Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a gas pipe connection structure for a device that is installed in a kitchen together with other kitchen devices such as a sink and a cooking table, and that incorporates a cooking device.

Structure of a conventional example and its problems A conventional gas stove stand with built-in cooking utensils, for example, will be explained based on FIGS. 1 to 6.

FIG. 1 is a general external perspective view of a gas stove stand with a built-in high-frequency heating device. In FIG. 1, a pipe cover 4 and a back guard 5 are provided behind a top plate 3 on the upper surface of a cabinet 2 containing a cooking device 1 to protect the indoor wall surface from exhaust heat and water vapor from the equipment. Above piping cover 4
There is a space for the exhaust port from the cooker 1 and a space for the gas pipe 6, and on the surface there is a cover 7 for the exhaust port of the cooker 1, a cover 8, a hose end connection port 9, and a space for the gas pipe 6. A removable gas pipe hook 10 is provided. The top plate 3 can be used as a cooking table, or a gas stove or the like may be placed thereon and gas supply may be controlled via the cooker 8 and hose end 9.

Further, around the front of the cooking device 1, there is a front frame 11 that covers the cooking device 1 after it is assembled into the cabinet 2.

A lid 13 is attached to the lower part of the front frame 11 so as to be openable and closable in order to operate the base cover 12.

Next, we will discuss gas piping.

Inside the cabinet 2, there is a pipe 6 as shown in Figure 2.
There is. As shown in FIG. 3, a gas pipe 15 is raised from the shaded area 14 in FIG. The gas pipe 6 is branched in the middle, and one side is connected to Kotoku 8,
The other one is designed to be able to supply gas to the cooking device 1. A gas connection pipe 16 is arranged from the cooking device 1 as shown in FIG.
The screws 20,
21 is shut off to prevent gas leakage.

During assembly or service, the cooking appliance 1 is assembled as shown in FIG. 3 without the front frame 11 attached.
The space between the gas pipe 6 and the gas connection pipe 16 in the space between the gas pipe 6 and the gas connection pipe 16 is narrow and difficult to install and remove.
In some cases, you may forget to install the O-ring, or it may be installed incompletely (it remains twisted or broken).
In some cases, the defective work was discovered during the gas leak inspection during the inspection.

Therefore, as shown in FIG. 6, a flanged O-ring 22 is sometimes used. In this case, as shown in FIG. 7, since the O-ring 22 has a flange having an outer shape that is approximately the same as the outer shape of the flanges 17 and 18, the presence or absence of the O-ring can be confirmed even after installation. However, even with this method, there was no way to check whether O-rings with slightly different dimensions were being used optimally after installation.

OBJECT OF THE INVENTION The present invention solves the above-mentioned conventional drawbacks.
The purpose of this invention is to improve the sealing structure of O-rings, etc. used in gas piping connections such as gas stove stands with built-in heating cookers.

Structure of the Invention In order to achieve the above object, the sealing structure of the O-ring or the like used in the gas piping connection part of the gas stove stand with a built-in heating cooker of the present invention, rather than the flange part of the gas piping connection part, is This is a configuration in which the O-ring protrudes, and the protruding part displays numbers and symbols indicating the unique characteristics of the O-ring (for example, the diameter of the pipe to be used, the inner diameter and thickness of the O-ring, etc.), and it is easy to install. This has the effect of making it easy to confirm whether the correct O-ring is being used afterward, and providing equipment that is free from gas leakage accidents.

DESCRIPTION OF EMBODIMENTS An embodiment of the present invention will be described below based on the drawings.

The same members as in the conventional example will be described using the same drawings and the same numbers.

In FIG. 1, which is a general external perspective view of a gas stove stand with a built-in high-frequency heating device, behind the top plate 3 on the upper surface of the cabinet 2 containing the cooking device 1, there is a piping cover 4 and heat exhaust from the equipment. Back Guard 5 to protect indoor walls from water and water vapor
is provided. The piping cover 4 has a space for the exhaust port from the cooking device 1 and a space for the gas piping 6, and the surface has a cover 7 for the exhaust port of the cooking device 1, a cover 8, and a hose end connection. Port 9, removable gas pipe hook 10 for rubber piping
has been established. The top plate 3 can be used as a cooking table, or a gas stove or the like may be placed thereon, and gas supply may be controlled via the cooktop 8 and hose end 9.

Further, around the front of the cooking device 1, there is a front frame 11 that covers the cooking device 1 after it is assembled into the cabinet 2.
There is.

A lid 13 is attached to the lower part of the front frame 11 so as to be openable and closable in order to operate the base cover 12.

Next, we will discuss gas piping.

Inside the cabinet 2, there is a pipe 6 as shown in Figure 2.
There is. As shown in Fig. 3, the gas pipe 15 is launched from the shaded area 14 in Fig. 2 (floor surface, rear wall surface), and on the way,
A base tank 12 is provided and the gas piping 6 of the cabinet 2 is connected to it. The gas pipe 6 branches in the middle,
Gas can be supplied to one side of the cooker 8 and the other side of the cooker 1. A gas connection pipe 16 is arranged from the cooking device 1 as shown in FIG. 3, and the connection to the gas pipe 6 is made through flanges 17 and 18, respectively, as shown in FIG. As shown in FIG. 9, screws 20 and 21 are secured via O-ring attached flanges 23 to prevent gas leakage.

The flanged O-ring 23 has a flange portion 17,
From 18, a protruding portion 24 is provided, and numerical values and symbols indicating unique characteristics of the O-ring, such as the inner diameter of the pipe to be used, the inner diameter and thickness of the O-ring, etc.
Indicates the part number, etc. of the device.

According to this embodiment, even after installation, it is possible to check if the correct O-ring is used or if there is a protruding part that is integrated with the O-ring in the part of the gas pipe that protrudes from the flange part. ,
By looking at the symbols and numerical values, you can check whether they are the prescribed symbols or numerical values, and have the effect of not only checking if you have forgotten to insert an O-ring, but also checking whether the O-ring is set correctly and whether it is twisted or broken.

Effects of the Invention As described above, according to the present invention, the following effects can be obtained.

(1) Since the sealing material protrudes beyond the gas piping connection flange, it is easy to check if sealing material such as an O-ring has been left in, even after assembly, and gas leakage can be prevented.

(2) Since it is the same size as the gas piping connection flange and protrudes, even after tightening the flange, check whether the sealing material such as O-ring is twisted or cut. It can be easily identified when viewed from the side of the flange, and gas leakage can be prevented.

(3) The gas piping connection flange part protrudes beyond the flange part, and numbers and symbols are written on the protruding part, so even after tightening the flange, refer to the numbers and symbols written on the protruding part when installing. It can be determined whether the correct O-ring or other sealing material is being used, and inspections can be carried out at the time of shipment or service replacement with peace of mind, making it possible to provide safe equipment.
