2. Description of the Related Art Recently, a bathroom with a drying function has been provided in which a drying mechanism is provided in the bathroom in order to improve the functionality of the bathroom and effectively utilize the space in the bathroom.

In a conventional bathroom with a drying function, as shown in FIG. 2, a laundry pipe 3 for hanging laundry or the like is provided above the bathtub 2 of the bathroom 1 with wall panels 1A, 1 of the bathroom 1.
The air blower 4 is attached between B and is provided on the back side of the ceiling panel 1C.

This blower 4 is provided with a fan 4A for blowing hot air, which is a sirocco fan, and a fan 4B for exhausting air in the bathroom 1, and has a front panel 5 with an opening 5A provided in a ceiling panel 1C. Hot air is blown out through the opening 5A and air in the bathroom 1 is sucked in. The air outside the bathroom 1 is heated by the heat exchanger 4 and blown into the bathroom 1. To the heat exchanger 4, the circulation line 6A of the water heater 6,
Hot water is circulated by 6B. The air in the bathroom 1 is exhausted through the exhaust fan 4B and the exhaust port 4D.

According to the air blower 4 as described above, the warm air blown into the bathroom 1 by the hot air blowing fan 4A circulates in the bathroom 1 as indicated by arrows A and B, and the laundry pipe 3 is provided therebetween. The laundry hung on is dried.

In the normal case, the area is 1600 mm × 1
In a 600 mm or 1200 mm x 1800 mm bathroom, the size (area) of the front panel 5 provided on the ceiling panel 1C is about 600 mm x 460 to 480 m.
The opening 5A provided in the front panel 5 has a size of 400 to 450 mm × 100 to 120 m.
It is about m.

[0007]

In the above-mentioned conventional bathroom with a drying function, the area ratio of the ventilation openings 5A is 16%.
Approximately 1/4 of the bathroom of 00 mm x 1600 mm, area 120
It is about 1/3 of 0 mm x 1800 mm bathroom, but about 1/2 of the opening 5A becomes the suction opening of the suction fan 4B, so the effective area as the hot air blowing opening is the opening 5
It is about 1/2 of the area of A.

Therefore, the effective width of the opening 5A as the blowing opening is extremely small for the long laundry pipe 3, and the warm air is only locally applied to the laundry hung on the laundry pipe 3. I can't hit it.

In the conventional bathroom with a drying function, in order to improve the drying efficiency, a relatively high temperature hot air of 40 to 60 ° C. is blown to raise the room temperature in the bathroom and lower the relative humidity. Although the laundry is dried, such drying with hot hot air damages the laundry made of heat-sensitive silk or wool. Drying causes the laundry to shrink significantly. High energy consumption and high gas or electricity costs. There is such a problem.

In the above embodiment, the entire amount of the air sucked from the suction opening 7B is discharged to the outside of the bathroom 1, but a part of the intake air is supplied to the suction side of the fans 8A and 8B. It may be returned to the inside.

The present invention will be described in more detail with reference to specific drying experiment examples.

Experimental Example 1 A laundry hanging rod installed in an environmental test chamber was provided with a weight of 110
17 pieces of 130-g short-sleeved T-shirts (total weight of about 2 kg) were hung and the time required for drying was examined.

The test body was washed in the standard mode of a fully automatic washing machine, dehydrated for 5 minutes, and the dehydration degree (dehydration degree (%) = mass of dry cloth (kg) / weight of dehydrated cloth (kg)). ) × 10
0 (JIS C 9606-1987)) was set to about 57% (in the drying test, a test body having a dehydration degree of (57 ± 0.5)% is used (JIS S 2093)).

The time required for drying is the moisture content ((mass of cloth after dehydration (kg) / time required for drying (kg)) instead of the degree of dehydration.
-1) x 100) was used to measure the time required for the water content to be 0% or less.

The environmental conditions used in the test are shown in Table 1.

[0026]

[Table 1]

With respect to the above conditions, the method of blowing air was changed as follows, and the time required for drying was examined, and the results are shown in Tables 2-5.

I No wind The time required for drying all 17 sheets (IA) and the time required for drying only two sheets at both ends (IB) were examined. II When applying uneven and uneven winds: Make 5 of the 17 sheets in the center of the sheet hit with 2.0m / sec of wind, and set walls at both ends to give the same wind as a conventional bathroom with a drying function. It was carried out assuming that it would hit (average is 0.85 m / sec). III In the case of applying uniform wind with no bias The uniform load of 2.0 m / sec is applied to the entire 17 pieces of laundry, and walls are set up at both ends to make the conditions similar to the bathroom with a drying function of the present invention. did.

[Table 5]

The following are clear from Tables 2-5.

That is, it can be seen from the comparison between Tables 2 and 3 that those at both ends dry faster than the whole. The reason for this is that the laundry on both ends has no laundry at a position close to only one side, and one side is free (there is no humidity generation source), so the humidity generated from the laundry is quickly removed and drying is not possible. It is thought to be promoted. In addition, such a phenomenon was not observed in the blown air of II and III.

From the comparison between Table 4 and Table 5, the humidity 40
%, In order to complete the drying in 2 hours or less, the temperature is 20 ° C. or higher in the uniform blow of III, but 40 ° C. or higher in the non-uniform blow of II. According to the present invention, It can be seen that the temperature is lower by about 10 to 20 ° C. than the conventional one. Further, in the case of a humidity of 60%, in order to complete the drying in 2 hours or less, the temperature of 40 ° C or higher is required for the uniform blow of III, but about 60 ° C is required for the nonuniform blow of II, According to the present invention, it is possible to obtain the same drying rate at a temperature lower by about 20 ° C. than the conventional one.

Experimental Example 2 A comparative test was carried out to find the difference in energy consumption between the bathroom with a drying function of the present invention (Example) shown in FIG. 1 and the conventional bathroom with a drying function (Comparative Example) shown in FIG. .

The size of the bathroom unit is 1.2 m × 1.8.
The laundry pipe was horizontally attached at a position 0.3 m below the ceiling and 0.3 m below the ceiling. As the test body, the same one as in Experimental Example 1 was used, and as the water heater, No. 16 was used.
The outside air conditions on the test day were a temperature of 20 ° C. and a humidity of 60%.

As a comparative example, a hot water ventilation dryer (ABD-28KTEA) manufactured by Matsushita Electric Industrial Co., Ltd. (heat exchange capacity 260
0 kcal / hr), and as an example, two heat exchangers (radiator part) (heat exchange capacity 1300 kcal / hr) of a hot water ventilation dryer manufactured by Matsushita Electric Industrial Co., Ltd. were connected to a circulation blower. The capacity of the circulation fan is 390 in the comparative example.

The size was 0.05 m × 1.2 m, respectively. The results are shown in Table 6.

[0039]

[Table 6]

As is clear from Table 6, the bathroom with a drying function of the present invention can significantly reduce energy consumption and energy cost as compared with the conventional bathroom with a drying function. That is, for example, comparing gas, the cost is 24 yen (720 yen / month) in the embodiment, whereas it is 42 yen (1260 yen / month) in the comparative example, which is a saving of 6480 yen per year (however, , LPG 90
Calculated in yen / kg).

[0041]

As described in detail above, according to the bathroom with a drying function of the present invention, it is possible to uniformly blow air to the material to be dried hung on the laundry pipe and perform efficient drying. In the bathroom with a drying function of the present invention, since the moisture of the material to be dried can be quickly removed by uniform air blowing, the temperature is relatively low, for example, about 20 ° C. lower than the air blowing temperature in the conventional bathroom with a drying function. Since sufficient efficient drying can be performed even by blowing air at a temperature, the material to be dried is not deteriorated by heat, and the gas or power cost for drying can be significantly reduced.
