Abstract
Description
Technical Field
[0001] This utility model relates to food cooking and processing appliances, and more particularly to a dual-heat-source food cooking mechanism. Background Technology
[0002] To improve dining convenience, the applicant has designed a food vending machine, with publication number CN112716256A and title "A Steamed Food Machine," for use in food preparation and vending. Existing food preparation vending machines cook food using steam or an electric stove. While steam cooking allows for slow cooking with stirring after boiling to improve texture, the long boiling time results in low processing efficiency. Electric stoves solve the slow boiling time problem but cannot achieve the stirring-based slow cooking to improve texture. For foods requiring water to be added just before cooking, a separate water-adding piercing structure is needed to puncture the lid and add water. Then, during the heating and cooking process, a steam input pipe is inserted through the punctured lid hole. This method not only prolongs food preparation time but also causes significant air leakage due to the mismatch between the steam input pipe and the lid hole. In this case, an additional lid needs to be placed over the hole, and steam extraction is required to remove the overflowing steam, complicating the equipment structure. Utility Model Content
[0003] The first objective of this invention is to provide a dual-heat-source food cooking mechanism that can rapidly heat food while maintaining its texture, thus solving the problem that existing equipment cannot simultaneously achieve rapid heating and maintain texture.
[0004] The second objective of this invention is to provide a dual-heat-source food cooking mechanism that integrates lid-breaking water addition and steam heating, thereby solving the problems of complex equipment and the need for additional venting structures due to the existing lid-breaking water addition and steam heating being accomplished through different structures.
[0005] The third objective of this invention is to provide a dual-heat-source food cooking mechanism that cleans by inputting steam through a cleaning cup, thereby solving the problem of poor cleaning effect in existing cleaning cups that output steam through a steam input pipe.
[0006] The above technical problems are solved by the following technical solution: a dual-heat-source food cooking mechanism, including an electric furnace and a steam heating structure. The electric furnace serves as a support platform for the food container when the steam heating structure heats the food. The steam heating structure includes a vertically oriented output pipe connected to a steam source at its upper end and an output pipe lifting structure that drives the output pipe to rise and fall. In use, the electric furnace and steam heating are performed simultaneously, allowing the food to quickly reach a boil. Then, only steam heating is used to maintain the heating temperature. This improves the speed of food cooking and maintains the texture of the food. Electric furnace heating alone is fast but results in poor texture, while steam heating alone produces good texture but takes a long time to reach a boil.
[0007] Preferably, the lower end of the output pipe is provided with a pointed tip for piercing the lid of the lunchbox. This allows the lid to be pierced via the steam input pipe during steam heating, eliminating the need for a separate lid-piercing structure and reducing the number of steps.
[0008] Preferably, the lower end face of the output pipe has a downward-facing end portion outlet, and the lower circumferential surface of the output pipe has a circumferential outlet. This improves the uniformity of the steam output chamber and allows the food to tumble through the steam, preventing it from sticking to the bottom of the bowl.
[0009] Preferably, the opening direction of the peripheral outlet is horizontal. This ensures good reliability when using steam to stir food.
[0010] Preferably, the system also includes a piping control structure, a steam generator, and a water source. The piping control structure controls the output pipe to be connected to only one of the steam generator and the water source at any given time. Sharing existing steam pipes with both steam and water supply improves the structural compactness.
[0011] Preferably, a cleaning cup is also included. The pipeline control structure includes a first control valve and a pipeline connector. The pipeline connector has a first interface, a second interface, and a third interface. The first control valve is connected between the first interface and the water source. The output port of the steam generator is connected to the second interface, and the third interface is connected to the input end of the input pipe. In use, the cleaning cup outputs steam or water to clean the extended pipe, resulting in better reliability during cleaning.
[0012] Preferably, the system also includes a rotating structure for the cleaning cup and the output tube, the rotating structure being used to rotate the output tube above the cleaning cup. In use, the output tube is rotated into the cleaning cup for cleaning.
[0013] Preferably, the steam heating structure further includes a frame, and the output pipe lifting structure includes a vertical guide rod, a lifting seat sleeved on the vertical guide rod, a vertical screw threadedly connected to the lifting seat, and a lifting motor that drives the vertical screw to rotate. The vertical screw is rotatably connected to the frame, and the lifting motor and the vertical guide rod are fixed to the frame. The output pipe rotating structure includes a rotary motor mounted on the lifting seat and a swing arm connected to the output shaft of the rotary motor. The output pipe is connected to the swing arm.
[0014] Preferably, the cleaning cup has an annular cavity extending circumferentially within its peripheral wall. The annular cavity has an inlet and several outlets penetrating the inner circumferential surface of the cleaning cup. The outlets are distributed circumferentially within the cleaning cup. The cleaning cup is equipped with a drain pipe, and the inlet is connected to the outlet of a steam generator via a second control valve.
[0015] Preferably, the cleaning cup includes an upper section and a lower section. The upper end of the lower section has an outwardly flanged edge, and the upper surface of the outwardly flanged edge has a lower annular groove. The lower annular groove has several lower grooves penetrating the inner circumference of the lower section. The lower end of the upper section has an outwardly flanged edge, and the lower surface of the outwardly flanged edge has an upper annular groove. The upper annular groove has several upper grooves penetrating the inner circumference of the upper section. The outwardly flanged edge of the lower section is sealed and welded together with the outwardly flanged edge of the upper section. The upper and lower annular grooves enclose the annular cavity, and the upper and lower grooves enclose the outlet. The drain pipe is disposed on the bottom wall of the lower section. This design offers good ease of manufacturing the cleaning cup.
[0016] The utility model has the following advantages: it can quickly heat food to boiling while maintaining its taste; the water addition and steam heating are integrated into one, the structure is simple and not prone to leakage; and the cleaning effect is good when cleaning the cup and the inlet pipe (steam heating pipe).
