Description

DETAILED DESCRIPTION OF THE INVENTION "Industrial field of application" The present invention is designed to eject water in a hot-air chamber in which hot air is freely flowing into a hot-air chamber, which is pumped up by a rotating body, under uniform water pressure conditions. TECHNICAL FIELD The present invention relates to a hot water method and apparatus capable of quickly producing heated water by a heat exchange action by direct contact with the water.

"Prior Art" Conventionally, a hot water device capable of turning sprinkled water into hot water by a direct heat exchange action with hot air in the flowing-down process is known from, for example, Japanese Utility Model Publication No. 45-2382 before this application. The contents will be described with reference to FIG.

That is, the main body 1 is constituted by a combustion chamber 5 whose lower side is opened 9 and an endothermic chamber 2 in which one end is connected to the shower faucet 4 and an endothermic pipe body 3 is appropriately surrounded and arranged. In this structure, a hot water storage chamber 7 is formed by a tubular body 6, a flame dispersion 8 having a hot water discharge pipe 10 is located at the center lower side, and a burner 11 is provided at the lower side of the flame dispersion. It is a thing.

[Problems to be Solved by the Invention] In this type of conventional hot water device, however, the water sprinkling of water rises downward from above, and the hot air rises from above downward to directly heat the water and hot air in the flowing-down process. By exchanging it, the hot water was discharged as warm water. Therefore, the heat exchange action in the sprinkling state drops only once, so if you want to raise the temperature of the warming water, you need to reduce the sprinkling amount, so the exhaust temperature will inevitably become high. However, there is a problem that the gas cannot be circulated as it is, not to mention that it is exhausted with a large amount of water vapor.

According to the present invention, after the water in the water tank pumped up and discharged by the rotating body is press-fitted into the running water feed chamber arranged inside the running water guide body while increasing the pressure, the water is injected into the running water guide body by a large number of jets. Hot air can be ejected radially from the outlet into a hot air chamber where it flows freely under a substantially uniform water pressure condition, or part of the water in the water tank that has been pumped up and discharged can be directly blown from the jet port that is formed in the flowing water guide. At the same time as spouting into the room, other water is spouted in a radial direction into the hot air chamber where hot air flows under a substantially uniform water pressure condition from the spouts formed in the running water guide body.
It is an object of the present invention to provide a hot water method and apparatus capable of obtaining heated water by a heat exchange action by direct contact of the jetted water with hot air.

The running water guide body having the jet outlet is provided, the running water inlet chamber is provided inside the running water guide body having the jet opening, and the lower portion is submerged in water inside the running water guide body. The water in the water tank pumped and discharged by the rotating body that presses and discharges the water that has been pumped and discharged into the running water feed chamber is then pressed into the running water feed chamber that is arranged inside the running water guide body while increasing the pressure, and then the water is Hot air is ejected radially from a large number of jets formed in the flowing water guide body into a hot air chamber in which hot air flows freely under a substantially uniform water pressure condition, and heat is added by direct heat contact with the hot air in the water tank. Use hot water and carry out the above hot water method The hot water device used for this is to arrange a running water guide body in which a lower opening portion is exposed to the water surface or below the water surface on the water surface in the water tank, and moreover, a large number of jet outlets are formed on the surface, and the jet outlet is A running water inlet chamber is provided inside the open flowing water guide body, and a rotating body is freely rotatable inside the running water guide body, the lower part of which is submerged in water and pumped and discharged into the running water feed chamber. The lower part of the flowing water guide is exposed to the water surface outside the flowing water guide body, and a hot air cover is provided inside the hot water guide body to separate the hot air chamber through which hot air can freely flow. One side is provided with a hot air inlet port and the other side is provided with an exhaust port. Further, in the method for improving the basic hot water method described above, the lower opening part is provided on the water surface in the water tank. The water flow guide with a large number of jet holes on the surface And a flowing water inlet chamber is provided inside the flowing water guide body that opens the jet outlet. Inside the flowing water guide body, the lower part is submerged in water and pumped and discharged water is introduced. A part of the water in the water tank, which is pumped up and discharged by the rotating body that is press-fitted into the room, is radiated toward the hot air chamber where the hot air freely flows directly from the jet port formed in the flowing water guide, while other water is guided to the running water. A hot air chamber in which hot air freely flows under a substantially uniform water pressure condition from a plurality of jets of the water that have been injected into the running water inlet chamber while increasing the pressure. Is to be heated radially by direct heat contact with hot air in the water tank, and the water heater used to carry out the above-mentioned improved method is , Above the water surface in the tank, open the lower opening Surface or to face the underwater, yet disposed running water guiding body that 穿口 multiple jets on the surface,
Inside the running water guide body, a running water inlet chamber is provided to cover other jet outlets except for some of the jet outlets, and inside the running water guide body, the lower portion is submerged in water and pumped up water. A rotating body for discharging into the inlet chamber is rotatably mounted on a storage shaft, and a lower open portion is exposed to the water surface outside the flowing water guide body, and a hot air chamber through which hot air can freely flow is separated. A hot air cover is provided, a hot air inlet is provided on one side of the hot air chamber, and an exhaust port is provided on the other side.

In addition, a hot water device composed of a rotating body, a running water guide body having a running water inlet chamber, a hot air chamber, and a hot air chamber cover is floated above the water surface by a levitation body, and the hot water device is placed on a water surface having a large area. It is possible to move freely so that hot water work can be performed at a desired position.

Furthermore, by further arranging a heating device at the bottom of the water tank,
The water in the water tank is heated and the hot air is introduced into the hot air chamber.

"Operation" A certain amount of water is stored in the water pool in the water tank configured as described above, and then the rotating body whose lower part is immersed in water is rotated in the direction of the arrow, and at the same time the inside of the hot air introducing cylinder is The circulating hot air is introduced into the hot air chamber through the hot air inlet, which circulates the hot air in the direction of the arrow in the hot air chamber and then exhausts it through the exhaust port.

By so doing, a certain amount of water pumped up by the rotating body is vigorously discharged toward the inner surface of the flowing water guide body arranged outside the rotating body, and enters the flowing water inlet chamber arranged on the inner surface of the flowing water guide body. The extra water that is press-fitted is dropped into the water tank from the lower opening along the inner surface of the running water inlet chamber.

Therefore, even when the rotating speed of the rotating body is slow, the water continuously pumped up and discharged by the rotating body is forced into the running water supply chamber, resulting in a high water pressure and a large number of sprayed holes. The hot air is jetted vigorously from the outlet into the hot air chamber in which the hot air freely flows under a substantially uniform water pressure direction along the radial direction, and is in direct contact with the hot air flowing. As a result, the jetted water drops into the water tank from both ends of the hot air chamber cover while rapidly becoming heated water due to the direct heat exchange action with the hot air flowing in the hot air chamber, and is then pumped and discharged again by the rotating body. Since the heat exchange action similar to that described above is continuously repeated, the water quickly becomes high-temperature heated water. In addition, since a fixed amount of water is always stored in the water tank, the amount of hot water supplied is the same as the amount of water supplied, and the amount of water jetted in the hot air chamber is always kept constant regardless of the increase or decrease in the amount of water supplied. It is possible to continuously and quickly obtain warm water having an appropriate temperature without waste. Further, in the hot water method and the apparatus therefor according to claims (3) and (4), a certain amount of water is stored in the water pool portion in the water tank, and then the rotating body whose lower part is immersed in the water is rotated in the arrow direction. At the same time, the hot air flowing in the hot air introducing cylinder is introduced into the hot air chamber through the hot air introducing port, which circulates the hot air in the hot air chamber in the direction of the arrow and then exhausts it through the exhaust port.

By the way, a certain amount of water pumped up by the rotating body is vigorously discharged toward the inner surface of the running water guide arranged outside the rotating body, and a part of the water is covered by the running water inlet chamber. Hot air freely circulates directly from the non-exhaust port directly into the hot air chamber along the radial direction, is in direct contact with the circulating hot air, and other water that is pumped and discharged continuously flows into the running water inlet chamber. Pressed in.

Therefore, even if the water pressure declines due to a portion of the water jetted directly in the radial direction, the water pressure in the running water inlet chamber increases due to the continuous press-in, resulting in a large number of jets. Hot air is vigorously ejected along the radial direction into the hot air chamber where free air is flowing more freely under a more uniform water pressure condition.
It comes into direct contact with the circulating hot air. In addition, excess water is dropped into the water tank from the lower opening along the inner surface of the running water inlet chamber.

As a result, the jetted water drops into the water tank from both ends of the hot air chamber cover while quickly becoming heated water due to the heat exchange action by direct contact with the hot air flowing in the hot air chamber, and then pumped up again by the rotating body. Since the heat exchange action similar to that described above is continuously repeated, the water quickly becomes hot water at high temperature.

In addition, since a water chamber is provided around the hot air introducing cylinder through which the hot air flows, it is possible to prevent burnout of the hot air introducing cylinder no matter how hot the hot air is allowed to flow. While opening the hot air inlet at the center side and opening the exhaust ports at both ends of the hot air chamber, the hot air introduced into the hot air chamber from the hot air inlet is circulated in different directions on the left and right sides, and water and hot air The improvement of heat exchange efficiency can be easily achieved.

Furthermore, since the water heater is floated above the water surface by a float, it can move freely over a wide area of the water surface.
Hot water work can be performed at a favorite position.

Further, since the heating device is arranged in the lower part of the water tank, it is possible to easily raise the temperature of the water or the heated water in the water tank to a desired temperature.

"Effects of the Invention" Since the present invention is configured as described above,
The following effects are achieved.

On the surface of the water in the water tank, the lower opening is exposed to the surface of the water or below the surface of the water, and a flowing water guide body having a large number of jet holes is provided on the surface. Is a running water inlet chamber, and inside the running water guide body, the lower part is submerged in water and pumped and discharged water is forced into the running water feed chamber by a rotating body. Since hot air was jetted radially into the hot air chamber where the hot air freely flows through the body, the water in the water tank is not directly guided to the outside of the water tank, but is brought into direct contact with the hot air in the water tank and heat is exchanged without heat loss. Since a large amount of water can be efficiently heated and the rotating speed of the rotating body is slow, even if the pumping amount is small, the pressure of the pumped and discharged water is gradually increased into the running water inlet chamber. While feeding it, you can increase the water pressure. As a result, it is possible to spray water into the hot air chamber in a radial direction from a large number of jet outlets under a substantially uniform water pressure condition, and to allow the water to be heated quickly, or at all times always store a fixed amount of water in the water tank. Therefore, the pumping and discharging amount of the rotating body is always kept constant regardless of the increase or decrease of the water supply, the heat exchange efficiency between the jetted water and hot air can be improved, and the exhaust temperature is as low as the hot water temperature. Not only can it be suppressed, but since a continuous circulation heat exchange action can be performed, rapid temperature rise can be easily achieved.

Moreover, the bottom of the water tank, in which the lower part of the rotating body is submerged, is recessed to provide a water pool, so that even if the amount of water in the water tank is small, a certain amount of water necessary for pumping up the rotating body is always stored. It is possible to increase the heating effect by keeping the pumping amount of the rotating body constant.

Furthermore, since the whole warm water apparatus is floated above the water surface by the float, even if the tank has a large area, the whole warm water apparatus can be moved to a desired position to easily accomplish the warm water operation.

Furthermore, since the water tank is heated by the heating device and the hot air after the action is introduced into the hot air chamber, the water is heated within a short time by the synergistic effect of the indirect heating action by the heating device and the direct heat exchange action with the hot air. It is possible to obtain heated water at an appropriate temperature.
