It can not touch and it more accurately measure than the temperature sensor or the ultraviolet-ray sensor. CONSTITUTION: A cooker of automatic temperature control comprises a heat source(30), a cooker(20), an infrared rays sensor(40), a controller(10). The heating source supplies the heat in order to take care of one's the food. The cooker takes care of one's the food to the heat provided from the heating source. The infrared rays sensor senses the temperature of cooker. According to the temperature which the controller is detected with the infrared rays sensor, the supply of the heating source is controlled. The heating source is the steam. In the lower inside of the cooker, the heat medium oil steam enters. It boils down and the whole is warm made. Cooker is warm made by using the heat medium oil. In that way the temperature difference of the center of cooker or outside can be reduced.

Description

Cooker capable of controlling the cooking temperature automatically and the controlling method for the same}

The present invention relates to a cooker capable of automatic temperature control and a control method thereof, and in particular, by detecting the temperature of the fire plate using the red-line sensor and automatically calculating the relationship between the detected temperature and the set temperature to control the heat source, eventually cooking The present invention relates to a cooker capable of automatically adjusting the temperature of the cooked food and controlling the same.

There are many kinds of cooking utensils. Usually, the heat source is classified according to what it is. In Korea, gas stoves using city gas or LNG are commonly used in Korea, and the cooking utensils are cooked by gas fire. At present, developed countries and parts of Korea are developing various types of electric ranges in order to avoid dangers such as fire.

In addition, microwaves using microwaves that simply heat frozen foods are also used, but this is not suitable for cooking and is mostly used only for warming.

Cooking utensils using these heat sources have a problem that the temperature is not constant and is too high to cause carcinogens by burning food if the cook is not careful. In order to solve this problem, a steam cooker using steam that has been raised only to a certain temperature has no concern about burning foods such as meat.

The steam cooker heats the heat source to produce steam and heats the hot plate to cook the food, so the hot plate does not heat up badly because the hot plate is not heated above the temperature of the steam. Of course, this cooker will burn if the food is on the grill for a long time.

These cookers provide a heat source and cook food using the heat source, and most of the cookers control the supply of the heat source to adjust the temperature at which the cook is cooked. In addition, there is a possibility to adjust the temperature, but this also does not directly control the heat source supply by sensing the temperature, but by studying how much the heat source is supplied in the product development to what extent the temperature is roughly determined and used It is nothing to do.

Therefore, a product that controls temperature precisely with home cooking utensils has not been developed.

The present invention has been made in order to solve the problems of the prior art described above, by detecting the temperature of the cooking plate is cooked by an infrared sensor to measure and keep the desired temperature set by the chef based on the detected temperature It is an object of the present invention to provide a cooker capable of automatic temperature control and a control method thereof.

The cooker capable of automatic temperature control according to the present invention includes a heat source for supplying heat to cook food, a cooker for cooking food based on heat supplied from the heat source, and an infrared sensor for sensing the temperature of the cooker. And a control unit for controlling the supply of the heat source according to the temperature sensed by the infrared sensor.

According to an embodiment of the present invention, a method of controlling a cooker capable of automatic temperature control may include determining whether a temperature is set by inputting a set temperature, determining the input temperature as the set temperature when the set temperature is input, and determining the set temperature. Heating the heater as a heat source; sensing the temperature of the cooking appliance through an infrared sensor while heating the heater; and if the detected temperature is lower than the set temperature, the heater is continuously heated and the temperature is continuously detected. Is determined to stop the heating of the heater when the temperature exceeds the set temperature, stopping the heating of the heater when the detected temperature exceeds the set temperature, and if the input switch is in the off position, the cooking is finished if the off position And returning the temperature to the step of sensing the temperature of the cooking appliance through the infrared sensor.

The cooker and its control method according to the present invention are optimal even if the same material is used because it detects the temperature of the cooking utensil on which the food is cooked using the infrared sensor and precisely controls the temperature of the cooking utensil. By providing a cooking temperature of the food to provide a more delicious cooking effect.

2 is a block diagram of a cooker block capable of automatic temperature control according to the present invention;
Figure 3 is a flow chart of a cooker control method capable of automatic temperature control according to the present invention.

Referring to Figure 1, the automatic temperature control cooker according to the present invention is a heat source for supplying heat to cook food, and the cooking utensil 20 to cook food based on the heat supplied from the heat source and Including an infrared sensor 40 for sensing the temperature of the cooking utensil 20, and a control unit 10 for controlling the supply of the heat source in accordance with the temperature detected by the infrared sensor 40. The heat source represents the heater 30, and the heater 30 is structured to obtain heat from electricity. The cooker 20 is mounted on the heater 30, and the cooker 20 is heated by heat generated from the heater 30. Steam inside the lower portion of the cooking sphere 20 is a heat medium oil. In other words, the steam warmed by the heater 30 enters the lower portion of the cooking zone 20 to heat the entire cooking zone 20.

The important point here is that when the cooking utensil 20 is heated using a heat medium such as steam, there is almost no temperature difference regardless of the center or the outside of the cooking utensil 20. That is, the temperature difference between the outside of the cooking zone 20 and the center is only 1 to 2 degrees. This is a very important factor in cooking. When cooking a pan or pan on a gas stove, there is a problem that the ingredients are cooked unbalanced when cooking due to a large temperature difference between the center and the outside.

The infrared sensor 40 is mounted on the lower portion of the cooking utensil 20 to sense the temperature of the cooking utensil 20 and transmit it to the control unit 10. The infrared sensor 40 is a sensor that detects a physical quantity or chemical quantity such as temperature, pressure, radiation intensity, etc. by using infrared rays, and converts it into an electrical quantity capable of signal processing. It can be measured. Since the entire area of the cooking zone 20 shows almost even temperature, the infrared sensor 40 can be widened in the available range, which is very advantageous in product design and design.

The controller 10 receives the temperature sensed by the infrared sensor 40 to control the heater 30 in various states. The control unit 10 includes a temperature input unit 11 for the user to input a temperature, and a window 12 for detecting and displaying the temperature received from the infrared sensor 40 is also provided.

The method for controlling the cooking apparatus 20 by the control unit 10 includes the step of determining whether the set temperature is input through the input unit 11 and the temperature is set (S1), and the set temperature is input through the input unit 11. When the input temperature is determined as a set temperature (S2), and if the set temperature is determined, the step (S3) of heating the heater 30 as a heat source, and the heater 30 while heating the infrared sensor 40 Step (S4) of detecting the temperature of the cooking port 20 through, and if the detected temperature is less than the set temperature continues to heat the heater 30 and continuously detects the temperature and the heater if the detected temperature exceeds the set temperature (30) determining to stop the heating (S5), and if the detected temperature exceeds the set temperature (S6) to stop the heating of the heater (30), and the input unit 11 detects whether the switch off position If it's in the off position, finish cooking. And it consists of the step (S7) that back to the step (S4) for sensing a cooking temperature sphere.

This control method can accurately control the cooking temperature of the cooking utensil 20 can be sensitive to the change in the temperature during cooking, otherwise it reduces the probability of seeing a failure.
