Description

Technical Field

[0001] This utility model relates to the field of pancake maker technology, and in particular to a new type of energy-saving pancake maker. Background Technology

[0002] A pancake machine is an important piece of equipment for making pancakes, especially an integrated double-sided heating pancake machine, which is suitable for producing various types of pancakes.

[0003] The heating element of existing pancake machines is a coiled heating resistance wire set in the upper and lower pans. The heating wire is an integrated structure. If the resistance wire fails or is damaged, not only is it difficult and time-consuming to disassemble the equipment, but the cost of replacing the entire resistance wire is also high. In addition, pancake machines can be driven by 220V single-phase electricity or 380V three-phase electricity. When the resistance wire in the traditional upper and lower pans is connected to 380V three-phase electricity, it reuses one of the three-phase live wires, resulting in high energy consumption, a large impact on the power grid, and easy damage to the electricity meter. This is not conducive to energy saving and safe use.

[0004] To address the above problems, a new type of energy-saving pancake maker has been proposed. Utility Model Content

[0005] The main purpose of this utility model is to provide a new type of energy-saving pancake maker, which solves the problems mentioned in the background art.

[0006] The objective of this utility model can be achieved by adopting the following technical solution: A novel energy-saving pancake maker includes a pancake maker body, which includes an upper pancake plate assembly and a lower pancake plate assembly; The upper and lower baking pan assemblies are each provided with a baking pan on their opposite sides. A heat-concentrating tube groove is welded and fixed to the bottom of the baking pan, and a heating tube is detachably installed in the heat-concentrating tube groove.

[0007] Furthermore, the side of the heat-gathering tube groove that contacts the pancake plate has an open structure, and the four sides of the open structure are welded and fixed to the bottom surface of the pancake plate. Several heat-gathering tube grooves are provided, and at least one set of heating tubes is provided in the heat-gathering tube grooves.

[0008] Furthermore, the two ends of the heating tube extend out of the heat-collecting tube groove, and the two ends are clamped and fixed by a reinforcing handle that is installed with the screw of the heat-collecting tube groove. External wiring is electrically led out from the two ends.

[0009] Furthermore, six sets of fastening screws are welded to the bottom of the pancake plate, and a heat insulation plate located at the bottom of the heat-gathering tube groove is movably mounted on the fastening screws.

[0010] Furthermore, the diameter of the pancake board is larger than the diameter of the heat insulation board, and the outer periphery of the heat insulation board is movably fitted with a detachable side cover, the side cover including a first separation cover and a second separation cover.

[0011] Furthermore, the first separation cover and the second separation cover are assembled together by a snap-fit ​​structure, and the second separation cover is also provided with a U-shaped groove for the external wiring to pass through.

[0012] Furthermore, the bottom of the side cover abuts against the base for supporting the pancake maker body, and the top plate of the base is threaded with an adjusting sleeve for passing through the fastening screw, and the bottom of the fastening screw extends out of the lowest end of the adjusting sleeve, and the top of the adjusting sleeve movably abuts against the bottom of the heat insulation plate.

[0013] Furthermore, neutral wire terminal blocks and live wire terminal blocks for connecting external wiring are detachably installed on both sides of the outer wall of the base.

[0014] Furthermore, a top frame is fixed to the top periphery of the base, and a hydraulic cylinder is bolted to the top of the top frame. The output end of the hydraulic cylinder is fixedly connected to the top cover of the upper soldering plate assembly, and a controller is provided on the support legs of the base.

[0015] The beneficial technical effects of this utility model are as follows: This utility model, through the design of a distributed heating structure, evenly covers the bottom of the griddle with heat-concentrating tubes containing heating tubes. This not only provides efficient heating, but also allows for quick replacement of damaged heating tubes through the convenient disassembly design of the first and second separation covers in the side cover. This saves maintenance time and avoids the need to replace the entire heating assembly, thus reducing maintenance costs. Secondly, the independent structure of the heating element allows for flexible use of both single-phase and three-phase power. In the case of three-phase power, the heating elements can be connected to the live wire terminal block in pairs to ensure the balance of three-phase power usage, thereby achieving energy saving and ensuring the safety of the power grid supply.

[0018] To enable those skilled in the art to understand the technical solution of this utility model more clearly, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings, but the implementation of this utility model is not limited thereto.

[0019] like Figures 1-5 As shown, this embodiment provides a novel energy-saving pancake maker, including a pancake maker body 4. The pancake maker body 4 includes an upper pancake plate assembly 401 and a lower pancake plate assembly 402. A pancake plate 403 is provided on the opposite side of the upper pancake plate assembly 401 and the lower pancake plate assembly 402. A heat-collecting tube groove 405 is welded and fixed to the bottom of the pancake plate 403. A heating tube 406 is detachably installed in the heat-collecting tube groove 405.

[0020] In the above structure, after the heating tube 406 is powered on, it radiates heat to the outside through the filamentary radiator made of high-temperature rare metal inside.

[0021] The side of the heat-collecting tube groove 405 that contacts the pancake plate 403 is an open structure. The four walls of the open structure are welded and fixed to the bottom surface of the pancake plate 403. Several heat-collecting tube grooves 405 are provided, and at least one set of heating tubes 406 is provided in the heat-collecting tube groove 405. The heat-collecting tube grooves 405 are evenly distributed on the bottom of the pancake plate 403. The heat transfer efficiency is improved through the heat conduction and reflection of the concave structure of the heat-collecting tube groove 405. The gaps between the heat-collecting tube grooves 405 are filled with heat-insulating material. In actual implementation, different numbers of heat-collecting tube grooves 405 and heating tubes 406 are set according to the size and power of the upper and lower pancake plates.

[0022] The two ends of the heating tube 406 extend into heat-collecting tube grooves 405. The two ends are clamped and fixed by reinforcing handles 407 that are screwed into the heat-collecting tube grooves 405. External wiring 408 is electrically led out from the two ends. The reinforcing handles 407 can not only fix the heating tube 406, but also facilitate disassembly and installation.

[0023] The bottom of the pancake plate 403 is also welded with six sets of fastening screws 409. A heat insulation plate 411 located at the bottom of the heat-gathering tube groove 405 is movably installed on the fastening screws 409. The heat insulation plate 411 is used to prevent heat loss downward and to protect the internal heat-gathering tube groove 405. The heat insulation plate 411 and the top of the base 1 are also filled with heat insulation material.

[0024] The diameter of the pancake plate 403 is larger than the diameter of the heat insulation plate 411. The heat insulation plate 411 is movably fitted with a separable side cover 404. The side cover 404 includes a first separation cover 404a and a second separation cover 404b. The side cover 404 has good elastic deformation and a thickness of 0.5cm.

[0025] The first separation cover 404a and the second separation cover 404b are assembled and installed together by a snap-fit ​​structure. The second separation cover 404b is also provided with a U-shaped groove for the external wiring 408 to pass through. When disassembling, the second separation cover 404b is deformed into a gathered shape and slides out from the first separation cover 404a.

[0026] The bottom of the side cover 404 abuts against the base 1, which supports the pancake maker body 4. The top plate of the base 1 is threaded with an adjusting sleeve 410 for passing through the fastening screw 409. The bottom of the fastening screw 409 extends beyond the lowest end of the adjusting sleeve 410. The top of the adjusting sleeve 410 moves to abut against the bottom of the heat insulation plate 411. The bottom of the fastening screw 409 is a nut, and the bottom of the adjusting sleeve 410 is also a nut. This allows the height of the fastening screw 409 against the heat insulation plate 411 to be adjusted by turning the wrench knob, thereby achieving the purpose of balancing the lower pancake assembly 402. After the fastening screw 409 is tightened, the nut knob at the bottom of the fastening screw 409 clamps the nut at the bottom of the adjusting sleeve 410, thereby locking the lower pancake assembly 402.

[0027] The outer walls of the base 1 are detachably equipped with neutral wire terminal block 6 and live wire terminal block 7 for connecting external wiring 408. Neutral wire terminal block 6 and live wire terminal block 7 are connected to the circuit in the same way when connected to single-phase 220V and three-phase 380V power supply. Neutral wire terminal block 6 is connected to one of the external wiring 408 of each heating tube 406 independently. Live wire terminal block 7 needs to be replaced with different terminal blocks according to 220V / 380V to distinguish different wiring methods.

[0028] A top frame 2 is fixedly installed on the top periphery of the base 1. A hydraulic cylinder 5 is bolted to the top of the top frame 2. The output end of the hydraulic cylinder 5 is fixedly connected to the top cover of the upper soldering plate assembly 401. A controller 3 is installed on the support leg of the base 1.

[0029] The working principle of this device is as follows: When using this device, you can choose to use 220V single-phase power or 380V three-phase power.

[0030] When connected to 220V single-phase power, the two external wires 408 of the heating element 406 are independently connected to the terminals on the neutral wire terminal block 6 and the live wire terminal block 7. When connected to 380V three-phase power, one of the external wires 408 of the heating element 406 is independently connected to the terminal on the neutral wire terminal block 6, and the other external wire 408 is connected in pairs on the live wire terminal block 7. This achieves the balance of three-phase four-wire power supply in three-phase power supply, achieves the purpose of energy saving, and avoids the drawbacks of traditional single resistance wire heating, which reuses the 380V live wire, resulting in excessive power consumption and safety hazards to the power grid.

[0031] When the heating tube 406 malfunctions, the second separation cover 404b can be detached from the first separation cover 404a by micro-squeezing deformation, and then slid upwards to expose the heat-gathering tube groove 405 and the external wiring 408 to the outside. Open the protective covers of the live wire terminal block 7 and the neutral wire terminal block 6, disassemble the external wiring 408 of the damaged heating tube 406, remove the reinforcing handle 407, pull the heating tube 406 out of the heat-gathering tube groove 405, replace it with a new heating tube 406 and slide it into the hole of the heat-gathering tube groove 405, reinstall the reinforcing handle 407, and reconnect the two external wirings 408 to complete the replacement.

[0032] By sampling the above structure, the problem of traditional integrated coiled resistance wire being difficult to disassemble and replace after damage, and requiring high overall scrap costs for replacement, is solved.

[0033] The above are merely further embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope disclosed by this utility model, based on the technical solution and concept of this utility model, shall fall within the protection scope of this utility model.

[0034] All standard parts used in this application can be purchased from the market, and can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art. The control method is automatic control through a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art and is common knowledge in the field. Since this application is mainly used to protect mechanical devices, the control method and circuit connection will not be explained in detail in this application.
