Description

Double-rotation barbecue device

Technical Field

The invention relates to a household oven, a microwave oven and a light wave oven.

Background

The technical proposal of 'a double-rotation barbecue device' disclosed in Chinese patent No. 2016111955890 provides a double-rotation barbecue device which does not need to change the structure of the prior transmission device and a grill chassis and does not increase the energy consumption and the cost, and the technical conception is as follows: the scheme has the defect that the instantaneous current of the reversing rotation of the driving motor is very high, and if no overcurrent protection measure is provided, the coils of the motor can be burnt. The grill is used for carrying food with huge moment of inertia due to the fact that the grill has huge moment of inertia, and the food is huge load instantly in the reverse direction; in addition, the scheme is only suitable for the bidirectional motor, and has defects in both applicability and economy.

Detailed Description

The invention is further described below with reference to the figures and examples.

Example 1

Referring to fig. 1-4, the present embodiment includes an annular cooking cavity 1, a dual-rotation grill 2, a driving motor 3, and an electric control device 4, wherein the grill 2 includes a chassis 2.1, a pillar 2.2, an upper beam 2.3, and a combined carrier 2.4, the combined carrier includes an annular upper cover 2.41, a driving gear 2.42, and a lower cover 2.43, the outer side of the inner wall 2.412 of the annular upper cover 2.41 is provided with a tooth engaged with the driving gear 2.42 for generating a rotation motion around its own axis when the driving gear 2.42 rotates with the grill 2, the inner sides of the inner wall 2.412 of the annular upper cover 2.41 and the upper cover 2.41 are provided with a counterweight beam 2.413, a hanging counterweight 2.414 is provided at the center of the beam for increasing the moment of inertia of the upper cover, the electric control device 4 controls the driving motor 3 to run to get rid of the driving gear of the upper cover 2.41 following the driving gear to make it rotate relative to the above 2.42, specifically, whenever the upper cover 2.41 is rotated synchronously with/after the grill 2, the driving motor 3 is stopped, because the upper cover 2.41 is set to be rotatable, when the driving motor 3 is stopped, the rotation is not stopped immediately, but is rotated for a period of time under the driving of inertia, which causes the driving gear 2.42 engaged with the driving motor to rotate around the self axis, when the upper cover 2.41 is stopped or is about to be stopped, the driving motor 3 is restarted, because the upper cover 2.41 can rotate and has inertia, the driving motor 3 is not rotated synchronously with the grill 2 immediately, thereby causing the driving gear 2.42 to rotate relatively to the driving gear 2.42, causing the driving gear 2.42 to generate the rotation around the self axis, so as to realize double rotation barbecue, when in actual application, the driving motor 3 can be set to be in an intermittent operation mode, and the operation time is equal to the time required when the upper cover 2.41 is rotated synchronously with the grill 2, the interval time of the operation is made equal to the time required when the speed at which the upper cover 2.41 is rotated from the synchronous rotation is 0 speed, which is obtained by the experiment. Because the driving motor 3 is not required to rotate reversely, a bidirectional motor is not required to be used, and huge steering overload current does not exist, so that compared with the prior art, the steering overload current-free device has the beneficial technical effects of being low in cost, small in energy.

Example 2

Compared with the embodiment 1, the present embodiment is mainly distinguished in that the running time of the driving motor 3 is set as the time required for the upper cover 2.41 to reach 4/5 of the rated rotating speed of the grill 2, and the interval time is set as the time required for the rotating speed of the upper cover 2.41 to be reduced from 4/5 of the rated rotating speed of the grill 2 to 1/5 of the rated rotating speed of the grill 2, so that the advantages of shortening the running interval time of the driving motor 3, namely shortening the rotating time of a food unit and improving the uniformity of barbecue are achieved. Otherwise, the same as example 1 was not mentioned.

It should be noted that all the equivalent transformation, or different expressions with the same essential meaning, which are directly or indirectly applied to other related technical fields, made by using the contents of the present specification and the attached drawings, are within the protection scope of the present invention.
