[0034] In the description of the present invention, "first feature" and "second feature" may include one or more such features.

[0035] In the description of the present invention, “multiple” means two or more, and “several” means one or more.

[0036] An air conditioner according to an embodiment of the present invention will be described below with reference to the accompanying drawings.

[0037] like Figure 1-Figure 3 As shown, the air conditioner according to the embodiment of the present invention may include an indoor unit.

[0038] The indoor unit may include an indoor fan, which may guide air into the indoor unit and increase the flow rate of the air.

[0039] The indoor unit may include an indoor heat exchanger. Driven by the indoor fan, the air can be guided to flow through the indoor heat exchanger so that the air can form a heat exchange airflow after heat exchange with the indoor heat exchanger, and then be discharged into the room to achieve indoor cooling or heating.

[0040] The indoor unit may include an indoor unit control board 400, which is electrically connected to the indoor fan and the indoor heat exchanger respectively. In this way, the indoor unit control board 400 can control the operation of the indoor fan and the indoor heat exchanger to adjust the speed of the indoor fan, and can adjust the power of the indoor heat exchanger, and then can adjust the heat exchange amount of the air exchanged with the indoor heat exchanger, thereby adjusting the cooling capacity or heating amount of the air conditioner.

[0041] The air conditioner may include an outdoor unit.

[0042] The outdoor unit may include a compressor that compresses low-pressure refrigerant into high-pressure refrigerant and then discharges the refrigerant to an indoor heat exchanger or an outdoor heat exchanger.

[0043] The outdoor unit may include an outdoor fan, which may guide outdoor air into the outdoor unit and increase the flow rate of the air.

[0044] The outdoor unit may include an outdoor heat exchanger. Driven by the outdoor fan, the outdoor air can be directed to the outdoor heat exchanger so that the refrigerant can exchange heat with the outdoor air through the outdoor heat exchanger. In this way, when the air conditioner is cooling the indoor room, the refrigerant flowing through the outdoor heat exchanger can release excess heat to the outdoor air through the outdoor heat exchanger, or when the air conditioner is heating the indoor room, the refrigerant flowing through the outdoor heat exchanger can absorb the heat of the outdoor air through the outdoor heat exchanger and then flow back to the compressor.

[0045] The outdoor unit may include an outdoor unit control panel 200, which is electrically connected to the compressor, outdoor fan and outdoor heat exchanger respectively. In this way, the outdoor unit control panel 200 can control the operation of the indoor compressor, indoor unit and indoor heat exchanger to adjust the power of the compressor, the speed of the outdoor fan and the power of the outdoor heat exchanger.

[0046] The air conditioner may include an online line 300, one end of the online line 300 is electrically connected to the indoor unit control panel 400, and the other end of the online line 300 is electrically connected to the outdoor unit control panel 200, so that the electrical connection between the indoor unit control panel 400 and the outdoor unit control panel 200 can be achieved. It can be understood that during actual installation, the distance between the outdoor unit and the indoor unit will be different, that is, the distance between the indoor unit control panel 400 and the outdoor unit control panel 200 will also be different. By connecting the indoor unit control panel 300 and the outdoor unit control panel 200, the connection can be made after the positions of the outdoor unit and the indoor unit are fixed. The connection is convenient and quick, and easy to assemble.

[0047] The air conditioner may further include a grounding wire 500, which is electrically connected to the outdoor control board 200 to ground the outdoor control board 200. In this way, the outdoor control board 200 can lead the current on the charged metal to the ground through the grounding wire 500, so that the air conditioner can operate normally and provide personal safety protection.

[0048] Among them, the external unit control board 200 may include a first terminal block 210, the other end of the online line 300 is connected to the first terminal block 210, and the first terminal block 210 is provided with at least a first live wire terminal position 211, a first neutral wire terminal position 212, a first communication line terminal position 213 and a first ground wire terminal position 214, and the first ground wire terminal position 214 is electrically connected to the ground wire 500.

[0049] It should be noted that in the related art, the live wire, neutral wire, communication wire and ground wire need to be led out separately and then transferred to the terminal block, and then connected to the online line 300 through the terminal block. In the embodiment of the present utility model, the external unit control board 200 can be directly connected to the online line 300 through the first terminal block 210, and the first terminal block 210 has more integrated wiring positions, which further simplifies the connection method between the internal unit control board 400 and the external unit control board 200, and the connection is more convenient and quick.

[0050] Among them, the online line 300 can include a live wire connection line 310, a neutral wire connection line 320, a communication line connection line 330 and a ground wire connection line 340, and the live wire connection line 310 is correspondingly connected to the first live wire connection position 211, the neutral wire connection line 320 is correspondingly connected to the first neutral wire connection position 212, the communication line connection line 330 is correspondingly connected to the first communication line connection position 213, and the ground wire connection line 340 is correspondingly connected to the first ground wire connection position 214.

[0051] This arrangement not only simplifies the connection steps between the indoor unit control board 400 and the outdoor unit control board 200, but also the indoor unit control board 400 can be directly connected to the first ground wire connection position 214 on the first terminal block 210 through the online line 300, so that the indoor unit control board 400 does not need to be separately set up and then set up a ground wire for grounding. When the online line 300 and the first terminal block 210 are connected, the ground wire 500 and the online line 300 are respectively electrically connected to the first ground wire connection position 214, so that the indoor unit control board 400 and the outdoor unit control board 200 can be grounded only through one ground wire 500 to achieve a common ground. The grounding connection method of the indoor unit control board 400 and the outdoor unit control board 200 is simpler, which is conducive to simplifying the grounding connection steps of the indoor unit control board 400 and the outdoor unit control board 200, and can reduce the number of grounding wire harnesses of the air conditioner, further improving the wiring and assembly efficiency of the whole machine, and facilitating maintenance and assembly.

[0052] In this way, the air conditioner according to the embodiment of the present invention can simplify the structure of the outdoor control panel 200, and thus simplify the connection between the outdoor control panel 200 and the indoor control panel 400. After the outdoor control panel 200 and the indoor control panel 400 are connected, they only need to be grounded through a grounding wire 500, and the grounding connection method is more convenient and simple.

[0053] In some specific embodiments of the present invention, Figure 1 As shown, the grounding wire 500 is plug-connected and / or welded to the outdoor unit control board 200 to electrically connect the grounding wire 500 to the ground branch 225 of the outdoor unit control board 200 .

[0054] That is to say, the grounding wire 500 and the external unit control board 200 can be connected by plugging, for example, by plug-in connection. This helps to simplify the connection method between the grounding wire 500 and the external unit control board 200, facilitates the disassembly and assembly between the grounding wire 500 and the external unit control board 200, and helps to improve the assembly efficiency between the grounding wire 500 and the external unit control board 200.

[0055] Alternatively, the grounding wire 500 and the outdoor unit control board 200 can also be connected by welding, that is, the grounding wire 500 can be directly fixedly connected to the outdoor unit control board 200. This is conducive to improving the connection reliability of the grounding wire 500 and the outdoor unit control board 200, thereby making the electrical connection between the grounding wire 500 and the ground branch 225 more stable and reliable, further ensuring that the air conditioner can operate normally and can better protect personal safety.

[0056] In some specific embodiments of the present invention, Figure 1 and Figure 3 As shown, the outdoor unit control board 200 may include a board 220, on which a circuit 221 is provided. The circuit 221 may include at least a live wire branch 222, a neutral wire branch 223, a communication wire branch 224, and a ground wire branch 225. Specifically, the live wire L and the neutral wire N can provide operating power for the air conditioner, and the ground wire connection provides safety protection. The indoor unit control board 400 can transmit communication commands to the outdoor unit control board 200 via the communication line S1.

[0057] In addition, the external unit control board 200 may include a three-wire inductor 226 , which is electrically connected to the live branch 222 , the neutral branch 223 and the communication branch 224 , respectively. The three-wire inductor 226 and the ground branch 225 are electrically connected to the first wiring socket 210 , respectively.

[0058] That is to say, a three-wire inductor 226 can be added to the front end of the AC filter input circuit and the outdoor communication circuit, and the live wire branch 222, the neutral wire branch 223 and the communication line branch 224 can be electrically connected to the first terminal block 210 through a three-wire inductor 226, so that the live wire branch 222, the neutral wire branch 223 and the communication line branch 224 do not need to be separately led out and connected to the first terminal block 210, and the three-wire inductor 226 can replace the magnetic ring, which not only simplifies the structure of the outdoor unit control board 200, but also optimizes the electromagnetic interference characteristics of the circuit 221.

[0059] In some specific embodiments of the present invention, Figure 3 As shown, the three-wire inductor 226 is welded to the board 220. This arrangement not only improves the connection strength between the three-wire inductor 226 and the board 220, making the connection between the three-wire inductor 226 and the board 220 more stable and reliable, but also simplifies the connection between the three-wire inductor 226 and the board 220, facilitating processing and assembly.

[0060] Thus, by electrically connecting the other end of the online line 300 to the first terminal block 210, the online line 300 can be electrically connected to the three-wire inductor 226 and the ground branch 225, so that the online line 300 can be electrically connected to the live branch 222, the neutral branch 223, and the communication branch 224 on the external unit control board 200. The stability of the electrical connection between the online line 300 and the live branch 222, the neutral branch 223, and the communication branch 224 can be improved, and the connection method is simpler, more reliable, and easier to assemble.

[0061] In some embodiments of the present invention, the terminal block is a socket fixed to the plate body 220, and the other end of the connection cable 300 is plugged into the socket. Thus, the other end of the connection cable 300 can be directly plugged into the socket to electrically connect the connection cable 300 to the external unit control board 200. This simplifies the connection between the connection cable 300 and the external unit control board 200, simplifies assembly, and improves assembly efficiency.

[0062] In some specific embodiments of the present invention, Figure 2 As shown, the socket may include a plurality of jacks, which are arranged at intervals and correspond one to one with the first live wire connection position 211, the first neutral wire connection position 212, the first communication line connection position 213 and the first ground wire connection position 214 respectively.

[0063] The central axes of the plurality of jacks are all perpendicular to the plate body 220 .

[0064] In this way, when the other end of the online cable 300 is inserted into the socket, the live wire branch 222, the neutral wire branch 223, the communication line branch 224 and the ground wire branch 225 can be respectively connected to the corresponding wire harness of the online cable 300 to ensure the accuracy and convenience of the connection between the online cable 300 and the first terminal block 210.

[0065] Moreover, the central axes of the multiple jacks are all perpendicular to the plate body 220, that is, the socket of the embodiment of the present invention can be a vertical socket. When the online line 300 is connected to the jack, the plate body 220 can support the socket from the side of the socket facing away from the online line 300, so that the socket and the plate body 220 are not easy to move relative to each other, that is, the external unit control board 200 is not easy to be damaged, which is beneficial to improve the service life of the external unit control board 200.

[0066] In some specific embodiments of the present invention, Figure 2 As shown, the socket may include a plurality of jacks, which are spaced apart and correspond to the first live wire connection position 211, the first neutral wire connection position 212, the first communication line connection position 213, and the first ground wire connection position 214. The central axes of the plurality of jacks are parallel to the plate body 220.

[0067] In this way, when the other end of the online cable 300 is inserted into the socket, the live wire branch 222, the neutral wire branch 223, the communication line branch 224 and the ground wire branch 225 can be respectively connected to the corresponding wire harness of the online cable 300 to ensure the accuracy and convenience of the connection between the online cable 300 and the first terminal block 210.

[0068] Moreover, the central axes of the multiple jacks are all parallel to the board body 220, that is, the socket of the embodiment of the utility model can be a horizontal socket, which is convenient for the layout and installation of the external unit control board 200 to save the internal space of the outdoor unit, and facilitates the plug-in connection of the online line 300 and the socket, so that the electrical connection between the online line 300 and the external unit control board 200 is more convenient and easy to assemble.

[0069] In some specific embodiments of the present invention, the indoor unit control board 400 may include a second wiring socket, and one end of the connection line 300 is provided with a plug, and the plug is plugged into the second wiring socket.

[0070] For example, the second terminal block can also be constructed as a socket, so that the plug connected to one end of the online cable 300 can be plugged into the second terminal block once, so that the online cable 300 can be electrically connected to the indoor unit control board 400, and the connection method between the online cable 300 and the indoor unit control board 400 can be simplified, making assembly easier.

[0071] In some specific embodiments of the present invention, Figure 1 As shown, the indoor unit control panel 400 may include a second wiring socket, which is provided with at least a second live wire wiring position 411 , a second neutral wire wiring position 412 , a second communication line wiring position 413 and a second ground wire wiring position 414 .

[0072] The connection line 300 may include a live line 310, a neutral line 320, a communication line 330, and a ground line 340. The live line 310, the neutral line 320, the communication line 330, and the ground line 340 are plugged and connected to the second live line connection position 411, the second neutral line connection position 412, the second communication line connection position 413, and the second ground line connection position 414, respectively.

[0073] For example, the online line 300 can be connected to the second terminal block through a plug, that is, the live wire connection line 310 can be plugged into the second live wire terminal position 411 alone, the neutral wire connection line 320 can be plugged into the second neutral wire terminal position 412 alone, the communication line connection line 330 can be plugged into the second communication line terminal position 413 alone, and the ground wire connection line 340 can be plugged into the second ground wire terminal position 414 alone.

[0074] With this arrangement, there are more ways to connect the online cable 300 and the second terminal block on the indoor unit control board 400, that is, one end of the online cable 300 can be plugged into the second terminal block at one time, or the live wire connection line 310, neutral wire connection line 320, communication wire connection line 330 and ground wire connection line 340 of the online cable 300 can be plugged into different wiring positions separately, so that it is convenient to set it according to the specific structure of the indoor unit, and the layout setting can be more diversified.

[0076] The air conditioner according to the embodiment of the present invention may include an indoor unit.

[0077] The indoor unit may include an indoor fan, which may guide air into the indoor unit and increase the flow rate of the air.

Driven by the indoor fan, the air can be guided to flow through the indoor heat exchanger so that the air can form a heat exchange airflow after heat exchange with the indoor heat exchanger, and then be discharged into the room to achieve indoor cooling or heating.

[0079] The indoor unit may include an indoor unit control board 400, which is electrically connected to the indoor fan and the indoor heat exchanger respectively. In this way, the indoor unit control board 400 can control the operation of the indoor fan and the indoor heat exchanger to adjust the speed of the indoor fan, and can adjust the power of the indoor heat exchanger, and then can adjust the heat exchange amount of the air exchanged with the indoor heat exchanger, thereby adjusting the cooling capacity or heating amount of the air conditioner.

[0083] The outdoor unit may include an outdoor heat exchanger. Driven by the outdoor fan, the outdoor air can be directed to the outdoor heat exchanger so that the refrigerant can exchange heat with the outdoor air through the outdoor heat exchanger. In this way, when the air conditioner is cooling the indoor room, the refrigerant flowing through the outdoor heat exchanger can release excess heat to the outdoor air through the outdoor heat exchanger, or when the air conditioner is heating the indoor room, the refrigerant flowing through the outdoor heat exchanger can absorb the heat of the outdoor air through the outdoor heat exchanger and then flow back to the compressor.

[0084] The outdoor unit may include an outdoor unit control panel 200, which is electrically connected to the compressor, outdoor fan and outdoor heat exchanger respectively.

It can be understood that during actual installation, the distance between the outdoor unit and the indoor unit will be different, that is, the distance between the indoor unit control panel 400 and the outdoor unit control panel 200 will also be different. By connecting the indoor unit control panel 300 and the outdoor unit control panel 200, the connection can be made after the positions of the outdoor unit and the indoor unit are fixed. The connection is convenient and quick, and easy to assemble.

[0086] The air conditioner may further include a grounding wire 500, which is electrically connected to the outdoor control board 200 to ground the outdoor control board 200. In this way, the outdoor control board 200 can lead the current on the charged metal to the ground through the grounding wire 500, so that the air conditioner can operate normally and provide personal safety protection.

[0087] Among them, the external unit control board 200 may include a first terminal block 210, the other end of the online line 300 is connected to the first terminal block 210, the first terminal block 210 is provided with multiple wiring positions, the multiple wiring positions include at least a ground wiring position, and the ground wiring position is electrically connected to the ground wire 500.

[0088] Such an arrangement is conducive to simplifying the connection steps between the indoor unit control board 400 and the outdoor unit control board 200. The indoor unit control board 400 can be connected to the ground wire connection position on the first terminal block 210 through the online line 300. In this way, the indoor unit control board 400 does not need to be separately set up and then set up a ground wire for grounding. When the online line 300 and the first terminal block 210 are connected, the ground wire 500 and the online line 300 are respectively electrically connected to the ground wire connection position, so that the indoor unit control board 400 and the outdoor unit control board 200 can be grounded only through one ground wire 500 to achieve a common ground. The grounding connection method of the indoor unit control board 400 and the outdoor unit control board 200 is simpler, which is conducive to simplifying the grounding connection steps of the indoor unit control board 400 and the outdoor unit control board 200, and can reduce the number of grounding wire harnesses of the air conditioner, further improving the wiring and assembly efficiency of the entire machine, and facilitating maintenance and assembly.

[0089] In this way, according to the embodiment of the present invention, the air conditioner can simplify the structure of the outdoor control panel 200, and further simplify the connection between the outdoor control panel 200 and the indoor control panel 400. After the outdoor control panel 200 and the indoor control panel 400 are connected, they only need to be grounded through a grounding wire 500, and the grounding connection method is more convenient and simple.

[0090] Other structures and operations of the air conditioner according to the embodiment of the present invention are well known to those skilled in the art and will not be described in detail here.

[0091] The air conditioner in the present invention performs a refrigeration cycle of the air conditioner by using a compressor, a condenser, an expansion valve and an evaporator. 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.

[0092] The compressor compresses high-temperature, high-pressure refrigerant gas and discharges the compressed gas. The discharged refrigerant gas flows into the condenser. The condenser condenses the compressed refrigerant into a liquid phase, releasing heat into the surrounding environment through the condensation process.

[0093] The expansion valve expands the high-temperature, high-pressure liquid refrigerant condensed in the condenser to a lower-pressure liquid. The evaporator evaporates the refrigerant expanded in the expansion valve and returns the low-temperature, low-pressure refrigerant gas to the compressor. The evaporator achieves cooling by utilizing the latent heat of evaporation to exchange heat with the material being cooled. Throughout this cycle, the air conditioner regulates the temperature and humidity of the indoor space.
