This application proposes an integrated air conditioner. The integrated air conditioner can be a window air conditioner or a mobile air conditioner, which is not limited here.

In the embodiment of the present application, as shown in FIG. 1 and FIG. 2, the integrated air conditioner includes a housing, the housing is provided with an air inlet, an air outlet, and an air duct connecting the air inlet and the air outlet; A chassis, the chassis is provided at the bottom of the housing, the air duct passes through the inner surface of the chassis, the surface of the chassis is provided with a first heat insulation layer, and the first heat insulation layer is heat insulation Coating or flocking layer; a first heat exchanger 30 and a second heat exchanger 40, the first heat exchanger 30 is installed on the chassis 10, the first heat exchanger 30 is close to the air inlet, The second heat exchanger 40 is adjacent to the air outlet.

In this embodiment, the first heat insulation layer 11 can be provided on the upper surface of the chassis 10, can also be provided on the lower surface of the chassis 10, and can also be provided on the side walls of the chassis 10, which is not limited here. In order to make the internal structure of the integrated air conditioner simpler and more compact, reduce the volume of the integrated air conditioner, and ensure the normal function of the integrated air conditioner, the first heat exchanger 30 will be adjacent to the air inlet, and the second heat exchanger 40 will be adjacent to the air outlet. Therefore, before the air flows through the air outlet, it will always flow through the second heat exchanger 40 for heat exchange. When the integrated air conditioner is running, in the cooling mode, the first heat exchanger 30 is in the condensing mode, the second heat exchanger 40 is in the evaporating mode, and the second heat exchanger 40 is close to the air outlet of the integrated air conditioner. The temperature of a heat exchanger 30 is relatively high, and the water pump pours the water from the water storage tank to the first heat exchanger 30, which can reduce the temperature of the first heat exchanger 30 and improve the condensation efficiency of the first heat exchanger 30. The condensed water will lower the temperature inside the chassis 10. At this time, the temperature of the water storage tank is low, and the integrated air conditioner is an environment that requires air conditioning, that is, the ambient temperature is higher than the temperature of the inner surface of the chassis, so that the inner and outer surfaces of the chassis 10 have temperature However, at this time, the outer surface of the chassis 10 is likely to exchange heat with the surrounding environment, forming condensation, which causes the bottom of the integrated air conditioner to be wet or even dripping.

The integrated air conditioner also includes an air duct component 20. The air duct component 20 includes an air inlet component installed on the chassis 10 and adjacent to the first heat exchanger 30, and an air outlet component adjacent to the second heat exchanger 40. The air inlet component forms an air inlet component. The air outlet and the air inlet air duct, the air outlet parts form an air outlet and an air outlet air duct, and a heat exchange air duct is formed between the air inlet part and the air outlet part, and the heat exchange air duct passes through the inner surface of the chassis 10. The air enters the air inlet duct from the air inlet component, and flows to the outlet air duct after heat exchange through the heat exchange duct, so as to realize the adjustment of the air temperature. In the heating mode of the integrated air conditioner, the first heat exchanger 30 is in the evaporating mode, and the second heat exchanger 40 is in the condensing mode. At this time, the temperature of the first heat exchanger 30 is lower, and the air in the air inlet duct It will first flow through the first heat exchanger 30 to form low-temperature air, and then the low-temperature air will flow through the second heat exchanger 40 to form high-temperature air, and then flow to the air outlet duct. After the air flows through the first heat exchanger 30, it will flow through the chassis 10 first, resulting in a lower temperature inside the chassis. At this time, the ambient temperature outside the chassis 10 is affected by the adjustment function of the integrated air conditioner, and the ambient temperature will be higher than that in the chassis 10. The surface temperature causes a temperature difference between the inner and outer surfaces of the chassis 10. At this time, the outer surface of the chassis 10 easily exchanges heat with the surrounding environment to form condensation, which causes the bottom of the integrated air conditioner to be wet or even dripping.

The first heat insulation layer 11 is provided on the chassis 10 to eliminate this temperature difference, thereby avoiding condensation on the outer surface of the chassis 10. The thermal insulation coating is made of one or more of ultra-fine microporous materials, hollow glass, and ceramic microbeads. It has the advantages of strong focus, simple construction and long service life. The flocking layer is made of fluff or short fibers, which can be easily and stably attached to the chassis 10, and has the functions of heat preservation and moisture proof, no lint removal, and friction resistance. The flocking layer and the heat-insulating coating are used as the first heat-insulating layer 11 of the chassis 10, which can be applied to surfaces of different shapes, and can be applied to flat surfaces or curved surfaces. Moreover, for the small surface on the chassis 10, it is inconvenient to stick with traditional sponges, flannels, etc., while the heat-insulating coating and flocking side are easy to construct. Only the heat-insulating coating or flocking layer needs to be evenly applied. Coated on the surface of the chassis 10. In addition, the thermal insulation coating and flocking layer can avoid the clogging caused by the aging or reduced viscosity of the sponge and flannel used in traditional air conditioners due to long-term use, and can also avoid the clogging caused by the above-mentioned clogging problems. The air conditioner is leaking. As a result, the reliability of the air conditioner can be improved.

The chassis 10 of the present application is provided with a heat-insulating coating or flocking layer on the surface, which can prevent condensation on the inner and outer surfaces of the chassis 10 due to the temperature difference.

The inner surface of the chassis has many functional surfaces for the installation of other components, which is not conducive to the arrangement of the first heat insulation layer, and the flocking layer contacts with the condensed water, which will produce peculiar smell, which will affect the user experience; The flock layer is arranged on the outer surface of the chassis 10, which can prevent the heat-insulating coating or flocking layer from being rubbed against the heat exchanger or other integrated air conditioner components installed on the inner surface of the chassis 10 multiple times, thereby reducing the impact on the heat-insulating coating Or the flocking layer is worn out, which increases the service life of the thermal insulation coating or the flocking layer and improves the user experience.

In practical applications, the first heat insulation layer 11 covers the outer surface of the chassis 10. The thermal insulation coating or flocking layer evenly covers the outer surface of the chassis 10, which can minimize the possibility of condensation at various positions on the chassis 10, thereby improving the effective coverage and action rate of the thermal insulation coating and the flocking layer .

The flocking glue layer can be coated on the chassis 10 more conveniently and has higher adhesion to the fluff.

Specifically, the thickness of the flocking layer of the first heat insulation layer is not less than 0.4 mm and not more than 5 mm. In this embodiment, if the thickness of the flocking layer is less than 0.4mm, the heat insulation effect will be poor and the chassis 10 cannot be effectively prevented from condensation; if the thickness of the flocking layer is greater than 5mm, the processing cost will be higher and the fluff will not be stable. Bonded to the chassis 10; therefore, setting the thickness of the flocking layer to 0.4mm to 5mm can not only ensure the heat insulation effect, but also control the processing cost, and make the flocking layer adhere to the chassis 10 more stably. In practical applications, the flocking layer may also be a non-woven bottom flocking layer. The bottom surface of the flocking layer adopts a non-woven bottom, which is not only environmentally friendly, but also has a higher degree of adhesion to the chassis 10.

The air duct member 20 forms the heat exchange air duct of the air conditioner, and the second heat insulation layer 21 may be provided on the inner wall surface of the air duct member 20 or the outer wall surface of the air duct member 20, which is not limited here. When the air conditioner is running, the temperature of the air duct component 20 is higher or lower than the temperature of the surrounding air, and the air duct component 20 exchanges heat with the surrounding air, which will reduce the independent heat circulation of the overall heat exchange system of the air conditioner, resulting in heat loss and affecting The operating energy efficiency of the air conditioner. In addition, the inner and outer wall surfaces of the air duct component 20 have a temperature difference. At this time, the outer wall surface of the air duct component 20 easily exchanges heat with the surrounding environment to form condensation, which causes the outer surface of the air duct component 20 to be wet or even dripping. The second heat insulation layer 21 is provided on the wall surface of the air duct component 20, which can effectively reduce the heat exchange between the air duct component 20 and the surrounding air, thereby improving the independent heat circulation of the heat exchange system, reducing heat loss, and improving the air conditioner’s performance The operation is energy efficient, and at the same time, it can prevent condensation of the air duct components 20. The second heat insulation layer 21 is provided on the wall of the air duct component 20, which can effectively reduce the heat exchange between the air duct component 20 and the surrounding air, thereby improving the independent heat circulation of the heat exchange system, reducing heat loss, and improving the operation of the air conditioner Energy efficiency, while preventing condensation on the air duct components 20.

The flocking layer is made of fluff or short fibers, which can be easily and stably attached to the air duct component 20, and has the functions of heat preservation and moisture proof, no lint removal, and friction resistance. The flocking layer and the heat-insulating coating are used as the second heat-insulating layer 21 of the air duct component 20, which can be applied to surfaces of different shapes, and can be applied to flat surfaces or curved surfaces. Moreover, for the smaller surface existing on the air duct component 20, it is inconvenient to stick with traditional sponges, flannels, etc., while the heat-insulating coating and flocking side are easy to construct, and only the heat-insulating coating or flocking is needed. The layer is uniformly coated on the surface of the air duct member 20. In addition, the thermal insulation coating and flocking layer can avoid the clogging caused by the aging or reduced viscosity of the sponge and flannel used in traditional air conditioners due to long-term use, and can also avoid the clogging caused by the above-mentioned clogging problems. The air conditioner is leaking. As a result, the reliability of the air conditioner can be improved.
