Description

Technical Field

[0001] This utility model relates to the field of quick-freezing cabinet technology, specifically to an ultra-low temperature quick-freezing cabinet with protective functions. Background Technology

[0002] An ultra-low temperature freezer is a device used for freezing. It is used for low-temperature experiments and storage of special materials such as scientific research, medical supplies preservation, biological products, marine products, electronic components, and chemical materials. Quick-frozen foods are processed through rapid freezing at extremely low temperatures, preventing the loss of moisture and juices from the food tissue. Furthermore, at such low temperatures, microorganisms essentially do not multiply, ensuring food safety. Currently, liquid nitrogen freezing is mainly used for low-temperature quick-freezing. However, the condenser in an ultra-low temperature freezer releases heat during the refrigeration process, cooling the high-temperature, high-pressure refrigerant into a liquid. During this process, the condenser surface temperature is extremely low, easily causing moisture in the environment to condense into ice.

[0003] Based on this, after searching, Chinese Patent Publication No. CN220321696U discloses a vertical ultra-low temperature freezer. Under the action of the exhaust fan, the cold air inside the vertical freezer can move upward, pass through five shelves in sequence, and enter the temporary storage box through the air inlet channel. This realizes the uniform flow of cold air between the shelves, minimizes the temperature deviation inside the vertical freezer, and improves the efficiency of the device's low-temperature freezing.

[0004] However, the patent application has shortcomings: when the ultra-low temperature quick-freezing cabinet is used for a long time, ice will easily condense inside the quick-freezing cabinet. As the ice layer thickens, it will occupy the effective internal space of the quick-freezing cabinet. When the operator cleans the inside of the cabinet, the traditional method is to use a shovel to separate the ice, which is physically demanding and can easily damage the inner wall of the cabinet, reducing the practicality of the device.

[0005] To address the aforementioned problems, a low-temperature quick-freezing cabinet with protective functions is proposed. Utility Model Content

[0006] The purpose of this invention is to provide an ultra-low temperature quick-freezing cabinet with protective functions. By using this device, the problem of ice condensation inside the quick-freezing cabinet during long-term use is solved. As the ice layer thickens, it occupies the effective internal space of the quick-freezing cabinet. When the operator cleans the inside of the cabinet, the traditional method requires workers to use shovels to separate the ice, which is physically demanding and can easily damage the inner wall of the cabinet, reducing the practicality of the device.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a protective ultra-low temperature quick-freezing cabinet, comprising an ultra-low temperature quick-freezing cabinet body, a cabinet door rotatably connected to one side of the ultra-low temperature quick-freezing cabinet body, the cabinet door matching the ultra-low temperature quick-freezing cabinet body, a heating component disposed at the upper end of the ultra-low temperature quick-freezing cabinet body, a placement component disposed within the inner cavity of the ultra-low temperature quick-freezing cabinet body, and two sets of the placement component, an installation cavity disposed at the upper end of the ultra-low temperature quick-freezing cabinet body, a vent disposed at the bottom of the installation cavity, the vent, the installation cavity, and the interior of the ultra-low temperature quick-freezing cabinet body being interconnected. The heating assembly includes a mounting frame plate slidably connected to one side of the mounting cavity. A sealing plate is fixedly connected to the front side of the mounting frame plate. A handle block is provided on one side of the sealing plate. A limiting groove is provided on one side of the inner wall of the mounting frame plate, and two sets of the limiting groove are provided. The placement assembly includes a concave shelf plate fixedly connected to the inside of the ultra-low temperature quick-freezing cabinet body. A connecting groove is provided on both sides of the concave shelf plate. A storage groove is provided on one side of the concave shelf plate, and two sets of the storage groove are provided. A slot is provided on one side of each of the two sets of connecting grooves. A placement plate is slidably connected to one side of the concave shelf plate, and connecting blocks are fixedly connected to both sides of the placement plate.

[0008] Preferably, the heating assembly further includes a frame plate slidably connected to one side of the mounting frame plate, and limit blocks are fixedly connected to both sides of the frame plate, the limit blocks matching the limit grooves.

[0009] Preferably, heating tubes are evenly distributed in the middle of the frame plate, and multiple sets of heating tubes are provided. The sealing plate is engaged and connected to the mounting cavity.

[0010] Preferably, the connecting block matches the connecting groove at the corresponding position.

[0011] Preferably, a turntable is rotatably connected to one side of the concave frame plate, and two sets of the turntable are provided, with a first lead screw rotatably connected to the inner cavity of each set of the storage slots.

[0012] Preferably, the top end of the first lead screw is fixedly connected to the bottom of the turntable, and a lifting plate is threadedly connected to the outer circumference of the first lead screw, the lifting plate being slidably connected inside the storage slot.

[0013] Preferably, a movable plate is fixedly connected to one side of the lifting plate, the movable plate is slidably connected to the storage slot, and the movable plate matches the slot.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] 1. This utility model discloses an ultra-low temperature quick-freezing cabinet with protective functions. When using the cabinet body, the user can open the door and place food or other items requiring quick freezing inside. The cabinet body has two sets of placement plates inside, classifying and dividing the internal space. Users can selectively place items on designated placement plates according to their needs, and then close the door. This allows for classified and zoned storage of items, facilitating later retrieval. Multiple placement components can also be evenly installed inside the cabinet body as needed. The cabinet body can withstand long-term freezing... When in use, ice can easily condense inside the freezer. Operators need to use shovels to separate the ice during cleaning and maintenance, which is physically demanding. In this practical application, when cleaning the interior of the ultra-low temperature freezer, the power supply can be turned off first. Then, the heating elements are activated, with multiple heating tubes heating up the interior through the vents. This raises the internal temperature of the freezer, melting the ice and allowing it to fall off, facilitating subsequent cleaning.

[0016] 2. When using the heating element for an extended period, maintenance of the heating tube is required. Pull the handle outwards to pull the mounting frame plate out of the mounting cavity. After removing the sealing plate, manually pull the sealing plate and frame plate in opposite directions to pull the frame plate out from the side of the mounting frame plate. This facilitates subsequent inspection and maintenance of the heating element. When reinstalling the heating element, slide the frame plate back into the inner cavity of the sealing plate to secure the frame plate and mounting frame plate together. Then, slide the sealing plate back into the mounting cavity, ensuring it is tightly locked at the vent opening to seal the mounting cavity. This completes the installation of the heating element. This design allows the heating element to melt the ice on the inner wall of the ultra-low temperature freezer, eliminating the need for workers to shovel ice. The ice automatically falls off due to heat, making cleaning convenient and improving the efficiency of the device.

[0017] 3. After the power to the ultra-low temperature quick-freezing cabinet is cut off and the ice inside the cabinet is melted by the heating element, the user can clean the inside of the cabinet. The cabinet door can be opened, and the inside of the cabinet is in a thawing state. To better clean the internal space of the cabinet, the two sets of placement plates can be removed from the cabinet. Rotate the turntable in the opposite direction, which will drive the first lead screw to rotate in the opposite direction. The first lead screw can drive the lifting plate and the moving plate to move upward, so that the moving plate is separated from the slot. Then the moving plate retracts completely into the storage slot along the storage slot track. The moving plate no longer blocks the connection slot opening. Pull the placement plate outward along the concave shelf until the placement plate is completely away from the concave shelf. The user can use this method to remove both sets of placement plates from the cabinet, and then begin the cleaning work inside the cabinet.

[0018] 4. After the work is completed, the placement plate needs to be reinstalled so that the two sets of connecting blocks are fully pushed into the concave shelf along the connecting groove until the placement plate is back in the center of the concave shelf. Then rotate the two sets of turntables in the forward direction. The forward rotation of the first screw will drive the moving plate to move closer to the slot until the bottom of the moving plate is fully engaged and fixed in the slot. The two sets of moving plates can block the opening of the connecting groove to prevent the two sets of connecting blocks from falling out of the connecting groove and causing the placement plate to fall off. This setting not only achieves spatial separation of the ultra-low temperature quick-freezing cabinet body through multiple sets of placement components, realizing the classification and area storage of items, making it easy to find, but also makes it easy for users to remove the placement plate from the ultra-low temperature quick-freezing cabinet body, facilitating the cleaning of the placement plate and the inside of the ultra-low temperature quick-freezing cabinet body. It is flexible in use and improves the practicality of the device. Attached Figure Description

[0035] In summary, this utility model discloses an ultra-low temperature quick-freezing cabinet with protective functions. The cabinet body 1 uses Haier's BC / BD-142HET model, which is a mature existing technology on the market and will not be elaborated further here. When using the cabinet body 1, the user can open the door 11 and place food or other items that need to be quick-frozen inside. The cabinet body 1 has two sets of placement plates 31 inside, which classify and divide the internal space. The user can selectively classify and place items on the designated placement plates 31 according to their needs. By closing the cabinet door 11, items can be categorized and stored in designated areas within the ultra-low temperature quick-freezing cabinet body 1, facilitating later retrieval. Multiple sets of placement components 3 can also be evenly installed inside the ultra-low temperature quick-freezing cabinet body 1 according to user needs. During prolonged use, ice can easily form inside the cabinet body 1. Cleaning and maintaining the interior requires workers to use shovels to separate the ice, which is physically demanding. In this application, when cleaning the interior of the ultra-low temperature quick-freezing cabinet body 1 is needed, the power supply can be turned off first. Then, the heating components 2 can be activated, and multiple heating elements 26 will heat the interior. The heating element 2 operates by transferring heat through the vent 12 to the interior of the ultra-low temperature quick-freezing cabinet body 1, thereby raising the internal temperature of the ultra-low temperature quick-freezing cabinet body 1. This operation is to melt the ice inside the ultra-low temperature quick-freezing cabinet body 1, allowing the ice to fall off due to heat, facilitating subsequent cleaning work by the user. When the heating element 2 is used for a long time, the heating tube 26 needs maintenance. Pull the handle block 23 outwards, and the handle block 23 will pull the mounting frame plate 21 out of the mounting cavity 13. After the sealing plate 22 is removed, manually pull the sealing plate 22 and the frame plate 25 in opposite directions, thereby pulling the frame plate 25 from the side of the mounting frame plate 21. The heating element 26 can be pulled out from the side for easy maintenance and repair by the user. When the heating element 2 needs to be reinstalled, the frame plate 25 is slid back into the inner cavity of the sealing plate 22, so that the frame plate 25 and the mounting frame plate 21 are fixedly assembled first. Then, the sealing plate 22 is slid back into the installation cavity 13 and the sealing plate 22 is tightly locked and fixed at the vent 12 opening to seal the installation cavity 13, thus completing the installation of the heating element 2. This setting can melt the ice on the inner wall of the ultra-low temperature quick-freezing cabinet body 1 through the heating element 2, avoiding the need for staff to use a shovel to remove the ice. The ice automatically falls off when heated, making cleaning convenient and improving the working efficiency of the device.

[0036] When the power to the ultra-low temperature quick-freezing cabinet body 1 is cut off, and the ice inside the ultra-low temperature quick-freezing cabinet body 1 is melted by the heating component 2, the user can clean the inside of the ultra-low temperature quick-freezing cabinet body 1. The cabinet door 11 can be opened. At this time, the inside of the ultra-low temperature quick-freezing cabinet body 1 is in a thawing state. In order to better clean the internal space of the ultra-low temperature quick-freezing cabinet body 1, the two sets of placement plates 31 can be removed from the ultra-low temperature quick-freezing cabinet body 1. The turntable 33 is rotated in the reverse direction, and the turntable 33 drives the first lead screw 37 to rotate in the reverse direction. When the first lead screw 37 is activated, it drives the lifting plate 36 and the moving plate 35 to move upward, causing the moving plate 35 to disengage from the slot 322. The moving plate 35 then retracts completely into the storage slot 34 along the track, no longer obstructing the opening of the connecting slot 321. The placement plate 31 is then pulled outward along the concave frame plate 32 until it is completely removed from the concave frame plate 32. The user can use this method to remove both sets of placement plates 31 from the ultra-low temperature quick-freezing cabinet body 1, thereby opening the cabinet for ultra-low temperature quick-freezing. After cleaning the interior of the low-temperature quick-freezing cabinet body 1, the placement plate 31 needs to be reinstalled so that the two sets of connecting blocks 311 are fully pushed into the concave shelf plate 32 along the connecting groove 321 until the placement plate 31 is back in the center of the concave shelf plate 32. Then, rotate the two sets of turntables 33 clockwise. The clockwise rotation of the first lead screw 37 will drive the moving plate 35 to move closer to the slot 322 until the bottom of the moving plate 35 is fully engaged and fixed in the slot 322. The two sets of moving plates 35 can then align with the connecting groove. The opening of 321 is blocked to prevent the two sets of connecting blocks 311 from falling out of the connecting groove 321, which would cause the placement plate 31 to fall off. This setting not only achieves spatial separation of the ultra-low temperature quick-freezing cabinet body 1 through multiple sets of placement components 3, realizing the classification and regional storage of items, making it easy to find, but also makes it easy for users to remove the placement plate 31 from the ultra-low temperature quick-freezing cabinet body 1, making it easy for users to clean the placement plate 31 and the inside of the ultra-low temperature quick-freezing cabinet body 1. It is flexible in use and improves the practicality of the device.
