Description

[Detailed Description of the Invention] This invention relates to a bathtub that can reduce the temperature difference that occurs in the depth direction.

It is well known that when the water in a bathtub is heated by installing heat exchange pipes on the top and bottom of the bathtub wall that lead to the bathtub and pipes that return hot water heated to a high temperature in the bathtub to the bathtub, a difference in temperature occurs in the depth direction. In fact, countless attempts have been made in the past to reduce this temperature difference.

The problem was that the structure was complicated.

This idea is characterized by its simple structure and the ability to reduce the temperature difference in the water depth direction.The specific technical structure adopted to achieve this effect is based on the inner wall surface of the bathtub body. The main feature is that the heat pipe is installed in the depth direction of the water.

This invention will be explained below based on the drawings of the embodiments.

In the figure, 1 is the bathtub body. The bathtub body 1 may be made of stainless steel, enamel, or internal tile, and may be made of different types.

A recess 3 is provided in the inner wall surface 2 of the bathtub body 1, and a plurality of heat pipes 4 are fitted into the recess 3 in the water depth direction to form a bathtub 5.

The inner wall surface provided with this heat pipe 4 may be the entire circumferential surface or a portion thereof, but the effect of reducing the temperature difference is remarkable when the inner wall surface is provided with the entire circumferential surface.

Alternatively, the heat pipe 4 may be a so-called heat panel in which independent heat pipes are arranged side by side to form a panel, and this heat panel is of course included in the heat pipe 4.

In addition, to explain the structure of the heat pipe 4, as shown in FIG. 2, a metal mesh of the same type is placed on the inner peripheral surface of a tubular container 5 such as an aluminum pipe, stainless steel pipe, steel pipe, or various synthetic resin pipes with both ends closed. In addition to arranging a porous tube 6 such as the above, a condensable gas 7 such as methanol or ammonia which transforms within a practical range of water temperature is sealed in the tubular container.

The present invention is configured as described above, and the high-temperature water in the upper layer absorbs heat at the upper part of the heat pipe arranged in the water depth direction, and heat is radiated at the lower part of the heat pipe to warm the low-temperature water in the lower layer, so there is a temperature difference in the water depth direction. is reduced.
