The drum washing device continuously rotates the drum, and the clothes fall on the drum and are beaten to achieve the effect of washing and cleaning. The core feature of the pulsator washing device is that there is a pulsator at the bottom of the washing tub. This pulsator can drive the clothes to turn up and down and left and right in the water by rotating forward and reverse.

[0064] Embodiment 1

[0065] Please refer to Figure 1-15As shown, this embodiment provides a flip-top washing device, including a washing tub mechanism 1, a water inlet mechanism 2, a drainage mechanism 3 and a driving mechanism 4. The washing tub mechanism 1 includes an outer frame 11 and an inner cylinder 17, the inner cylinder 17 is detachably arranged in the outer frame 11, a water outlet pipe 172 is arranged at the bottom of the inner cylinder 17, and the water outlet pipe 172 passes through the outer frame 11 and extends outward. In this embodiment, a water outlet channel 14 is opened at the bottom of the outer cylinder, and the water outlet pipe 172 passes through the water outlet channel 14 and extends outward. The driving mechanism 4 includes a driving assembly 41 and a driving block 42 connected to the driving assembly 41. The bottom of the outer frame 11 is fixed on the driving block 42; the driving block 42 is provided with an installation channel 421, and the end of the water outlet pipe 172 extends into the installation channel 421. The drainage mechanism 3 is arranged below the driving block 42 and extends into the installation channel 421, and the end of the water outlet pipe 172 is plugged into the drainage mechanism 3. The water inlet mechanism 2 is connected to the external water tank, and the water outlet of the water inlet mechanism 2 is connected to the washing tub mechanism 1 .

[0066] The water inlet mechanism 2 supplies water to the washing tub mechanism 1. The inner drum 17 is embedded in the outer frame 11, and the inner drum 17 can be quickly replaced to avoid cross-infection of bacteria and fungi on clothing items. The driving assembly 41 drives the driving block 42 to rotate, thereby driving the outer frame 11 to rotate. The inner drum 17 is located inside the outer frame 11 and rotates with the outer frame 11 to achieve washing of the internal clothes. The drainage mechanism 3 discharges the internal sewage of the washing tub mechanism 1.

[0067] Please refer to Figure 4 and Figure 12-15 As shown, specifically, the drainage mechanism 3 includes a quick-release drainage assembly 31, a drainage connector 32 and a drainage pump 33. The quick-release drainage assembly 31 is embedded in the installation channel 421, and the water outlet pipe 172 is plugged into the quick-release drainage assembly 31. The top of the drainage connector 32 is connected to the quick-release drainage assembly 31, and the drainage pump 33 is arranged at the bottom of the drainage connector 32. The quick-release drainage assembly 31 is embedded in the installation channel 421, which reduces the complexity of the connection structure between the quick-release drainage assembly 31 and the driving block 42, and the quick-release drainage assembly 31 can be quickly taken out for cleaning and replacement when the inner cylinder 17 is detached.

[0068] Specifically, the quick-release drainage assembly 31 includes a core 311 and a constant-pressure drainage valve. The core 311 is embedded in the installation channel 421. The core 311 is provided with a drainage channel 316. The outlet pipe 172 is inserted in the drainage channel 316 and communicates with the drainage channel 316. The constant-pressure drainage valve includes a valve body 317, a valve core 318, and a reset member 319. The valve body 317 is embedded in the drainage channel 316. An upper drainage port 3171 is provided at the top of the valve body 317. A guide channel 3174 and a lower drainage port 3173 are provided at the bottom of the valve body 317. The upper drainage port 3171 and the guide channel 3174 are located in the same extension direction. The valve core 318 includes a valve head 3181 and a valve stem 3183, the valve head 3181 and the valve stem 3183 are located in the internal cavity 3175 of the valve body 317, the top end of the valve stem 3183 is connected to the valve head 3181, the bottom end of the valve stem 3183 passes through the guide channel 3174 and extends to the drainage connector 32; the reset member 319 is arranged around the valve stem 3183, the top and bottom ends of the reset member 319 are respectively against the valve head 3181 and the valve body 317, and the reset member 319 pushes the valve head 3181 and the upper drainage port 3171 to press against each other. In this embodiment, the reset member 319 is a spring, and can also be other elastic structures. The drainage pump 33 uses negative pressure to pull the valve core 318 downward to compress the reset member 319, open the upper drainage port 3171, and achieve drainage. After the water pump 21 stops working, the reset member 319 drives the valve head 3181 upward to abut against the lower opening of the upper drainage port 3171, thereby sealing the upper opening and stopping drainage. During the control process, there is no need to connect the valve body 317, and the drainage efficiency is high. By adapting springs of different specifications, the water pressure that the constant pressure drainage valve can withstand can be flexibly adjusted. When drainage is required, only a small suction force is applied by the external control device to achieve drainage.

[0069] Please refer to Fig.14 As shown, further, the top of the valve head 3181 is provided with a lower fitting surface 3182, which is inclined outward from the inner side of the top surface of the valve head 3181 to the outer side of the lower part of the valve head 3181; the lower opening of the upper drain port 3171 is provided with an upper fitting surface 3172, which is inclined and has the same inclination angle as the lower fitting surface 3182. The inclined lower fitting surface 3182 and the upper fitting surface 3172 effectively increase the contact area between the valve head 3181 and the upper drain port 3171, improve the sealing effect of the upper drain port 3171, and prevent water leakage during the water storage process.

[0070] Further, there are multiple lower drain ports 3173, which are arranged around the guide channel 3174. In this embodiment, there are four lower drain ports 3173, which are arranged around the guide channel 3174 at intervals, so as to improve the drainage efficiency of the valve body 317 while ensuring that the valve body 317 has good structural strength. Similarly, more lower drain ports 3173 or fewer lower drain ports 3173 can be provided. In this embodiment, the upper end of the lower drain port 3173 extends to the upper part of the valve body 317, so as to increase the opening size of the lower drain port 3173 and further improve the drainage efficiency of the valve body 317.

[0071] In this embodiment, a first limiting convex ring 3162 is provided at the lower part of the drainage channel 316, and the constant pressure drainage valve is embedded in the drainage channel 316, and the bottom surface of the constant pressure drainage valve and the top surface of the first limiting convex ring 3162 are mutually abutted. The first limiting convex ring 3162 supports the constant pressure drainage valve, and ensures the stability of the constant pressure drainage valve during the air extraction process of the drainage pump 33. At the same time, the constant pressure drainage valve and the core body 311 are also connected in an embedded manner, and no other connection structure is required, which further reduces the difficulty of assembly and cleaning of the internal structure of the quick-disassembly drainage structure.

[0072] In this embodiment, an inner sealing ring 313 is provided at the upper part of the drainage channel 316, and the outlet pipe 172 is inserted into the drainage channel 316, and the inner sealing ring 313 is arranged around the circumference of the outlet pipe 172. The inner sealing ring 313 seals the circumference of the outlet pipe 172 to effectively prevent water from flowing back. Further, an inner sealing groove 3161 is provided at the upper part of the drainage channel 316, and the inner sealing ring 313 is embedded in the inner sealing groove 3161. The inner sealing groove 3161 limits the inner sealing ring 313 to ensure the stability of the inner sealing ring 313 during use. At the same time, the inner sealing ring 313 only needs the groove body to limit the position, and does not need an additional connection structure to connect the inner sealing ring 313. Under the premise of ensuring the reliability of the installation of the inner sealing ring 313, the cost is saved, and the quick disassembly and assembly between the inner sealing ring 313 and the core body 311 are realized, and the cleaning difficulty of the quick disassembly drainage structure is further reduced.

[0073] In this embodiment, the inner sealing ring 313 includes an inner body 3131, and a first sealing arm 3132 and a second sealing arm 3133 are provided at both ends of the bottom of the inner body 3131. The first sealing arm 3132 and the second sealing arm 3133 are distributed in an "eight" shape, and the bottom end of the first sealing arm 3132 is in contact with the top of the groove body of the inner sealing groove 3161, and the bottom end of the second sealing arm 3133 is in contact with the top of the side wall of the water outlet pipe 172. The first sealing arm 3132 is inclined toward the groove body structure of the inner sealing groove 3161. In the assembled state, the first sealing arm 3132 applies a force to the inner body 3131 and the second sealing arm 3133 in the direction of the water outlet pipe 172, ensuring the contact tightness between the second sealing arm 3133 and the water outlet pipe 172, and improving the internal sealing effect. The bottom end of the second sealing arm 3133 is inclined toward the water outlet pipe 172, which effectively increases the contact area between the second sealing arm 3133 and the water outlet pipe 172 in the assembled state, and further improves the internal sealing effect.

[0074] Furthermore, an outer sealing ring 312 is provided on the peripheral side of the core 311, and the outer sealing ring 312 is interference-fitted between the outer side surface of the core 311 and the inner side wall of the installation channel 421. The outer sealing ring 312 provides a limiting force for the core 311 in the installation channel 421, ensuring the stability of the core 311 during the drainage process. At the same time, the outer sealing ring 312 ensures the airtightness below the core 311, improving the accuracy of drainage control and water storage control. Specifically, an outer sealing groove 315 is provided on the outer side surface of the core 311, and the outer sealing ring 312 is embedded in the outer sealing groove 315, and the end of the outer sealing ring 312 protrudes from the notch of the outer sealing groove 315. The outer sealing groove 315 limits the outer sealing ring 312, and no additional connection structure is required to connect the outer sealing ring 312. Under the premise of ensuring the reliability of the installation of the outer sealing ring 312, the cost is saved, and the quick disassembly and assembly between the outer sealing ring 312 and the core 311 is realized, further reducing the difficulty of cleaning the quick-disassembly drainage structure. The end of the outer sealing ring 312 protrudes from the notch of the outer sealing groove 315. In the assembled state, the outer sealing ring 312 provides a limiting force to the core 311, ensuring the stability of the core 311, and at the same time ensuring the airtightness between the upper and lower parts of the core 311, improving the pumping effect of the drainage pump 33 on the valve core 318.

[0075] In this embodiment, a filter screen 314 is provided in the drainage channel 316 . The filter screen 314 is located above the upper drainage port 3171 . The filter screen 314 filters the discharged waste water to prevent impurities from affecting the operation of the constant pressure drainage valve and the drainage pump 33 .

[0076] Please refer to Figure 1-3As shown, further, the flip-top washing device also includes a lower mounting plate 6, on which a bearing seat 61 is fixed, and a driving block 42 is arranged on the lower mounting plate 6 and connected to the bearing seat 61. The driving block 42 is rotatably arranged on the lower mounting plate 6 through the bearing seat 61, and rotates with the drive assembly 41. In this embodiment, a card slot 422 is provided on the peripheral side of the driving block 42, and a card block (not shown in the accompanying drawings) is provided between the bearing seat 61 and the driving block 42, and the card block limits the driving block 42, and a bearing group 62 is provided in the bearing seat 61, and the bearing group 62 provides axial and circumferential support force for the driving block 42 to ensure that the driving block 42 rotates stably. A fixing plate 63 is fixed on the bottom surface of the lower mounting plate 6, and a bending portion 631 is provided on the fixing plate 63, and the bending portion 631 makes way for the driving block 42 and is arranged around the bottom and side of the driving block 42. The upper part of the drain connector 32 is pressed against the mounting plate, and the lower part of the drain connector 32 passes through the fixing plate 63 and is connected to the drain pump 33. The top of the drain connector 32 extends into the mounting channel 421 and is spaced apart from the inner side wall of the mounting channel 421. A lower sealing ring 423 is provided in the mounting channel 421, and the lower sealing ring 423 is arranged around the circumference of the drain connector 32. The drain connector 32 and the driving block 42 are spaced apart from each other, and the drain connector 32 does not rotate with the driving block 42 during the washing process, thereby ensuring the stability of the connection between the drain connector 32 and the drain pump 33. At the same time, the circumference of the drain connector 32 is sealed by the lower sealing ring 423, and the lower sealing ring 423 and the outer sealing ring 312 jointly ensure that the mounting channel 421 has good air tightness, thereby ensuring that the drainage process and the water storage process can be switched stably. In this embodiment, the drainage connector 32 includes a connection block 321 and a connection pipe 322. The connection block 321 is pressed against the upper part of the bent portion 631 of the fixed plate 63.

In this embodiment, the driving motor 411 is fixed on the top surface of the mounting plate, and the driving end of the driving motor 411 extends downward through the mounting plate and is at the same horizontal height as the lower end of the driving block 42. The driving motor 411 controls the driving block 42 to rotate through the driving belt 412.

[0078] Please refer to Figure 5-8 As shown, further, an axial limiting portion 12 and a circumferential limiting portion are provided on the outer frame 11, and the axial limiting portion 12 abuts against the inner cylinder 17 in the axial direction, and the circumferential limiting portion abuts against the inner cylinder 17 in the circumferential direction. The inner cylinder 17 is embedded in the outer frame 11, and the outer frame 11 rotates under the drive of the driving mechanism 4. The inner cylinder 17 rotates synchronously with the inner cylinder 17 under the restriction of the circumferential limiting portion, and the clothes inside the inner cylinder 17 are washed; at the same time, the axial limiting portion 12 limits the inner cylinder 17 in the axial direction, ensuring that the inner cylinder 17 will not go up and fall off the outer frame 11 during the rotation process, ensuring a good washing effect, and the detachable connection between the inner cylinder 17 and the outer frame 11 is realized through the axial limiting portion 12, and the inner cylinder 17 is quickly replaced. In family use, multiple inner drums 17 can be rotated, and one person can use one drum to avoid cross infection of bacteria and fungi between clothes, or the inner drum 17 can be discarded and replaced after a single use, or after multiple uses, the inner drum 17 can be discarded and replaced, and the use cycle of the inner drum 17 can be flexibly adjusted according to the use requirements. Specifically, the circumferential limiting portion includes at least one group of mutually corresponding first limiting protrusions 13 and first limiting grooves 171, the first limiting protrusions 13 are arranged on the inner side of the outer frame 11, the first limiting grooves 171 are arranged on the outer side of the inner drum 17, and the first limiting protrusions 13 are embedded in the first limiting grooves 171. In this embodiment, the number of the first limiting protrusions 13 and the first limiting grooves 171 is four groups, and the four groups of the first limiting protrusions 13 and the first limiting grooves 171 are respectively distributed at the two ends of the two mutually perpendicular diameters of the outer frame 11 and the two ends of the two mutually perpendicular diameters of the inner drum 17, ensuring that the outer frame 11 provides a uniform circumferential limiting force for the inner drum 17, and the inner drum 17 is more stably limited.

[0079] Furthermore, the washing tub mechanism 1 also includes a spin-drying tub 18, a first limiting groove 171 is located on the inner side of the inner drum 17 to form a second limiting protrusion 173, and a second limiting groove 181 is provided on the outer side of the spin-drying tub 18, which is recessed inward, and the second limiting protrusion 173 is embedded in the second limiting groove 181. The second limiting protrusion 173 axially limits the spin-drying tub 18, so that the spin-drying tub 18 rotates synchronously with the inner drum 17 and the outer frame 11. The side wall and the bottom plate 182 of the spin-drying tub 18 are both provided with a first drain port 183, and the first drain ports 183 are distributed in an array on the side wall and the bottom plate 182 of the spin-drying tub 18. The first drain port 183 connects the spin-drying tub 18 and the inner drum 17, so that the water in the spin-drying tub 18 is diverted to the inner drum 17, and finally discharged through the outlet pipe 172, so as to achieve the effect of drying.

[0080] In this embodiment, a convex eave 185 extending outward is provided on the top surface of the spin-drying barrel 18, and the end surface of the convex eave 185 is in contact with the inner side wall of the inner tube 17. The convex eave 185 supports the spin-drying barrel 18, and at the same time, the side wall of the spin-drying barrel 18 and the inner side surface of the inner tube 17 are arranged at intervals, so that the water in the spin-drying barrel 18 flows out from the side wall of the spin-drying barrel 18, thereby improving the spin-drying effect. Furthermore, a plurality of drainage notches 1851 arranged at intervals are provided at the end of the convex eave 185. The drainage notches 1851 allow the accumulated water on the convex eave 185 to be smoothly discharged into the inner tube 17, thereby avoiding the residual water and affecting the spin-drying effect. Similarly, the top surface of the convex eave 185 can be set to an inclined surface 1212 that tilts downward from the outside to the inside, so that the water on the convex eave 185 is discharged into the inside of the spin-drying barrel 18 and discharged through the first drainage port 183 of the spin-drying barrel 18.

[0081] Furthermore, a plurality of second drain ports 184 are provided at intervals at the bottom of the side wall of the spin drying tub 18, and the bottom of the second drain ports 184 extends to the end of the bottom plate 182 of the spin drying tub 18. The top of the second drain ports 184 is located at the bottom of the side wall of the spin drying tub 18, and the bottom of the second drain ports 184 is located at the end of the bottom plate 182 of the spin drying tub 18. The second drain ports 184 drain the accumulated water at the connection position between the side wall of the spin drying tub 18 and the bottom plate 182, thereby preventing water from accumulating at the bottom of the side wall of the spin drying tub 18 during the spin drying process, and further improving the spin drying effect.

[0082] In this embodiment, the bottom of the inner drum 17 is funnel-shaped, and the water outlet pipe 172 is located at the center of the bottom of the inner drum 17. The funnel-shaped bottom of the inner drum 17 guides the water in the inner drum 17 and drives the water to flow toward the water outlet pipe 172, thereby improving the drainage efficiency. A plurality of support columns 186 are arranged at intervals on the bottom surface of the spin-drying barrel 18, and the ends of the support columns 186 abut against the inner bottom surface of the inner drum 17. The support columns 186 raise the bottom surface of the spin-drying barrel 18, so that the bottom surface of the spin-drying barrel 18 is spaced apart from the bottom surface of the inner drum 17, thereby facilitating the drainage of water. In this embodiment, a plurality of support columns 186 are arranged at intervals at the edge of the bottom surface of the spin-drying barrel 18. The support columns 186 are arranged at the edge to reduce the obstruction to the water flow, thereby further improving the drainage efficiency of the disposable washing bucket.

[0083] In this embodiment, the first limiting protrusion 13, the first limiting groove 171, the second limiting protrusion 173 and the second limiting groove 181 all extend in the height direction of the outer frame 11. The first limiting protrusion 13, the first limiting groove 171, the second limiting protrusion 173 and the second limiting groove 181 are arranged relatively high, so that the outer frame 11, the inner drum 17 and the spin-drying tub 18 have a larger contact surface during the rotation process, thereby improving the driving effect of the inner drum 17 and the spin-drying tub 18, and ensuring that the inner drum 17 and the spin-drying tub 18 rotate synchronously with the outer frame 11.

[0084] Furthermore, an axial limiting portion 12 is provided at the top of the outer frame 11, and the axial limiting portion 12 protrudes toward the inner cylinder 17 and abuts against the top of the inner cylinder 17. The axial limiting portion 12 limits the axial position of the inner cylinder 17 to ensure that the inner cylinder 17 rotates stably in the outer frame 11.

[0085] Specifically, the axial limiting portion 12 includes a limiting block 121, and a snap-fitting groove 1211 is provided on the inner side surface of the limiting block 121. A snap-fitting plate 174 extending outward is provided on the top of the inner cylinder 17, and the end of the snap-fitting plate 174 is embedded in the snap-fitting groove 1211. The inner cylinder 17 uses its own elasticity to achieve the snap-fitting and separation between the snap-fitting plate 174 and the snap-fitting groove 1211, and the purpose of the inner cylinder 17 being detachable is achieved under the premise of ensuring that the axial limiting portion 12 has a good limiting effect. Further, the inner side surface of the limiting block 121 is an inclined surface 1212, and the inner side surface is inclined outward from the top toward the inner cylinder 17 to the notch of the snap-fitting groove 1211. The inclined surface 1212 guides the snap-fitting plate 174 of the inner cylinder 17, so that the snap-fitting plate 174 can enter the snap-fitting groove 1211 more easily.

[0086] In this embodiment, the outer frame 11 is provided with an assembly notch 15, and the bottom of the assembly notch 15 is located below the clamping plate 174. The assembly notch 15 makes way for the top of the inner cylinder 17, so that the hand can pass through the assembly notch 15 to apply force to the inner cylinder 17, thereby facilitating the installation and removal of the inner cylinder 17. Figure 8As shown, further, a plurality of weight reduction channels 16 are provided on the outer frame 11, and the plurality of weight reduction channels 16 are arranged at intervals on the peripheral side of the outer frame 11.

A longer connecting handle 731 is provided to ensure that the inner cover 73 can be stably covered on the outer frame 11 and the inner drum 17, and the driving spring 732 provides the inner cover 73 with a thrust in the direction of the outer frame 11 and the inner drum 17 above the inner cover 73, so that the inner cover 73, the outer frame 11 and the inner drum 17 fit more closely, further improving the limiting effect of the upper cover assembly 7 on the outer frame 11 and the inner drum 17. At the same time, the inner cover 73 rotates synchronously with the outer frame 11 and the inner drum 17 through the bearing, and limits the outer frame 11 at the upper part of the outer frame 11, thereby improving the rotation stability of the outer frame 11 and the inner drum 17 during the washing process and reducing the washing noise.

In this embodiment, the structure of the flip-top washing device is the same as that of the flip-top washing device in the first embodiment. The difference is that in this embodiment, a plurality of spin-drying convex ribs 175 are arranged at intervals on the inner side surface of the inner drum 17. A plurality of spin-drying convex strips 176 are arranged on the inner bottom surface of the inner drum 17, and the spin-drying convex strips 176 are arranged around the upper opening of the water outlet pipe 172.
