Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a locker for accommodating clothes and the like used in hospitals, etc., and in particular, it can sterilize every corner while accommodating clothes, etc. The present invention relates to a sterilization locker that can be used safely in a short time.

[0002]

2. Description of the Related Art In hospitals, clinics, and medical laboratories, pathogenic bacteria in the atmosphere of hospital rooms, ICUs, walls, floors, etc.
Especially in the presence of MRSA (methicillin-resistant Staphylococcus aureus), there is a risk of infecting patients, visitors and medical staff, and therefore sterilization and disinfection in the room are encouraged. In addition, clothes such as white coats and hats are frequently changed, and these clothes are similarly sterilized and disinfected.

Examples of the sterilization and disinfection (hereinafter referred to as "sterilization") methods include heating and ultraviolet rays. The method by heating has an advantage that, for example, boiling clothes can be surely sterilized in every corner and there is no harmful residue. The method using ultraviolet rays has an advantage that it can be sterilized with high sterilizing power by irradiating the clothes with an ultraviolet ray tube or the like which is generally known as a sterilizing lamp, and there is no harmful residue.

[0004]

The above-mentioned sterilization method is
There are the following problems.

(1) In the method using heating, it takes time to raise the temperature of boiling water, and cooling is required after heating. Therefore, it takes time to complete the sterilization.

(2) In the method using ultraviolet rays, since ultraviolet rays have a straight-forward property, many rugged articles such as clothes, pockets, backsides, and overlapping portions are not sterilized.

As described above, the conventional disinfection methods have problems that the sterilizing effect does not reach every corner, harmful residues remain, and waiting time for disinfection occurs. Therefore, disinfection in hospitals is effective and safe. Moreover, it could not be performed in a short time.

(3) Further, clothes are usually stored in a locker, and used clothes must be taken out from the locker, sterilized, and then stored again in the locker, and the inside of the locker must be sterilized. Because it is troublesome.

On the other hand, it is considered that the ozone source is placed in the locker to fill the locker with ozone. If fumigated with ozone, not only is the bactericidal power high, but since it is a gas, it diffuses and spreads evenly in the locker and permeates clothes. Further, although ozone is harmful to the human body, it is relatively easy to collect and decompose. For example, ozone can be decomposed simply by passing it through an ozone killer,
Further, ozone has a property of spontaneously decomposing when left to stand. Therefore, residual ozone can be easily prevented. However, also in this case, in order to shorten the sterilization time, a ventilation fan is installed to actively diffuse the ozone from the ozone generation source and to help the ozone killer to decompose the atmosphere in the locker. There is a need to.

By the way, ozone has a property of corroding metals, and if a blower fan or an ozone generating source is placed in a locker, they themselves are exposed to ozone. Also, in order to perform efficient sterilization in order to reduce the time, it is necessary to operate the ozone source and the blower fan with good timing, but automatic operation is necessary because the locker must be operated at all times. Therefore, the control device for performing this automatic operation is also exposed to ozone. In order to use ozone, the ozone resistance of the device itself must be improved.

Therefore, an object of the present invention is to solve the above problems and provide a sterilization locker which can be sterilized in every corner, has no harmful residue after completion, has a short waiting time, and can be used safely. It is in.

[0012]

To achieve the above object, the present invention relates to a sterilization locker for sterilizing a sterilization target housed in a locker with ozone, and a locker chamber for storing the sterilization target in the locker and ozone. It is formed by partitioning it with the machine room that houses the ozone generation unit that is generated, and connects the ozone generation unit with an ozone blowing pipe that guides the ozone generated in the unit and blows it out from the upper part of the locker room, and exhausts it into the machine room. A fan is provided and an exhaust louver is provided in the machine room, while an external ozone killer for introducing external air is provided in the locker room, and the air in the locker room is introduced into the machine room between the locker room and the machine room. It is equipped with an internal ozone killer that decomposes ozone as well as exhausts it.

Further, according to the present invention, in a sterilization locker for sterilizing a sterilization target housed in a locker with ozone, a locker chamber for storing the sterilization target in the locker and a machine room for storing an ozone generating unit for generating ozone are provided. It is divided into parts and connected to the ozone generation unit, an ozone blow-out pipe that guides ozone generated in the unit and blows out from the upper part of the rocker chamber, sucks the air in the rocker chamber into the machine chamber and returns it to the rocker chamber. A circulation duct and a circulation fan are provided, and an ozone killer is provided at the intake and exhaust ports of the circulation duct.

In the sterilization locker of the present invention, the locker chamber is divided into a plurality of locker chambers, and each of the locker chambers is provided with an ozone blowing pipe, and each of the blowing pipes is provided with a valve. Each locker room may be configured to be a locker room during sterilization, ozone decomposition, and use.

In the sterilization locker of the present invention, the machine room is integrally provided with the ozone generating unit, the ozone blowing pipe, the circulation fan, and the ozone killer provided on the intake / exhaust port side of the circulation fan. The unitized machine room may be housed in the locker.

Further, the present invention provides a sterilization locker for sterilizing a sterilization target housed in the locker with ozone, comprising a locker chamber for storing the sterilization target in the locker and a machine room for storing an ozone generating unit for generating ozone. It is divided into upper and lower parts, and a blower path extending from the machine room along the side of the locker room is formed in the locker. An ozone blow-out pipe that blows from the upper part is connected, an external ozone killer for introducing external air is installed in the locker room, and an internal ozone killer that connects both the locker room and the machine room is provided in the locker room. A blowout ozone killer is installed on the discharge side of the ventilation passage to suck the air in the locker room into the machine room through the internal ozone killer. Provided with an exhaust pump, its blow side of the exhaust pump, which are connected freely switch between circulation path in which the once-through exhaust path for exhausting the sucked air to the outside of the rocker back into air passage.

The sterilization locker of the present invention is provided with an opening / closing lever on the openable / closable door of the locker chamber, a lock for locking the door, and an electromagnetic lock for locking / unlocking the lock. An unlock button is provided to give an unlock signal to the lock, and the door can be opened and closed when the unlock button is on while the electromagnetic lock is energized, but the unlock button is turned on when the locker chamber is sterilized or ozone decomposed. However, you may provide the control apparatus which controls an electromagnetic lock so that it may be locked.

[0018]

According to the above construction, when ozone is generated in the ozone generating unit and the generated ozone is blown out into the rocker chamber from the ozone blowing pipe, the ozone is filled in the locker chamber and the sterilization target is secured in every corner. To be sterilized.

In the case of the one-through decomposition method, by operating the exhaust fan at a low speed during ozone generation, the locker chamber is made to have a negative pressure, and it is possible to prevent ozone from leaking from the locker chamber to the outside of the locker.

When the sterilization is completed, the ozone generating unit stops the generation of ozone, and in the case of the one-through decomposition method, the exhaust fan is operated and the air outside the rocker is introduced into the rocker chamber through the external ozone killer, The ozone in the room is decomposed by the internal ozone killer and is forcibly discharged into the machine room together with the air introduced from the outside of the locker. The air in the machine room is forcedly exhausted to the outside of the rocker via the louver. That is, since a flow can be made in a fixed direction (direction from top to bottom) in the locker chamber, ozone is decomposed in a short time. When the exhaust fan is operated for a predetermined time, ozone in the locker chamber is completely decomposed and no ozone remains, so that the sterilized clothes can be safely taken out from the locker chamber.

On the other hand, in the case of the circulation type ozone decomposition method, when the ozone generation unit stops the generation of ozone,
The circulation fan operates to introduce the ozone in the locker chamber into the circulation duct, decomposes it into oxygen by the ozone killer in the circulation duct, and returns the oxygen into the locker chamber. Ozone in the locker chamber is introduced together with oxygen into the circulation duct, decomposed into oxygen and returned to the locker chamber. In this way, the air in the locker chamber repeatedly passes through the ozone killer in the circulation duct, so that the ozone in the locker chamber is completely decomposed.

Further, by switching the exhaust path of the exhaust pump, the one-through decomposition method and the circulation decomposition method can be switched.

When the locker chamber is divided into a plurality of locker chambers, each locker chamber can be independently made into a sterilizing chamber, an ozone decomposing chamber, and a usable locker chamber by opening and closing a valve.

By unitizing the machine room, the manufacturing process of the sterilization locker can be shortened.

While the electromagnetic lock is energized, the door can be opened and closed when the unlock button is on, but it can be locked even if the unlock button is turned on during sterilization or ozone decomposition of the locker room. Accidental opening of the door is prevented if ozone remains.

[0026]

An embodiment of the present invention will be described in detail below with reference to the accompanying drawings.

FIG. 1 is a conceptual diagram of an embodiment (one-through ozonolysis method) of the sterilization locker of the present invention.

In FIG. 1, reference numeral 1 is a sterilization locker for sterilizing clothes 2 to be sterilized contained in the locker with ozone, and a locker room 3 for housing the clothes 2 and a machine room 4 are defined in the locker. The upper part is the rocker room 3 and the lower part is the machine room 4.

An ozone generating unit 5 for generating ozone is housed in the machine room 4. Ozone generation unit 5
Is composed of a compressor 6 that sucks and compresses the air in the machine room 4, and a device called an ozonizer 7.
The ozonizer 7 has a discharge electrode and is configured to ionize oxygen in the air compressed by the compressor 6 by discharge to generate ozone. The ozonizer 7 is connected to a substantially L-shaped ozone blowing pipe 8 that guides ozone and blows off from the upper part of the locker chamber 3. The ozone blowing pipe 8 is
It is made of a material that is not corroded by ozone, such as stainless steel. A plurality of holes 8b are formed in the upper outlet part 8a of the ozone blowing pipe 8 in order to uniformly blow the ozone to the clothes 2 (the number of the holes 8b is four in the figure, but is not limited). The ozone outlet upper part 8a may be formed in a plate shape having a plurality of holes. Incidentally, Fc is a cooling fan for cooling the ozone generating unit 5.

Between the locker chamber 3 and the machine chamber 4, the air inside the locker chamber 3 is exhausted into the machine chamber 4, and an internal ozone killer for decomposing ozone from the locker chamber 3 into oxygen. 9 is provided. Internal ozone killer 9
An exhaust fan 10 that forcibly exhausts the air in the rocker chamber 3 into the machine chamber 4 to make it a negative pressure is provided on the lower side, and the exhaust efficiency is improved around the exhaust fan 10. A cylindrical fan cover 11 is provided for this purpose (the motor for rotating the exhaust fan 10 is omitted for clarity). A louver 12 for exhausting the air in the machine room 4 to the outside of the locker is provided in the lower part 4a of the machine room 4. The louver 12 may be provided with a mesh filter to prevent dust, dust, insects, etc. from entering the machine room 4. If the sterilization locker shown in the figure is used as it is, the louver 12 will be closed, but it goes without saying that it is lifted up by a leg or the like not shown in the figure.

An external ozone killer 13 for introducing air outside the locker into the locker chamber 3 is provided on the upper portion 3a of the locker chamber 3. The locker chamber 3 is also made of a material that is not corroded by ozone, such as stainless steel, like the ozone blowing pipe 8. External ozone killer 13
In order to prevent the ozone supplied from the ozone generating unit 5 into the locker chamber 3 from leaking to the outside of the locker as it is, it decomposes the ozone that is about to flow to the outside.
The sterilization capacity (or ozone concentration) in the locker room 3 is
It is set by the ozone generation capacity of the ozone generation unit 5, the decomposition capacity of both ozone killer 9, 13, the volume in the rocker chamber 3, and the exhaust capacity of the exhaust fan 10.

Next, the operation of the embodiment will be described.

When the ozone generating unit 5 operates, the air in the machine room 4 is sucked and compressed by the compressor 6,
The compressed air is ionized by the ozonizer 7 to become ozone, which is blown onto the clothes 2 in the direction of arrow A from the upper part in the rocker chamber 3 through the ozone blowing pipe 8. Locker room 3
While ozone increases inside, the air in the locker chamber 3 is exhausted to the outside of the locker chamber 3 mainly through the internal ozone killer 9 (a part of which is the external ozone killer 13) and decreases.
After a certain period of time, the locker chamber 3 is filled with ozone. Since the clothes 2 are sufficiently exposed to ozone, the inside of the pocket and the inside are surely sterilized in every corner. Locker room 3 at the same time
The inside is also sterilized with ozone. Excess ozone in the locker chamber 3 is stored in the internal ozone killer 9 and the external ozone killer 13.
Is decomposed into harmless oxygen and is exhausted to the outside of the locker chamber 3.

In order to remove the sterilized clothes from the locker chamber, it is necessary to stop the ozone generation in the ozone generating unit 5 and decompose the ozone in the locker chamber 3.
Therefore, the ionization of the ozonizer 7 of the ozone generation unit 5 is stopped and the generation of ozone is stopped. The compressor 6 operates for a while and forcibly exhausts the ozone remaining in the ozone blowing pipe 8 into the rocker chamber 3. The exhaust fan 10 rotates as the compressor 6 stops. Ozone in the locker chamber 3 is decomposed by the internal ozone killer 9 and is forcibly discharged into the machine chamber 4 in the direction of arrow B.
The air in the machine room 4 is forcibly discharged to the outside of the rocker through the louver 12 in the direction of arrow C. Since the locker chamber 3 has a negative pressure, fresh air outside the locker is introduced into the locker chamber 3 in the direction of arrow D via the external ozone killer 13. When the exhaust fan 10 rotates, a flow in a fixed direction (direction from top to bottom) can be generated in the rocker chamber 3, ozone in the rocker chamber 3 is reduced, and the rocker chamber 3 can be quickly discharged.
The ozone inside is completely decomposed and disappears. Therefore, since the locker chamber 3 is filled with fresh air from the outside of the locker, the sterilized clothes 2 can be safely taken out from the locker chamber 3.

Further, since the inside of the machine room 4 is not exposed to ozone, the exhaust fan 10 and the ozone generating unit 5 are not corroded. Therefore, the inner wall of the machine room 4, the compressor 6, the motor for the exhaust fan 10 and the fan cover 11
It is not necessary to take measures against ozone such as using stainless steel.

According to the embodiment shown in FIG. 1 above, during the ozone generation, the exhaust fan is rotated at a low speed to make the inside of the rocker a negative pressure, so that the ozone does not leak to the outside.
The seal structure of the door can be simplified. Furthermore, after the clothes stored in the locker room are sterilized with ozone from the ozone generation unit, the ozone used for sterilization is passed through the internal ozone killer only once and decomposed,
Ozone is decomposed safely in a short time. In the figure, the louver 12 and the external ozone killer 13 are the upper part 3 of the locker chamber 3.
a, provided on the lower portion 4a, but is not limited thereto.

FIG. 2 is a conceptual diagram of another embodiment (circulating ozonolysis method) of the germicidal locker of the present invention. Hereinafter, common reference numerals are used for the same members as those in the embodiment shown in FIG.

The difference from the embodiment shown in FIG. 1 is that the residual ozone in the rocker chamber after the sterilization treatment is repeatedly passed through the ozone killer to decompose it (circulating ozone decomposition method).

As shown in FIG. 2, the sterilization locker 20 is provided with a circulation fan 22 for sucking the air in the locker chamber 3 in the machine room 4, and its intake port 21a and exhaust port 21b.
And ozone killer 23 and 24 respectively. A duct 27 extending to the upper portion of the rocker chamber 3 is connected to the exhaust port 21b to improve circulation efficiency.

In such a sterilization locker 20, when the ozone generating unit 5 operates, the compressor 6 operates and sucks the air in the machine room 4. Air to the machine room 4 is sucked in the direction of the arrow H from the inside 3 of the rocker room through the ozone killer 23. The air compressed by the compressor 6 is ionized by the ozonizer 7 to become ozone, and is blown onto the clothes 2 from the upper part in the rocker chamber 3 in the direction of arrow F through the ozone blowing pipe 8. Ozone increases in the locker chamber 3, and the air in the locker chamber 3 is exhausted in the direction of arrow H to the outside of the locker chamber 3 via the ozone killer 23, 24 and decreases. After a certain period of time, the locker chamber 3 is filled with ozone. The clothes 2 are fully exposed to ozone and sterilized in every corner. At the same time, the interior of the locker room 3 is also sterilized with ozone. Excess ozone in the locker chamber 3 is decomposed by the ozone killer 23, 24 into harmless oxygen, which is exhausted to the outside of the locker chamber 3. During the sterilization process, ozone in the locker chamber 3 is sucked into the circulation duct 21 through the intake / exhaust ports 21a, 2a.
The ozone killer 23, 24 decomposes even if it enters from any of 1b, so that the circulation duct 21 and the circulation fan 22 are prevented from being corroded by ozone.

After the sterilization of the clothes 2 is completed, ozone in the locker chamber 3 is decomposed. Therefore, the ionization of the ozonizer 7 of the ozone generating unit 5 is stopped and the generation of ozone is stopped.
The compressor 6 operates for a while and forcibly exhausts the ozone remaining in the ozone blowing pipe 8 into the rocker chamber 3.
When the compressor 6 is stopped and a motor (not shown) is operated to rotate the circulation fan 22, ozone in the rocker chamber 3 is decomposed into oxygen by the ozone killer 23 and is forced into the machine chamber 4 in the direction of arrow H. Inhaled. Oxygen in the machine room 4 is exhausted from the upper part into the rocker room 3 through the duct 27 in the arrow J direction. Similarly, residual ozone in the locker chamber 3 is decomposed into oxygen by the ozone killer 23 and is forcibly sucked into the machine chamber 4 in the direction of arrow H. That is, the air composed of ozone and oxygen in the locker chamber 3 repeatedly passes through the ozone killer 23, 24.
After a certain period of time, ozone in the locker chamber 3 is completely decomposed, and the sterilized clothes 2 can be safely taken out from the locker chamber 3.

According to the embodiment shown in FIG. 2, the clothes contained in the locker chamber are sterilized by ozone from the ozone generating unit, and then the ozone used for sterilization and the oxygen decomposed from ozone are decomposed. Since the air that passes through is repeatedly passed through the ozone killer, the ozone is safely decomposed and the ozone killer can be downsized.

In this embodiment, since the ozone in the locker chamber 3 repeatedly passes through the ozone killer 23, 24, the number of cells constituting the ozone killer 23, 24 can be reduced, and the decomposition ability is small and small. The ozone killer may be used, and the machine room 4 can be downsized accordingly. Further, the ozone killer 24 is provided at the exhaust port 21b in the figure, but it goes without saying that it may be provided inside the duct 27 or at the outlet.

FIG. 3 (a) is a conceptual diagram of another embodiment of the sterilization locker of the present invention, and FIGS. 3 (b) and 3 (c) are modifications thereof.

The feature of this embodiment is that the one-through ozone decomposition method and the circulation type ozone decomposition method can be switched freely.

In FIG. 3A, the sterilization locker 30
Is a locker room 3 for accommodating clothes 2 and a machine room 4 for accommodating an ozone generating unit 5 for generating ozone.
Are formed by being divided into upper and lower parts, and an air passage 31 extending from the machine room 4 along the side part of the rocker room 3 is formed in the locker. The ozone generating unit 5 is connected to an ozone blowing pipe 8 which guides ozone generated in the unit 5 and blows it from an ozone blowing pipe upper portion 8a.

In the locker chamber 3, an external ozone killer 32 for introducing external air and preventing ozone leakage is provided.
Is provided. An internal ozone killer 9 that connects the chambers 3 and 4 is provided between the locker chamber 3 and the machine chamber 4, and an exhaust side 31 of an air passage 31 that blows air to the locker chamber 3
A blowing ozone killer 33 is provided in a. Inside the machine room 4, an exhaust pump 35 is provided which sucks the air in the rocker room 3 from the suction pipe 34 through the internal ozone killer 9. The suction pipe 34 is extended near the internal ozone killer 9 in order to improve the suction efficiency.

A three-way valve (not shown) is built in the exhaust pump 35, and a one-through exhaust passage 36 for exhausting the sucked air to the outside of the rocker and a circulation passage 37 for returning to the blower passage 31 on the outlet side of the exhaust pump 35. It is possible to connect and switch freely.

In such a sterilization rocker 30, when the ozone generating unit 5 operates, the compressor 6 operates and sucks the air in the machine room 4. Air to the machine room 4 is sucked from the outside of the rocker in the directions of arrows J and K through the external ozone killer 32, the locker room 3, and the internal ozone killer 9. The air compressed by the compressor 6 is ionized by the ozonizer 7 to become ozone, and is sprayed onto the clothes 2 from the upper part in the rocker chamber 3 in the arrow L direction through the ozone blowing pipe 8. Ozone increases in the locker chamber 3, and the air in the locker chamber 3 is exhausted in the direction of arrow M to the outside of the locker chamber 3 via the external ozone killer 32 and decreases. After a certain period of time, the locker chamber 3 is filled with ozone. The clothes 2 are fully exposed to ozone and sterilized in every corner. At the same time, the interior of the locker room 3 is also sterilized with ozone. still,
The extra ozone in the locker room 3 is the external ozone killer 32.
And is exhausted in the direction of arrow M to the outside of the locker chamber 3. During the sterilization process, even if ozone in the locker chamber 3 tries to enter the machine room 4 side, it is decomposed by the internal ozone killer 9, so that the machine room 4 is not affected by ozone.

When the ozone in the locker chamber 3 is decomposed by the one-through ozone decomposition method after the sterilization of the clothes 2, the three-way valve is switched so that the one-through exhaust passage 36 is connected to the outlet side of the exhaust pump 35 in advance. Keep it.

The ozone generation unit 5 stops the generation of ozone, and the residual ozone in the ozone blowing pipe 8 is removed by the rocker chamber 3.
When exhausted to the inside, the exhaust pump 35 operates, and the ozone in the rocker chamber 3 is decomposed by the internal ozone killer 9 into oxygen. This oxygen is exhausted into the machine chamber 4, sucked into the exhaust pump 35 from the suction pipe 34, and exhausted to the outside of the rocker through the one-through exhaust passage 36. Locker room 3
When the ozone in the inside is decomposed and exhausted into the machine room 4, the inside of the rocker chamber 3 becomes a negative pressure, so that fresh air from the outside of the rocker into the rocker chamber 3 through the external ozone killer 32 in the direction of arrow J. When introduced, a flow in a certain direction from top to bottom occurs, and ozone in the rocker chamber 3 is decomposed in a short time.
Therefore, the sterilized clothes 2 can be safely taken out from the locker chamber 3 after the ozone decomposition.

On the other hand, when the ozone in the locker chamber 3 is decomposed by the circulation type ozone decomposition method, the three-way valve is switched in advance so that the circulation passage 37 is connected to the outlet side of the exhaust pump 35. .

When the ozone generating unit 5 stops the generation of ozone and the residual ozone in the ozone blowing pipe 8 is exhausted into the rocker chamber 3, the exhaust pump 35 is operated, and the ozone in the rocker chamber 3 becomes the internal ozone. It is decomposed by killer 9 into oxygen. This oxygen is exhausted into the machine room 4, is sucked into the exhaust pump 35 from the suction pipe 34, and is circulated in the circulation path 37.
The air is exhausted into the air passage 31 via The oxygen exhausted into the blower passage 31 is exhausted into the rocker chamber 3 from the blowing ozone killer 33 through the blower passage 31. Ozone in the locker chamber 3 is decomposed into oxygen by the internal ozone killer 9 and is exhausted into the machine chamber 4 together with oxygen in the locker chamber 3. Oxygen exhausted into the machine room 4 is a suction pipe 34
Is sucked in by the exhaust pump 35, and is exhausted into the air passage through the circulation passage 37. In this way, the air in the locker chamber 3 forms a circulation path that returns to the locker chamber 3 via the internal ozone killer 9, the suction pipe 34, the exhaust pump 35, the circulation path 37, the air passage 31 and the blowing ozone killer 33. During repeated passage through the internal ozone killer 9, ozone is decomposed and the rocker chamber 3 is depleted of ozone and filled with oxygen. Therefore, after ozone decomposition,
The sterilized clothes 2 can be safely taken out from the locker chamber 3.

Further, an exhaust fan Fd, a damper Dp, and an exhaust duct may be used instead of the three-way valve and the exhaust pump (FIGS. 3B and 3C). As shown in FIG. 3B, when the damper Dp forms a flow path for discharging the air in the rocker chamber 3 to the outside between the ozone killer 9 and the ozone killer 100, the one-through disassembly is performed, and FIG. As shown in c), the damper Dp causes the air in the locker chamber 3 to move.
Circulating ozonolysis can be carried out when forming the flow path returning to the inside.

As described above, according to the present embodiment, it is possible to switch between the one-through decomposition method and the circulation type ozone decomposition method. Therefore, during ozone generation, the exhaust fan (pump) is rotated at a low speed and the inside of the rocker is operated by the one-through decomposition method. With a simple negative seal structure, ozone can be prevented from leaking to the outside of the rocker, and the ozone killer can be miniaturized by using the circulation type ozone decomposition method.

FIG. 4 is a conceptual diagram of another embodiment of the sterilization locker of the present invention.

The feature of this embodiment is that the locker chamber is divided into a plurality of locker chambers, an ozone blowing pipe is provided in each of the rocker chambers, and a valve is provided in each of the blowing pipes. In each locker room, there is a locker room that is "under sterilization", "under ozone decomposition" and "usable".

In the figure, the sterilization locker 40 has three locker chambers of the one-through decomposition method on the left and right in one locker.
The room is divided into compartments, and the machine room is formed below the entire locker compartment.

A set of ozone generating unit 5 is arranged in the machine chamber 41, and a branch pipe 42 whose discharge side is branched in three directions is connected to the ozonizer 7 of the ozone generating unit 5. The outlet of the branch pipe 42 is connected to each of the three valves 43a to 43c. Valve 4
A substantially L-shaped ozone blowing pipe 44a is connected to 3a and guides ozone to blow out from the upper part of the locker chamber 3a that houses the clothes 2a. An external ozone killer 13a that introduces external air from the outside of the locker into the locker chamber 3a and prevents ozone leakage is provided above the locker chamber 3a. Locker room 3a and machine room 41
An internal ozone killer 9a that exhausts the air in the locker chamber 3 into the machine chamber 4 and decomposes ozone from the locker chamber 3 into oxygen is provided between the and. An exhaust fan 10a and a fan cover 11a are provided on the exhaust side of the internal ozone killer 9a. A louver 12a for exhausting the air exhausted into the machine room 41 by the exhaust fan 10a is provided in a portion of the floor 41a of the machine room 41 corresponding to the exhaust fan 11a.

Similarly, a locker room 3b for accommodating clothes 2b
Also in (3c), an ozone blowing pipe 44b (44c) connected to the valve 43b (43c) is provided, and an internal ozone killer 9b (9c) is provided between the rocker chamber 3b (3c) and the machine chamber 41. Has been. Locker room 3b (3
An external ozone killer 13b (13c) is provided above c). An exhaust fan 10b (10c) and a fan cover 11b are provided on the exhaust side of the internal ozone killer 9b (9c).
(11c) are provided. Floor 41 of machine room 41
The louver 12b (12b) for discharging the air exhausted into the machine chamber 41 by the exhaust fan 10b (10c)
c) is provided.

The sterilization locker 40 as described above can independently supply ozone generated in one ozone generating unit 5 to the three locker chambers 3a to 3c by opening and closing the valves 43a to 43c. Moreover, ozone in the locker chambers 3a to 3c can be decomposed independently. That is, the sterilization is performed in each of the rocker chambers 3a to 3c by opening / closing the valves 43a to 43c.
It can be used as a locker room during ozonolysis and during use.

For example, when there are three locker rooms as shown in the figure, the locker room 3a is divided into "under sterilization", the locker room 3b into "under ozone decomposition", and the locker room 3c into "usable". Can be used. In this case, the ozone generation unit 5 is operating, the valve 43a is in the “open” state, the valves 43b and 43c are in the “closed” state, ozone is exhausted to the rocker chamber 3a, and the rocker chamber 3b side is closed. The exhaust fan 10b operates, and the exhaust fans 10a and 10c on the rocker chambers 3a and 3c side are stopped. Although electromagnetic valves are used for the valves 43a to 43c and the opening / closing operation is performed electrically, they may be performed manually. Although the number of locker rooms is three in the figure, it goes without saying that the number of locker rooms may be two or four or more.
