Background

The washing machine is designed as a device for washing laundry by using electricity, and generally, the washing machine includes: a tub for holding washing water; a rotating tub rotatably installed inside the tub; a pulsator rotatably installed at the bottom of the rotary tub; a motor and a clutch configured to rotate the rotary tub and the pulsator. When the rotary tub and the pulsator are rotated in a state in which laundry and detergent are introduced into the rotary tub, the pulsator stirs wash water together with the laundry introduced into the rotary tub, thereby removing dirt from the laundry.

In order to increase the washing capacity of the washing machine, a larger rotary tub is required, i.e., the height or diameter of the rotary tub needs to be increased. If the rotary tub has a larger size, the tub accommodating the rotary tub and the cabinet accommodating the tub also need to be increased as the rotary tub is increased. The increase of the cabinet corresponding to the appearance of the washing machine is limited by the space of the area for installing the washing machine, the position for installing the washing machine in a general user home is limited, and the purpose of increasing the capacity of the washing tub by increasing the cabinet of the washing machine is unrealistic, for example, how to increase the capacity of the rotary tub becomes a big problem which is troubled designers on the premise of not increasing the cabinet of the washing machine.

The appearance of the inner barrel without holes enables that no water exists between the inner barrel and the outer barrel, thereby achieving the purposes of cleaning and water saving; secondly, the precondition is provided for enlarging the effective volume of the inner barrel. The upper part of the non-porous inner barrel is provided with dewatering holes, the side wall of the inner barrel of the washing machine with the non-porous inner barrel is provided with a water channel, and when dewatering, water in the inner barrel enters the water channel through the dewatering holes under the action of centrifugal force, and the removed water is discharged to the outside of the washing machine. The water channel on the side wall of the inner barrel is formed by two parts in a melting way, and the water channel is divided into an inner part and an outer part along the central axis. The welded joint faces the circumferential direction of the washing tub and is easily directly impacted by the rotating water flow. If the welding is not qualified or after long-term use, water leakage may occur during dewatering.

The present invention has been made in view of this situation.

Example one

As shown in fig. 1-5, the present embodiment provides a water channel structure 1 of a washing machine, which is disposed on a wall of a washing tub 18 of the washing machine, and includes a first water channel portion 2 and a second water channel portion 3 fixedly connected to each other, and both of them together enclose a cavity channel 4 communicated with the washing tub 18; the cavity channel 4 has a first side wall 8 and a second side wall 9, the first side wall 8 and the second side wall 9 are oppositely arranged at a distance in a radial direction of the washing tub 18, and the junction 5 of the first waterway part 2 and the second waterway part 3 is located on the first side wall 8 and/or the second side wall 9.

The washing machine with the inner tub without holes has water channel in the side wall of the washing tub, and during dewatering, the water in the inner tub enters the water channel via the dewatering holes and the dewatered water is drained to the outside of the washing machine. The cavity passage 4 of the waterway structure 1 is provided on the side wall of the washing tub 18 to extend up and down in the height direction of the washing tub 18.

It should be noted that the lines of the joints marked with reference number 5 in the drawings do not actually exist, and are labeled for more clearly explaining the joints, and are used to indicate the positions of the joints, or to indicate the planes of the joints.

The first side wall 8 and the second side wall 9 of the waterway structure 1 of the present invention are side walls oppositely disposed at a certain distance in the radial direction of the washing tub 18, and the joint 5 of the first waterway part 2 and the second waterway part 3 is located on the first side wall 8 and/or the second side wall 9, so that the joint 5 is not in the rotation direction of the water flow, thereby avoiding the impact of the water flow on the weak joint 5, preventing the waterway from leaking water, and particularly avoiding the water leakage situation caused by the unqualified welding of the joint 5 or the long-term use of the joint 5.

The junction 5 of first water course portion 2 and second water course portion 3 can only be located on first lateral wall 8 or second lateral wall 9, also can be simultaneously on first lateral wall 8 and second lateral wall 9, so, the homoenergetic avoids junction 5 to lead to the fact great impact, avoids appearing the condition of leaking towards the circumferential direction of pail, avoids rotatory rivers to junction 5.

That is, the plane of the joint 5 of the first and

second waterway portions

2 and 3 at the first and

second sidewalls

8 and 9 is disposed at an angle of 0 to 180 ° with respect to the first and

second sidewalls

8 and 9. When the angle is 90 deg., the plane of the joint 5 is perpendicular to the first and

second side walls

8, 9. Alternatively, the plane of the joint 5 may be parallel to the radial direction of the washing tub 18, or may be disposed at an angle. Thus, the connection can be performed conveniently according to the shapes of the first water channel part 2 and the second water channel part 3, and the effect of preventing the connection part 5 from being impacted by strong force can be achieved.

There are three cases of the relationship between the plane in which the joint 5 on the first side wall 8 and the joint 5 on the second side wall 9 are located and the plane in which the midpoint line between both ends of the first side wall 8 in the circumferential direction and the midpoint line between both ends of the second side wall 9 in the circumferential direction are located:

in case 1, the plane where the joint 5 of the first side wall 8 and the joint 5 of the second side wall 9 are located is located on the plane where the midpoint line between the ends of the first side wall 8 and the second side wall 9 in the circumferential direction is located. In this case, the first waterway portion 2 and the second waterway portion 3 are bilaterally symmetrical, and the junction 5 is located at a central position.

In case 2, the plane where the joint 5 of the first side wall 8 and the joint 5 of the second side wall 9 are located intersects the plane where the midpoint line between the ends of the first side wall 8 and the second side wall 9 in the circumferential direction is located. In this case, the first waterway part 2 and the second waterway part 3 are complementarily fitted, and the joint 5 of the first side wall 8 and the joint 5 of the second side wall 9 are symmetrical about the central axis in the vertical direction.

In case 3, the plane where the joint 5 of the first side wall 8 and the joint 5 of the second side wall 9 are located is parallel to and located on one side of the plane where the midpoint line between the two ends of the first side wall 8 and the second side wall 9 in the circumferential direction is located. This situation is illustrated in fig. 3 and 4.

No matter which kind of circumstances, junction 5 can be avoided to junction 5 towards the circumferential direction of pail on junction 5 on 8 and the second lateral wall 9 on the first lateral wall, avoids rotatory rivers to cause great impact to junction 5, avoids appearing the condition of leaking.

As shown in fig. 5, when the washing tub 18 rotates in a clockwise direction, the water is thrown in an opposite direction, that is, the water rotates in a counterclockwise direction. Thus, after the water flow enters the cavity channel 4 of the waterway structure 1, a sidewall disposed opposite to the water flow direction in the circumferential direction of the washing tub 18 is the upstream surface 6. At this time, the joint 5 on the first side wall 8 and the joint 5 on the second side wall 9 are both far away from the upstream surface 6 and close to the backside surface 7, so that the pressure of water flow borne by the joint 5 can be further reduced, and water leakage caused by damage to the joint 5 is further avoided.
