Description

[Detailed Description of the Invention] The present invention relates to a gas burner flame nozzle position adjustment device, and more specifically, the present invention relates to a gas burner flame nozzle position adjustment device, and more specifically, for example, a union joint connects the gas conduit and the bent part of the flame nozzle tube provided with the flame nozzle in a sideburns stove, etc. The union joint should be easily loosened with a handle, so that even when the device is in operation, it can be attached to either the inner pot or the copper pot in the case of a buckwheat stove, as needed. This invention relates to a gas burner flame port position adjustment device that allows the position of the port to be changed.

Conventionally, for equipment that uses gas burners,
The flame nozzle is fixed in a constant state in the combustion chamber of the device, and although it is possible to adjust the combustion intensity, it is not possible to change the position of the flame nozzle during use if necessary due to the configuration of the device. , it had the disadvantage of not being able to do that. Furthermore, even if it is possible to make changes, it is necessary to temporarily stop using the device and reassemble it, making it inconvenient for the user to make frequent changes. The drawback is that it is possible.

The need to change the position of the flame port of a gas burner arises, for example, in a soba stove used for commercial purposes. Soba ovens generally have a copper pot around the central combustion chamber, and a medium pot placed in the center. It is usually separated into two chambers and stores boiling water; one is used to boil the tampo, and the other is used to warm the bowl or replenish hot water to the inner pot. Since the inner pot is used to boil soba, udon, etc. as soon as needed, it is necessary to keep the water boiling almost all the time, and the Bunsen burner as a secondary burner can be lit, and the Blast Bart can be used as the main burner as needed. However, if the hot water in the inner pot gets low or dirty, it needs to be replenished or replaced. By the way, this need for replenishment and replacement usually occurs when there are a lot of customers and there is a rush of orders, and at times like these, it is necessary to refill water, throw away dirty water, and refill it with fresh water. If they were to boil the noodles, they would have to stop serving buckwheat noodles during that time, which is unacceptable for business purposes. Therefore, in such cases, pump the pre-heated hot water in the copper pot toward the inner pot.
The boiling process can be continued immediately. In this case, water is automatically replenished into the copper pot, but the copper pot is generally heated using residual heat or reflected heat from heating the inner pot.

Therefore, from daytime to evening when there are always customers, the hot water in the copper pot is sufficiently hot, if not boiling, due to residual heat and reflected heat, and does not cause any inconvenience during work. At times, there is the disadvantage that it cannot be completely heated up by mere residual heat or reflected heat.
In addition, in shops with few customers, the water in the inner pot is not always boiling, but when customers come, the inner pot is rapidly heated to a boiling point, so the water in the copper pot is almost completely cold, which is extremely inconvenient for work. There was a problem that it was bad. Therefore, in such a case, it is necessary to forcibly heat the copper pot side as well, and for that purpose, the blast burner, which is the main burner, is installed opposite to both the inner pot side and the copper pot side. An apparatus having a gas burner whose position can be changed even during operation has been desired.

In view of the drawbacks and needs of the conventional device described above, the present invention has an extremely simple configuration and allows the position adjustment of the gas burner flame port to be easily changed and set as needed during operation of the device. The purpose of the present invention is to provide a device, the gist of which is a flame port tube having a flame port provided at one end, a bent portion formed at the other end, and a middle portion movably supported on a frame; a gas conduit disposed on the gas supply pipe side such that its end is opposite to the end of the bent portion, and a union joint that connects the bent end of the flame port tube and the gas conduit end; , consisting of a tightening handle fixedly attached to the union nut of the union joint, and a position adjustment handle fixedly attached to the bent end side of the flame mouth tube, and the tightening handle is operated. The gas burner flame port position adjustment device is configured to move the flame port tube relative to the frame and change the position of the flame port by loosening a union joint and operating a position adjustment handle.

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

FIG. 1 is a partially cutaway cross-sectional front view of the main parts of an embodiment of the present invention, in which 1 is a gas conduit installed on the gas supply pipe side, and 2 is screwed into the gas conduit 1. The joined elbows form the gas conduit ends. Reference numeral 3 designates a flame port tube, and although not shown, a flame port plate is provided at one end with a large number of small holes for gas ejection and air intake holes, and a bent portion of the flame port tube 3 is provided at the other end. The adjusting elbows 4 are screwed together, and the intermediate portion is supported by a method not shown in the apparatus frame so as to be movable in the front and back directions of the paper in FIG. 4a is a position adjustment ring that fits into the other end of the adjustment elbow 4 relative to the joint with the flame tube 3 and is fixed, for example, by welding, and 5 is a position adjustment ring whose one end is screwed into the position adjustment ring 4a. It's a handle. A union joint 6 is composed of a union screw 7, a union collar 8, and a union nut 9. The union screw 7 has one end screwed into the adjusting elbow 4, and the union collar 8 has one end screwed into the elbow 2. , the threaded portion and collar portion of each other end are threaded and engaged with a union nut 9, thereby connecting both elbows 2 and 4. 10 is a tightening handle whose one end is screwed into the union nut 9; 11 is a ring-shaped gasket disposed between the union screw 7 and the union collar 8;

Therefore, according to the device for adjusting the position of a gas burner flame nozzle according to the present invention, the flame nozzle tube 3 provided with the flame nozzle plate is set in advance at a predetermined position, and the device is operated. When changing the position, the gas supply to the gas supply pipe 1 is temporarily cut off, and the union nut 9 is rotated to the left by operating the handle 10 to release the close contact between the union screw 7 and the union collar 8. Thereafter, by operating the position adjustment handle 5, the flame tube 3 is swung around the axis of the union joint 6, and the flame port plate is set at the required position. Then, the handle 10 is operated again to turn the union nut 9 to the left to bring the union screw 7 and the union collar 8 into close contact with each other. At this time, the gasket 11 ensures complete sealing. This operation may be repeated as necessary.

This is a perspective view of the main part of the soba stove, which allows various business operations such as boiling buckwheat noodles, boiling in hot water, and washing dishes to be carried out efficiently overall.
Main body 2 that carries the inner pot and performs the functions of storing hot water, etc.
0 and a frame 21 on which the grate, burner, etc. are placed are assembled in a separable manner.

The main body 20 has a space 22 in the center that becomes a combustion chamber.
A copper pot 23 with one chamber for storing hot water is provided around the space 22, and a clamping frame 24 rising from the upper surface of the copper pot 23 is formed on the upper periphery of the space 22. The inner pot 25 (FIG. 3) is placed on the rack. Further, on the upper surface of the copper pot 23, there are copper pot openings 26, 26 at the front for refilling hot water into the inner pot 25, warming a bowl, boiling soup, etc., and at the back thereof. Copper jar openings 27, 27 are open for other uses such as boiling water for soup stock. At the rear of the copper pot, an exhaust port 28 is formed which penetrates from the inside of the space 22 to the outside of the copper pot.
Further, a tank 29 which is internally connected to the copper pot 23 is disposed high above the back surface of the copper pot 23.

The frame 21 has legs on which the main body 20 can be placed tightly, and a grate 30 and a burner block 31 can be installed below the space 22 of the main body 20. 32 is a viewing window, 33 is a control section for the burner block 31, and 58 is a front lid that can open the inside of the frame 21. burner block 3
1 is fixedly disposed on a substrate 34 fixed to the frame 21. Reference numerals 34a, 34b, and 34c are cylindrical fitting fitting portions formed integrally with the substrate 34, and each of the fitting fitting portions 34a to 34c includes:
Adjustment screws 35 that can be inserted and removed at three equal positions on the circumference of each part
are screwed together, and each screw 35 is provided with a locking nut. 37 is a bracket attached to the substrate 34, and 38 is a main pipe whose both ends are fixed to the bracket 37 and connected to a gas pipe via a union joint 39, forming three branch pipes. Reference numeral 40 indicates a blast burner handle connected to the central branch pipe, 41 and 42 indicate a Bunsen burner handle connected to the left and right branch pipes, and 43 indicates a gas conduit, one end of which is connected to the adjustment screw 35 in the mounting fitting part 34a. The other end is bent downward and connected to the blast pipe 46 from the blast motor 45 via a governor 44a and a solenoid valve 44b, and is finally connected to air. A gas conduit 47 for guiding the forcibly mixed mixed gas of the present invention, a union joint 6' similar to that shown in FIG. is installed. 5' and 10' are a position adjustment handle and a tightening handle attached to the adjustment elbow 4', union joint 6', respectively. Although not shown, nozzles having threads formed on their outer peripheries are connected and fixed to the cocks 41 and 42, respectively, and dampers 5 are attached to each threaded portion.
1 and 52 are screwed together. Both 53 and 54 are known air mixing tubes that mix gas and air by sucking air into the interior under negative pressure as the gas is ejected from the nozzle, and their outer circumferential diameters are the same as the outer circumferential diameters of the dampers 51 and 52. Each end has three adjustment screws 35 in the mounting fitting portions 34b and 34c.
It is tightened and fixed in a state where the centering with the nozzle is done by
6 are respectively disposed, and their ends are supported by the receiving parts of the frame of the frame base 21.

Therefore, the buckwheat oven with the above-mentioned configuration is made with copper pot 2 in advance.
3. After appropriately supplying water to the inner pot 25 and tank 29, the pilot burner 57 installed at the mouth of each flame port plate
When the burner is ignited and then the respective pots 41 and 42 are opened, the gas ejected from the flame ports 55 and 56 of the Bunsen burner is combusted and the required amount of water is boiled. In addition, when it is necessary to boil water rapidly at the start of work in the morning or when necessary in winter, the control unit 33
When you operate the knob, first the blast motor 45
operates to blow air, and when the knob is further rotated, the solenoid valve 44b operates, and the governor 44a
Since gas at a constant pressure is sent to the gas conduit 47 through the gas conduit 47, a forced mixture of gas with air is ejected from the flame port plate 48, and powerful combustion takes place.

By the way, as mentioned above, the hot water in the copper pot 23 is usually heated by the Bunsen burners 55, 56,
Boiling is done by indirect heating such as reflected heat from the blast burner 48, but this heating works well from midday to evening when there are always customers, and the water in the copper pot never boils. Even if it is not heated, it can be kept hot to the extent that it does not cause any inconvenience during work. However, for example, at the start of work in the morning or at low temperatures in winter, the hot water in the copper pot may not be completely heated by mere residual heat or reflected heat. The water in the pot is not kept boiling all the time, and when guests arrive, the pot is rapidly heated to a boil, so the water in the copper pot may get colder. Therefore, in such a case, the blast burner's flame plate 48 should be moved to the side of the copper pot at the beginning of the operation to forcibly heat the copper pot, or the position of the blast burner's flame plate should be changed in advance during winter. Rather than installing it completely facing the inner pot, it is necessary to install it slightly toward the copper pot so that the hot water in the copper pot can be used as hot water whenever necessary.
Therefore, in such a case, as in the case explained in FIG.
Loosen the union joint 6' by operating the button, and in this state move the handle 5' to change the position of the flame port plate 48. For example, if you turn the handle 5' to the left from the position shown in Figures 3 and 4, Flame vent plate 4
The position 8 is also moved to the left to take a position where the copper pot 23 can be directly heated, so if the handle 10' is operated again at the appropriate position and the union joint 6' is tightened, the copper pot can be directly heated. It can be considered as a state. In order to return the flame port plate 48 to its original state, the flame port plate 48 may be reversely moved and fixed by operating the union joint 6' in the same manner as described above.

Note that the present invention is not limited to the above configuration; for example, the gas pipe provided with the union joint may be directly connected to the gas supply pipe (blast burner), or may be separated from the nozzle in the air mixing section. The bending portion may have any length, and the position adjustment handle may be installed at any position.

As described above, the device for adjusting the position of the gas burner flame nozzle according to the present invention has a simple structure using a union joint, and allows the position of the flame nozzle to be easily changed whenever necessary during operation of the device. As a result, the device using the device of the present invention has improved functions in use and is extremely convenient.
