Problems solved by technology

[0014] The disadvantage of the drive structure of the metal turntable of the above-mentioned existing turntable microwave oven is: due to the special shape feature of the top of the connection part 70, it is very difficult to accurately connect the turntable 40 and the connection part 70
Because it is very difficult to connect between the metal turntable 40 and the connecting part 70, unnecessary trouble is brought to the user
[0017] In addition, if the connection between the metal turntable 40 and the connection part 70 is improper, the metal turntable 40 will be detached from the connection part 70 during the operation of the microwave oven.

Embodiment 1

[0035] Such as Figure 3a and Figure 3b As shown, the driving structure of the metal turntable of the microwave oven of the present invention includes: a metal turntable 410 made of metal material for holding food; a drive motor 60 driven by pressure to rotate the metal turntable 410; and a driving force of the drive motor 60 The connection part 70 passed to the metal turntable 410; the lower surface of the bottom surface of the metal turntable 410 is concavely formed with a combination groove 411 combined with the top of the connection part 70, and the upper surface of the bottom surface of the metal turntable 410 is formed with a The positioning mark 412 for confirming the bonding position of the connecting member 70 .

[0036] The lower end of the connecting member 70 is connected to the motor shaft of the driving motor 60 , so as to transmit the driving force of the driving motor 60 to the metal turntable 410 .

[0037] Since the metal turntable 410 is made of an opaque...

Embodiment 2

[0041] Such as Figure 4 As shown, the positioning mark 412 is a patch printed with a shape 414 combined with a groove 411 .

[0042] Furthermore, although not shown in the figure, a protrusion having the same shape as the coupling groove 411 may be integrally formed on the upper surface of the metal turntable 410 .

[0043] For example, when the shape of the top of the connecting part 70 is " " shape, the positioning mark 412 is formed as " ” shape, so that it is the same shape as the top of the connecting part 70; of the same shape.

[0044] In the present invention, the position where the positioning mark 412 is formed is located directly above the part where the groove 411 is formed, which makes position confirmation easier.

[0045] At this time, if the shape of the positioning mark 412 is the same as that of the combination groove 411 and they are located at the same position, the combination groove 411 should be formed by a stamping process. At this time, if the ...

Abstract

The invention discloses a driving structure of a metal turntable of a microwave oven, which comprises: a metal turntable made of metal material for containing food; a drive motor and a pressure-driven metal turntable; The connection part of the metal turntable; the lower surface of the bottom surface of the metal turntable is concavely formed with a combination groove combined with the top of the connection part, and the upper surface of the bottom surface of the metal turntable is formed with a positioning for confirming the bonding position of the connection part mark. The beneficial effect is: the structure is simple, the use is convenient, and the user can be accurately guided to accurately combine the metal turntable of the microwave oven with the connecting parts; in addition, the metal turntable of the microwave oven and the connecting parts form a firm combination, which can prevent Failure of the metal turntable to disengage from the connecting part.

Description

technical field [0001] The invention relates to a microwave oven, in particular to a driving structure of a metal turntable of the microwave oven. Background technique [0002] The working principle of the microwave oven is that the magnetron emits microwaves (the frequency is about 2450MHz) to the food in the microwave oven. Under the action of the microwaves, the food molecules containing moisture are repeatedly polarized, and friction occurs between the food molecules , so that the temperature of the food continues to rise to achieve the cooking effect on the food. [0003] In order to irradiate the microwaves emitted by the magnetron evenly on the food in the oven cavity, the food is placed on a constantly rotating turntable, and a stirring fan can also be set to disperse the microwaves entering the oven cavity evenly. Come. [0004] figure 1 It is an exploded schematic diagram of the drive structure of the metal turntable of the existing microwave oven; figure 2 It...
