[0002] With economic development and rising living standards, people expect air conditioners to not only provide faster and more efficient cooling and heating, but also place increasing importance on the airflow experience. In current technology, the design of the air outlet structure of the indoor unit of wall-mounted air conditioners is inadequate, resulting in a limited airflow area and poor airflow performance and efficiency. CONTENTS OF THE PRESENT USE SAMPLE

[0003] The present utility model aims to solve one of the technical problems in the prior art, at least to a certain extent.

[0004] For this purpose, embodiments of the present utility model provide a housing component, wherein the housing component can increase the air supply area and improve the air supply effect and air supply efficiency.

DETAILED DESCRIPTION

[0019] Embodiments of the present utility model are described in detail below; examples of these embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and serve to illustrate the present utility model, but should not be interpreted as limiting it.

[0020] The housing component and the air conditioning system equipped with it in the embodiments of the present utility model are described below with reference to Fig. 1 to Fig. 4 described.

[0021] As in Fig. 2 and Fig. As shown in Figure 3, the housing component of the embodiments of the present utility model comprises a housing 1, an air outlet duct 2, and a wind turbine 3. An air inlet 11 is provided on the bottom wall surface of the housing 1, and an air outlet 12 is provided on the front wall surface of the housing 1. The air outlet duct 2 and the wind turbine 3 are both arranged in the housing 1, and the wind turbine 3 is arranged at one end of the air outlet duct 2 (the rear end of the air outlet duct 2), and the other end of the air outlet duct 2 (the front end of the air outlet duct 2) is connected to the air outlet 12. The air outlet duct 2 comprises a first air duct wall 21. One end of the first air duct wall 21 (the rear end of the first air duct wall 21) has a spiral groove surface 211, and the other end of the first air duct wall 21 (the front end of the first air duct wall 21) is connected to the upper edge of air outlet 12 connected.

[0022] In a projection surface orthogonal to the axis of the wind turbine 3, the angle between a first connecting line F1, which connects the tail end K1 of the spiral groove surface 211 with the axis center 01 of the wind turbine 3, and a vertically downward-pointing direction β1 is given by , where 50° ≤ β1 ≤ 120°. It is understood that the first connecting line F1 is tangent to the endpoint of the tail end K1 of the spiral groove surface 211, and a vertically downward-pointing line is drawn, originating from the axis center 01 of the wind turbine 3, where the angle between the first connecting line F1 and the vertical line is given by .

[0023] For example, β1 can be 50°, 70°, 80°, 90°, 100°, 110° or 120°.

[0024] It should be noted that the axis center 01 of the wind turbine 3 is the projection point of the rotation axis of the wind turbine 3 on the projection surface, orthogonal to the axis direction of the wind turbine 3. If the wind turbine 3 is cylindrical, the axis center 01 of the wind turbine 3 is the center of the circle on the projection surface of the wind turbine 3, which is perpendicular to the axial direction of the wind turbine 3.

[0025] The directions up-down, left-right and front-back of housing 1 correspond to those of the air conditioner after installation.

[0026] In the housing component of the embodiments of the present utility model, it is provided that by arranging the air outlet 12 on the front wall surface of the housing 1 and connecting the air outlet duct 2 to the air outlet 12, the problem of the airflow being blocked by wind at the ceiling is avoided compared to the solution "the air outlet is directed towards the top wall". This reduces the energy consumption of the air conditioning system and helps to distribute the airflow more evenly over a larger area in the room, thereby increasing the air supply area.

[0027] Furthermore, since the angle β1 between a first connecting line F1, which connects the rear end K1 of the spiral groove surface 211 with the axis center 01 of the wind turbine 3, and a vertically downward direction lies within the aforementioned area, the arrangement path of the air outlet duct 2 can be optimized to reduce the resistance of the airflow as it passes through the spiral groove surface 211 and to reduce the noise generated as the air flows through the spiral groove surface 211. Therefore, the housing component of the embodiments of the present utility model can increase the air supply area and improve the air supply effect and efficiency.

[0028] In relevant technology, at least part of the air outlet 12 of the air conditioner is located on the upper wall of the housing 1, and accordingly, the outlet end of the air outlet duct 2 generally also points upwards. As in Fig. As shown in Figure 2, the contour enclosed by the dashed line is the air outlet duct in the relevant technology. In the above solution, dust can easily enter air outlet duct 2 from air outlet 12, which can easily lead to dust accumulation at the air outlet position of air outlet duct 2. On the other hand, if the air conditioner is mounted on the ceiling in the above solution, the heat exchange airflow, since air outlet duct 2 blows the air upwards, will hit the upper wall of the room, resulting in increased energy consumption by the air conditioner. Furthermore, the heat exchange airflow circulates slowly in the room, affecting the air supply effect and efficiency of the air conditioner.

[0029] In the housing component of the embodiments of the present utility model, the air outlet duct 2 generally extends in a front-to-back direction, thus allowing the air outlet duct 2 to discharge the heat-exchanged airflow from the air outlet 12 at the front of the housing 1 in a back-to-front direction. This prevents dust from entering the air outlet duct 2 via the air outlet 12 and reduces the volume of the heat-exchange airflow flowing at the ceiling. This ensures that the majority of the heat-exchange airflow can flow evenly over a larger area of ​​the room, which has a positive effect on the air supply effect and efficiency.

[0030] It is understandable that the air outlet duct 2 in relevant technology (the one marked by the dashed line in Fig. The outline shown in Figure 2 is rotated clockwise by a preset angle, with the axis center 01 of the wind turbine 3 (i.e., the center of the circular cross-section of the wind turbine 3) serving as the center of rotation to obtain approximately a portion of the air outlet duct 2 of the present application. That is, P1 rotates to P1' and P2 rotates to P2'. Furthermore, the housing component of the embodiments of the present utility model can improve the air supply effect and contribute to noise reduction when the air outlet duct 2 directs the air, exhibiting a good noise reduction effect by extending P2', obtained by a clockwise rotation, forward by a predetermined distance (i.e., P2' is extended forward to P2").

[0031] As in Fig. As shown in Figure 2, the angle β1' of the air outlet duct 2 in the relevant technology is generally between 20° and 50°. The spiral groove surface 211 of the air outlet duct 2 in the relevant technology is rotated 20° to 100° clockwise forward around the center of axis 01 of the wind turbine 3 to approximate the position of the spiral groove surface 211 of the air outlet duct 2 of the present utility model. This can be adapted to the front air outlet structure of the air conditioning system of the present utility model. In other words, the difference between β1 and β1' is generally in the range of 20° to 100°.

[0032] The inventors of the present utility model have found through experimental investigations that by setting β1 to the above-mentioned size, the position of the snail throat surface 211 of the air outlet duct 2 can be optimized to reduce the noise generated by the air conditioning system when expelling air and to improve the air supply efficiency, and the air supply area is wider.

[0033] Optionally, the air outlet duct includes 2, as shown in Fig. 2 and Fig. Figure 3 shows a second air duct wall 22, wherein one end of the second air duct wall 22 has a helical tongue surface 221 and the other end of the second air duct wall 22 is connected to a lower edge of the air outlet 12, wherein in a projection surface orthogonal to the axis direction of the wind turbine 3 the angle between a second connecting line F2, which connects the tail end K3 of the helical tongue surface 221 with the axis center 01 of the wind turbine 3, and a perpendicular downward direction α1 is, where 45°≤α1≤105° applies.

[0034] For example, α1 can be 45°, 55°, 65°, 75°, 85°, 95° or 105°.

[0035] The inventors of the present utility model have found through experimental investigations that the position of the snail tongue surface 221 of the air outlet duct 2 can be optimized when α1 is set to the above size in order to improve the noise emission during wind removal from the air conditioner, increase the air supply efficiency and the air supply area is wider.

[0036] It is understandable that, as in Fig. As shown in Figure 2, the angle α1' of the air outlet duct 2 in the relevant technology is generally between 105° and 140°. The spiral tongue surface 221 of the air outlet duct 2 is rotated clockwise forward around the center of axis 01 of the wind turbine 3 in the relevant technology to obtain the position of the spiral tongue surface 221 of the air outlet duct 2 of the present utility model. This can be adapted to the front air outlet structure of the air conditioning system of the present utility model.

[0037] It should be noted that the tail end K1 of the snail throat surface 211 is the lower end of the snail throat surface 211. The head end K2 of the snail throat surface 211 is the upper end of the snail throat surface 211. Similarly, the tail end K3 of the snail tongue surface 221 is the lower end of the snail tongue surface 221. The head end K4 of the snail tongue surface 221 is the upper end of the snail tongue surface 221.

[0038] Using the example of the snail tongue surface 221, the calibration method of the “hedge end K3 of the snail tongue surface 221” consists of using the intersection of the straight line passing through the center of the circle of the wind turbine 3 and the lower end of the snail tongue surface 221 in the projection surface orthogonal to the axial direction of the wind turbine 3, i.e. the endpoint of the helix end K3 of the snail tongue surface 221.

[0039] The calibration method of the “head end K4 of the worm tongue surface 221” consists of using the intersection of the straight line passing through the center of the circle of the wind turbine 3 and the upper end of the worm tongue surface 221 in the projection surface orthogonal to the axial direction of the wind turbine 3, i.e. the endpoint of the head end K4 of the worm tongue surface 221.

[0040] In some embodiments, such as in Fig. As shown in Figure 3, it is provided that in the projection surface perpendicular to the axis direction of the wind turbine 3, the radius of the wind turbine 3 is R, wherein the tail end K1 of the spiral groove surface 211 is located below the axis center 01 of the wind turbine 3, the distance between the tail end K1 of the spiral groove surface 211 and the axis center 01 of the wind turbine 3 in the front-back direction of the housing 1 is L1, wherein the distance between the tail end K1 of the spiral groove surface 211 and the axis center 01 of the wind turbine 3 in the top-bottom direction of the housing 1 is H1, where R≤L1≤R+18mm and R / 6≤H1≤2R / 3 apply.

[0041] The housing component of the embodiments of the present utility model adjusts L1 and H1 to the above-mentioned size, which is slightly higher than the helical groove surface 211 of the original air outlet duct (such as air outlet duct 2 in Fig. 2) The inventors of the present utility model have found through experimental investigations that the air outlet path at the position of the snail throat surface 211 of the air outlet duct 2 can be optimized by adjusting L1 and H1 to the above-mentioned dimensions in order to improve the noise emission of the air conditioning system during wind discharge and to increase the air supply efficiency.

[0042] For example, L1 can be R, R+2 mm, R+4 mm, R+6 mm, R+8 mm, R+10 mm, R+12 mm, R+14 mm, R+16 mm, or R+18 mm. For example, H1 can be R / 6, R / 5, R / 4, R / 3, R / 2, or 2R / 3.

[0043] In a further development, in the projection surface perpendicular to the axis direction of the wind turbine 3, the radius of the wind turbine 3 is R, the distance between the head end K2 of the worm groove surface 211 and the axis center 01 of the wind turbine 3 in the front-back direction of the housing 1 is L2, and the distance between the head end K2 of the worm groove surface 211 and the axis center 01 of the wind turbine 3 in the top-bottom direction of the housing 1 is H2, where R≤L2≤R+10 mm and 0≤H2≤R / 3 apply.The inventors of the present utility model have found through experimental investigations that if L2 and H2 of the head end K2 of the spiral groove surface 211 lie within the above range, the air outlet path of the spiral groove surface 211 of the air outlet channel 2 can be optimized, this improves the noise emission of the air conditioning system during wind discharge, reduces the noise emission when the air flows through the spiral groove surface 211, improves the air supply efficiency and helps to reduce the resistance of the airflow when flowing through the spiral groove surface 211.

[0044] For example, L2 can be R, R+2 mm, R+4 mm, R+6 mm, R+8 mm, or R+10 mm. For example, H2 can be 0, R / 5, R / 4, and R / 3.

[0045] In some embodiments, such as in Fig. As shown in Figure 3, it is provided that in the projection surface perpendicular to the axis direction of the wind turbine 3 the radius of the wind turbine 3 is R, the distance between the tail end K3 of the worm tongue surface 221 and the axis center 01 of the wind turbine 3 in the front-back direction of the housing 1 is L3, and the distance between the tail end K3 of the worm tongue surface 221 and the axis center 01 of the wind turbine 3 in the top-bottom direction of the housing 1 is H3, where R≤L3≤R+12mm and 0≤H3≤4R / 5 apply.

[0046] The housing component of the embodiments of the present utility model adjusts L3 and H3 to the above-mentioned size, which is slightly lower than the snail tongue area 221 of the original air outlet duct (such as air outlet duct 2 in Fig. 2) The inventors of the present utility model have found through experimental investigations that the air outlet path at the position of the snail tongue surface 221 of the air outlet duct 2 can be optimized by adjusting L3 and H3 to the above-mentioned dimensions in order to improve the noise emission of the air conditioning system during wind discharge and to increase the air supply efficiency.

[0047] For example, L3 can be R, R+2 mm, R+4 mm, R+6 mm, R+8 mm, R+10 mm, or R+12 mm. H3 can be 0, R / 5, 2R / 5, 3R / 5, or 4R / 5.

[0048] Optionally, the tail end K3 of the worm tongue surface 221 is located in a projection surface perpendicular to the axial direction of the wind turbine 3 above the axis center 01 of the wind turbine 3, wherein the distance between the tail end K3 of the worm tongue surface 221 and the axis center 01 of the wind turbine 3 in the top-bottom direction of the housing 1 is H3, where 0 ≤ H3 ≤ 4R / 5. For example, H3 can be 0, R / 5, 2R / 5, 3R / 5, or 4R / 5.

[0049] In other examples, the trailing end K3 of the worm tongue surface 221 is located below the axis center 01 of the wind turbine 3, and the distance between the trailing end K3 of the worm tongue surface 221 and the axis center 01 of the wind turbine 3 in the top-bottom direction of the housing 1 is H3, where 0 ≤ H3 ≤ 3R / 4. For example, H3 can be 0, R / 4, 2R / 4, or 3R / 4.

[0050] In other words, the tail end K3 of the snail tongue surface 221 can float in the horizontal plane passing through the axis center 01 of the wind turbine 3 by a preset distance (0 to 4R / 5) above the horizontal plane or by a distance (0 to 3R / 4) below the horizontal plane.

[0051] The inventors of the present utility model have discovered through experimental investigations that the air outlet path of the air outlet duct 2 can be optimized by adjusting H3 to the above-mentioned parameters in order to improve the noise level of the air conditioning system during wind discharge and to increase the air supply efficiency.

[0052] In some embodiments, such as in Fig. As shown in Figure 4, it is provided that in a projection surface perpendicular to the axis direction of the wind turbine 3, the head end K4 of the worm tongue surface 221 is located above the axis center 01 of the wind turbine 3, the distance between the head end K4 of the worm tongue surface 221 and the axis center 01 of the wind turbine 3 in the front-back direction of the housing 1 is L4, and the distance between the head end K4 of the worm tongue surface 221 and the axis center 01 of the wind turbine 3 in the top-bottom direction of the housing 1 is H4, where 3R / 4≤L4≤3R / 4 +20mm and R / 4≤H4≤3R / 4 apply.

[0053] For example, L4 can be 3R / 4, 3R / 4+2mm, 3R / 4+4mm, 3R / 4+6mm, 3R / 4+8mm, 3R / 4+12mm, 3R / 4+14mm, 3R / 4+16mm, 3R / 4+18mm, 3R / 4+20mm. For example, H4 can be R / 4, R / 2 or 3R / 4.

[0054] The inventors of the present utility model have found through experimental investigations that the structure of the air outlet channel 2 can be designed more effectively if L4 and H4 of the head end K4 of the spiral tongue surface 221 are located within the above area, which has a positive effect on reducing the resistance of the airflow when passing through the spiral tongue surface 221 and on reducing the noise when the air flows through the spiral tongue surface 221.

[0055] Optionally, 45 mm ≤ R ≤ 65 mm. For example, R can be 45 mm, 50 mm, 55 mm, or 65 mm. The inventors of the present utility model have found through experimental investigations that the size of the air conditioner can be reduced while simultaneously ensuring good air supply efficiency and effect when the fan wheel assumes the aforementioned radius size. This results in a thinner and lighter overall machine structure and lower energy consumption.

[0056] In some embodiments, such as in the Fig. 3 and Fig. As shown in Figure 4, the gap between the wind turbine 3 and one of the auger throat surface 211 or the auger tongue surface 221 is W, where 1 mm ≤ W ≤ 10 mm. W can be 1 mm, 3 mm, 5 mm, 7 mm, 8 mm, or 10 mm. This increases the pressure head performance of the fan and improves the vibration and noise reduction effect of the air conditioner.

[0057] For example, the spiral groove surface 211 is spaced away from the wind turbine 3 along the radial direction of the wind turbine 3, and the gap is W in the direction extending from the rear end K1 of the spiral groove surface 211 to the head end K2 of the spiral groove surface 211 (as in the direction from bottom to top in Fig. (as shown in Figure 2) the gap W between the snail throat surface 211 and the wind turbine 3 gradually becomes smaller.

[0058] For example, the snail tongue surface 221 is spaced away from the wind turbine 3 along the radial direction of the wind turbine 3 and the gap is W.

[0059] In some embodiments, such as in the Fig. 3 and Fig. As shown in Figure 4, the first air duct wall 21 further comprises a first air guide surface 212 and an extension surface 213, wherein one end of the first air guide surface 212 is connected to the spiral groove surface 211 and the other end of the first air guide surface 212 is connected to one end of the extension surface 213 and the other end of the extension surface 213 is connected to the upper edge of the air outlet 12, wherein the extension surface 213 extends along the front-to-back direction of the housing 1, wherein the distance between the first air guide surface 212 and the wind turbine 3 gradually increases in the direction from back to front of the housing 1.

[0060] It is understandable that the first air guide surface 212 is an arc-shaped surface; in the direction from back to front, the distance between the arc-shaped surface and the wind turbine 3 gradually increases and smoothly transitions into the extension surface 213, thereby improving the flow guidance effect of the first air duct wall 21, reducing the resistance of the airflow and lowering energy consumption.

[0061] Since the extension surface 213 also extends along the front-to-back direction of the housing 1, the extension surface 213 can direct the airflow after heat exchange from the air outlet 12 at the front of the housing 1 in the direction from back to front, which has a positive effect on improving the air supply effect and air supply efficiency.

[0062] In some embodiments, such as in the Fig. 3 and Fig. As shown in Figure 4, the air outlet duct 2 comprises a second air duct wall 22, the second air duct wall 22 comprises a spiral tongue surface 221 and a second air guide surface 222, the spiral tongue surface 221 is spaced radially from the wind turbine 3, one end of the second air guide surface 222 is connected to the spiral tongue surface 221 and the other end of the second air guide surface 222 is connected to the lower edge of the air outlet 12, the extension surface 213 and the second air guide surface 222 are arranged relative to each other along the top-bottom direction of the housing 1, the second air guide surface 222 gradually extending downwards in the rear-to-front direction.

[0063] Since the second air guide surface 222 slopes downwards from back to front, a portion of the blown airflow can flow downwards, resulting in a more uniform temperature in the upper and lower regions of the room. Furthermore, the housing component of the embodiments of the present utility model can increase the blowing distance based on blowing at a large angle by adjusting the second air guide surface 222 to the aforementioned structure, thus ensuring better air supply performance from the air conditioner.

[0064] As in Fig.As shown in Figure 1, the air conditioning system of a further embodiment of the present utility model comprises a heat exchanger 4 and a housing component, wherein the housing component is the housing component of the present utility model and the heat exchanger 4 is arranged in the housing 1 and is located on the underside of the fan 3. Specifically, the heat exchanger 4 is generally V-shaped, the fan 3 is arranged in the upper region of the V-shaped structure of the heat exchanger 4, and the air inlet 11 is arranged opposite the lower wall surface of the heat exchanger 4 in order to exchange heat for the airflow entering the housing 1.

[0065] In the air conditioning system of the embodiments of the present utility model, it is provided that by arranging the air outlet 12 on the front wall surface of the housing 1 and connecting the air outlet duct 2 with the air outlet 12, the problem of the airflow being blocked by wind at the ceiling is avoided compared to the solution "the air outlet 12 is directed towards the top wall". This reduces the energy consumption of the air conditioning system and helps to distribute the airflow more evenly over a larger area in the room, thereby increasing the air supply area.Furthermore, since the angle β1 between a first connecting line F1, which connects the rear end K1 of the spiral groove surface 211 with the axis center 01 of the wind turbine 3, and a vertically downward direction lies within the aforementioned area, the arrangement path of the air outlet duct 2 can be optimized to reduce the resistance of the airflow as it passes through the spiral groove surface 211 and to reduce the noise generated as the air flows through the spiral groove surface 211. Therefore, the housing component of the embodiments of the present utility model can increase the air supply area and improve the air supply effect and efficiency.
