Abstract

PROBLEM TO BE SOLVED: To prevent dust from being produced owing to a cover and prevent time from being taken for a user to go in and out by providing a heating space with heat radiation between a cable top plate and a floor surface on which legs of the table top plate are placed. SOLUTION: With power supplied, a heater 5 on the upper side of a heat dissipation panel 3 produces heat to heat the heat radiation panel 3. Surface temperature of the heat dissipation panel 3 is set to be 80 to 150 deg.C, and the heat dissipation panel 3 radiates farinfrared rays downward therefrom to heat a heating space below a table top plate 1. An outer frame 4 is protruded lower than the heat dissipation panel 3 to prevent thereby the rise of a convection heat. The heat radiation panel 3 is flat plate-shaped, and a chair 8 is contained in the heating space below the heat dissipation panel. For heating action the heat dissipation panel 3 is raised in its temperature and long wavelength infrared rays are radiated and far infrared rays of about 7μm are radiated to heat a floor, chair 8 and a person. Therefore a thick bedquilt is not necessary and so dust does not occur.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a heating table for sitting on a chair and collecting heat.

[0002]

2. Description of the Related Art No conventional heating table achieves the same purpose as the present invention, but in the case of a similar chair type kotatsu, as disclosed in, for example, Japanese Utility Model Publication No. 52-157373. The configuration shown in FIG. 2 is generally known.

That is, in a chair type kotatsu, a heat source heater 9 located on the back surface of the table top plate 1 and arranged in the center thereof is used as a heat source, and a cover 10 such as cloth is used to prevent convective heat in the kotatsu from being released. 1, the heat source heater 9 was attached to the central portion in a concentrated manner, and the temperature of the heat source heater 9 of the heat source was high.

[0004]

In the above conventional structure, since the heat source heaters installed on the back side of the table top plate are concentrated in the central portion and the heat source heaters are high in temperature, unevenness in warming feeling occurs and a wide range is obtained. It is not warmed evenly, and there is a protrusion, and it is necessary to cover the outer circumference of the table top plate with a cover to suppress the escape of convection heat, so it is troublesome to use it such as dust coming out of the cover or taking time to come in and out. It was a thing.

[0005]

In order to solve the above problems, the following constitution means is adopted.

[0006] A table top plate having so-called legs installed, and a heat dissipation panel made of a flat and thin steel plate on the back surface of the table top plate, which is inside the outer shape of the table top plate and whose outer circumference is surrounded by an outer frame. Set the temperature of the heat dissipation panel at the time of operation to 80-150 ° C, and the side, which is mainly the lower side, has a surface coated with cloth or flocked fibers and is surrounded by the table top plate, the outer frame and the heat dissipation panel. In a heating table configured to provide a heat insulating material and a space layer in the dead space, a heating space by heat radiation is provided between the table top plate and the floor surface on which the legs of the table top plate are installed.

Further, the heat radiation panel is surrounded by an outer frame projecting downward from the heat radiation panel.

Further, the height from the top surface of the table top plate to the floor surface is set to 60 to 80 cm.

Further, a heating space is provided between the seat surface of the chair installed under the table top plate and the heat radiation panel.

[0010]

[Function] With the above configuration, 80 to 150 ° C
Far infrared rays are radiated downward from the heat radiation panel surface set to, and the effect of the far infrared rays efficiently warms the floor, knees, chairs, etc. without warming the air in the space.

Further, by disposing a heat dissipation panel made of a flat and thin steel plate in a wide area within the table frame, heat dissipation is uniform, the temperature of the heat dissipation panel can be raised with low power, and there is no protrusion, so that it is easy to use. It was

Further, since the outer frame projects below the heat dissipation panel, convective heat cannot escape.

The height of the heating table is 60 to 80 cm.
By doing so, you can sit on a chair and keep warm, and when you do not sit, the chair will also warm up.

Further, by providing the heat insulating material and the space layer in the space surrounded by the table top plate, the outer frame and the heat dissipation panel, it is possible to reduce the heat transfer to the upper surface of the table top plate.

[0015]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The construction of the present invention will be described below with reference to FIG.

Reference numeral 1 denotes a wooden table top plate having a flat upper surface, and a leg 2 composed of two legs or four legs is installed at a corner of the lower face.

Reference numeral 3 denotes a flat heat dissipation panel. The flat heat dissipation panel 3 is made of a thin steel plate, has a heater 5 on its upper side, and has a heater on its lower side. The surface is coated with cloth or flocked fibers, and this temperature is set to 80 to 150 ° C. in a normal state to serve also as a protective guard as an outer shell.

The heat radiating panel 3 is covered inside the outer shape of the table top plate 1, and the outer circumference thereof is covered with an outer frame 4 projecting downward from the heat radiating panel 3.

The heat insulating material 6 and the space layer 7 are provided in a space surrounded by the heat dissipation panel 3, the table top plate 1 and the outer frame 4.

The chair 8 has such a height that the seating surface of the chair 8 can enter below the heat dissipation panel 3, and the main heating table has a space in which the height of the table top 1 from the floor is 60 to 80 cm. Has become.

Next, the operation of the above configuration will be described.

With the above construction, when the power is turned on, the heater 5 on the upper side of the heat radiation panel 3 generates heat, and eventually the heat radiation panel 3 is warmed. At this time, the surface temperature of the heat dissipation panel 3 is set to 80 to 150 ° C., and far infrared rays are radiated downward from the heat dissipation panel 3 to warm the heating space under the table top plate 1.

By projecting the outer frame 4 downward from the heat radiation panel 3, rise of convection heat is prevented.

The heat dissipation panel 3 is flat, and the chair 8 is housed in the heating space below the heat dissipation panel.

As a heating action, the temperature of the heat dissipation panel 3 rises and infrared rays having a relatively long wavelength are radiated,
Far infrared rays of about 7 microns are mainly radiated to heat the floor in the heating space below, the chair 8 and the person collecting the heat.

[0026]

With the above structure, on the back surface of the top plate of the heating table in which the legs are installed on the table top plate,
A thin heat dissipation panel made of steel plate was used as a heat source to provide a flat heat dissipation panel with cloth or flocked fibers on the lower surface, so that the user tried to sit on a chair and warm up. In this case, there was no protrusion on the lower side of the back of the table top plate, which was easy to use.

Further, since the outer frame projects downward from the heat dissipation panel, convective heat is less likely to escape, the heat dissipation panel heats up with less power, and even if a foot or the like is put in from the lateral direction when collecting heat, the outside is first outside. Since it hits the frame, it can be used with confidence without directly hitting the high temperature heat dissipation panel.

Further, while the heat radiation panel can be set to a low temperature of 80 to 150 ° C., a large heat radiation area allows a large amount of far infrared rays having a heating effect to be radiated, and the entire lower surface of the table top plate. However, even if it is heated to a comfortable temperature and far infrared rays reach the peripheral part of the lower surface, it becomes possible for multiple people to warm up to the knees sitting close at the same time. It has become a heating device that can be warmed, comfortable and thoroughly warmed.

Further, by flocking the surface of the heat radiating panel and suppressing the surface temperature to 80 to 150 ° C., the heat radiating panel is directly exposed without hindering the heat radiating by installing other protective guards. The far infrared rays can be used efficiently.

Furthermore, since far-infrared rays do not heat the air in the middle and effectively heat the knees, legs, chairs and the entire floor surface, heating with less heat loss can be obtained. From this, hot air like a kotatsu futon is obtained. There is no need to enclose it, and there is no need for dust and the room to be narrowed when you hang a kotatsu futon, which gives you more comfort.
