United States Patent ELECTRICAL DEODORIZING DEVICE David W. Yalfe, Philadelphia, Pa., assignor, by mesne assignments, to Cory Corporation, Chicago, Ill., a corporation of Delaware Application October 13, 1958, Serial No. 767,004
Claims. (Cl. 219-19) This invention relates to a room deodorizing device, and it particularly relates to a deodorizer which can be electrically energized or deenergized.
Although there are various room deodorizers on the market today, they .are generally in the form of sprays contained in squeeze bottles or aerosol bombs. These sprays create mists or fogs consisting of tiny fluid particles which clog the atmosphere of the room and often form undesirable deposits on walls, fixtures or furniture. Furthermore, the containers must be stored when not in use and may be lost or misplaced between uses.
It is one object of the present invention to overcome the above and other disadvantages of prior deodorizers by providing an electrically energized deodorizing device which can be permanently installed on any wall or other flat surface and which can be utilized immediately whenever needed and thereafter be immediately deactivated.
Another object of the present invention is to provide a deodorizing device which utilizes easily replaceable deodorant parts which can be replenished when worn out.
. Another object of the present invention is to provide a deodorizing device of sturdy construction and pleasing appearance which is relatively inexpensive to produce.
Other objects and many of the attendant advantages of this invention will be readily appreciated as the same becomes better understood by reference to the following detailed description when considered in connection with the accompanying drawings, wherein:
Fig. 1 is a perspective view of a device embodying the present invention.
Fig. 2 is a sectional view taken on line 22 of Fig. 1.
Fig. 3 is a sectional view taken on line 33 of Fig. 1.
Fig. 4 is a sectional view taken on line 44 of Fig. 1.
Fig. 5 is an exploded view of the device of Fig. 1.
Referring now in greater detail to the various figures of the drawings wherein similar reference characters refer to similar parts, there is shown a deodorizer device, generally designated 10, comprising a casing 12 which consists of a rear casing section 14 and a front casing section 16. These casing sections may be constructed of any desired material but are preferably constructed of a plastic such as polystyrene.
The rear casing section 14 comprises a rear wall 18 integral with a pair of side walls 20 and 22. All three of these walls 18, 20 and 22 are provided with internallyextending top flanges as at 24, 26 and 28 which are integral with each other. The flange 24 of the rear wall is somewhat wider than the other two flanges (as clearly shown in Figs. 1 and 5).
The rear wall 18 is provided with an indented or internally recessed portion 30 at the external center of which is provided a lug 32 (see Fig. 3). This lug 32 is provided with a key-hole shaped opening 34 which extends through the lug and through the wall 18. The opening 34 is adapted to receive the head of a nail, screw or the like having its other end inserted in the room wall or other supporting surface. In this manner, the device may be easily hung upon and removed p from the supporting surface by merely sliding the device up or down to permit entry ofthe. nail head into and out of the enlarged portion of the hole 34. The side wall is provided with a slot 36 to receive a switch button tobe hereinaftermore fully described. Mounted on the inner surface of rear wall 18 is a bracket 38 comprising a rear plate 40 a downwardlydepending extension 42 on one side and a downwardlydepending extension 44 on the other side. The bracket 38 is connected to the inside surface of wall 18 by rivets or the like 46 passing through holes 48 in the extensions 42 and 4'4 and through apertured bosses 50 in the wall 18. Spring detents 51 are struck out of the extensions 42 and 44 and frictionally engage. under the shoulder formed by the lower edge of recessed portion 30.
I A spring finger 52, having an upwardly extending flange 54 at its free end, is struck out from the bottom of plate plate 40 and extends forwardly therefrom.
Seated on the spring finger 52, in spaced relation to flange 54, is a ceramic block 56 having a rectangular recess 58 therein. Thebottom of the recess is defined by;.a framing portion of the block having an arcuategroove 60 at each end. At each side of the recess, the block-is provided with holes: 62.
Adaptedto seat within the recess 58 of block 56 is a rectangular resistor element 64, and on top. of the block 56 is adapted to rest a second ceramic block 66. This second block 66 is shaped similarly to block 56 but is provided with a centrally arranged, rectangular aperture- 68 which encompasses the resistor 64 when the two blocks are assembled and held together by means of pins, rivets or the like, shown at 70, which extend through;
holes 72 in the block 66 and holes 62 in block 56..
The framing" portion defining the lower edge of the aperture 68 in block 66 is provided with a groove 74 at each end. These grooves 74 mate with grooves 60 inv block 56 to form passages through which extend the' wires 76 and 78 respectively connecting the resistor element 64 with a slide switch 80 mounted on a side flange section 82 of extension 42 and with an electrical plug element 84. The wire 78, in leading to plug 84, first passes through an insulating sleeve 86 positioned in an aperture in a forwardly-extending flange 88 extending from the lower edge of extension 44. The sleeve 86 is provided with a guide 89 at its upper end. The circuit is completed by a wire 90 connecting the plug 84 with the switch 80 after first passing through sleeve 86.
The switch 80 is provided with an actuating button 92 which projects through a slot 94 in the flange 82 and through the slot 36 in the side wall 20 of easing section 14 into a position where it is readily accessible to the user. At its inner side, the switch 88 is provided with an insulating cover 96 having apertures through which electrical wires extend.
The front section 16 comprises an inwardly-bowed front wall 98 provided with a top inwardly-extending flange 100 and side flanges 102. The flanges 102 are integral with lower side flanges 104, each being provided with an inwardly-extending lip 106. Ribs 108 extend along the underside of the lower wall 110 adjacent the flanges 104. These ribs 108 act as feet for the device if it is to be stood up in place instead of hung and also as strengthening means.
The front wall 98 is provided with louvered openings 112 at its lower portion, these openings extending into the bottom wall 110.
The rear edge 114 of wall 110 is slightly recessed and is provided with a slot 116 which mates with a vertical slot 118 in wall 18 of section 14 to provide an opening through which wires 76 and 78 extend.
The sections 14 and 16 are assembled by sliding the rectangular ribs 120 on the bottom of section 14 into thechannels IZZIormedon-the interior of flanges 104, and frictionally-retaining the two sections in place.
When the casing 12 is assembled, with its two sections 14 and 16 held together, a slot 124 is formed at the top. This slot' 1 24 coincides with the space between the block 66 and fiange 54 of finger52 so that a porous ceramic block 126 impregnated with adeodorizing fluid can be slipped through the slot 124 into position between the resistance element 64and the retaining flange 54 which resiliently holds the block 126 in place. A handle 128 is provided on block 126 for easier handling.
With the block 126 in place, the switch 80 can be operated to heat up the resistor 64. This heat vaporizes the deodorant fluid in block 126. Meanwhile, air flows through louvered openings 112 and up past the deodorant block and out slot 124. As it passes through the device, this air-entrains the deodorant vapor and disperses it through the room by convection.
- When it is desired to deactivate the device, it is merely necessary to push button 92 to open switch 80.
Whenever one block 126 becomes worn out; that is when an insuflicient amount of impregnant remains, it can be instantly and easily replaced with a fresh block. These blocks 126 can be sold separately as refills.
Obviously many modifications and variations of the present invention are possible in the light of the above teachings. It is, therefore, to-be understood that within the scope of the appended claims, the invention may be practiced otherwise than as specifically described.
