Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bathing method and a bathroom apparatus that can provide a bathing feeling without being immersed in a bathtub.

[0002]

2. Description of the Related Art As is well known, the basics of exhilaration by taking a bath are to immerse the skin in a bathtub and wet the skin with warm water to warm the whole body, and to remove dirt and other contaminants adhering to the skin of the body. The essential functions include wiping off sweat and the like to give a sense of cleanliness, and cooling a warm body lightly after taking a bath.

[0003] However, it is extremely difficult for elderly and sick people to enjoy the bathing feeling by immersing in a bath tub to wet the skin with warm water and warm the whole body.

[0004]

Therefore, in hospitals and accommodation facilities for the elderly, the sick and the elderly are immersed in a simple bathtub or wiped their bodies to taste the feeling of taking a bath. However, in such a case, the sick person or the like must be carried or held, and the body must be carefully washed.

[0005]

SUMMARY OF THE INVENTION Accordingly, the present invention provides a bathing sensation that is the same as that of a sick or elderly person who has a physical disability by simply entering a bathroom without a bathtub. Specifically, at least an intake path and an exhaust path are provided in the bathroom, air whose humidity and temperature are adjusted is supplied from the intake path, and air in the bathroom is discharged from the exhaust path. In the bathroom ventilation method described above, the target temperature and dew point in the bathroom and the ventilation amount that can be calculated based on the intake air amount are set in advance, and the temperature and relative humidity of the air that is sucked into the bathroom and the intake air that is the basis for calculating the ventilation amount The amount is detected and controlled by a temperature and humidity control mechanism provided in the intake path, so that the temperature inside the bathroom is 40 to 60 ° C, which is higher than the human body temperature, and the dew point is 35 to 45 ° C. Bath while maintaining control It relates ventilation method bath, characterized in that as the interior of the human bathing conditions.

Further, according to the present invention, an intake path and an exhaust path are connected to the bathroom, and the temperature and relative humidity of the air taken into the bathroom are detected in the intake path, and the intake air amount serving as the basis of the ventilation rate is detected. A temperature and humidity control mechanism is provided to supply while controlling the temperature, the temperature of the atmosphere and the dew point are detected inside the bathroom, and the temperature is 40 to 60 ° C. or higher than the body temperature of the human body, and the dew point is 35 to The present invention also provides a bathroom device characterized by being maintained and controlled at 45 ° C.

In general, when a person takes a bath, the person is naked, and in a cold place or the like, an abnormal cold is felt at the moment of entering the bathroom. This cold phenomenon is that the air in the bathroom is cold and heat is released from the whole body by convective heat transfer based on the contact of the air with the warm skin of the human body.
Because the floor, ceiling, etc. are cooled, the radiation of radiation generated due to the temperature difference from a warm human body, the radiation of moisture generated from the human body, such as sweat, evaporating from the skin to water vapor, the human body (for example, the instep) This is due to conduction heat dissipation due to contact between the air conditioner and a room surface (for example, a floor surface). These cold and cold phenomena can be solved by controlling the temperature and humidity of the air supplied to the bathroom to heat or adjust the atmosphere of the bathroom, and by heating the floors and walls. .

In the present invention, the heat radiating phenomenon from the human body in the bathroom is prevented, so that the cold phenomenon is suppressed and the feeling of bathing is enhanced. Further, according to the present invention, the dew point in the bathroom is made substantially the same as or somewhat higher than the body temperature, and condensed water is generated on the surface of the skin by condensation heat transfer with water vapor, thereby accelerating the heating and increasing the body core. Since the body temperature rises from the beginning and the same wet feeling as when immersed in warm water, the same effect as taking a bath occurs. Moreover, by setting the dew point higher than the body temperature, condensation heat transfer occurs in the respiratory organs of the human body, moistening the organs, and further accelerating the rise in body temperature.
A feeling of bathing similar to immersion in warm water can be given.

In the case of a sauna bath, the room temperature is as high as 110 ° C., but the relative humidity is extremely low at 1.5 to 2.5%, so that the dew point is about 10 to 25 ° C. Therefore, in the air atmosphere in a sauna bath, only sweating does not generate condensation water due to condensation and heat transfer to the human body.If condensation water is generated, the temperature of the human body and respiratory organs are burned due to the extremely high temperature. I do. Also, in a sauna bath, the heat received by the body is convective heat transfer by high-temperature air and radiant heat transfer from surrounding walls and the like, and the sense of heat reception to the human body is slowed down. Therefore, in a sauna bath, the body does not feel too hot at the beginning of entering the room, but after a few minutes, the body is heated extremely by the high temperature air and hot walls inside, so it is not suitable for bathing for the elderly or sick. Appropriate.

According to the present invention, the temperature of the bathroom is set to 40 to above the body temperature.
Adjust the temperature to about 60 ° C and set the dew point to 35-45.
By controlling the temperature to ° C., it is also possible to use dew water generated by condensation heat transfer with a high heat transfer rate. Therefore, instead of raising the temperature to an extreme high temperature like a sauna bath, by setting the dew point higher than the body temperature, the body's heat receiving sensation is extremely mild and sufficiently warm, and dew condensation on the skin surface The warm water adheres to the body and warms the whole body, so that a satisfactory bathing effect and refreshing feeling can be given to the bather.

In this case, the temperature of the bathroom air is set in the range of 40 to 60 ° C, and the dew point is set in the range of 35 to 45 ° C. Concerning the upper limit of the temperature, since the condensation heat transfer can be improved by raising the humidity to raise the dew point to a certain degree, it is not necessary to increase the temperature to 60 ° C. or higher in order to save the energy cost. Furthermore, if the dew point is 35 ° C. or less, much heat is not expected from the bather because condensation heat transfer on the skin surface of the bather cannot be expected much. Risk of burns and respiratory organs.

Inside the bathroom, at the time of bathing, the temperature and relative humidity of the intake air and the outside air, the temperature of the steam supplied to the bathroom, the detection of the amount of ventilation, etc. are constantly performed while calculating the saturated water vapor pressure of the outside air.
