Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0038] Figure 1 This is a schematic structural diagram of an air conditioner indoor unit according to an embodiment of the present invention, as shown below. Figure 1 As shown, and refer to Figures 2 to 9 This invention provides an indoor air conditioning unit, including a housing 110. The housing 110 has at least three air outlets 111. Each air outlet 111 extends vertically, and the multiple air outlets 111 are sequentially arranged along the circumferential direction of the housing 110. The angle between any two adjacent air outlets 111 is less than or equal to 130°.

[0039] In this embodiment, the indoor unit of the air conditioner is in operation, and the airflow inside the casing 110 flows out of the casing 110 through the air outlet 111. Multiple air outlets 111 can deliver air simultaneously, achieving 360° air delivery to the space. This solves the problems of single air delivery direction and limited air delivery range in the prior art, and meets people's requirements for air delivery comfort.

[0040] In some embodiments of the present invention, the indoor unit of the air conditioner further includes a plurality of air supply devices 300, the number of air supply devices 300 being the same as the number of air outlets 111, and each air supply device 300 being configured to correspond to one air outlet 111.

[0041] In this embodiment, when the indoor unit of the air conditioner is turned on, multiple air supply devices 300 are activated simultaneously, so that the airflow inside the housing 110 flows out of the housing 110 through the corresponding air outlet 111. The flow rate and wind speed are controllable.

[0042] Of course, multiple air supply devices 300 can also work at different times, that is, some air supply devices 300 can stop working, and the air outlet 111 corresponding to the closed air supply device 300 has the function of air intake.

[0043] Specifically, some air supply devices 300 are closed, while the remaining air supply devices 300 are open. The air outlets 111 corresponding to the open air supply devices 300 transmit the airflow inside the housing 110 to the outside, creating a negative pressure inside the housing 110. At this time, the air outlets 111 corresponding to the closed air supply devices 300 can act as air intake channels, introducing airflow from outside the housing 110 into the housing 110. This increases the air intake volume inside the housing 110, thereby increasing the air output volume of the open air outlets 111 of the corresponding air supply devices 300.

[0044] In some embodiments of the present invention, a damper or other sealing device may be provided at each air outlet 111, and when the air supply device 300 stops working, the corresponding air outlet 111 may be closed by the sealing device.

[0045] In some embodiments of the present invention, a heat exchanger 400 is provided inside the housing 110 so that the airflow flowing out through the air outlet 111 is the heat exchange airflow.

[0046] In this embodiment, a heat exchanger 400 is installed inside the housing 110. Depending on the ambient temperature and user needs, the heat exchanger 400 can cool or heat. The heat exchange air flows out of the housing 110 through the air outlet 111, providing the user with the cold or hot air they need to meet their needs.

[0047] In some embodiments of the present invention, the heat exchanger 400 extends in a vertical direction and the length of the heat exchanger 400 is greater than the length of the air outlet 111.

[0048] In this embodiment, the length of the heat exchanger 400 is designed to ensure more efficient heat exchange after the external airflow enters the housing 110.

[0049] In some embodiments of the present invention, the length of the heat exchanger 400 is less than the length of the air outlet 111, which may cause some airflow to flow out through the air outlet 111 without heat exchange. That is, the airflow flowing out through the air outlet 111 is a mixture of heat-exchanged air and non-heat-exchanged air, which makes the user feel more comfortable.

[0050] In some embodiments of the present invention, the heat exchanger 400 includes an air inlet space 410 extending in a vertical direction and a heat exchange portion 420 surrounding the air inlet space 410. An air supply device 300 is disposed on the side of the heat exchange portion 420 opposite to the air inlet space 410.

[0051] In this embodiment, external airflow flows into the air inlet space 410 enclosed by the heat exchange section 420, exchanges heat with the heat exchange section 420, and then flows out through the air outlet 111 under the drive of the air supply device 300. This can reduce air supply resistance and improve heat exchange efficiency.

[0052] In some embodiments of the present invention, the air supply device 300 is located between the heat exchange section 420 and the air outlet 111.

[0053] In some embodiments of the present invention, the housing 110 further includes an air inlet communicating with the air inlet space 410. The air inlet is located at the top of the housing 110. Of course, in some embodiments, the air inlet may also be located at the bottom of the housing 110. In some embodiments, the air inlet may also be located at both the top and bottom of the housing 110.

[0054] In the above embodiment, the air inlet is located at the top of the housing 110, which is beneficial for the upper hot air to enter the interior of the housing 110 through the air inlet in the cooling mode and exchange heat with the heat exchanger 400, thereby improving the cooling effect.

[0055] Of course, the air inlet is located at the bottom of the housing 110, which is beneficial for the cold air at the bottom of the environment to enter the interior of the housing 110 through the air inlet in the heating mode and exchange heat with the heat exchanger 400, thereby improving the heating effect.

[0056] In some embodiments of the present invention, the air inlet and the air inlet space 410 are coaxially arranged. In this embodiment, the air inlet and the air inlet space 410 enclosed by the heat exchanger 400 are coaxially arranged, which facilitates the flow of external airflow into the air inlet space 410 through the air inlet.

[0057] In some embodiments of the present invention, the outer peripheral surface of the heat exchanger 400 is provided with a plurality of grooves 422 extending in the vertical direction, and each groove 422 is provided corresponding to an air outlet 111.

[0058] In this embodiment, the groove 422 and the air outlet 111 together form a receiving space. Alternatively, the two grooves 422 of the heat exchanger 400 can be separated by a protrusion 421, which can be used for the installation of the heat exchanger 400.

[0059] In some embodiments of the present invention, the air supply device 300 is partially disposed within the groove 422.

[0060] In this embodiment, the air supply device 300 is disposed within the receiving space formed by the groove 422 and the air outlet 111. Part of the air supply device 300 is within the groove 422, with the portion protruding from the groove 422 facing the corresponding air outlet 111. This makes the overall indoor unit of the air conditioner more compact.

[0061] In some embodiments of the present invention, the air supply device 300 is a vertically arranged cross-flow fan.

[0062] In this embodiment, the air supply device 300 is selected with a cross-flow fan whose axial length is not limited, which can increase the air supply distance, avoid turbulence, and make the heat exchange air flowing out of the air outlet 111 uniform, resulting in a better user experience.

[0063] In some embodiments of the present invention, the length of the groove 422 is less than the length of the heat exchanger 400. For example, the groove 422 extends through the lower surface of the heat exchanger 400 but does not extend through the upper surface of the heat exchanger 400. Alternatively, the groove 422 extends through the upper surface of the heat exchanger 400 but does not extend through the lower surface of the heat exchanger 400. Alternatively, the groove 422 does not extend through the lower surface of the heat exchanger 400 and does not extend through the upper surface of the heat exchanger 400. Of course, in some embodiments of the present invention, the length of the groove 422 is equal to the length of the heat exchanger 400, that is, the groove 422 may also extend through both the upper and lower surfaces of the heat exchanger 400.

[0064] In some embodiments of the present invention, the impeller of the cross-flow fan and the air inlet of the air duct are located in the groove 422, and the air outlet of the cross-flow fan is connected to the edge of the air outlet 111.

[0065] In other words, each air outlet 111 and its corresponding groove 422 has a duct body that defines the air outlet. For example, the duct body can be the volute and volute tongue of a cross-flow fan.

[0066] In some embodiments of the present invention, each air outlet 111 and its corresponding recess 422 is provided with a duct body defining an air outlet. Multiple duct bodies are spaced apart, and the air supply device 300 is located within the ducts. A protrusion 421 between two recesses 422 of the heat exchanger 400 is inserted into the gap between two adjacent duct bodies. This optimized arrangement results in a more compact structure.

[0067] In some embodiments of the present invention, the air duct body includes a vertically arranged first air duct wall 113 and a second air duct wall 112. The end of the first air duct wall 113 away from the air outlet 111 is inserted into the groove 422. The end of the second air duct wall 112 away from the air outlet 111 contacts the end of the protrusion 421 near the air outlet 111.

[0068] In this embodiment, the first air duct wall 113 and the second air duct wall 112 are configured such that the first air duct wall 113 functions as a volute and the second air duct wall 112 functions as a volute tongue, thus forming a volute structure in the air duct body. This increases the stability of air delivery.

[0069] Of course, in some embodiments of the present invention, the end of the first air duct wall 113 furthest from the air outlet 111 is inserted into the groove 422, and the end of the second air duct wall 112 furthest from the air outlet 111 is inserted into the groove 422, with the depth of the first air duct wall 113 inserted into the groove 422 being greater than the depth of the second air duct wall 112 inserted into the groove 422. This also ensures the stability of the air supply.

[0070] In some embodiments of the present invention, the indoor unit of the air conditioner further includes a filter device 200. The filter device 200 is disposed inside the housing 110 and has a first position and a second position. In the first position, the filter device 200 blocks the air outlet 111; in the second position, the filter device 200 does not block the air outlet 111.

[0071] In this embodiment, when the air supply device 300 is operating and the corresponding air outlet 111 delivers airflow from inside the housing 110 to the outside of the housing 110, the corresponding filter device 200 is in the second position, not obstructing the air outlet 111, allowing airflow from inside the housing 110 to flow out smoothly through the air outlet 111. When the air supply device 300 stops operating, the corresponding filter device 200 is in the first position, obstructing the air outlet 111 to prevent foreign objects from entering the housing 110. When the air supply device 300 stops operating and the corresponding air outlet 111 acts as an air inlet, delivering airflow from outside the housing 110 to the inside of the housing 110, the corresponding filter device 200 is in the first position, obstructing the air outlet 111.

[0072] In some embodiments of the present invention, the filter device 200 of the air conditioner indoor unit includes a support member 210 and a filter 220, with the support member 210 connected to the upper end of the filter 220. It also includes a counterweight 240, which is disposed at the lower end of the filter 220 to keep the filter 220 in an extended state under the weight of the counterweight 240.

[0073] In this embodiment, when the filter 220 is in the extended state, the weight of the counterweight 240 helps maintain its extended state, making it less susceptible to change due to external forces. The counterweight 240 further enhances the stability of its extended state.

[0074] In some embodiments of the present invention, the filter device 200 further includes a drive device 230 for driving the support member 210 to unwind or rewind the filter 220, so that the filter device 200 switches between a first position and a second position.

[0075] In this embodiment, the drive device 230 is activated, causing the support member 210 to rotate, which in turn causes the filter screen 220 to rotate, thereby realizing the winding or unwinding of the filter screen device 200. The drive device 230 makes the position switching operation of the filter screen device 200 simple.

[0076] In some embodiments of the present invention, the number of filter devices 200 is the same as the number of air outlets 111, so that each air outlet 111 can be in a blocked or open state. In some embodiments of the present invention, the blocking part of the filter device 200 is a filter.

[0077] In some embodiments of the present invention, the duct body extends from the two vertical edges of the air outlet 111 into the housing 110. The duct body and the housing 110 are integrally formed, which makes the duct structure simple, easy to manufacture, and compact, and is particularly suitable for air conditioners with multiple air outlets 111 around the circumference that can achieve circumferential air supply.

[0078] In some embodiments of the present invention, the housing 110 can be of various shapes, including but not limited to circular and elliptical. This arrangement makes the appearance of the housing 110 more streamlined.

[0079] In some embodiments of the present invention, the housing 110 is composed of a plurality of arc-shaped plates 114 connected in sequence, the plurality of arc-shaped plates 114 forming a petal shape. The housing 110 in this embodiment is more aesthetically pleasing.

[0080] Furthermore, in some embodiments of the present invention, the distance from the farthest point of each of the arc-shaped plates 114 to the axis center is equal, that is, the point of the farthest end of the petals formed by the arc-shaped plates 114 to the axis center lies on the circumference of a large circle. And the point closest to the axis center also lies on the circumference of a small circle. It should be noted that multiple arc-shaped plates 114 do not mean that each arc-shaped plate 114 must be manufactured separately and then assembled. The entire housing 110 can also be integrally formed, only appearing as if the arc-shaped plates 114 are assembled.

[0081] In some embodiments of the present invention, each of the arc-shaped plates 114 is provided with at least one air outlet 111. Of course, one air outlet 111 is preferred, and the air outlet 111 can be located at the furthest point from the axis on the arc-shaped plate. In this embodiment, the arrangement of multiple arc-shaped plates 114, compared to a single cylindrical shell 110, allows the airflow within the shell 110 to exit at a larger angle from the air outlet 111, which is more conducive to 360° full-coverage air supply.

[0082] In some embodiments of the present invention, each of the arc-shaped plates 114 is provided with a horizontally arranged support rod 115 at its upper end. The support rod is located on the upper rear side of the air outlet 111, and the support rod 115 is parallel to the plane where the air outlet 111 is located. In this embodiment, a filter device 200 can be installed on the support rod 115.

[0083] In some embodiments of the present invention, the housing structure 100 further includes a cover plate 130, which is disposed at one end of the housing 110 and has the aforementioned air inlet, so that external airflow enters the interior of the housing 110 through the air inlet.

[0084] In some embodiments of the present invention, a filter screen may be provided on the cover plate 130. In this embodiment, before the air enters the interior of the housing 110 through the air inlet, it needs to be filtered by the filter screen to block particulate impurities in the air and prevent them from entering the interior of the housing 110 and affecting the normal operation of the housing 110.

[0085] In some embodiments of the present invention, the top-view peripheral structure of the cover plate 130 may not be consistent with that of the housing 110. Of course, in some embodiments of the present invention, the top-view peripheral structure of the cover plate 130 may also be consistent with that of the housing 110. When the peripheral structure of the cover plate 130 is consistent with that of the housing 110, the connection is natural, reducing gaps.

[0086] In some embodiments of the present invention, the housing structure 100 further includes a mounting base 120, which is located at the other end of the housing 110 and connected to the housing 110.

[0087] The mounting position of the mounting base 120 depends on the mounting position of the cover plate 130, which are located at different ends of the housing 110. That is, when the cover plate 130 is located at the upper end of the housing 110, the mounting base 120 is located at the lower end of the housing 110; when the cover plate 130 is located at the lower end of the housing 110, the mounting base 120 is located at the upper end of the housing 110.

[0088] In this embodiment, the mounting base 120 can provide mounting support and / or accommodating space.

[0089] In some embodiments of the present invention, the mounting base 120 provides a receiving space. Specifically, the mounting base 120 is provided with a motor mounting cavity 121 corresponding to the cross-flow fan. In this embodiment, the mounting base 120 is provided with a motor mounting cavity 121 to accommodate the motor of the cross-flow fan.

[0090] In some embodiments of the present invention, the mounting base 120 is further provided with a plurality of heat exchanger mounting slots 122 located between each pair of adjacent motor mounting cavities 121. In this embodiment, there are multiple mounting slots 122, which together provide mounting space for the heat exchanger 400 to keep the heat exchanger 400 in a stable state. Specifically, the mounting base 120 includes two vertical clamping plates, a vertical support plate, and a horizontal support flange arranged at intervals. The vertical support plate is disposed between the two vertical clamping plates and connected to the two vertical clamping plates. The vertical support plate is perpendicular to the vertical clamping plates. The horizontal support flange is connected to the upper end of the vertical support plate so that the two vertical clamping plates and the horizontal support flange define the heat exchanger mounting slots 122.

[0091] In some embodiments of the present invention, the mounting base 120 is further provided with a control device mounting cavity 123. The mounting cavity provides mounting space for the control module, so that the control module is fixed within the mounting base 120. Further, the control device mounting cavity 123 is located in the middle of the mounting base 120.

[0092] In some embodiments of the present invention, the indoor unit of the air conditioner further includes a detection module, a memory, and a processor. Multiple detection modules are respectively disposed above each air outlet to detect whether a user is present within a preset range in front of the air outlet. The processor calculates the distance between the user's position and the air outlet. When the distance is greater than a first preset value and less than a second preset value, the speed of the air outlet is reduced according to the distance. When the distance is less than or equal to the first preset value, the air outlet stops emitting air. Simultaneously, one or more air outlets farthest from the current air outlet are accelerated. If acceleration of the one or more air outlets farthest from the current air outlet is permitted, each air outlet is accelerated. If partial acceleration is permitted, the partially permitted air outlets are accelerated. If all acceleration is not permitted, none are accelerated.

[0093] Therefore, those skilled in the art should recognize that although numerous exemplary embodiments of the present invention have been shown and described in detail herein, many other variations or modifications conforming to the principles of the present invention can be directly determined or derived from the disclosure of the present invention without departing from the spirit and scope of the invention. Thus, the scope of the present invention should be understood and construed as covering all such other variations or modifications.
