Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hot water supply system, and more particularly to a hot water supply system comprising a plurality of hot water supply units using an electric heating instantaneous water heater having a plasma heater.

[0002]

2. Description of the Related Art Most electrothermal converters used in conventional electric heating instant water heaters utilize heat generated by an electric resistor, but for use in, for example, household water heaters. Since the equipment is extremely large, it was common to use a hot water storage type. On the other hand, JP-A-1-
Japanese Patent Publication No. 98854 discloses a new electric heating type instantaneous water heater that utilizes the heat generated by an arc plasma and has a feature that this type of instantaneous water heater can be greatly downsized. Regarding the details of the principle and the configuration, the duplicate description with the above cited document is omitted, but an arc plasma heating vessel made of a material having a high thermal conductivity such as Cu is filled with an inert gas such as Ar. The discharge space is formed, and a high voltage is applied to the electrode inside the arc space to generate arc plasma, and the generated heat is used to bring into contact with the container and to be introduced into the water to be heated such as city water. The heat exchange is performed to raise the temperature of the water to be heated and supply it to the outside. As described above, since this type of arc plasma heat generating portion is small and has a high heat energy density, it has an advantage that it can be remarkably downsized as compared with the conventional instantaneous water heater.

[0003]

However, when this is installed in a source of heated water such as city water as in the prior art, and when branching to a plurality of remote local positions to supply hot water, instantaneous boiling is required. There was an unavoidable drawback that the temperature of the hot water output from the vessel decreased due to heat loss in the middle of the piping.

The present invention has been made in view of the above problems, and it is an object of the present invention to provide a new hot water supply system comprising a plurality of hot water supply units of this type which are substantially free of heat loss. ..

[0005]

For this reason, according to the present invention, an electric arc is provided internally with a plasma heater for forming arc plasma in the discharge space and raising the temperature of the water to be heated by the generated heat. A plurality of hot water supply units consisting of instantaneous heating water heaters are arranged in parallel from the supply pipe of the water to be heated, and each plasma heating device driving power supply unit of each hot water supply unit is supplied to separate them intensively. It is intended to achieve the above-mentioned object by being configured.

[0006]

With the above-described hot water supply system configuration, a small-sized instant water heater equipped with each plasma heating device is provided immediately in front of the hot water supply port (for example, a stopcock (currant)) of each hot water supply unit at the local position. Therefore, the heat loss in the pipe from each plasma heating device to the hot water supply port is substantially eliminated, and the desired set temperature can be obtained. Further, since it is possible to wire from the driving power supply device centrally integratedly arranged to these plural plasma heat generators, it is advantageous in terms of installation space and cost as compared with the case where the power supply device is provided for each hot water supply unit. ..

[0007]

EXAMPLES The present invention will be described below based on examples. FIG. 1 shows a schematic configuration diagram of an embodiment of a hot water supply system according to the present invention. (Structure) 1 includes a plurality of (3 in the illustrated example) branching from city water pipes 5 at local positions such as general public or home kitchens, bathhouses, and washrooms. It is an electric heating instant water heater, and each has a plasma heater 2 inside. Each water stopper 1 is provided in the vicinity of each water heater 1 as a hot water supply port. 6
Is an integrated power supply device separately installed to drive the discharge electrode of each plasma heating device 2, and is a rectifier circuit from a commercial power supply,
A current control circuit, a high voltage generation circuit, and the like are included, and each wiring 7 is connected to the electrode portion of the plasma heating device 2 of each unit. Reference numeral 4 denotes a city water introduction part as heated water.

(Operation) As described above, the piping from the heat exchange part of each water heater 1 to the calan 3 as each hot water supply port can be extremely short, so that the temperature of the output hot water does not substantially drop. In addition, it is convenient because the required hot water temperature can be set individually by a hot water temperature setting device (not shown) provided close to the position of each curran 3, and the discharge electrode driving power source of each plasma heating device is integrated. It is extremely economical because it is created and placed separately.

[0009]

As described above, according to the present invention, since each hot water supply unit provided with a plasma heating device can be arranged immediately before the hot water supply port at each local hot water supply place, each hot water supply port can be provided. There is virtually no heat loss in the piping, and since the driving power source for each plasma heater is integrated and installed separately, it is extremely economical compared to the case where each hot water supply unit is installed. is there.
