Automatic washing machine with precise detergent putting function

Abstract

The invention discloses an automatic washing machine with a precise detergent putting function. The automatic washing machine comprises a box body, an inner washing drum in the box body, a power system and a control system, wherein a control panel and a door cover are arranged at the top of the box body, and a nozzle body is arranged at the upper part of the inner washing drum below the door cover. The automatic washing machine is characterized in that the nozzle body is a cavity, and a water outlet is arranged forwards; an openable nozzle cover is arranged at the upper part of the nozzle body, and a detergent filling port is arranged besides the nozzle body and is communicated with a liquid storage box through a liquid filling pipe; a detergent pump is also connected between the liquid storage box and the nozzle body in parallel and is controlled by the control system, and the liquid storage box is in a flat box shape and is arranged in the box body at the back of the inner washing drum below the control panel; and the height of the liquid storage box is lower than that of the detergent filling port. The automatic washing machine provided by the invention can realize multifunctional intelligent putting of various detergents, and has the advantages of safety and reliability, attractive appearance and low design difficulty.

Description

technical field [0001] The invention relates to a fully automatic washing machine, in particular to a pulsator fully automatic washing machine with precise detergent injection. Background technique [0002] A washing machine is a household appliance that uses mechanical energy to drive water to wash clothes and other fabrics. According to the rotation mode, there are fully automatic washing machines and drum washing machines with pulsator rotation. Due to the side-opening method of the drum washing machine, various detergents such as laundry detergent and softener need to be automatically added (the door cannot be opened midway to add), and the accuracy of automatic injection directly affects the laundry effect. In a typical pulsator fully automatic washing machine, since the door cover is set at the top, and the washing process can be paused and opened, the requirements for automatic addition of detergent are not high in previous products. [0003] However, with the impro...

Problems solved by technology

[0006] But the existing this washing machine also has relatively obvious defects: firstly, the detergent liquid storage box is limited by the internal space of the control panel, the capacity is small, and frequent liquid addition is required; second, the small space cannot accommodate many different detergents. The detergent liquid storage box cannot realize multi-functional automatic feeding; thirdly, even if multiple detergents are fed, each group of feeding devices needs a separate liquid outlet and a separate liquid filling port, resulting in the control panel and box. The design difficulty of the body also destroys the appearance; thirdly, the hydraulic pump or gear pump or the liquid feeding part of the gravity mechanical structure in the prior art has obvious limitations and cannot be used universally for various detergents with different physical properties. Such as too thick, watery or powdery; finally, the liquid storage box is set in the same space as the control system, which may damage the control system, and may even cause electric leakage to harm the user
