Firstly, determining the product of V and V according to the current wind gear value K, wherein V is the circulating air volume of the irradiation area of the germicidal lamp and is the death rate of bacteria passing through the irradiation area of the germicidal lamp once, and the value of V is larger as the passing time of the bacteria and the performance of the germicidal lamp are higher, and the retention time of air in the irradiation area of the germicidal lamp is correspondingly reduced, namely the value is reduced.

The formula for calculating the product of V and is:

V*＝-C₂(k–C₀)²+C₁；

in the formula, C₀、C₁、C₂Are constants that correlate to the performance of the germicidal lamp.

Then, the turn-on time period T of the germicidal lamp is determined based on the product of the indoor space volumes R and V.

The calculation formula of the starting time T is as follows:

in the formula, m is the air conditioner sterilization rate, n is the number of the germicidal lamps, and in this embodiment, the value of the number n of the germicidal lamps is 4.

In the above formula, the calculation formula of the air conditioner sterilization rate m is as follows:

Second embodiment

Referring to fig. 2, the present embodiment provides an air conditioner 100, and the air conditioner 100 includes a controller 110, a distance sensor 120 and a germicidal lamp 130. The distance sensor 120 is installed on the air outlet panel of the air conditioner 100, and the distance sensor 120 can detect the distance d between the air conditioner and the wall opposite to the air conditioner and transmit the distance d to the controller 110. The germicidal lamps 130 are installed inside the air conditioner 100, the germicidal lamps 130 are used for sterilizing air flowing through, the number of the germicidal lamps 130 is four, and the germicidal lamps 130 are deep ultraviolet radiation lamps.

The distance sensor 120 and the germicidal lamp 130 are both electrically connected to the controller 110. The controller 110 is provided with a preset program, and the controller 110 can determine the starting time T of the germicidal lamp 130 according to the distance d between the air conditioner and the opposite wall of the air conditioner and the current wind gear value K according to the preset program; the controller 110 is further configured to control the germicidal lamp 130 to be turned on and to turn off the germicidal lamp 130 after the turn-on duration T.

The specific implementation of the controller 110 is as follows:

first, after the controller 110 receives an on command of the sterilization function, the controller 110 acquires the distance d detected by the distance sensor 120 and calculates the indoor space volume R from the distance d. The opening instruction of the sterilization function can be directly sent to the air conditioner by a user through a remote controller, and a program can also be set in the air conditioner, so that the air conditioner automatically opens the one-time sterilization function at a fixed interval.

Wherein, the calculation formula of the indoor space volume R is as follows:

therefore, the indoor space volume R can be automatically calculated by detecting the distance d between the air conditioner and the opposite wall of the air conditioner and according to a preset calculation formula, and the indoor space volume R is the sterilization space volume.

In this embodiment, the indoor space volume R is estimated according to the distance d between the air conditioner and the wall opposite to the air conditioner. In other embodiments, the indoor space volume R may be input into the air conditioner 100, and the controller 110 of the air conditioner 100 may directly call the indoor space volume R input in advance for subsequent calculation.

After the controller 110 receives the start instruction of the sterilization function, the controller 110 detects the current wind level and calculates the current wind level value K according to the current wind level. The air damper of the air conditioner 100 may be divided into: low wind gear, medium wind gear, high wind gear and strong gear. In the program of the air conditioner 100, the following are set: when the current wind gear is a low wind gear, the current wind gear value K is 1; when the current gear is the middle gear, the current gear value K is 2; when the current wind gear is a high wind gear, the current wind gear value K is 3; and when the current gear is a strong gear, the current gear value K is 4.

The detection of the current gear value K and the acquisition of the indoor space volume R may be performed by the controller 110 at the same time, and in control logic, there is no need to distinguish a sequence.

Then, the controller 110 calculates the product of V and V according to the current wind level value K, where V is the circulating air volume in the irradiation area of the germicidal lamp 130 and is the death rate of bacteria once passing through the irradiation area of the germicidal lamp 130, and the value of V is larger as the passing time of bacteria and the wind speed of the germicidal lamp 130 air conditioner 100 are higher, which correspondingly reduces the retention time of air in the irradiation area of the germicidal lamp 130, i.e., the value is reduced.

Wherein, the calculation formula of the product of V and V is as follows:

V*＝-C₂(k–C₀)²+C₁；

in the formula, C₀、C₁、C₂Are constants that correlate to the performance of the germicidal lamp 130.

Next, the controller 110 calculates the turn-on time period T of the germicidal lamp 130 based on the product of the indoor space volumes R and V.

The calculation formula of the starting time T is as follows:

in the formula, m is the air conditioner sterilization rate, n is the number of the germicidal lamps 130, and in this embodiment, the value of the number n of the germicidal lamps 130 is 4.

In the above formula, the calculation formula of the air conditioner sterilization rate m is as follows:

m＝1-exp(-nVT/R)。

in the present embodiment, the first and second electrodes are,the value range of the set value is as follows: the value of-0.06 to-0.04 can be specifically-0.05, and the opening time length T can be calculated according to a calculation formula of the opening time length T.

All calculation formulas used by the controller 110 are stored in the controller 110 in the form of a program.

Finally, the controller 110 controls the germicidal lamp 130 to be turned on and turns off the germicidal lamp 130 after the turn-on duration T.

Thus, with the air conditioner 100 according to the embodiment of the present invention, after receiving the start instruction of the sterilization function sent by the user, the controller 110 of the air conditioner 100 automatically calculates the start time T of the germicidal lamp 130 step by step according to the distance d between the air conditioner and the opposite wall of the air conditioner and the current wind level value K, and controls the germicidal lamp 130 to be turned on and to be turned on continuously for the time T, and then automatically turns off the germicidal lamp 130, so as to prevent the germicidal lamp 130 from being turned on too short to reach the sterilization effect, and prevent the germicidal lamp 130 from being turned on too long to reduce the service life of the germicidal lamp 130.

In addition, according to the characteristics that the germicidal lamp 130 increases along with the turn-on time T and the sterilization efficiency decreases, the air conditioner 100 provided in this embodiment sets the appropriate turn-on time T for the germicidal lamp 130 according to the specific use scenario, thereby avoiding the occurrence of the ultraviolet module life waste caused by too short sterilization time and insufficient sterilization effect or too long turn-on time.

The technical core of the control method for the UVC sterilization function of the air conditioner and the air conditioner 100 provided by the embodiment of the invention is as follows: firstly, estimating the indoor space volume R according to the distance measurement of the distance sensor 120; then, according to the performance parameters of the germicidal lamp 130, obtaining the relation between the product of the circulating air volume V of the irradiation area of the germicidal lamp 130 and the death rate of bacteria once passing through the irradiation range of the germicidal lamp 130 and the current wind gear value K; finally, the on-time T of the germicidal lamp 130 is determined according to the air conditioner germicidal rate m and the threshold of the partial derivative of the on-time T.

In the control method of the UVC sterilization function of the air conditioner and the air conditioner 100 provided by the embodiment of the present invention, the turn-on time T of the germicidal lamp is gradually calculated by using the indoor space volume R and the current wind level value K, and a plurality of calculation formulas are applied in the calculation process, and are all suitable formulas designed or selected by the applicant. The skilled person can of course also use other calculation formulas to calculate, but as long as the switching-on time T of the germicidal lamp is calculated based on the indoor space volume R and the current wind level value K, such a concept should fall within the scope of the present application.
