Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Field of Application) The present invention relates to a water soap supply device for hand washing.

(Prior Art) Conventionally, a water soap centralized supply device has been equipped with a tank for storing water soap, a pressurizing device such as a compressor that pressurizes the inside of the tank, and a manual on-off valve that communicates with the tank via a supply pipe. Some discharge nozzles are equipped with a plurality of discharge nozzles. There is also a water soap supply device in which a pump is driven by sensor sensing and discharges water soap in a tank from a discharge nozzle.

(Problems to be Solved by the Invention) The former is opened and discharged by pushing the manual on-off valve.

However, the time required to press the manual on-off valve varies from person to person, and more soap and water is used than necessary, which is uneconomical. Furthermore, since the latter is driven by a pump, it consumes a large amount of power.

The present invention has been made in view of the above-mentioned conventional circumstances, and its purpose is to quantify the amount of water soap used in the nozzle so that a large amount of water soap is not consumed each time it is used, and to The goal is to keep power consumption low.

(Technical measures taken to solve the problem) The technical measures taken to achieve the above objective are: a tank for storing water soap; a pressurizing device that constantly pressurizes the inside of the tank to a predetermined pressure; A supply pipe line communicating with the tank, and a discharge nozzle provided in communication with the supply pipe line, the discharge nozzle having a sensor for detecting use, and the supply line having a predetermined temperature determined by the sensor detection. The gist is that a solenoid valve that opens at certain times is provided. Here, water soap is a liquid detergent that has viscosity and solidifies when exposed to air, and includes shampoos, conditioners, and the like.

(Function) When the sensor detects the use of each discharge nozzle, the solenoid valve is opened for a predetermined period of time and a predetermined amount of water soap is discharged from the discharge nozzle.

(Effects of the Invention) Since the present invention is configured as described above, water soap can be quantitatively discharged each time the discharge nozzle is used, and the water soap can be consumed in an appropriate amount without waste.

In addition, the system is not of the type that drives a pump or the like connected to each discharge nozzle each time a sensor is sensed, but only opens a solenoid valve, so power consumption is low and it is economical.

(Example) Next, embodiments of the present invention will be described based on the drawings.

A in the figure indicates a water soap supply device.

This water soap supply device A includes a tank 1 that stores water soap 100, a pressurizing device 2 that constantly pressurizes the tank 1 to a predetermined pressure, and a water soap supply pipe 3 that communicates with the tank 1.
, an air supply pipe 4, and a plurality of discharge nozzles 5 connected to both supply pipes 3, 4.

The tank 1 is formed in a box shape with an inclined surface 1b at the top of one side peripheral wall 1a, and the inclined surface 1b is provided with a water soap supply port 1'', and furthermore, a water soap supply pipe 3 and a cleaning port are provided at the bottom 1c. The drain pipes 6 are connected to each other, and the water soap supply port 2
The water soap IH can be stored up to the upper limit, and about 31 air 100 is stored in the tank 7 1° above the water soap supply port, which is connected to the air supply pipe 4 connected to the ceiling of the tank 1. It looks like this.

Further, a pneumatic feed pipe 2a of a pressurizing device 2 is connected to the tank 1 facing the upper space of the water soap supply port 1'', and a pressure sensor 7 and a sensor 8 for detecting the remaining amount of water soap are arranged inside. At the same time, a storage box 9 is attached adjacent thereto.

The storage box 9 has a compressor 2 of the pressurizing device 2 inside.
b. A controller 10, which will be described later, is accommodated, and a water soap remaining amount display section 11 is disposed on the surface.

The pressure sensor 7 is composed of a well-known strain gauge or a pressure switch using a magnetoresistive element, and transmits the pressure inside the tank 1 as an electric signal to the controller 10 by utilizing changes in electrical resistance accompanying changes in the pressure inside the tank 1. It is composed of

Further, the sensor 8 for detecting the remaining amount of water soap is a float switch or the like, and is configured to detect the remaining amount of water soap in the tank 1 in five stages and transmit the information to the controller 10.

The controller 10 detects the detection signal from the pressure sensor 7, and when the pressure inside the tank 1 becomes (1.3 kg1/aIr), it drives the compressor 2b, and when the pressure inside the tank 1 becomes I], 5 kg1/cXl, the same compressor 2
b is stopped to maintain a predetermined pressure in the tank 1 at all times, and each time the water soap remaining amount detection sensor 8 detects five levels, an LED is displayed on the water soap remaining amount display section 11.
It is configured so that when the water soap remaining amount display section 11 at the bottom stage is detected, a command is issued to stop the series of systems.

The system switch 12 consists of a water soap supply port 1° and a lid 17 that closes the water soap supply port 1°. to stop driving the compressor 2b, and then open the solenoid 3-way valve 13 of the air supply pipe 4 to remove air from the tank 1. When the water soap supply port 1° is closed, the solenoid 3-way valve 13 is turned ON and the solenoid 3-way valve 13 is opened. When the direction valve 13 is closed, the compressor 2b is controlled via the controller 10 to drive the compressor 2b.

In addition, 14 is the water soap 1 to be supplied from the water soap supply port 1.
00 is a buzzer that, when the water soap remaining amount detection sensor 8 detects the top level, issues an alarm via the controller 10 to prevent further accumulation.

The water soap supply pipe 3 and the air supply pipe 4 connected to the tank 1 are further branched downstream of the electromagnetic three-way valve 13, and a check valve 15 is provided in each of the branch pipes 3a and 4a.
．． 15 is provided, and a discharge nozzle 5 is connected to the tip.

The discharge nozzle 5 is, as shown in FIG. The branch pipe 3a and the branch pipe 4a of the air supply pipe 4 are connected, respectively, and the outlets of the branch pipes 3a and 4a are communicated with the water outlet 5b via the mixing chamber 5c and the small hole 5d.

Further, each of the discharge nozzles 5 is provided with a sensor 6 at a desired location such as the lower end area of the main body 5a to detect a hand held directly below the discharge port 5b.
, 4a is equipped with a solenoid valve 16.16, which is linked to the controller 10 so that the solenoid valve 16.16 opens for a predetermined period of time when detected by the sensor 6.

Note that the sensor 6 is not limited to one that automatically senses the human body, and may also be a touch sensor.

Therefore, in this embodiment, when the sensor 6 detects the use, the solenoid valves 16 and 16 are opened for a predetermined period of time, and the compressed air in the tank 1 above the water soap supply port 1 is released.
01 and water soap 100 flow into the mixing chamber 5c from each branch pipe 3a, 4a, are mixed, and are ejected from the small hole 5d.
The mixture is stirred by the stirring net 5b' and discharged in the form of a mousse from the spout 5b.

Although not shown in the drawings, this embodiment describes the mousse discharge in detail. A tank storing water soap is pressurized to a predetermined pressure using a pressurizing device, and this tank and a plurality of discharge nozzles are connected to the water soap. The water soap is connected to the water soap by a solenoid valve that communicates with the supply pipe and is further provided with a sensor that detects the use of each of the eight nozzles. The present invention also targets a so-called 8-type rectifier discharge soap supply device installed in each of the branch pipes of the supply pipe.

Further, if a plurality of discharge nozzles are used at the same time, a means may be provided to prevent the pressure in the tank 1 from rapidly decreasing, which is considered to be abnormal.

For example, when two discharge nozzles 5 are used at the same time, the solenoid valve 16 is linked to the controller 10 so that it closes at 70% of the normal water discharge time, or when one discharge nozzle 5 is in use. When the other water spouting nozzle 5 is in the open state where it is used, the water spouting currently in use is stopped in about 1 second, and the discharge nozzle 5 that is in the open state is made to spout after about 1 second. The valve 16 may be connected to the controller 10, or other discharge nozzles 5 may be
When the valve is in the open state where it is used, the discharge nozzle 5 for 70% water spouting time is immediately closed to immediately finish water spouting, and the other discharge nozzle 5 starts discharging water for 70% of the normal water spouting time. For example, the solenoid valve 16 is linked to the controller 10.

In addition, the limit capacity of the compressor 2b may be set so that when five discharge nozzles 5 are used at the same time, water will not be discharged from two discharge nozzles 5, or the solenoid valve 16 of the two discharge nozzles 5 may be set so that the solenoid valve 16 of the two discharge nozzles 5 is not opened. Controller 1 so that there is no
One example is to link it to 0.

With this configuration, the pressure inside the tank 1 will not decrease suddenly.
Normal operation can continue.

In addition, in the case of mousse discharge, if more than one discharge nozzle 5 is used at the same time, the controller 5 may control the solenoid valve 16 to prevent the pressurized air from decreasing rapidly by switching to rectifying discharge a. Optional.

Although the stirring net 5b' of this embodiment is shown to have a configuration of three pieces, for example, a net wound into a roll, a hexagonal columnar net assembled adjacent to each other, a star-shaped one, etc. Any shape or structure may be used as long as it can be stirred, such as one with a mesh formed into a columnar shape, and the mousse state can be adjusted to any volume by setting the mesh.
Furthermore, the discharge ports 18 having various diameters may be prepared and made detachable so that the force at the time of discharge can be selected.
