Description

Technical Field

[0001] This utility model relates to the field of stove technology, specifically a low-noise commercial stove with a sound-absorbing air duct structure. Background Technology

[0002] In the modern catering industry, commercial stoves, as core kitchen equipment, undertake a large amount of food preparation work, and their performance directly affects the operational efficiency of catering businesses. With the large-scale development of the catering industry and the increasing demands of consumers for a better dining environment, the noise problem of commercial stoves has received growing attention. Traditional commercial stoves generate significant noise during operation, including fan operation, gas combustion, and gas flow within the ducts. This noise not only severely interferes with the normal operations of kitchen staff, but prolonged exposure can also lead to occupational health problems such as hearing damage. Furthermore, if stove noise is transmitted to the dining area, it can negatively impact the dining experience for consumers, affecting the reputation and image of the catering business.

[0003] For example, Chinese utility model patent application number 202321581592.1 discloses a commercial stove blower that is easy to install and disassemble. The main body of the stove blower can engage a rectangular block, and the elasticity provided by a compression spring can move a movable plate, allowing the insert block to directly enter the slot. A support rod can then separate the insert block from the slot, thus facilitating the installation and disassembly of the stove blower main body. However, this device still has certain shortcomings.

[0004] The fan generates a lot of noise when it is working. At the same time, the fan generates a lot of noise in the duct when it draws air in. This not only interferes with communication and cooperation among kitchen staff, but also easily causes negative emotions such as irritability and fatigue, reducing work efficiency.

[0005] Therefore, we propose a low-noise commercial stove with a sound-absorbing air duct structure to solve the problems mentioned above. Utility Model Content
