Abstract

PURPOSE:To efficiently collect solar light rays and to generate and store hot water by coupling a low temperature part of one end of a heat pipe to heat radiation fins attached to a water storage tank, and coupling a high temperature part of the other end of the pipe to a solar heat absorption member. CONSTITUTION:A solar heat hot water heater is composed of a hot water storage tank body 1, a heat collector 9 and a heat pipe 18. The body 1 is formed in a longitudinally long cylindrical shape formed in a heat insulating and adiabatic structure, and detachably covered with a cover 2. When cold water is supplied from a cold water supply pipe 3 into the body 1 and arrived in the vicinity of the upper end of the body 1, a float valve unit 6 is operated to automatically stop supplying. A sun tracing mechanism 17 contained in a base 14 of the collector 9 is so operated to be finely rotated at a slow speed as to always direct the collector 9 toward the sun. When the solar light rays are radiated to the surface of a heat absorption plate 12 of the collector 9, a heat collecting plate 13 becomes a high temperature so that medium in a high heat unit 20 of the pipe 18 is evaporated to move to a multi-end low temperature unit 19 and to dissipate heat from heat radiation fins 8. Thus, cold water in the body 1 is rapidly heated to hot water state.

Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to a water heating device that utilizes solar heat.

(Prior art) Conventional solar water heating devices are constructed of a flat frame with a built-in heat receiving device, which is installed on a south-facing roof or rooftop with an angle toward the sun to efficiently utilize solar heat. It was designed to be collected in a targeted manner.

(Problem to be Solved by the Invention) However, it is a well-known fact that in recent years, as land prices have increased, more and more residences have become apartment complexes, and that the number of high-rise buildings is rapidly increasing, especially in urban areas.

This not only makes it difficult to install conventional solar water heating systems on sloping roofs or rooftops, but even if water heating systems are installed on roofs or roofs, the utilization rate for residents is low. There is a drawback that solar heat cannot be used effectively as the amount of solar heat is decreasing more and more.

In view of the above-mentioned drawbacks of the conventional technology, the present invention has been made to solve this problem by making the device a separate type in which the water tank and the heat receiving part are separated. To obtain a solar water heating device that can be compactly installed at a desired location such as a terrace or rooftop, and efficiently collects solar heat to generate and store hot water.

(Means for Solving the Problem) As a means for solving this problem, the present invention connects the low-temperature part at one end of the heat pipe to a heat radiation fin installed in the water tank, and directs the high-temperature part at the other end toward sunlight. It is connected to a heat absorbing member that collects solar heat, which is incorporated into a heat collection device attached to a solar cell.

(Example) An example in which the concrete configuration of the present invention is shown in the drawings will be described in detail below.

This embodiment is used in a water heater, and is composed of a hot water storage tank body 1, a heat collecting device R9, and a heat pipe 18, and the hot water storage tank body 1 is formed in a vertically elongated cylindrical shape with a heat-insulating structure. , the lid body 2 is removably covered.

A cold water supply pipe 3 and a hot water extraction pipe 7 are attached to the lid body 2, and the cold water supply pipe 3 is inserted into the tank body 1 almost to the bottom of the tank body 1 by opening the supply port 4 with a cold water turbulence prevention plate 5 attached to the lower end. At the same time, there is a tank body 1 at the top of the pipe 3.
A float valve device 6 is attached to keep the water level in the tank constant at all times, and one hot water extraction vibe 7 is inserted to the center of the tank body 1.

In addition, a heat vibrator 18 (to be described later) is installed at the bottom of the tank body 1.
Attach the heat dissipation fins 8 connected to the fins.

The heat collecting device 9 includes a heat absorbing plate 12 whose surface is chemically blackened so as to efficiently absorb sunlight in an I/Using 10 whose surface is covered with a transparent glass 11, and a thermal conductivity plate on the back side of the heat absorbing plate 12. Good for example copper etc! , + lJ: , heat collecting plate 13
Incorporate it by touching it! &The base 14 is attached to the support 15 erected on the base 14 by a pivot joint 16 that can be raised and lowered.
A solar tracking device $17 is built inside, and the heat collecting device 9 is attached via a support 15 so that the heat collecting device 9 always faces Daikoku, and rotates at a minute angle in steps of, for example, 30 minutes.

Further, the elevation angle with respect to the celestial altitude is determined by manually rotating the shaft joint 16 portion of the support column 15.

Heatvibe 18 is Freon like the well-known one. It has a structure in which a heat medium such as ammonia is sealed, and the low temperature part 19 at one end is connected to the heat radiation fin 8 installed inside the tank body l, and the high heat part 20 at the other end is connected to the heat collection plate 13 of the heat collection device 9. do.

Then, the tank body 1 is installed in a room or the like that is not exposed to sunlight, the heat collecting device 9 is installed in a sunny balcony or the like where it can directly receive the sun's rays, and the operator is connected with a heat vibrator 18.

Now that it's configured like this, to use it,
First, cold water is supplied from the cold water supply pipe 3 into the tank body l. When the cold water reaches near the upper end of the tank body 1, the float valve device 6 is activated to automatically stop the supply of cold water and store a certain amount of cold water.

Next, a sun tracking mechanism 17 built into the base 14 of the heat collecting device 9 is made to rotate at a very slow speed so that the heat collecting device 9 always faces the sun. In this state, when sunlight irradiates the surface of the heat absorption plate 12 of the heat collection device 9, the heat collection plate 13 in contact with the back side becomes high temperature, and the heat vibrator 18 connected to it becomes hot.
The medium in the high temperature section 20 evaporates and moves to the low temperature section 19 at the other end, where heat is radiated through the heat dissipation fins 8 connected thereto. Thereby, the cold water in the tank body 1 can be quickly brought to a hot water state.

In addition to the above-mentioned embodiments, the following embodiments may also be implemented.

(1) Instead of installing the heat radiation fins inside the tank body, the heat radiation fins connected to the heat pipes may be placed in an aquarium, bathtub, etc., if necessary.

(2) In winter, the low-temperature part of the heat pipe can be brought into the kotatsu to supplement the heat source of the kotatsu. (3) The heat collection device and the tank body can be integrally connected. Also good.

(Effects of the Invention) As described above in detail with practical examples, this invention is configured as a separate type in which the heat collecting device and the water storage tank are connected by a heat pipe, so it can be used on a narrow sunny balcony etc. If only a heat collection device is installed, it can be used as a solar water heating device even if the water tank is installed indoors or in a place that does not get sunlight, and it can be used not only in high-rise houses but also in single-family houses on balconies and terraces. Alternatively, there are no particular restrictions on the installation location, such as on a rooftop, and it can be installed compactly anywhere.

In addition, the solar heat collected by the heat absorbing member built into the heat collecting device is radiated by the heat vibrator through the heat radiating fins in the water tank to heat the cold water. The solar heat collected by the heat absorbing member built into the heating device can be used without wastage to quickly heat the cold water in the water tank, providing an excellent effect of providing an efficient solar water heating device. It is something that you have.
