Description

Technical Field

[0001] This utility model relates to the field of cooking equipment technology, specifically to a pot positioning device for a stir-fry machine. Background Technology

[0002] A stir-fry machine is an automated cooking device that offers advantages such as reducing manual labor intensity, increasing work efficiency, and lowering the skill requirements for chefs. Existing stir-fry machines 100' generally include a worktable 110' with a glass heating panel 112'. A robotic arm 120' is located on one side of the heating panel 112' on the worktable 110' for opening and closing the lid. The pot 140' is placed directly on the glass heating panel 112' for heating. When it's time to cover the pot with the lid 130', the robotic arm 120' flips the lid to place it on the pot 140' on the heating panel 112'. Figure 1 and Figure 2 As shown, the heating panel of the company's existing cooking machine is a circular heating panel 112', and the top panel of the worktable 110' is a sheet metal panel 111' with a circular cutout in the middle to facilitate the installation of the glass heating panel 112'. At the same time, in order to position the pot 140' so that it does not slide freely during use, a protruding positioning post 10' is set on the sheet metal panel 111' on both sides of the heating panel 112' on the worktable 110'. The positioning post 10' is locked to the sheet metal panel 111' of the worktable 110' by screws (not shown) to position the pot 140' on the central circular heating panel 112'. However, the applicant found that the heating panel on the worktable of the existing cooking machine was not aesthetically pleasing. To make the heating panel more attractive, the applicant has developed a cooking machine with a square heating panel. The square heating panel is larger than the original circular heating panel, meaning it not only occupies the space of the original heating panel but also part of the sheet metal space on the top surface of the worktable. This presents new problems for the placement of the pot positioning structure. The original positioning structure, which uses screws for locking, is now occupied by the glass heating panel, and the screws cannot be locked to the glass. Therefore, it is necessary to develop a new pot positioning device for the cooking machine to solve the above problems, hence this utility model. Utility Model Content

Detailed Implementation

[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0028] This utility model provides a pot positioning device for a stir-fry machine, see [link to relevant documentation]. Figures 3 to 6 The cooking machine 100 includes a worktable 110 with a heating device at the bottom. The top surface of the worktable 110 includes a square glass heating panel 112 and a sheet metal panel 111. The sheet metal panel 111 is hollow in the middle, and its shape and size match the square heating panel 112. The square heating panel 112 is located in the hollow part of the sheet metal panel 111. The heating device, such as a heating coil, is located at the bottom of the square heating panel 112 and is used to heat the pot 140 placed on the square heating panel 112. Specifically, on one side of the sheet metal panel 111 located on the square heating panel 112... Figure 5 A robotic arm 120 is provided in the middle of the right side shown. A pot lid 130 is installed on the robotic arm 120. A spatula and other components can also be installed on the inner side of the pot lid 130. The robotic arm 120 can rotate around the horizontal axis to drive the pot lid 130 to flip towards or away from the pot 140 on the square heating panel 112, so that the pot lid 130 can cover the pot 140 or separate from the pot 140.

[0029] The positioning device for the cookware 140 is located on the sheet metal panel 111 on the side of the square heating panel 112. Specifically, the positioning device for the cookware 140 in this embodiment of the present invention includes two structural forms, which will be described below as structural form one and structural form two, respectively.

[0030] More specifically, structural form one is as follows: See Figures 3 to 5 The positioning device is located on the sheet metal panel 111 on one side of the square heating panel 112 and partially protrudes towards the side where the square heating panel 112 is located. For ease of description and distinction, this positioning device is referred to as a positioning bracket 10 to differentiate it from another type of positioning device. This positioning bracket 10 is not located on the same side as the robotic arm 120. Preferably, see [reference needed]. Figure 5 The robotic arm 120 is mounted on the sheet metal panel 111 on the right side of the square heating panel 112. The positioning bracket 10 is mounted on the sheet metal panel 111 on the front side of the square heating panel 112 (optionally, it can also be mounted on the rear side, as long as the positioning bracket 10 and the robotic arm 120 are respectively located on adjacent sides of the square heating panel 112, i.e., intersecting, two-point positioning can be achieved). In this way, the positioning bracket 10 and the robotic arm 120 can jointly form a two-point positioning for the pot 140. In use, simply place the side of the pot 140 against the side of the positioning bracket 10, and then place the side of the pot 140 facing the robotic arm 120 against the inner side of the robotic arm 120 to achieve positioning. More specifically, the positioning bracket 10 includes a first bracket body 11, a second bracket body 12, a third bracket body 13, and a fourth bracket body 14 connected in sequence. The first support body 11 and the fourth support body 14 are arranged in parallel and connected to the sheet metal panel 111 respectively. In the installed state, the first support body 11 and the fourth support body 14 are perpendicular to the sheet metal panel 111. The second support body 12, the first support body 11 and the third support body 13 are arranged perpendicular to each other, that is, they are perpendicular to each other in pairs. In the installed state, the second support body 12 extends from the outside of the square heating panel 112 toward the center of the square heating panel 112. The third support body 13, the second support body 12 and the fourth support body 14 are arranged perpendicular to each other. In the installed state, the second support body 12 and the third support body 13 are both suspended parallel above the square heating panel 112. In this embodiment of the present invention, both the first support body 11 and the fourth support body 14 are fixed to the sheet metal panel 111 by positioning components, such as conventional fastening screws. Specifically, each of the first support body 11 and the fourth support body 14 has a connecting hole 15 extending along its respective axial direction on its end face. The connecting hole 15 is a threaded hole, and screws are inserted into the connecting hole 15 to fix it to the sheet metal panel 111. This design facilitates assembly and disassembly, resulting in a simple structure and low cost. (See also: [link to embodiment of the present invention]) Figure 4 and Figure 5The end of the third support body 13 connected to the second support body 12 forms a contact and positioning against the pot 140. Therefore, the length of the third support body 13 is set to be longer than the length of the other support bodies, that is, the length of the second support body 12 is less than the length of the third support body 13. In order to ensure that the second support body 12 and the third support body 13 are on a horizontal plane rather than in an inclined state, it is preferable that the length of the first support body 11 and the length of the fourth support body 14 are the same.

[0031] According to some preferred embodiments of the present invention, such as Figure 3 As shown, there are rounded transitions between the first support body 11 and the second support body 12, between the second support body 12 and the third support body 13, and between the third support body 13 and the fourth support body 14. This improves the appearance while reducing stress concentration and increasing processing accuracy and efficiency.

[0032] According to some preferred embodiments of the present invention, the positioning bracket 10 adopts an integral molding structure. For example, the positioning bracket 10 is made of steel bars and is formed by bending process to form a first bracket body 11, a second bracket body 12, a third bracket body 13 and a fourth bracket body 14 connected in sequence.

[0033] For the positioning device of structural form two, such as Figure 6 As shown, to easily distinguish it from the positioning device of structural form one, the positioning device of structural form two is described as a positioning frame 20. Specifically, the positioning device of structural form two includes two positioning frames 20, which are arranged opposite to each other and spaced apart on the sheet metal panel 111 on the side where the robotic arm 120 is located, and are respectively located on both sides of the robotic arm 120. Each positioning frame 20 extends towards the side where the square heating panel 112 is located in the direction away from the robotic arm 120, that is, the robotic arm 120 is positioned as shown in the figure. Figure 6 On the sheet metal panel 111 on the right side of the square heating panel 112 shown, two positioning brackets 20 extend from right to left. This positioning device, with its two positioning brackets 20 and robotic arm 120, forms a three-point positioning system for the cookware 140. In this embodiment of the invention, the positioning brackets 20 are inverted L-shaped and plate-like. More specifically, as... Figure 6 As shown, any positioning frame 20 includes a first frame 21 and a second frame 22 connected together. The first frame 21 is perpendicular to the sheet metal panel 111 in the installed state, and the second frame 22 is parallel to the sheet metal panel 111 or the square heating panel 112 in the installed state. The bottom end of the first frame 21 is welded to the sheet metal panel 111, and the second frames 22 of the two positioning frames 20 form abutment positioning for the cookware 140. Specifically, the bottom ends of the first frames 21 of the two positioning frames 20 are welded to the sheet metal panel 111 at two corner positions of the square heating panel 112. The second frames 22 of the two positioning frames 20 are parallel and respectively composed of... Figure 6The right end extends horizontally to the left end as shown. Preferably, there is a rounded transition between the first frame 21 and the second frame 22. This improves the appearance while reducing stress concentration and improving processing accuracy and efficiency. The projection of the second frame 22 of any positioning frame 20 onto the horizontal plane falls entirely on the sheet metal panel 111 or partially on the square heating panel 112. This design allows the positioning frame 20 to occupy a smaller area of ​​the square heating panel 112 and avoids interference between the positioning frame 20 and the cookware 140, which would make positioning difficult or impossible.

[0034] It should be noted that, regardless of whether it is the positioning device of structure form one or structure form two, during use, since the lid 130 has a flange (not shown, which is the existing conventional structure) that matches the opening of the pot 140, the flange can achieve secondary positioning when the lid 130 is closed on the pot 140.

[0035] The pot positioning device of the cooking machine of this utility model is designed to address the issue that existing positioning devices cannot be installed or used when the heating panel of the cooking machine 100 is changed from round to square. By improving the structure and setting position of the positioning device, the positioning device can achieve two-point and three-point positioning respectively, which is fast and low cost.

[0036] It should be understood that the specific embodiments described above are merely illustrative or explanatory of the principles of this utility model and do not constitute a limitation thereof. Therefore, any modifications, equivalent substitutions, improvements, etc., made without departing from the spirit and scope of this utility model should be included within its protection scope. Furthermore, the appended claims are intended to cover all variations and modifications falling within the scope and boundaries of the appended claims, or equivalent forms of such scope and boundaries.
