Description

Technical Field

[0001] This utility model relates to the field of automotive air conditioning filtration, specifically to an integrated filter structure, an automotive air conditioner, and an automobile. Background Technology

[0002] A Chinese patent with publication number CN221757319U discloses a filter for automotive air conditioning, relating to the technical field of automotive air conditioning filter technology. Specifically, it includes a filter frame with a double-layer filter slidably connected to its inner wall. A rod is fixedly connected to the bottom surface of the double-layer filter, and the outer surface of the rod is slidably connected to the filter frame. A first placement box is fixedly connected to the bottom surface of the filter frame, and a first spring is fixedly connected to the inner bottom wall of the first placement box. A push block is fixedly connected to the top of the first spring. Through the cooperation between a second spring, a connecting rod, and the second placement box, the connecting rod can consistently apply a horizontal force to the filter frame through the elastic force of the second spring. The sliding connection between the connecting rod and the slot allows the connecting rod to engage with the slot when the double-layer filter is placed in the filter frame, thus achieving the effect of quickly installing and fixing the double-layer filter through the engagement of the slot and the connecting rod.

[0003] The filter with publication number CN221757319U is rectangular. Currently, automotive air conditioners on the market are roughly divided into three categories according to their layout: offset air conditioners, center-mounted air conditioners, and split air conditioners. The corresponding filter elements are mostly rectangular in shape. There are two main integrated structures in automotive air conditioners: one is arranged between the air inlet and the blower, with the filter element placed horizontally; the other is arranged between the blower and the evaporator, with the filter element placed vertically.

[0004] Both filter layouts have their advantages and disadvantages. The first, the horizontal layout, is limited by filtration efficiency requirements. Typically, the filter element area is larger than the front air inlet and rear blower end. Therefore, airflow mainly passes through the middle area of ​​the filter element, creating dead zones around the perimeter, especially at the four corners, resulting in wasted filtration area. Furthermore, to accommodate after-sales filter element removal and installation routes, this integrated method requires additional openings in the glove box for filter element replacement, increasing the cost of the glove box and making it less aesthetically pleasing.

[0005] The second type of filter element, with its vertical placement, requires the filter element to be split into two stacked pieces to reduce the height needed for disassembly and assembly, thus increasing costs due to its proximity to the evaporator and the consistently humid working environment. Furthermore, the filter's location makes it highly susceptible to bacterial growth, mold, and unpleasant odors, leading to customer complaints. Utility Model Content

[0018] The present invention will now be described in detail with reference to specific embodiments. These embodiments will help those skilled in the art to further understand the present invention, but do not limit the present invention in any way. It should be noted that those skilled in the art can make several changes and improvements without departing from the concept of the present invention. These all fall within the protection scope of the present invention.

[0019] like Figure 1 as well as Figure 4 As shown, a filter integration structure provided by this utility model includes: an annular filter element 1 and a filter element housing; The filter housing is used to install the annular filter 1 on the air intake volute 4 of the blower. The annular filter 1 includes several filter surfaces. The airflow field entering the annular filter 1 is involute. The air moves around the circumference of the annular filter 1, passes through the filter surfaces of the annular filter 1 in sequence, and then enters the blower. The annular filter 1 is used to filter the air entering the blower.

[0020] The filter housing mounts the annular filter element 1 onto the blower's intake volute. When the blower operates, it draws in air. The air enters the blower through the intake channel with an involute-shaped flow pattern, as shown in the image. Figure 3 As shown, the annular filter element 1 matches the airflow direction. The air moves in a circular motion inside the annular filter element 1 and is filtered sequentially through the filter surface in the annular filter element 1. The air enters the blower after passing through the annular filter element 1. During the process of the air being drawn in by the blower, the annular filter element 1 filters the passing air.

[0021] The annular filter element 1 is designed to match the airflow direction entering the blower. All air entering the blower passes through the annular filter element 1, fully utilizing its effective area and maximizing its filtration performance. The integrated filter structure is located on the blower's intake volute, facilitating easy access and eliminating the need for additional openings in the glove box for filter replacement. Furthermore, the integrated annular filter element reduces cost. Its placement on the blower's intake volute, away from the evaporator, achieves dry and wet separation, preventing mold and odor buildup and extending its service life.

[0022] In one feasible implementation, such as Figure 1 as well as Figure 2 As shown, the filter housing includes an upper filter housing 2 and a lower filter housing 3. The upper filter housing 2 is used to mount the annular filter element 1. The upper filter housing 2 is detachably mounted on the lower filter housing 3, and the lower filter housing 3 is detachably mounted on the intake volute. The lower filter housing 3 is detachably mounted on the intake volute. When it is necessary to remove or install the integrated filter structure from the intake volute, the lower filter housing 3 is directly removed or installed, thereby achieving the removal or installation of the entire integrated filter structure. The upper filter housing 2 is detachably mounted on the lower filter housing 3. When the annular filter element 1 needs to be replaced, the upper filter housing 2 is removed from the lower filter housing 3, thereby facilitating the replacement of the annular filter element 1.

[0023] Specifically, a portion of the upper housing 2 of the filter element abuts against the outer surface of the annular filter element 1, and a portion of the lower housing 3 of the filter element abuts against a portion of the inner surface of the annular filter element 1. After the annular filter element 1 is installed on the upper housing 2, the lower housing 3 is installed on the upper housing 2. At this time, the portions of the upper housing 2 and the lower housing 3 of the filter element clamp the annular filter element 1 between them, thereby fixing the annular filter element 1 in the filter element housing.

[0024] Specifically, such as Figure 5 As shown, the filter element housing 2 has screw holes 21, and screws are used to fix the filter element housing to the intake volute through the screw holes 21. This allows the filter element housing to be detachably installed on the intake volute.

[0025] Specifically, the upper housing 2 and the lower housing 3 of the filter element are respectively provided with ribs and grooves. The upper housing 2 and the lower housing 3 of the filter element are installed by pressing together through the ribs and grooves. This allows for the detachable installation of the upper housing 2 and the lower housing 3 of the filter element and ensures the reliability of their installation.

[0026] This utility model also provides an automotive air conditioner, which adopts the filter integration structure of any one of the above; the filter integration structure is disposed on the air intake volute of the blower.

[0027] This utility model also provides a car that uses the above-mentioned car air conditioner; the car also includes a body structure, and the car air conditioner is installed inside the body structure.

[0028] In one feasible implementation, the blower's intake volute is located in the engine compartment of the vehicle body structure. Simultaneously, the integrated filter structure is placed outside the front bulkhead sheet metal, i.e., in the engine compartment, physically isolating the air conditioning intake and exhaust components, effectively reducing noise. Placing the intake side in the engine compartment frees up more foot space and saves the overall vehicle space occupied by the traditional passenger side layout. It also facilitates after-sales disassembly and installation, eliminating the need for an additional opening in the glove box for matching, thus solving many drawbacks of traditional filter placement within the vehicle and better suiting the practical application of automotive air conditioning.

[0029] Working principle: An annular filter element 1 is installed on the upper housing 2 of the filter element, with its outer surface abutting against a portion of the upper housing 1. A lower housing 3 is installed on the upper housing 2, with its inner surface abutting against a portion of the lower housing 3. The annular filter element 1 is fixed within the filter element housing. The filter element housing integrates the filter structure and is installed on the intake volute by screws passing through the screw holes 21 on the filter element housing. When the blower operates, it draws in air, which enters the blower from the annular filter element 1 in an involute flow pattern. The annular filter element 1 matches the air flow pattern, causing the air to move in a circular motion within the annular filter element 1. The air is filtered sequentially through the filter surfaces within the annular filter element 1. All air passes through the annular filter element 1 before entering the blower. Thus, during the process of air being drawn in by the blower, the annular filter element 1 filters the passing air.

[0030] When it is necessary to replace the annular filter element 1, remove the screws and remove the filter integration structure from the intake volute. Remove the upper filter housing 2 from the lower filter housing 3, and then remove the annular filter element 1 from the upper filter housing 2. Install the new annular filter element 1 onto the upper filter housing 2, and repeat the above installation steps.
