## Abstract

A frying pan having a cooking oil supply device is disclosed, in which the cooking oil is supplied into the frying pan by means of a piston, the piston being slidably installed within a cylinder. The frying pan having a cooking oil supplying device includes: the main body 10 of the frying pan for cooking foods; a heat insulating member 16 coupled with a coupling portion 12 of a wall portion 10b of the main body 10, for blocking a thermal conduction from a bottom 10a of the main body 10; a cooking oil storing device 20 coupled to an end of the heat insulating member 16, for storing a cooking oil and for serving as a handle; and a coupling means 18 for coupling the heat insulating member 16 and the cooking oil storing device 20 together in an air-tight state.

## Claims

### Claim 1

A frying pan having a cooking oil supplying device, comprising:
a main body of the frying pan for cooking foods;
a wall portion defined by said main body, said wall portion having a coupling portion;
a heat insulating member coupled with said coupling portion, for blocking a thermal conduction from a bottom of said main body;
a cooking oil storing device coupled to an end of said heat insulating member, for storing a cooking oil and for serving as a handle; and
a coupling means for coupling said heat insulating member and said cooking oil storing device together in an air-tight state.

### Claim 2 (depends on 1)

The frying pan as claimed in claim 1, wherein said main body comprises:
said bottom;
said wall portion formed integrally with said bottom around it;
a plurality of oil supply passages formed on a side of said wall portion and communicating to said bottom; and
said coupling portion having a through hole for receiving the cooking oil from said cooking oil storing device through said heat insulating member.

### Claim 3 (depends on 1)

The frying pan as claimed in claim 1, wherein said heat insulating member is coupled to a coupling portion formed on said wall portion, and is made of a heat insulating material so as to serve as a thermal barrier for a heat from said heated main body of the frying pan during a cooking, and so as to prevent a degeneration of the cooking oil of said cooking oil storing device due to the heat.

### Claim 4 (depends on 1)

The frying pan as claimed in claim 1, wherein said heat insulating member comprises:
a coupling protuberance having external threads so as to be threadably coupled to the through hole of said coupling portion;
a flange integrally formed around the circumference thereof; and
an oil supply tube constituting a through passage in a lengthwise direction so as to supply the cooking oil to said bottom of said main body.

### Claim 5 (depends on 1)

The frying pan as claimed in claim 1, wherein said cooking oil storing device is made of a transparent material so as to make it possible to confirm the amount of the stored cooking oil by human eyes.

### Claim 6 (depends on 1)

The frying pan as claimed in claim 1, wherein said cooking oil storing device comprises:
a thread portion having a through hole for receiving said oil supply tube of said heat insulating member, and for being coupled with said heat insulating member in an air-tight state by means of said coupling means;
a hollow portion for storing the cooking oil;
a cooking oil injecting/discharging hole for discharging the stored cooking oil out of said hollow portion and for injecting the cooking oil into said hollow portion;
a cap for sealingly closing said cooking oil injecting/discharging hole; and
a cooking oil supplying means for supplying the cooking oil from said hollow portion through said oil supply tube and said oil supply passages of said wall portion to said bottom.

### Claim 7 (depends on 6)

The frying pan as claimed in claim 6, wherein said cooking oil supplying means is installed in said cooking oil storing device in such a manner that it absorbs the cooking oil from said hollow portion and supplies the absorbed cooking oil through an outlet to said oil supply tube of said heat insulating member.

### Claim 8 (depends on 6)

The frying pan as claimed in claim 6, wherein said cooking oil supplying means comprises:
a cylinder having a suction hole for sucking the cooking oil from said hollow portion of said cooking oil storing device, and having an outlet for supplying the sucked cooking oil to said oil supply tube of said heat insulating member;
a cooking oil sucking/discharging unit installed within said cylinder, for sucking the stored cooking oil from said hollow portion of said cooking oil storing device through said suction hole so as to supply it through said outlet to said oil supply tube;
an elastic member for forcing up said cooking oil sucking/discharging unit;
a steel ball installed between said elastic member and said suction hole of said cylinder in a vertically movable manner, so as to suck the stored cooking oil into said cylinder from said hollow portion of said cooking oil storing device during the upward movement of said cooking oil sucking/discharging unit, and so as to close said suction hole to prevent the introduction of the cooking oil into said cylinder during a downward movement of a piston;
a cooking oil discharging unit installed within said outlet, for supplying the cooking oil through said oil supply tube to said bottom of said main body of the frying pan during a downward movement of said cooking oil sucking/discharging unit; and
a cap for covering the upper opening of said cylinder, a supporting rod of said cooking oil sucking/discharging unit passing through it.
