Description

Technical Field

[0001] This utility model belongs to the field of automotive air conditioning boxes, specifically relating to a mixed air rectifier air conditioning box. Background Technology

[0002] During the design process of automotive air conditioning units, due to installation space constraints, the structure needs to be integrated and miniaturized. For some models, cold and hot air are designed to directly mix and flow against each other inside the air conditioning unit before being discharged through several vents. The drawback of this design is that the mixing of cold and hot air can easily create vortices, which can lead to sharp noise. Therefore, a rectifier structure is needed to straighten the air before it is discharged through the vents. Conventional rectifier structures occupy space and are not conducive to the miniaturization of the air conditioning unit. Utility Model Content

[0003] The purpose of this utility model is to provide a mixed air rectifier air conditioning unit to solve the above-mentioned problems.

[0004] This utility model achieves the above objectives through the following technical solutions:

[0005] A mixing and rectifying air conditioning unit includes a housing, an air inlet, a mixing chamber, and several air outlets disposed within the housing. The air inlet and the mixing chamber are connected by two flow channels, one of which is equipped with a heating device. A mixing guide plate is disposed within the mixing chamber to allow hot and cold air from the two flow channels to enter the mixing chamber and counteract each other. Each air outlet is equipped with an air outlet rectifying assembly, which includes a shaft and at least three plates disposed on the shaft. The plates serve as air outlet valve plates and / or rectifying plates.

[0006] As a further optimization of this utility model, the air inlet is provided with a first air inlet valve plate for guiding airflow into the two flow channels, and the flow channel with the heating device is also provided with a second air inlet valve plate. This solution adjusts the airflow entering the air inlet by setting the first air inlet valve plate, and guides part of the airflow into the flow channel with the heating device for heating, so as to facilitate mixing after heating.

[0007] As a further optimization of this utility model, a first rectifier plate is also provided in the mixing chamber. The first rectifier plate is used to eliminate the vortex generated by the collision of hot and cold air. By providing the first rectifier plate in the mixing chamber, the generation of vortex can be initially blocked.

[0008] As a further optimization of this utility model, the air outlet includes a first air outlet, a second air outlet, and a third air outlet. The first air outlet and the second air outlet face the same direction, while the third air outlet faces the opposite direction. This solution provides a specific air outlet setting, in which the air outlets are set on the upper and lower sides, so that the shaft of the air outlet rectification component can extend parallel outside the box body, which facilitates integrated control of opening and closing.

[0009] As a further optimization of this utility model, each of the shafts is provided with four plates, and the cross-sections of the four plates are distributed in an X-shape. This solution provides four plates on the air outlet rectifier assembly, so that the plates not only serve as air outlet valve plates, but also act as rectifier plates in the mixing chamber, effectively eliminating noise and turbulence.

[0010] As a further optimization of this utility model, a second rectifier plate is provided on one of the air outlet rectifier components. In this solution, the first air outlet is closest to the mixing chamber. Therefore, a second rectifier plate is provided on the air outlet rectifier component corresponding to the first air outlet to further eliminate vortices.

[0011] The beneficial effects of this utility model are as follows:

[0012] This utility model, by setting multiple plates on the valve plate of the air outlet, allows the air outlet rectifier assembly to act as an air outlet valve plate to control the opening and closing of the air outlet. In both the open and closed states, the air outlet valve plate has at least one plate placed in the mixing chamber for rectification, giving the plates on the shaft multiple uses, saving the space of setting a separate rectifier plate, and facilitating the miniaturization of the air conditioning unit.

[0020] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0021] Example 1

[0022] like Figure 1-6 As shown, a mixed-air rectification air conditioning unit includes a housing 1, an air inlet 101, a mixing chamber 2, and several air outlets disposed within the housing 1. The air inlet 101 and the mixing chamber 2 are connected by two flow channels, one of which is equipped with a heating device 5. A mixing guide plate 3 is disposed within the mixing chamber 2 to allow the hot and cold air from the two flow channels to enter the mixing chamber 2 and collide. Each air outlet is equipped with an air outlet rectification assembly 8, which includes a shaft 801 and at least three plates 802 disposed on the shaft 801. The plates 802 serve as air outlet valve plates and / or rectification plates.

[0023] This solution sets multiple plates 802 on the valve plate of the air outlet, so that the air outlet rectifier assembly 8 can act as an air outlet valve plate to control the opening and closing of the air outlet. In both the open and closed states, the air outlet valve plate has at least one plate 802 placed in the mixing chamber 2 for rectification, so that the plate 802 on the shaft 801 has multiple uses, saving the space of setting the rectifier plate separately, which is conducive to the miniaturization of the air conditioning unit.

[0024] The air inlet 101 is equipped with a first air inlet valve plate 4 for guiding airflow into the two flow channels. The flow channel where the heating device 5 is installed is also equipped with a second air inlet valve plate 6. This solution adjusts the airflow entering the air inlet 101 by setting the first air inlet valve plate 6, and guides part of the airflow into the flow channel with the heating device 5 for heating, so as to facilitate mixing after heating. The heating device 5 can be set as a heat exchange structure or an electric heating structure as needed.

[0025] The mixing chamber 2 is also equipped with a first rectifier plate 7, which is used to eliminate vortices generated by the collision of hot and cold air, such as... Figure 5As shown in the airflow direction, the heated airflow rises and mixes with the cold air. By setting the first rectifier plate 7 in the mixing chamber 2, the generation of vortices can be initially blocked.

[0026] The air outlet includes a first air outlet 102, a second air outlet 103, and a third air outlet 104. The first air outlet 102 and the second air outlet 103 face the same direction, while the third air outlet 104 faces the opposite direction. This solution provides a specific air outlet setting, in which the air outlets are set on the upper and lower sides. Then, the shaft 801 of the air outlet rectification component 8 can extend parallel to the outside of the housing 1, which facilitates integrated control of opening and closing. In general, existing technologies use a mode disk for guidance and control multiple shafts 801 to open and close in a coordinated manner.

[0027] Each shaft 801 is equipped with four plates 802, which are arranged in an X-shape. This design, by setting four plates 802 on the air outlet rectifier assembly 8, allows the plates 802 to not only function as air outlet valves but also as rectifiers within the mixing chamber 2, effectively eliminating noise and turbulence. At least one of the plates 802 on the air outlet rectifier assembly 8 has a different length, allowing the longer plates 802 to extend into the mixing chamber 2 for thorough rectification. Figure 4 As shown, since the air outlet rectifier 8 of the first air outlet 102 is closest to the mixing chamber 2, a longer valve 802 is provided on the air outlet rectifier 8 to enter the mixing chamber 2.

[0028] Furthermore, a second rectifier plate 803 is provided on the plate 802 of the air outlet 102 air outlet rectification component 8. In this scheme, the first air outlet 101 is closest to the mixing chamber 2. Therefore, the second rectifier plate 803 is provided on the air outlet rectification component 8 corresponding to the first air outlet 101 to further eliminate vortices. The second rectifier plate 803 is perpendicular to the plate 802 on the air outlet rectification component 8.

[0029] The specific implementation method is as follows: Figure 5 and Figure 6 As shown, the double arrows indicate the airflow direction, and the single arrow indicates the rotation direction of the air outlet rectifier plate 8. The airflow enters from the air inlet 101, is guided by the first air inlet valve plate 4 through two flow channels, and then undergoes counter-current mixing in the mixing chamber 2. After being rectified by the first rectifier plate 7 and the plate 802, it is discharged from the open air outlet.

[0030] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
