Description

Technical Field

[0001] The utility model relates to the technical field of air conditioners, and more specifically, to an air inlet structure of an air conditioner with a dustproof function. Background Art

[0002] HVAC is an air conditioner with heating, ventilation and air conditioning functions. Since the main functions of HVAC include heating, ventilation and air conditioning, the comprehensive abbreviation of these three functions is HVAC. HVAC often has a filtering device at the air inlet to filter dust and impurities in the air. The dustproof net can prevent dust from entering the equipment.

[0003] After searching, the Chinese utility model patent with publication number CN217763800U discloses an air inlet filter device for HVAC, which relates to the field of HVAC technology. It solves the technical problem that the air inlet filter device is generally fixed inside the air inlet by bolts, etc., and the bolts need to be removed one by one during disassembly, which increases the operation steps and is cumbersome to disassemble. After long-term use, it is easy to cause mesh blockage, and the air permeability decreases accordingly. The dust removal effect is significantly weakened, and it is difficult to clean the dust attached to the surface of the mesh plate in the later stage.

[0004] The above-mentioned air inlet filter device uses a method of removing the dust plate to clean the dust, which requires manual cleaning, is time-consuming and labor-intensive, and due to the different installation positions of the HVAC, there may be dangers during operation. Therefore, the need to design an air-conditioning air inlet that can automatically clean the filter is a problem that needs to be solved at present. Utility Model Content

The bottom inner wall is located below the first vertical plate and is staggeredly installed with several V-shaped guide plates in the horizontal direction; a movable plate is arranged inside the protective shell just above the filter; a plurality of cleaning needles matching the internal holes of the filter are arranged at the bottom of the movable plate; a cylinder for driving the movable plate to rise and fall is installed on the top inner wall of the protective shell; the top inner wall of the protective shell is located above the second vertical plate and is fixedly connected with the third vertical plate in the vertical direction; a dust collection hole is arranged at the bottom of the protective shell below the filter, and a horizontal plate is arranged at the bottom of the protective shell on the inner side of the dust collection hole in the horizontal direction; a horizontal driving mechanism for driving the horizontal plate to move is installed at the bottom of the protective shell.

[0007] As a further improvement of the technical solution of the utility model, the edge of the air inlet grille is fixedly connected to the end of the protective shell by screws, and the end of the protective shell is fixedly connected to the outer wall of the air conditioner body by screws.

[0008] As a further improvement of the technical solution of the utility model, the two ends of the V-shaped guide plate in the horizontal direction are fixedly connected to the two inner walls of the protective shell by screws.

[0009] As a further improvement of the technical solution of the utility model, a limiting block is provided at one end of the movable plate near the outer wall of the first vertical plate, and a limiting sliding groove is provided along the vertical direction on the outer side of the end of the outer wall of the first vertical plate corresponding to the limiting block.

[0010] As a further improvement of the technical solution of the utility model, the cylinder is fixedly connected to the top inner wall of the protective shell by screws, and the output end of the cylinder is vertically downwardly fixedly connected to the top of the movable plate by screws.

[0012] As a further improvement of the technical solution of the utility model, a contraction groove for the lateral movement of the cross plate is provided at the bottom of the protective shell.

[0013] Beneficial effects of the utility model:

[0014] 1. When in use, the air is initially filtered through the air inlet grille. After entering the protective shell, the air is guided through multiple V-shaped guide plates arranged in a staggered manner. The design of multiple V-shaped guide plates arranged in a staggered manner allows some adhesives in the air to adhere to the surface of the V-shaped guide plates, thereby reducing the problem of adhesives adhering to the filter net, causing dust to be difficult to fall off;

[0015] 2. A structure is provided to facilitate the cleaning of the filter, so as to prevent dust from entering the air inlet of the air conditioner. When in use, the movable plate is driven down by controlling the operation of the cylinder, and the impurities in the holes of the filter are cleaned by cleaning the bottom of the movable plate, so that the dust or impurities attached to the filter are separated from the filter and fall on the horizontal plate at the bottom of the protective shell. The horizontal plate is driven to shrink to the inside of the shrinkage groove by starting the horizontal driving mechanism. During the shrinkage process, the dust or impurities on the top of the horizontal plate collide with the end of the shrinkage groove, and the dust on the top of the horizontal plate can be pushed down during the movement of the horizontal plate. The horizontal plate can also be retracted in advance before the cylinder is started, so that the dust or impurities fall directly to the outside of the protective shell, and can be reset after cleaning.
