Fig. 3 shows a flowchart of a control method of a dishwasher in accordance with an embodiment of the present application.
The controller 9 is configured to execute a control method, as shown in fig. 3, which includes at least steps S310 to S370, described in detail below:
In step S310, water is introduced into the liner. Then, the process advances to step S320.
In the embodiment in which the dishwasher is provided with a water inlet valve, water is fed through the water inlet valve, the water inlet valve is controlled to be opened to feed water into the inner container in step S310.
In step S320, it is determined whether the washing water in the inner container satisfies the preset condition, and if yes, step S330 is entered.
In some embodiments, the preset condition is that the amount of the washing water in the inner container reaches the preset amount, that is, when the amount of the washing water in the inner container reaches the preset amount, the step S330 is performed.
The preset water amount can be an empirically set water inflow amount, for example, 2L, 2.5L, etc.
In an embodiment of the dishwasher provided with a water flow meter, the amount of wash water in the inner container reaching the preset amount of water may be that the water flow meter detects that the amount of wash water intake reaches the preset amount of water.
In some embodiments, the preset condition may include other conditions besides that the amount of the washing water in the inner container reaches the preset amount of water, for example, the water temperature detected by the water temperature detecting unit in the preset time satisfies the preset water temperature stability requirement, that is, when the amount of the washing water in the inner container reaches the preset amount of water and the water temperature detected by the water temperature detecting unit in the preset time satisfies the preset water temperature stability requirement, step S330 is performed.
The preset water temperature stabilization requirement may be a temperature value, which may be a value equal to zero or greater than zero, for example, 0.5 ℃. The water temperature detected by the water temperature detecting unit in the preset time meets the preset water temperature stability requirement, and the water temperature detected by the water temperature detecting unit in the preset time can be kept unchanged, or the water temperature fluctuation detected by the water temperature detecting unit in the preset time is smaller than the temperature value, for example, the difference between the maximum value and the minimum value of the water temperature detected in the preset time is smaller than the temperature value.
The preset time may be a time length value set empirically, for example, 50 seconds, 1 minute, etc. When the water temperature detected by the water temperature detecting unit in the time meets the preset water temperature stabilizing requirement, the water temperature of the washing water in the inner container is considered to be stabilized.
When the water temperature detected by the water temperature detecting unit in the preset time meets the preset water temperature stabilizing requirement, the step S330 is performed again to obtain the first water temperature detected by the water temperature detecting unit, so that the accuracy of the first water temperature can be improved, and the accuracy of the temperature rise and the power consumption obtained in the subsequent steps can be improved.
In some embodiments, the preset condition may include, in addition to the amount of the wash water in the inner container reaching the preset amount of water, other conditions, for example, the duration of the start-up operation of the wash pump reaching the preset duration, that is, when the amount of the wash water in the inner container reaches the preset amount of water and the duration of the start-up operation of the wash pump reaches the preset duration, step S330 is performed.
The preset time period can be a time period value which is set empirically, and when the time period of starting the washing pump reaches the time period value, the water temperature of the washing water in the liner generally tends to be stable. The preset time period is, for example, 1 minute, 2 minutes, or the like.
When the dish washer starts to run, the environment temperature of the inner container, the temperature of the tableware and the water temperature of the washing water in the inner container are different, after the washing pump starts to work, the spray arm starts to spray the washing water to the tableware placed in the inner container, the environment temperature of the inner container, the temperature of the tableware and the water temperature of the washing water in the inner container are gradually uniform, the water temperature of the washing water in the inner container is gradually stabilized, the starting working time of the washing pump reaches the preset time length to serve as the condition for entering the step S330 to obtain the first water temperature detected by the water temperature detecting unit, the accuracy of the first water temperature can be improved, and therefore the accuracy of the temperature rise and the power consumption obtained in the subsequent steps can be improved.
In step S330, the first water temperature detected by the water temperature detecting unit and the first electric quantity consumed by the dishwasher are obtained, and the heater is controlled to start heating. Then, the process advances to step S340.
It can be understood that the first water temperature detected by the water temperature detecting unit is the water temperature of the washing water in the inner container when the washing water in the inner container meets the preset condition.
It will be appreciated that when the dishwasher is started to operate, some of the electric loads, such as the controller, will generate electricity consumption, so it is necessary to count the first amount of electricity consumed by the dishwasher, so as to improve the accuracy of the temperature rise and electricity consumption obtained in the subsequent steps.
In step S340, it is determined whether the water temperature in the liner has risen to the second water temperature, and if so, the process proceeds to step S350.
After the heater is controlled to start heating, the water temperature of the washing water in the inner container gradually rises, the water temperature detecting unit continuously detects the water temperature of the washing water in the inner container, and when the water temperature in the inner container rises to the second water temperature, the step S350 is entered.
The second water temperature is a preset temperature value, and can be set empirically, so long as the temperature is higher than the first water temperature. Illustratively, the second water temperature is set to a higher temperature, such as 27 ℃ or 28 ℃ in summer, where the intake water temperature is higher, and is set to a lower temperature, such as 21 ℃ or 22 ℃ in winter, where the intake water temperature is lower, to avoid excessive heating time.
In step S350, the temperature rise and the power consumption of the dishwasher are obtained when the water temperature in the inner container rises from the first water temperature to the second water temperature. Then, the process advances to step S360.
In some embodiments, as shown in fig. 4, the method for obtaining the temperature rise and the power consumption consumed by the dishwasher when the water temperature in the liner rises from the first water temperature to the second water temperature includes steps S410 to S420, and is described in detail as follows:
In step S410, the second amount of electricity accumulated and consumed by the dishwasher is acquired. Then, the process advances to step S420.
In step S420, a difference between the second electric quantity and the first electric quantity is calculated, so as to obtain a temperature rise and power consumption of the dishwasher when the water temperature in the inner container rises from the first water temperature to the second water temperature.
That is, the difference between the second electric quantity and the first electric quantity is used as the temperature rise power consumption of the dish washer when the water temperature in the inner container rises from the first water temperature to the second water temperature.
In the embodiment shown in fig. 4, the second electric quantity consumed by the dishwasher is obtained, the electric quantity consumed by the dishwasher is easier to obtain, especially when the electric quantity consumed by the dishwasher is calculated by adopting a software scheme, the second electric quantity is obtained conveniently and quickly, and then the first electric quantity is subtracted from the second electric quantity, so that the temperature rise and the power consumption of the electric quantity consumed by the dishwasher when the water temperature in the liner rises from the first water temperature to the second water temperature can be obtained.
In step S360, the amount of tableware loaded in the dishwasher is determined according to the temperature rise and the power consumption. Then, the process advances to step S370.
The tableware amount of the present application is not particularly limited to the number of tableware, but is a composite concept composed of the number, mass, volume, and the like.
In some embodiments, the amount of the dishes loaded in the dishwasher is determined according to the temperature-rising power consumption amount, and the amount of the dishes loaded in the dishwasher is obtained according to the temperature-rising power consumption amount and the mapping relation between the power consumption amount and the amount of the dishes.
According to the mapping relation between the temperature rise power consumption and the tableware amount, the tableware amount loaded in the dish washer is obtained, a complex calculation process is not needed, the response speed is high, the tableware amount result can be returned immediately, the influence of external factors is small, and the tableware amount result is stable and reliable.
In the process that the water temperature in the inner container is increased from the first water temperature to the second water temperature, the temperature rise of the washing water also consumes some electric quantity, and meanwhile, the electric quantity consumed by the tableware is consumed by some electric quantity, that is, the electric quantity consumed by the temperature rise obtained in the step S350 includes the electric quantity consumed by the temperature rise of the washing water in the inner container and the electric quantity consumed by the tableware. As described above, the preset water amount is an empirically set water inflow amount, the second water temperature is a preset temperature value, and the temperature difference between the first water temperature and the second water temperature is calculated to obtain the temperature rise of the washing water, and the specific heat capacity of the washing water is known, and the water amount of the washing water is known, so that the power consumption of the temperature rise of the washing water can be obtained.

In some embodiments, the step of starting the wash pump is performed before the first water temperature detected by the water temperature detecting unit is obtained. Fig. 9 is a flowchart showing a control method of a dishwasher according to another embodiment of the present application, and as shown in fig. 9, the control method includes at least steps S910 to S980, and is described in detail as follows:
In step S910, when a washing instruction is received, water is introduced into the inner container. Then, the process advances to step S920.
In step S920, the washing pump is started to pump the washing water to the spray arm so that the spray arm sprays the washing water to the dishes placed in the tub. Then, the process advances to step S930.
In step S930, it is determined whether the washing water in the inner container satisfies the preset condition, and if yes, step S940 is performed.
In some embodiments, the preset conditions include that the amount of the washing water in the inner container reaches the preset amount of water and the duration of the start-up operation of the washing pump reaches the preset duration, that is, when the amount of the washing water in the inner container reaches the preset amount of water and the duration of the start-up operation of the washing pump reaches the preset duration, the step S940 is performed.
When the dish washer starts to run, the environment temperature of the inner container, the temperature of the tableware and the water temperature of the washing water in the inner container are different, after the washing pump starts to work, the spray arm starts to spray the washing water to the tableware placed in the inner container, the environment temperature of the inner container, the temperature of the tableware and the water temperature of the washing water in the inner container are gradually uniform, the water temperature of the washing water in the inner container is gradually stabilized, the time length of the starting work of the washing pump reaches the preset time length as the condition of entering the step S940 to obtain the first water temperature detected by the water temperature detecting unit, the accuracy of the first water temperature can be improved, and therefore the accuracy of the temperature rise and the power consumption obtained in the subsequent steps can be improved.
The preset time period can be a time period value which is set empirically, and when the time period of starting the washing pump reaches the time period value, the water temperature of the washing water in the liner generally tends to be stable. The preset time period is, for example, 1 minute, 2 minutes, or the like.
In step S940, the first water temperature detected by the water temperature detecting unit and the first electric quantity consumed by the dishwasher are obtained, and the heater is controlled to start heating. Then, the process advances to step S950.
It can be understood that the first water temperature detected by the water temperature detecting unit is the water temperature of the washing water in the inner container when the washing water in the inner container meets the preset condition.
In some embodiments, obtaining the first electric quantity consumed by the dishwasher in a cumulative way comprises reading the rated power of the stored washing pump and the rated power of the controller, and determining the first electric quantity consumed by the dishwasher in a cumulative way according to the rated power and the working time of the washing pump and the rated power of the controller. Specifically, the rated power of the washing pump and the working time of the washing pump are multiplied to obtain the electric quantity consumed by the washing pump, the rated power of the controller and the working time of the washing pump are multiplied to obtain the electric quantity consumed by the controller, and then the electric quantity consumed by the washing pump and the electric quantity consumed by the controller are added to obtain the first electric quantity consumed by the accumulated dishwasher.
In step S950, it is determined whether the water temperature in the liner has risen to the second water temperature, and if so, the process proceeds to step S960.
In step S960, the temperature rise and the power consumption of the dishwasher are obtained when the water temperature in the inner container rises from the first water temperature to the second water temperature. Then, the process advances to step S970.
In some embodiments, obtaining the power consumption of the temperature rise consumed by the dishwasher when the water temperature in the inner container rises from the first water temperature to the second water temperature comprises obtaining the second power consumption accumulated by the dishwasher, calculating the power difference between the second power consumption and the first power consumption, and obtaining the power consumption of the temperature rise consumed by the dishwasher when the water temperature in the inner container rises from the first water temperature to the second water temperature.
In some embodiments, obtaining the second power accumulated and consumed by the dishwasher comprises reading the rated power of the stored washing pump, the controller and the heater, and determining the second power accumulated and consumed by the dishwasher according to the rated power and the working time of the washing pump, the controller and the heater. Specifically, the rated power of the washing pump and the working time length are multiplied to obtain the electric quantity consumed by the washing pump, the rated power of the controller and the working time length are multiplied to obtain the electric quantity consumed by the controller, the rated power of the heater and the working time length are multiplied to obtain the electric quantity consumed by the heater, and then the electric quantity consumed by the washing pump, the electric quantity consumed by the controller and the electric quantity consumed by the heater are added to obtain the second electric quantity consumed by the accumulated dishwasher.
In step S970, the amount of tableware loaded in the dishwasher is determined according to the temperature-rising power consumption. Then, the process advances to step S980.
In an exemplary embodiment, the preset water amount is 2.75L, the first temperature is 21 two, the second temperature is 26 two, and the corresponding relationship between the temperature rise, the power consumption and the tableware amount shift is shown in fig. 10.
In step S980, a washing parameter of the dishwasher is determined according to the quantity of dishes.
In the embodiment shown in fig. 9, starting the washing pump to pump the washing water to the spray arm can make the spray arm spray the washing water to the tableware placed in the inner container, so that the environment temperature of the inner container, the temperature of the tableware and the water temperature of the washing water in the inner container are gradually uniform, the water temperature of the washing water in the inner container is gradually stabilized, and the time length of starting the washing pump reaches the preset time length to be used as the condition for entering the step S940 to obtain the first water temperature detected by the water temperature detecting unit, so that the accuracy of the first water temperature can be improved, and the accuracy of the power consumption of the temperature rise obtained in the subsequent steps can be improved.
Of course, in some embodiments, the accuracy of the first water temperature may also be improved by detecting other parameters, for example, detecting the water inlet temperature of the liner and the liner ambient temperature, and correcting the first water temperature according to the water inlet temperature and the liner ambient temperature.
It can be understood that after the washing pump is started, the washing pump can be kept in a starting state all the time, so that the water temperature of the washing water can be uniform while the washing pump is heated after the heater is controlled to start heating, thereby accurately judging whether the water temperature in the inner container rises to the second water temperature or not and saving the subsequent washing time. Also, after the heater is controlled to start heating, the heater may be maintained in a start state until the water temperature in the inner tub rises to a target washing temperature, which may be determined based on the calculated amount of dishes, to avoid starting and stopping the heater a plurality of times.

Accordingly, the scope of the application is limited only by the attached claims.
