Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a solar water heater in which the upper part of the collector part and the hot water storage part are connected and fixed, and the heat receiving tube storage case of the collector part is provided with a vent.

The above solar water heater is designed to prevent dew from adhering to the inner surface of the translucent plate of the storage case by providing ventilation into the heat receiving tube storage case, thereby preventing a decrease in heat collection efficiency due to condensation. be.

The present invention aims to make it possible to easily align the collector section and hot water storage section when they are connected by simply adding a simple modification to the above dew condensation prevention structure, and to allow rainwater to flow from the ventilation hole into the storage case. It is an object of the present invention to prevent the intrusion of foreign substances by making effective use of the original structure and simplifying the structure.

Next, embodiments of the present invention will be described based on the drawings.

As shown in Figures 1 and 2, two collectors are constructed by storing a plurality of heat receiving tubes 4 in parallel in a case 3 consisting of a bottom plate 1 made of heat insulating material, a transparent top plate 2, etc. A hot water storage section 10 is constructed by connecting and fixing the sections 5 in parallel in the width direction with connecting fittings 6, and attaching a hot water storage tank 8 and a cover 9 that covers the top and sides of this tank 8 to a base 7. are connected and fixed to the upper parts of both the collector parts 5, 5 by a connecting fitting 11, and the water supply pipe 12 to each heat receiving pipe 4 in each collector part 5 and the hot water return pipe 13 from each heat receiving pipe 4 are connected to each other by bellows. It is connected to the hot water storage tank 8 by a hose 14, and then cold water is supplied to the water supply pipe 1.
5, the supplied water is circulated by natural convection between the hot water storage tank 8 and the heat receiving pipe 4, heated by solar heat, and the hot water is taken out from the hot water storage tank 8 via the hot water supply pipe 16. A solar water heater is constructed as follows.

In each of the collector parts 5, as shown in FIGS. 2 to 4, ventilation holes 17 for the inside of the storage case 3 are provided at both ends of the lower end side of the bottom plate 1,
In addition, a cylinder 18 that forms a vent for the inside of the storage case 3 is attached to one end of the upper side of the storage case 3 with one end protruding outward from the storage case 3, and the collector part 5 and the hot water storage part 10 are attached. The protrusion of the cylindrical body 18 from the storage case 3 is inserted into the through hole provided in the tank cover 9 so that the cylindrical body 18 is inserted and the collector part 5 is positioned with respect to the hot water storage part 10 when the cylindrical body 18 is connected. Insert it, open the upper vent into the inside of the tank cover 9, and then ventilate into the storage case 3 through the opening on the bottom side of the hot water storage part of the tank cover 9 and both the upper and lower vents 17,
In addition to preventing dew condensation on the inner surface of the translucent top plate 2, the tank cover 9 is used to cover the upper ventilation opening to prevent rainwater from flowing through the upper ventilation opening into the storage case 3.
Efforts are made to prevent this from entering.

In summary, the present invention provides the above-mentioned solar water heater with the cylinder body 18 forming the vent.
A through hole is provided in the tank cover 9 of the hot water storage section 10 to protrude from the upper part of the storage case 3 and into which the cylindrical body 18 is inserted for positioning the collector section 8 connected to the hot water storage section 10. characterized by things.

That is, by modifying the cylindrical body 18 into one that protrudes from the upper part of the storage case, by simply providing the through hole, a member for aligning the collector section 5 and the hot water storage section 10 as well as rainwater can be removed from the storage case 3. Tank cover 9, which is originally configured as a member to cover the vent so that it is difficult for things to get in.
As a result, the collector part 5 and the hot water storage part 9 can be easily aligned, lined up, and prevented from entering the storage case 3 with a simple structure that does not require special members. As a result, assembly work can be carried out efficiently, and it is now possible to construct a device at a low cost that is less likely to have foreign objects entering the storage case and reducing heat collection efficiency.
