Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

In order to better understand the technical solution, the technical solution will be described in detail with reference to the drawings and the specific embodiments.

The following describes a control method and device of an air conditioner, the air conditioner and an electronic device according to an embodiment of the application with reference to the drawings.

An air conditioner and a control method and apparatus thereof according to an embodiment of the present application are described below with reference to the accompanying drawings.

Referring to fig. 1 to 4, in the present embodiment, as shown in fig. 1 and 2, the air conditioner includes an indoor unit, and the indoor unit 100 includes an indoor heat exchanger 101, a first fan 102, and a second fan 103. The first fan 102 is disposed to face an upper portion of the indoor heat exchanger 101, and the second fan 103 is disposed to face a lower portion of the indoor heat exchanger 101.

A first air outlet 104, a second air outlet 105 and a third air outlet 106 are arranged at the front end of the indoor unit 100; an air inlet 107 is formed at the rear side of the indoor unit 100. The first air outlet 104 is communicated with the air inlet 107 to form a first air duct 108, and the first fan 102 is located in the first air duct 108; the second air outlet 105 is communicated with the air inlet 107 and forms a second air duct 109, and the second fan 103 is positioned in the second air duct 109; the third air outlet 106 is communicated with the air inlet 107 and forms a third air duct 110, and the second fan 103 and the first fan 102 are sequentially arranged in the third air duct 110 along the direction from the air inlet 107 to the third air outlet 106. Optionally, the second air outlet 105 is disposed around the first air outlet 104, as shown in fig. 2, a darker area in fig. 2 is the first air outlet 104, and a relatively lighter area around the first air outlet 104 is the second air outlet 105. Optionally, the first fan 102 is an axial fan, and the second fan 103 is a centrifugal fan.

As shown in fig. 3 and 4, the indoor unit 100 further includes: an air guide mechanism 111 and a top air outlet mechanism 112. The air guide mechanism 111 is positioned at the front ends of the first air outlet 104 and the second air outlet 105, and comprises a horizontal air guide strip 113 and a vertical air guide strip 114; the horizontal air guiding strips 113 can be driven by a first driving motor (not shown) in the air guiding mechanism 11 to swing up and down (i.e., open or close), and the vertical air guiding strips 114 can be driven by a second driving motor (not shown) in the air guiding mechanism 11 to swing left and right (i.e., open or close). The top air-out mechanism 111 is disposed at the top of the indoor unit 100 in a vertically movable manner, wherein when the top air-out mechanism 111 moves upwards to a preset highest position, the third air outlet 106 is completely opened; when the top air-out mechanism 111 moves downward to the predetermined lowest position, the third air outlet 106 is closed.

It should be understood that the first air duct 108, the second air duct 109 and the third air duct 110 may all be independent air ducts, or may be areas where three air ducts overlap with each other, which may be determined according to actual situations, and is not limited herein. In the present embodiment, the first air duct 108, the second air duct 109 and the third air duct 110 are areas where three air ducts overlap each other.

In this embodiment, after air enters the indoor unit 100 from the air inlet 107, a part of the air formed by heat exchange in the indoor heat exchanger 101 flows into the room through the first air duct 108 and the first air outlet 104 under the action of the first fan 102, and another part of the air flows into the room through the second air duct 109 and the second air outlet 105 under the action of the second fan 103. In addition, a part of the air flows into the room through the third air duct 110 and the third air outlet 106 under the action of the second fan 103.

It should be noted that in this embodiment, the shower air mode is to blow air from the top of the indoor unit to the room, so that the blown air can freely sink from the top of the room to the ground, thereby creating a shower type wind feeling effect, and meanwhile, the flow rate of air flowing from the side (such as the front) of the indoor unit to the room is relatively low, so as to avoid the force of air collision and improve the indoor comfort.

Fig. 5 is a flowchart illustrating a control method of an air conditioner according to an embodiment of the present disclosure.

As shown in fig. 5, the control method of the air conditioner includes the steps of:

and S101, receiving a starting instruction of a bathing wind mode in a refrigeration mode, and controlling the air conditioner to operate in the bathing wind mode.

Generally, a user may issue a control command to the air conditioner by using a control terminal (e.g., a remote controller) of the air conditioner, for example, to switch an operation mode of the air conditioner. Therefore, when the air conditioner is in the cooling mode, when the user issues the shower wind mode operation, the air conditioner can receive the starting instruction of the shower wind, and then the air conditioner operates in the shower wind mode.

Furthermore, the first fan, the second fan, the top air outlet mechanism, the horizontal air guide strip and the vertical air guide strip can be controlled according to the opening instruction so as to enter the bath air mode to operate.

It should be noted that, in this application, receiving the opening instruction of shower wind mode, it is higher to explain current indoor temperature, can be through controlling first fan, second fan, top air-out mechanism, horizontal wind guide strip, perpendicular wind guide strip this moment, makes the air conditioner get into the shower wind mode to also can guarantee the cooling effect when guaranteeing indoor travelling comfort.

Optionally, the vertical air guide strip can be controlled to be opened to a first opening angle so as to reduce the air output quantity in front of the air conditioner, so that the air flowing out of the air conditioner flows to the left and right areas of the air conditioner, and the cooling speed of the left and right areas of the air conditioner is increased. The first opening angle is the maximum opening angle, and the maximum opening angle of the vertical air guide strip is 40-60 degrees.

Optionally, the horizontal air guide strip can be controlled to be opened to a second opening angle, so that blown air can freely settle towards the ground from the space position of the upper part in a room, a shower type wind sensing effect is created, meanwhile, the air is prevented from impacting force from the front, and indoor comfort is improved. Wherein the second opening angles are all maximum opening angles, and the maximum opening angles of the horizontal air guide strips are all 40-60 degrees.

In the air-conditioning cooling mode, the shower air mode is a mode in which air is blown upward into the room from the ceiling position of the indoor unit so that the blown air can freely sink toward the floor from the space position above the room, thereby providing a shower-like air feeling effect. Therefore, in order to achieve a better cooling effect of the bath air, the horizontal air guide strips are generally inclined upwards, that is, the horizontal air guide strips can be opened upwards by a certain angle, so that the blown cold air can freely sink from the space position at the upper part of the room to the ground. Optionally, if the first fan is an axial flow fan and the second fan is a centrifugal fan, the air of the centrifugal fan should be uniformly discharged from the periphery of the air outlet of the axial flow fan, and the vertical air guide strip may be opened at a certain angle to the left or the right. However, since the wind of the centrifugal fan is blown out by the clockwise operation of the centrifugal wind wheel, the wind of the centrifugal fan generates a small component to the right and is directed obliquely upwards. That is to say, centrifugal fan's right side air output can be great, and the indoor temperature cooling rate that will make perpendicular wind-guiding strip right side like this is very fast. From this, in this application, after receiving the opening instruction, can control perpendicular wind-guiding strip and to the left rotation for indoor temperature can evenly reduce.

Optionally, the top air outlet mechanism may be controlled to ascend to a first height, so that a part of the air of the centrifugal fan is blown out from the top air outlet machine, that is, the air is discharged from the highest air outlet height, and an effect of uniform and slow settlement of cool air is achieved; the other part of the air of the centrifugal fan is blown upwards in the front side and collides with the air of the rotary diffusion axial flow fan to mix, so that the speed reduction and flow dispersion are realized, the air force from the front side is avoided, and the indoor comfort is improved. Wherein the first height is the highest position. Therefore, the top air outlet mechanism is controlled to ascend to the first height, blown air can freely subside towards the bottom of the ground direction from the position of the space above the indoor space, which is relatively high, so that a shower type wind sensation effect is created, and meanwhile, the flow speed of the air flowing into the indoor space from the side part (such as the front side) of the indoor unit is relatively low, so that the air impact strength is avoided, and the indoor comfort is improved.

Alternatively, the first fan may be controlled to operate at a first rotational speed and the second fan may be controlled to operate at a second rotational speed. The range of the first rotating speed is 500 r/min-1000 r/min; the second rotating speed ranges from 200r/min to 450 r/min. Wherein, first rotational speed and second rotational speed can be the maximum rotational speed, and when control first fan and second fan all with the maximum rotational speed operation, can make the air output of air conditioner reach the biggest to make indoor temperature can reduce fast.

S102, acquiring the outdoor environment temperature.

S103, determining a target frequency limiting value of the compressor according to the outdoor environment temperature.

It should be noted that, in order to match the outdoor environment with the operating frequency of the compressor, further reduce the rate of reducing the indoor temperature, and achieve the effect of saving energy, a temperature sensor is disposed outdoors, and the temperature sensor can be used to obtain the current outdoor environment temperature. Or acquiring weather information through a wireless network to acquire the outdoor environment temperature.

After the outdoor environment temperature is obtained, the target frequency limiting value of the compressor matched with the outdoor environment temperature can be determined according to the obtained outdoor environment temperature, and the compressor is controlled to operate according to the target frequency limiting value.

Alternatively, the frequency limit of the compressor may be determined by querying a preset mapping table between the outdoor environment temperature and the frequency limit of the compressor by using the outdoor environment temperature. For example, the preset mapping relationship between the outdoor environment temperature and the frequency limit of the compressor is as follows: when the outdoor environment temperature is A, the frequency limit value is A1, and when the outdoor environment temperature is B, the frequency limit value is B1; then when the obtained outdoor ambient temperature is B, the frequency limit value may be determined to be B1.

It should be noted that different outdoor ambient temperatures should correspond to different target frequency limiting values, however, when one outdoor ambient temperature matches one target frequency limiting value, frequent fluctuation of the target frequency limiting value is inevitably caused, and thus the air conditioner cannot stably operate. Therefore, in order to ensure stable operation of the air conditioner and improve control efficiency, the outdoor ambient temperature may be divided into a plurality of sections in advance, and after a target section where the outdoor ambient temperature is located is determined, a target frequency limit value of the compressor may be determined according to the target section. At this time, the outdoor ambient temperatures in the same temperature interval correspond to the same target frequency limit value.

As a possible implementation manner, in the process of obtaining the target frequency limiting value according to the outdoor environment temperature, as shown in fig. 6, the method includes the following steps:

s201, acquiring a target interval where the outdoor environment temperature is located.

It should be noted that before attempting to acquire the target interval in which the outdoor ambient temperature is located, a different target interval may be set in advance. The range of the target interval and the number of the target intervals can be set according to actual conditions. For example, the number of target sections may be four, or three, or the like.

Further, the acquired outdoor environment temperature is compared with a plurality of target intervals, and then the target interval in which the outdoor environment temperature falls is determined.

S202, determining a first target frequency limiting value of the compressor as a target frequency limiting value according to the target interval.

It should be noted that, in the present application, a mapping relationship between the target interval and the first target frequency limiting value is preset, and after the target interval is obtained, the first target frequency limiting value corresponding to the target interval may be obtained according to the mapping relationship. For example, the preset mapping relationship between the target interval and the target frequency limit value of the compressor is as follows: when the target interval is a first target interval, the target frequency limit value is A1, and when the target interval is a second target interval, the target frequency limit value is B1; then when the obtained target interval is the second target interval, the target frequency limit value may be determined to be B1.

In order to ensure the reliability of the frequency limiting value and improve the cooling effect, the maximum frequency limiting value of the compressor can be corrected to obtain the first target frequency limiting value.

Optionally, according to the target interval, a maximum frequency limit value and a first frequency correction value which are matched with the outdoor environment are obtained, and according to the maximum frequency limit value and the first frequency correction value, a first target frequency limit value is obtained and used as a target frequency limit value of the compressor. For example, the first target frequency limit value is obtained by subtracting the first frequency correction value from the maximum frequency limit value, and the first target frequency limit value is set as the target frequency limit value of the compressor.

For example, six different temperature intervals as shown in table 1, specifically as shown in table 1, may be preset for the outdoor ambient temperature.

Further, table 1 also includes a temperature interval, a maximum frequency limit value corresponding to the temperature interval, a first frequency correction value, and a first target frequency limit value.

TABLE 1

Where T4 is the outdoor environment temperature, fmax (T4) is the maximum frequency limit value matching the outdoor environment, B is the first frequency correction value, and fmax1 is the first target frequency limit value. Alternatively, a mapping relationship of fmax1 ═ fmax (T4) -B is set, fmax (T4) and B can be obtained by looking up table 1 after the outdoor ambient temperature is obtained, and the first target frequency limit can be obtained according to the above formula. Alternatively, fmax1 may be obtained by directly consulting table 1.

For example, when the outdoor ambient temperature T is 35 ℃, the lookup table 1 obtains that the temperature is in the third temperature interval, and further obtains that the maximum frequency limiting value fmax (T) is 71HZ, and the first frequency correction value B is 20, at this time, the first target frequency limiting value fmax 1-71 HZ-20-51 HZ may be obtained according to the above formula, where 51HZ is the target frequency limiting value of the compressor.

Further, when controlling the frequency-limited operation of the compressor, in order to ensure the cooling effect, the target frequency-limited value of the compressor may be determined by comprehensively considering the outdoor ambient temperature and the indoor temperature.

As a possible implementation manner, a target frequency limit value of the compressor is obtained according to the indoor temperature and the outdoor ambient temperature, and in a specific process, as shown in fig. 7:

s301, acquiring indoor temperature and outdoor environment temperature.

Alternatively, a temperature sensor is provided indoors, and the current indoor temperature can be acquired by using the temperature sensor. A temperature sensor is also arranged outdoors, and the current outdoor environment temperature can be acquired by the temperature sensor. The indoor temperature can be obtained after the air conditioner runs in the bathing air mode for a preset time.

S302, a target interval where the outdoor environment temperature is located is obtained, and according to the target interval, the maximum limit frequency value and the first frequency correction value of the compressor are determined.

S303, correcting the highest frequency limiting value by using the first frequency correction value to obtain a first target frequency limiting value.

For specific descriptions of S302 to S303, reference may be made to the descriptions of relevant parts in the above embodiments, and details are not described herein again.

And S304, correcting the first frequency correction value according to the indoor temperature and the set temperature of the air conditioner to obtain a second frequency correction value.

Further, the set temperature of the air conditioner is obtained, and a second frequency correction value for correcting the first target frequency limiting value is determined according to the temperature difference between the indoor temperature and the set temperature. Specifically, the different temperature differences correspond to different correction coefficients, and after the correction coefficients are obtained, a second frequency correction value is obtained according to the correction coefficients and the first frequency correction value, for example, the second frequency correction value is obtained by multiplying the correction coefficients by the first frequency correction value.

Continuing with table 1 as an example, when the current indoor temperature is 27.5 ℃, the set temperature is 26 ℃, and the temperature difference is greater than 1 ℃ and less than 2 ℃, the correction coefficient may be determined to be 1/2, and when the outdoor ambient temperature is 31 ℃, the determined first frequency correction value is 20, and the correction coefficient 1/2 is multiplied by the first frequency correction value 20, so as to obtain the second frequency correction value 10.

And when the current indoor temperature is 29 ℃ and the set temperature is 26 ℃, the temperature difference is 3 ℃ and is more than 2 ℃, the correction coefficient can be determined to be 1/4, and at this time, if the outdoor environment temperature is 31 ℃, the determined first frequency correction value is 20, the correction coefficient 1/4 is multiplied by the first frequency correction value 20, and the second frequency correction value 5 can be obtained.

305. And correcting the highest frequency limit value by using the second frequency correction value to obtain a second target frequency limit value.

Optionally, the maximum frequency limit value is subtracted from the second frequency correction value to obtain a second target frequency limit value.

Continuing with table 1 as an example, the present application is preset with a mapping relationship of fmax2 ═ fmax (T4) -kB, where fmax2 is the second target limiting frequency, and k is a correction coefficient. After the outdoor environment temperature is obtained, fmax (T4) and B can be obtained by looking up table 1, and then a correction coefficient is obtained according to the temperature difference between the indoor temperature and the set temperature, and further a second frequency correction value is obtained. The first target frequency limiting value and the second target frequency limiting value can be obtained according to the mapping relation of fmax1, fmax (T4) -B and fmax2, fmax (T4) -kB.

306. And comparing the first target frequency limiting value with the second target frequency limiting value, and determining the maximum frequency limiting value as a target frequency limiting value.

Optionally, in order to meet the indoor and outdoor requirements, the first target frequency limiting value and the second target frequency limiting value may be compared, and a maximum frequency limiting value may be determined as the target frequency limiting value, so as to ensure that the compressor can operate normally.

To sum up, the technical solution in the embodiment of the present application at least has the following technical effects or advantages:

1. when the air conditioner operates in a refrigeration mode, after an instruction of opening a bath wind mode is received, the air conditioner can be controlled by the first fan, the second fan, the top air outlet mechanism, the horizontal air guide strip and the vertical air guide strip, so that the air conditioner is controlled to enter the bath wind mode to operate by the working state of the first fan, the second fan, the top air outlet mechanism, the horizontal air guide strip and the vertical air guide strip, and the air conditioner can be matched with the bath wind mode to create a comfortable and natural bath type wind field state 3. Further, under the shower wind model, the operating frequency of compressor in the air conditioner needs to be restricted to the air-out temperature to the air conditioner limits, prevents that the air-out temperature from crossing lowly, and cold wind sinks at the excessive speed, can not send far, can realize more even refrigeration effect, further reduces the speed that the indoor temperature reduced, has not only promoted indoor travelling comfort, also can guarantee indoor cooling effect simultaneously.
