Detailed Description
The embodiments of the invention will be described in detail below with reference to the drawings, but the invention can be implemented in many different ways as defined and covered by the claims.
Example 1:
photodynamic sterilization refers to that a photosensitizer absorbed by bacterial cell tissues generates photochemical reaction through irradiation of light with specific wavelength to generate singlet oxygen, and the singlet oxygen can cause bacteria to die. At present, the sterilization method is widely used in clinical medicine with extremely high targeting and inactivation rate. In the related technology, the air-conditioning sterilization mode comprises high temperature, ultraviolet irradiation and other modes, the methods only can play a role in sterilization temporarily and cannot play a role in directional sterilization, the photodynamic sterilization originates from the treatment of cancers, and the directional sterilization effect is obvious by matching with a special photosensitizer and a light source with a specific wavelength.
Since the air conditioner in the related art can not kill harmful bacteria directionally, the embodiment of the invention aims to provide an air conditioner sterilization device, as shown in fig. 1, the air conditioner sterilization device is installed in an air conditioner indoor unit and comprises a guide rail and a movable sterilization assembly arranged on the guide rail, the sterilization assembly comprises an excitation light source 11 and a photosensitizer injection device 12, the photosensitizer injection device 12 injects photosensitizer into an area to be sterilized of the air conditioner, and for the air conditioner indoor unit, a heat exchanger and a filter screen are areas where bacteria are easy to breed.

As stated above, the areas of the heat exchanger and the filter screen are large, the partition blocks are required to be partitioned for sterilization, and therefore the sterilization component is required to be movable, the embodiment of the invention is provided with the guide rail comprising the first direction slide bar 1 and the second direction slide bar 2, the sterilization component is slidably arranged on the first direction slide bar 1, the sterilization component is driven by the motor to move on the first direction slide bar 1, for the purpose of illustration, the first direction slide bar 1 is a horizontal slide bar, the second direction slide bar 2 is a slide bar vertical to the horizontal direction, and the horizontal direction in the embodiment taking the split type hanging machine as an example is generally the horizontal direction when the indoor machine is installed according to the conventional situation and is always consistent with the length direction of the indoor machine of the air conditioner. The first direction slide bar is movable on a second direction slide bar, the first direction slide bar and the second direction slide bar being perpendicular. The first direction slide bar 1 provides a moving path in the horizontal direction for the sterilization assembly, the second direction slide bar 2 provides a moving path perpendicular to the horizontal direction for the sterilization assembly, and through the combination of the movement of the first direction slide bar 1 and the second direction slide bar 2, the photosensitizer sprayed by the photosensitizer spraying device 12 of the sterilization assembly and the exciting light emitted by the laser light source 11 can cover the whole area to be sterilized, namely, the indoor heat exchanger or the filter screen.

Since the area of the area to be sterilized is large, for example, the indoor heat exchanger or the filter screen occupies a large area, in order to enable the sterilization assembly with a small area to cover the whole area to be sterilized, the area to be sterilized of the air conditioner needs to be divided into at least S/K blocks, where S is the area of the indoor heat exchanger or the filter screen, and K is the area of the area to be sterilized, where S is the area of the area to be sterilized, where K is the area of the area to be sterilized, and S/K is 2, for example, the indoor heat exchanger is divided into a and B2 blocks, the photosensitizer injection device 12 is controlled to spray a predetermined photosensitizer to the first block a of the area to be sterilized of the air conditioner, and the photosensitizer and bacteria are in full contact after a first predetermined time, and in general, the photosensitizer and the bacteria can be in full contact in. Controlling the excitation light source 11 to emit excitation light with a predetermined wavelength to irradiate the first block A of the area to be sterilized of the air conditioner sprayed with the predetermined photosensitizer for a second preset time, wherein the irradiation time is related to the illumination intensity, for example, when the emission power is 1W, the illumination intensity is 50mW/cm2The sterilization of the first block A can basically meet the requirement after 60-90 seconds of irradiation of the exciting light. After the sterilization of the block A is finished, a second block B is still to be sterilized, the sterilization process is repeated for the block B, for example, the block B controls the motor to drive the sterilization component to move to the second block B of the area to be sterilized of the air conditioner, the photosensitizer spraying device 12 is controlled to spray a predetermined photosensitizer to the second block B of the area to be sterilized of the air conditioner, the photosensitizer is fully contacted with bacteria after 6-10 minutes, and the excitation light source 11 is controlled to emit excitation light with a predetermined wavelength to irradiate the second block B for 60-90 seconds; and after the sterilization of the area to be sterilized of the air conditioner is completed, controlling the sterilization assembly to return to the initial position, for example, after the sterilization of the last block B is completed, judging that the whole indoor heat exchanger or the filter is sterilized in a covering manner, and controlling the sterilization assembly to return to the initial position to wait for a next sterilization starting instruction.
