Description

Portable hot water boiler {PORTABLE HOT-WATER BOILER}

The present invention relates to a portable hot water boiler, which is a boiler for supplying hot water from the outdoors to the inside of the mat. It has a simple structure and excellent thermal efficiency, and in particular, it cools the make-up water returning to the heating tank to rapidly expand the inside of the heating tank. It relates to a portable hot water boiler that can prevent stoppage of operation and facilitate circulation.

In general, portable hot water boilers are used for the purpose of keeping warm by continuously supplying hot water heated to the inside of the mat in outdoor activities, including mountaineering, fishing, and camping.

Such a hot water boiler includes the feed water valve structure of a portable hot water boiler of Publication No. 20-2009-0005981 (published on June 17, 2009), Utility Model Publication No. 20-0193222 (published on August 16, 2000). ) of "Portable Hot Water Boiler", and in this prior art, the hot water in the heating tank heated by the burner circulates the mat with the expansion force, flows into the water tank, and is supplied to the heating tank again.

However, the portable hot water boiler according to the prior art has a problem in that it does not operate smoothly as it is circulated by the expansion force of the hot water while depending on no power. That is, if the hot water heated in the heating tank circulates to the mat and flows into the water tank and is supplied into the heating tank in an uncooled state, the inside of the heating tank is continuously heated and the pressure is high, so the supply water is not filled and the check valve is closed. It is discarded, and the supply of make-up water is not smooth or the operation is impossible due to overheating.

1 shows the internal structure of a portable hot water boiler according to an embodiment of the present invention, and FIG. 2 shows a state in which the portable hot water boiler according to the present invention is used.

As shown in the figure, the portable hot water boiler according to an embodiment of the present invention includes a case 40 in which a burner is installed, a heating tank 10 with an inside sealed above the burner, and input into the heating tank. A hot water supply pipe body 30 connected to a mat having an induction pipe 31, a water tank 20 having a space above the heating tank and having a lid, and installed under the water tank to recover hot water circulating the mat The hot water recovery pipe body 32, the make-up water inlet pipe body 34 connected to the induction pipe introduced into the water tank and mounted to the lower part of the water tank, the make-up water supply pipe body mounted on the heating tank upper part and connected to the inside of the heating tank (36), the cooling device 60 is provided between the connecting hoses (34a, 36a) connecting between the make-up water inlet pipe and the make-up water supply pipe.

In addition, the cooling device 60 is connected to the heating tank 10 and the water tank 20 by introducing the connecting hoses 34a and 36a into the cooling water tank 62 storing the cooling water.

The above is described in more detail as follows.

First, as shown in FIG. 1, the main body 100 constituting the portable hot water boiler is equipped with a burner 50 from the bottom, has a heating tank 10 and a water tank thereon, and has a case 40 on the outside. have.

The case 40 is to protect the boiler and to protect the flame of the burner from the wind, and may be configured in a cylindrical or polygonal shape, and has a burner fixing plate 52 on the lower portion of which the burner 50 can be attached and detached. .

In addition, the case has a hole 42 formed in the front middle portion to expose the tubular bodies to be described later and to connect the external mat and the cooling device.

And the heating tank 10, the inside of which is sealed by the sealing cap 12 on the upper part of the burner 50, is mounted inside the case 40 through a predetermined bracket 14.

Thereafter, the hot water supply pipe 30 is mounted on the heating tank 10, and the hot water supply pipe 30 is connected to the outside of the mat 1 by the connecting hose 30a to the inflow path 1a. , an induction pipe 31 mounted to pass through the sealing cap 12 into the inside is put into the heating tank 10 .

Next, a post 24 is installed on the heating tank 10 and a water tank 20 is mounted with a predetermined space therebetween.

The water tank 20 can be filled with water while having a lid 22 that opens and closes upward, and a hot water recovery pipe 32 is mounted at the lower portion.

The hot water recovery pipe body 32 is for recovering the hot water that has circulated the mat 1, and is connected to the discharge path 1b of the mat 1 through a connecting hose 32a from the outside, and the other side is inside the water tank. connected

At this time, the hot water return pipe body 32 is equipped with a check valve 33 inside the water tank to prevent the reverse flow of hot water.

In addition, a make-up water inlet pipe 34 is mounted on the lower portion of the water tank to supply hot water stored in the water tank to the inside of the heating tank 10 .

The make-up water inlet pipe body 34 is mounted on the bottom surface of the water tank, the inner end is connected to the inside of the water tank by an induction pipe 35, and the outer end is a cooling device to be described later by a connecting hose (34a) ( 60) and then connected to the heating tank (10).

At this time, in order to introduce the make-up water flowing out through the make-up water inlet pipe 34 into the heating tank, a make-up water supply pipe 36 is mounted on the top of the heating tank 10, and the guide pipe inside the water tank 20 A check valve 37 is installed at the end of (35) to prevent backflow of hot water in the heating tank.

And, the outer end of the make-up water supply pipe body 36 is connected to the make-up water inlet pipe body by a connecting hose (36a).

On the other hand, a predetermined cooling device 60 is provided between each of the connecting hoses 34a and 36a connecting the make-up water supply pipe body 36 and the make-up water inlet pipe body 34 .

The cooling device 60 is provided with a cooling water tank 62 storing the cooling water 64 as shown in FIG. 2, and has nipples 66 and 68 for mounting the above-described connecting hoses 34a and 36a. have.

Therefore, the cooling device 60 is to cool the make-up water flowing out of the water tank and put it into the heating tank 10, and the cooling device may be an air cooling type in addition to a water cooling type.

On the other hand, the connecting hose 30a between the hot water supply device 30 and the mat may be provided with a normal temperature control device as necessary to maintain a constant temperature.

As such, the portable hot water boiler having the cooling device 60 operates as follows.

First, when the water inside the heating tank 10 is heated by the burner 50, it is supplied to the mat 1 through the induction pipe 31 and the hot water supply pipe 30 by the expansion force, and the mat is heated. Thereafter, the hot water circulated through the mat is introduced into the water tank 20 through the hot water recovery pipe 32 .

As the hot water moves to the water tank 20 in this way, a vacuum pressure is generated inside the heating tank 10, and as the check valve 37 is opened by the negative pressure of the pressure, the hot water inside the water tank is used as supplementary water in the heating tank ( 10) is returned.

At this time, the make-up water has a certain degree of heat, and when it returns to the heating tank 10 as it is, the vacuum pressure is released and the check valve 37 is closed. Therefore, the heating tank is circulated to the mat in a state where it is not completely filled, so it does not work smoothly and the boiler stops.

Accordingly, in the present invention, as the make-up water is sufficiently cooled through the cooling device 60 and then flows into the heating tank 10, the vacuum pressure inside the heating tank 10 is maintained for a longer time, and the hot water in the water tank flows into the heating tank. enough to be filled.

Then, the hot water heated by the burner expands again and continues to circulate supplied to the mat.

Although the present invention has been described with reference to the embodiments shown in the accompanying drawings, which are illustrative and not limited to the above-described embodiments, those of ordinary skill in the art will realize that various modifications and equivalent embodiments are possible therefrom. point can be understood.
