Description

  The present invention relates to a groove on the side of a road to which a groove cover such as a grating (hereinafter simply referred to as a groove cover, including the grating in this specification), a road crossing groove, a food factory, a kitchen, etc. The present invention relates to a sterilization apparatus for sterilizing the inside of the drainage grooves of the floor drainage equipment (the side grooves and the drainage grooves are simply referred to as drainage grooves in this specification).

  Speaking of grating as an example of the groove cover, most of the grating is made of steel, and it is mounted on the same steel receiving frame attached to the side groove of the roadside or the drainage groove of the floor drainage equipment, but it is installed without gap in the receiving frame It is difficult to do this, and when a part of the vehicle floats up from the receiving frame and the vehicle travels or a pedestrian walks, the grating hits the receiving frame and tends to generate a rattling sound. In order to prevent looseness, a metal mat or rubber mat is interposed between the grating and the receiving frame (Patent Documents 1 and 2).

  In the drainage ditch where the groove lid is installed, the flowing water may stagnate or the accumulated organic matter may decay and generate a strange odor. In food factories, the propagation of germs in floor drainage facilities is particularly unsanitary, This is a problem in food hygiene management.

It is known that ultraviolet irradiation and photocatalyst are effective as countermeasures against various germs. Using this, kitchen garbage crushing equipment and toilets are equipped with LED germicidal lamps to irradiate ultraviolet rays, It has been proposed to attach a photocatalyst functional body to the inner surface of the floor drainage structure and sterilize it by irradiating it with light, and to decompose organic matter to remove dirt from the drainage groove (Patent Documents 3 to 3). 5).

According to the third aspect of the present invention, it is possible to sterilize the groove cover and remove the dirt on the groove cover due to the decomposition action of the organic matter.
According to the fourth aspect of the present invention, the ultraviolet irradiation and the sterilization action by the photocatalyst can be combined to enhance the sterilization action in the drain and the organic substance decomposition action.

Hereinafter, a sterilizer according to an embodiment of the present invention will be described with reference to the drawings.
FIG. 1 shows a grating 2 as a groove cover attached to a drainage groove 1, and the grating 2 is of a known structure, for example, steel, and a main member 2a and an auxiliary member 2b made of a twist bar are arranged in a lattice shape. It is a combination, and an anti-rattle material in which a pressing piezoelectric element is incorporated in the step 3 at the upper edge of the opening of the drainage groove 1, preferably an elastic mat 4 made of synthetic resin or rubber is interposed so as not to be loose. It is attached to. The mat 4 is attached to the base plate 5 fixed to the side edge of the grating 2 with bolts, screws, rivets, adhesive or double-sided adhesive tape, or attached to the step 3 of the drainage groove 1 with adhesive or double-sided adhesive tape. Alternatively, it is simply placed between the step 3 and the base plate 4 without being fixed to either the base plate 5 or the step 3.

The pressing piezoelectric element generates electricity when a load is applied by a vehicle or a pedestrian passing on the grating 2, and when the load is removed, the generated electric energy is stored in a capacitor or battery (not shown). It has become so.
As shown in FIG. 2, the elastic mat 4 is provided with a germicidal lamp 6 made of LED at the side end on the drainage groove side so as to protrude into the drainage groove at equal intervals in the longitudinal direction of the drainage groove 1. Each germicidal lamp 6 is connected to the condenser or battery, and the condenser or battery is used as a power source so that ultraviolet rays can be continuously irradiated into the drainage groove.

  In the structure shown in FIG. 3, the germicidal lamp 6 described above is projected obliquely downward from the elastic mat 4 so that the ultraviolet light is irradiated to the drain groove side wall and the bottom wall.

  In the embodiment shown in FIG. 4, as shown in FIG. 5, a thin plate 8 made of, for example, a steel plate, a synthetic resin, or rubber with the germicidal lamp 6 attached at regular intervals in the longitudinal direction is hooked on the auxiliary member 2 b in the center of the grating 2. A sterilizing lamp 6 and a capacitor or a battery (not shown) supported by a hanger 9 and connected to a piezoelectric element are connected by a conductive wire 10.

  6 and 7 show another example of the germicidal lamp attached to the thin plate. The germicidal lamp 6 is attached to the thin plate 12 in the longitudinal direction of the thin plate in order of downward, diagonally downward to the right, and diagonally downward to the left. As shown in FIG. 7, ultraviolet rays can be continuously and uniformly radiated from the germicidal lamp 6 connected to a capacitor or a battery (not shown) into the drain groove.

  The germicidal lamp 6 of the above embodiment is fixed laterally, downwardly, or obliquely downwardly, but is attached to the thin plates 8 and 12 via, for example, a ball bearing connected to the elastic mat 4 and the conductive wire 10. In this case, the germicidal lamp 6 can be oriented and directed in an arbitrary direction.

  In the embodiment shown in FIG. 8, the germicidal lamp 6 protrudes obliquely downward from the elastic mat 4, and the hanger 13 that is supported by being hooked on the auxiliary member 2 b in the center of the grating has a plate 14 with a photocatalyst attached to the entire surface. Is supported by being landed on the bottom of the drainage groove 1. The plate 14 is irradiated with ultraviolet rays from the germicidal lamp 6, but is irradiated with light that is emitted from the condenser or battery provided separately from the germicidal lamp 6, or illumination light such as a sun lamp, kitchen, or food factory. The bactericidal action is also performed.

  In another embodiment, a photocatalyst is attached to the surface of the germicidal lamp 6, and in another embodiment, a photocatalyst is attached to the surface of the grating 2, so that contamination due to the adhesion of organic substances can be removed together with sterilization. .

As described above, the germicidal lamp according to the embodiment of the present invention irradiates ultraviolet rays to sterilize and decompose organic matter. However, if ultraviolet rays and other visible rays are irradiated, the germicidal lamp has an illumination function at night. It can also be made. An LED for illumination may be used instead of the LED that emits ultraviolet rays. The following effects can be obtained by emitting visible light from an LED for illumination at night using a capacitor or battery as a power source, for example: 1) It can be used as illumination during night traffic for vehicles and pedestrians 2) Groove covers such as gratings It can be used as a line of sight guidance when a vehicle or a pedestrian passes through a passage by attaching it to a road shoulder and flashing or continuously emitting light, and is particularly effective for warning of a road shoulder protruding or a sharp curve to the vehicle. ) By using LEDs of various colors such as red, blue, green, yellow, and white as LEDs, it is possible to bring about effects such as providing a function as illumination.
