Abstract

PROBLEM TO BE SOLVED: To enable the replenishment with a proper amount of liquid soap. SOLUTION: A cap 14 is opened and liquid soap is poured into a feed liquid opening 12. This liquid soap flows down through a fall channel 13 onto a tray 2. While the level of the liquid soap is low, the liquid soap on the tray 2 speedily flows down from a fall opening into a tank 1 and the liquid soap hardly stays on the tray 2. When the level of the liquid soap in the tank 1 reaches a droop wall 24, the air in a small pit 27 can not escape to an upright tube 22 any more and then the liquid soap starts to stay on the tray 2. Soap bubbles are generated by air bubbles coming out of the upright tube 22 and the fall opening and in the end reach the feed liquid opening 12. Then these soap bubbles come into the notice of a replenisher of liquid soap and pouring of any more liquid soap is stopped.

DISCLOSURE OF INVENTION Problems to be Solved by the Invention In the water soap dispenser having the liquid supply port above the counter as described above,
When replenishing the water soap from the liquid supply port, the water soap liquid level inside cannot be visually observed, so that the water soap is excessively injected,
Water soap may overflow from the liquid supply port, and the top surface of the counter may be soiled with water soap.

An object of the present invention is to solve the above problems and to provide a water soap feeder which can always supply an appropriate amount of water soap.

[0007]

In the water soap supply device of the present invention, a water soap supply port and a discharge pipe are provided in the upper part, and the water soap supplied from the liquid supply port is stored in the lower part. In a water soap feeder provided with a tank and provided with a pump for feeding the water soap in the tank to the discharge pipe, in the middle of a drop flow path of the water soap from the liquid supply port to the upper part of the tank, A tray that traverses the falling flow path in a substantially horizontal direction is provided, and a drop port for dropping water soap from the upper side of the tray to the lower side of the tray is provided in the tray, and the tray rises from the upper surface of the tray, and the inner hole is connected to the upper side of the tray. A rising cylinder communicating with the tray lower side is provided, and a hanging wall is hung from the lower surface of the tray, and is separated from the lower region of the rising cylinder by the hanging wall below the drop port. In addition, it is characterized in that a space portion whose lower part is opened is provided. .

In such a water soap supply device, when water soap is supplied from the liquid supply port, the water soap flows down the drop passage, passes through the drop port of the tray, and accumulates in the tank.

Until the liquid level of the water soap in the tank reaches the hanging wall, the air in the tank passes through the center hole of the rising cylinder, replacing the water soap falling from the drop port. Promptly drops into the tank. Therefore, the water soap is hardly accumulated on the tray, and the upper end of the rising cylinder is not submerged in the water soap.

However, when the liquid level of the water soap in the tank reaches the hanging wall, the hanging wall interrupts the communication between the space below the drop port and the area below the rising cylinder, and Air will come out of the drop opening in lieu of water soap flowing down. Therefore, the falling speed of the water soap from the drop opening becomes slow, the water soap accumulates on the tray, and finally the upper end of the rising cylinder also comes to be immersed in the water soap accumulated on the tray.

As a result, the air rising from the drop port and the air from the space below the rising cylinder come to rise as bubbles in the water soap on the tray, and a large amount of water is supplied in the water soap feeder. Soap bubbles are generated. The soap bubbles ascend upward in the drop channel and eventually reach the liquid supply port. When it is confirmed that the soap bubbles have reached the liquid supply port, the injection of water soap into the liquid supply port is stopped. This prevents excessive pouring of water soap until it reaches the liquid supply port. Although some bubbles may overflow from the liquid supply port,
The amount is small compared to the case where the liquid overflows.
The appropriate amount is the tank volume up to the hanging wall.

Since the tray is provided with a rising tube, a hanging wall, etc., it can be manufactured and assembled easily by constructing it separately from the tank and mounting it on the upper end of the tank. You can do it.

The upper portion of the column 4 is arranged above the counter 5, and the head housing portion 6 is provided on the upper portion of the column 4 and the discharge pipe 7 is connected thereto.

A head 8 is accommodated in the head accommodating portion 6 so as to be vertically slidable. A hollow pipe-shaped shaft 9 extends downward from the head 8. A bellows 10 is provided between the lower end of the shaft 9 and the tray 2, and the shaft 9 can be pressed upward by a coil spring 11 in the bellows 10.

A liquid supply port 12 is provided in the head 8, and the inside of the water soap feeder (however, outside the shaft 9 and the bellows 10) extending from the liquid supply port 12 into the tank 1 drops the water soap. It is the flow path 13. The head 8 is provided with a cap 14 that covers the liquid supply port 12.

A relay room 15 is provided below the tray 2.
The inside of the relay chamber 15 and the inside of the bellows 10 are communicated with each other through a vent 16 at the center of the tray 2. A suction pipe 17 for water soap is hung from a floor portion 15a of the relay room 15. A check valve 18 that allows only upward flow of the water soap is provided on the upper portion of the suction pipe 17.

A check valve 19 for allowing upward flow of water soap is provided on the ceiling surface of the relay chamber 15. The check valve 19 has an outflow side (upper side) which is connected to the liquid delivery pipe 20 and the delivery pipe 20. It communicates with the discharge pipe 7 through the liquid flow path 21. Below the check valve 19, a water soap conduit 19a is vertically provided.

In the tray 2, a stand-up cylinder 22 is erected at a position outside the relay chamber 15, and a through-hole-like drop opening is provided at a position outside both the stand-up cylinder 22 and the relay chamber 15. 23
Is provided. Center hole of the rising tube 22 and drop port 23
Respectively connect the upper side and the lower side of the tray 2.

A hanging wall 24 is vertically provided between the rising cylinder 22 and the drop opening 23. Both ends of this hanging wall 24 are
An annular hanging wall 25 that hangs down from the peripheral edge of the tray 2 and a hanging wall 26 that forms a peripheral wall portion of the relay chamber 15 are connected to each other, so that a small chamber 27 that is open downward is defined below the drop opening 23. Has been done.

The water soap supplier is fixed to the counter 5 by a nut 28 screwed to the column 4.
The column 4 and the cover case 3 are connected by a joint nut 29.

In the water soap dispenser constructed as described above, when the head 8 is pushed down, the air in the bellows 10 is pressurized, and the water soap in the relay chamber 15 is introduced into the conduit 19a, the check valve 19, and the liquid delivery pipe. It is discharged from the discharge pipe 7 through 20 and the liquid supply passage 21. At this time, the check valve 18 is closed.

When the hand is released from the pushed-in head 8, the shaft 9 and the head 8 are pushed up by the spring 11, and the inside of the bellows 10 becomes negative pressure. As a result, the water soap in the tank 1 is sucked up into the relay chamber 15 via the suction pipe 17 and the check valve 18. At this time, the check valve 1
9 is closed.

By pushing the head 8 a required number of times in this way, the water soap in the tank 1 can be discharged from the discharge pipe 7.

When supplying water soap into the tank 1,
The cap 14 is opened, and water soap is poured into the liquid supply port 12. This water soap falls through the drop channel 13 and reaches the tray 2, but as long as the water soap liquid level in the tank 1 is low,
The water soap on the tray 2 is promptly discharged from the drop port 23 to the tank 1
It falls inside and almost no water soap accumulates on the tray 2. That is, as shown in FIG. 4 (a), the water in the tank 1 escapes upward from the center hole of the rising tube 22 in exchange for the water soap dropping from the drop port 23, so that the water on the tray 2 is discharged. The soap passes through the drop opening 23 very quickly.

When the liquid level of the water soap in the tank 1 reaches the hanging wall 24, the air in the small chamber 27 cannot escape to the rising cylinder 22. As a result, the air in the small chamber 27 does not have to escape to the upper side from the drop port 23, and the tray 2 is replaced with the air that comes out as bubbles from the drop port 23.
The upper water soap will fall into the small chamber 27. As a result, the falling speed of the water soap falling from the tray 2 into the tank 1 is reduced, and the water soap gradually accumulates on the tray 2. Finally, the rising cylinder 22 causes the water soap on the tray 2 to fall. You will be immersed in it.

Bubbles coming out of the drop port 23 cause soap bubbles to be generated from the liquid surface of the water soap on the tray 2. In addition, as the liquid level in the small chamber 27 rises, the liquid level below the rising cylinder 22 also rises, and the air below the rising cylinder 22 flows upward from the rising cylinder 22 as bubbles. The bubbles generate soap bubbles from the liquid surface of the water soap on the tray 2.

In this way, the drop flow path 13 is filled with the soap bubbles generated one after another, and finally the soap bubbles reach the liquid supply port 12, and the operator who injects the soap bubbles receives the soap bubbles. Notice and stop further infusion of water soap. As a result, when the water soap has been injected into the vicinity of the tray 2 in the water soap supply device, further water soap injection is stopped, so that the water soap is injected until it overflows from the liquid supply port 12. Is reliably prevented. Of course, a sufficient amount of water soap is supplied to the inside of the water soap supply device to fill the tank 1.

Although the tray 2 is provided at the upper end of the tank in the above embodiment, the tray 2 may be installed above or below the tank.

Although the hand-operated pump is adopted in the above-mentioned embodiment, an electric pump may be adopted.

In FIGS. 1 and 2, the tray 2 is integrally formed including the relay chamber 15 portion. However, the ceiling surface portion of the relay chamber 15 is formed separately, and the tray is bonded by adhesion. It may be configured to be joined to the main body side of 2.

[0032]

As described above, according to the water soap feeder of the present invention, it is possible to inject a proper amount of water soap into the water soap feeder. Then, it is possible to prevent excessive injection of water soap and overflow of water soap from the liquid supply port to stain the upper surface of the counter.
