Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention relates to an automatic urinal cleaning device for men.
More specifically, it is used by attaching it to the flush valve part of a men's urinal, detecting a person with a built-in sensor that detects by radiation, and when the person adds and goes away, it automatically presses the flash valve to prevent it. The present invention relates to an automatic urinal cleaning device for men that flushes water containing a deodorant cleaning agent.

[Prior Art] As a conventional men's urinal cleaning device, a push button type flush valve is provided on the top of the men's urinal, one end of which is connected to the tap water pipe of the water pressure source, and the other end is opened to the urinal. Devices are commonly used. In this cleaning device, when a person wears or puts on, the person pushes a push button to open the flush valve to open the normally closed valve to flush water. However, with this cleaning method, there are individual differences in the time of pressing and the time of flowing water varies, and some people forget to press the push button, so it becomes dirty unless you wash and clean the urinal every day after all. , Odor will remain.

In order to eliminate such drawbacks and save labor, an automatic cleaning device having an automatic push button type flash valve with an infrared sensor attached to the upper part of the men's urinal is recently used. With this cleaning device, when a person stands in front of the toilet bowl to add a dose, infrared rays from the human body are detected, and when the person adds a dose and leaves, the push button of the flash valve is automatically pressed for a short time to close the normally closed valve. Wash with open water.

[Problems to be Solved by the Invention] However, in the above-described conventional cleaning device, water flows only for a short time after a person has used it. Since urine contains various components, it is difficult to completely wash away urine attached to the wall of the toilet bowl with water alone. If a small amount is left unwashed, the number of times the toilet bowl is used becomes more noticeable, and the dirt becomes more noticeable, and along with this, the odor peculiar to urine remains, causing discomfort. As a method of solving such a problem, it may be possible to make a dedicated cleaning liquid instead of tap water and to flow it instead of water, but this requires an equipment cost and a large amount of chemicals, which is not economical.

The purpose of the present invention is to improve the shortcomings of the conventional automatic cleaning device for men's urinals. It is a simple device that can be easily attached to men's urinals, and it is excellent in cleaning and deodorizing urinals and also exhibits aroma effects. An object of the present invention is to provide an automatic cleaning device for men's urinals that can reduce the use of medicines.

First flows into the toilet bowl and the tank is filled with water, then the water containing the drug A men's urinal automatic flushing device is provided which is characterized as being drained into a toilet bowl.

[Operation] The automatic cleaning device of the present invention is used by being installed between the tap water pipe of the water pressure source and the tap water pipe opening at the upper part of the men's urinal.

The device of the present invention is provided with a normally closed valve for tap water, a tank having a normally open valve for accommodating an antifouling deodorant cleaning agent communicating with the lower part thereof, and radiating the approaching state and leaving state of a person. It is characterized by having a sensor that detects a line and a control mechanism that operates to open the normally closed valve by a combination of a person approach signal and a departure signal from the sensor.

The infrared sensor part oscillates an infrared pulse, receives the reflected wave, and outputs an exit signal of the person when the reflected wave is stopped and a mechanism for controlling the drive of the drive motor by the exit signal of the person. have. When a person leaves, a drive motor is driven within a required time by a combination of a person approach signal and a person leaving signal, a gear is driven, a cam is operated, and a normally-closed valve is operated by a push lever at the tip of the cam. The normally closed valve can be opened by pressing a push button.

The control mechanism is set so that the normally closed valve is opened in advance and the interval between running water is suitable for cleaning.

When the normally closed valve is opened 1) Tap water passing through the normally closed valve is flushed to the urinal.

2) In addition, part of the tap water flows into the tank containing the antifouling / deodorant cleaning agent (solid) that communicates with the bottom of the normally closed valve through the normally open valve provided in the tank. As the water level in the tank rises, the float of the normally open valve top with float rises, and when the water fills to a predetermined level, the normally open valve is closed by the float top and the flow of water into the tank stops.
During this period, the solid antifouling deodorant detergent gradually dissolves in water from its surface.

Thus, first, the urinal is washed with water.

When the normally closed valve closes automatically, 1) the flow of tap water stops.

2) And the normally open valve of the tank opens, and the water in the tank in which the antifouling / deodorant cleaning agent is slightly dissolved flushes to the urinal.

Thus, after washing with water containing the antifouling deodorant detergent, the washing is continued.

Since washing is performed after washing with water, the amount of chemicals used is small and effective washing is possible. The medicine can have not only cleaning and deodorizing effects, but also fragrance effects that give a refreshing feeling to people.

Unlike the conventional device, the automatic cleaning device of the present invention is not only simply rinsed with water but also rinsed with water containing an antifouling deodorant cleaning agent, so that the amount of chemicals used is small and effective. It can be used for antifouling and deodorant cleaning, and the toilet bowl can always be kept clean and clean.

The normally closed valve 6 includes a water supply port 7, a water amount control valve 8, which is connected to a tap water pipe of a water pressure source in addition to the valve portion to receive water.
The normally closed valve 6 has a push button 9 for pressing and opening the valve portion, a drain port 10, and the like. A socket 11 for connecting to a tap water pipe opening to the upper part of the toilet is provided in the lower part of the drainage port 10, and a threaded hole 12 is provided in the side surface of the socket 11. The side tube 13 has one end projecting deeply into the socket 11 through the hole 12, and the upper tube wall of the projecting tube end is notched and opened.

The other end of the side pipe 13 is open-connected to the valve chamber 15 of the normally open valve 14. A tank 16 for containing an antifouling / deodorant cleaning agent is provided above the normally open valve 14. Valve chamber 15 of normally open valve 14
A water passage 17 is provided above the center of the upper part and opens into the tank 16. In addition, a water passage hole 18 is provided at an upper portion of the water passage 17 from the water passage 17 in the outer peripheral direction to communicate with the inside of the tank 16. The upper surface of the valve chamber 15 forms a valve seat, and the top 19 of the valve chamber serves as a valve body. The lower end of a float rod 20 that can move up and down the water passage 17 is connected to the top 19, and the upper end of the float 21 is inside the tank 16. Is combined with.

FIG. 4 is a side sectional view for explaining the inflow / outflow of water into / from the tank 16 containing the antifouling / deodorant cleaning agent while the normally closed valve 6 is opened / closed.

As shown in FIG. 4, when the normally closed valve 6 is closed, there is no running water from the normally closed valve 6 and the state is as shown in FIG. 4-1, but when the normally closed valve is opened, the flow of tap water is Most of them flow through the socket 11 toward the urinal, and some of them flow from the side pipe 13 to the normally open valve 1.
4 and flows into the tank 16 (FIG. 4-2). When water flows into the tank and the water surface rises to reach the float 21, the float 21 rises due to buoyancy along with the rise of the water surface, and the top 19 also rises accordingly. When the top 19 rises due to the rise of the water surface and comes into close contact with the upper surface of the valve chamber 15, the inflow of water into the tank is stopped, the inside of the tank 16 is filled with a predetermined amount of water, and the water is retained as it is. Then, the water flowing out of the normally closed valve 6 flows to the urinal (Fig. 4-3).

This state is maintained while the normally closed valve 6 is opened,
When the normally closed valve 6 is closed at the end of the flowing water time, the water pressure pushing up the top 19 of the normally open valve 14 disappears, the top 19 is lowered and the normally open valve 14 is opened, and the water in the tank 16 flows out and becomes small. It flows to the toilet bowl (Fig. 4-4).

Since the solid antifouling / deodorant cleaning agent 22 is contained in the tank 16 and dissolves in the water in the tank 16, the water flowing out from the tank 16 acts as an antifouling / deodorant cleaning liquid.

The tank 16 is made taller than the height of the float when it is filled with a predetermined amount of water. About 100 to 500 ml is usually selected as the amount of water to fill the tank 16.

A solid antifouling / deodorant cleaning agent 22 is stored in the tank 16. The antifouling / deodorant cleaning agent 22 is water-soluble and is constructed so as to gradually dissolve from its surface when immersed in water. The antifouling / deodorant cleaning agent 22 is mainly mixed with a chemical so that it can act as a detergent and a deodorant, but it can be mixed with an aromatic agent, a fragrance or the like to give a refreshing feeling to a person. . Although the upper portion of the tank 16 is closed, it may be opened or may be provided with an openable lid.
The tank 16 is made of plastic. It is made of metal, glass, ceramics, etc., but usually made of transparent plastic.

FIG. 5 is a block system diagram showing an outline of an operation system of the automatic cleaning device of the present invention. In FIGS. 1 to 3 and 5, reference numeral 25 denotes a DC power source, which is usually a dry battery. For example, four single to AA dry cells are used. The power supply voltage is DC 6V. These are set to be exchangeable. A storage battery can be used instead of the dry battery. Since the device of the present invention consumes less electricity, a dry battery power source is sufficient for long-term practical use. This is also an advantage that the device of the present invention can be easily used without requiring wiring work for an AC power supply. However, it is of course possible to use an AC power source instead of the battery.

The motor 26 is driven by the output of the battery 25. The rotation of the motor 26 is transmitted to the cam 28 by the drive transmission mechanism (gear portion) 27, and the push lever 2 at the tip of the cam 28 is pushed.
The normally closed valve 6 can be opened by operating the valve 9 and pressing the push button 9 of the normally closed valve 6.

The infrared sensor unit 30 includes infrared diodes 31 and 32 that emit infrared pulses, a phototransistor (light receiving element) 33 that receives a reflected wave thereof, an infrared detection circuit that detects and amplifies infrared rays, and controls infrared pulse transmission, and a motor. The infrared detection control mechanism 34 having the control mechanism of is incorporated. In front of the front of the infrared sensor unit 30,
There is a window portion 5, and the window portion 5 is provided side by side with light emitting windows 31a and 32a of infrared light emitting diodes and a light receiving window 33a of a light receiving element. Reference numeral 35 is an LED that indicates when the battery is replaced.

In the above figures, the shape of the cover case 1 is oval when viewed from the front, but it may be rectangular, semicircular, or any other shape.

Further, the arrangement of the tank 16, the infrared sensor unit 30, the battery 25, the motor 26, the drive transmission mechanism 27, and other constituent parts in the apparatus main body in the cover case 1 can be changed appropriately.

Further, the light emitting windows 31a and 32a of the infrared light emitting diodes, the light receiving windows 33a of the light receiving elements, which are arranged slightly to the right of the center of the front surface,
The position of the LED 35 or the like can be changed to the center or slightly to the left of the center. It is also possible to change the position of each other.

These shapes and arrangements are functionally and rationally selected in relation to the design.

Next, the operation of the device of the present invention will be described.

The infrared light emitting diodes 31 and 32 emit infrared pulses at a rate of once per second, for example, and the light receiving element 33 receives a reflected wave from this human body, and detects whether or not a person has left depending on the presence or absence of this reflected wave. .

After the reflected wave is continuously detected for about 8 seconds or more, when the reflected wave is not detected even once, a leaving signal is generated as if the person added a small amount of diversion and left, and the infrared detection control mechanism 34 The motor 26 is rotated by the output of the battery 25 by the control mechanism. The rotation of the motor 26 activates the drive transmission mechanism (gear portion) 27 to activate the cam 28, and the push lever 29 pushes the normally closed valve push button 9 to open the normally closed valve 6.
Tap water flows downward through the normally closed valve 6. The time from when a person leaves to the flow of tap water is within about 2 seconds.
The time for which the normally closed valve 6 is opened and tap water is supplied is set in advance by the infrared detection control mechanism 34 of the infrared sensor unit 30. When the set predetermined time has passed, the output of the battery 25 to the motor 26 is stopped by the infrared detection control mechanism 34, the cam 28 returns, and the normally closed valve 6 is closed. The situation from the opening of the normally closed valve 6 to the closing of the normally closed valve 6 until the water containing the antifouling / deodorant cleaning agent in the tank 16 flows is as described above.

Immediately after the person puts up the toilet in front of the toilet, the device of the present invention operates automatically, first flushes the toilet with flushing tap water and then rinses with tap water followed by a decontamination deodorant cleaner The water (in the tank) is flushed and the toilet bowl is cleaned.

By flowing the water containing the chemicals after the washing with water, the cleaning can be performed well without leaving stains or odors with the use of a small amount of the chemicals. Since the drug is prepared so as to be gradually and moderately dissolved in water, it can be effectively used for a long time.
In addition, the medicine is replenished periodically or when it is consumed.

The device of the present invention can also be provided with a function of flushing water from a person standing in front of the toilet before using the toilet. This function can be set in advance in the control mechanism of the sensor unit and can be activated or stopped by a switch.

In the pre-cleaning function, for example, when a person approaches or is detected by a sensor and a person is stopped for about 2 seconds, water is flushed in advance. This pre-cleaning function is about 60 times after running water once.
Since it does not operate for a second, it is possible to prevent wasteful use of water, such as when continuously adding.

In the device of the present invention, when the voltage of the battery drops to a certain voltage, the LED 35 indicating the battery replacement time is turned on. When the battery voltage further decreases and reaches the second level, the infrared detection circuit does not work and stops. However, even if the electric output of the battery is lost, the normally closed valve 6 is held in the closed state, and water does not flow.

The infrared pulse reflection detection can be adjusted in sensitivity.

It is also possible to notify the automatic cleaning by the sound of the piezoelectric buzzer during the water cleaning.

The specific use of one embodiment of the device of the present invention will now be described.

Battery life is about 60
It is possible to make it more than 00 times.

Since the battery unit, the sensor unit, the motor unit, the gear unit, and the control mechanism of the device of the present invention are of a unit type, they can be replaced as parts.

[Effect of the Invention] The device of the present invention automatically opens the normally-closed valve and flushes the tap water into the toilet immediately after the person wears it by the infrared pulse reflection detection method before and after washing. After flushing with water, the toilet bowl can be washed by flushing water containing a small amount of antifouling deodorant detergent.

After flushing the toilet bowl with water, the water containing the chemicals will continue to flow,
Even if the amount of water containing the drug is small, the deodorizing effect of washing can be effectively exhibited, and the concentration of the drug in the water containing the drug can be low. It can be deodorized with washing, and even fragranced.

Therefore, the toilet bowl is clean and gives the person a feeling of cleanliness and does not cause discomfort. Give people a refreshing feeling.

The device of the present invention is simple and easy to maintain, and has the following advantages.

The existing flash bulb can be used as is.

No need to break the wall or stop the water, and even an amateur can easily install it with a Phillips screwdriver.

Since the power source is a dry battery, there is no need for wiring work such as AC power source.

It also has a pre-wash function to flush water before adding more water. This function can also be stopped with a switch.

When a person continuously needs, the pre-wash function is automatically stopped to prevent wasting water.

Since the battery voltage drop is detected and displayed, appropriate replacement is possible.

Even if the battery runs out, it will not stop when the valve is pressed.

A water tank for the cleaning agent can be built in, so the appearance is excellent and the cleaning effect is also improved.

It is cheap.
