[0026] In order 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 described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work should fall within the scope of protection of the present application.

[0027] See also Figures 1 to 9As shown, according to an embodiment of the present invention, the present invention provides an elevator car, 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, 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 arranged at intervals 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 to enter 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 arranged at intervals 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 to enter the elevator car. Among them, when the elevator car rises, an air pressure difference is formed at the top of the car body 1, so that the air enters the car body 1 through the first air duct 4 after heat exchange through the first heat exchange device 2; when the elevator car descends, an air pressure difference is formed at the bottom of the car body 1, so that the air enters the car body 1 through the second air duct 5 after heat exchange through the second heat exchange device 3.

[0028] It can be seen that the elevator car provided by the present invention is mainly composed 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, wherein at least two first air ducts 4 are provided at the top of the car body 1, and at least two first air ducts 4 are arranged at intervals along a first preset direction; at least two second air ducts 5 are provided at the bottom of the car body 1, and at least two second air ducts 5 are arranged at intervals along a first preset direction. At the same time, the first heat exchange device 2 is installed on the car body 1, and the first heat exchange device 2 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 the second heat exchange device 3 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. It can be seen that 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 when the elevator is running can be used to naturally guide the air circulation, reduce the dependence on the motor and the fan, thereby reducing energy consumption and realizing an effective replacement for the heat exchange of the traditional elevator air-conditioning motor-driven fan. At the same time, 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, it can also ensure that the air is evenly distributed inside the car, avoiding local temperature and humidity unevenness, thereby improving the comfort of passengers. 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 can achieve more efficient air heat exchange and facilitate installation and maintenance by the staff. At the same time, by utilizing the air pressure difference generated when the elevator is running to naturally guide the air circulation, not only the car structure is simplified, the maintenance cost is reduced, but also the service life of the elevator car is extended. Due to the reduction of mechanical components such as motors and fans, the failure rate is significantly reduced, and the reliability of the elevator car is improved. In addition, by reducing the use of motors and fans, the noise during elevator operation is reduced, providing passengers with a quieter riding environment. In addition, through natural ventilation and efficient heat exchange, power consumption is effectively reduced, energy saving and cost reduction are achieved, and the requirements of low-carbon environmental protection are met. The elevator car of the present invention can effectively solve the technical problem of conventional elevator air conditioners using motors to drive fans for heat exchange in the prior art.

[0029] Optionally, the first heat exchange device 2 and the second heat exchange device 3 are both located on the outer wall of the car body 1 .

[0030] Optionally, when the elevator car rises or descends, the change in its speed and direction of movement will cause a pressure difference between the inside and outside of the car body. This pressure difference promotes air flow. Specifically: When the elevator car rises, negative pressure (low-pressure area) will be generated in the top space of the car body 1. This is because the air above the car is quickly pushed away during the elevator rise, forming a low-pressure area. At the same time, positive pressure (high-pressure area) will be generated in the bottom space of the car body 1. This is because the air below the car is compressed during the elevator rise, forming a high-pressure area. Due to the negative pressure at the top and the positive pressure at the bottom, the fresh air outside will be forced to quickly pass through the first heat exchange device 2 for heating or cooling, and then enter the car body 1 through the first air duct 4, while the dirty air in the car body 1 is discharged through the second air duct 5 at the bottom of the car body 1. This process can adjust the temperature in the car to ensure that passengers feel comfortable during the rise.

[0031] When the elevator car descends, positive pressure (high pressure area) will be generated in the top space of the car body 1. This is because the air above the car is compressed during the descent of the elevator, forming a high pressure area. At the same time, negative pressure (low pressure area) will be generated in the bottom space of the car body 1. This is because the air below the car is quickly pushed away during the descent of the elevator, forming a low pressure area. Due to the positive pressure at the top and the negative pressure at the bottom, the fresh air outside will be forced to quickly pass through the second heat exchange device 3 for heating or cooling, and then enter the car body 1 through the second air duct 5, while the dirty air in the car body 1 is discharged through the first air duct 4 at the top of the car body 1. In this case, the air enters the interior of the car body 1 through the second air duct 5 to maintain a suitable environment in the car body 1.

[0032] Furthermore, the first air duct 4 and the second air duct 5 both 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°.

[0033] The first preset direction refers to the direction in which the first air duct 4 and the second air duct 5 are arranged on the car body 1 in the elevator car design. This direction is preset, usually to ensure the uniformity and effectiveness of air flow. 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.

[0034] Alternatively, if Figure 4 As shown, there are multiple first air ducts 4 and 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 plurality of first air ducts 4 and the plurality of second air ducts 5 are arranged at intervals along the length direction of the car body 1 (i.e. Figure 4 in the direction indicated by arrow B).

[0035] 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.

[0036] Specifically, the elevator car also includes: a control device, which is used to determine the current operating state of the elevator car, obtain the current load-bearing weight of the elevator car, and adaptively control 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 and / or the current load-bearing weight of the elevator car. With such a structural setting, by setting a control device, the opening and closing of each first air duct 4 and each second air duct 5 can be dynamically adjusted according to the current operating state of the elevator car and / or the current load-bearing weight of the elevator car, thereby reducing unnecessary air circulation and reducing energy consumption. By accurately controlling the opening and closing of each first air duct 4 and each second air duct 5, it is possible to ensure uniform distribution of air in the car, improve heat exchange efficiency, and further save energy. Thereby improving the comfort of passengers and achieving the effect of energy saving and emission reduction.

[0037] Optionally, the control device first determines the current operating state of the elevator car, and then selects whether to obtain the current load-bearing weight of the elevator car according to the current operating state of the elevator car. When the current operating state of the elevator car is ascending or descending, the current load-bearing weight of the elevator car is obtained, and then the opening and closing of each first air duct 4 and / or each second air duct 5 is adaptively controlled according to the current operating state of the elevator car and the current load-bearing weight of the elevator car. When the current operating state of the elevator car is the standby state, the control device directly controls each first air duct 4 and each second air duct 5 to be completely closed.

[0038] Specifically, Figure 5 As shown, the elevator car also includes: a first blocking device 6, which is arranged on the top of the car body 1, and the first blocking device 6 has at least two first blocking plates 61, each of which is arranged in a one-to-one correspondence with each first air duct 4, and each of which is used to block or avoid the corresponding first air duct 4; the control device is connected to each of the first blocking plates 61, and the control device controls the opening and closing of each of the first air ducts 4 by controlling the movement of each of the first blocking plates 61. With such a structural setting, each of the first blocking plates 61 is arranged in a one-to-one correspondence with the corresponding first air duct 4, and the control device can independently control the movement of each of the first blocking plates 61 to achieve accurate opening and closing of each of the first air ducts 4. And according to the operating state of the elevator and the number of passengers, a specific first air duct 4 can be selectively opened or closed to provide more flexible air circulation control. At the same time, the precise control of the first blocking plate 61 can ensure the uniform distribution of air in the car, improve the heat exchange efficiency, and further save energy.

[0039] When the control device controls each first blocking plate 61 to block the corresponding first air duct 4, each first air duct 4 is in a closed state. When the control device controls each first blocking plate 61 to avoid the corresponding first air duct 4, each first air duct 4 is in an open state.

[0040] Optionally, when it is not necessary to allow external air to enter the car body 1 from each first air duct 4 (i.e., when the elevator car is in a standby state), the control device controls each first blocking plate 61 to move so that each first blocking plate 61 blocks the corresponding first air duct 4, so that each first air duct 4 is in a closed state. When the elevator car is in an ascending state and there are fewer people, it is necessary to reduce the entry of external air into the car body 1 from the top. At this time, the control device controls the first blocking plate 61 corresponding to at least one first air duct 4 in each first air duct 4 to move, so as to avoid at least one first air duct 4 in each first air duct 4, so that at least one first air duct 4 in each first air duct 4 is in an open state. At the same time, the control device controls the first blocking plates 61 corresponding to other first air ducts 4 in each first air duct 4 to move, so as to block other first air ducts 4 in each first air duct 4, so that other first air ducts 4 in each first air duct 4 are in a closed state.

[0041] Specifically, at least two first air ducts 4 are divided into two groups, namely the first group and the second group, the first group and the second group respectively include at least one first air duct 4; the first air duct 4 in the first group and the first air duct 4 in the second group are alternately arranged along the first preset direction; the first blocking device 6 also includes: a first driving member and a second driving member, the first driving member is connected to the first air duct 4 in the first group; the first driving member is used to drive the first blocking plate 61 corresponding to the first air duct 4 in the first group to move synchronously; the second driving member is connected to the first blocking plate 61 corresponding to the first air duct 4 in the second group; the second driving member is used to drive the first blocking plate 61 corresponding to the first air duct 4 in the second group to move synchronously; wherein the control device is connected to the first driving member and the second driving member respectively, and the control device is used to control the movement of the first driving member and the second driving member. With such a structural setting, the first air duct 4 is divided into two groups, the first group and the second group respectively include 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. And the first air ducts 4 of the first group and the second group are alternately arranged along the first preset direction, which can ensure the uniform distribution of air in the car. At the same time, the first driving member and the second driving member are respectively driven and connected to the first blocking plates 61 corresponding to the first air ducts 4 of the first group and the second group, which can ensure that the first blocking plates 61 corresponding to each group of first air ducts 4 can move synchronously. In addition, the control device controls the movement of the first driving member and the second driving member according to the operating state of the elevator and the number of passengers, so as to dynamically adjust the opening and closing states of the first and second groups of the first air ducts 4, improve the flexibility of the elevator car, and at the same time ensure the uniform distribution of air in the car body 1, improve the heat exchange efficiency, and further save energy.

[0042] Alternatively, if Figure 5 As shown, there are multiple first air ducts 4, and the multiple first air ducts 4 are arranged in sequence along the length direction (the direction indicated by arrow B) of the car body 1. The multiple first air ducts 4 are divided into two groups, specifically a first group and a second group, and each first air duct 4 in the first group and the first air duct 4 in the second group are alternately arranged.

[0043] Alternatively, if Figure 5 As shown, each first air duct 4 in the first group is a first air duct 4 located at an odd number (ie, air inlet A1 ), and the first air duct 4 in the second group is a first air duct 4 located at an even number (ie, air inlet A2 ).

[0044] Specifically, Figure 6 and Figure 7As shown, the first blocking device 6 also includes: at least two first rotating shafts 62, at least two first rotating shafts 62 are respectively arranged in one-to-one correspondence with at least two first air ducts 4 and at least two first blocking plates 61; each first rotating shaft 62 is rotatably arranged on the top of the car body 1, and each first blocking plate 61 is arranged on the corresponding first rotating shaft 62, so that the corresponding first blocking plate 61 is driven to move by the rotation of each first rotating shaft 62, so that each first blocking plate 61 blocks or avoids the corresponding first air duct 4; wherein, the first driving member is drivingly 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; the second driving member is drivingly 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 such a structural setting, by setting each first rotating shaft 62, the first blocking plate 61 corresponding to each first rotating shaft 62 can be driven to move, thereby achieving blocking or avoiding the first air duct 4. This action directly affects the air circulation and adjusts the temperature and air quality in 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, so as to flexibly adjust the air flow in the car body 1. This control can be adjusted according to the operating state of the elevator car and the change of load-bearing weight to optimize the comfort experience of passengers. At the same time, each first rotating shaft 62 is connected to a driving member, which can realize automated and intelligent operation. Through control instructions, each first rotating shaft 62 can accurately control the movement of the corresponding first blocking plate 61 to respond to passenger needs or environmental changes.

[0045] Furthermore, each first rotating shaft 62 is located at one side of the corresponding first air duct 4, one end of the first blocking plate 61 is installed on the first rotating shaft 62, the other end of the first blocking plate 61 is a free end, and the other end of the first blocking plate 61 is arranged toward the other side of the first air duct 4.

[0046] Specifically, the elevator car also includes: a second blocking device 7, which is arranged at the bottom of the car body 1, and the second blocking device 7 has at least two second blocking plates 71, each second blocking plate 71 is arranged in a one-to-one correspondence with each second air duct 5, and each second blocking plate 71 is used to block or avoid the corresponding second air duct 5; the control device is respectively connected to each second blocking plate 71, and the control device controls the opening and closing of each second air duct 5 by controlling the movement of each second blocking plate 71. With such a structural setting, each second blocking plate 71 is arranged in a one-to-one correspondence with the corresponding second air duct 5, and the control device can independently control the movement of each second blocking plate 71 to achieve accurate opening and closing of each second air duct 5. And according to the operating state of the elevator and the number of passengers, a specific second air duct 5 can be selectively opened or closed to provide more flexible air circulation control. At the same time, the precise control of the second blocking plate 71 can ensure the uniform distribution of air in the car, improve the heat exchange efficiency, and further save energy.

[0047] When the control device controls each second blocking plate 71 to block the corresponding second air duct 5, each second air duct 5 is in a closed state. When the control device controls each second blocking plate 71 to avoid the corresponding second air duct 5, each second air duct 5 is in an open state.

[0048] Optionally, when it is not necessary to allow external air to enter the car body 1 from each second air duct 5 (i.e., when the elevator car is in a standby state), the control device controls each second blocking plate 71 to move so that each second blocking plate 71 blocks the corresponding second air duct 5, so that each second air duct 5 is in a closed state. When the elevator car is in a descending state and there are fewer people, it is necessary to reduce the external air from entering the car body 1 from the bottom. At this time, the control device controls the second blocking plate 71 corresponding to at least one second air duct 5 of each second air duct 5 to move, so as to avoid at least one second air duct 5 of each second air duct 5, so that at least one second air duct 5 of each second air duct 5 is in an open state. At the same time, the control device controls the second blocking plates 71 corresponding to other second air ducts 5 in each second air duct 5 to move, so as to block other second air ducts 5 in each second air duct 5, so that other second air ducts 5 of each second air duct 5 are in a closed state.

[0049] 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 duct 5 in the third group and the second air duct 5 in the fourth group are alternately arranged along the first preset direction; the second blocking device 7 also includes: a third driving member and a fourth driving member, the third driving member is drivingly connected to the second blocking plate 71 corresponding to the second air duct 5 in the third group; the third driving member is used to drive the second blocking plate 71 corresponding to the second air duct 5 in the third group to move synchronously; the fourth driving member is drivingly connected to the second blocking plate 71 corresponding to the second air duct 5 in the fourth group; the fourth driving member is used to drive the second blocking plate 71 corresponding to the second air duct 5 in the fourth group to move synchronously; wherein the 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 such a structural setting, the second air duct 5 is divided into two groups, and the third group and the fourth group respectively include 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. And the second air ducts 5 of the third and fourth groups are alternately arranged along the first preset direction, which can ensure the uniform distribution of air in the car. At the same time, the third driving member and the fourth driving member are respectively connected to the second blocking plates 71 corresponding to the second air ducts 5 of the third and fourth groups, which can ensure that the second blocking plates 71 corresponding to each group of second air ducts 5 can move synchronously. In addition, the control device controls the movement of the third driving member and the fourth driving member according to the operating state of the elevator and the number of passengers, so as to dynamically adjust the opening and closing states of the second air ducts 5 of the third and fourth groups, improve the flexibility of the elevator car, and also ensure the uniform distribution of air in the car body 1, improve the heat exchange efficiency, and further save energy.

[0050] Alternatively, if Figure 5 As shown, there are multiple second air ducts 5, and the multiple second air ducts 5 are arranged in sequence along the width direction (the direction indicated by arrow B) of the car body 1. The multiple second air ducts 5 are divided into two groups, specifically the third group and the fourth group, and each second air duct 5 in the third group is alternately arranged with the second air duct 5 in the fourth group.

[0051] Alternatively, if Figure 5 As shown, each second air duct 5 in the third group is a second air duct 5 located at an odd number (ie, the air inlet B1 ), and the second air duct 5 in the second group is a second air duct 5 located at an even number (ie, the air inlet B2 ).

[0052] Specifically, Figure 8 and Fig. 9As shown, the second blocking device 7 also includes: at least two second rotating shafts 72, at least two second rotating shafts 72 are respectively arranged in one-to-one correspondence with at least two second air ducts 5 and at least two second blocking plates 71; each second rotating shaft 72 is rotatably arranged at the bottom of the car body 1, and each second blocking plate 71 is arranged on the corresponding second rotating shaft 72, so that the corresponding second blocking plate 71 is driven to move by the rotation of each second rotating shaft 72, so that each second blocking plate 71 blocks or avoids the corresponding second air duct 5; wherein, the third driving member is drivingly 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; the fourth driving member is drivingly 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 such a structural setting, by setting each second rotating shaft 72, the second blocking plate 71 corresponding to each second rotating shaft 72 can be driven to move, thereby achieving blocking or avoiding the second air duct 5. This action directly affects the air circulation and adjusts the temperature and air quality in 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, thereby flexibly adjusting the air flow in the car body 1. This control can be adjusted according to the operating state of the elevator car and the change in load-bearing weight to optimize the comfort experience of passengers. At the same time, each second rotating shaft 72 is connected to a drive member, which can realize automated and intelligent operation. Through control instructions, each second rotating shaft 72 can accurately control the movement of the corresponding second blocking plate 71 to respond to passenger needs or environmental changes.

[0053] Furthermore, each second rotating shaft 72 is located at one side of the corresponding second air duct 5 , one end of the second sealing plate 71 is installed 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 arranged toward the other side of the second air duct 5 .

[0054] Specifically, Figures 1 to 4 As shown, the elevator car also includes: a weight sensor 8, which is arranged at the bottom of the car body 1, and is used to detect the load-bearing weight of the elevator car; the weight sensor 8 is connected to the control device, and the weight sensor 8 sends the detected load-bearing weight of the elevator car to the control device. With such a structural setting, the weight sensor 8 can accurately detect the load-bearing weight of the car body 1, so that the control device can adjust the air intake according to the operating state of the elevator car and the current load-bearing weight, further optimizing passenger comfort and elevator energy consumption.

[0055] Further, the weight sensor 8 is located at one side of the car body 1 .

[0056] Optionally, the working process of the elevator car is: When the elevator car is ready to run, the current running state of the elevator car is determined.

[0057] If the current running state of the elevator car is the ascending state, the control device obtains 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 according to the current load weight of the elevator car. Specifically: When the current load-bearing weight of the elevator car is large, it means that there are many passengers. At this time, the control device drives the first drive member, the second drive member, the third drive member and the fourth drive member to move, so as to drive each first blocking plate 61 and each second blocking plate 71 to move through each first rotating shaft 62 and each second rotating shaft 72, so that each first blocking plate 61 avoids the corresponding first air duct 4, and each second blocking plate 71 avoids the corresponding second air duct 5. Thus, each first air duct 4 and each second air duct 5 are fully opened, and then the air circulation speed is increased, so that the fresh air outside is quickly heated or cooled through the first heat exchange device 2, and then enters the car body 1 through the first air duct 4, while the dirty air in the car body 1 is discharged through the second air duct 5 at the bottom of the car body 1. Thereby, the heat exchange effect is improved and the comfort of passengers is improved.

[0058] When the current load of the elevator car is small, it means that there are few passengers. At this time, the control device drives the first drive member, the second drive member, the third drive member and the fourth drive member to move, so as to drive each first blocking plate 61 and each second blocking plate 71 to move through each first rotating shaft 62 and each second rotating shaft 72. Specifically: When the first driving member synchronously drives the first blocking plate 61 corresponding to the first air duct 4 in the first group to evade, the second driving member synchronously drives the first blocking plate 61 corresponding to the second air duct in the second group to block. Or when the first driving member synchronously drives the first blocking plate 61 corresponding to the first air duct 4 in the first group to block, the second driving member synchronously drives the first blocking plate 61 corresponding to the second air duct in the second group to evade; so that part of the first air duct 4 in each first air duct 4 is in an open state. At the same time, the third driving member and the fourth driving member drive each second blocking plate 71 to evade each second air duct 5, so that each second air duct 5 is fully opened. Through the above control, the amount of air entering the car body 1 can be reduced, and the air intake can be made uniform, further improving the comfort of the passengers.

[0059] When the current load weight of the elevator car is zero, it means that there are no passengers in the car body 1 (it rises to a certain floor to pick up passengers). At this time, the control device drives the first drive member, the second drive member, the third drive member and the fourth drive member to move, so as to drive each first blocking plate 61 and each second blocking plate 71 to move through each first rotating shaft 62 and each second rotating shaft 72. Specifically: The first driving member synchronously drives the first rotating shaft 62 corresponding to the first air duct 4 in the first group to rotate, thereby driving the first blocking plate 61 corresponding to the first air duct 4 in the first group to avoid. At the same time, the second driving member synchronously drives the first rotating shaft 62 corresponding to the first air duct 4 in the second group to rotate, thereby driving the first blocking plate 61 corresponding to the first air duct 4 in the second group to avoid. Thus, all the first air ducts 4 are opened. In addition, the third driving member synchronously drives the second rotating shaft 72 corresponding to the second air duct 5 in the third group to rotate, thereby driving the second blocking plate 71 corresponding to the second air duct 5 in the third group to block. And, the fourth driving member synchronously drives the second rotating shaft 72 corresponding to the second air duct 5 in the fourth group to rotate, thereby driving the second blocking plate 71 corresponding to the second air duct 5 in the fourth group to block. Thus, all the second air ducts 5 are closed. Thus, the heat-exchanged air continues to enter the car body 1, thereby maintaining the temperature of the car body 1.

[0060] If the current running state of the elevator car is the descending state, the control device obtains the current load-bearing 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 according to the current load-bearing weight of the elevator car. Specifically: When the current load-bearing weight of the elevator car is large, it means that there are many passengers. At this time, the control device drives the first drive member, the second drive member, the third drive member and the fourth drive member to move, so that each first blocking plate 61 avoids the corresponding first air duct 4, and each second blocking plate 71 avoids the corresponding second air duct 5. Thus, all the first air ducts 4 and all the second air ducts 5 are fully opened, and then the air circulation speed is increased, so that the external fresh air is quickly heated or cooled through the second heat exchange device 3, and then enters the car body 1 through the second air duct 5, while the dirty air in the car body 1 is discharged through the first air duct 4 at the top of the car body 1. Thereby, the heat exchange effect is improved and the comfort of passengers is improved.

[0061] When the current load of the elevator car is small, it means that there are few passengers. At this time, the control device controls all the first air ducts 4 to be opened, and at the same time controls the second air ducts 5 in the third group or controls the second air ducts 5 in the fourth group to be opened. When the second air ducts 5 in the third group are opened, the second air ducts 5 in the fourth group are closed. When the second air ducts 5 in the third group are closed, the second air ducts 5 in the fourth group are opened.

[0062] When the current load of the elevator car is zero, it means that there are no passengers in 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 be closed and all the second air ducts 5 to be opened, so that the heat-exchanged air continues to enter the car body 1, thereby maintaining the temperature of the car body 1.

[0063] If the current running state of the elevator car is the standby state, it means that there is no passenger in the car body 1 and it is suspended in a certain layer. At this time, the control device controls each first air duct 4 and each second air duct 5 to be completely closed.

[0064] In addition, if the elevator car fails during operation, the control device controls all the first air ducts 4 and all the second air ducts 5 to be opened to provide air circulation.

[0065] The present invention provides an elevator, comprising: an elevator car, the elevator car being the elevator car of the above embodiment. The beneficial effects of the elevator of the present invention are the same as the beneficial effects of the elevator car of the above embodiment, which will not be described in detail here.

[0066] The present invention provides a control method, which is applied to the elevator car of the above embodiment. Fig.10 As shown, the control method includes: S11, when the elevator car is ready to run, the current running state of the elevator car is determined.

[0067] S12, 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.

[0068] By adopting such a control method, the air circulation inside the elevator car can be precisely controlled by actively adjusting the opening and closing of the air duct according to the current operating state of the elevator car, thereby improving the comfort of passengers. Intelligently controlling the opening and closing of the air duct can effectively reduce unnecessary energy consumption and optimize the overall energy efficiency of the elevator. This control method can respond to the operating changes of the elevator car in real time, ensure that the state of the air duct matches the movement state of the car, and enhance the flexibility and adaptability of the system.

[0069] Specifically, the method of 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 the standby state, controlling each first air duct 4 and each second air duct 5 to be completely closed; if the current operating state of the elevator car is the ascending state or the descending state, obtaining the current load-bearing weight of the elevator car, so as to selectively control the opening and closing of each first air duct 4 and / or each second air duct 5 according to the current load-bearing weight of the elevator car. With such a control method, in the standby state, closing all air ducts (the first air duct 4 and the second air duct 5) can reduce the energy consumption of the elevator in the no-load state and improve energy efficiency. At the same time, the temperature in the car body 1 can be maintained. In the ascending or descending state, adjusting the opening and closing of the air duct according to the current load-bearing weight can better meet the demand for air circulation under different load conditions and improve the comfort of passengers. At the same time, selectively controlling the opening and closing of the air duct can more effectively manage the air flow in the car, avoid changes in temperature and humidity caused by different loads, and maintain the comfort of the environment in the car.

[0070] Specifically, at least two first air ducts 4 are divided into two groups, namely a first group and a second group, 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, a current load-bearing weight of the elevator car is obtained, and a 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-bearing weight of the elevator car includes: if the current operating state of the elevator car is an ascending state, and the current load-bearing weight of the elevator car is greater than or equal to a preset value, controlling each All the first air ducts 4 and all the second air ducts 5 are opened, so that the air enters the car body 1 through each first air duct 4 after heat exchange by the first heat exchange device 2; if the current running state of the elevator car is the rising state, the current load-bearing weight of the elevator car is less than the preset value and greater than zero, the first air duct 4 in the first group or the first air duct 4 in the second group is controlled to be opened; and, all the second air ducts 5 are controlled to be opened; if the current running state of the elevator car is the rising state, the current load-bearing weight of the elevator car is equal to zero, all the first air ducts 4 are controlled to be opened; and, all the second air ducts 5 are controlled to be closed; wherein the preset value is greater than zero. By adopting such a control method, by dividing the first air duct 4 into two groups and alternately arranging them along the first preset direction, the uniform distribution of the airflow can be enhanced, the air circulation in the elevator car can be optimized, and the overall comfort can be improved. At the same time, when the current load-bearing weight of the elevator car is less than the preset value and greater than zero, the first air duct 4 in the first group or the first air duct 4 in the second group is controlled to be opened, which can reduce the air intake and make the air intake uniform, thereby further improving the comfort of the passengers. And, when the current load weight of the elevator car is zero, all the first air ducts 4 are controlled to be opened; and all the second air ducts 5 are controlled to be closed. The heat-exchanged air can be continuously ventilated into the car body 1, thereby providing a more comfortable environment for passengers entering the car. In addition, according to the current load weight of the elevator car, the opening and closing of the air ducts are dynamically adjusted, which can effectively save energy while ensuring the comfort of passengers.

[0071] The preset value is usually set to compare with the current load-bearing weight of the elevator car, so as to achieve intelligent and efficient control.

[0072] Optionally, when the current load-bearing weight of the elevator car is greater than or equal to a preset value, it indicates that there are many passengers. When the current load-bearing weight of the elevator car is less than the preset value and greater than zero, it indicates that there are few passengers. When the current load-bearing weight of the elevator car is equal to zero, it indicates that the elevator car is in an empty state or is going to a certain floor to pick up passengers.

[0073] Optionally, if the current running state of the elevator car is the ascending state, and the current load-bearing weight of the elevator car is less than a preset value and greater than zero, when the first air duct 4 in the first group is controlled to be opened, the first air duct 4 in the second group is controlled to be closed. Alternatively, when the first air duct 4 in the second group is controlled to be opened, the first air duct 4 in the first group is controlled to be closed. After the air is heat exchanged by the first heat exchange device 2, it flows into the car body 1 through the first air duct 4 in the opened state in each of the first air ducts 4.

[0074] Specifically, at least two second air ducts 5 are divided into two groups, namely a third group and a 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, a current load-bearing weight of the elevator car is obtained, and a 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-bearing weight of the elevator car includes: if the current operating state of the elevator car is a descending state, and the current load-bearing weight of the elevator car is greater than or equal to a preset value, controlling each All the first air ducts 4 and all the second air ducts 5 are opened, so that the air enters the car body 1 through each second air duct 5 after heat exchange by the second heat exchange device 3; if the current running state of the elevator car is the descending state, the current load-bearing weight of the elevator car is less than the preset value and greater than zero, all the first air ducts 4 are controlled to be opened; and the second air ducts 5 in the third group or the second air ducts 5 in the fourth group are controlled to be opened; if the current running state of the elevator car is the descending state, the current load-bearing weight of the elevator car is equal to zero, all the first air ducts 4 are controlled to be closed; and all the second air ducts 5 are controlled to be opened; wherein the preset value is greater than zero. By adopting such a control method, by dividing the second air duct 5 into two groups and alternately arranging them along the first preset direction, the uniform distribution of the airflow can be enhanced, the air circulation in the elevator car can be optimized, and the overall comfort can be improved. At the same time, when the current load-bearing weight of the elevator car is less than the preset value and greater than zero, the second air duct 5 in the third group or the second air duct 5 in the fourth group is controlled to be opened, which can reduce the air intake and make the air intake uniform, thereby further improving the comfort of the passengers. And, when the current load weight of the elevator car is zero, all the second air ducts 5 are controlled to be opened; and all the first air ducts 4 are controlled to be closed. The heat-exchanged air can be continuously ventilated into the car body 1, thereby providing a more comfortable environment for passengers entering the car. In addition, according to the current load weight of the elevator car, the opening and closing of the air ducts are dynamically adjusted, which can effectively save energy while ensuring the comfort of passengers.

[0075] Optionally, if the current running state of the elevator car is the descending state, and the current load-bearing weight of the elevator car is less than a preset value and greater than zero, when the second air duct 5 in the third group is controlled to be opened, the second air duct 5 in the fourth group is controlled to be closed. Alternatively, when the second air duct 5 in the fourth group is controlled to be opened, the second air duct 5 in the third group is controlled to be closed. After the air is heat exchanged by the second heat exchange device 3, it flows into the car body 1 through the second air duct 5 in the opened state in each second air duct 5.

[0076] Specifically, the control method further includes: if the elevator car fails during operation, all the first air ducts 4 and all the second air ducts 5 are controlled to be fully opened. With such a control method, when the elevator fails, all the air ducts are immediately opened to ensure that there is enough fresh air circulation in the car to prevent passengers from feeling uncomfortable due to lack of oxygen or poor air quality. In addition, in the event of a failure, all the air ducts are fully opened to quickly replace the air in the car, remove the dirty air, and keep the air fresh, thereby protecting the health of passengers.
