Description

Technical Field

[0001] This invention relates to the field of kitchen waste disposal, specifically to a slag-water separation device and a cleaning machine. Background Technology

[0002] With increasing environmental awareness, people are paying more attention to garbage sorting. Kitchen waste, a major category of daily waste, requires specialized treatment. If not disposed of promptly, especially in summer, it can easily breed bacteria and insects and produce unpleasant odors. Therefore, many people choose the convenient garbage disposer to handle kitchen waste. Currently, most garbage disposers on the market are direct-discharge type, typically installed at the sink drain. Kitchen waste is poured into the disposer for cutting and mixing before being discharged into the drainpipe. This method easily causes blockages in the drainpipe. If many direct-discharge garbage disposers are installed in a community, it can lead to drainage problems. To address this, some companies have developed garbage disposers with drying functions.

[0003] For example, Chinese utility model patent CN201921630698.X discloses "A Kitchen Waste Disposer". An outer cover is hinged to the upper part of the fixed cover, and a touch button is provided in the outer cover. This touch button is connected to a control box, which is fixed inside the lower part of the main body shell. A pulverizing chamber is embedded in the main body shell above the control box. The fixed cover is embedded in the upper port of the pulverizing chamber, and the periphery of the fixed cover is attached to the upper surface of the kitchen countertop. A cleaning nozzle is connected through the upper part of the inner wall of the pulverizing chamber. This cleaning nozzle is connected through a water inlet pipe. The inlet end of the water inlet pipe passes through the lower side wall of the main body shell and is connected to the kitchen water source. A solenoid valve is provided on the water inlet pipe, and this solenoid valve is connected to the control box.

[0004] Although this garbage disposal unit not only functions as a food waste pulverizer but also separates solids from water, effectively reducing the incidence of sewer blockages, it is only suitable for food waste with less residual water, such as vegetable leaves, leftover rice, and leftover dishes. It is difficult to handle food waste with more residual water. Furthermore, the residue left after processing by the direct-discharge garbage disposal unit is not easy to collect, making it inconvenient to use. Summary of the Invention

[0005] The first technical problem to be solved by the present invention is to provide a slag-water separation device that facilitates the collection of residues, in light of the current state of the prior art.

[0006] The second technical problem to be solved by the present invention is to provide a slag-water separation device that effectively squeezes out residue to discharge excess water, in light of the current state of the prior art.

[0007] The third technical problem to be solved by the present invention is to provide a cleaning machine with the above-mentioned slag-water separation device, in view of the current state of the prior art.

[0008] The technical solution adopted by the present invention to solve the first technical problem mentioned above is: a slag-water separation device, comprising:

[0009] The shell has a hollow interior forming a cavity. The cavity has an outlet, an inlet for communicating with the water tank cavity, and an outlet for communicating with the downstream grinder. Along the direction of fluid flow, the outlet is located downstream of the inlet.

[0010] The inlet is located diagonally above and offset from the outlet, and also includes:

[0011] A pusher plate is disposed within the cavity and arranged below the inlet. The pusher plate can move closer to or further away from the outlet, and pushes the residue to the outlet when it is close to the outlet.

[0012] To ensure smooth drainage of the slag-water separation device, preferably, the cavity includes a collection chamber for collecting residue and a draining chamber arranged parallel to the collection chamber. The inlet and outlet are both located in the draining chamber, and the outlet is located below the inlet and communicates with the inlet to form a draining channel. The outlet is located in the collection chamber. This layout of the inlet and outlet ensures that the draining channel is vertically connected, and the residual water to be discharged will not be blocked by any part, thus ensuring smooth drainage.

[0013] To ensure preliminary filtration of the residue, preferably, a first slag basket is also provided in the draining chamber, the first slag basket having a plurality of draining holes spaced apart, and the push plate is located inside the first slag basket.

[0014] There are various ways to achieve the movement of the push plate. Preferably, the housing is further provided with a first driver, which is arranged around the periphery of the cavity and the power output end is connected to the push plate drive.

[0015] The power of the first driver can be transmitted to the push plate in different ways. Preferably, the housing is also provided with a screw, which is rotatably arranged in the drain chamber and passes through the push plate, thereby driving the push plate to move. Furthermore, the extension direction of the screw intersects with the fluid flow direction in the drain channel.

[0016] To ensure sufficient driving force when the first driver transmits it to the push plate, preferably, a mounting base is provided on the side of the housing, the first driver is located at the bottom of the mounting base and extends upward in the output axis, the screw is provided with a first transmission tooth at the corresponding end, and a second transmission tooth is provided on the output shaft of the first driver. The screw is driven by the meshing of the first transmission tooth and the second transmission tooth to rotate around its own axis under the drive of the first driver.

[0017] To ensure smooth sliding of the push plate, preferably, the screw passes through one side of the push plate, and a guide rod is also provided in the drain chamber, the guide rod extending in the same direction as the screw and passing through the other side of the push plate.

[0018] The drain chamber and the collection chamber are connected by a central opening. The collection chamber is also equipped with a sealing side plate, which can seal the opening and can open or close the opening.

[0019] To further address the second technical problem mentioned above, the technical solution adopted by this invention is as follows: the sealing side plate is arranged to move away from the opening, thereby allowing the sludge-water separation device to operate in two states:

[0020] In the draining state, the sealing side plate seals the opening, and the push plate moves to abut against the sealing side plate, forming a gap between the push plate and the sealing side plate to squeeze out residual water.

[0021] In the collection state, the sealing side plate moves to the side of the shell away from the opening, and the bottom of the drain chamber is connected to the collection chamber to form a channel for the pusher plate to push the squeezed residue into the discharge outlet. This design of the sealing side plate artificially divides the residue processing into two stages. In the first stage, the pusher plate squeezes the residue onto the sealing side plate, realizing the active discharge of residual water. At this time, the sealing side plate is sealed at the opening, and the entire process of residual water discharge is limited to the drain chamber, and the squeezed water is directly discharged through the drain channel. The second stage is the dust collection and treatment of the squeezed residue, that is, the pusher plate continues to push forward until the residue enters the discharge outlet. At this time, the sealing side plate moves to a position away from the opening, providing sufficient clearance for the pusher plate to move.

[0022] To ensure the sealing effect of the sealing side plate and prevent water leakage during compression, preferably, the inner wall of the cavity extends inward with a circumferentially extending annular baffle. In the draining state, the sealing side plate abuts against the annular baffle, and an annular sealing ring is provided on the periphery of the sealing side plate at a position opposite to the annular baffle. This design of the annular baffle and sealing ring not only achieves surface sealing at the side wall of the sealing side plate and the annular baffle, but also improves the sealing effect on the basis of surface sealing by means of the annular sealing ring, thereby preventing water leakage or even the infiltration of water droplets.

[0023] To ensure that the sealing side can move, preferably, a second driver is also provided in the collection chamber, and the power output end of the second driver is driven to be connected to the sealing side plate, thereby driving the sealing side plate to move.

[0024] To ensure that water containing residue can be drained into the cavity, the residue-water separation device also includes a drain assembly installed at the water inlet and at least partially located inside the dishwasher's water tank.

[0025] Preferably, the drainage assembly includes a cover, a drainage seat, and a second slag basket arranged sequentially from top to bottom. The outer edge of the drainage seat has a first retaining edge for installation with the bottom wall of the washing machine. The drainage seat has an opening at the top and a hollow interior forming an inner cavity. The cover is detachably installed over the opening of the inner cavity. The second slag basket is detachably installed at the bottom of the drainage seat. The detachable design of the second slag basket allows for selection of whether the entire slag-water separation device is activated as needed. When slag-water separation is not required, simply installing the second slag basket will intercept most of the residue, which can then be directly dumped for disposal.

[0026] To prevent accidental opening of the cover when handling residue, the drain assembly preferably includes a locking mechanism. When the cover is positioned over the opening of the inner cavity, the output end of the locking mechanism acts on the side wall of the cover to prevent the cover from detaching from the opening.

[0027] Specifically, the locking mechanism includes a locking cylinder and a locking lever. The locking lever is connected to the output end of the locking cylinder and can move radially along the cover under the action of the locking cylinder. The side wall of the cover protrudes outward at the bottom to form a second stop. When the cover is placed over the opening of the inner cavity, the locking lever moves to the upward path of the second stop.

[0028] There are various ways to lock the cover. Preferably, the locking rod has an arc-shaped structure with both ends bent towards the same side, and the concave surface of the arc-shaped structure matches the outer wall of the cover.

[0029] A triggering mechanism is also provided around the lower water seat. The triggering mechanism has a bracket and a contact piece. The contact piece extends into the inner cavity and is electrically connected to the first driver, the second driver, and the locking cylinder. When the cover is placed on the lower water seat, the lower edge of the cover contacts the contact piece.

[0030] To further solve the third technical problem mentioned above, the technical solution adopted by the present invention is as follows: a cleaning machine with the above-mentioned slag-water separation device, comprising a box, a water tank and a grinder, wherein the inside of the box is hollow to form a cleaning chamber, the water tank is arranged side by side with the box, the shell is installed below the water tank, and the grinder is installed at the outlet.

[0031] Compared with the prior art, the advantages of the present invention are as follows: In this slag-water separation device, the residual water can be discharged smoothly through the combined action of the inlet and outlet of the cavity. The staggered arrangement of the inlet and outlet can separate the collection and drainage of the residue for separate processing. At the same time, the intermittent pushing of the push plate can drive the push plate to centrally process the residue when needed. Compared with the traditional direct discharge method, the waste treatment method is more flexible. The storage of residue is no longer limited by the vertical discharge structure. Whether it is subsequent drying or collection of residue, it is more convenient and very practical. Attached Figure Description

[0038] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0039] like Figures 1 to 6As shown, this is a preferred embodiment of the present invention. In this embodiment, the slag-water separation device is suitable for use in a cleaning machine. The cleaning machine mentioned here includes a housing 100, a water tank 2, and a grinder 3. The housing 100 is hollow inside to form a cleaning chamber. The water tank 2 is arranged side by side with the housing 100. The slag-water separation device in this embodiment specifically includes a shell 1 and a push plate 4. The shell 1 is hollow inside to form a cavity 10. The cavity 10 has an outlet 1b, an inlet 1a for communicating with the cavity of the water tank 2, and an outlet 1c for communicating with the downstream grinder 3. Along the flow direction of the fluid, the outlet 1b is arranged downstream of the inlet 1a. When combined with the cleaning machine, the shell 1 is installed below the water tank 2, and the grinder 3 is installed at the outlet 1c.

[0040] In this embodiment, the collection of drain water and residue is divided into two independent stages. Structurally, the aforementioned cavity 10 includes a collection chamber 12 for collecting residue and a drain chamber 11 arranged parallel to the collection chamber 12. Both the inlet 1a and the outlet 1b are located in the drain chamber 11. The outlet 1b is located below the inlet 1a and communicates with the inlet 1a to form a drain channel. The outlet 1c is located in the collection chamber 12. That is, the inlet 1a is located diagonally above the outlet 1c and is offset from the outlet 1c. This staggered design separates the residue collection and drainage processes, enabling better separation of residue and water and avoiding the awkward situation of residue and water mixing during direct discharge.

[0041] In this embodiment, the pusher plate 4 is disposed in the cavity 10 and arranged below the inlet 1a. The pusher plate 4 can approach or move away from the outlet 1c, and pushes the residue to the outlet 1c when it is close to the outlet 1c. It is the above-mentioned draining and discharge structure that provides the prerequisite for the pusher plate 4 to push out. Functionally, by using the intermittent pushing of the pusher plate 4, the pusher plate 4 can be driven to centrally process the residue when needed. Compared with the traditional direct discharge form, the waste treatment method is more flexible. The storage of residue is no longer limited by the vertical discharge structure, and it is more convenient to dry or collect the residue later.

[0042] Specifically, the aforementioned draining chamber 11 is further provided with a first slag basket 5, which has multiple drain holes spaced apart. A pusher plate 4 is disposed within the first slag basket 5. Of course, the movement of the pusher plate 4 requires a corresponding power source. In this embodiment, the aforementioned housing 1 is also provided with a first driver 61, which is arranged around the periphery of the cavity 10, and its power output end is connected to the pusher plate 4. Furthermore, a screw 62 is also provided on the housing 1. This screw 62 is rotatably arranged within the draining chamber 11 and passes through the pusher plate 4, thereby driving the pusher plate 4 to move. The extension direction of the screw 62 intersects the fluid flow direction in the draining channel. In this embodiment, a mounting base 63 is provided on the side of the housing 1. A first driver 61 is located at the bottom of the mounting base 63 and extends upward along its output axis. A screw 62 has a first transmission tooth 64 at its corresponding end, and a second transmission tooth 65 is provided on the output shaft of the first driver 61. The screw 62 rotates around its own axis under the drive of the first driver 61 through the meshing of the first transmission tooth 64 and the second transmission tooth 65. The screw 62 passes through one side of the push plate 4, and a guide rod 66 is also provided in the draining chamber 11. The guide rod 66 extends in the same direction as the screw 62 and passes through the other side of the push plate 4.

[0043] While the pusher plate 4 performs the aforementioned pushing action, it also has the function of squeezing the residue to achieve active drainage. In order to cooperate with the force exerted by the pusher plate 4, the draining chamber 11 and the collection chamber 12 in this embodiment are connected through the central opening. The collection chamber 12 is also provided with a sealing side plate 13, which seals the opening and can move away from the opening, thereby enabling the sludge-water separation device to be in two operating states:

[0044] In the draining state, the sealing side plate 13 is sealed at the opening, and the push plate 4 moves to abut against the sealing side plate 13, forming a gap between the push plate 4 and the sealing side plate 13 to squeeze out residual water.

[0045] In the collection state, the sealing side plate 13 moves to the side of the housing 1 away from the opening, and the bottom of the drain chamber 11 communicates with the collection chamber 12 to form a channel for the pusher plate 4 to push the squeezed residue into the outlet 1c.

[0046] The sealing structure can take different forms. In this embodiment, the inner wall of the cavity 10 has a circumferentially extending annular baffle 14. In the draining state, the sealing side plate 13 abuts against the annular baffle 14, and an annular sealing ring 15 is provided on the periphery of the sealing side plate 13 at a position opposite to the annular baffle 14. This design of the annular baffle 14 and the sealing ring 15 not only achieves surface sealing at the side walls of the sealing side plate 13 and the annular baffle 14, but also improves the sealing effect on the basis of surface sealing with the help of the annular sealing ring 15, thereby preventing water leakage or even the infiltration of water droplets. In addition, the movement of the sealing side plate 13 requires an independent drive source. A second driver 16 is also provided in the collection chamber 12. The power output end of the second driver 16 is connected to the sealing side plate 13, thereby driving the sealing side plate 13 to move.

[0047] To ensure that the mixture of sludge and water in the water tank can enter the sludge-water separation device, the sludge-water separation device also includes a drain assembly 7, which is installed at the water inlet 1a and is at least partially located inside the water tank 2 of the dishwasher. In this embodiment, the drain assembly 7 includes a cover 71, a drain seat 72, and a second sludge basket 73 arranged sequentially from top to bottom. The outer edge of the drain seat 72 has a first retaining edge 75 for mounting to the bottom wall of the washing machine. The drain seat 72 has an open top and a hollow interior forming an inner cavity 70. The cover 71 is detachably installed over the opening of the inner cavity 70, and the second sludge basket 73 is installed at the bottom of the drain seat 72. In addition, the drain assembly 7 also includes a locking mechanism 74. When the cover 71 is installed over the opening of the inner cavity 70, the output end of the locking mechanism 74 acts on the side wall of the cover 71 to prevent the cover 71 from detaching from the opening. Specifically, the locking mechanism 74 includes a locking cylinder 741 and a locking lever 742. The locking lever 742 is connected to the output end of the locking cylinder 741 and can move radially along the cover 71 under the action of the locking cylinder 741. The side wall of the cover 71 protrudes outward at the bottom to form a second stop 76. When the cover 71 is placed over the opening of the inner cavity 70, the locking lever 742 moves onto the upward path of the second stop 76. In this embodiment, the locking lever 742 has an arc-shaped structure with both ends bent towards the same side, and the concave surface of the arc-shaped structure matches the outer wall of the cover 71.

[0048] Furthermore, for locking and unlocking the cover 71, an independent triggering mechanism 77 is provided on the periphery of the lower water seat 72. The contact piece 78 in the triggering mechanism 77 is located on the periphery of the lower water seat 72 and extends into the inner cavity 70. When the cover 71 is placed on the lower water seat 72, the cover 71 contacts the contact piece 78 and connects the circuit corresponding to the contact piece 78, thereby providing different electrical signals to the locking cylinder 741, the first driver 61, and the second driver 16, so that the push plate 4 and the sealing side plate 13 can achieve different movement modes at different time stages, thereby realizing different actions such as slag-water separation and squeezing. Since the electrical signal transmission and control part is not the focus of this application, the connection, structure, and model of the controller and the electrical components that implement each control part will not be described in detail here. For details of the actions of the push plate 4 and the sealing side plate 13 at different stages, please refer to "Working Process".

[0049] Work process:

[0050] 1. Sludge-water separation:

[0051] The second slag basket 73 can be selectively installed on the drain seat 72 as needed. If the second slag basket 73 is installed, water flows out and is discharged from the drain holes of the second slag basket 73 and the first slag basket 5, while the residue remains in the second slag basket 73. If deep separation is not required, the second slag basket 73 can be removed directly and the residue poured out. If separation is required, after a certain amount of residue has accumulated, the residue in the second slag basket 73 can be poured into the drain chamber 11 below, where it is received by the first slag basket 5. If the second slag basket 73 is not installed, the residue and water flow directly into the drain chamber 11. At this time, most of the water flows out and is discharged directly from the drain holes of the first slag basket 5, while the residue remains in the first slag basket 5. The purpose of setting up the second slag basket 73 is to provide users with more diverse and flexible residue handling modes. In the event of non-kitchen waste falling, the second slag basket 73 can be directly processed and recycled, avoiding damage to the downstream grinder 3.

[0052] 2. Residue Transfer

[0053] In the aforementioned stages, regardless of whether the second slag basket 73 is installed, the first slag basket 5 will collect residue in different options. When the cover 71 is closed, it contacts the contact piece 78 in the trigger mechanism 77. The locking cylinder 741 in the aforementioned locking mechanism 74 drives the locking rod 742 to abut against the side wall of the cover 71, blocking the upward movement path of the second stop 76. At this point, the cover 71 cannot be removed from the outside, and the entire drainage assembly obtains a relatively sealed inner cavity 70 space. Simultaneously, the push plate 4 in the first... Driven by the actuator 61, the residue moves towards the collection chamber 12, simultaneously squeezing the residue in the first slag basket 5 against the sealing side plate 13 sealed at the opening. The squeezing causes most of the water to flow out through the drain holes to the sides or bottom. After maintaining the squeezing action for a certain period, the sealing side plate 13 moves in the same direction as the push plate 4 (away from the opening) under the drive of the second actuator 16. The processed residue is finally pushed to the discharge port 1c and enters the downstream grinder 3 for further grinding, drying, and other processes. Alternatively, the push plate 4 can directly push the residue without squeezing it, provided the sealing side plate 13 avoids it before it reaches the appropriate position. Only the optimal process is shown here; the second case will not be elaborated further.

[0054] 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 fluid channel such as a pipe, channel, conduit, guide, hole, or groove, or a chamber or combination thereof that allows fluid to flow through.

[0055] Furthermore, the specification and claims of this invention use terms indicating direction, such as "front," "rear," "upper," "lower," "left," "right," "side," "top," and "bottom," to describe various exemplary structural parts and elements of the invention. However, these terms are used herein merely for ease of explanation and are determined based on the exemplary orientations shown in the accompanying drawings. Since the embodiments disclosed in this invention can be arranged in different orientations, these terms indicating direction are for illustrative purposes only and should not be considered as limitations. For example, "upper" and "lower" are not necessarily limited to directions opposite to or consistent with the direction of gravity.
