Embodiment Construction

[0014] The present invention will be further described below in conjunction with accompanying drawing:

[0015] Such as figure 1 , figure 2 A device for controlling the rotation and stop position of a microwave oven grill is shown. The grill 1 is placed in the oven cavity, and the two ends of the grill 1 are respectively provided with first and second rotating shafts 2 and 3. The first and second The centerlines of the rotating shafts 2 and 3 coincide, wherein the first rotating shaft 2 is placed on the support 4 on the right side wall of the furnace cavity and forms a rotation fit with the support 4, a motor is fixed on the left side wall of the furnace cavity, and the output shaft of the motor Linked to the second rotating shaft 3, as a preferred solution of the present invention, the motor selects a synchronous motor 5, and the synchronous motor 5 is provided with a Hall element 6, and the second rotating shaft 3 is provided with a magnetic element 7 matched with the Hall...

Abstract

The present invention relates to an apparatus for controlling rotation and stopping of a microwave oven grill, wherein both ends of the grill are respectively provided with a first rotation shaft and a second rotation shaft, the first rotation shaft is placed on a bracket on the right side wall of a microwave oven cavity, and forms rotation matching with the bracket, the left side wall of the microwave oven cavity is fixed with a motor, an output shaft of the motor is connected with the second rotation shaft, the motor is a synchronous motor and is provided with a hall element, the second rotation shaft is provided with a magnetic element matched with the hall element, the hall element and an input end of a controller are connected, and the synchronous motor and an output end of the controller are connected. The present invention further discloses a controlling method for controlling the apparatus for controlling rotation and stopping of the microwave oven grill. According to the present invention, matching of the hull element and the magnetic element is adopted, such that the initial position of the motor can be determined and fixed, accumulated errors during a time control phase process can be eliminated; and the controller can be adopted to control flipping, pausing and positioning of the motor so as to control flipping, pausing and positioning of the grill; and the synchronous motor is adopted so as to reduce cost.

Description

technical field [0001] The invention relates to a device for controlling the rotation and stop of a microwave oven grill and a control method thereof. Background technique [0002] At present, most microwave ovens with barbecue function on the market use asynchronous motors to control the rotation of the grill. In this way, the grill operates randomly, that is, the position of the grill when it is running or stopping is not fixed, that is, the asynchronous motor cannot control the rotation of the grill. The specific stop position of the grill will easily cause the disadvantage of inconvenient picking; if a stepping motor is used to control the rotation of the grill, although the rotation angle of the grill can be controlled, that is, the stop position of the grill can be controlled, but the stepping motor The high cost of the motor results in an increase in the overall cost of the microwave oven. Contents of the invention [0003] The primary purpose of the present invent...
