Embodiment 1

[0050] Such as figure 1 and figure 2 As shown, a washing machine is introduced in this embodiment. A sealed inner cylinder 1 is installed in the washing machine shell 2. The inner cylinder 1 is connected to the water inlet of the washing machine through the water inlet pipe 17. The water inlet pipe 17 is provided with a constant volume box. 40. When the water level in the constant volume box 40 reaches a high water level, the water inlet of the constant volume box 40 is closed and the water outlet is opened, and water enters the inner cylinder 1; when the water level in the constant volume box 40 reaches a low water level, the The water inlet is opened and the water outlet is closed; the corresponding water level of the inner cylinder is obtained by detecting the number of openings of the water outlet of the constant volume box 40 .

[0051] Such as figure 1 As shown, in the present embodiment, the fixed volume box 40 is provided with a water inlet and a water outlet, and t...

Embodiment 2

[0059] This embodiment introduces a control method for a washing machine. The water source of the washing machine flows into the constant volume box. By controlling the valve body set in the constant volume box, the water in the constant volume box is stored to a high water level, and then the water is stored in the constant volume box. The water is discharged into the inner cylinder until the water level of the fixed volume box reaches the low water level, and the number of times of drainage of the fixed volume box is counted to obtain the water inlet water level of the inner cylinder of the washing machine.

[0060] In this embodiment, the specific steps of the washing machine control method are as follows,

[0061] Step 1. Enter water from the washing machine water inlet pipe into the inner tub of the washing machine;

[0062] Step 2. Open the water inlet of the constant volume box, close the water outlet, and the water of the washing machine flows into the constant volume ...

Embodiment 3

[0072] In this embodiment, in order to realize the sealing at the mouth 101 of the inner cylinder when the washing machine is working, the following settings are made:

[0073] Such as figure 1 and figure 2 As shown, a washing machine, a door cover 4 is installed on the washing machine shell 2, and the door cover 4 is relatively rotatably connected with the inner cylinder cover 8 through the elastic mechanism, so that the elastic mechanism provides the inner cylinder cover 8 with the door cover 4 closed. The locking elastic force makes the inner cylinder cover 8 and the inner cylinder mouth 101 in sealing contact, and makes the inner cylinder cover 8 rotate together with the inner cylinder 1, so that the inner cylinder cover 8 is fastened to the inner cylinder mouth 101 after the door cover 4 is closed. The purpose of inner cylinder 1 sealing.

[0074]Through the above settings, the inner cylinder cover at the mouth of the inner cylinder is sealed by elastic force. During t...

Abstract

The invention relates to a washing machine and a control method. A sealed inner tub is installed inside a washing machine shell. The inner tub is communicated with a water inlet source of the washingmachine through a water inlet tube, a constant volume box is arranged on a water inlet tube, when the water level inside the constant volume box reaches a high water level, a water inlet is closed, awater outlet is opened, water flows into the inner tub; when the water level inside the constant volume box reaches the low water level, the water inlet is opened, and the water outlet is closed; thecorresponding water level of the inner tub is obtained by detecting the opening frequency of the water outlet of the constant volume box. According to the device and method, the constant volume box isarranged on the water inlet pipe of the washing machine, water is drained to the inner tub after water is stored in the constant volume box, the drainage frequency of the constant volume box is detected, and the precise water level in the inner tub of the washing machine can be obtained; meanwhile, a water level detecting device of the washing machine is arranged on the water inlet pipe of the inner tub, and the washing machine with the dual functions of inner tub rotation and water containing can work normally; in addition, the inner tub does not need to be sleeved with an outer tub, the volume of the inner tub is increased, and the washing capacity of the washing machine is improved.

Description

technical field [0001] The invention belongs to the technical field of washing machines, and in particular relates to a washing machine with only a rotatable and water-holding inner cylinder, in particular to a water inlet and / or heating structure of the washing machine, and also to a control method of the washing machine. Background technique [0002] In the prior art, a drum washing machine generally includes an inner cylinder and an outer cylinder that fit each other, the outer cylinder is sealed to hold water, the inner cylinder is used to hold clothes, and the inner cylinder is rotated to beat and wash the clothes; at the same time, the inner cylinder is Set the dehydration hole so that the water in the outer cylinder flows into the inner cylinder through the dehydration hole to soak the clothes in the inner cylinder, the water in the inner cylinder flows out to the outer cylinder through the dehydration hole, and the moisture on the clothes in the inner cylinder is dehy...
