Figure 1 and attached Figure 6 The orientation or positional relationship shown, the "circumferential" orientation or positional relationship is based on the attached... Figure 2 It should be understood that these directional terms are only for the convenience of describing this application and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0033] This invention provides a bucket bottom 10, see reference. Figures 1 to 4 The bottom of the bucket 10 includes a bottom body 11 and a baffle assembly 12.

[0034] The bottom body 11 is a shell structure, which encloses and forms a receiving space 11b. The top side of the receiving space 11b is open.

[0035] The bottom body 11 of the bucket has a mounting port 11a for mounting the impeller shaft 50. The impeller is disposed in the receiving space 11b and located above the mounting port 11a. (See reference...) Figure 6 The impeller shaft 50 is rotatably inserted into the mounting port 11a, and the top end of the impeller shaft 50 is connected to the impeller 40 to drive the impeller to rotate.

[0036] See Figure 1The mounting hole 11a penetrates the barrel bottom body 11 and is located on the bottom wall corresponding to the accommodation space 11b.

[0037] The accumulated water in the accommodation space 11b can flow out of the barrel bottom 10 through the mounting hole 11a.

[0038] The side wall corresponding to the accommodation space 11b and the bottom wall corresponding to the accommodation space 11b are transitioned by a circular arc to guide the water flow on the side wall corresponding to the accommodation space 11b to flow to the mounting hole 11a and out of the barrel bottom 10, so as to reduce the probability of the existence of accumulated water in the accommodation space 11b.

[0039] The rib assembly 12 is continuously arranged along the circumference surrounding the mounting hole 11a. The continuous arrangement means that the rib assembly 12 blocks on the radially outer side of each part of the circumference of the mounting hole 11a. The rib assembly 12 blocks the foreign matter flowing to the mounting hole 11a at each position along the circumference.

[0040] The rib assembly 12 is located on the top surface of the barrel bottom body 11. That is, the rib assembly 12 is located on the top surface of the bottom wall corresponding to the accommodation space 11b.

[0041] The rib assembly 12 defines a zigzag-extended drainage channel 12a on the top surface of the barrel bottom body 11, and the drainage channel 12a communicates the radially outer region of the rib assembly 12 and the mounting hole 11a. The water flow in the accommodation space 11b can flow into the mounting hole 11a from the radially outer side of the rib assembly 12 through the drainage channel 12a.

[0042] The barrel bottom 10 of the embodiment of the present application, because the drainage channel 12a is zigzag-extended, no through hole is formed on the rib assembly 12 which directly penetrates the radially outer region of the rib assembly 12 and the mounting hole 11a along the radial direction. Thus, the drainage requirement can be met, and the rib assembly 12 can be continuously arranged along the circumference surrounding the mounting hole 11a.

[0043] It should be noted that the foreign matter such as the button, the back-shaped needle, and the foreign nail can be deposited on the top surface of the barrel bottom 10, and under the action of the water flow, the foreign matter is easy to move to the direction close to the mounting hole 11a during the drainage. The barrel bottom 10 in the embodiment of the present application can directly block the foreign matter flowing into the mounting hole 11a along the bottom wall through the rib assembly 12 arranged on the barrel bottom body 11.

[0044] The zigzag-extended drainage channel 12a arranged in the rib assembly 12 can meet the normal drainage and avoid the accumulation of water in the barrel bottom 10.

[0045] It can be understood that the number of times of changing the extending direction of the drainage channel 12a by the bending is not limited.

[0046] In some embodiments, the installation opening 11a is arranged at the bottom of the accommodation space 11b, so that the water flow in the accommodation space 11b flows to the installation opening 11a under the action of gravity.

[0047] In some embodiments, referring to Figures 1 to 3 , the number of the water drainage channels 12a is multiple, so as to improve the efficiency of draining the water accumulated in the bottom body 11.

[0048] In some embodiments, referring to Figures 1 to 3 , the water drainage channels 12a are arranged at intervals along the circumference of the installation opening 11a, so as to facilitate the water flow around the installation opening 11a to pass through the water drainage channels 12a and enter the installation opening 11a evenly.

[0049] It can be understood that after long-term use, foreign matters are accumulated in the water drainage channels 12a, which affects the water flow passing through the water drainage channels 12a or even causes the water drainage channels 12a to be blocked. Therefore, the structure of the water drainage channels 12a needs to be convenient for cleaning.

[0050] Referring to Figure 4 , the water drainage channels 12a are provided with water flow inlets 12c and water flow outlets 12b, and the water flow enters the water drainage channels 12a from the water flow inlets 12c and exits the water drainage channels 12a from the water flow outlets 12b.

[0051] In some embodiments, referring to Figure 1 and Figure 3 , the top side of the water drainage channels 12a is open. On the one hand, when a large amount of water is drained, the water flow can flow into the water drainage channels 12a from the top side of the water drainage channels 12a, so as to improve the water drainage speed; when the water level in the bottom of the bucket is lower than the height of the rib assembly 12, the water flow can only flow into the water drainage channels 12a from the water flow inlets 12c of the water drainage channels 12a, until almost all the residual water is drained.

[0052] It can be understood that since foreign matters such as buttons, back-shaped needles, and nails can be deposited on the top surface of the bucket bottom 10, even if the water flow flows into the water drainage channels 12a from the top side of the water drainage channels 12a, some hard foreign matters cannot flow into the water drainage channels 12a from the top side of the water drainage channels 12a.

[0053] In addition, when the impeller is disassembled, the position where the foreign matters are accumulated in the water drainage channels 12a can be observed from the open position of the top side of the water drainage channels 12a, and the foreign matters accumulated in the water drainage channels 12a can be cleaned, so as to facilitate the water drainage channels 12a to be unblocked.

[0054] In some embodiments, referring to Figure 4The water inflow port 12c of the same drainage channel 12a is multiple, for example, two, three or more. The water outflow port 12b of the drainage channel 12a is one. On the one hand, the water flow in the tub bottom body 11 can enter the drainage channel 12a through more positions, reducing the probability of water accumulation in the tub bottom body 11; on the other hand, in the case of a fixed flow allowed by the drainage channel 12a, by setting multiple water inflow ports 12c, the size of the water inflow port 12c is smaller, thereby improving the blocking ability of foreign matter. The water flows from multiple water inflow ports 12c and is discharged from the same water outflow port 12b after convergence.

[0055] The specific structural form of the drainage channel 12a is not limited.

[0056] Exemplarily, referring to Figure 3 and Figure 4 , the blocking rib assembly 12 includes a plurality of first blocking ribs 121 and a plurality of second blocking ribs 122. The plurality of first blocking ribs 121 are arranged along the circumferential direction around the mounting port 11a, and adjacent two first blocking ribs 121 are spaced apart and form the water outflow port 12b of the drainage channel 12a. The second blocking rib 122 is arranged on the radially outer side of the first blocking rib 121. The first blocking rib 121 and the second blocking rib 122 can block foreign matter from flowing directly into the mounting port 11a along the radial direction of the mounting port 11a along with the water flow.

[0057] Referring to Figure 4 , the second blocking rib 122 blocks the water outflow port 12b along the circumferential direction, thereby avoiding foreign matter from directly entering the mounting port 11a through the water outflow port 12b along the radial direction of the mounting port 11a along with the water flow.

[0058] One end of the second blocking rib 122 along the length direction is spaced apart from the first blocking rib 121 to form the water inflow port 12c. On the one hand, the water flow flowing inward along the radial direction of the mounting port 11a is guided to the water inflow port 12c under the guidance of the first blocking rib 121 after being blocked by the first blocking rib 121. On the other hand, the foreign matter is blocked by the first blocking rib 121 and cannot continue to move inward along the radial direction.

[0059] It can be understood that the spacing distance between the first blocking rib 121 and the second blocking rib 122 is as small as possible on the basis of meeting the water flow, so as to reduce the probability of foreign matter entering the drainage channel 12a.

[0060] It can be understood that the first blocking rib 121 and the second blocking rib 122 are bent and extended to form a bent and extended drainage channel 12a.

[0061] In some embodiments, referring to Figure 4 , the opposite ends of the first blocking rib 121 along the length direction are folded outward along the radial direction and form the first blocking edge 1211. Adjacent two first blocking edges 1211 define the water outflow port 12b.

[0062] It can be understood that the two adjacent first blocking edges 1211 forming the water flow outlet 12b are respectively located on the two first blocking ribs 121.

[0063] Referring to Figure 4 , the water flow blocked by the second blocking rib 122 flows into the water flow inlet 12c along the circumference of the mounting hole 11a after circumventing the water flow inlet 12c. Then, the water flow is blocked by the first blocking edge 1211 and changes the flow direction to flow along the extension direction of the first blocking edge 1211 until circumventing the end of the first blocking edge 1211 away from the mounting hole 11a. Then, the water flow flows into the mounting hole 11a through the water flow outlet 12b between the two first blocking edges 1211, so that the water flow is turned multiple times by the cooperation between the first blocking edge 1211 and the second blocking rib 122, and the foreign matter can be blocked by the first blocking rib 121 and the second blocking rib 122 multiple times, thereby achieving the purpose of reducing the probability of foreign matter entering the mounting hole 11a.

[0064] In some embodiments, referring to Figure 4 , the second blocking rib 122 is folded inward along the radial direction at opposite ends along the length direction and forms a second blocking edge 1221. A part of the two adjacent first blocking edges 1211 extends into the two second blocking edges 1221 of the same second blocking rib 122.

[0065] Referring to Figure 4 , in the projection along the circumference of the mounting hole 11a, the projection of the first blocking edge 1211 and the projection of the second blocking edge 1221 coincide along the radial direction of the mounting hole 11a. On the one hand, the water flow flowing along the radial direction is blocked by the outer side of the second blocking rib 122 along the radial direction and circumvents to the position of the second blocking edge 1221, and under the blocking and guiding of the second blocking edge 1221, the water flow flows along the radial direction to the water flow inlet 12c. On the other hand, part of the water flow flowing along the circumference changes the flow direction under the blocking and guiding of the second blocking edge 1221 and flows along the radial direction to the water flow inlet 12c. The water flow flowing into the water flow inlet 12c from the circumference changes the flow direction and flows outward along the radial direction under the blocking of the first blocking edge 1221. Through the cooperation between the first blocking edge 1211 and the second blocking edge 1221, the foreign matter is prevented from directly passing through the drainage channel 12a along the radial direction gap between the first blocking edge 1211 and the second blocking edge 1221, further increasing the number of turns of the water flow, so that the foreign matter can be blocked by the first blocking edge 1211 and the second blocking edge 1221 multiple times, thereby achieving the purpose of reducing the probability of foreign matter entering the mounting hole 11a.

[0066] In some embodiments, referring to Figure 5The end of the radially inner end of the second baffle rib 1221 and the radially outer wall of the first baffle rib 121 form a water flow inlet 12c, so that the water flow in the radial direction changes the flow direction and becomes the water flow in the circumferential direction into the water flow inlet 12c, the number of water flow turning is increased, and the purpose of reducing the probability of foreign matter entering the mounting port 11a is achieved.

[0067] It can be understood that the connection position between the other parts of the first baffle rib 121 and the first baffle rib 121 is a circular arc transition structure, which reduces the force exerted by the water flow on the first baffle rib 121 when flowing through the position, and reduces the water flow noise.

[0068] It can be understood that the connection position between the other parts of the second baffle rib 122 and the second baffle rib 1221 is a circular arc transition structure, which reduces the force exerted by the water flow on the second baffle rib 122 when flowing through the position, and reduces the water flow noise.

[0069] It can be understood that the specific structural relationship between the baffle rib assembly 12 and the barrel bottom body 11 is not limited.

[0070] In some embodiments, the baffle rib assembly 12 and the barrel bottom body 11 are respectively completed after manufacturing, and are connected by bonding or clamping.

[0071] In other embodiments, the baffle rib assembly 12 and the barrel bottom body 11 are integrally formed, which can reduce the manufacturing steps of the barrel bottom 10, improve the production efficiency of the barrel bottom 10, and reduce the production cost; on the other hand, it avoids the risk of gap between the baffle rib assembly 12 and the barrel bottom body 11 after long-term use.

[0072] It can be understood that the barrel bottom 10 can be made of engineering plastic by one-time injection molding to simultaneously complete the manufacturing of the baffle rib assembly 12 and the barrel bottom body 11.

[0073] The embodiment of the present application also provides a washing barrel 30, referring to Figure 6 and Figure 5 The washing barrel 30 includes a barrel body 20 and the barrel bottom 10 of any one of the foregoing embodiments, the bottom of the barrel body 20 is connected with the top of the barrel bottom body 11, and the barrel body 20 and the barrel bottom body 11 together form a clothes processing cavity 30a. The barrel body 20 penetrates along the axial direction to communicate with the containing space 11b of the barrel bottom 10.

[0074] The clothes processing cavity 30a is used for placing clothes to be processed, and the clothes complete the cleaning work in the clothes processing cavity 30a.

[0075] It can be understood that the containing space 11b forms part of the clothes processing cavity 30a.

[0076] The top of the barrel body 20 is open to form a clothes loading and unloading opening, and the clothes enter and exit the clothes processing cavity 30a through the clothes loading and unloading opening.

[0077] The present application also provides a laundry treating apparatus, referring to Figure 6 and Figure 7 The laundry treating apparatus comprises a pulsator 40, a pulsator shaft 50, and the washing tub 30 as described in the foregoing embodiments, the top end of the pulsator shaft 50 penetrates through the mounting hole 11a and is connected with the pulsator 40, and the pulsator 40 is arranged at the bottom of the laundry treating cavity 30a.

[0078] The rotation of the pulsator shaft 50 drives the rotation of the pulsator 40. The pulsator 40 is provided with blades, and the rotation of the blades agitates the water and the laundry in the laundry treating cavity 30a, so as to rub the laundry and the water flow, thereby achieving the purpose of removing dirt.

[0079] Exemplarily, the pulsator shaft 50 is arranged along the radial direction of the mounting hole 11a and is spaced from the edge of the mounting hole 11a, so as to prevent the friction between the pulsator shaft 50 and the tub bottom body 11 during the rotation of the pulsator shaft 50, thereby reducing the probability of damage to the two.

[0080] The pulsator 40 is arranged axially and is spaced from the tub bottom 10, so as to prevent the friction between the pulsator 40 and the tub bottom 10 during the rotation of the pulsator 40.

[0081] Referring to Figure 6 , the top of the rib assembly 12 is arranged axially and is spaced from the bottom of the pulsator 40, so as to prevent the friction between the pulsator 40 and the rib assembly 12 during the rotation of the pulsator 40.

[0082] It can be understood that the size of the gap between the top of the rib assembly 12 and the bottom of the pulsator 40 is not more than the size of the rib assembly 12 along the axial direction, so as to reduce the probability of foreign matters entering the mounting hole 11a through the gap between the top of the rib assembly 12 and the bottom of the pulsator 40.

[0083] In some embodiments, in the projection along the axial direction of the washing tub 30, the projection of the rib assembly 12 is located within the projection range of the pulsator 40, thereby reducing the probability of foreign matters directly entering the mounting hole 11a from the inner side of the rib assembly 12 along the radial direction, and effectively improving the blocking effect of the rib assembly 12 on foreign matters.

[0084] Referring to Figure 1 , the gap between the bottom wall of the pulsator 40 and the corresponding bottom wall of the accommodating space 11b gradually increases in the direction along the radial direction inward. Therefore, the closer the rib assembly 12 is arranged to the edge of the mounting hole 11a along the radial direction, the more the size of the rib assembly 12 along the top-bottom direction can be increased, so as to improve the effect of blocking foreign matters. For this purpose, exemplarily, referring to Figure 7 and ​ , the rib assembly 12 is arranged at the edge of the mounting hole 11a.

[0085] In some embodiments, the laundry treating apparatus includes an outer tub 60 having an installation space therein and a drain opening communicating with the outside, a top of the installation space being open, and the washing tub 30 being disposed in the installation space. Water in the washing tub 30 can flow into the installation space through the installation opening 11a, and then be discharged out of the laundry treating apparatus through the drain opening.

[0086] The various embodiments / embodiments provided in the present application can be combined with each other without producing contradictions.

[0087] The above only describes the preferred embodiments of the present application and is not intended to limit the present application. For those skilled in the art, the present application can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
