Description

TECHNICAL FIELD

[0001] The utility model relates to air conditioning technical field, especially air conditioner. BACKGROUND

[0002] In the field of air conditioning technology, the design of traditional air conditioners generally adopts fixed air outlet and air return position to simplify system structure and reduce manufacturing cost. However, this design method is not satisfactory when facing the problem of uneven indoor air temperature distribution. Because of the obvious stratification phenomenon of indoor air temperature along the height direction, i.e. the air with high temperature rises and gathers in the upper part of the room due to its small density, while the air with low temperature sinks and gathers in the bottom of the room due to its large density, this thermal stratification phenomenon makes it difficult for traditional air conditioners to achieve good energy saving effect and comfort experience under both cooling and heating conditions.

[0003] Taking the cabinet type air conditioner with air outlet above and air return below as an example, the air outlet is usually located at the upper part of the air conditioner, which is relatively high. When cooling in summer, cold air is quickly injected into the room through the air outlet, and because the cold air flow has large density, it can naturally sink and cover the human activity area, thereby realizing rapid cooling and reducing the blowing feeling, and taking into account the cooling effect and comfort. At the same time, because the air return is located at the lower part of the air conditioner, the return air temperature is relatively low, about 2℃ lower than the middle and upper parts, so the energy saving effect is good.

[0004] However, when heating in winter, the problem of this design method is highlighted. Due to the principle of hot air rising, hot jet flow gathers in the upper part of the room, which is difficult to reach the lower space, resulting in the phenomenon of hot in the upper part and cold in the lower part. At this time, although the lower return air temperature is still about 2℃ lower than the middle and upper parts, in order to achieve the same outlet air temperature, the air conditioner needs to consume more energy, and the energy saving effect is greatly discounted.

[0005] Therefore, the traditional one-way air inlet and outlet circulation mode has obvious limitations under both cooling and heating conditions. In cooling mode, although cold air can quickly cover the human activity area, the temperature drop rate of the upper space in the room is slow, resulting in uneven overall cooling and poor user comfort; while in heating mode, warm air is difficult to reach the bottom space in the room, which makes the bottom temperature too low, affecting the comfort and energy saving effect.

[0035] Please refer to Figures 1-5 The present embodiment provides an air conditioner, comprising: a panel component 1, an air duct component 2 and an evaporator component 3, the panel component 1 is provided with a first air inlet 4, an air passage 5 and a second air inlet 6 which are sequentially communicated, the air duct component 2 and the evaporator component 3 are both arranged in the air passage 5, and the air duct component 2 is provided with a plurality of baffles to achieve respective opening and closing when the air duct component 2 performs upper air outlet or lower air outlet.

[0036] The present embodiment realizes upper air inlet and lower air outlet during heating and lower air inlet and upper air outlet during cooling by arranging the air duct component 2 and the evaporator component 3 in the air passage 5, and realizes switching of different air supply modes of the air conditioner by arranging the plurality of baffles, thereby avoiding the problem of slow temperature drop rate of the upper space in the room during cooling, and improving overall cooling efficiency and comfort. It is ensured that sufficient heat can be obtained in the bottom space in the heating mode, and overall comfort and energy saving effect are improved.

[0037] When the user selects the cooling mode, the air duct component 2 is activated, and the corresponding baffles are opened and closed. Then, air enters from the second air outlet 6 at the bottom, passes through the evaporator component 3 to be cooled, and then the cooled air is discharged from the first air outlet 4 at the top. When the user selects the heating mode, the air duct component 2 is activated, and the corresponding baffles are opened and closed. Then, air enters from the first air outlet 4 at the top and is heated, and then the heated air is discharged from the second air outlet 6 at the bottom.

[0038] In some embodiments, the ventilation channel 5 includes a first ventilation channel 7 and a second ventilation channel 8, the first air outlet 4, the first ventilation channel 7, the second ventilation channel 8, and the second air outlet 6 are sequentially connected, the air duct component 2 is arranged in the first ventilation channel 7, and the evaporator component 3 is arranged in the second ventilation channel 8.

[0039] By arranging the first ventilation channel 7 and the second ventilation channel 8, and sequentially connecting the first air outlet 4, the first ventilation channel 7, the second ventilation channel 8, and the second air outlet 6, precise control and guidance of air flow can be achieved. This design helps to optimize the air flow path, reduce air flow resistance and vortex, and improve ventilation efficiency.

[0040] In some embodiments, referring to Figure 6 and Figure 7 , the air duct component 2 includes a first fan assembly 9, a second fan assembly 10, and a volute 11, the volute 11 is provided with a third air outlet 12, a first channel 13, and a fourth air outlet 14 that are sequentially connected, the first fan assembly 9 and the second fan assembly 10 are both arranged in the first channel 13, the third air outlet 12 is provided with a second channel 15 and a third channel 16 side by side, the second channel 15 and the third channel 16 are both connected with the first channel 13, the fourth air outlet 14 is provided with a fourth channel 17 and a fifth channel 18 side by side, the fourth channel 17 and the fifth channel 18 are both connected with the first channel 13, the second ventilation channel 8 is connected with the fourth air outlet 14, the first fan assembly 9 and the second fan assembly 10 are both connected with the first ventilation channel 7, and the third air outlet 12 is connected with the first air outlet 4.

[0041] By arranging the second channel 15 and the third channel 16 side by side, and the fourth channel 17 and the fifth channel 18, this structure provides multiple choices of air flow paths. This design allows flexible adjustment of air flow according to actual needs, meeting different ventilation requirements. The first fan assembly 9 and the second fan assembly 10 are both arranged in the first channel 13, which can further adjust the intensity and direction of air flow by controlling their speed and direction, achieving more precise air flow control.

[0042] Among them, the first fan assembly 9 includes a driving member 19 and a centrifugal fan blade 20, and the driving member 19 and the centrifugal fan blade 20 are in transmission connection.

[0043] The driving member 19 can be an electric motor or other types of motor, with appropriate power and speed specifications chosen according to actual needs. The driving member 19 is usually mounted on a bracket inside the volute 11, ensuring its stability and ease of maintenance. The centrifugal fan blade 20 is made of high-strength lightweight materials such as aluminum alloy or engineering plastics, aiming to improve efficiency while reducing overall weight. The centrifugal fan blade 20 is located in front of the driving member 19 (relative to the direction of airflow) and is connected to the driving member 19 directly or indirectly through a shaft, ensuring good synchronization between the two.

[0044] When the driving member 19 starts, the rotational motion it generates is transmitted to the centrifugal fan blade 20 through a selected transmission method, causing the centrifugal fan blade 20 to rotate at high speed. Due to the centrifugal force, air is sucked into the central area of the centrifugal fan blade 20 and discharged radially outward, forming a powerful airflow.

[0045] It should be noted that the first fan assembly 9 and the second fan assembly 10 have similar structures, and this embodiment will not be described in more detail.

[0046] In some embodiments, the baffle includes a first baffle 21 rotatably disposed in the volute 11 to connect or disconnect the first passage 13 and the second passage 15 when the first baffle 21 is opened or closed.

[0047] By rotating the first baffle 21, the user can easily switch between the open and closed states, thereby controlling the connectivity between the first passage 13 and the second passage 15. This flexibility enables the system to quickly adjust according to different working needs. When both the first passage 13 and the second passage 15 need to be utilized simultaneously, the opening of the first baffle 21 can ensure smooth flow of fluids or gases, reducing resistance and thus improving the efficiency of the entire system. Conversely, in cases where the two passages do not need to be connected, closing the first baffle 21 can avoid unnecessary energy loss, further optimizing system performance.

[0048] In some embodiments, the baffle further includes a second baffle 22 rotatably disposed in the volute 11 to connect or disconnect the fourth passage 17 and the first passage 13 when the second baffle 22 is opened or closed.

[0049] When the second baffle 22 is in the open position, it directly connects the fourth passage 17 and the first passage 13, allowing airflow to flow freely between the two passages. This configuration is suitable for situations where the ventilation volume of a certain area needs to be enhanced. Conversely, when the second baffle 22 is closed, it completely blocks the airflow between the fourth passage 17 and the first passage 13, effectively isolating the two spaces. This helps to maintain the environmental conditions of a particular area unchanged in cases where airflow exchange is not needed.

[0050] In some embodiments, the baffle further comprises: a third baffle 23 and a fourth baffle 24, which are respectively arranged on both sides of the same end of the volute 11 and rotatably arranged outside the volute 11, so as to disconnect the first ventilation passage 7 and the second ventilation passage 8 or connect the first ventilation passage 7 and the second ventilation passage 8 when the third baffle 23 and the fourth baffle 24 are opened or closed.

[0051] When the third baffle 23 and the fourth baffle 24 are in the open position, the first ventilation passage 7 and the second ventilation passage 8 are disconnected, preventing air flow between the two passages. This configuration is suitable for situations where different areas of air flow need to be isolated. Conversely, when the third baffle 23 or the fourth baffle 24 is closed, it allows air flow between the first ventilation passage 7 and the second ventilation passage 8 to flow freely, effectively connecting the two spaces. This helps to maintain consistent environmental conditions in specific areas when air flow exchange is required.

[0052] In some embodiments, the third baffle 23 and the fourth baffle 24 are both driven to rotate by a motor to achieve opening and closing.

[0053] In some embodiments, the air duct component 2 further comprises: a first volute tongue movement mechanism 25 arranged in the first passage 13 to connect the first fan assembly 9 and the third passage 16 when rotated to a first position, or to connect the first fan assembly 9 and the first passage 13 when rotated to a second position.

[0054] In the initial state, the volute body of the first volute tongue movement mechanism 25 can be in a default position, for example, in communication with the first passage 13. When it is necessary to adjust the communication state of the air duct, the driving device is started to drive the volute body to rotate around its rotation axis.

[0055] When the volute body is rotated to the first position, its shape and position change, allowing the air flow generated by the first fan assembly 9 to smoothly enter the third passage 16, thereby achieving communication between the first fan assembly 9 and the third passage 16. At this time, the communication between the first passage 13 and the first fan assembly 9 can be partially or completely blocked, depending on the shape and rotation angle of the volute body.

[0056] When the volute body is rotated to the second position, its shape and position return to the state of communication with the first passage 13, allowing the air flow generated by the first fan assembly 9 to smoothly enter the first passage 13. At this time, the communication between the first fan assembly 9 and the third passage 16 is blocked, and the air flow is guided into the first passage 13.

[0057] By precisely controlling the movement position of the volute tongue, the flow field distribution of the air duct can be optimized, and the air flow resistance and energy loss can be reduced. When the first volute tongue movement mechanism 25 is rotated to the first position, it can be ensured that the air flow generated by the first fan assembly 9 enters the third channel 16 directly and efficiently; and when it is rotated to the second position, it can be ensured that the air flow enters the first channel 13 smoothly. Such precise control helps to improve the energy efficiency of the entire system.

[0058] In some embodiments, the air duct component 2 further comprises a second volute tongue movement mechanism 26 arranged in the first channel 13 to communicate the second fan assembly 10 and the fifth channel 18 when rotated to the third position, or to communicate the second fan assembly 10 and the first channel 13 when rotated to the fourth position.

[0059] In the initial state, the volute tongue body of the second volute tongue movement mechanism 26 can be located at a default position, for example, a position in communication with the first channel 13. When it is necessary to adjust the communication state of the air duct, the driving device is started to rotate the volute tongue body around its rotation axis.

[0060] When the volute tongue body is rotated to the third position, its shape and position change, so that the air flow generated by the second fan assembly 10 can enter the fifth channel 18 smoothly, thereby realizing the communication between the second fan assembly 10 and the fifth channel 18. At this time, the communication between the first channel 13 and the second fan assembly 10 can be partially or completely blocked, depending on the shape and rotation angle of the volute tongue body.

[0061] When the volute tongue body is rotated to the fourth position, its shape and position return to the state of communication with the first channel 13, so that the air flow generated by the second fan assembly 10 can enter the first channel 13 smoothly. At this time, the communication between the second fan assembly 10 and the fifth channel 18 is blocked, and the air flow is guided into the first channel 13.

[0062] By precisely controlling the movement position of the volute tongue, the flow field distribution of the air duct can be optimized, and the air flow resistance and energy loss can be reduced. When the second volute tongue movement mechanism 26 is rotated to the third position, it can be ensured that the air flow generated by the second fan assembly 10 enters the fifth channel 18 directly and efficiently; and when it is rotated to the fourth position, it can be ensured that the air flow enters the first channel 13 smoothly. Such precise control helps to improve the energy efficiency of the entire system.

[0063] It is worth noting that the first volute tongue movement mechanism 25 and the second volute tongue movement mechanism 26 in the present embodiment borrow mature mechanisms and are not described in detail.

[0064] In some embodiments, please refer to Figure 1 and Figure 8Further comprising: a top cover component 27 disposed on the first air outlet 4, the top cover component 27 is provided with a movement baffle 28 and a top cover piece 29, the top cover piece 29 is provided with a first top cover opening 30, a second top cover opening 31 and a third top cover opening 32, the first top cover opening 30 and the second top cover opening 31 are respectively disposed on both sides of the third top cover opening 32, the movement baffle 28 is slidingly disposed on the top cover piece 29 to close the first top cover opening 30 and the second top cover opening 31 when sliding onto the first top cover opening 30 and the second top cover opening 31, and to close the third top cover opening 32 when sliding onto the third top cover opening 32.

[0065] The first top cover opening 30, the second top cover opening 31 and the third top cover opening 32 on the top cover component 27 provide multiple ventilation modes for the air duct component 2. By sliding the movement baffle 28, specific top cover openings can be flexibly opened or closed, thereby achieving precise control of the ventilation direction and flow. This design enables the air duct component 2 to adapt to different ventilation needs and environmental conditions.

[0066] Further, the third top cover opening 32 is provided corresponding to the third air outlet 12, the first top cover opening 30 and the second top cover opening 31 are respectively provided corresponding to the gap channels between the volute 11 and the panel component 1, and the movement baffle 28 comprises: a first movement baffle 33 and a second movement baffle 34.

[0067] When the first movement baffle 33 slides onto the first top cover opening 30 and the second movement baffle 34 slides onto the second top cover opening 31, the first top cover opening 30 and the second top cover opening 31 can be closed, at this time the third top cover opening 32 and the third air outlet 12 are opened, thereby realizing updraft.

[0068] When the first movement baffle 33 and the second movement baffle 34 slide onto the third top cover opening 32 and abut, the third top cover opening 32 can be closed, at this time the first top cover opening 30 and the second top cover opening 31 are opened, thereby realizing downdraft.

[0069] The sliding mechanism of the movement baffle 28 is simple and efficient, and different ventilation modes can be switched by sliding without complex mechanical structures. This design reduces the difficulty and cost of operation, while improving the reliability and durability of the equipment. At the same time, the first movement baffle 33 and the second movement baffle 34 slide onto the third top cover opening 32, which can effectively prevent dust accumulation in the third top cover opening 32.

[0070] In some embodiments, further comprising: an air outlet frame component 35 (as shown in Figure 1 The air outlet frame component 35 is disposed between the top cover component 27 and the air duct component 2.

[0071] The design of the air outlet frame component 35 increases the structural integrity of the system, ensures smooth and uniform airflow, and improves the stability and reliability of the system.

[0072] Further, the air outlet frame component 35 is provided with a damper 36 (as shown in Figure 9 and Figure 10 ). When air flows into the first air outlet 4 from the air outlet frame component 35, the damper 36 is in an open state. When air does not flow out of the first air outlet 4, the damper 36 is in a closed state, thereby effectively preventing dust accumulation in the third air outlet 12.

[0073] In some embodiments, referring to Figure 1 , it also includes a lower air outlet component 37 and a bottom plate component 38, the lower air outlet component 37 is arranged between the evaporator component 3 and the second air outlet 6, and the bottom plate component 38 is installed at the bottom of the panel component 1.

[0074] The arrangement of the lower air outlet component 37 ensures that the airflow can be effectively guided from the evaporator component 3 to the second air outlet 6. This design optimizes the airflow path and improves flow efficiency. Through the lower air outlet component 37, air can be more evenly distributed to every corner of the room, enhancing the air circulation effect. This helps to reduce temperature gradients and improve the uniformity of indoor temperature, thereby improving user comfort. The bottom plate component 38 is installed at the bottom of the panel component 1, providing stable support for the entire system. This design enhances the stability of the structure, reducing the risk of noise and damage caused by vibration or external forces.

[0075] The working process of the air conditioner of the present embodiment is as follows:

[0076] Referring to Figure 2 and Figure 3 , when the air conditioner is in cooling mode, the first baffle 21 is open, and the first channel 13 and the second channel 15 are connected. The first volute tongue movement mechanism 25 rotates to the first position, and the first fan assembly 9 and the third channel 16 are connected. The second baffle 22 is closed, and the fourth channel 17 and the first channel 13 are disconnected. The second volute tongue movement mechanism 26 rotates to the fourth position, and the second fan assembly 10 and the first channel 13 are connected. The movement baffle 28 slides to close the first top cover opening 30 and the second top cover opening 31 when it is open, and the third top cover opening 32 is open. The third baffle 23 and the fourth baffle 24 are closed, and the first ventilation channel 7 and the second ventilation channel 8 are connected. At this time, the first fan assembly 9 and the second fan assembly 10 are both open, the airflow flows into the lower air outlet component 37 from the second air outlet 6 and into the second ventilation channel 8, and then flows into the gap channel between the air duct component 2 and the panel component 1 after passing through the evaporator component 3. At this time, part of the airflow passes through the third channel 16 under the action of the first fan assembly 9, and finally blows out from the third top cover opening 32 through the air outlet frame component 35. Another part of the airflow passes through the first channel 13 and the second channel 15 under the action of the second fan assembly 10, and finally blows out from the third top cover opening 32 and the first air outlet 4 through the air outlet frame component 35.

[0077] Please refer to Figure 4 and Figure 5 When the air conditioner is in the heating mode, the first shutter 21 is closed, the first passage 13 and the second passage 15 are disconnected. The first volute tongue movement mechanism 25 rotates to the second position, the first fan assembly 9 and the first passage 13 are communicated. The second shutter 22 is opened, the fourth passage 17 and the first passage 13 are communicated. The second volute tongue movement mechanism 26 rotates to the third position, the second fan assembly 10 and the fifth passage 18 are communicated. The movement shutter 28 slides to close the third top cover opening 32, the first top cover opening 30 and the second top cover opening 31 are opened. The third shutter 23 and the fourth shutter 24 are opened, the first ventilation passage 7 and the second ventilation passage 8 are disconnected. At this time, the first fan assembly 9 and the second fan assembly 10 are both opened, the air flow flows into the gap passage between the air duct component 2 and the panel component 1 through the first top cover opening 30 and the second top cover opening 31. At this time, part of the air flow flows out of the air duct component 2 through the first passage 13 and the fourth passage 17 under the action of the first fan assembly 9. Another part of the air flow flows out of the air duct component 2 through the fifth passage 18 under the action of the second fan assembly 10. The air flow flows out of the air duct component 2 through the third passage 16, the air outlet frame component 35, the evaporator component 3, the second ventilation passage 8, the lower air outlet component 37 and finally the second air outlet 6 in turn.
