The present subject matter relates generally to dryer appliances, or more specifically, to systems for delivering a clothing treatment fluid from a reservoir to the drying chamber.
Dryer appliances generally include a cabinet having a rotating drum with a chamber therein to permit drying of articles of clothing. Demand for the ability to treat clothing with various desirable or protective liquids is rising. In particular, demand for the ability to introduce a scent to dry clothing is growing. Additionally, there is a demand to treat dry clothing with various protective coatings, such as with liquids providing ultraviolet light protection, anti-microbial liquids, or other medicinal fluids.
Conventionally, clothing is treated, for example with stain removers and the like, prior to washing. However, this method is ineffective for treating cloths with scent, ultraviolet protection, anti-microbial protection, and other similar medicinal fluids because washing the clothes will remove the intended application. Such treatments must be applied to dry clothing after the washing cycle is complete. Currently, the application of such fluids would not involve the use of a dryer, but would instead be done manually on each item of clothing individually, resulting in a large investment of time and treatment materials.
Accordingly, a dryer appliance capable of applying a scent or other fluid to coat dry clothing is desirable.
Advantages of the invention will be set forth in part in the following description, or may be apparent from the description, or may be learned through practice of the invention.

Dryer appliance 10 defines a vertical direction V, a lateral direction L, and a transverse direction T. The vertical direction V, lateral direction L, and transverse direction T are mutually perpendicular and form an orthogonal direction system. Cabinet 12 includes a front panel 14 and a rear panel 16 spaced apart along the transverse direction T, a side panels (not shown) spaced apart along the lateral direction L, and a bottom panel 22 and a top surface 24 spaced apart along the vertical direction V. Within cabinet 12 is a container or drum 26 which defines a chamber 28. Chamber 28 defines a front opening 29 for receipt of articles, e.g., clothing, linen, etc., for drying. Drum 26 extends between a front portion and a back portion, e.g., along the transverse direction T. In example embodiments, drum 26 is rotatable, e.g., about an axis that is parallel to the transverse direction T, within cabinet 12. Rotation of drum 26 is driven by a motor (not shown). A door 30 is rotatably mounted to cabinet 12 for providing selective access to drum 26. Door 30 rotates between an open position and a closed position. When in the closed position, door 30 covers front opening 29.
As best shown in
Drum 26 may be configured to receive heated air that has been heated by a heating assembly in order to dry damp articles disposed within chamber 28 of drum 26. Heating assembly 50, as further described below, includes a heater housing 54 that is in fluid and thermal communication with chamber 28. A heater 52 may be at least partially disposed within heater housing 54 (see
Within chamber 28, the heated air can remove moisture, e.g., from damp articles disposed within chamber 28. This internal air flows in turn from chamber 28 through an outlet assembly positioned within cabinet 12. The outlet assembly generally defines an air exhaust passage 34 and includes a trap duct (not shown), air handler 32, and an exhaust conduit 62. Exhaust conduit 62 is in fluid communication with the trap duct via air handler 32. During a dry cycle, internal air flows from chamber 28 through the trap duct to air handler 32, e.g., as an outlet flow portion of airflow. As shown, air further flows through air handler 32 and to exhaust conduit 62.
The internal air is exhausted from dryer appliance 10 via exhaust conduit 62. In some embodiments, an external duct (not shown) is provided in fluid communication with exhaust conduit 62. For instance, the external duct may be attached (e.g., directly or indirectly attached) to cabinet 12 at rear panel 16. Any suitable connector (e.g., collar, clamp, etc.) may join the external duct to exhaust conduit 62. In residential environments, the external duct may be in fluid communication with an outdoor environment (e.g., outside of a home or building in which dryer appliance 10 is installed). During a dry cycle, internal air may thus flow from exhaust conduit 62 and through the external duct before being exhausted to the outdoor environment.
In exemplary embodiments, trap duct may include a filter portion which includes a screen filter or other suitable device for removing lint and other particulates as internal air is drawn out of chamber 28. The internal air is drawn through the filter portion by air handler 32 before being passed through exhaust conduit 62. After the articles have been dried (or a drying cycle is otherwise completed), the articles are removed from drum 26, e.g., by accessing chamber 28 by opening door 30. The filter portion may further be removable such that a user may collect and dispose of collected lint between drying cycles.
One or more selector inputs 80, such as knobs, buttons, touchscreen interfaces, etc., may be provided on a front control panel 82 and may be in communication with a processing device or controller 84. Signals generated in controller 84 operate the motor, heating assembly 50, and other system components in response to the position of selector inputs 80. Additionally, a display 86, such as an indicator light or a screen, may be provided on front control panel 82. Display 86 may be in communication with controller 84 and may display information in response to signals from controller 84.
As used herein, “processing device” or “controller” may refer to one or more microprocessors or semiconductor devices and is not restricted necessarily to a single element. The processing device can be programmed to operate dryer appliance 10. The processing device may include, or be associated with, one or more memory elements (e.g., non-transitory storage media). In some such embodiments, the memory elements include electrically erasable, programmable read only memory
(EEPROM). Generally, the memory elements can store information accessible processing device, including instructions that can be executed by processing device. Optionally, the instructions can be software or any set of instructions and/or data that when executed by the processing device, cause the processing device to perform operations. For certain embodiments, the instructions include a software package configured to operate appliance 10 and execute certain cycles or operating modes.
In addition, dryer appliance 10 may generally include an external communication system which is configured for enabling the user to interact with dryer appliance 10 using a remote device. Specifically, according to an exemplary embodiment, the external communication system is configured for enabling communication between a user, an appliance, and a remote server. According to exemplary embodiments, dryer appliance 10 may communicate with a remote device either directly (e.g., through a local area network (LAN), Wi-Fi, Bluetooth, etc.) or indirectly (e.g., via a network), as well as with a remote server, e.g., to receive notifications, provide confirmations, input operational data, transmit sound signals and sound signatures, etc.
In general, a remote device may be any suitable device for providing and/or receiving communications or commands from a user. In this regard, the remote device may include, for example, a personal phone, a tablet, a laptop computer, or another mobile device. In addition, or alternatively, communication between the appliance and the user may be achieved directly through an appliance control panel. In general, the network can be any type of communication network. For example, the network can include one or more of a wireless network, a wired network, a personal area network, a local area network, a wide area network, the internet, a cellular network, etc. In general, communication with network may use any of a variety of communication protocols (e.g., TCP/IP, HTTP, SMTP, FTP), encodings or formats (e.g. HTML, XML), and/or protection schemes (e.g., VPN, secure HTTP, SSL).
An external communication system is described herein according to an exemplary embodiment of the present subject matter. However, it should be appreciated that the exemplary functions and configurations of an external communication system provided herein are used only as examples to facilitate description of aspects of the present subject matter. System configurations may vary, other communication devices may be used to communicate directly or indirectly with one or more appliances, other communication protocols and steps may be implemented, etc. These variations and modifications are contemplated as within the scope of the present subject matter.
In some embodiments, dryer appliance 10 also includes one or more sensors that may be used to facilitate improved operation of dryer appliance. For example, dryer appliance 10 may include one or more temperature sensors which are generally operable to measure internal temperatures in dryer appliance 10 and/or one or more airflow sensors which are generally operable to detect the velocity of air (e.g., as an air flow rate in meters per second, or as a volumetric velocity in cubic meters per second) as it flows through the appliance 10. In some embodiments, controller 84 is configured to vary operation profiles of heating assembly 50 based on one or more temperatures detected by the temperature sensors or air flow measurements from the airflow sensors.

As previously discussed, dryer appliance 10 further includes a fluid distribution path 130 for directing the treatment fluid from reservoir 120 to fluid distribution element 140. Fluid distribution path 130 may take the form of a hose, conduit, pipe, or other similar fluid communication means. Fluid distribution path 130 may have a first end 132 and a second end 134. First end 132 of fluid distribution path 130 may be connected to reservoir 120 to permit treatment fluids to flow from reservoir 120 into fluid distribution element 130. In the embodiment of
Referring again to
As previously explained, fluid distribution element 140 may deposit treatment fluid directly onto heater 52. However, it is to be expected that, over time and depending on the nature of the treatment fluid, residue may accumulate on heater 52 and maintenance and cleaning would be difficult in light of the inaccessibility of heater 52 within dryer appliance 10. Therefore, in certain embodiment, it may be desirable to add an intermediate layer between the treatment fluid and heater 52. As shown in the embodiment of
Once treatment fluid is deposited with heating assembly 50, heater 52 evaporates the treatment fluid. The gaseous treatment fluid then mixes with the ambient air drawn through heating assembly 50 as previously described. The mixture passes through an opening 200 in cabinet 12 (
