Description

Technical Field

[0001] The invention relates to the technical field of washing machines, and in particular to a detergent premixing structure for a pulsator washing machine. Background Art

[0002] At present, most fully automatic pulsator washing machines directly pour detergent into the washing tub, and then use water flow to form a mixed liquid with the help of the rotation of the tub, and then contact with the clothes to achieve the purpose of cleaning clothes. However, this detergent adding method has the following problems: 1. After the detergent is added, it is not fully dissolved, and part of the detergent sinks between the inner drum and the outer drum and does not participate in the washing, thereby reducing the degree of cleaning of the clothes and the utilization rate of the detergent to a certain extent; 2. The undissolved detergent or particles are wrapped inside the clothes, which increases the difficulty of rinsing and makes the rinsing effect worse. Summary of the invention

[0003] The object of the present invention is to provide a detergent premixing structure for a pulsator washing machine, which improves the utilization rate of the detergent, thereby improving the cleaning ability and rinsing effect of the fully automatic pulsator washing machine on clothes.

[0004] In order to achieve the above object, the technical solution of the present invention is:

[0005] The present invention discloses a detergent premixing structure for a pulsator washing machine, comprising a detergent box fixed on the washing machine and a drawer installed in the detergent box and used for containing detergent; the detergent box is provided with a water inlet connected to an external water source and a water outlet connected to the inside of the washing machine; the water inlet is provided with a water inlet pipe extending into the upper part of the front end of the drawer; a liquid leakage gap is provided between the rear end of the drawer and the detergent box, and the liquid leakage gap is connected to the water outlet; the rear end of the drawer is provided with a rear panel, and mesh holes are evenly arranged on the rear panel; the mesh holes connect the inside of the drawer with the liquid leakage gap.

[0006] After adopting the above structure, tap water enters the front end of the drawer from the water inlet and flows to the rear end of the drawer. This process flushes the washing liquid at the bottom of the drawer to form a certain mixing effect; the water flow impacts the detergent onto the mesh holes on the rear panel of the drawer. Due to the obstruction of the mesh holes, the flow rate of the detergent is reduced, and the incoming water flows between the mesh holes to achieve full mixing with the detergent; the mixed liquid flows down from the leakage gap after passing through the mesh holes, and then is discharged into the washing machine from the water outlet, realizing the premixing of the detergent, improving the utilization rate of the detergent, and at the same time improving the cleaning ability and rinsing effect of the fully automatic pulsator washing machine for clothes.

[0007] Preferably, the front end of the detergent box is provided with an opening for drawing out or inserting a drawer; the left and right sides of the opening are symmetrically provided with limiting bosses extending from the opening to the rear end of the detergent box; the limiting bosses extend downwardly from the front end of the detergent box to the rear end of the detergent box; the drawer is inserted into the opening from the front to the rear and is supported by the limiting bosses. This arrangement makes it easy to add detergent while avoiding liquid accumulation in the drawer.

[0008] Preferably, the water outlet of the water inlet pipe is a flat structure stretched left and right. Through this design, the water inlet coverage area is guaranteed, thereby ensuring that the water inlet fully dilutes the detergent.

[0009] Preferably, overflow ports are symmetrically arranged above the left and right sides of the rear panel. When the detergent is diluted, foam will be generated, but the foam cannot pass through the mesh, resulting in a large amount of detergent being unable to enter the washing machine. The overflow port design ensures that the foam can pass through the rear panel smoothly.

[0010] Preferably, a liquid cleaning port is provided between the bottom of the rear panel and the bottom plate of the drawer. The liquid cleaning port is designed to prevent residual liquid from being unable to be discharged from the drawer.

[0011] Preferably, the rear panel is an arc-shaped panel that extends in the middle toward the rear end of the drawer and bends on both sides toward the front end of the drawer. The design of the arc-shaped panel can increase the area of ​​the rear panel, making the detergent more dispersed, easier to mix with the water flow, and making the detergent fully dissolved; at the same time, the gathering effect of the left and right sides of the rear panel is improved, shortening the distance from the water flow outlet, and making the water flow impact stronger.

[0012] Preferably, the liquid clearing port is located at the bottom of the middle position of the rear panel. Through this number, it is ensured that the liquid clearing port is located at the lowest position, which is convenient for discharging the remaining accumulated liquid.

[0013] Preferably, a guide plate is provided on the top of the rear panel, which is bent toward the inside of the drawer. The guide plate is designed so that the water flowing down in the drawer plays a reverse diversion role, so that the incoming water forms a tumbling effect in the drawer, which can accelerate the dissolution speed of the detergent and also make the detergent produce more delicate and rich foam.

[0014] Preferably, a stepped mesh structure is fixed on the detergent box at the bottom of the drawer, and the stepped mesh structure includes a middle mesh and side meshes symmetrically arranged on both sides of the middle mesh, the side meshes are higher than the middle mesh and are inclined from the left / right side walls of the detergent box toward the middle mesh; the middle mesh guides the liquid falling from above to the middle mesh. By setting the stepped mesh structure, the undissolved detergent is further blocked for a second time and mixed with the incoming water again under the action of the mesh.

[0015] Preferably, a plurality of diverter plates are evenly installed at the water outlet, and the diverter plates divide the water outlet into a plurality of flow channels. By setting the flow channels, the water collection area of ​​the water outlet is reduced, so that the undissolved detergent is blocked again, and the probability of the incoming water and the detergent contacting is increased.

[0016] After adopting the above technical solution, the beneficial effects of the present invention are:

[0017] The detergent premixing structure of the pulsator washing machine of the present invention solves the technical problem in the prior art that the detergent is directly added to the washing machine, resulting in insufficient dissolution of part of the detergent and low detergent utilization rate. The present invention improves the utilization rate of the detergent, thereby improving the cleaning ability and rinsing effect of the fully automatic pulsator washing machine for clothes.

DETAILED DESCRIPTION

[0025] The present invention will be further described below in conjunction with the accompanying drawings.

[0026] The orientations mentioned in this specification are based on the orientations of the detergent premixing structure of a pulsator washing machine of the present invention when it is working normally, and do not limit the orientations during storage and transportation. They only represent relative positional relationships, not absolute positional relationships.

[0027] Embodiment 1:

[0028] like Figure 1 and Figure 2 As shown together, a detergent premixing structure for a pulsator washing machine includes a detergent box 1 fixed on the washing machine and a drawer 2 installed in the detergent box 1 and used to hold detergent; the detergent box 1 is provided with a water inlet 13 and a water outlet 14; the water inlet 13 can be connected to an external water source to supply water to the detergent box 1, and the water outlet 14 can be connected to the inside of the washing machine to pass water dissolved with detergent into the washing machine. The water inlet 13 is provided with a water inlet pipe 131 extending to the upper front end of the drawer 2; the water inlet pipe 131 extends to the front end of the drawer 2, thereby ensuring that the water inlet position of the water inlet pipe 131 is close to the front end of the drawer 2, and ensuring that the water inlet covers the space in the drawer 2 to the maximum extent, avoiding the problem that the water inlet position is too far back and some detergents cannot be flushed. A leakage gap is provided between the rear end of the drawer 2 and the detergent box 1, and the leakage gap is connected to the water outlet 14; a rear panel 22 is provided at the rear end of the drawer 2, and mesh holes are evenly provided on the rear panel 22; the mesh holes connect the inside of the drawer 2 with the leakage gap.

[0029] In this embodiment, the drawer 2 is installed on the detergent box 1 in a pull-out manner, and the front end of the detergent box 1 is provided with an opening 11 for the drawer 2 to be pulled out or inserted; the drawer 2 includes a bottom plate for supporting detergent, side panels located on the left and right sides of the bottom plate, a rear panel 22 located at the rear end of the bottom plate, and a front panel 21 located at the front end of the bottom plate for closing the opening 11. A handle box 211 is provided on the outside of the front panel 21, and the handle box 211 facilitates the insertion or extraction of the drawer 2. The left and right sides of the opening 11 are symmetrically provided with a limiting boss 12 extending from the opening 11 to the rear end of the detergent box 1, and the drawer 2 is inserted inward from the opening 11 and supported by the limiting boss 12. Further, the limiting boss 12 extends downwardly from the front end of the detergent box 1 to the rear end of the detergent box 1; this setting makes the drawer 2 have a certain installation angle when it is installed, and this installation angle makes the drawer 2 tilt downward from the front to the back, thereby avoiding the situation of liquid accumulation in the drawer 2.

[0030] Furthermore, in order to increase the coverage area of ​​the water outlet of the water inlet pipe 131 in the left-right direction, the water outlet of the water inlet pipe 131 is a flat structure stretched left-right.

[0031] As an improvement of this embodiment, normally, when people pour detergent into the drawer 2, the detergent will accumulate in the middle position of the drawer 2. In order to maximize the impact of the water flow and make the water flow contact with the detergent to the greatest extent, the water inlet 13 is set behind the detergent box 1, and the water outlet position of the water inlet pipe 131 is located in the middle position above the drawer 2.

[0032] Pull the drawer 2 forward and pull it out from the opening 11, then add detergent into the drawer 2; after adding detergent, insert the drawer 2 back into the detergent box 1; inject tap water into the water inlet 13, and the tap water impacts the detergent on the bottom plate to form a certain mixing effect; the water flow impacts the detergent onto the mesh of the rear panel 22, and because of the obstruction of the mesh, the flow rate of the detergent is reduced, and the incoming water flows between the meshes to achieve sufficient mixing; the mixed liquid passes through the mesh and flows down from the leakage gap 31, and then is discharged from the water outlet 14 into the washing machine.

[0033] like Figure 4 As shown, as a further improvement of the rear panel 22 in this embodiment, overflow ports 221 are symmetrically arranged above the left and right sides of the rear panel 22. When the water flow is mixed with the detergent, a certain amount of foam will be generated, but the foam is not easy to pass through the mesh. By symmetrically arranging the overflow ports 221 above the left and right sides of the rear panel 22, the overflow ports 221 will guide the water flow to carry the foam and flow rapidly downward from the left and right sides of the rear panel 22.

[0034] A liquid cleaning port 222 is provided between the bottom of the rear panel 22 and the bottom plate of the drawer 2. The liquid cleaning port 222 can discharge the accumulated liquid at the bottom of the drawer 2 after the washing machine is filled with water. In this embodiment, the liquid cleaning port 222 is preferably provided at the bottom of the middle position of the rear panel 22, because the speed of the water flow is greater than the speed of the detergent during the flow process, and the water hammer pressure at the middle position is relatively large, so the water flow will impact the detergent to both sides, and the detergent will be concentrated on the left and right sides of the drawer 2. The liquid cleaning port 222 is provided at the bottom of the middle position of the rear panel 22 to prevent the detergent from flowing out of the drawer 2 directly from the liquid cleaning port 222.

[0035] A stepped mesh structure 4 is fixed on the detergent box 1 at the bottom of the drawer 2, and the stepped mesh structure 4 includes a middle mesh 41 and side meshes 42 symmetrically arranged on both sides of the middle mesh 41. The side meshes 42 are higher than the middle mesh 41 and are inclined from the left / right side walls of the detergent box 1 toward the middle mesh 41; the middle mesh 41 guides the liquid falling from above to the middle mesh 41.

[0036] like Figure 3 As shown, the detergent will disperse to both sides under the impact of water flow, and the detergent will accumulate on both sides of the front panel 21. Some of the detergent will flow down from the mesh without being mixed and fall onto the side mesh plate 42. The mesh of the side mesh plate 42 will block the detergent for a second time, so that it adheres to it, and then flow to the middle along the side mesh plate 42 under the impact of water flow. During the flow process, it will be diluted by the impact of the water flow from above, and flow to the middle mesh plate 41 under the action of gravity until it is completely diluted. At the same time, by setting the stepped mesh plate structure 4, multiple water flows can be achieved, thereby improving the mixing effect of water flow and detergent.

[0037] A plurality of flow dividers 51 are evenly installed at the water outlet 14, and the flow dividers 51 divide the water outlet 14 into a plurality of flow passages. By dividing the water outlet 14 into a plurality of flow passages, on the one hand, the falling speed of the unmixed detergent is reduced, so that it can collide with the water flow again to achieve mixing; on the other hand, by dividing the water outlet 14 into a plurality of flow passages, the space of the water outlet 14 is reduced, the contact probability of the water flow and the detergent is increased, and the mixing effect is improved.

[0038] Embodiment 2:

[0039] This embodiment improves the rear panel 22 based on the first embodiment. Figure 5 As shown, the rear panel 22 is an arc-shaped plate that extends in the middle toward the rear end of the drawer 2 and bends on both sides toward the front end of the drawer 2. The arrangement of the arc-shaped plate increases the contact area between the rear panel 22 and the detergent. When the detergent adheres to the rear panel 22, it can be more dispersed, which is convenient for mixing with the water flow and making the detergent fully dissolved. At the same time, the gathering effect of the left and right sides of the rear panel 22 is improved, and the distance from the water flow outlet is shortened, so that the impact force of the water flow is stronger.

[0040] Embodiment three:

[0041] This embodiment is further improved on the basis of the second embodiment. Figure 6 As shown, in order to increase the mixing effect of detergent and water, the rear panel 22 is further improved, and a guide plate 223 bent toward the inside of the drawer 2 is provided on the top of the rear panel 22. The guide plate 223 can guide the water flow toward the inside of the drawer 2, so that the water flow forms a rolling state inside the drawer 2, which is conducive to the stirring of the detergent by the water flow, so that the two are evenly mixed, and at the same time, this stirring can accelerate the dissolution speed of the detergent, and can also make the detergent produce more delicate and rich foam.

[0042] The detergent premixing structure of the pulsator washing machine of the present invention solves the technical problem in the prior art that the detergent is directly added to the washing machine, resulting in insufficient dissolution of part of the detergent and low detergent utilization rate. The present invention improves the utilization rate of the detergent, thereby improving the cleaning ability and rinsing effect of the fully automatic pulsator washing machine for clothes.

[0043] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by technicians in this technical field within the essential scope of the present invention should also fall within the protection scope of the present invention.
