Description

Technical Field

[0001] The present invention belongs to the field of household washing appliances, and specifically, relates to a washing additive dispensing device for a washing machine; in particular, it relates to a washing additive dispensing device capable of preventing water in a water storage tank from splashing back; in particular, it also relates to a washing machine using the above-mentioned washing additive dispensing device. Background Art

[0002] With the continuous improvement of people's living standards, washing machines have become one of the essential household appliances for family life. The drum washing machine and the fully automatic pulsator washing machine in the prior art are usually provided with a washing additive delivery device for delivering detergent into the washing barrel of the washing machine. Generally, the washing additive is directly discharged into the water tank through the water outlet by the delivery structure through the water inlet. The existing waterway is generally integrated on the upper cover of the delivery device, and the water outlet provided on the upper cover enters the water tank downward, and the water flow flowing downward into the water tank will have a certain falling speed under the action of water pressure and gravity, and the water flow flowing into the water tank through the waterway will produce a certain splash at the bottom wall of the water tank. The water flow with too much splash will splash onto the inner wall of the water tank, which will cause liquid to hang on the side wall of the water tank, form residual water, and cause pollution to the side wall of the water tank to form water marks. At the same time, when the splashing water flow in the water tank is too large, it will also cause the splashing water flow to splash out of the water tank from the front opening of the water tank. In addition, if too high a splashing water flow is generated at the water storage tank below the water outlet of the water channel, the splashing water may splash back into the water channel on the upper cover.

[0003] In view of this, the present invention is proposed. Summary of the invention

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0039] like Figures 1 to 11 As shown, an embodiment of the present invention introduces a washing additive delivery device for a washing machine, which includes a water storage tank 1 for feeding water into a washing tub of the washing machine, the water storage tank 1 being a hollow cavity with an opening at the front end and an open top surface, and a dispenser box 2 which can be pulled outward and pushed inward for loading is installed inside the cavity; a liquid storage chamber 201 for holding washing additives such as detergents and softeners is provided on the dispenser box 2; the liquid storage chamber 201 can be composed of an independent chamber and detachably installed on the dispenser box 2, or it can be a liquid storage tank 2011 integrated on the dispenser box 2 for holding washing additives; a water storage tank outlet 101 is provided at the front end of the bottom of the water storage tank 1, so that the washing additive mixture and the inlet water flow can flow out of the water storage tank 1 through the water storage tank outlet 101 and enter the washing tub of the washing machine. The slide rail between the dispenser box 2 and the water tank 1 facilitates the dispenser box 2 to be smoothly drawn outward and pushed inward; the top opening of the water tank 1 is buckled with an upper cover 3, and the upper cover 3 buckles and closes the upper opening of the water tank to achieve the effect of shielding the inside of the water tank 1. At the same time, a water channel 300 is integrated inside the upper cover 3, and the water channel 300 is used to introduce the incoming water into the dispenser box 2, lead out the washing additives injected into the chamber set on the dispenser box 2, introduce the inlet water flow of the washing machine, lead out the inlet water and / or the washing additive mixture into the washing machine drum, etc.; of course, the water channel 300 can also feed water into the water tank 1, so that the inlet water flow of the washing machine and / or the washing additive mixture flows into the water tank 1, and then flows into the washing machine drum through the water tank 1.

[0040] In the embodiment of the present invention, the water tank 1 is also connected to an automatic dispensing device for extracting the detergent additives in the dispenser box 1 into the water tank 1; a water tank inlet 102 is provided on the right side of the water tank 1, and water is taken into the water tank 1 by the water inlet 102, and is mixed with the detergent additives discharged from the integrated water outlet 304 to form a detergent additive mixed liquid; a water tank water inlet 103 and a water outlet water inlet 104 are provided at the bottom of the water tank 1, and the detergent additive mixed liquid in the water tank 1 is guided by the water tank water inlet 103 and the water outlet water inlet 104 to flow out from the water tank outlet 101 provided at the front end of the bottom of the water tank 1 and enter the washing drum of the washing machine.

[0041] In an embodiment of the present invention, the washing additive dispensing device is also provided with an automatic dispensing unit for automatically extracting and dispensing the washing additive into the waterway; the automatic dispensing unit may be any existing structure; in an embodiment of the present invention, the automatic dispensing unit may be configured as follows, but the protection scope of the present invention is not limited to the following configuration: the automatic dispensing unit includes a pump, and the dispenser box 2 is connected to the integrated waterway 300 via the pump, so that the washing additive contained in the dispenser box 2 may be automatically pumped into the integrated waterway 300 and discharged into the water storage tank 1 via the integrated waterway outlet 304.

[0042] like Figures 1 to 5 As shown, in the embodiment of the present invention, the upper cover 3 includes an integrated water channel lower cover 302 and an integrated water channel upper cover 301 which are interlocked, and grooves recessed toward each other are provided at the connecting surfaces of the integrated water channel lower cover 302 and the integrated water channel upper cover 301, and the integrated water channel lower cover 302 and the integrated water channel upper cover 301 are sealedly connected to each other up and down, so that the above-mentioned grooves directly form a water channel 300 integrated inside the upper cover 3.

[0043] The integrated water channel lower cover 302 is provided with an integrated water channel outlet 304 for the washing additive mixture and / or the incoming water flow in the integrated water channel 300 to flow into the water storage tank 1. An air vent 305 is provided on the left side of the integrated water channel outlet 304 to ensure that after the water inlet is stopped, air is exchanged into the water channel 300 through the air vent 305, so that the residual liquid in the water channel 300 can be completely discharged to the water storage tank 1 below under the action of atmospheric pressure, thereby achieving the effect of emptying the residual water in the water channel.

[0044] When the washing machine is working, in order to ensure that the water in the water channel 300 is drained after the water inlet is stopped, an air hole 305 is added in the water channel 300. Because some water will flow out of the air hole 305 during the water inlet process, in order to ensure that the water flow rate flowing out of the air hole 305 is within a certain range, the air hole 305 is opened upward from the water channel 300 and has a diameter of less than 2 mm to prevent the liquid in the water channel 300 from flowing out from the air hole 305; preferably, in order to further prevent the liquid in the water channel 300 from overflowing from the air hole 305, a breathable valve can be installed at the air hole 305, so that under the action of the breathable valve, the gas can flow through the air hole 305 and the liquid in the water channel 300 cannot flow out.

[0045] In the embodiment of the present invention, a water tank outlet 101 is provided at the front end of the bottom of the water tank 1, and a water outlet diversion groove 104 is provided around the water tank outlet 101, which is gradually inclined upward along the periphery of the water tank outlet 101 toward the direction away from the water tank outlet 101. The right side of the water outlet diversion groove 104 is connected to a water tank diversion groove 103 provided at the upper end of the bottom of the water tank 1, so that the detergent additive mixture in the water tank 1 can be thoroughly discharged into the washing machine through the water tank diversion groove 103 and the water outlet diversion groove 104.

[0046] like Figures 1 to 5 As shown, an embodiment of the present invention introduces a washing additive delivery device, including a water tank 1, an upper cover 3 buckled on the top of the water tank, a waterway 300 integrated inside the upper cover 3; the bottom wall of the upper cover 3 is provided with a waterway outlet 304 opened toward the water tank 1; the upper cover 3 and / or the water tank 1 is provided with a splash-proof structure to prevent the splashing of the incoming water flow entering the water tank 1 from the waterway outlet 304. By adding the splash-proof structure, the inlet water flow entering the water tank can be effectively prevented from excessive splashing, thereby achieving a significant technical progress in preventing the splashing water flow in the water tank from flowing back into the waterway and obstructing the water outlet of the waterway; the splash-proof structure can also be used to prevent the occurrence of excessive splashing, effectively preventing the washing additive mixture entering the water tank from splashing onto the side wall of the water tank and generating hanging liquid residue.

[0047] In the embodiment of the present invention, the splash-proof structure includes: a water receiving surface 5 inclined downward toward the center of the water tank 1 is provided at the bottom of the water tank 1 below the water outlet 304 of the water channel, and a splash-proof rib 7 extending vertically upward is provided on the water receiving surface 5. By installing the splash-proof rib 7 on the bottom wall of the water tank below the water outlet of the upper cover, the splash-proof rib 7 is used to interfere with the incoming water flow, so that the falling force of the incoming water flow of the water tank 1 is decomposed by the splash-proof rib 7, which effectively reduces the falling speed of the incoming water flow of the water tank, thereby achieving the effect of splash-proofing the incoming water flow in the water tank 1. At the same time, in the present invention, by setting the bottom wall of the water tank below the water outlet of the upper cover water channel as an inclined surface inclined downward toward the center, the incoming water flow of the water tank can flow into the water tank 1 along the inclined surface, effectively avoiding the occurrence of water gathering below the water outlet of the water channel, and further avoiding the generation of splashing water flow in the water tank 1.

By setting the upper end surface of the water-splashing rib 7 as an inclined surface, the water flow falling to the water-splashing rib 7 can flow along the upper end inclined surface, further improving the diversion and buffering effect of the water-splashing rib on the falling inlet water flow, and effectively reducing the splashing water flow in the water storage tank 1.

[0049] In the embodiment of the present invention, the upper surface of the water receiving surface 5 is provided with a plurality of anti-splash ribs 7 arranged in a plurality of rows and columns; the waterproof ribs 7 are arranged at the same height; the upper end surfaces of the waterproof ribs 7 are in the same plane, and the above plane is arranged parallel to the water receiving surface 5. By arranging a plurality of rows and columns of anti-splash ribs in the area below the water outlet of the waterway, the side walls of the anti-splash ribs can be used to interfere with and divert the splashing water flow, thereby reducing the height of the splashing water flow and effectively preventing the generation of excessively high splashing water flow in the water storage tank, which is a significant technical progress.

[0050] Preferably, in the above-mentioned multi-row and multi-column arranged splash-proof ribs 7, the arrangement lines of the same row of splash-proof ribs 7 are staggered at a certain angle with the front and rear directions of the water storage tank 1, so that the staggered arrangement of the splash-proof ribs 7 further enhances the effect of buffering and splash-proofing the incoming water flow in various areas below the water outlet.

[0051] In the embodiment of the present invention, a strip baffle 6 extending vertically upward is provided on the side of the water receiving surface 5 facing the front opening of the water storage tank 1, and the strip baffle 6 is higher than the top height of the anti-splash rib 7. By providing a baffle on one side of the water receiving surface, the water flow entering the water storage tank 1 from the water outlet of the water channel can be blocked by the strip baffle 6 and will not splash toward the water storage tank outlet 101, effectively avoiding the occurrence of the splashing water flow caused by the water inflow hanging on the side wall of the water storage tank, and effectively preventing the generation of residual water in the water storage tank.

[0052] Preferably, the water receiving surface 5 is arranged at a corner of the rear side of the water storage tank 1, and the strip baffle 6 is arranged on the side of the water receiving surface 5 facing the front opening of the water storage tank 1, and one side wall of the strip baffle 6 is in close contact with the corresponding side wall of the water storage tank 1, so that the water receiving surface 5 only uses the side toward the middle of the water storage tank 1 to supply water to flow out. Through the above arrangement, the water inlet area of ​​the waterway is surrounded by the strip baffle 6 and the side wall of the water storage tank on three sides, so that the water flow flowing into the water storage tank 1 can only flow toward the middle of the water storage tank and flow along the bottom wall of the water storage tank to the water storage tank outlet.

By installing a water receiving tray 8 at the water outlet of the water channel and utilizing the hollow chamber provided on the water receiving tray 8 to buffer the water flow of the water channel, the water flow rate can be effectively reduced; at the same time, utilizing the multiple water outlet holes arranged on the water receiving tray 8 to form a shower-like water flow, the water flow can be effectively diverted and the height of the splashing water flow formed in the water storage tank 1 can be greatly reduced, thereby effectively preventing the splashing of the water flow into the water storage tank 1 and causing leakage of the delivery device.
