Description

Technical Field

[0001] This utility model relates to the field of elevator technology, and in particular to a passenger elevator ceiling assembly. Background Technology

[0002] Passenger elevator ceiling components are a combination of functional and decorative parts installed on the top of the elevator car. They are usually supported by a frame made of metal profiles (such as aluminum alloy and steel), with ceiling panels made of materials such as stainless steel and acrylic as the main body, and integrated with lighting fixtures such as LED downlights and strip lights. Their core function is to beautify the interior environment of the car, provide uniform and soft lighting to ensure the visual needs of passengers, and at the same time hide mechanical parts and wires on the top of the car, making the interior cleaner.

[0003] Currently, most passenger elevator ceilings use LED lights as their core component. Through simple lighting design and a neat layout, they make the elevator car interior look more aesthetically pleasing and tidy, improving the basic elevator environment to some extent. However, the function of these ceilings is relatively limited, mostly only meeting lighting and basic decorative needs. Furthermore, since elevator cars are relatively enclosed spaces, it's inevitable that some people will smoke inside during passenger flow. Common ceilings typically rely on simple ventilation openings for air circulation, resulting in low ventilation efficiency and difficulty in quickly dissipating odors such as smoke. Especially in summer, the enclosed car, ventilated only by simple openings, cannot effectively reduce the stuffiness and refresh the air, causing discomfort for passengers and significantly impacting the overall elevator experience.

[0025] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0026] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0027] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0028] Example 1:

[0029] Reference Figures 1-5This is the first embodiment of the present utility model. This embodiment provides a passenger elevator ceiling assembly, including a base frame 2 at the bottom of a top plate 1, multiple decorative panels 3 arranged in an array inside the base frame 2, light panels 4 installed on both sides inside the base frame 2, a positioning shell 5 installed inside the top plate 1, a ventilation assembly 6 with purification function installed inside the positioning shell 5, and mounting brackets 7 on both sides of the base frame 2.

[0030] The top plate 1 facilitates installation with elevator bridges and provides support for the base frame 2. The base frame 2 is used to fix the decorative panel 3 and the light panel 4. The light panel 4 is powered by an external power supply via a cable. The positioning shell 5 is installed between the top plate 1 and the base frame 2, which facilitates the fixed installation of the ventilation component 6. The ventilation component 6 is used to actively dissipate heat inside the elevator car, improving the comfort of passengers riding the elevator.

[0031] The ventilation assembly 6 includes a fan 601 and a guide shell 602. The fan 601 is installed inside the positioning shell 5, and the guide shell 602 is fixed to both sides of the positioning shell 5.

[0032] The fan 601 is fixed inside the positioning housing 5 and is powered by an external cable. It is electrically connected to a PLC control or a gas sensor to control the fan 601 to rotate actively or passively, thereby directly adsorbing the air at the bottom of the base frame 2 inside the bridge chamber under negative pressure.

[0033] Example 2:

[0034] Reference Figures 3-5 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0035] Specifically, the ventilation assembly 6 also includes an exhaust housing 603 fixed to one side of the guide housing 602, and one side of the guide housing 602 is L-shaped.

[0036] By vertically oriented exhaust housing 603 and connecting it to guide housing 602, the purified airflow can be precisely guided. Furthermore, since one side of guide housing 602 is L-shaped, two-thirds of the gas discharged from fan 601 can be guided into guide housing 602 and exhaust housing 603 for recycling.

[0037] Specifically, there are two flow guide shells 602, which are symmetrically and obliquely arranged.

[0038] The guide shells 602 are symmetrically arranged and angled, which can better guide the airflow and achieve the effect of recycling. There is also a certain exhaust space between the tops of the two symmetrically arranged guide shells 602, which is used to discharge a small portion of the airflow each time the air is exhausted, to prevent the airflow from going into a dead loop.

[0039] Specifically, the ventilation assembly 6 also includes guide blocks 604 fixed on both sides of the base frame 2, and the guide blocks 604 are tapered.

[0040] The guide block 604 is cone-shaped to facilitate the air-breaking and guiding effect, so that it can be evenly discharged from both sides of the base frame 2.

[0041] Specifically, the flow guide blocks 604 are arrayed and fixed on both sides of the base frame 2, and the top is flush with the exhaust shell 603.

[0042] By fixing the guide block 604 to both sides of the base frame 2, and having its top flush with the exhaust position of the exhaust shell 603, the airflow discharged from the exhaust shell 603 can be prevented from overflowing from other sides, causing most of the airflow to be lost and unable to be discharged from the position of the guide block 604.

[0043] Specifically, one side of the guide block 604 is fixedly connected to the mounting bracket 7, and the top of the mounting bracket 7 is fixed to the top plate 1 by screws.

[0044] The guide block 604 is fixed to the mounting bracket 7 on one side, and then fixed to the top plate 1, so as to facilitate the fixed installation of the base frame 2.

[0045] Example 3:

[0046] Reference Figures 3-5 This is the third embodiment of the present invention, which is based on the first two embodiments.

[0047] Specifically, a reinforcing rib 605 is fixedly connected to the top of the exhaust casing 603, and one side of the reinforcing rib 605 is fixed to the mounting bracket 7.

[0048] By fixing the reinforcing rib 605 between the exhaust shell 603 and the mounting bracket 7, the connection strength between the two can be improved, ensuring stability during long-term use.

[0049] Specifically, a filter plate 8 is inserted into the bottom of the inner cavity of the positioning shell 5, and one side of the filter plate 8 is fixed to the positioning shell 5 by screws.

[0050] The filter plate 8 is inserted into the positioning housing 5 and fixed by screws for easy disassembly and maintenance. The filter plate 8 is used to prevent dust from entering the air inlet at the bottom of the positioning housing 5, reducing the direct contact between dust and the fan 601 and causing blockage.

[0051] Specifically, a partition 9 is fixedly connected to the inner cavity of the positioning shell 5, and an activated carbon plate 10 for purifying gas is inserted into the inside of the positioning shell 5. One side of the activated carbon plate 10 is fixed to the positioning shell 5 by screws.

[0052] The activated carbon plate 10 is fixed inside the positioning shell 5 by the partition 9, which facilitates the insertion and fixing of the activated carbon plate 10. The activated carbon plate 10 is used to filter the airflow drawn into the positioning shell 5 under negative pressure and then recycle it.

[0053] Specifically, an exhaust port 11 is provided on the top of one side of the inner cavity of the positioning shell 5, and an escape door panel 12 is hinged to one side of the top of the top plate 1.

[0054] The exhaust vent 11 is located on the side of the positioning shell 5, which can reduce the possibility of dust falling into the positioning shell 5. The escape door panel 12 is a specific emergency measure inside the elevator, used for passenger escape.

[0055] In use, the elevator car is first fixed to the bracket inside the elevator shaft by multiple threaded heads on the top of the top plate 1. During use, if passengers need to remove odors and ventilate the inside of the car, the fan 601 can be controlled by an external PLC through an electrical connection. At this time, the airflow inside the elevator car will pass through the positioning shell 5, filter dust through the filter plate 8, and then be discharged to the top of the positioning shell 5 through the activated carbon plate 10. At this time, part of the airflow will be blocked by the two guide shells 602 and flow into the exhaust shell 603. The diameter is distributed to both sides of the base frame 2 through the guide block 604 and discharged into the elevator car, thereby achieving the effect of ventilation.

[0056] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
