Description

Technical Field

[0001] This utility model relates to the field of vending machine technology and discloses a food steaming device. Background Technology

[0002] In the fields of unmanned retail and smart catering, automatic meal vending machines need to integrate functions such as refrigerated storage, rapid heating, and automatic dispensing. Among these, the heating process is crucial for ensuring the taste and quality of the food. The heating device inside the vending machine must meet the basic requirements of being fast, uniform, and efficient to adapt to the high-frequency, fast-paced sales demands and ensure that the center temperature of the food reaches the standard and that staple foods such as rice are soft and palatable when dispensed.

[0003] Currently, the heating technology used in meal vending machines has significant limitations. While microwave heating is fast, it easily leads to uneven heating, resulting in dry and hard rice. Some devices using hot air or bottom heating plates suffer from low thermal efficiency and slow heating speed. More importantly, existing technologies struggle to achieve effective steam circulation within the sealed meal container, failing to simulate a true "steaming" effect. Furthermore, they generally lack the ability to automatically add broth or remove excess moisture during heating, impacting the final food quality. These shortcomings limit the taste and customer satisfaction of vending machine meals.

[0004] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art.

[0017] 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.

[0018] Please see Figure 1-6 This utility model provides a food steaming device, including a frame 1 and a food container 6. The frame 1 has a channel 101 for the food container 6 to move inside. A protective shell 102 is provided on the rear side of the frame 1 to house and protect internal precision components. The device includes a first pushing component 2 and a second pushing component 3 for pushing the food container 6 within the channel 101. The first pushing component 2 is located on the front side of the frame 1, and the second pushing component 3 is located inside the protective shell 102, responsible for pushing the food container 6. The device also includes two heating components 4, each containing a plug 401 that can be inserted into the food container 6 for direct internal heating. Two uprights 5 are fixedly connected inside the frame 1, and lifting structures 501 on their surfaces drive the plug 401 to move vertically, achieving precise insertion and lifting. Two steam injectors 7 are fixedly connected inside the protective shell 102 and connected to the plug 401 via steam pipes 701, responsible for providing the steam required for heating.

[0019] Specifically, the first pushing assembly 2 includes a push plate 201, a first transmission structure 202 for driving the push plate 201 to move horizontally, and a rotating structure 203 for driving the push plate 201 to rotate. The second pushing assembly 3 includes a push rod 301 and a second transmission structure 302 for driving the push rod 301 to move horizontally. The channel 101 is provided with a first heating station and a second heating station. The second pushing assembly 3 is used to receive the lunch box 6 from upstream and push it into the first heating station, and to move the lunch box 6 from the first heating station to the second heating station during the heating process. The first pushing assembly 2 is specifically used to push the lunch box 6, which is located in the second heating station after heating, out of the channel 101.

[0020] Through the above technical solution, two independent feeding assemblies driven by the first transmission structure 202, the rotating structure 203, and the second transmission structure 302, combined with a dual-heating station layout, achieve fully automated assembly line operation for heating the lunch boxes 6. Specifically, the first feeding assembly 2 avoids interference with the second feeding assembly 3 through the combined motion of the rotating lifting of the push plate 201 and the horizontal pushing motion; the second feeding assembly 3 is specifically responsible for transferring lunch boxes between the two heating stations. This design is ingenious, with coordinated movements and clear division of labor, achieving parallel heating and continuous meal dispensing at two stations within a limited space, significantly improving the space utilization and overall heating efficiency of the equipment.

[0021] Specifically, the top cover of the lunch box 6 has a lotus-shaped opening 601 for easy insertion of the plug 401. The lotus-shaped opening 601 is made of a soft sealing material, which remains closed and sealed in its natural state. When the plug 401 moves downward, it can smoothly open the valve to allow the plug 401 to be inserted, and automatically spring back to restore the sealed state after the plug 401 is pulled out.

[0022] Through the above technical solution, a lotus-shaped opening 601 is provided on the top cover of the lunch box 6, which realizes convenient connection and reliable sealing between the plug 401 and the lunch box 6. This structure not only ensures that the plug 401 can be smoothly inserted into the lunch box for direct steam and liquid injection, but also automatically closes after the plug is pulled out, effectively preventing heat and steam leakage. This improves heating efficiency and ensures the sealing and heat preservation performance of the lunch box.

[0023] Specifically, the bottom surface of the plug 401 has several steam injection holes 403 distributed in a circular pattern at equal intervals, which are used to evenly spray steam into the inside of the food container; at the same time, the side wall or bottom of the plug 401 also has two vertically arranged filling holes 402, which are used to inject soup or seasoning into different height positions inside the food container.

[0024] Through the above technical solution, the steam injection holes 403 distributed in a circle at the bottom of the plug 401 are set, which realizes the uniform injection of steam from multiple directions, making the heating area inside the food container larger and more uniform, effectively solving the problem of local overheating or heating dead corners; by setting the vertically arranged filling holes 402, layered liquid injection at different liquid levels is realized, which can not only avoid soup splashing, but also ensure that liquid seasonings penetrate evenly, greatly improving the heating effect and the taste of food.

[0025] Specifically, the upper end of the plug 401 is connected to a feed pipe 404 and an exhaust pipe 405, and the steam pipe 701 connects to the internal cavity of the plug 401. The feed pipe 404 is used to supply liquid seasoning to the plug 401, and the exhaust pipe 405 is used to expel excess moisture from the food container 6 to maintain internal pressure balance.

[0026] Through the above technical solution, the feed pipe 404, exhaust pipe 405, and steam supply pipe 701 are integrated into the plug 401, realizing the integration of steam injection, feed injection, and exhaust functions. This design allows steam heating, soup addition, and pressure regulation to be completed simultaneously through a single plug 401, which simplifies the pipeline structure, ensures the coordinated operation of each process, effectively improves heating efficiency, and avoids the problem of food quality being affected by excessive pressure or improper liquid addition inside the food container.

[0027] In use, the lunch box 6 is fed into the entrance side of the channel 101 of this device from the upstream equipment. First, the second pushing component 3 is activated, pushing the lunch box 6 into and positioning it at the first heating station. Then, the lifting structure 501 of the corresponding station drives the plug 401 of the heating component 4 to move downward and insert into the lotus-shaped opening 601 on the top cover of the lunch box 6. The steam generated by the steam injector 7 is transported to the plug 401 through the steam pipe 701 and is evenly sprayed into the lunch box 6 from the steam injection holes 403 distributed around its bottom circumference for heating. At the same time, the soup is injected into the lunch box 6 through the feeding pipe 404 and the feeding hole 402 of the plug 401. Excess gas is discharged through the exhaust pipe 405. When the current lunch box is heated at the second heating station and the lunch box at the first heating station has finished heating, the push plate 201 of the first pushing component 2 rotates and lifts to make way for the channel. The second pushing component 3 pushes the lunch box at the first heating station into the second heating station. Then, the push plate 201 is reset, and the first pushing component 2 pushes the lunch box at the second heating station out of the channel. Therefore, the first and second heating stations can alternately carry out heating and meal preparation, achieving continuous operation.
