Description

  The present invention relates to a toilet seat with a washstand using a sterilizing and purifying light source.

Conventionally, a large number of people sit on a toilet seat in a toilet, and it may become dirty with dirt, etc., or skin diseases may be transmitted.
In addition, even in hospital examination and treatment beds, many patients may come in contact with each other and pathogens may be transmitted.
Moreover, in a washstand or the like, a large amount of water that is not so dirty is lost in the drainage channel by hand washing, face washing, and the like.
For these sterilization and purification, photocatalysts such as titanium dioxide are coated on the surfaces of various objects and sterilized and purified by irradiating with natural light or artificial light. May cause damage to the eyes and eyes.

  The present invention is intended to solve the above problems.

  Toilet seat, water faucet, fountain direction change device attached to it, fountain direction change device, wash basin, sink, treatment bed, etc., or titanium dioxide, cadmium selenite・ Cadmium sulfide ・ Other photocatalysts are included or covered with a light source for sterilization and purification, such as an ultraviolet light source or short-wavelength visible light source that irradiates generated light. Ultrasonic, infrared, and other sensors that detect the presence of a human body detection sensor such as a TV camera, or a detector that detects that the toilet seat is separated from its lid, or its opening angle And an adjustment device that restricts the light irradiation to the upper surface of the toilet seat, and detects that the human body is in the light irradiation range and its vicinity, or detects that the toilet seat is separated from the lid If a human body is not present in the vicinity, such as detecting that no load is applied to the toilet seat, or the like, a light source for sterilization and purification that includes an electric circuit that cuts off the power supply to the light source is used. This can be solved by a sterilization and purification system.

By implementing the present invention, even if a large number of people sit on a toilet seat in a toilet, get dirty with dirt, or adhere to pathogenic bacteria such as skin diseases, the pollutants are decomposed and purified, and pathogens are also killed.
In addition, contamination by pathogens such as hospital examination and treatment beds can be prevented.
In addition, a large amount of water used in the wash basin of the washroom is sterilized and purified so that it can be used for toilet wash water and the like.
Since this does not cause any damage to humans, these can be performed using a powerful human thickness light source, and sterilization and purification are performed with high efficiency.

A person sits on a toilet seat 2 on which an elastic layer 4 and a plastic film cover 3 are hung, and uses it.
If the lever l is moved after the stool, the valve body 34 described later rises, and the water stored in the water tank 13 flows into the toilet 1 through the drain pipe 33.

Even in the winter, since there is the heat insulating tank 4, the low temperature of the toilet seat 2 without the heater is not transmitted, and it is not necessary to feel the coldness.
The plastic film cover 3 is clean and has a sterilized surface as will be described later.
If it is old, peel off the plastic film together with the adhesive layer 5 and replace it with a new one. (Since most of the substantial volume is a water-soluble material, it may be poured into a toilet bowl as with toilet paper and the like.)

The heat insulating wound 4 may be omitted, and the water-soluble plastic film cover 3 may be directly attached to the toilet seat.
When immersed in water, the water-soluble plastic layer on the back side melts, and the thin metal plating layer immediately falls apart.
The plastic film cover 3 is plated with silver, chrome, pure iron, copper, and other metals that are very thin and have some antibacterial action, so that the inner plastic will begin to dissolve soon after being immersed in water. You may give it.
Instead of the plastic film cover 3, a paper in which a short amount of glue that easily dissolves short fiber pulp in water is added to weakly bond the fibers may be used.

After the stool, when the lid 6 is placed on the plastic film cover 3, the limit switch 12 is activated, the light source 9 is energized and turned on, and a strong ultraviolet ray is generated. The ultraviolet ray passes through the plastic plate 8, and the plastic film The cover 3 is irradiated.
Although ultraviolet rays themselves have a bactericidal action, the photocatalytic action of titanium dioxide or the like present on the surface of the plastic film cover 3 causes water to be decomposed to generate hydroxy radicals, causing a chemical reaction, bactericidal action, Decomposition is performed strongly and purified. (At this time, generated hydroxy radicals and the like are blocked from reaching the underlying plastic film by the metal plating layer. If the plastic film is replaced in a short time, the plating layer may be omitted. In addition, in the case where only the sterilizing effect of ultraviolet rays is expected, the photocatalyst may be omitted.)

When the next person uses it, the lid 6 is raised to make it a backrest, so that the limit switch 12 is turned off, the light source 9 is turned off, and there is no danger to the human body.
In this way, the user can sit on a clean toilet seat each time.

In addition, a coating layer containing titanium dioxide may be provided on the surface of the toilet seat 2, and the plastic film cover 3 and the heat insulating layer 4 may be omitted.
When the toilet seat 2 is made of a transparent plastic and the surface is coated with a cadmium selenate, cadmium sulfide, or other paint containing a photocatalyst that can be purified even by visible light, the light source 9 uses a large number of visible light emitting diodes, etc. They can be attached to the lid 6 or embedded in the toilet seat.
You may attach the limit switch 12 to the lower surface of the toilet seat 2 which touches the toilet bowl 1. FIG.
Depending on the attachment position of the light source 9 on the lid 6, the shape of the light source, the use of a reflecting mirror, etc., the light may be applied to the toilet seat 2 in a horizontal state with the lid 6 standing.
In that case, instead of the limit switch 12, an ultrasonic wave or infrared ray is radiated forward, and a sensor for detecting the presence of a human is provided. When a human body is detected, the power supply to the light source is cut off. At other times, keep energizing.
An element that generates ultrasonic waves and infrared rays and an element that receives the ultrasonic waves and infrared rays are attached to the front surface of the lid 6, a human body sitting on the toilet seat is detected by reflection input of ultrasonic waves and infrared rays, the energization to the light source 9 is stopped, and the person If it leaves | separates, you may make it a solenoid valve work and water flows in a valve device, and it wash | cleans filth.
At this time, the exhaust fan in the toilet is started in conjunction with the electromagnetic valve, and after 1 to several minutes, it may be automatically stopped to remove the odor.
In conjunction with this fan, a disinfectant sprayer with an electric pump attached to the lid 6 may be operated to spray on the toilet seat so that sterilization can be performed more reliably.
Alternatively, the disinfectant may be sprayed when it is detected that a person approaches the toilet seat or when the opening / closing angle of the lid 6 and the toilet seat 2 changes.
To make cover 3 made of water-insoluble UV-resistant cloth (including non-woven fabric) or plastic film with or without photocatalyst so that it can be easily removed, washed and re-applied 2 The upper part of the same shape and the same area, the outer periphery and the edge of the central hole are provided with a hanging part that hangs about several centimeters downward. It can be sewn and formed into a slender bag with a top and bottom width of about 1cm, and a thin metal chain can be passed through the bag, or it can be sewn in advance and put on the toilet seat 2 easily and stably, and it can be easily removed and washed. It may be.
Instead of metal chains as belt-like (long type) weights, continuous wire ropes made of flexible metal wires such as copper, cords for electrical appliances, ceramics and concrete particles containing heavy metal balls, heavy metal oxides, etc. A belt-like weight enclosed between two pieces of cloth or plastic tape, a rubber cord / soft plastic belt kneaded with heavy metal powder, a cord / suzu-like object made of rubber or soft plastic, or a necklace using glass balls Objects and other weights may be sewn or sewn. (A thick and heavy cloth belt may be used.)
In addition to the toilet seat, such a cover can also be used as a treatment bed, a cloth cover, a pillow, a mattress, and other covers to be applied to the body of the treatment subject.
The belt-like weight may be sewn into four sides, three sides, or two sides as necessary.

A pressure-sensitive sensor such as piezoelectric rubber or a limit switch that closes the contact point when a large load is applied is attached to the lower surface of the toilet seat 2 with which the upper surface of the toilet bowl 1 comes into contact. May be cut off.
As a human presence / absence detection means, a TV camera is attached to the ceiling of the room (if necessary, a light source for camera operation is also provided), a computer that recognizes the pattern of the image is provided, and an image different from the memory pattern of the toilet seat in the memory The presence or absence of a human body may be detected by detecting by a camera or by detecting a human image, and energization may be turned on / off.
The sterilizing and purifying light source may also be attached to the ceiling, attached with a reflector or hood, the irradiation range is adjusted, and light is irradiated only on the toilet seat.
The ultraviolet light emitted from the germicidal light source is invisible to the eye, so that people can tell that it is coming out. A material layer may be attached.
A thin fluorescent material layer that hardly interferes with ultraviolet transmission may be attached to the entire inner surface.
The fluorescent substance may be formed with the letters “danger” and marks on the inner surface or the outer surface of the glass tube.

A belt-like blade with a front and rear width of about 1cm and a left and right width of about 20cm, consisting of a laterally running aluminum plate, stainless steel plate, metal-plated plastic plate, etc. When the lid 6 is directly covered on the toilet seat with a few mm intervals, the surface of each blade hangs down by its own weight, perpendicular to the toilet seat surface, and the lid 6 stands vertically. The blades are weighted so that the leading edge comes in contact with the stopper protrusion provided for each blade and stops properly, or a link mechanism that detects the relative angle between the toilet seat and the lid (or an electric control system may be used) And the inclination of the blade surface may be changed by the link mechanism in accordance with the angle formed by the two, so that the toilet seat surface is always irradiated with light from the light source.
When the link mechanism is used, appropriate irradiation of light can be performed even when the toilet seat is lifted and touches the lid when not in use.
For example, on the left edge of each blade, a notch of about 3mm square provided several millimeters ahead of the rotation axis of the blade. The upper end of the metal rod is connected to a spring that generates a pulling force connected to the upper end of the lid 6, and the lower end is the front number of a rotating shaft (not shown) that connects the toilet seat 2 and the lid 6. In cm, when connected to a rivet or the like provided at one point on the upper surface or side surface of the toilet seat via a metal rod or chain with a rotating shaft, if the opening angle of the toilet seat and lid is 90 degrees, the blade faces diagonally downward, If the opening / closing angle is 0 degree, the blade is perpendicular to the surface of the lid 6 or the like. The lower notches of the blades are located closer to the rotation axis of the blades, and the lower blades rotate more greatly with respect to changes in the opening / closing angle, so Even if the light of one sterilization purification light source provided changes the opening / closing angle, the entire toilet seat may be irradiated almost uniformly.
The light source for sterilization and purification is of one to several straight lines that run in the horizontal direction, and the bowl-shaped reflectors provided at the back of each light source rotate around the left and right axes in conjunction with the inclination of the lid 6, You may always make it go to the toilet seat surface.
On the outer or inner surface of the glass tube itself of this linear light source, a reflective surface made of metal plating with a slit in the front is provided, the light source itself is rotated around the long axis, and the opening angle of the toilet seat and lid is adjusted. You may make it rotate according to a change.
Even in these cases, the human body is prevented from being irradiated with light by a human body detection sensor or the like.
The light source may be attached below the front surface of the lid, and the blade or the like may face upward as the opening / closing angle of the lid and the toilet seat decreases.
A light source may also be attached above the front surface of the lid, and a blade or the like that faces downward as the opening / closing angle of the lid and the toilet seat decreases.
A strong linear light source may be attached near the upper edge of the lid 6, and the light source or the reflecting mirror may be rotated according to the opening / closing angle of the lid 6 and the toilet seat 2 so that the entire toilet seat is always irradiated with light. .
On the rear edge of the toilet seat 2, a linear light source with a reflector that always irradiates the entire toilet seat may be attached.
It is also possible to connect a single linear light source or four linear light sources around the toilet seat with a spring so that they are slightly floated, and if a person sits on the toilet seat, they may sink around the toilet seat.
The entire front surface of the lid 6 may be painted with an ultraviolet reflective paint or the like.
Even when the toilet seat 2 is stood and put on the lid, the light from these light sources does not easily reach the entire toilet seat unless a certain distance is left. Therefore, a short protrusion is formed forward from both sides near the lower end of the lid 6. A stopper that the toilet seat collides with is attached, and an elastic plate that extends several centimeters forward is attached to the outer surface of the stopper. A small hemispherical projection is provided on the inner surface of the front end, and the raised toilet seat touches the trailing edge of the projection. For example, a movable stopper that prevents the body from falling forward may be used.
In order to reduce power consumption, it may be possible to repeatedly energize the light source for 10 seconds and stop energizing for 50 seconds with a timer.
The light source may be replaced with a light emitting diode or the like.
In that case, several light emitting diodes are attached to several horizontally long light source mounting plates, and the blades and linear light sources are moved according to the opening / closing angles of the toilet seat 2 and the lid 6. You may make it change the direction of a board.

You may obtain what can be attached or detached to an existing toilet as follows.
The ridge 7, the transparent part 8, the rectangular light source 9, the bases 10 to 11, etc. are omitted, and a box with a transparent front side of about 20 × 20 × 4 cm in length × width × depth is pasted to the rear surface in advance. The release paper of the double-sided adhesive tape is peeled off and attached to the front surface of the lid 6 or fastened to the lid with screws provided at the four corners of the box.
A human body detection sensor that radiates infrared rays forward and receives the reflected light to detect the presence of the human body is provided at the center or the periphery of the box.
Within the box, about 1 to several sterilization light sources with a horizontal linear power cord having a lateral length of less than 20 cm and a diameter of about 2 cm are arranged in a grid.
On the front side of the box, several tens of blades made of aluminum plate, stainless steel plate, etc., which reflect UV rays with a width x depth of 20 x 1 cm and a thickness of about 0.5 mm are arranged in a grid.
A rotating shaft extending from the rear corners of the left and right edges of each blade to the left and right and entering the bearing hole on the side wall of the box is provided. A vertically long cloth tape connecting the left front edge of all blades is provided.
A spring connecting the upper blade and the upper wall of the box is provided, and all the blades are inclined toward the front lower 45 degrees.
A rivet (or screw) is attached to the left edge or upper surface of the toilet seat in front of a hinge (not shown) that connects the toilet seat 2 and the lid 6 (not shown), and the lower extended end of the cloth tape is connected thereto.
When the lid 6 is standing, the light from each light source passes between the blades, and most of the light is irradiated onto the toilet seat. However, when the lid is placed on the toilet seat, the tension of the cloth tape is loosened and the spring By force, all blades rotate 45 degrees, become perpendicular to the lid surface, and most of the light is irradiated onto the toilet seat. (Instead of cloth tape, the inclination of the blade may be changed by using a metal link mechanism as described above. Depending on the inclination of the lid, the blade itself changes its inclination by its own weight. However, when the toilet seat 2 is lifted up, there is a problem that the inclination of the blade does not change.)
If such a detachable boxed sterilization light source is used, it can be easily attached to the lid of an existing toilet.
A reflection surface opened only in front may be attached to the inner surface or outer surface of the glass tube of the linear light source, and the light source itself may be rotated.
This box is divided into a body with a light source that divides the front and back through a hinge and a lid with a blade attached, and the light source is replaced, or the position of the spring on the lid side is changed with a screw to change the direction of the blade. You may be able to do it.
A sensor that detects the presence of a person using infrared rays or ultrasonic waves is installed inside or outside this removable box, and when there is a person, the power supply circuit is opened and the light source in the box is energized. May be blocked.
Only one linear light source is housed in a box with a small vertical width to be attached to an existing lid, and the bowl-shaped reflector is rotated by the movement of the cloth tape or the like so that light is always irradiated onto the toilet seat. It may be.

A glass that is bonded to both glass plates by bordering the front surface of the lid 6 and two flat glass plates having substantially the same shape and the same area, with a thickness of about 0.1 to several mm, facing the opposite surfaces of the glass plates. A spacer made of etc. is held apart. (A spacer made up of a large number of dot-like projections may also be provided on the rear surface of the front glass plate.)
Low pressure argon gas, mercury vapor, etc. are sealed in the inner space obtained between the two glass plates, and electrodes in the form of planes, lattices, nets, etc. are provided on the front of the rear glass plate (even when plating on the glass surface) Good), the rear surface of the front glass plate is provided with a grid-like or net-like electrode made of metal wire, carbon fiber or the like to form a plate-like ultraviolet lamp, which is attached to the lid 6, and the lid 6 and the toilet seat 2 are Only when the electrodes are close to each other, the electrodes may be energized to generate ultraviolet rays.
Of course, you may provide the above blades which change an inclination according to the opening-and-closing angle of both in the front of this lamp | ramp.
Such a plate-like ultraviolet lamp can be used for various applications.
When a voltage is applied to the front electrode and the rear electrode, an inverter or the like is used like a normal UV lamp for the purpose of preventing energization from concentrating only in a specific narrow range. In the vertical grid, the rear electrodes are in the horizontal grid, and each is provided with a switching circuit. The electrodes to which voltage is applied are switched in sequence, as in a plasma TV screen, and only the intersection of the vertical and horizontal electrodes is energized. May be scanned to occur.
Two glass plates conforming to the shape of the upper surface of the toilet seat 2 are used to form a planar ultraviolet lamp, mounted on the toilet seat, and the surface of the upper glass plate is covered with a plastic plate that transmits ultraviolet rays to detect the human body. A sensor may be provided so that ultraviolet light is emitted except when a person is sitting, and the plastic surface with which the human body is in contact is always sterilized. (If a spacer composed of a large number of dot-like projections and linear projections is provided on the glass surface, the glass plate can be prevented from being broken even if the human weight is added.)
A small plate with a large number of light emitting diodes to irradiate the toilet seat is attached to the ceiling of the toilet, or the toilet seat 2 is made of transparent plastic, and a large number of light emitting diodes are embedded in it, and the surface is cadmium selenate.・ Cadmium sulfide ・ Other photocatalyst paints are applied, a human body detection sensor is provided, and light may be emitted from the light emitting diode toward the toilet seat surface except when a person is sitting. The human body detection sensor may be omitted and light may always be emitted. However, in the irradiation from the ceiling, if the toilet seat is lifted when not in use, the irradiation cannot be performed.

FIG. 3 is an enlarged plan view of a fountain direction changing nozzle adapter.
FIG. 4 is a longitudinal left side view thereof.
FIG. 5 is a cross-sectional view at the height of the upper surface of the knob 26.
22 is an elliptical fixing belt.
Reference numeral 23 denotes a bent pipe for connecting a faucet that is connected to a downward-facing nozzle of the faucet having a substantially key shape.
Reference numeral 24 is a valve having a shallow groove on the upper side that closes the front opening.
25 is a protruding line that runs laterally below the front surface and protrudes forward to the right.
26 is a fountain height adjustment knob in contact with the front surface.
Reference numeral 27 denotes a rotating shaft that penetrates the faucet connecting bending tube and the valve and continues to the knob. (This and the knob may be made of hard plastic, or the knob connected to the tube axis may be molded with a soft material and reinforced through a metal rod in the tube axis.)

Patent No. 2939507, Japanese Patent Application No. Sho 63-2705, “Water supply device for washing surface”, etc. have a straight pipe part with a faucet tip pointing downwards of several centimeters or more, so that the tubular connection part on the adapter side can be fitted. However, many of the faucets such as washstands in recent years have a short vertical tube of 2 cm or less on the lower surface of the front end of a long horizontal tube whose tip is closed.
In such a case, the adapter tube cannot be fitted and connected. Also, in general, the outer surface of the adapter tends to get dirty during long use.
The fountain direction changing nozzle adapter 17 solves these problems.
Each component of the adapter 17 is manufactured at low cost by injection molding a material such as soft vinyl chloride used for the hose using a set of molds.
A rotary shaft 27 connected to the knob 26 is passed through a hole below the valve 24, and the rear end of the shaft is fitted into the hole in the faucet connection bending tube 23.
The horizontal part at the lower end of the valve is fitted with an adhesive into the hole in the front of the curved tube.
The elliptical fixing belt 22 is molded in various sizes with the same mold, and an appropriate one is selected and attached to the bending tube, pushed in from the front, and fitted into the faucet. (Sold by holding several fixing belts in one pack of products.)
When the handle of the faucet 16 is turned, the water from the water pipe 15 passes through the nozzle of the faucet 16 and enters the bending pipe 23, flows from the rear to the front and upward, pushes the valve 24 forward according to the water pressure, and curves. Water spouts forward and upward from the gap formed at the front upper end of the pipe and valve.
When the water pressure is low, the degree of opening of the valve is small, the water flow is thin back and forth, and when the water pressure is high, the degree of openness is large, the water flow spreads back and forth, and as a result, the fountain keeps an almost constant height, Jumping out of the basin 14 is prevented.
When the height of the fountain is to be lowered, if the upper end of the height adjustment knob 26 is turned to the left, the knob comes into contact with a place where the height of the protruding line 25 is small, and the compression force on the valve 24 is weakened. 24 can be slightly tilted forward, the opening degree of the upper end becomes large, the water flow becomes thick in the front-rear direction, but the height of the fountain becomes low.
On the other hand, when the upper end of the knob is turned to the right, the pressure on the valve 24 is increased and the water flow becomes thinner, but the height of the fountain increases.

Further, when a person approaches the basin 14, a switch 19 with a human body detector is activated, and the short wavelength light source 20 that is normally lit and sterilizes and purifies the surface of the basin 14 and the fountain direction changing nozzle adapter. Shut off the power to the human body to prevent adverse effects on the human body.
In addition, several types of fixing belts 22 having different sizes are prepared, and an arbitrary number of annular plates having thicknesses of, for example, 1, 2, and 4 mm are stacked between the lower end of the faucet and the faucet connecting curved tube 23. It may be inserted to compensate for the deficiencies in the fixing belt.
For a fixed-size faucet, the fixing belt may be molded in a state of being attached to the tube 23.
In that case, you may close the opening part of the front of this belt with the film | membrane of the same material.

FIG. 6 is an enlarged vertical front view of the water tank 13 and the basin 14.
28 sinters a mixture of powder of activated carbon, silica / alumina / zeolite / other non-conductive material, and powder of conductive material such as carbon / metal, which is detachably attached to the bottom surface of the basin 14. Solid and porous conductive filter made of a material having equal conductivity.
29 is a conductive wire connected to it.
30 is the same conductive filter below.
31 is a conductive wire connected to it.
32 is an overflow hole provided with a water level sensor that closes the contact when the water surface comes into contact with the lower edge.
33 is a drain pipe provided on the bottom of the water tank 34 is a hemispherical valve element that closes the hole.

Large objects in the sewage that have flowed into the porous basin, such as by washing the face or washing hands, remain on the surface and eventually become emotional by the action of ultraviolet light or photocatalysis. (If it remains, a person removes it.)
The permeated contaminants in the water that pass through the conductive filters 28 and 30 are filtered and adsorbed, and very well purified water is stored below the water tank 13.
Assuming that a positive voltage of +/- 31 is applied to the conductive wire 29, active oxygen is generated in the filter 28, and active hydrogen is generated in the filter 28. In fact, the water pollutants passing through the filter are decomposed and sterilized, and the contaminants adhering to the filter are decomposed and purified.
Substances that have not been decomposed and purified by oxidation may be decomposed and purified by reduction, and by receiving both actions, a very strong water purification effect is produced.
In this case, the oxidation resistant substance in the pollutant stored in the filter 28 is difficult to be decomposed and purified and remains for a long time. However, if the energization direction is switched in a cycle of about 1 second to 10 minutes, the oxidation remaining in the filter 28 Substances that are resistant to water will also be purified.
However, if the switching direction of the energization direction is too short, the effect is reduced.
For example, if an alternating current of 50 Hz is applied, a very small amount of active oxygen is generated in the filter 28 for 1/100 second, and a small amount of substance in the vicinity of the particle surface constituting the filter is decomposed. In 1/100 second, active hydrogen that returns active oxygen to water is generated, and the amount of active oxygen or active hydrogen accumulated decreases.
Therefore, it is necessary to set a switching period of a certain long time, for example, a period of 1 second to 10 minutes. Therefore, a reversal power supply circuit including a multivibrator that performs reversal in such a cycle is used.
The optimum cycle varies depending on the flow rate per unit area, contaminant concentration, filter thickness, characteristics, particle size, pore size, applied voltage, and other factors. You may provide the optimal condition search apparatus etc. by the combination of the purification degree detection sensor and the computer for an automatic change of a period or a voltage.
Alternatively, the horizontal widths of the conductive filters 28 and 30 may be reduced to less than half, and the conductive filters 28 and 30 may be arranged on the left and right sides with a separation plate having a width of about 1.2 cm.
Alternatively, a conductive filter is further added under the conductive filter 230, and a voltage having the same polarity is applied to 28 and the additional filter, or another one is added under the filter and the same polarity as 30. Alternatively, the above voltage may be applied.
Such a conductive filter may be put in a stream and used for purifying the river, or for purifying gas containing moisture to some extent.
When provided in the stream, a photocatalyst particle layer may also be provided on the surface of the conductive filter, and the filter may be inclined so that sunlight may hit it and a purification action by the photocatalyst may be added.

When the lever l is moved, the valve body 34 is pulled up through a chain (not shown), water discharge to the toilet 1 begins, and when the water level in the aquarium begins to drop, the water level sensor provided at the lower edge of the overflow hole 32 works, and the faucet 16 The inside solenoid valve part is opened, and water from the water pipe 15 is ejected from the nozzle adapter 17 so that the hand can be raised and then washed.
In order to increase the amount of fountain, if the handle on the faucet 16 is moved, water that does not pass through the electromagnetic valve is also added, and a strong water flow is ejected from the nozzle.
When the valve body 34 eventually closes the drain pipe 33 again, the water level rises and the water level reaches the water level sensor at the lower edge of the overflow hole, the electrical circuit of the water level sensor is closed and the energization of the solenoid valve in the faucet 16 is cut off. The fountain stops.

When water is discharged by moving the handle of the faucet 16 for washing or the like in a water-filled state in which there is water up to the overflow hole in the water tank 13, the water flows into the tank (not shown) from the overflow hole and is accumulated.
Since the water is sterilized and purified, when the water level in the water tank 13 is lowered by moving the lever l, if there is water in the tank, the attached electric pump works and the water tank passes through the overflow hole. Returned to 13th.
At the same time, tap water passing through the tap 16 also flows into the aquarium, so that the aquarium reaches full water in a short time. (Normally, hand washing does not require the same amount of water as the whole tank.)
If the tank has a large capacity, the water can be used for garden watering and other purposes.
The water stored in the tank may not be returned to the water tank 13 but may be used only for other purposes.

43 is a frame for adjusting the opening angle of the support bar fitted around the support bar fixed body.

Hold the spray gun 35, the support rod fixed body 38, etc. in the hand, point the openings of the pyramid-shaped shielding cover 41 and the replacement shielding cover 42 toward the toilet seat 2, the washbasin 15, and other parts to be painted, and press the push button 36. Then, the paint is sprayed into the cover 42 from the nozzle 37 of the spray gun 35.
Since the paint hardly goes out from the inside of the cover 42, the additional application of the photocatalyst paint can be easily performed by anyone without contaminating the surroundings.
If the inner surface of the replacement shielding cover 42 is soiled with paint and it becomes difficult to see the spraying range of the paint, the cover may be removed from the curved portion 40 and replaced.
The paint spraying range can be adjusted by moving the support rod opening angle adjusting frame 43 back and forth.
This apparatus can be used for painting indoor walls, ceilings, and other photocatalysts, and can also be used for painting general paints.

In addition, the support bar fixed body 38 is made of a hard material, a hole having a diameter of about several centimeters is formed in the center, the front end of each support bar is warped on the outer edge via a rotation shaft, and a handle that is easy to hold is provided on the lower edge. The nozzle of the mounting and spray gun may be directed in any direction within the central hole. (The center hole may be a partial spherical surface, and a spherical body having a small hole through which the nozzle of the spray gun passes may be fitted.)
You may provide the spring made from a steel wire which gives the force which each support bar opens mutually.
Even if the rubber belt is sewed on the rear edge of the shielding cover 41 and the opening / closing angle of the support bar is reduced to some extent, the plastic film may be prevented from sagging.
An air tube for reducing the gap between the annular cover and the object to be painted may be attached to the rear edge of the shielding cover 41.
The support rod fixing body 38 can be of any structure, but a spray gun holder may be attached to it. The number of support rods 39 can be increased or decreased, a rotation shaft can be inserted between the support rods, and the support rod can be bent. Insert a coil spring in the middle of each support rod to give stretchability, make each support rod a tube made of rubber or soft plastic with a diameter of 1 to several centimeters, and draw in and out with a hand pump etc. When not in use It may be made small and foldable.
In the case of painting the outer wall of a building, it is only necessary to scan the painted surface by moving the electric spray nozzle with a system using a large air injection type support rod that works with a power pump.
Each support rod is made of a hard tube, and a bellows tube connected to an exhaust centrifugal pump is connected to the front end of the tube or a small hole formed in the covers 41 and 42, and the air in the cover is exhausted, and the air pressure in the cover is reduced. It may be made slightly lower than the outside so that the cover is brought into close contact with the object to be painted and at the same time the paint does not come out.
In this case, replace the spray gun with an electric drill, wire brush, rock drill, or other equipment that generates dust, and use it to remove the asbestos layer and other substances that are worn on the wall and are harmful to the human body. Also good.
A turbine may be attached to the drill or the wire brush, and the air in the cover may be sucked with an exhaust pump to generate the rotational power of the device. (In order to prevent the pressure inside the cover from falling below a certain level and the cover from collapsing, a hole is made in a part of the cover, and a valve that opens when the internal pressure falls below a certain value is attached.)
The support rod may be formed by winding a steel wire in a coil shape having a pyramid shape or a conical shape, a shield cover made of a transparent plastic film having a cone shape is attached to the periphery thereof, and a replacement cover may be attached to the inner surface. (Put them in front and back between two fixed bars connected by hinges, and store them in a reduced volume.)
Instead of the pyramidal and conical steel wires, a tube that can be hardened or softened by taking air into and out of the inside may be used.
