DETAILED DESCRIPTION

[0060] Hereinafter, various embodiments of the present invention will be described more fully. The present invention may have various embodiments, and adjustments and changes may be made therein. However, it should be understood that there is no intention to limit the various embodiments of the present invention to the specific embodiments disclosed herein, but the present invention should be understood to cover all adjustments, equivalents and / or alternatives falling within the spirit and scope of the various embodiments of the present invention.

[0061] Example

[0062] like Figure 1-Figure 4As shown, this embodiment provides a sink dishwasher with a lifting support plate 2, which is suitable for installation in a kitchen. Specifically, its structure comprises a shell 4, a tank body 1, a tank cover 7, a lifting support plate 2, a lifting assembly, a spray arm 66 and a water supply system. The tank body 1 is embedded in the upper surface of the shell 4, the tank cover 7 is hinged to the top of the tank body 1 to open or close the tank body 1, the spray arm 66 is arranged in the tank body 1, the lifting assembly comprises a lifting rod group 36 for lifting, and the water supply system comprises a spray arm water supply pipeline 64 connected to the water inlet of the spray arm 66; the lifting rod group 36 is connected to the lifting support plate 2 located in the tank body 1 to drive the lifting support plate 2 to lift.

[0063] The housing 4 in this embodiment should be understood in a broad sense, including an open housing 4, a closed housing 4, and a housing 4 with accessories, and for example, the main body thereof is a square structure with a hollow hole space inside, and preferably has a cabinet door on the side.

[0064] In this embodiment, there are two use states. In the first state, the sink dishwasher with the lifting support plate 2 is used as a dishwasher. In the second state, the sink dishwasher with the lifting support plate 2 is used as a sink.

[0065] In the first state, the lifting support plate 2 is used to receive the bowl rack 65. The lifting support plate 2 is configured so that the fluid sprayed by the spray arm 66 can pass through the lifting support plate 2 and act on the bowl rack 65. The lifting rod group 36 rises so that the bowl rack 65 can be exposed from the upper surface of the tank body 1. The lifting rod group 36 falls so that the bowl rack 65 completely falls into the tank body 1 to close the tank cover 7 and start the spray arm water supply pipeline 64. In the second state, the lifting support plate 2 is used to receive the cutting board.

[0066] Since the sink dishwasher with the lifting support plate 2 is used as a sink in the second state, the water supply system also includes a faucet or a water supply port on the sink body 1, and a water supply pipeline connecting them. One or more drain ports on the sink body 1, drain pipes connecting the drain ports, and a valve for controlling the on-off of the drain pipe, preferably also have a pumping device to assist drainage.

[0067] In this embodiment, Figure 5 As shown, the lifting tray 2 has a plurality of flow holes 68 running through the upper and lower ends thereof, so that the fluid sprayed by the spray arm 66 can pass through the flow holes 68. For example, the lifting tray 2 is a grid structure composed of a plurality of cross-ribs and vertical ribs, or other types of structures with multiple flow holes 68. Since the flow holes 68 run through the upper and lower ends of the lifting tray 2, when a bowl rack 65 is placed on the lifting tray 2, the water sprayed by the spray arm 66 located below the lifting tray 2 can pass through, thereby washing the tableware on the bowl rack 65. When a cutting board is placed on the lifting tray 2, the juice and waste water that fall onto the lifting tray 2 can flow into the tank body 1 through the flow holes 68.

[0068] In this embodiment, Figure 5-Figure 8 As shown, the upper surface of the spray arm 66 has a plurality of nozzles 661, and the lower surface of the spray arm 66 has an annular water inlet 662 centered at the rotation axis of the spray arm 66. The spray arm water supply pipeline 64 includes a water supply pipe seat 67 fixed in the tank body 1, the water supply pipe seat 67 is inserted into the annular water inlet 662, the water supply pipe seat 67 includes an inner tube shell 70 and an outer tube shell 69, the gap between the inner tube shell 70 and the outer tube shell 69 forms the water outlet of the water supply pipe seat 67, and the outer tube shell 69 and the annular water inlet 662 are sealed by at least one sealing ring.

[0069] In this embodiment, the spray arm 66 and the water supply pipe seat 67 are sleeved on the lifting rod group 36, and there is a gap between the spray arm 66 and the lifting rod group 36, so that the spray arm 66 can rotate around the lifting rod group 36 under the drive of the water flow supplied by the water supply pipe seat 67. Driven by the water flow, the spray arm 66 sprays water upward and rotates around the lifting rod group 36 at the same time, so that water can be sprayed from multiple positions to achieve uniform cleaning of the tableware.

[0070] In this embodiment, a return water pipeline 63, a circulation pump 62 and a water tank 61 are also included. The return water pipeline 63 is connected to the drain outlet at the bottom of the tank body 1. The circulation pump 62 is arranged between the spray arm water supply pipeline 64 and the return water pipeline 63, and is used to deliver the water flow discharged from the drain outlet at the bottom of the tank body 1 to the spray arm 66 again. The water tank 61 is connected to the circulation pump 62, and is used to supply the water source in the water tank 61 to the spray arm 66. Specifically, a pump and a valve are arranged in the circulation pump 62, and the valve controls the connection and disconnection between the circulation pump 62 and the water tank 61, and the connection and disconnection between the spray arm water supply pipeline 64 and the return water pipeline 63. The pump draws water from the water tank 61 or the return water pipeline 63 and supplies it to the spray arm water supply pipeline 64 under positive pressure.

[0071] The lifting assembly 3 also includes a lifting drive device 41 and a lifting base 35. The lifting base 35 is installed in the housing. The lifting drive device 41 and the lifting rod group 36 are respectively installed on the lifting base 35. The lifting drive device 41 drives and connects the lifting rod group 36 to lift the lifting rod group 36. The lifting rod group 36 passes through the trough body 1 from the bottom and connects to the support plate 2 located in the trough body 1. Among them, the lifting drive device 41 is composed of a motor, a speed regulating box 40, a rotating shaft and other structures. The rotation output by the motor is regulated by the speed regulating box 40 and then transmitted to the lifting rod group 36 by the transmission shaft. For example, there are mutually meshing gears between the lifting rod group 36 and the rotating shaft, and the gear transmission is carried out.

[0072] When the multifunctional food and tableware washing platform is in use, when food needs to be processed, such as cutting vegetables, the lifting drive device 41 can be activated to automatically raise the support plate 2, and the user can directly place the cutting board on the support plate 2, and then process the food. During the processing of the food, the food debris that falls off the cutting board falls onto the support plate 2 or into the tank body 1. When the food does not need to be processed anymore, the user can control the lifting drive device 41 to automatically lower the support plate 2 back to the bottom of the tank, and the tank body 1 can be used as a regular sink.

[0073] like Figure 3-Figure 5 As shown, the lifting rod group 36 includes a screw rod and a movable sleeve, the screw rod is rotatably mounted on the lifting base 35, the power output end of the lifting drive device 41 is threadedly matched with the screw rod, the movable sleeve is arranged outside the screw rod and the two are threadedly matched, and the top of the movable sleeve is connected to the support plate 2. Due to the threaded match between the screw rod and the movable sleeve, during the lifting process, the motion control accuracy is high, the operation is stable, and it has a self-locking function, so that the lifting support plate can be kept in position when the lifting drive device is not started.

[0074] like Figure 5 As shown, a dynamic sealing device is provided between the lifting rod group 36 and the tank body 1 .

[0075] Figure 9-12 A preferred dynamic sealing device 5 is shown. Specifically, the dynamic sealing device 5 includes a sealing buckle cover 51, an inner sealing ring 53 and a hollow stud 56. An annular sealing tongue 510 of the sealing buckle cover is formed on the radial inner wall of the sealing buckle cover 51. Specifically, the number of the annular sealing tongue 510 of the sealing buckle cover is one or more. In addition, the annular sealing tongue 510 of the sealing buckle cover is preferably an integrated structure with the body of the sealing buckle cover 51. The sealing buckle cover 51 also has an internal thread section that is threadedly matched with the hollow stud 56. The inner sealing ring 53 is sleeved in the hollow stud 56, and an annular sealing tongue 54 of the inner sealing ring is formed on the radial inner wall of the inner sealing ring 53. One end face of the inner sealing ring 53 is encapsulated in the sealing buckle cover 51, and the other end face is encapsulated in the hollow stud 56.

[0076] The annular sealing tongue 510 of the sealing buckle cover is one or more annular sealing tongues, and the annular sealing tongue 54 of the inner sealing ring is one or more annular sealing tongues. The annular sealing tongue 510 of the sealing buckle cover is preferably an O-type sealing rubber ring or other structures, and the annular sealing tongue 54 of the inner sealing ring is preferably an annular elastic sealing sleeve, and the surface contacting the shaft component is preferably an inclined surface.

[0077] According to the dynamic sealing device 5 in this embodiment, the radial inner wall of the sealing buckle cover 51 is formed with an annular sealing tongue 510 of the sealing buckle cover, and the annular sealing tongue 510 of the sealing buckle cover forms the first seal for the shaft-like components, so that the fluid in the tank body 1 cannot leak from between the sealing buckle cover 51 and the shaft-like components. When the annular sealing tongue 510 of the sealing buckle cover is broken and needs to be replaced, it only needs to rotate the sealing buckle cover 51 to replace it, which is more convenient to replace. In addition, since the radial inner wall of the inner sealing ring 53 is formed with an annular sealing tongue 54 of the inner sealing ring, it can work together with the annular sealing tongue 510 of the sealing buckle cover to form multiple seals, which significantly improves the sealing effect. Compared with the prior art, even if the annular sealing tongue 510 of the sealing buckle cover is partially damaged, the annular sealing tongue 54 of the inner sealing ring can still prevent fluid leakage under the sealing effect of the annular sealing tongue 54 of the inner sealing ring. Moreover, when it is necessary to replace the annular sealing tongue 54 of the inner sealing ring, it is only necessary to rotate the sealing buckle cover 51 to separate it from the shaft-like components to replace the annular sealing tongue 54 of the inner sealing ring, which is very convenient.

[0078] In this embodiment, an elastic ring 59 is fixed to the radial outer side of the annular sealing tongue 54 of the inner sealing ring, and the elastic ring 59 includes an annular spring or an annular elastic rubber ring, preferably a spring. Since an elastic ring 59 such as a spring is fixed to the radial outer side of the annular sealing tongue 54 of the inner sealing ring, under the elastic force constraint of the elastic ring 59, the annular sealing tongue 54 of the inner sealing ring has a stronger lasting elastic deformation ability, and even if used for a long time, the annular sealing tongue 54 of the inner sealing ring can still be in close contact with the shaft components, further making the dynamic sealing device 5 have a long-term sealing performance.

[0079] In this embodiment, the inner sealing ring 53 is formed with an annular groove 55 on the radial outer side of the annular sealing tongue 54 of the inner sealing ring, which is particularly suitable for the case where the number of the annular sealing tongue 54 of the inner sealing ring is one. Since the inner sealing ring 53 is formed with an annular groove 55 on the radial outer side of the annular sealing tongue 54 of the inner sealing ring, the annular groove 55 can provide space for the elastic deformation of the annular sealing tongue 54 of the inner sealing ring, so that the annular groove 55 has a larger elastic deformation capacity, and on the other hand, the annular groove 55 is convenient for accommodating the elastic ring 59 on the radial outer side of the annular sealing tongue 54 of the inner sealing ring.

[0080] Furthermore, the dynamic sealing device 5 further includes a locking nut 52, and the hollow stud 56 includes a first external thread section 57 and a second external thread section 58, the first external thread section 57 is threadedly matched with the internal thread section of the sealing buckle cover 51, the diameter of the second external thread section 58 is smaller than the diameter of the first external thread section 57, and the locking nut 52 is threadedly matched with the second external thread section 58. Since the dynamic sealing device 5 further includes a locking nut 52, and the hollow stud 56 includes a first external thread section 57 and a second external thread section 58, the gap between the locking nut 52 and the step surface of the hollow stud 56 can be used to install and lock the tank body 1 such as the water tank. Specifically, the wall of the tank body 1 is sleeved on the second external thread section 58, and the locking nut 52 is rotated to lock the wall of the tank body 1.

[0081] When the dynamic sealing device 5 does not include the locking nut 52, the bottom of the tank body 1 is fixedly connected to the outer surface of the hollow stud 56 or the sealing buckle cover 51. When the dynamic sealing device 5 includes the locking nut 52, the bottom of the tank body 1 is sleeved on the second external thread section 58, and the locking nut 52 can be rotated to lock the wall of the tank body 1, so that the entire dynamic sealing device 5 and the tank body 1 are completely detachably connected, which is convenient for maintenance and replacement of all parts of the dynamic sealing device 5.

[0082] like Fig.13 As shown, it also includes a multifunctional integrated storage rack, which is fixed on the shell, and the height of the multifunctional integrated storage rack is greater than the height of the shell. In this way, the space above the shell can be more fully utilized, and the storage space, food and tableware cleaning and processing functions can be integrated.
