[0040] In order for those skilled in the art to better understand the technical solutions in the present application, the technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor should be within the scope of protection of the present application.

[0041] The refrigerator is not a safe cabinet for food preservation. Bacteria carried by food materials and bacteria in the air will gradually contaminate the refrigerator, making the refrigerator a breeding ground for bacteria. Bacterial growth not only accelerates the spoilage of food materials, but also can cause bacterial infection of users, seriously endangering health. Therefore, refrigerator sterilization technology has always been one of the key research directions in the industry. The refrigerator sterilization technology usually has ultraviolet sterilization, plasma ozone sterilization, photocatalytic sterilization, etc. Ultraviolet sterilization can quickly kill the surface of the object, but there are risks of human injury and material aging, so the industry usually adopts this technical solution in a small space, and it is difficult to achieve sterilization in the full space. Plasma ozone sterilization and photocatalytic sterilization have good air sterilization effect, but the sterilization effect on the surface of the object and the surface of the food material is not good, and the bacteria breeding in the refrigerator cannot be effectively removed.

[0042] CN111426135A adopts ultraviolet lamp to be arranged at the air inlet bifurcation, sterilize the gas in the air duct, it is difficult to remove the bacteria on the surface of the refrigerator; CN216769181U integrates the ultraviolet lamp in the refrigerator surface light source, but the wavelength of the ultraviolet lamp is 400-410nm, and the actual sterilization effect is poor; CN113513867A designs the ultraviolet lamp in the refrigerator door panel to solve the material aging and human injury problem, but it is difficult to realize the sterilization of the material of the refrigerator liner and the material of the refrigerator liner.

[0043] The refrigerator ultraviolet sterilization can efficiently kill the bacteria on the surface, but considering the material aging, human injury and other problems, the industry generally uses in small space, so that the effective range of ultraviolet sterilization is greatly limited. How to realize efficient sterilization in full space and large range while avoiding material aging and human injury is a problem to be solved in the industry.

[0044] The technical problem to be solved by the present application is to overcome the problem of full-space efficient surface sterilization of the refrigerator in the prior art, and to provide a human-safe and reliable product surface sterilization method. The full-space surface sterilization is realized by the ultraviolet lamp irradiation carried by the refrigerator turnover beam, the human injury is avoided by the structure shielding design of the turnover beam and the power-off of the turnover beam movement structure when the refrigerator is opened, and the material aging is avoided by the design of ultraviolet light propagation and ultraviolet lamp bead irradiation angle.

[0045] The specific structure of the full-space ultraviolet sterilization refrigerator provided by the present application is described in detail below with reference to the accompanying drawings.

[0046] Referring to Figures 1-4 The full-space ultraviolet sterilization refrigerator provided by the present application includes a refrigerator main body 10, a door body 30 arranged on the refrigerator main body 10, a turnover beam 50 arranged on the door body 30, and an ultraviolet lamp 60 arranged on the turnover beam 50.

[0047] The refrigerator main body 10 is a conventional refrigerator, which can be a rectangular box body. The refrigerator main body 10 is provided with a cabin 20, and the cabin 20 can be provided with a plurality of cabin 20. The cabin 20 includes a fresh-keeping bin.

[0048] The door body 30 is matched with the refrigerator main body 10, and the door body 30 is hinged to the refrigerator main body 10. The door body 30 is located at the open end of the cabin 20, and the door body 30 is used to open or close the cabin 20. The inner wall of the door body 30 is provided with an inner liner 40. The inner liner 40 is provided with a turnover edge 41 which is perpendicular to the door body 30 and extends into the cabin 20. The turnover edge 41 is a plate structure.

[0049] The turnover beam 50 is detachably arranged on the door body 30, and is rotatably connected with the refrigerator main body 10. The turnover beam 50 has a mounting surface 51 located on the inner side of the turnover beam 50. The mounting surface 51 is perpendicular to the turnover edge 41.

The light-emitting end of the ultraviolet lamp 60 extends out of the mounting surface 51. The plurality of ultraviolet lamps 60 are uniformly distributed in the vertical direction.

[0051] When the door body 30 is in the closed state, the turnover beam 50 is parallel to the door body 30. The mounting surface 51 of the turnover beam 50 faces the cabin 20 and is perpendicular to the turnover edge 41. The ultraviolet light emitted by the ultraviolet lamp 60 enters the cabin 20, thereby achieving efficient sterilization in the whole space and a large range.

[0052] When the door body 30 is in the open state, the mounting surface 51 of the turnover beam 50 is perpendicular to the door body 30 and parallel to the turnover edge 41. The ultraviolet lamp 60 is located between the turnover beam 50 and the inner container 40. The turnover edge 41 shields the ultraviolet lamp 60 to avoid damage to the human body by ultraviolet light.

[0055] When the door body 30 is in the closed state, the control switch is in the closed state, and the ultraviolet lamp 60 is powered on to work. The ultraviolet light emitted by the ultraviolet lamp 60 irradiates in the cabin 20, thereby achieving efficient sterilization in the whole space and a large range.

[0056] When the door body 30 is in the open state, the control switch is in the open state, and the ultraviolet lamp 60 is powered off to not work, thereby avoiding irradiation of the user by the ultraviolet light and avoiding damage to the human body.

[0057] The structure can effectively prevent the control system from running error, causing the ultraviolet light source not to be cut off and causing accidental injury to the human body. Meanwhile, the guide column at the top of the turnover beam and the refrigerator body can be designed with a metal contact switch or a magnetic attraction type switch. When the refrigerator door is opened, the switch is turned off, the ultraviolet lamp is powered off and does not work; when the refrigerator door is closed, the switch is closed, and the ultraviolet lamp can operate or be turned off according to actual needs.

[0059] Further, the full-space ultraviolet sterilization refrigerator further comprises shelves, which can be conventional support shelves, and the shelves are arranged in the refrigerator body 10.

[0060] The a = 30° and β = 60°, that is, the ultraviolet lamp 60 is downwardly irradiated at an angle of 30° to each of the shelves, and the irradiation angle of the ultraviolet lamp 60 is 60°.

[0062] According to the straight-line propagation of light, the application selects appropriate irradiation angles of the ultraviolet lamp and mounting modes of the ultraviolet lamp, so that the inner tank of the refrigerator receives as little irradiation of the ultraviolet lamp as possible. The ultraviolet lamp is downwardly irradiated at an angle a, the irradiation angle of the ultraviolet lamp is β, the included angle between the uppermost ultraviolet light and the top plane of the refrigerator is γ < 15°, and the included angle between the lowermost ultraviolet light and the refrigerator door body needs to satisfy 10° ≤ δ ≤ 60°.
