Description

Sterilization and deodorization of refrigerators and refrigerators {REFRIGERATOR AND DEORDERIZING METHOD THEREOF}

The present invention relates to a refrigerator, and more particularly, to a refrigerator and a method of deodorizing the refrigerator compartment for preventing the smell of food stored in the refrigerator or freezer compartment, and effectively sterilizing bacteria in the refrigerator compartment or freezer compartment.

Recent changes in consumption patterns have led many people to buy large amounts of food at large supermarkets rather than buy them at supermarkets nearby and cook them in a refrigerator or freezer for a long time.

Accordingly, as the storage period of food or food stored in the refrigerator becomes longer, the problem of smell of food or deterioration of food in the refrigerator has been seriously raised.

In other words, there is an urgent need for a method of minimizing damage while keeping food or ingredients in a refrigerator in a odorless state for a long time.

The present invention is comfortable by preventing the smell of food or ingredients stored in the freezer compartment or the refrigerating compartment of the refrigerator (hereinafter, referred to as the "cold compartment" in the freezer compartment and the refrigerating compartment together) including the claims. It is an object of the present invention to provide a sterilization deodorization method of a refrigerator and a refrigerating compartment that implements a refrigerating compartment environment.

In addition, another object of the present invention is to sterilize bacteria, molds, and the like, which are propagated in the refrigerating chamber, to provide a refrigerated environment for a clean and hygienic refrigerator, and to allow food and the like to be refrigerated for longer periods of time.

The present invention is to achieve the object as described above, the main body to form a closed space selectively with the outside by opening and closing the door; An evaporator for cooling the surrounding air; A cold air passage communicating the evaporator and the sealed space; A blower for forcibly transferring the cold air around the evaporator to the sealed space; A container containing water containing chlorine; An electrode part installed so that the positive electrode part and the negative electrode part face each other while being immersed in water of the container; A power supply unit supplying power to the electrode unit; A feeder for supplying sterilizing water containing residual chlorine containing hypochlorous acid generated by electrolysis of the electrode portion to the refrigerating compartment; It provides a refrigerator having a deodorizing sterilization performance, characterized in that configured to include.

It simply produces sterilized water containing residual chlorine, such as hypochlorous acid, which has high sterilizing power and is harmless to humans by electrolysis using water containing chlorine in the container, and then sprays, sprays or sprays the sterilized water into the refrigerating chamber. In order to provide a hygienic refrigerating environment by supplying by discharging, the odor in the refrigerating compartment is removed, and at the same time, bacteria and molds inhabiting the refrigerating compartment are removed with high sterilizing power.

At this time, the feeder is supplied while the sterilizing water is sprayed into the sealed space by supplying the sterilizing water to the cold air passage. Through this, even if the sterilizing water is not sprayed directly into the refrigerating chamber, the sterilizing water piggybacks on the flow of cold air to reach every corner of the refrigerating chamber through the cold air supply flow path, and thus the deodorizing effect and the sterilizing effect can be realized with a simple configuration.

The feeder is formed as a spray feeder, and particles of the sterilizing water float to a minute size and reach every corner of the refrigerating chamber.

At this time, the sterilizing water may be continuously supplied to the refrigerating chamber, but excessive supply of sterilizing water may cause the inside of the refrigerating chamber to be moistened, so that a constant amount of sterilizing water is sprayed at an appropriate time interval (for example, 1 to 5 minutes). And a controller for intermittently supplying the sterilizing water through the feeder.

Above all, the electrode unit according to the present invention is formed as a projection electrode with a plurality of protrusions protruding from the electrode plate facing each other, by applying a low current of 30mA to 220mA to the electrode portion to maintain the amount of hypochlorous acid produced at a low concentration, High sterilization power can be achieved with low power consumption.

On the other hand, according to another field of the invention, the present invention, in the refrigerator to supply cold air to the refrigerating chamber through the cold passage, the sterilized water containing residual chlorine containing hypochlorite by electrolysis of water containing chlorine Generating a; Spraying the sterilizing water onto the cold air passage and supplying the sterilizing water to the refrigerating chamber together with cold air in a state where the sterilizing water is sprayed; It provides a sterilization deodorizing method of the refrigerating compartment, comprising.

The sterilizing water is intermittently injected into the cold passage.

On the other hand, the chlorine-containing water may be used as any one or more of the water that can be used as drinking water, such as tap water, ground water, purified water, etc., in order to increase the amount of hypochlorous acid with high sterilizing power, it is about pH 4.5 to pH 7.5 to It has a neutral nature. Through this, chlorine is contained in a large amount, while preventing disgusting odors while maximizing the amount of hypochlorous acid having high sterilizing power and odorless and deodorizing performance in residual chlorine, high sterilizing power and deodorizing effect can be obtained even at room temperature. . (Thus, the residual chlorine are those that the components, including a OCl such as hypochlorous acid, hypochlorite ion, chlorine ion (Cl - not including a).)

In particular, tap water or groundwater, which can be easily obtained anywhere, corresponds to a weak acidity to neutral constant since the pH value is in the range of about 6.0 to 7.0. Therefore, without any extra effort, by connecting a water pipe to the refrigerator and supplying a constant amount of tap water to the container by a valve, a separate cost or device for the weakly acidic to neutral water required to prepare the sterilized water It can be supplied simply without.

The current supplied to the electrode portion is supplied by a DC voltage of about 3.0V to 4.5V. And the time to energize the said electrode part is set to about 10 second-300 second. This makes it possible to produce the amount of sterilizing water necessary to sterilize and deodorize the entire refrigerator through a maximum operating time of about 5 minutes without going through a long time process for producing sterilized sterilized water.

Sterilized water containing residual chlorine including hypochlorous acid is provided with oxidants such as ozone (O 3 ), hydrogen peroxide (H 2 O 2 ), OH radicals, hypochlorous acid (HOCl), and residual chlorine by electrolysis. The production, sterilization, and deodorization process is carried out by the following steps (1) to (5).

(1) Ozone is generated by electrolysis of water (H 2 O) and finally ozone is formed through the following process where O and O 2 are combined.

H 2 O -> H + + (OH) ads + e -

(OH) ads -> (O ) ads + H + + e -

2 (OH) ads -> O 2 + 2H + + 2e -

2 (O) ads- > O 2

(O) ads + O 2- > O 3

(2) Hydrogen peroxide is produced by the direct route by the electrolysis of oxygen and the indirect route produced by the combination of OH radicals, an intermediate product produced by ozone decomposition. In other words,

O 2 + E - -> O 2 · -

O 2 + 2H + + 2e - -> H 2 O 2

With a direct path such as

OH + OH-> H 2 O 2

Is generated by an indirect path such as

(3) HOCl reacts with H 2 O to form HOCl after Cl − ions in water bind with Cl 2 . In other words,

2Cl - -> Cl 2 + 2e -

2H 2 O + 2e - -> H 2 + 2OH -

Cl 2 + H 2 O -> HOCl + H + + Cl -

(4) OH radical is directly measured is not possible, however, OH if ozone is present in the water due to disappear was instantly generated - or conjugate base of HO 2 of the hydrogen peroxide-forming a and radical chain cycle reaction, and finally Produces OH radicals.

O 3 + OH-> Radial Chain Reaction-> OH

O 3 + HO 2 - (H 2 conjugate base of O 2) -> radical chain reaction -> OH ·

(5) Microorganisms (microorganisms) present in water are inactivated or removed by the oxidants produced, and the following microorganisms are removed by electrosorption, and the following microorganics are e- and It is removed by direct electrolysis reaction.

In other words, for Microorgainsm

M (Microorganism)-> Electrosorption-> Inactivation

Also,

M (Microorganism) + O 3- > Inactivation

M + OH ·-> Inactivation

M + HOCl-> Inactivation.

And about Microorganics,

M (Microorganics) + e--> M-

Also,

M (Microorganics) + O 3- > Product

M + OH

M + HOCl-> Product

That is, during the electrolysis, deodorization and sterilization are smoothly performed by the mixed oxidants (O 3, H 2 O 2, HOCl, OH radicals) generated in the process of (1) to (5), and electrolysis is performed. Afterwards, high sterilizing power is maintained by high residual hypochlorous acid (HOCl). In addition, since the hypochlorous acid (HOCl) produced in step (3) is generated in weakly acidic to neutral saline, chlorine ion (Cl − ) or hypochlorite ion (Cl − ), which has a relatively low bactericidal power and may cause side effects in the human body (HCl). It is possible to reduce the component ratio of OCl − ) and to significantly increase the component ratio of hypochlorous acid (HOCl) having high deodorizing and sterilizing power.

On the other hand, the power supply unit can be configured to apply the application direction of the power applied to the electrode plate upside down. That is, by periodically changing (+) (-) of the power supplied to the negative electrode portion and the positive electrode portion, the initial negative electrode portion does not act only as the negative electrode portion, and at the same time, the initial positive electrode portion does not act as the positive electrode portion only, As one electrode part alternately plays a role of the negative electrode part and the positive electrode part, the oxidation and reduction reactions alternately occur, thereby preventing the solid solution from being attached to each electrode plate during the electrolysis process. This may be alternately changing the direction of the current applied to the electrode plate during operation, may be set to a number of times from 1 to 10 times, may be set in advance, such as 2 to 5 days.

In addition, the plate-shaped negative electrode portion and the plate-shaped positive electrode portion are formed with a negative electrode projection and a sharp projection having a pointed end so as to face each other. This is because even though a constant charge flows, a lot of charges are concentrated at the tips of the sharp protrusions of the negative electrode part and the positive electrode part, thereby facilitating more electrolysis. Therefore, when the same electrolysis is to be induced, it is possible to provide a power supply of a lower capacity, and in particular, it is possible to generate sterilized water containing residual chlorine for a long time even with low power consumption. Here, the tip portions of the cathode projection and the anode projection are not necessarily pointed, and may be columnar. This allows more intense electrolysis at the end of the protrusion even when the same current is applied to the electrode, so that a large amount of oxidant that sterilizes bacteria, bacteria, viruses, etc. in a short time is generated.

In this case, the cathode protrusion and the anode protrusion may be formed of or plated with platinum (Pt), titanium (Ti), graphite, or the like, which can most actively react with electrolysis. In addition, the thickness of the plating layer of the cathode projection and the anode projection is more thick than the plating layer thickness of the other portion is effective in terms of increasing the reaction life. In particular, in the case of being used as a portable, it is desirable to form a large size of the electrode plate while generating a large amount of oxidant, and thus, it is preferable to form or coat with platinum that can most actively react with electrolysis.

Here, the gap d1 between the positive and negative protrusions may be 0.5 mm to 2.0 mm. This is because, when the gap d1 between the positive and negative electrode projections is smaller than 0.5 mm, a sufficient amount of sterilizing water does not flow between the negative electrode plate and the positive electrode plate, so that a large amount of oxidant including residual chlorine is not produced. When the gap d1 between the positive and negative electrode projections is larger than 2.0 mm, the distance between the negative electrode plate and the positive electrode plate is too far apart and the movement of electrons is not sufficient. In addition, when the distance between the electrode plate is too wide, there is a problem that the battery consumption is larger.

However, if a small amount of oxidant is to be produced, the space between the protrusions may be narrower, so that the gap is about 0.5 mm, and in case of generating a large amount of oxidant, sufficient contact space is secured. It is effective to be spaced apart from about 1.0mm to 1.5mm in order to.

On the other hand, the negative electrode plate formed in a plate shape and the branch plate branched from the plate surface of the positive electrode plate protruding, the branch plate branched from the negative electrode plate and the branch plate branched from the positive electrode plate are arranged to face each other one by one, Opposite branch plates are formed with cathode and anode protrusions, respectively. Through this, it is possible to secure more areas where electrolysis occurs in a minimum space. Furthermore, another branch plate may be formed from the branch plate, and the cathode and anode protrusions may be formed on opposite surfaces of the other branch plates extending from the positive electrode unit and the negative electrode plate, respectively.

As described above, the present invention includes a main body for selectively forming a sealed space with the outside by opening and closing the door; An evaporator for cooling the surrounding air; A cold air passage communicating the evaporator and the sealed space; A blower for forcibly transferring the cold air around the evaporator to the sealed space; A container containing water containing chlorine; An electrode part installed so that the positive electrode part and the negative electrode part face each other while being immersed in water of the container; A power supply unit supplying power to the electrode unit; A feeder for supplying sterilizing water containing residual chlorine containing hypochlorous acid generated by electrolysis of the electrode portion to the refrigerating compartment; It is configured to include, the sterilization water is supplied to the air in the refrigerating chamber to effectively remove the smell of food or ingredients stored in the refrigerating chamber to provide a refrigerator and refrigerating room sterilization deodorizing method for realizing a comfortable refrigerating chamber environment.

In addition, the present invention is prepared by dissolving chlorine-containing water electrolytically to produce sterilized water containing a high sterilizing power and harmless human hypochlorite, but a low content of residual chlorine, such as chlorine ions, in the refrigerating compartment in the form of fine particles By being supplied to every corner of the refrigerating chamber in a state suspended in the supplied cold air, a hygienic refrigerating environment is provided by effectively sterilizing bacteria and mold in the refrigerating chamber.

That is, the refrigerator compartment of the refrigerator according to the present invention is killed by bacteria or mold by the sterilizing water supplied with the cold in the form of particles, so that food or ingredients stored in the refrigerator compartment can be refrigerated for a longer time without being damaged. Advantageous effects are obtained.
