[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a water soap supply apparatus for hand washing, and more particularly to a water soap supply apparatus for forcibly sending a discharge nozzle and water soap by pressurizing a tank containing the water soap.

[0002] In this specification, water soap is a liquid detergent which has viscosity and is likely to solidify when exposed to air, and includes shampoo, rinse and the like.

[0003]

2. Description of the Related Art Conventionally, this type of water soap supply device connects a pressurizing device, that is, an air supply pipe for sending compressed air from a compressor, to an air reservoir above the inside of a tank containing water soap. A water soap output pipe connected to the discharge nozzle is communicated below the tank, the inside of the tank is pressurized to a desired degree by the compressed air, and the water soap pressurized by the operation of the on-off valve is forcibly discharged. The air supply port of the air supply pipe was located in the same space in the tank as the water soap supply port.

[0004]

However, in the conventional water soap supply apparatus described above, the tank for storing the water soap is weakly forcibly because no reinforcing means is used.

Further, as described above, since the air supply port of the air supply pipe is located in the same space as the replenishing port in the water soap storage tank, replenishment of the water soap into the tank causes the water in the tank to be replenished. When water soap has foamed, the foam may reach the compressor and the like from the air supply port through the air supply pipe, and may cause a failure of the pressurizing device.

The present invention has been made in view of the above-mentioned problems of the prior art, and has as its object to reinforce a water soap storage tank and to prevent bubbles from entering a pressurizing device. It is to plan.

[0007]

In order to achieve the above-mentioned object, a technical means of the present invention is to provide a water-soap storage tank provided with an air reservoir above the inside thereof, and pressurize the inside of the tank to a predetermined pressure. A pressurizing device and a water soap output pipe for sending the water soap in the tank to the discharge nozzle, and the water soap storage tank is provided with a partition wall having a desired communication hole and divides the inside of the tank, A water soap supply port is provided on one side of the tank upper surface with the partition wall as a boundary, and the other side is connected to the air supply pipe of the pressurizing device.

[0008]

[Operation] By the technical means described above, the partition wall provided in the water soap storage tank improves the strength of the tank, and the tank connects the room provided with the water soap supply port to the air supply pipe by the partition wall. The two rooms are communicated by a communication hole.

[0009] Even if water soap bubbles in the tank at the time of water soap replenishment, the foam does not reach the room connected to the air supply pipe only in the room on the side of the supply port due to the partition wall.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to the drawings.
And a pressurizing device 2 for pressurizing the inside of the tank 1, a water soap output pipe 11 interposed between the tank 1 and the discharge nozzle 5, and an air output communicating over the tank 1 and the discharge nozzle 5. A water-soap supply device that has a pipe 10 and mixes water soap and compressed air in a discharge nozzle 5 to discharge in a mousse shape, but discharges the water soap as it is without mixing the compressed air Of course, it may be.

The tank body 1a of the water soap storage tank 1 has an arbitrary shape such as a cylindrical shape, a rectangular tube shape or a spherical shape without any limitation. The inside of the tank body 1 is divided into two by a partition wall 4. You.

The upper side of one side 6a of one of the two rooms 6 which is divided into two parts with the partition wall 4 as a boundary is inclined, and the inclined surface 6b is provided with a water soap supply port 8, and the inclined surface 6b A space above the base end 6b 'of the pressure chamber is used as an air reservoir 9, while one end of the pressurizing device 2 is connected to an upper surface 7a on the opposite side of the room 7 between the room 6 and the partition wall 4 and a pressure sensor. 3. Connect the air output pipe 10 and the water soap output pipe 11 below.

The partition wall 4 has a bottom surface 1b in the tank body 1a.
To the upper surface 1c and approximately the same width as the lateral width of the tank body 1a.
b are formed in a desired number, and are integrally formed or disposed at approximately the center of the tank body 1a with an adhesive or the like.

Therefore, the space above the room 7 is also connected to the communication hole 4b.
, And becomes an air reservoir 9. Further, a remaining amount detector 12 for detecting the remaining amount of water soap is provided upright on the bottom surface 1b of the room 7 through a mounting opening toward the inside of the tank body 1a.

The smaller the number of communication holes 4b provided in the partition wall 4, the less the influence on the adjacent room can be reduced.
Because the speed of intrusion into the adjacent room becomes slow, it takes time to replenish, so in consideration of this point, the number of communication holes 4b,.
It is necessary to determine the position, the total area of the communication holes 4b, and the like.

In the figure, reference numeral 13 denotes a drain port for cleaning the sediment formed in the bottom surface 1b. The bottom surface 1b is provided with radial ribs 14 around the drain port 13, and the ribs 14 are provided.
Can serve as a guide when discharging (exchanging) water soap, and smooth discharge can be expected. When the ribs 14 are provided, the bottom surface 1b of the tank body 1a is
It is inclined downward toward.

The pressurizing device 2 includes a desired compressor 2a
And an air supply pipe 2b interposed between the compressor 2a and an air supply pipe mounting port 1d communicating with the air reservoir 9 on the room 7 side of the soap soap storage tank 1.
The compressed air from the compressor 2a is supplied to the reservoir 9 to pressurize the inside of the tank 1 to a predetermined pressure.

Using the pressurizing action, the soap is sent to the discharge nozzle 5 and the compressed air is sent to the discharge nozzle 5 via the air output pipe 10. It is linked and arranged together with the control unit 15 in a box 16.

In the figure, reference numeral 20 denotes a solenoid valve (such as a three-way valve) provided in the middle of the air supply pipe 2b and linked to the control unit 15.
For a short period of time (for example, 0.1 second) as required, such as when refilling water soap (when starting the compressor 2a) or when over-pressurizing the tank 1 (when the compressor 2a is stopped).
The solenoid valve 20 is driven to prevent malfunction due to sticking of the solenoid valve 20.

Therefore, water soap or bubbles of water soap, evaporative components, etc. do not flow from the air supply pipe 2b to the compressor 2a. The pressure sensor 3 includes a pressure switch using a well-known strain gauge or a magnetoresistive element. The pressure sensor 3 is provided toward the air reservoir 9 on the room 7 side of the tank 1 and is linked to the control unit 15. The pressure inside the tank 1 is transmitted to the control unit 15 as an electric signal by using the change in the electric resistance accompanying the change in the internal pressure.

The remaining amount detection unit 12 is linked to the control unit 15 by a reed switch type multipoint detection liquid level sensor or the like. For example, the inside of a float stopper 12b provided on each stage of the guide shaft 12a is controlled. Each of the float magnets 12c moves up and down in accordance with the increase and decrease of the soap so that the remaining amount of the soap is detected at each stage and transmitted to the control unit 15.

In this embodiment, the movement position of the float magnet 12c is regulated by the float stopper 1 as shown in FIG.
As shown in FIG. 2b, the water is formed in the tank 1 (the point of communication between the inside and the outside of the frame is a water hole 12e) so that the liquid level in the tank 1 is hardly affected by the ripple.

The lowermost detector 12 'of the remaining amount detector 12 is provided with a water soap outlet 11a of the water soap output pipe 11.
And the remaining amount of water soap is higher than the detector 1
When the temperature is lower than 2 ', the operation of the compressor 2a is stopped, and air intrusion into the water soap output pipe 11 may be prevented.

In the figure, 12d are projections for preventing the float magnet 12c from adhering. The control unit 15 receives a detection signal from the pressure sensor 3 and drives the compressor 2a when the pressure in the tank 1 reaches 0.3 kgf / cm ² so that the inside of the tank 1 becomes 0.5 kgf / cm ^2. When the pressure reaches 0.5 kgf / cm ² , the operation of the compressor 2 a is stopped to maintain the inside of the tank 1 at a predetermined pressure, and the water soap remaining amount detecting unit 12 detects each stage. Then, an LED is displayed on the remaining amount display unit 17.

The control unit 15 is composed of an IC, a capacitor, and the like, and is formed by covering the outer frame with a box made of a metal member, thereby preventing the control unit 15 from running away due to noise or the like. Further, the electric components such as the control unit 15 and the compressor 2a are covered with a cover made of a nonmetallic material (resin) to protect the electric components from external static electricity. The above numerical values are merely examples, and are not subject to any restrictions.

Therefore, as described above, the pressure sensor 3 and the remaining amount detector 12 of the soap are also provided in the room 7 separated by the supply port 8 and the partition wall 4, so that the soap is stored when the soap is supplied. Even if the water soap in the tank 1 oscillates, the pressure sensor 3 and the remaining amount detection unit 12 can perform reliable detection without being affected by the oscillation by the partition wall 4.

In this embodiment, a cover 20 for covering the cover 18 of the supply port 8 of the tank body 1a is provided with a system switch 19 linked to the control unit 15. When the cover is open, the operation of the compressor 2a is stopped. In addition, when the soap soap storage tank 1 and the soap soap output pipe 11, the air output pipe 10, the discharge nozzle 5, etc., which will be described later, are damaged, the compressor 2a is driven when there is leakage of air. It is optional to add various functions conceivable within the scope of the present invention, such as stopping and turning on an abnormality indicator lamp (not shown).

A concave portion 20 'is provided on the back surface of the cover 20 so as to be fitted with the handle 18' of the lid portion.
If the cover 20 cannot be closed unless it is securely sealed, the system switch 19 will not be turned ON, and the safety will be enhanced.

In the figure, reference numeral 21 denotes a control unit 15 when the uppermost detection unit 12 ″ of the remaining amount detector 12 for water soap is detected.
Is a buzzer that issues an alarm via. Although not shown, the power supply (main switch) may be 100 V AC or a dry battery, or both may be used in combination.

The water soap output tube 11 communicates with the inside of the room 7 on the bottom surface 1b of the room 7, and the air output tube 10 communicates with the air reservoir 9 of the room 7, and a plurality of the air output tubes 10 are respectively provided in the middle. , And the leading ends of the branched output conduits 11a,..., 10a.

The air output pipe 10 is provided with an electromagnetic valve 22 (for example, a three-way valve or the like) associated with the control unit 15 in the vicinity of the water soap storage tank 1 (the most upstream area). Although the air in the tank 1 is vented, the air venting solenoid valve 22 may be provided separately from the air output tube 10 and is optional.
In the case where the solenoid valve 22 is arranged as in the present embodiment, it can be expected to prevent the soap vapor component from flowing back to the compressor 2a.

The discharge nozzle 5 communicates with the water soap output pipe 11 and the respective tips 11b and 10b of the air output pipe 10 at the rear end of the nozzle body 5a, and communicates with the discharge port 5c in the cylinder wall 5b. Push button 5f that secures a flow path 5d that serves as a mixing section of air and air and resists the urging force of spring 5e
The spindle 5g which advances and retreats by pushing is inserted, and the switching valve 5 is seated on the cylinder wall 5b in the middle of the spindle 5g.
h, a plurality of stirring nets 5k are attached to a discharge port 5c integrated through a small hole 5j communicating with the flow path 5d between the valve 5i and the valve portion 5i. In the figure, check valves 23 are provided at the rear end side of the nozzle body 5a, that is, in the vertical pipe portion 51 inserted into a counter or the like.

The check valves 23, 23 are, for example, valve chambers 23a, 23a provided in a vertical pipe portion 51 as shown in the figure.
Provided in the inside, and spherical valve bodies 23b, 23b
And the funnel-shaped valve seats 23c, 23c which contact and close the valve bodies 23b, 23b, respectively, and are closed only by the own weight of the valve body 23b.

Therefore, the check valves 23, 23 described above are not always biased in the valve closing direction by a spring, but are merely spherical valve bodies 23b, 23b which are weighed only by their own weight.
3c, 23c, and the valve is closed, so that the amount of water soap in the water soap storage tank 1 decreases, and even if the inside of the tank 1 becomes a low water pressure region, the pushing force of the valve bodies 23b, 23b is hindered. Supply can be ensured without coming.

Each of the nets 5k may be arranged at desired intervals as shown in the figure, or may be formed by superimposing the nets 5k. In place of the net 5k, for example, a square tube may be used. It is not limited as long as it has a fine mesh, such as a combination of a rectifying plate or a roll of metal pieces, or a plate having a desired number of plate bodies in which a desired number of through holes are perforated. (Fineness) can be selected.

The momentum at the time of discharging the soap can be selected according to the diameter of the discharge port portion 5c. The open / close valve 5h may be electrically or electromagnetically opened for a certain period of time by an electric signal based on the detection of a hand by a human sensor such as a photoelectric sensor or a pressing operation of a touch switch. The valve may be opened manually while the button 5f is being pressed or during a certain period of time. However, in the illustrated example, a manual open / close valve 6c operated by operating the push button 5f is shown.

In the discharge nozzle 5, the push button 5f
By pressing, the compressed air and water soap mix in the discharge nozzle 5 and are stirred by the mesh 5k. Therefore, the water soap is discharged in a mousse state.
