る。[Detailed description of the invention] (The following is the field of application of the invention, the prior art, etc. Purpose of the invention) The present invention relates to a heat exchange device for a bathtub. In the heat exchange section of a conventional bathtub, in order to reduce resistance to exhaust air, the distance between the heat-absorbing water walls is large, and the heat-absorbing water walls themselves are also large. For this reason, there was a drawback that the entire heat exchange section became large. The present invention uses a unique structure to make the heat exchange part itself smaller, thereby making the entire bathtub more compact. The details of the figure are as follows.

部９から流出する。(Hereinafter, the structure and operation of the invention) Reference numeral 1 denotes an endothermic water wall in which a large number of protrusions 2 are formed. The endothermic water wall heat exchange section 3 is constructed by narrowing the interval between the endothermic water walls 1. An exhaust fan 4 is provided on the upper part of the heat exchange section 3, and air circulation sections 5 are provided on both sides of the heat exchange section 3, and the exhaust fan 4 sucks in the exhaust gas and also sucks cooling air through the air circulation section 5. The configuration is such that it also performs the following. However,
When combustion starts in the burner 6, the endothermic water wall 1
Although a protrusion 2 is formed in and the intervals between the endothermic water walls 1 are narrow, the combustion exhaust gas passes between the endothermic water walls 1 due to the suction action of the exhaust fan 4. At the same time, the endothermic water wall 1 is heated well and is discharged from the exhaust section 7. When this happens, exhaust fan 4
Cooling air is simultaneously sucked from the air circulation part 5 by the suction action of the cooling air, and is discharged from the exhaust part 7 together with the combustion gas while cooling both sides of the endothermic water wall 1. Circulating water enters from the lower introduction section 8, is heated in the heat exchange section 3 consisting of a large number of endothermic water walls 1, and flows out from the upper outlet section 9.

る。(Purpose of the invention below) As described above, the present invention increases the heat transfer area by forming protrusions on the heat-absorbing water walls, and narrows the intervals between the heat-absorbing water walls, thereby increasing the number of heat-absorbing water walls. I can do it. As a result, the heat-absorbing ice wall itself can be made smaller, and the entire heat exchange section can be made smaller. Furthermore, by providing an exhaust fan in the heat exchange section, combustion exhaust gas is sucked in, and even though the space between each endothermic water wall is narrow, combustion can be stabilized and heating can be performed effectively. Both sides of the heat exchanger can be cooled by drawing cooling air, which has the advantage of extending the life of the heat exchanger.
