However, because the air inlet of the existing air conditioning box is directly communicated with the air return inlet through the air door, the air flow can directly pass through the air door to enter the air return inlet after entering from the air inlet or reversely circulate, so that the air flow directly enters the vehicle without being converted by the temperature converter, the temperature in the vehicle is disordered, and the riding feeling is reduced. This application provides an air-conditioning box based on this basis to can avoid appearing above-mentioned condition. The following description will be made by way of example.

An aspect of the embodiment of the utility model provides an air-conditioning box, as shown in fig. 1, be applied to the car, include: a box body 10 and a damper 20 positioned in an inner chamber of the box body 10; the box body 10 comprises an air inlet 101, an air return 102 and an air outlet 103 which are arranged on the body of the box body 10; the air door 20 is located between the air inlet 101 and the air return opening 102, the air door 20 includes a baffle 201 and side plates 202 located at two ends of the baffle 201 and arranged oppositely, the side plates 202 are rotatably connected with the inner wall of the box 10, and a flow guide part 203 is further formed between the side plates 202 to guide the air flow entering through the air inlet 101 to flow out through the air outlet 103.

Illustratively, the damper 20 is disposed inside the housing 10, i.e., the housing 10 includes an inner chamber. Meanwhile, to switch the modes, the damper 20 should be rotated with respect to the housing 10. In order to realize the air intake function of the air conditioning box, as shown in fig. 1, an air inlet 101, an air return 102 and an air outlet 103 may be further disposed on the outer wall of the box body 10. The damper 20 includes a baffle 201 and side plates 202 disposed at two ends of the baffle 201, and the baffle 201 is rotatably connected to the inner wall of the box 10 through the side plates 202, so that the baffle 201 can cooperate with the air inlet 101 and the air return 102 to realize different modes (i.e. mode selection, which is actively selected by a passenger or a driver in the vehicle), for example: after the baffle 201 closes the air inlet 101, airflow enters the air conditioning box from the interior of the vehicle and then circulates into the interior of the vehicle; when the baffle 201 is positioned between the air inlet 101 and the air return inlet 102, the air inlet 101 and the air return inlet 102 are both in an opening state, at the moment, a part of air flow enters the air conditioning box from the inside of the vehicle, and the other part of air flow enters the air conditioning box from the outside and then enters the air mixing mode of the cab in the vehicle together; when the baffle 201 closes the air return opening 102, the air flow forms an external circulation mode which enters the air conditioning box from the outside and then enters the vehicle.

Referring to fig. 1, a flow guiding portion 203 may be further formed between the two opposite side plates 202, that is, in fig. 1, the flow guiding portion 203 is formed from one side plate 202 to the other side plate 202, wherein the flow guiding portion 203 may be disposed on the baffle plate 201 and extend toward the side plate 202 away from the baffle plate 201. Or may extend in the direction of the side plate 202 on one side toward the side plate 202 on the other side. The air mixing baffle plate can be in any shape, and when the air mixing baffle plate 201 is located between the air inlet 101 and the air outlet 103, the air flow entering the inner cavity of the box body 10 from the air inlet 101 and the air flow entering the inner cavity of the box body 10 from the cab in the vehicle through the air return opening 102 form a partition and a drainage to enable the air flow and the air flow to be combined to enter the air outlet 103, the air flow and the drainage are enabled not to generate convection directly as far as possible, and when the flow rate of the external air flow is large, the external air flow is enabled to directly enter the cab in the vehicle through the air return opening 102, the temperature in the vehicle is enabled to be disordered, and the riding experience.

As shown in fig. 4, the dotted line represents the airflow path, and the arrow at the end of the dotted line represents the direction of the airflow. After outside air current gets into inside the box 10 through air intake 101, flow guide portion 203 in air door 20 conducts the drainage and makes it flow out from the air outlet 103 of box 10 bottom, and after the air current in the driver's cabin got into inside the box 10 through return air inlet 102 in the car, flow guide portion 203 in air door 20 conducts the drainage and makes it flow out from the air outlet 103 of box 10 bottom to can guide outside air current to get into temperature converter inside, make the temperature in the car can adjust according to the mode of predetermineeing.

First, the side plate 202 of the damper 20 is rotatably connected to the inner wall of the casing 10, and as shown in fig. 1, a mounting hole 105 is formed in the inner wall of the casing 10, a rotating shaft 204 is formed in the side plate 202 of the damper 20, and the mode can be selected by rotating the mounting hole 105 and the rotating shaft 204 in cooperation. Of course, the inner wall of the box 10 may also be provided with a rotating shaft 204, and the side plate 202 of the damper 20 may be provided with a mounting hole 105, etc., which is not particularly limited in this application as long as the rotation of the two side plates 202 of the damper 20 and the box 10 can be realized.

Secondly, the baffle 201 can be in the shape of a flat plate, an arc shape matched with the inner wall of the box body 10, and the like; the side plate 202 may be in the shape of a sector, a triangle, or other forms, and the present application does not specifically limit the side plate, as long as the two can cooperate with each other to form a door-shaped structure.

Thirdly, in order to enable the baffle 201 to form a better sealing structure with the frames of the air inlet 101 and the air return 102 when the air inlet 101 or the air return 102 is closed, a sealing enclosure, such as a sealing strip 205 shown in fig. 1, may be further formed at the side ends of the baffle 201 and the two side plates 202. The sealing strip 205 may illustratively be a rubber strip, a silicone strip, or the like.

Optionally, the flow guiding portion 203 is attached to the baffle 201 and the side plate 202 respectively.

For example, as shown in fig. 2, in order to further prevent the airflow of the air inlet 101 and the airflow of the air return 102 from directly convecting, and reduce the possibility of the convection between the airflow of the air inlet 101 and the airflow of the air return 102, the flow guide portion 203 should be attached to the baffle 201 and the side plate 202, and meanwhile, the material or structure of the flow guide portion 203 should be selected according to actual requirements, so that the flow guide portion 203 is a solid structure through which the airflow cannot directly pass. Such as steel plate, stainless steel, etc. Thus, an integral partition structure can be formed between the baffle plate 201 and the two side plates 202 of the damper 20. In addition, the width of the partition structure (i.e., the width in the direction from the baffle 201 to the rotation axis of the side plate 202) may be set appropriately according to the basis of partitioning the area where the direct convection of the air flow of the air inlet 101 and the air flow of the air return 102 may occur. In order to avoid the interference between the damper 20 and the box 10 when the damper 20 rotates due to the excessively wide width, the extending end away from the baffle 201 should not exceed the rotating shaft after being attached to the baffle 201 and the side plate 202.

Optionally, the cross section of the flow guide part 203 parallel to the side plate 202 is triangular.

For example, as shown in fig. 3, a cross section of the flow guiding portion 203 parallel to the side plate 202 may also be a triangle, and in order to reduce the impact force between the flow guiding portion 203 and the airflow of the air inlet 101 and the airflow of the air return 102, a contact surface between the flow guiding portion 203 and the two airflows should be an inclined surface, and in order to reduce the manufacturing cost, the flow guiding portion 203 may also have two inclined surfaces forming an included angle, and the inside is a hollow structure. In order to improve the strength, a stopper 206 may be further disposed on the sidewall, and a support structure 207 may be formed inside the flow guide portion 203. The position-limiting member 206 can be a position-limiting protrusion, a position-limiting buckle, etc., and the supporting structure 207 can be a supporting column, a supporting rod, etc.

Optionally, the cross section of the flow guide part 203 parallel to the side plate 202 is fan-shaped.

For example, the section of the flow guide portion 203 parallel to the side plate 202 may also be a sector, and similarly, in this structure, a stopper 206, a support structure 207, and the like may be added to improve the strength, so that the flow guide portion 203 has higher stability when guiding the air fluidity.

Optionally, the cross section of the flow guide part 203 parallel to the side plate 202 is trapezoidal.

For example, the cross section of the flow guiding portion 203 parallel to the side plate 202 may be a trapezoid, and in order to reduce the airflow resistance, when the damper 20 is pivotally installed on the box 10 as shown in fig. 1, the shorter side end of the trapezoid should face the air outlet 103, and the longer side end should face the baffle 201. Therefore, when the air flow is contacted, a low-resistance drainage structure can be formed by utilizing the inclined surface.

Optionally, one surface of the flow guiding portion 203 close to the air inlet 101 is a flow guiding surface, and the flow guiding surface is an arc surface.

For example, the flow guide part 203 may be integrally formed with the baffle 201 and the side plate 202 of the damper 20, or the flow guide part 203 may be separately formed and assembled. After the diversion portion 203 is formed separately, in order to better form diversion on the airflow and reduce the impact of the airflow and the diversion portion, one surface of the diversion portion facing the air inlet 101 is a diversion surface, and a low-resistance structure during diversion can be formed by utilizing a cambered surface structure. It should be noted that a similar low-resistance structure may be provided on a surface of the flow guide portion 203 facing the air return opening 102. Meanwhile, the two flow guide surfaces are arranged oppositely and form an included angle, and meanwhile, one end of the included angle faces the air outlet 103, so that the air flow can be guided in a low-resistance flow guide mode, and meanwhile, the two air flows can be gradually close to each other in the same direction to form a confluence. The phenomenon of convection can be effectively avoided during confluence.

Optionally, a blocking protrusion 104 is further disposed on the inner wall of the box 10, the blocking protrusion 104 is disposed corresponding to the baffle 201, and a gap 107 is formed between the blocking protrusion 104 and the baffle 201.

For example, in order to further improve that in the air mixing mode, the damper 20 forms a better partition to prevent the air flow of the air inlet 101 and the air flow of the air return 102 from forming strong convection, as shown in fig. 1 and 4, a blocking protrusion 104 may be further formed between the baffle 201 and the inner wall of the box 10. That is, referring to fig. 4, after the external air enters the inside of the box 10 through the air inlet 101, a part of the air enters the area between the baffle 201 and the inner wall of the box 10, and at this time, the blocking protrusion 104 is formed on the inner wall of the box 10 (the blocking protrusion 104 is disposed between the air inlet 101 and the air return 102 and corresponds to the baffle 201 in the air mixing mode), so as to block the air flow in the area. Meanwhile, in order not to affect the rotation of the damper 20 to a certain extent, a certain gap 107 is formed between the blocking protrusion 104 and the baffle 201, and the size of the gap 107 can be set reasonably as required. In addition, the blocking protrusion 104 may have a bar shape as shown in fig. 5, both ends of which are fixed by fixing grooves 106 formed on the inner wall of the case 10, or may have various forms such as being welded to the inner wall of the case 10.

Optionally, the blocking tab 104 extends in a direction from one side panel 202 to the other side panel 202 of the damper 20.

For example, as shown in fig. 1, to further improve the blocking effect, the blocking protrusion 104 may also extend along a direction from one side plate 202 to the other side plate 202 of the damper 20.

The embodiment of the utility model provides a on-vehicle air conditioner is provided to another aspect, including any kind of air-conditioning box of temperature converter and the aforesaid, the air outlet 103 and the temperature converter intercommunication of air-conditioning box.

For example, the air conditioning box is applied to an air conditioning system mounted on a vehicle, and meanwhile, the air outlet 103 of the air conditioning box is communicated with the temperature converter. Therefore, under the air mixing mode, the temperature of the two air flows is adjusted through the temperature converter, and the adjustment requirement of the temperature in the vehicle can be met.

The embodiment of the utility model provides a further aspect provides a car, including driver's cabin and foretell vehicle air conditioner, vehicle air conditioner's temperature converter and driver's cabin intercommunication, the return air inlet 102 and the driver's cabin intercommunication of air-conditioning box.

For example, when the vehicle air conditioner is applied to an automobile, the cab is directly communicated with the return air inlet 102, the temperature converter is directly communicated with the cab, and a passage from the air outlet 103 to the temperature converter to the cab is formed. Therefore, the phenomenon that in the air mixing mode, the air inlet 101 on the air conditioner box body 10 body is directly communicated with the air return inlet 102 through the traditional air door 20 to cause interference of two air flows, and even when the vehicle speed is too high, the external air flow directly flows backwards to enter the vehicle to cause temperature imbalance in the vehicle can be avoided.
