Description

Technical Field

[0001] This application relates to the field of air conditioning technology, for example to a housing for an air conditioner and an air conditioner. Background Technology

[0002] Currently, during the cooling season, condensation often occurs at the air outlets of household air conditioners. Water droplets accumulate at the edges of the outlets, gradually forming larger droplets that eventually fall due to gravity. Condensation can also run down the wall behind the indoor unit's frame, damaging fixtures, furniture, and other items below the unit, causing losses and affecting the user experience. While insulation material is typically used to cover the inner surface of the air outlet edges, condensation can remain inside this material after prolonged use, reducing its insulation effectiveness and causing condensation to reappear on the cold surface. Furthermore, mold growth on the insulation can lead to hygiene problems and unpleasant odors.

[0003] The related technology discloses an anti-condensation technology that, when designing the air duct of the indoor unit of an air conditioner, minimizes the turbulence of the cold air outlet and prevents the hot air from blowing onto the surface of the air outlet.

[0004] In the process of implementing the embodiments of this disclosure, at least the following problems were found in the related art:

[0005] The anti-condensation technology in related technologies has high requirements for the design of the air duct and the air outlet speed. The design of the air outlet duct will limit the range of air delivery angle. By adjusting the design of the air outlet airflow, a high air outlet speed needs to be maintained so that the air outlet forms a jet to reduce the impact of the air outlet turbulence on the edge surface of the air outlet. All of these will affect the air conditioner's performance and the user's experience.

[0006] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this application, and therefore may include information that does not constitute prior art known to those skilled in the art.

[0007] To provide a basic understanding of some aspects of the disclosed embodiments, a brief summary is given below. This summary is not intended as a general commentary, nor is it intended to identify key / important components or describe the scope of protection of these embodiments, but rather as a prelude to the detailed description that follows.

[0008] This disclosure provides a housing and an air conditioner for use in air conditioning, so as to prevent condensation while ensuring the air conditioning's air output effect.

[0009] This disclosure provides a housing for an air conditioner, the housing defining an air outlet duct, the duct including an impeller cavity and an air outlet duct connected sequentially along the airflow direction; wherein, a first vacuum insulation layer is provided on the side of the housing away from the air outlet duct, and the first vacuum insulation layer corresponds to the air outlet duct.

[0010] In some alternative embodiments, the housing includes: a cover; a frame located inside the cover, the frame having an impeller cavity and a first air outlet duct inside; wherein, the cover includes an air outlet cover connected to the lower end of the rear side wall of the frame, the air outlet cover and the front side wall of the frame enclose a second air outlet duct, the inlet of the second air outlet duct is connected to the outlet of the first air outlet duct, and a first vacuum insulation layer is disposed on the side of the air outlet cover away from the second air outlet duct.

[0011] In some alternative embodiments, the housing further includes: a connecting housing connected to the lower end of the air outlet housing and extending toward a side away from the second air outlet duct; wherein the connection between the connecting housing and the air outlet housing forms a bent structure, the first vacuum insulation layer is located within the bent structure, and / or the first vacuum insulation layer is located on the side of the connecting housing away from the bent structure.

[0012] In some alternative embodiments, the length of the first vacuum insulation layer matches that of the bent structure, or there are multiple first vacuum insulation layers, and the length directions of the multiple first vacuum insulation layer bent structures are arranged sequentially at intervals.

[0013] In some alternative embodiments, when the first vacuum insulation layer is located within the bent structure, the cross-sectional area of ​​the first vacuum insulation layer matches the cross-sectional area of ​​the bent structure; or, the first vacuum insulation layer is located on the side of the air outlet shroud away from the second air outlet duct.

[0014] In some alternative embodiments, the housing further includes: a front housing connected to the upper end of the front sidewall of the air outlet frame, the front sidewall of the air duct including the front housing; the housing further includes: a front panel disposed on the outside of the front housing; wherein the front panel is provided with a second vacuum insulation layer.

[0015] In some alternative embodiments, the second vacuum insulation layer is disposed on the side of the front panel away from the front cover; and / or, the ratio of the thickness of the second vacuum insulation layer to the thickness of the front panel is 1 to 20; and / or, the ratio of the area of ​​the second vacuum insulation layer to the area of ​​the front panel is 0.3 to 1; and / or, at least a portion of the second vacuum insulation layer is disposed on the lower part of the front panel.

[0016] In some alternative embodiments, the side of the frame away from the air duct is provided with an insulation layer, or the frame is provided with a third vacuum insulation layer.

[0017] In some alternative embodiments, the air outlet duct is provided with an air outlet, and the housing for the air conditioner further includes: an air guide plate disposed at the air outlet; wherein the air guide plate is provided with a fourth vacuum insulation layer; and / or, the outer wall surface of the air outlet duct is provided with a nano-coating.

[0018] This disclosure also provides an air conditioner, which includes a housing for an air conditioner as described in any of the above embodiments.

[0019] The housing and air conditioner for an air conditioner provided in this disclosure can achieve the following technical effects:

[0020] The housing for an air conditioner in this embodiment includes a first vacuum insulation layer on the outside of the air outlet duct. Since the airflow temperature inside the air outlet duct is low, and the sidewall of the duct is in contact with the outside airflow, condensation easily forms on the outer surface of the sidewall. By providing the first vacuum insulation layer on the side of the housing away from the air outlet duct, the heat exchange between the sidewall of the air outlet duct and the outside airflow is reduced, ensuring that the surface temperature of the outer surface of the sidewall of the air outlet duct does not fall below the dew point temperature of the outside hot air, thus preventing condensation. Compared to using insulation material, this embodiment reduces the need for insulation material near the air outlet by providing the first vacuum insulation layer, optimizing production costs and processes, and improving the production efficiency of the air conditioning production line. It also prevents the insulation material near the air outlet from aging and decaying due to water absorption after prolonged use, thus avoiding reduced insulation performance and hygiene problems. Using a first vacuum insulation layer to prevent condensation ensures that the air conditioner's cooling capacity is used for sensible heat absorption as much as possible, reducing latent heat absorption, increasing the room's cooling speed, and also having a positive impact on energy efficiency testing.

[0021] Furthermore, by implementing a first vacuum insulation layer to prevent condensation, there is no need to alter the air duct or adjust the airflow speed. This ensures consistent airflow range and speed, thereby improving the user experience. Moreover, the first vacuum insulation layer eliminates the need for additional thermal insulation materials, preventing issues such as mold growth and odors.

[0040] It should be noted that, unless otherwise specified, the embodiments and features described in the present disclosure can be combined with each other.

[0041] For ease of description, the front-back and top-bottom directions of this application are as follows: Figure 1 , Figure 7 and Figure 8 As shown.

[0042] Combination Figures 1 to 8As shown, this embodiment of the present disclosure provides a housing for an air conditioner, the housing defining an air duct 40, the side wall of the air duct 40 being provided with a vacuum insulation layer, the vacuum insulation layer being able to prevent the temperature of the side wall of the air duct 40 from lowering the dew point temperature of the outside air, thereby preventing condensation on the side wall of the air duct 40.

[0043] Optionally, the air duct 40 is provided with an air inlet 43 and an air outlet 44. The air duct 40 includes an impeller cavity 42 and an air outlet duct 41 connected sequentially along the airflow direction. An impeller 60 is provided in the impeller cavity 42, and the air outlet 44 is located at the outlet end of the air outlet duct 41. A first vacuum insulation layer 50 is provided on the side of the housing facing away from the air duct 40, and the first vacuum insulation layer 50 corresponds to the air outlet duct 41. It can be understood that the first vacuum insulation layer 50 is located close to the outlet 44.

[0044] In this embodiment, a first vacuum insulation layer 50 is provided on the outside of the air outlet duct 41. This reduces heat exchange between the side wall of the air outlet duct 41 and the outside environment, increases the temperature of the side wall of the air outlet duct 41, and prevents the temperature of the side wall of the air outlet duct 41 from being lower than the dew point temperature of the airflow in the outside environment. This prevents condensation on the outer wall of the air outlet duct 41, thus preventing the condensed water droplets from the air outlet 44 from accumulating to a certain size and dripping down, damaging the user's home decoration, furniture, and other items.

[0045] Optionally, the heat exchanger 61 is located within the air duct 40.

[0046] Optionally, the air inlet 43 is located at the upper end of the housing, and the air outlet 44 is located at the lower end of the housing.

[0047] Optionally, such as Figure 1 As shown, the housing includes a cover 10 and a frame 20. The frame 20 is located inside the cover 10. The frame 20 has an impeller cavity 42 and a first air outlet duct inside. The cover 10 includes an air outlet cover 12, which is connected to the lower end of the rear side wall 21 of the frame. The air outlet cover 12 and the front side wall 22 of the frame enclose a second air outlet duct. The inlet of the second air outlet duct is connected to the outlet of the first air outlet duct. A first vacuum insulation layer 50 is provided on the side of the air outlet cover 12 away from the second air outlet duct.

[0048] In this embodiment, the air outlet cover 12 is connected to the lower end of the frame 20, so that the second air outlet duct is closer to the air outlet 44, that is, the air outlet cover 12 is closer to the air outlet 44. A first vacuum insulation layer 50 is provided on the side of the air outlet cover 12 away from the second air outlet duct, which can effectively prevent condensation from occurring at the air outlet 44.

[0049] Optionally, the housing 10 further includes a connecting housing 13, which is connected to the lower end of the air outlet housing 12 and extends toward the side away from the second air outlet duct; wherein, as Figure 2 As shown, a bent structure 14 is formed at the connection between the connecting cover 13 and the air outlet cover 12, such as... Figures 3 to 5 As shown, the first vacuum insulation layer 50 is located inside the bent structure 14, and / or the first vacuum insulation layer 50 is located on the side of the connecting cover 13 away from the bent structure 14.

[0050] In this embodiment, the first vacuum insulation layer 50 is disposed on the outside of the air outlet duct 41, effectively blocking heat exchange between the sidewall of the air outlet duct 41 and the external environment. Because the interior of the first vacuum insulation layer 50 is close to a vacuum, heat transfer methods such as heat conduction and convection are greatly restricted, making the temperature of the sidewall of the air outlet duct 41 less susceptible to the influence of the low-temperature external environment, thus preventing the sidewall temperature from dropping below the dew point temperature. The connecting cover 13 is connected to the lower end of the air outlet cover 12, ensuring the strength and stability of the air outlet cover 12. The connecting cover 13 is located lower and closer to the air outlet 44, and is easily exposed to external airflow. Therefore, the first vacuum insulation layer 50 is disposed within the bending structure 14 between the connecting cover 13 and the air outlet cover 12. This reduces heat exchange between the air outlet duct 41 and the outside environment, thereby preventing condensation on the connecting cover 13 and the air outlet cover 12. The first vacuum insulation layer 50 can also be disposed on the side of the connecting cover 13 away from the bending structure 14. This reduces the contact between the external airflow and the connecting cover 13 from the outside, preventing the temperature of the connecting cover 13 from dropping below the dew point of the outside air, thereby preventing condensation on the connecting cover 13. Furthermore, this also isolates the heat exchange between the inside of the bending structure 14 and the outside, preventing condensation on the outlet cover 12.

[0051] In some alternative embodiments, such as Figures 3 to 5 as well as Figure 7 As shown, a first vacuum insulation layer 50 is provided inside the bent structure 14. The cross-sectional area of ​​the first vacuum insulation layer 50 matches the cross-sectional area of ​​the bent structure 14. That is, the structure, shape and size of the first vacuum insulation layer 50 are the same as or similar to those of the bent structure 14. In this way, the first vacuum insulation layer 50 can fill the bent structure 14, improving the vacuum layer state. This allows for better insulation between the connecting cover 13 and the air outlet cover 12, reducing or preventing condensation on the air outlet cover 12 and the bent structure 14. This also prevents condensation from dripping onto the connecting cover 13 and then onto the outside of the air conditioner, thus preventing water leakage from the indoor unit.

[0052] For example, such as Figures 3 to 5 as well as Figure 7 As shown, the cross-section of the bent structure 14 is triangular, and the first vacuum insulation layer 50 is also called a triangular structure.

[0053] In other alternative embodiments, such as Figure 8As shown, a first vacuum insulation layer 50 is provided inside the bent structure 14 and on the wall surface of the connecting cover 13 away from the bent structure 14. The first vacuum insulation layer inside the bent structure 14 is defined as the inner vacuum insulation layer, and the first vacuum insulation layer on the wall surface of the connecting cover 13 away from the bent structure 14 is defined as the outer vacuum insulation layer. The inner vacuum insulation layer is provided on the air outlet cover 12. That is, the inner vacuum insulation layer is provided on the side of the air outlet cover 12 away from the second air outlet duct. In this way, the connecting cover 13 and the air outlet cover 12 are provided with two vacuum insulation layers for heat insulation, forming multiple protections and improving the anti-condensation effect.

[0054] Optionally, the length of the first vacuum insulation layer 50 is matched with the length of the bent structure 14. That is, the length of the first vacuum insulation layer 50 is the same as or similar to the length of the bent structure 14, which can ensure the anti-condensation effect in the length direction of the air outlet duct 41.

[0055] Optionally, there may be multiple first vacuum insulation layers 50, and the multiple first vacuum insulation layers 50 bending structures 14 are arranged at intervals along their length direction.

[0056] In this embodiment, the first vacuum insulation layer 50 can also be segmented, which can avoid components in the bending length direction and improve the anti-condensation effect without affecting the function of the cover 10.

[0057] Optionally, the exhaust shroud 12 can be detachably connected to the lower end of the rear side wall 21 of the frame. This facilitates the connection and disassembly of the exhaust shroud 12 and the frame 20, and also facilitates the installation of the first vacuum insulation layer 50.

[0058] Optionally, the air outlet cover 12 and the lower end of the rear side wall 21 of the frame can be detachably connected by screws and / or clips.

[0059] Optionally, the lower end of the rear sidewall 21 of the frame is provided with a support rib, which is supported between the air outlet cover 12 and the connecting cover 13, and the support rib is located at the opening of the bent structure 14. In this way, the support rib, the air outlet cover 12 and the connecting cover 13 enclose and form an accommodating space, and the first vacuum insulation layer 50 is disposed in the accommodating space, wherein the accommodating space includes the bent structure 14.

[0060] In this embodiment, the supporting ribs further improve the connection strength between the connecting cover 13 and the air outlet cover 12, and also improve the strength of the bending structure 14. In this way, when the first vacuum insulation layer 50 is placed inside the bending structure 14, the stability of the first vacuum insulation layer 50 can be guaranteed, and damage to the first vacuum insulation layer 50 can be avoided.

[0061] Optionally, the housing for the air conditioner may further include a first heat insulation housing, which itself encloses to form a first vacuum insulation layer 50, or the first heat insulation housing is connected to the cover 10 and encloses the first vacuum insulation layer 50.

[0062] Optionally, if a first vacuum insulation layer 50 is provided inside the bent structure 14, the first insulation shell itself encloses and forms the first vacuum insulation layer 50.

[0063] Optionally, when the air outlet cover 12 is provided with a first vacuum insulation layer 50, the first insulation shell and the wall surface of the air outlet cover 12 away from the second air outlet duct are enclosed to form the first vacuum insulation layer 50.

[0064] Optionally, if the first vacuum insulation layer 50 is provided on the side of the connecting cover 13 away from the bending structure 14, the first insulation shell and the wall surface of the connecting cover 13 away from the bending structure 14 enclose the first vacuum insulation layer 50.

[0065] Optionally, such as Figures 6 to 8 As shown, the housing 10 also includes a front housing 11, which is connected to the upper end of the front sidewall 22 of the air outlet frame. The front sidewall of the air duct 40 includes the front housing 11. The housing also includes a front panel 30, which is located outside the front housing 11. The front panel 30 is provided with a second vacuum insulation layer 51.

[0066] In this embodiment, the front panel 30 is close to the front cover 11, which is the front sidewall of the air duct 40. Therefore, due to convective heat transfer of cold air and radiative heat transfer of the cold surface of the evaporator, the inner surface temperature of the front panel 30 decreases. The outer surface of the front panel 30 also experiences a decrease in temperature due to heat conduction from the inner surface, resulting in a cold surface where condensation occurs. When hot air encounters the cold surface, and the temperature of the cold surface is lower than the dew point temperature of the hot air, condensation occurs. Therefore, a second vacuum insulation layer 51 is provided on the front panel 30. This vacuum state of the second vacuum insulation layer 51 restricts heat transfer methods such as heat conduction and convection, thereby ensuring that the temperature of the front panel 30 is always higher than the dew point temperature of the ambient air, thus preventing condensation on the front panel 30.

[0067] Optionally, the front cover 11 includes a hollow structure.

[0068] Optionally, the front panel 30 is detachably connected to the front cover 11. This facilitates the removal and maintenance of the front panel 30, as well as the inspection of the air conditioner's interior.

[0069] Optionally, the front panel 30 and the front cover 11 are connected by a snap-fit. Specifically, the front panel 30 has a snap-fit ​​part on the side facing the front cover 11, and the front cover 11 has a snap-fit ​​mating part. The snap-fit ​​part and the snap-fit ​​mating part are detachably connected, so that there is no need to set a connection position on the front wall of the front panel 30, ensuring the structural integrity and appearance uniformity of the front panel 30.

[0070] Optionally, at least a portion of the second vacuum insulation layer 51 is disposed on the lower part of the front panel 30.

[0071] In this embodiment, since the air outlet 44 is located at the bottom of the cover 10, the lower end of the front panel 30 is close to the air outlet 44, and the lower end of the front panel 30 is prone to condensation. Therefore, the second vacuum insulation layer 51 is disposed at the lower part of the front panel 30, which can effectively prevent condensation on the front panel 30.

[0072] Optionally, the lower end of the second vacuum insulation layer 51 is flush with the lower end of the front panel 30, or the lower end of the second vacuum insulation layer 51 is located close to the lower end of the front panel 30. In this way, the second vacuum insulation layer 51 can better prevent condensation on the front panel 30.

[0073] Optionally, the second vacuum insulation layer 51 is disposed on the side of the front panel 30 away from the front cover 11. In this way, the second vacuum insulation layer 51 will not affect the connection between the front panel 30 and the front cover 11, nor will it occupy the space in the air duct 40, ensuring the normal operation of the air conditioner, and is easy to process and has a simple structure.

[0074] Optionally, the ratio of the thickness of the second vacuum insulation layer 51 to the thickness of the front panel 30 is 1 to 20.

[0075] In this embodiment of the present disclosure, when the thickness of the second heat insulation layer is greater than or equal to the thickness of the front panel 30, and the ratio of the thickness of the second heat insulation layer to the thickness of the front panel 30 is within 1 to 20, the thickness of the vacuum layer of the second vacuum heat insulation layer 51 can be guaranteed, thereby ensuring the heat insulation effect and improving the anti-condensation effect.

[0076] Optionally, the ratio of the thickness of the second vacuum insulation layer 51 to the thickness of the front panel 30 is 5 to 10, or 5 to 15, or 5 to 20, etc.

[0077] For example, the ratio of the thickness of the second vacuum insulation layer 51 to the thickness of the front panel 30 can be 1, 2, 3, 5, 6.5, 7, 7.5, 10, 11.5, 12, 14, 15, 16, 18, 19, or 20, etc.

[0078] Optionally, the ratio of the area of ​​the second vacuum insulation layer 51 to the area of ​​the front panel 30 is 0.3 to 1.

[0079] In this embodiment, the area of ​​the second vacuum insulation layer 51 can be the same as the area of ​​the front panel 30. This more comprehensively prevents condensation on the front panel 30, minimizes heat exchange between the front panel 30 and the outside environment, and significantly reduces the risk of condensation on the surface of the front panel 30. This is especially suitable for high-humidity environments or scenarios with strict anti-condensation requirements. The area of ​​the second vacuum insulation layer 51 can also be smaller than the area of ​​the front panel 30, which can reduce the weight of the front panel 30 and lower costs. When the ratio of the area of ​​the second vacuum insulation layer 51 to the area of ​​the front panel 30 is 0.3, the anti-condensation effect in critical areas (such as near the air outlet 44 or areas easily accessible to users) can be ensured while reducing the number of vacuum insulation layers and lowering production costs.

[0080] Optionally, the ratio of the area of ​​the second vacuum insulation layer 51 to the area of ​​the front panel 30 is 0.3 to 0.8, or the ratio of the area of ​​the second vacuum insulation layer 51 to the area of ​​the front panel 30 is 0.5 to 0.8, or the ratio of the area of ​​the second vacuum insulation layer 51 to the area of ​​the front panel 30 is 0.5 to 0.7.

[0081] For example, the ratio of the area of ​​the second vacuum insulation layer 51 to the area of ​​the front panel 30 is 0.3, 0.4, 0.5, 0.6, 0.7, 0.8, 0.9, or 1, etc.

[0082] Optionally, when the humidity of the air conditioner installation environment is greater than or equal to the first humidity threshold, the ratio of the area of ​​the second vacuum insulation layer 51 to the area of ​​the front panel 30 is greater than or equal to 0.7, which can increase the insulation area and ensure all-round anti-condensation.

[0083] Optionally, when the humidity of the air conditioner installation environment is less than the first humidity threshold and greater than or equal to the second humidity threshold, the ratio of the area of ​​the second vacuum insulation layer 51 to the area of ​​the front panel 30 is greater than or equal to 0.5 and less than or equal to 0.7, which can balance cost and anti-condensation cost.

[0084] Optionally, when the humidity of the air conditioner installation environment is less than the second humidity threshold, the ratio of the area of ​​the second vacuum insulation layer 51 to the area of ​​the front panel 30 is less than 0.5, and the second vacuum insulation layer 51 is set close to the air outlet 44, focusing on insulating the part that is prone to condensation near the air outlet 44 to improve the anti-condensation effect.

[0085] Optionally, the housing for the air conditioner also includes a second heat insulation housing, which together with the front panel 30 forms a second vacuum insulation layer 51.

[0086] Optionally, the frame 20 is provided with an insulation layer on the side facing away from the air duct 40.

[0087] In this embodiment, the frame 20 is the main structure of the air duct 40 and has extensive contact with the cold airflow of the air duct 40. Therefore, the frame 20 has the lowest temperature. To prevent condensation from forming on the frame 20, an insulation layer is provided on the side of the frame 20 facing away from the air duct 40. This reduces heat conduction or convection and prevents the frame 20 from contacting the outside air and generating airflow. The insulation layer can directly cover the outer surface of the frame 20 without affecting the integrity of the original structure, thus reducing costs.

[0088] Alternatively, the insulation layer can be EPP foam, rubber and plastic cotton, etc.

[0089] Optionally, the frame 20 is provided with a third vacuum insulation layer.

[0090] In this embodiment of the disclosure, the frame 20 may also be provided with a third vacuum insulation layer. By providing a vacuum layer on the frame 20, heat conduction can be reduced, achieving a heat insulation effect and preventing condensation on the frame 20.

[0091] In practical applications, anti-condensation structures can be set according to the strength, structure or external environment of the frame 20. When the frame 20 is connected to the fan motor, fan or shell, the frame 20 needs to bear the core load of the whole machine. The frame 20 has high requirements for structural strength. The frame 20 can be equipped with a heat insulation layer to prevent condensation.

[0092] Optionally, the third vacuum insulation layer is formed by the third insulation shell and the frame 20.

[0093] Optionally, when the air conditioner needs to be installed in a high-humidity environment, a third vacuum insulation layer can be installed on the frame 20. Since the risk of condensation is extremely high in high-humidity environments, installing a third vacuum insulation layer on the frame 20 can greatly improve the insulation performance and thus improve the anti-condensation effect.

[0094] Optionally, the air outlet duct 41 is provided with an air outlet 44, and the housing for the air conditioner also includes an air guide plate 62, which is located at the air outlet 44; wherein, the air guide plate 62 is provided with a fourth vacuum insulation layer.

[0095] In this embodiment, the air guide plate 62 is located at the air outlet 44. Therefore, the air guide plate 62 is also located at the junction of cold airflow and hot airflow, and condensation is easily generated on the air guide plate 62. A fourth vacuum insulation layer is provided on the air guide plate 62 to prevent condensation on the air guide plate 62.

[0096] Optionally, the fourth vacuum insulation layer is formed by the fourth insulation material and the air guide plate 62.

[0097] Optionally, a fourth vacuum insulation layer is disposed on the side of the air guide plate 62 away from the air outlet 44.

[0098] Optionally, the outer wall of the air outlet duct 41 is provided with a nano-coating.

[0099] In this embodiment of the disclosure, by providing a nano-coating on the outer wall of the air outlet duct 41, the condensed water is less likely to adhere and accumulate near the air outlet 44, thus eliminating the problem of condensation caused by water droplets falling.

[0100] Optionally, the outer wall of the air outlet duct 41 can be the outer wall of the frame or the outer wall of the casing.

[0101] This disclosure also provides an air conditioner, which includes a housing for an air conditioner as described in any of the above embodiments.

[0102] The air conditioner provided in this disclosure includes the housing of any of the above embodiments, and therefore has the beneficial effects of the housing of any of the above embodiments, which will not be repeated here.

[0103] Optionally, the air conditioner includes an indoor unit and an outdoor unit, the indoor unit including the housing described above for the air conditioner.

[0104] like Figure 7 and Figure 8 As shown, the indoor unit also includes a heat exchanger 61 and an impeller 60. Both the impeller 60 and the heat exchanger 61 are located in the air duct 40. The heat exchanger 61 and the impeller 60 are arranged sequentially along the direction from the air inlet 43 to the air outlet 44.

[0105] Alternatively, the air conditioner can be a wall-mounted air conditioner, a built-in air conditioner, or other types of air conditioners such as cabinet air conditioners. Any method that can use a vacuum insulation layer to prevent condensation is an optional embodiment of this application.
