Description

Technical Field

[0001] This invention relates to the field of elevator technology, and more specifically to a landing display and elevator system that solves the chimney effect problem. Background Technology

[0002] High-rise buildings commonly experience the chimney effect. The chimney effect refers to the phenomenon where air flows upward and accumulates in the elevator shaft from the bottom, causing the air pressure inside the shaft to be greater than the air pressure outside the elevator hall. This results in the elevator hall doors being subjected to greater vertical air pressure, making them difficult to open or even unable to open normally. In addition, because the elevator hall doors cannot be completely sealed when closed, rising air will flow out from the gaps in the door panels, generating wind noise, which will affect the comfort of passengers waiting for the elevator.

[0003] Traditional solutions to the chimney effect include "blocking" and "unblocking." Blocking primarily involves adding wind deflectors or rubber strips between the landing door and the door frame, as illustrated in Chinese patent document (CN120964567A). However, due to significant differences in the positional dimensions between different elevator landing doors and door frames, and the high dimensional accuracy requirements of this method, its effectiveness is often unsatisfactory. The solution of "unblocking" to address the chimney effect essentially involves adding pressure relief vents to the enclosed shaft to reduce the air pressure difference between the inside and outside of the shaft. However, this solution is often rejected due to its impact on the building's aesthetics. Summary of the Invention

[0004] To address the aforementioned technical problems, this invention provides a landing display that solves the chimney effect problem. The display includes a display unit and a ventilation unit. The landing display is installed on the wall of the elevator lobby outside the elevator shaft. The display unit has a display panel. The ventilation unit is fixed to the rear of the display unit. A top through-hole and a back through-hole in the ventilation unit form an airflow path. The ventilation unit covers the pressure relief port of the elevator shaft, and the back through-hole communicates with the pressure relief port. An isolation net is installed at the top through-hole.

[0005] Preferably, the landing display is installed on the wall above the elevator landing door.

[0006] Preferably, the display panel is at a preset angle to the wall.

[0007] Preferably, an isolation net is installed at the through hole on the back.

[0008] The present invention also provides an elevator system, including an elevator shaft and a landing display; the landing display is the aforementioned landing display; the elevator shaft has a pressure relief port, which is disposed on the shaft wall above the elevator landing door; the landing display is installed in such a way that the back through hole communicates with the pressure relief port, and the pressure relief port is not visible.

Detailed Implementation

[0010] The following specific embodiments illustrate the implementation of the present invention. Those skilled in the art can fully understand other advantages and technical effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through different specific embodiments, and the details in this specification can also be applied based on different viewpoints, with various modifications or changes made without departing from the overall design concept of the invention. It should be noted that, unless otherwise specified, the following embodiments and features can be combined with each other. The following exemplary embodiments of the present invention can be implemented in many different forms and should not be construed as being limited to the specific embodiments set forth herein. It should be understood that these embodiments are provided to make the disclosure of the present invention thorough and complete, and to fully convey the technical solutions of these exemplary embodiments to those skilled in the art. Example 1

[0011] like Figure 1 and Figure 2 As shown, this embodiment provides a landing display 1 including a display unit 11 and a ventilation unit 12. The landing display 1 is installed on the wall of the waiting hall outside the elevator shaft. The display unit 11 has a display panel. The ventilation unit 12 is fixed to the rear side of the display unit. The top through hole and the back through hole of the ventilation unit 12 form an air circulation path. The ventilation unit 12 covers the pressure relief port 22 of the elevator shaft. The back through hole communicates with the pressure relief port 22. An isolation net is installed at the top through hole.

[0012] More specifically, the landing display is mounted on the wall above the elevator landing door 3. The display panel is at a preset angle to the wall. An isolation net is installed at the through-hole on the back.

[0013] In this embodiment, the isolation net on the landing display serves as both a pressure relief vent and is located in the blind spot of a person standing on the landing. This ensures both a reduction in the air pressure difference between the inside and outside of the shaft and that the pressure relief vent does not affect the building's aesthetics. Simultaneously, the isolation net on the landing display also prevents foreign objects from entering the shaft from the landing side. Example 2

[0014] The elevator system provided in this embodiment includes an elevator shaft and the landing display as described in claim 1. Figure 2 As shown, the elevator shaft has a pressure relief port 22, which is located on the shaft wall above the elevator landing door; the landing display is installed in a position such that the back through hole communicates with the pressure relief port 22, and the pressure relief port 22 is not visible.

[0015] like Figure 3 As shown, when the elevator car moves upwards away from the current floor, a localized low pressure is created within the hoistway at that floor. High-pressure air outside the hoistway enters the hoistway through the isolation nets on the top and back of the floor display 1, thereby reducing the pressure difference between the inside and outside of the hoistway and achieving pressure relief.

[0016] like Figure 4 As shown, when the elevator car descends and moves away from the current floor, a localized high pressure is created at that floor within the hoistway. The high-pressure air inside the hoistway enters the relatively low-pressure side of the floor outside the hoistway through the isolation nets on the top and back of the floor display 1, thereby reducing the pressure difference between the inside and outside of the hoistway and achieving pressure relief.

[0017] The present invention has been described in detail above through specific embodiments and examples, but these are not intended to limit the invention. Many modifications and improvements can be made by those skilled in the art without departing from the principles of the invention, and these should also be considered within the scope of protection of the present invention.
