[0066] Embodiments of the present application 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 intended to be used to explain the present application, and should not be construed as limiting the present application.

[0067] The disclosure below provides many different embodiments or examples to realize the different structures of the present application. In order to simplify the disclosure of the present application, the parts and settings of specific examples are described below. Of course, they are only examples, and the purpose is not to limit the present application. In addition, the present application can repeat reference numbers and / or letters in different examples. This repetition is for the purpose of simplification and clarity, and does not indicate the relationship between the various embodiments and / or settings discussed in itself. In addition, the various specific processes and examples of materials provided by the present application, but those of ordinary skill in the art can appreciate the applicability of other processes and / or the use of other materials.

[0068] Hereinafter, an air conditioner 100 according to an embodiment of the present application will be described with reference to the accompanying drawings.

[0069] like Figure 1-Figure 3 As shown, the air conditioner 100 may include: a housing assembly 1, a first fan 31 and a second fan 32, the housing assembly 1 having a first air outlet 11 and a second air outlet 12 spaced apart from each other, Figure 4-Figure 7 The shell assembly 1 has a first air duct 21 that can deliver airflow to any one of the first air supply port 11 and the second air supply port 12, and a second air duct 22 that can deliver airflow to the second air supply port 12. The first fan 31 is connected to the first air duct 21 to induce airflow to flow through the first air duct 21, and the second fan 32 is connected to the second air duct 22 to induce airflow to flow through the second air duct 22.

[0070] In this way, when the first fan 31 is working and the first air supply port 11 is open, the first fan 31 can form an airflow in the first air duct 21 and can be transported toward any one of the first air supply port 11 and the second air supply port 12. When the second fan 32 is working and the second air supply port 12 is open, the second fan 32 can form an airflow in the second air duct 22 and can be transported toward the second air supply port 12.

[0071] It is worth noting that the relative position of the first fan 31 and the first air duct 21 is not limited, for example, the first fan 31 can be located upstream, inside, or downstream of the first air duct 21, and the relative position of the second fan 32 and the second air duct 22 is not limited, for example, the second fan 32 can be located upstream, inside, or downstream of the second air duct 22. To simplify the description, the following only takes the first fan 31 located upstream of the first air duct 21 (that is, the outlet of the first fan 31 is connected to the inlet of the first air duct 21) and the second fan 32 located upstream of the second air duct 22 (that is, the outlet of the second fan 32 is connected to the inlet of the second air duct 22) as an example for description.

[0072] In the embodiment of the present application, the air conditioner 100 further includes a switching component, which is used to adjust the on-off of the air flow path and has at least a first switching state and a second switching state. In the first switching state, the air flow introduced into the first air duct 21 by the first fan 31 is sent out through the first air supply port 11, and in the second switching state, the air flow introduced into the first air duct 21 by the first fan 31 is sent out through the second air supply port 12. Thus, the air conditioner 100 can switch different working modes to achieve a variety of air supply effects.

[0073] It is worth noting that the specific structure of the switching component and which airflow path is used to control the on and off of can be flexibly designed according to the connection method between the first channel 21 and the first air supply port 11 and the second air supply port 12, and is not limited to one method.

[0074] Among them, in the first switching state, the switching component switches so that the airflow introduced into the first air duct 21 by the first fan 31 is sent out from the first air supply port 11 instead of the second air supply port 12. In the second switching state, the switching component switches so that the airflow introduced into the first air duct 21 by the first fan 31 is sent out from the second air supply port 12 instead of the first air supply port 11.

[0075] For example, when a large area of ​​air supply is required, combined with Figure 5 and Figure 6 As shown, the switching component is switched to the first switching state, and the first fan 31 and the second fan 32 both work, so that the first air duct 21 forms an airflow and is delivered from the first air supply port 11, and the second air duct 22 forms an airflow and is delivered from the second air supply port 12, thereby presenting a large-scale air supply effect through the first air supply port 11 and the second air supply port 12.

[0076] For example, when long-distance air supply is required, such as Figure 1 and Figure 7As shown, the switching component is switched to the second switching state, and the first fan 31 and the second fan 32 both work, so that the first air duct 21 forms an airflow and is delivered from the second air supply port 12, and the second air duct 22 forms an airflow and is also delivered from the second air supply port 12, so that the second air supply port 12 can present a long-distance air supply effect.

[0077] For example, when conventional air supply is required, the first fan 31 can be turned off and only the second fan 32 works. The first air duct 21 does not form airflow, while the second air duct 22 forms airflow and sends it out from the second air supply port 12, thereby reducing energy consumption and meeting conventional needs.

[0078] The present application is not limited to this. For example, in a further embodiment, the switching component may further have a third switching state. In the third switching state, the switching component switches so that the airflow introduced into the first air duct 21 by the first fan 31 is respectively delivered from the first air supply port 11 and the second air supply port.

[0079] For example, when large-scale air supply and long-distance air supply are required, the switching component switches to the third switching state, and the first fan 31 and the second fan 32 both work, so that the first air duct 21 forms an airflow and sends it out from the first air supply port 11 and the second air supply port 12 respectively, and the second air duct 22 forms an airflow and sends it out from the second air supply port 12, thereby presenting a large-scale air supply effect through the first air supply port 11 and the second air supply port 12, and a long-distance air supply effect of the second air supply port 12.

[0080] Thus, according to the air conditioner 100 of the embodiment of the present application, by setting the first air duct 21, the second air duct 22 and the switching component as above, and introducing the first fan 31 and the second fan 32, it is possible to switch at least a large-scale air supply mode in which the first air duct 21 supplies air from the first air supply port 11 and the second air duct 22 supplies air from the second air supply port 12, and a long-distance air supply mode in which both the first air duct 21 and the second air duct 22 supply air from the second air supply port 12, these two unconventional air supply modes, so as to provide more air supply effect options, and whether it is large-scale air supply or long-distance air supply, since both the first fan 31 and the second fan 32 are used at the same time, the air supply effect can be more obvious. Moreover, the structure of the air conditioner 100 is relatively simple and easy to manufacture.

[0081] In some embodiments of the present application, the switching component includes a first switching device 41 and a second switching device 42, combined with Figure 5 The first switching device 41 is used to switch the switch state of the first air outlet 11, combined with Figure 7 The second switching device 42 is used to switch the on / off state of the communication path S between the first air duct 21 and the second air supply port 12 .

[0082] The first switching device 41 can at least switch between a first state and a second state. In the first state, Figure 2 As shown, the first switching device 41 opens the first air outlet 11, and the first air outlet 11 is in an open state; in the second state, as shown Figure 1 As shown, the first switching device 41 closes the first air supply port 11, and the first air supply port 11 is in a closed state.

[0083] The second switching device 42 can at least switch between a third state and a fourth state. In the third state, Figure 6 As shown, the second switching device 42 blocks the communication path S, and the first air duct 21 cannot blow air to the second air outlet 12; in the fourth state, as shown Figure 7 As shown, the second switching device 42 opens the communication path S, and the first air duct 21 can blow air to the second air outlet 12 .

[0084] For example, when a large area of ​​air supply is required, combined with Figure 5 and Figure 6 As shown, the first switching device 41 switches to the first state to open the first air supply port 11, and the second switching device 42 switches to the third state to block the connecting path S, the first air supply port 11 and the second air supply port 12 are both in an open state, and the first fan 31 and the second fan 32 are both working, so that the first air duct 21 forms an airflow and is delivered from the first air supply port 11, and the second air duct 22 forms an airflow and is delivered from the second air supply port 12, thereby presenting a large-scale air supply effect through the first air supply port 11 and the second air supply port 12.

[0085] For example, when long-distance air supply is required, such as Figure 1 and Figure 7 As shown, the first switching device 41 switches to the second state to close the first air supply outlet 11, and the second switching device 42 switches to the fourth state to open the connecting path S. The first air supply outlet 11 is in a closed state, and the second air supply outlet 12 is in an open state. The first fan 31 and the second fan 32 both work to form an airflow in the first air duct 21 and send it out from the second air supply outlet 12 through the connecting path S, and the second air duct 22 forms an airflow and sends it out from the second air supply outlet 12, so that the second air supply outlet 12 can present a long-distance air supply effect.

[0086] Of course, the present application is not limited thereto. For example, in some embodiments of the present application, the first switching device 41 includes a first valve, and the first valve continuously moves (e.g., moves or rotates) between a first position and a second position to switch between a first state and a second state. The first position is the first state, and the second position is the second state. At this time, the first switching device 41 may also have an intermediate state in which the first valve is located between the first position and the second position. Similarly, the second switching device 42 includes a second valve, and the second valve continuously moves (e.g., moves or rotates) between a third position and a fourth position to switch between a third state and a fourth state. The third position is the third state, and the fourth position is the fourth state. At this time, the second switching device 42 may also have an intermediate state in which the second valve is located between the third position and the fourth position.

[0087] It is worth noting that the type of the air conditioner 100 according to the embodiment of the present application is not limited, and can be an integrated air conditioner or a split air conditioner. The integrated air conditioner can include a window air conditioner or a mobile air conditioner, etc., and the split air conditioner can include a wall mounted air conditioner or a cabinet air conditioner, etc. When the type of the air conditioner 100 is determined, the shape of the housing assembly 1, as well as the number and distribution positions of the first air outlet 11 and the second air outlet 12 can be adaptively designed.

[0088] For example, Figure 1 As shown, the air conditioner 100 is an air conditioner cabinet, that is, the length direction of the shell assembly 1 extends vertically, the length direction of the second air supply port 12 extends vertically, there is one second air supply port 12 and it is located on the front side of the air conditioner 100, or there are two second air supply ports 12 and they are disposed on the left and right sides of the front of the air conditioner 100, the first air supply port 11 is arranged higher than the second air supply port 12, and the first air supply port 11 is arranged on the top surface or the upper front side of the air conditioner 100, the first fan 31 is a centrifugal fan, and the second fan 32 is a cross-flow fan.

[0089] When long-distance air supply is required, the centrifugal fan allows the airflow to enter the first air duct 21, and the cross-flow fan allows the airflow to enter the second air duct 22. The first switching device 41 is used to close the upper first air supply port 11, and the second switching device 42 is used to open the connecting path S between the first air duct 21 and the second air supply port 12. At this time, the airflow entering the first air duct 21 is not sent out through the upper first air supply port 11, but the airflow entering the first air duct 21 and the airflow entering the second air duct 22 are both sent out through the second air supply port 12, thereby increasing the air supply distance of the second air supply port 12 and achieving the effect of long-distance air supply.

[0090] When full-area air supply is required, the centrifugal fan allows the airflow to enter the first air duct 21, and the cross-flow fan allows the airflow to enter the second air duct 22. The first switching device 41 is used to open the upper first air supply port 11, and the second switching device 42 is used to block the connecting path S between the first air duct 21 and the second air supply port 12. At this time, the airflow entering the first air duct 21 is sent out through the upper first air supply port 11, and the airflow entering the second air duct 22 is sent out through the second air supply port 12, thereby achieving the effect of full-area air supply.

[0091] Furthermore, since centrifugal fans have the characteristics of large air volume and strong wind force compared with cross-flow fans, matching the centrifugal fan with the first air supply outlet 11 located at the top is beneficial to enabling the first air supply outlet 11 located at the top to effectively discharge air in the full-area air supply mode, and in the long-distance air supply mode, the airflow in the first air duct 21 can drive the airflow in the second air duct 22 to be delivered over a long distance; and the cross-flow fan has the characteristics of small air volume and weak wind force compared with the centrifugal fan, matching the cross-flow fan with the second air supply outlet 12 located at the front can reduce the feeling of direct wind in the full-area air supply mode, and the axial length of the cross-flow fan can match the vertical extension length of the second air supply outlet 12, so that the air supply of the second air supply outlet 12 can be relatively uniform within the entire vertical length range.

[0092] It is worth noting that, regardless of the type of the air conditioner 100, the first air supply port 11 can be arranged on the top surface or the upper front side of the air conditioner 100, the second air supply port 12 is one and located in the center of the front side of the air conditioner 100, or the second air supply port 12 is two and is located on the left and right sides of the front of the air conditioner 100. Thus, when supplying air over long distances, the first air supply port 11 at the top or the upper front side does not discharge air, and the second air supply port 12 at the center of the front side or the left and right sides of the front discharges air, which is conducive to realizing long-distance air supply forward or sideways to the front, and better meeting the demand for long-distance air supply. When supplying air over the entire area, the first air supply port 11 at the top or the upper front side discharges air, and the second air supply port 12 at the center of the front side or the left and right sides of the front also discharges air, which is conducive to realizing full-area air supply forward or sideways to the front, and upward or front and upper, and better meeting the full-area air supply requirements.

[0093] In addition, when a centrifugal fan is used, since the centrifugal fan has the characteristics of large air volume and strong wind force, the first air outlet 11 is arranged on the top surface of the air conditioner 100, which can better prevent the air from the first air outlet 11 from blowing directly on the user and causing discomfort to the user. The second air outlet 12 is arranged in two and is arranged on the left and right sides of the front of the air conditioner 100, which is conducive to achieving the effect of surrounding air supply from the left and right sides, increasing the air supply range, and improving the uniformity of indoor temperature regulation.

[0094] In some embodiments of the present application, a first switch door is provided at the first air outlet 11. Thus, the first switch door can be used to control the switch of the first air outlet 11, so that when the first air outlet 11 is not needed to supply air, the first air outlet 11 is closed to ensure the cleanliness of the air conditioner 100. Figure 1 and Figure 2 The first switch door is used as the first switching device 41, so that the first switch door of the first air supply port 11 is used as the first switching device 41 for switching the switch state of the first air supply port 11, thereby eliminating the need for additional components and simplifying the overall structure.

[0095] Example, combined Figure 3 The first switch door includes a first driver 411 and a first rotating door 412. The first driver 411 drives the first rotating door 412 to rotate to close the first air outlet 11 or open the first air outlet 11. Thus, the first rotating door 412 realizes state change by rotating, the setting is simple and easy to control, and the space required for movement is small. Of course, the present application is not limited to this. For example, the first switch door can also be set as a sliding door that moves horizontally, which will not be described here.

[0096] In some embodiments of the present application, a second switch door is provided at the second air supply port 12 (the second switch door is not shown in the figure). Thus, the second switch door can be used to control the switch of the second air supply port 12, so that when the second air supply port 12 is not needed to supply air, the second air supply port 12 is closed to ensure the cleanliness of the air conditioner 100.

[0097] In some embodiments of the present application, Figure 8 and Fig. 9 As shown, the second air outlet 12 is provided with a wind adjustment device 7, and the wind adjustment device 7 has a plurality of ventilation holes 71. For example, the wind adjustment device 7 can be a third air guide blade, combined with Figure 6-Figure 8 The third air guide blade has an air guiding state with an acute angle or an obtuse angle with the air supply direction of the second air supply port 12. In the air guiding state, the airflow flowing to the second air supply port 12 is sent out along the surface of the third air guide blade, or sent out between two adjacent third air guide blades; combined Fig. 9 The third air guide blade also has a shielding state that is substantially perpendicular to the air supply direction of the second air supply port 12. In the shielding state, the airflow flowing to the second air supply port 12 is sent out from the ventilation holes 71 on the third air guide blade, thereby reducing the wind feeling of the air supply.

[0098] Or, for another example, the second opening and closing door can be used as the wind sense adjusting device 7. Since the second opening and closing door can avoid opening the second air supply port 12, and can also block and close the second air supply port 12, when the second air supply port 12 is avoided to be opened, the airflow flowing to the second air supply port 12 is directly delivered from the second air supply port 12, and when the second air supply port 12 is blocked and closed, the airflow flowing to the second air supply port 12 is delivered from the ventilation holes 71 on the second opening and closing door, thereby reducing the wind sense of the air supply.

[0099] For example, when a large air volume and low wind sense air supply are required, the centrifugal fan allows the air flow to enter the first air duct 21, and the crossflow fan allows the air flow to enter the second air duct 22. The first switching device 41 is used to open the upper first air supply port 11, and the second switching device 42 is used to block the communication path S between the first air duct 21 and the second air supply port 12. The wind sense adjustment device 7 is adjusted to a state of at least partially blocking the second air supply port 12. At this time, the air flow entering the second air duct 22 is sent out through the ventilation hole 71 at the second air supply port 12, and the wind sense is relatively low. The air flow entering the first air duct 21 is sent out through the upper first air supply port 11 to supplement the air volume, thereby achieving the effect of large air volume and low wind sense. For example Figure 2 shown.

[0100] In some embodiments of the present application, Figure 6 and Figure 7 As shown, the air conditioner 100 includes a mixed air duct 23, combined with Fig.10 and Fig.11 The outlet of the mixed air duct 23 is connected to the second air supply port 12 , and the mixed air duct 23 has a first inlet 231 connected to the first air duct 21 and a second inlet 232 connected to the second air duct 22 . The second switching device 42 is used to switch the on-off state of the first air duct 21 and the first inlet 231 .

[0101] In this way, the second air duct 22 can be connected to the second air supply port 12 through the air mixing duct 23, and the first air duct 21 can be selectively connected to the second air supply port 12 through the air mixing duct 23. At this time, the path from the first air duct 21 to the air mixing duct 23 can be used as the connecting path S, such as Figure 6 As shown, when the second switching device 42 is switched to block the first air duct 21 and the first inlet 231, the communication path S is blocked, and the airflow of the first air duct 21 cannot be supplied to the air mixing duct 23. Figure 7 As shown, when the second switching device 42 is switched to connect the first air duct 21 with the first inlet 231 , the communication path S is opened, and the airflow of the first air duct 21 can be supplied to the air mixing duct 23 , and thus can be delivered from the second air supply port 12 .

[0102] Therefore, by setting the above-mentioned air mixing duct 23, it is possible to simply and effectively realize "the second air duct 22 connected to the second air supply port 12, there is a connecting path S between the first air duct 21 and the second air supply port 12, and the second switching device 42 is used to switch the on-off state of the connecting path S", and it is convenient to set and control the second switching device 42. In addition, the air mixing duct 23 is set so that the air flow of the second air duct 22 is not disturbed by the air flow of the first air duct 21, thereby ensuring the ventilation efficiency of the second air duct 22.

[0103] Of course, the present application is not limited to this, that is, the air conditioner 100 may also not include the mixed air duct 23. For example, in other embodiments of the present application, the second air duct 22 may be connected to the first air duct 21 through a connecting port, and the second switching device 42 is used to switch the switching state of the connecting port. When the second switching device 42 closes the connecting port, the connecting path S is blocked, and the airflow of the first air duct 21 cannot be supplied to the second air duct 22. When the second switching device 42 opens the connecting port, the connecting path S is opened, and the airflow of the first air duct 21 can be supplied to the second air duct 22 and delivered from the second air supply port 12 together with the airflow of the second air duct 22. No further details will be given here.

[0104] In some embodiments of the present application, Fig.10 As shown, when the air conditioner 100 includes the above-mentioned air mixing duct 23, there can be two second air supply ports 12. In this case, there are also two air mixing ducts 23 and they are respectively arranged corresponding to the two second air supply ports 12. Figure 4 and Figure 5 The second air duct 22 may include two air outlet branches 221, and the two air outlet branches 221 are respectively connected to the second inlets 232 of the two air mixing ducts 23, and the first air duct 21 includes two connecting sections 212, and the outlets of the two connecting sections 212 are respectively connected to the first inlets 231 of the two air mixing ducts 23. Therefore, by setting the above structure, the air outlet range angle can be increased, which is conducive to improving the uniformity of temperature regulation in a larger range.

[0105] Exemplarily, the two air mixing ducts 23 are distributed on the left and right, the air mixing duct on the left corresponds to the second air supply port 12 on the left, the connecting section 212 on the left is connected to the first inlet 231 of the air mixing duct 23 on the left, and the air outlet branch 221 on the left is connected to the second inlet 232 of the air mixing duct 23 on the left; the air mixing duct 23 on the right corresponds to the second air supply port 12 on the right, the air outlet branch 221 on the right is connected to the second inlet 232 of the air mixing duct 23 on the right, and the connecting section 212 on the right is connected to the first inlet 231 of the air mixing duct 23 on the right. In this way, when both second air supply ports 12 are supplying air outward, the air outlet range angle can be increased, which is conducive to improving the uniformity of temperature regulation in a larger range.

[0106] In addition, since the two air mixing ducts 23 can obtain the airflow provided by the first air duct 21 and the second air duct 22 respectively, when the second switching device 42 switches the connecting path S to be opened, the two air mixing ducts 23 can realize long-distance air supply from the two second air supply ports 12.

[0107] In some embodiments, Fig.10 As shown, the length direction of each second air outlet 12 extends vertically. The length direction of the connecting section 212 and the air outlet branch 221 extends vertically, and the second fan 32 is a cross-flow fan with an axial direction extending vertically. Figure 4 As shown, the inlets of the two outlet branches 221 converge at the outlet of the cross-flow fan, the two second air outlets 12 are spaced apart in the horizontal direction (e.g., left-right direction), and the two connecting sections 212 are located on both sides of the second air duct 22 in the horizontal direction (e.g., left-right direction). For example, when the air conditioner 100 is a cabinet air conditioner, the vertical direction is the up-down direction, and the horizontal direction is the left-right direction.

[0108] Thus, by providing two second air outlets 12 as described above, the air supply range of the air conditioner 100 in the horizontal direction and in the vertical direction can be increased. Furthermore, by providing two connecting sections 212 on both sides of the second air duct 22, the inlets of the two air outlet branches 221 can be easily converged at the outlet of the crossflow fan, thereby reducing the difficulty of forming the second air duct 22 and simplifying the structure. Moreover, since the inlets of the two air outlet branches 221 converge at the outlet of the crossflow fan, the crossflow fan only needs to be provided with a single crossflow fan wheel, thereby reducing the cost.

[0109] Of course, the present application is not limited thereto. For example, the crossflow fan may also include two crossflow impellers. In this case, the inlets of the two air outlet branches 221 extend to the two crossflow impellers respectively, and do not need to converge at the outlet of the crossflow fan. In addition, it is understandable that when the air conditioner includes only one second air supply port 12, only a single air outlet branch 221 is required, which will not be described in detail here.

[0110] In some embodiments, Figure 4-Figure 7 As shown, the first air duct 21 further includes an air outlet section 211 disposed above the connecting section 212, the air outlet section 211 is connected to the upper ends of the two connecting sections 212, and the air outlet section 211 is connected to the first air supply port 11, as shown in FIG. Fig.14As shown, the size of the air outlet section 211 in the lateral direction (e.g., left-right direction) is at least partially gradually reduced from bottom to top. Specifically, the upper ends of the two connecting sections 212 are both connected to the air outlet section 211. Since the two connecting sections 212 are located on both sides of the second channel 22 in the lateral direction, the size of the air outlet section 211 in the lateral direction needs to be relatively larger to facilitate connection with the two connecting sections 212. In some embodiments of the present application, by gradually reducing the lateral size of at least one section of the air outlet section 211 from the bottom from bottom to top, the air outlet speed can be increased, so that the air outlet distance of the first air outlet can be increased.

[0111] In some embodiments, Figure 3-Figure 11 As shown, the housing assembly 1 includes a panel member 13, the panel member 13 defines an air mixing duct 23, and the second air supply port 12 is formed on the panel member 13. The air conditioner 100 also includes an air duct assembly 5, the air duct assembly 5 is assembled in the housing assembly 1, and the air duct assembly 5 defines a first air duct 21 and a second air duct 22. Thus, the reliability of the connection between the second air supply port 12 and the air mixing duct 23 can be ensured, and the structure of the air duct assembly 5 can be simplified, and the processing difficulty of the air duct assembly 5 can be reduced.

[0112] Exemplarily, the panel member 13 may be provided with an inwardly recessed portion, the concave cavity formed by the recessed portion forms the air mixing duct 23, and the concave entrance of the recessed portion forms the second air supply port 12, thereby facilitating processing.

[0113] In some embodiments, Fig.12 and Fig.13 As shown, the second switching device 42 includes a second driver 421 and a second rotating door 422, Figure 6 and Figure 7 The second rotating door 422 is disposed in the first air duct 21, and the second driver 421 drives the second rotating door 422 to rotate to block the first inlet 231 or to open the first inlet 231. When the first inlet 231 is blocked, the airflow in the first air duct 21 cannot be sent into the air mixing duct 23 through the first inlet 231, and when the first inlet 231 is opened, the airflow in the first air duct 21 can be sent into the air mixing duct 23 through the first inlet 231.

[0114] Therefore, the second rotating door 422 does not occupy the space of the air mixing duct 23, and the second rotating door 422 does not affect the air supply of the air mixing duct 23 no matter where it is, thereby ensuring the air supply effect of the second air supply port 12. Moreover, the second rotating door 422 realizes state change by rotating, is simple to set and easy to control, and requires less space for movement.

[0115] Of course, the present application is not limited thereto. For example, in other embodiments of the present application, the second rotating door 422 may also be disposed at other locations, such as in the air mixing duct 23. In addition, the on-off state of the first duct 21 and the first inlet 231 may also be switched by translation or other means.

[0116] In some embodiments, Figure 1-Figure 3 As shown, the length direction of the second air supply port 12 extends vertically, the first air supply port 11 is arranged higher than the second air supply port 12, the first fan 31 is a centrifugal fan, and the second fan 32 is a cross-flow fan extending axially vertically, and the centrifugal fan is arranged lower than the cross-flow fan (such as the centrifugal fan is located directly below or diagonally below the cross-flow fan).

[0117] Therefore, setting the centrifugal fan lower than the cross-flow fan can avoid the centrifugal fan occupying the space above the cross-flow fan, which is beneficial to increase the height of the upper end of the second air supply port 12 corresponding to the cross-flow fan, and arranging the centrifugal fan and the cross-flow fan in the bottom-up direction can make full use of the vertical space in the air conditioner 100, which is beneficial to improve space utilization and make the component layout in the air conditioner 100 compact, and setting the centrifugal fan lower than the cross-flow fan can lower the center of gravity of the whole machine and improve the stability of the whole machine.

[0118] In some embodiments, Figure 4-Figure 7 As shown, the first air duct 21 includes a connecting section 212 and an air outlet section 211. The connecting section 212 and the second air duct 22 are both extended in the vertical direction in the length direction and are consistent with the vertical height range occupied by the second air supply port 12. The connecting section 212 is connected to the second air supply port 12 through a connecting path S (for example, it can be connected through, but not limited to, the above-mentioned air mixing duct 23). The lower end of the connecting section 212 is connected to the outlet of the centrifugal fan. The air outlet section 211 is located above the connecting section 212 and is connected to the upper ends of the first air supply port 11 and the connecting section 212, respectively. It is worth noting that the connecting section 212 described in this embodiment can be used in the embodiment in which the above-mentioned air conditioner 100 includes the air mixing duct 23, and may not be used in the embodiment in which the above-mentioned air conditioner 100 includes the air mixing duct 23.

[0119] Therefore, by setting the first air duct 21 to include an air outlet section 211 and a connecting section 212 arranged vertically, the connecting section 212 can not only be used to supply air to the air outlet section 211 to meet the demand for air supply from the first air supply port 11 above, but the connecting section 212 can also meet the demand for air supply to the second air supply port 12 within the entire height range, thereby improving the uniformity of long-distance air supply.

[0120] In some embodiments of the present application, the switching component may not include the first switching device 41 provided at the first air outlet 11, for example, it may include a third switching device 43 (such as Fig.17 and Fig.18 As shown), it also includes the second switching device 42 of any of the above embodiments, and the third switching device 43 is used to switch the on-off state of the connecting section 212 and the air outlet section 211 (as shown in FIG. Fig.17 As shown), when the third switching device 43 blocks the air outlet section 211 and the connecting section 212 (as shown Fig.18 As shown), the airflow of the connecting section 212 cannot be delivered to the air outlet section 211, and thus cannot be delivered from the first air supply port 11. When the third switching device 43 opens the air outlet section 211 and the connecting section 212, the airflow of the connecting section 212 can be delivered to the air outlet section 211, and thus can be delivered from the first air supply port 11.

[0121] Exemplarily, the third switching device 43 may include a rotating door and a driving motor, etc. The driving motor drives the rotating door to determine whether to cut off the connecting position between the connecting section 212 and the air outlet section 211 .

[0122] In some embodiments of the present application, Figure 3-Figure 5 As shown, the air conditioner 100 includes an air duct assembly 5, and the air duct assembly 5 includes a first air outlet frame 51 and a second air outlet frame 52 arranged in a vertical manner, the first air outlet frame 51 defines an air outlet section 211, and the second air outlet frame 52 defines a second air duct 22 and a connecting section 212. Thus, the structure of the air duct assembly 5 is simple, and the air outlet section 211, the second air duct 22 and the connecting section 212 can be easily processed, and the second air duct 22 and the connecting section 212 can be well ensured to be connected with the second air supply port 12. It is worth noting that the air duct assembly 5 described in this embodiment can be used in the embodiment in which the air conditioner 100 includes the air mixing duct 23, and can also not be used in the embodiment in which the air conditioner 100 includes the air mixing duct 23.

[0123] The specific structural form of the second air outlet frame 52 is not limited, for example, it can be composed of a plurality of parts, so as to define the second air duct 22 and the connecting section 212. Figure 3 and Figure 4 The second air outlet frame 52 may include a first part 521 and a second part 522 that are assembled and connected. The first part 521 is integrally formed with the volute of the crossflow fan. The second part 522 is an integrally formed part and defines a second air duct 22. A connecting section 212 is defined between the first part 521 and the second part 522.

[0124] Thus, the second air outlet frame 52 has a simple structure, is easy to process and assemble, and by setting the first part 521 to be integrally formed with the volute of the crossflow fan, the number of parts can be reduced and the assembly efficiency of the whole machine can be improved. When the second air duct 22 includes two air outlet branches 221, the two air outlet branches 221 can be defined by the second part 522, so that it is easy to process and the relative position accuracy of the two air outlet branches 221 can be easily ensured.

[0125] In some embodiments of the present application, when the first air outlet 11 is disposed on the top surface or the upper front part of the air conditioner 100, the second air outlet 12 is one and is located at the center of the front part of the air conditioner 100, or the second air outlet 12 is two and is disposed on the left and right sides of the front part of the air conditioner 100, Fig.14 The air conditioner 100 may include a first air guide device 61, the first air guide device 61 includes a plurality of first air guide blades 611 disposed in the first air duct 21 and spaced apart in a lateral direction (eg, left-right direction), Fig.12 and Fig.13 The air conditioner 100 includes a second air guide device 62, which includes a plurality of second air guide blades 621 disposed in the second air duct 22 and spaced apart in a vertical direction (eg, up and down direction).

[0126] Therefore, the first air guide device 61 can adjust the air supply effect of the upper first air supply outlet 11 in the horizontal direction (for example, the left and right direction), and the second air guide device 62 can adjust the air supply effect of the second air supply outlet 12 in the vertical direction (for example, the up and down direction), thereby better expanding the air supply range in the horizontal and vertical directions.

[0127] It is worth noting that the structure of the first air guide device 61 is not limited to this, for example, it can also include a first connecting rod 612 and a first motor 613, the first motor 613 drives one of the first air guide blades 611 to rotate, and the first connecting rod 612 links the multiple first air guide blades 611 to rotate synchronously, so as to achieve driving air guiding. Similarly, the structure of the second air guide device 62 is not limited to this, for example, it can also include a second connecting rod and a second motor, the second motor drives one of the second air guide blades 621 to rotate, and the second connecting rod links the multiple second air guide blades to rotate synchronously, so as to achieve driving air guiding.

[0128] Of course, the present application is not limited thereto. For example, in other embodiments of the present application, the air conditioner 100 may also include only at most one of the first air guide device 61 and the second air guide device 62 .

[0129] In some embodiments of the present application, when the wind sense adjustment device 7 is a third guide blade, the length direction of the third guide blade can extend along the length direction of the second air supply outlet 12, and multiple guide blades can be arranged at intervals along the horizontal direction, so that when the second guide blade 621 and the third guide blade are combined, the wind guiding effect can be better achieved in the horizontal and vertical directions.

[0130] For example, in some embodiments, Fig.15 and Fig.16 As shown, when the panel member 13 is formed with an air mixing duct 23, the third air guide blade can be installed on the panel member 13 and located in the air mixing duct 23, for example, 1-3 third air guide blades are provided in each air mixing duct 23. In addition, the structure of the wind sense adjustment device 7 is not limited thereto, for example, it can also include a third connecting rod and a third motor, the third motor drives one of the third air guide blades 621 to rotate, and the third connecting rod links multiple third air guide blades to rotate synchronously, thereby realizing driving the air guide.

[0131] In addition, in order to improve safety, combined Figure 4 and Fig.15 A protective net or a protective grille may be provided at at least one of the first inlet and the second inlet of the air mixing duct.

[0132] In some embodiments of the present application, Figure 3 and Figure 4 As shown, the air conditioner 100 may further include a heat exchange component 8, the inlet of the first fan 31 and the inlet of the second fan 32 correspond to different parts of the same heat exchange component 8, the outlet of the first fan 31 corresponds to the first air duct 21, and the outlet of the second fan 32 corresponds to the second air duct 22. In this way, the air conditioner 100 only needs to be provided with an integral heat exchange component 8, along the air flow direction, the first fan 31 is located upstream of the first air duct 21, the second fan 32 is located upstream of the second air duct 22, and the heat exchange component 8 is located both upstream of the first fan 31 and upstream of the second fan 32. In this way, the number of heat exchange components 8 can be reduced, the assembly efficiency can be improved, and the structure of the air conditioner 100 can be simplified.

[0133] Of course, the present application is not limited to this. In other embodiments of the present application, the heat exchange component 8 may also include two heat exchangers arranged at intervals, the inlet of the first fan 31 corresponds to one of the heat exchangers, and the inlet of the second fan 32 corresponds to the other heat exchanger, so that the relative positions of the two heat exchangers can be adjusted according to the positions of the first fan 31 and the second fan 32, thereby realizing flexible setting of the positions of the first fan 31 and the second fan 32.

[0134] In some embodiments of the present application, Figure 1-Figure 3As shown, the housing assembly 1 includes a panel member 13, a rear box body 14, a base 15 and a top cover 16. The panel member 13 is arranged at the front side of the rear box body 14, the base 15 is arranged below the panel member 13 and the rear box body 14, and the top cover 16 is arranged above the panel member 13 and the rear box body 14.

[0135] For example, Figure 1-Figure 3 As shown, the front side of the top cover 16 has a first air supply port 11 whose length direction extends in the left-right direction, and the panel member 13 has a second air supply port 12. There are two second air supply ports 12 and they are spaced apart in the left-right direction, one supplies air to the left front, and the other supplies air to the right front. The length direction of each second air supply port 12 extends vertically, and the upper end of the second air supply port 12 is higher than the height center of the shell assembly 1, and the lower end of the second air supply port 12 is lower than the height center of the shell assembly 1.

[0136] In some embodiments of the present application, Figure 4 and Fig.19 As shown, the second portion 522 of the second air outlet frame 52 can be fixed to the panel member 13 by a snap-on assembly and / or a threaded connector, so as to ensure the reliability of the connection between the air mixing duct 23 and the second air duct 22 and the connecting section 212. Fig. 20 and Fig.21 Alternatively, the second portion 522 of the second air outlet frame 52 may be assembled with the first portion 521 and then fixed together on the rear box body 14 .

[0137] In some embodiments of the present application, Fig. 20 and Fig.21 As shown, the first air outlet frame 51 can be overlapped on the second air outlet frame 52 from top to bottom, and the first air outlet frame 51 can be fixed on the second air outlet frame 52 and / or the rear box body 14 through a snap-on assembly and / or a threaded connector. Fig. 20 and Fig.21 As shown, the bottom of the first air outlet frame 51 may have an overlapping portion 511 , and the top of the second air outlet frame 52 may have a supporting portion 523 , and the overlapping portion 511 is overlapped on the supporting portion 523 .

[0138] In some embodiments of the present application, Figure 22-Figure 24 As shown, the top cover 16 and the first air outlet frame 51 are separate parts and are assembled together. The top cover 16 has a first air supply port 11, and the top cover 16 has an air duct portion 161 extending downward. The upper end of the air duct portion 161 is correspondingly connected to the first air supply port 11. During assembly, the air duct portion 161 is inserted downward into the slot 512 at the top of the first air outlet frame 51.

[0139] In order to improve the efficiency of plugging, such as Figure 22-Figure 24As shown, a guide rib 513 may be provided on the periphery of the slot 512 of the first air outlet frame 51 to guide the lower end of the air duct portion 161 to be smoothly inserted into the slot 512 .

[0140] For example, Figure 22-Figure 24 As shown, the slot 512 may be an annular groove, so that the stability of the limit can be improved when the lower end of the air duct portion 161 is inserted into the slot 512. Of course, the present application is not limited thereto, and for example, an annular protrusion may be used to replace the slot 512, so that the lower end of the air duct portion 161 is set to be sleeved outside the annular protrusion, which also plays the role of limiting.

[0141] In some embodiments of the present application, Fig.25 and Fig.26 As shown, the front surface of the first air outlet frame 51 (i.e., the side surface facing the panel member 13) can be provided with an inwardly recessed recess 514 to accommodate components such as a display module, thereby improving the overall structural compactness of the air conditioner 1000.

[0142] Hereinafter, an air conditioner 100 according to a specific embodiment of the present application will be described with reference to the accompanying drawings.

[0143] like Figure 1-Figure 3 As shown, the air conditioner 100 comprises: a housing assembly 1, an air duct assembly 5, a first fan 31, a second fan 32 and a heat exchange component 8. The air conditioner 100 is a cabinet unit, the length direction of the housing assembly 1 extends vertically, and the housing assembly 1 comprises a panel member 13, a rear box 14, a base 15 and a top cover 16. The panel member 13 is arranged at the front side of the rear box 14, the base 15 is arranged below the panel member 13 and the rear box 14, and the top cover 16 is arranged above the panel member 13 and the rear box 14. The top cover 16 has a first air supply port 11, and the panel member 13 has a second air supply port 12. There are two second air supply ports 12 and they are spaced apart in the left and right directions, one of which supplies air to the left front and the other supplies air to the right front. The length direction of each second air supply port 12 extends vertically, and the upper end of the second air supply port 12 is higher than the height center of the housing assembly 1, and the lower end of the second air supply port 12 is lower than the height center of the housing assembly 1.

[0144] Combination Figure 4The panel member 13 is respectively recessed inward from the position of each second air supply port 12 to form a recessed portion, and the recessed portion forms a concave cavity to form an air mixing duct 23, so that the outlet of the air mixing duct 23 is connected to the second air supply port 12, and the vertical length of the air mixing duct 23 is consistent with the vertical length of the second air supply port 12. The air mixing duct 23 has a first inlet 231 and a second inlet 232. The length direction of the first inlet 231 extends vertically, and the length direction of the second inlet 232 also extends vertically. The second inlet 232 is located on the side of the first inlet 231 close to the center of the panel member 13. For example, the cross section of the air mixing duct 23 is a triangle, and the second air supply port 12, the first inlet 231, and the second inlet 232 respectively occupy the positions of the three sides of the triangle.

[0145] Combination Figure 3-Figure 6 The air duct assembly 5 is assembled in the shell assembly 1, and the air duct assembly 5 defines a first air duct 21 and a second air duct 22. The first air duct 21 includes an air outlet section 211 and a connecting section 212 arranged up and down. The air duct assembly 5 includes a first air outlet frame 51 and a second air outlet frame 52. The first air outlet frame 51 is arranged on the top of the second air outlet frame 52. The first air outlet frame 51 defines the air outlet section 211, and the second air outlet frame 52 defines the second air duct 22 and the connecting section 212. The second air outlet frame 52 includes a first part 521 and a second part 522 assembled and connected. The first part 521 is integrally formed with the volute of the second fan 32, and the second part 522 is an integrally formed part and defines the second air duct 22. The connecting section 212 is defined between the first part 521 and the second part 522.

[0146] Among them, the second air outlet frame 52 defines two connecting sections 212, and the second air duct 22 includes two air outlet branches 221. The two connecting sections 212 are located on the left and right sides of the second air duct 22. The length directions of the connecting sections 212 and the air outlet branches 221 extend vertically, and the connecting sections 212 and the air outlet branches 221 are consistent with the vertical height range occupied by the mixed air duct 23. The outlets of the two connecting sections 212 are respectively connected to the first inlets 231 of the two mixed air ducts 23, and the outlets of the two air outlet branches 221 are respectively connected to the second inlets 232 of the two mixed air ducts 23.

[0147] The second fan 32 is a crossflow fan, which includes a single crossflow fan wheel with an axis extending vertically, and the inlets of the two air outlet branches 221 converge at the outlet of the crossflow fan. The first fan 31 is a centrifugal fan and is located below the crossflow fan. The lower end of the connecting section 212 is connected to the outlet of the centrifugal fan, and the upper end of the connecting section 212 is connected to the air outlet section 211, and the air outlet section 211 is connected to the first air supply port 11. Among them, the top cover 16 and the first air outlet frame 51 can be an integral part or a split part. The inlet of the crossflow fan and the inlet of the centrifugal fan correspond to different parts of the same heat exchange component 8.

[0148] The centrifugal fan works to blow air to the two connecting sections 212. The air entering the connecting section 212 can enter the air mixing duct 23 through the first inlet 231 and then be sent out from the second air supply ports 12 on the left and right sides of the front. The air entering the connecting section 212 can also enter the air outlet section 211 upward and then be sent out from the top first air supply port 11. The cross-flow fan works to blow air to the two air outlet branches 221. The air entering the air outlet branch 221 can enter the air mixing duct 23 through the second inlet 232 and then be sent out from the second air supply ports 12 on the left and right sides of the front.

[0149] In this embodiment, combined with Figure 5-Figure 7 The air conditioner 100 further includes a first switching device 41 and a second switching device 42. The first switching device 41 includes a first switch door provided at the first air outlet 11, and the first switch door is used to switch the switch state of the first air outlet 11. The second switching device 42 includes a second rotating door 422, and the second rotating door 422 is provided in the first air duct 21, and the second rotating door 422 is rotated to block the first inlet 231 or open the first inlet 231, thereby switching the on-off state of the first air duct 21 and the first inlet 231.

[0150] like Figure 8-Figure 14 As shown, the air conditioner 100 also includes a first air guide device 61, a second air guide device 62 and a wind sense adjustment device 7, the first air guide device 61 includes a plurality of first air guide blades 611 arranged in the first air duct 21 and spaced apart along the left-right direction, the second air guide device 62 includes a plurality of second air guide blades 621 arranged in the second air duct 22 and spaced apart along the vertical direction. The wind sense adjusting device 7 is a third guide blade arranged at the second air supply port 12. The length direction of the third guide blade extends vertically and is a plurality of blades arranged at the second air supply port 12 at intervals along the horizontal direction. The third guide blade has a plurality of ventilation holes 71. The third guide blade has a wind guiding state that is acute or obtuse with the air supply direction of the second air supply port 12. In the wind guiding state, the airflow flowing to the second air supply port 12 is delivered along the surface of the third guide blade, and is delivered between two adjacent third guide blades. The third guide blade also has a shielding state that is substantially perpendicular to the air supply direction of the second air supply port 12. In the shielding state, the airflow flowing to the second air supply port 12 is delivered from the ventilation holes 71 on the third guide blade, thereby reducing the wind sense of the air supply.

[0151] In summary, the first air duct 21 is a centrifugal air duct connected to the centrifugal fan, and the second air duct 22 is a cross-flow air duct connected to the cross-flow fan. The cross-flow air duct and the centrifugal air duct both extend in the vertical direction, and the two have relatively independent air flow channels, and the two share the heat exchange component 8. The air conditioner 100 is provided with air supply outlets on the left and right sides and the top of the front, respectively, wherein the air supply outlets on the left and right sides of the front are the second air supply outlets 12 and are connected to the mixed air duct 23, the mixed air duct 23 is connected to the cross-flow air duct, and can be selectively connected to the centrifugal air duct, and the centrifugal air duct is also connected to the air supply outlet on the top, i.e., the first air supply outlet 11.

[0152] The centrifugal air duct can supply air to the first air supply port 11 at the top, and can also supply air to the second air supply port 12 through the air mixing duct 23. The cross-flow air duct can supply air to the second air supply port 12 through the air mixing duct 23. When the centrifugal air duct also supplies air to the air mixing duct 23, the second air supply port 12 can present a form of mixed air outlet of the cross-flow air duct and the centrifugal air duct. When the mixed air is discharged, the high-speed airflow of the centrifugal air duct drives the airflow of the cross-flow air duct to supply air forward, so as to increase the air supply distance of the second air supply port 12.

[0153] Therefore, when long-distance air supply is required, the first air supply port 11 at the top can be closed by the first switch door, and the first inlet 231 connecting the centrifugal air duct and the air mixing duct 23 can be opened by the second rotating door 422, so that the first air duct 21 and the second air duct 22 are mixed in the air mixing duct 23, and the high-speed airflow of the centrifugal air duct drives the airflow of the crossflow air duct to be transported forward from the second air supply port 12 to the second air supply port 12 for long-distance air supply. In addition, the second air supply ports 12 on both sides discharge air together, presenting an effect of left and right surrounding air supply (for example, Figure 1 shown).

[0154] When the second rotating door 422 opens the first inlet 231 connecting the centrifugal air duct and the air mixing duct 23, and the first switch door opens the first air supply port 11 on the top, and the third air guide blade is in an air guiding state, a part of the airflow in the centrifugal air duct is sent out from the first air supply port 11 on the top, and the other part of the airflow enters the air mixing duct 23 and mixes with the airflow in the cross-flow air duct, and is sent out together from the second air supply port 12. At this time, the air conditioner 100 can present a full-area air supply effect in which air is supplied from the first air supply port 11 on the top and the second air supply ports 12 on the left and right sides at the same time.

[0155] When the second rotating door 422 opens the first inlet 231 connecting the centrifugal air duct and the air mixing duct 23, the first switch door opens the first air supply port 11 at the top, and the third air guide blade is in a shielding state, a part of the airflow of the centrifugal air duct is sent out from the first air supply port 11 at the top, and the other part of the airflow enters the air mixing duct 23 and mixes with the airflow of the crossflow duct, and is sent out together from the ventilation hole 71 at the second air supply port 12. At this time, the wind sent out from the ventilation hole 71 at the second air supply port 12 has a smaller wind feeling. The first air supply port 11 at the top has a smaller wind feeling due to its higher height, and the air outlet of the first air supply port 11 can increase the overall air outlet volume, and the air conditioner 100 can present a large cooling capacity and low wind feeling air supply effect (for example Figure 2 shown).
