As shown in FIG. 5, the second connection terminal 25 is connected to the first connection terminal 174a of the connection portion 174 by accommodating the tank body 15a and the storage tank 15 in the case 17. As a result, the first and second electrodes 21 and 23 are electrically connected to the connecting portion 174. In this way, the first and second electrodes 21 and 23 are energized inside the tank body 15a, and the remaining amount of the rinse 300 stored inside the tank body 15a is based on the change in the magnitude of the electric resistance value between the first and second electrodes 21 and 23. Is detected. The remaining amount detection device 200 is composed of the first and second electrodes 21, 23, the connection unit 174, and the control unit C1.

As shown in FIGS. 5 and 6, the tank cover 15b is arranged on the upper part of the tank body 15a. The tank cover 15b is made of resin like the tank body 15a. The tank cover 15b is formed with a supply port 153, a first recess 154, a second recess 155, a first engagement hole 156, and a second engagement hole 157. The supply port 153 penetrates the tank cover 15b in the vertical direction. The first recess 154 and the second recess 155 are each recessed in the tank cover 15b. The user's finger can enter the first recess 154 and the second recess 155. The first engaging hole 156 is formed at the left end of the tank cover 15b, and the second engaging hole 157 is formed at the right end of the tank cover 15b.

The tank cover 15b is removable from the upper part of the tank body 15a. Specifically, the tank cover 15b is formed by engaging the first and second engaging holes 156 and 157 with the first and second engaging claws 152a and 152b of the tank body 15a, respectively. Attached to the top. Then, by attaching the tank cover 15b to the upper part of the tank body 15a in this way, the supply port 153 communicates with the inside of the tank body 15a. On the other hand, the tank cover 15b can be removed from the tank body 15a by disengaging the first and second engaging claws 152a and 152b from the first and second engaging holes 156 and 157. ..

Further, the lid 29 is attached to the tank cover 15b via the first attachment pin 27. The lid 29 swings around the first swing axis X1 with the axis of the first mounting pin 27 as the first swing axis X1 with respect to the tank cover 15b, so that the lid 29 is in the closed position shown in FIG. And, it is possible to displace to the open position shown in FIG. The lid 29 closes the supply port 153 by being in the closed position shown in FIG. On the other hand, the lid 29 opens the supply port 153 by being in the open position shown in FIG.

As shown in FIGS. 1 and 2, in the dishwasher 1, the moving body 5 is connected to a slide rail mechanism (not shown) provided inside the housing 3, with respect to the housing 3. It is moving in the front-back direction. As a result, the moving body 5 can move between the storage position shown in FIG. 1 and the open position shown in FIG. Specifically, the storage position shown in FIG. 1 is the position where the moving body 5 has moved most rearward with respect to the housing 3. When the moving body 5 is in the storage position, the cleaning space 7h of the cleaning tank 7 is entirely located inside the housing 3. On the other hand, the open position shown in FIG. 2 is the position where the moving body 5 has moved most forward with respect to the housing 3. When the moving body 5 is in the open position, the entire cleaning space 7h is located outside the housing 3.

Further, the lid member 35 moves up and down inside the housing 3 in conjunction with the front-back direction of the moving body 5 with respect to the housing 3. As a result, as shown in FIG. 1, the lid member 35 moves downward and closes the upper part of the cleaning space 7h when the moving body 5 is in the storage position. Then, the lid member 35 moves above the cleaning tank 7 by moving the moving body 5 forward from the storage position, including when the moving 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 moving body 5 to move forward.

In the dishwasher 1 configured as described above, the storage tank 15 can be attached to and detached from the washing tank 7 by moving in the vertical direction, which is the attachment / detachment direction. Specifically, when attaching the storage tank 15 to the washing tank 7, the user makes the connection port 150 of the storage tank 15 face downward. Then, in this state, the storage tank 15 is moved downward from the attachment port 112 shown in FIG. 3, and the storage tank 15 is housed in the case 17 shown in FIG. As a result, in the storage tank 15, the first and second electrodes 21 and 23 are electrically connected to the connection portion 174 as described above. Further, as shown in FIG. 9, in the case 17, the connection port 150 is held by the contact port 170 while entering the upper part of the contact port 170. In this way, the connection port 150 is connected to the connection port 170, and the storage tank 15 is held in the case 17. As a result, the storage tank 15 is attached to the front part of the washing tank 7 through the case 17. Further, by attaching the storage tank 15 to the front portion of the cleaning tank 7 in this way, the tank cover 15b is located in the attachment port 112. Thus, as shown in FIGS. 1 to 3, in the moving body 5, the storage tank 15 is arranged outside the cleaning space 7h and between the front panel 9 and the cleaning tank 7.

Here, in the process of the connection port 150 entering the upper part of the communication port 170, in the outflow prevention mechanism 19, as shown in FIG. 9, the valve body 19c is pressed by the pressing pin 130 of the supply passage 13c through the pressed portion 198. To. As a result, the valve body 19c moves upward while resisting the urging force of the coil spring 19d, and opens the second outlet 197. In this way, the connection port 150 and the supply passage 13c communicate with each other through the communication port 170. Therefore, the rinse 300 stored inside the tank body 15a flows from the connection port 150 to the supply passage 13c via the supply passage 13c while passing through the filter net 162 of the tank filter 16. In this way, the rinse 300 is supplied to the supply device 13 from the storage tank 15 attached to the front portion of the cleaning tank 7.

On the other hand, when removing the storage tank 15 from the cleaning tank 7, the user moves the moving body 5 forward from the storage position, including the open position shown in FIG. 2, while the user grips the grip portion 111. , The tank cover 15b is exposed to the outside of the housing 3. Then, the user pulls up the storage tank 15 upward from the mounting port 112 while grasping the tank cover 15b through the first and second recesses 154 and 155. As a result, as shown in FIG. 10, in the case 17, the connection between the connection port 150 and the contact port 170 is released, and the holding of the storage tank 15 by the case 17 is released. Thus, as shown by the white arrows in FIGS. 2 and 6, the storage tank 15 moves upward with respect to the case 17, and the storage tank 15 is removed from the washing tank 7. Then, as shown in FIG. 6, the connection between the first and second electrodes 21 and 23 and the connecting portion 174 is released, and the energization of the first and second electrodes 21 and 23 is stopped.

Here, as shown in FIG. 10, the storage tank 15 moves upward with respect to the case 17, so that the valve body 19c is separated from the pressing pin 130 in the outflow prevention mechanism 19. As a result, the valve body 19c moves downward due to the urging force of the coil spring 19D and comes into contact with the valve seat 195. As a result, the valve body 19c closes the second outlet 197. In this way, in the dishwasher 1, when the storage tank 15 is removed from the washing tank 7, the rinse 300 in the tank body 15a is less likely to flow out from the connection port 150.

Then, when the dishwasher 1 starts washing the tableware TW1, the user moves the moving body 5 from the accommodation position shown in FIG. 1 to the open position shown in FIG. In this state, the user accommodates the tableware TW1 in the tableware basket 70 in the washing space 7h. If the storage tank 15 is not attached to the washing tank 7, the user attaches the storage tank 15 to the washing tank 7 as described above. After that, the user operates the operation unit 40 and moves the moving body 5 to the accommodation position shown in FIG. As a result, the control unit C1 controls various operations of the water supply solenoid valve 37, the supply device 13, and the like based on the control program, and starts the washing operation of the tableware TW1.

When the washing operation of the tableware TW1 is started, the water supply solenoid valve 37 is opened, and water is supplied into the water storage chamber 71 by the water supply pipe P1 and the supply device 13. Further, the detergent is appropriately charged into the water storage chamber 71 by the detergent automatic charging device. As a result, the tableware TW1 is washed with the washing water in the washing space 7h in a predetermined time. Further, while the tableware TW1 is being washed, the water level sensor detects the water 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 and the like based on the water 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 by the drain pipe P2. Then, after washing the tableware TW1, the tableware TW1 is rinsed. At this time, the supply device 13 supplies the treated water containing the rinse 300 supplied from the storage tank 15 into the water storage chamber 71. As a result, the tableware TW1 is rinsed and treated with treated water. After the treatment with the treated water is completed, the treated water is drained by the drain pipe P2, and the water droplets adhering to the tableware TW1 are dried by the drying fan 77. In this way, the washing operation of the tableware TW1 is completed. Here, since the drying time of the water droplets adhering to the tableware TW1 is accelerated by the rinse 300, spots are less likely to occur on the tableware TW1 after drying.

As described above, in the dishwasher 1, the rinse 300 stored in the storage tank 15 is automatically supplied to the water storage chamber 71 together with the water by the supply device 13. Therefore, in this dishwasher 1, in order to prevent spots from being generated on the tableware TW1 after drying, the user himself supplies the rinse 300 and the treated water containing the rinse 300 to the water storage chamber 71, and eventually to the washing space 7h. You don't have to. As a result, in this dishwasher 1, it is possible to easily prevent the generation of spots on the tableware TW1. After the washing operation of the tableware TW1 is completed, the user can take out the tableware TW1 from the washing space 7h by moving the moving body 5 to the open position, and the tableware TW1 is continuously housed in the washing space 7h. It can also be stored.

Further, in the dishwasher 1, the first and second electrodes 21 and 23 are provided on the tank body 15a of the storage tank 15. Then, the first and second electrodes 21 and 23 detect the remaining amount of the rinse 300 stored in the tank body 15a while the storage tank 15 is attached to the washing tank 7. Specifically, as shown in FIG. 7A, the remaining amount of the rinse 300 stored in the tank body 15a is large, and both the first electrode 21 and the second electrode 23 are immersed in the rinse 300. In the state, the electric resistance value between the first electrode 21 and the second electrode 23 becomes the smallest. On the other hand, the remaining amount of the rinse 300 stored in the tank body 15a decreases, and only the first electrode 21 begins to be immersed in the rinse 300, so that the electric resistance between the first electrode 21 and the second electrode 23 The value starts to increase. Then, as shown in FIG. 7B, the remaining amount of the rinse 300 stored in the tank body 15a is almost zero, including the state where only the tip of the first electrode 21 is immersed in the rinse 300. Therefore, the electric resistance value between the first electrode 21 and the second electrode 23 becomes maximum. Such changes in the electrical resistance values of the first and second electrodes 21 and 23 based on the remaining amount of the rinse 300 are transmitted to the control unit C1 through the connection unit 174. As a result, the control unit C1 causes the liquid crystal panel 41 to display the remaining amount of the rinse 300 detected by the first and second electrodes 21 and 23. As a result, the user is aware of the remaining amount of the rinse 300 stored in the storage tank 15, and replenishes the rinse 300 as necessary. The control unit C1 may always display the change in the remaining amount of the rinse 300 based on the change in the electric resistance values of the first and second electrodes 21 and 23 on the liquid crystal panel 41, and the first and second electrodes 21 and 23 may be displayed. When the electric resistance value of the above exceeds a preset threshold value, the remaining amount of the rinse 300 may be displayed on the liquid crystal panel 41.

Here, in the dishwasher 1, the storage tank 15 is removable from the washing tank 7. Therefore, the user can replenish the rinse 300 in the tank body 15a through the supply port 153 of the tank cover 15b with the storage tank 15 removed from the washing tank 7. As a result, the user can replenish the rinse 300 to the storage tank 15 at a place away from the washing tank 7 and the housing 3. Therefore, it is easier to perform the replenishment work of the rinse 300 as compared with the case where the replenishment work of the rinse 300 is performed with the storage tank 15 attached to the washing tank 7. Therefore, in this dishwasher 1, it is possible to prevent a part of the rinse 300 from spilling onto the cleaning tank 7, the upper panel 11, the housing 3, and the like during the replenishment work of the rinse 300. ..

In this dishwasher 1, the attachment / detachment direction when attaching / detaching the storage tank 15 to / from the washing tank 7 is the vertical direction, and the front-back direction when moving the moving body 5 between the storage position and the open position is It's different. Therefore, in the dishwasher 1, when the storage tank 15 is attached to and detached from the washing tank 7, the moving body 5 is prevented from unexpectedly moving back and forth with respect to the housing 3. Further, in the dishwasher 1, by moving the moving body 5 back and forth with respect to the housing 3, the storage tank 15 already attached to the washing tank 7 is suddenly removed from the washing tank 7. It is also prevented from being stolen.

Therefore, in the dishwasher 1 of the first embodiment, in the configuration having the storage tank 15 for storing the rinse 300, the user can suitably replenish the storage tank 15 with the rinse 300.

In particular, in this dishwasher 1, the storage tank 15 attached to the washing tank 7 is located between the front panel 9 and the front part of the washing tank 7. This makes it easier for the user to attach / detach the storage tank 15 to / from the washing tank 7 in the dishwasher 1 as compared with the configuration in which the storage tank 15 is detachably attached to the rear part of the washing tank 7, for example. There is. Further, in the dishwasher 1, when the storage tank 15 is attached to and detached from the washing tank 7, it is not always necessary to move the moving body 5 significantly to the front of the housing 3. In this respect as well, the dishwasher 1 makes it possible to easily attach / detach the storage tank 15 to / from the washing tank 7, and the user can suitably replenish the storage tank 15 with the rinse 300. It has become.

Further, in the dishwasher 1, when the storage tank 15 is removed from the washing tank 7, the outflow prevention mechanism 19 prevents the storage tank 15 from flowing out from the rinse 300 from the connection port 150. Therefore, the user causes the rinse 300 to flow out from the connection port 150 when the storage tank 15 is replenished with the rinse 300 or when the storage tank 15 for which the rinse 300 has been replenished is attached to the cleaning tank 7. You don't have to worry about it. Therefore, in the dishwasher 1, it is possible to suitably perform the replenishment work of the rinse 300 and the attachment work of the storage tank 15.

Further, in the dishwasher 1, the first and second electrodes 21 and 23 detect the remaining amount of the rinse 300 stored in the tank body 15a based on the change in the electric resistance value between the first and second electrodes 21 and 23. As a result, in the dishwasher 1, the remaining amount of the rinse 300 can be detected with high accuracy by the first and second electrodes 21 and 23. Further, since the remaining amount of the rinse 300 detected by the first and second electrodes 21 and 23 is displayed on the liquid crystal panel 41 to notify the user, the user can use the inside of the storage tank 15 through the supply port 153. It is not necessary to visually check the remaining amount of the rinse 300. For these reasons, the dishwasher 1 is highly convenient.

Further, in the dishwasher 1, the case 17 is fixed to the front part of the washing tank 7, and the storage tank 15 is attached to and detached from the washing tank 7 through the storage and removal of the storage tank 15 in the case 17. As a result, the storage tank 15 can be easily attached to and detached from the cleaning tank 7 as compared with the case where the storage tank 15 is directly attached to and detached from the cleaning tank 7. Further, since the storage tank 15 is housed in the case 17, in the dishwasher 1, even if a part of the rinse 300 is attached to the surface of the tank body 15a, the rinse 300 is a storage space. It is possible to prevent the 90 and the housing 3 from spilling inside.

Further, in the dishwasher 1, a tank filter 16 is provided on the tank body 15a of the storage tank 15. Therefore, in the dishwasher 1, even if a foreign substance enters the tank body 15a when the rinse 300 is replenished, it is difficult for the foreign substance to be distributed to the supply device 13 together with the rinse 300.

Further, in the dishwasher 1, in the storage tank 15, the tank cover 15b is removable from the tank body 15a. Therefore, in the dishwasher 1, it is easy to wash the inside of the tank body 15a as needed, and it is also easy to wash or replace the tank filter 16. Further, since the tank cover 15b is provided with a lid 29 capable of opening and closing the replenishment port 153, it is difficult for foreign matter or the like to enter the inside of the tank body 15a from the replenishment port 153. Further, in this dishwasher 1, it is possible to suitably prevent the rinse 300 stored in the tank body 15a from leaking to the outside from the supply port 153 due to vibration or the like during washing of the tableware TW1. ..

(Example 2)
As shown in FIGS. 11 and 12, the dishwasher 1 of the second embodiment includes a remaining amount detecting device 500 instead of the remaining amount detecting device 200. The remaining amount detecting device 500 has a float 50, a float detecting unit 51, and a control unit C1. Further, in the dishwasher 1, the first switch chamber 175a is formed on the bottom wall 17a of the case 17, and the second switch chamber 175b is formed on the peripheral wall 17b.

The float 50 is provided in the tank body 15a. As shown in FIGS. 13 and 14, the float 50 is made of resin and has a float main body 50a, a float cover 50b, and a shaft body 50c. The float body 50a is formed in a bottomed tubular shape. Inside the float body 50a, an air chamber 501 for suspending the float body 50a in the rinse 300 is formed. Further, a magnet 502 is provided inside the float body 50a. The magnet 502 is an example of the "magnetic material" in the present invention. The magnet 502 is a public product and is fixed inside the float body 50a.

The float cover 50b is attached to the float body 50a. As a result, the float cover 50b secures the airtightness inside the float body 50a including the air chamber 501, and prevents the rinse 300 from entering the inside of the float body 50a. The shaft body 50c is formed in a substantially rectangular shape. In FIG. 13, the tank filter 16 is not shown for the sake of simplicity.

As shown in FIGS. 11 and 12, the shaft body 50c is connected to the float body 50a at one end in the axial direction, that is, at the end on the float body 50a side. The other end of the shaft body 50c in the axial direction extends away from the float body 50a.

The float detection unit 51 includes a first reed switch 51a and a second reed switch 51b. The first and second reed switches 51a and 51b are public products and can detect the magnetism of the magnet 502. The first reed switch 51a is held in the first switch chamber 175a. The second reed switch 51b is held in the second switch chamber 175b. In this way, the first and second reed switches 51a and 51b are provided on the bottom wall 17a and the peripheral wall 17b, respectively. Further, the first and second reed switches 51a and 51b are electrically connected to the control unit C1.

Further, as shown in FIGS. 13 and 14, in the dishwasher 1, a first connection portion 158 and a second connection portion 159 are formed with respect to the tank cover 15b. The first connection portion 158 and the second connection portion 159 are connected to the tank cover 15b at the upper ends and extend downward. The lower ends of the first connecting portion 158 and the second connecting portion 159 are connected to the other end in the axial direction of the shaft body 50c by the second mounting pin 60. As a result, as shown in FIGS. 11 and 12, in the tank body 15a, the float 50 has the axis of the second mounting pin 60 as the second swing axis X2, and around the second swing axis X2. It is possible to swing. The other configurations of the dishwasher 1 are the same as those of the dishwasher of the first embodiment, and the same configurations are designated by the same reference numerals and detailed description of the configurations will be omitted.

In the dishwasher 1, in the float 50, the float body 50a floats on the rinse 300 stored in the tank body 15a while maintaining the state of being connected to the shaft body 50c. Therefore, the float 50 swings around the second swing axis X2 in the tank body 15a. Here, the position of the float body 50a in the tank body 15a changes due to a change in the remaining amount of the rinse 300 stored in the tank body 15a. That is, as shown in FIG. 11, when the remaining amount of the rinse 300 is low, the float body 50a moves below the tank body 15a and approaches the bottom 151. On the other hand, as shown in FIG. 12, when the remaining amount of the rinse 300 is large, the float main body 50a moves above the tank main body 15a and approaches the peripheral wall portion 152.

Then, when the remaining amount of the rinse 300 is small and the float body 50a approaches the bottom 151, the magnetism of the magnet 502 detected by the first reed switch 51a becomes large, while the magnet 502 detected by the second reed switch 51b increases. The magnetism becomes smaller. On the contrary, when the remaining amount of the rinse 300 is large and the float body 50a approaches the peripheral wall portion 152, the magnetism of the magnet 502 detected by the first reed switch 51a becomes smaller, while the magnet detected by the second reed switch 51b becomes smaller. The magnetism of the 502 becomes large. In this way, the float detection unit 51 detects the position of the float body 50a in the tank body 15a based on the magnetic magnitude of the magnet 502 detected by the first and second reed switches 51a and 51b. Then, the float detecting unit 51 and the remaining amount detecting device 500 can detect the remaining amount of the rinse 300 in the tank body 15a based on the detected position of the float body 50a. In this way, even in the dishwasher 1, the remaining amount of the rinse 300 can be detected with high accuracy by the remaining amount detecting device 500. Further, also in this dishwasher 1, the remaining amount of the rinse 300 detected by the remaining amount detecting device 500 is displayed on the liquid crystal panel 41.

Further, in the dishwasher 1, the float 50 is connected to the tank cover 15b by connecting the shaft body 50c to the lower ends of the first and second connecting portions 158 and 159. This facilitates the attachment of the float 50. Further, as shown in FIG. 14, in the dishwasher 1, by removing the tank cover 15b from the tank body 15a, the float 50 can also be taken out from the tank body 15a. Therefore, in the dishwasher 1, the float 50 can be easily replaced and washed. Other actions in the dishwasher 1 are the same as those in the dishwasher 1 of the first embodiment.
