Referring to fig. 1 and 2 together, an air conditioner 10 according to an embodiment of the present invention includes a temperature adjustment device 11, an air purification device 12, a memory 13, and a processor 14. The air cleaning device 12 includes a fresh air blower 122. The memory 13 stores a pre-stored temperature difference value, a pre-stored corresponding relationship between an indoor fan wind gear and a pre-stored fresh air fan wind gear, and stores at least one program.
Referring to fig. 3, a control method of an air conditioner according to an embodiment of the present invention is applied to an air conditioner 10. The control method comprises the following steps:
s1, determining a temperature difference between the indoor ambient temperature and the outdoor ambient temperature when the temperature adjustment device 11 is operating;
s2, detecting an indoor fan damper of the indoor fan 112 of the thermostat 11; and
and S3, determining the temperature difference between the indoor environment temperature and the outdoor environment temperature and the fresh air fan damper corresponding to the indoor fan damper according to the temperature difference between the pre-stored indoor environment temperature and the outdoor environment temperature and the corresponding relationship between the pre-stored indoor fan damper and the pre-stored fresh air fan damper, and controlling the fresh air fan 122 to operate at the fresh air fan damper.
The control method of the embodiment of the present invention may be implemented by the processor 14, that is, the processor 14 may be configured to execute at least one program to implement step S1 to determine the temperature difference between the indoor ambient temperature and the outdoor ambient temperature when the thermostat 11 is running. The processor 14 may be configured to execute at least one program to implement step S2 to detect an indoor fan damper operating the indoor fan 112 of the thermostat 11. The processor 14 may be configured to execute at least one program to implement step S3 to determine the temperature difference between the indoor ambient temperature and the outdoor ambient temperature and the new air fan damper corresponding to the indoor fan damper according to the temperature difference between the pre-stored indoor ambient temperature and the outdoor ambient temperature and the corresponding relationship between the pre-stored indoor fan damper and the pre-stored new air fan damper, and to control the new air fan 122 to operate with the new air fan damper.
The memory 13 may be a separate memory or a dedicated or dynamically allocated portion of the memory of the air conditioner 10. The processor 14 may be a stand-alone processor or a dedicated or dynamically assigned portion of the processor of the air conditioner 10.
The temperature adjusting device 11 and the air cleaning device 12 of the air conditioner 10 may be integrally provided. For example, for a cabinet, the temperature adjustment device 11 may be located above the air purification device 12. Of course, the air conditioner 10 may also be an on-hook, and is not particularly limited herein. The air conditioner 10 adjusts the indoor ambient temperature by the thermostat 11 to create a comfortable environment for the user. The thermostat 11 may operate in a cooling mode or a heating mode when activated. In the cooling mode of operation, the thermostat 11 absorbs heat from the indoor environment and releases it to the outside, so that the indoor environment temperature decreases. In the heating mode of operation, the thermostat 11 absorbs heat from the outdoor environment and releases it to the indoor, causing the indoor environment to increase in temperature.
When the temperature adjusting device 11 works, the indoor space is relatively closed, so that heat transfer is not easy to occur in the indoor environment and the outdoor environment. When the air conditioner 10 is used in a relatively closed indoor space for a long time, more dust, peculiar smell or harmful polluted gas is generated, certain harm is caused to the health of people, and health problems such as cold, air-conditioning diseases and the like can occur for a long time. The air cleaning device 12 may introduce fresh outdoor air to improve indoor air quality. However, the temperature difference between the indoor ambient temperature and the outdoor ambient temperature may cause the reduction of the cooling and heating comfort after the outdoor air is introduced, which may affect the user experience.
According to the control method and the air conditioner 10, the linkage between the wind level of the fresh air fan operated by the air purification device 12 and the wind level of the indoor fan operated by the temperature regulation device 11 is controlled by detecting the wind level of the indoor fan operated by the temperature regulation device 11 and combining the temperature difference value between the indoor environment temperature and the outdoor environment temperature, so that the regulation of the introduced fresh air volume can be realized, and the user can use the fresh air volume more comfortably and save energy.
In some embodiments, the control method comprises the steps of:
when the operation of the thermostat 11 is stopped, the air cleaning device 12 is controlled to be in a standby state.
In some embodiments, the processor 14 may control the air cleaning device 12 to be in a standby state when the thermostat 11 stops operating.
It can be understood that when the thermostat 11 stops operating, the thermostat 11 does not perform cooling or heating, and the indoor air can be kept clean by opening the doors and windows of the room to circulate the indoor and outdoor air. At this time, the air cleaning device 12 may be in a standby state without the air cleaning device 12 introducing outdoor air. When the air cleaning device 12 is in the standby state, the fresh air fan 122 stops rotating. This effectively reduces the power consumption of the air conditioner 10.
Referring to fig. 4, in some embodiments, step S1 includes:
s12, determining that the thermostat 11 is operating when the compressor 114 of the thermostat 11 is started;
s14, collecting indoor environment temperature and outdoor environment temperature; and
and S16, calculating the temperature difference between the indoor environment temperature and the outdoor environment temperature.
In some embodiments, steps S12, S14, and S16 may be implemented by the processor 14, or the processor 14 may be configured to execute at least one program to detect whether the compressor 114 of the thermostat 11 is activated, and determine that the thermostat 11 is operated when the compressor 114 of the thermostat 11 is activated. Processor 14 may be configured to execute at least one program to collect an indoor ambient temperature and an outdoor ambient temperature. The processor 14 may obtain the indoor ambient temperature through an indoor temperature sensor 15 located in the indoor unit, and obtain the outdoor ambient temperature through an outdoor temperature sensor 16 located in the outdoor unit. Processor 14 may be configured to execute at least one program to calculate a temperature difference between the indoor ambient temperature and the outdoor ambient temperature based on the collected indoor ambient temperature and outdoor ambient temperature.
In this way, the processor 14 may determine the temperature difference between the indoor ambient temperature and the outdoor ambient temperature so that the processor 14 controls the indoor fan damper of the temperature adjustment device 11 and the fresh air fan damper of the air purification device 12 to be linked according to the temperature difference between the indoor ambient temperature and the outdoor ambient temperature.
In some embodiments, the pre-stored temperature difference between the indoor ambient temperature and the outdoor ambient temperature, and the pre-stored correspondence between the indoor fan damper and the pre-stored fresh air fan damper include a curve or a look-up table.
It can be understood that when the air cleaning device 12 introduces the outdoor air into the room, the change of the indoor ambient temperature is related to the power of the operation of the temperature adjusting device 11, the temperature difference between the indoor ambient temperature and the outdoor ambient temperature, and the amount of the introduced outdoor air. The size of the indoor fan damper is related to the power at which the thermostat 11 operates. The amount of outdoor air introduced is related to the fresh air fan damper of the air purification device 12. In order to keep the comfort of the indoor environment temperature, the temperature difference between the indoor environment temperature and the outdoor environment temperature and the corresponding relationship between the indoor fan damper and the fresh air fan damper can be predetermined and made into a curve or a lookup table to be prestored in the memory 13, and the processor 14 controls the operation of the air conditioner 10 according to the corresponding relationship when in use.
Referring to fig. 5 to 10, in some embodiments, step S3 includes:
s31, when the temperature difference between the indoor ambient temperature and the outdoor ambient temperature is greater than or equal to the preset threshold and the wind level of the indoor fan is a high wind level, controlling the fresh air fan 122 to operate at a medium wind level; or
S32, when the temperature difference between the indoor ambient temperature and the outdoor ambient temperature is greater than or equal to the preset threshold and the wind level of the indoor fan is the medium wind level, controlling the fresh air fan 122 to operate at the low wind level; or
S33, when the temperature difference between the indoor ambient temperature and the outdoor ambient temperature is greater than or equal to the preset threshold and the wind level of the indoor fan is low, controlling the fresh air fan 122 to operate at low wind level; or
S34, when the temperature difference between the indoor ambient temperature and the outdoor ambient temperature is less than the preset threshold and the wind level of the indoor fan is high, controlling the fresh air fan 122 to operate at the high wind level; or
S35, when the temperature difference between the indoor environment temperature and the outdoor environment temperature is smaller than a preset threshold value and the wind gear of the indoor fan is a middle wind gear, controlling the fresh air fan 122 to operate at a high wind gear; or
And S36, when the temperature difference between the indoor environment temperature and the outdoor environment temperature is smaller than a preset threshold value and the wind gear of the indoor fan is a low wind gear, controlling the fresh air fan 122 to operate at a medium wind gear.
In some embodiments, step S31, step S32, step S33, step S34, step S35, or step S36 may be implemented by the processor 14, or the processor 14 may be configured to execute at least one program to control the fresh air fan 122 to operate at the medium wind range when the temperature difference between the indoor ambient temperature and the outdoor ambient temperature is greater than or equal to the preset threshold and the indoor fan wind range is the high wind range. The processor 14 may be configured to execute at least one program to control the fresh air fan 122 to operate in a low wind range when the temperature difference between the indoor ambient temperature and the outdoor ambient temperature is greater than or equal to a preset threshold and the indoor fan wind range is a medium wind range. The processor 14 may be configured to execute at least one program to control the fresh air fan 122 to operate in a low wind range when the temperature difference between the indoor ambient temperature and the outdoor ambient temperature is greater than or equal to a preset threshold and the indoor fan wind range is the low wind range. The processor 14 may be configured to execute at least one program to control the fresh air fan 122 to operate in a high wind range when the temperature difference between the indoor ambient temperature and the outdoor ambient temperature is less than the preset threshold and the wind range of the indoor fan is the high wind range. The processor 14 may be configured to execute at least one program to control the fresh air fan 122 to operate in a high wind range when the temperature difference between the indoor ambient temperature and the outdoor ambient temperature is less than the preset threshold and the indoor fan wind range is the medium wind range. The processor 14 may be configured to execute at least one program to control the fresh air fan 122 to operate at a medium wind gear when the temperature difference between the indoor ambient temperature and the outdoor ambient temperature is less than the preset threshold and the indoor fan wind gear is a low wind gear.
It will be appreciated that when a user uses the air conditioner 10, the target temperature is often set as desired, for example, by a remote control, and the air conditioner 10 determines a target temperature range based on the target temperature and selects to activate the cooling mode or the heating mode such that the indoor ambient temperature is reduced or increased to the target temperature range. When the difference between the indoor environment temperature and the target temperature range is large, the indoor fan 112 operates a high wind level to rapidly decrease or increase the indoor environment temperature to the target temperature range. When the indoor ambient temperature and the target temperature range are small, the indoor fan 112 operates the medium damper to reduce or increase the indoor ambient temperature to the target temperature range to avoid the indoor ambient temperature from fluctuating greatly. When the indoor ambient temperature reaches the target temperature range, the thermostat 11 operates the low wind level to keep the indoor ambient temperature within the target temperature range.
It can be understood that the indoor fans 112 with different wind ranges have the relationship of the high wind range being larger than the medium wind range, and the medium wind range being larger than the low wind range.
The rotation speed of the fresh air fan 122 with different wind ranges is related to that the high wind range is larger than the medium wind range, and the medium wind range is larger than the low wind range. Specifically, in some embodiments, the fresh air fan 122 operates at a high wind speed, and the rate of introduction of outdoor air is 100m3H is used as the reference value. When the fresh air fan 122 is in operation at a medium wind level, the rate of introducing outdoor air is 60m3H is used as the reference value. When the fresh air fan 122 operates at a low wind level, the rate of introducing outdoor air is 30m3/h。
When the temperature difference between the indoor environment temperature and the outdoor environment temperature is greater than or equal to the preset threshold, the difference between the indoor environment temperature and the outdoor environment temperature is large, and the influence of introduced outdoor air on the indoor environment temperature is large. When the temperature difference between the indoor environment temperature and the outdoor environment temperature is smaller than the preset threshold, the difference between the indoor environment temperature and the outdoor environment temperature is smaller, and the influence of the introduced outdoor air on the indoor environment temperature is smaller. In this way, the air conditioner 10 can control the fresh air fan damper of the air purification device 12 according to the temperature difference between the indoor environment temperature and the outdoor environment temperature and the indoor fan damper, so that the influence of the amount of the introduced outdoor air on the indoor environment temperature is smaller than the influence of the cooling or heating of the air conditioner 10 on the indoor environment temperature.
Specifically, the preset threshold may be flexibly configured as needed. Wherein the preset threshold is greater than or equal to 8 ℃ and less than or equal to 20 ℃. In some embodiments, the preset threshold value may also be set to different temperature values depending on the operation mode of the thermostat 11.
Specifically, in some embodiments, the preset threshold may be 13 ℃ when the thermostat 11 is operating in the cooling mode.
In some embodiments, the preset threshold may be 20 ℃ when the thermostat 11 operates in the heating mode.
Referring again to fig. 1 and 2, in some embodiments, the air purification apparatus 12 is formed with an air duct 124 for communicating the indoor and outdoor. The air purification apparatus 12 includes an air filtration module 126 disposed within the air duct 124.
In this manner, the air cleaning device 12 introduces the outdoor air through the duct 124, and filters the introduced outdoor air through the air filtering module 126.
Specifically, the air cleaning device 12 includes an air inlet 121 and an air outlet 123, and the air duct 124 communicates with the outside through the air inlet 121 and communicates with the inside through the air outlet 123. The air filtration module 126 may include an antimicrobial and mold-proof primary screen, a sponge activated carbon layer, a honeycomb activated carbon layer, and a high efficiency screen. When the fresh air fan 122 operates, outdoor air is sucked from the air inlet 121, and the filtered outdoor air is sent out from the air outlet 123 through the air duct 124. Therefore, indoor air can be purified, and the indoor environment is more comfortable.
