Various embodiments of the method of the present invention are presented in terms of the above-described hardware architecture.
Fig. 2 is a schematic flow chart illustrating a load determining method for a washing machine according to a first embodiment of the present invention. It should be noted that, in an implementation manner, the method provided by the present embodiment may be applied to a series drum washing machine, and it should be emphasized that the method provided by the present embodiment may also be applied to other types of washing machines, and the type of the washing machine is not limited in the present embodiment.
In an embodiment of the present invention, the method is used for a load amount judging device of a washing machine, and the method includes the steps of:
step S100, weighing a load in the washing machine to obtain a weighing result;
step S200, judging whether the loading capacity of the washing machine is full load according to the weighing result;
step S300, water is fed to a first water level frequency;
the present invention can be applied to a washing machine in which at least one sensor is provided to sense the water level frequency of the inside, which is the amount of water inside the washing machine. The more the washing machine is close to the base, the smaller the space for storing water is, the more the space is close to the top space of the washing machine is, so that the washing machine has fewer clothes in the process of sensing the quantity of clothes to be washed in the washing machine (the load quantity of the washing machine for short), the higher the sensing precision requirement is, if the water inflow is calculated through the traditional mode, namely the water replenishing time, and the water inflow is used as the mode for sensing the load quantity of the washing machine, the larger error can occur in the judgment result, and the reason is that the traditional mode is influenced by the factors such as uneven water inflow and the like. Since the higher the internal water level, the less the influence of the received inlet water, the conventional washing machine can only sense half load or full load, and cannot sense 1/4 load (or the accuracy of 1/4 load sensing is too low due to various factors). The new European standard energy efficiency standard is formally implemented at 1/10/2020, and the 1/4-load energy efficiency test is added in the new European standard energy efficiency standard, but the conventional washing machine cannot realize the sensing 1/4 load.
In this embodiment, after the laundry is put into the washing machine, the laundry in the washing machine is weighed, the weighing process can be realized by using a weighing sensor in the washing machine, a weighing result is obtained, the judgment is performed according to the weighing result, whether the loading capacity in the washing machine is full load is judged, and if the loading capacity of the washing machine is not full load, the water is controlled to enter the washing machine until the preset first water level frequency is reached. The water level can be sensed through water inlet or through an inductor in the washing machine. It should be noted that, in order to meet the new european standard, in this embodiment, the preset water level frequency is a water inlet level frequency value corresponding to 1/4 load of the washing machine.
Step S400, washing for a first preset time, and standing for a second preset time after washing;
starting the motor of the washing machine to wash, that is, starting the drum of the washing machine to wash for a first preset time to wet the load in the washing machine, and standing for a second preset time after washing, where the first preset time and the second preset time may be set according to actual conditions, for example, the first preset time is set to 4 minutes or 5 minutes, and the second preset time may be set to half minutes or 1 minute. The purpose of standing for the second preset time is to stabilize the water level in the washing machine, so that the accuracy of the detection result is ensured.
It should be noted that the washing may be performed after the water inflow is completed, or may be performed simultaneously in the process of starting the water inflow, and the difference between the two methods does not affect the final result, and only the first preset time corresponding to the two methods is different.
Step S500, detecting a second water level frequency after standing through a water level sensor, and calculating a first difference value between the second water level frequency and the first water level frequency;
and after standing for a second preset time, detecting a second water level frequency after standing through a water level sensor in the washing machine, and then calculating a difference value between the second water level frequency and the first water level frequency to be defined as a first difference value.
And step S600, determining the load of the washing machine according to the first difference value.
Then judging the size relation between the first difference value and a preset threshold value so as to determine the load capacity of the washing machine, and specifically, if the first difference value is smaller than the preset threshold value, judging the load capacity of the washing machine to be a small load capacity; and if the first difference value is greater than or equal to a preset threshold value, determining that the load of the washing machine is a large load amount. Specifically, if the preset water level frequency is the corresponding inlet water level frequency value of 1/4 loads of the washing machine, the preset threshold is the water absorption determination threshold of the washing machine 1/4 load, and is used for distinguishing 1/4 loads from non-1/4 loads. Specifically, if the first difference is less than a preset threshold, it is determined that the load amount of the washing machine is 1/4 load; if the first difference is greater than or equal to the preset threshold, it is determined that the load amount of the washing machine is not 1/4 load, which may be half load or full load.
The invention obtains a weighing result by weighing the load in the washing machine; judging whether the loading capacity of the washing machine is full load according to the weighing result; if the loading capacity of the washing machine is judged not to be full load, water is fed to the first water level frequency; washing for a first preset time, and standing for a second preset time after washing; detecting a second water level frequency after standing through a water level sensor, and calculating a first difference value between the second water level frequency and the first water level frequency; determining a load amount of the washing machine according to the first difference value. Through the mode, the load is weighed and judged, then water is fed to the first water level frequency, then the water is washed for the first preset time, the load in the washing machine is fully wetted, then the washing machine is kept still for the second preset time, the water level frequency in the washing machine is detected again after the water level in the washing machine is stable, namely the second water level frequency, then the difference value between the second water level frequency and the first horizontal frequency is calculated, and the load capacity of the washing machine is determined according to the first difference value. Compared with a mode of sensing the load of the washing machine through the water replenishing time, the method and the device are not influenced by external factors such as uneven water inflow and the like, so that the sensing result is more accurate. In addition, this application is because weighing to the load, after the load of judging washing machine, then only need carry on once wash with stew can, saved the perception time of load.

Specifically, if the second difference is smaller than a second preset threshold, the load amount of the washing machine is determined to be half load; if the second difference is greater than or equal to a second preset threshold, it is determined that the load amount of the washing machine is full.
Based on the above embodiment, the method further comprises:
