Abstract

PROBLEM TO BE SOLVED: To promote safely and efficiently convection, shorten heating time and resultantly save energy by supplying forcibly water to a heating section by the rotation of a propeller based on the restoring force of a power spring. SOLUTION: The device is mounted to a lower water conveyance opening of upper and lower circulation openings provided in a bathtub by suction disks 5, a winding up dial 4 is pulled, releasing from rotation conveyance with a propeller shaft, and rotated. At this time, a reversion prevention plate 8 comes into action and winds up a power spring 3. Water is supplied to a bathtub, and when the water is heated to an optimum temperature, by pushing the winding up dial 4, the propeller shaft and the winding up shaft 7 are linked, the restoring force of the power spring 3 rotates the propeller 2, produces a stream to a heating section, carrying out efficient heating, and shortens time required for heating to an optimum temperature. In the case of reheating, the appropriate rotation of the winding up dial 4 in the bathtub contributes to the improvement of reheating efficiency.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a circulating bath generally used in ordinary households, which is heated by natural convection, and forcibly convects bathtub water to quickly raise the temperature to an appropriate temperature. thing.

[0002]

2. Description of the Related Art Conventionally, heating has been performed by natural convection.

[0003]

(A) Conventional circulation baths are naturally circulating, and require a long period of combustion to an appropriate temperature, especially in winter, and are inefficient. (B) Debris easily adheres to the circulation pipe of the heating section and is unsanitary

[0004]

In order to shorten the convection time, the present invention is attached to the low-temperature water intake by the rotation of a propeller by the restoring force of the mainspring, and the water is forcibly sent to the heating section to promote the convection safely and efficiently. , Shorten heating time,
As a result, an energy saving effect is brought.

[0005]

Embodiments of the present invention will be described below. The present invention is attached to a lower water inlet of a circulation port having upper and lower portions in a bathtub with a suction cup 5, pulls a hoisting dial 4, releases rotation transmission with a propeller shaft 6, and turns a hoisting dial 4. Next, when the workspring spring 3 is wound up and water is supplied to the bath tub and the bathtub is adjusted to an appropriate amount, the winding dial 4 is pressed to connect the propeller shaft 6 and the winding shaft 7 to the shaft connection 10.
Is performed, the propeller 2 is rotated by the restoring force of the mainspring 3, and a water flow to the heating section is generated, so that efficient heating is performed and the time required to reach an appropriate temperature is reduced. In addition, when the additional cooking is performed, by turning it appropriately by the winding dial 4 in the bathtub, the efficiency of the additional cooking can be improved.

[0006]

This has the following effects. (B) Energy saving effect by shortening the heating time. (B) Reduction of scale, etc. attached to the heating section pipe. (C) Since there is no motorized part in the bathtub, electric shock and leakage accidents are eliminated.
