The present invention relates to a microwave oven that does not require a tray driving on / off relay, more specifically, it is possible to cook food by inserting a long food in the left and right direction and a long plate in the cooking chamber without stopping the tray. The present invention relates to a microwave oven which does not require a tray driving on / off relay which can reduce manufacturing costs by eliminating a relay by turning off the operation of the circular tray.

In general, a microwave oven that cooks food by dielectric heating using frictional heat caused by the translational motion of water molecules contained in the food by irradiating the food with ultra-high frequency generated from the magnetron has a high cooking efficiency. It is widely used because it can drastically shorten and reduce the loss of nutritional value during food cooking, thawing and warming.

On the other hand, recent microwave ovens are equipped with a heat transfer heater and a convection pan using resistance heat in the cooking chamber, so that food can be cooked at a very high frequency like a conventional microwave oven, and the surface of the food can be directly heated by the heat of the heat transfer heater. By heating it is possible to cook foods that require browning on the surface, such as bread, fish and barbecue.

Figure 5 is a perspective view of a microwave oven according to the prior art, Figure 6 is a partial cross-sectional view showing a state in which the tray is installed in the tray mounting portion in FIG.

As illustrated in FIGS. 5 and 6, the microwave oven includes a cooking chamber 110 for providing a food storage space and a cooking space, and the door 150 is opened and closed at the front of the cooking chamber 110. Combined.

The cooking chamber 110 is supplied with a microwave generated from the magnetron installed in the electric field chamber (not shown) to heat the contents therein.

On one side of the cooking chamber 110, a control panel 120 having a plurality of buttons for controlling the operation of the microwave oven 100 while selecting a function of the microwave oven 100 is coupled to the front side.

The tray seating part 114 is formed in the bottom plate 112 of the cooking chamber 110 so that the disc-shaped tray 130 on which the cooking container and food are seated can be installed.

As shown in FIG. 6, a tray motor 140 for rotating the tray 130 is installed in a central area of the rear surface of the tray seating part 114.

In the microwave oven 100 configured as described above, when the microwave oven 100 is operated, the microwaves generated from the magnetron are irradiated to the cooking chamber 110 and the tray 130 is rotated at a low speed by driving the tray motor 140. Food placed on the tray 130 is cooked by high frequency.

However, in the microwave oven 100 configured as described above, as described above, the cooking chamber 110 is formed in a square shape, and the tray 130 is formed in a circular plate, so that the cooking chamber 110 is actually used to heat food. The area of) corresponds to a circle occupied by the tray 130, which makes it difficult to add a long type of food in the left or right direction or an oblong dish long in the left and right directions.

That is, since the width of the cooking chamber 110 in the front and rear direction is narrower than the width in the left and right directions, the rotation is affected by the front and rear of the inside of the cooking chamber 110 when the food is rotated or the long plate is loaded. It was not smooth.

In order to compensate for this problem, when food or a long dish of a long length in the left and right directions is put, the food tray is cooked after being turned off (stopped) so that the circular tray 130 cannot be rotated. To this end, the drive of the tray motor 140 must be turned off (stopped) by using a separate relay, which increases the number of parts and increases the manufacturing cost of the microwave oven.

The present invention has been made to solve the problems of the prior art as described above, the technical problem of the present invention can cook food by putting a long food in the left and right direction and a long plate without stopping the tray, The purpose of the present invention is to provide a microwave oven that does not require a tray driving on / off relay which eliminates the need for a relay by turning off the operation of the circular tray.
