Description
Technical field
The present invention relates to a kind of micro-wave oven, relate to a kind of outer set assembling structure (structure for assembling in microwave oven) that constitutes the micro-wave oven profile or rather.
Background technology
In general, micro-wave oven (MWO, microwave oven) is that (per second 2 450MHz) as heating source, utilizes the intermolecular frictional heat that produces by the molecules align that upsets food to come the machine of cooking food with high frequency waves.
Such micro-wave oven generally comprises with lower member and constitutes as shown in Figure 1, has formed the shell (out case) 10 of machine outward appearance that is:; Formed the base plate (base plate) 20 of bottom surface; Formed the cavity 30 of cooking room; Can make cavity 30 open or closed door parts 40.
Above-mentioned shell 10 can be surrounded above-mentioned cavity 30, thereby plays from the effect of the above-mentioned cavity 30 of outer protection.
And also have the front framework 50 and the rear frame 60 that are connected with above-mentioned shell 10, base plate 20 and door part 40 respectively on the above-mentioned cavity 30, they are assembled in the front and back of cavity 30 respectively.
Here, above-mentioned front framework 50 has not only formed the front of above-mentioned cavity 30, and simultaneously it also is connected on the above-mentioned door part 40 and the place ahead of base plate 20.And above-mentioned rear frame 60 has not only formed the back of above-mentioned cavity 30, and it also is connected to the rear of above-mentioned base plate 20 and the rear of shell 10 simultaneously.
Fig. 2 and Fig. 3 have shown the assembled state between each part of above-mentioned micro-wave oven, describe connection structure between each part in detail below with reference to Fig. 1, Fig. 2 and Fig. 3.
At first, be formed with the 1st screw connecting hole 21 respectively on two angles in the place ahead of above-mentioned base plate 20, and the front of base plate 20 also is formed with several card projections 22.Corresponding therewith, then be formed with respectively on two angles in the place ahead of front framework 50 and above-mentioned the 1st screw connecting hole 21 corresponding the 2nd screw connecting holes 51, and the front of front framework 50 also is formed with the hole clipping 52 that several can make above-mentioned each card projection 22 insert.
Therefore above-mentioned base plate 20 can be realized interconnecting with above-mentioned front framework 50 by connecting screw with the method that the card projection snaps in.
In addition, be formed with several the 3rd screw connecting holes 23 on the position, outer ring at the rear of above-mentioned base plate 20, then be formed with on the position, outer ring at the rear of back framework 60 respectively and above-mentioned the 3rd screw connecting hole 23 corresponding the 4th screw connecting holes 61.
