In the present application, the air conditioning indoor unit performs a refrigeration cycle of an air conditioning case by using a compressor, a condenser, an expansion valve, and an indoor heat exchanger. The refrigeration cycle includes a series of processes involving compression, condensation, expansion, and evaporation, and supplies a refrigerant to the air that has been conditioned and heat exchanged. The compressor compresses refrigerant gas in a low-temperature and low-pressure state and discharges refrigerant gas in a high-temperature and high-pressure state. The discharged refrigerant gas flows into the condenser. The condenser condenses the compressed refrigerant into a liquid phase, and heat is released to the surrounding environment through the condensation process. The expansion valve expands the liquid-phase refrigerant in a high-temperature and high-pressure state condensed in the condenser into a low-pressure liquid-phase refrigerant. The indoor heat exchanger evaporates the refrigerant expanded in the expansion valve and returns the refrigerant gas in a low temperature and low pressure state to the compressor. The indoor heat exchanger may achieve a cooling effect by exchanging heat with a material to be cooled using latent heat of vaporization of a refrigerant. The air conditioning case can adjust the temperature of the indoor space throughout the cycle. The outdoor unit of the air conditioner case refers to a portion of the refrigeration cycle including a compressor and an outdoor heat exchanger, the indoor unit of the air conditioner case includes an indoor heat exchanger, and an expansion valve may be provided in the indoor unit or the outdoor unit. The indoor heat exchanger and the outdoor heat exchanger function as a condenser or an indoor heat exchanger. When the indoor heat exchanger is used as a condenser, the air-conditioning case serves as a heater of the heating mode, and when the indoor heat exchanger is used as the indoor heat exchanger, the air-conditioning case serves as a cooler of the cooling mode.

Hereinafter, embodiments of the present application will be described in detail with reference to the accompanying drawings.

As shown in fig. 1 to 5, in one exemplary embodiment of the indoor heat exchanger of the present utility model, the indoor heat exchanger includes: the air conditioner comprises a shell 100, an air conditioner fan 200, an indoor heat exchanger 300 and a grille 400, wherein an air conditioner air outlet 102 and an air conditioner air inlet 101 are formed in the shell 100; the air-conditioning fan 200 is disposed in the housing 100, and the air-conditioning fan 200 is used for conveying air-conditioning air into the room through the air-conditioning air outlet 102; the indoor heat exchanger 300 is provided in the casing 100, and heat exchange is performed between the refrigerant flowing inside the indoor heat exchanger 300 and air to form a heating cycle or a cooling cycle; the grille 400 comprises a frame 401 and at least one first air deflector 402, wherein the frame 401 is arranged at an air inlet of the air conditioner, the first air deflector 402 is arranged in the frame 401, and the length direction of the first air deflector 402 is the same as the length direction of the indoor heat exchanger; the first air guide plate 402 is inclined from one side toward the air conditioner fan 200 toward the indoor heat exchanger 300; the air conditioner fan 200 guides air passing through the grille 400 by the first air guide plate 402, then passes through the indoor heat exchanger 300, and the air passing through the indoor heat exchanger 300 is output through the air conditioner air outlet 102.

In the above scheme, the air entering the housing 100 is guided to the indoor heat exchanger by the first air guide plate 402, so that the air flow can uniformly pass through the indoor heat exchanger 300, and the overall heat exchange effect of the air conditioner is ensured.

Referring to fig. 1 to 4, in some embodiments, an air conditioner air inlet 101 is formed at the top of the housing 100, and an indoor heat exchanger 300 is disposed between the air conditioner fan 200 and the air conditioner air inlet 101. The air conditioner air outlet 102 is formed at the bottom of the indoor side of the housing 100, and the air conditioner fan 200 is disposed between the indoor heat exchanger 300 and the air conditioner air outlet 102. After the air conditioning fan 200 is started, indoor air enters the shell 100 through the air conditioning air inlet 101 at the top of the shell 100 under the action of negative pressure, and the air forms air conditioning air after heat exchange through the indoor heat exchanger 300 and is output from the air conditioning air outlet 102.

Referring to fig. 2 and 4, in some embodiments, the indoor heat exchanger 300 includes a first heat exchange section 301, a second heat exchange section 302, and a third heat exchange section 303 connected in sequence along a width direction thereof; the first air deflector 402 is provided with two air deflectors respectively close to the first heat exchange section 301 and the third heat exchange section 303; a first air deflector 402 adjacent to the first heat exchange section 301, which is inclined from a side toward the air conditioner fan 200 toward the first heat exchange section 301; the first air deflector 402 near the third heat exchanging section 303 is inclined from a side toward the air conditioner fan 200 toward the third heat exchanging section 303. The indoor heat exchanger 300 is three-stage, and when the air flow passes through the first air deflector 402, the air flow passes through the first air deflector 402 in an inclined direction so as to flow to the first heat exchange section 301 or the third heat exchange section 303 respectively, so that the air flow can uniformly pass through the indoor heat exchanger 300.

In some embodiments, the air conditioner is a hanging type air conditioner, so the long direction of the housing 100 is horizontally disposed, and the long direction of the indoor heat exchanger 300 is the same as the long direction of the housing 100. The length direction of the first heat exchange section 301, the second heat exchange section 302, and the third heat exchange section 303 is the same as the length direction of the case 100.

Referring to fig. 1 to 4, in some embodiments, a side of the housing 100 near the room is a front panel. The width direction of the first heat exchange section 301 is vertical, the first heat exchange section 301 is arranged on one side of the second heat exchange section 302 close to the front panel, and one side of the second heat exchange section 302 close to the front panel is connected with the top of the first heat exchange section 301. The second heat exchange section 302 is inclined from bottom to top in a direction away from the front panel, one side of the third heat exchange section 303 close to the front panel is connected with the top of the second heat exchange section 302, and the third heat exchange section 303 is inclined from top to bottom in a direction away from the front panel. The second heat exchange section 302 is closest to the air conditioner air intake 101, so the amount of air flow into the second heat exchange section 302 is maximum. The first air deflector 402 adjacent to the first heat exchange section 301 deflects the air such that the air flow reaches the gap between the first heat exchange section 301 and the front panel and exchanges heat through the first heat exchange section 301.

In some embodiments, to enhance the heat exchange effect of the indoor heat exchanger 300, the first heat exchange section 301, the second heat exchange section 302, and the third heat exchange section 303 are all the same in length and width.

In some embodiments, the first air deflection 402 proximate the first heat exchange section 301 is angled at the same angle as the second heat exchange section 302. The inclination angle of the first air deflectors 402 close to the third heat exchange section 303 is the same as that of the third heat exchange section 303, and the two first air deflectors 402 can more uniformly guide air flow to the positions of the first heat exchange section 301 and the third heat exchange section 303.

Referring to fig. 5 to 9, in some embodiments, the first air guiding plates 402 are provided in plurality, the first heat exchanging section 301 corresponds to the first air guiding plates 402, and the third heat exchanging section 303 corresponds to the first air guiding plates 402. The plurality of first air deflectors 402 direct the air flow to the first heat exchange section 301 and the third heat exchange section 303, respectively. Further improving the uniformity of the air flow passing through the indoor heat exchanger 300 and improving the overall heat exchange effect of the air conditioner.

In some embodiments, the greater the width of the first air deflection 402, i.e., the direction of the airflow, the better the airflow is theoretically directed. However, the larger the width of the first air deflection 402, the smaller the gap between the first air deflection 402 and the indoor heat exchanger 300, and the worse the air circulation effect. The width of the first air deflection 402 is thus adaptively set according to the conditions of different air conditioners.

In some embodiments, the width of the first air deflectors 402 and the number of the first air deflectors 402 are set according to the actual situation.

The second air deflection 403 directs the air flow at the second air deflection 403.

In some embodiments, the width of the second air deflection 403 is the same as the width of the first air deflection 402. When the air flow passes through the grille 400, the air flow can be uniformly reversed by the first air deflector 402 and the second air deflector 403 and respectively pass through the first heat exchange section 301, the second heat exchange section 302 and the third heat exchange section 303. Improving the heat exchange effect of the air flow.

In some embodiments, the indoor heat exchanger 300 has only two heat exchange sections, namely a first heat exchange section 301 and a third heat exchange section 303, the first heat exchange section 301 and the third heat exchange section 303 being connected to each other. The two first air deflectors 402 direct the air flow directly to the first heat exchange section 301 and the third heat exchange section 303.

Referring to fig. 5 to 9, in some embodiments, the minimum distance between the first air deflectors 402 and the frame 401 is greater than the distance between the two first air deflectors 402. The distance that the second heat exchange section 302 is close to the air conditioner air inlet 101 is relatively short, and the corresponding area of the second heat exchange section 302 and the air conditioner air inlet 101 is relatively large, so that when the grille 400 is not provided, the air quantity passing through the second heat exchange section 302 is relatively large. The two first air deflectors 402 are spaced directly apart from each other by a small distance so that the amount of air flow corresponding to the second heat exchange section 302 is small when the air enters the interior of the housing 100. And guides the air flow through the first air guide plate 402 to ensure uniform air flow passing through the indoor heat exchanger 300 and improve heat exchange effect.
