[0042] In related technologies, when washing equipment such as drum washing machines wash clothes, dirt in the washing water can easily remain on the irregular surface of the inner drum, polluting the washing environment and affecting the subsequent washing effect. Existing washing equipment has a cleaning structure to clean the inner drum, but its cleaning effect on the outer wall of the inner drum is not good.

[0043] This application provides a washing device to address the shortcomings of existing washing devices in effectively cleaning dirt from the outer wall of the inner drum. The following will be discussed in conjunction with the accompanying drawings. Figures 1-5 Please provide an explanation.

[0044] The washing equipment provided in the embodiments of this application refers to... Figure 1 and Figure 2 As shown, it includes an inner cylinder 100, an outer cylinder 200, and a water inlet pipe 300. The outer cylinder 200 is sleeved on the outside of the inner cylinder 100. The water inlet pipe 300 is connected to the outer cylinder 200. The water inlet pipe 300 is provided with a plurality of nozzles 310 at intervals along its extension direction. The water outlet of the nozzles 310 is set towards the outer wall of the inner cylinder 100. For example, the water outlet of the nozzles 310 can be set towards the outer wall end face 101 of the inner cylinder 100, or it can be set towards the outer wall side of the inner cylinder 100, so as to thoroughly clean the outer wall surface of the inner cylinder 100.

[0045] It is understood that the washing equipment in this embodiment can be a drum washing machine, a top-loading washing machine, a washer-dryer combo, or other washing equipment. The outer drum 200 is sleeved outside the inner drum 100, and the inner drum 100 can be rotatably mounted on the outer drum 200 to facilitate washing and spin-drying of clothes.

[0046] The washing device provided in this application includes an inner drum 100, an outer drum 200, and a water inlet pipe 300. The outer drum 200 is sleeved outside the inner drum 100, and the water inlet pipe 300 is connected to the outer drum. Multiple nozzles 310 are spaced apart along the extension direction of the water inlet pipe 300, with the outlets of the nozzles 310 facing the outer wall 101 of the inner drum 100. By spaced apart multiple nozzles 310 along the extension direction of the water inlet pipe 300, the nozzles 310 can cover as much of the outer wall of the inner drum 100 as possible, including but not limited to the outer wall end face 101 and the outer wall side of the inner drum 100, achieving comprehensive cleaning of the outer wall of the inner drum 100 and significantly improving the cleaning effect.

[0047] In one alternative implementation, refer to Figure 1 and Figure 2 As shown, the water inlet pipe 300 is spirally coiled around the inner wall end face 201 of the outer cylinder 200, and the water outlet of the nozzle 310 is set towards the outer wall end face 101 of the inner cylinder 100.

[0048] It is understandable that the connection structure of the inner cylinder 100 is mainly concentrated at the outer wall end face 101 of the inner cylinder 100. The outer wall end face 101 has a lot of irregular surfaces, so dirt is also mainly concentrated at the outer wall end face 101 of the inner cylinder 100.

[0049] In this embodiment, the water inlet pipe 300 can be located in the gap between the inner cylinder 100 and the outer cylinder 200, and is spirally coiled (similar to the coiled arrangement of a mosquito coil) on the inner wall end face 201 of the outer cylinder 200, so that the water inlet pipe 300 can fit tightly against the inner wall of the outer cylinder 200, while providing an installation position for the nozzle 310. The water inlet pipe 300 is provided with multiple nozzles 310 at intervals along its extension direction (i.e., the spiral direction). The outlet of the nozzles 310 faces the outer wall end face 101 of the inner drum 100, ensuring that the water flow sprayed from the outlet of the nozzles 310 can directly cover all corners of the outer wall end face 101 of the inner drum 100. This reduces the cleaning dead angles of the connecting structures on the outer wall end face 101 of the inner drum 100, achieves comprehensive cleaning of the outer wall end face 101 of the inner drum 100, improves the cleaning effect, reduces the residue of dirt on the inner drum 100, reduces the possibility of dirt growth, avoids mold, and ensures the washing equipment's cleaning ability and health and safety performance.

[0050] For example, the water inlet end 301 of the water inlet pipe 300 can be connected to the water storage box of the washing equipment or an external water inlet device to provide water to the water inlet pipe 300 for cleaning the inner wall.

[0051] It should be noted that the attached drawings only show the case where the water inlet pipe 300 is wound into two loops. The water inlet pipe 300 can also be wound into three, four or more loops as needed, or the water inlet pipe 300 can be extended to the center area of ​​the outer cylinder 200 to achieve a complete cleaning of the inner cylinder 100. This embodiment does not impose specific limitations on this.

[0052] In one alternative implementation, refer to Figure 1 and Figure 3 As shown, the washing equipment also includes a tripod 400, which connects the inner tub 100 and the outer tub 200, and at least a portion of the nozzles 310 have their outlets facing the tripod 400.

[0053] Understandably, to improve the stability of washing equipment during operation, a tripod 400 is typically installed to connect the inner drum 100 and the outer drum 200. As the main connecting structure at the outer wall end face 101 of the inner drum 100, the tripod 400 is particularly prone to accumulating dirt in its grooves, crevices, and corners. By aligning at least a portion of the nozzles 310's outlets towards the tripod 400 area, dirt can be removed more effectively, ensuring the cleanliness of the connection between the tripod 400 and the inner drum 100 and reducing the possibility of bacterial growth.

[0054] In one alternative implementation, refer to Figure 1 and Figure 3 As shown, a drive shaft 210 is provided on the end face of the outer cylinder 200. The drive shaft 210 is rotatably mounted on the outer cylinder 200, and one end of the drive shaft 210 away from the inner cylinder 100 is used to connect to the drive device, while the other end is connected to the tripod 400.

[0055] For example, a bearing seat 220 is fixedly installed on the end face of the outer cylinder 200, and the drive shaft 210 is installed on the bearing seat 220 through the bearing 230. One end of the drive shaft 210 is connected to a drive device (e.g., a motor), and the other end of the drive shaft 210 is fixedly installed on the tripod 400. The inner cylinder 100 is fixedly installed on the tripod 400 by screws, so that the drive device can drive the inner cylinder 100 to rotate through the drive shaft 210.

[0056] Furthermore, a circular hole is provided on the side wall of the inner drum 100, which connects the space inside the inner drum 100 and the outer drum 200, allowing washing water inside the outer drum 200 to enter and exit the interior of the inner drum 100 through the circular hole. Multiple circular holes can be provided, and these holes can be spaced apart along the axial direction and / or circumferential direction of the inner drum 100.

[0057] When the washing machine is washing clothes, there is a large amount of washing water inside the outer drum 200. The drive shaft 210 transmits the power of the drive device to the tripod 400, thereby driving the inner drum 100 to rotate. Dirt in the clothes can enter the washing water inside the outer drum 200 through the round holes on the side wall of the inner drum 100.

[0058] In one optional embodiment, the number of nozzles 310 corresponding to the middle region of the water inlet pipe 300 is greater than the number of nozzles 310 corresponding to the outer ring region of the water inlet pipe 300, that is, the number of nozzles 310 in the middle region of the disc-shaped spiral formed by the water inlet pipe 300 is greater than the number in the outer region.

[0059] Understandably, the central area of ​​the inner cylinder 100 is where the tripod 400 connects to the drive shaft 210, and where all the legs of the tripod 400 connect, making it very prone to dirt buildup. By increasing the number of nozzles 310 in the central area, the dirt at the connection between the tripod 400 and the drive shaft 210 can be cleaned directly, improving cleaning effectiveness and efficiency.

[0060] In one alternative implementation, refer to Figure 2 As shown, along the extension direction of the water inlet pipe 300, the spacing between adjacent nozzles 310 gradually decreases. That is, from the water inlet end 301 of the water inlet pipe 300 to the other end, the distribution of nozzles 310 becomes more and more dense, so as to perform a more thorough cleaning of the middle area of ​​the inner cylinder 100 and improve the cleaning effect.

[0061] In one alternative implementation, refer to Figure 1 and Figure 5 As shown, the end face of the outer cylinder 200 is provided with a through hole 202, and the water inlet end 301 of the water inlet pipe 300 passes through the through hole 202 and is connected to the water inlet device.

[0062] In this embodiment, the through hole 202 is used for the water inlet end 301 of the water inlet pipe 300 to pass through. After the water inlet end 301 of the water inlet pipe 300 passes through the through hole 202, it is connected to the water inlet device. The water inlet device can be the water storage box of the washing equipment or an external water source. For example, the water inlet pipe 300 can be connected to an external faucet to provide water flow for cleaning the inner drum 100.

[0063] The water inlet pipe 300 can be fixed to the outer cylinder 200 through the through hole 202 to enhance the stability of the pipe and prevent the water inlet pipe 300 from shifting during the water spraying process of the nozzle 310.

[0064] In one alternative implementation, refer to Figure 4 and Figure 5 As shown, the insertion hole 202 is located at the top of the outer cylinder 200, that is, the water inlet end 301 of the water inlet pipe 300 is located at the top of the outer cylinder 200, so that the water flows into the water inlet pipe 300 from the top. The water can be sprayed directly downward by utilizing the gravity of the water flow, which is beneficial to increase the water flow velocity from the nozzle 310, thereby improving the cleaning effect on the inner cylinder 100.

[0065] In an optional embodiment, a pipe clamp (not shown in the figure) is provided on the inner wall end face 201 of the outer drum 200, and the water inlet pipe 300 is fixed to the pipe clamp. By providing a pipe clamp on the end face of the inner wall of the outer drum 200 to fix and support the water inlet pipe 300, it can be ensured that the water inlet pipe 300 remains stable during washing and rinsing and will not shift due to excessive water pressure or vibration of the washing equipment.

[0066] Optionally, the pipe clamp can be a C-shaped clamp, which surrounds the outside of the inlet pipe 300 to fix the inlet pipe 300. The installation process is simple; the inlet pipe 300 is simply pressed into the C-shaped clamp to achieve fixation. Optionally, the pipe clamp may also include two semi-circular or U-shaped components, which are connected by screws to clamp the pipe, providing better stability.

[0067] In one optional embodiment, there are multiple pipe clamps, which are spaced apart along the extension direction of the water inlet pipe 300. This enhances the connection stability of the water inlet pipe 300 and ensures that the entire water inlet pipe 300 is evenly supported in the extension direction, so that the pressure is evenly distributed throughout the water inlet pipe 300, avoiding excessive local pressure and improving the safety performance of the washing equipment.

[0068] In an optional embodiment, the water inlet pipe 300 is provided with a snap-fit ​​component (not shown in the figure). The snap-fit ​​component can be a protrusion structure provided on the outside of the water inlet pipe 300. The inner wall end face 201 of the outer cylinder 200 is provided with a slot (not shown in the figure). The shape and size of the slot match the shape and size of the snap-fit ​​component. When the water inlet pipe 300 is installed on the outer cylinder 200, the snap-fit ​​component engages with the slot.

[0069] When installing the inlet pipe 300, align the snap-fit ​​connector with the slot and manually insert it. The installation process is simple and quick, requiring no complicated tools or additional fasteners. The connection is stable and not easily detached, ensuring the stability of the inlet pipe 300 during operation.

[0070] In one optional embodiment, there are multiple snap-fit ​​components, with multiple pipe clamps spaced apart along the extension direction of the water inlet pipe 300, and each snap-fit ​​component having a corresponding slot. This method of securing the water inlet pipe 300 with multiple snap-fit ​​components also improves the connection stability between the water inlet pipe 300 and the outer cylinder 200, preventing displacement of the water inlet pipe 300.

[0071] In an optional embodiment, the washing apparatus includes a controller configured to send control signals to the drive unit and water inlet unit of the washing apparatus during the draining phase and / or washing phase; the control signals are used to control the drive unit to drive the inner drum 100 to rotate and to control the water inlet unit to supply water flow into the water inlet pipe 300 to clean the inner drum 100.

[0072] Optionally, during the washing stage of the washing equipment, the water inlet device can be turned on and water can be introduced into the water inlet pipe 300 to clean the outer wall end face 101 of the inner drum 100. During this process, the rotation of the inner drum 100 can achieve a thorough cleaning of the outer wall end face 101 of the inner drum 100. Since the cleaning of the inner drum 100 can be completed during the washing process, it avoids spending extra time on cleaning, thus improving the convenience and comfort of using the washing equipment.

[0073] However, since the water in the inner drum 100 and the outer drum 200 is connected during the washing process, the lower end of the inner drum 100 may be immersed in washing water containing dirt. Dirt that falls off after cleaning the outer wall of the inner drum 100 during the washing process may re-enter the inner drum 100, affecting the washing effect on the clothes. Therefore, during the drainage stage of the washing equipment, the water inlet device can be opened and water flowed into the water inlet pipe 300. This, combined with the rotation of the inner drum 100, cleans the outer wall end face 101 of the inner drum 100. At this time, the water level in the outer drum 200 can be discharged through the drain pipe, resulting in a lower water level and preventing the wastewater from contaminating the clothes in the inner drum 100.

[0074] In an optional embodiment, the washing equipment also includes a booster pump (not shown in the figure), which is connected to the water inlet pipe 300 to increase the water inlet pressure of the water inlet pipe 300, ensuring that the water sprayed from the outlet of the nozzle 310 has sufficient pressure to wash away the dirt, thereby improving the cleaning effect and cleaning efficiency of the dirt on the outer wall end face 101 of the inner drum 100.

[0075] In one alternative implementation, the outlet angles of different nozzles 310 are different.

[0076] For example, the water outlet angle refers to the angle between the water outlet direction of the nozzle 310 and the axis of the inner cylinder 100, with the axis of the inner cylinder 100 as a reference. Different water outlet angles can ensure that the water flow is sprayed in multiple directions, thereby covering all corners of the inner cylinder 100. For example, some nozzles 310 can be designed to spray directly, while others can be designed to spray at an angle, so as to achieve multi-angle spraying and key area spraying on the outer wall end face 101 of the inner cylinder 100, improve the cleaning ability of the inner cylinder 100, and avoid dirt residue on irregular surfaces on the outer wall end face 101 of the inner cylinder 100.

[0077] In an optional embodiment, the nozzle 310 is provided with an adjustment section (not shown in the figure) for adjusting the water outlet angle of the nozzle 310.

[0078] For example, the adjustment part can be a knob, a gear and rack assembly, a threaded connection structure or other structure, that is, the nozzle 310 can rotate or turn relative to the water inlet pipe 300, and the water outlet angle of the nozzle 310 can be adjusted as needed to ensure comprehensive cleaning of the outer wall end face 101 of the inner cylinder 100.

[0079] In the above embodiments, the descriptions of each embodiment have different focuses. For parts not described in detail in a certain embodiment, please refer to the relevant descriptions in other embodiments.

[0080] Finally, it should be noted that the above embodiments are only used to illustrate this application and are not intended to limit this application. Although this application has been described in detail with reference to the embodiments, those skilled in the art should understand that various combinations, modifications, or equivalent substitutions of the technical solutions of this application do not depart from the spirit and scope of the technical solutions of this application and should all be covered within the protection scope of this application.
