Description

[Detailed Description of the Invention] [Field of Use and Outline of the Invention] The present invention relates to a fryer, and more particularly to a commercial fryer in which an oil tank housed in a casing is heated from below by a burner. The surface of the casing is prevented from being overheated by the combustion exhaust gas generated inside the casing.

[Prior Art and Problems Therefor] In a conventional commercial fryer, as shown in FIG. 3, an oil tank (2) housed in a casing (1) has a burner (3).
The air in the casing (1) is heated and rises during use, and is exhausted from the exhaust stack (11) to the outside of the casing (1).

Since the combustion exhaust gas has a relatively high temperature, the combustion exhaust gas directly heats the casing (1) and the surface temperature of the casing (1) becomes high, which may cause burns or the like, which is dangerous.

[Technical Problem] According to the present invention, such an "oil tank (2), a burner (3) for heating the oil tank (2), and a casing (1) accommodating the oil tank (2) and the burner (3) are provided. ) And a combustion chamber (20) formed below the bottom surface of the oil tank (2) via an exhaust chamber (23) formed in the body of the oil tank (2),
In order to prevent the risk that the casing (1) is overheated by combustion exhaust and its surface temperature rises in the fryer which is communicated with the exhaust pipe (11) formed at the rear of the casing (1), The technical problem is that (1) is not directly affected by the combustion exhaust gas.

[Technical Means] The technical means of the present invention taken to solve the above technical problem is "the first compartment in which the four sides of the combustion chamber (20) and the exhaust chamber (23) are opened only to the exhaust stack (11). The first partition wall (21) and the second partition wall (41) are surrounded by the second partition wall (41) while being surrounded by the wall (21) and only the front and both side surfaces of the first partition wall (21). A ventilation chamber (40) is configured with the partition wall (41), and both upper and lower ends of the ventilation chamber (40) communicate with the outside, and between the second partition wall (41) and the outer wall of the casing (1). A vacant chamber (10) is provided in the chamber, and the upper part of the vacant chamber (10) communicates with the ventilation chamber (40).
0) has electrical components built in. ”

[Operation] The technical means of the present invention operates as follows.

By igniting the burner (3), the air in the combustion chamber (20) becomes combustion exhaust gas, rises in the exhaust chamber (23), and enters the exhaust stack (11) continuous with the exhaust chamber (23). It flows in and is exhausted to the outside of the casing (1).

This combustion exhaust heats the first partition wall (21) and also warms the air in the adjacent flow chamber (40). The warmed air rises and is discharged from the upper end of the ventilation chamber (40) to the outside, and the outside air is sent into the ventilation chamber (40) through the ventilation hole at the bottom of the casing (1). Becomes That is, air convection occurs in the ventilation chamber (40). In this way, the temperature in the ventilation chamber (40) in which air is constantly exchanged does not rise, and the temperature rise in the second partition wall (41) is suppressed to a low level.

Since the vacant chamber (10) is further provided between the second partition wall (41) and the casing (1), the outer surface of the casing (1) is for the combustion exhaust gas in the combustion chamber (20). Not affected.

The air in the empty chamber (10) provided between the outer wall of the casing (1) and the ventilation chamber (40) is located above the empty chamber (10).
Is in communication with. In addition, in this kind of equipment,
Since there are some air gaps such as gaps and openings in the lower part of (0), the draft action in the aeration chamber (40) sucks fresh air from the air suction part, and the fresh air is absorbed in the aeration chamber (40). ) Is discharged to the outside through the communication part with the upper part. Therefore, an air-cooling action is generated also in the empty chamber (10).

[Effects] The present invention having the above-described configuration has the following unique effects.

Since the surface of the casing (1) is not affected by combustion exhaust gas, its surface temperature does not rise and it is safe to touch the casing (1) while using the fryer.

Further, in order to form the vacant chamber (10) between the casing (1) and the second partition wall (41), only the outside of the front surface and both side surfaces of the first partition wall (21) is the second partition wall ( Since it is surrounded by 41), the installation area of the second partition wall (41) for performing the heat insulating effect by the empty room (10) can be minimized, and the entire instrument can be miniaturized. At the same time, the internal structure can be simplified.

Furthermore, since an air cooling effect is generated also in this empty chamber (10), the effect of preventing overheating of the electrical components arranged in this empty chamber (10) is ensured. Further, since the air-cooling opening or the like is not formed in the front surface of the casing (1), the electric components and the like provided in the front-side casing (10) of the casing are contaminated or contaminated by splashed oil or the like. Don't worry.

[Embodiment] An embodiment of the present invention will be described below with reference to the drawings.

In the embodiment of the present invention, the oil tank (2) with the grips (26) (26) is dropped from the opening formed in the upper surface of the casing (1) to accommodate the oil tank and the oil splashes above the oil tank (2).
