Description

Technical Field

[0001] This utility model relates to food cooking and processing appliances, and more particularly to a steam heating mechanism that integrates heating and water addition. Background Technology

[0002] To improve the convenience of dining, the applicant has designed a food vending machine for food preparation and vending, with publication number CN112716256A and title "A Steamed Food Machine". Existing food preparation and vending machines require a separate design for adding water to foods that need water added just before cooking. This involves piercing the lid to add water, and then inserting a steam input pipe through the pierced hole during the heating and cooking process. This method not only results in a long food preparation time but also causes significant air leakage due to the mismatch between the steam input pipe and the hole in the lid. In such cases, a lid needs to be placed over the hole, and steam needs to be extracted to remove the overflowing steam, leading to a complex equipment structure. Utility Model Content

[0003] The first objective of this utility model is to provide a steam heating mechanism that integrates water addition and steam heating by breaking the lid, which solves the problems of existing equipment that uses different structures for water addition and steam heating, resulting in complex equipment and steam overflow during heating, requiring a separate structure for venting.

[0004] The second objective of this invention is to provide a steam heating mechanism that integrates heating and water addition, which uses steam input from a cleaning cup for cleaning. This solves the problem of poor cleaning effect in existing cleaning cups that use steam input pipes for cleaning.

[0005] The above technical problems are solved by the following technical solution: a steam heating mechanism integrating heating and water addition, characterized in that it includes an output pipe, an output pipe lifting structure for driving the output pipe to rise and fall, a pipeline control structure, a steam generator, and a water source. The pipeline control structure is used to control that the output pipe is connected to only one of the steam generator and the water source at any given time. The lower end of the output pipe is provided with a pointed tip for piercing the lid of a lunchbox. This allows the lid to be pierced using the steam input pipe during steam heating, eliminating the need for a separate lid-piercing structure and reducing the processing steps. It also shares an existing steam pipe with both steam and water addition, improving the compactness of the structure.

[0006] 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.

[0007] Preferably, the opening direction of the peripheral outlet is horizontal. This ensures good reliability when using steam to stir food.

[0008] Preferably, the system also includes a rotating structure for the cleaning cup and the output pipe. The pipe control structure includes a first control valve and a pipe connector. The pipe 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. The rotating structure is used to rotate the output pipe above the cleaning cup. In use, the cleaning cup outputs steam or water to clean the extended pipe, resulting in better cleaning reliability.

[0009] 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.

[0010] 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.

[0011] 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.

[0012] The utility model has the following advantages: the water addition and steam heating are integrated into one, the structure is simple and it is not easy to cause air leakage; the cleaning effect is good when cleaning the cup and the inlet pipe (steam heating pipe).
