Description

Technical Field

[0001] The present invention relates to the technical field of air conditioner accessories, and in particular to a dust collecting device for air outlet blades of a central air conditioner. Background Art

[0002] The central air-conditioning system consists of one or more cold and heat source systems and multiple air conditioning systems. It uses the principle of liquid vaporization refrigeration to provide the required cooling capacity for the air conditioning system to offset the heat load of the indoor environment; the heating system provides the required heat for the air conditioning system to offset the cold and warm loads of the indoor environment, and the air outlet blades guide the air blown out by the air conditioner.

[0003] A Chinese patent with announcement number CN116792813B discloses an air outlet blade of a central air conditioner. After a frame is squeezed by an extrusion rod, the extrusion rod moves inside the frame, and the extrusion rod contacts the inclined surface of a flip plate. The flip plate is squeezed and rotates around a storage box. A gap appears between the flip plate and the storage box. Dust that falls inside the storage box can reach the outside through the gap between the flip plate and the storage box. A gap is provided between the flip plate and the horizontal plate for the flip plate to rotate, so that the flip plate will not be blocked by the horizontal plate during rotation, making it easier to discharge dust from the storage box.

[0004] The disadvantage is that the squeezing rod squeezes the inclined surface of the flip plate to make it rotate, and the rotation angle of the flip plate is limited, resulting in a smaller gap between the flip plate and the storage box, thereby affecting the dust discharge effect. Summary of the invention

[0040] One or more technical solutions provided in this application have at least the following technical effects or advantages:

[0041] Firstly, after the frame is squeezed by the first pressure rod, the first pressure rod moves inside the storage box, and the first pressure rod compresses the bottom plate, which is squeezed and becomes smaller, thereby forming a gap between the bottom plate and the storage box. The formation of this gap is not restricted by the transverse plate, which effectively solves the problem of the small gap between the flip plate and the storage box in the prior art, thereby increasing the gap for dust discharge and improving the dust discharge effect.

[0042] Secondly, by setting a second air hole and adding a membrane petal to allow air to enter the first air hole and exhaust the second air hole, the airflow discharged from the second air hole is guided to the inclined top surface of the bottom plate through an air guide pipe. As a result, when the bottom plate is deformed to produce a gap, the internal air is squeezed out to form an airflow that blows toward the inclined top surface, thereby assisting the dust to be discharged from the gap below, thereby improving the dust discharge effect.

[0043] Thirdly, a dust-proof film is arranged above the bottom plate, and one end of the dust-proof film is fixed to the middle part of the output end of the air duct, and a weight-increasing rod is arranged at the other end of the dust-proof film. Thus, when the gap is opened, the bottom end of the dust-proof film falls from the gap due to gravity, and the gap is opened for dust to be discharged. At the same time, when the airflow passes through the upper and lower sides of the dust-proof film, the dust-proof film vibrates to facilitate the shaking off of the dust. At the same time, the dust is discharged from the gap below with the assistance of the airflow, thereby improving the dust discharge effect.

[0044] Fourthly, by adding a first pull rope at both ends of the weight-increasing rod, adding a first fixed pulley, a slide groove, a sliding seat, a second fixed pulley, a first spring, etc. inside the storage box, and cooperating with the second pressure rod, when the storage box moves to the other side frame, the weight-increasing rod is pulled up by the pull rope and moved to the other end of the storage box. At the same time, the ups and downs of the two slide grooves are opposite, so that the weight-increasing rod can also be shaken when it moves with the sliding seat, thereby shaking off the dust to the upper end of the dust-proof film, making it clumped at the upper end of the dust-proof film, which is convenient for discharge when the storage box moves to the other end of the frame, thereby improving the dust discharge effect.

[0045] Fifthly, by adding a second pull rope and a second spring at the two corners of the dust-proof film close to the air duct, the second insertion rod pulls the second pull rope when the second pressure rod is pressed down, thereby lifting the two corners of the upper end of the dust-proof film, so that the dust is gathered at the outlet of the middle air duct and forms a ball. Then, when the gap is opened for discharge, the airflow at the outlet of the air duct can more easily blow off the balled dust, thereby improving the dust discharge effect.

[0067] To facilitate the understanding of the present invention, the present application will be described more comprehensively below with reference to the relevant drawings; the drawings show preferred embodiments of the present invention, but the present invention can be implemented in many different forms and is not limited to the embodiments described herein; on the contrary, the purpose of providing these embodiments is to enable a more thorough and comprehensive understanding of the disclosed content of the present invention.

[0068] It should be noted that the terms “vertical”, “horizontal”, “up”, “down”, “left”, “right” and similar expressions used in this document are only for illustrative purposes and do not represent the only implementation method.

[0069] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by technicians in the technical field to which the present invention belongs; the terms used in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention; the term "and / or" used herein includes any and all combinations of one or more related listed items.

[0070] Embodiment 1: Figures 1 to 3 As shown, the present application provides a dust collection device for air outlet blades of a central air conditioner, comprising a collection box 100, a bottom plate 200 and a trigger assembly 300;

[0071] The storage box 100 is in a square frame shape and is used to collect dust from the fan blades. The storage box 100 is provided with a first through hole 110;

[0072] The first through hole 110 is disposed at one side of the bottom of the storage box 100. There are two first through holes 110 in total. The first through holes 110 are used to trigger the sliding of the component 300.

[0073] The bottom plate 200 is a hollow plate, and is disposed inside the bottom of the storage box 100. The bottom surface of the bottom plate 200 is flush with the bottom surface of the storage box 100, and the top surface of the bottom plate 200 is inclined. The wider end of the bottom plate 200 is fixedly connected to the storage box 100. The bottom plate 200 is made of silica gel, and a first air hole 210 is opened on the bottom plate 200.

[0074] The first air hole 210 is provided at one side of the bottom of the bottom plate 200, and the first air hole 210 communicates the air inside and outside the bottom plate 200 for air to pass through;

[0075] The trigger assembly 300 includes a first pressure rod 310 , and the first pressure rod 310 is slidably connected to the storage box 100 through the first through hole 110 , and the first pressure rod 310 is fixedly connected to the narrow side of the bottom plate 200 .

[0076] Specific implementation: after the storage box 100 moves to one end of the blade, the first pressure rod 310 is squeezed with the frame, and the first pressure rod 310 slides relative to the storage box 100 along the first through hole 110. The first pressure rod 310 compresses the bottom plate 200, and the bottom plate 200 becomes shorter laterally. The internal gas is discharged from the first air hole 210, and a gap is generated between the bottom plate 200 and the storage box 100. The dust slides down and is discharged along the inclined top surface of the bottom plate 200. After the storage box 100 returns, the first pressure rod 310 is no longer squeezed with the frame, and the bottom plate 200 recovers under its own elasticity. The gap between the bottom plate 200 and the storage box 100 is closed, and the bottom plate 200 continues to collect dust.

[0077] The technical solutions in the above embodiments of the present application have at least the following technical effects or advantages:

[0078] After the frame is squeezed by the first pressure rod 310, the first pressure rod 310 moves inside the storage box 100, and the first pressure rod 310 compresses the bottom plate 200. The bottom plate 200 is squeezed and becomes smaller, thereby generating a gap between the storage box 100 and the bottom plate 200. The generation of this gap is not restricted by the transverse plate, which effectively solves the problem of a small gap between the flip plate and the storage box 100 in the prior art, thereby increasing the gap for dust discharge and improving the dust discharge effect.

[0079] Embodiment 2: Considering that the dust itself is light, it is difficult for the dust to be discharged by its own gravity when the gap is opened; the embodiment of the present application is optimized based on the above embodiment.

[0080] like Figure 4-Figure 6 As shown, the bottom plate 200 further includes a second air hole 220;

[0081] The second air hole 220 is disposed at the wider end of the bottom plate 200. The second air hole 220 and the first air hole 210 are both provided with a membrane flap that limits the one-way passage of gas. The second air hole 220 can only allow gas to be discharged from the bottom plate 200, and the first air hole 210 can only allow gas to enter the bottom plate 200. An air guide tube 221 is fixedly connected to the outer side of the second air hole 220.

[0082] The air guide pipe 221 is arranged at the wider end of the bottom plate 200. The air guide pipe 221 is arc-shaped. One end of the air guide pipe 221 is fixed to the outside of the second air hole 220, and the other end of the air guide pipe 221 is fixed to the upper side of the second air hole 220. The air guide pipe 221 is used to guide the gas discharged from the second air hole 220 to the inclined top surface of the bottom plate 200.

[0083] Specific implementation: When the bottom plate 200 is squeezed and deformed, the membrane petal at the first air hole 210 prevents the gas from being discharged. Therefore, the gas inside the bottom plate 200 is discharged through the second air hole 220. The gas discharged from the second air hole 220 is guided by the air guide tube 221 and blown toward the inclined top surface of the bottom plate 200. When the gap is opened, the dust on the upper layer of the bottom plate 200 is blown off, thereby assisting the dust to be discharged from the bottom gap.

[0084] The technical solutions in the above embodiments of the present application have at least the following technical effects or advantages:

[0085] By setting the second air hole 220 and adding a membrane flap to allow air to enter the first air hole 210 and exhaust the second air hole 220, the airflow discharged from the second air hole 220 is guided to the inclined top surface of the bottom plate 200 through the air guide pipe 221. When the bottom plate 200 is deformed to produce a gap, the internal air is squeezed out to form an airflow that blows toward the inclined top surface, thereby assisting the dust to be discharged from the gap below, thereby improving the dust discharge effect.

[0086] Embodiment 3: Considering that dust may adhere to the surface of the bottom plate 200 and it is difficult for airflow to carry away the dust, the embodiment of the present application is optimized based on the above embodiment.

[0087] like Figure 7-Figure 9 As shown, the base plate 200 further includes a dustproof film 230;

[0088] The dustproof film 230 is made of TPE film. The dustproof film 230 is arranged above the bottom plate 200. The middle part of one end of the dustproof film 230 is fixedly connected to the air duct 221. The middle part of one end of the dustproof film 230 is arranged at the center of the output port of the air duct 221. The dustproof film 230 is used to collect dust falling inside the storage box 100. The other end of the dustproof film 230 is provided with a weight-increasing rod 231.

[0089] The weight-increasing rod 231 is made of metal and is used to increase weight so that one end of the dust-proof film 230 falls to the lowest point.

[0090] Specific implementation: dust gathers on the dustproof film 230. When the gap is opened, the bottom end of the dustproof film 230 falls down due to the gravity of the weight-increasing rod 231, opening the gap. At the same time, the airflow discharged from the air duct 221 passes through the upper and lower sides of the dustproof film 230, causing the dustproof film 230 to vibrate. During the vibration of the dustproof film 230, the attached dust is shaken off, and the dust that is no longer attached is discharged with the airflow on the upper side of the dustproof film 230.

[0091] The technical solutions in the above embodiments of the present application have at least the following technical effects or advantages:

[0092] A dust-proof film 230 is arranged above the bottom plate 200, and one end of the dust-proof film 230 is fixed to the middle of the output end of the air duct 221. A weight-increasing rod 231 is provided at the other end of the dust-proof film 230. When the gap is opened, the bottom end of the dust-proof film 230 falls from the gap due to gravity, and the gap is opened for dust to be discharged. At the same time, when the airflow passes through the upper and lower sides of the dust-proof film 230, the dust-proof film 230 vibrates to facilitate shaking off the dust. At the same time, the dust is discharged from the gap below with the assistance of the airflow, thereby improving the dust discharge effect.

[0093] Embodiment 4: When the fan blade is working, condensation water may be generated on its surface, causing the dust collected on the dustproof film 230 to be moist. At this time, the vibration of the dustproof film 230 cannot completely shake off the dust. The embodiment of the present application is optimized based on the above embodiment.

[0094] like Figure 10-Figure 14 As shown, the storage box 100 further includes a second through hole 120, a first fixed pulley 130, a slide groove 140, a sliding seat 150, a second movable pulley 160 and a first spring 170;

[0095] The second through hole 120 is disposed on the upper side of the other end of the storage box 100;

[0096] The first fixed pulley 130 is disposed inside the storage box 100 , the first fixed pulley 130 is located on the upper side of the second through hole 120 , and the first fixed pulley 130 is rotatably connected to the storage box 100 ;

[0097] There are two slide grooves 140, which are respectively disposed on the inner walls of both sides of the storage box 100. The slide grooves 140 are wavy in shape and the undulations of the two slide grooves 140 are opposite.

[0098] The sliding seat 150 is slidably connected to the sliding groove 140, and a threading hole is opened at the lower side of the sliding seat 150;

[0099] The second movable pulley 160 is rotatably connected to the sliding seat 150;

[0100] One end of the first spring 170 is fixedly connected to the inside of the storage box 100 , and the other end of the first spring 170 is fixedly connected to the sliding seat 150 . The first spring 170 is in a compressed state, and the first spring 170 is used to push the second movable pulley 160 to reset.

[0101] Furthermore, the dustproof film 230 also includes a first pull rope 232;

[0102] One end of the first pull rope 232 is fixedly connected to one end of the weight-increasing rod 231 , and the other end of the first pull rope 232 is fixedly connected to the upper side of the other end of the storage box 100 . The first pull rope 232 passes through the threading hole of the second movable pulley 160 , and the first pull rope 232 is wound around the first fixed pulley 130 and the second movable pulley 160 .

[0103] Furthermore, the trigger assembly 300 further includes a second pressing rod 320.

[0104] The second pressing rod 320 includes a first inserting rod 321 and a first movable pulley 322;

[0105] The first insertion rod 321 is slidably connected to the second through hole 120, and the first insertion rod 321 is used to push the first movable pulley 322;

[0106] The first movable pulley 322 is rotatably connected to one end of the first insertion rod 321 . The first movable pulley 322 is wound around and connected with the first pull rope 232 . The first movable pulley 322 is used to pull the first pull rope 232 .

[0107] Specific implementation: when the storage box 100 moves to the other end of the fan blade, the second pressure rod 320 squeezes the frame, and the second pressure rod 320 drives the first insertion rod 321 and the first movable pulley 322 to slide relative to the second through hole 120. The first movable pulley 322 pulls the first pull rope 232 during the sliding process, and due to the multiple combinations of the first fixed pulley 130 and the first movable pulley 322, the distance the first pull rope 232 is pulled is enlarged. When the other end of the first pull rope 232 is pulled, the section for the weight-increasing rod 231 to fall is first released and tightened. After continuing to pull, the weight-increasing rod 231 rises. When the weight-increasing rod 231 rises to the sliding seat 150, the weight-increasing rod 231 is stuck by the sliding seat 150 and cannot continue to rise. When it continues to be pulled, the sliding seat 150 The movable seat 150 slides along the slide groove 140, continuously compressing the first spring 170, and the weight-increasing rod 231 moves with the sliding seat 150. In the process of the weight-increasing rod 231 moving with the sliding seat 150, due to the opposite ups and downs of the trajectories on both sides, the weight-increasing rod 231 drives the dust-proof film 230 to shake, thereby assisting the dust in the lower section of the dust-proof film 230 to fall to the upper section. At the same time, due to the accumulation of dust and the humidity of the dust, the dust is easy to clump. After the second pressure rod 320 is separated from the frame, under the gravity of the first spring 170 and the weight-increasing rod 231, the dust-proof film 230 and the sliding seat 150 are reset. When the storage box 100 moves to the first pressure rod 310 to squeeze the frame, the gap opens, and the clumped dust is easier to discharge under the action of the airflow.

[0108] The technical solutions in the above embodiments of the present application have at least the following technical effects or advantages:

[0109] By adding a first pull rope 232 at both ends of the weight-increasing rod 231, a first fixed pulley 130, a slide groove 140, a sliding seat 150, a second fixed pulley 190, a first spring 170, etc. are added inside the storage box 100, and the second pressure rod 320 is cooperated, so that when the storage box 100 moves to the other side frame, the weight-increasing rod 231 is pulled up by the pull rope and moves to the other end of the storage box 100. At the same time, the ups and downs of the two slide grooves 140 are opposite, so that the weight-increasing rod 231 can also be shaken when moving with the sliding seat 150, thereby shaking off the dust to the upper end of the dust-proof film 230, so that the dust is clumped at the upper end of the dust-proof film 230, which is convenient for discharge when the storage box 100 moves to the other end of the frame, thereby improving the dust discharge effect.

[0118] Furthermore, the dust-proof film 230 further includes a second spring 234;

[0119] One end of the second spring 234 is fixedly connected to a corner of the dustproof film 230 close to the air guide tube 221 , and the other end of the second spring 234 is fixedly connected to the inner side of the storage box 100 . The second spring 234 is used to reset the dustproof film 230 .

[0120] The technical solutions in the above embodiments of the present application have at least the following technical effects or advantages:

[0121] By adding a second pull rope 233 and a second spring 234 at the two corners of the dustproof film 230 close to the air duct 221, the second insertion rod 323 pulls the second pull rope 233 when the second pressure rod 320 is pressed down, thereby lifting the two corners of the upper end of the dustproof film 230, so that the dust is gathered at the outlet of the middle air duct 221 and forms a ball. When the gap is opened for discharge, the airflow at the outlet of the air duct 221 can more easily blow off the balled dust, thereby improving the dust discharge effect.
