Description

[Detailed explanation of the invention] <Industrial application field> This invention relates to a combination boiler that uses both electric heat and solar heat.

<Problems that this invention aims to solve> Originally, solar water heaters not only do not work at night or in bad weather, but also generate little heat even on sunny days, so they require large and wide-area light collecting plates. It was hot. The present invention attempts to solve such problems.

<Purpose of the invention> The purpose of the invention is to obtain a small and movable compound boiler that can supply a large amount of high-temperature water by using both solar heat during the day and idle electricity during the night.

<Structure of the invention> The present invention is a solar heat utilization system in which a large number of condensing water pipes are connected and arranged in parallel on the inclined surface of a support stand which has a downwardly inclined surface on the front surface and casters for movement are attached to the bottom surface. A heat collector is mounted, a large tank with a built-in medium heat tank heated by electric heat is provided on the rear surface of the heat collector, and a circulation path for a heat medium with a circulation pump is provided between the medium heat tank and the heat collector. A combined electric heating and solar heating combined boiler is characterized in that a thin coiled tube connected to a cold water supply pipe and a hot water extraction pipe is wound around the outer surface of the intermediate heating tank.

<Example> Examples will be described below based on the drawings.

A support base 1 having a downwardly inclined surface of about 45 degrees on the front side is formed. A solar heat collector 11 is installed on the slope.
be installed. The heat collector 11 is constructed by accommodating a large number of light collecting tubes 9 into which water pipes 10 are inserted in a horizontally parallel manner in a box frame 11a with a moisture-proof plate 12 placed on the bottom surface. Each water pipe 10 is connected in series. A large tank 2 in contact with an inclined surface is mounted on a support stand 1 on the rear side of the heat collector 11, and a medium heat tank 3 in the shape of a vertically long tank body is installed vertically in the center of the large tank 2. The inside of the medium heat tank 3 accommodates a small adhesive heat medium, and is provided with an inlet pipe 4 at the top and an outlet pipe 5 at the bottom, which are connected to water pipes 10 at the upper and lower ends of the heat collector 11, respectively. A circulation pump 13 provided in the middle of the downward pipe 5 is sandwiched therebetween to form a circulation path for the heat medium passing through the heat collector 11 and the intermediate heat tank 3.

14 is a photosensitive antenna for solar heat installed at the lower front of the heat collector 11, and the signal circuit 14a is
The circulation pump 13 is controlled through. Further, the direction of the heat collector 11 can be adjusted by moving the support base 1 in a direction suitable for exposure to light using the shadow of the antenna. A thin coiled tube 6 is wound around the outer periphery of the medium heat tank 3, and a cold water supply pipe 7 from outside the large tank 2 is connected to the lower end of the coil tube 6, and a hot water outlet pipe 8 is connected to the upper end of the coil tube 6, so that heated hot water can be obtained. . A heating wire 15 is wired between the large tank 2 and the medium heat tank 3 as shown in FIGS. 1 and 2, and an inexpensive and heat-resistant heating medium is filled. A switchboard 16 is attached to the side surface of the support stand 1 connected to the heating wire 15, and a time switch 17 and an automatic circuit breaker (not shown) for danger prevention are installed there so that the heating wire 15 can be connected only late at night.
It is designed to supply electricity to the

As shown in Fig. 2, the medium heat tank 3 is horizontally flat and vertically long, and is fully accommodating a fluid heat medium with low viscosity. The circulation pump 13 can circulate the heat medium with a small pump pressure in order to fill the water pipe 10 at the location.

Therefore, during the day, the solar heat collector 11 is used, and late at night, the medium heat tank 3 is constantly heated using idle electricity through the heating wire 15 and the heat medium inside the large tank 2, and the heating is wrapped around the tank. The cold water supplied to the attached coil thin tube 6 is heated and taken out.
Note that when the amount of light exposure of the photosensitive antenna 14 increases beyond the limit, the heat collector 11 controls the circulation pump 13 through the signal circuit 14a to increase the circulation speed of the heat medium in the water pipe 10, so that the heat collector 11 does not become excessively hot. This is to prevent damage caused by heat. It is also possible to adjust the direction of the heat collector 11 to a direction suitable for receiving light by moving the support base 1 while looking at the shadow of the photosensitive antenna 14. Furthermore, the supply of electric power to the heating wire 15 in the large tank 2 is adjusted by turning on and off an automatic circuit breaker depending on the heating state of the medium heating tank 3.

The large tank 2 also has the role of keeping the medium heat tank 3 warm by surrounding the medium heat tank 3 with the heat medium filled therein.

<Effects of the invention> As described above, the present invention includes a large tank heated by electric power mounted on a movable support stand, and a vertical medium heat tank housed in the large tank and the front side of the support stand. By forming a circulation path for a small sticky heat medium between the solar heat collector equipped with multiple concentrating water pipes,
A medium-heat tank is heated during the day by the circulating inflow of heat medium heated by solar heat, and at night it is heated using, for example, idle electricity late at night, so a coil wrapped around the medium-heat tank is used. This produces the effect that high-temperature heated water can be taken out at all times through the thin tube. Since the medium heat tank is housed in the large tank and surrounded by the heat medium, the medium heat tank has the effect of being kept warm by the large tank and the heat medium.

In addition, a photosensitive antenna is installed in front of the heat collector,
Since the circulation pump is controlled according to the amount of light exposure of the antenna, there is an effect that the heat collector is not damaged due to excessive light exposure, and the heat collector is not exposed to light due to the shadow of the antenna. This produces the effect that the object can be moved and directed in the optimal direction.
