[0050] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the drawings, in which the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions from beginning to end. The embodiments described below by referring to the drawings are exemplary and are only used to explain the present invention and should not be construed as a limitation of the present invention.

[0051] Next, refer to Figures 1 - 16 to describe the air conditioner according to the embodiments of the present invention.

[0052] Refer to Figure 4 , Figure 6 and Figure 14, An air conditioner according to an embodiment of the present utility model includes a housing component 1, a heat exchanger assembly 2, and an air duct assembly 3. The housing component 1 includes a rear housing component 11 and a front housing component 12. The front housing component 12 is connected to the front side of the rear housing component 11. The front housing component 12 is formed with an air outlet 124 and an air inlet 125. The rear housing component 11 is formed with an air inlet 111. The heat exchanger assembly 2 is disposed inside the housing component 1 and the heat exchanger assembly 2 is located inside the rear housing component 11. The air duct assembly 3 is disposed inside the housing component 1 and the air duct assembly 3 is located between the heat exchanger assembly 2 and the air outlet 124. The air inlet 125 can facilitate the entry of normal-temperature air outside the housing component 1, and can also facilitate the air inside the housing component 1 to flow out through the air inlet 125 to the outside of the housing component 1. For example, when the air outlet 124 and the air inlet 125 are opened, the air inlet 125 can facilitate the entry of normal-temperature air outside the housing component 1 into the housing component 1, and after being mixed with the air that has exchanged heat inside the housing component 1, it is blown out through the air outlet 124 into the room; for another example, when the air outlet 124 is closed and the air inlet 125 is opened, the air inlet 125 can also facilitate the heat-exchanged air inside the housing component 1 to be blown out through the air inlet 125 into the room to cool or heat the room.

[0053] An air outlet passage 121 and an air inlet passage 122 are provided inside the front housing component 12. The air inlet passage 122 is located above the air outlet passage 121. A communication port 123 for communicating the air inlet passage 122 with the air outlet passage 121 is provided between the air inlet passage 122 and the air outlet passage 121. The air outlet 124 is opposite to and communicated with the air outlet passage 121. The air inlet 125 is located above the air outlet passage 121 and the air inlet 125 is communicated with the air inlet passage 122. An air inlet groove 1203 is formed on the inner wall of the air outlet passage 121, and the air inlet groove 1203 extends upward to the communication port 123. The air duct assembly 3 includes an air duct volute 31 and a blower wheel 32. An air duct 311 is provided inside the air duct volute 31. At least part of the blower wheel 32 is located inside the air duct 311. The air duct 311 communicates the air inlet 111 with the air outlet passage 121.

[0054] Among them, at least part of the blower wheel 32 being located inside the air duct 311 can include the following situations: For example, it can be that the entire blower wheel 32 is located inside the air duct 311; for another example, it can be that a part of the blower wheel 32 is located inside the air duct 311.

[0055] When the air conditioner is operating, the impeller 32 can drive the air flow to enter the rear housing component 11 through the air inlet 111 and flow towards the heat exchanger assembly 2. The air after heat exchange by the heat exchanger assembly 2 can flow through the air duct 311 in the air duct volute 31 towards the air outlet passage 121, and then be blown out to the room through the air outlet 124 to cool or heat the room. The air inlet 125 can introduce the normal-temperature air in the room into the air inlet passage 122, flow into the air outlet passage 121 through the communication port 123, mix with the air after heat exchange by the heat exchanger assembly 2 in the air outlet passage 121, and then be sent out through the air outlet 124, which can make the air flow at the air outlet 124 more comfortable, and thus improve the user experience.

[0056] When the air conditioner is operating and the air outlet 124 and the air inlet 125 are in the open state, the impeller 32 can drive the air flow to enter the rear housing component 11 through the air inlet 111 and flow towards the heat exchanger assembly 2. The air after heat exchange by the heat exchanger assembly 2 can flow through the air duct 311 in the air duct volute 31 towards the air outlet passage 121, and then be blown out to the room through the air outlet 124. At this time, there is a high-speed flowing gas flowing out at the air outlet 124, which can form a negative pressure area near the air outlet passage 121. For example, the air inlet passage 122 can be formed as a negative pressure area, so that the normal-temperature air outside the machine shell can be introduced into the air inlet passage 122 through the air inlet 125, flow into the air outlet passage 121 through the communication port 123, mix with the air after heat exchange by the heat exchanger assembly 2 in the air outlet passage 121, and then be sent out through the air outlet 124, so that the air blown out from the air outlet 124 will not be too cold or too hot, and the air flow blown out from the air outlet 124 is more comfortable.

[0057] Moreover, since the air guiding groove 1203 is formed on the inner wall of the air outlet passage 121 and the air guiding groove 1203 extends upward to the communication port 123, the air guiding groove 1203 can play a guiding role in the normal-temperature air flowing to the communication port 123, making the normal-temperature air flow into the air outlet passage 121 more smoothly through the air guiding groove 1203 to mix with the air after heat exchange in the air outlet passage 121. And the air guiding groove 1203 can guide the normal-temperature air to flow downward, which can increase the contact area between the normal-temperature air and the air after heat exchange in the air outlet passage 121, so that more normal-temperature air can be mixed with the air after heat exchange in the air outlet passage 121. Furthermore, the mixing effect of the normal-temperature air entering the air outlet passage 121 and the air after heat exchange can be more uniform, making the air flow at the air outlet 124 more comfortable, and further improving the user experience.

[0058] For example, when the air outlet 124 and the air induction port 125 are in the open state and the air conditioner is in the cooling mode, the impeller 32 can drive the air flow to enter the rear housing component 11 through the air inlet 111 and flow towards the heat exchanger assembly 2. The air after being heat-exchanged by the heat exchanger assembly 2 can flow towards the air outlet passage 121 through the air passage 311 in the air passage volute 31, and then be blown out to the room through the air outlet 124. At this time, there is a high-speed flowing gas flowing out at the air outlet 124, which can form a negative pressure area near the air outlet passage 121. For example, the air induction passage 122 can be formed into a negative pressure area. The normal-temperature air outside the housing can be introduced into the air induction passage 122 through the air induction port 125, flow into the air induction groove 1203 through the communication port 123, then flow into the air outlet passage 121, and be mixed with the relatively lower-temperature air that has been heat-exchanged by the heat exchanger assembly 2 in the air outlet passage 121, and then be sent out through the air outlet 124. The normal-temperature air introduced through the air induction port 125 and the air induction passage 122 is relatively higher in temperature than the air after heat exchange, and the air temperature after being heat-exchanged by the heat exchanger assembly 2 is relatively lower. The mixture of the relatively lower-temperature air after heat exchange and the introduced normal-temperature air can make the air flow temperature at the air outlet 124 more comfortable.

[0059] For another example, when the air outlet 124 and the air induction port 125 are in the open state and the air conditioner is in the heating mode, the impeller 32 can drive the air flow to enter the rear housing component 11 through the air inlet 111 and flow towards the heat exchanger assembly 2. The air after being heat-exchanged by the heat exchanger assembly 2 can flow towards the air outlet passage 121 through the air passage 311 in the air passage volute 31, and then be blown out to the room through the air outlet 124. At this time, there is a high-speed flowing gas flowing out at the air outlet 124, which can form a negative pressure area near the air outlet passage 121. For example, the air induction passage 122 can be formed into a negative pressure area. The normal-temperature air outside the housing component 1 can be introduced into the air induction passage 122 through the air induction port 125, flow into the air induction groove 1203 through the communication port 123, then flow into the air outlet passage 121, and be mixed with the air that has been heat-exchanged by the heat exchanger assembly 2 in the air outlet passage 121, and then be sent out through the air outlet 124. The normal-temperature air introduced through the air induction port 125 and the air induction passage 122 is relatively higher in temperature than the air after heat exchange, and the air temperature after being heat-exchanged by the heat exchange component is relatively lower. The mixture of the relatively lower-temperature air after heat exchange and the introduced normal-temperature air can make the air flow temperature at the air outlet 124 more comfortable.

[0060] For another example, when the air outlet 124 is in the closed state, the air inlet 125 is in the open state and the air conditioner is operating, the air wheel 32 can drive the air flow to enter the rear housing component 11 through the air inlet 111 and flow towards the heat exchanger assembly 2. The air after heat exchange by the heat exchanger assembly 2 can flow towards the air outlet passage 121 in the air duct volute 31 through the air duct 311 in the air duct volute 31. By connecting the air outlet passage 121 and the air guiding passage 122 through the connection port 123, the air in the air outlet passage 121 can flow into the air guiding passage 122 through the connection port 123, and then flow out to the room through the air inlet 125 to cool or heat the room. Since the air inlet 125 is located above the air outlet passage 121 and also above the air outlet 124, the position of the air outlet is relatively high, which can reduce the discomfort caused by direct blowing, thereby improving the user experience.

[0061] Since the front housing component 12 is formed with the air inlet 125 and the air inlet 125 is located above the air outlet passage 121, external normal-temperature air can be introduced, mixed with the heat-exchanged air and blown out through the air outlet 124, making the air flow temperature at the air outlet 124 more comfortable. And when the air outlet 124 is closed, the heat-exchanged air flow can be blown out from the relatively high-positioned air inlet 125, which can reduce the discomfort caused by direct blowing, improve the user experience, and while realizing the air mixing function of the air conditioner, the space in the room along the up-and-down direction can be fully utilized, the width of the air conditioner can be reduced, and thus the occupation of the space in the room in the horizontal direction can be reduced.

[0062] Optionally, the air outlets 124 can be two spaced left and right. The air outlet passage 121 includes an air outlet main passage 1208 and two air outlet branch passages 1209. The two air outlet branch passages 1209 are located on the downstream side of the air outlet main passage 1208. The air outlet main passage 1208 connects the air duct 311 and the air outlet branch passages 1209. The two air outlet branch passages 1209 respectively correspond to the two air outlets 124, and each air outlet branch passage 1209 connects the corresponding air outlet 124 and the air outlet main passage 1208.

[0063] For the air conditioner according to the embodiment of the present invention, through the provided air guiding passage 122 and the air inlet 125, external normal-temperature air can be introduced, mixed with the heat-exchanged air and blown out through the air outlet 124, which can make the air outlet of the air conditioner more comfortable. And through the provided air guiding groove 1203, it can play a guiding role in the normal-temperature air flowing to the connection port 123, which can make the mixing effect of the air flow in the air outlet passage 121 more uniform and make the air flow at the air outlet 124 more comfortable. And while realizing the air mixing function of the air conditioner, the space in the room along the up-and-down direction can be fully utilized, the width of the air conditioner can be reduced, and thus the occupation of the space in the room in the horizontal direction can be reduced.

[0064] Refer to Figure 5 、Figure 13 and Figure 16 , according to some embodiments of the present utility model, there are a plurality of air guiding grooves 1203. The plurality of air guiding grooves 1203 are arranged at intervals in the left - right direction. The plurality of air guiding grooves 1203 can enhance the guiding effect of the normal - temperature air flowing to the communication port 123, so that more normal - temperature air can flow downward into the air outlet passage 121 more smoothly through each air guiding groove 1203, fully mix with the air flow after heat exchange in the air outlet passage 121, and thus the mixing effect of the air flow in the air outlet passage 121 can be more uniform.

[0065] In the description of the present utility model, the meaning of "a plurality" is two or more.

[0066] Referring to Figures 13 - 15 , according to some embodiments of the present utility model, the ratio of the dimension of the air guiding groove 1203 extending in the up - down direction to the dimension of the air outlet passage 121 extending in the up - down direction is greater than 1 / 8. For example, the ratio of the dimension of the air guiding groove 1203 extending in the up - down direction to the dimension of the air outlet passage 121 in the up - down direction can be 1 / 7, 1 / 6, 1 / 5, 1 / 3, 1 / 2, etc. By making the ratio of the dimension of the air guiding groove 1203 extending in the up - down direction to the dimension of the air outlet passage 121 extending in the up - down direction greater than 1 / 8, it can be ensured that the normal - temperature air flowing to the communication port 123 can flow downward through the air guiding groove 1203 and mix fully with the air after heat exchange in the air outlet passage 121, so that the air outlet of the air conditioner is more comfortable.

[0067] Referring to Figures 13 - 15 , according to some embodiments of the present utility model, the ratio of the dimension of the air guiding groove 1203 extending in the up - down direction to the dimension of the air outlet passage 121 extending in the up - down direction is 1 / 6 - 1 / 2. For example, the ratio of the dimension of the air guiding groove 1203 extending in the up - down direction to the dimension of the air outlet passage 121 in the up - down direction can be 1 / 6, 1 / 5, 1 / 4, 1 / 3, 1 / 2, etc. By making the ratio of the dimension of the air guiding groove 1203 extending in the up - down direction to the dimension of the air outlet passage 121 extending in the up - down direction not less than 1 / 6, it can be ensured that the normal - temperature air flowing to the communication port 123 can flow downward through the air guiding groove 1203 and mix with the air after heat exchange in the air outlet passage 121, so that the air outlet of the air conditioner is more comfortable; by making the ratio of the dimension of the air guiding groove 1203 extending in the up - down direction to the dimension of the air outlet passage 121 extending in the up - down direction not greater than 1 / 2, while realizing the air mixing function of the air conditioner, it is convenient to optimize the internal layout of the air conditioner and avoid occupying too much space due to the ratio of the dimension of the air guiding groove 1203 extending in the up - down direction to the dimension of the air outlet passage 121 extending in the up - down direction being too large.

[0068] The ratio of the dimension of the air guiding groove 1203 extending in the up-down direction to the dimension of the air outlet passage 121 extending in the up-down direction is 1 / 6 to 1 / 2, which can ensure that the normal-temperature air flowing to the communication port 123 can be mixed with the heat-exchanged air in the air outlet passage 121 through the air guiding groove 1203 downward, so as to make the air outlet of the air conditioner more comfortable. At the same time of realizing the air mixing function of the air conditioner, it is convenient to optimize the layout inside the air conditioner.

[0069] Referring to Figure 4 and Figure 5 , according to some embodiments of the present invention, the open end of the air guiding groove 1203 facing the air outlet passage 121 is the air guiding opening 1204. The inner wall of the air guiding opening 1204 is connected with an air guiding baffle 1205. The air guiding baffle 1205 blocks a part of the air guiding opening 1204 and the air guiding baffle 1205 forms a part of the side wall of the air outlet passage 121. The air guiding baffle 1205 and the inner wall of the air guiding opening 1204 define an air outlet 1210 communicating the air guiding groove 1203 with the air outlet passage 121. The air guiding opening 1204 can facilitate the normal-temperature air in the air guiding groove 1203 to flow into the air outlet passage 121 to be mixed with the heat-exchanged air in the air outlet passage 121. The part of the air guiding opening 1204 blocked by the air guiding baffle 1205 can guide the normal-temperature air in the air guiding groove 1203, so that the normal-temperature air can flow into the air outlet passage 121 through the air outlet 1210 as much as possible to be mixed with the heat-exchanged air flow in the air outlet passage 121.

[0070] Referring to Figure 4 and Figure 5 , according to some embodiments of the present invention, in the direction of the air flow in the air outlet passage 121, the air guiding baffle 1205 is located on the upstream side of the air guiding opening 1204, so that the normal-temperature air can flow forward into the air outlet passage 121 through the air outlet 1210 as much as possible to be mixed with the heat-exchanged air flow in the air outlet passage 121, reducing or avoiding the possibility of the normal-temperature air flowing backward into the air duct 311, and enhancing the mixing effect of the normal-temperature air and the heat-exchanged air in the air outlet passage 121, thereby improving the comfort of the air flow at the air outlet 124.

[0071] Referring to Figure 4 and Figure 5, according to some embodiments of the present utility model, in the direction of the airflow in the air outlet passage 121, the size range of the air extraction port 1210 is 16 mm to 35 mm. For example, the size of the air extraction port 1210 can be 16 mm, 23 mm, 26 mm, 30 mm, 35 mm, etc. By making the size of the air extraction port 1210 not less than 16 mm, the normal temperature air in the air extraction groove 1203 can smoothly flow into the air outlet passage 121 through the air extraction port 1210; by making the size of the air extraction port 1210 not greater than 35 mm, the normal temperature air in the air extraction groove 1203 can flow forward into the air outlet passage 121 as much as possible, so as to ensure the mixing effect of the normal temperature air and the airflow after heat exchange in the air outlet passage 121, and reduce or avoid the normal temperature air in the air extraction groove 1203 flowing backward into the air duct 311 due to the too large size of the air extraction port 1210.

[0072] By making the size range of the air extraction port 1210 be 16 mm to 35 mm, the normal temperature air in the air extraction groove 1203 can smoothly flow into the air outlet passage 121 through the air extraction port 1210, so as to ensure the mixing effect of the normal temperature air and the airflow after heat exchange in the air outlet passage 121.

[0073] Refer to Figure 4 and Figure 5 , according to some embodiments of the present utility model, in the direction of the airflow in the air outlet passage 121, the size range of the air extraction baffle 1205 is 25 mm to 40 mm. For example, the size w1 of the air extraction baffle 1205 can be 25 mm, 28 mm, 30 mm, 36 mm, 40 mm, etc. By making the size w1 of the air extraction baffle 1205 not less than 25 mm, the normal temperature air in the air extraction groove 1203 can flow forward into the air outlet passage 121 through the air extraction port 1210 as much as possible, so as to ensure the mixing effect of the normal temperature air and the airflow after heat exchange in the air outlet passage 121, and reduce or avoid the normal temperature air in the air extraction groove 1203 flowing backward into the air duct 311 due to the too small size of the air extraction baffle 1205; by making the size w1 of the air extraction baffle 1205 not greater than 40 mm, the normal temperature air in the air extraction groove 1203 can smoothly flow into the air outlet passage 121 through the air extraction port 125.

[0074] By making the size range of the air extraction baffle 1205 be 25 mm to 40 mm, the normal temperature air in the air extraction groove 1203 can smoothly flow into the air outlet passage 121 through the air extraction port 1210, so as to ensure the mixing effect of the normal temperature air and the airflow after heat exchange in the air outlet passage 121, and reduce or avoid the normal temperature air in the air extraction groove 1203 flowing backward into the air duct 311 due to the too small size of the air extraction baffle 1205.

[0075] Refer to Figure 4 and Figure 5, according to some embodiments of the present utility model, in the direction of the airflow in the air outlet passage 121, the size range of the air outlet 1210 is 16 mm to 35 mm; and, the size w1 of the air guiding baffle 1205 ranges from 25 mm to 40 mm, which can enable the normal temperature air in the air guiding groove 1203 to smoothly flow into the air outlet passage 121 through the air outlet 1210, so as to ensure the mixing effect of the normal temperature air and the airflow after heat exchange in the air outlet passage 121, and reduce or avoid the normal temperature air in the air guiding groove 1203 from flowing backward into the air duct 311 due to the too small size of the air guiding baffle 1205 or the too large size of the air outlet 1210.

[0076] Refer to Figure 4 , Figure 5 and Figure 14 , according to some embodiments of the present utility model, the air outlet passage 121 includes a first side wall 1201 and a second side wall 1202 located on the left and right sides of the air outlet passage 121. Air guiding grooves 1203 are formed on both the first side wall 1201 and the second side wall 1202. In the direction of the airflow in the air outlet passage 121, the size w2 of the air outlet 1210 corresponding to the air guiding groove 1203 on the first side wall 1201 ranges from 16 mm to 26 mm, and the size w3 of the air outlet 1210 corresponding to the air guiding groove 1203 on the second side wall 1202 ranges from 25 mm to 35 mm. For example, the size w2 of the air outlet 1210 corresponding to the air guiding groove 1203 on the first side wall 1201 can be 16 mm, 17 mm, 20 mm, 23 mm, 26 mm, etc., and the size w3 of the air outlet 1210 corresponding to the air guiding groove 1203 on the second side wall 1202 can be 25 mm, 27 mm, 30 mm, 32 mm, 35 mm, etc.

[0077] By making the size w2 of the air outlet 1210 corresponding to the air guiding groove 1203 on the first side wall 1201 not less than 16 mm and the size w3 of the air outlet 1210 corresponding to the air guiding groove 1203 on the second side wall 1202 not less than 25 mm, the normal temperature air in the air guiding groove 1203 can smoothly flow into the air outlet passage 121 through the air outlet 1210; by making the size w2 of the air outlet 1210 corresponding to the air guiding groove 1203 on the first side wall 1201 not greater than 26 mm and the size w3 of the air outlet 1210 corresponding to the air guiding groove 1203 on the second side wall 1202 not greater than 35 mm, the normal temperature air in the air guiding groove 1203 can flow forward into the air outlet passage 121 as much as possible, so as to ensure the mixing effect of the normal temperature air and the airflow after heat exchange in the air outlet passage 121, and reduce or avoid the normal temperature air in the air guiding groove 1203 from flowing backward into the air duct 311 due to the too large size of the air outlet 1210.

[0078] The dimension w2 of the air outlet 1210 corresponding to the air guiding groove 1203 on the first side wall 1201 ranges from 16 mm to 26 mm, and the dimension w3 of the air outlet 1210 corresponding to the air guiding groove 1203 on the second side wall 1202 ranges from 25 mm to 35 mm. This can enable the normal-temperature air in the air guiding groove 1203 to smoothly flow into the air outlet passage 121 through the air outlet 1210, so as to ensure the mixing effect of the normal-temperature air and the air flow in the air outlet passage 121 after heat exchange.

[0079] Referring to Figures 14 - 16 , according to some embodiments of the present invention, there is a partition 1271 between the air guiding passage 122 and the air outlet passage 121. A communication port 123 is formed on the partition 1271 or the communication port 123 is defined between the partition 1271 and the inner wall of the air guiding passage 122. The partition 1271 can separate the air guiding passage 122 from the air outlet passage 121, so that the normal-temperature air in the air guiding passage 122 and the air flow in the air outlet passage 121 are relatively independent before mixing, reducing or avoiding the possibility that the air flow in the air outlet passage 121 after heat exchange by the heat exchanger enters the air guiding passage 122. And through the communication port 123 on the partition 1271 or the communication port 123 defined between the partition 1271 and the inner wall of the air guiding passage 122, it is convenient for the normal-temperature air in the air guiding passage 122 to enter the air outlet passage 121 to be mixed with the air in the air outlet passage 121 after heat exchange by the heat exchanger assembly 2, and then be discharged into the room through the air outlet 124.

[0080] Referring to Figure 5 , Figure 14 and Figure 15 , according to some embodiments of the present invention, the inner wall of the air outlet passage 121 includes a first inner wall 1206, and an air guiding groove 1203 is formed on the first inner wall 1206. The inner wall of the air guiding passage 122 includes a second inner wall 1207, and the second inner wall 1207 is connected to the upper side of the first inner wall 1206. The partition 1271 is spaced apart from the first inner wall 1206 to define a communication port 123 between the partition 1271 and the first inner wall 1206. An air guiding groove 1203 is formed on the first inner wall 1206, and the partition 1271 is spaced apart from the first inner wall 1206 to define a communication port 123 between the partition 1271 and the first inner wall 1206, which can enable the air guiding groove 1203 to communicate with the communication port 123, so that the normal-temperature air guided to the communication port 123 by the air guiding groove 1203 can flow downward into the air outlet passage 121, and be mixed more evenly with the air flow in the air outlet passage 121 after heat exchange, making the air flow at the air outlet 124 more comfortable.

[0081] Referring to Figure 5 , Figure 14 and Figure 15, according to some embodiments of the present utility model, the first inner wall 1206 includes a first side wall 1201 and a second side wall 1202 located on the left and right sides of the air outlet passage 121. Air guiding grooves 1203 are formed on both the first side wall 1201 and the second side wall 1202, which can increase the communication area between the air guiding grooves 1203 and the communication port 123, so that more normal temperature air flows into the air outlet passage 121 through the air guiding grooves 1203 on the first side wall 1201 and the second side wall 1202 and mixes with the air flow after heat exchange in the air outlet passage 121. Furthermore, the mixing effect of the air flow in the air outlet passage 121 can be made more uniform.

[0082] Refer to Figures 14 - 16 , according to some embodiments of the present utility model, an air guiding valve 1231 for opening and closing the communication port 123 is provided at the communication port 123. By controlling the opening or closing of the communication port 123 through the air guiding valve 1231, the intelligent control of the air guiding function of the air conditioner can be realized, which is beneficial to improving the user experience.

[0083] Refer to Figure 16 , according to some embodiments of the present utility model, the air guiding valve 1231 is rotatable to open and close the communication port 123. For example, by adjusting the rotation angle of the air guiding valve 1231, the flow direction of the air flow at the communication port 123 can be guided.

[0084] Refer to Figure 16 , according to some embodiments of the present utility model, the rotation axis of the air guiding valve 1231 extends in the left - right direction, and the air guiding valve 1231 rotates in the up - down direction to open and close the communication port 123.

[0085] Refer to Figures 14 - 16 , according to some embodiments of the present utility model, the motor for driving the air guiding valve 1231 is a valve plate motor 1233. The valve plate motor 1233 is installed on the front shell component 12 and the valve plate motor 1233 is located outside the air guiding passage 122. The valve plate motor 1233 is connected to the air guiding valve 1231. The connection between the valve plate motor 1233 and the air guiding valve 1231 can drive the air guiding valve 1231 to rotate to open and close the communication port 123. And by the valve plate motor 1233 being located outside the air guiding passage 122, the space inside the front shell component 12 can be fully utilized, avoiding the installation of the valve plate motor 1233 from occupying the space in the air guiding passage 122, so that the gas in the air guiding passage 122 can flow more smoothly.

[0086] Refer to Figures 14 - 16, according to some embodiments of the present utility model, a communication port 123 is defined between the partition 1271 and the inner wall of the air guiding channel 122. A first sealing rib 1221 is provided on the inner wall of the air guiding channel 122, and a second sealing rib 1232 is provided on the air guiding valve 1231. When the air guiding valve 1231 closes the communication port 123, the second sealing rib 1232 abuts against the upper surface of the first sealing rib 1221. The first sealing rib 1221 can enhance the overall structural strength of the front housing component 12, and the second sealing rib 1232 can enhance the overall structural strength of the air guiding valve 1231. When the air guiding valve 1231 closes the communication port 123 and the second sealing rib 1232 abuts against the upper surface of the first sealing rib 1221, the connection between the air guiding valve 1231 and the front housing component 12 can be simple and have strong stability. Moreover, when the communication port 123 is in the closed position, the second sealing rib 1232 and the first sealing rib 1221 are in abutting connection, which can enhance the sealing effect at the communication port 123 and reduce or avoid the possibility of the airflow after heat exchange in the air outlet channel 121 leaking through the communication port 123.

The first rear end 128 is located at the rear side of the air guiding channel 122 and the first rear end 128 is closed, which can close the rear side of the air guiding channel 122, prevent the normal temperature air in the air guiding channel 122 from flowing to the rear side of the front housing component 12 and mixing with the airflow after heat exchange in the air duct 311, reduce or avoid the possibility of the airflow after heat exchange in the air duct 311 flowing into the air guiding channel 122, and make the normal temperature air in the air guiding channel 122 flow through the communication port 123 to the air outlet channel 121 as much as possible to mix with the airflow after heat exchange in the air outlet channel 121, so that the airflow at the air outlet 124 is more comfortable. The second rear end 129 is located at the rear side of the air outlet channel 121 and the second rear end 129 is open, which can make the rear side of the air outlet channel 121 open, facilitate the connection between the air outlet channel 121 and the air duct 311, enable the airflow after heat exchange in the air duct 311 to flow smoothly into the air outlet channel 121, and then be discharged to the room through the air outlet 124.

For example, there are two air outlets 124 arranged at intervals left and right, and the two air outlets 124 can be respectively located on the left and right sides of the front panel 132. The rear side of the front air outlet frame 126 is open, the rear side of the rear air outlet frame 127 is open, and the front air outlet frame 126 and the rear air outlet frame 127 jointly define the air outlet channel 121, which can make the rear side of the air outlet channel 121 open, facilitating the connection of the air outlet channel 121 to the air duct 311, so that the airflow heated after heat exchange in the air duct 311 flows through the air outlet channel 121 to the air outlet 124.

[0095] Refer to Figure 15 and Figure 16, according to some embodiments of the present utility model, an installation opening 1272 is formed on one side of the rear air outlet frame 127 in the left-right direction. At least part of the installation opening 1272 corresponds to the air guiding channel 122 and the installation opening 1272 is communicated with the air guiding channel 122. A detachable air outlet frame side plate 1273 is covered at the installation opening 1272. The installation opening 1272 can facilitate the installation of the air guiding valve 1231 and the valve plate motor 1233 on the front shell component 12. By covering the detachable air outlet frame side plate 1273 at the installation opening 1272, it can facilitate the installation or disassembly of the air outlet frame side plate 1273 at the installation opening 1272, thereby facilitating the installation or disassembly of the air guiding valve 1231 and the valve plate motor 1233 on the front shell component 12 through the installation opening 1272; and, since the installation opening 1272 is communicated with the air guiding channel 122, by covering the air outlet frame side plate 1273 at the installation opening 1272, the installation opening 1272 can be made into a closed structure, which can reduce or avoid the possibility of the normal-temperature air in the air guiding channel 122 leaking through the installation opening 1272.

[0099] Refer to Figure 1 、 Figure 2 and Figure 4, according to some embodiments of the present utility model, the air inlet 125 is located directly above the air outlet 124, and the air conditioner further includes a wind deflector 4. The wind deflector 4 is used to open and close the air outlet 124 and the air inlet 125. The wind deflector 4 can guide the air flow flowing out through the air outlet 124 and the air flow flowing into or out of the air inlet 125. For example, the wind deflector 4 is rotatably provided at the air outlet 124 and the air inlet 125. By adjusting the rotation amplitude of the wind deflector 4, the air outlet 124 can be opened or closed, and the direction of the air flow at the air outlet 124 and the air inlet 125 can also be adjusted.

[0100] Referring to Figure 2 and Figure 6 , according to some embodiments of the present utility model, the wind deflector 4 includes a first wind deflector portion 41 and a second wind deflector portion 42. The second wind deflector portion 42 is connected to the upper side of the first wind deflector portion 41. The first wind deflector portion 41 is used to open and close the air outlet 124, and the second wind deflector portion 42 is used to open and close the air inlet 125. A plurality of ventilation holes are formed in both the first wind deflector portion 41 and the second wind deflector portion 42. The ventilation holes penetrate the wind deflector 4 along the thickness direction of the wind deflector 4. The air conditioner has a no-wind feeling mode. In the no-wind feeling mode, the wind deflector 4 closes the air outlet 124 and the air inlet 125. When the air conditioner is in the no-wind feeling mode, the wind deflector 4 is in the closed position, and the air flow enters the casing component 1 through the air inlet 111 and flows towards the heat exchanger assembly 2. The air flow after being heat-exchanged by the heat exchanger assembly 2 can be blown out through the ventilation holes on the wind deflector 4, which can make the air flow out of the air outlet 124 softer, thereby improving the user experience.

[0101] In addition, when the air conditioner is in the no-wind feeling mode, when the wind deflector 4 is in the closed position and the communication port 123 is in the open position, a part of the air flow in the air outlet passage 121 passes through the ventilation holes on the wind deflector 4 and is blown out into the room. Since the air pressure in the air outlet passage 121 is relatively high at this time, another part of the air flow in the air outlet passage 121 can also flow into the air inlet passage 122 through the communication port 123 and then be blown out through the air inlet 125 communicating with the air inlet passage 122, which can increase the air outlet area of the air conditioner in the no-wind feeling mode and quickly meet the required cooling / heating effect of the user, thereby further improving the user experience.

[0102] Optionally, there are two air outlets 124 arranged at intervals left and right, and there are two wind deflectors 4. The two wind deflectors 4 respectively correspond to the two air outlets 124. The air inlets 125 are located on the left and right sides of the air inlet passage 122. The left air inlet 125 is located directly above the left air outlet 124. The left wind deflector 4 is used to open and close the left air outlet 124 and the left air inlet 125. The right air inlet 125 is located directly above the right air outlet 124. The right wind deflector 4 is used to open and close the right air outlet 124 and the right air inlet 125.

[0110] An installation opening 1272 is formed on one side of the rear air outlet frame 127 in the left - right direction. At least a part of the installation opening 1272 corresponds to and communicates with the air guiding passage 122. A detachable air outlet frame side plate 1273 is provided at the installation opening 1272.

[0111] The inner wall of the air outlet passage 121 includes a first inner wall 1206. The first inner wall 1206 includes a first side wall 1201 and a second side wall 1202 on the left and right sides of the air outlet passage 121. Air guiding grooves 1203 are formed on both the first side wall 1201 and the second side wall 1202. The inner wall of the air guiding passage 122 includes a second inner wall 1207. The second inner wall 1207 is connected to the upper side of the first inner wall 1206. A first sealing rib 1221 is provided on the inner wall of the air guiding passage 122. There is a partition 1271 between the air guiding passage 122 and the air outlet passage 121. The partition 1271 is spaced apart from the first inner wall 1206 to define a communication port 123 between the partition 1271 and the first inner wall 1206. An air guiding valve 1231 for opening and closing the communication port 123 is provided at the communication port 123. The air guiding valve 1231 is rotatable, and the rotation axis of the air guiding valve 1231 extends in the left - right direction to open and close the communication port 123. A second sealing rib 1232 is provided on the air guiding valve 1231. When the air guiding valve 1231 closes the communication port 123, the second sealing rib 1232 abuts against the upper surface of the first sealing rib 1221. The motor for driving the air guiding valve 1231 is a valve plate motor 1233. The valve plate motor 1233 is installed on the front housing component 12 and is located outside the air guiding passage 122. The valve plate motor 1233 is connected to the air guiding valve 1231.

[0112] The air guiding groove 1203 extends upward to the communication port 123. The ratio of the dimension of the air guiding groove 1203 extending in the up-down direction to the dimension of the air outlet channel 121 extending in the up-down direction is 1 / 6 to 1 / 2. The open end of the air guiding groove 1203 facing the air outlet channel 121 is the air guiding opening 1204. An air guiding baffle 1205 is connected to the inner wall of the air guiding opening 1204. The air guiding baffle 1205 blocks a part of the air guiding opening 1204 and the air guiding baffle 1205 forms a part of the side wall of the air outlet channel 121. The air guiding baffle 1205 and the inner wall of the air guiding opening 1204 define an air outlet 1210 that communicates the air guiding groove 1203 with the air outlet channel 121. In the direction of the airflow in the air outlet channel 121, the air guiding baffle 1205 is located on the upstream side of the air guiding opening 1204. The dimension range of the air guiding baffle 1205 is 25 mm to 40 mm. The dimension range of the air outlet 1210 corresponding to the air guiding groove 1203 on the first side wall 1201 is 16 mm to 26 mm. The dimension range of the air outlet 1210 corresponding to the air guiding groove 1203 on the second side wall 1202 is 25 mm to 35 mm.

[0113] For example, when the air outlet 124 and the air guiding port 125 are in the open state and the air conditioner is in the cooling mode, the impeller 32 can drive the airflow to enter the rear housing component 11 through the air inlet 111 and flow towards the heat exchanger assembly 2. The air after being heat-exchanged by the heat exchanger assembly 2 can flow through the air duct 311 in the air duct volute 31 to the air outlet channel 121, and then be blown out of the air outlet 124 to the room. At this time, there is a high-speed flowing gas flowing out at the air outlet 124, and a negative pressure area can be formed near the air outlet channel 121. For example, the air guiding channel 122 can be formed as a negative pressure area. The normal-temperature air outside the housing can be introduced into the air guiding channel 122 through the air guiding port 125, flow into the air guiding groove 1203 through the communication port 123, then flow into the air outlet channel 121, and be mixed with the relatively low-temperature air that has been heat-exchanged by the heat exchanger assembly 2 in the air outlet channel 121, and then be sent out from the air outlet 124. The normal-temperature air introduced through the air guiding port 125 and the air guiding channel 122 is relatively high in temperature compared with the air after heat exchange. The air after being heat-exchanged by the heat exchanger assembly 2 is relatively low in temperature. The relatively low-temperature air after heat exchange and the introduced normal-temperature air can be mixed to make the airflow temperature at the air outlet 124 more comfortable.

[0114] For another example, when the air outlet 124 and the air induction port 125 are in the open state and the air conditioner is in the heating mode, the impeller 32 can drive the air flow to enter the rear housing component 11 through the air inlet 111 and flow towards the heat exchanger assembly 2. The air after being heat-exchanged by the heat exchanger assembly 2 can flow towards the air outlet passage 121 through the air passage 311 in the air duct volute 31, and then be blown out to the room through the air outlet 124. At this time, there is a high-speed flowing gas flowing out at the air outlet 124, which can form a negative pressure area near the air outlet passage 121. For example, the air induction passage 122 can be formed into a negative pressure area. The normal-temperature air outside the housing component 1 can be introduced into the air induction passage 122 through the air induction port 125, flow into the air induction groove 1203 through the communication port 123, then flow into the air outlet passage 121, and be mixed with the air after being heat-exchanged by the heat exchanger assembly 2 in the air outlet passage 121, and then be sent out through the air outlet 124. The normal-temperature air introduced through the air induction port 125 and the air induction passage 122 has a relatively higher temperature compared with the air after heat exchange. The temperature of the air after being heat-exchanged by the heat exchange component is relatively lower. The air with a lower temperature after heat exchange can be mixed with the introduced normal-temperature air to make the air flow temperature at the air outlet 124 more comfortable.

[0115] For another example, when the air outlet 124 is in the closed state, the air induction port 125 is in the open state and the air conditioner is operating, the impeller 32 can drive the air flow to enter the rear housing component 11 through the air inlet 111 and flow towards the heat exchanger assembly 2. The air after being heat-exchanged by the heat exchanger assembly 2 can flow towards the air outlet passage 121 through the air passage 311 in the air duct volute 31. The air outlet passage 121 and the air induction passage 122 are communicated through the communication port 123. The air in the air outlet passage 121 can flow into the air induction passage 122 through the communication port 123, and then flow out to the room through the air induction port 125 to cool or heat the room. Since the air induction port 125 is located above the air outlet passage 121 and also above the air outlet 124, the position of the air outlet is relatively high, which can reduce the discomfort caused by direct blowing, thereby improving the user experience.
