Description

Technical Field

[0001] This utility model relates to the technical field of stoves, specifically an electrically controlled integrated oil-fired stove. Background Technology

[0002] A stove is a heating device used for cooking and is one of the essential cooking utensils in a kitchen. Currently, the most common stoves in kitchens are gas stoves and natural gas stoves. Gas stoves require gas cylinders to store gas, and these cylinders can explode under excessive pressure, posing a safety hazard, and are gradually being phased out. Natural gas stoves use external natural gas pipelines, eliminating the need for cylinders and avoiding the risk of explosion due to excessive pressure. However, they do pose a risk of poisoning and fire due to gas leaks. Given the numerous safety hazards of gas stoves, oil-fired stoves are quietly gaining popularity, especially those using renewable fuel oil.

[0003] Application surveys and research have revealed that the existing oil-fired stoves have their fans, oil pumps, and control circuit boards installed separately on the stove frame. The control lines are long and lack protective devices, making them prone to malfunctions during use. When a malfunction occurs and repairs are needed, only experienced personnel know how to perform the repairs. If a sudden malfunction occurs in the catering industry and no personnel are available to repair it, the stove cannot be used, disrupting normal business operations and potentially causing business losses. Summary of the Invention

[0004] The purpose of this utility model is to address the problems existing in the prior art by providing an electrically integrated oil-fired stove. This electrically integrated oil-fired stove integrates electrical control components such as a fan, oil pump, and control circuit board into an integrated power supply box. When a component fails, it can be used by simply replacing the new integrated power supply box. It is easy to disassemble and assemble, has a protective box body, short control lines, and a low failure rate.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
