Description

Technical Field

[0001] The utility model relates to the technical field of steam oven fans, in particular to a steam oven fan with a thin plate stretched rear support. Background Art

[0002] The steam oven fan is a key component inside the steam oven for circulating air and regulating temperature. It rotates to promote air flow to form a hot air circulation, so that the heat is evenly distributed inside the steam oven. At the same time, it helps to regulate the temperature inside the chamber to ensure that the food is heated evenly.

[0003] There are many types of steam ovens. For example, a steam oven disclosed in Chinese patent CN216317084U includes a steam oven and other structures, which can increase the steam circulation steaming rate. However, in the use of the steam oven fan of the traditional steam oven, the traditional rear bracket assembly is usually made by casting or forging. Although this manufacturing method can meet the basic structural strength requirements, it has disadvantages such as low material utilization, high processing cost, and heavy weight. Therefore, a steam oven fan with a thin plate stretched rear bracket is proposed to solve the above problems. Utility Model Content

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] See also Figure 1-2The utility model provides the following technical solutions: a steam oven fan with a thin plate stretched rear bracket, comprising a rotor assembly 7, a cross slot pan head screw 10, a spring washer 2 and a cap nut 11. The rotor assembly 7 is externally provided with a stator winding assembly 6, and a graphite gasket 3 is provided at the connection between the rotor assembly 7 and the stator winding assembly 6. One side of the stator winding assembly 6 is sleeved with a terminal sheath 12, and the outer side of the stator winding assembly 6 is screwed with a rear bracket assembly 9 through a cross slot pan head screw 10 and the spring washer 2. The rear bracket assembly 9 is a thin plate rear bracket formed by stretching a thin plate. A shaft sleeve 1 is provided on the output shaft of the rotor assembly 7, and a front bracket assembly 8 is provided on the outer side of the output shaft of the rotor assembly 7. A fan seat 4 is provided on the outer side of the front bracket assembly 8. A fan blade 5 is screwed with a fan blade seat 4 and a cap nut 11 on one side of the front bracket assembly 8. The fan blade 5 consists of a connecting ring and a plurality of blades. A plurality of blades are provided on the outer side of the connecting ring, and the blades are symmetrically and equidistantly distributed with the midpoint of the connecting ring as the axis.

[0021] The working principle of this embodiment is as follows:

[0022] The rotor assembly 7 is connected to the motor shaft through the shaft sleeve 1. The rotation of the rotor assembly 7 drives the fan blades 5 to rotate, thereby generating wind flow. The rotation of the fan blades 5 is supported by the front bracket assembly 8 and the rear bracket assembly 9, ensuring the stability and accuracy of the fan blades 5 during high-speed rotation. The design of the rear bracket assembly 9 not only ensures the structural strength of the fan, but also realizes a lightweight design through the application of thin plate stretching technology, effectively reducing the overall weight of the fan. At the same time, since the rear bracket assembly 9 adopts thin plate stretching, the material utilization rate in its manufacturing process is improved, the processing cost is reduced, and due to the weight reduction, the start and stop of the fan are faster, which improves the response speed and working efficiency of the steam oven.

[0023] In summary, the steam oven fan with a thin plate stretched rear bracket provided by the utility model not only solves the problems of traditional steam oven fans such as heavy weight, low material utilization, and high processing cost, but also improves the overall performance and work efficiency of the steam oven, and has good market application prospects.
