[0002] A refrigerator is a device that keeps food or other items in a constant low-temperature state to extend their shelf life. A refrigerator is not a safe cabinet for food preservation. Bacteria carried by the food itself and bacteria in the air will gradually contaminate the refrigerator, making it a hotbed for bacterial growth. Bacterial growth will not only accelerate the corruption of food, but also may cause bacterial infection to users, seriously endangering their health. Therefore, refrigerator sterilization technology has always been one of the key research directions of the industry.

Therefore, the industry usually adopts this technical solution in a small space, and it is difficult to kill bacteria in the entire space. Plasma ozone sterilization and photocatalytic sterilization are good for air sterilization, but they are not effective for the surface of objects and food surfaces, and cannot effectively remove bacteria that grow in the refrigerator.

[0040] In order to enable 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 clearly and completely described 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 of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work should fall within the scope of protection of the present application.

[0041] The refrigerator is not a safe cabinet for food preservation. The bacteria carried by the food itself and the bacteria in the air will gradually contaminate the refrigerator, making it a hotbed for bacterial growth. Bacterial growth will not only accelerate the corruption of food, but also may cause bacterial infection to users, seriously endangering their health. Therefore, refrigerator sterilization technology has always been one of the key research directions of the industry. Refrigerator sterilization technologies usually include ultraviolet sterilization, plasma ozone sterilization, photocatalytic sterilization, etc. Ultraviolet sterilization can quickly kill bacteria on the surface of objects, but there are risks such as human harm and material aging. Therefore, the industry usually adopts this technical solution in a small space, and it is difficult to achieve bacterial killing in the entire space. Plasma ozone sterilization and photocatalytic sterilization have good sterilization effects on air, but they are not effective on the surface of objects and food surfaces, and cannot effectively remove bacteria growing in the refrigerator.

[0042] In CN111426135A, an ultraviolet lamp is set at the air inlet bifurcation to sterilize the gas in the air duct, but it is difficult to remove bacteria on the surface of objects in the refrigerator; in CN216769181U, a purple lamp is integrated into the surface light source of the refrigerator, but the wavelength of the purple lamp is 400-410nm, and the actual sterilization effect is not good; in CN113513867A, an ultraviolet lamp is designed in an independent small space in the refrigerator door panel to solve the problems of material aging and human body injury, but it is difficult to achieve surface sterilization in the entire refrigerator space and the cold storage room; in CN215983458U, a shielding door panel is designed to prevent the ultraviolet lamp on the top or both sides from causing damage to the human body, but the aging effect of the ultraviolet lamp on the refrigerator liner and other materials is not taken into account.

[0043] UV sterilization in refrigerators can effectively kill bacteria on the surface of objects, but considering the problems of material aging and human harm, the industry generally uses it in small spaces, which greatly limits the scope of UV sterilization. How to achieve efficient sterilization in the entire space and a large range while avoiding material aging and human harm is an urgent problem to be solved in the industry.

[0044] The technical problem to be solved by the present application is to overcome the problem of efficient surface sterilization in the whole space of refrigerators in the prior art, and to provide a surface sterilization method that is safe for human body and reliable for products. The surface sterilization in the whole space is achieved by irradiating ultraviolet light on the refrigerator flip beam, and human harm is avoided by the structural shielding design of the flip beam and the power-off of the moving structure of the refrigerator flip beam when the door is opened. Material aging is avoided by the design of ultraviolet light propagation and the irradiation angle of ultraviolet lamp beads.

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

[0046] Reference Figure 1-Figure 4 As shown, the embodiment of the present application provides a full-space ultraviolet sterilization refrigerator, including a refrigerator body 10, a door body 30 arranged on the refrigerator body 10, a flip beam 50 arranged on the door body 30, and an ultraviolet lamp 60 arranged on the flip beam 50;

[0047] The refrigerator body 10 is a conventional refrigerator, which may be a rectangular box. The refrigerator body 10 is provided with a cabin 20, and a plurality of cabins 20 may be provided. The cabin 20 includes a fresh-keeping compartment.

[0048] The door body 30 matches the refrigerator body 10, the door body 30 is hinged on the refrigerator body 10, and the door body 30 is located at the open end of the compartment 20. The door body 30 is used to open or close the compartment 20. The inner wall of the door body 30 is provided with an inner liner 40. The inner liner 40 is provided with a flange 41 perpendicular to the door body 30 and extending into the compartment 20 on the side close to the refrigerator body 10. The flange 41 is a plate-shaped structure.

[0049] The flip beam 50 is detachably mounted on the door body 30, and the flip beam 50 is rotatably connected to the refrigerator body 10. The flip beam 50 has a mounting surface 51, and the mounting surface 51 is located on the inner side of the flip beam 50, and the mounting surface 51 is perpendicular to the flange 41;

[0050] The ultraviolet lamp 60 can be a conventional ultraviolet disinfection lamp, and the ultraviolet lamp 60 is arranged on the mounting surface 51 of the flip beam 50, and the ultraviolet lamp 60 is embedded in the flip beam 50, and the light-emitting end of the ultraviolet lamp 60 extends out of the mounting surface 51. A plurality of ultraviolet lamps 60 are evenly distributed in the vertical direction;

[0051] When the door body 30 is in a closed state, the flip beam 50 is parallel to the door body 30, the mounting surface 51 of the flip beam 50 faces the cabin 20 and is perpendicular to the flange 41, and the ultraviolet light emitted by the ultraviolet lamp 60 enters the cabin 20, thereby achieving efficient sterilization in the entire space and a wide range;

[0052] When the door body 30 is in an open state, the mounting surface 51 of the flip beam 50 is perpendicular to the door body 30 and parallel to the flange 41. The ultraviolet lamp 60 is located between the flip beam 50 and the inner liner 40. The flange 41 blocks the ultraviolet lamp 60 to prevent ultraviolet rays from harming the human body.

[0053] In some embodiments, a control system is provided in the refrigerator body 10, and the control system may be a conventional refrigerator control system. The control system controls the switch of the ultraviolet lamp 60, and the control system includes a manual operation module, through which the switch of the ultraviolet lamp 60 can be controlled.

[0054] Further, in some embodiments, the full-space ultraviolet sterilization refrigerator further includes a control switch, which is disposed on the refrigerator body 10 and / or the door body 30, and the control switch may be a micro switch, an infrared sensor, etc. The control system, the control switch, and the ultraviolet lamp 60 are electrically connected in sequence;

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

[0056] When the door body 30 is in an open state, the control switch is in an off state, and the ultraviolet lamp 60 is powered off and does not work, thereby preventing the ultraviolet rays from irradiating the user and avoiding harm to the human body.

[0057] The structure designed in this application can effectively prevent the control system from running wrong, resulting in the UV light source not being cut off and causing accidental harm to the human body. At the same time, a metal contact switch or a magnetic switch can be designed on the guide column at the top of the flip beam and the refrigerator body. When the refrigerator door is opened, the switch is disconnected and the UV light is powered off and does not work; when the refrigerator door is closed, the switch is closed and the UV light can be operated or disconnected according to actual needs.

[0058] like Figure 3 and Figure 4 As shown in the figure, A1 is the uppermost ultraviolet light emitted by the ultraviolet lamp 60, and A2 is the lowermost ultraviolet light emitted by the ultraviolet lamp 60. In a feasible implementation, the ultraviolet lamp 60 irradiates downward at a certain angle α, that is, the angle between the ultraviolet lamp 60 and the mounting surface 51 is α, and the irradiation angle of the ultraviolet lamp 60 is β, that is, the wide angle of the longitudinal section of the irradiation area of ​​the ultraviolet lamp 60 is β, and the angle between the uppermost ultraviolet light emitted by the ultraviolet lamp 60 and the top inner wall of the refrigerator body 10 is γ, γ<15°, and the angle between the lowermost part of the ultraviolet light and the door body 30 is δ, which must satisfy 10°≤δ≤60°.

[0059] Furthermore, the full-space ultraviolet sterilization refrigerator further includes a shelf, which may be a conventional support frame, and the shelf is disposed in the refrigerator body 10;

[0060] The α=30°, β=60°, that is, the ultraviolet lamp 60 irradiates each layer of the shelf downward at 30°, and the irradiation angle of the ultraviolet lamp 60 is 60°.

[0061] In some embodiments, γ=0°, δ=30°, that is, the angle between the uppermost part of the ultraviolet light emitted by the ultraviolet lamp 60 and the top inner wall of the refrigerator body 10 is 0°, and the angle between the lowermost part of the ultraviolet light and the door body 30 is 30°.

[0062] According to the fact that light propagates in a straight line, the present application selects an appropriate UV lamp irradiation angle and UV lamp installation method, so that the refrigerator liner is exposed to the UV lamp as little as possible. The UV lamp irradiates downward at a certain angle α, the UV lamp irradiation angle is β, the angle γ between the uppermost part of the UV light and the top plane of the refrigerator is less than 15°, and the angle between the lowermost part of the UV light and the refrigerator door must meet 10°≤δ≤60°

[0063] In some embodiments, three ultraviolet lamps 60 are provided, and the three ultraviolet lamps 60 are evenly arranged on the mounting surface 51 of the flip beam 50 along the vertical direction.

[0064] In some embodiments, there are three flanges 41, and the three flanges 41 correspond to the three ultraviolet lamps 60 one by one;

[0065] Alternatively, the flange 41 is provided with one, and the flange 41 extends from the bottom of the inner liner 40 to the top of the inner liner 40 , and the flange 41 shields the three ultraviolet lamps 60 .

[0066] In some embodiments, the flange 41 and the liner 40 are an integrated structure. During production, the flange 41 and the liner 40 are integrally formed. The integral forming is convenient to produce and has a stable structure.

[0067] In some embodiments, the flange 41 is detachably connected to the inner liner 40 , and the flange 41 and the inner liner 40 are separate structures.

[0068] In some embodiments, the flange 41 has a connecting surface, and the connecting surface of the flange 41 is fixed to the inner liner 40 by adhesive.

[0069] In some embodiments, through holes are provided on the upper and lower sides of the flange 41 in the vertical direction, and screw holes are provided on the inner liner 40. The two screw holes are equivalent to the two through holes. Bolts pass through the through holes and are screwed to the corresponding screw holes, so that the flange 41 and the inner liner can be detachably connected and fixed by bolts, and the structure is stable.

[0070] In some embodiments, a clamping piece is provided on the inner wall of the liner 40, and the clamping piece may be L-shaped, and the clamping piece includes a connecting portion and a plug-in portion, one end of the connecting portion is fixedly connected or detachably connected to the inner wall of the liner 40, the other end of the connecting portion extends laterally and is fixedly connected to one end of the plug-in portion, and the other end of the plug-in portion extends vertically upward;

[0071] The side surface of the flange 41 is a snap-fit ​​surface, and the snap-fit ​​surface is a plane. The bottom end of the flange 41 is provided with a plug hole, and the plug hole matches the plug-in portion;

[0072] The engaging surface of the flange 41 fits against the inner wall of the inner liner 40 , and the flange 41 moves vertically downward so that the plug-in portion is inserted into the plug hole, thereby fixing the flange 41 on the inner liner 40 .

[0073] The flange 41 is connected to the inner container 40 via the clamping piece, and the flange 41 is easy to install or remove.

[0074] In some embodiments, the inner container 40 is made of impact-resistant polystyrene material to prevent ultraviolet light from causing yellowing and aging of the refrigerator inner container.

[0075] The full-space ultraviolet sterilization refrigerator provided by the present application is designed with the ultraviolet lamp on the flip beam, which cleverly blocks the ultraviolet lamp when the door is opened, thereby preventing the control system from failing and irradiating the human body;

[0076] By designing the UV irradiation angle and the UV lamp installation angle, we can prevent UV rays from irradiating the refrigerator inner tank and causing aging of the material.

[0077] This application achieves surface sterilization in the entire refrigeration space of the refrigerator, and avoids the harm of ultraviolet light to the human body through structural design and control logic design. At the same time, by designing the irradiation angle and installation angle of the ultraviolet lamp, it avoids the aging of the refrigerator liner material caused by ultraviolet light.

At this time, the flip beam 50 is parallel to the door body 30, and the mounting surface 51 of the flip beam 50 faces the cabin 20 and is perpendicular to the flange 41. The ultraviolet light emitted by the ultraviolet lamp 60 is injected into the cabin 20, thereby achieving efficient sterilization in the entire space and a large range;

[0081] When the door body 30 is in an open state, the mounting surface 51 of the flip beam 50 is perpendicular to the door body 30 and parallel to the flange 41, the ultraviolet lamp 60 is located between the flip beam 50 and the inner liner 40, the flange 41 blocks the ultraviolet light emitted by the ultraviolet lamp 60, and at this time, the control switch is in an off state, the ultraviolet lamp 60 is powered off and does not work, thereby preventing ultraviolet rays from irradiating the user and avoiding harm to the human body.
