S220, under the condition that the natural gas concentration is larger than the normal concentration and smaller than the warning concentration, the air conditioner adjusts the opening degree of a gas stove switch valve according to the natural gas concentration, and adjusts the rotating speed of the fresh air fan.
By adopting the method for controlling the kitchen air conditioner, which is provided by the embodiment of the disclosure, the concentration of the natural gas in the kitchen is detected, and whether the concentration of the natural gas is in a safe range is determined. In the case where the natural gas concentration is greater than the normal concentration and less than the warning concentration, a problem of natural gas leakage occurs in the kitchen, but is in a safe range without affecting cooking. According to the natural gas concentration, the opening degree of the gas stove switch valve is adjusted, and the rising speed of the natural gas concentration is reduced. According to the natural gas concentration, the rotating speed of the fresh air fan is adjusted, and the natural gas concentration or the rising speed of the natural gas concentration is reduced. Through controlling gas-cooker switch valve and new trend fan, discharge natural gas when reducing natural gas leakage volume to reduce natural gas concentration or the speed that concentration risen improves the security of culinary art.
As shown in conjunction with fig. 2, an embodiment of the present disclosure provides another method for kitchen air conditioner control, comprising:
s210, the air conditioner detects the natural gas concentration in the kitchen.
S221, under the condition that the natural gas concentration is larger than the normal concentration and smaller than the warning concentration, the air conditioner obtains the initial opening degree of the gas stove switch valve.
S222, the air conditioner determines the target opening of the gas stove switch valve according to the natural gas concentration and the initial opening.
S223, the air conditioner adjusts the opening of the gas range switch valve to a target opening.
S224, the air conditioner determines the target rotating speed of the fresh air fan according to the natural gas concentration.
S225, the air conditioner adjusts the rotating speed of the fresh air fan to be the target rotating speed.
Wherein, the initial opening degree is the opening degree of the switch valve when a user opens the gas stove.
By adopting the method for controlling the kitchen air conditioner, which is provided by the embodiment of the invention, the target opening degree of the gas stove switch valve is determined according to the natural gas concentration and the initial opening degree, so that the speed of rising the natural gas concentration can be reduced while the influence on cooking is reduced. According to the natural gas concentration, the target rotating speed of the fresh air fan is determined, so that the electric energy is saved, and the natural gas concentration or the rising speed of the natural gas concentration can be reduced. Because the natural gas concentration is continuously changed, the opening of the gas stove switch valve and the rotating speed of the fresh air fan are simultaneously adjusted, and the natural gas concentration or the rising speed of the natural gas concentration is reduced so as to increase the cooking safety.
Optionally, the determining, by the air conditioner in step S222, the target opening of the gas stove switch valve according to the natural gas concentration and the initial opening includes: in the case where the natural gas concentration is greater than the normal concentration and less than the first concentration threshold, the air conditioner determines a difference between the initial opening and the first set opening as the target opening. In the case where the natural gas concentration is greater than or equal to the first concentration threshold value and less than the second concentration threshold value, the air conditioner determines the difference between the initial opening degree and the second set opening degree as the target opening degree. In the case where the natural gas concentration is greater than or equal to the second concentration threshold value and less than the warning concentration, the air conditioner determines the difference between the initial opening degree and the third set opening degree as the target opening degree. Wherein the first set opening is smaller than the second set opening, and the second set opening is smaller than the third set opening. Thus, when the concentration is low, the opening degree of the gas range switching valve is large. In the case of the concentration, the opening degree of the gas range switch valve. When the concentration is high, the opening degree of the gas stove switch valve is small. The smaller the opening of the gas range switch valve, the slower the natural gas leakage speed. The opening degree of the gas stove switch valve is adjusted under different natural gas concentrations, so that the opening degree of the gas stove switch valve corresponds to the natural gas concentration. The opening degree of the switch valve of different gas cookers reduces the rising speed of the natural gas concentration while having little influence on the cooking process.
For the natural gas concentration, the normal concentration value is 1%, the first concentration threshold value is 2%, the second concentration threshold value is 3%, and the warning concentration value is 4%.
Optionally, the value range of the first set opening is [8, 12] percent of the total opening, and preferably, the value of the first set opening is 9%, 10% or 11% of the total opening. The value range of the second set opening is [18, 22] percent of the total opening, and preferably the value of the second set opening is 19%, 20% or 21% of the total opening. The third set opening is set to a value in the range of [28, 32] of the total opening, and preferably the third set opening is set to a value of 29%, 30% or 31% of the total opening. In this way, the values of the first set opening, the second set opening and the third set opening are reduced, so that the natural gas concentration rising speed is reduced while the influence on cooking is small.
Optionally, the determining, by the air conditioner in step S224, the target rotation speed of the fresh air fan according to the natural gas concentration includes: in the case where the natural gas concentration is greater than the normal concentration and less than the first concentration threshold, the air conditioner determines the first set rotational speed as the target rotational speed. The air conditioner determines the second set rotational speed as the target rotational speed in a case where the natural gas concentration is greater than or equal to the first concentration threshold value and less than the second concentration threshold value. The air conditioner determines the third set rotational speed as the target rotational speed in the case where the natural gas concentration is greater than or equal to the second concentration threshold value and less than the warning concentration. The first set rotating speed is smaller than the second set rotating speed, and the second set rotating speed is smaller than the third set rotating speed. Thus, the fresh air fan operates at a low rotational speed under the condition of low concentration. In the case of a medium concentration, the fresh air fan is operated at medium speed. Under the condition of high concentration, the fresh air fan operates at a high rotating speed. The rotating speed of the fresh air fan is adjusted under different natural gas concentrations, so that the rotating speed of the fresh air fan corresponds to the natural gas concentration. The rotating speeds of the different fresh air fans enable the natural gas concentration or the rising speed of the natural gas concentration to be reduced while the electric energy is saved.
Optionally, the first set rotational speed is in a range of [500, 700] rpm, preferably the first set rotational speed is 550rpm, 600rpm or 650rpm. The second set rotational speed is in the range of [800, 1000] rpm, preferably the second set rotational speed is 850rpm, 900rpm or 950rpm. The third set rotational speed is in the range of [1100, 1300] rpm, and preferably the third set rotational speed is 1150rpm, 1200rpm or 1250rpm. Of course, for fresh air fans with different rated rotational speeds, the first set rotational speed, the second set rotational speed and the third set rotational speed may be determined according to the percentage of the rated rotational speed. For example, the first set rotational speed may be 30% of the rated rotational speed. The second set rotational speed may be 60% of the nominal rotational speed. The third set rotational speed may be 90% of the nominal rotational speed. Therefore, the values of the first set rotating speed, the second set rotating speed and the third set rotating speed enable the natural gas concentration or the rising speed of the natural gas concentration to be reduced while the electric energy is saved.
Optionally, the determining, by the air conditioner in step S222, the target opening of the gas stove switch valve according to the natural gas concentration and the initial opening includes:wherein Y is n For the target opening degree, Y 0 For the initial opening degree +>Is natural gas concentration>At normal concentration, alpha is the first conversion coefficient, Y m Is the total opening. The variables in the formula represent only numerical values and do not contain units. For the first conversion coefficient α, it can be adjusted according to the test to a number between (5, 15). For example, α may be 7, 10 or 13. Thus, the target opening degree of the gas stove switch valve can be linearly adjusted, the influence on the cooking effect is reduced, and the rising speed of the natural gas concentration is reduced.
Optionally, the determining, by the air conditioner in S224, the target rotation speed of the fresh air fan according to the natural gas concentration includes:wherein N is n For the target rotational speed +.>Is natural gas concentration>For normal concentration, β is the second conversion factor. The variables in the formula represent only numerical values and do not contain units. The second conversion coefficient β can be adjusted according to the test to a number between (30000, 50000). For example, β may be 36000, 40000, or 44000. Therefore, the target rotating speed of the fresh air fan can be linearly regulated, the consumption of electric energy is reduced, and the concentration of natural gas or the rising speed of the concentration of the natural gas is reduced.
Optionally, the air conditioner in step S220 adjusts the opening of the gas stove switch valve according to the natural gas concentration, and adjusts the rotation speed of the fresh air fan, including: the air conditioner keeps the opening degree of the gas stove switch valve unchanged. The air conditioner adjusts the rotating speed of the fresh air fan to be the rated rotating speed. In case that the stabilization time passes, the air conditioner again detects the natural gas concentration in the kitchen. Under the condition that the natural gas concentration is unchanged, the air conditioner keeps the opening degree of a gas stove switch valve and the rotating speed of the fresh air fan unchanged. Under the condition that the natural gas concentration is reduced, the opening degree of the gas stove switch valve is kept unchanged by the air conditioner. The air conditioner reduces the rotating speed of the fresh air fan. When the natural gas concentration increases, the air conditioner reduces the opening of the gas stove switch valve. The air conditioner keeps the rotation speed of the fresh air fan unchanged. Therefore, the rotating speed of the fresh air fan is adjusted first, the opening degree of the gas stove switch valve is kept unchanged, and the natural gas concentration or the rising speed of the natural gas concentration can be reduced while the cooking effect is not affected. After the stabilization time, if the natural gas concentration is unchanged, the current rotating speed of the fresh air fan is indicated to enable the leakage amount and the discharge amount of the natural gas to be the same. At the moment, the natural gas concentration does not continuously rise, the explosion risk does not exist, and the opening degree of the gas stove switch valve is not adjusted to ensure the cooking effect. If the natural gas concentration is reduced, the current rotating speed of the fresh air fan is indicated to enable the leakage amount of the natural gas to be smaller than the discharge amount. At this time, the natural gas concentration is reduced, so that the danger of explosion does not exist, and the opening degree of the gas stove switch valve is not adjusted to ensure the cooking effect. Simultaneously, the rotation speed of the fresh air fan is regulated down, so that the effect of saving electric energy can be achieved. If the concentration of the natural gas rises, the rotating speed of the current fresh air fan is indicated to enable the leakage amount of the natural gas to be larger than the discharge amount.
