Embodiment 1

[0050] like Figure 1 to Figure 5 As shown, the deceleration clutch device described in this embodiment includes an input shaft 110 and an output shaft 120, both of which are hollow shafts, and are rotatably and sealedly connected to form a through hollow channel. The hollow channel provides a travel path for the gas, and the washing machine using the deceleration clutch device can realize the function of ventilating the inner tub 1 through the deceleration clutch device to generate air bubbles by connecting the hollow channel with the air source.

[0051] Further, as Figure 4 As shown, the lower end of the output shaft 120 is rotatably inserted into the hollow channel of the input shaft 110 , and a first sealing member 101 is provided between the outer wall of the output shaft 120 and the inner wall of the input shaft 110 . Specifically, the output shaft 120 includes a rotating shaft body and a plug portion 123 inserted into the input shaft 110 , and the first seal 101 is s...

Embodiment 2

[0072] like Figure 11 As shown, this embodiment provides a washing machine, and the washing machine has the deceleration clutch device described in the first embodiment. The difference between the washing machine and the first embodiment above is that the lower end of the communication pipe 130 is connected to the water inlet pipe 7, and the other end of the water inlet pipe 7 is connected to the water inlet valve of the washing machine.

[0073] In this embodiment, when the washing machine enters water, the water inlet valve is opened to supply water to the water inlet pipe 7 . The water flow enters the communication pipe 130 through the water inlet pipe 7 , and then passes through the input shaft 110 and the output shaft 120 in sequence, and finally passes through the water outlet on the surface of the pulsator 6 . The hole 67 goes into the inner tub 1 .

[0074] In this embodiment, the hollow channel of the deceleration clutch device is used to realize the function of wat...

Embodiment 3

[0076] This embodiment provides a non-porous inner tub washing machine, and the non-porous inner tub washing machine has the deceleration clutch device described in the first embodiment. The difference between the non-porous inner tub washing machine and the above-mentioned first embodiment is that the inner tub is a non-porous inner tub, the lower end of the communication pipe is connected with an air chamber, and the air chamber is connected with a pressure sensor through a pressure transmission pipe. The pressure sensor can detect the air pressure in the air chamber, so as to obtain the water pressure at the installation height of the air chamber, and then obtain the water level in the inner tub.

[0077] Further, the lower end of the communication pipe is also communicated with the drainage pipeline of the non-porous inner tub washing machine, and the water in the inner tub can be directly discharged through the hollow passage of the deceleration clutch device.

[0078] In...

Abstract

The invention belongs to the technical field of washing machines, and discloses a speed reduction clutch device of a washing machine, the washing machine and a control method. The speed reduction clutch device comprises an input shaft and an output shaft; the input shaft and the output shaft are hollow shafts; and the input shaft and the output shaft are rotatably and hermetically connected to form a through hollow channel. The washing machine comprises an inner barrel, an impeller and a driving motor; the input shaft is connected with the driving motor; the output shaft is connected with the impeller; and the hollow channel is communicated with the interior of the inner barrel. According to the invention, the communication between the interior and the exterior of the inner barrel is achieved through the speed reduction clutch device, then the function of generating bubbles by introducing air into the inner barrel can be achieved, clothes are separated from the impeller through the bubbles, and clothes are separated from one another through the bubbles, so that wear of the clothes is relieved, and thread scraps are reduced. Or the speed reduction clutch device can also realize the function of feeding water from the bottom of the inner barrel, or can also realize the water level detection and drainage functions for a washing machine with a non-porous inner barrel.

Description

technical field [0001] The invention belongs to the technical field of washing machines, and in particular relates to a deceleration clutch device of a washing machine, a washing machine and a control method. Background technique [0002] The pulsator washing machine drives the water in the washing tub and the clothes to agitate together through the rotation of the pulsator during the laundry washing process, which has achieved the purpose of cleaning the clothes. However, during the washing process, the direct contact between the inner barrel of the impeller and the clothes will cause the clothes to wear. For example, the rotating impeller contacts the clothes and wears the clothes. At the same time, the clothes are stirred during the washing process, resulting in mutual contact friction, which will also lead to excessive clothing. Wear, damage. The aggravation of clothing wear will also lead to an increase in lint during the washing process, affecting the washing effect o...
