Description

Technical Field

[0001] The invention relates to the field of cleaning machines, and in particular to a self-cleaning water tank structure and a cleaning machine. Background Art

[0002] The sink is an indispensable part of the family kitchen. People usually wash food ingredients and kitchen utensils in the sink. While the sink brings convenience to people, the difficulty of cleaning the sink is also one of the problems that bothers people. For example, the side walls of the sink and the gap between the sink steps are prone to accumulate oil stains, food residues, etc. If they are not cleaned for a long time, they may breed bacteria and attract cockroaches and insects. The dirty sink environment not only brings the trouble of difficult cleaning to customers, reduces the user experience of the sink, but also poses a safety hazard to the health of users. At present, the oil stains on the side walls and steps of the sink are generally cleaned manually with a brush and clean water, or the dirty countertops are manually cleaned with the help of a high-temperature steam cleaner.

[0003] However, purely manual cleaning of the sink sidewalls and countertops has problems such as low cleaning efficiency and incomplete cleaning. On the one hand, a handheld high-temperature steam cleaner needs to be plugged in, which increases power consumption. On the other hand, the high-temperature steam from a high-temperature steam cleaner only blows out steam, which cannot clean the dirt. It still needs to be rinsed with a brush and clean water, and it is necessary to pay attention to the high-temperature steam to avoid burns. In addition, both methods require regular cleaning and maintenance of the sink.

[0004] Furthermore, modern kitchens generally have double sinks, one of which is used as the body of a sink cleaning machine, for example, the Chinese invention patent "A sink and a cleaning machine using the sink" with application number CN202410736234.6 (publication number CN118633878A), the Chinese utility model patent "Sink dishwasher and garbage disposal integrated machine" with patent number ZL202322640856.2 (authorization announcement number CN220898637U), etc. The cleaning process of the cleaning machine generally requires multiple cleanings, among which the wastewater generated by the third and fourth cleanings is relatively clean, and directly discharging it into the sewer will cause a waste of water resources. Summary of the invention

[0005] The first technical problem to be solved by the present invention is to provide a self-cleaning water tank structure with high cleaning efficiency and good cleaning effect in view of the prior art.

[0006] The second technical problem to be solved by the present invention is to provide a self-cleaning water tank structure with high cleaning efficiency, good cleaning effect and simple internal structure in view of the prior art.

[0007] The third technical problem to be solved by the present invention is to provide a cleaning machine with the above-mentioned self-cleaning water tank structure in view of the prior art.

[0008] The technical solution adopted by the present invention to solve at least one of the above-mentioned technical problems is: a self-cleaning water tank structure, including a first water tank, a drain is arranged in the water outlet of the first water tank, and the characteristic is that a water storage chamber is arranged inside the drain, and water spray holes are arranged at intervals along the circumference of the drain, which are always exposed in the first water tank and communicated with the above-mentioned water storage chamber, and also include a lifting mechanism for lifting the above-mentioned drain up and down.

[0009] Furthermore, the lifting mechanism includes a driving device for driving the water tank to move downward and an elastic member arranged under the water tank and used to support the water tank.

[0010] In the initial state, the drain is embedded in the drain port, and the elastic member is in a compressed state. When the self-cleaning mode starts, the drain is separated from the drain port, and the elastic member releases its elastic force to push the drain upward to the highest position. In this way, the drain can be lifted up and down by the cooperation of the driving force of the driving device and the elastic force of the elastic member.

[0011] Furthermore, the driving device is a pull-out faucet installed on the first water tank and having an adjustable water output, and the drain is hollow inside, the inner cavity of which constitutes the water storage chamber, and a mounting opening for the pull-out faucet to be embedded is provided on the top wall of the drain.

[0012] In the self-cleaning mode, when the downward pressure applied to the drain by the water pressure of the pull-pull faucet is greater than the upward supporting force of the elastic member on the drain, the drain moves downward and the elastic member is compressed, and when the water output of the pull-pull faucet decreases and the downward pressure applied to the drain by the water pressure of the pull-pull faucet is less than the upward supporting force of the elastic member on the drain, the drain moves upward and resets under the elastic force of the elastic member. The driving device in the present invention can be implemented in a variety of ways, and a pull-pull faucet is preferred. Through the water output of the pull-pull faucet, on the one hand, a downward driving force can be applied to the drain, and by controlling the water output of the pull-pull faucet, the size of the driving force applied to the drain can be adjusted, and on the other hand, a water source can be provided for the water storage chamber of the drain. In addition, the pull-pull faucet is a device originally provided with the first water sink, so that the internal structure of the first water sink can be simple.

[0013] Furthermore, the water outlet is circumferentially connected to a vertically extending cover shell, and a drainage port is provided at the bottom of the cover shell.

[0014] The elastic member is a vertically arranged spring, the upper end of which is connected to the bottom of the drain and the lower end of which is connected to the cover, so that the elastic member can be stably installed, and the drain can be better lifted up and down under the elastic force of the elastic member.

[0015] Furthermore, the upper end of the elastic member is detachably connected to the bottom of the drain, and / or in the initial state, the drain is detachably connected to the edge of the drain outlet along the circumferential direction, and the connection force between the two is greater than the elastic force of the elastic member. In this way, the elastic member and the drain can be disassembled in the initial state, and the two can be assembled again when the first water tank needs to be self-cleaned. Alternatively, the elastic member and the drain can be always connected, and the connection between the drain and the edge of the drain outlet prevents the drain from being ejected from the drain outlet by the elastic force of the elastic member in the initial state.

[0016] Furthermore, the cross-sections of the drain and the cover are both circular, and the two are arranged vertically opposite to each other, and the elastic member extends along the central axis direction of the two.

[0017] In addition, a mounting seat for detachably mounting the lower end of the elastic member is provided at the center of the bottom wall of the housing, and drainage holes are provided at intervals along the circumference with the mounting seat as the center, and the drainage holes are arranged to form the drainage port, so as to facilitate the disassembly and assembly of the lower end of the elastic member and the housing.

[0018] Furthermore, the cross section of the drain is circular, and when the pull-out faucet is connected to the drain, the two are facing each other vertically.

[0019] Furthermore, the top of the side wall of the water storage chamber is open in the circumferential direction and is horizontally recessed outward to form a water outlet annular groove that is open inward, and the notch of the water outlet annular groove is a water through hole, and the outer groove wall of the water outlet annular groove is provided with the water spray holes at intervals in the circumferential direction. By providing the water outlet annular groove, the water entering the water storage chamber can be guided to the water spray holes in an orderly manner, so that the water can be sprayed out from the water spray holes better, and the turbulence of the water flow in the water storage chamber can be avoided to cause kinetic energy loss.

[0020] Furthermore, the water outlet annular groove is in the shape of a slit extending horizontally along the circumferential direction, and the cross section of the outer end thereof is enlarged, and each water spray hole is provided at the outer end and is opposite to the water through hole in the inner and outer sides along the circumferential direction. The slit-shaped design enables the water outlet annular groove to pressurize the water flow while playing the role of diversion, and after pressurization, the cross section of the outer end is enlarged to achieve the role of diversion again, so that the water flow can be quickly sprayed out from each water spray hole.

[0021] Furthermore, the cross section of the drain is circular, and when the pull-out faucet is connected to the drain, the two are vertically aligned and snap-connected, which ensures a stable connection between the pull-out faucet and the drain and facilitates assembly and disassembly of the pull-out faucet and the drain.

[0022] The technical solution adopted to further solve the third technical problem mentioned above is: a cleaning machine, characterized in that it includes the self-cleaning water tank structure as described above.

[0023] Compared with the prior art, the advantages of the present invention are: a water storage chamber is provided inside the drain, and a water spray hole communicating with the water storage chamber is provided on the drain, so that the water in the water storage chamber can be sprayed out from each water spray hole and sprayed to the inner surface of the first water tank, thereby realizing automatic cleaning of the inner surface of the first water tank. Compared with the existing cleaning method, the present invention can realize automatic cleaning of the first water tank, not only with high cleaning efficiency, but also through the lifting mechanism to realize the up and down lifting of the drain, realize the up and down spraying of the inner surface of the first water tank, and ensure the cleaning effect of the inner surface of the first water tank.

[0031] The present invention is further described in detail below with reference to the accompanying drawings.

[0032] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential" and the like indicate the orientation or position relationship based on the orientation or position relationship shown in the drawings, which is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Since the embodiments disclosed in the present invention can be set in different directions, these terms indicating directions are only for illustration 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. In addition, the features defined as "first" and "second" may explicitly or implicitly include one or more of such features.

[0033] like Figures 1 to 7 As shown, a cleaning machine comprises a first water tank 1 and a second water tank 2 arranged side by side. In this embodiment, the first water tank 1 constitutes a self-cleaning water tank structure, and the second water tank 2 is a cleaning tank of the cleaning machine, and a door body 21 is provided on the top opening of the second water tank 2. Further, a drain 3 is provided in the water outlet 11 of the first water tank 1, and a water storage chamber 30 is provided inside the drain 3, and water spray holes 31 are provided on the drain 3 at intervals along the circumference, which are always exposed in the first water tank 1 and communicated with the water storage chamber 30, and a lifting mechanism for lifting the drain 3 up and down is also included.

[0034] It can be seen that the drain 3 of the present invention is provided with a water storage chamber 30 inside, and the drain 3 is provided with a water spray hole 31 communicating with the water storage chamber 30. In this way, the water in the water storage chamber 30 can be sprayed out from each water spray hole 31, spraying the inner surface of the first water tank 1, and realizing automatic cleaning of the inner surface of the first water tank 1. Compared with the existing cleaning method, the present invention can realize automatic cleaning of the first water tank 1, not only with high cleaning efficiency, but also through the lifting mechanism to realize the up and down lifting of the drain 3, realize the up and down spraying of the inner surface of the first water tank 1, and ensure the cleaning effect of the inner surface of the first water tank 1.

[0035] Furthermore, the lifting mechanism includes a driving device for driving the drain 3 to move downward and an elastic member 5 disposed under the drain 3 and used to support the drain 3. In the initial state, the drain 3 is embedded in the drain port 11, and the elastic member 5 is in a compressed state. When the self-cleaning mode starts, the drain 3 is separated from the drain port 11, and the elastic member 5 releases the elastic force to push the drain 3 upward to the highest position. In this way, the drain 3 can be lifted up and down by the cooperation of the driving force of the driving device and the elastic force of the elastic member 5.

[0036] The driving device in the present invention can be implemented in a variety of specific ways, and preferably is a pull-out faucet 4. Specifically, the driving device is a pull-out faucet 4 installed on the first water tank 1 and having an adjustable water output. The drain 3 is hollow inside, and its inner cavity constitutes the water storage chamber 30. The top wall of the drain 3 is provided with an installation port for the pull-out faucet 4 to be embedded. In the self-cleaning mode, when the downward pressure of the water pressure of the pull-out faucet 4 applied to the drain 3 is greater than the upward support force of the elastic member 5 on the drain 3, the drain 3 moves downward and the elastic member 5 is compressed. When the water output of the pull-out faucet 4 decreases and the downward pressure of the water pressure of the pull-out faucet 4 applied to the drain 3 is less than the upward support force of the elastic member 5 on the drain 3, the drain 3 moves upward and resets under the action of the elastic force of the elastic member 5. The water output of the pull-out faucet 4 can, on the one hand, apply a downward driving force to the drain 3, and by controlling the water output of the pull-out faucet 4, the magnitude of the driving force applied to the drain 3 can be adjusted, and on the other hand, a water source can be provided for the water storage chamber 30 of the drain 3. In addition, the pull-out faucet 4 is a device originally provided by the first water tank 1, that is, the present invention does not need to provide a separate driving device, so that the internal structure of the first water tank 1 can be simple.

[0037] Furthermore, the water outlet 11 is circumferentially covered with a vertically extending cover shell 6, the bottom of which is provided with a drain port 61, and the elastic member 5 is a vertically arranged spring, the upper end of which is connected to the bottom of the drain 3 and the lower end of which is connected to the cover shell 6. Thus, the elastic member 5 can be stably installed, and the drain 3 can be better lifted up and down under the elastic force of the elastic member 5.

[0038] Furthermore, the upper end of the elastic member 5 is detachably connected to the bottom of the drain 3 (for example, a snap hole is provided at the bottom of the drain 3, and the upper end of the elastic member 5 is snapped into the snap hole), and / or in the initial state, the drain 3 is detachably connected to the edge of the drain outlet 11 along the circumferential direction (for example, snap connection, etc.), and the connection force between the two is greater than the elastic force of the elastic member 5. In this way, the elastic member 5 and the drain 3 can be disassembled in the initial state, and the two can be assembled when the first water tank 1 needs to be self-cleaned. Alternatively, the elastic member 5 and the drain 3 can also be kept in a connected state at all times, and the connection between the drain 3 and the edge of the drain outlet 11 can prevent the drain 3 from being ejected from the drain outlet 11 by the elastic force of the elastic member 5 in the initial state.

[0039] Furthermore, the cross-sections of the drain 3 and the cover 6 are both circular, and the two are arranged vertically opposite to each other, and the elastic member 5 extends along the central axis direction of the two. In addition, a mounting seat 62 for detachably mounting the lower end of the elastic member 5 is provided at the center of the bottom wall of the cover 6, and drainage holes 611 are provided at intervals along the circumferential direction with the mounting seat 62 as the center, and the drainage holes 611 are arranged to form the drainage port 61, so as to facilitate the disassembly and assembly of the lower end of the elastic member 5 and the cover 6.

[0040] Specifically, in this embodiment, a vertically arranged guide tube 7 is also included, and the guide tube 7 is a bellows that can be extended and retracted up and down, and the elastic member 5 is spirally embedded in the tube wall of the guide tube 7 along the length direction, so as to guide the deformation of the elastic member 5, thereby making the drain 3 better rise and fall. In addition, a mounting hole 621 is opened on the mounting seat 62, and the lower end of the guide tube 7 is clamped in the mounting hole 621.

[0041] Furthermore, the cross section of the drain 3 is circular, and when the pull-out faucet 4 is connected to the drain 3, the two are facing each other vertically. In addition, the top of the side wall of the water storage chamber 30 is open in the circumferential direction and is horizontally recessed outward to form an inwardly open water outlet annular groove 301, and the notch of the water outlet annular groove 301 is a water through hole 3011, and the water spray holes 31 are spaced apart in the circumferential direction on the outer groove wall of the water outlet annular groove 301. By providing the water outlet annular groove 301, the water entering the water storage chamber 30 can be guided to each water spray hole 31 in an orderly manner, so that the water can be sprayed out from each water spray hole 31 better, and the turbulence of the water flow in the water storage chamber 30 can be avoided to cause kinetic energy loss. Preferably, the water outlet annular groove 301 is in the shape of a slit extending horizontally in the circumferential direction, and the cross section of its outer end is enlarged, and each water spray hole 31 is opened at the outer end and is opposite to the water through hole 3011 in the circumferential direction. The slit-shaped design enables the water outlet annular groove 301 to pressurize the water flow while playing a guiding role, and after pressurization, it can achieve a second guiding role by increasing the cross section of the outer end, so that the water flow can be quickly ejected from each water spray hole 31.

[0042] Furthermore, when the pull-out faucet 4 is connected to the drain 3, the two are aligned vertically and connected by snaps. On the one hand, the pull-out faucet 4 is firmly connected to the drain 3, and on the other hand, the pull-out faucet 4 and the drain 3 are easily disassembled. Specifically, snap blocks 33 are convexly provided at intervals along the circumferential direction at the lower end of the drain 3, and snap grooves 321 corresponding to the snap blocks 33 and for the corresponding snap blocks 33 to be snapped into are concavely provided on the edge of the installation opening 32.

[0043] The "fluid connection" referred to in the present invention refers to the spatial position relationship between two components 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 to each other, or the first part and the second part can be indirectly connected through at least one third party. The third party can be a fluid channel such as a pipe, channel, duct, guide member, hole, groove, etc., or it can be a chamber allowing fluid to flow through, or a combination of the above.
