[0039] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions from beginning to end. The embodiments described below with reference to the drawings are exemplary and are intended to explain the present invention, but should not be construed as limiting the present invention.

[0040] The following disclosure provides many different embodiments or examples for implementing different structures of the present invention. To simplify the disclosure of the present invention, the components and settings of specific examples are described below. Of course, they are only examples and are not intended to limit the present invention. In addition, the present invention may repeat reference numerals and / or letters in different examples. Such repetition is for the purpose of simplicity and clarity and does not itself indicate the relationship between the various embodiments and / or settings discussed. In addition, the present invention provides examples of various specific processes and materials, but those of ordinary skill in the art can recognize the applicability of other processes and / or the use of other materials.

[0041] Next, with reference to the accompanying drawings, an air conditioner 100 according to an embodiment of the present invention will be described.

[0042] As Figures 1-3 shown, the air conditioner 100 includes a housing 1, a blower wheel 2, and a heat exchange device 3.

[0043] As Figures 1-3 shown, the housing 1 is cylindrical, and the outer contour shape of the cross-section of the housing 1 can be formed into a circle, a polygon, or the like; an air inlet 10b is provided on the housing 1, and outside air can flow into the housing 1 through the air inlet 10b to achieve the air intake of the air conditioner. At least one air outlet 10a extending along the axial direction of the housing 1 is provided on the peripheral wall surface 12 of the housing 1, and the air inside the housing 1 can be discharged through the air outlet 10a to achieve the air outlet of the air conditioner 100; wherein, the air outlet 10a can be one or more, and when there are multiple air outlets 10a, the multiple air outlets 10a can be arranged at intervals along the circumferential direction of the housing 1.

[0044] It should be noted that the "cylindrical shape" in this application should be understood in a broad sense, and the "cylindrical shape" includes a cylindrical shape with a taper of 0 and a cylindrical shape with a non-zero taper; for example, when the taper of the cylindrical shape is 0, the structures and dimensions of the wall surfaces at both axial ends of the cylindrical shape are the same, and when the taper of the cylindrical shape is non-zero, the cylindrical shape can be a frustum shape, such as a frustum of a cone.

[0045] As Figure 2 and Figure 3 shown, the blower wheel 2 is provided inside the housing 1, and the blower wheel 2 is used to make the air flow enter the housing 1 from the air inlet 10b and blow out of the housing 1 from the air outlet 10a to drive the air flow.

[0046] As Figure 2 shown, the heat exchange device 3 is provided inside the housing 1, and the heat exchange device 3 is located on the air flow path 10e from the air inlet 10b to the air outlet 10a. The air flow path 10e is located inside the housing 1, and the air flow path 10e can be at least defined by the housing 1. Then, outside air flows into the housing 1 through the air inlet 10b, exchanges heat with the heat exchange device 3, and flows out from the air outlet 10a to achieve the adjustment of the indoor environmental temperature.

[0047] Among them, when the air conditioner 100 is in use, the axis 10 of the housing 1 extends vertically in the up and down direction or extends obliquely in the up and down direction. Since the air outlet 10a is formed on the peripheral wall of the housing 1 and the air outlet 10a extends along the axial direction of the housing 1, the air blown out by the air conditioner 100 can be blown out substantially along the radial direction of the housing 1, so that the air conditioner 100 blows out air on the peripheral wall surface 12 of the housing 1, avoiding the direct blowing of the air from the air conditioner 100 and facilitating the avoidance of excessive local air volume of the air conditioner 100, effectively improving the user's comfort and enhancing the user experience effect.

[0048] For the air conditioner 100 according to the embodiment of the present invention, by arranging the air outlet 10a on the peripheral wall surface 12 of the housing 1, the air conditioner 100 blows out air on the peripheral wall surface 12 of the housing 1, avoiding the direct blowing of the air from the air conditioner 100 and facilitating the avoidance of excessive local air volume of the air conditioner 100, effectively enhancing the user experience effect.

[0049] Optionally, the length of the air outlet 10a in the axial direction of the housing 1 can be greater than the length of the air outlet 10a in the circumferential direction of the housing 1, which is beneficial to saving the occupied space of the air conditioner 100 when the air conditioner 100 is in use.

[0050] In some embodiments, as Figure 2 shown, the heat exchange device 3 is arranged downstream of the wind wheel 2 to be located between the outer periphery of the wind wheel 2 and the housing 1. Then the heat exchange device 3 can be arranged at intervals between the wind wheel 2 and the housing 1. The air flow flowing into the housing 1 through the air inlet 10b first flows through the wind wheel 2 and then through the heat exchange device 3, so that the heat exchange device 3 has sufficient layout space, and the structural size of the heat exchange device 3 can be appropriately increased, thereby increasing the heat exchange area of the heat exchange device 3 and improving the heat exchange efficiency of the air conditioner 100 to ensure the refrigeration / heating efficiency of the air conditioner 100.

[0051] In some embodiments, as Figure 2 and Figures 4-7 shown, the heat exchange device 3 includes at least one sub-heat exchanger 31 arranged around the wind wheel 2 along an arc. Then the cross-sectional shape of the sub-heat exchanger 31 can be formed into an arc (such as an elliptical arc or a circular arc), which is convenient for simplifying the processing process of the sub-heat exchanger 31. At the same time, the heat exchange device 3 can be well matched with the structure of the housing 1 to ensure that the heat exchange device 3 has sufficient heat exchange area.

[0052] It should be noted that the sub-heat exchanger 31 being "arranged around" the wind wheel 2 can include the following situations: 1. The sub-heat exchanger 31 is arranged around the wind wheel 2 for a full circle; 2. The sub-heat exchanger 31 is arranged around the wind wheel 2 for less than a full circle. For example, the cross-sectional shape of the sub-heat exchanger 31 can be formed into a major arc or a minor arc. Of course, the sub-heat exchanger 31 can also be arranged around the wind wheel 2 for a half circle.

[0053] It can be understood that the sub-heat exchanger 31 can be one or more. When there are multiple sub-heat exchangers 31, the multiple sub-heat exchangers 31 can be arranged in sequence along the circumferential direction of the housing 1.

[0054] Of course, the sub-heat exchanger 31 can also extend along a non-arc line. For example, the heat exchange device 3 can also be configured to include multiple sub-heat exchangers 31 that extend along a straight line, and the multiple sub-heat exchangers 31 are arranged in sequence along the circumferential direction of the housing 1 to surround the wind wheel 2.

[0055] Optionally, in the example of Figure 2 , the sub-heat exchanger 31 is a microchannel heat exchanger, which is convenient for ensuring the energy efficiency of the heat exchange device 3 to better adapt to the energy efficiency upgrade of the air conditioner 100. Of course, the sub-heat exchanger 31 can also be formed into other types of heat exchangers, and is not limited thereto.

[0056] In some alternative embodiments, as shown in Figure 2 and Figure 4 , if the heat exchange device 3 only includes one sub-heat exchanger 31, it is beneficial to simplify the structure of the heat exchange device 3. And since the number of sub-heat exchangers 31 is small, it is convenient to improve the processing efficiency of the heat exchange device 3 without considering the cooperation between multiple sub-heat exchangers 31, which is beneficial to improving the assembly efficiency of the air conditioner 100. Among them, the sub-heat exchanger 31 surrounds the wind wheel 2 for more than half a week. At this time, the sub-heat exchanger 31 can be formed into an open ring (i.e., a non-closed ring), and the cross-sectional shape of the sub-heat exchanger 31 can be formed into a superior arc shape, which is convenient for ensuring the heat exchange area of the heat exchange device 3, thereby ensuring the heat exchange efficiency of the heat exchange device 3. Further ensure the cooling / heating efficiency of the air conditioner 100.

[0057] In a further embodiment of the present invention, as shown in Figure 4, the heat exchange device 3 further includes a wind deflector 32, and the wind deflector 32 is arranged around the wind wheel 2 along an arc line; since the sub-heat exchanger 31 is formed into an open ring, the circumferential two ends of the sub-heat exchanger 31 are arranged at intervals, so that the circumferential two ends of the sub-heat exchanger 31 define an opening 311, and the wind deflector 32 is located at the two ends opening 311 of the sub-heat exchanger 31, thereby increasing the wind resistance at the opening 311, avoiding the airflow from easily passing through the opening 311, so that at least most of the airflow flows through the sub-heat exchanger 31 for heat exchange and then flows out through the air outlet 10a, further ensuring the cooling / heating efficiency of the air conditioner 100; at the same time, to a certain extent, the wind deflector 32 can exchange heat with the air, which is beneficial to increasing the heat exchange area of the heat exchange device 3.

[0058] Among them, the connection manner of the wind deflector 32 to other components of the air conditioner 100 is not specifically limited herein. For example, the wind deflector 32 can be directly connected to the sub-heat exchanger 31, or the wind deflector 32 can be directly connected to the housing 1, etc., as long as it is ensured that the wind deflector 32 is located at the two ends opening 311 of the sub-heat exchanger 31.

[0059] Optionally, the material for making the wind deflector 32 can be a material with a high heat transfer coefficient, such as copper, aluminum, etc. Thus, the heat exchange between the wind deflector 32 and the air can be utilized more effectively.

[0060] In some embodiments, through holes are formed in the wind deflector 32, so that the air inside the wind deflector 32 can flow to the outside of the wind deflector 32 through the through holes, thereby improving the air output of the air conditioner 100 on the premise of ensuring the heat exchange efficiency of the heat exchange device 3. Among them, there can be multiple through holes, and the arrangement of the multiple through holes is not specifically limited, and the wind deflector 32 can be formed into a micro-hole plate.

[0061] In other embodiments of the present invention, no through holes are formed in the wind deflector 32. At this time, the wind deflector 32 can be formed into a non-through-hole plate, so that the air inside the wind deflector 32 cannot pass through the wind deflector 32 and flow to the outside of the wind deflector 32, which is convenient for ensuring that all the air flowing into the housing 1 exchanges heat with the sub-heat exchanger 31.

[0062] Of course, the wind deflector 32 can also extend along a non-arc, for example, the wind deflector 32 can extend along a straight line, and the wind deflector 32 is located at the two ends of the opening 311 of the sub-heat exchanger 31.

[0063] In some alternative embodiments, as Figures 5-7 shown, the heat exchange device 3 includes a plurality of sub-heat exchangers 31, and the plurality of sub-heat exchangers 31 are spaced apart circumferentially around the impeller 2 to intermittently surround the impeller 2, which is beneficial to ensuring the heat exchange efficiency of the heat exchange device 3. At the same time, to a certain extent, it is convenient to reduce the extension length and bending angle of each sub-heat exchanger 31, facilitating the processing of the sub-heat exchanger 31. Moreover, the adjacent two sub-heat exchangers 31 are spaced apart, reducing the position accuracy requirements of the plurality of sub-heat exchangers 31, and facilitating the assembly of the air conditioner 100 on the premise of not affecting the heat exchange efficiency of the heat exchange device 3.

[0064] For example, in Figure 5 the example, the heat exchange device 3 includes two sub-heat exchangers 31, the two sub-heat exchangers 31 are spaced apart circumferentially around the impeller 2, and the two sub-heat exchangers 31 are arranged around the impeller 2. Each sub-heat exchanger 31 is arranged around the impeller 2 for half a circle, so that the two sub-heat exchangers 31 can intermittently surround the impeller 2 for a full circle; again, for example, in Figure 7 the example, the heat exchange device 3 includes two sub-heat exchangers 31, the two sub-heat exchangers 31 are spaced apart circumferentially around the impeller 2, and the two sub-heat exchangers 31 are arranged around the impeller 2. The cross-sectional shape of one of the sub-heat exchangers 31 is formed into a superior arc, and the cross-sectional shape of the other sub-heat exchanger 31 is formed into an inferior arc, and the two sub-heat exchangers 31 can intermittently surround the impeller 2 for a full circle.

[0065] It can be understood that when the heat exchange device 3 includes a plurality of sub-heat exchangers 31, the heat exchange device 3 may further include a wind deflector 32. For example, in Figure 6 In the example of Figure 6 , the heat exchange device 3 includes a wind deflector 32 and two sub-heat exchangers 31. The two sub-heat exchangers 31 are spaced apart along the circumferential direction of the wind wheel 2, and the two sub-heat exchangers 31 are arranged around the wind wheel 2 for less than one full circle, so that the cross-section of the two sub-heat exchangers 31 is substantially formed into an open ring to form an open pair 311, and the wind deflector 32 is arranged at the opening 311.

[0066] Of course, the number of sub-heat exchangers 31 may also be three or more; a plurality of sub-heat exchangers 31 may be intermittently arranged around the wind wheel 2 for one full circle, or a plurality of sub-heat exchangers 31 may be intermittently arranged around the wind wheel 2 for less than one full circle.

[0067] In some embodiments, as Figures 1-3 shown, the air conditioner 100 further includes a wind guiding device 4. The wind guiding device 4 is movably arranged at the air outlet 10a to adjust the air outlet direction of the air outlet 10a, which is beneficial to realizing 360° circumferential air outlet of the air conditioner 100, further avoiding the direct blowing of the air outlet of the air conditioner 100 to the user, and improving the user experience effect.

[0068] Among them, the specific movement mode of the wind guiding device 4 can be set according to actual needs, as long as it is ensured that the wind guiding device 4 can move to adjust the air outlet direction of the air outlet 10a; for example, the wind guiding device 4 is movably arranged at the air outlet 10a, or the wind guiding device 4 is rotatably arranged at the air outlet 10a, or the wind guiding device 4 is movable relative to the air outlet 10a at the air outlet 10a, and at the same time the wind guiding device 4 is rotatable relative to the air outlet 10a, but not limited thereto.

[0069] When the wind guiding device 4 is rotatable relative to the air outlet 10a, the wind guiding device 4 can be rotated by a driving motor and / or user driving, and the following situations are included: 1. The wind guiding device 4 is driven by a driving motor through a driving device 6; 2. The wind guiding device 4 is manually driven by the user to rotate; 3. The wind guiding device 4 can be driven to rotate by a driving motor and can also be manually driven by the user to rotate, making the use of the wind guiding device 4 more flexible.

[0070] Optionally, in Figures 1-3 In the example of Figures 1-3 , the wind guiding device 4 is configured to adjust the air outlet direction of the air outlet 10a along the circumferential direction of the housing 1, so that the wind guiding device 4 can change the air volume of the air outlet speed of the air conditioner 100 in the circumferential direction of the housing 1, thereby adjusting the air outlet direction of the air outlet 10a.

[0071] For example, the air guiding device 4 is formed as an air guiding plate 41. The air guiding plate 41 is rotatably arranged at the air outlet 10a, and one circumferential end of the air guiding plate 41 is rotatably connected to the edge of the air outlet 10a, so that the other circumferential end of the air guiding plate 41 can rotate around the above-mentioned circumferential end of the air guiding plate 41.

[0072] Optionally, in Figure 2 the example, the air guiding plate 41 is formed as the switch door of the air conditioner 100. At this time, the air guiding plate 41 can not only adjust the air outlet direction of the air outlet 10a, but also realize the opening and closing of the air outlet 10a. Among them, the maximum rotation angle of the air guiding plate 41 can be 40°. For example, the air guiding plate 41 can rotate within the range of 0° to 40° (including the end point values). When the air guiding plate 41 rotates to the 0° position, the air guiding plate 41 can close the air outlet 10a. When the air guiding plate 41 rotates to the 40° position, the air guiding plate 41 can be in the limit opening position; it can be understood that during the operation of the air guiding plate 41, the air guiding plate 41 can rotate within a certain angle range, or the air guiding plate 41 can always be in a certain angle position.

[0073] Of course, the air guiding plate 41 may not be formed as the switch door of the air conditioner 100. At this time, the air conditioner 100 can additionally provide a switch door at the air outlet 10a to realize the opening and closing of the air outlet 10a.

[0074] Optionally, the air guiding plate 41 can be formed as a curved surface plate, such as an arc plate, etc., to guide the air flow to flow smoothly and reduce the resistance loss.

[0075] Of course, the structure of the air guiding device 4 is not limited to this. The air guiding device 4 can also be configured to include a plurality of louvers. The plurality of louvers can be arranged at intervals along the circumferential direction of the air outlet 10a, or the air guiding device 4 can be configured as other air guiding structures.

[0076] In some embodiments, as Figure 8 and Figure 9 shown, the air conditioner 100 further includes a support device 5. The support device 5 is supported at one axial end of the housing 1, and the support device 5 is used to limit the installation angle of the housing 1 during use.

[0077] In Figure 2 and Figure 3 the example, a support connecting member 13 can be provided at the above-mentioned axial end of the housing 1. The support device 5 is supported on the support connecting member 13; the support connecting member 13 can include a plurality of support ribs. The outer end of each support rib is connected to the inner wall of the housing 1, and the inner ends of the plurality of support ribs are connected together, ensuring that the support connecting member 13 has sufficient structural strength. Of course, the structure of the support connecting member 13 is not limited to this.

[0078] Optionally, in Figure 8 andFigure 9 In the example, the air inlet 10b is formed at one axial end of the housing 1, and the support device 5 is supported at the above-mentioned axial end of the housing 1 through the support connecting member 13. Then, the support connecting member 13 will not affect the air intake at the air inlet 10b, ensuring the air intake volume of the air conditioner 100.

[0079] Wherein, the installation angle of the housing 1 for use can be the included angle α between the axis 10 of the housing 1 and the vertical direction, and α satisfies 0° ≤ α ≤ 30°, which is convenient for the smooth discharge of the condensed water of the air conditioner 100. For example, the air conditioner 100 can be provided with a water receiving tray. When the installation angle of the housing 1 for use is 0°, at least part of the surface of the water receiving tray is arranged obliquely with respect to the horizontal direction to guide the flow and discharge of the condensed water. When the installation angle of the housing 1 for use is 0° < α ≤ 30°, it is still possible to arrange at least part of the surface of the water receiving tray obliquely with respect to the horizontal direction to achieve the smooth discharge of the condensed water. However, it is not limited thereto.

[0080] Optionally, the support device 5 can be a support platform 51 or a support frame 52, etc. For example, in Figure 8 the example, the installation angle of the housing 1 for use is 0°, and the support platform 51 can be supported at the axial end of the housing 1 having the air inlet 10b, which is convenient for ensuring the support stability of the support device 5. The support platform 51 can be placed on a table, etc. Of course, the support platform 51 can also be supported at the axial end of the housing 1 away from the air inlet 10b. Another example is that in Figure 9 the example, the installation angle of the housing 1 for use is 0°, and the support frame 52 can be supported at the axial end of the housing 1 having the air inlet 10b. The support frame 52 can be bent and extended, and the end of the support frame 52 away from the housing 1 can be set on the wall, but it is not limited thereto. Of course, the support frame 52 can also be supported at the axial end of the housing 1 away from the air inlet 10b.

[0081] Optionally, the support device 5 can be provided on the wall, or the support device 5 can be provided on the table, but it is not limited thereto.

[0082] In some embodiments, as shown in Figure 8 and Figure 9 the air conditioner 100 further includes a driving device 6. The driving device 6 drives the housing 1 to rotate relative to the support device 5 around the axis 10 of the housing 1. Then, the air outlet 10a rotates relative to the support device 5 around the axis 10 of the housing 1, thereby adjusting the direction of the air outlet 10a, which is beneficial to realizing the 360° circumferential air outlet of the air conditioner 100, further avoiding the direct blowing of the air outlet of the air conditioner 100 to the user, and improving the user experience effect.

[0083] Wherein, the specific installation position of the driving device 6 can be set according to actual applications. For example, the driving device 6 can be provided on the support device 5, and the driving device 6 can be selected as a motor.

[0084] Optionally, the support device 5 is rotatably connected to the housing 1, and the heat exchange device 3 can remain relatively stationary with respect to the support device 5. Then, the heat exchange device 3 does not rotate with the rotation of the housing 1, avoiding the twisting of the refrigerant pipes connected to the heat exchange device 3. At the same time, there is no need to provide an avoidance structure for preventing the twisting of the refrigerant pipes, simplifying the structure of the air conditioner 100.

[0085] In some embodiments, as Figure 1 shown, the first axial end 10c of the housing 1 has multiple ring portions 11. The multiple ring portions 11 can be located on the wall surface of the end of the housing 1. The multiple ring portions 11 are concentrically arranged. Each ring portion 11 includes a plurality of light-transmitting regions 111 spaced apart along the circumferential direction of the housing 1. The air conditioner 100 further includes a light-emitting device 7 disposed opposite to each ring portion 11. The user can observe the light emitted by the light-emitting device 7 through the multiple light-transmitting regions 111, giving the air conditioner 100 a good visual effect.

[0086] Optionally, the light-emitting device 7 can have multiple light-emitting modes, and the light-emitting device 7 can achieve multi-scene light switching, further enhancing the visual effect of the air conditioner 100.

[0087] For example, in Figure 1 the example, the light-transmitting region 111 can be formed as a light-transmitting hole 1111, and the light-transmitting hole 1111 penetrates the wall surface of the first axial end 10c of the housing 1; the light-emitting device 7 can include a plurality of light-emitting sources, and the plurality of light-emitting sources are correspondingly arranged with the plurality of light-transmitting holes 1111. Among them, the light-emitting colors of the light-emitting devices 7 corresponding to two adjacent ring portions 11 are different, facilitating the realization of multi-scene lamp tube switching.

[0088] Optionally, the light-emitting device 7 can be disposed inside the housing 1. Thus, to a certain extent, the housing 1 can protect the light-emitting device 7. For example, it is convenient to achieve the insulation protection of the light-emitting device 7.

[0089] In some embodiments, as Figures 1-3As shown, the housing 1 is cylindrical, and the housing 1 can be formed into a straight cylindrical shape or an inclined cylindrical shape; there are multiple air outlets 10a, and the multiple air outlets 10a are spaced apart along the circumferential direction of the housing 1, which is beneficial to expanding the air supply range of the air conditioner 100, further avoiding excessive local air volume of the air conditioner 100, and at the same time being beneficial to the three-dimensional space circulation in the room, improving the indoor temperature uniformity, and improving the temperature adjustment efficiency of the air conditioner 100; the air inlet 10b is located at the second axial end 10d of the housing 1, so that the relative positions of the air inlet 10b and the air outlet 10a are reasonable, avoiding short-circuiting of the air outlet. The impeller 2 is a centrifugal impeller, and the axial direction of the impeller 2 is the axial direction of the housing 1, that is, the axial direction of the impeller 2 is parallel to the axial direction of the housing 1, so the central axis of the impeller 2 is parallel to or coincides with the axis 10 of the housing 1. Thus, the structure of the air conditioner 100 is simple, the layout is reasonable, it is convenient to realize the miniaturized design of the air conditioner 100, and at the same time it is beneficial to reducing the operating noise of the air conditioner 100, improving the sleep quality of users, and further improving the comfort level.

[0090] For example, in Figures 1-3 the example, the housing 1 is a straight cylindrical shape, there are four air outlets 10a, the four air outlets 10a are spaced apart along the circumferential direction of the housing 1, and a wind guiding device 4 can be provided at each air outlet 10a, and the wind guiding device 4 is used to adjust the air outlet direction of the corresponding air outlet 10a; when the air conditioner 100 operates, the centrifugal impeller rotates, a negative pressure is generated at the air inlet 10b, the air flow flows into the housing 1 along the axial direction of the housing 1 through the air inlet 10b, and sequentially flows through the impeller 2 and the heat exchange device 3 along the air flow path 10e, and finally the heat-exchanged gas flows out along the radial direction of the housing 1 through the air outlet 10a, and under the guiding action of the wind guiding device 4, the air flow at the air outlet 10a has a speed in the circumferential direction of the housing 1, realizing the circumferential air outlet of the air conditioner 100.

[0091] Optionally, the air conditioner 100 can be formed into an integrated air conditioner or a split air conditioner. For example, when the air conditioner 100 is an integrated air conditioner, the air conditioner 100 can be a window air conditioner 100 or a portable air conditioner 100, etc.; when the air conditioner 100 is a split air conditioner, the air conditioner 100 can include an indoor unit and an outdoor unit, and the housing 1 is the housing of the indoor unit.

[0092] In addition, the air conditioner 100 can also include a humidifying device, and the humidifying device is used to directly or indirectly deliver humidified air flow to the indoor environment, so that the air conditioner 100 has a humidifying function, can adjust the humidity of the indoor environment, and avoid skin dryness and the like caused by long-term use of the air conditioner 100.

[0093] It can be understood that the air conditioner 100 can also include a purification device, and the purification device is used to purify the indoor air, realizing the purification function of the air conditioner 100, which is beneficial to improving the indoor air quality.
