Problems solved by technology

In the washing machine of the present invention, a constant volume box is set on the water inlet pipeline of the inner cylinder to accurately measure the water intake, so as to solve the problem that the water intake of the non-porous inner cylinder cannot be accurately measured, and then realize the rotatable seal. The purpose of accurately measuring the water level of the inner cylinder; at the same time, the inner and outer cylinders of the drum washing machine are combined into one to realize the purpose of expanding the washing capacity of the washing machine

Embodiment 1

[0050] like figure 1 and figure 2 As shown in the figure, a washing machine is introduced in this embodiment. A sealed inner cylinder 1 is installed in the shell 2 of the washing machine. The inner cylinder 1 is communicated with the water inlet water source of the washing machine through the water inlet pipe 17, and the water inlet pipe 17 is provided with a constant volume box. 40. When the water level in the fixed volume box 40 reaches a high water level, the water inlet of the fixed volume box 40 is closed, the water outlet is opened, and water is fed into the inner cylinder 1; when the water level in the fixed volume box 40 reaches a low water level, the water in the fixed volume box 40 The water inlet is opened and the water outlet is closed; the water level corresponding to the inner cylinder can be obtained by detecting the opening times of the water outlet of the constant volume box 40 .

[0051] like figure 1 As shown, in this embodiment, the constant volume box 4...

Embodiment 2

[0059] In this embodiment, a method for controlling a washing machine is introduced. The water source of the washing machine flows into the constant volume box, and by controlling the valve body set in the constant volume box, the constant volume box can store water to a high water level, and then the constant volume box is stored in the constant volume box. The water is discharged into the inner cylinder until the water level of the constant volume box reaches the low water level, and the number of times of drainage of the constant 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. Feed water into the inner tub of the washing machine from the water inlet pipe of the washing machine;

[0062] Step 2. The water inlet of the constant volume box is opened, the water outlet is closed, and the water inlet of th...

Embodiment 3

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

[0073] like 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 after the door cover 4 is closed. Lock the elastic force, make the inner cylinder cover 8 and the inner cylinder cylinder mouth 101 in sealing contact, and make the inner cylinder cover 8 rotate together with the inner cylinder 1, so as to realize that the inner cylinder cover 8 is buckled to the inner cylinder cylinder mouth 101 after the door cover 4 is closed. The purpose of sealing the inner cylinder 1.

[0074]Through the above arrangement, to achieve the sealing of the inner cylinder cover pressed by...

Abstract

The invention relates to a washing machine and a control method. A sealed inner barrel is installed in the shell of the washing machine. The inner barrel is connected to the water inlet of the washing machine through a water inlet pipe. , the water inlet is closed, the water outlet is opened, and water enters the inner cylinder; when the water level in the fixed volume box reaches a low water level, 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 fixed volume box. Through the above device and method, a constant volume box is installed on the water inlet pipe of the washing machine, and the water is stored in the constant volume box and then drained into the inner cylinder, so that the accurate water level in the inner cylinder of the washing machine can be obtained by detecting the number of drainage times of the constant volume box At the same time, the water level detection device of the washing machine is arranged on the water inlet pipe of the inner cylinder, so that the washing machine with dual functions of rotating the inner cylinder and holding water can work normally; The volume of the cylinder improves the washing capacity of the washing machine.

Description

technical field [0001] The invention belongs to the technical field of washing machines, in particular to a washing machine with only a rotatable inner tub capable of holding water, 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 tub and an outer tub that are fitted with each other, the outer tub is sealed for holding water, the inner tub is used for storing clothes, and the inner tub is rotated to beat and wash the clothes; A dehydration hole is provided, 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 dehydrated when the inner cylinder rotates at a high...
