the auxiliary tank 19 can be removed from the tank body 17 and periodically cleaned to remove foreign matter captured by the first tank filter 19c and the second tank filter 19d. This makes it possible to keep the auxiliary tank 19, and therefore the storage tank 15, clean in the dishwasher 1.

Furthermore, in this dishwasher 1, the guide section 19b is composed of a first guide wall 901, a first opening 902, a second guide wall 903, and a second opening 904. This simplifies the configuration of the guide section 19b while allowing the guide section 19b to have a labyrinth shape that communicates with the refill port 19a and the storage chamber 170.

Here, because the first guide wall 901 is inclined downward toward the first opening 902, the detergent 300 can flow suitably to the first opening 902 by its own weight. Therefore, in this dishwasher 1, the obstruction of the flow of the detergent 300 in the guide section 19b can be minimized as much as possible, and the detergent 300 can be quickly replenished. In addition, in this dishwasher 1, a dedicated power for flowing the detergent 300 to the first opening 902 is not required.

On the other hand, the second guide wall 903 is inclined upward at an angle θ toward the second opening 904, and in this dishwasher 1, the angle θ is set to approximately 1°. Therefore, for the liquid detergent 300, it is possible to allow the second guide wall 903 to flow toward the second opening 904 while minimizing the decrease in flow rate when flowing through the second guide wall 903. However, as described above, for the solid detergent 300, it is possible to suitably prevent the second guide wall 903 from flowing toward the second opening 904.

Furthermore, the first opening 902 and the second opening 904 are arranged in a state where they are completely separated in the left-right direction without overlapping with each other in the up-down direction. Therefore, the detergent 300 that flows through the first opening 902 does not reach the second guide wall 903 and does not flow through the second opening 904.

As shown in FIG. 7, the tank body 17 is provided with an inlet 175 and a supply port 172, and when the tank body 17 is viewed from above the movable body 5, the inlet 175 and the supply port 172 are arranged so that they do not overlap with each other in the vertical direction and are completely separated in the horizontal direction. Therefore, in this dishwasher 1, even if solid detergent 300 is mistakenly supplied from the communication port 112 with the auxiliary tank 19 removed from the tank body 17, the detergent 300 can be effectively prevented from reaching the inlet 175 directly to the supply port 172 and ultimately the supply device 13.

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

For example, in the dishwasher 1 of the embodiment, the liquid detergent 300 is the "treatment agent" in the present invention, but this is not limited thereto, and liquid rinse may also be the "treatment agent" in the present invention.

In addition to the storage tank 15 and the supply device 13, a rinse tank for storing rinse and a rinse supply device for supplying rinse to the cleaning space 7h may be provided.

Furthermore, in the dishwasher 1 of the embodiment, the storage tank 15 has a tank body 17 and an auxiliary tank 19. However, this is not limited to the above, and the storage tank 15 may be configured without the auxiliary tank 19 by using the inlet 175 of the tank body 17 as the "supply port" in the present invention and providing a guide portion 19b between the inlet 175 and the storage chamber 170.

In addition, in the dishwasher 1 of the embodiment, the second guide wall 903 is inclined upward at an angle θ toward the second opening 904. However, this is not limited to this, and the second guide wall 903 may extend horizontally in the left-right direction toward the second opening 904. In addition, the second guide wall 903 may be inclined downward at a predetermined angle toward the second opening 904.

Furthermore, the first tank filter 19c and the second tank filter 19d may be disposed between the supply port 19a and the guide portion 19b, i.e., downstream of the supply port 19a in the flow direction of the detergent 300 and upstream of the first guide wall 901 in the flow direction of the detergent 300.

The first tank filter 19c may be provided downstream of the supply port 19a and upstream of the guide portion 19b, while the second tank filter 19d may be provided downstream of the guide portion 19b and upstream of the storage chamber 170.

Furthermore, the first guide wall 901 may be formed by two plate materials spaced apart in the left-right direction, and the first opening 902 may be disposed between the two plate materials. The same applies to the second guide wall 903 and the second opening 904.

In addition, the guide portion 19b may be labyrinth-shaped within the auxiliary tank 19, snaking vertically and communicating with the supply port 19a and the storage chamber 170.

Furthermore, in the dishwasher 1 of the embodiment, the tank body 17 is fixed to the front of the washing tub 7. However, this is not limited to the above, and the tank body 17 may be fixed to the right or left side of the washing tub 7. In this case, in the tank body 17, the inlet 175 and the supply port 172 may be arranged to be spaced apart in the front-rear direction when the tank body 17 is viewed from above the movable body 5. The same applies to the first opening 902 and the second opening 904.

In addition, in the dishwasher 1 of the embodiment, as long as the inlet 175 and the supply port 172 are arranged spaced apart in the left-right direction when the tank body 17 is viewed from above the movable body 5, the inlet 175 and the supply port 172 may overlap each other partially in the up-down direction. Even in this case, when the auxiliary tank 19 is removed from the tank body 17 and solid detergent 300 is mistakenly replenished through the communication port 112, it is possible to a certain extent to prevent the detergent 300 from reaching the supply port 172 directly from the inlet 175. The same applies to the first opening 902 and the second opening 904.

Furthermore, the dishwasher 1 of the embodiment is not limited to being incorporated into the system kitchen 100, but may be independent of the system kitchen 100.

The present invention can be used in dishwashers, dishwasher-dryers, kitchen equipment, etc.
