Description

[Detailed Description of the Invention] The present invention relates to an electric fryer heater that does not deteriorate oil quality.

In recent years, gas-type fryer heaters have been avoided due to safety issues, and demand for electric-type heaters has been increasing.

A conventional electric fryer heater will be explained based on the drawings. In Fig. 1, 1 is an outer frame, 2 is an oil pan, and 3 is a conventional fryer heater in which a sheathed heater is bent in a meandering manner near the bottom of the oil pan 2. It is located at the top. 4 is oil stored in oil pan 2.

In the above-described configuration, the fryer heater 3
Since the sheathed heater is always used in the same oil as the food being cooked, it requires corrosion resistance and also has hygiene issues. After molding, surface treatments such as electrolytic polishing and passivation treatment using neutralization treatment are required, resulting in the heater itself being expensive. In particular, in the case of commercial fryers, it is necessary to raise the oil temperature in a short time, and due to heat capacity, fryers with high power consumption of about 6 to 10 KW are used. As a result, the pipe surface load (W/cm ² ) of the sheathed heater becomes high, and the heater surface temperature becomes considerably high compared to the appropriate oil temperature (approximately 180°C), which has the disadvantage that the oil near the heater easily deteriorates. Ta.

The present invention was made in order to solve the above-mentioned conventional problems, and by casting multiple sheathed heaters into the heater body and preventing direct contact between the oil and the sheathed heaters, it is possible to reduce the cost and deteriorate the oil. The object of the present invention is to provide a heater for a fryer with a small amount of heat.

Embodiments of the present invention will be described below with reference to the drawings. In FIG. 2, 11 is an outer frame, 12 is an oil pan, and 13 is a fryer heater, which are installed horizontally near the bottom of the oil pan 12. 14 is oil stored in the oil pan 12.

As shown in FIG. 3, the fryer heater 13 has a cylindrical heater body 15 made of an alloy such as aluminum, and an aluminum pipe 16 provided in the center. Reference numeral 17 denotes a sheathed heater bent in a U-shape, which is located on the outer periphery of the pipe 16, and a plurality of sheathed heaters 1 are attached to the heater body 15.
7 is injected. Reference numeral 15a denotes a cut groove located below the heater body 15 and extending from the surface of the heater body 15 to the space of the pipe 16 in the length direction of the space of the pipe 16. When it is attached to the pan 12, it is attached so that the cut groove 15a is located at the bottom. 15
b, 15c are located above the heater main body 15,
This is a through hole provided so as to extend from the surface of the heater body 15 to the space of the pipe 16. 18 is a flange provided at the base of the heater body 15, 19 is a mounting screw portion, and 20 is a heater terminal.

In the above-described configuration, when the oil pan 12 is filled with oil and the sheathed heater 17 is energized through the heater terminal 20, the oil 14 is heated via the heater body 15. Although the surface of the sheathed heater 17 is at a high temperature, the surface of the fryer heater 13, which has a large surface area, does not reach a high temperature so much that oil deterioration can be prevented. According to experiments, when the oil temperature is set to 180°C, the surface temperature of the conventional fryer heater is 230 to 240°C, whereas the surface temperature of the fryer heater 13 of this embodiment is 185°C. The temperature difference between the heater and oil has been reduced to less than 1/10 compared to conventional models. Furthermore, since the sheathed heater 17 does not come into contact with the oil 14, there is no need to use expensive materials and it can be constructed of inexpensive iron.

In addition, the cut groove 15a and the through holes 15b, 15
c, the oil easily enters the inside of the heater body 15 and causes convection, and the cut grooves 15a prevent oil 14 residue and the like from accumulating inside the heater body 15.

As is clear from the above explanation, according to the present invention, multiple sheathed heaters are cast into the heater body to prevent direct contact between the oil and the sheathed heaters. It is possible to provide a fryer heater that causes little deterioration of oil quality.

The heater body is formed into a cylindrical shape with a space in the center, and a cut groove is provided below the heater body and extends from the heater surface to the space in the length direction of the space, and a groove is provided above the heater body. Since a plurality of through holes are provided extending from the surface of the heater body to the space, oil can easily enter the inside of the heater body and cause convection.
The presence of the grooves also reliably prevents oil scum and the like from accumulating inside the heater body.
