Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for deodorizing and sterilizing a space divided into offices (offices), etc.
In particular, the present invention relates to a deodorizing / sterilizing device suitable for a building having a plurality of compartments for deodorizing / sterilizing.

[0002]

2. Description of the Related Art When deodorizing / sterilizing a conventionally partitioned space, for example, a living room (office office, storage room, hotel room, each section in public facilities, etc.), a deodorizing solution and a sterilizing solution are used. Nozzle spray or a method using ozone is used. Ozone deodorization and sterilization equipment emits ozone air generated by high-voltage discharge to the space to be treated at night or on holidays when people are gone, and uses the strong oxidizing power of ozone to sterilize the interior of the living room. Deodorizing is performed.

[0003]

However, the deodorizing and sterilizing apparatus using ozone has the following problems to be solved.

(1) Since the ozone treatment after release depends on natural attenuation (diffusion) of ozone, there is concern about safety in the human body and living room. (2) No consideration is given to erroneous release of ozone while a person is in the room or accidental entry of a person during release of ozone. (3) Since ozone is released by one system to one target space for sterilization and deodorization, an ozone generator is required for each target room (space) when there are multiple or wide areas. Therefore, the initial cost increases. (4) Ozone is released when there are no people at night, so the device is not used during the daytime and the utilization efficiency is poor.

Therefore, an object of the present invention is to provide a deodorizing / sterilizing device for a compartment space which can ensure safety while using ozone.

Another object of the present invention is to provide a deodorizing / sterilizing device for a compartment space which can reduce the initial cost.

[0007]

In order to achieve the above object, the present invention provides an ozone generator for generating ozone air, a pipe for guiding the ozone air to a compartment space in a building, and a supply port communicating with the compartment space. Air supply duct that is laid so as to provide external air to the air supply duct, an exhaust duct that is installed so that the suction port communicates with the compartment space, and ozone air is provided through the exhaust duct. An exhaust fan for exhausting the exhaust gas is provided, and the air supply fan and the exhaust fan are operated for a fixed time after the ozone generator is operated for a fixed time.

The ozone generator and the fans can be operated at night.

The operation of the equipment at night can be started on condition that the illumination switch of the compartment space to which ozone is supplied is off.

Further, the pipe, the air supply duct, and the exhaust duct are laid in each of the plurality of compartment spaces, and an electromagnetic valve is provided in the middle of the pipe for each compartment space, and the air supply duct and the exhaust duct are further provided. A motor damper may be provided at each of the air supply port and the air intake port.

In this case, the solenoid valves may be sequentially operated for a fixed time, and after this operation, the motor damper installed in the partitioned space may be opened for a fixed time.

[0012]

According to the above-mentioned means, ozone air from the ozone generator is sent to the partitioned space through the pipe for a certain period of time to deodorize and sterilize the space. After this, the outside air from the air supply fan is supplied to the space filled with ozone through the air supply duct, and the exhaust air sucks the ozone air in the space from the exhaust duct.
Discharged outside the building. Therefore, after deodorizing and sterilizing the space, ozone air that may affect the human body can be quickly discharged from the space, and safety can be ensured even if ozone is used.

If the equipment is operated at night, deodorization and sterilization by ozone can be performed when a person is absent, such as in an office, so that safety is surely secured.

Further, when the equipment is in operation, it may be in the room even at night, and it may not be possible to confirm it each time. Therefore, pay attention to the fact that the room is always illuminated at night, and the device is not operated when the light switch is on. As a result, the person in the room does not have a risk of coming into contact with the ozone air, and safety is ensured.

When deodorizing and sterilizing a plurality of compartment spaces in a building, ozone air can be selectively supplied by providing solenoid valves corresponding to the plurality of compartment spaces, and By providing a motor damper for each of the air supply port and the exhaust port for each space, it becomes possible to select and ventilate each partitioned space. As a result, it is possible to deodorize and sterilize multiple rooms while using an ozone generator with ozone air generation capacity for one room (one compartment space), and to reduce the size of the ozone generator and reduce equipment costs. You can

Further, after the solenoid valve corresponding to a certain compartment space is operated, a pair of motor dampers corresponding to the compartment space deodorized and sterilized by the solenoid valve are operated, so that 1 after deodorization and sterilization is performed. Ventilation is performed due to room delay. Therefore, it becomes possible to quickly ventilate after deodorization and sterilization, and enhance safety.

[0023] Normally, there are no people in the room 23
At time, the control unit 12 is driven so that the ozone generator 5 is turned on. At the same time, the control unit 12 switches the solenoid valve 3c to the open state and switches each of the motor dampers 7a, 7b, 7c, 9a, 9b and 9c to the closed state. By this control, ozone generated by the ozone generator 5 is discharged into the chamber 1c through the route of the header 4 → the solenoid valve 3c → the pipe 2c. This ozone release is performed over two hours until 1:00 am on the next day.

At 1:00 am, the control unit 12 keeps the ozone generator 5 turned on and supplies the air to the fan 8 and the exhaust fan 11.
The solenoid valve 3b is switched to open, the solenoid valve 3c is switched to close, and the motor dampers 7c and 9c are switched to open. By this control, the object of deodorization / sterilization by the ozone generator 5 is moved from the chamber 1c to the chamber 1b. At the same time, the outside air from the air supply fan 8 is supplied only to the room 1c through the motor damper 7c, and the ozone in the room is discharged to the outside of the building in the process of being sucked from the motor damper 9c, so that the ozone is prevented from remaining.

Next, at 7 am, the control section 12 turns off and closes all the devices. That is, the ozone generator 5, the air supply fan 8, and the exhaust fan 11 are turned off, all the solenoid valves 3a, 3b, 3c are closed, and the motor dampers 7a, 7b, 7c, 9a, 9b,
All 9c are opened, and deodorization / sterilization treatment and indoor ventilation treatment are completed.

In the above embodiment, the deodorizing / sterilizing process is performed for each room, but if the ozone generator 5 can be made large, ozone can be supplied to a plurality of rooms at the same time. It is possible.

By the way, it is a safety problem to release ozone while a person is present in any of the chambers 1a, 1b and 1c. Therefore, it is required to prevent erroneous release of ozone while the user is in the room. A control example for this will be described with reference to FIG.

FIG. 3 is a flow chart showing the control for preventing erroneous release of ozone. First, when a start button (not shown) of the operation panel 13 is operated, a processing start command is issued (step 301). After this command, when it is determined that the start time (23:00) shown in FIG. 2 has been reached (step 302), it is determined whether or not the lighting switch of the target room for deodorization / sterilization processing is on. (Step 303). If the lighting switch is turned on, it can be determined that there is a person in the processing target room, and the operator of the operation panel 13 displays a text message such as "there are people" or turns on the warning lamp ( Step 304).

On the other hand, if the lighting switch is off, it is determined that there is no person, and the solenoid valve corresponding to the processing chamber is controlled (from closed to open) (step 305).
At the same time, the ozone generator 5 is turned on (step 30).
6). Further, a warning is given by a buzzer or the like so that a person who enters the room thereafter can be warned that ozone is being released (step 307). After that, the series of controls shown in FIG. 2 is executed.

In addition, the ozone generator 5 may be powered from the midnight power source, and the ozone generator 5 may be unilaterally stopped at a certain time. The running cost can be reduced by using the midnight power.

If an ozone generator 5 capable of generating both ozone air and ozone water is used, it is used as floor cleaning water for the kitchen during the daytime and deodorizes ozone air at night.
It can be used for sterilization treatment, the equipment cost can be reduced, and the utilization efficiency of the equipment can be improved.

Further, in the above-mentioned embodiment, the processing target is three chambers, but it can be arbitrary as long as the number of solenoid valves and motor dampers is increased.
