本考案は、鋳物ホウロウ引き浴槽に関し、ホウロウ焼成
時での浴槽の変形を軽減し得るものである。[Detailed Description of the Invention] The present invention relates to a cast enameled bathtub, and is capable of reducing deformation of the bathtub during enameling.
鋳物ホウロウ引き浴槽は浴槽基材を鋳造し、この浴槽基
材を電気炉等により赤熱し、これを電気炉等から取出し
て、浴槽基材の内面にホウロウを焼成することにより製
造されている。Cast enameled bathtubs are manufactured by casting a bathtub base material, heating the bathtub base material in an electric furnace or the like, taking it out of the electric furnace or the like, and firing enamel on the inner surface of the bathtub base material.
ところで、浴槽基材を赤熱する際、浴槽基材の浴槽側壁
の下端部が局部的に膨出することが往々にしである。By the way, when the bathtub base material is heated to red heat, the lower end of the bathtub side wall of the bathtub base material often bulges out locally.
この膨出は、浴槽自重のために生じるのであるが、浴槽
側壁の下端部が直線状であって、−個所が不測的に変形
され、以後、この巾変形個所が集中的に変形されていく
ことが膨出変形の主な原因で゛あると考えられる。This bulge occurs due to the bathtub's own weight, but since the lower end of the side wall of the bathtub is linear, the - area is unexpectedly deformed, and thereafter, this width deformation area is intensively deformed. This is thought to be the main cause of bulging deformation.
本考案は上記した、ホウロウ焼成時での浴槽下端部の局
的変膨出変形を防止すべく、種々検討したところ、浴槽
下端部を内側に彎曲させることが有効であることを見知
した。In the present invention, in order to prevent the above-mentioned localized bulging deformation of the bottom end of the bathtub during firing of the enamel, we have conducted various studies and found that it is effective to curve the bottom end of the bathtub inward.
これは浴槽下端部を彎曲させれば、荷重による浴槽下端
部の変形が彎曲部に分散され、上記浴槽下端部の局部的
変形が浴槽下端部の一様化変形に変態されて、変形が緩
和されるためであると考えられる。This is because if the bottom end of the bathtub is curved, the deformation of the bottom end of the bathtub due to the load will be dispersed to the curved part, and the local deformation of the bottom end of the bathtub will be transformed into uniform deformation of the bottom end of the bathtub, and the deformation will be alleviated. It is thought that this is because the
本考案に係る鋳物ホウロウ引き浴槽は、上記の検討結果
に基づき案出されたものであり、浴槽側壁の下半部が内
方向に彎曲され、浴槽上端の開口巾に対する底壁の巾が
０．９〜０．７とされていることを特徴とするものであ
る。The cast enameled bathtub according to the present invention was devised based on the above study results, and the lower half of the side wall of the bathtub is curved inward, and the width of the bottom wall relative to the opening width of the top end of the bathtub is 0. It is characterized by being 9 to 0.7.
第１図は本考案に係る鋳物ホウロウ引き浴槽の横断面を
、第２図は同浴槽の縦断面をそれぞれ示し、従来の浴槽
も点線で示されている。FIG. 1 shows a cross section of a cast enameled bathtub according to the present invention, and FIG. 2 shows a longitudinal section of the same bathtub, and a conventional bathtub is also shown by dotted lines.
本考案における浴槽の側壁１は従来の浴槽側壁１′が一
直線状であるのに対し、下半部はどの曲率半径の小なる
楕円弧状とされている。The side wall 1 of the bathtub according to the present invention has a straight line shape in the conventional bathtub side wall 1', whereas the lower half has an elliptical arc shape with a small radius of curvature.
すなわち、本考案浴槽の側壁は、上半部がほぼ垂直壁で
あり下半部が、内側に彎曲せる曲面壁とされている。That is, the upper half of the side wall of the bathtub of the present invention is a substantially vertical wall, and the lower half is a curved wall that is curved inward.
この側壁下半部の彎曲のためにホウロウ焼成時での側壁
下半部の変形は、既述した理由により充分に軽減され得
る。Due to the curvature of the lower half of the side wall, the deformation of the lower half of the side wall during firing of the enamel can be sufficiently reduced for the reasons described above.
また、本考案浴槽においては、上端の開口の巾に対し、
底壁の巾が０．９〜０．７とされている。In addition, in the bathtub of the present invention, the width of the opening at the top end is
The width of the bottom wall is 0.9 to 0.7.
このため、底部の面積が充分に広くされ浴槽容積が大で
ある。Therefore, the bottom area is sufficiently wide and the bathtub capacity is large.
これに対し、従来の鋳物ホウロウ引き浴槽の底壁の巾は
上端開口に対し、０．５〜０．６であり浴槽容積上から
も本考案浴槽に較べて劣っている。On the other hand, the width of the bottom wall of the conventional cast enameled bathtub is 0.5 to 0.6 times the width of the upper end opening, and it is inferior to the bathtub of the present invention in terms of bathtub volume.
その他、本考案の浴槽においては浴槽側壁の上半部が従
来の鋳物ホウロウ引き浴槽に較べて垂直面に近似し、浴
槽側壁に密接して内焚式のバランス釜を取付ける場合に
、バランス釜の取付けが容易である。In addition, in the bathtub of the present invention, the upper half of the bathtub side wall approximates a vertical surface compared to conventional cast enameled bathtubs, and when an internally fired balance pot is installed closely to the bathtub side wall, the balance pot Easy to install.
上述した通り、本考案に係る鋳物ホウロウ引き浴槽は、
従来の鋳物ホウロウ引き浴槽に較べてホウロウ焼成時で
の浴槽基体の変形を軽減できる、浴槽容積を大きくでき
る、バランス釜の取付けが容易である等の利点を有し、
有利である。As mentioned above, the cast enameled bathtub according to the present invention,
Compared to conventional cast enameled bathtubs, it has the advantages of reducing deformation of the bathtub base during enameling, increasing the bathtub volume, and making it easy to install a balance pot.
It's advantageous.
第１図は本考案の鋳物ホウロウ引き浴槽を示す横断面図
、第２図は同上浴槽の縦断面図である。FIG. 1 is a cross-sectional view showing the cast enameled bathtub of the present invention, and FIG. 2 is a vertical cross-sectional view of the same bathtub.
