Description

Technical Field

[0001] The present invention belongs to the field of clothing processing equipment, and in particular relates to a clothing processing equipment and a tripod thereof. Background Art

[0002] The inner and outer drums of a drum washing machine are the components most directly involved in washing clothes, coming into direct contact with clothes, water, and detergent. Therefore, after each wash cycle, dirt and lint easily accumulate on the inner drum's sidewalls, the rear of the outer drum, and especially on the rotating support at the rear of the inner drum. However, after assembly, the inner drum is at the very heart of the drum washing machine, making it particularly difficult to disassemble.

[0003] like Figures 1 to 3 The figure shows the assembly relationship between the inner drum, outer drum and tripod of a drum washing machine in the prior art. Figure 1 For the outer cylinder, from Figure 1 As can be seen from the figure, there are many cavities on the bottom 1' of the outer drum due to process requirements, and these parts are very likely to retain dirt during normal washing. Figure 2 This is the state after the inner tube 2' and the tripod 4' are installed. Figure 3 This exploded view shows the inner and outer cylinders 2' and 3'. The relationship between the three components, along with the tripod 4', is clearly visible. Furthermore, after the tripod 4' is assembled with the inner cylinder 2', numerous gaps form between them, allowing for the accumulation of dirt. Furthermore, the gap between the inner and outer cylinders 2' and 3' is extremely narrow, making it difficult to reach and clean.

For example, they may refer to fixed, detachable, or integral connections; mechanical or electrical connections; and direct or indirect connections through an intermediary. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0052] like Figures 4 to 8 As shown, the present invention provides a laundry processing device and a tripod thereof. Tripod 300 is an intermediate component that transmits force from the rotating shaft of the drum-type laundry processing device to the inner drum. It is generally a cast metal part. The structural strength of tripod 300 ensures the normal rotation of the inner drum and the efficient operation of the washing machine. The laundry processing device can be a drum washing machine or a washer-dryer. The present invention is mainly described using the example of tripod 300 used in a drum washing machine. However, this should not be construed as limiting the scope of protection of the present invention.

[0053] The tripod 300 of the present invention includes a main shaft connection portion 302 and a plurality of support arms 301 .

[0054] Specifically, if Figures 4 to 6 As shown, multiple support arms 301 are connected to the main shaft connection portion 302, and the multiple support arms 301 are spaced apart and arranged in a diverging pattern around the main shaft connection portion 302. For example, the multiple support arms 301 can be spaced apart and arranged around the main shaft connection portion 302, and the multiple support arms 301 can be arranged in a radial pattern extending outward from the main shaft connection portion 302. In this way, when the tripod 300 is used in a drum washing machine, it can provide a certain degree of support for the inner drum and help improve the reliability of the tripod 300.

[0055] The main shaft connection portion 302 may be in the form of a ring, such as a polygonal ring or a circular ring. Figure 4 In the illustrated embodiment of the present invention, a tripod 300 may include a main shaft connection portion 302 and three support arms 301 extending outward from the main shaft connection portion 302. The three support arms 301 may be evenly spaced apart in a direction surrounding the main shaft connection portion 302. This balances forces and improves the operational stability of the tripod 300.

[0056] Optionally, the support arms 301 may also include two, four, five, etc. The specific number and arrangement of the support arms 301 can be adaptively set as needed.

[0057] like Figure 6 As shown, the present invention provides interconnected water passages 303 within the spindle connection portion 302 and the support arm 301, and a spray nozzle assembly connected to the water passage 303 is provided on the sidewall 3013 of the support arm 301. The spray nozzle assembly on the support arm 301 can be used to clean the gap between the inner and outer tubs 200, eliminating the need for an additional cleaning unit for cleaning dirt between the inner and outer tubs 200, thereby reducing the cost of the laundry processing equipment.

[0058] In detail, control instructions for controlling the spraying process of the spray port assembly can be embedded in the washing program. For example, after the drainage instruction of the washing program is executed, a spray instruction for spraying using the spray port assembly is added. The spray port assembly is used to clean the space between the inner drum and the outer drum 200 and then the rinsing instruction is executed. This can increase the cleaning ratio of the washing program and improve the user experience.

[0059] Alternatively, the spray instruction for spraying using the spray port assembly can be embedded in the last instruction of the washing program, and the instruction for cleaning between the inner and outer drums 200 using the spray port assembly can be executed after dehydration and drainage to clean the dirt and lint remaining between the inner and outer drums 200, thereby achieving wash-as-you-use and avoiding dirt accumulation and bacterial growth.

[0060] In some embodiments of the present invention, the spray port assembly only includes the first spray port 3012 ; the first spray port 3012 is disposed on the bottom wall 3011 of the support arm 301 .

[0061] In detail, the support arm 301 includes a bottom wall 3011, which is connected to the spindle connection portion 302 and extends away from the spindle connection portion 302. Side walls 3013 are provided on either side of the bottom wall 3011, namely a first side wall and a second side wall. The first side wall and the second side wall are both connected to the bottom wall 3011 and extend in the same direction as the bottom wall 3011, and the first side wall and the second side wall are spaced apart in a direction surrounding the spindle connection portion 302.

[0062] After the tripod 300 is mounted on the bottom of the inner cylinder, the bottom wall 3011 of the support arm 301 is directly inside the outer cylinder bottom 201. In this embodiment, the first spray port 3012 is provided on the bottom wall 3011 of the support arm 301, and the outer cylinder bottom 201 can be cleaned by the first spray port 3012.

[0063] In further solutions, such as Figure 4 As shown, the first spray port 3012 is a strip-shaped opening, and the extending direction of the first spray port 3012 is consistent with the extending direction of the bottom wall 3011 .

[0064] In detail, the first spray port 3012 is configured as a strip-shaped opening, which can increase the coverage area of ​​the spray on the inner side of the outer cylinder bottom 201 and improve the cleaning efficiency.

[0065] In some embodiments of the present invention, Figure 5 As shown, the spray port assembly only includes the second spray port 3014 ; the second spray port 3014 is provided on the side wall 3013 of the support arm 301 .

[0066] In detail, the support arm 301 includes a bottom wall 3011, which is connected to the main shaft connection part 302 and extends in a direction away from the main shaft connection part 302. A first side wall and a second side wall are provided on both sides of the bottom wall 3011. The first side wall and the second side wall are both connected to the bottom wall 3011 and extend in the same direction as the bottom wall 3011, and the first side wall and the second side wall are spaced apart and arranged in a direction surrounding the main shaft connection part 302.

[0067] In this embodiment, the second spray port 3014 is arranged on the first side wall and the second side wall of the support arm 301. The second spray port 3014 can be used to clean the outside of the inner tube bottom (not shown in the figure) and the connection between the inner tube bottom and the tripod.

[0068] In a further solution, a plurality of second spray openings 3014 are provided on both the first side wall and the second side wall, and the plurality of second spray openings 3014 are staggeredly arranged on the first side wall and the second side wall.

[0069] In detail, the plurality of second spray ports 3014 arranged in staggered positions can clean the outer side of the bottom of the inner cylinder without any dead angles, thereby improving the cleaning effect.

[0070] In some embodiments of the present invention, the spray port assembly includes a first spray port 3012 and a second spray port 3014; the first spray port 3012 is arranged on the bottom wall 3011 of the support arm 301; the second spray port 3014 is arranged on the side wall 3013 of the support arm 301.

[0071] In detail, the first spray port 3012 and the second spray port 3014 can be used to clean the inner side of the outer cylinder bottom 201 and the outer side of the inner cylinder bottom, which can further prevent dirt such as lint from remaining in the gap between the inner cylinder and the outer cylinder 200.

[0072] In a further solution, the second spray port 3014 is a hole-shaped opening; preferably, the outlet direction of the second spray port 3014 is inclined away from the bottom wall 3011 .

[0073] In detail, the outlet direction of the second spray port 3014 is inclined away from the bottom wall 3011, that is, the outlet direction of the second spray port 3014 is inclined toward the bottom of the inner tube, and the second spray port 3014 has a stronger cleaning ability for the installation gap between the bottom of the inner tube and the tripod 300.

[0074] The clothing processing device of the present invention also includes a main shaft 400 with a hollow water channel 401 inside. The main shaft 400 is connected to the main shaft connecting part 302. One end of the hollow water channel 401 is connected to the water inlet pipe 500, and the other end is connected to the water flow channel 303.

[0075] It is understandable that a conversion joint should be provided between the water inlet pipe 500 and the main shaft 400 so that the water in the water inlet pipe 500 can enter the hollow water channel 401 of the main shaft 400 during the rotation of the main shaft 400.

[0076] Detailed, such as Figure 8 As shown, the clothing treatment device further includes a water inlet valve 501 , which is connected to the water inlet pipe 500 and is used to control the on-off flow of water in the water inlet pipe 500 .

[0077] When the instruction to spray using the spray port assembly is received, the water inlet valve 501 is opened, and the clean water enters the hollow water channel 401 of the main shaft 400 through the water inlet pipe 500 and then enters the water flow channel 303 of the tripod 300, and is then sprayed out through the first spray port 3012 and / or the second spray port 3014 set on the tripod 300 to clean the bottom of the inner cylinder and / or the bottom of the outer cylinder 201.

[0078] Furthermore, to enhance the cleaning effect of the spray, a power unit may be provided on the water inlet pipe 500 to provide power for the water flow and enhance the speed of the water flow ejected from the first spray port 3012 and / or the second spray port 3014. Preferably, the power unit includes a water pump 502.

[0079] Optionally, the drain valve can be opened while the water inlet valve 501 is opened, that is, the water containing dirt can be discharged during the spraying process.

[0080] In a further solution, the bottom wall 3011 of the outer cylinder 200 is provided with a third spray port 202 , and the third spray port 202 is communicated with the water inlet pipe 500 .

[0081] In detail, as described above, when the tripod 300 is installed outside the bottom of the inner cylinder, it is facing the bottom of the outer cylinder 201. Therefore, the present invention provides a third spray port 202 on the bottom wall 3011 of the outer cylinder 200, and uses the third spray port 202 to spray and clean the tripod 300 to prevent dirt and lint from remaining on the tripod 300.

[0082] Specifically, the bottom wall 3011 of the outer cylinder 200 is provided with a plurality of third spray ports 202, which are radially arranged on the bottom wall 3011 of the outer cylinder 200. Preferably, the bottom wall 3011 of the outer cylinder 200 is provided with three radially distributed third spray ports 202. As the inner cylinder and the tripod 300 rotate, clean water is sprayed toward the bottom of the inner cylinder and the tripod 300 through the radially distributed third spray ports 202, thereby cleaning the bottom of the inner cylinder and the tripod 300.

[0083] At this time, the strip-shaped first spray port 3012 on the bottom wall 3011 of the support arm 301 is used to clean the inside of the outer cylinder bottom 201; the circular hole-shaped second spray port 3014 on the side wall 3013 of the support arm 301 is used to clean the outside of the inner cylinder bottom and the installation gap between the inner cylinder and the tripod 300; and the third spray port 202 on the wall of the outer cylinder bottom 201 can clean the tripod and the side wall 3013 of the outer cylinder 200. This arrangement allows for comprehensive cleaning of the outer cylinder 200, inner cylinder, and tripod 300.

[0084] When cleaning is performed, the water inlet valve 501 is opened, and the water pump 502 pressurizes the water and pumps it to the outer cylinder 200 and the nozzles on the tripod 300, while controlling the tripod 300 and the inner cylinder to rotate to form a spraying area.

[0085] The above description is merely a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as above in terms of a preferred embodiment, it is not intended to limit the present invention.
