Furthermore, the terms "first" and "second" are used only for descriptive purposes and are not intended to have a special meaning.

The technical scheme of the utility model is further explained by the specific implementation mode in combination with the attached drawings.

As shown in fig. 1 and 2, the present embodiment provides a cooling/heating air door structure 10, which is disposed in an air conditioning box 100, and can realize linear temperature adjustment of each mode of the air conditioning box 100 without changing the casing of the air conditioning box 100, thereby solving the problem of low air mixing ratio in the initial design of the air conditioning box 100.

Specifically, the cooling/heating air door structure 10 includes a first cooling/heating air door 1 and a second cooling/heating air door 2 which are oppositely disposed and abutted along a first direction, that is, the cooling/heating air doors are disposed in a group, and they are mutually matched to realize various performances of the cooling/heating air door structure 10. Wherein, the first cold-warm air door 1 and the second cold-warm air door 2 both comprise a cold flow plate 11 and a warm flow plate 12, and the first direction is the X direction shown in the figure.

As shown in fig. 3 to 5, when the air conditioner door structure 10 is installed in the air conditioning case 100, the cold flow plate 11 is used to split the cold air cooled by the refrigeration equipment 20, and the warm flow plate 12 is used to split the warm air heated by the heating equipment 30. In the initial design of the air conditioning box 100, because the hot air entering the channels of the side-blowing surface and the rear-blowing surface is too much, the temperature of the outlet 60 of the side-blowing surface and the temperature of the outlet 40 of the rear-blowing surface are higher than that of the outlet 50 of the middle-blowing surface, so that the left temperature of the driver is high, the right temperature is low, the left temperature of the secondary driver and passenger is low, the right temperature is high, and the temperature of the front and rear passengers is not consistent. Therefore, the wind shield 13 is added to the rear blowing surface and the middle blowing surface at the position of the cold air inlet so as to adjust the amount of cold air entering the channel of the rear blowing surface and the middle blowing surface. Specifically, as shown in fig. 2, the wind deflector 13 is disposed on the flow plate 11 in an extending manner along the first direction, and the wind deflector 13 includes a first wind-shielding portion 131 and a second wind-shielding portion 132 connected to each other, the first wind-shielding portion 131 faces the rear blowing surface outlet 40 of the air conditioning box 100, and the second wind-shielding portion 132 faces the middle blowing surface outlet 50 of the air conditioning box 100. It can be known that setting up the deep bead 13 will reduce the entering volume of cold wind, and the deep bead 13 is higher, and the entering volume of cold wind is less more, and the temperature is higher, consequently for solving the low problem of the temperature of well blown surface export 50, need set up the height that is higher than the height that is just keeping out wind a portion 131 of the back blown surface export 40 of air-conditioning box 100 to two portions 132 that keep out the wind of well blown surface export 50 of air-conditioning box 100. In addition, since the temperature of the air at the side blowing surface outlet 60 of the air conditioning box 100 is the highest at the time of initial design, the wind shielding plate 13 is not provided to shield the cold air entering the side blowing surface passage of the air conditioning box 100, that is, the amount of the cold air entering the side blowing surface passage is the largest.

Further, since the smaller the hot air side resistance, the higher the air mixing ratio, but when the air conditioning box 100 is initially designed, the hot air side resistance is larger, and the throat of the hot runner is more shielded by the tail end of the cooling and heating air door, the hot air side resistance can be controlled by forming the flow guide holes on the cooling and heating air door, thereby achieving the effect of adjusting the air mixing ratio. Specifically, as shown in fig. 1, the diversion holes include a first diversion hole 121 and a second diversion hole 122, and the ratio of hot air in the front foot-blowing outlet 70 and the rear foot-blowing outlet 80 can be controlled by adjusting the opening positions of the first diversion hole 121 and the second diversion hole 122, so as to control the temperature of the front foot-blowing outlet 70 and the rear foot-blowing outlet 80. The first guiding hole 121 is used to increase the amount of hot air entering the rear foot-blowing channel of the air-conditioning box 100, and the second guiding hole 122 is used to increase the amount of hot air entering the front foot-blowing channel of the air-conditioning box 100. As shown in fig. 4, the hot wind flows through the front foot-blowing outlet 70 and then flows to the rear foot-blowing outlet 80, and the front foot-blowing outlet 70 supplies the wind from both sides and the rear foot-blowing outlet 80 supplies the wind from the middle according to the structural design of the air-conditioning case 100. Therefore, the first diversion hole 121 is disposed in the middle of the cooling/heating air door structure 10 along the first direction, and the second diversion hole 122 is disposed on the side of the cooling/heating air door structure 10, so that even though the hot air passing through the first diversion hole 121 flows through the front foot blowing outlet 70 first, most of the hot air will flow to the rear foot blowing outlet 80 under the influence of the kinetic energy thereof, so as to increase the hot air volume of the rear foot blowing outlet 80.

Further, based on the structural design of the air conditioning cabinet 100 itself, referring to fig. 2, it can be seen that the rear-blowing surface outlet 40 is located in the middle of the middle-blowing surface outlet 50, and then a part of the cold air is located at the boundary, i.e. may enter the rear-blowing surface channel or the middle-blowing surface channel. In the present embodiment, the second wind shielding portion 132 is configured in a step shape, specifically, the second wind shielding portion 132 includes a first rectangular plate 1321 and a second rectangular plate 1322, the first rectangular plate 1321 is connected to the first wind shielding portion 131 through the second rectangular plate 1322, and the height of the first rectangular plate 1321 is higher than that of the second rectangular plate 1322. In addition, the height of the rectangular two plates 1322 is higher than that of the first wind shielding part 131, and the stepped structure design can further improve the flow field distribution at the boundary, so that the flow rate of cold air entering the middle blowing surface is kept constant by changing the air flow direction.
