Problems solved by technology

Therefore, even when the cooking time is short and there is no problem that the temperature of the reflecting plate rises due to the waste heat of the heater during cooking, the microwave oven still drives the cooling fan unnecessarily, resulting in a problem that the product cannot be effectively used.

Embodiment Construction

[0023] Hereinafter, the microwave oven according to the present invention will be described in detail with reference to the accompanying drawings.

[0024] figure 2 It is a control structure diagram for controlling the cooling fan in the microwave oven according to the present invention. Reference to the structure of the microwave oven in the present invention figure 1 be explained.

[0025] One side of the body 3 of the multifunctional microwave oven is provided with a magnetron (not shown in the figure), and a heater 5 is provided above the cooking chamber 1 . figure 1 Shown is exactly the structure that heater 5 is arranged on the top. Furthermore, a reflection plate 9 is installed on the above-mentioned heater 5 .

[0026] Since the temperature of the heater reflection plate 9 rises due to residual heat of the heater after the cooking with the heater 5 is completed, the cooling fan 7 is provided to solve this problem. Air is blown by the action of above-mentioned coo...

Abstract

The present invention relates to cooling fan controlling method and device for microwave oven, and is especially cooling fan controlling method and device for microwave oven of determining the cooling terminal time with thermistor and according to the temperature in the cooking chamber. After finishing cooking, cooling fan is so controlled that it cools only in case of cooking chamber temperature over specified value. The temperature is detected with the thermistor, and the present invention can save power and reach optimal cooling effect.

Description

technical field [0001] The present invention relates to a cooling fan control method and device for a microwave oven (Device and control method for cooling fan for microwave oven), more specifically, relates to a microwave oven that uses a thermistor to determine the cooling end time according to the temperature in the cooking chamber. Cooling fan control method and device. Background technique [0002] A magnetron is used as a heating source for a microwave oven to generate microwaves. If the above-mentioned microwaves are applied to food, the molecules in the food will rotate or vibrate at the same speed as their vibration frequency. When this vibration or rotation occurs, the frictional heat generated between the molecules causes the temperature of the food to rise rapidly to heat the food. [0003] In addition to the above-mentioned magnetron as a heat source, a heater has recently been added to a microwave oven as a heat source. Such heaters generally use halogen hea...
