The 1 st holding body 19a includes: the spring seat 191, the 1 st engaging portion 192, the insertion hole 193, and the 1 st outflow port 194. The spring seat 191 is located substantially at the center in the 1 st holding body 19 a. The 1 st engaging portion 192 is formed integrally with the spring seat 191 on the outer periphery of the spring seat 191, and extends upward from the spring seat 191. The insertion hole 193 and the 1 st outflow port 194 penetrate the 1 st holding body 19a in the vertical direction. The insertion hole 193 is located at the center of the spring seat 191. On the other hand, the 1 st outflow port 194 is located between the spring seat 191 and the 1 st engagement portion 192. The 1 st holding body 19a is provided inside the connection port 150 in a state where the 1 st engaging portion 192 enters the inside of the cartridge main body 15 a. Accordingly, the 1 st engaging portion 192 engages with the engaging projection 163 of the filter frame 161 to fix the cartridge filter 16 to the lower portion of the cartridge main body 15 a.

The 2 nd holding body 19b is formed with a valve seat 195, a 2 nd engaging portion 196, and a 2 nd outflow port 197. The valve seat 195 is located at the lower end of the 2 nd holding body 19 b. The 2 nd engaging portion 196 is formed integrally with the valve seat 195 on the outer periphery of the valve seat 195, and extends upward from the valve seat 195. The 1 st outflow port 194 is located at the center of the valve seat 195 and vertically penetrates the 2 nd holding body 19 b. The 2 nd holding body 19b is provided inside the connection port 150 and is positioned below the 1 st holding body 19 a. Then, the 2 nd engaging portion 196 is engaged with the 1 st holding body 19a, whereby the 2 nd holding body 19b is assembled to the 1 st holding body 19 a.

The valve element 19c is disposed between the 1 st holding body 19a and the 2 nd holding body 19b in a state of being inserted through the insertion hole 193 of the 1 st holding body 19 a. The valve element 19c is vertically movable between the 1 st holding body 19a and the 2 nd holding body 19 b. Accordingly, as shown in fig. 9, the 2 nd outlet 197 can be opened by separating the valve element 19c upward from the valve seat 195 of the 2 nd holding body 19 b. As shown in fig. 10, the 2 nd outlet 197 can be closed by the valve element 19c abutting against the valve seat 195. Further, a pressed portion 198 is provided at the lower end of the valve body 19 c. The pressed portion 198 can abut against the pressing pin 130.

The coil spring 19d is provided between the spring seat 191 of the 1 st retaining body 19a and the valve body 19 c. The coil spring 19d biases the valve body 19c toward the valve seat 195. The outflow prevention mechanism 19 may have another configuration.

As shown in fig. 5 and 6, a 1 st engaging claw 152a and a 2 nd engaging claw 152b are formed at the upper end of the peripheral wall portion 152. As shown in fig. 7, the 1 st electrode 21 and the 2 nd electrode 23 are attached to the peripheral wall portion 152. The 1 st electrode 21 and the 2 nd electrode 23 are examples of the "electrode" in the present invention.

The 1 st and 2

nd electrodes

21 and 23 are held by the holding member 24 in a state of being separated in the front-rear direction, and extend downward in the inside of the cartridge main body 15 a. Here, the 1 st electrode 21 and the 2 nd electrode 23 are different in length in the up-down direction. Specifically, the 1 st electrode 21 extends to a position close to the bottom 151 of the cartridge body 15 a. On the other hand, the 2 nd electrode 23 is formed shorter than the 1 st electrode 21. The holding member 24 holds the 1 st and 2

nd electrodes

21 and 23 in the cartridge main body 15a, and seals between the peripheral wall portion 152 and the 1 st and 2

nd electrodes

21 and 23.

As shown in fig. 5 and 6, the 1 st and 2

nd electrodes

21 and 23 include: and 2 nd connection terminals 25 projecting to the outside of the peripheral wall portion 152. As shown in fig. 5, when the cartridge main body 15a and the storage case 15 are accommodated in the case 17, the 2 nd connection terminal 25 is connected to the 1 st connection terminal 174a of the connection portion 174. Accordingly, the 1 st and 2

nd electrodes

21 and 23 are electrically connected to the connection portion 174. In this way, the 1 st and 2

nd electrodes

21 and 23 are energized inside the cartridge main body 15a, and the remaining amount of the rinse agent 300 remaining inside the cartridge main body 15a can be monitored based on the magnitude change of the resistance values therebetween. The remaining-amount monitoring device 200 is configured by the 1 st and 2

nd electrodes

21 and 23, the connection unit 174, and the control unit C1.

As shown in fig. 5 and 6, the box cover 15b is disposed on the upper portion of the box main body 15 a. The case cover 15b is made of resin as in the case main body 15 a. The lid 15b has: supply port 153, 1 st recess 154, 2 nd recess 155, 1 st engagement hole 156, and 2 nd engagement hole 157. The supply port 153 penetrates the cover 15b in the vertical direction. The 1 st recess 154 and the 2 nd recess 155 are recessed in the box cover 15 b. The user's fingers can enter into the 1 st recess 154 and the 2 nd recess 155. The 1 st engaging hole 156 is formed at the left end of the cover 15b, and the 2 nd engaging hole 157 is formed at the right end of the cover 15 b.

The box cover 15b is detachable from the upper part of the box main body 15 a. Specifically, the 1 st and 2

nd engaging holes

156 and 157 are engaged with the 1 st and 2

nd engaging claws

152a and 152b of the cartridge body 15a, respectively, so that the cartridge cover 15b is attached to the upper portion of the cartridge body 15 a. By attaching the cover 15b to the upper portion of the case main body 15a in this manner, the supply port 153 communicates with the inside of the case main body 15 a. On the other hand, the 1 st and 2

nd engagement claws

152a and 152b are disengaged from the 1 st and 2 nd engagement holes 156 and 157, whereby the cover 15b can be detached from the case main body 15 a.

In addition, a lid 29 is attached to the lid 15b via the 1 st attaching pin 27. The lid 29 can be moved to the closed position shown in fig. 5 and the open position shown in fig. 6 by swinging about the 1 st swing axis X1 about the axis of the 1 st mounting pin 27 as the 1 st swing axis X1 with respect to the box cover 15 b. The lid body 29 closes the refill port 153 by being in the closed position shown in fig. 5. On the other hand, the lid 29 is in the open position shown in fig. 6, and thereby opens the refill port 153.

As shown in fig. 1 and 2, in the dish washing machine 1, the moving body 5 is coupled to a slide rail mechanism (not shown) provided inside the casing 3 and moves in the front-rear direction with respect to the casing 3. Accordingly, the movable body 5 can move between the storage position shown in fig. 1 and the open position shown in fig. 2. Specifically, the storage positions shown in fig. 1 are: the movable body 5 moves to the rearmost position with respect to the casing 3. With the moving body 5 in the storage position, the cleaning space 7h of the cleaning tank 7 is completely located inside the cabinet 3. On the other hand, the open position shown in fig. 2 is: the movable body 5 moves to the frontmost position with respect to the casing 3. With the moving body 5 in the open position, the cleaning space 7h is completely located outside the cabinet 3.

The cover member 35 moves vertically inside the casing 3 in conjunction with the moving body 5 in the front-rear direction with respect to the casing 3. Accordingly, as shown in fig. 1, when the moving body 5 is at the storage position, the cover member 35 moves downward to close the upper portion of the cleaning space 7 h. Then, the cover member 35 moves upward of the cleaning tank 7 by moving the movable body 5 to a position forward of the storage position including when the movable body 5 is at the open position shown in fig. 2. Accordingly, the cover member 35 opens the upper portion of the cleaning space 7h and allows the moving body 5 to move forward.

According to the dish washing machine 1 configured as described above, the storage box 15 can be attached to the washing tub 7 by moving in the vertical direction, which is the attaching and detaching direction. Specifically, when the storage box 15 is mounted to the washing tub 7, the user brings the connection port 150 of the storage box 15 into a downward state. In this state, magazine 15 is moved downward from mounting opening 112 shown in fig. 3, and magazine 15 is accommodated in case 17 shown in fig. 5. Accordingly, in the storage case 15, as described above, the 1 st and 2

nd electrodes

21 and 23 are electrically connected to the connection portion 174. As shown in fig. 9, in housing 17, connection port 150 enters the upper portion of communication port 170 and is held by communication port 170. Thus, the following steps are performed: connection port 150 is connected to communication port 170, and storage box 15 is held in housing 17. As a result, the storage box 15 is attached to the front of the sink 7 through the case 17. In addition, the storage box 15 is mounted on the front portion of the sink 7 such that the box cover 15b is located at a position inside the mounting opening 112. As described above, in the moving body 5, as shown in fig. 1 to 3, the storage box 15 is disposed between the front panel 9 and the cleaning tank 7 outside the cleaning space 7 h.

Here, 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 by the pressed portion 198 while the connection port 150 enters the upper portion of the communication port 170. Accordingly, the valve body 19c is moved upward against the urging force of the coil spring 19d, and the 2 nd outlet 197 is opened. Thus, connection port 150 communicates with supply passage 13c through communication port 170. As a result, the rinse agent 300 stored in the cartridge main body 15a passes through the filter mesh 162 of the cartridge filter 16 and flows through the supply passage 13c from the connection port 150 via the supply passage 13 c. Thus, the rinsing agent 300 is supplied from the storage box 15 installed at the front of the cleaning tank 7 to the supply device 13.

On the other hand, when detaching the storage box 15 from the washing tub 7, the user grips the grip portion 111, and the user moves the moving body 5 to a position forward of the storage position including the open position shown in fig. 2, so that the box cover 15b is exposed to the outside of the box body 3. Then, the user holds the box cover 15b by the first and

second recesses

154 and 155, and pulls up the storage box 15 from the mounting opening 112. Accordingly, as shown in fig. 10, the connection between the connection port 150 and the communication port 170 is released in the case 17, and the holding of the case 15 by the case 17 is released. As shown by white arrows in fig. 2 and 6, the storage box 15 is thus moved upward relative to the housing 17, and the storage box 15 is detached from the wash bowl 7. Then, as shown in fig. 6, the connection between the 1 st and 2

nd electrodes

21 and 23 and the connection portion 174 is released, and the current supply to the 1 st and 2

nd electrodes

21 and 23 is stopped.

Here, as shown in fig. 10, the cartridge 15 moves upward relative to the case 17, and the valve element 19c moves away from the pressing pin 130 in the outflow prevention mechanism 19. Accordingly, the valve element 19c moves downward by the biasing force of the coil spring 19D and comes into contact with the valve seat 195. As a result, the valve body 19c closes the 2 nd outflow port 197. As described above, according to dishwasher 1, rinse agent 300 in cartridge main body 15a is less likely to flow out from connection port 150 in a state where storage cartridge 15 is detached from washing tub 7.

In the dishwasher 1, when the user starts washing the dishes TW1, the user moves the movable body 5 from the storage position shown in fig. 1 to the open position shown in fig. 2. In this state, the user stores the dish TW1 in the dish basket 70 in the washing space 7 h. In addition, in the case where the storage box 15 is not attached to the washing tub 7, the user attaches the storage box 15 to the washing tub 7 as described above. Thereafter, the user operates the operation unit 40 and moves the moving body 5 to the storage position shown in fig. 1. Accordingly, controller C1 controls various operations of water supply solenoid valve 37, supply device 13, and the like based on the control program, and starts the washing operation of tableware TW 1.

When the washing operation of tableware TW1 is started, water supply solenoid valve 37 is opened, and water is supplied into reservoir chamber 71 through water supply pipe P1 and supply device 13. Further, the detergent is appropriately put into the reservoir 71 by the automatic detergent putting device. Accordingly, in washing space 7h, dish TW1 is washed with the washing water for a predetermined time. During the washing of dishes TW1, the water level sensor monitors the level of the washing water in washing space 7 h. The controller C1 controls the operation of the water supply solenoid valve 37 and the like as appropriate based on the water level of the washing water detected by the water level sensor.

After the washing of dishes TW1 is completed, the washing water is drained through drain pipe P2. Further, after washing of tableware TW1, tableware TW1 was washed. At this time, the supply device 13 supplies the treated water containing the rinsing agent 300 supplied from the storage box 15 into the water storage chamber 71. Accordingly, the treatment of the treated water was performed for the tableware TW1 together with the rinsing. After the treatment of the treated water is completed, the treated water is discharged through a drain pipe P2, and the water droplets attached to the dishes TW1 during the washing are dried by the drying fan 77. Thus, the washing operation of the tableware TW1 is ended. Here, since the time for drying the water droplets adhering to tableware TW1 was shortened by rinse 300, water marks were less likely to be generated on the dried tableware TW 1.

Thus, according to the dishwasher 1, the rinsing agent 300 stored in the storage box 15 is automatically supplied to the reservoir chamber 71 together with water by the supply device 13. Thus, according to the dish washing machine 1, there is no need to: in order to prevent water marks from being generated on the dried dishes TW1, the user himself/herself supplies the rinse agent 300 or the treated water containing the rinse agent 300 to the reservoir chamber 71 and the washing space 7 h. As a result, according to the dishwasher 1, it is possible to easily prevent the water mark from being generated on the dish TW 1. After the washing operation of tableware TW1 is completed, the user can take out tableware TW1 from washing space 7h by moving movable body 5 to the open position, and can store tableware TW1 while continuing to be stored in washing space 7 h.

In the dish washing machine 1, the 1 st and 2

nd electrodes

21 and 23 are provided in the cartridge main body 15a of the storage cartridge 15. While the storage box 15 is mounted in the cleaning tank 7, the 1 st and 2

nd electrodes

21 and 23 monitor the remaining amount of the rinse agent 300 stored in the box main body 15 a. Specifically, as shown in fig. 7 (a), when the amount of the rinse agent 300 stored in the cartridge main body 15a is large and both the 1 st electrode 21 and the 2 nd electrode 23 are immersed in the rinse agent 300, the resistance value between the 1 st electrode 21 and the 2 nd electrode 23 becomes minimum. On the other hand, when the remaining amount of the rinse agent 300 stored in the cartridge main body 15a is reduced and only the 1 st electrode 21 starts to be immersed in the rinse agent 300, the resistance value between the 1 st electrode 21 and the 2 nd electrode 23 starts to increase. As shown in fig. 7 (B), the remaining amount of the rinse agent 300 stored in the cartridge main body 15a is almost zero including a state in which only the front end of the 1 st electrode 21 is immersed in the rinse agent 300, and thus the resistance value between the 1 st electrode 21 and the 2 nd electrode 23 is maximized. Such a change in the resistance values of the 1 st and 2

nd electrodes

21 and 23 due to the remaining amount of the rinsing agent 300 is transmitted to the controller C1 through the connection unit 174. Accordingly, the controller C1 displays the remaining amount of the rinsing agent 300 monitored by the 1 st and 2

nd electrodes

21 and 23 on the liquid crystal panel 41. Accordingly, the user can recognize the remaining amount of the rinsing agent 300 stored in the storage box 15, and perform the rinsing agent 300 replenishment operation as needed. The controller C1 may cause the liquid crystal panel 41 to constantly display a change in the remaining amount of the rinsing agent 300 based on a change in the resistance values of the 1 st and 2

nd electrodes

21 and 23, or may cause the liquid crystal panel 41 to display the remaining amount of the rinsing agent 300 when the resistance values of the 1 st and 2

nd electrodes

21 and 23 exceed a predetermined threshold value.

Here, in the dish washing machine 1, the storage box 15 is detachable from the washing tub 7. Thus, the user can replenish the rinse agent 300 into the cartridge main body 15a through the replenishment port 153 of the cartridge cover 15b in a state where the storage cartridge 15 is detached from the cleaning tank 7. Accordingly, the user can perform the replenishment work of replenishing the rinsing agent 300 to the storage tank 15 at a place remote from the cleaning tank 7 or the tank 3. This makes it possible to facilitate the replenishment work of the rinse agent 300, as compared with the case where the replenishment work of the rinse agent 300 is performed in a state where the storage box 15 is attached to the cleaning tank 7. Thus, according to the dish washing machine 1, it is possible to prevent: when rinsing agent 300 is replenished, a part of rinsing agent 300 is scattered on cleaning tank 7, upper panel 11, case 3, and the like.

In the dish washing machine 1, the attaching/detaching direction when attaching/detaching the storage box 15 to/from the washing tub 7 is the vertical direction, and is different from: the front-rear direction when the moving body 5 is moved between the storage position and the open position. Thus, according to the dish washing machine 1, it is possible to prevent: when the storage box 15 is attached to and detached from the washing tub 7, the movable body 5 is inadvertently moved back and forth with respect to the case 3. In addition, according to the dish washing machine 1, it is possible to prevent: by moving the moving body 5 forward and backward with respect to the case body 3, the storage box 15 in a state of having been mounted on the wash bowl 7 is detached from the wash bowl 7 unintentionally.

Therefore, in the dish washing machine 1 of embodiment 1, in the configuration having the storage box 15 that stores the rinse agent 300, the user can appropriately replenish the storage box 15 with the rinse agent 300.

In particular, in the dish washing machine 1, the storage box 15 mounted in the washing tub 7 is located at a position between the front panel 9 and the front of the washing tub 7. Accordingly, according to dishwasher 1, for example, as compared with a configuration in which storage box 15 is detachably attached to the rear portion of washing tub 7, it is possible for the user to easily attach and detach storage box 15 to and from washing tub 7. Further, according to the dishwasher 1, when attaching and detaching the storage box 15 to and from the washing tub 7, it is not always necessary to move the movable body 5 largely forward of the case 3. In this regard, according to the dish washing machine 1, the storage box 15 can be easily attached to and detached from the washing tub 7, and the rinsing agent 300 can be appropriately replenished to the storage box 15.

In addition, according to dishwasher 1, when storage box 15 is detached from washing tub 7, outflow prevention mechanism 19 prevents rinse agent 300 from flowing out from connection port 150. Accordingly, when the user performs the work of replenishing the rinsing agent 300 into the storage box 15 or mounts the storage box 15, to which the rinsing agent 300 has been replenished, on the washing tub 7, the user does not have to be aware of the problem of the rinsing agent 300 flowing out from the connection port 150, and therefore, the work of replenishing the rinsing agent 300 or the work of mounting the storage box 15 can be performed appropriately according to the dishwasher 1.

In the dishwasher 1, the 1 st and 2

nd electrodes

21 and 23 monitor the remaining amount of the rinsing agent 300 stored in the cartridge main body 15a based on a change in the resistance value therebetween. Accordingly, according to the dishwasher 1, the 1 st and 2

nd electrodes

21 and 23 can detect the remaining amount of the rinsing agent 300 with high accuracy. Further, since the remaining amount of the rinse agent 300 monitored by the 1 st and 2

nd electrodes

21 and 23 is displayed on the liquid crystal panel 41 and is notified to the user, the user does not need to visually check the inside of the storage case 15 through the refill port 153 to confirm the remaining amount of the rinse agent 300. Therefore, the dishwasher 1 can improve convenience.

In dish washing machine 1, case 17 is fixed to the front portion of washing tub 7, and storage box 15 is attached to and detached from washing tub 7 by being stored in and taken out from case 17. Accordingly, as compared with a case where the magazine 15 is directly attached to and detached from the washing tub 7, the magazine 15 can be easily attached to and detached from the washing tub 7. In addition, according to the dishwasher 1, by housing the storage box 15 in the case 17, even when a part of the rinse agent 300 adheres to the surface of the box main body 15a, the rinse agent 300 can be prevented from scattering in the housing space 90 or the inside of the case 3.

In addition, in the dish washing machine 1, the cartridge filter 16 is provided in the cartridge main body 15a of the storage cartridge 15. Thus, according to the dishwasher 1, even when foreign matter enters the cartridge main body 15a during replenishment of the rinse agent 300, the foreign matter is less likely to flow through the supply device 13 together with the rinse agent 300.

Further, according to the dish washing machine 1, in the storage box 15, the box cover 15b is detachable from the box main body 15 a. Thus, according to the dishwasher 1, the inside of the cartridge main body 15a can be easily cleaned as needed, and the cartridge filter 16 can be easily cleaned, replaced, and the like. Further, since the lid body 29 that can open and close the supply port 153 is provided in the lid 15b, foreign matter and the like are less likely to enter the inside of the case main body 15a from the supply port 153. Further, according to the dishwasher 1, by vibration or the like during washing of the tableware TW1, it is possible to appropriately prevent: the rinse agent 300 stored in the cartridge main body 15a leaks to the outside through the supply port 153.

Example 2

As shown in fig. 11 and 12, the dishwasher 1 according to embodiment 2 includes a remaining amount monitoring device 500 in place of the remaining amount monitoring device 200. The remaining amount monitoring device 500 includes: a float 50, a float monitoring section 51, and a control section C1. In the dishwasher 1, the 1 st opening/closing chamber 175a is formed in the bottom wall 17a of the casing 17, and the 2 nd opening/closing chamber 175b is formed in the peripheral wall 17 b.

The float 50 is provided in the cartridge body 15 a. As shown in fig. 13 and 14, the float 50 is made of resin and includes: a float body 50a, a float cover 50b, and a shaft body 50 c. The float main body 50a is formed in a bottomed cylindrical shape. Inside the float main body 50a are formed: an air chamber 501 for floating the float main body 50a in the rinsing agent 300. Further, a magnet 502 is provided inside the float main body 50 a. The magnet 502 is an example of the "magnetic body" in the present invention. The magnet 502 is a general-purpose article and is fixed inside the float main body 50 a.

The float cover 50b is attached to the float main body 50 a. Accordingly, the float cover 50b ensures airtightness of the interior of the float main body 50a including the air chamber 501, thereby preventing the rinse agent 300 from entering the interior of the float main body 50 a. The shaft body 50c is formed in a substantially rectangular shape. In fig. 13, the cartridge filter 16 is not shown for ease of explanation.

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

The float monitoring section 51 is constituted by a 1 st reed switch 51a and a 2 nd reed switch 51 b. The 1 st and 2

nd reed switches

51a and 51b are general-purpose devices and can monitor the magnetism of the magnet 502. The 1 st reed switch 51a is held in the 1 st switch chamber 175 a. Reed switch No. 2 51b is held within switch No. 2 chamber 175 b. Thus, the 1 st and 2

nd reed switches

51a and 51b are provided on the bottom wall 17a and the peripheral wall 17b, respectively. Further, the 1 st and 2

nd reed switches

51a and 51b are electrically connected to the control unit C1.

As shown in fig. 13 and 14, in the dish washing machine 1, a 1 st coupling part 158 and a 2 nd coupling part 159 are formed with respect to the box cover 15 b. The 1 st coupling part 158 and the 2 nd coupling part 159 are coupled to the cover 15b at upper ends thereof and extend downward. The lower ends of the 1 st coupling portion 158 and the 2 nd coupling portion 159 are coupled to the other end of the shaft body 50c in the axial direction by the 2 nd mounting pin 60. Accordingly, as shown in fig. 11 and 12, the float 50 can swing around the 2 nd swing axis X2 with the axis of the 2 nd mounting pin 60 as the 2 nd swing axis X2 in the cartridge main body 15 a. The other components of the dishwasher 1 are the same as those of the dishwasher of embodiment 1, and the same reference numerals are given to the same components, and detailed description of the components is omitted.

In the dishwasher 1, the float 50 floats on the rinsing agent 300 stored in the cartridge main body 15a while the float main body 50a is connected to the shaft 50 c. Thereby, the float 50 swings around the 2 nd swing axis X2 in the cartridge main body 15 a. Here, the position of the float body 50a in the cartridge body 15a changes due to a change in the remaining amount of the rinse agent 300 stored in the cartridge body 15 a. That is, as shown in fig. 11, when the amount of the rinse agent 300 remaining is small, the float main body 50a moves downward of the cartridge main body 15a and approaches the bottom 151. On the other hand, as shown in fig. 12, when the amount of the rinse agent 300 remaining is large, the float main body 50a moves upward of the cartridge main body 15a and approaches the peripheral wall portion 152.

Further, since the float main body 50a approaches the bottom 151 with a small amount of the rinse agent 300 remaining, the magnetism of the magnet 502 detected by the 1 st reed switch 51a becomes large, and the magnetism of the magnet 502 detected by the 2 nd reed switch 51b becomes small. Conversely, when the amount of the remaining rinsing agent 300 is large, the float main body 50a approaches the peripheral wall portion 152, and the magnetism of the magnet 502 detected by the 1 st reed switch 51a decreases, while the magnetism of the magnet 502 detected by the 2 nd reed switch 51b increases. In this way, the float monitoring unit 51 detects the position of the float main body 50a in the cartridge main body 15a based on the magnitude of the magnetism of the magnet 502 monitored by the 1 st and 2

nd reed switches

51a and 51 b. Further, the float monitoring unit 51 and the remaining amount monitoring device 500 can monitor the remaining amount of the rinsing agent 300 in the cartridge body 15a based on the monitored position of the float body 50 a. In this way, even in the dishwasher 1, the remaining amount of the rinsing agent 300 can be accurately monitored by the remaining amount monitoring device 500. In addition, in the dishwasher 1, the remaining amount of the rinsing agent 300 monitored by the remaining amount monitoring device 500 is also displayed on the liquid crystal panel 41.

In the dishwasher 1, the shaft body 50c is connected to the lower ends of the 1 st and 2

nd connecting portions

158 and 159, and the float 50 is connected to the lid 15 b. Accordingly, the installation of the float 50 becomes easy. As shown in fig. 14, according to the dishwasher 1, the float 50 can be detached from the box main body 15a by detaching the box cover 15b from the box main body 15 a. Thus, according to the dishwasher 1, the float 50 can be easily replaced or cleaned.
