Description

Technical Field

[0001] This application relates to the technical field of air conditioning control, and more particularly to an air conditioner. Background Technology

[0002] The compressor is a crucial component of an air conditioner, typically located in the outdoor unit. It not only compresses the refrigerant from a low-pressure state to a high-pressure state but also drives the refrigerant to circulate within the air conditioner's refrigeration system.

[0003] Compressors typically include single-rotor compressors and twin-rotor compressors. Currently, single-rotor compressors are commonly used in some fixed-frequency air conditioners, while twin-rotor compressors are commonly used in some variable-frequency or high-end air conditioners.

[0004] Single-rotor compressors have poor stability during operation, especially during compressor start-up and shutdown when the rotational inertia is large. Rubber feet are usually used at the connection between the compressor and the outdoor unit casing to absorb shock. However, rubber is relatively soft, and due to the large instantaneous impact force during compressor start-up and shutdown, the rubber feet cannot effectively restrict the compressor's rotation. This often leads to excessive stress in the suction pipe connected to the compressor and the discharge pipe connected to the liquid receiver, which can easily cause pipe rupture and affect the normal operation of the air conditioner.

[0005] In view of the above, this application is hereby submitted. Summary of the Invention

[0006] In view of the shortcomings of the related technologies, this application provides an air conditioner that can prevent the exhaust pipe and intake pipe connected to the compressor from exceeding the stress limit when the compressor starts or stops.

[0007] This application provides an air conditioner, including:

[0008] chassis;

[0009] The compressor has a connecting part at its bottom, which is connected to the casing. The compressor has a start state and a stop state.

[0010] A clamping assembly is used to clamp the connection to press the compressor in place;

[0011] The clamping assembly includes:

[0012] Connector, which connects to the housing;

[0013] The pressure plate is movably connected to the connector. When the pressure plate moves in the first direction, it can press the compressor tightly. When the pressure plate moves in the second direction opposite to the first direction, it can release the constraint on the compressor.

[0014] This technical solution uses a pressure plate to constrain the compressor, thus fixing the compressor to the casing and preventing the compressor from rotating relative to the casing during startup or shutdown, which could cause excessive stress in the pipelines connected to the compressor.

[0015] In some embodiments, the clamping assembly further includes a drive motor and a screw, with a pressure plate connected to the fixed end of the drive motor, one end of the screw connected to the output shaft of the drive motor, and the other end of the screw connected to a connector, which is fixedly connected to the bottom plate of the housing.

[0016] In some embodiments, a controller is also included, which is configured to:

[0017] Upon receiving a compressor start command or stop command, the control plate moves in the first direction.

[0018] In some embodiments, the controller is further configured to:

[0019] Upon receiving a compressor start command, the compressor is kept in its current stopped state until the pressure plate movement time is not less than a first preset time, at which point the compressor is started.

[0020] When a compressor stop command is received, the compressor is kept running in its current start state until the movement time of the pressure plate is not less than a first preset time, at which point the compressor is stopped.

[0021] In some embodiments, a position sensor is also included for detecting the position of the pressure plate; the position sensor is connected to the controller; the controller is configured to:

[0022] When a compressor start command is received, the compressor is kept in its current stopped state until the position sensor detects that the pressure plate is in the target position, at which point the compressor is started.

[0023] When a compressor stop command is received, the compressor is kept running until the position sensor detects that the pressure plate is in the target position, at which point the compressor is stopped.

[0024] This technical solution determines whether the pressure plate is pressing the compressor based on whether the pressure plate has moved to the target position, thereby ensuring the pressing effect of the pressure plate on the compressor.

[0025] In some embodiments, a position sensor is also included for detecting the position of the pressure plate; the position sensor is connected to the controller; the controller is configured to:

[0026] When a compressor start command is received, the compressor is controlled to remain in its current stopped state until the position sensor detects that the pressure plate is in the target position and the movement time of the pressure plate is not less than a first preset time, at which point the compressor is controlled to start.

[0027] When a compressor stop command is received, the compressor is controlled to remain in its current running state until the position sensor detects that the pressure plate is in the target position and the movement time of the pressure plate is not less than a first preset time, at which point the compressor is controlled to stop running.

[0028] In some embodiments, the controller is configured to:

[0029] When the compressor runs at a preset frequency, or after the compressor has been running for a second preset time, the control plate moves in the second direction.

[0030] This technical solution releases the constraint on the compressor after the compressor has been running at a set frequency or after the compressor has been running for a second preset time.

[0031] In some embodiments, the controller is configured to:

[0032] After the compressor stops running, the control plate moves in the second direction.

[0033] In some embodiments, the movement of the pressure plate from its initial position to its target position includes multiple time steps, each time step having a corresponding preset distance; the air conditioner includes a displacement sensor for monitoring the actual movement distance of the pressure plate; the displacement sensor is connected to a controller; the controller is further configured to:

[0034] Calculate the difference between the actual distance the pressure plate moves in the current time step and the preset distance. If the difference is greater than 0, control the pressure plate to move less than the difference in the next time step; if the difference is less than 0, control the pressure plate to move more than the difference in the next time step; if the difference is equal to 0, control the pressure plate to move normally in the next time step.

[0035] This application discloses a control method for an air conditioner, the air conditioner comprising:

[0036] chassis;

[0037] The compressor has a connecting part at its bottom, which connects to the casing. The compressor has two states: start-up and stop operation.

[0038] A clamping assembly is used to clamp the connection to press the compressor in place;

[0039] The clamping assembly includes:

[0040] Connector, which connects to the housing;

[0041] The pressure plate is movably connected to the connector. When the pressure plate moves in the first direction, it can press the compressor tightly. When the pressure plate moves in the second direction opposite to the first direction, it can release the constraint on the compressor.

[0042] Control methods include:

[0043] Upon receiving a compressor start command or stop command, the control plate moves in the first direction.

[0044] This technical solution applies constraints to the compressor before it starts and before it stops running, fixing the compressor to the casing to prevent it from rotating relative to the casing during startup or shutdown, which could cause excessive stress in the pipelines connected to the compressor.

[0045] The aforementioned air conditioner applies constraints to the compressor before it starts and before it stops running, fixing the compressor to the casing to prevent the compressor from rotating relative to the casing during startup or shutdown, which could cause excessive stress in the pipes connected to the compressor.

[0073] To make the objectives and implementation methods of this application clearer, the exemplary implementation methods of this application will be clearly and completely described below with reference to the accompanying drawings of the exemplary embodiments of this application. Obviously, the exemplary embodiments described are only some embodiments of this application, and not all embodiments.

Unless otherwise stated, these terms should be understood in their ordinary and common meaning.

[0075] The terms "first," "second," "third," etc., used in the specification, claims, and accompanying drawings of this application are used to distinguish similar or related objects or entities, and do not necessarily imply a specific order or sequence, unless otherwise specified. It should be understood that such terms are interchangeable where appropriate.

[0076] The terms “include” and “have”, and any variations thereof, are intended to cover but not exclusively include, for example, a product or device that includes a range of components is not necessarily limited to all of the components that are clearly listed, but may include other components that are not clearly listed or that are inherent to such product or device.

[0077] The air conditioner provided in this application can have various implementation forms, such as wall-mounted, floor-standing, or ceiling-mounted units.

[0078] An air conditioner includes an indoor unit, which is usually located indoors.

[0079] An air conditioner includes an outdoor unit, which is usually located outdoors. The outdoor unit works in conjunction with the indoor unit to enable the air conditioner to perform its functions.

[0080] The indoor unit includes an indoor heat exchanger, which is used to exchange heat with indoor air, thereby heating or cooling the indoor environment.

[0081] The specific structure of the indoor unit is existing technology in this field and will not be described in detail here.

[0082] like Figure 1 and Figure 2As shown, the outdoor unit includes a housing 100, which forms the overall appearance of the outdoor unit. The top and bottom of the housing 100 are opposite ends, and the height of the housing 100 extends from the top to the bottom. The left and right sides of the housing 100 are opposite sides, and the length of the housing 100 extends from the left to the right. The front and rear sides of the housing 100 are opposite sides, and the thickness of the housing 100 extends from the front to the rear.

[0083] like Figure 2 As shown, the housing 100 includes an air outlet 102, which is located on the front side of the housing 100. Air inside the housing 100 is output to the outside through the air outlet 102.

[0084] like Figure 1 As shown, the housing 100 includes an air inlet 101, which is located on the outer periphery of the housing 100. Air from outside the housing 100 enters the interior of the housing 100 through the air inlet 101.

[0085] In some embodiments, the air inlet 101 is located on the rear side of the housing 100.

[0086] In other embodiments, the air inlet 101 is located on the rear side of the housing 100 and on the left and / or right side of the housing 100 to increase the air intake of the outdoor unit.

[0087] In this embodiment, the air inlet 101 is located on the rear side and the right side of the housing 100.

[0088] like Figure 3 As shown, the housing 100 includes a base plate 110, which is located at the bottom of the housing 100. The outdoor heat exchanger 400 is placed on the base plate 110, and the compressor 500 is installed on the base plate 110.

[0089] like Figure 3 and Figure 5 As shown, the outdoor unit includes an outdoor heat exchanger 400, which is located inside the casing 100 and is positioned near the air inlet 101. The outdoor heat exchanger 400 is used to exchange heat with the air passing through it.

[0090] In some embodiments, the outdoor heat exchanger 400 extends from the left side of the housing 100, through the rear side of the housing 100, to the right side of the housing 100, so as to maximize the heat exchange area of ​​the outdoor heat exchanger 400 without changing the internal space of the housing 100.

[0091] like Figure 2As shown, the outdoor unit includes a fan 300, which is located inside the casing 100. The fan 300 is located on the leeward side of the outdoor heat exchanger 400 and is positioned near the air outlet 102.

[0092] With the operation of the fan 300, external air enters the casing 100 through the air inlet 101, and after heat exchange by the outdoor heat exchanger 400, it is output to the outside of the casing 100 through the air outlet 102.

[0093] In this embodiment, the fan 300 is an axial flow fan.

[0094] like Figure 1 As shown, the outdoor unit includes a fan cover 200, which is located at the air inlet 101. On the one hand, it can protect the fan 300 and prevent debris from entering the casing 100 through the air inlet 101 and contacting the fan 300, thus affecting the normal operation of the fan 300. On the other hand, it can make the air drawn in by the fan 300 more concentrated, thereby increasing the speed and pressure of the air and ultimately increasing the air output of the fan. In other words, the fan cover 200 can focus the air blown out, improve the heat dissipation effect, and make the cooling and heating effect better.

[0095] like Figure 3 and Figure 5 As shown, the outdoor unit includes a compressor 500, an outdoor heat exchanger 400, and an indoor heat exchanger, which together form a refrigerant circulation loop. The compressor 500 is used to compress the refrigerant from a low-pressure state to a high-pressure state and drive the refrigerant to circulate in the refrigerant circulation loop so that the indoor heat exchanger can cool or heat the indoor air.

[0096] The compressor 500 includes an air inlet, which is connected to a suction pipe 610. The end of the suction pipe 610 away from the compressor 500 is connected to the evaporator.

[0097] The compressor 500 includes an exhaust port, which is connected to an exhaust pipe 510. The end of the exhaust pipe 510 away from the compressor 500 is connected to the condenser.

[0098] When the air conditioner cools the indoor environment, the outdoor heat exchanger 400 acts as a condenser, and the indoor heat exchanger acts as an evaporator. The refrigerant is compressed by the compressor 500 and flows into the outdoor heat exchanger 400 to release heat, then flows into the indoor heat exchanger to absorb heat, and finally flows back into the compressor 500.

[0099] When the air conditioner heats the indoor environment, the outdoor heat exchanger 400 acts as an evaporator, and the indoor heat exchanger acts as a condenser. The refrigerant is compressed by the compressor 500 and flows into the indoor heat exchanger to release heat, then flows into the outdoor heat exchanger 400 to absorb heat, and finally flows back into the compressor 500.

[0100] like Figure 4 As shown, the compressor 500 has a connecting part 520 at the bottom, which is connected to the base plate 110 to install and fix the compressor 500.

[0101] The connecting part 520 is connected to the base plate 110 via a buffer member 800, which is used to absorb and buffer the vibration generated by the compressor 500. The buffer member 800 includes, but is not limited to, rubber pads.

[0102] Multiple buffers 800 are typically provided, and the multiple buffers 800 are distributed circumferentially on the connecting part 520 to increase the buffering effect of the buffers 800 on the vibration generated by the compressor 500.

[0103] like Figure 5 As shown, the outdoor unit includes a liquid receiver 600, which is located in the refrigerant circulation loop and is connected to the exhaust pipe 510.

[0104] When the operating state of compressor 500 changes, compressor 500 is prone to rotate relative to casing 100, which drives the suction pipe 610 and exhaust pipe 510 connected to compressor 500 to move, which can easily lead to an increase in the pipe pressure of suction pipe 610 and exhaust pipe 510 connected to compressor 500.

[0105] In this application, by setting up a clamping assembly 700, the clamping assembly 700 applies a constraint to the compressor 500 when the operating state of the compressor 500 changes, so as to prevent the compressor 500 from rotating relative to the casing 100, thereby preventing the pipeline pressure of the suction pipeline 610 and the exhaust pipeline 510 connected to the compressor 500 from exceeding the standard.

[0106] like Figure 6 and Figure 7 As shown, the clamping assembly 700 includes a pressure plate 720, which applies a constraint force to the compressor 500 to prevent the compressor 500 from rotating relative to the housing 100. When the pressure plate 720 moves in a first direction, it can clamp the compressor 500; when the pressure plate 720 moves in a second direction, it can release the constraint on the compressor 500, wherein the second direction is opposite to the first direction.

[0107] The clamping assembly 700 includes a drive motor 710, which drives the pressure plate 720 to move so that the pressure plate 720 clamps the compressor 500 or releases the pressure plate 720 from the compressor 500.

[0108] The drive motor 710 includes an output shaft, which is positioned downwards.

[0109] The drive motor 710 includes a fixed end, an output shaft rotatably connected to the fixed end, and a pressure plate 720 connected to the fixed end.

[0110] The clamping assembly 700 includes a screw 730, which is arranged along the height direction of the housing 100, and the upper end of the screw 730 is connected to the output shaft of the drive motor 710.

[0111] The clamping assembly 700 includes a connector 740 connected to the base plate 110. The connector 740 defines a connecting cavity, which is arranged along the height direction of the housing 100. The cavity wall of the connecting cavity is threaded. A screw 730 is disposed in the connecting cavity. The thread of the screw 730 meshes with the thread of the cavity wall of the connecting cavity so that the screw 730 and the connector 740 are connected to each other. The screw 730 can undergo linear helical motion with the connector 740.

[0112] The clamping assembly 700 includes a base 750 for fixing the connector 740; the base 750 is fixed to the base plate 110, and the connector 740 is located on the top of the base 750.

[0113] The working principle of the clamping assembly 700 is as follows: the drive motor 710 drives the screw 730 to rotate, and the screw 730 rotates linearly and helically relative to the connecting piece 740. Since the connecting piece 740 is fixedly connected to the base plate 110 through the base 750, the screw 730 moves up and down along the height direction of the housing 100, thereby driving the drive motor 710 and the pressure plate 720 installed at the fixed end of the drive motor 710 to move up and down, thereby causing the pressure plate 720 to press the compressor 500 or release the compressor 500.

[0114] In some embodiments of this application, the air conditioner includes a constraint member for constraining the compressor 500 so that the compressor 500 is fixedly connected to the base plate 110.

[0115] The air conditioner includes a drive motor 710, which is used to drive the constraint member to apply or release the constraint member on the compressor 500.

[0116] It should be noted that the components that constrain the compressor 500 and fix the compressor 500 to the base plate 110 include, but are not limited to, the clamping component 700.

[0117] In this application, the air conditioner is a fixed-frequency air conditioner. During the stable operation of the air conditioner, the compressor 500 operates at a set frequency, and the operating state of the compressor 500 usually does not change. During the start-up and stop-operation of the compressor 500, the operating frequency of the compressor 500 changes, causing the state of the compressor 500 to change. Therefore, in this application, the compressor 500 is constrained before it starts up and before it stops operating to prevent the compressor 500 from rotating relative to the casing 100.

[0118] It should be noted that when the pressure plate 720 presses against the compressor 500, the compressor 500 can be considered to be rigidly connected to the casing 100. At this time, the vibration generated by the compressor 500 will be transmitted to the casing 100. Therefore, if the pressure plate 720 keeps the compressor 500 pressed against it throughout the air conditioner's operation from start to stop, the buffer 800 cannot effectively buffer the vibration generated by the compressor 500. Therefore, in this application, the pressure plate 720 presses against the compressor 500 before it starts and before it stops running. When the compressor 500 is running stably at a set frequency, the pressure plate 720 releases the compressor 500, so that the buffer 800 can absorb and buffer the vibration generated by the compressor 500.

[0119] The air conditioner includes a controller, which is connected to the compressor 500 and is used to control the operation of the compressor 500.

[0120] The controller is connected to the drive motor 710 and is used to control the operation of the drive motor 710. The controller is configured to: control the drive motor 710 to drive the pressure plate 720 to press the compressor 500; control the drive motor 710 to drive the pressure plate 720 to release the pressure plate 720 from the compressor 500; press the pressure plate 720 to the compressor 500 before the compressor 500 starts and / or before the compressor 500 stops running; and release the pressure plate 720 from the compressor 500 when the compressor 500 is running at a set frequency.

[0121] The controller is also used to receive start-up and shutdown commands from the air conditioner so that it can control the compressor 500 and drive motor 710 to operate.

[0122] The controller is configured to: upon receiving the air conditioner start command, control the drive motor 710 to drive the pressure plate 720 to press the compressor 500; after the pressure plate 720 presses the compressor 500, control the compressor 500 to start.

[0123] The controller is configured to control the drive motor 710 to drive the pressure plate 720 to release the constraint on the compressor 500 when the compressor 500 is running at a set frequency.

[0124] The controller is configured to: upon receiving a shutdown command from the air conditioner, control the drive motor 710 to drive the pressure plate 720 to press the compressor 500; after the pressure plate 720 presses the compressor 500, control the compressor 500 to stop running.

[0125] It should be noted that the way the controller receives the air conditioner's start and stop commands, as well as the way the user transmits the air conditioner's start and stop commands to the controller, are conventional technical means in this field and will not be elaborated here.

[0126] To ensure the effective clamping of the compressor 500 by the pressure plate 720, the compressor 500 is started or stopped only after the pressure plate 720 has clamped the compressor 500. This prevents the compressor 500 from rotating relative to the casing 100 during startup or shutdown, which could cause excessive stress in the pipelines connected to the compressor 500.

[0127] like Figure 8 As shown, the controller is configured to: after receiving the air conditioner start command, control the drive motor 710 to drive the pressure plate 720 to press the compressor 500; if the pressure plate 720 presses the compressor 500, then control the compressor 500 to start; if the pressure plate 720 does not press the compressor 500, then control the drive motor 710 to drive the pressure plate 720 to continue pressing the compressor 500.

[0128] The controller is further configured to: when the compressor 500 operates at a set frequency, or after the compressor 500 has been running for a second preset time, control the drive motor 710 to drive the pressure plate 720 to release the constraint on the compressor 500; when the compressor 500 is not running at a set frequency after starting, control the drive motor 710 to drive the pressure plate 720 to continue pressing the compressor 500.

[0129] The controller is further configured to: upon receiving a shutdown command from the air conditioner, control the drive motor 710 to drive the pressure plate 720 to press the compressor 500; if the pressure plate 720 presses the compressor 500, control the compressor 500 to stop running; if the pressure plate 720 does not press the compressor 500, control the drive motor 710 to drive the pressure plate 720 to continue pressing the compressor 500; after the compressor 500 stops running, control the drive motor 710 to drive the pressure plate 720 to release the compressor 500.

[0130] In some embodiments of this application, the pressure plate 720 is used to determine whether it presses the compressor 500 tightly, so as to ensure the pressing effect of the pressure plate 720 on the compressor 500, thereby preventing the compressor 500 from rotating relative to the housing 100 during startup or shutdown, which would cause the stress in the pipeline connected to the compressor 500 to exceed the standard.

[0131] like Figure 9 As shown, the controller is further configured to: after receiving the air conditioner start-up command, record the time when the controller receives the start-up command, and control the drive motor 710 to drive the pressure plate 720 to move; when the air conditioner start-up time (i.e., the movement time of the pressure plate 720) is greater than or equal to a preset time, control the compressor 500 to start; when the movement time of the pressure plate 720 is less than the preset time, control the compressor 500 not to start until the movement time of the pressure plate 720 is greater than or equal to the preset time, then control the compressor 500 to start.

[0132] like Figure 10As shown, the controller is further configured to: after receiving the air conditioner shutdown command, control the drive motor 710 to drive the pressure plate 720 to move; when the movement time of the pressure plate 720 is greater than or equal to a preset time, control the compressor 500 to stop running; when the movement time of the pressure plate 720 is less than the preset time, control the compressor 500 to continue running until the movement time of the pressure plate 720 is greater than or equal to the preset time, and then control the compressor 500 to stop running.

[0133] It should be noted that the preset time is stored in the controller beforehand.

[0134] In this embodiment, after the controller receives the start-up command or shutdown command of the air conditioner, the control of the drive motor 710 to drive the pressure plate 720 to press the compressor 500 is considered as the start of the air conditioner's response. The time required for the drive motor 710 to drive the pressure plate 720 to start moving until the pressure plate 720 presses the compressor 500 is the response time of the air conditioner.

[0135] The controller is configured to, after receiving the start-up or shutdown command from the air conditioner, control the compressor 500 to start or stop operation only after a preset time.

[0136] That is, the controller is configured to: if the response time of receiving the air conditioner start command is greater than or equal to a preset time, then control the compressor 500 to start; if the response time of the controller receiving the air conditioner start command is less than the preset time, then control the compressor 500 not to start, until the response time of the controller receiving the air conditioner start command exceeds the preset time, then control the compressor 500 to start.

[0137] The controller is further configured to: if the response time of receiving the air conditioner shutdown command is greater than or equal to a preset time, then control the compressor 500 to stop running; if the response time of the controller receiving the air conditioner shutdown command is less than the preset time, then control the compressor 500 to continue running until the response time of the controller receiving the air conditioner shutdown command exceeds the preset time, then control the compressor 500 to stop running.

[0138] It should be noted that if the air conditioner's response time is less than the preset time, the pressure plate 720 may not have moved into place yet. The pressure plate 720 exerts less pressure on the compressor 500, resulting in a weaker fixing effect between the compressor 500 and the base plate 110. Therefore, after the air conditioner's response time is greater than or equal to the preset time, it is determined that the pressure plate 720 has moved into place, indicating that the pressure plate 720 has a better pressing effect on the compressor 500. This prevents the compressor 500 from rotating relative to the casing 100 during startup or shutdown, which could lead to excessive stress in the pipes connected to the compressor 500.

[0139] In some other embodiments of this application, the position of the pressure plate 720 determines whether the pressure plate 720 is pressing the compressor 500, so as to ensure the pressing effect of the pressure plate 720 on the compressor 500, thereby preventing the compressor 500 from rotating relative to the housing 100 during startup or shutdown, which would cause the stress in the pipeline connected to the compressor 500 to exceed the standard.

[0140] The air conditioner includes a position sensor, which is used to detect the position of the pressure plate 720. The position sensor is connected to the controller, which is used to acquire the detection information from the position sensor.

[0141] Specifically, such as Figure 11 As shown, the controller is further configured to: after receiving the air conditioner start command, control the drive motor 710 to drive the pressure plate 720 to move; when the pressure plate 720 moves to the target position, control the compressor 500 to start; when the pressure plate 720 has not moved to the target position, control the compressor 500 not to start, and control the drive motor 710 to continue driving the pressure plate 720 to move until the pressure plate 720 moves to the target position.

[0142] like Figure 12 As shown, the controller is further configured to: after receiving the air conditioner shutdown command, control the drive motor 710 to drive the pressure plate 720 to move; when the pressure plate 720 moves to the target position, control the compressor 500 to stop running; when the pressure plate 720 has not moved to the target position, control the compressor 500 to continue running and control the drive motor 710 to continue driving the pressure plate 720 to move until the pressure plate 720 moves to the target position.

[0143] In some other embodiments of this application, the position of the pressure plate 720 and the movement time of the pressure plate 720 satisfy any set condition, that is, it is determined that the pressure plate 720 presses the compressor 500.

[0144] In some embodiments, it is first determined whether the movement time of the pressure plate 720 exceeds a preset time. If the movement time of the pressure plate 720 is less than the preset time, it is then determined whether the pressure plate 720 has moved to the target position.

[0145] Specifically, such as Figure 13 As shown, the controller is further configured to: upon receiving the air conditioner's start-up command, control the drive motor 710 to drive the pressure plate 720 to move; when the movement time of the pressure plate 720 is greater than or equal to a preset time, control the compressor 500 to start; when the movement time of the pressure plate 720 is less than the preset time, further determine the position of the pressure plate 720; when the pressure plate 720 moves to the target position, control the compressor 500 to start; when the pressure plate 720 does not move to the target position, control the compressor 500 not to start until the movement time of the pressure plate 720 exceeds the preset time or the pressure plate 720 moves to the target position, then control the compressor 500 to start.

[0146] like Figure 14 As shown, the controller is further configured to: upon receiving a shutdown command from the air conditioner, control the drive motor 710 to drive the pressure plate 720 to move; when the movement time of the pressure plate 720 is greater than or equal to a preset time, control the compressor 500 to stop running; when the movement time of the pressure plate 720 is less than the preset time, further determine the position of the pressure plate 720; when the pressure plate 720 moves to the target position, control the compressor 500 to stop running; when the pressure plate 720 does not move to the target position, control the compressor 500 to continue running until the movement time of the pressure plate 720 exceeds the preset time or the pressure plate 720 moves to the target position, then control the compressor 500 to stop running.

[0147] In other embodiments, it is first determined whether the pressure plate 720 has moved to the target position. If the pressure plate 720 has not moved to the target position, it is then determined whether the movement time of the pressure plate 720 exceeds a preset time.

[0148] Specifically, such as Figure 15 As shown, the controller is further configured to: upon receiving the air conditioner's start-up command, control the drive motor 710 to drive the pressure plate 720 to move; when the pressure plate 720 moves to the target position, control the compressor 500 to start; when the pressure plate 720 has not moved to the target position, if the movement time of the pressure plate 720 is greater than or equal to a preset time, control the compressor 500 to start; if the movement time of the pressure plate 720 is less than the preset time, control the compressor 500 not to start until the movement time of the pressure plate 720 exceeds the preset time or the pressure plate 720 moves to the target position, then control the compressor 500 to start.

[0149] like Figure 16 As shown, the controller is further configured to: upon receiving a shutdown command from the air conditioner, control the drive motor 710 to drive the pressure plate 720 to move; when the pressure plate 720 moves to the target position, control the compressor 500 to stop running; when the pressure plate 720 has not moved to the target position, if the movement time of the pressure plate 720 is greater than or equal to a preset time, control the compressor 500 to stop running; if the movement time of the pressure plate 720 is less than the preset time, control the compressor 500 to continue running until the movement time of the pressure plate 720 exceeds the preset time or the pressure plate 720 moves to the target position, then control the compressor 500 to stop running.

[0150] In some other embodiments of this application, the pressure plate 720 is determined to press the compressor 500 only when both the position of the pressure plate 720 and the movement time of the pressure plate 720 meet the set conditions, so as to ensure the reliability of the pressure plate 720 pressing the compressor 500.

[0151] In some embodiments, the movement time of the pressure plate 720 is determined first, and then the position of the pressure plate 720 is determined.

[0152] like Figure 17 As shown, the controller is further configured to: after receiving the air conditioner start command, control the drive motor 710 to drive the pressure plate 720 to move; when the movement time of the pressure plate 720 is less than a preset time, control the compressor 500 not to start; when the movement time of the pressure plate 720 is greater than or equal to the preset time, further determine whether the pressure plate 720 has moved to the target position; if the pressure plate 720 has moved to the target position, control the compressor 500 to start; if the pressure plate 720 has not moved to the target position, control the compressor 500 not to start.

[0153] like Figure 18 As shown, the controller is further configured to: upon receiving a shutdown command from the air conditioner, control the drive motor 710 to drive the pressure plate 720 to move; when the movement time of the pressure plate 720 is less than a preset time, control the compressor 500 to continue running; when the movement time of the pressure plate 720 is greater than or equal to the preset time, further determine whether the pressure plate 720 has moved to the target position; if the pressure plate 720 has moved to the target position, control the compressor 500 to stop running; if the pressure plate 720 has not moved to the target position, control the compressor 500 to continue running.

[0154] In other embodiments, the position of the pressure plate 720 is determined first, and then the movement time of the pressure plate 720 is determined.

[0155] like Figure 19 As shown, the controller is further configured to: upon receiving the air conditioner start command, control the drive motor 710 to drive the pressure plate 720 to move; when the pressure plate 720 has not moved to the target position, control the compressor 500 not to start; when the pressure plate 720 moves to the target position, further determine whether the movement time of the pressure plate 720 is greater than or equal to a preset time; if the movement time of the pressure plate 720 is greater than or equal to the preset time, control the compressor 500 to start; if the movement time of the pressure plate 720 is less than the preset time, control the compressor 500 not to start.

[0156] like Figure 20 As shown, the controller is further configured to: upon receiving a shutdown command from the air conditioner, control the drive motor 710 to drive the pressure plate 720 to move; when the pressure plate 720 has not moved to the target position, control the compressor 500 to continue running; when the pressure plate 720 moves to the target position, further determine whether the movement time of the pressure plate 720 is greater than or equal to a preset time; if the movement time of the pressure plate 720 is greater than or equal to the preset time, control the compressor 500 to stop running; if the movement time of the pressure plate 720 is less than the preset time, control the compressor 500 to continue running.

[0157] In some embodiments of this application, the air conditioner includes a displacement sensor for detecting the moving distance of the pressure plate 720. The displacement sensor is connected to a controller, which acquires the detection information from the displacement sensor and determines the position of the pressure plate 720 based on the detection information.

[0158] It should be noted that the methods used to detect the position of the pressure plate 720 include, but are not limited to, using position sensors and displacement sensors. These are common knowledge in the field and will not be elaborated here.

[0159] In this application, the process of the pressure plate 720 moving from the initial position to the target position includes multiple time steps, and each time step has a corresponding preset distance; the controller is configured to: obtain the actual movement distance of the pressure plate 720 in the current time step, and if the actual movement distance of the pressure plate 720 in the current time step exceeds or is less than the corresponding preset distance, the excess or deficiency part is compensated in the next time step.

[0160] Specifically, such as Figure 21 As shown, the controller is further configured to: acquire and record the movement distance of the pressure plate in the current time step, calculate the difference between the actual movement distance of the pressure plate in the current time step and the preset distance as the difference value; if the difference value is greater than 0, control the pressure plate to move less than the difference value in the next time step; if the difference value is less than 0, control the pressure plate to move more than the difference value in the next time step; if the difference value is equal to 0, control the pressure plate to move normally in the next time step, and iterate in this way until the pressure plate 720 moves to the target position.

[0161] The following section uses the example of determining whether the pressure plate is pressing the compressor based on the movement time of the pressure plate to explain in detail the control principle of the air conditioner mentioned above.

[0162] The controller is configured to: upon receiving an air conditioner start-up command, record the time the controller receives the start-up command and control the drive motor 710 to drive the pressure plate 720 to move; obtain the actual movement distance of the pressure plate 720 within the current time step Δt; if the actual movement distance of the pressure plate 720 within the current time step Δt exceeds or falls short of the corresponding preset distance Δd, the excess or deficiency d is compensated in the next time step; if the actual movement distance of the pressure plate 720 within the current time step Δt is equal to the corresponding preset distance Δd, control the pressure plate 720 to continue moving Δd in the next time step; iterate through the time steps until the movement distance of the pressure plate 720 reaches the total preset distance d1; when the air conditioner start-up time t1 (i.e., the time after the controller receives the air conditioner start-up command, i.e., the movement time of the pressure plate 720) is greater than or equal to the preset time t, control the compressor 500 to start; when the movement time t1 of the pressure plate 720 is less than the preset time t, control the compressor 500 not to start until the time t after the controller receives the air conditioner start-up command. When the time exceeds the preset time t, the compressor will be started again at 500.

[0163] The controller is further configured to: after the compressor 500 starts, within a certain period of time, control the drive motor 710 to drive the pressure plate 720 to reset, releasing the constraint on the compressor 500; obtain the actual movement distance of the pressure plate 720 in the current time step Δt; if the actual movement distance of the pressure plate 720 in the current time step Δt exceeds or is less than the corresponding preset distance Δd, then the excess or deficiency d is compensated in the next time step; if the actual movement distance of the pressure plate 720 in the current time step Δt is equal to the corresponding preset distance Δd, then control the pressure plate 720 to continue moving a distance Δd in the next time step; iterate the time steps until the movement distance of the pressure plate 720 reaches the total preset distance d1.

[0164] The controller is further configured to: upon receiving a shutdown command from the air conditioner, record the time when the controller receives the shutdown command, and control the drive motor 710 to drive the pressure plate 720 to move; obtain the actual movement distance of the pressure plate 720 within the current time step Δt; if the actual movement distance of the pressure plate 720 within the current time step Δt exceeds or falls short of the corresponding preset distance Δd1, the excess or deficiency d1 is compensated in the next time step; if the actual movement distance of the pressure plate 720 within the current time step Δt is equal to the corresponding preset distance Δd1, control the pressure plate 720 to continue moving Δd1 in the next time step; iterate through the time steps until the movement distance of the pressure plate 720 reaches the total preset distance d2; when the shutdown time t2 of the air conditioner (i.e., the movement time of the pressure plate 720) is greater than or equal to the preset time t, control the compressor 500 to stop running; when the movement of the pressure plate 720... When the running time t2 is less than the preset time t, the compressor 500 continues to run until the air conditioner's shutdown time t2 is greater than the preset time t, at which point the compressor 500 stops running. After the compressor 500 has stopped running for a period of time, the drive motor 710 is controlled to drive the pressure plate 720 to reset, causing the pressure plate 720 to release the compressor 500. The actual movement distance of the pressure plate 720 within the current time step Δt is obtained. If the actual movement distance of the pressure plate 720 within the current time step Δt exceeds or falls short of the corresponding preset distance Δd1, the excess or deficiency d1 is compensated in the next time step. If the actual movement distance of the pressure plate 720 within the current time step Δt is equal to the corresponding preset distance Δd1, the pressure plate 720 continues to move Δd1 in the next time step. The time steps are iterated until the movement distance of the pressure plate 720 reaches the total preset distance d2.

[0165] The aforementioned air conditioner applies constraints to the compressor 500 before it starts and before it stops running, fixing the compressor 500 to the base plate 110 to prevent the compressor 500 from rotating relative to the casing 100 during startup or shutdown, which could cause excessive stress in the pipes connected to the compressor 500. After the compressor 500 runs at a set frequency, the constraints on the compressor 500 are released, allowing the buffer 800 to absorb and buffer the vibrations generated by the compressor 500, reducing the impact of the vibrations generated by the compressor 500 on the outdoor unit.

[0166] The above-mentioned air conditioner can avoid excessive stress in the exhaust pipe 510 and intake pipe 610 connected to the compressor 500 caused by the relative rotation between the compressor 500 and the casing 100, and can also effectively buffer the vibration generated during normal operation of the compressor 500.
