Description

Technical Field

[0001] This utility model relates to the field of elevator technology, and in particular to an elevator with an energy-saving cooling structure. Background Technology

[0002] An elevator is a means of transportation used for vertical transportation within a building. It is electrically powered and runs along rigid guide rails. It is mainly used to transport people and goods. The elevator car can run between at least two rigid guide rails that are perpendicular to the horizontal plane or have an inclination angle of less than 15°, providing a fast and efficient way to move between floors.

[0003] Some traditional elevators do not have a stable cooling function. Especially in summer, they can only rely on the airflow entering through the ventilation vents during elevator upgrades to cool down. This cooling method is too inefficient, and passengers will still be very hot, resulting in low overall user comfort. Utility Model Content

[0018] This utility model has the following beneficial effects:

[0019] This elevator, equipped with an energy-saving cooling structure, uses a fan to drive airflow. The airflow passes through an outlet duct, heat exchange duct, and connecting pipe into the air blower frame, and is then blown out from the outlet. As the airflow passes through the heat exchange duct, it exchanges heat with the cooling water in the liquid storage chamber, turning it into cold air. This cold air is then blown into the elevator car to cool it down, ensuring comfort during the summer. The structure, including a protective box, filter frame, filter screen, and activated carbon filling layer, filters and purifies the airflow drawn into the car, removing dust and odors to avoid affecting passengers. A semiconductor cooler periodically cools the cooling water in the liquid storage chamber, ensuring stable heat exchange and cooling of the airflow passing through the heat exchange duct.

[0028] Reference Figure 1-4This utility model provides an embodiment of an elevator with an energy-saving cooling structure, comprising an elevator car 1, a blower 2 fixedly connected near the top of the elevator car 1, an air outlet 3 provided on the blower 2, a fixed box 5 located on the top of the elevator car 1 near one side, a liquid storage chamber 6 provided inside the fixed box 5, and a heat exchange tube 7 provided inside the liquid storage chamber 6. The heat exchange tube 7 is made of copper and is S-shaped, allowing for easy connection with the liquid storage chamber. Cooling water in the liquid chamber 6 exchanges heat. The S-shaped heat exchange tube 7 ensures that the airflow passing through the tube 7 can fully exchange heat with the liquid chamber 6, turning it into low-temperature cold air. One end of the heat exchange tube 7 is connected to a connecting pipe 8 that communicates with the blower frame 2. A fan 9 is installed on one side of the top of the elevator car 1. An air outlet pipe 10 is installed at the outlet of the fan 9, communicating with the heat exchange tube 7. When the fan 9 operates, it drives the airflow, which passes through the air outlet pipe 10 and enters the heat exchange tube 7. The airflow enters the blower frame 2 through the connecting pipe 8 and is then blown into the car through the air outlet 3. When the airflow passes through the heat exchange pipe 7, it can exchange heat with the cooling water in the liquid storage chamber 6 and become low-temperature air. The low-temperature air enters the car and can cool the car. The air inlet of the fan 9 is provided with an air inlet pipe 11, and a protective box 12 is provided on the air inlet pipe 11. An air inlet slot 13 is provided on one side of the outer surface of the protective box 12, and two filter frames 15 are provided inside the protective box 12. The two filter frames 15 are respectively provided with a filter screen 18 and an activated carbon filling layer 19. The filter screen 18 can filter the airflow and filter out dust, while the activated carbon filling layer 19 can purify the airflow and absorb odors. A semiconductor cooler 22 is provided on the fixed box 5. The cold end of the semiconductor cooler 22 is located in the liquid storage chamber 6, and the hot end is located on the outside of the fixed box 5. In this way, the cooling water in the liquid storage chamber 6 can be cooled during operation, and the hot end can dissipate heat naturally on the outside.

[0029] The blower frame 2 is equipped with a controller 4. The blower 9, the semiconductor cooler 22 and the controller 4 are electrically connected. The controller 4 is equipped with a control switch and an indicator light, which can facilitate the opening and closing control of the structure.

[0030] A grille plate 14 is installed inside the air inlet slot 13. The air inlet slot 13 is the air inlet position on the protective box 12. The grille plate 14 can provide initial protection for the air inlet position to prevent some insects from entering the structure.

[0031] Both filter frames 15 are fixedly connected to positioning sliders 16, and the inner wall of the protective box 12 is provided with positioning grooves 17. The positioning sliders 16 and positioning grooves 17 are nested and slidingly fitted, and the cross-sections of the positioning sliders 16 and positioning grooves 17 are both dovetail-shaped. This structure allows the filter frame 15 to be stably installed in the protective box 12, and it can also be easily disassembled, making it convenient to clean or replace the filter frame 15.

[0032] The top and one side of the outer surface of the fixed box 5 are respectively provided with a liquid inlet connector 20 and a liquid outlet connector 21. A liquid level gauge 23 is provided on one side of the outer surface of the fixed box 5. The liquid inlet connector 20 and the liquid outlet connector 21 can facilitate the replenishment and drainage of liquid in the fixed box 5. The liquid level gauge 23 can be used to observe the liquid level in the fixed box 5.

[0033] A sealing door 24 is rotatably connected to the protective box 12. The sealing door 24 is designed to be easily opened, allowing for the disassembly and assembly of the filter frame 15.

[0034] Working principle: When using an elevator with an energy-saving cooling structure, the fan 9 is started, and the fan 9 drives the airflow. The airflow enters the heat exchange tube 7 through the air outlet 10, then enters the air blower 2 through the connecting pipe 8, and is then blown into the car from the air outlet 3. When the airflow passes through the heat exchange tube 7, it can exchange heat with the cooling water in the liquid storage chamber 6 and become low-temperature air. The low-temperature air enters the car and can cool the car. In summer, this can reduce the car temperature, ensure smooth airflow, and enhance the comfort of the elevator car 1.

[0035] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
