Disinfecting device
View Patent ↗A sanitizing system uses ultraviolet light within a housing having an interior chamber. When items such as shopping carts or wheel chairs are moved into and out of the interior chamber, a cover is moved to reduce the light shining out of the housing. The cover is coordinated with the door of the housing to limit light shining on the users of the system. In another configuration, a switch is used to turn off the light source to reduce the light shining out of the housing when items such as shopping carts or wheel chairs are moved into and out of the interior chamber. In both of the systems described above, the sanitizing system may use a single sanitizing source such as a UV light source or a combination of sanitizing systems such as a UV light source in combination with a source of disinfecting plasma.
1. A system for sanitizing an item; the system comprising:
a housing defining an interior chamber; the housing having an opening that allows the item to be sanitized to be placed into the interior chamber of the housing;
a first source of sanitizing UV light associated with the housing; the first source providing UV light to the interior chamber of the housing;
a photohydroionization (PHI) cell used in cooperation with the UV light; and
the housing having an interior surface; the interior surface being reflective and irregular surface.
2. The system of claim 1 , wherein the sanitizing UV light is UV-C light.
3. The system of claim 1 , wherein the reflective and irregular surface interior surface of the housing is a surface of a section of aluminum tread.
4. The system of claim 1 , wherein the reflective and irregular surface interior surface of the housing is a surface of a section of diamond plate.
5. The system of claim 1 , wherein the reflective and irregular surface interior surface of the housing is a surface of a section metalized polymer material.
6. The system of claim 1 wherein the reflective and irregular surface interior surface of the housing is a surface of a section metalized corrugated material.
7. The system of claim 1 , wherein the first source of sanitizing UV light is encapsulated in a protective housing.
8. The system of claim 7 , wherein the protective housing is shatter-proof.
9. The system of claim 1 , further comprising a door having open and closed conditions; the open condition of the door allowing access to the interior chamber; the closed condition of the door limiting access to the interior chamber; and
the UV light source being turned off when the door is in the open condition.
10. A system for sanitizing an item; the system comprising:
a housing defining an interior chamber; the housing having an opening that allows the item to be sanitized to be placed into the interior chamber of the housing;
a first source of sanitizing UV light associated with the housing; the first source providing UV light to the interior chamber of the housing;
the housing having an interior surface; the interior surface being reflective and irregular surface;
a door having open and closed conditions; the open condition of the door allowing access to the interior chamber; the closed condition of the door limiting access to the interior chamber; and
a light cover that moves to a blocking position when the door is moved to the open condition; the blocking position of the light cover reducing the amount of UV light reaching the opening that defines access to the interior chamber.
11. The system of claim 10 , wherein the sanitizing UV light is UV-C light.
12. The system of claim 10 , wherein the reflective and irregular surface interior surface of the housing is a surface of a section of aluminum tread.
13. The system of claim 10 , wherein the reflective and irregular surface interior surface of the housing is a surface of a section of diamond plate.
14. The system of claim 10 , wherein the reflective and irregular surface interior surface of the housing is a surface of a section metalized polymer material.
15. The system of claim 10 , wherein the reflective and irregular surface interior surface of the housing is a surface of a section metalized corrugated material.
16. The system of claim 10 , wherein the first source of sanitizing UV light is encapsulated in a protective housing.
17. The system of claim 16 , wherein the protective housing is shatter-proof.
18. The system of claim 10 , further comprising a photohydroionization (PHI) cell used in cooperation with the UV light.
