Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a radiant heating device that performs heating using radiant heat from a heat generating source.

BACKGROUND TECHNOLOGY Conventional radiant heating devices of this type generally include a radiant heat source 1 such as a heater or burner as shown in FIG.
The structure is such that the radiant heat from the room acts on the occupants inside the room to give them a sense of warmth. 2 is a reflector plate for directing radiant heat toward the occupants. Radiant heating has the advantage that the perceived temperature rises quickly, but the density of radiant energy from equipment varies greatly depending on the distance between the radiant heat source and the occupants in the room. It had the disadvantage that it could not be used.

On the other hand, as shown in Japanese Patent Application Laid-open No. 58-179749, the radiant heating capacity is changed depending on the position of the occupant in the room, and if the occupant is located near the radiant heat source, the heating capacity is lowered. By operating at high heating capacity when away from the heat source,
Measures are taken to provide a sense of warmth regardless of the distance between the indoor occupant and the heat source.

Problems to be Solved by the Invention However, with the above-described configuration that controls the radiant heating capacity, if the occupant is located near the radiant heat source and the capacity is lowered, it will not contribute to heating the entire room, and the room temperature will decrease. becomes lower. In addition, combustion equipment has the disadvantage that it is difficult to reduce the amount of combustion to a predetermined capacity. On the other hand, if the occupant is far away from the equipment, it may be necessary to produce a capacity that exceeds the heating load of the room, and in the case of electric heating, equipment with a large capacity may not be practical due to current capacity and operating costs. As a result, they had several problems, such as being unable to sense warmth due to an absolute lack of ability.

The present invention solves such conventional problems,
To provide a highly comfortable radiant heating device that can provide a stable sense of warmth regardless of the distance between a resident and the device while keeping the heating capacity of the device constant.

Means for Solving the Problems In order to achieve the above object, the present invention includes a radiant heat source, a radiant energy density variable means for changing the density of radiant energy from the radiant heat source, and a surface temperature of an object to be heated. The apparatus is provided with a surface temperature detection means and a control device that controls the radiant energy density variable means based on the output of the surface temperature detection means.

Function The present invention has the above-described configuration, and has the function of detecting the surface temperature of an object to be heated, such as a resident, and diffusing or concentrating the radiant energy from the radiant heat source so that the temperature falls within the comfortable temperature range. has.

Embodiments Hereinafter, embodiments of the present invention will be described based on the accompanying drawings.

FIG. 1 is a front view of the radiant heating device of the present invention, with a heater 4 as a radiant heat source inside the main body 3, a reflector 5 as a radiant energy density variable means, and a surface temperature detection means on the outside of a cover 6 of the heater 4. An infrared temperature sensor 7 is provided. FIG. 2 shows a cross-sectional view. A total of five reflectors 5a to 5e are connected to a motor 8 and a link mechanism 9 as shown in FIG.
It is configured to rotate in conjunction with the
FIG. 4 is a block diagram of the control device 10, which includes an infrared temperature sensor 7, a comparator 11 that compares its output with a preset temperature, and a motor 8 that rotates the reflectors 5a to 5e based on the comparison results. It consists of a motor control circuit 12 that controls the motor.

The operation of the above configuration will be explained using FIGS. 5 and 6. FIG. 5 shows a case where the indoor occupant 13 is close to the radiant heating device main body 3. The infrared sensor 7 is detected when the occupant 13 is close to the radiant heating device main body 3. The infrared sensor 7 detects the surface temperature of the occupant 13. Since the distance between the occupant 13 and the device body 3 is small, the reflectors 5a to 5e rotate outward,
By diffusing radiant energy, a comfortable feeling of heating can be obtained. On the other hand, FIG. 6 shows a case where there is a distance, but here, by rotating the reflectors 5a to 5e inward, the radiant energy is concentrated and resident energy is supplied to the resident 13, and the surface temperature is reduced. Keep it within your comfort range. In either case, the heating capacity is kept constant, so no change in room temperature occurs. In this way, even if the distance between the occupant 13 and the device body 3 changes, the radiant heat to the occupant 13 can be controlled within a range that provides a comfortable feeling of heating without changing the heating capacity. Even if the heater moves, the feeling of heating will not be impaired.

Furthermore, since heating is performed using radiant heat, the required heating capacity is less than that of convection heating, and it also has an energy-saving effect. Furthermore, since the object to be heated will not be heated abnormally, it is also excellent in safety.

Effects of the Invention As described above, according to the radiant heating device of the present invention,
The following effects can be obtained.

(1) The surface temperature of an object to be heated, such as a resident, in front of the device is detected, and the radiant energy density variable means is used to diffuse or concentrate the radiant heat so that the temperature falls within a preset temperature range. Even if the distance between the heating object and the device changes, a constant amount of radiant energy can be supplied, allowing for comfortable heating.

(2) At this time, the heating capacity does not change, so the room temperature does not change and cause discomfort.

(3) Since it detects the surface temperature of the object being heated, there is no need to worry about it being overheated, making it highly safe.
