Abstract

PURPOSE:To comfortably take a bath irrespective of the winter season or the summer season by forming a head rest part for resting the head part in one side part of the upper end part of a bathtub main body, and adjusting a temperature of the head rest part to a desired temperature by a temperature adjusting means. CONSTITUTION:In one side part of the upper end part of a bathtub main body 1, a head rest part 2 for resting the head part is formed, and it is possible to take a bath while resting the head part, the neck and the shoulder part. In the lower part of the head rest part 2, a tank 4 is provided, the inside of the tank 4 is filled with a liquid heating medium, for instance, water, and an electric heater 5 and a thermocouple 6 are put in this heating medium. By a rotational operation of a temperature setting dial 7 provided on a flange F on the bathtub main body 1, the electric heater 5 is operated, and the heating medium is heated. Also, the thermocouple 6 detects a temperature of the heating medium, and its detecting signal is sent to a temperature control part 8. The heating medium is heated by the electric heater 5 until its temperature becomes a temperature set by the temperature setting dial 7. By heat conduction from the heating medium heated to the set temperature, the head rest part 2 is kept at the set temperature.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bathtub, and more particularly to a technique for comfortably basking in the winter or summer for bathing while resting with the head resting on the headrest portion during bathing. .

[0002]

2. Description of the Related Art Conventionally, a headrest portion provided at an upper end portion of a bathtub rests with the head resting when taking a bath.

[0003]

However, when taking such a bath, since the head is simply leaned against the head, when the temperature of the bathroom is low, such as in winter, the headrest portion is a side wall of the bathtub filled with hot water. When the bather rests his head, the temperature difference is so great that he cannot use the headrest to relax and take a bath.In addition, when the bath temperature is high in the summer, etc. The temperature of the headrest part was also high, and it was not possible to take a bath with the head resting while feeling a little cold.

The present invention is intended to solve such a problem, and an object of the present invention is to provide a bathtub in which the head rests on the headrest portion regardless of the winter season or the summer season to allow a comfortable bathing. It is in.

[0005]

According to the present invention, a headrest portion 2 for supporting the head is formed on one side of an upper end portion of a bath body 1, and a temperature for adjusting the temperature of the headrest portion 2 is provided on the headrest portion 2. It is characterized in that the adjusting means 3 is provided.

[0006]

The temperature adjusting means 3 adjusts the temperature of the headrest portion 2 to a desired temperature. In the winter, the user can comfortably take a bath while holding his or her head against the headrest 2 without feeling excessive coldness in the head and feeling an appropriate warmth. Also, in the summer, you can feel the appropriate coldness in your head and take a bath. In this way, you can enjoy a comfortable bath regardless of winter or summer.

1 (a) is a perspective view of a bath body 1 in which a headrest portion 2 for supporting the head is formed on one side of an upper end portion of the bath body 1, and the headrest portion 2 has a headrest portion 2. Department,
The neck and shoulders are supported so that you can take a bath. A tank 4 is arranged below the headrest portion 2,
The inside of the tank 4 is filled with a liquid heat medium (for example, water), the electric heater 5 and the thermocouple 6 are put into the heat medium of the tank 4, and the temperature setting dial is provided on the flange F of the bath body 1. 7 is provided, and the electric heater 5 is rotated through the temperature controller 8 and the thermocouple 6 by rotating the temperature setting dial 7.
Is controlled to control the temperature of the heat medium to a set temperature. FIG. 2 shows the flowchart. By rotating the temperature setting dial 7 provided on the flange F of the bath tub body 1, the electric heater 5 operates to heat the heat medium. The thermocouple 6 detects the temperature of the heat medium, and the detection signal from the thermocouple 6 is sent to the temperature control unit 8. Then, the heating medium is heated by the electric heater 5 until the temperature set by the temperature setting dial 7 is reached. In this way, the heat transfer from the heat medium heated to the set temperature causes the headrest 2
Is kept at the set temperature.

FIG. 3 shows another embodiment, in which a tank 4 is provided below the headrest portion 2, and the tank 4 is provided.
A pump 10 is connected to the tank via a pipe 9, and the bath water heated to an appropriate temperature by driving the pump 10 is supplied into the tank 4 via a check valve 11 to supply the headrest 2 with the bath water. The temperature can be appropriately raised by heat conduction from the inside. From the tank 4 of the headrest portion 2 to the inside of the bathtub body 1 through a pipe 32 having a two-way valve 12, the hot water stored in the tank 4 by opening the two-way valve 12 is transferred to the bathtub body 1. It is designed so that it can flow back down. In this way, by circulating the bath water between the tank 4 and the bath body 1, the headrest portion 2 is kept warm at an appropriate temperature.

In the embodiment of FIG. 3, the operation dial 13 is provided on the flange F of the bathtub body 1,
The opening / closing valve 15 provided in the water pipe 14 is opened by the operation of 3, so that the tap water from the water pipe 14 can be supplied to the tank 4 of the headrest portion 2 through the check valve 11a. is there. In conjunction with the opening operation of the opening / closing valve 15 of the operation dial 13 as shown in FIG.
The valve body 22 of the two-way valve 12 is operated via the shaft 24, the gear 25, the gear 26, the gear 27, and the valve shaft 23 (see FIG. 9), and the tap water in the tank 4 is transferred from the pipe 32 to the drain pipe 33.
It is designed so that the water can be drained to the outside of the bathtub main body 1 through the drainage. In this way, the headrest portion 2 is cooled by the tap water supplied to the tank 4, and the head is cooled in the summer so that the user can take a bath.

The open / close valve 15 of the operation dial 13
In conjunction with the closing operation of the shaft 24, the gear 25, the gear 26,
The valve body 2 of the two-way valve 12 via the gear 27 and the valve shaft 23.
2 is operated (see FIG. 8), the pipe 32 from the tank 4
Is connected to the return pipe 34 to the bath body 1 so that bath water can be circulated between the bath body 1 and the tank 4. Reference numeral 35 in the figure is a suction pipe. In this way, the opening / closing valve 15 is normally closed and the bath water is supplied to the tank 4 to heat and keep the headrest portion 2 warm. Reference numeral 16 in the figure denotes a switch for turning on the pump 10.

[0011]

As described above, according to the present invention, the headrest portion 2 for supporting the head is formed on one side of the upper end portion of the bathtub body 1, and the temperature for adjusting the temperature of the headrest portion 2 is formed on the headrest portion 2. Since the adjusting means 3 is provided, the temperature of the headrest portion 2 can be adjusted to a desired temperature by the temperature adjusting means 3, and an appropriate warmth can be felt without feeling excessive coldness in the head in winter. There is an advantage that the user can feel comfortable and can take a bath, and that he / she can feel the appropriate coldness in the head during the summer and can take a bath regardless of the winter or the summer.
