The specific meaning of the above terms in the present application will be understood in specific cases by those of ordinary skill in the art.
According to the embodiment of the application, the air conditioner heats or cools indoor air entering from the return air inlet through the indoor heat exchanger, when the indoor heat exchanger works as a condenser, the indoor heat exchanger works as an evaporator, the fan controls the speed of heating, refrigerating and purifying the indoor air through the adjustment of the wind speed, the air supply temperature sensor is used for detecting the air supply temperature of the air conditioner, namely the output temperature of the air conditioner, and the electric auxiliary heating module is used for assisting the air conditioner to heat.
As shown in fig. 1 and 2, indoor air enters through the air return flange (1), is sent into the indoor heat exchanger (4) through the fan volute (2)/(9) and the air supply channel (3)/(8), is heated or cooled through the indoor heat exchanger (4), is purified through the negative ion module (12), kills bacteria or pollutants carried in the air, and is finally sent into a room through the air supply flange (5). Wherein, T1 and T2 temperature sensor detects return air temperature and air supply temperature respectively, and pollutant concentration detection module (11) are used for detecting PM 2.5/particulate matter concentration such as formaldehyde/TVOC. TVOC (Total Volatile Organic Compounds ), which generally refers to organic compounds with saturated vapor pressure exceeding 133.32pa at room temperature, is one of the more serious influences in the pollution of indoor air quality.
To further describe the solution of the present application, in one example of the present application, the air conditioner includes:
an indoor heat exchanger (4) that operates as a condenser or an evaporator;
the fan is arranged between the air return opening and the air inlet channel;
an air supply temperature sensor T2 for detecting an air supply temperature of the air conditioner;
an outdoor temperature sensor for detecting an outdoor ambient temperature;
a pollutant concentration detection module (11) for detecting the indoor pollutant concentration;
the negative ion module (12) is arranged between the indoor heat exchanger and the air supply outlet and is used for purifying indoor air;
a controller configured to:
acquiring the indoor pollutant concentration and the air supply temperature;
determining an operation mode of the air conditioner according to the month in which the current date is located or the outdoor environment temperature, wherein the modes comprise an automatic mode, a summer mode and a winter mode;
when the air conditioner is in an automatic mode, controlling the negative ion module according to the indoor pollutant concentration, and controlling the wind speed of a fan according to the indoor pollutant concentration;
when the air conditioner is in summer mode or winter mode, the anion module is controlled according to the indoor pollutant concentration, and the fan speed is controlled according to the air supply temperature and the indoor pollutant concentration.
In the embodiment of the application, the pollutants comprise PM2.5, formaldehyde, TVOC and other harmful pollutants, and the operation mode of the air conditioner is determined according to the month of the current date, wherein the operation mode of the air conditioner corresponding to the specific month can be set by a person skilled in the art according to the local climate in which the air conditioner is installed, generally speaking, the month corresponding to the automatic mode is moderate in local air temperature, and air conditioning heating or cooling is not needed generally; in the months corresponding to the summer mode, the local air temperature is hot, and air conditioning is needed to be used for refrigeration; in the months corresponding to the winter mode, the local air temperature is relatively cold, and the air conditioner is required to be used for heating. Alternatively, the operation mode of the air conditioner may be controlled by an outdoor temperature or a combination of outdoor and indoor temperatures, wherein the outdoor temperature may be collected by a user setting, which falls within the protection scope of the present application. When the air conditioner is in an automatic mode, the air conditioner generally does not use heating or refrigerating at the moment, so that the air speed of the fan is controlled only through the indoor pollutant concentration, the negative ion module is controlled to be opened or closed according to the indoor pollutant concentration, and the air speed of the fan can be used for determining the air purifying speed. Meanwhile, when the air conditioner is in summer mode or winter mode, the heating or refrigerating function of the air conditioner can be used at the moment, so that the anion module is controlled according to the indoor pollutant concentration, and the wind speed of the fan is controlled according to the air supply temperature and the indoor pollutant concentration.
To accurately control the speed of an air conditioner purge air conditioner, in some embodiments, the controller is configured to:
when the air conditioner is in an automatic mode and the indoor pollutant concentration is greater than or equal to a second preset threshold value, starting the negative ion module, and controlling the wind speed to be a preset high wind operation wind speed;
when the air conditioner is in an automatic mode and the indoor pollutant concentration is greater than or equal to a first preset threshold value and smaller than a second preset threshold value, the negative ion module is started, and the wind speed is controlled to be the preset low wind running wind speed.
In this embodiment, when the air conditioner is in the automatic mode, it is indicated that the air conditioner does not need to heat or heat, and only the concentration of indoor pollutants is considered to control the speed of the purified air at this time, and when the concentration of indoor pollutants is greater than or equal to a second preset threshold value, the negative ion module is turned on, and the fan wind speed is controlled to be the preset high wind operation wind speed. The second preset threshold is greater than the first preset threshold, and optionally, the first preset threshold is a standard value of indoor pollutant concentration, and the second preset threshold is an integer multiple of the standard value. The preset high wind running wind speed is the high wind speed set in advance by the air conditioner, and the specific value can be adjusted according to the actual situation. When the air conditioner is in an automatic mode and the indoor pollutant concentration is greater than or equal to a first preset threshold value and smaller than a second preset threshold value, the fact that the pollutant concentration exceeds the standard at the moment is indicated that the negative ion module is required to be started, but the wind speed is controlled to be the preset low wind operation wind speed because the pollutant concentration exceeds the standard and is not particularly high.
It should be noted that the solution of the above preferred embodiment is only one specific implementation solution provided by the present application, and other methods for controlling the wind speed of the fan according to the indoor pollutant concentration are all within the protection scope of the present application.
To ensure user comfort while reasonably adjusting air purification speed, in some embodiments, the air conditioner further comprises an electrically assisted thermal module, the controller configured to:
when the air conditioner is in a winter mode, the indoor pollutant concentration is larger than or equal to a first preset threshold value, the air supply temperature is smaller than the first preset temperature, and an instruction for starting the electric auxiliary thermal module is not received at the same time, the negative ion module is started, and the air speed is controlled to be a preset breeze operation air speed;
when the air conditioner is in a winter mode, the concentration of the indoor pollutants is larger than or equal to a first preset threshold value, the air supply temperature is larger than or equal to the first preset temperature and smaller than a second preset temperature, and meanwhile, an instruction for starting the electric auxiliary heating module is not received, the negative ion module is started, and the air speed is controlled to be a preset low-air running air speed;
when the air conditioner is in winter mode, the concentration of the indoor pollutants is larger than or equal to a first preset threshold value, and the air supply temperature is larger than or equal to a second preset temperature, starting the negative ion module, and controlling the wind speed to be the preset high wind operation wind speed;
When the air conditioner is in winter mode and the indoor pollutant concentration is greater than or equal to a first preset threshold value, and the air supply temperature is smaller than a second preset temperature, and simultaneously, the instruction for starting the electric auxiliary thermal module is received, the negative ion module is started, and the wind speed is controlled to be the preset high wind operation wind speed.
In this embodiment, the electric auxiliary thermal module is configured to assist the air conditioner to heat by heating the resistance wire when the air conditioner performs a heating function, and optionally, the electric auxiliary thermal module is turned on after receiving an opening instruction of a user. After the electric auxiliary thermal module is started, because the heating efficiency is improved, the influence on cold air blowing of a user is small when the air speed of the air conditioner is high, so that the air speed of the fan can be controlled to be the preset high-wind running air speed, and optionally, the air speed can be adjusted according to a user control instruction after the electric auxiliary thermal module is started.

In order to further explain the technical idea of the present invention, the present invention also provides a control method for the purifying function of an air conditioner, the method is applied to an air conditioner including an indoor heat exchanger, a fan, an air supply temperature sensor, an outdoor temperature sensor, an electric auxiliary heat module, a pollutant concentration detection module, a negative ion module and a controller, as shown in fig. 3, the specific steps of the method are as follows:
s301, acquiring indoor pollutant concentration and air supply temperature.
In this step, the indoor contaminant concentration detected by the contaminant concentration detection module and the air supply temperature detected by the air supply temperature sensor are obtained.
S302, determining an operation mode of the air conditioner according to the month in which the current date is located or the outdoor environment temperature, wherein the modes comprise an automatic mode, a summer mode and a winter mode.
In this step, the operation mode of the air conditioner is determined according to the month in which the current date is located, wherein, the operation mode of the air conditioner corresponding to the specific month can be set by a person skilled in the art according to the local climate in which the air conditioner is installed, in general, the month corresponding to the automatic mode should have moderate local air temperature, and air conditioning heating or cooling is generally not needed; in the months corresponding to the summer mode, the local air temperature is hot, and air conditioning is needed to be used for refrigeration; in the months corresponding to the winter mode, the local air temperature is relatively cold, and the air conditioner is required to be used for heating. For example, 7 to 9 months may be set as a month corresponding to the summer mode, 12 to 2 months may be set as a month corresponding to the winter mode, and the remaining months may be set as months corresponding to the automatic mode, or the operation mode of the air conditioner may be controlled by the outdoor temperature or the combination of the outdoor and indoor temperatures.

In this step, when the air conditioner is in the automatic mode, the air conditioner generally does not use heating or cooling at this time, so the wind speed of the fan is controlled only by the indoor pollutant concentration, and the negative ion module is controlled to be turned on or off according to the indoor pollutant concentration.
In order to accurately control the speed of the air conditioner for purifying the air, in some embodiments, when the air conditioner is in an automatic mode, the anion module is controlled according to the indoor pollutant concentration, and the wind speed of the fan is controlled according to the indoor pollutant concentration, specifically:
when the indoor pollutant concentration is greater than or equal to a second preset threshold value, starting the negative ion module, and controlling the wind speed to be a preset high wind operation wind speed;
when the indoor pollutant concentration is larger than or equal to a first preset threshold value and smaller than a second preset threshold value, starting the negative ion module, and controlling the wind speed to be the preset low wind operation wind speed.
Specifically, when the air conditioner is in an automatic mode, the air conditioner is not required to be heated or heated, at the moment, the speed of purifying air is controlled by only considering the concentration of indoor pollutants, and when the concentration of the indoor pollutants is greater than or equal to a second preset threshold value, the negative ion module is started, and the wind speed of the fan is controlled to be the preset high wind operation wind speed. When the indoor pollutant concentration is greater than or equal to the first preset threshold value and smaller than the second preset threshold value, the fact that the pollutant concentration exceeds the standard at the moment is indicated that the negative ion module is required to be started, but the wind speed is controlled to be the preset low wind operation wind speed because the pollutant concentration exceeds the standard and is not particularly high.
S304, when the air conditioner is in summer mode or winter mode, controlling the anion module according to the indoor pollutant concentration, and controlling the wind speed of the fan according to the air supply temperature and the indoor pollutant concentration.

Specifically, after the electric auxiliary thermal module is started, because the heating efficiency is improved, even if the air speed of the air conditioner is high, the influence on cold air blowing of a user is small, so that the air speed of the fan can be controlled to be the preset high-wind running air speed, and optionally, after the electric auxiliary thermal module is started, the air speed can be adjusted according to a user control instruction. When the electric auxiliary heating module is not started, the air conditioner is in a winter mode and has heating requirements, at the moment, the air conditioner heats only through the automatic indoor heat exchanger, the efficiency is relatively low, when the concentration of indoor pollutants is larger than or equal to a first preset threshold value, the air purification requirements and the heating requirements need to be comprehensively considered after the negative ion module is started, at the moment, when the air supply temperature is smaller than a first preset temperature, in order to prevent cold air blowing, the air speed of the control fan is the preset breeze operation air speed, when the air supply temperature is larger than or equal to the first preset temperature and smaller than a second preset temperature, the output temperature of the air conditioner is still lower, the air speed of the control fan is the preset low breeze operation air speed, and when the air supply temperature is larger than or equal to the second preset temperature, the output temperature of the air conditioner is higher, and the air speed can be controlled to be the preset high breeze operation air speed.
