If rain, no matter how mild, is not diverted away from the dwelling, water can damage the ground next to the foundation. Prolonged water exposure along the foundation erodes the soil and can seep down along the foundation, increasing the risk of basement leak and structural corrosion. Moreover, gutters that safely manage storm water do more than simply protect the dwelling.

- One such design includes placing a hood or a non-porous cover over the gutter trough to block the debris from falling into the trough.
- the capillary action of the water adhering to the cover diverts the water into the trough.
- this system could lack efficiency in heavier storms, as an amount of water may fail to divert into the trough through the cohesion action of water with the surface of the cover.
- Another solution has been to cover the trough with a porous or mesh filter, which allows water but not debris to enter into the trough.
- the present invention is a Stahled gutter that is easy to maintain and clean and efficient in capturing rain water.
- the embodiments of the present inventions are directed to a dwelling water drainage system.

- the gutter system further includes an actuating mechanism, in communication with the controller, for movably operating a wall of the gutter system from a closed position to perform the water collection function mode to an open position to perform the self-cleaning function mode.
- the actuating mechanism moves the wall from a generally horizontal position, in the closed position, to a generally vertical or angled position, in the open position, to cause debris to fall out of the gutter system.
- the actuating mechanism is configured to apply a vibration motion to the wall of the gutter system to assist in the removal of debris.
- the controller is configured to set the duration of the vibration motion applied by the actuating mechanism to the wall.
- the controller can also be configured to set the degree of the vibration motion applied by the actuating mechanism to the wall.

Description
- This invention relates to a gutter system for a residential or commercial building. More specifically, the invention relates to a self-cleaning and smart gutter system for easy removal of debris.
- A gutter is on every house and commercial building to guide rain and storm water off the roof and away from the foundation of the house and building. A gutter is critical for maintaining a sound structure and preventing structural damage to the dwelling. If rain, no matter how mild, is not diverted away from the dwelling, water can damage the ground next to the foundation. Prolonged water exposure along the foundation erodes the soil and can seep down along the foundation, increasing the risk of basement leak and structural corrosion. Moreover, gutters that safely manage storm water do more than simply protect the dwelling. Gutters also preserve the yard because rainwater could cut pathways through the yard, creating ditches and pooling in low-sloped areas.
- The most common problem is keeping the gutter clean and free from debris. Storms and change in seasons cause debris, such as leaves, twigs, and dirt, to clog the gutter. Rainwater trapped in a clogged gutter or downspout has nowhere to go but over the edge of the trough, rendering the gutter useless. Moreover, if the debris remains during winter, snowmelt can pool and refreeze in the gutters, potentially weighing them down and causing the gutter to break from the dwelling. Clogged gutters also increase the risk of ice dams forming at the edge of the roof. Contractors commonly recommend cleaning gutters at least twice a year—more specifically once in the spring and again in the fall or before winter arrives. With traditional gutters, there are two maintenance options. The owner of the dwelling can climb a ladder and clean out the debris by hand. While this saves money, it frequently results in many accidents and injuries. The second option is to pay a professional gutter-cleaning crew to clear the gutters and downspouts, which can be expensive.
- Various entities have invented and sold different gutter designs aimed at solving the maintenance problem. One such design includes placing a hood or a non-porous cover over the gutter trough to block the debris from falling into the trough. The capillary action of the water adhering to the cover diverts the water into the trough. However, this system could lack efficiency in heavier storms, as an amount of water may fail to divert into the trough through the cohesion action of water with the surface of the cover. Another solution has been to cover the trough with a porous or mesh filter, which allows water but not debris to enter into the trough. In heavier storms, however, the capillary action of the water on the filter's surface can cause the water to run-off, resulting in less than an ideal amount of water to be captured by the trough. Additionally, debris can also get stuck in the filter and accumulate on top of the filter, which not only causes even more run-off water but also creates the need to clean the filters. Cleaning mesh filters can be even more difficult than cleaning plain gutters without a filter. In winter season, the mesh filter can also freeze-up, resulting in a heavy buildup of ice. Once the ice melts, the water pours onto the foundation of the house or the driveway, causing damage and hazardous conditions should the water refreeze.
- With the advancement of home technology, many components are becoming smart features. The present invention is a reinvented gutter that is easy to maintain and clean and efficient in capturing rain water.
- The embodiments of the present inventions are directed to a dwelling water drainage system. The dwelling water drainage system comprises a gutter system having a water collection function mode for collecting and diverting water during rain and a self-cleaning function mode for cleaning debris from the gutter system. A controller (e.g., CPU) is provided for controlling an operation of the gutter system to transition the gutter system from the water collection function mode to the self-cleaning function mode. The controller is configured to communicate with a mobile device (e.g., a phone or tablet) or a computer for programing and/or controlling the operation of the gutter system. The gutter system further includes an actuating mechanism, in communication with the controller, for movably operating a wall of the gutter system from a closed position to perform the water collection function mode to an open position to perform the self-cleaning function mode. For example, the actuating mechanism moves the wall from a generally horizontal position, in the closed position, to a generally vertical or angled position, in the open position, to cause debris to fall out of the gutter system. The actuating mechanism is configured to apply a vibration motion to the wall of the gutter system to assist in the removal of debris. The controller is configured to set the duration of the vibration motion applied by the actuating mechanism to the wall. The controller can also be configured to set the degree of the vibration motion applied by the actuating mechanism to the wall. A rain sensor can be provided to be in communication with the controller for signaling to the controller on when rain has stopped so that the controller can initiate the self-cleaning function mode. The rain sensor can also signal to the controller on the severity of the rain so that the controller can change a type of the self-cleaning function to be performed. For example, the controller can set the duration of the vibration or the degree of the vibration based on the detection of the rain sensor.

Thebottom walls 18 in thegutter drop segments 22 does not open and close because of the presence of gutter drops 22′.Gutter hangers 30 can be provided to further fixedly support theouter wall 18 to theinner wall 16 and/or the dwelling. To prevent debris, such as leaves and twigs, from entering thegutter drop segments 22, thegutter hangers 30 can be permeable mesh or lattice walls as best shown inFIG. 2 . While eachgutter drop segment 22 is illustrated as being surrounded by twolattice gutter hangers 30, it can be appreciated that a top lattice wall (not illustrated) can also be disposed over these side lattice walls to completely enclose or cap thegutter drop segments 22 so as to prevent any debris from clogging theelbow 24 and thedownspout 26. -
FIG. 2 is a simplified cross sectional view along the line A-A of thegutter drop segment 22. Thetrough 20 can be seen as havingwalls elbow 24 is connected to thegutter drop 22′ and extend to thedownspout 26. Alattice wall 30, used as a gutter hanger, couples theouter wall 16 to theinner wall 14. Thelattice wall 30 is not connected tobottom wall 18 of the self-cleaningtrough segments 28 so as to allowbottom wall 18 of the self-cleaningtrough segments 28 to open and close for self-cleaning of thegutter system 10. In some embodiments, thelattice wall 30 can be connected to thebottom wall 18 of thegutter drop segments 22. In an embodiment, there can be a nominal gap between thelattice wall 30 and thebottom wall 18 so as not to interfere with the opening and closing of thebottom wall 18 of the self-cleaningtrough segments 28 during the cleaning operation and allow water to move more freely. - Referring back to
FIG. 1 , anactuating mechanism 32 is provided against anend cap 21. Theactuating mechanism 32 can also serve as an end cap. Theactuating mechanism 32 serves to rotate ashaft 34 both clockwise and counterclockwise. Theshaft 34 can extend along the length of thetrough 20 and can be supported by bearings (not shown) disposed in thegutter hangers 30 and/or along theinner wall 14. Theshaft 34 is configured to turncams 36 positioned in each of the self-cleaningtrough segments 28. The turning of thecams 36 allow thebottom wall 18 of thetrough 20 of the self-cleaningtrough segments 28 to open and close.FIG. 1 shows threecams 36 since one is needed for eachbottom wall 18 of the self-cleaningtrough segments 28. - The function of the
cams 36 is more clearly illustrated inFIGS. 3A and 3B .FIGS. 3A and 3B are the cross-sectional views of the self-cleaningtrough segment 28 along the line B-B ofFIG. 1 .FIG. 3A shows the self-cleaningtrough segment 28 in a closed position, which functions to collect rain water and divert the rain water to thegutter drop segment 22.FIG. 3B shows the self-cleaningtrough segment 28 is an open position, which functions to clean thegutter system 10. Thebottom wall 18 is connected to theinner wall 14 by abiased hinge 38. Thehinge 38 naturally biases thebottom wall 18 upwards, as shown by the arrow inFIG. 3A . This allows thetrough 20 to be water tight during collection of rainwater. Thecam 36 is in a rest or up position and is placed in a location so as not to interfere with the rainwater entering the trough 20 (for example it is positioned against theactuating mechanism 36 or the lattice walls 30). As best illustrated byFIG. 3B , theactuating mechanism 32 turns theshaft 34, causing thecam 36 to turn (here counterclockwise) and push against thebiased bottom wall 18. The arrows inFIGS. 3A and 3B illustrate the movement of thecam 36. Thebottom wall 18 is pushed opened by thecam 36, to allow debris, such as twigs and leaves, to fall out. When in this open position, theactuating mechanism 32 can vibrate thecam 36 for vigorously vibrating thebottom wall 18. Theouter wall 16 andinner wall 14 can also shake as a result of this vibration action. The vibration allows thebottom wall 18 to shake the debris that may be stuck to thetrough 20. Once the cleaning function is completed, the actuating mechanism turns the cam from the down, open position back to its rest or up position (here clockwise). Thebottom wall 18 self-biases upwards to its closed position, ready to collect rainwater. Thebottom wall 18 can be described as being in a generally horizontal position at the closed position and a generally vertical or angled position at the open position. Thebottom wall 18 can also include alip 40 so as to overlap theouter wall 16 and form a tighter seal against theouter wall 16 when in the closed position. - The
gutter system 10 thus has a water collection function mode for collecting and diverting water during rain and can transition or changeover to a self-cleaning function mode for cleaning debris, such as twigs, leaves, and dirt after the rain has ended. As will be described below, theactuator mechanism 32 includes a motor (inside the device) to operating thecams 36, a power unit (rechargeable batteries), a controller for controlling the motor, and a rain sensor for signaling to the controller to change the gutter system from the water collection function mode to the self-cleaning function mode. The controller of theactuator mechanism 32 can also be in communication (e.g., via Bluetooth® connection) with a user system or interface, such as a computer or mobile device (e.g., smart phone or tablet) to allow a user to program or control the operation of thegutter system 10. The user can initiate the self-cleaning function mode or pre-program theactuator mechanism 32 on when to start and stop the self-cleaning function mode (e.g., 1 hour after the rain has stopped, 2 hours after the rain has stopped, every other Sunday at 9 AM, etc.). The user can also program the duration of the cleaning function, the duration of the vibration function, and the degree of the vibration function, and all such functions based on the severity of the storm. For example, if it rains over an hour or if the storm is more severe, the user can program a longer vibration time and greater vibration amount as compared to shorter or less torrential rain falls. The user can also manually assisting with cleaning of thetrough 20 when thebottom wall 18 is open, such as, for example with a power hose or a broom type device. -
FIGS. 4, 5A, and 5B illustrate another embodiment of the dwelling water drainage system comprising thegutter system 10. Thegutter system 10 includes a waterdiversion extension wall 42 placed between thetrough 20 and theroof 12. As a result, thetrough 20 is positioned at a distance away from the dwelling as opposed to its normal position of being abutted against the dwelling. The width w of theextension wall 42 can be from 3 to 6 inches, preferably around 3 to 4 inches. Thetrough 20 can be connected to the dwelling by thegutter hangers 30 or other types of support structure. The gutter hangers 30 can be connected to theouter wall 16 andinner wall 14 and bolted to the dwelling. The number ofgutter hangers 30 used will obviously depend on the length of thetrough 20 asenough hangers 30 need to be used to make thetrough 20 sturdy. Theextension wall 42 is sloped at a downward angle from theroof 12 towards theinner wall 14, for example at about 1 to 4 degrees, preferably at 2 to 3 degrees, to allow water to efficiently flow into thetrough 20. Theinner wall 14, as best illustrated inFIG. 5A , includes anextension portion 14′. Theextension portion 14′ has to extend above theextension wall 42 when theextension wall 42 is in its closed position—that is, the position for diverting water into thetrough 20. Preferably theextension portion 14′ should extend 1 to 3 inches above the upper surface of theextension wall 42 when at its closed position. Theextension portion 14′ of theinner wall 14 is porous or made from a lattice structure so as to prevent debris from entering thetrough 20. Gutter drops 22′ are provided in thetrough 20 to collect the water into the elbow and out the downspout. - Here, the
actuating mechanism 32 turns or rotates theextension wall 42 from a closed position (FIG. 5A ) for diverting water into thetrough 20 to an open position (FIG. 5B ) for allowing debris to fall out.FIGS. 5A and 5B are simplified to show free floatingtrough 20, but it is noted that gutter hangers 30 (or other support structures including the actuating mechanism itself) can be used to secure thetrough 20 to the dwelling. In the open position, theextension wall 42 turns downwards and away from thetrough 20 and towards the dwelling. In the open position ofFIG. 5B , theactuating mechanism 32 can further vibrate theextension wall 42 to allow the debris, which may be stuck to theextension wall 42, to be shaken off theextension wall 42. In the open position, a user can further use a power hose or extended broom to clean thegutter system 10. Thegutter system 10 thus has a water collection function mode for collecting and diverting water during rain and can transition or changeover to a self-cleaning function mode for cleaning debris, such as twigs, leaves, and dirt after the rain has ended. Theactuator mechanism 32 can include a motor (inside the device) for turning or rotating theextension wall 42, a power unit (rechargeable batteries), a controller for controlling the motor, and a rain sensor for signaling to the controller to change the gutter system from the water collection function mode to the cleaning function mode. The controller of theactuator mechanism 32 can also be in communication (e.g., Bluetooth® connection) with a user system or interface, such as a computer or mobile device (e.g., smart phone or tablet) to allow a user to program or control the operation of thegutter system 10. The user can initiate the cleaning function mode or pre-program theactuator mechanism 32 on when to start and stop the cleaning function mode (e.g., 1 hour after the rain has stopped, 2 hours after the rain has stopped, every other Sunday at 9 AM, etc.). The user can also program the duration of the cleaning function, the duration of the vibration function, and the degree of the vibration function, and all such functions based on the severity of the storm. For example, if it rains over an hour or if the storm is more severe, the user can program a longer vibration time and greater vibration amount as compared to shorter or less torrential rain falls. The user can also manually assisting with cleaning of thetrough 20 when thebottom wall 18 is open, such as, for example with a power hose or a broom type device. - In some embodiments, instead of a cam system, the
actuator mechanism 32 ofFIG. 1 can be connected directly to thebottom wall 18 and function the same way as that ofFIG. 4 with theextension wall 42. In other words,multiple actuating mechanisms 32 can be installed and be directly connected to thebottom wall 18 for turning each of thebottom walls 18 of the self-cleaningtrough segments 28. -
FIG. 6A illustrates one embodiment of theactuating mechanism 32. Themechanism 32 is configured to rotateshaft 34 for turning thecam 36.Solar cells 44 can be provided on top of theactuating mechanism 32 for recharging the power unit. Theactuating mechanism 32 can also be connected to an electrical line. Further, arain sensor 46 can be provided to sense if rain has stopped so as to signal to the controller to initiate the cleaning function. Therain sensor 46 can also detect the severity of the rain fall so that the controller can select the duration of the cleaning operation, duration of the vibration function, and the severity of the vibration function.FIG. 6B illustrates asimilar actuating mechanism 32 for operating theextension wall 42. Theactuating mechanism 32 can turn theextension wall 42 along an axis that is close to theroof 12 of the dwelling. In one embodiment, the axis of ration can be about the middle of theactuating mechanism 32 orextension wall 42. This way, when theextension wall 42 is rotated to an open position for the cleaning process, both sides of theextension wall 42 will be exposed and easily accessible. A controller (e.g., CPU) can control the function of theactuating mechanism 32 and the motor via a mobile device or computer. As shown inFIG. 7 , the controller is in communication with a motor of theactuating mechanism 32 and thesensor 46. The controller can be programed or operated by the user system/interface, such as a mobile device (iPhone or tablet) or a computer. For ease of use, the user system/interface can provide pre-set functions for the user to select or the user can manually input the time for the cleaning function, the duration of the cleaning function, the duration of the vibration, and the degree of the vibration that is to be applied. - One having ordinary skill in the art will readily understand that inventions as described above may be practiced with elements and configurations which are different than those described above. For example, the
bottom wall 18 or the extension wall may be opened and closed manually by an elongated stick with a loop and hook type system. Therefore, although the inventions have been described based upon these preferred embodiments, it would be apparent to those skilled in the art that certain modifications, variations, and alternative constructions would be apparent while remaining within the spirit and scope of the inventions.
