[0055] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0056] Reference below Figure 1-Figure 18 An air conditioner according to an embodiment of the present invention is described.

[0057] refer to Figure 1-Figure 3 The air conditioner according to the embodiment of the present invention comprises: a casing assembly 1, an upper deflector 2, a lower deflector 3 and a heat exchange and air supply assembly, wherein the upper deflector 2 and the lower deflector 3 are both arranged in an air outlet channel 11, and the heat exchange and air supply assembly is located on the upstream side of the air outlet channel 11.

[0058] The heat exchange and air supply assembly includes a heat exchanger component and a fan component. The heat exchanger component can be located on the upstream side of the fan component, and the fan component is used to drive the airflow. Optionally, the fan wheel of the fan component can be a crossflow fan wheel, and the axis of the crossflow fan wheel can extend in the up-down direction. There is one crossflow fan wheel, and the crossflow fan wheel and the main air outlet 132 are correspondingly arranged in the up-down direction. The crossflow fan wheel is located below the upper air outlet 131, and the crossflow fan wheel is located above the lower air outlet 133.

[0059] The casing assembly 1 is formed with an air outlet channel 11, an air inlet structure and an air outlet structure. The air outlet channel 11, the air inlet structure and the air outlet structure are connected to each other. When the fan component is working, the airflow outside the air conditioner is driven to enter the interior of the casing assembly 1 through the air inlet structure. After the airflow entering the casing assembly 1 exchanges heat with the heat exchanger component, it flows into the air outlet channel 11. The airflow flowing into the air outlet channel 11 is discharged into the room through the air outlet structure, thereby adjusting the indoor temperature.

[0060] The air outlet structure includes an upper air outlet 131, a main air outlet 132 and a lower air outlet 133 which are sequentially arranged from top to bottom, wherein there is at least one main air outlet 132, for example, there can be one main air outlet 132, or there can be multiple main air outlets 132. When there are multiple main air outlets 132, the multiple main air outlets 132 are arranged at intervals along the left and right directions. The upper air outlet 131, the main air outlet 132 and the lower air outlet 133 are all connected to the air outlet channel 11. For example, the upper air outlet 131 is arranged at the top of the housing component 1, the main air outlet 132 is arranged as two, and the two main air outlets 132 are respectively arranged on the left and right sides close to the housing component 1, and the lower air outlet 133 is arranged near the bottom of the housing component 1. The air conditioner can achieve multi-outlet air outlet through the upper air outlet 131, the main air outlet 132 and the lower air outlet 133, which is beneficial to promote indoor air flow and promote uniform indoor temperature so that the air conditioner can regulate the indoor air more effectively. At the same time, the air flow is sent out from multiple air outlets, and the air output is larger.

[0061] The upper deflector 2 is arranged at the upper part of the air outlet channel 11. The upper deflector 2 is located below the upper air outlet 131 and is adjacent to the upper air outlet 131. The upper deflector 2 is used to guide the airflow upward to the upper air outlet 131. The airflow flowing into the air outlet channel 11 can flow upward under the guiding action of the upper deflector 2. Under the guiding action of the upper deflector 2, more airflow in the air outlet channel 11 can flow upward to the upper air outlet 131 for discharge, which can increase the air outlet volume of the upper air outlet 131, thereby improving the comfort of the air conditioner in cooling mode.

[0062] The lower deflector 3 is arranged at the lower part of the air outlet channel 11. The lower deflector 3 is located above the lower air outlet 133 and the lower deflector 3 is adjacent to the lower air outlet 133. The lower deflector 3 is used to guide the airflow downward to the lower air outlet 133. The airflow flowing into the air outlet channel 11 can flow downward under the guiding action of the lower deflector 3. Under the guiding action of the lower deflector 3, more airflow in the air outlet channel 11 can flow downward to the lower air outlet 133 for discharge, which can increase the air outlet volume of the lower air outlet 133, thereby improving the comfort of the air conditioner in the heating mode.

[0063] According to the air conditioner of the embodiment of the present invention, an upper deflector 2 and a lower deflector 3 are provided, and the upper deflector 2 is located below and adjacent to the upper air outlet 131, and the lower deflector 3 is located above and adjacent to the lower air outlet 133. The upper deflector 2 is used to guide the airflow upward to the upper air outlet 131, which can increase the air outlet volume of the upper air outlet 131, thereby helping to improve the comfort of the air conditioner in the cooling mode; the lower deflector 3 is used to guide the airflow downward to the lower air outlet 133, which can increase the air outlet volume of the lower air outlet 133, thereby helping to improve the comfort of the air conditioner in the heating mode.

[0064] According to some embodiments of the present invention, reference Figure 2-Figure 12 The upper deflector 2 includes at least one upper deflector plate 21, and the upper deflector plate 21 is used to guide the airflow in the air outlet channel 11 upward. At least part of the upper deflector plate 21 extends upward, for example, part of the upper deflector plate 21 extends upward, and part of the upper deflector plate 21 can be formed to have an inclined surface or a curved surface; for example, the entire upper deflector plate 21 extends upward, and the upper deflector plate 21 can be formed to have an inclined surface or a curved surface. Optionally, the upper deflector 2 may include a plurality of upper deflectors 21, for example, the upper deflector plate 2 includes four deflectors. By providing the upper deflector plate 21, and making at least part of the upper deflector plate 21 extend upward, the airflow in the air outlet channel 11 flowing through the upper deflector plate 2 can flow to the upper air outlet 131 under the guidance of the upper deflector plate 21, and the air volume of the upper air outlet 131 can be increased, which is conducive to improving the comfort of the air conditioner in the cooling mode.

[0065] According to some optional embodiments of the present invention, the fan component includes a wind wheel, the tangent direction of the rotation direction of the wind wheel is the rotation tangent direction, the airflow flowing through the wind wheel is mainly sent out by the wind wheel along the rotation tangent direction, at least one upper guide plate 21 is opposite to the main air outlet 132 located in the rotation tangent direction, and the airflow flowing through the wind wheel is sent out in accordance with the rotation tangent direction and flows toward the main air outlet 132. When encountering the upper guide plate 21 opposite to the main air outlet 132, the airflow direction will be changed under the guidance of the upper guide plate 21, so that this part of the airflow is easy to flow upward to the upper air outlet 131. For example, the upper guide 2 includes a plurality of upper guide plates 21, and the plurality of upper guide plates 21 are opposite to the main air outlet 132 located in the rotation tangent direction. Due to the influence of the wind wheel operation mode, the airflow distribution of the airflow sent through the wind wheel in the left and right directions in the air conditioner is uneven. By making at least one guide plate opposite to the main air outlet 132 located in the direction of the rotation tangent, after the airflow passing through the wind wheel is sent out by the wind wheel, in the process of flowing toward the main air outlet 132, the airflow on the side with more air volume distribution encounters the upper guide plate 21 opposite to the main air outlet 132 and will change the airflow direction under the guidance of the upper guide plate 21, thereby making the airflow distribution through the upper air outlet 131 of the air conditioner more uniform.

[0066] According to some optional embodiments of the present invention, reference Figure 6 , Fig.10 , Fig.12 The upper guide plate 21 includes a first guide plate 211 and a second guide plate 212. The second guide plate 212 is connected to the upper side of the first guide plate 211. The first guide plate 211 extends in the horizontal direction, and the second guide plate 212 extends upward. Since the flow direction of the airflow sent out through the fan component is mainly to flow forward in the horizontal direction, by making the first guide plate 211 extend in the horizontal direction and the second guide plate 212 extend upward, the extension direction of the first guide plate 211 better conforms to the flow direction of the airflow sent out through the fan component, so that the airflow can flow more smoothly to the second guide plate 212, and flow to the upper air outlet 131 through the upward guiding effect of the second guide plate 212, thereby increasing the air volume at the upper air outlet 131 and optimizing the air conditioning effect of the air conditioner in the cooling mode.

[0067] According to some optional embodiments of the present invention, reference Figure 6 , Fig.10 , Fig.12The second guide plate 212 includes a first guide portion 2121 and a second guide portion 2122. The second guide portion 2122 is connected to the upper side of the first guide portion 2121. The first guide portion 2121 is connected between the first guide plate 211 and the second guide portion 2122. The first guide portion 2121 extends upwardly in an inclined direction, and the second guide portion 2122 extends in a vertical direction. By connecting the first guide portion 2121 between the first guide plate 211 and the second guide portion 2122 and extending upwardly in an inclined direction, the first guide portion 2121 can guide the airflow passing through the first guide plate 211 to flow to the second guide portion 2122 more smoothly; by extending the second guide portion 2122 in a vertical direction, the airflow passing through the second guide portion 2122 can be guided upwardly to the upper air outlet 131, so that the second guide plate 212 can better play the role of guiding the airflow upwardly.

[0068] According to some optional embodiments of the present invention, reference Figure 6 , Fig.10 , Fig.12 The first guide portion 2121 extends upward in an arc shape, and the airflow flows along the arc surface of the first guide portion 2121, with small wind resistance, so that the airflow flowing through the upper guide plate 21 flows more smoothly.

[0069] According to some optional embodiments of the present invention, reference Figure 2-Figure 12 The upper guide 2 includes a plurality of upper guide plates 21 arranged at intervals, and an upper guide channel 22 is defined between two adjacent upper guide plates 21. The airflow sent out by the fan component will flow into the upper guide channel 22 of the upper guide plate 21. Fig.12 The direction indicated by the middle arrow is the direction of airflow in the upper guide channel 22. The first guide plates 211 of the plurality of upper guide plates 21 are arranged at intervals in the vertical direction, and the second guide plates 212 of the plurality of upper guide plates 21 are arranged at intervals in the left-right direction. The upper guide channel 22 is thus formed into two parts, one arranged at intervals in the vertical direction and the other arranged at intervals in the left-right direction. The upper guide channel 22 is formed by arranging and defining the plurality of guide plates at intervals, so that the airflow can flow to the upper air outlet 131 through the upper guide channel 22.

Optionally, the lower deflector 3 includes a plurality of lower deflectors 31, for example, the lower deflector 3 includes two lower deflectors 31. By providing the lower deflector plate 31, and making at least part of the lower deflector plate 31 extend downwardly at an angle, the airflow in the air outlet channel 11 flowing through the lower deflector 3 can flow to the lower air outlet 133 under the guidance of the lower deflector plate 31, and the air volume of the lower air outlet 133 can be increased, which is conducive to improving the comfort of the air conditioner in the heating mode.

[0071] According to some optional embodiments of the present invention, reference Figure 5 , Fig.18 The guide surface of the lower guide plate 31 is a conical surface that is larger at the top and smaller at the bottom, which can increase the flow rate of the airflow at the lower guide plate 31, so that more airflow in the air outlet channel 11 flows downward to the lower air outlet 133 under the guidance of the lower guide plate 31.

[0072] According to some optional embodiments of the present invention, reference Figure 5 , Figure 13-Figure 16 The lower deflector 3 includes a plurality of lower deflectors 31 arranged along the circumference of the air outlet channel 11. By arranging the plurality of lower deflectors 31 along the circumference of the air outlet channel 11, it is convenient for the airflow in the air outlet channel 11 to flow through the lower deflectors 31, and the flow rate of the airflow in the air outlet channel 11 through the lower deflector 3 can be increased, thereby increasing the air volume at the lower air outlet 133.

[0073] According to some optional embodiments of the present invention, the upper deflector 2 includes a plurality of upper deflectors 21, and a deflector channel 22 is defined between the upper deflectors 21.

The air outlet frame 16 is connected to the front frame 15 by inserting a fastener through the air outlet frame 16 mounting hole and the front frame 15, and an air outlet channel 11 is defined between the air outlet frame 16 and the front frame 15. The upper deflector 2 can be installed on the air outlet frame 16, or the upper deflector 2 can be installed on the front frame 15, or the upper deflector 2 can be installed on both the air outlet frame 16 and the front frame 15; the lower deflector 3 can also be installed on the air outlet frame 16, or the deflector can be installed on the front frame 15, or the lower deflector 3 can be installed on both the air outlet frame 16 and the front frame 15. This arrangement can reasonably arrange the air outlet frame 16, the air outlet channel 11, and the upper deflector 2 and the lower deflector 3 in spatial position, so as to achieve the effect that the upper deflector 2 improves the comfort of the air conditioner in the cooling mode and the lower deflector 3 improves the comfort of the air conditioner in the heating mode.

[0077] According to some optional embodiments of the present invention, reference Figure 2The air outlet channel 11 includes an upper air outlet channel 111, a main air outlet channel 112 and a lower air outlet channel 113 arranged in sequence from top to bottom. The main air outlet channel 112 is opposite to the heat exchange and air supply assembly. The upper air outlet 131 is opposite to and communicates with the upper air outlet channel 111, the main air outlet 132 is opposite to and communicates with the main air outlet channel 112, and the lower air outlet 133 is opposite to and communicates with the lower air outlet channel 113. The airflow entering the air conditioner through the air inlet structure exchanges heat with the heat exchanger component of the heat exchange and air supply assembly, flows through the fan component and is sent out by the rotation of the fan component, and then flows into the air outlet channel 11. After entering the air outlet channel 11, part of the airflow will be sent to the room through the main air outlet channel 112 via the main air outlet 132; part of the airflow will enter the upper air outlet channel 111 from the main air outlet channel 112 through the upward guiding effect of the upper deflector 2, and then be sent to the room through the upper air outlet 131; and part of the airflow will enter the lower air outlet channel 113 from the main air outlet channel 112 through the downward guiding effect of the lower deflector 3, and then be sent to the room through the lower air outlet 133.

[0078] The lowermost end of the upper deflector 2 is not higher than the uppermost end of the main air outlet channel 112, for example, the lowermost end of the upper deflector 2 is flush with the uppermost end of the main air outlet channel 112, or the lowermost end of the lower deflector 3 is lower than the uppermost end of the main air outlet channel 112. The upper deflector 2 is used to guide the airflow in the main air outlet channel 112 upward to the upper air outlet channel 111, which can increase the flow rate of the airflow entering the upper air outlet channel 111 from the main air outlet channel 112. The uppermost end of the lower deflector 3 is not lower than the lowermost end of the main air outlet channel 112, for example, the uppermost end of the lower deflector 3 is flush with the lowermost end of the main air outlet channel 112, or the uppermost end of the lower deflector 3 is higher than the lowermost end of the main air outlet channel 112. The lower deflector 3 is used to guide the airflow in the main air outlet channel 112 downward to the lower air outlet channel 113, which can increase the flow rate of the airflow entering the lower air outlet channel 113 from the main air outlet channel 112. By ensuring that the lowermost end of the upper deflector 2 is not higher than the uppermost end of the main air outlet channel 112, the upper deflector 2 can guide more airflow in the main air outlet channel 112 to flow toward the upper air outlet 131; by ensuring that the uppermost end of the lower deflector 3 is not lower than the lowermost end of the main air outlet channel 112, the lower deflector 3 can guide more airflow in the main air outlet channel 112 to flow toward the lower air outlet 133.

[0079] According to some optional embodiments of the present invention, reference Figure 2, at least part of the upper deflector 2 is located in the main air outlet channel 112, for example, part of the upper deflector 2 is located in the main air outlet channel 112, and part of the upper deflector 2 is located in the upper air outlet channel 111; for example, the upper deflector 2 is entirely located in the main air outlet channel 112. At least part of the lower deflector 3 is located in the main air outlet channel 112, for example, part of the lower deflector 3 is located in the main air outlet channel 112, and part of the lower deflector 3 is located in the lower air outlet channel 113; for example, the lower deflector 3 is entirely located in the main air outlet channel 112. By making at least part of the upper deflector 2 located in the main air outlet channel 112 and at least part of the lower deflector 3 located in the main air outlet channel 112, the airflow that would otherwise be sent to the room through the main air outlet 132 from the main air outlet channel 112 can enter the upper air outlet channel 111 or the lower air outlet channel 113, and the flow rate of the airflow in the upper air outlet channel 111 and the lower air outlet channel 113 can be increased. Thus, the air volume of the main air outlet 132 can be reduced within a certain range, and the flow rate of the airflow flowing through the upper air outlet channel 111 and sent out through the upper air outlet 131 can be increased, which is conducive to improving the comfort of the air conditioner in the cooling mode; and the flow rate of the airflow flowing through the lower air outlet channel 113 and sent out through the lower air outlet 133 can be increased, which is conducive to improving the comfort of the air conditioner in the heating mode.

[0080] According to some optional embodiments of the present invention, reference Figure 3 In the horizontal direction, the upper deflector 2 is located in the middle of the main air outlet channel 112, so that the airflow in the main air outlet channel 112 can also flow to the upper air outlet channel 111 through both sides of the upper deflector 2, and then enter the room through the upper air outlet 131.

[0081] According to some optional embodiments of the present invention, reference Figure 2-Figure 4 The air outlet frame 16 includes a main air outlet frame 161, an upper air outlet frame 162 and a lower air outlet frame 163. The upper air outlet frame 162 and the lower air outlet frame 163 are respectively connected to the upper and lower sides of the main air outlet frame 161. The main air outlet frame 161 defines a main air outlet channel 112, the upper air outlet frame 162 defines an upper air outlet channel 111, and the lower air outlet frame 163 defines a lower air outlet channel 113. The upper deflector 2 is installed on the main air outlet frame 161, and the lower deflector 3 is installed on the front frame 15. By setting the main air outlet frame 161, the upper air outlet frame 162 and the lower air outlet frame 163, it is convenient to define the upper air outlet channel 111, the main air outlet channel 112 and the lower air outlet channel 113 from top to bottom in the air conditioner, so that the airflow can flow to the upper air outlet 131 through the upper air outlet channel 111, the airflow can flow to the main air outlet 132 through the main air outlet channel 112, and the airflow can also flow to the lower air outlet 133 through the lower air outlet channel 113; by installing the upper deflector 2 on the main air outlet frame 161, the upper deflector 2 can be at least partially located in the main air outlet channel 112.

[0082] According to some optional embodiments of the present invention, reference Figure 7-Figure 8 The upper deflector 2 is connected to the main air outlet frame 161 by fasteners. For example, a mounting column 23 is formed on the upper deflector 2, and a limiting column is formed on the main air outlet frame 161. Fasteners are inserted through the mounting column 23 and the limiting column to connect the upper deflector 2 to the main air outlet frame 161. The fastener connection is simple and convenient for disassembling and assembling the upper deflector 2.

[0083] According to some optional embodiments of the present invention, reference Figure 13-Figure 17 , the lower deflector 3 is snap-connected with the front frame 15. The lower deflector 3 is mounted on the front frame 15 by snap-connection, and the connection method is simple and convenient for assembly and disassembly.

[0084] According to some optional embodiments of the present invention, the bottom of the lower deflector 3 is snap-fitted with the front frame 15. For example, the bottom of the lower deflector 3 is provided with a limit slot 311 extending in the left-right direction, and the lower deflector 3 is snap-fitted to the front frame 15 in the left-right direction through the limit slot 311. The side of the lower deflector 3 is clamped between the front frame 15 and the lower air outlet frame 163 to limit the position of the lower deflector 3. For example, the lower deflector 3 is partially located between the front frame 15 and the lower air outlet frame 163, which can prevent the lower deflector 3 from being separated from the front frame 15, so that the lower deflector 3 is stably installed on the housing assembly 1.

[0085] According to some optional embodiments of the present invention, reference Figure 1-Figure 10 , there are two main air outlets 132 spaced apart from each other on the left and right sides, and the housing assembly 1 further includes a splitter plate 4, which is disposed between the front frame 15 and the air outlet frame 16 and between the two main air outlets 132, and the splitter plate 4 includes a left splitter portion 41 and a right splitter portion 42 arranged on the left and right sides. By providing the splitter plate 4, and making the splitter plate 4 include the left splitter portion 41 and the right splitter portion 42, the airflow flowing through the fan component and entering the air outlet channel 11 can flow toward the two air outlets respectively under the guidance of the left splitter portion 41 and the right splitter portion 42, so that both main air outlets 132 have air volume, and the air volume of the two main air outlets 132 is uniform.

[0086] According to some optional embodiments of the present invention, reference Fig. 9The top of the splitter plate 4 is formed with a first upper guide surface 44, which extends upwardly in an inclined direction from the back to the front; the bottom of the splitter plate 4 is formed with a first lower guide surface 45, which extends downwardly in an inclined direction from the back to the front. By providing the first upper guide surface 44 and the first lower guide surface 45, the first upper guide surface 44 can assist the upper deflector 2 to guide the airflow upward to the upper air outlet 131, which can increase the amount of airflow flowing upward, thereby further increasing the airflow of the upper air outlet 131, which is conducive to improving the comfort of the air conditioner in the cooling mode; the first lower guide surface 45 can assist the lower deflector 3 to guide the airflow downward to the lower air outlet 133, which can increase the amount of airflow flowing upward, thereby further increasing the airflow of the lower air outlet 133, thereby helping to improve the comfort of the air conditioner in the heating mode.

[0087] According to some optional embodiments of the present invention, reference Fig. 9 A second upper guide surface 18 is formed at the upper portion of the front frame 15. The second upper guide surface 18 extends upwardly in an inclined manner from the rear to the front, and the second upper guide surface 18 may be located above the first upper guide surface 44. By providing the second upper guide surface 18, the second upper guide surface 18 may assist the upper guide 2 and the first upper guide surface 44 in guiding the airflow upward to the upper air outlet 131, thereby increasing the amount of airflow flowing upward, thereby further increasing the airflow of the upper air outlet 131, thereby facilitating the improvement of the comfort of the air conditioner in the cooling mode.

[0088] According to some optional embodiments of the present invention, a wind guide plate for opening and closing the main air outlet 132 is provided at the main air outlet 132, and a plurality of air dispersion holes are formed on the wind guide plate. The air conditioner has a windless mode, in which the wind guide plate closes the main air outlet 132. By providing the wind guide plate, discomfort caused by the airflow entering the room through the air outlet can be avoided. In the windless mode, the airflow in the air conditioner can enter the room through the air dispersion holes of the wind guide plate, thereby improving the comfort of the air conditioner.

[0089] Optionally, when the air conditioner is in a cooling state, the main air outlet 132 is closed by the air guide plate, so that the air conditioner is adjusted to a windless cooling state. In the windless cooling state, the airflow in the main air outlet channel 112 that can enter the room through the main air outlet 132 is reduced. Under the guidance of the upper deflector 2, the airflow in the main air outlet channel 112 that can enter the room through the upper air outlet 131 is increased, which can improve the cooling comfort of the air conditioner.

[0090] According to some optional embodiments of the present invention, reference Figure 2The air conditioner further comprises a shutter mechanism 5, which is arranged in the air outlet channel 11 and between the upper deflector 2 and the lower deflector 3. The shutter mechanism 5 comprises a plurality of horizontal shutters 51 arranged at intervals in the up-down direction, and the horizontal shutters 51 can swing up and down. The air conditioner has a first working mode and a second working mode. In the first working mode, the air conditioner is in a cooling state and the horizontal shutters 51 are arranged to tilt upward. In the cooling state of the air conditioner, the horizontal shutters 51 are arranged to tilt upward to guide more airflow in the air outlet channel 11 to flow upward, increase the air volume of the upper air outlet 131, and make the airflow discharged through the upper air outlet 131 and the main air outlet 132 float as much as possible, so as to improve the cooling comfort of the air conditioner. In the second working mode, the air conditioner is in a heating state and the horizontal shutters 51 are arranged to tilt downward. In the heating mode of the air conditioner, the horizontal louver 51 is tilted downward to guide more air flow downward, thereby increasing the air volume of the lower air outlet 133. The air flow discharged through the lower air outlet 133 and the main air outlet 132 can be made to sink as much as possible, thereby improving the heating comfort of the air conditioner.

[0091] Optionally, in the first working mode, the air conditioner is in a windless cooling state and the horizontal louvers 51 are tilted upward so that the horizontal louvers 51 guide more air flow in the air outlet channel 11 to flow upward, further increasing the air outlet volume of the upper air outlet 131, so as to further improve the cooling comfort of the air conditioner.

In the cooling state, closing the lower air outlet 133 can increase the air volume of the upper air outlet 131 and the main air outlet 132 of the air conditioner, and can improve the cooling effect of the air conditioner. In the fourth working mode, the air conditioner is in a heating state, the upper switch door closes the upper air outlet 131, and the lower switch door opens the lower air outlet 133. In the heating state, closing the upper air outlet 131 can increase the air volume of the lower air outlet 133 and the main air outlet 132 of the air conditioner, thereby improving the heating effect of the air conditioner.

[0093] According to some optional embodiments of the present invention, the air conditioner includes a shutter structure, an upper switch door and a lower switch door. The shutter mechanism 5 is arranged in the air outlet channel 11 and between the upper deflector 2 and the lower deflector 3. The shutter mechanism 5 includes a plurality of horizontal shutters 51 arranged at intervals in the up-down direction, and the horizontal shutters 51 can swing up and down. The upper switch door is movably arranged at the upper end of the housing assembly 1 to open and close the upper air outlet 131, and the lower switch door is movably arranged at the lower end of the housing assembly 1 to open and close the lower air outlet 133. The air conditioner has a fifth working mode and a sixth working mode. In the fifth working mode, the air conditioner is in a cooling state, the upper switch door opens the upper air outlet 131 and the lower switch door closes the lower air outlet 133, and the horizontal shutter 51 is arranged to tilt upward. In the cooling state, closing the lower air outlet 133 and making the horizontal shutter 51 tilt upward can further increase the air volume of the upper air outlet 131 and the main air outlet 132, and can improve the cooling effect of the air conditioner. In the sixth working mode, the air conditioner is in the heating state, the upper switch door closes the upper air outlet 131 and the lower switch door opens the lower air outlet 133, and the horizontal louver 51 is tilted downward. In the heating state, closing the upper air outlet 131 and tilting the horizontal louver 51 downward can further increase the air volume of the lower air outlet 133 and the main air outlet 132, and can improve the heating effect of the air conditioner.

Fig.17As shown, the lowermost plane of the main air outlet frame in the vertical direction is the D3 plane, and the uppermost plane of the lower deflector 3 in the vertical direction is the D4 plane. When the lower deflector 3 is connected to the front frame 15, the D4 plane is flush with the D3 plane or the D4 plane is located above the D3 plane, so that the lower deflector 3 is at least partially located in the main air outlet channel 112.

[0102] Furthermore, the splitter plate 4 is provided with a first upper guide surface 44 and a first lower guide surface 45, and the front frame 15 is further provided with a second upper guide surface 18, which is located above the first upper guide surface 45. The first upper guide surface 44 and the second upper guide surface 18 are located at the front side of the upper guide 2, and are opposite to the upper guide channel 22 front and back. The first lower guide surface 45 is located at the front side of the lower guide 3, and is opposite to the lower guide channel 22 front and back.

[0103] In this embodiment, the air conditioner has a plurality of different working modes. The air conditioner includes a plurality of horizontal louvers 51 which are arranged at intervals in the vertical direction and can swing up and down. The air outlet direction of the air conditioner can be adjusted by tilting the horizontal louvers 51 upward or downward. The air conditioner includes an upper switch door and a lower switch door. The upper switch door is movably disposed at the upper end of the housing assembly 1 to open and close the upper air outlet 131. The lower switch door is movably disposed at the lower end of the housing assembly 1 to open and close the lower air outlet 133. The air conditioner can be placed in different working modes by opening or closing the upper air outlet 131 and the lower air outlet 133.

[0104] Next, the working mode of the air conditioner and the main flow states of the air flow in the air conditioner in order to achieve a good cooling effect or a good heating effect when the air conditioner is in a cooling or heating state will be described.

[0105] In the cooling state, the upper switch door is opened, the lower switch door is closed, and the horizontal louver 51 is adjusted to an upward tilted state, and the air conditioner is switched to the fifth working mode. At this time, the indoor airflow enters the interior of the air conditioner from the rear side of the air inlet structure, flows through the heat exchanger component and exchanges heat with the heat exchanger component to achieve a cooling effect, and then flows through the fan component and is sent to the air outlet channel 11 by the fan component. All the airflow sent by the fan component mainly enters the main air outlet channel 112 and the upper air outlet channel 111 under the upward guiding action of the horizontal louver 51. Part of the airflow entering the main air outlet channel 112 will flow out to the room through the main air outlet 132 in the main air outlet channel 112, and part of the airflow entering the main air outlet channel 112 will flow upward to the upper air outlet channel 111 through the main air outlet 132 in the main air outlet channel 112, and under the joint guiding action of the upper deflector 2 and the first upper guide surface 44 and the second upper guide surface 18, and then flow out to the room through the upper air outlet 131.

[0106] In the cooling state, the main air outlet 132 is closed by the air guide plate, so that the air conditioner is in a windless cooling state, and the upper switch door is opened, the lower switch door is closed, and the horizontal louver 51 is adjusted to an upward tilted state, and the air conditioner is switched to the fifth working mode. At this time, the indoor air enters the interior of the air conditioner from the rear side of the air inlet structure, flows through the heat exchanger component and exchanges heat with the heat exchanger component to achieve a cooling effect, and then flows through the fan component and is sent to the air outlet channel 11 by the fan component. All the airflow sent by the fan component mainly enters the main air outlet channel 112 and the upper air outlet channel 111 under the upward guidance of the horizontal louver 51. At this time, the airflow at the main air outlet 132 of the air conditioner needs to flow through the air scattering holes of the air guide plate to enter the room, and the airflow in the air outlet channel 11 that can flow out to the room through the main air outlet channel 112 and the main air outlet 132 is reduced, and the airflow in the main air outlet channel 112 that can flow into the upper air outlet channel 111 is increased. Therefore, under the joint guiding action of the upper deflector 2, the first upper deflector surface 44 and the second deflector surface, the airflow flowing into the upper air outlet channel 111 through the main air outlet channel 112 increases, thereby increasing the air volume of the upper air outlet 131. By increasing the air volume at the upper air outlet 131 through the upper deflector 2, the first upper deflector surface 44 and the second deflector surface, the effect of the reduction in the air volume of the main air outlet 132 on the indoor air temperature can be balanced to ensure the cooling effect in the windless mode.

[0107] In the heating mode, open the lower switch door, close the upper switch door, and adjust the horizontal louver 51 to a downward tilted state, and switch the air conditioner to the sixth working mode. At this time, the indoor air enters the interior of the air conditioner from the rear side of the air inlet structure, flows through the heat exchanger component and exchanges heat with the heat exchanger component to achieve the heating effect, then flows through the fan component and is sent to the air outlet channel 11 by the fan component. All the airflow sent by the fan component mainly enters the main air outlet channel 112 and the lower air outlet channel 113 under the downward guidance of the horizontal louver 51. Part of the airflow after entering the main air outlet channel 112 will flow out to the room through the main air outlet 132 in the main air outlet channel 112; part of the airflow will flow downward to the lower air outlet channel 113 through the main air outlet 132 under the joint guidance of the lower deflector 3 and the first lower guide surface 45 through the main air outlet channel 112, and then flow out to the room through the lower air outlet 133.
