Description

Technical Field

[0001] The invention relates to the technical field of air conditioning, in particular to an air duct unit and an air conditioner. Background Art

[0002] In some related technologies, ducted air conditioners use horizontal lateral air supply. In heating mode, the hot air is blown out horizontally. Due to the low density of hot air, the hot air floats upward, and the heat demand of people is 1.6 meters or below. The hot air is difficult to reach the human activity area, resulting in poor heating effect. In other related technologies, the downward air supply method is used. In cooling mode, the cold air blows directly on the human body, which is less comfortable.

[0003] The prior art generally adopts the method of controlling the fan to reverse to achieve the reverse air outlet of the fan, so that the duct unit can simultaneously achieve the purpose of horizontal air supply and vertical air supply. However, the air volume is small when the fan is reversed. If the duct unit performs cooling when the fan rotates forward, the fan needs to be reversed when the duct unit performs heating, resulting in poor heating capacity of the duct unit. Similarly, if the duct unit performs heating when the fan rotates forward, the fan needs to be reversed when the duct unit performs cooling, resulting in poor cooling capacity of the duct unit. Both solutions will seriously affect the heat exchange efficiency of the duct unit. Summary of the invention

[0013] The angle α has an angle range of 90°≤α≤120°.

[0014] The air duct machine further comprises a driving mechanism, which is arranged on the housing and / or the fixed volute, and is connected to the movable volute.

[0015] A rack is arranged on the peripheral side surface of the movable volute, and the driving gear of the driving mechanism is meshed with the rack to drive the movable volute to move.

[0016] A first air inlet and a rack are arranged on the end surface of the movable volute. The rack is arranged in an arc shape on the circumference of the first air inlet. The driving gear of the driving mechanism is meshed with the rack to drive the movable volute to move.

[0018] The duct machine also includes a partition, which is arranged in the shell, and the partition divides the interior of the shell into a heat exchange chamber and a fan chamber. The fan assembly is arranged in the fan chamber, and the fan inlet of the fan assembly is connected to the fan chamber, and the first air outlet and the second air outlet are relatively sealed from the fan chamber.

[0019] The shell is provided with an air return port, and the air return port is communicated with the heat exchange cavity.

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

[0021] An air conditioner comprises the above-mentioned duct air conditioner.

For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0040] The prior art generally adopts the method of controlling the fan to reverse to achieve the reverse air outlet of the fan, so that the duct air conditioner can simultaneously achieve the purpose of horizontal air supply and vertical air supply. However, the air volume is small when the fan is reversed. If the fan is rotated forward for cooling, the fan needs to be reversed when the machine is heated, resulting in poor heating capacity of the machine. Similarly, if the fan is rotated forward for heating, the fan needs to be reversed when the machine is cooled, resulting in poor cooling capacity of the machine. Both solutions will seriously affect the heat exchange efficiency of the machine.

[0041] To this end, the present application provides a Figures 1 to 10 The duct dryer shown in the figure comprises: a shell 1, the shell 1 has a first side surface 11 and a second side surface 12, the first side surface 11 is provided with a first air outlet 13, and the second side surface 12 is provided with a second air outlet 14; a fan assembly, the fan assembly is arranged in the shell 1, and the fan assembly comprises: a fixed volute 2, the fixed volute 2 is provided with a first air supply port 21 and a second air supply port 22, the air outlet direction of the first air supply port 21 is toward the first air outlet 13, and the air outlet direction of the second air supply port 22 is toward the second air outlet 14; a movable volute 3, the movable volute 3 is rotatably arranged in the fixed volute 2, and the movable volute 3 has a first working state in which the first air supply port 21 is opened and the second air supply port 22 is closed, and the movable volute 3 also has a second working state in which the second air supply port 22 is opened and the first air supply port 21 is closed. The movable volute 3 is used to open or close the first air supply port 21 and the second air supply port 22, so that the air outlet of the fan assembly can be supplied through the first air outlet 13 or the second air outlet 14 as needed, thereby achieving the purpose of supplying air in different directions of the duct machine, and can achieve the purpose of blowing cold air horizontally for bathing-style cooling and blowing hot air downward for carpet-style heating. At the same time, since the fan does not need to be reversed, the problem in the prior art that the air outlet direction of the duct machine can only be adjusted by changing the direction of the fan is overcome. The duct machine can obtain reliable air volume in both cooling mode and heating mode, thereby ensuring the heat exchange efficiency of the duct machine.

[0042] The number of the fan components may be two or more, all of which are arranged in parallel 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 in the second working state, the movable volute 3 and the fixed volute 2 form a complete volute-like structure. By forming a complete volute-like structure, the fan assembly can reliably drive the gas in the first working state or the second working state, thereby ensuring the normal operation of the fan assembly, and the duct air conditioner can obtain reliable air volume in the cooling mode or the heating mode, ensuring the heat exchange efficiency of the duct air conditioner.

[0044] Preferably, the movable volute 3 is cylindrical in shape, and an air hole is provided on the cylindrical side wall, and the interior of the fixed volute 2 can be connected with the first air supply port 21 or the second air supply port 22 through the air hole. When the movable volute 3 is adjusted, the air hole also rotates, and when the air hole is opposite to the first air supply port 21, the first air supply port 21 can supply air, and when the air hole is opposite to the second air supply port 22, the second air supply port 22 can supply air, thereby realizing the adjustment of the air outlet direction of the fan assembly, wherein the interior of the fixed volute 2 forms a cylindrical cavity with the same shape as the movable volute 3, and the axis of the cylindrical shape of the movable volute 3 is colinear with the axis of the cylindrical cavity, thereby ensuring the reliable rotation of the movable volute 3 in the fixed volute 2 and ensuring the working reliability of the fan assembly.

[0045] The first air supply port 21 and the second air supply port 22 are both arranged on the peripheral side surface of the fixed volute 2, and the angle α formed between the line connecting the distal midpoint of the first air supply port 21 and the axis of the fixed volute 2 and the line connecting the distal midpoint of the second air supply port 22 and the axis of the fixed volute 2 is in the range of 50°≤α≤140°. By limiting the angle α, there is an angle difference between the air supply direction of the first air outlet 13 and the air supply direction of the second air outlet 14, and the air supply direction of the duct air conditioner can be reliably adjusted. When α<50°, the difference between the air supply directions of the first air outlet 13 and the second air outlet 14 is relatively small, and the effect of switching the air supply direction of the duct air conditioner is not significant; and 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, and the purpose of horizontal blowing of cold air for bathing-style cooling and downward blowing of hot air for carpet-style heating cannot be achieved. 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 horizontal blowing of cold air for bathing-style cooling and downward blowing of hot air for carpet-style heating can be achieved.

[0046] Preferably, the angle α ranges from 90°≤α≤120°, so that when the second air outlet 14 supplies air vertically downward, the first air outlet 13 can supply air horizontally or even diagonally upward. When the duct machine is cooling, cold air can be blown out horizontally through the first air outlet 13 or even close to the roof. The cold air flows to the ground under the action of gravity, realizing bathing-style cooling. When the duct machine is heating, hot air can be blown downward through the second air outlet 14, quickly reach the ground and spread on the ground, realizing the purpose of carpet-style heating, effectively improving the user experience of the duct machine.

[0047] The duct machine also includes a driving mechanism, which is arranged on the shell 1 and / or the fixed volute 2, and is connected to the movable volute 3. The driving mechanism is used to realize automatic control of the movable volute 3, which facilitates the switching of the movable volute 3 between the first working state and the second working state, thereby ensuring the working reliability of the duct machine.

[0048] As an embodiment, a rack is provided on the peripheral side surface of the movable volute 3, and the driving gear of the driving mechanism is engaged with the rack to drive the movable volute 3 to move. The driving gear is used to drive the rack to move, so that the rack and the movable volute 3 can rotate along a set axis, thereby realizing switching between the first working state and the second working state.

[0049] As another embodiment, the fixed volute 2 is provided with a first air outlet 13 and a second air outlet 14 on the peripheral side surface. Therefore, the fixed volute 2 is provided with a fan air inlet on the end surface. For this purpose, the end surface of the movable volute 3 is provided with a first air inlet 31 and a rack 32. The rack 32 is arranged in an arc shape on the peripheral side of the first air inlet 31. The driving gear of the driving mechanism is engaged with the rack 32 to drive the movable volute 3 to move. Compared with the previous embodiment, the rack 32 is arranged at the end of the movable volute 3. At the same time, since the movable volute 3 is provided with a first air inlet 31 on the end face, the rack 32 is arranged in an arc shape on the circumferential side of the first air inlet 31, which can not only ensure the rotation of the movable volute 3 by utilizing the arc shape of the rack 32, but also facilitate the arrangement of the rack 32 and the first air inlet 31, thereby avoiding the rack 32 blocking the first air inlet 31 and affecting the air intake effect of the fan assembly, thereby ensuring the working reliability of the fan assembly.

[0050] The housing 1 has a bottom plate and a vertical side wall connected to the bottom plate, the bottom plate constitutes the second side surface 12, and the vertical side wall constitutes the first side surface 11. At this time, the first air outlet 13 on the vertical side wall can supply air horizontally, and the second air outlet 14 on the bottom plate can supply air vertically. In order 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 part of the bottom plate close to the vertical side wall. At this time, the distance between the first air outlet 21 and the second air outlet 22 can also be reduced, thereby reducing the overall volume of the fan assembly and the air duct machine.

[0051] The duct machine also includes a partition 4, which is arranged in the shell 1, and the partition 4 divides the interior of the shell 1 into a heat exchange chamber 15 and a fan chamber 16. The fan assembly is arranged in the fan chamber 16, and the fan air 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 relatively sealed with the fan chamber 16. The fan cavity 16 is used to limit the air inlet area of ​​the fan assembly to ensure that the fan assembly can reliably take in air. At the same time, the relative seal between the first air outlet 13 and the fan cavity 16 is utilized so that when the first air outlet 13 is discharging air, the gas of the fan assembly can directly flow to the first air outlet 13 through the first air supply port 21 and be finally discharged to the outdoors, thereby ensuring the working reliability of the duct air conditioner. Similarly, the relative seal between the second air outlet 14 and the fan cavity 16 is utilized so that when the second air outlet 14 is discharging air, the gas of the fan assembly can directly flow to the second air outlet 14 through the second air supply port 22 and be finally discharged to the outdoors, thereby ensuring the working reliability of the duct air conditioner.

[0052] The housing 1 is provided with a return air port 17, which is in communication with the heat exchange chamber 15. That is, the duct air conditioner uses the return air port 17 for returning air when working, and 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 sucked in by the fan assembly, and the first air outlet 13 or the second air outlet 14 is selected to discharge air according to the state of the movable volute 3, thereby ensuring the working reliability of the duct air conditioner, and at the same time reducing the number of return air ports 17 and the setting of the filtering structure, thereby reducing the cost of the duct air conditioner.

[0053] The duct dryer has a cooling mode and a heating mode, and the second side surface 12 faces the ground. When the duct dryer is in the cooling mode, the movable volute 3 is in the first working state, and the first air supply port 21 is connected to the first air outlet 13. The cold air generated when the duct dryer is cooling will be blown out horizontally through the first air outlet 13, and then flow downward under the action of gravity to achieve bathing-type cooling; when the duct dryer is in the heating mode, the movable volute 3 is in the second working state, and the hot air can be blown out downward through the second air outlet 14, quickly reach the ground and spread on the ground, achieving the purpose of carpet-type heating, effectively improving the user experience of the duct dryer.

[0054] An air conditioner comprises the above-mentioned duct air conditioner.

[0055] The above-mentioned embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the present invention. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
