Description

Detergent throwing device and washing equipment

Technical Field

The invention belongs to the technical field of washing equipment, and particularly relates to a detergent throwing device and washing equipment.

Background

In the prior art, the washing machine generally puts in washing liquid, softener and other detergents along with the water inflow in the water inflow process, and the washing agent is directly flushed into the inner barrel of the washing machine by the water inflow. The mode of putting is unfavorable for the thorough mixing of the detergent and the water flow, so that the detergent is not fully dissolved when being put into the inner cylinder, and is quickly deposited to the bottom in the inner cylinder. Especially, in the initial stage of washing, the detergent is not sufficiently dissolved in water, and the washing is started by washing the laundry with water without the addition of the detergent solution, resulting in poor washing effect. After a period of time from the start of washing, most of the detergent can be uniformly distributed in the water along with the rotation of the inner cylinder, so that the detergent is fully contacted with the clothes to remove stains on the clothes. In order to ensure the washing effect, the washing time is required to be prolonged, the whole washing time is prolonged, the energy consumption is increased, and the abrasion degree of clothes is increased.

On the other hand, as the detergent is not fully mixed with the water flow and enters the inner cylinder, part of the solution with higher concentration of the detergent can be directly absorbed by the clothes in the inner cylinder, which is more unfavorable for the subsequent dissolution process of the detergent. In the water inflow process, if the amount of the laundry in the inner tub is large, it may be impossible to wet the entire laundry, and even a part of the laundry is not completely wetted after several minutes from the start of washing, and thus cannot be sufficiently contacted with the detergent. The uneven action of the detergent on the laundry inside the drum results in a lower efficiency of use of the detergent, resulting in wastage of the detergent.

In view of this, the present invention has been made.

Example 1

As shown in fig. 1 to 5, embodiments of the present invention provide a detergent dispensing device, and a laundry appliance, such as a washing machine, including the same. The detergents of this embodiment include, but are not limited to, laundry detergents, softeners, disinfectants, and the like.

Specifically, the detergent dispensing device of the present embodiment includes, in order from top to bottom, a first cover 100, a second cover 200, and a lower case 300. A cavity is formed between the second cover 200 and the lower case 300 for mounting the dispenser box. The dispenser box has a receiving cavity for storing detergent.

The first cover 100 is engaged with the second cover 200 to define a dispensing passage 400 therebetween for a detergent solution. Specifically, the upper surface of the second cover 200 is provided with a convex water blocking rib 210, and the upper edge of the water blocking rib 210 contacts the lower surface of the first cover 100, thereby defining the delivery passage 400.

Further, the lower surface of the first cover 100 may further be provided with a protruding rib corresponding to the water blocking rib 210, and the delivery channel 400 is defined by the contact between the water blocking rib 210 on the second cover 200 and the protruding rib on the first cover 100.

In this embodiment, the dispensing passage 400 has a water inlet 401 for water and a liquid outlet 403 for dispensing a mixed solution of detergent and water to the outside of the detergent dispensing device. An adding port 402 is arranged between the water inlet 401 and the liquid outlet 403, and the adding port 402 is communicated with a containing cavity for storing detergent. A mixing structure for mixing detergent and water is provided between the addition port 402 and the liquid outlet 403 of the dispensing passage 400.

Specifically, the water inlet 401, the adding port 402 and the liquid outlet 403 are all openings disposed on the second cover 200. When the detergent delivery device is installed on the washing equipment, the water inlet 401 is communicated with the water inlet structure of the washing equipment, and an external water source enters the delivery channel 400 from the water inlet. The addition port 402 communicates with a receiving chamber storing the detergent below the second cover 200, sucks the detergent out of the receiving chamber by providing a dosing pump, and puts the detergent into the dosing channel 400 through the addition port 402. The detergent flows along the dispensing passage 400 together with the water flow and is mixed by the mixing structure, so that the detergent is sufficiently mixed with the water before being discharged through the liquid outlet 403.

Through the structure of the detergent feeding device, the detergent can be fed into the washing drum of the washing equipment after being fully and uniformly mixed with water, so that the condition that the detergent is not fully dissolved, namely contacts with clothes and cannot fully act on the clothes is avoided. Therefore, the utilization rate of the detergent is improved, the waste of the detergent is avoided, and the washing effect of clothes can be improved.

In a further aspect of this embodiment, the dispensing channel 400 comprises, in the direction of flow of the liquid therein, a water inlet zone 410, a mixing zone 420 and a dispensing zone 430 connected in sequence, the mixing structure being arranged within the mixing zone 420. The water inlet 401 is arranged at the beginning of the water inlet area 410, and the liquid outlet 403 is arranged at the end of the putting area 430. The beginning end of the mixing area 420 is connected with the end of the water inlet area 410, a certain included angle is formed between the beginning end and the end of the mixing area 420, and the adding port 402 is arranged at the joint of the water inlet area 410 and the mixing area 420.

In the above-mentioned scheme, the water inlet 401 and the adding port 402 are arranged at intervals in the putting channel 400, and the inflow water flow has a certain flow velocity when passing through the water inlet region 410, so that the detergent entering through the adding port 402 has a scouring effect when passing through the adding port 402, and the detergent is forcefully driven to flow to the mixing region 420 together for mixing.

As a preferred embodiment, the tail end of the water inlet area 410 is parallel to and opposite to the start end of the mixing area 420, so that the water flow turns approximately 180 ° when passing through the position of the adding port 402. Thus, the impact force generated by the diversion of the water flow can be utilized to make the detergent be primarily dispersed in the water flow, and further, the fully mixing can be further realized when the primarily mixed solution passes through the mixing structure of the mixing zone 420.

In a further aspect of this embodiment, the width of the dispensing passage 400 at the mixing zone 420 is greater than the width of the dispensing passage at the water inlet zone 410, and the mixing structure is a rib disposed on the second cover 200 and protruding from the inner wall of the mixing zone 420.

In the above scheme, the width of the water inlet area 410 is smaller, wherein the flow velocity of water is relatively high, so that the detergent injected from the adding port 402 can be fully driven to flow to the mixing area 420. The width of the mixing zone 420 is increased compared to the water inlet zone 410, and the liquid is dispersed into the mixing zone 420, which is advantageous for further uniform dispersion of the detergent in the water. The mixing area 420 is provided with a plurality of ribs, and the liquid continuously impacts the ribs and the water retaining ribs 210 on two sides of the mixing area 420 in the flowing process, so that the flowing direction is changed, the dissolution of the detergent can be accelerated, and the mixing effect is enhanced.

In a specific solution of this embodiment, the area provided with the ribs in the mixing area 420 has a certain length along the flow direction of the liquid, and the ribs include a first rib 421, a second rib 422 and a third rib 423 that are sequentially and circularly arranged along the flow direction of the liquid.

Wherein, the first ribs 421 and the second ribs 422 each extend obliquely to the length direction of the mixing region, and the first ribs 421 and the second ribs 422 are each disposed in pairs. The first ribs 421 gradually approach the mixing region 420 from the middle of the mixing region 420 from the right to the left, and the second ribs 422 gradually approach the mixing region 420 from the right to the left from the two sides of the mixing region 420. The third beads 423 extend parallel to the length direction of the mixing section 420 and are disposed near the central axis of the mixing section 420.

In the above scheme, the detergent and water entering the mixing zone 420 pass through the first bead 421, the second bead 422 and the third bead 423 in sequence, and then continue to pass through the first bead 421, the second bead 422 and the third bead 423 of the next period until reaching the end of the mixing zone 420. The liquid flows from right to left in the mixing zone 420, is guided to flow to both sides by the pair of first ribs 421, is guided to be converged to the middle by the pair of second ribs 422, then flows further to the left end along the two side areas of the third ribs 423, reaches the next pair of first ribs 421, and is guided to both sides again. The liquid continuously impinges on the ribs and the side walls of the mixing zone 420 so that the detergent is sufficiently dissolved in the water stream after passing through the mixing zone 420.

In a further aspect of this embodiment, the width of the dispensing passage 400 at the mixing zone 420 is greater than the width thereof at the dispensing zone 430, an angle is formed between the direction of the end of the mixing zone 420 and the direction of the beginning of the dispensing zone 430, and a flow guiding rib 424 for guiding the liquid therein is arranged at the end of the mixing zone 420.

Specifically, the width of the dosing zone 430 is reduced compared to the mixing zone 420, and the flow rate of the mixed detergent solution is increased when it enters the dosing zone 430. At the same time, liquid flows from left to right in the upstream region of the application zone 430 in a direction just opposite to that in the mixing zone 420. The arrangement of the guide ribs 424 guides the liquid to turn downwards, so that the liquid is more easily collected to the initial end of the dispensing zone 430, and the mixed detergent solution can smoothly enter the dispensing zone 430 of the dispensing passage 400 and finally flow out from the liquid outlet 403.

In this embodiment, the dispensing zone 430 of the dispensing passage 400 extends from the end of the mixing zone 420 to the right a certain distance, and then extends to the left a certain distance in the opposite direction, and finally extends downward to the liquid outlet 403. The overall path of the drop zone 430 is long, and the flow path of the detergent in the drop channel 400 is prolonged, so that the detergent which may be insufficiently dissolved may be further dissolved in the course of flowing through the drop zone 430, thereby further enhancing the dissolution uniformity of the detergent.

In a further development of this embodiment, a pressure relief valve 425 is arranged in the mixing zone 420 of the dosing channel 400, which is unidirectionally conducted from the inside to the outside of the dosing channel 400. The pressure release valve 425 is specifically disposed on the second cover 200, and when the water pressure in the delivery channel 400 is higher due to the excessive inflow water, a certain amount of liquid can be discharged to the lower side of the second cover 200 through the pressure release valve 425, so as to reduce the water pressure in the delivery channel 400.

In the above scheme, the pressure release valve 425 can avoid the too high water pressure in the delivery channel 400, and damage the structures of the delivery channel 400 formed by the first cover 100 and the second cover 200. At the same time, the problem of pollution of the detergent caused by water inflow of the accommodating cavity for storing the detergent due to the reverse flow of water flow at the adding port 402 caused by excessive water pressure is avoided.

Further, the side wall of the mixing area 420, that is, the water blocking rib 210 surrounding the mixing area 420 is partially protruded from the inner side to the outer side of the putting channel 400, a concave portion 426 is formed on the inner side of the putting channel 400, and a pressure release valve 425 is disposed in the concave portion 426. In this way, the relief valve 425 is arranged in the edge area of the dosing channel 400, and the outflow of liquid when the relief valve 425 is opened will not affect the overall flow trend of liquid in the dosing channel 400.

Specifically, the width of the start end of the mixing zone 420 is close to that of the water inlet zone 410, and then gradually increases, and the recess 426 is provided in the region where the width is changed. The second cover 200 is provided with a convex flow-dividing rib 427, one end of the flow-dividing rib 427 is located at a position where the width of the mixing area 420 changes, and the extending direction of the flow-dividing rib 427 forms a certain angle with the flowing direction of the liquid at the position. The other end of the diverting bead 427 extends in the direction of the recess 426 in which the relief valve 425 is provided.

In detail, the diverting bead 427 extends entirely in the arc direction. The liquid flows near the position where the width of the mixing zone 420 increases from right to left, and the upper ends of the diverting ribs 427 block part of the liquid, so that the liquid flows along the right side surfaces of the diverting ribs 427 toward the concave parts 426, and finally, the liquid continues to flow rightward bypassing the lower ends of the diverting ribs 427.

In the above-mentioned scheme, the arrangement of the diversion ribs 427 drains to the position of the concave portion 426, so that the concave portion 426 has enough liquid flowing to wash, thereby avoiding the problem that the detergent is accumulated at the concave portion 426 and cannot flow to the area where the ribs are arranged in the mixing area 420, and further ensuring that the detergent delivery device effectively mixes the detergent with the water.

In a further scheme of the embodiment, a balance air valve 411 which is unidirectionally conducted from the outside to the inside of the putting channel 400 is arranged in the water inlet area 410 of the putting channel 400. When the water inlet 401 is not fed at the end of the discharge, a negative pressure environment may be formed in the discharge passage 400 due to the instant water flow cut off, resulting in water failing to flow out of the discharge passage 400. At this time, the balance air valve 411 can be opened under the external atmospheric pressure to balance the internal atmosphere of the dispensing passage 400 with the external atmospheric pressure, so as to avoid water in the dispensing passage 400.

When the above detergent dispensing device is applied to a washing apparatus, such as a drum washing machine, after the washing process is completed in the washing machine and the user opens the door, there is no water in the dispensing passage 400 from the liquid outlet 403, and dripping water may occur to cause complaints of the user.

Further, a buffer rib 412 is disposed between the balance air valve 411 and the adding port 402 in the water inlet area 410, the buffer rib 412 is respectively connected with the water blocking ribs 210 on two sides of the water inlet area 410, and the height of the buffer rib 412 is lower than that of the water blocking ribs 210.

Specifically, the buffer rib 412 is disposed around the side of the balance air valve 411 near the addition port 402. In this way, the upper edge of the buffer rib 412 is not in contact with the upper first cover 100, so that the overall conduction of the water inlet area 410 is not affected. However, when the inflow water flow is cut off and the water flow flowing backwards due to the negative pressure in the delivery channel 400, the buffer ribs 412 can play a certain role in blocking and buffering the flowing backwards, so that the flowing backwards water flow is prevented from passing over the buffer ribs 412 and entering the area where the balance air valve 411 is located. Thus, the balance air valve 411 can be opened quickly under the action of atmospheric pressure, so as to realize the action of balancing air pressure.

In this embodiment, a detergent communication channel 500 is further defined between the first cover 100 and the second cover 200, and the detergent communication channel 500 is isolated from the dispensing channel 400. The detergent communication path 500 has an inlet 501 at one end and an outlet 502 at the other end. The inlet 501 is communicated with a containing cavity which is positioned below the second cover body 200 and stores the detergent, the outlet 502 is communicated with the inlet end of the throwing pump, the outlet end of the throwing pump is communicated with the adding port 402 on the throwing channel 400, and the detergent is thrown into the throwing channel 400.

In the detergent dispensing device of this embodiment, a piston pump is used as a dispensing pump, and when detergent is dispensed, inflow water flows into the dispensing passage 400 through the water inlet 401. The piston pump operates to draw detergent into the detergent communication path 500 from the inlet 501, then into the piston pump from the outlet 502, and finally the piston pump sends detergent into the dosing path through the addition port 402. The detergent entering the putting channel 500 flows to the mixing area 420 under the driving of the water inflow, and is fully mixed with the water through a plurality of ribs arranged in the mixing area 420. The mixed detergent solution flows along the dispensing area 430 and finally flows out of the outlet 403, and can be directly dispensed into the tub of the laundry appliance.

In this embodiment, the detergent delivery device can fully mix the detergent with water and then deliver the mixture, so that the utilization rate of the detergent can be improved, and the problem that the detergent cannot achieve the optimal action effect due to insufficient dissolution of the detergent is avoided. The release valve 425 and the balance air valve 411 are further arranged on the release channel 400 in the detergent release device respectively, wherein the release valve 425 can drain and release pressure when the water pressure in the release channel 400 is overlarge, so that stored detergent is prevented from being polluted by water in a series manner due to countercurrent of water flow, the balance air valve 411 can be communicated with the atmospheric pressure after release is finished, negative pressure water in the release channel 400 is prevented from being stored, and further the problem of water dripping complaint after a user opens a machine door is avoided.
