Description

Barbecue device of microwave-oven

The present invention relates to a microwave oven, and more particularly to a roasting apparatus of the microwave oven.

In general, the microwave oven is an outer case (10) surrounding the outer periphery of the body 100, as shown in Figures 1 and 2, and the food cooking space located on the inner side of the body (100) 20 And, located on the other side of the inside of the body 100 is made up of the electrical equipment room 30 is a variety of components necessary for the operation of the microwave oven.

The interior 20 has the following components in detail.

The food 230 is placed and the tray 21 for rotating the food, the heater 22 for dissipating heat to bake the food and the tray 21 so that the food can receive the maximum heat of the heater 22 It consists of a grill rack (grill rack) 200 to be seated on.

In addition, the electrical equipment room 30 has the following components in detail.

Transformer (32) for converting the general voltage coming into the home to the high voltage required for the magnetron (31) oscillation, and a series of cog wheels forming a cathode and a cathode, the anode surrounds the cathode, The magnetron 31 generates a microwave (2,450 MHz) as the emitted electrons are prevented from reaching the + pole by the magnet, and the magnetron 31 generates considerable heat while the above-described action continues. It consists of a cooling fan 33 for cooling it, and a microwave guide 34 for moving the microwaves generated from the magnetron 31 to the inside of the refrigerator 20.

Therefore, the microwave oven having such a configuration oscillates microwaves from the magnetron 31 by using the magnetron 31 to control the current by applying a magnetic field, and the oscillated microwave is placed on the tray 21 of the inside of the refrigerator 20. By reacting with the molecules of the food 230 present, the food is cooked by the frictional heat generated from the interaction.

The details of the roasting apparatus in the microwave oven having the above configuration and operation will be described in more detail with reference to FIGS. 2 and 3.

The first prior art has a plurality of feet 220 to be placed on the tray 21 as a gill rack (200) as shown in Figure 1, the top of the feet 220 food It is a roasting apparatus of the microwave oven, which can be put on the grill 210 is integrated.

When roasting using the grill rack 200 as described above, when the food 230 is placed on the grill 210 and the roasting is performed, the heater 22 located on the upper part of the refrigerator 20 is operated to support the food at the same time. The grill rack 200 rotates to the left-right direction by the tray 21 (refer to the arrow).

However, the prior art has the following problems.

Since the grill rack 200 performs only left and right rotational movements, the side facing the heater 22 of the food 230 is cooked evenly while the side opposite to the heater 22 is not ripe, so that the door of the body 100 is roasted. Take out the food 230 and take out the food directly by the consumer to flip the food during cooking inconvenient in using the food, and the roast time is long due to heat loss caused by opening and closing the door of the body 100 to flip the food The problem is losing.

As shown in FIG. 3, the second conventional technology includes a motor 320 capable of driving the food and a microcomputer (not shown) capable of controlling the motor and a program of the microcomputer as shown in FIG. 3. The bracket 340 is installed so that the microcomputer switch 330 to initialize the fixed.

And the heater 22 for dissipating heat to food is provided on the inner wall of the upper surface portion of the inside of the refrigerator 20, and rotates under the driving force of the motor 320 on one side of the interior of the refrigerator 20 by a microcomputer switch. The rotating body 310 in which a position is initialized is provided.

A shaft support 350 is formed on the opposite inner wall of the rotor 310 on the same line as the rotor 310, and has two rotisserie-bars having an iron skew shape and integrated with food 230. 300 is a microwave oven roasting device is fitted to the rotary body 310 and the shaft support 350.

When the food is installed, the rotiba 300 starts to roast and uniformly bakes the food while continuously rotating (see arrow) by the motor 320.

However, the prior art has the following problems.

Since the food continues to rotate during the roasting of food, roasting a whole chicken such as chicken is suitable, but not suitable for a thin-shaped dish in which radiant heat of the heater must be concentrated on the upper and lower surfaces.

That is, since the food continues to rotate, radiant heat that needs to be concentrated on the upper and lower surfaces is radiated to the side of the food in the same way, resulting in large heat loss.

In addition, since the rotiva 300 fitted to the rotor 310 and the rotiva 300 fitted to the shaft support 350 have a structure separated from each other, the rotiva receiving the driving force of the motor 320 directly ( 301 may continue to rotate, but the rotiva 302 fitted to the shaft support 350 is rotated by the driving force transmitted by the food 230, so when roasting the soft food without the skeleton rotiva 301 There is a problem that the food 230 is separated at 302.

In addition, when the food 230 is cooked after being inserted into the rotiva 300, the food is contracted and deformed by heat, and the food is separated from the rotiva 300.

In addition, only food that can be plugged into the rotiva 300 can be cooked, so the food that can be roasted is limited.

The present invention has been made to solve the above problems, the grill is adjusted to the size of the food to prevent food from being released from the grill by the rotation of the grill and food shrinkage by heat can be fixed to the grill food Therefore, the purpose of this is to install the grill in which the food is accommodated so as to be able to receive radiant heat according to the type or shape of the food so as to be rotated at an arbitrary angle.

When power is applied to the body 100, the motor 610 rotates to move the microcomputer switch 620 to initialize the position of the rotor 310 having a semi-circular groove to round the bottom of the groove of the rotor 310. To face (S10).

In addition, the program of the microcomputer (not shown) is initialized (S10).

When the rotary body 310 is initialized, the round portion of the semi-circular shaft 439 formed on the body grill 400 is inserted into the round portion of the rotary body 310 as shown in FIG. When the 449 is seated on the shaft support 350 of the in-vehicle 20, the cover grill 500 side of the grill 700 faces the heater 22 (S20).

After that, by pressing the roast button (not shown) (S30), the heater 22 is heated (S40).

Thereafter, it is determined whether to select a manual roasting mode for manually roasting the food or to select an automatic roasting mode for automatically (S100).

When the automatic roast mode is selected, two modes are selected again.

Depending on the type of food it is determined whether to select the inverted roasting mode to perform the 180 ° inverting function, or to select the roasting mode that requires continuous rotation (S110).

First, when the consumer selects the reverse roast mode, it works as follows.

The food continues to absorb the radiant heat of the heater until the inverted period already set by the experimental value at the initialized position (S210).

When the inversion cycle is reached, the grill rotates 180 ° and flips the food (S220).

In the food inverted state continues to absorb the radiant heat of the heater until reaching the roasting time already set by the experimental value (S230).

And the three steps (S210) (S220) (S230) are repeated by the experimental value set according to the type of food.

After the repetition of the heater is turned off (S50), the food roasting is completed.

Second, when the consumer selects the roasting mode, it works as follows.

The grill continues to rotate 310 until reaching the roasting time already set by the experimental value (S320).

The grill is stopped when the set roasting time is reached (S330).

And the heater is turned off (S50), food roasting is completed.

Third, when the consumer selects the manual roast mode, it operates as follows.

In the manual relationship, the consumer first sets the roasting time by pressing the setting key (S410), and sets the rotation angle of the desired food (S420).

The grill is rotated up to the set rotation angle (S430), and the grill is stopped when the rotation angle is reached (S440).

And the consumer can re-enter the rotation angle to suit the food repeatedly (S450).

When reaching the set roasting time (S460), the heater is turned off (S50), the food roasting is completed.

Other dishes can be rotated and stopped periodically.

As described above, the present invention can prevent food from being released from the grill by deformation such as shrinkage when grilling the food because the grill is adjusted to suit the size of the food.

And it can be rotated at any angle so as to absorb the radiant heat according to the type and shape of food can reduce the heat loss accordingly.

In addition, the cooking time can be reduced by about 40% to 60% by giving an appropriate radiant heat depending on the type of food.
