Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a hot air generating device that utilizes solar heat.

(Prior Art) There have conventionally been many devices that use a pipe filled with water as a heat receiving part or fill a pipe tightly attached to a heat receiving plate with water and then heat the water using solar heat to produce hot water.

(Problems to be solved by the present invention) However, in such a device, the weight of water is added to the device, making it heavy and requiring a lot of work to install.Also, the structure is relatively complex, so it is not cheap. It had some drawbacks that made it difficult to provide.

In view of these drawbacks, the present invention seeks to provide a device that has a relatively simple structure and can be manufactured at low cost.

(Means for Solving the Problems) In order to achieve the above object, the present invention consists of an outer frame 1 consisting of a top wall, a bottom wall, and left and right side walls, a back cover 2, and a transparent plate 7 attached to the front surface. A solar heat receiving plate 5 made of black material and having numerous small holes perforated inside the box body.
is provided to form a heat receiving and insulating chamber 8, and a filter 6 is provided between the solar heat receiving plate 5 and the backing 2. A hot air suction conduit 4 is provided protrudingly, and a suction ventilation fan 3 is interposed at an appropriate location of the hot air suction conduit 4 on the outside of the box body, and air is drawn from the central lower part of the lining 2 to the outside of the box body. A suction conduit 9 is provided protrudingly.

(Function) Since the present invention is configured as described above, when the present invention is fixedly arranged so that the transmitting plate 7 faces toward the sun, the solar heat transmitted from the transmitting plate 7 hits the solar heat receiving plate 5, and the heat receiving plate 5 receives the heat. As the plate is heated, the temperature of the air within the heat receiving and insulating chamber 8 rises, and warm air is obtained within the heat receiving and insulating chamber. Next, when the suction ventilation fan 3 interposed in the hot air suction conduit 4 is operated, the warm air inside the heat receiving and insulating chamber 8 is released to the outside of the hot air suction conduit 4, and new air is introduced into the air suction conduit. 9 is inhaled. The air is sent to the heat receiving and insulating chamber 8 through countless small holes formed in the solar heat receiving plate 5 while removing dust and the like in the air by a filter 6.

Note that the hot air in the heat receiving and insulating room 8 always moves only in the direction of the hot air suction conduit 4 by operating the suction ventilation fan 3, so that the hot air passes through the small holes drilled in the solar heat receiving plate 5 and is sucked into the air. There is no back flow in the conduit 9 direction.

Since the present invention operates as described above, the warm air discharged from the hot air suction conduit 4 can be used for heating a room or the like. By the way, as a result of experimenting with the device according to the present invention in early January, when the solar heat receiving plate 5 receives heat with an area of approximately 0.6 m ² and is heated, the temperature of the warm air in the heat receiving and insulating chamber 8 is 50°C or higher. Even when the air was discharged outside the heat receiving and insulating chamber 8 using the ventilation fan 3, the temperature of the discharged air remained above 40°C. Therefore, it is known that the thermal efficiency can be further increased by expanding the area of the solar heat receiving plate 5.

(Embodiment) The present invention will be explained below based on the illustrated embodiment.The main body of the present invention is a box-like structure, and its appearance includes an outer frame 1 consisting of a top wall, a bottom wall, and left and right side walls, and a back part. The back cover 2 is made up of a transparent back cover 2 and a transparent plate 7 whose front surface is made of glass or the like through which solar heat can easily pass through.

Next, a solar heat receiving plate 5 is provided inside the box body, which is made of a black material so as to easily absorb solar heat, and has numerous small holes (not shown) to provide ventilation. A heat receiving and insulating chamber 8 is formed in the space between the plate 5 and the transmission plate 7, and a filter 6 is provided between the solar heat receiving plate 5 and the back cover 2 to filter out dust and the like in the air.

4 is a hot air suction conduit; the solar heat receiving plate 5;
The heat receiving and insulating chamber 8 is provided by protruding to the outside of the box through an appropriate location at the upper center of each of the filter 6 and the lining 2, and at an appropriate location of the hot air suction conduit 4 on the outside of the box. A suction ventilation fan 3 is interposed for discharging hot air from the hot air suction conduit.

Reference numeral 9 denotes an air suction conduit for sucking in fresh air, which is protruded from an appropriate location at the lower center of the lining 2 to the outside of the box body.

(Effects of the invention) Since the present invention is constructed as described above, it is relatively easy to obtain the warm air necessary for heating rooms, etc., and since it does not use water, it can be manufactured lightweight. Moreover, since the structure is relatively simple, the installation work is simple and there is an advantage that it can be provided at low cost.
