[0048] To make the purpose, technical solutions, and advantages of the present invention more clear, the following will be combined with the accompanying drawings to clearly and completely describe the technical solutions of the present invention. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0049] The following combination Figures 1-14 , the outdoor unit provided by the utility model embodiment is described in detail through specific embodiments and application scenarios.

[0050] like Figure 1 、 Figure 2 and Figure 3 As shown, the embodiment of the present invention provides an outdoor unit, comprising: a cabinet 1, a power generation component 4 and a heat exchange device;

[0051] The cabinet 1 has a compartment and an air inlet 121 and an air outlet 122 communicating with the compartment;

[0052] The power generation component 4 includes a solar cell panel 41 and a raindrop friction power generation panel 42, and the solar cell panel 41 and the raindrop friction power generation panel 42 are respectively arranged outside the room;

[0053] The heat exchange device includes an air delivery component, which is located in the compartment and electrically connected to the solar cell panel 41 and the raindrop friction power generation panel 42;

[0054] The air delivery component is used to drive air into the compartment from the air inlet 121 and then be discharged from the air outlet 122 .

[0055] It is understood that the outdoor unit can be an advertising machine, a vending machine, a multi-functional sports machine, etc. The cabinet 1 is used to house the various components configured for the outdoor unit. The cabinet 1 includes a cabinet body 11 and a back panel 12. The back panel 12 is mounted on the open end of the rear side of the cabinet body 11. The cabinet body 11 and the back panel 12 form a compartment. The air inlet 121 and the air outlet 122 can both be constructed on the back panel 12. A filter can be installed at the air inlet 121, and an air grille can be installed at the air outlet 122. The front of the cabinet body 11 is arranged opposite the back panel 12, and various display devices can be installed on the front of the cabinet body 11.

[0056] The solar cell panel 41 and the raindrop friction power generation panel 42 can be arranged on the cabinet 1 or on one side of the cabinet 1, and there is no specific limitation on this.

[0057] The solar panel 41 can be configured in either an inclined or horizontal position, without specific limitation. A solar panel 41, also known as a photovoltaic panel, is a device that directly converts sunlight into electrical energy. Its operating principle is based on the photovoltaic effect, which states that when sunlight strikes a panel made of a semiconductor material (most commonly silicon), photons interact with electrons in the semiconductor material, causing them to transition to the conduction band, thereby generating an electric current.

[0058] The raindrop friction power generation plate 42 is configured to be inclined relative to the horizontal plane so that when raindrops fall on the surface of the raindrop friction power generation plate 42, they can roll under the action of their own gravity, thereby prompting the raindrop friction power generation plate 42 to generate electricity by utilizing the friction and electrostatic effect of raindrops during the sliding process.

[0059] Triboelectric power generation technology is an innovative energy harvesting method that harnesses the energy generated when raindrops land on specially designed surfaces. The triboelectric plate 42 is typically designed with a microstructured surface or a special coating, allowing the raindrops to generate electricity through friction and electrostatic effects as they slide down. Specifically, when a raindrop strikes the surface of the triboelectric plate 42, the plate 42 becomes charged due to the contact and separation of the raindrop. This charge is then collected and converted into usable electrical energy using a specific electrode configuration.

[0060] The air delivery component can be configured to include one or more axial flow fans, and the air delivery component is located in the air flow channel between the air inlet 121 and the air outlet 122; when the air delivery component starts running, the outside air enters the compartment from the air inlet 121 and performs convection heat exchange with various components in the compartment, and the gas after heat exchange is discharged from the air outlet 122.

[0061] From the above, it can be seen that the outdoor unit provided by the present invention is configured with a solar panel 41 and a raindrop friction power generation panel 42, and the solar panel 41 and the raindrop friction power generation panel 42 are electrically connected to the wind transmission component respectively. The solar panel 41 can use sunlight to generate electricity on sunny days, and the raindrop friction power generation panel 42 can use the friction and electrostatic effect of raindrops in the process of sliding down on rainy days to generate electricity. Therefore, whether it is sunny or rainy, the outdoor unit can collect electricity, and use the collected electricity to ensure the normal operation of the wind transmission component and ensure that the various components in the cabinet 1 are in a suitable working environment. It not only meets the normal heat dissipation protection needs of the outdoor unit when not in use, but also saves energy and is environmentally friendly, and extends the service life of the outdoor unit.

[0062] In some embodiments, as Figure 1 and Figure 2 As shown, the solar cell panel 41 and the raindrop friction power generation panel 42 are respectively arranged on the top of the cabinet 1, and are both inclined relative to the horizontal plane.

[0063] It is understandable that by arranging the solar panel 41 at the top of the cabinet 1 in an inclined manner, it is helpful to prevent sunlight from being blocked. The solar panel 41 can effectively receive sunlight radiation at different time periods of the day, thereby ensuring the power generation effect of the solar panel 41.

[0064] By arranging the raindrop friction power generation plate 42 at an inclined manner at the top of the cabinet 1, it is not only beneficial for the raindrop friction power generation plate 42 to fully receive the falling raindrops, but also ensures that when the raindrops fall on the surface of the raindrop friction power generation plate 42, they can fully contact and rub with it and generate electricity.

[0065] At the same time, the arrangement of the solar panel 41 and the raindrop friction power generation panel 42 on the top of the cabinet 1 can prevent sunlight or raindrops from directly acting on the cabinet 1 to a certain extent, which is beneficial to extending the service life of the cabinet 1.

[0066] In some embodiments, as Figure 1 and Figure 2 As shown, there are multiple sets of power generation components 4, and the multiple sets of power generation components 4 are arranged side by side. The solar cell panels 41 and the raindrop friction power generation panels 42 in each set of power generation components 4 are arranged at an angle, so that the multiple sets of power generation components 4 form a human-shaped roof structure.

[0067] It can be understood that in each set of power generation components 4, the bottom end of the solar panel 41 and the bottom end of the raindrop friction power generation plate 42 are far away from each other and are both placed at the top of the cabinet 1. At the same time, the top end of the solar panel 41 and the bottom end of the raindrop friction power generation plate 42 are in contact with each other, so that the solar panel 41 and the raindrop friction power generation plate 42 in each set of power generation components 4 are set at an angle.

[0068] The angle between the solar cell panel 41 and the raindrop friction power generation panel 42 in each power generation assembly 4 can be 30° to 150°, for example, 30°, 60°, 90°, 120° or 150°.

[0069] This embodiment combines multiple sets of power generation components 4 into a human-shaped roof structure, which can meet the normal use requirements of the solar cell panel 41 and the raindrop friction power generation panel 42 while forming physical protection for the cabinet 1 based on the human-shaped roof structure, thereby improving the adaptability of the outdoor unit to different outdoor environments.

[0070] In some embodiments, as Figure 1 As shown, multiple sets of power generation components 4 are arranged side by side along the length direction of the cabinet 1; in each set of power generation components 4, one of the solar cell panel 41 and the raindrop friction power generation panel 42 faces the front side of the cabinet 1, and the other faces the rear side of the cabinet 1;

[0071] The solar cell panels 41 and raindrop friction power generation panels 42 in two adjacent sets of power generation components 4 are oriented in different directions.

[0072] It is understandable that, in each set of power generation components 4 , the solar cell panel 41 and the raindrop friction power generation panel 42 are arranged at the top of the cabinet 1 in a back-to-back manner along the width direction of the cabinet 1 .

[0073] Since each set of power generation components 4 includes a solar cell panel 41 and a raindrop friction power generation panel 42, and multiple sets of power generation components 4 are arranged side by side along the length direction of the cabinet 1, then near the front side of the cabinet 1, a part of the solar cell panels 41 and raindrop friction power generation panels 42 in the multiple sets of power generation components 4 are alternately arranged in sequence along the length direction of the cabinet 1; near the back side of the cabinet 1, another part of the solar cell panels 41 and raindrop friction power generation panels 42 in the multiple sets of power generation components 4 are alternately arranged in sequence along the length direction of the cabinet 1. This design ensures that the solar cell panels 41 and the raindrop friction power generation panels 42 have two layout postures, which is conducive to ensuring the power generation effect.

[0074] In some embodiments, as Figure 4 As shown, the raindrop friction power generation plate 42 includes an electronegative material layer 421, a metal electrode layer 422 and an insulating substrate 423; the electronegative material layer 421, the metal electrode layer 422 and the insulating substrate 423 are stacked in sequence from top to bottom.

[0075] It is understandable that raindrops usually carry positive or negative charges, and the electronegative material layer 421 directly contacts the raindrops to produce charge transfer. The metal electrode layer 422 is used to sense and transmit electrons, and the insulating substrate 423 serves as a carrier for laying out the metal electrode layer 422. The insulating substrate 423 can be a glass substrate.

[0076] Furthermore, the electronegative material layer 421 includes a polytetrafluoroethylene film, and the metal electrode layer 422 includes a copper electrode layer. The electronegative material layer 421 can also be a polyimide layer, and the metal electrode layer 422 can also be an iron electrode layer or a silver electrode layer.

[0077] The following combination Figure 5 , the power generation principle of the raindrop friction power generation plate 42 is explained as follows:

[0078] like Figure 5 It can be seen that when the droplets fall onto the surface of the raindrop friction power generation plate 42, the droplets flow along the surface of the electronegative material layer 421 and rub against it. The whole process goes through five stages: dripping, spreading, shrinking and sliding.

[0079] Specifically, after the liquid droplets fall onto the surface of the electronegative material layer 421 (polytetrafluoroethylene film) (see Figure 5 a1 in the figure), the droplet will quickly spread on the surface of the polytetrafluoroethylene film under the action of gravity (see Figure 5 As shown in b1 in the figure, the contact area of ​​the droplet increases during the spreading process, and friction occurs with the polytetrafluoroethylene film, causing charge transfer. Since the polytetrafluoroethylene film has a strong electronegativity, the first droplet loses electrons and becomes positively charged after friction with the polytetrafluoroethylene film, while the polytetrafluoroethylene film gains electrons and becomes negatively charged (see Figure 5 b1 in the figure) to achieve electrostatic equilibrium. The polytetrafluoroethylene film is hydrophobic, and after spreading on its surface, the droplet does not adhere to it, but quickly shrinks into a hemispherical shape and rolls down. As the droplet shrinks and slides down, the contact area between the droplet and the polytetrafluoroethylene film decreases. At this time, the metal electrode layer 422 below the polytetrafluoroethylene film loses electrons to the ground, thereby inducing positive charge to achieve electrostatic balance (see Figure 5 c1 and d1 in the figure). The process of the metal electrode layer 422 losing electrons produces the following Figure 6 and Figure 7 Negative current signal in.

[0080] As an electret material, polytetrafluoroethylene has good charge storage capacity, that is, after the first drop of liquid falls on the surface of the polytetrafluoroethylene film, the negative charge on the surface of the polytetrafluoroethylene film will be retained on it. When subsequent droplets rub against the polytetrafluoroethylene film, for example, when the nth drop of liquid falls on the surface of the polytetrafluoroethylene film (see Figure 5 Where a2 and n are natural numbers greater than or equal to 2). Since the droplets carry some positive and negative charges before they fall, when the droplets spread, the positive charges in the droplets form an electrostatic balance with the negative charges stored on the surface of the polytetrafluoroethylene film (see Figure 5b2 in the figure), during this process the metal electrode layer 422 will obtain electrons from the earth to neutralize the positive charge on its surface. In this process, Figure 6 and Figure 7 Then, as the droplet shrinks and slides down, the contact area between the droplet and the polytetrafluoroethylene film decreases. At this time, the metal electrode layer 422 under the polytetrafluoroethylene film will lose electrons to the ground again, thereby inducing positive charge to achieve electrostatic balance (see Figure 5 c2 and d2 in ).

[0081] In this way, as the droplets continue to repeat the process of spreading and contracting, the raindrop friction power generation plate 42 generates an alternating current under the action of the droplets.

[0082] In some embodiments, as Figure 3 As shown, the outdoor unit further includes: a control component 6; the control component 6 includes a power controller and a battery;

[0083] The solar cell panel 41 and the raindrop friction power generation panel 42 are electrically connected to the power controller respectively, and the power controller is electrically connected to the battery and the wind transmission component respectively.

[0084] It is understood that the power controller includes a rectifier bridge and a voltage conversion circuit. For example, the rectifier bridge converts the AC power output by the raindrop triboelectric generator 42 into DC power, and the voltage conversion circuit steps up or down the DC power output by the rectifier bridge to ensure that the voltage output by the voltage conversion circuit is compatible with the charging voltage of the battery. Of course, the voltage output by the solar panel 41 can also be stored in the battery after being stepped up or down by the voltage conversion circuit.

[0085] When the outdoor unit is in use or not in use, the battery can be used to store the electricity generated by the raindrop friction power generation plate 42 and / or the solar panel 41. The battery can provide a stable operating voltage to the air supply component to meet the operating requirements of the air supply component when the outdoor unit is not in use.

[0086] In some embodiments, as Figure 2 、 Figure 8 and Figure 11 As shown, the air delivery component includes an air inlet module 2 and an air outlet module 3; the air inlet module 2 and the air inlet 121 are arranged opposite to each other, and the air outlet module 3 and the air outlet 122 are arranged opposite to each other;

[0087] The air inlet module 2 is used to drive the air into the compartment from the air inlet 121 , and the air outlet module 3 is used to drive the air in the compartment to be discharged from the air outlet 122 .

[0088] It is understandable that both the air inlet module 2 and the air outlet module 3 can adopt axial flow fans, the air inlet module 2 is used to supply air toward the interior of the compartment, and the air outlet module 3 is used to draw air toward the exterior of the compartment. The air inlet module 2 and the air outlet module 3 cooperate with each other to enhance the efficiency of air exchange between the compartment and the external environment.

[0089] In the hot summer, the temperature in the compartment of the cabinet 1 will gradually rise. In order to prevent the high temperature from affecting the normal operation of the components installed in the compartment, the air inlet module 2 and the air outlet module 3 can be controlled to start working respectively. At this time, the air inlet module 2 drives the air with a relatively low external temperature to enter the compartment of the cabinet 1 from the air inlet 121, and then the air outlet module 3 drives the air in the compartment to be discharged from the air outlet 122, so as to perform convection heat dissipation on the components in the compartment based on the flow of airflow.

[0090] In some embodiments, as Figure 9 As shown, the heat exchange device further includes a heating element 5, which is provided in the air inlet module 2 to heat the air delivered by the air inlet module 2;

[0091] like Figure 1 and Figure 2 As shown, the air inlet 121 is arranged on the lower side of the cabinet 1, and the air outlet 122 is arranged on the upper side of the cabinet 1; the air inlet module 2 is used to drive the air to flow from bottom to top in the compartment, so that the air heated by the heating element 5 circulates in the compartment.

[0092] It can be understood that by configuring the air outlet 122 and the air inlet 121 to be arranged relative to each other up and down, when heating the internal environment of the compartment, only the air inlet module 2 and the heating element 5 are started, and the air inlet module 2 drives the air to flow from bottom to top in the compartment, and the heating element 5 is used to heat the air output by the air inlet module 2. When the hot air reaches the position where the air outlet module 3 is located, the hot air will automatically flow to the lower side of the compartment and circulate in the compartment, thereby ensuring the heating effect of the internal environment of the compartment.

[0093] In some embodiments, as Figure 2 and Figure 8 As shown, the air intake module 2 includes an air intake cover 21, a first air delivery component 22 and a first damper component 23; the air intake cover 21 has an air intake cavity and a first cover opening, a first vent and a second vent connected to the air intake cavity, the first cover opening is connected to the cabinet 1, and is covered on the air intake 121; the first air delivery component 22 is arranged at the first vent; the first damper component 23 is arranged at the second vent to control the opening and closing state of the second vent.

[0094] It is understandable that in the hot summer, when the indoor environment needs to be cooled, the first damper assembly 23 controls the second vent to be in a closed state. Then, when the first air delivery assembly 22 starts working, the first air delivery assembly 22 can be used to drive the outside cold air into the air inlet cavity from the air inlet 121, and then into the interior through the first vent.

[0095] In cold winter, when the indoor environment needs to be heated, the first damper assembly 23 controls the second vent to be in an open state. When the heating element 5 is turned on, the first air delivery assembly 22 can also be used to drive the indoor air from the second vent to the air inlet chamber, and then return to the indoor through the first vent, so as to promote air flow in the indoor and ensure that the temperature in the indoor is quickly increased.

[0096] The air inlet cover 21 may be configured with a plurality of first vents, and a plurality of first air delivery components 22 are provided, and the plurality of first air delivery components 22 are installed at the plurality of first vents in a one-to-one correspondence.

[0097] In some embodiments, as Figure 9 As shown, the first air delivery component 22 includes a first fan 221 and a wind tube 222; the first fan 221 is arranged at the first vent and is arranged opposite to the first end of the wind tube 222; the wind tube 222 is arranged on the air inlet cover 21, and the second end of the wind tube 222 is provided with a heating element 5.

[0098] It is understandable that the air duct 222 is vertically distributed, the first fan 221 is arranged at the lower end of the air duct 222, and the heating element 5 is arranged at the upper end of the air duct 222.

[0099] By arranging the heating element 5 at the second end of the air duct 222, this design realizes the integrated design of the first air delivery component 22 and the heating element 5. In actual operation, the first fan 221 drives the air in the air inlet cover 21 into the air duct 222, and then heats the air through the heating element 5 and delivers it to the room, thereby delivering hot air to the room to heat the environment in the room.

[0100] Optionally, the heating element 5 can be configured in a grid shape. This design does not affect the normal air outlet of the air duct 222, but also increases the contact area with the air, thereby improving the heating effect on the air outlet of the air duct 222.

[0101] Optionally, to ensure the air supply effect, the first fan 221 may be an axial flow fan, which is built into the first ventilation port.

[0102] Optionally, the heating element 5 may be connected to the second end of the wind tube 222 via a heat insulating member to prevent the heat generated by the heating element 5 from being conducted to the wind tube 222 .

[0103] In some embodiments, as Figure 8 As shown, the air inlet cover 21 has a first side wall 2101 and a second side wall 2102; the first side wall 2101 is used to be connected to the inner wall of the cabinet 1, and the second side wall 2102 is opposite to the first side wall 2101 and is arranged at an angle; the first cover opening is provided on the first side wall 2101, and the second ventilation opening is provided on the second side wall 2102; wherein, when the first damper assembly 23 closes the second ventilation opening, the second side wall 2102 and at least part of the first damper assembly 23 are used to drain rainwater entering the air inlet cavity to the air inlet 121, and discharge it from the air inlet 121.

[0104] It can be understood that the air inlet cover 21 has a top wall, a first side wall 2101 and a second side wall 2102. The top wall is horizontally arranged and located on the upper side of the first side wall 2101 and the second side wall 2102. The first air delivery component 22 is installed at the first vent located on the top wall.

[0105] Since the first side wall 2101 is connected to the inner wall of the cabinet 1, the inner wall of the cabinet 1 is generally vertical, and the first side wall 2101 is also configured to be vertical. Since the second side wall 2102 is inclined relative to the first side wall 2101, the second side wall 2102 is inclined relative to the vertical plane. The lower end of the second side wall 2102 and the lower end of the first side wall 2101 can be configured to intersect.

[0106] In actual application, when rainwater from the outside splashes into the air inlet cover 21 from the air inlet 121, most of the rainwater will adhere to the second side wall 2102. The second side wall 2102 will guide the rainwater to flow downward until the rainwater is discharged from the air inlet 121, thereby preventing rainwater from entering the cabinet 1.

[0107] The second side wall 2102 is arranged at an acute angle relative to the first side wall 2101 so as to better control rainwater from flowing downward toward the air inlet 121 .

[0108] In some embodiments, as Figure 8 、 Figure 10 and Figure 11 As shown, the first damper assembly 23 includes a driving motor 231, a linkage assembly 232 and a first damper 233;

[0109] The first damper 233 is rotatably provided at the second vent, and the driving motor 231 is connected to the first damper 233 via the linkage assembly 232 to control the first damper 233 to switch between the first state and the second state;

[0110] When the first damper 233 is in the first state, the first damper 233 is in a position to close the second vent, and the air inlet 121 is connected to the first vent through the air inlet cavity;

[0111] When the first damper 233 is in the second state, the first damper 233 is located in the air inlet cavity and is in a position to close the air inlet 121, and the second vent is connected to the first vent through the air inlet cavity.

[0112] It is understandable that the drive motor 231 can be a stepper motor, and the linkage assembly 232 includes a connecting rod and a slide rail. The output end of the drive motor 231 is connected to the first end of the connecting rod, and the second end of the connecting rod is movably provided on the slide rail along the extension direction of the slide rail; the slide rail is connected to the first damper 233.

[0113] The lower end of the first damper 233 is rotatably connected to the lower side of the second vent, the drive motor 231 is disposed outside the air inlet cavity, and the slide rail is disposed on a side of the first damper 233 facing the drive motor 231 .

[0114] A sliding contact can be provided at the second end of the connecting rod. The slide rail is provided with a guide groove extending along the extension direction of the slide rail. The sliding contact is provided in the guide groove and can move in the guide groove along the extension direction of the slide rail.

[0115] like Figure 8 and Figure 10 As shown, when the internal environment of the compartment is cooled, the driving motor 231 drives the connecting rod to rotate along the first rotation direction, the connecting rod pulls the slide rail toward the side close to the second vent, the second end of the connecting rod moves toward the first end of the slide rail, and the first damper 233 is flipped toward the side close to the second vent under the drive of the slide rail until the first damper 233 covers the second vent. At this time, the first damper 233 is in the first state.

[0116] Since the second vent is closed, when the first air delivery component 22 is started, the outside cold air first enters the air inlet cavity from the air inlet 121, and then enters the room through the first vent. Figure 10 Arrows are used to indicate the direction of air flow.

[0117] like Figure 8 and Figure 11 As shown, when the internal environment of the compartment is heated, the driving motor 231 drives the connecting rod to rotate along the second rotation direction, the connecting rod pushes the slide rail toward the side away from the second vent, and the second end of the connecting rod moves toward the second end of the slide rail. Driven by the slide rail, the first damper 233 flips toward the side close to the air inlet 121 until the end of the first damper 233 away from the second vent contacts the inner wall of the cabinet 1, thereby separating the air inlet cavity into a first cavity and a second cavity. At this time, the first damper 233 is in the second state, the second vent is connected to the first vent through the first cavity, and the air inlet 121 is connected to the second cavity and isolated from the first cavity, that is, the air inlet 121 is in a closed state.

[0118] Since the air inlet 121 is closed, when the first air delivery component 22 is activated, the air in the compartment first enters the air inlet cavity from the second vent, and then returns to the compartment from the first vent. At this time, by activating the heating element 5, the air output from the first air delivery component 22 can be heated, and the hot air can be used to heat the internal environment of the compartment. Figure 11 Arrows are used to indicate the direction of air flow.

[0119] In some embodiments, as Figure 2 and Figure 12 As shown, the air outlet module 3 includes an air outlet cover 31, a second air delivery component 32 and a second air door component 33;

[0120] The air outlet cover 31 has an air outlet cavity and a second cover opening and a third ventilation opening connected to the air outlet cavity. The second cover opening is connected to the cabinet 1 and covers the air outlet 122; the second air delivery component 32 is arranged at the third ventilation opening; the second air door component 33 is arranged in the air outlet cavity to control the opening and closing state of the air outlet 122.

[0121] It is understandable that the air outlet cover 31 can adopt the same structure as the air inlet cover 21 to prevent rainwater from the outside from entering the cabinet 1 through the air outlet 122.

[0122] When the environment in the compartment is cooled, the second damper assembly 33 controls the air outlet 122 to open, so that the second air delivery assembly 32 drives the air in the compartment into the air outlet cavity and then is discharged from the air outlet 122 .

[0123] When heating the environment in the compartment, the second damper assembly 33 controls the air outlet 122 to be closed. At this time, the second air delivery assembly 32 can be configured to be in a working state or in a stopped state, as long as it does not affect the normal flow of the hot air heated by the heating element 5 in the compartment.

[0124] The air outlet cover 31 can be configured with multiple third vents, and multiple second air delivery components 32 are provided, and the multiple second air delivery components 32 are installed at the multiple third vents in a one-to-one correspondence. Among them, each second air delivery component 32 can use an axial flow fan.

[0125] In some embodiments, as Figure 12 As shown, the second damper assembly 33 includes a driving member 331 and a second damper 332; the second damper 332 is rotatably disposed in the air outlet cover 31, and the driving member 331 and the second damper 332 are transmission-connected to control the second damper 332 to rotate between a first position and a second position;

[0126] When the second damper 332 is in the first position, the air outlet 122 can be connected to the third vent through the air outlet cavity; when the second damper 332 is in the second position, the second damper 332 is used to block the connection between the air outlet 122 and the third vent.

[0127] It is understandable that the driving member 331 can be a telescopic rod, a rotary motor, etc., to drive the second damper 332 to rotate in the air outlet cover 31, thereby changing the fluid communication state between the air outlet 122 and the third vent.

[0128] like Figure 13 As shown, when the second damper 332 is in the first position, fluid communication is formed between the air outlet 122 and the third vent. In this way, when the second air delivery component 32 is started, the second air delivery component 32 can drive the air in the compartment into the air outlet cavity and then be discharged from the air outlet 122. Figure 13 Arrows are used to indicate the direction of air flow.

[0129] like Figure 14 As shown, when the second damper 332 is in the second position, the second damper 332 divides the air outlet cavity into a third cavity and a fourth cavity. At this time, the third vent is connected to the third vent, and the air outlet 122 is connected to the fourth cavity. Since the third cavity and the fourth cavity are isolated from each other, the fluid communication between the air outlet 122 and the third vent is blocked by the second damper 332. In this case, if the second air supply component 32 is not started, the air in the room that is transported from bottom to top to the air outlet module 3 will flow back downward under the action of its own weight. Figure 14 Arrows are used to indicate the direction of air flow.

[0130] In some embodiments, as Figure 12 As shown, the driving member 331 includes an electromagnet, which is disposed in the air outlet cover 31 and is located on one side of the second air door 332;

[0131] When the electromagnet is powered on, the electromagnet and the second damper 332 are attracted to each other, so that the second damper 332 is in the first position; when the electromagnet is powered off, the electromagnet and the second damper 332 are separated, and the second damper 332 rotates to the second position under the action of gravity.

[0132] It is understandable that the electromagnet can be configured to be installed on the inner wall of the air outlet cover 31, with the magnetic end of the electromagnet extending toward the second air door 332 made of ferromagnetic material, and the electromagnet can be configured to be connected to the control module shown in the above embodiment.

[0133] When the internal environment of the compartment needs to be cooled, the electromagnet can be energized. Under the magnetic force of the electromagnet, the second damper 332 will flip upward until the air outlet 122 can be connected to the third vent through the air outlet cavity.

[0134] When the internal environment of the compartment needs to be heated, the electromagnet can be controlled to be de-energized. Since the electromagnet no longer generates magnetic force on the second damper 332, the second damper 332 automatically flips downward under the action of its own gravity until the connection between the air outlet 122 and the third vent is blocked.

[0135] It should be pointed out here that when the outdoor unit is in a non-working state, the internal environment of the cabinet 1 can be isolated from the outside world by controlling the air inlet 121 and the air outlet 122 to be closed respectively, so as to prevent external water vapor from entering the cabinet 1 through the air inlet 121 or the air outlet 122, thereby avoiding affecting the service life and safety of the components inside the cabinet 1.

[0136] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
