Abstract

The utility model relates to a device for controlling rotating and stopping of a microwave oven grill. a first rotating shaft and a second rotating shaft are respectively arranged at two ends of the grill; the first rotating shaft is located on a bracket on the right sidewall of an oven chamber and is in rotary fit with the bracket; a motor is fixed on the left sidewall of the oven chamber; an output shaft of the motor is connected with the second rotating shaft; the motor is a synchronous motor which is provided with a Hall element; a magnetic element matched with the Hall element is arranged on the second rotating shaft; the Hall element is connected with an input end of the controller; and the synchronous motor is connected with an output end of the controller. By matching of the Hall element and the magnetic element, the device is capable of judging and fixing the initial position of the motor and eliminating accumulated errors in a time control phase process, is also capable of controlling overturning, pause and stopping of the motor by using the controller, so as to control the overturning, pause and stopping of the microwave oven grill; and moreover, by adopting the synchronous motor, the cost is reduced.

Description

Be used for controlling the device that microwave oven grill rotates, stops

Technical field

The utility model relates to a kind of device for controlling the microwave oven grill rotation, stopping.

Background technology

At present, micro-wave oven with baking function on market adopts asynchronous machine to control the rotation of grill mostly, grill under this mode is random running, be that grill operation or the position when stopping are fixing, the concrete stop position of the uncontrollable grill of asynchronous machine namely, the easy like this drawback of getting thing inconvenience that causes; If adopt stepper motor to control the rotation of grill, although can control the anglec of rotation of grill, namely can control the stop position of grill, the cost of stepper motor is high, causes the micro-wave oven holistic cost to rise.

The utility model content

The purpose of this utility model is to provide the device that is used for the rotation of control microwave oven grill, stops that a kind of cost is low, can control the microwave oven grill rotation, stop.

for achieving the above object, the utility model has adopted following technical scheme: a kind of for controlling the microwave oven grill rotation, arresting stop, described grill is placed in furnace chamber, and the two ends of grill are respectively equipped with first, the second rotating shaft, first, the center line of the second rotating shaft matches, wherein, the first rotating shaft is placed on the support of furnace chamber right side wall and is configured to this and is rotatably assorted, be fixed with motor on the furnace chamber left side wall, the output shaft of motor is connected with the second rotating shaft, described motor is synchronous motor, and synchronous motor is provided with Hall element, the second rotating shaft is provided with the magnetic element that matches with Hall element, described Hall element is connected with the input of controller, synchronous motor is connected with the output of controller.

The coaxial fixed disk that is provided with in described the second rotating shaft, the mutually close card of fixed disk and synchronous motor is provided with the magnetic element that matches with Hall element.

As shown from the above technical solution, the utility model is by arranging Hall element on motor, in the second rotating shaft, magnetic element is set, by coordinating of Hall element and magnetic element, can judge and the initial position of fixed electrical machinery and the accumulated error in elimination time control phase process, can control upset, time-out and the location of motor by controller, thereby control upset, time-out and the location of grill, this motor adopts common synchronous motor simultaneously, with respect to stepper motor, reduced cost.

Description of drawings

Fig. 1 is structural representation of the present utility model;

Fig. 2 is the structural representation that the utility model grill is connected with motor.

The specific embodiment

Below in conjunction with accompanying drawing, the utility model is described further:

as Fig. 1, shown in Figure 2 is a kind of for controlling the microwave oven grill rotation, the device that stops, grill 1 is placed in furnace chamber, and the two ends of grill 1 are respectively equipped with first, the second rotating shaft 2, 3, first, the second rotating shaft 2, 3 center line matches, wherein, the first rotating shaft 2 is placed on the support 4 of furnace chamber right side wall and consists of with this support 4 and is rotatably assorted, be fixed with motor on the furnace chamber left side wall, the output shaft of motor is connected with the second rotating shaft 3, as preferred version of the present utility model, motor is selected synchronous motor 5, and synchronous motor 5 is provided with Hall element 6, the second rotating shaft 3 is provided with the magnetic element 7 that matches with Hall element 6, be exactly the coaxial fixed disk 8 that is provided with in the second rotating shaft 3 specifically, the mutually close card of fixed disk 8 and synchronous motor 5 is provided with the magnetic element 7 that matches with Hall element 6, Hall element 6 is connected with the input of controller, synchronous motor 5 is connected with the output of controller.

In sum, the utility model is by arranging Hall element 6 on motor, in the second rotating shaft 3, magnetic element 7 is set, by coordinating of Hall element 6 and magnetic element 7, can judge and the initial position of fixed electrical machinery and the accumulated error in elimination time control phase process, can control upset, time-out and the location of motor by controller, thereby control upset, time-out and the location of grill 1, this motor adopts common synchronous motor 5 simultaneously, with respect to stepper motor, reduced cost.
