Summary of the Invention

Problems to be Solved by the Invention

[0007] However, in the conventional dishwasher, when a user stores an object to be washed in the washing tank, the detergent supply port is likely to be hidden by the stored object to be washed. For this reason, in this dishwasher, it is difficult to supply the detergent from the detergent supply port to the storage tank after storing the object to be washed in the washing tank. As a result, it is difficult to improve the convenience for the user when using the detergent.

[0008] The present invention has been made in view of the above-described conventional circumstances, and an object to be solved is to provide a dishwasher capable of improving the convenience for the user when using a detergent.

Means for Solving the Problems

[0009] The dishwasher of the present invention includes a housing having an open front, a moving body movable between a storage position accommodated in the housing and a pull-out position moved forward from the storage position, a washing tank provided on the moving body and having an upwardly open opening for accommodating an object to be washed, a lid provided in the housing and configured to close the opening of the washing tank when the moving body is in the storage position, and to open the opening when the moving body moves between the storage position and the pull-out position, a storage tank provided on the moving body for storing a detergent supplied into the washing tank, a detergent supply port provided on the moving body for supplying the detergent to the storage tank, and is a dishwasher comprising: An annular sealing region for sealing a gap with the lid that closes the opening when the moving body is in the storage position is formed at a peripheral edge surrounding the opening in the washing tank. The treatment agent supply port is located in front of the sealing region and at a position that is exposed to the outside of the housing when the moving body moves to the pull-out position, and is disposed on a surface facing upward between the front surface of the moving body and the sealing region. The moving body includes a cover body that closes the treatment agent supply port. The storage tank is open at the top by the treatment agent supply port that is integral with the storage tank. The cover body is detachably provided on the storage tank. The front end of the lid body is characterized in that it is located behind the cover body that closes the treatment agent supply port in a state where the lid body closes the opening of the washing tub.

[0010] In the dishwasher of the present invention, the treatment agent supply port is disposed at a position not covered by the object to be washed accommodated in the washing tub. Thereby, the user can easily supply the treatment agent from the treatment agent supply port to the storage tank regardless of whether the object to be washed is accommodated in the washing tub before or after.

[0011] Therefore, in the dishwasher of the present invention, it is possible to improve the convenience of the user when using the treatment agent.

[0012] Further, in this dishwasher, the washing water sprayed or scattered in the washing tub during the washing of the object to be washed accommodated in the washing tub is blocked by the lid body that closes the opening and is difficult to reach outside the sealing region. For this reason, in this dishwasher, it is possible to highly reliably suppress the washing water from hitting and soiling the treatment agent supply port and its periphery. Further, in this dishwasher, even when the treatment agent supply port is left open without being blocked by, for example, a cover body or the like, it is possible to highly reliably suppress the washing water from entering from the treatment agent supply port.

[0013] The treatment agent supply port is arranged in front of the sealing area. With this configuration, when the user moves the moving body to the pulling-out position to expose the treatment agent supply port to the outside of the housing, the required moving distance can be shortened, so that the treatment agent can be more easily supplied from the treatment agent supply port to the storage tank. Further, with this configuration, it is possible to highly reliably suppress water droplets or the like adhering to the back surface of the lid body from dripping onto the treatment agent supply port when the moving body is pulled out.

[0014] The treatment agent supply port is arranged on the upward-facing surface between the front surface of the moving body and the sealing area. With this configuration, compared with the case where the treatment agent supply port is arranged on the side-facing surface between the front surface and the sealing area, the treatment agent can be more easily supplied from the treatment agent supply port to the storage tank.

[0015] The moving body is provided with a cover body that closes the treatment agent supply port. With this configuration, it is possible to highly reliably suppress foreign matter from entering the storage tank from the treatment agent supply port by means of the cover body.

Advantages of the Invention

[0016] According to the dishwasher of the present invention, it is possible to improve the convenience of the user when using the treatment agent.

The housing opening 9H opens a wide range from the upper end to the lower end of the front part of the housing 9, and communicates the inside of the housing 9 with the outside.

[0023] The moving body 6 is housed in the housing 9. The position of the moving body 6 shown in FIG. 1 is defined as the housing position. A slide rail mechanism (not shown) is arranged between the side surface of the moving body 6 and the inner wall surface of the housing 9. The moving body 6 can move between the housing position shown in FIG. 1 and the drawer position moved forward from the housing position as shown in FIG. 2 by the slide rail mechanism. The moving body 6 is provided with a washing tank 7 and a door body 70.

[0024] As shown in FIGS. 1 to 5, the washing tub 7 is a substantially box-shaped body, and an internal space for washing the tableware TW1 is defined by a front wall 7A, left and right side walls, and a rear wall. Further, the washing tub 7 has an opening 7H that opens the upper part of its internal space, and an annular peripheral edge 7R that surrounds the opening 7H.

[0025] As shown in FIGS. 4 and 5, an annular sealing region E1 is formed on the peripheral edge 7R of the washing tub 7. The sealing region E1 is for sealing a gap with a lid body 8 that closes the opening 7H when the moving body 6 is in the storage position shown in FIG. 1.

[0026] As shown in FIGS. 1 to 5, the door body 70 is provided in front of the washing tub 7 by being integrally assembled from the front to the front wall 7A of the washing tub 7. The front surface 70F of the door body 70 is a plane extending in the vertical and horizontal directions, and constitutes a design surface that comes into contact with the eyes of a user who uses the built-in kitchen. The front surface 70F of the door body 70 is an example of the "front surface of the moving body" of the present invention. At the upper end of the door body 70, a door body protruding portion 78 and a door body upper surface cover 77 are provided.

[0027] The door body protruding portion 78 projects forward and upward from the upper portion of the front surface 70F of the door body 70, and extends in the left-right direction and protrudes in the left-right direction from the left end and the right end of the front surface 70F of the door body 70.

[0028] As shown in FIGS. 1 and 3, a handle 7G is provided at the center in the left-right direction on the front surface of the door body protruding portion 78. The handle 7G is gripped by the user when moving the moving body 6 between the storage position shown in FIG. 1 and the pull-out position shown in FIG. 2.

[0029] As shown in FIGS. 4 and 5, the upper cover 77 of the door body covers the upper surface of the door body protrusion 78 from above by a first upper surface 71 that extends substantially horizontally. Further, the upper cover 77 of the door body covers the rear surface of the door body protrusion 78 from behind by an intermediate surface 73 that is connected to the rear end of the first upper surface 71 and extends downward. Furthermore, the upper cover 77 of the door body covers the door body 70 from above by a second upper surface 72 that is connected to the lower end of the intermediate surface 73 and extends substantially horizontally rearward and is connected to the front end of the peripheral edge 7R of the cleaning tank 7.

[0030] The first upper surface 71 and the second upper surface 72 are in two upper and lower stages, and the first upper surface 71 is located in front of and above the second upper surface 72. The second upper surface 72 is an example of the "surface facing upward between the front surface of the moving body and the sealing region" of the present invention.

[0031] In a state where the moving body 6 is in the storage position shown in FIG. 1, the door body 70 closes the housing opening 9H, and the cleaning tank 7 is housed in the housing 9. Then, when the moving body 6 moves to the pull-out position shown in FIG. 2, the door body 70 opens the housing opening 9H, and the opening 7H of the cleaning tank 7 is exposed from the housing 9.

[0032] As shown in FIGS. 1 and 2, the lid body 8 is disposed in the upper part of the housing 9. The lid body 8 is configured to move up and down in conjunction with the movement of the moving body 6 by an interlocking mechanism (not shown). A seal member 8S is attached to the lower surface of the lid body 8. The seal member 8S is made of an elastic body such as rubber or a foam of closed-cell foam, and is formed in an annular shape that matches the annular sealing region E1.

[0033] The lid body 8 descends when the moving body 6 is in the storage position shown in FIG. 1 to close the opening 7H of the cleaning tank 7. At this time, the seal member 8S of the lid body 8 is in close contact with the sealing region E1, thereby sealing the gap between the peripheral edge 7R of the cleaning tank 7 and the lid body 8. On the other hand, the lid body 8 ascends when the moving body 6 moves between the storage position shown in FIG. 1 and the pull-out position shown in FIG. 2, opens the opening 7H, and allows the movement of the moving body 6.

[0034] When the moving body 6 moves to the drawer position shown in FIG. 2 and the opening 7H of the washing tank 7 is exposed from the housing 9, the user can accommodate the tableware TW1 in the washing tank 7 or take out the tableware TW1 from the washing tank 7 through the opening 7H.

[0035] The tableware TW1 is, for example, eating utensils such as bowls, plates, glasses, and eating implements such as chopsticks, spoons, forks, etc. The tableware TW1 is an example of the "object to be washed" of the present invention.

[0036] Note that a detergent automatic feeder (not shown) is provided in the moving body 6. Inside the detergent automatic feeder, a detergent for decomposing and washing away the dirt adhering to the tableware TW1 is stored. The detergent automatic feeder automatically feeds the stored detergent into the washing tank 7 at a predetermined timing.

[0037] As shown in FIG. 1, a water supply pipe P1, a water supply solenoid valve 69, and a drain pipe P2 are provided in the housing 9.

[0038] The water supply pipe P1 extends forward between the bottom wall of the moving body 6 and the bottom wall of the washing tank 7 and is connected to a water supply port 7S provided on the front wall 7A of the washing tank 7. The water supply pipe P1 supplies water from a water supply source (not shown) provided outside the dishwasher 1 into the washing tank 7.

[0039] As will be described later, a treatment agent supply device 20 is provided in the middle of the water supply pipe P1, and a storage tank 10 is provided above the treatment agent supply device 20. A rinse R1 for improving the water drainage of the tableware TW1 and obtaining a gloss after washing is stored in the storage tank 10. The rinse R1 is an example of the "treatment agent" of the present invention. In this embodiment, the rinse R1 is a liquid. The treatment agent supply device 20 supplies the rinse R1 into the washing tank 7 by mixing the stored rinse R1 into the water supplied into the washing tank 7 at a predetermined timing.

[0040] The water supply solenoid valve 69 opens and closes the water supply pipe P1 to switch the supply and stop of water into the washing tank 7. The drain pipe P2 drains the washing water in the washing tank 7 to the outside of the dishwasher 1.

[0041] At the bottom inside the washing tub 7, a water storage part 7P for storing washing water is provided. Also, a dish basket 7C is arranged inside the washing tub 7. Dishes TW1 are placed on the dish basket 7C.

[0042] As shown in FIGS. 1 and 3, the washing tub 7 is provided with an exhaust passage 7E. The exhaust passage 7E opens at a portion located above and to the left on the front surface 70F of the door body 70 and communicates with the outside of the washing tub 7. The air inside the washing tub 7 passes through the exhaust passage 7E and is discharged outside the machine, that is, in front of the housing 9.

[0043] <Nozzle and Pump> As shown in FIG. 1, the dishwasher 1 further includes a nozzle 61 and a pump 62. The nozzle 61 is arranged inside the washing tub 7. The pump 62 is assembled at the lower part of the water storage part 7P of the washing tub 7.

[0044] The nozzle 61 can inject washing water into the washing tub 7 from a plurality of ejection holes. The ejection direction of the nozzle 61 is changed in various directions in order to surely wash a plurality of dishes TW1 stacked inside the washing tub 7 or to wash the inner wall surface of the washing tub 7 and the dish basket 7C.

[0045] When the pump 62 rotates forward, it supplies the washing water stored in the water storage part 7P of the washing tub 7 to the nozzle 61 and injects it into the washing tub 7. Since the injected washing water is stored in the water storage part 7P, it is repeatedly supplied to the nozzle 61 by the pump 62. Also, when the pump 62 rotates in reverse, it drains the washing water inside the washing tub 7 to the outside of the dishwasher 1 through the food residue filter 67 and the drain pipe P2.

[0046] <Heater and Drying Fan> The dishwasher 1 further includes a heater 63 and a drying fan 68. The heater 63 and the drying fan 68 are also assembled to the washing tub 7.

[0047] The heater 63 is disposed at the bottom of the water storage section 7P. The heater 63 heats the washing water stored in the water storage section 7P of the washing tub 7 or the air in the washing tub 7.

[0048] The drying fan 68 rotates in a state where the heater 63 is operating, thereby sending the heated air into the washing tub 7 to dry the tableware TW1. The air sent into the washing tub 7 by the drying fan 68 is exhausted to the outside of the dishwasher 1 via the exhaust passage 7E.

[0049] <Control Unit and User Interface> The dishwasher 1 further includes a control unit C1 and a user interface 79. As shown in FIG. 3, the control unit C1 is disposed below the right end of the door projection 78 on the door body 70. As shown in FIGS. 4 and 5, the user interface 79 is disposed at the right portion of the first upper surface 71 of the door upper surface cover 77.

[0050] The control unit C1 is an electronic circuit unit including a CPU (not shown), a memory constituted by storage elements such as a ROM and a RAM, an interface circuit that transmits and receives signals to and from a control target, and a power supply circuit that controls power supply to the control target. The memory stores programs and setting information for operating the dishwasher 1.

[0051] The control unit C1 controls and operates the pump 62, the heater 63, the drying fan 68, etc. Further, the control unit C1 controls and operates a detergent automatic feeding device and a processing agent supply device 20 (not shown) at a predetermined timing. Furthermore, the control unit C1 receives detection signals from sensors (not shown), for example, a temperature sensor for controlling the heater 63, a water level sensor for detecting the water level of the washing water in the washing tub 7, a position sensor for detecting whether the washing tub 7 is in the accommodation position, a lock sensor for detecting whether the washing tub 7 is locked in the accommodation position, etc.

[0052] The user interface 79 has an operation instruction unit 79A and a display unit 79B. The operation instruction unit 79A inputs operation instructions for the dishwasher 1 by a plurality of buttons and transmits the input results to the control unit C1. The display unit 79B has information related to the operation of the dishwasher 1 transmitted from the control unit C1 and displays the information by a liquid crystal panel or the like.

[0053] As shown in FIG. 1, in a state where the washing tub 7 is in the storage position, the entire user interface 79 is concealed by the top plate CT1 of the built-in kitchen cabinet. For this reason, the user cannot operate and visually recognize the user interface 79. When the moving body 6 moves to the drawer position shown in FIG. 2 and the entire user interface 79 moves forward from the top plate CT1 of the built-in kitchen cabinet, the user can operate and visually recognize the user interface 79.

[0054] <Detergent supply device, case, storage tank, detergent replenishment port, and cover body> As shown in FIGS. 1 and 3, in the space between the front surface 70F of the door body 70 and the front wall 7A of the washing tub 7 in the moving body 6, a detergent supply device 20, a case 19, a storage tank 10, a detergent replenishment port 10H, and a cover body 15 are provided.

[0055] The detergent supply device 20 is arranged in the middle of the water supply pipe P1, immediately before the water supply port 7S. An upper portion of the detergent supply device 20 is provided with a connecting pipe 28 projecting upward.

[0056] Although not shown, the detergent supply device 20 has a plurality of solenoid valves, a metering pump, and the like. Each solenoid valve switches the water flow path in the detergent supply device 20 or switches the supply and stop of the rinse R1 when the rinse R1 is not mixed into the water supplied into the washing tub 7 and when the rinse R1 is mixed. The metering pump operates when the rinse R1 is mixed into the water supplied into the washing tub 7 and mixes the rinse R1 while accurately measuring it.

[0057] Case 19 is disposed above the treatment agent supply device 20. Case 19 is a box-shaped body, and the upper portion of the connection pipe 28 is inserted through the bottom wall portion thereof. Case 19 is open at the top by a rectangular opening.

[0058] As shown in FIGS. 4 and 5, a tank mounting hole 72H is provided in the second upper surface 72 of the door body upper surface cover 77. The tank mounting hole 72H is opened in a rectangular shape so as to be aligned with the upper opening of the case 19.

[0059] As shown in FIGS. 2 and 3, the storage tank 10 is detachably provided in the case 19. The storage tank 10 is a box-shaped body, and a connected portion 18 is provided in the bottom wall portion thereof.

[0060] The connected portion 18 communicates with the connection pipe 28 in a state where the storage tank 10 is mounted on the case 19 as shown by the solid line in FIGS. 2 and 3. Thereby, the rinse R1 stored in the storage tank 10 can be supplied into the treatment agent supply device 20 via the connected portion 18 and the connection pipe 28. On the other hand, the connected portion 18 is closed by a check valve (not shown) in a state where the storage tank 10 is removed from the case 19 as shown by the two-dot chain line in FIGS. 2 and 3. Thereby, the rinse R1 remaining in the removed storage tank 10 does not leak from the connected portion 18.

[0061] As shown in FIGS. 3 to 5, the storage tank 10 is open at the top by a treatment agent replenishment port 10H which is a rectangular opening. That is, in the present embodiment, the treatment agent replenishment port 10H for replenishing the rinse R1 to the storage tank 10 is provided in the moving body 6 integrally with the storage tank 10.

[0062] As shown in FIGS. 4 and 5, the treatment agent replenishment port 10H is disposed on the second upper surface 72 of the door body upper surface cover 77 in a state where the storage tank 10 is mounted on the case 19. In this state, the treatment agent replenishment port 10H is surrounded by the inner peripheral edge of the tank mounting hole 72H. Further, the user interface 79 disposed on the first upper surface 71 of the door body upper surface cover 77 is located above and in front of the treatment agent replenishment port 10H.

[0063] The treatment agent supply port 10H is disposed outside the sealing region E1, more specifically, in front of the sealing region E1. Further, as shown in FIG. 2, the treatment agent supply port 10H is disposed at a position where it is exposed to the outside of the housing 9 when the moving body 6 moves to the pull-out position.

[0064] As shown in FIG. 3, the cover body 15 is detachably provided at the upper end of the storage tank 10. As shown in FIGS. 4 and 5, the cover body 15 is a rectangular lid that is larger than the treatment agent supply port 10H and smaller than the tank mounting hole 72H.

[0065] With the cover body 15 attached to the upper end of the storage tank 10, the treatment agent supply port 10H is closed. Also, in this state, the upper surface of the cover body 15 is substantially flush with the second upper surface 72 of the door body upper surface cover 77.

[0066] As shown in FIG. 5, the cover body 15 is provided with a supply hole 15H, an opening / closing lid 15A, and gripping recesses 15B and 15C.

[0067] The supply hole 15H opens in a rectangular shape smaller than the treatment agent supply port 10H at the left end of the cover body 15. The opening / closing lid 15A closes the supply hole 15H as shown by the solid line in FIG. 5. When the user swings the opening / closing lid 15A to the position shown by the two-dot chain line in FIG. 5 and pours the rinse R1 through the opened supply hole 15H, the storage tank 10 is replenished with the rinse R1.

[0068] The gripping recesses 15B and 15C are recessed downward at the center and the right end of the upper surface of the cover body 15. By the user gripping the gripping recesses 15B and 15C and lifting the cover body 15, the storage tank 10 can be removed from the case 19 integrally with the cover body 15. Then, as shown by the two-dot chain line in FIG. 3, by removing the cover body 15 from the storage tank 10, the storage tank 10 and the cover body 15 can be suitably washed respectively.

[0069] As shown in Fig. 1, the end portion formed outside (frontward) of the seal member 8S in the lid body 8 does not extend above the cover body 15 that closes the treatment agent supply port 10H, nor does it extend above the opening / closing lid 15A that closes the supply hole 15H shown in Figs. 4 and 5, in a state where the lid body 8 closes the opening 7H of the cleaning tank 7. That is, the end portion formed outside (frontward) of the seal member 8S in the lid body 8 is formed at a position where it does not contact the cover body 15 or the opening / closing lid 15A, even if the attachment of the cover body 15 or the opening / closing lid 15A is insufficient. With this configuration, when the lid body 8 closes the opening 7H of the cleaning tank 7, it is possible to suppress the problem that the seal member 8S comes into contact with the cover body 15 or the opening / closing lid 15A with insufficient attachment, resulting in poor adhesion in the sealing region E1 and inhibiting the sealing of the gap between the peripheral edge 7R of the cleaning tank 7 and the lid body 8.

[0070] <Washing operation> In the dishwasher 1 having the above configuration, the washing operation is executed in the following procedure. In this embodiment, the washing operation includes a washing step, a rinsing step, and a drying step.

[0071] The user holds the handle 7G of the door body protrusion 78 and moves the moving body 6 to the pull-out position shown in Fig. 2 in order to accommodate the tableware TW1 to be washed in the cleaning tank 7. Then, the user accommodates the tableware TW1 in the cleaning tank 7 with the opening 7H opened. Further, the user opens the opening / closing lid 15A of the cover body 15, pours the rinse R1 from the supply hole 15H, replenishes the storage tank 10 with the rinse R1, and then closes the opening / closing lid 15A.

[0072] At this time, the accommodation of the tableware TW1 in the cleaning tank 7 and the replenishment of the rinse R1 to the storage tank 10 can be done in either order. Thereafter, the user operates the user interface 79 to instruct the start of the washing operation and moves the moving body 6 to the pull-out position shown in Fig. 1.

[0073] Then, the control unit C1 executes the washing operation and starts the washing process on the condition that a position sensor (not shown) detects that the washing tub 7 is in the storage position and a lock sensor (not shown) detects that the washing tub 7 is locked in the storage position.

[0074] In the washing process, the control unit C1 opens the water supply solenoid valve 69 to supply water into the washing tub 7 through the water supply pipe P1. At this time, the control unit C1 automatically inputs an amount of detergent corresponding to the tableware TW1 stored in the washing tub 7 into the washing tub 7 by a detergent automatic input device (not shown). Also, in the washing process, the control unit C1 controls the treatment agent supply device 20 so as not to mix the rinse R1 into the water supplied into the washing tub 7.

[0075] Then, the control unit C1 operates the pump 62 to inject washing water from the nozzle 61 into the washing tub 7 to wash the tableware TW1.

[0076] When the washing process is finished, the control unit C1 reverses the pump 62 to drain the washing water in the washing tub 7 to the outside of the dishwashing machine 1, and then starts the rinsing process.

[0077] In the rinsing process, the control unit C1 opens the water supply solenoid valve 69 to supply water into the washing tub 7 through the water supply pipe P1. At this time, the control unit C1 controls the treatment agent supply device 20 so as to mix the rinse R1 into the water supplied into the washing tub 7. Thereby, the treatment agent supply device 20 accurately measures an amount of the rinse R1 corresponding to the tableware TW1 stored in the washing tub 7 and mixes it into the water supplied into the washing tub 7.

[0078] Then, the control unit C1 operates the pump 62 to inject the washing water mixed with the rinse R1 from the nozzle 61 into the washing tub 7 to rinse the tableware TW1.

[0079] When the rinsing process is finished, the control unit C1 reverses the pump 62 to drain the washing water used for rinsing in the washing tub 7 to the outside of the dishwashing machine 1, and then starts the drying process.

[0080] During the drying process, the control unit C1 appropriately operates the heater 63 and the drying fan 68, and sends the heated air into the washing tank 7 to dry the tableware TW1 in the washing tank 7. When the drying process is completed, the control unit C1 ends the washing operation.

[0081] In the drying process, the draining of the tableware TW1 is improved by the rinse R1 contained in the water droplets adhering to the tableware TW1 at the end of the rinsing process, and it is possible to suppress the tableware TW1 from remaining with water droplets adhering thereto. As a result, the required time for the drying process can be shortened, and it is possible to suppress spots from occurring on the dried tableware TW1 due to the water droplets remaining adhered to the tableware TW1. In addition, the gloss component contained in the rinse R1 makes it easier to obtain the washed gloss of the tableware TW1.

[0082] <Function and effect> In the dishwasher 1 of the embodiment, as shown in FIGS. 2, 4, and 5, the treatment agent supply port 10H is located at a position not covered by the tableware TW1 accommodated in the washing tank 7, that is, outside the sealing region E1 and at a position exposed to the outside of the housing 9 when the moving body 6 moves to the pull-out position. Thereby, regardless of whether the user places the tableware TW1 in the washing tank 7 before or after, the user can easily supply the rinse R1 from the treatment agent supply port 10H to the storage tank 10 through the supply hole 15H of the cover body 15.

[0083] Therefore, in the dishwasher of the embodiment, it is possible to improve the convenience for the user when using the rinse R1.

[0084] Also, in this dishwasher 1, as shown in FIG. 1, the washing water that is jetted or scattered in the washing tub 7 during the washing of the tableware TW1 accommodated in the washing tub 7 is blocked by the lid body 8 and the seal member 8S that close the opening 7H and it is difficult to reach the outside of the sealing region E1. For this reason, in this dishwasher 1, it is possible to highly reliably suppress the washing water from adhering to the detergent supply port 10H and its periphery and getting dirty. Further, in this dishwasher 1, even when the cover body 15 is removed from the upper end of the storage tank 10 and the detergent supply port 10H is left open, it is possible to highly reliably suppress the washing water from entering from the detergent supply port 10H. As a result, it is possible to suppress the detergent components and dirt components contained in the washing water from mixing into the rinse R1 and degrading the quality of the rinse R1.

[0085] Furthermore, in this dishwasher 1, as shown in FIGS. 4 and 5, the detergent supply port 10H is disposed in front of the sealing region E1. With this configuration, the moving distance required when the user moves the moving body 6 to the pulled-out position shown in FIG. 2 and exposes the detergent supply port 10H to the outside of the housing 9 can be shortened, so that the rinse R1 can be more easily supplied from the detergent supply port 10H to the storage tank 10. Also, with this configuration, when the moving body 6 is pulled out to the pulled-out position, it is possible to highly reliably suppress water droplets or the like adhering to the back surface of the lid body 8 from dripping onto the detergent supply port 10H.

[0086] Also, in this dishwasher 1, as shown in FIG. 5, the detergent supply port 10H is disposed on the second upper surface 72 which is a surface facing upward between the front surface 70F of the door body 70 and the sealing region E1. With this configuration, compared to the case where the detergent supply port 10H is disposed on a surface facing leftward or rightward between the front surface 70F of the door body 70 and the sealing region E1, the rinse R1 can be more easily supplied from the detergent supply port 10H to the storage tank 10.

[0087] Furthermore, in this dishwasher 1, a user interface 79 having an operation instruction unit 79A and a display unit 79B is disposed on a first upper surface 71 of a door body upper surface cover 77 positioned above a detergent replenishment port 10H. With this configuration, when replenishing the rinse R1, even if the user fails to put the rinse R1 into the detergent replenishment port 10H, it is difficult for the rinse R1 to get into the user interface 79. As a result, in this dishwasher 1, it is possible to highly reliably suppress the user interface 79 from being soiled by the rinse R1.

[0088] Also, in this dishwasher 1, it is possible to highly reliably suppress foreign matter from entering the storage tank 10 from the detergent replenishment port 10H by a cover body 15 that closes the detergent replenishment port 10H.

[0089] As described above, although the present invention has been described with reference to the embodiments, it goes without saying that the present invention is not limited to the above embodiments and can be appropriately modified and applied without departing from the gist thereof.

[0090] In the embodiment, the detergent is the liquid rinse R1, but the present invention is not limited to this configuration. For example, the detergent may be a dishwashing detergent, and in addition to a liquid, it may also be a powder, a tablet, or the like.

[0091] Also, in the embodiment, a cover body 15 that closes the detergent replenishment port 10H provided in the storage tank 10 is provided, but a replenishment hole 15H provided in the cover body 15 may be used as the detergent replenishment port of the present invention, and an opening / closing lid 15A that closes the replenishment hole 15H may be used as the cover body of the present invention.

[0092] In the embodiment, the storage tank 10 is detachably provided in the case 19, but the present invention is not limited to this configuration. For example, a configuration in which the case 19 is removed from the embodiment and the connected portion 18 of the storage tank 10 is fixed to the connection pipe 28 of the detergent supply device 20 to make the storage tank 10 non-detachable is also included in the present invention.
