[0002] Currently, air conditioning products are widely used in hotels, office buildings, hospitals, transportation agencies, and research institutions. The basic principle of air conditioning is to use a motor-driven fan to deliver indoor air or a mixture of indoor and outdoor air to a heat exchanger for cooling or heating, thereby regulating the indoor temperature to meet people's comfort needs. With the increase in high-rise buildings, the application of elevator air conditioning is also becoming increasingly common.

[0024] Beneficial effects:

[0025] Applying the technical solution of this invention, the elevator car provided by this invention mainly comprises a car body, a first heat exchange device, a second heat exchange device, at least two first air ducts, and at least two second air ducts.

[0038] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present application.

[0039] Please see Figures 1 to 9As shown in the embodiment of the present invention, an elevator car is provided, comprising: a car body 1, a first heat exchange device 2, a second heat exchange device 3, at least two first air ducts 4 and at least two second air ducts 5, wherein the first heat exchange device 2 and the second heat exchange device 3 are both installed on the elevator car; the first heat exchange device 2 is located at the top of the car body 1, and the second heat exchange device 3 is located at the bottom of the elevator car; at least two first air ducts 4 are opened at the top of the elevator car; at least two first air ducts 4 are spaced apart along a first preset direction; each first air duct 4 is used to guide the air after heat exchange by the first heat exchange device 2 into the elevator car; at least two second air ducts 5 are opened at the bottom of the elevator car; at least two second air ducts 5 are spaced apart along the first preset direction; each second air duct 5 is used to guide the air after heat exchange by the second heat exchange device 3 into the elevator car. When the elevator car rises, an air pressure difference is formed at the top of the car body 1, so that the air is heated by the first heat exchange device 2 and then enters the car body 1 through the first air duct 4; when the elevator car descends, an air pressure difference is formed at the bottom of the car body 1, so that the air is heated by the second heat exchange device 3 and then enters the car body 1 through the second air duct 5.

[0040] As can be seen, the elevator car provided by the present invention mainly consists of a car body 1, a first heat exchange device 2, a second heat exchange device 3, at least two first air ducts 4, and at least two second air ducts 5. At least two first air ducts 4 are provided on the top of the car body 1, and the at least two first air ducts 4 are spaced apart along a first preset direction. At least two second air ducts 5 are provided on the bottom of the car body 1, and the at least two second air ducts 5 are spaced apart along the first preset direction. Meanwhile, the first heat exchange device 2 is installed on the car body 1 and is located at the top of the car body 1; the second heat exchange device 3 is also installed on the car body 1 and is located at the bottom of the car body 1; the first heat exchange device 2 and the second heat exchange device 3 are arranged opposite to each other. Therefore, by setting the first air duct 4 at the top of the car body 1 and the second air duct 5 at the bottom of the car body 1, the air pressure difference generated during elevator operation can be used to naturally guide air circulation, reducing reliance on motors and fans, thereby reducing energy consumption and effectively replacing the heat exchange of traditional elevator air conditioning motor-driven fans. Simultaneously, setting the first air duct 4 at the top of the car body 1 and the second air duct 5 at the bottom of the car body 1 ensures uniform air distribution inside the car, avoiding uneven local temperature and humidity, thus improving passenger comfort. Installing the first heat exchange device 2 and the second heat exchange device 3 at the top and bottom of the car body 1 respectively enables more efficient air heat exchange and facilitates installation and maintenance by staff. Furthermore, by utilizing the air pressure difference generated during elevator operation to naturally guide air circulation, not only is the car structure simplified and maintenance costs reduced, but the service life of the elevator car is also extended. Due to the reduction of mechanical components such as motors and fans, the failure rate is significantly reduced, improving the reliability of the elevator car. Furthermore, by reducing the use of motors and fans, the noise level during elevator operation is lowered, providing passengers with a quieter riding environment. Additionally, through natural ventilation and efficient heat exchange, electricity consumption is effectively reduced, achieving energy conservation and cost reduction, meeting the requirements of low-carbon and environmental protection. The elevator car of this invention effectively solves the technical problem of traditional elevator air conditioning systems that rely on motor-driven fans for heat exchange.

[0041] Optionally, both the first heat exchange device 2 and the second heat exchange device 3 are located on the outer wall of the car body 1.

[0042] Optionally, when the elevator car ascends or descends, the change in its speed and direction creates a pressure difference between the interior and exterior of the car. This pressure difference promotes airflow. Specifically:

[0043] When the elevator car ascends, a negative pressure (low-pressure area) is generated in the top space of the car body 1. This is because during the elevator's ascent, the air above the car is rapidly pushed aside, forming a low-pressure zone. Simultaneously, a positive pressure (high-pressure area) is generated in the bottom space of the car body 1. This is because during the elevator's ascent, the air below the car is compressed, forming a high-pressure zone. Due to the negative pressure at the top and the positive pressure at the bottom, fresh outside air is forced to rapidly pass through the first heat exchanger 2 for heating or cooling, and then enters the car body 1 through the first air duct 4, while stale air inside the car body 1 is exhausted through the second air duct 5 at the bottom of the car body 1. This process regulates the temperature inside the car, ensuring passenger comfort during the ascent.

[0044] When the elevator car descends, positive pressure (high-pressure area) is generated in the top space of the car body 1. This is because the air above the car is compressed during the descent, forming a high-pressure zone. Simultaneously, negative pressure (low-pressure area) is generated in the bottom space of the car body 1. This is because the air below the car is rapidly pushed aside during the descent, forming a low-pressure zone. Due to the positive pressure at the top and the negative pressure at the bottom, fresh outside air is forced to quickly pass through the second heat exchanger 3 for heating or cooling, and then enters the car body 1 through the second air duct 5, while stale air inside the car body 1 is exhausted through the first air duct 4 at the top of the car body 1. In this situation, air enters the interior of the car body 1 through the second air duct 5 to maintain a suitable environment inside the car body 1.

[0045] Furthermore, both the first air duct 4 and the second air duct 5 extend along a second preset direction, and the first preset direction and the second preset direction form a preset angle, which is greater than 0° and less than 180°. Preferably, the preset angle is 90°.

[0046] The first preset direction refers to the arrangement direction of the first air duct 4 and the second air duct 5 on the car body 1 in the elevator car design. This direction is predetermined, usually to ensure the uniformity and effectiveness of airflow. The second preset direction refers to the extension direction of the first air duct 4 and the second air duct 5 on the car body 1.

[0047] Optionally, such as Figure 4 As shown, there are multiple first air ducts 4 and multiple second air ducts 5. Each first air duct 4 and each second air duct 5 extends along the width direction of the car body 1 (i.e., Figure 4 The direction indicated by the middle arrow A), and multiple first air ducts 4 and multiple second air ducts 5 are all spaced apart along the length of the car body 1 (i.e. Figure 4 (The direction indicated by the middle arrow B).

[0048] Optionally, the first air duct 4 is a first air inlet, and the car body 1 is connected to the first heat exchange device 2 through the first air duct 4. The second air duct 5 is a second air inlet, and the car body 1 is connected to the second heat exchange device 3 through the second air duct 5.

[0049] Specifically, the elevator car also includes a control device for determining the current operating state of the elevator car, obtaining the current load of the elevator car, and adaptively controlling the opening and closing of each first air duct 4 and / or each second air duct 5 based on the current operating state and / or the current load of the elevator car. With this structural arrangement, the control device can dynamically adjust the opening and closing of each first air duct 4 and each second air duct 5 according to the current operating state and / or the current load of the elevator car, thereby reducing unnecessary airflow and lowering energy consumption. Precise control of the opening and closing of each first air duct 4 and each second air duct 5 ensures uniform air distribution within the car, improves heat exchange efficiency, and further saves energy. This enhances passenger comfort while achieving energy conservation and emission reduction.

[0050] Optionally, the control device first determines the current operating state of the elevator car, and then selects whether to acquire the current load weight of the elevator car based on the current operating state. When the current operating state of the elevator car is ascending or descending, the current load weight of the elevator car is acquired, and then the opening and closing of each first air duct 4 and / or each second air duct 5 is adaptively controlled based on the current operating state and the current load weight of the elevator car. When the current operating state of the elevator car is in standby mode, the control device directly controls all first air ducts 4 and each second air duct 5 to close.

[0051] Specifically, such as Figure 5 As shown, the elevator car also includes: a first sealing device 6, which is disposed on the top of the car body 1. The first sealing device 6 has at least two first sealing plates 61, each first sealing plate 61 corresponding to a first air duct 4. Each first sealing plate 61 is used to block or avoid the corresponding first air duct 4. A control device is connected to each first sealing plate 61, and the control device controls the opening and closing of each first air duct 4 by controlling the movement of each first sealing plate 61. With this structural arrangement, by having each first sealing plate 61 correspond to a corresponding first air duct 4, the control device can independently control the movement of each first sealing plate 61, achieving precise opening and closing of each first air duct 4. Furthermore, based on the elevator's operating status and the number of passengers, specific first air ducts 4 can be selectively opened or closed, providing more flexible airflow control. At the same time, the precise control of the first sealing plates 61 can ensure uniform air distribution within the car, improve heat exchange efficiency, and further save energy.

[0052] Specifically, when the control device controls each of the first sealing plates 61 to block the corresponding first air duct 4, the first air duct 4 is in a closed state. When the control device controls each of the first sealing plates 61 to avoid the corresponding first air duct 4, the first air duct 4 is in an open state.

[0053] Optionally, when it is not necessary for external air to enter the car body 1 through each of the first air ducts 4 (i.e., when the elevator car is in standby mode), the control device controls the movement of each of the first blocking plates 61 to block the corresponding first air ducts 4, thus closing the first air ducts 4. When the elevator car is ascending and there are few people, it is necessary to reduce the amount of external air entering the car body 1 from the top. In this case, the control device controls the movement of the first blocking plate 61 corresponding to at least one of the first air ducts 4 to avoid at least one of the first air ducts 4, thus opening at least one of the first air ducts 4. At the same time, the control device controls the movement of the first blocking plates 61 corresponding to the other first air ducts 4 to block the other first air ducts 4, thus closing the other first air ducts 4.

[0054] Specifically, at least two first air ducts 4 are divided into two groups, namely a first group and a second group, each including at least one first air duct 4; the first air ducts 4 in the first group and the first air ducts 4 in the second group are alternately arranged along a first preset direction; the first sealing device 6 further includes: a first driving member and a second driving member, the first driving member being drivenly connected to the first air duct 4 in the first group; the first driving member is used to drive the first sealing plate 61 corresponding to the first air duct 4 in the first group to move synchronously; the second driving member is drivenly connected to the first sealing plate 61 corresponding to the first air duct 4 in the second group; the second driving member is used to drive the first sealing plate 61 corresponding to the first air duct 4 in the second group to move synchronously; wherein, a control device is connected to both the first driving member and the second driving member, and the control device is used to control the movement of the first driving member and the second driving member. With this structural arrangement, the first air ducts 4 are divided into two groups, each including at least one first air duct 4. This grouping design allows the control device to independently control the opening and closing of each group of air ducts. Furthermore, by alternately arranging the first and second groups of first air ducts 4 along a first preset direction, uniform air distribution within the elevator car is ensured. Simultaneously, the first and second driving components are driven and connected to the first sealing plates 61 corresponding to the first and second groups of first air ducts 4, respectively, ensuring synchronized movement of the first sealing plates 61 corresponding to each group of first air ducts 4. In addition, the control device controls the movement of the first and second driving components based on the elevator's operating status and passenger count, thereby dynamically adjusting the opening and closing states of the first and second groups of first air ducts 4. This improves the elevator car's flexibility, ensures uniform air distribution within the car body 1, enhances heat exchange efficiency, and further saves energy.

[0055] Optionally, such as Figure 5 As shown, there are multiple first air ducts 4, which are arranged sequentially at intervals along the length of the car body 1 (in the direction indicated by arrow B). The multiple first air ducts 4 are divided into two groups, specifically a first group and a second group, with each first air duct 4 in the first group and the first air duct 4 in the second group being arranged alternately.

[0056] Optionally, such as Figure 5 As shown, each of the first air ducts 4 in the first group is the odd-numbered first air duct 4 (i.e., air inlet A1), and the first air duct 4 in the second group is the even-numbered first air duct 4 (i.e., air inlet A2).

[0057] Specifically, such as Figure 6 and Figure 7As shown, the first sealing device 6 further includes: at least two first rotating shafts 62, each of which is respectively configured to correspond one-to-one with at least two first air ducts 4 and at least two first sealing plates 61; each first rotating shaft 62 is rotatably mounted on the top of the car body 1, and each first sealing plate 61 is mounted on the corresponding first rotating shaft 62, so that the rotation of each first rotating shaft 62 drives the corresponding first sealing plate 61 to move, thereby blocking or avoiding the corresponding first air ducts 4; wherein, a first driving member is drivenly connected to the first rotating shaft 62 corresponding to the first air duct 4 in the first group, and the first driving member is used to drive the first rotating shaft 62 corresponding to the first air duct 4 in the first group to rotate; a second driving member is drivenly connected to the first rotating shaft 62 corresponding to the first air duct 4 in the second group, and the second driving member is used to drive the first rotating shaft 62 corresponding to the first air duct 4 in the second group to rotate. With this structural arrangement, each first rotating shaft 62 drives the corresponding first blocking plate 61 to move, thereby blocking or avoiding the first air duct 4. This action directly affects airflow, regulating the temperature and air quality inside the car body 1. By rotating different first rotating shafts 62, the opening and closing states of each first air duct 4 can be controlled, thus flexibly adjusting the airflow inside the car body 1. This control can be adjusted according to the elevator car's operating status and load changes to optimize passenger comfort. Simultaneously, each first rotating shaft 62 is connected to a drive component, enabling automated and intelligent operation. Through control commands, each first rotating shaft 62 can precisely control the movement of the corresponding first blocking plate 61 to respond to passenger needs or environmental changes.

[0058] Furthermore, each first rotating shaft 62 is located on one side of the corresponding first air duct 4, one end of the first sealing plate 61 is installed on the first rotating shaft 62, the other end of the first sealing plate 61 is a free end, and the other end of the first sealing plate 61 is set towards the other side of the first air duct 4.

[0059] Specifically, the elevator car also includes a second sealing device 7, which is located at the bottom of the car body 1. The second sealing device 7 has at least two second sealing plates 71, each corresponding to a second air duct 5. Each second sealing plate 71 is used to block or avoid the corresponding second air duct 5. A control device is connected to each second sealing plate 71, controlling the opening and closing of each second air duct 5 by controlling the movement of each second sealing plate 71. With this structure, by having each second sealing plate 71 correspond to a specific second air duct 5, the control device can independently control the movement of each second sealing plate 71, achieving precise opening and closing of each second air duct 5. Furthermore, based on the elevator's operating status and passenger volume, specific second air ducts 5 can be selectively opened or closed, providing more flexible airflow control. Simultaneously, precise control of the second sealing plates 71 ensures uniform air distribution within the car, improving heat exchange efficiency and further saving energy.

[0060] Specifically, when the control device controls each of the second sealing plates 71 to block the corresponding second air duct 5, each of the second air ducts 5 is in a closed state. When the control device controls each of the second sealing plates 71 to avoid the corresponding second air duct 5, each of the second air ducts 5 is in an open state.

[0061] Optionally, when it is not necessary for external air to enter the car body 1 through the respective second air ducts 5 (i.e., when the elevator car is in standby mode), the control device controls the movement of each second sealing plate 71 to block the corresponding second air duct 5, thus closing the second air duct 5. When the elevator car is descending and there are few people, it is necessary to reduce the amount of external air entering the car body 1 from the bottom. In this case, the control device controls the movement of the second sealing plate 71 corresponding to at least one second air duct 5 to avoid at least one second air duct 5, thus opening at least one second air duct 5. Simultaneously, the control device controls the movement of the second sealing plates 71 corresponding to other second air ducts 5 to block the other second air ducts 5, thus closing the other second air ducts 5.

[0062] Specifically, at least two second air ducts 5 are divided into two groups, namely a third group and a fourth group, each including at least one second air duct 5; the second air ducts 5 in the third group and the second air ducts 5 in the fourth group are alternately arranged along a first preset direction; the second sealing device 7 further includes: a third driving member and a fourth driving member, the third driving member being drivenly connected to the second sealing plate 71 corresponding to the second air duct 5 in the third group; the third driving member is used to drive the second sealing plate 71 corresponding to the second air duct 5 in the third group to move synchronously; the fourth driving member is drivenly connected to the second sealing plate 71 corresponding to the second air duct 5 in the fourth group; the fourth driving member is used to drive the second sealing plate 71 corresponding to the second air duct 5 in the fourth group to move synchronously; wherein, a control device is connected to the third driving member and the fourth driving member respectively, and the control device is used to control the movement of the third driving member and the fourth driving member. With this structural arrangement, the second air ducts 5 are divided into two groups, the third group and the fourth group each including at least one second air duct 5. This grouping design allows the control device to independently control the opening and closing of each group of air ducts. Furthermore, by alternately arranging the second air ducts 5 of the third and fourth groups along the first preset direction, uniform air distribution within the car is ensured. Simultaneously, the third and fourth drive components are driven and connected to the second sealing plates 71 corresponding to the second air ducts 5 of the third and fourth groups, respectively, ensuring synchronized movement of the second sealing plates 71 corresponding to each group of second air ducts 5. In addition, the control device controls the movement of the third and fourth drive components according to the elevator's operating status and the number of passengers, thereby dynamically adjusting the opening and closing states of the second air ducts 5 of the third and fourth groups. This improves the flexibility of the elevator car, while also ensuring uniform air distribution within the car body 1, improving heat exchange efficiency, and further saving energy.

[0063] Optionally, such as Figure 5 As shown, there are multiple second air ducts 5, which are arranged sequentially at intervals along the width direction of the car body 1 (in the direction indicated by arrow B). The multiple second air ducts 5 are divided into two groups, specifically the third group and the fourth group, with each second air duct 5 in the third group and the second air duct 5 in the fourth group being arranged alternately.

[0064] Optionally, such as Figure 5 As shown, each of the second air ducts 5 in the third group is the odd-numbered second air duct 5 (i.e., air inlet B1), and the second air ducts 5 in the second group are the even-numbered second air ducts 5 (i.e., air inlet B2).

[0065] Specifically, such as Figure 8 and Figure 9As shown, the second sealing device 7 further includes: at least two second rotating shafts 72, each of which is respectively configured to correspond one-to-one with at least two second air ducts 5 and at least two second sealing plates 71; each second rotating shaft 72 is rotatably disposed at the bottom of the car body 1, and each second sealing plate 71 is disposed on the corresponding second rotating shaft 72, so that the rotation of each second rotating shaft 72 drives the corresponding second sealing plate 71 to move, so that each second sealing plate 71 blocks or avoids the corresponding second air duct 5; wherein, a third driving member is drivenly connected to the second rotating shaft 72 corresponding to the second air duct 5 in the third group, and the third driving member is used to drive the second rotating shaft 72 corresponding to the second air duct 5 in the third group to rotate; a fourth driving member is drivenly connected to the second rotating shaft 72 corresponding to the second air duct 5 in the fourth group, and the fourth driving member is used to drive the second rotating shaft 72 corresponding to the second air duct 5 in the fourth group to rotate. With this structural arrangement, each second rotating shaft 72 drives the corresponding second blocking plate 71 to move, thereby blocking or avoiding the second air duct 5. This action directly affects airflow, regulating the temperature and air quality inside the car body 1. By rotating different second rotating shafts 72, the opening and closing states of each second air duct 5 can be controlled, thus flexibly adjusting the airflow inside the car body 1. This control can be adjusted according to the elevator car's operating status and load changes to optimize passenger comfort. Simultaneously, each second rotating shaft 72 is connected to a drive component, enabling automated and intelligent operation. Through control commands, each second rotating shaft 72 can precisely control the movement of the corresponding second blocking plate 71 to respond to passenger needs or environmental changes.

[0066] Furthermore, each second rotating shaft 72 is located on one side of the corresponding second air duct 5, one end of the second sealing plate 71 is mounted on the second rotating shaft 72, the other end of the second sealing plate 71 is a free end, and the other end of the second sealing plate 71 is set towards the other side of the second air duct 5.

[0067] Specifically, such as Figures 1 to 4 As shown, the elevator car also includes a weight sensor 8, which is located at the bottom of the car body 1. The weight sensor 8 is used to detect the load-bearing weight of the elevator car. The weight sensor 8 is connected to the control device and sends the detected load-bearing weight of the elevator car to the control device. With this structural arrangement, the load-bearing weight of the car body 1 can be accurately detected by the weight sensor 8, thereby enabling the control device to adjust the air intake volume according to the operating status of the elevator car and the current load-bearing weight, further optimizing passenger comfort and elevator energy consumption.

[0068] Furthermore, the weight sensor 8 is located on one side of the car body 1.

[0069] Optionally, the elevator car's operating process is as follows:

[0070] When the elevator car is about to start running, determine the current operating status of the elevator car.

[0071] If the elevator car is currently in an ascending state, the control device acquires the current load weight of the elevator car detected by the weight sensor 8, and selectively controls the opening and closing of each first air duct 4 and / or each second air duct 5 based on the current load weight of the elevator car. Specifically:

[0072] When the current load on the elevator car is high, it indicates a large number of passengers. At this time, the control device drives the first, second, third, and fourth drive components to move, which in turn moves the first and second sealing plates 61 and 71 via the first and second rotating shafts 62 and 72, respectively. This causes the first sealing plates 61 to avoid the corresponding first air duct 4, and the second sealing plates 71 to avoid the corresponding second air duct 5. This fully opens the first and second air ducts 4 and 5, increasing the airflow speed. Fresh outside air is quickly heated or cooled by the first heat exchanger 2 and then enters the elevator car body 1 through the first air duct 4, while stale air inside the elevator car body 1 is exhausted through the second air duct 5 at the bottom of the car body 1. This improves heat exchange efficiency and enhances passenger comfort.

[0073] When the current load capacity of the elevator car is low, it indicates that there are few passengers. At this time, the control device drives the first, second, third, and fourth drive components to move, thereby moving the first and second sealing plates 61 and 71 via the first rotating shaft 62 and the second rotating shaft 72. Specifically:

[0074] When the first drive unit synchronously drives the first blocking plate 61 corresponding to the first air duct 4 in the first group to avoid it, the second drive unit synchronously drives the first blocking plate 61 corresponding to the second air duct in the second group to block it. Alternatively, when the first drive unit synchronously drives the first blocking plate 61 corresponding to the first air duct 4 in the first group to block it, the second drive unit synchronously drives the first blocking plate 61 corresponding to the second air duct in the second group to avoid it, thus keeping some of the first air ducts 4 open. At the same time, the third and fourth drive units drive the second blocking plates 71 to avoid the second air ducts 5, so that all the second air ducts 5 are fully open. Through the above control, the amount of air entering the car body 1 can be reduced, and the air intake can be made more uniform, further improving passenger comfort.

[0075] When the current load capacity of the elevator car is zero, it indicates that there are no passengers inside the car body 1 (it ascends to a certain floor to pick up passengers). At this time, the control device drives the first drive component, the second drive component, the third drive component, and the fourth drive component to move, thereby driving the first sealing plate 61 and the second sealing plate 71 to move through the respective first rotating shaft 62 and the respective second rotating shaft 72. Specifically:

[0076] The first driving component synchronously drives the first rotating shaft 62 corresponding to the first air duct 4 in the first group to rotate, thereby causing the first sealing plate 61 corresponding to the first air duct 4 in the first group to avoid obstruction. Simultaneously, the second driving component synchronously drives the first rotating shaft 62 corresponding to the first air duct 4 in the second group to rotate, thereby causing the first sealing plate 61 corresponding to the first air duct 4 in the second group to avoid obstruction. This results in all first air ducts 4 being fully opened. Furthermore, the third driving component synchronously drives the second rotating shaft 72 corresponding to the second air duct 5 in the third group to rotate, thereby causing the second sealing plate 71 corresponding to the second air duct 5 in the third group to seal. And, the fourth driving component synchronously drives the second rotating shaft 72 corresponding to the second air duct 5 in the fourth group to rotate, thereby causing the second sealing plate 71 corresponding to the second air duct 5 in the fourth group to seal. This results in all second air ducts 5 being fully closed. This allows the heat-exchanged air to continuously enter the car body 1, thereby maintaining the temperature of the car body 1.

[0077] If the elevator car is currently in a descending state, the control device acquires the current load weight of the elevator car detected by the weight sensor 8, and selectively controls the opening and closing of each first air duct 4 and / or each second air duct 5 based on the current load weight of the elevator car. Specifically:

[0078] When the current load on the elevator car is high, it indicates a large number of passengers. At this time, the control device drives the first, second, third, and fourth drive components to move, causing each first sealing plate 61 to avoid the corresponding first air duct 4, and each second sealing plate 71 to avoid the corresponding second air duct 5. This fully opens all first and second air ducts 4 and 5, increasing the airflow speed. Fresh outside air is quickly heated or cooled by the second heat exchanger 3 and then enters the elevator car body 1 through the second air duct 5, while stale air inside the elevator car body 1 is exhausted through the first air duct 4 at the top of the elevator car body 1. This improves heat exchange efficiency and enhances passenger comfort.

[0079] When the current load capacity of the elevator car is low, it indicates that there are few passengers. At this time, the control device opens all the first air ducts 4, and simultaneously opens either the second air duct 5 in the third group or the second air duct 5 in the fourth group. Specifically, when the second air duct 5 in the third group is opened, the second air duct 5 in the fourth group is closed; conversely, when the second air duct 5 in the third group is closed, the second air duct 5 in the fourth group is opened.

[0080] When the current load capacity of the elevator car is zero, it means there are no passengers inside the car body 1 (it descends to a certain floor to pick up passengers). At this time, the control device controls all the first air ducts 4 to close completely and all the second air ducts 5 to open completely. This allows the heat-exchanged air to continuously enter the car body 1, thereby maintaining the temperature of the car body 1.

[0081] If the elevator car is currently in standby mode, it means there are no passengers inside the car body 1, and it is stopped on a certain floor. At this time, the control device controls all the first air ducts 4 and all the second air ducts 5 to close completely.

[0082] In addition, if the elevator car malfunctions during operation, the control device will open all the first air ducts 4 and all the second air ducts 5 to provide air circulation.

[0083] This invention provides an elevator, comprising: an elevator car, wherein the elevator car is the elevator car described in the above embodiment. The beneficial effects of the elevator of this invention are the same as those of the elevator car described in the above embodiment, and will not be repeated here.

[0084] This invention provides a control method, which is applied to the elevator car in the above embodiments, such as... Figure 10 As shown, the control methods include:

[0085] S11, when the elevator car is about to start running, determine the current operating status of the elevator car.

[0086] S12, to adaptively control the opening and closing of each first air duct 4 and / or each second air duct 5 according to the current operating status of the elevator car.

[0087] This control method, by actively adjusting the opening and closing of the air ducts according to the current operating status of the elevator car, enables precise control of airflow within the car, thereby improving passenger comfort. Intelligent control of the air duct opening and closing effectively reduces unnecessary energy consumption and optimizes the overall energy efficiency of the elevator. This control method can respond in real-time to changes in the elevator car's operation, ensuring that the air duct status matches the car's movement, enhancing the system's flexibility and adaptability.

[0088] Specifically, a method for adaptively controlling the opening and closing of each first air duct 4 and / or each second air duct 5 according to the current operating state of the elevator car includes: if the current operating state of the elevator car is standby, controlling all first air ducts 4 and each second air duct 5 to close; if the current operating state of the elevator car is ascending or descending, obtaining the current load weight of the elevator car, and selectively controlling the opening and closing of each first air duct 4 and / or each second air duct 5 according to the current load weight. Using this control method, in the standby state, closing all air ducts (first air ducts 4 and second air ducts 5) can reduce the energy consumption of the elevator in the no-load state and improve energy efficiency. At the same time, it can maintain the temperature inside the car body 1. In the ascending or descending state, adjusting the opening and closing of the air ducts according to the current load weight can better meet the air circulation needs under different load conditions and improve passenger comfort. At the same time, selectively controlling the opening and closing of the air ducts can more effectively manage the airflow inside the car, avoid temperature and humidity changes caused by different loads, and maintain the comfort of the environment inside the car.

[0089] Specifically, at least two first air ducts 4 are divided into two groups, namely a first group and a second group, and the first group and the second group respectively include at least one first air duct 4; the first air ducts 4 in the first group and the first air ducts 4 in the second group are alternately arranged along a first preset direction; if the current operating state of the elevator car is an ascending state or a descending state, the current load weight of the elevator car is obtained, and the method for selectively controlling the opening and closing of each first air duct 4 and / or each second air duct 5 according to the current load weight of the elevator car includes: if the current operating state of the elevator car is an ascending state and the current load weight of the elevator car is greater than or equal to a preset value, controlling each All first air ducts 4 and all second air ducts 5 are fully opened, allowing air to enter the elevator car body 1 through each first air duct 4 after heat exchange with the first heat exchange device 2. If the elevator car is currently in an ascending state and its current load is less than a preset value but greater than zero, the first air duct 4 in the first group or the first air duct 4 in the second group is opened; and all second air ducts 5 are opened. If the elevator car is currently in an ascending state and its current load is zero, all first air ducts 4 are opened; and all second air ducts 5 are closed; wherein the preset value is greater than zero. This control method, by dividing the first air ducts 4 into two groups and alternately setting them along a first preset direction, enhances the uniform distribution of airflow, optimizes air circulation within the elevator car, and improves overall comfort. Simultaneously, when the current load of the elevator car is less than a preset value but greater than zero, opening the first air duct 4 in the first group or the first air duct 4 in the second group reduces the intake air volume, making the intake air more uniform, thereby further improving passenger comfort. Furthermore, when the current load of the elevator car is zero, all first air ducts 4 are opened; and all second air ducts 5 are closed. This allows the heat-exchanged air to continuously circulate within the car body 1, providing a more comfortable environment for passengers entering the car. In addition, dynamically adjusting the opening and closing of the air ducts based on the current load of the elevator car effectively saves energy while ensuring passenger comfort.

[0090] The preset value is usually set to compare with the current load of the elevator car, so as to achieve intelligent and efficient control.

[0091] Optionally, when the current load of the elevator car is greater than or equal to a preset value, it indicates that there are many passengers. When the current load of the elevator car is less than the preset value but greater than zero, it indicates that there are few passengers. When the current load of the elevator car is equal to zero, it indicates that the elevator car is empty or is going to a certain floor to pick up passengers.

[0092] Optionally, if the elevator car is currently in an ascending state, and the current load of the elevator car is less than a preset value but greater than zero, when the first air duct 4 in the first group is opened, the first air duct 4 in the second group is closed. Alternatively, when the first air duct 4 in the second group is opened, the first air duct 4 in the first group is closed. This ensures that after the air is heated by the first heat exchanger 2, it flows into the car body 1 through the open first air duct 4.

[0093] Specifically, at least two second air ducts 5 are divided into two groups, namely the third group and the fourth group, and the third group and the fourth group respectively include at least one second air duct 5; the second air ducts 5 in the third group and the second air ducts 5 in the fourth group are alternately arranged along a first preset direction; if the current operating state of the elevator car is an ascending state or a descending state, the current load weight of the elevator car is obtained, and the method for selectively controlling the opening and closing of each first air duct 4 and / or each second air duct 5 according to the current load weight of the elevator car includes: if the current operating state of the elevator car is a descending state, and the current load weight of the elevator car is greater than or equal to a preset value, controlling each All first air ducts 4 and all second air ducts 5 are fully opened, allowing air to pass through the second heat exchanger 3 and then enter the elevator car body 1 through each second air duct 5. If the elevator car is currently in a descending state and its current load is less than a preset value but greater than zero, all first air ducts 4 are opened; and the second air ducts 5 in the third group or the fourth group are also opened. If the elevator car is currently in a descending state and its current load is zero, all first air ducts 4 are closed; and the second air ducts 5 are all opened; wherein the preset value is greater than zero. This control method, by dividing the second air ducts 5 into two groups and alternately setting them along a first preset direction, enhances the uniform distribution of airflow, optimizes air circulation within the elevator car, and improves overall comfort. Simultaneously, when the current load of the elevator car is less than a preset value but greater than zero, opening the second air ducts 5 in the third group or the fourth group reduces the intake air volume, making the intake air more uniform, thereby further improving passenger comfort. Furthermore, when the current load of the elevator car is zero, all second air ducts 5 are opened; and all first air ducts 4 are closed. This allows the heat-exchanged air to continuously circulate within the car body 1, providing a more comfortable environment for passengers entering the car. In addition, dynamically adjusting the opening and closing of the air ducts based on the current load of the elevator car effectively saves energy while ensuring passenger comfort.

[0094] Optionally, if the elevator car is currently in a descending state, and its current load is less than a preset value but greater than zero, when the second air duct 5 in the third group is opened, the second air duct 5 in the fourth group is closed. Alternatively, when the second air duct 5 in the fourth group is opened, the second air duct 5 in the third group is closed. This ensures that after the air is heated by the second heat exchanger 3, it flows into the car body 1 through the open second air ducts 5.

[0095] Specifically, the control method also includes: if a malfunction occurs during elevator car operation, all first air ducts 4 and all second air ducts 5 will be fully opened. This control method ensures that all air ducts open immediately upon elevator malfunction, guaranteeing sufficient fresh air circulation within the car and preventing passenger discomfort due to oxygen deficiency or poor air quality. Furthermore, in the event of a malfunction, the full opening of all air ducts allows for rapid replacement of the air within the car, removing stale air and maintaining fresh air, thereby protecting passenger health.
