The invention provides an air duct component which comprises the sterilizing device.
The invention provides an air conditioner which comprises the air duct component.
The invention provides a sterilization method, which is suitable for the sterilization device and comprises the following steps: when the sterilization function is turned on, themotor 300 of the air duct part is controlled to rotate; when the firstmagnetic induction sensor 41 detects themagnetic member 3, controlling thegermicidal lamp 1 to operate at maximum power and maximum brightness; when the secondmagnetic induction sensor 42 detects themagnetic member 3, the power and the brightness of thegermicidal lamp 1 are adjusted downwards; the steps starting when the firstmagnetic induction sensor 41 detects themagnetic member 3 are repeated.
The sterilization function of the invention is started by pressing the sterilization key on the body of the air conditioner or the remote controller, and is closed by pressing the sterilization key on the body of the air conditioner or the remote controller.
The germicidal device of the present invention changes the magnitude of the output voltage by controlling the on and off durations of the switching device of the germicidallamp driving module 402 per unit time to adjust the duty cycle (PWM) of the switching signal of the output voltage, thereby adjusting the power and brightness of the germicidal lamp.
For example, in a unit time (microsecond), the time when the switching device is turned on is N, and the time when the switching device is turned off is T, so that the duty ratio N is N/T, the output voltage U is 12N/T, and the power of thegermicidal lamp 1 is proportional to the output voltage U.
As shown in fig. 3, when the air conditioner is in an initial state when the sterilization function is not turned on, thegermicidal lamp 1 is not powered on and is in an off state by default to prevent the outside of the air conditioner from being irradiated by high-brightness ultraviolet rays, and when a user does not press a sterilization key on the remote controller, the air conditioner operates according to other conventional functions.
When a user presses a sterilization key on a remote controller, a main control chip 401 (namely, a Micro Control Unit (MCU)) on the controlmain board 400 sends a control signal to amotor driving module 403 to control an output shaft of amotor 300 to rotate so as to drive thecross-flow fan blade 200 and asterilization lamp 1, a balancingweight 2 and amagnetic part 3 which are positioned on thecross-flow fan blade 200 to synchronously rotate together; the twomagnetic induction sensors 4 detect the position of themagnetic piece 3 in real time; when the firstmagnetic induction sensor 41 detects the magnetic signal of themagnetic member 3, it can be determined that thegermicidal lamp 1 will rotate to enter the inside of the air-out frame 100; the specific process is as follows:
(1) when thegermicidal lamp 1 rotates to the inner side of the air-out frame 100, the irradiation direction of thegermicidal lamp 1 faces the inner side of the air-out frame 100, the irradiated area is the bottom shell air duct, the inner side of the evaporator, the fan blade and the like, and the irradiation direction of thegermicidal lamp 1 faces the inside of the air conditioner, so that the ultraviolet radiation quantity within 0.3m of the outer side of the air-out frame 100 does not exceed the requirement of the electrical safety standard (namely the ultraviolet radiation quantity is less than or equal to 0.2uW/cm 2). Therefore, the power and brightness of thegermicidal lamp 1 can be adjusted by adjusting the duty ratio, and themain control chip 401 is controlled to output the maximum duty ratio to the germicidallamp driving module 402, so that thegermicidal lamp 1 is turned on and irradiates with the maximum power, the maximum brightness and the maximum radiation degree, and the optimal germicidal effect is achieved.
(2) When the secondmagnetic induction sensor 42 detects the magnetic signal of themagnetic member 3, it can be determined that thegermicidal lamp 1 will rotate to the air outlet of the air-out frame, and the air outlet is only blocked by the edge of the air outlet, the upper and lower air deflectors, and the left and right air-sweeping blades, and there are many gaps therebetween, and the ultraviolet rays are easily irradiated into the space outside the air-out frame 100 within the range of 0.3m, and the radiation amount thereof easily exceeds the requirement of the electrical safety standard (i.e. the radiation amount of the ultraviolet rays is less than or equal to 0.2uW/cm 2). Therefore, the power and the brightness of thegermicidal lamp 1 need to be reduced by adjusting the duty ratio, the duty ratio output by themain control chip 401 is controlled to be reduced to N%, and then the power of thegermicidal lamp 1 is reduced to N% and the brightness is also reduced to N% through the germicidallamp driving module 402, so that a better germicidal effect is achieved on the premise that the ultraviolet radiation amount meets the electrical safety standard.
(3) And (3) repeating the steps (1) and (2) until the user presses a sterilization closing key on the air conditioner to close the sterilizinglamp 1 and finish the sterilizing function.
The N value is obtained by measuring the radiation quantity value of the inner machine of the air conditioner in the range of 0.3m by using an ultraviolet tester through the equivalent down-regulation duty ratio and comparing the radiation quantity value with the required value of the electrical safety standard, and the specific calculation method comprises the following steps: setting the duty ratio N percent to 99 percent, measuring the radiation quantity under the duty ratio, if the radiation quantity is more than 0.2uW/cm2, setting the duty ratio N percent to 98 percent, measuring the radiation quantity under the space ratio, and adjusting the duty ratio downwards in sequence until the ultraviolet radiation quantity is less than or equal to 0.2uW/cm2, thus determining the value of N.
From the above description, it can be seen that the above-described embodiments of the present invention achieve the following technical effects:
