Embodiment Construction

[0015] The present invention will be further described below in conjunction with accompanying drawing:

[0016] like figure 1 A washing machine washing material identification method is shown, the method includes the following steps:

[0017] (1) Put the laundry into the inner tub of the washing machine, and weigh the laundry to obtain the weight m1 of the laundry.

[0018] (2) According to the mass m1 of the laundry, inject water with a mass of m2 into the inner tub of the washing machine; at the same time, completely wet and soak the laundry.

[0019] (3) Fully stir the laundry and water in the inner tub of the washing machine to obtain a uniformly mixed mixture of laundry and water, and measure the current temperature T1 of the mixture; the uniformly mixed laundry and water, that is, the laundry is fully uniform absorb water.

[0020] (4) Use a heating device with a heating power of P to heat the mixture to increase the temperature of the mixture by ΔT, and record the he...

Abstract

The invention relates to a method for identifying material of a washing article in a washing machine. The method comprises the steps of (1) inputting the washing article into the inner drum of the washing machine, weighing the input washing article, and obtaining the weight m1 of the washing article; (2) injecting water with mass of m2 into the inner drum of the washing machine according to the mass m1 of the washing article; (3) sufficiently mixing the washing article and water in the inner drum of the washing machine, obtaining a uniformly mixed mixture of the washing article and the water, and measuring the current temperature T1 of the mixture; (4) heating the mixture by means of a heating device with a heating power P for increasing the temperature of the mixture for deltaT, and recording heating time t required for increasing the temperature of the mixture for deltaT; (5) calculating an energy amount W0 required for increasing the temperature of unit-mass mixture for a unit of temperature according to a formula W0=W / (m*deltaT); and (6) determining the material of the washing article according to the energy amount W0 which is absorbed in raising the temperature of the unit-mass mixture for a unit of temperature.

Description

technical field [0001] The invention relates to the technical field of washing machines, in particular to a method for identifying the material of laundry in a washing machine. Background technique [0002] With the rapid development of washing machine technology and the continuous improvement of users' requirements for washing machines, it is not only required that the washing machine can clean the clothes, but also that the washing machine can properly protect the clothes of different materials. At present, the existing washing machine cannot judge and identify the material of the load, which easily leads to no obvious difference in the washing process of the loads of different materials, and cannot provide good care and protection for the loads of different materials. Contents of the invention [0003] The object of the present invention is to provide a method for identifying the material of laundry in a washing machine, which can accurately identify the material of the...
