Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to a terminal device for hot water supply and space heating used in a central heating system.

(Prior art) Conventionally, in central heating systems, the heating medium for heating is constantly circulated, but the hot water for hot water supply is boiled to a high temperature of approximately 80°C in a hot water source, that is, a boiler. The hot water is led directly to the hot water supply location via an open hot water pipe and supplied to the faucet equipment.

Therefore, if the hot water supply distance from the hot water supply source to the faucet equipment is long, the water temperature will drop due to heat radiation while flowing through the hot water supply pipe, making it difficult to directly supply high-temperature hot water to the faucet equipment. However, when the faucet is not in use, the hot water in the hot water supply pipe cools down, so for a while after the faucet is opened, only low-temperature water is supplied to the faucet. The discharge temperature rises slowly.

In order to solve the above problem, hot water for hot water supply should be constantly circulated in the same way as the heat medium for heating, and central heating systems (hot water supply systems) using such a method are not currently available. ing.

However, since such a system requires a return circuit for hot water supply, the piping is large-scale, and the piping work is difficult and the cost is high.

On the other hand, conventional central heating terminals only have a single function, such as heating only for space heating and hot water only for hot water supply. ,
I had to install it.

(Problem to be solved by this invention) The problem to be solved by this invention is to combine hot water supply function and heating function, and heat hot water for hot water supply near faucet equipment using heating medium. The purpose of the present invention is to provide a miniaturized heating and hot water supply terminal device that can perform the following functions.

(Means for solving the problem) A heating circulation pipe that connects both ends to the central heating heating circulation circuit, the pipe head to a hot water source or water supply source, and a water faucet to the pipe end. A hot air heating device is provided with a heat exchange section configured by contacting and communicating the above-mentioned two pipelines with each other via a number of fins, and a hot air heating device in which the heat exchange section serves as a heat radiating section; A hot air drying device is provided which extracts a portion of the warm air from the wind heating device and supplies this hot air separately from the hot air heating device.

(Function) Therefore, hot water or water is introduced into the hot water supply pipe from the hot water supply source or the water supply source and supplied to the faucet equipment, and the heating circulation pipe is inserted into the hot water supply pipe. In the heat exchange section, it is heated by the central heating heating medium introduced into the heating circulation pipe and made to flow, and in the case of hot water, it compensates for the heat dissipated on the way, and in the case of water, it is heated to boil the water. On the other hand, the hot air heating device generates hot air using the heat exchange section as a heat radiating section, and the hot air drying device draws out a part of the hot air and generates hot air separately from the hot air heating device. supply.

(Example) Hereinafter, an example of the present invention will be described based on the drawings.

In the figure, 6 is the casing of terminal A, and hot water supply pipe 2
and a heating circulation pipe 1 are installed inside.

The hot water supply pipe 2 has one end protruding from the lower part of the casing 6 and the other end protruding from the upper part of the casing 6, with a hot water supply pipe connection part 7 at the lower end and a faucet fixture 8 at the upper end. establish.

Further, a cylindrical hot water storage section 9 is provided in the middle of the hot water supply pipe 2 in parallel with the hot water supply pipe 2a piped to the lower part of the casing 6, and several hot water storage sections 9 are provided between the lower surface of the hot water storage section 9 and the hot water supply pipe 2a. The contact part 1 is provided with a bypass pipe 10.
Form 1.

The heating circulation pipe 1 is located behind the hot water supply pipe, with both ends of the outgoing pipe part 1a and the return pipe part 1b protruding from the side surface of the casing 6, and a heating circulation circuit is provided at each end. A connecting portion 12 is provided, and a heating contact portion 1c is provided in the middle of the pipe so as to be parallel to the contact portion 11 of the hot water supply pipe 2.

The heating contact portion 1c is formed in a spiral or meandering shape, and is connected to the contact portion 11 of the hot water supply pipe 2 arranged in parallel.
A large number of fins 13 are connected in contact with each other, thereby forming a heat exchange section 3 that transfers heat to the hot water supply pipe 2 of the heating circulation pipe 1.

The heat exchange section 3 exchanges heat between the two pipes 1 and 2, and serves as a common heat dissipation section for a hot air heating device 4 and a hot air drying device 5, which will be described later. A fan 15 for blowing air from the warm air heating device 4 is provided.

The hot air heating device 4 has a hot air outlet 16 on the front plate 6a of the casing 6 in front of the heat exchange section 3.

On the other hand, the blowing port 17 is formed by drilling a large number of holes in the front surface of an air supply chamber 18 provided by partitioning the inside of the casing 6 behind the heat exchanger 3. 18 and is attached to the side of the casing 6.

The hot air drying device 5 blows out the warm air generated by the hot air heating device 4 and blows it from another air outlet 21a, and includes a hot air supply box 21 having a small fan 20 built in on the upper surface of the casing 6. The box 21 and the air supply chamber 18 are connected by a connecting pipe 22, and the box 21
A ventilation port 21a is provided at the top.

The above-mentioned faucet device 8 is a mixer faucet with hot water and hot water, and the hot water supply pipe 2 is connected to the hot water side, and the water supply pipe 23 that connects to a water supply source is connected to the water side.

Thus, the heating and hot water supply terminal device A is used by connecting the heating circuit 1 to the heating circuit 24 in the central heating system and connecting the hot water supply pipe 2 to a hot water source or a water supply source. For example, as shown in Figure 4, it is installed in a toilet to heat the toilet, and the hot water projected from the faucet 8 is used for washing hands and private parts, and also to warm wet hands and private parts. It is dried using an air dryer 5.

Note that the installation location is arbitrary, and the purpose of using the hot water can also be arbitrarily determined depending on the installation location.

Furthermore, this terminal device A can also be installed by being incorporated into a washbasin, a wall panel of a building, etc.

(Effects) Since the present invention has the above configuration, it has the following advantages.

(1) Since the heating medium of central heating is used to heat the hot water for hot water supply near the faucet equipment, large-scale piping that constantly circulates the hot water for hot water supply is not required. Even if you do not do this, your faucet appliances will always or immediately be supplied with hot water.

Also, it is convenient because you can perform tasks such as washing and drying continuously at the same time as heating.

(2) Since one terminal unit has three functions: heating, hot water supply, and drying, there is no need to install separate piping for each, and construction is simple, and heat exchange between heating circulation pipes and hot water supply pipes is possible. The section is used as the heat radiating section of the hot air heating device, and a part of the hot air from this hot air heating device is drawn out and supplied separately from the hot air drying device, so the heat exchange section is used as the heat radiating section. , it is possible to significantly downsize the main body of the container, and thus it is possible to be compact while still having hot air heating and hot air drying functions, and it can be installed in narrow spaces such as toilets.
