Description

FIELD OF THE INVENTION

This invention relates to a device and system for ventilating an area and removing undesirable and unhealthy bacteria and other particles from the air and in particular this invention relates to an air ventilation device and system in which the direction of the flow of air through the device or system can be adjusted. More particularly, this invention relates to an air ventilation device and system for use with animal containers to reduce the order particles that accumulate in the vicinity of the animal container as the result of an animal residing in the container.

BACKGROUND OF THE INVENTION

An air purifier is a device which aims to free air from contaminants. The popularity of air purifiers spur from the results from environment researches which claim that the air inside homes are dirtier than the air outside of homes. Air purifiers are particularly beneficial for allergy sufferers and asthmatics or those who wish to reduce second-hand smoke. Allergy-inducing culprits are known as allegens. Allergens can come in the form of dust or pollen as well as pet dander and mold spores. Hazardous smoke particles and airborne gases may also find their way into homes and bedrooms. Because of the significant amount of time most people spend indoors, many wish to ensure air purity.

Various techniques are used in air purifiers in the current market to accomplish indoor air purification. These techniques include mechanical filters, absorbents such as charcoal, and electrostatic charges or ionizers. The most popular sort of filters for air purifiers is the HEPA filter. The Department of Energy has rigid requirements manufacturers must pass to meet HEPA requirements. Additional setups include germicidal UV light and the emission of ions into the air to react with contaminants and making them harmless enough to breathe. Although air purifiers strive to make the air as clean as possible, no commercial air purifier is capable of producing a room as clean as needed in situations requiring an especially clean environment, such as hospital surgical rooms or sensitive manufacturing like optics or computer processors.

In addition to the general contaminants that are in the air, owners of pets also live with the contaminants that come from the animals. Millions of households keep domesticated pets indoors. Allowing the animal to remain indoors reduces exposure to infectious diseases, territorial disputes with other neighborhood animals, and exposure to the harsher elements of weather, such as rain, snow, the cold of winter and the heat of summer. Although many pet owners keep their pets indoors, a shortcoming of current pet enclosures is that they absorb and emit pet odors that can foul the smell of the entire house or apartment surroundings. For example, the inclusion of many materials such as wood and/or other natural materials, and/or natural or synthetic fabric into an enclosure can trap urine and other sources of unpleasant odors associated with animals. Attempts to reduce the absorption of odors have generally focused on fabricating the structure entirely of metal or other non-porous materials. These odors contribute to the contamination that is generally in the air as previously described.

One attempt to reduce pet odor is described in U.S. Pat. No. 6,997,138. This patent describes a pet enclosure having a moisture and odor-resistant, plastic, rattan-like material woven onto a frame. Although this odor-resistant plastic does reduce some of the odor coming from the animals, a substantial amount of pet odor remains in the air.

There remains a need for an improved and flexible air ventilation system that can be adapted to remove contaminants and animal odors from the air.

This furniture piece can also contain a floor. The front side 22 has an opening 32, which covers a large portion of the front side. This large opening allows for animals to easily enter the furniture piece. The opening also allows for easy insertion of toys and food and water trays into the furniture piece. In addition, small vent openings 34 and 36 can be included the side walls. These opening improve ventilation in the furniture piece. The front side also has a lip 38 that extends up from the base.

FIG. 5 shows a side view of a configuration of an air-cleaning device of the present invention. In this configuration, the air cleaner housing is a stair-step device. In this configuration, one air vent 50 is positioned in the back wall 52 of the housing. A side vent 54 is positioned in the side wall 56 of the housing. A second side vent, not shown, is also positioned in the side wall opposite side wall 56. These two side vents are symmetrical. Air flows through the air vent 50 and into the air-cleaning device. The air then flows through the cleaning element 58. The air cleaning element can be one such as those manufactured by Natural Air (model number Natural Air 50) the cleaned air then flows from the cleaning element and out of the air-cleaner through vents 54 in the side wall. This housing is suited to be positioned adjacent an animal container such as the one described in FIG. 4.

FIG. 6 shows a side view of an alternate stair-step configuration of an air-cleaning device. In this configuration, vent 50 is still in the back wall 52. However, the second vent 60 is at the front 64 of the stair-step housing. In this embodiment, the air flows from the cleaning element 58 and out of the air cleaning device through vent 60.

FIG. 7 shows the air flow pattern of the configuration illustrated in FIG. 5. As previously described, flows through vent 50 and the cleaning element 58. Air then flows out the cleaning device through vents 46 in the side walls. This configuration can also have a wall 62 to helps facilitate the flow of air through the side vents.

FIG. 8 shows the flow air through the configuration illustrated in FIG. 6. Air is drawn into the cleaning device through vent 50. The air then travels through the air cleaning element 58 and out of the air cleaning device through vent 60.

FIG. 9 a shows an alternate embodiment of the air ventilating system of the present invention. This embodiment is another stair-step design. Shown are two steps 90 and 91 with a front side 92 and a back side 93. An opening 95 in the upper section of the back side provides an inlet through which air will flow into the device. The cleaning element 94 is attached to the back side 92 and is positioned such that it can draw air through the opening 95 into the housing. Openings 96 are on each side of the housing. FIG. 9b shows a cross-section view of the back side of the housing. Shown are the opening 95 and side openings 96.

FIG. 10 a shows a plug element. This plug element 98 can be positioned on the inside of the back wall 92 and positioned such that the wall opening 95 is aligned with opening 95a in the plug element. An electrical plug 97 provides a means to supply power to the air cleaning element 94. FIG. 10b shows a side cross-section view of the plug element attached to the air cleaning element. A gasket material 99 can be positioned between the plug element 98 and the air cleaning element 94 to form a seal between the air cleaning element and the plug element.

FIGS. 11 a, 11 b and 11c show different configurations of the air cleaning device. In these configurations 11b and 11c, a wall 100 is constructed to enable the flow of air between side openings as previously shown in FIG. 8. The wall 100 contains the plug element 98. The air cleaning element can be positioned on either side of the wall depending on which direction is flow is desired. In FIGS. 11b and 11c, the air will flow into the air cleaning unit through one opening, through the air cleaning element and out through the other side opening.

FIG. 12 shows a side view of the air cleaning element on a track in the housing to facilitate linear and circular movement of the air cleaning element in the housing. This configuration provides for movement of the air cleaning element to direct air flow through the housing as desired.

FIGS. 13 a and 13b show different configurations of the track 102. A complete floor 104 can be positioned in the housing to support the track. In the alternative, FIG. 13b shows a partial floor 106 to support the track 102. FIGS. 14 and 15 show the air cleaning element attached to the housing. The pin 110 that engages the track allows for linear and circular movement of the air cleaning element within the housing.

In another application, it may be desirable or necessary for the cleaning device to be positioned such that air flows in through the side of the device instead of the back as previously described. For this application, it may be necessary to change the orientation of the cleaning element such that it faces the side vent. The orientation of the cleaning element could be changed using a dial on the external surface of the housing. This dial would be connected to a control mechanism that is connected to the cleaning element. For example, to rotate the cleaning element in a clockwise direction, the user could turn the dial in a clockwise direction until the desired orientation of the cleaning element is obtained. For maximum efficiency, it is better to have the best alignment of the cleaning element with the vent through which air will be drawn into the cleaning device.

The various orientations of the cleaning element can be in a circular direction or they can be combination of circular and linear directions. To facilitate this combination of linear and circular orientations, the cleaning element could have pins on the top and bottom. The top pin could be in mechanical communication with an external control dial. The bottom pin could be positioned in a linear track. The attachment of the pin with the track could be in a manner such the user could move the cleaning element in a linear direction and could also rotate the cleaning element while moving it in a vertical direction.

FIGS. 16, 17 and 18 show various configurations of the air cleaning element on the track. FIG. 16 shows a configuration in which the air cleaning is drawing air into the housing in the back side of the housing as illustrated in FIG. 9a. In FIG. 17, the air cleaning element can be moved linearly and rotated circularly such that is draws air into through a side opening and out of the housing through the opposite side opening. FIG. 18 is an orientation of the air cleaning element such that it draws air into the housing through the side opening that is opposite the side opening shown in FIG. 17. In each mentioned embodiment, the air travels through the air cleaning element before existing the housing.

FIG. 19 shows an embodiment of the system of the present invention. This system comprises an air cleaning device in combination with an animal containing device. This animal containing device is similar to the one shown in FIG. 4. The animal container 70 is positioned adjacent the air-cleaning device 72. The air-cleaning device is positioned such that it covers the vent in one side of the animal container. The positioning of the air-cleaning device should be such that the vent 36 of the animal container is aligned with the vent 50 of the air cleaning device. As shown, this configuration of the air-cleaning device has the vents in the side walls. The air inside the animal container space is contaminated with the smell of the animal. As mentioned, this smell filters into the entire room. With the present invention, the air 80 from the containing is drawn out of the container 70 through the side vent 36 and back vent 50 and into the air cleaning device 72. When in the air cleaner, the cleaning element cleans the air. The air 80 then flows out of the cleaning device through the side vents.

The system of the present invention can also comprise a configuration in which the structures as shown in FIG. 19 are combined as one structure having multiple sections.

The structures described in this invention can be constructed from any conventional building material such as metal, wood or plastic.
