Description

Jet-flow washing machine with sealed power supply structure

technical field

The invention belongs to the technical field of household appliances, in particular to a jet-flow washing machine with a sealed power supply structure.

Background technique

At present, the washing machines produced and sold on the market mainly include drum type washing machines, pulsator type (scroll type) washing machines, stirring type or swing (leaf) type washing machines. The working principle of the pulsator washing machine is to rely on the pulsator installed at the bottom of the washing tub to rotate forward and backward to drive the clothes to turn up, down, left, and right continuously, so that the clothes, between the clothes and the wall of the barrel, are in the water Abrasion is performed, and decontamination cleaning is achieved through the action of detergents. The working principle of the drum washing machine is to use the mechanical work of the motor to rotate the drum, and the clothes are continuously lifted and dropped in the drum, and then lifted and dropped again, doing repeated movements, and the combined action of detergent and water makes the clothes clean . A stirring rod and several stirring wings in the center of the inner cylinder of the stirring or swinging (leaf) washing machine can be kept within 360° and rotate back and forth quickly or slowly according to different clothing textures, dirt degrees, and washing quality, etc. Take the clothes in your arms and rub them back and forth to remove the stains thoroughly. Therefore, the agitator washing machine has many advantages such as no winding, no wear, power saving, strong washing power, etc., and has the advantages of both the pulsator type and the drum type. The working methods of the above three kinds of washing machines are to drive the water flow through the action of the mechanical mechanism during the washing process. The clothes in the water flow will rub against the wall of the washing tub during the movement process, and the water flow velocity generated by the mechanical movement is huge, and the water flow between the clothes The friction force is strong, and the wear and tear on the clothes to be washed is relatively large, which reduces the service life of the clothes.

In addition, jet-flow or spray-type washing machines have also appeared on the market, but due to their poor sealing, the water pump often fails to be powered off, and serious situations of electric leakage and injury may occur.

Contents of the invention

In order to solve the deficiencies in the prior art, the present invention provides a jet-flow washing machine with a sealed power supply structure, which has a simple structure, reduces clothing wear, good sealing performance, and strong safety and reliability.

The upper electromagnetic induction coil cuts the magnetic induction line to generate electromagnetic induction, and the upper electromagnetic induction coil in the water tank will generate current. After being rectified by the rectifier, the alternating current will be converted into direct current to increase the electric energy for the forward rotation water pump and the reverse rotation water pump. Through this structure, the dynamic seal of the water tank is transformed into a static seal, which greatly reduces the difficulty of manufacture.

In the laundry mode, the inner cylinder must be positioned to a fixed position by the positioning block every time the inner cylinder stops, so that the upper electromagnetic induction coil on the inner cylinder and the lower electromagnetic induction coil on the outer cylinder are up and down. One-to-one alignment can improve the efficiency of power transmission. When the speed of the inner cylinder is lower than the set speed, the electromagnet is de-energized, and the positioning block pops out along the groove under the action of the spring, and is stuck in the positioning groove of the outer cylinder, so that the upper electromagnetic induction coil and the lower electromagnetic induction coil go up and down. One pair. When drying, the driving gear on the motor drives the driven gear, and the driven gear drives the inner cylinder to rotate at a high speed, thereby achieving the effect of drying the clothes. The roller plays the role of positioning the inner cylinder during high-speed rotation and prevents the inner cylinder from deflecting.

The invention has a simple structure and is easy to manufacture, provides a power supply structure based on the principle of electromagnetic induction, achieves good sealing performance, is safer and more reliable, and effectively protects clothes from wear and tear.
