[0007] According to the housing assembly of the present invention, since the baffle ribs are disposed within the air inlet duct and are connected to at least one of the first and second walls, when outside air is drawn into the air inlet duct through the air inlet, the airflow impacts the inner wall of the air inlet duct. The baffle ribs can turbulently flow the airflow impacting the first and / or second walls to reduce the impact force of the airflow, thereby reducing the noise generated by the airflow impacting the inner wall of the air inlet duct when the air conditioner is intake. Therefore, the housing assembly of the present invention can reduce noise during air intake, which is beneficial to improving the user experience.

In the same horizontal direction, the width of the first duct in the front-rear direction is greater than the width of the second duct in the front-rear direction. The baffles are provided on the first wall.

[0009] In some embodiments, the air inlet duct includes a first duct and a second duct. The first wall is located on the front side of the housing and forms the first duct with the front wall of the heat exchanger. The second wall is located on the rear side of the housing and forms the second duct with the rear wall of the heat exchanger. In the same horizontal direction, the width of the second duct in the front-rear direction is greater than the width of the first duct in the front-rear direction. The baffles are provided on the second wall.

[0010] In some embodiments, the baffle ribs gradually extend downwards in a front-to-back direction, the baffle ribs forming an angle α1 with the front-to-back direction of the housing, and the baffle ribs forming an angle β1 with the first wall surface, wherein 0 < α1 ≤ 60°, 10° ≤ β1 ≤ 80°; or, in a front-to-back direction, the baffle ribs gradually extend upwards in a front-to-back direction, the baffle ribs forming an angle α2 with the front-to-back direction of the housing, and the baffle ribs forming an angle β2 with the first wall surface, wherein 0 < α2 ≤ 60°, 10° ≤ β2 ≤ 100°.

[0030] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0031] The following is a reference appendix. Figures 1 to 4 This invention describes a housing assembly and an air conditioner according to embodiments of the present invention.

[0032] like Figures 1 to 4 As shown, the housing assembly of this utility model embodiment includes: a housing 1 and a baffle 3. The lower wall of the housing 1 is provided with an air inlet 11, and the upper side of the housing 1 is provided with an air outlet 12. The inner wall of the housing 1 includes a first wall surface 13 and a second wall surface 14. The first wall surface 13 and the second wall surface 14 are respectively located on the front and rear sides of the heat exchanger 4. At least one of the first wall surface 13 and the second wall surface 14 forms an air inlet duct 2 with the wall of the heat exchanger 4. The baffle 3 is disposed in the air inlet duct 2 and is connected to at least one of the first wall surface 13 and the second wall surface 14.

[0033] For example, the baffle 3 may be provided only on the first wall surface 13. Or, the baffle 3 may be provided only on the second wall surface 14. Or, for another example, the baffle 3 may be provided on both the first wall surface 13 and the second wall surface 14.

[0034] It should be noted that the up, down, front, back, left, and right directions of the casing 1 are consistent with the up, down, front, back, left, and right directions of the air conditioner after installation.

[0035] According to the housing assembly of the present invention, since the baffle 3 is disposed inside the air inlet duct 2 and is connected to at least one of the first wall surface 13 and the second wall surface 14, when outside air is drawn into the air inlet duct 2 through the air inlet 11, the airflow will impact the inner wall of the air inlet duct 2. The baffle 3 can turbulent the airflow impacting the first wall surface 13 and / or the second wall surface 14 to reduce the impact force of the airflow, thereby reducing the noise generated by the airflow impacting the inner wall of the air inlet duct 2 when the air conditioner is intake. Therefore, the housing assembly of the present invention can reduce the noise during air intake, which is beneficial to improving the user experience.

[0036] Optionally, such as Figure 1 and Figure 2As shown, the air inlet duct 2 includes a first air duct 21 and a second air duct 22. The first wall surface 13 is located on the front side of the shell 1 and forms the first air duct 21 with the front wall surface of the heat exchanger 4. The second wall surface 14 is located on the rear side of the shell 1 and forms the second air duct 22 with the rear wall surface of the heat exchanger 4. In the same horizontal direction, the width of the first air duct 21 in the front-to-back direction is greater than the width of the second air duct 22 in the front-to-back direction. The baffle ribs 3 are provided on the first wall surface 13.

[0037] It is understandable that the baffle 3 is located on the wider side of the first air duct 21 and the second air duct 22. In other words, in the same horizontal plane, the front-to-back dimension of the first air duct 21 is larger than that of the second air duct 22. The width of the air duct formed by the first wall 13 and the heat exchanger 4 is larger, and the baffle 3 is located on the first wall 13, that is, the baffle 3 is located on the inner side of the front panel 15 of the shell 1.

[0038] Because the air inlet duct 2 formed between the front panel 15 and the heat exchanger 4 is relatively large, the airflow drawn into the air inlet duct 2 from the air inlet 11 will impact the front wall of the casing 1, which will cause resonance noise to easily occur at the position of the front panel 15. The baffle rib 3 can change the direction of airflow to reduce the noise caused by the airflow directly impacting the first wall 13, which is conducive to improving the quietness of the air conditioner during use and improving the user experience.

[0039] In another example, the air inlet duct 2 includes a first air duct 21 and a second air duct 22. The first wall surface 13 is located on the front side of the shell 1 and forms the first air duct 21 with the front wall surface of the heat exchanger 4. The second wall surface 14 is located on the rear side of the shell 1 and forms the second air duct 22 with the rear wall surface of the heat exchanger 4. In the same horizontal direction, the width of the second air duct 22 in the front-rear direction is greater than the width of the first air duct 21 in the front-rear direction. The baffle ribs 3 are provided on the second wall surface 14.

[0040] It is understandable that the baffle 3 is located on the wider side of the first air duct 21 and the second air duct 22. In other words, in the same horizontal plane, the front-to-back dimension of the second air duct 22 is larger than that of the first air duct 21. The width of the air duct formed by the second wall 14 and the heat exchanger 4 is larger, and the baffle 3 is located on the second wall 14, that is, the baffle 3 is located on the inner wall of the base 16 of the shell 1.

[0041] Because the air inlet duct 2 formed between the base 16 and the heat exchanger 4 is relatively large, the airflow drawn into the air inlet duct 2 from the air inlet 11 will impact the rear wall of the casing 1, which will cause resonance noise to easily occur at the position of the base 16. The baffle rib 3 can change the direction of airflow to reduce the noise caused by the airflow directly impacting the second wall 14, which is beneficial to improving the quietness of the air conditioner during use and improving the user experience.

[0042] Optionally, such as Figure 3 As shown, the turbulence-disrupting ribs 3 gradually extend downwards in a front-to-back direction. The angle between the turbulence-disrupting ribs 3 and the front-to-back direction of the shell 1 is α1, and the angle between the turbulence-disrupting ribs 3 and the first wall surface 13 is β1, where 0 < α1 ≤ 60°, and 10° ≤ β1 ≤ 80°. For example, α1 can be 5°, 10°, 20°, 30°, 40°, 50°, or 60°. β1 can be 10°, 30°, 50°, 70°, or 80°.

[0043] The inventors of this application discovered through experimental research that when the design parameters of the baffle 3 are within the above-mentioned range, the noise generated by the airflow impacting the first wall 13 can be significantly reduced. Furthermore, the baffle 3 can redirect most of the airflow to the wall of the heat exchanger 4, thereby improving the heat exchange efficiency of the airflow and helping to reduce the energy consumption of the air conditioner.

[0044] Optionally, such as Figure 4 As shown, the turbulence-disrupting ribs 3 gradually extend upwards in a front-to-back direction. The angle between the turbulence-disrupting ribs 3 and the front-to-back direction of the shell 1 is α2, and the angle between the turbulence-disrupting ribs 3 and the first wall surface 13 is β2, where 0 < α2 ≤ 60°, 10° ≤ β2 ≤ 100°. For example, α2 can be 5°, 10°, 20°, 30°, 40°, 50°, or 60°. β2 can be 10°, 30°, 50°, 70°, 80°, 90°, or 100°.

[0045] The inventors of this application discovered through experimental research that when the design parameters of the baffle 3 are within the above-mentioned range, the noise generated by the airflow impacting the first wall 13 can be significantly reduced. Furthermore, the baffle 3 can redirect most of the airflow to the wall of the heat exchanger 4, thereby improving the heat exchange efficiency of the airflow and helping to reduce the energy consumption of the air conditioner.

[0046] In other examples, such as Figure 2 As shown, the rib 3 can also extend horizontally in the front-back direction, and this utility model does not limit this.

[0047] Optionally, such as Figure 3 As shown, the thickness of the deflector 3 is t, where 1mm ≤ t ≤ 10mm. For example, t can be 1mm, 3mm, 5mm, 7mm, or 10mm. The inventors of this application discovered through experimental research that when the thickness of the deflector 3 is too small (less than 1mm), on the one hand, the structural strength of the deflector 3 is weak, making it easily damaged by external forces; on the other hand, the deflector 3 is prone to swaying with the impact of airflow, thus generating resonance noise and resulting in poor noise reduction. When the thickness of the deflector 3 is too large (greater than 10mm), the production cost is high, and the deflection effect is poor.

[0048] Therefore, the parameters of the baffle rib 3 of the housing assembly in the embodiment of this utility model are selected within the above range, which can improve the baffle noise reduction performance of the air conditioner and make the baffle rib 3 have sufficient structural strength and good stability.

[0049] Optionally, such as Figure 3 As shown, the distance from the front end to the rear end of the baffle 3 is c, where 1mm ≤ c ≤ 25mm. For example, c can be 1mm, 5mm, 10mm, 15mm, 20mm, or 25mm. The inventors of this application discovered through experimental research that when c is too small (less than 1mm), the baffle 3 has poor turbulence capability, and the noise reduction effect of the air conditioner is not significant. When c is too long (greater than 25mm), the gap between the baffle 3 and the wall of the heat exchanger 4 is small, making it difficult for airflow to pass through the gap. This obstructs the airflow in the air inlet duct 2, resulting in insufficient and uneven contact between the airflow and the wall of the heat exchanger 4, thus reducing the heat exchange effect of the air conditioner.

[0050] Therefore, the parameters of the baffle rib 3 of the shell assembly in the embodiment of this utility model are selected within the above range, which can ensure the normal baffle noise reduction capability of the baffle rib 3, reduce the resistance during airflow heat exchange, improve the heat exchange effect of the air conditioner, and reduce energy consumption.

[0051] Optionally, there may be multiple baffles 3, which extend along the length of the shell 1 and are spaced apart along the vertical direction of the shell 1, thereby making the baffle effect of the baffles 3 more significant. For example, the number of baffles 3 can be 2, 3, 4, or 5. This utility model does not make a specific limitation on the number of baffles 3.

[0052] Optionally, for two adjacent baffles 3, the dimension of the upper baffle 3 in the front-rear direction of the shell 1 shall not be less than the dimension of the lower baffle 3 in the front-rear direction of the shell 1. This can reduce the obstruction of the airflow by the lower baffle 3, which is beneficial to reducing wind loss and improving the smoothness of airflow heat exchange.

[0053] In one example, the size of the baffle 3 gradually increases in the front-rear direction of the shell 1 from bottom to top. This can improve the baffle effect of the baffle 3 and reduce the obstruction of airflow, which is beneficial to reduce wind loss and improve the smoothness of airflow heat exchange.

[0054] In some embodiments, such as Figure 2 As shown, the height difference between the bottommost baffle 3 and the air inlet 11 is a, and the height difference between the topmost baffle 3 and the air inlet 11 is g, where 35mm≤a≤150mm and 100mm≤g≤200mm.

[0055] For example, 'a' can be 35mm, 50mm, 70mm, 90mm, 110mm, 130mm, or 150mm. 'g' can be 100mm, 120mm, 140mm, 160mm, 180mm, or 200mm. It should be noted that while 'a' and 'g' must meet the above parameter ranges, 'g' must also be greater than 'a', meaning the uppermost baffle 3 must be higher than the lowermost baffle 3.

[0056] The inventors of this application discovered through experimental research that when multiple baffles 3 meet the above-mentioned arrangement parameters, the noise generated by the airflow impacting the first wall 13 can be significantly reduced, and the baffles 3 can redirect most of the airflow to the wall of the heat exchanger 4 to improve the heat exchange efficiency of the airflow, which is beneficial to reducing the energy consumption of the air conditioner.

[0057] Optionally, such as Figure 2 As shown, the height difference between two adjacent baffles 3 is b, where 15mm ≤ b ≤ 100mm. For example, b can be 15mm, 30mm, 50mm, 70mm, 90mm, or 100mm. In the example of this application, there are four baffles 3, and all four baffles 3 are arranged with the above-mentioned height difference b to improve the baffle effect of the baffles 3.

[0058] In some embodiments, such as Figure 2 As shown, in the front-rear direction of the shell 1, the distance between the bottommost baffle 3 and the heat exchanger 4 is L1, and the distance between the bottommost baffle 3 and the water receiving tray 5 is L2, wherein 40mm≤L1≤90mm, and 20mm≤L2≤50mm. This ensures the air intake efficiency of the air intake channel.

[0059] For example, L1 can be 40mm, 50mm, 60mm, 70mm, 80mm, or 90mm, and L2 can be 20mm, 25mm, 30mm, 35mm, 40mm, or 50mm. It should be noted that while L1 and L2 must meet the above parameter ranges, L1 must also be greater than L2, meaning that the bottommost baffle 3 should be closer to the water receiving tray 5.

[0060] Optionally, such as Figure 2 As shown, in the front-rear direction of the shell 1, the distance between the uppermost baffle 3 and the heat exchanger 4 is L3, where 20mm≤L3≤50mm. For example, L3 can be 20mm, 30mm, 40mm, or 50mm. This ensures that the uppermost baffle 3 has a good turbulence effect on the airflow, reduces the impact of the airflow on the first wall 13, and allows for a more reasonable arrangement of the baffle 3.

[0061] like Figure 1 and Figure 2As shown, another embodiment of the air conditioner of the present invention includes a housing assembly, a heat exchanger 4 and a fan wheel 6. The housing assembly is the housing assembly of the present invention. The heat exchanger 4 is disposed inside the housing 1, and one side of the heat exchanger 4 is arranged opposite to the air inlet 11, and the other side of the heat exchanger 4 is arranged opposite to the fan wheel 6.

[0062] According to the embodiment of the present invention, the air conditioner has a deflector 3 disposed within the air inlet duct 2 and connected to at least one of the first wall surface 13 and the second wall surface 14. When outside air is drawn into the air inlet duct 2 through the air inlet 11, the airflow impacts the inner wall of the air inlet duct 2. The deflector 3 can turbulentize the airflow impacting the first wall surface 13 and / or the second wall surface 14 to reduce the impact force of the airflow, thereby reducing the noise generated by the airflow impacting the inner wall of the air inlet duct 2 when the air conditioner is drawing in air. Therefore, the air conditioner of the embodiment of the present invention can reduce the noise during air intake, which is beneficial to improving the user experience.

[0063] like Figure 1 As shown, the air inlet 11 is located on the lower wall of the housing 1, and the air outlet 12 is located on the front panel 15 of the housing 1 and is arranged adjacent to the upper side of the housing 1. That is, the air conditioner adopts the form of bottom air inlet and top air outlet, which can improve the air supply effect of the air conditioner.

[0064] For example, such as Figure 1 As shown, the heat exchanger 4 can be V-shaped, with the tip of the V-shape facing the air inlet 11. Alternatively, the heat exchanger 4 can be a straight plate type, which is arranged at an angle inside the shell 1.

[0065] Specifically, such as Figure 1 As shown, the air conditioner also includes a water collection tray 5, which is located inside the housing 1 and at the lower edge of the heat exchanger 4 to collect condensate dripping from the wall of the heat exchanger 4.
