[0051] The present application provides an air conditioner, which comprises a gas-liquid separator 100. As shown in the figure, the gas-liquid separator 100 comprises a tank body 110, which is provided with a liquid inlet pipe 101 and a gas outlet pipe 102. In the working condition of the gas-liquid separator 100, liquid flows into the tank body 110 from the liquid inlet pipe 101, and after gas-liquid separation, gas flows out of the tank body 110 from the gas outlet pipe 102. Figure 1

[0052] In the first embodiment, the gas-liquid separator 100 comprises a tank body 110 and a heating device. As shown in the figure, the tank body 110 is provided with a mounting port 120, and the mounting port 120 is provided with a first connecting piece 130. As shown in the figure, the heating device comprises a heating piece 200 and a second connecting piece 230 connected with each other. The heating piece 200 extends into the tank body 110 through the mounting port 120, and the second connecting piece 230 is connected with the first connecting piece 130, so as to mount the heating device on the tank body 110, as shown in the figure. Figure 1 Figure 2 Figure 3

[0053] In the present embodiment, the heating device is detachably arranged. When mounting, first, the heating piece 200 extends into the tank body 110 through the mounting port 120, so as to heat the refrigerant in the tank body 110. Then, the second connecting piece 230 is fixedly connected with the first connecting piece 130, so as to mount the heating device on the tank body 110. When dismounting, first, the connection relationship between the second connecting piece 230 and the first connecting piece 130 is released, and then the heating piece 200 is pulled out from the mounting port 120, so as to dismount the heating device from the tank body 110. In this way, if the heating piece 200 is damaged or fails, it can be conveniently dismounted and replaced, and the utilization rate of the gas-liquid separator 100 is improved.

[0054] Optionally, as shown in the figure, the first connecting piece 130 is located outside the tank body 110, and the first connecting piece 130 comprises a sleeve 131 and a first connecting structure 132. The first end of the sleeve 131 is connected with the mounting port 120, and the first connecting structure 132 is arranged at the second end of the sleeve 131. Figure 1

[0055] In the present embodiment, the first connecting piece 130 is arranged outside the tank body 110, which can avoid occupying the internal space of the tank body 110 and guarantee the liquid storage capacity of the tank body 110. By arranging the sleeve 131, it is beneficial to guide the heating piece 200 to extend into or pull out the mounting port 120. When mounting, first, the heating piece 200 extends into the sleeve 131, and then extends into the tank body 110 from the mounting port 120 along the sleeve 131.​​​​​

[0056] Optionally, as shown in Figure 1 The sleeve 131 is a straight pipe, and the axis of the sleeve 131 coincides with the axis of the mounting port 120. This can achieve better guiding effect, and make the movement of the heating element 200 in the sleeve 131 more smooth, so as to quickly extend into or pull out of the mounting port 120.

[0057] Optionally, the first end of the sleeve 131 is welded to the mounting port 120. In this way, when the heating device is impacted by external force, the sleeve 131 can achieve better supporting effect.

[0058] Optionally, as shown in Figure 2 The heating element 200 includes a heating section 210 and a non-heating section 220. The first end of the heating section 210 extends into the tank 110 through the sleeve 131. The first end of the non-heating section 220 is connected to the second end of the heating section 210 and located in the sleeve 131.

[0059] In this embodiment, the first end of the heating section 210 extends into the tank 110 through the sleeve 131, so that the refrigerant in the tank 110 can be heated. Since the heating section 210 is directly exposed to the refrigerant, the heat transfer efficiency can be improved, and the refrigerant can be quickly and uniformly heated. Moreover, the non-heating section 220 is located in the sleeve 131, and the sleeve 131 can play a role of isolation and protection.

[0060] Optionally, the heating element 200 is configured as a column, the heating section 210 is located at the first end, and the non-heating section 220 is located at the second end.

[0061] Optionally, the second connecting member 230 includes a second connecting structure. The first end of the second connecting structure is connected to the second end of the non-heating section 220 and can be connected with the first connecting structure 132.

[0062] In this embodiment, through the close cooperation of the first connecting structure 132 and the second connecting structure, the risk of refrigerant leakage from the sleeve 131 can be reduced, and the sealing performance can be ensured. Moreover, the use of standardized connecting structures can simplify the assembly and disassembly process, reduce the operation difficulty and disassembly time, and improve the work efficiency.

[0063] Optionally, the first connecting structure 132 and the second connecting structure are configured as a clamping structure that cooperates with each other.

[0064] In this embodiment, the first connecting structure 132 includes a clamping groove, and the second connecting structure includes a clasp. During installation, the heating element is first extended into the tank 110 through the mounting port 120, and then the clasp is clamped in the clamping groove. During disassembly, the clamping connection between the clasp and the clamping groove is first released, and then the heating element 200 is pulled out of the mounting port 120.

[0065] Optionally, the first connecting structure 132 and the second connecting structure are configured as a mating plug-in structure.

[0066] In the embodiment, the first connecting structure 132 comprises a slot, and the second connecting structure comprises a plug. During installation, the heating element 200 is first inserted into the tank 110 through the installation opening 120, and then the plug is plugged into the slot. During disassembly, the plug and the slot are first disengaged, and then the heating element 200 is pulled out of the installation opening 120.

[0067] Optionally, the first connecting structure 132 and the second connecting structure are configured as a mating threaded connection structure.

[0068] In the embodiment, the first connecting structure 132 comprises an internal threaded head, and the second connecting structure comprises an external threaded head. During installation, the heating element is first inserted into the tank 110 through the installation opening 120, and then the external threaded head is screwed onto the internal threaded head. During disassembly, the threaded connection between the external threaded head and the internal threaded head is first disengaged, and then the heating element 200 is pulled out of the installation opening 120.

[0069] Optionally, as shown in Figure 2 The heating device further comprises a wiring terminal 240. The wiring terminal 240 is arranged on the second connecting piece 230. Moreover, a first end of the wiring terminal 240 is connected to the heating element 200, and a second end thereof is used to connect a heating power source through a wire.

[0070] In the embodiment, when the heating power source is working, the heating element 200 is supplied with power through the wiring terminal 240, and at this time, the heating element 200 heats the refrigerant in the tank 110. During disassembly, after the connection relationship between the second connecting piece 230 and the first connecting piece 130 is disengaged, the heating element 200, the second connecting piece 230 and the wiring terminal 240 can be disassembled together, facilitating overall replacement.

[0071] Optionally, as shown in Figure 1 The installation opening 120 is arranged on a side wall of the tank 110. In this way, the heating device extends into the tank 110 through the side wall of the tank 110 through the installation opening 120.

[0072] Optionally, as shown in Figure 4 A plurality of installation openings 120 are arranged in sequence along the height direction of the tank 110, and each installation opening 120 is provided with one heating device.

[0073] In the embodiment, the heating device is arranged at different heights of the tank 110, so that the refrigerant at different heights can be heated. In this way, the refrigerant can be heated uniformly. When multiple heating devices are used to heat simultaneously, the heating speed of the refrigerant can be increased, and the heating efficiency can be improved. In addition, when a heating device fails, the other heating devices can still work, so that the heating process of the refrigerant in the tank 110 will not be interrupted. In this way, the safety and reliability of the system are improved.

[0074] Optionally, the mounting port 120 is arranged at the top of the tank 110. In this way, the heating device is inserted into or extracted from the tank 110 from the top.

[0075] Optionally, the mounting port 120 is arranged at the bottom of the tank 110. In this way, the heating device is inserted into or extracted from the tank 110 from the bottom.

[0076] In the second embodiment, the gas-liquid separator 100 includes a tank 110 and a heating device. The tank 110 is used to store the refrigerant. As shown in the figure, the heating device includes a heating element 200, and the heating element 200 includes multiple heating segments 210. The heating element 200 is located in the tank 110 or attached to the outside of the tank 110, and at least two heating segments 210 are located at different heights of the tank 110. In addition, the heating segments 210 at different heights can be independently operated to heat the refrigerant at the corresponding height. Figures 5 to 8

[0077] In the embodiment, the heating element 200 is designed to include multiple heating segments 210, which are located at different heights of the tank 110, and the heating segments 210 at different heights can be independently operated. In this way, the refrigerant at different heights can be heated respectively, so that the gas-liquid separation effect can be optimized. When the liquid level in the tank 110 changes, by operating only the heating segments 210 below the corresponding liquid level, the dry burning condition can be avoided, and the energy can be saved. For example, when the liquid level rises, the rising liquid can be heated in time by operating the heating segments 210 at the high position. When the liquid level falls, only the heating segments 210 at the low position are operated, so that the heating segments 210 at the high position can be prevented from dry burning. In addition, the condition of uneven heating of the local refrigerant can also be avoided. For example, when the refrigerant temperature at different heights in the tank 110 is uneven, the corresponding heating segments 210 at the lower temperature position are operated or the power is increased, and the corresponding heating segments 210 at the higher temperature position are stopped or the power is reduced.

[0078] Optionally, the heating device further includes a wiring terminal 240. The first end of the wiring terminal 240 is electrically connected to the heating element 200, and the second end is connected to the heating power supply through a wire, so as to supply power to the multiple heating segments 210. Here, the circuit layout of the multiple heating segments 210 is not limited in particular, as long as the independent on-off control can be realized. ​

[0079] Optionally, as shown in Figure 5 the heating element 200 is configured as a cylinder and located in the tank 110. In this embodiment, the plurality of heating sections 210 are arranged along the axial direction of the heating element 200, and the axial direction of the heating element 200 is not perpendicular to the height direction of the tank 110. Figure 5

[0080] In this embodiment, the plurality of heating sections 210 are located at different heights of the tank 110 when the axial direction of the heating element 200 is not perpendicular to the height direction of the tank 110. In this way, each heating section 210 can heat the refrigerant at the corresponding height when it is running.

[0081] Optionally, as shown in Figure 5 the heating element 200 includes three heating sections 210 connected along the axial direction in sequence, which are respectively referred to as the first heating section 211, the second heating section 212 and the third heating section 213. In addition, the first heating section 211, the second heating section 212 and the third heating section 213 correspond to the low liquid level, the middle liquid level and the high liquid level in the tank 110 respectively.

[0082] In this embodiment, it is assumed that the initial liquid level of the refrigerant in the gas-liquid separator 100 is the middle liquid level. At this time, only the first heating section 211 and the second heating section 212 are running. When the air conditioner switches to the first working condition, the liquid level in the tank 110 rises to the high liquid level. At this time, the third heating section 213 is controlled to run at the same time, so as to heat the rising refrigerant in time. When the air conditioner switches to the second working condition, the liquid level in the tank 110 drops to the low liquid level. At this time, only the first heating section 211 is controlled to run, so as to prevent the second heating section 212 and the third heating section 213 from dry burning.

[0083] Optionally, when the heating element 200 is configured as a cylinder, the heating element 200 extends into the tank 110 from the top of the tank 110.

[0084] Optionally, when the heating element 200 is configured as a cylinder, the heating element 200 extends into the tank 110 from the bottom of the tank 110.

[0085] Optionally, as shown in Figure 5 the axial direction of the heating element 200 is parallel to the height direction of the tank 110.

[0086] In this embodiment, since the tank 110 also has the liquid inlet pipe 101 and the gas outlet pipe 102, arranging the axial direction of the heating element 200 parallel to the height direction of the tank 110 can reduce the interference between the heating element 200 and the liquid inlet pipe 101 and the gas outlet pipe 102.

[0087] Optionally, as shown in Figure 6 ​As shown, the heating element 200 is configured as a U-shape and located in the tank body 110. A plurality of heating sections 210 are arranged along the extension direction of the U-shape. In this way, compared with the columnar heating element 200, the symmetrical design of the U-shape can arrange more heating sections 210.

[0088] Optionally, the symmetrical line of the U-shape of the heating element 200 is parallel to the height direction of the tank body 110.

[0089] In the embodiment, since the tank body 110 further has the liquid inlet pipe 101 and the gas outlet pipe 102, arranging the symmetrical line of the U-shape of the heating element 200 parallel to the height direction of the tank body 110 can reduce the interference between the heating element 200 and the liquid inlet pipe 101 and the gas outlet pipe 102.

[0090] Optionally, due to the symmetrical arrangement of the U-shape, in the case that the tank body 110 has a low liquid level, a middle liquid level and a high liquid level, the low liquid level corresponds to two first heating sections 211, the middle liquid level corresponds to two second heating sections 212, and the high liquid level corresponds to two third heating sections 213, as shown. Figure 6

[0091] Optionally, the opening of the U-shape of the heating element 200 faces the top of the tank body 110.

[0092] Optionally, the opening of the U-shape of the heating element 200 faces the bottom of the tank body 110.

[0093] Optionally, as shown, the heating element 200 is configured as a spiral shape and located in the tank body 110. A plurality of heating sections 210 are arranged along the spiral direction of the heating element 200, and the spiral axis of the heating element 200 is not perpendicular to the height direction of the tank body 110. In this way, compared with the columnar heating element 200, the design of the spiral shape can increase the length of each heating section 210.

[0094] Optionally, the spiral axis of the heating element 200 is parallel to the height direction of the tank body 110, and / or the spiral axis of the heating element 200 coincides with the axis of the tank body 110.

[0095] In the embodiment, the tank body 110 further has the liquid inlet pipe 101 and the gas outlet pipe 102, and the projections of the liquid inlet pipe 101 and the gas outlet pipe 102 on the bottom of the tank body 110 are located inside the spiral shape. In this way, the interference between the heating element 200 and the liquid inlet pipe 101 and the gas outlet pipe 102 can be reduced.

[0096] Optionally, each spiral turn is designed as a heating section 210. The spiral shape of the heating element 200 includes three spiral turns connected in sequence, and the three spiral turns correspond to the first heating section 211, the second heating section 212 and the third heating section 213, respectively, as shown. Figure 7 Optionally, each spiral turn is designed as a heating section 210. The spiral shape of the heating element 200 includes three spiral turns connected in sequence, and the three spiral turns correspond to the first heating section 211, the second heating section 212 and the third heating section 213, respectively, as shown.​​

[0097] Optionally, each two helical turns are designed as a heating section 210. If the helical shape of the heating element 200 comprises six helical turns connected in sequence (not shown in the figure), the first and second helical turns from bottom to top correspond to the first heating section 211, the third and fourth helical turns correspond to the second heating section 212, and the fifth and sixth helical turns correspond to the third heating section 213.

[0098] Optionally, as shown in Figure 8 , the heating element 200 is configured in a circular ring shape and is sleeved on the outer sidewall of the tank body 110. Among them, the plurality of heating sections 210 are arranged in sequence along the height direction of the tank body 110.

[0099] In this embodiment, the heating element 200 is arranged outside the tank body 110, and the heating element 200 heats the refrigerant inside through the sidewall of the tank body 110. Moreover, the plurality of heating sections 210 are arranged in sequence along the height direction of the tank body 110, which facilitates heating of the refrigerant at different heights.

[0100] Optionally, the heating element 200 comprises three heating sections 210, which are sleeved in sequence on the sidewall of the tank body 110 along the height direction of the tank body 110, and are sequentially referred to as the first heating section 211, the second heating section 212 and the third heating section 213 from bottom to top, as shown in Figure 8 .

[0101] Optionally, the heating device further comprises a temperature sensor 250 and a controller. Among them, the temperature sensor 250 is used to monitor the temperature of the refrigerant at different heights in the tank body 110. The controller is electrically connected to the temperature sensor 250 and all the heating sections 210, and is configured to operate the corresponding heating section 210 according to the temperature signal of the temperature sensor 250.

[0102] In this embodiment, the temperature sensor 250 is used to monitor the temperature of the refrigerant at different heights in the tank body 110 and transmit the temperature signal to the controller. Here, the position of the temperature sensor 250 is not specifically limited and can be arranged on the heating element 200 (as shown in Figure 5 , on the outer sidewall of the tank body 110 (as shown in Figure 6 , or on the inner sidewall of the tank body 110 (as shown in Figure 7 ). Then, the controller controls the working condition of the corresponding heating section 210 according to the temperature signal. For example, the temperature of the refrigerant at the lower part of the tank body 110 is higher, while the temperature of the refrigerant at the higher part is lower. At this time, the controller controls the corresponding heating section 210 at the lower part of the tank body 110 to stop or reduce the power, and controls the corresponding heating section 210 at the higher part of the tank body 110 to operate or increase the power. In this way, the temperature of the refrigerant in the tank body 110 can be quickly and uniformly.
