Description

Technical Field

[0001] This utility model belongs to the field of freezer technology, specifically relating to a freezer with ultraviolet sterilization function. Background Technology

[0002] A freezer is a refrigeration device used to store frozen food or low-temperature items. The freezer uses a refrigeration system to compress the refrigerant into a high-temperature, high-pressure gas using a compressor. After the gas is cooled by the condenser, it becomes a liquid. Then, it passes through a throttling valve to reduce the pressure and enters the evaporator, where it absorbs heat and evaporates into a gas. This process lowers the internal temperature of the freezer and achieves the purpose of refrigeration and preservation.

[0003] However, when using a freezer, placing different types of food together in the same freezer can easily lead to cross-contamination. For example, fresh food containing bacteria may transfer a large number of microorganisms to other processed or packaged foods. Since freezers lack sterilization functions, they cannot start the sterilization process in time when contamination occurs, thus failing to effectively control the risk and posing a great challenge to food hygiene and safety.

[0004] To address the aforementioned issues, this application proposes a freezer with ultraviolet sterilization functionality. Utility Model Content

[0005] To address the aforementioned problems in the existing technology, this utility model provides a freezer with ultraviolet sterilization function, which enables the freezer to sterilize.

[0009] As a preferred embodiment of this utility model, the front and back of the sliding frame are fixedly connected with assist plates, and both sides of each assist plate are in contact with the inner wall of the limiting frame.

[0010] As a preferred embodiment of this utility model, the outer surface of the second ultraviolet germicidal lamp is fixedly connected with two fixing rings, and the two fixing rings are respectively fixedly connected to the inner bottom wall and the inner top wall of the sliding frame on opposite sides.

[0011] As a preferred technical solution of this utility model, the interior of the freezer is provided with two sets of mounting plates, and each mounting plate is fitted with two fixing pins. The ends of each set of fixing pins that are far apart from each other pass through the freezer and extend into the interior of the freezer.

[0012] As a preferred technical solution of this utility model, two fixing brackets are fixedly connected to one side of each set of mounting plates that are close to each other, and the inner wall of each set of fixing brackets is fixedly connected to the outer surface of the first ultraviolet germicidal lamp.

[0013] As a preferred technical solution of this utility model, a protective frame is fixedly connected to one side of each set of mounting plates that are close to each other, and each protective frame is sleeved on the outside of the first ultraviolet germicidal lamp.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0024] Please see Figure 1-6 The present invention provides the following technical solution: a freezer with ultraviolet sterilization function, including a freezer 1, a controller 5 is provided on the left side of the freezer 1, two first racks 6 are fixedly connected to the inner bottom wall of the freezer 1, each first rack 6 is slidably connected to a sliding block 10, a second rack 8 and two sets of first ultraviolet sterilization lamps 16 are respectively provided inside the freezer 1, the upper surfaces of the two sliding blocks 10 are fixedly connected to the bottom surface of the second rack 8, a limit frame 7 is slidably connected inside the second rack 8, a sliding frame 11 is slidably connected inside the limit frame 7, and a second ultraviolet sterilization lamp 13 is provided inside the sliding frame 11;

[0025] In this embodiment, the sliding block 10 sliding in the first slot 6, the limiting frame 7 sliding in the second slot 8, and the sliding frame 11 sliding in the limiting frame 7 all have frictional force. Without applying force, the moved position can be limited by frictional force. At the same time, the first ultraviolet germicidal lamp 16 and the second ultraviolet germicidal lamp 13 mainly emit ultraviolet rays of specific wavelengths. When microorganisms are irradiated, the ultraviolet rays penetrate their cell walls and cell membranes and act on their internal genetic material. The ultraviolet energy causes pyrimidine bases to form pyrimidine dimers, which destroy the structure and function of the genetic material, making it impossible for microorganisms to replicate, transcribe, and synthesize proteins normally, thus losing their reproductive capacity and eventually dying, achieving sterilization and disinfection.

[0026] Specifically, two sets of wheel frames 2 are fixedly connected to the bottom surface of the freezer 1. Each wheel frame 2 has a rotating wheel 3 rotatably connected to its inner wall. In this embodiment, the rotating wheel 3 can be fixed to the freezer 1 through the wheel frame 2, and the freezer 1 can be moved easily by using the rotating wheel 3.

[0027] Specifically, a connecting plate 4 is fixedly connected to the right side of the controller 5, and the right side of the connecting plate 4 is fixedly connected to the left side of the freezer 1. In this embodiment, the controller 5 can be fixed to the freezer 1 through the connecting plate 4. The controller 5 refers to the master control device that controls the starting, speed adjustment, braking and reversing of the motor by changing the wiring of the main circuit or control circuit and changing the resistance value in the circuit according to a predetermined sequence.

[0028] Specifically, the front and back of the sliding frame 11 are fixedly connected with assist plates 12. Both sides of each assist plate 12 are in contact with the inner wall of the limiting frame 7. In this embodiment, the assist plates 12 can facilitate the sliding of the sliding frame 11 within the limiting frame 7, thereby improving the convenience of sliding adjustment of the sliding frame 11.

[0029] Specifically, two fixing rings 14 are fixedly connected to the outer surface of the second ultraviolet germicidal lamp 13. The two fixing rings 14 are fixedly connected to the inner bottom wall and the inner top wall of the sliding frame 11 respectively on their opposite sides. In this embodiment, the fixing rings 14 can fix the second ultraviolet germicidal lamp 13 into the sliding frame 11, thereby enabling the second ultraviolet germicidal lamp 13 to be used stably.

[0030] Specifically, the interior of the freezer 1 is provided with two sets of mounting plates 9. Each mounting plate 9 is fitted with two fixing pins 18. The ends of each set of fixing pins 18 that are far apart from each other pass through the freezer 1 and extend into the interior of the freezer 1. In this embodiment, the mounting plates 9 can be fixed to the interior of the freezer 1 by means of fixing pins 18, so that the mounting plates 9 can be installed in the freezer 1 for use.

[0031] Specifically, each set of mounting plates 9 has two fixed brackets 15 fixedly connected to one side of each other. The inner wall of each set of fixed brackets 15 is fixedly connected to the outer surface of the first ultraviolet germicidal lamp 16. In this embodiment, the first ultraviolet germicidal lamp 16 can be fixed to the mounting plate 9 through the fixed brackets 15, so that the first ultraviolet germicidal lamp 16 can be fixed in the freezer 1 for stable use.

[0032] Specifically, each set of mounting plates 9 has a protective frame 17 fixedly connected to one side of each other. Each protective frame 17 is fitted over the outside of the first ultraviolet germicidal lamp 16. In this embodiment, the first ultraviolet germicidal lamp 16 can be protected by the protective frame 17, and the light from the first ultraviolet germicidal lamp 16 can be used for irradiation and sterilization through the opening of the protective frame 17.

[0033] The working principle and usage process of this utility model are as follows: In use, firstly, the freezer 1 is moved to a suitable position using the wheel frame 2 and rotating wheels 3. Simultaneously, the freezer 1, the second ultraviolet germicidal lamp 13, the first ultraviolet germicidal lamp 16, and the controller 5 are connected to a power source via wires. The second ultraviolet germicidal lamp 13 and the first ultraviolet germicidal lamp 16 are also connected to the controller 5 via wires. When frozen food or low-temperature items need to be stored, the freezer 1 is opened. Simultaneously, depending on the size of the frozen food or low-temperature items and the required sterilization position, the second rack 8 slides within the first rack 6 via the sliding block 10, and slides within the second rack 8 via the limiting frame 7. This allows the limiting frame 7, the sliding frame 11, and the second ultraviolet germicidal lamp to move within the second rack 8. 13 moves to a suitable sterilization position inside the freezer 1, and simultaneously slides the sliding frame 11 within the limiting frame 7 via the assist plate 12. The movement of the sliding frame 11 drives the second ultraviolet germicidal lamp 13 to move and adjust to a suitable height. After the second ultraviolet germicidal lamp 13 has moved to the desired position, frozen food or low-temperature items are placed inside the freezer 1 for storage. When sterilization is required inside the freezer 1, the controller 5 is activated via a wire to turn on the first ultraviolet germicidal lamp 16 and the second ultraviolet germicidal lamp 13. The first ultraviolet germicidal lamp 16 works in conjunction with the second ultraviolet germicidal lamp 13 to irradiate and sterilize the frozen food or low-temperature items inside the freezer 1, thereby further improving the safety of storing frozen food or low-temperature items in the freezer 1.

[0034] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
