A lifting device for a portable air purifying unit that includes a rectangular main support member for supporting all the component parts of the unit so that they are balanced about the support. A housing comprising a top cover and front and rear covers is attached to the support for enclosing the unit. The top cover is coextensive with the top wall of the support and contains a raised partition that extends laterally across the cover. A hand-hold passes through the center of the partition that opens into an enclosure mounted on the cover in front of the partition. The hand-hold and the chamber combine to form a handle. The front cover of the housing passes over the handle to partially shield the handle thereunder.

Lifting handle for air purifier

An air handling unit that includes a main support member and front, rear and top covers mounted on said support that forms a housing for enclosing said unit. The covers have side walls that close over the support frame in abutting contact to form an interlocking seam therebetween at closure. Ribs are mounted upon the side walls of the support frame which bias the side walls of the covers outwardly to render the seam relatively air tight at closure. Two covers are securely affixed to the main support member while the other is removably attached to the main support member by a latching means. A HEPA filter is mounted in the main support member along with a blower system for drawing air through said housing.

Air purifier unit

Apparatus for closing the front of an air purifying unit that includes a main support frame upon which is secured a rear cover and a top cover. A removable front cover is arranged to pass over the front section of the support frame and closes against the top and rear cover. A latching device acts between the support frame and the top cover to secure the cover to the frame. Biasing members are mounted upon the support frame for urging the walls of the front and rear covers outwardly and guiding the covers into edge to edge alignment.

Front access cover for air purifier

Apparatus for aligning and mounting a circuit board in a confined space that includes a pair of mounting pads extending outwardly from a wall. A tab is mounted on the wall over the pads so that a circuit board can be received between the pads and the tab. A rest mounted apart from the wall for supporting the board in a desired plane and a fastener for securing the board to the rest.

Mount for circuit board

Apparatus for retaining electrical cords of varying thickness within an open top channel. Retaining members are mounted alternately on each of the side walls of the channel each having steps that include a top step adjacent the bottom wall of the channel and a bottom step adjacent the open top of the channel. A service cord having a first thickness can be friction fitted between the top step of each member and the opposite side wall of the channel. Similarly a service cord having a greater thickness can be friction fitted between the bottom step of each member and the opposite side wall of the channel.

Retainer for power cord

A filter assembly for use in an air purifier unit having a rectangular shaped air inlet entrance to the unit blower. A rectangular shaped frame containing a HEPA filter pack is slidably received within the blower inlet. An L-shaped flange surrounds the filter frame and closes against the air inlet of the blower to provide an air seal. The top wall of the flange is offset some distance from an adjacent wall of the frame to provide a handle for the filter assembly.

A bulb mounting for air handling equipment indicator bulbs that include at least a lamp base having a top flange. The mounting includes an air handling equipment support member having a hole, and retaining surface disposed a predetermined distance above an equipment support wall, that slidably receives the lamp base so that the flange rests on the retaining surface. The mounting further includes a top cover having an opening large enough to receive the bulb, and a tube shape that presses the flange against the retaining surface. The cover top side is disposed a predetermined distance above the flange, so that the bulb is positioned and secured a precise distance relative to the top of the cover and the equipment support wall. The equipment support member is sized so that the lamp base may also have a compressible peripheral surface that is slidably received by the equipment support member, and yet presses against the support member, further positioning and securing the bulb relative to the air handling equipment apparatus.

According to the present invention a one-piece molded strain relief structure for an electrical conductor is provided which includes a body portion having a tortuous path directly molded therein for receiving and guiding the conductor. The tortuous path includes an entrance and exit and further includes at least two changes in direction therealong. In a preferred embodiment the tortuous path is substantially S-shaped and is adapted to receive an electrical conductor having a flat cross section. The tortuous path is configured to confine the flat electrical conductor in a first orientation adjacent the entrance thereof and to cause twisting of the conductor to a second orientation angularly disposed from the first orientation as it approaches the exit thereof. A guide is provided adjacent the exit for imparting a sharp bend in the conductor as it passes therefrom.

The indoor section includes an evaporator coil at the front of the basepan, and a condensate pan mounted in the basepan under the evaporator coil. An evaporator fan scroll is mounted in the basepan rearwardly of the evaporator coil and is positioned by cooperation with the condensate pan and the partition. A control box is mounted in the indoor section overlying a portion of the condensate pan and has an upper surface which engages the horizontal rib formed in the partition. An indoor fan motor is mounted within the control box and drives an indoor fan which has an axis of rotation which extends parallel to the basepan and the partition, and which is spaced from the interior surface of the scroll. The scroll further comprises fan support structure at the end opposite the control box to thereby support the fan for rotation. A fan support bracket engages the fan support structure on the scroll and is also provided with an upper surface having a portion adapted to engage the horizontally extending rib of the partition.

Low profile room air conditioner indoor section construction

An air conditioning unit including a basepan upon which is mounted an indoor section in communication with the space to be conditioned. The indoor section includes an indoor heat exchanger and means for circulating air to be conditioned in heat exchange relation with the indoor heat exchanger. Also mounted on the basepan is an outdoor section in communication with ambient air and including an outdoor heat exchanger and a compressor. A partition forms a part of the basepan and divides the air conditioning unit to separate the indoor section from the outdoor section. The partition is provided with a partition opening therethrough. Refrigerant carrying lines extend between the indoor section and the outdoor section through the partition opening. An elongated section of insulating material circumferentially encloses the refrigerant tubes in the region in which they pass through the partition opening. The insulating material is taped to the refrigerant tubes at the end thereof which is on the side of the partition opening adjacent to the outdoor section thereof.
