[0002] With the development of society and the continuous improvement of people's living standards, various air conditioning devices have become one of the indispensable electrical equipment in people's daily lives. Various air conditioning devices can help people reach a temperature and humidity that they can adapt to when the ambient temperature and humidity are too high or too low. Current air conditioning devices mainly include various types of air conditioners and fans.

[0003] When the current air conditioner is running in dehumidification mode, if the user switches the air speed of the air conditioner, the wind speed of the indoor fan changes rapidly and drastically, which often causes the indoor evaporator temperature to change sharply, causing the outlet air temperature to fluctuate directly. The frequency change of the compressor is adjusted according to the temperature change of the indoor evaporator, which makes the frequency change of the compressor relatively lagging. The outlet air temperature changes quickly while the compressor frequency adjustment is slow, resulting in large fluctuations in the outlet air temperature and dehumidification amount. In short, the current air conditioner has the problem of obvious fluctuations in the compressor frequency and outlet air temperature when adjusting the wind speed in the dehumidification mode, which cannot meet the requirements of constant temperature dehumidification, affecting the user experience and product performance. Summary of the invention

[0026] This embodiment first provides a dehumidification control method for an air conditioner, which can avoid large fluctuations in air outlet temperature and dehumidification amount when the air conditioner switches wind speed, meet the requirements of constant temperature dehumidification, and effectively improve the user experience and product performance. Figure 1 FIG. 1 is a schematic diagram of a dehumidification control method for an air conditioner according to an embodiment of the present invention. Figure 1 As shown, the dehumidification control method of the air conditioner may include the following steps:

[0027] Step S102, when the air conditioner is running in the dehumidification mode, receiving a trigger signal for switching the air speed of the air conditioner;

[0028] Step S104, obtaining the current wind speed of the air conditioner and the set wind speed after switching;

[0029] Step S106, determining the working state of the indoor fan of the air conditioner according to the current wind speed and the set wind speed;

[0030] Step S108, controlling the indoor fan to operate according to the determined working state.

[0031] In the above steps, step S102 receives a trigger signal for switching the wind speed of the air conditioner when the air conditioner is running in the dehumidification mode, wherein the wind speed of the air conditioner may include: strong, high, medium, low, silent, etc. If the new set wind speed is different from the current wind speed, it can be considered that the trigger signal for the wind speed switching is received. For example, if the current wind speed is high and the new set wind speed is low, then the trigger signal for the wind speed switching can be received; or if the current wind speed is medium and the new set wind speed is strong, then the trigger signal for the wind speed switching can be received.

[0032] In a specific embodiment, step S102 of receiving a trigger signal for switching the air conditioner wind speed may specifically include: receiving a power-on signal sent by a display device, a voice device, a remote controller, or a mobile terminal bound to the air conditioner. The mobile terminal may be a mobile smart device, such as a smart phone, a tablet computer, etc.

[0033] Step S104 obtains the current wind speed of the air conditioner and the set wind speed after switching, wherein the current wind speed and the set wind speed after switching may include the above-mentioned: strong, high wind, medium wind, low wind, silent, etc. The order of the above wind speeds is arranged in a gradually decreasing order. If the wind speed is switched from the previous one to the later one, for example, from high wind to low wind, it means that the wind speed of the air conditioner is reduced; if the wind speed is switched from the later one to the previous one, for example, from medium wind to strong, it means that the wind speed of the air conditioner is increased.

[0034] Step S106 determines the working state of the indoor fan of the air conditioner according to the current wind speed and the set wind speed. Specifically, it can be determined whether the wind speed of the indoor fan of the air conditioner is gradually reduced or gradually increased according to the current wind speed and the set wind speed. The key point is that the wind speed of the indoor fan in this embodiment changes slowly and gradually, rather than changing rapidly and significantly like the indoor fan of the air conditioner in the prior art. The dehumidification control method of the air conditioner in this embodiment slowly and gradually adjusts the wind speed of the indoor fan, which can not only make the final wind speed meet the user's set wind speed requirements, but also avoid large fluctuations in the outlet air temperature and dehumidification amount, and meet the requirements of constant temperature dehumidification.

[0035] In a specific embodiment, the indoor heat exchanger of the air conditioner is provided with an electronic expansion valve to divide the indoor heat exchanger into an evaporation section and a condensation section. When the air enters the air conditioner, it is at the inlet temperature. The evaporation section cools and dehumidifies a part of the air, and the condensation section heats up the other part of the air, so that the outlet temperature after the cooled part of the air and the heated part of the air are mixed is close to the inlet temperature, thereby realizing constant temperature dehumidification.

[0036] For example, if the inlet temperature of the air entering the air conditioner is 10°C, a part of the air is cooled to 8°C through the evaporation section, and the other part of the air is heated to 12°C through the condensation section, then the two parts of air can be mixed to maintain the outlet temperature at 10°C, which is close to the inlet temperature. In other words, the air conditioner of this embodiment can make the inlet temperature of the air entering the air conditioner and the outlet temperature of the air flowing out of the air conditioner similar through the unique setting of the indoor heat exchanger, thereby achieving constant temperature. Especially when the air conditioner is running in the dehumidification mode, constant temperature dehumidification can be effectively achieved.

[0037] Because the air conditioner of this embodiment needs to achieve the effect of constant temperature dehumidification, when the air conditioner is running in the dehumidification mode, it is more necessary to strictly ensure the stability of the outlet air temperature to avoid large fluctuations in the outlet air temperature. The dehumidification control method of the air conditioner of this embodiment can slowly and gradually adjust the wind speed of the indoor fan when the air conditioner switches the wind speed, thereby avoiding large fluctuations in the outlet air temperature and dehumidification amount, and meeting the requirements of constant temperature dehumidification.

[0038] After determining the working state of the indoor fan of the air conditioner according to the current wind speed and the set wind speed in step S106, step S108 may be executed to control the indoor fan to operate according to the determined working state. Specifically, the working state of the indoor fan of the air conditioner determined according to the current wind speed and the set wind speed may be: gradually decreasing according to a preset speed, or gradually increasing according to the preset speed.

[0039] Then, when it is determined that the wind speed of the indoor fan is gradually decreasing according to the preset speed, the wind speed of the indoor fan can be controlled to gradually decrease according to the preset speed. When it is determined that the wind speed of the indoor fan is gradually increasing according to the preset speed, the indoor fan can be controlled to gradually increase according to the preset speed. In this way, the working state of the indoor fan can be made to conform to the current actual situation, so that the final wind speed can meet the requirements of the wind speed set by the user, and large fluctuations in the outlet air temperature and dehumidification amount can be avoided, thereby meeting the requirements of constant temperature dehumidification.

[0040] In a preferred embodiment, after controlling the indoor fan to operate according to the determined working state in step S108, the following may also be included: controlling the compressor of the air conditioner to change synchronously according to the working state determined by the indoor fan. Specifically, when the wind speed of the indoor fan is controlled to gradually decrease according to the preset speed, the compressor of the air conditioner can be controlled to synchronously reduce the operating frequency; when the wind speed of the indoor fan is controlled to gradually increase according to the preset speed, the compressor can be controlled to synchronously increase the operating frequency. This can effectively solve the problem of delayed adjustment of the compressor operating frequency, further ensure the stability of the outlet air temperature, and enhance the user experience.

[0041] In summary, the dehumidification control method of the air conditioner in this embodiment receives a trigger signal for switching the wind speed of the air conditioner when the air conditioner is operating in a dehumidification mode, obtains the current wind speed of the air conditioner and the set wind speed after switching, determines the working state of the indoor fan of the air conditioner according to the current wind speed and the set wind speed, and controls the indoor fan to operate according to the determined working state. This can avoid large fluctuations in the air outlet temperature and dehumidification amount when the air conditioner switches the wind speed, meet the requirements of constant temperature dehumidification, and effectively improve the user experience and product performance.

[0042] In some optional embodiments, the air conditioner can achieve higher technical effects by further optimizing and configuring the above steps. The dehumidification control method of the air conditioner of this embodiment is described in detail below in combination with the introduction of an optional execution process of this embodiment. This embodiment is only an example of the execution process. During the specific implementation, the execution order and operating conditions of some steps can be modified according to the specific implementation requirements. Figure 2Detailed flow chart of a dehumidification control method for an air conditioner according to an embodiment of the present invention, the dehumidification control method for an air conditioner comprises the following steps:

[0043] Step S202, when the air conditioner is running in the dehumidification mode, receiving a trigger signal for switching the air speed of the air conditioner;

[0044] Step S204, obtaining the current wind speed of the air conditioner and the set wind speed after switching;

[0045] Step S206, determining whether the set wind speed is less than the current wind speed, if so, executing step S208, if not, executing step S214;

[0046] Step S208, determining that the wind speed of the indoor fan is gradually reduced according to a preset speed;

[0047] Step S210, controlling the wind speed of the indoor fan to gradually decrease according to a preset speed;

[0048] Step S212, controlling the compressor of the air conditioner to synchronously reduce the operating frequency;

[0049] Step S214, setting the wind speed to be greater than the current wind speed;

[0050] Step S216, determining that the wind speed of the indoor fan gradually increases according to a preset speed;

[0051] Step S218, controlling the wind speed of the indoor fan to gradually increase according to a preset speed;

[0052] Step S220, controlling the compressor of the air conditioner to synchronously increase the operating frequency.

[0053] In the above steps, firstly, step S202 and step S204 are executed, and when the air conditioner is running in the dehumidification mode, a trigger signal for the air conditioner wind speed switching is received; and the current wind speed of the air conditioner and the set wind speed after switching are obtained. The wind speed of the air conditioner may include: strong, high wind, medium wind, low wind, silent, etc. If the new set wind speed is different from the current wind speed, it can be considered that the trigger signal for the wind speed switching is received. For example, if the current wind speed is high wind and the new set wind speed is low wind, then the trigger signal for the wind speed switching can be received; or if the current wind speed is medium wind and the new set wind speed is strong, then the trigger signal for the wind speed switching can be received.

[0054] In a specific embodiment, step S202 of receiving a trigger signal for switching the air conditioner wind speed may specifically include: receiving a power-on signal sent by a display device, a voice device, a remote controller, or a mobile terminal bound to the air conditioner. The mobile terminal may be a mobile smart device, such as a smart phone, a tablet computer, etc.

[0055] Step S204 obtains the current wind speed of the air conditioner and the set wind speed after switching, wherein the current wind speed and the set wind speed after switching may include the above-mentioned: strong, high wind, medium wind, low wind, silent, etc. The order of the above wind speeds is arranged in a gradually decreasing order. If the wind speed is switched from the previous one to the later one, for example, from high wind to low wind, it means that the wind speed of the air conditioner is reduced; if the wind speed is switched from the later one to the previous one, for example, from medium wind to strong, it means that the wind speed of the air conditioner is increased.

[0056] That is to say, when the air conditioner is operating in dehumidification mode, if a trigger signal for wind speed switching is received, the steps of this embodiment can be executed in sequence. If the air conditioner is not operating in dehumidification mode, or the wind speed is not switched in dehumidification mode, the air conditioner operation can be controlled normally.

[0057] Then step S206 can be executed to determine whether the set wind speed is less than the current wind speed. If the judgment result of step S206 is yes, that is, the set wind speed is less than the current wind speed, steps S208 and S210 are executed to determine that the wind speed of the indoor fan gradually decreases according to the preset speed, and control the wind speed of the indoor fan to gradually decrease according to the preset speed.

[0058] If the set wind speed is less than the current wind speed, it means that the wind speed of the air conditioner is reduced. For example, if the current wind speed is strong, the wind speed is set to medium. At this time, the wind speed of the indoor fan can be controlled to gradually decrease according to the preset speed. The wind speed of the indoor fan is a gradual and slow decrease process, which can increase the temperature change time of the evaporation section of the indoor heat exchanger and slow down the temperature change rate of the evaporation section. In a specific embodiment, the preset speed can be 100r / 20s, that is, the wind speed of the indoor fan is reduced by 100r every 20s. It should be noted that the specific values ​​of the above-mentioned preset speeds are only for example, and are not limitations of the present invention. In some other embodiments, it can be set to other values ​​according to actual conditions.

[0059] Furthermore, after the wind speed of the indoor fan is controlled to gradually decrease according to the preset speed in step S210, step S212 can be executed to control the compressor of the air conditioner to synchronously reduce the operating frequency. For example, while the indoor fan is reduced by 100r every 20s, the compressor can also be controlled to reduce the operating frequency every 20s, that is, the compressor also slowly and gradually reduces its operating frequency. And it should be emphasized that the operating frequency of the compressor can be reduced immediately after the indoor fan reduces the wind speed, and the adjustment of the two is almost synchronized.

[0060] If the judgment result of step S206 is no, step S214 is executed to set the wind speed greater than the current wind speed, and then steps S216 and S218 are executed to determine that the wind speed of the indoor fan gradually increases according to the preset speed, and the wind speed of the indoor fan is controlled to gradually increase according to the preset speed. Since step S202 receives the trigger signal of the air conditioner wind speed switching, that is, the wind speed of the air conditioner must be changed, and the set wind speed and the current wind speed must be different, then when the judgment result of step S206 to determine whether the set wind speed is less than the current wind speed is no, it can be accurately determined that the set wind speed is greater than the current wind speed.

[0061] If the set wind speed is greater than the current wind speed, it means that the wind speed of the air conditioner has increased. For example, if the current wind speed is low, the set wind speed is high. At this time, the wind speed of the indoor fan can be controlled to gradually increase according to the preset speed. The wind speed of the indoor fan is a gradual and slow increase process, which can increase the temperature change time of the evaporation section of the indoor heat exchanger and slow down the temperature change speed of the evaporation section.

[0062] Furthermore, after the wind speed of the indoor fan is gradually increased according to the preset speed in step S218, step S220 can be executed to control the compressor of the air conditioner to synchronously increase the operating frequency. For example, while the indoor fan increases by 100r every 20s, the compressor can also be controlled to increase its operating frequency every 20s, that is, the compressor also slowly and gradually increases its operating frequency. It should be emphasized that the operating frequency of the compressor can be increased immediately after the indoor fan increases its wind speed, and the regulation of the two is almost synchronized.

[0063] Figure 3 Schematic diagram of the change of the outlet air temperature and the compressor frequency caused by the change of the wind speed of the indoor fan in the dehumidification control method of the air conditioner in the prior art. Figure 3 As shown, according to the dehumidification control method of the air conditioner in the prior art, when the wind speed is switched and reduced, the rotation speed of the indoor fan will be greatly and quickly reduced, the evaporation temperature of the indoor evaporator will be reduced, the outlet air temperature will be reduced, and then the compressor will reduce the frequency, the evaporation temperature of the indoor evaporator will increase, the outlet air temperature will increase, and the compressor will increase the frequency, the outlet air temperature will decrease, and then the compressor will reduce the frequency again, the outlet air temperature will increase and then stabilize.

[0064] pass Figure 3It can be clearly seen that when the current air conditioner is running in dehumidification mode, if the user switches the air conditioner's wind speed, the indoor fan's wind speed changes rapidly and drastically, which often causes the indoor evaporator temperature to change sharply, causing the outlet air temperature to fluctuate directly. The frequency change of the compressor is adjusted according to the temperature change of the indoor evaporator, which makes the frequency change of the compressor relatively lagging, the outlet air temperature changes faster and the compressor frequency adjustment is slower, which will cause the outlet air temperature and dehumidification amount to fluctuate greatly. In short, the current air conditioner has the problem of obvious fluctuations in compressor frequency and outlet air temperature when adjusting the wind speed in dehumidification mode, which cannot meet the requirements of constant temperature dehumidification, affecting the user experience and product performance.

[0065] Figure 4 FIG. 1 is a schematic diagram of changes in outlet air temperature and compressor frequency caused by changes in the wind speed of an indoor fan in a dehumidification control method for an air conditioner according to an embodiment of the present invention. Figure 4 As shown, according to the dehumidification control method of the air conditioner of this embodiment, when the wind speed is switched and reduced, the speed of the indoor fan is first slightly reduced, the evaporation temperature of the evaporation section of the indoor heat exchanger is reduced, and the outlet air temperature is reduced. Then, the compressor reduces the frequency synchronously according to the reduction in the speed of the indoor fan, the evaporation temperature of the evaporation section of the indoor heat exchanger increases, and the outlet air temperature increases. At this time, the speed of the indoor fan is slightly reduced again, and then the compressor also reduces the operating frequency. The outlet air temperature slightly decreases and then increases, and the overall fluctuation is not large. Then, the speed of the indoor fan is slightly reduced again, and then the compressor also reduces the operating frequency. This process is repeated, and finally the wind speed of the indoor fan is reduced to the set wind speed. The outlet air temperature does not fluctuate much during the whole process, and the indoor temperature does not fluctuate much, so constant temperature dehumidification can be achieved.

[0066] pass Figure 4 It can be clearly seen that when the air conditioner of this embodiment is running in the dehumidification mode, if the user switches the wind speed of the air conditioner, the wind speed of the indoor fan can be adjusted slowly and gradually, thereby avoiding large fluctuations in the outlet air temperature and dehumidification amount, and meeting the requirements of constant temperature dehumidification. In addition, the operating frequency of the compressor can be adjusted synchronously according to the working state of the indoor fan, effectively solving the problem of lagging adjustment of the compressor operating frequency, further ensuring the stability of the outlet air temperature, and improving the user experience.

[0067] It should be noted that the reason why the outlet air temperature decreases after the speed of the indoor fan is that the cooling capacity is the product of the indoor unit air volume and the enthalpy difference, where the enthalpy difference is the difference between the inlet air enthalpy value and the outlet air enthalpy value. In the short time of switching the wind speed, the cooling capacity is constant. Since the wind speed is reduced, the indoor unit air volume is reduced, so it can be deduced that the enthalpy difference increases. Since the inlet air enthalpy value is also constant in a short time, it can be concluded that the outlet air enthalpy difference decreases, and the reduction of the outlet air enthalpy difference also means that the outlet air temperature decreases.

[0068] During the constant temperature dehumidification process, the evaporation section of the indoor heat exchanger will be controlled by the operating frequency of the compressor. For example, if the operating frequency of the compressor increases, the evaporation temperature of the evaporation section will decrease, and the air outlet temperature will decrease. At the same time, the air outlet temperature of the indoor unit of the air conditioner is also affected by the wind speed and air volume of the indoor fan. If the wind speed and air volume of the indoor fan suddenly decrease, for example, from strong to silent, the air outlet temperature of the indoor unit of the air conditioner will decrease. Therefore, in order to achieve constant temperature dehumidification, the indoor fan control must be combined with the control of the compressor operating frequency to ensure that the wind speed of the indoor fan does not change suddenly, so that the wind speed of the indoor fan can be slowly and gradually reduced or increased. At the same time, the operating frequency of the compressor changes synchronously to ensure that the overall air outlet temperature of the indoor unit of the air conditioner remains unchanged.

[0069] In summary, the dehumidification control method of the air conditioner in this embodiment, when the set wind speed is less than the current wind speed, controls the wind speed of the indoor fan to gradually decrease according to the preset speed, and controls the compressor of the air conditioner to synchronously reduce the operating frequency; when the set wind speed is greater than the current wind speed, controls the indoor fan to gradually increase according to the preset speed, and controls the compressor to synchronously increase the operating frequency, and synchronously adjusts the operating frequency of the compressor according to the working status of the indoor fan, effectively solving the problem of lagging adjustment of the compressor operating frequency, further ensuring the stability of the outlet air temperature, and improving the user experience.

[0070] This embodiment further provides an air conditioner, which may include a controller 300 . Figure 5 FIG. 3 is a schematic block diagram of a controller 300 of an air conditioner according to an embodiment of the present invention. Figure 5 As shown, the controller 300 may include: a processor 310 and a memory 320, wherein the memory 320 stores a machine executable program 321, and when the machine executable program 321 is executed by the processor 310, it is used to implement any of the above-mentioned dehumidification control methods for the air conditioner.

[0071] The processor 310 may be a central processing unit (CPU) or a digital processing unit, etc. The processor 310 sends and receives data through a communication interface. The memory 320 is used to store a machine executable program 321 executed by the processor 310. The memory 320 is any medium that can be used to carry or store a desired program code in the form of an instruction or data structure and can be accessed by a computer, and may also be a combination of multiple memories 320.

[0072] The machine executable program 321 can be downloaded from a computer-readable storage medium to a corresponding computing / processing device or downloaded via a network (e.g., the Internet, a local area network, a wide area network, and / or a wireless network) and installed in the controller 300. The controller 300 can be used to control the operation of the air conditioner itself, and also to receive signals from other devices and send signals to other devices, for example, it can send signals to a mobile terminal and receive signals sent by the mobile terminal.

[0073] It should be noted that the air conditioner in this article may specifically refer to an indoor unit of an air conditioner. The dehumidification control method of the air conditioner implemented by the air conditioner in this embodiment receives a trigger signal for switching the wind speed of the air conditioner when the air conditioner is operating in a dehumidification mode, obtains the current wind speed of the air conditioner and the set wind speed after switching, determines the working state of the indoor fan of the air conditioner according to the current wind speed and the set wind speed, controls the indoor fan to operate according to the determined working state, and can avoid large fluctuations in the air outlet temperature and dehumidification amount when the air conditioner switches the wind speed, meet the requirements of constant temperature dehumidification, and effectively improve the user experience and product performance.

[0074] In addition, the air conditioner in this embodiment implements the dehumidification control method of the air conditioner. When the set wind speed is less than the current wind speed, the wind speed of the indoor fan is controlled to gradually decrease according to the preset speed, and the compressor of the air conditioner is controlled to synchronously reduce the operating frequency; when the set wind speed is greater than the current wind speed, the indoor fan is controlled to gradually increase according to the preset speed, and the compressor is controlled to synchronously increase the operating frequency, and the operating frequency of the compressor is synchronously adjusted according to the working status of the indoor fan, which effectively solves the problem of lagging adjustment of the compressor operating frequency, further ensures the stability of the air outlet temperature, and improves the user experience.
