Abstract

The invention relates to a garment sanitizing device ( 1, 31 ) comprising a housing ( 2 ), a chamber ( 4 ) within the housing to receive one or more garments ( 14 ) to be sanitized. The chamber ( 4 ) comprises a bottom wall, a top wall, and opposite first and second sides each extending from the bottom wall to the top wall. The housing contains a fan ( 6 ) and one or more heating elements ( 10 ). The at least one heating element is configured to directly heat garments within the chamber by radiation, and the fan is configured to convey air via the at least one heating element to heat the air and to convey the heated air through the chamber to additionally heat the garments by the conveyed heated air. The at least one heating element ( 10 ) is disposed proximate the first side of the chamber to heat garments ( 14 ) within the chamber from the first side of the chamber by radiation, and the garment sanitizing device is configured such that hot air heated by the at least one heating element is conveyed into the chamber from the second side of the chamber. The invention also relates to a corresponding method of sanitizing a garment.

First claim

The invention claimed is:

1. A garment sanitizing device comprising:
a housing comprising a plurality of panels,
a single chamber within the housing comprising a plurality of walls to receive one or more garments to be sanitized,
the chamber comprising a bottom wall, a top wall, and opposite first and second sides each extending from the bottom wall to the top wall, wherein one of the first and second sides of the chamber are hinged to allow access to the interior of the chamber,
the housing containing a fan and one or more heating elements,
wherein the fan is disposed in a space between a rear panel of the housing and one of said first and second sides of the chamber
wherein the at least one heating element is disposed proximate the first side of the chamber to heat garments within the chamber from the first side of the chamber by radiation,
wherein the second side of the chamber includes an air inlet,
wherein the fan is configured to convey air via the at least one heating element to heat the air and to convey the heated air into the chamber through the air inlet in the second side of the chamber to additionally heat the garments by the conveyed heated air.

2. A garment sanitizing device according to claim 1 comprising at least one air flow passage configured to guide the flow of heated air from the fan.

3. A garment sanitizing device according to claim 2 wherein the chamber comprises a plurality of walls and the housing comprises a plurality of panels, and the chamber is disposed within the housing such that the chamber walls are spaced from the housing panels such that at least one air flow passage is defined between the chamber walls and the housing panels, and the garment sanitizing device is configured such that air is circulated by the fan from the chamber, through the air flow passage and back into the chamber.

4. A garment sanitizing device according to claim 3 further comprising an airflow guide to guide air from the air flow passage into the chamber.

5. A garment sanitizing device according to claim 4 wherein the airflow guide projects from proximate a central portion of a panel of the housing.

6. A garment sanitizing device according to claim 2 wherein the chamber includes a first wall on the first side of the chamber which comprises a plurality of apertures though which air may pass when being circulated by the fan.

7. A garment sanitizing device according to claim 6 wherein the chamber includes a second wall on the second side of the chamber opposite to the first side, and wherein the second wall includes a plurality of apertures through which air may pass when being circulated by the fan.

8. A garment sanitizing device according to claim 1 wherein at least one shelf is provided within the chamber to receive garments to be sanitized, and wherein the garment sanitizing device is configured to convey the heated air through the chamber and over the shelf in a direction parallel to the plane of the shelf.

9. A garment sanitizing device according to claim 1 comprising a single heating element configured to heat garments within the chamber by radiation and also configured to heat air conveyed through the chamber by the fan.

10. A garment sanitizing device according to claim 1 further comprising a control system configured to control its operation, and one or more sensors connected to the control system and configured to detect one or more parameters within the garment sanitizing device and/or the chamber, and operation of the garment sanitizing device is controlled in dependence upon signals received from the sensor(s).

11. A garment sanitizing device according to claim 10 wherein the sensor comprises a temperature sensor, and the control system is configured to control the garment sanitizing device to operate within a temperature range within the chamber of between 50 to 120 degrees Celsius.

12. A garment sanitizing device according to claim 10 comprising a height sensor configured to determine the height of a stack of garments within the chamber, wherein the control system is configured to control the fan speed in dependence on the signal(s) received from the height sensor.

13. A garment sanitizing device according to claim 1 , wherein the housing includes a front door on one of said plurality of panels, said front door including an airflow guide having a plurality of vanes configured to guide heated air flowing from air flow passages around the outside of the chamber to converge at the front door of the housing into the front of the chamber through the second wall of the chamber.

14. A garment sanitizing device according to claim 1 , wherein said opposite first and second sides of the chamber include a plurality of apertures effectively comprising a mesh through which air may pass when being circulated by the fan.

15. A method of sanitizing a garment using a garment sanitizing device comprising a housing, a chamber within the housing to receive one or more garments to be sanitized, the chamber comprising a bottom wall, a top wall, and opposite first and second sides each extending from the bottom wall to the top wall, the housing containing a fan and one or more heating elements, the at least one heating element being disposed proximate the first side of the chamber and an air inlet disposed at the second side of the chamber, the method comprising,
placing garments within the chamber,
directly heating the garments within the chamber from the first side of the chamber by radiation from the at least one heating element, and
additionally heating the garments using heated air by activating the fan to convey air via the at least one heating element to heat the air and to convey the heated air through the chamber from the air inlet in the second side of the chamber via air flow passages around an outside of the chamber to converge at a front of the housing towards a front of the chamber to pass through the second side of the chamber to heat the garments.
