FIG. 3 is a longitudinal sectional view of a cut-away side of a fryer according to an embodiment of the present invention, showing a main part of the exhaust induction and heat shielding apparatus.

Referring to FIG. 3, an exhaust unit including a front panel 120 is provided at one side of a main body of a fryer 100. The exhaust unit includes a front panel 120, The exhaust portion includes an exhaust duct 160 that faces a hood forming an exhaust gas exhaust passage in the fryer body and an exhaust port 190 for exhausting exhaust gas. And a heat shielding unit 130 installed along the rear surface of the front panel 120 to block thermal conduction of the exhaust gas radiant heat.

Referring to FIG. 3, the apparatus for inducing and heating the fryer according to another embodiment of the present invention comprises an exhaust unit provided on one side of the body of the fryer 100 and including the front panel 120. The exhaust portion includes an exhaust duct 160 that faces a hood forming an exhaust gas exhaust passage in the fryer body and an exhaust port 190 for exhausting exhaust gas. Further, a heat shielding unit 130 is provided along the back surface of the front panel 120 of the exhaust unit to block thermal conduction of the exhaust gas radiant heat. And means for activating the exhaust gas exhaust flow in the fryer body.

Here, the exhaust unit has a protruding structure that extends upward from one side of the fryer body for exhaust efficiency, and a front panel 120 is placed on a front portion of the fryer body.

Referring to FIG. 3, all of the apparatuses for venting and heating the fryer according to another embodiment of the present invention are related to a structure in which heat inside the fryer body is blocked from being transmitted to the front panel 120 constituting the ventilation unit, It is possible to increase the self exhaust speed of the exhaust duct 160 through the activation of the exhaust gas flow through the exhaust duct 160 including the heat shielding means 130 which is the first embodiment or the second embodiment, A structure for rapidly discharging the heat in the fryer instead of reducing the flow stagnation time of the exhaust gas, or a composite structure of the first and second embodiments, or any one of them.

The heat shielding means 130 is spaced apart from the front panel 120 and the exhaust duct 160 of the exhaust portion of the body of the fryer 100. And the lower portion has an upper flow gradient guiding plate for guiding exhaust of radiant heat in the fryer body. And a plate-shaped film body extending from the base plate and extending to correspond to the back surface of the front panel 120 of the exhaust unit. And the tip of the plate-shaped membrane body is fixed around the exhaust port 190 so as to induce radiant heat to the exhaust port 190.

The heat shielding unit 130 shields the radiation heat conducted in the fryer body from being conducted to the front panel 120 of the exhaust unit, which will be described with reference to FIG.

4 is a flow chart of an exhaust gas exhaust flow through a hood and an exhaust duct of a fryer according to an embodiment of the present invention.

4, the exhaust gas generated by the ignition and combustion of the heat source such as the burner G first flows in the direction of the arrow ①, which is the periphery of the tank 110, and flows in the direction of the arrow ② around the frying tank 110, (110) to heat the oil or raise the temperature. The exhaust gas continuously flowing in the direction of the arrow (2) is guided along the hood plate (170) and has an upward flow path toward the direction of arrow (3).

At this time, most of the exhaust gas is guided to the exhaust tube 160 and rises in the direction of arrow 4 to exit to the exhaust port 190 to complete the exhaust. However, in the process of introducing or guiding the exhaust gas to the hood plate 170 And transmits radiant heat a toward the front panel 120. Here, the radiant heat (a) includes combustion heat generated when the exhaust gas is exhausted or generated when the heat source in the fryer body is burned. Therefore, the radiation heat a transmitted to the front panel 120 of the exhaust unit may be the heat passing through the exhaust duct 160 and the heat of combustion in the body of the fryer.

Although the radiant heat a is exposed to the condition of continuing deterioration of the front panel 120 of the exhaust part during the exhaust gas exhaust, the heat shielding unit 130 functions to prevent the problem that the radiant heat a is directly applied to the front panel 120, .

Preferably, the heat shielding means 130 is made of a plate-shaped body and is fitted with a clearance on the back surface of the front panel 120. Further, it is advantageous to attach the front panel 120 of the exhaust unit with a clearance corresponding thereto. It is preferable to provide an inclined surface that narrows the angle toward the upper part so as to collect radiant heat in the fryer body toward the exhaust port 190. 3 and 4, an example is shown in which the flow space 180 in which the radiant heat a flows is formed by an inclined surface, and the upper portion is formed by an inclined flow path narrower than the lower portion. The radiant heat a is rapidly discharged through the exhaust port 190 It is advantageous.

In another embodiment of the present invention, the device for venting and heating the fryer may include means for activating the exhaust gas exhaust flow in the fryer body. In this case, the flow path shape of the ventilation duct 160 Can be configured through design.

The exhaust duct 160 is preferably formed to have an exhaust gas fluid flow space difference. For example, the upper portion 140 and the lower portion 150 may be divided into the upper portion 140 and the lower portion 150, and the inclination θ may be formed on the wall surface of the upper portion 140 so that the width L2 of the upper portion 140 is greater than the width L1 The width L2 of the exhaust duct 160 closer to the exhaust port 190 is smaller than the width L1 of the exhaust port 190 farther from the exhaust port 190. In this case, By forming the exhaust flow path, the exhaust duct 160 increases the exhaust speed as compared with the previous flat exhaust type exhaust duct, and quickly discharges the internal heat or exhaust gas.

The front end of the heat shielding means 130 and the front end of the exhaust duct 160 are arranged so as to face each other inside the exhaust port 190. When the opposed surfaces facing each other are formed as spaced spaces formed by spaced gaps, The exhaust gas discharged along the exhaust duct 160 and the heat of the inner part flow space 180 of the inlet front panel 120 are separated and discharged at the same time.

The apparatus for inducing and heating the fryer according to the embodiment of the present invention prevents radiant heat in the fryer body from being transmitted to the front panel of the exhaust part by interrupting the radiant heat inside the body of the fryer to prevent high temperature of the front panel of the exhaust part, Thereby promoting the discharge of the exhaust gas through the exhaust duct, thereby preventing the hot surface of the exhaust front panel due to heat stagnation or residue in the exhaust duct.

In the apparatus for inducing and heating the fryer according to the embodiment of the present invention, the temperature of the front panel of the fryer is lowered to prevent the cooking of the frying oil and the frying powder from being burnt on the front panel of the exhaust part, And provides a high-quality fryer, and prevents the problem of burns due to user's care due to the high temperature of the front panel of the fryer exhaust part by lowering the temperature of the exhaust front part.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is clearly understood that the same is by way of illustration and example only and is not to be taken by way of illustration, .
