Description

Technical Field

[0001] This utility model relates to the field of air conditioning technology, and in particular to an air conditioner. Background Technology

[0002] In related technologies, the air outlet temperature of air conditioners can only be controlled by adjusting the temperature of the heat exchanger. This results in poor comfort when directly blowing cool or hot air, which is quite different from natural wind. Furthermore, the indoor airflow becomes relatively dry after passing through the heat exchanger for cooling. Prolonged cooling leads to low indoor humidity and poor comfort. Utility Model Content

[0003] The present invention aims to solve at least one of the technical problems existing in the prior art. Therefore, one objective of the present invention is to provide an air conditioner that can effectively fine-tune the temperature and humidity of the airflow at the air outlet, making the temperature and humidity of the airflow more comfortable and improving the user experience.

[0021] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0022] The following is for reference. Figures 1-13 This invention describes an air conditioner 100 according to an embodiment of the present invention.

[0023] like Figures 1-4 As shown, the air conditioner 100 according to an embodiment of the present utility model includes a housing 10, the housing 10 includes a front housing 1001 and a rear housing 1004, the rear housing 1004 can be connected to the rear side of the front housing 1001, the front housing 1001 is provided with an air outlet, the number of air outlets can be one or more, and the rear housing 1004 is provided with an air inlet 108, that is, the air inlet 108 is located behind the air outlet.

[0024] The air conditioner 100 also includes a duct component, a fan wheel 60, and a heat exchanger 50. The duct component, fan wheel 60, and heat exchanger 50 are all located inside the outer casing 10. The duct component is connected to the front casing 1001. The duct component defines an air duct 101. The air duct 101 connects the air inlet 108 and the air outlet. The fan wheel 60 is at least partially located inside the air duct 101. The heat exchanger 50 is located between the air inlet 108 and the duct component.

[0025] Among them, such as Figure 4 As shown, the front shell 1001 has a first air passage 1031 inside, the first air passage 1031 is connected to the external space of the front shell 1001, and the first air passage 1031 is connected to the air duct 101 through the first connecting port 1041.

[0026] Furthermore, an air-passing side plate 133 connects the heat exchanger 50 and the duct component. The air-passing side plate 133, the duct component, and the heat exchanger 50 define a first air passage 1031, and a first connecting port 1041 is provided on the air-passing side plate 133. The air-passing side plate 133 connects the heat exchanger 50 and the duct component, allowing for partitioning of the space within the outer casing 10 to form the upstream space of the duct 101 and the first air passage 1031. By providing the first connecting port 1041 on the air-passing side plate 133, communication between the first air passage 1031 and the upstream space of the duct 101 can be achieved. When the impeller 60 rotates, a negative pressure zone is formed between the impeller 60 and the heat exchanger 50, so that the air outside the outer shell 10 can enter the rear shell 1004 from the air inlet 108, exchange heat with the heat exchanger 50, flow into the air duct 101, and finally be discharged from the air outlet.

[0027] During this process, external air can also enter the first air passage 1031 under negative pressure. This part of the air passes through the air passage side plate 133 from the first connecting port 1041, which can reduce the heat exchange with the heat exchanger 50, thereby creating a temperature difference between this part of the air and the air after heat exchange with the heat exchanger 50. This part of the air mixes with the air after heat exchanger 50, and then flows along the air duct 101, and is finally sent out from the air outlet, and so on.

[0028] When the air conditioner 100 is in cooling mode, a negative pressure zone is formed between the impeller 60 and the heat exchanger 50. The warmer air outside the outer casing 10 can enter the rear casing 1004 through the air inlet 108 and exchange heat with the heat exchanger 50, thereby reducing the air temperature. The first air passage 1031 can be used as an air intake passage, allowing the warmer air outside the outer casing 10 to enter the outer casing 10 through the first air passage 1031. The air entering the outer casing 10 through the first air passage 1031 passes through the air passage side plate 133 through the first connecting port 1041 and mixes with the air that has been heated by the heat exchanger 50. Then it flows along the air duct 101. Since the two parts of air have a temperature difference, after mixing, the air with a suitable temperature can finally be sent out from the air outlet.

[0029] Therefore, by introducing external air, on the one hand, the outlet air temperature can be gradually reduced, avoiding discomfort caused by sudden changes in outlet air temperature; on the other hand, the hot air blown out of the outlet will not be too dry, but will have higher humidity, making the airflow softer and more comfortable.

[0030] When the air conditioner 100 is in heating mode, a negative pressure zone is formed between the impeller 60 and the heat exchanger 50. The cooler air outside the outer casing 10 can enter the rear casing 1004 through the air inlet 108 and exchange heat with the heat exchanger 50, thereby increasing the air temperature. The first air passage 1031 can be used as an air intake passage, allowing the cooler air outside the outer casing 10 to enter the outer casing 10 through the first air passage 1031. The air entering the outer casing 10 from the first air passage 1031 passes through the air passage side plate 133 through the first connecting port 1041 and mixes with the air that has been heat exchanged by the heat exchanger 50. Then it flows along the air duct 101. Since the two parts of air have a temperature difference, after mixing, the air with a suitable temperature can finally be sent out from the air outlet.

[0031] Therefore, by introducing external air, on the one hand, the outlet air temperature can be gradually increased to avoid discomfort caused by sudden changes in outlet air temperature, and on the other hand, the humidity of the cool air blown out of the outlet is moderate.

[0032] According to the embodiment of the present invention, the air conditioner 100, by setting an air-passing side plate 133, can define a first air-passing channel 1031 between the air-passing side plate 133, the air duct component and the heat exchanger 50, so that air outside the outer casing 10 can enter the outer casing 10 from the air inlet 108 and the first air-passing channel 1031 respectively. The air entering the outer casing 10 from the air inlet 108 can exchange heat with the heat exchanger 50. The air entering the outer casing 10 from the first air-passing channel 1031 passes through the air-passing side plate 133 through the first connecting port 1041 to reduce the heat exchange with the heat exchanger 50. This part of the air can be mixed with the air that has been heat-exchanged by the heat exchanger 50, and finally sent out at least from the air outlet. To a certain extent, the mixing effect of the airflow is improved, and the temperature and humidity of the airflow at the air outlet are effectively fine-tuned, making the temperature and humidity of the airflow more comfortable and improving the user experience.

[0033] like Figures 4-7 As shown, according to some embodiments of the present invention, the air-passing side plate 133 has a length direction and a width direction. The two sides of the air-passing side plate 133 in the width direction are respectively connected to the end of the heat exchanger 50 and the air duct component. For example, the air-passing side plate 133 can be connected to the end of the heat exchanger 50 and the air duct component by fasteners, thereby realizing the detachable connection between the air-passing side plate 133 and the end of the heat exchanger 50 and the air duct component.

[0034] In the above technical solution, by setting an air-passing side plate 133 between the heat exchanger 50 and the air duct component, the heat exchanger 50 and the air duct component can be connected together using the air-passing side plate 133. This allows for the partitioning design of the space inside the outer shell 10 to form the upstream space of the air duct 101 and the first air-passing channel 1031. By setting a first connecting port 1041 on the air-passing side plate 133, the first air-passing channel 1031 can be connected to the upstream space of the air duct 101, allowing air outside the outer shell 10 to flow from the first air-passing channel 1031 into the upstream space of the air duct 101 under negative pressure, thus achieving the air-drawing effect.

[0035] like Figure 4 As shown, in this embodiment, the first side of the air passage plate 133 in the width direction has a first connecting flange, and the air passage plate 133 is connected to the end of the heat exchanger 50 through the first connecting flange. The second side of the air passage plate 133 in the width direction has a second connecting flange, and the air passage plate 133 is connected to the air duct component through the second connecting flange. By setting the first connecting flange and the second connecting flange, the installation of the air passage plate 133 is more convenient.

[0036] The number of first connecting ports 1041 can be multiple, and the multiple first connecting ports 1041 are arranged in the length direction of the wind-passing side plate 133.

[0037] like Figures 4-7 As shown, according to some embodiments of the present invention, the front shell 1001 has a first air vent 1051, the first air passage 1031 is connected to the external space through the first air vent 1051, and a valve 81 is provided at the first air vent 1051, the valve 81 is used to open and close the first air vent 1051.

[0038] When valve 81 opens the first air inlet 1051, the air conditioner 100 is in operation. Air from outside the casing 10 can enter the casing 10 through the air inlet 108, exchange heat with the heat exchanger 50, flow into the air duct 101, and finally be discharged from the air outlet. During this process, air from outside the casing 10 can also enter the first air passage 1031 through the first air inlet 1051, pass through the first connecting port 1041 and the air passage side plate 133 to reduce heat exchange with the heat exchanger 50, thereby achieving air intake. It mixes with the air passing through the heat exchanger 50, then flows along the air duct 101 and is finally discharged from the air outlet.

[0039] When valve 81 closes the first air inlet 1051, when the air conditioner 100 is working, air outside the outer casing 10 can enter the rear casing 1004 from the air inlet 108, exchange heat with the heat exchanger 50, flow into the air duct 101, and finally be sent out from the air outlet.

[0040] Therefore, by setting valve 81, the opening and closing of the first air inlet 1051 can be realized, thereby enabling the selection of the air intake function of the first air passage 1031 and meeting the user's needs.

[0041] In some specific embodiments, the air conditioner 100 also includes a drive component 82, which is connected to a valve 81 and is used to drive the valve 81 to rotate so that the valve 81 can switch between the state of opening the first air vent 1051 and the state of closing the first air vent 1051, making control more convenient.

[0042] like Figures 4-7 As shown, according to some embodiments of the present invention, the air duct component includes a wind turbine housing 13 and an air outlet frame. The wind turbine 60 is disposed inside the wind turbine housing 13, and the air outlet frame is connected between the wind turbine housing 13 and the front shell 1001. The air outlet frame and the wind turbine housing 13 define different parts of the air outlet duct 101.

[0043] The air passage plate 133 is connected between the heat exchanger 50 and the impeller housing 13. The air outlet frame, the heat exchanger 50, the impeller housing 13 and the air passage plate 133 define the first air passage 1031.

[0044] The heat exchanger 50 includes a heat exchange body and a piping component 53. The piping component 53 is located on the side of the heat exchange body near the front shell 1001 and is situated within the first air passage 1031. Optionally, the two sides of the air passage side plate 133 are connected to the heat exchange body and the air duct component, respectively. In the above technical solution, by setting the air duct components into the above structure, multiple components can be combined to form the air duct 101 and the first air passage 1031, reducing the molding difficulty of each component and thus reducing costs.

[0045] Furthermore, since the structure of the heat exchanger body is relatively flat, connecting the air passage plate 133 to the heat exchanger body makes the connection between the two more convenient. Since there are gaps in the pipe component 53, placing the pipe component 53 in the first air passage 1031 will not affect the air flow and will also ensure that the first air passage 1031 has sufficient flow area, thereby achieving sufficient air volume.

[0046] like Figure 4 As shown, in some embodiments, the front shell 1001 also has a second air passage 1032, which is connected to the external space of the front shell 1001. The second air passage 1032 is connected to the air duct 101 through a second connecting port 1042. The air outlet frame defines the second air passage 1032 and the second connecting port 1042 is located in the air outlet frame.

[0047] Among them, such as Figure 5 and Figure 6 As shown, the front shell 1001 also has a second air vent 1052, the air outlet is located between the first air vent 1051 and the second air vent 1052, and the second air passage 1032 is connected to the external space through the second air vent 1052.

[0048] When the impeller 60 rotates, a negative pressure zone is formed between the impeller 60 and the heat exchanger 50, allowing air from outside the outer casing 10 to enter the rear casing 1004 through the air inlet 108, exchange heat with the heat exchanger 50, flow into the air duct 101, and finally be discharged from the air outlet. During this process, external air can also enter the first air passage 1031 under the action of negative pressure. This part of the air passes through the air passage side plate 133 from the first connecting port 1041, which can reduce the heat exchange with the heat exchanger 50, thereby creating a temperature difference between this part of the air and the air that has exchanged heat with the heat exchanger 50. This part of the air mixes with the air that has passed through the heat exchanger 50, and then flows along the air duct 101, and is finally sent out from the air outlet and the second air passage 1032, and so on.

[0049] It should be noted that during this process, if the area near the second connecting port 1042 within the air duct 101 is under negative pressure, external air can also enter the second air passage 1032 under negative pressure, mix with the air inside the air duct 101, and then be sent out from the air outlet, thus circulating in this way. In other words, at this time, both the first air passage 1031 and the second air passage 1032 serve as air intake channels, thereby forming a pattern of air intake on both sides and air outlet in the middle.

[0050] When the air conditioner 100 is in cooling mode, a negative pressure zone is formed between the impeller 60 and the heat exchanger 50. The air with a higher temperature outside the outer casing 10 can enter the rear casing 1004 through the air inlet 108 and exchange heat with the heat exchanger 50, thereby reducing the air temperature. The first air passage 1031 can be used as an air intake passage, so that the air with a higher temperature outside the outer casing 10 can enter the outer casing 10 through the first air passage 1031. The air entering the outer casing 10 through the first air passage 1031 passes through the air passage side plate 133 through the first connecting port 1041 and mixes with the air that has been heat exchanged by the heat exchanger 50. Then it flows along the air duct 101. Since the two parts of air have a temperature difference, after mixing, they can finally be sent out from the air outlet and the second air passage 1032.

[0051] Or, such as Figure 7As shown, the warmer air outside the outer shell 10 can enter the rear shell 1004 through the air inlet 108 and exchange heat with the heat exchanger 50. The first air passage 1031 can be used as an air intake passage, allowing the warmer air outside the outer shell 10 to enter the outer shell 10 through the first air passage 1031. The air entering the outer shell 10 through the first air passage 1031 passes through the air passage side plate 133 through the first connecting port 1041 and mixes with the air that has been heated by the heat exchanger 50. Then it flows along the air duct 101. The second air passage 1032 can also be used as an air intake passage, allowing the warmer air outside the outer shell 10 to also enter the air duct 101 through the second air passage 1032. Finally, it is sent out only from the air outlet.

[0052] When the air conditioner 100 is in heating mode, a negative pressure zone is formed between the fan wheel 60 and the heat exchanger 50. The cooler air outside the outer casing 10 can enter the rear casing 1004 through the air inlet 108 and exchange heat with the heat exchanger 50, thereby increasing the air temperature. The first air passage 1031 can be used as an air intake passage, allowing the cooler air outside the outer casing 10 to enter the outer casing 10 through the first air passage 1031. The air entering the outer casing 10 from the first air passage 1031 passes through the air passage side plate 133 through the first connecting port 1041 and mixes with the air that has been heated by the heat exchanger 50. Then it flows along the air duct 101. Since the two parts of air have a temperature difference, after mixing, they can finally be sent out from the air outlet and the second air passage 1032.

[0053] Or, such as Figure 7 As shown, cooler air outside the outer casing 10 can enter the rear casing 1004 through the air inlet 108 and exchange heat with the heat exchanger 50. The first air passage 1031 can serve as an air intake passage, allowing cooler air outside the outer casing 10 to enter the outer casing 10 through the first air passage 1031. The air entering the outer casing 10 through the first air passage 1031 passes through the air passage side plate 133 through the first connecting port 1041 and mixes with the air that has been heat-exchanged by the heat exchanger 50. Then it flows along the air duct 101. The second air passage 1032 can also serve as an air intake passage, allowing cooler air outside the outer casing 10 to also enter the air duct 101 through the second air passage 1032. Finally, it is sent out only from the air outlet.

[0054] like Figure 7 As shown, in some embodiments, the second connection port 1042 has a first edge S1 and a second edge S2 disposed opposite to each other. The second edge S2 is disposed closer to the air outlet than the first edge S1. The second edge S2 is located on the side of the air duct wall 1015 where the first edge S1 is located or the extension surface S3 of the air duct wall 1015 away from the air duct 101.

[0055] Wherein, the first edge S1 and the second edge S2 can be straight lines or curves. The extension surface S3 of the duct wall 1015 refers to the extension and stretching of the duct wall 1015, where the first edge S1 is located, following the original trend. The duct wall 1015, where the first edge S1 is located, can be a plane or a curved surface. In the embodiment where the duct wall 1015 is a plane, the extension surface S3 of the duct wall 1015 is located on the plane where the duct wall 1015 is located; in the embodiment where the duct wall 1015 is a curved surface, the extension surface S3 of the duct wall 1015 is extended and stretched according to the original trend of the curved surface.

[0056] Therefore, by restricting the first edge S1 and the second edge S2 of the second connecting port 1042 to meet the above conditions, a pressure difference is formed in the area where the second connecting port 1042 is located. When high-speed flowing gas flows out of the air outlet, a local negative pressure zone can be formed in the air duct 101, so that the air outside the outer shell 10 can be introduced into the air duct 101 through the second air passage 1032 for mixing, and finally sent out from the air outlet. This improves the mixing effect of the airflow to a certain extent, effectively fine-tunes the airflow temperature and humidity at the air outlet, making the temperature and humidity of the airflow more comfortable and improving the user experience.

[0057] like Figure 7 As shown, the vertical distance L between the second edge S2 and the duct wall 1015 or the extended surface S3 is greater than 3mm. If the vertical distance L between the second edge S2 and the duct wall 1015 or the extended surface S3 is too small, sufficient external air cannot be introduced, resulting in an insignificant air intake effect.

[0058] It should be noted that when the duct wall 1015 is a curved surface, the vertical distance L between the second edge S2 and the duct wall 1015 is the distance between the second edge S2 and the tangent surface of the duct wall 1015 at the first edge S1.

[0059] In the above technical solution, by limiting the vertical distance L between the second edge S2 and the duct wall 1015 or the extended surface S3 to meet the above conditions, the second air passage 1032 can form an air intake passage when the air outlet is in the open state, so as to introduce sufficient external air into the air conditioner 100 to regulate the temperature and humidity of the air outlet airflow, and also to regulate the air volume of the air outlet.

[0060] In some examples, the distance between the projection of the second edge S2 onto the duct wall 1015 or the extended surface S3 and the first edge S1 is A. The distance A cannot be too large or too small, otherwise air leakage problems are likely to occur. In some embodiments, the distance A between the projection of the second edge S2 onto the duct wall 1015 or the extended surface S3 and the first edge S1 satisfies the condition: 1mm ≤ A ≤ 30mm. For example, the distance A between the projection of the second edge S2 onto the duct wall 1015 or the extended surface S3 and the first edge S1 can be 1mm, 5mm, 10mm, 15mm, 20mm, 25mm, 30mm, etc. This setting can reduce the occurrence of air leakage problems.

[0061] In some specific embodiments, 5mm≤A≤10mm can further reduce the occurrence of air leakage problems.

[0062] like Figure 7 As shown, according to some embodiments of the present invention, the second edge S2 is located on the side of the duct 101 away from the first edge S1. That is, the distance between the second edge S2 of the second connection 1042 and the duct wall of the duct 101 is greater than 0.

[0063] Therefore, by restricting the first edge S1 and the second edge S2 of the second connecting port 1042 to meet the above conditions, a pressure difference is formed in the area where the second connecting port 1042 is located. When high-speed flowing gas flows out of the air outlet, a local negative pressure zone can be formed in the air duct 101, so that the air outside the outer shell 10 can be introduced into the air duct 101 through the second air passage 1032 for mixing, and finally sent out from the air outlet. This improves the mixing effect of the airflow to a certain extent, effectively fine-tunes the airflow temperature and humidity at the air outlet, making the temperature and humidity of the airflow more comfortable and improving the user experience.

[0064] In some embodiments, the distance between the second edge S2 and the cut surface is greater than 3 mm. If the distance between the second edge S2 and the cut surface is too small, insufficient external air cannot be introduced, resulting in an insignificant air intake effect.

[0065] In the above technical solution, by limiting the distance between the second edge S2 and the tangent to meet the above conditions, the second air passage 1032 can form an air intake passage when the air outlet is in the open state, so as to introduce sufficient external air into the air conditioner 100 to regulate the temperature and humidity of the air outlet airflow, and also to regulate the air volume of the air outlet.

[0066] Specifically, the distance between the second edge S2 of the second connecting port 1042 and the corresponding tangent can be 4mm, 6mm, 8mm, 10mm, 12mm, 14mm, etc.

[0067] If the distance between the second edge S2 and the cut surface is too large, meeting this distance will increase the size of the air conditioner 100, increase the materials used and the cost, and will also be detrimental to the miniaturization design of the air conditioner 100. Therefore, in some embodiments, the distance between the second edge S2 and the cut surface is less than or equal to 30mm.

[0068] like Figure 7 As shown, the distance between the projection of the second edge S2 on the cut surface and the first edge S1 cannot be too large or too small, otherwise air leakage is likely to occur. In some embodiments, the distance between the projection of the second edge S2 on the cut surface and the first edge S1 is greater than 1 mm and less than 30 mm, or equal to 1 mm or equal to 30 mm. For example, the distance between the projection of the second edge S2 on the cut surface and the first edge S1 can be 5 mm, 10 mm, 15 mm, 20 mm, 25 mm, etc. This setting can reduce the occurrence of air leakage problems.

[0069] In some specific embodiments, the distance between the projection of the second edge S2 on the cut surface and the first edge S1 is greater than 5mm and less than 10mm, or equal to 5mm, or equal to 10mm, which can further reduce the occurrence of air leakage problems.

[0070] like Figures 4-7 As shown, in some specific embodiments, the air outlet frame includes a first frame 11 and a second frame 12. The two sides of the first frame 11 are respectively connected to the impeller housing 13 and one side of the second frame 12. The other side of the second frame 12 is connected to the front shell 1001. The first frame 11, the heat exchanger 50, the impeller housing 13 and the air passage side plate 133 define at least a portion of the first air passage 1031. The first frame 11 defines a second air passage 1032 and a second connecting port 1042 is provided in the first frame 11.

[0071] Therefore, by setting the air outlet frame to include a first frame 11 and a second frame 12 that are separately configured, and by combining multiple relatively simple structures to form a relatively complex structure, the structure of the air outlet frame can be simplified, the molding difficulty of the air outlet frame can be reduced, and it is beneficial to reduce costs and improve production efficiency.

[0072] like Figures 10-13 As shown, the second frame 12 or the front shell 1001 has a positioning post 1211 and a first connecting hole 1212, and the first frame 11 has a positioning hole 113 and a second connecting hole 114. The positioning post 1211 is inserted into the positioning hole 113. The second frame 12 or the front shell 1001 is connected to the first frame 11 by fasteners. The fasteners pass through the first connecting hole 1212 and the second connecting hole 114, thereby ensuring the reliability of the connection between the second frame 12 or the front shell 1001 and the first frame 11.

[0073] Specifically, the right side of the first frame 11 is provided with multiple mounting plates 115, which are spaced apart along the length of the first frame 11 (as shown in Figure 10). Each mounting plate 115 is provided with a positioning hole 113 and a second connecting hole 114. Correspondingly, the right side of the front shell 1001 is provided with multiple sets of positioning posts 1211 and first connecting holes 1212. The positioning holes 113 on the multiple mounting plates 115 are inserted into the multiple positioning posts 1211 in a one-to-one correspondence. The second connecting holes 114 on the multiple mounting plates 115 are positioned in a one-to-one correspondence with the multiple first connecting holes 1212. Thus, the front shell 1001 and the first frame 11 can be connected together by multiple fasteners, ensuring the reliability of the connection between the front shell 1001 and the first frame 11.

[0074] Furthermore, the left side of the first frame 11 is provided with a plurality of positioning holes 113 and a plurality of second connecting holes 114, the number of positioning holes 113 and the number of second connecting holes 114 are equal, and the plurality of positioning holes 113 and the plurality of second connecting holes 114 are respectively provided along the length direction of the first frame 11 (e.g., ...). Figure 12 As shown in the vertical direction, multiple positioning holes 113 and multiple second connecting holes 114 are arranged at intervals, one-to-one correspondingly close to each other. Correspondingly, multiple positioning posts 1211 and multiple first connecting holes 1212 are respectively provided on the left side of the second frame 12. The multiple positioning holes 113 and multiple positioning posts 1211 are inserted and engaged one-to-one, and the multiple second connecting holes 114 and multiple first connecting holes 1212 are positioned one-to-one. Thus, the second frame 12 and the first frame 11 can be connected together by multiple fasteners, ensuring the reliability of the connection between the second frame 12 and the first frame 11.

[0075] like Figures 4-7 As shown, in some examples, the impeller housing 13 includes a volute 132 and a volute tongue 131 disposed opposite to each other, and the first frame 11 includes a first side plate 111 and a second side plate 112 disposed opposite to each other. The two sides of the first side plate 111 are respectively connected to the volute tongue 131 and one side of the second frame 12, and the two sides of the second side plate 112 are respectively connected to the volute 132 and one side of the second frame 12.

[0076] The second connecting port 1042 is located on the second side plate 112, and the second connecting port 1042 is opposite to the volute tongue 131. The wind-passing side plate 133 is connected to the side of the volute tongue 131 away from the second side plate 112.

[0077] With this configuration, the first air passage 1031 can be placed on the side of the volute tongue 131 away from the second side plate 112, thereby effectively utilizing the space on the side of the volute tongue 131 away from the second side plate 112, making the structure more compact and improving the space utilization rate inside the outer shell 10.

[0078] like Figures 12-13 As shown, in some specific examples, the second frame 12 is provided with two baffles 1213 on the side facing the heat exchanger 50, and the two baffles 1213 are in the length direction of the second frame 12 (e.g., Figure 12 The two baffles 1213 are arranged at intervals in the vertical direction shown, and the two baffles 1213 abut against the heat exchanger 50 and the first side plate 111 to seal the first air passage 1031, which can ensure the airtightness of the first air passage 1031, so that the outside air can enter the upstream of the air duct 101 through the first air passage 1031 under the action of negative pressure.

[0079] like Figures 4-7 As shown, in some embodiments, the air duct 101 includes a main channel 1011, a first branch channel 1012 and a second branch channel 1013, and at least two air outlets, which are a first air outlet 1021 and a second air outlet 1022, respectively. The first branch channel 1012 connects the first air outlet 1021 and the main channel 1011, and the second branch channel 1013 connects the second air outlet 1022 and the main channel 1011. The first frame 11 defines the main channel 1011, and the second frame 12 includes a frame body 121 and a partition 122. The partition 122 is disposed inside the frame body 121 to divide the inner cavity of the frame body 121 into the first branch channel 1012 and the second branch channel 1013.

[0080] Specifically, when the air conditioner 100 is working, as the fan wheel 60 rotates, a negative pressure zone can be formed upstream of the air duct 101. Under the action of negative pressure, the air outside the outer casing 10 can enter the outer casing 10 from the air inlet 108 and the first air passage 1031 respectively. The air entering the outer casing 10 from the air inlet 108 flows through the heat exchanger 50 to exchange heat with the heat exchanger 50. The air entering the outer casing 10 from the first air passage 1031 mixes with the air after heat exchange by the heat exchanger 50 and flows into the main passage 1011. Part of the airflow is discharged to the outside of the outer casing 10 along the second air passage 1032, part of the airflow is discharged from the first air outlet 1021 along the first branch passage 1012, and another part of the airflow is discharged from the second air outlet 1022 along the second branch passage 1013.

[0081] Of course, it is also possible that when the air conditioner 100 is working, as the fan wheel 60 rotates, a negative pressure zone can be formed upstream of the air duct 101. Under the action of negative pressure, the air outside the outer casing 10 can enter the rear casing 1004 from the air inlet 108 and exchange heat with the heat exchanger 50. The first air passage 1031 can be used as an air intake passage, so that the air outside the outer casing 10 can also be introduced into the upstream of the air duct 101 through the first air passage 1031 and mixed with the air that has been heated by the heat exchanger 50, and then flow along the air duct 101. The second air passage 1032 can also be used as an air intake passage, so that the air outside the outer casing 10 can also enter the air duct 101 through the second air passage 1032 and finally be sent out only from the air outlet.

[0082] In the above technical solution, by setting a first air outlet 1021, a second air outlet 1022, a first branch channel 1012 and a second branch channel 1013, multiple air outlets can be used to output air, which improves the user experience.

[0083] like Figure 4 As shown, in some examples, the front housing 1001 includes a front panel 1002, which is located on the side of the partition 122 facing away from the main channel 1011, and the first air outlet 1021 and the second air outlet 1022 are located on both sides of the front panel 1002.

[0084] In the above technical solution, by setting the front panel 1002 on the side of the partition 122 facing away from the main channel 1011, the front panel 1002 can cover the partition 122, ensuring that the appearance of the air conditioner 100 is flatter and more beautiful, which is conducive to improving the visual experience.

[0085] like Figure 4 and Figure 5 As shown, in some specific examples, the partition 122 includes a first guide plate 1221 and a second guide plate 1222. The first guide plate 1221 and the second guide plate 1222 are arranged at an angle and extend away from each other along the air outlet direction. The first guide plate 1221 forms part of the wall of the first branch channel 1012, and the second guide plate 1222 forms part of the wall of the second branch channel 1013. The two ends of the front panel 1002 are respectively connected to the first guide plate 1221 and the second guide plate 1222.

[0086] In the above technical solution, by setting the partition 122 as the first guide plate 1221 and the second guide plate 1222, the airflow in the main channel 1011 can be split, and the air in the main channel 1011 can be guided to the first branch channel 1012 and the second branch channel 1013 respectively, so as to ensure that the air volume of the first air outlet 1021 and the second air outlet 1022 can meet the needs.

[0087] like Figures 5-7 As shown, in some specific examples, the partition 122 is provided with a diverter 124 on the side facing the main channel 1011. The diverter 124 is used to guide the airflow in the main channel 1011 to flow into the first branch channel 1012 and the second branch channel 1013 respectively.

[0088] The diverter 124 has a first diverting surface 1241 and a second diverting surface 1242, which are arranged opposite to each other. One end of the first diverting surface 1241 and one end of the second diverting surface 1242 are connected. The other end of the first diverting surface 1241 and the other end of the second diverting surface 1242 extend into the first branch channel 1012 and the second branch channel 1013 respectively along the air outlet direction in a direction away from each other.

[0089] In the above technical solution, by setting a diverter 124 on the side of the partition 122 away from the front panel 1002, the diverter 124 can correct the diversion effect of the partition 122, so that the airflow in the main channel 1011 can be better diverted. The airflow in the main channel 1011 can be introduced into the first branch channel 1012 under the guidance of the first diversion surface 1241 and into the second branch channel 1013 under the guidance of the second diversion surface 1242, so as to ensure that the air volume of the first air outlet 1021 and the second air outlet 1022 can meet the requirements.

[0090] like Figures 4-7 As shown, in order to ensure the diversion effect of the diversion component 124 and reduce air volume loss, the included angle between the tangents of the first diversion surface 1241 and the second diversion surface 1242 at the connection is an acute angle. For example, the included angle γ between the tangents of the first diversion surface 1241 and the second diversion surface 1242 at the connection can be less than or equal to 30°.

[0091] like Figures 4-7 as well as Figures 12-13 As shown, in some embodiments, a sway assembly 40 is provided in the first branch channel 1012. The sway assembly 40 includes a connecting rod 41 and a plurality of sway blades 42. The plurality of sway blades 42 are rotatably disposed on the first guide plate 1221. The connecting rod 41 is connected to the plurality of sway blades 42 so that the plurality of sway blades 42 are linked together. The sway assembly 40 can adjust the airflow direction in the first branch channel 1012 so that the airflow direction of the first air outlet 1021 meets the usage requirements.

[0092] In some embodiments, a sway assembly 40 is provided in the second branch channel 1013. The sway assembly 40 includes a connecting rod 41 and a plurality of sway blades 42. The plurality of sway blades 42 are rotatably disposed on the second guide plate 1222. The connecting rod 41 is connected to the plurality of sway blades 42 so that the plurality of sway blades 42 are linked together. The sway assembly 40 can adjust the airflow direction in the second branch channel 1013 so that the airflow direction of the second air outlet 1022 meets the usage requirements.

[0093] like Figure 1 As shown, in some embodiments, in the cross-section of the air conditioner 100, the air conditioner 100 has a centerline P, and the first air outlet 1021 and the second air outlet 1022 are located on both sides of the centerline P (e.g., Figure 1 As shown on the left and right sides), the extension directions of the first branch channel 1012 and the second branch channel 1013 are not at equal angles with the center line P, and the extension directions of the first air passage 1031 and the second air passage 1032 are not at equal angles with the center line P.

[0094] Specifically, the angle between the extension direction of the first branch channel 1012 and the center line P is β1, and the angle between the extension direction of the second branch channel 1013 and the center line P is β2, where β1 is not equal to β2.

[0095] In this embodiment, the center of the impeller 60 is located on one side of the center line P, that is, the impeller 60 is offset relative to the center line P. Therefore, by limiting the above conditions, the air volume loss can be reduced and the temperature regulation efficiency of the air conditioner 100 can be improved.

[0096] Furthermore, the first air outlet 1021 and the second air outlet 1022 are symmetrically arranged about the center line P. The first air passage 1031 and the external space of the outer shell 10 are connected through the first air passage 1051, and the second air passage 1032 and the external space of the outer shell 10 are connected through the second air passage 1052. The first air passage 1051 and the second air passage 1052 are symmetrically arranged about the center line P.

[0097] Since the first air outlet 1021 and the second air outlet 1022, the first air vent 1051 and the second air vent 1052 are exposed on the outside of the outer casing 10, they serve as the appearance structure of the air conditioner 100. By defining the first air outlet 1021 and the second air outlet 1022, the first air vent 1051 and the second air vent 1052 as symmetrically arranged about the center line P, the appearance of the air conditioner 100 is symmetrical, which is beneficial to improving the visual experience.

[0098] like Figures 2-3 , Figures 4-7As shown, a first air vent 1051 and a second air vent 1052 are disposed on the front housing 1001. The first air vent 1051 and the second air vent 1052 can be defined by a grille structure, so that both the first air vent 1051 and the second air vent 1052 are constructed to include multiple elongated holes. For example, the multiple elongated holes are arranged in a manner similar to... Figures 2-3 The front shell 1001 is arranged along its height. Of course, the first air vent 1051 and the second air vent 1052 may also each include multiple circular hole structures.

[0099] Therefore, by setting the first air vent 1051 and the second air vent 1052 into the above structure, on the one hand, the structural strength of the front shell 1001 can be guaranteed, and on the other hand, the grille structure can be used to construct each air vent to include multiple through holes (e.g., elongated holes), which can prevent foreign objects from being rolled into the corresponding air vents and also prevent fingers from being inserted into the air conditioner 100, thus ensuring the user's safety.

[0100] like Figures 4-7 As shown, according to some embodiments of the present invention, the air conditioner 100 further includes an air guide assembly 20, which includes a movable air guide for covering or opening the air outlet, and the air guide is provided with a plurality of air dissipation holes 201.

[0101] The air conditioner 100 has a first air supply state and a second air supply state.

[0102] In the first air supply state, the air guide opens the air outlet. When the impeller 60 rotates, a negative pressure zone is formed between the impeller 60 and the heat exchanger 50, allowing air from outside the outer casing 10 to enter the rear casing 1004 through the air inlet 108, exchange heat with the heat exchanger 50, flow into the air duct 101, and finally exit from the air outlet. During this process, since the first air passage 1051 is located upstream of the air duct 101 in the airflow direction, external air can enter the first air passage 1031 under the action of negative pressure, thus entering the upper reaches of the air duct 101 and mixing with the air passing through the heat exchanger 50. Then, it flows along the air duct 101 and is finally delivered from the air outlet and the second air passage 1032. Part of the airflow in the air duct 101 can be discharged to the outside of the outer casing 10 through the second air passage 1032, and another part of the airflow can be directly discharged to the outside of the outer casing 10 through the air outlet, which can achieve large-volume air supply.

[0103] Or, such as Figure 7As shown, air outside the outer casing 10 can enter the rear casing 1004 through the air inlet 108 and exchange heat with the heat exchanger 50. The first air passage 1031 can be used as an air intake passage, so that air outside the outer casing 10 can also be introduced into the upstream of the air duct 101 through the first air passage 1031 and mixed with the air that has been heated by the heat exchanger 50, and then flow along the air duct 101. The second air passage 1032 can also be used as an air intake passage, so that air outside the outer casing 10 can also enter the air duct 101 through the second air passage 1032, and finally be sent out only from the air outlet.

[0104] In the second air supply state, the air guide covers the air outlet, and part of the airflow in the air duct 101 can be discharged to the outside of the outer casing 10 through the second air passage 1032, while another part of the airflow can be discharged through the multiple air diffusers 201 of the air guide, effectively improving the airflow and cooling capacity without a wind feeling.

[0105] Of course, the air supply state of the air conditioner 100 is not limited to the two mentioned above. During the operation of the air conditioner 100, the air guide can also be controlled to swing periodically. During the swing of the air guide, the positive and negative pressure in the air duct 101 switches, so that the second air passage 1032 switches between the air intake function and the air exhaust function, thereby making the air conditioner 100 form an intake and exhaust effect similar to breathing.

[0106] In the above technical solution, by setting the air guide component 20, the switching between the first air supply state and the second air supply state can be realized, thereby meeting a variety of usage needs.

[0107] like Figures 1-7 As shown, in this embodiment, there are two air outlets, namely the first air outlet 1021 and the second air outlet 1022, and two air guides, namely the first air guide 21 and the second air guide 22. The first air guide 21 and the second air guide 22 are used to cover or open the first air outlet 1021 and the second air outlet 1022 respectively. The first air guide 21 and the second air guide 22 are each provided with a plurality of air dissipation holes 201.

[0108] The air conditioner 100 has a first air supply state and a second air supply state.

[0109] like Figure 4 As shown, in the first air supply state, each of the first air guide 21 and the second air guide 22 opens its corresponding air outlet, and the first air passage 1031 is an air intake passage.

[0110] Specifically, in this state, the first air guide 21 opens the first air outlet 1021, and the second air guide 22 opens the second air outlet 1022. A portion of the airflow in the main channel 1011 can be discharged to the outside of the outer casing 10 through the second air passage 1032, a portion of the airflow can be discharged to the outside of the outer casing 10 along the first branch channel 1012 from the first air outlet 1021, and another portion of the airflow can be discharged to the outside of the outer casing 10 along the second branch channel 1013 from the second air outlet 1022, thus achieving large-volume air delivery.

[0111] Or, such as Figure 7 As shown, the second air passage 1032 is also an air intake passage, which allows air outside the outer casing 10 to enter the air duct 101 through the second air passage 1032. Part of the airflow can be discharged from the first air outlet 1021 to the outside of the outer casing 10 along the first branch passage 1012, and another part of the airflow can be discharged from the second air outlet 1022 to the outside of the outer casing 10 along the second branch passage 1013, which can achieve large air volume delivery.

[0112] like Figure 5 As shown, in the second air supply state, each of the first air guide 21 and the second air guide 22 covers the corresponding air outlet so that the second air passage 1032 forms an exhaust passage.

[0113] Specifically, in this state, the first air guide 21 covers the first air outlet 1021, and the second air guide 22 covers the second air outlet 1022. A portion of the airflow in the main channel 1011 can be discharged to the outside of the outer casing 10 through the second air passage 1032, a portion of the airflow can be discharged to the outside of the outer casing 10 along the first branch channel 1012 from the multiple air diffusers 201 of the first air guide 21, and another portion of the airflow can be discharged to the outside of the outer casing 10 along the second branch channel 1013 from the multiple air diffusers 201 of the second air guide 22, effectively improving the airflow and cooling capacity without a draft.

[0114] In some embodiments, the air conditioner 100 further includes a door opening and closing assembly 30, which includes a door for opening and closing air outlets. In a first air supply state and a second air supply state, the door opens the corresponding air outlet.

[0115] like Figures 1-2 , Figures 4-10 As shown, in this embodiment, there are two air outlets, namely the first air outlet 1021 and the second air outlet 1022, and two switch doors, namely the first switch door 31 and the second switch door 32. The first switch door 31 and the second switch door 32 are used to open and close the first air outlet 1021 and the second air outlet 1022, respectively. In the first air supply state and the second air supply state, the first switch door 31 and the second switch door 32 open the corresponding air outlets.

[0116] Specifically, when the air conditioner 100 is off, the first door 31 can be controlled to close the first air outlet 1021, and the second door 32 can be controlled to close the second air outlet 1022, preventing dust from entering the outer casing 10 through the first air outlet 1021 and the second air outlet 1022. When the air conditioner 100 is working, the first door 31 can be controlled to open the first air outlet 1021, and the second door 32 can be controlled to open the second air outlet 1022.

[0117] Therefore, by setting up movable first and second doors 31 and 32, and utilizing the relatively simple structure and low cost of the first and second doors 31 and 32, the corresponding air outlets can be opened and closed. The position states of the first air guide 21 and the second air guide 22 can be combined to create a variety of air supply states, thereby increasing the functionality of the air conditioner 100 and meeting different usage needs.

[0118] Understandably, the air pressure at the first branch channel 1012 and the second branch channel 1013 can be adjusted by controlling the opening of the first and second opening doors 31 and 32, as well as the first and second air guides 21 and 22. This changes the airflow volume of the second air passage 1032, the airflow volume of the first and second air outlets 1021 and 1022, thereby achieving multi-directional airflow and multi-area cooling or heat dissipation, improving the airflow effect and user experience. Of course, the airflow direction can also be changed by controlling the sway vane assembly 40; for example, multiple sway vanes 42 can swing up and down.

[0119] According to some embodiments of this utility model, the air conditioner 100 is a cabinet air conditioner 100. The air conditioner 100 can be the indoor unit of a split-type air conditioner or an integrated air conditioner 100.

[0131] The fan includes a fan wheel 60, which can be a cross-flow fan wheel 60. The fan wheel 60 is rotatably disposed inside the fan wheel housing 13. The rotation center of the fan wheel 60 is located to the right of the center line P of the air conditioner 100. The volute tongue 131 is located on the left wall of the fan wheel housing 13 and extends to the right.

[0132] A heat exchanger 50 is disposed between the air inlet 108 and the impeller 60 of the rear shell 1004. The heat exchanger 50 includes a heat exchange body and piping components. The heat exchange body includes a first heat exchange section 51 and a second heat exchange section 52.

[0134] The air guiding assembly 20 includes a first air guiding component 21, a second air guiding component 22, a first upper motor 23, and a second upper motor 24. The first air guiding component 21 is rotatably disposed at the first air outlet 1021 to open or cover the first air outlet 1021.

The second upper motor 24 is disposed above the second air guiding component 22 and connected to the second air guiding component 22 to drive the second air guiding component 22 to rotate. Both the first air guiding component 21 and the second air guiding component 22 are provided with multiple air dissipation holes 201.

[0135] The door opening and closing assembly 30 includes a first door opening 31, a second door opening 32, a first lower motor 33, and a second lower motor 34. The first door opening 31 is rotatably disposed at the first air outlet 1021 between a first position and a second position. The first lower motor 33 is disposed below the first door opening 31 and connected to the first door opening 31 to drive the first door opening 31 to rotate. The second door opening 32 is rotatably disposed at the second air outlet 1022 between a first position and a second position. The second lower motor 34 is disposed below the second door opening 32 and connected to the second door opening 32 to drive the second door opening 32 to rotate.

[0136] The first switch door 31 is located on the side of the first air guide 21 opposite to its rotation axis, and the second switch door 32 is located on the side of the second air guide 22 opposite to its rotation axis. The rotation axis of the first switch door 31 coincides with the rotation axis of the first air guide 21, and the rotation axis of the second switch door 32 coincides with the rotation axis of the second air guide 22.

[0137] When the air conditioner 100 is in the off state, the first switch door 31 is located in front of the first air guide 21 to close the first air outlet 1021 and serves as the appearance structure of the air conditioner 100, and the second switch door 32 is located in front of the second air guide 22 to close the second air outlet 1022 and serves as the appearance structure of the air conditioner 100.

[0138] The air conditioner 100 has at least an off state, a first air supply state, and a second air supply state.

[0139] When the machine is off, the first switch door 31 and the second switch door 32 are in the first position, the first switch door 31 closes the first air outlet 1021, and the second switch door 32 closes the second air outlet 1022.

[0140] like Figure 4 As shown, in the first air supply state, both the first switch door 31 and the second switch door 32 are in the open position. The first air guide 21 opens the first air outlet 1021, and the second air guide 22 opens the second air outlet 1022. As the impeller 60 rotates, a negative pressure zone can be formed upstream of the air duct 101. Under the action of negative pressure, the air outside the outer casing 10 can enter the outer casing 10 from the air inlet 108 and the first air passage 1031 respectively. The air entering the outer casing 10 from the air inlet 108 flows through the heat exchanger 50 to interact with the heat exchanger 50. Heat exchange is performed. The air entering the outer casing 10 from the first air passage 1031 mixes with the air that has been heated by the heat exchanger 50 and flows into the main passage 1011. Part of the airflow in the main passage 1011 can be discharged to the outside of the outer casing 10 through the second air passage 1032, part of the airflow can be discharged to the outside of the outer casing 10 along the first branch passage 1012 from the first air outlet 1021, and another part of the airflow can be discharged to the outside of the outer casing 10 along the second branch passage 1013 from the second air outlet 1022, which can achieve large air volume delivery.

[0141] Alternatively, the second air passage 1032 can also serve as an air intake passage, allowing air from outside the outer casing 10 to enter the air duct 101 through the second air passage 1032 and ultimately be sent out only from the air outlet.

[0142] like Figure 5 As shown, in the second air supply state, both the first switch door 31 and the second switch door 32 are in the open position. The first air guide 21 covers the first air outlet 1021, and the second air guide 22 covers the second air outlet 1022. As the impeller 60 rotates, a negative pressure zone can be formed upstream of the air duct 101. Under the action of negative pressure, the air outside the outer casing 10 can enter the outer casing 10 from the air inlet 108 and the first air passage 1031, respectively. The air entering the outer casing 10 from the air inlet 108 flows through the heat exchanger 50 to exchange heat with the heat exchanger 50. The air entering the housing 10 through the air duct 1031 mixes with the air after heat exchange by the heat exchanger 50 and flows into the main duct 1011. Part of the airflow in the main duct 1011 can be discharged to the outside of the housing 10 through the second air passage 1032, part of the airflow can be discharged to the outside of the housing 10 along the first branch duct 1012 from the multiple air diffusers 201 of the first air guide 21, and another part of the airflow can be discharged to the outside of the housing 10 along the second branch duct 1013 from the multiple air diffusers 201 of the second air guide 22, effectively improving the airflow and cooling capacity without a draft.

[0143] In the above technical solution, by setting the first air passage 1031, hot or cold air from outside the outer casing 10 can be effectively introduced into the upstream of the air duct 101 and mixed with the air after heat exchange by the heat exchanger 50 before being sent out. To a certain extent, the temperature and humidity of the air at the outlet are effectively fine-tuned, making the temperature and humidity of the air at the outlet more comfortable.
