Abstract
The utility model discloses an electronic fresh-keeping and smell-removing device for refrigerator belonging to an air purifier. The electronic fresh-keeping and smell-removing device for refrigerator is characterized in that the 220V AC power supply is changed into the 3000V negative AC voltage through the voltage multiplying rectifier, and then the 3000V negative AC voltage is added on a high-efficiency discharge electrode to form a high voltage electric field. The air around the high-efficiency discharge electrode is ionized to form negative air ions and generate right amount of ozone, so the electronic fresh-keeping and smell-removing device for refrigerator can kill the bacterium in the air and in the surface of stowage in the refrigerator and remove the smell to keep the food fresh. The electronic fresh-keeping and smell-removing device for refrigerator can be used to match with the existing refrigerator, and the electronic fresh-keeping and smell-removing device for refrigerator can be directly arranged in the refrigerator when manufacturing.
Description
This utility model belongs to a kind of air cleaner, the particularly a kind of fridge freshness retaining odor eliminator that can remove stink and have bactericidal action.
The refrigerator odor eliminator that uses has following type at present, the one, the physisorption type bad-smell adsorber, it mainly is to absorb gas and moisture in the refrigerator by adsorbents such as active carbon, zeolites, but this class bad-smell adsorber does not have killing action to gas and the antibacterial in the moisture that is absorbed, and bad-smell adsorber itself is also smelly easily.The 2nd, the chemical reaction type bad-smell adsorber, its mainly be ferrum to be reactants such as chemicals, sulfur dioxide remove foul smell composition in the refrigerator by the method for chemical reaction, this class bad-smell adsorber can not be killed the antibacterial in the gas and moisture in the refrigerator, service life is also shorter.The 3rd, the disclosed a kind of refrigerator bad-smell adsorber of CN87102957A, it mainly is to adhere to antibacterial or mix into antibacterial on the air permeable wrapping of splendid attire adsorbent in the middle of adsorbent, direct kill bacteria and removal abnormal flavour, but the sterilization mode of this class bad-smell adsorber will could realize in the filtration by the air permeable wrapping thing, and the air permeable wrapping thing to adhere to germ-resistant technological requirement higher.Four is a kind of automatic deodorisers of electronics that are installed in the refrigerator of developing of Japan one tame electric company of in January, 1988 Beijing electronics newspaper report, its main feature is by fan the air in the refrigerator to be sucked deodoriser, on the electrode that pottery is made, add 2000 volts voltage, produce electrion, make oxygen ozonize in the air, because of the foul smell molecule generation chemical reaction in ozone molecule and the refrigerator, thereby the foul smell molecular concentration is descended, the ozone molecule that does not react titanium catalyst thin film adsorbs, and be reduced into oxygen, at last clear air is sent into each chamber of refrigerator again.Thereby reach the purpose of kill bacteria, removal stink.But its shortcoming is just can finish its work by fan, and discharging efficiency is not high, and power consumption is big, the cost height.
The purpose of this utility model is to provide a kind of negative aeroion that produces high concentration and an amount of ozone and the refrigerator electronic fresh-keeping odor eliminator of kill bacteria, removing stink.
Task of the present utility model is finished like this, with exchanging 220 volts of power supplys by many voltage multiplying rectifiers, obtain about 3000 volts negative dc voltage, the efficient discharge that is added in the discharge mechanism is extremely gone up, and forms high voltage electric field, and near the air of electrode is ionized, form negative aeroion, and produce an amount of ozone, because negative aeroion can purify air, delivered fresh such as fruit, vegetable there is the function that prolongs storage period.Ozone is a kind of strong oxidizer, can kill various antibacterials, mycete, and the various organic substances in the oxidation air are removed various abnormal flavour, stink effectively.
Advantage of the present utility model is: (1) can produce the antibacterial that high concentration negative aeroion and an amount of ozone are killed air and repertory surface in the refrigerator; (2) volume is little, and cost is low; (3) discharging efficiency is higher, and power consumption is little.
Below in conjunction with drawings and Examples this utility model is described specifically.
