DESCRIPTION OF THE PREFERRED EMBODIMENTS The structure of the present invention will be described below with reference to the embodiments shown in the drawings. Note that the same reference numerals as those used in the related art are the same members. 1 to 3 relate to a first embodiment of the present invention, FIG. 1 is a schematic perspective view showing an entire drying apparatus of a bathroom 1, FIG. 2 is a longitudinal sectional perspective view of the same, and FIG. 3 is warm air. FIG. 3 is a partial vertical cross-sectional view showing a circulation system path in the bathroom 1 of FIG.

As shown in the figure, in this embodiment,
The ceiling panel 1C of the bathroom 1 is provided with an opening 7A for blowing air and an opening 7B for sucking air in the bathroom 1. Opposing wall surface 1 located below between both openings 7A and 7B
A laundry pipe 3 is attached across A and 1B. The openings 7A and 7B are provided in parallel with the laundry pipe 3 over the entire width of the bathroom 1.

Two fans 8A and 8B for blowing air and two heat exchangers 9A and 9B are provided above the opening 7A for blowing air. On the other hand, above the suction opening 7B, an exhaust fan 8C (see FIG. 1) for discharging the sucked air in the bathroom 1 to the outside of the bathroom 1 is provided.

Thus, in the bathroom drying apparatus of the first embodiment, from the entire area of the blowout opening 7A provided in parallel with the laundry pipe 3 over the entire width of the bathroom 1,
Uniform air is blown to the laundry hanging on the laundry pipe 3.

Further, due to the uniform suction from the suction opening 7B provided in parallel with the laundry pipe 3 over the entire width of the bathroom 1, the laundry pipe 3 is placed in the bathroom 1 as shown by arrows X and Y in FIG. Air circulation occurs so that it wraps all the clothes hung in it.

Moreover, the blowing speed of the warm air is 2 m / s or more, preferably in the range of 2 to 6 m / s. In this way, by performing drying at a wind speed of 2 m / s or more over the entire width of the bathroom 1, it is possible to perform remarkably efficient drying. The speed of the hot air blown out may be 2 m / s or more, but if it is set too high, the size of the motor will be increased and the motor noise will be increased, which is not preferable. It is important to set.

Further, in this embodiment, the temperature of the circulating hot water heated by the water heater 6 is set to 60 ° C. Conventional hot water temperature was 80 ° C. In this way, the temperature of the hot water could be lowered because of the above-mentioned outlet 7A for blowing.

Dehydration is carried out for 5 minutes, and the degree of dehydration (degree of dehydration (%) = mass of dry cloth (Kg) / weight of cloth after dehydration (Kg) × 100 (JIS
C 9606-1987)) was set to about 57% (in the dry test, a test body having a dehydration degree of (57 ± 0.5%) was used (JIS S 2098)).

[0029]

[Table 1]

The following is clear from the experimental data in Table 1 above. The experiments of No. 1 and No. 2 are different only in whether the subject bathroom dryer is according to the present invention or a conventional one, and the other experimental conditions are almost the same. Therefore, as in the case of the present invention, the gas consumption can be reduced by only 85% (470/550) only by forming the blowout opening over the entire width in the bathroom.

Experiments No. 3 and No. 4 are comparative examples in which the circulating air velocity of the bathroom dryer of A according to the present invention is about twice as high as that of the bathroom of B according to the conventional product. In this case, the gas consumption could be reduced to 73% (360/490).

Further, in the experiments of Nos. 5 and 6 and Nos. 7 and 8, the circulating wind speed of the bathroom dryer of A according to the present invention of Nos. 5 and 7 was compared with the bathroom drying of Nos. 6 and 8 of the conventional method. The temperature is about twice that of the apparatus and the temperature of the circulating water is set to 60 ° C. in the case of A according to the present invention of Nos. 5 and 7. By doing so, in the comparative example of No. 5 and No. 6, it is possible to reduce the gas consumption amount to 61% (360/590), and in the comparative example of No. 7 and No. 8, 58. It was possible to reduce the gas consumption by up to 80% (280/480).

In the experimental comparison example of No. 9 and No. 10, a retrofit louver was attached to the blowing opening of the conventional bathroom dryer of No. 10, and warm air was blown out in the entire width direction in the bathroom by the louver. It was done so. It became clear that gas consumption could be reduced to 76% at 260/340 by installing a retrofit louver and lowering the temperature of circulating hot water to 60 ° C.

Therefore, if the temperature of the circulating hot water is set to 60 ° C. and the technique of attaching the retrofitting louver of No. 10 and the technique of doubling the circulating wind speed of the blowout opening of No. 3 are approximately doubled as compared with the conventional technique, Due to the synergistic effect, it is possible to significantly reduce gas consumption. Calculated as 0.85
× 0.76 = 0.65, which is a 35% reduction in gas consumption.

By the way, the present invention is not limited to the above-mentioned embodiment, and for example, the water heater may use petroleum as a heat source. If the louver blows out warm air in the full width direction of the bathroom, the louver may be attached to the outlet of the existing bathroom dryer by retrofitting. A bathroom dryer incorporating the louver is used in advance. You may do it.

[0036]

As described above, in the hot water heater type bathroom drying apparatus of the present invention, the hot air blowing opening is set to substantially the entire width of the bathroom so that the hot air spreads in the entire width direction in the bathroom. Alternatively, a louver is provided at the hot air blowing opening so that the hot air blows out in the full width direction of the bathroom, and the warm air blowing speed is 2 to 4 m / s or more. The temperature of the circulating hot water is set to 60 ° C.

That is, the wind velocity of the hot air blown out is 2 m /
The temperature of the circulating water as the heat source of the heat exchanger is 60 or more because it is s
It is possible to dry an article to be dried such as a laundry in a short time even at ℃.

Therefore, it suffices to heat the warm water to 60 ° C., and it is possible to reduce the energy consumption of gas or petroleum, etc. by that amount, as compared with the conventional heating to 80 ° C.
