Description

Technical Field

[0001] This utility model relates to the field of air conditioning technology, and in particular to a ducted air conditioner and air conditioning unit. Background Technology

[0002] In some related technologies, ducted air conditioners use horizontal lateral airflow. In heating mode, the hot air is blown out horizontally. Because hot air has a lower density, it rises, and since people's heat needs are at a height of 1.6 meters or below, the hot air is difficult to deliver to the area where people are active, resulting in poor heating performance. In other related technologies, a downward airflow method is used. In cooling mode, cold air is blown directly onto people, resulting in poor comfort.

[0003] Existing technologies typically employ reverse fan rotation to achieve reverse airflow, enabling the ducted air conditioner to simultaneously deliver horizontal and vertical air. However, the airflow is relatively small when the fan rotates in reverse. If the ducted air conditioner is cooling when the fan is rotating forward, it needs to rotate in reverse when heating, resulting in poor heating capacity. Similarly, if the ducted air conditioner is heating when the fan is rotating forward, it needs to rotate in reverse when cooling, resulting in poor cooling capacity. Both solutions severely impact the heat exchange efficiency of the ducted air conditioner. Utility Model Content

[0004] In order to solve the technical problem that the heat exchange efficiency of the machine cannot be guaranteed by the fan reversal in the existing technology, a duct air conditioner and air conditioner is provided that uses a movable volute to adjust the air supply direction without adjusting the fan rotation to ensure heat exchange efficiency.

[0005] A ducted air conditioner, comprising:

[0006] The housing has a first side and a second side, a first air outlet is provided on the first side, and a second air outlet is provided on the second side;

[0007] A fan assembly, wherein the fan assembly is disposed within the housing;

[0008] The wind turbine assembly includes:

[0009] A fixed volute is provided with a first air outlet and a second air outlet, the air outlet of the first air outlet is directed toward the first air outlet, and the air outlet of the second air outlet is directed toward the second air outlet.

[0010] A movable volute is rotatably disposed within a fixed volute, and the movable volute has a first working state of opening the first air outlet and closing the second air outlet, and the movable volute also has a second working state of opening the second air outlet and closing the first air outlet.

[0011] When the movable volute is in the first working state or the second working state, the movable volute and the fixed volute form a complete volute-shaped structure.

[0012] Both the first air outlet and the second air outlet are disposed on the peripheral side of the fixed volute, and the included angle α formed between the line connecting the midpoint of the far end of the first air outlet and the axis of the fixed volute and the line connecting the midpoint of the far end of the second air outlet and the axis of the fixed volute is in the range of 50°≤α≤140°.

[0013] The included angle α is in the range of 90°≤α≤120°.

[0014] The duct unit also includes a drive mechanism, which is disposed on the housing and / or the fixed volute, and is connected to the movable volute.

[0015] A rack is provided on the peripheral side of the movable volute, and the drive gear of the drive mechanism meshes with the rack to drive the movable volute to move.

[0016] The movable volute is provided with a first air inlet and a rack on its end face. The rack is arranged in an arc shape around the first air inlet. The drive gear of the drive mechanism meshes with the rack to drive the movable volute to move.

[0017] The housing has a bottom plate and a vertical sidewall connected to the bottom plate. The bottom plate forms the second sidewall, and the vertical sidewall forms the first sidewall. The second air outlet is located on the portion of the bottom plate near the vertical sidewall.

[0018] The duct unit also includes a partition plate disposed inside the housing, which divides the interior of the housing into a heat exchange chamber and a fan chamber. The fan assembly is disposed inside the fan chamber, and the fan inlet of the fan assembly is connected to the fan chamber. The first air outlet and the second air outlet are both sealed relative to the fan chamber.

[0019] The housing is provided with a return air inlet, which is connected to the heat exchange chamber.

[0020] The ducted air conditioner has a cooling mode and a heating mode. The second side faces the ground. When the ducted air conditioner is in the cooling mode, the movable volute is in the first working state; when the ducted air conditioner is in the heating mode, the movable volute is in the second working state.

[0021] An air conditioner, including the aforementioned ducted unit.

[0022] The ducted air conditioner and air purifier provided by this utility model utilize a movable volute to open or close the first and second air outlets. This allows the air from the fan assembly to be delivered through either the first or second air outlet as needed, achieving the purpose of air delivery in different directions. It can achieve the purpose of horizontal cold air blowing for shower-like cooling and downward hot air blowing for carpet-like heating. At the same time, since the fan does not need to reverse, it overcomes the problem in the prior art that the air outlet direction of the ducted air conditioner can only be adjusted by changing the fan rotation direction. The ducted air conditioner can obtain reliable air volume in both cooling and heating modes, ensuring the heat exchange efficiency of the ducted air conditioner. Attached Figure Description

Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0039] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "setting," and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection, an indirect connection through an intermediate medium, or a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0040] Existing technologies typically employ reverse fan rotation to achieve reverse airflow, enabling the ducted air conditioner to simultaneously deliver horizontal and vertical air. However, the airflow is relatively small when the fan rotates in reverse. If the unit is cooling when the fan is rotating forward, it needs to rotate in reverse to heat, resulting in poor heating capacity. Similarly, if the unit is heating when the fan is rotating forward, it needs to rotate in reverse to cool, resulting in poor cooling capacity. Both solutions severely impact the heat exchange efficiency of the unit.

[0041] Therefore, this application provides a method such as Figures 1 to 10 The ducted air conditioner shown includes: a housing 1 having a first side 11 and a second side 12, a first air outlet 13 on the first side 11, and a second air outlet 14 on the second side 12; a fan assembly disposed within the housing 1, the fan assembly including: a fixed volute 2 having a first air inlet 21 and a second air outlet 22, the first air inlet 21 having an air outlet direction facing the first air outlet 13, and the second air outlet 22 having an air outlet direction facing the second air outlet 14; and a movable volute 3 rotatably disposed within the fixed volute 2, the movable volute 3 having a first working state of opening the first air outlet 21 and closing the second air outlet 22, and a second working state of opening the second air outlet 22 and closing the first air outlet 21. The movable volute 3 opens or closes the first air outlet 21 and the second air outlet 22, allowing the air from the fan assembly to be delivered through the first air outlet 13 or the second air outlet 14 as needed. This achieves the purpose of air delivery in different directions for the ducted air conditioner, enabling both horizontal blowing of cold air for shower-like cooling and downward blowing of hot air for carpet-like heating. Since the fan does not need to reverse, it overcomes the problem in existing technologies where the air outlet direction of the ducted air conditioner can only be adjusted by changing the fan rotation direction. The ducted air conditioner can obtain reliable air volume in both cooling and heating modes, ensuring the heat exchange efficiency of the ducted air conditioner.

[0042] The number of fan components can be two or more, and all the fan components are arranged side by side in the housing 1, and each fan component corresponds to a first air outlet 13 and a second air outlet 14.

[0043] When the movable volute 3 is in the first working state or the second working state, the movable volute 3 and the fixed volute 2 form a complete volute-shaped structure. This complete volute-shaped structure ensures that the fan assembly can reliably drive the gas in both the first and second working states, thereby guaranteeing the normal operation of the fan assembly. The ducted air conditioner can obtain reliable airflow in both cooling and heating modes, ensuring the heat exchange efficiency of the ducted air conditioner.

[0044] Preferably, the movable volute 3 is cylindrical in shape, with air passage holes on its sidewalls. The interior of the fixed volute 2 can communicate with the first air outlet 21 or the second air outlet 22 through these air passage holes. When the movable volute 3 is adjusted, the air passage holes also rotate. When the air passage holes are opposite to the first air outlet 21, the first air outlet 21 can supply air; when the air passage holes are opposite to the second air outlet 22, the second air outlet 22 can supply air. This achieves adjustment of the air outlet direction of the fan assembly. The interior of the fixed volute 2 forms a cylindrical cavity with the same shape as the movable volute 3. The axis of the cylindrical shape of the movable volute 3 is collinear with the axis of the cylindrical cavity, ensuring reliable rotation of the movable volute 3 within the fixed volute 2 and guaranteeing the operational reliability of the fan assembly.

[0045] Both the first air outlet 21 and the second air outlet 22 are disposed on the peripheral surface of the fixed volute 2, and the included angle α formed between the line connecting the distal midpoint of the first air outlet 21 to the axis of the fixed volute 2 and the line connecting the distal midpoint of the second air outlet 22 to the axis of the fixed volute 2 is in the range of 50°≤α≤140°. By limiting the included angle α, an angular difference exists between the air supply direction of the first air outlet 13 and the air supply direction of the second air outlet 14, thus reliably adjusting the air supply direction of the ducted air conditioner. When α < 50°, the air supply directions of the first air outlet 13 and the second air outlet 14 are relatively similar, and the effect of the duct air conditioner switching the air supply direction is not significant. However, when α > 140°, the air supply directions of the first air outlet 13 and the second air outlet 14 are basically opposite. For example, when the first air outlet 13 supplies air horizontally, the second air outlet 14 will also supply air horizontally in the opposite direction. This cannot achieve the purpose of blowing cold air horizontally for shower-like cooling and blowing hot air downwards for carpet-like heating. Only when 50° ≤ α ≤ 140° can the positions of the first air outlet 13 and the second air outlet 14 be reasonably set, and the purpose of blowing cold air horizontally for shower-like cooling and blowing hot air downwards for carpet-like heating can be achieved.

[0046] Preferably, the included angle α is in the range of 90°≤α≤120°, so that when the second air outlet 14 delivers air vertically downwards, the first air outlet 13 can deliver air horizontally or even obliquely upwards. When the ducted air conditioner is cooling, cold air can be blown horizontally through the first air outlet 13 or even blown close to the roof. The cold air flows to the ground under the action of gravity, achieving a shower-like cooling effect. When the ducted air conditioner is heating, hot air can be blown downwards through the second air outlet 14, quickly reaching the ground and spreading out on the ground, achieving a carpet-like heating effect, effectively improving the user experience of the ducted air conditioner.

[0047] The duct unit also includes a drive mechanism, which is disposed on the housing 1 and / or the fixed volute 2, and is connected to the movable volute 3. The drive mechanism enables automatic control of the movable volute 3, facilitating the switching of the movable volute 3 between the first working state and the second working state, thereby ensuring the reliability of the duct unit.

[0048] In one embodiment, a rack is provided on the peripheral side of the movable volute 3. The drive gear of the drive mechanism meshes with the rack to drive the movable volute 3 to move. By using the drive gear to drive the rack to move, the rack and the movable volute 3 can rotate around a set axis, thereby realizing the switching between the first working state and the second working state.

[0049] In another embodiment, the fixed volute 2 has a first air outlet 13 and a second air outlet 14 on its peripheral side. Therefore, the fixed volute 2 has a fan inlet on its end face. For this purpose, the movable volute 3 has a first air inlet 31 and a rack 32 on its end face. The rack 32 is arranged in an arc shape around the first air inlet 31. The drive gear of the drive mechanism meshes with the rack 32 to drive the movable volute 3 to move. Compared with the previous embodiment, the rack 32 is arranged on the end face of the movable volute 3. On the surface, the circumferential dimension of the movable volute 3 can be reduced, thereby reducing the size of the fan assembly and the duct machine. At the same time, since the movable volute 3 has a first air inlet 31 on its end face, the rack 32 is arranged in an arc shape around the first air inlet 31. This not only ensures the rotation of the movable volute 3 by utilizing the arc shape of the rack 32, but also facilitates the arrangement of the rack 32 and the first air inlet 31, preventing the rack 32 from blocking the first air inlet 31 and affecting the air intake effect of the fan assembly, thus ensuring the working reliability of the fan assembly.

[0050] The housing 1 has a base plate and a vertical sidewall connected to the base plate. The base plate forms the second side surface 12, and the vertical sidewall forms the first side surface 11. The first air outlet 13 on the vertical sidewall can deliver horizontal air, while the second air outlet 14 on the base plate can deliver vertical air. To minimize the distance between the first air outlet 21 and the second air outlet 22, the second air outlet 14 is located on the portion of the base plate closest to the vertical sidewall. This also reduces the distance between the first air outlet 21 and the second air outlet 22, thereby reducing the overall volume of the fan assembly and the ductwork unit.

[0051] The duct unit also includes a partition 4, which is disposed inside the housing 1 and divides the interior of the housing 1 into a heat exchange chamber 15 and a fan chamber 16. The fan assembly is disposed inside the fan chamber 16, and the fan inlet of the fan assembly is connected to the fan chamber 16. The first air outlet 13 and the second air outlet 14 are both sealed relative to the fan chamber 16. The fan cavity 16 restricts the air intake area of ​​the fan assembly, ensuring reliable air intake. Simultaneously, the relative seal between the first air outlet 13 and the fan cavity 16 allows the gas from the fan assembly to flow directly through the first air supply port 21 to the first air outlet 13 and ultimately be discharged outdoors when air is discharged from the first air outlet 13, ensuring the reliable operation of the ducted air conditioner. Similarly, the relative seal between the second air outlet 14 and the fan cavity 16 allows the gas from the fan assembly to flow directly through the second air supply port 22 to the second air outlet 14 and ultimately be discharged outdoors when air is discharged from the second air outlet 14, ensuring the reliable operation of the ducted air conditioner.

[0052] The housing 1 is provided with a return air inlet 17, which is connected to the heat exchange chamber 15. That is, the ducted air conditioner uses the return air inlet 17 for return air during operation. The return air first enters the heat exchange chamber 15 to exchange heat with the heat exchanger, and then flows into the fan chamber 16 to be drawn in by the fan assembly. Depending on the state of the movable volute 3, the air is either discharged through the first air outlet 13 or the second air outlet 14, thereby ensuring the reliability of the ducted air conditioner. At the same time, it also reduces the number of return air inlets 17, thereby reducing the need for filter structures and lowering the cost of the ducted air conditioner.

[0053] The ducted air conditioner has a cooling mode and a heating mode. The second side 12 faces the ground. When the ducted air conditioner is in the cooling mode, the movable volute 3 is in the first working state. At this time, the first air inlet 21 is connected to the first air outlet 13. The cold air generated by the ducted air conditioner during cooling will be blown out horizontally through the first air outlet 13 and then flow downward under the action of gravity to achieve a shower-like cooling. When the ducted air conditioner is in the heating mode, the movable volute 3 is in the second working state. The hot air can be blown downward through the second air outlet 14, quickly reach the ground and spread on the ground to achieve the purpose of carpet-like heating, effectively improving the user experience of the ducted air conditioner.

[0054] An air conditioner, including the aforementioned ducted unit.

[0055] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
