JP2000139744A - Nozzle for whirlpool bath - Google Patents

Abstract

PROBLEM TO BE SOLVED: To effectively prevent a part of the body of a bather from coming into contact with the front end of a nozzle or clogging it up by protruding an overhung part of a nozzle and/or an intake to a minimum necessary for biting a seal packing and equipping the tip at a position retracted from the inner peripheral face of the bathtub to the depth. SOLUTION: This nozzle for a whirlpool bath is equipped in a state that a sealing member 20 provided at the intake to be exposed in a bathtub 1 is attached so that it is protruded a little as much as the thickness of the packing 22 from the inside face of the bathtub, in order to seal a jet nozzle 21 attached to a nozzle 2 from the inside of the bathtub 1. The front end 21A is attached to the sealing member 20 at a position retracted from the inner peripheral face 1A to the depth. A strainer removing dust or the like in hot water is provided so as to be held by the sealing member and the front end thereof is disposed at the nearly same level with the inner peripheral face of the bathtub or at the same level with the front end face of the sealing member protruded a little.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a jet bath having a jetting system for jetting hot and cold water mixed with air bubbles into hot and cold water in a bathtub, and particularly to a jet bath having a suction port and / or a jet port. The present invention relates to a jet bath nozzle structure to be provided.

[0002]

2. Description of the Related Art In recent years, hot and cold water mixed with air bubbles has been jetted into a bath tub from a jet nozzle provided facing the bath tub, and the hot and cold water in the bath tub has been fluidized. Whirlpools have been developed and used which provide a warming, massage or relaxing effect.

This whirlpool is, for example, shown in FIGS.
As shown in FIG. 1, a circulation pump 100, a suction port 102 for sucking hot water from the bathtub 101, an air intake 103, an air mixing section 104, and a jet port 10 for jetting hot water mixed with air bubbles.
5. Piping 1 for connecting these parts and passing and circulating hot and cold water
06 and the like.

[0004]

Among these, the suction port and the ejection port are usually constituted by nozzles having a circular cross section. However, since the suction port and the ejection port protrude into the bathtub, these projections are formed. The body may come in contact with the part and become disturbing, and may cause discomfort such as pain. In particular, if the suction port is provided with a strainer for dust removal,
The protruding amount is even larger, and the above-mentioned problem occurs more remarkably.

[0005] Further, if the injection port is closed by the body, hot water may flow backward through the piping of the air mixing section, and if the suction port is closed by the body, the circulation pump may be broken. Effective countermeasures are desired.

[0006] In view of the above circumstances, the present invention provides a jet bath which can effectively prevent a part of a bather's body from contacting or blocking an outlet or an inlet in a bathtub. It is an object to provide a nozzle structure.

[0007]

That is, the invention according to claim 1 has an injection system comprising a pump, a hot water inlet, hot water and air outlets, and a circulation path connecting these members. In a whirlpool configured to inject hot and cold air mixed with hot and cold water in a bathtub,
An overhanging portion provided at the jet port and / or the suction port protrudes by a minimum height necessary for sandwiching a seal packing, and a jet nozzle provided at the jet port and / or the suction port. And / or the suction nozzle is provided at a position where the tip end is retreated to a position deeper than the inner peripheral surface of the bathtub.

[0008]

Preferred embodiments of the present invention will be described below with reference to the accompanying drawings. 1 and 2
1 shows a jet bath nozzle structure according to the present invention. In this jet bath nozzle, a sealing nozzle provided to face the inside of the bathtub 1 in order to seal the ejection nozzle 21 provided in the ejection port 2 from the inside of the bathtub 1. A stop member (constituting an overhang portion) 20 is provided so as to slightly protrude from the inner surface of the bathtub by the thickness of the packing 22. The sealing member 20 has a base end on the outer peripheral surface side (the outer peripheral surface 1B of the bathtub 1).
), And a lock nut 23 is screwed into this male screw portion. Note that reference numeral 24 in FIG. 1 indicates a spring.

In the jet bath nozzle according to this embodiment, the jet nozzle 21 is attached to the sealing member 20 such that the tip 21A of the jet nozzle 21 is located at a position deeper than the inner peripheral surface 1A of the bathtub 1. It is. In this embodiment,
Although the ejection portion has been described, the same configuration is also applied to the suction port, not limited to the ejection portion in particular, that is, a sealing member is provided, and the suction nozzle is similarly retracted to the back from the inner peripheral surface of the bathtub. It may be.

In addition to this embodiment, as shown in FIGS. 3 and 4, for example, the distal end side of the sealing member 20 'may be formed into a waveform in which peaks and valleys are alternately repeated. If
Even if a part of your body comes into contact with this during bathing,
It will not be blocked.

Next, another embodiment of the present invention will be described with reference to FIGS. In the jet bath nozzle according to this embodiment, a sealing member (forming an overhang portion) 3 provided so as to face the inside of the bathtub 1 to the suction port 3.
0 is provided so as to slightly protrude from the inner surface of the bathtub by the thickness of the packing 32. The sealing member 30
Is provided with a male screw on the outer peripheral surface side (near the outer peripheral surface 1B of the bathtub 1), and a lock nut 33 is screwed into the male screw portion.

Further, a bathtub 1 is provided in the suction port 3 of this embodiment.
Strainer 3 to remove trash mixed with hot water inside
1 is provided (removably) so as to be held by the sealing member 31, and the distal end portion 31 </ b> A of the strainer 31 is substantially at the same level as the inner peripheral surface 1 </ b> A of the bathtub 1 or the inner peripheral surface 1 </ b> A.
It is disposed at the same level position as the distal end surface of the sealing member 30 slightly protruding (the position may be slightly recessed from the inner peripheral surface of the bathtub).

[0013]

As described above, according to the present invention, the projecting portion provided at the ejection port and / or the suction port protrudes by the minimum height necessary for sandwiching the packing for sealing. In addition, since the ejection nozzle and / or the suction nozzle provided at the ejection port and / or the suction port is provided at a position where the tip end is recessed from the inner peripheral surface of the bathtub, a part of the body of the bather is provided. Can be effectively prevented from contacting or blocking the spout and suction port in the bathtub,
It is possible to provide a highly reliable pump that can prevent the backflow of hot and cold water in the pipe, and can prevent the failure and breakage of the pump.

Further, according to the present invention, since the nozzle portion does not protrude from the inner surface of the bathtub, it is possible to prevent a part of the bather's body from contacting and causing discomfort, thereby providing a comfortable jet bath.
