An air conditioner performs a cooling and heating cycle of the air conditioner by using a compressor, a condenser, an expansion valve, and an evaporator. The cooling and heating cycle includes a series of processes involving compression, condensation, expansion, and evaporation, and supplies a refrigerant medium 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 high-temperature and high-pressure liquid-phase refrigerant condensed in the condenser into a low-pressure liquid-phase refrigerant. The evaporator 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 evaporator can achieve a refrigerating effect by heat exchange 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 outdoor unit of the air conditioner refers to a portion of a refrigeration cycle including a compressor, an outdoor heat exchanger, and an outdoor fan, the indoor unit of the air conditioner includes a portion of an indoor heat exchanger and an indoor fan, and a throttling device (e.g., a capillary tube or an electronic expansion valve) may be provided in the indoor unit or the outdoor unit.
The indoor heat exchanger and the outdoor heat exchanger serve as a condenser or an evaporator. The air conditioner performs a heating mode when the indoor heat exchanger serves as a condenser, and performs a cooling mode when the indoor heat exchanger serves as an evaporator.
The indoor heat exchanger and the outdoor heat exchanger are switched to be used as a condenser or an evaporator, a four-way valve is generally adopted, and specific reference is made to the arrangement of a conventional air conditioner, which is not described herein again.
The refrigeration working principle of the air conditioner is as follows: the compressor works to enable the interior of the indoor heat exchanger (in the indoor unit, the evaporator at the moment) to be in an ultralow pressure state, liquid refrigerant in the indoor heat exchanger is rapidly evaporated to absorb heat, air blown out by the indoor fan is cooled by the coil pipe of the indoor heat exchanger to become cold air which is blown into a room, the evaporated and vaporized refrigerant is compressed by the compressor, is condensed into liquid in a high-pressure environment in the outdoor heat exchanger (in the outdoor unit, the condenser at the moment) to release heat, and the heat is dissipated into the atmosphere through the outdoor fan, so that the refrigeration effect is achieved by circulation.
The heating working principle of the air conditioner is as follows: the gaseous refrigerant is pressurized by the compressor to become high-temperature and high-pressure gas, and the high-temperature and high-pressure gas enters the indoor heat exchanger (the condenser at the moment), is condensed, liquefied and released heat to become liquid, and simultaneously heats indoor air, so that the aim of increasing the indoor temperature is fulfilled. The liquid refrigerant is decompressed by the throttling device, enters the outdoor heat exchanger (an evaporator at the moment), is evaporated, gasified and absorbs heat to form gas, absorbs the heat of outdoor air (the outdoor air becomes cooler) to form gaseous refrigerant, and enters the compressor again to start the next cycle.

Furthermore, in the rotation process of the second air guiding assembly 200, the second air guiding assembly may be deflected under the action of the driving gear 240, in order to improve the stability of the second air guiding assembly 200, a plurality of driven gears 260 are further arranged around the second air guiding assembly 200, and the plurality of driven gears 260 are circumferentially distributed on the outer side of the second air guiding assembly 200 and are in contact fit with the transmission gear of the second air guiding assembly 200.
When the driving gear 240 acts on the second wind guiding assembly 200, the second wind guiding assembly 200 is not displaced due to the action of the driven gear 260, so that the stability of the operation is ensured, and the limiting effect is achieved.
Preferably, in order to improve the safety of the device and prevent the second air guide assembly 200 from falling down due to a device failure and causing a safety hazard, a plurality of protection plates 250 are fixedly mounted on the mounting base plate, and the protection plates 250 are arc-shaped and are located between the adjacent driven gears 260 and the adjacent driving gears 240.
The working process is as follows:
two air guide assemblies and a first air guide assembly are sequentially arranged on the air outlet part of the air-conditioning indoor unit casing 100 along the output direction of the fluid, and the first air guide part 340 on the first air guide assembly 300 moves up and down relative to the casing 100 under the driving of the first driving part 320 and also swings.
The main flow direction of the air flow can be adjusted by lifting the first air guiding part 340, and compared with the traditional air guiding structure, the air guiding structure has the advantages that: in the ascending process of the first air guiding part 340, the first air guiding part 340 is of a gradually expanding structure along the air flow conveying direction, so that when fluid output from the air outlet part acts on the first air guiding surface, the fluid is conveyed around along the first air guiding surface, the effect that cold air is approximately horizontally discharged to realize settlement air supply is achieved, the comfort level is improved, hot air can be vertically supplied downwards in a descending manner, the rapid heating is achieved, and the use comfort level is improved.
In addition, the first air guiding part 340 also generates a swinging motion: when the first driving portions 320 on the first air guiding portion 340 are at different steps, the first air guiding portion 340 swings unidirectionally in a 3D space sinusoidal track, and also swings cyclically in a clockwise or counterclockwise direction alternately, so as to achieve uniform air supply around 360 degrees indoors and improve the uniformity of air supply indoors.
Second air guide component 200 and mounting panel separation under the effect of first response module and second response module, suspend in the mounting panel top, under the effect of second drive division, second air guide component 200 clockwise or anticlockwise variable speed rotates to realize the soft natural wind of better simulation.
The above examples are only intended to illustrate the technical solution of the present invention, but not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that various changes may be made and equivalents may be substituted for elements thereof; and such modifications or substitutions do not depart from the spirit and scope of the corresponding technical solutions.
