First, the gas frying device according to the invention is provided with the heating member 10. The heating member 10 generates the combustion heat by heating and supplies the combustion heat to the gas frying device of the invention.
Also, the gas frying device of the invention is provided with a tank (an oil tank) 12.
As shown in FIGS. 1 and 2, a top surface of the tank 12 is opened, and a member to be heated, such as, cooking oil to be heated or the like, may be contained in the tank 12.
The front case 20 is disposed at the front surface of the tank 12. The front case 20 has a plate shape. The first through hole 22 is formed at the front case 20 so that the combustion heat can pass through the first through hole 22.
Further, the first distributor 30 is disposed from the rear surface of the front case 20 to an inside of the oil tank 12. The first distributor 30 controls a movement direction of the combustion heat and makes the combustion heat remained at an inside of the distributor heat the member to be heated.
The first distributor 30 may be formed of the case having the flow path therein for the above. The first distributor 30 has the second through hole 32 communicating with the first through hole 22, and the first hole 34 and the second hole 36 at both sides of the second through hole 32.
As shown in FIG. 3, each of the first hole 34 and the second hole 36 may have an extended shape extended to have a length greater than a width. The first hole 34 and the second hole 36 are inclined so that a distance between the first hole 34 and the second hole 36 decreases as they go downward.
The tank 12 is provided with the rear case 40. The rear case 40 may be disposed to correspond to the front case 20 and may be formed of the case having the flow path therein.
Particularly, as shown in FIG. 2, the rear case 40 has the outlet 42 to discharge a combustion exhaust gas at an upper side of the rear case 40. The third hole 44 and the fourth hole 46 are Attorney Ref: 1328P00ICA0 formed in pairs at a lower side of the rear case 40 so that the combustion exhaust gas, which transferred the combustion heat to the member to be heated in the oil tank 12 through the first, second, and third pipes, flows into the rear case 40.
The third hole 44 corresponds to a part of a lower portion of the first hole 34, and the fourth hole 46 corresponds to a part of a lower portion of the second hole 36.
That is, the combustion gas, which flowed into the rear case 40 through the third hole 44 and the fourth hole 46, passes through the flow path in the rear case 40, and then, is discharged to an outside through the outlet 42.
The second distributor 50 is provided at the front surface of the rear case 40. The second distributor 50 may be formed of the case having the flow path therein.
The second distributor 50 may have the third through hole 52 corresponding to the second through hole 32 of the first distributor 30.
Also, the second distributor 50 may have the fourth through hole 54 corresponding to the first hole 34 of the first distributor 30 and the fifth through hole 56 corresponding to the second hole 36 of the first distributor 30.
As shown in FIG. 2, the second distributor 50 is provided with an inclined plate 58.
The inclined plate 58 may be formed of inclined surfaces inclined from a center of the inclined plate 58 to both sides of the inclined plate 58 so that the center of the inclined plate 58 is protruded than the both sides of the inclined plate 58. The inclined plate 58 may be attached to the rear surface of the third through hole 52. That is, the inclined plate 58 guides or transfers the combustion heat, which flowed along the third through hole 52, to the second upper flow path 72 and the third upper flow path 82.
Heating pipes for heating the member to be heated is provided between the first distributor 30 and the second distributor 50. The pipes include the first pipe 60, the second pipe 70, and the third pipe 80. The first pipe 60 has the flow path therein, and communicates the second through hole 32 and the third through hole 52 to each other and guides the combustion heat generated by the burner.
The second pipe 70 is disposed at one side of the first pipe 60. The second pipe 70 is parallel to the first pipe 60 and has the flow path therein. The flow path of the second pipe 70 may be divided or partition into the second upper flow path 72 and the second lower flow =
path 74. The second upper flow path 72 communicates the first hole 34 and the fourth through hole 54, and the second lower flow path 74 communicates the first hole 34 and the third hole 44.
Attorney Ref: 1328P00ICA01 The third pipe 80 is disposed at the other side of the first pipe 60. Similar to the second pipe 70, the third pipe 80 is parallel to the first pipe 60 and has the flow path therein.
The flow path of the third pipe 80 may be divided or partition into the third upper flow path 82 and the third lower flow path 84. The third upper flow path 82 communicates the second hole 36 and the fifth through hole 56, and the third lower flow path 84 communicates the second hole 36 and the fourth hole 46.
Meanwhile, each of the second pipe 70 and the third pipe 80 has the flow path divided into the lower flow path and the upper flow path. In this instance, the gas frying device has a structure that the combustion heat having a temperature, which is higher than a temperature of the combustion heat passing through the lower flow path, passes through the upper flow path. This is for effectively prohibiting contamination of the cooking oil, which may induced by an oxidation of a foreign material that may be generated from the member to be cooked while frying.
The pipe having the upper flow path and the lower flow path may be manufactured by any of various methods. For example, the pipe having the upper flow path and the lower flow path may be formed by the following method.
Each of the second pipe 70 and the third pipe 80 may be formed by bending both ends of a plate of a metal material so that the both ends are in contact with each other and are in contact with a surface of the plate of the metal material to divide the upper flow path and the lower flow path. Since each of the upper flow path and the lower flow path is only for transferring the exhaust gas, the pipe having the upper flow path and the lower flow path can be manufactured by a simple process according to the above.
The second pipe 70 and the third pipe 80 are inclined so that a distance between the second lower flow path 74 and the third lower flow path 84 is smaller than a distance between the second upper flow path 72 and the third upper flow path 82. Then, when the combustion heat having a temperature, which is higher than a temperature of the combustion heat passing through the lower flow path, passes through the upper flow path, efficiency of heating the fried member can be maximized.
Also, the second pipe 70 and the third pipe 80 having extended shapes are disposed to be inclined, and thus, a foreign material which may be generated from the member to be cooked while frying can be easily guided to the bottom by its own weight.
Hereinafter, an operation of the gas frying device according to the invention will be described in detail.
Attorney Ref: 1328P001CA0 I
First, the heating member 10 is driven. When the heating member 10 is driven, combustion heat is generated, and the combustion heat is transferred to the first through hole 22 of the gas frying device according to the invention. The combustion gas heat that passed through the first through hole 22 passes through the second through hole 32, and then, is guided to the flow path in the first pipe 60. That is, the combustion gas of the highest temperature flows into the inside of the tank through the first pipe 60, and thus, a heat exchange with the member to be heated in the frying tank occurs.
Then, the combustion gas heat moves along the inner flow path of the first pipe 60 and is guided to the third hole 52 of the second distributor 50. The combustion gas heat that passed through the third through hole 52 is distributed by the inclined plate 58 and is guided to the second upper flow path 72 and the third upper flow path 82. While the combustion gas heat moves along the second upper flow path 72 and the third upper flow path 82, a heat exchange between the combustion gas having a relatively high temperature and the members to be heated, such as, the cooking oil and a material to be fried occurs, thereby increasing heat exchange efficiency.
The combustion gas heat, which moved along the second upper flow path 72 and the third upper flow path 82, is guided to the first hole 34 and the second hole 36 of the first distributor 30. Then, the combustion gas in the first hole 34 and the second hole 36 is distributed and is guided to the second lower flow path 74 and the third lower flow path 84.
That is, the combustion gas having a temperature lower than a temperature of the combustion gas passing through the upper flow paths 72 and 82 passes through the lower flow paths 74 and 84. This is for preventing the food from being stuck on a wall surface of the tank 12, which may be induced while frying by a drop of the food its own weight, by decreasing a temperature of a lower portion of the tank 12.
If the cooking oil is contaminated to a certain degree by the foreign material of the member to be cooked, the cooking oil should be replaced. According to the invention, a replacement cycle of the cooking oil can be lengthened.
The combustion gas guided to the lower flow paths 74 and 84 is stayed for a long time in the frying tank while passing through lower end portions of the second and third pipes 70 and 80, thereby sufficiently performing a heat exchange with the member to be heated. And then, the combustion heat passed through the third hole 44 and the fourth hole 46 rises upward along the inner flow path of the rear case 40 and is discharged to the outside through the outlet 42.
Attorney Ref: 1328P00ICA01 As a result of a test conducted by a public agency using the gas frying device having the above-described structure, time to reach a temperature of 200 C is 11.8 minutes, which is remarkably effective, compared with 30 minutes of KSB8131 standard.

Attorney Ref: 1328P001CA0 I
First, the heating member 10 is driven. When the heating member 10 is driven, combustion heat is generated, and the combustion heat is transferred to the first through hole 22 of the gas frying device according to the invention. The combustion gas heat that passed through the first through hole 22 passes through the second through hole 32, and then, is guided to the flow path in the first pipe 60. That is, the combustion gas of the highest temperature flows into the inside of the tank through the first pipe 60, and thus, a heat exchange with the member to be heated in the frying tank occurs.
Then, the combustion gas heat moves along the inner flow path of the first pipe 60 and is guided to the third hole 52 of the second distributor 50. The combustion gas heat that passed through the third through hole 52 is distributed by the inclined plate 58 and is guided to the second upper flow path 72 and the third upper flow path 82. While the combustion gas heat moves along the second upper flow path 72 and the third upper flow path 82, a heat exchange between the combustion gas having a relatively high temperature and the members to be heated, such as, the cooking oil and a material to be fried occurs, thereby increasing heat exchange efficiency.
The combustion gas heat, which moved along the second upper flow path 72 and the third upper flow path 82, is guided to the first hole 34 and the second hole 36 of the first distributor 30. Then, the combustion gas in the first hole 34 and the second hole 36 is distributed and is guided to the second lower flow path 74 and the third lower flow path 84.
That is, the combustion gas having a temperature lower than a temperature of the combustion gas passing through the upper flow paths 72 and 82 passes through the lower flow paths 74 and 84. This is for preventing the food from being stuck on a wall surface of the tank 12, which may be induced while frying by a drop of the food its own weight, by decreasing a temperature of a lower portion of the tank 12.
If the cooking oil is contaminated to a certain degree by the foreign material of the member to be cooked, the cooking oil should be replaced. According to the invention, a replacement cycle of the cooking oil can be lengthened.
The combustion gas guided to the lower flow paths 74 and 84 is stayed for a long time in the frying tank while passing through lower end portions of the second and third pipes 70 and 80, thereby sufficiently performing a heat exchange with the member to be heated. And then, the combustion heat passed through the third hole 44 and the fourth hole 46 rises upward along the inner flow path of the rear case 40 and is discharged to the outside through the outlet 42.
Attorney Ref: 1328P00ICA01 As a result of a test conducted by a public agency using the gas frying device having the above-described structure, time to reach a temperature of 200 C is 11.8 minutes, which is remarkably effective, compared with 30 minutes of KSB8131 standard.
Thus, it can be seen that the gas frying device according to the embodiment is more efficient than the conventional gas frying device.
