Detailed Description
The present application will be described in further detail with reference to the accompanying drawings and examples.
Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein in the description of the application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.
An embodiment of the present application provides a pressurized water supply apparatus, as shown in fig. 1 to 3, including: a housing 1, wherein a first water inlet 11 for connecting with a water outlet of a detergent box of the washing machine, a second water inlet 12 for connecting with a main water supply pipeline of the washing machine and a water outlet 13 are formed on the housing 1; the inner wall surface of the second water inlet 12 is a molded surface for pressurizing water flow and guiding the pressurized water flow into the housing 1, the inner wall surface of the housing 1 forms a chamber 14 communicating the first water inlet 11 and the second water inlet 12, and the housing 1 forms a diversion section 15 for pressurizing water flow between the chamber 14 and the water outlet 13.
It can be appreciated that based on the pressurized water supply device, the water flow with the detergent introduced by the first water inlet 11 and the pressurized water flow introduced by the second water inlet 12 can be mixed in the chamber 14, and the mixed water flow can be discharged into the barrel of the washing machine from the water outlet 13 after being secondarily pressurized by the diversion section 15, so that the dissolution effect of the detergent can be effectively improved based on the action of the two pressurized water flows, the waste of the detergent is further reduced, and the better cleaning effect is achieved.
It should be noted that the detergent in the detergent box may be at least one of washing products such as washing powder, laundry detergent, softener, bleaching agent, etc., which is not particularly limited in the embodiment of the present application.
For example, the detergent box may be provided at the top of the cabinet of the washing machine, so that a user can easily add detergent into the detergent box. The detergent box can be a box body for single-time detergent feeding, namely, before clothes are washed each time, a user is required to manually add the detergent to be fed into the box body. The detergent box body can also control the box body of the single detergent feeding amount (also called as the box body of the automatic detergent feeding) based on the water feeding amount of the detergent box, namely, a user does not need to manually feed the detergent before washing clothes each time, and the automatic detergent feeding can be realized based on the water feeding control of the detergent box.
Illustratively, the water intake line of the washing machine includes: a main water supply line and an auxiliary water supply line for supplying water to the detergent box. The washing machine may control the on states of the main water supply line and the auxiliary water supply line based on the valve body, for example, the main water supply line and the auxiliary water supply line may share one reversing valve (e.g., a three-way reversing valve), or the main water supply line and the auxiliary water supply line may be provided with one switching valve, respectively.
It will be appreciated that the water supplied by the main water supply line and the auxiliary water supply line may each be tap water. After the water supplied by the auxiliary water supply pipeline enters the detergent box, the water drives the detergent in the detergent box to be mixed with the detergent box and then enters the first water inlet 11. Here, the first water inlet 11 may be directly connected to the outlet of the detergent box or connected to the outlet of the detergent box through a pipe, which is not limited in the embodiment of the present application.
Illustratively, the second inlet 12 tapers in caliber in a direction from the exterior of the chamber 14 to the interior of the chamber 14.
It will be appreciated that after the tap water supplied from the main water supply line enters the second water inlet 12, the aperture of the second water inlet is gradually reduced along the direction of water flow, so that the water supplied from the main water supply line enters the chamber 14 after being pressurized, and is mixed with the water flow with the detergent (i.e. the water flow introduced from the first water inlet 11) in the chamber 14, so that the dissolution efficiency of the detergent can be increased in the chamber 14.
Illustratively, the second water inlet 12 is located within the chamber 14 at a spaced distance from the end 12A of the inducer 15.
It will be appreciated that due to the reasonable distance between the end 12A of the second inlet 12 and the deflector segment 15, a better mixing of the pressurized water flow introduced from the second inlet 12 with the water flow with detergent introduced from the first inlet 11 is ensured, thus increasing the dissolution efficiency of the detergent.
Illustratively, the deflector segment 15 tapers in caliber in the direction from the chamber 14 to the water outlet 13.
It can be understood that the mixed water in the chamber 14 flows through the flow guiding section 15 to the water outlet 13, and the caliber of the flow guiding section 15 in the direction of flowing in the water flow is gradually reduced, so that the mixed water flow can be secondarily pressurized in the flow guiding section 15, and the secondarily pressurized water flow is discharged through the water outlet 13. The secondary pressurizing structure can further increase the dissolution efficiency of the detergent.
Illustratively, the chamber 14 may be substantially cylindrical, and the flow guiding section 15 may be substantially conical, and the shape of the housing 1 is not particularly limited in this embodiment of the present application.
In some embodiments, the pressurized water supply apparatus further comprises:
a spray pipe and a nozzle (not shown in the figure), the spray pipe is connected with the water outlet 13 and the nozzle, and the nozzle is used for spraying the water flow in the spray pipe into the barrel body of the washing machine.
For example, in the case of a drum washing machine, the nozzle may be disposed at a position toward the central region of the tub such that the nozzle sprays water flow to the central region of the tub, thereby effectively preventing detergent from being difficult to be sufficiently dissolved due to the water flow mixed with the detergent stagnating at the bottom of the tub, etc.
Based on the foregoing pressurized water supply device, an embodiment of the present application provides a control method of a washing machine including the foregoing pressurized water supply device, as shown in fig. 4, the method including:
step 401, controlling the auxiliary water supply line of the washing machine and the main water supply line of the washing machine to alternately supply water for at least one cycle.
Here, the auxiliary water supply line is used to supply water to the detergent box of the washing machine, and in the circulation period, the auxiliary water supply line supplies water for a first period of time before the main water supply line supplies water for a second period of time.
It will be appreciated that the auxiliary water supply line supplies water first, so that a predetermined amount of detergent can be brought into the chamber 14, and then the supply of water to the auxiliary water supply line is stopped, and the main water supply line supplies water, so that the dissolution of the detergent in the chamber 14 is accelerated by the pressurized water flow brought in by the second water inlet 12, and the pressurized water flow can be further pressurized by the second pressurization of the diversion section 15, thereby further improving the dissolution effect of the detergent.
Illustratively, during the cycle period, the method further comprises:
controlling the tub of the washing machine to rotate at a first rotation speed less than a critical rotation speed for a third period of time;
the critical rotation speed is the rotation speed which enables clothes to cling to the inner wall of the barrel body and rotate along with the barrel body.
Here, the third duration may be less than or equal to the duration of the cycle period. It will be appreciated that controlling the tub to rotate at a first rotational speed, for example, at 60rpm (revolutions per minute), during the circulation period may cause the water flow output from the pressurized water supply to be sprayed onto the laundry in the tub and uniformly wet the laundry.
In some embodiments, after each cycle period, the method further comprises:
and controlling the tub of the washing machine to rotate at a second rotation speed greater than the critical rotation speed for a fourth period of time.
Assuming that the washing machine needs to operate for one cycle, after the cycle, the tub of the washing machine is controlled to rotate at a second rotational speed greater than the critical rotational speed for a fourth period of time. If the washing machine needs to operate for a plurality of cycle periods, after each cycle period, the tub of the washing machine is controlled to rotate for a fourth period of time at a second rotational speed greater than the critical rotational speed.
It can be understood that after each cycle, the tub is controlled to rotate at the second rotation speed, so that the wetted laundry and the attached detergent can be thrown to a state of being closely attached to the wall surface of the tub under the action of centrifugal force, thereby increasing friction between the detergent and the laundry and further increasing dissolution efficiency of the detergent.
It should be noted that, for the case that the washing machine operates for a plurality of cycle periods, it can be understood that the detergent in the detergent box needs to be put in for a plurality of times, and after each time of putting in, the barrel body can be controlled to rotate at the second rotation speed based on the above control, so that friction between the detergent and the clothes is increased, and further dissolution efficiency of the detergent is increased, so that the detergent in the barrel body is fully dissolved.
In some embodiments, the method further comprises:
determining the execution times of the cycle based on the load amount of the laundry in the tub;
wherein the number of executions increases with an increase in the load amount.
For example, the washing machine may acquire a load amount of the laundry in the general body, the load amount may be a weight of the laundry or a volume of the laundry, determine a load level based on the acquired load amount, for example, determine a load level corresponding to a current load amount based on a mapping relationship between the load amount and the load level, and determine the number of times of execution of the cycle period based on the load level.
In an application example, the load level is divided into a small load, a medium load and a large load, wherein the execution times of the cycle periods corresponding to the small load are one time, the execution times of the cycle periods corresponding to the medium load are two times, and the execution times of the cycle periods corresponding to the large load are three times. Those skilled in the art can reasonably set the device according to the needs, and the embodiment of the application is not particularly limited.
In some embodiments, before controlling the auxiliary water supply line of the washing machine and the main water supply line of the washing machine to alternately supply water for at least one cycle, the method further comprises:
the main water supply pipeline is controlled to supply water so that the clothes in the barrel body of the washing machine are wet.
Here, the water supply amount controlling the main water supply line to supply water may be determined based on the amount of laundry in the tub. I.e., a period of time during which the main water supply line supplies water, before the aforementioned cycle is performed, may be controlled based on the amount of load of laundry.
For example, in order to enable the laundry in the tub to be uniformly wetted, the tub may be further controlled to rotate at a rotation speed less than the critical rotation speed during the control of the water supply of the main water supply line.
In some embodiments, after controlling the auxiliary water supply line of the washing machine and the main water supply line of the washing machine to alternately supply water for at least one cycle, the method further comprises:
and controlling the main water supply pipeline and/or the auxiliary water supply pipeline to continuously supply water until the water level in the barrel body of the washing machine reaches the target water level.
For example, if the detergent box is a box body for single-time detergent feeding, after the washing machine performs the cycle, that is, after the control of feeding water of the detergent is performed, the main water supply pipeline and the auxiliary water supply pipeline can be controlled to continuously supply water until the water level in the tub reaches the target water level, so that the water feeding time of the water fed in the tub can be shortened, and the washing efficiency can be improved.
If the detergent box is a box body for automatically putting the detergent, the main water supply pipeline can be controlled to continue supplying water until the water level in the barrel body reaches the target water level after the washing machine executes the cycle.
For example, the target water level may be determined by the washing machine based on the load amount of laundry, thereby omitting the troublesome operation caused by the user setting.
It can be appreciated that in the process of replenishing water to a target water level in the tub, the tub can be controlled to rotate, for example, the tub of the washing machine is controlled to rotate based on a set beat, so that the detergent in the tub is sufficiently dissolved, and the washing efficiency can be improved.
The application is described in further detail below in connection with an application example.
The washing machine includes: the pressurized water supply device of the embodiment of the application comprises a water supply pipeline of a washing machine, wherein the water supply pipeline comprises: the water supply device comprises a main water supply pipeline and an auxiliary water supply pipeline for supplying water to the detergent box, wherein a first water inlet of the pressurized water supply device is connected with a water outlet of the detergent box, a second water inlet of the pressurized water supply device is connected with the main water supply pipeline, a water outflow port of the pressurized water supply device is connected with a nozzle through a spray pipeline, and a nozzle is used for spraying water flow in the spray pipeline into a barrel body of the washing machine.
As shown in fig. 5, the control method of the washing machine of the present application example includes the steps of:
step 501, laundry is weighed.
Here, the washing machine may determine the weight of laundry in the tub based on fuzzy weighing, resulting in a weighing result.
Step 502, judging the distribution condition of the clothes in the barrel body based on the weighing result.
Here, the washing machine may judge the distribution of laundry in the tub based on the weighing result.
For example, the load level corresponding to the current load amount may be determined based on a mapping relationship between a preset load amount and the load level. As shown in fig. 5, if it is determined that the distribution of the laundry is a small load based on the current weighing result, steps 503 to 506 are performed; if it is determined that the distribution condition of the laundry is the medium load based on the current weighing result, executing steps 507 to 510; if it is determined that the laundry distribution is a heavy load based on the current weighing result, steps 511 to 514 are performed.
For small loads, the process of executing steps 503 to 506 is as follows:
and step 503, controlling the main water supply pipeline to supply water for 15 seconds, and controlling the barrel body to rotate for 12 seconds and stop rotating for 3 seconds at the rotating speed of 60rpm during the water supply process.
Illustratively, the original state of the laundry in the tub is shown in fig. 6A before water is supplied.
