Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.
The range hood purification method provided by the application can be applied to the application environment shown in figure 1. The purifying assembly is arranged in the range hood and used for purifying harmful bacteria in the range hood, and the purifying assembly is used for specifically acquiring the content of bacteria in the range hood; comparing the content of bacteria in the range hood with a preset threshold value of the content of bacteria; if the content of bacteria in the range hood exceeds a preset bacteria content threshold value, starting a plasma purification function; monitoring the content of bacteria in the range hood after the plasma purification function is started in real time; and when the content of bacteria in the range hood does not exceed the preset threshold value of the content of bacteria, the plasma purification function is closed. Specifically, the purification assembly may include a sensor to collect the bacterial content within the range hood, a plasma purification assembly to perform a plasma purification function, and a controller.
In one embodiment, as shown in fig. 2, the present application provides a method for purifying a range hood, the method comprising:
s100: and acquiring the content of bacteria in the range hood.
After the range hood normally works for a period of time, a large amount of oil stains are adsorbed in the range hood, and a large amount of harmful bacteria (viruses) are bred in the oil stains. Here, the content of bacteria in the range hood can be detected by a sensor. Optionally, the bacterial content at different positions in the range hood can be collected by a plurality of sensors which are distributed in the range hood.
S200: and comparing the content of bacteria in the range hood with a preset bacteria content threshold value.
The preset bacteria content threshold value is a preset value, and specifically, the bacteria content in the range hood can be analyzed through experimental data, historical data or expert database data and the like on the premise of not harming human health. The data supports remote setting and updating of the range hood manufacturer in the background. Further, can set up the predetermined bacterial content threshold value of different purification grades, different purification grades specifically include slight purification, standard purification and deep purification, and it is corresponding the first predetermined bacterial content threshold value, the second predetermined bacterial content threshold value and the third predetermined bacterial content threshold value that reduce in proper order respectively. Specifically, when the user side operates, a purification degree selection interface can be displayed on the range hood or a corresponding physical button is provided, the level corresponding to the purification of the range hood is determined in response to the user selection operation, for example, if the user presses the physical button for standard purification, the purification level of the range hood is the standard, and the preset bacteria content threshold is the corresponding second preset bacteria content threshold.
S300: and if the content of bacteria in the range hood exceeds a preset bacteria content threshold value, starting a plasma purification function.
If the content of bacteria in the range hood exceeds a preset bacteria content threshold value, it is indicated that the current bacterial content in the range hood seriously harms the health of a user, and the range hood needs to be cleaned immediately, and then the plasma purification function is started immediately. Specifically, the plasma purification function mainly includes two aspects of deodorization and sterilization, and can be realized by the plasma generating action device. Specifically, substances such as free radicals and ozone generated by the plasma generating device sterilize the interior of the range hood, free bacteria and viruses in the air in the range hood are killed by utilizing the property of extremely strong oxidizing property of the free radicals, and the ozone is slightly weak in oxidizing property but easy to diffuse and can kill bacteria and viruses attached to the accumulated surface of the oil stain; the copper ion deodorizing block is honeycomb-shaped, CuO and MnO2 nanoparticles are adhered to the surface of the copper ion deodorizing block, and low molecular aldehyde, ketone or carboxylic acid and other odor react with oxygen at normal temperature under the catalytic action to be degraded into CO2 and H2O.
S400: and monitoring the content of bacteria in the range hood after the plasma purification function is started in real time.
After the plasma purification function is started, the bacterial content in the range hood is continuously monitored, and the specific monitoring process is similar to the process of S100 acquiring the bacterial content in the range hood. By monitoring the content of bacteria in the range hood after the plasma purification function is started in real time, on one hand, whether the plasma purification function is effective or not, namely whether the number of bacteria in the range hood is effectively reduced or not can be judged after the plasma purification function is started; on the other hand, the monitoring is continued to ensure that the plasma cleaning function is stopped when the bacteria content in the range hood is reduced to a preset bacteria content threshold value subsequently.
S500: and when the content of bacteria in the range hood does not exceed the preset threshold value of the content of bacteria, the plasma purification function is closed.
When the content of bacteria in the range hood does not exceed the preset threshold value of the content of bacteria, the current content of bacteria in the range hood is reduced to a reasonable amount, the purification can be temporarily stopped, and the plasma purification function is closed at the moment, so that unnecessary resources are wasted.
According to the range hood purification method, the content of bacteria in the range hood is obtained; comparing the content of bacteria in the range hood with a preset threshold value of the content of bacteria; if the content of bacteria in the range hood exceeds a preset bacteria content threshold value, starting a plasma purification function; monitoring the content of bacteria in the range hood after the plasma purification function is started in real time; and when the content of bacteria in the range hood does not exceed the preset threshold value of the content of bacteria, the plasma purification function is closed. In the whole process, the bacteria content in the range hood is automatically detected, and when the bacteria content exceeds a preset bacteria content threshold value, the plasma purification function is started, the interior of the range hood is continuously purified until the bacteria content in the range hood is reduced to the preset bacteria content threshold value, so that the harmful bacteria in the range hood are purified.
In one embodiment, the range hood purification method further includes: and responding to the user operation to acquire the content of bacteria in the range hood.
In this embodiment, the user is also supported to manually start the range hood purification function. In an actual application scene, a user operates the range hood, presses a physical key/virtual key on the range hood for starting plasma purification, and the range hood starts a plasma purification function. Furthermore, the range hood can adopt the embodiment to automatically detect the content of bacteria in the range hood in the daily use process, if the content of bacteria in the range hood exceeds a preset threshold value of the content of bacteria, the plasma purification function is started, the mode can be adopted to clean harmful bacteria in the range hood normally when the range hood is electrified, but the harmful bacteria in the range hood can not be cleaned under the conditions of long-term business trip and outages and power failure of users, and a great amount of effective bacteria in the range hood breed in the period, when a user goes home and goes out, the range hood can be powered on, the plasma purification function starting button is pressed, the range hood responds to the user operation to start the purification function of the range hood, if the bacteria content exceeds the preset bacteria content threshold value, then the plasma purification function is started to kill the harmful bacteria bred in the range hood in the period of going out.
In one embodiment, obtaining the content of bacteria in the range hood comprises: when the range hood is detected to be shut down, the content of bacteria in the range hood is collected.
When the range hood works, strong suction and air flow are formed inside the range hood, the bacteria content in the range hood cannot be accurately collected in the environment, and plasma purification is not facilitated. Therefore, generally, in order to ensure effective plasma purification effect, it is necessary to start collecting the bacteria content in the range hood when detecting that the range hood is turned off. In practical application, when a user finishes using the range hood, the user presses the shutdown key, the fan of the range hood is closed, the content of bacteria in the range hood is collected at the moment, and if the content of the bacteria exceeds a preset threshold value of the content of the bacteria, the plasma purification function is started.
As shown in fig. 3, in one embodiment, after S500, the method further includes:
s600: starting the fan of the range hood, and closing after delaying preset time.
Some pairs of residual gas can be generated after the plasma purification treatment, after the plasma purification function is closed, the fan of the range hood is started again to discharge the residual gas, so that the influence on a user is avoided, and the fan is closed after a certain time delay. The preset time is a preset time, and can be specifically set according to actual needs, for example, 30 seconds, 1 minute, and the like can be set. In practical application, the plasma purification function can adopt ozone to kill bacteria and viruses in the air in the range hood, some ozone can be remained after the plasma purification is completed, the range hood fan is started at the moment, and the range hood fan is closed after 30 seconds of operation so as to discharge the hidden ozone. Unnecessary, can start the lowest grade with the fan, can also avoid noise interference user when reducing the energy consumption.
It should be understood that, although the steps in the flowcharts are shown in sequence as indicated by the arrows, the steps are not necessarily performed in sequence as indicated by the arrows. The steps are not performed in the exact order shown and described, and may be performed in other orders, unless explicitly stated otherwise. Moreover, at least a part of the steps in each of the flowcharts described above may include multiple steps or multiple stages, which are not necessarily performed at the same time, but may be performed at different times, and the order of performing the steps or stages is not necessarily sequential, but may be performed alternately or alternately with other steps or at least a part of the steps or stages in other steps.
As shown in fig. 4, the present application further provides a range hood purification system, comprising:
the acquisition module 100 is used for acquiring the content of bacteria in the range hood;
the comparison module 200 is used for comparing the content of bacteria in the range hood with a preset threshold value of the content of bacteria;
the purification module 300 is used for starting a plasma purification function when the content of bacteria in the range hood exceeds a preset bacteria content threshold;
