Description

Technical Field

[0001] This utility model relates to the field of rice steamer technology, and in particular to a rice steamer with anti-condensate backflow function. Background Technology

[0002] A rice steamer is a kitchen appliance that uses steam heating to cook rice. It is widely used in canteens, restaurants, fast food outlets, and factories, among other catering establishments. This equipment typically consists of a steam generator, a steaming cabinet, and a steaming tray or steaming box. It heats water to produce steam, which is then evenly distributed around the rice grains through a closed structure, ensuring even heating and thorough cooking, thus improving the taste and quality of the rice. Compared to traditional open-flame cooking, rice steamers offer advantages such as energy efficiency, ease of operation, safety, and high capacity. They are particularly suitable for large-scale centralized cooking needs and are an indispensable piece of equipment in modern commercial kitchens.

[0003] In existing large-capacity commercial rice steamers, a closed steam circulation system is typically used to improve cooking efficiency, with exhaust vents on the top or side of the machine to expel excess steam. However, condensate generated during cooking tends to accumulate at the top and exhaust channels, and has a tendency to flow back into the cooking cavity. This results in locally overly moist rice, causing grains to stick together and clump, severely affecting the taste of the finished rice. Simultaneously, impurities that may be carried in the returning condensate can accumulate on the top and side walls of the machine over time, promoting metal surface corrosion and increasing the difficulty of daily cleaning and maintenance, ultimately shortening the equipment's lifespan.

[0004] Therefore, existing technologies still have limitations in practical applications, such as insufficient anti-condensate backflow performance, high maintenance costs, and unstable finished product quality. Based on this, we propose a rice steamer with anti-condensate backflow function to solve the aforementioned problems. Utility Model Content

[0011] Optionally, the roller is matched with the guide groove structure, and the roller and the guide groove are in rolling contact.

[0012] In summary, this utility model has at least one of the following beneficial effects: 1. The rice steaming equipment designed in this scheme effectively filters impurities and guides condensate water smoothly into the drain pipe and out of the equipment by installing a return plate on the top of the steaming cabinet and connecting it to the return cavity, and setting filter components and inclined guide plates at the opening of the return cavity. This achieves precise control of condensate water. This structural design not only successfully solves the problem of localized excessive moisture and rice grain sticking together caused by condensate water return in the existing technology, ensuring that the rice is soft and fluffy with distinct grains, thus improving the quality of the finished rice and meeting people's demand for high-quality rice, but also effectively avoids the long-term deposition of impurities on the top and sides of the machine body, thereby reducing the risk of corrosion on the metal surface, reducing the workload and frequency of daily cleaning and maintenance, extending the service life of the equipment, and improving the reliability and stability of the equipment.

[0013] 2. The rice steaming equipment designed in this scheme, by installing rollers at both ends of the rice steamer and matching them with the guide groove structure on both sides of the steaming cavity for rolling contact, allows the rice steamer to move smoothly and steadily in and out of the steaming cavity. This facilitates the placement and removal of rice and other food by operators, greatly improving the ease of use of the equipment. At the same time, this rolling contact structure design ensures that the normal circulation of steam in the steaming cavity is not disturbed while ensuring the normal steaming function of the rice steamer, and does not affect the drainage path of condensate, further strengthening the control of condensate. This achieves stable operation of the entire rice steamer during the steaming process, improves the quality of cooked rice, and brings higher work efficiency and a better user experience to commercial kitchens.

[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] Example: Refer to Figures 1 to 7 This utility model provides an embodiment of a rice steamer with anti-condensate backflow function, including a rice steamer cabinet 1. A drain pipe 2 is provided on one side of the exterior of the rice steamer cabinet 1. A sealed door 3 is installed on one side of the rice steamer cabinet 1. A steaming cavity 4 is opened inside the rice steamer cabinet 1. Multiple sets of rice steaming trays 5 are also provided inside the steaming cavity 4. Steaming heaters 6 are provided on both sides of the steaming cavity 4. Multiple sets of guide grooves 7 are equidistantly opened on one side of each set of steaming heaters 6. Steam is generated by the steaming heaters 6 inside the rice steamer cabinet 1. When the steam rises to the top of the rice steamer cabinet 1, it encounters... The condensate forms as cold water and flows along the return top plate 8 into the return cavity 9. The filter element 10 at the opening of the return cavity 9 filters impurities, preventing them from accumulating and settling inside the return cavity 9, which could lead to insufficient space inside the return cavity 9 and blockage of the inlet port of the drain pipe 2. By installing a guide plate 12 at an angle inside the return cavity 9, the filtered condensate can be smoothly guided into the drain pipe 2 and discharged outside the equipment. This avoids the condensate from flowing back into the cooking cavity 4 at the top or exhaust channel, thus achieving effective condensate discharge.

[0019] A reflux top plate 8 is installed at an angle on the top of the rice steamer 1. A reflux cavity 9 is opened on the side of the rice steamer 1 near the reflux top plate 8. A filter component 10 is also provided at the opening of the reflux cavity 9. Through the reflux top plate 8 installed at an angle on the top of the rice steamer 1, the reflux top plate 8 is connected to the reflux cavity 9 on one side. When the steam generated by the rice steamer 1 is powered on and rises to the top, it encounters cold water and forms condensate. The condensate can be collected in the reflux cavity 9 along the inclination of the reflux top plate 8. This can prevent the condensate adhering to the top of the rice steamer 1 from dripping onto the surface of the rice. Positioning slots 11 are provided on both sides of the opening of the reflux cavity 9. A guide plate 12 is also installed at an angle inside the reflux cavity 9. The guide plate 12 installed at an angle inside the reflux cavity 9 can further guide the condensate collected inside the reflux cavity 9, so that the collected condensate can flow smoothly into the drain pipe 2 and be discharged outside the equipment.

[0020] The filter component 10 includes a filter screen 13, with positioning plates 14 installed on both sides of the filter screen 13. The positioning plates 14 and positioning slots 11 are structurally matched and are engaged in a snap-fit ​​manner. Through the snap-fit ​​structure between the positioning plates 14 and positioning slots 11, the filter screen 13 can be locked and positioned at the opening of the return cavity 9. The return cavity 9 can be disassembled, connected, repaired, and replaced according to the usage of the filter screen 13. A handle 15 is installed on one side of the rice steamer 5, and several sets of rollers 16 are rotatably connected to both ends of the rice steamer 5. The handle 15 and roller 16 added to the rice steamer 5 make it easy for users to grasp and pull out the rice steamer 5. The roller 16 is matched with the guide slide 7, and there is a rolling contact between the roller 16 and the guide slide 7. Through the structural design of the rolling contact between the roller 16 and the guide slide 7, the rice steamer 5 can be smoothly adjusted and moved smoothly in the guide slide 7, thus providing a smoother operating experience when pulling out the rice steamer 5. At the same time, it ensures the stability of the rice steamer 5 during the movement, prevents equipment damage or inconvenience caused by uneven pulling out, and effectively improves the overall performance and reliability of the equipment.

[0021] Working Principle: The rice steaming equipment designed in this scheme, by installing a return top plate 8 on the top of the rice steamer 1 and connecting it to the return cavity 9, can effectively collect and guide the condensate generated during the steaming process into the return cavity 9, achieving initial isolation between the condensate and the steaming cavity 4. The filter component 10 set at the opening of the return cavity 9 can filter out impurities in the condensate, preventing impurities from accumulating and settling inside the return cavity 9, which would lead to insufficient space inside the return cavity 9 and blockage of the water inlet port of the drain pipe 2. The guide plate 12 set at an inclination inside the return cavity 9 can further guide the condensate collected inside the return cavity 9, so that the collected condensate can flow smoothly into the drain pipe 2 and be discharged outside the equipment, thereby completely avoiding the situation where condensate accumulates at the top or exhaust channel and flows back into the steaming cavity 4, ensuring the dryness and taste of the rice in the steaming cavity 4.

[0022] The rice steaming equipment designed in this scheme, by installing rollers 16 at both ends of the rice steamer 5 and matching and rolling contacting the guide grooves 7 equally spaced on both sides of the steaming cavity 4, allows the rice steamer 5 to smoothly enter and exit the steaming cavity 4. This facilitates the placement and removal of rice and other food by the operator, improving the ease of use of the equipment. At the same time, this rolling contact design does not affect the normal circulation of steam in the steaming cavity 4, nor does it interfere with the drainage path of condensate. Thus, while ensuring the normal steaming function of the rice steamer, it also effectively controls condensate, ensuring stable operation of the entire rice steamer during the steaming process and improving the quality of the cooked rice.

[0023] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
