Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a bath lid for use in a domestic bathtub, which is provided with a hot water opening/closing valve for a bath heater on the top surface.

[Technical background and conventional technology]

With the spread of central hot water supply systems, household bathtubs no longer need to have bath pots, so there are no restrictions on exhaust gas treatment, and they can now be installed in any location. Bathtubs that receive hot water from a central hot water heater have simple equipment, but on the other hand, they are inconvenient because the hot water cannot be reheated.

A solution to this inconvenience is a bathtub with a bath heater, which heats the bathtub by flowing hot water from a water heater through a heat exchanger attached to the bathtub.

In this bathtub with a bath heater, the hot water on/off valve that restricts the heat exchanger protrudes from the top of the bathtub.

On the other hand, instead of the traditional wooden bath lid,
Blow-molded synthetic resin materials have also become popular, and the bath lid developed by the applicant was first introduced in 1972.
Although such a lid has already been proposed in Publication No. 62289 and Publication No. 1678 of 1982, this lid could not be applied to a bathtub with a bath heater because the valve provided on the side of the bathtub would get in the way.

Furthermore, Japanese Utility Model Application No. 50-73651 discloses a technique in which a recess is provided through which a person's neck can be exposed in a sauna bath. However, with such known technology, it is only necessary to consider the relationship between the person already taking a bath and the bath lid, and the gap between the neck and the lid can be adjusted by the person taking a bath, so no problem arises.
In the case of a hot water on/off valve, the heat retention of the bath lid is a problem because it is used when the person is about to take a bath.

[Purpose of invention]

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a bath lid for a bathtub with a bath heater that can sufficiently keep a bathtub with a bath heater equipped with a hot water opening/closing valve warm and that can substantially close the top surface of the bathtub.

[Structure of the invention] According to the invention, there is provided a bathtub lid for a bathtub with a bath heater, in which a heat exchanger is attached to the bathtub and a hot water opening/closing valve is arranged on the top surface of the bathtub, which is created by blow molding a synthetic resin material. A center rib with a box-shaped cross section and a side rib are provided at the center and both sides of the top surface of the lid, and a rib with a chevron-shaped cross section is provided between the center rib and the side rib, and a hot water on/off valve is installed in a part of the side rib. A recess is formed around the recess to accommodate the hot water on/off valve, and a lower wall slightly larger than the outer diameter of the hot water on/off valve is formed around the recess, and a gap is formed above the lower wall to insert a finger between the hot water on/off valve and the upper wall. A wall is formed.

[Explanation of the effects of the invention]

Therefore, the hot water on/off valve installed at the edge of the bathtub is accommodated in the recess of the bath lid, so the upper part of the bathtub cannot be closed off with the bath lid, and the hot water on/off valve is closed by the lower wall around it. Since it is surrounded by the hot water valve, heat does not leak from around the hot water on/off valve, and heat retention is good. When operating the hot water on/off valve, a finger can be inserted between the top wall and the valve, so the bath lid does not have to be moved when operating the hot water on/off valve, resulting in good operability. In addition, since the blow-molded bath lid is hollow, it is reinforced with ribs, but the upper and lower walls also serve as reinforcement for the recessed area, so there is no strength problem and the recessed area is reinforced. No damage will occur.

〔Example〕

Embodiments of the present invention will be described below with reference to the drawings.

1 and 2 are a plan view and a front view showing the bath cover of the present invention applied to a bathtub with a bath heater, and a bath heater 2 is attached to the side of the bathtub 1. This bath heater 2 is equipped with a heat exchanger inside, and can reheat or reboil the hot water in the bathtub by circulating hot water supplied from a water heater to this bath heater. . Therefore, in order to restrict the introduction of hot water into the bath heater 2, a hot water opening/closing valve 3 is provided to protrude from the top surface of the bathtub 1.

On the other hand, the top of the bathtub 1 is covered with a bath lid to keep it warm except when bathing. This bath lid is usually 3
One to four lids of the same size are used to facilitate handling. However, in the case of bathtubs equipped with bath heaters, the hot water on/off valve protrudes above the bathtub, so with a normal lid, the sides would interfere with this valve, preventing the body from coming into close contact with the bathtub surface, making it impossible to Unable to keep warm.

Therefore, the bath lid 10 of the present invention is formed with a recess that engages with the hot water opening/closing valve 3. FIG. 3 is a top view of the bath lid 10, which is made by blow molding a synthetic resin material. Children may sometimes get on the bath lid, so it needs to be rigid to withstand this. Therefore, reinforcing ribs are provided on the lid, but in the bath lid 10 of the present invention,
As shown in FIG. 5, a box-shaped central rib 14 is formed in the center of the lid, and box-shaped ribs 13 are formed on both sides.
has been formed. The central rib 14 is formed in a box-shaped cross section with vertical side walls 14a, and between the side ribs 13 having a similar cross-sectional shape is a chevron-shaped rib 1.
2 is formed. Both side walls 1 of this chevron-shaped rib 12
2a forms an inclined surface.

On the other hand, a groove 11 facing the back side of the chevron-shaped rib 12 is formed on the back side of the lid 10 shown in FIG.
Also, pads 15 are attached to the four corners to be in contact with the top surface of the bathtub. Furthermore, a label 16 with the manufacturer's name and model is affixed to a suitable place on the back side. A recess 2 is formed at a predetermined location on the side rib 13.
0 is formed. The details of this depression 20 are in the 6th section.
As shown in FIGS. That is, the recess 20 is formed by molding the box-shaped side rib 13, and its peripheral wall surface is divided into two upper and lower stages. The lower wall surface 21 is designed to have a dimension slightly larger than the outer diameter of the hot water on-off valve 3 that engages with it to reduce leakage of steam and improve heat retention efficiency.

The upper wall 22 formed above the lower wall 21 has a large inner diameter so that the hot water on-off valve 3 can be freely operated with the lid closed. A gap is formed between them for your fingers to fit. The thickness between the side ribs 13 and the chevron-shaped ribs 12 formed on the top surface of the lid is reduced to reduce the overall weight. This surface 17 is low at the center and high at both ends 17a. The rear surface of the wall surface 21 of the recess is smoothly connected to this surface 17 via an inclined surface 24. Therefore, the formation of the recess 20 does not reduce the strength of the lid as a whole, and does not impair its aesthetic appearance.

〔summary〕

Since the bath lid of the present invention is constructed as described above, it fits tightly to the top surface of the bathtub equipped with a bath heater that has a hot water opening/closing valve that protrudes from the top surface of the bathtub, and not only ensures heat retention, but also allows you to freely use the bathtub with the lid on. The hot water on/off valve can be operated. The entire bath lid is made of synthetic resin by blow molding, making it highly durable and easy to handle.
