Description

Technical Field

[0001] This utility model relates to the field of cooking appliance technology, and in particular to a steaming pot with a stable and rapid lifting filter plate structure. Background Technology

[0002] A lifting steamer is a cooking appliance with a liftable filter for separating food and broth. For example, patent number CN213963005U discloses a filter plate for a lifting rice cooker. In this type of side-lifting steamer, because the support point is on one side, the filter plate cannot be properly fixed inside the pot body. During use, the filter plate is prone to center of gravity shifting, resulting in food not being perfectly separated during steaming. To address this, a fixing post is set on one side of the filter plate, and a ball bearing is installed at the top of the fixing post to achieve a side support effect that prevents the filter plate from swaying. This lifting steamer has the following disadvantages:

[0003] 1. It uses a single lifting rod to make the filter disc move up and down with the lifting block. During the lifting process, the lifting block will tilt and sway. The screw below the lifting rod is a single thread screw, which has poor speed for the lifting rod to move up and down.

[0004] 2. The ball bearing is embedded in the fixed limiting post. During the cooking process, soup and water can easily accumulate and seep into the fixed limiting post. The internal structure of the ball bearing and the fixed limiting post is difficult to clean. In addition, the fixed limiting post needs to be installed on the filter plate by pressing and welding the ball bearing. After assembly and welding, it also needs to be polished and ground, making the production process relatively complicated.

[0005] Therefore, further improvements are needed. Utility Model Content

[0006] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention proposes a cooking pot with a stable and rapid lifting filter plate structure.

[0031] Example

[0032] Reference Figures 1 to 3 The present invention proposes a cooking pot with a stable and rapid lifting filter plate structure, including a base, a pot body and a filter plate assembly 10, and a lifting component 20 for lifting and moving the filter plate assembly 10 is provided on one side of the base.

[0033] The filter disc assembly 10 includes a filter disc body 11 and a lifting block 13; the lifting assembly 20 includes a lifting motor 21, a lead screw 22, a lifting rod 23, and a lifting seat 24; there are two lifting rods 23, located at opposite ends of the lifting seat 24; a screw hole 241 is provided in the center of the lifting seat 24; the lower part of the lead screw 22 is connected to the lifting motor 21, and the upper part is threadedly connected to the screw hole 241 of the lifting seat 24; two placement slots 131 are provided below the lifting block 13; the two placement slots 131 can be respectively fitted onto the upper part of the two lifting rods 23; the threads of the lead screw 22 and the lifting seat 24 are multi-start threads.

[0034] In this invention, two lifting rods 23 are matched with two placement slots 131 of the lifting block 13, providing lifting support at two points. This makes the lifting process of the lifting block 13 and the filter disc body 11 more stable and reliable, and less prone to shaking. Furthermore, by adopting a multi-threaded lead screw 22 structure, the lifting base can still move up and down stably and quickly during the rotation of the lead screw 22 with a large lead span, achieving the effect of stable and rapid lifting and lowering of the lifting block 13 and the filter disc body 11.

[0035] In this embodiment, after testing, in order to achieve relatively stable rapid movement and a high support effect, the number of spiral grooves of the lead screw 22 is greater than or equal to 3, the multi-start thread lead of the lead screw 22 is greater than 12mm, the pitch is greater than 3mm, and the multi-start thread bore diameter of the lead screw 22 is greater than 6mm.

[0036] Preferably, based on the cooking capacity requirements of cookware commonly used in the market, the multi-start thread of the lead screw 22 has 4 helical grooves, a lead of 13.2 mm, a pitch of 3.3 mm, and a multi-start thread bore diameter of 9.7 mm. For example, an M9.7x13.2 / (p3.3) multi-start lead screw 22 and thread can be used.

[0037] In this embodiment, the filter plate assembly 10 further includes a connecting pipe 12; the lifting block 13 is detachably placed above the lifting assembly 20; the connecting pipe 12 is bent into a "U" shape, welded to the filter plate body 11 at the bottom and installed on the lifting block 13 at the top; a protruding bent portion 121 protruding outward is provided at the bottom of the connecting pipe 12; a ball bearing 14 passes through the protruding bent portion 121; a gap is provided between the protruding bent portion 121 and the filter plate body 11; the ball bearing 14 can abut against the inner wall of the pot.

[0038] In this embodiment, the connecting pipe 12 is bent into a "U" shape and welded to the filter plate body 11 at the bottom, providing stable support on both sides of the filter plate body 11. The welding connection is minimal, requiring only grinding on the inner side of the filter plate for quick polishing. A raised, outwardly protruding bent portion 121 is provided below the connecting pipe 12. A ball bearing 14 passes through the raised bent portion 121, allowing it to roll against the inner wall of the pot, achieving a lateral support effect that prevents the filter plate from swaying. Furthermore, a gap is provided between the raised bent portion 121 and the filter plate body 11, allowing for convenient and direct rinsing and cleaning of the connecting pipe 12 and the ball bearing 14, preventing the accumulation of residual soup or dirt.

[0039] In this embodiment, in order to reduce the phenomenon of ball 14 sliding and wobbling along the connecting pipe 12, limit stops 122 are provided on both sides of the protruding bend 121, and ball 14 is located between the two limit stops 122.

[0040] Specifically, the limiting stop 122 is formed by integrally stamping a block or annular rib on the protruding bent part 121. In the production process, the ball 14 is first inserted into the connecting pipe 12, and then a block or annular rib is stamped at the protruding bent part 121. After that, it is welded to the filter disc body 11 to complete the assembly and limiting of the ball 14.

[0041] In this embodiment, in order to protect the lifting assembly 20, a lifting protective cover 25 is provided on the outside of the lifting rod 23.

[0042] In this embodiment, the lifting block 13 is provided with a handle to facilitate lifting the filter disc assembly 10 from the lifting assembly 20.

[0043] Of course, this utility model is not limited to the above-described embodiments. Those skilled in the art can make equivalent modifications or substitutions without departing from the spirit of this utility model. All such equivalent modifications and substitutions are included within the scope defined by the claims of this application.
