Description

[Detailed Description of the Invention] (Industrial field of application) The present invention provides a simulated firewood made of ceramic or the like to resemble firewood in a combustion chamber and produces a flame so that the simulated firewood burns during heating. It relates to a fireplace-type wood-type heater that gives off an atmosphere that looks like it did.

(Prior Art) Conventionally, as a heater of this kind, a pseudo-firewood made of ceramic provided in a combustion chamber and a plurality of burners forming a flame as if the pseudo-firewood was burning from below were provided. It is also known that the number of ignitions of the burner is changed according to the adjustment of the heating capacity setting device of the heater.

(Problems to be solved by the invention) The above-mentioned conventional one can increase or decrease the number of burners to be ignited according to the strength of the setting of the setting device, but when the setting value of the setting device is strong or weak, Since the size of the flame of the burner that continues to burn does not change, the visual change corresponding to the heating capacity is poor, and there is a disadvantage that the sensible temperature and the visual sense do not match.

Such an inconvenience can be solved by providing an automatic control valve for increasing or decreasing the fuel supplied to the burner, but it is not preferable since it becomes expensive and maintenance is troublesome.

It is an object of the present invention to provide a simple means for causing the flames of a plurality of burners to have different sizes and for igniting each burner in order to solve such inconvenience of a wood-type heater.

(Means for Solving the Problem) In the present invention, a wood-burning type heater including pseudo firewood provided in a combustion chamber and a plurality of burners that form a flame as if the pseudo firewood is burning from below In order to achieve the above object, a flame merging device having a vertically inclined passage for merging the flame of one burner with the flame of another burner is provided in front of the flame mouth of the burner. .

It is preferable to connect to the plurality of burners a fuel control device that controls shutoff of fuel to the burners according to a set value of a heating capacity setting device provided in the firewood type heater,
A portion of the flame confluence device facing the burner port of one burner may be cut out in a substantially round shape, and a flame for guiding a part of the flame of the burner in a predetermined direction behind the flame confluence device. It is also possible to provide a guide plate.

(Operation) While the firewood type heater is in use, the burner is ignited, and the flame produces a state as if the simulated firewood in the combustion chamber were burning. Since a flame merging device for merging the flame with the flames of other burners is provided, even if approximately the same amount of fuel is supplied to each burner, part of the flame of one burner moves to another burner, and The burner flame of 1 automatically becomes larger than that of 1.
If the fuel supply to the other burners is cut off, the flames will not merge and the flames of the other burners will become smaller. Therefore, by changing the number of ignitions of the burner according to the set value of the heating capacity of the firewood type heater, it is possible to change the flame to a size similar to the combustion of real firewood, and it is observed from the heating capacity and outside the combustion chamber. A comfortable heating feeling can be obtained by matching the size of the flame that is generated, and the structure is simple and can be manufactured at low cost. The amount of fuel supplied to each burner can be different, and in this case, a large flame and a small flame that do not correspond to the amount of fuel supplied can be generated in each burner.

(Embodiment) An embodiment of the present invention will be described with reference to the attached drawings. In FIGS. 1 to 3, reference numeral (1) is a firewood type heater, and (2) is a firewood type heater ( The shelf plate provided in the combustion chamber (2) showing the combustion chamber of 1)
A plurality of simulated firewoods (3) made of, for example, ceramic resembling firewood are fixed to (2a). A glass plate (4) having a secondary air intake (6) and a wire mesh (5) are provided on the front surface of the combustion chamber (2), and a heat exchanger (7) is provided on the back surface. Further, on the left and right outside of the combustion chamber (2), a storage chamber (9) for other electrical components (8) for combustion control and a storage chamber (11) for the exhaust duct (10) are provided. A through hole (2b) is provided on the shelf plate (2a) below the simulated firewood (3).
And the flame and heat of the two burners (12) and (13) provided in the lower part of the combustion chamber (2) are directed to the upper part of the combustion chamber (2) through the through hole (2b). I did it. One of the burners (12) is, for example, a pipe-type burner with another hole,
(3) is turned into red heat, and the other burner (13) is composed of four nozzle-type burners, for example, as shown in FIG. 4, and the pseudo-firewood (3) is burned by the flame ejected from this. I tried to produce a flame like Taka. In the example shown in FIG. 4, four burners (13a) (13b) (13c) (13d) are arranged on each side of the pilot burner (14) facing the central flame divider plate (15). I decided to do it.

The air that has flowed into the combustion chamber (2) from the air intake (6) for combustion in the burners (12) (13) becomes exhaust gas with a high temperature and passes through the inside of the heat exchanger (7). After being heated, it is discharged to the outside through the exhaust duct (10). The heater
At the bottom of the body (1a) of (1), an air intake (16) equipped with a filter (17) for supplying air to the surroundings of the heat exchanger (7) is formed. The air sent to the periphery of the heat exchanger (7) by the wind fan (19) is heated by the heat exchanger (7) and is heated by the hot air outlet (20) above the front of the combustion chamber (2).
It becomes warm air and blows out.

A fuel control device (21) including a governor (22) and opening / closing valves (23) and (24) is connected to each burner (12) and (13), for example, as shown in FIGS. 5 and 6. Gas fuel is regulated by the governor (22) and distributed to the burner (13) consisting of four on-off valves (23) (24) linked to the heating capacity setting device (26) of the heater (1). When the setting device (26) is set to have a high heating capacity, the two on-off valves (23) (24) are opened together and all the burners (13) are set as shown in FIG. When the ignition is activated and the heating capacity is set to a low level, the on-off valve (23) closes and the half burner
(13b) and (13c) are ignited as shown in FIG.

When the four burners (13) are formed to have the same size and the same amount of gas is supplied, the flames of the burners (13) are made substantially uniform in size, and the setting device (26) is set strongly. The size of the burner flame that keeps burning becomes almost uniform even if it is changed, but a flame confluence device (27) is installed in front of the burner (13) flame port, and the burner flame of one burner is burned by the flame of the other burner. It was made to merge with each other so that the size of the flame could change from large to small.

Details of an example of the flame merging device (27) are as shown in FIGS. 7 and 8, and the groove-shaped passage (28) is opened downward.
A sheet metal longitudinal member with two adjacent burners (1
The passage (28) is provided in front of the flame openings of 3a) and 13b so as to be inclined vertically. If there are four burners (13), the fourth
As shown in the figure, if two flame merging devices (27) and (27) are installed in front of each set of burners, the same amount of gas is supplied to four burners of the same size. When ignited, the burner (13
A part of the flame of (a) (13d) merges with the flame of the burners (13b) (13c), and a large flame (29) (29) can be obtained in the burners (13b) (13c). The flame merging device (27) is equipped with a burner (1
3b) (13c) also serves as a flame transfer member that transfers the flame to the burners (13a) (13d), and the burner (14) provided in the center of the four burners (13) burns the burner ( 13b) and (13c) are ignited, and then the gas that has passed through the flame confluence device (27) from the burners (13a) and (13d) is ignited, and the burners (13a) and (13d) are ignited. Also, when the gas fuel to the four burners is different, for example, when the amount to the burners (13a) (13d) is reduced and the amount to the burners (13b) (13c) is increased, the flame confluence is increased. apparatus
Due to the action of (27), a small flame less than the gas amount supplied to the burners (13a) (13d) is generated, and the burners (13b) (13d)
In c), it is possible to generate a flame larger than the amount of gas supplied to it.

One end of the passage (28) of the flame merging device (27) is provided in contact with the flame of the burner (13a) (13d) on the flame supply side, and the other end of the burner (13b) (13c) on the flame merging side. Although it is provided slightly apart from the flame, if the one end is linear, the flame shape of the burners (13a) (13d) will be lost when it contacts the flame, and a converged flame like a candle flame will be obtained. Since the burning feeling of calm wood disappears, a substantially round notch (30) as shown in Fig. 8 is formed at the one end, so that a convergent and convergent flame is supplied at the time of merging. Side burner (13a) (13d)
To occur. In addition, the substantially round notch (30) is
Even when the flame merging device (27) is used to transfer the flame when the burner is ignited, the flame shape of the burner on the fire source side is not lost, so that a clean converged flame can be formed.

The pseudo firewood (3) provided in the combustion chamber (2) is colored and piled up like real firewood, but the burner (1
When the flame of 3) touches, soot adheres and discolors, and the firewood-likeness is lost. It was thought that this inconvenience could be solved by adjusting the direction of the burner (13) and installing it so that the flame could pass through the multiple simulated firewood (3),
The space between the simulated firewood (3) is small, and for example the burner (1
If 3) is installed in an inclined manner, when the ambient temperature is sufficiently warm, even if the flame extends upward due to the draft as shown in a of Fig. 9, even when the ignition is in the initial stage, etc. When the ambient temperature is low, the phenomenon of extending in the gas ejection direction occurs as in b. Taking this fact into consideration, the burner (13) should be oriented in a narrow space where many devices and members are installed. It is not easy to adjust, for example, when four burners (13) are provided as shown in FIG. 4, the burner (13
In (a) and (13d), it was difficult to adjust because of the installation position of the simulated firewood (3). Therefore, a flame guide plate (31) is provided upright from the flame merging device (27) behind the flame merging device (27), and the flame of the burner (13a) (13d) on the flame supply side is combined with the guide plate (31). With this, the artificial firewood (3) is guided in a predetermined direction so as not to touch it, thereby eliminating the difficulty of adjusting the direction of the burner.

The operation of the illustrated embodiment of the present invention will be described.
When the heating capacity setting device (26) of (1) is set weak, the on-off valve (23) of the fuel control device (21) is closed and the on-off valve (24) is opened,
As shown in FIG. 6, the burner (12) and the burners (13b) (13c) are ignited, and the pseudo-firewood (3) is red-heated by the heat of the burner (12).
The flame from the burner (13) erupts from between (3) as if it were burning. When the setting of the setting device (26) is made strong, the on-off valves (23) and (24) are both opened and the burner (12) and all of the four burners (13) are ignited. In this case, the burner (13a) ( 13d)
Part of the flame of the burner merges with the flame of the burners (13b) (13c) through the passage (28) of the flame merging device (27) (27), and a larger flame than when it is set weak is the simulated firewood (3 ), A large and small flame can be revealed according to the strength of the setting, and the heating feeling becomes comfortable.

(Effects of the Invention) As described above, according to the present invention, a vertically inclined passage that joins the flame of one burner with the flame of another burner is provided in front of the burner flame port that forms the flame of the simulated firewood. Since the flame merging device is provided, it is possible to easily and inexpensively increase or decrease the flames of the plurality of burners, and a comfortable heating feeling can be obtained. When the structure of claim 3 is adopted, the burner transfers from one burner to another burner. When this is done, the flame of the burner of No. 1 is not chipped, and there is an effect that a clean flame can be obtained.
