Description

Technical Field

[0001] The utility model relates to the technical field of refrigeration equipment, and particularly relates to a horizontal freezer. Background Art

[0002] A horizontal freezer is a common refrigeration equipment, which is widely used in commercial and household environments for storing and preserving food, beverages and other items. According to different uses and functions, horizontal freezers can be divided into various types, such as commercial horizontal freezers, household horizontal freezers, supermarket display cabinets, etc. Among them, commercial horizontal freezers usually have a larger storage space and stronger refrigeration capacity, and are suitable for commercial places that need to store and preserve a large number of items; household horizontal freezers pay more attention to energy conservation, quietness and ease of use, and are suitable for household use. Horizontal freezers usually adopt a horizontal structure design, that is, the cabinet body is placed horizontally. Compared with vertical freezers, it occupies a relatively large floor area, but has a more spacious storage space, which is convenient for storing large items. The inside of a horizontal freezer is usually equipped with multiple layers of shelves or drawers, which is convenient for users to classify and store different kinds of items.

[0003] However, when the sliding door on the existing horizontal freezer is manually closed, it may not be fully closed due to insufficient force and accidentally open, causing the temperature inside the horizontal freezer to rise. This will not only affect the preservation effect of the items in the horizontal freezer, but also increase the refrigeration burden of the horizontal freezer, resulting in increased energy consumption and reduced energy efficiency. Summary of the Utility Model

[0004] Based on this, in order to solve the problem that when the sliding door on the existing horizontal freezer is manually closed, it may not be fully closed due to insufficient force and accidentally open, causing the temperature inside the horizontal freezer to rise, the purpose of the utility model is to provide a horizontal freezer, and its specific technical solution is as follows:

[0005] A horizontal freezer includes a gravity sliding door and a freezer cabinet body. A plurality of rollers are arranged below the gravity sliding door; the gravity sliding door is slidably connected with the freezer cabinet body, and a plurality of positioning grooves are arranged at the top of the freezer cabinet body. The top of the freezer cabinet body is inclined upward from the direction close to each positioning groove to the direction away from each positioning groove. When the gravity sliding door is in a closed state, each roller is respectively located in the corresponding positioning groove.

[0006] Further, the inclination angle of the top of the freezer cabinet body inclined upward from the direction close to each positioning groove to the direction away from each positioning groove is set to 1.5°-3.5°.

[0007] Further, the gravity sliding door includes a door body and a door seal. The door seal is fixedly connected to the side of the door body close to the gravity sliding door, and each roller is arranged on the door body and rotatably connected with the door body.

[0008] Furthermore, the assembly height of each roller is 1.5 mm - 4 mm higher than the assembly height of the door seal.

[0009] Furthermore, the depth of each positioning groove is 1 mm - 2.5 mm deeper than the height difference between each roller and the door seal.

[0010] Furthermore, a limit block is provided on the surface of the front end of the gravity sliding door close to the refrigerator cabinet body.

[0011] Furthermore, when the gravity sliding door is pushed upward to make each roller leave the corresponding positioning groove, the distance between the door seal and the top of the refrigerator cabinet body is 1.5 mm - 4 mm.

[0012] Furthermore, four rollers are provided below the gravity sliding door, and four positioning grooves are provided above the refrigerator cabinet body, and each roller and each positioning groove are arranged correspondingly.

[0013] Furthermore, the rollers are arranged in a rectangular or square pattern.

[0014] Furthermore, each positioning groove is provided as an arc-shaped groove.

[0015] Compared with the prior art, the beneficial effects of the present utility model are as follows: In the horizontal refrigerator of the present utility model, by providing rollers and positioning grooves, since the top of the refrigerator cabinet body is inclined, the gravity sliding door will naturally slide downward under the action of gravity, making the closing process of the gravity sliding door smoother. When the gravity sliding door is in the closed state, each roller is respectively located in the corresponding positioning groove, and each roller should correspond to a positioning groove. When the door slides down to the closed position, each roller can accurately enter the corresponding groove to achieve stable positioning and support. Through the cooperation of the rollers and the positioning grooves, the function of these positioning grooves is to provide a stable support point for the rollers when the gravity sliding door slides down to a specific position. When the gravity sliding door is closed, the rollers will automatically slide into the corresponding positioning grooves, and they will engage with each other to limit the further sliding of the door, achieving automatic positioning. The horizontal refrigerator of the present utility model effectively avoids the situation that the sliding door is not fully closed or misaligned due to improper human operation, ensures that the gravity sliding door can accurately stay at the predetermined position when closed, improves the sealing performance of the refrigerator, reduces the leakage of cold air, thereby maintaining the low-temperature environment inside the refrigerator and extending the fresh-keeping period of food.

[0027] Such as Figures 1 - 4As shown in the figure, a horizontal freezer in an embodiment of the present utility model includes a gravity sliding door 1 and a freezer cabinet body 3. A plurality of rollers 2 are arranged below the gravity sliding door 1; the gravity sliding door 1 is slidably connected to the freezer cabinet body 3. A plurality of positioning grooves 31 are arranged at the top of the freezer cabinet body 3. When the gravity sliding door 1 is in the closed state, each roller 2 is respectively located in the corresponding positioning groove 31. Each roller 2 should correspond to a positioning groove 31. When the door slides down to the closed position, each roller 2 can accurately enter the corresponding groove to achieve stable positioning and support. Through the cooperation of the roller 2 and the positioning groove 31, the function of these positioning grooves 31 is to provide a stable support point for the roller 2 when the gravity sliding door 1 slides down to a specific position. When the gravity sliding door 1 is closed, the roller 2 will automatically slide into the corresponding positioning groove 31, and they will engage with each other to limit the further downward sliding of the door, realizing automatic positioning, ensuring that the gravity sliding door 1 can accurately stay at the predetermined position when closed, improving the sealing performance of the freezer, reducing the leakage of cold air, thereby maintaining the low-temperature environment inside the freezer and extending the freshness preservation period of food.

[0028] As a preferred embodiment of the present utility model, it may further have the following additional technical features: The top of the freezer cabinet body 3 is inclined upward from the direction close to each positioning groove 31 to the direction away from each positioning groove 31. When the gravity sliding door 1 is closed, due to the inclination of the top of the freezer cabinet body 3, the gravity sliding door 1 will naturally slide downward under the action of gravity, making the closing process of the gravity sliding door 1 smoother, effectively avoiding the situation that the sliding door is not fully closed or misaligned due to improper manual operation. In this embodiment, the inclination angle of the top of the freezer cabinet body 3 inclined upward from the direction close to each positioning groove 31 to the direction away from each positioning groove 31 is set to 1.5° - 3.5°, so that the gravity sliding door 1 can more naturally fit the inclined surface of the freezer cabinet body 3 when closed, thereby enhancing the sealing performance between the gravity sliding door 1 and the freezer cabinet body 3. The inclination angle within this range can ensure that the gravity sliding door 1 is in close contact with the freezer cabinet body 3, and will not cause difficulty in opening the sliding door or unstable closing due to too large an angle. Users can easily push the gravity sliding door 1 to the closed position without applying excessive force.

[0029] As a preferred embodiment of the present utility model, it may further have the following additional technical features: The gravity sliding door 1 includes a door body 11 and a door seal 12. The door seal 12 is fixedly connected to one side of the door body 11 close to the gravity sliding door 1. Each roller 2 is arranged on the door body 11 and rotatably connected to the door body 11. When the gravity sliding door 1 is in the closed state, the gravity sliding door 1 presses down, and the door seal 12 closely adheres to the inclined surface at the top of the freezer, playing a sealing role. The tight fit ensures the effective isolation between the inside and outside of the freezer, prevents the leakage of cold air, enhances the sealing performance of the freezer, and also improves its heat preservation effect. A freezer with good sealing can more effectively maintain the low-temperature environment inside, reduce the running time and energy consumption of the refrigeration system, thereby extending the freshness period of food and reducing the operating cost.

[0030] As a preferred embodiment of the present utility model, it may further have the following additional technical features: The assembly height of each roller 2 is 1.5 mm - 4 mm higher than the assembly height of the door seal 12. When the gravity sliding door 1 is closed, the roller 2 first contacts the inclined surface at the top of the freezer cabinet body 3, and as the gravity sliding door 1 is further pressed down, the door seal 12 gradually contacts and compresses the inclined surface. Since the assembly height of the roller 2 is slightly higher than that of the door seal 12, it ensures that the door seal 12 can receive sufficient pressure when contacting the inclined surface, thereby achieving a tighter fit and better sealing effect; at the same time, within this height difference range, the gravity sliding door 1 can adapt to different usage conditions and requirements. For example, in an environment with large temperature changes, the inclined surface at the top of the freezer cabinet body 3 may undergo slight deformation due to thermal expansion and contraction. By setting a reasonable height range, it can ensure that the roller 2 and the door seal 12 can maintain stable contact and sealing effect under different conditions.

[0031] As a preferred embodiment of the present utility model, it may further have the following additional technical features: The depth of each positioning groove 31 is 1 mm - 2.5 mm deeper than the height difference between each roller 2 and the door seal 12, ensuring that the roller 2 can smoothly slide in and stay stably, effectively preventing the gravity sliding door 1 from shaking or shifting during the closing or opening process. The cooperation between the roller 2 and the positioning groove 31 can ensure that the sliding door can accurately stay at the predetermined position when closed, avoiding affecting the sealing performance due to position deviation.

[0032] As a preferred embodiment of the present utility model, it may further have the following additional technical features: A limit block 4 is provided on the front surface of the gravity sliding door 1 close to the freezer cabinet body 3. When the gravity sliding door 1 falls naturally, the limit block 4 can abut against the inner wall of the freezer, thereby restricting the movement of the gravity sliding door 1 and preventing the gravity sliding door 1 from sliding down too fast, causing the roller 2 to rush past the positioning groove 31 and resulting in the gravity sliding door 1 falling off the freezer cabinet body 3.

[0033] As a preferred embodiment of the present utility model, it may further have the following additional technical features: When the gravity sliding door 1 is pushed upward until each roller 2 leaves the corresponding positioning groove 31, the roller 2 moves out of the positioning groove 31 and jacks up the entire door body 11, and the distance between the door seal 12 and the top of the freezer cabinet body 3 is 1.5 mm - 4 mm.

[0034] As a preferred embodiment of the present utility model, it may further have the following additional technical features: Four rollers 2 are provided below the gravity sliding door 1, and four positioning grooves 31 are provided above the freezer cabinet body 3. Each roller 2 and each positioning groove 31 are correspondingly arranged, which can better disperse the weight of the door, reduce the single-point force, thereby enhancing the stability of the door, and helping to prevent the door from shaking or shifting during the opening or closing process. In this embodiment, the four rollers 2 are evenly distributed on the bottom edge of the door body 11, arranged in a rectangular or square shape, ensuring that the gravity sliding door 1 is evenly stressed during the sliding process and reducing the possibility of skewing or shaking. In addition, in other embodiments, the number and size of the rollers 2 and the positioning grooves 31 can be designed differently according to different needs.

[0035] As a preferred embodiment of the present utility model, it may further have the following additional technical features: Each positioning groove 31 is provided as an arc-shaped groove, so that the roller 2 can enter and stay in the positioning groove 31 more smoothly during the sliding process. Compared with a straight groove, the curved shape of the arc-shaped groove provides a natural guiding path for the roller 2, reducing the risk of the roller 2 deviating from the groove due to improper operation or external interference.

[0036] The working principle of the horizontal freezer in this embodiment is as follows: The gravity sliding door 1 is slidably connected to the top of the freezer cabinet body 3 through the rollers 2 below. When the gravity sliding door 1 is in the closed state, each roller 2 accurately enters the corresponding positioning groove 31 and engages with each other, thereby restricting the further downward movement of the door and realizing automatic positioning, achieving stable positioning and support.

[0037] The structural design of the horizontal freezer in this embodiment is reasonable and easy to use. For other devices with similar usage requirements, this structure can also be adopted. In this embodiment, the horizontal freezer effectively avoids the situation where the sliding door is not fully closed or misaligned due to improper human operation, ensures that the gravity sliding door 1 can accurately stay at the predetermined position when closed, improves the sealing performance of the freezer, reduces the leakage of cold air, thereby maintaining the low-temperature environment inside the freezer and extending the fresh-keeping period of food.

[0039] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction between these technical feature combinations, they should be considered to be within the scope described in this specification.
