[0024] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0025] To better illustrate this utility model, a further detailed description of this utility model is provided below with reference to the accompanying drawings.

[0026] The terminology used in the embodiments of this application is for the purpose of describing particular embodiments only and is not intended to limit the embodiments of this application. The singular forms “a,” “the,” and “the” used in the embodiments of this application and the appended claims are also intended to include the plural forms unless the context clearly indicates otherwise. It should also be understood that the term “and / or” as used herein refers to and includes any or all possible combinations of one or more of the associated listed items.

[0027] Combination Figures 1 to 3 As shown, this utility model discloses an elevator air conditioner with fresh air intake, comprising:

[0028] The housing 100 has an air inlet panel 110 and an air outlet, the air outlet being connected to the elevator car;

[0029] A diffuser 200 is disposed outside the air inlet panel 110 and divides the air inlet panel 110 into a recirculating air inlet area 111 and a fresh air inlet area 112. The diffuser 200 has a recirculating air guide port 210. The recirculating air inlet area 111 is located within the coverage area of ​​the diffuser 200 and communicates with the recirculating air guide port 210. The fresh air inlet area 112 is located outside the coverage area of ​​the diffuser 200.

[0030] Compared with the prior art, this utility model divides the air inlet panel 110 into a circulating air inlet area 111 and a fresh air inlet area 112 by using a diversion hood 200. The fresh air inlet area 112 is located outside the coverage of the diversion hood 200. Even if the elevator door cannot be opened, outside air can still enter the interior of the housing 100 through the fresh air inlet area 112, and then enter the elevator car through the air outlet. This ensures that outside air can still be replenished when the elevator door cannot be opened, avoids danger to passengers due to lack of oxygen, and improves the passenger safety factor.

[0031] In one embodiment, see Figure 1 and Figure 3The area of ​​the recirculated air inlet area 111 is larger than the area of ​​the fresh air inlet area 112. The larger area of ​​the recirculated air inlet area 111 allows the air conditioning to rely primarily on the pre-conditioned air within the car for internal circulation, quickly adjusting the temperature and maintaining stability. In contrast, fresh air needs to be introduced from the external environment, resulting in a larger temperature difference and higher energy consumption. Reducing the fresh air inlet area can lower the overall operating power consumption; the fresh air inlet area only needs to meet basic ventilation requirements.

[0032] In one embodiment, see Figure 1 The fresh air inlet area 112 has multiple rows and / or columns of fresh air inlets. These multiple rows or columns form a distributed "grid" layout. By dividing the air inlet panel 110 into multiple small units, the geometric stability of the grid structure is used to disperse external forces, avoiding localized stress concentration and deformation caused by a single large opening. Preferably, the fresh air inlet has a strip-shaped perforation structure.

[0033] In one embodiment, see Figure 1 The circulating air inlet area 111 has multiple rows and / or columns of circulating air inlets. These multiple rows or columns form a distributed "grid" layout. By dividing the air inlet panel 110 into multiple small units, the geometric stability of the grid structure is utilized to disperse external forces, avoiding localized stress concentration and deformation caused by a single large opening. Preferably, the circulating air inlet has a strip-shaped perforation structure.

[0034] In one embodiment, see Figure 1 The cross-sectional area of ​​the flow divider 200 gradually increases from the circulating air guide port 210 to the air inlet panel 110, forming a gradually expanding flow channel. This structure allows the circulating air to gradually diffuse during the flow process, covering a larger area of ​​the circulating air entry region.

[0035] In one embodiment, see Figure 1 and Figure 2 An air supply assembly is provided inside the housing 100. This assembly is connected to an air supply volute 310 and a suction fan. The suction fan is located inside the air supply volute 310 and is used to discharge the airflow entering the air supply volute 310 into the elevator car. The air supply volute 310 is connected to the circulating air inlet area 111 and the fresh air inlet area 112. The suction fan draws the cooled circulating air and fresh air into the air supply volute 310 and discharges them into the elevator car through the flow channels within the air supply volute 310, allowing the cooling airflow to reach all corners of the car more efficiently.

[0036] In one embodiment, see Figure 3The elevator air conditioner with fresh air intake also includes an air purification device. This device is installed inside the housing 100 and positioned near the air inlet panel 110. It is used to purify the airflow entering the housing 100 via the recirculated air inlet area 111 and the fresh air inlet area 112. Because the air purification device is positioned near the air inlet panel 110, the recirculated air and fresh air come into contact with the air purification device after merging. The air purification device can simultaneously purify both airflows, improving the air quality in the elevator car.

[0037] Further, see Figure 3 The air purification device includes a filter 410, which overlaps with the recirculated air inlet area 111 and the fresh air inlet area 112 in the frontal visual projection direction. Since the filter 410 overlaps with both inlet areas in the frontal visual projection direction, the same filter 410 can be used to filter both recirculated and fresh air, eliminating the need for additional filters 410, reducing material usage and component quantity, and lowering equipment costs.

[0038] It should be noted that the filter 410 can cover the circulating air inlet area 111 and the fresh air inlet area 112, and may also have a certain overlap with the circulating air inlet area 111 and the fresh air inlet area 112.

[0039] The filter 410 includes a particulate filter and an activated carbon filter, which are arranged along the air inlet direction; wherein the particulate filter is used to filter particulate matter such as dust and PM2.5, and the activated carbon filter is used to adsorb odors.

[0040] Further, see Figure 3 The air purification device includes an ultraviolet lamp 420. The ultraviolet light emitted by the ultraviolet lamp 420 can kill bacteria, viruses, mold and other microorganisms carried in the circulating air and fresh air, reducing the risk of cross-infection in the enclosed space of the elevator.

[0041] Because the fresh air inlet area 112 is smaller than the circulating air inlet area 111, in this utility model, the ultraviolet lamp 420 is located in the circulating air inlet area 111 in the front visual projection direction. In this way, the ultraviolet lamp 420 does not need to occupy the space in the fresh air inlet area 112, thus avoiding obstructing the entry of fresh air.

[0042] Further, see Figure 3The air purification device also includes a negative ion generator 430, which can generate a large number of negative ions by ionizing the air with high voltage. The negative ions can adsorb particulate matter such as dust, pollen, and smoke in the air, making them charged and settling, thereby reducing suspended particulate matter in the air; at the same time, it can also neutralize positive ions in the air, reduce static electricity, improve air freshness, and make people feel more comfortable.

[0043] Because the fresh air inlet area 112 is smaller than the circulating air inlet area 111, in this utility model, the negative ion generator 430 is located in the circulating air inlet area 111 in the front visual projection direction. In this way, the negative ion generator 430 does not need to occupy the space in the fresh air inlet area 112, thus avoiding obstruction of the entry of fresh air.

[0044] Based on the disclosure and teachings of the above specification, those skilled in the art can make changes and modifications to the above embodiments. Therefore, this utility model is not limited to the specific embodiments disclosed and described above, and some modifications and changes to this utility model should also fall within the protection scope of the claims of this utility model. Furthermore, although some specific terms are used in this specification, these terms are only for convenience of explanation and do not constitute any limitation on this utility model.
