Background
At present, the control panels of a plurality of household appliances can be turned upwards when being opened, and the control panels can be conveniently operated by a user after being turned upwards. As disclosed in chinese patent application No. 201610049973.3 (application publication No. CN 105555083 a) filed before the present inventor, a driving motor of the extending and resetting mechanism of the control panel of the household electrical appliance is mounted on a push rod, and when the driving motor works, the push rod can move along the fixing bracket through the cooperation of a meshing tooth part on the fixing bracket and a transmission gear on the push rod, so as to drive the control panel assembly to extend and reset. Although the mechanism structure works stably and reliably, particularly after the meshing tooth part of the fixed support is designed into a horizontal straight line segment and an arc segment structure, the control panel assembly can form a backward upward turning angle after extending forwards to the limit position, and the display state of the control panel is convenient for a user to watch. However, due to the adoption of the motor driving and transmission mechanism, the structure is relatively complex, the cost is relatively high, the problem of resetting during power failure is also required to be considered, and the control panel of the extending and resetting mechanism can only be in an upturned state when extending, so that the control panel can not be restored to a vertical position from an upturned position when extending.
In addition, some existing steam boxes on the market can realize the function of pushing out and overturning the control panel, and the main purpose of the steam box is to facilitate the steam box arranged on the water box to grab the water box, but the oven capable of realizing the overturning of the control panel is still little or none. The intelligent kitchen electric products have become a trend, the control panel of the steaming and baking micro products is provided with an interactive interface with higher performance, and on some high-end kitchen products, intelligent menus on the internet, songs, videos and the like can be checked on the control interface in a networking mode. Therefore, how to make the user use the control panel comfortably becomes a matter that the designer has to consider. Because the oven is generally located at the lowest end of the cabinet, and the control panel thereof is vertically fixed on the oven, when a user needs to operate the control interface, he needs to squat down to operate, which seriously affects the user experience.

As shown in fig. 5, the control panel body 1 continues to turn upwards, because the limiting rod 71 is already propped against the lower end of the arc-shaped limiting groove 91 at this time, the limiting rod 71 starts to drive the movable turntable 9 to rotate anticlockwise synchronously, and the movable turntable 9 further pushes the pawl 8 downwards to separate the pawl 8 from the ratchet 7, at this time, the turning angle of the control panel body 1 is larger than the lockable maximum turning angle. As shown in fig. 6, the control panel body 1 starts to turn down in the state shown in fig. 5, the ratchet 7 rotates clockwise along with the control panel body, so that the stop lever 71 is driven to move against the upper end of the arc-shaped stop groove 91, in the process, the movable turntable 9 still acts on the pawl 8 to keep the pawl 8 separated from the ratchet 7, then, the control panel body 1 continues to turn down, the ratchet 7 drives the movable turntable 9 to rotate clockwise, as the movable turntable 9 rotates clockwise, the acting force of the movable turntable 9 on the pawl 8 disappears, the pawl 8 is restored to be engaged with the ratchet 7 under the action of the torsion spring, and the control panel body 1 is restored to the vertical position.
The movement mechanism in the embodiment can be suitable for various household appliances with control panels, such as ovens, steam boxes, steaming and baking integrated machines and the like.
