Description

Technical Field

[0001] This utility model relates to the field of ship equipment structure, specifically a ship kitchen ventilation system. Background Technology

[0002] With the development of the shipping industry, the safety, comfort, and environmental friendliness of ships have received increasing attention. As a crucial living and working space for crew members, the performance of the ventilation system in the ship's galley directly impacts the galley's environmental quality, crew health, and the safe operation of the vessel. Simultaneously, to meet the requirements of green and energy-efficient ships, reducing the energy consumption of ventilation systems has become an important research direction.

[0003] Currently, shipboard kitchen ventilation systems typically employ a combination of traditional ceiling-mounted fume hoods and exhaust fans. The fume hoods are installed at the top of the kitchen, and the exhaust fans expel stale air. However, this method has several problems. For example, airflow is difficult to reach the lower and middle parts of the kitchen, causing fumes and steam to easily adhere to work surfaces and floors. This not only affects kitchen hygiene but can also breed bacteria and corrode the ship's structure. Furthermore, traditional exhaust systems are ineffective at filtering fumes and collecting grease, easily leading to pipe blockages and fire hazards.

[0004] Generally, the required ventilation volume is first determined based on the size of the kitchen, the number of equipment, and the number of personnel. Then, appropriate fans and fume hoods are selected. The fume hood is installed on the ceiling of the kitchen, and the fan is connected to the fume hood through ducts. When the fan is turned on, the stale air in the kitchen is drawn into the fume hood and then discharged outside the ship through ducts. Some systems have simple filtration devices installed in the ducts, but the filtration effect is limited, and there is a lack of effective measures for collecting and treating oil sludge.

[0005] Traditional ventilation systems typically have only one vent, which cannot treat gases at multiple points in different work areas of the kitchen. This results in uneven ventilation, with some areas still having residual fumes and odors. At the same time, grease can easily accumulate in the pipes, increasing the risk of pipe blockage and fire, as well as increasing the difficulty and cost of cleaning and maintenance. Utility Model Content

[0006] Based on this, the purpose of this utility model is to provide a ship kitchen exhaust system to solve the technical problems of single-point kitchen ventilation, poor filtration and oil collection effects, and inconvenient cleaning.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a marine kitchen ventilation system, comprising an exhaust fan body, the exhaust fan body being configured in an inverted "Y" shape, a pair of mounting slots symmetrically opened at the bottom of the exhaust fan body, a pair of fan mounting ports being provided in the mounting slots, a mounting bracket being provided at the bottom of the mounting slots to cooperate with the fan mounting ports, a filter screen body being provided in the mounting bracket, one side of the mounting bracket extending outside the exhaust fan body, a handle being provided on the side of the mounting bracket outside the exhaust fan body, and an oil collection groove being provided at the bottom of the exhaust fan body between the pair of mounting slots.

[0008] By adopting the above technical solution, the main functions of the exhaust system can be achieved, and the mounting bracket makes it easier to recycle the oil accumulated on the filter body.

[0009] The present invention is further configured such that an exhaust connection port is provided on the top of the exhaust fan body, the exhaust connection port extends into the interior of the exhaust fan body, and a collection tray is provided inside the exhaust fan body in conjunction with the exhaust connection port, and the collection tray has an opening.

[0010] By adopting the above technical solution, oil pollution can be recovered and collected, preventing oil pollution from accumulating and affecting the ventilation system.

[0011] The present invention is further configured such that a connecting pipe is provided at the bottom of the exhaust fan body, and the connecting pipe is connected to the oil collection trough.

[0012] By adopting the above technical solution, the oil sludge is recovered and collected in the oil collection tank.

[0013] The present invention is further provided that a conical filter screen is provided inside the exhaust fan body in conjunction with a collection tray.

[0014] By adopting the above technical solution, the oil recovery effect is ensured through the use of a conical filter screen.

[0015] The present invention is further configured such that the top of the oil collection tank is provided with a plurality of connecting buckles, and the bottom of the exhaust fan body is provided with a slot in cooperation with the connecting buckles.

[0016] By adopting the above technical solution, the oil collection tank can be quickly installed and disassembled.

[0017] The present invention is further provided that the bottom of the exhaust fan body is provided with a leakage groove in conjunction with the mounting bracket, and the bottom of the exhaust fan body is provided with a collection groove in conjunction with the leakage groove.

[0018] By adopting the above technical solution, dirt on the filter screen can be collected into the collection tank when the mounting bracket is pulled.

[0019] The present invention is further configured such that a vent pipe is provided on the top of the exhaust fan body in conjunction with the exhaust connection port, and a through hole is provided on the top of the vent pipe.

[0020] By adopting the above technical solution, external pipelines are connected through ventilation pipes and through holes.

[0021] In summary, the present invention has the following main advantages:

[0022] This utility model utilizes a ship's kitchen ventilation system with an inverted "Y"-shaped exhaust fan body and two air vents. These vents can be positioned at different work locations depending on the kitchen layout, enabling multi-point gas treatment. Simultaneously, the filter body and conical filter effectively filter pollutants such as oil fumes and particulate matter, ensuring fresh air in the kitchen and creating a comfortable working environment for staff.

[0023] This invention features an oil collection tank in the system that is easily installed and disassembled via connecting clips. It can collect oil sludge falling from the bottom of the conical filter screen and output from the connecting pipe. The handle design of the mounting bracket facilitates movement, allowing the exhaust fan body to scrape dirt from the surface of the conical filter screen into the leakage tank for collection. This greatly reduces cleaning difficulty, improves maintenance efficiency, and ensures long-term stable operation of the system. Attached Figure Description

This arrangement allows for two ventilation ports, enabling the ventilation ports to be placed in different working positions in the kitchen, thus improving multi-point gas treatment of the kitchen environment. By installing a fan within the fan mounting ports 11, the airflow is driven, thus treating the air in the kitchen environment.

[0032] Furthermore, an oil collection tank 2 is provided at the bottom of the exhaust fan body 1 between a pair of mounting slots 10, and an exhaust connection port 12 is provided at the top of the exhaust fan body 1, extending into the interior of the exhaust fan body 1. A collection tray 13 is provided inside the exhaust fan body 1 in conjunction with the exhaust connection port 12, and an opening 14 is provided on the collection tray 13. A conical filter screen 15 is provided inside the exhaust fan body 1 in conjunction with the collection tray 13. In actual use, the gas is filtered through the conical filter screen 15. The conical filter screen 15 ensures that a certain amount of oil can drip from the conical filter screen 15, be collected by the collection tray 13, and then discharged through the opening 14. Correspondingly, a connecting pipe 6 is provided at the bottom of the exhaust fan body 1, through which the output is carried out. At the same time, the connecting pipe 6 is connected to the oil collection tank 2, through which the collected oil is collected.

[0033] The top of the oil collection tank 2 is provided with several connecting buckles 16, and the bottom of the exhaust fan body 1 is provided with a slot 17 to cooperate with the connecting buckles 16, so as to realize the quick installation and disassembly of the oil collection tank 2.
