TECHNICAL FIELD

The present invention belongs to the field of washing devices and particularly relates to a washing feeding device applied to a washing machine.

BACKGROUND

A washing feeding device of a washing machine is installed on a machine body. A feeding chamber or a liquid storage chamber is arranged on the washing feeding device to make a user add a washing additive to the feeding chamber or the liquid storage chamber manually, and then introduced water of the washing machine is used to flush the added washing additive to a water holding container of the washing machine. The current washing additive generally has two forms: one is washing powder in a solid shape and the other is a liquid detergent, a disinfectant, a softener and the like.

Washing powder in a powder shape is generally placed into a chamber directly. After washing is started, the introduced water can be used to directly flush the washing powder away. However, only when a liquid washing additive is fed in a closed space, can it ensure that the additive is firstly diluted by flowing water in a washing process and then the diluted additive is washed away.

At present, the washing feeding device, in order to respectively feed different forms of washing additives, generally adopts the following manner: the washing powder in a powder shape and the liquid washing additives are respectively fed by different feeding chambers, requiring that corresponding structures are installed accordingly in the corresponding feeding chambers.

Therefore, how to set an adjusting structure in the same feeding chamber to make the feeding chamber simultaneously feed the solid and liquid washing additives has become a hot research and development issue.

Accordingly, the present disclosure is proposed herein.

SUMMARY

The technical problem to be solved in the present disclosure is to overcome defects of the prior art and a washing feeding device is provided for realizing a purpose of adaptively feeding different forms of washing additives, such as liquid washing additives and solid washing additives, respectively. Another objective of the present disclosure is to provide a washing feeding device to realize a purpose of reducing residue of the washing additives in chambers.

In order to solve the above technical problem, the basic concept of the technical solution disclosed in the present disclosure is as follows.

A washing feeding device comprises a water box, a feeding box installed in the water box, and at least one feeding chamber arranged in the feeding box. A stop plate, for preventing water from flowing toward a water outlet, is installed in the feeding chamber. A siphon is arranged on the stop plate for communicating one side with the other side, so that at an upstream side of the stop plate, a detergent and water flow fed to the water box from the feeding box flows to a downstream side of the stop plate along the siphon, and flows out from the water box via the water outlet after being blocked by the stop plate and accumulated up to a water level for triggering a siphonic effect.

Further, the siphon is an inverted U-shaped flow channel. Two ends of the flow channel are respectively located at two sides of the stop plate. A height of the flow channel at a corner is not smaller than a height of a top end of the stop plate.

Further, one end of the inverted U-shaped flow channel at the upstream side of the stop plate is a water inlet end, and another end of the inverted U-shaped flow channel at the downstream side of the stop plate is a water outlet end. The water inlet end and the water outlet end are apart from a bottom wall of the feeding chamber by an interval for allowing the detergent and the water flow to flow into or out of the flow channel.

Further, the water inlet end of the inverted U-shaped flow channel is higher than the water outlet end of the inverted U-shaped flow channel. Preferably, the bottom wall of the feeding chamber is arranged obliquely downward toward the water outlet in a direction vertical to the stop plate.

Further, the siphon comprises a main body which is fixedly installed or integrated onto the stop plate and is a tubular shape extending vertically and being hollow inside. A hollow portion of the main body with tubular shape is separated by the stop plate into two independent portions: a water inlet flow channel and a water outlet flow channel. A top of the main body with tubular shape is buckled with an upper cover in a sealing manner. A lower side of the upper cover is provided with a groove sinking inward. The groove is used for communicating tops of the water inlet flow channel and the water outlet flow channel.

Further, the top of the main body with tubular shape is provided with a circle of sealing rib protruding upward. Two circles of coordinating ribs protruding downward are arranged in the periphery of the upper cover. A groove is formed in middle of the coordinating rib at an inner circle. The two circles of coordinating ribs are separated by an interval to form an insertion slot. The sealing rib is inserted into the insertion slot to form sealed insertion between the upper cover and the tubular main body.

Further, the main body with tubular shape and the stop plate are integrally formed. The upper cover is buckled to and fixedly connected to the top of the main body with tubular shape.

Further, two sides, perpendicular to the stop plate, of the main body with tubular shape are planes. Two sides, parallel with the stop plate, of the main body with tubular shape are arc faces protruding toward an outer side of the main body.

Further, the stop plate is installed in the feeding chamber in an overturning manner. The stop plate is in vertical position while the detergent is fed into the water box from the feeding chamber, and the stop plate is in horizontal or oblique position while washing powder is fed into the water box by the feeding chamber, so as to flush the washing powder to the water outlet. Preferably, two ends of the top of the stop plate are respectively provided with rotary shafts protruding outward. The two rotary shafts are arranged coaxially and penetrate respectively into side walls of the feeding chamber, such that the stop plate is installed onto the feeding box in an axial rotation manner.

Further, when the stop plate is at the vertical position, two sides of the stop plate are correspondingly are contact with inner walls of the feeding chamber, a lower side of the stop plate is correspondingly contact with the bottom wall of the feeding chamber. Preferably, at least one limit portion protruding to the inside of the feeding chamber is arranged on the inner walls of the feeding chamber for making the limit portion abut against the stop plate to limit when the stop plate is in the vertical position.

By the above technical solution, the present disclosure has the following advantageous effects compared with the prior art.

1. Through the above arrangement, the detergent added by the user into the feeding chamber can be blocked by the stop plate, and the detergent diluted flows to the downstream side of the stop plate via siphon. Thereby it is avoided that the detergent flows into the water box directly in case of not being diluted by water, and a purpose of improving the efficiency of diluting the detergent and enlarging the distribution area of the detergent is achieved.

2. Through the above arrangement, the inlet water of the water box flows through the gap portion of the baffle board to wash the bottom wall of the feeding chamber blocked below the baffle board, thereby avoiding residue of the washing powder at the water outlet of the feeding chamber and realizing a purpose of preventing residue of the washing powder at the water outlet of the feeding chamber shielded by the baffle board.

3. Through the arrangement of the baffle board capable of overturning, a corresponding using state is adjusted when the feeding device respectively feeds the liquid and solid washing additives, thereby ensuring smooth feeding of the additives.

4. Via a downpipe arranged vertically on the feeding box of the feeding device in a penetrating manner, residual water on a top surface of the feeding box flows to the bottom of the water box below the feeding box through the downpipe, thereby avoiding residue of water on the top surface of the feeding box, and further preventing the residual water from leaking to the outside of the washing machine when the user pulls the feeding box out.

5. By arranging the blocking rib at the periphery of the siphon, the siphon and the feeding chamber are separated, to prevent the siphon from triggering siphoning by mistake due to increase of the liquid level at the siphon caused by surging liquid in the feeding chamber in a process of pulling the feeding box, thereby realizing a purpose of preventing “surging” of the siphon to avoid triggering siphoning by mistake.

6. By arranging a hollow portion located at the periphery of the siphon on the cover plate of the feeding chamber, the inlet water for washing on the top surface of the feeding box flows into the feeding chamber along the hollow portion, thereby avoiding residue of the inlet water on the top surface of the feeding box. Meanwhile, water on the top surface of the feeding box flows into the feeding chamber along the hollow portion close to the siphon, water flows downward along an outer wall of the siphon to wash an outer wall surface of the siphon, thereby avoiding residue of the detergent on the outer wall of the siphon and generation of water stain.

Meanwhile, the structure of the disclosure is simple, remarkable effects and is widely applied.

Accompanying drawings will be incorporated below to further describe specific embodiments of the present disclosure in details.
