Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to a far-infrared radiant surface heater that is attached to a ceiling or wall.

<Prior Art> Heating appliances can be roughly divided into types that use oil or gas and types that use electricity.

Heating appliances that use oil and gas include oil stoves, oil fan heaters, gas stoves, and gas fan heaters. In addition, items that use electricity include electric stoves,
There is an electric kotatsu, ceramic heater, floor heating, air conditioner, etc.

<Problems to be Solved by the Invention> However, devices that utilize oil and gas have the problem of indoor air pollution due to CO2, CO, etc. generated during combustion.

On the other hand, those that use electricity do not have the problem of indoor air pollution, but they do have the following problems.

Although air conditioners have sufficient heating capacity, they have problems such as low air temperature, a feeling of chilly air due to the large amount of air being blown out, and slow start-up of heating.

In addition, electric carpets, which are a type of floor heating, are said to be an ideal heating device for those with cold heads and feet because they heat the entire floor by far-infrared radiation and heat conduction from the floor. Therefore, it is not possible to have a large radiant area, and it is difficult to achieve a sufficient heating effect. If the surface temperature is set high, the heating effect can be fully exerted, but there is a risk of burns and deformation of the floor, furniture, etc. due to the heat. Additionally, the type of heater installed inside the floor requires extensive construction work.

Generally speaking, underfloor heating has some problems, such as slow heating start-up and the need for a large amount of electricity.

Furthermore, the reality is that electric stoves, electric kotatsus, ceramic heaters, etc. are used for spot heating or auxiliary heating.

Next, with reference to FIG. 10, vertical temperature distributions of various heating appliances will be compared and examined.

Natural convection heating appliances, such as kerosene stoves,
Although there is no unpleasant feeling of airflow, the warm air concentrates on the ceiling of the room, and the area near the floor, which is the living space, does not get very warm. Also, the indoor temperature cannot be set.

Forced convection type heating appliances, such as oil fan heaters, which are the mainstream of current heating appliances, can obtain a more uniform temperature distribution than natural convection type heating appliances; Along with the high temperature, there is an unpleasant air flow.

Floor heating can warm only the floor surface without raising the entire room temperature, but it has the drawbacks mentioned above.

The present invention was devised in view of the above circumstances, and an object of the present invention is to provide a new heating appliance that eliminates all the problems that conventional heating appliances had.

<Means for Solving the Problems> The far-infrared radiant surface heater according to the present invention includes a planar radiant unit having an outer frame that radiates far-infrared rays when heated, and a heater section that heats the outer frame. , a controller that controls energization to the heater section,
The radiation unit can be attached to a ceiling or a wall.

<Operation> The heater section generates heat until the room temperature rises to the temperature set by the controller. Far-infrared rays of intensity are radiated from the outer frame depending on the temperature. This far-infrared ray not only warms the human body directly from the core, but also raises the room temperature by warming the floor, walls, furniture, etc. This synergistic effect provides heating.

<Example> Hereinafter, an example according to the present invention will be described with reference to the drawings.

FIG. 8 is a drawing of the heater section, in which (a) is a sectional view, (b) is a perspective view, FIG. 7 is an electrical circuit diagram of this far-infrared radiant surface heater, and FIG. 8 is a size of the radiant unit. Figure 9(a) is a graph showing the relationship between time and the surface temperature of the radiant unit, and Figure 9(b) is a graph showing the relationship between time and far-infrared radiation intensity on the floor. It is a graph showing a relationship.

The far-infrared radiant surface heater according to the present embodiment includes a planar radiant unit 10 having an outer frame 11 that radiates far-infrared rays 50 when heated, and a heater section 12 that heats the outer frame 11; The radiation unit 10 is equipped with a controller 20 that controls energization to the radiation unit 12.
is attached to the ceiling surface 40.

The radiation unit 10, which is attached to the ceiling surface 40 as a set of a plurality of units, includes a square tray-shaped outer frame 11, a heater section 12 housed in the outer frame 11, and a heater section 12.
It has a heat insulating material 13 that is laminated on the heat insulating material 13, a back cover 14 that presses the heat insulating material 13, and an overheat prevention device 15 that cuts off electricity when the radiation unit 10 is overheated.

A far-infrared radiating material such as ceramic is coated on a flat portion 111 (indicated by diagonal lines in FIG. 3(a)) of the outer frame 11. Therefore, when the outer frame 11 is heated, it radiates far-infrared rays 50 with an intensity corresponding to the temperature of the surface portion 111 (see FIGS. 9(a) and 9(b)). Further, a flange 112 for attaching the radiation unit 10 to the ceiling surface 40 is formed on the peripheral edge of the outer frame 11.

The heater section 12 is constructed by sandwiching a planar heating element 121 with polyester resins 122a and 122b, and has a shape and size that can be accommodated in the outer frame 11. In addition, the lower polyester resin 122a has
Adhesive material 123 for fixing heater section 12 to outer frame 11
is coated. In addition, in the drawing, 124 is the heating element 12
1 lead wire is shown.

The heat insulating material 13 is made of ceramic wool, glass wool, etc., and is laminated on the heater section 12.

The back cover 14 presses down the heat insulating material 13, and is set in shape and size so as to fit inside the outer frame 11. Further, the back cover 14 is provided with a connection terminal 141 to which the lead wire 124 is connected. By connecting this connection terminal 141 with a connection line 16, a plurality of radiation units O can be connected.

The overheat prevention device 5 is, for example, a thermal fuse or the like, and is installed on the upper surface of the heater section I2 so as to sensitively react to the temperature of the heater section 12.

A plurality of such radiation units O (16 in the drawing) are attached to the ceiling surface 40. At this time, the radiation units 10 are connected in parallel to each other via connection lines 16.

The controller 20 is installed between the radiation unit 10 and the power source, has a temperature sensor (not shown) that detects the room temperature, and controls the radiation unit 1 so that the room temperature reaches the set temperature.
This controls the energization to 0.

Note that although the controller 20 is fixed to the wall surface 41, a remote control method using infrared signals or the like may be used.

The radiation unit 10 is modularized.

Every building in our country has 1 room'. 1.8m is adopted as the basic unit. Therefore, the size of the room is 4.5 tatami = 2.7m x 2.7m = 1.5 tatami x 1.5 tatami, 6 tatami = 2
．． 7m x 3.6m = 1.5 rooms x 2 rooms, 8 tatami = 3.6m
The basic unit is 1 ken (3.6 m = 2 ken x 2 ken). Therefore, in order to efficiently install the radiation unit 10, it is sufficient to adopt 1 ken, that is, 1.8 m as a basic unit.

Therefore, the dimensions of the radiation unit 1o are: ■0. 9m
Q, 9m (hereinafter referred to as A type), ■0.6mX
0.6m (hereinafter referred to as B type), ■0.45m
X0.45m (hereinafter referred to as C type) is considered.

For A-type radiant unit lo, 4, 6, and 9 units are required for rooms of 4.5 tatami, 6 tatami, and 8 tatami, respectively (Fig. 8 (a), (d), ( g)). In addition, the B type has 9, 12, and 16 radiation unit O.
(See Figure 8 (b), (C), (5)), but in the case of type c, the radial unit 0 of the 16th, 24th, and 36th pieces is (
(See Figures 8(C), (f), and (i)).

Here, when considering manufacturability, workability, etc., type B is superior. In other words, type A requires fewer sheets to be installed, but is difficult to manufacture and handle, and has poor workability. Type C is easy to manufacture and handle, but it is inferior in workability because it requires a large number of installations. Type B has the advantages of both, that is, it is easy to manufacture and handle, and the number of installations is neither large nor small. Therefore, it is preferable that the radiation unit 10 is formed in a size of 0.6 m x 0.6 m. However, it goes without saying that the present invention is not limited to this size.

Next, the operation of the far-infrared radiation surface heater according to this embodiment will be explained.

so that the room temperature reaches the temperature set by the controller 20.
The heater section 12 generates heat. Then, far infrared rays 50 with an intensity corresponding to the temperature of the surface portion 111 are radiated from the outer frame 11. This far infrared ray 50 not only warms the human body directly from the core, but also raises the room temperature by warming the floor, walls, furniture, and the like. This synergistic effect provides heating.

When the heater section 12 is overheated, the overheat prevention device 15 stops the power supply to the heater section 12, thereby preventing disasters such as fire.

In addition, in the embodiment described above, the radiation unit 10 is attached to the ceiling surface 40, but it may be attached to the wall surface 4l.

Furthermore, in the above-described embodiment, the flat portion 111 of the outer frame 11 is coated with a far-infrared radiating material such as ceramic, but the outer frame 11 itself may be formed of ceramic, which is a far-infrared radiating material. The outer frame 11 may be subjected to far-infrared radiation alumite treatment or far-infrared radiation enamel treatment.

Effects of the Invention> The far-infrared radiant surface heater according to the present invention includes a planar radiant unit having an outer frame that radiates far-infrared rays when heated and a heater section that heats the outer frame, and the heater section. Since the radiation unit can be attached to a ceiling or a wall, the following effects can be achieved.

Far-infrared radiation can directly warm the body from the core.

Since no mechanically moving parts are used, no noise is generated.

Since no air is blown, there is no unpleasant feeling of airflow, and since no dust is kicked up, healthy heating can be achieved.

As shown in Figure 11, the power consumption of 1.2K is approximately 17"
Since I feel comfortable up to level C, I am able to perform heating that is more energy efficient than other heating devices that use electricity.

Since it can be installed on the ceiling or wall, you can make more use of your living space.

Next, other effects of the far-infrared radiant surface heater according to the present invention will be explained using graphs.

FIG. 10 is a graph showing the vertical temperature distribution of various heating appliances. Actual room temperature T1 by far infrared radiant surface heater,
Comparing the sensible temperature T2 measured with a glove thermometer, the sensible temperature T2 is 2 to 3°C lower than the actual room temperature T1.
It's getting expensive. This can be presumed to be due to far-infrared radiation. Note that a globe thermometer is used to measure temperature, radiation,
A thermometer that indicates the sensible temperature by integrating each element of airflow.

Also, the vertical temperature difference is smaller than other heating devices. In other words, the room is heated evenly.
