[0044] The embodiments of the present invention are described in detail below, and examples of the embodiments 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.

[0045] Reference below Figure 1-Figure 16 The air conditioner 100 according to the embodiment of the present utility model is described. The air conditioner 100 here can be a window air conditioner, a wall-mounted air conditioner, etc.

[0046] like Figure 1-Figure 5 As shown, the air conditioner 100 according to the embodiment of the utility model has an air outlet channel 101 and an air outlet 104, the air outlet channel 101 and the air outlet 104 are connected, and the air outlet channel 101 and the air outlet 104 are both along a first direction (such as Figure 5 The air outlet channel 101 extends in a left-right direction as shown, and has two channel walls 102 . The two channel walls 102 are arranged opposite to each other in a first direction, and the air outlet 104 is located between the two channel walls 102 .

[0047] Among them, the air conditioner 100 has an air passage 105 at at least one end in the first direction, and one end of the air passage 105 is connected to the external space of the air conditioner 100. For example, one end of the air passage 105 is connected to the external space of the air conditioner 100 through a vent 106. The vent 106 can form a grille structure or a plurality of microporous structures. The other end of the air passage 105 is connected to the air outlet channel 101 through a connecting port 103, and the connecting port 103 is provided on the channel wall 102.

[0048] For example, the number of air passages 105 is one, and the air passage 105 can be arranged at one end of the air outlet channel 101 along the first direction; for another example, the number of air passages 105 can be two, and the two air passages 105 can be arranged at both ends of the air outlet channel 101 along the first direction; for another example, the number of air passages 105 can be more than two, and one end of the air outlet channel 101 along the first direction can be connected to at least one air passage 105, and the other end of the air outlet channel 101 along the first direction can be connected to the remaining multiple air passages 105.

[0049] The air outlet 104 can be opened and closed so that the air passage 105 forms an air inlet passage or an air outlet passage.

[0050] Specifically, Figure 8-Figure 10As shown, when the air outlet 104 is in an open state, the air passage 105 forms an air induction passage. In this state, high-speed gas flows out of the air outlet 104, and a local negative pressure area can be formed in the air outlet passage 101. The air outside the air conditioner 100 can be introduced into the air outlet passage 101 through the air passage 105, and mixed with the air in the air outlet passage 101, and finally sent out from the air outlet 104. By introducing external air, on the one hand, the outlet air temperature of the air outlet 104 changes gradually to avoid discomfort caused by sudden changes in the outlet air temperature, and on the other hand, the humidity of the air blown out of the air outlet 104 is moderate.

[0051] More specifically, when the air outlet 104 is in an open state and the air conditioner 100 is in a cooling mode, high-speed gas flows out of the air outlet 104, and a local negative pressure area can be formed in the air outlet channel 101. At this time, the air passage 105 can be used as an air duct, and the higher temperature air outside the air conditioner 100 can be introduced into the air outlet channel 101 through the air passage 105, and mixed with the lower temperature air in the air outlet channel 101, and then sent out from the air outlet 104, and the cycle continues.

[0052] Therefore, by introducing external air, on the one hand, the air outlet temperature of the air outlet 104 can be gradually reduced to avoid the discomfort caused by the sudden change of the air outlet temperature. On the other hand, the hot air blown out of the air outlet 104 will not be too dry, the humidity will be relatively high, and the air will be softer and more comfortable.

[0053] When the air outlet 104 is in an open state and the air conditioner 100 is in a heating mode, high-speed gas flows out of the air outlet 104, and a local negative pressure area can be formed in the air outlet channel 101. At this time, the air passage 105 can be used as an air duct, and the lower temperature air outside the air conditioner 100 can be introduced into the air outlet channel 101 through the air passage 105, and mixed with the higher temperature air in the air outlet channel 101, and then sent out from the air outlet 104, and the cycle continues.

[0054] Therefore, by introducing external air, on the one hand, the outlet air temperature of the air outlet 104 can be gradually increased to avoid discomfort caused by a sudden change in the outlet air temperature, and on the other hand, the humidity of the cool air blown out of the air outlet 104 is moderate.

[0055] like Figure 11-Figure 16As shown, when the air outlet 104 is closed, the air passage 105 can form an exhaust passage. In this state, a local high pressure area can be formed in the air outlet passage 101, and at least a part of the airflow in the air outlet passage 101 can be discharged from the air passage 105 to the outside of the air conditioner 100. In this way, at least part of the airflow can be discharged from at least one end of the air conditioner 100 along the first direction, and the air volume and air outlet direction of the air conditioner 100 are adjusted. It should be noted that the air outlet 104 is in a closed state, which can mean that the air outlet 104 is completely closed, or the air outlet 104 is partially closed, or the air outlet 104 is covered.

[0056] Of course, the air supply state of the air conditioner 100 is not limited to the above two types. During operation, the air conditioner 100 can also control the air outlet 104 to open and close periodically. During the switching process of the air outlet 104, the air duct 105 switches between positive and negative pressures due to the internal pressure of the air duct. Therefore, the air duct 105 can switch between the air induction function and the exhaust function, thereby making the air conditioner 100 form an intake and exhaust effect similar to breathing.

[0057] According to the air conditioner 100 of the embodiment of the utility model, by setting the wind passage 105 at at least one end of the air outlet channel 101, when the air outlet 104 is in the open state, high-speed gas flows out of the air outlet 104, and a negative pressure area can be formed at the position of the air outlet channel 101 close to the connecting port 103. The wind passage 105 forms an air induction channel, and the air outside the air conditioner 100 can be introduced into the air outlet channel 101 through the wind passage 105 for mixing, and then sent out from the air outlet 104, to a certain extent. The mixing effect of the airflow is improved, and the temperature and humidity of the airflow at the air outlet 104 are effectively fine-tuned, so that the temperature and humidity of the outlet airflow are more comfortable, and the user experience is improved; when the air outlet 104 is covered, a high-pressure area is formed in the air outlet channel 101 near the connecting port 103, so that the air passage 105 forms an exhaust channel, and at least a part of the airflow in the air outlet channel 101 can be discharged from the air passage 105 to the outside of the air conditioner 100, so that the air outlet direction and air volume can be adjusted to meet various usage requirements.

[0058] like Figure 5 As shown, according to some embodiments of the present invention, at least a portion of the air outlet channel 101 is formed as a gradually expanding section whose flow area gradually increases along the gas flow direction in the air outlet channel 101, and the connecting port 103 is provided on the wall of the gradually expanding section.

[0059] Therefore, by opening the connecting port 103 on the wall of the gradually expanding section of the air outlet duct 101, when the air outlet 104 is in an open state, a local negative pressure zone can be formed at the position of the air outlet duct 101 close to the connecting port 103, so that the air outside the air conditioner 100 can be more effectively introduced into the air outlet duct 101 through the air passage 105 for mixing, and to a certain extent, the temperature and humidity of the outlet air flow of the air outlet 104 are effectively fine-tuned, making the temperature and humidity of the outlet air flow more comfortable, softer, and the wind feeling is better.

[0060] like Figure 6 and Figure 7 As shown, according to some embodiments of the present invention, at least a portion of the channel wall 102 having the connecting opening 103 gradually deviates from the middle of the air outlet channel 101 in the first direction along a second direction, and the second direction is perpendicular to the first direction and extends from inside the air outlet channel 101 to outside the air outlet channel 101.

[0061] Specifically, in an embodiment where there is one air passage 105 and the communication opening 103 is only provided on the passage wall 102 corresponding to the air passage 105, the passage wall 102 at least partially gradually deviates from the middle of the air outlet passage 101 in the first direction along the second direction, and the other passage wall 102 can extend along the second direction. In an embodiment where there are two air passages 105 and the communication opening 103 is provided on both passage walls 102, the two passage walls 102 at least partially extend in a direction away from each other along the second direction.

[0062] Such an arrangement can form a size difference in the connecting port 103 in the first direction, and the wall of the air passage 105 close to the air outlet 104 can reduce the obstruction of the outlet air flow. When the outlet air flow passes through the connecting port 103, the air flow speed is faster and the air flow pressure is smaller, which can further increase the induced wind negative pressure, so that the external air can be more easily introduced into the air outlet channel 101 from the air passage 105, thereby improving the induced wind effect.

[0063] like Figure 6 and Figure 7 As shown, in some embodiments, in the second direction, the position of the communication opening 103 away from the air outlet 104 is the upstream portion 1031 , and the position of the communication opening 103 close to the air outlet 104 is the downstream portion 1032 .

[0064] Among them, the size of the upstream part 1031 of the connecting port 103 and the downstream part 1032 of the connecting port 103 in the first direction is greater than 3 mm; and / or, the size of the edge M of the upstream part 1031 and the air outlet 104 at the channel wall 102 in the first direction is greater than 5 mm.

[0065] Specifically, in an embodiment where the number of the air passages 105 is two and the two passage walls 102 are both provided with a communication opening 103, the air passage 101 is located at one end along the first direction (eg Figure 5 The upstream portion 1031 and the downstream portion 1032 of the connecting port 103 (shown at the left end) have a size L1 in the first direction, and the size L2 of the edge M of the upstream portion 1031 of the connecting port 103 and the air outlet 104 at the channel wall 102 in the first direction, and L2 is greater than L1.

[0066] The size L1 of the upstream portion 1031 and the downstream portion 1032 of the communication port 103 at one end of the air outlet channel 101 along the first direction in the first direction is greater than 3 mm, and the size L2 of the edge M of the upstream portion 1031 of the communication port 103 and the air outlet 104 at the channel wall 102 in the first direction is greater than 5 mm. For example, L1 can be 4 mm, L2 can be 6 mm; for another example, L1 can be 5 mm, L2 can be 6 mm, etc.

[0067] Located at the other end of the air outlet channel 101 along the first direction (such as Figure 5 The upstream portion 1031 and the downstream portion 1032 of the connecting port 103 (as shown in the right end) have a size L3 in the first direction, and the size L4 of the edge M of the upstream portion 1031 of the connecting port 103 and the air outlet 104 at the channel wall 102 in the first direction, and L4 is larger than L3.

[0068] The size L3 of the upstream portion 1031 and the downstream portion 1032 of the communication port 103 at the other end of the air outlet channel 101 along the first direction in the first direction is greater than 3 mm, and the size L4 of the edge M of the upstream portion 1031 of the communication port 103 and the air outlet 104 at the channel wall 102 in the first direction is greater than 5 mm. For example, L3 can be 4 mm, L4 can be 6 mm; for another example, L3 can be 5 mm, L4 can be 6 mm, etc.

[0069] It should be noted that the size L1 of the upstream portion 1031 and the downstream portion 1032 of the connecting port 103 located at one end of the air outlet channel 101 along the first direction, and the size L3 of the upstream portion 1031 and the downstream portion 1032 of the connecting port 103 located at the other end of the air outlet channel 101 along the first direction in the first direction may be equal or unequal.

[0070] The dimension L2 in the first direction of the upstream portion 1031 of the connecting port 103 located at one end of the air outlet channel 101 along the first direction and the edge M of the air outlet 104 at the corresponding channel wall 102, and the dimension L4 in the first direction of the upstream portion 1031 of the connecting port 103 located at the other end of the air outlet channel 101 along the first direction and the edge M of the air outlet 104 at the corresponding channel wall 102 may be equal or unequal.

[0071] In the above technical solution, by limiting the connecting port 103 to meet the above parameter range, the air flow velocity can be faster and the air flow pressure can be smaller when passing through the connecting port 103, and the induced air negative pressure can be further increased, so that the external air can be more easily introduced into the air outlet channel 101 from the air passage 105, thereby improving the induced air effect.

[0072] According to different design requirements of the air conditioner 100 , the channel wall 102 of the air outlet channel 101 may be configured as, but not limited to, a flat surface or a curved surface (eg, a curved surface) and the like.

[0073] In some embodiments, the angle between the plane where the communication opening 103 is located or the tangent plane of the arc surface where the communication opening 103 is located and the plane perpendicular to the first direction is less than 45°. In some examples, α is 3°-25°.

[0074] For example, at one end of the air outlet channel 101 along the first direction (such as Figure 5 The angle α1 between the plane where the connecting opening 103 is located and the plane perpendicular to the first direction can be 3°, 5°, 10°, 15°, or 20°; the angle α1 between the plane where the connecting opening 103 is located and the plane perpendicular to the first direction can be 3°, 5°, 10°, 15°, or 20°; Figure 5 The angle α2 between the tangent plane of the arc surface where the communicating port 103 is located and the plane perpendicular to the first direction can be 5°, 8°, 15°, 20°, or 25°, and α1 and α2 can be equal or unequal.

[0075] It is understandable that if the angle between the plane where the connecting port 103 is located or the section of the arc surface where the connecting port 103 is located and the plane perpendicular to the first direction is too large or too small, it will affect the air induction effect. In the above technical solution, the angle between the plane where the connecting port 103 is located or the section of the arc surface where the connecting port 103 is located and the plane perpendicular to the first direction satisfies the above parameter range, so that the air flow velocity is faster and the air flow pressure is smaller when passing through the connecting port 103, and the air induction negative pressure can be further increased, so that the external air can be more easily introduced into the air outlet channel 101 from the air passage 105, and the air flow in the air outlet channel 101 can be prevented from flowing back to the connecting port 103, thereby ensuring the air induction effect of the air induction channel.

[0076] like Figure 8-Figure 10 , Figure 14-16As shown, in some embodiments, the air outlet 104 is located at the front lower portion of the air conditioner 100, the first direction extends along the left-right direction, and the second direction extends from top to bottom.

[0077] When the air outlet 104 is in an open state, the effect of air outlet at the front lower part and air induction on the left and right sides can be formed, which can improve the uniformity of air flow mixing and the mixing effect of the air flow in the air outlet channel 101, so that the temperature and humidity of the air outlet airflow from the air outlet 104 are relatively uniform. When the air outlet 104 is in a covered state, the effect of exhausting air on at least the left and right sides can be formed, and the air outlet direction of the air volume of the air conditioner 100 can be adjusted.

[0078] According to some specific embodiments of the present invention, the number of the air passages 105 is at least two, at least two air passages 105 are arranged in the first direction, and the air outlet channel 101 is connected between the two air passages 105 .

[0079] In the above technical solution, by setting two air passages 105, when the air outlet 104 is in an open state, the amount of air mixed can be increased, the humidity and temperature regulation effect of the outlet air flow can be improved, and a better wind feeling experience can be brought. The two air passages 105 are located at the two ends of the air outlet channel 101 along the first direction, and can mix air at the two ends of the air outlet channel 101, thereby forming an effect of middle air outlet and two-side air induction, which can improve the uniformity of air flow mixing, improve the mixing effect of the air flow in the air outlet channel 101, and make the temperature and humidity of the outlet air flow of the air outlet 104 relatively uniform. When the air outlet 104 is in a covered state, the effect of exhausting at least two sides can be formed, and the air outlet direction of the air volume of the air conditioner 100 can be adjusted.

[0080] like Figure 8 and Fig. 9 As shown, according to some specific embodiments of the utility model, the air conditioner 100 includes a casing 11, an air duct component 12, a fan assembly 13 and a heat exchanger 14, the air duct component 12 is arranged in the casing 11, and the air duct component 12 includes a volute tongue 121, the air duct component 12 defines an air outlet channel 101, and the air outlet channel 101 is located downstream of the volute tongue 121 in the gas flow direction, the fan assembly 13 and the heat exchanger 14 are arranged in the casing 11, and the rotation axis of the fan assembly 13 extends along the first direction.

[0081] When the air conditioner 100 is working, the wind wheel 131 can drive the air in the external space to flow through the heat exchanger 14 through the air inlet 107. When the heat exchanger 14 is working, it can exchange heat with the passing air to form hot air or cold air. The airflow after heat exchange can be blown out through the air outlet channel 101.

[0082] like Figure 5As shown, in some embodiments, at least two wind passages 105 include a first wind passage 1051 and a second wind passage 1052, the first wind passage 1051 and the second wind passage 1052 are arranged in a first direction, and the air outlet channel 101 is connected between the first wind passage 1051 and the second wind passage 1052.

[0083] Among them, the first air passage 1051 is set away from the motor 132 of the fan assembly 13 and the second air passage 1052 is set close to the motor 132. The first air passage 1051 and the second air passage 1052 both extend along the first direction. In the first direction, the size of the first air passage 1051 is smaller than the size of the second air passage 1052.

[0084] Since the motor 132 of the fan assembly 13 is located at one axial end of the wind wheel 131, the setting position of the wind wheel 131 is not centered and symmetrical in the casing 11. Therefore, by limiting the second air passage 1052 and the motor 132 to be located at the same end of the wind wheel 131, and the size of the second air passage 1052 is larger than that of the first air passage 1051, the space utilization rate in the casing 11 can be improved, and the volume of the second air passage 1052 can be increased, which is beneficial to improving the wind-inducing effect of the second air passage 1052.

[0085] like Figure 1-Figure 3 , Figure 9-11 , Fig.15 and Fig.16 As shown, in some embodiments, the air conditioner 100 further includes a panel 15 , which is movable relative to the casing 11 , and the panel 15 is used to open and close the air outlet 104 .

[0086] Among them, the panel 15 can be away from the casing 11 and a guide air duct 151 is formed between the casing 11. The guide air duct 151 connects the air outlet 104 and the first air dispersion hole 152 on the panel 15. At least part of the airflow discharged from the air outlet 104 can enter the guide air duct 151, so that part of the wind energy is blown out from the guide air duct 151 or from the first air dispersion hole 152 of the panel 15, thereby improving the windless air outlet effect.

[0087] In the above technical solution, the panel 15 can play the role of closing the air outlet 104. When the air conditioner 100 is stopped, the panel 15 covers the air outlet 104 (see Figure 1 ); When the air conditioner 100 is working, the panel 15 can be moved to open the air outlet 104 (see Figure 2 and Fig.11), and the panel 15 can form a guide air duct 151 with the housing 11, which can guide the airflow in the windless mode to improve the windless experience. It can be seen that the panel 15 can achieve multiple uses, reduce the number of parts, reduce costs, and also help reduce assembly steps and improve assembly efficiency.

[0088] The first air dispersion holes 152 are arranged in an array on the panel 15. The first air dispersion holes 152 can be arranged in at least one row on the panel 15, and each row includes a plurality of first air dispersion holes 152. Exemplarily, the first air dispersion holes 152 are arranged in a row on the panel 15, and a plurality of the first air dispersion holes 152 in the row are arranged along the length direction of the panel 15 (the left and right direction in the figure and the drawing); or, the first air dispersion holes 152 are arranged in multiple rows on the panel 15, and a plurality of the first air dispersion holes 152 in each row are arranged along the length direction of the panel 15 (the left and right direction in the figure and the drawing).

[0089] In the above technical solution, the first air dispersion holes 152 arranged in an array can form a microporous structure on the panel 15. When the wind blown out of the air outlet 104 passes through the panel 15, the wind can be dispersed by the first air dispersion holes 152 arranged in an array to prevent the wind from blowing directly on the user, which is conducive to achieving windless air outlet.

[0090] like Figure 14-16 As shown, in some examples, the air conditioner 100 further includes an air guide assembly, which includes an air guide plate 16 , which is movably disposed in the air outlet channel 101 and extends along a first direction, and the air guide plate 16 is provided with a second air dispersion hole 161 .

[0091] Therefore, by setting up a movable air guide plate 16, the corresponding air outlet 104 can be opened and closed using the air guide plate 16 with a simpler structure and lower cost, and the air guiding effect can also be achieved, so that a variety of air supply states can be combined with the position state of the panel 15, thereby increasing the function of the air conditioner 100 and meeting different usage requirements.

[0092] The second air dispersion holes 161 are arranged in an array on the air guide plate 16. The second air dispersion holes 161 can be arranged in at least one row on the air guide plate 16, and each row includes a plurality of second air dispersion holes 161. Exemplarily, the second air dispersion holes 161 are arranged in a row on the air guide plate 16, and a plurality of second air dispersion holes 161 are arranged in the row along the length direction of the air guide plate 16 (the left and right direction as shown in the figure); or, the second air dispersion holes 161 are arranged in a plurality of rows on the air guide plate 16, and a plurality of second air dispersion holes 161 in each row are arranged along the length direction of the air guide plate 16.

[0093] It can be understood that the wind guide plate 16 can guide the wind blown out of the air outlet 104 to deviate from the user, and prevent the wind blown out of the air outlet 104 from blowing directly at the user. For example, the wind guide plate 16 can guide the wind to the guide air duct 151, so that part of the wind can be blown out from the guide air duct 151 or from the first wind dispersion holes 152 of the panel 15. Secondly, the second wind dispersion holes 161 arranged in an array on the wind guide plate 16 can play a role in breaking up the wind, and can prevent the wind from blowing directly at the user while allowing the wind to slowly diffuse to the front of the user, thereby achieving windless wind outlet facing the user. In other words, the wind guide plate 16 and the second wind dispersion holes 161 thereon, as well as the panel 15 and the first wind dispersion holes 152 thereon cooperate with each other to enhance the windless wind outlet effect.

[0094] In some specific examples, the air conditioner 100 has a first air supply mode and a second air supply mode.

[0095] like Figure 8-Figure 10 As shown, in the first air supply mode, the air guide plate 16 and the panel 15 open the air outlet 104 so that the air passage 105 forms an air induction passage.

[0096] Specifically, in this state, the wind speed in the air outlet channel 101 is generally high. Since the housing 11 has the air passage 105, when the wind passes through the air passage 105, due to the high wind speed, the pressure in the air outlet channel 101 is relatively small compared to the pressure in the air passage 105, so a negative pressure area is formed in the air outlet channel 101, and the air in the external environment can enter the air outlet channel 101 along the air passage 105, and be mixed with the hot air or cold air and blown out from the air outlet 104. The air introduced from the external environment can better adjust the temperature and humidity of the wind at the air outlet 104, improve the comfort of the air flow, and help to achieve softer air output and better wind feeling.

[0097] like Figure 14-16 As shown, in the second air supply mode, the panel 15 is away from the housing 11 and forms a guide air duct 151 , and the air guide plate 16 and the panel 15 cover the air outlet 104 so that the air passage 105 forms an exhaust passage.

[0098] Specifically, in this state, the panel 15 moves away from the housing 11 to form the guide air duct 151, and the air guide plate 16 moves to the set position. When the air guide plate 16 is in the set position, the air guide plate 16 forms an angle with the air outlet direction of the air outlet channel 101, which can play a wind blocking role and prevent the wind from the air outlet 104 from blowing directly to the user. When the air outlet 104 discharges air, the wind speed is relatively small and the air discharge is relatively slow, so that a local high pressure is formed in the air outlet channel 101, so that a part of the air flow in the air outlet channel 101 is dispersed and blown out from the second air dispersion hole 161 of the air guide plate 16, and another part flows to the guide air duct 151 under the guidance of the air guide plate 16, and is dispersed and blown out from the first air dispersion hole 152 of the panel 15, and the rest of the part passes through the air passage 105 to the outside. In this way, while achieving slow air discharge, the air volume and air discharge direction can be increased, as well as the air discharge range can be increased, and the air discharge can also be made softer, the wind feeling is better, and the comfort of the air discharge air flow is improved.

[0099] In some examples, the air conditioner 100 further includes a swing blade assembly (not shown in the figure), the swing blade assembly includes a plurality of swing blades, and the plurality of swing blades are swingably disposed in the air outlet channel 101 and arranged in the first direction. The plurality of swing blades can adjust the airflow direction in the air outlet channel 101 so that the airflow direction of the air outlet 104 meets the use requirements.

[0100] Optionally, the swing blade assembly may include a connecting rod and a plurality of swing blades, the connecting rod extends along a first direction, the plurality of swing blades are rotatably disposed in the air outlet channel 101 and arranged in the extension direction of the connecting rod, and the connecting rod is connected to the plurality of swing blades to enable the plurality of swing blades to be linked.
