Condenser Cleaning System

Abstract

A condenser cleaning system comprises of a cleaning unit with a mounting flange which is used to securely place the cleaning unit in between a condenser and a mesh. The mesh is placed on the cleaning unit using a bent edge. The cleaning unit has a cleaner that moves over a plurality of heat exchange fins of the condenser removing debris and the cleaner also moves over the mesh removing debris.

As the cleaner, preferably in a form of a brush roller, moves over the plurality of heat exchange fins, the cleaner displaces debris collected on the plurality of heat exchange fins.

DETAILED DESCRIPTION EMBODIMENTS

[0030] FIG. 1 shows a condenser cleaning system 10 comprising a cleaning unit 15 with a mounting flange 20 that is used to securely place the cleaning unit in between a condenser 25 and a mesh 30. The mesh 30 is placed on the cleaning unit using a bent edge 35. The cleaning unit has a cleaner 40 that moves over a plurality of heat exchange fins 45 of the condenser removing debris and the cleaner also moves over the mesh removing debris.

[0031] The plurality of heat exchange fins are attached to a condensing tube 50 and the plurality of heat exchange fins 45 are parallelly aligned so that the cleaner may slidably move along the length of the plurality of heat exchange fins 45. Although the FIG. 1 shows the plurality of heat exchange fins 45 are vertically laid, it is possible to have the plurality of heat exchange fins 45 laid horizontally. When the plurality of heat exchange fins 45 are vertically laid, in the direction of the cleaner 40 moving up and down the cleaning unit 15, the cleaner 40 may clean both surfaces of the plurality of heat exchange fins 45 better. In other words, although it is preferable to have the cleaner 40 move along the lengths of the plurality of heat exchange fins 45, it is possible to have the cleaner 40 move against the lengths of the plurality of heat exchange fins 45. As the cleaner 40 moves over the plurality of heat exchange fins 45, the cleaner 40 displaces debris collected on the plurality of heat exchange fins 45.

[0032] FIG. 2 shows the cleaning unit 15 with two mounting flanges 20 attached to the condenser 25. The mounting flanges 20 at two ends of the cleaning unit 15 are used to securely hold the cleaning unit 15 to the condenser 25.

[0033] A motor 55 is attached to the cleaner 40 moves the cleaner 40 on one or more tracks 60 of the cleaning unit 15. Tracks 60 may have grooves 65 so the cleaner 40 moves along the tracks 65 as the cleaner 40 rotates cleaning both the plurality of heat exchange fins 45 and the surface of mesh 30 (not shown in FIG. 2; see FIGS. 4 and 6). Different embodiments may use other means of moving the motor on the tracks 60, as well as other means of moving the cleaner 40 up and down, left and right across the plurality of heat exchange fins and the mesh 30.

[0034] As shown in FIGS. 1, 4 and 6, the mesh 30 is mounted on the cleaning unit 15 covering the cleaning unit 15 so that the cleaning unit 15 with the cleaner 40 is in between the mesh 30 and the plurality of heat exchange fins 45. Because the cleaner 40 is sandwiched in between the plurality of heat exchange fins 45 and the mesh (30), the cleaner 40 simultaneously cleans both the plurality of heat exchange fins 45 and the mesh 30 to their most cleanliness, enhancing the efficiency of the condenser 25.

[0035] FIG. 3 is a cut-away view from the top of the cleaning unit 15 and the condenser 25 showing the cleaner40 cleaning the plurality of heat exchange fins 45. In FIG. 3, the cleaner 40 is a brush 70 (40) with a plurality of bristles 75 that are always in contact with the plurality of heat exchange fins 45 and the mesh 30. However, a different embodiment may use a brush 45 that has a set of bristles 75 that are alternatingly turned toward the plurality of heat exchange fins 45 or turned toward the mesh 30 so that the plurality of bristles 75 clean the plurality of heat exchange fins 45 or the mesh 30 alternatingly as the brush 70 moves along the one or more tracks 60 (shown in FIGS. 2 and 5).

[0036] The cleaner may be made of various materials, such as cloth, microfiber, sponge and other materials, but a round brush 80 which is a roller 80 may provide the best utility. Thus, a brush 70 with a plurality of bristles 75 protruding simultaneously toward both the plurality of heat exchange fins 46 and the mesh 30 is used to clean both the plurality of heat exchange fins 45 and the mesh 30 simultaneously when the brush moves along the one or more tracks. As mentioned, the brush 70 that is a roller 80 (as shown in FIGS. 1, 2, 3, 5-7) so that the plurality of bristles 75 are radially protruding is believed to be the best in cleaning both the plurality of heat exchange fins 45 and the mesh 30 simultaneously. AS a brush roller 80 is used, driven by the motor, the plurality of bristles 75 clean both the plurality of heat exchange fins 45 and the mesh 30 simultaneously with a rotating action.

[0037] Because it is possible that the cleaner 30, in its in between the plurality of bristles 75, collect debris itself, the cleaning 15 unit may also comprise a dust scraper 85 having a comb-shaped protrusions 90 attached to the cleaning unit 15 and in contact with the plurality of bristles 76 to remove any debris off the roller 80 as the roller 80 rotates to maintain the plurality of bristles 75 clean. The comb-shaped protrusions 90 are attached to two ends of the roller 95 to maintain the comb-shaped protrusions 90 at a predetermined distance from the center of the roller 100 (shown in FIG. 6). The distance between the comb-shaped protrusions 90 and the center of the roller 100 may be adjustable.

[0038] FIG. 4 is a perspective view showing the mesh 30 covering the cleaning unit 15. As shown in FIG. 4, the mesh 30 may be a fine mesh 105 as depicted on the right side of the mesh 30 or a grill 110 as depicted on the left upper side of the mesh 30. The mesh 30 is preferably made of aluminum or stainless steel to prevent corrosion, but may be made of other materials, including but not limited to, plastic or steel. The mesh 30 has the bent edge 35 that is used to securely hold the mesh 30 to the cleaning unit 15.

[0039] FIG. 5 is a perspective view showing the cleaning unit 15 having a dust scraper 85 with a plurality of comb-shaped protrusions 90 that is used to clean the cleaner 40 (and its plurality of bristles 75, when the bristles are used in an embodiment). FIG. 5 also shows the tracks 60 on which the cleaner 40 moves along using the grooves 65. Although the tracks 60 with the grooves 65 are used in this embodiment, the invention is not limited to the use of tracks 60 and/or grooves 65, as other conventional moving a roller along a track means may be used, including but not limited to, as illustrated in U.S. Pat. No. 9,593,895.

[0040] FIG. 6 is a cut-away view of a cleaner 40 engaging both the plurality of heat exchange fins 45 and the mesh 30. The plurality of bristles 75 of the roller 80 (the cleaner 40) extend in between the plurality of heat exchange fins 45 and extend in and through the mesh 30. As the center of the roller 100 is rotated by the motor 55 (shown in FIG. 2), the plurality of bristles 75 rotate and wipes off any debris collected on the plurality of heat exchange fins 45 and wipes off any debris collected on the mesh 30.

[0041] FIG. 7 is a side view of a cleaner 40 that is a round brush 70 in the form of a roller 80. The plurality of bristles 75 radially extends out forming the roller 80.

[0042] While the invention has been shown and described with reference to different embodiments thereof, it will be appreciated by those skilled in the art that variations in form, detail, compositions and operation may be made without departing from the spirit and scope of the invention as defined by the accompanying claims. In addition, although this invention describes a condenser 25 used in refrigerators or freezers, the invention and the scope of the claims are not limited to the refrigerators and freezers and other food related industry, but also air conditioners and other heat exchangers having heat transfer fins 45.
