The present invention relates to dryers generally, and more particularly, in one embodiment, to a razor blade dryer having a chamber for holding a razor blade, a dryer for removing moisture from the blade, a sanitizer for cleaning the blade, and a vacuum for removing air from the chamber for preserving the dried and sanitized blade and inhibiting oxidation on the blade.
Wet shaving razors come in several types including the disposable type (with single or multiple blades) or of the type using disposable blades. All such shaving razor's blades generally become dull and undesirable for use (or unusable) after several uses. The dullness of the blade is caused by several mechanisms. One mechanism is the actual abrasive effect of the blade cutting through hairs and rubbing against skin. Repeated use of a razor over time inevitably produces this dulling effect.
A second mechanism that results in effective dulling (or equivalent degradation of effectiveness) of the razor blade is corrosion of the blade surface and cutting edge caused by oxidation that occurs when a wet blade is left to air dry. This occurs primarily after shaving when the wet blade is stored away until the next use. However, depending on the storage location of the blade, such as on a bathroom counter or in a shower, which are both high humidity environments, the blade can be exposed to additional sources of ambient moisture that results in the re-wetting of the blade followed by a subsequent drying. Thus, a razor blade may experience many wet-dry cycles during the day, which can accelerate the degradation of the blade over time.
While the closeness and effectiveness of a shave appears to a user to degrade with repeated use of a razor blade over time, it has been determined that the second mechanism relating to oxidation results in the most actual damage to the blade. Dryers for razor blades are known in the art and generally focus on the drying of a blade immediately after use. However, such prior art dryers fail to address environmental moisture buildup that promotes oxidation during periods when the razor blade is being stored or is otherwise exposed to moisture that is unrelated to the act of shaving.
A hygienic razor blade dryer is provided that comprises a housing having an interior, a razor blade holder disposed within the interior that is adapted to receive a razor blade, a dryer for drying a razor blade received in the razor blade holder, and a vacuum for evacuating the air within the interior to prevent moisture buildup in the air and on the razor blade and to inhibit oxidation on the blade surfaces. A sanitizer light and/or spray may also be provided to sanitize and disinfect the razor blade before, during or after the dryer operation.

The device 550 further comprises an interior 800 that is defined between the housing 600 and the door 700. The interior 800 is exposed when the door 700 is in the open position (
The interior 800 further comprises a front housing 805 having a wall 810, a razor holder mount 820 provided in the wall 810, a rear housing 825 including dryer 830 with directional blades 834, a sanitizing light 840 such as an ultraviolet (UV) light, a vent 855 for the removal of air from the interior 800, a sanitizing spray 860 in communication with a nozzle 862 adjacent the vent 855 for delivery a spritz or a spray to a razor head (not shown) positioned adjacent the vent 855. The sanitizing spray 860 may deliver a mist of alcohol or other antiseptic through the nozzle 862. The dryer 830 could be provided with a heating element (not shown) if desired. A vacuum pump 850 disposed in the rear housing 825 is in fluid communication with the vent 855 in the interior 800 for purposes of evacuating the air from within the interior 800 when so desired and as described below. The powered components of the device 550 are controlled by a CPU (not shown, but see
The razor blade holder 812 has gripping arms 814 that are dimensioned to receive the handle of a razor (now shown) or other instrument. The gripping arms 814 are flexible and resilient to allow for easy insertion and removal of a razor therefrom, and such arms 814 are spaced to accommodate most commonly dimensioned razor handles. In one embodiment, the razor blade holder 812 is fixedly attached to the wall 810. In an alternative embodiment, the razor blade holder 812 is removably attached to the wall 810 to allow for easy replacement or to allow for the attachment of interchangeable razor blade holders (not shown) of various dimensions for holding razors (not shown) of varying dimensions. In one embodiment, the device 550 could be provided with a variety of interchangeable holders (not shown) and the user would be required to select the holder that most comfortably fits whatever implement will be placed therein.
The razor blade holder 812 resides below the dryer 830 and the sanitizer light 840 so that the blade from a razor will be adjacent the dryer 830 and sanitizer 840 if the razor is positioned upright in the holder 812. While the vent 855 is shown in a certain location, it will be appreciated that it may be positioned anywhere within the interior 800 as long as it functions to remove air from within the interior 800 when desired. In one embodiment, the interior could be provided with multiple dryers and sanitizers (not shown) to account for the various positioning of the razor relative to the razor holder. In another embodiment, the dryer and sanitizer could reside on the door interior 720. Other arrangements are contemplated.
The housing 600 preferably comprises a switch 632 for activating the device 550 as will be described below and one or more indicators 634 for displaying a variety of operational parameters and functions including, but not limited to, power capacity of the power source 900 and the amount of sanitizing spray 860 remaining and whether the spray 860 should be replaced. This modular design of the housing 600 as shown in
One non-limiting embodiment of an operation of the device 550 of
The drying operation can be carried out in a number of ways. In a preferred embodiment, activation of the switch 632 energizes the dryer 830 in accordance with a timer that that is controlled by a central processing unit (CPU) control system such as a processor or printed circuit board (PCB) provided in the housing 600. In a preferred embodiment, the drying of the blade is accomplished by a flow of air created by the fan 830 for a certain period of time such as, but not limited to, approximately three minutes, which flow of air is drawn across the blade and evacuated through the vent 855 into the environment outside of the device 550. Based on a number of environmental factors, such as the relative humidity and temperature of the surroundings, the fan operation may range, for example, from about two minutes to about ten minutes. Other drying times are contemplated. In other embodiments, a heater element (not shown) such as a resistive heating element is incorporated into the fan airstream to heat and dehumidify the blown air or otherwise accelerate the drying operation and reduce the drying time. In an alternative embodiment, the drying operation may be controlled by a humidity sensor (not shown) that evaluates the relative humidity in the interior 800 and terminates the drying operation once a certain humidity level is reached.
In a preferred embodiment, the sanitizer light 840, such as an ultraviolet (UV) light, is also activated during the drying operation. In an alternative embodiment, the sanitizer light is activated after the drying operation is complete. The sanitizing spray 860 may also be applied manually by the user or automatically as part of the operation of the device 550 during the drying and sanitizing operation for example. For example, activation of the switch 632 while the door 700 is open and a razor is engaged in the holder 812 may cause the delivery of a spritz of sanitizing spray 860 without an accompanying heating operation. The purpose of any cleaning solution is to remove any oils or salts that remain on the blades after being used and to lubricate the blades, while the sanitizer light is used to kill any bacteria remaining on the blades.
The drying operation is preferably controlled by a timer or a humidity sensor or both. Depending upon the amount of air flow and heat generated, if any, the time for the drying operation can be determined experimentally to provide a suitable level of drying of the razor blade. During or after the drying operation, the vacuum pump 850 evacuates air and moisture through the vent 855 and out of the interior 800 and seals the interior 800 in order to maintain a dry and suitable environment for the stored razor and to prevent oxidation at the blades until it is desired to use the razor again. If a humidity sensor is employed, the drying operation may automatically repeat without user intervention if the relative humidity within the vacuum-sealed interior 800 reaches a certain level. A valve (not shown) is provided to maintain a vacuum seal within the interior 800 once a sufficient amount of air has been evacuated. In one embodiment, pressing of the switch 632 with a vacuum in the interior 800 acts to release the vacuum and enable the user to open the door 700. In another embodiment, a separate button (not shown) could be used to release the vacuum seal, or it can occur simply by disengaging the latch 660.
A display (not shown) may be incorporated in the housing 600 and various parameters may be indicated on such display, such as the time of day, the ambient temperature, whether an implement is being retained by the holder 812, the time duration of the drying operation, the amount of time left in the drying operation, whether the sanitizer light 840 is activated, whether the sanitizer spray 860 is almost empty, whether the vacuum 850 is activated, the relative humidity within the interior 800, whether the interior 800 is vacuum sealed, and whether the device 550 is either turned off or not active. The display may also show whether the device 550 is connected to an external power source such as home current, or whether the device 550 is running on battery power 900 and the amount of battery life remaining. Other operational parameters are contemplated.
The device of the present invention can be constructed in several different price points. For example, a baseline economy version may not include a sanitizer light, vacuum pump or a display and may simply include a dryer that activates with the push of a single switch for a predetermined period of time. The next level up may include a sanitizer spray and sanitizer light that is activated along with the dryer. The next level up may include a humidity sensor that automatically triggers the dryer when the relative humidity reaches a certain level in the interior, and a display for monitoring the same. The next level up may include a vacuum pump in combination with a dryer and a sanitizer light and spray.
