Description

Technical Field

[0001] This utility model relates to the field of elevators, specifically to an elevator car air conditioning vent connection structure and an elevator. Background Technology

[0002] Elevator car ceilings are typically made of metal sheets. If an elevator car air conditioner is installed, condensation easily forms on the metal surface due to pre-cooling, especially at the air vents on the car or ceiling where the cold air is blown out. Frequent and prolonged condensation can affect the corrosion resistance of the ceiling or car. When a significant amount of condensation accumulates, it will drip under gravity. If this drips onto the car floor, it poses a risk of slipping for passengers or causes a poor riding experience. Therefore, reducing or even preventing condensation in elevators with air conditioning is essential.

[0003] There is already existing technology that installs a condensate collection and evaporation structure on the top of the elevator car. Although this method can avoid the above-mentioned problems caused by condensate, such structures are relatively complex and will increase production costs. Utility Model Content

[0004] The purpose of this invention is to overcome the problem of high production costs in solving the condensation problem of elevator air conditioning vents in existing technologies, and to provide an elevator car air conditioning vent connection structure and an elevator. This connection structure is simple, easy to implement, and economical.

[0005] To achieve the above objectives, the first aspect of this utility model provides an elevator car air conditioning vent connection structure, wherein the connection structure includes a metal car ceiling, a cold air outlet is provided on the car ceiling, a first air outlet pipe is inserted into the cold air outlet, an air conditioner is provided above the car ceiling, and the air outlet of the air conditioner is connected to a second air outlet pipe. The upper surface of the car ceiling is provided with a wooden or plastic heat insulation pad, and a second through hole is provided on the heat insulation pad. The inlet end of the first air outlet pipe passes through the second through hole and is connected to the second air outlet pipe. The outlet end of the first air outlet duct is connected to a plastic air outlet louver, which is located below the car ceiling. A first insulation cotton is provided between the air outlet louver and the car ceiling, and the first insulation cotton surrounds the corresponding first air outlet duct.

[0006] By adopting the above technical solution, a ring of insulation cotton is set around the first air outlet duct on the air outlet louvers and the car ceiling, and an insulation pad is set on the upper surface of the car ceiling. This allows the car ceiling around the cold air outlet to play a good role in heat preservation. Moreover, the air outlet louvers at the final air outlet are made of plastic, which effectively avoids the formation of condensation at the cold air outlet of the metal car ceiling. This structure is simple, does not require additional modifications to the existing elevator structure, and has an outstanding anti-condensation effect, which is conducive to its promotion.

[0007] Preferably, the orthographic projection of the thermal insulation pad onto the preset plane is larger than the orthographic projection of the air outlet louvers onto the preset plane, and the preset plane is parallel to the car ceiling. This structure, by increasing the area of ​​the thermal insulation pad, helps to further enhance the heat insulation effect and improve the anti-condensation effect.

[0008] Preferably, the closest distance between the orthographic projection of the edge of the thermal insulation pad on the preset plane and the orthographic projection of the edge of the air outlet louver on the preset plane is 10-30cm. With this structure, the thermal insulation pad essentially covers the area on the upper surface of the car ceiling where condensation may occur, further improving the anti-condensation effect.

[0009] Preferably, the thickness of the thermal insulation pad is 2-20mm. Selecting a thermal insulation pad of suitable thickness can reduce production costs while ensuring condensation prevention.

[0010] Preferably, the outer diameter of the first insulation cotton is 15-50mm larger than the diameter of the cold air outlet. This structure ensures that the first insulation cotton essentially covers the area on the lower surface of the car ceiling where condensation may occur, further improving the anti-condensation effect.

[0011] Preferably, a retaining plate is provided on the first air outlet duct above the thermal insulation pad, and the retaining plate abuts against the thermal insulation pad. This structure facilitates the installation and fixation of the first air outlet duct.

[0012] Preferably, the outlet end of the first air outlet pipe is inserted into the second air outlet pipe, and the insertion portion of the second air outlet pipe and the first air outlet pipe, as well as the first air outlet pipe above the clamping plate, are all wrapped with a second insulating cotton. With this structure, by wrapping the second insulating cotton around the joint of the first and second air outlet pipes, cold air can be effectively prevented from escaping, avoiding the formation of condensation.

[0013] Preferably, the height to which the second insulation cotton is wrapped around the second air outlet pipe is higher than the height to which the first air outlet pipe is inserted into the second air outlet pipe.

[0014] Preferably, the thickness of both the first and second insulation cotton is 1-10mm.

[0015] The second aspect of this utility model provides an elevator, wherein the elevator includes the connection structure described in the first aspect of this utility model.

[0016] This application provides excellent insulation for the car ceiling around the cold air outlet by installing heat insulation pads and insulation cotton on the upper and lower surfaces of the car ceiling, effectively preventing condensation from forming at the cold air outlet of the metal car ceiling. This structure is simple, requires no additional modifications to the existing elevator structure, and has outstanding anti-condensation effect, making it easy to promote.
