Description
Technical field
The present invention relates to a kind of micro-wave oven.Particularly relate to the microwave oven turntable drives structure that a kind of food that makes to be cooked can be got back to initial position when end of cooking.
Background technology
Micro-wave oven is a kind of cooking product that utilizes microwave and resistance heat to heat food.In the cooking room that microwave oven internal forms, possess rotating disk, to food is rotated, make its thermally equivalent.
Fig. 1 is the micro-wave oven significant points decomposing schematic representation of conventional art; Fig. 2 is the microwave oven turntable whirligig sectional schematic diagram of conventional art.As shown in the figure, play the inner cooking room 11 that forms of housing 10 of micro-wave oven framework effect.In cooking room 11, utilize microwave homenergic, carry out the culinary art of food.The centre of housing 10 bottom surfaces forms through hole 11a.Run through this through hole 11a and be provided with turntable shaft 17.
Cooking room 11 bottom center positions, arrange rotating disk 13 by rotatable mode.While cooking, rotating disk 13 top accommodating foods.As shown in Figure 2, rotating disk 13 bottom center positions, form driver slot block 13a.This driver slot block 13a is connected with the turntable shaft 17 that runs through this through hole 11a.
In the bottom of housing 10, rotary tray motor 15 is set.This rotary tray motor 15, for rotating disk 13 provides power, allows rotating disk 13 be rotated.The upper turntable shaft 17 that inserts of rotating disk output shaft 15a.This turntable shaft 17 is sent to the power of rotary tray motor 15 in rotating disk 13.
As shown in Figure 2, the lower end part of turntable shaft 17 is inserted on the output shaft 15a of motor 15, and its upper-end part of driving connects the through hole 11a that housing 10 bottom surfaces form, and is exposed at the inside of cooking room 11.
As shown in Figure 3, the upper-end part of driving of turntable shaft 17 forms several driving wing 17a across certain intervals.Drive wing 17a to combine with the driver slot block 13a of rotating disk 13.Thereby, the driving force of rotary tray motor 15 can be transmitted to rotating disk 13 by turntable shaft 17.Both sides at turntable shaft 17 lower end parts have hook 17b.This hook 17b can prevent that turntable shaft 17 from departing from from the through hole 11a of housing 10.
Between the bottom surface of housing 10 and rotating disk 13, be provided with rotating ring assembly 19.This rotating ring assembly 19 can supporting wheel 13, allows rotating disk 13 rotate swimmingly.Rotating ring assembly 19 is comprised of ring body 19a, scroll wheel 19b conventionally.And ring body 19a makes with metal material conventionally, it is shaped as annular.Scroll wheel 19b is formed on the below of ring body 19a, supports ring body 19a, and can rotate.
Unaccounted symbol 21 is electric control chamber.In electric control chamber, be provided with various electrical parts, can allow magnetron produce microwave.
In conventional microwave oven, the power of rotary tray motor 15 transmits to rotating disk 13 by turntable shaft 17 as constructed as above.Thereby, allow rotating disk 13 be rotated.And be placed on the food of rotating disk 13 tops, and when being rotated, by microwave or resistance heat, heated, cook.
But, existing micro-wave oven as above, on the rotating disk 13 of food being put into cooking chamber for microwave oven, arrange, after cooking finishes, food stops at position (being likely parked in body of heater backmost) arbitrarily with rotating disk 13, food temperature is higher in addition, for user takes out food, causes some difficulty.
Summary of the invention
Technical problem to be solved by this invention is that providing a kind of can locate rotating disk after end-of-job, gets back to the microwave oven turntable drives structure of initial position.
The technical solution adopted in the present invention is: a kind of microwave oven turntable drives structure, include the cooking room being arranged in micro-wave oven casing, portion of cooking room bottom center is provided with rotating disk by rotatable mode, the centre of cooking room bottom surface forms through hole, running through this through hole is provided with for driving the turntable shaft of rotating disk, bottom at cooking room is provided with rotary tray motor, the output shaft of described rotary tray motor is connected with described turntable shaft, for the power of rotary tray motor is sent to rotating disk, on described output shaft, be fixedly installed a cam, in the salient point institute of described cam through locating to arrange a microswitch, described microswitch is electrically connected to microwave oven control panel.
Described microswitch is fixedly installed on rotary tray motor, and described microswitch is corresponding with the salient point of cam to be arranged and for contacting, is connected with described cam at this point.
Described microswitch is fixedly installed on the micro-wave oven casing below cooking room, and described microswitch is corresponding with the salient point of cam to be arranged and for contacting, is connected with described cam at this point.
Microwave oven turntable drives structure of the present invention, arranges simply, does not need to change the overall structure that former microwave oven turntable drives, and only in rotary tray motor rotating shaft bottom, fixes a cam and goes out to arrange a microswitch at cam salient point, just can control the position that rotating disk stops.Thereby can make the rotating disk of micro-wave oven locate after end-of-job, get back to initial position, facilitate user to take out easily food.

The specific embodiment
Below in conjunction with embodiment and accompanying drawing, microwave oven turntable drives structure of the present invention is described in detail.
As shown in Figure 4, Figure 5, microwave oven turntable drives structure of the present invention, includes the cooking room 1 being arranged in micro-wave oven casing, and this cooking room 1 provides cooking space for food.Cooking room 1 portion of bottom center is provided with rotating disk 2 by rotatable mode, and rotating disk 2 tops are for placing the food 8 being cooked.The centre of cooking room 1 bottom surface forms through hole, running through this through hole is provided with for driving the turntable shaft 3 of rotating disk 2, in the bottom of cooking room 1, be provided with rotary tray motor 4, the output shaft 5 of described rotary tray motor 4 is connected with described turntable shaft 3, for the power of rotary tray motor 4 is sent to rotating disk 2, on described output shaft 5, be fixedly installed a cam 6, it can be rotated with the output shaft 5 of rotary tray motor.In the salient point institute of described cam 6, through locating to arrange a microswitch 7, make one week salient point of the every rotation of cam 6 can touch microswitch 7.Described microswitch 7 is electrically connected to microwave oven control panel.
Described microswitch 7 is fixedly installed on cooking room 1 micro-wave oven casing below, and described microswitch 7 is corresponding with the salient point of cam 6 to be arranged and for contacting, is connected with described cam 6 at this point.
Microwave oven turntable drives structure of the present invention, during work, is rotated in the food of the needs cooking on rotating disk 2, and rotating disk 2 starts to rotate at initial position (salient point of cam 6 contacts with microswitch 7) under the driving of rotary tray motor 4.When rotating disk 2 starts to rotate, every rotation one week cam 6 contacts once with microswitch, to control panel, sends a signal, but at this moment because control panel is not received the indication stopping operating, so rotary tray motor 4 drives rotating disk 2 rotations always.
When the cooking stops, rotating disk 2 goes to after initial position (position that cam 6 contacts with microswitch 7) under the driving of rotary tray motor 4, microswitch 7 sends signal to control panel, at this moment because control panel is received the indication stopping operating, so at this moment microwave oven control panel control rotary tray motor quits work.
