Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an infrared cooking apparatus,

[0001] The present invention relates to an infrared cooker, and more particularly, to an infrared cooker that minimizes a temperature difference of a cooking fan disposed below the heating head through horizontal rotation of a heating head for irradiating a heat source from top to bottom, And the position of the heating head can be changed so that the operation of the heating element can be automatically stopped when necessary.

Well-Being has become a trend that leads our society as the number of people who recognize the illness of modern industrial society and harmonize their mental and physical health have increased the happiness and more beautiful life. In this way, it is natural for me and my family to think about the environment in which we live as much as we think about our family, in order to enjoy a healthy life of 'eating well and living well'.

Professor sidney mintz, an anthropologist at Johns Hopkins University, said, "Food is the greatest joy we can get, and eating for ourselves can never be purely biological. The food contains a history linked to the past with people who eat it. " In this way, it emphasizes that food not only meets human instinctive desires but also develops the culture of society.

However, there are positive aspects such as diversification of food culture and improvement of energy and nutrition level, which are divergent from the monotonous traditional dietary pattern due to the globalization of dietary life in Korea. However, due to the increase of consumption of high fat, Related health problems. In particular, it maintains a dietary culture that cooks meat, fish, and fish such as cattle, pigs, chickens, and ducks with grilling.

For example, when meat or fish are cooked at high temperature, a substance called HCAs (Heterocyclic amines) is produced, which is a carcinogenic concern corresponding to levels 2-3 of the criteria of the International Agency for Research on Cancer. HCAs are produced more in meat-rich meat than in soft tissues such as milk, eggs, tofu, and liver, and more often when cooked with barbecues, hot plates (cooking pan), etc., which are cooked directly by frying or heat, rather than heated oven roasts.

In order to reduce the amount of HCAs, it is advisable to discard the juice produced after warming for 2 minutes with a premix range before bake or frying, or to adjust the cooking temperature as low as possible to 150-160 ° C., Take measures such as avoiding roasted flame and cooking as far as possible from flame.

However, in reality, it is a fact that most restaurants and homes cook grilled or hot plates to cook food in the form of fire grill. Therefore, when cooking meat or fish as a fire grill, The problem is not solved.

In recognition of such a problem, an infrared cooker reinterpreted from the viewpoint of well-being has recently gained popularity, and the infrared cooker utilizes infrared rays as a heat source of a cooker, and infrared rays directly touch cooking material It is a great advantage that it is more efficient than other products and has a faster cooking speed because it is cooked by cooking method. Especially, it solves the problems of meat sticking, burning, smoke, smell and oil splashing when meat is baked, and has advantages such as thermal efficiency, safety, and non-toxic odor compared to existing heat sources.

Based on the above-mentioned technical idea, Korean Patent No. 10-0833966 discloses that an infrared lamp directly irradiates infrared rays onto a cooking rotary fan to burn the surface of a cooking material, or to heat the infrared heating A cooker has been disclosed.

FIG. 1 is an exploded perspective view showing a structure of a conventional infrared heating cooker. In the conventional infrared cooking cooker, as shown in FIG. 1, a shaft hole 911 is formed at the center of the upper surface, A pedestal 910 provided with a switch 915 for making a switch; Shaped container capable of holding a cooking material on the upper surface thereof. An axial protrusion 921 is detachably inserted into the shaft hole 911 at the center of the lower surface. Rotating fans 920 and 920 ', heated by receiving infrared rays, and; A support 930 installed at one side of the pedestal 910 in the vertical direction; And an infrared ray irradiating unit 940 installed at an upper end of the support base 930 and including an infrared lamp that receives power and emits infrared rays toward the rotary fans 920 and 920 '.

According to the related art, the infrared lamp directly irradiates the cooked material placed on the rotary fans 920 and 920 'to irradiate the upper and inner parts of the cooking material, and at the same time, The bidirectional heating method in which the fans 920 and 920 'directly cook the lower part of the cooking material has a high thermal efficiency and has an effect of uniformly cooking the whole without burning the cooking material.

However, due to the structural characteristic that the position of the hair removal part 940 can not be changed (changed), the infrared rays are intensively irradiated only on the cooking material placed in the central area of the rotary fans 920 and 920 ' 920, and 920 ', and the cooking material in the peripheral region is relatively less ripe.

In addition, due to the above-mentioned reasons, there is a limit in efficiently cooking and baking the cooking material, making the cooking process inconvenient and wasting more time than cooking the food, resulting in the texture of the cooked food It has been accompanied by a problem of dropping.

An assembly space for internally receiving and mounting the limit switch is provided inside the first assembly bundle so as not to interfere with rotational movement of the upper strut during horizontal rotation of the heating head,
Wherein a pushing piece for operating any one of the limit switches positioned on the inner wall surface of the assembly space at the rotation direction side of the heating head when the heating head rotates is protruded and formed at the tip of the first assembly bundle. This is a possible infrared cooker.
6. The method of claim 5,
The pivoting device includes a second assembly bundle incorporated in the inlet portion of the upper support bar,
A servomotor driven by an applied electric power in a state of being fixedly mounted on an inner side of an upper end portion of the lower strut,
A worm gear which rotates by being driven by the servomotor in a state of being linked to the second assembly bundle and the servomotor so that the upper support bar rotates itself by rotation and rotation of the second assembly bundle;
The upper strut can be rotated in a reverse direction when the upper strut reaches the limited rotation limit, or the power supply to the heating element is interrupted Wherein the second limit sensor comprises a first limit sensor and a second limit sensor.
8. The method of claim 7,
The second assembly bundle includes a through hole vertically penetrating the one side portion of the second assembly bundle for passing the electric wiring connected from the support body to the heating head through the inner space of the support,
A rotation shaft for assembling the worm wheel of the worm gear is protruded from a lower central portion,
Wherein a fixing clip for fixing the position of the electric wiring is further provided at a lower side portion of the through hole.
9. The method of claim 8,
The second limit sensor includes a plurality of second position sensors attached to the inner wall of the upper end of the lower support bar at predetermined intervals in consideration of the left and right turning radii of the upper support bar,
A second detection unit that detects the rotation of the worm wheel when the worm wheel is rotated with respect to one of the second position sensors when the worm wheel is rotated in a state of being attached to one side of the worm wheel circumferential surface between the second position sensors, And a sensor for detecting the position of the heating head.
