Description

REMOTE CONTROLLABLE WASHER DRYER SYSTEM ABLE TO

AUTOMATICALLY MOVE CLOTHES FROM WASHER TO DRYER AND FROM DRYER TO OUTSIDE LAUNDRY BASKET

FIELD

[0001] The exemplary embodiment(s) of the present invention relates to cleaning equipment. More specifically, the exemplary embodiment(s) of the present invention relates to a washer and dryer machine.

BACKGROUND

[0002] A washing machine, also known as laundry machine or washer, is a machine for cleaning or laundering clothes and/or fabric articles using water. A convention washing machine could have either top loading or front loading. The top load design, for example, places the clothes in a vertically mounted perforated basket where clothes are loaded through the top of the machine, which may be covered with a door on the top of washing machine. The front loading washing machine is a horizontal-axis design allowing loading clothes through a door located at the front of the machine. To wash clothes, the clothes or fabric articles are pushed by multiple paddles inside of the drum and then dropped repeatedly until the clothes are washed and/or cleaned. Once the washing cycle or phase is completed, the washed clothes which are often wet are manually transferred to a dryer.

[0003] A dryer, also known as clothes dryer or drying machine, is an appliance for home or commercial setting used to extract moisture from washed clothes and/or other wet textiles. A conventional dryer includes a rotating drum, also known as tumbler, using heated air flow to remove moisture from wet clothes. A typical dryer is a front loading machine that allows clothes to be loaded and/or unloaded through a front door.

[0004] A drawback, however, associated with the convention washer and/or dryer is that washed clothes generally require to be manually transferred between a washer and a dryer. [0005] A conventional approach to resolve such manual transferring is to provide a combination of washer and dryer using a single drum for both washing and drying. A problem associated with the combination of washer and dryer is that it is typically small and inefficient. Another problem associated with a typical combination of washer and dryer or dryer is that the dried clothes in the dryer need to be manually moved from the dryer shortly after the clothes are dried to prevent from wrinkling. Another shortcoming is that a conventional washing machine or dryer generally does not permit remote access.

SUMMARY

[0006] This invention discloses a washer and dryer ("SWD") system that allows the consumer to load dirty laundry into the machine and receive clean dry clothes in an outside laundry basket. The process of washing the clothes, transferring the wet clothes to the dryer, and subsequently transferring the dried clothes to the outside laundry basket is done automatically. Additionally, all phases of washing and drying can be controlled remotely.

[0007] The advantages of using the SWD machine for end users or consumers are numerous. Firstly, it greatly adds to user convenience because: several manual steps have been reduced to one manual step; and providing the user with the ability to remotely control the washing drying process. Secondly, it eliminates the need for repeat washing of moldy clothes because damp clothes were left in the washer. Thirdly, there will not be any need to re-dampen and re-dry clothes because it was left too long in the dryer.

[0008] The advantages of the SWD machine for manufacturers are numerous.

Substantial benefits to the consumer, as outlined above, can be provided with small changes to the hardware, without new technical training and at a comparable price point.

[0009] One embodiment of the presently claimed invention discloses the SWD machine capable of washing clothes via self-loading and automatic transfer. For example, the embodiment of invention includes a washing drum, washing sensor, center control gate, and dryer drum. The washing drum is structured in a cylindrical shape capable of holding water for cleaning or washing clothes with a repetitive motion. The washing sensor senses the end of or completion of washing phase associated with the washing drum and generates a wash completed signal. The dryer drum which is situated adjacent to the washing drum has a washing drum access ("WDA") door wherein the WDA door is capable of opening allowing the dryer drum to receive washed clothes from the washing drum via the center control gate based on the wash completed signal. The dryer drum is able to dry the washed clothes by extracting moisture from the washed clothes. The dryer drum then transfers the dried clothes to the laundry basket.

[0026] FIG. 1 is a diagram 100 illustrating an exemplary layout of SWD machine capable of self-loading and automatic unloading for laundry clothing in accordance with one embodiment of the present invention. Diagram 100 includes a washing machine 120, dryer 122, basket 130, and wireless network tower 102. In one example, washing machine 120, also referred to as washing unit, is situated on the top of dryer 122, also known as dryer unit. Wireless communication tower 102, in one example, is coupled to portable devices 116-118 via local wireless network or Internet 108. It should be noted that the underlying concept of the exemplary embodiment(s) of the present invention would not change if one or more components (or devices) were added to or removed from diagram 100.

[0027] Washing machine or washing unit 120, in one aspect, includes a washing drum 124 configured to contain liquid (i.e., water) for washing fabric articles and/or clothing. Washing drum 124 is configured to have a front opening for receiving articles or clothing for washing or cleaning. The front opening of washing machine 120 may be covered by a front door. Washing drum 124 can also be referred to as washer drum, washing tub, tub, drum, and/or washing container used for washing clothes. To simplify the forgoing discussion, the term "washing drum" is used hereinafter. It should be noted that washing machine 120 may include other components such as a motor, inlet water hose, outlet water hose, controller, or user interfaces. In one embodiment, washing drum 124 includes a drying drum access ("DDA") door in addition to the front opening. The DDA door is used to close a discharging opening which is used to discharge or unload washed clothing from washing drum 124 to dryer 122.

[0028] The motor, not shown in FIG. 1, is an electric generator that is able to convert electrical energy to mechanical energy which may facilitate repetitive movement of washing drum 124. The inlet water hose, in one example, is used to channel liquid substance such as water or alcohol from exterior reservoir to washing drum 124 for washing operation. The outlet water hose, in one example, is used to guild waster liquid such as dirty water from washing machine 120 to exterior drainage pipe(s). The controller, which can be an electrical component containing processor and memory, is used to manage user interface between washing machine 120 and the user.

[0029] Dryer or dryer unit 122, in one aspect, includes a drum 126 with an opening

134, motor, and ventilation channel wherein the ventilation channel is used to guild moisture from drum 126 to exterior venting pipes or exterior area. Opening 134, in one example, is used for front loading which can be closed or covered by a front door mounted at the front of dryer 122. A function of dryer 122 is to extract moisture or water from washed clothes using drum 126. In one embodiment, drum 126 includes a washing drum access ("WDA") door used to cover a self-loading opening which is used to accept or receive washed clothing from washing drum 124 to drum 126 via DDA door.

[0030] In one embodiment, the SWD machine stacks washing machine or unit 120 on top of dryer or dryer unit 122 separated by a central control gate 128. Central control gate 128, in one aspect, is located at the center of the SWD machine. Central control gate 128 can open and close for facilitating function of self-loading which allows washed clothes to be automatically transferred from washing drum 124 to dryer drum 126 via the DDA and WDA doors. [0031] During washing cycle, the DDA door and WDA door are in closed condition. After the washing cycle, the DDA door of washer drum 124 and the WDA door of dryer drum 122 are aligned and opened. When central control gate 128 opens, the washed clothes are allowed to automatically drop or self-load from washer drum 124 to dryer drum 126. After self-loading, both DDA and WDA doors including central control gate 128 are closed before the dry cycle begins.

[0032] Dryer 122, in one aspect, further includes a function of automatic transferringfor transferring or unloading dry clothes from drum 126 to basket 130 via a side outlet 132. Alternatively, the mechanism of unloading dry clothes can also be accomplished via a front opening via the front loading door. In one embodiment, the unloading or transferring dry clothes from drum 126 to basket 130 can be achieved through an unloading force created by spinning speed of drum 126. Alternative, a belt conveyor can be used to facilitate moving or transferring dry clothes from drum 126 to basket 130. In yet another embodiment, a pressurized air can be used to unload dry clothes from drum 126 to basket 130. It should be noted that basket 130 is an exemplary destination location. Other destinations such as tub or space can also be used in place of basket 130.

[0033] The SWD machine, in one embodiment, also includes a wireless communication system capable of communicating with user(s) or provider(s) via network or wireless network(s). For example, the wireless communication system is able to connect to the network via network provider 104 through landline and/or wireless via tower 102. The user, for example, can access or control the SWD machine via his/her smart phone 116 or computer 118. In one example, smart phone 116 can be iPhone^® while computer 118 can be a laptop computer. A user, for instance, can turn on the SWD machine remotely via his/her mobile. Alternatively, the user can stop or monitor the progress of washing or drying cycle remotely.

[0034] An advantage of using SWD machine containing both washer function and dryer function is that it provides self-loading of wet clothes and automatic transferring of dry clothes. In addition, the SWD machine includes both washer and dryer in a single structure which allows utilizing similar parts (i.e., one set of display, motor, electronics and wheels) for small footprint, cost, space, and money.

[0035] FIG. 2 is a block diagram 200 illustrating electrical and mechanical components of SWD machine for operating auto-load-transfer or self-loading in accordance with one embodiment of the present invention. Diagram 200 includes a central control multi-chip unit ("MCU") 202, motor and power factor controller ("PFC") MCU 204, gate drivers 206-207, 3-phase inverters 208-209, motors 210-211, and washing drum 212, dryer drum 232. It should be noted that the underlying concept of the exemplary embodiment(s) of the present invention would not change if one or more components (or blocks) were added to or removed from diagram 200.

[0036] Diagram 200 illustrates a control flow of SWD to perform and manage an auto-load-transfer ("ALT") function. The ALT function, in one embodiment, includes self-loading and automatic transferring wherein self-loading is a function allowing washed clothing to be automatically loaded into a dryer drum from a washing drum. The automatic transferring refers to a function facilitating automatic transferring dried clothing from the dryer drum to a basket 130 generally located outside of the SWD. In one example, washer motor and drum 220 are located at the top portion of diagram 200 as indicated by numeral 220. Dryer motor and drum 222 are located at the bottom portion of diagram 200 as indicated by numeral 222. A center control gate 128 is situated in the center between washing drum 212 and dryer drum 232.

[0037] During an operation, after a timer of washing function is expired, the washing cycle, for example, is ended. Central control MCU 202 subsequently sends a signal to central control gate 128 to open the gate between washer and dryer. Central control MCU 202 also transmits door control signals to both washer drum 212 and dryer drum 232 for opening DDA door 214 and WDA door 234. Upon DDA door 214 and WDA door 232 are aligned, washer drum 212 opens DDA door 214 and dryer drum 232 opens WDA door 232 for facilitating self-loading. The washed clothes subsequently move or drop out of washer drum 212 via DDA door 214 and they fall into dryer drum 232 via WDA door 234.

[0038] The SWD, in one aspect, includes an auto-load sensing feature capable of sensing whether all washed clothes inside of washing drum 212 have been loaded or dropped in dryer drum 232 during the self-loading process. If washed clothes are in drum 232 via self-loading process, central control MCU 202 issues commands to close central control gate 128, DDA door 214, and WDA door 234 before the drying cycle starts. In one example, a drying timer may be activated to clock the time period for the duration of drying cycle. Upon expiration of the drying timer, dryer drum 232 will stop at a proper position to discharge dry clothes into basket 130 or an exterior area for makeup and folding.

[0039] Alternatively, a washing sensor and drying sensor could be used in place of timers. For example, when the washing sensor detects that the washing machine or washer is done with washing, the washing sensor reports the completion of washing cycle to central control MCU 202. When the drying sensor detects the clothes inside drum 232 are dry, the drying cycle ends. To sense the dryness of clothes, the drying sensor, for example, detects the current moisture level in drum 232 is at or below a predefined dry level. Once the drying sensor issues a commend indicating the clothes are dry, the automatic transferring of dried clothing from drum 232 to basket begins.

[0040] Central control MCU 202, in one example, is the brain for the washer-dryer machine in which MCU monitors and manages input and output ("IO") from a control panel, temperature setting, hall sensors, and/or controlled signals to electromechanical devices. The exemplary electrical and/or mechanical devices include, but not limited to, door locks, buzzers, water inlet valve, water outlet valve, water heater, dryer heater, and the like. A function of MCU 202 is to manage, direct, and monitor the operations of the washer and dryer.

[0041] Motor and PFC Control MCU 204, for example, has pulse-width modulations ("PWMs"), analog-to-digital converters ("ADCs"), as well as build-in communication ports used for controlling three-phase ("3-phase") motors such as motors 210-211. Gate drivers 206-207 are used to drive MOSFET and/or insulated-gate bipolar transistor ("IGBT") power switches which are used for managing drums and fan motors such as motors 210-211. The 3-phase inverters such as motors 208-209 include three single-phase inverter switches wherein each single-phase is connected to one of the three load terminals. A function of the 3-phase inverter is to drive variable-frequency applications and high power applications such as HVDC (high- voltage direct current) power transmission.

[0042] Motor 210 or 211, in one example, may be structured without brush(s) and commutator(s) for simplifying motor design. Motor 210 or 211 and PFC control MCU 204 may be configured to replace functions usually performed by the commutator as well as to properly energize windings which create needed rotations. Three-phase BLDC (Brushless DC) devices or motors generally provide excellent performance characteristics with or without positioning sensors. A benefit of using the 3-phase BLDC is that the BLDC is relatively inexpensive with relatively long lifespan. In one embodiment, motors 210-211 can be substituted with one motor which can be configured to drive, control, and manage both washer drum 212 and dryer drum 232.

[0043] The SWD machine or unit, in one embodiment, includes a wireless connectivity component which can be used to connect to other home appliances via a home network or WIFI network. A home network includes a set of connectable home appliances and intelligent devices through a wireless router or switch. The connectable home appliances include, but not limited to, washer-dryer, refrigerator, electronic oven, power outlets, lights, door lock, fire alarm, smartphone, et cetera. The smartphone may be used as a control center controlling connected home appliances and devices.

[0044] With wireless connection, the SWD machine can provide optimal washing and drying options. For example, the SWD machine can make better choices for fabric care and energy efficiency via remote monitoring. Also, monitoring cycle time and machine status can also be carried out in real-time. Furthermore, sending notification to a destination such as a user can also be performed when a cycle is finish. The SWD machine can further obtain sensed information to determine and acknowledge if rinse agent is low. To save energy and resource, the SWD machine can select more efficient dryer cycle(s) to dry clothes based on sensed information. Auto-delay laundry cycles to avoid energy peak rate(s) can be performed based on predefined information, sensed information, and/or real-time information.

[0045] In one embodiment, the SWD machine is configured to provide auto-fold feature. For example, the SWD machine can fold clothes or fabric articles to prevent clothes from wrinkling. Also, the SWD machine is configured to store folded clothes into a predefined location or closet after the dry cycle.

[0046] FIG. 3 is a block diagram 300 illustrating a cutaway view of SWD machine having a washing drum with a DDA door and a dryer drum with a WDA door in accordance with one embodiment of the present invention. Diagram 300 illustrates a washing unit 120, dryer unit 122, and central control gate 128. Central control gate 128, in one example, is situated between washing unit 120 which is placed on top of gate 128 and dryer unit 122 which is situated below gate 128. Depending on the applications, central control gate 128 may be removed or replaced for free movement of content between washing drum 302 and dryer drum 304. It should be noted that the underlying concept of the exemplary embodiment(s) of the present invention would not change if one or more components (or blocks) were added to or removed from diagram 300.

[0047] The SWD machine illustrated in diagram 300, in one embodiment, integrates a washing unit 120 and dryer unit 122 in a single machine wherein washing unit 120 is placed on top of dryer unit 122. An advantage of having washing unit 120 on top of dryer unit 122 is that the washed clothing can travel from washing unit 120 to dryer unit 122 by gravitational force. Another benefit for having washing unit 120 on top of dryer unit 122 is to save space. Depending on the applications, washing unit 120 can also be situated side-by-side with dryer unit 122 or washing unit 120 is situated below dryer unit [0048] The SWD machine, which can also be referred to as washing and drying machine or washer and dryer machine, includes washing drum 302 and dryer drum 304 wherein washing drum 302 includes a washing sensor capable of sensing washing cycle, water temperature, spinning speed, and the like. Washing drum 302, in one aspect, has a cylindrical shape configured to hold water for cleaning or washing clothes and/or flexible fabric articles using water with a repetitive motion. In one embodiment, washing drum 302 includes a DDA door 306 which is in closed position when washing drum 302 is in operation for cleaning clothes inside the drum or tub as indicated by numeral 316. To clean or wash clothes, washing drum 302, in one example, turns around a center 336 in a direction as indicated by arrow 318.

[0049] The washing sensor, not shown in diagram 300, is coupled to washing drum 302 and senses the completion or end of the washing phase(s) or cycle(s) associated with washing drum 302. The washing sensor, coupled to the central control MCU, is capable of forwarding detected or sensed information to the central control MCU. Upon receipt of sensed situation such as end of washing cycle(s), the central control MCU will provide subsequent instruction(s) or commend(s) such as aligning DDA and WDA doors 306-308, and opening DDA and WDA doors 304-306.

[0050] Dryer drum 304 is situated adjacent to washing drum 302 wherein dryer drum 304, in this embodiment, is situated below washing drum 302. Alternatively, dryer drum 304 can be placed next to washing drum 302 in a horizontal plane. Dryer drum 304, in one aspect, includes a WDA door 308 for self-loading process. For example, upon receipt of the signal of washing completed from the washing sensor, WDA door 308 can be activated to be in an open position allowing washed clothes such as clothing 330 in washing drum 302 to automatically fall or drop into dryer drum 304 via center control gate 128. Dryer drum 304 is operable by turning around a center 338 to tumble clothing 332 inside of drum as indicated by numeral 318. A function of dryer unit 122 is to extract moisture from the washed clothes. [0051] The SWD machine, in one embodiment, further includes a laundry delivery component or system capable of unloading dry clothes in dryer drum 304. For example, the laundry delivery system which is adjacent to dryer drum 304 and capable of transferring the dried clothes from dryer drum 304 to an exterior location such as a basket via the laundry delivery system via an opening at dryer drum 304.

[0052] A drying sensor, in one example, can be installed in dryer unit 122 and configured to monitor the moisture level in dryer drum 304. When the drying sensor senses the washed clothes are dried since the moisture level has reached to a predefined dry level, the dry sensor sends a signal to stop drying cycle and begin to unload the dried clothes from dryer drum 304. To properly remove or extract moisture from the wet clothing, a drying vent is used coupling to dryer drum 304 for directing the moisture away from dryer drum 304.

[0053] One advantage of using the SWD machine is that washing drum 302 and dryer drum 304 have large volume and they can also operate independently. Another advantage of using the SWD machine is that it is capable of auto-transferring dried clothes to outside of dryer drum 304.

[0054] FIG. 4 is a block diagram 400 illustrating a cutaway view of SWD machine having a washing drum and a dryer drum in open positions in accordance with one embodiment of the present invention. Diagram 400 is similar to diagram 300 except that diagram 400 illustrates an open position during a process of self-loading allowing the washed clothes to be dropped from washing drum 302 to dryer drum 304 via a self-loading opening 410. It should be noted that the underlying concept of the exemplary

embodiment(s) of the present invention would not change if one or more components (or blocks) were added to or removed from diagram 400.

[0055] Diagram 400 illustrates a self-loading or automatic loading operation in which both DDA door 306 and WDA door 308 are in open positions to create self-loading opening 410 through central control gate 128. Self-loading opening 410, in one embodiment, allows washed clothes or wet clothes 402 to drop from washing drum 302 to dryer drum 304 via a gravitational force. In one embodiment, a self-loading sensor coupled to washing drum 302 is used to determine whether all clothes 402 have been dropped or traveled to dryer drum 304. Washing drum 302, in one embodiment, is configured to agitate or shake the drum if the self-loading sensor detects that some wet clothes 402 are still attached to washing drum 302.

[0056] When all of clothes 402 arrive to dryer drum 304, WDA door 308 will close the opening of dryer drum 304 whereby dryer drum 304 begins tumble dry the clothes. After the opening of washing drum 302 is closed, washing unit 120 is ready for the next washing cycle. It should be noted that depending on the applications, central control gate 128 can be removed or reconfigured.

[0057] The SWD machine, in one embodiment, is a cleaning system utilizing liquid substance such as water, liquor, and/or chemical compounds for washing and drying clothes. The SWD machine contains washing drum 302, dryer drum 304, and washing sensor wherein washing drum 302 is configured to provide a set of variable spinning motions to clean one or more fabric objects via a stream of liquid. While the fabric object can be a piece of clothes made by a fabric material, the stream of liquid can be a stream of water, liquor, or chemical compounds. Washing drum 302 further includes a washing open which may be used by a user for manually loading dirty laundry into washing drum 302. In one aspect, DDA door 306 can be open allowing content such as clothing in washing drum 302 to travel to dryer drum 304 passing through WDA door 308 via gravity.

[0058] The washing sensor, in one example, is coupled to washing drum 302 and is configured to sense washing phases or cycles associated with washing drum 302. While washing drum 302 is coupled to a motor and/or water hose for performing a washer function, dryer drum 304 is also coupled to a motor and a vent for performing a dryer function.

[0067] FIG. 7 is a flowchart 700 illustrating a process of self-loading and automatic transferring dry clothes operated by the SWD machine to a basket in accordance with one embodiment of the present invention. At block 702, a laundry process for cleaning clothes by the SWD machine receives clothes or fabric clothing articles via an opening of a washing drum. The opening of the washing drum, which, in one aspect, can be closed by a front loading door, allows a user to manually load dirty laundry into the washing drum. In one example, the washing drum is coupled to an external hose for obtaining water for the washing cycle. Alternatively, other liquid such as liquor or chemical compound may be used in place of water.

[0068] At block 704, after activating the washing unit of the SWD machine, the washing drum creates a movement that turns around a center via a predefined speed and duration for cleaning or washing the clothes using water. In one aspect, a user can initiate the washing process via a wireless connected device. Also, the wireless connected device, such as a smart phone or computer, can also monitor laundry cycles and status via a communication network. [0069] At block 706, a washing sensor which is coupled to the washing drum detects a completion of washing cycle carried out by the washing drum. For example, the washing sensor may be used to monitor the washing cycle(s) associated with the laundry load. For instance, if the washing sensor detects that the laundry load or clothing volume is large or the load is heavy, the washing cycle is adjusted accordingly.

[0070] At block 708, upon sending a washing completing signal from the washing sensor to the dryer drum and the washing drum, the process stops the washing unit from washing operation and activates the process of self-loading. The process of self-loading, for example, transfers washed clothes from the washing drum to the dryer drum.

[0071] At block 710, to perform self-loading, the WDA door and DDA door are first aligned whereby wet or washed clothes could leave the washing drum through the DDA door and drop into the dryer drum via the WDA door.

[0072] At block 712, the SWD opens the DDA door on the dryer drum to allow the wet clothes move or travel from the washing drum to the dryer drum using a gravitational force. Upon detecting by a dryer sensor the completion of dryer cycle associated with the dryer drum based on the moisture level inside of dryer drum, the dried clothing can be pushed or repelled from the dryer drum to an external place via a dryer opening. Note that the dryer opening can either be located on the side wall of SWD machine or on the front wall of SWD machine. In one embodiment, a pressurized air stream is activated to blow or push the dry clothes from the dryer drum to an exterior basket via the dryer opening. In one aspect, a set of alignment sensors may be used to align the WDA door of dryer drum with the DDA door of the washing drum.

[0073] While particular embodiments of the present invention have been shown and described, it will be obvious to those of skills in the art that based upon the teachings herein, changes and modifications may be made without departing from this exemplary embodiment(s) of the present invention and its broader aspects. Therefore, the appended claims are intended to encompass within their scope all such changes and modifications as are within the true spirit and scope of this exemplary embodiment(s) of the present invention.
