Embodiment 1

[0055] A method for automatically adding detergent to a washing machine, wherein the flow coefficient of the fluid entering the washing tub by the automatic feeding device is detected and compared with the set value of the flow coefficient, and if the detected value does not match the set value, the automatic feeding device is judged. If the detergent inside is insufficient, an alarm will be issued and automatic delivery will be stopped.

[0056] When the user selects the automatic dispensing function, if the washing machine judges that the detected flow coefficient is consistent with the set air flow coefficient, it is determined that there is no detergent in the automatic dispensing device, an alarm is issued, and the automatic dispensing function is not run.

[0057]The automatic feeding runs for a certain period of time, and the flow coefficient of the fluid in this period is detected. If the flow coefficient changes, it is determined that the detergent in the automatic fee...

Embodiment 2

[0093] A method for automatically injecting detergent into a washing machine, the washing machine includes an automatic injecting device with a flow sensor inside, calculating the amount of detergent to be dispensed according to washing needs and controlling the injecting water, the method is based on the flow coefficient of the fluid detected by the flow sensor. , judge whether the detergent in the automatic feeding device is insufficient, if so, it will issue an alarm and stop the automatic feeding.

[0094] For a washing machine of a certain structure, the entire circuit of the water inlet valve, the water inlet pipe and the automatic delivery device of the washing machine is determined. When the liquid to be delivered in the automatic delivery device is constant, there is a certain relationship between the flow rate of the fluid and the pressure, that is, the flow coefficient , the flow pipeline is certain, and the flow coefficient can reflect the viscosity of the fluid.

Embodiment 3

[0136] A method for automatically injecting detergent into a washing machine, the washing machine includes an automatic injecting device with a flow sensor inside, the amount of detergent is calculated according to washing needs and the injection of water is controlled, and the method is based on the flow coefficient of the fluid detected by the flow sensor. , judge whether the detergent in the automatic feeding device is insufficient, if so, it will issue an alarm and stop the automatic feeding.

[0137] For a washing machine of a certain structure, the entire circuit of the water inlet valve, the water inlet pipe and the automatic delivery device of the washing machine is determined. When the liquid to be delivered in the automatic delivery device is constant, there is a certain relationship between the flow rate of the fluid and the pressure, that is, the flow coefficient , the flow pipeline is certain, and the flow coefficient can reflect the viscosity of the fluid.

Abstract

The invention belongs to the technical field of washing machines, and in particular relates to a method for automatically feeding detergent into a washing machine and the washing machine. The method for automatically injecting detergent into the washing machine is as follows: detecting the flow coefficient of the fluid entering the washing tub from the automatic injecting device and comparing it with the set value of the flow coefficient; If the detergent is insufficient, an alarm will be issued and automatic feeding will be stopped. The method for automatically adding detergent to a washing machine according to the present invention is applicable to accurate and automatic adding of detergent to a washing machine without a flow sensor provided with a steel needle, which is simple and reliable, and has low operating costs.

Description

technical field [0001] The invention belongs to the technical field of washing machines, and in particular relates to a method for automatically putting detergent in a washing machine and a washing machine. Background technique [0002] At present, various washing machine manufacturers have launched washing machines with automatic dispensing function. This washing machine can realize the intelligent addition of detergents, avoid users manually adding detergents, and is more convenient and user-friendly. [0003] The washing machine with automatic feeding function can intelligently detect parameters such as water quality and the degree of soiling of clothes, and calculate the precise dose of detergent. Among them, some washing machines with automatic feeding function use fuzzy weighing to judge the weight of the clothes, determine the water consumption corresponding to the amount of clothes, and then control the working time of the feeding pump according to the fixed ratio of...
