Description

Technical Field

[0001] This utility model belongs to the field of commercial kitchen equipment technology, and more specifically, it relates to an impeller used in commercial steam ovens. Background Technology

[0002] As a core component of commercial kitchen equipment, the impeller of a steam oven plays a crucial role in guiding airflow, promoting heat transfer, and ensuring uniform temperature and steam distribution within the oven. In commercial multi-functional steam ovens, the impeller's performance directly impacts cooking efficiency and food quality. However, existing impellers suffer from several shortcomings in design and material application, making it difficult to meet the high-load, high-efficiency demands of commercial kitchens.

[0003] I. Significant Performance Shortcomings: In the actual application scenarios of commercial steam ovens, the complex cooking needs and extremely high workload place extremely high demands on the impeller performance. However, currently common impellers are prone to deformation and wear under complex operating conditions of high temperature, high humidity, and frequent start-ups and stops. This not only leads to turbulent airflow, severely affecting the uniformity of temperature and steam distribution inside the steam oven, but also reduces cooking efficiency and food quality. For example, when baking a large quantity of bread, if the impeller performance is poor, uneven temperature will occur inside the oven, causing some bread to be overbaked while others are underbaked. This not only affects the overall quality of the food but also results in waste of raw materials and reduced production efficiency.

[0004] II. Limitations in Structural Design: Traditional impellers have a relatively simple blade design, which cannot efficiently guide airflow, resulting in low heat transfer efficiency. This design deficiency prolongs cooking time, increases energy consumption, and is detrimental to energy conservation, emission reduction, and cost reduction in commercial kitchen equipment. Furthermore, the impeller lacks effective reinforcement and airflow guidance structures, leading to poor stability and susceptibility to damage during long-term use. This not only increases maintenance costs but also affects the normal operation and cooking efficiency of the steam oven. In addition, traditional impellers typically use a single-layer design at the bottom, which is not conducive to heat insulation and structural stability. In commercial environments, this design cannot withstand the high-intensity usage demands, easily leading to impeller deformation and damage.

[0005] Therefore, this utility model provides an impeller for use in commercial steam ovens. Utility Model Content

Specific structures can be described with reference to the accompanying drawings of the patent application.

[0037] This utility model provides an impeller for use in commercial steam ovens. Please refer to [link / reference]. Figures 1 to 4 As shown, it includes a blade assembly 100, an end cap 200, and a connecting seat 300. The blade assembly 100, the end cap 200, and the connecting seat 300 are a split structure. The upper end of the blade assembly 100 is connected and fixed to the end cap 200, and the lower end of the blade assembly 100 is connected and fixed to the connecting seat 300.

[0038] The blade assembly 100 includes a plurality of positive blades 110 and a plurality of negative blades 120. The plurality of positive blades 110 and the plurality of negative blades 120 are arranged sequentially at equal intervals on the connecting seat 300. The plurality of positive blades 110 and the plurality of negative blades 120 are arranged radially in a petal shape around the center of the connecting seat 300. The positive blades 110 and the negative blades 120 are arranged in a logarithmic manner. A pair of positive blades 110 and negative blades 120 are distributed in a figure-eight shape. In this embodiment, there are three sets of both positive blades 110 and negative blades 120.

[0039] The connecting seat 300 has a shaft hole 310 for connecting the motor drive shaft at its center. The connecting seat 300 has a double-layer structure, including an upper connecting plate seat 320 and a lower connecting plate seat 330. The upper connecting plate seat 320 and the lower connecting plate seat 330 are connected. The upper connecting plate seat 320 and the lower connecting plate seat 330 are evenly spaced and provided with a plurality of reinforcing grooves 321. In this embodiment, the upper connecting plate seat 320 and the lower connecting plate seat 330 are provided with six sets of reinforcing grooves 321. These grooves greatly enhance the structural strength of the impeller without significantly increasing the weight, and can effectively resist the stress generated by high-speed rotation and complex airflow. The lower connecting plate is provided with a plurality of air guide holes 331 at equal intervals around the shaft hole 310. In this embodiment, the air guide holes 331 are provided with six sets. The air guide holes 331 can accurately guide the airflow, optimize the airflow direction in the air duct, improve the heat transfer efficiency, and shorten the cooking time.

[0040] It should be noted that the blade assembly 100 adopts a positive and negative combination. The positive blade 110 is responsible for quickly sending out the airflow, while the negative blade guides and rectifies the airflow, so that the airflow forms a more uniform and stable circulation in the steam oven, effectively improving the problem of uneven temperature and steam distribution, and significantly improving the consistency of cooking.

[0041] In addition, the connecting seat 300 adopts a double-layer structure. The upper connecting plate seat 320 is used to insulate heat from being transferred to the motor and protect the motor from running normally.

[0046] The upper end face of the upper connecting plate seat 320 of the end cover 200 is provided with an annular groove 322 centered on the shaft hole portion 310. The annular groove 322 of the upper connecting plate seat 320 penetrates the reinforcing groove 321 of the upper connecting plate seat 320.

[0047] The shaft hole portion 310 of the connecting seat 300 is shaped as two circular rings connected at the same center. Several mounting slots 311 are evenly spaced at the outer edge of the upper circular ring of the shaft hole portion 310 of the connecting seat 300. In this embodiment, three sets of mounting slots 311 are provided.

[0048] The mounting slot 311 is rectangular.

[0049] The end cap 200, positive blade 110, negative blade 120, upper connecting plate seat 320, and lower connecting plate seat 330 are all integral parts made of titanium alloy. Titanium alloy has high strength, low density, and excellent high temperature resistance and corrosion resistance. It can maintain a stable state under the harsh working conditions of the steam oven, which greatly improves the durability of the impeller and effectively reduces damage and maintenance caused by material problems.
