1 and 2, a top plate 10 forms an upper surface of a main body of the cooking appliance 1. [ And the casing 20 forms the remainder of the main body. That is, the casing 20 forms the front and rear surfaces and the both side surfaces and the bottom surface of the main body.

More specifically, the top plate 10 may be formed in a substantially rectangular plate shape. However, the shape of the top plate 10 is not limited thereto. For example, the top plate 10 may be formed in a disc shape. However, when the top plate 10 is formed into a disk shape, the shape of the casing 20 will be determined correspondingly.

A plurality of heat transfer openings (13) are formed in the top plate (10). The heat transfer opening 13 is substantially for transferring the heat of the heater 51, which will be described later, to the food. The heat transfer opening (13) is formed by cutting a part of the top plate (10). In FIG. 1, the heat transfer opening 13 is shown as being formed in a substantially circular shape, but the shape of the heat transfer opening 13 is not limited thereto.

In addition, a plurality of seating ends 15 are formed on the top plate 10. The seating end 15 is formed by a part of the upper surface of the top plate 10 corresponding to the inner periphery of the heat transfer opening 13 being stepped downward. A top glass 31 or a grill 41 to be described later is selectively seated on the seating end 15.

An input unit 17 is provided at the front end of the top plate 10. The input unit 17 receives signals for the operation of the cooking appliance 1 and the operation of the heater 51 substantially. In addition, in the present embodiment, the input section 17 receives a signal for turning the heater 51. At this time, the input unit 17 can input a signal for rotating the heater 51 in the form of cooking by the user, for example, in the form of cooktop cooking or grill cooking. Of course, the input unit 17 may be provided on the front surface of the casing 20. [

The casing (20) is formed in a polyhedral shape having a substantially upper surface opened. In this embodiment, the casing 20 is formed in a flat hexahedron shape having a substantially upper surface corresponding to the shape of the top plate 10. Therefore, the shape of the casing 20 may be formed in various shapes according to the shape of the top plate 10. FIG.

An inlet / outlet 23 is formed on the front surface of the casing 20. The inlet (23) is formed by cutting a part of the front surface of the casing (20). The input / output port 23 is a place where a collecting tray 65, which will be described later, enters and exits the inside and the outside of the casing 20.

A top glass 31 and a grill 41 are selectively mounted on the heat transfer opening 13. For this purpose, the top glass 31 and the grill 41 are formed in a shape corresponding to the heat transfer opening 13. The bottom edges of the top glass 31 and the grill 41 are supported on the seating end 15 in a state of being mounted on the heat transfer opening 13 substantially. On the top surface of the top glass 31, in the case of a cooktop cooking, the container containing the food, substantially the food, is seated. On the upper surface of the grill 41, the food is seated in the case of grill cooking. At this time, the top glass 31 may be substantially formed of the same material as the top plate 10. For example, the top plate 10 and the top glass 31 may be formed of a ceramic glass material having predetermined strength and heat resistance. The grill 41 is generally similar to a grill used for grill cooking.

However, in the present embodiment, in a state where the top glass 31 is mounted on the heat transfer opening 13, that is, in a state where the bottom edge of the top glass 31 is seated on the seating end 15, The upper surface of the top glass 31 protrudes upward relatively to the upper surface of the top plate 10. This is to prevent the overflowing food from staying on the top surface of the top glass 31 in the process of heating the food contained in the container placed on the top surface of the top glass 31.

On the other hand, various components constituting the cooking appliance 1 are installed in the casing 20. In the present embodiment, a plurality of heaters 51, a plurality of driving sources 61 (see FIG. 3), and a control unit 63 (see FIG. 3) are provided in the casing 20.

More specifically, the heater 51 serves as a heating source for providing energy for cooking the food. The heater 51 heats the cooked food placed on the upper surface of the grill 41 by heating the container containing the food placed on the top surface of the top plate 10 to cook the cooked food, Perform grill cooking.

At this time, the heater 51 heats the food in either the first position A (see FIG. 4) or the second position B (see FIG. 5). Accordingly, the heater 51 substantially rotates by an angle corresponding to the angle between the first and second positions A and B, respectively. Here, the first position A means a position at which the area of overlap of the projections in the vertical direction of the heat transfer opening 13 and the heater 51 is increased compared to the second position B. In other words, the heater 51 shields the entire heat transfer opening 13 in the vertical direction at the first position A and a part of the heat transfer opening 13 at the second position B It can be said that it is shielded. In the present embodiment, the heater 51 is located at the first position A in the case of the cooktop cooking and at the second position B in the case of cooking the grill.

For example, in the first position (A), the heater (51) is parallel to a virtual plane in which the heat transfer opening (13) is located, and in the second position (B) The heat transfer opening 13 can be inclined at a predetermined angle with respect to a virtual plane in which the heat transfer opening 13 is located. Preferably, at the second position B, the heater 51 may be inclined at an acute angle with respect to a virtual plane in which the heat transfer opening 13 is located. In other words, the shortest distance between the tip of the heater 51 and the imaginary plane at which the heat transfer opening 13 is located is shorter at the first position A than the second position B .

This is because the energy generated in the heater 51 substantially located at the second position B is sufficiently transmitted to the food placed on the upper surface of the grill 41 through the heat transfer opening 13 . The angle between the imaginary plane in which the heat transfer opening 13 of the heater 51 is located at the second position B is inclined at an acute angle, The amount of energy of the light source 51 may be reduced

The shape of the heater 51 may be various. For example, the heater 51 may be bent at least once so as to be formed into a substantially tubular shape. Also, the heater 51 is generally formed in a bar shape, and a plurality of the heaters 51 may be arranged in the longitudinal direction to form one heating source as a whole.

Further, a reflection plate 53 is provided below the heater 51. The reflection plate 53 is disposed on the top glass 31 and the grill 51 which are mounted on the heat transfer opening 13 so that the energy of the heater 51, for example, light and / And reflects the food to the food placed on any one of them. In the present embodiment, the reflection plate 53 is rotated together with the heater 51.

Referring to FIG. 3, the driving source 61 provides a driving force for rotating the heater 51. As the driving source 61, for example, a stepper motor rotatable in both directions can be used

Meanwhile, the control unit 63 controls the operation of the cooking appliance 1, and substantially the operation of the heater 51 and the driving source 61. The control unit 63 drives the driving source 61 so that the heater 51 is positioned at the first position A when the input unit 17 receives a signal for selecting the cook top cooking. The control unit 63 operates the driving source 61 so that the heater 51 is positioned at the second position B when the input unit 17 receives a signal for selecting the grill cooking.

Referring again to FIGS. 1 and 2, a collecting tray 65 is installed so as to be housed inside and outside the casing 20. The collecting tray 65 is for collecting foreign substances such as oil which are generated in the course of cooking the food placed on the upper surface of the grill 41. For this purpose, the collecting tray 65 may be formed in a shape and size that can shield at least the entire heat transfer opening 13. The collecting tray 65 is inserted into and discharged from the casing 20 through the inlet /
