Abstract

PURPOSE:To make it possible to supply a constant radiation energy all the time and provide a pleasant space heating by sensing the surface temperature of an object which is to be heated and diffusing or concentrating radiation heat by radiation energy density variation means so that the object is in a set range of temperature. CONSTITUTION:A heater 4 and reflection plates 5 are provided in a main body 3, and a sensor 7 is provided on the outside of the cover 6 of a heater 4. The reflection plates 5a-5e are constituted so that they are rotated in conjunction with linkage mechanisms 9. A control device 10 consists of a infrared ray temperature sensor 7, a comparator 11 and a motor control circuit 12. When a person 13 in the room is near to the main body 3 of a radiation space heater, and the infrared ray sensor 7 senses the surface temperature of the person 13, the reflection plates 5a-5e rotate outwards to diffuse the radiation energy. On the other hand when the person is distant from the heater, the radiation energy is concentrated by rotating the reflection plates inwards and supplied to the person 13. The radiation heat can be thereby controlled in a range of temperature in which the feeling of pleasant space heating can be obtained.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a radiant room device that performs heating using radiant heat from a heat source.

BACKGROUND OF THE INVENTION Conventional radiant heating devices of this kind generally have a configuration in which radiant heat from a radiant heat source 1 such as a heater or burner as shown in FIG. 7 acts on occupants in a room to provide a sense of warmth. 2 is a reflector plate that directs the 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 was not.

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 when the occupant is located near the radiant heat source, the heating capacity is lowered. Measures have been taken to provide a sense of warmth regardless of the distance between the indoor occupant and the heat source by operating at high heating capacity when the room is away from the heat source.

Problems to be Solved by the Invention However, with the above configuration for controlling radiant heating capacity, if the occupant is located near a radiant heat source and the capacity is lowered, it will not contribute to heating the entire room, and the room temperature will decrease. will go down. 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 higher than the heating load of the room, or in the case of electric heating, equipment with a higher capacity may be required due to the current capacity, luck, and cost. lacked practicality, and as a result had several problems, such as the inability to obtain a sense of warmth due to an absolute lack of ability.

The present invention solves these conventional problems, and provides a highly comfortable radiant heating system that maintains the heating capacity of the equipment constant and provides a stable sense of warmth regardless of the distance between the occupant and the equipment. The purpose is to

The only way to solve all the problems In order to achieve the above object fc, the present invention uses a radiant heat source.

radiant energy density variable means for changing the density of radiant energy from the @elbow heat source; surface temperature detection means for detecting the surface temperature of the object to be warmed; The system is equipped with a control device for controlling.

Function The present invention is directed to the above-mentioned Fi? This has the effect 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.

Embodiments Below, one embodiment 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, and shows the main body 3.
8 heaters as radiant heat sources 4. Reflector plate as means for varying the radiant energy density 5. An infrared temperature sensor 7 is provided outside the cover 6 of the heater 4 as a surface temperature detection means. FIG. 2 shows a cross-sectional view. A total of five reflecting plates 5a to 5e are configured to rotate in conjunction with a motor 8 and a link mechanism 9, as shown in FIG.

FIG. 4 is a block diagram of the control device 10, which includes an infrared temperature sensor 7 and a comparator 11 for comparing its output with a preset temperature. It further includes a motor sterilization circuit 12 that controls the motor 8 that rotates the reflectors 5a to 5e based on the comparison results.

The operation of the above configuration will be explained using FIG. 5 and FIG. 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 main body 3 is small, the reflectors 5a to 5e rotate outward and diffuse the radiant energy, thereby providing a comfortable heating feeling. 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 supplied to the occupant 13, and the surface temperature is adjusted to a comfortable level. Keep it within range. In either case, the heating capacity is kept constant, so no change in room temperature occurs. In this way, the resident 13 and the equipment body 3
Even if the distance from the occupant 13 changes, the radiant heat to the occupant 13 can be controlled within a range that provides a comfortable heating feeling without changing the heating capacity, so even if the occupant 13 moves around the room, the heating sensation will not be impaired. Never.

In addition, since the heating uses radiant heat, it provides the necessary warmth.

Although the heating capacity is lower than that of IIFIW cells, it also has an energy saving effect.Furthermore, it has excellent safety because the object to be heated will not be heated abnormally.

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

(1) Detect the surface temperature of an object to be heated, such as a resident, in front of the device, and use a radiant energy density variable means to adjust the surface temperature to a preset temperature range.
Because it diffuses or concentrates radiant heat, it
Even if the distance from the device changes, a constant amount of radiant energy can be supplied, allowing for comfortable heating.

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

(3) Since the surface temperature of the object to be heated is detected, there is no need to worry about abnormal heating, and safety is also compromised.
