Description

DETAILED DESCRIPTION OF THE INVENTION [Objective of the Invention] (Field for IJ on local chestnuts) This invention relates to a deodorizing and sterilizing device for odor-producing and bacterial growth areas.

(Prior art) Conventionally, sterilization methods used in places such as food processing plants, where it is necessary to avoid contaminating the surface of Kaloe food with fallen bacteria, floating bacteria, etc., involve keeping the entire processing room in a sterile state. There were two methods: the clean room method, and the clean booth method, where only the area where processing was to be performed was enclosed in a sterile state, using ultraviolet light, ozone, etc. for sterilization.

(Problems to be Solved by the Invention) [7] The above-mentioned clean room method requires equipment costs in the order of tens of millions of yen, and even the clean puska method requires equipment costs in the order of several million yen.

In addition, even if you know that ultraviolet light is used for sterilization, you may not know the amount of ultraviolet light (the product of ultraviolet irradiation intensity and ultraviolet irradiation time) or the distance between the object to be sterilized and the ultraviolet source. Lack of knowledge regarding its relationship with sterilization has led to the misconception that ultraviolet rays are less effective, and ozone is more effective than ozone required for sterilization.
Ozone that humans can withstand in the working environment! Once is part 1
130 0. / ppm or less, and at the # degree required for sterilization, the odor of ozone special M can be lingering, causing headaches, and there is no ozone odor and staining the eyes of workers. In some cases, they are used in an atmosphere that has no sterilizing power, and in the end, they are used in an atmosphere that does not have sterilizing power.

In view of the above facts, this invention decomposes oxygen 02 in the air and generates powerful ozone 3.
An ozone lamp that intensively emits a wavelength of 0.0 nm (usually called an oscilloscope), and an ozone lamp that emits 0. An ultraviolet lamp that intensively emits ultraviolet rays with a wavelength of 3.7 nm (usually referred to as germicidal radiation) that decomposes oxygen into oxygen 02 and active oxygen ○ is installed in one Lang chamber, and these 2 By using different lamps, you can prevent odor, bacterial growth (meaning that bacteria are not consciously cultivated, but are increasing against your will), location, tide,
1. For example, make the kitchen, meat, or fishery 7111 factory, etc., strong and complete during times when there are no workers, and create a tolerable working environment for the workers during times when workers are present for approximately 2 consecutive hours. The purpose is to provide an inexpensive device that can deodorize and sterilize areas where odor and bacteria grow.

[Structure of the invention]

(Means for Solving the Problems) The deodorizing and sterilizing device for odor-emitting and bacterial growth areas according to the present invention has the following features:
An ultraviolet lamp a that emits germicidal radiation and an ozone lamp b are installed in a closed lamp chamber A that is suspended in a place where odor is generated and bacteria grow.
/ 0, and a ventilation fan / 2 is installed at the small end l/ of the other power source, respectively, and the ultraviolet lamp a and the ozone lamp b are switched by a changeover switch B and turned on by energizing [7]. .

(Implementation required) The structure of the odor generating, bacterial growth area deodorizing and sterilizing device according to the present invention will be explained in detail based on an illustrated embodiment.
As shown in the figure, odor generation: Inside the bacterial growth station, a ceiling section λ is placed at the bottom of a rectangular frame that can be suspended at
A rectangular lamp chamber A having a shape is formed as follows. That is, as shown in FIG. 3, at the lower edge 3' of one side wall 3 forming the lamp chamber A, the bottom wall of the lamp chamber A≠
A lid plate B having an angular cross section that forms another side wall j facing the side wall 3 is pivoted at one side of a portion forming the bottom wall 7 to form the other side wall j. The free part m5' of the part is formed so that it can be fixed to the part ♂ of the rectangular frame body /, for example, with a screw r', and the one-force edge 9 (
(see Figure 1), a ventilation fan/2 is provided at the other edge 11, a glass window/3 is provided at the bottom wall, and an ultraviolet lamp a and an ozone lamp are provided at the ceiling 2. A lamp b is detachably provided, and the ultraviolet lamp a and the ozone lamp b can be switched and energized by a changeover switch B (see FIG. 6).

In addition, the ends 4# of each lamp a, b, and the holder/7 are the fifth
As shown in the figure, the support metal body/
An upper surface support piece lj and a lower surface support piece /otsu are provided at ≠ so that the lamp can be moved in and out in the horizontal direction, and care is taken to prevent natural fall to the lower blade.

FIG. 2 shows an example of an Ifs diagram for switching between the ultraviolet lamp a and the ozone lamp b.

(Function) Since this embodiment has the above-mentioned configuration, for example, there are no workers in the factory where there is sunburn, odor, and bacteria growth.
If you want to completely deodorize (7. or completely sterilize) the area until tomorrow morning, put the plug C into the '1 source in Figure 6, and the ventilation fan 7.2 in the lamp chamber A will stop rotating. Then, in order to operate ozone lamp b, set changeover switch B to ozone lamp ON, and relay Mc will work, turning only terminals yellow and 2 of the ozone lamp ON, ozone lamp b will emit light, and lamp chamber A will be ventilated. Odors and dirt in the air where bacteria grow are sucked through the galarita by fan 2, which is excited by an ozone lamp b that intensively emits ultraviolet rays and wavelengths of 4t and 5'nm, and is converted into ozone 0.
Therefore, inside the lamp tA, the air is not completely deodorized and sterilized, but due to the action of the ventilation fan/2, the odor is emitted.
The concentrated (fp)
(pm or higher) ozone makes the atmosphere of the place odorless and sterile.

Ozone is mostly consumed in the decomposition of organic matter in places where there are a lot of oils, fats, proteins, odors, etc., such as in meat and fish processing plants, and has almost no effect on the human body. [7, Tomorrow morning, a little before the factory starts, switch B to turn on the ultraviolet lamp. Relay MO works, and then turn on the terminal of ultraviolet lamp A (7, Since the terminal is turned off,
Ozone lamp B went out, and now it was time for ultraviolet light 2! ;3.7
The ultraviolet lamp A, which intensively emits wavelengths of nm, emits light and is sucked into the lamp chamber A by the fan 7.2.
The ozone O3 in the air that has already been sterilized and deodorized but is rich in ozone at the place where bacteria grow is decomposed into oxygen 02 and active oxygen 0, creating an oxygen-rich atmosphere in the place where the odor is generated and the art gallery N. This not only prevents workers from feeling uncomfortable due to ozone odors and headaches, and from causing eye irritation due to concentrated ozone, but also prevents organic matter from turning into carbon dioxide due to active oxygen. (7) It is possible to maintain a good working environment for workers.

If you want to automatically operate the ultraviolet lamp A during working hours and the ozone lamp B during non-working hours using changeover switch B for 21 hours continuously, use the changeover switch as shown in Figure 7. B has an all-day timer (21
If you want to operate either lamp for a desired time, for example, 77 hours, you can use a time dial timer T2 as shown in Figure R. Bye.

In addition, using an ozone lamp that can generate ozone concentration / θppm, a test was carried out by wiping the surface of the cooking table for meat and fish at the end of the previous day's work at a lunch box and delicatessen processing company, and then the ozone lamp was lit in the lamp room and the next morning. The results of an experiment conducted over a total of 6 days in which the lights were turned off at 5 o'clock and wiped off were as shown in the table below.

Wiping test l-A (center of the workbench, directly below the deadlight) When replacing the lamps (a, b), remove the screws f/ and insert the cover plate O, which has a cross-sectional shape, as shown in Figure 3. Open it and do it.

Furthermore, the glass window /3 is only for checking whether the lamps (a, b) are lit.

〔Effect of the invention〕

This invention has the configuration and operation as described above, and can almost completely deodorize and sterilize areas where odors and bacteria grow during non-working hours, for example at night, using a device with a simple configuration. However, during working hours, for example during the day, when workers are working in places where bacteria grow, such as cooking rooms, food roasting factories, meat and seafood processing factories, hospital waiting rooms, drug processing, etc. When there are people in the area, it is possible to decompose the ozone, which is abundant in the area, into oxygen and activated carbon, creating an atmosphere where workers can legally work, at an equipment cost of several hundreds of thousands of yen. There are noticeable effects that can be done.
