Description

Technical Field

[0001] This utility model relates to the field of ventilation panel technology, specifically a ventilation panel. Background Technology

[0002] For high-power refrigeration equipment such as ultra-low temperature freezers, the heat generated inside the compressor compartment is enormous, requiring high ventilation and heat dissipation efficiency. Therefore, ventilation openings are installed on the refrigerator compressor compartment for heat dissipation. Typically, a ventilation plate is also installed at the ventilation opening, with densely packed ventilation holes for aesthetic purposes, dust prevention, and ventilation. However, over time, a small amount of dust can enter the refrigerator compressor compartment, and a large amount of dust can adhere to the ventilation plate.

[0003] The ventilation panel is fixed to the cabinet at its four corners using bolts. During disassembly, each bolt must be turned one by one to completely separate the ventilation panel from the cabinet. However, during the disassembly of the last three corners, the ventilation panel will repeatedly shake or shift significantly at the vent. Each movement generates airflow that causes dust to fall from the mesh cover. The greater the movement, the more dust falls. Some ventilation panels are designed to open and close by rotating, but cannot be directly disassembled, causing dust to spread outward from the ventilation panel. This dust can spread into the refrigerator compressor compartment, interfering with maintenance. Utility Model Content

[0004] The purpose of this invention is to provide a ventilation panel to solve the problems raised in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a ventilation panel, comprising: The outer frame is used for installation at the ventilation opening in the refrigerator compressor compartment; The airflow from the ventilation openings passes through the mesh cover. The inner frame and the mesh cover are located on the inner frame; The opening and closing mechanism is used to adjust the angle between the inner frame and the outer frame to open and close the inner frame; The dustproof panel is inserted between the inner and outer frames when the inner frame is opened to a set angle to isolate dust on the outer frame.

[0006] Furthermore, the mesh cover is a mesh structure woven from cylindrical steel wires.

[0007] Furthermore, the opening and closing mechanism includes two rotating positioning blocks and two positioning seats. The two rotating positioning blocks are symmetrically fixed on the top two sides of the inner frame. The two positioning seats are symmetrically arranged on the top of the outer frame and distributed on both sides of the ventilation opening. The positioning seats are provided with a connecting shaft, and the connecting shaft is provided with a communicating opening and a rotating arc groove. The rotating positioning blocks enter and exit the rotating arc groove through the opening.

[0008] Furthermore, the opening and closing mechanism also includes a spring, two linear positioning components, and two positioning seats. The linear positioning component includes a linear positioning rod and a side lug. One end of the linear positioning rod extends into the positioning seat and is connected to the positioning seat via a spring. The other end of the linear positioning rod is symmetrically provided with inclined surfaces a and b. The positioning seat is symmetrically provided with side lugs at the end near inclined surface a. The bottom of the inner frame is symmetrically provided with positioning holes.

[0014] 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.

[0015] See Figures 1-10 .

[0016] This utility model provides a ventilation plate, including an outer frame 1, for installation at the ventilation opening of the refrigerator compressor compartment; The airflow from the inlet and outlet vents passes through the mesh cover 2; Inner frame 3, mesh cover 2 is located on inner frame 3; The opening and closing mechanism is used to adjust the angle between the inner frame 3 and the outer frame 1 to open and close the inner frame 3. Dustproof plate 4, when the inner frame 3 is opened to a set angle, is inserted between the inner frame 3 and the outer frame 1 to isolate dust on the outer frame 1.

[0017] It should be noted that, during use, human movement should be minimized to reduce the disturbance of airflow and thus reduce the spread of dust on the ventilation panel. When opening, first rotate the inner frame upward at a small angle, then attach the dustproof panel to the bottom of the inner frame to prevent dust from spreading into the refrigerator compressor compartment during the opening process. Continue rotating the inner frame until it is in place, then pull it outward to separate the inner frame from the outer frame. No manual operation of the opening and closing mechanism is required; the inner frame will automatically separate from the outer frame once it is fully opened. This reduces human movement and improves ease of use.

[0018] The opening and closing mechanism includes two rotating positioning blocks 50 and two positioning seats 51. The two rotating positioning blocks 50 are symmetrically fixed on the top two sides of the inner frame 3. The two positioning seats 51 are symmetrically arranged on the top of the outer frame 1 and distributed on both sides of the ventilation opening. The positioning seat 51 is provided with a connecting shaft 52, and the connecting shaft 52 is provided with a communicating opening 53 and a rotating arc groove 54. The rotating positioning blocks 50 enter and exit the rotating arc groove 54 through the opening 53.

[0019] Use bolts to install the outer frame 1 at the ventilation opening of the refrigerator compressor compartment. The mesh cover 2 is fixed to the inner frame 3, and the inner frame 3 is attached to the outer frame 1. At this time, the inner frame 3 is closed, completing the installation. To open the outer frame 1, pull it outwards and rotate the linear positioning component 56 90 degrees. This allows the side ear 561 to disengage from the first side ear groove 60. The linear positioning rod 560 then rotates 90 degrees, and the side ear 561 enters the second side ear groove 61. Then, release the linear positioning component 56. At this point, the spring 55 is in a balanced state. The balanced state means that the spring 55 is neither stretched nor compressed. The two bottom linear positioning parts 56 operate in the same way to unlock the bottom of the inner frame 3. Hold the bottom of the inner frame 3 and apply force outward to drive the inner frame 3 to rotate around the connecting shaft 52. When the angle between the inner frame 3 and the outer frame 1 is 15-20 degrees, insert the dustproof plate 4 between the inner frame 3 and the outer frame 1, and the dustproof plate 4 is in contact with the inner frame 3 and the mesh cover 2. Because the area and shape of the dustproof plate 4 are adapted to the mesh cover 2, the dustproof net can cover the mesh cover 2.

[0020] In one embodiment, the opening and closing mechanism further includes a spring 55, two linear positioning members 56, and two positioning seats 57. The linear positioning member 56 includes a linear positioning rod 560 and a side ear 561. One end of the linear positioning rod 560 extends into the positioning seat 57 and is connected to the positioning seat 57 via the spring 55. The other end of the linear positioning rod 560 is symmetrically provided with inclined surfaces a and b. The positioning seat 57 is symmetrically provided with side ears 561 at the end near the inclined surface a. The bottom of the inner frame 3 is symmetrically provided with positioning holes 58. When the linear positioning member 56 is inserted into the positioning hole 58, the inclined surface a passes through the positioning hole 58. The bottom of the inner frame 3 is provided with a first side ear groove 60 and a second side ear groove 61, which pass through the inner frame 3. The position of the side ear 561 is restricted by the first side ear groove 60 or the second side ear groove 61 to control the direction of the inclined surface a.

[0021] With this design, referring to 4-7, the positioning seat 2 57 is provided with a linear positioning groove 59 for accommodating the linear positioning component 56. After the dustproof plate 4 is inserted, the dustproof plate 4 and the inner frame 3 are held at the same time and continue to rotate outward. The inner frame 3 applies a pushing force to the linear positioning rod 560 through the inclined surface a. The linear positioning rod 560 moves back into the linear positioning groove 59, and the spring 55 is squeezed until the inclined surface a is completely separated from the positioning hole 58 of the linear positioning rod 560. Then, the inner frame 3 continues to drive the connecting shaft 52 and the rotating positioning block 50 to rotate synchronously. The rotating positioning block 50 continues to rotate along the positioning arc groove. The spring 55 extends and resets, driving the linear positioning rod 560 to reset. When the angle between the inner frame 3 and the outer frame 1 is 90-100 degrees, the rotating positioning block 50 disengages from the positioning arc groove. At this time, pulling the inner frame 3 outward causes the rotating positioning block 50 to disengage from the opening 53 of the positioning shaft, thereby removing the inner frame 3 and the mesh cover 2 for maintenance of the refrigerator compressor compartment. Rotating the inner frame 3 slightly with the connecting shaft 52 as the fulcrum is more stable than directly supporting the inner frame 3 with both hands to disengage it from the four positioning points, minimizing the interference of human movement on airflow and reducing the probability of dust diffusion on the ventilation plate. After opening, the dust isolation plate 4 is inserted in time to isolate the ventilation opening and the mesh cover 2. Dust on the mesh cover 2 will fall directly onto the dust isolation plate 4, preventing dust from falling and spreading during subsequent disassembly. Finally, the mesh cover 2 is removed for centralized cleaning in a place away from the refrigerator compressor compartment.

[0022] When installing the inner frame 3, hold the inner frame 3 horizontally, align the rotating positioning block 50 with the opening 53 of the insertion connecting shaft 52, and then rotate the inner frame 3 downwards, so that the inner frame 3 drives the rotating positioning block 50 into the positioning arc groove through the connecting shaft 52. Continue to rotate the inner frame 3 downwards. When the inner frame 3 contacts the inclined surface b, continue to rotate the inner frame 3 downwards. The inner frame 3 pushes the linear positioning rod 560 to move backwards into the linear positioning groove 59 through the inclined surface b. When the inner frame 3 is reset, the linear positioning rod 560 is aligned with the positioning hole 58 again. The spring 55 itself drives the linear positioning rod 560 to reset and insert into the positioning hole 58. Pull it outwards again and rotate the linear positioning part 56 in the opposite direction by 90 degrees, so that the side ear 561 is inserted back into the side ear groove 60 and reset, completing the installation.

[0023] In one embodiment, the mesh cover 2 is a cylindrical steel wire woven mesh structure.

[0024] This design, for reference Figure 1-4 The mesh cover 2 adopts a mesh structure woven from cylindrical steel wires. Its advantages are a large ventilation area and relatively low wind resistance when the wind passes through the mesh structure because it impacts the cylindrical steel wires.

[0025] In one embodiment, the inner frame 3 is provided with fixing holes for threading nylon buckles, and both the inner frame 3 and the outer frame 1 are made of sheet metal.

[0026] This design uses nylon buckles to pass through fixing holes (not shown in the figure) to fix the mesh cover 2 to the inner frame 3, improving the rigidity of the entire structure; when the mesh cover 2 is damaged, it can be replaced separately, reducing the cost of use.

[0027] In one embodiment, the dustproof plate 4 has an adhesive layer on one or both sides, which allows dust to be adsorbed onto the dustproof plate 4.

[0028] With this design, the falling dust will fall directly onto the dustproof plate 4 and be fixed there, preventing air disturbances caused by human hand movement from further spreading dust on the inner frame 3.

[0029] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.

[0030] It should be noted that if the utility model embodiment involves directional indicators (such as up and down), the directional indicators are only used to explain the relative positional relationship and movement of the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.

[0031] Furthermore, the meaning of "and / or" throughout the text includes three parallel solutions. Taking "A and / or B" as an example, it includes solution A, solution B, or a solution that simultaneously satisfies A and B. Additionally, if the utility model embodiments involve descriptions such as "first," "second," etc., these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of indicated technical features. Therefore, features defined with "first" or "second" can explicitly or implicitly include at least one of those features. Furthermore, "multiple" refers to two or more.

[0032] Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of a person skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection of the utility model.
