Description

Technical Field

[0001] The invention belongs to the field of household washing and cleaning, and in particular relates to a separation module for a cleaning machine and the cleaning machine. Background Art

[0002] Currently, floor cleaning machines are vacuum cleaners or sweepers, which suck a mixture of dust mixed with water vapor on the bottom surface into their inner cavity. In order to separate the mixture of particles and water vapor, a separation device is currently generally used for separation.

[0003] For example, the Chinese utility model patent "Vortex Filtration Separation System and Sweeping Robot and Equipment", whose patent application number is ZL201921208546.0 (authorization announcement number is CN210612041U), discloses a vortex filtration separation system, including a filtering structure having a vortex channel cavity, a dust box structure engaged with the filtering structure, a gauze bracket for connecting the filtering structure and the dust box structure, and a HEPA bracket installed on the dust box structure; the dust box structure is provided with an installation cavity, a dust cavity connected to the installation cavity, an air inlet connected to the installation cavity, and an air outlet connected to the dust cavity; the gauze bracket is installed with a gauze, and the HEPA bracket is installed with a HEPA; the filtering structure is installed in the installation cavity, the vortex channel cavity includes a starting end and an end, and a plurality of outlets located between the starting end and the end; the starting end of the vortex channel cavity is connected to the air inlet, the outlet of the vortex channel cavity is connected to the dust cavity through the gauze bracket, and the end of the vortex channel cavity is connected to the dust cavity. The above patent uses vortex separation to achieve the separation of dust and air. However, it completely relies on the suction force of the fan, which may result in insufficient power of the rotating flow field and poor separation effect.

[0004] Therefore, it is necessary to further improve the existing separation module. Summary of the invention

[0005] The first technical problem to be solved by the present invention is to provide a separation module for a cleaning machine that accelerates the flow velocity of a rotating flow field to improve the separation capacity in view of the current status of the above-mentioned prior art.

[0006] The second technical problem to be solved by the present invention is to provide a separation module for increasing the suction capacity at the air inlet.

[0007] The third technical problem to be solved by the present invention is to provide a wet and dry dual-purpose cleaning machine.

[0008] The technical solution adopted by the present invention to solve the above-mentioned first technical problem is: a separation module for a cleaning machine, comprising

[0009] A housing having a cavity therein, wherein the cavity has an air inlet and an air outlet fluidly connected to the air inlet;

[0010] The feature is that: the air inlet is opened on the side wall of the cavity to allow air to enter the cavity laterally; the separation module also includes

[0011] The guide air duct is arranged in the cavity, along the fluid flow path, between the air inlet and the air outlet, and has a rotating flow channel inside for accelerating the rotational flow of the airflow.

[0012] In order to accelerate the rotating flow field near the air outlet and further separate the mixed airflow, the guide air duct is arranged near the air outlet. Since the mixed airflow flowing into the cavity through the tangential air inlet rotates and separates in the cavity, the flow velocity is continuously reduced in the process of flowing toward the air outlet, and the rotating flow duct accelerates the mixed airflow, which can further separate the mixed airflow.

[0013] There are many forms of forming a rotating flow channel. It can be formed by setting a spiral upward flow channel in the guide air duct, or by setting guide vanes to form the rotating flow channel. However, preferably, an internal connector is provided inside the guide air duct, and a gap is left between the internal connector and the guide air duct, and a plurality of guide vanes arranged at intervals along the circumferential direction are provided between the two. An air outlet gap is formed between two adjacent guide vanes, and each of the guide vanes is inclined in the circumferential direction or / and radial direction relative to a plane basically perpendicular to the internal connector, so that all the guide vanes are arranged in a rotational direction rotating along the direction of fluid flow as a whole, so that all the air outlet gaps form the rotating flow channel.

[0014] In order to facilitate processing, an air guide is provided in the air guide duct, and the air guide comprises the inner connector and an outer ring wall located outside the inner connector, the outer ring wall is installed on the inner wall of the air guide duct, and the guide plate is arranged between the inner connector and the outer ring wall. In this way, the air guide can be detachably installed in the air guide duct.

[0015] In order to automatically adjust the size of the air entering the cavity according to the air volume, an air inlet channel is provided at the air inlet, and the air inlet channel has an air outlet that can be opened under the action of wind force, and the periphery of the air outlet is elastic, and the air outlet always has a tendency to move in a shrinking direction under the action of its own elasticity. In this way, when the air volume is large, the air outlet is opened and more air enters the cavity. The air outlet itself is elastic, and when there is no air entering the cavity, it can well prevent the air volume in the cavity from being diverted to the air inlet channel through the air outlet.

[0016] In order to accelerate the incoming airflow, along the fluid flow path, the air inlet channel includes a first contraction section with a gradually decreasing cross-sectional area, an expansion section with a gradually increasing cross-sectional area, and a second contraction section with a gradually decreasing cross-sectional area, and the air outlet is the end opening of the second contraction section. In this way, the existence of the first contraction section first accelerates the mixed airflow of dust and air entering the air inlet channel and forms a negative pressure, so that a better mixed airflow is inhaled. The existence of the expansion section can accommodate more airflow, and then under the action of the second contraction section, the airflow is accelerated again and enters the cavity to form a rotating flow field, and large particles are settled and separated under the action of the rotating flow field.

[0017] In order to discharge the garbage in the cavity in time, a sewage outlet and a blocking member for blocking or opening the sewage outlet are provided at the bottom of the cavity.

[0018] In order to realize automatic blocking of the sewage outlet, an elastic member is also included which acts on the blocking member and always makes the blocking member have a downward movement tendency.

[0019] In order to guide the garbage deposited in the guide air duct into the containing cavity in time, the air inlet channel is located above the blocking member, a guide plate is arranged between the guide air duct and the blocking member, a gap is left between the guide plate and the guide air duct, and the guide plate is arched upward near the middle position.

[0020] In order to better mix and aggregate the mixed airflow entering the cavity, the shell has a mixing channel upstream of the air inlet along the fluid flow path.

[0021] The technical solution adopted by the present invention to solve the above second technical problem is: the mixing channel has a reduction section adjacent to the air inlet, the cross-sectional area of ​​which gradually decreases along the air flow path.

[0022] The technical solution adopted by the present invention to solve the above-mentioned third technical problem is: a cleaning machine with the above-mentioned separation module, characterized in that: it also includes a cleaning module and a fan, along the air flow path, the separation module is located between the cleaning module and the fan, and the mixing channel of the separation module is connected to the outlet of the cleaning module, and the exhaust port of the separation module is connected to the inlet of the fan.

[0023] In order to clean the dust on the object to be cleaned in time, the cleaning module includes a shell, the interior of the shell is formed with an air guide channel connected to the mixing channel, the air guide channel has a dust suction port and the outlet, and the brush head is arranged at the dust suction port of the air guide channel.

[0024] In order to wet the stubborn stains on the cleaning object, there are multiple air guide channels, which are arranged side by side and spaced apart, and a liquid guide channel is provided between two adjacent air guide channels, and the liquid guide channel has a liquid outlet facing the object to be cleaned. When the stubborn stains on the object to be cleaned are wetted, they are easier to clean up after being brushed by the brush, thereby improving the cleaning effect.

[0025] In order to achieve water discharge from multiple diversion channels at the same time, a liquid supply component and a pressure equalizing chamber are also included. Along the flow direction of the water, the pressure equalizing chamber is located between the liquid diversion channel and the liquid supply component, and the pressure equalizing chamber has a drainage outlet respectively connected to the inlet of each of the liquid diversion channels.

[0026] Compared with the prior art, the advantages of the present invention are that the separation module for the cleaning machine has a rotating flow channel in the cavity, which can further accelerate the rotating flow field of the mixed airflow in the cavity, and particles with heavier specific gravity in the mixed airflow such as dust and air are further separated under the action of their own gravity and their own rotating flow field, and the separated airflow can quickly rise to the exhaust port for discharge, thereby improving the separation effect.

[0040] The present invention is further described in detail below with reference to the accompanying drawings.

[0041] like Figures 1 to 4 As shown, the cleaning machine of the embodiment of the present invention is a sweeper, and the object to be cleaned is the ground. The sweeper includes a cleaning module 01, a fan 5, and a separation module 04 for separating a mixture of water and dust. Along the airflow path, the separation module 04 is located between the cleaning module 01 and the fan 5. The air inlet 400 of the separation module 04 is connected to the outlet 113 of the air guide channel 11 of the cleaning module 01, and the exhaust port of the separation module 04 is connected to the inlet fluid of the fan 5. Under the action of the fan 5, a negative pressure will be formed in the cleaning module 01 and the separation module 04, so that dust, water and other garbage are sucked into the cleaning module 01 through the dust suction port 111, and then the gas separated by the separation module 04 is discharged. For details of the fluid flow path, please refer to Figure 2 The hollow arrow points to the direction.

[0042] like Figures 2 to 8 As shown, the separation module of this embodiment includes a shell 4, a guide air duct 45, an air guide member 46, an air inlet channel 47, a blocking member 48, an elastic member and a mixing channel 49.

[0043] Along the fluid flow path, such as Figure 6 As shown, the housing 4 has a cavity 41 inside, and the cavity 41 has an air inlet 400 and an air outlet 401 in fluid communication with the air inlet 400, wherein the air inlet 400 is used to allow wind to enter the cavity 41 tangentially, and the air inlet 400 is basically tangentially opened on the side wall of the cavity 41, and the air outlet 401 is opened on the top wall of the housing 4, and a filter 43 covering the air outlet 401 is installed on the air outlet 401. The housing 4 has a mixing channel 49 located upstream of the air inlet 400, and the mixing channel 49 has a reduction section 491 with a gradually decreasing cross-sectional area along the air flow path adjacent to the air inlet 400, so as to accelerate the airflow entering the air inlet 400.

[0044] like Figure 6 As shown, an air inlet channel 47 is provided at the air inlet 400, one end of the air inlet channel 47 is located in the reduction section 491, and the other end of the air inlet channel 47 is located in the cavity 41. In order to automatically adjust the air volume entering the cavity according to the air volume, as shown in FIG. Figure 6 and Figure 8 As shown, along the fluid flow path, the air inlet channel 47 includes a first contraction section 471 with a gradually decreasing cross-sectional area, an expansion section 472 with a gradually increasing cross-sectional area, and a second contraction section 473 with a gradually decreasing cross-sectional area, and the end opening of the second contraction section 473 is an air outlet 4731. The air inlet channel 47 is elastic as a whole, so the air outlet 4731 of the air inlet channel 47 can be opened under the action of wind, and the air outlet 4731 always has a tendency to move in a shrinking direction under the action of its own elasticity, so that when no air volume enters the cavity, it can well prevent the air volume in the cavity from being diverted to the mixing channel.

[0045] like Figures 2 to 4 As shown, the guide air duct 45 is located in the cavity 41 and is arranged adjacent to the exhaust port 401. Specifically, the guide air duct 45 is formed by extending downwardly from the periphery of the exhaust port 401, and is located downstream of the air inlet 400 along the fluid flow path, and is in fluid communication with the air inlet 400. Figures 2 to 4 As shown, the guide air duct 45 has a rotating flow channel inside for accelerating the rotation of the airflow. Fig. 9 As shown, an air guide member 46 is arranged in the air guide duct 45, and the air guide member 46 includes a vertically arranged inner connector 461 and an outer annular wall 463 located on the periphery of the inner connector 461, and the outer annular wall 463 is installed on the inner wall of the air guide duct 45, and a plurality of guide vanes 462 arranged at intervals along the circumferential direction are arranged between the inner connector 461 and the outer annular wall 463, and an air outlet gap 460 is formed between two adjacent guide vanes 462, and each guide vane 462 is inclined in the circumferential direction or / and radial direction relative to a plane basically perpendicular to the inner connector 461, and the angles formed are all the same acute angle, so that all the guide vanes 462 are arranged in a rotational direction rotating along the fluid flow direction as a whole, and then all the air outlet gaps 460 form a rotating flow channel rotating along the airflow flow direction.

[0046] The separated particles with a higher specific gravity are deposited at the bottom of the chamber 41. In order to conveniently discharge the deposited sewage and garbage in the chamber, the discharge path is as shown in FIG. Figure 4In the direction indicated by the solid arrow, the bottom of the chamber 41 is provided with a sewage outlet 411 and a plugging member 48 for blocking or opening the sewage outlet 411. The plugging member 48 is a flexible plug that can block the sewage outlet 411. The plugging member is located below the air inlet channel 47, and the upper end of the plugging member is open. In order to guide the mixed airflow into the guide air duct, a guide plate 451 is provided between the guide air duct 45 and the plugging member. A gap is left between the guide plate 451 and the guide air duct 45 for the mixed airflow to enter the guide air duct 45, and the guide plate 451 is arched upward near the middle.

[0047] The plug moves upward under the action of external force to open the drain outlet 411. In order to make the plug automatically block the drain outlet, the elastic member acts on the plug and always makes the plug have a tendency to move downward to block the drain outlet 411. Figures 2 to 4 As shown, the elastic member is a spring 44 located between the plug and the guide plate 451, and the two ends of the spring 44 are respectively against the guide plate 451 and the bottom plate of the plug. During use, after the sweeper enters the base station, the plug moves upward under the upward push of the pusher in the base station, so that the sewage outlet 411 is in an open state. For details, see Figure 4 shown.

[0048] like Figures 1 to 3 , Figure 5 , Figures 10 to 13 As shown, the cleaning module 01 includes a housing 1 and a driving mechanism. The housing 1 has an air guide channel 11 connected to the mixing channel 49 of the separation module. The air guide channel 11 has an outlet 113 and a dust suction port 111 with an opening facing downward. The plane where the dust suction port 111 is located is basically a horizontal plane. Specifically, a vent 492 connected to the air guide channel 11 is provided on the mixing channel 49. In this embodiment, there are four air guide channels 11 that are independent of each other and arranged side by side at intervals, and each air guide channel 11 corresponds to a vent 492.

[0049] like Figure 1 and Fig.10 As shown, a liquid guiding channel 12 is disposed between two adjacent air guiding channels 11, and the liquid guiding channel 12 has a liquid outlet 121 opening downward. Figure 1 , Figure 5 and Fig.10 As shown, the cross section of the air guide channel 11 is substantially circular, and an air inlet 112 is provided on the periphery of the dust suction port 111. Fig.10As shown, a sealing strip 16 is installed on the periphery of the dust suction port 111. The sealing strip 16 is provided with a baffle 161 at a position corresponding to the air inlet 112, which can at least partially cover the air inlet 112 and can move along the air flow direction to reduce the area of ​​the air inlet 112 covered. In this way, the baffle 161 moves relative to the air inlet under the action of the air intake volume to achieve the purpose of adjusting the size of the air inlet 112. In order to support the cleaning module, such as Figure 1 and Fig.10 As shown, a support wheel 117 is provided on the bottom surface of the housing 1 near the air inlet 112. The existence of the support wheel 117 can keep a fixed gap between the sealing strip 16 and the ground. The outlet 113 is provided at a position near the top of the air guide channel 11. The top edge of the air inlet 112 is substantially flush with the bottom edge of the outlet 113 or the top edge of the air inlet 112 is lower than the bottom edge of the outlet 113, and the distance between the top edge of the air inlet 112 and the bottom edge of the outlet 113 is 1 to 2 mm.

[0050] The brush head 13 is used to sweep and mop the floor. Figure 1 , Figure 5 , Fig.10 As shown, the brush head 13 is arranged at the dust suction port 111 of the air guide channel 11, and the brush head 13 is located in the center of the air guide channel 11, and there is a gap between the outer circumference of the brush head 13 and the inner circumferential wall of the air guide channel 11, and the brush head 13 rotates around its own rotation axis under the drive of the driving mechanism. Figure 8 As shown, the driving mechanism is a motor 14 arranged on the housing 1, and the output shaft of the motor 14 extends vertically and is basically perpendicular to the plane where the dust suction port 111 is located. The top wall of the air guide channel 11 is recessed downward to form a cavity 103 for accommodating the motor 14, and the cavity 103 is provided with a through hole for the output shaft of the power supply machine 14 to pass downward into the air guide channel 11.

[0051] Specifically, the brush head 13 includes a connecting plate 131 and at least two movable plates 132. The connecting plate 131 is arranged substantially horizontally and connected to the output shaft of the motor 14. The connecting plate 131 rotates substantially horizontally around the output shaft of the motor 14 under the drive of the motor 14. The axis of the output shaft of the motor 14 is the rotation axis of the brush head 13. In this embodiment, there are 6 movable plates 132, which are arranged at intervals along the circumferential direction on the periphery of the axis of the connecting plate 131. A first brush column 1321 is provided on the inner surface of each movable plate 132 facing the axis of the brush head 13. In a natural state, as shown in FIG. Figure 5 and Fig.12 As shown, the movable plate 132 is arranged vertically, the first brush column 1321 is arranged substantially horizontally, and the upper end of the movable plate 132 is rotatably connected to the connecting plate 131, as shown in FIG. Fig.10 and Fig.13As shown, the lower end of the movable plate 132 can be expanded outwards during the rotation of the connecting plate 131 to a state where the inner surface of the movable plate 132 faces downwards, that is, the first brush column 1321 is vertically arranged, and the free end of the first brush column 1321 can contact the ground. In this way, in a non-working natural state, the first brush column does not contact the object to be cleaned, reducing the contact area with the object to be cleaned and reducing the resistance encountered by the subsequent cleaning machine during walking. In a working state, the movable plate is expanded outwards under the centrifugal force of high-speed rotation. At this time, the first brush column contacts the ground, increasing the contact area with the ground. In order to increase the sweeping and mopping area, as shown in FIG. Fig.10 As shown, a second brush column 1312 extending downward is provided at the center of the bottom of the connecting plate 131. The second brush column 1312 has multiple pieces and is arranged at intervals along the circumferential direction. In a natural state, the first brush column 1321 is located at the periphery of the second brush column 1312, which avoids the situation that the inner periphery of the first brush column is not cleaned, making the sweeping and mopping cleaner. In a natural state where the connecting plate 131 is not rotating, the movable plate 132 can automatically restore its original state. The movable plate 132 is elastic, and the movable plate 132 has a tendency to always remain vertical under the action of its own elasticity.

[0052] like Figure 1 , Figure 5 and Fig.10 As shown, an impeller 15 is provided in each air guide channel 11. The impeller 15 is mounted on the output shaft of the motor 14. Therefore, the impeller 15 and the brush head 13 are coaxially arranged. The impeller 15 includes a wheel disc 151 and blades 152. The outer peripheral edge of the wheel disc 151 has an annular wall 1511 extending upward. There are multiple blades 152 arranged on the outer wall surface of the annular wall 1511 at intervals along the circumferential direction. The wheel disc 151 is provided with multiple water holes 1512 that penetrate the wall thickness of the wheel disc 151. In this embodiment, the multiple number is at least 3. The lowest edge of the above-mentioned blade 152 is located below the connecting plate 131 of the brush head, and the highest edge of the blade 152 is located above the connecting plate 131. Due to the existence of the impeller, when rotating, the blade can make the flow field in the air guide channel generate airflow lift flowing in the direction of the air outlet of the air guide channel when rotating at high speed. In this way, after the brush head finishes brushing, the brushed garbage can be sucked away in time, which increases the dust collection effect and makes the movable plate easier to unfold. As shown in FIG. Figure 5 As shown, the lower surface of the wheel disc 151 of the impeller 15 has an upwardly recessed receiving groove 1513, and the connecting plate 131 is fixed in the receiving groove 1513. In this way, the brush head and the impeller 15 are relatively fixedly connected. Then, under the drive of the motor 14, the impeller 15 and the brush head 13 can rotate with the output shaft of the motor 14.

[0053] like Figure 3 and Figure 5As shown, along the direction of water flow, the pressure equalizing chamber 7 is located between the liquid conducting channel 12 and the liquid supply assembly 6, so as to allow liquid to flow out of the four liquid conducting channels 12. The aforementioned liquid supply assembly 6 includes a water tank 61 and a water pump (not shown). The water tank 61 is provided with a water inlet for replenishing water into the water tank 61. The water inlet end of the water pump is connected to the water tank 61, and the water outlet end of the water pump is connected to the pressure equalizing chamber 7, so as to pump water into the pressure equalizing chamber 7. The pressure equalizing chamber 7 has a drain port 711 respectively connected to the inlet of each liquid conducting channel 12. The vertical in the above description and claims includes but is not limited to vertical, and the substantially horizontal includes completely horizontal, but is not limited to completely horizontal, and can be slightly deviated from the horizontal.

[0054] In the specification and claims of the present invention, terms indicating directions, such as "front", "rear", "up", "down", "left", "right", "side", "top", "bottom", etc., are used to describe various exemplary structural parts and elements of the present invention, but these terms are used here only for the purpose of convenience of description and are determined based on the exemplary orientations shown in the accompanying drawings. Since the embodiments disclosed in the present invention can be arranged in different directions, these terms indicating directions are only used as explanations and should not be regarded as limitations. For example, "up" and "down" are not necessarily limited to directions opposite to or consistent with the direction of gravity.

[0055] The "fluid connection" referred to in the present invention refers to the spatial position relationship between two parts or parts (hereinafter collectively referred to as the first part and the second part respectively), that is, the fluid (gas, liquid or a mixture of the two) can flow from the first part along the flow path or / and be transported to the second part. The first part and the second part can be directly connected, or the first part and the second part can be indirectly connected through at least one third party.
