An air conditioner 100 according to an embodiment of the present invention is described below with reference to the accompanying drawings.

As shown in fig. 1 and 2, the air conditioner 100 may include: the heat exchanger comprises a shell member 1, a heat exchange member 2 and a ventilation member 3, wherein an air outlet 15 is formed on the front side of the shell member 1, an air inlet 16 is formed on the left side and/or the right side of the shell member 1, the heat exchange member 2 is arranged in the shell member 1 and comprises a heat exchanger 21 and an electric auxiliary heater 22, the heat exchanger 21 extends forwards in an inclined manner from top to bottom, the heat exchanger 21 is in a rear convex type so as to form a concave space on the front side, namely, the heat exchanger 21 protrudes backwards from the left side and the right side to the center, so that the front side of the heat exchanger 21 forms a concave space opposite to the rear convex position, for example, the heat exchanger 21 can be a U-shaped heat exchanger 21 or a V-shaped heat exchanger 21, and the electric auxiliary heater 22 is arranged in the shell member 1 and is positioned in the concave space on the front side of the heat exchanger 21.

As shown in fig. 2, 3 and 6, the two sides of the thickness of the heat exchanger 21 are a windward side 211 and a leeward side 212, respectively, the windward side 211 is disposed close to the rear side of the housing member 1 relative to the leeward side 212, the ventilation member 3 is disposed in the housing member 1 and below the heat exchanger 21, the ventilation member 3 includes a centrifugal fan and draws air from the air inlet 16 (e.g., in the direction indicated by arrow a shown in fig. 2) and blows air to the windward side 211 of the heat exchanger 21 (e.g., in the direction indicated by arrow B shown in fig. 3), the air flow passes out from the windward side 211 of the heat exchanger 21 to the leeward side 212 of the heat exchanger 21 (e.g., in the direction indicated by arrow C shown in fig. 3 and 6), and the air flow passing out from the windward side 211 of the heat exchanger 21 to the leeward side 212 of the heat exchanger 21 is blown out through the air outlet 15 (e.g., in the direction indicated by arrow D shown in fig. 3).

In the cabinet air conditioner with positive air outlet in the related art, the built-in heat exchanger is flat, three rows are usually adopted, the windward area of the heat exchanger is small, the wind resistance is large, the noise is high, and the heat exchange efficiency is not high. According to the air conditioner 100 provided by the embodiment of the utility model, the heat exchanger 21 is arranged in an inclined and rear-convex manner, so that the windward area can be effectively increased, the heat exchange efficiency is improved, the number of rows is reduced, for example, two rows can be accommodated in the same space, the material cost of the heat exchanger 21 is saved, the wind resistance of the heat exchanger 21 is reduced, and the operation noise of the air conditioner 100 is reduced. Further, since the heat exchanger 21 is of a rear-convex type, the electric auxiliary heat 22 can be accommodated in the concave space on the front side thereof, and the overall structure compactness is improved. In addition, because the ventilation part 3 comprises a centrifugal fan and is positioned below the heat exchange part 2, for the rear convex type heat exchanger 21, the thickness of the whole air conditioner 100 in the front and rear direction can be effectively reduced, and the air volume of the whole air conditioner can be improved. Furthermore, by providing the centrifugal fan, the air inlets 16 can be located on the left and right sides of the housing member 1, rather than on the rear side of the housing, so that the rear side of the housing member 1 can be located against the wall, which is convenient for saving indoor space. In addition, since the heat exchanger 21 is disposed to extend obliquely forward from top to bottom, the space for the ventilation member 3 to supply air to the windward side 211 of the heat exchanger 21 can be increased while increasing the heat exchange area, so that the wind resistance and noise can be reduced more effectively.

It should be noted that the inclination angle of the heat exchanger 21 is not limited, for example, in some embodiments of the present invention, as shown in fig. 3, the inclination angle of the heat exchanger 21 extending obliquely forward from top to bottom is 5 ° to 25 °, that is, the angle a between the rear surface of the heat exchanger 21 and the vertical plane may be 5 ° to 25 °, for example, 5 °, 10 °, 15 °, 20 °, 25 °, and so on. Therefore, the space for the ventilation part 3 to supply air to the windward side 211 of the heat exchanger 21 can be increased while the heat exchange area is increased, so that the effects of wind resistance and noise can be effectively reduced.

Alternatively, the heat exchanger 21 extends obliquely forward from upper to lower at an inclination angle of 10 ° -20 °, i.e., an angle a between the rear surface of the heat exchanger 21 and the vertical plane, may be 10 ° -20 °, for example, may be 10 °, 12 °, 14 °, 16 °, 18 °, 20 °, and so on. Therefore, the space for the ventilation part 3 to supply air to the windward side 211 of the heat exchanger 21 can be increased while the heat exchange area is increased, so that the effects of wind resistance and noise can be effectively reduced.

In some embodiments of the present invention, as shown in fig. 2, the heat exchange member 2 further comprises a mounting bracket 23, the mounting bracket 23 is disposed in the housing member 1 and mounted to the housing member 1, and the left and right sides of the heat exchanger 21 are respectively mounted to the mounting brackets 23. Thus, by providing the mounting bracket 23, the structure of the case member 1, the air duct seal, and the like can be simplified as compared with the case member 1 in which the heat exchanger 21 is directly mounted, and the mounting difficulty of the heat exchanger 21 can be reduced, thereby improving the mounting efficiency of the heat exchanger 21. For example, in conjunction with fig. 3 and 6, the air inlet chamber 17 on the windward side 211 of the heat exchanger 21 can be defined by the mounting bracket 23 and the heat exchanger 21, or by the mounting bracket 23, the heat exchanger 21 and the housing member 1, or by the mounting bracket 23, the heat exchanger 21, the housing member 1 and the ventilation member 3. For example, the outlet chamber 18 on the leeward side 212 of the heat exchanger 21 may be defined by the mounting bracket 23, the heat exchanger 21 and the front cover plate 5, or by the mounting bracket 23, the heat exchanger 21 and the housing member 1. The ventilation component 3 supplies air to the air inlet cavity 17, and the air outlet cavity 18 exhausts air through the air outlet 15.

In some embodiments of the present invention, as shown in fig. 7 and 8, the mounting bracket 23 includes a flow deflector 231 and a water pan 232, the flow deflector 231 is disposed at the bottom of the heat exchanger 21, and the water pan 232 is disposed at the bottom of the flow deflector 231, wherein the cross-sectional shape of the upper end of the flow deflector 231 matches with the cross-sectional shape of the lower end of the heat exchanger 21, i.e., is the same or substantially the same, and is equal or close in size. From this, because installing support 23 is integrated with guide plate 231 and water collector 232 to make the condensate water that condenses on the heat exchanger 21 can directly drip into water collector 232, perhaps flow to guide plate 231 along heat exchanger 21 downwards, then get into water collector 232, and then play the effect that the condensate water was retrieved, improve air conditioner 100's reliability. In addition, the water pan 232 and the flow guide plate 231 are integrated on the mounting bracket 23, so that the structure compactness can be improved, and the additional arrangement of the water pan 232 and the like in the shell component 1 is avoided, thereby simplifying the structure and simplifying the production process.

In some embodiments of the present invention, as shown in fig. 7 and 8, the deflector 231 is curved from top to bottom to slant toward the front edge and is in smooth transition connection with the rear end of the drip tray 232. Thus, the air flow blown from below to above by the ventilation member 3 toward the air intake side of the heat exchanger 21 can be guided by the curved surface of the guide plate 231, thereby reducing the wind resistance.

In some embodiments of the present invention, as shown in fig. 7, the mounting bracket 23 is a single piece and further includes an upper end plate 233 located at the top of the heat exchanger 21 and two side plates 234 located at the left and right sides of the heat exchanger 21, and in conjunction with fig. 4 and 5, the front ends of the left and right sides of the heat exchanger 21 are respectively provided with an edge plate 213, and the edge plate 213 is connected with the rear end of the side plate 234 at the corresponding side.

Therefore, the mounting bracket 23 has a simple structure, is easily connected with the heat exchanger 21 and the housing member 1, does not interfere with the connection with the heat exchanger 21 and the housing member 1, and is easy to operate, and the mounting bracket 23 with the above structure is easily matched with the heat exchanger 21 and the like to jointly define the air outlet cavity 18.

From this, can utilize upper end plate 233 to form the top seal, avoid the air current from heat exchanger 21 top not through heat exchanger 21 heat transfer flow away, guarantee the heat transfer reliability, can utilize water collector 232 to play the bottom simultaneously and accept heat exchanger 21, the effect of the comdenstion water that electric auxiliary heat 22 dripped, avoid the comdenstion water to influence other part work, because installing support 23 is integrated with upper end plate 233 and water collector 232, thereby compare in setting up solitary upper seal plate and lower water installation at casing part 1 inside, can improve compact structure, the simplified assembly, and cost is reduced. Meanwhile, the upper mounting seat 2331 is arranged on the upper end plate 233 above the heat exchanger 21, the lower mounting seat 2322 is arranged in the water receiving tray 232 below the heat exchanger 21, and the upper end and the lower end of the electric auxiliary heater 22 are mounted, so that the influence of a mounting structure on the ventilation of the heat exchanger 21 can be reduced as much as possible, and the heat exchange reliability is improved.

In some alternative examples, as shown in fig. 4-5 and 7, the upper mounting seat 2331 may protrude upward from the upper end plate 233 with the upper end of the body portion 221 flush with or up beyond the upper end of the heat exchanger 21. Therefore, the temperature difference of upper and lower heat exchange can be reduced, and the consistency of the heat exchange temperature is improved.
