[0033] Combination Figure 1-6 As shown, this embodiment of the present disclosure provides a washing machine including: a housing 200, a telescopic part 300, and a washing tub 400. The housing 200 defines a movable cavity 201 inside; the telescopic part 300 is disposed within the movable cavity 201 and can extend out of the housing 200 along one side of the movable cavity 201; the washing tub 400 includes an upward-facing opening and is disposed on the telescopic part 300, configured such that the opening is exposed when the telescopic part 300 extends out of the housing 200, and the opening is hidden when the telescopic part 300 retracts into the housing 200.

[0034] The washing machine provided in this embodiment has a telescopic part 300 inside and a washing tub 400 is disposed on the telescopic part 300. The washing tub 400 can extend or retract into the washing machine with the telescopic part 300. When the washing tub 400 extends out of the washing machine, the opening of the washing tub 400 is exposed, which makes it easy to put clothes into the washing tub 400 through the opening. After the clothes are put in, the washing tub 400 retracts into the interior of the washing machine. The structure is more stable and more convenient to use.

[0035] Optionally, the washing tub 400 is a pulsator washing tub 400. In this case, the pulsator washing tub 400 generally opens upwards, making it easier to put clothes in and more convenient to use.

[0036] Alternatively, the drive structure of the washing tub 400 and the structure of the impeller can both adopt structures commonly used in the field. This results in a simple and readily available structure, reducing production costs.

[0037] Optionally, a door panel 303 is provided on the front side of the telescopic part 300, and the width of the door panel 303 is the same as the width of the front side of the housing 200. In this way, the door panel 303 closes the opening of the movable cavity 201, maintains the sealing of the interior of the movable cavity 201, effectively reduces noise, and the door panel 303 is more aesthetically pleasing and provides a certain degree of protection for the telescopic part 300.

[0038] Optionally, a handle 304 is provided on the door panel 303. This allows the user to manually control the extension and retraction of the telescopic part 300, making it more convenient to use.

[0039] Optionally, a roller 301 is provided at the bottom of the side of the telescopic part 300 that extends out of the housing 200. This allows one end of the telescopic part 300 to extend out of the housing 200 more stably, maintaining the stability of the telescopic part 300.

[0040] Optionally, the telescopic part 300 and the movable cavity 201 are connected by a sliding structure 302. This maintains the stability of the connection between the telescopic part 300 and the movable cavity 201.

[0041] Optionally, the sliding structure 302 includes a groove and a slider, one of which is disposed on the telescopic part 300 and the other is disposed in the movable cavity 201. In this way, the slider slides stably within the groove by being embedded in it, thereby ensuring that the telescopic part 300 slides smoothly within the movable cavity 201.

[0042] Optionally, a roller groove 206 is provided on the front side of the bottom of the housing 200. In this way, after the telescopic part 300 is retracted into the housing 200, the roller 301 can be hidden in the roller groove 206, preventing the housing 200 from obstructing the roller 301.

[0043] Optionally, the bottom sides of the movable cavity 201 are provided with horizontally extending load-bearing protrusions 202. This can better support the weight of the telescopic part 300 and maintain the stability of the telescopic part 300.

[0044] Optionally, the load-bearing protrusion 202 and the housing 200 are integrally formed. This ensures the stability of the load-bearing protrusion 202 and improves its supporting force on the telescopic part 300.

[0045] Optionally, the load-bearing protrusion 202 is provided with a support leg at its lower part. In this way, the support leg supports the load-bearing protrusion 202, thereby improving the stability of the load-bearing protrusion 202.

[0046] Optionally, the load-bearing protrusion 202 is connected to the telescopic part 300 via a slide rail 203. This maintains the stability of the sliding of the telescopic part 300 and improves the smoothness of the telescopic part 300 during its telescopic movement.

[0047] Optionally, the slide rail 203 includes a groove 204 and a movable part 205. The movable part 205 is limited to sliding within the groove 204. In this way, the slide rail 203 can not only serve as a sliding connection, but also as a limiting function to maintain the stability of the connection between the load-bearing protrusion 202 and the telescopic part 300.

[0048] Optionally, the washing machine also includes a prompting device 500, disposed on the housing 200 or the telescopic part 300, configured to indicate the extension range of the telescopic part 300. This indicates the extension position of the telescopic part 300, preventing debris from appearing at the extension position and thus affecting the normal extension of the telescopic part 300, and maintaining the stability of the extension of the telescopic part 300.

[0049] Optionally, the prompting device 500 includes an infrared sensor. The infrared sensor is disposed on the telescopic portion 300 and configured to sense whether an obstacle exists in the extension area of ​​the telescopic portion 300. In this way, by detecting the presence of an obstacle, the infrared sensor provides a prompt to the user, preventing the obstacle from affecting the normal extension of the telescopic portion 300. The infrared sensor can be an infrared proximity switch or other electronic components commonly used in the art.

[0050] Optionally, the notification device 500 also includes a speaker. The speaker is configured to alert the user of the presence of an obstacle after the infrared sensor detects it. This allows for more convenient and faster notification of obstacles, facilitating timely removal of obstacles, preventing the telescopic part 300 from hitting obstacles, and improving safety.

[0051] Optionally, the prompting device 500 includes a projector configured to project an indication of the extension range of the telescopic part 300 in the extension direction of the telescopic part 300. By projecting the extension range of the telescopic part 300, the user can easily determine the area where the telescopic part 300 will extend, thereby clearing that area and preventing interference with the normal extension of the telescopic part 300.

[0052] Optionally, a projector is positioned on the telescopic section 300 corresponding to the roller 301, and is configured to mark the path of the roller 301 along the direction in which the telescopic section 300 extends. This marks the path of the roller 301, allowing the user to easily observe whether there are any obstacles along its path, maintaining the stability of the roller 301's movement, and consequently, maintaining the stability of the telescopic section 300's movement.

[0053] Optionally, the projector is mounted on the housing 200. This keeps the projector in a fixed position, better indicating the extension range of the telescopic section 300, making it easier for the user to clear obstacles within the entire extension range and maintaining the stability of the extension.

[0054] Optionally, the washing machine further includes a drive unit 600, disposed between the housing 200 and the telescopic part 300, configured to drive the telescopic part 300 to extend or retract. Thus, the drive unit 600 can more stably drive the telescopic part 300 to extend or retract, and more reliably drive the extension and retraction of the telescopic part 300.

[0055] Optionally, the drive device 600 includes a drive gear 601 and a rack 602. The drive gear 601 is disposed inside the housing 200 and driven by a motor 603, while the rack 602 is disposed on the side wall of the telescopic part 300 and meshes with the drive gear 601. The drive motor 603 drives the drive gear 601 to rotate, which in turn drives the rack 602 to move, thereby moving the telescopic part 300 and providing more stable drive for the telescopic part 300.

[0056] Optionally, the washing machine also includes a washing tub 700, located on the upper side of the casing 200. This allows for pre-washing of clothes in the washing tub 700 before placing them into the washing drum 400, improving cleaning efficiency and enhancing the user experience.

[0057] Combination Figure 7-10 As shown, this embodiment of the present disclosure provides a laundry basin 700, including: a basin body 100, with a water inlet 110 and a drain outlet 120 at the bottom. The water inlet 110 has a set angle and is configured to spray water from the set angle. Thus, the laundry basin 700 has a water inlet 110 and a drain outlet 120 at the bottom, allowing water to be added to or drained from the laundry basin 700. The water inlet 110 at the bottom of the laundry basin 700 has a set angle, allowing water to spray from the set angle, forming a rotating water wave within the laundry basin 700. When clothes are placed in the basin body 100, water is added through the water inlet 110. During the water addition process, the rotating water wave within the laundry basin 700 washes the clothes. After washing, the water in the basin body 100 can be drained through the drain outlet 120. The pre-washing process does not require user intervention, effectively reducing user labor.

[0058] Optionally, the inlet 110 is annular. In this way, setting the inlet 110 as annular expands the water injection range and makes it easier to form water waves.

[0059] Optionally, the annular water inlet 110 is located at the bottom of the basin 100, and its center overlaps with the center of the bottom of the basin 100. In this way, the water inlet 110 is arranged along the center of the bottom of the basin 100, which can make the water injection more uniform and form a stable water wave.

[0060] Optionally, the drain outlet 120 is located at the center of the bottom of the basin 100. In this way, by placing the drain outlet 120 at the center of the bottom of the basin 100, the water at the bottom of the basin 100 is more easily drained after the clothes are pre-washed.

[0061] Optionally, the water inlet 110 includes a plurality of nozzles 111, each nozzle 111 having a set angle and configured to spray water from the set angle. Thus, by providing a plurality of nozzles 111 at the water inlet and setting an angle for each nozzle 111, the rotation speed of the water waves in the basin can be increased by utilizing the water outlet angle of the nozzles 111, thereby improving the pre-washing effect of the clothes and shortening the pre-washing time.

[0062] Optionally, the multiple nozzles 111 are evenly distributed in a ring, with the center of the ring overlapping the center of the bottom of the basin 100. This makes the water flow more even when water is poured into the basin 100, which is convenient for pre-washing clothes.

[0063] Optionally, the angle is set to the angle between the line connecting the center of the nozzle 111 and the bottom of the basin 100 and the water outlet direction of the nozzle 111. In this way, the line connecting the center of the nozzle 111 and the bottom of the basin 100 is a line extending straight outward from the bottom of the basin 100. When the water outlet direction of the nozzle 111 forms an angle with this line, the water jet from the nozzle 111 can form a rotating water wave inside the basin 100, improving the pre-washing effect of clothes.

[0064] Optionally, the angle can be set to be greater than 0° and less than 90°. In this way, when the angle between the line connecting the center of the nozzle 111 and the bottom of the basin 100 and the water outlet direction of the nozzle 111 is greater than 0° and less than 90°, the water waves sprayed by the nozzle 111 can form rotating water waves within the basin 100, thus improving the pre-washing effect of clothes.

[0065] Optionally, the angle can be set to 45°. In this way, when the angle between the line connecting the center of the nozzle 111 and the bottom of the basin 100 and the water outlet direction of the nozzle 111 is 45°, the rotating water wave formed by the water jet from the nozzle 111 in the basin 100 has a greater rotational force, which is beneficial for pre-washing clothes.

[0066] Optionally, the angles of all the multiple spray heads 111 can be set to either clockwise or counterclockwise. In this way, by setting the angles of all the multiple spray heads 111 to either clockwise or counterclockwise, the water outlet direction of the spray heads 111 is clockwise or counterclockwise along the center point of the bottom of the basin 100, which facilitates the formation of clockwise or counterclockwise rotating water waves within the basin 100, thereby improving the pre-washing effect of clothes.

[0067] Optionally, some of the multiple nozzles 111 are set to a clockwise angle, while the rest are set to a counterclockwise angle. In this way, by spraying water sequentially from the nozzles 111 with different set angles, clockwise or counterclockwise rotating water waves are formed in the basin 100 at different times, which can change the direction of water wave rotation and improve the pre-washing effect of clothes.

[0068] Optionally, the spray nozzle 111 with a clockwise setting angle and the spray nozzle 111 with a counterclockwise setting angle alternately spray water. This alternating change in the direction of water wave rotation makes clothes cleaner.

[0069] Optionally, the washing basin 700 also includes a three-way valve. The inlet of the three-way valve is connected to a water source, one outlet of the three-way valve is connected to a spray head 111 with a clockwise setting angle, and the other outlet of the three-way valve is connected to a spray head 111 with a counterclockwise setting angle. In this way, by controlling the three-way valve to alternately supply water to the spray head 111 with a clockwise setting angle and the spray head 111 with a counterclockwise setting angle, the water flow can be changed clockwise or counterclockwise.

[0070] Optionally, the washing basin 700 further includes an ultrasonic generator 150 disposed within the basin body 100. Thus, by placing the ultrasonic generator 150 within the basin body 100, the resonance between ultrasonic waves and water molecules can enhance the activity of water molecules within the basin body 100, allowing water molecules to fully contact the clothes and improving the pre-washing effect.

[0071] Optionally, the ultrasonic generator 150 has a built-in ultrasonic generator that can produce ultrasonic vibrations.

[0072] Optionally, the ultrasonic generator 150 is embedded and fixed to the inner wall of the basin 100. In this way, since the ultrasonic generator 150 will resonate with the basin 100 during operation, embedding and fixing the ultrasonic generator 150 to the inner wall of the basin 100 is more secure and less likely to fall off during operation.

[0073] Optionally, the ultrasonic generator 150 is embedded and fixed to the inner wall of the bottom of the basin 100. In this way, fixing the ultrasonic generator 150 to the bottom of the basin 100 makes it easier for the ultrasonic waves emitted by the ultrasonic generator 150 to come into contact with the inner wall of the basin 100 and be reflected, which is beneficial to the propagation of the ultrasonic waves emitted by the ultrasonic generator 150 within the basin 100 and helps to improve the pre-washing effect of clothes.

[0074] Optionally, the ultrasonic generator 150 is located around the water outlet at the bottom of the basin 100. Fixing the ultrasonic generator 150 around the water outlet at the bottom of the basin 100 allows the ultrasonic waves emitted by the ultrasonic generator 150 to better penetrate and propagate into the washing water within the basin 100, thereby resonating with the water sprayed from the outlet and improving the pre-washing effect of the clothes.

[0075] Optionally, a protective cover 140 is provided on the basin 100, configured to cover the opening of the basin 100. In this way, by providing a protective cover 140 on the basin 100 to cover the opening, water inside the basin 100 will not splash out of the basin 100 when clothes are pre-washed, thus protecting the cleanliness of the outside of the basin 100.

[0076] Optionally, a sealing ring 141 is provided on the portion of the protective cover 140 corresponding to the opening of the basin 100. In this way, the protective cover 140 can completely cover and protect the opening of the basin 100, and can seal the basin 100 when the protective cover 140 covers the opening of the basin 100.

[0077] Optionally, the protective cover 140 is provided with a pivot 142 at one end. This allows the protective cover 140 to rotate along the pivot 142, thereby opening or closing the basin 100.

[0078] Optionally, the protective cover 140 is made of a transparent material. In this way, the protective cover 140, made of transparent material, allows the user to observe the pre-washing status of the underwear in the basin 100 during pre-washing without having to open the protective cover 140, thus saving the user's effort.

[0079] Optionally, the transparent material includes tempered glass. Thus, the protective cover 140 made of tempered glass is strong and not easily damaged, and has good transparency, making it easy to use.

[0080] Optionally, a return water inlet 130 is provided at the upper part of the basin 100. In this way, the washing water in the upper part of the basin 100 can be returned and reused through the return water inlet 130 during the pre-washing of clothes, reducing water waste and saving energy and protecting the environment.

[0081] Optionally, the return water outlet 130 is a linear return water outlet that surrounds the upper part of the basin 100. In this way, due to the surface tension of the liquid, lint, dust and other dirt often float on the liquid surface. The linear return water at the top of the basin 100 helps to filter out the dirt floating on the liquid surface, which can better filter and save water, and improve the pre-washing effect of clothes.

[0082] Optionally, the linear return inlet is located at the upper rim of the basin 100 and surrounds the rim of the basin 100. This positions the return inlet 130 at the highest point, allowing the basin 100 to hold more water and improving the space utilization of the basin 100.

[0083] Combination Figure 11-13 In some optional embodiments, the linear return water outlet includes a return water tank 131 and a collection water tank 132, and the return water tank 131 and the collection water tank 132 are connected. In this way, through the connection between the return water tank 131 and the collection water tank 132, water is returned through the return water tank 131 and collected and discharged through the collection water tank 132, which is beneficial for water filtration.

[0084] Optionally, the return water trough 131 is configured as a linear trough. In this way, configuring the return water trough 131 as a linear trough facilitates the installation of the return water trough 131 around the basin body 100.

[0085] Optionally, a sludge storage box 133 is provided at the outlet of the water collection tank 132. This facilitates the filtration and removal of sludge from the water flowing through the sludge storage box 133, thereby improving the filtration and removal efficiency.

[0086] Optionally, the sludge storage box 133 is detachably installed at the outlet of the water collection tank 132. This detachable design allows for easy removal of the sludge storage box 133 to clean the stored waste, resulting in more efficient sludge removal.

[0087] Optionally, the sludge storage box 133 includes a flow guide 134 and a filter screen 135, and the flow guide 134 is connected to the outlet of the water collection tank 132. In this way, water in the water collection tank 132 enters the sludge storage box 133 through the flow guide 134 and is filtered by the filter screen 135 located in the sludge storage box 133, which facilitates the filtration and removal of dirt from the water passing through the sludge storage box 133.

[0088] Optionally, the filter screen 135 is disposed inside the sludge storage box 133 at one end of the water outlet of the sludge storage box 133. In this way, the water flowing through the sludge storage box 133 is filtered by the filter screen 135, and the sludge filtered by the filter screen 135 is stored in the sludge storage box 133 for easy disposal.
