Description

  The present invention relates to a drain neutralizer for neutralizing drain generated in a latent heat recovery heat exchanger and a bathroom structure using the drain neutralizer.

  There are various types of bathroom structures. A typical example is a bathroom as shown in FIG. Such a bathroom 30 is a relatively old type bathroom, and a heating device such as a balance bath 50 is used for heating hot water in the bathtub 26, and a wall hole 22 formed in an outer wall 39 of the bathroom 30. In addition, a supply / exhaust tube 49 of the balance bath 50 is installed. (For example, refer to Patent Document 1).

  By the way, combustors such as bath pots and water heaters are replaced with new ones because their life is shorter than that of a house, and in recent years, more efficient equipped with a heat exchanger for recovering latent heat as a combustor. Increasing use of high combustion devices. When such a highly efficient combustion apparatus is applied, there is an advantage that environmental problems and energy problems can be alleviated. As is well known, the latent heat recovery heat exchanger is a heat exchanger that recovers the exhaust heat of the burner, and is provided in the case of the combustion apparatus together with the main heat exchanger that recovers the sensible heat of the burner. .

  FIG. 15 is an example of a bathroom structure when a hot water heater 17 with an automatic hot water filling function provided with a heat exchanger for recovering latent heat is applied as a combustion device instead of the balance bath pot 50 in FIG. The vessel 17 is installed in the wall hole 22 of the bathroom 30 instead of the air supply / exhaust tube 49.
