[0022] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the specific embodiments of the present invention and the corresponding drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments.

[0023] It should be noted that the terms "first", "second", etc. in the specification and claims of the present invention and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments of the present invention described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units that are clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0024] When the user adjusts the wind speed, if the adjustment span is relatively large, for example, directly from super strong to silent, since the outdoor compressor was previously running at high frequency, if the internal fan speed is directly reduced to silent as set, since the outdoor compressor was previously running at high frequency and the refrigerant is still flowing at high speed, the internal fan will be quickly reduced, which will cause the sound of liquid flow. Sometimes this sound will be very loud, which will greatly affect the user's experience of using the air conditioner.

[0025] The invention provides a control method for an air conditioner.

[0026] Figure 1 It is a method schematic diagram of an embodiment of the air conditioner control method provided by the present invention.

[0027] like Figure 1 As shown, according to an embodiment of the present invention, the air conditioner control method at least includes step S110, step S120 and step S130.

[0028] Step S110, when an adjustment instruction for the rotation speed of the internal fan is received, it is determined whether the adjusted target rotation speed of the internal fan set by the adjustment instruction is greater than the current rotation speed of the internal fan.

[0029] Specifically, when the air conditioner is turned on, the internal fan runs at a preset initial internal fan speed. At this time, since the air conditioner has just been turned on and the external compressor has not yet run, the internal fan can directly run at a frequency that does not require linkage with the external compressor. The preset initial internal fan speed can be set by the user, for example, the user uses a remote control or a mobile phone APP to turn on the air conditioner and set the internal fan speed.

[0030] When an adjustment instruction for the speed of the indoor fan is received, it is determined whether the adjusted target speed of the indoor fan set by the adjustment instruction is greater than the current speed of the indoor fan, that is, whether the compressor frequency needs to be adjusted according to whether the target speed of the indoor fan is greater than the current speed of the indoor fan; if the target speed of the indoor fan is greater than the current speed of the indoor fan, there is no need to adjust the compressor frequency; therefore, if the target speed of the indoor fan is greater than the current speed of the indoor fan, the indoor fan is directly adjusted from the current speed of the indoor fan to the target speed of the indoor fan. If the target speed of the indoor fan is less than the current speed of the indoor fan, the frequency of the compressor needs to be adjusted. If the adjusted target speed of the indoor fan is from low to high, it is conducive to increasing the pressure and will not cause the sound of the liquid flow of the refrigerant. Therefore, it is not necessary to link with the frequency of the outdoor compressor. If the adjusted target speed of the indoor fan is from high to low, it needs to be linked with the frequency of the outdoor compressor.

[0031] For example, if the internal fan speed set by the user is higher than the current internal fan speed, that is, the internal fan speed is from low to high, because increasing the speed of the internal fan is conducive to increasing the pressure and will not cause the liquid flow sound of the refrigerant, the internal fan can be directly adjusted to the target speed without being linked to the frequency of the outdoor unit.

[0032] Step S120: If the target speed of the internal fan is greater than the current speed of the internal fan, an adjustment time is determined according to a speed adjustment range from the current speed of the internal fan to the target speed of the internal fan.

[0033] Specifically, if the adjusted target speed of the indoor fan set by the adjustment instruction is greater than the current speed of the indoor fan, that is, the speed is from high to low and needs to be linked with the frequency of the outdoor compressor, then the adjustment time is determined based on the speed adjustment range from the current speed of the indoor fan to the target speed of the indoor fan.

[0034] In a specific implementation, the adjustment time corresponding to the speed adjustment range from the current speed of the internal fan to the target speed of the internal fan is determined according to the correspondence between the preset different speed adjustment ranges and the adjustment time. In a specific implementation, the determined adjustment time is the time when the noise generated when the current speed of the internal fan is adjusted to the target speed of the internal fan can be less than a preset noise threshold. The noise is, for example, the sound of liquid flow.

[0035] Specifically, the correspondence between different internal fan speed adjustment ranges and adjustment times can be set in advance through experiments. For example, by experimentally testing the liquid flow sound size with different adjustment times for different internal fan speed adjustment ranges, the adjustment time with acceptable noise (for example, less than a preset noise threshold) is obtained, and set as the adjustment time corresponding to different internal fan speed adjustment ranges. The adjustment time T of the internal fan speed is formulated based on the noise experience results of the laboratory. That is, based on the conclusion experience of the experimental data (for example, a smaller liquid flow sound, a smoothly decreasing internal fan speed), and based on the degree of noise acceptance, it is considered that the deceleration noise is acceptable, thereby obtaining this time T.

[0036] According to the speed adjustment range from the current speed of the internal fan to the target speed of the internal fan, the corresponding adjustment time is searched from the preset corresponding relationship to determine the adjustment time corresponding to the current speed adjustment range. For example, if the current speed of the internal fan is V1, and the target speed of the internal fan set by the adjustment instruction is V2, then according to the current speed adjustment range of the internal fan V1 to V2, the corresponding adjustment time T is determined, that is, the time T required for the speed of the internal fan to be adjusted from V1 to V2 is obtained.

[0037] Different internal fan speeds correspond to different compressor frequencies. After the internal fan speed is reset (for example, the user changes the internal fan wind speed), the wind speed decreases, which means that the required cooling capacity decreases and the compressor frequency also needs to be adjusted (reduced). According to the adjusted internal fan target speed set by the adjustment instruction, the compressor target frequency to which the corresponding compressor needs to be adjusted can be determined.

[0038] Step S130, within the adjustment time, gradually adjusting the internal fan speed from the current internal fan speed to the internal fan target speed.

[0039] In a specific embodiment, the speed adjustment rate of the internal fan is determined based on the adjustment time and the speed value required to adjust the internal fan from the current internal fan speed to the internal fan target speed; and the internal fan is gradually adjusted from the current internal fan speed to the internal fan target speed according to the determined speed adjustment rate.

[0040] For example, the current running speed of the internal fan is V1=1000 revolutions per minute (r / min), and the target speed set by the user is V2=800 revolutions per minute; before the user sets the wind speed, the frequency of the external unit is P1=50HZ, and the corresponding target frequency of the compressor after adjusting the speed of the internal fan is P2=35HZ. The determined adjustment time is 60 seconds, and the adjustment rate of the internal fan speed is: (1000-800) / 60≈3 revolutions per second. Therefore, according to the internal fan speed decrease rate of 3 revolutions per second, the internal fan speed is adjusted until the user-set target speed of 800 revolutions per minute is reached.

[0041] Through the above adjustment of the internal fan speed, the liquid flow sound of the compressor can be effectively reduced, which greatly improves the comfort of users using the air conditioner.

[0042] In order to clearly illustrate the technical solution of the present invention, the execution process of the air conditioner control method provided by the present invention is described below with reference to a specific embodiment.

[0043] Figure 2 FIG. 1 is a schematic diagram of a specific embodiment of the air conditioning control method provided by the present invention. Figure 2 As shown, the user uses the remote control or the APP installed on the mobile terminal to turn on the machine and set the wind speed of the internal fan. The internal fan directly runs according to the wind speed set by the user without the need to be linked to the frequency of the external compressor.

[0044] When the user changes the speed of the internal fan, if the speed of the internal fan set by the user is higher than the current speed of the internal fan, that is, the speed of the internal fan is from low to high, since the speed of the internal fan is increased, it is conducive to the increase of pressure and will not cause the sound of the refrigerant flow, so the internal fan is directly adjusted to the target speed of the internal fan changed by the user, without the need to be linked with the frequency of the external compressor. If the speed of the internal fan set by the user is lower than the current speed of the internal fan, for example, the wind gear is lowered, then it is necessary to adjust it in combination with the frequency of the external compressor.

[0045] The current running speed of the indoor fan is V1, and the indoor fan speed changed by the user is used as the target speed V2. The speed range that the indoor fan needs to adjust is V1-V2. P1 is the current operating frequency of the compressor. The compressor frequency corresponding to the indoor fan speed changed by the user is P2, which is the target frequency that needs to be reduced. P1-P2 is the range in which the frequency of the outdoor compressor needs to be adjusted. According to the required adjustment range V1-V2 of the indoor fan speed, the adjustment time T of the indoor fan speed adjustment is determined, and according to the correspondence between the preset indoor fan speed adjustment range and the adjustment time, the adjustment time corresponding to the current indoor fan speed adjustment range is obtained, that is, the time T required for the indoor fan to change from V2 to V1 is obtained.

[0046] According to the time T required for the internal fan to change from V2 to V1, the internal fan uniformly reduces the wind speed, and after a period of time T, it finally reduces to the user-set wind speed V2, that is, the internal fan uniformly speeds from V1 to the target speed V2, and the adjustment time is T.

[0047] The invention also provides a control device for an air conditioner.

[0048] Figure 3 FIG. 1 is a structural block diagram of an embodiment of the air conditioner control device provided by the present invention. Figure 3 As shown, the air conditioner control device 100 includes: a judgment unit 110 , a determination unit 120 and an adjustment unit 130 .

[0049] The judging unit 110 is used to judge whether the adjusted target speed of the indoor fan set by the adjustment instruction is greater than the current speed of the indoor fan when receiving the adjustment instruction of the speed of the indoor fan.

[0050] Specifically, when the air conditioner is turned on, the internal fan runs at a preset initial internal fan speed. At this time, since the air conditioner has just been turned on and the external compressor has not yet run, the internal fan can directly run at a frequency that does not require linkage with the external compressor. The preset initial internal fan speed can be set by the user, for example, the user uses a remote control or a mobile phone APP to turn on the air conditioner and set the internal fan speed.

[0051] When receiving an adjustment instruction for the speed of the indoor fan, the judgment unit 110 judges whether the adjusted target speed of the indoor fan set by the adjustment instruction is greater than the current speed of the indoor fan, that is, whether the compressor frequency needs to be adjusted according to whether the target speed of the indoor fan is greater than the current speed of the indoor fan; if the target speed of the indoor fan is greater than the current speed of the indoor fan, there is no need to adjust the compressor frequency; therefore, if the target speed of the indoor fan is greater than the current speed of the indoor fan, the indoor fan is directly adjusted from the current speed of the indoor fan to the target speed of the indoor fan. If the target speed of the indoor fan is less than the current speed of the indoor fan, the frequency of the compressor needs to be adjusted. If the adjusted target speed of the indoor fan is from low to high, it is conducive to increasing the pressure and will not cause the sound of the liquid flow of the refrigerant. Therefore, it is not necessary to link with the frequency of the outdoor compressor. If the adjusted target speed of the indoor fan is from high to low, it needs to be linked with the frequency of the outdoor compressor.

[0052] For example, if the internal fan speed set by the user is higher than the current internal fan speed, that is, the internal fan speed is from low to high, because increasing the speed of the internal fan is conducive to increasing the pressure and will not cause the liquid flow sound of the refrigerant, the internal fan can be directly adjusted to the target speed without being linked to the frequency of the outdoor unit.

[0053] The determination unit 120 is used to determine the adjustment time according to the speed adjustment range from the current internal fan speed to the internal fan target speed if the determination unit 110 determines that the internal fan target speed is greater than the current internal fan speed.

[0054] Specifically, if the adjusted target speed of the indoor fan set by the adjustment instruction is greater than the current speed of the indoor fan, that is, the speed is from high to low and needs to be linked with the frequency of the outdoor compressor, then the adjustment time is determined based on the speed adjustment range from the current speed of the indoor fan to the target speed of the indoor fan.

[0055] In a specific implementation, the adjustment time corresponding to the speed adjustment range from the current speed of the internal fan to the target speed of the internal fan is determined according to the correspondence between the preset different speed adjustment ranges and the adjustment time. In a specific implementation, the determined adjustment time is the time when the noise generated when the current speed of the internal fan is adjusted to the target speed of the internal fan can be less than a preset noise threshold. The noise is, for example, the sound of liquid flow.

[0056] Specifically, the correspondence between different internal fan speed adjustment ranges and adjustment times can be set in advance through experiments. For example, by experimentally testing the liquid flow sound size with different adjustment times for different internal fan speed adjustment ranges, the adjustment time with acceptable noise is obtained, and it is set as the adjustment time corresponding to the different internal fan speed adjustment ranges. The adjustment time T of the internal fan speed is formulated based on the noise experience results of the comprehensive laboratory. That is, according to the conclusion experience of the experimental data (for example, a smaller liquid flow sound, a gently decreasing internal fan speed), according to the acceptance of the noise, it is considered that the deceleration noise is acceptable, and thus this time T is obtained.

[0057] According to the speed adjustment range from the current speed of the internal fan to the target speed of the internal fan, the corresponding adjustment time is searched from the preset corresponding relationship to determine the adjustment time corresponding to the current speed adjustment range. For example, if the current speed of the internal fan is V1, and the target speed of the internal fan set by the adjustment instruction is V2, then according to the current speed adjustment range of the internal fan V1 to V2, the corresponding adjustment time T is determined, that is, the time T required for the speed of the internal fan to be adjusted from V1 to V2 is obtained.

[0058] Different internal fan speeds correspond to different compressor frequencies. After the internal fan speed is reset (for example, the user changes the internal fan wind speed), the wind speed decreases, which means that the required cooling capacity decreases and the compressor frequency also needs to be adjusted (reduced). According to the adjusted internal fan target speed set by the adjustment instruction, the compressor target frequency to which the corresponding compressor needs to be adjusted can be determined.

[0059] The adjustment unit 130 is used to gradually adjust the internal fan speed from the current internal fan speed to the internal fan target speed within the adjustment time.

[0060] In a specific embodiment, the speed adjustment rate of the internal fan is determined based on the adjustment time and the speed value required to adjust the internal fan from the current internal fan speed to the internal fan target speed; and the internal fan is gradually adjusted from the current internal fan speed to the internal fan target speed according to the determined speed adjustment rate.

[0061] For example, the current running speed of the internal fan is V1=1000 revolutions per minute (r / min), and the target speed set by the user is V2=800 revolutions per minute; before the user sets the wind speed, the frequency of the external unit is P1=50HZ, and the corresponding target frequency of the compressor after adjusting the speed of the internal fan is P2=35HZ. The determined adjustment time is 60 seconds, and the adjustment rate of the internal fan speed is: (1000-800) / 60≈3 revolutions per second. Therefore, according to the internal fan speed decrease rate of 3 revolutions per second, the internal fan speed is adjusted until the user-set target speed of 800 revolutions per minute is reached.

[0062] Through the above adjustment of the internal fan speed, the liquid flow sound of the compressor can be effectively reduced, which greatly improves the comfort of users using the air conditioner.

[0063] The present invention also provides a storage medium corresponding to the air conditioner control method, on which a computer program is stored, and when the program is executed by a processor, the steps of any of the above methods are implemented.

[0066] The present invention also provides a computer program product corresponding to the air conditioner control method, comprising a computer program, and when the computer program is executed by a processor, the steps of any of the aforementioned methods are implemented.

[0067] According to this, the solution provided by the present invention determines whether the speed adjustment time needs to be determined according to whether the adjusted speed becomes smaller, and determines the speed adjustment time according to the speed range of adjusting the internal fan from the current internal fan speed to the internal fan target speed, which can effectively reduce the liquid flow sound of the compressor and greatly improve the comfort of users using air conditioners.
