Specifically, a relay is provided in the indoor unit 12, and the fan 40 of the ventilation unit 14 is activated by the operation of the indoor unit 12.

  Next, a method for heating a toilet using the heating unit 10 and the ventilation unit 14 of the toilet heating structure 1 of the present invention will be described.

In order to start heating the toilet, first, the heating unit 10 is operated. Specifically, the heat source 30 is used to circulate the water in the circulation channel 53, and the blower 21 of the indoor unit 12 is operated. Here, the water (heat medium) in the circulation water channel 53 operates the pump 32 so as to maintain a preheated state so that rapid heating is possible, and the on-off valve 29 prevents the temperature of the radiator 20 from decreasing. It is circulated while controlling the combustion of the heat source 30 while opening and closing. Further, the operation of the blower 21 is performed when the user enters the toilet and uses the toilet. The input for operating the blower 21 may be input manually by the user of the toilet, or may be automatically input by detecting the user's entry.
When the indoor unit 12 is activated, the ventilation unit 14 is interlocked, and the fan 40 of the ventilation unit 14 is automatically activated.

When the toilet is heated, the heat generated by the heat source 30 moves as follows.
First, water inside the heat exchanger 31 is heated by heat generated by the heat source 30. And since the water in the circulating water path 53 circulates by the pump 32, this heated water flows into the outward piping 15a and reaches the radiator 20. Further, the heated water is radiated by the radiator 20 in the indoor unit 12. In addition, the water after having been radiated by the radiator 20 moves again to the heat exchanger 31 from the return pipe 15b.

  Since the blower 21 of the indoor unit 12 is operating, the air moves as indicated by the arrows in FIG. And the air in the toilet 5 enters the interior of the indoor unit 12 through the suction port 23 and passes through the gap 26. At this time, since the heat is radiated by the radiator 20, the air that has entered the interior passes through the gap 26. While passing, it is warmed and blown out from the air outlet 25 to raise the temperature of the air in the toilet 5.

On the other hand, when the indoor unit 12 is activated, the fan 40 of the ventilation unit 14 is interlocked and the air in the toilet 5 is discharged. That is, as shown in FIGS. 5 and 6, when the fan 40 operates, the air in the toilet 5 is discharged from the through hole 9. As shown by the solid line arrow in FIG. 5, the air in the toilet is discharged from the through hole 9 through the gap 8 between the wall 7 and the indoor unit 12.
When the air in the toilet 5 is discharged by the ventilation unit 14, the pressure in the toilet 5 is reduced, so that air flows in from the outside due to a gap in the door or the like.

  In the present embodiment, as shown in FIG. 5, the flow of exhaust in the toilet 5 caused by operating the ventilation unit 14 passes through the gap 8, and thus flows along the wall surface 7. Further, the flow of suction / blowout by the indoor unit 1 is a flow directed in the direction perpendicular to the wall portion 7. Therefore, the warm air blown out from the indoor unit 12 is blown toward the center of the toilet, so that the temperature in the vicinity of the user can be raised more quickly, and it is separated from the flow discharged outside the toilet. Therefore, it is difficult for warm air to be discharged.

  In the said embodiment, although the ventilation part 14 is constructed using the existing thing in a toilet, it may not be an existing thing and the new ventilation part 14 may be used. Moreover, although the indoor unit 12 and the ventilation part 14 were separate members, the ventilation part 14 can be provided in the indoor unit 12, and the indoor unit 12 and the ventilation part 14 can also be formed integrally. That is, when the ventilation unit 14 is provided on the wall 7 side of the indoor unit 12 and the fan 40 of the ventilation unit 14 is operated, the air in the toilet 5 may be discharged from the through hole 9 to the outside.

  In the above embodiment, water is used as the heat medium, but other heat medium can also be used.

  INDUSTRIAL APPLICABILITY The present invention can be used for a toilet structure that heats the inside of the toilet and reduces the scent of the toilet. Moreover, this toilet structure can be constructed using the existing ventilation unit 14 in the toilet.
