Description

Washing machine placing device and washing machine having the same

Technical field

The present invention relates to the field of washing machine technology, and in particular to a washing machine dispensing device with an eccentric flap and a washing machine having the same.

Background technique

With the development of related technologies of washing machines, some existing washing machines have heating and drying functions, but in the heating and drying process, the water vapor generated by the washing tub spreads up into the dispensing device to form condensed water droplets, and the user is in the laundry. In the process of adding the detergent to the front water tank or when the water tank is pulled out after washing, the condensation water drops on the floor or the outer casing of the washing machine, which causes inconvenience to the cleaning of the environment; in addition, the washing tub is washed by the inside. After the foam produced by the agent reaches a certain level, it usually enters the delivery device through the discharge port of the dispensing device, and may bring washing dirt into it.

The reason is that the interface between the detergent delivery device and the washing tub, that is, the water outlet of the dispensing device is an unobstructed opening, and the rising water vapor reverses from the water outlet into the dispensing device, thereby forming a large amount of condensed water droplets; The washing foam also enters the delivery device from the water outlet, which is inconvenient for cleaning.

In view of the above problems, the conventional technical means is to apply hydrophilic and/or hydrophobic materials on different faces of the water box, and to cool the cold water through a ventilating hose, etc., but the problem cannot be cured.

In view of this, the present invention has been specifically proposed.

Summary of the invention

The invention aims to provide a washing machine dispensing device, which adopts an eccentric flap structure at the water outlet to ensure the smooth discharge of the water body while preventing the water vapor and the washing foam from entering the placing device.

To achieve the above objective, the present invention specifically adopts the following technical solutions:

A washing machine placing device, the bottom of the placing device is provided with a water outlet 2 connected to the washing tub, the bottom of the placing device is provided with a water outlet 2, and an eccentric flap 1 sealingly matched with the water outlet 2 is further provided, the eccentricity The flap 1 is turned over by the internal storage water gravity of the dispensing device to open the water outlet 2, or is closed by the own gravity to close the water outlet 2.

In the above solution, the eccentric flap 1 which is opened and closed by the water body weight and the gravity of the self-gravity is installed at the water outlet of the washing machine dispensing device, and the water vapor generated in the washing tub due to heating or drying can be effectively blocked to prevent water. The vapor enters the dispensing device or water tank to form a large condensate that reduces the user experience and also reduces the chances of the washing foam bringing dirt into the dispensing device.

According to a further aspect of the present invention, the eccentric flap 1 includes two portions having an inverse ratio of the mass to the surface area. The boundary between the two portions is the rotation axis 13 of the eccentric flap 1, and the eccentric flap 1 is rotated about the rotation axis 13 to The opening and closing of the water outlet 2 is achieved.

In the above solution, 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 the external force is greater than its own gravity, the rotation of the external force occurs. The heavier part is not turned down by gravity and remains in the lower part when it is not affected by external force.

According to a further aspect of the present invention, the inner side of the water outlet 2 is provided with a limiting plate respectively abutting the upper and lower surfaces of the eccentric flap 1, so that the angle of rotation of the eccentric flap 1 when opening and closing the water outlet 2 is not more than 90°.

In the above solution, since the eccentric flap 1 has a non-uniform weight, when the external force is not applied, the heavier portion is turned downward with the gravity, so that the flap is lifted and the water outlet cannot be closed, so the eccentric structure is used for eccentricity. The position of the flap 1 is restricted to enable the opening and closing of 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 is in a vertical position.

According to a further aspect of the present invention, the limiting plate includes a first limiting plate 21 that abuts an upper surface edge of a lighter portion of the eccentric flap 1 and a second limiting plate 22 that abuts the lower surface edge of the heavier portion. The eccentric flap 1 that is rotated by its own gravity stays in a horizontal position.

In the above solution, the horizontal position is a position when the eccentric flap 1 is parallel to the horizontal plane, and the heavier portion of the eccentric flap 1 is turned downward by gravity, so the second limiting plate 22 is disposed at the edge of the lower surface thereof. The heavier portion is lifted; and at the same time, in order to prevent the eccentric flap 1 from being reversely inverted by the flow of water from the lower washing tub, the first limiting plate 21 is provided at the upper surface edge of the lighter and larger portion. Under the joint action of the first limiting plate 21 and the second limiting plate 22, the two sides of the eccentric flap 1 which are turned to the horizontal position are respectively restricted, so that the eccentric flap 1 stays in the horizontal position and is not short-timed. Excessive flipping action due to large impact forces. Further, 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 functions to seal the water outlet.

According to a further aspect of the present invention, the two ends of the rotating shaft 13 are respectively provided with a rotating shaft 131, and are rotatably connected to a fixed position 24 on the inner side of the water outlet 2, and a third limiting plate 23 is arranged on the top of the fixed position 24. Corresponding to the eccentric flap 1 rotated by the water body weight, the rotation angle of the eccentric flap 1 is not more than 90°; preferably, the third limiting plate 23 is disposed perpendicular to the horizontal plane along the rotation axis 13 direction.

In the above solution, when the eccentric flap 1 is subjected to the water body weight force, the heavier portion is turned upside down and is lightly inverted, and if the impact force of the water body on the flap is too large, the heavier portion is turned over 90°. The eccentric flap 1 cannot be returned to the horizontal position, so the third limiting plate 23 is provided to limit the rotation angle of the eccentric flap 1. The vertical erecting of the eccentric flap 1 is most advantageous for the discharge of the water body, so that the third limiting plate 23 is preferably arranged perpendicular to the horizontal plane in the direction of the axis of rotation 13 .

According to a further aspect of the present invention, the eccentric flap 1 is divided into a first portion 11 and a second portion 12, and a maximum vertical length of the point on the outer circumference of the first portion 11 to the rotation axis 13 is greater than a point on the outer circumference of the second portion 12 to The maximum vertical length of the axis of rotation 13 and the surface area of the first portion 11 is greater than the second portion 12, the first portion 11 is flipped downward by the larger water body weight, and the second portion 12 is turned upside down to open the drain opening; The mass of 11 is smaller than that of the second portion 12. After the water body is drained, the second portion 12 is turned downward by a large gravity, the first portion 11 is turned upside down, and the eccentric flap 1 is returned to the horizontal position, so that the drain port is closed.

According to a further aspect of the present invention, the dispensing device is provided with a constricted portion 3 extending downward from the lower surface and gradually contracting, and the water outlet 2 is disposed at the lowest point of the constricted portion 3, and the lowest portion of the inner wall of the constricted portion 3 is provided. There is a fixed position 24 corresponding to the rotating shaft 131 of the eccentric flap 1, and the maximum vertical length of the point on the outer circumference of the second portion 12 to the rotation axis 13 is smaller than the downward extending distance of the constricted portion 3, so that the eccentric flap 1 The highest point perpendicular to the horizontal plane is lower than the lower surface of the dispensing device.

In the above solution, when the eccentric flap 1 is vertically erected by the water body weight, the upper end thereof is lower than the bottom plane of the dispensing device to prevent the liquid splashed by the flap rotation from remaining on the bottom surface of the inside of the dispensing device.

In the above solution, since the eccentric flap 1 is a plate structure, the center of gravity of the first portion 11 and the second portion 12 is mostly located on a plane on which the intermediate layer of the plate is located, and the present invention is provided on the lower surface of the heavier second portion 12. The raised reinforcing ribs 121 are such that the center of gravity of the second portion 12 is offset from the intermediate layer of the sheet so as to be close to the position of the ribs. When the eccentric flap 1 is upright and free from external force, the center of gravity of the heavier second portion 12 is natural. The biasing makes it easier for the second portion 12 to flip down, returning the eccentric flap 1 to a horizontal position. Among them, due to the consistency of the flap material, it is preferable to increase the thickness of the second portion 12 to improve its quality.

According to a further aspect of the present invention, the side of the third limiting plate 23 facing the center of the water outlet 2 is provided with a beveled edge.
