Description

Technical Field

[0001] The utility model relates to the field of condensers, in particular to an air-conditioner outdoor unit condenser. Background Art

[0002] The condenser is a component of the refrigeration system and a type of heat exchanger. It can convert gas or steam into liquid and transfer the heat in the pipe to the air near the pipe in a very fast manner.

[0003] A Chinese patent with announcement number CN213300460U discloses a protective cleaning device for an air-conditioning outdoor unit condenser, comprising an outer frame bracket, a plurality of filter strips fixedly arranged inside the outer frame bracket, a slide groove is respectively arranged at the left and right ends of the front end of the outer frame bracket, a cleaning cross bar with a cleaning brush is movably arranged at the front end of the slide groove, a slider is respectively arranged in the two slide grooves, the two ends of the cleaning cross bar are respectively fixed to the two sliders, electric push rods are respectively arranged at the two ends of the top of the outer frame bracket, and the protruding ends pass through the outer frame bracket and are inserted into the slide groove, a connecting component for connecting the two is arranged between the electric push rod and the slider, and the connecting component includes a flange plate arranged at one end of the slider close to the electric push rod and a connecting disc arranged at the end of the protruding end of the electric push rod for connecting to the flange plate.

[0004] The above structure can start the electric push rod arranged on the top of the outer shell bracket when there are a lot of debris on the filter strip, so that the sliders in the two slide grooves can be lifted and lowered in the slide grooves. When the sliders are lifted and lowered in the slide grooves, the cleaning cross bars connected to the sliders at both ends will move along with the sliders, so that the cleaning brush on the cleaning cross bar can clean the debris on the filter strip. However, the bristles on the cleaning brush will gradually be damaged after long-term use, and the cleaning brush needs to be replaced at this time. However, to remove the cleaning brush from the above structure, it is necessary to first release the connection between the flange on the slider and the connecting disc on the electric push rod, and then take the slider out of the slide groove on the outer frame bracket. Only then can the cleaning brush be removed from the outer frame bracket for replacement, which makes the replacement of the cleaning brush more troublesome. Utility Model Content

[0005] The utility model aims to solve the problem that the bristles of the cleaning brush in the prior art will gradually be damaged after long-term use, and the cleaning brush needs to be replaced at this time. To replace the cleaning brush, the connection between the flange on the slider and the connecting disc on the electric push rod must be released first, and then the slider needs to be taken out of the slide groove on the outer frame bracket. Only then can the cleaning brush be removed from the outer frame bracket for replacement, which leads to the disadvantage that the replacement of the cleaning brush is troublesome. The utility model provides an air-conditioning outdoor unit condenser with a dust cover and a self-cleaning structure on the dust cover, which is easy to replace.

[0006] In order to solve the above technical problems, the utility model is solved by the following technical solutions:

[0007] A condenser of an air conditioner outdoor unit comprises a dust cover with a filter screen inside that can be installed outside the condenser and is used to reduce dust from entering the condenser. A slide groove is respectively arranged on the dust cover at both ends of the filter screen, and a slider that can slide in the slide groove is respectively arranged in the two slide grooves. A brush is arranged at one end of the two sliders away from the slide groove, and the two ends are respectively connected to the two sliders and can clean the filter screen by following the movement of the sliders. The two ends of the brush are connected to the two sliders by a detachable structure. The detachable structure comprises a plug-in groove arranged on the two sliders for inserting the end of the brush and a limiting component arranged in the plug-in groove for reducing the probability of the brush detaching from the slider.

[0008] By adopting the above scheme, dust and the like can be blocked by the filter screen arranged on the dust cover, thereby reducing the probability of dust and the like entering the condenser, and the arranged brush can be moved on the dust cover through the cooperation of the slider and the slide groove, thereby sweeping the dust and the like on the filter screen off the filter screen. Since the two sliders are provided with plug-in grooves for inserting the ends of the brushes, the probability of the brushes detaching from the sliders due to their own weight is reduced. At the same time, the limiting component arranged can limit the end face of the brush in the plug-in groove, thereby reducing the probability of the brushes detaching from the plug-in groove, thereby ensuring the normal use of the brush. Since the brush is installed on the two sliders through a detachable structure, when the brush is damaged after long-term use, the brush can be removed from the two sliders for replacement.

[0009] Preferably, the limiting component includes an L-shaped limiting plate arranged opposite to each other in the two slide grooves and abutting against the side wall and top surface of the brush end when the brush end is inserted into the slide groove, and a rotating component driving the L-shaped limiting plate when the brush is inserted into the slide groove.

[0010] Preferably, the rotating component includes a rotating plate arranged at the bottom of the slide groove and parallel to the bottom of the slide groove, hinge holes arranged at the plate ends perpendicular to the bottom of the slide groove near the limiting plate on both sides of the side wall of the slide groove, a plug hole arranged on the limiting plate at a position opposite to the position of the hinge hole, and a hinge shaft passing through the two hinge holes and the plug hole at the same time.

[0011] By adopting the above scheme, the limit plate and the rotating plate can be flipped in the plug-in slot through the provided hinge shaft. When the end of the brush is inserted into the plug-in slot, the rotating plate and the limit plate can be rotated first, so that the limit parts of the two sliders are in a mutually expanded state. When the brush is gradually inserted into the plug-in slot, the end face of the brush will gradually abut against the rotating plate, and the rotating plate will rotate with the insertion of the end face of the brush. When the rotating plate rotates, it will drive the limit plate to flip together, so that the limit plate limits the end of the brush inserted into the plug-in slot, thereby reducing the probability of the brush falling off the slider.

[0012] Preferably, the lateral length of the rotating plate is greater than the lateral length of the plate section of the limiting plate parallel to it.

[0013] By adopting the above scheme, the lateral length of the rotating plate is set to be greater than the lateral length of the plate end parallel to the limiting plate, so that when the end of the brush is inserted into the plug-in slot, it is easier to abut against the rotating plate, so that the rotating plate and the L-shaped limiting plate rotate together, thereby limiting the end face of the brush between the L-shaped limiting plate and the rotating plate.

[0014] Preferably, a lifting component for driving two sliders connected to each other through brushes to rise and fall synchronously and a guide component for guiding the rising and falling of the sliders are respectively provided in the two slide grooves.

[0015] Preferably, the lifting component includes a screw rod arranged in one of the slide grooves along the extension direction of the slide groove and a motor arranged on the top of the dust cover for driving the screw rod to rotate, and a slider in the slide groove where the screw rod is arranged is arranged on the screw rod.

[0016] By adopting the above scheme, the motor can be used to drive the screw in the slide groove to rotate. When the screw rotates, the slider arranged on the screw will move up and down in the slide groove along with the rotation of the screw. At this time, the brush arranged on the slider through the detachable component will rise and fall with the slider. When the brush rises and falls, it can brush off the dust and other objects attached to the filter screen, thereby making the cooling effect of the condenser more stable and increasing its service life.

[0017] Preferably, the guide component comprises guide columns which are arranged in a slide groove without a lifting component and connected to the inside of the slide groove at both ends along the extension direction of the slide groove, and a through hole for the guide column to pass through is arranged on the slider in the slide groove without a lifting component.

[0018] By adopting the above scheme, the through holes arranged on the slider allow the guide column to pass through them. When the lifting component drives the slider in the slide groove to rise and fall, the brush will rise and fall along with the slider. Since the slider in the slide groove far away from the lifting component is connected to the slider at the lifting component through the brush, the slider far away from the lifting component can be lifted and lowered together. At this time, the guide column will guide the lifting and lowering of the slider, reducing the probability of the slider being offset during lifting and lowering and falling out of the slide groove due to the center of gravity, thereby making the lifting and lowering of the brush more stable.

[0019] The utility model has remarkable technical effects due to the adoption of the above technical scheme: dust and the like can be blocked by the filter screen arranged on the dust cover, thereby reducing the probability of dust and the like entering into the condenser, and the arranged brush can be moved on the dust cover through the cooperation of the slider and the slide groove, thereby sweeping the dust and the like on the filter screen off the filter screen, because the two sliders are provided with plug-in grooves for inserting the ends of the brush, thereby reducing the probability of the brush detaching from the slider due to its own weight, and the limiting component arranged at the same time can limit the end face of the brush in the plug-in groove, thereby reducing the probability of the brush detaching from the plug-in groove, thereby ensuring the normal use of the brush, because the brush is installed on the two sliders through a detachable structure, when the brush is damaged after long-term use, the brush can be removed from the two sliders for replacement.

[0027] Example

[0028] A condenser of an air conditioner outdoor unit, reference body 1, includes a dust cover 1 with a filter 2 inside that can be installed outside the condenser for reducing dust from entering the condenser, a slide groove 3 is respectively provided on the dust cover 1 at both ends of the filter 2, a slider 4 that can slide in the slide groove 3 is respectively provided in the two slide grooves 3, a brush 14 is provided at one end of the two sliders 4 away from the slide groove 3, and the two ends are respectively connected to the two sliders 4 and can follow the movement of the sliders 4 to clean the filter 2, the two ends of the brush 14 are connected to the two sliders 4 by a detachable structure, and the detachable structure includes a plug-in groove 5 provided on the two sliders 4 for inserting the end of the brush 14 and a limiting component provided in the plug-in groove 5 for reducing the probability of the brush 14 detaching from the slider 4.

[0029] refer to Figure 1-Figure 5 The limiting component includes an L-shaped limiting plate 6 which is relatively arranged in the two slide grooves 3 and abuts against the side wall and the top surface of the end of the brush 14 when the end of the brush 14 is inserted into the slide groove 3, and a rotating component that drives the L-shaped limiting plate 6 when the brush 14 is inserted into the slide groove 3. The rotating component includes a rotating plate 7 which is arranged at the bottom of the slide groove 3 and is parallel to the bottom of the slide groove 3, hinge holes 9 are respectively arranged at the plate ends of the two side walls of the slide groove 3 near the limiting plate 6 and perpendicular to the bottom of the slide groove 3, and a plug hole 10 is arranged on the limiting plate 6 at a position opposite to the hinge hole 9, and a hinge shaft 8 that simultaneously passes through the two hinge holes 9 and the plug hole 10. In this embodiment, there is damping for the rotation between the hinge shaft 8 and the limiting plate 6, so that the limiting plate 6 can be in a mutually expanded state after being flipped, so that people can install the brush 14 on the slider 4. The horizontal length of the rotating plate 7 is greater than the horizontal length of the plate section of the limiting plate 6 parallel to it.

[0030] A lifting component for driving two sliders 4 connected to each other by a brush 14 to rise and fall synchronously and a guide component for guiding the rising and falling of the sliders 4 are respectively provided in the two slide grooves 3. The lifting component includes a screw rod 11 arranged in one of the slide grooves 3 along the extension direction of the slide groove 3 and a motor 12 arranged on the top of the dust cover 1 for driving the screw rod 11 to rotate. The slider 4 in the slide groove 3 with the screw rod 11 is arranged on the screw rod 11. The guide component includes a guide column 13 connected to the inside of the slide groove 3 at both ends arranged along the extension direction of the slide groove 3 in the slide groove 3 where the lifting component is not provided. A through hole for the guide column 13 to pass through is provided on the slider 4 in the slide groove 3 where the lifting component is not provided.

[0031] Specific replacement process of the brush 14: when the brush 14 needs to be installed on the two sliders 4, first, rotate the two L-shaped limit plates 6 and the rotating plate 7 to make the two limit parts in a mutually expanded state, and then, the end of the brush 14 can be inserted into the plug-in slot 5 on the slider 4. When the end of the brush 14 is gradually inserted into the plug-in slot 5, the end of the brush 14 will gradually abut against the rotating plate 7. At this time, the end of the brush 14 will squeeze the rotating plate 7 to flip over, and the set limit plate 6 will flip over with the rotating plate 7. At this time, the limit plate 6 will gradually flip over to limit the end of the brush 14, thereby reducing the probability of the brush 14 detaching from the slider 4; and when the brush 14 needs to be removed and replaced, it is only necessary to flip the limit plates 6 on both sides with force. The limit plate 6 is flipped, and the limit plate 6 will release its limit on the end of the brush 14. When the brush 14 is installed, the motor 12 can be started to drive the screw rod 11 to rotate. When the screw rod 11 rotates, the slider 4 arranged on the screw rod 11 will perform a lifting movement in the slide groove 3. Because the slider 4 in the other slide groove 3 is connected with the slider 4 performing the lifting movement through the brush 14, when the slider 4 on the screw rod 11 performs a lifting movement, the slider 4 in the other slide groove 3 will slide in the slide groove 3, and the guide column 13 provided will guide the lifting of the slider 4, and the lifting of the brush 14 will clean the dust on the filter screen 2, so that the refrigeration effect of the condenser is more stable and the service life is longer.
