BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure of a water soap supply pipe in a water soap discharging apparatus.

[0002]

2. Description of the Related Art Conventionally, as a water soap discharging device, for example, a water soap discharging nozzle is provided above a hand washing machine, and a water soap stored in a water soap tank disposed below a counter or the like in which the hand washing machine is installed is pumped. There is a type that feeds and discharges to the discharge nozzle through a feeding device such as the above.However, in such a case, a supply port of water soap is provided above a water soap tank such as a hand washing machine or a counter, and a supply port is provided. The water soap tank is connected by a supply pipe (see Japanese Patent Application Laid-Open No. 64-75727).

[0003]

However, in such a conventional soap dispenser, replacement of the soap by the supply of the soap causes bubbling of the soap, particularly when the supply port is small or the supply pipe is narrow. Is not performed well, and a large amount of foam is generated, so that the soap cannot be sufficiently replenished or foam overflows from the replenishing port.

[0004] For this reason, replenishment of water soap has been troublesome in that it has to be replenished little by little while taking care not to form bubbles. The present invention has been made in view of the above-mentioned problems of the prior art, and its purpose is to suppress the generation of bubbles by smooth replacement of air and water soap in the water soap tank when replenishing water soap. is there.

[0005]

Means for Achieving the Object In order to achieve the above object, the water soap supply pipe structure of the water soap discharge device of the present invention has a double structure in which the water soap supply port communicates with the water soap tank. None, the inner space is a water soap supply path, and the outer space is an air vent path.

[0006]

[Function] In the structure of the water soap supply pipe of the water soap discharge device configured as described above, if the water soap is injected from the water supply passage, the air in the water soap tank is concomitantly injected into the water supply passage. The water is discharged to the outside through an air vent passage formed on the outside, and the air in the water soap tank is replaced with the water soap smoothly.

[0007]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. The water soap discharge device A includes a water soap tank 1 for storing water soap, an air pump 10 and a discharge tool 9 having a water soap discharge port 7 and a hand washing water discharge port 8 on a rear upper edge surface of the hand washing machine 2. A thermostat mixing valve 11 for communicating with a water supply source and a hot water supply source is respectively installed in the space below the hand washing machine 2. Is connected to an air pump 10 via an air supply pipe 13, and a thermostat mixing valve 11 is connected to a hand washing water discharge port 8 via a hand washing water supply pipe 14. By operating the soap discharge switch 15, the air pump 10 and the water soap feed pump 16 interposed in the water soap supply pipe 12 are operated to supply air and water soap to the water soap discharge port 7. Mix The water is discharged from the water soap discharge port 7 in a mousse shape, and the electromagnetic valve 18 interposed in the hand water supply line 14 is opened by operating the hand water discharge switch 17 provided on the discharge device 9 in the same manner. Hand wash water outlet 8
It is designed to discharge hand washing water from.

[0008] The discharge device 9 is provided with an opening 20 having a lid 19 which can be opened and closed on the upper surface thereof. The opening 20 is provided with a water soap supply port 3. The water soap tank 1 is communicated via a pipe 4.

The supply pipe 4 is formed integrally with the discharge device 9 and protrudes below the discharge device 9, penetrates the upper edge surface of the hand washer 2, extends into the space below the hand washer 2, and extends into the space of the soap tank 1. An outer tube 4a connected to the receiving port 21 provided on the upper surface, and the outer tube 4a
A double pipe structure consisting of an inner pipe 4b which is inserted into the inside of the water soap tank 1 near the bottom with a slight gap between the inner pipe 4a and the inner peripheral surface of the outer pipe 4a and is inserted loosely. Then, the upper end of the outer tube 4a is open to the opening 20 of the discharge device 9, and the upper end of the inner tube 4b is connected to the soap supply port 3.

Therefore, in the supply pipe 4, the inside of the inner pipe 4b forms a water soap supply path 5, and the space between the inner pipe 4b and the outer pipe 4a forms an air vent passage 6 for releasing the air from the water soap tank 1. Will do.

The upper end of the outer tube 4a of the supply tube 4 is opened to the opening 20 of the discharge device 9, and a large diameter is formed from the upper end opening to the bottom of the discharge device 9. The water soap supply port 3 is opened at 4a-1.

The water soap supply port 3 is formed in a funnel shape having a flange 22 on an opening edge. The flange 22 is hooked on an upper end opening edge of the outer tube 4a of the supply tube 4 and inserted into the supply tube outer tube 4a. And the upper end opening of the supply pipe inner tube 4b is connected to the spout 23 which protrudes from the bottom. A notch 24 is formed in the flange 22 at the opening edge of the water soap supply port 3, and the air vent passage 6 is connected to the outside through the notch 24.

In the water soap discharging apparatus A, when the lid 19 of the discharging device 9 is opened and the water soap is poured into the water soap supply port 3, the water soap supply constituted by the inner pipe 4b of the supply pipe 4 is performed. Water soap is supplied to the bottom of the water soap tank 1 via the road 5, and the tank 1
The internal air is discharged out of the tank 1 through an air vent passage 6 formed by a gap between the inner pipe 4b and the outer pipe 4a of the supply pipe 4, and the replacement of the air with water soap is performed.

[0014]

[Effect] Since the present invention is configured as described above, when the water soap tank is refilled with the water soap, the air in the tank is replaced with the water soap satisfactorily, and the generation of bubbles is suppressed. Therefore, there is no inconvenience such as foam overflowing from the water soap replenishing port. Easy to do.
