Description

Technical Field

[0001] This utility model relates to the field of kitchen appliance technology, and in particular to a drainage device and a dishwasher. Background Technology

[0002] As a core piece of equipment in modern kitchens, the reliability of the dishwasher's drainage system directly affects user experience and hygiene safety. The dishwasher's drainage process requires a drain pump to discharge the wastewater after washing, thereby achieving the extraction and discharge of wastewater.

[0003] Existing dishwashers typically use a top-drainage system to maintain the water level inside during the washing and rinsing processes. Residual water from the raised drain pipe can potentially flow back into the dishwasher. This residual water, due to temperature changes or microbial growth, can easily cause odors and contamination, especially noticeable in humid environments. Current technology usually adds a check valve after the drain pump to prevent this backflow. However, this design has significant limitations; water below the centerline of the drain pump cannot be completely drained, ultimately failing to improve the effectiveness of residual water contamination as expected. Furthermore, other measures to prevent residual water backflow are difficult to adapt to the structural design of existing water cups.

[0004] Therefore, how to solve the problem of residual water contamination in dishwashers while ensuring the universality of water cups has become a core need that urgently needs to be addressed. Utility Model Content

[0005] This utility model provides a drainage device and a dishwasher, which solves the problem of residual water pollution in the dishwasher while ensuring the universality of water cups.

[0006] To achieve the above objectives, this utility model provides a drainage device, comprising:

[0007] A water cup, wherein a connector is provided on the side wall of the water cup, the connector has an installation cavity, the side wall of the installation cavity has a communication port, and the side wall of the water cup has a water outlet communicating with the installation cavity;

[0008] A modified seal is disposed in the mounting cavity, and a water passage hole is formed inside the modified seal, which connects the water outlet and the connecting port.

[0010] The drainage device provided in this application embodiment, by setting a modified sealing element in the mounting cavity, changes the shape of the original mounting cavity and achieves a better sealing connection with the mounting cavity, making it easy to connect the valve body assembly to the water passage hole. This allows the valve body assembly to be arranged between the pipeline flowing from the water cup to the drainage pump assembly, thereby effectively providing a backflow prevention effect at the very front end of the drainage system, without changing the structure of the water cup. This achieves zero residual water while improving the commonality rate of parts, and the water cup has good versatility.

[0011] In one possible implementation, the modified seal includes:

[0012] The skeleton part includes a cylindrical body and an end panel. The end panel is connected to the first end of the cylindrical body. The water passage includes a connecting hole located in the cylindrical body and a clearance hole located in the end panel. The connecting hole and the clearance hole are in communication with each other.

[0013] A sealing portion is disposed on the skeleton portion, the sealing portion being used to achieve a seal between the modified seal and the mounting cavity, and / or, the sealing portion being used to achieve a seal between the modified seal and the mounting portion.

[0014] In one possible implementation, the sealing portion includes a first sealing portion disposed on the side of the end panel facing the connection hole and surrounding the periphery of the clearance hole, the mounting portion extending into the connection hole and abutting against the first sealing portion.

[0015] In one possible implementation, the aperture of the mounting cavity is larger than the aperture of the outlet, so as to form a step at the end of the mounting cavity near the outlet.

[0016] The sealing part further includes a second sealing part, which is embedded in the cylinder body. The second sealing part includes:

[0017] An external sealing portion, extending to the outer side wall of the cylinder body, abutting against the inner peripheral side wall of the mounting cavity; and / or,

[0018] An end-face sealing rib protrudes from the side of the end panel opposite to the water passage hole and abuts against the step.

[0019] In one possible implementation, the cylinder body has extrusion ribs located on the inner wall of the connecting hole and abutting against the mounting portion.

[0020] In one possible implementation, the modified seal has a drain hole on its side wall, and the water passage is connected to the communication port through the drain hole, with the drain hole and the communication port being positioned opposite each other.

[0021] In one possible implementation, the modified seal is integrally connected to the connector via secondary injection molding.

[0022] In one possible implementation, the drainage device further includes a drainage pump assembly, which is connected to the communication port via a water inlet pipe. The drainage pump assembly is disposed on the outer wall of the water cup via a connecting component, which includes:

[0023] A first connector is disposed on the outer wall of the water cup, and the first connector includes at least one first engaging portion;

[0024] A second connector is disposed on the outer wall of the drain pump assembly, and the second connector includes at least one second engaging portion.

[0026] In one possible implementation, the drain pump assembly includes a base, one of the base and the second connector having a mating hole, and the other of the base and the second connector being connected to a fixing post that extends into and is flexibly connected to the mating hole.

[0027] This application also provides a dishwasher, including the aforementioned drainage device.

[0028] The present application provides a drainage device and dishwasher. The valve body assembly is closer to the water outlet than the drain pump assembly. The valve body assembly can effectively block the reverse flow of water from the water cup to the drain pump assembly. The valve body assembly can block the pipeline between the water cup and the drain pump assembly, cut off the backflow path from the upstream of the water flow, and prevent the water flowing into the drain pump assembly from flowing back into the water cup to further reduce the residual water in the water cup and reduce the risk of pollution. In addition, with the suction of the drain pump assembly itself, it helps to empty the water flowing from the water cup into the drain pump assembly.

[0051] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0052] In related technologies, the drain pump assembly is directly connected to the outer wall of the water cup, providing drainage power for the dishwasher. A solution to the problem of residual water contamination in dishwashers is to add a check valve structure at the rear end of the original drain pump to prevent residual water backflow. The check valve can block water flow in one direction, effectively preventing water from external pipes or already drained water from flowing back into the dishwasher after the drain pump stops working, thus solving the problem of water backflow contamination. This solution does not change the original structure of the dishwasher's water cup; however, because the check valve is installed at the rear end of the drain pump, a low-level dead zone is formed below the center line of the drain pump. Water in this area cannot be discharged by the suction force generated by the drain pump, easily leading to residual water.

[0053] The drainage device and dishwasher provided in the embodiments of this utility model are described below with reference to the accompanying drawings.

[0054] refer to Figure 1 and Figure 2 As shown, this application embodiment provides a drainage device, including: a water cup 10, a modified seal 20, and a valve body assembly 30. A connector 11 is provided on the side wall of the water cup 10, and the connector 11 has a mounting cavity 111. A connecting port 112 is opened on the side wall of the mounting cavity 111, and a water outlet 13 communicating with the mounting cavity 111 is opened on the side wall of the water cup 10. The modified seal 20 is disposed within the mounting cavity 111, and a water passage hole 21 is formed inside the modified seal 20, which communicates with the water outlet 13 and the connecting port 112. The valve body assembly 30 includes a mounting base 31, which has a mounting portion 311 connected to the water passage hole 21. The mounting portion 311 has a water flow channel 312 connecting the water passage hole 21 and the connecting port 112. The valve body assembly 30 is used to control the opening and closing of the water flow channel 312 to provide a drainage on / off function.

[0055] The drainage device provided in this application embodiment, by setting the modified sealing member 20 in the mounting cavity 111, changes the shape of the original mounting cavity 111 and achieves a better sealing connection with the mounting cavity 111, which facilitates the connection of the valve body assembly 30 to the water passage 21. This allows the valve body assembly 30 to be arranged between the pipeline flowing from the water cup 10 to the drainage pump assembly 40, thereby effectively providing a backflow prevention effect at the front end of the drainage system, without changing the structure of the water cup 10. This achieves no residual water while improving the commonality rate of parts, and the water cup 10 has good versatility.

[0056] The inner wall of the connector 11 has a notch 114, which is located at the end of the mounting cavity 111 connected to the outlet 13. This makes the shape of the mounting cavity 111 irregular. The abnormal shape of the inner wall of the mounting cavity 111 at the notch 114 increases the difficulty of the sealing design and may lead to sealing failure. In this application, by setting a modified seal 20, an effective seal is achieved between the outer wall of the modified seal 20 and the inner wall of the mounting cavity 111. Furthermore, the water passage hole 21 opened in the modified seal 20 is circular in shape, and the water passage hole 21 can be seamlessly adapted to the valve body assembly, thereby improving the sealing performance and the versatility of the water cup 10.

[0057] Compared to the circular water passage hole 21, the irregularly shaped mounting cavity 111 has a complex sealing structure, higher sealing process requirements, and is prone to local gaps due to vibration or aging, making it difficult to guarantee an effective seal. Therefore, this application provides a modified sealing element 20, with the water passage hole 21 formed inside the modified sealing element 20 connecting to the valve body assembly 30. This eliminates the need for the mounting cavity 111 to be directly connected to the valve body assembly 30, thereby changing the shape of the valve body assembly 30 and improving the sealing effect.

[0058] The drainage device provided in this application embodiment has a valve body assembly 30 that is closer to the mounting cavity 111 than the drain pump assembly 40. The valve body assembly 30 can effectively block the reverse flow of water from the water cup 10 to the drain pump assembly 40. The valve body assembly 30 can block the pipeline between the water cup 10 and the drain pump assembly 40, cut off the backflow path from the upstream of the water flow, and prevent the water flowing into the drain pump assembly 40 from flowing back into the water cup 10, further reducing the residual water in the water cup 10 and reducing the risk of pollution. In addition, with the suction of the drain pump assembly 40 itself, it helps to empty the water flowing from the water cup 10 into the drain pump assembly 40.

[0059] In one possible implementation method, refer to Figure 3 and Figure 4 As shown, the modified seal 20 can be connected to the mounting cavity 111 by interference fit or by snap-fit.

[0060] In one possible implementation method, refer to Figure 4 , Figure 5 and Figure 6 As shown, the modified seal 20 includes a skeleton part 22 and a sealing part 23. The skeleton part 22 includes a cylindrical body part 221 and an end panel 222. The end panel 222 is connected to the first end of the cylindrical body part 221. The water passage hole 21 includes a connecting hole 211 located in the cylindrical body part 221 and a clearance hole 212 located in the end panel 222. The connecting hole 211 and the clearance hole 212 are interconnected.

[0061] The sealing part 23 is provided on the skeleton part 22. The sealing part 23 is used to achieve the seal between the modified seal 20 and the mounting cavity 111. The sealing part 23 is also used to achieve the seal between the modified seal 20 and the mounting part 311.

[0062] The skeleton part 22 provides rigid functions such as support, impact resistance, and fixation, which helps to improve the structural stability of the modified seal 20. The sealing part 23 realizes the sealing function, so that the modified seal 20 has both a certain structural strength and good sealing performance.

[0063] In one possible implementation, the cylinder body 221 and the end panel 222 can be an integrally connected structure. The end panel 222 supports the first sealing part 231, which is used to achieve a seal between the mounting part 311 and the end panel 222. The water flowing out of the water cup 10 enters the valve body assembly 30 through the clearance hole 212. The first sealing part 231 can effectively prevent water from leaking between the mounting part 311 and the end panel 222.

[0064] In one possible implementation, the sealing portion 23 includes a first sealing portion 231 disposed on the side of the end panel 222 facing the connection hole 211 and surrounding the periphery of the clearance hole 212, and the mounting portion 311 extends into the connection hole 211 and abuts against the first sealing portion 231.

[0065] The first sealing part 231 is disposed on the side of the end panel 222 facing the connection hole 211 and surrounds the periphery of the clearance hole 212 to ensure the reliability of the seal.

[0066] In one possible implementation, the mounting section 311 has a water flow channel 312 communicating with the clearance hole 212.

[0067] In one possible implementation method, refer to Figure 2 , Figure 4 and Figure 6 As shown, the end of the mounting part 311 that extends into the connecting hole 211 has a sealing protrusion 3111. The sealing protrusion 3111 abuts against the first sealing part 231. The sealing protrusion 3111 can be arranged in a circle with the center line of the water flow channel 312 as the center.

[0068] When the mounting part 311 presses the first sealing part 231, the first sealing part 231 undergoes elastic deformation, and the sealing protrusion 3111 can also undergo elastic deformation, which improves the elastic buffering effect and can effectively prevent the end panel 222 from being crushed or damaged.

[0069] In one possible implementation, the sealing protrusion 3111 can be made of a flexible material, such as silicone or rubber.

[0070] In one possible implementation, the skeleton part 22 can be made of plastic, and the sealing part 23 can be made of soft rubber, such as silicone or rubber.

[0071] In one possible implementation, the skeleton part 22 and the sealing part 23 may be connected by mechanical engagement.

[0072] In another possible implementation, the skeleton part 22 and the sealing part 23 can be directly fused together through a secondary injection molding process, which helps to improve the stability of the modified seal 20 and prevent the sealing part 23 from loosening or falling off. In addition, it can reduce the manual assembly process, reduce the production cycle and cost, and at the same time reduce the number of parts and improve the consistency of the modified seal 20.

[0073] In one possible implementation method, refer to Figure 4 and Figure 12 As shown, the diameter of the mounting cavity 111 is larger than the diameter of the outlet 13, so that a step 113 is formed at the end of the mounting cavity 111 near the outlet 13.

[0074] In one possible implementation method, refer to Figure 4 , Figure 5 and Figure 6 As shown, the sealing part 23 also includes a second sealing part 232, which is embedded in the cylinder body part 221.

[0075] In one possible implementation, the second sealing portion 232 includes an outer sealing portion 2321 that extends to the outer side wall of the cylinder portion 221 and abuts against the inner peripheral side wall of the mounting cavity 111.

[0076] The outer sealing part 2321 seals the space between the inner circumferential sidewall of the cylinder body 221 and the mounting cavity 111, preventing water from leaking outward and preventing external air or impurities from entering through the gap between the cylinder body 221 and the inner wall of the mounting cavity 111. This protects the components from corrosion and prevents secondary pollution.

[0077] In one possible implementation, the outer sealing part 2321 conforms to the inner peripheral sidewall of the mounting cavity 111. The inner wall of the mounting cavity 111 and the skeleton part 22 compress the outer sealing part 2321, causing the outer sealing part 2321 to undergo elastic deformation, thereby filling the gap between the inner peripheral sidewall of the mounting cavity 111 and the skeleton part 22. This ensures that the water flowing out of the water cup 10 can only pass through the water passage hole 21 opened in the modified seal 20, and that the modified seal 20 is fixed in the mounting cavity 111.

[0078] In one possible implementation, the outer seal 2321 has a ridge 2323 that can extend along the axial direction or other directions of the modified seal 20. The ridge 2323 abuts against the inner peripheral sidewall of the mounting cavity 111, which can further improve the sealing performance.

[0079] In one possible implementation method, refer to Figure 4 , Figure 5 and Figure 12 As shown, the second sealing part 232 includes: end face sealing rib 2322, the end face sealing rib 2322 protrudes from the side of the end panel 222 opposite to the water passage hole 21, and the end face sealing rib 2322 abuts against the step 113, that is, the end face sealing rib 2322 abuts against the end face of the mounting cavity 111 near the water cup 10.

[0080] By setting the end face sealing rib 2322, a tight contact is formed between the end face sealing rib 2322 and the end face of the mounting cavity 111 near the water cup 10, filling any possible gaps and effectively preventing fluid leakage, thereby further improving the sealing effect. In addition, when the modified seal 20 is installed into the mounting cavity 111, the end face sealing rib 2322 plays a certain elastic buffering role, which can effectively protect the connector 11 of the water cup 10.

[0081] In one possible implementation, the second sealing portion 232 may consist only of the outer sealing portion 2321, or it may consist only of the end face sealing rib 2322. Of course, the second sealing portion 232 may also include both the outer sealing portion 2321 and the end face sealing rib 2322.

[0082] The second sealing part 232 and the first sealing part 231 achieve a double sealing effect, ensuring that water flows only through the water passage hole 21 of the modified seal 20, preventing residual water from flowing back.

[0083] In one possible implementation method, refer to Figure 2 , Figure 4 and Figure 6 As shown, the cylinder body 221 has a compression rib 2211, which is located on the inner wall of the connection hole 211. At least two compression ribs 2211 are arranged at intervals along the circumference of the connection hole 211. The compression ribs 2211 abut against the mounting part 311, or the compression ribs 2211 abut against the outer wall surface of the mounting part 311, thereby improving the connection stability of the mounting part 311 to the water passage hole 21.

[0084] In one possible implementation, the outer wall of the mounting portion 311 has at least two reinforcing ribs 3112, which extend along the axial direction of the mounting portion 311 and are arranged at intervals along the circumferential direction of the mounting portion 311.

[0085] In one possible implementation, the side wall of the modified seal 20 is provided with a drain hole 24, and the water passage 21 is connected to the communication port 112 through the drain hole 24. The drain hole 24 and the communication port 112 are positioned correspondingly.

[0086] In one possible implementation, the drainage device also includes a drainage pump assembly 40, which is connected to the connection port 112 via a water inlet pipe 60.

[0087] In one possible implementation method, refer to Figure 11 As shown, the connector 11 can be integrally connected to the water cup 10. The water cup 10 has a water storage cavity 12, which is interconnected with the mounting cavity 111. The water storage cavity 12 is the lowest point where water is stored inside the dishwasher. The drain hole 24 is used to prevent the modified seal 20 from obstructing the communication between the water storage cavity 12 inside the water cup 10 and the connecting port 112.

[0088] In one possible implementation, the drain hole 24 can be, but is not limited to, a circular hole, a rectangular hole, or an elliptical hole.

[0089] In one possible implementation method, refer to Figure 7 and Figure 8 As shown, the drainage pump assembly 40 includes a base 41 and a drainage pump body 42. The drainage pump body 42 is disposed on the base 41, and the base 41 has a water inlet 411 communicating with the drainage pump body 42. The water inlet 411 and the connecting port 112 are connected by a water inlet pipe 60. The water inlet pipe 60 serves to assist in fixing the drainage pump assembly 40 and to provide a drainage channel.

[0090] The drainage pump assembly 40 has a drain outlet 413, which is connected to the sewer pipe.

[0091] In one possible implementation, the main body 42 of the drainage pump can be connected to the base 41 by means of bolt fastening, snap-fit, or other means, and the base 41 provides stable support for the main body 42 of the drainage pump.

[0092] In one possible implementation, one end of the water inlet pipe 60 can be connected to the water inlet 411 by means of fasteners such as threaded engagement, screws, bolts, or snap-fit, and the other end of the water inlet pipe 60 can be connected to the connecting port 112 by means of fasteners such as threaded engagement, screws, bolts, or snap-fit, and a sealing ring is provided between the water inlet pipe 60 and the water inlet 411, and between the water inlet pipe 60 and the connecting port 112.

[0093] In one possible implementation method, refer to Figure 9 and Figure 10 As shown, the modified seal 20 is integrally connected to the connector 11 via secondary injection molding.

[0094] This structure eliminates the need for separate processing of the modified seal 20, making the modified seal 20 and the connector 11 an integral structure. This not only improves the stability of the modified seal 20 and prevents it from loosening or falling off, but also reduces the number of parts, which helps to reduce manual assembly steps, shorten the production cycle and cost, and improve the consistency of the modified seal 20. In addition, reducing the number of parts can also reduce sewage residue at the locations where multiple parts are combined.

[0095] In one possible implementation, the portion of plastic forming the connector 11 acts as the skeleton 22 of the modified seal 20, which can reduce the number of leakage points and improve the leak-proof effect.

[0096] In one possible implementation method, refer to Figure 7 As shown, the shape of the mounting cavity 111 is different from the shape of the water passage hole 21.

[0097] To facilitate the removal of large debris stuck in the dishwasher during drainage, a removable contaminant baffle is installed at the water outlet 13. The contaminant baffle can prevent large contaminants from accidentally entering the water outlet 13.

[0098] In one possible implementation, the contaminant baffle extends in the same direction as the water flow through the outlet 13, and the contaminant baffle has multiple filter meshes.

[0099] In one possible implementation, the valve body assembly 30 further includes a valve body 32 disposed on the mounting base 31.

[0100] In one possible implementation, the valve body 32 can be connected to the second end of the mounting base 31 by fasteners such as screws, bolts, or screws. Alternatively, it can be connected to the second end of the mounting base 31 by a snap-fit ​​mechanism.

[0101] In one possible implementation method, refer to Figure 7 and Figure 8 As shown, the drain pump assembly 40 is disposed on the outer wall of the water cup 10 via the connecting assembly 70.

[0102] In one possible implementation, the connecting assembly 70 includes: a first connector 71 and a second connector 72, the first connector 71 being disposed on the outer wall of the water cup 10 and including at least one first engaging portion 711; the second connector 72 being disposed on the outer wall of the drain pump assembly 40 and including at least one second engaging portion 721.

[0103] In one possible implementation, one of the first engaging portion 711 and the second engaging portion 721 is a claw, and the other of the first engaging portion 711 and the second engaging portion 721 is a slot, with the claw extending into the slot and flexibly engaging with it.

[0104] In one possible implementation, the first engaging portion 711 is a claw, and the second engaging portion 721 is a slot formed within the second connector 72. The claw extends into the slot and flexibly engages with it. The first connector 71 also includes a connecting body 712, to which the claw is fixed. The claw and the connecting body 712 can be an integrally connected structure.

[0105] In one possible implementation, the first connector 71 further includes a connecting body 712, which is a connecting block. The first engaging portion 711 is a slot formed inside the first connector 71, and the second engaging portion 721 is a claw extending out of the second connector 72. The claw extends into the slot and flexibly engages with the slot.

[0106] In one possible implementation, the connecting body 712 has a snap-fit ​​hole 7121, and the outer wall of the water cup 10 has a locking part 115. The locking part 115 is fastened in the snap-fit ​​hole 7121, thereby connecting the first connector 71 to the water cup 10.

[0107] The connecting component 70 not only enables the installation and positioning of the drain pump assembly 40, but also absorbs the mechanical vibration of the drain pump assembly 40 during operation, suppresses the vibration noise of the drain pump assembly 40, which helps to reduce the noise of the dishwasher during drainage and improve the user experience.

[0108] In one possible implementation, the connecting body 712 can be connected to the outer wall of the water cup 10 by fasteners such as screws or bolts, or it can be connected to the outer wall of the water cup 10 by a snap-fit ​​mechanism. Of course, the first connecting member 71 can also be an integral structure formed integrally with the water cup 10.

[0109] The second connector 72 is a flexible component. Through the elastic properties of the second connector 72, the drain pump assembly 40 is flexibly fixed. The elastic deformation of the second connector 72 can absorb the vibration energy of the drain pump assembly 40 during operation, thereby reducing the vibration and noise transmitted from the drain pump assembly 40 to the water cup 10.

[0110] In one possible implementation, the second connector 72 is a flexible component that can compensate for errors such as machining errors and misalignment during assembly through its own deformation. For example, the second connector 72 can be a single-material rubber or silicone component, or it can be a rubber or silicone component with embedded plastic parts.

[0111] In one possible implementation, the drain pump assembly 40 includes a base 41, one of which, the base 41, and the second connector 72, has a mating hole 722. The other of the base 41 and the second connector 72 is connected to a fixing post 412, which extends into the mating hole 722 and is flexibly connected to the mating hole 722.

[0112] In one possible implementation, a fixing post 412 is connected to the side of the base 41 facing the second connector 72. The second connector 72 has a mating hole 722. The fixing post 412 extends into the mating hole 722 and is flexibly connected to the mating hole 722.

[0113] In another possible implementation, the side of the second connector 72 facing the base 41 is connected to a fixing post 412, the base 41 has a mating hole 722, the fixing post 412 extends into the mating hole 722 and is flexibly connected to the mating hole 722.

[0114] In one possible implementation, the extension direction of the mating hole 722 is consistent with the extension direction of the slot.

[0115] This application also provides a dishwasher, including the aforementioned drainage device.

[0116] In one possible implementation method, refer to Figure 13 As shown, the dishwasher also includes an inner tank 80, with a water cup 10 located at the bottom of the inner tank 80.

[0117] When the dishwasher is draining, the water flow is gradually drawn from the inner tank 80 into the water storage chamber 12 of the water cup 10 under the suction of the drain pump assembly 40 and its own gravity. The water in the water storage chamber 12 of the water cup 10 flows from the outlet 13 through the mounting cavity 111 of the connector 11 and the water passage 21 of the modified seal 20 into the water flow channel 312 of the valve body assembly 30. The water flowing out of the valve body assembly 30 then flows through the drain hole 24 of the modified seal 20 and the connecting port 112 on the side wall of the connector 11 into the water inlet pipe 60. The water flowing into the water inlet pipe 60 flows along the water inlet pipe 60 to the water inlet 411 of the drain pump assembly 40, and is finally delivered to the drain outlet 413 of the drain pump assembly 40 and discharged into the sewer through the drain pipe 43.

[0118] The other structural features of the dishwasher are similar to those in the existing design and will not be described in detail here.
