An air conditioner according to some embodiments of the present invention will be described below with reference to fig. 1 to 6.
Example one
As shown in fig. 1, 3 and 4, an embodiment of the first aspect of the present invention provides an air conditioner 100, where the air conditioner 100 includes: an indoor unit 110; an outdoor unit 120; and metal pipes 130 connecting the indoor unit 110 and the outdoor unit 120, wherein the metal pipes 130 are used for transmitting a refrigerant between the indoor unit 110 and the outdoor unit 120 and transmitting an electric signal between the indoor unit 110 and the outdoor unit 120.
The air conditioner 100 according to the present invention includes an indoor unit 110, an outdoor unit 120, and a metal duct 130. One end of the metal pipeline 130 is connected to the indoor unit 110, and specifically, is connected to a refrigerant pipeline in the indoor unit 110. The other end of the metal pipeline 130 is connected to the outdoor unit 120, and particularly, is connected to a refrigerant pipeline in the outdoor unit 120, so that a refrigerant heat exchange system is formed by the indoor unit 110, the outdoor unit 120, and the metal pipeline 130. In the operation process, the refrigerant is transmitted between the indoor unit 110 and the outdoor unit 120 through the metal pipe 130, and the refrigerant is evaporated or condensed in the indoor unit 110 to complete cooling or heating of the indoor environment.
In the related art, in addition to the refrigerant circulation pipeline, an electrical signal transmission line is connected between the indoor unit and the outdoor unit, so that the indoor unit and the outdoor unit can transmit operation information. Meanwhile, an electric power transmission line is generally disposed between the indoor unit and the outdoor unit, so that electric power is transmitted from the indoor unit to the outdoor unit or from the outdoor unit to the indoor unit through the electric power transmission line. However, in the production link, the electric signal transmission line and the electric energy transmission line need to be purchased independently, and the cost of the air conditioner is occupied. In the assembly link, the electric signal transmission line and the electric energy transmission line need to be assembled independently, and the requirement and the complexity of electric connection assembly are higher, so that the assembly difficulty and the assembly time consumption of the air conditioner are increased. And when connecting electric energy transmission line, there is the possibility of misconnection, and the misconnection probably damages the air conditioner and produces the potential safety hazard, leads to user's property safety and personal safety to receive the influence.
In contrast, in the present application, the metal pipe 130 is used as a refrigerant transmission medium, and the electric signal transmission between the outdoor unit 120 and the indoor unit 110 is completed through the conductive performance of the metal pipe 130, so that the problems in the related embodiments are solved. Specifically, communication signals may be transmitted between the indoor unit 110 and the outdoor unit 120 through the metal pipes 130, so that the indoor unit 110 and the outdoor unit 120 of the air conditioner 100 may cooperate. For example, the control command received by the indoor unit 110 can be transmitted to the outdoor unit 120 through the metal pipe 130, so as to control the outdoor unit 120 to perform corresponding operations according to the control command. Meanwhile, the operating condition information of the outdoor unit 120 may also be transmitted to one side of the indoor unit 110 through the metal pipe 130, so that a user may observe the operating parameters of the air conditioner 100 through a display device on the indoor unit 110, thereby providing convenience for controlling the operating mode of the air conditioner 100. Therefore, the present invention transmits the control signal through the metal pipeline 130 for transmitting the refrigerant, and the electric signal transmission line connecting the indoor unit 110 and the outdoor unit 120 can be omitted. Correspondingly, one of the indoor unit 110 and the outdoor unit 120 is connected to an external power source, and during operation, the electric energy can be transmitted to the other of the indoor unit 110 and the outdoor unit 120 through the metal pipeline 130, so as to meet the driving requirement of the electric energy. For example, the outdoor unit 120 is connected to an external power source, and the electric energy can be transmitted to the compressor in the outdoor unit 120 through the metal pipeline 130 to drive the compressor to work. Therefore, the power supply signal is transmitted through the metal pipeline 130 for transmitting the refrigerant, and an electric energy transmission line for connecting the indoor unit 110 and the outdoor unit 120 can be omitted. Therefore, the technical problems of high production cost, high assembly difficulty and poor reliability in the related technology are solved. And then realize optimizing the structure of air conditioner 100, compress the cost of air conditioner 100, reduce the assembly degree of difficulty of air conditioner 100 and consuming time, promote the technical effect of the security and the reliability of air conditioner 100.
The refrigerant flowing in the metal pipeline 130 is an insulating refrigerant, so that the refrigerant does not affect the electric control signal transmission and the power supply signal transmission of the metal pipeline 130, and the heat exchange structure in the indoor unit and the outdoor unit can be prevented from being damaged by the charged refrigerant.

Specifically, a first heat exchanger, a first controller 122, and a first communication line 123 are disposed in the outdoor unit 120. The first heat exchanger provides a heat exchange space for the refrigerant outdoors, and the refrigerant is evaporated or condensed in the first heat exchange assembly 121. The first controller 122 can be used to control the first heat exchanging assembly 121, the compressor, the throttle valve, and other electrical components in the outdoor unit 120 to work, so as to complete power adjustment or function switching of the outdoor unit 120 through the first controller 122. The first communication line 123 is a line inside the outdoor unit 120, and the first communication line 123 connects the first controller 122 and the metal pipe 130. During operation, the communication signal in the indoor unit 110 is transmitted to the outdoor unit 120 through the metal pipe 130, and then the communication signal is transmitted to the first controller 122 through the first communication line 123. The communication signal may include a control command, and the control command may be used to control the internal structure of the outdoor unit 120, such as the first heat exchange assembly 121, to adjust power or switch the operation mode. That is, the present invention eliminates the communication line between the indoor unit and the outdoor unit in the related art by providing the metal pipe 130 capable of transmitting the electric signal between the indoor unit 110 and the outdoor unit 120. Therefore, the technical problems of high production cost, high assembly difficulty and poor reliability in the related technology are solved. And then realize optimizing the structure of air conditioner 100, compress the cost of air conditioner 100, reduce the assembly degree of difficulty of air conditioner 100 and consuming time, promote the technical effect of the security and the reliability of air conditioner 100.

In the air conditioner 100, the outdoor unit 120 has a larger power demand than the indoor unit 110, and this difference in power demand is particularly significant in a multi-split central air conditioner. The power supply assembly 124 is disposed inside the outdoor unit 120, which helps to reduce the amount of power transmitted through the metal pipeline 130, so that the electrical parameters of the metal pipeline 130 can be kept within a safe range, and high-energy transmission failures such as breakdown and fire of the metal pipeline 130 can be avoided. Meanwhile, when the embodiment is applied to the central air conditioner, the power supply assembly 124 is disposed in the outdoor unit 120 to provide convenience for power distribution of the plurality of indoor units 110, thereby reducing the complexity of the central air conditioning system.
