Abstract

PURPOSE:To enable legs and feet of a person sitting on a chair to be heated and an energy to be conserved by a method wherein a planar heater is arranged at a rear surface of a top plate of a table, a heat reflection plate opposing against the heater is installed at a rear surface of the top plate. CONSTITUTION:A table 1 is comprised of a top plate 2 and legs 3 arranged at a rear surface of the top plate. A heater member 4 made of a planar conductive high-molecular material is supported by supporting columns 5 at the rear surface of the top plate 2. In addition, a reflection plate 8 is installed at the rear surface of the top plate 2 in opposition to the heater element 4. When the heater element 4 of a heating device for the table 1 described above is energized, the heating element 4 may generate heat and heat the thighs of a person sitting on a chair. The heater element 4 has a characteristic of a positive coefficient of temperature, a resistance value is increased as a heating temperature is increased. An electric current is automatically limited, so that an automatic temperature control can be performed. Further, the heating element 4 enables a uniform heating of a large area, resulting in saving energy.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] This invention relates to a device for heating the space below a dining table.

[Conventional technology]

In recent years, as lifestyles have become more Western-style, buildings are starting to follow suit, and it has become more common for people to spend their lives sitting on chairs. Therefore, the traditional concept of a kitchen has been completely dispelled, and the dining kitchen has become established as a place for living. Namely.

It is well known that people prefer to have a dining table set up in the dining kitchen and eat while sitting on a chair.At the traditional dining table like the one above, the waist and feet of the person sitting on the chair are between the legs of the table. There is a problem in that people feel cold in their legs and feet during the winter because they enter the space of

This invention was made in order to solve the above problems, and provides a heating device for a dining table that can heat the legs and feet of a person sitting on a chair and can save energy. The purpose is to provide.

Another object of the present invention is to provide a heating device for a dining table that, in addition to the above object, can efficiently perform the heating and further save energy.

A heating device for a dining table according to the present invention is one in which a planar heating element is provided on the back side of a plywood board for one dining table.

In addition, in the heating device for a dining table according to another invention of the present invention, in the above-mentioned one, planar heating elements are provided at intervals on the back side of the plywood, and a heat reflecting plate facing the heating element is attached to the back side of the plywood. This is what I did.

[For production]

In this invention, a planar heating element is provided on the back side of the plywood, which heats the legs of a person sitting on a chair from above, and because a large area generates heat uniformly, the heating temperature can be set low. .

Further, in another aspect of the present invention, the heat generated by the two heating elements is reflected on the heat reflecting plate to warm the person, but does not heat the back surface of the dining table.

〔Example〕

1 and 2 are views showing one embodiment of the present invention, with FIG. 1 being a front view and FIG. 2 being a bottom view.

In the figure, (1) is the plywood (2) and the legs (
The dining table (4) is made up of plywood (2) with a support (
5) is a heating element made of a planar conductive polymer material supported by (6) is a lead wire drawn out from the heating element (4).

A power plug (7) is connected to the terminal. (8)
is a heat reflecting plate mounted on the back side of the plywood (2) facing the heating element (4).

In the dining table heating device configured as described above, when the heating element (4) is energized by connecting the power plug (7), 1
The heating element (4) generates heat and warms the thigh area of the person sitting on the chair. Heating element (4) has positive temperature coefficient (PTC)
The resistance value increases as the heat generation temperature rises, and the current is naturally limited, so it has the desirable performance of enabling self-temperature control. Moreover, since the heating element 9 is planar, it is possible to generate heat uniformly over a large area, and the heating temperature can be set low, resulting in energy savings. A linear heating element has a high heat generation temperature,
Moreover, since the temperature becomes non-uniform, energy saving cannot be achieved.

On the other hand, since the heat generated by the heating element 14) is reflected by the heat reflecting plate (8) to warm the person, this heating is performed with high efficiency. Furthermore, since heat is reflected downward and prevented from heating the 9 plywood (2), energy is further saved.

The heating element (4) is installed using the space under the dining table (1), and since it is planar, it can be placed in a narrow space.

〔Effect of the invention〕

As explained above, in this invention, a planar heating element is provided on the back side of the plywood of the two-diner table, so it has the effect of warming the legs and feet of the person sitting on the chair. Furthermore, the heat generation temperature can be set low due to the uniform heat generation over a large area, which has the effect of saving energy.

In addition, in another invention of this invention, two-sided heating elements are placed at intervals on the back side of the plywood, and a heat reflecting plate facing the heating element is attached to the back side of the two plywood sheets, so that the heat generated by the two heating elements is reflected by heat. It is possible to heat the nine people efficiently without heating the back side of the table by heating the people by reflection on the board, and there is an effect that it is possible to further save energy.
