In this case, the partial defrosting port 317 may be communicated with the rear foot blowing port 118 by rotating the rotary valve 30, and an air supply process in the rear foot blowing region may be implemented. Preferably, the rotary valve 30 may also be formed in a hemispherical structure, so that it can better cooperate with the air inlet region 12 to supply air.

Referring to fig. 4-6, the air-conditioning box 100 can supply air to different areas, and in one example, the air-conditioning box 100 includes three modes, namely a face blowing mode, a foot blowing mode and a defrosting mode.

When the air conditioning box 100 opens the face blowing mode, the rotary valve 30 can be rotated to enable the main face blowing port 311, the auxiliary face blowing port 312, the middle face blowing port 313 and the rear face blowing port 314 to be correspondingly communicated with the main face blowing port 111, the auxiliary face blowing port 112, the middle face blowing port 113 and the rear face blowing port 114 one by one, so that the face blowing function towards the face of the user in the face blowing mode is realized.

When the air conditioning box 100 is in the foot blowing mode, the rotary valve 30 may be rotated, for example, after the rotary valve 30 is rotated by 85 ° counterclockwise, the air conditioning box may be switched from the face blowing mode to the foot blowing mode. The main driving foot blowing port 315, the auxiliary driving foot blowing port 316 and the partial defrosting port 317 are respectively communicated with the main driving foot blowing port 115, the auxiliary driving foot blowing port 116 and the rear foot blowing port 118 in a one-to-one correspondence manner, and the function of blowing air towards the feet of the user in the foot blowing mode is realized.

When the air conditioning box 100 is turned on to the defrosting mode, the foot blowing mode can be switched to the defrosting mode by turning the rotary valve 30, for example, after the rotary valve 30 is rotated clockwise by 180 °. The defrosting port 317 is communicated with the defrosting port 117, and a function of blowing air toward the windshield in the defrosting mode is realized.

Referring to fig. 4-6, in some embodiments, the number of the openings 31 is multiple, the multiple openings 31 are arranged around the rotation axis Z of the rotary valve 30, and the outlet 11 and at least one of the openings 31 are located on the same circumference.

So, air outlet 11 is located same circumference with opening 31, and opening 31 accessible rotary valve 30's rotation and air outlet 11 intercommunication or cut off, and then realize the switching between a plurality of modes.

Specifically, the rotation axis Z is a central axis of the rotary valve 30 when rotating, and in the embodiment of the present application, the rotation axis Z is an axis between the center of the hemispherical spherical surface and the center of the spherical surface. Centered on the axis of rotation Z, and may include a first circumference 51, a second circumference 52, and a third circumference 53 from the center outward.

Further, as shown in fig. 2 and 3, the air outlets 11 on the first circumference 51, the air outlets 11 on the second circumference 52, and the air outlets 11 on the third circumference 53 are spaced apart from each other and do not communicate with each other. The ports 31 are located on the circumference of the rotary valve 30, and the ports 31 on the first circumference 51, the ports 31 on the second circumference 52, and the ports 31 on the third circumference 53 are spaced apart from each other and do not communicate with each other.

Still further, the first circumference 51 of the tuyere region 12 may be provided with a middle blow-out port 113 and a rear blow-out port 114, and correspondingly, the first circumference 51 of the rotary valve 30 may be provided with a middle blow-out port opening 313 and a rear blow-out port opening 314; the second circumference 52 of the tuyere region 12 may be provided with a main driving surface tuyere 111 and an auxiliary driving surface tuyere 112, and correspondingly, the second circumference 52 of the rotary valve 30 may be provided with a main driving surface tuyere 311 and an auxiliary driving surface tuyere 312; a third circumference 53 of the tuyere region 12 may be provided with a defrost tuyere 117, a main driving foot blowing tuyere 115, an auxiliary driving foot blowing tuyere 116 and a rear foot blowing tuyere 118, and correspondingly, the third circumference 53 of the rotary valve 30 may be provided with a defrost tuyere 317, a main driving foot blowing tuyere 315 and an auxiliary driving foot blowing tuyere 116.

It will be understood that one outlet opening 11 corresponds to at least one through opening 31 on the same circumference. For example, a middle blowing surface tuyere 113 is arranged on the first circumference 51 of the air-out section, and correspondingly, at least one through opening 31 is arranged on the first circumference 51 of the rotary valve 30, and the through opening 31 may be a middle blowing surface through opening 313 or a rear blowing surface tuyere 114, so that one through opening 31 is communicated with the middle blowing surface tuyere 113.

A rear foot-blowing opening 118 is provided in the third circumference 53 of the air outlet region, and correspondingly, at least one port 31 is provided in the third circumference 53 of the rotary valve 30, and this port 31 can be a defrost port 317, so that one port 31 communicates with the rear foot-blowing opening 118.

Referring to fig. 3, in some embodiments, at least two ports 31 are located on the same circumference centered on the rotation axis Z.

Thus, when one of the ports 31 is communicated with the outlet 11, the other port 31 may not be communicated with the outlet 11, and after the rotary valve 30 rotates, the other port 31 is switched to be communicated with the outlet 11, so as to realize the opening and closing of the outlet 11 and the switching between modes.

In particular, on the same circumference, the rotary valve 30 may be provided with two through openings 31. For example, the rotary valve 30 is provided with a main driving face port 311 and an auxiliary driving face port 312 on the second circumference 52, the main driving face port 311 and the auxiliary driving face port 312 can be simultaneously communicated with the main driving face port 111 and the auxiliary driving face port 112 on the second circumference 52 of the tuyere zone 12, and after the rotary valve 30 rotates by a certain angle, the main driving face port 311 and the auxiliary driving face port 312 can be simultaneously isolated from the main driving face port 111 and the auxiliary driving face port 112 on the second circumference 52 of the tuyere zone 12. Thereby realizing the opening and closing of the air outlet 11.

The rotary valve 30 may also be provided with three through openings 31 on the same circumference. For example, the rotary valve 30 may be provided with a defrost port 317, a main driving leg blowing port 115, and a sub driving leg blowing port 116 on the third circumference 53, and when the defrost port 317 is communicated with the defrost port 117 on the third circumference 53 of the tuyere zone 12, the main driving leg blowing port 315 and the sub driving leg blowing port 316 are blocked from the main driving leg blowing port 115 and the sub driving leg blowing port 116 on the third circumference 53 of the tuyere zone 12.

When the air-conditioning box 100 is in the defrosting mode, after the rotary valve 30 rotates by a certain angle (for example, rotates by 180 degrees counterclockwise), the defrosting port 317 is blocked from the defrosting port 117 on the third circumference 53 of the port area 12, and the defrosting port 317, the main driving foot blowing port 315 and the auxiliary driving foot blowing port 316 are communicated with the rear foot blowing port 118, the main driving foot blowing port 115 and the auxiliary driving foot blowing port 116 on the third circumference 53 of the port area 12, so that the air-conditioning box 100 is switched to the foot blowing mode, and further, the air-conditioning box 100 is switched between the modes.

Referring to fig. 3, in some embodiments, at least two ports 31 are located on different circumferences centered on the axis of rotation Z.

In this way, switching between the outlets 11 can be achieved by rotation of the rotary valve 30.

In particular, the rotary valve 30 may be provided with two through openings 31 on different circumferences. For example, the rotary valve 30 is provided with a middle blow port 313 on the first circumference 51, and the rotary valve 30 is provided with a defrost port 317 on the third circumference 53. The defrost port 317 is blocked from the defrost port 117 on the third perimeter 53 of the tuyere zone 12 when the middle blow-side port 313 is in communication with the middle blow-side port 113 on the first perimeter 51 of the tuyere zone 12. After the rotary valve 30 is rotated by a certain angle, the defrost port 317 is connected to the defrost port 117 at the third circumference 53 of the port area 12, and the middle blow-off port 313 is blocked from the middle blow-off port 113 at the first circumference 51 of the port area 12. Thereby realizing the switching between the air outlets 11.

The rotary valve 30 may also be provided with three through openings 31 on different circumferences. For example, the rotary valve 30 is provided with a middle blow port 313 on the first circumference 51, the rotary valve 30 is provided with a main drive blow port 311 on the second circumference 52, and the rotary valve 30 is provided with a main drive blow pin port 315 on the third circumference 53. When the middle face-blowing port 313 is communicated with the middle face-blowing port 113 on the first circumference 51, the main face-blowing port 311 is also communicated with the main face-blowing port 111 on the second circumference 52, and the main leg-blowing port 315 is isolated from the main leg-blowing port 115 on the third circumference 53. After the rotary valve 30 rotates a certain angle, the main driving face blowing port 315 is communicated with the main driving face blowing port 115 on the third circumference 53 of the tuyere zone 12, the middle face blowing port 313 is blocked from the middle face blowing port 113 on the first circumference 51 of the tuyere zone 12, and the main driving face blowing port 311 is also blocked from the main driving face blowing port 111 on the second circumference 52 of the tuyere zone 12. Thereby realizing the switching between the air outlets 11.

Referring to fig. 3, in some embodiments, at least two ports 31 are staggered along a radial direction of the rotary valve 30.

Therefore, when the rotary valve 30 is rotated, the through holes 31 in different radial directions can be communicated with the air outlet 11, so that the required opening of the air outlet 11 is realized, and the air outlet 11 which is not required is closed.

Specifically, the radial direction of the rotary valve 30 may be a direction perpendicular to the rotation axis Z of the rotary valve 30. On different circumferences, the rotary valve 30 may be provided with two through openings 31. For example, the rear blowout surface port 314 is provided in the first circumference 51, the defroster port 317 is provided in the third circumference 53, and the rear blowout surface port 314 and the defroster port 317 are not in the same radial direction of the rotary valve 30. When the rear blow-off port 314 is in communication with the rear blow-off port 114 on the first circumference 51 of the tuyere zone 12, the defrost port 317 is blocked from the defrost port 117 on the third circumference 53.

In summary, the plurality of through holes 31 may be distributed on the same circumference at the same time, the plurality of through holes 31 may also be distributed on different circumferences, and the plurality of through holes 31 may be distributed in a staggered manner in the radial direction of the rotary valve 30. In other embodiments, the plurality of openings 31 may also be distributed in the same radial direction of the rotary valve 30. This application does not do the restriction to the distribution position of opening 31, and opening 31 and air outlet 11 mutually support can realize the switching in different tuyeres and the switching between the different modes can.

Referring to fig. 2 and 3, in some embodiments, the number of the through openings 31 is less than the number of the air outlets 11.

Thus, the same port 31 can be communicated with a plurality of air outlets 11.

Specifically, the number of the air outlets 11 on the air outlet area 12 may be set to 8, and the number of the openings 31 on the rotary valve 30 may be set to 7. In the embodiment of the present application, the air outlets 11 correspond to the through holes 31 one-to-one, and the rotary valve 30 is not provided with the rear foot blowing through hole 31 corresponding to the rear foot blowing through hole 118. Thus, in different modes, the defrost port 317 may be communicated with the rear foot blowing opening 118 to achieve the air outlet function of the rear foot blowing opening 118.

Of course, in other embodiments, the number of the through openings 31 may be greater than or equal to the number of the air outlets 11.

Referring to fig. 2 and 3, in some embodiments, the outlet 11 and/or the port 31 are in the shape of a fan ring.

Thus, the plurality of outlets 11 and the plurality of through openings 31 can realize the air outlet function on the respective circumferences as much as possible, and cross communication does not occur between the outlets and the through openings.

Specifically, the first circle 51, the second circle 52 and the third circle 53 may be regarded as annular regions arranged at intervals from the center of the spherical surface to the outside, and the air outlet 11 and the through opening are parts of the annular regions, namely fan-shaped rings.

Of course, in other embodiments, the outlet 11 and the through opening 31 may have other shapes. For example, the outlet 11 has a fan-ring shape, and the through opening 31 has a rectangular, circular, trapezoidal, irregular shape, or the like. Alternatively, the outlet 11 may have a rectangular, circular, trapezoidal, irregular shape, or the like, and the port 31 may have a fan-ring shape. Alternatively, the outlet 11 may be rectangular, circular, trapezoidal, irregular, or the like, and the shape of the through opening 31 corresponds to the shape of the outlet 11 one by one.

Referring to fig. 1, in some embodiments, a seal 70 is disposed between the rotary valve 30 and the housing 10, and the seal 70 seals a gap between the rotary valve 30 and the housing 10.

Thus, the sealing member 70 prevents the rotary valve 30 from leaking between the casing 10 and the rotary valve to cause unnecessary wind loss, and also serves to isolate the temperature inside the casing 10 from leaking.

Specifically, the sealing member 70 may be a sealing sponge, a heat insulating cotton, or the like. The sealing member 70 is provided between the rotary valve 30 and the casing 10, and further, the sealing member 70 is provided between the rotary valve 30 and the tuyere region 12 of the casing 10. The sealing member 70 is provided with a plurality of air vents 71, and the plurality of air vents 71 correspond to the air outlets 11 one by one.

Referring to fig. 1, in some embodiments, the air conditioning box 100 includes a driving member 60 connected to the rotary valve 30, and the driving member 60 is used to drive the rotary valve 30 to rotate.

In this way, the driving member 60 can drive the rotary valve 30 to rotate to realize the opening and closing of each air outlet 11 and the switching between the plurality of modes.

Specifically, the driving member 60 may be a servo motor, which refers to an engine that controls the operation of mechanical elements in a servo system. The servo motor can control the speed and position accuracy accurately, and can convert the voltage signal into torque and rotating speed to drive a control object. The servo motor is divided into two types of direct current and alternating current, and is mainly characterized in that when the signal voltage is zero, the signal voltage has no autorotation phenomenon, and the rotating speed is reduced at a constant speed along with the increase of the torque. The driving component 60 can be disposed at the center of the hemispherical surface of the air inlet area 12, i.e., on the rotation axis Z of the rotary valve 30, and then the driving component 60 can precisely control the rotary valve 30 to rotate, so as to realize the communication between the air outlet 11 on the rotary valve 30 and the air inlet area 12 and the port 31.

Referring to fig. 7, the embodiment of the present application further provides a vehicle 200, where the vehicle 200 includes a vehicle body 220 and the air conditioning box 100 of any of the above embodiments, and the vehicle body 220 has a passenger compartment 210.

The front of the vehicle 200 has a certain accommodation space in which the air-conditioning box 100 can be installed, and the air blown by the air-conditioning box 100 is used to regulate the temperature in the passenger compartment 210, which is convenient for bringing a more comfortable riding environment to passengers.
