Description
Technical Field
The invention belongs to the technical field of clothes treatment equipment, particularly relates to an additive feeding device of a washing machine, further relates to the washing machine provided with the additive feeding device, and particularly relates to an additive feeding method applied to the washing machine.
Background
The existing washing machine is generally provided with a water containing barrel for containing washing water, a rotatable washing barrel is arranged in the water containing barrel, and dewatering holes communicated with the inside and the outside are formed in the washing barrel, so that the washing water flowing into the water containing barrel can flow inside and outside the washing barrel in an interactive mode through the dewatering holes, and the effects that the washing water is contacted with a load to be treated in the washing barrel and the load is treated by the washing water are achieved.
The additive feeding mode of the existing washing machine is as follows: the additive is put into a pipeline communicated with a water containing barrel of the washing machine through an additive putting device, and then the put additive flows into the water containing barrel of the washing machine along the pipeline. Therefore, the additives put in the existing mode are positioned in a water containing cylinder and outside a washing cylinder of the washing machine and cannot be directly contacted with a load put in the washing cylinder.
Then, when the washing machine executes the washing program, the thrown additive is mixed with the washing water flowing into the water containing barrel, and part of the washing water mixed with the additive flows into the washing barrel through the dewatering holes and contacts with the load to be processed in the barrel, so that a small part of the additive mixed into the washing water contacts with the load to act on the load. Therefore, the traditional additive feeding mode has the problems of low use efficiency of the fed additive and waste of the additive.
Meanwhile, in the traditional additive feeding mode, in order to ensure that the additive fed between the water containing barrel and the washing barrel is contacted with the load to be treated in the washing barrel, a large amount of water needs to flow into the water containing barrel until the water level of the washing water in the water containing barrel is higher than that of the washing barrel, and the purposes that the washing water flows into the washing barrel through the dewatering holes and the additive is contacted with the load in the washing barrel can be ensured. Therefore, the traditional additive feeding mode has the problem that the water for feeding the additive is excessive.
In addition, the existing additive feeding device is generally provided with a shell forming a water box, and the water box is connected with a water inlet pipe of the washing machine in series; after the additive to be put in flows into the water box through the waterway, when the water inflow of the washing machine flows through the water box, the additive to be put in the water box is flushed out, and the flushed additive to be put in flows into the water containing barrel and out of the washing barrel of the washing machine along with the inflow water, so that the aim of putting the additive is fulfilled.
However, the additive dispensing device of the above structure has problems:
1. the additive needs to flow through the water box for feeding, so that the feeding path of the additive is increased, the residue of the additive in the feeding path is increased, and the actual feeding amount is reduced;
2. the additive flows through the water box and is flushed into the water containing barrel, and the water box has a larger cross section compared with the water channel, so that the flow speed of water flowing through the water box is reduced, and the problems that the additive cannot be flushed in time by water flowing through the water box and the additive is remained in the water box are easily caused.
In view of the above, the present invention is particularly proposed.

Example one
In the embodiment, the additive feeding method of the washing machine is introduced, after the inflow water flow and the fed additive are mixed in the water supply waterway, the mixed liquid is directly sprayed into the rotary washing drum.
As shown in fig. 10, the specific steps of the additive dosing process are as follows,

step S3, water is fed into the water supply waterway at a second set water pressure p2 within a second set time t2, and the fed water and the additive are mixed in the water supply waterway to form a mixed solution containing the additive;
step S4, adjusting the opening of the control valve and/or adjusting the water inflow of the water supply waterway, and in a third set time t3, feeding water at a third set water pressure p3, wherein the mixed liquid flows out from the water outlet of the water supply waterway and is directly sprayed into the washing cylinder through the spray head; the washing drum synchronously rotates around the shaft, so that the mixed liquid is uniformly sprayed to the clothes in the washing drum.
By the control method, the additive mixed liquor is directly and uniformly sprayed to the clothes in the washing drum, so that the clothes to be washed are directly wetted by the mixed liquor, and the water consumption in the washing process is reduced; the additive can be directly and uniformly distributed on the clothes, the use efficiency of the additive is improved, and the loss of the additive is reduced.
In the embodiment, p3 is larger than p 2; t3 is greater than t 2. Therefore, in the process of adding the additive, the water inlet pressure of the water supply waterway is firstly reduced, so that the retention time of the additive in the water supply waterway is slow, and the additive and the inlet water are fully and uniformly mixed; then, after the additive is mixed, the water with larger pressure is supplied to the water supply waterway, so that the mixed liquid is driven by the high-pressure water inlet to be sprayed into the washing drum in a larger coverage range, the coverage area of the additive in the washing drum is increased, and the mixing uniformity of the clothes and the additive is further improved.
In this embodiment, before step S1 is performed, the water is supplied into the water supply path at the first set water pressure p1 for the first set time t1, and the water is flushed from the water supply path. The p1 is greater than p 2; t1 is greater than t 2. Through the arrangement, the water inlet with higher water pressure is supplied to the water supply waterway before the additive is added, so that the additive remained in the water supply waterway can be washed away, and the obstruction to the mixing of the added additive is reduced.
In this embodiment, when step S4 is executed, the mixed liquid is injected into the washing drum from the drum opening of the washing drum, and the washing drum rotates at the set rotation speed V1.
In this embodiment, in the process of executing steps S2 to S4, the washing drum rotates around the shaft at the set rotation speed to stir the clothes in the washing drum, so as to uniformly spray the additive mixture to each part of the clothes in the washing drum.
As shown in fig. 10, the specific process of the washing drum rotation during the additive feeding process is as follows:
while the second set time period t2 of step S3 is being executed, the washing tub is rotated at the set rotation speed V11;
while step S4, a third set time period t3, the washing tub is rotated at the set rotation speed V12;
before executing step S1, when the water is supplied into the water supply waterway for the first set time t1, the washing drum rotates at the set rotation speed V2;
the V12 is greater than or equal to V11, and the V2 is greater than V11.
Example two
The present embodiment is based on the first embodiment, and further has the following technical features:
when the steps S2 to S4 of the first embodiment are executed, the water flowing through the water supply path is alternately executed by the following steps:
step S121, in a first set time period t21, closing a control valve at a water inlet of a water supply waterway, and enabling the water supply waterway not to flow through the water inlet water flow;
and S122, in a second set time period t22, opening a control valve at the water inlet of the water supply waterway, and allowing the inflow water at a second set water pressure p2 to flow in the water supply waterway.
Through throwing in the in-process control at the additive and supplying water the water route interval switching for the additive mixes with the interval rivers that flow through and supply water the water route, further prolongs the retention time of additive in supplying water the water route, promotes the additive and the mixed degree of consistency of rivers that intake in supplying water the water route, and then effectively promotes the mesh of the mixed degree of consistency of throwing in additive and intaking.
In this embodiment, when steps S3 and S4 are executed, the ratio of t21 to t22 is different, so as to utilize the change of the opening and closing time of the water inlet control valve of the water supply waterway, and further achieve the effect of correspondingly adjusting the water pressure of the water supply waterway. Preferably, the ratio of t21 to t22 is n1 when step S3 is executed, and the ratio of t21 to t22 is n2 when step S4 is executed, wherein n1 is greater than n 2.
EXAMPLE III
The present embodiment further has the following technical features based on the first and second embodiments:
in this embodiment, the additive feeding process is divided into a plurality of feeding units, and each feeding unit is sequentially executed according to the steps S1 to S4.

Preferably, T2 is not less than T1, so that a sufficient interval time is kept between each dispensing unit to prevent the occurrence of dispensing interference.
In this embodiment, at the interval t2, the washing drum still rotates around the shaft at the set rotation speed V2 to agitate the clothes in the washing drum, so as to ensure uniform distribution of the clothes in the washing drum and promote uniform contact between the additive and the clothes.
In the embodiment, in each dosing unit, the dosing amount of the additive is not more than the maximum set amount M; preferably, the additive dosage amounts in each dosing unit may be set differently or equally.
For example, as shown in fig. 11, the specific manner of measuring the dosage amount during the additive dosing process is as follows:
step S101, obtaining the total additive amount to be added before the operation program of the washing machine;
step S102, executing a primary putting unit according to the steps S1 to S4;
step S103, when the step S1 of the feeding unit is executed, whether the accumulated additive feeding amount reaches the total additive amount is judged in real time, and if yes, feeding is stopped; if not, continuing to throw in;
