Description

microwave

The present invention relates to a microwave oven, and more particularly, to a cooking plate for a microwave oven on a rectangular plate seated on the bottom surface of the cooking chamber.

In general, a microwave oven is a mechanism in which food is cooked by frictional heat between molecules by repeatedly converting a molecular array of moisture contained in a food to radiate a high frequency of 2450 MHz in a magnetron into a cooking chamber. Recently, various models have been proposed. 1 is a perspective view showing a monitor look type (MONITOR LOOK TYPE) microwave oven.

In the monitor look type microwave oven, a cooking chamber 2 is formed in an upper part of a cabinet 1 on a rectangular parallelepiped forming an appearance, and an electrical equipment room (not shown) is provided in which a plurality of electrical equipments are installed in the lower part.

The electronics compartment has a magnetron (not shown), a high voltage transformer (not shown), and a control device (not shown) that emit high frequency radiation to the cooking chamber, and there are a number of operations for setting cooking conditions of the microwave. The control panel 4 provided with the button 5 is mounted.

One side of the cooking chamber 2 is open, and the door 6 for opening and closing it is coupled to the cabinet 1 through a hinge member so as to be rotatable. The cooking dish 3 is installed inside the cooking chamber 2. The cooking plate 3 consists of a rectangular plate of glass material and is seated on the bottom surface of the cooking chamber 2.

Therefore, when the user puts food on the cooking plate 3 and operates the microwave oven through the operation button 5 in a state in which the door 6 is closed, high frequency radiation is emitted from the magnetron to the inside of the cooking chamber 2, whereby The cooked food is cooked by the frictional heat generated as the molecular sequence of water is rapidly converted.

However, such a conventional monitor look type microwave requires a great deal of care when the cooking dish 3 on which the workpiece is placed is not firmly fixed and is installed in a flowable manner. That is, the cooking dish 3 is simply placed on the bottom of the cooking chamber 2 without a separate fixing means so that the front and rear right and left flows are possible, and thus the cooking dish 3 is freely installed in the process of placing food on the cooking dish 3 ( 3) is pushed from the bottom of the cooking chamber (2) there is a problem that the food is not placed safely.

The present invention is to solve this problem, an object of the present invention is to form a pair of fixed grooves formed concave on the bottom surface of the cooking chamber on which the cooking plate on the rectangular plate is seated at regular intervals, the fixed groove on the lower surface of the cooking plate By configuring a pair of fixing protrusions to be inserted into the cooking plate, the cooking plate is firmly seated on the bottom surface of the cooking chamber to provide a microwave oven in which its flow is prevented.

In order to achieve the above object, the present invention provides a microwave oven having a cooking plate in which a cooking chamber is cooked in which high frequency radiation is radiated inside, and a cooking plate in a square plate seated on the bottom of the cooking chamber, where the food is placed.

At the rear side of the bottom of the cooking chamber, a pair of recessed grooves are formed to be concave at regular intervals.

The lower portion of the cooking plate is characterized in that a pair of fixing projections are inserted into the fixing groove to prevent the flow of the cooking plate.

Hereinafter, one preferred embodiment according to the present invention will be described in detail with reference to the accompanying drawings.

2 is a perspective view showing a microwave oven of the monitor look type according to the present invention, Figure 3 is a cross-sectional view showing a seating state of the cooking dish.

As shown in the monitor look type microwave oven according to the present invention, the cooking chamber 20 is formed in the upper space of the cabinet 10 having a rectangular hexahedral shape, so that the electrical equipment compartment (not shown) is partitioned in the lower space. To be prepared.

In the electrical equipment room, a magnetron (not shown) that emits high frequency radiation to the cooking chamber 20 and a high voltage transformer (not shown) that applies a high voltage to the magnetron are embedded, and a control panel 40 is provided on the front part thereof. . On the front of the control panel 40, a plurality of operation buttons 41 are configured as a means for manipulating the cooking stroke, and on the back, a circuit board (not shown) for operating a microwave through a signal input through the operation button 41. Is fitted.

And the door 50 for opening and closing the cooking chamber 20 is coupled to the front surface of the cabinet (10). One end of the door 50 is rotatably coupled to the cabinet 10 through a hinge member, and the other end is formed with a clasp 52 and a handle 51 for maintaining a locked state.

On the other hand, inside the cooking chamber 20 is provided with a cooking dish 30 to place the food. Cooking plate 30 is made of a rectangular plate shape of the glass material that the high-frequency transmission, and a fixed protrusion 31 is provided to prevent the front and rear left and right flow as a characteristic element of the present invention, the structure of the following will be described in more detail Same as

First, the pair of fixing grooves 22 recessed in the bottom surface 21 of the cooking chamber 20 are formed. The fixing groove 22 is spaced apart at regular intervals on the rear side of the bottom surface 21 of the cooking chamber 20 and configured side by side. And the lower portion of the cooking plate 30 is provided with a pair of fixing projections 31 are inserted into the fixing groove 22, which is also provided so that the tip is protruded downward on the rear side lower surface of the cooking dish 30. Therefore, when the cooking plate 30 is placed on the bottom surface 21 of the cooking chamber 20, the fixing protrusions 31 are inserted into the fixing grooves 22, respectively, thereby preventing front, rear, left, and right flow of the cooking plate 30. Reference numeral 32 is a locking step provided on the front side of the cooking dish 30.

Next will be described the operation and effect of the microwave oven according to the present invention configured as described above.

First, a container containing food or food is placed on the cooking dish 30 securely seated on the bottom surface 21 of the cooking chamber 20. When the microwave oven is operated by operating the operation button 41 provided on the front of the control panel 40 while the door 50 is closed, high frequency radiation is emitted from the magnetron to the cooking chamber 20. The food irradiated at such a high frequency is uniformly cooked by the heat of friction due to the rapid molecular transformation of water.

After the cooking is completed and the operation is stopped, the handle 50 of the door 50 is pulled forward and the latch device 52 is pulled out, and the door 50 rotates clockwise around the hinge member. The front part is opened, and the food placed in the cooking dish 30 is taken out through this.

The cooking dish 30 on which the food of the microwave is placed is firmly seated on the bottom surface 21 of the cooking chamber 20 by using the fixing groove 22 and the fixing protrusion 31 as a characteristic element of the present invention. This prevents flow during the loading or unloading of food.

As described in detail above, the microwave oven according to the present invention has a pair of fixing grooves formed concave on the bottom surface of the cooking chamber in which the cooking plate on the rectangular plate is seated at regular intervals, and the lower surface of the cooking plate has a fixed groove. A pair of fixing protrusions protrude downward to be inserted.

Therefore, when the cooking plate is placed on the bottom of the cooking chamber, the fixing protrusions are inserted into the fixing grooves, respectively, thereby preventing the flow of the left and right, and the workpieces are firmly seated, and overall product reliability is improved.
