Additionally, the interior cavity 34 of the laundry chemistry dispenser 14 may be divided by a partition 88 to define the first, second, and third dispenser bodies 70a, 70b, 70c. Although three dispenser bodies 70a-70c are illustrated, it is generally contemplated that less than three or more than three dispenser bodies 70a-70c may be used when forming the laundry chemistry dispenser 14. Moreover, the partition 88 may divide the interior cavity 34, such that two or more interior cavities 34 are defined. For example, the laundry chemistry dispenser 14 is divided by the partition 88 to define three interior cavities 34a-34c. It is generally contemplated that the first interior cavity 34a may be used for dispensing the laundry chemistry 72, while the second and third interior cavities 34b, 34c may be used for dispensing other liquids such as fabric softener and/or bleach. The sidewalls 38, the partition 88, and the base 18 of the dispenser body 70 define the second interior cavity 34b of the second dispenser body 70b. Within the second dispenser body 70b, a port 90 may be positioned on the base 18 and may include a tab 92 inwardly extending into the interior cavity 34b of the second dispenser body 70b for measuring a maximum amount of liquid to be dispensed. The port 90 may be used to dispense, for example, fabric softener. Each of the dispenser bodies 70 may receive the laundry chemistry 72. For illustrative purposes, not limitation, the laundry chemistry 72 dispensed in the first dispenser body 70a is typically a laundry detergent. In addition, for illustrative purposes, not limitation, the first dispenser body 70a is described in more detail and referred to generally throughout as the dispenser body 70; however, each dispenser body 70 (the first, second, or third dispenser bodies 70a, 70b, 70c) may include the same general features described in association with the first dispenser body 70a. Additionally, an outlet 94 is positioned proximate the lower portion 74 of the dispenser body 70. The base 18 of the dispenser body 70 is shown as generally sloped and/or angular toward the outlet 94 to provide a flow path for a liquid received in the dispenser body 70. In addition, the upper portion 68, the sidewalls 38, and the flanges 62 of the dispenser body 70 define an upper opening 76. The inlet 66 (
Referring now to
As noted above, the laundry chemistry 72 generally includes components that have a hydrophilic tendency, such that the laundry chemistry 72 is inclined to bond with the liquid supplied to the dispenser body 70 through the inlet 66. Accordingly, the laundry chemistry 72 is more inclined to stick to portions exposed to the liquid dispensed through the inlet 66. Moreover, the laundry chemistry 72, with the hydrophilic components, is more likely to be attracted to wet clothing that may be in the appliance 10. This attraction allows the laundry chemistry 72 to clean the clothing in the appliance 10. Due to the hydrophilic nature of the laundry chemistry 72, the coating 42 may be provided on surfaces of the dispenser body 70 where contact with the laundry chemistry 72 is intended. Without the coating 42, the laundry chemistry 72 will partially adhere to the base 18 and the sidewalls 38 of the dispenser body 70, which would eventually create a build-up of laundry chemistry 72 within the dispenser body 70. The dispenser body 70 will get wet from the liquid dispensed through the inlet 66, which would otherwise attract the laundry chemistry 72. However, the coating 42 allows the dispenser body 70 to repel the laundry chemistry 72 in order to minimize potential build-up of the laundry chemistry 72.

Additionally, the carbon nanotube-based coating 42 blended with zinc oxide nanoparticles exhibits superhydrophobicity features where multiwalled carbon nanotubes may influence the performance of the coating 42, such as improved adhesion strength, increasing wear resistance, and overall impedance enhancement. It has been found that oxygen and water are a main factor causing metal materials to corrode. Therefore, a unique formulation of the superhydrophobic coating 42 has been developed to offer improved non-wetting features with high performance, such as easy rolling of water droplets from the surface. Traditionally pure nano-zinc oxide is hydrophilic due to the many hydroxyl groups existing on the surface of the pure nano-zinc oxide. Modification of the nano-zinc oxide particles with stearic add to obtain the hydrophobic nano-zinc oxide are provided to construct a fluorinated polysiloxane nano-zinc oxide nanocoating for use with the present concept.
More generally, the coating 42 is formed from a hexagonal nanocoating 126 that is further formed from a ceramic nanoparticle compound that includes special additives. In addition, the coating 42 generally includes carbon nanotubes, such that a carbon nanotube forest is formed. The carbon nanotube forest improves the hydrophobicity of the coating 42, such that a heterogeneous surface is formed on a nano-scale. Thus, even a minuscule amount of the laundry chemistry 72 will still be repelled by the coating 42. Accordingly, the coating 42 may have either hydrophobic or superhydrophobic properties, such that a contact angle 130 between the laundry chemistry 72 and the dispenser body 70 is relatively substantial. For example, in distinguishing hydrophobic and superhydrophobic coatings, the hydrophobic coating 42 provides for a contact angle 130 of at least approximately 100-degrees. The contact angle 130 is referred to as the angle between a drop 134 of the laundry chemistry 72 and a flat and horizontal surface upon which the drop 134 is placed, for example on the base 18 of the dispenser body 70. Generally, the contact angle 130 between the hydrophobic coating 42 and the drop 134 may range from approximately 90-degrees to approximately 130-degrees. Comparatively, the superhydrophobic coating 42, provides for a contact angle 130 of at least approximately 130-degrees. Generally, the contact angle 130 between the superhydrophobic coating 42 and the drop 134 may range from approximately 130-degrees to approximately 160-degrees.
As shown in
The contact angle 130 between the laundry chemistry 72 and the dispenser body 70 increases as the level of hydrophobicity of the coating 42 increases. This measurement of hydrophobicity is also known as wetting, which may be defined as how a liquid deposited on a substrate spreads out, or the ability of the liquid to form a boundary with the substrate. For example, the drop 134 of laundry chemistry 72 dispensed onto the base 18 of the dispenser body 70 forms a boundary in response to the hydrophobicity of the coating 42. The laundry chemistry 72 is repelled by the coating 42 and minimally spreads out relative the base 18, such that the drop 134 remains in a bead-like configuration. Accordingly, as the contact angle 130 increases there is a smaller contact point 132 between the laundry chemistry 72 and the coating 42, such that the highest level of hydrophobicity would result in a single contact point 132 of the laundry chemistry 72 contacting the coating 42 to form the drop 134. Having a diminished area of contact, the drop 134 will ultimately roll along the coating 42 until it passes through the outlet 94 and into a washtub 142 (
The coating 42 applied to the dispenser body 70 provides for a large contact angle 130 between the coating 42 and the laundry chemistry 72, such that the coating 42 is at least hydrophobic. The laundry chemistry 72, when in contact with the coating 42, will minimize contact with the surface of the dispenser body 70 and instead will condense to form compact drops 134 in order to minimize the surface area 112. Thus, the drops 134 of the laundry chemistry 72 will have a generally spherical shape resulting in the drops 134, at least partially, rolling relative the coating 42. Where the coating 42 is superhydrophobic, the drops 134 of the laundry chemistry 72 will roll relative the coating 42, in that the laundry chemistry 72 will not stick to the coating 42. Consequently, a sliding angle 150 of the laundry chemistry dispenser 14 is improved by applying the coating 42. The sliding angle 150 measures the level of resistance of a substance to a particular liquid, such that the smaller the sliding angle 150 the more repellant the surface of the substance. Typically, the sliding angle 150 is defined by the angle between a surface (e.g., the dispenser body 70 and/or the coating 42) and a liquid drop (e.g., the drop 134 of laundry chemistry 72) at which the liquid drop starts to slide off the sample surface under the influence of gravitational force. As illustrated in
When the laundry chemistry 72 is dispensed into the washtub 142, the laundry chemistry 72 is typically mixed with water, which further increases the sliding angle 150 between the laundry chemistry 72 and the hydrophobic or superhydrophobic coating 42. The laundry chemistry 72 generally has a high viscosity, which is lessened by the mixture of water with the laundry chemistry 72. The mixture of the water and the laundry chemistry 72 improves the liquid flow, such that the mixture is more likely to be easily dispensed from the laundry chemistry dispenser 14. Moreover, as the water mixes with the laundry chemistry 72 a strong bond is formed between the water and the laundry chemistry 72 as a result of the hydrophilic properties of the laundry chemistry 72.
Accordingly, the base 18 of the dispenser body 70 is slightly angled to direct the mix of water and laundry chemistry 72 out of the dispenser body 70 via the outlet 94. Stated differently, the sliding angle 150 between the laundry chemistry 72 and the base 18 of the dispenser body 70 is minimal. The coating 42 may be applied to various parts of the laundry chemistry dispenser 14, but the coating 42 is applied at least to portions in which the laundry chemistry 72 will come into contact most directly, such as the base 18, the lower portion 74 of the dispenser body 70, and the outlet 94. Additionally, due to the lower viscosity of other liquids (e.g., bleach, fabric softener, vinegar, etc.), it may be desirable to apply the coating 42 to the first dispenser body 70a and leave the second and third dispenser bodies 70b, 70c uncoated. Alternatively, to ensure maximal cleanout of the laundry chemistry dispenser 14, the coating 42 may be applied to all three of the dispenser bodies 70a-70c.
The coating 42 is formed from a hard coating formulation, such as the ceramic nanoparticle compound with special additives mentioned above, in order to minimize reactions with the additives in the laundry chemistry 72. The use of the hard coating formulation lengthens the lifespan of the coating 42. The coating 42 provides the laundry chemistry dispenser 14 with hydrophobic properties. A conventional container is generally formed from a polymeric material that alone will result in a generally small contact angle 130 between the laundry chemistry 72 and the container. Accordingly, a high sliding angle 150 is required to remove the laundry chemistry 72 from the container. Applying the coating 42 to the inner surfaces 22 of each sidewall 38 and the inner surface 22 of the base 18 results in the dispenser body 70 being fully coated with the coating 42. However, it is also contemplated that the dispenser body 70 may be partially coated, such that only the lower portion 74 of the dispenser body 70 is covered by the coating 42. For example, the dispenser body 70 includes the indication line 86 (
In conventional laundry appliances, the laundry chemistry 72 is washed out of the container in an attempt to cleanse the container of the laundry chemistry 72. However, the polymeric material of most conventional containers has a low level of hydrophobicity, such that the water used to wash out the container is not repelled by the container itself. Accordingly, some water and laundry chemistry 72 residue will stick to the container, which will result in a build-up of laundry chemistry 72 in the container. Thus, the consumer must clean the container regularly to avoid the build-up of laundry chemistry 72. If regular cleaning is not maintained then the build-up of laundry chemistry 72 will occur in the container and ultimately affect the clothes to be washed in the laundry appliance. The build-up will eventually breakdown and will be dispensed with the fresh laundry chemistry 72 during the wash cycle. As a result, the build-up will be attracted to the wet clothing due to its hydrophilic properties resulting in black spots on the clothes in the laundry appliance.
Not only are the black spots unsightly on otherwise clean clothing, but the black spots also exude an odor. Unless the build-up in the container is entirely removed, the odor-inducing black spots will continue to stain the clothes in the laundry appliance during the wash cycle. Accordingly, the use of the coating 42 prevents such build-up from occurring in the first place. Due to the hydrophilic properties of the laundry chemistry 72, it will be repelled by the hydrophobic properties of the coating 42. This repulsion is amplified once water is mixed with the laundry chemistry 72 in order to dispense the laundry chemistry 72 from the dispenser body 70 into the appliance 10. The laundry chemistry 72 is attracted to the water, and the mixture of water with the laundry chemistry 72 will further minimize contact with the dispenser body 70 because of the coating 42. Thus, when dispensing the laundry chemistry 72 from the dispenser body 70 the laundry chemistry 72 will not stick to the dispenser body 70, but rather, the coating 42 repels the laundry chemistry 72 out of the dispenser body 70 and into the washtub 142. Accordingly, the build-up is eliminated as the laundry chemistry 72, along with the water, has been removed during the washout of the dispenser body 70 by the water and aided by the coating 42. By applying the coating 42 to the laundry chemistry dispenser 14 in areas that the laundry chemistry 72 will come into contact, the clothes to be washed will not be ruined by build-up residue and an unpleasant odor, because the laundry chemistry 72 will fully washout avoiding build-up in the laundry chemistry dispenser 14.
