Description

[Detailed Description of the Invention] The present invention relates to a structure for creating an average hot water temperature for a circulating bath in which an average value of the temperature of hot water can be obtained when controlling the temperature of a circulating bath.

When controlling the temperature of a circulating bath, it is difficult to detect the average value of the water temperature in the bathtub, as it is well known that the upper part is hotter and the lower part is colder. The method of controlling the temperature by using the same method does not allow accurate control and is accompanied by a waste of fuel consumption.

In order to eliminate the above-mentioned drawbacks, the present invention aims to provide a structure for creating an average hot water temperature for a circulating bath in which the hot water flowing through the outlet pipe has the average temperature of the hot water inside the bathtub.

An embodiment of the present invention will be described based on the drawings. Reference numeral 1 denotes a bathtub, and one side of the bathtub is provided with a recess 2 extending vertically from the inside to approximately the normal water level.

The cross-sectional shape of the recess 2 may be arbitrary, such as a semicircular arc shape or a U-shape.

Reference numeral 3 denotes a water outlet opened in this recess 2, which is connected to the bath pot 5 through a water outlet pipe 4.

6 is a batten attached to the front opening of the recess 2,
The batten has a large number of communicating lowers, and water in the bathtub 1 enters the recess 2 through these communicating lowers.

Note that the communicating lower portion may have any shape such as a round hole, a long hole, or a slit.

Therefore, the batten 6 may be formed into a perforated plate, a lattice plate, or an opening/closing lid having slits only around the periphery as shown.

Further, it is preferable that the battens 6 have a structure that is easy to clean.

The cross-sectional area should be equal to or greater than that of the communicating lower.

In the figure, 8 is a hinge of the batten 6, 9 is a tapping pipe, and 10 is a temperature detector.

In the present invention, since the structure is as described above, the water in the bathtub 1 is distributed through the communication lower part of the batten 6, the recess 2, the water outlet 3, and the water outlet pipe 4.
, the bath pot 5 and the hot water pipe 9 and then circulated back to the bathtub 1. In this case, the water in the bathtub 1 flows through a recess 2 vertically recessed on the side of the bathtub 1 to approximately the normal water level. The water enters the recess 2 through the communicating lower part of the batten 6 attached to the bathtub 1, collects and passes through the water outlet 3, and the amount of water passing through the communicating lower part is approximately equal to the length of the inside of the bathtub 1. Therefore, the temperature of this collected water indicates the average value of the hot water temperature inside the bathtub 1.

Therefore, by installing a suitable temperature detector 10 in the water outlet pipe 4, the average temperature in the bathtub 1 can be detected at all times, and the hot water temperature in the bathtub can be controlled accurately and efficiently. be.

As described above, according to the present invention, it is possible to collect approximately the same amount of water in the longitudinal section of the bathtub and guide it to the bathtub, so even if there is a large temperature difference between the upper and lower parts of the bathtub, the collected water can be represents the average temperature inside the bathtub,
This provides effects such as being able to accurately and efficiently control the temperature of the bathtub and preventing waste of fuel.
