[0030] Please refer to Figures 1 to 4 The present application provides a ventilation elevator car, comprising a car 1, a heat dissipation device 2 and a protective piece 3. Wherein, the car 1 comprises a car body 11 and a ventilation opening 12 opened on the car body 11. In the height direction, the ventilation opening 12 is opened at the bottom of the car body 11. The heat dissipation device 2 comprises a connecting piece 21 connected with the car body 11 and a heat dissipation fan 22 provided on the connecting piece 21. The air inlet of the heat dissipation fan 22 is connected with the outside of the car body 11, and the air outlet of the heat dissipation fan 22 is connected with the ventilation opening 12. The protective piece 3 is detachably connected with the car body 11 and can cover at least part of the ventilation opening 12. The protective piece 3 is provided with a plurality of through grooves 31, and the through grooves 31 communicate the ventilation opening 12 and the inside of the car body 11.

[0031] Understandably, the ventilation opening 12 is arranged at the bottom of the car body 11, and the heat dissipation fan 22 is arranged at the ventilation opening 12. When the heat dissipation fan 22 is started, the air outside the car body 11 is transported to the air outlet, and then transported to the ventilation opening 12 through the air outlet, and then transported to the inside of the car body 11 through the ventilation opening 12 and the through slot 31 on the protective piece 3 covering the ventilation opening 12, that is, the air is blown upward from the bottom of the car body 11, and the lower part of the car body 11 is heat dissipated. In the case of a large number of people, the lower part of the car body 11 can also maintain good heat dissipation effect, and the comfort of the passengers riding the elevator is improved.

[0032] Understandably, the bottom of the car body 11 is the position where the passengers stand, and if there is a large opening, it is easy to cause safety hazards. The protective piece 3 can cover the ventilation opening 12 to avoid the existence of a large opening at the bottom of the car body 11, so that the feet of the passengers do not get stuck, or the articles are not easy to fall from the opening, and the safety is improved. Secondly, the detachable connection of the protective piece 3, when the heat dissipation fan 22 needs to be repaired or the ventilation outlet needs to be cleaned in the later period, only the protective piece 3 needs to be removed to operate.

[0033] In this embodiment, the protective piece 3 completely covers the ventilation opening 12, and there is no gap between the two, which is safer. Preferably, the size of the protective piece 3 is the same as the size of the ventilation opening 12, and the protective piece 3 can be completely embedded into the ventilation opening 12, and the upper surface of the protective piece 3 is flush with the bottom surface of the car body 11, so that there is no obvious protrusion when the passengers stand, and the comfort is higher.

[0034] Of course, it is not limited to this, in other embodiments, the protective piece 3 can also cover only part of the ventilation opening 12, that is, there is a certain gap between the two, as long as the gap does not cause the feet of the passengers to get stuck.

[0035] In an embodiment, the car body 11 is provided with a bearing piece 4 corresponding to the position of the ventilation opening 12, the bearing piece 4 is located below the protective piece 3, and the protective piece 3 and the bearing piece 4 are detachably connected. The bearing piece 4 supports the protective piece 3 at the lower part of the protective piece 3, and takes the bearing piece 4 as the bearing key to bear the people standing in the car 1 together with the protective piece 3, so that in the case of a large number of people, it can still be stably supported and is not easy to fall.

[0036] Exemplarily, the bearing piece 4 is provided in a plurality, and the plurality of bearing pieces 4 are distributed along the length direction of the ventilation opening 12. The two ends of the bearing piece 4 are respectively connected with the ventilation opening 12 or the car body 11, and after the plurality of bearing pieces 4 are distributed along the length direction of the ventilation opening 12, the bearing piece 4 provides support in multiple directions for the protective piece 3, and the support effect is good. Even if the ventilation opening 12 is divided into a plurality of small openings by the plurality of bearing pieces 4, the ventilation effect will not be affected.

[0037] Exemplarily, the load-bearing member 4 is in a strip structure, and two ends of the load-bearing member 4 are respectively welded and fixed to the inner walls of the opposite sides of the ventilation opening 12. Of course, the present application is not limited thereto, and in other embodiments, the two ends of the load-bearing member 4 can also be fixed to the inner walls of the ventilation opening 12 or the bottom of the car body 11 by screwing or other means.

[0038] In an embodiment, the protection member 3 is detachably connected to the load-bearing member 4 by the locking member 5. The protection member 3 is provided with a first screw hole 51, and the load-bearing member 4 is provided with a second screw hole 52. The first screw hole 51 is screw-connected with the locking member 5, and the second screw hole 52 is screw-connected with the locking member 5. After the locking member 5 is screw-connected with the first screw hole 51 and the second screw hole 52 respectively, the protection member 3 can be firmly installed on the load-bearing member 4, and the screwing mode is simple in structure, firm in positioning, convenient in disassembly in later period, and convenient in maintenance.

[0039] Exemplarily, the locking member 5 is a screw or a bolt. The locking member 5, the first screw hole 51, and the second screw hole 52 are all provided in multiple numbers and are distributed at different positions of the protection member 3, so as to ensure the firm connection between the protection member 3 and the load-bearing member 4.

[0040] In an embodiment, the car body 11 is provided with a wind frame 6. The wind frame 6 is provided with a first air guide opening 61 and a second air guide opening 62. The first air guide opening 61 is connected to the inside of the car body 11, and the second air guide opening 62 is connected to the outside of the car body 11.

[0041] It can be understood that during the upward and downward movement of the car 1, the air outside the car body 11 can be guided into the wind frame 6 through the second air guide opening 62 and then guided into the inside of the car body 11 through the first air guide opening 61. The air blown out of the wind frame 6 and the heat dissipation fan 22 cooperate to dissipate heat in the inside of the car body 11, further improving the heat dissipation effect and the riding comfort. Moreover, the wind frame 6 utilizes the pressure change around the car 1 during the descending of the elevator to naturally guide air, without the need of setting a power source to drive, thereby saving energy consumption.

[0042] Exemplarily, the wind frame 6 is arranged at a middle or middle-upper position of the height of the car 1. In this way, the heat dissipation fan 22 is responsible for the heat dissipation of the lower part of the car 1, and the wind frame 6 is responsible for the heat dissipation of the middle or middle-upper part of the car 1, so that the ventilation and heat dissipation are more comprehensive and the effect is better.

[0043] Exemplarily, the wind frame 6 is fixed to the inner wall of the car body 11 and is in a U-shaped structure. The first air guide opening 61 is provided in multiple numbers, and the multiple first air guide openings 61 are arranged on the side of the wind frame 6 away from the inner wall of the car body 11 and are uniformly distributed along the length direction of the wind frame 6. The second air guide opening 62 is provided in multiple numbers, and the multiple second air guide openings 62 are arranged at the lower part of the wind frame 6 and are uniformly distributed along the length direction of the wind frame 6.

[0044] Specifically, the opening position of the U-shaped air frame corresponds to the door position of the compartment 11, that is, the air frame 6 is arranged at other positions except the door, and the ventilation area is maximized.

[0045] Further, the air frame 6 is provided with a wind guide pipe 7, one end of the wind guide pipe 7 is connected with the second air guide opening 62, and the other end extends to the bottom of the compartment 11. The end of the wind guide pipe 7 extending to the bottom of the compartment 11 penetrates out of the compartment 11 and is connected with the space at the bottom of the compartment 11.

[0046] Understandably, when the elevator rapidly descends, the downward pressure of the compartment 11 on the bottom of the elevator shaft can change the pressure at the bottom of the elevator shaft, and the air at the bottom enters the wind guide pipe 7 from the end of the wind guide pipe 7 extending out of the compartment 11, and then is blown into the interior of the car 1 through the second air guide opening 62, the air frame 6 and the first air guide opening 61.

[0047] In an embodiment, the bottom of the compartment 11 is provided with an expanding cover 8. The inner diameter of the expanding cover 8 gradually expands from the side close to the compartment 11 to the side away from the compartment 11. The end of the wind guide pipe 7 extending to the bottom of the compartment 11 is connected with the expanding cover 8.

[0048] Understandably, the setting of the expanding cover 8 plays a certain air guide role, so that more air can flow into the expanding cover 8 when the car 1 moves downward, and then be transported to the air frame 6 through the air guide pipe, the air inlet increases, and the heat dissipation effect is better.

[0049] Further, the inner wall of the compartment 11 is provided with a handrail 9, and the handrail 9 extends from the inner wall of the compartment 11 to the center of the compartment 11. The side of the handrail 9 close to the center of the compartment 11 protrudes from the side of the air frame 6 close to the center of the compartment 11.

[0050] Understandably, in this structure, when the personnel riding the elevator leans on the compartment 11, they will only lean on the handrail 9, but not on the air frame 6, avoiding the first air guide opening 61 on the air frame 6 being blocked.

[0051] Exemplarily, the handrail 9 is provided in two groups, which are arranged on the upper and lower sides of the air frame 6, respectively, to better separate the air frame 6 from the personnel. The handrail 9 is also provided in a U-shaped structure to ensure that the air frame 6 is completely isolated.

[0052] Further, the heat dissipation fan 22 is provided in a plurality of heat dissipation fans 22, which are arranged in an array on the connecting piece 21. The plurality of heat dissipation fans 22 work together to ventilate, and the heat dissipation effect is better.

[0053] Exemplarily, the connecting piece 21 is provided in a plate-shaped structure, and the shape and size of the connecting piece 21 are the same as those of the air vent, which can be directly embedded into the air vent.

[0054] Exemplarily, the connecting piece 21 is fixedly connected with the air vent by welding. Of course, detachable connection such as screwing can also be adopted.

[0055] Exemplarily, the heat dissipation fan 22 adopts an integrated fan with a driving motor. The driving motor is directly electrically connected with the power supply and control system of the elevator. When the elevator moves, the driving motor is controlled to start, and the heat dissipation fan 22 is driven to rotate. The control system and the specific control principle are prior art, and will not be described in detail.

[0056] Exemplarily, the protective piece 3 adopts a filter plate or a filter screen with a thickness, and the material can be selected according to actual needs.

[0057] The technical features of the above-described embodiments can be combined arbitrarily. In order to make the description simple, all possible combinations of the technical features in the above-described embodiments are not described, but as long as the combinations of the technical features do not exist, they should be considered as the scope of the present application.

[0058] The above-described embodiments only express several implementation manners of the present application, and the description is relatively specific and detailed, but it should not be understood as a limitation on the patent application scope. It should be pointed out that for ordinary skilled persons in the art, some modifications and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the patent protection scope of the present application should be subject to the appended claims.
