Abstract

PURPOSE:To simplify the mounting work and improve the heat collecting efficiency by a structure wherein circulating pipes for connecting a heat collector and a hot water storage tank are arranged and fixed on the back of a frontal plate fitted to the front of frames in the natural circulation type water heater utilizing solar heat. CONSTITUTION:A plurality of the pipes 8 are formed upward and downward integrally or otherwise with the frontal plate 5 by being arranged and fixed on the back thereof by blow-molding or the like. And the heat collector 1 and the hot water storage tank 2 are placed on both the roof surfaces over a ridge 3 respectively and connected with each other by means of the frames 4 and then the pipes 8 are coupled through flexible pipes 9 to the water pipes 6 and 7 of the heat collector 1 and of the hot water storage tank 2 respectively. After that, the frontal plate 5 is fitted to the frame 4. Due to the structure as described above, the mounting work of the water heater is facilitated as well as the heat collecting efficiency is improved, because the pipes 8 are covered with the frontal plate 5.

Description

Detailed Description of the Invention This invention provides a heat collector (1) and a hot water tank (1) on both sides of the ridge (3).
2)) Pertains to a natural circulation type solar water heater that is placed in a distributed manner.

What is shown in Fig. 1 and 2m is a conventional system of this kind, in which the heat collector 5 (1) and the hot water storage tank C) are connected by a frame member) that straddles the ridge G4). A front plate (5) is arranged at the front, and a heat collector (1) and a hot water storage tank (2) are placed under the front plate (5).
A circulation pipe (6) was installed to connect the two. However, if this circulation pipe (6) drips down onto the ridge (3), the efficiency of the natural circulation of the heated water will deteriorate. It was a complicated work to fix the circulation pipe (6) to the back surface of the front plate (5) in order to prevent the circulation pipe (6) from sagging.

The present invention seeks to eliminate the above drawbacks.

The present invention will be explained below based on an embodiment shown in FIGS. 3 to 5.

In the drawing, (1) is a panel-shaped fish collector, (2) is a box-shaped hot water tank, and (4) is a side of the hot water tank (2) and a fish collector (1).
);
(5) is the front plate, (6) is the water pipe protruding from the center of the upper end of the heat collector (11), and (7) is the water pipe protruding forward from the front of the upper end of the hot water tank (2). be.

The front plate (shi) is bent to bulge upward in the front, and a plurality of pipes (@) are arranged and fixed in the vertical direction on the back side. The upper and lower ends of this pipe shaver are the front plate (
5) Raise it slightly to make it easier to connect. The front plate (5) and the pipe (-) may be formed separately and then integrated, but if polyethylene resin or the like is used, they can be integrally formed by blow molding.

Therefore, this natural circulation solar water heater has a heat collector (1) and a hot water storage tank (2) placed on both sides of a ridge (3) on the roof, and the two are connected by a frame (4). After that, connect both water pipes 1B) and (7) using the pipe @), and then attach the front plate (5) to the pedestal (4) so as to cover the pedestal (4). Ru. If a flexible pipe (9) is used for the connection, it will be easier to attach the front drawing board (5) to the iron stand (4).

Become.

The natural circulation type solar water heater according to this invention is described below.

Since it consists of the above-mentioned structure, there is no need to arrange the pipe (8) on the back of the front plate (5) during construction, and the pipe (8) does not hang down on the convenient slope. .

Furthermore, the front drawing board (5) and the K-coated pipe (8) also improve the heat collection effect. In addition, it is convenient to have more pipes (8) than required so that you can use them selectively.
