Detailed ways

The embodiments of the present application are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals indicate the same or similar elements or elements with the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary, and are intended to explain the application, but should not be understood as a limitation to the application.

The following describes the air conditioner and its control method and device according to the embodiments of the present application with reference to the drawings.

It should be noted that the inventor of the present application, after studying the technical solutions in related technologies, found that at least the following technical problems exist in related technologies:

The indoor air circulates through the indoor fan to dilute the indoor refrigerant concentration, although it can reduce the indoor concentration and reduce the risk of deflagration. However, because the room is in a relatively closed environment, the concentration of the indoor refrigerant will remain at a fixed value after the indoor fan has been running for a period of time; and the indoor air quality is still poor at this refrigerant concentration.

In addition, the air conditioner in this embodiment is provided with a fresh air system. As shown in Figure 1, the figure is a schematic structural diagram of an air conditioner in an embodiment disclosed in this application, in which a fresh air system 4 is provided at one end of the air conditioner body 3, and an air inlet 1 and an air outlet 2 are provided on the fresh air system ; The air inlet 1 is connected to the outdoor, and the air outlet 2 is connected to the indoor. It should be understood that the air conditioner and the fresh air system can also be set separately, specifically, it can be determined according to the actual situation, which is not limited here.

Example one

Fig. 2 is a schematic flowchart of a control method of an air conditioner in an embodiment disclosed in this application. As shown in FIG. 2, the control method of the air conditioner in the embodiment of the present application specifically includes the following steps:

S21. Obtain a first refrigerant concentration of the indoor refrigerant.

Specifically, the amount of leaked refrigerant can be detected by a sensor in the air conditioner. Then, according to the ratio between the leaked refrigerant amount and the current indoor volume, the first refrigerant concentration of the indoor refrigerant can be determined.

S22. Detect and determine that the concentration of the first refrigerant is greater than the first concentration threshold, and then control the start of the fresh air system, where the fresh air system can be set in the air conditioner, or independently set on the indoor wall, or set in other electrical appliances There is no restriction here.

Specifically, the first refrigerant concentration of the indoor refrigerant is obtained and compared with the first concentration threshold. When it is greater than the first concentration, it indicates that the current indoor refrigerant concentration is too large. At this time, the fresh air system is controlled to start up. Accelerate the indoor and outdoor air circulation, so as to discharge the indoor refrigerant to the outside, reduce the indoor refrigerant concentration, and improve the indoor air quality. Wherein, the first concentration threshold is a preset concentration value.

In summary, in the air conditioner control method provided by the embodiments of the present application, when it is detected that the first refrigerant concentration of the indoor refrigerant is greater than the first concentration threshold, the fresh air system is controlled to start to accelerate the indoor and outdoor air circulation, thereby reducing the indoor The refrigerant is discharged outdoors, reducing the concentration of indoor refrigerant and improving indoor air quality.

It should be noted that when the fresh air system is controlled to start, the motor in the fresh air system can be controlled to rotate forward or backward. Among them, when the motor in the fresh air system rotates in the forward direction, it blows outdoor air to the room; when it rotates in the reverse direction, it blows the indoor air to the outdoors.

As a possible implementation, while or after controlling the reverse rotation of the motor, the outdoor unit in the air conditioner is controlled to be powered off, and/or the indoor fan and/or the air deflector in the air conditioner are controlled to be turned off to reduce the The speed of the refrigerant flowing into the room.

Optionally, after controlling the reverse rotation of the motor in the fresh air system, the concentration of the indoor refrigerant can be detected again. In order to facilitate the distinction, the refrigerant concentration acquired at this time is referred to as the second refrigerant concentration.

Among them, when the motor in the fresh air system reverses for a period of time, if it is detected that the concentration of the second refrigerant is still greater than the first concentration threshold, it indicates that the refrigerant leakage in the air conditioner is relatively large. Due to the limited internal space of the air conditioner, when the leaked refrigerant accumulates in the air conditioner too much, the concentration of the refrigerant in the air conditioner will gradually increase, which may easily lead to the risk of burning the air conditioner. In order to avoid the above situation, control the motor to rotate forward at this time, and control the indoor fan in the air conditioner to turn on, and control the air deflector in the air conditioner to open to the maximum air outlet angle, so that the air conditioner can maximize the accumulation in the air conditioner The refrigerant in the air conditioner is purged to the outside of the air conditioner, thereby reducing the local refrigerant concentration in the air conditioner, and avoiding the leakage of refrigerant from gathering inside the air conditioner.

In addition, if the concentration of the second refrigerant is less than or equal to the first concentration threshold, it indicates that the current air conditioner does not accumulate too much refrigerant. But for safety, you can choose to continue testing the concentration of indoor refrigerant at this time.

As another possible implementation, at the same time or after controlling the motor to rotate forward, the indoor fan in the air conditioner can also be controlled to turn on, and the air deflector in the air conditioner can be controlled to open to introduce outdoor air into the room, thereby increasing Indoor air pressure, under the action of the indoor and outdoor pressure difference, the indoor air will flow from the gap in the room to the outdoors, thereby reducing the concentration of indoor refrigerant and improving indoor air quality.

Further, in order to increase the speed at which outdoor air enters the room, the wind deflector can be controlled to open to the maximum air outlet angle.

On the basis of the foregoing embodiment, the concentration of the indoor refrigerant can also be detected again. In order to facilitate the distinction, the refrigerant concentration acquired at this time is referred to as the third refrigerant concentration.

Among them, when the motor rotates in the forward direction for a period of time, if it is detected that the third refrigerant concentration is less than or equal to the second concentration threshold and greater than the third concentration threshold, the motor and indoor fan are controlled to continue the current operating state, and the air deflector is controlled to swing and send The wind, for example, can control the wind deflector to swing up and down to send air. In this way, it can be avoided that the wind deflector continues to blow at an angle, causing the concentration of refrigerant in a certain area of the room to be too high. In other words, by controlling the air deflector to swing and blow the air, the refrigerant can be evenly diffused to all corners of the room, avoiding the occurrence of excessively high concentrations of the indoor refrigerant. Wherein, the second concentration threshold is less than or equal to the first concentration threshold, and the third concentration threshold is less than or equal to the second concentration threshold.

If it is detected that the third refrigerant concentration is less than or equal to the third concentration threshold, it indicates that the current indoor refrigerant concentration has been reduced to a certain level. At this time, the fresh air system itself can be operated to maintain indoor air quality; that is, this It can control the indoor fan to turn off and keep the motor continuing to rotate in the positive direction. Further, after a period of time, if the concentration of the indoor refrigerant detected again is too high, the corresponding steps can be selected and executed according to the interval of the current concentration.

In addition, if the concentration of the third refrigerant is greater than the second concentration threshold, it indicates that the current concentration of the indoor air refrigerant is still relatively high. Therefore, it is necessary to continue to detect the concentration of the indoor refrigerant.

Further, after the air deflector is controlled to swing and blow air, the concentration of the indoor refrigerant can be continuously detected. In order to facilitate the distinction, the refrigerant concentration acquired at this time is referred to as the fourth refrigerant concentration.

Among them, when the air deflector is controlled to swing and supply air for a period of time, if it is detected that the fourth refrigerant concentration is less than or equal to the third concentration threshold, it indicates that the current indoor refrigerant concentration has been reduced to a certain level. At this time, only the fresh air system itself is required to operate , The indoor air quality can be maintained; that is to say, the indoor fan can be controlled to turn off at this time, and the motor can continue to rotate forward. Further, after a period of time, if the concentration of the indoor refrigerant detected again is too high, the corresponding steps can be selected and executed according to the interval of the current concentration.

In addition, if the concentration of the fourth refrigerant is greater than the third concentration threshold, it is necessary to continue to detect the concentration of the indoor refrigerant.

It should be understood that in this application, the second refrigerant concentration, the third refrigerant concentration, and the fourth refrigerant concentration are re-detected after an interval of time.

FIG. 5 is a schematic diagram of the effect comparison between the control method of the air conditioner according to an embodiment of the present application and the method in the related art. As shown in FIG. 5, the curve a in the figure is the effect diagram of the method provided by the embodiment of the application, and the curve b is the effect diagram of the method in the related art. Among them, in the related art method, when the indoor refrigerant concentration reaches P0, only the indoor fan is turned on to promote indoor and outdoor air circulation. The method in this application controls the motor in the fresh air system to reverse when the indoor refrigerant concentration reaches P0. It can be seen from the figure that from T1 to T2, the slope of curve a is greater than the slope of curve b. This is because in this application, when the fresh air system motor reverses, the indoor air is forced to be extracted to the outdoors; while the indoor fan is turned on in the related art , In order to increase the pressure of the indoor air, thereby speeding up the indoor air to be left from the gap between the doors and windows; therefore, the method in this application can quickly reduce the concentration of the indoor refrigerant.

It should be noted that in this application, the first concentration threshold, the second concentration threshold, and the third concentration threshold may all be interval range values, or all may be a fixed value. Among them, the first concentration threshold in this application is 20%-35%, preferably 25%; the second concentration threshold is 15%-25%, preferably 15%; and the third concentration threshold is 5%-15%, preferably 5%.
