Detailed ways

In order to make the above objects, features and advantages of the present invention more clearly understood, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only used to explain the present invention, but not to limit the present invention.

FIG. 1 is a schematic flowchart of a control method of an ultraviolet sterilization module in an embodiment of the present invention. The method of FIG. 1 can be applied to an ultraviolet sterilization device, which can include a plurality of independently controlled ultraviolet sterilization modules, and the ultraviolet sterilization device can be applied to an indoor unit of an air conditioner, a fresh air system, an air purification system, and the like. The above methods include:

S102: Determine the number of activations of the ultraviolet sterilization module according to the current ambient temperature.

Since the sterilization performance of the UV sterilization module is greatly affected by the ambient temperature, the time required to achieve the same expected sterilization effect at different ambient temperatures is different. The ultraviolet sterilization device in this embodiment includes a plurality of independently controlled ultraviolet sterilization modules, so different numbers of ultraviolet sterilization modules can be controlled to work under different ambient temperatures, so as to achieve the same expected sterilization effect and meet the sterilization rate requirement.

After the sterilization function is turned on, the current ambient temperature can be obtained through devices such as sensors, and the number of UV sterilization modules turned on can be determined according to the current ambient temperature. Generally, the higher the current ambient temperature, the more the number of UV sterilization modules that need to be turned on. Optionally, a corresponding relationship between the current ambient temperature and the number of UV sterilization modules turned on is preset, and the number of turned on UV sterilization modules can be determined by querying the corresponding relationship.

S104, according to the number of openings and the remaining service life corresponding to each ultraviolet sterilization module, control to activate the target ultraviolet sterilization modules of the above-mentioned number of openings.

The remaining service life corresponding to the target ultraviolet sterilization module is greater than the remaining service life corresponding to other ultraviolet sterilization modules. For a plurality of ultraviolet sterilization modules, the one with a larger remaining service life is preferentially activated, and the activation quantity is the activation quantity obtained in the above steps.

In one embodiment, which ultraviolet sterilization modules are preferentially activated may be determined in a sorted manner, optionally, performed in the following manner:

A1, sort the remaining service life corresponding to each ultraviolet sterilization module from large to small, and obtain the sorting result.

A2, control to activate the target ultraviolet sterilization module, where the target ultraviolet sterilization module includes the number of ultraviolet sterilization modules that are turned on first in the sorting result. After sorting the remaining service life from large to small, start the ultraviolet sterilization modules corresponding to the above-mentioned number of openings in the order from large to small.

In another embodiment, which ultraviolet sterilization modules are preferentially activated may be determined by means of screening, optionally, performed in the following manner:

In B1, the maximum value of the remaining service life corresponding to each ultraviolet sterilization module is screened to obtain the target ultraviolet sterilization module. The target UV sterilization module includes the number of UV sterilization modules with the largest remaining service life turned on. First, screen out the UV sterilization module with the largest remaining service life among all the UV sterilization modules, and use the UV sterilization module as the target UV sterilization module; then, screen out the UV sterilization module with the largest remaining service life among all the remaining UV sterilization modules, and continue The ultraviolet sterilization module is used as the target ultraviolet sterilization module; and the number of ultraviolet sterilization modules corresponding to the above-mentioned number of openings is obtained by screening multiple times.

B2, control to start the target ultraviolet sterilization module.

During the actual operation of the UV sterilization device, each UV sterilization module is not turned on and off at the same time, and the remaining service life of each UV sterilization module is different. By starting the UV sterilization module with the larger remaining service life as the target UV sterilization module, it can balance The remaining service life of each UV sterilization module improves the uniformity of the service life of each UV sterilization module.

Usually, all UV sterilization modules need to be installed and disassembled together. If the remaining service life of each UV sterilization module is too different, when the remaining service life of one UV sterilization module is zero, there may be other UV sterilization modules. If it is not replaced, the above-mentioned UV sterilization module with zero remaining service life cannot perform the sterilization function. In this embodiment, by controlling the UV sterilization module with a larger remaining service life to be activated preferentially, it is possible to achieve an approximately equal service life of each UV sterilization module.

Specifically, the remaining service life may be the difference between the design life and the accumulated opening time, or the remaining service life may be the ratio of the difference and the design life.

Considering that the longer the cumulative turn-on time of the UV sterilization module, the worse the sterilization effect. Therefore, it is necessary to increase the turn-on time accordingly. The turn-on time of the UV sterilization module can be determined based on the remaining service life of the UV sterilization module. Optionally, do as follows:

First, according to the remaining service life corresponding to the target ultraviolet sterilization module, the on-time of the target ultraviolet sterilization module is determined. The opening time is negatively correlated with the remaining service life corresponding to the target UV sterilization module. The longer the remaining service life corresponding to the target UV sterilization module, the shorter the opening time, and the shorter the remaining service life corresponding to the target UV sterilization module, the longer the opening time. long.

It can be understood that the ON duration of each target UV sterilization module can be determined based on the remaining service life corresponding to each target UV sterilization module, that is to say, the ON duration of each target UV sterilization module can be different; it can also be based on the remaining usage corresponding to each target UV sterilization module. The minimum remaining service life in the service life is used to determine its turn-on time, that is to say, the turn-on time of each target UV sterilization module is determined based on the minimum remaining service life, and the turn-on time of each target UV sterilization module is the same; The maximum remaining service life or the average remaining service life of the remaining service life corresponding to the sterilization module determines its opening time, and the opening time of each target ultraviolet sterilization module is the same.

Secondly, the target ultraviolet sterilization module with the above-mentioned activation quantity is controlled to start and run for the corresponding activation time. The number of target ultraviolet sterilization modules corresponding to the above-mentioned number of activations can be controlled to be activated until the running duration of each target ultraviolet sterilization module reaches the above-mentioned activation duration.

On the basis of the above method, this embodiment also provides the function of real-time monitoring of service life and a prompt for replacement. If the remaining service life of the ultraviolet sterilization module is less than or equal to zero, all ultraviolet sterilization modules are controlled to start up, and/or a prompt message for replacement is output. . When the remaining service life is less than or equal to zero, it means that the cumulative opening time of the UV sterilization module is equal to or greater than the design life of the UV sterilization module. At this time, in order to maximize the sterilization effect, all UV sterilization modules can be controlled to start, and/or, output UV sterilization A message that the module needs to be replaced.

In order for the user to have an intuitive understanding of the service life of the ultraviolet sterilization module, the above remaining service life can be displayed when the sterilization function is turned on or off. It can be understood that the remaining service life may be one remaining service life corresponding to all the ultraviolet sterilization modules, or may be a plurality of remaining service lives corresponding to each ultraviolet sterilization module. The remaining service life corresponding to all the ultraviolet sterilization modules may be one of the minimum remaining service life, the maximum remaining service life or the average remaining service life corresponding to all the ultraviolet sterilization modules.
