Cooking room 2 is communicated with the outside selectivity of micro-wave oven by the switching of door 6.Door 6 front one side is provided with handle 6 ', the inner face of door 6 protrude be provided with respect to the door bolt 7,7 ' of door bolt slit 5,5 '.
In having the micro-wave oven of the as above prior art of structure, keeper plate 20 is located at micro-wave oven front panel 4 back, the mounting groove 10a that forms on the installing plate 10 of front panel 4 and be formed on keeper plate 20 and groove 22a on the axle sleeves 22 is installed fixes with fixed screw after buckling is installed on the front panel 4.
But prior art is fixed front panel and keeper plate 20 by the fixing of screw, needs other fixed screw, and, fixing after the mounting groove aligning, so the operation more complicated.
Summary of the invention
Technical problem to be solved by this invention provides a kind of other installing component that do not need, and simply keeper plate is combined in micro-wave oven keeper board mounting assembly on the front panel.
In order to solve the problems of the technologies described above, the technical solution used in the present invention is: a kind of keeper plate erecting device of micro-wave oven, comprise from the installing plate of the central portion electric component chamber side end curved elongated formation rearward that constitutes the micro-wave oven casing front panel, form the protrusion sheet that hanging groove and cooking room side distortion are in the past protruded on the installing plate; Be arranged on front panel central portion rear, have the hook that protrudes to the installing plate side and the keeper plate of the support bar that protrudes with the same direction of hook, the hook of keeper plate hangs on the hanging groove, and support bar is protruded sheet is pressing, and keeper plate is installed on the installing plate.
The end of described hook is crooked downwards; Protruding sheet is that cut position sidepiece of installing plate and lower end, and the upper end is crooked toward the inboard structure of protruding.
The upper end of described protrusion sheet central authorities form porose, protrude bending tablet 5 degree～10 degree for well.
Described hanging groove is to form two hanging grooves up and down, is formed with on the certain position between the hanging groove to protrude sheet for well.
Keeper plate of the present invention is to hang in the hanging groove of installing plate of front panel, and with supported underneath, and the support bar of keeper plate is supported toward the top by the pressing part of front panel installing plate.Do not need installing component to carry out the installation of keeper plate and front panel, reduced the quantity of parts, simplify manufacturing process, reduced the manufacturing unit price of micro-wave oven, improved productivity.

The specific embodiment
Be described in further detail below in conjunction with the keeper plate erecting device of the drawings and specific embodiments micro-wave oven of the present invention:
As shown in Figure 3, the direction of the arrow among the figure is the place ahead of expression micro-wave oven, and the rear that constitutes the front panel 104 of micro-wave oven outward appearance is provided with keeper plate 120.Possess in the front panel 104 at the central portion electric component chamber side end installing plate 110 of curved elongated rearward, perforation is formed with most hanging grooves 113 on the installing plate 110.Do not form to be provided with on the part of hanging groove 113 front panels 104 and have elasticity and protrude the protrusion sheet 115 that forms toward inboard certain angle.The top and the bottom of installing plate 110 form a pair of hanging groove 113 in the present embodiment, form between two hanging grooves to protrude sheet 115.
Protruding sheet 115 is that the sidepiece of the part of installing plate 110 and lower end are cut, and the upper end bending is protruded and formed.And, protrude the soft bending of sheet 115 energy or stretching in order to make, on 115, to decide interval incision or form hole 115a for one, present embodiment is hole 115a.Protrude the sheet 115 crooked angles of protruding and keep 5 degree～10 degree, when the hook 122 of the keeper plate 120 that will illustrate below hangs over the hanging groove 113 of installing plate 110, can softly launch.
Be formed with the hook 122 that can hang in the hanging groove 113 on the keeper plate 120 of installing on the plate 104 in front.Link up with till the length that hanging groove 113 that 122 length extend to installing plate 110 can insert, the end is bent to form downwards by certain-length.
On the keeper plate 120 corresponding to the top formation of the position of front panel 104 with protrude the support bar 124 that sheet 115 contacts.Support bar 124 is to form with thin plate-like shape, has certain intensity, supports keeper plate 120.
Shown in Fig. 4,5,6, the process that keeper plate 120 is installed on the front panel 104 is:
Insert the hook 122 of keeper plate 120 at first, in front on the hanging groove 113 that forms on the installing plate 110 of plate 104.Hook 122 inserts after the hanging grooves 113, and when mobile downwards, keeper plate 120 hangs on the installing plate 110 keeper plate 120.At this moment, press the protrusion sheet 115 of installing plate 110 downwards when moving toward the outside along with support bar 124, protrude sheet 115 and be with the upper end center outward elasticity rotate and make it not outstanding.So keeper plate 120 can hang on the installing plate 110.Protrude hole 115a that the upper end of sheet 115 forms and play to dwindle and protrude sheet 115 and the interval that installing plate 110 is connected, make the protrusion sheet 115 can more soft bending or stretching.When keeper plate 120 hangs over installing plate 110 fully, by the protrusion sheet 115 of the being pressed attitude that restores to the original state once more.Protrude sheet 115 restore to the original state once more toward inboard protrude to contact with support bar 124 top keeper plate 120 is not allowed up rock.
Secondly, keeper plate 120 hangs on the hanging groove 113 fixingly by linking up with 122 downwards, is upwards protruded sheets 115 by support bar 124 and supports, and is being fixed on the installing plate 110 under the state that does not rock.
The present invention discussed above forms hook and support bar on keeper plate, form hanging groove and pressing part on the installing plate of front panel, keeper plate and front panel is installed as technical thought under the situation that does not need other parts.In this thought category, the same industry has that the people of common knowledge can be out of shape with several different methods.
