DETAILED DESCRIPTION

[0033] The typical embodiments embodying the features and advantages of the present application are described in detail in the following description. It should be understood that the present application can be embodied in many different forms and should not be construed as limited to the embodiments set forth herein, and that the description and drawings are to be regarded as illustrative in nature and not as restrictive.

[0034] At present, the cleaning function of the refrigerator is mainly to remove the peculiar smell of the refrigerator by sterilizing gas, and to sterilize the inside of the refrigerator, for example, ozone generator and ultraviolet sterilization lamp. However, because the refrigerator usually has multiple layers of storage shelves for storing goods. The shelf can be a shelf, a drawer, etc., so the shelf will be in direct contact with the goods and is prone to contamination. The shelves of the refrigerator often need to be cleaned regularly to ensure the cleanliness of the refrigerator. Therefore, compared with the traditional refrigerator, it is urgent to provide a refrigerator with cleaning function.

[0035] For the cleaning of the refrigerator, some conventional refrigerators use a spraying device to clean the entire refrigerator in a way similar to spraying. The spraying device will occupy additional volume of the refrigerator, reducing the performance of the refrigerator. Or, to meet the installation of the spraying device, the refrigerator is designed with a special refrigerator shape, resulting in a large difference in the appearance of the refrigerator, which has no market competitive advantage.

[0036] Please refer to Figure 1 and Figure 2 , in particular, in the present embodiment, a self-cleaning refrigerator 10 includes a cabinet 11, a shelf 12, a cleaning element 13 and a flexible tube 14.

[0037] The cabinet 11 is the main structure of the refrigerator. The cabinet 11 is used to store goods. And the cabinet 11 can include a refrigeration chamber 111 and a freezing chamber 112. The refrigeration chamber 111 is used to store goods in refrigeration, and the temperature of the refrigeration chamber 111 is usually above 0 degrees Celsius. The freezing chamber 112 is used to store goods in freezing, and the temperature of the freezing chamber 112 is below 0 degrees Celsius. And for different types of refrigerators, the refrigeration chamber 111 and the freezing chamber 112 of the cabinet 11 can be distributed vertically or horizontally, and the type of the cabinet 11 is not limited here. That is, the cabinet 11 can be a double-door type or a single-door type. And for convenience of description, it is now defined that the two ends of the cabinet 11 correspond to the two end faces in the front-rear direction of the cabinet 11. The opening door of the cabinet 11 corresponds to the front face of the cabinet 11. The back of the cabinet 11 is the closed end opposite to the opening door. The two sides of the cabinet 11 correspond to the two side faces of the cabinet 11 in the left-right direction.

[0038] The shelf 12 is arranged in the cabinet 11. The shelf 12 divides the cabinet 11 into multiple spaces. In particular, in the present embodiment, the shelf 12 is detachably arranged on the cabinet 11. And the shelf 12 can be a shelf of the refrigeration chamber 111 or a shelf of the freezing chamber 112; or the shelf 12 can be a bottom plate of a drawer of the refrigeration chamber 111 or a bottom plate of a drawer of the freezing chamber 112.

[0039] Specifically, in the embodiment, the structure of the storage plate 12 is a plate structure such as a partition plate, a shelf, or the like. The storage plate 12 is described by way of example of a glass plate or a plastic plate. When the storage plate 12 is a bottom plate of a drawer, the cleaning manner and process of the self-cleaning refrigerator 10 on the bottom plate of the drawer are similar to those on the partition plate, which will not be described herein again.

[0042] Referring to Figure 5 The self-cleaning refrigerator 10 further includes a first rotating cover 15. The first rotating cover 15 can be rotatably arranged on the cleaning member 13. In the daily use of the refrigerator, the refrigerator does not need to be cleaned at any time. When the cleaning member 13 does not need to be cleaned, the first rotating cover 15 covers the cleaning member 13 to shield the cleaning member 13. From the appearance, there is no difference between the ordinary storage plate 12 and the first rotating cover 15, which is equivalent to the edge design of the storage plate 12, and does not affect the daily use of the refrigerator. When the cleaning member 13 needs to be cleaned, the driving motor drives the first rotating cover 15 to rotate and open, so as to facilitate the cleaning member 13 to enter and exit.

[0043] Referring to Figure 6 In addition, specifically, in the embodiment, the first rotating cover 15 can be driven to rotate by the driving motor. The first rotating cover 15 is provided with an arc-shaped portion 151 and a rotating shaft 152. The arc-shaped portion 151 is rotatably connected with the side clamping strip 122 through the rotating shaft 152. The motor drives the arc-shaped portion 151 to rotate around the rotating shaft 152. Thus, the purpose of opening and closing the arc-shaped portion 151 is achieved. The arc-shaped portion 151 forms a receiving cavity for accommodating the cleaning member 13. In addition, the appearance of the arc-shaped portion 151 is smooth, so that the connection between the first rotating cover 15 and the storage plate 12 is smoothly transitioned. Specifically, in the embodiment, the corresponding circular arc shape of the arc-shaped portion 151 is a quarter circular arc shape.

[0044] The flexible tube 14 has good ductility. The flexible tube 14 can be a rubber tube, a plastic tube, etc. The flexible tube 14 is fixed to the cleaning member 13, and the cleaning member 13 drives the flexible tube 14 to move.

[0045] Please refer to Figure 2 , the flexible tube 14 can include a water pipe. The water pipe is used to access cleaning water. Specifically, in the embodiment, the self-cleaning refrigerator 10 further includes a water inlet pipe 142 and a pump body 144. The pump body 144 communicates with the water inlet pipe 142. Please refer to Figure 9 and Figure 10 , the water inlet pipe 142 communicates with a container containing cleaning water through a water inlet 143. The pump body 144 can pump cleaning water into the water inlet pipe 142. The water inlet pipe 142 is introduced into the cabinet 11 from the rear of the cabinet 11.

[0046] Please refer to Figure 7 , specifically, the rear of the cabinet 11 can be provided with a groove 114 for accommodating the water inlet pipe 142, so as to facilitate the arrangement of the water inlet pipe 142. The flexible tube 14 is sealingly connected with the water inlet pipe 142 through a sealing rubber joint. The water inlet of the water inlet pipe 142 is located at the right side of the refrigerating chamber 111 and the freezing chamber 112. The water inlet pipe 142 is arranged along the right side of the refrigerating chamber 111 and the freezing chamber 112.

[0047] The flexible tube 14 is provided with water outlets, and the cleaning member 13 moves along the shelf plate 12, while the water discharged from the water outlets washes the shelf plate 12.

[0048] The flexible tube 14 includes a first end and a second end. The first end of the flexible tube 14 is used for water inlet, and the water outlets are arranged at the second end of the flexible tube 14. Moreover, the water outlets are multiple, the diameters of the multiple water outlets gradually increase along the extension direction of the flexible tube 14, and the diameter of the water outlet close to the second end of the flexible tube 14 is larger than that of the water outlet close to the first end of the flexible tube 14. Therefore, it can be ensured that the water flow size of each water outlet is balanced, the surface of the shelf plate 12 can be uniformly sprayed with cleaning water, and the overall cleaning effect of the shelf plate 12 can be ensured.

[0049] Moreover, the flexible tube 14 can further include an air pipe. The air pipe can be provided with air outlets. The air outlets are used to spray air outward. The air spray can be used to concentrate the cleaning of residual water on the shelf plate 12, or can be used to flush stubborn stains on the shelf plate 12.

[0050] Please refer to Figure 4 and Figure 5The side of the storage plate 12 is provided with a guide rail 16 extending from one side edge to the other side edge of the storage plate 12, and the cleaning member 13 is movably arranged on the guide rail 16. The guide rail 16 can be a sliding groove, a limiting groove or the like. The cleaning member 13 can slide or roll along the guide rail 16. As long as the movement of the cleaning member 13 can be limited and guided, it is acceptable.

[0051] In addition, the self-cleaning refrigerator 10 further comprises a second rotating cover 17. The second rotating cover 17 is rotatably arranged on the guide rail 16. The second rotating cover 17 is rotatably arranged on the rear clamping strip 121. Similarly, the second rotating cover 17 is rotatably connected with the rear clamping strip 121 through a rotating shaft. The driving motor drives the rotating shaft to rotate, thereby controlling the opening and closing of the second rotating cover 17. Therefore, when the refrigerator does not need to be cleaned, and the cleaning member 13 does not need to move along the guide rail 16, the second rotating cover 17 covers the guide rail 16 to shield and protect the guide rail 16. From the appearance, the storage plate 12 is the same as the ordinary storage plate 12, and the second rotating cover 17 is equivalent to the edge covering design of the storage plate 12, which does not affect the daily use of the refrigerator. When the cleaning member 13 needs to be cleaned, the driving motor drives the second rotating cover 17 to rotate and open, so that the guide rail 16 is exposed, and then the cleaning member 13 can move along the guide rail 16 to perform the cleaning operation.

[0052] Please refer to Figure 8 In other embodiments, one end of the cleaning member 23 is rotatably arranged on one side edge of the storage plate 22, and the cleaning member 23 rotates along the surface of the storage plate 22. The cleaning surface of the cleaning member 23 is fan-shaped. Then, the cleaning member 23 can be multiple. Specifically, the cleaning member 23 is two, and the two cleaning members 23 are oppositely arranged at two top corners of the storage plate 22. The length of the cleaning member 23 can be the length of the side edge of the storage plate 22. Then, the rotation of the cleaning member 23 can reach the maximum cleaning area. The cleaning members 23 located at the two top corners can correspond to a fan-shaped cleaning area respectively. The two fan-shaped cleaning surfaces have a mutual overlapping part, so as to ensure that the cleaning member 23 can completely clean the surface of the entire storage plate 22. In addition, the movement of the two cleaning members 23 needs to be alternately performed, so as to avoid the mutual interference of the two cleaning members 23 when they move simultaneously.

[0053] It can be understood that the cleaning member 23 can also be three, four or the like. As long as the cleaning surfaces corresponding to the multiple cleaning members 13 can completely cover the surface of the storage plate 22, the cleaning of the entire storage plate 22 can be completed.

[0054] Specifically, in the present embodiment, the storage plate 12 can be a partition plate. A water leakage hole is formed on one side of the storage plate 12, and a water collecting groove 18 is arranged below the water leakage hole. When the cleaning member 13 moves from one side of the partition plate to the other side, the cleaning water will be pushed to one side of the partition plate, and water accumulation will be formed on one side of the partition plate. The accumulated water can be discharged from the water leakage hole to complete the cleaning.

[0055] It can be understood that the water leakage hole can be multiple, and the opposite sides of the partition plate can be provided with water leakage holes. When the cleaning piece 13 reciprocates on the partition plate, the accumulated water on both sides of the partition plate can be discharged from the water leakage hole. The shape of the water leakage hole can be circular, square, etc. The shape of the water leakage hole is not limited here.

[0056] Please also refer to Figure 9 and Figure 10 , the water collecting groove 18 is arranged relative to the water leakage hole, used to receive the dirty water leaked from the water leakage hole. And the water collecting groove 18 is in communication with the dirty water box 19. The water collecting groove 18 and the dirty water box 19 can be communicated through the water outlet pipe 146. Also, please refer to Figure 7 , the inner side of the box body 11 is provided with a groove 114 for accommodating the water outlet pipe 146. The groove 114 can facilitate the arrangement of the water outlet pipe 146, avoiding occupying the accommodation space of the box body 11. And the water outlet pipe 146 is arranged on the left side of the refrigeration chamber 111 and the freezing chamber 112. The water outlet 147 of the water outlet pipe 146 is located in the dirty water box 19.

[0057] The dirty water box 19 can be detachably arranged on the box body 11. It can be convenient to take out the dirty water box 19 and pour out the dirty water. Specifically, the box body 11 further comprises a pressing machine warehouse. The pressing machine warehouse is provided with a pressing machine supporting plate. The dirty water box 19 is detachably arranged at the lower right position of the pressing machine warehouse. The dirty water box 19 can be fixed by the pressing machine supporting plate. It can be understood that the dirty water box 19 can be detachably arranged on the pressing machine supporting plate by sliding rail or buckle.

[0058] And the water collecting groove 18 and the dirty water box 19 are arranged close to the refrigeration chamber 111. It can be avoided that the water temperature in the water collecting groove 18 and the dirty water box 19 is affected by the freezing chamber 112. The dirty water in the water collecting groove 18 and the dirty water box 19 may freeze, affecting the cleaning function of the self-cleaning refrigerator 10.

[0059] Please refer to Figure 11 , the self-cleaning refrigerator 10 of the embodiment further comprises a detection unit 101 and a controller 102. The detection unit is used to detect whether there is storage on the shelf 12, and the detection unit 101 is electrically connected with the controller 102. The controller 102 is pre-set with a cleaning program. When the detection unit 101 detects that there is no storage on the shelf 12, the controller 102 starts the self-cleaning program. The controller 102 controls the movement of the cleaning piece 13. It can be understood that the detection unit 101 can be an infrared detector, a gravity sensor, etc.

[0060] And, the controller 102 can be electrically connected with the pump body 144. When the self-cleaning program is started, the controller 102 controls the pump body 144 to start, and the pump body 144 starts to pump the cleaning water into the flexible pipe 14.

[0061] And, the controller 102 is also electrically connected with the motor 103 which controls the opening and closing of the first rotating cover 15 and the second rotating cover 17. When the self-cleaning program is started, the controller 102 controls the motor 103 to start, and the motor 103 operates to open the first rotating cover 15 and the second rotating cover 17 on the storage plate 12.

[0062] And, the controller 102 is also electrically connected with the driving member 131. When the driving member 131 drives the cleaning member 13 to move along the guide rail 16, it is ensured that the first rotating cover 15 and the second rotating cover 17 have been opened, and the cleaning water in the flexible pipe 14 is pumped. After the cleaning water in the flexible pipe 14 is sprayed on the surface of the storage plate 12, the driving member 131 drives the cleaning member 13 to move along the guide rail 16.

[0063] Now, the self-cleaning refrigerator 10 is described in combination with the working process of the self-cleaning refrigerator 10. First, when the detection unit 101 judges that there is no storage on the storage plate 12, the controller 102 controls the self-cleaning program to start. Please refer to Figure 12 , the controller 102 controls the pump body 144 to pump the cleaning water into the flexible pipe 14. The controller 102 controls the motor 103, and the motor 103 operates to open the first rotating cover 15 and the second rotating cover 17 on the storage plate 12. The driving member 131 drives the cleaning member 13 to move along the guide rail 16 from one side of the storage plate 12 to the other side. Before the cleaning member 13 moves, the cleaning water in the flexible pipe 14 is sprayed on the surface of the storage plate 12. The dirty water after brushing the storage plate 12 enters the dirty water box 19 along the water leakage hole and the water receiving groove 18.

[0064] Therefore, the self-cleaning refrigerator 10 can realize the cleaning of the storage plate 12, and can clean the storage plate 12 in time and automatically, so as to ensure that the storage plate 12 can be kept clean. Therefore, the self-cleaning refrigerator can also clean the shelves, drawers and the like in time, so as to ensure the cleanliness of the shelves and the drawers, and make the self-cleaning refrigerator safer and more sanitary.
