For easy operation, a handle 15 is provided on the front panel 4d.

[0050] 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 cleaning machine housing 4 may be reduced and the water softener may be installed in a space on one side of the housing 4. Devices such as an odor generator may also be installed in the space. If an ozone generator is installed, an opening is required on the side wall 4a of the cleaning machine 3, and a valve is provided at the opening to introduce ozone into the cleaning machine 3.

[0051] 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.

[0052] Embodiment 2:

[0053] like Figure 4 and Figure 5 As shown, the difference between this embodiment and the first embodiment is that the shell 4 in this embodiment is integrally embedded and installed in the chamber 2 .

[0054] The cleaning machine 3 includes a housing 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 front panel 4d. The side panels 4a, the bottom panel 4b, the back panel 4c and the top panel are an integrated structure. The front panel 4d is a door panel of the cleaning machine and is connected to the housing 4 in an openable manner. The front panel 4d can be opened when taking and placing tableware. When the front panel 4d is closed, it is integrated with the box body 1 of the refrigerator and completely covers the front opening of the chamber 2.

[0055] In this embodiment, in order to facilitate the taking and placing of tableware, the front panel 4d adopts a flip-down structure. The two sides of the bottom of the front panel 4d are respectively connected to the corresponding side panels 4a through a hinge mechanism, and the front panel 4d can be flipped up and down under the action of the hinge mechanism. A hinge shaft 24 is extended outward from each of the two sides of the bottom of the side panel 4a, and a hinge seat 7 is extended and arranged on the two sides of the bottom of the front panel 4d. The hinge seat 7 is provided with a mounting hole, and the mounting hole is mounted on the hinge shaft 24. The front panel 4d rotates upward or downward around the hinge shaft 24. There is a gap between the bottom plate 4b and the bottom wall of the chamber 2. After the front panel 4d is flipped down, its bottom will be inserted into the space below the bottom plate 4b, which is convenient for opening the front panel 4d. A locking mechanism is provided between the front panel 4d 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 front panel 4d is closed, the front panel 4d can be stably and tightly sealed with the body 1 and the side panels 4a, the bottom panel 4b and the top panel.

[0056] 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 front panel 4d is also covered with a layer of heat-insulating material, or the front panel 4d 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.

[0057] 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 front panel 4d is in the closed state, the sealing strips are used to compress and seal the front panel 4d 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.

[0058] 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 out during washing and the cooling capacity is not lost when the cleaning machine 3 is not working.

[0059] A shelf 5 for fixing tableware, cooking utensils, fruits and vegetables waiting to be washed is installed inside the housing 4. The shelf 5 can be slidably installed in the housing 4 through a sliding mechanism to facilitate the shelf 5 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 shelf 5. 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 shelf 5 in and out of the housing 4 smoothly to realize the taking and placing of tableware. The shelf 5 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.

[0060] Embodiment three:

[0061] In order to improve the washing effect, the washing machine will heat the washing water when washing, especially when washing dishes, and use the washing water with higher temperature for washing. Figure 6As shown, in this embodiment, a heat introduction 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 introduction device can also be used to transfer the heat to the interior of the washing machine 3 at the end of washing, so as to heat the air inside the washing machine 3 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.

[0062] The heat introduction device in this embodiment is made of a metal material with good thermal conductivity. One end of the heat introduction device is in direct contact with the radiator 19 , and the other end extends into the interior of the cleaning machine 3 .

[0063] The heat introduction device can be an integrated structure. In this embodiment, the heat introduction 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 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, one side of which is in direct contact with the first heat transfer body 21, and the other side extends into the interior of the washing machine 3. The heat of the radiator 19 is transferred to the interior of the washing machine 3 through the first heat transfer body 21 and the second heat transfer body 22 in turn, and the washing water or tableware is heated by the heat emitted by the second heat transfer body 22. 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.

[0064] 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 to heat the water inside the washing machine 3. It can ensure that the heating effect is achieved during the washing process. Alternatively, after washing, the dishes inside the washing machine 3 are directly heated to achieve the purpose of drying. 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 a heater installed in the water path of the washing machine to minimize energy consumption and achieve the purpose of energy saving and environmental protection.

[0065] In this embodiment, the heat generated by the refrigerator radiator 19 is transferred to the inside of the washing machine 3 by a heat introduction device. 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.

[0066] When the cleaning machine 3 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 cleaning machine 3 for a long time and causing damage to the cleaning machine 3. 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.

[0067] Embodiment 4:

[0068] like Figure 7 As shown, the difference from the above-mentioned embodiment 2 is that in this embodiment, the heat introduction device arranged between the refrigerator body 1 and the cleaning machine 3 includes a first opening arranged on the cleaning machine housing 4, and 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 refrigerator body 1 corresponding to the radiator 19, and 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 refrigerator radiator 19 is installed on the side wall of the refrigerator body 1, and a first opening is correspondingly arranged on a side side plate 4a of the cleaning machine housing 4, and 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 refrigerator body 1.

[0069] When the last wash is finished and the drying process begins, the fan 20 is started to blow hot air at about 50°C into the interior of the washing machine 3 to heat the dishes and achieve the purpose of drying the dishes. During the last wash process, the washing water does not need to be heated to a very high temperature, or does not need to be heated. Only the hot air blown in can achieve a good drying effect. The heat introduced by the fan 20 can also be used to heat the washing water before washing 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 can be started. Only the hot air blown in can achieve a good heating effect, effectively improving the heating efficiency of the washing machine and reducing energy consumption.

[0070] The heat introduction device can be used together with the heat introduction device in the third 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 heat introduction device and the heat introduction device in the third embodiment can also be used separately as needed.

[0071] In the case where a cold air inlet is provided on the cleaning machine 3 as described in the fifth embodiment, an openable and closable heat preservation baffle (not shown in the figure) needs to be installed at the second opening. When the cleaning machine needs to be heated during operation, the heat preservation baffle is opened, and the cold air inlet 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 3 is not in operation and is used as a cold storage room, the second opening is closed by the heat preservation baffle to prevent the heat of the radiator 19 from entering the chamber 2. Of course, the cold air inlet for introducing cold air and the first opening for introducing hot air can also be combined into one, and a fan is also installed. When the cleaning machine 3 needs to be heated during operation, the hot air entering the chamber 2 is introduced by the opening, and when the cleaning machine 3 is not in operation, the cold air entering the chamber 2 can be introduced by the opening.

[0072] Embodiment five:

[0073] like Figure 8 As shown, the difference from the third embodiment is that, in this embodiment, an air duct 18 extends from the first opening on the cleaning machine housing 4 to the inside of the cleaning machine 3, and the air duct 18 is tilted downward as a whole and opens toward the bottom plate 4b.

[0074] 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 18, directly blowing hot air to the cold water at the bottom of the cleaning machine 3 for heating.

[0075] Embodiment six:

[0076] like Fig. 9 As shown, the difference from the above embodiment is that, in this embodiment, a cold air introduction device can also be provided on the cleaning machine 3, 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.

[0077] 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.

[0078] The cold air inlet 17 is preferably arranged corresponding to the air inlet, and 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 refrigerating chamber is directly introduced into the inside of the cleaning machine 3 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 refrigerating chamber first enters the chamber 2 through the air inlet, and then enters the inside of the cleaning machine 3 through the cold air inlet 17. A corresponding cold air return port 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 port to ensure that there is no water leakage when the cleaning machine 3 is working. A return air port is also set on the wall plate of the chamber 2 to form a cold air circulation inside the cleaning machine 3.

[0079] 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 refrigerating chamber is disconnected from the chamber 2 and the interior of 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 refrigerating chamber is connected with the internal space of the cleaning machine 3, and the cold air enters the chamber 2 through the air inlet, and then enters the interior of the cleaning machine 3 through the cold air inlet 17. The cleaning machine 3 will be used as a separate cold storage room for storing fruits, vegetables and other foods.

[0080] 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.
