Detailed Description
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
Fig. 1 is a schematic flowchart of a control method of an air conditioner in an embodiment of the present invention. The method of fig. 1 may be applied to an air conditioner, the method including:
s102, acquiring the ambient temperature and the target object temperature.
The ambient temperature may be an indoor ambient temperature and/or an outdoor ambient temperature, the target object temperature may be an object conforming to a preset category, such as a human body, an animal body, or the like, and the target object temperature may be a temperature of a certain target object or temperatures of a plurality of target objects.
And S104, judging whether the environment temperature and the target object temperature meet high temperature conditions.
It is considered that, in the case where the ambient temperature is high and the temperature of the target object is high, if the cooling rate of the air conditioner is too high and the target object cannot adapt to the rapidly decreasing ambient temperature, discomfort or even an air conditioning disease is likely to occur, whereas in the case where the ambient temperature is low or the temperature of the target object is low, the above phenomenon is unlikely to occur. Therefore, it is necessary to first determine the ambient temperature and the target object temperature, and execute the subsequent steps only when the ambient temperature and the target object temperature satisfy the high temperature condition.
And S106, if the high temperature condition is met, judging whether the air conditioner operates in a low temperature state.
The set temperature difference corresponding to the low temperature state is larger than a first temperature difference threshold value or the outlet air temperature is smaller than a first temperature threshold value or the set temperature is smaller than a second temperature threshold value, and the set temperature difference is the difference between the ambient temperature and the set temperature. The first temperature difference threshold may take any value from 15 ℃ to 25 ℃ and the first temperature threshold may take any value from 13 ℃ to 22 ℃, for example.
Alternatively, it may be determined to operate in a low temperature state when the following conditions are satisfied:
if the set temperature difference is larger than the first temperature difference threshold value, determining that the air conditioner operates in a low-temperature state; or if the outlet air temperature is less than the first temperature threshold, determining that the air conditioner operates in a low-temperature state; or if the set temperature is less than the fourth temperature threshold, determining that the air conditioner operates in a low-temperature state. By the high-temperature condition judgment and the low-temperature state judgment, the pertinence of the staged cooling function can be improved, and the false execution can be avoided.
When the air conditioner operates in a low-temperature state, the current set temperature is far lower than the ambient temperature, the outlet air temperature is too low, or the set temperature is too low, which all causes the refrigeration speed of the air conditioner to be too high, causes the ambient temperature to be sharply reduced, and needs to execute a staged cooling control logic.
And S108, if the air conditioner is operated in the low-temperature state, prompting a user whether to enter a healthy air conditioning mode, and/or controlling to enter the healthy air conditioning mode.
Wherein the controlling of entering the health air-conditioning mode may include: and controlling the air conditioner to cool down stage by stage according to the temperature of the target object and/or the air outlet temperature. Optionally, the staged cooling may be performed by the target temperature, for example, each time the air conditioner is controlled to cool to reach a target temperature, the target object is kept at the target temperature for a period of time, and then the air conditioner is controlled to cool to a next lower target temperature, and the target object is kept at the target temperature for a period of time, so that the target object is gradually adapted to reduce discomfort and hidden danger; similarly, cooling can also be carried out through the air-out temperature stage by stage, if the air-out temperature is low excessively, then improve the air-out temperature gradually, and every time improve the air-out temperature, all keep a period to make the target object adapt to.
The control method of the air conditioner provided by this embodiment can determine whether the ambient temperature and the target object temperature satisfy the high temperature condition and whether the air conditioner operates in the low temperature state, and if both the conditions are satisfied, can prompt the user whether to enter the healthy air conditioning mode or control to enter the healthy air conditioning mode. By judging the high-temperature condition and the low-temperature state, the pertinence and the accuracy of judging the health air-conditioning mode can be improved, and the error execution is avoided; by executing the mode of entering the healthy air conditioner, the discomfort and the hidden danger caused by the rapid cooling of the air conditioner can be reduced.
As an embodiment, in the case that there is only one target object, the above S104 may be performed according to the following steps:
a1, if there is a target object, determining whether the target object temperature is greater than or equal to the third temperature threshold and the environment temperature is greater than the fourth temperature threshold. Taking the target object as a human body, the second temperature threshold may be any value from 37 ℃ to 40 ℃, and the third temperature threshold may be any value from 39 ℃ to 43 ℃, for example.
Specifically, the ambient temperature may include an indoor ambient temperature and an outdoor ambient temperature, and since the target object is generally indoors, the relationship between the ambient temperature and the temperature threshold value may be judged by the indoor ambient temperature. The step a1 can adopt the following two judgment methods:
1. and if the indoor environment temperature is greater than the fourth temperature threshold, determining that the environment temperature is greater than the fourth temperature threshold.
2. And if the outdoor environment temperature is greater than the fourth temperature threshold value and the difference value between the outdoor environment temperature and the indoor environment temperature is less than the second temperature difference threshold value, determining that the environment temperature is greater than the fourth temperature threshold value.
By judging the relation between the indoor environment temperature and the threshold value or the relation between the difference values of the outdoor environment temperature and the indoor environment temperature and the threshold value, whether the high-temperature condition is met can be accurately judged, and the accuracy of the staged cooling function is improved.
A2, if the target object temperature is greater than or equal to the third temperature threshold and the environment temperature is greater than the fourth temperature threshold, determining that the high temperature condition is satisfied. In the case where the body temperature of the target subject is excessively high and the ambient temperature is also excessively high, it is determined that the high temperature condition is satisfied.
As another embodiment, in the case where there are a plurality of target objects, the above S104 may be performed according to the following steps:
b1, if there are multiple target objects, determining whether the maximum temperature of the multiple target objects is greater than the third temperature threshold and whether the ambient temperature is greater than the fourth temperature threshold. If there are a plurality of target subjects, the body temperature of only a part of the target subjects may be overhigh, while the body temperatures of other target subjects are normal, in this case, the highest temperature among all the target subjects is taken as the standard, and if the highest temperature is greater than the second temperature threshold, the subsequent steps are required to be performed to reduce the adverse effect of the sudden drop of the ambient temperature.
And B2, if the highest temperature is larger than the third temperature threshold and the environment temperature is larger than the fourth temperature threshold, determining that the high temperature condition is met.
The parts of this embodiment that are the same as the above embodiment are not described herein again, and reference may be made to the relevant contents of the above embodiment.
In consideration of the influence of factors such as the ambient temperature (air temperature) and the wind speed on the sensible temperature of the target object, when the step-by-step cooling function (which may also be referred to as a health air conditioning function) is executed, the target object temperature may be set as a reference temperature and then the target temperature or the outlet air temperature may be controlled. As an embodiment, the step S108 may be executed according to the following steps:
and A1, controlling the air conditioner to operate by taking the stage temperature as the target temperature. The stage temperature is less than the target object temperature. Alternatively, the stage temperature may be a difference between the target object temperature and a second preset temperature difference. In this embodiment, a preset temperature difference may be set, for example, the preset temperature difference is set to 2 ℃, and then the first-stage temperature is equal to the target object temperature minus 2 ℃.
A2, when the ambient temperature decreases to the stage temperature, continuing to operate for a first duration and decreasing the stage temperature by a first preset temperature difference. The first predetermined temperature difference may be the same as or different from the second predetermined temperature difference. For example, the second predetermined temperature difference and the first predetermined temperature difference may be the same as the above-mentioned predetermined temperature difference, i.e., 2 ℃, or different predetermined temperature differences. The first time period may be any value from 3min to 8min, for example.
And A3, circularly executing the steps until the stage temperature is equal to or less than the set temperature, and controlling the air conditioner to continuously operate with the set temperature as the target temperature. The air conditioner continues to operate with the set temperature as the target temperature, and the current health air conditioning function is quitted.
As another embodiment, the step S108 may be performed as follows:
and B1, controlling the air conditioner to operate at the preset expansion valve opening degree. The preset expansion valve opening is smaller than the current expansion valve opening. Alternatively, the preset expansion valve opening degree may be a difference value between the current expansion valve opening degree and the second preset opening degree. In this embodiment, a preset opening may be set, for example, if the preset opening is set to 5, the preset opening is the current opening minus 5.
B2, when the operation is at the second time length, reducing the preset expansion valve opening by the first preset opening.
Alternatively, the second preset opening degree and the first preset opening degree may be the same preset opening degree, or different preset opening degrees may be used. The second time period may take any value from 3min to 8min, for example.
And B3, circularly executing the steps until the outlet air temperature is equal to or greater than the first temperature threshold, and controlling the air conditioner to continue to operate at the current opening of the expansion valve. The air conditioner continues to operate at the current opening degree of the expansion valve, and exits the current health air conditioning function.
In this embodiment, if the outlet air temperature is lower than the first temperature threshold, it indicates that the current outlet air temperature is too low and may damage the target object, and the outlet air temperature needs to be raised. Through reducing the expansion valve opening, can promote the air-out temperature, every expansion valve opening only moves for a certain time, can prevent the adverse effect of long-time low temperature air-out, reduces refrigeration effect at a certain degree, slows down the speed that ambient temperature reduces.
Considering the need of active control of the user, the method also provides a mechanism for the user to select whether to enter the staged cooling function, and based on this, the method also comprises: and if the health air-conditioning mode operation is received, the air conditioner is controlled to cool down in stages. By providing a user with a selection mechanism whether to enter the healthy air-conditioning mode, the user experience may be improved.
The control method of the air conditioner provided by the embodiment can judge through the indoor and outdoor ambient temperature and temperature difference, the human body temperature and the set temperature, can improve the pertinence of the step-by-step cooling function, and avoids error prompt; the step-by-step cooling function is started under the satisfied condition, so that the temperature can be slowly reduced under the condition of higher body temperature of people, and the uncomfortable feeling of the body caused by quick cooling is reduced.
