A control method of the laundry treating apparatus 100 according to an embodiment of the present invention is described below with reference to fig. 1 to 5.
As shown in fig. 1 to 4, according to a control method of a laundry treating apparatus 100 according to an embodiment of the present invention, the laundry treating apparatus 100 includes: the spray device comprises a shell 10, an outer cylinder 20, an inner cylinder 30 and a spray assembly 40.
Specifically, as shown in fig. 1, the outer cylinder 20 is provided in the housing 10, the inner cylinder 30 is rotatably provided in the outer cylinder 20, and the inner cylinder 30 communicates with the outer cylinder 20. The "communication" described herein may be understood as partial communication between the inner cylinder 30 and the outer cylinder 20, and for example, a through hole (not shown) may be provided on a wall surface (e.g., a bottom wall) of the inner cylinder 30 to communicate with the outer cylinder 20. Therefore, when the inner cylinder 30 and the outer cylinder 20 rotate relatively, water in the inner cylinder 30 can be thrown into the outer cylinder 20 through the through hole.
The spray assembly 40 is provided in the housing 10 to spray water to the inside of the inner cylinder 30, and the water inlet end 430 of the spray assembly 40 communicates with the bottom of the outer cylinder 20. For example, as shown in the example of fig. 1, the lower end (up and down as shown in fig. 1) of the spray assembly 40 is a water inlet end 430 of the spray assembly 40, and the water inlet end 430 is communicated with the bottom of the outer cylinder 20, so that water at the bottom of the outer cylinder 20 can enter the spray assembly 40 from the water inlet end 430 and be sprayed into the inner cylinder 30 through the spray assembly 40.
The clothes processing device 100 has a washing program, and the control method comprises the following steps:
s1: water is injected into at least one of the inner tub 30 and the outer tub 20 to make the water level in the outer tub 20 reach a first water level, and the height of the items to be washed put in the inner tub 30 is higher than the first water level. For example, as shown in the example of fig. 1, when the laundry is washed, water may be supplied into the inner tub 30 or the outer tub 20. The position of the first water level may be at the bottom of the inner cylinder 30 or a lower position. It should be noted that, when the articles to be washed are put into the inner tub 30, the height of the articles to be washed is higher than the height of the first water level. Therefore, the problem of water resource waste caused by soaking the articles to be washed in water in the traditional washing process is solved.
S2: the spraying assembly 40 is started to spray water into the inner cylinder 30 to soak the articles to be washed in the inner cylinder 30 until the water level in the outer cylinder 20 reaches a second water level, which is lower than the first water level, and at this time, the spraying assembly 40 stops spraying water. As shown in fig. 3 and 4, water in the outer cylinder 20 may be sprayed onto the articles to be washed in the inner cylinder 30 through the spraying assembly 40 to spray and wet the articles to be washed. When the water level in the outer cylinder 20 is lowered to the second water level, the spray assembly 40 stops spraying.
S3: the inner barrel 30 is actuated to move. As shown in fig. 3 and 4, when the spray assembly 40 sprays water onto the items to be washed and stops spraying, the inner cylinder 30 is activated to move. The inner cylinder 30 may move in a clockwise rotation manner as shown by arrows in fig. 3 and 4, but the movement manner of the inner cylinder 30 is not limited thereto, and the inner cylinder 30 may also move in a counterclockwise rotation manner or a shaking movement manner up and down and left and right to throw the water sprayed onto the items to be washed into the outer cylinder 20. It can be understood that, due to the water absorption of the items to be washed, when the inner tub 30 moves, the water thrown from the items to be washed into the outer tub 20 does not reach the first water level, i.e., the water level in the outer tub 20 is lower than the first water level.
S4: after the above steps are circulated to rotate the inner cylinder 30, the water level in the outer cylinder 20 reaches the first water level. It should be noted that, after the water thrown from the articles to be washed into the outer cylinder 20 is lower than the first water level, the operation of step S1 is performed again to inject water into the outer cylinder 20 or the inner cylinder 30 until the first water level is reached. When the water level in the outer cylinder 20 reaches the first water level, stopping injecting water into the outer cylinder 20, performing the operation of step S2, starting the spraying assembly 40 to spray water into the inner cylinder 30 to wet the objects to be washed in the inner cylinder 30, when the water level in the outer cylinder 20 is lowered to the second water level, stopping spraying water from the spraying assembly 40, and performing the operation of step S3, starting the inner cylinder 30 to move to throw the water in the objects to be washed into the outer cylinder 20 again.
It can be understood that since the laundry absorbs part of the water when the laundry is sprayed for the first time, more water is thrown out of the laundry than is thrown out of the laundry for the first time after the second spraying. When the steps S1, S2, S3 are repeated, the water thrown from the laundry into the outer tub 20 shows a tendency to increase. The operations of steps S1, S2 and S3 are continuously repeated until the water thrown from the laundry into the outer tub 20 reaches the first water level. At this point, the items to be washed are already in a fully wetted state.
According to the control method of the laundry treating apparatus 100 of the embodiment of the present invention, by repeating the water injection and spraying operations, the laundry can be wetted with a small amount of water in a circulating manner until the laundry is in a completely wetted state, so as to wash the laundry. Therefore, the problem of water resource waste caused by immersing the articles to be washed into water for washing in the traditional washing mode is solved. Correspondingly, the consumption of water is reduced, and the electric quantity consumption in the water injection and washing processes can be reduced, so that electric energy and water resources are saved, and the energy-saving and environment-friendly effects are achieved.
According to some embodiments of the present invention, the bottom of the outer cylinder 20 may be provided with a water receiving groove 210. As shown in fig. 3, a gap may be provided between the bottom wall of the inner cylinder 30 and the bottom wall of the outer cylinder 20, and the water containing groove 210 may be provided on the bottom wall of the outer cylinder 20. This makes it possible to fully utilize the space of the laundry treatment apparatus 100. And the water containing groove 210 is provided on the bottom wall of the outer cylinder 20, so that the first water level is located at the bottom wall of the inner cylinder 30 or at a position lower than the bottom wall of the inner cylinder 30, and the articles to be washed placed in the inner cylinder 30 are higher than the first water level. The articles to be washed in the inner cylinder 30 are washed in a spraying and soaking mode, and water waste is reduced.
Further, the water inlet end 430 of the spray assembly 40 is in communication with the water receiving tank 210. As shown in fig. 4, the water inlet end 430 of the spray assembly 40 may be disposed at the lower end (up and down direction as shown in fig. 4) of the spray assembly 40, and the water inlet end 430 of the spray assembly 40 is in communication with the water receiving tank 210. Therefore, water in the water containing tank 210 can enter the spraying assembly 40 through the water inlet end 430 of the spraying assembly 40 to spray and wash the articles to be washed in the inner cylinder 30.
In some embodiments of the present invention, the laundry treating apparatus 100 may further include a heating assembly 410, and the heating assembly 410 may be provided in the housing 10 to be adapted to heat the water flowing toward the shower assembly 40. Accordingly, by disposing the heating unit 410 inside the cabinet 10, the aesthetic appearance and safety of the laundry treating apparatus 100 may be improved. Moreover, the water flow in the spraying assembly 40 can be heated by arranging the heating assembly 410, so that the dissolving effect of the detergent and the decontamination effect of the articles to be washed can be improved, and the washing quality is improved.
Further, the heating member 410 is located near the middle of the housing 10 and near the side wall of the housing 10, or the heating member 410 is located at the inner bottom of the housing 10. That is, the heating member 410 may be disposed at a position close to the middle of the housing 10 and close to the side wall of the housing 10, for example, as shown in the example of fig. 1 to 4, the heating member 410 is disposed at a position close to the right side wall of the housing 10 (the left-right direction as shown in fig. 1 to 4), and the heating member 410 is located at a middle position of the housing 10 in the up-down direction (the up-down direction as shown in fig. 1 to 4). Therefore, the space between the outer cylinder 20 and the shell 10 can be fully utilized, and the space occupied by the heating assembly 410 is reduced, so that the structure of the clothes treatment device 100 is more compact and reasonable; the heating element 410 may also be disposed at the inner bottom of the housing 10, thereby facilitating the fixed mounting of the heating element 410.
Optionally, as shown in fig. 1-4, the laundry treating apparatus 100 may further include a pump body 420, and the pump body 420 is in communication with the shower assembly 40. As shown in fig. 1 and 4, a pump body 420 is provided inside the housing 10 at a position close to the lower right end (in the up-down, left-right direction shown in fig. 1 and 4) of the housing 10, and the pump body 420 communicates with the shower assembly 40. Thus, a driving force can be provided to circulate the water flow in the shower assembly 40 through the pump body 420 to improve the flow efficiency of the water flow in the shower assembly 40.
According to some embodiments of the present invention, the laundry procedure may be a soaking procedure, a washing procedure, or a rinsing procedure. It should be noted that the process of washing the laundry items of the laundry treating apparatus 100 may include a wetting process, a washing process, a rinsing process and a dehydrating process. The wetting process, the washing process and the rinsing process may be the washing processes of steps S1-S4. Therefore, the same washing program is selected for the articles to be washed in the washing treatment process, so that the design and the control of the internal program of the clothes treatment device are facilitated, and the reduction of the production cost is facilitated.
In some embodiments of the present invention, in the control method, the inner cylinder 30 is activated to move the inner cylinder 30 at the same time as the shower assembly 40 is activated. As shown in fig. 4, the inner cylinder 30 can be simultaneously started while the spraying assembly 40 is started to spray the articles to be washed, the inner cylinder 30 can rotate clockwise as shown by an arrow in fig. 4, and the inner cylinder 30 can also rotate counterclockwise or shake in the up-down direction or the left-right direction. It can be understood that, during the spraying process, the movement of the inner cylinder 30 facilitates the uniform spraying of the items to be washed inside the inner cylinder 30, so that the wetting efficiency of the items to be washed can be improved.
Alternatively, the inner cylinder 30 rotates in the outer cylinder 20, the inner cylinder 30 has a first rotation speed section in which the maximum rotation speed is less than the minimum rotation speed in a second rotation speed section, and the control method is that the inner cylinder 30 rotates first in the first rotation speed section and then in the second rotation speed section. For example, as shown in the example of FIG. 4, the inner barrel 30 may be rotated in a clockwise direction. In the process that the spraying assembly 40 sprays water into the inner cylinder 30 to wet the articles to be washed, the inner cylinder 30 can be in a first rotating speed section, and the inner cylinder 30 rotates at a lower rotating speed so as to uniformly spray the articles to be washed; in-process in need throwing the water in the interior barrel 30 to outer barrel 20, interior barrel 30 can be in the second rotational speed section to improve the rotational speed of interior barrel 30, so that throw the water in the interior barrel 30 to outer barrel 20 in.
Further, when the inner cylinder 30 rotates at the first rotation speed, the rotation time of the inner cylinder 30 is 8-12 min. For example, during the washing of the laundry, the inner cylinder 30 may be rotated in a clockwise direction as shown by an arrow in fig. 4 for 8-12 min. Therefore, the articles to be washed can rotate and wash in the inner cylinder 30 for a sufficient time, which is beneficial to washing the articles to be washed cleanly. In the washing process of the articles to be washed, the inner cylinder 30 can also be washed for 8-12min in a beating mode of up-and-down movement, so that the articles to be washed are washed clean.
Alternatively, when the inner cylinder 30 rotates at the first rotation speed, the rotation time of the inner cylinder 30 is 10 min. Therefore, the user can conveniently grasp the washing time, and other household work can be performed by planning and utilizing the washing time.
In some embodiments of the invention, the first speed range is 35-55 rpm, and the second speed range is 150-250 rpm. Tests prove that when the rotating speed range of the first rotating speed section is controlled to be 35-55 revolutions per minute, the wetting speed of the articles to be washed in the spraying process is improved, and the washing efficiency of the articles to be washed is improved. When the rotating speed range of the second rotating speed section is controlled at 150-250 rpm, the water in the inner cylinder 30 is convenient to be thrown into the outer cylinder 20, thereby improving the washing efficiency.
Optionally, the rotation speed range of the first rotation speed section is 45-55 rpm, and the rotation speed range of the second rotation speed section is 150-250 rpm. It should be noted that, during the washing process of the articles to be washed, the drum 30 can select different rotation speeds in different washing program segments, so that the washing process is more reasonable. For example, the first rotation speed may be controlled in a range of 35-55 rpm during the wetting procedure and in a range of 45-55 rpm during the washing procedure, so that the washing procedure is more rational.
According to some embodiments of the present invention, in the control method, after the above steps are cycled to rotate the inner cylinder 30, when the water level in the outer cylinder 20 reaches the first water level, the inner cylinder 30 rotates in the outer cylinder 20, and the inner cylinder 30 has a third rotation speed section, and the rotation speed range of the third rotation speed section is 800-. For example, when the object to be washed needs to be dehydrated, the inner cylinder rotates at a high speed in the outer cylinder 20, and the rotation speed of the inner cylinder 30 is 800-.
A control method of the laundry treating apparatus 100 according to an embodiment of the present invention is described in detail in one specific embodiment with reference to fig. 1 to 5. It is to be understood that the following description is illustrative only and is not intended to be in any way limiting.
As shown in fig. 1, the laundry treating apparatus 100 includes: the spray device comprises a shell 10, an outer cylinder 20, an inner cylinder 30 and a spray assembly 40. It should be noted that the laundry treatment apparatus 100 may be a washing machine, for example, the laundry treatment apparatus 100 may be a drum washing machine.
As shown in fig. 1, the laundry treating apparatus 100 includes a casing 10, an outer drum 20 disposed in the casing 10, and an inner drum 30 rotatably disposed in the outer drum 20. A gap is formed between the outer cylinder body 20 and the inner cylinder body 30, a water containing groove 210 is arranged at the bottom of the outer cylinder body 20, and a through hole is formed in the inner cylinder body 30 and is communicated with the outer cylinder body 20 and the inner cylinder body 30.
As shown in fig. 1, the lower end (in the up-down direction in fig. 1) of the spray assembly 40 is a water inlet end 430, and the water inlet end 430 is communicated with the water containing groove 210 of the outer cylinder 20. The upper end (in the up-down direction as shown in fig. 1) of the shower assembly 40 extends into the inner cylinder 30. A spray head (not shown) may be disposed at an upper end (in an up-and-down direction as shown in fig. 1) of the spray assembly 40, and water in the water tank 210 may enter the spray assembly 40 from the water inlet end 430 and be sprayed into the inner cylinder 30 through the spray head. A pump body 420 is communicatively coupled to the spray assembly 40 to provide a driving force for the flow of water within the spray assembly 40. A heating assembly 410 is also disposed above the pump body 420 (in the up-down direction as shown in fig. 1), and the heating assembly 410 can heat the water flow in the spraying assembly 40.
The washing program of the laundry treatment apparatus 100 sequentially includes: a wetting process, a washing process, a rinsing process, and a dehydrating process. When washing clothes, firstly, the clothes to be washed and detergent are put into the inner cylinder 30, and the specific operation method of the washing program includes:
s100: and (5) soaking.
S110: water is injected into the water receiving tub 210 to make the water level reach a first water level.
S120: the pump body 420 is activated to pump the water in the water receiving tub 210 into the shower assembly 40 and spray water into the inner drum 30 through the shower assembly 40 to wet the laundry in the inner drum 30. In the spraying and wetting process, the inner cylinder 30 rotates at a rotating speed of 35-55 rpm, so that clothes can be uniformly sprayed, and the clothes wetting speed is improved.
S130: when the water level in the water tank 210 is lowered to the second water level, the pump body 420 stops working, and the spraying assembly 40 stops spraying water.
S140: as shown in FIG. 3 and FIG. 4, when the spraying assembly 40 stops spraying water, the rotation speed of the inner cylinder 30 is increased to 150 and 250 revolutions/min, so as to throw the inner cylinder 30 and part of the water in the clothes into the water containing tank 210.
It can be understood that, due to the water absorption of the laundry, when the inner drum 30 moves, the water thrown from the laundry into the water receiving tub 210 does not reach the first water level, i.e., the water level in the water receiving tub 210 is lower than the first water level.
S150: the above steps (S110-S140) are circulated to make the water level in the water tank 210 reach the first water level after the inner cylinder 30 rotates at 150 revolutions per minute and 250 revolutions per minute.
It should be noted that, after the water thrown from the laundry into the water tank 210 is lower than the first water level, the water tank 210 is filled with water until the water reaches the first water level. When the water level in the water receiving tub 210 reaches the first water level, the water supply to the water receiving tub 210 is stopped, and the operations of steps S110 to S140 are performed. It can be understood that the laundry may absorb a portion when it is first sprayed. Therefore, after the second spraying, more water is thrown from the laundry into the water receiving tub 210 than water is thrown from the laundry into the water receiving tub 210 for the first time. When the steps S110 to S140 are repeated again, the water thrown from the laundry into the water receiving tub 210 shows a tendency to increase. The operations of steps S110 to S140 are continuously repeated until the water thrown from the laundry into the water receiving tub 210 reaches the first water level. At this time, the laundry is already in a completely wetted state.
S200: and (5) washing procedures.
S210: after the wetting of the laundry is completed, a washing process is started. In the washing process, the inner cylinder 30 is rotated at a speed of 45-55 rpm for about 10 minutes to wash the clothes.
