Description

Technical Field

[0001] This disclosure relates to the field of household appliances, and more particularly to an air inlet baffle device, an indoor air conditioning unit, and an air conditioner. Background Technology

[0002] During air conditioner operation, airflow enters the unit through the air inlet, exchanges heat through the evaporator, and is then blown out through the air outlet, achieving heat exchange. The air inlet is located directly above the unit. To reduce dust entering the unit through the air inlet and affecting internal components, an air inlet baffle assembly is typically installed. When the air conditioner is not in use, the air inlet baffle assembly is closed to prevent dust from entering; when the air conditioner is running, the air inlet baffle assembly is open for ventilation.

[0003] In related technologies, air inlet damper assemblies include multiple dampers and a transmission component. The transmission component can fold the multiple dampers to open the air inlet of the air conditioner, or unfold the multiple dampers to close the air inlet of the air conditioner. However, traditional air inlet damper assemblies have poor operational reliability, and after long-term use, there is a problem that multiple dampers may not close tightly, resulting in poor dust prevention performance of the air conditioner. Summary of the Invention

The fitting structures are provided on the stop body, and one fitting structure corresponds to one latching protrusion. The fitting structure is provided with a snap-fit ​​groove adapted to the latching protrusion. When the stop body abuts against the transmission assembly, the latching protrusion engages with the snap-fit ​​groove.

[0010] In one possible implementation, multiple locking protrusions are distributed on the side edge of the transmission assembly. The fitting structure includes a support post and a fitting block. The support post is located on the side edge of the stop body, and the fitting block is connected to the side of the support post away from the stop body. The locking groove is located on the side of the fitting block facing the locking protrusion.

[0011] In one possible implementation, the transmission assembly includes a transmission member, a driving member, and at least two rotating members. The transmission member is sleeved outside the rotating members, and the driving member is used to drive the rotating members to rotate, thereby moving the transmission member.

[0012] The flexible baffle is located on the side of the transmission component near the air inlet.

[0013] In one possible implementation, the transmission assembly further includes a control element and a detection element. The detection element is used to detect the position of the flexible stop. Both the detection element and the drive element are communicatively connected to the control element. When the detection element detects that the flexible stop is located at the second end, the control element controls the drive element to stop operating.

[0014] In one possible implementation, there are three rotating members arranged in a right-angled triangle, and the transmission member includes a first segment and a second segment that are connected to each other, with the first segment and the second segment arranged perpendicularly.

[0015] In one possible implementation, the housing is provided with a support member, and the support member and the first side wall of the housing form a movable groove, and the collecting member is slidably connected to the movable groove.

[0016] In one possible implementation, the support member has a first sliding protrusion, the first sidewall has a second sliding protrusion, and the collecting member has a first sliding groove corresponding to the first sliding protrusion and a second sliding groove corresponding to the second sliding protrusion. The first sliding groove is located on the bottom wall of the collecting member, and the second sliding groove is located on the sidewall of the collecting member; and / or,

[0017] A limiting groove is provided on the second side wall of the housing, which is perpendicular to the first side wall, and the limiting groove extends along the sliding direction of the collecting component; when the collecting component is assembled on the housing, one end of the collecting component is accommodated in the limiting groove.

[0018] Secondly, this disclosure also provides an indoor air conditioning unit, including a body and an air inlet baffle device as described above, wherein the body is provided with an air inlet and the air inlet baffle device is located at the air inlet of the body.

[0019] Thirdly, this disclosure also provides an air conditioner, including an outdoor unit and an indoor unit as described above, wherein the indoor unit is connected to the outdoor unit.

[0020] According to the air inlet baffle device, air conditioner indoor unit, and air conditioner provided in this disclosure, the air inlet baffle device is used in ventilation equipment. The ventilation equipment includes a housing with an air inlet on the housing. The air inlet baffle includes: a transmission assembly disposed within the housing, the transmission assembly having a first end and a second end; a flexible baffle disposed on the side of the transmission assembly facing the air inlet; the flexible baffle has a closed state and an open state. In the closed state, the flexible baffle is located at the first end to close the air inlet; in the open state, the flexible baffle is located at the second end to expose the air inlet; and a collection member disposed within the housing, and the collection member is located below the second end, the collection member being used to collect dust on the flexible baffle. This technical solution improves the dustproof performance of ventilation equipment by optimizing the specific structure of the air inlet baffle device. Specifically, the air inlet damper device is configured as a combination of at least a transmission component, a flexible baffle, and a collection component. All three components are housed within the ventilation equipment's casing. The transmission component can drive the flexible baffle to move, so that when closed, the flexible baffle closes the air inlet, preventing dust from entering the casing and affecting other components. Alternatively, when open, the flexible baffle exposes the air inlet, allowing external airflow to enter the casing and improve ventilation performance. Simultaneously, when the flexible baffle is closed, external dust accumulates on the side away from the transmission component. When open, the accumulated dust falls into the collection component, collecting the dust entering the casing and further improving the dust removal efficiency of the air inlet damper device.

[0035] To make the objectives, technical solutions, and advantages of the embodiments of this disclosure clearer, the technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this disclosure. Based on the embodiments of this disclosure, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this disclosure.

[0036] See Figures 1 to 8 In a first aspect, the present disclosure provides an air inlet baffle device for a ventilation device. The ventilation device includes a housing 10 with an air inlet. The air inlet baffle includes a transmission assembly 100, a flexible baffle 200, and a collection component 300.

[0037] The transmission assembly 100 is disposed inside the housing 10, and the transmission assembly 100 has a first end 101 and a second end 102;

[0038] A flexible baffle 200 is disposed on the side of the transmission assembly 100 facing the air inlet; the flexible baffle 200 has a closed state and an open state. In the closed state, the flexible baffle 200 is located at the first end 101 to close the air inlet; in the open state, the flexible baffle 200 is located at the second end 102 to expose the air inlet; and

[0039] The collector 300 is disposed inside the housing 10 and is located below the second end 102. The collector 300 is used to collect dust on the flexible baffle 200.

[0040] In this embodiment, the dustproof performance of the ventilation equipment is improved by optimizing the specific structure of the air inlet baffle device. Specifically, the air inlet baffle device is configured as a combination of at least a transmission component 100, a flexible baffle 200, and a collection component 300. The transmission component 100, the flexible baffle 200, and the collection component 300 are all disposed within the housing 10 of the ventilation equipment. The transmission component 100 can drive the flexible baffle 200 to move, so that when the flexible baffle 200 is in the closed state, it closes the air inlet to prevent dust from entering the housing 10 from the air inlet and affecting other components inside the housing 10; or when the flexible baffle 200 is in the open state, it exposes the air inlet, allowing external airflow to enter the housing 10 from the air inlet, thereby improving the ventilation performance of the ventilation equipment. Meanwhile, when the flexible baffle 200 is in the closed state, external dust accumulates on the side of the flexible baffle 200 away from the transmission component 100; while when the flexible baffle 200 is in the open state, the dust accumulated on the flexible baffle 200 falls into the collecting member 300, realizing the collection and treatment of dust entering the housing 10, and further improving the dust removal effect of the air inlet baffle device. For example, but not limited to, the ventilation equipment is an air conditioner.

[0041] In one example, the collector 300 is a box structure with one open end facing the transmission assembly 100. After a period of time, the collector 300 is removed, the dust inside is disposed of, and then the collector 300 is washed and dried for reuse. This helps to reduce the operating cost of the air intake baffle device.

[0042] In one example, the flexible stop 200 is made of a flexible material, possessing both rigidity and flexibility. For example, but not limited to, the flexible stop 200 is made of materials such as polymer resin, polymer restraint, plastic film, asphalt waterproofing material, or waterproof membrane.

[0043] See Figure 4 and Figure 5In one possible implementation, the transmission assembly 100 is provided with a plurality of latching protrusions 103, and the flexible stop 200 includes a stop body 210 and a plurality of fitting structures 220. The fitting structures 220 are provided on the stop body 210, and one fitting structure 220 corresponds to one latching protrusion 103. The fitting structure 220 is provided with a snap-fit ​​groove 201 adapted to the latching protrusion 103. When the stop body 210 abuts against the transmission assembly 100, the latching protrusion 103 snaps into the snap-fit ​​groove 201.

[0044] In this embodiment, the specific structures of the transmission assembly 100 and the flexible stop 200 are configured to optimize the connection method between the flexible stop 200 and the transmission assembly 100. Specifically, the flexible stop 200 is configured as a combined component including at least a stop body 210 and multiple interlocking structures 220. At the same time, multiple locking protrusions 103 that cooperate with the multiple interlocking structures 220 are configured on the transmission assembly 100. In this way, the connection and fastening between the flexible stop 200 and the transmission assembly 100 are achieved through the interlocking of the interlocking structures 220 and the locking protrusions 103.

[0045] Furthermore, the fitting structure 220 is provided with a snap-fit ​​groove 201, and the snap-fit ​​protrusion 103 is snapped into the snap-fit ​​groove 201 to be connected and fastened to the fitting structure 220. The snap-fit ​​protrusion 103 should be interference-fitted into the snap-fit ​​groove 201 to ensure that the snap-fit ​​protrusion 103 does not detach from the snap-fit ​​groove 201.

[0046] In one example, the flexible body is a plate-like structure with a certain degree of flexibility. The fitting structure 220 is made of a rigid material to improve the connection and tightness between the flexible stop 200 and the transmission assembly 100. The snap-fit ​​groove 201 is a semi-cylindrical groove with more than half of its length, and the snap-fit ​​protrusion 103 is a columnar structure.

[0047] See Figure 4 and Figure 5 In one possible implementation, multiple latching protrusions 103 are distributed on the side edge of the transmission assembly 100. The fitting structure 220 includes a support post 221 and a fitting block 222. The support post 221 is located on the side edge of the stop body 210. The fitting block 222 is connected to the side of the support post 221 away from the stop body 210. The latching groove 201 is located on the side of the fitting block 222 facing the latching protrusions 103.

[0048] In this embodiment, the placement of the protruding structure 103 and the specific structure of the fitting structure 220 are optimized to improve the connection stability between the protruding structure 103 and the fitting structure 220. Specifically, the fitting structure 220 is configured as a composite component including at least a support column 221 and a fitting block 222. The support column 221 is connected to the stop body 210 to provide support and a certain lateral distance to the fitting block 222.

[0049] In one example, the interlocking block 222 is a triangular block structure, and the snap-fit ​​groove 201 is disposed on one side of the interlocking block 222.

[0050] See Figures 1 to 3 In one possible implementation, the transmission assembly 100 includes a transmission member 110, a driving member 120 and at least two rotating members 130. The transmission member 110 is sleeved on the rotating member 130, and the driving member 120 is used to drive the rotating member 130 to rotate so as to move the transmission member 110.

[0051] The flexible baffle 200 is located on the side of the transmission component 110 near the air inlet.

[0052] In this embodiment, the specific structure of the transmission assembly 100 is optimized. Specifically, the transmission assembly 100 is configured as a combination component including at least a transmission member 110, a driving member 120, and at least two rotating members 130. The driving member 120 drives the rotating members 130 to rotate, thereby moving the transmission member 110 sleeved on the rotating members 130, which in turn moves the flexible stop member 200 connected to the transmission member 110, thereby closing or opening the air inlet and realizing the ventilation operation of the air conditioner.

[0053] In one example, the transmission component 110 is a conveyor chain, the rotating component 130 is a gear, the conveyor chain is sleeved on the outside of the gear, and the driving component 120 is a motor or cylinder rotary motor. Thus, when the driving component 120 drives the gear to rotate, the gear will drive the conveyor chain to rotate, thereby driving the flexible stop 200 connected to the conveyor chain to move, realizing the closing or opening of the air inlet.

[0054] See Figure 1 In one possible implementation, the transmission assembly 100 further includes a control element 140 and a detection element 150. The detection element 150 is used to detect the position of the flexible stop 200. The detection element 150 and the drive element 120 are both communicatively connected to the control element 140. When the detection element 150 detects that the flexible stop 200 is located at the second end 102, the control element 140 controls the drive element 120 to stop operating.

[0055] In this embodiment, the specific structure of the transmission assembly 100 is optimized. Specifically, the transmission assembly 100 is configured as a combination of at least a transmission member 110, a drive member 120, at least two rotating members 130, a control member 140, and a detection member 150. The control member 140 is disposed within the housing 10, and the detection member 150 is disposed on the second end 102 of the transmission member 110. When the flexible stop member 200 moves to the second end 102 and abuts against the detection member 150, the detection member 150 detects pressure information and transmits the pressure information to the control member 140. The control member 140 receives and processes the pressure information and simultaneously controls the drive member 120 to stop operating, so as to prevent the flexible stop member 200 from continuing to move.

[0056] In one example, the detection element 150 is a pressure sensor. The detection element 150 includes a control chip and a signal receiver. The signal receiver is communicatively connected to the control chip, and the pressure sensor is communicatively connected to the signal receiver. In this way, after the pressure sensor detects the flexible stop 200, it transmits the information to the signal receiver, which then transmits the received information to the control chip. The control chip controls the movement direction and speed of the drive element 120 according to the received information, and the control chip can also control whether the drive element 120 operates according to the received information.

[0057] See Figures 1 to 3 In one possible implementation, there are three rotating members 130, which are distributed in a right-angled triangle shape. The transmission member 110 includes a first segment 111 and a second segment 112 that are connected, and the first segment 111 and the second segment 112 are arranged perpendicularly.

[0058] In this embodiment, to reduce costs, three rotating members 130 are provided. Since the transmission member 110 is sleeved on the outside of the three rotating members 130, the transmission member 110 has a specific shape due to the arrangement of the three rotating members 130. The three rotating members 130 are distributed at right angles, so that the transmission member 110 forms an inverted L-shaped structure, which includes a first horizontal segment 111 and a second vertical segment 112.

[0059] When closed, the flexible baffle 200 is located on the first horizontal section 111. At this time, the flexible baffle 200 can completely close the air inlet to prevent external dust from entering the housing 10. When open, the flexible baffle 200 is located on the second vertical section 112. At this time, the flexible baffle 200 can fully expose the air inlet, making the air inlet area larger. Under the same power, the air conditioner can achieve a larger air volume and save more energy.

[0060] See Figures 6 to 8In one possible implementation, the housing 10 is provided with a support member 20, and the support member 20 and the first side wall 11 of the housing 10 form a movable groove, and the collecting member 300 is slidably connected to the movable groove.

[0061] In this embodiment, the connection method between the collector 300 and the housing 10 is optimized. Specifically, a horizontally arranged support member 20 is provided inside the housing 10 to form a movable groove with the inherent structure of the housing 10, allowing the collector 300 to slide and connect, thus facilitating the assembly and removal of the collector 300. For example, but not limited to, the support member 20 is a support plate.

[0062] See Figures 6 to 8 In one possible implementation, the support member 20 is provided with a first sliding protrusion 21, the first side wall 11 is provided with a second sliding protrusion 1101, and the collecting member 300 is provided with a first sliding groove 301 corresponding to the first sliding protrusion 21 and a second sliding groove 302 corresponding to the second sliding protrusion 1101. The first sliding groove 301 is located on the bottom wall of the collecting member 300, and the second sliding groove is located on the side wall of the collecting member 300.

[0063] In this embodiment, the specific structure of the collecting component 300 is configured to optimize the connection between the collecting component 300 and the housing 10. Specifically, sliding protrusion structures are provided on the support member 20 and the first side wall 11, while a sliding groove structure is provided on the collecting component 300, so that the collecting component 300 and the housing 10 can be slidably connected through the cooperation of the sliding protrusion structure and the sliding groove structure.

[0064] In one example, two first sliding grooves 301 and multiple first sliding protrusions 21 are provided. Each first sliding groove 301 has at least two first sliding protrusions 21 spaced apart, thereby improving the connection stability and sliding smoothness between the collector 300 and the support 20. Two second sliding grooves 302 and multiple second sliding protrusions 1101 are provided. Each second sliding groove 302 has at least two second sliding protrusions 1101 spaced apart, thereby improving the connection stability and sliding smoothness between the collector 300 and the first sidewall 11.

[0065] See Figure 7 and Figure 8 In one possible implementation, a limiting groove 1201 is provided on the second side wall 12 of the housing 10, which is perpendicular to the first side wall 11. The limiting groove 1201 extends along the sliding direction of the collecting member 300. When the collecting member 300 is assembled on the housing 10, one end of the collecting member 300 is accommodated in the limiting groove 1201.

[0066] In this embodiment, the specific structure of the housing 10 is designed to improve the connection and tightness between the collecting member 300 and the housing 10. Specifically, a limiting groove 1201 is provided on the housing 10, which is recessed in the second side wall 12. On the one hand, the bottom of the limiting groove 1201 can provide a certain supporting force to the support member 20, thereby improving the connection stability between the support member 20 and the housing 10; on the other hand, when the limiting groove 1201 is closed, it can accommodate part of the collecting member 300, thereby improving the connection stability between the collecting member 300 and the housing 10.

[0067] Secondly, this disclosure also provides an indoor air conditioning unit, including a body and an air inlet baffle device as described above.
