Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of clothes processing equipment, and particularly provides a laundry equipment. BACKGROUND

[0002] The existing small washing machine is mainly used for washing a small number of clothes or socks, scarves and other small items to be washed. The internal structure is basically the same as that of a conventional washing machine, and the size of the whole machine is mainly reduced by reducing the capacity of the washing drum. However, due to the requirement of containing a certain amount of washing water and items to be washed, the size of the washing drum cannot be greatly reduced, so the floor space occupied by the small washing machine cannot be significantly reduced. Moreover, the weight reduction design of the small washing machine mainly reflects in the reduction of the size of the drum, and the heavy components such as the water inlet pump and the water inlet pipeline still need to be arranged inside the equipment to meet the requirements of washing and rinsing water, so the weight of the whole machine cannot be greatly reduced compared with the conventional washing machine.

[0003] Therefore, there is a need for a new laundry equipment to solve the above problems. SUMMARY

[0004] The present application aims to solve the above technical problems, i.e., to solve the problems of complex structure, difficulty in greatly reducing the weight and size of the machine body by reducing the capacity of the washing drum. The present application provides a laundry equipment, which comprises a washing drum, a water storage member, a washing assembly and a driving device. The washing assembly comprises a rotating shaft arranged in the washing drum and a squeezing cover. The rotating shaft comprises a shaft sleeve and an Archimedes spiral shaft fixed in the shaft sleeve. The Archimedes spiral shaft can form a spiral bore in the shaft sleeve. The shaft sleeve is arranged vertically. The driving device is arranged to drive the shaft sleeve to rotate. The bottom of the washing drum is provided with a mounting hole. The bottom of the shaft sleeve extends to the outside through the mounting hole and is inserted into the water storage member. The outer side of the shaft sleeve is provided with an external thread structure. The middle part of the squeezing cover is provided with an internal thread structure matched with the external thread structure. The inner side wall of the washing drum is provided with a limiting rib arranged vertically to limit the rotation of the squeezing cover. The squeezing cover is provided with a clamping groove matched with the limiting rib. In the water inlet working condition, the driving device drives the shaft sleeve to rotate, so that the water in the water storage member is conveyed upward through the spiral bore to enter the washing drum. The squeezing cover is lifted upward by the internal thread structure and stays at the top end of the shaft sleeve by the external thread structure. In the washing working condition, the driving device drives the shaft sleeve to rotate forward and backward reciprocatingly. The squeezing cover moves up and down along the external thread structure by the internal thread structure, so as to repeatedly squeeze the items to be washed.

[0005] In the technical scheme, the laundry equipment can not only drive the pressing cover to repeatedly press the laundry at the bottom of the washing tub through the forward and reverse reciprocating rotation of the rotating shaft, but also guide the washing water in the water storage member into the washing tub through the spiral hole in the rotating shaft, so that the washing assembly and the water inlet assembly of the laundry equipment are combined, the water inlet components such as the water inlet pump and the water inlet pipeline which are heavy and occupy a large area are not needed to be separately arranged, the internal structure of the laundry equipment is simplified, the lightweight design effect of the laundry equipment is achieved to some extent, and the laundry equipment is especially suitable for being arranged as a small washing machine, so that the weight and the size of the small washing machine are further reduced by reducing the water inlet components while ensuring the normal water inlet washing of the small washing machine.

[0010] In the preferred technical scheme of the laundry equipment, the height of the blades of the impeller gradually decreases from the center to the edge.

[0011] In the above technical solution, the stirring capacity of the impeller gradually increases from the edge to the center, so that the strong stirring effect at the center prevents the clothes from staying near the shaft sleeve, and the clothes are dispersed in the barrel, thereby preventing the clothes from being wound on the shaft sleeve and affecting the downward movement of the squeezing cover or reducing the washing effect.

[0013] In the above technical solution, the washing machine of the present application can trigger the siphon effect and realize automatic drainage through the siphon pipe by continuing to rotate the water inlet through the shaft sleeve when drainage is needed, without setting a drainage pump, further simplifying the internal structure of the washing machine, making the overall size and weight of the washing machine set as a small washing machine more reducible, and the lightweight and small volume design more effective.

[0018] In the preferred technical scheme of the laundry equipment, the top of the installation bin is provided with a first installation groove, the water inlet port of the water guide structure is formed in the first installation groove, the top side of the sewage storage member is provided with a containing hole for containing the water storage member, the top of the sewage storage member is provided with a second installation groove, the second installation groove is provided with a water inlet port in communication with the inner cavity of the sewage storage member, in the installed case, the bottom of the washing drum is clamped in the first installation groove, the water outlet end of the siphon pipe is aligned and communicated to the water inlet port, the bottom of the installation bin is clamped in the second installation groove, and the water outlet end of the water guide structure is aligned and communicated to the water inlet port.

[0019] In the preferred technical scheme of the laundry equipment, the laundry equipment further comprises a control module and at least one water level sensor, the control module is connected with the water level sensor and the driving device respectively, each water inlet water level corresponds to one water level sensor, so that the control module can control the driving device to adjust the water inlet rotating speed of the shaft sleeve to the non-water inlet rotating speed when the water level sensor detects that the washing water is filled to the sensing water level.

In addition, the terms "first", "second" are only for the purpose of description, and cannot be understood as indicating or implying relative importance.

[0031] In addition, it also needs to be explained that, in the description of the present application, unless otherwise explicitly specified and limited, the terms "mounting", "connecting", "connecting" should be understood broadly, for example, it can be fixed connection, or detachable connection, or integral connection; it can be directly connected, or indirectly connected through intermediate medium; it can be the communication inside two elements. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0032] As Figures 1-3The laundry equipment of the present application comprises a shell (not shown in the figure) and a washing tub 1, a water storage member 7, a washing assembly 2 and a driving device 3 arranged in the shell. The washing tub 1 is arranged vertically, the tub body of the washing tub 1 is closed so that the inner space of the washing tub 1 can hold washing water and laundry, and the position of the tub opening of the washing tub 1 is provided with a feeding opening and an outer cover capable of closing / opening the feeding opening. The washing assembly 2 comprises a rotating shaft and a pressing cover 22 arranged in the washing tub 1. The rotating shaft specifically comprises a shaft sleeve 21 and an Archimedes spiral shaft 212 fixed in the shaft sleeve 21, the Archimedes spiral shaft 212 comprises a shaft center coaxially arranged with the shaft sleeve 21 and a spiral structure arranged on the shaft center, the spiral structure has the same spiral shape as the Archimedes spiral line, at least a part of the outer side end of the spiral structure (i.e. the end of the spiral structure away from the shaft center) is fixedly connected with the inner wall of the shaft sleeve 21, so that a spiral-shaped water lifting hole diameter can be formed in the shaft sleeve 21 in the axial direction. The bottom of the washing tub 1 is provided with a mounting hole 12, at least a part of the water storage member 7 is arranged below the bottom of the washing tub 1, the shaft sleeve 21 is vertically arranged in the washing tub 1 in a rotating manner, the bottom of the shaft sleeve 21 extends to the outside of the bottom through the mounting hole 12, and the bottom of the shaft sleeve 21 is inserted into the water storage cavity of the water storage member 7, so that the bottom end of the spiral hole diameter communicates with the water storage cavity. The driving device 3 is arranged on the outer bottom or inner bottom of the washing tub 1, and the driving device 3 is connected with the shaft sleeve 21 to output driving torque to the shaft sleeve 21 and drive the shaft sleeve 21 to rotate in forward and reverse directions. The outer side of the shaft sleeve 21 is provided with an outer thread structure 211, the middle part of the pressing cover 22 is provided with an inner thread structure 221 matched with the outer thread structure 211, and the pressing cover 22 is sleeved on the shaft sleeve 21 through the inner thread structure 221 and can be matched with the outer thread structure 211 on the shaft sleeve 21. At the same time, the inner side wall of the washing tub 1 is provided with a limiting rib 11 capable of limiting the rotation of the pressing cover 22 in the vertical direction, the edge of the pressing cover 22 is provided with a clamping groove 222 matched with the limiting rib 11, and in the installed state, the limiting rib 11 is clamped in the clamping groove 222, so that when the shaft sleeve 21 rotates, the limiting groove can limit the pressing cover 22 from rotating with the outer thread structure 211 on the shaft sleeve 21, thereby promoting the pressing cover 22 to be pushed up and down by the rotating outer thread structure 211 and move up and down along the shaft sleeve 21.

[0033] Through the above setting, in the water inlet working condition, the driving device 3 drives the shaft sleeve 21 to drive the Archimedes screw shaft 212 to rotate in the same direction at high speed all the time, the water in the water storage member 7 is rolled into the spiral hole diameter on the Archimedes screw shaft 212 and climbs upward along with the rapid rotation of the Archimedes screw shaft 212, so as to enter the washing barrel 1 along the spiral hole diameter in the shaft sleeve 21, and in the rotation process of the shaft sleeve 21, the extrusion cover 22 is lifted upward by the inner thread structure 221 through the outer thread structure 211, the rotating outer thread structure 211 promotes the extrusion cover 22 to remain on the top of the shaft sleeve 21, until the water inlet amount in the washing barrel 1 reaches the expected water amount. The rotation speed of the shaft sleeve 21 in the water inlet process is set to allow the Archimedes screw shaft 212 to roll the washing water in the water storage cavity into the spiral hole diameter and into the washing barrel 1.

[0034] In the washing working condition, the driving device 3 drives the shaft sleeve 21 to rotate forward and backward reciprocatingly, and the extrusion cover 22 moves up and down along the outer thread structure 211 through the inner thread structure 221, so as to repeatedly extrude the washing object. In this process, the rotation speed of the shaft sleeve 21 is lower than that in the water inlet process, and the rotation direction of the shaft sleeve 21 changes according to the moving position of the extrusion cover 22, reverses when the extrusion cover 22 is extruded downward to the limit position or the set position, and reverses when the extrusion cover 22 moves upward to the top of the outer thread structure 211, so as to make the extrusion cover 22 always move up and down, extrude or press the washing object along the outer thread structure 211, and clean the washing object by extrusion or rinsing. The rotation speed of the shaft sleeve 21 in the washing process is set to meet the extrusion or pressing of the washing object by the extrusion cover 22, and not to guide the washing water in the water storage cavity into the washing barrel 1 (that is, the water is not rolled into the spiral hole diameter or the water rolled into the spiral hole diameter is not enough to be delivered to the top of the shaft sleeve 21) when the shaft sleeve 21 rotates.

[0035] In addition to the above washing working condition, the above washing assembly can also dehydrate the washing object. Specifically, in the dehydration working condition, the extrusion cover 22 can be kept in the state of tightly extruding the washing object for a preset time, and the above extrusion action is repeated for multiple times in the dehydration process, until most of the washing water soaked on the washing object is extruded out, so as to achieve the dehydration purpose.

[0036] When the user uses the washing equipment, the extrusion cover 22 can be removed from the outer thread structure 211, so as to expose the space in the barrel, and facilitate the user to put the washing object into the washing barrel 1 (before the washing equipment is turned off at the end of each washing, the extrusion cover 22 is actively lifted to the top end, so that the user can directly take out the extrusion cover 22 from the washing barrel 1). After the putting is completed, the extrusion cover 22 can be put back into the washing barrel 1 and be sleeved on the top end of the outer thread structure 211, so that the washing equipment can drive the extrusion cover 22 to extrude or press the washing object when washing (or dehydrating).

[0037] Through the above arrangement, the shaft sleeve 21 can be driven to guide water into the washing tub 1 or repeatedly press the pressing cover 22 downward according to the working requirements by changing the rotating speed and rotating direction of the shaft sleeve 21, so that the washing assembly 2 can complete the water inletting work and the cleaning work of the to-be-washed objects at the same time, and the washing assembly 2 and the water inletting assembly are combined together, which greatly simplifies the internal structure of the washing equipment without affecting the water inletting and washing of the washing equipment.

[0038] In the above embodiment, the arrangement direction of the washing tub 1 is not limited to the vertical arrangement. When the outer cover is closed to seal the barrel opening of the washing tub 1, the washing tub 1 can also be arranged obliquely (for example, the barrel opening is arranged obliquely forward) or horizontally, as long as the arrangement direction of the washing tub 1 can not affect the pressing washing of the to-be-washed objects in the barrel.

[0039] As a preferred example, the shaft sleeve 21 is coaxially arranged with the washing tub 1, and the edge of the pressing cover 22 is arranged close to the inner side wall of the washing tub 1, so that the pressing cover 22 can move up and down along the axis of the washing tub 1, and the pressing range of the pressing cover 22 is maximized to uniformly press the to-be-washed objects at the bottom of the washing tub 1, thereby achieving the cleaning purpose.

[0040] In addition, when the Archimedes spiral shaft 212 is fixedly connected with the inside of the shaft sleeve 21, only the outer side end of a part of the spiral structure of the Archimedes spiral shaft 212 can be fixedly connected with the inner wall of the shaft sleeve 21, so that there is a gap between the Archimedes spiral shaft 212 and the inner wall of the shaft sleeve 21, which can avoid that the washing water in the water storage cavity is accidentally rolled into the washing tub 1 when the shaft sleeve 21 drives the pressing cover 22 to frequently press the to-be-washed objects in the washing working condition. Of course, when the rotating speed of the shaft sleeve 21 in the washing working condition is set to be low and the pressing frequency of the pressing cover 22 is slow by the person skilled in the art, the outer side end of the whole spiral structure of the Archimedes spiral shaft 212 can be fixedly connected with the inner wall of the shaft sleeve 21.

[0041] In a preferred embodiment, the preferred arrangement of the pressing cover 22 includes:

[0042] The inner part of the extrusion cover 22 is provided with at least one overflow hole 223 in the radial direction, the water inlet end of the overflow hole 223 is formed on the inner threaded structure 221 and communicates with the inner threaded structure 221, and the water outlet end of the overflow hole 223 is formed on the side or bottom of the extrusion cover 22 and communicates with the washing barrel 1. In the case where the extrusion cover 22 stays on the top of the shaft sleeve 21, the water inlet end of the overflow hole 223 communicates with the top port (i.e. the upper aperture of the spiral hole diameter) of the shaft sleeve 21, so that part of the washing water flowing out of the upper aperture of the spiral hole diameter in the shaft sleeve 21 can directly enter the gap between the edge of the extrusion cover 22 and the inner side wall of the washing barrel 1 and flow into the barrel, and the other part can flow into the barrel through the overflow hole 223, so that the outside of the aperture of the spiral hole diameter can form multiple water guide paths, promote the washing water flowing out of the top end of the shaft sleeve 21 to quickly fall into the washing barrel 1, optimize the water inlet efficiency, and prevent too much water from accumulating above the shaft sleeve 21 and overflowing from the top of the extrusion cover 22 to the outside of the barrel.

[0043] In addition, the middle part of the extrusion cover 22 is also provided with a guide hole 224 and an extrusion chamber 225, the guide hole 224 is arranged below the inner threaded structure 221, the extrusion chamber 225 is arranged below the guide hole 224, and the inner threaded structure 221, the guide hole 224 and the extrusion chamber 225 communicate in sequence. Among them, the aperture size of the guide hole 224 is larger than the inner diameter size of the inner threaded structure 221, so as to guide the quick screwing of the inner threaded structure 221 and the outer threaded structure 211 and assist the mutual alignment of the inner threaded structure 221 and the outer threaded structure 211 when the extrusion cover 22 is moved from the outer threaded structure 211. Of course, in actual arrangement, in addition to the through hole shape with equal aperture size everywhere, the above-mentioned guide hole 224 can also be arranged as a tapered hole with the radial size gradually increasing from top to bottom.

[0044] The extrusion chamber 225 is a downwardly arranged horn-shaped chamber groove, the top chamber opening of the extrusion chamber 225 is connected with the bottom of the guide hole 224, and the bottom chamber opening of the extrusion chamber 225 is formed on the bottom of the extrusion cover 22, so that the bottom of the extrusion cover 22 is formed with a horn-shaped chamber groove recessed inward, facilitating the extrusion of the extrusion cover 22 on the washing object through the extrusion chamber 225, expanding the contact area of the extrusion cover 22 and the washing object, and optimizing the extrusion effect of the extrusion cover 22.

[0045] As Figure 6As shown, the washing assembly 2 further comprises an impeller 23 arranged on the inner bottom of the washing tub 1, the impeller 23 is sleeved on the shaft sleeve 21 and is in clamping connection with the shaft sleeve 21. Specifically, the impeller 23 comprises a bottom disc 231 and a plurality of blades 235 arranged on the bottom disc 231, the middle part of the bottom disc 231 is provided with a shaft hole 232, and the inner wall of the shaft hole 232 is provided with a key groove 233, and the lower side of the outer side of the shaft sleeve 21 is correspondingly provided with a shaft key. In the installed state, the shaft hole 232 is sleeved on the lower part of the shaft sleeve 21, the key groove 233 and the shaft key are in clamping connection, so as to limit the rotation of the impeller 23 relative to the shaft sleeve 21, so that the shaft sleeve 21 can drive the impeller 23 to rotate synchronously when the shaft sleeve 21 rotates. The blades 235 are arranged on the top of the bottom disc 231 in the radial direction, and the plurality of blades 235 are uniformly distributed around the shaft hole 232, so that the impeller 23 can stir the washing water and the objects to be washed when the impeller 23 rotates.

[0046] Through the above arrangement, when the shaft sleeve 21 rotates, in addition to promoting the downward pressing of the pressing cover 22, the objects to be washed can also be stirred by the rotating impeller 23. The downward pressing action of the pressing cover 22 is combined with the stirring action of the impeller 23. After the pressing cover 22 is pressed and the objects to be washed are close to the bottom of the tub, the rotating impeller 23 can stir the washing water and promote the friction cleaning of the objects to be washed on one hand, and can also directly friction clean the objects to be washed on the other hand. Together with the squeezing cleaning of the pressing cover 22, the cleaning mode of rubbing and pressing washing is realized, and the cleaning efficiency and cleaning effect are improved.

[0047] Further, the height of each blade 235 of the impeller 23 gradually decreases from one end close to the shaft hole 232 to the other end (the vertical height of the blade 235 extending out of the bottom disc 231), so as to gradually enhance the stirring capacity of the impeller 23 from the edge to the center, so as to promote the overturning effect of the washing water in the area near the shaft sleeve 21, prevent the objects to be washed from staying near the shaft sleeve 21 for a long time, and to a certain extent, prevent the objects to be washed from winding around the shaft sleeve 21 and affecting the downward pressing of the pressing cover 22.

[0048] Preferably, the laundry device of the present application further comprises a siphon 6, a control module and at least one water level sensor. The number of siphons 6 can be multiple, and the multiple siphons 6 are arranged around the washing tub 1 to collectively drain the washing water in the washing tub 1, ensuring the drainage efficiency of the laundry device. Taking the arrangement of one siphon 6 as an example: the water inlet end of the siphon 6 is in communication with the bottom of the washing tub 1, the water outlet end of the siphon 6 is in communication with the outside of the washing tub 1, and the siphon point (the middle highest point of the inverted U-shaped pipe section of the siphon 6) of the siphon 6 is higher than the maximum water level height of the washing tub 1. The control module is respectively connected with each water level sensor and the driving device 3. When the number of water level sensors is multiple, each water level corresponds to one water level sensor. For example, when the laundry device is provided with one low water level and one high water level, the first water level sensor 4 and the second water level sensor 5 are respectively arranged at the low water level position and the high water level position.

[0049] Through the above arrangement, in the case of water inflow of the laundry device, when the expected water inflow amount is the low water level, the driving device 3 drives the shaft sleeve 21 to rotate rapidly, and the washing water in the water storage cavity enters the washing tub 1 through the spiral hole diameter until the first water level sensor 4 senses the liquid level height. At this time, the water inflow amount has reached the expected standard, and the control module controls the driving device 3 to adjust the water inflow rotating speed of the shaft sleeve 21 to the non-water inflow rotating speed (stopping or reducing speed) after receiving the signal of the first water level sensor 4 detecting the washing water, and the water inflow stops. When the expected water inflow amount is the high water level, the water inflow stops when the second water level sensor 5 senses the liquid level height.

[0050] In the case of water outflow of the laundry device, the driving device 3 drives the shaft sleeve 21 to rotate rapidly, and the washing tub 1 continues to fill with water. The washing water in the siphon 6 climbs along the pipe wall until the washing water in the washing tub 1 reaches the siphon point of the siphon 6. The washing water in the siphon 6 reaches the siphon point position, triggers the siphon effect, and the siphon 6 continuously drains the washing water in the washing tub 1 until all the washing water in the washing tub 1 is drained.

[0051] Through the above arrangement, the laundry device can realize precise water inflow through the water level sensor, and achieve the purpose of water outflow through the siphon 6, without the need to additionally arrange a heavy and large-area water drainage pump in the device, further simplifying the internal structure of the laundry device and reducing the overall weight of the laundry device.

[0052] Further, the plurality of water level sensors are arranged in the water inlet pipe section of the siphon 6 corresponding to the respective water level heights, for example, the first water level sensor 4 and the second water level sensor 5 are arranged in the water inlet pipe section of the siphon 6 at positions corresponding to the low water level height and the high water level height respectively, in the water inlet condition, the siphon 6 is communicated with the washing tub 1, the water inlet pipe section of the siphon 6 is synchronously water filled with the washing tub 1, in the case that the washing water entering the siphon 6 reaches the first water level sensor 4 or the second water level sensor 5, the washing tub 1 is also water filled to the low water level or the high water level. Through the above arrangement, it can avoid the washing water splashing when the washing tub 1 is water filled or the detection error rate of the water level sensor is increased when the washing water flows along the inner wall of the washing tub 1.

[0053] Preferably, the number of the limiting ribs 11 is the same as the number of the siphons 6, each of the limiting ribs 11 is provided with a containing cavity, the limiting rib 11 is provided with a through hole which communicates the containing cavity and the washing tub 1, the inner tub bottom of the washing tub 1 is provided with a concave annular water collecting groove 13, each of the containing cavities is provided with a siphon 6, and the water inlet end of each of the siphons 6 extends to the tub bottom of the washing tub 1 through the through hole on the corresponding limiting rib 11 and extends into the groove bottom of the water collecting groove 13. In this case, when the washing water at the bottom of the washing tub 1 is discharged to the last stage, the remaining washing water can be concentrated in the water collecting groove 13 and be sucked out by the siphon 6, which ensures the reliability of the washing tub 1 drainage. In order to further optimize the complete drainage effect of the laundry equipment, the water collecting groove 13 can be arranged as a circular arc shape or an inverted isosceles trapezoidal shape which is concave downward in cross section, so that the water collecting groove 13 is gradually contracted from the groove top to the groove bottom, thereby facilitating the remaining small amount of washing water to be concentrated at the groove bottom of the water collecting groove 13 and then be sucked away, and the amount of washing water remaining in the water collecting groove 13 is minimized.

[0054] As shown in Figure 4 As an example, the limiting rib 11 is a part of the side wall of the washing tub 1 which is recessed into the tub vertically, the inner part of the part of the side wall which is recessed into the tub is protruded relative to the inner side wall of the tub and used for clamping and cooperating with the clamping groove 222 of the extrusion cover 22, the outer part of the part of the side wall which is recessed into the tub is recessed relative to the outer side wall of the tub and forms the containing cavity. In actual assembly, a supporting structure for supporting and fixing the siphon 6 can also be arranged in the containing cavity, for example, a supporting cross bar 111 is arranged in the containing cavity, in the installed condition, the inverted U-shaped pipe section at the upper part of the siphon 6 is clamped on the supporting cross bar 111, and the water inlet pipe section of the siphon 6 is clamped in the through hole, so that the siphon 6 is reliably fixed and installed on the washing tub 1, the machine size of the laundry equipment is minimized, and the siphon 6 is convenient to maintain and replace.

[0055] Of course, the limiting rib 11 can be a solid protruding rib arranged on the inner side wall of the washing tub 1, in this case, the siphon 6 can be integrally arranged with the limiting rib 11 by injection molding.

[0056] Alternatively, the water inlet amount can also be calculated by a timing device or a flow sensor, so as to stop when the water in the washing tub 1 is detected to reach the expected water inlet amount. When the water inlet amount is calculated by the timing device, the water inlet speed of the rotating shaft during water inlet can be determined in advance, so as to determine how long the water inlet at the water inlet speed can reach the expected water inlet amount, and the water inlet time is accumulated by the timing device, so that the control device controls the driving device 3 to stop water inlet for the corresponding time. When the water inlet is through the flow sensor, the flow sensor can detect the current water inlet amount in the washing tub 1 in real time in combination with the water inlet process, so as to stop water inlet when the water inlet amount reaches the expected water inlet amount.

[0057] More preferably, the laundry equipment of the present application further comprises a sewage storage member 8, which is communicated with the water outlet end of the siphon 6, so as to accommodate the washing water discharged in the washing tub 1.

The top of the sewage storage member 8 is provided with a water inlet 84, in the installed case, the water outlet pipe section of the siphon 6 which is installed and arranged close to the inner side wall of the washing tub 1 is communicated with the water inlet 84, so as to allow the washing water discharged in the siphon 6 to enter the sewage storage member 8, thereby realizing the compact arrangement of the water storage member 7, the sewage storage member 8 and the washing tub 1. The purpose of the above arrangement is that the water amount stored in the water storage member 7 at one time is just for one washing cycle, as the washing proceeds and the water storage decreases, the sewage in the sewage storage member 8 will gradually increase, if the outward turning edge is not pressed by the installation bin 9, the water storage member 7 will float up in the later stage of the washing cycle, and the bottom wall thereof will contact the bottom end of the shaft sleeve 21, thereby generating friction.

[0059] Further, the top side of the water storage member 7 is provided with a concave annular chip collecting groove 83 around the accommodating hole 81, the number of the water inlets 84 is preferably multiple, and the multiple water inlets 84 are arranged on the groove bottom of the chip collecting groove 83, and each water inlet 84 is provided with a filter member, such as a filter screen arranged at the position of the water inlet 84 or a filter core clamped in the water inlet 84, the water outlet of the water outlet pipe section of the siphon 6 is communicated with the chip collecting groove 83, so that the discharged sewage in the siphon 6 can enter the sewage storage member 8 after being filtered, and the impurities in the sewage are concentrated and isolated in the chip collecting groove 83 on the top of the sewage storage member 8, preventing the long-term accumulation of dirt in the sewage storage member 8 from being difficult to clean quickly, and ensuring the cleaning convenience of the sewage storage member 8.

In this case, a sealing ring 911 is arranged between the shaft hole of the upper bin cover 91 and the shaft sleeve 21, so as to ensure the waterproof performance of the mounting bin 9. The bottom of the impeller 23 can be provided with a sink 234 corresponding to the first shaft shoulder 213, so that the first shaft shoulder 213 protruding relative to the bottom of the washing tub 1 can be accommodated in the sink 234, thereby allowing the impeller 23 to be arranged rotatably against the bottom of the washing tub 1, and preventing a gap between the impeller 23 and the bottom of the washing tub 1 from possibly clamping the laundry to be washed.

[0061] Further, the radial dimension of the mounting bin 9 is not less than the radial dimension of the washing tub 1, and the mounting bin 9 is further provided with a water guiding structure 94, which comprises a concave annular flow guiding groove 941 arranged on the top of the upper bin cover 91 and multiple flow guiding holes 942 arranged on the bottom of the flow guiding groove 941, and the water outlet pipe section of the siphon 6 is inserted into the flow guiding groove 941, and the water outlet end of the flow guiding hole 942 is communicated with the chip collecting groove 83, so that the siphon 6 is communicated to the inside of the sewage storage member 8 through the water guiding structure 94.

[0062] As a convenient assembly mode, the shell comprises three parts arranged independently, which are arranged outside the washing barrel 1, the mounting bin 9 and the sewage storage member 8 respectively, so that the washing barrel 1, the mounting bin 9 and the sewage storage member 8 can be disassembled.

At the same time, the water outlet end of the water outlet pipe section of the siphon pipe 6 extends to the outside of the barrel bottom of the washing barrel 1 and is inserted into the flow guide groove 941, the water outlet end of the flow guide hole 942 is aligned and communicated to the debris collecting groove 83, so that the flow guide groove 941, the flow guide hole 942, the debris collecting groove 83 and the water inlet 84 can form a flow guide passage between the siphon pipe 6 and the sewage storage member 8.

[0063] Of course, in the case that the siphon pipe 6 is injection molded inside the limiting ribs 11 and is not exposed to the outside, the laundry equipment in the above embodiment can also not be provided with a shell.
