Description

[Detailed explanation of the idea] This invention relates to the improvement of a commercial gas boiler.

Conventionally, in commercial gas boilers, the main container in which the gas burner is installed is supported by a support body, and
It is well known that a kettle body is housed in the main body container and the kettle body is heated by the gas burner. Therefore, when this product is installed in a cooking room, etc., piping to the gas burner is also installed, and when that piping is done, a connecting pipe is used to connect the specified gas supply source and the gas burner. It is designed to be buried under the installation floor.

However, with the above-mentioned piping configuration, if a gas leak occurs in the connecting pipe due to rust or fatigue over time, it is difficult to detect the gas leak early because the connecting pipe is under the floor surface, and it is extremely difficult to detect the gas leak early. There is a risk that a dangerous situation may occur, and it is also difficult to maintain and inspect the connecting pipe, and furthermore, the cost required for burying the pipe (installation cost) increases, causing a rise in product costs. In particular, multiple such commercial gas boilers are often installed side by side, and in this case, the above-mentioned risks are high, and furthermore, it takes a lot of time and money to bury them, and it is difficult to connect them to each other from the buried connecting pipes. The branch pipe to the gas burner rises from below the floor, so the length of the pipe is long. Therefore, if there are multiple gas boilers for commercial use, the length of the pipe as a whole becomes considerably long, which also increases the installation cost. There was a problem that caused prices to rise.

Therefore, the purpose of this invention is to provide a gas boiler for commercial use that can detect gas leaks at an early stage and prevent the occurrence of dangerous situations, and that also allows easy maintenance and inspection of connecting pipes and reduces installation costs. There is a cooking pot provided.

An embodiment of the present invention will be described below with reference to the drawings. First, Figure 1 shows a state in which three commercial gas boiling pots are installed in parallel.
In the figures and FIG. 2, reference numeral 1 denotes a support leg, and two-split bearing brackets 2, 2 are attached to the upper left and right sides of the leg 1. Although not shown, the bearing brackets 2, 2 have bearing metal are provided for each. 3 is a main body container, which is rotatably supported by the bearing brackets 2, 2;
For example, three gas burners 4 are disposed in the lower opening of the main body container 3. Reference numeral 5 denotes a rotation mechanism for rotating the main container 3, which is composed of a handle 6, a worm (not shown), a worm wheel 7, and the like. Reference numeral 8 denotes a pot main body, which is detachably housed in the main container 3. 9 is a lid that opens and closes this pot body 8;
A tilting mechanism 11 and an opening/closing mechanism 12 are provided on a column 10 provided at the upper part of the bracket 2, and the tilting mechanism 11 is constructed as shown in FIG. That is, 13 is a base plate, which is provided on the support 10 by a hinge pin 14 so as to be rotatable in the direction of arrow A and the direction opposite to arrow A, and this base plate 13 has an arcuate groove 15 centered around the hinge pin 14. It is formed. Further, 16 is a clamp, which has a threaded part (not shown), and the threaded part is screwed into a nut (not shown) attached to the back surface of the column 10 through the groove 15. By loosening the clamp 16, the base 1
By allowing the rotation of 3 and tightening the board 1.
3 in its rotational position. On the other hand, the opening/closing mechanism 12 has a structure in which a pair of arms 17 are pivotally attached to the upper end of the base plate 13 via a hinge pin 18, and a toggle spring (not shown) is further provided, and the arms 17 are attached to the lid 9. Therefore, the lid 9 is held closed by the opening/closing mechanism 12 as shown by the solid line in FIG. 1, and opened as shown by the two-dot chain line. Clamp 1 of the folding mechanism 11 (shown with chain lines)
By loosening 6, it can be tilted forward or backward (see the dashed dotted lines in Figure 2). In FIG. 1, 19 is a handle attached to the lid 9, and 20 is a control box equipped with a timer 21 and the like. Reference numeral 22 denotes a connecting pipe, which is made of stainless steel and is installed on the leg 1 so as to pass through both supporting legs 1a, 1a of the leg 1, as shown in FIGS. 4 and 5. The connecting pipes 22 in each gas boiling pot are connected to each other by flexible pipes 23, 23 as shown in FIG.
Further, rising piping is provided from each connecting pipe 22, and piping extending to each gas burner 4 is provided from the rising piping portion 24. In the rising piping section 24, 25 is a flexible pipe. Further, among the continuous connecting pipes 22, the right end of the one on the right side in FIG. 1 is used as a connecting port for connecting piping from a predetermined gas supply source. Thus, gas from the gas supply source passes through each connecting pipe 22 to each gas burner 4.
supplied to

Now, according to this embodiment with the above configuration, the following effects can be obtained.

() Since the connecting pipe 22 is installed on the leg 1, unlike the conventional method where the connecting pipe is buried under the floor, the connecting pipe 2
Even if a gas leak occurs in 2, it can be recognized quickly and a dangerous situation can be reliably prevented from occurring.Furthermore, maintenance and inspection such as replacing the connecting pipe 22 can be easily performed, and furthermore, connection pipe burying work can be done easily. This can be made unnecessary and installation costs can be reduced, and the length of the upright piping section 24 can also be shortened, which can also reduce equipment costs. Furthermore, connect the connecting pipe 22 to leg 1.
Since it is integrated with the gas boiler, the connecting pipe 22 can be installed automatically, and the piping work can be simplified in general.

() Furthermore, since the connecting pipe 22 is arranged to span the leg 1, the connecting pipe 22 can constitute a part of the leg 1, and the connecting pipe 22 can constitute a part of the leg 1. This allows for effective use of the connecting pipe 22 and also serves as reinforcement for the leg 1.

() Furthermore, since the connecting pipe 22 is made of stainless steel, rust can be prevented and gas leakage can be prevented as much as possible.

() Furthermore, since the tilting mechanism 11 is provided so that the opened lid 9 can be tilted forward or backward, the lid 9 can be moved to a lower position and the cleaning operation of the lid 9 can be facilitated. .

As is clear from the above description, the present invention includes a support body, a main body container supported by the support body and provided with a gas burner 4, and a kettle body housed in the main body container and heated by the gas burner. A gas boiling pot for commercial use having a gas boiler is characterized in that a connecting pipe for connecting the gas burner and a gas supply source is disposed on the support, thereby preventing gas leakage. It is possible to quickly recognize the situation and reliably prevent the occurrence of dangerous situations, and it also makes it easier to maintain and inspect the connecting pipes, eliminates the need for burying the connecting pipes, and simplifies the piping work itself. It has various excellent effects such as a significant reduction in installation costs.
