Description

  The present invention relates to a soil decomposing apparatus for deodorizing and sterilizing by decomposing soil using ultraviolet rays or ozone.

  Conventionally, in order to remove the dirt adhered to the flooring and walls in the building, it was wiped off with a cloth with a detergent or the like. However, there are cases where it is difficult to wipe off minute gaps in the flooring and dirt that has entered the fine holes in the wood. Moreover, it was necessary to sterilize the dirt on the wiped cloth itself. Therefore, in order to remove such dirt, the dirt is covered with a sealed space, and ultraviolet light is irradiated on the dirt portion by a germicidal lamp that generates a wavelength having a high deodorizing and sterilizing effect for a certain period of time in this space. In addition, deodorizing and sterilization is performed by supplying ozone having a strong sterilizing action against microorganisms in the air. However, in such deodorization and sterilization, both ozone gas and ultraviolet light are harmful to the human body, so the dirt part is sealed so that they do not leak. I couldn't. Therefore, there are cases where it is difficult to accurately determine at what timing gas injection and ultraviolet light irradiation should be stopped in order to end deodorant sterilization.

By the way, the ozone generated by the germicidal lamp provided in the main body is supplied to two ozone discharge portions that also serve as covers, and the two ozone discharge portions cover the outer periphery of the handheld mop that is contaminated with the sterilized object. A tool sterilization / deodorization device that sterilizes and deodorizes ozone by discharging ozone into the covered space is known (see Patent Document 1). However, since this device disinfects the object to be sterilized by sealing it with the ozone discharge part, it is impossible to grasp the decomposition state of the dirt in the seal, and accurately determine the end of the sterilization work. It was difficult. For this reason, it may take a long time to re-execute sterilization.

  Hereinafter, a soil decomposing apparatus (hereinafter referred to as the present apparatus) according to a first embodiment of the present invention will be described with reference to FIGS. 1 to 3. The apparatus 1 includes a substantially rectangular housing 2 having an opening 3, an ozone generator (ozone generating means) 4 that supplies ozone to an internal space 10 (internal space) of the housing 2, Are provided with an ultraviolet light source part (ultraviolet irradiation means) 5 for emitting ultraviolet rays toward the opening 3 and a window part 6 for viewing the opening 3 from the outside. The ozone generator 4, the ultraviolet light source 5, and the like are connected to an external AC power source via a power cord 50.

(Casing)
The housing 2 includes an internal space portion 10 having an opening 3, a window portion 6, and a bottom surface portion 7 surrounding the opening 3 and in contact with the floor surface A to be deodorized and sterilized. The housing 2 also serves as a support for housing or installing the ozone generation unit 4 and the ultraviolet light source unit 5, and the ozone generation unit 4 and the ultraviolet light source unit 5 face the internal space 10 of the housing 2. It is arranged on one inner surface. Moreover, the housing 2 is installed on the dirt surface B which is the object of deodorization and sterilization on the floor or wall (floor surface A) during the deodorization and sterilization. At this time, when the internal space portion 10 covers the dirty surface B, the bottom surface portion 7 is brought into contact with the floor surface A with the dirty surface B, and the internal space portion 10 and the floor surface A form a substantially sealed space. By supplying and emitting ozone and ultraviolet rays from the ozone generation unit 4 and the ultraviolet light source unit 5 in this sealed space, the dirt on the dirty surface B is decomposed and deodorized and sterilized. In addition, as a member of the floor surface A to be deodorized and sterilized, all types of floor materials in general houses such as flooring, carpets, and tatami mats are targeted.

  The window 6 is disposed on the upper surface of the housing 2 at a position where the light emitted from the ultraviolet light source 5 is reflected by the floor surface A including the dirty surface B facing the opening 3. The window 6 is provided with a translucent member 61 that transmits visible light that is excited by absorbing the ultraviolet light emitted from the ultraviolet light source unit 5 by the dirt surface B and cuts the ultraviolet light. Thereby, when covering the floor surface A with the housing | casing 2, the user can observe the dirt surface B located in the opening 3 of the internal space part 10 visually, and does not receive the unnecessary irritation | stimulation by an ultraviolet-ray. Further, the visible light excited by the dirt is emitted in the direction of the window part 6 where the light emitted from the ultraviolet light source part 5 is reflected.

(Ozone generator)
The ozone generation unit 4 generates ozone by applying a high frequency high voltage between opposed electrodes to ozonize a part of the air, for example, and deodorizing and sterilizing by decomposing dirt with ozone. . The ozone generator 4 sprays ozone gas in a substantially sealed space formed by installing the internal space 10 on the floor surface A. This ozone gas is filled in a substantially sealed space, the ozone concentration is increased, the dirt on the dirty surface B of the floor surface A is decomposed and deodorized and sterilized.

(UV light source)
The ultraviolet light source unit 5 generates a wavelength having a high deodorizing and sterilizing effect, and an ultraviolet light for deodorizing and sterilizing is used as the light source. From the light source of the ultraviolet light source unit 5, either one of ultraviolet rays having a peak at 100 to 280 nm (UV-C) or ultraviolet rays having a wavelength component of 280 to 315 nm (UV-B) is contained in the internal space. The light is emitted into a substantially sealed space formed by the portion 10 and the floor surface A, and the dirt surface B is irradiated. This ultraviolet ray for deodorizing and sterilizing has different deodorizing power and sterilizing power depending on the wavelength classification, and the ultraviolet ray (U · V-C) is required when strong deodorizing and sterilizing is required. Used when you do not want to damage the floor. In addition, the ultraviolet light is ultraviolet light that excites visible light by being irradiated and absorbed on a soiled portion made of urea, ammonia, or the like. Therefore, by irradiating the dirt part with ultraviolet rays, visible light is excited and emitted to the outside through the window 6, so that the user can visually recognize the dirt part with the visible light.

  Each inner surface of the internal space portion 10 irradiated with ultraviolet rays of the housing 2 is formed of a member that easily reflects ultraviolet rays. Examples of the reflective member include metal members (stainless steel (eg, SUS304), aluminum, anodized, etc.), metal surface treatments (chrome plating, aluminum deposition, gold plating, gold deposition, silver plating, silver deposition products, etc.) and resin molding. Products (molded metal flakes containing a metal such as aluminum in a resin) can be used. However, the translucent member 61 of the window portion 6 is a member that can transmit visible light.

  Moreover, since each inner surface of the internal space part 10 is filled with ozone in the internal space part 10, it is formed of a member that is not easily deteriorated by ozone. Examples of the members that are not easily deteriorated by ozone include metal members (stainless steel such as SUS304, aluminum whose surface is anodized), general porcelain, alumina porcelain, engineering plastic / polyimide resin (for example, DuPont Vespel). In addition, Kapton film manufactured by Toray DuPont Co., Ltd.), PEEK (polyetheretherketone) resin (eg, Vectra manufactured by Victrex MC, Inc.), and the like can be used. However, the translucent member 61 of the window portion 6 is a member that can transmit visible light.

  The procedure of deodorizing and sterilization using the apparatus 1 configured as described above will be described. First, the user finds the position of the dirty surface B in advance by visual observation or the like. Next, the inner space portion 10 covers and seals the floor surface A including the dirty surface B, thereby forming a substantially sealed space by the inner space portion 10 and the floor surface A. In this substantially sealed space, the ozone generator 4 is turned on to generate ozone to be filled, and at the same time, the ultraviolet light source unit 5 is turned on to emit ultraviolet light L1 (UV-B or UV-C) for deodorizing and sterilization. To do.

  The ultraviolet light L <b> 1 from the ultraviolet light source unit 5 is emitted in a direction facing the opening 3 in the substantially sealed space and irradiates the dirt surface B positioned in the opening 3. Moreover, the ozone gas generated from the ozone generator 4 is filled in the substantially sealed space of the internal space 10 in a few seconds. In the substantially sealed space, when the ultraviolet ray L1 is irradiated and the ozone gas continues to be filled, the dirt is gradually decomposed from the dirt surface B by the action of the ultraviolet ray L1 and ozone. At this time, the visible light L2 is excited by absorbing ultraviolet rays from the undecomposed dirt portion of the dirt surface B. With this visible light L2, it is possible to confirm the state of disassembly of dirt on the dirt surface B from the window portion 6. Therefore, when the decomposition of the dirt can be confirmed, the power is turned off, the ozone generation unit 4 and the ultraviolet light source unit 5 are stopped at the same time, and the dirt decomposition work is finished.

  As described above, according to the present embodiment, the window 6 provided in the housing 2 transmits the visible light L2 excited by absorption of the ultraviolet light L1, and cuts the ultraviolet light L1. In a state where the case 2 is covered with dirt, the state of decomposition of the dirt can be easily confirmed visually and safely without receiving unnecessary stimulation. As a result, the decomposition state can be always grasped, and it can be accurately determined at which timing the injection of ozone gas and the irradiation of ultraviolet light should be stopped.

  Moreover, since the window part 6 is arrange | positioned in the direction position in which the light radiate | emitted from the ultraviolet light source part 5 is reflected by the floor surface A, the visible light L2 excited by dirt absorbing the ultraviolet-ray L1 is received. It can be efficiently transmitted to the window portion 6, and the decomposition of dirt can be confirmed with high accuracy.

  In addition, by forming each inner surface of the internal space portion 10 irradiated with ultraviolet rays with a member that easily reflects ultraviolet rays, the reflection efficiency of the inner space portion 10 inner surface with respect to ultraviolet rays is increased, and the ultraviolet rays are concentrated on the dirt surface B. Therefore, the deodorizing and sterilizing treatment can be performed efficiently and in a short time. Moreover, since the ultraviolet rays can be reflected by the inner surface of the internal space portion 10 to be difficult to absorb, deterioration of the constituent members due to the ultraviolet rays can be prevented.

  Further, by forming each inner surface of the internal space portion 10 filled with ozone with a member that is not easily deteriorated by ozone, for example, when ozone is sprayed at a high concentration in order to efficiently perform a soil decomposition treatment, Even when the soil decomposition by the soil decomposition is performed for a long period of time, the member can be used safely without deterioration.
