Abstract

PURPOSE:To prevent a rubber hose or a gas cock from deteriorating by providing a cooling fin between a gas supplying main pipe and the rubber hose. CONSTITUTION:The primary piping 13 is heated by conduction of radiant heat from the gas oven 11 to a high temperature. Since the fin section 24 and the groove section 25 which are divided in several sections at the fin joint 14 are large in external circumferential area and small in thickness, heat radiation action works and both the groove section 25 and the fin section 24 are cooled by the low temperature crude gas passing through the gas vent hole 26. The synergistic effect due to the radiation from the external circumferential surface of the fin joint 14 and cooling from the inside radiates and diffuses the heat from the primary piping 13 and drops the temperature of the main cock 16. Therefore, since the conductive heat becomes lower in the tab 17 and the connecting hole 18 of the main cock 16, the rubber hose 2 and the tab 17 also are low in temperature and free from heat deterioration.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a gas appliance device configured by connecting a gas appliance and a gas supply main pipe.

Structure of the conventional example and its problems In the conventional gas appliance apparatus of this type, for example, as shown in FIG. A joint 4 is connected to the rear end so that the upper part of the joint 4 faces above the gas open mounting part 5, and a base plate is connected to the upper part of the joint 4. A knob 7 is attached to the base cock, and a base cock connection port 8 is provided at the end, and the gas supply port 9 of the general gas table 2 and the base cock connection port 8 are connected to the rubber hose 1.
0 and is detachably connected.

However, the secondary pipe 3 is heated by the radiant heat from the inside of the gas open 1, and the joint 4, main cock, knob 7, and main cock connection port 8 connected to the secondary pipe 3 become hot due to heat conduction. In particular, there was a problem that the rubber hose 1o deteriorated due to heat and gas leaked from the original cock connection port 8.

OBJECTS OF THE INVENTION The present invention takes into consideration the above-mentioned conventional drawbacks and aims to prevent deterioration of the rubber hose or gas cock by reducing heat conduction to the rubber hose.

Structure of the Invention In order to achieve the above object, the gas appliance device of the present invention has a structure in which a cooling fin is provided between the main gas supply pipe and the rubber hose, and the heat of the rubber hose or the main cock is thereby dissipated. This has the effect that deterioration is prevented and gas leakage does not occur.

DESCRIPTION OF EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings.

In FIGS. 1 to 3, a gas staple 12 is placed above the gas oven 11. A fin sealing joint 14 is removably connected to the upper rear end of the primary piping 13 of the gas open 11, and the fin joint 14 faces above the open placement part 15 and is connected to the original cock 16. ing. The main cock 16 has a knob 17 for opening and closing the gas flow path, and the main cock connection port 18 is integrally formed at the end of the main cock 16. Reference numeral 19 denotes a gas supply port of the gas staple 12, which is connected to the original cock connection port 18 via a rubber hose 2o. 21 is a cap with a hole 2 larger than the fin sealing joint 14 in the center.
2 is made and fitted into the center of the fin sealing joint 14 and placed on the oven mounting part 15. Said cap 2
A piping port 23 larger in diameter than the fin sealing joint 14 is opened in the lower part of the fin sealing joint 14 at the position of the fin sealing joint 14, and the fin sealing joint 14 is raised upward. The fin sealing joint 14 is formed with a plurality of convex fins 24 and a concave groove 25, and a gas vent hole 26 is formed in the center thereof. Former cock 16. ! : A tapered screw 27 is formed to be detachably attached. Further, when the gas staple 12 is not set on the gas oven 11, the end of the secondary pipe 13 is sealed with a blind cap 28. Note that 29 in the figure indicates the inside of the open refrigerator.

The operation of the above configuration will be explained below.

The radiant heat from the gas oven 11 raises the temperature of the seam pipe 13 due to heat conduction, but the outer peripheral surface area of the plurality of fins 24 and grooves 25 at the fin sealing joint 14 is large and the wall thickness is thin. Therefore, the action of radiating heat works, and the temperature of the raw gas passing through the gas vent 26 cools both the groove part 25 and the fin part 24, and heat radiation from the outer circumferential surface of the fin sealing joint 14 and cooling from the inner surface work. However, as a synergistic effect, the amount of heat from the secondary pipe 13 is radiated and diffused, and the amount of heat transmitted to the source cock 16 is reduced. Therefore, as the temperature of the source cock 16 decreases, the conduction heat of the knob 17 and the source cock connection port 18 also decreases, so the rubber hose 2
0 and knob 17 also do not undergo thermal deterioration at low temperatures.

In this embodiment, the fin sealing joint 14 is detachable, but this is applicable both when the gas oven 11 is used alone as shown in FIG. 2, and when the gas oven 11 is used as shown in FIG.
In some cases, the gas staple 12 is placed and used. Generally, a dedicated gas oven 11 is manufactured for each oven, and the number of models increases, making inventory management and the like complicated. In this embodiment, when the gas staple 13 is placed on the gas oven 11, the fin sealing joint 14 is connected, and when the gas oven 11 is used alone, the fin sealing joint 14 is removed and the blind cap is closed. By installing 28, it is possible to accommodate two types of machine manufacturers, improving productivity and simplifying inventory management.

Furthermore, in this embodiment, the fin sealing joint 14 can be easily formed into a fin portion by simply machining several grooves in a hexagonal prism.

In the above embodiment, the secondary piping 13 passes through the gas open exterior and the primary piping 13 is heated in the open chamber interior 29, but the invention is not limited to this.
As shown in FIG. 4, the secondary pipe 13 may be exposed outdoors and heated by direct sunlight, or as shown in FIG. Even if the gas staple 12 is connected to the primary piping 13 heated by the heat of the gas oven 11 and the gas staple 12 via the fin sealing joint 14 near the source cock 16 with the rubber hose 2o. , the effects of the present invention can be achieved.

Effects of the Invention As is clear from the description of the embodiments above, according to the present invention, since fins are formed on the main pipe near the main cock or rubber hose, the conductive heat from the main pipe can be reduced, and the heat transfer to the main cock or rubber hose can be reduced. , it is possible to provide a safe gas appliance device that can prevent thermal deterioration and does not cause problems such as gas leakage.
