Description
Technical field
The present invention relates to the invention of the ground structure aspect of micro-wave oven.
Background technology
Fig. 1 expresses the stereogram of the heating clamber assembly of general micro-wave oven.As shown in the figure, be formed with heating clamber 12 on the heating clamber assembly 10 of micro-wave oven, heating clamber 12 is positioned at core, is used for heat food.Be formed with electric control chamber 14 on the adjacent part of heating clamber 12, electric control chamber 14 is provided with electronic unit, and electronic unit imposes on heating clamber 12 with microwave.Such as electric control chamber 14 is provided with and is used to produce microwave magnetron and high pressure is imposed on the high-tension transformer of magnetron and high-voltage capacitance etc.
Because electric control chamber 14 has multiple electronic unit, must utilize power-line ground end to carry out ground connection, ground terminal is connected on the part that does not have spraying, when on heating clamber assembly 10, carrying out ground connection, in the ordinary course of things, utilization is formed on the edge part 16 of rear wall, carries out the ground connection of heating clamber assembly 10.
As shown in Figure 1, the edge part 16 of heating clamber assembly 10 rear walls is the parts towards the horizontal direction bending from rear wall that have certain-length.On edge part 16, be fixed with the exterior case (not expressing in the drawing) of the U word shape of lower opening, form the outward appearance of micro-wave oven.
In addition, as shown in Figure 1, be formed with grounding parts 18 on the edge part 16 above heating clamber assembly 10 rear walls.Be formed with secure bond hole 18a on the grounding parts 18.Because the ring terminal and the secure bond screw fixings that are attached on the ground terminal end are combined on the 18a of secure bond hole, so the depression that grounding parts 18 forms towards the below.
Fig. 2 expresses the A expansion plane partly that Fig. 1 expresses.As shown in the figure, because rear wall 19 upper ends of grounding parts 18 and the state that edge part 16 is positioned at sustained height, under above-mentioned state, in order to form grounding parts 18, the finedraw (S) of formation incision between the upper end of rear wall 19 and grounding parts 18.That is to say,, between rear wall 19 and edge part 16, form finedraw (S) afterwards,, form the aforesaid grounding parts that is recessed to form towards the below 18 between rear wall 19 and the edge part 16 by towards the below pressurization in order to be recessed to form grounding parts 18 towards the below.
To process towards the part of below depression from the edge part 16 of heating clamber assembly 10 rear walls of prior art, can only form aforesaid finedraw (S).But because finedraw (S) is isolated grounding parts 18 and rear wall 19, so weakened the support strength of the grounding parts 18 of prior art structure.
That is to say that the grounding parts 18 from the edge part 16 of heating clamber assembly 10 rear walls is recessed to form towards the below separates by finedraw (S) and rear wall 19, so do not possess any supporting relation.So on intensity, the grounding parts 18 of prior art is very fragile, in the secure bond process of ground connection screw or apply other external force, grounding parts 18 will easily be out of shape.
Summary of the invention
Technical problem to be solved by this invention is, a kind of ground structure of micro-wave oven is provided, the grounding parts at heating clamber assembly rear wall edge part place makes the screw of ground connection possess sufficient support strength, the secure bond screw of support fixation power-line ground end more securely can sustain damage the grounded part of micro-wave oven or is out of shape owing to external force.
In order to solve the problems of the technologies described above, the technical solution used in the present invention is: the ground structure of micro-wave oven be included on the heating clamber assembly rear wall towards front horizontal curvature edge part, pressurize and make edge part be recessed to form grounding parts towards the below, and make the upper end of grounding parts and rear wall form horizontal plane, grounding parts is connected with rear wall and edge part.
The ground structure of described micro-wave oven is formed with the secure bond hole on grounding parts, secure bond hole secure bond is useful on the screw of ground connection
The invention has the beneficial effects as follows: the ground structure of micro-wave oven of the present invention, its grounding parts links on the rear wall 24 and edge part 20 that is supported on the heating clamber assembly simultaneously, the secure bond screw of support fixation power-line ground end more securely can sustain damage the grounded part of micro-wave oven or is out of shape owing to external force.

Main symbol among the figure:

The specific embodiment
Below in conjunction with the drawings and specific embodiments the present invention is described in further detail: Fig. 3 expresses the part stereogram of ground structure of the present invention, expresses the rear wall of the heating clamber assembly of micro-wave oven.
As shown in the figure, heating clamber assembly 24 rear walls above be formed with edge part 20.When the top of heating clamber assembly was coated with the exterior case of U font of lower opening, edge part 20 was close to exterior case, can prop up the casing of support integral micro-wave oven securely.
To be grounding parts 30 be recessed to form the secure bond screw of grounding parts 30 secure bond ground terminals from edge part 20 towards the below to the ground structure of micro-wave oven of the present invention.Be formed with secure bond hole 32 on grounding parts 30, secure bond hole 32 secure bond are used for the screw of ground connection.
By the ground structure of micro-wave oven of the present invention, can recognize that top, rear at the grounding parts 30 that is recessed to form does not have the rear wall 24 of heating clamber assembly.That is to say that in prior art, enlarged as shown in Figure 1 is extruded with the rear wall 19 of heating clamber assembly at the rear of grounding parts 18, be formed with finedraw (S) between the back 19 of the rear of grounding parts 18 and heating clamber assembly.
By the ground structure of micro-wave oven of the present invention, owing to there is not the rear wall 24 of heating clamber assembly on the rear of grounding parts 30, grounding parts 30 forms the state of being close to the rear wall 24 of heating clamber assembly.So, when the rear wall 24 of grounding parts 30 and heating clamber assembly links, also be attached at left and right sides with edge part 20, compare the prior art structure, have very strong support strength significantly.
In addition, in order to form grounding parts 30, the both sides of the grounding parts 30 of depression are formed with the inclined plane (Aa) of inclination.Wherein, inclined plane (Aa) and the horizontal plane that on grounding parts 30, joins part (Ab) with inclined plane (Aa) and with inclined plane (Aa) and horizontal plane partly (Ab) part of joining simultaneously compile by 3 planes and form, form the part of Different Plane by processing (such as, punch process).So, hole (Sb) processing is helped each face and keeps flat state as shown in the figure in above-mentioned part.By the ground structure of micro-wave oven of the present invention, the part compiled of the rear wall 24 of the heating clamber assembly that joins simultaneously to grounding parts 30 and inclined plane (Aa) and with grounding parts 30 and inclined plane (Aa) only, partly perforation (Sb).
Also link when linking, compare prior art and more possess support strength with edge part 20 for the rear wall 24 of grounding parts 30 and heating clamber assembly.So the secure bond power-line ground end period of the day from 11 p.m. to 1 a.m or because other outside external force can easily not produce distortion can provide the support that intensity is more arranged.
