Description

Technical Field

[0001] This utility model relates to the field of elevator ventilation system technology, and in particular to a laminar flow system for purifying air inside an elevator car. Background Technology

[0002] Elevators are an essential and efficient means of transportation in modern life. They are a reliable means of transportation for occupants in high-rise residential buildings, and in places with high personnel flow, such as hospitals, elevators are often used as the main tool for transporting and transferring postoperative patients.

[0003] Modern elevators typically have fans or air conditioners installed on the top of the car, primarily to regulate the temperature inside during summer and winter. This method works by accelerating airflow or lowering the temperature. However, given the elevator environment, the frequent opening and closing of the car doors during operation results in low efficiency in temperature regulation. Furthermore, the relatively sealed and confined space inside the elevator car hinders air circulation. Since the elevator stops at each floor, passengers constantly bring fresh air into the car during these stops, creating a turbulent environment that prevents effective air purification. Bacteria that thrive in the air or are brought in by passengers are also difficult to remove and can spread throughout the car with the airflow. During pandemics or flu seasons, passengers carrying germs or those with respiratory illnesses exhaling their breath can cause cross-infection among other passengers. This is especially problematic when critically ill or post-operative patients are transported by elevator, increasing their risk of contracting other respiratory infectious diseases. Utility Model Content

[0004] In view of the shortcomings of the existing technology, this utility model provides a laminar flow system for air purification in elevator cars, which solves the problem of poor ventilation in existing elevators.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A laminar flow system for air purification in an elevator car includes an air supply system and an exhaust system. The air supply system is located at the top of the car, and the exhaust system is located at the bottom of the car. The air supply system includes a mounting box installed at the top of the car. Several air inlets are provided on the side wall of the mounting box. An air supply component and a filter component are installed sequentially from top to bottom inside the mounting box.

[0006] In this design, the air supply system is used to deliver outside air into the car from the top. After entering the car, the air flows through the entire car and is then exhausted through the exhaust system at the bottom of the car. This design accelerates the air circulation inside the car and provides good ventilation. The air supply system is designed with a filter component to filter the air entering the car, keeping the air inside the car clean and avoiding cross-infection.

[0007] Furthermore, the air supply assembly includes an air conditioning unit and a blower, with the air conditioning unit mounted on top of the mounting box and the blower located at the bottom of the air conditioning unit.

[0008] In this solution, the air conditioner is used to regulate the air temperature and improve passenger comfort; the regulated air is then pressurized by the blower and blown onto the filter assembly, so that the air has sufficient pressure to pass smoothly through the filter assembly.

[0009] Furthermore, the filter assembly includes a coarse particle filter plate, a medium particle filter plate, and a fine particle filter plate; the coarse particle filter plate, the medium particle filter plate, and the fine particle filter plate are all installed inside the mounting box, and the coarse particle filter plate, the medium particle filter plate, and the fine particle filter plate are arranged sequentially from top to bottom at the air outlet of the blower.

[0010] In this design, a coarse particulate filter is used to filter out airborne particles larger than 5 μm, a medium particulate filter is used to filter out airborne particles larger than 1 μm, and a fine particulate filter is used to filter out airborne particles larger than 0.5 μm. This design uses coarse, medium, and fine particulate filters to filter airborne particles in descending order of size, ensuring the cleanliness of the air inside the car.

[0011] Furthermore, the coarse particle filter plate is made of activated carbon filter cotton; the medium particle filter plate is made of activated carbon filter cotton or non-woven fabric; and the fine particle filter plate is made of mesh glass fiber or polypropylene fiber material.

[0012] Furthermore, the ventilation system includes a left ventilation assembly, a right ventilation assembly, and a rear ventilation assembly; the left and right ventilation assemblies are respectively installed on both sides of the car; the rear ventilation assembly is installed on the rear side of the car.

[0013] In this design, the exhaust system is distributed on the left, right and rear sides of the car to ensure that the air inside the car circulates out quickly. In practical applications, multiple exhaust components are also configured according to the size of the car to improve ventilation efficiency.

[0014] Furthermore, the right exhaust assembly includes an exhaust front cover, one side of which is mounted on the side wall of the car; the other side of the exhaust front cover is connected to an exhaust rear cover, on which an exhaust fan is mounted; both the exhaust front cover and the exhaust rear cover are provided with air outlets.

[0015] In this design, the exhaust front cover and exhaust rear cover protect the exhaust fan from foreign objects entering and damaging it.

[0016] Furthermore, the car includes a car roof, car walls are connected around the car roof, and a car floor is connected to the bottom of the car walls; An air inlet is provided on the car roof, and the air supply system is installed at the air inlet position on the car roof; Air vents are provided on the car walls, and the exhaust system is installed at the air vent locations on the car walls.

[0017] In this design, mesh vents are provided on the side walls of the car where the air supply and exhaust systems are installed. The purpose of these vents is to allow air to pass smoothly through the car and ensure air circulation within the car.

[0018] Furthermore, the diameter of the air vents on the car wall is less than 10mm.

[0019] In this design, the aperture is less than 10mm to prevent children's or adults' fingers from accidentally entering and causing danger.

[0020] The beneficial effects of this utility model are: The laminar flow system for air purification in elevator cars provided by this utility model includes an air supply system at the top of the car, where an air conditioning unit regulates the air temperature to ensure passenger comfort. A blower is located at the bottom of the air conditioning unit to pressurize the air. The pressurized air then passes through a filter assembly, which removes particulate matter in stages. An exhaust system located at the bottom of the car exhausts air outwards, creating negative pressure in the bottom area. This causes clean air to flow vertically in a laminar manner from top to bottom within the car. Passengers' exhaled air is also orderly discharged downwards through the exhaust system, maintaining clean air within the car, improving airflow, and thus reducing the risk of cross-infection of respiratory diseases within the car.
