Description

Technical Field

[0001] The invention relates to a washing machine in the field of household appliances, and in particular to a water distribution device for the washing machine. Background Art

[0002] With the advancement and development of science and technology, washing machines have become a necessary household appliance for every household. As more and more people use them, there are more and more functional requirements for washing machines. The dispensers of existing washing machines are equipped with water channels due to functional requirements, and the water channels have a restraining effect on water.

[0003] The water path of the existing washing machine dispensing device is fixed by the upper cover and the lower cover to form a closed water path, which forcibly restricts the water flow at the water inlet and forces the water flow to flow in from the opening. The lower cover is evenly provided with a plurality of spray holes, so that water flows out from the spray holes. The spray holes are arranged front and back along the water flow direction to ensure that the detergent in the liquid storage box can be rinsed in all directions. After rinsing, the detergent flows into the sink and then enters the inner drum of the washing machine through the inner hole of the sink. Under this scheme, after the rinsing is completed, some water will not be discharged in the water path. The remaining water will mold and produce odor over time, causing the rinsed detergent to have odor when rinsed again.

[0004] In view of this, the present invention is proposed. Summary of the invention

[0005] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a semi-open water diversion and delivery device, which is only provided with a waterway upper cover and a water diversion and diversion structure. While saving material costs, it avoids the problem of water storage in a closed waterway. The water diversion and diversion structure allows the water to fall freely at different positions during the flushing process, thereby guiding and buffering the water flow, thereby achieving all-round cleaning.

[0006] In order to solve the above technical problems, the basic concept of the technical solution adopted by the present invention is:

[0009] Preferably, the intervals between adjacent water-blocking ribs are the same.

[0010] Furthermore, each water-blocking rib vertically extends downward from the bottom wall of the water tank upper cover, and the height of each water-blocking rib in the vertical direction increases downward from the open end to the closed end.

[0011] Furthermore, the water inlet waterway comprises two parallel and spaced apart restraining ribs extending vertically downward from the bottom wall of the water tank upper cover, one end of the two restraining ribs passes through the end ribs, and the restraining ribs and the end ribs are connected to form a water inlet waterway with one end open and the other end closed; each water-blocking rib is arranged at intervals in the water inlet waterway formed by the gap between the two restraining ribs, and the left and right sides of each water-blocking rib are respectively fixedly connected to the restraining ribs on the corresponding side; the lower end height of each water-blocking rib is higher than the lower side height of the restraining ribs on both sides.

[0012] Furthermore, a water inlet is provided on the upper cover of the water tank, and the water inlet is opened toward the opening ends of the two restraining retaining ribs, and at least a part of the water inlet is higher than the lower end height of any restraining retaining rib.

[0014] Preferably, the guide rib is arranged in an arc shape, and extends from the opening end of the restraining rib to the side of the water inlet to form a curved portion, and the extended axis line of the water inlet intersects with the curved extension portion of the guide rib;

[0015] Further preferably, the end of the curved portion of the guide rib is provided with a straight extension portion parallel to the axis of the water inlet.

[0016] Furthermore, each water-blocking rib provided in the water inlet channel is arranged in an arc shape, and the arc-shaped water-blocking rib is bent toward the opening end of the water inlet channel on a side close to the water inlet.

[0017] Furthermore, the water tank upper cover is provided with three water inlet waterways, namely a first water inlet waterway, a second water inlet waterway and a third water inlet waterway;

[0018] The first water inlet waterway and the second water inlet waterway are symmetrically distributed, and the third water inlet waterway is symmetrical along the midline;

[0019] The center line of the third water inlet waterway coincides with the symmetry lines of the first water inlet waterway and the second water inlet waterway.

[0020] Furthermore, the sink cover is provided with two water inlets, and the two water inlets are symmetrically distributed along the center line of the third water inlet waterway, and the two water inlets are arranged in a V shape; the two water inlets are respectively arranged toward the opening ends of the first water inlet waterway and the second water inlet waterway, so that when water is taken in from the two water inlets separately, water is respectively taken in from the first water inlet waterway and the second water inlet waterway, and when water is taken in from the two water inlets at the same time, water is taken in from the third water inlet waterway.

[0021] Furthermore, the water inlet includes a first water inlet and a second water inlet, the extended axis line of the first water inlet intersects with the curved portion of the guide ribs of the first water inlet waterway, and the extended axis line of the second water inlet intersects with the curved portion of the guide ribs of the second water inlet waterway.

The water-blocking ribs in the water inlet water channel are arranged in increasing order in the vertical length, and the water flow is guided to flow into the delivery chamber in sections. While fully flushing the detergent, the water flow is also restricted in the left and right directions. Multiple water inlets can also meet the needs of fully flushing the detergent in multiple delivery boxes, and water pressure is used to make the water flow to the blocked water inlet waterway.

DETAILED DESCRIPTION

[0035] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention but are not used to limit the scope of the present invention.

[0036] In the description of the present invention, it should be noted that the directions or positional relationships indicated by terms such as “upper”, “lower”, “front”, “back”, “left”, “right”, “vertical”, “inside” and “outside” are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

[0037] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0038] like Figures 1 to 4 As shown, an embodiment of the present invention introduces a dispensing device for a washing machine, including a water tank 3, a top cover 1 is buckled on the top of the water tank, a dispensing box 2 that can be pulled outward is installed in the water tank 3, the dispensing box 2 is provided with at least one dispensing cavity 21, the top cover 1 includes at least one water inlet waterway 11, the water outlet of the water inlet waterway 11 is located on the upper side of the dispensing cavity 21, and the lower side of the water outlet is open; a plurality of water-blocking ribs 14 are provided on the water inlet waterway 11 along the water flow direction, which are used to guide the inlet water flow to flow into the dispensing cavity 21 below.

[0039] Through the design of the above-mentioned open water channel, unlike the existing closed water channel, the closed water channel is formed by splicing an upper cover and a lower cover. The water channel of the present invention only has an upper cover, which saves material costs and eliminates the problem of water accumulation in the closed water channel. The water inlet water channel is arranged on the upper cover, so that the water in the water channel can flow smoothly into the delivery box.

[0040] like Figures 3 to 6 As shown, in this embodiment, the water inlet waterway 11 includes two mutually parallel restraining ribs 13 extending vertically downward from the bottom wall of the water tank upper cover 1, and the same end of the two restraining ribs 13 is connected to the end rib 15. The two restraining ribs 13 and the end rib 15 connect the water inlet waterway 11 with one end closed and the other end open, and the water flows into the water inlet waterway 11 from the opening direction of the water inlet waterway 11. The end rib 15 extends vertically downward from the bottom wall of the water tank upper cover 1, and the extension length makes the water flow blocked and falls when it reaches the end rib 15. The length of the restraining rib 13 extending in the vertical direction is less than the extension length of the end rib 15. At the end close to the end rib 15, the restraining rib 13 gradually extends in the vertical direction until the length of the connection between the restraining rib 13 and the end rib 15 is the same.

[0041] In this embodiment, the water inlet waterway 11 includes a first water inlet waterway 111, a second water inlet waterway 112 and a third water inlet waterway 113. The first water inlet waterway 111 and the second water inlet waterway 112 are symmetrically distributed. The center line of the third water inlet waterway 113 is the symmetry line of the first water inlet waterway 111 and the second water inlet waterway 112. The first water inlet waterway 111 includes an inner restraining rib 131 and an outer restraining rib 132. The horizontal length of the inner restraining rib 131 at the opening of the water inlet waterway 11 is greater than that of the outer restraining rib 132. The inner restraining rib 131 and the outer restraining rib 132 are vertically connected with an end rib 15 at the closed end of the water inlet waterway 11. The third water inlet waterway 113 includes two third inner restraining ribs that are parallel to each other and have the same length. 1131, the third inner restraining rib 1131 is longer than the inner restraining rib 131 on one side of the opening of the water inlet waterway 11, the third restraining rib 1131 is vertically connected to the third end retaining rib 1132 at the closed end of the water inlet waterway 11, the third end retaining rib 1132 extends vertically downward from the bottom wall of the sink cover 1, and the extended length prevents the waterway from falling when it reaches the position of the third end retaining rib 1132, the extended length of the third restraining rib 1131 in the vertical direction is less than the extended length of the third end retaining rib 1132, and when approaching the third end retaining rib 1132, the length of the third restraining rib 1131 in the vertical direction gradually extends until the length of the connection between the third restraining rib 1131 and the third end retaining rib 1132 is the same.

[0042] In this embodiment, a plurality of water-blocking ribs 14 are provided in the water inlet waterway 11 from the opening to the closed end, and both ends of the water-blocking ribs 14 are connected to the constraint ribs 13. The water-blocking ribs 14 are spaced apart from the opening to the closed end of the water inlet waterway 11, and the intervals between adjacent water-blocking ribs 14 are the same. The water-blocking ribs 14 extend vertically downward from the bottom wall of the water tank upper cover, and the height of each water-blocking rib in the vertical direction increases downward from the opening end to the closed end, and the height of the lower end of each water-blocking rib is higher than the lower side height of the constraint ribs on both sides.

[0043] Specifically, the first water inlet waterway 11 and the second water inlet waterway 12 are provided with water-blocking ribs 14, and the water-blocking ribs 14 are arranged in an arc shape, and the arc-shaped water-blocking ribs 14 are bent toward the opening end of the water inlet waterway near the water inlet. The water-blocking ribs include a first rib 141, a second rib 142, a third rib 143, a fourth rib 144 and a fifth rib 145. The first rib 141 is close to the opening of the water inlet waterway 11, and the first rib 141 extends vertically downward from the bottom wall of the sink upper cover 1 to a certain length. The second rib 142 is arranged at a certain distance from the first rib 141 in the direction from the opening of the water inlet waterway 11 to the closed end. The height of the lower end of the second rib 142 is lower than the height of the lower side of the first rib 141, and the second rib 142 is arranged at a certain distance from the first rib 141 in the direction from the opening to the closed end. A third barrier rib 143 is provided at a certain distance from the second barrier rib 142, and the height of the lower end of the third barrier rib 143 is lower than the lower side height of the second barrier rib 142; a fourth barrier rib 144 is provided at a certain distance from the third barrier rib 143 along the direction from the opening to the closed end, and the height of the lower end of the fourth barrier rib 144 is lower than the lower side height of the third barrier rib 143; a fifth barrier rib 145 is provided at a certain distance from the fourth barrier rib 144 along the direction from the opening to the closed end, and the height of the lower end of the fifth barrier rib 145 is lower than the lower side height of the fourth barrier rib 114; an end barrier rib 15 is provided at a certain distance from the fifth barrier rib 145 along the direction from the opening to the closed end, and the height of the lower end of the end barrier rib 15 is lower than the lower side height of the fifth barrier rib 145; and both sides of the water-blocking barrier rib 14 are respectively connected with constraint barriers 13.

[0044] The water-blocking ribs 14 arranged in the above manner block the water flow at the positions where the water-blocking ribs 14 are located, so that the water flow can be blocked and fall down in sequence at different positions. The frontal velocity of the water flow is slowly released and reversed through the arc-shaped water-blocking ribs 14. The water flow is constrained by the constraining ribs 13 on both sides, so that the water flow is controlled to fall within a certain range and will not splash out of the water inlet waterway 11. The water flow is blocked by the end ribs 15 so that it cannot rush out of the water inlet waterway 11.

[0045] like Figure 5 As shown, in this embodiment, the upper cover 1 includes at least one water inlet 4, and the water inlet 4 is used to allow water to flow in. The water inlet 4 is arranged toward the open ends of the two restraining ribs 13, and the water inlet 4 is located on one side of the open end of the water inlet waterway 11. At least a part of the water inlet 4 is higher than the lower end height of any restraining rib 13, and the water flow entering has a certain speed, so that the water flow can pass through the water-blocking ribs 14 in sequence until the end ribs 15.

[0046] Specifically, the water inlet includes a first water inlet 41 and a second water inlet 42, the first water inlet 41 and the second water inlet 42 are symmetrically distributed along the center line of the third water inlet waterway 113, the first water inlet 41 and the second water inlet 42 constitute a V-shaped water inlet, and water flows obliquely toward the water inlet waterway 11, the first water inlet 41 extends obliquely toward the first water inlet waterway 111, and the second water inlet 42 extends obliquely toward the second water inlet waterway 112, the first water inlet waterway 111 and the second water inlet waterway 112 are symmetrically distributed, and the water flows entering the first water inlet waterway 111 and the second water inlet waterway 112 are diverted in the same way. Taking the water flow entering the first water inlet 41 as an example, the water flows from the first water inlet 41 into the first water inlet waterway 113. In the embodiment of the present invention, the water flow through the first water inlet 41 maintains a certain initial velocity. When the water flow flows into the first baffle 141 of the first water inlet waterway 111, the bottom end of the first baffle 141 is between the vertical lengths of the water flow column. The water flow above the bottom end of the first baffle 141 contacts the first baffle 141 and is blocked and scattered around. The water flow scattering range is limited by the action of the constrained baffle 13, so that the blocked water flow falls freely near the first baffle 141. The water flow below the bottom end of the first baffle 141 maintains a certain velocity and continues to pass through the first baffle 141 forward. When the water flow reaches the second baffle 112, the bottom end of the second baffle 142 is between the vertical lengths of the water flow column and is at the bottom end of the second baffle 112. The water flow above contacts the second barrier rib 142 and is blocked and scattered around. The water flow scattering range is limited by the action of the constrained barrier rib 13, so that the blocked water flow falls freely near the second barrier rib 142. The water flow below the bottom end of the second barrier rib 142 maintains a certain speed and continues to pass through the second barrier rib 142 forward. When it reaches the third barrier rib 143, the bottom end of the third barrier rib 143 is between the vertical lengths of the water column. The water flow above the bottom end of the third barrier rib 113 contacts the third barrier rib 143 and is blocked and scattered around. The water flow scattering range is limited by the action of the constrained barrier rib 13, so that the blocked water flow falls freely near the third barrier rib 143. The water flow below the bottom end of the third barrier rib 143 maintains a certain speed. The water flows through the third barrier rib 143 at a certain speed and continues to pass through the fourth barrier rib 143. When the water flows to the fourth barrier rib 144, the bottom end of the fourth barrier rib 144 is between the vertical lengths of the water column. The water flows above the bottom end of the fourth barrier rib 144 are blocked by the fourth barrier rib 144 and scattered around. The water flows are limited in the range of dispersion by the constrained barrier rib 13, so that the blocked water flows fall freely near the fourth barrier rib 144. The water flows below the bottom end of the fourth barrier rib 144 continue to pass through the fourth barrier rib 144 at a certain speed and continue to pass through the fifth barrier rib 144. When the water flows to the fifth barrier rib 145, the bottom end of the fifth barrier rib 145 is between the vertical lengths of the water column. The water flows above the bottom end of the fifth barrier rib 145 are blocked by the fifth barrier rib 145 and scattered around.The constrained baffle 13 limits the range of water flow, so that the blocked water flow falls freely near the fifth baffle 145. The water flow below the bottom of the fifth baffle 145 maintains a certain speed and continues to pass through the fifth baffle 145. When it reaches the end baffle 15, the bottom of the end baffle 15 is lower than the bottom of the water flow column in the vertical direction. The water flow is completely blocked by the end baffle 15 and falls freely. Through this water distribution method, the water in the waterway is prevented from being moldy and producing odor due to water accumulation in the waterway. The water flow in the waterway can also be diverted to the delivery box 2 at different positions for full flushing.

[0047] like Figure 4 and Figure 5 As shown, a guide rib 12 extends outward from the open end of the restraining rib 13 on the side of the water inlet 4 of the water inlet channel 11, and the extended line of the axis of the water inlet 4 intersects with the guide rib 12. The guide rib 12 extends toward the water inlet 4. The guide rib 12 extends in the vertical direction, and the extension length is the same as the length of the restraining rib 13 at the opening of the water inlet channel 11.

[0048] Specifically, the guide rib 12 includes a curved portion 121 and a straight extension portion 122. Taking the first water inlet waterway 111 as an example, the curved portion 121 is connected to the outer constraint rib 132, and extends from the opening end of the outer constraint rib 132 to the first water inlet 41 side. After extending for a certain distance, it continues to extend to the straight extension portion 122 in parallel with the axis extension line of the first water inlet 41, and extends to the entrance of the second water inlet 42 close to the incoming water flow. The whole after connection is connected with the second water inlet waterway 111. 12 and the whole connected with the extended guide rib 12 are symmetrical along the center line of the third water inlet waterway 113. Water flows in through the first water inlet 41, first flows into the straight extension part 122 of the guide rib 12, and then continues to flow into the curved part 121. The direction of the water flow is gradually changed through the curved part 121, so that the water flow flows smoothly into the first water inlet waterway 111. By setting the arc-shaped guide rib 12, the water flow is smoothly introduced into the water inlet waterway 11, avoiding the situation that the water flow collides with the guide rib 12 and flows back, and cannot enter the water inlet waterway 11.

[0049] In this embodiment, water may be passed to the first water inlet 41 and the second water inlet 42 separately according to actual needs, or water may be passed to the first water inlet 41 and the second water inlet 42 simultaneously.

[0050] When water is passed to the first water inlet 41 alone, the water flows along the guide ribs 12 extending from the first water inlet waterway 111 into the first water inlet waterway 111, and passes through the water-blocking ribs 14 of the first water inlet waterway 111, so that the water flows in sections into the delivery box 2; when water is passed to the second water inlet 42 alone, the water flows along the guide ribs 12 extending from the second water inlet waterway 112 into the second water inlet waterway 112, and passes through the water-blocking ribs 14 of the second water inlet waterway 112, so that the water flows in sections into the delivery box 2; when water is passed to the first water inlet 41 and the second water inlet 42 at the same time, the water flows impact each other due to the water pressure and then merge into one water flow and flow into the third water inlet waterway 113, are blocked at the third end rib 1132, and fall into the delivery box 2. The above method can meet different water inlet requirements and flush the delivery chambers 21 at different positions in the delivery box 2.

[0051] like Figure 2 , Figure 7 As shown, in this embodiment, the delivery box 2 includes at least one delivery chamber 21, the bottom of the delivery chamber 21 is inclined upward along the water flow direction, different detergents are placed in the delivery chamber 21, and the position of the delivery chamber 21 corresponds to the water inlet channel 11. Water flows through the water inlet channel 11 and falls into the delivery chamber 21 in sequence to rinse the detergents at different positions.

[0052] Specifically, the delivery chamber 21 includes a first delivery chamber 211, a second delivery chamber 212 and a third delivery chamber 213. The upper side of the first delivery chamber 211 corresponds to the first water inlet waterway 111. The water-blocking ribs 14 of the first water inlet waterway 111 divert the water flow in sections and fall into the first delivery chamber 211 to flush the detergent in the first delivery chamber 211. The upper side of the second delivery chamber 212 corresponds to the second water inlet waterway 112. The water-blocking ribs 14 of the second water inlet waterway 112 divert the water flow in sections and fall into the second delivery chamber 212 to flush the detergent in the second delivery chamber 212. The third delivery chamber 213 corresponds to the third water inlet waterway 113. The third end rib 1132 in the third water inlet waterway 113 blocks the water flow from falling into the third delivery chamber 213 to flush the detergent in the third delivery chamber 213.

[0053] In this embodiment, water flows into the delivery cavity 21 through the water inlet channel 11, washes the detergent in the delivery cavity 21, and then flows into the water tank 3, and enters the inner drum of the washing machine through the drum inlet hole of the water tank.

[0054] The semi-open water inlet channel avoids the problem of water accumulation in the water channel, and the water dividing structure allows the water to fall in sections to ensure the flushing range and effect. The delivery chamber is also arranged to be inclined upward along the direction of water flow to prevent water accumulation in the delivery box. At the same time, because there is no need to set a water channel lower cover, materials are saved and costs are reduced. The water and detergent in the delivery box also flow into the sink, and then into the washing machine through the sink to rinse the laundry.

[0055] The above description is only a preferred embodiment of the present invention, and does not limit the present invention in any form. Although the present invention has been disclosed as a preferred embodiment as above, it is not used to limit the present invention. Any technician familiar with this patent can make some changes or modifications to equivalent embodiments of equivalent changes by using the technical content suggested above without departing from the scope of the technical solution of the present invention.
