Abstract

PROBLEM TO BE SOLVED: To shorten drying time in response to a temperature and humidity condition of air on the inside and outside of a bathroom by measuring air flowing in the bathroom and a temperature and humidity in the bathroom, and finding a substitutive value of a drying quantity by using its value as basic data. SOLUTION: A temperature T0 and humidity H0 of air flowing in a bathroom by ventilation and a temperature T1 and humidity H1 of air in the bathroom are measured by a sensor. A temperature T2 and humidity H2 in the bathroom at ventilating time are calculated as a function of a ventilating quantity Q from measured values of the temperature T0 and T1 and the humidity H0 and H1 on the inside and outside of the measured bathroom and an air space V per person of the bathroom. Wind speed (v) in the vicinity of clothes hung down in the bathroom is also measured, and a substititive value D of a drying quantity at ventilating time is found as a function of the ventilating quantity Q by (D=k.(Xi-Xg) (k represents a substance moving factor, and Xi and Xg represent absolute humidity in an air/clothes interface and the bathroom) from the calculated temperature T2 , the humidity H2 and the measured wind speed (v), and the ventilating quantity Q on which a substitutive value becomes maximum is found, and the ventilating quantity is adjusted by a ventilating means.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a method of drying clothes using a bathroom.

[0002]

2. Description of the Related Art Conventionally, a method of using a bathroom for drying clothes has been put to practical use. As a specific example of the clothes drying method using such a bathroom, for example, a method of circulating warm air in the bathroom is performed. However, this method has a drawback that it takes too much time until the clothes are dried because the humidity in the room increases with the drying of the clothes.

In order to remedy such drawbacks, a method is considered in which ventilation is performed while circulating warm air and drying is performed while constantly exhausting moisture. There was a problem that it was difficult to set the humidity conditions.

Further, for example, Japanese Patent Application Laid-Open No. 4-285597
In the official gazette, the temperature in the bathroom rises and exceeds the threshold,
And, when the humidity in the bathroom rises and exceeds the threshold, the ventilator is automatically activated, and when either the temperature or the humidity falls below the threshold, the ventilator is automatically stopped. A bathroom ventilation dryer has been proposed. The above-mentioned bathroom ventilation dryer aims at improving the efficiency of water discharge by ventilating after the absolute humidity has sufficiently risen, based on a rise in temperature and an increase in relative humidity.

However, the amount of drying is a non-linear function of temperature and humidity, and the determination of each threshold setting cannot balance the two so that the amount of drying is maximized. Therefore, the temperature and humidity controlled by the above-mentioned conventional technology do not satisfy the condition for maximizing the drying amount. In addition, since the temperature and humidity of the air flowing in from outside the bathroom during ventilation are not measured, the influence on the drying of the flowing air is not considered.

Therefore, in the above-mentioned prior art, it was not possible to control the amount of drying to be maximum, in other words, to minimize the drying time.

[0007]

SUMMARY OF THE INVENTION An object of the present invention is to provide a method of drying clothes using a bathroom, in which the drying time can be minimized by considering the temperature and humidity of the air inside and outside the bathroom. .

[0008]

SUMMARY OF THE INVENTION A clothes drying method using a bathroom according to the present invention comprises a circulating heating means for heating intake air from the bathroom and blowing it into the bathroom, and air outside the bathroom and air inside the bathroom. A drying method using a bathroom provided with a ventilating means for exchanging the temperature and humidity of the air in the bathroom when controlling the amount of ventilation so that the temperature and humidity in the bathroom are the optimal conditions for drying the clothing. The humidity, the temperature and humidity of the air flowing into the bathroom by the ventilation means, and the wind speed at the clothing installation position in the bathroom are measured, and the ventilation means corresponding to the ventilation amount is operated based on these measured values and the air volume in the bathroom. The temperature and humidity in the bathroom at the time are derived, and using the derived temperature and humidity in the bathroom and the measured wind speed, as conditions suitable for drying, the absolute humidity between the air / clothing interface and the bathroom is determined. Difference (a)
And the substitute value (D) of the dry amount defined by the product [(a) × (b)] of the mass transfer coefficient (b) between the air / cloth interface and the bathroom are given by the formula D = k · (Xi −Xg), and the ventilation is controlled so that the value is maximized.

In the above equation D = k · (Xi−Xg), k is the mass transfer coefficient [kg / m ² · h], Xi is the absolute humidity at the air / clothing interface [kg / kg], and Xg is the Absolute humidity [kg / kg] is shown.

[0010]

The clothes drying method using the bathroom according to the present invention measures the temperature and humidity of the air flowing into the bathroom and the temperature and humidity in the bathroom, and uses the measured values as basic data to substitute for the drying amount. Therefore, the drying time can be reduced in accordance with the temperature and humidity conditions of the air inside and outside the bathroom.
