[0002] With the development of economy and technology, air conditioners are more and more widely used, and the functions of air conditioners are more and more diversified, and quick connection air conditioners have emerged as the times require. The quick connection air conditioner is generally installed by the user, and the user uses a quick connector assembly to assemble part of the pipeline in the air conditioner to form a refrigerant circulation system that meets the user's own use requirements. In the process of assembly, the quick connector assembly and the stop valve need to be installed in cooperation in the process of installing some pipelines, and after installation is completed, the user needs to manually open the stop valve to realize the normal operation of the refrigerant circulation system; when disassembling, the user needs to manually close the stop valve to smoothly disassemble the pipeline.

[0003] However, since the user is not a professional air conditioner installer and does not have the professional knowledge required for air conditioner installation, in the process of air conditioner installation and disassembly, the user's manual operation may fail to open or close the stop valve as required, so that the connected pipeline cannot be turned on or blocked as required. Among them, insufficient opening degree of the stop valve is easy to cause system blockage, which leads to damage of the compressor, so that the user cannot normally use the air conditioner, and the stop valve is not tightly closed, which is easy to cause the system pressure process to fail to disassemble the connected pipeline, which is not convenient for the user to operate. Therefore, the current quick connection air conditioner has the problem of poor user experience due to poor installation and disassembly effects. SUMMARY

[0046] The realization of the objective, functional features and advantages of the present invention will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0047] It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

[0048] The main solution of this invention is: an air conditioner based on a first and second pipeline detachably connected by a quick-connect assembly, wherein the quick-connect assembly is equipped with a solenoid valve to acquire control commands from the air conditioner; the control commands characterize the target state required by the air conditioner, the target state including whether the first pipeline and the second pipeline are connected or blocked; the solenoid valve is controlled to open or close according to the control commands so that the air conditioner reaches the target state.

[0049] Because current technology often involves non-professional air conditioning installers lacking the necessary expertise, manual operation during installation and disassembly can lead to issues such as shut-off valves failing to open or close properly. This can prevent the connected pipes from being properly connected or disconnected. Insufficient valve opening can cause system blockage, damaging the compressor and rendering the air conditioner unusable. Conversely, a loosely closed valve can prevent the system from disassembling the pipes, hindering user operation. Therefore, current quick-connect air conditioners suffer from poor installation and disassembly results in a subpar user experience.

[0050] The present invention provides the above-mentioned solution, which aims to improve the installation and disassembly of quick-connect air conditioners, thereby enhancing the user experience.

[0051] This invention provides a quick-connect assembly, specifically for the quick connection of pipes in an air conditioner.

[0052] In this embodiment, refer to Figure 1The quick-connect assembly includes a first quick-connect 1 and a second quick-connect 2 for detachable connection to the first quick-connect 1. At least one of the first quick-connect 1 and the second quick-connect 2 is provided with a solenoid valve 3, which is used to open or close according to the control command of the air conditioner to connect or block a first pipe 4 and a second pipe 5 in the air conditioner. The first pipe 4 is the pipe provided with the first quick-connect 1, and the second pipe 5 is the pipe provided with the second quick-connect 2.

[0053] This invention also proposes an air conditioner. In this embodiment, the air conditioner is a split-type air conditioner. In other embodiments, the air conditioner may also be a unitary air conditioner.

[0054] In this embodiment of the invention, reference is made to Figure 2 and Figure 3 The air conditioner includes a first pipe, a second pipe, a first quick connector 1 on the first pipe, a second quick connector 2 on the second pipe, and a control device 100. The first quick connector 1 and the second quick connector 2 are detachably connected. At least one of the first quick connector 1 and the second quick connector 2 is provided with a solenoid valve 3, which is connected to the control device 100. The control device 100 can be used to control the opening or closing of the solenoid valve 3.

[0055] In the refrigerant circulation loop of an air conditioner, there may be one or more sets of the first pipe and the second pipe equipped with corresponding quick connectors.

[0056] In this embodiment, the air conditioner has at least two first pipes and at least two second pipes. The at least two first pipes include a first inlet pipe 41 and a first outlet pipe 42 for the indoor unit 01 of the air conditioner. The at least two second pipes include a second inlet pipe 51 and a second outlet pipe 52 for the outdoor unit 02 of the air conditioner. A solenoid valve 3 installed on the quick-connect fitting connecting the first inlet pipe 41 and the second outlet pipe 52 is defined as a first solenoid valve 31, and a solenoid valve 3 installed on the quick-connect fitting connecting the first outlet pipe 42 and the second inlet pipe 51 is defined as a second solenoid valve 32. Both the first solenoid valve 31 and the second solenoid valve 32 are connected to a control device 100, which can control the opening or closing of the first solenoid valve 31 and the second solenoid valve 32.

[0057] The first inlet pipe 41 is the refrigerant passage from the outdoor unit 02 to the indoor unit 01, the first outlet pipe 42 is the refrigerant passage from the indoor unit 01 to the outdoor unit 02, the second inlet pipe 51 is the refrigerant passage from the indoor unit 01 to the outdoor unit 02, and the second outlet pipe is the refrigerant passage from the outdoor unit 02 to the indoor unit 01.

[0058] When the first solenoid valve 31 is open, the second outlet pipe 52 is connected to the first inlet pipe 41; when the second solenoid valve 32 is open, the first outlet pipe 42 is connected to the second inlet pipe 51. When the first solenoid valve 31 is closed, the second outlet pipe 52 is blocked from the first inlet pipe 41; when the second solenoid valve 32 is closed, the first outlet pipe 42 is blocked from the second inlet pipe 51.

[0059] When both the first solenoid valve 31 and the second solenoid valve 32 are open, the first inlet pipe 41 and the second outlet pipe 52 are connected, and the second inlet pipe 51 and the first outlet pipe 42 are connected to form a refrigerant circulation loop for the air conditioner. The refrigerant circulation loop includes a compressor 81, an outdoor heat exchanger 82, a throttling device 83, and an indoor heat exchanger 84 connected in sequence. When the air conditioner is running, the refrigerant flowing out of the compressor in the outdoor unit 02 flows into the indoor unit 01 through the second outlet pipe 52 and the first inlet pipe 41 in sequence. After heat exchange in the indoor heat exchanger 84 in the indoor unit 01, it flows back into the outdoor unit 02 through the first outlet pipe 42 and the second inlet pipe 51 in sequence, and then flows back to the compressor 81. When the air conditioner has a cooling and heating switching function, the refrigerant flow direction in the first inlet pipe 41 and the first outlet pipe 42 can be switched, and the refrigerant flow direction in the second inlet pipe 51 and the second outlet pipe 52 can be switched.

[0060] Furthermore, refer to Figure 3 The air conditioner also includes a first temperature sensor 6, which is located in the indoor heat exchanger 84 and can be used to detect the temperature of the indoor heat exchanger 84. The first temperature sensor 6 is connected to the control device 100, and the control device 100 can acquire the temperature value detected by the first temperature sensor 6.

[0061] Furthermore, refer to Figure 3 The air conditioner also includes a second temperature sensor 7, which is located at the return air vent of the indoor unit 01 or in the indoor environment outside the indoor unit 01. The second temperature sensor 7 can be used to detect the indoor ambient temperature. The second temperature sensor 7 is connected to the control device 100, and the control device 100 can acquire the temperature value detected by the second temperature sensor 7.

[0062] In this embodiment of the invention, reference is made to Figure 3 The control device 100 of the air conditioner includes a processor 1001 (e.g., CPU), a memory 1002, etc. The components in the control device 100 are connected via a communication bus. The memory 1002 can be a high-speed RAM or a stable, non-volatile memory, such as a disk drive. Optionally, the memory 1002 can also be a storage device independent of the aforementioned processor 1001.

[0063] Those skilled in the art will understand that Figure 3The device structure shown does not constitute a limitation on the device and may include more or fewer components than shown, or combine certain components, or have different component arrangements.

[0064] like Figure 3 As shown, the memory 1002, which is a computer-readable storage medium, may include a control program for an air conditioner. Figure 3 In the device shown, the processor 1001 can be used to call the control program of the air conditioner stored in the memory 1002 and execute the relevant steps of the control method of the air conditioner in the following embodiments.

[0065] This invention also provides a control method for an air conditioner, applied to the aforementioned air conditioner.

[0066] Reference Figure 4 This application proposes an embodiment of a control method for an air conditioner. In this embodiment, the control method for the air conditioner includes:

[0067] Step S10: Obtain the control command of the air conditioner; the control command represents the target state required by the air conditioner, and the target state includes the connection or blockage of the first pipeline and the second pipeline;

[0068] The control commands here can be commands entered by the user after completing the connection of the first and second pipelines, or commands generated by the detection module when it detects that the first and second pipelines are in a connected state.

[0069] The control command may include a first command or a second command, wherein the first command represents a target state of air conditioner demand where the second pipe is connected to the first pipe, and the second command represents a target state of air conditioner demand where the second pipe is disconnected from the first pipe. When the first pipe is connected to the second pipe, refrigerant flow between the second pipe and the first pipe is permitted; when the first pipe is disconnected from the second pipe, refrigerant flow between the second pipe and the first pipe is not permitted.

[0070] In this embodiment, the first instruction is the air conditioner's power-on instruction, and / or the second instruction is the air conditioner's disassembly instruction. The power-on instruction indicates that the air conditioner requires operation; in this case, the second pipe in the air conditioner needs to be connected to the first pipe to allow refrigerant circulation and ensure the air conditioner's normal operation. The disassembly instruction indicates that the user needs to disassemble the air conditioner; in this case, the second pipe needs to be disconnected from the first pipe to prevent refrigerant flow, thus avoiding excessive pressure in both the first and second pipes that would prevent the two quick-connect fittings from being disassembled.

[0071] In other embodiments, when there is more than one set of the first conduit and the second conduit connected thereto, the control command may also include a third command, the third command representing the target state required by the air conditioner as the first conduit and the second conduit connected thereto at the first target location being connected, and the first conduit and the second conduit connected thereto at the second target location being blocked.

[0072] Step S20: Control the solenoid valve to open or close according to the control command so that the air conditioner reaches the target state.

[0073] In this embodiment, when the control command is a first command, the solenoid valve is opened; when the control command is a second command, the solenoid valve is closed.

[0074] In other embodiments, when there is more than one solenoid valve, when the control command is the third command, a first target solenoid valve that needs to be closed and a second target solenoid valve that needs to be opened can be determined, and the first target solenoid valve can be controlled to close and the second target solenoid valve can be controlled to open.

[0075] This invention proposes a control method for an air conditioner, applicable to air conditioners that use quick-connect fittings to detachably connect a second pipe to a first pipe. The quick-connect fittings are equipped with a solenoid valve. This method controls the solenoid valve to open or close according to the air conditioner's control commands, ensuring that the first and second pipes in the air conditioner are precisely in the required open or closed state as indicated by the control commands. The solenoid valve can replace the original shut-off valve in the air conditioner. During air conditioner installation and disassembly, when it is necessary to open or close the pipes, users without professional installation knowledge do not need to manually operate the shut-off valve. Instead, it can be controlled by an electrical signal, ensuring that the first and second pipes in the air conditioner are in the required open or closed state for installation and disassembly. This effectively avoids compressor damage due to improper pipe connection and prevents pipes from being improperly cut off, ensuring normal user operation of the air conditioner. This improves the installation and disassembly efficiency of quick-connect air conditioners, thereby enhancing the user experience.

[0076] Furthermore, based on the above embodiments, another embodiment of the control method for the air conditioner of this application is proposed. In this embodiment, the air conditioner includes at least two first pipes and at least two second pipes. The at least two first pipes include a first inlet pipe and a first outlet pipe of the indoor unit of the air conditioner, and the at least two second pipes include a second inlet pipe and a second outlet pipe of the outdoor unit of the air conditioner. A solenoid valve installed on a quick-connect fitting for connecting the first inlet pipe and the second outlet pipe is defined as a first solenoid valve, and a solenoid valve installed on a quick-connect fitting for connecting the first outlet pipe and the second inlet pipe is defined as a second solenoid valve. It should be noted that both the first pipe and the second pipe are pipes without shut-off valves. (Refer to...) Figure 5 Step S20 includes:

[0077] Step S21: When the control command is the first command, control the first solenoid valve and the second solenoid valve to open;

[0078] Step S22: When the control command is the second command, control the first solenoid valve and the second solenoid valve to close.

[0079] When both the first and second solenoid valves are open, the first inlet pipe and the second outlet pipe are connected, and the first outlet pipe is connected to the second inlet pipe to form a refrigerant circulation loop, allowing the refrigerant to flow between the indoor unit and the outdoor unit; when both the first and second solenoid valves are closed, the first inlet pipe and the second outlet pipe are blocked, and the first outlet pipe is blocked from the second inlet pipe, preventing the refrigerant from flowing between the indoor unit and the outdoor unit.

[0080] Based on this, when the air conditioner detects the first command, it can control the first and second solenoid valves to open and complete the refrigerant circulation loop connection required for normal air conditioner operation; when the air conditioner detects the second command, it can cut off the refrigerant circulation loop through the first and second solenoid valves. Controlling multiple solenoid valves at different positions with a single command improves the convenience of air conditioner installation and disassembly, further enhancing the installation and disassembly effect of quick-connect air conditioners and improving the user experience.

[0081] Furthermore, based on the above embodiments, another embodiment of the control method for the air conditioner of this application is proposed. In this embodiment, the second instruction is an instruction received when the air conditioner is in the on state, referring to... Figure 6 Step S22 includes:

[0082] Step S221: When the control command is the second command, control the air conditioner to remain on and control the first solenoid valve to close.

[0083] In this embodiment, when the air conditioner is kept on: the compressor remains on, and the indoor fan can remain on and operate at a set speed. In this embodiment, when the air conditioner is kept on: the compressor remains on, and the indoor fan can also be turned off.

[0084] When the air conditioner is on and no second command is received, both the first and second solenoid valves are in the open state. When the first solenoid valve is closed, the second solenoid valve remains open.

[0085] When the compressor is running, the first solenoid valve closes to prevent refrigerant from flowing from the outdoor unit to the indoor unit, while the operation of the second solenoid valve is not adjusted to keep it open. Under the drive of the compressor, the refrigerant in the indoor unit continues to flow to the outdoor unit, thereby allowing the compressor to recover the refrigerant. During the refrigerant recovery process, the system pressure gradually decreases.

[0086] Step S222: Obtain the temperature characteristic value of the indoor heat exchanger of the air conditioner and the indoor ambient temperature of the environment where the air conditioner is located;

[0087] Temperature characteristic values ​​may include the coil temperature detected after the first solenoid valve is closed at a first preset time interval, the change value of the coil temperature within a certain period of time after the first solenoid valve is closed, and / or the rate of change of the coil temperature of the indoor heat exchanger after the first solenoid valve is closed, etc.

[0088] In this embodiment, the current first temperature of the indoor heat exchanger is acquired when the first solenoid valve is closed; the current second temperature of the indoor heat exchanger is acquired after a first preset time interval; the temperature difference between the second temperature and the first temperature is determined, and the temperature characteristic value includes the temperature difference value and the second temperature. In this embodiment, the temperature difference value is the calculated result obtained by subtracting the first temperature from the second temperature. In other embodiments, the temperature difference value can also be the absolute value of the difference between the second temperature and the first temperature difference. The first and second temperatures can be detected by a temperature sensor installed in the middle of the indoor heat exchanger coil. This improves the accuracy of characterizing whether the refrigerant recovery of the air conditioning system is complete.

[0089] The indoor ambient temperature can be detected in real time when the first solenoid valve is closed, or it can be detected after a set interval following the closure of the first solenoid valve. The specific indoor ambient temperature can be detected by a temperature sensor located at the return air vent of the indoor unit.

[0090] Step S223: When the indoor ambient temperature and the temperature characteristic value meet the set conditions for refrigerant recovery to be completed, control the second solenoid valve to close and control the air conditioner to shut down.

[0091] Specifically, when the indoor ambient temperature and temperature characteristic value meet the set conditions for refrigerant recovery to be completed, the second solenoid valve can be closed in real time and the air conditioner can be turned off; alternatively, the solenoid valve can be closed after a set time interval and the air conditioner can be turned off.

[0092] The specific conditions set here may include the quantity of indoor ambient temperature and temperature characteristic values ​​that need to be met when refrigerant recovery is completed, or the numerical ranges that each needs to reach.

[0093] In this embodiment, when the temperature difference is greater than a first preset threshold and the second temperature is greater than the indoor ambient temperature, it is determined that the indoor ambient temperature and the temperature characteristic value meet the preset conditions for refrigerant recovery completion. Based on this, accurate identification of refrigerant recovery completion in the air conditioner can be achieved.

[0094] In this embodiment, by means of the above method, when it is necessary to block the refrigerant flow between the indoor and outdoor units, the first solenoid valve is closed first to achieve refrigerant recovery, and the second solenoid valve is closed after the refrigerant recovery is completed. This effectively reduces the system pressure and prevents excessive pressure from preventing the user from disconnecting the two quick-connect fittings when disassembling the first and second pipes, further improving the convenience of disassembling the quick-connect air conditioner. The method of obtaining temperature characteristic values ​​and the method of determining whether the set conditions for refrigerant recovery are met by combining the indoor ambient temperature and temperature characteristic values ​​can accurately identify the state of refrigerant recovery completion of the air conditioner, further ensuring that the system pressure can be reduced to below the pressure threshold that facilitates user disassembly, further improving the convenience of disassembling the quick-connect air conditioner.

[0095] Furthermore, after step S222, following the step of obtaining the temperature characteristic value of the indoor heat exchanger of the air conditioner and the indoor ambient temperature of the environment where the air conditioner is located, the system further includes: when the indoor ambient temperature and the temperature characteristic value do not meet the set conditions, controlling the second solenoid valve to close after a second preset time interval. Closing the second solenoid valve after a second preset time interval when the indoor ambient temperature and the temperature characteristic value do not meet the set conditions ensures sufficient time for refrigerant recovery in the system, while preventing the system from operating in a blocked state for an extended period, which could cause excessively high compressor discharge pressure and damage to the system. This facilitates refrigerant recovery and disassembly while protecting the system.

[0096] Furthermore, to better understand the solutions of the embodiments of the present invention, the following description uses the air conditioner installation method and air conditioner disassembly method based on the above-described air conditioner as an example:

[0097] I. Installation Method:

[0098] 1. The user should connect the first quick connector and the second quick connector according to the instructions, connect the first pipe and the second pipe between the indoor unit and the outdoor unit, and connect the power cord.

[0099] 2. The user inputs "power on" via remote control (i.e., the first command mentioned above);

[0100] 3. Upon receiving the first instruction, the first and second solenoid valves open simultaneously, completing the connection of the entire air conditioning system.

[0101] 4. Normal operation according to user settings.

[0102] II. Control methods for disassembling the machine: such as Figure 3 As shown.

[0103] 1. Step 1: After turning on the air conditioner, the user can use the remote control to "disassemble the unit with one click" (i.e., the second command mentioned above);

[0104] 2. Step Two: Keep the indoor fan running at the set speed, close the first solenoid valve, and record the pipe temperature T20 of the indoor heat exchanger and the indoor ambient temperature T10.

[0105] 3. Step 3: After a time of m seconds (i.e., the first preset time mentioned above), detect the tube temperature T2m of the indoor heat exchanger;

[0106] 4. Step Four: Determine whether T2m-T20>1 and T2m>T10-1 (i.e., the above-mentioned set conditions) are met. If they are met, close the second solenoid valve, complete the refrigerant recovery, and turn off the air conditioner. If the conditions are not met, proceed to Step Five.

[0107] 5. Step five: After another n seconds (i.e., the second preset time mentioned above), close the second solenoid valve to complete refrigerant recovery and turn off the air conditioner;

[0108] After refrigerant recovery is complete and the air conditioner is turned off, the user can directly disconnect the quick connector to complete the pipe disconnection.

[0109] Where T2 is the indoor heat exchanger temperature, T1 is the indoor ambient temperature, m is the time parameter (recommended value is 30), and n is the time parameter (recommended value is 10).

[0110] Furthermore, this invention also proposes a computer-readable storage medium storing a control program for an air conditioner. When the control program is executed by a processor, it implements the relevant steps of any of the above-described air conditioner control methods.
