Description

Technical Field

[0001] This utility model belongs to the field of food baking technology, specifically relating to a sandwich maker with an unfoldable lid. Background Technology

[0002] With the advancement of technology and the continuous improvement of people's quality of life, the choices of food are also increasing. Sandwiches are a typical Western food, made by sandwiching a few slices of meat, cheese, and various seasonings between two slices of bread. They are easy to eat. In order to achieve better taste and texture, the bread is first toasted, which requires the use of a sandwich maker.

[0003] A sandwich maker is a kitchen appliance that quickly makes sandwiches by heating from both sides. Its core components include upper and lower heating plates and a non-stick coating. Heat is transferred through heating elements to bake the food.

[0004] Currently, sandwich maker baking trays require additional tools to be removed for replacement or cleaning, making the process complicated, time-consuming, and inconvenient.

[0005] A search revealed that Chinese utility model patent CN222237487U discloses "a sandwich maker with an easy-to-change baking tray", which includes: a lower housing, a baking tray inside the lower housing, and arc-shaped mounting blocks fixedly installed on both sides of the baking tray. The lower housing has two sets of rectangular grooves, one set of placement grooves, one set of slots and one set of circular grooves inside. The two sets of rectangular grooves are equipped with disassembly components, realizing a self-locking function. This structure is simple, convenient and easy to operate.

[0006] Although existing sandwich makers, including those mentioned above, can disassemble and assemble the baking tray without the aid of tools, in actual use, both sets of disassembly components need to be pulled outwards simultaneously to disassemble the baking tray. Therefore, even the simple task of disassembling and assembling the baking tray requires the cooperation of two workers, which is quite troublesome.

[0007] To address the aforementioned problems, this utility model proposes a sandwich maker with an unfoldable lid. Utility Model Content

[0035] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0036] Please see Figures 1-4The present invention provides the following technical solution: a sandwich maker with an unfoldable lid, comprising two double-opening lids 1 arranged in a split configuration and a baking tray 2 disposed within the double-opening lids 1, and further comprising: a mounting base 22, a first magnetic suction plate 7 and a second magnetic suction plate 8.

[0037] Furthermore, by Figure 1 and Figure 2 As shown in this embodiment, the mounting base 22 is fixed to the bottom surface of the baking tray 2. A mounting groove 11 is provided on the double-opening cover 1 for the mounting base 22 to fit into. The first magnetic plate 7 is fixed to the bottom surface of the mounting groove 11, and the second magnetic plate 8 is fixed to the bottom surface of the mounting base 22 and attracts the first magnetic plate 7. With the above solution, when the user needs to use the sandwich maker, the baking tray 2 is first aligned with the mounting groove 11 on the double-opening cover 1 through the mounting base 22 on the bottom surface. Since the mounting base 22 and the mounting groove 11 adopt a fitting and embedding design, accurate positioning can be achieved.

[0038] As the mounting base 22 is fully embedded in the mounting groove 11, the first magnetic plate 7 fixed to the bottom surface of the mounting groove 11 and the second magnetic plate 8 on the bottom surface of the mounting base 22 attract each other due to their opposite magnetic poles, generating a stable magnetic attraction force that firmly fixes the baking tray 2 inside the double-opening lid 1, ensuring that the baking tray 2 will not shift or shake during subsequent use.

[0039] When the double-opening lid 1 is unfolded in a split manner, the two double-opening lids 1 open to the sides respectively. At this time, the baking tray 2 is connected to the mounting groove 11 of the double-opening lid 1 through the mounting base 22. The attraction between the first magnetic plate 7 and the second magnetic plate 8 allows the baking tray 2 to unfold stably with the double-opening lid 1, forming a flat operating area.

[0040] During the heating process, the heating element (usually an electric heating tube, not shown in the figure) inside the double-opening lid 1 heats the baking tray 2 evenly. Since the baking tray 2 is securely installed by the magnetic structure, it can ensure the stability of heat conduction and avoid uneven heating of the sandwich due to shaking of the baking tray 2.

[0041] When the user finishes making sandwiches and needs to clean the baking tray 2, they only need to apply an external force greater than the magnetic attraction force to pull the mounting base 22 out of the mounting slot 11, so that the second magnetic plate 8 separates from the first magnetic plate 7, thus easily removing the baking tray 2 for cleaning. This magnetic installation structure not only ensures the stability of the baking tray 2 during use, but also makes it easy for users to disassemble and install, improving the convenience and practicality of the sandwich machine.

[0042] Preferably, by Figure 1 and Figure 2As shown in this embodiment, there are two magnetic suction plates 7 and 8 symmetrically distributed. With the above scheme, when in use, the two sets of magnetic suction plates 7 and 8 are symmetrically arranged along the geometric center of the baking tray 2 to form a stable two-point positioning mechanism. When the double-opening lid 1 is opened and closed, the magnetic attraction force on the baking tray 2 passes through the central axis, avoiding the skew torque that may be caused by unilateral magnetic attraction, and further improving the stability of the baking tray 2.

[0043] Preferably, by Figure 1 and Figure 2 As shown, in this embodiment, it further includes: two positioning protrusions 6, which are symmetrically fixed to the bottom surface of the mounting base 22. A positioning groove 12 for the positioning protrusions 6 to be embedded is provided on the double-opening cover 1. After adopting the above solution, when the baking tray 2 is installed, the two positioning protrusions 6 on the bottom surface first form a mechanical pre-positioning structure with the positioning groove 12 on the double-opening cover 1.

[0044] The bottom of the positioning protrusion 6 has a trapezoidal structure, which ensures guidance during insertion and avoids jamming caused by interference fit.

[0045] Preferably, by Figure 1 and Figure 2 As shown in this embodiment, the outer wall of the positioning protrusion 6 is attached to the inner wall of the positioning groove 12. With the above solution, when the positioning protrusion 6 is fully inserted into the positioning groove 12, the outer wall of the positioning protrusion 6 is attached to the inner wall of the positioning groove 12. This attachment effectively restricts the lateral displacement of the baking tray 2. Combined with the magnetic attraction of the first magnetic plate 7 and the second magnetic plate 8, the stability of the installation of the baking tray 2 is further guaranteed.

[0046] Furthermore, due to the fit between the positioning protrusion 6 and the positioning groove 12, and the magnetic attraction between the first magnetic plate 7 and the second magnetic plate 8, when it is necessary to remove the baking tray 2, it is necessary to lift the baking tray 2 vertically (perpendicular to the top mounting surface of the double-opening lid 1). Even if the double-opening lid 1 is in an inclined state, as long as no vertical external force is applied to the baking tray 2, the baking tray 2 will not accidentally detach from the double-opening lid 1.

[0047] Preferably, by Figure 1 and Figure 3 As shown, in this embodiment, it further includes: two positioning short posts 9, which are symmetrically fixed on the top surface of the double-opening cover 1. A positioning hole 23 is provided on the baking tray 2 for the positioning short posts 9 to be inserted. After adopting the above solution, when the user installs the baking tray 2, the positioning short posts 9 on the top surface of the double-opening cover 1 first form a guide positioning structure with the positioning hole 23 of the baking tray 2.

[0048] The top of the positioning short column 9 is designed in the shape of a frustum, which ensures that the position can be automatically corrected by the guide slope without the need for precise alignment when inserted.

[0049] The symmetrically distributed positioning short posts 9 and the positioning protrusions 6 below form a double positioning structure, providing the accuracy of the baking tray 2 installation position and the stability of the installation.

[0050] Preferably, by Figure 1 and Figure 3 As shown, in this embodiment, it further includes two auxiliary blocks 24, which are symmetrically fixed at both ends of the baking pan 2. With the above solution, the two auxiliary blocks 24 serve as force application points during use, making it convenient for the user to disassemble the baking pan 2.

[0051] When the user needs to disassemble the baking tray 2, he / she holds the two auxiliary blocks 24 at both ends with both hands and pulls the baking tray 2 up to complete the disassembly of the baking tray 2.

[0052] If the pulling force is insufficient to overcome the magnetic attraction of magnetic plate 7 and magnetic plate 8, when lifting, some fingers apply an upward pulling force to the baking tray 2, while the remaining fingers limit the double-opening lid 1 to prevent it from moving upward with the baking tray 2.

[0053] Preferably, by Figure 1 As shown, in this embodiment, it further includes: a plurality of semi-cylindrical reinforcing ribs 21, which are evenly distributed and integrally formed on the top surface of the baking pan 2. With the above solution, the design of the plurality of semi-cylindrical reinforcing ribs 21 can effectively improve the structural strength of the baking pan 2 during use.

[0054] On the other hand, the design of the reinforced rib 21 can effectively prevent the sandwich from sticking to the baking pan 2.

[0055] Preferably, by Figure 1 and Figure 4 As shown, this embodiment further includes: a handle 3 and a locking element 5. A handle 3 is fixed to the free end of each of the two double-opening covers 1, and a crossbar 4 is fixed to the handle 3. The locking element 5 includes a sleeve 51, an elastic hook 52 and a toggle block 53 that are fixed together. The crossbar 4 on one handle 3 passes through the sleeve 51, and the crossbar 4 on the other handle 3 is embedded in the elastic hook 52 to form a locking structure. With the above solution, when the user needs to close the double-opening covers 1, he first holds the handles 3 on both sides and closes the two double-opening covers 1 towards the center.

[0056] When the double-opening cover 1 is closed to the critical position, the locking element 5 is rotated by the actuating block 53. When the elastic hook 52 contacts the crossbar 4, the locking element 5 continues to rotate. Because the crossbar 4 is cylindrical, its arc surface is forced to cause the elastic hook 52 to undergo elastic deformation. When the crossbar 4 passes the elastic hook 52, the elastic hook 52 returns to its original position under its own elastic force. At this time, the crossbar 4 is tightly locked into the hook cavity, forming a mechanical lock.

[0057] When unlocking, the user only needs to push the lever block 53 outward with one thumb, causing the elastic hook 52 to deflect synchronously. When the crossbar 4 separates from the elastic hook 52, the double-opening cover 1 can be easily opened.

[0058] It should be noted that the double-opening cover 1 is a commercially available standard device with a built-in power switch. Those skilled in the art can make conventional selections according to their needs. Its working principle is common knowledge known to those skilled in the art and has been fully disclosed in the prior art, so it will not be elaborated further in this article.

[0059] The circuit connection involved in this utility model is a common method used by those skilled in the art, and technical inspiration can be obtained through a limited number of experiments. It belongs to the widely used prior art.

[0060] Components not described in detail in this article are existing technologies.

[0061] The working principle and usage process of this utility model: When using the sandwich maker of this utility model, when the user needs to use the sandwich maker, first align the baking tray 2 with the mounting base 22 on the bottom surface of the double-opening cover 1 through the mounting slot 11. Since the mounting base 22 and the mounting slot 11 adopt a fitting and embedded design, precise positioning can be achieved.

[0062] As the mounting base 22 is fully embedded in the mounting groove 11, the first magnetic plate 7 fixed to the bottom surface of the mounting groove 11 and the second magnetic plate 8 on the bottom surface of the mounting base 22 attract each other due to their opposite magnetic poles, generating a stable magnetic attraction force, which firmly fixes the baking tray 2 inside the double-opening lid 1, ensuring that the baking tray 2 will not shift or shake during subsequent use.

[0063] When the double-opening lid 1 is unfolded in a split manner, the two double-opening lids 1 open to the sides respectively. At this time, the baking tray 2 is connected to the mounting groove 11 of the double-opening lid 1 through the mounting base 22. The attraction of the first magnetic plate 7 and the second magnetic plate 8 enables the baking tray 2 to unfold stably with the double-opening lid 1, forming a flat operating area.

[0064] During the heating process, the heating element inside the double-opening lid 1 heats the baking tray 2 evenly. Since the baking tray 2 is securely installed by the magnetic structure, it can ensure the stability of heat conduction and avoid uneven heating of the sandwich due to shaking of the baking tray 2.

[0065] When the user finishes making sandwiches and needs to clean the baking tray 2, they only need to apply an external force greater than the magnetic attraction force to pull the mounting base 22 out of the mounting slot 11, so that the second magnetic plate 8 separates from the first magnetic plate 7, thus easily removing the baking tray 2 for cleaning. This magnetic installation structure not only ensures the stability of the baking tray 2 during use, but also makes it easy for users to disassemble and install, improving the convenience and practicality of the sandwich machine.

[0066] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
