The user sends the prompt information of lack of liquid, so that the user can replenish the sterilizing liquid in the liquid storage tank 2 in time to avoid affecting the next sterilization.

Based on the above air conditioner, the present invention also provides a sterilization control method for the air conditioner.

The sterilization control method of the air conditioner of the present invention will be described in detail below with reference to FIG. 3 and FIG. 4 . 3 is a flowchart of the sterilization control method of the air conditioner of the present invention; FIG. 4 is a flowchart of an embodiment of the sterilization control method of the air conditioner of the present invention.

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

run the fan; obtain the rotation speed of the fan; obtain the injection speed corresponding to the rotation speed of the fan; run the sterilization device and spray according to the injection speed.

When the fan runs at a low wind speed, the spray speed of the sterilization device can be reduced. Exemplarily, the spray volume of the sprayer can be adjusted by an electronic control valve to be adapted to the wind speed at the air outlet. When the fan runs at a high wind speed , the injection speed of the sterilization device can be increased. Exemplarily, the injection volume of the sprayer can be increased through the electronic control valve to adapt to the wind speed at the air outlet, that is, the injection speed of the sterilization device is proportional to the rotational speed of the fan. By setting in this way, it is possible to avoid the situation that high wind speed corresponds to slow spray or low wind speed corresponds to high speed spray, so that the spray speed of the sterilization device is adapted to the wind speed, which is conducive to the full diffusion of the mist-like sterilant in the room to ensure that the room Bactericidal effect.

If the rotation speed of the fan is divided into 5 gears, the injection speed of the sterilization device is also divided into 5 gears, and if the rotational speed of the fan is divided into 3 gears, the injection speed of the sterilization device is also divided into 3 gears.

Preferably, the air conditioner has multiple sterilization modes. As shown in FIG. 4 , the sterilization control method further includes: acquiring an instruction for a user to select a sterilization mode; acquiring a sterilization mode corresponding to the instruction; acquiring a fan speed corresponding to the sterilization mode ; Make the fan run according to the fan speed; among them, the fan speed of each sterilization mode is different.

Exemplarily, the air conditioner has three sterilization modes, a fast sterilization mode, a standard sterilization mode, and a slow sterilization mode, wherein the fan speed in the fast sterilization mode is the highest, corresponding to the high-end speed, and the fan speed in the standard sterilization mode is medium, corresponding to the mid-range. Speed; the fan speed in the slow sterilization mode is the lowest, corresponding to the low speed.

After obtaining the instruction for the user to select the sterilization mode, if the user instructs the selected fast sterilization mode, the fan will run at a high-speed wind speed, and correspondingly, the sterilization device is made to spray at a high speed. If the user instructs the selected standard sterilization mode, then Make the fan run at the mid-speed wind speed, and correspondingly, make the sterilization device spray at the medium speed. If the slow sterilization mode is selected by the user's instruction, make the fan run at the low-speed wind speed, and correspondingly, make the sterilization device spray at the slow speed.

Preferably, the sterilization control method further includes: obtaining the time when the user returns home without obtaining an instruction; obtaining the area of the room; determining according to the time when the user returns home, the area of the room, and the injection speed of each sterilization mode Sterilization mode.

Sometimes the user does not select the sterilization mode, in this case, the air conditioner can obtain the user's home time and room area, and according to the user's home time, the room area and the spray of each sterilization mode. speed to determine which sterilization mode to perform.

It should be noted that, the air conditioner can be made to send inquiry information to the user's mobile terminal (such as a mobile phone) to inquire the time when the user returns home, and the time when the user returns home can be determined according to the information replied by the user; or, the air conditioner can also be made to record The user's life law, the time when the user goes home is obtained according to the user's life law, exemplarily, a camera can be installed in the room, and the camera can communicate with the controller of the air conditioner, and the user's life law can be recorded through the camera, Record the approximate time when the user goes home every day from Monday to Sunday. If the user does not select the sterilization mode, the time when the user goes home can be obtained according to the user's life rules; etc., of course, preferably by asking the user way to get the time when the user goes home.

It should also be noted that when installing the air conditioner, the installation staff can directly pre-store the area of the room in the controller of the air conditioner. If the user does not select the sterilization mode, the area of the room can be directly retrieved. ; Alternatively, a camera can also be installed on the air conditioner, the image of the room can be obtained through the camera, and the area of the room can be roughly calculated according to the image of the room, etc. Of course, it is preferable to store the area of the room directly in the in the controller of the air conditioner.

Preferably, the step of “determining the sterilization mode according to the time when the user goes home, the area of the room and the injection speed of each sterilization mode” specifically includes: calculating the required sterilization time according to the area of the room and the injection speed of the sterilization mode; judging the sterilization time Whether the time is longer than the time for the user to go home; perform the above steps in order of the injection speed from slow to fast. When the sterilization time required for the sterilization mode is not greater than the time for the user to go home, make the air conditioner execute the sterilization mode.

After obtaining the time when the user goes home and the area of the room, you can first calculate the required sterilization time according to the area of the room and the spray speed of the slow sterilization mode. Specifically, according to the area of the room, you can know how much to spray. Only the sterilant can meet the sterilization requirements, that is, the total amount of the sterilant to be sprayed can be obtained according to the area of the room, and the required sterilization time can be calculated according to the total amount of the sterilant and the injection speed.

If the sterilization time required by the slow sterilization mode is not greater than the time for the user to go home, the air conditioner can be directly executed in the slow sterilization mode. If the sterilization time required by the slow sterilization mode is greater than the time for the user to go home, the slow In the quick sterilization mode, continue to calculate the sterilization time required by the standard sterilization mode. If the sterilization time required by the standard sterilization mode is not greater than the time for the user to go home, the air conditioner can be directly executed in the standard sterilization mode. If the sterilization time required by the standard sterilization mode If the sterilization time required by the quick sterilization mode is greater than the time for the user to go home, the standard sterilization mode cannot be executed, and the sterilization time required by the quick sterilization mode continues to be calculated. Yes, if the sterilization time required by the quick sterilization mode is longer than the time it takes for the user to go home, the sterilization task will be canceled.

That is to say, when the sterilization time of multiple sterilization modes meets the requirements, it is preferable to execute the sterilization mode with the required sterilization time longer, and the sterilization effect on the room is better.

Preferably, the sterilization control method of the present invention further includes: during the operation of the sterilization device, if it is detected that the electronic lock of the door of the room is unlocked, stopping the operation of the sterilization device, and selectively allowing the room according to the sterilization process. The door opens.

In the process of sterilizing the room, a large amount of sterilant needs to be sprayed into the room. Therefore, in the process of sterilizing the room, the user is not suitable to stay in the room. During the process of sterilizing the room, however, during the process of sterilizing the room, the user may suddenly return home, and if the user is allowed to enter the room rashly, it may cause certain damage to the user's body.

Therefore, the electronic lock of the door is made to communicate with the controller of the air conditioner. During the process of sterilizing the room, if the electronic lock of the door is unlocked, it means that the user has returned, and the electronic lock sends a signal to the controller, and the controller First control the sterilization device to stop running, no longer spray the sterilant, and selectively allow the door to open according to the sterilization process.

It should be noted that two unlocking commands can be set for the electronic lock of the door. The user can unlock the first unlocking command through fingerprint or password, and the second unlocking command is controlled by the controller of the air conditioner. The lock only activates one unlocking command, that is, the first unlocking command. In this case, as long as the user enters the correct fingerprint or password, the electronic lock can be unlocked and the door can be opened; however, in the process of sterilizing the room In this case, the user can only unlock the first unlock command by entering the correct fingerprint or password, but the electronic lock cannot be fully unlocked. The controller of the air conditioner needs to send the second unlock command. The unlocking instruction can completely unlock the electronic lock to open the door, so that during the process of sterilizing the room, the controller of the air conditioner can selectively allow the door to be opened according to the sterilization process.

Preferably, the step of "selectively allowing the door to open according to the sterilization process" specifically includes: comparing the running time of the sterilization device with a preset time; if the running time is less than the preset time, allowing the door to open; If the time is greater than or equal to the preset time, the door is not allowed to open.

When the running time of the sterilization device is less than the preset time, it means that the running time of the sterilization device is short, and the sterilant sprayed into the room is not much. In this case, the door can be allowed to open to allow the user to enter the room; otherwise, When the operation time of the sterilization device is greater than or equal to the preset time, it means that the operation time of the sterilization device is relatively long, and more sterilant is sprayed into the room. In this case, the door is not allowed to open, and users are not allowed to enter the room. , to prevent users from entering the room and causing damage to their bodies.

It should be noted that in practical applications, those skilled in the art can flexibly set the specific value of the preset time according to experiments or experience, as long as the critical point determined by the preset time can determine that the sterilant sprayed by the sterilization device will not be effective. The user can cause damage. In addition, when the air conditioner is provided with multiple sterilization modes, the specific value of the preset time corresponding to each sterilization mode can be set according to the injection speed of the sterilization device in each sterilization mode.

Preferably, the sterilization control method of the present invention further comprises: in the case that the door is not allowed to be opened, when the number of times the electronic lock is unlocked reaches a preset number of times, allowing the door to be opened. Exemplarily, the preset number of times is 3. In the case where the door is not allowed to be opened, if the user unlocks the electronic lock 3 times through fingerprints or passwords, it means that the user may have to enter the room in an emergency. The device sends a second unlock command to the electronic lock, allowing the door to open.

It should be noted that after the user is allowed to enter the room, the air conditioner can be made to issue a voice prompt to inform the user that the room is being sterilized, and the user is requested to leave the room as soon as possible.

It should also be noted that, during the operation of the sterilization device, if it is detected that the electronic lock of the door of the room is unlocked, the door can also be selectively allowed to open according to the concentration of the sterilant in the room.

Specifically, the step of “selectively allowing the door to open according to the concentration of the bactericide in the room” specifically includes: obtaining the concentration value of the bactericide in the room; comparing the concentration value with a preset value; if the concentration value If the concentration is less than the preset value, the door is allowed to open; if the concentration value is greater than or equal to the preset value, the door is not allowed to open.

A biocide concentration detection sensor can be set up in the room, and the biocide concentration detection sensor can communicate with the controller of the air conditioner. Set the value for comparison. When the concentration value is less than the preset value, it means that the concentration of the bactericide in the room is low. In this case, the door can be allowed to open to allow the user to enter the room; on the contrary, when the concentration value is greater than or equal to the preset value. When the value is set, it means that the concentration of the bactericide in the room is high. In this case, the door is not allowed to be opened, and the user is not allowed to enter the room.

It should be noted that in practical applications, those skilled in the art can flexibly set the specific value of the preset value according to experiments or experience, as long as the critical point determined by the preset value can determine that the bactericide in the room will not affect the user. Inflict damage.

Preferably, the sterilization control method of the present invention further includes: during the operation of the sterilization device, if a person is detected in the room, stopping the sterilization device from running.
