[0044] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0045] The air conditioner 100 according to an embodiment of the present invention will be described below with reference to the accompanying drawings.

[0046] like Figure 1 As shown, the air conditioner 100 according to the embodiment of the present invention includes a housing 1 , a first heat exchanger 2 and a first fan assembly 3 .

[0047] Specifically, refer to Figure 1 The housing 1 limits a first air duct 11, and the housing 1 has an air inlet 12, a first air outlet 13, and a second air outlet 14 connected to the first air duct 11. The air inlet 12 and the first air outlet 13 are located on the side wall of the housing 1, and the second air outlet 14 is located on the top wall of the housing 1. The first heat exchanger 2 is arranged in the first air duct 11, and the first heat exchanger 2 is spaced apart from the air inlet 12 to define an air flow channel 111. The first fan assembly 3 is arranged in the first air duct 11, and the first fan assembly 3 is located between the first heat exchanger 2 and the first air outlet 13.

[0048] It can be understood that the first air duct 11 can be used to support the first heat exchanger 2 and the first fan assembly 3. The first heat exchanger 2 can exchange heat with the airflow to cool or heat the airflow. The first fan assembly 3 can drive at least part of the airflow from the air inlet 12 to the first air outlet 13, and can also drive at least part of the airflow from the first air outlet 13 to the second air outlet 14. If the first fan assembly 3 rotates forward to drive at least part of the airflow from the air inlet 12 to the first air outlet 13, then the first fan assembly 3 rotates reversely to drive at least part of the airflow from the first air outlet 13 to the second air outlet 14; if the first fan assembly 3 rotates reversely to drive at least part of the airflow from the air inlet 12 to the first air outlet 13, then the first fan assembly 3 rotates forward to drive at least part of the airflow from the first air outlet 13 to the second air outlet 14.

[0049] The air conditioner 100 of the present invention has two modes: wind sense and no wind sense. When the air conditioner 100 is in the wind sense mode, at least part of the airflow flows into the first air duct 11 from the air inlet 12, exchanges heat with the first heat exchanger 2, and then blows out of the air conditioner 100 from the first air outlet 13, thereby achieving cooling or heating of the user's activity area. Since the first air outlet 13 is located on the side wall of the housing 1, the user can feel the airflow after the airflow is blown out from the first air outlet 13.

[0050] When the air conditioner 100 is in the windless mode, the air flows from the first air outlet 13 into the first air duct 11, and after heat exchange with the first heat exchanger 2, at least part of the air flows to the second air outlet 14 through the air flow channel 111, and blows out of the air conditioner 100 from the second air outlet 14, thereby also cooling or heating up the user's activity area. Since the second air outlet 14 is located on the top wall of the housing 1, the user can hardly feel the air flow after the air flow is blown out from the second air outlet 14. The air conditioner 100 with the windless mode can improve the user's comfort in using the air conditioner 100, which is beneficial to the user's health.

[0051] In the related art, the air outlets of cabinet air conditioners are mostly arranged on the side walls of the shell. After the air conditioner is turned on, the air flows out from the air outlet, and it is difficult to avoid the cold air or hot air blowing directly to the user, resulting in a poor user experience. Moreover, being directly blown by the cold air or hot air from the air conditioner for a long time also has certain harm to physical health.

[0052] The air conditioner 100 according to the embodiment of the present invention has a second air outlet 14 on the top wall of the shell 1, so that the air flow can enter the first air duct 11 from the first air outlet 13. After exchanging heat with the first heat exchanger 2, at least part of the air flow can flow to the second air outlet 14 through the air flow channel 111, and be blown out of the air conditioner 100 from the second air outlet 14. Since the second air outlet 14 is located on the top wall of the shell 1, the air flow will not be blown directly to the user, which can give the user a good experience of no wind feeling, and thus is beneficial to the user's health.

[0053] In some embodiments of the present invention, the air conditioner 100 further includes a first switch door 4, which is movably disposed on the housing 1 to open or close the air inlet 12. It is understood that the first switch door 4 may be a sliding door, which is movably disposed at the air inlet 12 to open and close the air inlet 12; the first switch door 4 may also be a Figure 1-Figure 4 The revolving door shown in the figure comprises a plurality of windshield plates 41, which are arranged spaced apart along the width direction of the air inlet 12, and the plurality of windshield plates 41 are arranged in the up and down directions of the housing 1 (such as Figure 3 The first switch door 4 can be rotated in the up and down direction (as shown) to open and close the air inlet 12. The first switch door 4 can also be a door body in other forms that can open or close the air inlet 12, and no excessive restrictions are made here.

[0054] When the air conditioner 100 is in the wind sensing mode, the air inlet 12 can be opened, and the air flow flows from the air inlet 12 to the first air outlet 13; when the air conditioner 100 is in the windless mode, the air inlet 12 can be closed, and the first switch door 4 and the first heat exchanger 2 define an air flow channel 111, and the air flow flows from the first air outlet 13, through the air flow channel 111, to the second air outlet 14.

[0055] Combination Figure 4-Figure 5 According to some embodiments of the present invention, the air conditioner 100 further includes a first filter 5, which is disposed at the air inlet 12. When the first switch door 4 closes the air inlet 12, the first filter 5 is located at a side of the first switch door 4 away from the first heat exchanger 2. It can be understood that when the air conditioner 100 is in the wind sensing mode, the airflow enters the first air duct 11 from the air inlet 12, and the first filter 5 disposed at the air inlet 12 can filter dust or harmful substances mixed in the airflow, so that the airflow entering the first air duct 11 is clean and harmless, thereby protecting the components in the first air duct 11 from damage, and also making the airflow blowing out of the air conditioner 100 clean and harmless, which is beneficial to the health of the user.

[0056] In the windless mode, the first switch door 4 closes the air inlet 12, and the first filter 5 is located on the side of the first switch door 4 away from the first heat exchanger 2, that is, the first filter 5 is located on the outside of the airflow channel 111. When the airflow passes through the airflow channel 111, it will not blow toward the first filter 5. Therefore, the dust and harmful substances on the first filter 5 will not be carried by the airflow from the airflow channel 111 to the second air outlet 14 and blown toward the user activity area, which is beneficial to the health of the user.

[0057] Further, in Figure 4In the example shown, the air conditioner 100 further includes a mounting plate 90, and the first filter 5 is connected to the mounting plate 90. The first filter 5 and the mounting plate 90 can be formed separately, or the first filter 5 and the mounting plate 90 can be formed integrally. The first switch door 4 is a rotating door, and the rotating door includes a plurality of windshield plates 41, and the plurality of windshield plates 41 are arranged in a spaced relationship along the circumferential direction of the air inlet 12, and the plurality of windshield plates 41 are arranged in the upper and lower directions of the housing 1 (such as Figure 3 The first filter screen 5 and the first switch door 4 can be rotatably mounted on the mounting plate 90 (in the up and down directions shown in the figure). The mounting plate 90 can provide support for the first filter screen 5 and the first switch door 4. The mounting plate 90 can also facilitate the installation of the first filter screen 5 and the first switch door 4 on the housing 1.

[0058] In some embodiments of the present invention, reference Figure 1-Figure 2 and Figure 5 The air conditioner 100 further includes a second fan assembly 6, which is disposed in the first air duct 11. The first air duct 11 can provide support for the second fan assembly 6. The second fan assembly 6 is located in the air flow channel 111 or opposite to the air flow channel 111 to drive the air flow to the second air outlet 14. It can be understood that the second fan assembly 6 can make the air flow flow to the second air outlet 14 more smoothly, thereby facilitating the realization of the windless mode of the air conditioner 100.

[0059] It should be noted that, in one example, when the second fan is working, the air inlet 12 can be closed. At this time, the first fan assembly 3 drives the airflow from the first air outlet 13 into the first air duct 11, and the second fan assembly 6 drives the airflow to flow out from the second air outlet 14; in another example, when the second fan is working, the air inlet 12 can also be opened. At this time, the rotation speed of the second fan assembly 6 can be designed according to actual conditions, so that the airflow can enter the first air duct 11 from the air inlet 12 and the first air outlet 13 at the same time, and the second fan assembly 6 can drive the airflow to flow out from the second air outlet 14.

[0060] Combination Figure 5 In some embodiments of the present invention, the second fan assembly 6 is disposed adjacent to the second air outlet 14, thereby facilitating driving at least part of the airflow to flow out of the second air outlet 14. Further, as Figure 2 As shown, the second fan assembly 6 includes a second wind wheel 61, and the second wind wheel 61 can be an axial flow wind wheel, and the axis of the second wind wheel 61 is inclined to the front side in the direction from bottom to top. It can be understood that the second wind wheel 61 can drive at least part of the airflow to flow to the second air outlet 14. The axial flow wind wheel has the characteristics of simple structure, stability and reliability, low noise, and good exhaust effect. The use of the axial flow wind wheel can better drive the airflow to flow to the second air outlet 14. The axis of the second wind wheel 61 is inclined to the front side in the direction from bottom to top (such as Figure 5Tilting forward in the up and down directions (as shown) can direct the airflow more toward the user activity area, and can more efficiently cool or heat the user activity area without the airflow blowing directly on the user.

[0061] Furthermore, if Figure 2 As shown, the second fan assembly 6 also includes a second motor 62 and a second motor cover 63. The second motor 62 can drive the second wind wheel 61 to rotate. The rotation of the second wind wheel 61 can drive the airflow to the second air outlet 14. The second motor cover 63 can support the second motor 62, thereby facilitating the installation and fixation of the second motor 62.

[0062] Furthermore, if Figure 2 As shown, the air conditioner 100 further includes a mounting frame 60 and a second air guide ring 70. Figure 6 The second air guide ring 70 is provided with an air guide grille 402, and the second motor cover 63 can fix the second motor 62 and the second wind wheel 61 on the second air guide ring 70. The second air guide ring 70 is connected to the mounting frame 60, and the mounting frame 60 is connected to the shell 1 to fix the second motor 62, the second wind wheel 61 and the second air guide ring 70 on the shell 1. The second air guide ring 70 surrounds the wind wheel, which can increase the air volume of the wind wheel and guide more airflow out of the second air outlet 14. The air guide grille 402 can disperse the airflow, so that the air outlet of the second air outlet 14 is more uniform.

[0063] According to some embodiments of the present invention, Figure 1 and Figure 5 As shown, the air conditioner 100 further includes a second filter 7, which is movably disposed at the first air outlet 13 to open or block the first air outlet 13. It can be understood that when the air conditioner 100 is in the wind sensing mode, at least part of the airflow enters the first air duct 11 from the air inlet 12 and flows out from the first air outlet 13. At this time, the second filter 7 opens the first air outlet 13 so that the airflow can flow out from the first air outlet 13 smoothly.

[0064] In the windless mode, the air flows from the first air outlet 13 to the first air duct 11, and at least part of the air flows out from the second air outlet 14. The second filter 7 blocks the first air outlet 13 to filter out dust or harmful substances mixed in the air flow, so that the air flow entering the first air duct 11 is clean and harmless, thereby protecting the components in the first air duct 11 from damage, and also making the air flow blown out of the air conditioner 100 clean and harmless, which is beneficial to the health of the user.

[0065] refer to Figure 7In some embodiments of the present invention, the air conditioner 100 further includes a driving assembly 8 for driving the second filter 7 to move, and the driving assembly 8 includes a first reel 81, a second reel 82, a first drive motor 83, a second drive motor 84, and a winding rope. Specifically, the first reel 81 and the second reel 82 are respectively located on opposite sides of the first air outlet 13, the first drive motor 83 is connected to the first reel 81, the second drive motor 84 is connected to the second reel 82, one end of the winding rope is connected to the first reel 81, the other end of the reel is connected to one end of the second filter 7, and the other end of the second filter 7 is connected to the second reel 82.

[0066] Among them, the first driving motor 83 can drive the first reel 81 to rotate, and the rotation of the first reel 81 can drive the winding rope to wind towards the first reel 81, and the winding rope drives the second filter 7 to move toward the first reel 81. When the second filter 7 moves to the first reel 81, the second filter 7 can block the first air outlet 13.

[0067] Furthermore, if Figure 7 As shown, the air conditioner 100 also includes a guide rail 80 for supporting the movement of the second filter 7. The guide rail 80 is arranged at intervals at both ends of the first reel 81 and the second reel 82. The opposite ends of the second filter 7 are located in the guide rail 80. The setting of the guide rail 80 can facilitate the movement of the second filter 7.

[0068] According to some embodiments of the present invention, Figure 1 As shown, the first heat exchanger 2 is in a zigzag shape and extends along the height direction of the housing 1. It is understandable that the zigzag first heat exchanger 2 can increase the heat exchange area, making the heat exchange efficiency higher, so that the cooling or heating effect of the air conditioner 100 can be better.

[0069] refer to Figure 1-Figure 2 In some embodiments of the present invention, the first fan assembly 3 includes a first wind wheel 31, and the first wind wheel 31 can be an axial flow wind wheel. In the wind-sensing mode, the first wind wheel 31 can drive at least part of the airflow from the air inlet 12 to the first air outlet 13; in the no-wind-sensing mode, the first wind wheel 31 can drive at least part of the airflow from the first air outlet 13 to the second air outlet 14. The axial flow wind wheel has the characteristics of simple structure, stability and reliability, low noise, and good exhaust effect. Using an axial flow wind wheel as the first wind wheel 31 can better drive the airflow to the first air outlet 13 or the second air outlet 14.

[0070] Furthermore, if Figure 2 and Figure 5As shown, the first fan assembly 3 also includes a first motor 32 and a first motor cover 33. The first motor 32 can drive the first wind wheel 31 to rotate. The rotation of the first wind wheel 31 can drive the airflow to the first air outlet 13 or the second air outlet 14. The first motor cover 33 can support the first motor 32, thereby facilitating the installation and fixation of the first motor 32.

[0071] According to some embodiments of the present invention, Figure 1-Figure 2 and Figure 5 The first fan assembly 3 is along the length direction of the first air outlet 13 (such as Figure 5 Thus, in the wind-sensing mode, at least part of the airflow can be driven more efficiently from the air inlet 12 to the first air outlet 13, increasing the air volume of the first air outlet 13, so that the cooling or heating effect of the air conditioner 100 is better; in the wind-free mode, at least part of the airflow can be driven more efficiently from the first air outlet 13 to the second air outlet 14, increasing the air volume of the second air outlet 14, and also making the cooling or heating effect of the wind-free mode of the air conditioner 100 better.

[0072] In such Figure 2 and Figure 5 In the example shown, the air conditioner 100 further includes an air outlet frame 40, which has a longitudinal direction (eg, Figure 5 The plurality of mounting openings 401 are spaced apart in the vertical direction (shown in FIG. 1 ), and the plurality of first fan assemblies 3 are mounted in the plurality of mounting openings 401 in a one-to-one correspondence. The mounting openings 401 can support the first fan assemblies 3 and provide an installation environment for the first fan assemblies 3. Further, referring to Figure 8 An air guide grille 402 may be provided at each installation opening 401 , and the air guide grille 402 may disperse the airflow, so that the airflow blown out from the first air outlet 13 is more uniform, thereby improving the user's comfort.

[0073] In such Figure 2 and Figure 5 In the example shown, the air conditioner 100 further includes an air guide plate 50, which is connected to the air outlet frame 40. The air guide plate 50 has a longitudinal direction (eg, Figure 5 There are multiple first air guide rings 501 spaced apart in the upper and lower directions (as shown in the figure), the multiple first air guide rings 501 correspond one by one to the multiple first fan assemblies 3, and each first air guide ring 501 surrounds a first fan assembly 3, thereby increasing the air output of the first fan assembly 3.

[0074] In such Figure 2 and Figure 5In the example shown, the air conditioner 100 also includes a bracket 30, and the first heat exchanger 2, the air outlet frame 40 and the air guide ring plate body 50 are all installed on the bracket 30. The bracket 30 installs the first heat exchanger 2, the air outlet frame 40 and the air guide ring plate body 50 together on the shell 1, thereby facilitating the utilization of the spatial structure of the air conditioner 100, making the structure of the air conditioner 100 more compact.

[0075] In some embodiments of the present invention, Fig. 9 The air conditioner 100 further includes a second switch door 9, which is movably disposed on the housing 1 to open or close the second air outlet 14. When the air conditioner 100 is in a wind-sensing mode, the second air outlet 14 can be closed by the second switch door 9. When the air conditioner 100 is in a no-wind-sensing mode, the second switch door 9 opens the air outlet so that air can flow out of the air conditioner 100 from the second air outlet 14. The second switch door 9 closes the second air outlet 14 to protect the internal components of the housing 1 and prevent dust and other debris from entering the housing 1.

[0076] According to some embodiments of the present invention, the air conditioner 100 further includes a second heat exchanger 10, which is disposed in the first air duct 11. The second heat exchanger 10 is adjacent to the air inlet 12 relative to the first heat exchanger 2, and the first heat exchanger 2 and the second heat exchanger 10 are spaced apart to define an air flow channel 111. Fig.10 In the example shown, in the wind sensing mode, at least part of the airflow flows from the air inlet 12 to the first air outlet 13, and the first heat exchanger 2 and the second heat exchanger 10 are located in the flow direction of the airflow. The airflow can perform heat exchange twice through the first heat exchanger 2 and the second heat exchanger 10, thereby achieving a better heat exchange effect and improving the cooling or heating effect of the air conditioner 100.

[0077] In such Fig.10 In the example shown, in the windless mode, the rotation speeds of the first fan assembly 3 and the second fan assembly 6 can be designed as needed, so that the first fan assembly 3 and the second fan assembly 6 can cooperate to drive the airflow to enter the first air duct 11 from the air inlet 12 and the first air outlet 13 at the same time, and the airflow entering from the air inlet 12 enters the airflow channel 111 after heat exchange with the second heat exchanger 10, and the airflow entering from the first air outlet 13 enters the airflow channel 111 after heat exchange with the first heat exchanger 2, and the merged airflow flows out from the second air outlet 14. Therefore, the air intake from the air inlet 12 and the first air outlet 13 at the same time can increase the air volume of the air conditioner 100, and the simultaneous operation of the first heat exchanger 2 and the second heat exchanger 10 can increase the heat exchange efficiency and enhance the heat exchange effect.

[0078] In some embodiments of the present invention, the air conditioner 100 further includes a fresh air module 20, which can perform indoor air exchange, introduce outdoor fresh air into the room, and export indoor air to the outside.
