Description

Technical Field

[0001] This application belongs to the field of cleaning technology, and more specifically, relates to a machine cover and a cleaning machine. Background Technology

[0002] Cleaning machines are typically used to clean tableware, drinking containers (such as water cups and baby bottles), and other items that require cleaning. A cleaning machine consists of a body and a cover, which together form a cleaning chamber. A spray device in the cleaning chamber can spray water onto the items to be cleaned.

[0003] Sprayers typically spray water upwards to clean items placed in the cleaning chamber. After the water sprays onto the top panel of the machine cover, it flows along the inner side of the top panel to the side panels, and then flows downwards along the side panels. Water is prone to leaking from the lower end of the side panels, affecting the user experience. Summary of the Invention

[0004] The purpose of this application is to provide a machine cover and a cleaning machine to improve the user experience.

[0005] To achieve the above objectives, the technical solution adopted in this application is as follows: In a first aspect, this application provides a machine cover for a cleaning machine. The cleaning machine includes a machine body and a spraying device. The machine cover is adapted to be connected to the machine body and is used to enclose the machine body to form a cleaning chamber. The spraying device is disposed in the cleaning chamber. The machine cover includes a top plate, side plates, and a baffle. The inner side of the top plate is provided with a spraying area for facing the spraying device. The side plates are connected to the edge of the top plate. The baffle is located between the side plates and the spraying area and is connected to the inner side of the top plate. The baffle extends circumferentially along the top plate.

[0006] Through the above technical solution, the machine cover provided in this application has a spray area on the inner side of the top plate. When the machine cover is used for a cleaning machine, the spray device will spray water in the direction towards the spray area to clean the items to be cleaned. A portion of the water from the spray device will be sprayed into the spray area and then flow along the inner side of the top plate towards the side plate, forming a transverse water flow. After reaching the side plate, the transverse water flow will flow downward along the inner side of the side plate, and is prone to leakage from the lower end of the side plate.

[0007] The hood provided in this application is also equipped with a baffle, which is located between the side plate and the spray area. The baffle can block the lateral water flow from the spray area toward the side plate, and can make the lateral water flow downward from the inner side of the baffle, so that the lateral water flow falls down in advance, thereby blocking the water flowing toward the side plate, which helps to prevent water from leaking from the lower end of the side plate, and thus helps to improve the user experience.

[0008] Therefore, the cover provided in this application is useful for preventing cleaning water from leaking from the lower end of the side panel after being used in the cleaning machine, which helps to improve the user experience.

[0009] In some embodiments, the distance between at least a portion of the spoiler's surface facing the side plate and the side plate gradually increases in the direction away from the top plate, and / or the distance between at least a portion of the spoiler's surface away from the side plate and the side plate gradually decreases in the direction away from the top plate.

[0010] In this way, the surface of the spoiler facing the side plate can act as a guide, allowing water splashed onto this surface to flow downwards. Similarly, the surface of the spoiler away from the side plate can also act as a guide, allowing water splashed onto this surface to flow downwards.

[0011] In some embodiments, the side plate includes a plurality of sub-plates connected sequentially along the circumference of the top plate, and the spoiler includes a first spoiler section and a second spoiler section arranged along the circumference of the top plate. At least one sub-plate has a first turbulence section on its inner side, and a second turbulence section is provided on the inner side of the connection between every two adjacent sub-plates, and the second turbulence section extends from the inner side of one of the two adjacent sub-plates to the inner side of the other sub-plate.

[0012] The first turbulence section can block the lateral water flow from the spray area toward at least one side plate, thereby blocking the lateral water flow toward the side plate and helping to prevent water leakage from the lower end of the side plate.

[0013] Understandably, the junction of two adjacent sub-plates has a corner, making the lower end more prone to leakage. The cover provided in this application has a second turbulence section on the inner side of the junction of every two adjacent sub-plates, and the second turbulence section extends from the inner side of one sub-plate to the inner side of the other sub-plate. In this way, the second turbulence section can block the lateral water flow to the junction of the two adjacent sub-plates, thereby helping to prevent water leakage from the lower end of the junction of the two adjacent sub-plates.

[0014] In some implementations, a chamfered structure is provided at the connection between every two adjacent sub-plates.

[0015] This allows for a smoother transition between two adjacent sub-plates via a chamfered structure, reducing the bending angle and improving the sealing at the connection between the hood and the body. This, in turn, helps prevent water leakage from the bottom of the side plate.

[0016] In some embodiments, the side panel includes multiple sub-panels connected sequentially along the circumference of the top panel, with a chamfered structure at the joint between every two adjacent sub-panels. This facilitates a smooth transition between two adjacent sub-panels through the chamfered structure, reducing the bending angle and thus improving the sealing at the connection between the hood and the body, thereby preventing water leakage from the lower end of the side panel.

[0017] In some embodiments, the hood provided in this application further includes a baffle plate and a vent cover with ventilation holes. The top plate has a mounting hole, the vent cover is installed in the mounting hole, the baffle plate is connected below the top plate and the vent cover and covers the mounting hole, and an exhaust port communicating with the mounting hole is provided between the baffle plate and the top plate.

[0018] With the above technical solution, when the hood provided by this application is used in a cleaning machine, when the cleaning machine dries or steam cleans the items to be cleaned in the cleaning chamber, the steam can enter the mounting hole from the exhaust port and then be discharged through the vent hole. The baffle can at least block the cleaning water to a certain extent, which helps to prevent the cleaning water from splashing out from the vent hole.

[0019] In some embodiments, the vent is located on one side of the mounting hole in a first direction, which is perpendicular to the thickness direction of the top plate.

[0020] Through the above technical solution, the baffle can block the steam and hot air blowing towards the baffle along the thickness direction of the top plate, so that the steam and hot air avoid the baffle in the first direction, enter the mounting hole from the exhaust port, and then exit from the vent hole.

[0021] In some embodiments, the vent cover has a water-blocking box on the side facing the baffle plate, the water-blocking box forms an exhaust channel, the outlet of the exhaust channel is connected to the vent hole, and the inlet of the exhaust channel faces away from the exhaust port in a first direction.

[0022] Through the above technical solution, the water-blocking box can work together with the baffle plate to achieve a water-blocking effect, providing double water blocking. When cleaning water enters the mounting hole from the vent, the water-blocking box can prevent water from entering the mounting hole from the vent. Furthermore, the steam entering the mounting hole from the vent can enter the exhaust channel from the inlet under the influence of the pressure difference (the air pressure inside the cleaning chamber is higher than the external air pressure), and then be discharged from the vent.

[0023] In some embodiments, the vent cover is provided with multiple vent holes, which are arranged sequentially at intervals along a first direction. The side of the vent cover facing the baffle is provided with multiple water-blocking boxes, which are arranged one-to-one with the multiple vent holes. The water baffle has an exhaust channel and a vent hole connected to the exhaust channel. The outlet of the exhaust channel is connected to the corresponding vent hole. The vent hole is located at the inlet of the exhaust channel. The vent hole of the water baffle closest to the exhaust port faces away from the exhaust port along the first direction, while the vent holes of the other water baffles face the exhaust port along the first direction.

[0024] Through the above technical solution, the water baffle box closest to the vent can block water from entering the mounting hole from the vent, which helps to prevent water from entering the mounting hole from the vent and then entering the interior of the water baffle box (venting channel). When water entering the mounting hole from the vent reaches the connecting wall, it can be reflected, and the other water baffle boxes can block the water reflected by the connecting wall, which helps to prevent water from entering the mounting hole from the vent and then entering the interior of the water baffle box (venting channel).

[0025] In some embodiments, the body includes a base and an upright plate connected to the base. The side plate includes a plurality of sub-plates connected in sequence along the circumference of the top plate. One of the sub-plates is used to connect to the upright plate. The sub-plate used to connect to the upright plate is the first sub-plate. The first sub-plate is provided with a notch. The notch penetrates the first sub-plate along a first direction and penetrates the end of the first sub-plate away from the top plate (the lower end). The first direction is the thickness direction of the first sub-plate. The outer side of the first sub-plate is provided with a flow guiding groove, which extends circumferentially along the notch.

[0026] Understandably, when the cover and body are connected, water in the cleaning chamber can easily enter the gap between the first sub-plate and the upright plate of the body through the notch, causing leakage. The outer side of the first sub-plate is provided with a guide groove extending circumferentially along the notch, which allows water entering the gap between the first sub-plate and the upright plate of the body through the notch to enter the guide groove, thereby helping to prevent leakage between the first sub-plate and the upright plate of the body.

[0027] In some embodiments, the outer surface of the first sub-plate is adapted to fit against the upright plate, which is used to seal the side of the flow guide groove facing the upright plate, so that water in the flow guide groove is not easily leaked outward from the gap between the first sub-plate and the upright plate.

[0028] In some embodiments, the first sub-plate is provided with a first water-blocking rib, which protrudes from the outer side of the first sub-plate along a first direction; the first water-blocking rib extends circumferentially along the notch and is located on the inner circumferential side of the guide groove.

[0029] Through the above technical solution, the first water-blocking rib can work together with the flow-guiding groove to block the cleaning water from entering the gap between the first sub-plate and the vertical plate of the machine body from the gap, thereby helping to prevent the cleaning water from leaking from the gap between the first sub-plate and the vertical plate of the machine body.

[0030] The first water-blocking rib can initially block the cleaning water leaking from the gap, preventing it from entering the gap between the first sub-plate and the upright plate of the machine body. If the leaking cleaning water passes over or bypasses the first water-blocking rib, it enters the guide groove, which can further block the leaking cleaning water, thus helping to prevent water leakage from the gap between the first sub-plate and the upright plate of the machine body.

[0031] In some embodiments, the first sub-plate is provided with two flow guide holes, which are located on both sides of the notch in a second direction, the second direction being perpendicular to the thickness direction of the top plate and the thickness direction of the first sub-plate. The flow guide hole penetrates the first sub-plate and is connected to the flow guide groove, which extends from one flow guide hole to another.

[0032] With the above technical solution, after the machine cover and the machine body are connected, the water that enters the guide groove can return to the cleaning chamber through the guide hole, which helps to prevent water from accumulating in the guide groove, and thus helps to prevent water from leaking from the gap between the first sub-plate and the vertical plate of the machine body.

[0033] In some implementations, the minimum distance between the flow guide groove and the lower end face of the first sub-plate is greater than 0.

[0034] With the above technical solution, the lower end of the first sub-plate does not have a flow guide groove, which can make the thickness of the lower end of the first sub-plate uniform, which helps to avoid deformation and warping of the lower end of the first sub-plate.

[0035] In some embodiments, the first sub-plate is provided with a second water-blocking rib, which protrudes from the outer side of the first sub-plate along a first direction, the first direction being the thickness direction of the first sub-plate; the second water-blocking rib extends circumferentially along the notch and is located on the outer periphery of the guide groove, and the second water-blocking rib is adapted to abut against the upright plate.

[0036] Through the above technical solution, the second water-blocking rib, together with the first water-blocking rib and the guide groove, can prevent cleaning water from entering the gap between the first sub-plate and the vertical plate of the machine body through the notch, thereby helping to prevent cleaning water from leaking out from the gap between the first sub-plate and the vertical plate of the machine body. Furthermore, the second water-blocking rib is adapted to abut against the vertical plate, thus forming a seal between the second water-blocking rib and the vertical plate, further preventing cleaning water from leaking outward from the gap between the first sub-plate and the vertical plate of the machine body.

[0037] The first water-blocking rib initially prevents cleaning water from leaking through the opening, thus blocking it from entering the gap between the first sub-plate and the upright plate of the machine body. If the leaking cleaning water bypasses or circumvents the first water-blocking rib, it enters the guide groove, which further blocks the leaking water, thereby preventing water leakage from the gap between the first sub-plate and the upright plate of the machine body. If the cleaning water bypasses or circumvents the guide groove, the second water-blocking rib prevents water in the gap between the first sub-plate and the upright plate of the machine body from leaking outwards.

[0038] In some embodiments, the body includes a base, the lower end of a side plate is used to connect to the base, and the base is provided with a first step; The cover includes a first overlapping portion and an extension located on the side of the first overlapping portion facing the base. The first overlapping portion overlaps with a first step, and the extension is located on the inner circumference of the first step. The outer peripheral surface of the extension is used to form a reflux cavity between itself and the inner wall surface of the base, and the lower end of the reflux cavity is provided with an opening.

[0039] Through the above technical solution, the cover provided in this application can overlap with the first step of the base via the first overlapping part. The overlap between the first overlapping part and the first step can form a flow-blocking structure, which helps to prevent water leakage from the overlap between the first overlapping part and the first step. In addition, the cover has an extension on the side facing the base. After the cover is connected to the body, the extension can increase the path of water to the overlap between the first overlapping part and the first step, at least to a certain extent blocking water from reaching the overlap between the first overlapping part and the first step, thereby helping to prevent water leakage from the overlap between the first overlapping part and the first step. Furthermore, the outer peripheral surface of the extension forms a return cavity with the inner wall surface of the base. The lower end of the return cavity has an opening. After the cover is connected to the body, water enters the return cavity before reaching the overlap between the first overlapping part and the first step, and can flow back downward from the return cavity and back into the cleaning cavity from the opening. This helps to prevent water from remaining in the gap between the cover and the base, thereby helping to prevent water leakage from the overlap between the first overlapping part and the first step.

[0040] In some embodiments, the outer peripheral surface of the extension is provided with a reflux groove, and a reflux cavity is formed between the groove wall of the reflux groove and the inner wall surface of the base. The reflux groove is connected to the opening.

[0041] With the above technical solution, the reflux groove is set on the outer peripheral surface of the extension. This way, when the water in the reflux chamber flows back, the water flow is closer to the extension, which is conducive to the reflux water flow entering the cleaning chamber.

[0042] In some embodiments, the base is provided with a second step, which is located below and on the inner periphery of the first step, and the extension is provided with a second overlapping part that overlaps the second step.

[0043] Through the above technical solution, based on the flow-blocking structure formed at the joint between the first overlapping part and the first step, another flow-blocking structure can be formed at the joint between the second overlapping part and the second step. This can achieve a double flow-blocking effect, which helps to prevent water from leaking from the connection between the cover and the base.

[0044] In some embodiments, the reflux groove is located between the first overlap and the second overlap, the first overlap is in contact with the first step, and the second overlap is in clearance fit with the second step.

[0045] In this way, water that has crossed the second overlap can flow back to the second overlap from the return groove before reaching the first overlap, and can also flow back into the cleaning chamber from the gap between the second overlap and the second step, thereby helping to prevent water from leaking at the overlap between the first overlap and the first step.

[0046] In some embodiments, the distance between at least a portion of the wall of the return groove and the inner circumferential surface of the extension gradually decreases along the direction from the first overlap to the extension.

[0047] With the above technical solution, the water in the return groove can flow along the groove wall to the lower end of the extension. In this way, when the water in the return cavity returns, the water flow is closer to the extension, which is conducive to the return water flow entering the cleaning chamber.

[0048] In some embodiments, the body also includes a vertical plate for connecting the base, and the side plate includes a plurality of sub-plates connected in sequence along the circumference of the top plate, one of which is used to connect the vertical plate, the sub-plate used to connect the vertical plate is the first sub-plate, and the sub-plate not connected to the vertical plate is the second sub-plate. The first overlapping portion and the extension portion are disposed on the second sub-plate and extend circumferentially to the first sub-plate along the top plate. This helps to improve the flow resistance effect of the first overlapping portion and the first step, and can help prevent water from leaking from the connection between the second sub-plate and the base.

[0049] In some embodiments, the body includes a base and an upright plate connected to the base, and the side plate includes a plurality of sub-plates connected in sequence along the circumference of the top plate, one of which is used to connect the upright plate, and the sub-plate used to connect the upright plate is the first sub-plate. The outer side of the first sub-plate is provided with a first detection element and a second detection element. The first detection element is used to trigger the first detector installed on the upright plate, and the second detection element is used to trigger the second detector installed on the upright plate.

[0050] Through the above technical solution, the machine cover provided in this application can use the first detection element and the second detection element to trigger the first detector and the second detector installed on the vertical plate respectively. This allows the cleaning machine to perform dual detection, which can improve the detection accuracy and avoid working when the machine cover and the machine body are not installed in place, thereby helping to prevent water leakage from the cleaning machine.

[0051] Secondly, this application provides a cleaning machine, which includes a machine body, a spraying device, and a machine cover as described in any of the above embodiments. The machine cover is connected to the machine body to form a cleaning chamber, and the spraying device is disposed in the cleaning chamber. The cleaning machine provided by this application has the same or similar technical effects as the machine cover of any of the above embodiments, and will not be described in detail here.

[0052] In some embodiments, the cleaning machine includes a controller, a contact sensor, and a Hall sensor mounted on the machine body. The machine cover is provided with a protrusion and a magnet. After the machine cover is connected to the machine body, the protrusion triggers the contact sensor, and the magnet triggers the Hall sensor. The controller is configured as follows: If both the contact sensor and the Hall sensor are triggered simultaneously, it confirms that the hood and body are installed in place. If at least one of the contact sensor and Hall sensor fails to trigger, it is determined that the shroud and body are not properly installed.

[0053] In this way, the cleaning machine provided in this application can perform dual detection through contact sensors and Hall sensors, which can improve detection accuracy and avoid operating when the machine cover and body are not properly installed, thereby helping to prevent water leakage from the cleaning machine.

Detailed Implementation

[0058] To make the technical problems, technical solutions, and beneficial effects to be solved by this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of this application.

[0059] It should be noted that when a component is referred to as being "fixed to" or "set on" another component, it can be directly on or indirectly on that other component. When a component is referred to as being "connected to" another component, it can be directly connected to or indirectly connected to that other component.

[0060] It should be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and 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. Therefore, they should not be construed as limitations on this application.

[0061] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0062] Cleaning machines are typically used to clean tableware, drinking containers (such as water cups and baby bottles), and other items that require cleaning. A cleaning machine consists of a body and a cover, which together form a cleaning chamber. A spray device in the cleaning chamber can spray water onto the items to be cleaned.

[0063] Sprayers typically spray water upwards to clean items placed in the cleaning chamber. After the water sprays onto the top panel of the machine cover, it flows along the inner side of the top panel to the side panels, and then flows downwards along the side panels. Water is prone to leaking from the lower end of the side panels, affecting the user experience.

[0064] To address the aforementioned technical problems, this application provides a machine cover for a cleaning machine. The cleaning machine includes a body and a spray device. The machine cover is adapted to be connected to the body and is used to enclose the body to form a cleaning chamber. The spray device is disposed in the cleaning chamber. The machine cover includes a top plate, side plates, and a baffle plate. The inner side of the top plate is provided with a spray area for facing the spray device. The side plates are connected to the edge of the top plate. The baffle plate is located between the side plates and the spray area and is connected to the inner side of the top plate, extending circumferentially along the top plate.

[0065] Through the above technical solution, the machine cover provided in this application embodiment has a spray area on the inner side of the top plate. When the machine cover is used for a cleaning machine, the spray device will spray water in the direction towards the spray area to clean the items to be cleaned. A portion of the water from the spray device will be sprayed into the spray area and then flow along the inner side of the top plate toward the side plate, forming a transverse water flow. After reaching the side plate, the transverse water flow will flow downward along the inner side of the side plate, and is prone to leakage from the lower end of the side plate.

[0066] The hood provided in this application embodiment is also provided with a baffle plate, which is located between the side plate and the spray area. The baffle plate can block the lateral water flow from the spray area toward the side plate, and can make the lateral water flow downward from the inner side of the baffle plate, so that the lateral water flow falls down in advance, thereby blocking the water flowing toward the side plate, which helps to prevent water from leaking from the lower end of the side plate, and thus helps to improve the user experience.

[0067] Therefore, the machine cover provided in this application embodiment is used to prevent cleaning water from leaking from the lower end of the side panel after the machine is used, which helps to improve the user experience.

[0068] The cleaning machine provided in the embodiments of this application will be described below with reference to the accompanying drawings.

[0069] Please see Figure 1 and Figure 2 The cleaning machine 1000 provided in this application embodiment includes a body 200 and a cover 100. The cover 100 and the body 200 are connected and enclosed to form the cleaning machine 1000. The cleaning chamber 1001 can hold items to be cleaned. The items to be cleaned can be tableware, drinking containers (such as water cups, baby bottles), etc.

[0070] The cleaning machine 1000 provided in this application embodiment also includes a water pump (not shown in the figure) and a spray device (not shown in the figure). The water pump can be installed in the machine body 200, and the spray device can be installed in the cleaning chamber 1001. The water outlet of the water pump can be connected to the water inlet of the spray device, so that the water pump can supply water to the spray device, and the spray device can spray water toward the items to be cleaned to clean the items.

[0071] The water pump's inlet is connected to a water source, which can be a water tank installed on the machine body 200, or an external water storage container or a tap.

[0072] Please see Figure 3 and combined Figure 1 and Figure 2 The machine cover 100 provided in this application embodiment can be provided with a handhold 30, which makes it convenient for users to pick up the machine cover 100 and thus convenient to pick up the items to be cleaned.

[0073] The machine cover 100 provided in this application embodiment includes a top plate 10, and a hand-held part 30 can be disposed on the top plate 10, and a hand-held groove 301 can be formed between the hand-held part 301 and the top plate 10, which facilitates the entry of a person's hand.

[0074] At least a portion of the cover 100 provided in this application embodiment can be made of transparent material, which makes it easy to view the cleaning status of the items to be cleaned through the cover 100, which helps to increase user trust and thus improve the user experience.

[0075] Please see Figure 4 and Figure 5 The machine cover 100 provided in this embodiment includes a side plate 20, which is connected to the edge of the top plate 10. The inner side of the top plate 10 is provided with a spray area, which faces the spraying device. The machine cover 100 provided in this embodiment has a spray area on the inner side of the top plate 10. The item to be cleaned in the cleaning chamber 1001 corresponds to the spray area; that is, the orthographic projection of the item to be cleaned onto the inner side of the top plate 10 is located within the spray area. It should be noted that the inner side of the top plate 10 is the surface of the top plate 10 facing the cleaning chamber 1001, and the inner side of the side plate 20 in the following text is also the surface of the side plate 20 facing the cleaning chamber 1001.

[0076] When the cleaning machine 1000 cleans the items to be cleaned, the spray device sprays water in the direction towards the spray area to clean the items. A portion of the water from the spray device is sprayed into the spray area and then flows along the inner side of the top plate 10 toward the side plate 20, forming a transverse water flow. After reaching the side plate 20, the transverse water flow flows downward along the inner side of the side plate 20, which can easily leak from the lower end of the side plate 20.

[0077] It should be noted that the body 200 includes a base 210 and a vertical plate 220 connected to the base 210. The cover 100 is located above the base 210, and the lower end of the cover 100 is connected to the base 210.

[0078] Please continue reading. Figure 4 and Figure 5 The hood 100 provided in this application embodiment also includes a spoiler 40, which is located between the side plate 20 and the spray area. The spoiler 40 is connected to the inner side of the top plate 10 and extends circumferentially along the top plate 10.

[0079] Through the above technical solution, the baffle 40 can block the lateral water flow from the spray area toward the side plate 20, and can make the lateral water flow downward from the inner side of the baffle 40, so that the lateral water flow falls down in advance, thereby blocking the water flowing toward the side plate 20, which helps to prevent water from leaking from the lower end of the side plate 20, and thus helps to improve the user experience.

[0080] Therefore, the cover 100 provided in this application embodiment is used in the cleaning machine 1000 to help prevent cleaning water from leaking from the lower end of the side plate 20, which helps to improve the user experience.

[0081] In some embodiments, the distance between at least a portion of the surface of the spoiler 40 facing the side plate 20 and the side plate 20 gradually increases in the direction away from the top plate 10, and / or the distance between at least a portion of the surface of the spoiler 40 away from the side plate 20 and the side plate 20 gradually decreases in the direction away from the top plate 10.

[0082] Optionally, the distance between at least a portion of the surface of the spoiler 40 facing the side plate 20 and the side plate 20 gradually increases in the direction away from the top plate 10. In this way, the surface of the spoiler 40 facing the side plate 20 can have a guiding effect, and water splashed onto the surface of the spoiler 40 facing the side plate 20 can easily flow downward from the spoiler 40.

[0083] Optionally, the distance between at least a portion of the surface of the spoiler 40 away from the side plate 20 and the side plate 20 gradually decreases in the direction away from the top plate 10. In this way, the surface of the spoiler 40 away from the side plate 20 can have a guiding effect, and water splashed onto the surface of the spoiler 40 away from the side plate 20 can easily flow downward from the spoiler 40.

[0084] Optionally, the distance between at least a portion of the surface of the spoiler 40 facing the side plate 20 and the side plate 20 gradually increases in the direction away from the top plate 10, and the distance between at least a portion of the surface of the spoiler 40 away from the side plate 20 and the side plate 20 gradually decreases in the direction away from the top plate 10. In this way, both the surface of the spoiler 40 facing the side plate 20 and the surface away from the side plate 20 can have a guiding effect, and water splashed onto the surface of the spoiler 40 facing the side plate 20 can easily flow downward from the spoiler 40.

[0085] Please continue reading. Figure 4 and Figure 5 In some embodiments, the side plate 20 includes a plurality of sub-plates connected sequentially along the circumference of the top plate 10, and the spoiler 40 includes a first spoiler section 41 and a second spoiler section 42 arranged along the circumference of the top plate 10. The plurality of sub-plates are connected sequentially to form a cavity, and the number of sub-plates is 3, 4, 5, 6, 7, 8, etc.

[0086] One of the sub-boards is used to connect to the upright board 220. The sub-board used to connect to the upright board 220 is the first sub-board 21, and the sub-board not connected to the upright board 220 is the second sub-board 22.

[0087] At least one sub-plate has a first turbulence section 41 on its inner side, and a second turbulence section 42 is provided on the inner side of the connection between every two adjacent sub-plates, and the second turbulence section 42 extends from the inner side of one of the two adjacent sub-plates to the inner side of the other sub-plate.

[0088] The first turbulence section 41 can block the lateral water flow from the spray area toward at least one side plate 20, thereby blocking the lateral water flow toward the side plate 20 and helping to prevent water leakage from the lower end of the side plate 20.

[0089] It is understandable that there is a corner at the connection between two adjacent sub-plates, making the lower end more prone to leakage. The cover 100 provided in this application embodiment has a second turbulence section 42 on the inner side of the connection between two adjacent sub-plates, and the second turbulence section 42 extends from the inner side of one sub-plate to the inner side of the other sub-plate. In this way, the second turbulence section 42 can block the lateral water flow to the connection between two adjacent sub-plates, thereby helping to prevent water leakage from the lower end of the connection between two adjacent sub-plates.

[0090] Furthermore, a chamfered structure can be provided at the connection between every two adjacent sub-plates. This facilitates a smooth transition between two adjacent sub-plates through the chamfered structure, reducing the bending angle and thus improving the sealing performance at the connection between the shroud 100 and the body 200, thereby preventing water leakage from the lower end of the side plate 20. Moreover, the chamfered structure increases the area at the connection between two adjacent sub-plates, helping to prevent water from concentrating at that connection point.

[0091] In some embodiments, the side panel 20 includes a plurality of sub-panels connected sequentially along the circumference of the top panel 10, with a chamfered structure at the joint of every two adjacent sub-panels. This facilitates a smooth transition between two adjacent sub-panels through the chamfered structure, reducing the bending angle and thus improving the sealing at the joint between the hood 100 and the body 200, thereby preventing water leakage from the lower end of the side panel 20. Furthermore, the chamfered structure increases the area at the joint of two adjacent sub-panels, helping to prevent water from concentrating at the joint.

[0092] Please continue reading. Figure 3 and Figure 4 In some embodiments, the hood 100 includes a vent cover 60 and a baffle plate 70. The top plate 10 is provided with a mounting hole 101. The vent cover 60 is detachably mounted in the mounting hole 101 and has a vent hole 601 communicating with the mounting hole 101. The baffle plate 70 is disposed below the top plate 10 and the vent cover 60 and blocks the mounting hole 101. An exhaust port 102 communicating with the mounting hole 101 is provided between the baffle plate 70 and the top plate 10.

[0093] With the above technical solution, when the cleaning machine 1000 performs hot air drying or steam cleaning on the items to be cleaned in the cleaning chamber 1001, the steam and hot air can enter the mounting hole 101 from the exhaust port 102 and then be discharged from the vent 601. The baffle plate 70 can prevent the steam and hot air from directly entering the vent 601. This can change the flow direction of the steam and hot air, increase the path length of the steam and hot air, and help reduce the temperature of the steam and hot air, thereby helping to avoid scalding the user and improving the user experience.

[0094] Furthermore, the baffle 70 can at least partially block the cleaning water, which helps to prevent the cleaning water from splashing out of the vent 601, thereby improving the user experience.

[0095] In addition, the vent cover 60 is detachably installed in the mounting hole 101, and the vent cover 60 can be removed for cleaning, which makes it easier to clean the residue at the vent hole 601, thereby improving the user experience.

[0096] Therefore, the cleaning machine 1000 provided in this application embodiment can improve the user experience.

[0097] Please continue reading. Figure 2 , Figure 3 and Figure 4 The machine cover 100 provided in this application embodiment also includes a side plate 20, which is connected to the edge of the top plate 10. The machine body 200 includes a base 210 and a vertical plate 220 connected to the base 210. The machine cover 100 is located above the base 210, and the lower end of the machine cover 100 is connected to the base 210.

[0098] The side plate 20 includes multiple sub-plates connected sequentially along the circumference of the top plate 10. One sub-plate is used to connect to the vertical plate 220. The sub-plate used to connect to the vertical plate 220 is the first sub-plate 21, and the sub-plate not connected to the vertical plate 220 is the second sub-plate 22. The first sub-plate 21 has a notch 2101 that penetrates the first sub-plate 21 along a first direction X and penetrates the end of the first sub-plate 21 away from the top plate 10 (the lower end). The end of the first sub-plate 21 connected to the top plate 10 is the upper end. The first direction X is the thickness direction of the first sub-plate 21. The vertical plate 220 has a boss on the side facing the cleaning chamber 1001. The boss is embedded in the notch 2101, so that the boss can position the cover 100. The lower end face of the second sub-plate 22 overlaps with the base 210. The inner side of the base 210 has a limiting plate 230. There is a gap between the limiting plate 230 and the base 210, and the lower end of the second sub-plate 22 is stuck in the gap.

[0099] Please see Figure 4 and Figure 5In some embodiments, the periphery of the baffle 70 is provided with a connecting wall 71 extending toward and connecting to the top plate 10; wherein, the exhaust port 102 is disposed on the connecting wall 71, and / or, the exhaust port 102 and the connecting wall 71 are arranged along the periphery of the baffle 70.

[0100] Optionally, the exhaust port 102 is located on the connecting wall 71.

[0101] Optionally, the exhaust port 102 and the connecting wall 71 are arranged circumferentially along the baffle plate 70.

[0102] Optionally, the exhaust port 102 is disposed on the connecting wall 71, and the exhaust port 102 and the connecting wall 71 are arranged along the circumference of the baffle plate 70.

[0103] Understandably, the baffle 70 can at least partially block the water used for cleaning from entering the mounting hole 101, and allows steam and hot air to bypass the baffle 70 and enter the mounting hole 101 through the exhaust port 102, and then exit through the vent 601. This allows the steam and hot air to exit smoothly and changes the flow direction of the steam and hot air, increasing the path length of the steam and hot air, which helps to reduce the temperature of the steam and hot air, and thus helps to avoid scalding the user.

[0104] Please see Figure 4 and Figure 5 In some embodiments, the exhaust port 102 is disposed on one side of the mounting hole 101 in a first direction X, which is perpendicular to the thickness direction Z of the top plate 10. In this way, the baffle plate 70 can block the steam and hot air blowing toward the baffle plate 70 along the thickness direction Z of the top plate 10, so that the steam and hot air bypass the baffle plate 70 along the first direction X, enter the mounting hole 101 from the exhaust port 102, and then exit from the vent hole 601.

[0105] Please see Figure 6 , Figure 7 and Figure 8 In some embodiments, the vent cover 60 is provided with a water-blocking box 61 on the side facing the baffle plate 70. The water-blocking box 61 forms an exhaust channel 6101. The outlet of the exhaust channel 6101 is connected to the vent hole 601, and the inlet of the exhaust channel 6101 is opposite to the exhaust port 102 along the first direction X.

[0106] Through the above technical solution, the water-blocking box 61 and the baffle plate 70 can work together to block water, providing a double water-blocking effect. When cleaning water enters the mounting hole 101 from the exhaust port 102, the water-blocking box 61 can block the water from entering the mounting hole 101 from the exhaust port 102. Furthermore, the steam and hot air entering the mounting hole 101 from the exhaust port 102 can enter the exhaust channel 6101 from the inlet under the action of the air pressure difference (the air pressure inside the cleaning chamber 1001 is higher than the external air pressure), and then be discharged from the vent 601.

[0107] Please continue reading. Figure 6 , Figure 7 and Figure 8 In some embodiments, the vent cover 60 is provided with a plurality of vent holes 601, which are arranged sequentially at intervals along the first direction X. The vent cover 60 is provided with a plurality of water-blocking boxes 61 on the side facing the baffle plate 70, and the plurality of water-blocking boxes 61 are arranged in a one-to-one correspondence with the plurality of vent holes 601.

[0108] The water-blocking box 61 has an exhaust channel 6101 and a vent 6102 connected to the exhaust channel 6101. The outlet of the exhaust channel 6101 is connected to the corresponding vent 601. The vent 6102 is located at the inlet of the exhaust channel 6101. The vent 6102 of the water-blocking box 61 closest to the exhaust port 102 faces away from the exhaust port 102 along the first direction X. The vents 6102 of the other water-blocking boxes 61 face the exhaust port 102 along the first direction X.

[0109] Understandably, the water-blocking box 61 closest to the vent 102 can block water from entering the mounting hole 101 from the vent 102, thus preventing water from entering the mounting hole 101 from the vent 102 from entering the interior of the water-blocking box 61 (venting channel 6101). When water entering the mounting hole 101 from the vent 102 reaches the connecting wall 71, it can be reflected. The remaining water-blocking boxes 61 can block the water reflected by the connecting wall 71, thus preventing water from entering the mounting hole 101 from the vent 102 from entering the interior of the water-blocking box 61 (venting channel 6101).

[0110] In some embodiments, the outer peripheral side of the vent cover 60 abuts against the wall of the mounting hole 101.

[0111] As an example, the outer periphery of the vent cover 60 is interference-fitted with the wall of the mounting hole 101.

[0112] As an example, a sealing gasket (not shown in the figure) is provided between the outer peripheral side of the vent cover 60 and the hole wall of the mounting hole 101. The sealing gasket abuts against the outer peripheral side of the vent cover 60 and the hole wall of the mounting hole 101. That is, the outer peripheral side of the vent cover 60 abuts against the hole wall of the mounting hole 101 through the sealing gasket.

[0113] In this way, a resisting force can be formed between the vent cover 60 and the wall of the mounting hole 101, and a static friction force can be formed between the vent cover 60 and the wall of the mounting hole 101. This is beneficial for the vent cover 60 to be stably installed in the mounting hole 101. Furthermore, when an external force is applied to the vent cover 60, the friction force between the vent cover 60 and the wall of the mounting hole 101 can be overcome, thereby allowing the vent cover 60 to be removed.

[0114] Please continue reading. Figure 6 , Figure 7 and Figure 8 In some embodiments, the top plate 10 and / or the shield 70 are detachably connected to the vent cover 60.

[0115] Optionally, the top plate 10 and the vent cover 60 are detachably connected.

[0116] Optionally, the shield 70 and the vent cover 60 are detachably connected.

[0117] Optionally, the top plate 10 and the baffle plate 70 are detachably connected to the vent cover 60.

[0118] In this way, the vent cover 60 can be detachably connected to the top plate 10 or the shield 70, or it can be detachably connected to both the top plate 10 and the shield 70 respectively. The connection objects of the vent cover 60 (top plate 10 and / or shield 70) can be selected according to product requirements, thereby improving applicability.

[0119] Please see Figure 9 and combined Figure 4 In some examples, the vent cover 60 is provided with a buckle 62, and the baffle 70 is provided with a snap-fit ​​hole 701; The vent cover 60 is engaged with the exhaust port 102 via a snap fastener 62, and / or the vent cover 60 is engaged with the snap fastener 62 via a snap fastener 701.

[0120] Optionally, the vent cover 60 is snapped into the exhaust port 102 by a snap fastener 62.

[0121] Optionally, the vent cover 60 is snapped into the snap hole 701 by a snap fastener 62.

[0122] Optionally, the vent cover 60 is engaged with the exhaust port 102 via a snap fastener 62, and is also engaged with the engagement hole 701 via the snap fastener 62. For example, the snap fastener 62 includes a first snap fastener 621 and a second snap fastener 622, the first snap fastener 621 being engaged with the exhaust port 102, and the second snap fastener 622 being engaged with the engagement hole 701.

[0123] In this way, the vent cover 60 can be snapped onto the top plate 10 and / or the baffle plate 70 via the buckle 62, which can improve the stability of the vent cover 60.

[0124] Of course, in other examples, the vent cover 60 can be connected to the top plate 10 and / or the shield 70 by means of bolts or other fasteners.

[0125] Please see Figure 9 In some embodiments, the top plate 10 and the shield 70 are integrally formed, which facilitates the manufacture of the top plate 10 and the shield 70. For example, the top plate 10 and the shield 70 can be manufactured by injection molding, pressurization, or other methods.

[0126] In other examples, the top plate 10 is detachably connected to the shield 70, which facilitates the removal of the shield 70. For example, the top plate 10 and the shield 70 are snap-fitted together or connected by a threaded fastener.

[0127] Please see Figure 10 and Figure 11 and combined Figure 1 and Figure 2 In some embodiments, the machine body 200 includes a base 210, with a first step 240 at one end of the base 210 facing the machine cover 100. The machine cover 100 includes a first overlapping portion 221, which overlaps with the first step 240, and an extension 224 is located on the inner circumferential side of the first step 240. In this way, the cleaning machine 1000 provided in this application embodiment can overlap the first overlapping portion 221 of the machine cover 100 with the first step 240 of the base 210. The overlap between the first overlapping portion 221 and the first step 240 can form a flow-blocking structure, which helps to prevent water leakage from the overlap between the first overlapping portion 221 and the first step 240.

[0128] In addition, the cover 100 also includes an extension 224 located on the side of the first overlapping portion 221 facing the base 210. A reflux cavity 1002 is formed between the outer peripheral surface of the extension 224 and the inner wall surface of the base 210. An opening 10021 is provided at the lower end of the reflux cavity 1002.

[0129] In this way, the extension 224 can increase the path of water to the joint between the first overlap 221 and the first step 240, at least to a certain extent blocking water from reaching the joint between the first overlap 221 and the first step 240, thereby helping to prevent water from leaking from the joint between the first overlap 221 and the first step 240. Furthermore, a return cavity 1002 is formed between the outer peripheral surface of the extension 224 and the inner wall surface of the base 210. The lower end of the return cavity 1002 has an opening 10021. Before reaching the joint between the first overlap 221 and the first step 240, water first enters the return cavity 1002 and can flow back downwards from the return cavity 1002, and then back into the cleaning cavity 1001 from the opening 10021. This helps to prevent water from remaining in the gap between the cover 100 and the base 210, thereby helping to prevent water from leaking from the joint between the first overlap 221 and the first step 240.

[0130] Therefore, the machine cover 100 provided in this application embodiment is used in the cleaning machine 1000 to help prevent cleaning water from leaking from the overlap between the first overlap 221 and the first step 240, which helps to improve the user experience.

[0131] Please see Figure 11 and Figure 12 Optionally, the upper end of the reflux chamber 1002 is closed, which helps to prevent water in the reflux chamber 1002 from reaching the joint between the first overlap 221 and the first step 240, thereby helping to prevent water from leaking from the joint between the first overlap 221 and the first step 240.

[0132] Optionally, the first step 240 includes a first facade 242 and a first tread 241, and the first overlapping part 221 includes a first overlapping surface 2211 and a second overlapping surface 2212. The first overlapping surface 2211 is used to overlap with the first tread 241, and the second overlapping surface 2212 overlaps with the first facade 242.

[0133] The second overlapping surface 2212 fits into the first vertical surface 242 after overlapping, which can seal the upper end of the return cavity 1002.

[0134] Please see Figure 11 and Figure 12 In some embodiments, the outer peripheral surface of the extension 224 is provided with a reflux groove 223, and a reflux cavity 1002 is formed between the groove wall of the reflux groove 223 and the inner wall of the base 210. The reflux groove 223 is connected to the opening 10021.

[0135] It is understandable that the return groove 223 is provided on the outer peripheral surface of the extension 224, so that when the water in the return cavity 1002 returns, the water flow is closer to the extension 224, which is conducive to the return water flow entering the cleaning cavity 1001.

[0136] Optionally, at least a portion of the return groove 223 is located on the inner circumferential side of the first overlap 221. In this way, the cleaning water can more easily fall back into the return groove 223 before reaching the first overlap 221, and thus enter the return cavity 1002 and flow back into the cleaning cavity 1001.

[0137] Please continue reading. Figure 11 and Figure 12 In some embodiments, the base 210 is provided with a second step 250, which is located below and on the inner periphery of the first step 240, and the extension 224 is provided with a second overlapping portion 222 that overlaps the second step 250. The second step 250 is further away from the top plate 10 of the cover 100 and closer to the center of the cleaning chamber 1001 than the first step 240.

[0138] Through the above technical solution, based on the flow-blocking structure formed at the joint between the first overlapping part 221 and the first step 240, another flow-blocking structure can be formed at the joint between the second overlapping part 222 and the second step 250. This can achieve a double flow-blocking effect, which helps to prevent water from leaking from the connection between the cover 100 and the base 210.

[0139] Please continue reading. Figure 11 and Figure 12 In some embodiments, the return groove 223 is located between the first overlap 221 and the second overlap 222. In this way, water that has crossed the second overlap 222 can flow back to the second overlap 222 from the return groove 223 before reaching the first overlap 221, thereby helping to prevent water leakage at the overlap between the first overlap 221 and the first step 240.

[0140] In other embodiments, the second overlap 222 is located between the first overlap 221 and the return groove 223. This allows the cleaning water to enter the return chamber 1002 before reaching the overlap between the second overlap 222 and the second step 250, and to flow downwards from the return chamber 1002 and back into the cleaning chamber 1001 from the opening 10021. This helps prevent water from remaining in the gap between the cover 100 and the base 210, thereby preventing water from leaking across the second overlap 222 from the overlap between the first overlap 221 and the first step 240.

[0141] Understandably, even if water crosses the second overlap 222, the flow-blocking structure formed at the overlap of the first overlap 221 and the first step 240 can prevent water from leaking at the overlap of the first overlap 221 and the first step 240.

[0142] Please continue reading. Figure 11 and Figure 12 In some embodiments, the reflux groove 223 is located between the first overlap 221 and the second overlap 222, the first overlap 221 is in contact with the first step 240, and the second overlap 222 is in clearance fit with the second step 250.

[0143] In this way, water that has crossed the second overlap 222 can flow back to the second overlap 222 from the return groove 223 before reaching the first overlap 221, and can also flow back into the cleaning chamber 1001 from the gap between the second overlap 222 and the second step 250, thereby helping to prevent water leakage at the overlap between the first overlap 221 and the first step 240.

[0144] Optionally, the second step 250 includes a second tread surface 251, the first vertical surface 242 of the first step 240 is connected to the second tread surface 251, the lower end surface of the extension 224 forms a second overlapping portion 222 and overlaps with the second tread surface 251, and the groove wall of the return groove 223 is used to form a return cavity 1002 with the first vertical surface 242 and the second tread surface 251.

[0145] Please continue reading. Figure 11 and Figure 12 In some embodiments, along the direction from the first overlap 221 to the extension 224, at least a portion of the groove wall of the return groove 223 is gradually distanced from the inner circumferential surface of the extension 224.

[0146] In this way, the water in the return groove 223 can flow along the groove wall to the lower end of the extension 224, so that when the water in the return cavity 1002 returns, the water flow is closer to the extension 224, which is conducive to the return water flow entering the cleaning cavity 1001.

[0147] In some embodiments, the body 200 further includes a vertical plate 220 connected to the base 210, and the cover 100 includes a top plate 10 and a side plate 20, with the side plate 20 connected to the edge of the top plate 10. The side plate 20 includes a plurality of sub-plates connected sequentially along the circumference of the top plate 10, one of which is used to connect to the vertical plate 220. The sub-plate used to connect to the vertical plate 220 is the first sub-plate 21, and the sub-plate not connected to the vertical plate 220 is the second sub-plate 22.

[0148] The first overlapping portion 221 and the extension portion 224 are disposed on the second sub-plate 22 and extend circumferentially from the top plate 10 to the first sub-plate 21. That is, the first overlapping portion 221, the second overlapping portion 222, and the return groove 223 are disposed on the second sub-plate 22 and extend circumferentially from the top plate 10 to the first sub-plate 21. This helps to improve the flow resistance effect of the first overlapping portion 221 and the first step 240, and can help prevent water from leaking from the connection between the second sub-plate 22 and the base 210.

[0149] In some embodiments, the first step 240 includes a first rib 243 protruding from the outer wall of the base 210, and / or the first overlap 221 includes a second rib 2213 protruding from the outer wall of the cover 100.

[0150] Optionally, the first step 240 includes a first rib 243 protruding from the outer wall of the base 210. In this way, the first rib 243 can increase the contact area between the first step 240 and the first overlapping part 221, thereby improving the overlapping effect of the first step 240 and the first overlapping part 221.

[0151] Optionally, the first overlapping portion 221 includes a second rib 2213 protruding from the outer wall surface of the housing 100. In this way, the second rib 2213 can increase the contact area between the first overlapping portion 221 and the first step 240, thereby improving the overlapping effect between the first step 240 and the first overlapping portion 221.

[0152] Optionally, the first step 240 includes a first rib 243 protruding from the outer wall of the base 210, and the first overlap 221 includes a second rib 2213 protruding from the outer wall of the cover 100.

[0153] Please see Figure 10 and Figure 11 In some embodiments, the body 200 includes a limiting plate 230 located inside the base 210, and the limiting plate 230 and the base 210 together clamp the extension 224, which helps to improve the stability of the connection between the cover 100 and the base 210.

[0154] Please continue reading. Figure 4 and Figure 5 In some embodiments, the first sub-plate 21 is provided with a notch 2101, which penetrates the first sub-plate 21 along a first direction X and penetrates the end of the first sub-plate 21 away from the top plate 10 (lower end). The end of the first sub-plate 21 connected to the top plate 10 is the upper end. The outer surface of the first sub-plate 21 is provided with a guide groove 2103, which extends circumferentially along the notch 2101. The outer surface of the first sub-plate 21 is the surface facing away from the cleaning chamber 1001, that is, the outer surface of the first sub-plate 21 faces the vertical plate 220.

[0155] Understandably, when the cover 100 and the body 200 are connected, the cleaning water in the cleaning chamber 1001 can easily enter the gap between the first sub-plate 21 and the upright plate 220 of the body 200 through the notch 2101, causing water leakage from the gap between the first sub-plate 21 and the upright plate 220 of the body 200. The outer side of the first sub-plate 21 is provided with a guide groove 2103 extending circumferentially along the notch 2101, which allows water entering the gap between the first sub-plate 21 and the upright plate 220 of the body 200 from the notch 2101 to enter the guide groove 2103, thereby helping to prevent water leakage from the gap between the first sub-plate 21 and the upright plate 220 of the body 200.

[0156] Please continue reading. Figure 4 and Figure 5 and combined Figure 1 and Figure 2 In some embodiments, the outer side of the first sub-plate 21 is attached to the upright plate 220, and the upright plate is used to block the side of the guide groove 2103 facing the upright plate 220, so that the water in the guide groove 2103 is not easy to leak outward from the gap between the first sub-plate 21 and the upright plate 220.

[0157] In some embodiments, please refer to Figure 4 and Figure 5 The first sub-plate 21 is provided with a first water-blocking rib 213, which protrudes from the outer side of the first sub-plate 21 along the first direction X, where the first direction X is the thickness direction of the first sub-plate 21. The first water-blocking rib 213 extends circumferentially along the notch 2101 and is located on the inner circumferential side of the guide groove 2103.

[0158] Through the above technical solution, the first water-blocking rib 213 can work together with the flow-guiding groove 2103 to block the cleaning water from entering the gap between the first sub-plate 21 and the upright plate 220 of the body 200 from the gap 2101, thereby helping to prevent the cleaning water from leaking from the gap between the first sub-plate 21 and the upright plate 220 of the body 200.

[0159] The first water-blocking rib 213 can first block the cleaning water leaking from the gap 2101, preventing the cleaning water from entering the gap between the first sub-plate 21 and the upright plate 220 of the body 200. If the leaking cleaning water passes over or bypasses the first water-blocking rib 213, the cleaning water enters the guide groove 2103, which can continue to block the leaking cleaning water, thereby helping to prevent water leakage from the gap between the first sub-plate 21 and the upright plate 220 of the body 200.

[0160] Please see Figure 4 and Figure 5 In some embodiments, the first water-blocking rib 213 includes a first rib segment, a second rib segment, and a third rib segment connected in sequence. The first and third rib segments are located on opposite sides of the notch 2101 in the second direction Y, and the second rib segment is located on the side of the notch 2101 facing the top plate 10. The second direction Y intersects the first direction X and the thickness direction Z of the top plate 10. That is, the first water-blocking rib 213 can extend continuously from one sidewall of the notch 2101, around the top wall, to another sidewall.

[0161] In this way, the first water-blocking rib 213 can prevent the cleaning water from leaking from above the notch 2101 and from the opposite sides in the second direction Y, thereby helping to avoid water leakage from the gap between the first sub-plate 21 and the upright plate 220 of the body 200.

[0162] In some embodiments, at least a portion of the first rib segment and / or at least a portion of the third rib segment has a dimension along the first direction X smaller than the dimension of the second rib segment along the first direction X. This improves the flexibility of the first sub-plate 21, facilitating the installation of the cover 100 and the body 200.

[0163] Optionally, at least a portion of the first stiffener segment has a dimension along the first direction X that is smaller than the dimension of the second stiffener segment along the first direction X.

[0164] Optionally, at least a portion of the third rib segment has a dimension along the first direction X that is smaller than the dimension of the second rib segment along the first direction X.

[0165] Optionally, at least a portion of the first stiffener segment and at least a portion of the third stiffener segment have dimensions along the first direction X smaller than the dimensions of the second stiffener segment along the first direction X.

[0166] In some embodiments, the dimensions of the first rib segment and / or the third rib segment gradually decrease in the direction away from the top plate 10 along the first direction X. This facilitates the injection molding of the cover 100 and allows for easy demolding at the first and third rib segments.

[0167] Optionally, the dimension of the first rib segment along the first direction X gradually decreases in the direction away from the top plate 10.

[0168] Optionally, the dimension of the third rib segment along the first direction X gradually decreases in the direction away from the top plate 10.

[0169] Optionally, the dimensions of the first and third stiffening segments along the first direction X gradually decrease in the direction away from the top plate 10.

[0170] Please see Figure 4 and Figure 5 In some embodiments, the inner side of the first water-blocking rib 213 is aligned with the hole wall of the notch 2101, which can improve the water-blocking effect of the first water-blocking rib 213 and help prevent water from entering the gap between the first sub-plate 21 and the upright plate 220 of the body 200 from the notch 2101.

[0171] Please see Figure 13 and combined Figure 4 In some embodiments, the first sub-plate 21 is provided with two flow guide holes 2104, which are located on both sides of the notch 2101 in the second direction Y, which is perpendicular to the thickness direction Z of the top plate 10 and the thickness direction of the first sub-plate 21. The flow guide holes 2104 penetrate the first sub-plate 21 and communicate with the flow guide groove 2103, which extends from one flow guide hole 2104 to the other flow guide hole 2104.

[0172] Understandably, when the shroud 100 and the body 200 are connected, the water entering the guide groove 2103 can return to the cleaning chamber 1001 through the guide hole 2104, which helps to prevent water from accumulating in the guide groove 2103, and further helps to prevent water from leaking from the gap between the first sub-plate 21 and the upright plate 220 of the body 200.

[0173] In some embodiments, the minimum distance between the flow guide groove 2103 and the lower end surface of the first sub-plate 21 is greater than 0. In this way, the flow guide groove 2103 is not provided at the lower end of the first sub-plate 21, which can make the thickness of the lower end of the first sub-plate 21 uniform and help to avoid deformation or warping of the lower end of the first sub-plate 21.

[0174] In some embodiments, the first sub-plate 21 is provided with a second water-blocking rib 214, the second water-blocking rib 214 protruding from the outer side of the first sub-plate 21 along a first direction X, the first direction X being the thickness direction of the first sub-plate 21; the second water-blocking rib 214 extends circumferentially along the notch 2101 and is located on the outer periphery of the guide groove 2103, the second water-blocking rib 214 abutting against the upright plate 220.

[0175] Through the above technical solution, the second water-blocking rib 214, together with the first water-blocking rib 213 and the guide groove 2103, can prevent cleaning water from entering the gap between the first sub-plate 21 and the upright plate 220 of the body 200 through the notch 2101, thereby helping to prevent cleaning water from leaking out of the gap between the first sub-plate 21 and the upright plate 220 of the body 200. Furthermore, the second water-blocking rib 214 abuts against the upright plate 220, thus forming a seal between the second water-blocking rib 214 and the upright plate 220, which helps to prevent cleaning water in the guide groove 2103 from leaking outward from the gap between the first sub-plate 21 and the upright plate 220 of the body 200.

[0176] The first water-blocking rib 213 can initially block the cleaning water leaking from the notch 2101, preventing it from entering the gap between the first sub-plate 21 and the upright plate 220 of the body 200. If the leaking cleaning water bypasses or bypasses the first water-blocking rib 213, it enters the guide groove 2103, which can further block the leaking cleaning water, thus helping to prevent water leakage from the gap between the first sub-plate 21 and the upright plate 220 of the body 200. If the cleaning water bypasses or bypasses the guide groove 2103, the second water-blocking rib 214 can prevent water in the gap between the first sub-plate 21 and the upright plate 220 of the body 200 from leaking outwards.

[0177] Please see Figure 14 and combined Figure 4 In some embodiments, the machine cover 100 provided in this application embodiment further includes a guide plate 50, which is connected to the side of the top plate 10 facing the cleaning chamber 1001, and a guide protrusion 51 is provided on the side of the guide plate 50 away from the top plate 10.

[0178] In this way, when the cleaning machine 1000 cleans the items to be cleaned in the cleaning chamber 1001, the cleaning liquid splashed onto the guide plate 50 can flow downward along the side of the guide plate 50, and can be collected at the guide protrusion 51 to form a downward-flowing water column, so that the items to be cleaned can be cleaned using this water column, thereby improving the cleaning efficiency.

[0179] Optionally, the deflector 50 has an arc-shaped structure, and the center of the arc of the deflector 50 is located on the side of the deflector 50 facing the center of the top plate 10.

[0180] In this way, the baffle plate 50 can increase the water-blocking area, which helps to increase the amount of cleaning fluid flowing downward from the baffle plate 50. Some of the cleaning fluid splashed on the baffle plate 50 can be reflected towards the center of the top plate 10, which helps the cleaning fluid fall to the center of the cleaning chamber 1001. The items to be cleaned are usually placed in the area close to the center, which helps to increase the amount of cleaning fluid flowing onto the items to be cleaned, thereby improving the cleaning effect.

[0181] Please see Figure 2 and Figure 4 In some embodiments, the outer side of the first sub-plate 21 is provided with a first detection element and a second detection element. The first detection element is used to trigger the first detector installed on the upright plate 220, and the second detection element is used to trigger the second detector installed on the upright plate 220.

[0182] In this way, the machine cover 100 provided in this application embodiment can use the first detection element and the second detection element to trigger the first detector and the second detector installed on the upright plate 220 respectively. This allows the cleaning machine 1000 to perform dual detection, which can improve the detection accuracy and avoid working when the machine cover 100 and the machine body 200 are not properly installed, thereby helping to prevent the cleaning machine 1000 from leaking water.

[0183] Optionally, the outer surface of the first sub-plate 21 is provided with a protrusion 212 and a magnet 211. The protrusion 212 is used to trigger a contact sensor 320 mounted on the upright plate 220, and the magnet 211 is used to trigger a Hall sensor 310 mounted on the upright plate 220. The first detection element can be the protrusion 212, the second detection element can be the magnet 211, the first detector can be the contact sensor 320, and the second detector can be the Hall sensor 310. Alternatively, the first detection element can be the magnet 211, the second detection element can be the protrusion 212, the first detector can be the Hall sensor 310, and the second detector can be the contact sensor 320.

[0184] Optionally, the outer side of the first sub-plate 21 is provided with a mounting groove 2102, and the magnet 211 can be placed in the mounting groove 2102.

[0185] In some embodiments, the cleaning machine 1000 includes a controller, a contact sensor 320 and a Hall sensor 310 installed on the machine body 200. The machine cover 100 is provided with a protrusion 212 and a magnet 211. After the machine cover 100 is connected to the machine body 200, the protrusion 212 triggers the contact sensor 320 and the magnet 211 triggers the Hall sensor 310.

[0186] The controller is configured as follows: If the contact sensor 320 and the Hall sensor 310 are triggered simultaneously, it is confirmed that the cover 100 and the body 200 are installed in place. If at least one of the contact sensor 320 and the Hall sensor 310 is not triggered, it is determined that the hood 100 and the body 200 are not installed in place.

[0187] It is understandable that the triggering of the contact sensor 320 means that the protrusion 212 presses against the sensor, and the contact sensor 320 responds to the protrusion 212 by generating an electrical signal. The triggering of the Hall sensor 310 means that the magnetic field of the magnet 211 acts on the Hall sensor 310, and the Hall sensor 310 responds to the magnet 211 by generating an electrical signal.

[0188] In this way, the cleaning machine 1000 provided in this application embodiment can perform dual detection through the contact sensor 320 and the Hall sensor 310, which can improve the detection accuracy and avoid working when the machine cover 100 and the machine body 200 are not installed in place, thereby helping to prevent water leakage of the cleaning machine 1000.

[0189] The above are merely specific embodiments of this application and are not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
