In the foregoing description of embodiments, the particular features, structures, materials, or characteristics may be combined in any suitable manner in any one or more embodiments or examples.
Referring to fig. 1, an LED lamp 300 is disposed inside an air conditioner indoor unit 200, and UVC 310 emitted by the LED lamp 300 is used for sterilizing air flowing through the air conditioner indoor unit 200 to improve indoor air quality.
When the UVC 310 emitted by the LED lamp 300 sterilizes air, a UVC dangerous area 320 that may damage a human body is also formed, and if a human body 400 enters the UVC dangerous area 320 during an installation or maintenance process of the indoor unit 200, an operator may damage the human body 400 by the UVC 310.
An object of the present invention is to improve an indoor unit 200, which can sterilize and purify air using a UVC 310 and prevent the UVC 310 from damaging a human body.
Specifically, the protection device 100 is further provided inside the indoor unit 200, and referring to fig. 2, the protection device includes a detection unit 110 and an analysis control unit 120.
The detection unit 110 is used for detecting whether a human body 400 enters or is about to enter the UVC risk region 320.
The analysis control unit 120 is configured to receive and analyze the detection information fed back by the detection unit 110, and the analysis control unit 120 is electrically connected to the LED lamp 300 and can control the on/off of the LED lamp 300 according to the analysis result.
When the analysis result of the analysis control unit 120 indicates that the human body 400 enters the UVC dangerous area 320, the analysis control unit 120 controls the LED lamp 300 to turn off, so as to prevent the UVC 310 emitted by the LED lamp 300 from irradiating the human body to hurt the human body.
As a preferred embodiment, referring to fig. 1 and 2, the detecting unit 110 includes a light emitting unit 111 and a light receiving unit 112, wherein the light emitting unit 111 is disposed inside the indoor unit 200 and electrically connected to the analysis control unit 120 through a wire, and the light receiving unit 112 is also disposed inside the indoor unit 200 and electrically connected to the analysis control unit 120 through a wire.
When a person enters or is about to enter the UVC dangerous area 320, the light emitted from the light emitting portion 111 touches the human body 400, the light is reflected to the light receiving portion 112 by the human body 400, and the light receiving portion 112 receives the reflected light and feeds back the detection information to the analysis control unit 120.
The analysis control unit 120 analyzes and judges whether a human body enters the UVC risk region 320 according to the received detection information, and if so, controls the LED lamp 300 to turn off, and stops radiating the UVC 310, thereby preventing the UVC 310 from damaging the human body.
Further, an included angle between the light emitted from the light emitting portion 111 and the UVC 310 is an acute angle, which is labeled as α, so that when the human body 400 approaches the UVC dangerous area 320 from different angles, the light emitted from the light emitting portion 111 can touch the human body 400 and be reflected to the light receiving portion 112, thereby detecting whether the human body 400 enters or is about to enter the UVC dangerous area 320.
If the included angle between the light emitted from the light emitting portion 111 and the UVC 310 is 0 °, that is, the light emitted from the light emitting portion 111 is parallel to the UVC 310, at this time, when the light emitted from the light emitting portion 111 touches the human body 400, it means that the UVC 310 also irradiates the human body 400, and at this time, the UVC 310 will cause damage to the human body 400, and the protection device 100 loses the effect of preventing in advance.
If the angle between the light emitted from the light emitting portion 111 and the UVC 310 is greater than or equal to 90, when the human body 400 approaches the UVC risk region 320 from the direction opposite to the irradiation direction of the UVC 310, the light emitted from the light emitting portion 111 may touch the human body 400, and actually, although the human body 400 approaches the UVC risk region 320, since the human body 400 is located at the backlight side of the UVC 310, the UVC 310 may not irradiate the human body 400, it may be meaningless to detect whether the human body 400 enters the UVC risk region 320.
In a preferred embodiment, the angle between the light emitted from the light emitting portion 111 and the UVC 310 is less than 60 °, so that the detecting unit 110 can detect whether the human body 400 enters or is about to enter the UVC danger area 320 more effectively.
In a preferred embodiment, the light emitting part 111 emits infrared rays, and the light receiving part 112 receives infrared rays.
In other embodiments, the light emitting portion 111 may emit light such as laser light that does not harm the human body 400, and the light receiving portion 112 may receive the light.
As a preferred embodiment, the light emitting part 111 and the light receiving part 112 are fixed to the LED lamp 300, and referring to fig. 1, the light emitting part 111 and the light receiving part 112 are located at the center of the UVC risk region 320, so that the detection result is more accurate.
On the basis of the above embodiments, the protection device 100 further performs the following control optimization to realize accurate control of the start and stop of the LED lamp 300.
Specifically, the intensity of the light received by the light receiver 112 is represented by Q, and the closer the human body 400 is to the light receiver 112, the greater the Q value, and after the indoor unit 200 is installed and fixed, the safety value △ Q0 of the intensity of the light received by the light receiver 112 is fixed.
The safety value △ Q0 of the intensity of the light received by the light receiving part 112 may be understood as the human body 400 does not enter the UVC risk region 320 at this time.
When the human body 400 moves in the vicinity of the indoor unit 200, the Q value changes, and the difference in the intensity of the light received by the light receiving unit 112 in two adjacent times is defined as △ Q1.
Referring to fig. 3, when △ Q1 is greater than △ Q0, which indicates that the human body 400 enters the UVC risk region 320, the analysis control unit 120 controls the LED lamp 300 to turn off, and when △ Q1 is less than or equal to △ Q0, which indicates that the human body 400 does not enter the UVC risk region 320, the analysis control unit 120 controls the LED lamp to turn on.
In practical applications, the human body 400 is only temporarily shaken into the UVC danger zone 320 and does not stay in the UVC danger zone 320, and the UVC 310 has minimal damage to the human body 400, and if the LED lamp 300 is turned off immediately in such a case, and the LED lamp 300 is turned on immediately after the human body 400 leaves, the LED lamp 300 is frequently turned on or off, which causes unnecessary energy consumption and reduces the service life of the LED lamp 300.
To solve this problem, the protection device 100 is further optimized for control as follows.
Specifically, referring to fig. 3, when △ Q1 is greater than △ Q0 and continues for a time t1, which indicates that the human body 400 has entered the UVC dangerous area 320 and stayed for a period of time, the UVC 310 will cause injury to the human body 400, the analysis control unit 120 will control the LED lamp 300 to turn off, and when △ Q1 is less than or equal to △ Q0 and continues for a time t1, which indicates that the human body 400 has left the UVC dangerous area 320, the analysis control unit 120 will control the LED lamp 300 to turn on, so as to solve the problem that the LED lamp 300 is unnecessarily frequently turned on.
In other embodiments, the on/off of the LED lamp 300 may also be controlled according to whether the human body 400 frequently enters the UVC danger area 320. Because if the human body 400 frequently enters the UVC risk region 320, although the time for a single time in the UVC risk region 320 is short, the time for which the UVC 310 cumulatively acts on the human body 400 is also long and the human body 400 is also damaged due to frequent entering within a certain period of time.
Specifically, referring to fig. 3 as well, when △ Q1 is greater than △ Q0 and n1 times are accumulated, it indicates that the human body 400 frequently enters the UVC risk area 320 within a certain time period at this time, the analysis control unit 120 controls the LED lamp 300 to turn off, and when △ Q1 is less than or equal to △ Q0 and n1 times are accumulated, it indicates that the human body 400 is far away from the UVC risk area 320 within a certain time period at this time, the analysis control unit 120 controls the LED lamp to turn on.
On the basis of the above embodiment, referring to fig. 2, the protection apparatus 100 further includes an alarm unit 130 electrically connected to the analysis control unit 120, wherein the alarm unit 130 gives an alarm when a person enters the UVC risk area 320.
The alarm unit 130 may alarm the person by means of sound, light, APP push message, etc.
The operation of the protection device 100 will be described in detail below with reference to fig. 3.
Step S1: firstly, the LED lamp 300 receives a lamp-on instruction;
step S2: the detection unit 110 will first detect whether a person enters or is about to enter the UVC danger area 320, and the detection unit 110 will feed back the detection result to the analysis control unit 120;
step S3: the analysis control unit 120 analyzes and judges the detection result;
step S4, if △ Q1 is larger than △ Q0 and the continuous time t1 (or n1 times) indicates that the person enters the UVC dangerous area 320 at the moment, the alarm unit 130 gives an alarm, and the person hears the alarm and then responds correspondingly, and the step S2 is returned;
step S5, if △ Q1 is less than or equal to △ Q0 and the continuous time t1 (or n1 times), it indicates that no one enters the UVC dangerous area 320 at this time, and the LED lamp 300 can be safely turned on;
when the LED lamp 300 is turned on, it is still necessary to continuously detect whether the human body 400 enters the UVC risk region 320;
step S6: repeating the step 2;
step S7: repeating the step 3;
step S8, if △ Q1 is larger than △ Q0 and the continuous time t1 (or n1 times) is reached, the LED lamp 300 is turned off to prevent the UVC 310 from harming the human body, wherein the situation shows that a person enters the UVC dangerous area 320 at the moment;
step S9: the alarm unit 130 issues an alarm to remind people to get away from the UVC danger area 320;
and step S10, if △ Q1 is less than or equal to △ Q0 and the continuous time t1 (or n1 times), which indicates that no person enters the UVC dangerous area 320 at the moment, the LED lamp can continuously keep on, and the step S6 is returned.
