Description

Detergent dispensing device and laundry equipment Technical field

The invention belongs to the technical field of laundry equipment, and specifically relates to a detergent dispensing device and laundry equipment.

Background technique

Washing machines in the prior art generally add laundry detergent, softener and other detergents along with the incoming water flow during the water inlet process, and the detergent is directly flushed into the inner barrel of the washing machine by the incoming water flow. This delivery method is not conducive to the thorough mixing of the detergent and the water flow, causing the detergent to fail to fully dissolve when it is put into the inner cylinder and quickly settle to the bottom in the inner cylinder. Especially in the initial stage of washing, the detergent is not fully dissolved in the water. The initial washing is just to rinse the clothes with water without the blessing of the detergent solution, resulting in poor washing effect. After the washing starts for a period of time, most of the detergent can be evenly distributed in the water as the inner drum rotates, so that it can fully contact the clothes to remove stains on the clothes. In order to ensure the washing effect, it is necessary to extend the washing time, which will prolong the overall washing time, increase energy consumption, and increase the wear and tear of the clothes.

On the other hand, since the detergent enters the inner cylinder without being fully mixed with the water flow, part of the solution with a higher concentration of detergent may be directly absorbed by the clothes in the inner cylinder, which is even more detrimental to the subsequent dissolution process of the detergent. During the water inlet process, if the amount of clothes in the inner drum is large, it may not be able to wet all the clothes, and even some of the clothes may not be completely soaked a few minutes after the start of washing, and thus cannot fully contact with the detergent. The uneven action of detergent on the clothes in the tube results in low detergent utilization efficiency and waste of detergent.

In view of this, the present invention is proposed.

Embodiment 1

As shown in FIGS. 1 to 5 , embodiments of the present invention provide a detergent dispensing device and laundry equipment, such as a washing machine, including the detergent dispensing device. Detergents described in this embodiment include but are not limited to laundry detergent, softener, disinfectant, Poisons, etc.

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

The first cover 100 and the second cover 200 are fastened together, and a delivery channel 400 for detergent solution is defined therebetween. Specifically, the upper surface of the second cover 200 is provided with a raised 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 channel 400 .

Furthermore, the lower surface of the first cover body 100 can also be provided with raised retaining ribs corresponding to the water retaining ribs 210, and the water retaining ribs 210 on the second cover body 200 are in contact with the raised retaining ribs on the first cover body 100. The delivery channel 400 is limited.

In this embodiment, the delivery channel 400 has a water inlet 401 for water inlet and a liquid outlet 403 for delivering a mixed solution of detergent and water to the outside of the detergent delivery device. An adding port 402 is provided between the water inlet 401 and the liquid outlet 403, and the adding port 402 is connected to the accommodating cavity for storing detergent. A mixing structure for mixing detergent and water is provided between the adding port 402 and the liquid outlet 403 of the delivery channel 400 .

Specifically, the water inlet 401 , the adding port 402 and the liquid outlet 403 are all openings provided on the second cover 200 . When the detergent dispensing device is installed on the laundry equipment, the water inlet 401 is connected to the water inlet structure of the laundry equipment, and the external water source enters the dispensing channel 400 through the water inlet. The adding port 402 is connected to an accommodating cavity for storing detergent located below the second cover 200 . A dispensing pump is provided to suck the detergent out of the accommodating cavity, and the detergent is put into the dispensing channel 400 through the adding port 402 . The detergent flows together with the water flow along the delivery channel 400 and is mixed through the mixing structure, thereby ensuring that the detergent is fully mixed with water before it is discharged through the liquid outlet 403 .

Through the above structure of the detergent dispensing device, the detergent can be fully mixed with water before being put into the washing drum of the washing equipment, thereby avoiding the situation where the detergent fails to dissolve fully and contacts the clothes and cannot fully act on the clothes. This improves the utilization rate of detergent, avoids waste of detergent, and improves the washing effect of clothes.

In a further solution of this embodiment, the delivery channel 400 includes a water inlet area 410, a mixing area 420 and a delivery area 430 connected in sequence along the flow direction of the liquid, and the mixing structure is arranged in the mixing area 420. The water inlet 401 is provided at the beginning of the water inlet area 410, and the liquid outlet 403 is provided at the end of the delivery area 430. The starting end of the mixing zone 420 is connected to the tail end of the water inlet zone 410, and there is a certain angle between the directions of the two. The adding port 402 is provided at the connection between the water inlet zone 410 and the mixing zone 420.

In the above solution, the water inlet 401 and the adding port 402 are set at intervals in the delivery channel 400, and the water inlet flows through The water inlet area 410 has a certain flow rate, and when passing through the adding port 402, it has a flushing effect on the detergent entering through the adding port 402, and effectively drives the detergent to flow to the mixing zone 420 for mixing.

As a preferred solution of this embodiment, the end end of the water inlet area 410 is parallel to and opposite to the beginning end of the mixing area 420, so that the water flow turns nearly 180° when passing through the position of the adding port 402. In this way, the impact force generated by the diversion of the water flow can be used to preliminarily disperse the detergent in the water flow, and further complete mixing can be achieved when the initially mixed solution passes through the mixing structure of the mixing zone 420 .

In a further solution of this embodiment, the width of the delivery channel 400 at the mixing area 420 is greater than its width at the water inlet area 410, and the mixing structure is provided on the second cover 200 and protrudes from the inner wall of the mixing area 420. convex ribs.

In the above solution, the width of the water inlet area 410 is relatively small, and the water flow rate is relatively fast, which can fully drive the detergent put into the adding port 402 to flow to the mixing area 420. The width of the mixing zone 420 is larger than that of the water inlet zone 410, and the liquid is dispersed when entering the mixing zone 420, which is conducive to further uniform dispersion of the detergent in the water. A plurality of convex ribs are provided in the mixing zone 420. During the liquid flow process, the liquid continuously impacts the convex ribs and the water retaining ribs 210 on both sides of the mixing zone 420, changing the flow direction, which can accelerate the dissolution of the detergent and enhance the mixing effect.

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

Wherein, the first convex rib 421 and the second convex rib 422 both extend obliquely to the length direction of the mixing zone, and the first convex rib 421 and the second convex rib 422 are respectively arranged in pairs. The first convex rib 421 gradually approaches from the middle of the mixing zone 420 to both sides of the mixing zone 420 from right to left, and the second convex rib 422 gradually approaches from the both sides of the mixing zone 420 to the middle of the mixing zone 420 from right to left. The third rib 423 extends parallel to the length direction of the mixing zone 420 and is disposed close to the central axis of the mixing zone 420 .

In the above scheme, the detergent and water entering the mixing zone 420 pass through the first convex rib 421, the second convex rib 422 and the third convex rib 423 in sequence, and then continue to pass through the first convex rib 421 and the second convex rib 423 in the next cycle. rib 422 and the third convex rib 423 until reaching the end of the mixing zone 420. The liquid flows from right to left in the mixing zone 420. It is first guided to both sides by a pair of first convex ribs 421, then guided to the middle by a pair of second convex ribs 422, and then flows along both sides of the third convex ribs 423. The side area further flows to the left end, reaches the next pair of first ribs 421, and is guided to both sides again. The liquid continuously impacts on each raised rib and the side wall of the mixing zone 420, so that the detergent can be fully dissolved in the water flow after passing through the mixing zone 420.

In a further solution of this embodiment, the width of the delivery channel 400 at the mixing zone 420 is greater than its width at the delivery zone 430. There is a certain angle between the direction of the end of the mixing zone 420 and the direction of the starting end of the delivery zone 430. The mixing zone 420 A guide rib 424 is provided at the end of the tube to guide the liquid therein to divert.

Specifically, the width of the delivery area 430 is smaller than that of the mixing area 420 , and the flow rate of the mixed detergent solution increases when it enters the delivery area 430 . At the same time, the liquid flows from left to right in the upstream area of the dropping area 430, and the flow direction is exactly opposite to that in the mixing area 420. The arrangement of the guide ribs 424 can guide the liquid to turn downward, making it easier to collect towards the starting end of the delivery area 430, so that the mixed detergent solution can smoothly enter the delivery area 430 of the delivery channel 400, and finally exit through the liquid outlet 403 outflow.

In this embodiment, the delivery area 430 of the delivery channel 400 extends from the end of the mixing area 420 to the right for a certain distance, then reversely extends to the left for a certain distance, and finally extends downward to the liquid outlet 403 . The overall path of the delivery area 430 is longer, which prolongs the flow path of the detergent in the delivery channel 400, so that the possible insufficiently dissolved detergent can be further dissolved in the process of flowing through the delivery area 430, thereby further enhancing washing. dissolution uniformity of the agent.

In a further solution of this embodiment, a pressure relief valve 425 is provided in the mixing zone 420 of the delivery channel 400 for one-way communication from the inside of the delivery channel 400 to the outside. The pressure relief valve 425 is specifically arranged on the second cover 200. When the inlet water flow is too large and the water pressure in the delivery channel 400 is high, a certain amount of liquid can be discharged to the bottom of the second cover 200 through the pressure relief valve 425. Thereby reducing the water pressure in the delivery channel 400.

In the above solution, the setting of the pressure relief valve 425 can prevent the water pressure in the delivery channel 400 from being too high and causing damage to the structure of the first cover 100 and the second cover 200 that cooperate to form the delivery channel 400. At the same time, it is also avoided that excessive water pressure causes backflow of water at the adding port 402, which in turn causes water to enter the chamber where the detergent is stored, causing contamination of the detergent.

Further, the side walls of the mixing area 420, that is, the water retaining ribs 210 that surround the mixing area 420 are partially protruding from the inside of the delivery channel 400 to the outside, and a recess 426 is formed inside the delivery channel 400, and a pressure relief valve 425 is provided in the recess. Within 426. In this case, the pressure relief valve 425 is disposed in the edge area of the delivery channel 400. When the pressure relief valve 425 is opened, the outflow of the liquid will not affect the overall flow trend of the liquid in the delivery channel 400.

Specifically, the width of the starting end of the mixing zone 420 is close to the water inlet zone 410, and then the width gradually increases, and the above-mentioned recess 426 is provided in the area where the width changes. The second cover 200 is provided with a raised diverting rib 427. One end of the diverting rib 427 is located at a position where the width changes in the mixing zone 420, and the extending direction of the diverting rib 427 at this position is consistent with the flow direction of the liquid. angle. The other end of the diverting rib 427 extends in the direction of the recess 426 where the pressure relief valve 425 is provided.

In detail, the diverting rib 427 extends along the arc direction as a whole. The liquid flows from right to left at the position where the width of the mixing zone 420 increases, and the upper end of the diverting convex rib 427 blocks part of the liquid, causing the liquid to flow along the right surface of the diverting convex rib 427 toward the concave portion 426, and finally bypasses the diverting convex rib 427. The lower end of rib 427 continues to flow to the right.

In the above solution, the distributing convex ribs 427 are arranged to guide the flow to the position of the recessed portion 426, so that the recessed portion 426 has enough liquid to flow through for flushing, and avoids the accumulation of detergent in the recessed portion 426 and the inability to set the convex ribs into the mixing zone 420. The area flow problem is solved, thereby ensuring the effective mixing of detergent and water by the detergent dispensing device.

In a further solution of this embodiment, a balance air valve 411 is provided in the water inlet area 410 of the delivery channel 400 for one-way communication from the outside of the delivery channel 400 to the inside. When water no longer enters the water inlet 401 at the end of the placement, a negative pressure environment may be formed in the placement channel 400 because the inlet water flow is instantly cut off, resulting in water that cannot flow out of the placement channel 400 . At this time, the balance valve 411 can be opened under external atmospheric pressure to balance the internal and external atmospheric pressures of the delivery channel 400 and avoid water accumulation in the delivery channel 400 .

When the above-described detergent dispensing device is used in laundry equipment, such as a drum washing machine, after the washing machine completes the washing process and the user opens the machine door, the water in the dispensing channel 400 will flow out from the liquid outlet 403 and dripping water will not occur, causing the user to complain. Case.

Further, a buffering convex rib 412 is provided in the water inlet area 410 between the balance air valve 411 and the adding port 402. The buffering convex rib 412 is connected to the water retaining ribs 210 on both sides of the water inlet area 410, and the convexity of the buffering convex rib 412 is The raised height is lower than the raised height of the water retaining rib 210.

Specifically, the buffering ribs 412 are arranged around the side of the balancing air valve 411 close to the adding port 402 . In this case, the upper edge of the buffering rib 412 does not contact the upper first cover 100 and does not affect the overall conduction of the water inlet area 410 . However, when the incoming water flow is cut off and the negative pressure in the delivery channel 400 causes the water flow to flow backward, the buffering ribs 412 can play a certain blocking and buffering role on the backward flow of water, preventing the backward flow of water from crossing the buffering ribs 412 and entering the balance air valve. 411 area. In this way, the balancing air valve 411 can be quickly opened under the action of atmospheric pressure to achieve the function of balancing air pressure.

In this embodiment, a detergent communication channel 500 is also defined between the first cover 100 and the second cover 200 , and the detergent communication channel 500 and the delivery channel 400 are isolated from each other. The detergent communication channel 500 is provided with an inlet 501 at one end and an outlet 502 at the other end. The inlet 501 is connected to the accommodation cavity where detergent is stored under the second cover 200 . The outlet 502 is connected to the inlet end of the delivery pump. The outlet end of the delivery pump is connected to the adding port 402 on the delivery channel 400 . The detergent is added to the delivery channel 400 . agent.

The detergent dispensing device of this embodiment uses a piston pump as the dispensing pump. When the detergent is dispensing, the incoming water flows through the water inlet 401 and enters the dispensing channel 400. The piston pump works, sucking the detergent into the detergent communication channel 500 from the inlet 501, and then into the piston pump through the outlet 502. Finally, the piston pump sends the detergent into the delivery channel through the adding port 402. The detergent that enters the delivery channel 500 flows toward the mixing zone 420 driven by the incoming water flow, and is fully mixed with water through a plurality of ribs provided in the mixing zone 420 . The mixed detergent solution flows along the delivery area 430 and is finally discharged from It flows out from the mouth 403 and can be directly put into the washing drum of the laundry equipment.

In this embodiment, the detergent dispensing device can fully mix the detergent and water before dispensing it, thereby improving the utilization rate of the detergent and avoiding the failure of the detergent to fully dissolve, resulting in the detergent not being able to achieve the best effect. question. The delivery channel 400 in the detergent delivery device is also provided with a pressure relief valve 425 and a balance air valve 411 respectively. The pressure relief valve 425 can drain water and release the pressure when the water pressure in the delivery channel 400 is too high to prevent the backflow of water from causing the stored washing. If there is water contamination in the agent, the balance air valve 411 can be connected to the atmospheric pressure after the delivery is completed to prevent the negative pressure inside the delivery channel 400 from storing water, thus avoiding the problem of dripping complaints after the user opens the machine door.

Embodiment 2

This embodiment provides a method for controlling detergent delivery and washing in the laundry equipment described in the first embodiment, wherein the laundry equipment has an inner tube and an outer tube, and the inner tube is a washing drum.

The detergent dispensing device of the laundry equipment has at least two independent accommodation chambers, which are respectively used to store different types of detergents. As shown in Figures 1 to 5, each accommodation chamber is provided with a corresponding piston pump. By controlling the operation of different piston pumps, the corresponding type of detergent can be put into the delivery channel 400 through the adding port 402, and then fully mixed with water. After mixing, it flows out through the liquid outlet 403 and is put into the inner cylinder of the washing equipment.

The control method described in this embodiment includes the following steps:

S1. The washing equipment is started, water is supplied and detergent is added;

S11. Water enters the washing equipment to the set water level;

S12. The heating device heats up, steam enters the inner cylinder, turns on the drying fan, and circulates high-temperature air in the cylinder to increase the surface temperature and humidity of the clothes;

S13. Detergent 1 is put in. Detergent 1 is fully mixed with water at one time and sprayed multiple times. The inner cylinder rotates between each spray;

S14. After the spraying is completed, water is supplied to the washing water level, and then the washing and/or rinsing procedures are performed. During the washing and/or rinsing processes, the water temperature is maintained;

S2. Enter the cleaning and/or rinsing process;

S3. After the cleaning and/or first rinsing process is completed, detergent 2 is fully mixed with water and then sprayed;

S4. Add water to the set water level and perform softening and washing until the program ends.

Further, heating continues until the end of the entire washing process. In steps S12 and S13, the purpose of heating is to increase the water content. In other steps, the purpose of heating is to maintain the temperature of the washing water. In the above steps, the temperature of generating steam and maintaining the temperature of the washing water are determined by the built-in program of the washing equipment. These temperatures can be a fixed temperature range. It can also be a fixed temperature value; it can also be set by the user based on parameters such as the amount of laundry and the material of the laundry.

In step S11, water is fed through the condensation pipe to a set water level. The set water level just covers the heating device to prevent the heating device from dry burning, and the water level is lower than the surface of the inner cylinder.
