Depending on the amount of material 6 to be cleaned, more than one dish basket may be provided. Moreover, although the tableware cage 7 and the mounting part 8 were demonstrated by the example comprised by the metal wire rod above, it is not restricted to this. For example, the tableware cage 7 and the placement unit 8 may be made of metal coated with a material such as nylon or a resin material such as polypropylene (PP).

As described above, the outline of the dishwasher 1 of the present embodiment is configured.

Next, the internal configuration of the dishwasher 1 will be described using FIGS. 2 and 3.

FIG. 2 is a side cross-sectional view of the state where the door 4 of the dishwasher 1 in the same embodiment is pulled forward. FIG. 3 is a side sectional view of the state where the door 4 of the dishwasher 1 in the embodiment is closed.

As shown in FIGS. 2 and 3, a washing nozzle 10 which is a washing unit (treatment unit) for washing the object to be washed 6 is provided below the dish cage 7. The cleaning nozzle 10 is rotatably provided substantially at the center (including the center) when the dish cage 7 is viewed from above, and is connected to the water conduit 12. The cleaning nozzle 10 has a hollow space through which cleaning water flows, and is provided with one or more injection holes 10 a on the upper surface. The injection holes 10 a inject cleaning water toward the object 6 on the tableware cage 7. At this time, the washing nozzle 10 rotates in the direction opposite to the jetting direction of the washing water by the reaction force generated when the washing water supplied from the water conduit 12 is jetted from the injection holes 10a.

In addition, although the structure which provides the injection hole 10a only in the upper surface of the washing | cleaning nozzle 10 was demonstrated to the example above, it is not restricted to this. For example, an injection hole may be further provided below the cleaning nozzle 10. Thereby, after washing | cleaning, washing water can be discharged | emitted from the lower injection hole, and retention of the washing water in the washing nozzle 10 can be prevented.

The water conduit 12 is formed in the shape of a hollow pipe. The water conduit 12 extends in a substantially horizontal front-rear direction (including the horizontal front-rear direction), and is formed to bend downward above the cleaning nozzle 10.

The water conduit 12 is fixed to the lower wire 7 c of the tableware cage 7 and moves in the front-rear direction with the tableware cage 7. When the water conduit 12 moves forward, the connection between the rear end of the water conduit 12 and the pipe-shaped joint 13 fixed to the back surface of the washing tank 3 is released. When the tableware cage 7 and the water conduit 12 move rearward, the rear end of the water conduit 12 joins with the joint 13. Thereby, water supply to the cleaning nozzle 10 is possible.

The tableware cage 7 is provided above the cleaning nozzle 10, as viewed from above, substantially in the entire cleaning space 5. The tableware cage 7 is supported movably in the front-rear direction by a pair of tableware rails 14 on the left and right sides of the tableware cage 7. The dish cage rail 14 is held on the lower side of both the left and right inner side walls 3 e and 3 f of the washing tank 3. This enables the tableware 7 to be pulled out from the front opening 2 to the front of the washing tank 3.

Further, the placement unit 8 on which the user places the object 6 to be cleaned is disposed above the dish cage 7. The front portion of the placement unit 8 is fixed to the door 4.

The mounting unit rail 17 is held on the upper side of the inner side walls 3 e and 3 f of the cleaning tank 3. Thus, the placement unit 8 can be pulled out of the front opening 2 to the front of the cleaning tank 3.

In addition, you may provide the pin etc. which hold the to-be-cleaned object 6 in the mounting part 8. FIG. Thereby, the role of the tableware basket can be given to the mounting portion 8 so that the object 6 can be cleaned. In addition, a part of the tableware basket 7 may be used as the placement unit. This makes it possible to provide a space for placing the objects to be cleaned 6 in the tableware cage 7.

In addition, at the lowermost portion of the cleaning space 5 of the cleaning tank 3, for example, a recessed drainage port 30 is provided. The washing water pump 18 is disposed on the lower side outside the bottom surface of the washing tank 3. The pump water channel 31 constitutes a path connecting the drainage port 30 and the flush water pump 18.

The cleaning water pump 18 supplies cleaning water for cleaning the object to be cleaned 6 to the cleaning nozzle 10 via the cleaning water passage 32, for example, during forward rotation. The washing water supplied from the washing water pump 18 passes through the washing water passage 32 and is sent to the washing nozzle 10 through the joint portion 13. On the other hand, at the time of reverse rotation, the washing water pump 18 switches the valve and drains the washing water in the washing tank 3 after washing is finished to the outside of the dishwasher 1.

In addition, although the example which performs circulation of the washing water to the inside of the washing tank 3 and drainage of the washing water to the outside of the washing tank 3 by the example which performs one wash water pump 18 above, it is not restricted to this. For example, circulation and drainage of washing water may be separately performed using two dedicated pumps.

Moreover, the dishwasher 1 of the present embodiment further includes a main tray 20 and an auxiliary tray 21. The main tray 20 and the auxiliary tray 21 receive water droplets and the like falling from the objects to be cleaned 6 placed on the tableware cage 7 and the placement unit 8. The main tray 20 and the auxiliary tray 21 are pulled forward together with the door 4. At this time, the main tray 20 and the auxiliary tray 21 are disposed with a gap between the left inner wall 3 e and the right inner wall 3 f of the cleaning tank 3. Thereby, the main tray 20 and the auxiliary tray 21 can be smoothly taken in and out with the door 4 with respect to the cleaning tank 3.

The main tray 20 is disposed below the tableware basket 7 and is formed in a shape having a larger width dimension in the left-right direction than the tableware basket 7 when viewed from the top of the tableware basket 7. The main tray 20 is disposed inside the cleaning space 5 when the door 4 is closed.

The auxiliary tray 21 is disposed below the main tray 20. The auxiliary tray 21 is disposed at a position outside the washing space 5 below the washing tank 3 when the door 4 is closed. When the door 4 is pulled out, the auxiliary tray 21 is disposed so that the distance in the height direction between the auxiliary tray 21 and the main tray 20 is at least 3 cm or more, preferably 5 cm or more. The interval of 3 cm or more is, for example, in consideration of insertion of the user's hand, and is not limited to this. Thereby, the main tray 20 and the like can be easily removed and attached.

Specifically, the main tray 20 is formed in a concave shape that opens upward, and is formed of a resin material such as PP having high rigidity. The main tray 20 is disposed to be inclined downward (for example, an inclination angle of 5 degrees) toward the rear. The front end portion of the main tray 20 is detachably fixed to the main tray claw portion 20 a provided on the door 4 by claw fitting.

The inclination of the main tray 20 may be formed at least on the upper surface side of the bottom. Furthermore, if it is formed also on the lower surface side (back surface) of the bottom portion, it is more preferable because it flows down to the cleaning tank 3 side and drops even if water droplets adhere to the lower surface side.

Further, the inclination of the main tray 20 may be configured by inclining and positioning the main tray 20 downward toward the rear when the front end portion of the main tray 20 and the door 4 are fixed.

In the above, the configuration in which the inclination of the main tray 20 has a constant inclination angle has been described as an example, but the present invention is not limited to this. For example, the rearward and downward inclination of the main tray 20 may be configured to have a plurality of inclination angles. In addition, the inclination of the main tray 20 may be configured by an inclination angle which changes gradually and continuously.

Further, the main tray 20 is provided with tray rollers 23 (rolling support portions) rotatably provided on the left and right of the rear end portion. The tray roller 23 supports the main tray 20 while rolling on the upper surfaces of the tray rails 24 provided on the left and right inner side walls 3 e and 3 f of the cleaning tank 3. That is, when the door 4 is pulled out, the main tray 20 is supported by the tray roller 23 and pulled out together with the door 4.

The auxiliary tray 21 is composed of a first auxiliary tray 21a and a second auxiliary tray 21b provided below the first auxiliary tray 21a. The first auxiliary tray 21a and the second auxiliary tray 21b are formed in a concave shape that opens upward, and are formed of a resin material such as PP having high rigidity. The first auxiliary tray 21a and the second auxiliary tray 21b are arranged to overlap vertically in the state where the door 4 is closed. On the other hand, when the door 4 is pulled out, the first auxiliary tray 21a and the second auxiliary tray 21b are pulled out together with the door 4 while being displaced relative to each other in the front-rear direction.

Moreover, the dishwasher 1 of this Embodiment is equipped with the seal | sticker part 25 continuously provided along the square-shaped outer periphery in the surface (inner surface) by the side of the washing tank 3 of the door 4. As shown in FIG. The seal portion 25 is formed in a hollow shape, for example, with silicone rubber. The seal portion 25 incorporates, for example, a rubber magnet (not shown) or the like having a magnetic force on the surface on the cleaning tank 3 side. On the other hand, the cleaning tank seal surface 26 of the cleaning tank 3 facing the seal part 25 is made of a metal such as SUS 430 having magnetism. Therefore, when the door 4 is closed from the pulled out state, the seal portion 25 is drawn to the cleaning tank seal surface 26 by the magnetic force. Thereby, the door 4 is closed with respect to the cleaning tank 3 while maintaining water tightness.

That is, after the seal portion 25 is drawn into the cleaning tank sealing surface 26, the entire surface of the sealing portion 25 is attracted by the cleaning tank sealing surface 26 and the magnetic force, and the cleaning tank 3 is sealed. Thereby, even if some deformation due to the warp of the door 4 or the cleaning tank seal surface 26 or the like, or the forward collapse of the door 4 occurs, the sealing performance during the cleaning of the cleaning tank 3 can be secured. As a result, water leakage from the cleaning space 5 to the outside can be prevented.

In addition, although the structure which provides the sealing part 25 continuously to square shape was demonstrated to the example above, it is not restricted to this. As long as the sealing performance between the door 4 and the cleaning tank 3 can be ensured, for example, a seal part in which a part of the connection is broken may be formed.

Moreover, although the example which comprises the washing tank sealing surface 26 by SUS430 was demonstrated above, it is not restricted to this. A material having magnetism, such as iron, may be used. Further, the front surface of the cleaning tank 3 other than the cleaning tank sealing surface 26 may be made of a nonmagnetic material such as PP resin.

Moreover, although the structure which provides the seal | sticker part 25 in the door 4 side was demonstrated to the example in the above, it is not restricted to this. For example, the seal portion may be provided on the cleaning tank 3 side, and a material having magnetism may be disposed on the surface of the facing door 4.

Furthermore, as shown in FIG. 2, the cleaning tank 3 of the present embodiment is provided with a receiving portion 27 opened upward at the bottom on the front side. At this time, the cleaning tank seal surface 26 is disposed rearward of the front surface 3 a of the receiving portion 27 of the cleaning tank 3. Thus, the receiving portion 27 receives the cleaning water flowing downward along the cleaning tank sealing surface 26. Further, when the door 4 is suddenly pulled out during cleaning, the receiving portion 27 is from the gap between the seal portion 25 of the door 4 and the cleaning tank sealing surface 26 until the cleaning water pump 18 is stopped. It receives cleaning water that flows down along the cleaning tank sealing surface 26. That is, even if some washing water flows down, the washing water can be received by the receiving portion 27 to prevent overflowing to the lower side.

In addition, a hole 26 a is partially provided in the lower cleaning tank seal surface 26. The holes 26 a return the cleaning water accumulated in the receiving portion 27 into the cleaning tank 3. As a result, it is possible to prevent the washing water from falling to the installation surface or the like as it overflows from the receiving portion 27.

Further, as shown in FIG. 2 and FIG. 3, the door 4 is provided with a key-shaped hook 28 on the inner wall on the cleaning space 5 side. The hooks 28 are engaged with a wire substantially at the center (including the center) of the front of the dish cage 7. By the engagement, the door 4 and the tableware cage 7 can move back and forth interlockingly. When the tableware basket 7 is removed, the user lifts the wire at the front of the tableware basket 7. As a result, the engagement between the wire and the hook 28 is released, and the tableware cage 7 can be removed.

The hook 28 has an integrally provided inclined surface 28 a which is inclined rearward. As a result, even when the door 4 is pulled forward and the tableware cage 7 is removed from the hook 28 and disposed in the cleaning tank 3, as the door body 4 is closed, the front side of the tableware cage 7 is The wire lifts along the inclined surface 28 a of the hook 28. Then, when the door 4 is closed, the wire at the front of the dish cage 7 engages with the hook 28. Thus, next time the door 4 is pulled forward, the tableware 7 is also pulled out simultaneously with the door 4.

Moreover, the washing tank 3 is provided with the water supply valve 29 directly connected with the water supply at the upper rear. Thus, the tap water is supplied as water to the cleaning tank 3 through the water supply valve 29.

The cleaning tank 3 is provided with a fan 33 at the rear lower side of the outside. When driven, the fan 33 sucks external air in the drying step of the dishwasher 1 or the like. The sucked air is supplied to the inside of the cleaning space 5 from the air blowing port 35 through the air blowing path 34. The air supplied to the cleaning space 5 is warmed by the heater 36 disposed below the cleaning space 5. The warmed air is supplied into the cleaning space 5 to dry the object 6 to be cleaned inside. Then, the air is exhausted to the outside from an exhaust port 37 provided on the upper surface or the side wall of the door 4. In addition to the above, the exhaust port 37 may be provided on the top surface or the side wall of the cleaning tank 3.

A temperature detection unit 38 is disposed in close contact with the outer side of the bottom of the cleaning tank 3. The temperature detection unit 38 indirectly detects the temperature of the cleaning water, the air, and the heater 36 in the cleaning tank 3.

The control unit 40 is disposed below the bottom surface of the cleaning tank 3. The control unit 40 controls the water supply valve 29 based on a signal from the operation unit 9 operated by the user to control the supply of the cleaning water into the cleaning tank 3. Further, the control unit 40 controls the heater 36 based on the output of the temperature detection unit 38. Furthermore, the control unit 40 controls the washing water pump 18, the fan 33 and the like to sequentially execute a series of steps such as washing, rinsing and drying.

Further, the control unit 40 according to the present embodiment analyzes shooting information obtained by the hand camera 103 and the fixed camera 104 described later. The control unit 40 controls the transfer device 100 based on the analysis result of the imaging information. The specific control of the transfer device 100 will be described later.

Further, as shown in FIG. 2, a door drive motor 70, which is an opening and closing device for opening and closing the door 4, is provided at the front bottom of the cleaning tank 3 and below the bottom surface.

The acceleration sensor 71 is provided inside the door 4. The acceleration sensor 71 detects an impact applied to the door 4 when the door 4 is closed, for example, when it is struck by the user's hand. The control unit 40 receives the detection information from the acceleration sensor 71 and drives the door drive motor 70. As a result, the door 4 moves forward, and the cleaning tank 3 is opened. Similarly, when the acceleration sensor 71 detects an impact applied to the door 4 while the door 4 is open, the control unit 40 receives the detection information and drives the door drive motor 70. As a result, the door 4 moves rearward and closes the front opening 2 of the cleaning tank 3.

The door detection switch 72 is provided on the upper side of the auxiliary tray 21 in front of the lower side of the bottom surface of the cleaning tank 3. The door detection switch 72 constitutes an open / close detection unit that detects the opening / closing of the door 4. The control unit 40 controls the rotation direction of the door drive motor 70 based on the detection information of the door detection switch 72. Thereby, the opening and closing operation of the door 4 is properly performed.

In addition, although the example which uses the acceleration sensor 71 as an information source (trigger) which starts opening-closing operation of the door 4 was demonstrated above, it is not restricted to this. For example, information from an electrostatic sensor that recognizes a change in capacitance, a microphone that recognizes voice, or the like may be used as a trigger that starts the opening / closing operation of the door 4.

Moreover, although the door drive motor 70 demonstrated the example which has both functions which open and close the door 4 in the above, it is not restricted to this. The door drive motor 70 may be configured to have one of the functions of, for example, opening the door 4 or closing the door 4.

The above-described transfer device 100 is disposed, for example, on the inner rear surface 3 g of the cleaning tank 3 and has a function of transferring the object 6 to be cleaned.

As a result, the occurrence of a failure of the fixed camera 104 can be prevented in advance. Furthermore, the fixed camera 104 may be configured to be driven to oscillate by a motor or the like. As a result, the inside of the cleaning tank 3 can be photographed entirely by the fixed camera 104 so that no dead angle occurs.

Further, although the configuration in which the object to be cleaned 6 is gripped by the pair of grips 102 a of the hand 102 has been described above as an example, the present invention is not limited thereto. For example, the object to be cleaned 6 may be suctioned and held using a suction pump or the like. Furthermore, without using the transfer apparatus 100 of the said structure, you may use the transfer apparatus of a different form, such as a belt conveyor and an elevator, for example.

As shown in FIG. 2, a sheet-like cover 107 is provided to cover the whole of the transfer device 100 according to the present embodiment. The cover 107 is waterproofed to prevent a short circuit of the electrical part generated by the washing water applied to the transfer device 100. The cover 107 incorporates a pressure sensor that functions as a pressure detection unit. The pressure sensor detects the pressure when the transfer device 100 is externally pressurized. Specifically, the pressure sensor detects, for example, that a human has touched the transfer device 100. The control unit 40 stops the operation of the transfer device 100 based on the detection signal of the pressure sensor at the time of contact. In this way, safety for human beings and damage to the transfer device 100 can be prevented in advance.

As described above, the transfer device 100 is configured and operates.

Hereinafter, the control operation of the control unit 40 in the dishwasher 1 as an example of the dish processing machine according to the present embodiment will be specifically described.

First, when the user tries to open the door 4 with a hand or the like to open the door during cleaning, the control unit 40 stops the cleaning water pump 18 if cleaning is in progress for safety. Similarly, when trying to open the door 4 during drying, the control unit 40 stops the fan 33 and the heater 36.

In addition, when the door 4 is to be opened during operation of the transfer device 100, the control unit 40 moves the transfer device 100 to a position where the object to be cleaned 6 or the dish cage 7 in the cleaning tank 3 does not hit. Operate and stop. Thereafter, the control unit 40 operates the door drive motor 70 to move the door 4 forward. In this case, after returning the transfer device 100 to the initial position and stopping it, the control unit 40 operates the door drive motor 70 to move the door 4 and control the cleaning tank 3 to be opened. Is preferred. Thereby, after movement of the door 4, the user can easily take out the object to be cleaned 6 from the cleaning tank 3 without being disturbed by the transfer device 100.

That is, it is possible to prevent the occurrence of the problem of the washing water scattering to the user due to the careless opening of the door 4 and the trouble due to the warm air. Furthermore, the occurrence of breakage or the like due to the contact between the transfer device 100 and the object to be cleaned 6 can be prevented in advance.

As mentioned above, control part 40 of dishwasher 1 of this embodiment controls operation of each part.

Further, as shown in FIG. 2, the door detection switch 72 is provided on the upper side of the auxiliary tray 21 in front of the lower side of the bottom surface of the cleaning tank 3. The door detection switch 72 detects that the door 4 is closed. When the door 4 is opened, the control unit 40 receives the detection information from the door detection switch 72 and controls the washing water pump 18 to stop so that the washing water does not jump out of the washing tank 3 during washing. Do.

Specifically, when the door detection switch 72 detects that the door 4 is open, the control unit 40 stops the washing water pump 18 if it is being washed. Similarly, during drying, the control unit 40 stops the fan 33 and the heater 36. If the transfer device 100 is in operation, the control unit 40 stops the transfer device 100. This makes it possible to prevent the occurrence of problems and ensure safety.

In addition, although the structure which opens and closes the door 4 by the door drive motor 70 was demonstrated to the example above, it is not restricted to this. For example, a handle or the like may be provided on the door 4, and the user may manually open and close the door 4 via the handle. In this case, it is desirable to provide a door lock device (not shown). The door lock device locks the door 4 so as not to open when the door 4 is closed. That is, the control unit 40 locks the door 4 so that the door 4 is not opened by the door lock device during cleaning, drying, and operation of the transfer device 100. In this way, the door 4 can be prevented from being unexpectedly opened by the operation of the handle, and safety can be ensured.

On the other hand, when the user wants to open the door 4 in the locked state, the user presses a lock release button (not shown). Thereby, the control unit 40 stops the washing water pump 18 if cleaning is in progress, stops the fan 33 and the heater 36 if drying, and stops the transfer device 100 if the transfer device 100 is in operation. . Then, the control unit 40 operates the door lock device to release the lock of the door 4. In this state, the user can open the door 4. In this case, after the control unit 40 returns the transfer device 100 to the initial position and stops, the control unit 40 preferably releases the door lock device so that the user opens the door 4. As a result, after the door 4 is opened, the user can easily take out the object 6 without being disturbed by the transfer device 100.

As described above, in the present embodiment, the door lock device or the like is used to lock the door 4 so as not to open during the operation of the transfer device 100. Thus, the user can not open the door 4 during cleaning, drying and operation of the transfer device 100. As a result, it is possible to prevent the occurrence of a failure due to the contact between the user and the transfer device 100 or the like.

The door lock device may be applied to a dishwasher configured to open and close the door 4 by the door drive motor 70. In this case, even if the door drive motor 70 malfunctions and tries to open the door 4, the door lock device locks the door 4 and does not open it. Therefore, the occurrence of a collision with the door 4 due to the opening can be prevented, and the safety of the user can be secured. Further, in operation, the water tightness between the front opening 2 of the cleaning tank 3 and the door 4 can be maintained. Thereby, scattering of the washing water to the outside of the dishwasher 1 and falling to the floor surface can be prevented.

Hereinafter, the operation and action of the dishwasher 1 having the above-described configuration will be described with reference to FIGS. 4 and 5.

FIG. 4 is a side sectional view showing the position of the transfer device 100 when the transfer device 100 of the dishwasher 1 according to the embodiment holds the object 6 to be cleaned. FIG. 5 is a side sectional view showing the position of the transfer device 100 when the transfer device 100 of the dishwasher 1 in the embodiment arranges the object 6 to be cleaned.

First, in a state where the door 4 of the dishwasher 1 closes the front opening 2, the user taps the door 4 from the front, for example, with a hand. At this time, the acceleration sensor 71 detects an impact (acceleration) received by the door 4. The control unit 40 receives the detection information from the acceleration sensor 71, drives the door drive motor 70, and pulls the door 4 forward. At this time, the tableware cage 7 engaged with the door 4 by the hook 28, the placement unit 8, the main tray 20 and the auxiliary tray 21 are pulled forward in conjunction with the door 4.

Next, the user places, for example, the objects to be cleaned 6 on the placement unit 8 in a stacked state, and places the detergent into the cleaning tank 3. Then, the user inputs a cleaning and drying course, conditions, and the like through the operation unit 9 on the upper surface of the door 4.

Next, the user presses the power button and the start button. Then, again, the user strikes the door 4 from the front, for example, with a hand. The acceleration sensor 71 detects an impact received by the door 4. The control unit 40 receives the detection information from the acceleration sensor 71, drives the door drive motor 70, moves the door 4 rearward, and closes the front opening 2. FIG. 4 shows the situation of the dishwasher 1 with the front opening 2 closed.

Next, when the door detection switch 72 detects that the door 4 is closed, the control unit 40 captures an image of the cleaning object 6 in the cleaning tank 3 using the hand camera 103 and the fixed camera 104. Then, the control unit 40 automatically recognizes the position, the shape, the quantity, the material, the type, and the color of the object 6 to be cleaned, and the attached matter and the like attached to the object 6 from the photographed data.

Thereafter, based on the recognized result, the control unit 40 brings the transfer device 100 closer to the object 6 on the placement unit 8, the method of gripping the object 6, the method of transferring the object 6 and the object 6. Make a plan (procedure), such as how to arrange the items to be washed 6 in the dish cage 7.

Next, the control unit 40 executes the transfer and arrangement of the cleaning object 6 from the placement unit 8 to the tableware cage 7 according to the following procedure in accordance with the established plan (procedure).

First, the control unit 40 controls the driving of the transfer device 100 according to the shape, the number, and the like of the objects to be cleaned 6 disposed in the tableware cage 7. Specifically, the transfer device 100 performs erecting of movable pins (not shown) for holding the objects 6 to be cleaned provided on the tableware cage 7 and folding of the movable pins.

Next, the control unit 40 brings the hand 102 of the transfer device 100 closer to a position where the object to be cleaned 6 stacked on the placement unit 8 can be gripped. At this time, the control unit 40 controls the first arm 100 a to the fourth arm 100 d of the transfer device 100 so as not to hit the object to be cleaned 6 other than the grip, the washing tank 3, and the placement unit 8. The hand 102 is brought closer while adjusting the angle etc. of the third joint 101 c from the joint 101 a.

Next, the control unit 40 opens and closes and rotates the pair of grips 102 a of the hand 102 to grip the uppermost cleaning object 6 on the placement unit 8. At this time, the control unit 40 determines an appropriate gripping position (the edge of the object 6 to be cleaned, etc.) based on information such as the position, the shape, the material, the type, the attached matter, and the distance to the other object 6 Determine the sides, handles, etc.) and how to grip (pick, hold etc). Specifically, the control unit 40 controls the first arm 100 a to the fourth arm 100 d and the first joint portion 101 a so as not to hit the other wash target 6, the washing tank 3, and the placement unit 8. The hand 102 is operated while adjusting the angle of the third joint portion 101c.

Next, the control unit 40 moves the transfer device 100 to the appropriate arrangement position on the dish cage 7 with the object 6 gripped by the hand 102. At this time, the control unit 40 controls the first arm 100 a to the fourth arm 100 d of the transfer device 100 so as not to hit the object to be cleaned 6 other than the grip, the washing tank 3, the placement unit 8, and the dish cage 7. , And the transfer device 100 is driven while adjusting the angle and the like of the first joint portion 101a to the third joint portion 101c.

Next, when moving to the position of the dish cage 7 in which the object 6 to be cleaned is disposed, the control unit 40 opens the handle 102 a of the hand 102. As a result, the griped object 6 is released from the hand 102, and the object 6 is placed at the planned position on the tableware cage 7. At this time, the control unit 40 controls the first arm 100 a to the fourth arm 100 d and the other so as not to hit the object to be cleaned 6 other than the grip, the washing tank 3, the placement unit 8, and the dish cage 7. The hand 102 is operated while adjusting the angle and the like of the first joint portion 101a to the third joint portion 101c.

Next, the control unit 40 controls driving of the transfer device 100 in the same manner as described above. As a result, the objects to be cleaned 6 stacked on the placement unit 8 are moved from the top to the appropriate position of the tableware cage 7 and arranged.

At this time, the control unit 40 according to the present embodiment arranges the object to be cleaned 6 through the transfer device 100 basically based on the method described below.

Specifically, first, the to-be-cleaned object 6 is disposed preferentially from a distant position (near the door 4) away from the transfer device 100. That is, the object to be cleaned 6 is transferred and disposed at a position away from the transfer device 100. Therefore, contact with other objects to be cleaned 6 disposed near the transfer device 100 is unlikely to occur. Thereby, damage due to contact or the like between the objects to be cleaned 6 can be prevented in advance.

Specifically, large objects to be cleaned 6 (for example, cooking utensils such as large dishes, pans and pans) and fragile objects to be cleaned 6 (for example, glass dishes etc.) are separated from the transfer device 100 of the tableware basket 7 It arranges sequentially from the distant position. Then, toward the vicinity of the transfer device 100, the smaller object to be cleaned 6 is disposed gradually. As a result, contact between the transferred and disposed object 6 and the other object 6 is less likely to occur. Therefore, it is possible to prevent damage to the object 6 to be cleaned such as particularly fragile glass dishes. In addition, when the kind, quantity, etc. of the whole to-be-cleaned object 6 are small, for example, it is not necessary to arrange especially as mentioned above.

Also, when the objects to be cleaned 6 are stacked and placed on the placement unit 8, the large objects to be cleaned 6 are generally placed on the lower side. Therefore, it is difficult to first grasp and transfer the large cleaning object 6 using the transfer device 100.

In this case, the control unit 40 first detects the state of the cleaning object 6 stacked on the placement unit 8 by the hand camera 103 or the fixed camera 104. Then, the control unit 40 recognizes the size of the cleaning object 6 and the positional relationship between the upper and lower sides.

Next, based on the recognition result, the control unit 40 drives and controls the transfer device 100 to move the small object 6 stacked on the upper side to the empty space of the placement unit 8 and the dish cage 7 temporarily. Let me put it on a temporary basis. Then, as described above, the control unit 40 transfers the large object to be cleaned 6 to a distant position of the dish cage 7 away from the transfer device 100 first. Thereafter, the control unit 40 drives and controls the transfer device 100 so as to transfer the temporarily placed small cleaning object 6. According to this method, the relatively large object to be cleaned 6 is transferred and placed first. Therefore, the contact between the large object 6 to be cleaned and the other object 6 to be cleaned is unlikely to occur. Thereby, breakage of the to-be-cleaned object 6 can be prevented. However, this is not the case depending on the availability of temporary space.

Moreover, when there is a deposit on the object to be cleaned 6, the object to be cleaned 6 may be arranged based on the method described below.

First, the control unit 40 recognizes the attached matter of the object to be cleaned 6 by the hand camera 103 or the fixed camera 104. At this time, the control unit 40 determines whether a deposit that is difficult to clean adheres to the cleaning object 6 or not. If it is determined that the object 6 to be cleaned has adherent matter that is difficult to clean, the control unit 40 controls the object to be cleaned where the cleaning water from the injection hole 10a directly strikes the adherent matter. Arrange six. Therefore, it becomes easy to drop the adhering matter of the to-be-cleaned object 6 which is hard to drop. Thereby, the to-be-cleaned object 6 to which the attachment which is hard to wash adheres can be wash | cleaned efficiently.

When the material of the object to be cleaned 6 is different, the object to be cleaned 6 may be arranged based on the method described below.

First, the control unit 40 recognizes the material of the cleaning object 6 by the hand camera 103 or the fixed camera 104. At this time, the control unit 40 determines whether the material of the to-be-cleaned object 6 is the to-be-cleaned object 6 that is hard to dry, such as plastic dishes having a smaller heat capacity than pottery. If it is determined that the cleaning target 6 is a material that is difficult to dry, the control unit 40 places the recognized cleaning target 6 directly on the place of the tableware basket 7 where the warm air from the air outlet 35 hits directly. Deploy. Thereby, the to-be-washed | cleaned material 6 like a plastic which is hard to dry can be dried efficiently.

Further, the object to be cleaned 6 may be arranged based on the method described below according to the shape or type of the object to be cleaned 6.

First, the control unit 40 recognizes the shape or the type of the cleaning object 6 by the hand camera 103 or the fixed camera 104. At this time, the control unit 40 determines whether or not the cleaning target 6 has the same shape or the same type. If it is determined that the objects 6 to be cleaned have the same shape or the same type, the control unit 40 controls the transfer device 100 to move the objects 6 to be cleaned together in the vicinity of the same location of the dish cage 7. ,Deploy. Thereby, the user can take out the to-be-cleaned object 6 of the same shape or the same kind from the same place vicinity, and can store it after washing | cleaning of the to-be-cleaned object 6. FIG. Therefore, the object 6 can be taken out and stored in a short time. Furthermore, the to-be-cleaned object 6 which provides cooking can be recognized easily.

Furthermore, depending on the shape, type, or color of the object to be cleaned 6, the object to be cleaned 6 may be arranged based on the method described below.

First, the control unit 40 recognizes the shape, type, or color of the cleaning object 6 by the hand camera 103 or the fixed camera 104. At this time, the control unit 40 determines, for example, whether the tableware used by the father, the tableware used by the mother, and the tableware used by the child. When the control unit 40 determines that the tableware used by the father, the tableware used by the mother, and the tableware used by the child, the objects to be cleaned 6 are grouped according to each member of the family to be used. Move, place. As a result, when cleaning of the object to be cleaned 6 is completed, the user can efficiently take out the object to be cleaned 6 together with the members of the family and store it in the cupboard. Furthermore, food can be efficiently provided and provided to the objects to be cleaned 6 organized for each family member.

As described above, the tableware processing apparatus according to the present embodiment can appropriately arrange the object to be cleaned 6 in the tableware cage 7 based on the captured data captured by the hand camera 103 or the fixed camera 104.

In addition, the priority regarding the setting position to the dish cage 7 of the to-be-cleaned object 6 mentioned above is preset at the time of the shipment from a factory. However, the dishwasher 1 of the present embodiment can be configured to be reset by the user using the operation unit 9. Thereby, the to-be-cleaned object 6 can be set to the dish cage 7 with a priority of preference according to the user's use actual condition. As a result, a versatile dishwasher 1 can be realized.

Further, in the dishwasher 1 of the present embodiment, an obstacle other than the to-be-cleaned object 6 is initially placed on the tableware cage 7, and when the to-be-cleaned object 6 is moved from the placement unit 8 to the tabletop cage 7. When the obstacle gets in the way, the control unit 40 may process the obstacle based on the method described below.

First, the control unit 40 recognizes with the hand camera 103 or the fixed camera 104 whether or not an obstacle other than the cleaning object 6 is present on the tableware cage 7. At this time, when it is determined that an obstacle other than the object to be cleaned 6 is present on the tableware cage 7, the control unit 40 drives the transfer device 100 and grips the recognized obstacle with the hand 102. Then, it repositions the grasped obstacle out of the way. Thereby, obstacles other than the to-be-cleaned object 6 can be removed from the top of the tableware cage 7 and can be washed.

In the case where an object other than the cleaning object 6 or an object which can not be washed by the dishwasher is placed in the cleaning tank 3, the control unit 40 may perform processing based on the method described below.

First, the control unit 40 recognizes whether an object other than the object to be cleaned 6 or an object which can not be washed by the dishwasher 1 is placed in the cleaning tank 3 by the hand camera 103 or the fixed camera 104. In addition, an object which can not be washed corresponds to, for example, an electric appliance or a plastic tableware having a low heat resistance temperature. At this time, when the control unit 40 determines that the object is present, the control unit 40 notifies the user by sound or display via a notification unit (not shown). Then, the user is prompted to remove the corresponding object. Thus, it is possible to remove an object other than the object to be cleaned 6 or an object which can not be washed by the dishwasher 1 from the top of the dish cage 7 and to perform the washing process. As a result, it is possible to prevent the breakage of the object to be cleaned 6 and the deformation of the object that can not be cleaned which are generated by the contact of the object to be cleaned 6 with the object during cleaning.

Further, as described above, the dishwasher 1 of the present embodiment is configured to be able to specify the arrangement position of the to-be-cleaned object 6 in the dish cage 7 by the input from the operation unit 9. According to this configuration, the user can place the to-be-cleaned object 6 at a desired position of the dish cage 7. For example, the to-be-cleaned object 6 can be arranged at a position easy to be taken by the user according to the height, the physical constitution and the like. Further, the object to be cleaned 6 can be arranged at an easy-to-get position according to the user's handedness. This improves the convenience for the user.

As exemplified above, the control unit 40 can automatically arrange the object 6 to be cleaned through the transfer device 100 according to the state and condition of the object 6 to be cleaned.

Then, when the automatic arrangement of the cleaning object 6 by the transfer device 100 is finished, the control unit 40 returns the transfer device 100 to the initial position at the rear of the inside of the cleaning tank 3.

Next, the dishwasher 1 starts the washing and drying operation.

In the following, the flow of the washing water will be described mainly with reference to FIG. 6 for the operation of the washing and drying step.

FIG. 6 is a side sectional view showing the flow of washing water in the washing step of the dishwasher 1 in the embodiment.

First, the control unit 40 drives the washing water pump 18. Thus, the washing water remaining inside the washing tank 3 is discharged to the outside of the dishwasher 1 when the previous operation is completed.

Next, the control unit 40 opens the water supply valve 29. Thereby, a predetermined amount of tap water is supplied to the inside of the washing tank 3 as washing water. When a predetermined amount of cleaning water is supplied into the cleaning tank 3, the cleaning water flows into the inside of the cleaning water pump 18 connected to the pump water channel 31 from the drainage port 30 together with the detergent. Then, the washing water is pressurized by the washing water pump 18. Thereby, the washing water in which the detergent is dissolved is sent to the washing nozzle 10 through the washing water passage 32, the connecting part 13 and the water guiding passage 12 as shown by the arrow A in FIG.

Next, as indicated by the arrow K, the washing water supplied to the washing nozzle 10 is sprayed upward from the injection holes 10 a of the washing nozzle 10 toward the to-be-cleaned object 6 contained in the dish cage 7. At this time, the washing nozzle 10 rotates in the direction opposite to the jetting direction of the washing water by using the reaction force of the washing water jetted from the jet holes 10a. As a result, the wash water is evenly sprayed onto the stored object 6 to be cleaned.

Then, most of the washing water that has washed the object to be washed 6 falls onto the main tray 20 and flows along the downward slope toward the rear as shown by the arrow B. At this time, first, rough residual vegetables are roasted by the tray filter 41 (see FIG. 6). Furthermore, fine residual vegetables are spoiled by the drainage filter 50. Thereafter, the washing water from which the remnants are drained is collected at the drainage port 30, and flows into the washing water pump 18 again via the pump water channel 31.

As described above, the washing water in which the detergent is dissolved circulates. Thereby, the cleaning step of cleaning the object to be cleaned 6 is performed.

In the cleaning step, the control unit 40 energizes the heater 36 provided inside the cleaning tank 3 to heat the cleaning water to a predetermined temperature while circulating the cleaning water. A wash step is then performed with the heated wash water.

Usually, the washing step is performed for a predetermined time set in advance before the washing and drying operation.

However, in the dishwasher 1 according to the present embodiment, the hand camera 103 and the fixed camera 104 can monitor the deposit of the object 6 to be cleaned. Therefore, depending on the condition of the deposit, the washing step may be performed for an arbitrary time until the deposit falls below a predetermined level, and the washing may be continued. In addition, depending on the condition of the deposit, as described above, even if the object to be cleaned 6 with many deposits is transferred to a place with strong cleaning power where the cleaning water from the injection holes 10a is directly applied Good. Furthermore, the cleaning may be performed in a state in which the cleaning water is held by the hand 102 so that the adhering matter of the object to be cleaned 6 directly contacts the cleaning water.

As described above, the cleaning step is performed for a predetermined time, or for a time until the deposit of the object 6 falls below a predetermined level. Thereafter, the control unit 40 drives the washing water pump 18 to discharge the washing water including the dirt washed off from the object to be washed 6 out of the dishwasher 1.

By the above operation, when the cleaning step is finished, the control unit 40 executes the rinse step.

In the rinsing step, the control unit 40 again opens the water supply valve 29 to supply the washing water into the washing tank 3. And washing water is sprayed again from injection hole 10a of washing nozzle 10 like a washing step. Thereby, the rinse step is performed by rinsing the to-be-cleaned object 6 which has been soiled with the detergent or the residual food.

By the above operation, when the rinsing step is finished, the control unit 40 operates the washing water pump 18 to discharge the washing water out of the dishwasher 1 again. And the said rinse step is repeatedly performed several times (for example, about 2 times) continuously, and is performed.

Thereafter, when a plurality of rinse steps are completed, the control unit 40 executes a heat rinse step. Specifically, the heating and rinsing step heats the washing water to a predetermined temperature (for example, about 60 ° C.) by the heater 36, and is performed in the same operation as the above-described rinsing step.

Next, when the heating and rinsing step is completed, the control unit 40 starts the drying step.

In the drying step, first, the control unit 40 operates the fan 33. By the rotation of the fan 33, the outside air is sent from the air blowing port 35 to the inside of the cleaning tank 3 through the air blowing path 34. The air sent into the cleaning tank 3 is heated by a heater 36 provided downstream of the air outlet 35. The heated air circulates in the cleaning tank 3 to dry the object 6 to be cleaned. The dried air is exhausted out of the dishwasher 1 from the exhaust port 37. This completes the drying step.

Usually, the drying step is also performed for a predetermined time set in advance before the washing and drying operation, as in the washing step.

However, in the dishwasher 1 of the present embodiment, the dry condition of the surface of the object 6 can be monitored by the hand camera 103 and the fixed camera 104. Therefore, drying may be continued for an arbitrary time until the surface of the object to be cleaned 6 is dried. Further, depending on the degree of dryness of the surface of the object to be cleaned 6, as described above, the object to be cleaned 6 may be transferred and dried to a position where the warm air from the air outlet 35 which is easier to dry is directly applied. Furthermore, the drying process may be performed in a state in which the warm air is held by the hand 102 so as to directly hit the workpiece 6.

Next, when the drying step is completed, the control unit 40 ends the series of operations of the dishwasher 1. At this time, the control unit 40 may be configured to notify the user of the end of driving via, for example, a sound by a buzzer or the like.

Next, when the operation of the dishwasher 1 is completed, the user taps the door 4 from the front, for example, with a hand. The acceleration sensor 71 detects an impact received by the door 4. The control unit 40 receives the detection information from the acceleration sensor 71, drives the door drive motor 70, and automatically pulls out the door 4 forward. As a result, the user removes the to-be-cleaned object 6 which has been cleaned and dried from the dish cage 7.

Then, when the removal of the cleaning object 6 is completed, the user strikes the door 4 in the same manner as described above, and automatically moves the door 4 rearward. Thus, the front opening 2 of the cleaning tank 3 is closed by the door 4.

As described above, a series of washing and drying operations of the dishwasher 1 of the present embodiment are performed.

In the above-mentioned embodiment, although the arrangement process of the to-be-cleaned object 6 after the completion of the washing and drying is not particularly mentioned, for example, the kind of the to-be-cleaned object 6 The members may be divided and placed one on another. Further, after the cleaning and drying operation, the object to be cleaned 6 may be arranged on the mounting portion 8 in the same manner as the state of the object to be cleaned 6 which has been placed on the mounting portion 8 before the cleaning and drying operation. Furthermore, in the case of the configuration in which the transfer device 100 is provided outside the cleaning tank 3 described later, the transfer device 100 may be stored in the storage space of the system kitchen 11 outside the cleaning tank 3. That is, the operation of the transfer device 100 may be designated from the operation unit 9 and set such that the object 6 to be cleaned is disposed at a position easy for the user to use.
