Description

Technical Field

[0001] This application relates to the field of elevator ventilation equipment technology, specifically an automatic ventilation and air exchange device for elevators. Background Technology

[0002] With the increasing number of high-rise buildings in cities, elevators have become an indispensable vertical transportation tool for people. An elevator is a vertical lifting machine powered by an electric motor, equipped with a box-shaped cabin, used for carrying people or goods in multi-story buildings. It is widely used in residential buildings, office buildings, hospitals, shopping malls and other places, which greatly improves people's living efficiency.

[0003] During elevator use, the elevator car is a relatively enclosed space with poor air circulation, which can easily accumulate odors, bacteria and viruses. The air quality problem is more prominent, especially when there are many people. Therefore, it is necessary to install automatic ventilation and air exchange devices inside the elevator to ventilate and exchange the air inside the elevator.

[0004] Elevator ventilation and air exchange devices are important equipment used to improve the air quality in elevator cars and shafts. By operating the fan, fresh air from outside flows in through the air inlet and is transported into the car through the air duct. At the same time, stale air in the car is discharged from the air outlet, thus achieving air exchange and ensuring the comfort of the elevator car.

[0005] Most existing elevator ventilation systems are equipped with a single exhaust fan, which forces fresh air into the elevator car from the shaft while expelling stale air to achieve ventilation. However, if the fan is damaged or there are many people inside, the ventilation efficiency will be greatly reduced, leading to insufficient oxygen and causing discomfort to passengers. Therefore, existing elevator ventilation systems need to be optimized and improved. Summary of the Invention

[0006] The technical problem to be solved by this utility model is to overcome the defects of the prior art and provide an automatic ventilation and air exchange device for elevators, which achieves the effect of automatic air intake and adjustment under the premise of existing fan ventilation.

[0007] To solve the above-mentioned technical problems, the technical solution of this utility model is: an automatic ventilation and air exchange device for elevators, comprising:

[0008] The car has a top plate installed at the top, an air outlet plate is provided at one end of the inner side of the top plate, and an air inlet grille is provided in the middle of the inner side of the top plate.

[0009] An auxiliary ventilation component is provided on one side of the air inlet grille frame, and the auxiliary ventilation component includes:

[0010] An air inlet box is fixedly installed on one side of the top of the top plate. A Z-shaped filter plate is provided on the inner side of the air inlet box, and an air concentrator is installed on one side of the air inlet box.

[0011] A ventilation diverting component is provided at one end of the air inlet grille frame, and the ventilation diverting component includes:

[0012] A ventilation box is fixedly installed at the center of the top of the top plate, and a fitting plug is provided on the inner side of the ventilation box.

[0013] Furthermore, a fan connected to the air outlet plate is fixedly installed at one end of the top of the top plate, and the fan is connected to the air exchange box through a pipe.

[0014] Furthermore, an external air duct is provided on the inner side of the top wall of the air exchange box, and an internal air duct is provided inside the side wall of the air exchange box. An internal circulation pipe is connected between the air inlet grille and the internal air duct.

[0015] Furthermore, the inner ends of the ventilation box are rotatably connected to a rotating shaft, and the fitting plug is fixedly installed on the outer side of the rotating shaft. The fitting plug is adapted to fit the inner side of the external air duct and the internal air duct.

[0016] Furthermore, a filter screen is fixedly installed on one end of the inner side of the ventilation box.

[0017] Furthermore, the inner side of the air inlet box is provided with a plug-in mounting groove adapted to the Z-shaped filter plate, and plug-in positioning blocks are fixedly connected to both ends of the Z-shaped filter plate.

[0018] Furthermore, a ventilation duct is connected between the air inlet box and the top side of the air inlet grille frame.

[0019] Furthermore, there are two air-gathering ducts, which are symmetrically arranged on one side of the air inlet box, and a filter baffle is provided on the inner side of the air-gathering duct.

[0020] By adopting the above technical solution, this utility model has the following beneficial effects:

[0021] When adjusting the ventilation inside the elevator car, it is difficult to achieve rapid ventilation by simply connecting the ventilation through the fan. During the elevator's ascent and descent, the air-gathering duct installed on the outside draws air into the interior of the car as it moves, driving the airflow inside the car. This increases the ventilation effect of the existing single ventilation method and improves the comfort of elevator use.

[0022] A rotatable fitting plug is installed on the inside of the air exchange box for replacing and adjusting the external and internal air ducts, which facilitates the switching of internal air circulation in the car and external air circulation in the car and ventilation shaft to adapt to environmental requirements.

[0034] An auxiliary ventilation component 8 is provided on one side of the air inlet grille frame 5. The auxiliary ventilation component 8 is used to automatically introduce air into the air shaft according to the movement of the car 1 while the fan 4 is ventilating.

[0035] The auxiliary ventilation assembly 8 includes an air inlet box 801 fixedly installed on one side of the top of the top plate 2. The air inlet box 801 is used as a transfer point when the external air shaft is intake. A Z-shaped filter plate 803 is provided on the inner side of the air inlet box 801. The Z-shaped filter plate 803 is a combination of multiple Z-shaped filter plates, which can increase the contact area with the outside air during filtration and improve the filtration effect. An air concentrator duct 806 is installed on one side of the air inlet box 801.

[0036] like Figure 3 As shown, the inner side of the air inlet box 801 is provided with a plug-in mounting groove 802 that is compatible with the Z-shaped filter plate 803. Both ends of the Z-shaped filter plate 803 are fixedly connected with plug-in positioning blocks 804. The Z-shaped filter plate 803 is inserted into the plug-in mounting groove 802 for further installation. The compatible positioning installation improves the sealing performance. The outer side is fixed by screws screwed into the plug-in positioning blocks 804.

[0037] like Figure 3 As shown, a ventilation pipe 805 is connected between the air inlet box 801 and the top side of the air inlet grille 5. The ventilation pipe 805 is used to transmit the air filtered by the external air shaft to the air inlet grille 5 and then diffuse it evenly into the interior of the car 1.

[0038] like Figure 3 As shown, there are two air-gathering ducts 806, which are symmetrically arranged on one side of the air inlet box 801. The two air-gathering ducts 806 are symmetrically arranged with one opening facing upward and the other facing downward. When the car 1 moves, they introduce air from the outer air shaft into the air inlet box 801. A filter baffle 807 is provided on the inner side of the air-gathering duct 806. After being filtered by the filter baffle 807, the air introduced into the air inlet box 801 is transmitted to the air inlet grille 5 through the ventilation duct 805, automatically injecting fresh air into the car 1.

[0039] A ventilation reversing component 7 is provided at one end of the air inlet grille frame 5. The ventilation reversing component 7 is used to adjust the internal or external circulation of the car 1.

[0040] The ventilation reversing assembly 7 includes an air exchange box 701 fixedly installed at the top center of the top plate 2. The air exchange box 701 is used for the transfer of air drawn out by the fan 4 inside the car 1. A fitting plug 705 is provided on the inner side of the air exchange box 701.

[0041] like Figure 1As shown, a fan 4 connected to the air outlet plate 3 is fixedly installed at one end of the top plate 2. The fan 4 is connected to the air exchange box 701 through a pipe. The fan 4 is connected to the inside of the car 1 through the air outlet plate 3. It is used to extract the turbid air inside the car 1 and transmit it to the inside of the air exchange box 701 through the pipe.

[0042] like Figure 4 As shown, an external air duct 702 is provided on the inner side of the top wall of the air exchange box 701. The external air duct 702 is used to discharge the turbid air transferred in the air exchange box 701 into the air shaft. An internal air duct 703 is provided inside the side wall of the air exchange box 701. An internal circulation pipe 6 is connected between the air inlet grille frame 5 and the internal air duct 703. The internal air duct 703 is used to recirculate the air filtered by the air exchange box 701 back into the car 1.

[0043] like Figure 4 As shown, the inner ends of the ventilation box 701 are rotatably connected to the rotating shaft 704. The fitting plug 705 is fixedly installed on the outer side of the rotating shaft 704. The fitting plug 705 is adapted to fit the inner side of the external air duct 702 and the internal air duct 703. Under the rotation adjustment of the rotating shaft 704, the fitting plug 705 can fit to fit the inner wall of the external air duct 702 and the internal air duct 703 to control the exhaust direction of the air inside the car 1.

[0044] like Figure 4 As shown, a filter screen 706 is fixedly installed on one end of the inner side of the air exchange box 701. The filter screen 706 is used to filter the air drawn from inside the car 1.

[0045] The working principle of this utility model is as follows: The car 1 serves as the carrier of the elevator for passengers or goods. During use, the operation of the fan 4 drives the air outlet plate 3 to draw air from inside the car 1, which is then transferred to the ventilation box 701 through the pipe. The position of the fitting plug 705 is adjusted according to the environmental needs. When used for external ventilation, the fitting plug 705 blocks the internal air duct 703; when used for internal circulation ventilation, the fitting plug 705 blocks the external air duct 702. The rotation of the fitting plug 705 is controlled by a motor installed on one side of the rotating shaft 704. Because the car 1 itself is equipped with a weight sensor, the number of people is determined based on the internal weight, and the internal or external air circulation is controlled according to the needs. During the movement of the car 1, air from the external ventilation shaft is introduced into the air inlet box 801. After being filtered by the filter baffle 807, it is transmitted to the air inlet grille 5 through the ventilation pipe 805, automatically injecting fresh air into the car 1 and improving the comfort of the passengers.
