Description

Technical Field

[0001] This utility model relates to the technical field of cabinet ventilation door structure, and in particular to a cabinet ventilation door structure. Background Technology

[0002] In both home and commercial settings, the need for ventilation and dehumidification in cabinets such as shoe cabinets and kitchen cabinets is ever-present. However, these cabinets often face numerous problems during use. For example, shoe cabinets accumulate a lot of odor due to shoes being stored inside for extended periods, and bacteria easily grow in the damp environment. Kitchen cabinets, when storing food and tableware, often suffer from excessive moisture due to poor ventilation, leading to moldy tableware, spoiled food, and reduced practicality of the cabinet and the lifespan of the stored items. Existing cabinets generally employ natural ventilation designs, which involve creating simple ventilation holes in the cabinet doors or side panels. However, such structures rely solely on natural air convection, resulting in extremely low ventilation efficiency in enclosed spaces or environments with poor air circulation, making it difficult to quickly remove moisture and odors. Some cabinets are equipped with independent mechanical ventilation devices, such as adding fans inside the cabinet. However, such solutions require additional internal cabinet space, and the fans are separate from the cabinet structure, making installation inconvenient and maintenance costs high. Therefore, these existing methods cannot adequately meet people's needs for efficient odor removal and dehumidification in cabinets, and there is an urgent need for an innovative ventilation door structure to optimize the ventilation and dehumidification performance of cabinets. Utility Model Content

[0003] The purpose of this utility model is to provide a cabinet ventilation door structure to achieve circulating ventilation inside the shoe cabinet.

[0004] In accordance with the above objectives, this utility model provides a cabinet ventilation door structure, including a door panel for installation on a cabinet. Each door panel has an air inlet at its bottom and an air outlet at its top. Several inclined guide plates are provided at both the air inlet and outlet, forming an airflow channel between adjacent guide plates. Filter components are provided on the back side of each guide plate corresponding to the air inlet and outlet. A fan is detachably installed at the air outlet between the guide plates and the filter components.

[0005] Furthermore, the guide plate is inclined at 30°-60° along the thickness direction of the door panel.

[0006] Furthermore, an odor sensor is provided on the inner side of the door panel, and the odor sensor is electrically connected to the fan via a controller.

[0007] Furthermore, a first filter assembly is provided at the air inlet. The first filter assembly includes a first pressing frame and a first filter layer. The first pressing frame is detachably connected to the door panel via a magnetic attraction structure. The magnetic attraction structure includes a permanent magnet disposed on the door panel and an iron sheet on the edge of the first pressing frame.

[0008] Furthermore, a second filter assembly is provided at the air outlet. The second filter assembly includes a second pressing frame and a second filter layer. The fan is fixedly installed on the door panel by a mounting frame, and the second pressing frame is sleeved on the back side of the mounting frame.

[0009] Furthermore, the first filter layer and the second filter layer are filter screens or filter cotton.

[0010] Furthermore, the filter screen is made of a metal material.

[0011] Furthermore, several heating wires are installed at the air inlet at the bottom of the door panel.

[0012] Furthermore, an elastic sealing strip is provided on the inner wall of the second clamping frame.

[0013] Furthermore, the door panel is equipped with latches for connecting to the cabinet.

[0014] The technical solution of this utility model, by setting an air inlet at the bottom of the door panel and an air outlet at the top, combined with the directional airflow channel formed by the inclined guide plate, can form efficient air convection by utilizing the thermal pressure effect and the active air supply of the fan, which significantly improves the efficiency of moisture and odor removal compared to traditional natural ventilation; the filter components on the back of the air inlet and air outlet can effectively intercept dust and other pollutants, ensuring a clean environment inside the cabinet, while preventing dust accumulation on the fan; the fan structure that can be detachably installed at the air outlet of the door panel not only avoids the defects of independent fans occupying internal cabinet space, but also facilitates later maintenance and replacement. At the same time, it is integrated with the guide plate and filter components into the door panel structure, realizing the integrated design of ventilation, filtration and power components, effectively solving the problems of low ventilation efficiency, inconvenient maintenance and large space occupation in the prior art.

Its structure includes a door panel 1 for installation on the cabinet, an air inlet 2 at the bottom of the door panel 1, and an air outlet 3 at the top of the door panel 1. Both the air inlet 2 and the air outlet 3 are provided with several inclined guide plates 4, which are inclined at 30°-60° along the thickness direction of the door panel 1 and are equidistantly arranged along the height direction of the door panel 1. An airflow channel is formed between adjacent guide plates 4. Filter components are provided on the back side of the guide plates 4 at the air inlet 2 and air outlet 3 on the door panel 1. Specifically, a first filter component is provided at the air inlet 2. The first filter component includes a first pressing frame 6 and a first filter layer 5. The edge of the first pressing frame 6 presses and fixes the first filter layer 5 at the air inlet 2. The first pressing frame 6 is detachably connected to the door panel 1 through a magnetic attraction structure. The magnetic attraction structure includes a permanent magnet 13 set on the door panel 1 and an iron sheet on the edge of the first pressing frame 6. The iron sheet is welded to the first pressing frame 6. A second filter assembly is provided at the air outlet 3. The second filter assembly includes a second pressing frame 9 and a second filter layer 14. The fan 11 is fixedly installed on the door panel 1 through the mounting frame 10. The second pressing frame 9 is sleeved on the back side of the mounting frame 10. The inner wall of the second pressing frame 9 presses and fixes the second filter layer 14 to the mounting frame 10. In order to enhance the sealing effect between the second pressing frame 9 and the mounting frame 10, as well as the pressing effect on the second filter layer 14, an elastic sealing strip 12 is provided on the inner wall of the second pressing frame 9. The elastic sealing strip 12 forms an interference fit with the mounting frame when the second pressing frame 9 is installed.

[0026] In this embodiment, both the first filter layer 5 and the second filter layer 14 are filter cotton. After the first filter layer 5 and the second filter layer 14 are compressed and fixed, the excess material at the edges needs to be trimmed. The first filter layer is set to prevent dust and other foreign objects from entering the cabinet, and the second filter layer is set to prevent dust from accumulating on the surface of the fan, thus reducing the number of times the fan needs to be disassembled and cleaned.

[0027] A fan 11 is detachably installed on the door panel 1 at the air outlet 3 via the mounting frame 10. The fan 11 is installed between the guide plate 4 and the filter assembly. Multiple fans 11 are arranged in a linear array. Multiple fans 11 are fixedly installed in the mounting frame 10 by screws. The mounting frame 10 is fixedly installed on the door panel 1 by screws.

[0028] An odor sensor is installed on the inside of the door panel 1. The odor sensor is electrically connected to the fan 11 through the controller. When an odor is detected inside the cabinet, it sends a signal to the controller, which then controls the fan 11 to start. The number of fans 11 that can be turned on can be controlled according to the odor concentration.

[0029] Example 2

[0030] The difference between this embodiment and embodiment 1 is that: the first filter layer 5 is a filter screen made of metal material, and the filter screen is fixed to the first clamping frame 6 by screws or welding. Several heating wires 8 are installed at the air inlet 2 of the door panel 1. The heating wires 8 are fixed as a whole by the frame 7. The heating wires 8 are connected to the power supply through the controller. Correspondingly, a humidity sensor electrically connected to the controller is set on the inner side of the door panel 1 or the inner side of the cabinet. The heating wires 8 are set to heat the air inlet 2 to achieve rapid drying inside the cabinet.

[0031] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it.
