Description

Technical Field

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

[0002] The sink is an indispensable part of the household kitchen. People generally complete the cleaning of food ingredients, kitchen utensils, etc. in the sink. While the sink brings convenience to people for cleaning, the difficult cleaning of the sink is also one of the problems that trouble people. For example, positions such as the gap between the side wall of the sink and the sink step are prone to accumulate oil stains, food residues, etc. If not cleaned for a long time, bacteria may breed, attracting cockroaches, insects, etc. The dirty sink usage environment not only brings the trouble of difficult cleaning to customers, reducing the usage experience of the sink, but also poses a potential safety hazard to the health of users. Currently, generally, the oil stains on the side wall and step surface of the sink are manually cleaned by a brush and clean water, or the dirty surface is manually cleaned with the help of a high-temperature steam cleaner.

[0003] However, when manually cleaning the oil stains on the side wall and the tabletop of the sink, there are problems such as low cleaning efficiency and unclean cleaning. When using a handheld high-temperature steam cleaner for cleaning, on the one hand, the high-temperature steam cleaner needs to be plugged in additionally, increasing power consumption. On the other hand, the high-temperature steam blown out by the high-temperature steam cleaner is only steam and cannot clean the dirt thoroughly. Still, it is necessary to rely on a brush and clean water for rinsing, and at the same time, attention needs to be paid to the high-temperature water vapor to avoid scalding. In addition, both methods require regular cleaning and maintenance of the sink.

[0004] Furthermore, generally, double sinks are set in modern kitchens, and one of the sinks serves as the tank body of the sink cleaning machine. For example, the Chinese invention patent "A Sink and a Cleaning Machine Using the Sink" with the application number CN202410736234.6 (publication number CN118633878A), and the Chinese utility model patent "Sink Dishwasher and Garbage Disposal Integrated Machine" with the patent number ZL202322640856.2 (authorization announcement number CN220898637U), etc. Generally, multiple cleaning processes are required for the cleaning machine. The wastewater generated in the third and fourth cleaning processes is relatively clean, and directly discharging it into the sewer will cause water resource waste. Summary of the Invention

[0005] The first technical problem to be solved by the present invention is to provide a self-cleaning sink 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 cleaning machine with the above self-cleaning sink structure in view of the prior art.

[0007] The technical solution adopted by the present invention to solve the above first technical problem is as follows: A self-cleaning sink structure includes a first sink with a pull-out faucet. A drainer is provided in the water outlet of the first sink. It is characterized in that a water storage chamber is provided inside the drainer, and spray holes exposed outside the first sink are circumferentially spaced apart along the upper edge of the drainer. When the pull-out faucet is in a pulled-down state, it can be detachably connected to the drainer. The water storage inlet of the water storage chamber is in fluid communication with the water outlet of the pull-out faucet, and the water storage outlets of the water storage chamber are respectively in fluid communication with the spray holes on the drainer.

[0008] Further, the inside of the drainer is hollow, and its inner cavity forms the above-mentioned water storage chamber. An installation opening for the pull-out faucet to be installed is provided on the top wall of the drainer, and this installation opening is the water storage inlet of the water storage chamber. This can make the internal structure of the drainer simple and facilitate the connection between the pulled-down pull-out faucet and the drainer.

[0009] Further, the drainer is vertically arranged and has a circular cross-section. When the pull-out faucet is connected to the drainer, the two are vertically aligned.

[0010] Moreover, the top end of the side wall of the water storage chamber is circumferentially open and horizontally recessed outward to form a spray ring groove opening inward. The notch of this spray ring groove is the water storage outlet, and the spray holes are circumferentially spaced apart on the outer groove wall of the spray ring groove. By providing the spray ring groove, the water entering the water storage chamber can be orderly guided to each spray hole, so that the water can better spray out from each spray hole and avoid kinetic energy loss caused by water turbulence in the water storage chamber.

[0011] Further, the spray ring groove extends horizontally in a circumferential direction in a slit shape, and the cross-section of its outer end is larger than that of its inner end. Each spray hole is opened at the outer end of the spray ring groove and is circumferentially opposite to the water storage outlet inside and outside. The slit-shaped design enables the spray ring groove to pressurize the water flow while playing a guiding role, and after pressurization, the cross-section of the outer end is increased to achieve the role of re-guiding the water flow, so that the water flow can be quickly ejected from each spray hole.

[0012] Further, the cross-sectional size of the water storage chamber increases from bottom to top, and the bottom wall of the water storage chamber bulges upward at its center. This makes the water in the water storage chamber tend to flow towards the spray ring groove, which is beneficial to better guiding the water to each spray hole.

[0013] Further, the drainer has a circular cross-section. When the pull-out faucet is connected to the drainer, the two are vertically aligned and connected by a buckle structure. This facilitates the disassembly and assembly of the pull-out faucet and the drainer.

[0014] Furthermore, the installation opening is circular and matches the size of the lower end of the above-mentioned pull-out faucet. The snap structure includes a snap groove provided on one of the rim of the installation opening and the lower end of the pull-out faucet, and a snap block provided on the other and used to snap into the above-mentioned snap groove. In this way, snapping the snap block into the snap groove can achieve the disassembly and assembly of the pull-out faucet and the drainer.

[0015] Furthermore, it further includes a vision sensor for collecting image information of the inner surface of the first sink. Through the vision sensor, the dirt condition of the inner surface of the first sink can be monitored. When the dirt level reaches the set standard, the self-cleaning of the first sink is started, and at the same time, a suitable cleaning method can be selected according to the dirt level.

[0016] Furthermore, the rear end of the top of the first sink has a horizontally extending mounting table, and a square base for mounting the above-mentioned pull-out faucet is convexly provided on this mounting table.

[0017] It further includes a second sink arranged side by side with the first sink on the left and right. The second sink has a door body for covering the upper opening thereof. The above-mentioned vision sensor includes a first vision sensor and a second vision sensor. Among them, the first vision sensor is arranged on the front side of the above-mentioned base, and the second vision sensor is arranged on the outer side of the door body adjacent to the first sink. Thus, the dirt condition of the inner surface of the first sink can be monitored better.

[0018] The technical solution adopted to further solve the above-mentioned second technical problem is: a cleaning machine, which is characterized in that it includes the self-cleaning sink structure as described above.

[0019] Compared with the prior art, the advantages of the present invention are as follows: A water storage chamber is provided inside the drainer, and a water spraying hole communicating with the water storage chamber is opened. In the state where the pull-out faucet is detachably connected to the drainer, the water of the pull-out faucet enters the water storage chamber, and then sprays out from each water spraying hole and sprays onto the inner surface of the first sink, realizing the automatic cleaning of the inner surface of the first sink. Compared with the existing cleaning methods, the present invention can achieve the automatic cleaning of the first sink, not only with high cleaning efficiency, but also the inner surface of the first sink can be rinsed by spraying to achieve a better cleaning effect.

It 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 disclosed embodiments of the present invention can be arranged in different directions, these terms indicating directions are only for illustration and should not be regarded as limitations. For example, "upper" and "lower" are not necessarily limited to the directions opposite to or consistent with the direction of gravity. In addition, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features.

[0028] As Figures 1 - 6 shown, a cleaning machine includes a self-cleaning sink structure, and the self-cleaning sink structure includes a first sink 1 and a second sink 2 arranged side by side from left to right. Among them, the second sink 2 constitutes the cleaning inner tank of the cleaning machine, and a door body 21 is covered on the upper opening of the second sink 2.

[0029] Furthermore, the above-mentioned first sink 1 has a pull-out faucet 4, and a drainer 3 is arranged in the water outlet 11 of the first sink 1. A water storage chamber 30 is arranged inside the drainer 3, and spray holes 31 exposed outside the first sink 1 are circumferentially spaced apart on the drainer 3. When the above-mentioned pull-out faucet 4 is in the pulled-down state, it can be detachably connected to the above-mentioned drainer 3, and the water storage inlet of the above-mentioned water storage chamber 30 is in fluid communication with the water outlet (not shown, formed by the water outlet holes arranged at the bottom of the pull-out faucet 4) of the above-mentioned pull-out faucet 4, and the water storage outlet 331 of the water storage chamber 30 is respectively in fluid communication with each spray hole 31 on the drainer 3.

[0030] As can be seen from the above, a water storage chamber 30 is provided inside the drainer 3 of the present invention, and a water spraying hole 31 communicating with the water storage chamber 30 is opened. When the pull-out faucet 4 is detachably connected to the drainer 3, the water of the pull-out faucet 4 enters the water storage chamber 30, and then sprays out from each water spraying hole 31 to spray the inner surface of the first water tank 1, realizing the automatic cleaning of the inner surface of the first water tank 1. Compared with the existing cleaning method, the present invention can realize the automatic cleaning of the first water tank 1, not only with high cleaning efficiency, but also can achieve a better cleaning effect by spraying the inner surface of the first water tank 1.

[0031] Furthermore, the inside of the above-mentioned drainer 3 is hollow, its inner cavity forms the above-mentioned water storage chamber 30, and an installation opening 32 for embedding the above-mentioned pull-out faucet 4 is opened on the top wall of the drainer 3, and this installation opening 32 is the water storage inlet of the above-mentioned water storage chamber 30. Thereby, the internal structure of the drainer 3 can be made simple, and it is convenient for the pulled-down pull-out faucet 4 to be connected to the drainer 3.

[0032] Specifically, the above-mentioned drainer 3 is vertically arranged and has a circular cross-section. When the above-mentioned pull-out faucet 4 is connected to the drainer 3, the two are vertically aligned. And, the top end of the side wall of the above-mentioned water storage chamber 30 is circumferentially opened and horizontally recessed outward to form a water spraying ring groove 33 with an inward opening. The notch of this water spraying ring groove 33 is the above-mentioned water storage outlet 331, and the water spraying holes 31 are circumferentially spaced apart on the outer groove wall of the water spraying ring groove 33. By providing the water spraying ring groove 33, the water entering the water storage chamber 30 can be orderly guided to each water spraying hole 31, so that the water can better spray out from each water spraying hole 31, and avoid the kinetic energy loss caused by the turbulent flow of the water in the water storage chamber 30.

[0033] In this embodiment, preferably, the above-mentioned water spraying ring groove 33 is in the shape of a horizontally extending slit along the circumference, and the cross-section of its outer end is larger than that of the inner end. Each water spraying hole 31 is opened at the outer end of the water spraying ring groove 33 and is circumferentially opposite to the above-mentioned water storage outlet 331 inside and outside. The slit-shaped design enables the water spraying ring groove 33 to pressurize the water flow while playing a guiding role, and after pressurization, the cross-section of the outer end is increased to achieve the role of re-guiding the water flow, so that the water flow can be quickly sprayed out from each water spraying hole 31. Further preferably, the cross-sectional size of the above-mentioned water storage chamber 30 increases from bottom to top, and the bottom wall of the water storage chamber 30 bulges upward at its center. Thereby, the water in the water storage chamber 30 has a tendency to flow towards the water spraying ring groove 33, which is beneficial to better guiding the water to each water spraying hole 31. In this embodiment, the above-mentioned drainer 3 includes a disc-shaped base 3a and an annular cover body 3b covering the upper opening of the base 3a, as Figure 5 and Figure 6 shown. And, the above-mentioned cover body 3b and the base 3a are buckled up and down to form the above-mentioned water spraying ring groove 33, and the above-mentioned water spraying holes 31 are opened on the above-mentioned cover body 3b.

[0034] Moreover, in this embodiment, a housing 6 is provided over the water inlet 11, and an installation ring groove 35 is recessed along the circumference at the lower end of the water outlet 3. A sealing ring 7 is embedded in the installation ring groove 35. When the water outlet 3 is embedded in the water inlet 11, the sealing ring 7 is clamped between the water outlet 3 and the housing 6 along the circumference (at this time, the sealing ring 7 undergoes a certain deformation). When the pull-out faucet 4 is connected to the water outlet 3 and the pull-out faucet 4 is in an open state, the water flowing out of the pull-out faucet 4 exerts a downward pressure on the water outlet 3, so that the sealing ring 7 further deforms, thereby better sealing the water inlet 11. At this time, if the pull-out faucet 4 is closed, the pressure applied to the water outlet 3 disappears, and the sealing ring 7 resumes its original shape, forming a circumferential gap between the sealing ring 7 and the inner surface of the upper end of the housing 6. At this time, the water in the first water tank 1 can flow out through this gap. In this way, by intermittently opening and closing the pull-out faucet 4, intermittent automatic drainage of the first water tank 1 can be achieved, avoiding the water level in the first water tank 1 being too high and affecting the cleaning effect.

[0035] Furthermore, when the pull-out faucet 4 is connected to the water outlet 3, the two are vertically aligned and connected by a snap structure, which facilitates the disassembly and assembly of the pull-out faucet 4 and the water outlet 3. Still further, the installation opening 32 is circular and matches the size of the lower end of the pull-out faucet 4. The snap structure includes a snap groove 34 provided on either the rim of the installation opening 32 or the lower end of the pull-out faucet 4, and a snap block 41 provided on the other and used to snap into the snap groove 34. In this way, snapping the snap block 41 into the snap groove 34 can achieve the disassembly and assembly of the pull-out faucet 4 and the water outlet 3. In this embodiment, specifically, the snap blocks 41 are circumferentially and evenly provided at the lower end of the pull-out faucet 4, and the snap grooves 34 corresponding to the snap blocks 41 one by one are provided along the circumference on the rim of the installation opening 32.

[0036] Further, it further includes a vision sensor for collecting image information of the inner surface of the first water tank 1. Through the vision sensor, the dirt condition of the inner surface of the first water tank 1 can be monitored. When the dirt degree reaches the set standard, the self-cleaning of the first water tank 1 is started, and at the same time, a suitable cleaning method can be selected according to the dirt degree. Specifically, the rear end of the top of the first water tank 1 has a horizontally extending mounting table 12, and a square base 13 for mounting the above-mentioned pull-out faucet 4 is convexly provided on the mounting table 12. It further includes a second water tank 2 arranged side by side with the first water tank 1 on the left and right. The second water tank 2 has a door body 21 for covering the upper opening thereof. The above-mentioned vision sensor includes a first vision sensor 51 and a second vision sensor 52. Among them, the first vision sensor 51 is arranged on the front side surface of the base 13, and the second vision sensor 52 is arranged on the outer side surface adjacent to the first water tank 1 of the door body 21, so as to better monitor the dirt condition of the inner surface of the first water tank 1.

[0037] As used in the present invention, "fluid communication" refers to the spatial position relationship between two components or parts (hereinafter uniformly referred to as the first part and the second part respectively), that is, a fluid (gas, liquid or a mixture of both) can flow from the first part along a flow path and / or be transported to the second part. It can be that the first part and the second part are directly connected, or the first part and the second part are indirectly connected through at least one third party. The third party can be a fluid passage such as a pipe, a channel, a conduit, a flow guide, a hole, a groove, etc., or a chamber allowing the fluid to flow through or a combination of the above.
