Problems solved by technology

But long-term operation, because the sealing structure is worn for a long time, it is easy to cause wear and leakage. If the water quality is poor and the sand content is high, the service life will be greatly shortened, and it will not be able to perform its due function.
It is also not suitable for use in the state of large washing capacity, and the reliability is poor

Embodiment 1

[0049] Such as Figure 2-6 As shown, the locking mechanism of the present invention at least includes a locking lever 302 that can reciprocate in the axial direction, a slideway for the locking lever to move and a drive unit that drives the locking lever to move, and the locking lever 302 extends Enter the locking hole 301, the inner barrel 100 is locked, the locking rod 302 escapes from the locking hole 301, and the inner barrel 100 is unlocked.

[0050] The locking mechanism also includes a fixing base 303 of a locking rod 302, the center of the fixing base 303 is provided with a slideway 304, and the locking rod 302 passes through the sliding way 304, preferably the fixing base 303 It is a ring structure, and the center of the fixing seat 303 is bent upwards or downwards to form the slideway 304 .

[0051] The locking mechanism also includes a fixed shell 305, the fixed shell 305 is installed on the top of the fixed seat 303, fixedly connected with the fixed seat 303, can ...

Embodiment 2

[0080] Such as Figure 7-12 As shown, in the drainage control mechanism of the inner bucket in the present invention, the bottom of the inner bucket is provided with a drainage port, and the drainage control mechanism includes at least one retractable valve plug, and the valve plug moves upward to close the drainage port, and the valve plug moves toward The downward movement opens the drain port, and the valve plug is fixed in the circumferential direction. When the valve plug moves upward and seals the drain port 105, the control drain port 105 is closed. When the valve plug moves downward and escapes from the drain port 105, the control The drain port 105 is open. The drainage control mechanism also includes a crank connecting rod structure, the lower end of the valve plug is connected to the connecting rod of the crank connecting rod structure. When the drainage control mechanism receives an error signal, the valve plug extends, but does not extend into the drain port. At ...

Embodiment 3

[0103] Such as Figure 13 As shown, a control method of a water-saving washing machine in the present invention, the bottom of the inner tub of the washing machine is provided with a locking hole and a drain, and the bottom of the outer tub of the washing machine is provided with a locking mechanism and a drainage control mechanism. The steps are as follows:

[0104] Step 1: Enter the washing / rinsing program, the main control board controls the locking mechanism and the locking hole to lock the inner tub, the drainage control mechanism blocks the drain, the water inlet valve enters the inner tub to the set water level or water volume, and starts washing. There is no water between the inner barrel and the outer barrel.

[0105] After receiving the washing / rinsing signal, the main control board sends the inner tub lock command, drives the inner tub to rotate so that the locking hole corresponds to the position of the locking lever, and the locking lever of the control locking me...

Abstract

The invention relates to a locking mechanism of an inner tub and a washing machine. The locking mechanism includes a locking lever capable of reciprocating axial movement, a slideway for the locking lever to move, and a drive unit for driving the locking lever to move. The feature is that the locking mechanism further includes a position switch, and a trigger structure of the position switch is set on the locking lever. When the locking rod extends into the locking hole and locks in place, the trigger structure triggers the position switch, and the position switch sends out a signal of locking in place. When the locking rod retracts out of the locking hole and retracts to reset, the trigger structure triggers the position The switch sends out a signal of unlocking in place, so that the main control board of the washing machine can control the washing machine to carry out the next procedure. The position of the locking rod is used to accurately judge whether the locking rod is locked or unlocked in place, and the judgment is accurate and the structure is simple.

Description

technical field [0001] The invention relates to the field of washing machines, in particular to a locking mechanism for an inner tub and a washing machine. Background technique [0002] In the existing pulsator type washing machine, there is a permeable hole in the inner barrel, and the inner and outer barrels are connected. The water that participates in washing is only the part in the inner tub, which leads to greater waste of water resources. In addition, too much water between the inner and outer tubs will also reduce the concentration of detergent / washing powder in the washing liquid. At the same time, due to the frequent flow of water in and out between the inner barrel and the outer barrel, after continuous use, the area between the side walls of the inner barrel and the outer barrel has also become a space for dirt. The cellulose of clothes, the organic matter of the human body and the dust and bacteria brought in by the clothes are very likely to stay between the s...
