Description
Technical Field
The present invention relates to the field of kitchen devices, and in particular, to a kitchen device, a control method thereof, and a computer-readable storage medium.
Background
In the related art, a range hood includes a soot inlet and a panel for closing and opening the soot inlet. When the range hood does not work, the panel closes the oil smoke inlet to keep attractive and tidy, and when the range hood works, the panel opens the oil smoke inlet, and the fan operates to suck oil smoke from the oil smoke inlet. Generally, a motor (such as a dc brush motor) is generally used for opening and closing the panel, and currently, a position sensor or a method for detecting that a current value of the dc motor reaches a certain threshold is generally used for determining that the panel is opened and closed in place. However, due to various factors such as the batch consistency of the motor, the temperature of the use environment, the size deviation of the parts of the opening and closing transmission system, and the external interference (the movement of the panel is prevented by hands), the current value output by the direct current motor when the panel is closed is deviated, or the panel is judged in place by mistake in advance. Finally, the panel of the range hood is not opened and closed in place, and the panel is still at an opening angle under the condition that the panel is not closed in place, so that the appearance is not attractive, and small animals are easy to enter the range hood to damage electric devices. Under the condition that the panel is not opened in place, the effective area for sucking the oil smoke is reduced easily, and the oil smoke sucking efficiency is poor.

Referring to fig. 1 and 2, a control method according to an embodiment of the present invention is applied to a kitchen device 10. The kitchen device 10 includes a range hood, an integrated cooker, and the like having a function of discharging oil smoke. It can be understood that the range hood can be a variable frequency range hood. The integrated cooker comprises a range hood, and the range hood can be a frequency conversion range hood. The kitchen device 10 is described in detail below as an example of a range hood.
The kitchen unit 10 comprises a cooking fume inlet 12, a motor 14 and a movable shutter 16. The shielding portion 16 is used to shield the soot inlet 12. The motor 14 is connected to the shielding portion 16 and is used to drive the shielding portion 16 to move to open and close the lampblack inlet 12. It will be appreciated that the kitchen utensil 10 also includes a cigarette maker body 11, with the curtain 16 being connected to the cigarette maker body 11. The cigarette machine body 11 is provided with a lampblack inlet 12. The shielding portion 16 is movably disposed at the smoke inlet 12, and the motor 14 drives the shielding portion 16 to move to control it to open or close the smoke inlet 12. The moving manner of the shutter 16 includes translational sliding, rotation, and the like. That is, the motor 14 can drive the shutter 16 to slide in a translational manner, and can also drive the shutter 16 to rotate. The shielding portion 16 may be a panel or other member that can shield the smoke inlet 12. In the illustrated embodiment, the shielding portion 16 is a panel. In the following embodiments, the shielding portion 16 is used as a panel, and the motor 14 drives the shielding portion 16 to rotate.
Referring to fig. 1, a method for controlling a kitchen device according to an embodiment of the present invention includes:
step S12: controlling the motor 14 to operate to drive the shade 16 to move;
step S14: in the case where the operation period of the motor 14 and the current characteristic of the motor 14 satisfy the preset conditions, it is determined that the shielding portion 16 is moved in place.
According to the control method, the shielding part 16 is determined to move in place through comprehensive judgment of the running time of the motor 14 and the current characteristics of the motor 14, so that the influence of batch difference of the motor 14, temperature difference of a use environment and external force interference is effectively reduced, and even the problem of blocking of the shielding part 16 caused by size deviation of a transmission system is solved with probability. The solution can detect the shield 16 moving in place without a position sensor, and can reduce the cost.
Specifically, the operating time period of the motor 14 and the current characteristics of the motor 14 satisfy preset conditions including: the motor 14 is operated for a time period greater than the time period threshold, the current of the motor 14 is smoothed, and the current of the motor 14 is greater than the current threshold C0. In this manner, in the case where the operation period of the motor 14 is greater than the period threshold, the current of the motor 14 is stable, and the current of the motor 14 is greater than the current threshold C0, it can be determined that the shutter 16 is moved into position.
Further, determining that the shade 16 is moved into position includes: determining that the shield 16 is open in position or determining that the shield 16 is closed in position. Thus, the shielding part 16 is determined to be opened in place, and the effective range of the kitchen device 10 for absorbing the oil smoke is ensured; it is ensured that the shield 16 is closed in place to avoid that the electrical components inside the kitchen unit 10 are easily damaged.
It can be understood that, kitchen device 10 during operation, shielding portion 16 opens, can block the flue gas upwards to dissipate and avoid the oil smoke to inhale and remove unclean, and the contained angle that forms between shielding portion 16 and the cigarette machine body 11 can play the guide effect to the flue gas, forms great guide angle, can play the speed that delays the flue gas and rise, increases the opening angle of oil smoke import 12 for it is smooth in order to inhale the flue gas process. When the kitchen device 10 stops working, the shielding part 16 is closed, which is beneficial to shielding the smoke from flowing backwards and preventing the smoke from flowing backwards and tainting odor. Therefore, it is necessary to determine whether the shade 16 is open in place or closed in place. The movement of the shutter 16 from the open-to-position to the closed-to-position, or from the closed-to-position to the open-to-position, is usually constant, and if the motor 14 rotates at a constant speed, the operation time of the motor 14 is also constant. Therefore, the operation period of the motor 14 can be utilized as one of the judgment conditions of whether the shutter 16 is open in place or closed in place.
With the shield 16 open or closed in place, stalling of the motor 14 can occur. Referring to fig. 3, in the process of opening or closing the cooking fume inlet 12 by the shielding portion 16, the current of the motor 14 can be divided into a plurality of stages, including: s0: stationary phase of motor 14, S1: motor 14 start-up phase, S2: motor 14 operating phase, S3: imminent shutdown phase of the motor 14, S4: the motor 14 turns off the stall phase. The current is different for each phase. As can be seen from fig. 3, at the stage S4, the motor 14 is locked, so that the phase of the inside of the motor 14 cannot be changed, the current of the motor 14 does not fluctuate sharply, and the current tends to be smooth. While in other phases the current of the motor 14 fluctuates considerably. Therefore, the locked-rotor current characteristic of the motor 14 can be utilized as one of the determination conditions whether the shutter 16 is open in position or closed in position.
Specifically, the control method comprises the following steps: and determining that the current of the motor 14 is stable under the condition that the current value fluctuation range of the motor 14 is within the preset fluctuation range within the preset time period.
Therefore, the stable detection of the current of the motor 14 is realized, the method is simpler, and the efficiency is higher. Specifically, a plurality of current values (AD values) are continuously collected for a preset period of time, the difference between the maximum current value and the minimum current value is calculated (i.e., the maximum fluctuation range of the current value of the motor 14 is determined), and it is determined whether the difference is within the preset fluctuation range. If the difference is within the predetermined fluctuation range, it indicates that the current of the motor 14 is stable. In one example, the current value of the motor 14 is collected every 139us, and 250 data points may be collected continuously. The predetermined fluctuation range is, for example, 0 to 0.1A, and the predetermined fluctuation range is associated with the RC filter circuit of the current collection circuit.
Referring to fig. 4, in the stage S4, the current of the motor 14 tends to be smooth. Therefore, it is possible to determine whether the motor 14 is locked, that is, whether the shade 16 is opened in position or closed in position, by determining whether the current of the motor 14 is greater than the current threshold value C0. In one example, a batch of motors 14 is selected, and after the batch of motors 14 is placed in a high-temperature environment (the temperature is not lower than 50 ℃) for more than 2 hours, rated working voltage is applied to the motors 14 in the high-temperature environment, and the locked rotor current value of each motor 14 is recorded respectively. To ensure that the parameters can cover all of the motors 14 tested, the minimum locked-rotor current value is taken as the current threshold C0. In another example, the theoretical limit value (locked rotor current value) provided by the supplier of the motor 14 may be directly used as the current threshold value C0.
Therefore, in the present invention, whether the shutter 16 is opened in position or closed in position is determined by determining whether the operation time period of the motor 14 is greater than the time period threshold value, whether the current of the motor 14 is stable, and whether the current of the motor 14 is greater than the current threshold value C0. Therefore, the accuracy of judgment can be effectively improved through comprehensive judgment.
It should be noted that the fact that the shielding portion 16 is opened in place means that the shielding portion 16 is completely opened, and the included angle between the shielding portion 16 and the cigarette maker body 11 is the largest. The blocking portion 16 is closed in place, meaning that the blocking portion 16 is fully closed and the angle between the blocking portion 16 and the cigarette maker body 11 is substantially zero. In one example, the kitchen appliance 10 also includes a deflector 18. With the curtain 16 in the closed position, the curtain 16 and the baffle 18 lie substantially in the same plane. It will be appreciated that the deflector 18 can act to direct the flue gases. When the shielding part 16 is opened, the guide plate 18 and the shielding part 16 act together to guide the smoke to the oil smoke inlet 12, which is beneficial to absorbing the smoke.
Referring to fig. 2, the kitchen device 10 further includes a transmission hinge 13, and the motor 14 is connected to the shielding portion 16 through the transmission hinge 13. It will be appreciated that the motor 14 rotates at a faster speed and is less suitable for directly driving the shield portion 16. Therefore, the motor 14 can rotate by driving the transmission hinge 13 to rotate the shielding portion 16. The driving hinge 13 can provide support for the shielding part 16 to open or close the shielding part 16 when rotating, and can effectively limit the movable range of the shielding part 16.
Further, the cigarette maker further comprises a telescopic link 15 connecting the motor 14 and the transmission hinge 13. When the motor 14 rotates, the telescopic connecting rod 15 is driven to be telescopic so as to drive the transmission hinge 13 to rotate. In this way, the motor 14 can drive the telescopic link 15 to move telescopically in one direction through a gear, a belt or other means, and drive the transmission hinge 13 to rotate, so that the direction of the power generated by the telescopic link 15 is changed, and the opening and closing of the shielding part 16 are controlled. In the present invention, the opening and closing of the shielding portion 16 can be controlled by controlling the motor 14 to rotate forward and backward. In other embodiments, the transmission between the motor 14 and the shielding portion 16 can be realized through a gear set, a screw rod, and the like.
In some embodiments, the motor 14 is used to drive the shutter 16 to move to open the fume inlet 12, and the time duration threshold includes an open time duration threshold K1. The control method comprises the following steps: in the case where the operation period of the motor 14 is longer than the opening period threshold K1, the current of the motor 14 is smooth, and the current of the motor 14 is larger than the current threshold C0, it is determined that the shutter 16 is opened in position.
Thus, the judgment that the shielding part 16 is opened in place is accurately realized. Specifically, referring to fig. 5, the control method includes:
step S122: controlling the motor 14 to drive the shielding part 16 to move to open the lampblack inlet 12;
step S132: judging whether the running time length of the motor 14 is greater than an opening time length threshold K1, whether the current of the motor 14 is stable and whether the current of the motor 14 is greater than a current threshold C0;
step S142: in the case where the operation period of the motor 14 is longer than the opening period threshold K1, the current of the motor 14 is smooth, and the current of the motor 14 is larger than the current threshold C0, it is determined that the shutter 16 is opened in position.
Referring to fig. 6, in some embodiments, the control method includes:
step S10: after the kitchen device 10 is powered on, the motor 14 is controlled to drive the shielding part 16 to open and close for self-checking;
step S112: in the self-checking process of opening and closing the shielding portion 16, the operation time length of the motor 14 corresponding to the stroke from the closing of the shielding portion 16 to the opening of the shielding portion 16 is obtained as the opening time length threshold K1.
In this manner, the kitchen device 10 may be more closely matched to the actual application of the kitchen device 10 when it is in place. Specifically, the duration thresholds further include a default open duration threshold K01 and a default closed duration threshold K02. The default on-duration threshold K01 and the default off-duration threshold K02 are stored in advance in the kitchen appliance 10.
Referring to fig. 7 and 8, step S10 includes:
step S101: controlling the motor 14 to operate to drive the shielding part 16 to close the lampblack inlet 12;
step S102: judging whether the running time length of the motor 14 is greater than a default closing time length threshold K02, whether the current of the motor 14 is stable and whether the current of the motor 14 is greater than a current threshold C0;
step S103: under the conditions that the running time of the motor 14 is longer than a default closing time threshold K02, the current of the motor 14 is stable, and the current of the motor 14 is larger than a current threshold C0, controlling the motor 14 to run to drive the shielding part 16 to open the lampblack inlet 12;
step S104: judging whether the running time length of the motor 14 is greater than a default opening time length threshold K01, whether the current of the motor 14 is stable and whether the current of the motor 14 is greater than a current threshold C0;
step S105: under the conditions that the operation time length of the motor 14 is greater than a default opening time length threshold K01, the current of the motor 14 is stable, and the current of the motor 14 is greater than a current threshold C0, recording the operation time length of the motor 14 corresponding to the stroke from the closing of the shielding part 16 to the opening of the shielding part 16, and controlling the motor 14 to operate to drive the shielding part 16 to close the lampblack inlet 12;
step S106: judging whether the running time length of the motor 14 is greater than a default closing time length threshold K02, whether the current of the motor 14 is stable and whether the current of the motor 14 is greater than a current threshold C0;
step S107: and recording the operation time length of the motor 14 corresponding to the stroke from the opening of the shielding part 16 to the closing of the shielding part 16 to the in-place under the conditions that the operation time length of the motor 14 is greater than the default closing time length threshold K02, the current of the motor 14 is stable and the current of the motor 14 is greater than the current threshold C0.
It will be appreciated that after the kitchen unit 10 is powered on, a self-check of the opening and closing of the blanking portion 16 is first performed. Therefore, the opening duration threshold K1 for judging whether the shielding portion 16 is in place when the motor 14 is subsequently controlled to open the lampblack inlet 12 can be obtained from the process of self-opening and self-closing of the shielding portion 16. The default on-duration threshold K01 and the default off-duration threshold K02 are the default minimum on-duration for powering up the kitchen device 10, and may be obtained through a number of overall machine tests. In the present embodiment, the default open duration threshold K01 and the default close duration threshold K02 are the same. In other embodiments, the default on-duration threshold K01 and the default off-duration threshold K02 may be different.
In some embodiments, a control method comprises: with the shutter 16 open in place, the motor 14 is controlled to turn off.
Thus, reducing power consumption of the motor 14 and extending the life of the motor 14.
In some embodiments, the motor 14 is used to drive the shutter 16 to move to close the fume inlet 12, and the time duration threshold includes a closing time duration threshold K2. The control method comprises the following steps: in the case where the operation period of the motor 14 is greater than the off-period threshold K2, the current of the motor 14 is smooth, and the current of the motor 14 is greater than the current threshold C0, it is determined that the shutter 16 is closed in place.
Thus, the judgment that the shielding part 16 is closed in place is accurately realized. Specifically, referring to fig. 9, the control method includes:
step S124: controlling the motor 14 to drive the shielding part 16 to move to close the lampblack inlet 12;
step S134: judging whether the running time length of the motor 14 is greater than a closing time length threshold K2, whether the current of the motor 14 is stable and whether the current of the motor 14 is greater than a current threshold C0;
step S144: in the case where the operation period of the motor 14 is greater than the off-period threshold K2, the current of the motor 14 is smooth, and the current of the motor 14 is greater than the current threshold C0, it is determined that the shutter 16 is closed in place.

step S10: after the kitchen device 10 is powered on, the motor 14 is controlled to drive the shielding part 16 to open and close for self-checking;
step S114: in the self-checking process of opening and closing the shielding portion 16, the operation time length of the motor 14 corresponding to the stroke from the time when the shielding portion 16 is opened in place to the time when the shielding portion 16 is closed in place is obtained as the closing time length threshold K2.
In this manner, the kitchen device 10 may be more closely matched to the actual practical conditions of the kitchen device 10 when it is in place. Specifically, the duration thresholds further include a default open duration threshold K01 and a default closed duration threshold K02. The default on-duration threshold K01 and the default off-duration threshold K02 are stored in advance in the kitchen appliance 10.
Referring to fig. 7 and 8, step S10 includes:
step S101: controlling the motor 14 to operate to drive the shielding part 16 to close the lampblack inlet 12;
