A wall-mounted microwave oven including a cooking chamber, a heater casing, a heater installed in the heater case, a blowing fan to supply hot air generated in accordance with a heating operation of the heater, first guide members to guide the hot air, supplied by the blowing fan, to be introduced into the cooking chamber, and second guide members to guide the hot air to circulate along the heater. The first and second guide members allow hot air to be rapidly introduced into the cooking chamber while being rapidly heated to a desired high temperature. Also, the hot air can effectively circulate in the cooking chamber. Accordingly, it is possible to reduce a cooking time and enhance cooking efficiency.

Wall-mounted microwave oven

A method and apparatus for controlling the operation of a microwave oven, including a magnetron generating microwaves and a sensor sensing the state of air in the cooking cavity of the oven. The cooking period is determined by searching one of two data tables in accordance with a determination result after determining whether food to be cooked is included in ascending slope-type foods or descending slope-type foods. The control method and apparatus remarkably reduces a deviation in the cooking periods by distinguishing the ascending slope-type foods from the descending slope-type foods. The control method and apparatus allows the microwave oven to appropriately cook food for a period of time which substantially matches a practically required cooking period, thus providing a good cooking result.

Method and apparatus for controlling microwave oven

A microwave oven, capable of cooking food by steam generated through a microwave heating operation. The microwave oven includes a cabinet provided with a cooking cavity and a microwave irradiating unit irradiating microwaves into the cooking cavity. The microwave oven includes a steaming unit. The steaming unit includes a steaming container and a cover. The steaming container is made of a microwave penetrable material and is installed to an upper portion of the cabinet such that a lower portion of the steaming container is placed in the cooking cavity. The steaming container is open at a top thereof and the cover selectively closes the open top of the steaming container.

Microwave oven to cook food with steam generated through a microwave heating operation

A polymer-type humidity sensor for use in a microwave oven and which has a polymer structure which includes a rubber and a predetermined amount of carbon, and a pair of electric terminals connected to the polymer structure. The polymer-type humidity sensor of the present invention has a rapid response time, durability, excellent adherence to terminals, low hysteresis, and exhibits stability to exposures of high temperatures and high relative humidity.

Polymer-type humidity sensor

A microwave oven includes a humidity sensor, a main-outlet and a sub-outlet formed at opposite sidewalls of a cooking cavity such that the cooking cavity communicates with the atmosphere through the main-outlet and the sub-outlet. The sub-outlet is installed in a machine room adjacent an air inlet side of a cooling fan. The humidity sensor is installed in the machine room at a position adjacent to the sub-outlet and senses the humidity of air inside the cooking cavity by sensing the humidity of a part of the air discharged from the cooking cavity through the sub-outlet. The surface of the humidity sensor is less likely to be easily contaminated by the air exhausted from the cooking cavity, moisture deposited on the surface of the humidity sensor is quickly evaporated so that the humidity sensor performs its desired operation even when the microwave oven sequentially performs several cooking processes.

Microwave oven with humidity sensor

A microwave oven performs a cooking operation in one of several cooking modes having a first cooking time period and a second cooking time period. The first cooking time period is determined in accordance with an output value of a sensor which senses a state of air in a cooking cavity of the microwave oven. The second cooking time period is determined in accordance with the first cooking time period such that the first and second cooking time periods are expressed by a functional relation. The cooking modes include a standard mode with a standard second cooking time period, a high mode with a longer cooking time than the standard second cooking time period, and a low mode with a shorter cooking time than the standard second cooking time period. The high mode is preset such that a variation in its second cooking time period is increased in proportion to the first cooking time period, while the low mode is preset such that a variation in its second cooking time period is increased in inverse proportion to the first cooking time period. The microwave oven allows a user to set a cooking time period such that the cooking time period is controllably lengthened or shortened in proportion to the quantity of food contained in the microwave oven.

Microwave oven

A microwave oven, and method of controlling the same, including a magnetron generating high-frequency waves and a sensor detecting the environmental state of air in a cooking cavity. During a first cooking time, outputs of the sensor are sampled at predetermined periods, with the duration of first cooking period being calculated, by a controller, based on the result of the sampling. Thereafter, a second cooking time is calculated, by the controller, based on the first cooking time and the kind of food. A cooking operation is then completed for the second cooking time.
