For those skilled in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

Referring first to FIG. 1 , wherein FIG. 1 is a schematic structural view of the indoor unit of the air conditioner of the present invention.

As shown in Figure 1, the air conditioner of the present invention includes an indoor unit, and the indoor unit includes a housing 1, a deflector 2 and a controller (not shown in the figure), and the air conditioner of the present invention also includes a germicidal lamp 3, a germicidal lamp 3 is arranged in the air duct of the casing 1, and the controller can control the germicidal lamp 3 to start or stop.

During the operation of the air conditioner, the controller can control the germicidal lamp 3 to turn on, so as to sterilize the airflow entering the housing 1, so as to make the airflow discharged from the indoor unit cleaner and safer.

It should be noted that the germicidal lamp 3 may be an infrared lamp or an ultraviolet lamp, and of course, it is preferably an ultraviolet lamp.

The present invention also provides a kind of sterilization control method for air conditioner, as shown in Figure 2, the sterilization control method of the present invention comprises the following steps:

S100: Obtain the light intensity in the room.

During the operation of the air conditioner, if a sterilization instruction from the user is received, the controller can control the germicidal lamp to start running, or, during the operation of the air conditioner, the air conditioner can also automatically judge whether the sterilization conditions are met. In the sterilizing condition, the germicidal lamp is activated.

Wherein, the sterilization condition can be set such that the time interval after the last operation of the suicide germicidal lamp is greater than or equal to the preset time, for example, the preset time is 24 hours, and after the germicidal lamp finishes running, the controller records the current time, For example, if the current time is 10:00 am on June 1, the next sterilization time will be 24 hours later, that is, 10:00 am on June 2. When the time reaches or exceeds 10:00 am on June 2, that is, When the interval time is greater than or equal to 24 hours, it means that the sterilization conditions are met; or, the sterilization conditions can also be set such that the running time of the air conditioner after the last operation of the suicide germ lamp is greater than or equal to the preset time, etc., this flexible All adjustments and changes without departing from the principle and scope of the present invention should be limited within the protection scope of the present invention.

Certainly, preferably, the sterilization condition is set such that the time interval after the last operation of the suicide germ lamp is greater than or equal to the preset time. Wherein, those skilled in the art can flexibly set the specific value of the preset time according to specific situations.

During the operation of the germicidal lamp, to obtain the light intensity in the room, a light sensor can be installed on the housing of the indoor unit or other positions in the room. For example, as shown in Figure 1, the housing 1 of the indoor unit A light sensor is installed on the top of the light sensor, which is denoted as the first light sensor 4, and the light intensity in the room can be collected by the first light sensor 4, and the first light sensor 4 is connected with the controller of the air conditioner in order to be able to collect the light intensity. The data is transmitted to the controller in a timely manner.

S200: Acquire the running brightness corresponding to the light intensity.

Wherein, after obtaining the light intensity in the room, the running brightness corresponding to the light intensity may be obtained through formulas, comparison tables, and the like. Exemplarily, a running brightness comparison table is pre-stored in the controller of the air conditioner. As shown in FIG. The light interval, the operating brightness also includes three levels, from weak to strong are low brightness, medium brightness and strong brightness, among which, low brightness corresponds to the first light interval, medium brightness corresponds to the second light interval, and strong brightness corresponds to the second light interval. Corresponding to the third ray interval.

S300: Make the germicidal lamp run according to the running brightness.

After obtaining the operating brightness corresponding to the light intensity in the room, make the germicidal lamp operate according to the operating brightness. By matching the operating brightness of the germicidal lamp to the light intensity in the room, the impact of light pollution can be reduced and the user experience can be improved.

It should be noted that during the operation of the germicidal lamp, if the light intensity in the room changes, the operating brightness of the germicidal lamp will also change accordingly, that is, during the operation of the germicidal lamp, the operating brightness of the germicidal lamp should always The light intensity in the room is suitable.

In addition, it should be noted that a sterilizing time can be set, and when the running time of the sterilizing lamp reaches the sterilizing time, the germicidal lamp stops running.

Preferably, as shown in Figure 2, the sterilization control method of the present invention also includes the following steps:

S400: Obtain the brightness in the housing.

After the germicidal lamp starts to run, obtain the brightness in the housing. Exemplarily, as shown in FIG. At the position where the lamp 3 can be irradiated, the brightness in the housing 1 can be collected by the second light sensor 5, and the second light sensor 5 is connected with the controller of the air conditioner in communication, so that the collected data can be transmitted in time to the controller.

S500: Obtain the opening angle of the air deflector of the indoor unit.

S600: Get preset brightness corresponding to light intensity and opening angle.

Wherein, after obtaining the light intensity in the room and the opening angle of the wind deflector, the preset brightness corresponding to the light intensity and the opening angle can be obtained through a formula, a comparison table, and the like.

Exemplarily, as shown in Figure 5, three light intervals can be set for the light intensity, which are the first light interval, the second light interval and the third light interval according to the light intensity from weak to strong, and the opening of the wind deflector The angles include 30 degrees, 45 degrees and 60 degrees. According to the above three light intervals and opening angles, a preset brightness comparison table is made. From the comparison table, it can be seen that the preset brightness has five values, from weak to strong. A1, A2, A3, A4, A5. After obtaining the light intensity and the opening angle of the wind deflector, the corresponding preset brightness can be obtained through the comparison table.

It should be noted that on the surface, the preset brightness is determined according to the light intensity in the room and the opening angle of the wind deflector, but in fact, there are three factors that affect the preset brightness, namely, the light intensity in the room, the opening angle of the wind deflector. The opening angle of the air plate and the operating brightness of the germicidal lamp. Since the operating brightness of the germicidal lamp corresponds to the light intensity in the room, the preset brightness comparison table can only include the light intensity in the room and the opening of the air deflector Angle of these two factors. However, when setting each specific value of the preset brightness, the influence of the operating brightness of the germicidal lamp must be taken into consideration.

Exemplarily, when determining the specific value of A1, the light intensity in the room is in the first light interval, the opening angle of the wind deflector is 30 degrees, and the operating brightness of the germicidal lamp is low brightness corresponding to the first light interval, The specific value of the brightness in the housing collected at this time is set as A1.

In addition, it should be noted that in practical applications, those skilled in the art can set the specific values of the preset brightness in the preset brightness comparison table for different types of germicidal lamps through experiments.

S700: Selectively adjust the brightness of the germicidal lamp according to the brightness in the housing and the preset brightness.

The brightness in the casing is the actual brightness value collected by the light sensor, and the preset brightness is the light intensity in the room at this time, the opening angle of the air deflector and the operating brightness of the germicidal lamp (which is different from that in the room) According to these two values, it can be judged whether the germicidal lamp at this time is operating according to the operating brightness (operating brightness corresponding to the light intensity in the room), if this When the germicidal lamp is not running according to the operating brightness (operating brightness corresponding to the light intensity in the room), the brightness of the germicidal lamp can be adjusted so that the brightness of the germicidal lamp can be adjusted to match the light intensity in the room The matching brightness, through such a setting, can ensure that the actual brightness of the germicidal lamp matches the light intensity in the room, and avoid the situation that the actual brightness of the germicidal lamp is too high.

It should be noted that after obtaining the brightness in the casing and the preset brightness, the two can be directly compared, and then the brightness of the germicidal lamp can be selectively adjusted according to the comparison result, or the difference between the two can also be calculated. difference, and then selectively adjust the brightness of the germicidal lamp according to the size of the difference, etc. This flexible adjustment and change does not deviate from the principle and scope of the present invention, and should be limited within the protection scope of the present invention .

The technical solution of the present invention will be described in detail below in combination with a preferred embodiment.

As shown in Figure 3, the sterilization control method of the present invention comprises the following steps:

S100: Obtain the light intensity in the room.

S200: Acquire the running brightness corresponding to the light intensity.

S300: Make the germicidal lamp run according to the running brightness.

S400: Obtain the brightness in the housing.

S500: Obtain the opening angle of the air deflector of the indoor unit.

S600: Get preset brightness corresponding to light intensity and opening angle.

It should be noted that, the specific content of steps S100 to S600 has been introduced in detail above, and will not be described one by one here, and the content of step S700 will be mainly introduced in detail below.

As shown in FIG. 3 , the step of "selectively adjusting the brightness of the germicidal lamp according to the brightness in the casing and the preset brightness" specifically includes S701 to S703.

S701: Calculate the difference between the brightness in the casing and the preset brightness.

Wherein, the difference=|luminance in the casing−preset brightness|.

S702: Determine whether the difference is greater than a first preset value.

After calculating the difference between the brightness in the casing and the preset brightness, the difference is compared with the first preset value, and the brightness of the germicidal lamp is selectively adjusted according to the comparison result. Specifically, if the difference is less than or equal to the first preset value, it means that the brightness in the casing is relatively close to the preset brightness, further indicating that the actual brightness of the germicidal lamp and the operating brightness (the operating brightness corresponding to the light intensity in the room) Brightness) is relatively close, in this case, there is no need to adjust the brightness of the germicidal lamp, just go back to step S100; on the contrary, if the difference is greater than the first preset value, it means that the brightness in the housing is different from the preset brightness is larger, which further indicates that the actual brightness of the germicidal lamp is quite different from the running brightness (the running brightness corresponding to the light intensity in the room). In this case, step S703 is executed next.

It should be noted that in practical applications, those skilled in the art can flexibly set the specific value of the first preset value based on experiments or experience, as long as the critical point determined by the first preset value can determine the actual value of the germicidal lamp. Whether there is a large difference between the brightness and the operating brightness (the operating brightness corresponding to the light intensity in the room) is enough.

S703: Adjust the brightness of the germicidal lamp.

When the difference between the brightness in the casing and the preset brightness is greater than the first preset value, the brightness of the germicidal lamp needs to be adjusted. Specifically, compare the brightness in the housing with the preset brightness, if the brightness in the housing is greater than the preset brightness, then turn down the brightness of the germicidal lamp; otherwise, if the brightness in the housing is lower than the preset brightness, then turn the The brightness of the lamp is turned up.

It should be noted that the adjustment range of the brightness of the germicidal lamp can be a fixed value, or can be determined according to the difference between the brightness in the housing and the preset brightness. This flexible adjustment and change does not deviate from the principle of the present invention and scope, should be limited within the protection scope of the present invention.

In addition, it should be noted that after step S703 is executed, step S400 may be returned, or step S100 may be returned directly, and such flexible adjustments and changes do not deviate from the principle and scope of the present invention. Should be limited within the protection scope of the present invention.

Preferably, the sterilization control method of the present invention further includes: when the difference between the brightness in the casing and the preset brightness is greater than the first preset value, and the brightness in the casing is smaller than the preset brightness, setting the difference to Comparing with the second preset value; according to the comparison result, selectively causing the air conditioner to issue a prompt message of germicidal lamp failure.

When the brightness in the casing is less than the preset brightness and the difference is large, the difference between the two is further compared with the second preset value, wherein the second preset value is greater than the first preset value, and according to the comparison result It can judge whether the germicidal lamp is faulty, and when the germicidal lamp is faulty, the air conditioner can send a prompt message of germicidal lamp fault, so as to remind the user to replace or repair the germicidal lamp in time.

It should be noted that in practical applications, those skilled in the art can flexibly set the specific value of the second preset value according to experiments or experience, as long as the critical point determined by the second preset value can determine whether the germicidal lamp appears failure.

Preferably, the step of "selectively causing the air conditioner to issue a prompt message of germicidal lamp failure according to the comparison result" specifically includes: if the difference is less than the second preset value, it means that although the current brightness of the germicidal lamp is quite different from the operating brightness , but there is no fault, there is no need to make the air conditioner send a prompt message of germicidal lamp failure; on the contrary, if the difference is greater than or equal to the second preset value, it means that the germicidal lamp has failed and is not on. In this case , so that the air conditioner sends out a prompt message of germicidal lamp failure, so as to prompt the user to repair or replace the germicidal lamp in time.

It should be noted that in practical applications, a sound device can be installed on the indoor unit. When the germicidal lamp fails, the sound device (such as a buzzer, voice announcer, etc.) will sound to remind the user that the germicidal lamp has failed, or , It is also possible to install an indicator light on the indoor unit. When the germicidal lamp fails, the indicator light displays the fault color to prompt the user that the germicidal lamp fails. Or, the combination of the indicator light and the sound device jointly prompts the user that the germicidal lamp fails. etc. Those skilled in the art can flexibly set specific prompting methods in practical applications. Such adjustments and changes to the prompting methods do not deviate from the principle and scope of the present invention, and should be limited within the protection scope of the present invention.

Preferably, the sterilization control method of the present invention further includes: comparing the light intensity with a preset intensity; if the light intensity is less than the preset intensity, turning off the germicidal lamp.

When the light intensity in the room is less than the preset intensity, it means that the light in the room is very weak, and the user is likely to be resting. In this case, turning off the germicidal lamp can avoid affecting the user’s rest and further improve the user experience. .
