Description

Dispensing device for washing machine and washing machine with same

technical field

The invention relates to the technical field of washing machines, in particular to a washing machine dispensing device with an eccentric flap and a washing machine with the device.

Background technique

With the development of washing machine-related technologies, some of the existing washing machines have heating and drying functions. However, during the heating and drying process, the water vapor generated by the washing tub diffuses upwards and enters the delivery device, forming condensed water droplets. When the water box is opened before adding detergent or when the water box is opened after washing, condensed water will drip onto the ground or the shell of the washing machine, which brings inconvenience to the cleaning of the environment; After the foam generated by the agent reaches a certain level, it usually enters the dosing device through the discharge port of the dosing device, and may bring washing dirt into it.

The reason is that the interface between the detergent dispensing device and the washing tub, that is, the water outlet of the dispensing device is an unobstructed opening, and the rising water vapor enters the dispensing device from the water outlet in reverse, and then forms a large number of condensed water droplets; The washing foam will also enter the delivery device from the water outlet, which will cause inconvenience to cleaning.

In view of the above problems, the existing common technical means are to smear hydrophilic and/or hydrophobic materials on different surfaces of the water box, and to supply cold water through a ventilating hose to cool down, etc., but none of them can solve the problem.

In view of this, the present invention is proposed.

Contents of the invention

The present invention aims to provide a washing machine dispensing device, which uses an eccentric flap structure at the water outlet to ensure smooth dispensing of water and prevent water vapor and washing foam from entering the dispensing device.

In order to achieve the above object, the present invention specifically adopts the following technical solutions:

A washing machine dispensing device, the bottom of the dispensing device is provided with a water outlet 2 connected to the washing bucket, the lowest part of the dispensing device is provided with a water outlet 2, and an eccentric flap 1 sealingly matched with the water outlet 2 is also provided. The flap 1 is turned over to open the water outlet 2 by the gravity of the water stored inside the feeding device, or turned over to close the water outlet 2 by its own gravity.

In the above scheme, the eccentric flap 1 that is opened and closed by the water gravity and its own gravity is installed at the water outlet of the washing machine feeding device, which can effectively block the water vapor generated in the washing tub due to heating or drying, and prevent water Steam entering the dispensing device or water box forms a large sheet of condensed water, which reduces the user experience, and also reduces the chance of washing foam bringing dirt into the dispensing device.

A further solution of the present invention is: the eccentric flap 1 includes two parts whose mass and surface area are inversely proportional, and the junction of the two parts is the rotation axis 13 of the eccentric flap 1, so that the eccentric flap 1 rotates around the rotation axis 13 to Realize the opening and closing of the water outlet 2.

In the above scheme, the center of gravity of the eccentric flap 1 is offset from the geometric center, and its own mass distribution is unbalanced, so that the eccentric flap 1 rotates around the axis, and when it is subjected to an external force greater than its own gravity, the rotation in the direction of the external force occurs. When not affected by external force, the heavier part is turned down by gravity and remains in the lower part.

A further solution of the present invention is: the inner side of the water outlet 2 is provided with limit plates that are respectively offset against the upper and lower surfaces of the eccentric flap 1, so that the rotation angle of the eccentric flap 1 when opening and closing the water outlet 2 is not greater than 90°.

In the above scheme, since the weight of the eccentric flap 1 is not uniform, when it is not subjected to external force, the heavier part will turn down with the gravity, so that the flap will tilt up and the water outlet will not be closed. The position of the flap 1 is restricted so that it can open and close the water outlet; when the water outlet 2 is closed, the eccentric flap 1 is parallel to the horizontal plane and is in a horizontal position; when the water outlet 2 is opened to the maximum, the eccentric flap 1 is perpendicular to the Horizontal plane, in a vertical position.

A further solution of the present invention is: the limiting plate includes a first limiting plate 21 abutting against the edge of the upper surface of the lighter part of the eccentric flap 1, and a second limiting plate 22 abutting against the edge of the lower surface of the heavier part, Make the eccentric flap 1 that is rotated by its own gravity stay in a horizontal position.

In the above solution, the horizontal position is the position when the eccentric flap 1 is parallel to the horizontal plane, and the heavier part of the eccentric flap 1 will turn downwards under the action of gravity, so a second limiting plate 22 is set on the edge of its lower surface Hold up the heavier part; at the same time, in order to prevent the eccentric flap 1 from being turned upward by the impact of the water flow from the washing tub below, a first limiting plate 21 is set on the edge of the upper surface of the lighter and larger area. Under the combined action of the first limiting plate 21 and the second limiting plate 22, the two sides of the eccentric flap 1 turned to the horizontal position are respectively limited, so that the eccentric flap 1 stays in the horizontal position and will not Unnecessary turning action due to large impact force. In addition, the first limiting plate 21 and the second limiting plate 22 respectively abut against the eccentric flap 1 , so that the eccentric flap 1 in the horizontal position plays a role of sealing the water outlet.

A further solution of the present invention is: the two ends of the rotation axis 13 are respectively provided with rotating shafts 131, which are rotatably connected to the fixed point 24 inside the water outlet 2, and the top of the fixed point 24 is provided with a third limiting plate 23 , offset against the eccentric flap 1 rotated by the gravity of the water, so that the rotation angle of the eccentric flap 1 is not greater than 90°; preferably, the third limiting plate 23 is arranged perpendicular to the horizontal plane along the direction of the rotation axis 13 .

In the above scheme, when the eccentric flap 1 is subjected to the force of water gravity, the heavier part turns upward and the lighter part turns downward regardless. If the impact force of the water body on the flap is too large, the heavier part will turn over 90°, The eccentric flap 1 cannot return to the horizontal position, so the third limiting plate 23 is provided to limit the rotation angle of the eccentric flap 1 . The vertical upright of the eccentric flap 1 is most conducive to the discharge of water, so it is preferable to arrange the third limiting plate 23 along the direction of the rotation axis 13 perpendicular to the horizontal plane.

A further solution of the present invention is: the eccentric flap 1 is divided into a first part 11 and a second part 12, and the length of the maximum perpendicular segment from a point on the outer circumference of the first part 11 to the rotation axis 13 is greater than that from a point on the outer circumference of the second part 12 to The maximum vertical segment length of the rotation axis 13, and the surface area of the first part 11 is larger than that of the second part 12, the first part 11 is subjected to greater water gravity and turns downwards, and the second part 12 turns upwards to open the drain; the first part The mass of 11 is smaller than that of the second part 12. After the water body is drained, the second part 12 is turned downward by greater gravity, the first part 11 is turned upward, and the eccentric flap 1 returns to the horizontal position, so that the drain is closed.

A further solution of the present invention is: the delivery device is provided with a shrinkage portion 3 extending downward from the lower surface and shrinking gradually, the water outlet 2 is arranged at the lowest point of the shrinkage portion 3, and the lowest point of the inner wall of the neck portion 3 is set There is a fixed point 24 corresponding to the rotating shaft 131 of the eccentric flap 1, and the length of the maximum perpendicular segment from the point on the outer periphery of the second part 12 to the axis of rotation 13 is less than the distance that the necking part 3 extends downwards, so that the eccentric flap 1 The highest point when perpendicular to the horizontal plane is lower than the lower surface of the delivery device.

In the above solution, when the eccentric flap 1 stands vertically under the gravity of the water, its upper end is lower than the bottom plane of the delivery device, so as to prevent the liquid splashed by the rotation of the flap from remaining on the bottom surface of the delivery device.

A further solution of the present invention is: the lower surface of the second part 12 is provided with a protruding reinforcing rib 121, so that the center of gravity of the second part 12 is biased towards the reinforcing rib 121; preferably, the thickness of the second part 12 of the eccentric flap 1 is greater than The thickness of the first part 11.

In the above scheme, since the eccentric flap 1 is a plate structure, the centers of gravity of the first part 11 and the second part 12 are mostly located on the plane where the middle layer of the plate is located. The present invention is provided with a The raised rib 121 makes the center of gravity of the second part 12 deviate from the middle layer of the plate so as to be close to the position of the rib. When the eccentric flap 1 is upright and free from external force, due to the natural center of gravity of the heavier second part 12 The deflection makes it easier for the second part 12 to turn downwards, so that the eccentric flap 1 returns to a horizontal position. Wherein, due to the consistency of the flap material, it is preferable to increase the thickness of the second part 12 to improve its quality.

A further solution of the present invention is: the side of the third limiting plate 23 facing the center of the water outlet 2 is provided with a beveled edge.

In the above scheme, since the position of the third limiting plate 23 is higher than the horizontal position of the flap and is set upright on the horizontal plane, it will hinder the discharge of water to a certain extent, so the third limiting plate 23 is set on the side close to the center of the water outlet A beveled edge that facilitates the drainage of water bodies.

A further solution of the present invention is: the eccentric flap 1 is adapted to the water outlet 2, the shape of the first part 11 is a semicircle with the axis of rotation 13 as the diameter, and the shape of the second part 12 is that the axis of rotation 13 is the long side rectangle.

The present invention also provides a washing machine with the throwing device. The throwing device of the washing machine is provided with an eccentric flap 1 and a limit plate corresponding to the eccentric flap 1. The eccentric flap 1 is respectively subjected to water gravity and its own Rotate by gravity to realize the opening and closing of the water outlet 2.
