Description

[Detailed explanation of the idea] The present invention relates to a heating device.

A new heating device has been proposed in which the tabletop has legs with built-in heating elements, but this requires wiring from a single power cord to multiple heating elements. There is a problem in that it is difficult to remove the legs containing the heating element from the top plate.

This idea was created with these points in mind.
The purpose is to allow legs with built-in heating elements to be easily attached to and detached from the top plate of the table.

Next, one embodiment of the present invention will be described based on FIGS. 1 to 3.

A table 3 is formed by attaching leg parts 2 to the lower surface of the four corners of a top plate part 1. A flat table surface 4 is formed on the upper surface of the top plate section 1.

Further, each leg 2 is provided with a fan-shaped notch 5 whose horizontal cross section has an inner corner as its base, extending from a position slightly below the upper end of the leg 2 to a position slightly above the lower end. A heat insulating material 6 is provided along the inner surface of the notch 5, and a metal reflecting plate 7 is provided via the heat insulating material 6.

Further, an electric heating element 8 is provided inside the reflecting plate 7 from the upper end to the lower end of the reflecting plate 7,
Further, a guard 9 is provided inside the table 3 from the heating element 8 in accordance with the outer shape of the leg 2, and the guard a protects the heating element 8 to prevent danger.

Further, the top plate portion 1 of the table 3 includes an upper plate 11
A lower plate 12 is fitted and fixed to the lower side of the holder. Note that a wiring recess 13 is provided in advance on the upper surface of the lower plate 12, and a pair of outlet mounting grooves 14 are provided in each of the four corners of this wiring recess 13, and the lower surface around each outlet mounting groove 14 is provided. A square-shaped leg insertion groove 15 is provided in the hole, and a wiring cord 16 is routed to the wiring recess 13, and an outlet 17 connected to the tip of the wiring cord 16 is fitted into the outlet attachment groove 14. put. Therefore, by fitting and fixing the lower plate 12 to the upper plate 11, the wiring cord 16 and the outlet 1 can be connected to the inside of the top plate 1.
7 is built-in.

In addition, each of the internally wired cords 16 is connected to a power cord 21 which is pulled out from the top panel 1.
An intermediate switch 22 is provided in the middle of the power cord 21.

On the other hand, the top plate part 1 is attached to the outer peripheral part of the upper end of the leg part 2.
A square-shaped protrusion 23 is integrally formed to be inserted into the leg insertion groove 15, and a plug 24 is inserted into the outlet 17 from the center of the upper end of the leg 2.
are integrally installed. This plug 24 is connected to terminals at both ends of the heating element 8 using lead wires or the like wired inside the leg portion 2 .

Then, if the convex part 23 of the leg part 2 is inserted into the insertion groove 15 of the top plate part 1, and at the same time the plug 24 of this leg part 2 is inserted into the outlet 17 of the top plate part 1, The legs 2 can be attached to the top plate 1, and the heating element 8 incorporated in the legs 2 can be electrically connected to the power cord 21 via the wiring cord 16. Therefore, switch 2
2, the heating element 8 is energized to generate heat, and the space inside the table 3 and the space around the table 3 can be warmed by this heat. At this time, the heating elements 8 built into the four legs 2 radiate radiant heat evenly around them, but the reflecting plate 7, which is curved concavely toward the center of the table 3, prevents this from happening. The heat radiated to the reflecting plate 7 is reflected toward the inner space of the table 3, and the inner space of the table 3 can be effectively heated.

Further, in warm seasons such as summer, the heating element 8 is not activated and is used simply as a table.

The structure of this embodiment has the following advantages.

That is, after attaching the legs 2 to the top plate 1,
There is no need for wiring or connection, and assembly is easy. Furthermore, since the wiring is carried out inside the top plate part 1 and the leg parts 2, the aesthetic appearance is not impaired and the function as a table can be fully utilized.
Furthermore, although the heating element 8 is built-in, the legs 2 are detachable from the top plate 1, so the legs 2 can be removed from the top plate 1 to make it more compact when not in use or when being transported. can. Furthermore, the leg portions 2, which are detachable in this manner, can be easily replaced in the event that the heating element 8 breaks down.

Next, another embodiment of the present invention will be described based on FIG.

Four legs 2 are detachably attached to the four corners of a top plate 1 of a table. In other words, L is attached to the top plate portion 1.
A letter-shaped mounting bracket 31 is fixed, and a threaded part 32 of a bolt is provided protruding from the upper side of the leg 2, and the threaded part 32 of the bolt is inserted into the hole of the mounting bracket 31 and fixed with a nut 33. .

Further, a wiring cord 16 connected to a power source is wired and fixed to the lower surface of the top plate 1, and an outlet 17 at the tip of the wiring cord 16 is fixed at a position facing each leg 2 on the top plate 1. .

Each of the leg parts 2 is provided with a fan-shaped notch 5 as in the previous embodiment, and a metal reflective plate 7 is provided along the inner surface of the notch 5 with a gap 35 in between. An electric heating element 8 is provided inside the reflecting plate 7 from the upper end to the lower end of the reflecting plate 7, and a guard 9 is provided inside the table from the heating element 8 in accordance with the outer shape of the leg 2. This guard 9 protects the heating element 8 and prevents danger.

In addition, lead wires 36 are connected to terminals at both ends of the heating element 8.
This lead wire 36 is pulled out to the outside of the leg portion 2 through the gap 35, and this lead wire 36 is connected to the
A plug 24 is provided at the tip of the plug 24, and the plug 24 is connected to the outlet 17.

In the case of this modification, the wiring cord 16 and the connecting part between the top plate part 1 and the leg part 2 are exposed to the outside, and although the appearance may be slightly damaged, the top plate part 1 The legs 2 and 2 are removable, and are functionally equivalent to those of the previous embodiment.

Furthermore, the heating devices of the above embodiments are used as table-shaped electric stoves that have heating elements 8 on the legs 2, but if the table 3 is covered with a futon or the like, the heating elements 8 can be attached to the legs 2. It can also be used as a kotatsu.

Furthermore, it is not necessary to provide the heating elements 8 on all four legs 2; for example, two or three heating elements may be provided, and any plurality of the four heating elements 8 can be used by switching a switch. You may also do so.

Further, although the heating devices of the above embodiments are table-shaped, the legs 2 may be made long to accommodate a chair.

As described above, according to the present invention, the legs with built-in heating elements are removably attached to the top plate of the table, the cord connected to the power source is wired to the top plate, and the outlet of this cord is connected to the top plate. Since the plate part is provided at a position facing the leg part, and a plug to be connected to this outlet is provided on the leg part,
The legs with built-in heating elements can be easily attached and detached from the top plate mechanically and electrically, and there is no need to perform wiring or complicated connections after attaching the legs to the top plate.
Furthermore, the legs can be removed from the top plate to make it more compact when not in use or during transportation, and the legs can be replaced together if the heating element breaks down.
