Problems solved by technology

When water is injected at the same time, the space needs to be injected with a water level equal to that of the inner barrel (barrel) to make the interior work normally, and the water in this space is often not effective in the washing process, which causes a waste of water to a certain extent.

Embodiment 1

[0037] A washing machine is provided in this embodiment, comprising an inner tub 1 and an outer tub 2, such as figure 1 As shown, an inner barrel drain hole 11 is provided at the bottom of the inner barrel 1, and the inner barrel drain hole 11 is provided with a drain valve 3, and the outer barrel 2 is provided with a power device 4 that pushes a spool 31 of the drain valve 3, and the outer barrel drain hole 21, and the drain hole 21 communicates with the drain pipe 10 for draining water out of the shell 7 of the washing machine, wherein the drain hole 21 of the outer tub is located at the bottom of the outer tub 1 to discharge sewage, and the end of the drain valve 3 near the outer tub 2 is provided with a drain switch 5 and a power unit 4 The extension shaft 41 stretches out and touches the drain switch 5 to open or close the drain valve 3. Wherein the power unit 4 is a push rod motor. This structure can convert circular rotation into linear motion.

Embodiment 2

[0058] In this embodiment, the difference from Embodiment 1 is:

[0059] Such as Figure 8-9 As shown, in this embodiment, the drain valve 3 is arranged on the side wall of the inner tub 1, while the power unit is arranged on the side wall of the outer tub 2, but the inner tub drainage hole 21 that needs to be noted is still arranged at the bottom of the outer tub 2, and at the same time The bottom of the spool of the drain valve 3 is coplanar with the bottom of the inner tub 1, which can ensure that all the water in the inner tub is discharged and prevent residual washing water from remaining in the inner tub 1.

Abstract

The invention relates to a washing machine. The washing machine comprises an inner barrel and an outer barrel and is characterized in that the bottom or the lateral wall of the inner barrel is provided with an inner barrel draining hole, the inner barrel draining hole is provided with a draining valve, the outer barrel is provided with a power device for pushing the valve element of the draining valve and an outer barrel draining hole, one end, close to the outer barrel, of the draining valve is provided with a draining switch, and the extending shaft of the power device extends and touches the draining switch to open or close the draining valve. The washing machine has the advantages that when the draining valve is closed, water in the inner barrel cannot flow into the outer barrel, dirt,detergent and the like can be prevented from remaining on the barrel wall, and accordingly bacterium breeding is prevented; meanwhile, water in the inner barrel cannot flow into the outer barrel, clothes washing water use amount can be reduced effectively, and water resources can be saved; the draining valve can be opened or closed without draining valve positioning. Due to the fact that the outer barrel draining hole is arranged in the bottom of the inner barrel and the bottom of the outer barrel, water passing the draining valve accumulates at the bottom of the outer barrel and cannot filla space formed by the inner barrel and the outer barrel, and the problem of dirt accumulation can be avoided.

Description

technical field [0001] The invention relates to the technical field of household appliances, in particular to a washing machine. Background technique [0002] No matter the existing washing machine is a drum washing machine or a pulsator washing machine, a plurality of holes are provided on the inner barrel (tube). During water filling and washing, the water in the inner tub (tube) will flow into the space formed by the outer tub (tube) and the inner tub (tube) through these holes. Cannot be switched off during washing. When washing, when the washing water rotates back and forth in the space formed by the outer wall of the inner barrel (tube) and the inner wall of the outer barrel (tube), the dirt and detergent will be left on the outer wall of the inner barrel (tube) and the inner wall of the outer barrel (tube), which can be used for a long time Dirt and detergent will accumulate. Since the space formed by the outer wall of the inner barrel (barrel) and the inner wall of...
