Description

Technical Field

[0001] The present application relates to the technical field of air conditioning, and in particular to an indoor unit and an air conditioner. Background Art

[0002] The indoor unit uses a heat exchanger to adjust the temperature of the air entering the inlet and then sends it out through the outlet. This air radiates heat with the surrounding air, thereby regulating the temperature of the entire space. Existing indoor units all use a single air intake and outlet method, with air entering from the top and exiting from the bottom. This causes a certain temperature difference in the vertical direction of the space, with warmer air distributed at the top of the room, while cooler air, due to its greater density, is distributed at the bottom. In heating mode, the warmer air at the top of the room is repeatedly drawn into the indoor unit, while the cooler air below relies solely on heat radiation for heat exchange, resulting in energy waste and increased energy consumption. Utility Model Content

[0044] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0045] The disclosure below provides many different embodiments or examples for implementing different structures of the embodiments of the present application. In order to simplify the disclosure of the embodiments of the present application, the components and settings of specific examples are described below. Of course, they are merely examples and are not intended to limit the embodiments of the present application. In addition, the embodiments of the present application may repeat reference numbers and / or letters in different examples. This repetition is for the purpose of simplicity and clarity and does not itself indicate the relationship between the various embodiments and / or settings discussed.

[0046] For ease of description, spatially relative terms may be used herein to describe the relative position or movement of one element or feature relative to another element or feature as shown in the figures, such as "inside," "outside," "inside," "outside," "below," "beneath," "above," "above," "front," "back," and the like. Such spatially relative terms are intended to include different orientations of the device in use or operation other than the orientation depicted in the figures. For example, if the device in the figures undergoes a positional flip or a change in posture or a change in motion, then these directional indications will also change accordingly. For example, an element described as "below" or "below" another element or feature will subsequently be oriented as "above" or "above" another element or feature. Thus, the example term "below" can include both above and below orientations. The device may be oriented otherwise (rotated 90 degrees or in other orientations) and the spatially relative descriptors used herein will be interpreted accordingly.

[0047] In order to solve the problems in the prior art, the present application provides an indoor unit and an air conditioner, which can adjust the position of the air inlet and outlet to avoid the situation where high-temperature gas is repeatedly sucked into the indoor unit when running in heating mode, thereby reducing energy waste and lowering energy consumption.

[0052] like Figure 1-16 As shown, an embodiment of the present application provides an indoor unit, including: a shell 1, an adjustment mechanism 2, a fan assembly 3 and a heat exchange assembly 4.

[0053] A first air inlet 11 and a first air outlet 12 are provided at the top of the housing 1 , and a second air inlet 13 and a second air outlet 14 are provided at the bottom of the housing 1 .

[0054] The regulating mechanism 2 is provided on the housing 1 , and is used to control the opening and closing of the first air inlet 11 , the first air outlet 12 , the second air inlet 13 and the second air outlet 14 .

[0055] The fan assembly 3 is disposed in the housing 1 .

[0056] The heat exchange component 4 is disposed in the shell 1 and exchanges heat with the gas entering the shell 1 .

[0057] Among them, when the first air inlet 11 and the second air outlet 14 are opened, and the second air inlet 13 and the first air outlet 12 are closed, the fan assembly 3 drives the external air into the shell 1 through the first air inlet 11 and sends it out through the second air outlet 14; when the second air inlet 13 and the first air outlet 12 are opened, and the first air inlet 11 and the second air outlet 14 are closed, the fan assembly 3 drives the external air into the shell 1 through the second air inlet 13 and sends it out through the first air outlet 12.

[0058] In the present application, the opening and closing states of the first air inlet 11, the first air outlet 12, the second air inlet 13 and the second air outlet 14 are controlled by the regulating mechanism 2, so that the position of the air inlet and outlet of the indoor unit can be adjusted. In the heating mode, by opening the second air inlet 13 and the first air outlet 12, and closing the first air inlet 11 and the second air outlet 14, the fan assembly 3 allows the external air to enter the shell 1 through the second air inlet 13 at the bottom of the shell 1 and exchange heat with the heat exchange assembly 4, and then send it out through the first air outlet 12 at the top of the shell 1, which can effectively avoid the situation where the high-temperature gas is repeatedly sucked into the shell 1, reduce energy waste, and reduce energy consumption.

[0059] In the related art, the existing indoor unit's air supply method is relatively simple, namely, air intake from the top and air outlet from the bottom. Due to the following characteristics of the vertical distribution of air: the higher-temperature gas is mainly distributed in the upper part of the room due to its lower density, while the lower-temperature gas is mainly distributed in the lower part of the room due to its higher density. When the air conditioner is operating in cooling mode, the gas with higher temperature at the top enters through the air inlet at the top of the indoor unit and is discharged through the air outlet at the bottom of the indoor unit after heat exchange. The temperature at the air inlet is higher, and the temperature at the air outlet is lower after heat exchange. It radiates with the temperature of the surrounding environment and can effectively exchange heat with the surrounding environment. However, when the air conditioner is operating in heating mode, the higher-temperature gas at the top enters through the air inlet at the top of the indoor unit and is discharged through the air outlet at the bottom of the indoor unit after heat exchange. The temperature at the air inlet is higher, causing the higher-temperature gas to be repeatedly drawn into the indoor unit, while the lower-temperature airflow remains in the lower area of the room and does not participate in direct heat exchange. It only slowly heats up by heat radiation, resulting in energy waste, high energy consumption, and low heat exchange efficiency. Moreover, the existing air supply mode with upper air inlet and lower air outlet blows hot air directly onto the user, affecting the user's comfort.

[0060] In the embodiment of the present application, when the air conditioner is operating in cooling mode, the first air inlet 11 and the second air outlet 14 are opened, and the first air outlet 12 and the second air inlet 13 are closed. Under the action of the fan assembly 3, air enters the housing 1 through the first air inlet 11 at the top of the housing 1 and is discharged through the second air outlet 14 at the bottom of the housing 1 after heat exchange. Like existing air conditioners, high-temperature air can be sucked into the indoor unit for heat exchange into low-temperature air before being discharged. When the air conditioner is operating in heating mode, the first air inlet 11 and the second air outlet 14 are closed, and the first air outlet 12 and the second air inlet 13 are opened. Under the action of the fan assembly 3, air enters the housing 1 through the second air inlet 13 at the bottom of the housing 1 and is discharged through the first air outlet 12 at the top of the housing 1 after heat exchange, achieving downward air intake and upward air discharge, preventing the high-temperature air at the top of the room from being repeatedly sucked into the housing 1, and preventing the airflow after heat exchange from being repeatedly sucked into the interior of the housing 1, ensuring that the low-temperature air in the lower area of the room is preferentially heat exchanged, achieving high heat exchange efficiency, reducing energy waste, lowering energy consumption, and improving heat exchange efficiency. Moreover, the present application adopts the form of lower air inlet and upper air outlet, which can avoid direct blowing of hot air and improve user comfort.

[0061] Specifically, the regulating mechanism 2 in the present application can be designed as an integral part, that is, when the regulating mechanism 2 opens the first air inlet 11, the first air outlet 12 and the second air inlet 13 are closed synchronously, and the second air outlet 14 is opened synchronously; when the regulating mechanism 2 closes the first air inlet 11, the second air inlet 13 and the first air outlet 12 are opened synchronously, and the second air outlet 14 is closed synchronously.

[0062] Optionally, the regulating mechanism 2 in the present application can also adopt a split design, and the regulating mechanism 2 includes a first unit and a second unit. The first unit is used to control the first air inlet 11 and the first air outlet 12. When the first unit opens the first air inlet 11, the first air outlet 12 is closed synchronously. When the first unit closes the first air inlet 11, the first air outlet 12 is opened synchronously. The second unit is used to control the second air inlet 13 and the second air outlet 14. When the second unit opens the second air inlet 13, the second air outlet 14 is closed synchronously. When the second unit closes the second air inlet 13, the second air outlet 14 is opened synchronously.

[0063] Optionally, the regulating mechanism 2 in the present application can also adopt a split design, and the regulating mechanism 2 includes a first unit and a second unit. The first unit is used to control the first air inlet 11 and the second air inlet 13. When the first unit opens the first air inlet 11, the second air inlet 13 is closed synchronously. When the first unit closes the first air inlet 11, the second air inlet 13 is opened synchronously. The second unit is used to control the first air outlet 12 and the second air outlet 14. When the second unit opens the first air outlet 12, the second air outlet 14 is closed synchronously. When the second unit closes the first air outlet 12, the second air outlet 14 is opened synchronously.

[0064] Optionally, the regulating mechanism 2 in the present application may also adopt a split design, comprising four units, each of which independently controls the opening and closing of the first air inlet 11, the first air outlet 12, the second air inlet 13, and the second air outlet 14. The opening and closing states of the first air inlet 11, the first air outlet 12, the second air inlet 13, and the second air outlet 14 are controlled as needed. That is, when the air conditioner is operating in cooling mode, the first air inlet 11 and the second air outlet 14 are opened, and the second air outlet 14 and the second air inlet 13 are closed; when the air conditioner is operating in cooling mode, the second air inlet 13 and the first air outlet 12 are opened, and the first air inlet 11 and the second air outlet 14 are closed.

[0065] like Figure 16 As shown, in some embodiments, the fan assembly 3 includes a crossflow blade 31 and a driving member 32 for driving the crossflow blade 31 to rotate, the air inlet direction and the air outlet direction of the crossflow blade 31 are respectively arranged along the radial direction of the crossflow blade 31, and the first air inlet 11, the first air outlet 12, the second air inlet 13 and the second air outlet 14 are arranged along the circumference of the shell 1.

[0066] In the present application, the crossflow blades 31 are arranged along the extension direction of the inner cavity of the shell 1. In the case of a wall-mounted indoor unit, the crossflow blades 31 are arranged horizontally. When the crossflow blades 31 rotate, they drive the gas in the shell 1 to flow radially along the crossflow blades 31, so that the air flow direction entering the crossflow blades 31 and the air flow direction out of the crossflow blades 31 are both arranged radially along the crossflow blades 31. By arranging the first air inlet 11, the first air outlet 12, the second air inlet 13 and the second air outlet 14 along the circumference of the shell 1, there is no need to change the rotation direction of the crossflow blades 31, and at the same time, there is no need to set an air guide plate that can change the direction of the airflow in the shell 1, so that the indoor unit can be switched between the upper air inlet and lower air outlet mode and the lower air inlet and upper air outlet mode. The structure is simple and ensures the smooth operation of the air supply mode.

[0067] Specifically, the driving member 32 is a motor, which is fixed in the housing 1. The output end of the motor is connected to one end of the crossflow blade 31. A blade shaft sleeve is provided at the end of the crossflow blade 31 away from the motor to ensure the stability of the rotation of the crossflow blade 31 and thus ensure the stability of the air supply.

[0068] like Figure 5 and 7 As shown, in some embodiments, the indoor unit is a wall-mounted indoor unit. When the indoor unit is installed on the wall, the first air outlet 12 is located on the side of the first air inlet 11 away from the wall, and the second air outlet 14 is located on the side of the second air inlet 13 away from the wall.

[0069] In the present application, the first air outlet 12 and the first air inlet 11 are both arranged at the top of the shell 1, and the first air outlet 12 is located on the side of the first air inlet 11 away from the wall, that is, the first air outlet 12 is located in front of the first air inlet 11, the second air outlet 14 and the second air inlet 13 are both arranged at the bottom of the shell 1, and the second air outlet 14 is located on the side of the second air inlet 13 away from the wall, that is, the second air outlet 14 is located in front of the second air inlet 13, and the cross flow fan blade 31 is inside the shell 1. When rotating, the air flow in the shell 1 is driven to rotate. When the first air inlet 11 and the second air outlet 14 are opened, and the second air inlet 13 and the first air outlet 12 are closed, the external air is driven to enter the shell 1 through the first air inlet 11 and be sent out through the second air outlet 14; when the second air inlet 13 and the first air outlet 12 are opened, and the first air inlet 11 and the second air outlet 14 are closed, the external air is driven to enter the shell 1 through the second air inlet 13 and be sent out through the first air outlet 12.

[0070] Specifically, wind guide plates are generally provided at the first air outlet 12 and the second air outlet 14. Under the action of the wind guide plates, the first air outlet 12 and the second air outlet 14 can only be used to discharge air, and the gas will not enter the shell 1 from the first air outlet 12 and the second air outlet 14.

[0071] like Figure 1 As shown, in some embodiments, the adjustment mechanism 2 includes: a first baffle assembly 21, arranged at the first air inlet 11 of the shell 1, for controlling the opening and closing of the first air inlet 11; a second baffle assembly 22, arranged at the second air inlet 13 of the shell 1, for controlling the opening and closing of the second air inlet 13; a first air guide assembly 23, arranged at the first air outlet 12 of the shell 1, for controlling the opening and closing of the first air outlet 12; and a second air guide assembly 24, arranged at the second air outlet 14 of the shell 1, for controlling the opening and closing of the second air outlet 14.

[0072] In the present application, the opening and closing of the first air inlet 11 is controlled by the first baffle assembly 21, the opening and closing of the second air inlet 13 is controlled by the second baffle assembly 22, the opening and closing of the first air outlet 12 is controlled by the first air guide assembly 23, and the opening and closing of the second air outlet 14 is controlled by the second air guide assembly 24. The opening and closing of the first air inlet 11, the first air outlet 12, the second air inlet 13 and the second air outlet 14 can be controlled separately according to actual needs. The structure is simple and there is no need to set up too many transmission structures, thereby ensuring the accuracy of controlling the first air inlet 11, the first air outlet 12, the second air inlet 13 and the second air outlet 14.

[0073] In an optional embodiment, the adjustment mechanism can also adopt an integrated design, that is, a power source controls the first air inlet 11, the first air outlet 12, the second air inlet 13 and the second air outlet 14 respectively through a transmission structure. When the first air inlet 11 is opened, the first air outlet 12 and the second air inlet 13 are closed synchronously, and the second air outlet 14 is opened synchronously; when the first air inlet 11 is closed, the first air outlet 12 and the second air inlet 13 are opened synchronously, and the second air outlet 14 is closed synchronously.

[0074] In another optional embodiment, the regulating mechanism may also adopt a split design, comprising two power sources, one of which controls two of the first air inlet 11, the first air outlet 12, the second air inlet 13, and the second air outlet 14, and the other controls the other two of the first air inlet 11, the first air outlet 12, the second air inlet 13, and the second air outlet 14. Alternatively, one power source may control one of the first air inlet 11, the first air outlet 12, the second air inlet 13, and the second air outlet 14, and the other may control the other three of the first air inlet 11, the first air outlet 12, the second air inlet 13, and the second air outlet 14.

[0075] In another optional embodiment, the adjustment mechanism can also adopt a split design, and the adjustment mechanism includes three power sources, two of which control two of the first air inlet 11, the first air outlet 12, the second air inlet 13 and the second air outlet 14 respectively, and the other power source controls the other two of the first air inlet 11, the first air outlet 12, the second air inlet 13 and the second air outlet 14.

[0076] like Figure 1 As shown, in some embodiments, the first air guide assembly 23 includes: a first air guide plate 231, movably arranged at the first air outlet 12, the first air guide plate 231 includes a first state of covering the first air outlet 12 and a second state of opening the first air outlet 12; and a first driving unit 232, arranged on the shell 1, the output end of the first driving unit 232 is connected to the first air guide plate 231, and is used to drive the first air guide plate 231 to switch between the first state and the second state.

[0077] In the present application, the first air guide plate 231 can be rotatably arranged at the first air outlet 12, and the first driving unit 232 is a driving motor. The first driving unit 232 is used to drive the first air guide plate 231 to rotate between the first state and the second state, thereby realizing the opening and closing of the first air outlet 12.

[0078] like Figure 7 As shown, further, when the first air guide plate 231 is in the second state, the first driving unit 232 can adjust the angle of the first air guide plate 231 to adjust the air outlet direction at the first air outlet 12.

[0079] In the present application, the first driving unit 232 can also adjust the angle of the first air guide plate 231, thereby adjusting the air outlet direction at the first air outlet 12, so that the air supply direction of the first air outlet 12 can be diagonally upward, horizontally, or diagonally downward. By adjusting the air supply direction, the air supply direction can be selected according to the specific installation height of the indoor unit and the area in the room that needs to be temperature controlled. For example, if the installation height of the indoor unit is low and the upper area of the room needs to be heated, diagonally upward air supply can be selected at this time, so that the hot air can more fully fill the upper area of the room, and the low-temperature gas in the lower area of the room can be continuously sucked into the indoor unit, avoiding the situation where the hot air is repeatedly sucked into the indoor unit, thereby reducing energy consumption.

[0080] like Figure 1 As shown, in some embodiments, the second air guide assembly 24 includes: a second air guide plate 241, movably arranged at the second air outlet 14, the second air guide plate 241 includes a third state of covering the second air outlet 14 and a fourth state of opening the second air outlet 14; and a second driving unit 242, arranged on the shell 1, the output end of the second driving unit 242 is connected to the second air guide plate 241, and is used to drive the second air guide plate 241 to switch between the third state and the fourth state.

[0081] In this application, the second air guide plate 241 can be rotatably arranged at the second air outlet 14, and the second driving unit 242 is a driving motor. The second driving unit 242 is used to drive the second air guide plate 241 to rotate between the third state and the fourth state, thereby realizing the opening and closing of the second air outlet 14.

[0082] like Figure 5 As shown, further, when the second air guide plate 241 is in the fourth state, the second driving unit 242 can adjust the angle of the second air guide plate 241 to adjust the air outlet direction at the second air outlet 14.

[0083] In the present application, the second driving unit 242 can also adjust the angle of the second air guide plate 241, thereby adjusting the air outlet direction at the second air outlet 14, so that the air supply direction of the second air outlet 14 can be diagonally upward, horizontally, or diagonally downward. By adjusting the air supply direction, the air supply direction can be selected according to the specific installation height of the indoor unit and the area in the room that needs to be temperature controlled. For example, if the installation height of the indoor unit is low and the upper area of the room needs to be heated, diagonally upward air supply can be selected at this time, so that the hot air can more fully fill the upper area of the room, and the low-temperature gas in the lower area of the room can be continuously drawn into the indoor unit, avoiding the situation where the hot air is repeatedly drawn into the indoor unit, thereby reducing energy consumption.

[0084] like Figure 5-6 As shown, in some embodiments, the first baffle assembly 21 includes: a first baffle 211 and a third driving unit 212 .

[0085] The first baffle 211 is slidably arranged on the shell 1, and a first connecting port 2111 is arranged on the first baffle 211. The first baffle 211 includes a fifth state and a sixth state. When the first baffle 211 is in the fifth state, the first connecting port 2111 is connected to the first air inlet 11 to open the first air inlet 11; when the first baffle 211 is in the sixth state, the first connecting port 2111 is staggered with the first air inlet 11 to close the first air inlet 11.

[0086] The third driving unit 212 is disposed on the housing 1 , and an output end of the third driving unit 212 is connected to the first baffle 211 for driving the first baffle 211 to switch between the fifth state and the sixth state.

[0087] In this application, the third driving unit 212 drives the first baffle 211 to slide, so that the first baffle 211 switches between the fifth state and the sixth state. When the first baffle 211 slides to the fifth state, the first connecting hole is connected to the first air inlet 11, and the first air inlet 11 is in the open state; when the first baffle 211 slides to the sixth state, the first connecting hole and the first air inlet 11 are staggered, so that the first air inlet 11 is in the closed state, thereby realizing the control of the opening and closing of the first air inlet 11.

[0088] Specifically, the third drive unit 212 includes a first stepper motor 2121, a first ratchet 2122 disposed at the output end of the first stepper motor 2121, and a first rack 2123 connected to the first baffle 211. The first rack 2123 extends along the sliding direction of the first baffle 211. The first stepper motor 2121 drives the first ratchet 2122 to rotate, which in turn drives the first rack 2123 to move, thereby allowing the first rack 2123 to slide the first baffle 211. A guide rail is disposed within the housing 1, which limits the first baffle 211 so that it can only slide along the extension direction of the guide rail, ensuring the sliding stability and positional accuracy of the first baffle 211, thereby ensuring the precision with which the first baffle 211 controls the first air inlet 11.

[0089] like Figure 2-3 As shown, in some embodiments, the second baffle assembly 22 includes: a second baffle 221, which is slidably set on the shell 1, and a second connecting port 2211 is set on the second baffle 221, and the second baffle 221 includes a seventh state and an eighth state. When the second baffle 221 is in the seventh state, the second connecting port 2211 is connected to the second air inlet 13 to open the second air inlet 13; when the second baffle 221 is in the eighth state, the second connecting port 2211 is staggered with the second air inlet 13 to close the second air inlet 13; and a fourth drive unit 222, which is set on the shell 1, and the output end of the fourth drive unit 222 is connected to the second baffle 221, for driving the second baffle 221 to switch between the seventh state and the eighth state.

[0090] In this application, the third driving unit 212 drives the second baffle 221 to slide, so that the second baffle 221 switches between the seventh state and the eighth state. When the second baffle 221 slides to the seventh state, the second connecting hole is connected to the second air inlet 13, and the second air inlet 13 is in the open state; when the second baffle 221 slides to the eighth state, the second connecting hole and the second air inlet 13 are staggered, so that the second air inlet 13 is in the closed state, thereby realizing the control of the opening and closing of the second air inlet 13.

[0091] Specifically, the fourth drive unit 222 includes a second stepper motor 2221, a second ratchet 2222 disposed at the output end of the second stepper motor 2221, and a second rack 2223 connected to the second baffle 221. The second rack 2223 extends along the sliding direction of the second baffle 221. The second stepper motor 2221 drives the second ratchet 2222 to rotate, which in turn drives the second rack 2223 to move, thereby allowing the second rack 2223 to slide the second baffle 221. A guide rail is disposed within the housing 1, which limits the second baffle 221 so that it can only slide along the extension direction of the guide rail, ensuring the sliding stability and position accuracy of the second baffle 221, thereby ensuring the accuracy of the second baffle 221's control over the second air inlet 13.

[0092] In some embodiments, a maintenance port is provided on a side of the housing 1 away from the wall, and a detachable panel 15 is provided at the maintenance port; the fan assembly 3 is provided between the heat exchange assembly 4 and the maintenance port.

[0093] In this application, when performing daily cleaning and maintenance on the heat exchange component 4 and the fan component 3 inside the shell 1, it is only necessary to remove the panel 15 to expose the fan component 3 and the heat exchange component 4, which is convenient for users to clean by themselves, reduces the difficulty of subsequent cleaning and maintenance, and improves the user experience.

[0094] like Figure 17 As shown in the related art, when maintaining the heat exchange component and the fan component of the existing indoor unit, it is necessary to dismantle the panel and the internal air guide plate and other structures. Figure 17 After removing the panel of the indoor unit, the heat exchange components and fan components cannot be cleaned and maintained directly. The air guide plate and other structures still need to be disassembled to expose the heat exchange components and fan components. It is difficult for users to clean and maintain them by themselves. Generally, they can only choose professional maintenance personnel to perform disassembly and maintenance, which affects the user experience.

[0095] In the embodiment of the present application, the fan assembly 3 is arranged between the heat exchange assembly 4 and the maintenance port, the fan assembly 3 is designed horizontally, and the heat exchange assembly 4 is designed around the fan assembly 3. The panel 15 is facing the side of the fan assembly 3 to guide the gas in the shell 1. After removing the panel 15, the fan assembly 3 and the heat exchange assembly 4 can be exposed, thereby facilitating the cleaning and maintenance of the fan assembly 3 and the heat exchange assembly 4 in the shell 1.

[0096] like Figure 5 , as shown in 7-10, in some embodiments, the heat exchange component 4 includes a first heat exchanger 41 and a second heat exchanger 42, and the first heat exchanger 41 and the second heat exchanger 42 are arranged around the fan component 3.

[0097] In the present application, by configuring the heat exchange component 4 into a first heat exchanger 41 and a second heat exchanger 42, the first heat exchanger 41 and the second heat exchanger 42 are configured around the cross-flow blades 31 of the fan component 3, thereby increasing the heat exchange area with the air flow in the shell 1, facilitating sufficient heat exchange and improving heat exchange efficiency.

[0098] Optionally, the heat exchange component 4 can have more than two heat exchangers, as long as the heat exchangers are arranged around the fan component 3 and the fan component 3 is located between the heat exchanger and the maintenance port. This ensures that the heat exchange component 4 will not block the fan component 3, making it convenient to clean and maintain the fan component 3 and the heat exchange component 4.

[0099] Furthermore, an angle is formed between the first heat exchanger 41 and the second heat exchanger 42 , the fan assembly 3 is located within the angle, and the angle is set toward the maintenance port.

[0100] In the present application, one end of the first heat exchanger 41 is abutted against one end of the second heat exchanger 42, and the other end of the first heat exchanger 41 and the other end of the second heat exchanger 42 are arranged in an expanded manner, thereby forming a V-shaped angle between the first heat exchanger 41 and the second heat exchanger 42, and the fan assembly 3 is arranged within the angle, so that the first heat exchanger 41 and the second heat exchanger 42 effectively surround the fan assembly 3, and the cross-flow blades 31 of the fan assembly 3 drive the gas in the shell 1 to rotate, thereby ensuring the heat exchange area between the heat exchange assembly 4 and the gas, improving the heat exchange effect, and at the same time, the heat exchange assembly 4 will not block the fan assembly 3, making it convenient to clean and maintain the fan assembly 3.

[0101] Specifically, when the air conditioner is operating in cooling mode, the airflow enters the housing 1 from the upper first air inlet 11 under the action of the cross-flow blades 31, and is thrown out after exchanging heat with the first heat exchanger 41 located above. Part of the airflow will pass through the second heat exchanger 42 located below to exchange heat again within the housing 1, and then be sent out through the second air outlet 14 located below. Since the airflow velocity at the position of the second air outlet 14 is relatively fast, the negative pressure generated will carry out the airflow after the reheating. When the air conditioner is operating in heating mode, the airflow enters the housing 1 from the lower second air inlet 13 under the action of the cross-flow blades 31, and is thrown out after exchanging heat with the second heat exchanger 42 located below. Part of the airflow will pass through the second heat exchanger 42 located above to exchange heat again within the housing 1, and then be sent out through the first air outlet 12 located above. Since the airflow velocity at the position of the first air outlet 12 is relatively fast, the negative pressure generated will carry out the airflow after the reheating.

[0102] The first heat exchanger 41 can cover the entire first air inlet 11, so that the airflow entering through the first air inlet 11 can fully pass through the first heat exchanger 41 for heat exchange, and the gas thrown out by the cross-flow blades 31 rotates within the shell 1, and part of the airflow will pass through the second heat exchanger 42 for heat exchange again, while the other part of the airflow will be directly sent out through the second air outlet 14, and the airflow after being heated again by the second heat exchanger 42 will also be sent out through the second air outlet 14. The second heat exchanger 42 can cover the entire second air inlet 13, so that the airflow entering through the second air inlet 13 can fully pass through the second heat exchanger 42 for heat exchange, and the gas thrown out by the cross-flow blades 31 rotates within the shell 1, and part of the airflow will pass through the first heat exchanger 41 for heat exchange again, while the other part of the airflow will be directly sent out through the second air outlet 14, and the airflow after being heated again by the first heat exchanger 41 will also be sent out through the first air outlet 12.

[0103] The indoor unit controls the opening and closing states of the first air inlet 11, the first air outlet 12, the second air inlet 13 and the second air outlet 14 through the regulating mechanism 2, and can adjust the position of the air inlet and outlet of the indoor unit. In the heating mode, by opening the second air inlet 13 and the first air outlet 12 and closing the first air inlet 11 and the second air outlet 14, the fan assembly 3 allows the external air to enter the shell 1 through the second air inlet 13 at the bottom of the shell 1 and exchange heat with the heat exchange assembly 4, and then send it out through the first air outlet 12 at the top of the shell 1, which can effectively avoid the situation where the high-temperature gas is repeatedly inhaled into the shell 1, reduce energy waste, and reduce energy consumption.

[0104] An embodiment of the present application also provides an air conditioner, comprising: an outdoor unit; and the above-mentioned indoor unit.

[0105] The air conditioner provided in this application includes an indoor unit and an outdoor unit. The indoor unit is a wall-mounted indoor unit. The air supply mode of the indoor unit can be switched between upper air inlet and lower air outlet and lower air inlet and upper air outlet. When the air conditioner is in cooling mode, the upper air inlet and lower air outlet mode can be selected, ensuring that the higher temperature air in the upper area of the room is sucked into the indoor unit, and the lower temperature air is discharged from the second air outlet 14 below after heat exchange. When the air conditioner is in heating mode, the lower air inlet and upper air outlet mode can be selected, ensuring that the higher temperature air in the upper area of the room is not repeatedly sucked into the housing 1, thereby avoiding the situation where the higher temperature air is repeatedly heated. The gas sucked into the housing 1 is the lower temperature gas, thereby improving the heat exchange effect with the indoor air, avoiding energy waste, and reducing energy consumption.
