Background
With the continuous progress of economy, the application of the air conditioner is more and more extensive, and the air conditioner can bring comfortable experience to users by adjusting the indoor environment temperature, so that the air conditioner becomes one of the most common household appliances. However, in general, when the room temperature is high, the user feels very cool when blowing cool wind, and when the room temperature is gradually lowered to a certain degree, even if the user is blown by very slight wind, the user feels discomfort, which results in a reduction in the user experience.
In the prior art, whether the air conditioner needs to enter the comfort air mode is usually determined by the temperature difference between the indoor environment temperature and the set temperature, but the indoor environment temperature can be changed in real time, that is, the temperature difference between the indoor environment temperature and the set temperature can also be changed in real time, and the air conditioner can exit the comfort air mode once the temperature difference rises under normal conditions, so that the air conditioner can frequently switch the operation mode, and the comfort of a user is poor.

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.
The embodiment of the invention provides an air conditioner 100, which is used for adjusting indoor temperature and ensuring that a user has comfortable use experience at any time. Referring to fig. 1, a functional block diagram of an air conditioner 100 according to the present invention is shown. The air conditioner 100 includes: the device comprises a memory 120, a controller 110, a temperature detection module 130, a fan 140, an air guide mechanism 150 and a body feeling air volume adjusting device 200. The controller 110 is electrically connected to the memory 120, the temperature detection module 130, the fan 140, and the wind guiding mechanism 150. The somatosensory air volume adjusting device 200 comprises at least one of the devices which can be stored in the memory 120 in the form of software or firmware (firmware).
Memory 120 may be used to store software programs and units, such as program instructions/units corresponding to the somatosensory air volume adjusting device 200 and the method in the embodiments of the present invention, and controller 110 may execute various functional applications and data processing, such as the somatosensory air volume adjusting method provided in the embodiments of the present invention, by running the software programs and units of the somatosensory air volume adjusting device 200 and the method stored in memory 120.
The Memory 120 may be, but is not limited to, a Random Access Memory (RAM), a Read Only Memory (ROM), a Programmable Read-Only Memory (PROM), an Erasable Read-Only Memory (EPROM), an electrically Erasable Read-Only Memory (EEPROM), and the like.
The temperature detection module 130 is configured to detect an indoor ambient temperature and transmit the indoor ambient temperature to the controller 110.
In a preferred embodiment, the temperature detection module 130 includes a temperature sensor.
The fan 140 is used to adjust the wind speed under the control of the controller 110.
The air guide mechanism 150 is used for adjusting the angle of the air guide door under the control of the controller 110.
Specifically, the air guide door angle includes an inner air guide door angle and an outer air guide door angle.
The adjustment of the sensible air quantity can be realized by adjusting the air speed and/or the angle of the air guide door.
It will be appreciated that the configuration shown in fig. 1 is merely illustrative and that the air conditioner 100 may include more or fewer components than shown in fig. 1 or may have a different configuration than shown in fig. 1. The components shown in fig. 1 may be implemented in hardware, software, or a combination thereof.
The invention provides a somatosensory air volume adjusting method, which is applied to an air conditioner 100 and used for adjusting indoor temperature, ensuring that a user has comfortable use experience at any time and avoiding the problem that the air conditioner 100 frequently switches operation modes due to inaccurate temperature control. Please refer to fig. 2, which is a flowchart of the method for adjusting the sensible air volume according to the present invention. The somatosensory air volume adjusting method comprises the following steps:
and S201, determining a temperature difference according to the acquired indoor environment temperature and the set temperature at intervals of a preset second time interval.
It is understood that the indoor ambient temperature may be detected by a temperature sensor of the air conditioner 100. In addition, the set temperature is the temperature set by the user according to the self requirement, and the set temperature can be changed according to the change of the requirement of the user.
In an alternative embodiment, the controller 110 obtains the indoor environment temperature and the set temperature in real time, but calculates the temperature difference between the indoor environment temperature and the set temperature every preset second time interval.
Specifically, the difference between the indoor ambient temperature and the preset temperature reference value is calculated every preset second time interval. Let the indoor ambient temperature detected in the ith second be TAiSetting the temperature to TSiThen, every preset time interval, the delta T is calculated as TAi-Tsi。
In an alternative embodiment, the predetermined second time interval is 180 seconds. Then Δ T is calculated in turn0s＝TA0s-TS0s、ΔT180s＝TA180s-TS180s、ΔT360s＝TA360s-TS360sAnd so on. It should be noted that the preset time interval may have other values.
It should be noted that, after the air conditioner 100 is turned on and operated for a period of time, the temperature difference between the indoor ambient temperature and the set temperature is determined every a preset second time interval. Generally, the change of the indoor ambient temperature is not great during the startup of the air conditioner 100, and at this time, determining the temperature difference between the indoor ambient temperature and the set temperature generally only brings more operation burden to the controller 110; however, after the air conditioner 100 is turned on and operated for a period of time, the temperature difference between the indoor ambient temperature and the preset temperature reference value is determined, and at this time, the indoor ambient temperature has been changed under the adjustment of the air conditioner 100, which can be used as a basis for executing the subsequent steps. In an alternative embodiment, S201 is executed after the air conditioner 100 is powered on and operated for 4 min.
S202, judging whether the temperature difference meets a first preset condition, if so, executing S203; if not, S201 is re-executed.
In an optional embodiment, when the current temperature difference is less than or equal to the preset second threshold and there are three temperature differences determined in two adjacent second time intervals that decrease sequentially in time sequence, the temperature difference satisfies the first preset condition.
Specifically, when the current temperature difference is less than or equal to the preset second threshold value, it indicates that the indoor ambient temperature is closer to the set temperature, and meanwhile, because three temperature differences determined in two adjacent second time intervals are sequentially reduced according to a time sequence, that is, the difference between the indoor ambient temperature and the set temperature is smaller and smaller, the indoor ambient temperature is closer and closer to the set temperature, so that under the condition that the indoor ambient temperature is close to the user requirement, the body feeling air volume needs to be further adjusted to increase the comfort level of the user, and therefore the user needs to enter a comfortable air mode when the condition is met.
For example, Δ T0s、ΔT180sAnd Δ T360sIs three temperature differences determined in two adjacent second time intervals, when the temperature difference is delta T360s<T2And Δ T0s<ΔT180s<ΔT360sWhen the temperature difference meets a first preset condition; otherwise, the temperature difference does not satisfy the first preset condition. It is composed ofIn, T2Is a preset second threshold value.
In another optional embodiment, when the current temperature difference is less than or equal to the second preset threshold and the indoor ambient temperature is less than or equal to the sixth preset temperature threshold, the temperature difference satisfies the first preset condition.
The sixth temperature threshold is a temperature that can make a user comfortable in a normal state. Therefore, when the current temperature difference is less than or equal to the preset second threshold, it indicates that the indoor ambient temperature is closer to the set temperature, and meanwhile, because the indoor ambient temperature is less than or equal to the preset sixth temperature threshold, that is, the indoor ambient temperature is lower than the temperature at which the user feels comfortable, if the air output of the air conditioner 100 is too large, the user feels too cold, and therefore the air volume is further adjusted to increase the comfort of the user, and therefore the user needs to enter a comfortable air mode when the condition is met.
In an alternative embodiment, the preset second threshold is 2 ℃ and the preset sixth temperature threshold is 27 ℃.
And S203, entering a comfortable air mode, and determining a target air speed and/or a target angle of the air guide door according to the current temperature difference and the indoor environment temperature based on a preset second standard so as to adjust the somatosensory air quantity.
It should be noted that the current temperature difference is the last determined temperature difference of the three temperature differences determined in two adjacent second time intervals which decrease in time sequence, such as the Δ T described above360s。
It is understood that the sensible air volume refers to an air volume that a user can feel. Generally, under the condition that the wind speed is not changed, the larger the angle of the wind guide door is, the larger the sensible wind quantity is; and under the condition that the angle of the air guide door is not changed, the higher the air speed is, the larger the sensible air quantity is.
Specifically, please refer to fig. 3, which is a flowchart illustrating the step S203. The step S203 includes:
s2031, judging whether the current temperature difference is less than or equal to a preset first temperature difference threshold value, if so, executing a substep S2032; if not, then substep S2033 is performed.

In an alternative embodiment, the first temperature difference threshold T1At 0 deg.C, a second temperature difference threshold T2Is 1 ℃ and a third temperature difference threshold T3Is 2 ℃. It is also to be noted that the first temperature difference threshold value T1A second temperature difference threshold T2And a third temperature difference threshold T3Other values are possible, and the above conditions are satisfied. By judging the interval of the current temperature difference, the approach degree of the indoor environment temperature and the set temperature can be determined.
S2032, determining the target wind speed as the preset mute wind speed, and/or determining the target angle of the air guide door as the preset first angle of the air guide door.
That is, when Δ T ≦ T1When the target angle of the air guide door is kept unchanged, the target wind speed can be determined to be the preset mute wind speed; or under the condition that the target wind speed is kept unchanged as the current wind speed, determining that the target angle of the air guide door is a preset first angle of the air guide door; or simultaneously determining the target wind speed as the preset mute wind speed and determining the target angle of the air guide door as the preset first angle of the air guide door.
In the present embodiment, three thresholds of the silent wind speed, the low wind speed and the medium wind speed are set for the target wind speed, and the silent wind speed, the low wind speed and the medium wind speed are sequentially increased; meanwhile, two thresholds of a first angle of the air guide door and a second angle of the air guide door are set for the target angle of the air guide door, and the first angle of the air guide door is smaller than the second angle of the air guide door.
It should be noted that the target angle of the air guiding door includes a target angle of an outer air guiding door and/or a target angle of an inner air guiding door, the first angle of the air guiding door includes a first angle of the outer air guiding door and/or a first angle of the inner air guiding door, and the second angle of the air guiding door includes a second angle of the outer air guiding door and/or a second angle of the inner air guiding door. The first angle of the outer air guide door is smaller than the second angle of the outer air guide door, and the first angle of the inner air guide door is smaller than the second angle of the inner air guide door.

In addition, in the embodiment, the fan blade rotating speed corresponding to the mute wind speed ranges from 400 to 600 rpm, and the fan blade rotating speed corresponding to the low wind speed ranges from 700 to 1000 rpm.
Thus, when Δ T ≦ T1When, it indicates that the current temperature difference is very little, also is that indoor ambient temperature is very close with the settlement temperature, feels the amount of wind too high this moment if, can cause uncomfortable experience for the user. Therefore, the mute wind speed with the minimum target wind speed is determined, and/or the target angle of the air guiding door is determined to be the first angle of the air guiding door with a smaller angle, so that the air output of the air conditioner 100 is reduced, and comfortable experience is brought to users as much as possible.

When T is1<ΔT≤T2And meanwhile, the indoor environment temperature is close to the preset temperature reference value, and the wind speed and/or the angle of the wind guide door also need to be further adjusted to adjust the somatosensory wind quantity. However, when the current temperature difference is smaller than or equal to the first temperature difference threshold, the air output of the air conditioner 100 should be further determined whether to be adjusted according to the indoor ambient temperature.

It should also be noted that the fourth temperature threshold TW4A fifth temperature threshold TW5And a sixth temperature threshold TW6The fourth temperature threshold T may be satisfied at other valuesW4A fifth temperature threshold TW5And a sixth temperature threshold TW6The relationship of increasing in order. The current body sensing temperature of the user can be determined by judging the interval where the current indoor environment temperature is located.
Specifically, when T isA≤TW4And TW4<TA≤TW5And then, determining the target wind speed as the preset mute wind speed. That is, when TA≤TW5Due to the indoor ambient temperature TAVery low, and at the moment, if the body feeling air quantity is too high, discomfort can be caused to the userExperience, and therefore the target wind speed is determined to be the lowest, silent wind speed.
When T isW5<TA≤TW6And determining the target wind speed as the smaller value of the preset low wind speed and the preset wind speed set value. Because the indoor environment temperature T is at the momentALower, but due to the room ambient temperature TAHigher than TA≤TW5Indoor ambient temperature T of timeATherefore, the sensible air volume bearable for the user is relative to TA≤TW5More sensible air quantity can be borne, so as to ensure the indoor environment temperature TAAt this time, the wind speed can be properly adjusted, and the target wind speed is determined to be the smaller value of the preset low wind speed and the preset wind speed set value.
When T isA>TW6And determining the target wind speed as the smaller value of the preset medium wind speed and the preset wind speed set value. Because the indoor environment temperature T is at the momentAHigher, but due to the room ambient temperature T at this timeAHigher than TW5<TA≤TW6Indoor ambient temperature T of timeATherefore, the sensible air volume bearable for the user is relative to TW5<TA≤TW6More sensible air quantity can be borne, so as to ensure the indoor environment temperature TAAt this time, the wind speed can be properly adjusted, and the target wind speed is determined to be the smaller value of the preset medium wind speed and the preset wind speed set value.

And S204, determining a temperature difference according to the acquired indoor environment temperature and the set temperature at preset first time intervals.
It should be noted that, from the moment when the comfort wind mode is entered, the difference between the indoor ambient temperature and the set temperature is calculated for the first time, and then the difference between the indoor ambient temperature and the set temperature is calculated again every preset first time interval. However, since the air conditioner 100 has already entered the comfort wind mode at this time, it is not necessary to accurately control the temperature of the air conditioner 100 to enter the comfort wind mode, and the second time interval is greater than the first time interval in order to avoid the pressure of the controller 110 caused by frequent calculation. In an alternative embodiment, the second time interval is 360 seconds.
It can be understood that, after entering the comfort wind mode, the temperature difference is not required to be determined according to the acquired indoor environment temperature and the set temperature at preset second time intervals.

And S206, based on a preset second standard, determining a target wind speed and/or a target angle of the air guide door according to the current temperature difference and the indoor environment temperature so as to adjust the somatosensory air quantity.
When the difference between two adjacent temperature differences is smaller than 0, it indicates that the temperature difference is in a descending trend, that is, the indoor environment temperature is lower and lower relative to the set temperature, and at this moment, if the air output of the air conditioner 100 is too large, the user feels too cold, so that the user comfort level needs to be increased by further adjusting the body feeling air volume.
It can be understood that this step is similar to the specific method of determining the target wind speed and/or the target angle of the air guiding door to adjust the somatosensory air volume according to the current temperature difference and the indoor environment temperature based on the preset second criterion in S203, and the specific content please refer to S203, which is not described herein again.

when the difference between the two adjacent temperature differences is smaller than or equal to the preset first threshold, it indicates that the change degree of the temperature differences is not large, so that the current air output of the air conditioner 100 can be kept unchanged, and therefore the target air speed is determined as the current air speed and the target angle of the air guide door is determined as the current air guide door angle.
S209, based on a preset first standard, determining a target wind speed and/or a target angle of the air guide door according to the current temperature difference and the indoor environment temperature so as to adjust the somatosensory air quantity.
