Abstract

A portable appliance with a housing defining a space for operating components. The operating components define an air moving mechanism for causing atmospheric air to be drawn into the housing space to at least one of: a) cool at least one of the operating components; b) be treated by at least one of the operating components; and c) cause movement of a fluid within the housing space. The housing has a first wall with a downwardly facing surface in which an inlet opening is defined through which atmospheric air is drawn into the housing space. The housing further has a spacing wall that underlies the inlet opening and bounds in conjunction with the first wall an intake space through which atmospheric air is guided in a generally horizontal path towards the inlet opening.

Claims (41)

1. A portable appliance comprising:

a housing defining a space; and

operating components in the space,

the housing having a top and bottom,

the operating components comprising an air moving mechanism for causing atmospheric air to be drawn into the housing space to at least one of: a) cool at least one of the operating components; b) be treated by at least one of the operating components; and c) cause movement of a fluid within the housing space,

the housing having a first wall with a downwardly facing surface in which an inlet opening is defined through which atmospheric air is drawn into the housing space,

the housing further comprising a spacing wall that underlies the inlet opening and bounds in conjunction with the first wall an intake space through which atmospheric air is guided in a generally horizontal path towards the inlet opening,

the portable appliance configured to be supported stably in an operative position upon an upwardly facing, subjacent support surface so that the upwardly facing, subjacent support surface underlies the inlet opening.

2. The portable appliance according to claim 1 wherein the downwardly facing surface is substantially flat and the spacing wall has a substantially flat surface that faces, and is spaced beneath, the downwardly facing surface on the first wall.

3. The portable appliance according to claim 2 wherein the downwardly facing surface on the first wall and the flat surface on the spacing wall are substantially parallel to each other.

4. The portable appliance according to claim 2 wherein the spacing wall has a peripheral edge and the intake space is defined substantially fully around the peripheral edge of the spacing wall.

5. The portable appliance according to claim 1 wherein the spacing wall is aligned to substantially fully block the inlet opening as viewed from the bottom of the housing.

6. The portable appliance according to claim 1 wherein the housing has a peripheral edge and the intake space is defined at and around at least a portion of the peripheral edge of the housing.

7. The portable appliance according to claim 1 wherein the first wall has a horizontal center and the inlet opening is located at or adjacent to the horizontal center.

8. The portable appliance according to claim 1 wherein there is a plurality of spacer elements that reside between the first wall and the spacing wall.

9. The portable appliance according to claim 1 wherein the inlet opening has a generally circular shape and the spacing wall has a portion that is curved and at least nominally conformed to the circular shape of the inlet opening.

10. The portable appliance according to claim 1 wherein the operating components produce steam and the air moving mechanism causes air to be drawn into the housing space to force movement of the steam within the housing space.

11. The portable appliance according to claim 1 wherein the operating components treat air and the air moving mechanism causes air to be drawn into the housing space to be treated by the operating components.

12. The portable appliance according to claim 1 wherein at least one of the operating components generates heat in operation and the air moving mechanism causes air to be drawn into the housing space to cool the at least one operating component that generates heat.

13. The portable appliance according to claim 1 wherein the portable appliance further comprises spacing elements on the downwardly facing surface of the first wall defining bearing surfaces that cooperatively support the portable appliance in the operative position upon an upwardly facing, subjacent support surface.

14. The portable appliance according to claim 13 wherein the bearing surfaces project further downwardly from the downwardly facing surface on the first wall than the spacing wall.

15. The portable appliance according to claim 1 wherein the spacing wall has an area that is substantially less than an area of the downwardly facing surface on the first wall.

16. The portable appliance according to claim 6 wherein the intake space is defined through less than 90° around the peripheral edge of the housing.

17. The portable appliance according to claim 8 wherein the portable appliance further comprises at least one fastener that extends through the first wall and one of the spacer elements into the spacing wall to maintain the spacing wall in place.

18. A portable appliance comprising:

a housing defining a space;

the housing having a top and bottom; and

operating components making up an air moving mechanism for causing atmospheric air to be drawn into the housing space to at least one of: a) cool at least one of the operating components; b) be treated by at least one of the operating components; and c) cause movement of a fluid within the housing space,

wherein the housing has an inlet opening through which atmospheric air is drawn vertically upwardly into the housing space,

the housing further comprising a spacing wall that underlies the inlet opening to at least partially block the inlet opening as viewed from the bottom of the housing and bound an intake space through which atmospheric air is guided in a generally horizontal path towards the inlet opening.

19. The portable appliance according to claim 18 wherein the spacing wall has a peripheral edge and the intake space is defined substantially fully around the peripheral edge of the spacing wall.

20. The portable appliance according to claim 18 wherein the housing has a peripheral edge and the intake space is defined at and around at least a portion of the peripheral edge of the housing.

21. A portable appliance comprising:

a housing defining a space; and

operating components in the space,

the housing having a top and bottom,

the operating components comprising an air moving mechanism for causing atmospheric air to be drawn into the housing space to at least one of: a) cool at least one of the operating components; b) be treated by at least one of the operating components; and c) cause movement of a fluid within the housing space,

the housing having a first wall with a downwardly facing surface in which an inlet opening is defined through which atmospheric air is drawn into the housing space,

the housing further comprising a spacing wall that underlies the inlet opening and bounds in conjunction with the first wall an intake space through which atmospheric air is guided in a generally horizontal path towards the inlet opening,

wherein the portable appliance further comprises spacing elements on the downwardly facing surface of the first wall defining bearing surfaces that cooperatively support the portable appliance on an upwardly facing, subjacent support surface,

wherein the bearing surfaces project further downwardly from the downwardly facing surface on the first wall than the spacing wall.
