The present embodiment provides an air conditioner that 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.
First embodiment, referring to fig. 1, according to some embodiments of the present application, an air conditioner includes an indoor unit (not shown) installed in an indoor space. The indoor unit is connected to an outdoor unit installed in an outdoor space through a pipe. The outdoor unit includes a casing 1, a compressor (not shown), an outdoor heat exchanger 2, an outdoor fan 3, and other relevant components.
And for the outdoor unit, the outdoor unit can be hung on the outer wall through a hanging frame, and can also be installed outdoors through a base.
Meanwhile, the housing 11 is correspondingly provided with an air inlet and an air outlet. Under the action of the outdoor fan 3, outside air enters the shell 1 from the air inlet and exchanges heat with the outdoor heat exchanger 2, and the air after heat exchange is output from the air outlet.
In the practical use process, under the environment of winter, the outdoor environment temperature that the air conditioner heating faces is low, and traditional air conditioner is under the lower condition of ambient temperature, and condensing pressure can reduce very sharply, and the refrigerant pressure through throttling element also can descend, and the refrigerant pressure of outdoor heat exchanger also can correspondingly descend, and evaporating temperature reduces, if the temperature is less than freezing point temperature, then the condensate water that produces on the outdoor heat exchanger will freeze, causes the outdoor heat exchanger to freeze. At this time, the air conditioner can execute a defrosting mode, and the four-way valve is reversed, so that the indoor unit refrigerates and the outdoor unit heats.
However, the air conditioner in the defrosting mode causes a rapid drop in the indoor temperature. When the air conditioner is defrosted, the influence of the defrosting of the outdoor heat exchanger 2 on the indoor temperature is reduced. For this purpose, the outdoor unit is also provided with a microwave generator 4.
The microwave generated by the microwave generator 4 can propagate in the casing 1 and microwave-heat the frost layer on the surface of the outdoor heat exchanger 2 to perform the function of defrosting. Wherein, when the outdoor heat exchanger 3 is heated by the microwave generator 4 to defrost, the air conditioner executes a heating mode.
And the microwave generated by the microwave generator 4 is used for heating and defrosting the outdoor heat exchanger 2 in the shell 1 by microwave without switching modes by a four-way valve, so that the condition that the air conditioner has no indoor hot air supply when defrosting is needed is avoided, and the indoor unit is still in a normal heating mode while defrosting the outdoor heat exchanger.
In some embodiments of the present application, for the outer shell 1, the outer shell 1 is made of sheet metal parts, and a relatively closed microwave heating cavity is formed in the outer shell 1. Like this, utilize the shell 1 of panel beating material alright in order to reflect the microwave in inside to make the microwave distribution even. Meanwhile, the shell 1 can also effectively reduce the microwave leakage in the shell 1, thereby improving the use reliability.
In the second embodiment, as shown in fig. 2, after the microwaves generated by the microwave generator 4 are emitted into the casing 1, the microwaves have a certain directivity, and the microwave distribution is uneven, which tends to cause the phenomenon that the frost layer on the surface of the outdoor heat exchanger 2 is not completely frosted.
For this purpose, in another embodiment of the present application, a rotatable impeller 5 is disposed in the housing 1, and the impeller 5 is used for reflecting the microwave generated by the microwave generator 4.
In actual use, the microwave generated by the microwave generator 4 is injected into the housing 1, and the wave stirring blades rotate in the housing 1, so that the microwave in the housing 1 can be reflected (refer to the microwave indicated by the dotted line in fig. 1).
And the microwave is reflected through the wave stirring blade, so that the microwave can be dispersed in the shell 1, and the reflection effect of the shell 1 is configured, so that a more uniform microwave field is formed in the shell 1, and thus, the more uniform microwave heating defrosting operation can be performed on the outdoor heat exchanger 2.
Among them, in some embodiments of the present application, there are various ways to drive the impeller 5, such as: a separate drive may additionally be provided to drive the impeller 5 in rotation.
In order to reduce the manufacturing cost, the outdoor fan 3 may drive the wave stirring impeller 5 to rotate, and correspondingly, the outdoor fan 3 includes: a motor 21 and a fan 22, wherein the motor 21 is used for driving the fan 22 to rotate so as to enable the outside air to enter the shell 1 and exchange heat with the outdoor heat exchanger 2.
The motor 21 drives the fan 22 to rotate and simultaneously drives the impeller 5 to rotate synchronously. Correspondingly, the motor 21 has two rotating shafts (not labeled) coaxially arranged; the fan 22 is arranged on one of the rotating shafts, and the wave stirring impeller 5 is arranged on the other rotating shaft.
When the motor 21 is powered on, the stirring impeller 5 and the fan 22 are driven to rotate at the same time. Wherein, in the defrosting process, the stirring impeller 5 in the rotating process reflects the microwave which is emitted into the shell 1 by the microwave generator 4.
Meanwhile, when the wave stirring impeller 5 inside the casing 1 is used for reflecting microwaves, the wave stirring blades are coaxially arranged with the fan 22, so that the wave stirring blades can be used for additionally driving air inside the casing 1 to flow, and the heat exchange efficiency of the outdoor heat exchanger 2 is improved.
Specifically, for the wave stirring blade, the wave stirring blade generally comprises: a hub 51 and a plurality of blades 52; the hub 51 can rotate in the housing 1, that is, the hub 51 is mounted on the corresponding rotating shaft of the motor 21; a plurality of blades 52 are provided on the hub 51 around the axis of the hub 51; the microwave emitting port of the microwave generator 4 is located at the side of the blade 52.
The microwave emitted by the microwave generator 4 is emitted towards the wave stirring blade, and after being emitted towards the wave stirring blade, the microwave is reflected by the rotating wave stirring blade, so that the microwave is scattered into the shell 1.
And the surface of the blade 52 is arranged obliquely with respect to the axis of the hub 51 so that the reflecting surface of the blade 52 forms a non-right angle with the emitting direction of the microwave, thereby better reflecting the microwave.
In some embodiments of the present application, for the microwaves emitted by the microwave generator 4, by controlling the microwave emission angle of the microwave generator 4, part of the microwaves directly strike the outdoor heat exchanger 2, and part of the microwaves emitted by the microwave generator 4 strike the blades 52 and are reflected.
During actual assembly, the microwave generator 4 is arranged at a position opposite to the outdoor heat exchanger 2, so that a microwave emitting port of the microwave generator 4 faces the outdoor heat exchanger 2, and thus, microwaves can be directly and effectively emitted to the outdoor heat exchanger 2 to perform microwave heating defrosting.
And limited by the coverage area of the microwaves, part of the microwaves emitted from the microwave generator 4 are emitted to the wave stirring impeller 5, and then the microwaves are reflected by the wave stirring impeller 5, so that the microwaves are dispersed to each area inside the shell 1, dead angles are reduced or avoided, and the outdoor heat exchanger 2 can be used for defrosting more comprehensively.
In addition, as for the surface of the blade 52 arranged obliquely relative to the axis of the hub 51, the air in the casing 1 can be pushed towards the fan 22 better, so as to accelerate the air flow speed inside and outside the casing 1, and further improve the heat exchange efficiency of the outdoor heat exchanger 2.
In the third embodiment, as shown in fig. 3 to 4, in order to ensure that the outdoor heat exchanger 2 can receive the microwaves more uniformly, the microwaves generated by the microwave generator 4 are guided and transmitted by the microwave conducting member 6, and the position of the microwave conducting member can be changed in the housing 1 and used for transmitting the microwaves generated by the microwave generator 4.

In actual use, the microwave conducting part 6 can move in the casing 1 to perform effective microwave heating treatment on the whole outdoor heat exchanger 2. The movement of the microwave conducting part 6 includes, but is not limited to, sliding and rotating.
For the case that the microwave conducting component slides in the casing 1, for the outdoor heat exchanger 2 with a larger height dimension, the microwave emitting position of the microwave conducting component 6 is changed by lifting the microwave conducting component, so as to meet the microwave heating requirements of the outdoor heat exchanger 2 at different height positions. The second waveguide 62 indicated by a dotted line with reference to fig. 3 is moved downward to the second waveguide 62 indicated by a solid line.
For the microwave conducting part to rotate in the casing 1, the microwave conducting part is rotated for the outdoor heat exchanger 2 with larger width dimension, so that the outdoor heat exchanger 2 obtains the comprehensive microwave heating.

Specifically, in the actual assembly, the first waveguide 61 is directly connected to the microwave emitting port of the microwave generator 4, so that the microwaves emitted from the microwave generator 4 are transmitted through the first waveguide 61.
And since the second waveguide 62 is sleeved outside the first waveguide 61 and can move, the microwave enters the second waveguide 62 to be transmitted and finally injected into the interior of the housing 1. And under the action of the waveguide tube, the microwave heating requirements of the outdoor heat exchangers 2 in different areas can be met.
In some embodiments of the present application, the second waveguide 62 is reciprocally movable with respect to the first waveguide 61; and/or the second waveguide 62 may be rotatable with respect to the first waveguide 61. Of course, the second waveguide 62 can move relative to the first waveguide 61, and can also rotate relative to the first waveguide 61, so that the whole outdoor heat exchanger 2 can be covered by the microwaves more comprehensively and effectively, and the defrosting by microwave heating can be performed more thoroughly and effectively.
In other embodiments, the free end of the second waveguide 62 is provided with a plurality of microwave output ports 621 for outputting microwaves, so that the requirement of outputting microwaves in different directions simultaneously can be satisfied.
In other embodiments of the present application, in order to drive the second waveguide 62 to move, the microwave conducting component further comprises a driving component (not shown) for driving the second waveguide 62 to reciprocate and/or driving the second waveguide 62 to rotate.
Specifically, the driving means can provide a driving force to move the second waveguide 62 relative to the first waveguide 61.
