Description

DETAILED DESCRIPTION OF THE INVENTION FIELD OF INDUSTRIAL APPLICATION The present invention relates to an electric seven-tier fryer for deep-frying foods.

BACKGROUND OF THE INVENTION Recently, cooking devices that utilize far-infrared radiation for heating pots, frying pans, and even hot plates have been proposed and are being widely applied.

This tendency can also be seen in fryers; for example, as seen in Japanese Patent Application Laid-Open No. 60-45329, there is a long-length fryer in which ceramics that emit long-wavelength infrared rays are welded to the inside of the bottom of the oil tank, and an electric heater is embedded in the outer surface. There have been proposed fryers using wavelength infrared rays and fryers in which the entire inner surface of an oil tank is coated with a far-infrared radiating material, as seen in Japanese Utility Model Publication No. 59-33287 and Japanese Utility Model Application Publication No. 69-71718.

Problems to be Solved by the Invention However, in the case where only the bottom surface of the oil tank is treated with far infrared rays, the amount of far infrared rays emitted is small and the effect is not very good. Furthermore, in the case where the entire inner surface of the oil tank is treated with far-infrared rays, there is a problem in that when used for a long period of time, a phenomenon in which oil sticks to the areas where no oil is present is observed.

The present invention solves the above-mentioned problems, and aims to provide a fryer that can further improve the efficiency of far-infrared radiation and is free from oil stickiness.

Means for Solving the Problems In order to solve the above problems, the present invention coats the inner surface of the oil tank with a far-infrared radiating material,
The other parts are coated with fluororesin.

General Function: When heating a substance, it is important that the radiation characteristics of the object to be heated match the infrared absorption characteristics of the object to be heated.

For these reasons, heating using far-infrared radiation is said to be effective.

In addition, in order to increase the heating effect by this far-infrared radiation,
It is sufficient to increase the amount of far-infrared rays radiated to suit the object to be heated. For this purpose, it is necessary to either (1) increase the operating temperature or (2) increase the radiation area.

The present invention particularly focuses on (2) to increase the radiation area, and the part of the inner surface of the oil tank into which oil is to be filled is coated with a far-infrared radiation material.

On the other hand, these materials generally have poor non-stick properties, and when used for a long time, oil tends to stick to them, causing problems in actual use. The non-stick areas, that is, the areas that do not require far-infrared radiation, are coated with a non-adhesive fluororesin to prevent oil from sticking.

For the above reasons, according to the present invention, it is possible to further improve the efficiency of far-infrared radiation and to obtain a fryer that does not get oily even after long-term use.

Embodiment Hereinafter, one embodiment of the present invention will be described based on the accompanying drawings. In FIGS. 1 and 2, 1 is a fryer main body, and this fryer main body 1 controls the temperature of an oil tank 2 made of cast aluminum and a sheathed heater press-welded to the bottom back side of the oil tank 2. It has a temperature control knob 3 for use with the device, and an appliance plug 4 that can be connected to the main body 1 using magnetic force.

Further, the inner surface of the oil tank 2 is coated with a far-infrared ray emitting material 2a on the inner surface thereof, and the inner surface of the oil tank 2 is coated with a fluororesin 2b.

When a fryer having such a configuration is heated by a sheathed heater pressed against the back side of the bottom surface of the oil tank 2, far infrared rays are emitted from the far infrared ray radiating material 2a coated on the part into which the oil is placed.

Therefore, when tempura is fried with oil in the 7-layer, the food can be efficiently fried due to the surface heating of the food through heat conduction by the oil, as well as the effect of radiant heating from the far infrared rays generated.

In addition, the action of far infrared rays makes it possible to cook delicious fried foods. Also, sticking due to oil splashed during cooking can be prevented because the entire area that is not covered with oil is coated with fluororesin.

In the above examples, the material of the far infrared ray emitting material was not particularly mentioned, but in the fryer, T10°, At
Materials such as 2o3, 5i02 and Z r O2 are suitable.

Effects of the Invention As is clear from the above description, according to the present invention, the part of the inner surface of the oil tank into which oil is to be filled is coated with a far-infrared radiation material, and the other parts are coated with a fluororesin. This makes it possible to further improve the efficiency of far-infrared radiation and provide a fryer that does not get oily.
