[0041] Embodiments of the present disclosure are described in detail below with reference to the accompanying drawings. The embodiments described below by reference to the accompanying drawings are exemplary and are intended to explain the present disclosure, and cannot be understood as a limitation of the present disclosure.

[0042] The static pressure box 100 of the embodiment of the present disclosure comprises a box 1 and a damper 2. The box 1 comprises a cavity 11, a vent 12, a first air outlet 131 and a second air outlet 132, the cavity 11 comprises a first passage 111 communicating with the first air outlet 131 and a second passage 112 communicating with the second air outlet 132, and the first passage 111 and the second passage 112 both communicate with the vent 12. The damper 2 is arranged in the cavity 11 and rotatably connected with the box 1 to open and close the first passage 111 and the second passage 112.

[0043] Specifically, as shown in Figure 1 and Figure 6 , the first air outlet 131 and the second air outlet 132 are arranged in the up-down direction, the first air outlet 131 is arranged at the upper end of the front side 14 of the box, the second air outlet 132 is arranged at the lower end of the front side 14 of the box, and the vent 12 is arranged at the rear side 15 of the box.

[0044] As shown in Figure 3 and Figure 8As shown, the first channel 111 is located above the second channel 112, the inlet end of the first channel 111 is in communication with the air vent 12, the outlet end of the first channel 111 is in communication with the first air outlet 131, the inlet end of the second channel 112 is in communication with the air vent 12, and the outlet end of the second channel 112 is in communication with the second air outlet 132.

[0045] The static pressure tank 100 of the embodiment of the present disclosure controls the outflow direction of the air conditioner by setting the damper 2 to open and close the first channel 111 and the second channel 112. When the first channel 111 and the second channel 112 are closed, part of the airflow in the cavity 11 flows out through the first channel 111 and the first air outlet 131, and another part of the airflow flows out through the second channel 112 and the second air outlet 132. When the first channel 111 and the second channel 112 are open, the airflow in the second channel 112 flows into the first channel 111 and merges with the airflow in the first channel 111, and then flows out through the first air outlet 131, or the airflow in the first channel 111 flows into the second channel 112 and merges with the airflow in the second channel 112, and then flows out through the second air outlet 132. Thus, the outflow direction of the air conditioner is controlled, the outflow effect is improved, and the user experience is improved.

[0046] In some embodiments, the air vent 12 includes a first air vent 121 and a second air vent 122, the first air vent 121 is in communication with the first channel 111, and the second air vent 122 is in communication with the second channel 112. The cavity 11 further includes a flow channel 113 in communication with the first channel 111 and the second channel 112, and the damper 2 is arranged in the flow channel 113.

[0047] Specifically, as shown in Figure 1 and Figure 2 The first air vent 121 and the second air vent 122 are arranged in the up-down direction and spaced apart, and the first air vent 121 is located above the second air vent 122. The airflow enters the first channel 111 through the first air vent 121 and enters the second channel 112 through the second air vent 122. The flow channel 113 extends in the up-down direction, the upper end of the flow channel 113 is in communication with the first channel 111, and the lower end of the flow channel 113 is in communication with the second channel 112. Through the arrangement of the flow channel 113, the airflow in the first channel 111 can flow to the second channel 112 through the flow channel 113, and the airflow in the second channel 112 can flow to the first channel 111 through the flow channel 113, thereby facilitating the control of the flow direction of the airflow.

[0048] In some embodiments, the damper 2 includes a first damper 21 and a second damper 22. The first damper 21 is located at one end of the flow channel 113 adjacent to the first channel 111 to connect and disconnect the first channel 111 and the flow channel 113. The second damper 22 is located at one end of the flow channel 113 adjacent to the second channel 112 to connect and disconnect the second channel 112 and the flow channel 113.

[0049] Specifically, such as Figures 2-5 As shown, the first damper 21 and the second damper 22 are arranged at intervals in the vertical direction. The first damper 21 is located above the second damper 22. The rear end of the first damper 21 is rotatably connected to the rear wall of the flow channel 113. When the front end of the first damper 21 is at the same height as the rear end of the first damper 21, the first damper 21 is closed, and the first channel 111 is disconnected from the flow channel 113. When the front end of the first damper 21 is lower than the rear end of the first damper 21, the first damper 21 is open, and the first channel 111 is connected to the flow channel 113. The rear end of the second damper 22 is rotatably connected to the rear wall of the flow channel 113. When the front end of the second damper 22 is at the same height as the rear end of the second damper 22, the second damper 22 is closed, and the second channel 112 is disconnected from the flow channel. When the front end of the second damper 22 is higher than the rear end of the second damper 22, the second damper 22 is open, and the second channel 112 is connected to the flow channel 113. The setting of the first damper 21 and the second damper 22 facilitates the connection and disconnection of the flow channel 113 with the first channel 111 and the second channel 112, thereby changing the airflow direction in the static pressure box 100.

[0050] When the circulation channel 113 is disconnected from the first channel 111 and the second channel 112, the airflow entering the first channel 111 through the first vent 121 flows out from the first air outlet 131, and the airflow entering the second channel 112 through the second vent 122 flows out from the second air outlet 132. When the circulation channel 113 is connected to the first channel 111 and the second channel 112, the airflow entering the first channel 111 through the first vent 121 can flow to the second channel 112 and flow out from the second air outlet 132, or the airflow entering the second channel 112 through the second vent 122 can flow to the first channel 111 and flow out from the first air outlet 131, thereby controlling the direction of airflow and facilitating the control of the air outlet direction of the air conditioner, thus improving the user experience.

[0051] In some embodiments, the cavity 11 includes a guide section 114 and a body section 115. The damper 2 is disposed in the body section 115. The body section 115 includes a first channel 111 and a second channel 112. The vent 12 is formed at one end of the guide section 114. The dimension of the guide section 114 in the height direction of the static pressure box 100 is smaller than the dimension of the body section 115 in the height direction of the static pressure box 100.

[0052] Specifically, as shown in Figures 7-11 the height direction of the static pressure box 100 is consistent with the up-down direction, the air guide section 114 and the body section 115 are arranged in sequence in the front-rear direction, the rear end of the air guide section 114 forms the air vent 12, the front end of the air guide section 114 communicates with the rear end of the body section 115, and the front end of the body section 115 communicates with the first air outlet 131 and the second air outlet 132.

[0053] By setting the size of the air guide section 114 in the up-down direction to be smaller than the size of the body section 115 in the up-down direction, the air guide section 114 is facilitated to accelerate and guide the airflow, the accelerated airflow is diffused in the body section 115, the speed of the airflow is reduced, and the uniformity and stability of the airflow in the static pressure box 100 are improved.

[0054] Optionally, the air guide section 114 is a plurality of air guide sections 114, the air vent 12 is a plurality of air vents 12, and the plurality of air vents 12 are arranged in one-to-one correspondence with the plurality of air guide sections 114, which can improve the uniformity of the airflow distribution into the cavity 11.

[0055] In some embodiments, the body section 115 includes a diffuser section 1151 and a pressure stabilizing section 1152, the diffuser section 1151 communicates with the air guide section 114 at an end away from the pressure stabilizing section 1152, the pressure stabilizing section 1152 communicates with the first air outlet 131 and the second air outlet 132 at an end away from the diffuser section 1151, and the size of the diffuser section 1151 in the height direction of the static pressure box 100 is smaller than the size of the pressure stabilizing section 1152 in the height direction of the static pressure box 100 and larger than the size of the air guide section 114 in the height direction of the static pressure box 100.

[0056] Specifically, as shown in Figures 6-7 the diffuser section 1151 and the pressure stabilizing section 1152 are arranged in sequence in the front-rear direction, the rear end of the diffuser section 1151 communicates with the front end of the air guide section 114, the front end of the diffuser section 1151 communicates with the rear end of the pressure stabilizing section 1152, and the front end of the pressure stabilizing section 1152 communicates with the first air outlet 131 and the second air outlet 132.

[0057] By setting the size of the diffuser section 1151 in the up-down direction to be larger than the size of the air guide section 114 in the up-down direction, the airflow is diffused in the diffuser section 1151, the speed of the airflow is reduced, and part of the dynamic pressure of the airflow becomes static pressure; by setting the size of the pressure stabilizing section 1152 in the up-down direction to be larger than the size of the diffuser section 1151 in the up-down direction, the speed of the airflow is further reduced in the pressure stabilizing section 1152, the maximization of static pressure is achieved, and the stability of the airflow is improved.

[0058] Optionally, a damper 2 is arranged in the constant pressure section 1152 for dividing the space in the constant pressure section 1152 into the first passage 111 and the second passage 112, and the damper 2 is rotatable relative to the cabinet 1 to open and close the first passage 111 and the second passage 112. The damper 2 extends in the front-rear direction, and the front end of the damper 2 is rotatably connected to the inner wall surface of the front side of the cabinet 1.

[0059] When the front end and the rear end of the damper 2 are at the same height, the damper 2 divides the space in the constant pressure section 1152 into the first passage 111 and the second passage 112 in the up-down direction, the first passage 111 is located above the second passage 112, and part of the airflow entering the cavity 11 through the air vent 12 flows out from the first air outlet 131 through the first passage 111, and the other part of the airflow flows out from the second air outlet 132 through the second passage 112. When the front end of the damper 2 is located above the rear end of the baffle, the first passage 111 and the second passage 112 are open, and the airflow entering the cavity 11 through the air vent 12 can flow out from the first passage 111 and the first air outlet 131, or flow out from the second passage 112 and the second air outlet 132.

[0060] In some embodiments, the static pressure box 100 further comprises a first air baffle 31 and a second air baffle 32, the first air baffle 31 is located at the first air outlet 131 and is rotatably connected to the cabinet 1 to open and close the first air outlet 131, and the second air baffle 32 is located at the second air outlet 132 and is rotatably connected to the cabinet 1 to open and close the second air outlet 132.

[0061] Specifically, as shown in Figure 2 and Figure 7 , the first air baffle 31 and the second air baffle 32 are arranged in the up-down direction, the first air baffle 31 is located above the second air baffle 32, and the arrangement of the first air baffle 31 and the second air baffle 32 facilitates the guidance of the airflow blown out of the first air outlet 131 and the second air outlet 132.

[0062] As shown in Figure 3 , the static pressure box 100 has a first state, in the first state, the first damper 21 closes the first passage 111 and the flow passage 113, the second damper 22 closes the second passage 112 and the flow passage 113, the first air baffle 31 opens the first air outlet 131, the second air baffle 32 opens the second air outlet 132, the airflow entering the first passage 111 through the first air vent 121 flows out from the first air outlet 131, and the airflow entering the second passage 112 through the second air vent 122 flows out from the second air outlet 132, thereby realizing the upper air outlet and the lower air outlet of the air conditioner.

[0063] As shown in Figure 4As shown, the static pressure box 100 has a second state. In the second state, the first damper 21 connects the first channel 111 and the circulation channel 113, the second damper 22 connects the second channel 112 and the circulation channel 113, the first air guide plate 31 closes the first air outlet 131, and the second air guide plate 32 opens the second air outlet 132. The airflow that enters the first channel 111 through the first ventilation port 121 enters the second channel 112 through the circulation channel 113 and merges with the airflow in the second channel 112 before flowing out from the second air outlet 132, realizing the downward air outlet of the air conditioner and achieving a carpet-like air supply effect.

[0064] like Figure 5 As shown, the static pressure box 100 has a third state. In the third state, the first damper 21 connects the first channel 111 and the circulation channel 113, the second damper 22 connects the second channel 112 and the circulation channel 113, the first air guide plate 31 opens the first air outlet 131, and the second air guide plate 32 closes the second air outlet 132. The airflow that enters the second channel 112 through the second ventilation port 122 enters the first channel 111 through the circulation channel 113 and merges with the airflow in the first channel 111 before flowing out from the first air outlet 131, realizing the upward air outlet of the air conditioner and achieving the effect of skylight-style air supply.

[0065] like Figure 8 As shown, the static pressure box 100 has a fourth state. In the fourth state, the damper 2 disconnects the first channel 111 and the second channel 112, the first air guide plate 31 opens the first air outlet 131, and the second air guide plate 32 opens the second air outlet 132. The airflow entering the cavity 11 through the ventilation port 12 is partially directed to the first channel 111 and flows out from the first air outlet 131 under the action of the damper 2, while the other part flows to the second channel 112 and flows out from the second air outlet 132, thus realizing the upper and lower air outlets of the air conditioner.

[0066] like Figure 9 As shown, in the fourth state, the first channel 111 and the second channel 112 can also be connected. Part of the airflow entering the cavity 11 through the vent 12 flows to the first channel 111 and flows out from the first air outlet 131, while the other part flows to the second channel 112 and flows out from the second air outlet 132.

[0067] like Figure 10 As shown, the static pressure box 100 has a fifth state. In the fifth state, the damper 2 connects the first channel 111 and the second channel 112, the first air guide plate 31 closes the first air outlet 131, and the second air guide plate 32 opens the second air outlet 132. The airflow enters the cavity 11 through the ventilation port 12. Since the first air guide plate 31 closes the first air outlet 131, the upper area of ​​the static pressure box 100 is in a high-pressure state, and the airflow will not flow upward. This allows the airflow to flow out through the second channel 112 and the second air outlet 132, realizing the downward airflow of the air conditioner and achieving a carpet-like air supply effect.

[0068] As shown in Figure 11 The static pressure box 100 has a sixth state, in which the damper 2 is open to the first passage 111 and the second passage 112, the first air deflector 31 is open to the first air outlet 131, the second air deflector 32 is closed to the second air outlet 132, and the airflow entering the cavity 11 through the air vent 12 cannot flow downward due to the closed second air outlet 132, so that the airflow flows out through the first passage 111 and the first air outlet 131, realizing the up air outlet of the air conditioner and achieving the sky curtain air supply effect.
