Description

Technical Field

[0001] This utility model relates to the field of cleaning machines, and in particular to a slag basket cleaning structure for a cleaning machine and a cleaning machine. Background Technology

[0002] Currently, dishwashers and fruit and vegetable washers are devices that spray cold or hot water onto dishes, fruits, and vegetables to remove dirt and grime. They typically include a pump and nozzles for spraying the washing water. Because dishes often have leftover food scraps or rice grains, and fruits and vegetables often have a lot of dirt on them, the washer leaves residue at the bottom of the machine after washing.

[0003] To this end, Chinese patent application CN201611095273.4, entitled "A Slag Discharge Mechanism for a Water Tank," discloses a structure that includes a slag basket and a slag crushing structure. This structure collects food scraps from the bottom of the tank and crushes them using the slag crushing structure at the bottom of the basket before discharging them. Similarly, Chinese utility model patent ZL 202321787811.1 (authorization announcement number CN220494989U) discloses a washing machine that includes a water cup with a drain outlet and a slag basket assembly located at the drain outlet.

[0004] However, while the waste basket structure offers convenience, it also presents challenges. Specifically, fine food scraps easily adhere to the basket walls, leaving a significant amount of residue after a period of use. The basket walls are typically equipped with a fine mesh screen with dense pores, making cleaning difficult. This usually requires manual disassembly and subsequent cleaning. The current methods of routine cleaning and maintenance of the waste basket severely impact the user experience of the dishwasher and urgently need improvement. Summary of the Invention

[0005] The first technical problem to be solved by this utility model is to provide a slag basket assembly for a cleaning machine that can achieve self-cleaning, in contrast to the prior art.

[0006] The second technical problem to be solved by this utility model is to provide a slag basket assembly for a cleaning machine that can achieve self-cleaning and has a good cleaning effect, in contrast to the prior art.

[0007] The third technical problem to be solved by this utility model is to provide a cleaning machine with the above-mentioned slag basket assembly, which is in contrast to the prior art.

[0008] The technical solution adopted by this utility model to solve at least one of the above-mentioned technical problems is as follows: a slag basket assembly for a cleaning machine, including a slag basket, which is disposed above a drain outlet and used to collect residue, characterized in that it further includes a spraying component, which surrounds the slag basket, and the spraying component has a water flow channel arranged along its own length direction, the two ends of the water flow channel are spaced apart from each other, and a water inlet is opened at one end, and a spray hole for spraying water toward the slag basket is also opened on the water flow channel.

[0009] Furthermore, it also includes a water cup with a recessed space, the bottom of which has the aforementioned drain outlet, and the aforementioned slag basket is disposed in the recessed space of the water cup. The aforementioned spray component is open-ring shaped, with a hollow interior forming the aforementioned water flow channel. Designing the spray component as an open ring reduces its volume, thereby reducing the space occupied inside the water cup and improving the utilization rate of the water cup's internal space; it also facilitates the setting of a water flow channel inside the spray component.

[0010] Furthermore, the spray element is arranged horizontally and has a spray gap between it and the slag basket along its length. The spray holes are formed on the inner annular wall of the spray element and include a first spray hole and a second spray hole. The opening height and extension direction of the first spray hole are different from those of the second spray hole, and the first and second spray holes are arranged circumferentially at intervals. Positioning the spray holes on the inner side of the spray element allows the water in the spray holes to be sprayed more effectively onto the slag basket. Specifically, setting the spray holes as first and second spray holes with different opening heights and extension directions helps reduce blind spots in the spraying process, expands the spraying range over the slag basket, and thus improves the cleaning effect on the slag basket.

[0011] Furthermore, the lower peripheral wall of the slag basket is covered with a slag mesh, and the aforementioned spray element is positioned opposite the upper end of the slag mesh. The opening height of each of the first spray holes is higher than that of each of the second spray holes, and the extension direction of each first spray hole is parallel to or upward relative to the horizontal plane, while the extension direction of each second spray hole is downward relative to the horizontal plane. This enables circumferential, vertically intersecting mesh spraying of the slag mesh in the slag basket, thoroughly rinsing away fine residue remaining on the mesh and ensuring the filtration effect of the slag basket. The downward extension direction of the lower-height second spray holes helps prevent residue from clogging the channels during rinsing. Additionally, the staggered height design of the first and second spray holes also helps reduce residue accumulation at each spray hole.

[0012] Furthermore, the outer surface of the inner annular wall of the spray element extends vertically and its lower end slopes outward from top to bottom along its length to form a spray slope. Each of the first spray holes and the second spray holes is arranged on this spray slope. The spray slope can guide the residue splashed onto the spray element during rinsing to the lower part of the spray element, thereby preventing the residue from clogging the spray holes.

[0013] Furthermore, the water inlet is located on the bottom wall of the spray element, while the first and second spray holes are located at the lower end of the inner annular wall of the spray element. This reduces the kinetic energy loss of the water flowing into the water channel, thereby increasing the water pressure utilization rate. It also reduces water residue inside the water channel, preventing bacterial growth and odor problems caused by water residue.

[0014] Furthermore, the bottom wall of the spray element extends horizontally, and each second spray hole is respectively opened at the junction of the bottom wall and the inner annular wall of the spray element. On the one hand, this can further improve the water spraying effect of each second spray hole (benefiting from the gravity of the water flow itself), and on the other hand, it can better solve the problem of water residue inside the water flow channel.

[0015] Furthermore, the open end of the spray component is connected to the water cup, while the other parts are suspended in the air. The spray component has connecting protrusions protruding outward on both sides of its opening, and the corresponding recesses in the water cup have connecting recesses outward for the corresponding connecting protrusions to be inserted.

[0016] In the installed state, each connecting protrusion is fitted into its corresponding connecting recess and secured with fasteners. This improves the ease of installation and makes better use of the internal installation space of the water cup. The cooperation between the connecting protrusions and corresponding recesses allows for pre-positioning of the spray unit during installation, ensuring installation accuracy and reducing installation difficulty. Furthermore, separating the connection point between the spray unit and the water cup from the ring body of the spray unit prevents the fasteners from loosening due to the impact of water flow in the water channel, thus ensuring the stability of the spray unit's installation structure.

[0017] Furthermore, in the installed state of the spray component, the included angle between the fasteners on both sides of the spray component opening is 90° to 120°. This further ensures the stability of the spray component installation structure and better prevents the spray component from loosening and falling off.

[0018] Furthermore, the water inlet is located on the bottom wall of the spray element, and the edge of the water inlet extends downward in the circumferential direction to form a first water inlet connector, which is used to communicate with the water inlet on the water cup. The integrated design of the first water inlet connector and the spray element can completely eliminate the leakage problem at the water inlet. At the same time, by designing the first water inlet connector, it is possible to facilitate the communication between the water inlet and the water inlet, and on the other hand, it can allow the water to flow from bottom to top into the water flow channel of the spray element, fully converting the potential energy of the water flow into the kinetic energy of the water flow, increasing the flow velocity of the water in the water flow channel, and also helping to reduce the water pressure fluctuation in the water flow channel.

[0019] Furthermore, the water inlet is equipped with a second water inlet connector, which is inserted vertically into the first water inlet connector, and a sealing ring is clamped around the connection point of the two. This further improves the convenience of communication between the water inlet hole and the water inlet, while also preventing water leakage at the connection point.

[0020] The technical solution adopted to further solve the third technical problem mentioned above is: a cleaning machine, characterized in that it includes a slag basket assembly for the cleaning machine as described above.

[0021] Compared with existing technologies, the advantages of this invention are as follows: By setting up a spraying component, the water jet from the spray holes of the spraying component is used to spray and clean the slag basket, eliminating the need for manual cleaning and achieving self-cleaning of the slag basket. Furthermore, the two ends of the water flow channel in the spraying component are spaced apart, with a water inlet at one end, breaking the circumferential circulation flow field limitation of the closed annular channel. This forces the water to flow unidirectionally along the water flow channel, which helps to accelerate the water flow velocity, reduce turbulent energy loss within the channel, thereby improving water pressure utilization, enhancing the spraying effect of the spray holes, and ultimately improving the cleaning effect on the slag basket.

[0029] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0030] In the description of this utility model, it should be understood that the terms "center," "longitudinal," "transverse," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," "axial," "radial," and "circumferential," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Since the embodiments disclosed in this utility model can be arranged in different directions, these terms indicating direction are only for illustration and should not be regarded as limitations. For example, "upper" and "lower" are not necessarily limited to directions opposite to or consistent with the direction of gravity. In addition, features defined with "first" and "second" may explicitly or implicitly include one or more of such features.

[0031] A cleaning machine, comprising, for example Figures 1-7 The filter structure shown includes a slag basket 1, which is positioned above a drain outlet (not shown) and used to collect residue. It further includes a spray element 2, which surrounds the slag basket 1 and has a water flow channel 20 arranged along its length. The two ends of the water flow channel 20 are spaced apart, and one end has a water inlet 25. Furthermore, the water flow channel 20 also has spray holes facing the slag basket 1.

[0032] In this invention, a spray element 2 is provided, which uses water jets from the spray holes of the spray element 2 to spray and clean the slag basket 1, eliminating the need for manual cleaning and achieving self-cleaning of the slag basket 1. Furthermore, the two ends of the water flow channel 20 in the spray element 2 are spaced apart, with a water inlet 25 at one end. This breaks the circumferential circulation flow field limitation of the closed annular channel, forcing the water to flow unidirectionally along the water flow channel 20. This helps to accelerate the water flow velocity, reduce turbulent energy loss within the channel, thereby improving water pressure utilization, enhancing the spraying effect of the spray holes, and ultimately improving the cleaning effect on the slag basket 1.

[0033] Furthermore, there are various ways to implement the spray element 2. For example, the spray element can be a closed ring, and a water flow channel can be provided in the spray element, with the length of the water flow channel being shorter than the circumference of the spray element. In this embodiment, specifically, it also includes a water cup 3 with a recessed space 31, the bottom of which has the drain outlet, and the slag basket 1 is disposed in the recessed space 31 of the water cup 3. Since the internal installation space of the water cup 3 is limited, preferably, as shown in the example... Figure 4 and Figure 5 As shown, the spray element 2 has an open-ring shape, and its interior is hollow to form the water flow channel 20. Designing the spray element 2 as an open ring can reduce its volume, thereby reducing the space occupied inside the water cup 3 and improving the utilization rate of the internal space of the water cup 3; on the other hand, it is convenient to set up the water flow channel 20 inside the spray element 2.

[0034] like Figure 4 and Figure 5 As shown, the spray element 2 is arranged horizontally and has a spray gap between it and the slag basket 1 along its length. The spray holes are formed on the inner annular wall of the spray element 2 and include a first spray hole 23 and a second spray hole 24. The opening height and extension direction of the first spray hole 23 are different from those of the second spray hole 24, and the first spray hole 23 and the second spray hole 24 are arranged circumferentially at intervals. Positioning the spray holes on the inner side of the spray element 2 allows for better spraying of water into the slag basket 1. Furthermore, specifically configuring the spray holes as first spray holes 23 and second spray holes 24 with different opening heights and extension directions helps reduce blind spots, expands the spray range over the slag basket 1, and improves the cleaning effect on the slag basket 1.

[0035] Furthermore, such as Figure 4 As shown, the lower peripheral wall of the slag basket 1 is covered with a slag mesh 11, and the spray element 2 is positioned opposite the upper end of the slag mesh 11. Furthermore, the opening height of each of the first spray holes 23 is higher than that of each of the second spray holes 24, and the extension direction of each of the first spray holes 23 is parallel to or upward relative to the horizontal plane, while the extension direction of each of the second spray holes 24 is downward relative to the horizontal plane. This allows for circumferential, vertically intersecting mesh spraying of the slag mesh 11 in the slag basket 1, thoroughly rinsing away fine residue remaining on the slag mesh 11 and ensuring the filtration effect of the slag basket 1. The downward extension direction of the lower-height second spray holes 24 helps prevent residue from clogging the holes during rinsing. In addition, the staggered height design of the first spray holes 23 and the second spray holes 24 also helps reduce the accumulation of residue at each spray hole. In this embodiment, preferably, the angle between the extension direction of each first spray hole 23 and the horizontal plane is 0 to 10°, and the angle between the extension direction of each second spray hole 24 and the horizontal plane is 30° to 60°.

[0036] More preferably, such as Figure 4 and Figure 5 As shown, the outer surface of the inner annular wall of the spray element 2 extends vertically and its lower end slopes outward from top to bottom along its length to form a spray slope 26. The first spray holes 23 and the second spray holes 24 are respectively arranged on this spray slope 26. The spray slope 26 guides the residue splashed onto the spray element 2 during rinsing downwards, thereby preventing residue from clogging the spray holes.

[0037] like Figure 5 As shown, the water inlet 25 is located on the bottom wall of the spray element 2, while the first spray holes 23 and the second spray holes 24 are located at the lower end of the inner annular wall of the spray element 2. This reduces the kinetic energy loss of the water flow entering the water channel 20, thereby increasing the water pressure utilization rate. It also reduces water residue inside the water channel 20, preventing bacterial growth and odor problems caused by water residue. Preferably, the bottom wall of the spray element 2 extends horizontally, and the second spray holes 24 are located at the junction of the bottom wall and the inner annular wall of the spray element 2. This further enhances the spraying effect of the second spray holes 24 (utilizing the gravity of the water flow) and better addresses the problem of water residue inside the water channel 20.

[0038] like Figure 1 and Figure 2 As shown, the open end of the spray component 2 is connected to the water cup 3, while the other parts are suspended. The spray component 2 has connecting protrusions 27 protruding outwards on both sides of its opening, and corresponding connecting recesses 32 are recessed outwards in the recessed space 31 of the water cup 3 for the corresponding connecting protrusions 27 to be inserted. In the installed state, each connecting protrusion 27 is embedded in its corresponding connecting recess 32 and fixed by fasteners. This improves the ease of installation of the spray component 2 and allows for better utilization of the internal installation space of the water cup 3. The cooperation between the connecting protrusions 27 and the corresponding connecting recesses 32 enables pre-positioning of the spray component 2 during installation, ensuring installation accuracy and reducing installation difficulty. Furthermore, separating the connection between the spray component 2 and the water cup 3 outside the ring body of the spray component 2 prevents the fasteners from loosening due to the impact of water flow in the water channel 20, thus ensuring the stability of the spray component 2's installation structure. Preferably, in the installed state of the spray component 2, the included angle formed by the fasteners on both sides of the opening of the spray component 2 is 90° to 120°, which can further ensure the stability of the installation structure of the spray component 2 and better prevent the spray component 2 from loosening and falling off.

[0039] In this embodiment, specifically, each connecting protrusion 27 is a wing-shaped protrusion extending horizontally outward from both sides of the spray member 2, and each connecting recess 32 is a groove matching the shape of the corresponding connecting protrusion 27. Simultaneously, each connecting protrusion 27 has a fastening hole 270, and each connecting recess 32 has a vertically extending fastening sleeve 321 protruding from it. When the spray member 2 is installed, the fastening holes 270 of each connecting protrusion 27 are respectively fitted onto the corresponding fastening sleeves 321, and the aforementioned fasteners (specifically screws in this embodiment) are screwed into each fastening sleeve 321 to fix the spray member 2 to the water cup 3.

[0040] In this embodiment, as Figure 5 , Figure 6 as well as Figure 7 As shown, the spray component 2 is formed by assembling an upper cover 21 and a lower cover 22 along its length. The bottom of the upper cover 21 has an upper annular groove 210 along its length, while the top of the lower cover 22 has a lower annular groove 220 along its length. The upper annular groove 210 and the lower annular groove 220 are assembled vertically to form the water flow channel 20. Each first spray hole 23, each second spray hole 24, and each water inlet hole 25 are respectively provided on the lower cover 22, while each connecting protrusion 27 is respectively provided on the upper cover 21, and the top surface of each connecting protrusion 27 is flush with the top surface of the upper cover 21. Figure 6 As shown.

[0041] Furthermore, the aforementioned water inlet hole 25 is formed on the bottom wall of the spray component 2, and the edge of the water inlet hole 25 extends downward in the circumferential direction to form a first water inlet connector 4. The first water inlet connector 4 is used to communicate with the water inlet (not shown) on the water cup 3. The integrated design of the first water inlet connector 4 and the spray component 2 can completely eliminate the water leakage problem at the water inlet hole 25. At the same time, by designing the first water inlet connector 4, it is convenient to communicate with the water inlet hole 25 and the water inlet, and it can also make the water flow from bottom to top into the water flow channel 20 of the spray component 2, so as to fully convert the water flow potential energy into water flow kinetic energy, increase the water flow velocity in the water flow channel 20, and also help to reduce the water pressure fluctuation in the water flow channel 20. Preferably, the aforementioned water inlet is provided with a second water inlet connector 5, and the aforementioned first water inlet connector 4 and the second water inlet connector 5 are inserted vertically, and a sealing ring 6 is sandwiched at the connection between the two in the circumferential direction. This further improves the convenience of connecting the water inlet hole 25 with the water inlet, while also preventing water leakage at the connection point.

[0042] Furthermore, the cleaning machine of this invention also includes a breather assembly, a water softener assembly, and a water inlet path, which has an inlet valve. When the cleaning machine is in operation, tap water enters the breather assembly, water from the breather assembly enters the water softener assembly, and water from the water softener assembly enters the water flow channel 20 through the water inlet on the water cup 3 and the water inlet hole 25 on the spray element 2. Thus, as water enters the cleaning machine, the spray element 2 simultaneously washes the slag basket 1.

[0043] The term "fluid connectivity" as used in this invention refers to the spatial relationship between two components or parts (hereinafter referred to as the first part and the second part, respectively), that is, a fluid (gas, liquid, or a mixture of both) can flow from the first part along a flow path and / or be transported to the second part. This can be a direct connection between the first part and the second part, or an indirect connection between the first part and the second part through at least one third party. This third party can be a water flow channel such as a pipe, channel, conduit, guide, hole, or groove, or a chamber that allows fluid to flow through, or a combination of the above.
