Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a water supply device that senses a human body and electrically supplies wash water to a hand wash or washbasin.

Conventionally, this type of device was connected to a commercial AC power source.

Therefore, when installing, it is not easy to install as it requires distribution work for power lines of the commercial power supply, and it is not easy to install, and it is also in places where there is no commercial power supply (power lines are not connected), such as washrooms and restrooms in parks and highways. It cannot be installed in places where there is no such thing.

The present invention aims to solve the above problems and enable installation in any area.

The above object, according to the present invention, includes a hand wash or wash basin, a water supply device that senses the human body and electrically supplies water to the hand wash or wash basin, and a battery that supplies power to the water supply device. This is achieved by the configuration of the water supply device.

Embodiments of the present invention will be described below with reference to the drawings.

This embodiment is a water supply device for a handwash basin, and the handwash basin (A) in the figure is attached to the building wall (B), with a water spout (1) and a soap dispenser ( 20) is provided.

The spouting device (1) has a body (1a) rising upward from the upper edge surface of the handwash (A), and a discharge opening (1b) at the upper end facing the bowl part of the handwash (A) from above. Torso (la
) The O base is the washbasin (A) On the i side, the solenoid valve (D) of the water supply device (C) (described later) and the secondary side water supply connection pipe (2)
We are in contact via.

The water supply device (C) includes a sensor (E) and a solenoid valve (D).
and a control section (F).

In this embodiment, the sensor (E) includes a light emitter (el) and a light receiver (el). Infrared rays projected by the light emitter (eIX) hit a human body, for example, a hand, and are diffusely reflected, and this reflected light is transmitted to the light receiver (el). This is a so-called diffuse reflection infrared photoelectric sensor that detects light by receiving light from the hand basin (el).
A) is provided on the front surface of the body part (1a) of the water spouting tool (1) so that it can automatically sense a hand or the like held out to the water spouting tool (1).

The inlet (3) is connected to the water supply pipe (4) buried in the wall (B) through the primary water supply connection pipe (7) equipped with a water stop valve (5) and a strainer (6). Connect the outlet (
8) is connected to the water spouting device (1) via the secondary side water supply connection pipe (2) and is installed in the space below the washbasin (A).

In addition, the above solenoid valve (D) is connected to the secondary and secondary water supply connection pipe (7).
It is housed in a case (9) that is attached and fixed to (2).
The case (9) also accommodates and arranges a control section (F).

The control unit (F) is connected to a solenoid valve (D) and a sensor (a battery CG that is electrically connected to El and serves as a power supply source for this water supply device).

'Batteries (G) Replaceable lithium batteries, mercury batteries, rechargeable CADNICA batteries, lead batteries, semi-permanent solar batteries, etc. can be selected depending on the conditions at the installation site. For example, If the installation site is a place where batteries can be easily replaced and charged, you can use lithium batteries, mercury batteries, or Cadonica batteries or lead batteries, which can be used even in the mountains and are not wasteful. 5I
f. It is convenient to use solar cells in places where replacement cannot be easily performed.

This battery is placed at an appropriate location on the building wall (B) or inside the case (9) together with the control section (F).

In this embodiment, a lithium battery shown in FIG. 7 is used as the battery (G).

In Fig. 7, υ is an upper case made of stainless steel, and after spot welding a metal current collector (24) such as nickel net or nickel sponge on its inner surface, a disk-shaped metal lithium sheet (c) is placed on its surface. The lower case is made of the same material as the upper case (21) of CI!4+'i. Graphite was added as a phase, and after thorough mixing, a solution of sodium silicate in water was added, and after stirring and mixing, it was thoroughly dried, and the resulting positive electrode mixture was pressure-molded onto a disk. be.

(e) is a positive electrode ring that fixes the positive electrode (c) to the case (to).

Is the electrolyte solution, for example, propylene car with lithium perchlorate dissolved in it? After vacuum impregnating the positive electrode (c) incorporated in the lower case layer 4, the separator α'0 made of polypropylene nonwoven fabric, and the negative electrode (c) bonded to the upper case sheet υ, a polyethylene packing sheet was placed around the periphery. Place the fitted upper case (2υ) over the lower case (241), and
The open end of the case Ca41 is caulked to form a battery (G).

On the other hand, the control section (F) controls the energization of the solenoid valve (D) in response to the sensing signal of the sensor (E), and starts sensing the sensor (E) for a predetermined sorting time TI (e.g. After several m sec, ~0.5 sec, ), the solenoid valve υ continues while the sensor (E) detects the human body.
) is energized, and a predetermined delay time 'h(
For example, Q, 5 sec, ~2 sec,) after solenoid valve C
D) is configured to stop energizing.

Furthermore, the control unit (F) controls the abnormal continuous water spouting prohibition time T3 (for example, 2WD, 4WD, 4WD, 4WD, etc.), which is set to be slightly longer than the normal hand-washing or washroom time. min, ), and is configured to stop water spouting when the continuous water spouting time reaches the prohibition time T3 even during sensing.

That is, as shown in the block diagram of FIG. 5, the control unit (F) generates the activation signal when the detection signal of the trap and sensor (E) is generated and this generation continues for the sorting time T1, and also outputs the detection signal. disappears and this disappearing state continues for a delay time T2, a malfunction prevention circuit (f −1
), a timer circuit (f-2) that generates a time-up signal only when the activation signal is continuously generated for a prohibition time T3 and resets when the activation signal disappears, and a timer circuit (f-2) that generates an output generation prevention signal based on the time-up signal. An output generation prevention circuit (f-3) generates an output to drive the solenoid valve (D) when only the start signal is generated, and prevents output generation when the start signal disappears or together with the start signal. An output circuit that stops generating output when a signal is generated (
f-4).

The solenoid valve CD) has a valve seat C1O between an inlet (3) and an outlet (8), the corresponding valve body αυ is made of a diaphragm, and a coil bobbin (6) is wound around the solenoid coil. It abuts against the end of a gland gloss αη which is slidably disposed within a silane gloss paQ inserted into the hollow part of the silane gloss via a pair of cylindrical electrodes 04 (6).

The cylinder/jar α is always urged by the spring α barrel in the direction of closing the valve seat αQ with the valve body α.

Therefore, in this solenoid valve (■), the pusher αη slides within the gland gear guide aQ by controlling the energization to the electromagnetic coil α by the control unit (F), and if it is not energized, the valve is closed by the force of the spring light. The body αη is pressed against the valve seat and the valve closes, and water is not supplied to the water spouting device (1).

This valve closed state is maintained by the plunger α being attracted to the q magnetic poles.

Also, if the electromagnetic coil (b) is energized, the plunger α
η is attracted to the magnetic pole α→ against the biasing force of the spring α, and the valve body α■ is pushed away from the valve seat α0 by the water supply pressure to open the valve and water is supplied to the water discharging device (1).

In other words, when a person stands in front of the washbasin to wash their hands, the sensor (E) automatically detects this and sends a signal to the control unit (F), which then responds based on this signal. Solenoid valve (DJ
Open the valve and start water supply.

This water supply starts after a sorting time Tl after the sensor (E) starts sensing the user's hand, etc., and stops after a delay time T2 after the sensing disappears.

If the water supply continues abnormally longer than the time required for normal hand washing or washing, the water supply will automatically stop after the prohibited time T3 even if sensing is in progress. A time chart is shown in FIG.

The reason for providing the sorting time T1 is to prevent your hands from getting wet if, for example, you hold out your hand but suddenly stop washing your hands.

In addition, the delay time T2 was provided because, for example, during hand washing, the hand may momentarily move out of the sensing area and the sensing disappears. This prevents failure of the electromagnetic valve (D) and occurrence of water hammer due to frequent starting and stopping of the water hammer, and also helps in cleaning dirt adhering to the hand washing basin (A) after hand washing.

Furthermore, the prohibition time T3 was provided to prevent water from flowing out due to some reason, such as soap liquid adhering to the photoelectric sensor (E) and being detected. .

The above-mentioned first embodiment is an automatic sensing system that automatically senses when you put your hand between the wash basins and starts supplying water regardless of whether you intend to wash your hands or not. However, it is also possible to use a system that can be called an intention sensing system, which senses this and supplies water only when there is an intention to wash hands.

To explain the second embodiment of this method, the infrared ray photoelectric sensor (E) is installed in the handwash basin C as shown in Fig. 8.
A) Attach it to the wall of a nearby building (B), and at the first detection of the sensor (E), the control unit (F) energizes the solenoid valve (D) to open it, and at the next detection, it opens the solenoid valve CD. ) is configured to close the valve by stopping power supply to the valve.

In this embodiment as well, a trap selection time TI% delay time T2 and a prohibition time T3 are provided as in the previous embodiment.

A block diagram is shown in FIG. In this embodiment, there is a malfunction prevention circuit (f-1) which operates in the same manner as in the previous embodiment and generates a start signal, and which generates an output generation signal at the rise of the first start signal and resets at the rise of the next start signal. A bistable multivibrator circuit (f-5) that stops generating an output signal when the output signal is output, and a timer circuit (f-5) that starts from the start of output signal generation, generates a time-up signal after prohibition time T3, and resets when the output signal disappears. f-z), a bistable multivibrator reset circuit (f-6) that resets the bistable multipipe rake circuit (f-5) based on the time-up signal, and a bistable multivibrator circuit (f-5). The output circuit (f-4) generates an output for driving the electromagnetic valve (CD) while the output signal is being generated.

Therefore, when you want to wash your hands, the sensor (
Hold your hand in front of the sensor (E) to start the sorting time TIK water supply and start hand washing, and after hand washing, hold your hand in front of the sensor (E) again to set the sorting time Tl. The water supply can then be turned off.

Of course, even if you forget to stop the water supply after the water supply starts, the water supply will be automatically stopped after the prohibition time T3.

A time chart is shown in FIG.

The delay time T2 is such that when a hand is held in front of the photoelectric sensor (E), a sensing signal is repeatedly generated and disappeared due to the existence of a space between the fingers, and water supply starts and stops repeatedly. This will help prevent this.

In addition, the sorting time T1 is 11 hours, when you first put your hand over your hand, water is flushed immediately, but after T1 hours, the water is flushed, which saves water, and when you put your hand over your hand after washing, the water supply is not stopped immediately, but for 11 hours. Since the water supply is then stopped, it is useful for removing dirt from the hand wash basin.

It is possible to use a single circuit as the control section (F) for both the automatic sensing method of the first embodiment and the intention sensing method of the second embodiment, and a block diagram of this is shown in FIG. In this block diagram, the mode changeover switch circuit (f-
7) and the output control circuit (f-8), it is possible to switch between the automatic sensing method and the volitional sensing method. If you do this, you only need to prepare one control unit (F) (and management is easy).

FIG. 12 shows an example of a circuit in which the mode changeover switch circuit (f-7) is configured with a manual changeover switch.

In addition, as shown in FIG. 13, the body part (1a
) An automatic detection type sensor (E) is installed on the front, and a will detection type sensor (E) is installed on the building wall (B).
The mode changeover switch circuit (f-, near) may be automatically set depending on the sensor (E) used first.

In the above embodiments, the sensor is an infrared photoelectric sensor, but it is also possible to use an electrostatic or ultrasonic sensor.

In addition, (to) in the figure is a drain pipe.

Since the present invention has the above configuration, it has the following advantages.

(1) Since a commercial AC power source is not used, there is no need to connect wiring to a commercial AC power source, and installation is extremely simple, and it can be installed even in places where there is no commercial AC power source.
