The present invention relates to a sterilizer of a refrigerator, and more particularly, by spraying an air bubble (bubble) containing an antimicrobial agent into the refrigerating compartment, the instant the antimicrobial agent is blown against the inner wall of the refrigerating compartment or a container placed in the refrigerating compartment. The present invention relates to a sterilizer of a refrigerator which is sterilized while being spread.

In general, as shown in FIG. 1, the refrigerator is supplied with cold air cooled in the evaporator 3 into the freezer compartment 1 and the refrigerating compartment 2, and the supplied cold air is provided along the circulation passage 4. Cooled again while circulating.

At this time, since the refrigerated food (2) is stored in a closed state refrigerated food is used for a long time, harmful bacteria inhabit the refrigerated food is unsanitary.

Therefore, a sterilizer for sterilizing these bacteria is provided in the refrigerating chamber 2.

That is, a bioceramic filter 5 is installed on the circulation passage 4 above the refrigerating chamber 2.

The filter 5 serves as a porous low temperature catalyst having a large number of holes through which cold air passes, and after cooling the inside of the refrigerating chamber 2, the cold air directed toward the evaporator 3 along the circulation passage 4 is filtered. Sterilized in the process of passing (5).

However, when the filter 5 freezes in a state where dew is generated on the surface, the hole is clogged, which causes trouble in the cold air flow, and the use of the filter 5 may cause a hassle that needs to be replaced regularly since the sterilization performance is reduced.

On the other hand, a device for sterilization using ozone has been disclosed in the domestic Utility Model Publication No. 91-2895.

This is sterilized by ozone generated in the ozone generator installed in the refrigerating chamber. The cold air is sterilized in the course of passing through the ozone generator and then supplied to the refrigerating chamber through an ozone decomposition catalyst for removing ozone contained in the cold air.

However, since an ozone generator, a fan and a motor for circulating cold air, and a catalyst for decomposing ozone are required, an unreasonable problem has arisen such as a complicated structure of the device and an increase in manufacturing cost.

The present invention was developed to solve the above problems, an object of the present invention, by dropping the antimicrobial solution dissolved in the antibacterial solution to the ring buried by the force of cold air discharged to the ring through the guide tube is formed When the air bubbles collide with the inside wall of the refrigerating chamber or the container containing the refrigerated food, the air bubbles are spread around and sterilized in the process of floating, thus simplifying the composition of the sterilizer. Is in.

In order to achieve the above object, the present invention sterilizes the inside of the refrigerating chamber connected through the freezer compartment and the cold air duct, wherein the sterilizing solution in which the sterilant is dissolved is dropped into a ring, and the sterilizing film is formed. Air bubbles are formed is characterized in that the sterilization means is provided to float the inside of the refrigerator compartment.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

2 is a cross-sectional view of the refrigerator to which the present invention is applied, and the freezing chamber 10 and the refrigerating chamber 11 are separated from the partition 12 and the evaporator 13 is installed behind the refrigerating chamber 10.

The evaporator 13 cools the air in the freezer compartment 10 and the refrigerating compartment 11, and the cold air of the refrigerating compartment 11 and the freezer compartment 10 is circulated by the fan 14 installed above the evaporator 13.

That is, the cold air cooled by passing through the evaporator 13 is sucked into the fan 14, and most of it is discharged into the freezer compartment 10 in front, and part of the inside of the refrigerating chamber 11 along the cold air duct 15 formed rearward. Is discharged.

On the other hand, the discharged cold air is frozen and refrigerated in the freezer compartment 10 and the refrigerating compartment 11, and then returned to the evaporator 13 along the circulation passage 16 installed in the partition 12.

On the other hand, the sterilization means 20 is installed in the upper rear of the refrigerating chamber 11 is inflated by the force of the cold air discharged into the refrigerating chamber 11, the air bubbles 29 are formed.

The sterilizing means 20 is that the air bubbles 29 are naturally formed by the wind pressure of the cold air discharged to the ring in a state in which the sterilizing agent in which the sterilizing agent is dissolved falls on the ring to form a film, and the air bubbles 29 formed in the refrigerating chamber ( 11) It will float inside.

The air bubbles 29 floating in this way are disinfected while spreading and colliding with the inner wall of the refrigerating chamber 11 or a container in storage.

3 is a perspective view of the sterilization apparatus of the present invention, Figure 4 is a cross-sectional view of the sterilization apparatus of the present invention.

A cold air duct 15 through which cold air heat-exchanged from the evaporator is supplied to the refrigerating chamber is formed at the rear of the refrigerating chamber, and an outlet 15a is formed at the lower end of the cold air duct 15 to communicate with the refrigerating chamber 11.

Sterilization means 20 is installed in front of the discharge port (15a), the sterilization means 20 is installed in front of the discharge port (15a) and the body 21 forming the outer case of the sterilization means (20) is The guide tube 22 is formed by opening the rear lower side and extending inward so that the cold air discharged from the discharge port 15a is introduced.

A ring 27 formed by winding a circular coil is connected to the tip of the guide tube 22 by a wire 28, and a sterilization container in which a sterilizing solution is stored inside the ring 27 is vertically above the ring 27. 24) is installed.

At the lower end of the sterilization vessel 24, an outlet 25 is formed so that the sterilization liquid stored therein falls into the ring 27.

The outlet 25 is provided with a control valve 26 for controlling the sterilization liquid to drop intermittently by a predetermined amount.

The control valve 26 is a solenoid type electronic control valve. When an electrical signal is input, the outlet 25 is intermittently opened and the sterilizing liquid is buried in the ring 27.

That is, the amount enough to form a film by burying the sterilizing solution drops intermittently.

In the present invention configured as described above, the cold air circulating in the refrigerating and refrigerating chambers 10 and 11 by the rotation of the fan 14 is introduced into the evaporator 13 along the circulation passage 16 and then cooled by heat exchange.

In addition, the cooled cold air is discharged into the freezing chamber 10 in front of the fan 14 and the cold air duct 15 in the rear.

The cold air supplied to the cold air duct 15 is circulated into the refrigerating chamber 11 through the discharge port 15a.

On the other hand, when the refrigerator is used for a long time, the harmful bacteria are invisible in the refrigerating chamber 11 due to the refrigerated food.

At this time, the control valve 26 is operated regularly.

That is, when the control valve 26 is intermittently opened, the sterilizing film is formed while the sterilizing liquid is dropped into the ring 27 through the outlet 25.

At this time, since a part of the cold air discharged to the discharge port 15a through the cold air duct 15 flows into the guide tube 22 and then is discharged to the ring 27, the film formed on the ring 27 naturally has air bubbles 29 And spreads into the refrigerating chamber 11 through the outlet 23.

At this time, as the sterilization film is deformed into the air bubbles 29, the control valve 26 is opened again and the sterilization liquid is dropped back to the ring 27 to form a sterilization film and another air bubble 29 is formed.

When this process is repeated several times, several air bubbles 29 are sprayed into the refrigerating chamber 11 through the outlet 23 and float.

In this way, when the air bubbles 29 float, they collide with each other when they collide with the interior wall of the refrigerating chamber or the container containing the refrigerated food.

At this time, the surroundings are naturally sterilized.

On the other hand, since sterilization proceeds while the air bubbles 29 directly collide with the inner wall of the container or the refrigerating chamber, the sterilization effect is improved.

As described above, according to the present invention, the disinfectant disinfectant disinfects into the ring, and the cold air is discharged while the sterilization film is formed by the surface tension of the disinfectant solution. The air bubbles are formed and the air bubbles flow in the refrigerating chamber. Since it is sterilized by floating and colliding with the surroundings, the sterilization effect is improved and the composition of the sterilizer is simplified.
