Description

[Detailed description of the invention] The present invention relates to an indoor heating device, and its purpose is to radiate radiant heat from the back side of the heating element, which is composed of a plurality of planar heating elements, into the room, not only from the surface of the heating element but also from the back side. The purpose of the present invention is to provide a wall-mounted room heating device that can heat the room by effectively utilizing the radiant heat of the room, and is free from the risk of overheating or fire.

Next, an example of implementation of the present invention will be described based on the drawings.

In the figure, A indicates an indoor heating device, which includes a heating body 1' made up of a plurality of planar heating elements 1 whose end surfaces are in contact with each other, a reflecting plate 2 arranged in parallel with this heating body 1' with a gap 4 interposed therebetween,
It consists of a mounting frame 3 that connects a heating element 1' and a reflecting plate 2.

The planar heating element 1 has front and back substrates 1a, 1a, and a substrate 1.
and a resistance heating element 1b buried between a and 1a,
The substrate 1a is formed by adding a plasticizer, ie, an organic binder as a binder, to ceramic powder such as alumina, molding it into a thin plate shape using an extruder, and drying it.

The resistance heating element 1b is formed by screen printing a paste-like material prepared by adding an organic binder and a solvent to powder of a high melting point metal such as tungsten or molybdenum on the substrate 1a.

A sheet heating element 1 is formed in the shape of a sandwich arch by laminating and pressing another substrate 1a onto the substrate 1a on which the resistance heating element 1b is arranged in this manner.

The reflector plate 2 is formed by cutting a thin metal plate with an extremely small heat capacity, such as stainless steel or aluminum, which has excellent radiant heat reflection characteristics and has a length equivalent to the entire length of the mounting frame 3, which will be described later.

The mounting frame 3 has a vertical cross-sectional shape, and the planar heating element 1
Heating body 1' constructed by bringing a plurality of end faces into contact with each other
The length should be approximately the same.

In addition, the mounting frame 3 has screw holes 3c for connecting and fixing the individual planar heating elements 1 to the bent piece 3a at the front, and connecting and fixing to the indoor wall B via the reflector 2 and spacer 6 at the upright piece 3b at the rear. A screw hole 3c is opened.

The mounting frame 3 is placed opposite to the planar heating element 1 at the same height, and both are attached to the screw holes 3c of the front bent piece 3a through attachment means such as screws 5, bolts, nuts, etc. A large number of planar heating elements 1 are arranged and fixed in a linear manner adjacent to each other between the frames 3, 3, and one or several reflecting plates 2 are inserted into the screw holes of the upright piece 3b through spacers 6. The indoor heating device A is attached and fixed by inserting screws 5 into the holes 3c and fixing them to the indoor wall B.

At this time, the back side of the planar heating element 1 and the first reflective plate 2
A gap 4 corresponding to the width of the horizontal piece 3d of the mounting frame 3 minus the thickness of the planar heating element 1 is formed between the mounting frame 3 and the horizontal piece 3d.

The gaps 4 are provided at appropriate intervals over the entire length of the horizontal piece 3d of the mounting frame 3, or are otherwise communicated with the interior of the room through a continuous opening 7.

Note that both ends of the mounting frame 3 are covered with cover plates 8 to prevent the internal appearance of the lead wires 9 of the planar heating element 1 and their connecting fittings 10 from being disturbed by the appearance, and openings may be provided. 11 and is normally open.

In this way, the radiant heat from the back surface of the planar heating element 1 is reflected by the reflection plate 2 and prevents the indoor wall B from overheating, while the radiant heat enters the room through the opening 7 and the opening 11 of the mounting frame 3 cover plate 8. radiate effectively.

The upright pieces 3b of the mounting frame 3 are integrally bent at appropriate intervals over the entire length of the mounting frame 3, and the spacers 6 are interposed only between the reflecting plates 2 corresponding to the upright pieces 3b. Each reflector plate 2
It is also possible to adopt a structure in which the radiant heat transmitted between the spacers 6 is released into the room through the opening 7 through the opening 7, thereby further preventing the indoor wall B from overheating.

Next, an example of using the indoor heating device A of the present invention in which the sauna bath C surrounding wall 1c is used as the guide wall B will be described.

Sauna bath C has front, rear, floor, ceiling,
It is made up of panels 2c such as side panels, all of which are made of wood with a small heat capacity and are assembled and connected through an internal heat insulating layer.

The indoor heating device A is disposed at a desired position on the peripheral wall 1c of the sauna bath C and used. Normal sauna baths use a sauna stove with a sheathed heater, so the sauna stove occupies a large area, and because it uses natural convection, the head part is hot, but the foot part is cold, making it unsuitable for bathing. and
Peripheral wall 1 under or facing the indoor heating device of the present invention
When the heating body 1' is disposed at the position C, the temperature inside the sauna bath C can be maintained at a uniform temperature by effectively utilizing the radiant heat not only from the front surface of the heating body 1' but also from the back surface to heat the feet.

Incidentally, as shown in the figure, it is optional to arrange and use it on the seat 13, and the number of necessary sheet heating elements 1 to be used can be reduced by effectively utilizing the radiant heat from the back surface of the sheet heating element 1. It is inexpensive in terms of cost, and the space within the sauna bath C can be secured to the maximum extent.

As described above, the present invention constructs a heating element by bringing the end surfaces of a plurality of planar heating elements into contact with each other, supports this heating element with a mounting frame, and leaves a gap between the mounting frame and the back surface of the heating element. The reflector is secured and the reflector is attached, and this mounting frame is attached to the indoor wall, and a vent to the room communicating with the gap is opened in this mounting frame, so there are the following advantages.

The radiant heat from the back side of the heating element, which is made up of a plurality of planar heating elements, is reflected by the reflecting plate and radiated outside, that is, indoors, through the gap formed by the heating element and the reflecting plate, for effective use. It is possible.

Since the radiation from the back of the heating element is blocked by the reflective plate, it is not transmitted to the indoor walls, so there is no danger of overheating of the indoor walls or fire.

By installing the indoor heating device of this invention under the seat or at the lower part of the front wall or side wall of a sauna bath, it is possible to effectively heat the foot area. This eliminates the problem of the area being too cold and unsuitable for bathing, and maintains a uniform temperature in the room, allowing for comfortable bathing.

Since it is only surface-fixed to the indoor wall, it does not require the installation space of a conventional sauna stove, and the room in which this indoor heating device is installed can be utilized to the maximum extent possible.

Thus, the intended purpose can be achieved.
