Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a novel heating system and a photothermal conduction pipe using heat energy from a light source. The system of the present invention is particularly suitable for household, commercial or industrial ovens or other heating devices used for cooking food.

[0002]

2. Description of the Related Art There is a conventional heating device which uses a conducting wire such as a nichrome wire having a large electric resistance value and which is energized to generate heat.

Further, the oven generally used in the past is constructed by attaching an iron plate to the inner surface of a box body having a substantially closed space. Fuel such as gas is burned or heat is generated by an electric resistance action, and this heat is reflected by the inner surface of the iron plate and radiated to the food placed inside the box.

[0004]

In any of these conventional heating devices, it is necessary to provide a heat source or a heating body in or connected to the device. Heating elements are generally expensive and time consuming to replace.

Many lights and lamps are used in almost every house, office, factory, building and the like.
An electric lamp not only serves as a light source, but also generates heat energy during its operation. However, to the applicant's knowledge, no proposal has been made to use these light sources as the heat source of the heating device.

[0006]

SUMMARY OF THE INVENTION The present invention aims to provide a novel heating system which can eliminate the disadvantages encountered in the prior art, and more specifically, a light source such as a lighting fixture or sunlight. The proposal is to make effective use of the heat generated from.

That is, the present invention comprises a light source, heat collecting means for receiving radiant heat generated from the light source, and pipe means connected to the heat collecting means for transmitting the radiant heat to a heating point. Is a heating system.

Radiant heat can be dissipated or concentrated at the heating point, and control means for controlling this heat dissipating action can be provided.

As the light source, one or more bulb bulbs, sunlight, or the like can be used.

[0010]

The food or the like can be heated by effectively utilizing the radiant heat from the light source.

1 shows an example in which the technical idea of the present invention is applied to an oven. That is, this heating system is connected to a light source 1 such as a light bulb or sunlight, a funnel-shaped member 2 for collecting radiant heat of light energy generated from the heat source, and a converging side end of the funnel-shaped member. The pipe 3 for radiating radiant heat from the heat radiating port 4 into the substantially box-shaped oven 5 closed.

In the illustrated example, the pipe 3 is shown as a flexible pipe having a required length, but a plurality of pipes having a fixed length may be connected to each other. The inner surface of the pipe 3 is coated with metal, ceramics, glass or other material that reflects light well. The pipe 3 may be an optical fiber tube.

The heat dissipation port 4 of the oven 5 may be provided with means for concentrating or diffusing the heat dissipation effect in a specific area. That is, when a relatively large area is to be heated, the light heat supplied through the pipe 3 is diffused and radiated into the oven 5, and when the heating area is relatively small or a certain focus is to be heated, it is concentrated. Radiate heat to. By providing a control means for selectively controlling such a heat radiation effect, it is possible to meet a wide range of applications and requirements with a single oven.

A plurality of pairs of funnel-shaped heat collecting members 2 and pipes 3 can be used to increase the amount of light heat given to the heat dissipation port 5 of the oven 5. Each funnel member 2 receives the photothermal energy from the light source 1 and transfers it to the pipe 3 to which it is connected. The plurality of pipes meet at a point before the heat dissipation port 5. Alternatively, the oven 5 may be provided with a plurality of heat dissipation ports 5, and a plurality of pipes may be connected to different heat dissipation ports 5, respectively.

[0015]

According to the present invention, a novel heating system which is inexpensive and has a simple structure is provided. Since the heating device can be provided at a position distant from the light source, the configuration of the heating device itself can be simplified, or the heating device can be shared by a plurality of types of heating devices.

When a light bulb is used as the light source, it can be replaced when the bulb bulb is cut, and the replacement work can be performed easily and inexpensively. When sunlight is used as the light source, the resource is extremely limited.
