Definitions
- the installer of the humidifier is given the opportunity of mounting the humidifier either to the underside of the duct or to the vertical side of the duct, as well as to make an over flow drain connection through one of several, alternate drain holes.
- This invention relates to an easily assembled and disassembled drain connection comprising a resilient grommet located in and sealed to the edge of one of the holes of the Walls of the sump, and a tubular member extending through and in sealed relationship with the grommet.
- a further improvement is forming the inlet edge of the tubular member at an upwardly inclined angle so that the flow will be concentrated at the lowest point of the inlet edge and the velocity of the flow will be at a maximum.
- a humidifier in the hot air distribution duct or furance plenum of the heating system.
- the main elements of a furnace humidifier are a power driven air handling device, and evaporating elements means for wetting the element so that the hot air is caused to pass through the element and pick up a percentage of the moisture from the element before the hot air proceeds through the distribution duct.
- a humidifier is customarily wired from a source of electrical power in a manner to operate only when the arm air furnace blower is running.
- a humidistat is furnished with the humidifier and it controls an electrically operated water valve that supplies water to the humidifier. This water is fed to a water distributor for an evaporating element.
- This element is a wettable filter pad having high surface area through which the hot furnace air can Patented Dec. 30, 1969 "ice be drawn.
- An electric fan or blower provides the air moving function through the evaporating element.
- a slight amount of excess water is allowed to drain from the ele ment and accumulate in a sump and to be removed through the drain connection of the present invention.
- This continuous draining or flushing action tends to keep mineral concentrations down by allowing them to be washed away by the flow instead of collecting on the internal parts of the humidifier.
- the present invention is accordance with one form thereof, relates to the sump of a humidifier or broadly a liquid container having a bottom wall and raised side walls. There are alternate drain holes formed in the walls of the sump as well as means for closing the drain holes.
- a drain connection is formed through one of the holes and it includes a resilient grommet fastened in the hole and a tubular member extending through the grommet and sealed with respect to the grommet while the grommet is sealed with respect to the edge of the hole.
- a further improvement is to form the upper end of the tubular member with a funnel shape which has an inlet edge formed at an inclined angle whereby the drain flow will be concentrated at the lowest point of the inlet edge and the velocity of the water flow will be at a maximum.
- FIGURE 1 is a perspective view of a liquid container such as the sump of a furnace humidifier showing alternate drain holes in the bottom wall and the side wall of the sump.
- FIGURE 2 is an elevational view of a humidifier housing containing the alternate drain hole arrangement of FIGURE 1.
- FIGURE 3 is a fragmentary detailed view taken on the line 33 of FIGURE 2 and showing the means for closing the drain holes until one of them is chosen, by using knock-outs which are formed by scoring the housing wall.
- FIGURE 4 is a fragmentary, cross-sectional, elevational view on an enlarged scale taken through the center of one of the drain holes in the bottom wall of the container having a drain connection of the present invention mounted therein.
- FIGURE 5 is a view similar to FIGURE 4 of a second modification of the present invention showing the upper end of the tubular member of the drain connection with an inlet edge formed at an upwardly inclined angle so that the flow is concentrated at the lowest portion of the inlet edge.
- FIGURE 1 there is shown a box-like container of metal or plastic material for forming a drain pan or sump of a furnace humidifier and it has a bottom wall 11 and raised side walls 12.
- a plurality of alternate drain holes 13, 14 and 15 are formed in the walls of the container for ease in making a drain connection with the container depending on how the humidifier is mounted to a hot air distribution duct.
- the drain can extend from the bottom wall 11, but in others the humidifier must be turned on its side and the drain extend through side hole 15.
- These drain holes 13, 14 and 15 are normally closed by a knock-out 17 as is best seen in FIGURE 3.
- Each knockout is formed by scoring the wall of the container in a circular pattern as at 19. This scoring substantially outlines the configuration of the knock-out, and a slight blow with a hammer or chisel will cause the knock-out to become disengaged from the wall and thereby create the proper drain hole.
- the drain connection comprises a resilient grommet 23 that is adapted to be fastened in the drain hole 13, as well as a tubular member 25 that is adapted to extend through the grommet.
- the grommet is made of a rubber material such as neoprene or the like, and it is formed with a central opening 27 and a peripheral groove 29 which is adapted to receive the peripheral edge of the drain hole 13.
- the relative size of the groove 29 and the resiliency of the grommet is such that the groove embraces the peripheral edge of the hole 13 and provides a water tight seal.
- the central opening 27 in the grommet is of a diameter slightly smaller than the diameter of the tubular member 25 so that there is a force fit between the tubular member and the opening which likewise creates a sealing action therebetween.
- the upper end of the tubular member 25 is formed in a conical or funnel shape 31 which is seated against the top of the grommet.
- FIGURE 4 shows a push nut 33 of spring material forced over the lower end of tubular member 25 and into engagement with the underside of the grommet to cooperate with the enlarged upper end 31 of the tubular member and exert a compressive force against the grommet to provide a liquid sealing action as well as to prevent relative displacement of the parts during the use of the humidifier when vibrations might be set up by the furnace blower or humidifier fan and tend to cause the tubular member to become dislocated in the grommet.
- a drain hose 35 of flexible material is installed over the lower end of the tubular member 25 for carrying off the drain flow.
- distilled water would be ideal, or any water containing no mineral deposits
- tap water is naturally used in a furnace humidifier because of its convenience and economy.
- the water being circulated over the evaporating element may remove additional foreign matter from the air so that during the heating season several pounds of scale-forming material may collect in the humidifier system.
- drain connection of the present invention is a low water flow device calcium deposits accumulate on the evaporating element as well as on the walls forming the sump and they tend to clog the passageways especially in the vicinity of the drain connection.
- the volume of the flow so as to provide a proper flushing action and reduce the rate of sediment, scale and slime buildup within the humidifier system.
- a drain connection formed in said bottom wall and raised side walls, a drain connection formed in said bottom wall and comprising a hole formed in the bottom wall, a resilient grommet fastened in said hole, the grommet having a central opening as well as a pheripheral groove for receiving the peripheral edge of the hole, and a tubular member of slightly larger size than the grommet opening extending through said opening, the upper end of the tubular member being of funnel shape and in engagement with the grommet, said funnel shaped upper end of the tubular member having an inlet edge formed at a raised inclined plane of between about 10 and about 40 whereby the inlet flow will be at the lowest point of the inlet edge and the velocity of the liquid flow into the tubular member will be at a maximum.
- a humidifier sump having a bottom wall and raised side walls for containing water therein, alternate drain holes formed in the bottom wall and in the side walls, means for closing the drain holes, a drain connection formed through one of the holes and comprising a resilient grommet fastened in a hole through the bottom wall, the grommet having a central opening therethrough and peripheral means for sealing the grommet to the peripheral edge of the hole, a tubular member extending through the grommet opening, the upper end of the tubular member being enlarged and seated on said grommet, and a push nut forced over the lower end of the tubular member and against the grommet to exert in cooperation with the enlarged upper end of the tubular member a compressive force on the grommet.
- a humidifier sump as recited in claim 3 wherein the peripheral means for sealing the grommet comprises a continuous groove extending around the grommet for receiving the peripheral edge of the hole.
