(57) [Summary] [Purpose] To provide a solar water heater capable of producing hot water with hot air. [Structure] The transparent plate 1 is provided on the upper surface of the box body 1 installed at an inclination.
a water tank 2 for heating is provided in the upper part of the box body, while a metal air flow pipe 3 is provided inwardly of the box body in the direction of inclination and a transparent pipe is provided in the flow pipe. 4 is externally fitted to form a double pipe structure, and the heated air guided by the flow pipe and the transparent pipe is brought into contact with the bottom of the water tank.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a hot-air type solar water heater that uses solar heat to produce hot water.

[0002]

[Prior Art]

 In general, solar water heaters use a transparent plate on the upper surface of a container that is installed at an angle, and heat the water in the container into hot water by introducing solar heat into the container through this transparent plate. It is designed to store warm water in the water tank above the container.

[0003]

[Problems to be solved by the device]

 An object of the present invention is to provide a hot-air type solar water heater that can produce hot water according to a principle different from the above-mentioned water heater.

[0004]

[Means for Solving the Problems]

 In order to achieve the above object, the present invention forms an upper surface of a box body that is installed at an inclination with a transparent plate, and provides a heating water tank on the upper part of the box body, A metal air flow pipe is installed in the direction and a transparent pipe is externally fitted to this flow pipe to form a double pipe structure. The heated air guided by these flow pipe and the transparent pipe rises. It is characterized in that it comes into contact with the bottom of the aquarium.

[0005]

[Action]

 The transparent plate that forms the upper surface of the box acts to take in solar heat into the box. On the other hand, the air flow pipe and the transparent pipe heat the air in the box by the solar heat thus taken in, and cause the air to circulate in the vertical direction. Therefore, the water in the water tank is heated by this circulating hot air.

EXAMPLE FIG. 1 is an explanatory view showing a part of the water heater according to the present invention as viewed from above, and FIG. 2 is a side view of the water heater as viewed from the side.

In the figure, reference numeral 1 is a box, and the upper surface thereof is a transparent plate 1a such as synthetic resin or glass. Reference numeral 2 denotes a heating water tank fixed to the upper part of the box body 1, which is provided with a water supply means 2a and a hot water take-out means 2b and a lid body 2c provided on the upper surface. Reference numeral 3 denotes a metal air flow tube which is fixed to the inside of the box body 1 in the vertical direction, and a transparent tube 4 made of synthetic resin or glass is externally fitted to the air flow tube to form a double tube structure. . Reference numeral 5 denotes a corrugated iron plate provided on the bottom of the box body 1, but the corrugated iron plate 5 may be the bottom surface of the box body 1. In the figure, numeral 6 is an intake hole, and numeral 7 is an outlet hole for the expanded air, so that a lid body which is automatically opened and closed when necessary is provided.

Next, a usage example and an operation of the product of the present invention having the above-mentioned configuration will be described. The box 1 is installed obliquely on a roof or the like, and the water w is poured into the water tank 2 from the water supply means 2a. When sunlight hits the upper surface of the box body 1, the solar heat is effectively taken into the box body 1 through the transparent plate 1a and heats the air between the transparent tube 4 and the distribution tube 3. At the same time, the outer surface of the flow pipe 3 is heated to heat the air inside thereof. The heated air is guided by these two pipes 3 and 4 and rises, moves to the upper part of the box body 1 and contacts the bottom part of the water tank 2 to heat the water w in the water tank 2. . As a result, this heated air is cooled at the bottom of the water tank 2, but the cooled air flows down along the bottom surface of the box body 1 and again inside the two pipes 3 and 4. It is heated by and reaches the bottom of the water tank 2 as described above. Therefore, the air in the box 1 continues to circulate while being heated, and the water in the water tank 2 is continuously heated. The hot water w thus heated in the water tank 2 is taken out from the hot water take-out means as required.

It should be noted that, when using the product of the present invention, when the air in the box 1 is heated, the air expands, but excess air is spontaneously discharged from the outlet hole 7 and is excessively discharged to the box 1. However, if the air inside the box 1 is cooled, the air contracts. However, in this case, the insufficient air is sucked from the intake holes 6 and excessive negative pressure is applied. Pressure does not act either.

[0010]

[Effect of the device]

 As described above, according to the present invention, it is possible to produce hot water by heating the water in the water tank with the hot air generated by the solar heat inside the box.
