The hot air power may be set to be linearly adjustable or stepwise adjustable, for example, the hot air power may be set to be linearly adjustable between 0% and 100% of the rated hot air power, or the hot air power may be set to be stepwise adjustable in at least two steps between 0% and 100% of the rated hot air power.
As shown in fig. 2, in an embodiment, based on the embodiment corresponding to fig. 1, step S102 includes:
step S201, when the hot air power adjusting instruction is detected, determining a hot air power gear corresponding to the hot air power adjusting instruction;
and S202, adjusting the hot air power of the heating device and the fan to be the size corresponding to the hot air power gear.
In application, the number of hot air power gears and the hot air power of the heating device and the fan at each hot air power gear can be set according to actual needs. The number of hot wind power steps may be set to any value greater than or equal to 2. For example, 3 hot air power gears of strong force, standard and energy saving can be set, and the hot air power of the heating device and the fan at each hot air power gear is 100%, 83% and 66% of rated hot air power respectively. The first corresponding relation between different hot air power adjusting instructions and hot air power gears can be pre-established and stored, so that when the hot air power gears need to be adjusted, the hot air power gears corresponding to the hot air power adjusting instructions can be quickly determined according to the hot air power adjusting instructions and the first corresponding relation. The first corresponding relationship may exist in the form of a first corresponding relationship Table, and the first corresponding relationship Table may specifically be a Look-Up Table (LUT), and may also exist in the form of a corresponding lookup result that can be searched and output through other input data.
In application, after the hot air power gear is determined according to the hot air power adjusting instruction, the hot air power is adjusted to be the size corresponding to the hot air power gear according to the hot air power corresponding to the hot air power gear. The second corresponding relation between different hot air power gears and the hot air power can be pre-established and stored, so that when the hot air power needs to be adjusted, the hot air power corresponding to the hot air power gear can be quickly determined according to the hot air power gears and the second corresponding relation. The second corresponding relationship may exist in the form of a second corresponding relationship table, which may specifically be a display lookup table, or may exist in the form of a corresponding lookup result that can be looked up and output through other input data.
As shown in fig. 3, an exemplary table showing the correspondence between the hot wind power gear, the hot wind power percentage (i.e. the ratio of the hot wind power to the rated hot wind power × 100%), and the hot wind power is shown; the hot air power gears comprise three hot air power gears of strong force, standard force and energy saving, the hot air power percentage comprises 100%, 83% and 66% corresponding to the three hot air power gears, and the hot air power comprises 280W (watt), 232W and 185W corresponding to the three hot air power gears.
As shown in fig. 4, in an embodiment, based on the embodiment corresponding to fig. 2, the method for adjusting hot air power includes:
step S101, detecting a hot air power adjusting instruction input by a user;
step S201, when the hot air power adjusting instruction is detected, determining a hot air power gear corresponding to the hot air power adjusting instruction;
step S401, detecting a capacity selection instruction input by a user;
step S402, when the capacity selection command is detected, determining the capacity corresponding to the capacity selection command;
and S403, adjusting the hot air power of the heating device and the fan to be the hot air power corresponding to the hot air power gear and the capacity.
In application, for the dishwasher with the selectable capacity, a user can input a capacity selection instruction through any human-computer interaction mode supported by the dishwasher before or after inputting a hot air power regulation instruction, or sends the capacity selection instruction to the dishwasher through any human-computer interaction mode supported by the terminal device so as to select the capacity of the dishwasher. If the user does not select the capacity, the hot air power is adjusted only according to the hot air power gear by default; when the dishwasher is started, the dishwasher can work under the capacity selected by the user last time by default, the user can switch the capacity according to the actual requirement, and if the user does not switch the capacity, the dishwasher is determined to work under the capacity selected by the user last time by default. The third corresponding relation between different capacity selection instructions and the capacity can be pre-established and stored, so that when the capacity needs to be selected, the capacity corresponding to the capacity selection instruction can be quickly determined according to the capacity selection instruction and the third corresponding relation. The third corresponding relationship may exist in the form of a third corresponding relationship table, and the third corresponding relationship table may specifically be a display lookup table, or may exist in the form of a corresponding lookup result that can be looked up and output through other input data. Step S403 is a further definition and refinement of step S202.
In application, when the dishwasher is at the same hot air power gear, the hot air power of the dishwasher is different under different capacities. Specifically, when the dishwasher is in the same hot air power gear, the hot air power of the dishwasher under a large capacity is larger than that under a small capacity.
As shown in fig. 5, a table of the corresponding relationship between the hot air power gear, the hot air power percentage and the hot air power at different capacities is exemplarily shown; the hot air power gears comprise three hot air power gears with strong force, standard performance and energy saving performance, the hot air power percentage comprises 100%, 83% and 66% corresponding to the three hot air power gears, the capacity comprises 12 sets or more and 8 sets of two types, the hot air power corresponding to the three hot air power gears and 12 sets or more comprises 280W, 232W and 185W, and the hot air power corresponding to the three hot air power gears and 8 sets of capacity comprises 230W, 191W and 152W.
In one embodiment, step S401 includes:
detecting a capacity selection instruction input by a user in a touch control mode, a gesture control mode or a voice control mode;
alternatively, a capacity selection instruction sent by a user through a terminal device in communication with the dishwasher is detected.
As shown in fig. 6, in one embodiment, based on the corresponding embodiment described in fig. 1, step S101 includes:
step S601, when the hot air power regulation mode is a non-automatic mode, detecting a hot air power regulation instruction input by a user;
the hot air power adjusting method further comprises the following steps:
step S602, when the hot air power adjusting mode is the automatic mode, detecting the weight of the bowl basket;
and S603, adjusting the hot air power of the heating device and the fan to be the size corresponding to the weight of the bowl basket.
In application, the dishwasher supports two hot air power adjusting modes for adjusting the hot air power, wherein the first mode is a non-automatic mode, and the second mode is an automatic mode. When the non-automatic mode is started, the user can correspondingly adjust the hot air power to the required size according to actual needs through any human-computer interaction mode supported by the dish washing machine or through inputting different hot air power adjusting instructions by the terminal equipment. When the automatic mode is started, the weight of the bowl basket can be detected by a weight sensor arranged on the dish washing machine, and then the hot air power is automatically adjusted to the size corresponding to the weight of the bowl basket according to the weight of the bowl basket.
In application, the lower surface of each bowl basket of the dishwasher or the positions at the two ends of the bowl basket for supporting the bowl baskets can be provided with weight sensors which correspond to the bowl baskets and are electrically connected with the processor for respectively sensing the weight of the bowl baskets. When tableware is arranged in the bowl basket, the weight of the bowl basket refers to the total weight of the bowl basket and the tableware in the bowl basket; when no tableware is in the bowl basket, the weight of the bowl basket is the weight of the bowl basket.
As shown in fig. 6, in one embodiment, before steps S601 and S602, the method includes:
step S604, detecting a mode selection instruction;
and step S605, when the mode selection instruction is detected, selecting a hot air power adjustment mode corresponding to the mode selection instruction.
In the application, a user can input a mode selection instruction through any human-computer interaction mode supported by the dishwasher at any time when using the dishwasher, or send the mode selection instruction to the dishwasher through any human-computer interaction mode supported by the terminal equipment so as to select a hot air power regulation mode. When the dishwasher is started, the dishwasher can work in an automatic mode, a non-automatic mode or a hot air power adjusting mode selected by a user last time by default. The user can switch the hot air power regulation mode according to actual needs. The fourth corresponding relation between different mode selection instructions and the hot air power regulation modes can be pre-established and stored, so that when the hot air power regulation mode needs to be selected, the hot air power regulation mode corresponding to the mode selection instruction can be quickly determined according to the mode selection instruction and the fourth corresponding relation. The fourth corresponding relationship may exist in the form of a fourth corresponding relationship table, and the fourth corresponding relationship table may specifically be a display lookup table, or may exist in the form of a corresponding lookup result that can be looked up and output through other input data.
In one embodiment, step S604 includes:
detecting a mode selection instruction input by a user in a touch control mode, a gesture control mode or a voice control mode;
alternatively, a mode selection instruction sent by a user through a terminal device in communication connection with the dishwasher is detected.
As shown in fig. 7, in one embodiment, step S603 includes:
s701, determining a hot air power gear corresponding to the weight of the bowl basket;
and S702, adjusting the hot air power of the heating device and the fan to be the size corresponding to the hot air power gear.
In application, the fifth corresponding relation between the weight of different bowl baskets and the hot air power gear can be pre-established and stored, so that when the hot air power gear needs to be adjusted, the hot air power gear corresponding to the weight of the bowl basket can be quickly determined according to the weight of the bowl basket and the first corresponding relation. The fifth corresponding relationship may exist in the form of a fifth corresponding relationship table, and the fifth corresponding relationship table may specifically be a display lookup table, or may exist in the form of a corresponding lookup result that can be looked up and output through other input data. After the hot air power gear is determined according to the weight of the bowl basket, the hot air power is adjusted to be the size corresponding to the hot air power gear according to the hot air power corresponding to the hot air power gear.

In one embodiment, the dishwasher further comprises a thyristor drive circuit electrically connected to the heating device and the fan, the thyristor drive circuit comprising a triac.
As shown in fig. 9, an exemplary thyristor driving circuit 9 is shown, which includes a first optical coupler OC1, a triac TR1, a first resistor R1, a second resistor R2, a third resistor R3, a fourth resistor R4, and a capacitor C1;
a first input end of the first optical coupler OC1 is electrically connected with a power supply VDD and a processor IC1 through a first resistor R1, a second input end of the first optical coupler OC1 is electrically connected with the processor 100, a first output end of the first optical coupler OC1 is electrically connected with a control electrode of the bidirectional thyristor TR1 and one end of a second resistor R2, and a second output end of the first optical coupler OC1 is electrically connected with one end of a third resistor R3;
the other end of the second resistor R2, one end of the capacitor C1 and a first electrode of the bidirectional thyristor TR1 are electrically connected with a zero line of the alternating current power supply AC, the other end of the capacitor C2, the other end of the third resistor R3 and a second electrode of the bidirectional thyristor TR1 are electrically connected with one end of the heating plate 200 and one end of the fan 300, and the other end of the heating plate 200 and the other end of the fan 300 are electrically connected with a live line of the alternating current power supply AC.
In application, the heating tube and the fan are controlled by the silicon controlled driving circuit. The alternating current power supply can be a 220V commercial power alternating current power supply and is used for outputting alternating current signals. The bidirectional controllable silicon is a key device for controlling the on and off of the electric connection between the alternating current power supply and the heating tube and between the alternating current power supply and the fan. The optocoupler is used for driving the bidirectional thyristor to be switched on or switched off under the control of the processor, has a strong and weak current isolation effect and ensures the safety and reliability of the thyristor driving circuit. The optocoupler also has a zero crossing point detection function of an alternating current power supply, and ensures that the output end of the optocoupler can be switched on and controls the bidirectional thyristor to be switched on only when the zero crossing point of the alternating current power supply is reached, so that the current when the bidirectional thyristor is switched on is gradually increased from 0, and the bidirectional thyristor is prevented from being damaged by current mutation when the bidirectional thyristor is switched on. The first resistor is a pull-up resistor and is used for providing a working power supply at the input end of the optical coupler and limiting the current of the working power supply not to exceed a limit value. The second resistor is used for improving the immunity of the silicon controlled drive circuit to surge current and fast transient pulse. The third resistor and the fourth resistor are gate resistors for limiting the gate current to not exceed a limit value. The capacitor and the fourth resistor increase the immunity of the gate circuit to surge currents and fast transient pulses.
As shown in fig. 10, an exemplary thyristor driving circuit 10 is shown, which further includes an ac zero crossing detection circuit 11 on the basis of the thyristor driving circuit 9 shown in fig. 9, where the ac zero crossing detection circuit 11 includes a second optical coupler OC2, a first diode D1, a second diode D2, and a fifth resistor R5;
the first output end of the second optical coupler OC2 is grounded and is electrically connected with the processor 100, the second output end of the second optical coupler OC2 is electrically connected with the processor 100, the first input end of the second optical coupler OC2 is electrically connected with the cathode of the first diode D1 and the cathode of the second diode D2, the second input end of the second optical coupler OC2 is electrically connected with the anode of the second diode D2 and the live wire of the alternating current power supply AC, and the anode of the first diode D1 is electrically connected with the zero wire of the alternating current power supply AC through the fifth resistor R5.
In application, the operating principles of the devices with the same reference numbers in the thyristor driving circuits shown in fig. 9 and 10 are the same, and are not described herein again. The processor can filter the waveform of the alternating current signal to form a square wave signal synchronous with the alternating current signal by judging the rising edge and the falling edge of the zero crossing point of the alternating current signal detected by the alternating current zero crossing point detection circuit, then the processor outputs a trigger signal to control the conduction angle or the switching time of the bidirectional thyristor, the square wave signal can be filtered to be a required driving signal, and the driving signal is used for being output to the heating tube and the fan so as to drive the heating tube and the fan to work under corresponding hot air power.
As shown in fig. 11, a waveform diagram of an alternating current signal 1 and a square wave signal 2 is exemplarily shown; wherein, the horizontal axis coordinate is time t, and the vertical axis coordinate is voltage V.
In one embodiment, step S202 or step S702 includes:
determining a trigger signal matched with the hot air power gear according to the hot air power gear;
controlling the on-off time or the conduction angle of the bidirectional controllable silicon according to the trigger signal so as to adjust the hot air power of the heating device and the fan to be in a size corresponding to the hot air power gear;
wherein, the on-off time includes the on-time and the off-time of bidirectional thyristor in a cycle of trigger signal, the ratio of on-time and off-time with hot air power gear and hot air power positive correlation, the conduction angle with hot air power gear and hot air power negative correlation.
In application, the types of the trigger signals are different according to different structures of the silicon controlled drive circuit. When the thyristor drive circuit is composed of the optocoupler, the triac and peripheral devices thereof, and does not include an ac zero crossing detection circuit (e.g., the thyristor drive circuit 9 shown in fig. 9), the trigger signal may specifically be a pulse signal based on a wave loss control manner. When the thyristor drive circuit is composed of an optocoupler, a triac, an ac zero-crossing detection circuit, and peripheral devices thereof (e.g., the thyristor drive circuit 10 shown in fig. 10), the trigger signal may specifically be a pulse signal based on a wave loss or chopping control manner.
In application, the wave-dropping control mode refers to controlling the switching time of the bidirectional controllable silicon in one period of the trigger signal. The ratio of the conduction time in the switching time is equal to the percentage of the hot air power. For example, assuming that one cycle time of the trigger signal is 6S (seconds), when the on time and the off time are 6S and 0S, respectively, the hot air power percentage is 6S/6S — 100%; when the on-time and the off-time are respectively 5S and 1S, the hot air power percentage is 83% in 5S/6S; when the on time and the off time are respectively 4S and 2S, the hot air power percentage is 66% for 4S/6S.
In application, the chopping control mode is to control the conduction angle of the bidirectional thyristor, that is, in the process of supplying power to the heating device and the fan through the alternating current signal, the output of the alternating current signal is cut off at a certain phase of the alternating current signal, and the phase angle of the phase in the sine waveform of the alternating current signal is the conduction angle.
As shown in fig. 12, a schematic waveform diagram exemplarily showing an alternating current signal 1 and three conduction angles θ 1, θ 2, and θ 3 when a heating device and a fan are driven by the thyristor drive circuit 9 shown in fig. 9 in a chopper control manner; the horizontal axis coordinate is time t, the vertical axis coordinate is voltage V, and the three conduction angles theta 1, theta 2 and theta 3 respectively correspond to the power, the standard and the energy conservation of the hot air power gear.
As shown in fig. 13, a schematic waveform diagram exemplarily showing an ac signal 1, a trigger signal 3, and a driving signal 4 output to a heating device and a fan when the heating device and the fan are driven by the thyristor driving circuit 10 shown in fig. 10 in a lost wave control manner; wherein, the horizontal axis coordinate is time t, and the vertical axis coordinate is voltage V.
