Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0094] The air conditioner 100 according to an embodiment of the present invention is described below with reference to the accompanying drawings.

[0095] like Figures 1-5 , Figures 23-27 As shown, the air conditioner 100 according to an embodiment of the present utility model includes a housing 1 and an air duct component 2.

[0096] Specifically, the housing 1 has an air inlet 121, a middle air outlet 133, a lower air outlet 134, and a top air outlet 151. The air inlet 121 is located on the rear side of the housing 1, the middle air outlet 133 and the lower air outlet 134 are located on the front side of the housing 1, the lower air outlet 134 is located below the middle air outlet 133 and adjacent to the middle air outlet 133, and the top air outlet 151 is located on the top wall of the housing 1. The air inlet 121 extends vertically and may be provided with an air inlet grille; the middle air outlet 133 extends vertically, and the width of the lower air outlet 134 in the left-right direction may be the same as the width of the middle air outlet 133 in the left-right direction; the top air outlet 151 may extend horizontally.

[0097] The air blown out from the top air outlet 151 can blow upwards and forwards, with a long air delivery distance. The air blown out from the middle air outlet 133 and the lower air outlet 134 can blow forward, achieving air delivery directly to the front. In addition, the lower air outlet 134 is positioned low, allowing air to be blown towards the user's feet or legs, thus achieving multi-dimensional air delivery from the air conditioner 100.

[0098] When the top air outlet 151 blows air, it avoids direct airflow onto the user, achieving a windless experience. Especially during cooling, it allows the cool air to descend slowly, improving the cooling effect. The lower air outlet 134 is positioned low, especially during heating, allowing the blown hot air to rise slowly, improving the heating effect. The middle air outlet 133 allows air to blow directly onto the user, meeting the user's need for direct airflow. Multiple air outlets can achieve various airflow preferences.

[0099] The air duct component 2 is disposed inside the housing 1 and includes a volute 21 and a first impeller 22 and a second impeller 23 disposed inside the volute 21. The first impeller 22 is located above the second impeller 23. The first impeller 22 is used to drive the airflow from the air inlet 121 to the top air outlet 151 and the middle air outlet 133. The second impeller 23 is used to drive the airflow from the air inlet 121 to the bottom air outlet 134.

[0100] The first impeller 22 and the second impeller 23 can be of the same or different types, and their rotational speeds can be the same or different. Different air outlet patterns can be achieved by reasonably setting the impeller type and rotational speed to meet different user needs.

[0101] In addition, such as Figures 3-7 , Figures 25-29 As shown, the air conditioner 100 also includes a heat exchange component 3, which is disposed inside the housing 1 along the airflow direction and upstream of the air duct component 2. The heat exchange component 3 is used to exchange heat with the airflow entering the housing 1 from the air inlet 121, thereby realizing the cooling and heating functions of the air conditioner 100. The heat exchange component 3 may include a heat exchanger 31, and may also include an auxiliary heater 32 for the heating mode of the air conditioner 100.

[0102] like Figure 5 , Figure 6 , Figure 27 and Figure 28As shown, the housing 1 includes a chassis 11, a rear box 12, a panel assembly 13, and a top cover 15. The lower end of the rear box 12 is connected to the chassis 11. An air inlet 121 is located on the rear box 12. An air duct component 2 is connected to the rear box 12. The lower end of the panel assembly 13 is connected to the chassis 11. The panel assembly 13 is located on the front side of the rear box 12 and is connected to the rear box 12. A middle air outlet 133 and a lower air outlet 134 are located on the panel assembly 13. The top cover 15 is connected to the upper end of the rear box 12 and the panel assembly 13. A top air outlet 151 is located on the top cover 15.

[0103] The heat exchange component 3 is fixed to the rear housing 12 with screws, and the air duct component 2 is fixed to the rear housing 12 and the heat exchange component 3. The air duct component 2 and the heat exchange component 3 are sealed around their perimeter to form a refrigeration cavity.

[0104] Optionally, the panel assembly 13 and the rear housing 12 can be snapped together. Both ends of the panel assembly 13 in the width direction are provided with multiple hooks, which are spaced apart in the vertical direction. Both ends of the rear housing 12 in the width direction are provided with multiple holes that cooperate with the hooks.

[0105] According to the embodiment of the present utility model, the air conditioner 100 has a middle air outlet 133 and a lower air outlet 134 on the front side of the housing 1, with the lower air outlet 134 located below the middle air outlet 133. A top air outlet 151 is provided on the top wall of the housing 1, and an air duct component 2 is provided inside the housing 1, including a volute 21 and a first impeller 22 and a second impeller 23 provided inside the volute 21. The first impeller 22 is located above the second impeller 23. The first impeller 22 is used to drive the airflow from the air inlet 121 to the top air outlet 151 and the middle air outlet 133, and the second impeller 23 is used to drive the airflow from the air inlet 121 to the lower air outlet 134. This allows the air conditioner 100 to achieve multi-dimensional air supply and various airflow sensations.

[0106] In some embodiments of this utility model, such as Figure 4 , Figures 11-13 , Figure 26 , Figure 33 and Figure 34As shown, the first impeller 22 is a cross-flow impeller, and the second impeller 23 is a centrifugal impeller. The cross-flow impeller delivers even and gentle airflow and has a compact structure. The central air outlet 133 extends vertically, and the length of the cross-flow impeller can match the central air outlet 133, making the internal structure of the air conditioner 100 more compact. It also makes the airflow from the central air outlet 133 and the top air outlet 151 gentler, preventing discomfort caused by direct airflow from the central air outlet 133 to the user. The centrifugal impeller has the advantages of high air volume and high air pressure. Specifically, compared to other types of impellers, under the same power input, the centrifugal impeller can deliver more gas and overcome greater system resistance, delivering gas to a greater distance or higher position. The second impeller 23 being a centrifugal impeller enables long-distance air delivery and high-volume air delivery from the lower air outlet 134.

[0107] In some embodiments of this utility model, such as Figure 9 , Figures 11-13 , Figures 32-34 As shown, the air duct component 2 also includes a first motor 24 and a second motor 25. The first motor 24 is located above and connected to the volute 21, and is used to drive the first impeller 22 to rotate. The second motor 25 is located below and connected to the volute 21, and is used to drive the second impeller 23 to rotate. The first impeller 22 and the second impeller 23 are driven to rotate by the first motor 24 and the second motor 25, respectively. The rotational speeds of the first impeller 22 and the second impeller 23 can be adjusted separately, thereby adjusting the air volume and air speed of multiple air outlets. The multiple air outlets can achieve different air delivery modes.

[0108] The first motor 24 and the second motor 25 independently control the rotation of the first impeller 22 and the second impeller 23, respectively, thereby enabling simultaneous airflow from multiple air outlets as well as airflow from a single air outlet. For example, when the first motor 24 is working and the second motor 25 is not working, only the first motor 24 drives the first impeller 22 to rotate, and only the top air outlet 151 and the middle air outlet 133 can emit air. When the second motor 25 is working and the first motor 24 is not working, only the second motor 25 drives the second impeller 23 to rotate, and only the bottom air outlet 134 emits air. When both the first motor 24 and the second motor 25 are working, the first motor 24 can drive the first impeller 22 to rotate, and the second motor 25 can drive the second impeller 23 to rotate, allowing airflow from the top air outlet 151, the middle air outlet 133, and the bottom air outlet 134.

[0109] Furthermore, the rotation of the first fan wheel 22 and the second fan wheel 23 is independent of each other, allowing for free adjustment of the air conditioner 100's cooling and heating modes according to user needs, thereby improving comfort. For example, in cooling mode, cold air sinks, so only the first fan wheel 22 can be controlled to rotate, causing some cold air to slowly sink from the top air outlet 151, improving the cooling effect. In heating mode, hot air rises, so only the second fan wheel 23 can be controlled to rotate, causing hot air to slowly rise from the bottom air outlet 134, improving the heating effect and simultaneously providing a foot-warming effect.

[0110] In some embodiments of this utility model, such as Figures 1-4 As shown, a switch door 152 is provided at the top air outlet 151, which is used to open or close the top air outlet 151. Thus, the top air outlet 151 can be opened when the air conditioner 100 is in use and closed when the air conditioner 100 is turned off, which serves to prevent dust and insects.

[0111] Furthermore, such as Figures 1-4 As shown, the rear end of the switch door 152 is rotatably connected to the rear end of the top air outlet 151. When the switch door 152 opens the top air outlet 151, the switch door 152 tilts upward in the direction from back to front. The switch door 152 can act as an air guide plate to guide the air blown out of the top air outlet 151, directing the air blown out of the top air outlet 151 forward and upward, thereby increasing the air delivery distance.

[0112] In some embodiments of this utility model, when the top air outlet 151 is closed by the switch door 152, the upper surface of the switch door 152 is flush with the outer top wall of the housing 1, thereby making the outer top wall of the air conditioner 100 flatter, which is convenient for protecting the top of the housing 1 or placing items on the top of the air conditioner 100.

[0113] Furthermore, a sealing ring is provided on the outer peripheral wall of the switch door 152 or at the top air outlet 151. When the switch door 152 closes the top air outlet 151, the sealing ring is located between the switch door 152 and the top air outlet 151, which can seal the gap between the switch door 152 and the top air outlet 151, and can better prevent dust and water, and ensure the reliability of the air conditioner 100.

[0114] In some embodiments of this utility model, such as Figures 4-6As shown, the volute 21 has a first air duct 2111, and a first impeller 22 is disposed within the first air duct 2111. One end of the first air duct 2111 is connected to the air inlet 121. The air conditioner 100 also includes an air duct component 153, which is located on the upper and front sides of the volute 21, with its upper end connected to the top air outlet 151. The middle air outlet 133 and the lower end of the air duct component 153 are connected to the other end of the first air duct 2111. This facilitates the guidance of the air blown out of the first air duct 2111 to the top air outlet 151 and out of the top air outlet 151.

[0115] Specifically, the cross-sectional shape of the air duct component 153 is the same as that of the top air outlet 151, the width of the air duct component 153 is the same as that of the top air outlet 151, and the length of the air duct component 153 is the same as that of the top air outlet 151. This facilitates the connection between the air duct component 153 and the top wall of the housing 1, and at the same time facilitates the airflow in the first air duct 2111 to flow through the air duct component 153 to the top air outlet 151, thereby reducing airflow resistance and noise.

[0116] In some embodiments of this utility model, such as Figures 17-20 As shown, for reference Figure 4 The air conditioner 100 also includes a top air guide plate 154, which is rotatably disposed at the lower end of the air duct 153. The top air guide plate 154 has a first position and a second position. In the first position, the top air guide plate 154 is located in front of the first air duct 2111 and is at least partially disposed opposite to the outlet of the first air duct 2111 in the front-back direction. In the back-to-front direction, the top air guide plate 154 is tilted upward to guide the airflow of the air inlet 121 into the air duct 153. In the second position, the top air guide plate 154 is located inside the air duct 153 and blocks the air duct 153.

[0117] When the top air outlet 151 is opened, the top air guide plate 154 can be rotated to the first position. The upper end of the top air guide plate 154 can be close to or attached to the front side wall of the air duct component 153. For example, the upper end of the top air guide plate 154 extends into the air duct component 153 and is close to or attached to the front side wall of the air duct component 153, or the upper end of the top air guide plate 154 is located on the lower side of the air duct component 153 and is close to or attached to the front side wall of the air duct component 153. The lower end of the top air guide plate 154 is located close to the air duct component 2, and at least a portion of the top air guide plate 154 is opposite to the outlet of the first air duct 2111. The top air guide plate 154 can block the air from the outlet of the first air duct 2111, and can guide the air blown out from the portion opposite to the top air guide plate 154 into the air duct component 153 and blow it out from the top air outlet 151. In the absence of a power device, it is convenient to guide the air in the first air duct 2111 to the top air outlet 151.

[0118] When the top air outlet 151 is closed, the top air guide plate 154 can be rotated to the second position, which allows the top air guide plate 154 to rotate into the air duct component 153 to block the air duct component 153. On the one hand, this prevents the air in the first air duct 2111 from leaking through the air duct component 153 and the top air outlet 151, reducing the air volume of the middle air outlet 133. On the other hand, it can reduce the obstruction of the top air guide plate 154 to the air in the first air duct 2111, allowing the air in the first air duct 2111 to flow forward better, reducing airflow resistance and noise.

[0119] It is understood that the top air guide plate 154 and the opening and closing door 152 can open or close synchronously. For example, when the opening and closing door 152 opens the top air outlet 151, the top air guide plate 154 rotates to the first position to open the air duct component 153. When the opening and closing door 152 closes the top air outlet 151, the top air guide plate 154 rotates to the second position to block the air duct component 153.

[0120] In some embodiments of this utility model, such as Figure 18 As shown, the top air guide plate 154 is an arc-shaped plate. The arc shape facilitates airflow, improves airflow guidance, and reduces airflow resistance and noise. Specifically, in the first position, the top air guide plate 154 protrudes downwards and forwards. This allows the airflow from the first air duct 2111 to flow forward and encounter the top air guide plate 154, enabling it to flow upwards into the air duct 153 under the action of the top air guide plate 154, and then to the top air outlet 151.

[0121] In some embodiments of this utility model, such as Figure 22 As shown, the duct component 153 is equipped with a door motor 155, which is connected to the door 152 and drives the door 152 to rotate. The duct component 153 also has a plate motor 156, which is connected to the top air guide plate 154 and drives the top air guide plate 154 to rotate. The door motor 155 and plate motor 156 can communicate with the control module of the air conditioner 100, enabling automated control of the opening and closing of the door 152 and the top air guide plate 154, facilitating user operation.

[0122] In some embodiments of this utility model, such as Figure 26 , Figure 28 , Figures 30-34As shown, the housing 1 is provided with a fresh air inlet 122. Outdoor fresh air flows from the fresh air inlet 122 to the air outlet 134 under the action of the second impeller 23. This allows the introduction of fresh air and the blowing of air into the room to share a single second impeller 23, which can reduce the number of parts such as motors and impellers, thereby reducing costs. At the same time, it can reduce the space occupied inside the air conditioner 100, which is conducive to the compact layout of the air conditioner 100 and facilitates the miniaturization of the air conditioner 100.

[0123] In addition, when the second impeller 23 rotates and the heat exchange component 3 is working, the second impeller 23 can both introduce indoor air from the air inlet 121 into the air conditioner 100 to exchange heat with the heat exchange component 3 and then discharge it into the room, and allow outdoor fresh air to enter the air conditioner 100 through the fresh air inlet 122 and be discharged into the room. The introduced fresh air and the air after heat exchange are mixed at the volute 21 and the lower air outlet 134, so that the temperature of the blown fresh air is more suitable and the user's comfort is improved.

[0124] In some embodiments of this utility model, such as Figures 33-37 As shown, the volute 21 has a second air duct 2123, and a second impeller 23 is disposed within the second air duct 2123. The second air duct 2123 has a first inlet 2124 communicating with the air inlet 121 and a second inlet 2125 communicating with the fresh air inlet 122. The second impeller 23 can drive airflow from the first inlet 2124 and the second inlet 2125 into the second air duct 2123, and then flow down to the air outlet 134 through the outlet of the second air duct 2123.

[0125] In some embodiments of this utility model, such as Figure 26 , Figures 32-34 As shown, the first inlet 2124 is located on the upper wall of the second air duct 2123, and the second inlet 2125 is located on the lower wall of the second air duct 2123. The first inlet 2124 is positioned upwards to facilitate the entry of air from the air inlet 121 into the second air duct 2123, reducing airflow resistance and noise. Figure 28 In the example shown, the fresh air inlet 122 is located below the air inlet 121, and the second inlet 2125 is set downwards to facilitate connection with the fresh air inlet 122.

[0126] In some embodiments of this utility model, such as Figures 8-13 , Figures 30-34As shown, the volute 21 includes a middle volute 211 and a lower volute 212. The first impeller 22 is disposed in the middle volute 211. Specifically, the middle volute 211 is provided with a first air duct 2111. The front and rear sides of the first air duct 2111 are open. The first air duct 2111 connects the air inlet 121 and the middle air outlet 133, and also connects the air inlet 121 and the top air outlet 151. The first impeller 22 is disposed in the first air duct 2111 and is used to drive the airflow from the air inlet 121 through the first air duct 2111 to the middle air outlet 133 and the top air outlet 151. The lower volute 212 is located below the middle volute 211. The lower volute 212 defines the second air duct 2123, which connects the air inlet 121 and the lower air outlet 134. The second impeller 23 is located in the second air duct 2123 of the lower volute 212 and is used to drive the airflow from the air inlet 121 to the lower air outlet 134.

[0127] When the air conditioner 100 is provided with a fresh air inlet 122 on the housing 1, the second air duct 2123 is also connected to the fresh air inlet 122, and the second impeller 23 is also used to drive the outdoor fresh air to flow from the fresh air inlet 122 to the lower air outlet 134.

[0128] exist Figure 4 and Figure 26 In the example shown, the first impeller 22 is a cross-flow impeller, and the second impeller 23 is a centrifugal impeller. At least a portion of the second impeller 23 is located below the air inlet 121, and its axis extends vertically. The first inlet 2124 of the second air duct 2123 is positioned towards the first impeller 22 and spaced apart from the intermediate volute 211, facilitating air intake into the second air duct 2123. The outlet of the second air duct 2123 faces forward. Part of the airflow entering from the air inlet 121 flows directly into the first air duct 2111, is driven by the first impeller 22 to the intermediate air outlet 133 and the top air outlet 151, and part flows downward into the second air duct 2123, is driven by the second impeller 23 to the lower air outlet 134.

[0129] When the second air duct 2123 includes the second inlet 2125 and the fresh air inlet 122 is provided on the housing 1, the second inlet 2125 of the second air duct 2123 faces downward. The outdoor fresh air entering from the fresh air inlet 122 flows into the second air duct 2123 through the second inlet 2125 and is driven to the lower air outlet 134 by the second impeller 23.

[0130] In some embodiments of this utility model, such as Figures 8-13 , Figures 30-34As shown, the lower volute 212 includes a volute housing 2121 and a volute cover 2122. The volute cover 2122 and the volute housing 2121 are arranged vertically, with the volute housing 2121 located above the volute cover 2122. The volute housing 2121 is connected to the volute cover 2122 and defines a second air duct 2123 for accommodating the second impeller 23. The volute cover 2122 and the volute housing 2121 together define the inlet and outlet of the second air duct 2123, thereby facilitating the assembly of the second impeller 23 into the second air duct 2123. The volute cover 2122 and the volute housing 2121 can be connected by fasteners or snap-fit ​​connections, such as... Figures 42-44 As shown, the first inlet 2124 is located on the volute housing 2121, and the second inlet 2125 is located on the volute cover 2122.

[0131] Optionally, such as Figure 42 The first inlet 2124 is a large circular opening.

[0132] Optionally, such as Figure 43 and Figure 44 As shown, for reference Figure 33 and Figure 34 The second motor 25 is located below the volute cover 2122. When the air conditioner 100 has a fresh air function, a second inlet 2125 is provided on the volute cover 2122. The second inlet 2125 of the volute cover 2122 is a circular opening. A support frame 2127 is provided at the second inlet 2125 to support and limit the second motor 25. The support frame 2127 includes a fixing part and multiple connecting arms. The fixing part is located inside the second inlet 2125. The fixing part has a tube hole for the output shaft of the second motor 25 to pass through. One end of the connecting arm is connected to the fixing part, and the other end of the connecting arm is connected to the volute cover 2122. Multiple connecting arms are spaced apart along the circumferential direction of the fixing part. The side end face of the motor facing the volute cover 2122 abuts against the support frame 2127.

[0133] In addition, such as Figure 33 and Figure 34 As shown, the air duct component 2 also includes a motor cover 2126, which is located on the side of the second motor 25 opposite to the volute cover 2122. The motor cover 2126 is connected to the volute cover 2122 to confine the second motor 25 between the support frame 2127 and the motor cover 2126. When the air conditioner 100 has a fresh air function, the motor cover 2126 includes a central portion and multiple connecting ribs. The multiple connecting ribs are spaced apart along the circumferential direction of the central portion. One end of each connecting rib is connected to the central portion, and the other end extends radially along the central portion and is connected to the volute cover 2122.

[0134] The space between two adjacent connecting ribs and the space between two adjacent connecting arms can be used for fresh air flow.

[0135] Furthermore, the volute housing 2121 is located above the volute cover 2122 and is integral with the intermediate volute housing 211. This allows the lower volute housing 212 to be connected to the intermediate volute housing 211, thereby fixing the second impeller 23 and the first impeller 22 together through the volute housing 21, ensuring the coaxiality of the second impeller 23 and the first impeller 22.

[0136] Of course, this utility model is not limited to this; the volute housing 2121 and the intermediate volute housing 211 can be separate parts.

[0137] In some embodiments of this utility model, such as Figures 11-13 As shown, the first impeller 22 is mounted on a bearing housing 214 on the rotating shaft at the end opposite to the first motor 24. The bearing housing 214 is fixed on the intermediate volute 211, thereby facilitating the rotation of the first impeller 22.

[0138] In some embodiments of this utility model, such as Figure 32 , Figure 37 , Figure 40 and Figure 41 As shown, the second impeller 23 includes an end cap 231, a first blade 232, and a second blade 233. Multiple first blades 232 are located above the end cap 231 and are spaced apart along the circumferential direction of the end cap 231. Multiple second blades 233 are located below the end cap 231 and are also spaced apart along the circumferential direction of the end cap 231. The first blades 232 can drive airflow from the air inlet 121 to the air outlet 134, and the second blades 233 can drive fresh air from the fresh air inlet 122 to the air outlet 134, facilitating the introduction of indoor air and fresh air through a single impeller.

[0139] Furthermore, such as Figure 40 and Figure 41 As shown, the end cover 231 has multiple spaced through holes 2311 for airflow. When the air conditioner 100 operates only for cooling or heating without opening the fresh air supply, the airflow enters through the first inlet 2124 near the heat exchange component 3 of the centrifugal impeller. At the same time, some of the airflow flows downward through the through holes 2311 on the centrifugal impeller end cover 231. The first blade 232 and the second blade 233 work simultaneously to drive the airflow to the lower air outlet 134. In this way, all the blades of the centrifugal impeller can play a role, which increases the driving force of the centrifugal impeller and helps to increase the air volume and air delivery distance. When the air conditioner 100 turns on the fresh air function but not the cooling or heating function, the airflow enters through the second inlet 2125 of the centrifugal impeller away from the heat exchange component 3. At the same time, part of the airflow flows upward through the through hole 2311 on the centrifugal impeller end cover 231. The first blade 232 and the second blade 233 work simultaneously to drive the airflow to the lower air outlet 134. In this way, all the blades of the centrifugal impeller can play a role, which increases the driving force of the centrifugal impeller and helps to increase the air volume and air delivery distance.

[0140] In some embodiments of this utility model, such as Figures 33-37 As shown, the air conditioner 100 also includes a fresh air duct component 9. One end of the fresh air duct component 9 is connected to the fresh air inlet 122, and the other end is connected to the second inlet 2125 and the volute 21. The fresh air duct component 9 can introduce fresh air from the fresh air inlet 122 to the first inlet 2124, so that the second impeller 23 can drive the fresh air to the lower air outlet 134.

[0141] Furthermore, such as Figures 33-37 As shown, the air conditioner 100 also includes a fresh air valve 91, which is rotatably disposed within the fresh air duct component 9 for opening or closing the fresh air duct component 9. When the fresh air function is activated, the fresh air valve 91 can be opened. Under the action of the second impeller 23, outdoor fresh air flows through the fresh air inlet 122, the fresh air duct component 9, the first inlet 2124, and the second air duct 2123 to the lower air outlet 134, thereby achieving the function of drawing fresh air into the room. In addition, since the air inlet 121 is in a normally open state, when the fresh air function is activated, regardless of whether the heat exchange component 3 is operating, the first inlet 2124 will simultaneously draw in air, which will mix with the fresh air and blow it out, avoiding the discomfort of the fresh air blowing directly into people. When the air conditioner 100 is operating only for cooling or heating, the fresh air duct component 9 can be closed through the fresh air valve 91, allowing only the first inlet 2124 to draw in air.

[0142] In some embodiments of this utility model, such as Figures 33-35 As shown, the air conditioner 100 also includes a third motor 92, which is located outside the fresh air duct component 9 and is used to drive the fresh air valve 91 to rotate. The third motor 92 can communicate with the control module of the air conditioner 100, enabling automated control of the opening and closing of the fresh air valve 91, which is convenient for users.

[0143] In some embodiments of this utility model, such as Figure 35 and Figure 37 As shown, the fresh air duct component 9 includes a fresh air chamber 93 and a duct 94. One end of the fresh air chamber 93 is connected to the volute 21 and communicates with the second inlet 2125. A fresh air valve 91 is rotatably disposed within the fresh air chamber 93. One end of the duct 94 is connected to the end of the fresh air chamber 93 opposite to the first inlet 2124, and the other end is connected to the fresh air inlet 122. The inner diameter of at least one end of the fresh air chamber 93 near the second inlet 2125 is larger than the inner diameter of the duct 94. This facilitates the connection between the fresh air duct component 9 and the volute 21.

[0144] Among them, the fresh air cavity component 93 and the duct 94 are separate components, which facilitates the installation of the fresh air valve 91.

[0145] Optionally, the fresh air cavity component 93 is a rigid structural component, which facilitates the connection between the fresh air duct component 9 and the volute 21 and improves the reliability of the connection between the fresh air duct component 9 and the volute 21.

[0146] Optionally, the duct 94 is a flexible hose, which facilitates the connection between the fresh air chamber component 93 and the fresh air inlet 122.

[0147] In some embodiments of this utility model, such as Figure 35 and Figures 37-39 As shown, the fresh air chamber component 93 includes a first section 931 and a second section 932. One end of the first section 931 is connected to the volute 21, and one end of the second section 932 is connected to the other end of the first section 931. The end of the second section 932 facing away from the first section 931 is connected to the duct 94. The inner diameter of the first section 931 is larger than the inner diameter of the second section 932, and the fresh air valve 91 is rotatably disposed within the second section 932.

[0148] Furthermore, such as Figure 35 and Figures 37-39 As shown, the duct 94 includes a main body section 941 and a horn section 942. One end of the main body section 941 is connected to the fresh air inlet 122. One end of the horn section 942 is connected to one end of the main body section 941, and the other end is connected to the second section 932 of the fresh air cavity component 93. In the direction from the main body section 941 to the horn section 942, the inner diameter of the horn section 942 gradually increases, while the inner diameter of the main body section 941 remains unchanged.

[0149] In some embodiments of this utility model, such as Figures 14-16 , Figure 21 and Figure 22 As shown, for reference Figure 1 A first air guide plate assembly 4 is provided at the middle air outlet 133 and the lower air outlet 134. The first air guide plate assembly 4 includes a plurality of first air guide plates 41. The plurality of first air guide plates 41 are spaced apart in the left and right direction. The first air guide plates 41 are rotatable in the left and right direction. The upper end of the first air guide plate 41 extends to the upper end of the middle air outlet 133 and the lower end extends to the lower end of the lower air outlet 134.

[0150] It is understood that the rotation axis of the first air guide plate 41 extends in the vertical direction. By adjusting the rotation angle of multiple first air guide plates 41, the air delivery angle of the middle air outlet 133 and the lower air outlet 134 in the left and right directions can be adjusted. In addition, the middle air outlet 133 and the lower air outlet 134 can be adjusted synchronously, which simplifies the adjustment process.

[0151] In some embodiments of this utility model, such as Figures 14-16 , Figure 21 and Figure 22As shown, the first air guide plate assembly 4 also includes a plurality of first air guide motors 43, which are connected to a plurality of first air guide plates 41 and are used to drive the plurality of first air guide plates 41 to rotate respectively. For example, in Figure 21 and Figure 22 In the example shown, there are four first air guide plates 41 and four first air guide motors 43. The four first air guide motors 43 correspond one-to-one with the four first air guide plates 41. The first air guide motor is located at the upper end of the first air guide plate 41.

[0152] In some embodiments of this utility model, such as Figure 21 and Figure 22 As shown, a second air outlet grille 8 is provided at the lower air outlet 134, located upstream of the first air guide plate assembly 4 along the airflow direction. The second air outlet grille 8 serves a protective function, preventing external insects and rodents from entering the air conditioner 100 through the lower air outlet 134 and preventing users' hands from accidentally being damaged by the fan wheel when they put their hands inside the air conditioner 100, thus protecting both the air conditioner 100 and the user.

[0153] Furthermore, such as Figure 21 and Figure 22 As shown, for reference Figure 4 The second air outlet grille 8 includes multiple grille strips 81 spaced apart in the vertical direction, and the grille strips 81 are inclined downward in the rear-to-front direction. This allows the air from the lower air outlet 134 to blow downward, avoiding direct airflow to the user. Especially when heating, it can realize the downward blowing of hot air to achieve the foot warming mode, and can also make the hot air rise slowly to improve the heating effect.

[0154] In some embodiments of this utility model, such as Figure 47 and Figure 48 As shown, a first air guide plate assembly 4 is provided at the central air outlet 133. The first air guide plate assembly 4 includes multiple first air guide plates 41, which are spaced apart in the left-right direction and are rotatable in the left-right direction. It can be understood that the rotation axis of the first air guide plate 41 extends in the up-down direction. By adjusting the rotation angle of the multiple first air guide plates 41, the air delivery angle of the central air outlet 133 in the left-right direction can be adjusted.

[0155] Furthermore, the first air guide plate assembly 4 also includes a first connecting rod 42, which extends in the left-right direction and is rotatably connected to multiple first air guide plates 41. This first connecting rod is used to drive the multiple first air guide plates 41 to rotate synchronously, facilitating adjustment of the air delivery angle of the central air outlet 133. Multiple connecting rods can be used, and these connecting rods are spaced apart in the up-down direction.

[0156] exist Figure 46 and Figure 47In the example shown, multiple first air guide plates 41 are divided into two groups along the left and right directions, and each group of first air guide plates 41 rotates synchronously through multiple first connecting rods 42 spaced apart along the up and down directions.

[0157] Furthermore, the first air guide plate assembly 4 also includes a first air guide motor 43, which is connected to the first connecting rod 42 or the first air guide plate 41 to drive the first air guide plate 41 to rotate. The first air guide motor 43 can be one or more. Figure 46 and Figure 47 In the example shown, each group of first air guide plates 41 is driven by a first air guide motor 43, which is connected to one of the first air guide plates 41.

[0158] In some embodiments of this utility model, such as Figures 14-16 , Figure 21 and Figure 22 As shown, a second air guide plate assembly 5 is provided at the central air outlet 133. The second air guide plate assembly 5 includes multiple second air guide plates 51, which are spaced apart in the vertical direction. The second air guide plates 51 are rotatable in the vertical direction, and their rotation axes can extend in the horizontal direction. By adjusting the rotation angle of the multiple second air guide plates 51, the air delivery angle of the central air outlet 133 in the vertical direction can be adjusted. The combination of multiple first air guide plates 41 and multiple second air guide plates 51 can achieve three-dimensional air delivery at the central air outlet 133, improving the air delivery angle and air delivery range of the central air outlet 133.

[0159] like Figure 3 As shown, the second air guide plate assembly 5 is located upstream of the first air guide plate assembly 4 along the airflow direction. This facilitates the arrangement of the first air guide plate 41 and the second air guide plate 51, making the structure of the air conditioner 100 more compact.

[0160] Furthermore, such as Figures 14-16 , Figure 21 and Figure 22 As shown, the second air guide plate assembly 5 also includes a second connecting rod 52, which extends in the vertical direction and is rotatably connected to multiple second air guide plates 51. This is used to drive the multiple second air guide plates 51 to rotate synchronously, so as to facilitate the adjustment of the air delivery angle of the middle air outlet 133.

[0161] Furthermore, such as Figures 14-16 , Figure 21 and Figure 22 As shown, the second air guide plate assembly 5 also includes a second air guide motor 53, which is connected to the second connecting rod 52 or the second air guide plate 51 to drive the second air guide plate 51 to rotate. The second air guide motor 53 can be one or more. Figure 22In the example shown, the second air guide motor 53 is connected to the second link 52 and is used to drive the second link 52 to move in the up and down direction, thereby driving the multiple second air guide plates 51 to rotate.

[0162] In some embodiments of this utility model, such as Figure 21 and Figure 22 As shown, for reference Figure 3 A first air outlet grille 7 is provided at the central air outlet 133, located between the first air guide plate assembly 4 and the second air guide plate assembly 5 along the airflow direction. The first air outlet grille 7 serves a protective function, preventing external insects and rodents from entering the air conditioner 100 through the central air outlet 133 and preventing users' hands from accidentally being damaged by the fan wheel when they put their hands inside the air conditioner 100, thus protecting the air conditioner 100 and the user.

[0163] The first air outlet grille 7 may include a plurality of first ribs and a plurality of second ribs.
