Description

Technical Field

[0001] The invention relates to a refrigerator, in particular to a refrigerator equipped with a cleaning machine, and belongs to the field of household appliances. Background Art

[0002] A dishwasher is a device that uses a nozzle to spray high-pressure washing water to clean dishes. Currently, dishwashers are installed and placed separately. Whether they are independent, built-in, drawer-type, or desktop, they all require a specific separate installation location in the kitchen. When the family kitchen has been decorated, the range of models that users can choose is relatively small. At the same time, traditional refrigerators placed in the kitchen are only used to refrigerate and freeze food, and have a single function. As people's requirements for quality of life become higher and higher, people hope that each kitchen appliance has more functions, not only to save space, but also to make life more convenient.

[0003] At present, dishwashers generally use natural drying or fan drying. The drying efficiency of natural drying is relatively low and is limited by many factors. Fan drying is to blow air outwards or blow indoor air into the dishwasher to achieve the effect of auxiliary drying. Although this method can improve the drying efficiency, because the flowing wind is all indoor cold air, to greatly improve the drying efficiency, the power of the drying fan can only be increased, which increases energy consumption and costs. In the existing washing process, after the washing is completed and the drying stage begins, the hot water needs to be heated to a very high temperature to achieve drying by preheating the tableware.

[0004] At present, in order to achieve better washing results, dishwashers generally use hot water to wash dishes, and the washing water is heated by a heater installed in the water inlet pipe to heat the water circulation. Since the power of the heater is relatively large, it occupies most of the power consumption of the washing machine, and also increases the total power consumption of the washing machine.

[0005] In addition, the existing dishwasher heats the washing water before washing and dries the dishes after washing through two systems, which makes the structure of the washing machine complicated, increases the cost and energy consumption. Summary of the invention

[0006] The main technical problem solved by the present invention is to provide a washing machine heating method which can significantly reduce energy consumption while improving the functionality of the refrigerator and the washing machine.

[0007] Another major technical problem solved by the present invention is to provide a cleaning machine with a simple structure, low cost and greatly reduced energy consumption, and at the same time provide a refrigerator equipped with the cleaning machine.

[0008] To achieve the above object, the technical solution of the present invention is:

[0009] A washing machine heating method introduces heat from a refrigerator radiator directly into the washing machine by heat transfer, and is used to heat washing water entering the washing machine before washing and / or to heat tableware after washing to dry the tableware.

[0010] Another technical solution of the present invention is:

[0011] A cleaning machine using the heating method as described above comprises a heat transfer device installed in the cleaning machine for heat transfer, wherein the heat transfer device is made of metal material, one end of the heat transfer device is in direct contact with the radiator, and the other end extends into the cleaning machine.

[0012] Furthermore, the heat transfer device includes a first heat transfer body and a second heat transfer body which are separately arranged, the first heat transfer body is in direct contact with the radiator, the second heat transfer body is in direct contact with the first heat transfer body, and the second heat transfer body extends into the interior of the cleaning machine.

[0013] Furthermore, the first heat transfer body is a sheet-like structure, and the second heat transfer body is a block-like structure.

[0014] Furthermore, the first heat transfer body is connected to a moving device for moving toward the radiator to contact or approach the radiator when heating is required, and moving in the opposite direction to separate from the radiator when heating is not required.

[0015] Furthermore, the shell of the cleaning machine and the wall panels of the refrigerator chamber both have a heat-insulating layer.

[0016] Furthermore, a cold air introduction device is provided on the housing of the cleaning machine for introducing the cold air in the air supply duct of the refrigerator into the interior of the cleaning machine.

[0017] Furthermore, the cold air introduction device includes a cold air inlet opened on the cleaning machine housing and an air inlet opened on the refrigerator chamber wall panel, the air inlet is connected to the refrigeration chamber air supply duct, and a control valve for controlling opening and closing is arranged at the air inlet.

[0018] Another technical solution of the present invention is:

[0019] A refrigerator comprises a box body, wherein a plurality of chambers are provided in the box body, and the above-mentioned cleaning machine is installed in at least one of the chambers.

[0020] Furthermore, the cleaning machine is embedded and fixedly installed in the chamber, or the cleaning machine is installed in the chamber in a pull-out manner.

[0021] In summary, the washing machine heating method, washing machine and refrigerator equipped with the washing machine described in the present invention have the following advantages compared with the prior art:

[0022] (1) The present invention realizes the combination of a refrigerator and a washing machine. The washing machine is installed in a certain layer of the refrigerator's cold storage space and isolated from other cold storage areas. This can realize the function of the washing machine and hide the washing machine in the refrigerator. When not washing, tableware and other items in the refrigerator can be placed, thereby improving the space utilization of the kitchen and refrigerator, and improving the functionality of the refrigerator. It not only saves space, but also makes it more convenient for users to use. Moreover, since the washing machine is installed in the refrigerator, the overall heat preservation and noise reduction can be greatly improved.

[0023] (2) The present invention transfers the heat generated by the refrigerator radiator to the inside of the washing machine through a heat transfer device to heat the washing water or dry the dishes, thereby ensuring the heating effect during the washing process. Not only can the washing and drying effects be guaranteed, but also the energy consumption can be reduced to the greatest extent, thereby achieving the purpose of energy saving and environmental protection.

[0024] (3) The present invention utilizes a heat transfer device to transfer the heat generated by the refrigerator radiator to the interior of the washing machine, and the heat is used to heat the washing water and dry the dishes. The drying of the dishes and the heating of the washing water share a common heating system, which simplifies the structure of the washing machine and can further reduce energy consumption to a certain extent.

[0025] (4) The present invention provides a cold air introduction device on the shell of the dishwasher, which can introduce the cold air in the refrigeration air supply duct of the refrigerator into the interior of the dishwasher. When the dishwasher does not need to work, it can be used as a refrigerator compartment, further improving the functionality of the refrigerator and the dishwasher, and increasing the space utilization rate of the kitchen and the refrigerator.

[0026] (5) The cleaning machine can be installed on any type of refrigerator, such as a single-door refrigerator, a side-by-side refrigerator or a French refrigerator, as needed, and has a wide range of applications without restriction. BRIEF DESCRIPTION OF THE DRAWINGS

[0038] like Figures 1 to 4 As shown, in this embodiment, a refrigerator equipped with a washing machine is provided, and the refrigerator may be a single-door refrigerator, a side-by-side refrigerator, a French refrigerator, etc. The refrigerator includes a box body 1, and a plurality of chambers 2 are provided in the box body 1, and different chambers can be used as a refrigerator or a freezer as needed. A washing machine 3 is installed in one of the chambers 2, or in a part of a chamber 2. The washing machine 3 can be used for washing tableware, various fruits, vegetables or other items.

[0039] like Figure 1 As shown, in this embodiment, a French refrigerator is taken as an example for detailed description.

[0040] The upper part of the refrigerator body 1 is a chamber 2 with a double door, which is used as a refrigerating chamber. The lower part of the box 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 a chamber 2 located in the middle, and the cleaning machine 3 is embedded and fixedly installed in the chamber 2 located in the middle.

[0041] The cleaning machine 3 provided in this embodiment is embedded and fixedly installed inside the chamber 2 located in the middle.

[0042] like Figures 2 to 4As shown, the cleaning machine 3 includes a shell 4, which is a box-shaped structure composed of side panels 4a on both sides, a bottom panel 4b, a back panel 4c, a top panel (not shown in the figure) and a door panel 5 on the front, wherein the side panels 4a, the bottom panel 4b, the back panel 4c and the top panel are an integrated structure.

[0043] Among them, the door panel 5 can be rotatably connected to the side panel 4a, the bottom panel 4b or the top panel, and the door panel 5 can be opened when taking and placing tableware. When the door panel 5 is in a closed state, it is integrated with the box body 1 of the refrigerator and completely covers the front opening of the chamber 2. In this embodiment, in order to facilitate the taking and placing of tableware, the door panel 5 adopts a flip-down structure. The two sides of the bottom of the door panel 5 are respectively connected to the corresponding side panels 4a through a hinge mechanism, and the door panel 5 is flipped up and down under the action of the hinge mechanism. There is a gap between the bottom panel 4b and the bottom wall of the chamber 2. After the door panel 5 is flipped down, its bottom will be inserted into the space below the bottom panel 4b, which is convenient for opening the door panel 5. A hinge shaft 8 is extended outward on both sides of the bottom of the side panel 4a, and a hinge seat 7 is correspondingly extended on both sides of the bottom of the door panel 5. The hinge seat 7 is provided with a mounting hole, and the mounting hole is sleeved on the hinge shaft 8. 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 may be a mechanical locking structure or a magnetic attraction structure, to ensure that when the door panel 5 is closed, the door panel 5 can be stably and tightly sealed with the body 1 and the side panels 4a, the bottom panel 4b, and the top panel.

[0044] The shell 4 of the cleaning machine and the wall panels of the refrigerator chamber 2 are both provided with a heat-insulating layer. Specifically, there is a certain gap between the outer surface of the side panels 4a, bottom panel 4b, back panel 4c, and top panel of the shell 4 and the inner surface of the chamber 2, and a layer of heat-insulating material (not shown in the figure) is filled in the gap. In this embodiment, it is preferred that a layer of heat-insulating material is laid on the inner surface of the chamber 2 and the outer surface or inner surface of the side panels 4a, bottom panel 4b, back panel 4c, and top panel of the cleaning machine. The heat-insulating material can be asphalt or glass wool, etc., or the wall panels around the chamber 2 and the side panels 4a, bottom panel 4b, back panel 4c, and top panel of the cleaning machine are all sandwich structures filled with heat-insulating material in the middle. The inner surface of the door panel 5 is also covered with a layer of heat-insulating material, or the door panel 5 is preferably a sandwich structure filled with heat-insulating material in the middle, so as to avoid the cleaning machine 3 affecting the refrigeration operation of the refrigerator during the heating and washing process, thereby causing the loss of cold and reducing the refrigeration effect.

[0045] A circle of sealing strips (not shown in the figure) are arranged on the outer edges of the side panels 4a, the bottom panel 4b and the top panel. The outer edges of the side panels 4a, the bottom panel 4b, the top panel and the outer surface of the refrigerator body 1 are in the same plane. When the door panel 5 is in the closed state, the sealing strips are used to compress and seal the door panel 5 with the side panels 4a, the bottom panel 4b and the top panel to ensure that the washing water does not leak out during washing.

[0046] A rack 6 for fixing tableware and cooking utensils is installed inside the housing 4. The rack 6 can be slidably installed in the housing 4 through a sliding mechanism to facilitate the rack 6 to be pulled out of the cleaning machine 3. The sliding mechanism includes a plurality of pulleys 25 installed at the bottom of both sides of the rack 6. Two slideways (not shown in the figure) are correspondingly arranged on the bottom plate 4b of the housing 4. The pulley 25 slides in the slideway so that the pulley 25 carries the rack 6 and smoothly enters and exits the housing 4 to achieve the taking and placing of tableware. The pulley 25 also lifts the rack 6 to avoid the spray system 7 at the bottom. In addition to being able to place tableware and cooking utensils, the rack 6 can also be used as a fruit and vegetable washing basket, and fruits and vegetables can be placed on the rack 6 for washing. The rack 6 can also slide out of the housing 4 completely, and a fruit and vegetable washing basket is placed inside the cleaning machine 3 for washing fruits and vegetables.

[0047] A cleaning system is also installed inside the housing 4. The cleaning system may adopt a spray device, an ultrasonic cleaning device (not shown in the figure), or both methods may be used simultaneously.

[0048] The spray device includes one or more spray arms and a water tank assembly 13. In this embodiment, in order to ensure the washing effect, two spray arms are preferably installed in the housing 4, namely, a first spray arm 9 and a second spray arm 10. The first spray arm 9 is arranged on the bottom plate 4b and is a rotatable dynamic spray arm. The second spray arm 10 is installed on the back plate 4c and is a static spray arm. The first spray arm 9 and the second spray arm 10 are connected through a water pipe 16. In addition to the first spray arm 9 and the second spray arm 10, a top spray device can also be provided as needed. The top spray device can be a dynamic spray or a static spray.

[0049] A plurality of spray holes 11 are provided on the first spray arm 9 and the second spray arm 10. Below the first spray arm 9 is a water tank assembly 13. A water inlet 12 and a water outlet are provided on the cleaning machine 3, wherein the water inlet can be provided on the back plate 4c or the side plate 4a as required, or the water inlet can be provided on the water tank assembly 13 at the bottom. Figure 4 As shown, in this embodiment, the water inlet 12 is preferably arranged on the back plate 4c. The water inlet 12 is connected to the water source through a water inlet pipe, and the water inlet pipe needs to pass through the box 1 of the refrigerator. 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 installed as a whole 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 plate 6 at the top, a water tank in the middle, a filter, a washing pump, a drainage pump, etc. The side opening of the sink assembly 13 is connected to the outlet pipe 14, and the outlet pipe 14 passes through the box 1 of the refrigerator and is connected to the sewer. Two openings are opened on the box 1 corresponding to the water inlet pipe and the outlet pipe 14, and sealing members are provided at both openings. The water inlet pipe and the outlet pipe 14 are respectively sealed and connected to the box 1 at the opening through sealing members.

[0050] The washing water enters the housing 4 of the washing machine through the water inlet 12 on the back plate 4c, enters the water tank through the drain plate 6 at the bottom, enters the water cavity of the first spray arm 9 along the water flow channel, and finally sprays out from the spray hole 11 on the first spray arm 9 to wash the tableware placed in the housing 4 waiting to be washed. 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 to the second spray arm 10 through the water pipe 16, and sprayed out from the spray hole 11 on the second spray arm 10 to wash the items to be washed in the housing 4.

[0051] A display panel (not shown) of the cleaning machine 3 can be separately provided on the door panel 5. A receiving cavity is provided on the door panel 5. The electrical components are installed in the receiving cavity. A touch screen is installed on the surface of the receiving cavity to facilitate user operation and observation. The display panel of the cleaning machine 3 can also be integrated with the display panel of the refrigerator, and the display panel of the refrigerator is used to control and display the working status of the cleaning machine 3. For the convenience of operation, a handle 15 is provided on the door panel 5.

[0052] A water softener may be connected in series to the water inlet pipe, and the water from the water source first passes through the water softener before entering the housing 4 for washing. The water softener may be installed in the space between the back plate 4c and the box body 1, or the width of the housing 4 may be reduced to leave a space for installing the water softener on one side of the housing 4. An ozone generator or other device may also be installed in the space. If an ozone generator is installed, an opening is required on the side wall 4a, and a valve is provided at the opening to introduce ozone into the housing 4.

[0053] The present invention combines a cleaning machine with a refrigerator, utilizes part of the space of the refrigerator as a cleaning machine, and isolates the cleaning machine from other refrigeration and freezing areas to form an independent cleaning machine module, so that the refrigerator has the function of refrigerating frozen food, and at the same time has the function of cleaning tableware, fruits and vegetables. When the cleaning machine is not working, the space of the cleaning machine can also be used to store tableware, fruits and vegetables, and other items stored in the refrigerator, without having to take them out and find another space to store them. It is convenient to use, and can improve the space utilization rate of the refrigerator and the kitchen, solves the problem of installing the cleaning machine in the kitchen, and improves the functionality of the refrigerator. At the same time, since the cleaning machine is installed inside the refrigerator, the overall heat preservation, noise reduction, etc. can be improved.

[0054] In order to improve the washing effect, the washing machine will heat the washing water during washing and use the higher temperature washing water for washing. Figure 5As shown, in this embodiment, a heat transfer device is provided between the refrigerator and the washing machine 3, and the heat of the refrigerator radiator 19 is directly introduced into the interior of the washing machine 3 by heat transfer, so as to heat the washing water. The heat transfer device can also be used to transfer the heat to the interior of the washing machine at the end of washing, so as to heat the air inside the washing machine and further heat the tableware to achieve the purpose of drying the tableware. It can achieve a good heating and drying effect, and effectively improve the drying efficiency and heating efficiency of the washing machine, greatly reducing energy consumption. At the same time, it can also ensure that there is always a heating effect during the washing process.

[0055] 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 interior of the cleaning machine 3 .

[0056] The heat transfer device may be an integrated structure. In the present embodiment, the heat transfer device preferably adopts a split structure, including a first heat transfer body 21 and a second heat transfer body 22 which are separately arranged. The first heat transfer body 21 is directly in contact with the radiator 19, and the second heat transfer body 22 is in direct contact with the first heat transfer body 21. The second heat transfer body 22 is embedded and installed on the housing 4 of the washing machine 3, with one side in direct contact with the first heat transfer body 21 and the other side extending into the interior of the washing machine 3. The heat of the radiator 19 is sequentially transferred to the interior of the washing machine through the first heat transfer body 21 and the second heat transfer body 22, and the heat emitted by the second heat transfer body 22 is used to heat the washing water or tableware. Among them, the first heat transfer body 21 is preferably a sheet structure, and the second heat transfer body 22 is preferably a block structure.

[0057] The temperature of the refrigerator radiator 19 is about 50°C. The heat generated by the radiator 19 is transferred to the inside of the washing machine 3 through the first heat transfer body 21 and the second heat transfer body 22. The washing water flows into the washing machine 3 from the water inlet 12 before washing, and accumulates at the bottom of the washing machine in direct contact with the second heat transfer body 22. The second heat transfer body 22 is used to heat the water inside the washing machine, which can ensure the heating effect during the washing process. Alternatively, after washing, the second heat transfer body 22 is used to heat the air inside the washing machine 3, and then heat the tableware inside the washing machine 3 to achieve the purpose of drying the tableware. If the heating does not reach the required temperature, other auxiliary heating devices can be used for auxiliary heating. The auxiliary heating device can be the auxiliary heating device described in the third and fourth embodiments, or it can be a heater installed in the water circuit of the washing machine to minimize energy consumption and achieve the purpose of energy saving and environmental protection.

[0058] In this embodiment, a heat transfer device is used to transfer the heat generated by the refrigerator radiator 19 to the inside of the washing machine 3. This heat can not only be used to heat the washing water, but also can be used to dry the dishes after washing. The drying and heating of the washing water share a common system, which simplifies the structure of the washing machine and can further reduce energy consumption to a certain extent.

[0059] When the washing machine is not working, in order to avoid the first heat transfer body 21 and the second heat transfer body 22 heating the inside of the washing machine 3 for a long time and causing damage to the washing machine. In this embodiment, the first heat transfer body 21 is connected with a moving device, and the moving device 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 gear rack, a lead screw, etc. When heating is required, the first heat transfer body 21 is moved toward the radiator 19, so that the first heat transfer body 21 is close to the radiator 19 or directly contacts 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 temperature of the washing water reaches the requirement, the first heat transfer body 21 can be controlled to move away from the radiator 19.

[0060] Embodiment 2:

[0061] like Figure 6 As shown, the difference from the first embodiment is that in this embodiment, the cleaning machine 3 is a drawer type and can be pulled out of the chamber 2 of the refrigerator as a whole.

[0062] The housing 4 of the cleaning machine 3 is a box-shaped structure composed of side panels 4a, bottom panel 4b, back panel 4c, front panel 4d and top cover (not shown in the figure) on both sides. The size of the front panel 4d can cover the front opening of the refrigerator chamber 2 when it is closed. Among them, the side panels 4a, bottom panel 4b, back panel 4c and front panel 4d are an integrated structure, and the top cover is a movable structure, which can be selectively sealed and connected with the side panels 4a, bottom panel 4b, back panel 4c and 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 outward, the linkage top is lifted, and the top cover does not extend out of the chamber 2. When the drawer-type housing 4 is retracted to the inside of the chamber 2, the top cover linkage action covers the top of the drawer-type housing 4 and realizes a sealed connection. The linkage mechanism of the top cover and the housing 4 can adopt the linkage mechanism used in the drawer-type cleaning machine in the prior art, and the top cover and the drawer can also be controlled by a controller to move synchronously.

[0063] A shelf 6 for fixing tableware, cooking utensils, fruits and vegetables waiting to be washed is installed inside the housing 4. The shelf 6 can be directly placed on the bottom plate 4b of the housing 4. In order to facilitate the placement of tableware, the shelf 6 can also be connected to a lifting device. When the tableware needs to be placed, the shelf 6 is raised by the lifting device to avoid the user bending over, which is convenient for operation. After the placement is completed, the shelf 6 is retracted to the normal position by the lifting device. The shelf 6 can be completely removed, and a fruit and vegetable washing basket is placed inside the washing machine 3 for washing fruits and vegetables.

[0064] Slide rail assemblies 18 are provided between the outer surfaces of the two side plates 4a of the housing 4 and the side walls of the chamber 2 of the refrigerator, and the cleaning machine 3 is pulled out in the horizontal direction through the slide rail assemblies 18. The slide 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 sets of slide rail assemblies 18 are provided.

[0065] In this embodiment, a layer of thermal insulation material is applied on the inner or outer surface of the side panels 4a, bottom panel 4b, back panel 4c, top cover and the inner surface of the front panel 4d of the shell 4. The thermal insulation material can be asphalt or glass wool, etc. At the same time, a layer of thermal insulation material is also applied on the inner surface of the chamber 2. Alternatively, the wall panels around the chamber 2 and the side panels 4a, bottom panel 4b, back panel 4c, front panel 4d and top cover of the cleaning machine 3 all adopt a sandwich structure filled with thermal insulation material in the middle, so as to prevent the cleaning machine 3 from affecting the refrigeration operation of the refrigerator during the heating and washing process, thereby causing cold loss and reducing the refrigeration effect.

[0066] A circle of door sealing strip (not shown in the figure) is also arranged on the inner surface of the front panel 4d. When the cleaning machine 3 is retracted into the interior of the refrigerator chamber 2, the front panel 4d is compressed and sealed with the refrigerator body 1 by the door sealing strip to ensure that the washing water does not leak during washing and the cooling capacity is not lost when the cleaning machine 3 is not working.

[0067] A cleaning system is also installed inside the housing 4. The cleaning system can use a spray device, an ultrasonic cleaning device (not shown in the figure), or both methods are used at the same time. The cleaning system is the same as that described in the first embodiment, except that the water inlet pipe and the water outlet pipe are retractable structures, such as soft bellows, and the parts of the water inlet pipe and the water outlet pipe inside the box 1 can be retracted as the cleaning machine 3 is pulled out.

[0068] like Figure 6 As shown, in this embodiment, a cold air introduction device is also provided on the cleaning machine, which is used to introduce the cold air in the air supply duct of the cold storage room into the interior of the cleaning machine 3, so that when the cleaning machine 3 is not working, the cleaning machine 3 can be used as a cold storage room to refrigerate and store food.

[0069] The cold air introduction device includes a cold air inlet 17 opened on the shell 4 and an air inlet (not shown in the figure) opened on the wall panel of the refrigerator chamber 2. The air inlet is connected to the air supply duct of the refrigerator chamber. A control valve is provided at the air inlet to control the opening and closing of the air inlet, or the air inlet provided on the wall panel of each chamber 2 of the air-cooled refrigerator is retained.

[0070] The cold air inlet 17 is preferably arranged corresponding to the air inlet, such as Figure 6As shown, the cold air inlet 17 is opened on the back plate 4c. The cold air inlet 17 and the air inlet can be connected by a connecting channel, and the cold air in the air supply duct of the refrigerator compartment is directly introduced into the interior of the cleaning machine through the air inlet, the connecting channel and the cold air inlet 17 in sequence. Alternatively, the cold air in the air supply duct of the refrigerator compartment enters the chamber 2 through the air inlet, and then enters the interior of the cleaning machine through the cold air inlet 17. A corresponding cold air return air inlet is opened at the bottom of the bottom plate 4c or the side plate 4a and the back plate 4c of the shell 4, and an openable and closable sealing plate is installed at the cold air return air inlet to ensure that there is no water leakage when the cleaning machine is working. A return air inlet is also set on the wall plate of the chamber 2 to form a cold air circulation inside the cleaning machine.

[0071] When the cleaning machine 3 needs to work, the control valve at the air inlet of the chamber 2 is closed, the air supply duct of the refrigerator compartment is disconnected from the interior 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 control the control valve at the air inlet to open through the operation display panel. At this time, the air supply duct of the refrigerator compartment is connected to the internal space of the cleaning machine 3, and the cold air will enter the interior of the cleaning machine 3. The cleaning machine 3 will be used as a separate cold storage room for storing fruits, vegetables and other foods. This embodiment further improves the space utilization rate of the kitchen and refrigerator. At this time, the first heat transfer body 21 and the second heat transfer body 22 arranged in the chamber 2 and the cleaning machine 3 can assist in conducting the cold to the interior of the cleaning machine, shortening the time for cooling inside the cleaning machine 3.

[0072] The cold air inlet 17 can also be provided on the embedded cleaning machine as described in the first embodiment.

[0073] Embodiment three:

[0074] like Figure 7 As shown, the difference from the above embodiment is that in this embodiment, an auxiliary heating device can be further provided between the refrigerator body 1 and the washing machine 3, which can be used to dry the internal space of the washing machine and the dishes after the last washing, and can also be used to heat the washing water before washing. The auxiliary heating device can be used together with the heat transfer device in the first embodiment, so that the heat of the radiator 19 can be more fully utilized, and the required temperature can be reached in a shorter time. The auxiliary heating device and the heat transfer device in the first embodiment can also be used separately as needed.

[0075] The auxiliary heating device can be installed in an embedded fixed cleaning machine as described in the first embodiment, or can be installed in a drawer-type cleaning machine as described in the second embodiment.

[0076] The auxiliary heating device includes a first opening arranged on the housing 4 of the cleaning machine 3. The position of the first opening is determined according to the installation position of the refrigerator radiator 19. Correspondingly, a second opening is opened on the housing 1 of the refrigerator corresponding to the radiator 19. The size of the second opening is smaller than the area of ​​the side wall of the chamber 2. The heat emitted by the radiator 19 during operation first enters the chamber 2 through the second opening under the action of the fan 20. Because the inner wall of the chamber 2 is heat-insulated, the hot air entering the chamber 2 will not affect the refrigeration operation of the refrigerator. In this embodiment, the radiator 19 of the refrigerator is installed on the side wall of the refrigerator housing 1. Correspondingly, a first opening is arranged on a side panel 4a of the housing 4 of the cleaning machine. A fan 20 is installed at the first opening. The heat generated by the refrigerator radiator 19 is directly introduced into the interior of the cleaning machine 3 under the action of the fan 20. In order to form a hot air circulation, an exhaust port is also arranged on the housing 4 of the cleaning machine 3 and the housing 1 of the refrigerator.

[0077] In the case where the cleaning machine 3 is provided with a cold air inlet 17, it is necessary to install an openable and closable heat-insulating baffle (not shown in the figure) at the second opening. When the cleaning machine is working, the heat-insulating baffle is opened, and the cold air inlet 17 provided on the cleaning machine housing 4 can assist in introducing the hot air entering the chamber 2 into the interior of the cleaning machine 3. When the cleaning machine is not working and is used as a cold storage room, the second opening is closed by the heat-insulating baffle to prevent the heat of the radiator 19 from entering the chamber 2. Of course, the cold air inlet 17 for introducing cold air and the first opening for quoting hot air can also be combined into one, and a fan is also installed. When the cleaning machine 3 is working, the hot air entering the chamber 2 is introduced by the opening, and when the cleaning machine is not working, the cold air entering the chamber 2 can be quoted by the opening.

[0078] Embodiment 4:

[0079] like Figure 8 As shown, the difference from the third embodiment is that, in this embodiment, an air duct 23 extends from the first opening on the cleaning machine housing 4 to the inside of the cleaning machine 3, and the air duct 23 is tilted downward as a whole and opens toward the bottom plate 4b.

[0080] During washing, water from the water source enters the housing 4 through the water inlet 12. After the water enters, the fan 20 is started to blow hot air at about 50°C into the interior of the cleaning machine 3 along the air duct 23, directly blowing hot air to the cold water at the bottom of the cleaning machine 3 for heating.

[0081] As described above, similar technical solutions can be derived from the scheme contents given in the accompanying drawings. However, any simple modification, equivalent changes and modifications made to the above embodiments according to the technical essence of the present invention without departing from the contents of the technical scheme of the present invention still fall within the scope of the technical scheme of the present invention.
