Description

Technical Field

[0001] The present invention relates to the field of protection technology, in particular to a ventilation protection component for an outdoor unit of an air conditioner. Background Art

[0002] When installing a home air conditioner, the outdoor unit may be installed outdoors due to space and design constraints. It is used to cool and dissipate the high-pressure and high-temperature gas discharged from the indoor unit through the outdoor unit. The condensed refrigerant is then transported to the evaporator of the indoor unit to absorb the indoor heat. This cycle is repeated to achieve the required indoor temperature.

[0003] Since the air conditioner outdoor unit needs to be installed outdoors to remove heat, except for the top floor, most of the outdoor units are installed on the outer wall of the floor. The air conditioner outdoor unit is hung outdoors all year round and is often exposed to the sun, rain, wind and dust, which can easily cause dust blockage and affect heat removal. It is inconvenient to disassemble when using a canopy, and using the air conditioner under the canopy is not conducive to air circulation. The hot air discharged from the air conditioner outdoor unit may be absorbed again, resulting in a decrease in the cooling efficiency of the internal coolant, which is not conducive to air circulation and internal cooling.

[0038] The present invention has the following beneficial effects:

[0039] 1. The present invention aims to solve the problems of protecting dust and promoting air circulation. When the air-conditioning outdoor unit fixedly connected to the inside of the bracket is started, the side wall of the air-conditioning outdoor unit contacts the outer wall of the compression air duct, and the air-conditioning outdoor unit discharges the heat discharged by the indoor unit through the internal circulation of the compression air duct. When the airflow discharged from the exhaust port of the air-conditioning outdoor unit enters the inside of the compression air duct, the space becomes smaller and the pressure increases, causing the discharged hot air and heat to accelerate to a certain extent. Another part of the airflow flows along the outer wall of the compression air duct, and there is gas circulation inside several ventilation holes on the outer wall of the compression air duct. Due to the pressure difference between the internal airflow of the compression air duct and the external air, the airflow is accelerated and discharged through the ventilation holes. The mainstream gas inside the compression air duct hits the filter cotton for filtration and is then discharged to the outside of the bracket, which promotes the circulation of the air inside the bracket to a certain extent and promotes the circulation with the external air.

[0040] 2. The present invention aims at the possibility of blockage caused by dust or lint that may be carried during external air circulation. According to the above working behavior, the frequency of use of the equipment increases in summer. When in use, after the airflow at the exhaust port of the air-conditioning outdoor unit is guided and discharged through the compressed air duct, the airflow at the ventilation hole will gradually produce a siphon phenomenon of the airflow or air outside the bracket, which is filtered through the filter cotton to reduce the dust and impurities carried. When rainwater enters the water inlet trough, it will be guided along the inner wall of the flow trough and flow out through the drainage port to flush the filter cotton at the bottom of the drainage port. The flushed sewage will flow along the surface of the water diversion slope to the inside of the drainage trough and be guided to flow out, reducing the accumulation of rainwater and the foaming and soaking of the wall surface, thereby reducing the frequency of cleaning of the air-conditioning outdoor unit and the degree of blockage of dust and impurities.

[0041] 3. The present invention aims to address the problem that in windy weather, the equipment may be installed on the side wall of the wall and be affected by the wind. After the equipment is installed, when encountering strong winds, when ventilation is carried out from the side wall, the wind will be dispersed by the inclined plate 1 and the inclined plate 2 when hitting the side wall of the bracket. When part of the wind hits the side wall of the cover plate, the wind will flow along the inner wall of the wind guide cavity, generating an upward inclined wind flow path, and impacting the wind on the top of the cover plate to slow down the flow rate above. At the same time, part of the wind dispersed by the inclined plate 1 and the inclined plate 2 will flow directly to the outside, and the other part will flow along the inner wall of the exhaust port, merge after impacting the wind in the wind guide cavity, and flow along the inner wall of the wind guide cavity, reducing the impact of the continuous wind, which is beneficial to the diversion so that the wind bodies offset each other to partially reduce the potential energy, and at the same time guide the flow direction of the wind to reduce the impact of the wind.

[0042] 4. The present invention can clean the attached dust and impurities to a certain extent. After the equipment is installed on the outer wall of a higher floor, the higher the floor, the fewer buildings or objects that obstruct it, and the air flow is smoother, which makes the air flow more frequent. When the hood rotates and drives the coaxial convex gear to rotate, the outer wall of the coaxial convex gear will engage with the driven rack frame to make a corresponding translation, and the movement of the limit frame corresponds to the movement of the traction scraper, so that the attached dust wants to fall off to the inside of the drain groove, and is pushed out of the drain groove by the push of the bottom side wall of the rotating roller. After the coaxial convex gear rotates to the other half circle, it engages with the teeth of the driven rack frame away from the rotating roller, so that the driven rack frame is translated and reset, and the two rotating rollers are pulled again to translate and scrape, thereby reducing the degree of dust adhesion, reducing dust accumulation, and reducing the situation where manual cleaning of the air conditioner outdoor unit may be frequent due to installation at high altitude outside.

[0043] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

The impact of the wind carried by the wind when passing through the surface of the cover plate 211 is reduced, and the wind is allowed to circulate through guidance.

[0085] The liquid flow assembly 22 includes a plurality of drainage ports 222 fixedly connected to the inside of the cover plate 211. The top of the flow channel 221 is provided with an anti-immersion groove 223. The top of the cover plate 211 is rotatably connected to the water inlet groove 214.

[0086] Among them, the flow groove 221 is connected to the water inlet groove 214; the rainwater accumulated on the top of the cover plate 211 is reduced from bubbling with the wall surface, and the rainwater collected in the water inlet groove 214 is used to flush the filter cotton 122.

[0087] The transmission assembly 31 includes a coaxial convex gear 311 meshed with the outer wall of the hood 224. A limiting frame 312 is fixedly connected to the side wall of the cover plate 211. A driven rack frame 313 is meshed with the outer wall of the coaxial convex gear 311. A sliding slot 314 is defined at the top of the cover plate 211.

[0088] The outer wall of the driven rack frame 313 is slidably connected to the interior of the sliding groove 314 ; the wind hood 224 is driven by the wind to transmit force, driving the convex gear 311 to rotate and interfere with the movement of the driven rack frame 313 .

[0089] The moving assembly 32 includes two rotating rollers 321 extending through the outer wall of the driven rack frame 313. A receiving plate 322 is fixedly connected to the side wall of the rotating roller 321. The side wall of the receiving plate 322 has two receiving grooves 323 formed therein. A scraper 324 is slidably connected to the interior of the receiving groove 323.

[0090] Among them, a plurality of compression springs are fixedly connected to the side of the scraper 324 close to the receiving plate 322, and the end of the compression spring away from the scraper 324 is fixedly connected to the inner wall of the receiving groove 323; by converting the force, the rotating roller 321 moves inside the limit frame 312 to scrape the surface of the filter cotton 122 and the inclined plate 112 to reduce dust accumulation.

[0091] In a specific embodiment of the present invention, when the air-conditioning outdoor unit 14 fixedly connected to the inside of the bracket 111 is started, the side wall of the air-conditioning outdoor unit 14 contacts the outer wall of the compression air duct 121, and the air-conditioning outdoor unit 14 discharges the heat discharged by the indoor unit through the internal circulation of the compression air duct 121. When the airflow discharged from the exhaust port of the air-conditioning outdoor unit 14 enters the interior of the compression air duct 121, the space becomes smaller, resulting in an increase in pressure, causing the discharged hot air and heat to accelerate to a certain extent. Since the size of the air outlet of the air-conditioning outdoor unit 14 is different from that of the air inlet of the compression air duct 121, the discharged airflow is divided into multiple parts, and part of the airflow passes through the compression air duct 121. The internal circulation of the compressed air duct 121 generates an accelerated flow, while another part of the air flows along the outer wall of the compressed air duct 121. Gas circulates inside the several ventilation holes on the outer wall of the compressed air duct 121. Due to the pressure difference between the internal airflow of the compressed air duct 121 and the external air, the airflow is accelerated and discharged through the ventilation holes. The flow potential energy carried by the airflow dispersed by the ventilation holes interferes with the air inside the bracket 111, causing circulation. The mainstream gas inside the compressed air duct 121 impacts the filter cotton 122 for filtration before being discharged to the outside of the bracket 111, which promotes the circulation of the air inside the bracket 111 to a certain extent, promoting circulation with the external air.

[0092] According to the above working behavior, the frequency of use of the equipment increases in summer. When in use, when the air outlet of the air-conditioning outdoor unit 14 is working, the air flow is guided and discharged through the compressed air duct 121, and the air flow at the ventilation hole will gradually produce a siphon phenomenon of the air flow or air outside the bracket 111. The air inside and outside the bracket 111 are alternately accelerated through the flow rate difference, and part of the air will enter along one side of the air outlet of the air-conditioning outdoor unit 14, and be filtered through the filter cotton 122 to reduce the dust and impurities carried. The continuous operation of the air-conditioning outdoor unit 14 causes the filter cotton 122 to adhere to a certain degree of dust or lint. The continued warming of the weather will prompt the formation of rain clouds. When rain enters the inlet When the water is in the water tank 214, it will be guided along the inner wall of the flow groove 221 and flow out through the drainage port 222 to flush the filter cotton 122 at the bottom of the drainage port 222. The flushed sewage will flow along the surface of the water diversion slope 124 to the inside of the drainage groove 123 and be guided out. Since the equipment is usually installed outside close to the wall, when rainwater collects on the top of the cover plate 211, some of the accumulated rainwater is guided to the sides along the inside of the anti-immersion groove 223, reducing the accumulation of rainwater and the resulting foaming and soaking of the wall surface. This will extend the service life of the equipment to a certain extent and reduce the frequency of cleaning of the air conditioner outdoor unit 14 and the degree of clogging caused by dust and impurities.

[0093] After the equipment is installed, in the case of strong winds, when ventilation is carried out from the side wall, the wind will be dispersed by the inclined plate 112 and the inclined plate 213 when it hits the side wall of the bracket 111. When part of the wind hits the side wall of the cover plate 211, the wind will flow along the inner wall of the wind guide cavity 212, generating an upward inclined wind flow path, and impacting the wind on the top of the cover plate 211 to slow down the flow rate above. At the same time, part of the wind dispersed by the inclined plate 112 and the inclined plate 213 will flow directly to the outside, and the other part will flow along the inner wall of the exhaust port 213, and after impacting the wind in the wind guide cavity 212, it will merge and flow along the inner wall of the wind guide cavity 212, reducing the impact of the continuous wind, which is beneficial to the diversion so that the wind can offset each other and reduce the potential energy, and at the same time guide the flow direction of the wind to reduce the impact of the wind.

[0094] When the equipment is installed on the outer wall of a higher floor, as the floor is higher, there are fewer buildings or objects that obstruct it, and the air flow is smoother, which makes the air flow more frequent. When the air flow blows along the side wall of the bracket 111, the air flow is deflected along the inside of the air guide cavity 212. The interfered air flow and the air flow flowing through the top of the cover plate 211 offset each other and then merge and circulate. The circulating air flow drives the hood 224, causing the hood 224 to rotate and drive the coaxial convex gear 311 to rotate, and the outer wall of the coaxial convex gear 311 will engage the driven rack frame 313 for corresponding translation. According to the shape of the driven rack frame 313 being a cam structure part, please refer to the following for details. Figure 9 The middle part, and one side of the coaxial convex gear 311 lacks some teeth. When the coaxial convex gear 311 rotates half a circle, it drives the driven rack frame 313 to pull the two rotating rollers 321 to slide along the inner wall of the limit frame 312, and the movement of the limit frame 312 corresponds to the movement of the traction scraper 324. When the limit frame 312 moves, the scraper 324 will be separated from the squeezing of the inner wall of the bracket 111. Under the influence of the outer wall of the scraper 324 not being squeezed, the compression spring at the side wall is extended, which will push the scraper 324 close to the side wall of the filter cotton 122. The surface of the filter cotton 122 is scraped to a certain extent, so that the attached dust is separated from the inside of the drainage groove 123 and pushed out of the drainage groove 123 by the bottom side wall of the rotating roller 321. After the coaxial convex gear 311 rotates to another half circle, it meshes with the teeth of the driven rack frame 313 on the side away from the rotating roller 321, causing the driven rack frame 313 to move horizontally and reset. Similarly, the two rotating rollers 321 are pulled horizontally again to scrape, thereby reducing the degree of dust adhesion and dust accumulation, and reducing the situation where frequent manual cleaning of the air conditioner outdoor unit 14 due to installation at a high altitude is required.
