The following describes each part of the pot detection device of the food processing appliance according to the embodiment of the present disclosure in detail:
the thyristor SCR1 is connected between the ac power source and the motor 3. Specifically, the first terminal of the SCR1 may be connected to the second terminal of the motor 3, the first terminal 100 of the motor 3 may be connected to the first terminal L of the ac power source, the second terminal 102 of the SCR1 may be connected to the second terminal N of the ac power source, and the control terminal 103 of the SCR1 may be connected to the control device 1. The alternating current power supply can be a commercial power supply. The first terminal L of the ac power supply may be an ac neutral line, and the second terminal N of the ac power supply may be an ac live line. The first terminal 101 of the thyristor SCR1 may be the cathode of the thyristor SCR1, and the second terminal 102 of the thyristor SCR1 may be the anode of the thyristor SCR 1. When the SCR1 is turned on, the ac power supply supplies power to the motor 3 to turn on the motor 3.
The control device 1 is connected with a silicon controlled rectifier SCR1 and is used for controlling the conduction of a silicon controlled rectifier SCR1 so as to enable the motor 3 to rotate. The control device 1 may be connected to the control terminal 103 of the SCR1, and is configured to input a trigger signal to the control terminal 103 of the SCR1, so as to turn on the SCR 1. The control device 1 of the embodiment of the present disclosure may include a controller and a zero-cross detection circuit. The zero-crossing detection circuit is used for detecting the zero-crossing point of alternating current output by the alternating current power supply, generating a zero-crossing signal when the zero-crossing point is detected, and sending the zero-crossing signal to the controller. The controller may be connected to the control terminal 103 of the SCR1, and is configured to input a trigger signal to the control terminal 103 of the SCR1 according to the zero-crossing signal, so as to turn on the SCR 1. For example, the controller controls the SCR1 to turn on after a time delay after the zero-crossing detection circuit detects the zero-crossing point of the alternating current. By controlling the time delay after the zero crossing, the controller can control the conduction angle of the SCR1 during one cycle of the ac. The conduction angle of the SCR1 may be 30 °, 35 °, 50 °, 60 °, etc., but the embodiment of the present disclosure is not limited thereto. The controller may be a single chip. The single chip microcomputer can be provided with a first port IO1 connected with the control terminal 103 of the SCR 1.
The speed measuring device 2 is used for detecting the rotating speed of the motor 3. The speed measuring device 2 may be a hall sensor, but the embodiment of the present disclosure is not limited to this. The hall sensor may include a power port, an input-output port, and a ground port. The speed measuring device 2 can also be connected to the control device 1 for transmitting the detected rotation speed to the control device 1. The hall sensor is connected to the control device 1 via an input/output port. Taking the example where the control device 1 described above includes a controller, the hall sensor is connected to the controller via an input/output port. Taking the controller as an example of a single chip, the single chip may be provided with a second port IO2 connected to the input/output port of the hall sensor. In addition, the pot detection device of the present disclosure may further include a first current limiting resistor R5 and a second current limiting resistor R6. The first current limiting resistor R5 is connected between the input/output port and the power supply port of the hall sensor. The second current limiting resistor R6 is connected between the input/output port of the hall sensor and the control device. The first current limiting resistor R5 and the second current limiting resistor R6 can limit the current in the circuit from being overlarge, and prevent the current from burning out components.
The control device 1 can also be used for judging whether the pot body 4 is arranged on the base 5 according to the rotating speed obtained by the detection of the speed measuring device 2. When the pot body 4 is arranged on the base 5, the rotating motor 3 drives the stirring mechanism 6 to rotate, namely, the motor 3 is in a loaded running state; when the pot body 4 is separated from the base 5, namely the pot body 4 is not arranged on the base 5, the rotating motor 3 is in an idle running state. When the conduction angle of the silicon controlled rectifier SCR1 is fixed, the rotating speed of the motor 3 in the loaded running state is different from the rotating speed of the motor 3 in the idle running state, so that whether the pot body 4 is installed on the base 5 can be accurately judged according to the rotating speed detected by the speed measuring device 2. Wherein, the control device 1 is used for judging whether the pot body 4 is arranged on the base 5 according to the rotating speed after the rotating speed value detected by the speed measuring device 2 is kept unchanged in the preset time. The preset time may be 2s, but the embodiment of the present disclosure is not limited thereto. In addition, the control device 1 can determine whether the pot 4 is mounted on the base 5 before the cooking process is started. Of course, the control device 1 can also determine whether the pan body 4 is mounted on the base 5 after the cooking process is started. For example, when the cooking process selected by the user requires low-speed stirring for 5 minutes and then high-speed stirring for 3 minutes, the control device 1 may determine whether the pot 4 is mounted on the base 5 after the low-speed stirring is started, continue the stirring if the determination result is that the pot 4 is mounted on the base 5, and terminate the stirring if the determination result is that the pot 4 is not mounted on the base 5.
Further, the control device 1 is used for comparing the rotation speed detected by the speed measuring device 2 with a speed threshold, and determining whether the pot 4 is mounted on the base 5 according to the comparison result of the rotation speed and the speed threshold. The control device 1 is used for judging that the pot body 4 is arranged on the base 5 when the rotating speed is less than or equal to a speed threshold value, and is used for judging that the pot body 4 is not arranged on the base 5 when the rotating speed is greater than the speed threshold value. When the pot body 4 is arranged on the base 5, the rotating motor 3 is in a loaded running state, and the rotating speed is low; when the pot body 4 is separated from the base 5, the rotating motor 3 is in an idle running state, and the rotating speed is higher. Therefore, the present disclosure can accurately and rapidly determine whether the pot 4 is mounted on the base 5 according to the comparison result between the rotation speed detected by the speed measuring device 2 and the speed threshold. In addition, the control device 1 is also used for controlling the silicon controlled rectifier SCR1 to cut off when the rotation speed detected by the speed measuring device 2 is greater than the speed threshold value, so as to disconnect the motor 3 from the alternating current power supply.
The pot detection device of the present disclosure may further include an absorption circuit. The snubber circuit is connected in parallel with the thyristor SCR1 to protect the thyristor SCR1 from false triggering. The snubber circuit may include a first resistor R1 and a first capacitor C1 connected in series, and the first resistor R1 and the first capacitor C1 connected in series between the first terminal 101 of the SCR1 and the second terminal 102 of the SCR 1. In an embodiment of the present disclosure, a first end 104 of the first resistor R1 is connected to a second end 102 of the SCR1, a first end 105 of the first capacitor C1 is connected to a second end of the first resistor R1, and a second end of the first capacitor C1 is connected to a first end 101 of the SCR 1. In another embodiment of the present disclosure, the first terminal 104 of the first resistor R1 is connected to the first terminal 101 of the SCR1, the first terminal 105 of the first capacitor C1 is connected to the second terminal of the first resistor R1, and the second terminal of the first capacitor C1 is connected to the second terminal 102 of the SCR 1.
The pot detection device of the present disclosure may further include a pull-up resistor R2. The first terminal 106 of the pull-up resistor R2 is connected to the control terminal 103 of the thyristor SCR1, and the second terminal of the pull-up resistor R2 is connected to the second terminal 102 of the thyristor SCR 1. The pull-up resistor R2 can improve current and voltage, solve the problem of current supply when the driving capability is insufficient, and ensure the effective work of the silicon controlled SCR 1. The pot detection device of the present disclosure may further include a drive current limiting resistor. The driving current limiting resistor may be connected between the control terminal 103 of the SCR1 and the control device 1. The driving current limiting resistor may include a first driving current limiting resistor R3 and a second driving current limiting resistor R4 connected in series.
The embodiment of the disclosure also provides a food processing appliance. The food processing appliance may comprise a pot 4 and a stand 5. The pot body 4 can be internally provided with a stirring mechanism 6. The base 5 may be provided with a motor 3 and a pot detection device of the food processing appliance according to any of the above embodiments. The motor 3 can drive the stirring mechanism 6 to rotate when the pot body 4 is arranged on the base 5. The food processing appliance can be a cooking machine, a food processor, a dough mixer and the like. Since the pan detection device of the food processing appliance of the embodiment of the present disclosure is the same as the pan detection device of the embodiment of the pan detection device, the same advantageous effects are obtained, and the detailed description of the present disclosure is omitted.
Although the present disclosure has been described with reference to a preferred embodiment, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the disclosure.
