Description

Technical Field

[0001] This utility model relates to the field of kitchen waste recycling technology, and in particular to a blade structure at the bottom of the mixing drum of a kitchen waste shredder. Background Technology

[0002] In order to accelerate the efficiency of food waste processing, small-scale food waste recycling equipment must chop the input food waste to make the food waste particles smaller. For example, in the waste crushing and processing device of Taiwan Patent No. 303732, when waste is placed from the top of the guide trough, the inclined plate can guide the waste to the drum, and the rotation of the drum moves the waste to the junction of the drum and the blade: at this time, the cutting edge of the blade tip protrudes from the outer edge of the drum and intersects with the serrated edge of the blade to cut the waste.

[0003] In the previous design, the blade was a single piece, which was expensive to manufacture. It needed to be locked inside the roller and interact with the blade to achieve the cutting purpose.

[0004] In addition, kitchen waste such as rice and rice porridge contains a high amount of starch. After heating and stirring, the starch granules will swell and break down, forming gelatin. This causes the starch to become a gelatinous or highly viscous form (such as mochi or paste). This is because when the amylopectin and amylose in starch are heated and absorb water, the higher the amylopectin content, the stronger the viscosity after gelatinization.

[0005] This increases the load (resistance) on the mixing equipment during the recycling process, and in severe cases, it can even cause the mixing equipment to jam. Therefore, there is a real need to improve the current food waste recycling equipment in terms of blade replacement convenience, maintenance costs, and the ability to cut gel-like or highly viscous food waste. Utility Model Content

[0006] In view of the problems and deficiencies of the prior art, the main objective of this utility model is to provide a blade structure at the bottom of the mixing drum of a food waste grinder, which solves the problems of the prior art through innovative structural design.

[0007] According to the aforementioned objective of this utility model, this utility model discloses a bottom blade structure for a food waste disposer's mixing drum, comprising a housing, a mixing drum, a plurality of blades, and a mixing device. The housing has an internal accommodating space and a top opening at the top. The mixing drum, assembled and disposed within the accommodating space, has an upper groove communicating with the top opening, and a plurality of positioning holes are formed through the inner wall of the mixing drum, penetrating the wall and disposed at the bottom of the mixing drum. Each positioning hole group includes two positioning holes arranged at intervals. The plurality of blades, corresponding to the matching positioning hole groups, are disposed in the mixing drum and have at least one cutting edge, disposed at one end of the blade's extension direction. The mixing device, pivotally connected to the housing and disposed within the mixing drum, includes a shaft pivotally connected to the housing at both ends; a plurality of lever arms are sleeved on the outer periphery of the shaft and move with it, wherein each lever arm has a plurality of recessed grooves at its end for the blades to pass through.

[0008] Furthermore, each of these levers is configured in an X-shape.

[0009] Furthermore, the blade has a plurality of positioning pins extending outward from the bottom end of the blade and inserted into each of the matching positioning hole groups.

[0010] By using the above components, the blades can be assembled in an independent manner, which facilitates subsequent maintenance and replacement, and further enhances the blade's ability to cut food waste. Attached Figure Description

Various components in the embodiments are depicted according to the applicable scale, dimensions, deformation, or displacement, rather than being drawn to scale with actual components; this is stated prior to the description. Furthermore, components with identical or symmetrical arrangements in the remaining embodiments are represented by the same numbers. Additionally, directional terms such as "front," "back," "left," "right," "up," "down," "inner," and "outer" in the descriptions of the embodiments listed below are used according to the specified view direction and should not be construed as limiting the scope of this utility model.

[0019] Please see Figures 1 to 7 As shown, the bottom blade structure of the mixing drum of the kitchen waste shredder of this utility model includes a housing 10, a mixing drum 20, a plurality of blades 30 and a mixing device 40.

[0020] The aforementioned housing 10 has an accommodating space 11 and a top opening 12.

[0021] The accommodating space 11 is formed inside the housing 10.

[0022] A top opening 12 is formed on the top of the housing 10, connecting the accommodating space 11 and the outside of the housing 10.

[0023] The aforementioned stirring cylinder 20 is assembled at a preset location in the housing 10 and disposed in the accommodating space 11, and has an upper slot 21 and a plurality of positioning holes 22.

[0024] The upper groove 21 is formed at the top of the mixing drum 20 and connects to the top opening 12 of the casing 10.

[0025] Each group of positioning holes 22 is formed by penetrating the wall of the mixing cylinder 20 and is disposed at the bottom of the mixing cylinder 20. Each group of positioning holes 22 is arranged in a spaced-out manner with two positioning holes 221 as a group.

[0026] During implementation, the positioning holes 221 can be formed by laser cutting or punching when the wall of the mixing drum 20 has not yet been bent (i.e., in the state of the plate), ensuring their accuracy.

[0027] Each of the aforementioned blades 30 has a corresponding set of positioning holes 22 located inside the stirring cylinder 20. It has a plurality of positioning posts 31 and at least one cutting edge 32.

[0028] Each positioning post 31 extends outward from the bottom end of the blade 30 and is inserted into the matching positioning hole group 22.

[0029] The cutting edge 32 is formed on two sections in the extending direction of the blade 30.

[0030] The aforementioned stirring device 40 is pivotally connected to the housing 10 and disposed in the stirring drum 20, and includes a shaft 41 and a plurality of lever arms 42.

[0031] Shaft 41 has a preset length and is pivotally connected to housing 10 at both ends.

[0032] Each lever arm 42 is respectively sleeved on the outer periphery of the shaft 41 and moves together with it, and as... Figure 6 The configuration shown is X-shaped. The lever 42 has a plurality of toothed grooves 422.

[0033] The aforementioned toothed grooves 422 are recessed at both ends of the cross section in the extending direction of the lever arm 42, providing for the penetration of each blade 30. Therefore, the above is a preferred embodiment of the present invention, describing the structure of the blade at the bottom of the mixing drum of the food waste shredder, the components and the assembly method. The operating features of the embodiment of the present invention will be described below. By having the blades 30 independently and individually set in each positioning hole group 22 (positioning hole 221), not only is assembly easier, but the accuracy of the blade position is also ensured, avoiding obstruction with the stirring device 40.

[0034] Furthermore, when any blade 30 is damaged, it can be repaired by replacing the individual blade 30, thereby reducing the maintenance cost and difficulty of replacement. In addition, when the paddles 42 of the mixing device 40 move the food waste in the mixing drum 20, they force the food waste to come into contact with the blade 32 of the blade 30, so that the blade 32 cuts the food waste, thus preventing the food waste in a gel-like or highly viscous form from tangling together and causing the mixing device 40 to be under a lot of stress.

[0035] The above description is only a preferred embodiment of the present utility model and is intended to clarify the features of the present utility model. It is not intended to limit the scope of the embodiments of the present utility model. Equivalent changes made by those skilled in the art based on the present utility model, as well as changes known to those skilled in the art, should still fall within the scope of the present utility model.
