Especially in hot summer or cold winter, temperature regulation and air quality control in elevators become a major problem. Therefore, developing a device that can quickly generate a large amount of flowing gas and achieve rapid ventilation in elevators is of great significance to improving the comfort and air quality of elevators.

[0006] An air outlet with a guide plate provided at the upper end of the inner compartment is called an air outlet with a guide plate, and the air outlet with a guide plate is connected to the inner compartment and the air flow channel; an air inlet with a guide plate provided at the lower end of the inner compartment is called an air inlet with a guide plate, and the air inlet with a guide plate is connected to the inner compartment and the air flow channel;
[0007] An air duct loop is provided between the outer compartment and the inner compartment and is bent and fitted to the outer wall of the inner compartment; the refrigeration air conditioner has an evaporator and an air conditioner outdoor unit; the evaporator is arranged in the air duct loop and is located at the bottom, and a fan for driving the air flow is also provided in the air duct loop; an array of through holes connecting the inner compartment and the air duct is provided on the wall of the inner compartment; the outdoor unit of the refrigeration air conditioner is arranged at the bottom of the outer compartment.
[0008] In the utility model, an air flow channel is arranged inside and outside the car, the air inlet end of the air flow channel is connected to the air in the elevator shaft through the through hole of the outer car bottom shell, the air outlet end of the air flow channel is connected to the cavity between the sealing plate and the outer car top wall through the through hole of the sealing plate, the outer car top wall shell is provided with an air outlet connected to the elevator shaft, the air outlet is connected to a high-speed turbine fan, and the air in the cavity is discharged into the elevator shaft through the high speed and large air volume characteristics of the high-speed turbine fan.
[0009] An air inlet and an air outlet are provided on the inner compartment, the air inlet and the air outlet are connected to the air flow channel, and the air inlet and outlet are guided by a guide plate.
[0010] When the guide plate is arranged at one side of the air flow channel, the air in the air flow channel is deflected by the guide plate and enters the inner compartment of the car, thereby bringing fresh air into the inner compartment.
[0011] When the guide plate is set on one side of the inner car, the high-speed air flowing in the air flow channel forms a negative pressure effect relative to the air flow in the inner car, and then draws the stale air in the inner car into the air flow channel, and finally is discharged into the elevator shaft by the high-speed turbine fan in the cavity, thereby realizing the replacement of the air in the car. The whole ventilation process does not cause a strong impact on the passengers, and the ventilation completely leaves no dead corners, thereby improving the air quality in the elevator car.
[0012] In the utility model, a refrigeration air conditioner is also arranged under the elevator car. The evaporator of the refrigeration air conditioner is arranged between the outer compartment and the inner compartment at the bottom end of the elevator car, and the closed space between the outer compartment and the inner compartment forms an air duct loop that bends and fits around the inner compartment to prevent cold air from escaping, resulting in low refrigeration efficiency and waste of energy. At the same time, there is an array of through holes between the air duct loop and the inner compartment, so that cold air can enter the inner compartment. When the temperature and humidity in the elevator car are too high, cooling and dehumidification are achieved through the refrigeration air conditioner to improve the comfort level in the elevator car.
[0013] Furthermore, a filter cover is provided below the air inlet of the outer compartment, and the filter cover includes four side walls, the lower ends of the side walls have inward-turned flanges, and the side walls are provided with fence-like strip holes.
[0014] In the utility model, the filter cover is used to set the filter element for filtering. The lower ends of the four side walls have inwardly folded edges, which are used to hold the filter layer of the filter element. The four side walls of the filter cover are provided with fence-like strip openings to allow air to flow smoothly through the filter cover. The filter cover is set below the outer compartment. The purpose of this design is to facilitate the replacement of the filter element material in the filter cover.
[0015] For further optimization, a filter layer is arranged in the filter cover, and the filter layer is arranged with a coarse filter layer, an activated carbon layer and a fine filter layer; the coarse filter layer is arranged on the bottom layer of the filter cover, and on four coarse filter sides arranged along the side wall of the filter cover; the activated carbon layer is arranged in the area surrounded by the coarse filter, and the height of the activated carbon layer is the same as the height of the coarse filter side; the fine filter layer is arranged on the activated carbon layer and the four coarse filter sides.
[0016] In the utility model, the function of the coarse filter is to intercept large suspended particles floating in the air, such as catkins, dust, etc., and the other function is to coat the activated carbon particles to prevent the loss of the activated carbon particles. The function of the activated carbon is to adsorb various harmful substances in the air, which can more effectively filter PM2.5 in the air and improve the air quality in the elevator car. The function of the fine filter is to intercept tiny suspended particles floating in the air, and the other function is to coat the activated carbon particles to prevent the loss of the activated carbon particles.
[0017] Further preferably, the ratio of the thickness of the fine filter layer to the thickness of the coarse filter layer is 1:1-5.
[0018] In the present invention, the particle size of the particulate matter intercepted by the coarse filter is larger than that of the particulate matter intercepted by the fine filter. Therefore, the life of the coarse filter is shorter during use, and the number of times the coarse filter element is replaced will inevitably exceed the number of times the fine filter element is replaced. Therefore, appropriately increasing the thickness of the coarse filter element layer can reduce the number of times the coarse filter is replaced to maintain a replacement frequency equivalent to that of the fine filter, which is beneficial to reducing the operating cost of the elevator and increasing the operating time of the elevator.
[0019] Further preferably, the coarse filter layer uses PP cotton with a minimum filtration of 30 μm; the fine filter layer uses PP cotton with a minimum filtration of 10 μm; the activated carbon uses granular activated carbon, the mesh number of the activated carbon particles is 18 to 35 meshes, and the activated carbon particles are filtered through 5 to 10 kg / cm 2 pressure compaction.
[0020] In the utility model, the filter layer is used to filter suspended particles in the air. The particle size of the particles in the atmosphere ranges from 0.001μm to 1000μm. Generally, suspended particles with a particle size greater than 50μm are quickly settled to the ground by gravity, and suspended particles less than 50μm not only stay in the atmosphere for a long time, but also migrate over a long distance. Therefore, the air filter of the elevator car needs to filter suspended particles of this particle size. The coarse filtration range is 30μm, and the fine filtration range is 10μm. After two-stage PP cotton filtration, more than 90% of suspended particles can be filtered. For tiny suspended particles with a particle size less than 10μm, the adsorption capacity of activated carbon can be used for filtration. The activated carbon filter element can filter bacteria and viruses, and can improve the air quality in the elevator car.
[0021] In the present invention, there are relatively large gaps between the activated carbon particles, so compaction is required. However, too tight compaction will result in poor air circulation, so the pressure needs to be controlled within a certain range.
[0022] Furthermore, the motor of the high-speed turbine fan adopts a permanent magnet suspension motor.
[0023] The characteristic of permanent magnet suspension motor is that permanent magnet suspension rotation replaces bearing rotation, eliminating the problem of heat generated by friction between the rotor and the bearing during high-speed rotation. After solving the problem of heat generated by friction, the rotor speed can be increased as much as possible, while the working noise is reduced. Since friction loss is reduced, the service life of the fan is also greatly increased.
[0024] Furthermore, the blades of the high-speed turbine fan are made of glass fiber reinforced plastic or carbon fiber composite material.
[0025] The blades of high-speed turbine fans are made of glass fiber reinforced plastic or carbon fiber composite materials, both of which are lightweight and high-strength, ensuring that the blades have sufficient strength and stability when the motor rotates at high speed.
[0026] Furthermore, a sealing gasket is provided between the high-speed turbine fan and the outer chamber, and the sealing gasket is a rubber sealing gasket.
[0027] In the utility model, a sealing pad is arranged between the high-speed turbine fan and the outer chamber, so that the suction force of the high-speed turbine fan can be enhanced and the noise when the high-speed turbine fan is running can be reduced.
[0028] Furthermore, a temperature sensor is also provided in the elevator car, and the temperature sensor has a temperature signal output interface; a humidity sensor is also provided in the elevator car, and the humidity sensor has a humidity signal output interface; a control system is also provided in the elevator car, and the control system has a temperature signal input interface, a humidity signal input interface, a switch control output interface, and a start control output interface; the temperature signal output interface is electrically connected to the temperature signal input interface, and the humidity signal output interface is electrically connected to the humidity signal input interface; the switch control output interface is electrically connected to the switch control input end of the high-speed turbine fan, and the start control output interface is electrically connected to the start control input end of the refrigeration air conditioner.
[0029] In the utility model, the control system monitors the temperature, humidity and other parameters in the elevator car in real time by accessing the temperature sensor and the humidity sensor, and automatically adjusts the speed of the fan according to these parameters, and starts the refrigeration air conditioner to cool down and dehumidify, thereby improving the environmental comfort in the elevator car.
[0030] The utility model provides an air flow channel for air to flow through in the car, one end of the air flow channel is connected to the elevator shaft, and the other end is provided with a high-speed turbine fan, a large amount of flowing gas is generated by the high-speed turbine fan, an air inlet and an air outlet are provided between the air flow channel and the inner car, the air inlet introduces fresh air from the air flow channel under the action of the guide plate, the high-speed flowing air in the air flow channel forms a negative pressure effect relative to the air in the inner car, and then the air in the inner car is sucked into the air flow channel, and discharged into the elevator shaft through the high-speed turbine fan, completing the renewal of the air in the inner car, the new air is filtered and adsorbed multiple times, harmful suspended matter and harmful substances such as bacteria and viruses in the air are eliminated, the air quality in the elevator car is improved, and the control system is used to realize intelligent automatic adjustment of the speed and ventilation volume of the fan, and the refrigeration air-conditioning can be started according to parameters such as temperature and humidity in the elevator to provide a comfortable riding environment.

[0055] In this embodiment, the filter cover 4 is used to set the filter element for filtering. The lower ends of the four side walls have inwardly folded flanges 41, and the flanges 41 are used to hold the filter layer of the filter element. The four side walls of the filter cover 4 are provided with fence-like strip openings to allow air to flow smoothly through the filter cover 4. The filter cover 4 is arranged below the outer compartment 1, and the purpose of such design is to facilitate the replacement of the filter element material in the filter cover 4.
[0056] Further optimization is performed, a filter layer is arranged in the filter cover 4, and the filter layer is provided with a coarse filter layer 14, an activated carbon 15 layer and a fine filter layer 16; the coarse filter layer 14 is arranged on the bottom layer of the filter cover 4, and on four coarse filter sides arranged along the side wall of the filter cover 4; the activated carbon 15 layer is arranged in the area surrounded by the coarse filter, and the height of the activated carbon 15 layer is the same as the height of the coarse filter side; the fine filter layer 16 is arranged on the activated carbon 15 layer and the four coarse filter sides.

Therefore, the air filter of the elevator car needs to filter particulate suspension of this particle size. The coarse filtration range is 30μm, and the fine filtration range is 10μm. After two-stage PP cotton filtration, more than 90% of the particulate suspension can be filtered.

[0064] The characteristic of permanent magnet suspension motor is that permanent magnet suspension rotation replaces bearing rotation, eliminating the problem of heat generated by friction between the rotor and the bearing during high-speed rotation. After solving the problem of heat generated by friction, the rotor speed can be increased as much as possible, while the working noise is reduced.
