Detailed ways

Embodiments of the present invention are described in detail below, examples of which are shown in the drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary, are only for explaining the embodiments of the present invention, and should not be construed as limiting the embodiments of the present invention.

Referring to FIGS. 1-3 , an air conditioner 100 according to an embodiment of the present invention includes an air cleaning device 10 . The control method of the air conditioner includes the following steps:

S10, when the outdoor air temperature T1 is greater than the indoor air temperature T2 (T1>T2), determine whether the difference between the outdoor air dew point temperature T3 and the indoor air temperature T2 is smaller than a first threshold Ta;

S20, when the difference between the dew point temperature T3 of the outdoor air and the indoor air temperature T2 is smaller than the first threshold Ta, the fan 16 of the air cleaning device 10 is controlled to start and work at a first preset speed R1 to introduce outdoor air into the room.

The air conditioner 100 according to the embodiment of the present invention includes an air cleaning device 10 , a memory 30 and a processor 40 . The memory 30 stores at least one program, and the processor 40 is configured to execute the at least one program. As an example, the air conditioner control method according to the embodiment of the present invention can be implemented by the air conditioner 100 according to the embodiment of the present invention, and can be applied to the air conditioner 100 .

Wherein, the steps S10 to S20 of the control method of the air conditioner in the embodiment of the present invention can be implemented by the processor 40 . That is to say, the processor 40 is used to execute the program to realize whether the difference between the dew point temperature T3 of the outdoor air and the indoor air temperature T2 is smaller than the first threshold Ta when the outdoor air temperature T1 is greater than the indoor air temperature T2; When the difference between the dew point temperature T3 and the indoor air temperature T2 is less than the first threshold Ta, the fan 16 of the air cleaning device 10 is controlled to start and work at a first preset speed R1 to introduce outdoor air into the room.

The air conditioner control method and the air conditioner 100 in the embodiment of the present invention control the operation of the blower fan 16 of the air purification device 10 through the difference between the dew point temperature T3 of the outdoor air and the indoor air temperature T2, so that when the outdoor fresh air is introduced, it can Avoid condensation of the air entering the air purification device 10 and affect the performance of the air conditioner 100 , and the embodiment of the present invention can improve the comfort of the indoor environment and provide good user experience.

It can be understood that the storage 30 may be an independent storage 30 or a dedicated or dynamically allocated part of the storage 30 of the air conditioner 100 . The processor 40 may be an independent processor 40 or a dedicated or dynamically allocated part of the processor 40 of the air conditioner 100 .

Please refer to FIG. 1 again, the air purification device 10 may be a fresh air blower device, and the air purification device 10 includes an air inlet 12 , a filter 14 , a fan 16 and an air outlet 19 . The processor 40 controls the blower fan 16 to rotate at a certain wind speed so that the air inlet 12 introduces outdoor fresh air into the room, and the introduced air is filtered through the filter screen 14. , honeycomb activated carbon layer and high-efficiency filter. The processor 40 controls the fan 16 to send the filtered air out through the air outlet 19 . In this way, the indoor air can be purified, which is more beneficial to the user's health. In the embodiment of the present invention, the air passage in the air purification device 10 is roughly in a Z shape. In one example, the outdoor air temperature at the air inlet 12 can be detected to determine the dew point temperature T3 of the outdoor air.

The dew point temperature of air refers to the temperature when the air is cooled to saturation without changing the water vapor content and air pressure. If the temperature of the air is higher than the dew point temperature of the air, the air is in an unsaturated state at this time; if the air temperature is lower than the dew point temperature of the air, the air is in a saturated state at this time, and the air will condense into small water droplets, that is to say, the air has condensed Lu's situation.

In the related technology, when the outdoor air temperature T1 is greater than the indoor air temperature T2 (T1>T2), and the air conditioner turns on the fresh air function, the air with a higher temperature outside enters the fresh fan device, and the temperature of the inner wall surface of the air duct of the fresh fan device It is relatively low, which will easily lead to condensation of the relatively high-temperature outdoor air entering the fresh air device, and condense into small water droplets, thereby affecting the performance of the fresh air device, and the user experience is not good.

However, in the embodiment of the present invention, by judging whether the difference between the dew point temperature T3 of the outdoor air and the indoor air temperature T2 is smaller than the first threshold Ta, the difference between the dew point temperature T3 of the outdoor air and the indoor air temperature T2 is smaller than the first threshold Ta When the fan 16 of the air cleaning device 10 is started, it starts and introduces the outdoor air into the room at the first preset speed R1, so as to avoid the condensation of the outdoor air entering the room due to the excessive temperature difference between the outdoor temperature and the indoor temperature. Happening.

It should be noted that if the difference between the dew point temperature T3 of the outdoor air and the indoor air temperature T2 reaches the first threshold value Ta, and the first threshold value Ta is the wind speed of the fresh fan device when air with a relatively high temperature outside enters the fresh fan device. The air at the inner wall of the pipe just happens to be the critical value of condensation. That is to say, when the difference between the dew point temperature T3 of the outdoor air and the temperature T2 of the indoor air is smaller than the first threshold value Ta, the air conditioner 100 will not have the risk of condensation or the probability of condensation will be extremely low. When the dew point of the outdoor air When the difference between the temperature T3 and the indoor air temperature T2 is not less than the first threshold Ta, the air conditioner 100 may have a risk of condensation.

It should be pointed out that the first threshold Ta and the first preset rotational speed R1 can be set according to actual conditions.

In one example, the range of the first threshold Ta can be set as 0°C<Ta<14°C. When the range of the first threshold Ta is 9°C≤Ta<14°C, the first preset speed R1 is a low speed, for example, 0r/min<R1≤400r/min; when the range of the first threshold Ta is 5°C≤ Ta<9°C, the first preset speed R1 is a medium speed, for example, 400r/min<R1≤800r/min; when the range of the first threshold Ta is 0°C<Ta<5°C, the first preset speed R1 is High speed, for example, 800r/min<R1≤1200r/min.

That is to say, there is a negative correlation between the magnitude of the first threshold Ta and the magnitude of the first preset rotational speed R1. It can be understood that the smaller the first threshold Ta is, the larger the first preset rotational speed R1 is, or in other words, the smaller the difference between the dew point temperature T3 of the outdoor air and the indoor air temperature T2 is, the processor 40 controls the fan of the air cleaning device 10 to The speed of 16 is also greater. The advantage of this is that when the above-mentioned difference falls into the smaller first threshold Ta, the above-mentioned difference is small, so the rotating speed of the blower fan 16 can be appropriately increased to quickly introduce fresh air; when the above-mentioned difference falls into the relative When the first threshold Ta is large, the above-mentioned difference is relatively large, so the speed of the fan 16 can be appropriately reduced to slowly introduce fresh air; when the above-mentioned difference falls into a larger first threshold Ta, the above-mentioned difference is more Large, so the rotating speed of blower fan 16 can be appropriately further reduced to introduce fresh air more slowly.

In this way, by adjusting the corresponding relationship between the first threshold Ta and the first preset rotational speed R1, the amount of air entering the room can be adjusted while condensation of the air can be avoided, thereby improving the comfort of the environment and the user experience. it is good.

Specifically, in an example, the range of the first threshold Ta is 9°C≤Ta<14°C, the outdoor air temperature T1 is 40°C, and the relative humidity is 60%. At this time, the corresponding outdoor air temperature can be obtained through a lookup table or curve The dew point temperature T3 is 30.93 degrees Celsius. If the indoor air temperature T2 is 21 degrees Celsius at this time, the difference between the dew point temperature T3 of the outdoor air and the indoor air temperature T2 is 9.93 degrees Celsius, because the difference (9.93 degrees Celsius) falls within the range of the first threshold Ta 9°C≤Ta <14°C, so the processor 40 controls the fan 16 of the air cleaning device 10 to start and introduce outdoor air into the room at a low speed (for example, 100r/min).

In another example, the range of the first threshold Ta is 5°C≤Ta<9°C, the outdoor air temperature T1 is 40°C, and the relative humidity is 60%. At this time, the corresponding dew point of the outdoor air can be obtained through a lookup table or curve The temperature T3 is 30.93 degrees Celsius. If the indoor air temperature T2 is 23 degrees Celsius at this time, the difference between the dew point temperature T3 of the outdoor air and the indoor air temperature T2 is 7.93 degrees Celsius, because the difference (7.93 degrees Celsius) falls within the range of the first threshold Ta 5°C≤Ta <9°C, so the processor 40 controls the fan 16 of the air cleaning device 10 to start and introduce outdoor air into the room at a medium speed (eg, 800r/min).

In yet another example, the range of the first threshold Ta is 0°C<Ta<5°C, the outdoor air temperature T1 is 40°C, and the relative humidity is 60%. At this time, the corresponding dew point of the outdoor air can be obtained through a lookup table or curve The temperature T3 is 30.93 degrees Celsius. If the indoor air temperature T2 is 26 degrees Celsius at this time, the difference between the dew point temperature T3 of the outdoor air and the indoor air temperature T2 is 4.93 degrees Celsius, because the difference (4.93 degrees Celsius) falls into the range of the first threshold Ta is 0°C< If Ta<5°C, the processor 40 controls the fan 16 of the air purification device 10 to start and introduce outdoor air into the room at a high speed (for example, 1200r/min).

The look-up table or curve can be stored in the air conditioner 100 or obtained by the air conditioner 100 from the cloud. It can be understood that the first threshold may also be a value instead of a range. For example, the first threshold may be set to a specific value such as 5, 8 or 10.

In some embodiments, the air conditioner 100 includes a temperature regulating device 20, and the control method includes the steps of:

S30, when the difference between the dew point temperature T3 of the outdoor air and the indoor air temperature T2 is greater than or equal to the first threshold Ta, control the air purification device 10 to stop working, and control the temperature adjustment device 20 to cool down.

Step S30 of the air conditioner control method in the embodiment of the present invention may be implemented by the processor 40 . That is to say, the processor 40 is used to execute the program to control the air cleaning device 10 to stop working when the difference between the dew point temperature T3 of the outdoor air and the indoor air temperature T2 is greater than or equal to the first threshold Ta, and to control the temperature adjustment device 20. Refrigeration.

Because in this embodiment, when the difference between the dew point temperature T3 of the outdoor air and the indoor air temperature T2 is greater than or equal to the first threshold value Ta, the air cleaning device 10 is controlled to stop working, and the temperature regulating device 20 is controlled to cool, so, in the air conditioner In the cooling mode of the air conditioner 100, condensation can be avoided, thereby improving the performance of the air conditioner 100.

Specifically, the temperature adjustment device 20 and the air purification device 10 in this embodiment are integrated. For example, for a cabinet machine, the temperature adjustment device 20 may be located above the air cleaning device 10 . Of course, the air conditioner 100 is still on-hook, and no specific limitation is made here. The thermostat 20 can be used for cooling or heating. In this embodiment, the temperature adjustment device 20 is used for cooling.

It can be understood that the range of the first threshold Ta can be set as 0°C<Ta<14°C. In one embodiment, the outdoor air temperature T1 is 40 degrees Celsius and the relative humidity is 60%, and the corresponding outdoor air dew point temperature T3 is 30.93 degrees Celsius. If the indoor air temperature T2 is 16 degrees Celsius at this time, the difference between the dew point temperature T3 of the outdoor air and the indoor air temperature T2 is 14.93 degrees Celsius. Since the difference (14.93 degrees Celsius) is not within the range of the first threshold Ta, T is 0℃< If Ta<14°C, the processor 40 controls the fan 16 of the air cleaning device 10 to stop working. At this time, the processor 40 may control the temperature regulating device 20 to operate for cooling, so that the air conditioner 100 is in a cooling mode.

Please refer to FIG. 4 , in some embodiments, the dew point temperature T3 of the outdoor air in step S10 is obtained through the following steps:

S12, collecting outdoor air temperature T1 and outdoor air humidity RH1; and

S14. Determine the dew point temperature T3 of the outdoor air corresponding to the outdoor air temperature T1 and the outdoor air humidity RH1 according to the relationship data of the pre-stored air temperature, the pre-stored air humidity and the pre-stored dew point temperature.

In this way, the dew point temperature T3 of the outdoor air can be obtained quickly.

Specifically, please refer to FIG. 3 again. The air conditioner 100 includes an outdoor temperature sensor 50 and an outdoor humidity sensor 60. The outdoor temperature sensor 50 is used to detect the outdoor air temperature T1, and the outdoor humidity sensor 60 is used to detect the outdoor air humidity RH1.

It can be understood that the relationship data of the pre-stored air temperature, the pre-stored air humidity and the pre-stored dew point temperature includes a curve or a look-up table, that is to say, the processor 40 can collect the outdoor air temperature T1 and The outdoor air humidity RH1, and the corresponding outdoor air dew point temperature T3 can be found through a curve or a lookup table.

Referring to Figure 5, in some implementations, the control method includes the steps of:

S40, when the outdoor air temperature T1 is lower than the indoor air temperature T2 (T1<T2), determine whether the difference between the indoor air dew point temperature T4 and the outdoor air temperature T1 is smaller than a second threshold Tb;

S50, when the difference between the dew point temperature T4 of the indoor air and the outdoor air temperature T1 is smaller than the second threshold Tb, the fan 16 of the air cleaning device 10 is controlled to start and work at a second preset speed R2 to introduce outdoor air into the room.

Steps S40 to S50 of the air conditioner control method in the embodiment of the present invention may be implemented by the processor 40 . That is to say, the processor 40 is used to execute the program to realize whether the difference between the dew point temperature T4 of the indoor air and the outdoor air temperature T1 is less than the second threshold Tb when the outdoor air temperature T1 is lower than the indoor air temperature T2; When the difference between the dew point temperature T4 and the outdoor air temperature T1 is less than the second threshold Tb, the fan 16 of the air cleaning device 10 is controlled to start and work at a second preset speed R2 to introduce outdoor air into the room.

In the related technology, when the outdoor air temperature T1 is lower than the indoor air temperature T2 (T1<T2), and the air conditioner turns on the fresh air function, the air with a lower outdoor temperature enters the fresh fan device, and the temperature of the outer wall of the indoor fresh fan device However, the temperature of the inner wall surface of the air duct of the fresh fan device is relatively low, which will easily lead to condensation of the indoor air at the outer wall of the fresh fan device located indoors when the outdoor air with a lower temperature is introduced, and the air condenses into small water beads, thus affecting the performance of the fresh air fan device, and the user experience is not good.

The air conditioner control method of the embodiment of the present invention controls the operation of the fan 16 of the air purification device 10 through the difference between the dew point temperature T4 of the indoor air and the outdoor air temperature T1. Condensation occurs in the indoor air and affects the performance of the air conditioner 100, and the implementation of the present invention can improve the comfort of the indoor environment, and the user experience is good.

It should be noted that if the difference between the dew point temperature T4 of the indoor air and the outdoor air temperature T1 is the second threshold Tb, and the second threshold Tb is the outer wall of the air duct of the fresh fan device when air with a lower outdoor temperature enters the fresh fan device The indoor air at the place is just the critical value where condensation will not occur. That is to say, when the difference between the dew point temperature T4 of the indoor air and the outdoor air temperature T1 is smaller than the second threshold Tb, the air conditioner 100 does not have the risk of condensation or the risk of condensation is extremely low. When the dew point temperature of the indoor air When the difference between T4 and the outdoor air temperature T1 is not less than the second threshold Tb, there is a risk of condensation in the air conditioner 100 .

It should be pointed out that the second threshold Tb and the second preset speed R2 can be set according to actual conditions.

In this embodiment, the range of the second threshold Tb may be set as 0°C<Tb<17°C. When the range of the second threshold Tb is 7°C≤Tb<17°C, the second preset speed R2 is a low speed, such as 0r/min<R2≤400r/min; when the range of the second threshold Tb is 3°C≤Tb <7°C, the second preset speed R2 is medium speed, for example, 400r/min<R2≤800r/min; when the range of the second threshold Tb is 0°C<Tb<3°C, the second preset speed R2 is high speed , such as 800r/min<R2≤1200r/min.

That is to say, there is a negative correlation between the magnitude of the second threshold Tb and the magnitude of the second preset rotational speed R2. It can be understood that the smaller the second threshold Tb is, the larger the second preset rotational speed R2 is, that is, the smaller the difference between the dew point temperature T4 of the indoor air and the outdoor air temperature T1 is, the processor 40 controls the temperature of the air cleaning device 10 to The rotating speed of fan 16 is also just bigger.

The advantage of this is that when the above-mentioned difference falls into the smaller second threshold Tb, the above-mentioned difference is small, so the rotating speed of the blower fan 16 can be appropriately increased to quickly introduce fresh air; When the second threshold Tb is large, the above-mentioned difference is relatively large, so the speed of the fan 16 can be appropriately reduced to slowly introduce fresh air; when the above-mentioned difference falls into a larger second threshold Tb, the above-mentioned difference is more Large, so the rotating speed of blower fan 16 can be appropriately further reduced to introduce fresh air more slowly.

In this way, by adjusting the corresponding relationship between the second threshold Tb and the second preset rotational speed R2, the amount of air entering the room can be adjusted while condensation of the air can be avoided, thereby improving the comfort of the environment and improving user experience. it is good.

Specifically, in an example, the range of the second threshold Tb is 7°C≤Tb<17°C, the indoor air temperature T2 is 25°C, and the relative humidity is 60%. At this time, the corresponding indoor air temperature can be obtained through a lookup table or curve The dew point temperature T4 is 16.72 degrees Celsius. If the temperature T1 of the outdoor air is 7 degrees Celsius at this time, the difference between the dew point temperature T4 of the indoor air and the temperature T1 of the outdoor air is 9.72 degrees Celsius, because the difference (9.72 degrees Celsius) falls within the range of the second threshold Tb of 7 degrees Celsius ≤Tb<17°C, so the processor 40 controls the fan 16 of the air cleaning device 10 to start and introduce outdoor air into the room at a low speed (for example, 100r/min). In another example, the range of the second threshold Tb is 3°C≤Tb<7°C, the indoor air temperature T2 is 25°C, and the relative humidity is 60%. At this time, the corresponding dew point of the indoor air can be obtained through a lookup table or curve The temperature T4 is 16.72 degrees Celsius. If the temperature T1 of the outdoor air is 11 degrees Celsius at this time, the difference between the dew point temperature T4 of the indoor air and the temperature T1 of the outdoor air is 5.72 degrees Celsius, because the difference (5.72 degrees Celsius) falls within the range of the second threshold Tb 3°C≤ If Tb<7°C, the processor 40 controls the fan 16 of the air cleaning device 10 to start and introduce outdoor air into the room at a medium speed (for example, 800r/min). In yet another example, the range of the second threshold Tb is 0°C<Tb<3°C, the indoor air temperature T2 is 25°C, and the relative humidity is 60%. At this time, the corresponding dew point of the indoor air can be obtained through a lookup table or curve The temperature T4 is 16.72 degrees Celsius. If the outdoor air temperature T1 is 15 degrees Celsius at this time, the difference between the dew point temperature T4 of the indoor air and the outdoor air temperature T1 is 1.72 degrees Celsius, because the difference (1.72 degrees Celsius) falls within the range of the second threshold Tb is 0°C< If Tb<3°C, the processor 40 controls the fan 16 of the air purification device 10 to start and introduce outdoor air into the room at a high speed (for example, 1200r/min).

It can be understood that the second threshold Tb may also be a value instead of a range. For example, the second threshold Tb can be set to a specific value such as 4, 7 or 11.

In some embodiments, the air conditioner 100 includes a temperature regulating device 20, and the control method includes the steps of:

S60, when the difference between the dew point temperature T4 of the indoor air and the outdoor air temperature T1 is greater than or equal to the second threshold Tb, control the air purification device 10 to stop working, and control the temperature adjustment device 20 to heat.

Step S60 of the air conditioner control method in the embodiment of the present invention can be implemented by the processor 40 . That is to say, the processor 40 is used to execute the program to realize that when the difference between the dew point temperature T4 of the indoor air and the outdoor air temperature T1 is greater than or equal to the second threshold Tb, the air purification device 10 is controlled to stop working, and the temperature adjustment device 20 is controlled to stop working. Heating.

Since in this embodiment, in the heating mode, the air purification device 10 is controlled to stop working when the difference between the dew point temperature T4 of the indoor air and the outdoor air temperature T1 is greater than or equal to the second threshold Tb, so that the air conditioner can be avoided Condensation occurs in the air conditioner 100, thereby improving the performance of the air conditioner 100.

It can be understood that the range of the second threshold Tb can be set as 0°C<Tb<17°C. In one embodiment, when the air conditioner 100 is in the heating mode (that is, when the temperature adjustment device 20 is heating), the indoor air temperature T2 is 25 degrees Celsius, and the relative humidity is 60%. At this time, the corresponding dew point temperature of the indoor air is T4 is 16.72 degrees Celsius. If the outdoor air temperature T1 is -1 degree Celsius at this time, the difference between the dew point temperature T4 of the indoor air and the outdoor air temperature T1 is 17.72 degrees Celsius, since the difference (17.72 degrees Celsius) is not within the range of the second threshold Tb, it is 0°C< If Tb<17°C, the processor 40 controls the fan 16 of the air cleaning device 10 to stop working.

Please refer to FIG. 6 , in some embodiments, the dew point temperature T4 of the indoor air in step S40 is obtained through the following steps:

S42, collecting indoor air temperature T2 and indoor air humidity RH2; and

S44. Determine the dew point temperature T4 of the indoor air corresponding to the indoor air temperature T2 and the indoor air humidity RH2 according to the relationship data of the pre-stored air temperature, the pre-stored air humidity and the pre-stored dew point temperature.

In this way, the dew point temperature T4 of the indoor air can be obtained quickly.

Specifically, please refer to FIG. 3 again. The air conditioner 100 includes an indoor temperature sensor 70 and an indoor humidity sensor 80.
