FIG. 1 is a schematic diagram of an application scenario provided by the embodiment of the present application. With reference to FIG. 1 , the application scenario of the embodiment of the present application is introduced.

The ambient temperature in the kitchen changes with the cooking time, cooking type, etc. If one burner of the stove is in working state, the temperature in the kitchen rises slowly; when the two burners of the gas stove work at the same time, the temperature in the kitchen rises faster; Hot air makes it easier to increase the temperature in the kitchen; for example, compared to cold winter, cooking in the kitchen in hot summer requires the air conditioner to be adjusted to a lower temperature so that the human body can feel comfortable. In the related art, the air conditioner in the kitchen operates according to the working mode selected by the user to adjust the temperature in the kitchen, resulting in poor control accuracy and flexibility of the air conditioner.

The technical solutions shown in this application will be described in detail below through specific embodiments. It should be noted that the following embodiments may exist independently or may be combined with each other, and the same or similar content will not be repeatedly described in different embodiments.

First of all, it should be noted that the execution subject of the control method for the kitchen air conditioner provided in the embodiment of the present application may be the kitchen air conditioner, or an electronic device capable of controlling the kitchen air conditioner, such as a server or a mobile terminal. The following embodiments take the kitchen air conditioner as an example to illustrate the control method of the kitchen air conditioner provided in the embodiment of the present application.

Fig. 2 is a schematic flowchart of a control method for a kitchen air conditioner provided in an embodiment of the present application. See Figure 2, the method can include:

S201. Acquire status information of a range hood in a space where the kitchen air conditioner is located, and an ambient temperature where the kitchen air conditioner is located.

The space where the kitchen air conditioner is located is not limited to a family kitchen, but can also be a restaurant kitchen and the like. Wherein, the state information is used to represent whether the range hood is in a working state. The state information may include a state signal of the range hood, and the state signal may be an activation signal, indicating that the range hood is in a working state; the state signal may be a shutdown signal, indicating that the range hood is in an off state. The status information may also include the identification of the range hood, which indicates the installation position of the range hood or the installation direction relative to the kitchen air conditioner, so that the kitchen air conditioner can control the air outlet direction of its air outlet according to the range hood with different identifications.

Optionally, the state information of the range hood may also include the operating mode of the range hood, for example, low wind mode, medium wind mode and high wind mode, and different operating modes correspond to different cooling capacities of the kitchen air conditioner.

If the state information indicates that all range hoods in the space where the kitchen air conditioner is located are not in working state, then the kitchen air conditioner is in an off state. If the state information indicates that the range hood in the space where the kitchen air conditioner is located is in the working state, it can be that one range hood is in the working state, or two or three range hoods are in the working state, then perform the following steps S202.

In the embodiment of the present application, the kitchen air conditioner is communicatively connected with the range hood in the space where it is located, for example, a Bluetooth connection, a WiFi connection, and the like. After the range hood is started, the range hood sends a start signal to the kitchen air conditioner; the kitchen air conditioner starts cooling after receiving the start signal. Of course, the kitchen air conditioner can continuously acquire the status information of the range hood, and when the status information includes a start signal, it means that the range hood is in a working state, and the cooling is started.

There are many ways to obtain the ambient temperature of the kitchen air conditioner. For example, an intelligent temperature sensor is installed in the kitchen, which communicates with the kitchen air conditioner to obtain the ambient temperature of the kitchen air conditioner; It can be installed in the outdoor unit of the kitchen air conditioner, and the temperature sensor can also be installed in the indoor unit and the outdoor unit of the kitchen air conditioner at the same time. Of course, multiple temperature sensors can also be provided, and the average temperature can be calculated through a mathematical algorithm to improve the accuracy of temperature detection.

S202. If the state information indicates that there is a working range hood in the space, adjust a target parameter of the kitchen air conditioner according to the ambient temperature, where the target parameter is related to the cooling capacity of the kitchen air conditioner.

This step can be understood as, when a range hood is turned on in the space where the kitchen air conditioner is located, one or more range hoods are turned on, and then the target parameters of the kitchen air conditioner are adjusted according to the ambient temperature, The kitchen air conditioner is cooled, thereby reducing the temperature of the space where the kitchen air conditioner is located.

The kitchen air conditioner in the embodiment of the present application includes an indoor fan and an outdoor compressor, wherein the target parameter may only include the frequency of the compressor, or the target parameter may only include the speed of the indoor fan. Of course, the target parameter may also include the compressor frequency and the speed of the indoor fan. Generally, as the frequency of the compressor increases, the cooling capacity of the kitchen air conditioner increases; when the speed of the indoor fan increases, the cooling capacity of the kitchen air conditioner increases.

Of course, the target parameters related to the cooling capacity of the kitchen air conditioner are not limited to the frequency of the compressor and the rotation speed of the indoor unit, and the target parameters may also include the rotation speed of the outdoor fan.

In this way, the frequency of the compressor of the kitchen air conditioner and/or the rotational speed of the indoor unit is adjusted according to the ambient temperature to adjust the cooling capacity of the kitchen air conditioner, thereby adjusting the temperature of the space where the kitchen air conditioner is located.

FIG. 3 is a schematic diagram of a kitchen air-conditioning cooling scenario provided by an embodiment of the present application. With reference to FIG. 3 , the cooling scene of the above-mentioned kitchen air conditioner will be described.

When the range hood in the kitchen is in the working state, the kitchen air conditioner starts the cooling mode to reduce the temperature in the kitchen; adjusts the target parameters of the kitchen air conditioner according to the ambient temperature, thereby adjusting the cooling capacity of the kitchen air conditioner. In this way, according to the actual situation of the kitchen, the state of the range hood and the ambient temperature, adjusting the cooling capacity of the kitchen air conditioner will help improve the accuracy and flexibility of the kitchen air conditioner control.

It should be noted here that, in the kitchen air conditioner provided in the embodiment of the present application, the lowest end of the air outlet is flush with or higher than the table of the gas stove. The air outlet of the kitchen air conditioner in the embodiment of the present application is equipped with fan blades, and the air outlet angle of the air outlet can be changed by the angle of the air conditioner fan blades. The wind outlet angle can be horizontal, and the wind outlet angle can also blow air obliquely upward, for example, blow air obliquely upward within a range of 20 degrees upward from the horizontal. Such setting can prevent the air outlet from blowing downwards to the burner of the gas stove, thereby affecting the stability of the flame of the burner. In addition, the wind blowing horizontally or obliquely can face the cooker's upper body, which can quickly reduce the temperature of the cooker's surrounding area.

The control method of the kitchen air conditioner provided in the embodiment of the present application obtains the state information of the range hood in the space where the kitchen air conditioner is located, and the ambient temperature where the kitchen air conditioner is located. When the state information indicates that there is a range hood in a working state in the space, then Adjust the target parameters of the kitchen air conditioner according to the ambient temperature, thereby adjusting the cooling capacity of the kitchen air conditioner, and reduce the temperature of the kitchen air conditioner to varying degrees. In this way, the temperature in the space is adjusted according to the state information of the range hood in the space where the kitchen air conditioner is located and the ambient temperature. It is beneficial to improve the accuracy and flexibility of kitchen air conditioning control.

Fig. 4 is a schematic flowchart of another control method for a kitchen air conditioner provided in an embodiment of the present application. Please combine with Figure 4, the method may include:

S401. Acquire status information of a range hood in a space where the kitchen air conditioner is located, and an ambient temperature where the kitchen air conditioner is located.

It should be noted that, the execution process of step S401 may refer to the execution process of S201, which will not be repeated here.

S402. Determine whether there is a working range hood in the space.

This step determines the state of the range hood in the space where the kitchen air conditioner is located, and judges whether there is a range hood turned on in the space. If there is a range hood turned on, it indicates that there is cooking, and the space needs to be cooled; if there is no range hood turned on, Then it means that there is no cooking and there is no need to turn on the kitchen air conditioner.

Among them, there may be multiple methods for judging whether there is a range hood in a working state in the space. For example, a signal switch is provided in the range hood, and when the range hood is started, the signal switch is turned on to send a signal, and when the range hood is turned off, the signal switch is turned on without sending a signal. The kitchen air conditioner judges whether the range hood is in working condition by receiving the signal. For another example, the exhaust duct of the range hood is provided with a flow sensor. When the flow sensor detects that the gas flow in the exhaust duct exceeds a preset value, a signal is sent to the kitchen air conditioner so that the kitchen air conditioner can judge that the range hood is in working condition. For another example, a noise sensor is installed in the range hood, and the noise sensor is used to detect the noise of the fan inside the range hood, and the kitchen air conditioner judges the working state of the range hood through the noise value sent by the noise sensor.

When there is no range hood in working state in the space where the kitchen air conditioner is located, that is, when S402 is "No", the process ends, and the kitchen air conditioner is turned off at this time; when there is a range hood in working state in the space where the kitchen air conditioner is located , that is, when S402 is "Yes", the following step S403 is performed.

In this embodiment of the present application, the ambient temperature may include an outdoor ambient temperature of a space where the kitchen air conditioner is located, for example, an outdoor ambient temperature outside the kitchen. Optionally, the outdoor unit of the kitchen air conditioner is provided with a temperature sensor, so as to obtain the outdoor ambient temperature.

S403. Acquire an initial frequency of the compressor according to the outdoor ambient temperature and a preset mapping relationship between the outdoor ambient temperature and compressor frequency; determine an initial rotational speed of the indoor fan according to the outdoor ambient temperature.

The outdoor ambient temperature affects the indoor temperature, and also affects the heat dissipation of the outdoor unit evaporator, which in turn affects the cooling capacity of the kitchen air conditioner. Determining the initial frequency of the compressor according to the outdoor temperature will help improve the accuracy of kitchen air conditioning control. The preset mapping relationship between the outdoor ambient temperature and the frequency of the compressor can be stored in the memory of the kitchen air conditioner.

Exemplarily, the mapping relationship between the preset outdoor ambient temperature and the frequency of the compressor may be shown in Table 1:

Table 1

室外环境温度/℃Outdoor ambient temperature/℃	<22<22	22-3222-32	32-4032-40	40-4840-48	>48>48
压缩机的初始频率/HzCompressor initial frequency/Hz	3535	4545	7070	6060	4040

According to the current outdoor ambient temperature detected by the temperature sensor, query the mapping relationship between the preset outdoor ambient temperature and compressor frequency stored in the memory, so as to determine the initial frequency of the compressor, which is beneficial to the accuracy of kitchen air conditioning control and also It is convenient to adjust the frequency of the subsequent compressor.

It should be noted that the above-mentioned mapping relationship between the outdoor ambient temperature and the compressor frequency can be shown in Table 1, and the mapping relationship between the outdoor ambient temperature and the compressor frequency can also be a mathematical formula. For the initial frequency of the compressor, the embodiment of the present application does not limit the specific mathematical formula and the specific values in the above-mentioned Table 1.

Determine the initial speed of the indoor fan according to the outdoor ambient temperature. Exemplarily, the memory of the kitchen air conditioner stores the mapping relationship between the outdoor ambient temperature and the speed of the indoor fan, and the mapping relationship can be shown in Table 2:

Table 2

室外环境温度/℃Outdoor ambient temperature/℃	<22<22	22-3222-32	32-4032-40	40-4840-48	>48>48
室内风机的转速/rmpIndoor fan speed/rmp	750750	10001000	11001100	12001200	13001300

It should be noted that the above-mentioned mapping relationship between the outdoor ambient temperature and the speed of the indoor fan can be shown in Table 1, and the mapping relationship between the outdoor ambient temperature and the speed of the indoor fan can also be a mathematical formula. The initial speed of the indoor fan, the embodiment of the present application does not limit the specific mathematical formula and the specific numerical values in the above-mentioned Table 1.

Optionally, the initial rotational speed of the above-mentioned indoor fan may also be obtained by receiving a control instruction. Specifically, the kitchen air conditioner receives the control instruction, for example, the remote controller sends the control instruction of the speed mode to the kitchen air conditioner. Exemplarily, the rotation speed of 750rmp corresponds to the silent mode, the rotation speed of 1000rmp corresponds to the low wind mode, the rotation speed of 1100rmp corresponds to the stroke mode, the rotation speed of 1200rmp corresponds to the high wind mode, and the rotation speed of 1300rmp corresponds to the powerful mode. The kitchen air conditioner determines the initial rotational speed of the indoor fan according to the received control instruction.

In the embodiment of the present application, the ambient temperature may also include the indoor ambient temperature of the space where the kitchen air conditioner is located, wherein the indoor ambient temperature is the temperature of the non-cooking area in the space, and the non-cooking area is separated from the range hood by at least a preset distance, The embodiment of the present application does not limit the preset distance. For example, the indoor ambient temperature is the temperature of the indoor air inlet of the kitchen air conditioner, and the indoor ambient temperature is obtained by installing a temperature sensor at the indoor air inlet of the kitchen air conditioner. Of course, a temperature detection device can also be installed in other positions of the non-cooking area to obtain the indoor ambient temperature.

S404. Acquire the frequency correction coefficient of the compressor according to the indoor ambient temperature, and the preset indoor ambient temperature and compressor frequency correction coefficient; according to the indoor ambient temperature, and the preset indoor ambient temperature and The speed correction coefficient of the indoor fan is used to obtain the speed correction coefficient of the indoor fan.

The indoor ambient temperature reflects the temperature of the non-cooking area in the kitchen, which affects the cooling capacity of the kitchen. The compressor frequency correction coefficient is obtained according to the indoor ambient temperature to correct the frequency of the compressor, and the indoor fan speed correction coefficient is obtained according to the indoor ambient temperature to correct the indoor fan speed. Correcting the rotation speed is beneficial to further improving the accuracy of adjusting the cooling capacity of the kitchen air conditioner.

The memory of the kitchen air conditioner can store correction coefficients for indoor ambient temperature and compressor frequency, and correction coefficients for indoor ambient temperature and indoor fan speed; that is, the corrections to compressor frequency and indoor fan speed are different under different indoor ambient temperatures. Exemplarily, the correction coefficients of the indoor ambient temperature and the frequency of the compressor, and the correction coefficients of the indoor ambient temperature and the rotational speed of the indoor fan may be as shown in Table 3.

table 3

According to the current indoor ambient temperature detected by the temperature detection device, query the preset indoor ambient temperature stored in the memory and the correction coefficient of the compressor frequency and the indoor fan speed respectively, and determine the correction coefficient of the compressor frequency and the correction coefficient of the indoor fan speed , and then respectively correct the frequency of the compressor and the rotational speed of the indoor fan to further improve the accuracy of kitchen control.

S405. Multiply the initial frequency by the frequency correction coefficient to obtain the target frequency; multiply the initial rotational speed by the rotational speed correction coefficient to determine the target rotational speed of the indoor fan.

This step can be understood as correcting the initial frequency of the compressor according to the frequency correction coefficient obtained in step S404 to obtain the target frequency; performing correction according to the initial speed of the indoor fan obtained in step S404 to obtain the target speed; so that the kitchen The air conditioner can operate according to the target frequency and target speed, so that the cooling capacity of the kitchen air conditioner matches the space where the kitchen air conditioner is located, and improves the cooling accuracy of the kitchen air conditioner.

There may be one range hood in the space where the kitchen air conditioner is located, such as a family kitchen; there may be multiple range hoods in the space where the kitchen air conditioner is located, such as a restaurant kitchen. The number of working range hoods in the space where the kitchen air conditioner is located affects the temperature of the space, which in turn affects the cooling capacity of the kitchen air conditioner.

S406. According to the state information, determine the number of range hoods in the working state in the space.

The status information may include the total number of range hoods in the space, the number of range hoods in the working state, and the number of range hoods in the non-working state. The kitchen air conditioner directly determines the number of range hoods in the working state in the space according to the status information. Alternatively, a counter is provided in the kitchen air conditioner to count the number of starting signals in the received status information, so as to determine the number of range hoods in the working state in the space.

S407. Correct the target frequency according to the quantity.

Wherein, the corrected target frequency is positively correlated with the number, and the corrected target frequency increases as the number of range hoods in working state increases, that is to say, the number of range hoods in working state increases, the Increased cooling capacity. Exemplarily, when one range hood is started, the target frequency is multiplied by a correction factor of 1.1, so that the compressor operates at a 10% higher target frequency; when two range hoods are started, the target frequency is multiplied by a correction factor of 1.2, so that the compressor Run according to the target frequency increased by 20%. Of course, the method of correcting the target frequency is not limited to this, and the target frequency can also be graded. When the two range hoods are started, the target frequency is increased by one grade, thereby correcting the target frequency.

S408. Control the compressor to run at the target frequency; control the indoor fan to run at the target speed.

Wherein, the compressor is controlled to run according to the target frequency, and the target frequency is the target frequency corrected according to the number of range hoods started. In this way, the target frequency of the compressor comprehensively considers the outdoor ambient temperature, the indoor ambient temperature, and the number of compressors in the working state, so as to improve the accuracy of determining the cooling capacity of the kitchen air conditioner, thereby improving the accuracy of the control of the kitchen air conditioner.

In addition, the indoor fan is controlled to move at a target rotational speed, and the target rotational speed may be the initial rotational speed corrected according to the indoor ambient temperature and the outdoor ambient temperature. Of course, the target rotational speed can also be corrected according to the number of range hoods in working state on this basis.

Specifically, the target speed is corrected according to the number of range hoods in the working state in the space, wherein the corrected target speed is positively correlated with the number, and the corrected target speed increases with the number of the range hoods in the working state. The increase of the number increases, that is to say, the number of range hoods in the working state increases, and the cooling capacity of the kitchen air conditioner increases.

It should be noted here that although in this embodiment the frequency of the compressor of the kitchen air conditioner and the speed of the indoor fan are simultaneously adjusted to adjust the cooling capacity of the kitchen air conditioner, this is not limiting. The embodiment of the present application can also adjust the cooling capacity of the kitchen air conditioner only by adjusting the compressor frequency of the kitchen air conditioner, or the embodiment of the present application can also adjust the cooling capacity of the kitchen air conditioner only by adjusting the speed of the indoor fan of the kitchen air conditioner.

After controlling the compressor to run at the target frequency and the indoor fan to run at the target speed, the process ends.

In the control method of the kitchen air conditioner provided in the embodiment of the present application, the initial frequency of the compressor and the initial rotational speed of the indoor fan are determined according to the outdoor ambient temperature, and the initial frequency and initial rotational speed are corrected according to the indoor ambient temperature and the number of range hoods in operation , to obtain the target frequency and target speed, so that the kitchen air conditioner can control its cooling capacity according to the indoor ambient temperature, outdoor ambient temperature and the number of starts of the range hood, which is conducive to improving the accuracy and flexibility of kitchen control.

In some implementation manners, the kitchen air conditioner is provided with multiple air outlets, and each air outlet corresponds to one range hood. Exemplarily, the kitchen air conditioner is provided with two air outlets juxtaposed on the left and right, and the two air outlets respectively correspond to a range hood.

The control method of the kitchen air conditioner provided in the embodiment of the present application further includes: controlling the kitchen air conditioner to output air from an air outlet corresponding to a range hood in a working state. That is to say, the air outlet corresponding to the range hood in the working state is controlled to output air.

Exemplarily, the air outlet of the kitchen air conditioner is provided with a panel, and the panel is connected to the motor through a transmission mechanism, and the motor is controlled to drive the panel to move to open the air outlet, so that the air outlet can emit air.

Fig. 5 is a schematic diagram of another scenario of controlling cooling of a kitchen air conditioner provided by an embodiment of the present application. Referring to Figure 5, both range hoods are in working condition, and the panel controlling the left air outlet and the right air outlet panel are respectively opened, so that the left air outlet and the right air outlet respectively discharge air. Of course, when one of the range hoods is turned on, only the corresponding air outlet of this range hood will emit air. At this time, the panel of the air outlet on the right side blocks the air outlet on the right side and cannot blow out the air.

Continuing to refer to FIG. 5 , the embodiment of the present application can also control the air outlet grille or air deflector of the left air outlet to adjust the air outlet direction of the left air outlet, and control the forehead air outlet grille or air guide of the right air outlet. Plates etc. adjust the air outlet direction of the air outlet on the right side, so that the cooker who makes the air outlet toward the front side of the stove is given air, so as to quickly reduce the temperature of the cooker's surrounding area.

It should be noted that the two range hoods shown in FIG. 5 are arranged side by side. Of course, this is not restrictive. The two range hoods can also be arranged in an L shape, which is not limited in this embodiment of the present application. The kitchen air conditioner can be installed in the middle of the two range hoods.
