Description

Technical Field

[0001] This utility model relates to the technical field of vehicle air conditioning accessories, specifically a vehicle air conditioning blower structure. Background Technology

[0002] With the rapid development of the automotive industry, users' requirements for the comfort of the car's interior environment are increasing. As one of the key components affecting the air quality and temperature regulation inside the car, the importance of the vehicle air conditioning system is self-evident. The blower structure is used to guide outside air into the vehicle air conditioning system for further processing (such as heating or cooling and then blowing it to passengers). Currently, most blower structures on the market mainly focus on the intake and distribution of air, lacking an effective management mechanism for moisture in the air. Especially in situations with high external humidity (such as rainy days or high humidity climates), the air will contain a large amount of moisture. This moisture may accumulate in the blower structure and its connected pipes, which may not only affect the normal operation of the equipment, but also lead to mold growth, thereby affecting the air quality inside the car. Utility Model Content

[0003] The purpose of this invention is to provide a vehicle air conditioning blower structure to solve the problem mentioned in the background art that most blower structures on the market currently focus on air intake and distribution, and lack an effective management mechanism for moisture in the air.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a vehicle air conditioning blower structure, comprising: an outer shell, wherein the outer shell includes an upper shell and a lower shell;

[0005] The upper housing is provided with an internal circulation air inlet and an external circulation air inlet, and a filter element is provided inside the upper housing;

[0006] The lower housing is provided with an impeller assembly and a first partition and a second partition sleeved on the outer wall of the impeller assembly. The first partition and the second partition are used to divide the inner cavity of the lower housing into three cavities from top to bottom.

[0007] The lower housing has airflow channels on its side wall for communicating with the three cavities.

[0008] Preferably, the airflow channel is provided with a partition plate, which is used to divide the airflow channel into two channels. The upper channel is connected to the upper cavity, and the lower channel is connected to the middle cavity and the lower cavity, respectively.

[0009] Preferably, the bottom of the inner cavity of the two flow channels gradually slopes downward along the airflow direction.

[0010] Preferably, the height of the bottom of the lower flow channel cavity is lower than the height of the bottom of the lower cavity cavity.

[0011] Preferably, the external air intake is provided with a baffle, which is stepped.

[0012] Compared with the prior art, the beneficial effects of this utility model are: by setting baffles and filter elements to intercept the moisture carried by the outside air twice, a large amount of moisture will not accumulate at the bottom of the inner cavity of the blower structure. Furthermore, by setting the first partition, the second partition and the drain hole in sequence, the water inside the lower shell is introduced into the airflow channel and discharged in a concentrated manner, further reducing the accumulation of water in the inner cavity of the blower structure and preventing the blower structure from becoming moldy.

[0017] 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.

[0018] Example 1

[0019] Please see Figure 1 , Figure 2 and Figure 3 A vehicle air conditioning blower structure includes: a housing 1, the housing 1 including an upper housing 101 and a lower housing 102, the lower housing 102 being installed at the bottom of the upper housing 101; an internal circulation air inlet 2 and an external circulation air inlet 3 are respectively opened on both sides of the upper housing 101; a filter element 4 is provided in the inner cavity of the upper housing 101, the filter element 4 is used to filter the air introduced by the internal circulation air inlet 2 and the external circulation air inlet 3, and the filter element 4 can also remove some moisture contained in the introduced air;

[0020] It should be noted that an air damper is installed inside the upper housing 101. The air damper is controlled by a motor to rotate, thereby opening or closing the internal circulation air inlet 2 and the external circulation air inlet 3.

[0021] Please see Figure 1 , Figure 2 and Figure 3 The lower housing 102 is equipped with an impeller assembly 5, which includes a motor and an impeller mounted on the motor output shaft. The impeller is vertically installed in the inner cavity of the lower housing 102. A first partition 6 and a second partition 7 are installed sequentially from top to bottom in the inner cavity of the lower housing 102. The first partition 6 and the second partition 7 are both sleeved on the outer wall of the impeller of the impeller assembly 5. The first partition 6 and the second partition 7 divide the inner cavity of the lower housing 102 into three cavities from top to bottom. An airflow channel 8 is provided on the side wall of the lower housing 102.

[0022] The airflow channel 8 has a partition plate 10 in its inner cavity. The partition plate 10 is used to divide the inner cavity of the airflow channel 8 into two channels, an upper channel and a middle channel. The upper channel is connected to the upper cavity, and the lower channel is connected to the middle cavity. A drain hole is provided at the bottom of the side wall of the lower cavity, and the drain hole is connected to the lower channel.

[0023] It should be noted that when the impeller assembly 5 operates, air enters the inner cavity of the upper housing 101 through the internal circulation air inlet 2 or the external circulation air inlet 3, and after being filtered by the filter element 4, it enters the inner cavity of the lower housing 102. The impeller assembly 5 continues to operate, introducing air into the inner cavity of the airflow channel 8, and then it is introduced into the vehicle air conditioner for further processing. When the air passing through the filter element 4 still contains moisture, the centrifugal force generated by the rotation of the impeller assembly 5 will throw the water above the first partition 6 and the second partition 7 respectively, and some water will fall to the bottom of the inner cavity of the lower housing 102. The water above the first partition 6 and the second partition 7 enters the interior of the airflow channel 8 under the guidance of the flowing air, while the water at the bottom of the inner cavity of the lower housing 102 automatically flows into the inner cavity of the airflow channel 8 and finally gathers in the drainage area for discharge.

[0024] In this implementation, as a further optimization option, please refer to [link / reference]. Figure 2 The bottom of the inner cavity of the two flow channels gradually slopes downward along the airflow direction, which facilitates the drainage of water accumulated inside the lower housing 102 into the airflow channel 8 and then out through the airflow channel 8.

[0025] In this implementation, as a further optimization option, please refer to [link / reference]. Figure 2 The bottom of the lower flow channel is lower than the bottom of the lower cavity, which makes it easier for water inside the lower cavity to be guided into the lower flow channel and avoids water accumulation inside the lower shell 102.

[0026] In this implementation, as a further optimization option, please refer to [link / reference]. Figure 1 A baffle 9 is installed at the bottom of the inner cavity of the external circulation air intake 3. The baffle 9 is stepped. The baffle 9 blocks the moisture in the air entering the external circulation air intake 3 to intercept some of the moisture.

[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
