Claim 15

A humidifier according to claim 1 wherein said cavity communicates with said reservoir.

Claim 16

A humidifier comprising: base means defining a reservoir adapted to retain water to be dispersed and recess means adapted to receive leakage; humidifier means for inducing dispersal of water retained by said reservoir; tank means comprising a vessel having an open end and a lid sealed in said open end and forming a bottom wall for said vessel, said tank means being supported by said base means, and said lid defining a discharge opening communicating with said reservoir; and partition means surrounding said sealed lid and extending below said tank means into said recess means, said partition means forming an enclosure projecting downwardly from said lid.

Claim 17

A humidifier comprising: base means defining a reservoir adapted to retain water to be dispersed and recess means adapted to receive leakage; humidifier means for inducing dispersal of water retained by said reservoir; tank means comprising a vessel having an open end and a lid sealed in said open end and forming a bottom wall for said vessel, said tank means being supported by said base means, and said lid defining a discharge opening communicating with said reservoir; and partition means surrounding said sealed lid and extending below said tank means into said recess means, said partition means forming an enclosure projecting downwardly from said lid.

Claim 18

A humidifier according to claim 15 wherein said partition means is integrally formed with said tank means.

Claim 19

A humidifier according to claim 15 including skirt means surrounding said discharge opening and projecting downwardly into said reservoir, said skirt means adapted to establish a given water level therein.

Claim 20

A humidifier according to claim 17 including a valve means disposed in said discharge opening and adapted to produce said given water level in response to the differential pressure across said valve.

Claim 21

A humidifier according to claim 18 wherein said enclosure projects to substantially the bottom of said recess means.

Claim 22

A humidifier according to claim 19 wherein said recess means is annular and conforms substantially to said enclosure.

Claim 23

A humidifier according to claim 20 wherein said lid further defines an inlet opening, said base means further defines cavity means, and including wall means surrounding said inlet opening and extending below said tank means into said cavity means.

Claim 24

A humidifier according to claim 21 including a removable cap closing said inlet opening.

Claim 25

A humidifier according to claim 22 wherein said wall means form a tube projecting outwardly from said inlet opening into said cavity.

Claim 26

A humidifier according to claim 23 wherein said tube projects to substantially the bottom of said cavity.

Claim 27

A humidifier according to claim 24 wherein said tube comprises an outer end portion projecting into said cavity to a level below said given water level, and said enclosure projects into said recess means to a level below said given water level.

Claim 28

A humidifier comprising: base means defining a reservoir adapted to retain water to be dispersed and having an annular upwardly projecting annular skirt having an upper edge and defining an enclosure communicating with said reservoir; humidifier means for inducing dispersal of water retained by said reservoir; and tank means comprising a vessel having an open end and a lid permanently sealed in said open end along a joint at the outer periphery of said vessel and forming a bottom wall for said vessel, said tank means being supported by said base means with said joint disposed below said upper edge such that leakage through said joint is retained by said skirt within said enclosure for deposit into said reservoir.

Claim 29

A humidifier comprising: base means defining a reservoir adapted to retain water to be dispersed and having an annular upwardly projecting annular skirt having an upper edge and defining an enclosure communicating with said reservoir; humidifier means for inducing dispersal of water retained by said reservoir; and tank means comprising a vessel having an open end and a lid permanently sealed in said open end along a joint at the outer periphery of said vessel and forming a bottom wall for said vessel, said tank means being supported by said base means with said joint disposed below said upper edge such that leakage through said joint is retained by said skirt within said enclosure for deposit into said reservoir.
