Abstract
The present invention discloses an assembly for a microwave oven controller. The assembly comprises a control panel, a supporting plate and an etched circuit board, wherein a supporting part formed by backwards extending is arranged on the back side of the control panel; a plurality of assembly parts which are formed by backward extended and are supported by the supporting part are arranged on the supporting plate; and the etched circuit board is fixed on the assembly parts of the supporting plate by a plurality of screws. Because the etched circuit board of the present invention is fixed on the supporting plate, at the time of the separation of the control panel, the etched circuit board can not be moved out along the control panel, and is combined in the supporting plate. Thus, a circuit wiring pattern of the etched circuit board can not direct contact the control panel, when users give oversized force on the front side of the control panel, the impact force can not be transferred to the etched circuit board, and the circuit wiring pattern, installed components, etc. arranged on the etched circuit board can be protected.
Description
Technical field
The present invention relates to a kind of micro-wave oven, particularly relate to a kind of controller of microwave oven assembly that the printed circuit board (PCB) that can control the micro-wave oven operation is installed.
Background technology
Fig. 1 is the microwave oven exploded perspective view of prior art.As shown in Figure 1, the inside of cavity 10 has the culinary art chamber 12 that can cook, and the one side is provided with electricity storage chamber 14.Shell 20 is centered around the outside of cavity 10 and forms end face and two sides of micro-wave oven.The front panel of cavity 10 fronts is provided with the door 22 that can open and close culinary art chamber 12 with rotating manner.Be arranged on front panel 30 1 sides and be provided with controller assemblies 34 with 14 corresponding opening portions 32 of electricity storage chamber.Fig. 2 is the controller of microwave oven modular construction exploded perspective view of prior art.As shown in Figure 2, control panel 40 is panels of regulating micro-wave oven, and forms the shell of controller assemblies 34, and its lateral surface is provided with display part through hole 42 and a plurality of button pass through hole 44 and is installed in peristome 32 fronts on the front panel 30.In addition, being provided with in the button pass through hole 44 can be to the outstanding button in control panel 40 fronts.Be provided with between display part through hole 42 and the button pass through hole 44 to be printed on and thaw and cooking function such as culinary art and set the keyboard 48 of various preference patterns such as above-mentioned cooking function start-up time.Fig. 3 is a control panel structure cutaway view in the controller of microwave oven assembly of prior art.As shown in Figure 3, the back side of control panel 40 forms a plurality of pillars 52 that rearward extend, and pillar 52 is provided with combined hole 54.The back side 50 of control panel 40 is provided with the support portion 56 that can support support plate 60 and the size rectangle support plate 60 less than control panel 40.As shown in Figure 2, also be provided with through hole 62,64 on the support plate 60 corresponding to display part through hole 42 on the control panel 40 and a plurality of button pass through hole 44, and a plurality of pillar holes 66 of the inserted pillar 52 that forms corresponding to pillar 52.The rear of support plate 60 is provided with printed circuit board (PCB) 70, is formed with the various wiring patterns that can be connected with a plurality of input units such as keyboards with the knob 46 that is arranged on control panel 40 fronts on this printed circuit board (PCB) 70.Printed circuit board (PCB) 70 is provided with corresponding with pillar 52 and can inserts a plurality of through holes 76 of pillar 52.Pass on the then outstanding pillar 52 of pillar hole 66 and through hole 76 printed circuit board (PCB) 70 has been installed, screw 78 then passes through hole 76 and printed circuit board (PCB) 70 is fixed on the control panel 40.But, there is following problem in the controller of microwave oven assembly of this prior art, promptly, for printed circuit board (PCB) 70 is installed on the control panel 40, need be provided with pillar 52 on the back side 50 of control panel 40, and need be respectively equipped with on printed circuit board (PCB) 70 and the support plate 60 and pillar 52 corresponding through hole 76 and pillar holes 66, at first with after 66 alignment of through hole 76 and pillar hole, and then in the combined hole 54 of pillar 52 fixing screwing 78.Because printed circuit board (PCB) 70 and 40 of control panels are directly fixing with screw 78, so if front panel 30 need be separated with control panel 40, the printed circuit board (PCB) 70 that so directly is fixed on the control panel 40 also needs to take out simultaneously.And the wiring pattern 72 on the printed circuit board (PCB) 70 is the direction settings towards control panel 40, and the surface at wiring pattern 72 places is directly supported by the pillar 52 of control panel 40, therefore, the end of pillar 52 might be damaged to wiring pattern 72, and the external impact that imposes on control panel 40 also may directly be passed to printed circuit board (PCB) 70 and make the wiring pattern 72 on it produce misoperations.
Summary of the invention
In order to address the above problem, the object of the present invention is to provide a kind of controller of microwave oven assembly that printed circuit board (PCB) directly is not fixed on the control panel.
In order to achieve the above object, controller of microwave oven assembly of the present invention comprises: the back side is provided with the control panel of the support portion that forms of extending back; By supporting and have a support plate of the outstanding a plurality of departments of assembly that form backward in the support portion; With the printed circuit board (PCB) in the department of assembly that is fixed on support plate by a plurality of screws.
The two side, support portion of described control panel is provided with a plurality of combined holes, and is formed with a plurality of thrusts on the two sides of support plate, thrust elasticity is combined in the combined hole support plate is fixed on the support portion.
Because controller of microwave oven assembly provided by the invention is that printed circuit board (PCB) is fixed on the gripper shoe; like this when control panel is separated; printed circuit board (PCB) can not shift out thereupon; but be combined on the gripper shoe; therefore the wiring pattern of printed circuit board (PCB) just can directly not contact with control panel; so if the user applies excessive power for the front of control panel; this impulsive force can not be sent on the printed circuit board (PCB) yet, thereby can protect wiring pattern on the printed circuit board (PCB) and element of installation etc.
