Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of air conditioner control, and specifically provides a control method for preventing cold wind when an air conditioner is started in heating mode and the air conditioner. BACKGROUND

[0002] When an air conditioner is operated in heating mode in winter, the cold wind blown out after the air conditioner is powered on for the first time or after defrosting ends reduces the thermal comfort of the user, because the temperature of the indoor unit coil is low. In order to avoid this problem, the existing air conditioner is provided with a cold wind prevention mode after being powered on for the first time or after defrosting ends.

[0003] The cold wind prevention mode of the existing air conditioner mainly avoids the above-mentioned situation through the following two methods: one method is to adjust the air outlet of the indoor unit air deflector to an upward position, so that the cold wind is blown out along the air outlet upward, avoiding the cold wind directly blowing to the user. Another method is to stop the fan of the air conditioner indoor unit when the temperature of the coil in the air conditioner indoor unit is lower than the set temperature, so that the air conditioner does not blow air outward. After the compressor works for 3-5 minutes, the temperature of the coil in the indoor unit rises to the set temperature, and then the fan of the indoor unit starts to work, so that the air conditioner blows warm air outward. However, the effect of the two methods is that the fan of the indoor unit does not blow warm air for 3-5 minutes after the air conditioner is powered on for the first time or after defrosting ends. When the user enters the room from the cold outdoor and starts the air conditioner in heating mode, the user cannot feel the warm air immediately, thereby causing poor user experience. SUMMARY

[0004] The present application aims to solve the above-mentioned technical problem, i.e., to solve the problem that the fan of the indoor unit does not blow warm air for the first few minutes when the existing air conditioner is started in heating mode and operates in the cold wind prevention mode.

[0005] In a first aspect, the present application provides a control method for preventing cold wind when an air conditioner is started in heating mode, wherein the air outlet of the indoor unit of the air conditioner is provided with a heating device, and the control method comprises the following steps: when the indoor unit of the air conditioner receives a heating signal, detecting the coil temperature T p of the indoor unit; determining whether the air conditioner operates in a cold wind prevention mode or in a heating mode based on the coil temperature T p ; and starting the heating device when it is determined that the air conditioner operates in the cold wind prevention mode.

[0006] Further, the step of determining whether the air conditioner operates in a cold wind prevention mode or in a heating mode based on the coil temperature T p comprises: comparing the coil temperature T p with a first set temperature; and determining that the air conditioner operates in the cold wind prevention mode when the coil temperature T pWhen the temperature is lower than the first set temperature, the air conditioner is set to operate in anti-cold air mode; and / or, when the coil temperature T p When the temperature is not lower than the first set temperature, the air conditioner is set to operate in heating mode.

[0007] Furthermore, the control method also includes: when it is determined that the air conditioner is operating in the anti-cold air mode and the heating device is activated, based on the coil temperature T... p The change in speed adjusts the fan speed of the indoor unit.

[0008] Furthermore, the condition based on the coil temperature T p The change in temperature of the coil, adjusting the fan speed of the indoor unit, includes: when the coil temperature T changes, adjusting the fan speed of the indoor unit. p When the first set temperature is reached, the indoor unit's fan operates at a first speed; and / or, when the first set temperature is less than or equal to the coil temperature T... p When the second set temperature is reached, the indoor unit's fan operates at the second speed; and / or, when the second set temperature is less than or equal to the coil temperature T... p When the third set temperature is reached, the indoor unit's fan is operated at a third speed; wherein the first speed is less than the second speed, and the second speed is less than the third speed.

[0009] Furthermore, the condition based on the coil temperature T p Adjusting the fan speed of the indoor unit according to the change in temperature T also includes: when the coil temperature T... p After the third set temperature is reached and maintained for a first preset time period, the heating device stops operating, and the air conditioner exits the anti-cold air mode and enters the heating mode.

[0010] Further, the first set temperature is 30-32°C; and / or, the second set temperature is 35-37°C; and / or, the third set temperature is 40-42°C.

[0011] Further, 450rpm ≤ the first speed < 590rpm; and / or, 590rpm ≤ the second speed < 730rpm; and / or, 730rpm ≤ the third speed ≤ 870rpm.

[0012] Furthermore, the length of the first preset time period is 30 to 60 seconds.

[0013] Furthermore, the heating device is an electric heating device.

[0014] In a second aspect, the present invention also provides an air conditioner, including a memory and a processor, wherein the memory stores a computer program, and when the computer program is executed by the processor, it implements the control method described above for preventing cold air from entering the air conditioner when it is turned on for heating.

[0015] When the above technical solution is adopted, the present invention enables the air conditioner compressor, indoor unit, and outdoor unit to start running when the indoor unit receives a heating signal, and to operate according to the coil temperature T of the indoor unit. p Determine the air conditioner's operating mode: either anti-cold air mode or heating mode. If it's determined to be in anti-cold air mode, the heating element is activated to heat the air blown from the indoor unit's vents. This ensures that when the air conditioner is turned on in heating mode, the user can immediately feel the heating effect. This overcomes the drawbacks of existing air conditioners that blow cold air in the first few minutes of heating mode, or where the indoor unit's fan doesn't operate for the first few minutes after startup, resulting in no airflow from the indoor unit. This improves user comfort. To further enhance user comfort, when the air conditioner is operating in anti-cold air mode with the heating element activated, as the indoor unit's coil temperature T... p The increase in airflow correspondingly increases the fan speed of the indoor unit, allowing users to gradually feel the air conditioner blowing hotter air with stronger force, further enhancing the user's comfort experience.

[0024] like Figure 1 and Figure 2 As shown, this embodiment of the invention provides a control method for preventing cold air from blowing out when an air conditioner is turned on for heating. A heating device, such as an electric heating device or a PTC heater, is installed at the air outlet of the indoor unit of the air conditioner. This heating device heats the air blown out from the air outlet of the indoor unit. The control method for preventing cold air from blowing out when the air conditioner is turned on for heating in this embodiment includes the following steps:

[0025] Step S1: When the indoor unit of the air conditioner receives a heating signal, detect the coil temperature T of the indoor unit. p .

[0026] When an air conditioner is turned on in heating mode, the compressor, outdoor unit, outdoor unit fan, indoor unit, and indoor unit fan all start running and receive heating signals. A temperature sensor can be used to detect the coil temperature T of the indoor unit. p .

[0027] Step S2: Based on the indoor unit's coil temperature T p Determine whether the air conditioner is operating in anti-cold air mode or heating mode;

[0028] Specifically, compare the coil temperature T of the indoor unit. p Based on the comparison with the first set temperature, it is determined whether the air conditioner should operate in anti-cold air mode or heating mode; that is, when the coil temperature T... p When the temperature is below the first set temperature, the air conditioner will operate in anti-cold air mode; when the coil temperature T... p When the temperature is not lower than the first set temperature, the air conditioner will operate in heating mode.

[0029] Step S3: When the air conditioner is determined to be operating in anti-cold air mode, the heating device is activated. After the heating device is activated, the air blown by the indoor unit's fan to the indoor unit's air outlet is heated by the heating device, thus making the temperature of the air blown out of the indoor unit's air outlet higher than the temperature of the air that has not been heated by the heating device. This allows the air conditioner to provide warm air from the moment it is turned on in heating mode.

[0030] Furthermore, to provide users with better comfort, when the air conditioner is determined to be operating in anti-cold air mode and the heating device is activated, the temperature T is based on the coil temperature. p Adjust the indoor unit's fan speed according to the changes.

[0031] When an air conditioner is turned on in heating mode, the temperature of the indoor unit's coil continuously rises under the action of the compressor, thus heating the air inside the indoor unit. To provide users with a better air conditioning heating experience, the indoor unit's coil temperature T... p When the temperature is relatively low, although the air blown out of the air conditioner's indoor unit is heated by the indoor unit's coils and heating element, the air temperature increase is not very significant, and the user feels that the air blown out by the air conditioner is not very hot. Therefore, in this situation, the indoor unit's fan speed is also controlled at a lower speed. As the compressor runs, the indoor unit's coil temperature T... p As the temperature rises, the air heated by the indoor unit's coils and heating device also becomes increasingly hot. Therefore, the indoor unit's fan speed is increased accordingly, allowing users to experience strong, hot air and quickly raising the room temperature. Specifically,

[0032] When the coil temperature T p When the first set temperature is reached, the indoor unit's fan will run at the first speed.

[0033] When the first set temperature is less than or equal to the coil temperature T p When the second set temperature is reached, the indoor unit's fan will run at the second speed.

[0034] When the second set temperature is less than or equal to the coil temperature T p When the third set temperature is reached, the indoor unit's fan will run at the third speed.

[0035] The first rotational speed is less than the second rotational speed, and the second rotational speed is less than the third rotational speed.

[0036] Preferably, the first set temperature is 30-32℃, the second set temperature is 35-37℃, and the third set temperature is 40-42℃. The ranges of the first, second, and third set temperatures can be set according to the season and geographical location, and the embodiments of the present invention do not specifically limit this.

[0037] Preferably, the first speed range can be set to 450–590 rpm, the second speed range to 590–730 rpm, and the third speed range to 730–870 rpm. Further, each speed range can be further divided into several levels as needed. For example, the first speed can be divided into 1-3 levels, with level 1 at 450 rpm, level 2 at 520 rpm, and level 3 at 590 rpm. The ranges of the first, second, and third speeds, as well as the method of leveling and the range of each level, can be set as needed; this embodiment of the invention does not specifically limit these settings.

[0038] When the coil temperature T p After setting the third temperature and maintaining it for a first preset time period, the heating device stops operating, and the air conditioner exits the anti-cold air mode and enters the heating mode. Preferably, the length of the first preset time period is 30 to 60 seconds.

[0039] When the coil temperature T p After setting the third temperature and maintaining it for the first preset time period, it indicates that heating the air inside the indoor unit solely through the coil is sufficient to achieve the heating effect required for the air conditioner to operate in heating mode. Therefore, it is no longer necessary for the heating device to simultaneously heat the air passing through the indoor unit's air outlet. Thus, the heating device is turned off, causing the air conditioner to exit anti-cold air mode and enter heating mode. At this time, the indoor unit's fan operates at the speed set for the air conditioner's heating mode.

[0040] In a specific embodiment, such as Figure 2 and Figure 3 As shown, the control method for preventing cold air from blowing when the air conditioner is turned on for heating includes the following steps:

[0041] Step S10: Turn on the air conditioner in heating mode.

[0042] After the air conditioner is turned on, the compressor, outdoor unit, outdoor unit fan, indoor unit, and indoor unit fan all start running and receive a heating signal. The compressor begins to heat the coils in the indoor unit. The indoor unit fan begins to blow air out of the air conditioner through the indoor unit's air outlet.

[0043] Step S20: Based on the indoor unit's coil temperature T p Determine if the air conditioner is operating in anti-cold air mode.

[0044] When the indoor unit of the air conditioner receives a heating signal, it will detect the coil temperature T of the indoor unit. p And the detected indoor unit coil temperature T p Compared to the first set temperature of 32℃, if the coil temperature T p If the temperature exceeds the first set temperature of 32°C, it is determined that the air conditioner is operating in heating mode, and the process proceeds to step S70. In this case, the heating device will not be turned on.

[0045] When the detected indoor unit coil temperature T p When the temperature is below the first set temperature of 32℃, the air conditioner is determined to be operating in anti-cold air mode. At this time, while the air conditioner's compressor, outdoor unit, outdoor unit fan, indoor unit, and indoor unit fan are all running, the heating device installed at the air outlet of the indoor unit is activated. This causes the air inside the indoor unit to be heated by the heating device as it is blown through the indoor unit's air outlet by the indoor unit fan before being blown outside. This heated air leaving the indoor unit makes the user feel that the air conditioner is blowing warm air. However, because the air conditioner has just started operating in heating mode, although the compressor is running, the coil temperature of the indoor unit has not yet increased significantly. At this time, the heating device is still primarily used to heat the air leaving the indoor unit.

[0046] Step S30: Coil temperature T p When the first set temperature (e.g., 32°C) is reached, the indoor unit's fan operates at the first speed.

[0047] When the indoor unit's coil temperature T pWhen the temperature is below the first set temperature of 32°C, the air blown out by the indoor unit's fan is mainly heated by the heating device. Although the air blown out by the air conditioner is heated, the heating device's effect on air temperature is not very high, and the user does not feel that the air blown out by the air conditioner is very hot. Therefore, in this case, the indoor unit's fan speed is also controlled at a lower speed, that is, the indoor unit's fan runs at the first speed; so that the air conditioner blows air to the user with a relatively small airflow intensity, which provides a sense of warmth. When a user enters the room from the cold outdoors (e.g., in winter) and turns on the air conditioner in heating mode, existing air conditioners either blow cold air for the first 3-5 minutes until the compressor heats the indoor unit's coil to a certain temperature before blowing warm air; or the indoor unit does not blow air out until the compressor heats the indoor unit's coil to a certain temperature before blowing warm air. Compared with the above two situations, the control method of this application allows the user to feel a gentle warm air blown out by the air conditioner after turning on the air conditioner in heating mode. Especially when the outdoor temperature is very low, even though the air blown out by the air conditioner is only heated by the heating device, the temperature difference between the air conditioner and the outdoor temperature is still very large. Therefore, the user's intuitive feeling is that the air conditioner blows hot air immediately after being turned on in heating mode, which greatly improves the user's comfort.

[0048] Step S40: When the first set temperature (e.g., 32°C) ≤ coil temperature T p When the second set temperature (e.g., 37°C) is reached, the indoor unit's fan operates at the second speed.

[0049] As the compressor runs, the indoor unit's coil temperature T p The temperature continues to rise. This makes the heating effect of the indoor unit's coils on the air inside the unit increasingly significant. After being heated by both the indoor unit's coils and the heating element, the air temperature is significantly higher than when heated by the heating element alone. Specifically, when the indoor unit's coil temperature T... p When the temperature is raised to between the first set temperature of 32℃ and the second set temperature of 37℃, the heating effect of the indoor unit's coil on the air improves. With the combined heating effect of the indoor unit's coil and the heating element, the temperature of the air blown out by the indoor unit's fan increases. At this point, the user gradually adapts to the indoor temperature and the gentle warm air previously blown by the air conditioner. As the temperature of the "hot air" further decreases, the indoor unit's fan speed correspondingly increases, operating at a second speed higher than the first, thereby increasing the airflow. This allows the user to experience higher temperatures and stronger hot air after adapting to the previous temperature and intensity of the air blown by the air conditioner, further enhancing user comfort.

[0050] Step S50: When the second set temperature (e.g., 37°C) ≤ coil temperature Tp When the third set temperature (e.g., 40°C) is reached, the indoor unit's fan will run at the third speed.

[0051] Furthermore, as the compressor operates, the coil temperature T of the indoor unit increases. p When the temperature is raised to between the second set temperature of 37℃ and the third set temperature of 40℃, the heating effect of the indoor unit's coil on the air is greatly improved. Correspondingly, the indoor unit's fan operates at a third speed, which is higher than the second speed, further increasing the air volume delivered by the air conditioner, allowing users to experience an improvement in the heating effect of the air conditioner.

[0052] Step S60: When the coil temperature T p After setting the third temperature and maintaining it for the first preset time period, the heating device will stop operating, and the air conditioner will exit the anti-cold air mode.

[0053] When the indoor unit's coil temperature T p The third set temperature (e.g., 40°C) is maintained for a first preset time period (e.g., 30 seconds). This indicates that heating the air inside the indoor unit solely through the coils is sufficient to achieve the heating effect required for the air conditioner to operate in heating mode. Therefore, it is no longer necessary for the heating device to simultaneously heat the air passing through the indoor unit's air outlet. Thus, the heating device is turned off, causing the air conditioner to exit anti-cold air mode.

[0054] Step S70: The air conditioner operates in heating mode. At this time, the indoor unit's fan operates at the speed set in the heating mode.

[0055] Figure 3 The figure shows the coil temperature T of the indoor unit of the air conditioner. p An example of the relationship curve between the indoor unit's fan speed and the indoor unit's fan speed.

[0056] The control method for preventing cold air during air conditioner heating startup provided in this embodiment of the invention starts the compressor, indoor unit, and outdoor unit of the air conditioner when the indoor unit receives the heating signal, and adjusts the operation according to the coil temperature T of the indoor unit. p Determine the air conditioner's operating mode: either anti-cold air mode or heating mode. If it's determined to be in anti-cold air mode, the heating element is activated to heat the air blown from the indoor unit's vents. This ensures that when the air conditioner is turned on in heating mode, the user can immediately feel the heating effect. This overcomes the drawbacks of existing air conditioners that blow cold air in the first few minutes of heating mode, or where the indoor unit's fan doesn't operate for the first few minutes after startup, resulting in no airflow from the indoor unit. This improves user comfort. To further enhance user comfort, when the air conditioner is operating in anti-cold air mode with the heating element activated, as the indoor unit's coil temperature T...p The increase in airflow correspondingly increases the fan speed of the indoor unit, allowing users to gradually feel the air conditioner blowing hotter air with stronger force, further enhancing the user's comfort experience.

[0057] like Figure 4 As shown, this embodiment of the invention also provides a control device for preventing cold air when an air conditioner is turned on for heating. The control device includes a data acquisition module 10 and a control module 20.

[0058] in,

[0059] Data acquisition module 10 is used to collect the coil temperature T of the indoor unit. p The data acquisition module 10 can be a temperature sensor that periodically collects the coil temperature T of the indoor unit. p For example, the indoor unit's coil temperature T is collected every 3 seconds. p .

[0060] Control module 20 is used to control the coil temperature T of the indoor unit collected by data acquisition module 10. p Determine whether the air conditioner is operating in anti-cold air mode or heating mode; and if the air conditioner is operating in anti-cold air mode, activate the heating device and base the operation on the coil temperature T. p Adjust the indoor unit's fan speed according to the changes.

[0061] Control module 20 reads the coil temperature T of the indoor unit collected by data acquisition module 10. p And set the indoor unit's coil temperature T p Compare with the first set temperature. If the coil temperature T p If the temperature exceeds the first set temperature, the control module 20 determines that the air conditioner is operating in heating mode and sends a command to the air conditioner to operate in heating mode. If the coil temperature T... p If the temperature is lower than the first set temperature, the control module 20 determines that the air conditioner is operating in anti-cold air mode and sends a command to the air conditioner to operate in anti-cold air mode, while simultaneously activating the heating device.

[0062] During the operation of the air conditioner in anti-cold air mode, the control module 20 reads the real-time coil temperature T of the indoor unit collected by the data acquisition module 10. p And based on the coil temperature T p The fan speed of the indoor unit of the air conditioner is adjusted accordingly to the change in temperature. For example, when the first set temperature is ≤ coil temperature T... p When the second set temperature is reached, the fan of the indoor unit is controlled to run at the second speed.

[0063] This invention also provides an air conditioner, which includes a memory and a processor. The memory stores a computer program, and when the computer program is executed by the processor, it implements the above-described control method for preventing cold air when the air conditioner is turned on for heating.

However, it will be readily understood by those skilled in the art that the scope of protection of the present invention is obviously not limited to these specific embodiments. Without departing from the principles of the present invention, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will all fall within the scope of protection of the present invention.
