' DESCRIPTION or A PREFERR D EMBODIMENT 1 KNOCK-DOWN ELECTRIC FOOD SMOKER BACKGROUND OF TI-IE INVENTION Various types of collapsible food smoking appliances have been proposed and usedwith some degree of success; They havehad several shortcomings however, in that they-have either not been completely, collapsible having required special tools or fastening means to hold I the parts together, or have been complicated in design and expensive to manufacture, and difficult to assem- I ble and disassemble. 4
SUMMARY OF THE- INVENTION The present invention provides an electric food smoker which can be readily and quickly assembled or disassembled, particularly, the various panelsforming I the walls and their associated interior baffles. The assembled panels'can then be quickly attached to an integral base unit which includes'an electric heater, and
drawings. I, I
BRIEF DESCRIPTION OF THE DRAWINGS FIG. I is aper'spective view-of two side panels and the rear panel when laidaflat on the floor or the like prior to assembly, the interior baffles of the assembly already being inserted .in .the side panels;
FIG. 2 is a cross sectional view taken along line 2-2 in FIG. 1; I FIG. 3 is a cross sectional view taken the line 33 in FIG. 1;
FIG. 4 is a cross sectional view taken generally 'along' generally along FIG. 5 is a perspective view similar to-FIG. l, but showing one-of the end panels connected to the rear panel'after having been swung into a right angle position relative thereto} FIG; 6' is' a view similar to FIG. 5, but showing the other side panel after being intere'ngagable with the panel 5to the panel 1; I Panel 6 is fabricated similar to panel 5 and can be asrear panel and after it has been swung to a 90 degree position relative to the rear panel;
. FIG. 7 is a perspective view of the assembled smoker, the front door panel shown removed;
FIG. 8 is an enlarged, perspective, exploded view of the smoker, certain parts being shown as broken away, in section, or removed for the sake of clarity in the drawings; and I FIG, 9 is a fragmentary, enlarged, sectional view of the corner construction between the rear panel, the
I Referring particularly to FIG. 1, the rear panel 1 is generally flat-and includes a' series of outwardly extending tabs '2 which are spaced along each of the edges of the panel and, aszshown in FIG. 3, are inwardly offset slightly from the main body of the panel 1. Panel! also has holes 4 adjacent the lower end. The side panels 5 and 6 are generally similar in construction except that one-is the reverse of the other as far as. the construction of their two edges is concerned. Panel 5 will be described in detail, it being understood that panel 6 is similar in construction with the exception noted. Panel 5 along one edge has an inwardly turned. flange 8, the
flange being formed generally by fabricating that edge of the panel into a generally U-shape, thus providing a rounded corner. Along the other edge of the panel it is fabricated by again bending a'flange 10 into a generally right angle position with respect to the main body of the panel, there also being provided an enlarged rounded corner portion 11. It should be noted a series of slots 12 are formed in the flangelO, these being alignable with the tabs 2 of the back panel 1. Panel 5' has a pair of holes 13 along its lower edge.
An interior baffle plate 16 having shelf brackets 17 secured thereto as by welding is insertable into the side panel 5 as clearly shown in. FIGS. 1 and 2. The baffle plate '16 has inwardly turned flanges "l8 and 19, one
along eachofits sides for strengthening purposes and for also holding it in proper relationship within the overturned-flanges 8 and 10 of thepanel 5. It should also be noted that the baffle 16 has a series of slots 20 formed along its rear side, which slots are also alignable with the tabs 2 of the rear panel 1 and with the slots 12 of the panel 5.
With this construction, it'will be seen that when the parts are disassembled as in FIG. 1, the panel 5 is.
moved into engagement withthe panel land morepar' ticularl'yso that the tabs'2 enter the slots 12 of the I panel 5 and the slots 20 of the'baffle 16. As the panel 5 is then raised to a right angular position with respect to panel 1, the tabs 2 fully enterthe slots and thereby lock the baffle in respect to panel sern'bled in the manner, as shown in the sequence of FIGS. 1 and 5.
After therear and side panels have thus been assern- I bled together withthe interior baffle plates, the unit is raised to the vertical position where the top 30 (FIG.
8) can be slipped over the assembled panels in which holes 31in the top are aligned with holes 32 of the panels and bolt means 34 are inserted to hold the top and sides in assembled relationship. As also shown in FIG. 8, a base unit 40 containing a heating unit 42 fixed thereon is similarly rigidly connected to the side panels by bolt means 44 which extend through holes 45 in. the side-panels and into nuts 47 that have been permanently affixed to the downwardly extending flanges 49 ofthe base unit 40. The'floor 50 of the base unit 40 also has upstanding brackets 51 fixed thereto as by spot welding or the like, and these brackets'support a pan containing smoke producing material a distance above the heating unit 42. An electric conduit 55 extends from the rear end of the base unit 40 and connects the power source (not'shown) to the heating unit 42. The slots 3 in the rear panel areadapted to slip over the out- 'wardly extending conduit 55.
has an elongated open slot 3 in its lower end and also The larger holes 4 and 13 adjacent the lower edge of the panels are alignable with holes 57 in the base unit P and permit a controlled amount of air to enter under the base unit as is required in electric food smokers of this character.
5 and also lock the supported on the brackets 17 for supporting food thereon which is to be smoked.
A removable door 62 is provided and has an inwardly turned flange 63 along each of its vertical sides which frictionally engages flange 8 of sides and 16 and thus requires no additional fastening-means. Door 62 also has a small swingable door 64 having a slotted opening 65 through which the handle of the pan (not shown) can extend. The pan can thereby be removed by simply pulling it outwardly andthus opening the door 64.
1. Sheet metal panels construction for a knock-down electric food smoker cabinet comprising, two vertical side panels each having a flange extending at right angles and located along the rear edge of each panel, slots located in said flanges, an interior baffle plate located in parallelism along the inside of eachof said side panels, said baffle plates having slots which are alignable with said slots in said side panels, a vertical rear panel having tabs extending outwardly from each of its sides and which tabs are inserted in said aligned slots of said baffles and side panels to thereby rigidly hold said baffle plates, said side panels and said rear panel together in assembled relationship.
