[0002] An elevator car is an enclosed transportation unit consisting of a car frame and a car body. The car frame, as the load-bearing main body, is composed of columns, bottom beams, and top beams. The car body includes walls and a roof made of fire-resistant and smoke-proof materials, and is equipped with a ventilation and lighting system and emergency devices. According to public building codes, the net height inside a passenger elevator car must be no less than 2.3 meters, and temperature control measures must be in place. Currently, conventional elevator cars have ventilation equipment for air circulation inside the car. This conventional ventilation equipment is mostly installed at the top of the elevator car. In this case, ventilation is directly applied from the top, and the airflow direction cannot be adaptively adjusted according to actual application conditions, resulting in poor overall ventilation. Based on the above, this utility model proposes an elevator car with better ventilation, which can effectively solve the above problems. Utility Model Content

Detailed Implementation

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Example: like Figures 1-7 As shown, this utility model embodiment provides an elevator car with good ventilation, including a car body 1. The interior of the car body 1 has a load-bearing space 11. A ventilation unit 2 is installed in the load-bearing space 11 and mounted on the top wall of the car body 1. The ventilation unit 2 includes a ventilation fan 21 fixed to the top of the car body 1. The output end of the ventilation fan 21 has an air supply pipe 22. The ventilation unit 2 also includes an installation plate 23 installed on the top wall of the car body 1. A diversion hood 24 connected to the air supply pipe 22 is embedded in the installation plate 23. The bottom of the diversion hood 24 has a vertical ventilation slot 240, and both sides of the diversion hood 24 are provided with horizontal ventilation slots 241. The vertical ventilation slot 240 is provided with a vertical air guide plate 242, and the horizontal ventilation slot 241 is provided with a horizontal air guide plate 243. The horizontal air guide plate 243 and the vertical air guide plate 242 are connected and assembled together by a transmission unit 3.

[0018] Because the elevator car with good ventilation of this utility model has the above structure, through the setting of ventilation unit 2, the vertical air guide plate 242 and horizontal air guide plate 243 can be driven by the transmission unit 3 to adjust the air outlet position, so as to rotate the air outlet direction for different application scenarios and better realize the riding experience of the people in the car body 1.

[0019] Furthermore, in another embodiment, a rotating rod 244 is connected to the horizontal air guide plates 243 in the plurality of horizontal ventilation slots 241, so that rotating a single rotating rod 244 can achieve the rotation of the plurality of horizontal air guide plates 243. One end of the vertical air guide plate 242 extends into the movable cavity 245 and forms a rotating part 246. A gear 247 is fixed on the surface of the rotating part 246. The surfaces of multiple gears 247 mesh with a toothed plate 248. The toothed plate 248 is slidably assembled with the movable cavity 245. The toothed plate 248 is slidably disposed inside the movable cavity 245, so that the toothed plate 248 can only slide along the length direction of the movable cavity 245 without shaking.

[0020] Because the elevator car of this invention has the above structure with good ventilation, after the single toothed plate 248 slides along the length of the movable cavity 245, the toothed plate 248 can synchronously mesh with the corresponding multiple gears 247. Driven by this meshing action, the gears 247 will drive the vertical air guide plate 242 to move within the corresponding vertical ventilation slot 240 via the rotating part 246. Figure 5 As shown, in this state, the vertical air guide plate 242 is perpendicular to the ground. Therefore, the air inside it is vertically discharged to the outside through the vertical ventilation slot 240 for ventilation. When the vertical air guide plate 242 is driven by the toothed plate 248, it can rotate 90 degrees within the vertical ventilation slot 240, thereby blocking the vertical ventilation slot 240 and closing the ventilation path in the vertical direction.

[0021] Furthermore, in another embodiment, the transmission unit 3 includes a transmission cavity 31 opened in the diverter shroud 24. One end of the toothed plate 248 extends into the transmission cavity 31 and is engaged with a transmission gear 32. An adjusting rod 33 is fixed on the surface of the transmission gear 32. One end of the adjusting rod 33 passes through the outside of the diverter shroud 24 and is connected to a rotating handle. Rotating the rotating handle can cause the adjusting rod 33 to rotate. The rotating adjusting rod 33 can drive the transmission gear 32 on it to rotate. The transmission gear 32 will then mesh with the adjacent toothed plate 248. The toothed plate 248 driven by the meshing action slides and drives multiple gears 247 to rotate, ultimately realizing the control of multiple vertical guide plates 242. Furthermore, one end of the rotating rod 244 extends into the transmission cavity 31 and is fixed coaxially with the transmission gear 32; Furthermore, both sides of the diversion hood 24 are connected to air guide pipes 249, and the horizontal ventilation slot 241 is connected to the corresponding air guide pipe 249. Since the elevator car with good ventilation of this utility model has the above structure, when the above adjusting rod 33 is rotated, the rotating adjusting rod 33 will drive the transmission gear 32 to rotate. While the rotating transmission gear 32 is meshing with the tooth plate 248, it can also synchronously drive the rotating rod 244 to rotate. In this way, the rotating rod 244 can drive the horizontal air guide plate 243 on it to rotate. like Figure 5 As shown, in the initial state, the vertical air guide plate 242 does not block the interior of the vertical ventilation slot 240, while the horizontal air guide plate 243 blocks the horizontal ventilation slot 241. Thus, when the adjusting rod 33 is rotated, the vertical air guide plate 242 gradually blocks the vertical ventilation slot 240, while the horizontal air guide plate 243 gradually releases its blockage of the horizontal ventilation slot 241. When the vertical air guide plate 242 completely blocks the vertical ventilation slot 240, the horizontal air guide plate 243 completely releases its blockage of the horizontal ventilation slot 241, thereby allowing the vertical ventilation slot to open. The ventilation direction is changed from directional to horizontal, which allows for adjustment of the ventilation direction according to the actual application, or manual adjustment of the air volume in a single direction to improve the overall ventilation effect. For example, when the air volume of the vertical ventilation slot 240 increases, the air volume of the adjacent horizontal ventilation slot 241 will decrease, and vice versa. Alternatively, the vertical ventilation slot 240 or the horizontal ventilation slot 241 can be closed arbitrarily to achieve ventilation in a single location.

[0022] The mounting plate 23 has an assembly groove 230 on its surface, and ventilation grooves 231 are provided on both sides of the assembly groove 230. The diversion hood 24 is fixed in the assembly groove 230, so that the air guide duct 249 is located in the ventilation groove 231. When horizontal ventilation is performed, the air guide duct 249 can transmit the air volume towards the side wall of the elevator, which can further reduce the direct downward blowing on the heads of people standing below, and make the air volume more gentle in colder seasons, avoiding irritation to the head and affecting comfort. A decorative panel 232 is fitted inside the assembly slot 230 to cover the air duct 249.

[0023] Since the elevator car with good ventilation of this utility model has the above structure, in practical application, the diversion hood 24 is embedded in the assembly groove 230 and fixed with bolts so that the air guide pipes 249 on both sides are located inside the ventilation groove 231. Then, the external decorative panel 232 is fastened to the surface of the air guide pipe 249 to cover it.
