When the weight detected by the weight detecting part 80 is greater than the first preset weight or the second preset weight is increased and more than the first preset weight, the sterilization mode is started; when the weight detected by the weight detecting part 80 is less than or equal to the preset weight or increases below a second preset weight, the sterilization mode is turned off. The weight detection part 80 is a weight sensor, and is convenient to use and low in cost.
In this embodiment, the items to be disinfected are dishware, in which case the disinfection apparatus is a disinfection cabinet. Of course, the item to be disinfected may also be an item which he needs to disinfect.
In this embodiment, the disinfection cabinet has three modes, which are respectively an air purification mode, a disinfection mode and an automatic mode, as follows:
when the user selects the air purification mode, the distance between the generating electrode 21 and the collector 22 is 30mm, and the generating electrode 21 is connected with 18kV voltage, so that the purification effect is ensured, the energy consumption and ozone pollution are greatly reduced, and the air purification capacity is enhanced.
When the user selects the disinfection mode, the fan runs at the lowest gear, the generating electrode 21 and the collecting electrode 22 are pulled down by the driving mechanism between the generating electrode 21 and the collecting electrode 22 for a short distance from the original 30mm to 10mm, and meanwhile, the generating electrode 21 is connected with the voltage of 35kV to generate plasma and ozone with higher concentration, so that the rapid sterilization and disinfection of the target object are realized.
When the user selects the automatic mode, the automatic mode is respectively an air purification mode and a disinfection mode, the dust sensor detects the dust concentration (namely the particle concentration) in the current operating environment of the disinfection cabinet, and when the dust concentration is detected to be more than or equal to 35 mu g/m3When the dust removal system is used, the purification mode is automatically started, the fan operates at the highest gear, the dust is rapidly purified, and when the concentration of the indoor dust is lower than 35 mu g/m3When the system is in the normal state, the purification mode is automatically closed; weight sensor detects porous supporter's weight, and when it detected that weight increases 1Kg and above, the disinfection mode was opened automatically, and the fan is at the lowest grade operation, realizes high-efficient disinfection of disinfecting through the plasma of high concentration and ozone.
Wherein, the lowest gear and the highest gear respectively mean that the rotating speed of the fan is at the lowest rotating speed and the highest rotating speed.
The disinfection cabinet capable of efficiently purifying air adopts high-concentration plasma and ozone to disinfect and purify, on one hand, the disinfection cabinet can meet the requirement of fast degerming of a user, also can intelligently switch disinfection modes, quickly kill all microorganisms such as bacteria and viruses, realize fast disinfection and sterilization, completely remove pollutants efficiently and in a long-acting manner, has stronger disinfection and sterilization capacity than the disinfection cabinet which only uses ozone in the prior art, and greatly enhances the user experience of household appliances; on the other hand can satisfy the requirement that the user removed dust fast, plays quick air-purifying's effect, purifies indoor air, really a tractor serves several purposes.
From the above description, it can be seen that the above-described embodiments of the present invention achieve the following technical effects:
1. use two electrodes as purifying part and disinfection part, can produce plasma and ozone of different concentrations according to different mode intelligence, not only realize air-purifying, can regard as air purifier, really kill the bacterium in addition, play sterile effect, realize the high-efficient disinfection of disinfecting, can regard as the sterilizer, the function is more excellent, carry out more efficient processing to the air, the throughput is stronger, the integration level is higher, realize a tractor serves several purposes, the effectual problem of having solved single function domestic appliance idle time length and rate of utilization not high.
2. The generator and/or the collector are driven to move by the driving mechanism, and compared with the purification mode, the higher the voltage is, the closer the distance between the generator and the collector is, the higher the plasma concentration and the ozone concentration are, and the more rapid and efficient sterilization and disinfection are realized.
3. The disinfection cabinet has an automatic mode, so that the operation steps of a user are reduced, and the intelligent degree is higher.
It should be understood that the above examples are only for clarity of illustration and are not intended to limit the embodiments. Other variations and modifications will be apparent to persons skilled in the art in light of the above description. And are neither required nor exhaustive of all embodiments. And obvious variations or modifications therefrom are within the scope of the invention.
