Description

[Detailed description of the invention] [Industrial application field] This invention removes or prevents bad odors that occur in closed spaces such as home refrigerators, commercial refrigerators, refrigerated storage cases, shoe racks, lockers, etc. The present invention also relates to a compact deodorizing device used to prevent the generation of mold and the like.

[Prior Art] For example, refrigerators and shoe racks are opened and closed as needed on a daily basis, but food stored in the refrigerator always emits various odors peculiar to the food. Shoes, sandals, etc. stored in the shoe cabinet emit odors such as sweat soaked in these shoes and sandals, and these odors are released into the atmosphere as the door is opened and closed. Some of these odors are pleasant, but most of them are unpleasant odors, and when a variety of foods are stored, such as in a refrigerator, the odor of a certain food may become unpleasant. It may also adhere to other foods and impair their flavor.

For this reason, in the past, deodorizing agents such as activated carbon or aromatics that generate a pleasant odor were generally installed in this closed space, and the odors generated within this closed space were removed by chemically or physically adsorbing them. Or,
Alternatively, bad odors are alleviated with aromas. However, with this deodorizing method using a deodorizing agent, there are restrictions on the amount of odors that can be removed depending on the type of deodorizing agent, and there are also restrictions on the amount that can be removed, and furthermore, the deodorizing efficiency decreases over time. In addition, the method of using air fresheners requires the use of a wide variety of fragrances since different users have different scent preferences. There is a problem that the characteristic fragrance of the products is lost.

Therefore, unlike methods using such deodorizers and fragrances, a deodorizing device has been proposed that is equipped with an ozone generator and causes the ozone generated from the ozone generator to react with the malodorous components to decompose the malodorous components. (Utility Model Application Publication No. 61-24054).

[Problems to be solved by the invention] However, in the conventional deodorizing device described above, a reaction tank is formed in the device in order to effectively react the ozone generated in the ozone generator with malodorous components, and this reaction tank is An electric blower is used inside the building to suck in malodorous components and cause them to react with ozone, so a household or commercial power source or vehicle battery is required to power the ozone generator or drive the electric blower. Therefore, there was a problem in that they could only be used in places that had power sources, and could not be used in places without power sources, such as home refrigerators, shoe racks, lockers, etc.

Therefore, the purpose of the present invention is to be able to be easily installed in places where there is no dedicated power supply for home or business use, or a vehicle battery, etc., and to eliminate bad odors generated in such closed spaces. It is an object of the present invention to provide a compact deodorizing device capable of preventing the generation of mold and mildew.

[Means for Solving the Problems] That is, the present invention includes a casing having an intake port at the top and an exhaust port at the bottom, and at least one tip disposed between the intake port and the exhaust port. A corona discharge part having a discharge electrode having a pointed discharge needle and a counter electrode, a battery set in a battery storage part formed in the casing, and generating high voltage based on the power supplied from the battery. This is a small deodorizing device that consists of a high voltage generator and discharges ozone generated in the corona discharge section from the exhaust port of the casing based on the difference in specific gravity with air.

In the present invention, the intake port formed in the casing is formed in the upper part of the casing, and preferably in the upper surface for those used in places where water droplets do not occur, such as in shoe racks and lockers. In addition, for appliances used in places where there is a possibility of water droplets, such as household refrigerators, it is preferable to form a seal on the upper side to prevent water from flowing in. For appliances such as refrigerators that have a built-in fan and are used in places where a specified air flow is generated, the ozone generated in the corona discharge section can be efficiently discharged from the exhaust port by following the flow. It is best to install it so that the intake and exhaust ports are aligned.

The corona discharge section disposed within the casing has a discharge electrode having at least one pointed discharge needle in order to smoothly discharge at a relatively low voltage and efficiently generate ozone. The counter electrode is preferably formed into an appropriate shape such as a circle, a rectangle, a regular hexagon, etc., with the tip of the pointed discharge needle of the discharge electrode located at the center thereof. It is preferable to use a type that has through holes or is made of a conductive net.

The battery and high-voltage generator that supply power to this corona discharge section are connected to the inlet port → the corona discharge port in order to discharge the ozone generated in the corona discharge section from the exhaust port of the casing based on the difference in specific gravity between the corona discharge section and the air. It is formed in a position that does not impair the flow of ozone and/or air from the exhaust port to the exhaust port. As for batteries used as a power source, primary batteries that cannot be recharged but are easy to handle and secondary batteries that can be recharged can be used, as well as solar cells and fuel cells that can be used by using thin lead wires. For the battery compartment that can be used and where these batteries can be set, for example, connect two or three 1.5V single batteries in series,
It is best to form a space in which a predetermined number of these batteries can be arranged side by side (usually 2 to 4 rows), and as a high-voltage generator, the voltage of the batteries stored in the battery storage part is discharged in a corona discharge part. high enough voltage to generate ozone, usually 1~
It can be boosted to 5kV, preferably 2 to 4kV, and specifically, for example, DC-DC
Examples include converter type high voltage generators.

[Function] The compact deodorizing device of the present invention is installed above a closed space such as a home refrigerator, commercial refrigerator, refrigerated showcase, shoe rack, locker, etc., and the ozone generated by the ozone generator inside the casing is removed from the air intake port. It is directly supplied into this closed space along with the air taken into the casing from the air, and removes or prevents the occurrence of bad odors generated within this closed space, and also prevents the generation of mold, etc. within this closed space. Furthermore, when ozone moves into the closed space from the exhaust port, the air in the closed space is sucked into the casing from the intake port, and at this time, the odor components sucked into the closed space along with the air are combined with ozone. During or after the reaction, it is discharged into a closed space, and in this way the difference in specific gravity between ozone and air [ozone density (0°C, 1 atm):
2144g/, air density (0℃, 1atm): 1293g/
] is used to create a flow of ozone generated by an ozone generator, and also to diffuse ozone into a closed space.

[Example] In FIGS. 1 to 4, a small deodorizing device according to an example of this invention is shown. The inside of this small deodorizing device is partitioned into left and right by a vertical partition wall 1a, and the right side in the drawing is a horizontal partition wall 1a.
Three spaces 1c and 1d are divided into upper and lower parts by
and 1e, an intake port 2 communicating with the space 1c is formed on the upper side surface of the space 1c, and an exhaust port 3 communicating with the outside from the space 1c is formed on the bottom bottom surface of the space 1c.

a plurality of batteries 9 set in a space 1d located on the right side in the drawing and partitioned by a horizontal partition wall 1b and located below, that is, in a battery storage section 10; This battery compartment 1
A high voltage generator 11 is installed in a space 1e formed above 0.

In this embodiment, a display panel 14 having a switch 12 and an indicator lamp 13 is attached to the front surface of the casing 1 forming a space 1e, and a battery storage section 10 is provided with a display panel 14 for storing batteries therein. A contact point 15 made of an elastic spring material and serving as a battery holder is provided, and the high voltage generator 11 is composed of a high voltage pack 11a and a control board 11b. This high pressure pack 11
A is a device that converts the DC3 to 6V of the battery 9 into AC, boosts it, rectifies it again, and extracts high-voltage DC.The current-voltage ratio is to prevent overcurrent from flowing when the high-voltage circuit is short-circuited. It is protected by an overcurrent prevention circuit whose characteristics are fold-back. The control board 11b also includes a detection section that detects the voltage drop from the battery 9 and displays it using a lamp (not shown), a timer set from the outer surface of the casing 1, a voltage adjustment section, and the like.

Therefore, according to the small deodorizing device of this embodiment,
The voltage of the battery 9 is boosted to a predetermined level by the high voltage generator 11, and the obtained high voltage is supplied to the corona discharge section 4 in the space 1c, and the discharge needle 7 of the discharge electrode 5 and the pointed discharge needle 7 of the discharge electrode 5 are connected to each other. A corona discharge is caused between the casing 1 and the counter electrode 6, and the ozone generated at that time is discharged from the exhaust port 3 of the casing 1 to the outside (corresponding to a closed space such as a household refrigerator). At this time, external air is sucked into the space 1c from the intake port 2 of the casing 1, but this air passes through the circular hole 8 of the counter electrode 6 and is discharged from the exhaust port 3 together with the generated ozone. In this way, extremely slow air convection usually occurs within the closed space where this small deodorizing device is installed.
Ozone discharged outside deodorizes and sterilizes the closed space.

Next, FIGS. 5 to 8 show the corona discharge section 4.
The corona discharge section 4 in FIG. has a counter electrode 6 having three regular hexagonal through holes 8 located at its center,
In the corona discharge section 4 shown in FIG. 6, the counter electrode 6 located below the pointed discharge needle 7 of the discharge electrode 5 is formed of a conductive net, and the corona discharge section 4 shown in FIG.
A counter electrode 6 made of a conductive net is formed in a spherical shape, and the discharge electrode 5 shown in No. 8 has a pointed discharge needle 7 attached to the discharge electrode body by welding.

[Effects of the invention] The small deodorizing device of the invention can be used in household refrigerators, commercial refrigerators, refrigerated storage cases, shoe racks,
It can be easily installed in a closed space where there is no dedicated power supply or vehicle battery such as a rotary car.
The ozone generated in the corona discharge section can remove or prevent the occurrence of bad odors in the closed space, and can also prevent the occurrence of mold and the like. For this reason, if it is installed inside a household refrigerator, for example, it can maintain the freshness of food and prevent the transfer of odors between different foods.Also, if it is installed inside a shoe rack, for example, it can eliminate the smell of footwear and It can prevent mold from forming.

In addition, the corona discharge unit used in this invention can easily control discharge by adjusting the supplied voltage, so the amount of battery used can be adjusted depending on the size of the closed space and the contents. By adjusting the amount of ozone generated, deodorizing and sterilizing effects can be achieved under optimal conditions.
