Description

[Detailed description of the invention] <Industrial application field> This invention relates to a heating device that can perform stove heating and hot water heating for home use.

<Conventional technology> Conventional heating that uses the exhaust gas and exhaust heat of a stove that emits radiant heat and hot air through combustion to create hot water, and then introduces the hot water into a radiator via a circulation pump for hot water heating. The device is known.

<Means for solving the problem> However, since this system performs stove heating using radiation or hot air and hot water heating at the same time, it is difficult to control the temperature, and in the end, the only way to control the temperature is by adjusting the thermal power, which is inconvenient.

Therefore, in order to solve this inconvenience, in recent years Jikosho
As seen in Publication No. 58-52450, a device has been proposed in which stove heating and hot water heating can be selected, and this device is designed to improve the heat exchange efficiency of the stove heat exchanger during stove heating. In addition to the heat exchanger, it was also equipped with an auxiliary heat exchanger.

However, this conventional type has a structure with an exhaust passage inside the water storage tank, so even when the stove is heating, heat is taken away by the water in the water storage tank, and the heat exchange efficiency is actually not good. Moreover, the structure of the auxiliary heat exchanger was complicated and the cost was high.

<Means for solving the problem> A burner in an outer frame, a combustion chamber communicating with the burner, a stove heat exchanger communicating with the combustion chamber, and a hot water heat exchanger for producing hot water using exhaust gas or exhaust heat. In the heating device, which is connected to a hot water heat exchanger via a radiator and a circulation pump installed on the outside of the outer frame, an exhaust port exclusively for combustion is provided on one side of the stove heat exchanger. The stove heat exchanger is equipped with a hot water exhaust port that is opened in parallel with the hot water exhaust port, and a switching device that opens and closes each exhaust port alternately. A guide tube is installed upright, and a partition plate is extended from the exhaust guide tube to separate the combustion exhaust port and the hot water exhaust port, and the exhaust guide tube also has an exhaust port on the hot water exhaust port side. This relates to a heating device characterized by having an opening.

<Function> To explain hot water heating, the switching device 9 is operated and the combustion exclusive exhaust port 5 is connected to the closing plates 11 and 12 as shown in FIG.
A well-known combustion operation is performed with the hot water exhaust port 6 closed and the hot water exhaust port 6 open.

As a result, exhaust gas or exhaust heat is transferred to the exhaust guide pipe 4.
The hot water is immediately discharged from the exhaust port 8 via the hot water exhaust port 6 → heat exchange chamber 16 → exhaust path 14 → exhaust device 15.

At this time, a hot water heating exchanger 1 is installed in the heat exchange chamber 16.
7 is installed inside, the hot water heating heat exchanger 17 is heated to raise the temperature of the water inside to a predetermined temperature.

Thereby, when the circulation pump 19 is started, hot water is repeatedly circulated through the hot water heating heat exchanger 17 → cistern tank 18 → circulation pump 19 → radiator 20 → hot water heating heat exchanger 17 to perform hot water heating.

At this time, the exhaust gas or exhaust heat does not bypass the stove heat exchanger 3 and is immediately transferred to the heat exchange chamber 1.
6, there is no heat radiation from the stove heat exchanger 3, and there is little heat loss. Therefore, the temperature of the hot water heating heat exchanger 17 is raised to a predetermined temperature in a short time, and the heat exchange efficiency of hot water heating is improved. improves.

Next, in the case of stove heating, the switching device 9 is operated to open the combustion-only exhaust port 5 using the closing plates 11 and 12 as shown in Fig. 3, and the hot water exhaust port 6 is closed. The gas is discharged from the exhaust port 8 of the cylinder 4, largely bypassing the stove heat exchanger 3, and passing through the combustion-only exhaust port 5→exhaust path 14→exhaust device 15.

Therefore, the entire stove heat exchanger 3 is sufficiently heated by the exhaust gas or exhaust heat, and a large amount of radiant heat or warm air is uniformly released to the surroundings.

Also, at this time, the exhaust gas or exhaust heat does not heat the hot water heating heat exchanger 17 at all, and therefore, heat is not taken away by the water and the stove heating can be performed without heat loss, thereby improving the heat exchange efficiency.
