Description

Tableware cleaning machine

Technical Field

The present invention relates to a dishwasher.

Background

An example of a conventional dish washing machine is disclosed in japanese patent laid-open publication No. 2005-168523. The dish washing machine includes a housing, a movable body, a washing tub, and a lid body.

The front of the housing is open. The movable body is movable between a storage position where the movable body is stored in the housing and a pull-out position where the movable body is moved forward from the storage position. The cleaning tank is arranged on the moving body. The washing tub has an opening opened upward and can accommodate the objects to be washed, such as dishes. The cover body is arranged in the shell body. The cover body closes the opening of the cleaning tank when the movable body is at the storage position, and opens the opening when the movable body moves between the storage position and the pull-out position.

In addition, the dish washing machine includes: a storage box for storing the treating agent supplied to the cleaning tank, and a treating agent supply port for supplying the treating agent to the storage box. The treating agent is, for example: detergents for decomposing and washing dirt adhering to an object to be cleaned, rinsing agents (rinses) for improving water film residue of the object to be cleaned, and for obtaining gloss after washing, and the like. The storage box is provided on the movable body so as to be adjacent to an inner wall surface in front of the cleaning tank from the outside of the cleaning tank. The treating agent supply opening is arranged in the cleaning tank.

In the conventional dish washing machine having the above-described configuration, the opening of the washing tub is exposed to the outside of the casing by the user moving the movable body to the pulled-out position. Further, the user can start washing the object to be washed stored in the washing tank by moving the moving body to the storage position after replenishing the treatment agent from the treatment agent replenishment port to the storage box and storing the object to be washed in the washing tank.

However, in the above-described conventional dish washing machine, if the user accommodates the object to be washed in the washing tub, the treatment agent supply opening is easily hidden by the accommodated object to be washed. Therefore, in the dish washing machine, it is difficult to supply the treatment agent from the treatment agent supply port to the storage box after the objects to be washed are stored in the washing tub, and as a result, it is difficult to improve the usability for the user when using the treatment agent.

Disclosure of Invention

Accordingly, one non-limiting object of the present invention is to provide: a dishwasher capable of improving the convenience of use for the user when using a treating agent. This object is achieved by the teaching of claim 1. Further developments of the invention are described in the dependent claims.

The invention provides a dish washing machine, comprising: a housing opened at a front thereof; a movable body movable between a housed position housed in the housing and a pulled-out position moved forward from the housed position; a cleaning tank which is provided in the movable body, has an opening opened at an upper side, and can accommodate an object to be cleaned; a lid body provided in the housing and configured to close the opening of the cleaning tank when the movable body is at the storage position, and to open the opening when the movable body moves between the storage position and the pull-out position; a storage box provided in the movable body and storing the treating agent supplied into the cleaning tank; and a treatment agent replenishment port provided in the movable body for replenishing the treatment agent to the storage box, wherein an annular seal region for sealing a gap between the movable body and the lid body that closes the opening when the movable body is at the storage position is formed in a peripheral edge of the cleaning tank surrounding the opening, and the treatment agent replenishment port is disposed at a position outside the seal region and exposed to the outside of the housing when the movable body moves to the pulled-out position.

In the dish washing machine of the present invention, the treatment agent replenishment port is disposed at a position not covered by the objects to be washed stored in the washing tub. Thus, the user can easily supply the treating agent from the treating agent supply port to the storage box before or after the object to be washed is stored in the washing tank.

Therefore, in the dish washing machine of the present invention, the convenience of use for the user can be improved when the treatment agent is used.

In this dishwasher, the washing water sprayed or scattered in the washing tub during the washing of the objects to be washed accommodated in the washing tub is blocked by the lid body closing the opening and is hard to reach the outside of the sealed region. Therefore, in the dish washing machine, the washing water can be reliably prevented from falling to the treatment agent supply port or the periphery thereof and becoming dirty. In addition, in the dish washing machine, even in a state where the treatment agent supply port is not closed and opened by the cover or the like, for example, the washing water can be reliably suppressed from entering from the treatment agent supply port.

In another aspect of the present invention, the treatment agent replenishment port is preferably disposed in front of the sealing region. In this case, since the moving distance required when the user moves the movable body to the pulled-out position and exposes the treatment agent replenishment port to the outside of the housing can be shortened, the treatment agent can be more easily replenished from the treatment agent replenishment port to the storage box. In this case, it is possible to reliably prevent water droplets or the like adhering to the rear surface of the lid body from dropping to the treatment agent supply port when the movable body is pulled out.

In another aspect of the present invention, the treatment agent replenishment port is preferably disposed in: a face facing upward between the front face of the moving body and the seal region. In this case, the treatment agent can be supplied from the treatment agent supply port to the storage box more easily than in the case where the treatment agent supply port is disposed on a surface facing the side between the front surface and the sealing region.

In another aspect of the present invention, it is preferable that the dish washing machine of the present invention includes a user interface provided in the mobile body, the user interface including at least one of an operation instruction unit for inputting an operation instruction of the dish washing machine and a display unit for displaying information related to operation of the dish washing machine. Further, the user interface is preferably disposed above the treatment agent supply port. In this case, even if the user does not put the treatment agent into the treatment agent supply port at the time of supplying the treatment agent, the treatment agent is difficult to bypass the user interface. As a result, the dish washing machine can reliably prevent the user interface from being soiled with the treatment agent.

In another aspect of the present invention, it is preferable that the movable body includes a cover that closes the treatment agent replenishment port. In this case, the cover body can reliably suppress the entry of foreign matter from the treatment agent replenishment port into the storage box.

Other aspects and advantages of the present invention will become apparent from the following description and the accompanying drawings, which illustrate examples of the invention and are set forth in the specification and the drawings, which illustrate examples of the invention.

The door upper surface cover 77 covers the rear surface of the door protruding portion 78 from behind by an intermediate surface 73 that is connected to the rear end of the 1 st upper surface 71 and extends downward. Door body upper surface cover 77 covers door body 70 from above with 2 nd upper surface 72, and this 2 nd upper surface 72 is connected to the lower end of intermediate surface 73, extends substantially horizontally rearward, and is connected to the front end of peripheral edge 7R of washing tub 7.

The 1 st upper surface 71 and the 2 nd upper surface 72 are upper and lower 2 layers, and the 1 st upper surface 71 is located forward and upward of the 2 nd upper surface 72. The 2 nd upper surface 72 is an example of the "surface facing upward between the front surface of the moving body and the seal region" in the present invention.

In the state where moving body 6 is at the storage position shown in fig. 1, door 70 closes housing opening 9H, and cleaning tub 7 is stored in housing 9. Then, by moving body 6 to the pull-out position shown in fig. 2, door 70 opens case opening 9H, and opening 7H of cleaning tub 7 is exposed from case 9.

As shown in fig. 1 and 2, the lid 8 is disposed at an upper portion in the case 9. The cover 8 moves up and down in conjunction with the movement of the moving body 6 by an interlocking mechanism not shown. A sealing member 8S is attached to the lower surface of the lid 8. The sealing member 8S is made of an elastic body such as rubber, an open-cell foam, or the like, and is formed in an annular shape matching the annular sealing region E1.

When moving body 6 is at the storage position shown in fig. 1, lid 8 is lowered to close opening 7H of cleaning tub 7. At this time, the sealing member 8S of lid 8 is in close contact with sealing area E1, thereby sealing the gap between peripheral edge 7R of cleaning tank 7 and lid 8. On the other hand, the lid 8 is raised when the moving body 6 moves between the storage position shown in fig. 1 and the pull-out position shown in fig. 2, so that the opening 7H is opened and the moving body 6 is allowed to move.

In a state where moving body 6 moves to the pulled-out position shown in fig. 2 and opening 7H of washing tub 7 is exposed from casing 9, the user can accommodate tableware TW1 in washing tub 7 or take tableware TW1 out of washing tub 7 through opening 7H.

The tableware TW1 is, for example, a tableware such as a tea bowl, a plate, and a glass, or a tableware such as a chopstick, a spoon, and a fork. The dish TW1 is an example of the "object to be washed" of the present invention.

The moving body 6 is provided with an automatic detergent supply device, not shown. Detergent for decomposing and washing the dirt adhered to the dishes TW1 is stored in the automatic detergent dispenser. The automatic detergent supply device automatically supplies the stored detergent into the washing tub 7 at a predetermined timing.

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.

The water supply pipe P1 extends forward between the bottom wall of the moving body 6 and the bottom wall of the washing tub 7, and is connected to a water supply port 7S provided in the front wall 7A of the washing tub 7. The water supply pipe P1 supplies water from a water supply source, not shown, provided outside the dishwasher 1 into the washing tub 7.

The treatment agent supply device 20 is disposed in the middle of the water supply pipe P1 and in front of the water supply port 7S. A connection pipe 28 is provided at an upper portion of the treating agent supply device 20 so as to protrude upward.

Although not shown, the treating agent supply device 20 includes a plurality of solenoid valves, a metering pump, and the like. When rinse agent R1 is not mixed into the water supplied into cleaning tank 7, and when rinse agent R1 is mixed into the water supplied into cleaning tank 7, each solenoid valve switches the flow path of the water in treatment agent supply device 20, or switches the supply and stop of rinse agent R1. When the rinse agent R1 is mixed into the water supplied into the cleaning tank 7, the metering pump operates to accurately meter and mix the rinse agent R1.

The tank 19 is disposed above the treatment agent supply device 20. The case 19 is a box-shaped body, and an upper portion of the connection pipe 28 is inserted through a bottom wall portion of the case 19. The case 19 is opened upward through a rectangular opening.

As shown in fig. 4 and 5, the 2 nd upper surface 72 of the door upper surface cover 77 is provided with a box mounting hole 72H. The case mounting hole 72H is opened in a rectangular shape so as to match an opening above the case 19.

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

The connected portion 18 communicates with the connection pipe 28 in a state where the storage box 10 is attached to the case 19 as shown by solid lines in fig. 2 and 3. Thus, the rinse agent R1 stored in the storage box 10 can be supplied into the treatment agent supply device 20 through the connection portion 18 and the connection pipe 28. On the other hand, the connected portion 18 is closed by a non-illustrated check valve in a state where the storage box 10 is removed from the box body 19 as shown by the two-dot chain line in fig. 2 and 3. This prevents the rinse agent R1 remaining in the removed storage box 10 from leaking from the connected portion 18.

As shown in fig. 3 to 5, the storage box 10 is opened upward by a treatment agent replenishment port 10H as a rectangular opening. That is, in the present embodiment, the treatment agent replenishment port 10H for replenishing the rinsing agent R1 to the cartridge 10 is provided integrally with the cartridge 10 in the movable body 6.

As shown in fig. 4 and 5, the treatment agent replenishment port 10H is disposed on the 2 nd upper surface 72 of the door upper surface cover 77 in a state where the storage box 10 is mounted on the box body 19. In this state, the treatment agent replenishment port 10H is surrounded by the inner peripheral edge of the tank attachment hole 72H. The user interface 79 disposed on the 1 st upper surface 71 of the door upper surface cover 77 is located above and in front of the treatment agent supply port 10H.

The treatment agent supply port 10H is disposed outside the sealing region E1, more specifically, in front of the sealing region E1. As shown in fig. 2, the treatment agent supply port 10H is disposed at a position exposed to the outside of the housing 9 when the moving body 6 moves to the pulled-out position.

As shown in fig. 3, the cover 15 is detachably provided at the upper end of the storage box 10. As shown in fig. 4 and 5, the cover body 15 is a rectangular cover that is larger than the treatment agent replenishment port 10H and smaller than the case attachment hole 72H.

The cover body 15 closes the treatment agent replenishment port 10H in a state of being attached to the upper end of the storage box 10. In this state, the upper surface of the cover body 15 is substantially flush with the 2 nd upper surface 72 of the door body upper surface cover 77.

As shown in fig. 5, the cover body 15 is provided with a supply hole 15H, an opening/closing cover 15A, and grip recesses 15B and 15C.

The supply hole 15H is opened at the left end of the cover body 15 in a rectangular shape smaller than the treatment agent supply port 10H. The open/close cover 15A closes the supply hole 15H as shown by a solid line in fig. 5. The user swings the opening/closing lid 15A to the position shown by the two-dot chain line in fig. 5, and injects the rinse R1 from the supply hole 15H after opening, thereby supplying the rinse R1 to the storage box 10.

The holding recesses 15B and 15C are recessed downward at the center and right end of the upper surface of the cover 15. When the user grips grip recesses 15B and 15C and lifts cover 15, case 10 and cover 15 can be removed from box 19 integrally. As shown by the two-dot chain line in fig. 3, by removing cover 15 from storage box 10, storage box 10 and cover 15 can be cleaned appropriately.

As shown in fig. 1, the end portion of lid 8 formed on the outer side (front side) of sealing member 8S may be provided so as not to extend above cover 15 that closes treatment agent supply port 10H, or above opening/closing cover 15A that closes supply hole 15H shown in fig. 4 and 5, in a state where lid 8 closes opening 7H of cleaning tank 7. That is, the end portion of the lid body 8 formed on the outer side (front side) of the sealing member 8S is formed by: a position where the cover body 15 or the opening/closing cover 15A does not come into contact with the cover body 15 or the opening/closing cover 15A even if the cover body 15 or the opening/closing cover 15A is insufficiently attached. With this configuration, the following problems can be suppressed: when lid 8 is brought into contact with insufficiently attached cover body 15 or opening/closing lid 15A when opening 7H of cleaning tank 7 is closed, sealing member 8S is not in close contact with sealing region E1, and thus sealing of the gap between peripheral edge 7R of cleaning tank 7 and lid 8 is hindered.

Cleaning operation

In the dish washing machine 1 configured as described above, the washing operation is performed in the following order. In this embodiment, the cleaning operation includes a cleaning step, a rinsing step, and a drying step.

In order to store tableware TW1 to be washed in washing tub 7, the user moves moving member 6 to the pulled-out position shown in fig. 2 by holding handle 7G of door body protrusion 78. Then, the user accommodates tableware TW1 in washing tub 7 having opening 7H opened. Further, the user opens the open/close lid 15A of the cover body 15, injects the rinse agent R1 from the supply hole 15H, supplies the rinse agent R1 to the storage box 10, and then closes the open/close lid 15A.

At this time, the storage of dish TW1 into washing tub 7 and the replenishment of rinse agent R1 into storage box 10 do not matter at first. Then, the user operates the user interface 79 to instruct the start of the cleaning operation, and moves the moving body 6 to the pulled-out position shown in fig. 1.

Then, control unit C1 executes the cleaning operation and starts the cleaning step on condition that it is monitored by a position sensor, not shown, that cleaning tank 7 is at the storage position and that cleaning tank 7 is locked at the storage position by a lock sensor, not shown.

In the washing step, the controller 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, controller C1 automatically puts detergent into washing tub 7 in an amount corresponding to tableware TW1 contained in washing tub 7 by an automatic detergent putting device, not shown. Further, the controller C1 controls the treating agent supply device 20 in the cleaning step to: rinse agent R1 is not mixed into the water supplied into cleaning tank 7.

Controller C1 operates pump 62 to spray washing water from nozzle 61 into washing tub 7, thereby washing dishes TW 1.

When the washing step is finished, controller C1 reverses pump 62 to discharge the washing water in washing tub 7 to the outside of dishwasher 1, and then starts the washing step.

In the rinsing step, the controller C1 opens the water supply solenoid valve 69 to supply water into the cleaning tank 7 through the water supply pipe P1. At this time, the control unit C1 controls the treating agent supply device 20 to: rinse agent R1 is mixed into the water supplied into cleaning tank 7. Thus, treatment agent supply device 20 mixes rinse agent R1 into the water supplied into cleaning tank 7 while accurately measuring the amount of rinse agent R1 corresponding to tableware TW1 contained in cleaning tank 7.

Then, controller C1 operates pump 62 to spray washing water mixed with rinse agent R1 from nozzle 61 into washing tub 7 to wash tableware TW 1.

When the washing step is finished, controller C1 reverses pump 62 to discharge the washing water for washing in washing tub 7 to the outside of dishwasher 1, and then starts the drying step.

In the drying step, controller C1 appropriately operates heater 63 and drying fan 68 to send the heated air into washing tub 7 to dry tableware TW1 in washing tub 7. When the drying step is finished, the controller C1 finishes the washing operation.

In the drying step, the rinse agent R1 contained in the water droplets adhering to the tableware TW1 at the end of the rinsing step improves the water film residue of the tableware TW1, thereby making it possible to suppress the adhesion of the water droplets to the tableware TW 1. As a result, the time required for the drying step can be shortened, and generation of water marks (spots) on the dried tableware TW1 due to water droplets adhering to the tableware TW1 can be suppressed. In addition, the gloss component contained in the rinse agent R1 makes it easier to obtain gloss after the dish TW1 is washed.

Effect of action

In dishwasher 1 of the embodiment, treatment agent supply port 10H is disposed at a position not covered by dishes TW1 stored in washing tub 7, i.e., at a position outside of sealed region E1, and at a position exposed to the outside of case 9 when moving member 6 moves to the pulled-out position, as shown in fig. 2, 4, and 5. Thus, the user can easily supply rinse agent R1 from treatment agent supply port 10H to storage box 10 through supply hole 15H of cover body 15 before or after tableware TW1 is stored in washing tub 7.

Therefore, in the dishwasher of the embodiment, the convenience of the user can be improved when the rinse agent R1 is used.

In dishwasher 1, as shown in fig. 1, the washing water sprayed or scattered in washing tub 7 during the washing of dishes TW1 stored in washing tub 7 is blocked by lid 8 and sealing member 8S closing opening 7H and is less likely to reach the position outside of sealed region E1. Therefore, in the dish washing machine 1, the washing water can be reliably prevented from falling to the treatment agent replenishment port 10H or the periphery thereof and becoming dirty. In the dish washing machine 1, even when the cover body 15 is removed from the upper end of the storage box 10 to open the treatment agent supply port 10H, for example, the entry of washing water from the treatment agent supply port 10H can be reliably suppressed. As a result, the detergent components and dirt components contained in the washing water are prevented from being mixed into the rinse agent R1, and the quality of the rinse agent R1 is prevented from being degraded.

In the dish washing machine 1, as shown in fig. 4 and 5, the treating agent replenishment port 10H is disposed forward of the sealing region E1. With this configuration, since the moving distance required when the user moves the movable body 6 to the pulled-out position shown in fig. 2 to expose the treatment agent supply port 10H to the outside of the housing 9 can be shortened, the rinse agent R1 can be more easily supplied from the treatment agent supply port 10H to the storage box 1. In addition, with this configuration, it is possible to suppress with high reliability: when the movable body 6 is pulled out to the pulled-out position, water droplets and the like adhering to the back surface of the lid body 8 drop to the treatment agent supply port 10H.

In the dish washing machine 1, as shown in fig. 5, the treating agent supply port 10H is disposed: the 2 nd upper surface 72 is an upward surface between the front surface 70F of the door body 70 and the seal region E1. With this configuration, if the rinse agent R1 is more easily replenished from the treatment agent supply port 10H to the storage box 10 than in the case where the treatment agent supply port 10H is disposed on the left or right surface between the front surface 70F of the door body 70 and the seal region E1.

In the dishwasher 1, the user interface 79 having the operation instruction portion 79A and the display portion 79B is disposed: the 1 st upper surface 71 of the door body upper surface cover 77 located above the treatment agent replenishment port 10H. With this structure, even if the user puts the rinse agent R1 out of the treatment agent supply port 10H at the time of supplying the rinse agent R1, the rinse agent R1 is difficult to bypass the user interface 79. As a result, in the dishwasher 1, the user interface 79 can be reliably prevented from being soiled with the rinse agent R1.

In the dish washing machine 1, the cover body 15 that closes the treatment agent replenishment opening 10H can reliably prevent foreign matter from entering the storage box 10 from the treatment agent replenishment opening 10H.

As described above, the present invention has been described based on the embodiments, but the present invention is not limited to the embodiments described above, and can be modified and applied as appropriate within a range not departing from the gist thereof.

In the embodiment, the treatment agent is a liquid rinse agent R1, but the present invention is not limited to this structure. For example, the treatment agent may be a detergent, or may be a powder or tablet other than a liquid.

Although the treating agent replenishment port 10H is provided integrally with the cartridge 10 on the movable body 6 in the embodiment, the present invention is not limited to this configuration. For example, the treatment agent supply port may be connected to the treatment agent supply port and the storage box by piping or the like separately from the storage box.

In the embodiment, the cover body 15 for closing the treatment agent supply port 10H provided in the storage box 10 is provided, but the supply hole 15H provided in the cover body 15 may be the treatment agent supply port of the present invention and the open/close cover 15A for closing the supply hole 15H may be the cover body of the present invention.

In the embodiment, the treatment agent replenishment port 10H is disposed on the 2 nd upper surface 72 of the door body upper surface cover 77 located forward of the seal region E1, but the present invention is not limited to this configuration. For example, the following modified configurations are also included in the present invention: the treatment agent supply port 10H according to the embodiment is disposed on a surface facing upward or a surface facing lateral to the right or left of the sealing region E1, and is disposed at a position exposed to the outside of the housing 9 when the movable body 6 moves to the pulled-out position.

In the embodiment, the storage box 10 is detachably provided in the case 19, but the present invention is not limited to this configuration. For example, the following structures are also included in the present invention: the case body 19 is removed from the embodiment, and the connected portion 18 of the storage case 10 is fixed to the connection pipe 28 of the treating agent supplying device 20 so that the storage case 10 cannot be attached and detached.

The present invention can be used for, for example, a dish washing machine, a dish washing and drying machine, a kitchen appliance, or the like.
