Abstract

Abstract A water-impervious liner for use in a humidifier having a rotatable drum provided with an evaporator medium and a liquid-holding chamber through which the drum is rotated, said liner being conformed to the shape of the chamber. In one of the embodiments having a single liner, the liner is divided into two chambers by means of a dividing wall having an aperture for the flow of liquid between the chambers. According to an embodiment having a plurality of liners, there is provided a water-impervious liner assembly for use in a humidifier having at least two chambers for holding liquid, wherein the humidifier liner assembly includes a first and a second water-impervious liner and a conduit means interconnecting the two chambers, and the conduit means is attached to the first liner and to the second liner in a watertight manner.

Claims Analysis

Total Claims: 7
Claim 1
Independent Claim 218 words
The combination of a water-impervious humidifier liner assembly and a humidifier having a rotatable drum provided with an evaporator medium, a first chamber and a second chamber being provided with a common wall, said first chamber accommodating the rotatable drum so that the water is applied to the evaporator medium, said second chamber providing a reservoir for the water, and an opening in the common wall for passage of the water between said first chamber and said second chamber, wherein the humidifier liner assembly comprises: a water-impervious first liner for said first chamber, said first liner being substantially conformed to the shape of said first chamber and provided with a first aperture aligned with said opening; a water-impervious second liner for said second chamber, said second liner being substantially conformed to the shape of said second chamber and provided with a second aperture aligned with said opening; and a hollow plug, inserted within said opening and press-fitted into said first aperture and said second aperture, said hollow plug being constructed from a water-impervious material which expands upon exposure to water whereby a water-tight seal is created between said plug and said first liner and between said plug and said second liner for the flow of water through said hollow plug between said first liner and said second liner.
Claim 2
Dependent Claim 218 words
The combination of a water-impervious humidifier liner assembly and a humidifier having a rotatable drum provided with an evaporator medium, a first chamber and a second chamber being provided with a common wall, said first chamber accommodating the rotatable drum so that the water is applied to the evaporator medium, said second chamber providing a reservoir for the water, and an opening in the common wall for passage of the water between said first chamber and said second chamber, wherein the humidifier liner assembly comprises: a water-impervious first liner for said first chamber, said first liner being substantially conformed to the shape of said first chamber and provided with a first aperture aligned with said opening; a water-impervious second liner for said second chamber, said second liner being substantially conformed to the shape of said second chamber and provided with a second aperture aligned with said opening; and a hollow plug, inserted within said opening and press-fitted into said first aperture and said second aperture, said hollow plug being constructed from a water-impervious material which expands upon exposure to water whereby a water-tight seal is created between said plug and said first liner and between said plug and said second liner for the flow of water through said hollow plug between said first liner and said second liner.
Claim 3
Dependent Claim 218 words
In combination with a humidifier having a rotatable drum provided with an evaporator medium, a first chamber and a second chamber for holding water, said first chamber and said second chamber being provided with a common wall, said first chamber accommodating the rotatable drum so that the water is applied to the evaporator medium, said second chamber providing a reservoir for the water, and an opening in the common wall for passage of the water between said first chamber and said second chamber, the improvement comprising: a water-impervious first liner for said first chamber, said first liner being substantially conformed to the shape of said first chamber and provided with a first aperture aligned with said opening; a water-impervious second liner for said second chamber, said second liner being substantially conformed to the shape of said second chamber and provided with a second aperture aligned with said opening; and a hollow plug, inserted within said opening and into said first aperture and said second aperture, said hollow plug being constructed from a water-impervious material which expands upon exposure to water whereby a water-tight seal is created between said plug and said first liner and between said plug and said second liner for the flow of water through said hollow plug between said first liner and said second liner.
Claim 4
Dependent Claim 218 words
In combination with a humidifier having a rotatable drum provided with an evaporator medium, a first chamber and a second chamber for holding water, said first chamber and said second chamber being provided with a common wall, said first chamber accommodating the rotatable drum so that the water is applied to the evaporator medium, said second chamber providing a reservoir for the water, and an opening in the common wall for passage of the water between said first chamber and said second chamber, the improvement comprising: a water-impervious first liner for said first chamber, said first liner being substantially conformed to the shape of said first chamber and provided with a first aperture aligned with said opening; a water-impervious second liner for said second chamber, said second liner being substantially conformed to the shape of said second chamber and provided with a second aperture aligned with said opening; and a hollow plug, inserted within said opening and into said first aperture and said second aperture, said hollow plug being constructed from a water-impervious material which expands upon exposure to water whereby a water-tight seal is created between said plug and said first liner and between said plug and said second liner for the flow of water through said hollow plug between said first liner and said second liner.
Claim 5
Dependent Claim 186 words
In combination with a humidifier having a rotatable drum provided with an evaporator medium, a first chamber and a second chamber for holding water, said first chamber accommodating the rotatable drum so that the water is applied to the evaporator medium, said second chamber providing a reservoir for the water, and a means interconnecting the first chamber and the second chamber for passage of the water therethrough, the improvement comprising: a water-impervious first liner for said first chamber, said first liner being substantially conformed to the shape of said first chamber and provided with a first aperture aligned with said interconnecting means; a water-impervious second liner for said second chamber, said second liner being substantially conformed to the shape of said second chamber and provided with a second aperture aligned with said interconnecting means; and a hollow plug, inserted within said interconnecting means and through said first aperture and said second aperture whereby the water flows through said hollow plug between said first liner and said second liner, said hollow plug being attached to said first liner and to said second liner in a water-tight manner.
