Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a toilet unit with an air purifier.

Recent semiconductor production factories and precision machinery assembly factories.

In food processing factories, pharmaceutical manufacturing factories, etc., work rooms are designed to reduce the number of airborne dust and bacteria in order to prevent dust and bacteria floating in the air from affecting product performance. This is a so-called clean room lamination facility.

Increasingly,

However, in conventional relatively small-scale clean rooms, no clean room-specific upgrades have been installed. For this reason, every time a worker inside a clean room needs to relieve himself, he wears dust-free clothes in a semi-clean room set up between the clean room and the outside, changes his clean room canvas shoes to semi-clean room footwear, and then After changing into outdoor footwear outside the semi-clean room, use the external toilet. After using the toilet, change into semi-clean room footwear, enter the clean room, change into clean room canvas shoes, put on dust-free clothing, remove dust with an air shower, etc., and then enter the clean room. In this way, workers in the clean room have to take time-consuming actions every time they use the toilet, which makes them feel psychologically burdened, and the current situation is that there is a lot of wasted time in the production process.

The present invention aims to eliminate the time-consuming actions that workers in clean rooms had to take, and provides a toilet unit that can be easily installed adjacent to a VC in a clean room or in a semi-clean room. The main point of this system is that in a toilet unit that houses a flush toilet, a washbasin, etc., an air intake port with an air filter attached to the ceiling wall and an air exhaust port located at the bottom of the wall.

Embodiments of the present invention will be described below with reference to FIGS. 1 to 4.

(W) Install a door 2 on the frame 1 made of FRP (reinforced plastics) or plywood, etc. of the unit, align the door 2 with the opening of the clean room wall 25, and install the frame 1 adjacent to the clean room wall 25. Then, an air intake port 8 is provided in the ceiling wall of the frame 1, an air filter 10 for dust removal and sterilization is provided above it, and an air filter casing 11 that covers the air filter 10 is further provided above. An air introduction pipe 12 is connected to the upper surface of the air filter casing 11, and an air outlet 9 is provided at the bottom of the side wall of the frame 1.A flush toilet 4 is installed in the flush chamber 3 inside the frame 1. fi11 Wall-mounted hand wash basin 5 with foot-operated faucet, automatic hand dryer with air filter (e.g. photoelectric operation) 6, cosmetic mirror 14. Detergent container 15
, and then install an adhesive pine door on the door 29111 on the floor. A water pipe for a flush toilet 21 and a drain pipe for a flush container 22 are connected to the flush basin 41 and the wash basin 5 through joints, respectively. Connect the handwash basin water supply v231 handwash drain pipe 24 connected to the sterilizing filter.

To explain the functions of the toilet unit constructed as described above, air sent from a blower and preliminarily dedusted with a buri filter or the like is introduced into the air filter casing 11 through the air introduction pipe 12. If the amount of air being blown is large, use an air duct.

The air introduced into the air filter casing 11 is dedusted and sterilized by the air filter 10, and is then introduced into the washing chamber 3 as clean air. The air is completely discharged through the air outlet 9 provided at the bottom. The air discharged from the air outlet 9 may be blown into a blower or discharged into the atmosphere.

Next, to explain the case where a worker in a clean room uses this toilet unit, when the worker opens the door 2 and enters the flush room 3, the inside of the flush room 3 is in a clean air condition. There is no contamination of dust and sludge into the clean room by the air.

After the door 2 is closed, if dust is generated in the washing chamber 3 due to putting on and taking off clothes, etc., the dust and bacteria will quickly ride on the flow of clean air and be discharged from the air outlet 9. returns to clean air condition. A washing room in which the hands are washed by stepping on the water tap pedal 16 in the handwash basin 5 and then drying the hands with an automatic hand dryer 6 equipped with an air filter to prevent dust and bacteria from adhering to the hands. When exiting from door 3, step on the sticky pine door, remove dust from the soles of shoes, open door 2, and exit.

In this case as well, the inside of the washing room 3 is in a clean air condition, and there is no dust removed from the soles of shoes and no dust or bacteria attached to hands, so that no dust or bacteria contaminates the clean room.

In addition, if you want to further reduce the amount of dust generated in the flush room 3, you can reduce dust by using a shower wash/dry flush toilet, and if you want to prevent people from sitting on the birch handle, the automatic Use opening/closing doors. Further, the air to the toilet unit may be either continuous air blowing or intermittent air blowing depending on the usage, but from the viewpoint of energy saving, the minimum necessary air volume is desirable. Furthermore, if it is desired to indicate when the toilet unit is in use, it is advisable to provide an automatic indicator lamp (for example, an automatic photoelectric type). Figures 5 to 8 show actual examples of the present invention, in which a part of the air filter of the embodiment shown in Figures 1 to 4 is replaced with an air filter unit incorporating a blower. It is something.

That is, the blower built-in air filter unit 30 has the blower 29. It has a structure in which an air filter 26 for removing dust and bacteria is incorporated in an air filter casing 27 VC, and air that has been removed by a pre-filter etc. is sucked in through an air intake port 28, pressurized by a blower 29, and the air filter 26 removes dust and bacteria. , which blows air into the washing chamber 3.

Therefore, the present invention achieves the effect described in F since it has a structure in which an air intake port with an air filter attached to the ceiling wall portion is provided and an air discharge port is provided in the lower part of the side wall.

1. Since the toilet unit of the present invention is configured to maintain clean air inside the room, it can be installed adjacent to the clean room so that workers in the clean room can directly enter and exit from the clean room. It can be used immediately through the door of the toilet unit.

Furthermore, if it is not possible to install the vrC1 directly in a clean room, it can also be installed in a semi-clean room.

In the case of Izuba, workers can relieve themselves without taking off their dust-free clothes, which eliminates the traditional labor-intensive action, eliminates psychological distress, and saves time. It becomes possible.

2. Since it is a unit, it can be easily installed in a new or existing clean room.

3 Since it is unitized, factory production is possible.
It can be supplied as an inexpensive product with stable quality.

4. Previously, people had to go out of the clean room and use external locations every time they needed to use the toilet. For this reason, clean room entry records,
There is also a large amount of work involved in managing the cleanliness of the 11-room, such as recording work hours. By using a single-clean room unit, it is no longer necessary to go outside the clean room to relieve oneself, making it possible to significantly reduce cleanliness management work.
