Internal base plate and tray structure for hot air dispersion of microwave oven {A BASE PLATE AND TRAY STRUCTURE FOR HEAT DISPERSION IN MICROWAVE OVEN}

The present invention relates to a microwave oven, and more particularly, to an internal bottom plate and tray structure for dispersing hot air of a microwave oven to disperse hot air into a bottom portion of a food when cooking a convection of a microwave oven.

In general, during the convection cooking of the microwave oven, the foods placed on the tray are cooked by convection heat, and the heat radiated from the heater forms convection heat through the convection pan or the reflector. This structure will be described in detail with reference to the accompanying drawings.

1 is a partial cross-sectional view for explaining a partial function of a general microwave oven. The microwave oven 100 referring to FIG. 1 is installed on the inner side of the interior chamber 121 and has a rear plate 103 provided with an outlet port 113 and an inlet port 115 so that hot air can be convexed, and the rear plate. The heater 123 is provided to the outside of the 103, and the convection fan 125 and the motor 107 for convection the heat generated from the heater 123 are fixed to the outer plate 105.

And the inner bottom plate 101 of the inner chamber 121, the inner bottom plate 101 is bent according to the rotation and the flow radius of the roller 111 and seated on the roller 111 and cooked A tray 117 to settle the water 119 and a tray botter 109 for rotating the tray 117 are mounted at the center portion of the inner bottom plate 101.

Hereinafter, the operation according to the above configuration will be described.

First, the user selects a convection mode using the microwave oven 100 and controls a predetermined function to roast or cook the food 119. At this time, the food 119 is placed in the tray 117, the cooking function is performed according to the user's key selection, the power is supplied to the heater 123 and at the same time the operation of the motor 107 and the convection fan 125 ) Rotation is started, and the tray motor 109 is driven to form convection heat by the convection fan 125 together with the rotation of the food 119.

That is, when heat is generated by the heater 123 provided on the outer side of the inner plate 103, the convection fan 125 attracts the air in the chamber 121 to the suction port 115 and at the same time the discharge port 113. The air heated by the heater 123 is discharged into the chamber 121. Therefore, the chamber 121 is heated by convective heat to cook the food 119.

And the tray motor 109 is driven to make this cooking smooth, the tray 117 is rotated by the drive of the tray motor 109, the tray 117 is supported on the roller 111, the inner bottom The plate 101 is rotated with a predetermined trajectory according to the bending shape of the plate 101. Therefore, the food 119 is rotated from the tray 117 is rotated to evenly cook.

However, since the hot air that is convection during roasting or convection cooking is mostly transmitted to the upper end of the food 119 placed in the tray 117, only the remaining portion of the food 119 except for the bottom portion is cooked. That is, the hot air convection by the convection fan 125 may not penetrate sufficiently between the tray 117 and the inner bottom plate 101 through the discharge port 113 provided at the lower end of the inner plate 103. You will not be able to heat the bottom. Therefore, when the convection cooking mode of the microwave oven is a situation in which the bottom surface of the cooking chamber of the microwave oven can be transferred to the bottom portion of the food 119.

The present invention was devised to solve such a problem, and an object of the present invention is an inner bottom plate and a tray for hot air dispersion of a microwave oven in which convective heat can be dispersed to the bottom of the food during roasting or convection cooking mode of a microwave oven. In providing a structure.

The inner bottom plate structure for dispersing hot air of the microwave oven according to the first aspect of the present invention for achieving the above object is installed on the inner bottom surface of the high chamber room so that the tray is seated so as to disperse the hot air during the convection cooking of the microwave oven. In the inner bottom plate structure, the inner bottom plate is formed in a semi-circular shape downwardly by the distance to the roller rotation radius with respect to the drive shaft of the tray motor, separated by the inclined surface into the reference surface and the bottom surface, both ends of the semi-circular shape However, the bottom surface and the reference surface extend in the rear direction with respect to the drive shaft of the tray motor, characterized in that to form a protruding forming surface of a circular shape upward to allow the tray motor to be seated inward.

In addition, the inner bottom plate structure for hot air dispersion of the microwave oven according to the second aspect of the present invention for achieving the above object, by raising the inner bottom plate to the upper side of the inner plate to the flange (Flangeing) to combine the bottom surface of the inner plate Located in the center of the discharge port provided in the lower end, the bottom surface close to the inner plate is formed with a dispersion port formed a plurality of balls, the guide duct so that the air discharged from a portion of the discharge port is injected into the bottom surface of the tray through the distribution port It is characterized by the configuration.

In addition, the tray structure for dispersing hot air microwave oven according to the third aspect of the present invention for achieving the above object, the tray is formed a plurality of inlets in the side portion, the bottom surface to form a plurality of the same shape, A bottom inlet of the same shape is formed inwardly of the formed shape.

Hereinafter, the present invention will be described in detail based on the accompanying drawings.

2 is a partial cross-sectional view of the microwave oven according to the first embodiment of the present invention. The microwave oven shown in FIG. 2 is installed at the inner bottom surface of the interior chamber 225 of the microwave oven, and is installed at the rear of the microwave oven chamber 225 on which the tray 223 is seated. An inner plate 203 having an inlet 215 and an outlet 213, an outer plate 205 fastened with a predetermined space to the outside of the inner plate 203, and an inner side portion of the outer plate 205. The heater 209 is fixed to the bottom and fixed to the center portion of the outer plate 205 to introduce the air in the chamber 225 through the inlet 215 and to discharge the air introduced through the outlet 213 And a motor 207 for driving the convection fan 211 and the convection fan 211. Unexplained reference numeral '217' is a tray motor, '219' is a roller, and '221' is a food.

On the other hand, the inner bottom plate 201 is formed in a semi-circular form downwardly by the distance to the rotation radius of the roller 219 forward with respect to the drive shaft of the tray motor 217, the reference surface 231 by the inclined surface 235 ) And the bottom surface 233, and extend the bottom surface 233 and the reference surface 231 in the rearward direction with respect to the drive shaft of the tray motor 217 at both ends of the semicircular shape, and the tray motor 217 to the center portion. Protruding forming surface 237 of a circular shape is formed upward so that it can be seated inward.

Hereinafter, the operation of the above configuration will be described.

When cooking is performed in a state in which the food 221 is placed, the motor 207 receives power to rotate the convection fan 211. This introduces air into the interior chamber 225 into the inlet 215 provided in the inner plate 203 and discharges the air introduced through the outlet 213. At this time, as the air is heated together with the operation of the heater 209, the chamber 225 is heated by convective heat to cook the food 221.

On the other hand, the air discharged through the discharge port 213 is introduced into the lower end of the tray 223 through the formed bottom surface 233 of the inner bottom plate 201. This evenly heats the lower end of the tray 223 by the rotation of the tray 223.

Therefore, the cooking 221 is cooked by convection heat and at the same time, the convection heat is transferred to the lower end of the tray 223 so that the food 221 is generally cooked.

Then look at the configuration according to a second embodiment of the present invention.
