Problems solved by technology

The first detection algorithm is only applicable to washing machine models with variable frequency motors, not for washing machines with ordinary fixed frequency series motors
The second detection algorithm needs to add multiple pressure sensors to cooperate with the corresponding circuit and the whole system, which greatly increases the cost of the washing machine and the complexity of the whole system

Embodiment 1

[0048] Such as figure 1 As shown, in this embodiment, there is a washing machine weighing method. After the washing starts, the control unit judges whether the washing time reaches the set time. The weighing algorithm judges the weight of the clothes. If not, the water level is judged until the water level and washing time meet the set requirements, and then the weighing calculation is performed.

[0049] In the above scheme, there are two kinds of washing machines with automatic sensing of clothes weight. One is that the variable frequency motor detects the weight of clothes by detecting the current. The value of the value to realize the judgment of the weight of the clothes. The first detection algorithm is only applicable to washing machine models with variable frequency motors, not for washing machines with ordinary fixed frequency series motors. The second detection algorithm needs to add multiple pressure sensors to cooperate with the corresponding circuit and the comp...

Embodiment 2

[0073] Such as figure 1 As shown, in this embodiment, a washing machine weighing method includes the following steps:

[0074] S1, before washing starts, fill the water to the first set water level and record the water filling time;

[0075] S2, after the washing starts, the control unit judges whether the washing time reaches the set time,

[0076] S21, if so, carry out fuzzy judgment on the weight of the clothes according to the weighing algorithm,

[0077] S22, if not, the control unit judges whether the water level is higher than the second set water level,

[0078] S221, if so, continue washing and return to S2,

[0079] S222, if not, replenish water, record the replenishment time and return to S2;

[0080] S3, organize the data, and make a fuzzy judgment on the weight of the clothes according to the total water intake time and the water absorption rate of the clothes;

[0081] S4, adjusting the washing time according to the weight of the clothes.

[0082] In the ab...

Abstract

The invention belongs to the field of washing machines, in particular to a washing machine weighing method and a washing machine. After washing starts, a control unit judges whether or not washing time reaches set time, if yes, the weight of clothes is determined according to a preset weighing algorithm; if no, water level judgment is carried out until a water level and washing time both meet setrequirements, and then weighing calculation is performed. The washing machine weighing method has the advantages that fuzzy determination is carried out on the weight of the clothes through the weighing algorithm, a sensor and other hardware cost do not need to be additionally arranged, the washing machine weighing method also can be applied to a washing machine adopting a common series motor type, the application range is wide, and the automatic perception of the weight of the clothes is achieved through a software algorithm.

Description

technical field [0001] The invention belongs to the field of washing machines, and in particular relates to a washing machine weighing method and the washing machine. Background technique [0002] Along with the raising of people's living standard, consumer also more and more higher to the requirement of washing machine, consumer hopes that the washing time of clothes will be less, will clean again. The solution in the design stage is to increase the washing time when there are many clothes, and reduce the washing time appropriately when there are few clothes. This requires the washing machine to have the function of intelligently sensing the weight of clothes, and then adjust the washing time according to the weight of clothes , Properly increase the washing time when the clothes are heavy, and appropriately reduce the washing time when the clothes are light. [0003] At present, there are mainly two ways to solve the problem of weighing clothes, one is to use a load cell,...
