Abstract

PURPOSE: To convert solar light into hot water efficiently and make the device light in weight and compact by providing a specular light-converging plate, a heat exchanger, and a supplementary heater. CONSTITUTION: A specular heat collector 3 which is a hemispheric body without an upper half is set an angle of a good light-condensing ratio. A heat-exchange coil pipe 4 is attached to the specular heat collector 3. For the foundation 1 a water storage tank C having a solar-light-screening shutter interlocking with a temperature sensor is provided, which is fitted around the periphery with a heatproof device B and inside which a supplementary heater (j) is set by fixing it with fitting members of such materials as will not dissolve, as rust or as an impurity, in the water tank. Ordinarily, the operation is controlled by an automatic controller and also manually. A heat-exchange part and the water storage tank C are connected by piping with a circulating pump G. This constitution enables freely setting the water-storing capacity in installation and provides an apparatus which is structurally heatproof and earthquake- resistant and enables effective utilization of energy by a clean, pollution-free method.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for converting solar heat into a large amount of hot water efficiently in a lightweight and compact form, and a block assembly for simplifying the addition.

[0002]

2. Description of the Related Art Conventionally, a hot water system utilizing solar heat has installed a heavy-weight device having a water tank on the roof.

[0003]

[Problems to be solved by the invention]

B. Conventionally, the heat exchanger and the water storage tank were integrated into one unit, which was heavy and difficult to install. The hot water capacity was easily affected by the weather. Had to install it all over the roof in order to have a large capacity. D, multipurpose use was impossible. The present invention solves the above drawbacks.

[0004]

[Means for Solving the Problem] A lower hemispherical mirror collector (3) attached to a base (1) with a fixing bracket (2) is connected to a water absorption pipe and is near the center of the mirror collector (3). A heat collecting part consisting of a heat exchange coil pipe (4) formed in a coil shape and connected to a drain pipe and a water storage tank for storing water, and suction and suction to a water supply pipe and a drain pipe connected from the water storage tank to the heat exchanger (4). A circulation motor (G) provided for heat exchange and hot water distribution, a temperature sensor for measuring the water temperature in the water tank, a heat storage device (D) provided in the water tank, and a heat insulating material and a heat insulating material for enclosing the water tank (C). A hot and cold water collecting device using Daiyo heat, which comprises a water storage unit having an outer frame of a seismic resistant structure for protection, a sensor for controlling the water level sensor (K), and a control device for controlling a circulation motor.

[0005]

In the use of the present invention, the automatic control device and the manual operation are performed during the daylight hours, and the makeup water is automatically stopped when the water level in the water tank (C) is close to the full water level, and the circulation pump causes the heat exchanger and the water tank (C). When the set water temperature reaches the set temperature, the heat exchange function is automatically stopped by the temperature sensor installed in the water tank and the hot water is supplied, and it takes time to reach the set temperature for the first time, but it can be set freely thereafter. Can supply hot water.

[0006]

Embodiments of the present invention will be described below. (B) The lower hemispherical mirror collector (3) is installed at an angle with a good light collection rate, and the heat exchange coil pipe is installed in the center of the bottom of the hemisphere with a good heat exchange rate. (B) The heat exchange coil pipe (4) is attached to the specular heat collector (3), the base (1) is securely installed with a fixing metal fitting, and a device for preventing accidents other than when using due to reflection of the specular heat collector is linked to the temperature sensor. We have installed a sunlight blocking shutter. (C) The water storage tank is equipped with heat-insulating equipment around the outer circumference of the water tank, and stones or far-infrared ceramics with high heat storage efficiency are fixed and arranged in the water tank with a member that does not elute rust or impurities. (2) Normal operation was automatic control and manual. (E) The heat exchange section and the water storage tank section (C) were connected by a heat-proof pipe and a circulation pump (G). (F) A heat-insulating material (B) and (A) for efficiently protecting (B) are provided on the outer periphery of the water storage tank. (And) If it cannot be buried due to the location of the installation site, it will be an all-weather water tank with heat treatment. The present invention has the above-mentioned constitution, and when it is used, it is as follows. In the use of the present invention, the water level in the water tank (C) is filled with water by the automatic control device and manually operated during the daylight hours. When the water supply is automatically stopped in a close state, the circulation pump operates, the heat exchanger and the water tank (C) circulate, heat exchange is measured, and when the set water temperature reaches the set temperature, the heat exchanger (4 ) Function automatically stops and becomes hot water supply state, it takes time to reach the set temperature for the first time use, but it is possible to freely supply hot water thereafter.

[0007]

EFFECTS OF THE INVENTION The present invention is inconvenient because it cannot be used when a solar light-utilizing mirror plate, a heat exchanger, and an auxiliary heater (J) are provided, and the heat storage device (D) is built in the water tank. It is a device that eliminates the problem and allows the user to freely select and construct the water storage capacity of the underground underground water tank according to the usage fee.
