[0039] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the drawings, where the same or similar reference numerals represent the same or similar elements or elements with the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary and are only used to explain the present invention and should not be construed as a limitation of the present invention.

[0040] The following refers to Figures 1-12 , to describe the air conditioner indoor unit 100 according to the embodiments of the present invention.

[0041] An air conditioner indoor unit 100 according to an embodiment of the present invention includes a housing 10 and a switch door mechanism 20. The housing 10 is provided with an air outlet passage 101, an air outlet 102, and a diversion passage 103. The air outlet 102 communicates with the air outlet passage 101. The diversion passage 103 communicates with the outside of the housing 10 and the air outlet passage 101 for diverting the air flow in the air outlet passage 101 or for introducing the air flow in the air outlet passage 101. The switch door mechanism 20 is provided on the housing 10 for opening or closing the diversion passage 103.

[0042] In the above solution, the air outlet passage 101 is used to form an air outlet air flow, and the air outlet air flow is blown out through the air outlet 102. Therefore, the air outlet 102 can be located at the end of the air outlet passage 101 in the air outlet air flow. The diversion passage 103 can be located on one side of the air outlet direction of the air outlet air flow, so that the air in the external environment can be diverted into the air outlet passage 101 during the flow of the air outlet air flow and mixed with the air outlet air flow.

[0043] When cold air or hot air is present in the air outlet passage 101, the air outlet air flow passes through the diversion passage 103. At this time, a negative pressure is formed at the connection position between the air outlet passage 101 and the diversion passage 103, and the air in the external environment can enter the air outlet passage 101 along the diversion passage 103 and be mixed with the air outlet air flow. By this method, the air introduced from the external environment through the diversion passage 103 can adjust the temperature and humidity of the air outlet air flow in the air outlet passage 101, improve the comfort of the air outlet air flow, facilitate making the air outlet softer, reduce the probability of overly dry air outlet, and can enhance the air feeling.

[0044] When the pressure of the air flow in the air outlet channel 101 is relatively high, the diversion channel 103 can discharge air outward together with the air outlet 102. At this time, the diversion channel 103 can divide the air flow, playing a role in discharging air outward. It can be understood that the diversion channel 103 can increase the air outlet path of the air conditioner indoor unit 100, reduce the wind speed and wind pressure of the air outlet 102, avoid the situation of direct air outlet, improve the air feeling in front of the user, and achieve the effect of slow air outlet or no air feeling. Moreover, since the air outlet 102 is generally located in the front of the user, the air discharged from the diversion channel 103 can be sent in other directions, expanding the air outlet range, which is beneficial to quickly adjusting the temperature in the environment while enhancing the user's air feeling experience.

[0045] The door opening and closing mechanism 20 can refer to a door device that can be opened or closed. When the air conditioner indoor unit 100 is in the working state, the door opening and closing mechanism 20 opens the diversion channel 103. When the air conditioner indoor unit 100 is in the non-working state, the door opening and closing mechanism 20 can close the diversion channel 103, which can prevent external dust and other pollutants as well as organisms such as mosquitoes from entering the air outlet channel 101, effectively reducing the probability of the interior of the air conditioner indoor unit 100 being polluted due to the setting of the diversion channel 103, ensuring the cleanliness of the interior of the air outlet channel 101, and thus being beneficial to ensuring the healthy air outlet of the air conditioner indoor unit 100. Secondly, by closing the diversion channel 103 through the door opening and closing mechanism 20, the overall aesthetic appearance of the air conditioner indoor unit 100 can also be improved.

[0046] It should be noted that the air conditioner indoor unit 100 in the embodiment of the present invention can be, but is not limited to, a wall-mounted unit, a cabinet unit, a window unit, etc., and no specific limitation is made here.

[0047] According to the air conditioner indoor unit 100 in the embodiment of the present invention, by providing a diversion channel 103 communicating with the air outlet channel 101 through the casing 10, air can be introduced into the air outlet channel 101 to adjust the temperature and humidity of the air flow, making the air flow softer, and enhancing the comfort of the air flow and the user's air feeling. The diversion channel 103 can also be used for the air outlet channel 101 to discharge air outward, which is beneficial to reducing the direct blowing intensity of the air outlet 102, and can also make the air outlet more flexible and the air feeling better. That is to say, by setting the diversion channel 103, the user experience can be improved. By setting the door opening and closing mechanism 20, the diversion channel 103 can be closed when the air conditioner indoor unit 100 is not in use, preventing pollutants such as dust and mosquitoes from entering the diversion channel 103 and polluting the interior of the air outlet channel 101, keeping the interior of the air outlet channel 101 clean, thus maintaining long-term healthy air outlet and improving the overall aesthetic appearance of the air conditioner indoor unit 100.

[0048] In some embodiments of the present invention, such as Figure 1 、 Figure 3As shown, there are multiple drainage channels 103, and at least one of the multiple drainage channels 103 is the first channel 1031, and the first channel 1031 is provided on the bottom wall 104 of the housing 10; the switch door mechanism 20 includes a first door mechanism 21, and the first door mechanism 21 is used to open or close the first channel 1031.

[0049] The housing 10 can be provided with multiple drainage channels 103. Optionally, the drainage channels 103 can be provided on one or more of the top, bottom, left end, and right end of the housing 10. When the drainage channels 103 are provided in multiple, one or more than two of the multiple drainage channels 103 can be the first channel 1031, and the first channel 1031 is provided on the bottom wall 104 of the housing 10, so that air can be drawn into or discharged from the air outlet channel 101 from the bottom of the housing 10.

[0050] Among them, the switch door mechanism 20 should at least include a first door mechanism 21, and the first door mechanism 21 can open or close the first channel 1031. The first door mechanism 21 can refer to a door device that can achieve the opening or closing function.

[0051] It can be understood that when the air conditioner indoor unit 100 needs to be installed on the wall (for example, the air conditioner indoor unit 100 is a wall-mounted unit), the space below the housing 10 is relatively large and it is not easy to accumulate dust and other impurities. Therefore, setting the first channel 1031 on the bottom wall 104 of the housing 10 is beneficial to ensuring the cleanliness of the introduced air flow, enabling the air outlet flow to remain clean, which is beneficial to ensuring the health of users. Moreover, when the first channel 1031 exhausts air outward, the air outlet flow can blow downward, quickly adjusting the temperature in the surrounding environment and improving the air outlet effect.

[0052] Optionally, there can be multiple first channels 1031, and the multiple first channels 1031 are arranged at intervals along the length direction of the housing 10. The first door mechanism 21 is multiple and is arranged in one-to-one correspondence with the multiple first channels 1031. That is to say, the first channel 1031 can be multiple channels with smaller sizes, and air can be drawn into or discharged from the air outlet channel 101 through multiple channels. Among them, the length direction of the housing 10 can be, but is not limited to Figure 1 the left-right direction, and the cross-section of the first channel 1031 can be, but is not limited to, rectangular, circular, etc.

[0053] Optionally, the first channel 1031 can be one and extends along the length direction of the housing 10. As Figure 1 and Figure 4 shown, the first channel 1031 can be a strip-shaped long hole. Thus, the size of the first channel 1031 is relatively large, and the air intake or exhaust effect will be better. Moreover, this also facilitates the processing of the first channel 1031 on the housing 10, which is beneficial to reducing costs.

[0054] In some embodiments of the present invention, asFigures 3-7 As shown, the first door mechanism 21 includes a door body 211 and a driving component 212. The door body 211 closes the entrance of the first channel 1031; the driving component 212 drives the door body 211 to move in the vertical direction.

[0055] The door body 211 may refer to components such as a door panel. For example, a plate member having the same shape as the outlet of the first channel 1031.

[0056] The driving component 212 may be, but is not limited to, a cylinder, an electric push rod, or other driving components that output linear motion. Among them, the driving component 212 can drive the door body 211 to move downward to open the first channel 1031, and drive the door body 211 to move upward to close the first channel 1031. Alternatively, the driving component 212 can also drive the door body 211 to move upward to open the first channel 1031, and drive the door body 211 to move downward to close the first channel 1031.

[0057] By the way that the driving component 212 drives the door body 211 to move in the vertical direction to close or open the first channel 1031, the movement mode of the door body 211 is relatively simple, which is beneficial to improving the movement reliability of the door body 211, reducing the probability of failure, and extending the service life of the first door mechanism 21.

[0058] In some embodiments of the present utility model, as Figure 8 and Figure 9 shown, the driving component 212 includes: a base 2121, a rack 2122, a gear, and a rotary driving member 2123. The base 2121 is provided on the housing 10; the rack 2122 is connected to the door body 211; the gear meshes with the rack 2122; the rotary driving member 2123 is provided on the base 2121 and can drive the gear to rotate.

[0059] The base 2121 may refer to a component connected to the housing 10 and providing an installation position for the gear and the rotary driving member 2123. The base 2121 may be, but is not limited to, a plate structure or a box structure. Exemplarily, the base 2121 may be a box component, and the gear and the rotary driving member 2123 may be provided inside the box component. The rotary driving member 2123 may be, but is not limited to, a motor, a rotary cylinder, a rotary oil cylinder, etc.

[0060] In the above technical solution, the rotary driving member 2123 can drive the gear to rotate, so that the gear drives the rack 2122 to move up and down. Since the rack 2122 is connected to the door body 211, the door body 211 can be driven to move vertically to open or close the first channel 1031.

[0061] It can be understood that in the above embodiment, by setting the driving component 212 to include a base 2121, a rack 2122, a gear, and a rotary driving member 2123, the structure of the driving component 212 is simple and the reliability is relatively high, which is beneficial to improving the stability of the first door mechanism 21 and extending the service life of the entire mechanism.

[0062] In some embodiments of the present utility model, as Figure 11 shown, the base 2121 is provided with a guide groove 2121a extending in the vertical direction, the rack 2122 is inserted into the guide groove 2121a and is slidably engaged with the guide groove 2121a. In this technical solution, since the base 2121 is installed on the casing 10, the guide groove 2121a can limit the rack 2122, so that the casing 10 does not need to be provided with other matching structures for the rack 2122, which can simplify the installation structure of the rack 2122. Moreover, the guide groove 2121a can also guide the movement of the rack 2122, which can improve the movement reliability of the rack 2122.

[0063] In some embodiments of the present utility model, as Figures 1-7 and Figure 11 shown, the casing 10 includes a front frame 11 and a chassis 12. An air outlet channel 101, an air outlet 102, and a drainage channel 103 are formed on the front frame 11. The base 2121 is provided on the front frame 11, and the rear side of the front frame 11 is provided with an opening; the chassis 12 is provided in the opening.

[0064] Since the chassis 12 and the front frame 11 are assembled separately, and there are many components provided on the chassis 12, if the first door mechanism 21 is assembled to the chassis 12, the assembly difficulty is relatively high, which will affect the assembly efficiency. Therefore, by setting the base 2121 on the front frame 11, the first door mechanism 21 can be assembled to the front frame 11, which can reduce the assembly difficulty of the first door mechanism 21 and is beneficial to improving the assembly efficiency of the whole machine.

[0065] In some embodiments of the present utility model, as Figure 3 shown, the door body 211 has a first bottom surface 211a close to the outer side of the casing 10, and the bottom wall 104 has a second bottom surface 104a. Among them, the first bottom surface 211a and the second bottom surface 104a are flush; or, the first bottom surface 211a is located above the second bottom surface 104a; or, the first bottom surface 211a is located below the second bottom surface 104a.

[0066] It can be understood that when the door body 211 is in the state of closing the first channel 1031, the first bottom surface 211a can be flush with the second bottom surface 104a (see Figure 3), so that the bottom of the housing 10 is more regular, and the overall appearance is more beautiful, which can improve the service performance of the air conditioner indoor unit 100. In addition, when the door body 211 is in the state of closing the first channel 1031, the first bottom surface 211a can also be located on the upper side of the second bottom surface 104a, that is, the door body 211 is entirely located in the first channel 1031; alternatively, the first bottom surface 211a can also be located on the lower side of the second bottom surface 104a, that is, a part of the door body 211 protrudes relative to the bottom wall 104.

[0067] In some embodiments of the present invention, such as Figure 3 , Figure 5 and Figure 7 shown, the first channel 1031 includes a first part 10311 and a second part 10312. The first part 10311 is connected to the air outlet channel 101; the second part 10312 is located on the side of the first part 10311 away from the air outlet channel 101 and communicates the first part 10311 with the outside of the housing 10; wherein, the width directions of the first part 10311 and the second part 10312 are the same as the width direction of the housing 10, the width of the first part 10311 is smaller than the width of the second part 10312, and the width of the second part 10312 gradually decreases in the direction approaching the first part 10311.

[0068] For easy understanding, by way of example, the width directions of the first part 10311, the second part 10312 and the housing 10 can be Figure 3 the front-back direction.

[0069] In the above technical solution, since the width of the first part 10311 is smaller than the width of the second part 10312 and the width of the second part 10312 gradually decreases in the direction approaching the first part 10311, the second part 10312 is in a flared shape. When the first channel 1031 needs to draw air into the air outlet channel 101, the inlet side of the second part 10312 is larger, making it easier to introduce the air in the environment. And the width of the first part 10311 is smaller than the width of the second part 10312, so that the air flow pressure in the first part 10311 is greater than that in the second part 10312 and the air outlet channel 101, which can effectively prevent the air flow in the air outlet channel 101 from flowing back into the first part 10311, thus ensuring the air drawing effect.

[0070] In some embodiments of the present invention, such as Figure 7As shown, the air conditioner indoor unit 100 includes a panel 30. The panel 30 is configured to be movable relative to the housing 10 to open or close the air outlet 102. The panel 30 is provided with a first air-dispersing part 30a, and the first air-dispersing part 30a is used to disperse the air flowing through the panel 30; the air conditioner indoor unit 100 has a no-draft mode. When the air conditioner indoor unit 100 is in the no-draft mode, the panel 30 opens the air outlet 102, and at least a part of the first air-dispersing part 30a is located inside the air outlet 102. The air outlet passage 101 discharges air outward, and the first passage 1031 is configured to discharge air outward from the air outlet passage 101.

[0071] The first air-dispersing part 30a may refer to a structure for dispersing the air flow of the discharged air. The first air-dispersing part 30a may be, but is not limited to, air outlet holes, air outlet grilles, etc. Further, the air outlet holes and the air outlet grilles may be arranged in an array. Exemplarily, as Figures 1-7 shown, the first air-dispersing part 30a may be air outlet holes arranged in an array on the panel 30.

[0072] When the air conditioner indoor unit 100 is in the no-draft mode (see Figure 7 , the arrows in the figure indicate the flow direction of the discharged air flow), a part of the discharged air flow at the air outlet 102 is blocked by the panel 30, and under the action of the first air-dispersing part 30a, the discharged air flow is dispersed, which can effectively prevent the air from directly blowing on the user, making the discharged air softer, so as to bring a no-draft experience to the user. In this process, the pressure inside the air outlet passage 101 is relatively high, and a part of the discharged air flow will flow to the first passage 1031, which can reduce the air flow flowing to the air outlet 102. A part of the discharged air flow flows outwards from the first passage 1031. Therefore, the air discharge volume of the air conditioner indoor unit 100 can be increased, and the discharged air at the air outlet 102 can be further softened, further improving the no-draft air discharge of the air conditioner indoor unit 100.

[0073] Optionally, as Figures 3-7 shown, the air conditioner indoor unit 100 includes a wind deflector 40. The wind deflector 40 is arranged inside the air outlet 102 and is rotatable. The wind deflector 40 is provided with a second air-dispersing part 40a. In this embodiment, the structure of the second air-dispersing part 40a may be the same as the structure of the first air-dispersing part 30a. For example, as Figure 4 shown, the second air-dispersing part 40a is air outlet holes arranged in an array on the wind deflector 40.

[0074] It can be understood that when the air conditioner indoor unit 100 is in the no-draft mode (see Figure 7 ), a part of the discharged air flow can pass through the first air-dispersing part 30 of the panel 30 to disperse the air, and the other part can be blown to the other side under the guiding action of the wind deflector 40 and the discharged air flow is dispersed by the second air-dispersing part 40a. Thus, the air discharge range of the discharged air flow can be expanded, and the discharged air flow can be dispersed more evenly, further improving the softness of the discharged air, thereby further improving the no-draft effect.

[0075] In some embodiments of the present utility model, such as Figure 5 shown, the air conditioner indoor unit 100 has a cooling mode and a heating mode. When the air conditioner indoor unit 100 is in the cooling mode or the heating mode, the first channel 1031 is configured to introduce air into the air outlet channel 101.

[0076] In the above technical solution, when the air conditioner indoor unit 100 is in the cooling mode or the heating mode (see Figure 5 , the arrows in the figure indicate the flow direction of the air outlet airflow), the air outlet airflow quickly flows out from the air outlet channel 101 to the air outlet 102, and a negative pressure area is formed at the air outlet 102. At this time, the air in the external environment can be introduced into the air outlet channel 101 from the first channel 1031, so that the hot air in the external environment can be mixed with the air outlet airflow at the air outlet 102, thereby adjusting the temperature and humidity of the air outlet airflow at the air outlet 102, making the temperature of the air outlet airflow more comfortable and softer, and further improving the wind feeling.

[0077] In some embodiments of the present utility model, at least one of the plurality of drainage channels 103 is a second channel 1032, and the second channel 1032 is provided on the front wall 105 of the housing 10 (see Figure 7 ); the switch door mechanism 20 includes a second door mechanism, and the second door mechanism is used to open or close the second channel 1032.

[0078] In this embodiment, the structure of the second door mechanism may be the same as or different from that of the first door mechanism 21, which is not limited here.

[0079] It can be understood that there are at least two drainage channels 103, including the first channel 1031 and the second channel 1032. The air conditioner indoor unit 100 can introduce or exhaust air from the first channel 1031 and the second channel 1032, thereby increasing the air volume of air introduction or exhaust. When the air conditioner indoor unit 100 is in the heating mode or the cooling mode, the first channel 1031 and the second channel 1032 can increase the amount of mixed air and improve the mixing effect of the air outlet airflow, thereby further improving the temperature and humidity adjustment effect of the air outlet airflow. When the air conditioner indoor unit 100 is in the no-wind feeling mode, the first channel 1031 and the second channel 1032 can increase the exhaust air volume, further reducing the air volume and the air outlet speed at the air outlet 102, making the air outlet softer and further improving the no-wind feeling air outlet effect.

[0080] In some embodiments of the present utility model, such as Figure 7As shown, at least one of the plurality of air guiding channels 103 is the second channel 1032. The air conditioner indoor unit 100 further includes a panel 30 configured to be movable relative to the front wall 105 of the housing 10 between a first position and a second position. When the panel 30 is in the first position, it can cover the air outlet 102. When the panel 30 is in the second position, it can be away from the front wall 105, and a second channel 1032 is formed between the panel 30 and the front wall 105.

[0081] In this embodiment, there are at least two air guiding channels 103, including a first channel 1031 and a second channel 1032, so that air can be guided into or exhausted from the air outlet channel 101 through the first channel 1031 and the second channel 1032, thereby increasing the air volume of air guiding or exhausting.

[0082] When the panel 30 is in the first position, it can close the air outlet 102. When the panel 30 is in the second position, it can open the air outlet 102. At the same time, the panel 30 and the front wall 105 of the housing 10 can jointly form the second channel 1032, which can simplify the structure of the second channel 1032. In addition, when the panel 30 is in the first position, it can close the air outlet 102 and will not jointly form the second channel 1032 with the front wall 105 of the housing 10. This enables the panel 30 to act as a switch door for opening or closing the second channel 1032. Thus, when the air conditioner indoor unit 100 has both the first channel 1031 and the second channel 1032, the number of door mechanisms can be reduced, and further the number of components can be reduced, which is beneficial to cost reduction.

[0083] In some embodiments of the present invention, as Figure 12 shown, the air outlet channel 101 has a duct wall surface 1011. The air guiding channel 103 is communicated with the duct wall surface 1011 and forms a communication port 132. The communication port 132 has opposite first edge 132a and second edge 132b. The second edge 132b is arranged closer to the air outlet 102 than the first edge 132a. The second edge 132b is located on the side of the duct wall surface 1011 where the first edge 132a is located and away from the air outlet channel 101, or on the side of the extended surface of the duct wall surface 1011 away from the air outlet channel 101.

[0084] In the embodiments of the above solution, according to different design requirements of the air conditioner indoor unit 100, the duct wall surface 1011 of the air outlet channel 101 in the housing 10 can be set as but not limited to a plane or a curved surface, etc.

[0085] Refer to Figure 12, the first edge 132a and the second edge 132b can refer to the side lines of the communication port 132. The first edge 132a is away from the air outlet 102, and the second edge 132b is close to the air outlet 102. The casing 10 is designed according to requirements. Among them, the first edge 132a and the second edge 132b can be set to, but are not limited to, straight lines, curves, etc.

[0086] The communication port 132 can be arranged on the air outlet channel 101. That is to say, the first edge 132a and the second edge 132b can both be located on the air duct wall surface 1011, and the second edge 132b is located on the side of the air duct wall surface 1011 where the first edge 132a is located and away from the air outlet channel 101.

[0087] The communication port 132 can also be arranged at one end of the air outlet channel 101. That is to say, the first edge 132a is located on the air duct wall surface 1011, while the second edge 132b is located on the side of the extended surface 1012 of the air duct wall surface 1011 and away from the air outlet channel 101 (see Figure 12 ), where the "extended surface 1012 of the air duct wall surface 1011" can refer to the surface extended or stretched in the original trend on the basis of the air duct wall surface 1011, and the extended surface 1012 can be, but is not limited to, a plane, a curved surface, etc.

[0088] It can be understood that whether the second edge 132b is located on the side of the air duct wall surface 1011 where the first edge 132a is located and away from the air outlet channel 101, or on the side of the extended surface 1012 of the air duct wall surface 1011 and away from the air outlet channel 101, a height difference can be formed between the second edge 132b and the first edge 132a (see the height differences H1 and H2 in Figure 12 ). The position where the second edge 132b is located can reduce the obstruction to the air outlet airflow. When the air outlet airflow passes through the second edge 132b of the communication port 132, the airflow speed is faster and the airflow pressure is smaller, which can further increase the induced air negative pressure, so that the air in the external environment can be more easily introduced from the drainage channel 103 into the air outlet channel 101, improving the induced air effect and the air outlet feeling.

[0089] Optionally, the drainage channel 103 can be set to one or more. Referring to Figure 12 , the drainage channel 103 is two. There is a height difference H1 between the first edge 132a and the second edge 132b of the communication port 132 of one of the two drainage channels 103, and there is a height difference H2 between the first edge 132a and the second edge 132b of the communication port 132 of the other.

[0090] In the above technical solution, the wind speed in the air outlet passage 101 is generally relatively high. Since the housing 10 has a diversion passage 103, when the wind passes through the diversion passage 103, due to the relatively high wind speed, the pressure in the air outlet passage 101 is relatively small compared to the pressure in the diversion passage 103. Therefore, a negative pressure area is formed in the air outlet passage 101, and the air in the external environment can enter the air outlet passage 101 along the diversion passage 103, and after being mixed with hot air or cold air, it is blown out from the air outlet 102. In this solution, since a height difference can be formed between the second edge 132b and the first edge 132a of the communication port 132, the diversion passage 103 has a better air guiding effect, and the air introduced from the external environment can better adjust the temperature and humidity of the air at the air outlet 102, improve the comfort of the air outlet airflow, and is beneficial to achieving softer air outlet and better wind feeling.

For example, as Figure 3 、 Figure 5 and Figure 7 shown, the air conditioner indoor unit 100 may further include a wind wheel 50 and a heat exchanger 60. The wind wheel 50 is disposed in the air outlet passage 101, the housing 10 is further provided with an air inlet, and the heat exchanger 60 is disposed between the air inlet and the wind wheel 50. When the air conditioner indoor unit 100 operates, the wind wheel 50 can drive the air to enter the housing 10 from the air inlet, and perform heat exchange when passing through the heat exchanger 60 to achieve heating or cooling. At the same time, the wind wheel 50 can also drive the heated or cooled air outlet airflow to be discharged outward from the air outlet 102.
