Referring to Fig. 2 and Fig. 3, the air-conditioning indoor cabinet machine provided by the embodiment of the present utility model includes a housing 1, and the housing 1 is provided with an air inlet 11 and an air outlet 12, and the housing 1 is formed with a The air inlet duct 13, the evaporator chamber 14, and the air outlet duct 15 connected in sequence from bottom to top, the air inlet 11 communicates with the air inlet duct 13, and the air outlet 12 communicates with the air outlet duct 15 connected, the air intake duct 13 is provided with an air intake fan 2, the evaporator chamber 14 is provided with an evaporator 3, and an axial flow fan 4 is provided above the evaporator 3, and the axial flow fan The axis of 4 extends vertically, and the air inlet side of the axial flow fan 4 is opposite to the air outlet side of the evaporator 3 .

In the air-conditioning indoor cabinet machine provided by the embodiment of the utility model, since the air inlet fan 2 is arranged under the evaporator 3, and the axial flow fan 4 is arranged above the evaporator 3, the air inlet side of the axial flow fan 4 is connected to the evaporation The outlet side of device 3 is opposite. Therefore, the air intake fan 2 draws in air from the air inlet 11, and sends it upward to the evaporator 3 for heat exchange through the air intake duct 13, and the wind passing through the evaporator 3 is accelerated again under the action of the axial flow fan, thereby The wind speed passing through the upper section of the evaporator 3 is increased to improve the heat exchange efficiency of the evaporator 3 .

Wherein, the air inlet fan 2 may be an axial fan, a centrifugal fan or a cross-flow fan. Preferably, as shown in Fig. 5 and Fig. 6, the air inlet fan 2 can be a double-suction centrifugal fan, and there are two air inlets 11, and the two air inlets 11 are respectively connected to the double-suction centrifugal fan. The two air inlet sides are opposite to each other. As a result, air can be taken in from the two air inlets 11 at the same time, so that the air volume is increased and the heat exchange efficiency is improved. Specifically, as shown in Figure 6, the double-suction centrifugal fan includes a volute 21, a motor 22, an impeller 23 and a motor bracket 24, the volute 21 is used to form the air inlet duct 13, and the volute 21 is installed on the base 9 , the impeller 23 is arranged in the volute 21, the motor 22 is used to drive the impeller 23 to rotate, the motor 22 is installed on the motor bracket 24, and the motor bracket 24 is fixed at the air inlet of the volute 21. In addition, as shown in FIG. 6 , air intake grilles 111 are provided at the two air inlets 11 , and an air guide ring 211 is also provided at the air inlet of the volute 21 .

In order to achieve multi-angle and large-scale air supply, as shown in Figure 2, two air outlets 12 can be arranged side by side, and two guide grilles 5 that can swing laterally are respectively provided in the two air outlets 12. . Thus, in the process of lateral swinging, the guide grille 5 can change the horizontal direction of the air supply to increase the range of the air supply, and since the two guide grilles 5 are respectively controlled by the two driving devices, the The two guiding grilles 5 swing laterally independently. Thus, the air supply ranges of the two air outlets 12 can be adjusted independently, so that the air supply angles are more diverse and meet different user needs. Moreover, in this embodiment, since the two air outlets 12 are arranged separately, mixed flow can be avoided.

In another embodiment of the present application, only one air outlet 12 can be provided, and two air guide grilles 5 arranged side by side in one air outlet 12 can also realize diversified adjustment of the air supply angle. In this embodiment, since only one air outlet 12 is provided, the manufacturing process is simpler.

In order to increase the air purification function of the air conditioner, as shown in Figure 6, it is preferable to install a formaldehyde removal module 6 on the air path, specifically, the formaldehyde removal module 6 can be arranged at the air inlet 11, so that it can Formaldehyde is filtered to prevent formaldehyde from adhering to the evaporator 3 and causing secondary pollution.

Since the air supply direction is vertical and the air outlet direction is horizontal, the resistance to the wind when turning is relatively large, which will affect the air outlet speed. In order to overcome the above problems, as shown in Fig. 3 and Fig. 6, it is preferable to set a curved air guide 151 in the air outlet duct 15, one end of the air guide 151 is opposite to the air outlet side of the axial flow fan 4, and the other end is Opposite to the air outlet 12 , the bending part of the air guide 151 forms an arc-shaped transition surface. Therefore, the arc-shaped transition surface can make the transition of the wind direction smooth, and the wind outlet resistance is reduced, thereby ensuring the wind outlet speed.

Specifically, the air guide 151 can be a metal part, a plastic part, etc. Preferably, the air guide 151 is formed of a foam material, which is low in cost and has a thermal insulation effect, thereby effectively preventing cold loss.

In order to realize large-scale air supply, as shown in Fig. 2 and Fig. 6, the housing 1 includes a fixed part 16 and a rotating part 17 arranged on the upper end of the fixed part 16, and the rotating part 17 can be relative to the fixed part. Part 16 rotates, the air inlet duct 13 and the evaporator cavity 14 are located in the fixed part 16, the air outlet duct 15 is located in the rotating part 17, and the air outlet 12 is opened on the rotating part 17 . As a result, the air outlet 12 can rotate with the rotating part 17 to realize a large-scale air supply in the room. When the air outlet 12 is provided with a guide grille 5, the air supply range can be larger and a 360° air supply can be realized. .

In the embodiment of the present application, the evaporator 3 may adopt a flat, V-shaped or A-shaped structure. Since the heat dissipation area of the V-shaped evaporator 3 is larger, the V-shaped evaporator 3 is preferably used, and since the condensed water will condense on the surface of the evaporator 3, in order to prevent the condensed water from flowing into the air intake duct 13 below, as As shown in FIG. 6 , preferably, a water receiving tray 7 is provided at the bottom of the evaporator 3 to allow condensed water to flow into the water receiving tray 7 . In order to prevent the external air from exchanging heat with the gas in the evaporator cavity 14, as shown in Figure 6, thermal insulation foam 8 can be arranged on both sides of the V-shaped evaporator 3, thereby enhancing the thermal insulation effect of the evaporator cavity 14 and preventing cold volume loss.

Among them, there are many ways to install the axial flow fan 4 . The axial flow fan 4 can be directly connected to the upper end of the evaporator 3 , or the axial flow fan 4 can be fixed to the inner wall of the housing 1 above the evaporator 3 . Since there are heat dissipation structures (such as fins) on the evaporator 3, direct fixing on the evaporator 3 may damage these heat dissipation structures. Therefore, as shown in FIG. on the inner wall of housing 1. Specifically, the motor 42 of the axial flow fan 4 can be installed on the mounting plate 41 .

In order to reduce the wind resistance of the mounting plate 41 , as shown in FIG. 6 , the mounting plate 41 is preferably configured as a hollow structure. Thus, the wind can pass through the hollow structure of the mounting plate 41 , thereby reducing the wind resistance of the mounting plate 41 and increasing the wind speed.
