Description

[Detailed explanation of the idea] The present invention relates to a natural circulation layer solar water heater.

As shown in Fig. 1, the natural circulation layer solar water heater 1 currently in general use has a separately manufactured hot water tank 3 above the heat collector 2, and the heat collector 2 and the hot water tank 3 are connected together.・They are interconnected with repeat circulation pipes to naturally circulate high-temperature water from the heat collector 2 to the hot water tank 3 and low-temperature water from the hot water tank 3 to the heat collector 2, allowing high-temperature water to be obtained in a short time. .

However, the hot water tank 3 of the natural circulation layer solar water heater 1 with the above configuration is tall and wide and has a large overall shape in order to store the maximum amount of hot water to be used, so the hot water tank 3 is higher than the roof surface. It had the disadvantage that it protruded significantly upwards and did not fit well with the roofs of modern buildings, spoiling the beauty of the building.

Furthermore, the natural circulation layer solar heat collector 1 consisting of the hot water storage tank 3 and the heat collector 2 has the disadvantage that a concentrated load of about 100 kg/rIl is applied to the roof when the water is full, which has a negative effect on the building.

The present invention was developed in view of the above-mentioned drawbacks, and it is possible to fix the heat collector on the south slope of the roof and install the hot water tank on the north slope without spoiling the beauty of the building when looking at the south slope. The purpose of this invention is to provide a natural circulation layer solar heat collector at a low cost that can distribute the load.

An embodiment of the present invention will be described below with reference to FIGS. 2 to 5.

On a gable roof having a south slope or a north slope, near the ridge 4 of the north slope, the roof has an oblong cubic shape, the bottom is shaped to match the slope of the roof, and a ball tap 5 is attached to the tip. The tank 8 is a hot water storage tank 8 in which a water supply pipe 6 and a hot water supply pipe 7 for supplying hot water to the kitchen, bathtub, etc. protrude inside.
The upper end portion protrudes upward from the ridge portion 4 and is fixed.

Then, on the south slope, a heat collector 9 equipped with a heat collecting pipe or the like inside is fixed with a wire or the like so that the upper end of the heat collector 9 is below the lower end of the hot water tank 8, and the heat collector 9 is connected to the hot water tank 8. In order to prevent the danger of air bubbles from the heat collector 9 accumulating at the highest position of the inflow and outflow pipes 10 and 11 of the ridge part 4 by connecting the heater 9 with the inflow pipe 10 and the outflow pipe 11 over the ridge. An air vent valve 12 is provided.

Further, the water supply through the water supply pipe 6 inside the hot water storage tank 8 is adjusted so that water is stopped by the ball tap 5 at a position above the highest position of the inflow pipe 10 and outflow pipe 11 of the ridge 4.

Therefore, due to the pressure difference between the highest water level of the inflow and outflow pipes 10 and 11 and the water stop position of the hot water storage tank 8, the low temperature water in the hot water storage tank 8 crosses the ridge 4 and reaches the heat collector 9. The warmed water rises, crosses the ridge 4, flows into the hot water tank 8, and repeats the circulation.

Therefore, in the present invention, the heat collector is installed on the south slope, the hot water tank is installed on the north slope, and the top of the hot water tank is installed so that it does not protrude too much from the ridge. In such cases, the visually appealing hot water tank is almost invisible, so it does not spoil the beauty of the building.

Furthermore, by installing one natural circulation solar water heater separately into a heat collector and a hot water storage tank, the concentrated load on the roof is dispersed and does not have a negative effect on the building.
