DETAILED DESCRIPTION

[0024] The following will describe the implementation methods of the present application in detail with the help of accompanying drawings and examples, so that the implementation process of how the present application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0025] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0026] The specific problem addressed by this specific embodiment is that the existing exhaust structure of refrigeration units lacks dust-proof components, which often leads to dust accumulation inside the exhaust port during the operation of the exhaust structure. Due to its closed state, it is not convenient to clean it from time to time, which can easily cause the exhaust port to gradually decrease in functionality or even lose functionality, affecting the use effect of the device. Based on this situation, the solution proposed by this embodiment is to set a dust-proof component at the front end of the exhaust structure, and to intermittently clean the dust accumulated in the dust-proof component during operation, thereby reducing the amount of dust accumulation. On the one hand, it avoids the loss of the dust-proof function of the dust-proof component, and on the other hand, it avoids excessive dust accumulation and overflowing backward with the airflow, thereby losing the dust-proof effect. Based on this idea, this embodiment specifically describes an exhaust structure of a refrigeration unit, such as Figure 1-Figure 4As shown, a dustproof frame 1 inserted into the refrigerator and an exhaust fan 2 installed on the dustproof frame 1 are provided, a dustproof filter element 3 and a filter screen 4 installed on one end of the dustproof filter element 3 are provided inside the dustproof frame 1, and the filter screen 4 is installed when the dustproof filter element 3 is fully loaded and cannot be used further, but cannot be replaced in the current usage scenario, the filter screen 4 arranged on the upper end of the dustproof filter element 3 can delay the loss of the wind function, and a dust collecting box 5 is detachably provided at the lower end of the installation position of the dustproof filter element 3 and the dustproof frame 1, thereby providing a collection channel for the dust scraped from the dustproof filter element 3, preventing it from being scattered inside the dustproof frame 1 and continuing to adhere to the dustproof filter element 3 with the airflow, thereby causing further cleaning problems.

[0027] A mounting bin 6 is provided at one end of the dustproof frame 1, and a cleaning channel 7 for cleaning the dust filter element 3 is provided inside the mounting bin 6 and is connected to the inside of the dustproof frame 1. A cleaning piece 8 is provided in the cleaning channel 7, and a driver is provided inside the mounting bin 6 for starting the reciprocating motion of the cleaning piece 8 on the dust filter element 3, and using its own structural setting to scrape off the dust attached to the dust filter element 3, thereby enhancing the service life of the dust filter element 3. The dust filter element 3 in this embodiment plays the role of filtering dust in the airflow. In the prior art, products that can achieve this function have been popularized and available, and therefore, it can achieve its function in this embodiment and be adapted to the size of the dustproof frame 1 in actual production.

[0028] The cleaning component 8 includes a connecting block 81 connected to the upper and lower frame plates of the dustproof frame 1, and a slide 10 is arranged on the upper and lower frame plates of the dustproof frame 1. A screw is arranged inside the slide 10 and the screw is driven to rotate by a driver. The connecting block 81 is threadedly connected to the screw, so that the screw is prompted to reciprocate in the slide 10 based on the forward or reverse rotation of the screw. A cleaning plate 82 is arranged between the two connecting blocks 81 and is shaped in accordance with the dust filter element 3. The left and right structures of the cleaning plate 82 are provided with guides for downwardly guiding the dust accumulated on the dust filter element 3. The cleaning plate 82 is driven by the connecting block 81 to reciprocate in the slide 10, and its structure shape is arranged to be consistent with the dust filter element 3 to achieve the effect of removing the dust accumulated on the structure of the dust filter element 3.

[0029] The dust filter 3 is arranged in a wave shape, and a guide rod 9 for positioning and installing is installed on the upper end of the dust filter 3. The guide rod 9 is pushed inward or outward along the guide groove 13 opened on the side wall of the dust frame 1 to establish a replacement path for the dust filter 4. The opening depth of the guide groove 13 is less than the opening depth of the cleaning channel 7. The filter 4 is installed on the guide rod 9 and connected to the upper plate of the dust frame 1. The filter 4 is arranged in a plate shape and has a plurality of air holes opened thereon. The air overflow degree generated by the air holes is greater than the air overflow degree of the dust filter 3.

[0030] The dust collecting box 5 includes a box body 51 and a dust guide plate 52 installed on the box body 51. In order to be able to detach it from the dustproof frame 1 and clean the dust in the box body 51 after a period of time based on the amount of dust accumulated inside the box body 51, in the present embodiment, a T-shaped boss 53 for connecting with the dustproof frame 1 is specifically installed on the box body 51, and a sliding inner groove is adapted to be opened on the dustproof frame 1, thereby forming the detachability of the box body 51 in the dustproof frame 1.

[0031] The front end of the filter 4 is provided with a panel 11 connected to the dustproof frame 1, and a strip-shaped air duct for forming air intake into the dustproof frame 1 is provided on the panel 11. There is a distance between the filter 4 and the panel 11, and a dust inlet 12 is provided at the distance for accumulated dust to be scraped off and accumulated in the dust box 5. The opening width of the dust inlet 12 is greater than the setting width of the cleaning plate 82, and the dust guide plate 52 is installed in an inclined shape at the setting position of the dust inlet 12 and extends inside the box body 51, so that dust can move into the dust box 5 along the dust guide plate 52 to avoid blocking the dust inlet 12.

[0032] The control method of the present invention is automatic control through a controller. The control circuit of the controller can be realized by simple programming by technicians in this field. The provision of power is also common knowledge in this field. The present invention is mainly used to protect mechanical devices, so the present invention will no longer explain the control method and circuit connection in detail.

[0033] It should be noted that, in this article, the terms "comprises", "includes" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or apparatus that includes a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or apparatus.

[0034] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
