The invention relates to the field of washing machine component control and concretely relates to a washing machine detergent automatic casting device and a control method for the same. The washing machine detergent automatic casting device comprises a storage box, a detergent box, a conduit, a conveying pump, a washing machine inner barrel, a micro-processor and a first weighing sensor mounted on the bottom of the detergent box, wherein the detergent box is placed in the storage box; an outlet of the conveying pump is communicated with a first liquid inlet of a mixing box via the conduit; the mixing box is further provided with a second liquid inlet; the second liquid inlet is communicated with external tap water; an outlet of the mixing box is connected with the washing machine inner barrel; a second weighing sensor is further arranged on the bottom of the inner barrel of the washing machine; the first weighing sensor and the second weighing sensor are respectively connected with the micro-processor; and the micro-processor controls the conveying pump to work. The detergent box is simply structured, can be easily taken out and precisely cast; tap water and the detergent can be mixed and stirred via spiral blades in the mixing box, so washing effect can be enhanced.
Description
technical field [0001] The invention relates to the field of washing machine component control, in particular to a washing machine detergent automatic dispensing device and a control method thereof. Background technique [0002] At present, most of the automatic dispensing devices for washing machines are equipped with detergent storage boxes to store detergents. However, when detergents are stored in the detergent boxes for a long time, they are prone to air-drying and solidification, and the residues in the boxes affect the liquid level detection and use of detergents. Performance, so it is important to find a device that facilitates cleanup and long-term storage of detergent. [0003] The amount of detergent used in common washing machines is mainly controlled by the timing of the quantitative container and the delivery pump. However, this method of controlling the amount does not guarantee the accuracy of the dosage. Contents of the invention [0004] Aiming at the pr...
