Above-mentioned chassis one side is formed with the breakthrough part corresponding with slot, and printed circuit board (PCB) is arranged at the back side on chassis, in order to fix this printed circuit board (PCB), the back side, chassis is provided with: it is dimetric to a pair of support convex on the angle point and a pair of support hook to be positioned at the right angle separately.In order to protect indicator lamp, the present invention also should include from the indicator-lamp cover of external lid indicator lamp.
According to the present invention of structure as mentioned above, indicator lamp is opened along with the operation of micro-wave oven, so the operation that the user can confirm micro-wave oven easily whether.
Below, the possible embodiment according to door for microwave oven of the present invention is described.
Fig. 2 is the front elevation that shows according to the outward appearance of the embodiment of door for microwave oven of the present invention, and Fig. 3 is the cross-sectional view that shows the major part among the embodiment shown in Fig. 2, and Fig. 4 is the back view of a part that shows the chassis of the embodiment shown in the pie graph 2.
As shown in the figure, in a side of micro-wave oven main body 11, be provided with door 13 rotationally; In addition, with respect to the position of above-mentioned door 13 1 sides, that is, the front of main body 11 possesses and has: receive the various operation signals relevant with the operation of micro-wave oven, and the various information in the running of microwave oven are shown to outside control part 19; Moreover the central portion of door 13 is provided with a glass 15.Here, the effect of this glass 15 is: the user can externally confirm the state of the food of cooking in culinary art chamber (not have among the figure point out).Also have, a side of door 13 possesses and has: the user is in order to open or close door 13, and the door handle 17 that grasps.
As shown in Figure 3, a side of door face board 21 that constitutes the front outward appearance of above-mentioned door 13 is formed with slot 21a, and this slot 21a is that the part with respect to the door face board 21 of door handle 17 opposition sides connects the back to the front and back of door 13 and forms.The effect of this slot 21a is: make the indicator lamp 28 with explanation below be exposed to the outside.
Above-mentioned door face board 21 inside possess chassis 23 are arranged, and this chassis 23 is the positions that are used to be provided with the printed circuit board (PCB) 27 that will illustrate below; Chassis 23 1 sides are formed with the corresponding breakthrough part 23a with slot 21a; In addition, chassis 23 is fixed between door face board 21 and the door frame (not prompting among the figure).Here, door frame is fixed in the back side of door face board 21.23 back sides, chassis are provided with printed circuit board (PCB) 27, and for fixed printed circuit board 27,23 back sides, chassis possess a pair of support convex 24 and support hook 25 are arranged, and support convex 24 is close to front one side of printed circuit board (PCB) 27.In this state, support hook 25 will be close to the back side one side of printed circuit board (PCB) 27, therefore this printed circuit board (PCB) 27 can be fixed in the back side on chassis 23.
Above-mentioned support convex 24 and support hook 25 are positioned at printed circuit board (PCB) 27 corresponding straight dimetric on the angle point separately.That is, be not provided with printed circuit board (PCB) 27 chassis 23 a back side part as shown in Figure 4, this support convex 24 is arranged at the back side on the corresponding chassis 23 in upper end, right side that dot and printed circuit board (PCB) 27 and lower end, left side.In addition, support hook 25 is arranged at the back side with the above-mentioned chassis 23 of upper end, the left side of printed circuit board (PCB) 27 and lower end, right side separately.
In addition, possess in the above-mentioned printed circuit board (PCB) 27 various electric elements are arranged, therefore the front of this printed circuit board (PCB) 27 possesses at least an indicator lamp 28 is arranged, and this indicator lamp 28 will be opened along with the operation of micro-wave oven, can make operation that the user externally confirms micro-wave oven easily whether; Indicator lamp 28 will be exposed to the outside by breakthrough part 23a and slot 21a.
In addition, in order to protect indicator lamp 28, be provided with indicator-lamp cover 29, at least a portion of this indicator-lamp cover 29 is made by transparent or semitransparent material, and comprises that following components constitutes: the protuberance 29a that protrudes into door face board 21 outsides by slot 21a; In the rear end of this protuberance 29a, be provided with the flange part 29b that forms with the radioactive ray form.Protuberance 29a forms corresponding to the shape of slot 21a and size, and under the state that protrudes to the outside, constitutes same plane with door face board 21.Flange part 29b forms relative size greater than slot 21a, and is fixed between door face board 21 and the chassis 23, therefore can prevent that indicator-lamp cover 29 is shed to the outside fully by slot 21a.
Below, the effect according to the embodiment of door for microwave oven of the present invention of structure is as mentioned above described.
At first, for cooking food, the door handle 17 that grasps door 13 is opened door 13, open culinary art chamber.The food that will need then to cook is closed door 13 after being positioned over the culinary art chamber interior, to close the culinary art chamber.Then, by operation control part 19, operation micro-wave oven, thereby cooking food.
In case micro-wave oven moves as mentioned above, possess in the indicator lamp 28 of a side of door 13 and will be lighted.Therefore, even be positioned on the relative position far away with micro-wave oven the user, or under the very big situation of the noise of user and micro-wave oven periphery, the operation that the user also can confirm micro-wave oven easily whether.
In addition, after the operation of micro-wave oven is finished, that is, after food cooking was finished, this indicator lamp 28 will extinguish.Therefore, the user can know that the culinary art work of micro-wave oven finishes, thereby can take out the food of finishing culinary art rapidly from the culinary art chamber.
According to aforesaid basic fundamental thought of the present invention be: the side at door for microwave oven is provided with the indicator lamp of lighting along with the various operations of micro-wave oven.
Beneficial effect of the present invention: as mentioned above, in the present invention, door for microwave oven is provided with the indicator lamp of lighting along with the various operations of micro-wave oven, so the operation that the user can externally confirm micro-wave oven easily whether.
Right of the present invention is not confined to aforesaid embodiment, but is decided by the record in claims.Under the situation that does not exceed the technology of the present invention scope of putting down in writing in claims, the operator of relevant industries can carry out various deformation and modification to it.
The above, it only is preferred embodiment of the present invention, be not that the present invention is done any pro forma restriction, every foundation technical spirit of the present invention all still belongs in the scope of technical solution of the present invention any simple modification, equivalent variations and modification that above embodiment did.
