[0038] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0039] The following is for reference. Figures 1-7 This invention describes an air conditioner according to an embodiment of the present invention.

[0040] The air conditioner according to an embodiment of the present utility model, with reference to... Figures 1-7 The system includes a housing 10, a heat exchanger assembly 20, and an air duct assembly 30. An air inlet structure 11 is formed at the rear of the housing 10, and an air outlet structure is formed at the front of the housing 10. The air outlet structure includes a first air outlet 12 and two second air outlets 13, with the first air outlet 12 located above the second air outlets 13. By including the first air outlet 12 and two second air outlets 13 in the air outlet structure, the air outlet range of the air conditioner can be widened, the air volume of the air conditioner can be increased, and the performance of the air conditioner can be improved.

[0041] For example, the first air outlet 12 can be located in the central area of ​​the front of the air conditioner. When the air conditioner is working, the air from the first air outlet 12 can be concentrated and directed towards the central area of ​​the front of the air conditioner, making the air conditioner better able to regulate the temperature of the central area of ​​the front. The two second air outlets 13 can be located at the left and right ends of the front of the air conditioner, respectively. When the air conditioner is working, the two second air outlets 13 can supplement and regulate the temperature of the left and right sides of the air conditioner, and can also prevent the air from blowing directly onto the user's legs, thus improving the user's comfort.

[0042] The heat exchanger assembly 20 is housed within the casing 10, and the air duct assembly 30 is housed within the casing 10 and located between the air outlet structure and the heat exchanger assembly 20. The air duct assembly 30 includes two air duct components 31 arranged at intervals along the vertical direction. Each air duct component 31 includes an air duct volute 32 and a centrifugal impeller 33 disposed within the air duct volute 32. At least one side of the air duct volute 32 in the vertical direction forms an airflow inlet 34. Compared to using a cross-flow impeller, using multiple centrifugal impellers 33 arranged vertically can reduce the overall height of the unit in the vertical direction while maintaining the same maximum airflow, saving space and facilitating the handling or placement of the air conditioner.

[0043] For example, an airflow inlet 34 is formed on the upper side of the duct volute 32, and an airflow outlet 34a is formed on the front side of the duct volute 32. When the centrifugal impeller 33 is working, the centrifugal impeller 33 drives the airflow to enter the vicinity of the centrifugal impeller 33 from the airflow inlet 34 on the upper side of the duct volute 32, i.e., in the axial direction of the centrifugal impeller 33. The airflow is then thrown out by the centrifugal impeller 33 in the radial direction, leaves the centrifugal impeller 33 from the airflow outlet 34a, and leaves the air conditioner from the air outlet.

[0044] For example, an airflow inlet 34 is formed on the lower side of the duct volute 32, and an airflow outlet 34a is formed on the front side of the duct volute 32. When the centrifugal impeller 33 is working, the centrifugal impeller 33 drives the airflow to enter the vicinity of the centrifugal impeller 33 from the airflow inlet 34 on the lower side of the duct volute 32, i.e., in the axial direction of the centrifugal impeller 33. The airflow is then thrown out by the centrifugal impeller 33 along the radial direction of the centrifugal impeller 33, leaves the centrifugal impeller 33 from the airflow outlet 34a, and leaves the air conditioner from the air outlet.

[0045] For example, airflow inlets 34 are formed on the upper and lower sides of the duct volute 32, and airflow outlets 34a are formed on the front side of the duct volute 32. When the centrifugal impeller 33 is working, the centrifugal impeller 33 drives the airflow to enter the vicinity of the centrifugal impeller 33 from the two airflow inlets 34 on the upper and lower sides of the duct volute 32, and then throws it out radially along the centrifugal impeller 33, leaving the centrifugal impeller 33 from the airflow outlet 34a, and leaving the air conditioner from the air outlet.

[0046] The two air duct components 31 are a first air duct component 35 and a second air duct component 36, respectively. The first air duct component 35 is located above the second air duct component 36. The air duct housing 32 of the first air duct component 35 has a first air outlet 37, and the air duct housing 32 of the second air duct component 36 has two second air outlets 40 spaced apart in the left-right direction. The air outlet side of the first air outlet 37 corresponds to and is connected to the first air outlet 12, and the air outlet sides of the two second air outlets 40 correspond to and are connected to the two second air outlets 13, respectively. By aligning and connecting the air outlet side of the first air outlet 37 to the first air outlet 12, and the air outlet sides of the two second air outlets 40 to and from the two second air outlets 13, the air conditioner can have a larger air outlet range and air volume, thus improving the performance of the air conditioner.

[0047] For example, the air conditioner is a split-type floor-standing air conditioner, which includes an indoor unit 100 and an outdoor unit. The indoor unit 100 includes the aforementioned casing 10, heat exchanger assembly 20, and air duct assembly 30, and the rotation axis of the fan wheel extends in the vertical direction. When the air conditioner is running, the fan rotates around its axis of rotation, driving air to enter the housing 10 from the air inlet on the rear side of the housing 10. After the airflow passes through the heat exchanger assembly 20 and exchanges heat with it, the fan drives the airflow to enter the vicinity of the fan from the airflow inlet 34, and then is thrown out radially by the centrifugal fan 33, leaving the centrifugal fan 33 from the airflow outlet 34a. The air thrown out by the upper centrifugal fan 33 enters the first air duct component 35, and finally leaves the air conditioner through the first air outlet 12 on the front side of the housing 10; the air thrown out by the lower centrifugal fan 33 enters the second air duct component 36, and finally leaves the air conditioner through the two second air outlets 13 on the front side of the housing 10, thereby regulating the indoor temperature.

[0048] According to the embodiment of the present invention, the air conditioner includes two duct components 31 arranged at intervals in the vertical direction in the duct assembly 30. Each duct component 31 includes a duct volute 32 and a centrifugal impeller 33 disposed in the duct volute 32. Compared with the cross-flow fan in the related art, the vertical dimension of the air conditioner can be reduced while maintaining the same maximum air volume, so as to facilitate the transportation or placement of the air conditioner. Furthermore, by making the air outlet side of the first air outlet duct 37 correspond to and communicate with the first air outlet 12, and the air outlet sides of the two second air outlet ducts 40 correspond to and communicate with the two second air outlets 13 respectively, the air conditioner can have a larger air outlet range and air volume, thereby improving the performance of the air conditioner.

[0049] According to some embodiments of this utility model, refer to Figure 5 and Figure 6 The projections of the two second air outlets 13 on the horizontal plane are located to the left and right of the projection of the first air outlet 12 on the horizontal plane. By placing the projections of the two second air outlets 13 on the horizontal plane to the left and right of the projection of the first air outlet 12 on the horizontal plane, the air blown from the two second air outlets 13 can be closer to the left and right sides of the air conditioner than the first air outlet 12, giving the air conditioner a larger air outlet range in the left and right directions. Furthermore, since the two second air outlets 13 are located below the first air outlet 12, the air blown from the two second air outlets 13 is closer to the left and right sides of the air conditioner, which can prevent this part of the air from blowing directly on the legs and enhance the user experience.

[0050] According to some embodiments of this utility model, refer to Figures 4-6 The casing 10 has a rectangular cross-section. The first air outlet 12 is located on the front side of the casing 10, and the two second air outlets 13 are located at the left and right corners of the casing 10, respectively. By placing the first air outlet 12 on the front side of the casing 10, the air outlet 12 can be concentrated to deliver air to the front area of ​​the air conditioner, enhancing the air conditioner's temperature control capability for the front area. By placing the two second air outlets 13 at the left and right corners of the casing 10, the two second air outlets 13 can be concentrated to deliver air to the sides of the air conditioner, increasing the airflow range of the air conditioner. Furthermore, since the second air outlets 13 are located below the first air outlet 12, delivering air to the sides of the air conditioner also avoids direct airflow onto the legs, improving the user experience.

[0051] According to some embodiments of this utility model, refer to Figure 1 and Figure 2 The flow area of ​​the first air outlet duct 37 is larger than that of a single second air outlet duct 40. By making the flow area of ​​the first air outlet duct 37 larger than that of a single second air outlet duct 40, the air volume of the first air outlet duct 37 can be increased, and the air conditioner can better regulate the temperature of the upper area.

[0052] According to some embodiments of this utility model, refer to Figure 1 and Figure 2 The air outlet area of ​​the first air outlet 12 is greater than the sum of the air outlet areas of the two second air outlets 13. By making the flow area of ​​the first air outlet channel 37 greater than the flow area of ​​a single second air outlet channel 40, the air volume of the first air outlet channel 37 can be increased, and the air conditioner can better regulate the temperature of the upper area.

[0053] According to some embodiments of this utility model, refer to Figure 4 The first air outlet duct 37 has a first air outlet sidewall 38 and a second air outlet sidewall 39 arranged opposite each other in the vertical direction. The first air outlet sidewall 38 is located above the second air outlet sidewall 39. The first air outlet sidewall 38 extends upward in a rear-to-front direction, and the second air outlet sidewall 39 extends downward in a rear-to-front direction. By making the first air outlet sidewall 38 extend upward in a rear-to-front direction and the second air outlet sidewall 39 extend downward in a rear-to-front direction, the first air outlet sidewall 38 and the second air outlet sidewall 39 can form a funnel shape, increasing the air outlet area at the end of the first air outlet duct 37; and correspondingly, the area of ​​the first air outlet 12 can be increased. The first air outlet end combined with the larger first air outlet 12 can increase the air outlet range of the air conditioner.

[0054] According to some embodiments of this utility model, refer to Figure 6 The included angle between the two second air outlet channels 40 is α, and the value of α ranges from 120° to 180°. For example, the included angle α of the two second air outlet channels 40 can be 120°, 135°, 150°, 175°, 180°, etc. By ensuring that the included angle α of the two second air outlet channels 40 is not less than 120°, the two second air outlets 13 can fully regulate the temperature of the areas on both sides of the air conditioner, and can more effectively prevent the air blown from the second air outlets 13 from blowing directly onto the legs; by ensuring that the included angle α of the two second air outlet channels 40 is not greater than 180°, it can prevent the air conditioner from blowing air to the rear and directly sucking it into the air inlet.

[0055] According to some embodiments of this utility model, refer to Figure 2The width of the second air outlet 13 in the circumferential direction of the casing 10 is x, and the value of x ranges from 50mm to 100mm. For example, the value of x can be 50mm, 60mm, 70mm, 80mm, 90mm, 100mm, etc. By ensuring that the value of the width x of the second air outlet 13 in the circumferential direction of the casing 10 is not less than 50mm, the two second air outlets 13 can fully regulate the temperature of the areas on both sides of the air conditioner; by ensuring that the value of the width x of the second air outlet 13 in the circumferential direction of the casing 10 is not greater than 100mm, the air conditioner does not need to be correspondingly enlarged in the left and right directions, which is conducive to the miniaturization of the air conditioner.

[0056] According to some embodiments of this utility model, refer to Figure 1 The vertical distance between the lower edge of the second air outlet 13 and the bottom surface of the casing 10 is L1, and L1 is greater than 1000mm. For example, the value of L1 can be 1100mm, 1200mm, 1300mm, 1400mm, etc. By making the value of L1 greater than 1000mm, the air outlet can be positioned higher, which can more effectively regulate the temperature of the user's upper body, making the user more comfortable; and it also avoids the air blown from the air outlet blowing directly on the legs, enhancing the user experience.

[0057] According to some embodiments of this utility model, refer to Figure 1 and Figure 2 The air conditioner includes a first air guide plate 50 and a second air guide plate 52 rotatably mounted on the housing 10. The first air guide plate 50 is used to open and close the first air outlet 12, and the second air guide plate 52 is used to open and close the second air outlet 13. By including the first air guide plate 50 and the second air guide plate 52 rotatably mounted on the housing 10, the first air guide plate 50 can guide the airflow from the first air outlet 12, and the second air guide plate 52 can guide the airflow from the second air outlet 13, allowing the airflow to flow along the first air guide plate 50 or the second air guide plate 52. By making the first air guide plate 50 and the second air guide plate 52 rotatable, the direction of the airflow at the air outlet can be adjusted by the first air guide plate 50 or the second air guide plate 52.

[0058] According to some embodiments of this utility model, there are multiple first air guide plates 50 arranged in the left-right direction. By having multiple first air guide plates 50 arranged in the left-right direction, the airflow blown from the first air outlet 12 can be guided by the first air guide plates 50 in both the left and right directions, which can make the air guide plates more effective in guiding the airflow.

[0059] According to some embodiments of this utility model, the rotation axis of the first air guide plate 50 extends in the vertical direction. By extending the rotation axis of the first air guide plate 50 in the vertical direction, the first air guide plate 50 can swing in the left and right direction during operation, and the airflow in the left and right directions can be adjusted.

[0060] For example, the rotation axes of the first air guide plate 50 and the second air guide plate 52 both extend in the vertical direction. When working, the first air guide plate 50 and the second air guide plate 52 can swing in the left and right direction, and the air outlet in the left and right direction can be adjusted.

[0061] According to some embodiments of this utility model, refer to Figure 1 and Figure 2 The air conditioner includes a first air guide plate 50 rotatably disposed on the housing 10. The first air guide plate 50 is used to open and close the first air outlet 12, and a plurality of first air diffusers 51 are formed on the first air guide plate 50. By forming a plurality of first air diffusers 51 on the first air guide plate 50, when the first air guide plate 50 is in the closed state, airflow can be blown out from the plurality of first air diffusers 51 to achieve the effect of improving air temperature without a draft, thereby enhancing the user experience.

[0062] According to some embodiments of this utility model, refer to Figure 1 and Figure 6 The air outlet structure also includes a third air outlet 14, which is located directly below the first air outlet 12 and between the two second air outlets 13. The third air outlet 14 can be selectively connected to or separated from the second air outlet duct 40. By positioning the third air outlet 14 directly below the first air outlet 12 and between the two second air outlets 13, the air blown from the third air outlet 14 can be concentrated and directed towards the front of the air conditioner, improving the air conditioner's temperature regulation capability for the front area. By selectively connecting or separating the third air outlet 14 from the second air outlet duct 40, users can selectively improve the air conditioner's temperature regulation capability for the front area, or direct the lower air outlets of the air conditioner towards the sides to prevent air from blowing directly onto their legs.

[0063] According to some embodiments of this utility model, refer to Figure 5 and Figure 6A connecting ventilation cavity 41 is defined between the front side of the second air duct component 36 and the front part of the housing 10. The connecting ventilation cavity 41 is connected to the third air outlet 14, and the connecting ventilation cavity 41 can be selectively connected to or disconnected from the second air outlet channel 40. By defining the connecting ventilation cavity 41 between the front side of the second air duct component 36 and the front part of the housing 10, and by selectively connecting or disconnecting the connecting ventilation cavity 41 from the second air outlet channel 40, the air blown from the second air duct component 36 can either be blown out from the third air outlet 14 or not. The user can adjust whether the third air outlet 14 blows air according to their own needs.

[0064] According to some embodiments of this utility model, refer to Figure 5 and Figure 6 The ventilation cavity 41 and the second air outlet duct 40 are adapted to be connected through the connecting port 42. The air conditioner includes a second air guide plate 52 disposed on the housing 10. The second air guide plate 52 is rotatable between a first position and a second position. In the first position, the second air guide plate 52 closes the second air outlet 13 and opens the connecting port 42. In the second position, the second air guide plate 52 opens the second air outlet 13 and closes the connecting port 42. When the second air guide plate 52 is in the first position, by closing the second air outlet 13 and opening the connecting port 42, the air blown out by the second air duct component 36 can pass through the connecting ventilation cavity 41 and then be blown out of the air conditioner through the third air outlet 14. The second air outlet 13 does not blow air, and the air conditioner can concentrate the airflow towards the front, making the air conditioner's temperature regulation capability for the front area more significant. When the second air guide plate 52 is in the second position, by opening the second air outlet 13 and closing the connecting port 42, the air blown out by the second air duct component 36 can be blown out of the air conditioner from the second air outlet 13, and the third air outlet 14 does not blow air. At this time, the air conditioner can deliver airflow from both sides and avoid this part of the air blowing directly on the legs, improving the user experience.

[0065] According to some embodiments of this utility model, refer to Figure 5 and Figure 6 The third air outlet 14 includes a plurality of second air diffusers 15 formed on the housing 10. By including a plurality of second air diffusers 15 formed on the housing 10 on the third air outlet 14, when the second air guide plate 52 is in the first position, airflow can be blown out from the plurality of second air diffusers 15 to achieve the effect of improving air temperature without a wind sensation, thereby enhancing the user experience; furthermore, by including second air diffusers 15 in the third air outlet 14 that can achieve the effect of eliminating a wind sensation, this can prevent this part of the air from blowing directly on the legs, thereby enhancing the user experience.

[0066] According to some embodiments of this utility model, refer to Figure 2The third air outlet 14 has a height of 'a' in the vertical direction and a width of 'b' in the horizontal direction, with both 'a' and 'b' ranging from 200mm to 300mm. For example, 'a' can be 200mm, 220mm, 240mm, 260mm, 280mm, or 300mm, and 'b' can be 200mm, 220mm, 240mm, 260mm, 280mm, or 300mm. By ensuring that 'a' and 'b' are not less than 200mm, the air outlet 14 can provide a sufficient airflow range, enabling more effective temperature regulation in the area in front of the air conditioner. By ensuring that 'a' and 'b' are not less than 300mm, the air conditioner does not need to be enlarged in the horizontal direction, which is beneficial for miniaturization.

[0067] According to some embodiments of this utility model, refer to Figure 7 The centrifugal impellers 33 of the two air duct components 31 share a single motor 60, which is located between the two centrifugal impellers 33 in the vertical direction.
