Description

[Detailed description of the invention] (Technical field) The present invention relates to an electric heater.

(Background Art) Various types of electric heaters have been provided in the past, such as electric carpets, electric stoves, and electric kotatsu, but among these, the electric kotatsu is particularly Japanese and has been familiar for a long time. It is still widely used in households today.

However, in conventional electric kotatsu, an electric heating part such as an infrared lamp for electric heating is provided on the back side of the top plate and protrudes downward into the inside of the kotatsu, which limits the space inside the kotatsu. Because of the mouth, the electric heating part has the disadvantage that it is difficult to use when putting one's feet in the kotatsu or sleeping in the kotatsu.

In addition, conventional electric kotatsu have a single function as a kotatsu, making it difficult to use them as a multi-purpose heater.

(Object of the Invention) The present invention has been proposed in view of the above points, and its purpose is to provide a system that can be used for a variety of purposes, has sufficient internal space, is easy to use, and has excellent heating efficiency. The aim is to provide an electric heater that is easy to store, store, and transport.

(Disclosure of invention) The present invention will be described in detail below with reference to the drawings.

FIG. 1 shows an embodiment of an electric heater according to the present invention.

The upper part of the figure is the heater main body, and the heater main body 1 includes a substantially rectangular main body portion 1a disposed in the center and a bendable integral extension on each side of the main body portion 1a. These surface members are made of a material with good heat resistance, such as felt, and there is an electric heating means such as a sheet heating element of a known structure inside. The heating means is installed in one of the extension parts 1b.
It is connected to an external lead wire 2 that can be drawn out from the side of the base, and is connected to a commercial power source via the external lead wire 2, and heat is generated to the desired temperature by adjusting the temperature controller 3 with a well-known configuration. is configured to do so.

Further, A is a tower part, and this tower part I consists of a rectangular top plate 5, a frame part 6 made up of four fragments 6a on which this top plate 5 is provided, and four corners of this frame part 6. and leg portions 7 that can be connected to each other, and can be used together with the heater main body to form a kotatsu if necessary.

A coupling member 8 made of a circular magnet or a metal plate made of a magnetic material that is attracted by the magnet is provided on both outer sides of each bendable extension portion 1b of the heater body unit. . Correspondingly, each extending portion 1b is also provided on both sides of the outer side of each frame piece 6a of the frame portion 6.
A coupling member 8' such as a metal plate or a magnet is provided which can be coupled with the coupling member 8 provided on the holder.

Further, cutout portions 9 in which the lower ends of the leg portions 7 are located are formed on both inner sides of each extension portion 1b. The notches 9 are preferably formed to correspond to the shape of the legs 7, but each leg 7 may be placed on the four corners of the main body 1a without forming separate notches 9. You can also do it.

Next, the assembly procedure and usage method of the present invention will be explained.

When storing or transporting the heater body 1, the heater body 1 may be kept in a flat form as shown in FIG. It may be folded approximately 180 degrees.

In the tower section A, the top plate 5, frame piece 6a, leg section 7, etc. are usually separated and separated during storage and transportation.

Therefore, when the present invention is used as a normal kotatsu, when assembling the kotatsu, the cut grooves 7a formed in the upper part of each leg 7 are
Connecting portions 6b formed in a stepped manner at both ends of the frame pieces 6a are fitted within the frame pieces 6a, and each frame piece 6a and each leg portion 7 are integrated to constitute the main part of the tower, and the frame constructed in this way. A plate-shaped top plate 5 can be placed on top of the section 6.

Thus, the notch 9 of the heater main body 1 is opened into a flat plate shape.
The leg portions 7 are positioned inside, and each extension portion 1b is inserted as necessary.
A desired portion of the frame piece 6a is bent in a substantially vertical direction and brought into contact with the frame piece 6a. In this case, since the connecting members 8, 8' are provided on the extending portion 1b and the frame piece 6a, the two can be easily integrated. In addition, when bending the extension part 111, the part where a person enters the kotatsu is left open without the overlapping part C connected to the frame piece 6a.

Then, in this state, as shown in Fig. 2, a kotatsu can be obtained by placing a 4-ton 10 on top and placing a top plate 5 on top of it.

FIGS. 3(A) to 3(F) show the bent state of the extension portion 1b, and the arrows indicate the direction in which a person enters the kotatsu.

First, if a person enters the kotatsu from the right side or from the bottom as shown by the arrow in the illustrated state, (a).

(B) As shown in the figure, the extending portion 1b of that part is left open, and the other three extending portions 1b are bent approximately vertically and used by being combined with the frame piece 6a shown in FIG. Good. Also, when two people enter the kotatsu next to each other or facing each other, (
c), (d) It is sufficient to do as shown in the figure. Furthermore, in the case of three people, it is sufficient to do as shown in Figure (E), and in the case of four people, as shown in Figure (F), all the extension portions 1b may be in the expanded state.

After that, when the power is turned on and the controller 3 is adjusted, the main body 1a or each extension part 1b generates heat, and the desired warmth can be obtained. In this case, in the present invention, only the extension part 1b of the part where a person enters the kotatsu is left open, and the other parts of the tower part can be closed by bending the extension part 1b, so there is no heat escape and heating is possible.・Good heat retention. Therefore, there is an advantage that the inside of the kotatsu is warm even with a small amount of heating power.

In addition, the top of the heater body can also be used as a horigotatsu.
In this case, each extended portion 1b may be bent into a valve shape with an open top and housed in the recess of the horigotatsu.

Furthermore, the present invention can be used as an electric carpet, etc. By placing the heater body alone on the floor in the glabellar position as shown in FIG. It can be used as

Furthermore, as shown in FIGS. 3(A) to 3(E), any bent portion 1() is bent, and the bent state can be maintained by, for example, an L-shaped fixing auxiliary member (not shown). (Effects of the Invention) As described above, according to the present invention, the heater body has a rectangular shape. The main body is provided with bendable extensions on each side, and a heating means is built into the main body, the extensions, and the extensions, so that when used in the unfolded state, it can be used as an electric carpet. It can also be used as a panel heater by bending any extension part almost vertically, and it can also be used as an electric heater by placing it inside a kotatsu. It can be used for various purposes.

In addition, if the yagura part is built into the main body of the heater, it can be used as a regular kotatsu.In this case, there is no electric heating part such as an infrared lamp at the bottom of the top plate. This has the effect of being easy to use.

In addition, the extensions in areas where people cannot enter are bent almost vertically (thereby, no heat escapes, etc.), resulting in excellent heating efficiency and the ability to obtain good heating with less power consumption.

In addition, the heater body can be folded compactly.
Since the katsuyagura part can also be disassembled, it has the advantage of being excellent in storage and transportability.
