Assembly structure of microwave oven

Abstract

The invention relates to a package assembly for a microwave oven which can simplify body connection construction integrally and cut down the number of union screws to minimum. The package assembly comprises: a cavity to form a cooking chamber; a fore frame in front of the cavity, a plurality of first open pores being formed on bottom surface of the fore frame; an after frame behind the cavity, a plurality of second connecting protuberances being formed at position near to bottom of the after frame; a base plate which forms a microwave oven base surface, a plurality of upward protruding first connecting protuberances being formed at fore end thereof, these first connecting protuberances being correspondingly connected to each of the first open pores of said cavity, and a plurality of second open pores formed at rear end of the base plate being correspondingly connected to each of the second connecting protuberances of said cavity; and a casing capable of enclosing said cavity.

Description

technical field [0001] The present invention relates to a microwave oven, more specifically to an external assembly structure (structure for assembling in microwave oven) constituting the outer shape of the microwave oven. Background technique [0002] Generally speaking, a microwave oven (MWO, microwave oven) is a machine that uses high-frequency waves (2,450MHz per second) as a heating source and uses intermolecular frictional heat generated by disturbing the molecular arrangement of food to cook food. [0003] such a microwave figure 1 As shown, it generally includes the following parts and constitutes, that is: an outer case (out case) 10 that forms the appearance of the machine; a base plate (base plate) 20 that forms the bottom surface; a cavity 30 that forms the cooking chamber; the cavity 30 can be opened. Or closed door part 40 . [0004] The housing 10 can surround the cavity 30 to protect the cavity 30 from the outside. [0005] Moreover, the cavity 30 also has...

Problems solved by technology

[0014] As mentioned above, the assembly structure of the existing microwave oven is generally connected by a lot of screws, so its operation process will inevitably be very complicated, which will bring about the problems of increased overall cost and increased manufacturing cost.

[0015] Not only that, during the use of the microwave oven, there will be a problem that the screws will be lost due to falling off and other reasons, which will make the overall connection state unstable, so there will be problems caused by the drive of the motor (omitted in the figure) and other reasons. problems causing vibration

[0016] In particular, the assembly structure of the existing microwave oven does not take into account the displacement in the up-down direction and the displacement in the front-rear direction between the various components, and is connected and fixed with multiple screws, so there will inevitably be an overall assembly efficiency low problem
