[Prior Art]

 Japanese Patent Application Laid-Open No. 1-252898 discloses an example of hot water supply equipment in which a heat storage body is used as a heat source and a heat pipe is used as a heat transport means. This uses a high melting point material such as a metal block or ceramic block as a sensible heat storage body, and this heat storage body and the heat exchanger for hot water are connected by a loop type heat pipe, and the heat exchanger for hot water is connected to the heat exchanger. An on-off valve that stops the flow of hydraulic fluid is provided in the middle of the heat pipe line where the hydraulic fluid returns to the heat storage side. According to the hot water supply equipment with such a configuration, the time period for storing heat can be freely selected, so it is possible to use night power to reduce operating costs, and the heat pipe has an excellent heat transport capacity. Since it is equipped, the time lag for hot water discharge is short, and the heat storage temperature is raised to reduce the volume of the heat storage body, making it a compact facility.

[0003]

[Problems to be solved by the device]

 In the above-mentioned conventional hot water supply equipment, a sensible heat storage material is used in order to improve the thermal response and increase the heat storage amount per unit volume, and the heat storage temperature is raised. Since it is configured to take out heat from the heat storage body only by the heat pipe and specializes in equipment for hot water supply, it cannot be applied to other heat-related equipment. Therefore, for example, when the conventional hot water supply equipment is installed in a facility equipped with a heat source such as a sauna room, hot water can be supplied to the bathroom using the heat storage body as a heat source. It is necessary to provide a unique heat source for each location that does not require hot water, such as this, and as a result, the types and number of heat sources increase, and the heat-related equipment becomes complicated and large.

The present invention has been made in view of the above circumstances, and an object thereof is to provide a heat storage type hot water supply facility having a function other than hot water supply.

[0005]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the present invention relates to a heat storage type hot water supply facility in which a heat storage body and a heat exchanger for hot water are connected by a heat pipe. Part or all of the heat-insulating coating on the upper end side of the is configured to selectively open and close so as to allow heat dissipation from the heat storage body.

[0006]

[Action]

 The basic function of the hot water supply equipment of the present invention is the hot water supply function, but in addition to this, the heat storage body alone serves as a heat source other than hot water supply by opening the heat insulating coating on the top of the heat storage body to radiate heat. That is, hot water is supplied by the heat pipes sending heat to the heat exchanger to the hot water heat exchanger to heat the water supplied thereto. Also, if the heat insulation coating on the upper part of the heat storage body is opened, the heat from the heat storage body is released upwards.Therefore, install the heat storage body in the sauna room or under the heater in the kitchen. , The heat storage body functions as a heat source of them alone.

【Example】

 Next, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a schematic diagram showing an embodiment of the present invention. In the example shown here, the heat storage body 1 is used as a heat source for hot water supply and It is configured for use with an external heat source. The heat storage body 1 is a metal block, a ceramic block, or a sensible heat storage body in which these are combined, and is provided with an electric heater (not shown), and inside the evaporation pipe 3, which is a part of the heat pipe 2. It is buried. This heat storage body 1 is entirely covered with a suitable heat insulating material 4, and further has an exterior 5 provided on the outside thereof. Of these heat insulating material 4 and exterior 5, the upper end side portion of the heat storage body 1 is It is configured to be removable. The heat storage body 1 is arranged below or inside the heated portion 6.

The heat pipe 2 connects the evaporating pipe 3 and the condensing part 8 provided on the side of the heat exchanger 7 for hot water so as to form a circulation path as a whole by a vapor flow pipe 9 and a liquid return pipe 10. It is of a loop type, and an appropriate condensable fluid such as CFC or water is enclosed as a working fluid in the degassed state inside the circulation path. A reservoir 11 for accumulating a liquid-phase working fluid (working fluid) is provided in the middle of the liquid return pipe 10, and a control valve 12 is provided between the reservoir 11 and the evaporation pipe 3. There is. The hot water heat exchanger 7 heats the supplied water by the heat released from the condensing section 8 to make hot water, and sends the hot water to an appropriate place.

Therefore, in the hot water supply facility described above, when the control valve 12 provided in the heat pipe 2 is opened, the working fluid flows into the inside of the evaporation pipe 3, where it is heated by the heat of the heat storage body 1. After being evaporated, the steam flows through the steam flow pipe 9 to the condensing unit 8, where it radiates heat and condenses. As a result, the water supplied to the hot water heat exchanger 7 is heated and heated to become hot water. Become. When only such hot water supply is performed, the entire heat storage body 1 is covered with the heat insulating material 4 in order to prevent wasteful heat dissipation from the heat storage body 1. On the other hand, when heating the above-mentioned heated portion 6, the heat insulating material 4 on the upper end side of the heat storage body 1 is removed to radiate heat from the heat storage body 1. As the heated portion 6, a kitchen stove 13 shown in FIG. 2 or a sauna room 14 adjacent to a bathroom as shown in FIG. 3 is suitable. In the former example, hot water is supplied to the faucet 16 of the sink 15. On the other hand, when the stove 13 is used, heat is applied from the lower side of the stove 13 by removing the heat insulating material 4 on the upper end side of the heat storage body 1 installed under the stove 13 and radiating heat from the heat storage body 1. In the latter example, the heat storage body 1 is installed in the sauna room 14 and hot water is supplied to the bathtub 17, while the heat insulating material 4 on the upper end side of the heat storage body 1 is removed to radiate heat when using the sauna room 14. Heats the sauna room 14.

When the hot water supply is stopped, the control valve 12 provided in the liquid return pipe 10 is closed, and when the heating of the stove 13 and the sauna chamber 14 is stopped, the upper end side of the heat storage body 1 is closed. It is closed by the heat insulating material 4.

By the way, in the above embodiment, the heat insulating material 4 on the upper end side of the heat storage body 1 is removed to radiate heat from the heat storage body 1, but the invention is not limited to the above embodiment. For example, as shown in FIG. 4, the heat insulating material 4 on the upper end side of the heat storage body 1 is composed of two heat insulating plates 19 each having a slit-shaped opening 18, and one of the heat insulating plates 19 is slid. The heat storage body 1 may be opened upward by aligning the openings 18 with each other, and conversely, the heat storage body 1 may be closed by shifting the openings 18 into a non-matching state.

Further, in the present invention, when the heat storage body 1 is used as a heat source other than hot water supply, it is used as a heat source for an appropriate heated portion other than the heat source for the stove and the sauna room shown in the above-mentioned embodiment, if necessary. May be.

[Effect of the device]

 As is clear from the above description, according to the hot water supply equipment of the present invention, in addition to taking out heat from the heat storage body by the heat pipe, the heat insulating material on the upper end side of the heat storage body is opened to radiate heat from the heat storage body. Therefore, the heat storage body can be used as a heat source other than hot water supply alone, and therefore the usefulness of the hot water supply equipment of the present invention is increased, and the number of heat sources to be provided in the facility using this hot water supply equipment and the device for that are provided. Can be reduced.
