These storage racks have various shapes and are used to place knives, bowls and chopsticks, cutting boards, etc. The left vertical frame 27 and the right vertical frame 28 are connected by at least one horizontal frame 29, and each storage rack is distributed on the left vertical frame 27, the right vertical frame 28 or the horizontal frame 29.

[0083] like Fig.15 As shown, the housing 4 is provided with a cabinet door 6 and a multi-unit compartment 33, and the multi-unit compartment 33 is detachably installed in the housing 4. The multi-unit compartment 33 includes a plurality of storage compartments or drawers, and the openings of the storage compartments face the cabinet door.

[0084] Preferably, a human-machine display control interface or a mechanical operation transmission system is provided on the housing 4, and the human-machine display control interface or the mechanical operation transmission system is used to control various functional components in the combined structure. The human-machine display control interface is also used to display preset target information, and the target information includes recipes, ingredients and cleaning methods of utensils.

[0085] Preferably, if Figure 5 , Figure 6As shown, the operating table 2 has drainage holes 20 running through the upper and lower ends thereof. Preferably, a drainage groove 19 is provided on the upper surface of the operating table 2, and the drainage groove 19 is connected to the drainage hole 20. Preferably, a filter box 21 is also included, and the filter box 21 is detachably installed in the drainage hole 20, and a plurality of filter holes are provided on the filter box 21. When in use, the juice and waste water falling onto the operating table 2 flows into the sink through the drainage hole 20, and the drainage groove 19 guides the juice and waste water on the upper surface of the operating table 2 to the drainage hole 20, and the detachable filter box 21 can collect the residues and debris entering the drainage hole 20.

[0086] like Figure 5 , Figure 6 As shown, the lower surface of the operating table 2 is provided with a plurality of support columns 18 for contacting the bottom of the water tank. Thus, the operating table 2 can not only be independently supported on the bottom of the tank, but also form a mechanical limit structure for the lifting assembly 3 using the support columns 18 to improve safety.

[0087] like Figure 5 , Figure 6 As shown, the outer periphery of the upper surface of the operating table 2 has an elastic ring 34, which is preferably a silicone ring, and the elastic ring 34 abuts against the inner wall of the sink. When in use, the elastic ring 34 fills the gap between the outer periphery of the operating table 2 and the inner wall of the sink, preventing food or other objects on the operating table 2 from falling from the outer edge of the operating table 2.

[0088] Preferably, the upper surface of the elastic ring 34 has at least one annular groove 22 surrounding the operating table 2. When in use, the annular groove 22 is provided so that the food moving to the edge of the operating table 2 is collected in the annular groove 22, so as to prevent the food from falling from the gap between the elastic ring 34 and the inner wall of the water tank due to the possible deformation of the elastic ring 34 during the lifting and lowering of the operating table 2. In addition, the food collected in the annular groove 22 is also convenient for centralized cleaning of the food.

[0089] like Figure 5 , Figure 6As shown, the upper surface of the operating table 2 has a plurality of air holes or air grooves 23, which are used for bonding between the plate and the operating table 2 when a plate is placed on the operating table 2. For example, the air holes are a plurality of small holes distributed in an array, and the size only needs to be larger than that of the plate to be easily stored. The air grooves 23 have various forms, such as arc grooves, annular grooves, etc. When the user places the cutting board on the operating table 2 to process food, due to the water droplets on the washed food and the relatively dampness of the operating table 2 itself after being soaked in the water tank, when the existing cutting board contacts the operating table 2, the two are easily closely adsorbed, making it difficult for the user to take away the cutting board or adjust the position of the cutting board on the operating table 2. In this embodiment, since the upper surface of the operating table 2 has a plurality of air holes or air grooves 23, these air holes or air grooves 23 can store air, so as to avoid the air between the cutting board and the operating table 2 being emptied by water to produce an atmospheric pressure difference, and the user can take and place the cutting board or adjust the position of the cutting board on the operating table 2 with great effort.

[0090] like Figure 3 As shown, a dynamic sealing device is provided between the lifting rod group 36 and the water tank.

[0091] Figure 7-Figure 11 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.

[0092] 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.

[0093] 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. The annular sealing tongue 510 of the sealing buckle cover forms the first seal for the shaft component, so that the fluid in the water tank cannot leak from between the sealing buckle cover 51 and the shaft component. 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 component to replace the annular sealing tongue 54 of the inner sealing ring, which is very convenient.

[0094] 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.

[0095] 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.

[0096] 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 a locking water tank such as a water tank. Specifically, the water tank wall is sleeved on the second external thread section 58, and the locking nut 52 is rotated to lock the water tank wall.

[0097] When the dynamic sealing device 5 does not include the locking nut 52, the bottom of the water tank is fixedly connected to the hollow stud 56 or the outer surface of the sealing buckle cover 51. When the dynamic sealing device 5 includes the locking nut 52, the bottom of the water tank is sleeved on the second external thread section 58, and the locking nut 52 can be rotated to lock the water tank wall, so that the entire dynamic sealing device 5 and the water tank are completely detachably connected, which is convenient for maintenance and replacement of all parts of the dynamic sealing device 5.

[0098] Example 2

[0099] This embodiment provides a tank cover capable of expanding the surface space of the upper cavity of a tank and a combined structure thereof with the tank, which is suitable for installation in a kitchen. Compared with the first embodiment, the difference of this embodiment is:

[0100] like Figure 18-Figure 20 As shown, the tank cover and its combined structure with the water tank in this embodiment do not have a lifting component, but there are multiple pairs of matching retaining structures between the inner wall of the water tank and the operating table 2, so that the operating table 2 can be detachably held horizontally in the water tank.

[0101] Preferably, the holding structure includes a column 42 connected to the side wall of the operating table 2 and a positioning groove 43 located on the inner wall of the water tank. When the column 42 is supported in the positioning groove 43, the operating table 2 is held horizontally. Specifically, for a rectangular operating table, two parallel side walls of the operating table 2 are provided with columns 42, and each side wall is provided with two or more columns 42. The inner wall of the water tank has a positioning groove 43 corresponding to each column 42. The positioning groove 43 can be directly formed on the inner wall of the water tank, or can be formed by a protrusion formed on the surface of the inner wall of the water tank.

[0102] like Fig.19 , Fig. 20 As shown, the positioning groove 43 has a plurality of positioning areas of different heights, so that the level of the operating table 2 in the water tank can be adjusted. For example, the positioning groove 43 has two positioning areas of different heights.

[0103] When it is necessary to process food, such as cutting vegetables, the column 42 of the side wall of the operating table 2 can be positioned in the positioning groove 43, so that the operating table 2 is horizontally supported above the bottom of the sink, and the user can directly place the cutting board 44 on the operating table 2, and then process the food. During the processing of food, the food debris that falls off the cutting board 44 falls on the operating table 2 or into the sink. Compared with the prior art, it can save the time required for placing the cutting board 44 to process food in the kitchen, and prevent the food that falls off the cutting board 44 from dirtying the stove or the ground. When it is no longer necessary to process food, the user can take away the operating table 2, and the sink can be used as a regular sink.
