Detailed Description
Reference will now be made in detail to embodiments of the present application, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below by referring to the drawings are exemplary only for the purpose of explaining the embodiments of the present application, and are not to be construed as limiting the embodiments of the present application.
Referring to fig. 1 to 3, the present disclosure provides a cleaning apparatus 100, including: a wash tank 10, a pulsator assembly 20, a fluid inlet assembly 30, and a fluid extraction assembly. The washing container 10 is provided with an accommodating space 11, and the pulsator assembly 20 is disposed in the accommodating space 11. The fluid inlet assembly 30 is installed at the washing container 10, and communicates the outside with the receiving space 11 through the pulsator assembly 20. The fluid extraction assembly is connected to the washing container 10, and is configured to extract fluid in the accommodating space 11, so that external fluid enters the pulsator assembly 20 through the fluid inlet assembly 30 to drive the pulsator assembly 20 to rotate.
The cleaning apparatus 100 extracts the fluid in the accommodating space 11 through the fluid extraction assembly, so that a negative pressure is formed in the accommodating space 11, and the external fluid can enter the impeller assembly 20 through the fluid inlet assembly 30 under the action of the negative pressure, so as to drive the impeller assembly 20 to rotate at a high speed through the flow of the external fluid. In the case that the liquid is contained in the containing space 11, when the fluid enters the containing space 11 through the impeller 22 rotating at a high speed, the fluid impacts the liquid in the containing space 11 to generate a large amount of air bubbles, and the air bubbles are broken when contacting an object to be cleaned to generate oscillation, so that the dirt on the object to be cleaned is peeled off through the oscillation. In this way, the washing container 10 of the cleaning apparatus 100 does not rotate, and the cleaning apparatus 100 does not shake violently while operating, so as to prevent damage to the object to be cleaned due to the violent shaking. The cleaning apparatus 100 does not rely on friction between the pulsator 22 and the object to be cleaned when the pulsator 22 rotates to clean the dirt, and can prevent the object to be cleaned from being damaged by a large friction force.
The object to be cleaned may include clothes, shoes, cloth, towels, etc., which are not listed here.
Referring to fig. 1 and 2, in some embodiments, the cleaning apparatus 100 further includes a cover plate 90, an upper sleeve 81, and a lower sleeve 82. The upper sleeve 81 and the lower sleeve 82 are combined to form a sleeve which is sleeved outside the washing container 10 to protect the washing container 10. The cover plate 90 is connected with the upper sleeve 81 to close the upper portion of the receiving space 11 of the washing container 10.
In some embodiments, the cover plate 90 may be detached from the upper sleeve 81 to inject liquid into the housing space 11.
Referring to fig. 1-3, the washing container 10 includes opposite first and second ends 12 and 13, a fluid inlet assembly 30 disposed at the first end 12, and a fluid extraction assembly disposed at the second end 13. As shown in fig. 1 and fig. 3, the first end 12 and the second end 13 opposite to each other specifically refer to: the portion of first end 12 that is below the centerline 14 of wash vessel 10 and the portion of second end 13 that is above the centerline 14 of wash vessel 10 are not limited to being directly above and below wash vessel 10. For example, the washing container 10 includes a top wall 15, a bottom wall 16, and a side wall 17 connecting the top wall 15 and the bottom wall 16. In the embodiment illustrated in fig. 1, the first end 12 is a bottom wall 16, the fluid intake assembly 30 is disposed on the bottom wall 16, the second end 13 is a top wall 15, and the fluid extraction assembly is disposed on the top wall 15. In this way, the flow path of the fluid in the washing container 10 is simple, and the efficiency of pumping the fluid is high. In the embodiment illustrated in fig. 3, the first end 12 is the side wall 17 adjacent the bottom wall 16, the fluid intake assembly 30 is disposed on the side wall 17, the second end 13 is the top wall 15, and the fluid extraction assembly is disposed on the top wall 15. Thus, the external fluid can be introduced into the accommodating space 11 from the position of the side wall 17, so that the bottom wall 16 can be close to the ground, and the size of the cleaning device 100 in the height direction can be reduced. In other embodiments, the second end 13 may be a position of the side wall 17 near the top wall 15, and the fluid extraction assembly is disposed on the side wall 17, so that the cleaning device 100 can guide the fluid in the receiving space 11 out of the side wall 17.
Referring to fig. 1 and 4, in some embodiments, the pulsator assembly 20 is provided with a flow passage 21 communicated with the accommodating space 11, and the external fluid enters the accommodating space 11 through the flow passage 21. Fluid inlet assembly 30 includes an inlet conduit 32, and inlet conduit 32 extends through first end 12 of wash vessel 10 and communicates with the inlet of flow passage 21 to allow external fluid to flow into flow passage 21 through inlet conduit 32.
Referring to fig. 1, 2 and 4, in some embodiments, the pulsator assembly 20 includes a pulsator 22 and blades 23 disposed on the pulsator 22. During the rotation of the blades 23 with the pulsator 22, the blades 23 rotate the liquid in the washing tub 10 to form a turbulent flow. The liquid in the conventional pulsator washing machine does not flow in a turbulent flow manner, and a stable saturated layer is formed on the surface of the object to be cleaned when the flowing liquid contacts the object to be cleaned, so that the stain is difficult to be separated from the object to be cleaned. When the turbulent flow contacts with the object to be cleaned, a stable saturated layer cannot be formed on the surface of the object to be cleaned, so that stains are easily dissolved in liquid under the cleaning of the turbulent flow and are separated from the object to be cleaned, the cleaning effect is enhanced, and the cleaning time is shortened.
Referring to fig. 4, in some embodiments, the vane 23 includes a top surface 231 and a side surface 232, the inside of the vane 23 is communicated with the flow channel 21, and the outlet 211 of the flow channel 21 is opened at the side surface of the vane 23. Under the action of negative pressure, the fluid in the flow channel 21 enters the accommodating space 11 from the outlet 211 and drives the impeller 22 to make circular motion, and the exit direction of the fluid is the tangential direction of the rotation of the impeller 22 making circular motion.
Referring to fig. 1, in some embodiments, the inner diameter of the wash vessel 10 increases from the side near the fluid intake assembly 30 to the side near the fluid extraction assembly. For example, in the embodiment illustrated in FIG. 1, the inner diameter of the wash vessel 10 increases from the bottom-up assembly. The side of the wash vessel 10 adjacent the fluid extraction assembly has a larger internal diameter and the side adjacent the fluid entry assembly 30 has a smaller internal diameter, i.e., the outlet aperture of fluid exiting the wash vessel 10 is larger than the inlet aperture of fluid entering the wash vessel 10. Thus, the flow rate of the fluid in the washing container 10 can be increased, and the fluid flow efficiency in the washing container 10 can be improved, including the efficiency of the fluid entering the washing container 10 and the efficiency of the fluid being extracted from the washing container 10, thereby improving the cleaning efficiency.
Referring to fig. 3, in some embodiments, the fluid extraction assembly includes an extraction unit 42 disposed outside the housing space 11, a power unit 43 disposed outside the housing space 11, and an extraction conduit 44. Depending on the type of fluid, the extraction unit 42 may be a suction pump, etc. The power unit 43 includes a motor, and the power unit 43 is connected to the extraction unit 42 and is configured to power the extraction unit 42. The extraction pipe 44 penetrates through the second end 13 of the washing container 10 and is used for communicating the extraction unit 42 and the accommodating space 11, and the fluid in the accommodating space 11 is extracted into the extraction pipe 44 under the action of the extraction unit 42 so as to extract the fluid in the accommodating space 11.
Referring to fig. 5, the present disclosure provides a washing control method of a cleaning apparatus 100, including:
01: opening the fluid inlet assembly 30 installed in the washing container 10, so that the external fluid can enter the accommodating space 11 of the washing container 10 through the fluid inlet assembly 30 and the pulsator assembly 20;
02: the fluid extraction assembly extracts fluid from the accommodating space 11, so that the external fluid enters the impeller assembly 20 through the fluid inlet assembly 30 to drive the impeller assembly 20 to rotate; and
03: the washing liquid in the accommodating space 11 is driven by the rotation of the pulsator assembly 20 to wash the clothes in the accommodating space 11.
Referring to FIG. 3, in some embodiments, the cleaning device includes one or more processors 88, memory 89, and one or more programs. The one or more programs are stored in the memory 89 and executed by the one or more processors 88. The program includes instructions for executing the washing control method of 01, 02, 03.
Referring to fig. 3, in some embodiments, the cleaning device further comprises a control box 87, and the control box 87 is provided with one or more control keys 871. The control key 871 is used to trigger instructions for executing the washing control methods of 01, 02, and 03.
In some embodiments, the control keys 871 include a first key, a second key, and a third key. The first button is used for triggering the instruction of executing the washing control method of 01, the second button is used for triggering the instruction of executing the washing control method of 02, and the third button is used for triggering the instruction of executing the washing control method of 03.
For example, the first button is an "air intake" button, and the user can press the first button to activate the fluid inlet assembly 30, so that the external fluid enters the receiving space 11 of the washing container 10 through the fluid inlet assembly 30 and the pulsator assembly 20 via the fluid inlet assembly 30. Wherein the external fluid refers to a fluid outside the cleaning apparatus 100. The fluid may comprise a gas or a liquid. The second button is an air extraction button, and a user can press the second button to start the fluid extraction assembly to extract the fluid in the accommodating space 11 through the fluid extraction assembly, so that the inside of the accommodating space 11 is kept in a negative pressure state. The third key is a 'rotating speed' key and comprises a plurality of third sub-keys, and each third sub-key corresponds to one rotating speed gear. The pulsator assembly 20 is driven to rotate by the fluid when the fluid enters the receiving space 11, and the third button can control the amount of air taken by the fluid in the pulsator assembly 20 into the receiving space 11 to adjust the rotation speed of the pulsator assembly 20. The larger the intake air amount, the faster the rotation speed of the pulsator assembly 20.
In one embodiment, the ambient fluid is a gas and the fluid intake assembly 30 is in communication with the atmosphere. After the user presses the first button, the fluid inlet assembly 30 is turned on to operate, so that external air can enter the pulsator. The washing container 10 is filled with a cleaning solution in which washing powder or washing substances such as laundry detergent are dissolved. After the fluid inlet assembly 30 is opened to work, the external air enters the accommodating space 11 under the negative pressure of the accommodating space 11, and impacts the cleaning fluid to generate bubbles, so that the dirt on the object to be cleaned is peeled off through the oscillation of the broken bubbles. When the air is sucked into the accommodating space 11, the impeller is driven to rotate, so that the impeller stirs the cleaning liquid in the accommodating space 11 to form turbulent flow, when the turbulent flow is contacted with the object to be cleaned, a stable saturated layer cannot be formed on the surface of the object to be cleaned, so that stains are easily dissolved in the liquid under the washing of the turbulent flow to be separated from the object to be cleaned, the cleaning effect is enhanced, and the cleaning time is shortened.
In yet another embodiment, the ambient fluid is a liquid and the fluid intake assembly 30 is in communication with an external supply tank. For example, the liquid is a cleaning liquid, and when the fluid inlet assembly 30 is turned on, the cleaning liquid flows through the fluid inlet assembly 30 and the pulsator assembly 20 into the accommodating space 11, so as to inject the cleaning liquid into the accommodating space 11. The pulsator assembly 20 rotates by the cleaning liquid and agitates the cleaning liquid existing in the receiving space 11 to form a turbulent flow. When the fluid extraction assembly is turned on, the fluid extraction assembly extracts the cleaning fluid in the accommodating space 11 to maintain the negative pressure in the accommodating space 11. When a certain amount of the cleaning liquid has been injected into the accommodating space 11, the cleaning liquid entering the accommodating space 11 from the pulsator assembly 20 collides with the existing cleaning liquid in the accommodating space 11 to generate bubbles.
In some embodiments, the control keys include a fourth key, which is an "auto" key for triggering an instruction to perform the washing control method of 01, 02, 03. After the user presses the fourth button, the cleaning apparatus automatically controls the fluid inlet assembly 30 to input the fluid into the accommodating space 11, the fluid extraction assembly to extract the fluid in the accommodating space 11, and the rotation of the pulsator assembly 20.
According to the washing control method, the fluid is input into the accommodating space 11 through the fluid inlet control assembly 30, and the fluid in the accommodating space 11 is extracted through the fluid extraction assembly, so that the impeller assembly 20 is driven to rotate, the impeller assembly 20 is not directly driven to rotate through the control driving device, friction generated by the impeller assembly 20 on an object to be cleaned can be reduced, and the object to be cleaned is prevented from being damaged.
Referring to fig. 5 and 6, in some embodiments, 02: the fluid extraction from the receiving space 11 by the fluid extraction assembly comprises:
021: during washing, the fluid extraction assembly is continuously operated to extract fluid from the receiving space 11.
Referring to fig. 3, in some embodiments, the program further includes instructions for executing the washing control method of 021.
Referring to fig. 3, in some embodiments, the control button is further used to trigger an instruction for executing the washing control method 021.
Referring to fig. 1, in some embodiments, the fluid extraction assembly extracts fluid from the receiving space 11 by an amount greater than or equal to the amount of fluid entering the receiving space 11. Before washing, the fluid extraction assembly is operated to extract the receiving space 11 into a negative pressure state. During washing, the fluid extraction assembly is continuously operated to extract the fluid in the receiving space 11, so as to ensure that the receiving space 11 is always maintained at a negative pressure. While continuing to open fluid into the assembly 30 to continue to generate bubbles and turbulence.
In certain embodiments, the fluid extraction assembly extracts less fluid from the receiving space 11 than the fluid enters the receiving space 11. Before washing, the fluid extraction assembly is operated to extract the receiving space 11 into a negative pressure state. A pressure gauge is arranged in the washing container and used for detecting the air pressure in the washing container. During the washing period, the fluid extraction assembly is continuously operated to extract the fluid in the accommodating space 11, when the air pressure in the washing container is higher than the first preset value, the fluid inlet assembly 30 is closed, and when the fluid extraction assembly extracts the fluid to enable the air pressure in the washing container to be lower than the first preset value, the fluid inlet assembly 30 is opened again to input the fluid into the accommodating space 11. In this way, the negative pressure can be always maintained in the housing space 11.
During washing, the fluid extraction assembly is continuously operated, so that the starting and stopping times of the fluid extraction assembly can be reduced, the service life is prolonged, and the power consumption is reduced.
Referring to fig. 5 and 7, in some embodiments, 02: the fluid extraction from the receiving space 11 by the fluid extraction assembly comprises:
022: during washing, the following steps are performed alternately: the fluid extraction assembly is operated for a first preset duration and stopped for a second preset duration to extract the fluid from the receiving space 11.
Referring to fig. 3, in certain embodiments, the program further includes instructions for performing the wash control method of 022.
Referring to fig. 3, in some embodiments, the control button is also used to trigger instructions for executing the 022 washing control method.
When the fluid extraction assembly operates, the interior of the washing container is in a negative pressure state, and the fluid in the impeller assembly 20 can be sucked in and the impeller assembly 20 is driven to rotate, so as to stir the cleaning fluid and the object to be cleaned. When the fluid extraction assembly stops operating, as the gas continuously enters the washing container, the air pressure in the washing container gradually rises, the capability of the negative pressure to suck the fluid of the impeller assembly 20 is gradually weakened, the stirring capability of the impeller and the impact capability of the fluid on the cleaning liquid are gradually reduced, and the object to be cleaned can be properly unfolded. After the fluid extraction assembly operates again, the air pressure in the washing container is gradually reduced, so that negative pressure is generated in the washing container again to drive the impeller to rotate and stir the object to be cleaned. The cleaning device has the advantages that each position of an object to be cleaned can be effectively cleaned in the repeated 'stirring' and 'stretching' process, and the cleaning effect is better. With the reciprocating start and stop of the fluid extraction assembly according to a certain frequency, the fluid of the impeller assembly 20 also impacts the cleaning fluid and the object to be cleaned at a certain frequency, and the object to be cleaned is intermittently impacted and spread, so that the cleaning effect is better compared with continuous impact.
In certain embodiments, the first predetermined period of time is greater than the second predetermined period of time, i.e., the period of time during which the fluid is withdrawn is greater than the period of time during which the withdrawal of fluid is stopped, to ensure that a negative pressure is maintained within the wash vessel.
In some embodiments, the first predetermined period is equal to or less than 30 seconds and the second predetermined period is equal to or less than 10 seconds. So that the fluid of the pulsator assembly 20 impacts the cleaning solution and the object to be cleaned at a certain frequency, thereby improving the cleaning effect.
Referring to fig. 4 and 8, in some embodiments, the pulsator assembly 20 includes a first flow channel 214 and a second flow channel 215 isolated from each other; when the valve 27 connects the external fluid to the first flow channel 214 and the fluid extraction assembly extracts the fluid from the accommodating space 11, the pulsator assembly 20 rotates forward; when the valve 27 connects the external fluid to the second flow channel 215 and the fluid extraction assembly extracts the fluid from the receiving space 11, the pulsator assembly 20 rotates in the reverse direction. Referring to fig. 4, the cleaning device is programmed to control the rotation of the wave wheel assembly 20 in forward or reverse direction by controlling the flow passage of the valve 27.
For example, in the embodiment illustrated in fig. 8, the vane 23 includes first and second opposing sides 2314 and 2315, the first side 2314 is provided with a first outlet 2114, the second side 2315 is provided with a second outlet 2115, the first flow passage 214 communicates the first outlet 2114 with the inlet 221, and the second flow passage 215 communicates the second outlet 2115 with the inlet 221. If the pulsator assembly 20 rotates counterclockwise, the rotation direction is forward rotation, and the rotation direction is reverse rotation. When the valve 27 is deflected to the right side, the fluid in the second flow passage 215 can be blocked from entering the accommodating space 11 of the washing container 10 from the second outlet 2115, and at the same time, the path of the fluid flowing out of the first flow passage 214 from the first outlet 2114 is opened, so that the fluid in the pulsator assembly 20 enters the accommodating space 11 from the first outlet 2114, and the fluid at the first outlet 2114 is "sucked" into the accommodating space 11 under the action of negative pressure, so as to drive the pulsator assembly 20 to rotate forward. When the valve 27 is deflected to the left, the fluid in the first flow passage 214 can be blocked from entering the accommodating space 11 of the washing container 10 from the first outlet 2114, and the path of the fluid flowing out of the second outlet 2115 from the second flow passage 215 can be opened, so that the fluid in the pulsator assembly 20 can enter the accommodating space 11 from the second outlet 2115. The fluid at the second outlet 2115 is "sucked" into the accommodating space 11 under the action of negative pressure, and the impeller assembly 20 is driven to rotate reversely.
In other embodiments, the clockwise rotation direction of the pulsator assembly 20 may be a forward rotation direction, and the counterclockwise rotation direction may be a reverse rotation direction, which is not limited herein.
Referring to fig. 5 and 9, in some embodiments, 03: the washing liquid in the containing space 11 is driven by the rotation of the pulsator assembly 20 to wash the clothes in the containing space 11, which includes:
031: the pulsator assembly 20 rotates forward and the pulsator assembly 20 rotates backward alternately, so as to drive the cleaning solution in the accommodating space 11 to clean the clothes in the accommodating space 11.
Referring to fig. 3, in some embodiments, the program further includes instructions for executing the washing control method 031.
Referring to fig. 3, in some embodiments, the control button is further used to trigger an instruction for executing the 031 washing control method.
The pulsator assembly 20 rotates forward and turns alternately, so that the object to be cleaned is fully spread after being agitated in one direction and is agitated in the other direction. Therefore, all positions of the object to be cleaned can be effectively cleaned, and the cleaning effect is better. And the problem that the winding part is difficult to clean due to the mutual winding of the objects to be cleaned can be avoided.
In certain embodiments, alternating forward and reverse rotation of the impeller assembly 20 is performed with the fluid extraction assembly stopped. For example, during washing, the fluid extraction assembly is operated to rotate the pulsator in a forward direction, the fluid extraction assembly is stopped and the rotational direction of the pulsator assembly 20 is changed, the fluid extraction assembly is operated again to rotate the pulsator in a reverse direction, the fluid extraction assembly is stopped and the rotational direction of the pulsator assembly 20 is changed, and so on. The forward rotation and the reverse rotation of the impeller assembly 20 are alternatively matched with the frequency of the fluid of the impeller assembly 20 impacting the cleaning fluid and the object to be cleaned and the stirring and stretching frequency of the object to be cleaned, so that the cleaning effect is improved.
Referring to fig. 3, in some embodiments, the cleaning apparatus 100 further includes a heating unit 70, and the heating unit 70 is used for heating the washing container 10. The heated washing container 10 can increase the temperature of the liquid in the washing container 10, so that stains can be dissolved in the liquid more easily and quickly, thereby improving the cleaning capacity and efficiency of the cleaning device 100.
The heating unit 70 may be a resistance wire, and the washing container 10 may be made of metal, so that the washing container 10 can be heated quickly. In one embodiment, heating unit 70 is located at the bottom of washing container 10 to facilitate electrical connection.
In some embodiments, the heating unit 70 is used to heat the fluid in the fluid inlet assembly 30 such that the fluid with a certain temperature enters the interior of the washing container 10 from the fluid inlet assembly 30 to make stains more easily and quickly dissolved in the liquid, thereby improving the cleaning ability and efficiency of the cleaning device 100.
Referring to fig. 10, in some embodiments, the washing control method further includes:
04: the heating unit 70 is turned on to heat the cleaning liquid in the storage space 11.
The heated washing container 10 can increase the temperature of the liquid in the washing container 10, so that stains can be dissolved in the liquid more easily and quickly, thereby improving the cleaning capacity and efficiency of the cleaning device 100.
In certain embodiments, 03: the washing liquid in the containing space 11 is driven by the rotation of the pulsator assembly 20 to wash the clothes in the containing space 11, which includes: 033: the heated cleaning liquid is driven by the rotation of the pulsator assembly 20 to clean the clothes in the accommodating space 11.
Referring to fig. 3, in some embodiments, the program further includes instructions for performing the washing control methods of 04 and 033.
Referring to fig. 3, in some embodiments, the control button is also used to trigger the instructions for executing the washing control methods 04 and 033.
Referring to fig. 3, the heating unit 70 may be turned on to heat the cleaning solution in the storage space 11 during the washing process, or may be pre-heated before the washing process, which is not limited herein.
Referring to fig. 11, in some embodiments, the washing control method further includes:
05: the heating unit 70 is turned on to heat the fluid entering the assembly 30.
In this manner, fluid having a temperature can be passed from the fluid intake assembly 30 into the interior of the washing container 10 to make stains more easily and quickly dissolved in the liquid to improve the cleaning ability and cleaning efficiency of the cleaning apparatus 100.
Referring to fig. 3, in some embodiments, the program further includes instructions for performing the wash control method of 05.
Referring to fig. 3, in some embodiments, the control button is further used to trigger an instruction for executing the washing control method of 05.
Referring to fig. 3, in some embodiments, the fluid pumping assembly pumps the fluid to the accommodating space 11 at a first power without turning on the heating unit 70, and the fluid pumping assembly pumps the fluid to the accommodating space 11 at a second power with the heating unit 70 turned on, wherein the second power is less than the first power.
In the case of turning on the heating unit 70, the stains are more easily dissolved, and the requirement for stirring the object to be cleaned and the cleaning liquid, i.e., the requirement for the rotational speed of the pulsator assembly 20, can be reduced. The rotating speed of the pulsator assembly 20 is related to the operating power of the fluid pumping assembly, and the higher the operating power is, the greater the suction force of the negative pressure in the washing container to the fluid in the pulsator assembly 20 is, and the faster the rotating speed of the pulsator assembly 20 is, the stronger the stirring capability is. Under the condition that the heating unit 70 is not turned on, the fluid extraction assembly extracts the fluid from the accommodating space 11 at a larger first power, so as to improve the stirring capability of the pulsator assembly 20 and accelerate the stain dissolution. Under the condition that the heating unit 70 is turned on, the fluid extraction assembly extracts the fluid from the accommodating space 11 with a smaller second power, so as to reduce the rotation speed of the pulsator assembly 20, reduce the friction between the pulsator assembly 20 and the object to be cleaned, and prevent the object to be cleaned from being damaged.
In some embodiments, the pulsator assembly 20 rotates at a first rotation speed, and the pulsator assembly 20 rotates at a second rotation speed, which is less than the first rotation speed, while the heating unit 70 is turned on. The rotating speed of the pulsator assembly 20 may be controlled by adjusting the discharge amount of the pulsator assembly 20, in addition to being affected by the magnitude of the negative pressure in the washing tub. In one embodiment, the amount of air output by the pulsator assembly 20 may be controlled by a valve of the pulsator assembly 20. Without turning on the heating unit 70, the pulsator assembly 20 rotates at a first rotation speed that is relatively large to improve the agitating capability of the pulsator assembly 20 and accelerate the dissolution of the contaminants. In the case where the heating unit 70 is turned on, the pulsator assembly 20 rotates at a second rotational speed, which is smaller, to reduce friction between the pulsator assembly 20 and the object to be cleaned, thereby preventing the object to be cleaned from being damaged.
In some embodiments, the pulsator assembly 20 rotates to drive the cleaning solution in the accommodating space 11 to clean the laundry in the accommodating space 11 for a first time period without turning on the heating unit 70; when the heating unit 70 is turned on, the pulsator assembly 20 rotates to drive the washing liquid in the accommodating space 11 to wash the laundry in the accommodating space 11 for a second time period, and the first time period is shorter than the second time period. That is, when the heating unit 70 is turned on, the dissolution of the soil can be accelerated, and thus the washing time can be shortened and the cleaning efficiency can be improved.
