Detailed Implementation

[0031] Embodiments of this disclosure are described in detail below, with examples of these embodiments illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this disclosure, and should not be construed as limiting it.

[0032] The air conditioner 100 of this embodiment includes an air conditioner body 1 and an axial flow fan 2. The air conditioner body 1 has a chamber 11, an air inlet 12, and an air outlet 13. Both the air inlet 12 and the air outlet 13 are connected to the chamber 11. The air inlet 12 is located at at least one end of the air conditioner body 1 in its length direction. The axial flow fan 2 is disposed in the chamber 11, and the axial direction of the axial flow fan 2 is arranged perpendicular to the length direction of the air conditioner body 1.

[0033] Specifically, such as Figures 1-3 As shown, the length direction of the air conditioner body 1 is consistent with the left and right direction. The air inlet 12 is located at the left end of the air conditioner body 1, and the external airflow enters the cavity 11 through the left end air inlet 12; or, the air inlet 12 is located at the right end of the air conditioner body 1, and the external airflow enters the cavity 11 through the right end air inlet 12; or, the air inlet 12 is located at both the left and right ends of the air conditioner body 1, and the external airflow enters the cavity 11 through both the left end air inlet 12 and the right end air inlet 12.

[0034] The axial direction of the axial fan 2 is consistent with the front and rear direction. The air outlet 13 is located on the front side of the air conditioner body 1. The rear end of the axial fan 2 is the air inlet of the axial fan 2 and is arranged adjacent to the air inlet 12. The front end of the axial fan 2 is the air outlet of the axial fan 2 and is arranged adjacent to the air outlet 13. Under the action of the axial fan 2, the external airflow enters the chamber 11 from the left and / or right air inlet 12 and is blown out from the front air outlet 13.

[0035] Optionally, one or more axial flow fans 2 can be provided. When there are multiple axial flow fans 2, the multiple axial flow fans 2 are arranged at intervals in the left and right directions. For example, there are three axial flow fans 2.

[0036] Optionally, the air conditioner 100 also includes a mounting bracket 7 for mounting the axial fan 2 on the air conditioner body 1.

[0037] The air conditioner 100 of this embodiment provides an air inlet 12 at at least one end of the air conditioner body 1 along its length, and an axial flow fan 2 is provided in the chamber 11 with the axis of the axial flow fan 2 perpendicular to the length of the air conditioner body 1. This allows the airflow entering the chamber 11 from the air inlet 12 to flow along the axis of the axial flow fan 2 under its action. Compared to the method of air intake from the rear of the air conditioner body 1, this embodiment of the present invention can achieve wall mounting of the air conditioner 100. Moreover, compared to the method of air intake from the top of the air conditioner, the distance between the air inlet 12 and the air outlet 13 in this embodiment of the present invention is relatively far, which can avoid airflow short-circuiting, improve the air outlet effect of the air conditioner 100, and improve user comfort.

[0038] In some embodiments, the air conditioner body 1 includes an outer frame 14 and a static pressure box 15. The static pressure box 15 is disposed inside the outer frame 14, and the rear side 151 of the static pressure box and the outer frame 14 define a chamber 11. An air outlet 13 is disposed on the front side 152 of the static pressure box. The static pressure box 15 includes a cavity 153 communicating with the air outlet 13. An axial flow fan 2 is disposed inside the cavity 153. The rear side 151 of the static pressure box is provided with a vent 1511, which communicates with the chamber 11 and the cavity 153.

[0039] Specifically, such as Figures 1-5 As shown, the plenum chamber 15 is located on the front side of the outer frame 14. The rear side 151 of the plenum chamber and the inner wall of the outer frame 14 define a chamber 11. The front side 152 of the plenum chamber forms the front side of the air conditioner body 1. The air inlet 12 is located at the left and / or right end of the outer frame 14, and the axial flow fan 2 is located inside the cavity 153 of the plenum chamber 15. External airflow enters the cavity 11 through the air inlet 12, enters the cavity 153 through the vent 1511 of the plenum chamber 15, and is then blown out from the air outlet 13. By setting up the plenum chamber 15, part of the dynamic pressure of the airflow can be converted into static pressure, improving the uniformity of the airflow.

[0040] In some embodiments, such as Figures 2-3 As shown, the axial flow fan 2 is positioned near the vent 1511, allowing the axial flow fan 2 to directly drive the airflow in the chamber 11 through the vent 1511 into the cavity 153 of the static pressure box 15. This facilitates the rapid stabilization of the airflow in the cavity 153 to form a uniform static pressure airflow, thereby improving the uniformity of the airflow from the air conditioner 100.

[0041] In some embodiments, the cavity 153 includes a guide section 1531 and a body section 1532. The dimension of the guide section 1531 in the height direction of the air conditioning body 1 is smaller than the dimension of the body section 1532 in the height direction of the air conditioning body 1. An axial flow fan 2 is disposed in the guide section 1531. A vent 1511 is formed at the end of the guide section 1531 away from the body section 1532. An air outlet 13 is connected to the body section 1532.

[0042] Specifically, such as Figure 3 and Figure 5 As shown, the height of the air conditioner body 1 is consistent with the vertical direction. The air guide section 1531 and the body section 1532 are arranged sequentially in the front-to-back direction. The rear end of the air guide section 1531 forms a vent 1511. The front end of the air guide section 1531 is connected to the rear end of the body section 1532. The front end of the body section 1532 is connected to the air outlet 13.

[0043] By setting the vertical dimension of the air guide section 1531 to be smaller than that of the main body section 1532 in the vertical direction, the air guide section 1531 can accelerate and guide the airflow. The accelerated airflow diffuses in the main body section 1532, and the airflow speed is reduced, which helps to improve the uniformity and stability of the airflow in the static pressure box 15.

[0044] Optionally, there are multiple air guide sections 1531 and multiple ventilation openings 1511. The multiple air guide sections 1531 are arranged at intervals in the left and right directions, and the multiple ventilation openings 1511 are set one-to-one with the multiple air guide sections 1531. Each air guide section 1531 is equipped with an axial flow fan 2 to improve the uniformity of airflow distribution in the cavity 153.

[0045] In some embodiments, the dimension of the air guide section 1531 in the height direction of the air conditioner body 1 is L5, and the dimension of the air inlet 12 in the height direction of the air conditioner body 1 is L6, with L5 / L6 being 0.3-0.4. When the value of L5 / L6 is too small, the air intake area of ​​the air inlet 12 is relatively large, and the dimension of the air conditioner 100 in the vertical direction increases. Since the dimension of the air guide section 1531 in the vertical direction is relatively small, the increase in airflow into the static pressure box 15 is not significant. When the value of L5 / L6 is too large, the air intake area of ​​the air inlet 12 is relatively small, the airflow into the chamber 11 is less, the air intake volume of the axial fan 2 decreases, and the air volume of the air conditioner 100 is affected. By limiting the value of L5 / L6, the air intake area of ​​the air conditioner 100 is matched with the performance of the axial fan 2, thereby improving the performance of the air conditioner 100.

[0046] For example, L5 / L6 is 0.3, 0.35, 0.37, and 0.4. In this embodiment, it is 0.35.

[0047] In some embodiments, the body segment 1532 includes a diffuser segment 15321 and a stabilizing segment 15322 connected in sequence. The end of the diffuser segment 15321 away from the stabilizing segment 15322 is connected to the air guide segment 1531, and the end of the stabilizing segment 15322 away from the diffuser segment 15321 is connected to the air outlet 13. The dimension of the diffuser segment 15321 in the height direction of the air conditioner body 1 is smaller than the dimension of the stabilizing segment 15322 in the height direction of the air conditioner body 1, and the dimension of the diffuser segment 15321 in the height direction of the air conditioner body 1 is larger than the dimension of the air guide segment 1531 in the height direction of the air conditioner body 1.

[0048] Specifically, such as Figure 3 and Figure 5 As shown, the diffuser section 15321 and the pressure stabilizing section 15322 are arranged sequentially in the front-to-back direction. The rear end of the diffuser section 15321 is connected to the front end of the air guide section 1531, the front end of the diffuser section 15321 is connected to the rear end of the pressure stabilizing section 15322, and the front end of the pressure stabilizing section 15322 is connected to the air outlet 13.

[0049] By setting the vertical dimension of the diffuser section 15321 to be larger than that of the guide section 1531, the airflow diffuses in the diffuser section 15321, the airflow velocity decreases, and part of the dynamic pressure of the airflow becomes static pressure. By setting the vertical dimension of the pressure stabilizing section 15322 to be larger than that of the diffuser section 15321, the airflow velocity is further reduced in the pressure stabilizing section 15322, thereby maximizing the static pressure and improving the stability of the airflow.

[0050] In some embodiments, such as Figure 3 As shown, the air conditioner 100 also includes a heat exchanger 3, which is disposed within a diffuser section 15321. The airflow velocity is reduced within the diffuser section 15321. By placing the heat exchanger 3 within the diffuser section 15321, the airflow can fully contact the heat exchanger 3, thereby improving the heat exchange efficiency.

[0051] In some embodiments, the air conditioner 100 further includes a splitter plate 4, which is disposed in the pressure stabilizing section 15322 to divide the space in the pressure stabilizing section 15322 into a first channel 1533 and a second channel 1534. The splitter plate 4 is rotatable relative to the static pressure box 15 to open and close the first channel 1533 and the second channel 1534.

[0052] Specifically, such as Figure 3As shown, the air distribution plate 4 extends in the front-to-back direction. The front end of the air distribution plate 4 is rotatably connected to the inner wall of the static pressure box 15. When the front end and the rear end of the air distribution plate 4 are at the same height, the air distribution plate 4 divides the space in the pressure stabilizing section 15322 into a first channel 1533 and a second channel 1534 in the vertical direction. The first channel 1533 is located above the second channel 1534. When the front end of the air distribution plate 4 is located above the rear end of the air distribution plate 4, the first channel 1533 and the second channel 1534 are connected.

[0053] Optionally, the front end of the air distribution plate 4 is at the same height as the center of the axial flow fan 2, and the rear end of the air distribution plate 4 can extend into the diffuser section 15321 and be arranged at intervals with the heat exchanger 3 in the front-to-back direction.

[0054] In some embodiments, such as Figure 3 As shown, the dimension of heat exchanger 3 in the height direction of air conditioner body 1 is L8, and L5 / L8 is 0.5-0.7. When the value of L5 / L8 is small, the airflow through the air guide section 1531 is small, the airflow velocity on the surface of heat exchanger 3 is uneven, and the heat exchange efficiency is low. When the value of L5 / L8 is large, the airflow through the air guide section 1531 is large, and the heat exchange capacity of heat exchanger 3 is insufficient. By limiting the ratio of L5 / L8, it is ensured that heat exchanger 3 can fully exchange heat with the airflow while improving the heat exchange efficiency of heat exchanger 3.

[0055] For example, L5 / L8 is 0.5, 0.6, or 0.7. In this embodiment, it is 0.6.

[0056] In some embodiments, such as Figure 3 As shown, the distance between the axial fan 2 and the heat exchanger 3 in the front-to-back direction is L7, which is 80mm-100mm. By limiting L7, we avoid the situation where L7 is too small, which would result in an excessively small distance between the axial fan 2 and the heat exchanger 3, increasing the noise from the airflow blowing the fins of the heat exchanger 3. At the same time, we avoid the situation where the distance between the axial fan 2 and the heat exchanger 3 is too large, which would increase the airflow resistance and reduce the airflow rate.

[0057] In some embodiments, the wall of the cavity 153 includes a connecting wall 1535 connecting the air guide section 1531 and the diffuser section 15321. The dimension of the connecting wall 1535 in the height direction of the air conditioner body 1 is L3, and the dimension of the diffuser section 15321 in the front-rear direction of the air conditioner body 1 is L4, and L3 / L4 is 1-1.2.

[0058] Specifically, such as Figure 3As shown, the air conditioner 100 also includes a water collection tray 8, which is located within the diffuser section 15321 and below the heat exchanger 3. The dimensions of the water collection tray 8 in the front-to-back direction are the same as those of the diffuser section 15321 in the front-to-back direction. By limiting the ratio of L3 / L4, it is avoided that when L3 / L4 is small, the dimensions of the water collection tray 8 in the front-to-back direction are relatively large, which increases the airflow resistance. At the same time, it is avoided that when L3 / L4 is large, the dimensions of the water collection tray 8 in the front-to-back direction are small, and the dimensions of the diffuser section 15321 in the front-to-back direction are small, resulting in insufficient pressure stabilization distance and increased noise.

[0059] For example, the values ​​of L3 / L4 can be 1, 1.1, or 1.2. In this embodiment, it is 1.1.

[0060] In some embodiments, the air outlet 13 includes a first air outlet 131 and a second air outlet 132. The first air outlet 131 is located at the upper end of the front side of the air conditioner body 1, and the second air outlet 132 is located at the lower end of the front side of the air conditioner body 1.

[0061] Specifically, such as Figures 1-3 As shown, the first air outlet 131 is connected to the first channel 1533, and the second air outlet 132 is connected to the second channel 1534. By setting the first air outlet 131 and the second air outlet 132, the air conditioner 100 can achieve air outlet at the top and air outlet at the bottom.

[0062] Compared to the air intake method in related technologies where the air inlet 12 is located on the upper and / or lower side of the air conditioner body 1, the airflow from the first air outlet 131 and the second air outlet 132 can easily enter the cavity 11 through the air inlet 12, causing the airflow to short-circuit. In this embodiment, by placing the air inlet 12 on the left or right side of the air conditioner housing, the distance between the air inlet 12 and the air outlet 13 is increased, thus avoiding the airflow short-circuiting.

[0063] In some embodiments, the air conditioner 100 further includes a first air guide plate 51 and a second air guide plate 52. The first air guide plate 51 is disposed at the first air outlet 131 to open and close the first air outlet 131, and the second air guide plate 52 is disposed at the second air outlet 132 to open and close the second air outlet 132.

[0064] Specifically, such as Figures 1-3 As shown, the first air guide plate 51 and the second air guide plate 52 are arranged at intervals in the vertical direction. The first air guide plate 51 is located above the second air guide plate 52. The arrangement of the first air guide plate 51 and the second air guide plate 52 facilitates the guidance of the airflow blown out from the first air outlet 131 and the second air outlet 132.

[0065] like Figure 6As shown, the air conditioner 100 has a first state. In the first state, the first air guide plate 51 opens the first air outlet 131, and the second air guide plate 52 opens the second air outlet 132. The external airflow enters the cavity 11 through the air inlet 12 and enters the cavity 153 through the vent 1511 to exchange heat with the heat exchanger 3. When the first channel 1533 and the second channel 1534 are disconnected, the airflow after heat exchange is directed by the air distribution plate 4. Part of the airflow flows to the first channel 1533 and flows out through the first air outlet 131, and the other part flows to the second channel 1534 and flows out through the second air outlet 132, thereby realizing the upper and lower air outlets of the air conditioner 100.

[0066] like Figure 7 As shown, in the first state, the first channel 1533 and the second channel 1534 can also be connected. Part of the heat-exchanged airflow flows to the first channel 1533 and flows out through the first air outlet 131, while the other part flows to the second channel 1534 and flows out through the second air outlet 132.

[0067] like Figure 8 As shown, the air conditioner 100 has a second state. In the second state, the first air guide plate 51 opens the first air outlet 131, the second air guide plate 52 closes the second air outlet 132, the first channel 1533 and the second channel 1534 are connected, the external airflow enters the chamber 11 through the air inlet 12 and enters the cavity 153 through the vent 1511 to exchange heat with the heat exchanger 3. Since the second air guide plate 52 closes the second air outlet 132, the lower area of ​​the static pressure box 15 is in a high-pressure state, and the airflow will not flow downward. The airflow after heat exchange flows out from the first air outlet 131, realizing the upward air outlet of the air conditioner 100 and achieving the effect of skylight-style air supply.

[0068] like Figure 9 As shown, the air conditioner 100 has a third state. In the third state, the first air guide plate 51 closes the first air outlet 131, the second air guide plate 52 opens the second air outlet 132, the first channel 1533 and the second channel 1534 are connected, the external airflow enters the cavity 11 through the air inlet 12 and enters the cavity 153 through the vent 1511 to exchange heat with the heat exchanger 3. Since the first air guide plate 51 closes the first air outlet 131, the upper area of ​​the static pressure box 15 is in a high-pressure state, and the airflow will not flow upward. The airflow after heat exchange flows out from the second air outlet 132, realizing the downward air outlet of the air conditioner 100 and achieving a carpet-like air supply effect.

[0069] In some embodiments, the dimension of the first air outlet 131 or the second air outlet 132 in the height direction of the air conditioner body 1 is L9, the height of the air conditioner body 1 is L10, and L9 / L10 is 0.1-0.5. By limiting the value of L9 / L10, it is avoided that if the value of L9 / L10 is too small, the air outlet area of ​​the air outlet 13 will be too small, the air outlet resistance will increase, and the air volume will decrease. At the same time, it is avoided that if the value of L9 / L10 is too large, the air outlet area of ​​the air outlet 13 will be too large, resulting in insufficient static pressure and affecting the air delivery distance of the air conditioner 100.

[0070] For example, L9 / L10 is 0.1, 0.2, 0.3, and 0.5. In this embodiment, it is 0.2.

[0071] In some embodiments, such as Figures 1-3 As shown, the air conditioner 100 also includes an air inlet grille 6. The air inlets 12 are located at both ends along the length of the air conditioner body 1, and the air inlet grille 6 is located at the air inlets 12. The air inlet grille 6 facilitates the guidance of airflow while preventing foreign objects from entering the chamber 11 through the air inlets 12, thus improving safety.

[0072] In some embodiments, such as Figure 3 As shown, the distance between the front edge of the air inlet 12 and the rear side of the chamber 11 is L1, and the distance between the rear side of the static pressure box 151 and the rear side of the chamber 11 is L2, and L2 ≥ L1. By limiting the relationship between L1 and L2, sufficient air intake area is ensured while avoiding the front end of the air inlet 12 being located at the front end of the air guide section 1531, which would affect smooth air intake.

[0073] Optionally, L2 and L1 can be set to be the same.

[0074] In some embodiments, the axis of the axial fan 2 intersects the axis of the air inlet 12. The center of the air inlet 12 in the vertical direction is at the same height as the axis of the axial fan 2, ensuring symmetrical airflow in the vertical direction and reducing airflow noise.
