Technical Field

[0001] The present invention relates to a refrigerator, and particularly to a refrigerator equipped with a cleaning machine, belonging to the field of household appliances. Background Art

[0002] Whether it is a dishwasher for cleaning tableware or a fruit and vegetable cleaning machine for cleaning fruits and vegetables, they are all devices that use nozzles to spray high-pressure washing water to clean tableware and fruits and vegetables. Currently, dishwashers and fruit and vegetable cleaning machines are installed and placed separately. Whether they are freestanding, built-in, drawer-type, tabletop-type, etc., they all require specific separate installation locations in the kitchen. In the case where the home kitchen has been renovated, the range of models that users can choose from is relatively small. At the same time, traditional refrigerators placed in the kitchen are only used for refrigerating and freezing food, with a single function. As people's requirements for the quality of life are getting higher and higher, people hope that each kitchen appliance has more functions, not only saving space but also making life more convenient. Summary of the Invention

[0003] The main technical problem to be solved by the present invention is to provide a cleaning machine that can be used as a refrigerating chamber when the cleaning machine is not working, further improving the functionality of the refrigerator and the cleaning machine. At the same time, a refrigerator equipped with this cleaning machine is provided.

[0004] To achieve the above object, the technical solution of the present invention is:

[0005] A cleaning machine is provided with a cold air introducing device for introducing cold air in the air supply duct of the refrigerator into the interior of the cleaning machine.

[0006] Further, the cold air introducing device includes a cold air inlet opened on the housing of the cleaning machine and an air inlet opened on the wall panel of the refrigerator chamber. The air inlet is communicated with the air supply duct of the refrigerating chamber, and a control valve for controlling opening and closing is provided at the air inlet.

[0007] Further, a connecting channel is provided between the cold air inlet and the air inlet of the chamber.

[0008] Further, both the housing of the cleaning machine and the wall panel of the refrigerator chamber are provided with heat insulation layers.

[0009] Further, a heat dissipation port is opened on the refrigerator body corresponding to the radiator. The heat dissipation port introduces the heat of the radiator into the chamber, and the cold air inlet introduces the heat into the interior of the cleaning machine.

[0010] Further, the cleaning machine is fixedly installed in the chamber in an embedded manner. A shelf for placing items to be washed is installed in the cleaning machine, and the door panel is installed on the housing of the cleaning machine in an openable manner. When the door panel is in the closed state, it serves as the refrigerator door body to cover the front opening of the chamber.

[0011] Further, the dishwasher can be installed in the chamber in a pull-out manner. A shelf for placing articles to be washed is installed in the dishwasher. When the front panel of the housing is in the closed state, it serves as the refrigerator door body to cover the front opening of the chamber.

[0012] Further, a cleaning system is installed in the dishwasher. The dishwasher is connected with a water inlet pipe and a water outlet pipe. The water inlet pipe passes through the refrigerator body and is connected to a water source or connected to the water inlet pipe of an ice maker, and the water outlet pipe passes through the refrigerator body and is connected to a sewer.

[0013] Further, the cleaning system is a spraying device and / or an ultrasonic cleaning device.

[0014] Another technical solution of the present invention is:

[0015] A refrigerator includes a refrigerator body, and there are multiple chambers in the refrigerator body. The above-mentioned dishwasher is installed in at least one of the chambers.

[0016] In summary, compared with the prior art, the dishwasher and the refrigerator equipped with the dishwasher of the present invention have the following advantages:

Detailed implementation manners

[0030] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific implementation manners:

[0031] Embodiment 1:

[0032] As Figures 1 to 3 shown, in this embodiment, a refrigerator equipped with a cleaning machine is provided. The refrigerator can be a single-door refrigerator, a double-door refrigerator, a French refrigerator, etc. The refrigerator includes a box body 1, and there are multiple chambers 2 in the box body 1. Different chambers can be used as a refrigerating chamber or a freezing chamber according to needs. A cleaning machine 3 is installed in one of the chambers 2 or a part of the space in one chamber 2. The cleaning machine 3 can be used for cleaning tableware, various fruits, vegetables or other items.

[0033] As Figure 1As shown, in this embodiment, a French refrigerator is taken as an example for detailed description.

[0034] The upper half of the refrigerator body 1 has a chamber 2 with double doors, and this chamber 2 is used as a refrigerating chamber. The lower half of the body 1 has three chambers 2, and the two drawer-type chambers 2 at the bottom are used as freezing chambers. In this embodiment, a cleaning machine 3 is placed in the middle chamber 2, and the cleaning machine 3 is fixedly installed by embedding inside the middle chamber 2.

[0035] As Figure 2 and Figure 3 shown, the cleaning machine 3 provided in this embodiment is of a drawer type and can be pulled out of the chamber 2 of the refrigerator as a whole.

[0036] The housing 4 of the cleaning machine 3 is a box-shaped structure composed of side plates 4a on both sides, a bottom plate 4b, a back plate 4c, a front panel 4d on the front, and a top cover (not shown in the figure). The size of the front panel 4d can cover the front opening of the refrigerator chamber 2 in the closed state. Among them, the side plates 4a, the bottom plate 4b, the back plate 4c, and the front panel 4d are of an integral structure, and the top cover is a movable structure and can be selectively sealed and connected to the side plates 4a, the bottom plate 4b, the back plate 4c, and the front panel 4d. The top cover is connected to the drawer-type housing 4 through a linkage mechanism, and the linkage between the top cover and the drawer-type housing 4 is realized through the linkage mechanism, that is, when the drawer-type housing 4 is pulled outwards, the linkage top cover is lifted, and the top cover does not extend out of the chamber 2. When the drawer-type housing 4 retracts into the chamber 2, the top cover makes a linkage movement to cover above the drawer-type housing 4 and realizes a sealed connection. The linkage mechanism between the top cover and the housing 4 can adopt the linkage mechanism used in the drawer-type cleaning machine in the prior art, or the controller can be used to control the top cover and the drawer to move synchronously.

[0037] A shelf 6 for fixing tableware, cooking utensils, fruits and vegetables and other items to be washed is installed inside the housing 4, and the shelf 6 can be directly placed on the bottom plate 4b of the housing 4. For the convenience of taking and placing tableware, the shelf 6 can also be connected to a lifting device. When it is necessary to take and place tableware, the lifting device is used to raise the shelf 6 to avoid the user bending down, which is convenient for operation. After the taking and placing is completed, the lifting device is used to retract the shelf 6 to the normal position. The shelf 6 can be taken out completely, and a fruit and vegetable cleaning basket is placed inside the cleaning machine 3 for cleaning fruits and vegetables.

[0038] Sliding rail assemblies 18 are respectively arranged between the outer surfaces of the two side plates 4a of the housing 4 and the side walls of the refrigerator chamber 2, and the cleaning machine 3 is pulled horizontally through the sliding rail assemblies 18. The sliding rail assemblies 18 can also be installed between the lower surface of the bottom plate 4b of the housing 4 and the bottom wall of the chamber 2, and two groups of sliding rail assemblies 18 are provided.

[0039] In this embodiment, a layer of thermal insulation material is laid on the inner or outer surface of the side plate 4a, bottom plate 4b, back plate 4c, top cover of the housing 4, and the inner surface of the front panel 4d. The thermal insulation material can be selected from asphalt, glass wool, etc. At the same time, a layer of thermal insulation material is also laid on the inner surface of the chamber 2. Alternatively, the wall panels around the chamber 2 and the side plate 4a, bottom plate 4b, back plate 4c, front panel 4d, and top cover of the washing machine 3 all adopt a sandwich structure with thermal insulation material filled in the middle, so as to avoid the influence of the washing machine 3 on the refrigeration operation of the refrigerator during the heating and washing process, resulting in cold loss and reducing the refrigeration effect.

[0040] A door sealing strip (not shown in the figure) is also provided on the inner surface of the front panel 4d. When the washing machine 3 retracts into the interior of the refrigerator chamber 2, the front panel 4d uses the door sealing strip to achieve a tight seal with the refrigerator body 1, ensuring that the washing water does not leak out during washing, and no cold loss occurs when the washing machine 3 is not working.

[0041] A cleaning system is also installed inside the housing 4. The cleaning system can adopt a spraying device, an ultrasonic cleaning device (not shown in the figure), or both methods can be used simultaneously.

[0042] Among them, the spraying device includes one or more spraying arms and a water tank assembly 13. In this embodiment, in order to ensure the washing effect, it is preferably to install two spraying arms in the housing 4, namely the first spraying arm 9 and the second spraying arm 10. Among them, the first spraying arm 9 is arranged on the bottom plate 4b and is a rotatable moving spraying arm, and the second spraying arm 10 is installed on the back plate 4c and is a static spraying arm. The first spraying arm 9 and the second spraying arm 10 are connected through a water pipeline 16. In addition to the first spraying arm 9 and the second spraying arm 10, a top spraying device can also be set as needed. The top spraying device can be a moving spraying or a static spraying.

[0043] A plurality of spraying holes 11 are provided on both the first spraying arm 9 and the second spraying arm 10. Below the first spraying arm 9 is the water tank assembly 13. An inlet 12 and an outlet are provided on the washing machine 3. Among them, the inlet can be set on the back plate 4c or the side plate 4a according to needs, or the inlet can be set on the bottom water tank assembly 13. For example Figure 4As shown, in this embodiment, the water inlet 12 is preferably provided on the back panel 4c. The water inlet 12 is connected to a water source through a water inlet pipe, and the water inlet pipe needs to pass through the refrigerator cabinet 1. For a refrigerator with an ice maker, the water inlet pipe can also be directly connected to the water inlet pipe of the ice maker. The sink assembly 13 is integrally installed below the bottom plate 4b, between the bottom plate 4b and the bottom wall of the chamber 2. The sink assembly 13 includes a drain board 6 at the top, a sink in the middle, a filter, a washing pump, a drainage pump, etc. A side opening of the sink assembly 13 leads out a water outlet pipe 14, and the water outlet pipe 14 passes through the refrigerator cabinet 1 and is connected to a sewer. Two openings are provided on the cabinet 1 corresponding to the water inlet pipe and the water outlet pipe 14, and seals are provided at the two openings. The water inlet pipe and the water outlet pipe 14 are respectively hermetically connected to the cabinet 1 at the openings through the seals.

[0044] The washing water enters the housing 4 of the dishwasher through the water inlet 12 on the back panel 4c, enters the sink through the drain board 6 at the bottom, then enters the water chamber of the first spray arm 9 along the water flow channel, and finally sprays out from the spray holes 11 on the first spray arm 9 to wash the tableware or items to be washed placed in the housing 4. Under the thrust of the water flow, the first spray arm 9 rotates around the spray seat. At the same time, the washing water is sent into the second spray arm 10 through a water pipeline 16 and sprays out from the spray holes 11 on the second spray arm 10 to wash the items to be washed in the housing 4.

[0045] A display panel of the dishwasher 3 (not shown in the figure) can be separately provided on the front panel 4d. A receiving cavity is provided on the front panel 4d, and electrical components are installed in the receiving cavity. A touch screen is installed on the surface of the receiving cavity for the convenience of user operation and observation. The display panel of the dishwasher 3 can also be integrated with the display panel of the refrigerator to control and display the working state of the dishwasher 3 by using the display panel of the refrigerator. For the convenience of operation, a handle 15 is provided on the front panel 4d.

[0046] A water softener can also be connected in series on the water inlet pipe. The water from the water source first passes through the water softener and then enters the housing 4 for washing. The water softener can be installed in the space between the back panel 4c and the cabinet 1, or the width of the dishwasher housing 4 can be reduced, and the water softener can be installed in the space on one side of the housing 4. Other devices such as an ozone generator can also be installed in this space. If an ozone generator is installed, an opening needs to be made on the side wall 4a of the dishwasher 3, and a valve is provided at the opening to introduce ozone into the interior of the dishwasher 3.

[0047] The present invention combines a dishwasher with a refrigerator, uses part of the space of the refrigerator as a dishwasher, and isolates the dishwasher from other refrigerating and freezing areas to form an independent dishwasher module, so that the refrigerator has the function of refrigerating and freezing food, and at the same time has the function of washing tableware and fruits and vegetables. When the dishwasher is not working, the space of the dishwasher can also be used to store tableware, fruits and vegetables, and other items stored in the refrigerator, etc., without taking them out and finding another space for storage. It is convenient to use, can improve the space utilization rate of the refrigerator and the kitchen, solves the installation problem of the dishwasher in the kitchen, and improves the functionality of the refrigerator. At the same time, since the dishwasher is installed inside the refrigerator, better improvements can be achieved in terms of overall heat preservation and noise reduction.

[0048] As Figure 2 shown, in this embodiment, a cold air introduction device is further provided on the dishwasher for introducing the cold air in the cold air supply duct of the refrigerating chamber into the interior of the dishwasher 3, so that when the dishwasher 3 is not working, the dishwasher 3 can be used as a refrigerating chamber to refrigerate and store food, etc., further improving the functionality of the refrigerator and the dishwasher and the space utilization rate of the kitchen and the refrigerator.

[0049] The cold air introduction device includes a cold air inlet 17 opened on the housing 4 and an air inlet (not shown in the figure) opened on the wall panel of the refrigerator chamber 2. The air inlet is communicated with the cold air supply duct of the refrigerating chamber. A control valve is provided at the air inlet to control the opening and closing of the air inlet, or the air inlets provided on the wall panel of each chamber 2 of the air-cooled refrigerator are retained. The cold air inlet 17 can also be opened on the built-in dishwasher as described in Embodiment 6.

[0050] The cold air inlet 17 is preferably arranged corresponding to the air inlet on the wall panel of the chamber 2. As Figure 2 shown, the cold air inlet 17 is opened on the back panel 4c. The cold air in the cold air supply duct of the refrigerating chamber enters the chamber 2 through the air inlet and then enters the interior of the dishwasher through the cold air inlet 17. Or, a connection channel can be provided between the cold air inlet 17 and the air inlet to directly introduce the cold air in the cold air supply duct of the refrigerating chamber into the interior of the dishwasher 3 through the air inlet, the connection channel and the cold air inlet 17 in sequence.

[0051] Corresponding cold air return vents are opened on the bottom plate 4c or the side plate 4a and the bottom of the back plate 4c of the housing 4, and an openable and closable sealing plate is installed at the cold air return vents to ensure that there is no water leakage when the dishwasher is working. Air return vents are also provided on the wall panel of the chamber 2 to form a cold air circulation inside the dishwasher.

[0052] When the cleaning machine 3 needs to work, close the control valve at the air inlet of the chamber 2, disconnect the cold air supply duct of the refrigerating chamber from the inside of the chamber 2 and the cleaning machine 3, and the cleaning machine performs normal heating, washing and drying. When the cleaning machine 3 is not working, the user can operate the display panel to control the opening of the control valve at the air inlet. At this time, the cold air supply duct of the refrigerating chamber is communicated with the internal space of the cleaning machine 3, cold air enters the chamber 2, and then enters the inside of the cleaning machine 3 through the cold air inlet 17. The cleaning machine 3 will be used as a refrigerating chamber alone to store foods such as fruits and vegetables. This embodiment further improves the space utilization rate of the kitchen and the refrigerator.

[0053] Embodiment 2:

[0054] The difference from Embodiment 1 is that in order to improve the washing effect, the cleaning machine heats the washing water during washing and uses the relatively hot washing water for washing. In this embodiment, the heat of the refrigerator radiator 19 is blown into the inside of the cleaning machine 3. The temperature of the refrigerator radiator 19 is about 50 °C, which is used to heat the washing water entering the cleaning machine 3 before washing, and can also be used to heat the tableware after washing to achieve drying of the tableware. It can achieve good heating and drying effects, effectively improve the drying efficiency and heating efficiency of the cleaning machine, and greatly reduce energy consumption. At the same time, it can also ensure that there is always a heating effect during the washing process.

[0055] In this embodiment, a heat dissipation opening (not shown in the figure) is provided on the refrigerator body 1 corresponding to the radiator, and the heat dissipation opening introduces the heat of the radiator 19 into the chamber 2. The size of the heat dissipation opening is smaller than the area of the side wall of the chamber 2. A heat preservation baffle is installed at the heat dissipation opening. When the cleaning machine is not working and used as a refrigerating chamber, the heat preservation baffle closes the heat dissipation opening to prevent the heat of the radiator 19 from entering the chamber 2. In order to improve the effect of introducing heat and cold air, a fan 20 can be installed at the cold air inlet 17.

[0056] When the cleaning machine is working, the air inlet communicated with the air supply duct is in a closed state, the heat preservation baffle is opened, the fan 20 is started, the heat dissipation opening introduces the heat of the radiator 19 into the chamber 2, and the hot air entering the chamber 2 enters the inside of the cleaning machine 3 through the cold air inlet 17 under the action of the fan 20. Before washing, the washing water entering the inside of the cleaning machine 3 from the water inlet 12 is heated by the introduced heat of the radiator 19 to improve the washing effect. The water temperature and heating time are controlled by a temperature controller. After the temperature is heated to the required temperature, washing starts. After washing, the tableware in the cleaning machine 3 is heated by the introduced heat of the radiator 19 to achieve the purpose of drying the tableware. Just using the blown hot air can achieve a good heating effect, effectively improve the heating efficiency of the cleaning machine, and reduce energy consumption. In order to form a hot air circulation, an air outlet is also provided on the refrigerator body 1.

[0057] In this embodiment, the cold air inlet 17 is used to transfer the heat generated by the refrigerator radiator 19 to the inside of the dishwasher 3. This not only can utilize this heat to heat the washing water, but also can use this heat to dry the tableware after washing. The drying and the heating of the washing water share a set of systems, which simplifies the structure of the dishwasher and can also further reduce energy consumption to a certain extent.

[0058] Embodiment Three:

[0059] As Figure 4 shown, the difference from Embodiment One and Embodiment Two is that in this embodiment, a first opening is additionally formed on the dishwasher housing 4. The first opening corresponds to the radiator 19, and the fan 20 is installed at the first opening. The first opening is mainly used to introduce the heat of the radiator 19 into the inside of the dishwasher 3, and can assist in introducing cold air into the inside of the dishwasher 3 when the dishwasher 3 is used as a refrigerator compartment.

[0060] Embodiment Four:

[0061] As Figure 5 shown, the difference from Embodiment Three is that in this embodiment, a duct 23 extends from the first opening on the dishwasher housing 4 into the inside of the dishwasher 3. The duct 23 is inclined downward as a whole and opens in the direction of the bottom plate 4b.

[0062] During washing, the water from the water source enters the housing 4 through the water inlet 12. After the water enters, the fan 20 is started, and the hot air at about 50 °C is blown into the inside of the dishwasher 3 along the duct 23, directly blowing hot air against the cold water at the bottom of the dishwasher 3 for heating.

[0063] Embodiment Five:

[0064] As Figure 6 shown, the difference from the above embodiments is that in this embodiment, a heat transfer device can also be installed between the refrigerator and the dishwasher 3 to directly introduce the heat of the refrigerator radiator 19 into the inside of the dishwasher 3 by means of heat transfer. The heat transfer device is made of a metal material with good thermal conductivity. One end of the heat transfer device is in direct contact with the radiator 19, and the other end extends into the inside of the dishwasher 3.

[0065] The heat transfer device can be of an integral structure. In this embodiment, the heat transfer device preferably adopts a split structure, including a first heat transfer body 21 and a second heat transfer body 22 that are separately arranged. The first heat transfer body 21 is directly in contact and connected with the radiator 19, and the second heat transfer body 22 is directly in contact with the first heat transfer body 21. The second heat transfer body 22 is embedded and installed on the housing 4 of the dishwasher 3, in direct contact with the first heat transfer body 21 on one side and extending into the interior of the dishwasher 3 on the other side. The heat of the radiator 19 is sequentially transferred to the interior of the dishwasher through the first heat transfer body 21 and the second heat transfer body 22, and the heat dissipated by the second heat transfer body 22 is used to heat the washing water or tableware. Among them, the first heat transfer body 21 preferably adopts a sheet structure, and the second heat transfer body 22 preferably adopts a block structure.

[0066] The temperature of the refrigerator radiator 19 is about 50 °C. The heat generated by the radiator 19 is transferred to the interior of the dishwasher 3 through the first heat transfer body 21 and the second heat transfer body 22 to heat the water inside the dishwasher 3. It can ensure the heating effect during the washing process. Or, after the washing is completed, the tableware inside the dishwasher 3 is directly heated to achieve the purpose of drying. If the heating fails to reach the required temperature, other auxiliary heating devices can be used for auxiliary heating. The auxiliary heating device can be a heater installed in the water path of the dishwasher to minimize energy consumption to achieve the purpose of energy conservation and environmental protection.

[0067] In this embodiment, using the heat conduction device to transfer the heat generated by the refrigerator radiator 19 to the interior of the dishwasher 3 can not only use this heat to heat the washing water, but also use this heat to dry the tableware after washing. The drying and the heating of the washing water share a set of systems, which simplifies the structure of the dishwasher and can also further reduce energy consumption to a certain extent.

[0068] When the dishwasher 3 is not working, to avoid the first heat transfer body 21 and the second heat transfer body 22 continuously heating the interior of the dishwasher 3 and causing damage to the dishwasher 3. In this embodiment, the first heat transfer body 21 is connected with a moving device, which can be a small transmission mechanism for adjusting the position of the first heat transfer body 21. The moving device includes a small motor and a slide rail. The output shaft of the motor drives the transmission mechanism, and the transmission mechanism drives the first heat transfer body 21 to slide along the slide rail. The transmission mechanism can be a conveyor belt, a rack and pinion, a lead screw, etc.

[0069] When heating is required, the first heat transfer body 21 is moved towards the radiator 19 so that the first heat transfer body 21 approaches the radiator 19 or is in direct contact with the radiator 19. When heating is not required, the first heat transfer body 21 is separated from the radiator 19 by the reverse operation of the motor. The first heat transfer body 21 can also be controlled by a temperature controller. When the heating temperature reaches the required value, the first heat transfer body 21 is controlled to move away from the radiator 19. When the dishwasher is not working and is used as a refrigerator compartment, the first heat transfer body 21 is controlled to be separated from the radiator 19. At this time, the cold quantity entering the chamber 2 can be transferred to the inside of the dishwasher 3 by using the heat conduction performance of the first heat transfer body 21 and the second heat transfer body 22, shortening the time for the inside of the dishwasher 3 to cool down.

[0070] Embodiment Six:

[0071] As Figure 7 and Figure 8 shown, the difference from the above embodiment is that the dishwasher 3 in this embodiment is integrally embedded and fixedly installed in the chamber 2 of the refrigerator. The dishwasher 3 includes a housing 4, and the housing 4 is a box-shaped structure composed of side plates 4a on both sides, a bottom plate 4b, a back plate 4c, a top plate (not shown in the figure), and a door panel 5 on the front. Among them, the side plates 4a, the bottom plate 4b, the back plate 4c, and the top plate are of an integral structure.

[0072] Among them, the door panel 5 is rotatably connected to the side plate 4a, the bottom plate 4b, or the top plate, and the door panel 5 can be opened when taking and placing tableware. When the door panel 5 is in the closed state, it is integrated with the refrigerator body 1, covering all the front openings of the chamber 2. In this embodiment, in order to facilitate taking and placing tableware, the door panel 5 adopts a downward-flipping structure. Both sides of the bottom of the door panel 5 are respectively connected to the corresponding side plates 4a through hinge mechanisms, and the door panel 5 realizes upward and downward flipping under the action of the hinge mechanisms. There is a gap between the bottom plate 4b and the bottom wall of the chamber 2, and the bottom of the door panel 5 will insert into the space below the bottom plate 4b after being flipped downward, facilitating the opening of the door panel 5. A hinge shaft 8 extends outward from both sides of the bottom of the side plate 4a, and a hinge seat 7 is correspondingly provided on both sides of the bottom of the door panel 5. An installation hole is provided on the hinge seat 7, and the installation hole is sleeved on the hinge shaft 8, and the door panel 5 rotates upward or downward around the hinge shaft 8. A locking mechanism is provided between the door panel 5 and the refrigerator body 1 above the chamber 2, which can be a mechanical lock structure or a magnetic attraction structure, ensuring that when the door panel 5 is closed, the door panel 5 can be stably and tightly sealed with the body 1, the side plates 4a, the bottom plate 4b, and the top plate.

[0073] Both the housing 4 of the dishwasher and the wall panel of the refrigerator compartment 2 are provided with heat insulation layers. Specifically, there is a certain gap between the outer surfaces of the side panel 4a, bottom panel 4b, rear panel 4c, and top panel of the housing 4 and the inner surface of the compartment 2, and a layer of heat insulation material (not shown in the figure) is filled in this gap. In this embodiment, it is preferably to lay a layer of heat insulation material on the inner surface of the compartment 2 and the outer or inner surfaces of the side panel 4a, bottom panel 4b, rear panel 4c, and top panel of the dishwasher.
