Description

Microwave oven with negative ion generator

The present invention relates to a microwave oven having an anion generating device, in particular, when starting cooking and after cooking is completed to drive the anion generating means with a cooling fan to deodorize the odor contained in the air circulated inside the cooking chamber and dust The present invention relates to a microwave oven having an anion generator, which allows a user to cook in a sanitary cooking environment by sterilizing suspended bacteria.

In general, a microwave oven generates a high frequency of 2450 MHz by applying a high voltage to a magnetron, which is an ultra-high frequency oscillation tube.The microwave structure is changed as the microwave is applied to a dielectric food in a cooking chamber, and the food is cooked by the frictional heat generated therein. Device. Such a microwave oven is equipped with an electric heater inside the cooking chamber has been commercialized a multi-function microwave oven with the addition of the function of cooking using convective heat and radiant heat generated by the electric heater, such a typical example is shown in FIG.

As shown in FIG. 1, a conventional microwave oven includes a cooking chamber 20 having a tray for opening food and a food container, and a main body 10 having a door for opening and closing the cooking chamber 20. One side of an inner wall forming both inner sides of the cooking chamber 20 divides the electric chamber 30 and the cooking chamber 20. The electric field chamber 30 has a magnetron generating high frequency and spraying the cooking chamber 20, a high pressure transformer applying high voltage power to the magnetron, and a cooling fan 31 for cooling the magnetron and the high voltage transformer. It is installed at an appropriate position, the heater 22 which selectively generates heat on one side inner wall of the cooking chamber 20 is rotatably installed around one side, the heat generated when the heater 22 is driven cooking chamber 20 A convection pan 23 for circulating therein is installed at the rear of the cooking chamber 20.

In the conventional microwave oven having such a configuration, when the cooking is performed, the magnetron and the heater are selectively driven to heat food disposed in the cooking chamber to perform cooking. At this time, the cooling fan 31 is driven to operate the electric compartment 30 Air is blown out of the main body 10 via the heating chamber, and when the heater 22 is driven, the convection fan 23 is selectively driven to heat the heat generated by the heater 22. By evenly circulating in, the food was heated quickly and increased visual effects.

However, in the microwave oven performing the above function, the smell in the cooking chamber is discharged to the outside only by the operation of the cooling fan during the cooking or after the cooking is completed. Because it was difficult to achieve a practical effect, there was a problem that the effectiveness of sterilizing suspended bacteria or deodorizing airborne odors contained in air circulated inside the cooking chamber was greatly insufficient.

Accordingly, the present invention has been made to solve such a problem, an object of the present invention is to deodorize the airborne bacteria and deodorize the odor contained in the air circulated inside the cooking chamber at the start of cooking and after cooking is completed Therefore, to provide a microwave oven equipped with an anion generator that allows the user to cook in a hygienic cooking environment.

As shown, the present invention, the function selection unit 110 receives the type of cooking and cooking time desired by the user, the door opening and closing detection unit 130 for detecting the opening and closing of the diagram, and when cooking is started in the cooking chamber A cooking chamber temperature sensing unit 120 for sensing a temperature, a magnetron driver 140 for driving a magnetron, and a cooling fan 31 for cooling the magnetron and circulating air in a cooking chamber when the magnetron is driven, Cooling fan driver 150, a heater driver 170 for driving the heater 22 is installed on one side of the cooking chamber selectively driven, and selectively driven to circulate the heat generated during the heater driving in the cooking chamber The convection driving unit 160 for driving the convection fan 23 and the heater 22, the magnetron, the convection fan 23 and the image according to the type of cooking selected by the function selecting unit 110. Includes a control unit 100, and a negative ion generating means for deodorizing the odors and smoke generated while cooking to perform sterilization of floating bacteria 200 for controlling the driving of the cooling fan (31).

The negative ion generating means 200 is preferably installed in at least one of the inlet and exhaust ports through which air is introduced into and discharged from the cooking chamber by the driving of the cooling fan 31.

In the above configuration, as shown in FIG. 3, the negative ion generating unit 200 receives the high voltage from the high voltage generator 210 and the negative voltage of the negative voltage of −6 kV, for example, from the high voltage generator 210. Generated by the plate 220, the charge plate 230 receiving a positive voltage from the high voltage generator 210, for example, a voltage of OkV, and the corona discharge of the ion plate 220 and the charge plate 230.
