Description

Technical Field

[0001] This application relates to the field of air conditioner technology, such as a baffle and an indoor air conditioner unit. Background Technology

[0002] With the improvement of living standards, air conditioners have become an indispensable household appliance for improving the quality of life and are widely used. Air conditioner indoor units installed on the upper wall or ceiling of a room often have side-discharge airflow. When heating, the density of hot air is low, and the side-discharge airflow causes the hot air to rise, failing to reach users in the lower part of the room. This results in uneven temperature distribution within the room, causing the upper part to be hot and the lower part cold, which is particularly unpleasant for users who are prone to cold hands and feet.

[0003] In related technologies, to enable the switching of airflow direction in an air conditioning indoor unit, an air conditioning indoor unit and an air conditioner are disclosed. The air conditioning indoor unit includes a housing and a rotating air duct assembly. The housing has a first air outlet and a second air outlet; the rotating air duct assembly is disposed within the housing and is rotatable relative to the housing to allow the air conditioning indoor unit to switch between a first air outlet mode and a second air outlet mode. When the air conditioning indoor unit is in the first air outlet mode, air from outside the housing enters through the first air outlet and exits through the second air outlet after flowing through the rotating air duct assembly. When the air conditioning indoor unit is in the second air outlet mode, air from outside the housing enters through the second air outlet and exits through the first air outlet after flowing through the rotating air duct assembly. The housing includes a fixed housing portion and a movable housing portion. The movable housing portion can move away from the fixed housing portion, and the movement stroke allows the rotating air duct assembly to rotate freely within the housing. The rotating air duct assembly includes a centrifugal impeller assembly or an axial flow impeller assembly.

[0004] In the process of implementing the embodiments of this disclosure, at least the following problems were found in the related art:

[0005] During the rotation of the centrifugal fan assembly, a certain gap needs to be reserved to avoid interference between the centrifugal fan assembly and adjacent components, which could cause malfunctions in the indoor unit of the air conditioner. However, during the air outlet process of the indoor unit, airflow can easily become turbulent and enter the gap, causing air leakage, which in turn leads to low air volume, high noise, and affects the user experience. Summary of the Invention

[0006] To provide a basic understanding of some aspects of the disclosed embodiments, a brief summary is given below. This summary is not intended as a general commentary, nor is it intended to identify key / important components or describe the scope of protection of these embodiments, but rather as a prelude to the detailed description that follows.

[0014] In some alternative embodiments, the housing includes a first bottom wall, a second bottom wall, and a first side wall. The first bottom wall has a downdraft opening, and the first side wall has a side vent opening. The volute rotates to allow the indoor unit of the air conditioner to switch between a first air outlet mode and a second air outlet mode. In the first air outlet mode, air is drawn in through the downdraft opening and discharged through the side vent opening. In the second air outlet mode, air is drawn in through the side vent opening and discharged through the downdraft opening.

[0015] In some alternative embodiments, the indoor unit of the air conditioner also includes a water collection tray located on the first bottom wall, and when the indoor unit of the air conditioner is running in the first air outlet mode, the bottom of the baffle body overlaps the water collection tray.

[0016] In some alternative embodiments, the indoor unit of the air conditioner also includes a seal located on the second bottom wall, and when the indoor unit of the air conditioner is operating in the first air outlet mode, the top of the sealing partition overlaps the seal.

The accompanying drawings are for illustrative purposes only and are not intended to limit the embodiments of this disclosure.

[0037] It should be noted that, unless otherwise specified, the embodiments and features described in the present disclosure can be combined with each other.

[0038] Combination Figure 1-6 As shown, this disclosure provides a baffle and an indoor air conditioning unit. The indoor air conditioning unit includes a wall-mounted unit and a ducted unit. This application will use a ducted unit as an example for explanation.

[0039] Traditional ducted air conditioners can achieve two air outlet modes by adding a rotating duct assembly: one with air intake at the bottom and air outlet at the side, and the other with air intake at the side and air outlet at the bottom. The housing includes a fixed housing and a movable housing. The movable housing can move away from the fixed housing, and its movement allows the rotating duct assembly to rotate freely within the housing. The rotating duct assembly includes a centrifugal impeller assembly. While ducted air conditioners in related technologies can achieve air outlet switching, the rotation of the rotating duct assembly requires clearance, leading to turbulent airflow within the ducted air conditioner and severely affecting the airflow volume. Therefore, although there are conceptual designs for ducted air conditioners that can achieve reversible airflow, none have been applied to actual products.

[0040] The baffle 4 provided in this embodiment is used in a reversible air supply air conditioner indoor unit, which includes a ducted air conditioner. This embodiment also provides an air conditioner indoor unit including a baffle 4. The baffle 4 includes a baffle body 42 and flanges 43. The baffle body 42 is an arc-shaped air guide plate, installed inside the housing 1 of the air conditioner indoor unit, and used to guide the airflow direction; there are two flanges 43, located on both sides of the baffle body 42 along its length, perpendicular to the baffle body 42, and used to approach adjacent components to cut off the airflow on both sides of the baffle body 42.

[0041] Specifically, baffle 4 is installed inside the duct unit. Baffle 4 isolates the inlet airflow from the outlet airflow and guides the outlet airflow direction. Baffle 4 has flanges 43 on both sides. The flanges 43 are perpendicular to the baffle body 42 and parallel to the side wall of the duct unit. The flanges 43 are used to close to adjacent components to cut off the airflow on both sides of the baffle body 42, completely separating the inlet airflow from the outlet airflow and avoiding airflow turbulence problems.

[0042] Optionally, the baffle body 42 includes an outer wall surface and an inner wall surface. The outer wall surface is used to guide the airflow direction; the inner wall surface is arranged opposite to the outer wall surface, and one or more reinforcing ribs are provided on the inner wall surface. In this way, it not only plays a role in guiding the airflow, but also improves the deformation resistance of the baffle body 42 by adding reinforcing ribs, avoiding the problem of excessively long baffles 4 deforming and creating gaps with adjacent components in the duct unit, thus affecting the airflow volume.

[0043] Optionally, the flange 43 is an arc-shaped panel with a groove. The opening of the groove faces the extension direction of the baffle body 42, and one or more ribs are provided in the groove. By setting the flange 43, the baffle 4 can achieve a large-area seal with its adjacent components. The groove reduces the weight of the baffle 4, preventing deformation on both sides of the baffle 4 due to excessive weight of the flange 43. At the same time, the ribs in the groove can strengthen the flange 43 and prevent the arc-shaped panel from warping, thus avoiding poor sealing between the flange 43 and adjacent components.

[0044] Optionally, the flange 43 includes a flange body 431 and a rib. The flange body 431 is connected to the baffle body 42; the rib includes a first rib 432, which is vertically fixed to the outer edge of the flange body 431, and the curvature of the first rib 432 is the same as the curvature of the blocking surface 311. The first rib 432 and the flange body 431 together enclose a groove with an opening facing the connecting plate 3. This not only reduces the weight of the flange 43, but also increases the contact area between the flange 43 and the blocking surface 311, improving the sealing performance of the movement gap.

[0045] Optionally, the rib also includes a second rib 433, which is located within the groove enclosed by the first rib 432, the flange body 431, and the baffle body 42. There are multiple second ribs 433. These multiple second ribs 433 strengthen the flange 43 and improve the stability of the baffle 4 during rotation.

[0046] Optionally, the indoor unit of the air conditioner also includes a pivot shaft 41, which is pivotally connected to the baffle body 42. The pivot shaft 41 rotates circumferentially to drive the baffle body 42 to rotate. The baffle body 42 is rotatably mounted in the indoor unit of the air conditioner via the pivot shaft 41. In this way, by rotating the baffle 42, different air outlet modes can be satisfied, ensuring the air volume in different air outlet modes, so that the intake airflow and the exhaust airflow do not interfere with each other, and avoid airflow turbulence.

[0047] Optionally, the indoor unit of the air conditioner also includes a connecting plate 3 and a sealing partition 2. The connecting plate 3 is fixed inside the housing 1; the sealing partition 2 is rotatably connected to the connecting plate 3 and is used to fix the volute 5; wherein, the baffle 4 is pivotally connected to the sealing partition 2 through a pivot shaft 41, and when the baffle 4 rotates to a preset angle, the flange 43 overlaps the connecting plate 3 to seal the movement gap between the baffle 4 and the connecting plate 3.

[0048] Specifically, a connecting plate 3 is fixed inside the duct unit, and a sealing partition 2 is rotatably connected to the connecting plate 3. The volute 5 is fixed on the sealing partition 2. Thus, the rotation of the sealing partition 2 can drive the volute 5 to rotate, thereby directing the airflow at the outlet of the volute 5 in a specific direction. During the airflow switching process of the duct unit, a movement gap is left between the baffle 4 and the connecting plate 3 to avoid movement interference. When the duct unit is in the airflow outlet state, rotating the baffle 4 allows the flange 43 of the baffle 4 to overlap and fit against the blocking surface 311, sealing the movement gap and separating the airflow on the inlet side and the airflow on the outlet side of the volute 5, allowing them to communicate only through the outlet of the volute 5, thus avoiding the problem of airflow turbulence.

[0049] Optionally, there are multiple volutes 5, and the sealing partition 2 has multiple clearance notches, with each volute 5 corresponding to and snapped onto the clearance notch. The sealing partition 2 includes a first partition and a second partition. The first partition has clearance notches, and the air outlet of the volute 5 is snapped onto the clearance notch; the second partition is vertically fixedly connected to the first partition, and the second partition is rotatably connected to the connecting plate 3.

[0050] Specifically, there are two connecting plates 3, which are fixed to both sides of the base plate and close to the side plates. There are also two second partitions on the sealing partition 2, with the first partition fixed between the two second partitions. This ensures a more reliable connection and more accurate positioning between the first and second partitions. The sealing partition 2 not only provides load-bearing and support for the multiple volutes 5, preventing deformation of the duct unit, but also drives the volutes 5 to rotate, allowing the duct unit to switch air outlets without the need for additional duct switching components. The two connecting plates 3 are located on both sides of the two second partitions, with the connecting plates 3 on the same side rotatably connected to the second partitions. This avoids turbulent airflow on both sides of the volutes 5.

[0051] Optionally, the indoor unit of the air conditioner also includes a power component, comprising a driving gear 6 and a driven gear 7 for meshing transmission. The driving gear 6 is rotatably connected to the connecting plate 3, and the driven gear 7 passes through the connecting plate 3 and is fixedly connected to the second partition. The rotation of the driving gear 6 causes the driven gear 7 to drive the sealing partition 2 and the volute 5 to rotate. There are multiple volutes 5, which are fixed to the first partition. The impellers inside the multiple volutes 5 are connected by a rotating shaft 8, which is rotatably mounted inside the duct unit. The rotation of the rotating shaft 8 drives the impellers to rotate.

[0052] Optionally, the power assembly also includes a drive unit 9, which is mounted on the connecting plate 3. The drive output end of the drive unit 9 is connected to the connecting plate 3 to drive the drive gear 6 to rotate, which in turn drives the sealing partition 2 and the volute 5 to rotate via the driven gear 7.

[0053] Optionally, the side wall of the sealing partition 2 is provided with a sealing strip, and the side wall of the connecting plate 3 is provided with a raised rib 32. In the side air outlet state of the duct unit, the sealing strip and the raised rib 32 cooperate to seal the gap between the sealing partition 2 and the connecting plate 3. Specifically, when the sealing partition 2 and the volute 5 switch and rotate between different air outlet modes, the sealing strip and the raised rib 32 do not cooperate, and a movement space is formed between the sealing partition 2 and the connecting plate 3 to avoid movement interference between them. When switching to a specific air outlet mode, the sealing strip overlaps the raised rib 32, thereby sealing the gap used to form the movement space and thus preventing air leakage in the duct.

[0054] Optionally, the first partition may be made of aluminum alloy, and the second partition may be made of ABS plastic; and / or, the baffle 4 may be made of ABS plastic. The first partition is used to fix the volute 5, therefore, it is made of aluminum alloy, which is durable and easy to pressure process. Furthermore, since the first partition inside the duct unit is relatively long, using a high-rigidity aluminum alloy first partition can avoid deformation problems. Compared to plastic, aluminum alloy has a lower coefficient of thermal expansion, avoiding movement interference or gaps between the sealing partition 2 and the connecting plate 3 due to thermal expansion or contraction. The second partition and baffle 4 are made of plastic, thus providing stronger impact resistance and wear resistance, thereby improving the service life of the components.

[0055] Optionally, d = 0.5L*k; where d is the thickness of the flange 43, L is the length of the baffle body 42, and k is the coefficient of thermal expansion and contraction of the baffle 4. It is understandable that the longer the baffle body 42, the greater the amount of thermal expansion and contraction, thus having a greater impact on the movement gap between the baffle 4 and the connecting plate 3. This formula allows the duct air conditioner to adjust the thickness of the flange 43 according to the length of the baffle body 42 and the coefficient of thermal expansion and contraction of the baffle 4 material, to meet the needs of different duct air conditioner models.

[0056] Optionally, the housing 1 includes a first bottom wall, a second bottom wall, and a first side wall. The first bottom wall has a downdraft opening 12, and the first side wall has a side vent opening 11. The volute 5 rotates to switch the indoor unit of the air conditioner between a first air outlet mode and a second air outlet mode. In the first air outlet mode, air is drawn in through the downdraft opening 12 and discharged through the side vent opening 11. In the second air outlet mode, air is drawn in through the side vent opening 11 and discharged through the downdraft opening 12.

[0057] Specifically, when the indoor temperature is too high, the cooling mode is activated, corresponding to the first air outlet mode. The volute 5 rotates so that its air outlet aligns with the side air outlet 11 of the casing 1, allowing air to enter through the lower air outlet 12 of the duct unit and exit through the side air outlet 11. The duct unit's air outlet direction is lateral, ensuring that cold air descends from top to bottom during cooling, resulting in more even cooling and air distribution. When the indoor temperature is too low, the heating mode is activated, corresponding to the second air outlet mode. The volute 5 rotates so that its air outlet aligns with the lower air outlet 12 of the casing 1, allowing air to enter through the side air outlet 11 and exit through the lower air outlet 12. The duct unit's air outlet direction is downward. Since hot air is lighter and tends to float at the top of the room, this downward air outlet direction effectively delivers hot air to the user's area, improving the comfort of the space.

[0058] Optionally, the indoor unit of the air conditioner also includes a water collection tray located on the first bottom wall. When the indoor unit of the air conditioner is running in the first air outlet mode, the bottom of the baffle body 42 overlaps the water collection tray.

[0059] When heating, the ducted air conditioner operates in the second air outlet mode. The sealing baffle 2 rotates so that the air outlet of the volute 5 corresponds to the lower air outlet 12, and the baffle 4 rotates to abut against the first bottom wall. When cooling, the ducted air conditioner operates in the first air outlet mode. The sealing baffle 2 rotates in the opposite direction so that the air outlet of the volute 5 corresponds to the side air outlet 11, and the baffle 4 rotates so that its bottom abuts against the water receiving tray, and the flange 43 abuts against the boss 31, thereby sealing the movement gap around the baffle 4, separating the air inlet and outlet airflow, and avoiding the problem of airflow turbulence.

[0060] Optionally, the indoor unit of the air conditioner also includes a sealing strip located on the second bottom wall. When the indoor unit is operating in the first air outlet mode, the top of the sealing partition 2 overlaps with the sealing strip. The second bottom wall is set opposite to the first bottom wall. When the side air outlet 11 is in the air outlet state, the top of the sealing partition 2 overlaps with the sealing strip, and the bottom of the baffle body 42, which is pivotally connected to the sealing partition 2, abuts against the water receiving tray. The flanges 43 on both sides of the baffle 4 abut against the boss 31, thereby dividing the inside of the air duct unit into an air inlet area and an air outlet area. The air inlet area and the air outlet area are connected only through the air outlet of the volute 5. In this way, the problem of turbulent airflow inside the indoor unit of the air conditioner can be avoided, the air inlet airflow and the air outlet airflow are separated, the air volume is increased, and the wind noise is reduced.
