The present invention relates to an oven cooker equipped with a far-infrared tube heater, and in particular, by radiating far-infrared rays together with heat in a ceramic tube to increase thermal efficiency, shorten the cooking time and completely cut off the motor and the heating part to prevent the breakdown of the motor as well as the expansion ring. It can be used to increase the internal volume of the oven cooker arbitrarily, and there is no fear of contamination of the blower fan, and relates to an oven cooker which can be easily cleaned without the need for separate cleaning.

Oven cookers typically used in conventional homes have been used in combination by using a gas stove indirectly cooked using gas and an oven cooked directly using electric heat. However, a conventional oven cooker composed of a gas stove and an oven in combination is large and expensive, and even when cooking a small amount of heat, a large amount of heat is consumed, resulting in deterioration of thermal efficiency and inconvenience of internal cleaning. In addition, in recent years, various types of oven cookers have been proposed to solve the problems of the hybrid oven cooker as described above.

In this proposal, U.S. Patent No. 4,350,874 discloses a case member removably installed on a stepped surface of a peripheral wall portion of a base portion to form a cooking chamber in a case member and a base portion, and a heat generator and heat installed in a heating chamber to transfer the cooking chamber to the cooking chamber. It consists of a heating air fan installed in a heating chamber, and a cooling fan provided in the radiation chamber adjacent to the said heating chamber.

The above-mentioned oven cooker cooks the food by cyclone hot air at high speed in the cooking chamber by heating air fan, so that the hot air is in uniform contact with the food. The noise has to be rotated, so the life of the motor was shortened.

In addition, since the heating air fan is located almost in line with the upper surface of the case member, the hot air cyclone by the heating air fan is in direct contact with the upper surface of the case member, and because the temperature in the cooking chamber is high, the upper member is used to take out the cooked food. There was a risk of burning my hands when I opened it.

As another proposal, U.S. Patent No. 4,817,509 is provided with an upper end member having a circular horizontal cross section and a blowing fan installed in the center hole of the upper member and a heating means on the upper part of the blowing fan.

The oven cooker also allows the hot air to be cyclone at the high speed in the cooking chamber by the blowing fan to heat the hot cyclone evenly in contact with the cooking to reduce the thermal efficiency as well as cooling means for cooling the high heat of the motor There was a need for complex structures as needed.

In addition, since the upper surface of the upper member is horizontal and the lower end of the blowing fan that blows the hot air is positioned on the same line as the upper surface, the hot air blown by the blowing fan directly touches the upper surface of the upper member so that the upper surface of the upper member melts or When opening the top member to take out cooked food, there was a fear of dale.

In addition, since the blowing fan is installed under the heating means and exposed in the cooking chamber, the cooked food is splashed and there is an inconvenience of separating and cleaning the blowing fan when cleaning the cooker.

As another proposal, U. S. Patent No. 5,165, 328 forms a cooking chamber with an upper sealed barrel member, an extended rim and a lower sealed cylinder member, and a hinge support composed of a means for heating air in the cook chamber and an upper support, an extension and a lower end. It consists of an assembly.

The oven cooker also has a hot air directly in contact with the upper airtight container member, there is a concern that the upper surface of the upper member melts or the hand dale, there was a inconvenience to separate and clean the blower fan when cleaning the external cooker. In addition, the extension ring for expanding the cooking chamber was formed as a single body, so that it was difficult to store and there was a risk of damage during storage, and one extension ring could be divided into two prefabricated extension rings to be assembled with a clip. When storing the extension ring and the clip of the dog, there is a risk of losing a small clip, as well as using a separately manufactured clip, the assembly is not strong, and it is very inconvenient to disassemble and assemble. In addition, the upper support is attached to the housing, so even when the interconnect member is not necessary, it is inconvenient to use the cooker.

In view of the above, the present invention uses a ceramic heating tube as a heating means and installs a blower fan on the upper portion of the ceramic heating tube, so that the permeable far-infrared rays emitted from the ceramic heating tube emit heat generated by the heating wire in the ceramic heating tube. As it is directly transmitted through to the inside of the food, the heat is evenly delivered and cooked, which is completely different from the method of cooking food by cyclone at high speed, which is a conventional oven cooker assembly method as described above, which saves cooking time and heat efficiency. It is high.

Another object of the present invention is to install a blowing fan that rotates at a low speed in order to ensure that the heat inside the cooking chamber is evenly mixed in the heater base, thereby preventing the splashing of the flag or dirt in the cooking chamber, thereby disassembling to the blowing fan when cleaning the cooker. It is to wipe out the hassle that needs to be cleaned.

Another object of the present invention is to form an inclined surface on the upper surface of the hood and to install the ceramic heating tube in the lower portion of the inclined surface by installing the ceramic heating tube in the upper portion of the inclined surface by the blower fan to the air convection by the blower fan on the upper surface of the hood It is to prevent the hood from melting by preventing direct contact, and to secure the space between the cover and the hood when holding the handle of the cover to prevent the hand from falling.

Another object of the present invention is to prevent the motor life from shortening by preventing the motor from overheating by blocking the heat between the motor and the heat generating portion by the mica plate to block the heat of the heat generating portion to the motor.

Another object of the present invention is to make it convenient to use by adjusting the volume of the cooking chamber arbitrarily by using an extended amount separated by the amount of food to be cooked.

Another object of the present invention is to remove the stand from the cooker configured to fold the cover to reduce the inconvenience in use and storage, and to purchase only the cooker for users who do not need the stand By expanding the range of the user's choice by explaining in detail based on the accompanying drawings as follows.

In this cooker, as shown in FIGS. 1 to 3, a cover 1 having a heating means built therein, a hood 16, and a container 23 are formed so that a cooking chamber is formed. And the mica plate 7 is inserted into and installed in the cover 1 in which the electric parts are wrapped in the heat insulating material 1 ', and the heater base 8 is fixedly installed at the lower part of the mica plate 7. The heater chamber 10 is installed in the insertion hole 8 'of the mica plate 7 so that the spacer 9' is formed by the spacer bar 9, and the aluminum material is blocked in the heater chamber 10. Inserting the plate 40, the riveting so that the spacer 42 is formed by interposing the spacer 41 between the heater chamber 10 and the blocking plate 40, the thermal sensing rod connected to the thermostat ( 43 is installed in the blocking plate 40 through the heater lever 10, and the blower fan 11 is fixed to the motor shaft 3 ', and the heating wire 13 is built in and the bush 14 is installed on both sides. Shut off ceramic heating tube (12) Inserted into the insertion hole (10 ') perforated on both side walls of the heater chamber (10) through the 40, the guard net 15 is mounted to the lower portion of the ceramic heating tube 12, the heater base (8) The upper surface of the hood 16 is inserted into the inclined surface 17 is formed.

Bushes 14 provided on both sides of the ceramic heating tube 12 serve as an insulating material.

Therefore, the air heated by the ceramic heating tube 12 is blown into the cooking chamber by the low-speed blower fan 11, and the far infrared rays emitted from the ceramic heating tube 12 are projected to the cooking chamber. Because of its size, it is projected to the inside of the food and transfers heat to the food, so the cooking time is shortened and the food is cooked evenly so that the cooking temperature can be lower than the conventional high speed cyclone cooking method, which only depends on the convection method. .

At this time, the far-infrared rays emitted upward from the ceramic heating tube 12 are inserted into the heater chamber 10 by the aluminum blocking plate 40 riveted to form the separation portion 42 by the spacer 41. Since the reflected light is emitted into the cooking chamber, the thermal efficiency is further increased, and far infrared heat is not transmitted to the motor 3. That is, the aluminum blocking plate 40 serves to protect the motor 3 while increasing the thermal efficiency by reflecting far infrared rays into the cooking chamber.

When the temperature of the cooking chamber heated by the ceramic heating tube 12 reaches the set temperature, it is preferable to cut off the power of the ceramic heating tube 12 by the thermostat 6 to which the heat sensing rod 43 is connected. The blowing fan 11 is continuously driven to condense the residual heat into the cooking chamber.

The frying pan 22 collects grease, etc. of the cooked food during cooking, and the cooked food is placed on the bucket 21 so that heated air touches the lower part of the cook pan to cook the food evenly within a short time.
