Description

[Detailed description of the invention] The present invention relates to a hot water boiler that can be freely selected between wood-fired and oil-fired types.

In the conventional hot water boiler of this kind, as shown in Fig. 1, the wood-fired door a and the oil-fired door A are pivotally mounted on the left and right sides of the fire opening, respectively.
One of the doors a and b was closed and the other was open, allowing the user to freely select between a wood fire and an oil fire.

However, since the doors a and b open and close in both left and right directions, a large installation space is required for the hot water boiler C, which has the disadvantage that it must be installed sufficiently away from the side wall d as shown in the figure. If it becomes necessary to switch to an oil-fired oven while wood-fired, the switching process is not only troublesome, but there are also many accidents where people get burns on their arms, etc. when swinging the hot wood-burning door a towards them. Was.

The purpose of this invention is to solve these conventional problems, and its features are that the inner door and outer door can be stacked on one side of the frame around the fire pit, and can be swung open and closed in the same direction on the left and right. A small window that can be opened and closed is attached to the inner door, and firewood can be burned with the inner door closed and the outer door opened, and a burner is attached to the outer door as described above. The flame tube of the burner is inserted through the small window of the inner door in an open state, and oil can be drained when both the inner and outer doors are closed.

Hereinafter, the present invention will be explained in detail based on the illustrated embodiments.

In Figs. 2 to 6, 1 is a box housing the boiler main body, and a frame 2 around the fire opening is provided at the lower part of the front face 1a, and an inner door is provided on one side of the frame 2 around the fire mouth. 3 and outer door 4
are pivotally supported by a common support shaft 5.

Moreover, the inner door 3 and the outer door 4 are allowed to overlap each other as shown by the solid line in FIG. 2, and are pivotally supported on the fire opening surrounding frame 2 so as to be able to open and close in the same left and right directions as shown by arrows A and B.

As shown in FIGS. 3 and 6, the inner door 3 is provided with a small window 6 that can be opened and closed.

That is, the slide plate 7 is attached to the opening 9 with the mounting member 8 so that it can slide left and right, and the left and right bent portions 7a and 7b of the channel-shaped slide plate 7 are hit with a poker or the like to slide it left and right. The small window 6 is moved to adjust the opening/closing degree of the small window 6, and serves as an air volume adjustment mechanism when burning firewood, which will be described later.

3 and 6 illustrate a case where the inner door 3 is in a closed state and the outer door 4 is in an open state, and this is a state in which firewood can be burned.

That is, when burning firewood, with the inner door 3 open, firewood is introduced into the boiler main body 1 through the opening of the fire spout surrounding frame 2 and ignited.
After that, the inner door 3 is closed.

A burner 10 is attached to the outer door 4, and the outer door 4 is provided with a burner mounting seat 12 having a hole 11 as shown in FIG. 4, and the outer door 4 in the state shown in FIG. Attach the burner 10 to the flame tube 1 of the burner 10 as shown in Figure 3.
3 is inserted inward from the hole 11 and protrudes, and the slide plate 7 of the small window 6 is slid to the right to open the small window 6, and the flame tube 13 of the burner 10 is inserted through the small window 6. The outer door 4 is superimposed on the inner door 3 so as to form a penetrating shape, and both the inner and outer doors 3, 4 can be closed as shown by the solid line in FIG. 2 and FIG. 5 to allow oil pouring.

The fire outlet surrounding frame 2 has a rectangular shape when viewed from the front, and the inner and outer doors 3 and 4 are pivotally supported in the lower half thereof, and another door 14 is provided in the upper half by swinging to open and close around a support shaft 15. The two supporting shafts 5, 15 are arranged on the same side of the surrounding frame 2, and the three doors 3, 4, . 14 opens to the same side.

(Figure 3 shows the state with the door 14 removed.

) Then, by opening the inner and outer doors 3゜4 in the lower half and further opening the door 14 in the upper half, the opening of the fire pit surrounding frame 2 is opened as far as it will go, enlarging the fire mouth and making it possible to burn wood. It is sometimes convenient when burning large objects such as tree roots.

Further, 16 is an ash outlet door provided at a position lower than the surrounding frame 2, which can be opened and closed freely to take out the ash, and in a specific example, when the flame of the burner 10 is strong, etc.
If the regulating member 17 that prevents the door from opening unexpectedly is fixed to the outer door 4 and the outer door 4 is closed as shown in FIG.
6 from the outside to prevent it from opening.

Although not shown, a normal boiler body is housed inside the box 1, and a smoke exhaust pipe 18, a water supply port 19, and a hot water outlet 2 are installed at the top.
0 and protrudes from the top plate of the box body 1.

21 is an operation panel. Note that the box body 1 may be omitted to expose the boiler body.

According to the illustrated embodiment of the present invention, the inner and outer doors 3°4, the doors 14
and 16 open to the same side, the installation space is small, and it can be installed closest to the side wall 22 of the outer wall of the building as shown in FIG. 2, or other equipment or objects can be placed nearby.

Also, the sliding plate 7 of the small window 6 has a protruding bent portion 7a on the front side.
, 7a can be easily and quickly adjusted by hitting 7a with a poker or the like to adjust the air volume of the firewood fire, and it can also be opened and closed easily and quickly when switching between a firewood fire and an oil fire. , the flame tube 13 of the burner 10 can be taken in and out, which is very convenient.

In addition, each door 3, 4.14 is equipped with a locking device and configured to reliably maintain the closed state, and the ash exit door 16
As described above, the regulating member 17 prevents the burner from opening unexpectedly when in use.

The present invention has the above-mentioned configuration, and effectively achieves the intended purpose.
Garbage and firewood can be burned, which greatly contributes to resource conservation, and since the inner door 3 and outer door 4 open and close in the same direction on the left and right, the installation space is small, which is preferable, and the small window 6. Adjusts the air volume when grilling firewood, and adjusts the flame tube 1 of burner 10 when grilling oil.
3, the structure was simplified.

Moreover, since it is possible to switch to an oil-fired oven in the middle of burning firewood without opening the hot inner door 3, it effectively prevents burns to the arms, etc., and the practical effects of this invention are significant. It can be said that there is.
