JPH0632100Y2 - Locking device for movable diffuser for bubble bath - Google Patents

Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a jetting of jet water flow in a bubble bath which is designed to jet hot water circulated by a pump as a jet water flow containing bubbles in the bath. The present invention relates to a locking device for a movable diffuser that adjusts its orientation.

[Conventional technology]

In a bathtub equipped with this kind of bubble generator, a jet water flow containing bubbles ejected into the bath causes a systemic effect such as promoting the blood circulation of a bather by vibrating action of the bath water, and a body part to which this is applied. It is known to have an excellent local massage effect.

Therefore, there is a strong demand among bathers that the direction of the jet water flow from the jetting part attached to the side wall at the intermediate depth position of the bathtub can be adjusted so as to hit a desired portion.

Therefore, in the conventional device, as shown in FIG. 2, a diffuser a formed of a hollow tube having an outer peripheral surface formed into a spherical surface is provided with a packing b sandwiched between a support portion C and a holding ring d on the outer spherical surface. And is attached to the position facing the nozzle f facing the air chamber e so as to be able to swivel, or, as shown in the third illustration, the outer spherical surface of the diffuser a biased by a spring g is used as a non-slip resin for the support portion C. The diffuser was attached so as to be able to swivel by pressing it against the ring h.

[Problems to be solved by the device]

By the way, according to the diffuser locking means shown in FIG. 2 or 3 in the conventional apparatus, first, in the former case, the contact force of the packing b to the outside of the diffuser is largely changed by the tightening and tightening of the presser ring d. There is a change in ease of movement, resulting in lack of operational uniformity from product to product. Therefore, when installing a plurality of ejection parts in one bathtub, the non-uniformity of the products in each ejection part significantly impairs the merchantability.

Further, due to the elastic deterioration due to the aging of the packing b due to the use over time, the holding force against the diffuser a is weakened, and there is a possibility that the diffuser a cannot be held.

On the other hand, according to the latter, the spreading force of the spring g can prevent unevenness in the movement of the diffuser a and a decrease in holding due to a change over time, but on the other hand, it is erroneously used or mischief for children or the like. For example, when the diffuser a is strongly pressed against the acting force of the spring g by a part of the body, the diffuser a is separated from the non-slip resin ring h, and as a result, the airtightness of the air chamber e is impaired. , The negative pressure phenomenon of the chamber e due to the jet water flow does not occur,
Air bubbles cannot be generated because the air intake function cannot be fulfilled. Further, there is a defect that the diffuser a cannot be returned to the normal position due to damage of the spring or disengagement of the locking position.

Therefore, an object of the present invention is to solve the problems of the diffuser locking means by the conventional device as described above and to develop a device that can be constructed at low cost.

[Means for Solving the Problems]

In order to achieve this object, a locking device for a movable diffuser for a foam bath according to the present invention is provided in a bathtub with a bubble generator having a water inlet and a jet outlet of a hot water circulation pump in the bath. On the outer spherical surface of the diffuser placed at the jet outlet,
A pair of sandwiching plates made of resin curved surfaces whose abutting surfaces coincide with the outside spherical faces are opposed to each other, and the pair of sandwiching plates have a convex top portion of the outside spherical surface positioned approximately in the middle of the gap between the facings. The support is supported from both sides, and an elastic ring that does not come into contact with the outer spherical surface of the diffuser is interposed between at least one holding plate and the support.

[Action]

The diffuser sandwiched by the pair of sandwiching plates is supported and positioned by the contact sandwiching between the outer spherical surface and the sandwiching plate contact surface. Further, the diffuser can be held while being prevented from rotating by the anti-slip action of the holding plate contacting surface made of a resin surface and the holding plate pressing.

The elastic ring interposed between at least one holding plate and its support works on the contact surface with the diffuser by the holding plate pressing within the error of the assembly space absorbed by the elastic deformation. It has the function of keeping the contact pressure substantially constant.

In order to position the diffuser, when moving the diffuser in contact with the contact surface of the sandwich plate, the elastic ring does not contact the diffuser, and the elastic ring is not worn or damaged. The contact pressure exerted on the contact surface of the diffuser by elastic contact is kept constant.

The convex top of the outer spherical surface is located approximately in the middle of the gap between the pair of sandwiching plates facing each other, and the diffuser is pushed against the sandwiching holding force of the sandwiching plate to turn the diffuser toward the bathtub end. It can be adjusted smoothly in the desired direction. In that case, it can be adjusted with one operation in any direction and angle.

 Next, a preferred embodiment of the present invention will be described in detail.

FIG. 1 is a vertical side view showing an embodiment of the present invention. At the bottom position of the hollow portion in the jet body 1 shown in the figure, a connection port 2 of a pipe communicating with the discharge port of an external hot and cold water circulation pump is shown. Further, while the nozzle 3 connected to this is provided, an intake pipe 4 is connected to the hollow portion.

On the other hand, a nozzle housing 5 with an outer peripheral collar 5g is screwed into the wide mouth opening edge of the hollow portion, and the outer spherical surface is sandwiched by the pair of sandwiching plates 6 and 6 in the bottom plate central opening 5b of the housing 5. It is facing the diffuser 7 that was opened.
