Description

Technical Field

[0001] The invention relates to the field of water tanks, and in particular to a water tank drainage system, an automatic unblocking method, a water tank and a cleaning machine. Background Art

[0002] Modern kitchens are generally equipped with double sinks on the countertops of the cabinets, one of which is used as an ordinary sink, and the other is used as the tank body of a sink cleaning machine (dishwasher). 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 "A sink type cleaning machine" with patent number ZL202322652519.5 (authorization announcement number CN220937980U), etc.

[0003] Furthermore, the double sink shares a drainage system, for example, the Chinese utility model patent with patent number ZL 202022833984.5 (authorization announcement number CN214940737U), the Chinese invention patent with patent number ZL 202111514342.1 (authorization announcement number CN114343530A), etc. The existing sink drainage system, whether it uses gravity drainage or forced drainage, is prone to blockage after long-term use, affecting the use of the sink and dishwasher. Moreover, after the blockage occurs, it can only be cleaned manually, and it is easy to be blocked again and again after cleaning, which seriously affects the user experience.

[0004] In addition, the dishwasher needs to dry the dishes in the cleaning chamber after cleaning. During the drying process, the exhaust fan is used to draw the hot and humid air in the cleaning chamber into the drying channel. The hot and humid air is then discharged in sequence through the drying channel → exhaust fan → drying channel bottom. Summary of the invention

[0005] The first technical problem to be solved by the present invention is to provide a sink drainage system with smooth drainage and automatic unblocking function in view of the prior art.

[0006] The second technical problem to be solved by the present invention is to provide a sink drainage system with smooth drainage and automatic unblocking function in view of the prior art, and the unblocking effect of the sink drainage system is good.

[0007] The third technical problem to be solved by the present invention is to provide a water sink drainage system which is smooth and has an automatic unblocking function in view of the prior art, and the water sink drainage system can prevent the cabinet from getting damp.

[0008] The fourth technical problem to be solved by the present invention is to provide an automatic unblocking method for the above-mentioned sink drainage system in view of the prior art, and the automatic unblocking method has a good unblocking effect.

[0009] The fifth technical problem to be solved by the present invention is to provide a sink with the above sink drainage system in view of the prior art.

[0010] The sixth technical problem to be solved by the present invention is to provide a cleaning machine with the above-mentioned water tank in view of the prior art.

[0011] The technical solution adopted by the present invention to solve at least one of the above technical problems is: a sink drainage system, including a drain and a drain pipe, the drain includes a cylindrical shell, the water inlet at the upper end of the shell is used to be connected to the drain outlet of the sink, and the drain outlet at the lower end is connected to the drain pipe, characterized in that:

[0012] The down pipe is a deformable tube that can undergo radial deformation under its own internal pressure and can return to its original shape, and an air inlet is provided on the side wall of the shell, and the air inlet is used to be fluidically connected to the exhaust port of the cleaning machine.

[0013] Furthermore, a shielding member is disposed transversely in the shell for shielding the water outlet, and the shielding member forms an annular gap along the circumference for water to flow through and toward the water outlet, and the shielding member is located above the air inlet. This not only ensures that the water entering the drain flows smoothly toward the water outlet, but also facilitates the gas entering the air inlet to mix into the water flow and increase the pressure at the blocked part of the drain pipe, thereby improving the unblocking effect of the blocked part.

[0014] Furthermore, it also includes an elastic member arranged along the circumference of the above-mentioned shielding member. When the above-mentioned air inlet is in the state of air intake, the above-mentioned shielding member moves upward, and the above-mentioned elastic member is compressed so that the shielding member has a tendency to move downward. In this way, under the action of the elastic member, secondary pressurization of the blocked part of the sewer pipe can be achieved, further improving the unblocking effect of the blocked part.

[0015] Furthermore, the lower end of the shell is circumferentially contracted to form a contracted end, the air inlet is provided on the side wall of the contracted end, the lower end of the contracted end is the water outlet, and the edge of the upper end extends vertically upward along the circumferential direction to form an extension pipe.

[0016] The shielding member is a cover body that is arranged above the upper tube opening of the extension tube, and the annular gap is left between the cover body and the extension tube along the circumferential direction. The elastic member is a spring that is sleeved outside the extension tube, and the spring is located between the extension tube and the shielding member, and the lower end of the spring is limited by the lower limit of the shielding member, and the upper end is limited by the upper limit of the extension tube. Thus, the shielding member can be better arranged above the drain and the elastic member can be stably installed, and the annular gap can be better formed, and when the elastic member is compressed and deformed, the shielding member can have a better tendency to move downward.

[0017] Furthermore, the cross section of the shielding member is circular and is arranged vertically opposite to the extension tube. The inner side surface of the shielding member is provided with lower limit blocks at intervals along the circumference, and the outer side surface of the extension tube is provided with upper limit blocks at intervals along the circumference. The upper end of the elastic member abuts against each upper limit block and the lower end abuts against each lower limit block. Thus, the shielding member can better achieve the lower limit of the elastic member and the extension tube can better achieve the upper limit of the elastic member.

[0018] Furthermore, the top wall of the shielding member bulges upwards to present a spherical shape, so that the air pressure can act evenly on the shielding member, thereby enabling the shielding member to move up and down smoothly.

[0019] Furthermore, positioning blocks are protruded on the inner surface of the junction of the side wall of the shell and the above-mentioned extension tube at circumferential intervals. In the initial state, the lower end edge of the above-mentioned shielding member abuts against the positioning blocks up and down, thereby limiting the position of the shielding member and ensuring that the water flow entering the drain in the initial state can flow smoothly to the drain outlet.

[0020] Furthermore, the cross section of the junction between the side wall of the shell and the extension tube is circular and the radius decreases from top to bottom, and the shape of each positioning block is cylindrical and extends vertically. Thus, the water flow entering the drain can be guided so that the water flow can smoothly flow through the annular gap to the drain port, and the obstruction of the water flow by each positioning block can be minimized to ensure the smoothness of the water flow.

[0021] Furthermore, the downpipe is made of a flexible material and is corrugated in shape, so that the downpipe can undergo radial deformation and axial deformation simultaneously, thereby preventing the upper and lower connections of the downpipe from becoming loose due to excessive radial deformation, and ensuring the reliability of the sink downpipe system.

[0022] The technical solution adopted to further solve the fourth technical problem is: an automatic unblocking method for the sink drainage system as described above, characterized in that it includes the following steps: first, the exhaust fan of the cleaning machine is turned on, the air inlet is intaked, the shielding member is moved upward until the shielding member is stationary, the exhaust fan stops working, the air inlet stops intake, the shielding member is reset and the elastic member is restored to its original shape; then, the exhaust fan of the cleaning machine is turned on again, and the cycle is repeated in sequence. In this way, when the force exerted on the shielding member reaches a balance (that is, the upward thrust of the air pressure is equal to the downward pulling force exerted by the elastic member), the exhaust fan of the cleaning machine is suspended (that is, the air inlet stops intake), the force balance on the shielding member is broken, the elastic member quickly returns to its original state, the shielding member is reset, and then the exhaust fan is turned on again, and the cycle is repeated in sequence to achieve a pulsed pressurization effect. The unblocking effect can be significantly improved through pulsed oiling.

[0023] The technical solution adopted to further solve the fifth technical problem is: a water sink, characterized in that the water sink drainage system as described above and / or the unblocking method as described above are applied.

[0024] The technical solution adopted to further solve the sixth technical problem mentioned above is: a cleaning machine, characterized in that it has a water tank as described above.

[0025] Compared with the prior art, the advantages of the present invention are: the sewer pipe is a deformable pipe and does not deform during normal drainage. When the drainage volume is large, the sewer pipe can deform and become thicker to ensure smooth drainage. At the same time, the deformation and thickening of the sewer pipe can also allow larger particles of solid matter to pass through. Therefore, it can avoid blockage of the sewer pipe to a certain extent, which is conducive to ensuring smooth drainage.

[0026] Furthermore, an air inlet is provided on the side wall of the shell of the drain device. When the drain pipe is blocked (for example, the solid matter is viscous or large in volume, and the drain pipe becomes thicker due to the water pressure and is not sufficient for the solid matter to pass through), the cleaning machine is exhausted and the gas enters the drain device through the air inlet, thereby increasing the pressure at the blocked part of the drain pipe. The radius of the drain pipe at the blocked part is further increased to clear the blockage, and the blockage is smoothly discharged into the sewer along the drain pipe driven by the pressurized water flow, thereby achieving smooth unblocking of the drain pipe.

[0027] In addition, in the prior art, the washing machine directly exhausts the gas to the outside. Since the exhausted gas is the hot and humid gas in the drying process, it will cause the cabinet to get damp, which will affect the service life of the cabinet. In the present invention, the gas is discharged into the drain, so that the water vapor in the hot and humid gas can condense in the drain and the drain pipe, and the condensed water formed is discharged into the sewer along with the drain of the sink, thereby preventing the cabinet from getting damp and extending the service life of the cabinet.

[0033] The present invention is further described in detail below with reference to the accompanying drawings.

[0034] 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.

[0035] like Figure 1 to Figure 5 As shown, a cleaning machine comprises a first water tank 3 and a second water tank 4 which are arranged side by side and connected to each other, wherein the first water tank 3 forms a washing chamber of the cleaning machine, and a water tank drainage system 8 is arranged on the second water tank 4.

[0036] Further, if Figure 2 and Figure 3As shown, the sink drainage system 8 includes a drain 1 and a drain pipe 2. The drain 1 includes a cylindrical shell 10. The water inlet 101 at the upper end of the shell 10 is used to connect to the drain outlet of the second sink 4, and the drain pipe 2 is connected to the drain outlet 102 at the lower end. The drain pipe 2 is a deformable tube that can undergo radial deformation under its own internal pressure and can return to its original state. The side wall of the shell 10 is provided with an air inlet 103, which is used to be fluidically connected to the exhaust port (not shown) of the cleaning machine. In this embodiment, the exhaust port is connected to the air inlet of the shell through the exhaust pipe 7, as shown in FIG. Figure 2 shown.

[0037] As can be seen from the above, the drain pipe 2 in the present invention is a deformable pipe, which does not deform during normal drainage. When the drainage volume is large, the drain pipe 2 can deform and thicken to ensure the smoothness of drainage. At the same time, the deformation and thickening of the drain pipe 2 can also allow relatively large solid objects to pass through, so it can avoid the blockage of the drain pipe 2 to a certain extent, which is conducive to ensuring the smoothness of drainage. Further, an air inlet 103 is opened on the side wall of the shell 10 of the drain 1. When the drain pipe 2 is blocked (for example, the solid object is viscous or large in volume, and the deformation and thickening of the drain pipe 2 caused by the water pressure is not enough for the solid object to pass through), at this time, the cleaning machine exhausts air, and the gas enters the drain 1 through the air inlet 103, so as to increase the pressure of the blocked part of the drain pipe 2, and the radius of the drain pipe 2 at the blocked part is further increased to clear the blocked part. The blocked object is smoothly discharged into the sewer along the drain pipe 2 under the drive of the pressurized water flow, so as to achieve smooth unblocking of the drain pipe 2. In addition, in the prior art, the cleaning machine directly exhausts the gas to the outside. Since the exhausted gas is the hot and humid gas in the drying process, it will cause the cabinet to get damp, affecting the service life of the cabinet. In the present invention, by discharging the gas into the drain 1, the water vapor in the hot and humid gas can condense in the drain 1 and the drain pipe 2, and the formed condensed water is discharged into the sewer along with the drain of the second water tank 4, thereby preventing the cabinet from getting damp and extending the service life of the cabinet. Preferably, in this embodiment, the drain pipe 2 in this embodiment is made of a flexible material (such as rubber, silicone, flexible plastic, etc.) and its shape is corrugated. In this way, the drain pipe 2 can simultaneously undergo radial deformation and axial deformation, avoiding excessive radial deformation and causing the upper and lower connections of the drain pipe 2 to loosen, and ensuring the reliability of the sink drain system 8. In order to better prevent the drain pipe 2 from loosening, the upper end of the drain pipe 2 has a mounting joint 21 of a hard material, and the mounting joint 21 is connected to the drain port 102 through a mounting sleeve 91 and sealed by a sealing ring 92.

[0038] Furthermore, a shielding member 5 is horizontally disposed in the housing 10 for shielding the water outlet 102, and the shielding member 5 is circumferentially surrounded by an annular gap 50 (such as Figure 2As shown), the shielding member 5 is located above the air inlet 103. This not only ensures that the water flow entering the drain 1 flows smoothly to the drain 102, but also facilitates the gas entering the air inlet 103 to mix into the water flow and better pressurize the blocked part of the drain pipe 2, thereby improving the unblocking effect of the blocked part. Furthermore, it also includes an elastic member 6 arranged along the circumference of the shielding member 5. When the air inlet 103 is inletting air, the shielding member 5 moves upward, and the elastic member 6 is compressed, so that the shielding member 5 has a tendency to move downward. In this way, under the action of the elastic member 6, a secondary pressurization of the blocked part of the drain pipe 2 is achieved, thereby further improving the unblocking effect of the blocked part.

[0039] In this embodiment, specifically, Figure 2 As shown, the lower end of the shell 10 is circumferentially contracted to form a contracted end 10a, the air inlet 103 is opened on the side wall of the contracted end 10a, the lower end of the contracted end 10a is the water outlet 102, and the edge of the upper end extends vertically upward along the circumferential direction to form an extension tube 10b. The shielding member 5 is a cover body that is covered above the upper tube opening of the extension tube 10b, and the annular gap 50 is left between the cover body and the extension tube 10b along the circumferential direction (the lower end edge of the cover body is suspended along the circumferential direction), and the elastic member 6 is a spring that is sleeved outside the extension tube 10b, and the spring is located between the extension tube 10b and the shielding member 5, and the lower end of the spring is limited by the shielding member 5 and the upper end is limited by the extension tube 10b. This can better realize the setting of the shielding member on the drain 102 and the stable installation of the elastic member 6, and can better form the above-mentioned annular gap 50, and when the elastic member 6 is compressed and deformed, the shielding member 5 can have a better tendency to move downward.

[0040] More specifically, the cross section of the shielding member 5 is circular and is arranged vertically opposite to the extension tube 10b. The inner side surface of the shielding member 5 is provided with lower limit blocks 51 at intervals along the circumferential direction, and the outer side surface of the extension tube 10b is provided with upper limit blocks 10b1 at intervals along the circumferential direction. The upper end of the elastic member 6 is respectively against each upper limit block 10b1 and the lower end is respectively against each lower limit block 51. Thus, the lower limit of the elastic member 6 by the shielding member 5 and the upper limit of the elastic member 6 by the extension tube 10b can be better achieved. Preferably, the top wall of the shielding member 5 is raised upward and presents a spherical shape, so that the air pressure can act evenly on the shielding member 5, and then the shielding member 5 can move up and down smoothly. In addition, in this embodiment, three connection interfaces 104 are provided at intervals along the circumferential direction on the shell 10, and the outer top surface of the shielding member 5 is not higher than each connection interface 104.

[0041] Furthermore, positioning blocks 105 are convexly provided on the inner surface of the junction between the side wall of the shell 10 and the extension tube 10b at circumferential intervals. In the initial state, the lower edge of the shielding member 5 abuts against each positioning block 105 up and down, so that the shielding member 5 can be limited, ensuring that the water flow entering the drain 1 in the initial state can flow smoothly to the drain 102. Preferably, the cross-section of the junction between the side wall of the shell 10 and the extension tube 10b is circular and the radius decreases from top to bottom, and the shape of each positioning block 105 is cylindrical and extends vertically. Thereby, the water flow entering the drain 1 can be guided, so that the water flow can smoothly flow through the annular gap to the drain 102, and the obstruction of the water flow by each positioning block 105 can be minimized to ensure the smoothness of the water flow.

[0042] In order to further improve the blocking effect of the present invention, the blocking method of the present invention comprises the following steps:

[0043] First, the exhaust fan (not shown) of the cleaning machine is turned on, the air inlet 103 is inlet, and the shielding member 5 is moved upward until the shielding member 5 is stationary, the exhaust fan stops working, the air inlet 103 stops inletting air, the shielding member 5 is reset and the elastic member 6 is restored to its original shape; then, the exhaust fan of the cleaning machine is turned on again, and the cycle is repeated in sequence. In this way, when the force exerted on the shielding member 5 reaches a balance (that is, the upward thrust of the air pressure is equal to the downward pulling force exerted by the elastic member 6), the exhaust fan of the cleaning machine is suspended (that is, the air inlet 103 stops inletting air), the force balance on the shielding member 5 is broken, the elastic member 6 quickly returns to its original state, and the shielding member 5 is reset. Then, the exhaust fan is turned on again, and the cycle is repeated in sequence to achieve a pulsed pressurization effect. The pulsed oiling can significantly improve the unblocking effect.

[0044] 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.
