The present invention relates to an electronic deodorizer for a refrigerator, and in particular, to allow the deodorization of the refrigerator by ozone and anion generated by corona discharge and the fresh storage of food.

Conventional electron deodorizers, as shown in FIGS. 1 to 3, have a high voltage transformer 10 in the main body of the electronic deodorizer 2, an ozone generator 11 connected to the high voltage transformer 10, and ozone. Ozone generating unit 13 consisting of a rectifying tube 12 for increasing the reactivity of the odor to increase the deodorizing effect, a fan 14 installed in the main body 2 to introduce the odor in the refrigerator, and the first deodorized odor UV generation unit 17 consisting of an ultraviolet lamp 15 for generating ultraviolet rays for secondary deodorization, a blocking plate 16 for blocking ultraviolet rays, and a honeycomb shape for decomposing residual ozone after reacting with odor. The catalyst filter unit 19 for ozone removal comprised of the catalyst filter 18 of this invention is comprised.

In such a conventional apparatus, the ultraviolet rays emitted from the ultraviolet lamp 15 may generate ozone or decompose ozone depending on the wavelength band as a radio wave having a wavelength band of 10 Hz to 3800 Hz.

Ozone generation can be generated as the ozone generator 11 as shown in FIG. 2 and FIG. 5, wherein the discharge electrode 17b formed on the dielectric 17a is silk-screened using titanium or platinum, Inside the dielectric, the induction electrode 17c is silk-screened using titanium or the like to form an electric field by a high voltage applied between the discharge electrode 17b and the induction electrode 17c. The electric field direction is the discharge electrode 17b. Is formed as the induction electrode 17c, but since the dielectric 17a between the discharge electrode 17b and the induction electrode 17c has stronger insulating property than air, an electric field is formed around the discharge electrode 17b to generate ozone.

The ultraviolet rays can usually be generated by using ultraviolet lamps 15 as shown in FIGS. 2 and 3, the principle of which is to charge an argon gas or a helium gas in a quartz glass tube and a high potential difference between the anode and the cathode in the filling gas atmosphere. As it is generated, electrons are emitted from the cathode, which passes through the vacuum discharge tube and is accelerated to have high energy.

As these high-energy electrons pass through the gas molecules, they expel the electrons of the neutral molecules to make the gas molecules into cations instantaneously, but the cationized gas molecules attract electrons back to return to a stable state. The difference in energy is emitted to the light to emit ultraviolet light.

Ultraviolet rays adjusted to a wavelength of 254 μm by a vacuum or material of an electrode in a quartz tube have an energy of E = hc / λ according to the flank formula, so the energy is expressed in the formula of O ₃ + hc / λ → O ₂ + O ( h: flank constant, c: luminous flux, λ: wavelength).

Therefore, the intake air including the odor in the refrigerator sucked by the drive of the fan 14 by the principle as described above is mixed with the ozone emitted from the ozone generator 11 to form a turbulent flow through the rectifying plate 12 It is incorporated in a very good state to remove odors primarily.

In the process, the conventional malodors cause an oxidation reaction and change into an odorless gas.

At this time, the rectifying plate 12 is a fibrous filter as shown in FIG. 4, and serves to form a flow of the turbulent layer by increasing the contact time and contact rate of ozone and odor molecules.

Firstly, the intake air from which the odor has been removed is completely removed by the ultraviolet rays emitted from the ultraviolet lamp 15 while passing through the ultraviolet generation unit 17.

In this way, when the odor contained in the intake air passes through the ozone removal catalyst filter unit 19 while completely deodorized by the ozone generator 13 and the ultraviolet generator 17, it reacts with the odor, and any remaining residual Since ozone is completely decomposed by the catalytic filter 18, odorless clean air is supplied to the refrigerating chamber.

In addition, in order to store food freshly, a separate fresh storage vegetable compartment is conventionally set up, and as shown in FIG. When (4) inhales and sends it to the nitrogen air generator (8), the molecular sieve carbon (7) material in the interior selectively separates only the nitrogen air in the general air, so that the high concentration exiting the nitrogen air generator (8) is achieved. Nitrogen air was supplied into the vegetable compartment 3 so that the oxygen in the vegetable compartment 3 gradually became thin and the reported vegetables were oxidized slowly and the stored foods could be kept fresh longer.

The oxygen sensor 9 intermittently extracts air from the vegetable chamber 3 through the flow path tube 5a, checks the oxygen concentration in the vegetable chamber 3, and reaches a predetermined concentration (usually 5 to 10%) of the fresh storage device. It serves to stop operation.

Conventional electronic deodorizer is to remove odor by generating ozone with strong oxidizing power, so the internal components must be made of a strong ozone-resistant material, as well as to deteriorate food by the strong oxidation of ozone to remove odor. Ozone was adversely affected by prolonged exposure to humans or food.

In addition, the food freshness storage device of the conventional refrigerator comprises an air compressor (4), a nitrogen air generating unit (8), an oxygen sensor (9) and flow path pipes (5, 5a), and the configuration is complicated. If the flow pipes 5 and 5a are not tightly coupled so that there are no gaps, the fresh storage capacity of the food is not only degraded, but in order to maintain the freshness of the stored food in the refrigerator for a long time, the respiratory action of the conventional food itself is suppressed. Caesar only fell the effect.

This conventional technology is a storage of food, such as meat, fish and vegetables stored in the refrigerator or vegetable compartment of the refrigerator, freshness due to the self-respiration action, there is a problem in long-term storage, causing odors to shift the smell to other stored foods or There is another problem that reduces the freshness of the food by causing discoloration, and also because a separate vegetable room is required for fresh storage of food in the refrigerator, the amount of food that can be stored is limited depending on the capacity of the vegetable room. There is another problem that a mechanical device for the need to increase the material cost.

The present invention has a simple configuration to solve the above problems, easy to manufacture and apply, there is no mechanical impediment to noise, and the voltage applied to the electronic deodorizer for refrigerators currently being applied to the refrigerator at a high voltage of a high current DC Ozone generated by applying voltage removes odors in the refrigerator, and by suppressing the proliferation of microorganisms generated by respiratory action of stored foods in the refrigerator by negative ions generated simultaneously by applying high voltage pulse voltage, storage of odor and fresh food in the refrigerator It is an object of the present invention to provide an electronic deodorization device for a refrigerator which is possible at the same time.
