Description

[Detailed explanation of the idea] (Industrial application field) The present invention relates to a bathtub device.

(Prior Art) The present invention relates to a bathtub device. Conventionally,
In order to equalize the temperature of hot water in a bathtub, hot water is circulated using a pump.

(Problem to be Solved by the Invention) This conventional technology, as disclosed in, for example, Japanese Utility Model Application Publication No. 4845 of 1988, involves guiding hot water in the lower part of the bathtub directly to the heat exchanger using a circulation pump. It actively exchanges heat. Although the problem with such devices has been improved because all of the low-temperature hot water passes through the heat exchanger and is introduced into the upper part of the bathtub in a heated state, However, there was a temperature difference, which is still unsatisfactory.

(Means for Solving the Problems) In order to solve the above-mentioned problems, the present invention makes the front outer water wall of the endothermic water wall heat exchange section protrude in the lateral direction to form an extension part, and the extension part A hot water inlet and a hot water outlet connected to the bathtub are provided as openings, and a circulation pump is provided to connect the back of the outgoing path system of the endothermic water wall heat exchanger, the hot water outlet, and the extension. A forced convection path is formed by positionally communicating a jet flow from the circulation pipe so that it enters the hot water outlet part, and the outgoing path system and incoming path system of the heat exchange part and the extension part are configured to be in communication, It is characterized by a natural convection path.

(Function) A part of the hot water that enters the water absorption wall heat exchange section from the hot water introduction section is heated while passing through the outbound system and return system, and naturally convects through the heat exchange section. At this time, the other part of the circulating hot water that undergoes forced convection by the circulation pump passes only through the outgoing system and is ejected from the circulation pipe into the hot water outlet, and at that time, a part of the hot water that undergoes natural convection is sucked. While mixing, combine and lead to the bathtub. That is, the hot water is delivered to the bathtub while a portion of the naturally convected hot water is suctioned and mixed with the low temperature hot water that passes only through the outgoing system, so the hot water is low temperature. As a result, the hot water in the bathtub can be made uniform, and safe bathing can be achieved.

(Example) Reference numeral 1 denotes a water absorption wall heat exchange section, and 2 denotes a front outer water wall of the heat exchange section 1. The front outer water wall 2 projects laterally to form an extension 3. This configuration of the extension portion 3 allows the circulation pump 7 to be configured so that it does not get in the way. The extension part 3 is provided with a hot water inlet part 4 and a hot water outlet part 5 that are open and connected to a bathtub (not shown), and also has an outgoing back part 11 of the heat exchange part 1, the outlet part 5, and the hot water outlet part 5. The three extension parts are placed in communication so that the jet flow from the circulation pipe 6 equipped with the circulation pump 7 enters the hot water outlet part 5, thereby forming a forced convection path.
Further, the circulation pipe 6 is provided with a circulation pump 7, and the outgoing path system 8 and incoming path system 9 of the heat exchange section 1 and the extension section 3 are configured to communicate with each other to form a natural convection path.

Therefore, from the hot water introduction section 4 to the water absorption wall heat exchange section 1
A part of the hot water that has entered is heated while passing from the outgoing system 8 to the incoming system 9, and naturally convects in the heat exchange section 1. At this time, the other part of the circulating hot water that is forced to undergo forced convection by the circulation pump 7 passes only through the outward path system 8 and is spouted from the circulation pipe 6 to the hot water outlet section 5, while the other part of the hot water that undergoes natural convection is While suctioning,
Combine and mix and lead to the bathtub. That is, the hot water is delivered to the bathtub while a part of the naturally convected hot water is suctioned and mixed with the low temperature hot water that passes only through the outgoing system 8, so the hot water is low temperature. As a result, the hot water inside the bathtub is made more uniform,
Safe bathing can be achieved for the elderly, children, etc.

(Effects of the invention) As described above, this invention uses natural convection and forced circulation in combination, and the forced convection hot water only passes through the outgoing system of the heat exchanger, and while mixing them together, the low-temperature hot water This system is characterized in that it guides water into the bathtub and effectively equalizes the hot water in the bathtub.
