Description

Technical Field

[0001] This utility model belongs to the technical field of kitchen utensils and relates to a food warming board. Background Technology

[0002] Because the process of cooking and serving dishes before a meal now takes a long time, the first dishes tend to cool down easily, or other reasons can cause the food to cool down during long waits. Therefore, food warmers are often used. A food warmer is a household appliance mainly used to maintain the temperature of food, keeping it within a suitable eating range.

[0003] A food warmer disclosed in Chinese patent CN221844504U includes an outer shell, which is an integral structure. The outer shell includes several bending portions and several wrapping portions. Two adjacent wrapping portions are connected by the bending portions. The bending portions are made of soft rubber, and the wrapping portions are made of soft rubber or hard rubber.

[0004] When using this food warmer, the food is placed on top of the outer shell. However, the outer shell is a single piece, meaning the bottom of it contacts the tabletop. As the heating plate transfers heat to the food, it also transfers heat to the tabletop, potentially damaging it. Furthermore, the entire warmer rotates via a bend made of soft rubber. Even after the outer shell is opened, the bend continues to rotate, causing the outer shell to wobble when moving food, resulting in poor stability.

[0005] To address the aforementioned problems, this utility model proposes a food warming board. Utility Model Content

[0006] To address the problems existing in the background technology, this utility model proposes a food warming board.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows: It includes two bases arranged on the left and right sides. Two sets of hinges are symmetrically fixedly connected to the right side of the base on the left side. Each set of hinges includes two hinge rods. Two connecting rods are symmetrically fixedly connected to the left side of the base on the right side. The connecting rods correspond one-to-one with the hinges. One end of the connecting rod is located between the two corresponding hinge rods.

[0008] Both connecting rods are fixedly connected to a fixed shaft, and the hinge rod is rotatably sleeved on the end of the corresponding fixed shaft. Two protrusions are symmetrically slidably arranged at both ends of the two fixed shafts, and the protrusions are movably arranged in the corresponding hinge rod.

[0009] Each base has two fixed support legs at its bottom, and both bases have heat dissipation holes on their bottom surfaces. Both bases also have heating devices on their top surfaces.

[0010] Furthermore, two receiving grooves are symmetrically opened at both ends of the two fixed shafts, and the protrusions are slidably arranged in the corresponding receiving grooves. A spring is fixedly connected inside each receiving groove, and the other end of the spring is fixedly connected to one side of the corresponding protrusion. The end of the protrusion away from the spring is arc-shaped.

[0011] Two grooves are formed on the inner wall of each hinge rod, and the arc-shaped segment of the protrusion is movably set in the corresponding groove.

[0012] Furthermore, the two supporting corners of the base on the left side are fixedly connected to the two corners on the left side of the base, and the two supporting corners of the base on the right side are fixedly connected to the two corners on the right side of the base.

[0013] Furthermore, each of the two bases has a slot at each corner. The slot on the left base corresponds to the corner of the right base, and the corner of the left base corresponds to the slot on the right base. When the two bases are closed, the corners are movably positioned in the corresponding slots.

[0014] Furthermore, the heating device includes a heating wire and a heating plate, with the heating plate fixedly connected to the top of the base and the heating wire fixedly connected to the bottom surface of the heating plate;

[0015] Both bases have power interfaces fixedly connected to their inner sides, and the power interfaces are connected to the electrical terminals of the heating wires via wires.

[0016] Furthermore, the heat dissipation hole is connected to the inner cavity of the corresponding base, and the heating wire is located at the top of the inner cavity of the corresponding base.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. The food warmer has support corners fixedly connected to the bottom of both bases. When the two bases are opened, the support corners will support the bottom of the bases, creating a gap between the bottom of the base and the table. When the heating wire is heating, the heat dissipation holes will dissipate heat through the bottom of the base. The heat is discharged through the gap at the bottom of the base, reducing the possibility of the base overheating and damaging the table.

[0019] 2. The food warming board has two protrusions at both ends of each fixed shaft. When the base is rotated, the hinge rod will rotate on the corresponding fixed shaft. The inner wall of the hinge rod will push the protrusion, causing the protrusion to slide into the receiving groove and compress the spring. When the two bases are rotated to the level or closed state, the grooves correspond one-to-one with the receiving grooves, causing the spring to push the protrusion into the corresponding groove, thereby limiting the position of the two bases and making the connection between the two bases more stable.

[0020] 3. The food warmer has corner supports and slots on the base. When the two bases are closed, the corner supports will lock into the corresponding slots. With the help of the protrusions, the two bases are connected more tightly, making it easier to move and store. Attached Figure Description

[0030] 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.

[0031] like Figures 1-8 As shown, the technical solution adopted by this utility model is as follows: A food warming board includes two bases 7 arranged on the left and right sides. Two sets of hinges are symmetrically fixedly connected to the right side of the base 7 on the left side. Each set of hinges includes two hinge rods 12, one end of which is fixedly connected to the right side of the base 7.

[0032] Two connecting rods 9 are symmetrically fixedly connected to the left side of the base 7 on the right side. One end of each connecting rod 9 is fixedly connected to the left side of the base 7. Each connecting rod 9 corresponds to a hinge, and one end of each connecting rod 9 is located between the two corresponding hinge rods 12. The connecting rods 9 and the corresponding hinge rods 12 are in sliding engagement.

[0033] Both connecting rods 9 are fixedly connected to a fixed shaft 4, and the hinge rod 12 is rotatably sleeved on the end of the corresponding fixed shaft 4. This allows the connecting rod 9 to rotate between the two corresponding hinge rods 12. Two protrusions 10 are symmetrically slidably arranged at both ends of the two fixed shafts 4, and the protrusions 10 are movably disposed within the corresponding hinge rod 12.

[0034] Two receiving grooves are symmetrically opened at both ends of the two fixed shafts 4, and the protrusions 10 are slidably disposed in the corresponding receiving grooves. A spring 11 is fixedly connected inside each receiving groove, and the other end of the spring 11 is fixedly connected to one side of the corresponding protrusion 10. The end of the protrusion 10 away from the spring 11 is arc-shaped. When the spring 11 is in its natural state, the arc-shaped end of the protrusion 10 extends out of the receiving groove.

[0035] Two grooves 13 are formed on the inner wall of each hinge rod 12, and the arc-shaped segment of the protrusion 10 is movably disposed in the corresponding groove 13. By positioning the protrusion 10 in the corresponding groove 13, the hinge rod 12 is positioned on the corresponding fixed shaft 4, thereby positioning the two bases 7.

[0036] Each base 7 has two fixed support corners 5 at its bottom.

[0037] The two support corners 5 of the base 7 on the left are fixedly connected to the two corners on the left side of the base 7. The two support corners 5 of the base 7 on the right are fixedly connected to the two corners on the right side of the base 7, so as to support the two bases 7 through the support corners 5.

[0038] Each of the two bases 7 has a slot 6 at each support corner 5 on its bottom surface. The slot 6 of the left base 7 corresponds one-to-one with the support corner 5 of the right base 7, and vice versa. When the two bases 7 are closed, the support corner 5 is movably positioned within the corresponding slot 6. The slots 6 facilitate the positioning of the support corner 5, making the connection between the two bases 7 more secure.

[0039] Heating devices are installed on the top of both bases 7.

[0040] The heating device includes a heating wire 3 and a heating plate 1. The heating plate 1 is fixedly connected to the top of the base 7, and the heating wire 3 is fixedly connected to the bottom surface of the heating plate 1. The heating wire 3, also known as an electric heating wire or heating element, is an existing product.

[0041] Power interfaces 2 are fixedly connected to the inside of the sides of both bases 7. The power interfaces 2 are connected to the electrical terminals of the heating wires 3 via wires. The heating wires 3 on the two bases 7 are powered through the power interfaces 2.

[0042] Both bases 7 have heat dissipation holes 8 on their bottom surfaces, which are connected to the inner cavities of the corresponding bases 7. Heating wires 3 are located at the top of the inner cavities of the corresponding bases 7. The heat generated by the heating wires 3 is located within the inner cavities of the bases 7, and some of the heat is dissipated through the heat dissipation holes 8.

[0043] Working principle:

[0044] In use, move the warming plate. Place one of the bases 7 on the right side of the table and rotate the left base 7 upwards. The hinge rod 12 will rotate on one side of the connecting rod 9, and the hinge rod 12 will rotate on the corresponding fixed shaft 4.

[0045] When the hinge rod 12 rotates, it moves the groove 13 along with it. The inner wall of the hinge rod 12 presses against the protrusion 10, causing the protrusion 10 to move into the receiving groove and compress the spring 11. During the rotation of the hinge rod 12, the inner wall of the hinge rod 12 abuts against the arc-shaped surface of the protrusion 10.

[0046] Similarly, if one of the bases 7 on the left is placed on a table, and the base 7 on the right is rotated upwards, the connecting rod 9 will rotate between the corresponding two hinge rods 12, and the fixed shaft 4 will rotate inside the hinge rod 12. The inner wall of the hinge rod 12 will press against the protrusion 10, causing the protrusion 10 to move into the receiving groove and compress the spring 11.

[0047] After rotating the base 7 to 180 degrees, the receiving groove and the recess 13 correspond one-to-one. At this time, the spring 11 will push the protrusion 10 into the recess 13. Position the hinge rod 12 on the fixed shaft 4 to position the two bases 7.

[0048] At this point, the support 5 supports the bottom of the base 7, and the two bases 7 are supported by the hinge rod 12 and the connecting rod 9. There is a gap between the bottom surface of the base 7 and the tabletop.

[0049] Connect the data cable to the power interface 2 to power the heating wire 3. The heating wire 3 heats the heating plate 1. The heat dissipation holes 8 will dissipate some of the heat, cooling the base 7 and reducing the risk of overheating and damage to the desktop.

[0050] After use, rotate one of the bases 7 upwards. Similarly, the hinge rod 12 will press against the protrusion 10. After rotating the base 7 to 180 degrees, the receiving groove and the recess 13 will correspond one-to-one, at which point the spring 11 will push the protrusion 10 into the recess 13.

[0051] At the same time, the two bases 7 move closer to each other, so that the support 5 is inserted into the corresponding slot 6.

[0052] Although the present invention 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 the present invention should be included within the protection scope of the present invention.
