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

[0057] Traditional air conditioner indoor units typically have only one air outlet, which changes the airflow direction by swinging blades. This single air outlet pattern results in a poor user experience.

[0058] Therefore, this invention provides an indoor air conditioning unit 100 having at least an upper air outlet 151 and a lower air outlet 152 located on the front side, and side air outlets 16 located on both sides, and is equipped with a switching element 2 to allow the air outlets used for air distribution to be switchable.

[0059] This is more conducive to improving the downward airflow effect in the air conditioner's heating mode and the upward airflow effect in the air conditioner's cooling mode, enriching the air outlet mode of the indoor unit 100 and improving the user experience.

[0060] The following is combined with Figures 1 to 12 This describes an embodiment of the air conditioner indoor unit 100.

[0061] like Figures 1-12 As shown, the indoor unit 100 of the air conditioner according to an embodiment of the present invention includes: a housing 1, a fan assembly 3, and a switching component 2.

[0062] The housing 1 defines a space for accommodating the internal structure of the indoor air conditioning unit 100. The housing 1 is provided with an air inlet 111 and an air outlet. The fan assembly 3 is located inside the housing 1 and is used to drive the airflow from the air inlet 111 on the housing 1 to the air outlet on the housing 1. In other words, the fan assembly 3 is used to drive the airflow to the air outlet.

[0063] The air outlets on the housing 1 include: a front air outlet 15 and a side air outlet 16, wherein the front air outlet 15 includes an upper air outlet 151 and a lower air outlet 152.

[0064] In the left-right direction, the side air outlet 16 is located to the left and / or right of the front air outlet 15. In the up-down direction, the upper air outlet 151 is located above the side air outlet 16, and the lower air outlet 152 is located below the side air outlet 16. The multiple air outlets together construct a multi-directional three-dimensional air outlet mode for the indoor air conditioner, giving the air conditioner a variety of air outlet modes, improving the user experience, and providing a structural basis for the indoor unit 100 to adopt different air supply modes in different modes. For example, in cooling mode, the indoor air conditioner can prioritize the upper air outlet 151 as the air outlet for outward air supply. Under this air supply mode, the air conditioner has a better cooling effect. In heating mode, the indoor air conditioner can prioritize the lower air outlet 152 as the air outlet for outward air supply. Under this air supply mode, the air conditioner has a better heating effect.

[0065] The impeller assembly 3 drives the airflow from the air inlet 111 to the air outlet 32 ​​of the impeller assembly 3, that is, the impeller assembly 3 delivers air to the air outlet through the air outlet 32. The housing 1 has multiple first air duct spaces 101 connected to the air outlet 32 ​​of the impeller assembly 3. The impeller assembly 3 drives the airflow from the air outlet 32 ​​to the first air duct spaces 101, and after being guided by the first air duct spaces 101, it flows to the air outlet on the housing 1. The impeller assembly 3 is used to deliver air to the front air outlet 15 and the side air outlet 16.

[0066] Each first air duct space 101 is provided with a switching element 2 so that the upper air outlet 151 and the side air outlet 16 are switched to be connected with the air outlet 32 ​​through the first air duct space 101, and the lower air outlet 152 and the side air outlet 16 are switched to be connected with the air outlet 32 ​​through the first air duct space 101.

[0067] By controlling the switching element 2, the indoor unit 100 of the air conditioner can be switched to different air outlet modes.

[0068] Specifically, when the upper air outlet 151 is connected to the corresponding air outlet 32 ​​through the first air duct space 101, and the lower air outlet 152 is connected to the side air outlet 16 through the first air duct space 101, the air conditioner indoor unit 100 supplies air outward by being driven by the impeller assembly 3. The airflow flows from the air inlet 111 to the air outlet 32 ​​of the impeller assembly 3. The airflow at the air outlet 32 ​​corresponding to the upper air outlet 151 passes through the first air duct space 101, is guided by the switching element 2 within the first air duct space 101, and flows to the upper air outlet 151. The airflow at the air outlet 32 ​​corresponding to the lower air outlet 152 passes through the first air duct space 101, is guided by the switching element 2 within the first air duct space 101, and flows to the side air outlet 16. The air conditioner indoor unit 100 mainly supplies air outward by the upper air outlet 151 and the side air outlet 16.

[0069] This air delivery method is more suitable for the cooling mode of air conditioners. When the air conditioner sends out cold air, since cold air tends to flow downwards in the room, the air conditioner sends air to the upper part of the room, which helps to ensure a uniform indoor temperature and promotes even cooling, resulting in better cooling performance.

[0070] Specifically, when the lower air outlet 152 is connected to the corresponding air outlet 32 ​​through the first air duct space 101, and the air outlet 32 ​​corresponding to the upper air outlet 151 is connected to the side air outlet 16 through the first air duct space 101, the way the air conditioner indoor unit 100 sends air out is that it is driven by the impeller assembly 3, and the airflow flows from the air inlet 111 to the air outlet 32 ​​of the impeller assembly 3. The airflow at the air outlet 32 ​​corresponding to the lower air outlet 152 passes through the first air duct space 101, is guided by the switching element 2 in the first air duct space 101, and flows to the lower air outlet 152. The airflow at the air outlet 32 ​​corresponding to the upper air outlet 151 passes through the first air duct space 101, is guided by the switching element 2 in the first air duct space 101, and flows to the side air outlet 16. The air conditioner indoor unit 100 mainly sends air out through the lower air outlet 152 and the side air outlet 16.

[0071] This air supply method is suitable for the heating mode of air conditioners. When the air conditioner sends hot air outward, since hot air tends to flow upward in the room, the air conditioner sends air to the lower part of the room, which helps to ensure a uniform indoor temperature and promotes even heating, resulting in better heating performance of the air conditioner.

[0072] The upper air outlet 151 is connected to the corresponding air outlet 32 ​​through the first air duct space 101, and the lower air outlet 152 is connected to the corresponding air outlet 32 ​​through the first air duct space 101. At this time, the way the air conditioner indoor unit 100 sends air out is that it is driven by the impeller assembly 3. The airflow flows from the air inlet 111 to the air outlet 32 ​​of the impeller assembly 3. The airflow at the air outlet 32 ​​corresponding to the upper air outlet 151 passes through the first air duct space 101. Within the first air duct space 101, it is guided by the switching element 2 and flows to the upper air outlet 151. The airflow at the air outlet 32 ​​corresponding to the lower air outlet 152 passes through the first air duct space 101. Within the first air duct space 101, it is guided by the switching element 2 and flows to the lower air outlet 152. The air conditioner indoor unit 100 sends air out together from the upper air outlet 151 and the lower air outlet 152.

[0073] This air delivery method is suitable for the rapid cooling or rapid heating mode of air conditioners. In this mode, the air conditioner can deliver air outward in multiple directions and three dimensions, providing a more powerful and rapid cooling or heating effect and improving the user experience.

[0074] When the air outlet 32 ​​corresponding to the lower air outlet 152 is connected to the side air outlet 16 through the first air duct space 101, and the air outlet 32 ​​corresponding to the upper air outlet 151 is connected to the side air outlet 16 through the first air duct space 101, the way the air conditioner indoor unit 100 sends air out is that it is driven by the impeller assembly 3, and the airflow flows from the air inlet 111 to the air outlet 32 ​​of the impeller assembly 3. The airflow at the air outlet 32 ​​corresponding to the lower air outlet 152 passes through the first air duct space 101, and is guided by the switching element 2 in the first air duct space 101, and flows to the side air outlet 16. The airflow at the air outlet 32 ​​corresponding to the upper air outlet 151 passes through the first air duct space 101, and is guided by the switching element 2 in the first air duct space 101, and flows to the side air outlet 16. The air conditioner indoor unit 100 mainly sends air out through the side air outlet 16.

[0075] This air supply method is suitable for the side air outlet mode of the air conditioner. In this mode, the air conditioner mainly supplies air outward from the side air outlet 16, avoiding direct airflow to the user and improving the user experience.

[0076] In summary, by switching the air conditioner indoor unit 100 to deliver air from different air outlets via the switching component 2, the air delivery mode of the air conditioner indoor unit 100 is diversified, thereby improving the user experience.

[0077] According to an embodiment of the present invention, the air conditioner indoor unit 100 has more diverse air outlet modes, better cooling and heating effects, and improves the user experience.

[0078] Reference Figures 2-8 The housing 1 also includes a second air duct space 102, spaced apart from the first air duct space 101. The second air duct space 102 connects the air outlet 32 ​​and the side air outlet 16. In other words, besides the air outlet 32 ​​corresponding to the upper air outlet 151 and the lower air outlet 152 (i.e., the air outlet 32 ​​corresponding to the first air duct space 101), there are additional openings corresponding to the second air duct space 102. The airflow at these partial air outlets 32 flows through the second air duct space 102 to the side air outlet 16, and is then delivered to the outside through the side air outlet 16. The second air duct space 102 is spaced apart from the first air duct space 101, meaning the first air duct space 101 and the second air duct space 102 are independent of each other, and the airflow does not flow between them.

[0079] like Figure 3 , Figure 7 and Figure 10 As shown, the wind turbine assembly 3 includes multiple wind turbines 31 arranged in sequence. Each wind turbine 31 is provided with an air outlet 32. Each first air duct space 101 and second air duct space 102 is connected to the corresponding air outlet 32.

[0080] In other words, the impeller assembly 3 is composed of multiple impellers 31 arranged in sequence. Compared with the single impeller 31 in the prior art, the air conditioner indoor unit 100 is supplied with air by the impeller assembly 3 composed of multiple impellers 31, which can increase the air volume and increase the distribution distance of the air volume in the axial direction of the impeller 31, so as to achieve long-distance air delivery.

[0081] In some embodiments of the present invention, each impeller 31 is a centrifugal impeller. Due to its high efficiency and strong gas pressure boosting capability, the centrifugal impeller can provide a larger air volume to the air conditioner, increasing the air delivery distance of the indoor unit 100.

[0082] In other embodiments, some of the multiple impellers 31 can be centrifugal impellers, and the other part can be cross-flow impellers. For example, the multiple impellers 31 include three impellers 31, wherein the uppermost impeller 31 and the lowermost impeller 31 are centrifugal impellers, and the middle impeller 31 is a cross-flow impeller, so as to combine the advantages of centrifugal impellers and cross-flow impellers and improve the air supply effect of the air conditioning indoor unit 100.

[0083] In some embodiments of the present invention, such as Figure 3 , Figure 7 and Figure 10 As shown, multiple centrifugal impellers are coaxially arranged and fixedly connected, and the multiple centrifugal impellers are driven to rotate by the same motor. This simplifies the structure of the air conditioner indoor unit 100, reduces the control difficulty of the air conditioner indoor unit 100, and reduces the production cost of the air conditioner indoor unit 100.

[0084] The coaxial arrangement of multiple centrifugal impellers can also prevent the impeller assembly 3 from occupying too much space inside the casing 1, reduce the size of the air conditioner indoor unit 100, and achieve miniaturization and weight reduction of the air conditioner indoor unit 100.

[0085] In some embodiments of the present invention, reference is made to... Figure 2 , Figure 5 , Figure 6 , Figure 8 , Figure 9 and Figure 11 The casing 1 has side air outlets 16 on both the left and right sides to make the appearance of the indoor unit 100 symmetrical and beautiful, and to make the air conditioner deliver air evenly in all directions of the room, thus ensuring the uniformity of the indoor temperature.

[0086] Among them, such as Figure 4 and Figure 5 As shown, each centrifugal impeller includes a centrifugal volute 301, which includes a volute tongue 302 and a diffuser section 303. The structure of the volute tongue 302 reduces wind resistance and airflow loss. The diffuser section 303 defines an outlet opening 32.

[0087] In the left-right direction, the diffuser section 303 includes a first diffuser wall 304 connected to the volute tongue 302 and a second diffuser wall 305 disposed opposite to the first diffuser wall 304. The second diffuser wall 305 extends obliquely toward the first diffuser wall 304 so that the second diffuser wall 305 can be tangent to the peripheral wall of the impeller 31 whose cross-section is circular. When the airflow passes through the intersection of the peripheral wall of the impeller 31 and the second diffuser wall 305, no airflow loss will occur, and the airflow can be converged at the air outlet 32 ​​under the guidance of the second diffuser wall 305.

[0088] According to the principle of the impeller 31, the air volume inside the impeller 31 is more concentrated in the second diffuser wall 305 opposite to the volute tongue 302. The airflow flows through the guide of the second diffuser wall 305 to the air outlet 32. In the left and right direction, the air outlet 32 ​​is set in the direction of the second diffuser wall 305 relative to the vertical center line of the casing 1, which can reduce the distance that the airflow travels at the second diffuser wall 305 and reduce the air volume loss.

[0089] Multiple centrifugal impellers are fastened together by ultrasonic welding. The length of the integrated impeller assembly 3 can be adjusted by adjusting the number of impellers 31, the length of the impellers 31, and the distance between the two impellers 31 to match indoor air conditioners of different heights.

[0090] In some embodiments of the present invention, such as Figure 12 As shown, the housing 1 includes a rear frame 11, a front frame 12 and a front panel 14. The rear frame 11 is provided with an air inlet 111. The front frame 12 is located on the front side of the rear frame 11. The front panel 14 is located on the front side of the front frame 12 and is provided with a front air outlet 15. The left and right sides of the front frame 12 are provided with side air outlets 16.

[0091] The rear frame 11 of the housing 1 defines a space for accommodating structures such as the impeller assembly 3 and the heat exchanger assembly 5. The front side of this space has an opening that communicates with the air outlet 32 ​​of the impeller assembly 3. The front frame 12 is located on the front side of the rear frame 11, closing the opening. The front frame 12 defines a first air duct space 101 and a second air duct space 102 for communicating with the air outlet 32 ​​and the air outlet.

[0092] The front panel 14 is located on the front side of the front frame 12, and the front panel 14 has a front air outlet 15 at a position corresponding to the outlet of the first air duct space 101. The front air outlet 15 can partially open the outlet of the first air duct space 101. Side air outlets 16 are provided on both sides of the front frame 12, and the side air outlets 16 communicate with both the first air duct space 101 and the second air duct space 102.

[0093] In some embodiments of the present invention, such as Figure 12As shown, the front frame 12 is formed as a frame structure with openings at the front and back and defining the air outlet space. Its rear opening is connected to multiple air outlet openings 32 of the impeller assembly 3, and the front opening is closed by the front panel 14.

[0094] Reference Figure 8 , Figure 11 and Figure 12 The front frame 12 is provided with two partition components 13 that are spaced apart vertically. The partition components 13 can divide the air duct space defined by the frame structure into multiple spaces to achieve the diversion of airflow inside the air conditioning indoor unit 100, so that the airflow flows along different paths and is sent out through the air outlets in different directions.

[0095] The two partition components 13 are arranged vertically and horizontally to divide the air duct space into three spaces: upper, middle and lower. The middle space, that is, the space between the two partition components 13, defines the second air duct space 102. The two spaces, one above the other, that is, the two spaces on the opposite side of the two partition components 13, are the first air duct space 101, which are connected to the upper air outlet 151 and the lower air outlet 152 respectively.

[0096] In some embodiments of the present invention, such as Figure 8 , Figure 11 and Figure 12 As shown, each partition assembly 13 includes two partition plates 131 arranged intersectingly. The upper partition plate 131 extends downward toward the side air outlet 16, and the lower partition plate 131 extends upward toward the side air outlet 16.

[0097] Specifically, the first air duct space 101 corresponding to the upper air outlet 151 is divided into multiple different spatial regions, including a first air duct region connected to the corresponding air outlet 32. The first air duct region is equipped with a switching element 2 and has outlets on both the upper and lower sides that can discharge air. It also includes a second air duct region connected to the upper outlet of the first air duct region and the outlet forms the upper air outlet 151. It also includes two third air duct regions connected to the lower outlet of the first air duct region and the outlet is connected to the side air outlet 16. The switching element 2 can control the air outlet 32 ​​within the first air duct region to connect to the upper outlet of the first air duct region or to the lower outlet of the first air duct region.

[0098] The first air duct space 101 corresponding to the lower air outlet 152 can be divided into multiple different spatial regions, including a first air duct region connected to the corresponding air outlet 32. The first air duct region is equipped with a switching element 2 and has outlets on both the upper and lower sides that can discharge air. It also includes a second air duct region connected to the lower outlet of the first air duct region and the outlet forms the lower air outlet 152. It also includes two third air duct regions connected to the upper outlet of the first air duct region and the outlet is connected to the side air outlet 16. The switching element 2 can control the air outlet 32 ​​in the first air duct region to connect to the upper outlet of the first air duct region or to the lower outlet of the first air duct region.

[0099] The two partition plates 131 corresponding to the upper partition component 13 extend towards the side air outlet 16 at an angle downwards, and the two partition plates 131 define two third air duct areas between themselves and the side wall of their respective front frame 12. The two partition plates 131 corresponding to the lower partition component 13 extend towards the side air outlet 16 at an angle upwards, and the two partition plates 131 define two third air duct areas between themselves and the side wall of their respective front frame 12.

[0100] When the air outlet 32 ​​is connected to the side air outlet 16, under the guidance of the switching element 2, the airflow flows upward or downward to the third air duct area. During the upward or downward flow, the airflow contacts the partition plate 131 and turns under the action of the partition plate 131. Under the guidance of the partition plate 131, the airflow flows to the left and right sides.

[0101] When the airflow in the first air duct space 101 flows toward the side air outlet 16, the separation component 13 can divide the airflow in the first air duct space 101, so that the airflow can be divided into two parts and flow toward the left and right air outlets respectively. In the process of the airflow flowing toward the side air outlet 16, the airflow is guided to avoid air volume loss.

[0102] The two partition plates 131 can be formed as straight plates or curved plates 21. When the partition plate 131 is formed as a curved plate 21, the partition plate 131 can be bent to the side away from the third air duct area to better reduce wind resistance.

[0103] In some embodiments of the present invention, the switching element 2 is rotatably disposed within the first air duct space 101 so as to control the flow direction of the airflow within the first air duct space 101 by controlling the rotation of the switching element 2.

[0104] Specifically, the switching component 2 can be selectively rotated to a position that closes the upper outlet of the first air duct area or the lower outlet of the first air duct area, so as to control the airflow in the first air duct area to flow to the second air duct area or to the third air duct area, thereby controlling the airflow to flow to the front air outlet 15 or the side air outlet 16.

[0105] In some embodiments, the switching member 2 rotates between a first position and a second position. When the switching member 2 is rotated to the first position, its upper edge abuts against the upper edge of the air outlet 32, and its lower edge abuts against the front panel 14, so as to guide the airflow below the air outlet 32. When the switching member 2 is rotated to the second position, its upper edge abuts against the front panel 14, and its lower edge abuts against the lower edge of the air outlet 32, so as to guide the airflow above the air outlet 32.

[0106] In some embodiments of the present invention, reference is made to... Figure 3 , Figure 7 , Figure 10 and Figure 12 The switching element 2 is formed as an arc-shaped plate 21 to guide airflow to the front air outlet 15 or the side air outlet 16. The arc-shaped plate 21, as the switching element 2, is used to switch the air duct within the first air duct space 101, and has several advantages. On the one hand, the arc-shaped plate 21 can reduce the space occupied by the switching element 2 within the first air duct space 101, thereby making the opening of the first air duct space 101 smaller, simplifying the structure of the air conditioner indoor unit 100, reducing the volume of the air conditioner indoor unit 100, and achieving the lightweighting of the air conditioner. On the other hand, as an air guiding structure, the arc-shaped plate 21 has less wind resistance when the airflow passes through, reducing the air volume loss when the airflow passes through, and ensuring the air delivery effect of the air conditioner indoor unit 100.

[0107] In some embodiments of the present invention, such as Figure 1 , Figure 2 , Figure 5 , Figure 6 , Figure 9 and Figure 11 As shown, side air outlets 16 are provided on both the left and right sides of the front air outlet 15, and the first air duct space 101 is connected to the side air outlets 16 on the left and right sides respectively. This is to make the appearance of the indoor unit 100 of the air conditioner symmetrical and aesthetically pleasing, and to ensure that the air conditioner delivers air evenly in all directions of the room, thus ensuring the uniformity of the indoor temperature.

[0108] In some embodiments of the present invention, reference is made to... Figure 8 , Figure 11 and Figure 12 A diverter plate 19 is provided in the first air duct space 101. A portion of the diverter plate 19 extends obliquely toward the side air outlet 16 on the left to guide the airflow to the side air outlet 16 on the left, and another portion of the diverter plate 19 extends obliquely toward the side air outlet 16 on the right to guide the airflow to the side air outlet 16 on the right.

[0109] When the air outlet 32 ​​is connected to the side air outlet 16, under the guidance of the switching element 2, the airflow flows upward or downward to the diverter plate 19. During the upward or downward flow, the airflow contacts the diverter plate 19 and the partition plate 131. Under the action of the diverter plate 19 and the partition plate 131, the airflow is diverted and split. Under the guidance of the diverter plate 19 and the partition plate 131, the airflow is divided into multiple branches and flows to the left and right sides respectively. Under the guidance of the diverter plate 19, each branch will flow out of the air conditioner indoor unit 100 through different height positions of the side air outlet 16.

[0110] The diverter plate 19 can not only divert airflow to make the air volume uniform in the vertical direction of the side air outlet 16, but also reduce the wind resistance in the first air duct space 101, reduce the air volume loss in the process of airflow to the side air outlet 16, and reduce the noise and energy consumption of the air conditioner.

[0111] In some embodiments of the present invention, the total opening area of ​​the front air outlet 15 is larger than the total opening area of ​​the side air outlet 16, so that the air conditioner indoor unit 100 can send more air to the front of the air conditioner indoor unit 100 and send cold or warm air to a place further away from the air conditioner indoor unit 100. This is beneficial for the air conditioner to control the indoor temperature and for the air conditioner to achieve rapid cooling or rapid heating.

[0112] In some embodiments of the present invention, combined with Figure 2 , Figure 6 , Figure 8 , Figure 9 and Figure 11 As shown, the side air outlet 16 is provided with a plurality of first air guides 17 arranged at intervals along the vertical direction. Each first air guide 17 is rotatable. By controlling the rotation of the first air guide 17, the air outlet direction of the side air outlet 16 can be controlled. In cooling mode, the side air outlet 16 can be controlled to blow air upwards. In heating mode, the side air outlet 16 can be controlled to blow air downwards. Controlling the side air outlet 16 to blow air in different directions in different modes can help improve the cooling or heating effect of the air conditioner indoor unit 100 and improve the user experience.

[0113] Furthermore, refer to Figure 2 , Figure 3 , Figure 6 , Figure 7 , Figure 9 , Figure 10 and Figure 12The front air outlet 15 is equipped with a second air guide 18. The rotation axis of the second air guide 18 extends in the left and right direction. The second air guide 18 can control the air outlet direction of the front air outlet 15. On the one hand, it avoids the airflow blowing directly on the human body, so that the user has a better user experience. On the other hand, the second air guide 18 can guide the airflow to the upper part of the room in the cooling mode, or guide the airflow to the lower part of the room in the heating mode, so as to improve the cooling or heating effect of the air conditioner and make the room temperature more uniform.

[0114] In some embodiments of the present invention, the indoor unit 100 of the air conditioner includes at least two cooling modes, specifically,

[0115] The indoor unit 100 of the air conditioner includes a first cooling mode and a second cooling mode:

[0116] In the first cooling mode, such as Figures 2-3 As shown, the upper switching component 2 connects the upper air outlet 151 with the air outlet 32, and the lower switching component 2 connects the lower air outlet 152 with the air outlet 32. The impeller assembly 3 operates at the first speed.

[0117] In the first cooling mode, the fan assembly 3 operates at the first speed. The fan assembly 3 rotates faster and can deliver a larger volume of cold air. Both the upper air outlet 151 and the lower air outlet 152 can deliver cold air to the outside. By utilizing the larger opening area and larger air volume of the upper air outlet 151 and the lower air outlet 152, cold air can be quickly delivered to the room, thereby achieving rapid cooling of the room by the air conditioner.

[0118] In the second cooling mode, such as Figures 6-8 As shown, the upper switching element 2 connects the upper air outlet 151 with the air outlet 32, and the lower switching element 2 connects the side air outlet 16 with the air outlet 32. The impeller assembly 3 operates at a second speed, while the first speed is higher than the second speed.

[0119] In the second cooling mode, the fan assembly 3 operates at a second speed. The speed of the fan assembly 3 is slower than that in the first cooling mode, which is more conducive to reducing the energy consumption of the indoor unit 100. In the second cooling mode, the air conditioner mainly sends air out through the upper air outlet 151 and the side air outlet 16, while the lower air outlet 152 does not send air out. On the one hand, this can avoid cold air blowing directly on the user and improve the user experience. On the other hand, by mainly using the upper air outlet 151 to send out cold air, more cold air can be concentrated in the upper part of the room, which is conducive to uniform indoor temperature and achieving uniform cooling.

[0120] After the user starts the cooling mode, the indoor unit 100 of the air conditioner will start cooling using either the first cooling mode or the second cooling mode. The user can select or switch between the first cooling mode and the second cooling mode through the control panel or remote control.

[0121] In other embodiments, the indoor unit 100 of the air conditioner includes a temperature sensor for detecting the indoor ambient temperature. The control module is communicatively connected to the temperature sensor and controls the indoor unit 100 to cool the room using a first cooling mode or a second cooling mode based on the indoor temperature data detected by the temperature sensor. When the indoor temperature is higher than a first preset temperature, the control module controls the indoor unit 100 to operate in the first cooling mode. When the indoor temperature is equal to or lower than the first preset temperature, the control module controls the indoor unit 100 to operate in the second cooling mode.

[0122] In some other embodiments, after the user selects the first cooling mode on the control panel or remote control, the control module controls the air conditioner indoor unit 100 to operate in the first cooling mode. In this mode, the temperature sensor detects the indoor temperature in real time. When the indoor temperature drops to the first preset temperature, the control module automatically controls the air conditioner indoor unit 100 to operate in the second cooling mode.

[0123] In some embodiments of the present invention, the indoor unit 100 of the air conditioner includes at least two heating modes, specifically,

[0124] The indoor unit 100 of the air conditioner includes a first heating mode and a second heating mode:

[0125] In the first heating mode, such as Figures 2-3 As shown, the upper switching component 2 connects the upper air outlet 151 with the air outlet 32, and the lower switching component 2 connects the lower air outlet 152 with the air outlet 32. The impeller assembly 3 operates at the third rotation speed.

[0126] In the first heating mode, the fan assembly 3 operates at the third speed. The fan assembly 3 rotates faster and can deliver a larger volume of hot air. Both the upper air outlet 151 and the lower air outlet 152 can deliver hot air to the outside. By utilizing the larger opening area and larger air volume of the upper air outlet 151 and the lower air outlet 152, hot air can be quickly delivered to the room, so as to achieve rapid heating of the room by the air conditioner.

[0127] In the second heating mode, such as Figures 9-11 As shown, the upper switching element 2 connects the side air outlet 16 with the air outlet 32, and the lower switching element 2 connects the lower air outlet 152 with the air outlet 32. The impeller assembly 3 operates at a fourth speed, which is higher than the third speed.

[0128] In the second heating mode, the fan assembly 3 operates at a fourth speed. The speed of the fan assembly 3 is slower than that in the first heating mode, which is more conducive to reducing the energy consumption of the indoor unit 100. In the second heating mode, the air conditioner mainly blows air out through the lower air outlet 152 and the side air outlet 16, while the upper air outlet 151 does not blow air out. On the one hand, this can avoid hot air blowing directly on the user and improve the user experience. On the other hand, by mainly using the lower air outlet 152 to blow hot air out, more hot air can be concentrated in the lower part of the room, which is conducive to uniform indoor temperature and uniform heating.

[0129] After the user starts the heating mode, the indoor unit 100 of the air conditioner will start heating using either the first heating mode or the second heating mode. The user can select or switch between the first heating mode and the second heating mode through the control panel or remote control.

[0130] In other embodiments, the indoor unit 100 of the air conditioner includes a temperature sensor for detecting the indoor ambient temperature. The control module is communicatively connected to the temperature sensor and controls the indoor unit 100 to heat the room using a first heating mode or a second heating mode based on the indoor temperature data detected by the temperature sensor. When the indoor temperature is lower than a second preset temperature, the control module controls the indoor unit 100 to operate in the first heating mode. When the indoor temperature is higher than or equal to the second preset temperature, the control module controls the indoor unit 100 to operate in the second heating mode.

[0131] In some other embodiments, after the user selects the first heating mode on the control panel or remote control, the control module controls the air conditioner indoor unit 100 to operate in the first heating mode. In this mode, the temperature sensor detects the indoor temperature in real time. When the indoor temperature rises to the second preset temperature, the control module automatically controls the air conditioner indoor unit 100 to operate in the second heating mode.

[0132] The air conditioner indoor unit 100 of the present invention is described below with reference to the accompanying drawings.

[0133] like Figure 12 As shown, the indoor unit 100 of the air conditioner includes: a casing 1, a fan assembly 3, and a heat exchanger assembly 5.

[0134] The impeller assembly 3 includes a drive motor located at the bottom, a shaft connected to the motor shaft of the drive motor, and four centrifugal fans coaxially mounted on the shaft. The four centrifugal fans, from top to bottom, include a first centrifugal fan located at the top, a second centrifugal fan located at the bottom, and two third centrifugal fans located in the middle.

[0135] Each centrifugal impeller includes a centrifugal volute 301, which includes a volute tongue 302 and a diffuser section 303. The structure of the volute tongue 302 reduces wind resistance and airflow loss, while the diffuser section 303 defines an outlet opening 32. The outlet opening 32 of the first centrifugal fan is the first outlet opening 32, the outlet opening 32 of the second centrifugal fan is the second outlet opening 32, and the outlet opening 32 of the third centrifugal fan is the third outlet opening 32.

[0136] In the left-right direction, the diffuser section 303 includes a first diffuser wall 304 connected to the volute tongue 302 and a second diffuser wall 305 disposed opposite to the first diffuser wall 304. The second diffuser wall 305 extends obliquely toward the first diffuser wall 304 so that the second diffuser wall 305 can be tangent to the peripheral wall of the impeller 31 whose cross-section is circular. When the airflow passes through the intersection of the peripheral wall of the impeller 31 and the second diffuser wall 305, no airflow loss will occur, and the airflow can be converged at the air outlet 32 ​​under the guidance of the second diffuser wall 305.

[0137] According to the principle of the impeller 31, the air volume inside the impeller 31 is more concentrated in the second diffuser wall 305 opposite to the volute tongue 302. The airflow flows through the guide of the second diffuser wall 305 to the air outlet 32. In the left and right direction, the air outlet 32 ​​is set in the direction of the second diffuser wall 305 relative to the vertical center line of the casing 1, which can reduce the distance that the airflow travels at the second diffuser wall 305 and reduce the air volume loss.

[0138] The housing 1 includes: a rear frame 11, a front frame 12, and a front panel 14.

[0139] The rear frame 11 of the housing 1 defines a space for accommodating structures such as the impeller assembly 3 and the heat exchanger assembly 5. The front side of the space has an opening. The impeller assembly 3 is located in the space. Multiple air outlets 32 of the impeller assembly 3 are oriented toward and connected to the opening. The heat exchanger assembly 5 is located between the impeller assembly 3 and the rear frame 11. The rear frame 11 has an air inlet 111 for the indoor air conditioning unit 100.

[0140] Driven by the impeller assembly 3, the airflow enters the indoor unit 100 of the air conditioner from the air inlet 111, passes through the heat exchanger assembly 5 and enters each impeller 31 of the impeller assembly 3, and is sent out through the air outlet 32 ​​of the impeller assembly 3.

[0141] The front frame 12 and the front panel 14 are located on the front side of the rear frame 11 and form the front air outlet 15 and the side air outlet 16 of the air conditioner indoor unit 100. The front frame 12 closes the opening of the space defined by the rear frame 11 and defines the first air duct space 101 and the second air duct space 102 for connecting the air outlet opening 32 and the air outlet.

[0142] Specifically, the front frame 12 is formed as a frame structure with openings at the front and rear and defining the air outlet space. Its rear opening is connected to multiple air outlet openings 32 of the impeller assembly 3, and the front opening is closed by the front panel 14.

[0143] The front frame 12 is provided with two partition components 13 that are spaced apart vertically. The partition components 13 can divide the air duct space defined by the frame structure into multiple spaces to achieve the diversion of airflow inside the air conditioning indoor unit 100, so that the airflow flows along different paths and is sent out through the air outlets in different directions.

[0144] The two partition components 13 are arranged vertically to divide the air duct space into three spaces: upper, middle and lower. The middle space, that is, the space between the two partition components 13, defines the second air duct space 102. The two spaces, one above the other, that is, the two spaces on the opposite side of the two partition components 13, are the first air duct space 101, which are respectively connected to the first air outlet 32 ​​and the second air outlet 32.

[0145] The first air duct space 101 includes multiple areas, such as a first air duct area connected to the corresponding air outlet 32, the first air duct area being provided with a switching element 2 and having outlets on both the upper and lower sides capable of airflow, a second air duct area connected to one of the outlets of the first air duct area and the outlet forming a front air outlet 15, and two third air duct areas connected to the other outlet of the first air duct area and the outlet being connected to the side air outlet 16.

[0146] The two partition plates 131 corresponding to the upper partition component 13 extend towards the side air outlet 16 at an angle downwards, and the two partition plates 131 define two third air duct areas between themselves and the side wall of their respective front frame 12. The two partition plates 131 corresponding to the lower partition component 13 extend towards the side air outlet 16 at an angle upwards, and the two partition plates 131 define two third air duct areas between themselves and the side wall of their respective front frame 12.

[0147] The arc-shaped plate 21 switching component 2 can be rotated to the position of closing the upper outlet of the first air duct area or closing the lower outlet of the first air duct area, so as to control the airflow in the first air duct area to flow to the second air duct area or to the third air duct area, thereby controlling the airflow to flow to the front air outlet 15 or the side air outlet 16.

[0148] The switching component 2 includes an arc plate 21, a swing arm 22, and a rotating shaft 23. Since the rotation center of the switching component 2 is located outside the arc plate 21 during rotation, the space occupied by the switching component 2 is reduced. By setting the swing arm 22 between the arc plate 21 and the rotating shaft 23, the state of the switching component 2 can be controlled by controlling the rotation of the rotating shaft 23 and thus controlling the swing of the arc plate 21.

[0149] In some embodiments, the switching member 2 rotates between a first position and a second position. When the switching member 2 is rotated to the first position, its upper edge abuts against the upper edge of the air outlet 32, and its lower edge abuts against the front panel 14, so as to guide the airflow below the air outlet 32. When the switching member 2 is rotated to the second position, its upper edge abuts against the front panel 14, and its lower edge abuts against the lower edge of the air outlet 32, so as to guide the airflow above the air outlet 32.

[0150] A diverter plate 19 is provided in the third air duct area. A portion of the diverter plate 19 extends obliquely toward the left side air outlet 16 to guide the airflow to the left side air outlet 16, and another portion of the diverter plate 19 extends obliquely toward the right side air outlet 16 to guide the airflow to the right side air outlet 16.

[0151] When the air outlet 32 ​​is connected to the side air outlet 16, under the guidance of the switching element 2, the airflow flows upward or downward to the diverter plate 19. During the upward or downward flow, the airflow contacts the diverter plate 19 and the partition plate 131. Under the action of the diverter plate 19 and the partition plate 131, the airflow is diverted and split. Under the guidance of the diverter plate 19 and the partition plate 131, the airflow is divided into multiple branches and flows to the left and right sides respectively. Under the guidance of the diverter plate 19, each branch will flow out of the air conditioner indoor unit 100 through different height positions of the side air outlet 16.

[0152] The front panel 14 is located on the front side of the front frame 12, and the front panel 14 has a front air outlet 15 at a position corresponding to the outlet of the first air duct space 101. The front air outlet 15 is provided with a movable panel 4 that can move vertically. The movable panel 4 can close the front air outlet 15 when the air conditioner is off, and move to the inside of the front panel 14 when the air conditioner is on to open the front air outlet 15.

[0153] The front air outlet 15 includes an upper air outlet 151 and a lower air outlet 152. The upper air outlet 151 is connected to the first air outlet 32 ​​through a first air duct space 101 located above the second air duct space 102, and the lower air outlet 152 is connected to the second air outlet 32 ​​through a first air duct space 101 located below the second air duct space 102.

[0154] The front air outlet 15 can partially open the outlet of the first air duct space 101. Side air outlets 16 are provided on both sides of the front frame 12, and the side air outlets 16 are connected to both the first air duct space 101 and the second air duct space 102. That is, the third air outlet 32 ​​is connected to the side air outlet 16 through the second air duct space 102.

[0155] The front air outlet 15 is provided with a second air guide 18. The rotation axis 23 of the second air guide 18 extends in the left and right direction. The second air guide 18 can control the air outlet direction of the front air outlet 15. The side air outlet 16 is provided with a plurality of first air guides 17 arranged at intervals in the vertical direction. Each first air guide 17 can rotate. By controlling the rotation of the first air guide 17, the air outlet direction of the side air outlet 16 can be controlled.

[0156] In the left-right direction, the side air outlets 16 are located to the left and right of the front air outlets 15. In the up-down direction, the upper air outlet 151 is located above the side air outlets 16, and the lower air outlet 152 is located below the side air outlets 16. The multiple air outlets together construct a multi-directional three-dimensional air outlet mode for the indoor air conditioner, giving the air conditioner a variety of air outlet modes, improving the user experience, and providing a structural basis for the indoor unit 100 to adopt different air supply modes in different modes. For example, in cooling mode, the indoor air conditioner can prioritize the upper air outlet 151 as the air outlet for outward air supply. Under this air supply mode, the air conditioner has a better cooling effect. In heating mode, the indoor air conditioner can prioritize the lower air outlet 152 as the air outlet for outward air supply. Under this air supply mode, the air conditioner has a better heating effect.

[0157] At the side air outlet 16, there is also an air guide plate 6. The air guide plate 6 opens the side air outlet 16 when the air conditioner is turned on and closes the side air outlet 16 when the air conditioner is turned off.

[0158] In some embodiments of the present invention, the air conditioner indoor unit 100 includes at least an open mode and a closed mode. Specifically, in the closed mode, the air guide plate 6 closes the side air outlet 16 and the movable panel 4 closes the front air outlet 15. In the open mode, the air guide plate 6 opens the side air outlet 16.

[0159] The indoor unit 100 of the air conditioner includes at least two heating modes. Specifically, the indoor unit 100 of the air conditioner includes a first heating mode and a second heating mode:

[0160] In the first heating mode, the upper switching component 2 rotates to the second position, so that the upper air outlet 151 is connected to the air outlet 32, and the lower switching component 2 rotates to the first position, so that the lower air outlet 152 is connected to the air outlet 32. The movable panel 4 opens the upper air outlet 151 and the lower air outlet 152. The second air guide 18 rotates to extend downward from the inside to the outside, and the first air guide 17 rotates to extend downward from the inside to the outside. The fan wheel assembly 3 operates at the third speed.

[0161] In the second heating mode, such as Figures 9-11As shown, the upper switching component 2 rotates to the first position, so that the side air outlet 16 is connected to the air outlet 32. The lower switching component 2 rotates to the first position, so that the lower air outlet 152 is connected to the air outlet 32. The movable panel 4 opens the lower air outlet 152 and closes the upper air outlet 151. The second air guide 18 rotates to extend horizontally from the inside to the outside. The first air guide 17 corresponding to the upper air outlet 151 rotates to extend upward from the inside to the outside. The first air guide 17 corresponding to the lower air outlet 152 rotates to extend downward from the inside to the outside. The impeller assembly 3 operates at a fourth speed, and the third speed is higher than the fourth speed.

[0162] After the user starts the heating mode, the indoor unit 100 of the air conditioner will start heating using either the first heating mode or the second heating mode. The user can select or switch between the first heating mode and the second heating mode through the control panel or remote control.

[0163] After the user selects the first heating mode on the control panel or remote control, the control module controls the air conditioner indoor unit 100 to operate in the first heating mode. In this mode, the temperature sensor detects the indoor temperature in real time. When the indoor temperature rises to the second preset temperature, the control module automatically controls the air conditioner indoor unit 100 to operate in the second heating mode.

[0164] The indoor unit 100 of the air conditioner includes at least two cooling modes. Specifically, the indoor unit 100 of the air conditioner includes a first cooling mode and a second cooling mode:

[0165] In the first cooling mode, the upper switching component 2 rotates to the second position, so that the upper air outlet 151 is connected to the air outlet 32, and the lower switching component 2 rotates to the first position, so that the lower air outlet 152 is connected to the air outlet 32. The movable panel 4 opens the upper air outlet 151 and the lower air outlet 152. The second air guide 18 rotates to extend horizontally from the inside to the outside. The first air guide 17 corresponding to the upper air outlet 151 rotates to extend upward from the inside to the outside. The first air guide 17 corresponding to the lower air outlet 152 rotates to extend downward from the inside to the outside. The fan wheel assembly 3 runs at the first speed.
