Embodiment Construction

[0030] Embodiments of the microwave oven of the present invention will be described in detail below with reference to the accompanying drawings.

[0031] Such as 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 sides of the housing 100 of the microwave oven. The inner panel 130 has a front opening as a whole. shape, including the back and two sides.

[0032] In addition, a front panel 140 and a rear panel 150 are coupled to front and rear ends of the housing 100, respectively. The front panel 140 and the back panel 150 actually form the front and rear appearance of the microwave oven. The front panel 140 and the back panel 150 have a rectangular plate-like structure extending to the top surface of the top panel 110 , the bottom surface of the bottom panel 120 and the side of the inner panel 130 respectively.

[0033] In addition, the front a...

Abstract

The invention discloses a microwave oven, which comprises a fan, at least one heater, a reflector and a heater cover, wherein the fan is arranged in a shell and generates airflow; the at least one heater is obliquely arranged in the shell relative to the direction of the airflow generated by the fan and is cooled by the fan; the reflector is used for reflecting heat generated by the heater and isprovided with a plurality of cooling holes in which the airflow generated by the fan flows; and the heater cover shields the heater and the reflector and has a passage in which the airflow generated by the fan is circulated, wherein the cooling holes positioned at the outlet side of the passage are smaller than the cooling holes at the inlet side. The microwave oven can cool parts composing of themicrowave oven, particularly distribution parts generating microwave and the heater generating electric heat more effectively so as to prevent the parts in an overheated state and improve the reliability of microwave oven operations.

Description

technical field [0001] The present invention relates to a microwave oven, in particular to a microwave oven capable of cooling components in the microwave oven more smoothly. Background technique [0002] Generally, a microwave oven is a cooking device that utilizes 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 conventional microwave oven cannot effectively cool the electronic components and / or the heater, thereby reducing the efficiency and operation reliability of the microwave oven. Contents of the invention [0004] The present invention is proposed to solve the problems in the prior art, and its purpose is to provide a microwave oven capable of cooling components more effectively. ...
