Description

Technical Field

[0001] The utility model relates to the technical field of display cabinets, in particular to an anti-condensation structure, an upper door frame structure and a display cabinet. Background Art

[0002] In the display cabinet industry, especially for those with top-mounted evaporators, condensation has always been a significant issue that needs to be addressed during design and operation. The layout of top-mounted evaporators allows for higher cooling efficiency and more uniform temperature within the cabinet. However, since the upper door frame is closest to the evaporator, this can cause condensation to form on both the inner and outer surfaces of the upper door frame. Especially in high-temperature and high-humidity environments, condensation can flow along the door to the floor or into the display cabinet. This not only affects the comfort of the shopping environment but can also negatively impact the display cabinet's performance, particularly the quality of the products on display.

[0003] In existing display cabinets with top-mounted evaporators, condensation water accumulation is a common problem in the upper door frame design. This makes cleaning and maintenance difficult, thus affecting the normal function and display effect of the display cabinet. Therefore, an effective structural design is needed to prevent the generation and accumulation of condensation water and ensure the normal operation of the display cabinet in high temperature and high humidity environments. Utility Model Content

[0004] The purpose of the present utility model is to provide an anti-condensation structure, an upper door frame structure and a display cabinet. Through the rational design of the heat insulation and the guide groove structure, the heat insulation separates the upper door frame from the evaporator, effectively blocking the direct transfer of cold energy, reducing the temperature drop of the upper door frame, and preventing condensation from occurring on the outer surface of the upper door frame. The condensed water on the heat insulation located on the inner side of the door body is effectively collected and guided into the water receiving box at the bottom of the cabinet through the guide groove.

[0005] The technical solution adopted by the present invention to solve the above technical problems is:

[0006] A condensation prevention structure includes a guide groove and a heat insulation member. The heat insulation member is located at the upper part of the inner side of the door body and is used to separate the evaporator assembly and the upper door frame. The guide groove is located below the heat insulation member and is used to collect and drain condensed water.

[0007] Preferably, the heat insulating member comprises a longitudinally extending baffle, and heat insulating cotton is provided on a side of the baffle close to the door body.

[0008] Preferably, the thermal insulation component has a thermal insulation cavity, and the thermal insulation cavity is a closed structure, or the thermal insulation cavity is a partially open structure.

[0009] Preferably, the heat-insulating cavity is a top-opening structure, and heat-insulating cotton is arranged in the heat-insulating cavity.

[0010] Preferably, a downpipe is provided at the bottom of the guide trough, and the condensed water is discharged through the downpipe.

[0011] Preferably, the guide trough includes plugging heads at both ends, and the downpipe is fixed to the plugging heads.

[0012] Preferably, the guide groove and the thermal insulation component are fixedly connected.

[0013] An upper door frame structure comprises an upper door frame body with a glass groove, wherein the upper door frame body is fixedly connected to the above-mentioned anti-condensation structure.

[0014] A display cabinet includes a cabinet body, a door body is provided on the cabinet body, an upper door frame body is provided on the upper part of the door body, and the inner wall of the cabinet body is fixedly connected to the above-mentioned anti-condensation structure; or the inner wall of the cabinet body is fixedly connected to one of the guide groove and the thermal insulation component, and the other is fixedly connected to the upper door frame body.

[0015] Preferably, when the guide groove is connected to the downpipe and the guide groove is fixed to the upper door frame body, the downpipe is located on the side where the door body and the cabinet body are hingedly connected.

[0016] Compared with the prior art, the advantages of the present invention are:

[0017] 1. The anti-condensation structure of the present invention separates the upper door frame from the evaporator by providing a heat-insulating member, thereby effectively blocking the direct transfer of cold energy, reducing the temperature drop of the upper door frame, preventing condensation on the outer and inner surfaces of the upper door frame, and keeping the door surface dry, thereby improving the user experience of the display cabinet and preventing condensed water from dripping and affecting floor hygiene or flowing into the cabinet and causing damage to the goods; in order to further improve the thermal insulation effect, the thermal insulation member can adopt a closed or partially open structure to form an insulation cavity, and fill the cavity with insulation cotton to further improve the thermal insulation effect.

[0018] 2. The guide groove is set below the insulation. When condensation forms inside the insulation, it can flow smoothly along the guide groove into the downpipe and finally be discharged through the drain hose. The rational design of the guide groove ensures that the condensation water can be effectively collected and discharged, preventing condensation from accumulating inside the display cabinet.

[0027] The technical solution of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0028] Example 1

[0029] A display cabinet, Figure 1-4 As shown, it includes a cabinet body 1, a door body 2 is provided on the cabinet body 1, an upper door frame body 3 is provided on the upper part of the door body 2, and the upper door frame body 3 includes a glass installation groove 31 for installing a glass panel.

[0030] The upper door frame body 3 is fixedly connected to an anti-condensation structure 4, which includes a guide groove 41 and a thermal insulator 42. The thermal insulator 42 is located on the upper inner side of the door body 2 and parallel to the upper door frame body 3. It is used to separate the evaporator assembly 5 from the upper door frame, preventing the direct transfer of cold air to the door frame, thereby reducing the generation of condensation. The guide groove 41 is located below the thermal insulator 42 and effectively collects condensation flowing from the thermal insulator 42 and guides it to the water collection box at the bottom of the display cabinet.

[0031] The thermal insulation component 42 includes a first baffle 421 and a connecting plate 422. The first baffle 421 extends longitudinally, and the connecting plate 422 is fixedly connected to the upper door frame body 3 and the first baffle 421, respectively, so that space is left between the first baffle 421 and the upper door frame body 3. The first baffle 421, the connecting plate 422, and the upper door frame body 3 cooperate to form an insulating cavity 43 with an opening, which separates the evaporator assembly 5 on the upper part of the cabinet 1 and the upper door frame body 3.

[0032] In this embodiment, the connecting plate 422 is arranged at an angle. The upper end of the connecting plate 422 is fixedly connected to the lower end of the upper door frame body 3, and the lower end of the connecting plate 422 is fixedly connected to the first baffle 421. The upper door frame body 3, the connecting plate 422, and the first baffle 421 cooperate to form a heat-insulating cavity 43 with an upper end open above the connecting plate 422. If condensation forms on the inclined connecting plate 422, it can also flow downward into the guide groove 41.

[0033] In another embodiment, the connecting plate 422 extends horizontally.

[0034] In another embodiment, the connecting plate 422 extends horizontally, and one end is fixedly connected to the upper end of the upper door frame body 3, and the other end is fixedly connected to the upper end of the first baffle 421, forming an insulating cavity 43 below the connecting plate 422.

[0035] In this embodiment, the first baffle 421 extends downward to the bottom of the guide groove 41 and is fixedly connected to the middle portion of the bottom of the guide groove 41. The thermal insulation 42 is fixed to the guide groove 41 via clips or screws, ensuring a stable structure. In this embodiment, the upper door frame body 3, the guide groove 41, the first baffle 421, and the connecting plate 422 are integrally formed.

[0036] A downpipe 44 is located at the bottom of the diversion trough 41, through which condensed water is discharged. The diversion trough 41 is designed in a V- or arc-shaped configuration to ensure that condensed water quickly collects at the bottom. Plugs 45 are installed at both ends of the closed diversion trough 41 to prevent water from overflowing. Downpipes 44 are mounted on these plugs 45, through which condensed water flows into the water collection box at the bottom of the cabinet 1.

[0037] When the guide groove 41 is connected to the downpipe 44 and the guide groove 41 is fixed to the door frame body, the downpipe 44 is located on the side where the door body 2 is pivotally connected to the cabinet body 1. The cabinet body 1 and the door body 2 are connected by a hinge. Even if the guide groove 41 is located on the side of the door body 2 and the door body 2 is opened frequently, condensed water can be smoothly discharged through the downpipe 44, preventing water accumulation from affecting the display cabinet's operating environment.
