The air conditioner performs a refrigeration cycle of the air conditioner by using a compressor, a condenser, an expansion valve, and a heat exchanger. The refrigeration cycle includes a series of processes involving compression, condensation, expansion, and evaporation, and supplies refrigerant to the air that has been conditioned and heat-exchanged.

The compressor compresses a refrigerant gas in a high-temperature and high-pressure state and discharges the compressed refrigerant gas. 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 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 heat exchanger may achieve a cooling effect by exchanging heat with a material to be cooled using latent heat of evaporation of a refrigerant. The air conditioner can adjust the temperature of the indoor space throughout the cycle.

The air conditioner includes an indoor air conditioner and an outdoor air conditioner, the outdoor air conditioner refers to a portion of a refrigeration cycle including a compressor and an outdoor heat exchanger, the indoor air conditioner includes an indoor heat exchanger, and an expansion valve may be provided in the indoor or outdoor unit. The indoor unit of the air conditioner is connected to an outdoor unit installed in an outdoor space through a pipe. The outdoor unit may be provided with a compressor, an outdoor heat exchanger, an outdoor fan, an expander, and the like for a refrigeration cycle, and the indoor unit may be provided with an indoor heat exchanger and an indoor fan.

The indoor heat exchanger and the outdoor heat exchanger serve as a condenser or a heat exchanger. When the indoor heat exchanger is used as the condenser, the air conditioner is used as a heater for a heating mode, and when the indoor heat exchanger is used as the heat exchanger, the air conditioner is used as a cooler for a cooling mode.

The present application proposes an air conditioning indoor unit, which is described in detail below with reference to the drawings.

As shown in fig. 1 to 3 and fig. 4a to 4d, in one embodiment of the air conditioning indoor unit provided by the present application, the air conditioning indoor unit includes:

the heat exchanger comprises a machine shell 1, wherein a heat exchange air duct 10 is formed in the machine shell 1, and an indoor air inlet 101 and an indoor air outlet 102 are formed in the machine shell 1;

the indoor heat exchanger assembly 2 includes:

the heat exchanger comprises a heat exchanger body 21 made of a section of heat exchanger, wherein the heat exchanger body is provided with a bending part 211, and only one bending part 211 is arranged. For example, the heat exchanger body can be made of a straight piece heat exchanger through a bending process.

The integrated arrangement of the heat exchanger can improve the manufacturing and assembling efficiency and is beneficial to the process improvement.

The casing can form the integral appearance of the indoor unit of the double-through-flow air conditioner. In the present example, the air conditioning indoor unit is generally cylindrical. The indoor unit of the air conditioner can be in the forms of a cylinder, a square column, an irregular column and the like. Indoor air enters the air inlet duct from the indoor air inlet, then enters the air outlet duct through the indoor heat exchanger, and then is discharged through the indoor air outlet. Indoor air enters the air-conditioning indoor unit from the indoor air inlet, exchanges heat with the indoor heat exchanger assembly at the indoor heat exchanger assembly, and the air after heat exchange is blown out of the air-conditioning indoor unit from the indoor air outlet through the indoor fan.

As shown in fig. 13, in some embodiments, the first air deflector 711 includes: the first portion 7111 and the second portion 7112 are connected to each other, the first portion 7111 and the second air guiding plate 712 are disposed opposite to each other, the second portion 7112 and the third air guiding plate 713 are disposed opposite to each other, and an included angle between an extending direction of the first portion 7111 and an extending direction of the second portion 7112 is an acute angle.

The utility model discloses an extension direction of machine in air conditioning sets up the extending direction of two parts of first aviation baffle into the acute angle, has reduced the air-out angle of air-out subassembly 7 for can realize forward blowing, can prevent again from the wind direct-blowing user that the indoor air outlet is seen off, can realize encircling the formula air supply through first portion and the second portion that is the angle setting again, satisfied user's user demand, improved user and used and experienced.

As shown in fig. 1 and 11, the indoor air outlet 102 includes a first air outlet 1021 and a second air outlet 1022 which are arranged side by side; the first air outlet 1021 corresponds to the fifth air duct 701, and the second air outlet 1022 corresponds to the sixth air duct 702. Because the first air guide plate 711 is arranged at an acute angle, when the air conditioner indoor unit is used, the air outlets on the front panel are distributed on two sides when viewed from the front, so that no obvious air outlet exists, and the visual effect is good.

Finally, it should be noted that: the embodiments in the present description are described in a progressive manner, each embodiment focuses on differences from other embodiments, and the same and similar parts among the embodiments are referred to each other.

The above embodiments are only used to illustrate the technical solution of the present invention and not to limit it; although the present invention has been described in detail with reference to preferred embodiments, it should be understood by those skilled in the art that: the invention can be modified or equivalent substituted for some technical features; without departing from the spirit of the present invention, it should be understood that the scope of the claims is intended to cover all such modifications and variations.
