Description

The present invention uses ultraviolet rays to deodorize and sterilize air only by ultraviolet rays, and deodorize and sterilize only by ultraviolet rays and a photocatalyst, and at the same time, ultraviolet rays illuminate a phosphor to emit a desired light, and the structure described above The present invention relates to an apparatus for adding a new scent to air purified by the above method.

Conventionally, deodorizing and sterilizing equipment for air only by ultraviolet rays, deodorizing and sterilizing equipment combining ultraviolet rays and photocatalysts, deodorizing and sterilizing equipment using a combination of both, lamps that provide favorite lights, and devices that provide favorite scents Exist as separate products. There is also an apparatus that integrates the above-described functions using ultraviolet rays devised by the present inventors.

Japan's living room is small, and there were problems in installing separate deodorizing and disinfecting devices, lamps that provide the light of your favorite color, and devices that provide your favorite fragrance.

In addition, a device using a paint-type photocatalyst that integrates a deodorizing and sterilizing function devised by the present inventor, a light of a favorite color, and a function of evaporating a favorite fragrance, has a satisfactory deodorizing ability, a uniform light, and short In addition to providing evaporation of fragrance over time, the evaporating dish that generates fragrance requires water, and there is a risk of spilling water when replenishing water.

Moreover, when a photocatalyst having a large specific surface area is simply stacked, the transmission of ultraviolet rays is hindered, and practical brightness cannot be provided.

An object of the present invention is to provide a small integrated device that deodorizes and disinfects air, lights a favorite color, and evaporates a favorite fragrance in a short time.

In order to achieve the above object, an air deodorizing and sterilizing apparatus according to the present invention includes an ultraviolet lamp in a passage of air sucked from an intake port, and passes the ultraviolet light and air around the ultraviolet lamp to provide a photocatalyst. A container that can be stored is provided, the photocatalyst is disposed so as to be stacked on the container, and the sucked air is discharged while being in contact with the photocatalyst.

In addition, in order to pass a part of the ultraviolet rays and let the air sucked at the same time contact with the photocatalyst, it is made into a container shape with a net or a plate with many holes, and a photocatalyst with a large specific surface area is taken from the cross section in the container. It is characterized by being arranged in a single layer or a staggered pattern.

Further, the invention is characterized in that a cylinder holding a phosphor that emits light by ultraviolet rays is provided outside the container for storing the photocatalyst.

Further, the present invention is characterized in that an evaporating dish having a vent on the side surface is provided at the exhaust port of the purified air.

In the air deodorizing and sterilizing apparatus of the present invention, the function of evaporating air in a short time can be made into a compact apparatus by integrating the deodorizing and sterilizing of air with the light of the favorite color and the evaporation of the favorite fragrance in a short time.

Since the sucked air has an increased area in contact with the photocatalyst (7) arranged so as to be piled up in a superimposed manner, the deodorizing effect is 30 compared with a device in which the photocatalyst devised by the present inventors is arranged in a plane. % Or more (FIG. 7).

In addition, the ultraviolet rays that illuminate the phosphors pass through the gap (8) through the photocatalyst arranged in a single layer or a staggered pattern as viewed from the cross section, so that the amount of light is increased and the unevenness of light is reduced. It can emit light with less light and enhance the healing effect.

In addition, evaporation using the purified air flow increases the amount of fragrances evaporated and provides the desired fragrance in a short time. In addition to eliminating the risk of spilling water, accidentally spilling large amounts of fragrance into the evaporating dish will not leak from the evaporating dish.

Thus, the functions conventionally provided as a single product can be realized by a single small device, and further, the device of the present invention can be placed on the bedside of the bedroom and used as a night light.

Moreover, since this small apparatus does not require a large installation area, it can be used by simply moving from room to room.
