Abstract
A microwave oven having a body casing forming a cooking chamber, an outer casing enclosing the body casing, and a magnetron for supplying the cooking chamber with microwaves is provided. The microwave oven includes a plurality of high-voltage transformers installed in series between the top of the body casing and the outer casing, each high-voltage transformer supplying the high voltage to the magnetron. With this configuration, the height for installing the high-voltage transformer is lowered, so the cooking chamber can be extended to a rear area of the control panel to thereby increase the size of the cooking chamber. The heat generated from the component chamber can be effectively discharged outside, and turns of a winding for the high-voltage transformer can be decreased, thereby reducing the cost of production.
Claims20
A microwave oven, comprising:
- a body having an interior cooking chamber and a top plate forming a ceiling of said cooking chamber, having a first side plate and a second side plate both joined by said top plate and forming opposite sides of said cooking chamber;
- an outer casing spaced apart from said top plate and said first and second side plates of said body, said outer casing enclosing said body, said outer casing defining a top space formed between said outer casing and said top plate of said body, a first side space formed between said outer casing and said first side plate of said body, and a second side space formed between said outer casing and said second side plate of said body;
- a magnetron supplying said cooking chamber with microwave energy, disposed within said second space;
- and
- a plurality of high-voltage transformers installed in said top space, said high-voltage transformers being coupled to said magnetron to supply a driving voltage, said high-voltage transformers connected in series and being connectable between two terminals of an external power source.
A microwave oven, comprising:
- a body having a cooking chamber, having a top plate forming a ceiling of said cooking chamber, and having a first plate and a second side plate joined to said first side plate by said top plate;
- an outer casing spaced apart from said top plate and said first and second side plates, enclosing said body casing, defining a top space formed between said outer casing and said top plate, a first side space formed between said outer casing and said first side plate, and a second side space formed between said outer casing and second side plate,
- an inlet installed on a front and side portion of said oven between said first side plate and said outer casing to communicate with said first side space providing an air passage for outside air to be drawn into said first side space, said top space, and said second side space in sequence;
- a first aperture formed on said second side plate to allow the air drawn into said second side space to flow into said cooking chamber;
- a second aperture formed on said top plate to allow the air drawn into said cooking chamber to flow into said top space;
- a plurality of high-voltage transformers mounted on said top plate of said body within said top space;
- and
- an outlet installed across a front and top portion of said oven between said top plate and said outer casing and connected to said second aperture of said top plate outside of said microwave oven, wherein the air drawn from said inlet is blown into said cooking chamber through said first side plate, said top space, and said second side space, and discharged from the cooking chamber through said outlet.
A microwave oven, comprising:
- a body casing having a cooking chamber, having a top plate forming a ceiling of said cooking chamber, and having a first side plate and a second side plate both forming sides of said cooking chamber;
- an outer casing enclosing said body casing and spaced-apart from said top, first side, and second side plates of said body, said outer casing defining a top space, a first side space, and a second side space with said top plate and first and second side plates, respectively;
- at least two high-voltage transformers disposed in said top space said transformers each including a primary winding having a first terminal and a second terminal, each first terminal of said primary windings being connectable to an external power source, each second terminal of said primary windings coupled to each other, said transformer each including a secondary winding having a third terminal and a fourth terminal, each third terminal coupled to a magnetron while each fourth terminal is coupled to each other without coupling to a ground terminal;
- and
- an inlet disposed between said first side plate and said outer casing to allow external air to be drawn into said first side space and to be blown into said cooking chamber through said top space and said second side space in sequence.
