Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to an electric sauna bath used in general households, etc.0 Prior Art A conventional home sauna bath is shown in FIGS. 2 and 3. As shown, there is a wooden housing 1 into which a bather enters to take a bath, a heater 2 installed inside the housing 1 to heat the inside of the housing 1, and a heater 2 that detects the temperature inside the housing 1. The temperature detecting means 3 outputs an output when the temperature reaches a predetermined value, and the switching means 4 controls energization to the heating heater 2 based on the output of the temperature detecting means 3.In this way, the inside of the casing 1 is The temperature was adjusted to a predetermined temperature so that people could comfortably take a sauna bath.

Problems to be Solved by the Invention In such conventional electric sauna baths, the bather is
Even while taking a sauna bath inside, the heater 2 was controlled in order to maintain the temperature inside the housing 1 at a predetermined value. However, when controlling the temperature of the air, the speed of heat transfer from the heater to the air is generally slow, so the temperature of the air does not remain constant, but fluctuates up and down within a certain temperature range, and heater 2 is turned on ( !: Repeats OFF at regular intervals.

Therefore, in electric sauna baths used in general households, the distance between the bather and the heater 2 is short, and the distance between the bather and the heater 2 is short.
Since the bather receives radiant heat directly from
and "cold", two completely opposite stimuli.
Very unpleasant.

The present invention has been made in view of the above points, and an object of the present invention is to provide an electric sauna bath in which a bather does not have an unpleasant sensation by turning on and off a heater while taking a bath.

Means for Solving the Problems In order to solve the above-mentioned problems, the present invention provides a housing in which a bather enters to take a bath, a heating heater installed inside the housing, and a heater for heating the housing. an infrared detecting means that detects infrared rays emitted from the heater and outputs an output when it reaches a predetermined value; a temperature detecting means that detects the temperature inside the housing and outputs an output when it reaches a predetermined value; and a bath button that a bather presses when taking a bath. The configuration is such that the energization to the heating heater is controlled by a switch and a selection means that selects and outputs the outputs of the infrared ray detection means and the temperature detection means based on the output of the bathing switch.

Function: With this configuration, the heater is controlled so that the temperature inside the housing remains constant until the bather takes a bath, preheating the interior of the housing, and the bather operates the bathing switch. When taking a bath inside the housing, the heater is controlled so that the output of the infrared detection means installed inside the housing is constant in order to keep the radiant heat emitted from the heater to the bather constant. be done.

EXAMPLE Hereinafter, an example of the present invention will be described with reference to FIG.

3a is a temperature detection means, which includes a thermistor element 11 and a comparator 1.
The thermistor 11 converts the temperature inside the housing 1 into a voltage, and the comparator 12 compares the voltage with a predetermined value and outputs it. 6 is an infrared detection means, and an infrared sensor 13
The infrared sensor 13 is installed inside the housing 1, detects the infrared rays emitted from the heater 2, converts it into a voltage, and converts the voltage to the comparator 14.
is compared with a predetermined value and output.

The outputs of the infrared detecting means 6 and the temperature detecting means 3 are input to the selecting means 7, and one of them is selected by the bathing switch 6 operated by the user and output from the selecting means 7 to the switching means 4. Ru. The switching means 4a is composed of a relay 16, and when the selection means 7 outputs an output, the switching means 4a closes the contact 16a and energizes the heating heater 2.

With the above configuration, before the bather takes a bath, the selection means 7 is located at the terminal 7a and connected to the temperature detection means 3a, and the output of the temperature detection means 3a is output to the switching means 4. The heating heater 2 is controlled so that the temperature becomes a predetermined value. Then, when the bather presses the bath switch 6 to take a bath, the selection means 7 selects the terminal 7b.
and is connected to the infrared detecting means 6, and outputs the output of the infrared detecting means 6 which has detected the infrared rays from the heating heater 2 to the switching means 4, so that the infrared rays emitted by the heating heater 2 becomes a predetermined value. Do it like this. In other words, the interval between energization and deactivation of the heating heater 2 is shortened, the difference in temperature described in the conventional example is alleviated, and bathing can be made more comfortable.

Effects of the Invention As described above, according to the present invention, the user can preheat the inside of the housing to a predetermined temperature before taking a bath, and when entering the inside of the housing to take a bath, the user can use the radiant heat radiated by the heating heater. can be set to a predetermined value, so even if the housing is narrow and the distance between the bather and the heater is close, the heater can be turned on and off repeatedly as in the conventional case. , it gives the bather a sensation that is completely different from being cold and does not bother them, and it is possible to prevent discomfort and enjoy the sauna bath comfortably.
