Detailed Description
Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are illustrative and intended to be illustrative of the invention and are not to be construed as limiting the invention.
A control device of a cooking machine and a cooking machine having the same according to embodiments of the present invention are described below with reference to the accompanying drawings.
Fig. 1 is a block schematic diagram of a control device of a cooking machine according to one embodiment of the present invention. As shown in fig. 1, the control apparatus of a cooking machine according to an embodiment of the present invention may include: a heating control module 10, a gating module 20, a motor control module 30, and a function selection module 40.
Wherein, the power end of the heating control module 10 is directly connected with the power supply 50. The power source terminal of the motor control module 30 is connected to the power supply 50 through the gating module 20, and the heating control module 10 and the motor control module 30 are disposed on different circuit boards. The function selection module 40 is respectively connected to the heating control module 10, the gating module 20 and the motor control module 30, and the function selection module 40 is configured to output a heating control signal to the heating control module 10 according to a control instruction of a user, so that the heating control module 10 performs heating control according to the heating control signal, and/or output a gating signal to the gating module 20, so that the power supply 50 supplies power to the motor control module 30, and output a motor control signal to the motor control module 30, so that the motor control module 30 controls the motor according to the motor control signal.
Specifically, at present, more and more cooking machines begin to utilize IH (Induction Heat) principle to Heat, and the stirring and chopping functions of motor products are added in the cooking machines to realize a multi-function, but in the design of the electric control board of this type of products, the module for controlling electromagnetic heating and motor rotation is usually arranged on the same main control board, so that the electromagnetic interference generated on the main control board is the most. Therefore, in order to avoid crosstalk and superposition between the two modules which generate much electromagnetic interference, the two modules are separately arranged, that is, the heating control module 10 and the motor control module 30 are arranged on different circuit boards and have independent main control chips.
Meanwhile, the heating control module 10 and the motor control module 30 are provided with different power supply loops, that is, the heating control module 10 is directly connected with the power supply 50, and the motor control module 30 is connected with the power supply 50 through the gating module 20, so that when the motor control module 30 does not work, the power supply 50 is disconnected from the motor control module 30 through the gating module 20, and the standby power consumption of the whole machine is reduced.
For example, after the cooking machine is powered on to operate, the user selects a desired function through the function selection module 40. When the user selects only the heating function, the function selection module 40 outputs a heating control signal to the heating control module 10 according to the heating control command, so that the heating control module 10 performs heating according to the heating control signal. At this time, since the user does not select the motor function, the gate module 20 is in the off state, and the power supply 50 does not supply power to the motor control module 30, which is favorable for meeting the requirement of low power consumption in the IEC (International Electrotechnical Commission) standard, and thus, when designing the electric control board, it is only necessary to debug the standby power consumption of the electromagnetic heating portion to be qualified.
When the user selects only the motor function, the function control module 40 sends a gating signal (such as a high level signal) to the gating module 20 to make the gating module 20 in a closed state, the power supply 50 supplies power to the motor control module 30, and meanwhile, the function control module 40 also sends a motor control signal to the motor control module 30 to make the motor control module 30 control the motor according to the motor control signal.
When a user selects both the heating function and the motor function, the function selection module 40 outputs a heating control signal to the heating control module 10 according to the heating control instruction, so that the heating control module 10 performs heating control according to the heating control signal, and meanwhile, the function selection module 40 also outputs a gating signal to the gating module 20 according to the motor control instruction, so that the gating module 20 is in a closed state, the power supply 50 supplies power to the motor control module 30, and sends a motor control signal to the motor control module 30, so that the motor control module 30 controls the motor according to the motor control signal, and simultaneous work of electromagnetic heating and motor stirring can be realized.
Therefore, according to the control device of the cooking machine provided by the embodiment of the invention, the heating control module and the motor control module are arranged on different circuit boards and are provided with independent power supply loops, so that the electromagnetic crosstalk and superposition among the modules can be effectively avoided, the difficulty in solving the problem of electromagnetic interference is reduced, the standby power consumption of the whole machine is effectively reduced, meanwhile, the universality of the modules is enhanced, and the appropriate schemes can be combined at will.
It will be appreciated that in embodiments of the present invention, as shown in fig. 2, the power supply 50 may comprise a filter module 51, wherein the power supply terminal of the heating control module 10 is directly connected to the output terminal of the filter module 51, and the power supply terminal of the motor control module 30 is connected to the output terminal of the filter module 51 through the gating module 20.
That is, by providing the filtering module 51 at the output port of the power supply 50 to filter the external interference, the interference of the power supply to the outside is reduced. When the filter module 51 is designed and debugged, the electromagnetic heating filter module and the motor rotation filter module can be combined and simplified, so that the heating control module 10 and the motor control module 30 share one filter module 51, thereby not only simplifying the circuit and reducing the electromagnetic interference of the whole machine to the minimum, but also not worrying about the influence of the change of the filter module on other circuit boards.
Further, according to an embodiment of the present invention, when the control command of the user is a heating function command, the function selection module 40 outputs a heating control signal to the heating control module 10; when the control instruction of the user is a motor function instruction, the function selection module 40 outputs a gating signal to the gating module 20 and outputs a motor control signal to the motor control module 30; when the control command of the user is a heating/motor one-key check function command, the function selection module 40 outputs a heating control signal to the heating control module 10, and outputs a gating signal to the gating module 20, and outputs a motor control signal to the motor control module 30.
Specifically, as shown in fig. 2, the function selection module 40 may include a function key with a heating/motor one-key check (heating and motor combined operation), a function key with a single-control motor, and a function key with a single-control heating, which are all directly facing to the user, and each type of function may be extended with one or more function selections for the user to select, for example, when the user presses the function key with a heating/motor one-key check, the function selection module 40 simultaneously issues a heating function command, a gating command, and a motor function command, outputs the heating function command to the heating control module 10 to control heating, and outputs a gating signal to the gating module 20 to make the gating module 20 in a closed state, and the motor control module 30 is powered on and transmits the motor function command to the motor control module 30 to control the motor to operate. Therefore, the electromagnetic heating function and the motor rotation function are synchronously realized.
The heating/motor one-key check type function keys have preset control working modes, and when the type of function keys are selected, the food can be directly processed and cooked according to the preset modes without independently setting the heating power or the motor rotating speed and the like. And the function keys of the single control heating type and the function keys of the single control motor type automatically adjust the heating power and the motor rotating speed according to the actual requirements of customers. For example, when a user selects a heating/motor one-key check function, the function selection module 40 directly sends preset control information to the corresponding main control chip, and controls the corresponding module to directly start working according to a preset mode; if the user separately and respectively sets the rotating speed and the heating power, the functional module with the corresponding function respectively sends the information selected by the user to the corresponding module, and then the operation is started according to the information set by the user.
Specifically, after the cooking machine is powered on, the selection information of the user is received and transmitted by the function selection interface facing the user. When the user selects a function key of a heating/motor one-key check type, the function selection module 40 sends a gating signal to the gating module 20 to power on the control motor module 30, and simultaneously transmits preset information of the check function to the heating control module 10 and the motor control module 30 to enable the heating control module 10 and the motor control module 20 to perform heating and motor operation according to preset program control.
When the user separately sets the heating function, the function selection module 40 transmits the heating power and mode set by the user to the heating control module 10 so that the heating control module 10 controls heating according to the parameters set by the user.
When a user sets the motor function independently, the function selection module 40 firstly sends a gating signal to the gating module 20, so that the gating module 20 is in a closed state, the motor control module 30 is powered on, and the motor control module 30 receives the rotating speed and the rotating mode of the motor set by the user and controls the motor to work according to the motor parameter set by the user.
In an embodiment of the present invention, the gating module 20 and the heating control module 10 may be disposed on the same circuit board, and the gating module 20 and the heating control module 10 share the same main control chip.
That is, the gating module 20 may be disposed on the electronic control board of the heating control module 10, and the user selection information received by the function selection module 40 is transmitted to the main control chip of the heating control module 10. And the master control chip of the heating control module 10 receives and transmits the strobe signal to control the opening or closing of the strobe module 20. At this time, the heating control module 10 is used as a leading module to switch or select whether to select the electronic control module 30, which not only reduces the circuit layout, but also omits the communication between the gating module and the function selection module, and speeds up the data transmission rate.
Further, according to an embodiment of the present invention, as shown in fig. 3, the gating module 20 may include: a Relay, a first diode D1, a first resistor R1 and a controllable switch Q1. Wherein, the normally open contact of the Relay is connected in series in the loop between the power end of the motor control module 30 and the power supply 50; the anode of the first diode D1 is connected with one end of the relay coil, and the cathode of the first diode D1 is connected with the other end of the relay coil; one end of the first resistor R1 is connected to the cathode of the first diode D1, and the other end of the first resistor R1 is connected to the preset power VCC; the control end of the controllable switch Q1 is connected to the main control chip of the heating control module 10 through a second resistor R2, the control end of the controllable switch Q1 is also connected to the first end of the controllable switch Q1 through a first capacitor C1 and then grounded, and the second end of the controllable switch Q1 is connected to the anode of a first diode D1. The controllable switch Q1 may be an NPN transistor or a PNP transistor, and the difference is that the gating signals sent by the main control chip of the heating control module 10 are different.
Specifically, the controllable switch Q1 is an NPN transistor for example. When a user selects a function key of a heating/motor one-key check type or a function key of a single control motor type, the main control chip of the heating control module 10 receives and sends a communication signal (such as a high-level signal), at this time, the controllable switch Q1 is in a conducting state, and the Relay is powered on and closed, so that the power supply 50 supplies power to the motor control module 30; when the user selects the single control heating function key, the main control chip of the heating control module 10 does not send the gating signal, the Relay is still in the off state, and the power supply 50 stops supplying power to the motor control module 30.
It is understood that the gating module 20 may use not only relays, but also other switching schemes, and the main purpose is to gate the motor control module 30 to realize the motor function.
According to an embodiment of the present invention, as shown in fig. 3, the control device of the cooking machine may further include a display module 60, the display module 60 is connected to the function selection module 40, and the display module 60 is configured to feed back a control command of the user to the user. The display module 60 may include one or more of an LED lamp, a nixie tube, and a liquid crystal screen.
That is, after the user selects the corresponding function key, the function selecting module 40 sends the control instruction of the user to the corresponding control module, and simultaneously sends the function selected by the user to the display module 60 for feedback to the user. The display module 60 may be a separately arranged liquid crystal display, or may be integrally arranged on the function selection module 40, for example, the function selection module 40 has a liquid crystal display.
In addition, the design scheme and the design idea of the control device of the cooking machine of the embodiment of the invention can also be extended to other products with combined boundary-crossing functions (such as the combination of electromagnetic heating and motor rotation functions), and one function is used for mainly switching and selecting the other function (namely, one function module is used as a main function and one function is used as an auxiliary function). Aiming at the products with the function combination of the cross-boundary, under the condition of reducing the mutual influence of electromagnetic interference as much as possible, the placing positions of the circuit boards are slightly different according to the product types, but the basic principles are the same, and the circuit boards are arranged according to the current flow direction. For example, the current enters from the power line, then passes through the circuit board where the filter module 51 is located, then enters the main control board of the heating control module 10, and enters the main control board of the motor control module 30 from the main control board lead-out wire of the heating control module 10.
In addition, for a cooking machine with a heating function, a fan 70 is usually provided, as shown in fig. 4 and 5, the fan 70 may be disposed at a corner, the fan 70 blows from the corner to other directions, and two wind blocking ribs are disposed between the heating control module 10 and the fan 70 to intensively dissipate heat from the heating control module 10 (mainly because the heating control module 10 generates more heat from electric components such as IGBTs and rectifier bridges on the main control board, and the requirement for temperature is high). Due to the arrangement, electromagnetic interference and influence among circuit boards with various functions can be reduced, and meanwhile, the fan is used for radiating heat to prevent electric elements from being damaged due to overhigh temperature.
It should be noted that, the positions of the fan 70 and the power line inlet may be adjusted first, and then other layouts along the current inlet direction may be adjusted, wherein products without the fan 70 or with the fan 70 not lying flat may be provided, and other functional modules may be placed at the position of the fan 70. In addition, when the circuit board of the three-dimensional structure product is designed, the circuit board can be placed vertically.
In summary, according to the control device of the cooking machine in the embodiment of the present invention, the power end of the heating control module is directly connected to the power supply, the power end of the motor control module is connected to the power supply through the gating module, and the heating control module and the motor control module are disposed on different circuit boards, and the function selection module outputs the heating control signal to the heating control module according to the control instruction of the user, so that the heating control module performs heating control according to the heating control signal, and/or outputs the gating signal to the gating module, so that the power supply supplies power to the motor control module, and outputs the motor control signal to the motor control module, so that the motor control module controls the motor according to the motor control signal. Therefore, electromagnetic crosstalk and superposition between electromagnetic heating and motor functions can be reduced to the maximum extent, and meanwhile, the standby power consumption of the whole machine is effectively reduced.
