Meat grinder structure

Abstract

To provide a structure of a meat grinder. [Solution] The structure of the meat grinder 1 is primarily connected by a locking unit A between the intermediate shaft 21 of the fixed blade 22 and the support post 23 at the lower end of the intermediate shaft. The bottom of the meat grinder bowl 30 is concave and has a receiving concave surface. The receiving concave surface is embedded in the lower end of the support shaft and serves as a support point for the lower end of the intermediate shaft when it is rotated. With this configuration, even if the intermediate shaft and support shaft need to be made of different materials due to different functional requirements, the installation of a locking unit allows the intermediate shaft and support shaft to be combined and rotated together. By providing a circular receiving concave surface on the inner bottom surface of the meat grinder bowl, the lower end of the support shaft is embedded as a rotation fulcrum, eliminating the need for a support shaft or magnetic connection element in the meat grinder bowl. This makes the meat grinder bowl easy to clean, stackable with food containers, and microwaveable.

Description

[Technical Field]

[0001] The present invention relates to a meat grinder structure, and in particular to a meat grinder bowl that has no support shaft, is easy to clean, is odor-resistant, stackable, dishwasher-safe, and can be placed directly in a microwave oven for microwave cooking. [Background technology]

[0002] A conventional meat grinder primarily consists of a drive mechanism, a meat grinding blade assembly, and a meat grinding bowl. The drive mechanism is housed in a housing and includes a motor and associated control circuitry. The drive mechanism is connected to the meat grinding blade assembly, allowing it to rotate in a predetermined position. The top of the meat grinding bowl is connected to the bottom end of the housing, and a support shaft protruding upward from the center of the inner bottom surface of the meat grinding bowl is pivotally connected to the bottom of the meat grinding blade assembly and supports the lower end of the meat grinding blade assembly. This allows the meat grinding blade assembly to rotate smoothly and stably. This structure is shown in Figure 1 of Japanese Utility Model Registration No. 3247714 filed by the applicant. Summary of the Invention [Problem to be solved by the invention]

[0003] In use, a block of meat is placed in the meat grinder bowl 30 and the drive mechanism 10 rotatably drives the grinder blade assembly 20 to continuously cut the meat and form minced meat.

[0004] In the above-mentioned conventional meat grinder structure, the support shaft in the center of the meat grinder bowl makes cleaning inconvenient. In addition, the presence of the support shaft causes looseness when stacking meat grinder bowls and other bowls, occupying space, so improvements are needed. [Means for solving the problem]

[0005] In light of this situation, the inventor devised Japanese Utility Model Patent No. JPB-3247714U. The support shaft inside the meat grinder bowl is removed, and the lower end of the meat grinder blade assembly is fixed to the center of the bowl using a magnetic coupling. This eliminates the obstruction of the support shaft inside the meat grinder bowl, making cleaning and stacking easier. However, because a metal or magnetic material is fixed to the center of the meat grinder bowl, the meat grinder bowl cannot be placed in a microwave oven and heated directly. The ingredients in the meat grinder bowl must be transferred to a separate microwave-safe container before heating, which is extremely inconvenient.

[0006] Therefore, the inventor of this invention made several improvements to the design and arrived at the present invention.

[0007] Therefore, the main objective of the present invention is to provide a meat grinder bowl structure without a support shaft and magnetic connecting elements within the meat grinder bowl, so that the meat grinder bowl can be easily cleaned, stacked, and used in a microwave oven.

[0008] The main feature of this invention is that the intermediate shaft, which secures the blades, is connected to the support at its lower end by a locking unit. The lower end of the inner surface of the meat grinder bowl is concave and has a receiving recess. The lower end of the support shaft is fitted into this receiving recess, which serves as a fulcrum for the lower end of the intermediate shaft when it is rotated. With this configuration, even if the intermediate shaft and the support shaft need to be made of different materials due to different functional requirements, the installation of a locking unit allows the intermediate shaft and the support shaft to be combined and rotated together. By providing a circular receiving recess on the inner bottom surface of the meat grinder bowl, the lower end of the support shaft is embedded as a rotation fulcrum, eliminating the need for a support shaft or magnetic connection element in the meat grinder bowl. This makes the meat grinder bowl easy to clean, stackable with food containers, and directly microwaveable.

[0009] The technical means and structure adopted by the present invention to achieve the above objects and effects will be described below with reference to the following embodiments and accompanying drawings. [Effects of the Invention]

[0010] From the above description, it can be seen that the present invention has at least the following advantages and effects: 1. The intermediate shaft 21 and the support pillar 23 have different functional requirements and therefore need to be made of different materials. However, by providing lock unit A, the intermediate shaft 21 and the support pillar 23 can be combined and rotated together. 2. The inner bottom surface of the meat grinder bowl 30 is provided with a circular receiving recess 31 that forms a recess into which the lower end 230 of the support 23 is inserted, and functions as a pivot point between the intermediate shaft 21 and the support 23. This eliminates the need to provide a support shaft or magnetic connecting element within the meat grinder bowl 30, making the meat grinder bowl easier to clean, easier to stack with other appliances, and directly suitable for microwave heating.

[Figure 5] FIG. 5 is a top view of the present invention taken along the line 5S-5S in FIG. 2 . DETAILED DESCRIPTION OF THE INVENTION

[0012] In order to better understand the features and technical contents of the present invention, reference should be made to the following detailed description of the present invention and the accompanying drawings, which are provided for reference and explanation, and are not intended to limit the present invention.

[0013] 1 to 3, the meat grinder 1 of this embodiment mainly includes a drive mechanism 10, a meat grinding blade assembly 20, and a meat grinder bowl 30.

[0014] Drive mechanism 10 is enclosed in housing 11 and contains motor 12 and associated control circuitry.

[0015] As shown in FIG. 3, the meat grinder blade assembly 20 includes an intermediate shaft 21 and blades 22 fixed at upper and lower positions around the circumference of the intermediate shaft 21. The upper end of the intermediate shaft 21 is connected to the drive mechanism 10. When the motor 12 starts, the intermediate shaft 21 is driven to rotate at high speed. The lower end of the intermediate shaft 21 is connected to a support 23 via a locking unit A. The lower end 230 of the support 23 has an arcuate surface. The intermediate shaft 21 can be made of a non-toxic, high-temperature-resistant polypropylene (PP) material, and the support 23 can be made of a wear-resistant polyformaldehyde (POM) material. The locking unit A is formed by a table 231 extending laterally above the circumference of the lower end 230 of the support 23. The support 23 is provided with a locking portion 232 located above the table 231. A plurality of locking ribs 233 extending axially are provided around the periphery of the locking portion 232. The radial width 233w of the lock ribs 233 gradually increases from the upper end to the lower end. However, the outer diameter of the arrangement of the lock ribs 233 is smaller than the outer diameter of the table 231. An axially extending engagement strip 234 is provided on the circumference of the lock portion 232, and the radial width 234w of the engagement strip 234 is larger than the radial width 233w of the lock ribs 233. The intermediate shaft 21 has a hollow, circular embedding space 210 (see also FIGS. 4 and 5) and an embedding opening 211 at its lower end. The inner diameter of the embedding space 210 is equal to the outer diameter of the arrangement of the lock ribs 233. The inner wall of the embedding space 210 is concave, corresponding to the position of the engagement strip 234 and having an axially extending engagement groove 212, the lower end of which is connected to the end of the embedding opening 211. When the support post 23 is coupled to the lower end of the intermediate shaft 21, the engagement strip 234 is aligned with the engagement groove 212 (see FIG. 5 ), and the locking portion 232 is pressed into the embedding opening 211, so that the engagement strip 234 is inserted into the engagement groove 212 and slides along the engagement groove 212. The locking rib 233 adheres closely to the inner wall of the embedding space 210 until the embedding opening 211 contacts the table 231, and the support post 23 is fixed to the lower end of the intermediate shaft 21, the engagement strip 234 is embedded in the engagement groove 212, and the support post 23 can rotate together with the intermediate shaft 21.

[0016] As shown in FIG. 2 , the meat grinder bowl 30 has a circular receiving recess 31 on its inner bottom surface. The inner diameter of the receiving recess 31 is the same as the outer diameter of the circumferential surface of the lower end 230 of the support 23. The lower end 230 can be recessed into the receiving recess 31, and the lower surface of the table 231 contacts the edge of the receiving recess 31. The lower end 230 of the support 23 is recessed into the receiving recess 31 and serves as a rotation fulcrum for the support 23 connected to the lower end of the intermediate shaft 21, allowing the meat grinder blade assembly 20 to rotate smoothly on this support point when driven by the drive mechanism 10.

[0017] By setting the locking unit A, the intermediate shaft 21 and the support 23 made of different materials can be combined and rotated together. The meat grinder blade assembly 20 is formed by combining the intermediate shaft 21 and the support 23, and a circular receiving recess 31 is provided on the inner bottom surface of the meat grinder bowl 30, into which the lower end 230 of the support 23 is embedded to form a rotation support point. Since the meat grinder bowl 30 does not need to be provided with a support shaft or magnetic connecting member, the meat grinder bowls are easy to clean and stack, and can be heated directly in a microwave oven, making them more convenient to use.
