AIR VENT FOR AN APPLIANCE One of the features of this invention is to provide a moist air vent leading from the interior of the cabinet of an appliance that contains warm moist air and a convection ambient air passage having an exit between the warm moist air exit and an adjacent surface member to protect the surface member from the existing moist air.
Other features and advantages of the invention will be apparent from the following description of several embodiments thereof taken in conjunction with the accompanying drawings. Of the drawings:
FIG. 1 is a fragmentary perspective view of a kitchen cabinet containing an under-the-counter dishwasher embodying the invention.
FIG. 2 is a fragmentary front elevational view of the dishwasher portion of FIG. 1.
FIG. 3 is an enlarged fragmentary vertical sectional view along line 33 of FIG. 2.
FIG. 4 is a view similar to FIG. 2 but illustrating a second embodiment of the invention.
F IG. 5 is a fragmentary vertical sectional view through another embodiment of the invention and schematically illustrating the proper functioning of the invention.
In the embodiment of FIGS. I3 the appliance comprises a dishwasher located beneath the counter top 11 of a kitchen counter that also contains a sink 12. The dishwasher 10 is provided with an access door l3 comprising one wall thereof. Located at the top of this door is a handle I4 and a control knob 15 of the usual type for controlling the operation of the appliance.
The dishwasher I0 includes a cabinet I6 having warm moist air on the interior [7, as shown in the schematic illustration of FIG. 5. Adjacent the top of the door 13 is a console 18 preferably made of molded or extruded parts with this console being located at the top of the door and having moist air vent means I9 bounded by interior parts of the door and having an entrance 20 covered by a screen 21 for intercepting foreign materials and also for forming a water barrier during wash portions of the cycle to prevent air flow through the vent during washing. An exit opening 22 that is horizontally elongated connects vent means 19 with the exterior for venting warm moist air from the interior 17 of the cabinet to ambient. Inside each of the exit openings 22 is a ridge 3! projecting upwardly and rearwardly toward the interior of the vent 19. This ridge functions to prevent any moisture present in the passage 32 leading to exit opening 22 from draining when the door I3 is lowered to gain access to the interior 17 of the appliance I0.
Located above the exit opening 22 of the vent means 19 are surface members such as the top edge of door 13 and the counter top II which, being relatively cool, are subject to having moisture from the warm moist air 27 condense thereon. In order to prevent this condensing of moisture on surface members such as the counter top II or the top edge of the door 13 there is provided air passage means 23 in the wall or door I3 having an exit 24 located between the moist air exit 22 and the top ofthe door I3 and counter top I l.
As is illustrated schematically in the embodiment of FIG. 5 this air passage means 23 has its entrance 25 located further down in the wall 13 so that the exit 24 is above this entrance 25 as illustrated in FIG. 5. In order to provide a flow of air between the entrance 25 and the exit 24 means are provided for heating the air within the passage 23 so that the air flow will be a rising convection flow.
In the illustrated embodiments this means for heating comprises a heat-conducting partition or panel 26 between the interior I7 of the appliance and the air passage 23 so that air in the passage 23 receives heat from the interior 17. The result is that once the interior 17 becomes warm and the warm moist air is vented as indicated by the arrows 27 the heat also raises the temperature in the air passage 23 which sets up the convection flow of air as indicated by the arrows 28 to provide a barrier layer of relatively cool dry air between the exiting moist air 27 and the ad'acent surface member II.
This barrier layer 0 relatively cool dry air 28 while being cool relative to the warm moist air 27 in the interior 17 is, nevertheless, warm relative to the ambient air outside the appliance and, hence. will not tend to form objectionable visible vapors where and when the mixing of air streams 27 and 28 occurs.
In the embodiment of FIG. 4 the structure is much simpler as the moist air vent 29 as well as the barrier air vent 30 are considerably smaller.
Having described our invention as related to the embodiments shown in the accompanying drawings, it is our intention that the invention be not limited by any of the details of description, unless otherwise specified. The embodiments of the invention in which an exclusive property or privilege is claimed are defined as follows:
We claim:
I. An appliance, comprising: a cabinet having exterior walls and an interior normally containing warm moist air; moist air vent means in one said wall having an exit opening venting warm moist air from said interior; a surface member adjacent said vent means; air passage means in said one wall having an entrance to ambient air and an exit above said entrance located between said moist air exit opening and said surface member to provide an ambient air barrier between said vented moist air and said surface member; and means for heating said air passage means to produce a rising convection air flow therethrough.
2. The appliance of claim 1 wherein said means for heating comprises a heat conducting partition between said cabinet interior and said air passage means.
3. The appliance of claim I wherein said one wall comprises an access door to said interior.
4. The appliance of claim I wherein said appliance is a dishwasher and said one wall comprises an access door to said interior.
5. The appliance of claim I wherein said surface member is above said moist air vent means, and said air passage means exit is closely adjacent said moist air exit.
