Embodiment Construction

[0031] Hereinafter, referring to the accompanying drawings, embodiments of the microwave oven of the present invention will be described in detail.

[0032] like Figure 1 to Figure 7 As shown, a top panel 110, a bottom panel 120 and an inner panel 130 are respectively provided on the upper and lower surfaces, the bottom surface and the two side surfaces of the housing 100 of the microwave oven. The inner panel 130 as a whole has an open front shape, including the back part and the two side parts.

[0033] In addition, a front panel 140 and a rear panel 150 are coupled to the front and rear ends of the casing 100, respectively. The front panel 140 and the back panel 150 actually form the front and back appearance of the microwave oven. The front panel 140 and the rear panel 150 have rectangular plate-like structures extending toward the top surface of the top panel 110 , the bottom surface of the bottom panel 120 , and the side surfaces of the inner panel 130 , respectivel...

Abstract

The invention discloses a microwave oven, which comprises a fan casing and a blade, wherein the fan casing is provided with at least one air-suction part and at least two air-discharge parts; the blade is rotatably arranged inside the fan casing, sucks in air through the air-suction part and discharges the air through the air-discharge parts; and by taking the rotation direction of the blade as astandard, the shortest distances D1 and D3 from the inner circumference surface of the fan casing to the outer circumference surface on the end of the inlet side of each air-discharge part is greaterthan the shortest distances D2 and D4 from the inner circumference surface of the fan casing to the outer circumference surface on the end of the outlet side of each air-discharge part. The microwaveoven can more effectively cool components forming the microwave oven, particularly a power distribution component producing microwave and a heater producing electric heat, through a first fan component and a second fan component, so the microwave oven can prevent the components from being in an overheating state and improve the action reliability of the microwave oven.

Description

technical field [0001] The present invention relates to microwave ovens, and more particularly, to a microwave oven capable of cooling parts more smoothly. Background technique [0002] Generally, a microwave oven is a cooking device that uses microwaves or / and electric heat to cook food. Such microwave ovens typically have electronic components that generate microwaves and / or heaters that generate electrical heat. In addition, a cooling system for cooling electronic components and / or heaters is provided in the microwave oven. [0003] However, the cooling system of the existing microwave oven cannot effectively cool the electronic components or / and the heater, thereby reducing the efficiency and reliability of the operation of the microwave oven. SUMMARY OF THE INVENTION [0004] The present invention is proposed to solve the problems in the prior art, and its object is to provide a microwave oven capable of cooling components more efficiently. [0005] In order to ach...
