[0042] To solve the problem that the existing barrel type washing equipment cannot determine whether the small barrel is installed in place.

[0043] Embodiment one

[0044] As Figures 1-15 shown, the present embodiment discloses a washing equipment, specifically a pulsator washing machine, which is mainly used for washing clothes, and can also be used for washing shoes and the like.

[0045] The washing equipment comprises a body 01, a large barrel 02, a first pulsator 04, a small barrel 03, a second pulsator 05, a driving mechanism 06, a water inlet box 08, a clamping block 033, a driving block 034, a second elastic member 037 and a fixing block 041.

[0046] Referring to Figure 1 , the large barrel 02 is rotatably arranged in the body 01, the first pulsator 04 is rotatably arranged in the large barrel 02 and located at the bottom of the large barrel 02, and the first pulsator 04 and the large barrel 02 are coaxially arranged.

[0047] The small barrel 03 is arranged in the large barrel 02 and coaxially arranged with the first pulsator 04 and the large barrel 02, and the small barrel 03 is installed on the first pulsator 04, so that the first pulsator 04 can drive the small barrel 03 to rotate synchronously.

[0048] The small barrel 03 and the first pulsator 04 are specifically detachably connected, and the small barrel 03 and the first pulsator 04 are quickly connected in the present embodiment. When only the large barrel 02 is needed to wash clothes and the small barrel 03 is not needed to wash clothes, the small barrel 03 can be quickly detached; when the small barrel 03 is needed to wash clothes, the small barrel 03 can be quickly installed on the first pulsator 04.

[0049] Specifically referring to Figures 2-4 , the clamping block 033 is slidably arranged at the bottom of the small barrel 03, and the first pulsator 04 is provided with a limiting groove 0411. The clamping block 033 can at least partially extend into the limiting groove 0411 to limit and fix the small barrel 03; the clamping block 033 is separated from the limiting groove 0411 to release the limiting and fixing of the small barrel 03, so as to detach the small barrel 03 from the first pulsator 04. Specifically, the clamping block 033 is moved to partially enter the limiting groove 0411 to limit and fix the small barrel 03, and the installation of the small barrel 03 is completed, which is simple and quick; the clamping block 033 is moved to separate from the limiting groove 0411 to release the limiting and fixing of the small barrel 03, so as to detach the small barrel 03, which is simple and quick. That is, the small barrel 03 of the present application is relatively simple and quick to assemble and disassemble, and has high efficiency.

[0050] More specifically, the end of the clamping block 033 can extend into the limiting groove 0411 to limit and fix the keg 03. The bottom of the keg 03 is provided with a mounting groove, the clamping block 033 is slidingly arranged in the mounting groove, the mounting groove is arranged towards the outside of the keg 03, and the extension line of the length direction of the mounting groove can extend to the center axis of the keg 03. The second elastic member 037 is arranged in the mounting groove, and the two ends of the second elastic member 037 act on the groove bottom of the mounting groove and the clamping block 033 respectively. The second elastic member 037 can drive the clamping block 033 to partially extend into the limiting groove 0411. The second elastic member 037 is specifically a compression spring, a connecting column 0332 is arranged at the end of the clamping block 033, the spring is sleeved on the connecting column 0332, and the connecting column 0332 limits the spring to ensure the stability of the spring, so that the spring can effectively drive the clamping block 033 to slide to partially extend into the limiting groove 0411. Under the action of the second elastic member 037, the end of the clamping block 033 away from the second elastic member 037 can always extend into the limiting groove 0411. In other embodiments, the second elastic member 037 can also be a rubber spring or an air spring, as long as it can drive the end of the clamping block 033 to extend into the limiting groove 0411.

[0051] The accommodating groove 0331 is arranged on the clamping block 033 and is arranged at the middle part of the clamping block 033, and the driving block 034 is arranged in the accommodating groove 0331. The upward first inclined surface 0341 is arranged on the driving block 034, the downward second inclined surface 0333 is arranged on the clamping block 033, the second inclined surface 0333 is located at the end close to the second elastic member 037, that is, the end away from the limiting groove 0411, and the first inclined surface 0341 and the second inclined surface 0333 are in close contact. When the driving block 034 moves upward, the first inclined surface 0341 moves upward and slides relative to the second inclined surface 0333, which drives the clamping block 033 to move away from the limiting groove 0411, so that the clamping block 033 is separated from the limiting groove 0411.

[0052] The accommodating hole 038 is arranged on the side wall of the keg 03, the connecting rod 035 is connected with the driving block 034, and the connecting rod 035 extends upward out of the keg 03 through the accommodating hole 038. Pulling the connecting rod 035 upward can drive the driving block 034 to move upward, so as to drive the clamping block 033 to separate from the limiting groove 0411. After the connecting rod 035 is pressed downward, the clamping block 033 is no longer limited, and under the action of the second elastic member 037, the clamping block 033 can be driven to move towards one end of the limiting groove 0411, so that the clamping block 033 partially extends into the limiting groove 0411.

[0053] Preferably, the present embodiment has two symmetrical connection positions between the bucket 03 and the first pulsator 04, i.e. two sets of the clamping block 033, the second elastic member 037 and the fixing block 041. In other embodiments, one skilled in the art can select multiple connection positions according to the connection needs, and the multiple connection positions are arranged along the circumference of the bucket 03.

[0054] Referring to Figure 5 and 6 , the washing device further comprises a handle 036 pivotally connected to the top of the bucket 03, and the handle 036 is connected to the top of the connecting rod 035. Pulling the handle 036 upwards can drive the connecting rod 035 to move upwards. Specifically, the handle 036 is provided with a connecting pin 0361 located above the pivot connection between the bucket 03 and the handle 036. When the handle 036 is pulled upwards, the connecting pin 0361 can move in an arc. The top of the connecting rod 035 is provided with a strip-shaped hole 0351 in the horizontal direction, and the connecting pin 0361 is arranged in the strip-shaped hole 0351. Pulling the handle 036 upwards drives the connecting pin 0361 to move in an arc and horizontally relative to the strip-shaped hole 0351, thereby driving the connecting rod 035 to move vertically upwards, and driving the driving block 034 to move upwards to drive the clamping block 033 to disengage from the limiting groove 0411. The strip-shaped hole 0351 can ensure that the connecting rod 035 always moves vertically and does not tilt, thereby ensuring the stability of the connection between the connecting rod 035 and the driving block 034 and preventing damage to the connection between the connecting rod 035 and the driving block 034.

[0055] Please refer to Figures 2-5 , the fixing block 041 is fixed on the first pulsator 04, and the two are specifically fixed by screws. The limiting groove 0411 is arranged on the fixing block 041. In order to facilitate installation, the bottom of the end of the clamping block 033 close to the fixing block 041 is an inclined surface, and the edge of the upper part of the fixing block 041 is also chamfered, so that the clamping block 033 can be better compressed and installed.

[0056] Referring to Figures 7-9 , the arrow in Figure 8 indicates the water flow path in the bucket 03. The side wall of the bucket 03 is provided with a drainage channel 032 along the length direction thereof. The water inlet of the drainage channel 032 is located at the top of the inner wall of the bucket 03. The bottom of the first pulsator 04 is provided with a drainage hole 042, and the drainage channel 032 is communicated with the drainage hole 042. When the bucket 03 rotates, the water in the bucket 03 flows into the drainage channel 032, and then is discharged through the drainage hole 042 to the bottom of the first pulsator 04, and then is discharged through the drain pipe below the machine body 01, as shown in Figure 8As indicated by the arrow. During the drainage process, the water will not flow into the large bucket 02, ensuring that the water discharged from the small bucket 03 will not splash onto the clothes in the large bucket 02, and will not wet or contaminate the large bucket 02 or the clothes inside it.

[0057] The small bucket 03 is a conical cylinder, with the inner diameter of the top end being larger than that of the bottom end. This conical design allows the water inside the bucket 03 to be thrown to the top at a relatively low rotational speed, thus entering the drainage channel 032; this prevents clothes inside the bucket 03 from being easily thrown out.

[0058] Specifically, in this embodiment, the drainage channel 032 protrudes both inward and outward on the side wall of the small bucket 03. The drainage channel 032 is vertically arranged and is a pipe of uniform diameter, resulting in the outward protrusion increasing towards the bottom, with almost no outward protrusion at the very top; conversely, the inward protrusion increases towards the top, with the top almost entirely protruding inward and the bottom almost not protruding inward. The drainage channel 032 and the small bucket 03 are integrally formed, ensuring the structural strength of both. In other embodiments, the drainage channel 032 may also protrude inward only on the inner wall of the small bucket 03, or only outward only on the outer wall of the small bucket 03.

[0059] The drain hole 042 is located directly below the drain channel 032. A drain hole 042 with a larger diameter is provided directly below the drain channel 032, which allows the water in the drain channel 032 to be quickly drained to the bottom of the first impeller 04 and then discharged through the drain pipe under the body 01. In other embodiments, multiple drain holes 042 with smaller diameters can also be provided below the drain channel 032. This arrangement results in a slightly slower drainage speed, but it can effectively ensure the structural strength of the first impeller 04.

[0060] The first impeller 04 is equipped with a connector, and the drainage channel 032 is inserted into the connector. Specifically, as shown... Figures 7-9 As shown, a raised rib 043 is provided around the drain hole 042 of the first impeller 04, and the raised rib 043 surrounds to form an insertion interface. The bottom of the drain channel 032 located inside the small bucket 03 is provided with a groove; after the small bucket 03 is installed, the part of the raised rib 043 located outside the small bucket 03 is exposed, and the part located inside the small bucket 03 is embedded in the groove.

[0061] Regarding the setting of the drain hole 042, it should be noted that its placement below the drain channel 032 is not a limitation of the present invention. Without departing from the principles of the present invention, those skilled in the art can employ other configurations in other embodiments, as long as they can communicate with the drain channel 032 and drain the water within the drain channel 032 to the bottom of the first impeller 04. For example, the first impeller 04 may have a water-dispelling rib with a drain cavity arranged horizontally. The drain hole 042 is located on the bottom wall of the drain cavity, and a connecting opening is provided on the outer wall of the small bucket 03, allowing the drain channel 032 to communicate with the drain cavity. Water in the drain channel 032 can flow into the drain cavity, then through the drain cavity to the drain hole 042, and finally drain below the first impeller 04. It is then discharged through the drain pipe below the body 01. All of these configurations do not depart from the basic principles of the present invention and therefore fall within the protection scope of the present invention.

[0062] Specific reference Figure 7 Two drainage channels 032 are symmetrically arranged along the circumference on the side wall of the small bucket 03. This ensures that the water in the small bucket 03 can be drained quickly without the need for more drainage channels 032, making the overall structure simpler and saving on manufacturing difficulty and cost.

[0063] Regarding the number of drainage channels 032, it should be noted that providing two is not a limitation of the present invention. Without departing from the principles of the present invention, the number of drainage channels can be greater. Specifically, multiple drainage channels 032 are spaced circumferentially along the side wall of the small bucket 03. Specifically, there can be three, four, or five, etc. These all do not depart from the basic principles of the present invention and therefore all fall within the protection scope of the present invention.

[0064] Continue to refer to Figure 1 , 10In section 11, the second impeller 05 is disposed inside the small tub 03 and located at the bottom of the small tub 03, with the second impeller 05 and the small tub 03 coaxially arranged. The washing device also includes a second transmission assembly 07, through which the second impeller 05 is rotatably connected to the small tub 03. Specifically, the second transmission assembly 07 includes a bearing housing 071, a bearing 072, an end cap 073, a connecting shaft 074, and a water seal 075. The bearing 072 is sleeved on the connecting shaft 074, with its inner ring interference-fitted with the connecting shaft 074. The bearing 072 is embedded in the bearing housing 071, and the end cap 073 is fixed to the bearing housing 071 and abuts against the outer ring of the bearing 072. The outer ring of the bearing 072 can be fixed inside the bearing housing 071 through the cooperation of the end cap 073 and the bearing housing 071. Two water seals 075 are sleeved on the connecting shaft 074; the water seals 075 are specifically the water seals 075 commonly used in the washing machine industry. Two water seals 075 are located on either side of the bearing 072. One water seal 075 is embedded in the bearing housing 071, and the other water seal 075 is embedded in the end cap 073. The two water seals 075 work together to seal the bearing 072 within the bearing housing 071, preventing water from the small bucket 03 from flowing into the bearing 072 and ensuring that the bearing 072 will not rust. A sealing ring is provided between the outer circumference of the end cap 073 and the inner wall of the bearing housing 071. The sealing ring is partially embedded in the end cap 073, ensuring a tight seal between the end cap 073 and the bearing housing 071. The bearing housing 071 is fixed to the small bucket 03, and the two are specifically connected by screws. A groove is provided around the end face of the bearing housing 071, and the sealing ring is embedded in the groove. The sealing ring is clamped between the bearing housing 071 and the bottom of the small bucket 03, sealing the bearing housing 071 and the bottom of the small bucket 03, preventing water from flowing out of the small bucket 03.

[0065] The second impeller 05 is fixed to the connecting shaft 074. Specifically, the second impeller 05 has a polygonal hole, and the top of the connecting shaft 074 is also a polygonal shaft, corresponding to the polygonal hole. The top of the connecting shaft 074 extends into the polygonal hole, allowing the connecting shaft 074 to drive the second impeller 05 to rotate. A threaded hole is provided at the top of the connecting shaft 074, and a screw is used to axially limit the second impeller 05, preventing it from falling off.

[0066] Through the connection of the second transmission assembly 07, the second impeller 05 can rotate relative to the small tub 03, and the rotation direction can be either the same or opposite. This ensures that the second impeller 05 and the small tub 03 rotate simultaneously in opposite directions, thereby ensuring effective washing of the clothes in the small tub 03. Specifically, the first impeller 04 is a large impeller, and the second impeller 05 is a small impeller. The rotation of the first impeller 04 can wash the clothes in the large tub 02, and the rotation of the second impeller 05 can wash the clothes in the small tub 03.

[0067] like Figure 1 and 10As shown, the large barrel 02, the first impeller 04, and the second impeller 05 are driven to rotate by a drive mechanism 06. The drive mechanism 06 is located inside the machine body 01, at the bottom of the first impeller 04. The large barrel 02, the first impeller 04, and the second impeller 05 are all connected to the drive mechanism 06. The drive mechanism 06 includes a drive motor and a clutch located at the output end of the drive motor. The large barrel 02, the first impeller 04, and the second impeller 05 are respectively connected to different output ends of the clutch, so that the drive motor can simultaneously or separately drive the large barrel 02, the first impeller 04, and the second impeller 05 to rotate. This allows the drive mechanism 06 to simultaneously control the rotation of the large barrel 02, the first impeller 04, and the second impeller 05, or to individually control the operation of one or two of them. Specifically, the clutch is equipped with a first output shaft 061, a second output shaft 062, and a third output shaft 063. The second output shaft 062 is sleeved on the first output shaft 061 and is rotatable relative to the first output shaft 061; the third output shaft 063 is sleeved on the second output shaft 062 and is rotatable relative to the second output shaft 062. The second output shaft 062 is fixedly connected to the first impeller 04, so that the drive mechanism 06 can drive the first impeller 04 to rotate via the second output shaft 062; the third output shaft 063 is fixedly connected to the large barrel 02, so that the drive mechanism 06 can drive the large barrel 02 to rotate via the third output shaft 063.

[0068] Specific reference Figure 10 , 12 In section 13, the first output shaft 061 is driven by the second pulsator 05, so that the drive mechanism 06 can drive the second pulsator 05 to rotate via the first output shaft 061. Specifically, the washing device also includes a connecting assembly 07. When the tub 03 is installed in place, the drive mechanism 06 is driven by the connecting assembly 07 to rotate the second pulsator 05. When the tub 03 is not installed in place, the connecting assembly 07 can drive the second pulsator 05 and the tub 03 to pop upwards, and disconnect the drive mechanism 06 from the second pulsator 05. The upward popping of the second pulsator 05 and the tub 03 can indicate to the user that the tub 03 is not installed in place, allowing the user to adjust it. Disconnecting the drive mechanism 06 from the second pulsator 05 prevents the drive mechanism 06 from driving the second pulsator 05 to rotate, ensuring that the tub 03 will not fall off due to rotation and avoiding the danger caused by the tub 03 falling off.

[0069] Specifically, the connecting assembly 07 includes a first connecting member 091, a second connecting member 092, and a first elastic member 093. The first connecting member 091 is fixedly connected to the first output shaft 061. The first elastic member 093 can be a compression spring, a pneumatic spring, or a rubber spring, etc. In this embodiment, a compression spring is preferred because it has a larger compression stroke and is better suited for the connecting assembly 07.

[0070] The second connector 092 is slidably connected to the first connector 091 in a vertical manner, and the first elastic member 093 can drive the second connector 092 to move upward.

[0071] The first connecting member 091 is cylindrical, with an annular stop protruding inward at its top to prevent the second connecting member 092 from detaching from the first connecting member 091. The second connecting member 092 is also cylindrical, with its top closed. The first connecting member 091 is fitted onto the second connecting member 092. A first transmission tooth 0911 is located at the bottom inner side of the first connecting member 091, and a second transmission tooth is located at the bottom outer side of the second connecting member 092. A first elastic member 093 is located inside the second connecting member 092, and its two ends act on the first output shaft 061 and the second connecting member 092 of the drive mechanism 06, specifically, its top end acts on the second connecting member 092, and its bottom end acts on the first output shaft 061. In other embodiments, the first elastic member 093 can also be located between the first connecting member 091 and the second connecting member 092, with its two ends acting on the first connecting member 091 and the second connecting member 092, specifically, its bottom end acts on the first connecting member 091, and its top end acts on the second connecting member 092.

[0072] Although the first connector 091 is sleeved on the second connector 092 in this embodiment, this is not a limitation of the present invention. Without departing from the principle of the present invention, in other embodiments, the second connector 092 is sleeved on the first connector 091, the first transmission tooth 0911 is located at the bottom end of the outer side of the first connector 091, and the second transmission tooth is located at the bottom end of the inner side of the second connector 092; the top end of the second connector 092 is sealed and can be connected to the connecting shaft 074.

[0073] The first elastic element 093 is located between the second connecting element 092 and the first connecting element 091, and its two ends act on the first connecting element 091 and the second connecting element 092 respectively. Specifically, it acts on the top of the first transmission gear 0911 and the top wall of the inner cavity of the second connecting element 092. Alternatively, the first elastic element 093 is located outside the second connecting element 092, and its two ends act on the first output shaft 061 and the second connecting element 092 respectively. Specifically, its bottom end acts on the first output shaft 061, and its top end acts on the second connecting element 092 (in order to make the first elastic element 093 have an abutment position, a protrusion can be provided on the outer wall of the second connecting element 092 so that the top end of the first elastic element 093 abuts against the protrusion).

[0074] The washing equipment also includes a first transmission assembly, which includes a first transmission gear 0911 disc and a second transmission gear disc capable of meshing. The first transmission gear 0911 disc is connected to the second impeller 05, specifically to the bottom end of the connecting shaft 074. The second transmission gear disc is connected to the output end of the drive mechanism 06, specifically to the first output shaft 061.

[0075] When the small bucket 03 is installed in place, the first transmission gear 0911 meshes with the second transmission gear, enabling the drive mechanism 06 to drive the second impeller 05 to rotate. When the small bucket 03 is not installed in place, the second impeller 05 and the small bucket 03 pop upwards, causing the first transmission gear 0911 to disengage from the second transmission gear, thus preventing the drive mechanism 06 from driving the second impeller 05 to rotate.

[0076] More specifically, both the first transmission gear 0911 disc and the second transmission gear disc are conical gear discs. The inner surface of the first transmission gear 0911 disc is provided with transmission teeth, and the outer surface of the second transmission gear disc is provided with transmission teeth. The first transmission gear 0911 disc can cover the second transmission gear disc.

[0077] The second transmission gear has a through hole in the middle, and the second connector 092 passes through the through hole and can slide up and down relative to the second transmission gear. The upward movement of the second connector 092 can push the first transmission gear 0911 to move upward, thereby driving the small bucket 03 and the second impeller 05 to pop up.

[0078] Specifically, when the small bucket 03 is installed in place, the small bucket 03 will not move upward due to the limiting of the snap-fit ​​block 033 and the limiting groove 0411. Under the squeezing force of the small bucket 03, the second connecting piece 092 moves downward, so that it is entirely located inside the first connecting piece 091 except for the top part; and the first transmission gear 0911 wheel and the second transmission gear can mesh with each other, so that the drive mechanism 06 can drive the second impeller 05 to rotate.

[0079] When the small bucket 03 is not properly installed, the locking block 033 and the limiting groove 0411 are not properly engaged, preventing the small bucket 03 from being locked. The first elastic element 093 can drive the second connecting element 092 to move upwards. The second connecting element 092 can push the second impeller 05 and the small bucket 03 upwards, causing the second impeller 05 and the small bucket 03 to pop upwards. This disengages the first transmission gear 0911 from the second transmission gear, preventing the drive mechanism 06 from driving the second impeller 05 to rotate.

[0080] The space between the large tub 02 and the small tub 03 is the first washing chamber 021, and the space inside the small tub 03 is the second washing chamber 031. Since the large tub 02, the first impeller 04, and the second impeller 05 can rotate in different directions, and their rotation can be controlled independently or not; therefore, the first washing chamber 021 and the second washing chamber 031 can be used simultaneously, or only one of them can be used. When there are few clothes, only the second washing chamber 031 can be used for washing; when there are slightly more clothes, only the first washing chamber 021 can be used; when there are many clothes, both the first washing chamber 021 and the second washing chamber 031 can be used simultaneously. Of course, the first washing chamber 021 and the second washing chamber 031 can also be used to wash different types of clothing. For example, the first washing chamber 021 can be used to wash regular outerwear, and the second washing chamber 031 can be used to wash underwear; or the first washing chamber 021 can be used to wash regular clothing, and the second washing chamber 031 can be used to wash socks, etc.

[0081] like Figure 1 , 14 As shown in Figure 15, the water inlet box 08 is located inside the body 01 and above the large tub 02. The water inlet box 08 is provided with a water outlet 0811, which is specifically the water outlet 0811 of the box cavity 081. Water can be injected into the first washing chamber 021 through the water outlet 0811, specifically in a waterfall manner.

[0082] The water inlet box 08 is also provided with a water outlet 082, through which water can be injected into the second washing chamber 031.

[0083] Water is injected into the first washing chamber 021 and the second washing chamber 031 through the water outlet 0811 and the water outlet hole 082 respectively, which can ensure that water is injected into the small bucket 03 and the large bucket 02 respectively. Moreover, the water inlet box 08 has a simple structure and low cost.

[0084] The drain hole diameter of the water outlet 082 is smaller than the inner diameter of the water outlet 082. Because the drain hole diameter of the water outlet 0811 is smaller, the water outlet 082 can spray water into the small bucket 03 in the shape of a water column. Even when the water flow is small, it can ensure that the water in the water outlet 082 flows into the small bucket 03.

[0085] Preferably, in this embodiment, the water outlet 082 includes a water flow section 0821, a transition section 0822, and a drainage section 0823 connected in sequence. The inner diameter of the water flow section 0821 is larger than the inner diameter of the drainage section 0823. The water flow section 0821 and the drainage section 0823 are smoothly connected through the transition section 0822. The drain outlet is located at the end of the drainage section 0823 away from the transition section 0822, allowing water in the water outlet 082 to be sprayed out through the drainage section 0823. The smaller diameter of the drainage section 0823 ensures that the drain outlet sprays water into the small bucket 03 in a jet shape, ensuring that even with a small water flow, water from the water outlet 082 is injected into the small bucket 03.

[0086] Regarding the water outlet 082, it should be noted that although the rotation in this embodiment is a segmented design, this is not a limitation of the present invention. Without departing from the principle of the present invention, the water outlet 082 can also be designed in other ways. For example, the end of the water outlet 082 near the drain outlet is a conical hole, which is the drain section 0823, and the end with the smaller diameter of the conical hole is the drain outlet. This does not depart from the basic principle of the present invention, and therefore will fall within the protection scope of the present invention.

[0087] The drainage section 0823 is oriented towards the small bucket 03 and is tilted downwards, so that the drainage outlet can spray water into the small bucket 03 to fill the small bucket 03 with water.

[0088] A water outlet pipe 083 is provided at the bottom of the water inlet box 08, and a drainage section 0823 is provided on the water outlet pipe 083. The water outlet pipe 083 is fixedly connected to the bottom wall of the water inlet box 08 by a reinforcing rib. The other parts of the water outlet 082 are provided on the side wall of the water inlet box 08. Specifically, protrusions are provided on the rear side wall and bottom wall of the water inlet box 08, and the water flow section 0821 and transition section 0822 of the water outlet 082 are located within the protrusions. The water inlet box 08, the protrusions, the water outlet pipe 083 and the reinforcing rib are integrally formed, which ensures the structural strength of the water inlet box 08.

[0089] Regarding the water outlet pipe 083, it should be noted that although water outlet pipe 083 is selected in this embodiment, this is not a limitation of the present invention. Without departing from the principle of the present invention, the drainage section 0823 can also adopt other configuration forms, as long as it faces the small bucket 03 and is inclined downwards. For example, the bottom of the water inlet box 08 is provided with a protrusion, and the drainage section 0823 is located inside the protrusion, with the protrusion facing the small bucket 03 and inclined downwards.

[0090] The water inlet box 08 is also equipped with a water inlet, which can supply water to the box cavity 081 and the water outlet 082 of the water inlet box 08. Specifically, a control valve assembly is provided on the water inlet, which is used to control the water inlet to supply water to both the box cavity 081 and the water outlet 082 simultaneously, and can also control the water inlet to supply water to either the box cavity 081 or the water outlet 082. Specifically, the control valve assembly includes two control valves, and a three-way channel in the form of a three-way pipe is set at the water inlet, wherein the first channel is for water inlet; the second channel can inject water into the water inlet box 08, and a control valve is provided on the second channel, which can determine whether to inject water into the box cavity 081 of the water inlet box 08 by controlling the control valve; a control valve is provided on the third channel, which can determine whether to inject water into the water outlet 082 by controlling the control valve. By controlling the opening and closing of two control valves, it is possible to control the simultaneous supply of water to the box cavity 081 and the water outlet 082, or to control the supply of water to either the box cavity 081 or the water outlet 082.

[0091] Example 2

[0092] like Figure 16 and 17 As shown, this embodiment discloses a washing device, which has a structure basically the same as the washing device in Embodiment 1, except that the transmission method between the drive mechanism 06 and the second impeller 05 is different. In this embodiment, the first output shaft 061 of the drive mechanism 06 is fixedly connected to the first connecting member 091. When the small tub 03 is installed inside the large tub 02, the second impeller 05 is connected to the second connecting member 092, specifically connected to the connecting shaft 074. The second connecting member 092 and the connecting shaft 074 are connected by a spline, or the bottom end of the connecting shaft 074 is set in a polygonal shape, and the top end of the second connecting member 092 is provided with a polygonal hole.

[0093] The bottom of the first connecting member 091 is provided with a first transmission tooth 0911, and the bottom of the second connecting member 092 is provided with a second transmission tooth. When the small bucket 03 is installed in place, the first impeller 04 can lock the small bucket 03 (specifically through the snap-fit ​​block 033 and the limiting groove 0411). Under the pressure of the second impeller 05, the second connecting member 092 can overcome the resistance of the first elastic member 093 and move downward, so that the second connecting member 092 is located at the bottom, and the first transmission tooth 0911 and the second transmission tooth can mesh, so that the drive mechanism 06 can drive the second impeller 05 to rotate through the connecting assembly 07.

[0094] When the small bucket 03 is not properly installed, the first impeller 04 cannot lock the small bucket 03. The first elastic element 093 can drive the second connecting element 092 to move upward, thereby causing the second impeller 05 and the small bucket 03 to pop upward. The upward movement of the second connecting element 092 will cause the second transmission tooth to be above the first transmission tooth 0911, and the two cannot mesh, so that the connecting assembly 07 disconnects the transmission connection between the drive mechanism 06 and the second impeller 05; thus, the drive mechanism 06 cannot drive the second impeller 05 to rotate.

[0095] The first transmission tooth 0911 has a first guide portion 0912 at its top, and the second transmission tooth has a second guide portion at its bottom. The first guide portion 0912 and the second guide portion cooperate to enable the first transmission tooth 0911 and the second transmission tooth to mesh. Specifically, the top of the first transmission tooth 0911 is pointed and / or arc-shaped, and the bottom of the second transmission tooth is pointed and / or arc-shaped. Preferably, the top of the first transmission tooth 0911 is an isosceles triangle, and the uppermost part is arc-shaped; the bottom of the second transmission tooth is an isosceles triangle, and the lowermost part is arc-shaped. During the installation of the small bucket 03, under downward low pressure, the second transmission tooth can smoothly mesh with the first transmission tooth 0911 through the cooperation of the first guide portion 0912 and the second guide portion, avoiding the phenomenon that the top of the first transmission tooth 0911 abuts against the bottom of the second transmission tooth, which would prevent normal installation.

[0096] The technical solution of the present invention has been described above with reference to the preferred embodiments shown in the accompanying drawings. However, it will be readily understood by those skilled in the art that the scope of protection of the present invention is obviously not limited to these specific embodiments. Without departing from the principles of the present invention, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after such changes or substitutions will all fall within the scope of protection of the present invention.
