[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. 1 to 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, 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, wherein one 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 is connected to an upper edge of the air outlet 12, wherein the spiral groove surface 211 is spaced apart from the wind turbine 3 along the radial direction of the wind turbine 3.

[0022] On the projection surface perpendicular to the axial direction, the radius of the wind turbine 3 R is and the distance between the rear end K1 of the snail throat surface 211 and the axis center 01 of the wind turbine 3 in the front-back direction of the housing 1 is L1, where R≤L1≤R+12mm applies.

[0023] It should be noted that the radius of wind turbine 3 is the radius of rotation of wind turbine 3. The center of the axis of wind turbine 3 is the projection point of the axis of rotation of wind turbine 3 on the projection surface orthogonal to the axial direction of wind turbine 3. If wind turbine 3 is cylindrical, the center of the axis of wind turbine 3 is the center of the circle of the projection surface of wind turbine 3 that is perpendicular to the axial direction of wind turbine 3.

[0024] The directions up-down, left-right and front-back of housing 1 correspond to those of the air conditioner after installation.

[0025] 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.

[0026] Furthermore, by setting the distance L1 between the rear end K1 of the spiral groove surface 211 and the axis center 01 of the wind turbine 3 in the front-to-back direction of the housing 1 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 airflow passes 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.

[0027] In relevant technology, as in Fig. Figure 4 shows that at least part of the air conditioner's air outlet is located on the top wall of the housing, and accordingly, the outlet end of the air duct generally also points upwards. With the above solution, dust can easily enter the air duct from the air outlet, which can easily lead to dust accumulation at the air outlet position. On the other hand, if the air conditioner is ceiling-mounted in the above solution, the heat exchange airflow, since the air outlet duct blows 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.

[0028] 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 through 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 in the room, which has a positive effect on the air supply effect and efficiency.

[0029] For example, L1 can be R, R+2 mm, R+4 mm, R+6 mm, R+8 mm, R+10 mm or R+12 mm.

[0030] The housing component of the embodiments of the present utility model adjusts L1 to the above-mentioned size, which is slightly higher than the helical groove surface 211 of the original air outlet duct (such as the air outlet duct 2 in Fig. 4) Specifically, the range of values ​​for L1' of the air outlet duct in relevant technology lies between R / 3 and 2R / 3, while the range of values ​​for L1 in the embodiments of the present utility model lies between R and R+12 mm. The inventors of the present utility model have found through experimental investigations that by setting L1 to the aforementioned value, the air outlet path 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.

[0031] Optionally, as in Fig. 2 and Fig. Figure 3 shows that on the projection surface perpendicular to the axial direction of the wind turbine 3, the tail end K1 of the spiral groove surface 211 is located below the axis center 01 of the wind turbine 3. In other words, in a horizontal plane passing through the axis center 01 of the wind turbine 3, the tail end K1 of the spiral groove surface 211 is located below the horizontal plane.

[0032] It should be noted that the tail end K1 of the spiral groove surface 211 is the lower end of the spiral groove surface 211. The head end K2 of the spiral groove surface 211 is the upper end of the spiral groove surface 211. The spiral groove surface 211 is located at the junction between the air outlet duct 2 and the air inlet duct, and the tail end K1 of the spiral groove surface 211 is closer to the air inlet duct than the head end K2 of the spiral groove surface 211.

[0033] The calibration method of the “hedge end K1 of the spiral groove surface 211” 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 spiral groove surface 211 on the projection surface orthogonal to the axial direction of the wind turbine 3, i.e. the endpoint of the hedge end K1 of the spiral groove surface 211.

[0034] The calibration method of the “head end K2 of the spiral groove surface 211” 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 spiral groove surface 211 on the projection surface orthogonal to the axial direction of the wind turbine 3, i.e. the endpoint of the head end K2 of the spiral groove surface 211.

[0035] As in Fig. As shown in Figure 2, 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 / 3 ≤ H1 ≤ 2R / 3. For example, H1 can be R / 3, R / 2, or 2R / 3. The housing component of the embodiments of the present utility model adjusts H1 to the aforementioned size, which is slightly higher than the original air outlet duct 2 (such as the air outlet duct 2 in Figure 2). Fig. 2) The inventors of the present utility model have found through experimental investigations that by adjusting H1 to the above-mentioned size, the air outlet path of the air outlet duct 2 can be optimized in order to reduce the noise generated by the air conditioning system when expelling air and to improve the air supply efficiency.

[0036] For easier understanding, a coordinate system is created with the axis center 01 of the wind turbine 3 as the origin point, the vertical upward direction as the positive direction of the Y-axis and the horizontal forward direction as the positive direction of the X-axis.

[0037] As in Fig. As shown in Figure 2, the coordinate point (L1, H1) of the rear end K1 of the spiral groove surface 211 of the embodiments of the present utility model is: (-R-12mm to -R, -2R / 3 to -R / 3). As shown in Fig. As shown in Figure 4, when solving the air outlet duct (before optimization) in the relevant technique, the coordinate point (L1' , H1') of the tail end K1 of the snail throat surface 211 is: (-2R / 3 to -R / 3, -R-7 mm to - R+7 mm).

[0038] The inventors of the present utility model have found through experimental investigations that if the coordinate point (L1, H1) lies within the range of (-R-12mm to -R, - 2R / 3 to -R / 3), the arrangement path of the air outlet duct 2 can be optimized to reduce the resistance of the airflow as it flows through the spiral groove surface 211, and to reduce the noise as the airflow flows through the spiral groove surface 211, and thereby significantly improving the air supply efficiency.

[0039] In some embodiments, such as in Fig. As shown in Figure 2, it is provided that in a projection surface perpendicular to the axial direction of the wind turbine 3, the distance between the head end K2 of the worm throat surface 211 and the axis center 01 of the wind turbine 3 in the front-back direction of the housing 1 is L2, where R≤L2≤R+8mm applies.

[0040] For example, L2 can be R, R+2 mm, R+4 mm, R+6 mm or R+8 mm.

[0041] The inventors of the present utility model have discovered through experimental investigations that if the distance L2 between the head end K2 of the snail throat surface 211 and the axis center 01 of the wind turbine 3 in the front-back direction of the housing 1 is within the above-mentioned range, the air outlet path of the air outlet duct 2 can be optimized to improve the noise of the air conditioning during wind discharge and to increase the air supply efficiency.

[0042] In particular, in a projection surface perpendicular to the axial direction of the wind turbine 3, the distance between the head end K2 of the worm throat surface 211 and the axis center 01 of the wind turbine 3 in the top-bottom direction of the housing 1 is H2, where 0 ≤ H2 ≤ R / 3. For example, H2 is 0, R / 5, R / 4 and R / 3.

[0043] It is understandable that, as in Fig. 2 and Fig. As shown in Figure 3, the head end K2 of the spiral groove surface 211 can be located above, or above or below, the axis center 01 of the wind turbine 3. The head end K2 of the spiral groove surface 211 takes the horizontal plane passing through the axis center 01 of the wind turbine 3 as its reference plane, and the maximum distance by which it can move up and down is R / 3, i.e., the head end K2 of the spiral groove surface 211 is positioned next to the reference plane.

[0044] The inventors of the present utility model have discovered through experimental investigations that the structure of the air outlet duct 2 can be designed more effectively if the distance H2 between the head end K2 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 lies within the aforementioned range. This helps to reduce the resistance of the airflow as it flows through the spiral groove surface 211 and reduces the noise of the airflow as it flows through the spiral groove surface 211.

[0045] As in Fig. As shown in Figure 2, in the example of the present utility model, the coordinate point (L2, H2) of the head end K2 of the snail throat surface 211 is (-R-8mm to -R, -R / 3 to R / 3). As shown in Fig. As shown in Figure 4, when solving the air outlet duct (before optimization) in the relevant technique, the coordinate point (L2', H2') of the head end K2 of the snail throat surface is 211 (-R to -R / 2, -4R / 5 to -R / 2).

[0046] The inventors of the present utility model have found through experimental investigations that if the coordinate point (L2, H2) of the head end K2 of the spiral groove surface 211 lies within the range of (-R-8mm to -R, -R / 3 to R / 3), the arrangement path of the air outlet channel 2 can be optimized to reduce the resistance of the airflow as it flows through the spiral groove surface 211, and to reduce the noise as the airflow flows through the spiral groove surface 211, and thereby significantly improving the air supply efficiency.

[0047] Optional, as in Fig. As shown in Figure 3, 45 mm ≤ R ≤ 60 mm applies. For example, R can be 45 mm, 50 mm, 55 mm, or 60 mm. The inventors of the present utility model have found through experimental investigations that the size of the air conditioner can be reduced if the impeller assumes the aforementioned radius size, while simultaneously ensuring that the air conditioner has good air supply efficiency and effect. This results in a thinner and lighter overall machine structure and lower energy consumption.

[0048] In some embodiments, such as in Fig. As shown in Figure 3, it is intended that in the direction of extension from the rear end K1 of the snail throat surface 211 to the head end of the snail throat surface 211 (as in the direction from bottom to top in Fig. (as shown in Figure 3) the gap W between the snail groove surface 211 and the wind turbine 3 gradually decreases, where 1 mm ≤ W ≤ 8 mm. This increases the pressure head performance of the fan and improves the vibration and noise reduction effect of the air conditioner.

[0049] For example, W can be 1 mm, 3 mm, 5 mm, 7 mm or 8 mm.

[0050] In some embodiments, such as in the Fig. 2 and Fig. As shown in Figure 3, 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.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.

[0051] 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.

[0052] Specifically, the air outlet duct 2 comprises, as shown in Fig. 2 and Fig. Figure 3 shows a second air duct wall 22, the second air duct wall 22 comprising a helical tongue surface 221 and a second air guide surface 222, the helical tongue surface 221 being spaced radially from the wind turbine 3, one end of the second air guide surface 222 being connected to the helical tongue surface 221 and the other end of the second air guide surface 222 being connected to the lower edge of the air outlet 12, the extension surface 213 and the second air guide surface 222 being arranged relative to each other along the top-bottom direction of the housing 1.

[0053] When the air outlet duct 2 directs the air, the extension surface 213 and the second air guide surface 222, which are oriented opposite each other in a top-bottom direction, can direct the airflow from back to front after heat exchange from the air outlet 12. Compared to the solution "the air outlet duct directs the wind upwards," the problem of airflow obstruction by wind discharge at the ceiling can be avoided. This reduces the energy consumption of the air conditioner and helps to distribute the airflow more evenly over a larger area in the room, while maintaining good air supply.

[0054] Optionally, as in Fig. 2 and Fig. Figure 3 shows the front end of the extension surface 213 being closer to the front of the housing 1 than the front end of the second air guide surface 222.

[0055] In other words, the front end of the extension surface 213 is located in front of the front end of the second air guide surface 222, thereby increasing the wind guide path, which allows the air discharge distance of the air conditioner to be extended, helping the discharged cold or warm air to flow evenly and slowly over a larger area in order to achieve rapid cooling (heating).

[0056] In the example of the present application, to adapt to the structure of the air outlet end of the air outlet duct 2, the upper edge of the air outlet 12 is positioned in front of the lower edge of the air outlet 12. When the air conditioning system is in operation, the airflow, after heat exchange, flows along the air outlet duct 2 and is discharged through the air outlet 12, thereby reducing the resistance of the airflow and improving the air supply effect.

[0057] 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 to exchange heat for the airflow entering the housing 1.

[0058] In the air conditioning system of the embodiments of the present utility model, the arrangement of the air outlet 12 on the front wall surface of the housing 1 and the connection of the air outlet duct 2 with the air outlet 12, compared to the solution "the air outlet is directed towards the top wall", avoids the problem of the airflow being blocked by wind exhaust at the ceiling, 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, by setting the distance L1 between the rear end K1 of the spiral groove surface 211 and the axis center 01 of the wind turbine 3 in the front-to-back direction of the housing 1 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 airflow passes through the spiral groove surface 211. Therefore, the air conditioning system of the embodiments of the present utility model can increase the air supply area and improve the air supply effect and efficiency.
