Description
Technical Field
The utility model relates to a kitchen household appliance, in particular to a microwave oven.
Background
In a microwave oven, a filter circuit board belongs to a strong electric component, a fault is easy to cause a fire, the filter circuit board is required to be grounded according to the installation standard, the filter circuit board is fixedly connected to a plastic installation frame, and a lead is led out of the filter circuit board and is fixed to other metal pieces of a product. This kind of mounting means is complicated relatively, and the dismouting is troublesome moreover, extravagant manpower and materials, and the cost is also higher.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem that a microwave oven is provided, its technical scheme who adopts is: a microwave oven, includes casing, filter circuit board, its characterized in that: the filter circuit board comprises a filter circuit board metal mounting support and is characterized by further comprising a filter circuit board metal mounting support, wherein the filter circuit board metal mounting support is fixedly connected with the shell, a copper foil exposed portion is arranged on the filter circuit board and provided with a grounding mounting hole, a protruding portion matched with the exposed portion on the filter circuit board is arranged on the filter circuit board metal mounting support, the protruding portion is also provided with a grounding mounting hole, and the grounding mounting hole of the copper foil exposed portion on the filter circuit board and the grounding mounting hole of the protruding portion on the filter circuit board metal mounting support are connected through a grounding screw.
The utility model discloses further technical characteristic is:
and the filter circuit board and the metal mounting bracket of the filter circuit board are correspondingly provided with fixed mounting holes, and the fixed mounting holes of the filter circuit board and the metal mounting bracket of the filter circuit board are connected through fixing screws.
The utility model has the advantages that:
because filter circuit board is provided with the metal installing support, filter circuit board metal installing support and casing fixed connection, and be provided with the copper foil exposed portion on the filter circuit board, the copper foil exposed portion is provided with the ground connection mounting hole to be provided with on the filter circuit board metal installing support with the protruding portion that the exposed portion matches on the filter circuit board, the protruding portion is provided with the ground connection mounting hole equally, the ground connection mounting hole of the last protruding portion of copper foil exposed portion of filter circuit board and the ground connection mounting hole of the last protruding portion of filter circuit board metal installing support are connected through the ground connection screw. Therefore, the filter circuit board is grounded without leading out a lead to be connected to other metal parts, the grounding installation mode is simple, and the lead cost and the installation labor cost are saved.
Drawings
Fig. 1 is a schematic structural diagram of an embodiment of the present invention.
Fig. 2 is an enlarged view of the structure of the connection surface between the metal mounting bracket of the filter circuit board and the filter circuit board in the embodiment shown in fig. 1.
Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and embodiments of the present invention.
Referring to fig. 1 and 2, a microwave oven includes a housing 1, a filter circuit board 2, and a filter circuit board metal mounting bracket 3, wherein the filter circuit board metal mounting bracket 3 is fixedly connected to the housing 1, a copper foil exposed portion 201 is provided on the filter circuit board 2, the copper foil exposed portion 201 is provided with a ground mounting hole 4, a protruding portion 301 matched with the exposed portion 201 on the filter circuit board is provided on the filter circuit board metal mounting bracket 3, the protruding portion 301 is also provided with the ground mounting hole 4, and the ground mounting hole 4 of the copper foil exposed portion 201 on the filter circuit board is connected to the ground mounting hole 4 of the protruding portion 301 on the metal mounting bracket by a ground screw (not shown).
In this embodiment, the filter circuit board 2 and the metal mounting bracket 3 are correspondingly provided with fixing mounting holes 5, and the fixing mounting holes of the filter circuit board and the metal mounting bracket are connected through fixing screws (not shown). So that the connection between the filter circuit board 2 and the metal mounting bracket 3 is more secure.
Because filter circuit board is provided with the metal installing support, filter circuit board metal installing support and casing fixed connection, and be provided with the copper foil exposed portion on the filter circuit board, the copper foil exposed portion is provided with the ground connection mounting hole to be provided with on the filter circuit board metal installing support with the protruding portion that the exposed portion matches on the filter circuit board, the protruding portion is provided with the ground connection mounting hole equally, the ground connection mounting hole of the last protruding portion of copper foil exposed portion of filter circuit board and the ground connection mounting hole of the last protruding portion of filter circuit board metal installing support are connected through the ground connection screw. Therefore, the filter circuit board is grounded without leading out a lead to be connected to other metal parts, the grounding installation mode is simple, and the lead cost and the installation labor cost are saved.
It will be appreciated by persons skilled in the art that the above embodiments are illustrative and not restrictive. Different features which are present in different embodiments may be combined to advantage. Other variations to the disclosed embodiments can be understood and effected by those skilled in the art upon studying the drawings, the specification, and the claims.
