A portable humidifier typically has a case enclosing a pan-like water container, and humidifying mechanism is supported within the case effective to dissipate container water as vapor to the surrounding environment. The trend is toward decorative cases simulating quality pieces of furniture, and such cases are typically fabricated of metal or plastic, frequently also having certain of the panels grained and/or vinyl covered to give a decorative wooden appearance. The fabrication of certain decorative plastic cases frequently is by a molding specialist, who then ships the cases to the humidifier manufacturer who then in turn installs the working humidifier components in place, Since most such box-like cases cannot properly be nested together or stacked to form compact packages, this practice is expensive, Moreover, the working humidifier components, when operatively united to the case as intended, are most commonly quite inaccessible for testing, recalibration and/or repair or replacement.
One main object of this invention is to provide a case construction comprised of fabricated generally flat panels which can be snapped and/or bolted together and interlocked quite easily to form the case, thereby economically allowing the separated fabrication of the panels and assembly thereof to form the case.
Another main object of this invention is to provide, in the design ofa portable humidifier, for the total support of substantially all working humidifier components from only a single case panel, and the ready assembly of this panel to the remainder of the case, thereby allowing the assembly and exposed testing as a unit of all components even before the final assembly of the humidifier.
The many advantages of this invention will be more fully understood and appreciated after reference to the accompanying drawings, wherein:
FIG. 1 is a perspective view, broken away for greater clarity, of a humidifier construction utilizing this invention;
FIG. 2 is an enlarged sectional view as seen generally from line 2-2 in FIG, 1;
FIG. 3 is a sectional view as seen generally from line 33 in FIG. 2;
FIG. 4 is an enlarged exploded perspective view showing adjacent panels and typical cooperating locks for holding same together;
FIG. 5 is a perspective view, partly broken away for greater clarity, of the rear case wall;
FIG. 6 is an elevational sectional view as seen from lines 6-6 in FIG. I; and
FIG. 7 is a sectional view as seen generally from line 7-7 in FIG. 6.
Referring to the drawings, the disclosed humidifier I has a container 12 for water, a case 16 encloses the container l2, and a drum )8 is rotatably supported within the case partly in and partly out of the container water. The drum has one closed end 20, an annular open end 22, and thin spaced bars 23 connecting the ends and providing support for a covering mat 24 of porous material. The drum support includes a motorpowered roller 26 which engages the inner edge of the drum end 22 to rotate the drum, so that the mat 24 is wetted as it passes through the container water and is exposed to the air above the container. A motor 28 supports and rotates a fan 30 in a rear case wall opening 32 operable to draw in outside ambient air and force it through the wetted mat 24 for discharge from the case vent 34 to the surrounding atmosphere.
The case 16 is generally rectangular in shape and is comprised on a front wall 40, a pair of side walls 42, and a rear wall 44. An upper lip 46 from the rear wall 44 forms part of the top case wall, and an open grill 48 is removably supported on ledges 50 from the front. side and rear walls and defines the air outlet vent 34 and completes the top case wall. The case 16 has no bottom wall, and thus can be vertically positioned over the container to virtually hide same. Case wall ledges 52 project beyond and rest on the container to support the case at or slightly above the supporting surface. My above mentioned co-pending application discloses and claims this particular combination.
The front panel 40 has at each end rearwardly projecting parallel flanges or tongues 56 and S8, and each tongue 58 has an opening 60 therein. Each side panel 42 correspondingly has a forwardly open channel or groove 62 defined between the main panel portion and an inwardly spaced track portion 63. When the adjacent side and front panels are fitted together properly with the corners butted, the tongues 56 and 58 fit within the receiving grooves 62, and moreover a detent 64 located on the side wall snaps into the tongue opening 60 to hold the adjacent panels together. Webs 66 connect the track elements 63 to the main panel portion for stiffening the construction and further for locating the tongues and restraining shifting of the connected panels. The adjacent tongues 56 and 58 are parallel and can be coplaner for ease of fabrication separated only by a cutout 68 that receives the strenghtening web 66.
The adjacent side and front panels overlap at butted edge portions 70 which are preferably sloped relative to the main panel sections to meet tightly and hide the juncture line between them, when the panels are secured together. By sloping them to meet flush when the panels are angled at just less than the normal interior corner angle after the detents are snapped in place, the edge portions are pinched even tighter together after the panels are spread apart to the proper interior angle which more effectively hides the exposed juncture line. Each detent preferably further has a sloping lead face 74 to cam the lead end of the cooperating tongue inwardly until when the adjacent panels are butted tightly together and the detent falls into the tongue opening 60; and the build up flat 7] on the detent or the panel wall itselfis then engaged by the tongue to limit angling of the connected panels.
The tongue and groove cooperation hold the panels relative to one another to simulate almost a one-piece structure, but the panel fabrication and set up need not be at the same site to give more manufacturing flexibility to this type case construction.
The front panel 40 and/or the side panels 42 can have decorative raises 78 or recesses 79 which gives the appearance ofa structured wood cabinet, and the panels can he embossed and colored to correspond to wood grain. as is known in the molding art. When the adja cent panels are secured together. the decorative raised portions 78 blend together at the corners to give the desired overall pleasing case appearance.
The rear wall 44 is formed preferably as a one-piece plastic molding having forwardly directed side flanges or tongues 80 and spaced openings for connecting bolts 83. The tongues 80 fit within corresponding rearwardly open channels or grooves 84 formed on the adjacent side wall by the main portion of the wall and inwardly spaced flanges, and enlarged boss areas 85 on each side wall form seats for the securing bolts 83. Consequently, the rear panel can be removably secured to the U shaped snapped together side and front wall assembly, but preferably only upon some slight outward angling of the side walls relative to the front wall to close the corner juncture as noted above.
The rear wall 44 also has integrally molded therewith a number of cowls or guides for diverting air through the wetted mat 24 and supporting the operating humidifier components. Thus cylindrical cowl 90 defines the air inlet opening 32, and an integral protective grill 92 of spaced radial and circumferential ribs at the outer end of the cowl supports the fan motor 28 and also protects against accidental touching of the fan blade 30. The positioned drum matches up with and lies closely adjacent a semi-cylindrical cowl 94, and ledge 96 between the terminal ends of the drum cowl 94 projects slightly into the drum; and these serve to direct air flow through the mat 24 and to minimize leakage merely past the drum and case. A forwardly formed cylindrical boss area 99 forms a mounting support for a shaft upon which a drum supporting idle roller 100 is journaled; and the drum supporting powered drum roller 26 is keyed to the output shaft of a motor powered speed reduction unit 102 in turn secured to the rear panel wall 112. The drum is vertically supported by its open end 22 riding in the rollers 26 and 100, and is horizontally restrained by anti-friction clips 106 snapped onto the baffle ledge 96 adjacent the drum cowl 94. This provides for the drum support solely from structure associated with the rear panel, and the lower drum portion merely extends into the water container but does not receive any support therefrom.
The rear panel 44 also defines a rearwardly open cavity 114, formed by inward directed walls 110 and rearwardly offset wall 112, which cavity is suitable for receiving the electrical controls. Thus, a metal control box 118 is supported in the cavity on ledge 119, and combination on-off and humidistat control switch 120 and fan speed control switch 122 are located in this control box in appropriate electrical connection with the fan motor 28 and drum drive motor 102. A plate 126 is secured to the rear panel and to the control box to enclose the controls and hold the box within the cavity. A water level control 128 is provided on the rear panel and includes a float arm 130 pivoted at pin I32 to the panel and a link 134 connected betweeen the arm and an indicator drum 138 pivoted to the upper lip and visible through an opening thereinv A water level safety control can be provided with a linkage connection 138 between the humidistat and the indicator drum, where operation of the humidifier components is terminated when an inadequate supply of water is in the container 12.
[t is thus noted that the disclosed humidifier has a readily fabricated case comprised of a snapped together front and side panel generally U-shaped subassembly. and a bolted on removable rear panel. Also the disclosed humidifier has a design where the rear wall supports all of the working humidifier components, including all controls therefor.
This particular humidifier construction has great util ity, for example, in regard to the manner and ease of assembly. The front wall and the two adjacent side walls can be fabricated by a plastic specialist and shipped flat with like relatively well nested parts to a humidifier manufacturer and thereat can be snapped and interlocked together to the generally U-shaped subassembly. The rear wall can be supported in an appropriate fixture (not shown) and to it each of the working components, both electrical and mechanical, can be installed in place. The working components as then supported exposed on the fixtured rear panel can be operated as an actual humidifier unit. Any necessary adjustments can be made or any malfunction can likewise be easily corrected at this time since all parts are exposed and accessible. Thereafter, the rear wall with the secured working humidifier components (except for the drum which should be removed) and the U- shaped front and side wall subassembly can be connected together to define the finished humidifier case. The drum can then be located in place, and the case positioned over the water container to complete the assembly.
