  When such a conventional soap soap discharge device 50 is configured as shown in the block diagram of FIG. 10, when a hand is brought close to the nozzle 52, the control unit 68 generates a pump 66 based on a human body detection signal from the soap device side sensor 51. Is driven and water soap is discharged from the discharge port 52. However, the user may not be aware that the apparatus is a human body sensing type, and may misunderstand that the device is a manual water soap tub and push the discharge port 52. That is, when the user tries to push the discharge port 52, the palm of the user blocks the discharge port 52, and when the discharge port 52 is incompletely closed and there is a slight gap between the palm and the hand, Since the side sensor 51 detects the hand and the pump 66 is driven, water soap is generated from the slight gap, so there is a possibility that it will be ejected with considerable momentum. Was uncomfortable.

In the present invention was made to solve the above problems, the problem of the present invention is to put out a hand to the nozzle to discharge the soap, accidentally plugging the nozzle outlet by hand, An object of the present invention is to provide a comfortable water soap discharge device that prevents the spray of water soap.

  According to the first aspect of the present invention, the water discharged from the nozzle in which the liquid passage is perforated toward the inside of the bowl of the handwasher by driving the pump by the human body detection signal from the human body detecting means and storing the water soap stored in the tank. The soap discharge device is characterized in that an escape hole for allowing the soap to escape is provided in the circumferential direction of the nozzle.

  As a result, even if a slight gap occurs when the discharge port is blocked by the palm of the hand, the soap is discharged from the gap in an unexpected direction and the clothes or face is ejected from the gap. Can be prevented.

  According to a second aspect of the present invention, the diameter of the escape hole is smaller than the diameter of the liquid passage.

  As a result, even if a slight gap occurs when the discharge port is blocked by a palm, the soap is discharged from the relief hole, so that the soap is spouted from the gap to cover clothes, the face, the outside of the bowl, etc. It is possible to prevent soiling, and by setting the diameter of the escape hole to be smaller than the diameter of the liquid passage, it is possible to reduce the amount of water soap leaking from the escape hole when normal soap is discharged. .

  According to a third aspect of the present invention, the relief hole is provided with a relief valve that opens at a constant pressure.

  As a result, even if a slight gap occurs when the discharge port is blocked by a palm, the soap is discharged from the relief hole, so that the soap is spouted from the gap to cover clothes, the face, the outside of the bowl, etc. It is possible to prevent soiling, and even if a slight gap occurs due to the discharge port being closed with a palm, the relief valve opens and water soap appears, so there is no spouting of water soap from the slight gap, Since the liquid passage is open during normal use, almost no pressure is applied to the relief valve provided in the escape hole, so that the soap can be prevented from leaking from the escape hole.

  According to a fourth aspect of the present invention, the escape hole is provided in an enlarged diameter portion provided at an outlet of the liquid passage of the nozzle.

  As a result, when the discharge port is not closed with the palm in normal use, the soap does not leak out from the escape hole during the discharge of the soap, and the soap is only released from the escape hole when the nozzle is closed. Therefore, there is little waste of soap.

  According to a fifth aspect of the present invention, a groove extending from the outlet of the escape hole to the rear end of the nozzle is provided.

  As a result, even if a slight gap occurs due to the discharge port being closed by a palm, water soap is discharged in a direction away from the discharge port toward the user by a groove extending backward from the escape hole. By doing so, it is possible to more effectively prevent the soap and soap from being blown out in an unexpected direction from the gap and soiling clothes and the face.

  According to a sixth aspect of the present invention, water discharged from a nozzle having a fluid passage is formed by driving a pump by a human body detection signal from a human body detection means and directing water soap stored in the tank into a bowl of a handwasher. The soap discharge device is characterized in that a protrusion that protrudes forward in the discharge direction from the discharge port of the nozzle is provided.

  As a result, even when trying to block the discharge port with the palm of the hand, a large gap is created between the discharge port and the hand due to the protrusion protruding forward from the discharge port of the nozzle, so that the water soap is scattered around the nozzle from the gap. Therefore, it does not spout toward the user's clothes and face.

  The seventh aspect of the present invention is characterized in that the protrusion is provided integrally with the nozzle.

  As a result, even when trying to block the discharge port with a palm, a large gap can be formed between the discharge port and the hand by the protrusion provided integrally with the nozzle protruding forward from the discharge port of the nozzle in the discharge direction. Since the soap is scattered from around the nozzle, it does not spout toward the user's clothes and face.

  According to an eighth aspect of the present invention, the protrusion is a rod-like body that is separated from the nozzle and penetrates the liquid passage of the nozzle.

  As a result, even if the discharge port is blocked, the rod-shaped body hits the palm of the hand, and a large gap is formed between the discharge port and the palm, so that the soap does not spout from the gap, and the rod-shaped body is separated from the nozzle. Since the conventional nozzle can be used as it is, it can be realized at low cost.

  According to a ninth aspect of the present invention, the protrusion is provided separately on the outer periphery of the nozzle.

As a result, even when trying to block the discharge port, the palm hits the side wall, and a large gap is created between the discharge port and the hand, so the soap is not ejected from the gap, and the side wall is separate from the nozzle. Since this nozzle can be used as it is, it can be realized at a low cost.

By constructing the nozzle part of the water soap discharge device as described above, even if a slight gap occurs due to the discharge port being blocked by the palm, water soap is discharged from the escape hole facing the inside of the bowl. Therefore, it is possible to prevent the soap from being blown out from the gap and soiling clothes, the face, the outside of the bowl, and the like.
