Microwave oven turntable lift rotating equipment
Technical field
The utility model is a kind of lift rotating equipment, particularly a kind of microwave oven turntable rotating lifting gear.
Background technology
Chinese patent ZL02124224.0 has disclosed and a kind ofly can make the uniform microwave oven turntable lift rotating equipment of heating food more, this device comprises the rotary tray motor that driving force is provided, drive and be arranged on rotating ring components on the cavity bottom surface that inside has cooking room by rotary tray motor, be located at the inner rotating disk that also can rotate and can place food of cooking room with the rotation of rotating ring components, the lifter cam that when rotating disk rotates, rotating disk is pumped, described lifter cam be in the bottom surface of rotating disk along the roller of rotating ring components end below rotating disk rolling track and form, the roller of rotating ring components end and the contact-making surface of lifter cam are the sine surfaces of sinusoidal shape, said apparatus can make rotating disk can pump in rotation, the heat of microwave or heater generation just can be absorbed uniformly by food like this, thereby can make the gratin that is positioned on the rotating disk obtain uniform heating more.But the defective that said apparatus exists is: the making for cam is had relatively high expectations, the technology more complicated, and cost is higher, and the balance of rotating disk is difficult for guaranteeing.
The utility model content
The purpose of this utility model be to provide a kind of simple and reasonable, cost of manufacture is low and can make the uniform microwave oven turntable lift rotating equipment of heating food more.
A kind of microwave oven turntable lift rotating equipment by this purpose design, comprise the cavity that is provided with cooking room, the rotary tray motor that driving force can be provided, drive and be arranged on rotating ring components on the cooking room bottom surface, be positioned over the rotating disk on the rotating ring components by rotary tray motor, be provided with the elevating and rotating machine structure between wherein above-mentioned rotary tray motor and the rotating ring components, above-mentioned lifting rotation comprises first rotating shaft and second rotating shaft that cooperatively interacts, first rotating shaft is installed in the rotating shaft of rotary tray motor, and second rotating shaft upper end is stretched in the furnace chamber and matched with rotating ring components.
The above-mentioned first rotating shaft cross section is T-shaped, and its upper end is the thin cylinder of level, and the lower end is an axle sleeve, and axle sleeve is sleeved in the rotating shaft of rotary tray motor; The above-mentioned second rotating shaft cross section is inverted T-shaped, and the thin axle in its upper end is installed in the rotating shaft axis hole of rotating ring components lower end, and the lower end is the long column body, and cylinder is provided with the recessed rail of helical form, and the thin cylinder periphery in first rotating shaft upper end cooperates with recessed rail.
Above-mentioned second rotating shaft is installed on the mounting bracket, and mounting bracket is installed in cavity bottom.
During the utility model work, rotary tray motor rotates, and drives first rotating shaft rotation, and first rotating shaft drives second rotating shaft and rotatablely moves do lifting, the second rotating shaft driven rotary ring assemblies is done lifting and is rotatablely moved, and rotatablely moves do lifting thereby also drive the rotating disk that is positioned on the rotating ring components.
The utility model is provided with the elevating and rotating machine structure owing to having adopted between rotary tray motor and rotating ring components, the elevating and rotating machine structure comprises first rotating shaft that cooperatively interacts and the structure of second rotating shaft, therefore, it is simple and reasonable, cost of manufacture is low, and can make turntable lift more steady, thereby guarantee that heating food more is even, heat effective.
