(Example)
The inventor has analyzed each of the toilet heating apparatus according to the present embodiment and the toilet heating apparatus of the comparative example by simulation.

14 and 15 are schematic diagrams illustrating simulation results of the heating effect by the toilet heating device of the present embodiment and the comparative example.
Here, as a comparative example, one that blows warm air from the outlet 790 below the cabinet 600 shown in FIG. 10 was adopted. The room temperature of the toilet room 900 before the start of heating is 5 ° C., the temperature of the outlet 704 and the outlet 790 is 100 ° C., and how the 15 ° C. isothermal lines spread in the toilet room 900 after the start of heating is compared. .

  FIG. 14A shows the distribution of an isothermal line 750 of 15 ° C. 30 seconds after the warm air blowout when the toilet heating device of the present embodiment is used. Moreover, FIG.14 (b) represents distribution of the isothermal line 750 of 15 degreeC 30 second after warm air blowing when the toilet heating apparatus of a comparative example is used.

  14 (c), 14 (e), 15 (a), 15 (c), and 14 (e) are 90 seconds after the start of heating when the toilet heating device of the present embodiment is used. The distribution of the isotherm 750 at 15 ° C. after 1 second, 120 seconds, 150 seconds, and 240 seconds is shown. Similarly, FIGS. 14 (d), (f), 15 (b), (d), (f) are 90 seconds after 60 seconds from the start of heating when the toilet heating device of the comparative example is used. The distribution of the isotherm 750 at 15 ° C. after 120 seconds and after 240 seconds is shown.

  As a result of this temperature distribution analysis, in the case of the present embodiment, an isothermal line 750 of approximately 15 ° C. spreads to the diagonal corner of the toilet room 900 as viewed from the tray heating device after 60 seconds from the blowing of warm air, Further, after 90 seconds, it can be seen that the 15 ° C. isotherm 750 extends to the vicinity of the floor at the diagonal corner. That is, almost the entire toilet room 900 is evenly heated. After that, even after 120 seconds, 150 seconds, and 240 seconds, the entire toilet room 900 is maintained in a state of being wrapped with warm air.

  On the other hand, in the case of the comparative example, the warm air blown out from the outlet 790 immediately rises near the entrance of the toilet room 900 (on the side opposite to the toilet bowl), and warm air is not supplied around the toilet bowl 800. This tendency does not change even when 240 seconds elapse from the warm air blowing, and the 15 ° C. isotherm 750 is localized only in one corner of the toilet room 900. That is, the surroundings of the toilet bowl 800 are not efficiently heated, and heating is insufficient for a user who stands or sits in front of the toilet bowl 800.

  On the other hand, according to the present embodiment, not only around the toilet bowl 800 but also the diagonal corners of the toilet room 900 can be warmed up uniformly 60 seconds after the hot air blows out. As a result, the user who has entered the tray room 900 can be comfortably used by being wrapped in warm air near the entrance of the toilet room 900 or near the toilet 800.
