Description

Technical Field

[0001] This utility model relates to the field of air conditioning technology, specifically to a housing assembly and an air conditioner having the housing assembly. Background Technology

[0002] Air conditioners with bottom air intake and top air outlet are favored by many users due to their advantages in providing uniform temperature distribution and improving overall environmental comfort. In related technologies, in heated carpet mode, because top-outlet air conditioners are installed high, hot air, being less dense, rises and doesn't easily fall to the ground. To increase the temperature in the area where people are active and direct the hot air towards the ground, a guide vane is needed to direct the airflow downwards. Since there is only one air outlet, to achieve a specific airflow angle, the guide vane angle may need to be adjusted too large, resulting in an insufficient airflow area, significant airflow reduction, and the risk of triggering overload and frequency throttling. Furthermore, the small airflow leads to reduced cooling or heating capacity and poor temperature control. Utility Model Content

[0003] This invention aims to at least partially solve one of the technical problems in related technologies. To this end, embodiments of this invention provide a housing assembly for an air conditioner. This housing assembly has the advantages of increasing the overall airflow of the air conditioner and expanding the range of heat flow sweeping angles.

[0007] The housing assembly of this utility model, by providing a second air outlet located below the first air outlet on the front panel, and rotatably connecting a rotating damper to the mating point, allows the second air outlet to be connected to the air supply channel by rotating the damper. In other words, controlling the rotation of the damper controls whether the airflow passes through the second air outlet. Especially in heating mode, opening the second air outlet increases the angle of the hot airflow sweep, allowing the hot airflow to reach the ground more quickly, thus improving heating comfort in carpet mode and avoiding the risk of overload and frequency throttling caused by excessive adjustment of the air guide plate angle. This improves comfort during use and avoids the risk of frequency throttling. Furthermore, the added second air outlet also increases the outlet area, which helps to increase the overall airflow of the air conditioner. Therefore, while increasing the sweep area, it avoids the risk of frequency throttling and increases the overall airflow of the air conditioner.

[0040] 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.

[0041] The following is for reference. Figures 1-7 The present invention describes a housing assembly 10 and an air conditioner 100 having the housing assembly 10.

[0042] The housing assembly 10 of this utility model embodiment has a mating point 104, an air supply channel 103, an air inlet 101 and a first air outlet 102. The air supply channel 103 connects the air inlet 101 and the first air outlet 102. The first air outlet 102 is located above the air inlet 101, and the mating point 104 is disposed in the air supply channel 103.

[0043] The housing assembly 10 includes a front panel 1 and a rotary damper 2. The front panel 1 has a second air outlet located below the first air outlet 102, and the second air outlet is connected to the air supply channel 103. The rotary damper 2 is rotatably connected to the mating point 104 to control whether the second air outlet is connected to the air supply channel 103.

[0044] The housing assembly 10 of this utility model embodiment features a second air outlet located below the first air outlet 102 on the front panel 1. A rotating damper 2 is rotatably connected to a mating point 104. The rotation of the damper 2 controls whether the second air outlet connects to the air supply channel 103. In other words, by controlling the rotation of the damper 2, the airflow can be controlled to exit through the second air outlet. Especially in heating mode, opening the second air outlet increases the angle of the hot airflow sweep, allowing the hot airflow to reach the ground more quickly, thus improving heating comfort in carpet mode. This avoids the risk of overload and frequency throttling caused by excessive adjustment of the air guide plate 4 angle, improving comfort during use and preventing frequency throttling risks. Furthermore, the added second air outlet increases the outlet area, thereby helping to increase the overall airflow of the air conditioner 100. This increases the sweep area while avoiding frequency throttling risks and improving the overall airflow of the air conditioner 100.

[0045] The housing assembly 10 of this utility model embodiment has the advantages of increasing the overall air volume of the air conditioner 100 and increasing the range of hot air sweep angles.

[0046] like Figures 1 to 3As shown, a volute 3 extending toward the interior of the air supply duct 103 is connected to the front panel 1. A portion of the front panel 1 extends upward above the connection point between the volute 3 and the front panel 1 (it can be understood that the upper surface of the front panel 1 is higher than the connection point between the volute 3 and the front panel 1, that is, between the upper and lower surfaces of the volute 3 and the front panel 1, and the volute 3 is connected to the end of the front panel 1 near the first air outlet 102). A portion of the front panel 1 has a second air outlet, and the volute 3 has a mating point 104. The rotary damper 2 has a front end and a rear end. The rear end of the rotary damper 2 is rotatably connected to the mating point 104 of the volute 3 to open and close the second air outlet. When the second air outlet is open, in the height direction of the air conditioner 100, the height of the front end of the rotary damper 2 is between the first air outlet 102 and the connection point.

[0047] The housing assembly 10 of this utility model has a volute tongue 3 extending towards the interior of the air supply duct 103 connected to the front panel 1. A portion of the front panel 1 extends upward above the connection point between the volute tongue 3 and the front panel 1, and the volute tongue 3 has a mating point 104. Thus, the rotating damper 2 is connected to the volute tongue 3 without affecting the air duct structure, and it has the advantage of simple structure.

[0048] like Figures 1 to 3 As shown, the front panel 1 includes a solid plate segment 11 and a perforated plate segment 12 arranged in the vertical direction. The first air outlet 102 is located above the perforated plate segment 12. The volute tongue 3 is connected at the junction of the solid plate segment 11 and the perforated plate segment 12. The perforated plate segment 12 has multiple air outlets 121, and the multiple air outlets 121 form a second air outlet.

[0049] The housing assembly 10 of this utility model is formed by dividing the front panel 1 into a solid plate segment 11 and a perforated plate segment 12 arranged in the vertical direction, and setting a plurality of air outlet holes 121 on the perforated plate segment 12. The second air outlet is formed by directly setting the overall second air outlet, which helps to prevent dust from entering directly through the second air outlet and improves the overall appearance of the air conditioner 100.

[0050] Furthermore, the multiple air outlets 121 are arranged in a matrix, thereby further enhancing the overall aesthetic appeal of the air conditioner 100. It should be noted that this embodiment is not limited to this; in embodiments of the present invention, for example, Figures 5 to 7 As shown, the cross-section of the air outlet 121 can be square, rectangular, trapezoidal or circular, etc.

[0051] The equivalent diameter D of the air outlet 121 on the front panel 1 is 4mm ≥ D ≥ 2mm. This avoids the problem of excessively large air outlet 121 causing direct airflow, and also avoids the problem of insufficient airflow at the second air outlet due to excessively small air outlet 121, resulting in reduced air volume.

[0052] Optionally, the equivalent diameter D of the air outlet 121 of the front panel 1 can be 2.0mm, 2.2mm, 2.4mm, 2.6mm, 2.8mm, 3.0mm, 3.2mm, 3.4mm, 3.6mm, 3.8mm and 4.0mm.

[0053] like Figures 1 to 4 As shown, the volute 3 includes a bent and smoothly connected air outlet section 31, a bent section 32, and an air guide section 33. The front end of the air guide section 33 is connected to the connection between the solid plate section 11 and the perforated plate section 12. The air guide section 33 extends above the air outlet section 31, and the air guide section 33 and the air outlet section 31 are spaced apart in the height direction of the air conditioner 100. The front end of the air outlet section 31 is cantilevered, and the front end of the air outlet section 31 extends towards the direction close to the first air outlet 102. The rear end of the rotary damper 2 is rotatably connected to the front end of the air outlet section 31. Figure 1 As shown, the lower end of the bent section 32 is connected to the rear end of the air outlet section 31, the upper end of the bent section 32 is connected to the air guide section 33, and there is a gap between the front end of the air guide section 33 and the first air outlet 102.

[0054] The housing assembly 10 of this utility model is divided into a volute 3 into a bent and smoothly connected air outlet section 31, a bent section 32, and a guide section 33. The guide section 33 and the air outlet section 31 are spaced apart in the height direction of the air conditioner 100. The front end of the air outlet section 31 is cantilevered. The rotary damper 2 is rotatably connected to the front end of the air outlet section 31, thereby providing rotation space for the rotation of the rotary damper 2 so as to realize the connection between the second air outlet and the air supply channel 103.

[0055] In addition, the air outlet section 31, the bend section 32 and the air guide section 33 are smoothly connected, which not only achieves air guidance but also has the advantage of low wind resistance.

[0056] like Figures 2 to 4 As shown, when the second air outlet is open, the front end of the rotating damper 2 rests on the air outlet section 31, and when the second air outlet is closed, the height of the front end of the rotating damper 2 is flush with the upper edge of the orifice plate section 12.

[0057] In this embodiment of the utility model, the housing assembly 10 can completely close the second air outlet by having the front end of the rotating damper 2 aligned with the upper edge of the perforated plate section 12 when the second air outlet is closed, thereby achieving centralized air outlet.

[0058] like Figures 1 to 4As shown, the section of the air outlet section 31 near the front end has an air outlet plane. The extension line of the air outlet plane is collinear with the upper edge of the orifice plate section 12 (the lower edge of the air outlet). In the plane where the air outlet plane is located, the distance between the rear end of the air outlet plane and the lower edge of the air outlet is L1. The length L2 from the front end of the rotary damper 2 to the rear end of the rotary damper 2 is 0.9≥L2 / L1≥0.6.

[0059] The housing assembly 10 of this utility model has an air outlet plane near the front end of the air outlet section 31. The extension line of the air outlet plane is collinear with the lower edge of the air outlet. The air outlet plane passes smoothly and completely through the air outlet section 31, thereby increasing the air volume under the temperature control effect of the air conditioner 100.

[0060] Furthermore, by limiting the value between L2 and L1, it is possible to avoid the problem that an excessively large value would cause airflow to flow directly out of the second air outlet and fail to pass through it smoothly; it also avoids the problem that an excessively large value would cause the airflow to have a large impact on the front panel 1, resulting in excessive noise. Therefore, the housing assembly 10 of this utility model embodiment has the advantages of low noise and good airflow smoothness.

[0061] Optionally, L2 / L1 can be 0.6, 0.7, 0.8 or 0.9.

[0062] The width of the first air outlet 102 is L3, and the width of the second air outlet is L4. The condition 0.6≥L4 / L3≥0.3 must be met.

[0063] The housing assembly 10 of this utility model, through the ratio of the second air outlet to the first air outlet 102, can avoid the problem that the value of L4 / L3 is too large, resulting in a small size of the first air outlet 102 and poor airflow smoothness; it also avoids the problem that the value of L4 / L3 is too small, resulting in a small second air outlet and an excessively large adjustment angle of the air guide plate 4 on the first air outlet 102, which may easily trigger the risk of overload and frequency reduction.

[0064] Optionally, L4 / L3 can be 0.3, 0.4, 0.5 or 0.6.

[0065] In some embodiments, the rotation angle range of the rotary damper 2 is 0°-40°. This avoids both the problem of excessively large angles occupying space and the problem of excessively small ranges limiting the opening of the second air outlet.

[0066] like Figures 1 to 4 As shown, in a cross-section orthogonal to the length of the air conditioner 100, the upper surface of the rotary damper 2 is arranged to tilt forward from top to bottom. This creates a downward tilt angle, allowing airflow to flow towards the ground and improving the customer experience when the air conditioner 100 is started.

[0067] On a cross section orthogonal to the length of the air conditioner 100, the front panel 1 is arranged to gradually tilt backward from top to bottom.

[0068] Specifically, such as Figure 1 As shown, the front wall of the front panel 1 extends from top to bottom and is arranged at an angle to the rear. That is, the front wall of the front panel 1 is an inclined surface that slopes from top to bottom and to the rear. The upper end of the front wall of the front panel 1 is located in front of the lower end of the front wall of the front panel 1, and the air outlet faces forward and is located above the front panel 1.

[0069] In this embodiment of the utility model, the airflow from the air outlet of the housing assembly 10 flows downward along the extension direction of the front panel 1. The front wall of the front panel 1 is arranged to be tilted backward. The front wall of the front panel 1 guides the airflow to flow downward along the front wall of the front panel 1. The further downward the airflow flows, the further backward the front wall of the front panel 1 is from the vertical plane, making it easier for the airflow to flow downward and land. It also increases the flow distance of the airflow on the ground, thereby increasing the sweeping area.

[0070] Furthermore, this makes it possible to operate in heating mode (e.g., Figure 3 (As shown in the carpet pattern), the lower side of the air outlet can also allow airflow, resulting in a higher temperature of the airflow entering through the air inlet 101. This achieves internal circulation of hot air, enabling high-temperature sterilization of the heat exchanger and preventing odors from appearing on the housing assembly 10. Optionally, an air inlet grille 5 can be provided at the air inlet 101.

[0071] The housing assembly 10 of this utility model embodiment also includes an air guide plate 4, which is movably disposed at the first air outlet 102 to open or close the first air outlet 102.

[0072] For example, Figures 1 to 3 As shown, the air conditioner 100 of this utility model embodiment can have a skylight mode, a sleep mode, and a carpet mode. In the skylight mode, the air guide plate 4 opens the first air outlet 102, and the rotating damper 2 closes the second air outlet; in the sleep mode, the air guide plate 4 closes the first air outlet 102, and the rotating damper 2 closes the second air outlet; in the carpet mode, the air guide plate 4 opens the first air outlet 102, and the rotating damper 2 opens the second air outlet.

[0073] The distance between the upper surface of the housing assembly 10 and the top wall of the wall 200 is H, where H ≥ 5cm. This allows for sufficient space at the top for easy disassembly and reassembly during after-sales service.

[0074] The air conditioner 100 of this utility model embodiment includes a heating element 30, an evaporator 20, a fan 40, and a housing assembly 10 according to any one of the above. The heating element 30, the evaporator 20, and the fan 40 are all disposed in the air supply channel 103.

[0075] Therefore, the air conditioner 100 of this utility model embodiment has the advantages of increasing the overall air volume of the air conditioner 100 and increasing the range of the hot air sweep angle.

[0076] In a cross-section orthogonal to the length of the air conditioner 100, the evaporator 20 includes a first component 201 and a second component 202 arranged at an angle, with the joint of the first component 201 and the second component 202 protruding toward the air inlet 101. The heating element 30 is disposed within the angled area formed by the first component 201 and the second component 202. Optionally, a drip tray 50 may be provided below the joint.

[0077] The air conditioner 100 of this embodiment improves the uniformity of heating of the evaporative airflow in the first component 201 and the second component 202 by placing the heating element 30 within the angled area formed by the first component 201 and the second component 202. This is beneficial for improving the uniformity of the outlet air temperature of the air conditioner 100.

[0078] In some embodiments, the evaporator 20 is arranged in a two-fold integral structure, which makes the internal structure of the air conditioner 100 relatively simple, the air flow path short and direct, and the air flow space relatively large. This avoids the situation where the internal space is tight and affects the air intake when the structure is complex, reduces the possibility of dust accumulation, reduces the overall wind resistance and the workload of the fan 40, and also reduces the energy consumption ratio of the air conditioner and the user's operating cost. In this way, it can improve the air volume and reduce noise.

[0079] This application is not limited to this. In other embodiments, the evaporator 20 can also be set in two parts. The evaporator 20 can be roughly divided into two parts according to the different extension directions. The two parts are the first component 201 and the second component 202. The first component 201 and the second component 202 can both be generally flat plate structures. The first component 201 can be generally inclined along the direction from front to top to back to bottom, and the second component 202 can be generally inclined along the direction from back to top to front to bottom.
