Abstract

PURPOSE: To efficiently heat water in a warm-water tank by heat insulating and storing generated warm water in the tank, and providing a heat transfer passage for communicating an inner space surrounded by a surrounding member with the inner space of a warm water tank casing. CONSTITUTION: Solar light emitted into a warm water tank casing 1 is emitted to the inner surface of the casing 1 and the outer surface of a surrounding member 7. The casing 1 and the member absorb the energy of the light since they are formed of a metallic material, and become in high temperature states. The interior of the casing 1 is heated, and the heated air is convected so that the entire interior of the casing 1 becomes at a high temperature. The high- temperature air at the outside of the member 7 is fed to the inside of the member 7 via a heat transfer passage 9 to heat the water in a warm water tank 4 via the wall of the tank 4. In addition, it is also heated by radiation heat from the surfaces of the casing 1 and the member 7 made of the metallic material.

う問題があった。However, the above-mentioned conventional solar water heater requires not only the heat receiving chamber but also a hot water tank provided separately from the heat receiving chamber, and the heat receiving chamber has a large number of thin tubes. It had to be installed. For this reason, a lot of work and a great deal of cost are required for the manufacture. In addition, since a heat insulating material is used to keep warm water warm, the warm water retention time is relatively short, and the hot water generated during the day cools down to room temperature water at midnight on that day. There was a problem.

Then, the sunlight that has entered the light-transmitting cover made of the light-transmitting material penetrates the light-transmitting cover and enters the inside of the water heater casing. The sunlight that has entered the inside of the water heater casing reaches the inner surface of the water heater casing and the outer surface of the surrounding member. here,
Since the water heater casing and the surrounding member are both made of a metallic material, they sufficiently absorb the energy from the sunlight that has reached them and reach a high temperature state.

る。When the water heater casing and the enclosing member reach a high temperature in this way, the air inside the water heater casing is heated by heat conduction or heat radiation from these surfaces. The heated air causes convection and the entire inside of the water heater casing becomes sufficiently hot. Further, the high temperature air outside the surrounding member flows into the inside of the surrounding member through the heat flow passage, and the high temperature air that has flowed in heats the water in the warm water tank through heat conduction through the structural wall of the warm water tank. Also,
The heating of the water in the hot water tank is achieved not only by the convection of the hot air described above, but also by the heat radiation from the surfaces of the water heater casing and the surrounding member made of a metal material.

十分に達成される。On the other hand, when the irradiation amount of sunlight is reduced, such as at dusk, heat is transferred from the hot air inside the water heater casing to the outside of the water heater. However, since the hollow portion of the hollow wall for the casing and the hollow wall for the surrounding member is in a vacuum state, heat transfer is limited. Therefore, the high temperature state of the air inside the water heater casing is maintained for a long time. Especially, since the flow of heat from the air existing in the inner space surrounded by the surrounding member is limited by the hollow wall for the surrounding member, the transfer of heat from the warm water tank to the surrounding air is also sufficiently limited, and the warm water is Insulation of hot water in the tank is sufficiently achieved.

る。Next, the operation of the above-mentioned embodiment will be described. The buried type vacuum water heater according to the above-described embodiment is placed on the roof of a house, for example. Then, the room temperature water is supplied to the inside of the warm water tank 4 while removing the air inside the warm water tank 4 by using the exhaust means 10. When the inside of the warm water tank 4 is filled with water, the water supply to the warm water tank 4 is stopped.

からのエネルギーを十分に吸収して高温状態になる。Then, sunlight is incident on the glass cover 3 formed of a light transmissive material, and the incident sunlight penetrates the glass cover 3 and enters the inside of the water heater casing 1. The sunlight that has entered the inside of the water heater casing 1 reaches the inner surface of the water heater casing 1 and the outer surface of the surrounding member 7. Since both the water heater casing 1 and the surrounding member 7 are made of a metal material, they are sufficiently absorbed in the energy from the sunlight that has reached them, and are brought into a high temperature state.

からの熱輻射によっても達成される。When the water heater casing 1 and the surrounding member 7 are in a high temperature state in this way, the air inside the water heater casing 1 is heated by heat conduction or heat radiation from these surfaces. The heated air causes convection, and the entire inside of the water heater casing 1 has a sufficiently high temperature. In addition, the high-temperature air outside the enclosing member 7 passes through the heat flow passage 9 and the enclosing member 7
The hot air that has flowed into the inside of the hot water tank 4 heats the water inside the hot water tank 4 by heat conduction through the structural wall of the hot water tank 4. The heating of the water inside the hot water tank 4 is achieved not only by the convection of the hot air described above, but also by the heat radiation from the surfaces of the water heater casing 1 and the surrounding member 7 made of a metal material.

て再び高温状態になる。When using the hot water in the hot water tank 4, the faucet 12 is opened and the hot water is taken out through the water intake pipe 5. Then, normal temperature water corresponding to the amount of hot water used is supplied to the hot water tank 4 through the water supply pipe 6. Hot water tank 4
When normal temperature water is replenished to the tank, the temperature of the water inside the warm water tank 4 is temporarily lowered, but the above-described action absorbs solar heat and returns to a high temperature state.

可能となる。On the other hand, when the irradiation amount of sunlight decreases at dusk or the like, heat is transferred from the hot air inside the water heater casing 1 to the outside of the water heater. However, since the hollow portions of the hollow walls 2 and 8 for the casing and the surrounding member are in a vacuum state, heat transfer is limited.
Therefore, the high temperature state of the air inside the water heater casing 1 is maintained for a long time. In particular, the heat flow from the air existing in the internal space surrounded by the surrounding member 7 is sufficiently limited by the surrounding wall 8 for the surrounding member, so that the heat transfer from the warm water tank 4 to the surrounding air is also sufficient. Therefore, the warm water in the warm water tank 4 is sufficiently kept warm. Therefore, the warm water generated during the day can be used even at midnight, and hot water can be supplied to the bath unit even at night, for example.
