Description

  The present invention relates to a dust box used in, for example, a toilet, and in particular, uses the photocatalytic action of titanium oxide to decompose used paper such as toilet paper, tissue paper, absorbent cotton, and non-woven fabric to which filth has adhered. The present invention relates to an apparatus that can perform sterilization and disinfection efficiently.

  Conventionally, garbage cans are used in toilets. One of them is a container with a lid, in which a bucket is contained, and used paper discarded in this is taken out and discarded. In Southeast Asia, it is customary to dispose of toilet paper used in toilets in a trash bin and dispose of it as waste without washing it with filth after use. It has been pointed out that this waste bin is not preferable because it causes the propagation of pathogenic bacteria in terms of hygiene.

  On the other hand, a method and apparatus for treating filth containing fungi have already been proposed. Explaining its configuration, the processing vessel main body is provided with a filth distribution inlet and a filth discharge port fitted with an automatic valve that automatically opens and closes after a certain period of time. A rotary stirrer with attached blades is attached.

In addition, an ultraviolet germicidal lamp is attached to the inside upper part of the processing container, and granular titanium dioxide of 5 mm to 1 cm is housed in a storage bag in the center of the inside and is locked to the inner wall of the processing container. (For example, refer to Patent Document 1). In the conventional method and apparatus for treating waste containing fungi, the waste flowing into the treatment container is sterilized by the photocatalytic action of titanium dioxide that receives ultraviolet rays for a certain period of time in the treatment container, and then automatically opened. It is discharged to the outside by an automatic valve.
JP-A-7-275338

  The conventional configuration has the following problems. First, in the processing method and apparatus for filth containing fungi, the object to be treated is limited to filth. And although the filth is stirred and unraveled by the stirring blade, titanium dioxide is stored in the storage bag, so it cannot receive enough light from the ultraviolet germicidal lamp, and the contact area with the filth is also very high. It will be less, and sufficient deodorizing and sterilizing effects will not be obtained.

  Furthermore, large filth remaining without being sufficiently decomposed is also discharged to the outside by an automatic valve that automatically opens, which is problematic from the viewpoint of environmental problems. Therefore, the technical means of the method and apparatus for treating filth containing fungi cannot be diverted immediately to a trash box used in a toilet or the like.

  The present invention has been made based on such points, and its purpose is to use the photocatalytic action of titanium oxide so that, for example, the used paper can be efficiently decomposed and sterilized in a toilet. It is to provide a trash can that can be hygienically managed.

  In order to achieve the above object, a trash can according to claim 1 of the present invention comprises a container main body coated with titanium oxide on the inner wall surface and capable of containing water therein, the upper opening of the container main body being openable and closable, and an ultraviolet ray inside. A lid provided with a lamp, a mesh body placed in the container body and coated with titanium oxide on its surface, and a circulation in which used papers put into the mesh body are stirred and decomposed in water And a pump.

  The trash bin according to claim 2 is the trash bin according to claim 1, wherein the circulation pump opens a hole in the discharge pipe so as to discharge water slightly inward from the tangential direction to the net body, and In addition, a baffle plate that is curvedly formed along the net rod body is disposed in front of the net rod body in the water discharge direction.

  A trash can according to claim 3 comprises: a container body that is coated with titanium oxide on the inner wall surface and that can store water therein; an upper opening portion of the container body that can be opened and closed; A mesh body placed in the container body and coated with titanium oxide on the surface, and a stirring blade for stirring and decomposing used paper or filth put in the mesh body with water. It is characterized by that.

  According to a fourth aspect of the present invention, in the trash can according to the first to third aspects, the inner wall surface of the container body is formed in a corrugated shape.

  The trash box of the present invention is designed to contain water in the container body, and titanium oxide is applied to the inner wall surface and the net housing of the container body, and the titanium oxide is irradiated with ultraviolet rays from an ultraviolet lamp. Is done. Used paper is forcibly decomposed in the container main body with a stirring blade or a circulation pump, and is efficiently brought into contact with titanium oxide applied to the inner wall surface or the surface of the mesh casing. And it is sterilized by the photocatalytic action. The ultraviolet lamp in the container body is interlocked with the opening / closing operation of the lid, and is turned off when opened and turned on only when closed, so that ultraviolet rays are not irradiated to the eyes of the operator. The decomposition product of the used paper is flowed into the sewer in a sterilized state. Further, what remains in the mesh body without being dissolved in water is discarded by lifting the mesh body from the container body.

  According to the recycle bin of the present invention, the used papers put into the container main body are decomposed by a water flow or a stirring water flow circulating in the water, and this decomposition product is applied to the inner wall surface or the net frame of the container main body. It comes into contact with titanium oxide and is sterilized by the photocatalytic action of ultraviolet rays from an ultraviolet lamp. Moreover, the decomposition product can be disposed of in a sewer along with water. Therefore, used toilet paper and filth can be managed hygienically.

  Further, when the inner wall surface of the container body is formed in a corrugated shape, the sterilizing effect is further promoted. Moreover, since the ultraviolet lamp in the container body is turned on only when the lid is closed in conjunction with the opening / closing operation of the lid, the eyes can be protected without being irradiated with the ultraviolet rays. Moreover, what remains in the mesh body without being dissolved in water can be discarded by lifting the mesh body from the container body.

  The first embodiment of the present invention will be described below with reference to FIGS. FIG. 1 is a perspective view of a trash box 100 of the present invention, FIG. 2 is a cross-sectional view showing the internal configuration and electric wiring of the trash box, and FIGS. 3 and 4 are electric circuit diagrams. First, there is a container body 1, and a lid 5 is provided on the upper part. The container body 1 is made of stainless steel or synthetic resin having high corrosion resistance, and has a cylindrical shape with a capacity of 150 to 300 liters. Titanium oxide LC that exhibits a photocatalytic action is applied to the inner wall surface 1A of the container body 1 by spray coating or baking coating.

  The inner wall surface 1A of the container body 1 is formed in a corrugated cross section, and titanium oxide LC is widely applied to this surface. As a result, the surface area of the inner wall surface 1A is increased, and the decomposition, sterilization and sterilization action of the used paper P and the like by the titanium oxide LC is further enhanced. Of course, the corrugated shape may be formed in the longitudinal direction of the inner wall surface 1A. Moreover, the photocatalytic action by the titanium oxide LC can be sufficiently exhibited even if it is merely a flat surface.

  A lid 5 that can be opened and closed by a hinge 3 is pivotally attached to the upper opening of the container body 1, and an ultraviolet lamp L is provided on the inner wall of the lid 5. A switch means (for example, a limit switch or a proximity switch) S1 for sensing the opening edge 5A of the lid 5 is provided on the upper edge of the opening of the container body 1. The switch means S1 turns on the ultraviolet lamp L when the lid 5 is closed, and turns off the ultraviolet lamp L when the lid 5 is opened. On the floor plate 1B in the container main body 1, for example, a stainless steel mesh casing 7 on which titanium oxide LC is applied by spraying or baking is placed on the surface in a freely removable manner. The floor board 1B is, for example, a stainless steel mesh board, and the titanium oxide LC is also applied to the surface of the floor board 1B by spray coating or baking coating. Of course, whether or not to apply the titanium oxide LC to the floor board 1B is arbitrarily selected. The roughness (mesh) of the mesh between the mesh casing 7 and the floor board 1B is set in a range of # 10 to # 15 so that the decomposed product W1 of the used paper P can be passed.

  Water W is formed inside the container main body 1 so as to be accommodated, and water is supplied manually by a bucket or a water hose. The amount of water W overflowed from the overflow port 9A provided in the upper part of the container is drained into the sewer through the drain pipe 9B. The overflow port 9A may not be provided. A bottom plate 1F is disposed at the bottom of the container body 1, and a circulation pump PO is installed in the upper water. The circulation pump PO is, for example, a submersible pump, and a motor unit is hermetically housed in a case. A discharge pipe P1 and a suction pipe P2 are connected to the circulation pump PO. The discharge pipe P1 passes through the floor plate 1B and is connected to a high position in the container body 1. Thereby, the decomposition product W1 which precipitates is prevented from being sucked. The suction pipe P2 is also piped up to a high position in the container body 1 through the floor board 1B. Thus, a water flow that circulates in the container body 1 is formed, and the used paper P that has been thrown into the mesh body 7 is decomposed by being circulated together with the water W in the container body 1.

  In the present embodiment, as shown in FIG. 3, the circulation pump PO opens one or more holes in the discharge pipe P1 and discharges water to the net housing 7 slightly inward from the tangential direction. In addition, a baffle plate 8 curved along the mesh casing 7 was disposed in front of the mesh casing 7 in the water discharge direction. As a result, a vortex is formed in the net body 7 to more efficiently decompose the used paper P introduced into the net body 7. Therefore, not only toilet paper that is easy to melt, but also tissue paper that has a long fiber length and is difficult to melt can be actively decomposed. Of course, the trash box of the present invention is not limited to the configuration of the circulation pump PO, and a hole provided in the discharge pipe P1 may be arranged along the wall surface of the container body 1 to form a vortex. The discharge pipe P1 of the circulation pump PO may be arranged in an arbitrary direction so that an appropriate water flow is formed in the container body 1.

  The circulation pump PO is driven by turning on the power “on operation” and stopped by turning off the power “off operation”. That is, ON / OFF control is performed by turning the power supply on and off manually. Normally, the power is turned on during daytime when the frequency of use is high, and the power is turned off at night. Moreover, the drain valve V2 is arrange | positioned at the bottom plate 1F of the said container main body 1, and the sediment which accumulates on a bottom regularly is discharged | emitted to a sewer. Of course, this drain valve V2 may be omitted. In this case, the container main body 1 is tilted by hand to discharge water and the treated decomposed product W1 into a sewer or the like.

  Next, the electric circuit of the trash can 100 will be described with reference to FIGS. As shown in FIG. 2, the power source is a 100-volt commercial power source, and this power source is connected to the outlet 11 via a power switch SO. The power switch SO, the switch means S1, and the ultraviolet lamp L are connected in series. Thereby, when the cover 5 is opened with the power switch SO turned on, the switch means S1 is turned off and the ultraviolet lamp L is turned off. When the cover 5 is closed, the switch means S1 is turned on and the ultraviolet lamp L is turned on. . Further, the circulation pump PO is directly connected to the power switch SO. When the power switch SO is in an on state, the circulation pump PO is always in an operation state regardless of the on / off operation of the switch means S1.

  Of course, as shown in FIG. 5, the circulating pump PO is connected to the switch means S1 in series so as to stop the operation when the lid 5 is opened and to operate only when the lid is closed, as with the ultraviolet lamp L. May be. Thereby, the ultraviolet lamp L and the circulation pump PO are manually operated so that they are always connected to the power source during the daytime by turning on / off the switch means S1 and are shut off by turning off the power switch SO at nighttime. If the on / off operation of the ultraviolet lamp L can be ignored by the switch means S1 interlocked with the opening / closing of the lid 5, the switch means S1 is omitted, and only the power switch SO is used to connect the ultraviolet lamp L and the above-described operation. The circulation pump PO may be turned on / off.

  The operation will be described based on the above configuration. In the recycle bin 100, titanium oxide LC is applied to the inner wall surface 1A, the net housing 7, the floor board 1B, etc. of the container body 1, and in the daytime, photocatalysis is achieved by irradiating ultraviolet light from the ultraviolet lamp L when the lid 5 is closed. Demonstrated. As a result, the used paper P such as toilet paper, tissue paper, absorbent cotton, non-woven fabric, etc. to which dirt is attached is forcibly decomposed in the container main body 1 by the vortex flow of the circulation pump PO, and the inner wall inner wall surface 1A and the net frame 7 is forcibly brought into contact with titanium oxide LC applied to the surface of 7. And since the photocatalytic action of titanium oxide LC works also in the fluid, the decomposition product W1 (including the waste O) of the used paper P is sterilized by the photocatalytic action. At the same time, a deodorizing effect and a sterilizing effect are exhibited. The ultraviolet lamp L in the container body 1 is interlocked with the opening / closing operation of the lid 5 and is turned off when opened and turned on only when the mouth is closed, so that ultraviolet rays are not irradiated to the eyes of the operator.

  When titanium oxide LC is baked and coated on the inner wall surface 1A and the mesh body 7 of the container body 1 and further on the surface of the floor board 1B, the titanium oxide LC becomes difficult to peel off and the photocatalytic action is maintained for a long period of time. Moreover, since the inner wall surface 1A of the container main body 1 is formed in a corrugated shape, the contact surface area is enlarged as compared with the case of a flat surface, and the sterilizing effect is more efficiently exhibited. At night, when the toilet is used less frequently, the power switch SO is turned off or the outlet 11 is disconnected to stop the irradiation of ultraviolet rays and the stirring of the fluid.

  Further, by setting the mesh roughness of the mesh frame 7 and the floor board 1B within the range of # 10 to # 15, there is no clogging phenomenon of the decomposed product W1 in which the used paper P is dissolved in the water W. It is easy to efficiently circulate the fluid through the mesh body 7 and the mesh of the floor board 1B. The sterilized decomposition product can be discarded by flowing into a sewer. In addition, what remains in the mesh body 7 without being dissolved in the water W is pulled out of the container body 1 and discarded separately. Further, the sediment that regularly accumulates at the bottom of the container body 1 is discharged from the drain valve V2 to the sewer or the like, or the container body 1 is lifted and tilted and discharged from the upper opening to the sewer.

  As described above, according to the embodiment of the present invention, the following effects can be obtained. First, since the titanium oxide LC is applied to the inner wall surface 1A, the net housing 7 and the floor board 1B of the container body 1 and irradiated with the ultraviolet lamp L, the used paper P (including the waste O) is decomposed by eddy current. Thus, the photocatalytic action can be exerted by forcibly contacting the inner wall surface 1A of the container main body 1 or the net housing 7, and the used paper P (including the waste O) can be sterilized efficiently. And these processed decomposition products W1 can be discarded to a sewer, etc., and can be managed hygienically.

  Moreover, when the inner wall surface 1A of the container body 1 is formed in a corrugated shape, the surface area is increased and the sterilizing function is further promoted. Further, when the ultraviolet lamp L in the container body 1 is lit only when the lid is closed in conjunction with the opening / closing operation of the lid, the ultraviolet rays are not irradiated to the eyes of the operator, and safety can be ensured. Further, what remains in the mesh body 7 without being dissolved in the water W can be discarded by lifting the mesh body 7 from the container body 1.

  When the titanium oxide LC exhibiting photocatalytic action is baked and applied to the inner wall surface 1A of the container body 1, and the titanium oxide LC having photocatalytic action is baked and applied to the surface of the mesh body 7 and the floor board 1B, The titanium oxide LC does not peel off, and the bactericidal effect can be maintained over a long period.

  Next, a second embodiment of the present invention will be described with reference to FIGS. The trash can 200 employs a stirring blade 10 in place of the circulation pump PO employed in the trash can 100 in the first embodiment. The configuration is such that a motor M is disposed on the back side of the bottom plate 1F of the container body 1, and a stirring blade 10 is provided in a space with the floor plate 1B. Since other configurations are the same as those of the first embodiment, the same reference numerals are given and description thereof is omitted. Further, as shown in FIGS. 7 and 8, the electrical circuit diagram has the same configuration as that of the first embodiment, except that the circulation pump PO is changed to the stirring blade 10 and the motor M. is there.

  According to the recycle bin 200 of the second embodiment, the water W in the container body 1 is circulated by the rotation of the stirring blade 10 and the used paper P (including the waste O) is stirred and decomposed by the vortex. Then, it is forced to come into contact with the titanium oxide LC applied to the inner wall surface 1A or the surface of the mesh body 7. Thereby, since the photocatalytic action of titanium oxide works even in the fluid, the used paper P (including the waste O) is sterilized. Other operations are the same as those in the first embodiment, and a description thereof is omitted here.

  The present invention is not limited to the first embodiment. For example, as shown in FIGS. 9 and 10, the design can be changed as in the trash cans 300 and 400 of the third and fourth embodiments. The trash bins 300 and 400 are provided with a supply valve V1 for supplying water W to the outside of the container body 1 and a supply port 9 and a float switch (not shown) at the upper part of the container body 1 in order to automatically supply water W. These are connected to a control unit CO connected to a power source for automatic control. Further, the drain valve V2 provided on the bottom plate 1B of the container body 1 is connected to the control unit CO for automatic drainage.

  As another modification, a timer T that is set to be turned off in the morning, for example, 12 hours later, and used in an on state can be connected to the control unit CO. Also, in the morning, for example, at 7 o'clock, set to turn off at 7 o'clock after 12 hours, maintain the off state at night, and repeat the operation every day to turn on again at around 7 o'clock the next morning It is also possible to connect a program timer PT that is continuously operated automatically. Thereby, the operation / stop of the ultraviolet lamp L, the circulation pump PO, or the motor M of the stirring blade 10 can be controlled in time (operated in the daytime and stopped at the nighttime).

  According to the trash bins 300 and 400 of the third and fourth embodiments, automatic water supply into the container body 1, automatic operation based on time management of the ultraviolet lamp L, the circulation pump PO, or the stirring blade 10, and the processed It is possible to automatically discharge the decomposition product W1. The operation cycle is also automatically repeated every day.

  Although the trash box of the present invention has been shown for a toilet, the present invention is not limited to this and can be applied to various uses. For example, the present invention can also be applied to used paper waste bins installed in other places in the home such as hygiene management in hospitals and kitchens.
