Description

[0001] DESCRIPTION [0002] Portable gas cooker gas cylinder insulation equipment [

The present invention relates to a portable gas-range gas-cylinder heat-insulating device, and more particularly, to a portable gas-range gas-case heat-insulating device which is provided with a gas- 0001] The present invention relates to a gas-

Generally, the portable gas range is convenient to carry and is used for cooking food, cooking meat or heating cooking utensils outdoors or indoors because of its high convenience.

When the operation of the portable gas range is normal, the internal temperature of the gas cylinder is lowered by the vaporization phenomenon. As a result, the risk of explosion due to temperature rise is extremely low. However, when heating is performed in the gas range, radiant heat generated from the cooking utensil or the like is transmitted to the gas cylinder, thereby increasing the internal pressure of the gas cylinder.

The normal pressure of the gas cylinder used in a conventional portable gas range is in the range of 2 to 3 kg / cm 2. The deformation pressure at which the gas cylinder can be deformed by the pressure increase is 13 kg / cm 2, and the internal pressure is 15 kg / The gas can explode.

According to the regulations of the Korea Gas Safety Corporation, it is obligatory to install a safety device so that the gas cylinder can be separated during use when the internal pressure of the gas cylinder is in the range of 5 ~ 7㎏ / ㎠. For example, in the case of Japan, it is specified in the range of 4 to 6 kg / cm 2.

The safeguards adopted in the Republic of Korea are mainly container detachable type, and in Japan, mainly used for the blocking of the flow.

The container detachable type means a method in which, when the internal pressure of the gas cylinder reaches a dangerous pressure, the gas container is disconnected from the governor inlet of the portable gas range to shut off the gas supply.

The flow-through type is a method of extinguishing the flame of the gas range by shutting off the gas supply prematurely when the pressure in the gas cylinder reaches a certain pressure range.

However, even if the gas supply is primarily stopped, the gas pressure is still inside the gas range, so that the internal pressure of the gas passage is raised by the radiant heat. It has a high possibility of being able to do.

Prior art related to the above-described container blocking safety device includes Korean Registered Utility Model No. 20-0240713, Korean Patent Publication No. 10-2003-0082234, Korean Patent Application No. 10-2000-0027086, Korean Patent Publication No. 2000- 0033398 and Japanese Patent No. 10-1511636 (hereinafter referred to as Patent Document 1)

Prior art relating to a safety device of a flow blocking type is disclosed in Korean Patent Registration No. 10-0399766 and Publication No. 2003-0090920.

On the other hand, as disclosed in Korean Utility Model No. 20-2009-0003999 (hereinafter referred to as "Patent Document 2"), there has been proposed a technique of covering a lid which is opened and closed so that the gas can be removed.

Hereinafter, preferred embodiments of the present invention will be described in more detail with reference to the accompanying drawings. The present invention is not limited to the embodiments.

FIG. 1 is a perspective view showing a state in which a lid of a portable gas range is opened to explain the present invention, and FIG. 2 is a partially enlarged cross-sectional view of the lid according to FIG.

As shown in the figure, the gas canister 200 is housed in the portable gas range 100 when cooking various kinds of foods, cooking meat, heating the cooking utensil, etc., Disclosed is an adiabatic device (1) which is provided to block heat conduction and radiant heat in a process of being cooked in a lid (110).

The portable gas range 100 has a known structure and includes a housing 102 and a burner 104 on one side of the housing 102 and a pedestal 105 on an upper side thereof and a gas cylinder 200 A pressing member 108 including a housing space 106 accommodated therein and a lever 107 for pressing the lid 110 and the gas cylinder 200 and a handle 109 for adjusting the flame.

Herein, an example in which the lid 110 is formed in an arc shape will be described as an example.

The present invention is intended to ensure safety from the risk of explosion by blocking heat conduction and radiant heat in the process of being heated for cooking on a lid which is covered after the gas cylinder is housed.

The heat insulating device 1 according to the present invention has a heat insulating material 12 such as a known glass wool having a size corresponding to the inner surface of the lid 110, A heat insulating pad 10 of different materials provided on an outer surface thereof with a heat insulating pocket 14 such as an ordinary aluminum sheet; And fixing portions 20 at both ends of the lid 110 so that one end and the other end of the heat-insulating pad 10 are coupled and fixed. The heat insulating material 12 may include a known polyurethane foam, an aqueous soft foam, a urea foam, a PUR, a PIR, a mineral wool, a heat reflecting and heat insulating material in addition to the glaze wool, Also,

The heat insulating pad 10 coupled to the lid 110 is also covered with the gas cylinder 200 at about 3/4 of the length of the gas cylinder 200, Can be increased. That is, since the upper and the lower surfaces of the gas cylinder are enclosed uniformly while the gas cylinder is housed, the heat insulating efficiency is high.

The joint fixing part 20 is press-fitted to each end of the lid 110 by bending one end and the other end of the heat-insulating pad 10 when the lid 110 is manufactured. At this time, since each end of the lid is bent to the cover of the portable gas range of the ready-made product, one end and the other end of the heat-insulating pad may be compressed and fixed by unfolding the bending portion.

In addition, the engaging and fixing portion may be engaged and fixed by a known bracket, bolt, screw, or the like in addition to banding.

The heat insulating pad may be fixed to the inner surface of the lid by using a well-known adhesive which is strongly resistant to heat.

According to the present invention, the heat transfer pad and the heat insulating pad, which cover the entire upper surface of the gas cylinder and the entire side surface of the gas cylinder, are prevented from being transferred directly to the gas cylinder during the cooking process, Thereby preventing the possibility that the gas can explode by overheating.

In addition, since the insulation pad is made of a different material, that is, a heat-insulating pocket that surrounds the heat-insulating material so that the heat-insulating efficiency is enhanced while the heat-insulating efficiency is enhanced, the transfer of heat and radiant heat is blocked to the utmost, .

In addition, the technical structure for fixing the insulating pad to the cover is not limited to complicated or troublesome work but is accomplished by compression bonding by a conventional banding, so that the installation work can be conveniently installed in a short time without troublesomeness.

Thus, in the process of using the portable gas range, the heat conduction and the radiant heat from the burner and the heating container are prevented from being transmitted to the gas cylinder by the heat insulating pad provided on the lid, so that the risk of explosion due to the heating of the gas cylinder is prevented, It has the condition that it can be.

The joint fixing part 20 includes at least one fixing ring 22 provided at a corresponding position of one end and the other end of the heat insulating pad 10 of the lid 110.

The fixing ring 22 formed on the cover 110 is formed through a cutting process and a bending process when the cover 110 is manufactured.

Accordingly, by inserting the heat insulating pads into the respective fixing rings formed by covering the heat insulating pads, that is, pushing one end and the other end of the heat insulating pads, the heat insulating pads can be more easily fixed without inconvenience or inconvenience. At this time, after one end and the other end of the heat insulating pad are inserted into the respective fixing rings, the fixing rings may be pressed and fixed by pressing.

This makes it possible to more easily and conveniently fix the heat-insulating pad provided on the inner surface of the lid. This provides convenience in that anyone can fix the heat-insulating pad easily and conveniently even in the state of having a separate heat-insulating pad.

As shown in the drawings, when the cover is covered with the heat insulating pad provided on the cover, the gas cylinder is positioned at the correct position and can be supported without fluidity when covering the gas cylinder.

The heat insulating pad 10 further includes a concave and convex portion 30 contacting the outer surface of the gas cylinder 200 to support the gas cylinder 200 to be positioned at a predetermined position.

The concave and convex portions 30 may be separately manufactured by a known method and attached or bonded to the heat insulating pad. Preferably, the concave-convex portion is integrally formed when the heat insulating material to be placed in the heat insulating pocket of the heat insulating pad is manufactured.

Accordingly, when the lid equipped with the heat insulating pad is covered, the gas cylinder in the accommodation space is supported so that the gas cylinder can be positioned in the correct position as the uneven portion is supported, and also the movement is prevented.

Thereby having the advantage that the gas can be stored and used more safely in use.

5 is a partially enlarged cross-sectional view for explaining another embodiment of the present invention.

As shown in the figure, in the above-described construction, since the used gas tank is pierced and discarded due to the characteristics of the portable gas range, it has been conventionally perforated by using other tools. However, the present invention is not limited to the portable gas range, Make it possible to perforate.

The housing 102 of the portable gas range 100 is provided so as not to protrude from the upper surface of the housing 102 and to protrude only when the gas cylinder 200 is punctured A perforated member 40 is provided.

The perforation member 40 includes a receiving space 42 provided in one side of the housing 102 and a long hole 44 formed in the receiving space 42 on a vertical line formed on one side of the housing 102 A lifting body 45 for lifting the lifting body 45 by fixing the perforating pin 45b to the upper surface of the lifting body 45a and the upper surface perforation pin 45b of the housing 102, And a stopper groove 44a through which the gripping protrusion 45a is hooked so that the lifting body 45 can be lifted up and down on the slot 44. [ The long hole and the stopper groove are formed in the shape of a " a "

When the gas in the gas cylinder is exhausted, the lifting body, which is the perforated member, is lifted up to the upper portion by using the grip protrusion protruded from the slot, and then the grip protrusion is rotated by the stopper groove, .

As a result, the perforated fin is protruded and supported by the through hole formed in the upper surface of the housing, thereby puncturing the gas-exhausted fuel tank. After the punching of the gas cylinder is completed, the grip protrusion held in the interstopper groove is rotated back to the long hole side to lower the lifting body, so that the punch pin protruding from the through hole does not protrude from the surface of the housing.

Thus, the perforating pin can be normally used without being protruded from the surface of the housing, and can be used by protruding to the surface of the housing only at the time of use, thereby improving the convenience of use, .
