Description

Technical Field

[0001] This utility model relates to the field of food heating machine technology, and in particular to a pancake baking machine with uniform heating. Background Technology

[0002] A toaster can heat up waffles, pancakes, bread, or sandwiches. The operation of a toaster is simple, quick, and easy, making it especially popular with busy working professionals or those in a rush.

[0003] The heating element in most pancake makers on the market is a tubular heating element, which is welded to or directly clipped to the bottom of the baking tray or installed below the tray. A heat reflector and insulation cotton are installed below the heating element to reduce the temperature of the outer casing and prevent burns.

[0004] Because the heating element is tubular, only a very limited surface area contacts the bottom of the baking pan, or there is no contact at all. During heating, the baking pan experiences uneven heating; areas near the heating element are heated to the set temperature, while areas further away heat up more slowly and may not reach the set temperature. Furthermore, the very limited contact area between the heating element and the baking pan results in low heat transfer efficiency and low heat utilization.

[0005] Currently, the baking trays of food heating machines on the market have relatively simple shapes and cannot be replaced with different shapes, making it inconvenient for users to heat foods of different shapes. Utility Model Content

[0025] The following is combined Figures 1 to 5 This invention describes a pancake baking machine with uniform heating according to an embodiment of the present invention.

[0026] A pancake maker with uniform heating includes a symmetrically foldable outer shell 1, a baking tray 2, a heating plate 3, and a heating element 4; the upper and lower ends of the outer shell 1 are provided with recesses, and the heating plate 3 is installed in the recesses; the heating element 4 is fixedly attached to the back of the heating plate 3; the baking tray 2 is detachably installed inside the front of the heating plate 3, and the front of the baking tray 2 is flush with the front of the outer shell.

[0027] A uniformly heated baking pancake maker is used to heat food. A heating element 4 is fixedly attached to the back of a heating plate 3, and a baking pan 2 is detachably installed inside the front of the heating plate 3. The heating element 4 can evenly heat the back of the heating plate 3, transferring heat to the baking pan 2 through the heating plate 3. The baking pan 2 then heats the food, resulting in uniform heating. Because the baking pan 2 is installed inside the front of the heating plate 3, all four sides of the baking pan 2 are heated, effectively achieving high heat transfer efficiency.

[0028] The baking tray 2 is detachably mounted to the heating plate 3, facilitating the installation of different shaped baking trays 2 on the heating plate 3 to meet individual user needs. The baking tray 2 is a replaceable component and can be a waffle tray, sandwich tray, or pancake tray of different shapes, etc. These trays have the same outer dimensions, allowing them to fit perfectly inside the heating element 4. When different food trays are used, the temperature and heating time of the toaster can be adjusted accordingly.

[0029] Specifically, the heating element 4 includes a heating film 41 and an insulating layer 42. The heating film 41 has an insulating layer 42 at both its front and rear ends. The insulating layer 42 ensures the power supply to the heating film 41 and guarantees safety. The insulating layer 42 is printed on the back of the heating plate 3 first, then the heating film 41 is printed, and finally the insulating layer 42 is printed again. A heat insulation element is provided on the side of the insulating layer 42 away from the heating plate 3. This heat insulation element separates the heat generated by the heating element 4 from the outer casing 1, reducing the surface temperature of the outer casing 1.

[0030] Specifically, the heating plate 3 has a relief cavity on its front side, and the baking plate 2 is installed inside the relief cavity. This makes the baking plate 2 fit the heating plate 3 more closely, and the bottom of the baking plate 2 is in complete contact with the surface of the heating plate 3, so that the heat emitted by the heating plate 3 can be better transferred to the baking plate 2.

[0031] Specifically, the heating element 4 has a hollow double-layer design, which can be in a vacuum state; the hollow design in the middle effectively reduces the transfer of heat from the heating element 3 to the outside of the outer shell 1, thereby reducing the surface temperature of the outer shell 1; the hollow space can be in a vacuum state.

[0032] Specifically, the heat insulation component between the heating element 4 and the inner side of the outer shell 1 includes a metal reflector 10 and a heat insulation layer 11. The metal reflector 10 is installed on the inner side of the outer shell 1. The metal reflector 10 reflects the heat generated by the heating element 4, reducing the heat transfer to the outer shell. The heat insulation layer 12 is made of MICA or non-metallic material. The heat insulation layer 11 reduces the heat transfer to the outer shell 1, thereby effectively reducing the surface temperature of the outer shell 1 and preventing burns to the user.

[0033] Specifically, a fixing block 5 and a telescopic component 6 are respectively installed on the upper and lower sides of the baking tray 2; slots 7 are respectively provided on the upper and lower sides of the clearance cavity, and the fixing block 5 and the telescopic component 6 can be detachably inserted into the slots 7. This facilitates the removal of the baking tray 2. When installing the baking tray 2, first insert the end of the fixing block 5 into one slot 7, and then insert the telescopic component 6 into the other slot 7. The telescopic component 6 can extend or retract, which helps the telescopic component 6 to be inserted into or removed from the slot 7.

[0034] Further explanation: A mounting hole 21 is provided on one side of the baking pan 2 where the telescopic component 6 is installed; the telescopic component 6 includes a movable block 61 and a spring 62; the movable block 61 is slidably disposed within the mounting hole 21, one end of the movable block 61 protrudes outside the mounting hole 21, and the other end of the movable block 61 is limited to slide within the mounting hole 21; the spring 62 is located between the bottom of the mounting hole 21 and the movable block 61, and is used to support the movable block 61 protruding outside the mounting hole 21; a square hole 22 is provided on the front of the baking pan 2 at the mounting hole 21, and the square hole 22 communicates with the mounting hole 21; a puller 63 protrudes from one side of the movable block 61, and the puller 63 is located within the square hole 22. The movable block 61 can be moved up and down by pulling the puller 63, thus inserting or removing it from the slot 7. The spring 62 is located between the bottom of the mounting hole 21 and the movable block 61, and the spring 62 can lift the movable block 61. When the movable block 61 moves to the position of the slot 7, the spring 62 can lift the movable block 61 and insert it into the slot 7.

[0035] Specifically, a connector 8 is provided on the outer side of the housing 1, and the connecting end of the connector 8 is connected to the heating film 41 for easy power connection. The connecting end of the connector 8 is provided with silver contacts, and the heating film 41 and the connector 8 are electrically connected through the silver contacts.

[0036] To further explain, baking pan 2 and heating pan 3 are made of metal. This helps with heat dissipation.

[0037] Specifically, the outer shell 1 includes an upper shell 101 and a lower shell 102. One side of the upper shell 101 is rotatably connected to one side of the lower shell 102, and a handle 9 is provided on the other side of the upper shell 101 and the other side of the lower shell 102, respectively. This facilitates opening or closing the upper shell 101 and the lower shell 102.

[0038] Specifically, the insulating layer 42 is made of materials such as mica film, quartz film, boron nitride thin film, boron nitride coating, Teflon layer, thermally conductive silicone, or thermally conductive grease; an NTC thermistor is installed on the heating film 41 to measure and control the temperature, helping users to know the temperature.

[0039] This invention provides three different heat insulation designs to reduce the temperature of the product casing. The first design involves directly applying or printing an insulating composite material onto the side of the insulating layer 42 of the heating element 4 near the casing 1, and then fixing it to the back of the heating element through sintering or other curing methods. The second design uses a vacuum double-layer design for the heating element 4, with the heating film 41 and the insulating layer 42 printed on the heating element layer 31. The space between layers 31 and 32 is hollow, effectively blocking heat transfer towards the casing; this design provides good heat insulation. The third design involves adding a heat reflector 10, MICA, or other heat insulation materials to the casing 1 component to reduce heat transfer to the casing.
