[0034] When washing clothes, the washing machine drives the clothes and washing water to roll through the washing tub to achieve the purpose of washing clothes. During the washing process, the clothes will continue to be affected by friction, mechanical force, water flow impact, hot and cold water temperature, detergents and other care agents, etc., to clean the stains adhering to the clothes, and dissolve and remove the detergent residues and stain residues through multiple rinsing, thereby achieving the purpose of cleaning the clothes. However, during the washing process, impurities such as hair carried on the clothes and the lint generated during the washing process will move with the washing water, which is easy to cause repeated contamination to the clothes, thereby affecting the washing quality. Therefore, a washing machine is proposed to solve the above problems.

[0035] The scheme is further illustrated by the following examples:

[0036] Figure 1 It is a schematic diagram of a washing machine according to an embodiment of the utility model. Figure 2 yes Figure 1 Another schematic diagram of a washing machine.

[0037] See also Figure 1 and Figure 2 The washing machine of the present application may include a housing 10 , a circulation assembly 20 , a filter assembly 30 and a nozzle assembly 40 .

[0038] A washing tub 11 may be disposed in the housing 10 for accommodating clothes, washing water, and the like.

[0039] The circulation assembly 20 may include a circulation pipe 21 and a circulation pump 22. The circulation pipe 21 and the circulation pump 22 may be both mounted on the housing 10.

[0040] One end of the circulation pipe 21 may be connected to the bottom of the washing tub, and the other end of the circulation pipe 21 may be connected to the top of the washing tub.

[0041] The circulation pump 22 may be used to drive the washing water in the washing tub 11 to flow between the circulation pipe 21 and the washing tub 11 .

[0042] The filter component 30 can be set at the water outlet of the circulation pipe 21 to filter the washing water flowing through the circulation pipe 21, thereby intercepting impurities such as hair and lint carried in the washing water, and preventing impurities such as hair and lint from causing secondary contamination to the clothes in the washing tub 11.

[0043] See also Figure 1 and Figure 2 , the shell 10 can be set as an outer barrel.

[0044] The washing tub 11 may be installed in the outer tub. The washing tub 11 can rotate relative to the outer tub, so that the housing 10 can support the washing tub 11.

[0045] The circulation assembly 20 may be used to flow the wash water in the wash tub 11 .

[0046] A filter net may be provided in the filter assembly 30 so that the filter assembly 30 can filter the washing water flowing along the circulation pipe 21, thereby intercepting impurities such as hair and thread scraps in the washing water.

[0047] The nozzle assembly 40 may be connected to the water outlet of the circulation pipe 21 for spraying wash water.

[0048] See also Figure 1 and Figure 2 The washing tub 11 may be provided with a loading port 12 for loading clothes and detergent.

[0049] The housing 10 may be provided with a door.

[0050] The door is rotatably connected to the housing 10 so as to be able to open and close the loading port 12, thereby facilitating the loading of clothes, detergents, etc.

[0051] In some other embodiments, a door seal 14 may be provided on the housing 10 .

[0052] The door seal 14 may be connected to the housing 10 and located on the loading port 12 .

[0053] The filter assembly 30 can be detachably mounted on the housing 10 .

[0054] The filter assembly can be located on the side of the door facing the washing tub 11, so that the filter assembly 30 can be removed from the shell 10, which is convenient for cleaning the filter assembly 30, thereby ensuring the filtering capacity of the filter assembly 30 and improving the washing effect.

[0055] The filter assembly 30 may be detachably connected to the door seal 14 to facilitate removal and installation of the filter assembly 30 .

[0056] The water outlet of the filter assembly 30 may be connected to the washing tub 11 , so that the washing water filtered by the filter assembly 30 may flow into the washing tub 11 .

[0057] See also Figure 3 ,The washing machine can be provided with a front panel 13.

[0058] The delivery port 12 may be provided on the front plate 13 , and a box door may be provided on the front plate 13 to open or close the delivery port 12 .

[0059] The loading port 12 can also be used as an observation window, and the loading port can be a structure made of transparent or translucent materials to facilitate people to observe the washing status of the clothes.

[0060] See also Figure 1 and Figure 2 The nozzle assembly 40 may be connected to the water outlet of the circulation pipe 21. The water outlet of the nozzle assembly 40 may be provided with a spray port 41 and a filter port 42.

[0061] The spray port 41 can be directly directed toward the washing tub to spray washing water toward the washing tub 11, so that the detergent in the washing water can be evenly sprayed onto the washed clothes, thereby improving the washing effect. The filter port 42 can be directed toward the filter assembly 30 to spray washing water toward the filter assembly 30 and enable the filter assembly 30 to filter the washing water.

[0062] The spray port 41 can be selectively opened or closed.

[0063] When the spray port 41 is closed, the washing water in the circulation pipe 21 can be sprayed from the filter port 42 onto the filter assembly 30, so that the filter assembly 30 can filter the washing water, thereby intercepting impurities such as hair and thread scraps carried in the washing water, ensuring the cleanliness of the washing water, and thus improving the washing effect. When the spray port 41 is opened, the washing water in the circulation pipe 21 can be directly sprayed into the washing tub 11, thereby increasing the contact area between the detergent and the clothes in the washing tub 11, so that the detergent can evenly contact the clothes, thereby improving the washing effect.

[0064] The filter port 42 can also be selectively opened or closed.

[0065] When impurities in the washing water need to be filtered, the filter port 42 can be opened so that the washing water is sprayed along the circulation pipe 21 onto the filter assembly 30, thereby filtering the washing water. When the washing water needs to be sprayed onto the clothes in the washing tub 11, the filter port 42 can be selectively closed so that the washing water floods the circulation pipe 21 and sprays into the washing tub 11 from the spray port 41, thereby increasing the contact area between the washing water and the clothes, thereby improving the washing effect.

[0066] The spray port 41 may also be provided with a solenoid valve.

[0067] The solenoid valve on the spray port 41 is used to control the opening or closing of the spray port 41 .

[0068] Figure 4 yes Figure 1 A cross-sectional view of a nozzle assembly of a washing machine when it is retracted, Figure 5 yes Figure 1 A cross-sectional view of a washing machine nozzle assembly when extended.

[0069] See also Figure 4 and Figure 5 The nozzle assembly 40 may include a housing 43 and a spray head 44 .

[0070] The housing 43 can extend in a straight line, and the housing 43 has a receiving chamber 431 with both ends opened along its own axial direction. The receiving chamber 431 can extend in a straight line, and one end of the receiving chamber 431 is connected to the circulation pipe 21 to guide the washing water in the circulation pipe 21 into the receiving chamber 431.

[0071] The water inlet end of the spray head 44 may be installed in the accommodating cavity 431 , and the water outlet end of the spray head 44 may be located outside the housing 43 , so that the washing water in the accommodating cavity 431 can be sprayed along the spray head 44 .

[0072] A filter port 42 may be provided at an axial end of the spray head 44 , and the filter port 42 faces and is directly opposite to the filter assembly 30 , so as to be able to spray washing water toward the filter assembly 30 .

[0073] A spray port 41 may be provided on the peripheral side of the spray head 44 .

[0074] The filter port 42 and the spray port 41 may both be opened at the water outlet end of the spray head 44 , so that the washing water can be sprayed out from the water outlet end of the spray head 44 .

[0075] See also Figure 5 The spray port 41 and the axis of the spray head 44 may form an inclined angle, so that after the spray head 44 extends out of the accommodating cavity 431, the washing water sprayed from the spray port 41 can be better sprayed onto the clothes in the washing tub 11, thereby improving the spraying effect.

[0076] The spray port 41 and the filter port 42 may be disposed at the axial end of the spray head 44 so that the spray port 41 and the filter port 42 can spray washing water respectively.

[0077] Of course, the spray port 41 and the filter port 42 may also be disposed on the radial circumferential side of the spray head 44 so that the spray port 41 and the filter port 42 can spray washing water respectively.

[0078] In addition, the shapes of the housing 43 and the nozzle 44 may both be column-like, and the shape of the accommodating cavity 431 is similar to that of the nozzle 44 , so that the nozzle 44 can be installed in the accommodating cavity 431 .

[0079] See also Figure 4 and Figure 5 The nozzle 44 can be slidably connected to the shell 43 along the axial direction of the accommodating cavity 431, so that the water outlet end of the nozzle 44 can be retracted into the accommodating cavity 431, or the water outlet end of the nozzle 44 can be extended to the outside of the shell 43, so that the spray port 41 on the nozzle 44 can be selectively opened or closed.

[0080] When the water outlet end of the nozzle 44 is retracted into the accommodating chamber 431, the nozzle 44 is located at the retracted position, and the spray port 41 is closed. Figure 4 shown.

[0081] When the water outlet end of the spray head 44 extends to the outside of the housing 43, the spray head 44 is in the extended position, and the spray port 41 is opened. Figure 5 shown.

[0082] Since the spray port 41 is disposed on the circumference of the spray head 44, when the spray head 44 is retracted into the accommodating cavity 431, that is, when the spray head 44 is located in the retracted position, the inner wall of the accommodating cavity 431 will block the spray port 41 located on the circumference of the spray head 44, thereby closing the spray port 41 and preventing the washing water from being sprayed from the spray port 41. When the spray head 44 is extended to the outside of the accommodating cavity 431, that is, when the spray head 44 is located in the extended position, the spray port 41 is not blocked, so that the spray port 41 can spray the washing water.

[0083] Therefore, the spray port 41 can be closed or opened by the spray head 44 being retracted into the accommodating cavity 431 or being extended out of the accommodating cavity 431 .

[0084] See also Figure 4 and Figure 5 The aperture of the filter port 42 may be smaller than the tube diameter 442 of the nozzle 44 , so that the nozzle 44 can slide relative to the housing 43 when the water pressure in the nozzle 44 exceeds a preset pressure value.

[0085] When the aperture of the filter port 42 is smaller than the tube diameter of the nozzle 44 and the water pressure in the nozzle 44 exceeds a preset pressure value, the nozzle 44 is subjected to increased water pressure due to the obstruction of the end structure of the nozzle 44, so that the water in the nozzle 44 can push the nozzle 44 to move relative to the outer shell 43, so that the end of the nozzle 44 extends out of the accommodating cavity 431 and moves to the extended position, thereby enabling the spray port 41 to spray washing water toward the washing tub 11.

[0086] The circulation component 20 can increase the output power of the circulation pump 22 to increase the water pressure in the circulation pipe 21, so that the washing water in the circulation pipe 21 can drive the nozzle 44 to move relative to the shell 43 to extend the water outlet end of the nozzle 44 out of the accommodating cavity 431.

[0087] The circulation component 20 can also be provided with a driving motor or the like between the housing 43 and the nozzle 44 to drive the nozzle 44 to move relative to the housing 43 .

[0088] See also Figure 4 and Figure 5 Since the spray head 44 can move relative to the housing 43 , in order to enable the spray head 44 to automatically return to the initial position, the nozzle assembly 40 may further include a damper 45 .

[0089] The damper 45 can be connected between the outer peripheral side of the nozzle 44 and the inner wall of the accommodating chamber 431 to limit the nozzle 44 in the retracted position, that is, the damper 45 can limit the nozzle 44 in the accommodating chamber 431 to prevent the nozzle 44 from automatically extending out of the accommodating chamber 431.

[0090] The damper 45 may be configured as a spring to limit the spray head 44 in the accommodating cavity 431 by elastic force.

[0091] The damper 45 may also be configured as an elastic spring plate or an elastic plastic sleeve, etc., so that the damper 45 can limit the nozzle 44 in the accommodating chamber 431 .

[0092] See also Figure 4 and Figure 5 The nozzle assembly 40 may further include a cover 46 .

[0093] The cover 46 may be provided with a through hole 461 for passing the nozzle 44 therethrough.

[0094] The sealing cover 46 can be connected to one end of the shell 43 away from the circulation pipe 21, so that when the nozzle 44 is in the retracted position, the inner wall of the through hole 461 can fit on the spray port 41, thereby closing the spray port 41.

[0095] Figure 6 yes Figure 1 Schematic diagram of the outer casing of a washing machine, Figure 7 yes Figure 1 A cross-sectional view of the outer casing of a washing machine, Figure 8 yes Figure 1 Another schematic diagram of the housing of a washing machine.

[0096] See also Figure 6 A stop rib 433 may be provided on the outer peripheral side of the housing 43 .

[0097] The stopping rib 433 may be located at one end of the housing 43 facing the circulation pipe 21 for connecting the circulation pipe 21 .

[0098] See also Figure 7 and Figure 8 A guide groove 432 may be formed on the inner wall of the accommodating cavity 431 , and the guide groove 432 extends along the axial direction of the shell 43 .

[0099] Fig. 9 yes Figure 1 Schematic diagram of the nozzle of the washing machine. Fig.10 yes Figure 1 Another schematic diagram of the nozzle of the washing machine, Fig.11 yes Figure 1 A cross-sectional view of a nozzle of a washing machine.

[0100] See also Figure 9-11A guide rib 441 may be protrudingly provided on the outer peripheral side of the nozzle 44 .

[0101] The guide rib 441 is matched with the guide groove 432 , and the guide rib 441 is clamped in the guide groove 432 to limit the nozzle 44 from rotating along its own axis.

[0102] The guide rib 441 can slide relative to the guide groove 432, so that when the nozzle 44 slides relative to the shell 43, a limit is formed between the guide rib 441 and the guide groove 432 to prevent the nozzle 44 from rotating along the axis of the nozzle 44 relative to the shell 43, thereby avoiding changes in the spraying direction of the spray port 41.

[0103] See also Figure 5 and Figure 7 The guide groove 432 may be provided along the axial direction of the accommodating cavity 431 to allow the nozzle 44 to move to the extended position relative to the housing 43 .

[0104] Since the cover 46 is connected to the end of the shell 43 away from the circulation pipe 21 , when the nozzle 44 is in the extended position, the cover 46 can limit the guide rib 441 on the nozzle 44 to prevent the guide rib 441 from escaping from the guide groove 432 .

[0105] In addition, two guide grooves 432 and two guide ribs 441 may be provided to limit the nozzle 44. Of course, one or more guide grooves 432 and two or more guide ribs 441 may be provided to limit the nozzle 44.

[0106] See also Figure 1 and Figure 2 The washing machine may further include a drain pipe 51 and a drain pump 52 .

[0107] The drain pipe 51 may be connected to the circulation pipe 21 via a drain pump 52 to discharge wash water.

[0108] Since one end of the circulation pipe 21 is connected to the bottom of the washing tub 11, one end of the drain pipe 51 is connected to the circulation pipe 21 through the drain pump 52. The washing water in the washing tub 11 can be discharged with the help of the circulation pipe 21, thereby simplifying the structure of the washing machine and reducing manufacturing costs.

[0109] When the washing machine circulates washing water, the circulation pump 22 operates to drive the washing water to flow back into the washing tub 11 along the circulation pipe 21 .

[0110] When the washing machine needs to drain the washing water, the drain pump 52 starts working, driving the washing water along the circulation pipe 21 into the drain pipe 51, and then discharged out of the shell 10 along the drain pipe 51, thereby draining the washing water.

[0111] The washing process of the washing machine of the present application comprises the following steps:

[0112] Step 1: When washing clothes, the circulation pump 22 works at the first power, thereby driving the washing water to flow along the circulation pipe 21 and flow out through the filter port 42, so that the filter assembly 30 can filter the washing water.

[0113] Step 2: After the circulation pump 22 works for a predetermined time, the circulation pump 22 works at a second power to drive the washing water to flow along the circulation pipe 21 and flow out through the spray port 41 so as to spray the washing water toward the inside of the washing tub 11 .

[0114] Step 3: When the washing tub 11 finishes washing, the drain pump 52 works to drain the washing water in the washing tub 11 .

[0115] In summary, in the process of washing clothes in the washing machine, after the washing water and detergent are added, the washing tub 11 rotates to wash the clothes. During the washing process, the circulating pump 22 works at a first power to drive the washing water to flow along the circulating pipe 21. At this time, the washing water is sprayed from the filter port 42 along the circulating pipe 21 to the filter assembly 30, so that the filter assembly 30 can filter the hair, wire scraps and other debris carried by the washing water. After the circulating pump 22 works at the first power for a period of time, the filter assembly 30 can complete the filtration of impurities in the washing water. At this time, the circulating pump 22 works at a second power. Since the second power is greater than the first power, the water pressure in the circulating pipe 21 becomes larger, so that the water in the circulating pipe 21 can push the nozzle 44 to move axially relative to the housing 43, so that the nozzle 44 moves toward the extended position, thereby opening the spray port 41 and allowing the washing water to be sprayed toward the washing tub 11. At this time, the washing water is sprayed directly toward the clothes in the washing tub 11, so that the washing water and detergent can be better sprayed onto the clothes, thereby improving the washing effect.
