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 and 2, 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 40. 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 40 is connected to the washing container 10, and the fluid extraction assembly 40 is used for extracting the fluid in the accommodating space 11, so that the 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 40, 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.

The cleaning device 100 is further described below with reference to the accompanying drawings:

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 a first end 12 and a second end 13 opposite to each other, a fluid inlet assembly 30 is disposed at the first end 12, and a fluid extraction assembly 40 is disposed at the second end 13. As shown in fig. 1 and 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, first end 12 is a bottom wall 16, fluid intake assembly 30 is disposed in bottom wall 16, second end 13 is a top wall 15, and fluid extraction assembly 40 is disposed in 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 40 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 40 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, in some embodiments, the fluid intake assembly 30 is disposed at the first end 12 opposite the fluid extraction assembly 40 disposed at the second end 13. Wherein the fluid intake assembly 30 is aligned with the fluid extraction assembly 40, i.e. a line connecting the center 31 of the fluid intake assembly 30 and the center 41 of the fluid extraction assembly 40 is parallel to the central axis 18 of the washing container 10. In this manner, energy losses during fluid ingress and egress to and from the wash vessel 10 can be reduced. In one embodiment, the first end 12 is located at the bottom wall 16, the second end 13 is located at the top wall 15, the fluid intake assembly 30 is disposed at a middle portion of the first end 12, the fluid extraction assembly 40 is also disposed at a middle portion of the second end 13, and a line connecting a center of the fluid intake assembly 30 and a center of the fluid extraction assembly 40 coincides with a central axis of the washing container 10 to further reduce energy loss during fluid entering and exiting the washing container 10. In other embodiments, the line connecting the center of the fluid inlet assembly 30 and the center of the fluid extraction assembly 40 may be parallel to and offset from the central axis of the washing container 10, which is not limited herein. The center of the fluid intake assembly 30 may be offset from the center of the fluid extraction assembly 40, and is not limited herein.

Referring to fig. 1 and 4, in some embodiments, the impeller 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. 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 22 washing machine does not flow in a turbulent manner, and a stable saturated layer is formed on the surface of the object to be cleaned when the flowing liquid comes into contact with the object to be cleaned, resulting in difficulty in separating the dirt 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 outlet 211 of the flow channel 21 is disposed at a side of the blade 23, so that the exit direction of the fluid entering the accommodating space 11 from the outlet 211 is a tangential direction of the rotation of the pulsator assembly 20. Referring to fig. 4, 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 pulsator 22 to perform circular motion, and the exit direction of the fluid is the tangential direction of the pulsator 22 performing circular motion rotation.

In some embodiments, the number of blades 23 is odd, such as 3, 5, 7, etc., not listed herein. The odd number of blades 23 can reduce resonance in the rotation process and improve the dynamic balance of the rotation of the blades 23.

In some embodiments, the number of blades 23 is even and the shape of the blades 23 is not uniform enough to reduce resonance during rotation and improve the dynamic balance of the rotation of the blades 23. For example, the number of blades 23 is 4, wherein the size of 1 blade 23 is different from the size of the other 3 blades 23.

Referring to fig. 5, in some embodiments, the blades 23 are disposed on the circumferential surface 221 of the impeller 22. For example, the root of the blade 23 is connected to the circumferential surface 221 of the pulsator 22. Referring to fig. 1, the impeller 22 and the blades 23 are located close to the bottom wall 16 of the washing container 10, so that the impeller assembly 20 is not easily contacted with the object to be cleaned during the rotation process, and the object to be cleaned is prevented from being damaged by the friction between the impeller assembly 20 and the object to be cleaned.

Referring to fig. 4, in some embodiments, the blades 23 are disposed on the upper surface 222 of the pulsator 22. Referring to fig. 1, in an embodiment, a distance between a highest point of the top surface of the blade 23 and the top surface is [2.0cm, 4.0cm ], so that the pulsator assembly 20 is close to the bottom wall 16 of the washing container 10, and the pulsator assembly 20 is not easily contacted with an object to be cleaned during a rotation process, thereby preventing the object to be cleaned from being damaged by friction between the pulsator assembly 20 and the object to be cleaned.

Referring to fig. 1, in some embodiments, the fluid intake assembly 30 further comprises a valve (not shown). A valve is provided in the inlet conduit 32 and is used to regulate the flow of fluid through the inlet conduit 32. The rotating speed of the pulsator assembly 20 can be controlled by adjusting the flow of the fluid, so as to control the rotation of the pulsator assembly 20 to drive the liquid in the washing container 10 to generate turbulence.

In some embodiments, the valve is closed before the fluid extraction assembly 40 draws air to create a predetermined negative pressure, to prevent external fluid from flowing into the washing container 10 if the negative pressure in the washing container 10 does not reach the predetermined value, thereby assisting in the creation of a predetermined amount of negative pressure in the washing container 10.

Referring to fig. 3, in some embodiments, the fluid extraction assembly 40 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. 1, in some embodiments, the extraction pipe 44 is mounted to the cover plate 90 and located in the accommodating space 11. The extraction unit 42 and the power unit 43 are mounted on the other side of the cover plate 90, opposite to the side of the cover plate 90 on which the extraction duct 44 is mounted.

In some embodiments, the pumping unit 42 is a water pump for pumping the liquid in the receiving space 11, and the pumping pipe 44 extends into the receiving space 11 and is located at a certain height from the top wall 15 of the washing container 10, so that the liquid in the receiving space 11 can flow through the pumping pipe 44, and the pumping unit 42 is convenient to pump the liquid.

Referring to fig. 6, in some embodiments, extraction conduit 44 includes a plurality of channels 441, each channel 441 radiating helically from the center of extraction unit 42. Therefore, the air bubbles entering the extraction pipeline 44 are easy to be broken in the process of extracting the fluid, the extraction efficiency is improved, and washing materials such as washing powder and laundry detergent in the air bubbles can enter the washing container 10 again, so that the waste of the washing materials is reduced, and the utilization rate of the washing materials is improved.

Referring to fig. 1, 3 and 6, in some embodiments, the extraction duct 44 is provided with an extraction port 442 communicating with the receiving space 11, the fluid inlet assembly 30 includes the inlet duct 32, and the opening size of the extraction port 442 is larger than the opening size of the inlet port 321 of the inlet duct 32. As shown in fig. 1, the suction port 442 is an outlet size of the fluid from the receiving space 11, and the size of the suction port 442 determines a maximum flow rate of the fluid drawn from the receiving space 11. The flow rate of the fluid flowing out of the outlet of the flow passage 21 does not exceed the flow rate of the fluid entering the pipe 32 from the inlet 321, and therefore the size of the inlet 321 determines the maximum flow rate into the housing space 11. In this way, the outflow volume of the fluid is ensured to be larger than the inflow volume of the fluid, so that the receiving space 11 is always kept at a negative pressure, and the fluid entering the assembly 30 can be ensured to continuously enter the receiving space 11 under the action of the negative pressure.

Referring to fig. 1, in some embodiments, the external fluid includes gas, the gas enters the impeller assembly 20 through the fluid inlet assembly 30 and drives the impeller assembly 20 to rotate, and the fluid extraction assembly 40 is configured to extract the gas in the accommodating space 11, so as to form a negative pressure in the accommodating space 11; the suction port 442 and the inlet port 321 form a funnel-shaped air duct. That is, the diameter of the air duct is the smallest at the end close to the inlet port 321, and the diameter of the air duct gradually increases from the end of the inlet port 321 to the end of the suction port 442. Thus, energy loss of gas in the process of flowing into the inlet 321 from the suction port 442 can be reduced, a turbulent flow phenomenon is avoided, and energy of the gas flow is efficiently utilized.

Referring to FIG. 7, in some embodiments, the cleaning device 100 further includes a reservoir 50. The reservoir 50 is for storing a cleaning liquid and for injecting the cleaning liquid into the accommodating space 11. Wherein, the cleaning solution can be a solution mixed with washing materials such as washing powder, laundry detergent and the like. Since the receiving space 11 needs to be maintained in a negative pressure state during cleaning, a sealing performance of the washing container 10 is required. The water taps are of various sizes, and a water filling channel (not shown) of the washing container 10 is difficult to realize compatibility with various water taps and sealing performance. The water outlet channel 51 of the liquid storage container 50 is matched with the water filling channel of the washing container 10 in size, and the water outlet channel 51 and the water filling channel are sealed to ensure that the accommodating space 11 can maintain a negative pressure state.

In one embodiment, the reservoir 50 is removably coupled to the wash container 10 to allow the reservoir 50 to be stored or transported separately from the wash container 10 without cleaning, facilitating storage and movement of the reservoir 50 and the wash container 10. In case that it is necessary to fill the cleaning solution into the accommodating space 11, if the washing container 10 is not convenient to move, the liquid storage container 50 may be detached and the cleaning solution may be filled into the liquid storage container 50, and then the liquid storage container 50 may be connected to the washing container 10 and the cleaning solution may be filled into the accommodating space 11 through the liquid storage container 50. In this way, when the washing container 10 is far from a water source such as a faucet, the cleaning device 100 can inject the cleaning liquid into the storage space 11, and can perform washing at any position.

In one embodiment, the reservoir 50 is fixedly connected to the washing container 10, the liquid inlet of the reservoir 50 is closed after the injection of the cleaning liquid into the reservoir 50 is completed, and the water filling channel and the water outlet channel 51 between the reservoir 50 and the washing container 10 are opened, so that the cleaning liquid can enter the washing container 10 from the reservoir 50, and the sealing performance between the reservoir 50 and the washing container 10 is ensured.

Referring to fig. 8, in some embodiments, the external fluid includes a liquid, the liquid enters the impeller assembly 20 through the fluid inlet assembly 30 and drives the impeller assembly 20 to rotate, and the fluid extraction assembly 40 is configured to extract the liquid in the accommodating space 11, so as to form a negative pressure in the accommodating space 11. Liquid drawn from the receiving space 11 by the fluid drawing assembly 40 is stored in the liquid reservoir 50, and the liquid in the liquid reservoir 50 can pass through the fluid inlet assembly 30 and enter the receiving space 11. Thus, the cleaning liquid can be recycled, and the washing material in the cleaning liquid can return to the accommodating space 11 again to clean the object to be cleaned, so that the waste can be reduced.

Referring to FIG. 9, in some embodiments, the washing container 10 is an inner cylinder of the cleaning apparatus 100, the liquid storage container is an outer cylinder of the cleaning apparatus 100, and the inner cylinder is accommodated in the outer cylinder. The inner cylinder is sleeved with the outer cylinder, so that the structure is simple, the sealing performance is good, and the space utilization rate is high. The fluid extraction assembly 40 includes a first channel 45 and a second channel 46. The first passage 45 communicates with the outside atmosphere, and the second passage 46 communicates with the outer cylinder. Before cleaning, the fluid extraction assembly 40 opens the first passage 45 and closes the second passage 46 to extract gas from the inner cartridge to place the inner cartridge under negative pressure. When cleaning is carried out, liquid in the outer cylinder enters the inner cylinder under the action of negative pressure, and the fluid extraction assembly 40 opens the second channel 46 and closes the first channel 45 so as to extract the liquid in the inner cylinder back to the outer cylinder, so that the inner cylinder always maintains negative pressure difference relative to the outer cylinder, and the liquid in the outer cylinder can continuously enter the inner cylinder.

Referring to fig. 3, in some embodiments, the cleaning apparatus 100 further includes a drain unit 60. The drainage unit 60 communicates the housing space 11 with the outside, and is used for draining the liquid in the housing space 11.

Referring to fig. 9, 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 inside the fluid inlet assembly 30, so that the fluid with a certain temperature enters the interior of the washing container 10 from the fluid inlet assembly 30, so that the stains are dissolved in the liquid more easily and rapidly, thereby improving the cleaning capacity and efficiency of the cleaning device 100.

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 40. 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 washing vessel 10 adjacent to the fluid extraction assembly 40 has a larger internal diameter and the side adjacent to the fluid entry assembly 30 has a smaller internal diameter, i.e. the outlet aperture of the fluid leaving the washing vessel 10 is larger than the inlet aperture of the fluid entering the washing 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.
