Definitions
- the present invention relates generally to air conditioning apparatus and more particularly to electrically actuated dehumidifiers.
- dehumidifiers are equipped with relatively heavy operative components, such as an evaporator coil, a condenser, a compressor and a fan motor. Typically, these components are mounted upon internal support members and are surrounded by one or more external panels or shells.
- the support members were usually formed from a plurality of metal components which required considerable assembly time, were subject to corrosion, were electrically conductive and permitted water to pass through gaps therebetween. The lack of unity in the internal support structure resulted in one or more of the internal support members being affixed to an exterior cover member.
- ice collects on the evaporator fins and coils.
- the compressor is turned off before air flow through the evaporator is substantially impeded by the ice.
- a defrost cycle is provided wherein the fan is on, the compressor is off and relatively warm air passes through the evaporator to thaw the ice.
- the defrost cycle was initiated when the evaporator reached a selected low temperature, such as 27° F, and ended at a selected high temperature, such as 37° F. At that point, the compressor resumed operation, if the desired humidity level had not been reached.
- a selected low temperature such as 27° F
- a selected high temperature such as 37° F.
- Portable dehumidifiers are, by virtue of their portability, subject to certain drawbacks or considerations that are less significant in standard sized dehumidifiers.
- One of the most important considerations is the presence of the portable dehumidifier in living areas which would be stained or otherwise damaged if water is spilled.
- the water receptacle in a portable dehumidifier is typically smaller than the one in a standard unit and is likely to require more frequent emptying. To do so, the user must carry the full receptacle across flooring, carpeting and furniture to a sink, bath tub or other drain site.
- a relatively large opening was provided at the top of the receptacle for receiving the condensate from the evaporator coils. As a result, removing and carrying the full receptacle to the drain without spilling water was difficult.
- the present air conditioning apparatus was invented in an effort to eliminate or substantially reduce the above-described drawbacks and limitations of previous portable dehumidifiers.
- the present inventors employed the following components in devising their new electrically powered air conditioning apparatus; namely, a removable water receptacle, a condenser, an evaporator, a fan, a fan motor, a compressor, a humidity sensor, a temperature sensor, an electrical circuit extending between the electrically actuated components, a circuit control device, a pair of exterior half-shells and a handle disposed on at least one of the exterior half-shells.
- the present invention represents an improvement which basically comprises: a mounting member formed with a generally horizontally disposed base adapted to receive the exterior half-shells, the water receptacle and the compressor and with a partition wall extending generally vertically from the base, said partition wall having a lower portion which separates the base into a water receptacle area and a compressor area and which defines a substantially impermeable barrier to the movement of water therebetween, an intermediate portion adapted to carry the condenser, the evaporator, the fan and the fan motor, and an upper portion adapted to support the handle.
- the present invention preferably includes the following features: the above-described mounting member is unitarily molded from synthetic resin material; a detection device is provided to generate signals corresponding to selected intermediate and maximum water levels in the water receptacle; a clock device is connected to the circuit control device with the circuit control device being responsive to the temperature sensor and the clock device to maintain operation of the compressor for a selected period of time after a selected low temperature is reached; at least two substantially spaced apart air outlets are provided on one of the exterior half-shells for exhausting the air in at least two substantially different directions; and a substantially restricted opening is provided in the water receptacle for receiving and discharging water.
- Important objects of the present invention are as follows: to provide a dehumidifier with an internal support member by which the dehumidifier may be carried; to provide a dehumidifier which may be operated during production and/or maintenance with the external covers removed; to eliminate or substantially reduce corrosion and the possibility of short circuiting caused by water reaching electrical components, and particularly high voltage electrical components; to permit the dehumidifier to be placed in close proximity towalls, furniture and other objects without hindering the flow of air through the dehumidifier; to eliminate or substantially reduce the likelihood of spillage from the water reservoir; to provide the user with an indication when the water receptacle is nearly full; and to improve the efficiency and life of the compressor.

- the compressor is of the reciprocating motor type, resistance start, induction run.
- the control circuit board 28 is provided with a series of light-emitting diodes (LEDs) which are visible through a touch panel 31 (FIG. 2) mounted on an upper exterior surface of the dehumidifier.
- LED 32 flashes on and off when the water level in the receptacle 26 reaches 80% capacity and remains constantly on when the receptacle 26 is completely full.
- LED 33 is illuminated when the defrost cycle is on.
- LED 34 is illuminated when the fan is operating at high speed and the compressor is off.
- LED 35 is illuminated when the fan is operating at low speed and the compressor is on.
- LED 36 is illuminated when the fan is operating at high speed and the compressor is on.
- LED 37 is illuminated when a 30% relative humidity level is selected.
- LEDs 38-41 are illuminated when 40, 50, 60, and 70% relative humidity levels are respectively selected.
- Switch 42 controls the fan/compressor selections indicated by LED's 34-36.
- Switch 43 controls the humidity level selections indicated by LED's 37-41.
- Switch 44 turns the present dehumidifier on and off.
- a unitary molded mounting member 45 is formed with a generally horizontal base portion 46 and a generally vertical partition wall 47.
- a front exterior half-shell 48 (FIGS. 1, 3, 6) is removably mounted on the base portion 46 and is formed with a movable access panel 49 and with an air inlet 50.
- An upper corner portion 51 on the front shell 48 is removable therefrom and is attached to an air filter 52 slidably mounted in grooves on opposite inner surfaces on the front shell.
- a rear exterior half -shell 53 (FIGS . 3 , 5 , 6 ) is removably mounted on the base 46 and is provided with substantially spaced apart air outlets 54, 55, 56, which direct the exhaust air in substantially different directions.
- An inwardly projectinghandle 57 (FIGS. 5, 6) is formed in an upper portion of the external half-shell for insertion into a handle-supporting cavity 58 (FIGS. 6,7) formed in an upper portion 59 of the partition wall 47.
- the mounting member 45 and the front and rear half-shells 48 and 53 are integrally molded from synthetic resin material.
- the base 46 is adapted to receive the front and rear shells 48, 53, the water receptacle 26 and the compressor 21.
- a lower portion 60 of the partition wall 47 separates the base into a water receptacle area 61 and a compressor area 62 and defines a substantially impermeable barrier to the movement of water between these areas 61, 62.
- An intermediate portion 63 of the partition wall 47 is adapted to carry the condenser 24, evaporator 25, fan 22, and fan motor 23.
- the evaporator 25 is mounted on a drip pan 64 which is secured to the intermediate portion 63 of the partition wall.
- the drip pan is molded from synthetic resin material and is integrally formed with an apertured drain trough 65.
- the water receptacle 26 is blow-molded from synthetic resin material and is removably mounted in an inwardly projecting shelf 66 on the front access panel 49.
- the receptacle is formed with a substantially restricted opening 67 for receiving and dispensing water.
- the opening 67 is provided in the upper surface of the receptacle and is positioned so that it is directly below the apertured drain trough 65 when the front access panel 49 is closed.
- the upper surface of the water receptacle 26 is formed at an end opposite the water-receiving opening 67 with a second aperture adapted to receive a float assembly 68. As indicated in FIG.
- the float assembly 68 includes a water-permeable cage or sleeve 69 and a float 70 made of a buoyant material such as styrofoam.
- the cage 69 consists of a generally circular floor and a generally cylindrical wall, each having pores or voids therein to allow water to penetrate the cage 69.
- the wall has a lip 71 that overhangs the outer edge of the second aperture in the receptacle 26 to secure the cage in a desired position.
- the float 70 which is generally bullet-shaped, is vertically movable within the cage 69 in response to the water level in the reservoir.
- a relatively wide circumferential groove is formed in the outer surface of the float 70; and an inwardly projecting, circular groove-engaging lip is formed in the sleeve to prevent the float from escaping.
- an armature 72 is pivotally mounted on the partition wall 47.
- the armature includes a forwardly projecting finger 73 which is disposed to engage the float 70 when the water receptacle is in place (FIG. 9B).
- Three electronically detectable members, 74A-C, preferably magnets, are disposed in spaced relation to one another on the armature 72 and the finger 73.
- a pair of relatively spaced-apart electronic sensors 75, 76, such as magnetic reed switches or Hall Effect sensors, are mounted on the partition wall behind the armature 72.
- the sensors 75, 76 are positioned on the partition wall and the magnets 74A-C are positioned on the armature 72 and finger 73 in such a manner that only one magnet/sensor alignment can occur at any given time and so that the alignment is indicative of the water level in the receptacle 26 or the position of the receptacle, as described below.
- FIG. 9A illustrates the condition in which the receptacle 26 is either not in place in the access door 49 or the access door is not completely closed. In either instance, the magnet 74C in the finger 73 is aligned with the upper sensor 76 and the control circuit 28 will not permit the compressor to operate.
- FIG. 9B illustrates the condition in which the receptacle 26 is disposed in an operative position, and is either empty or less than sufficiently full for the water level to reach the float 70.
- the finger 73 engages the recessed float 70 and is elevated by the float, thereby breaking the contact between the finger magnet 74C and the upper sensor 76.
- the armature 72 is slightly elevated, neither of the other magnets 74A, 74B is aligned with the lower sensor 75.
- the control circuit 28 responds by no longer impeding the compressor 21.
- FIG. 9C illustrates the condition where the water level 77 reaches approximately 80 percent of the receptacle's capacity.
- the float 70 rises in response to the elevated water level, thereby causing the armature 72 to pivot further upwardly so that the innermost magnet 74A is aligned with the lower sensor 75.
- the control circuit causes LED 32 (FIG. 2) to flash intermittently but permits the dehumidifier to continue operating in its normal mode.
- FIG. 9D illustrates the condition in which the water level 77 reaches the top of the receptacle 26.
- the float 70 rises to its highest position, thereby causing the armature 72 to pivot upwardly and align the intermediate magnet 74B with the upper sensor 76 .
- the control circuit causes the "Reservoir full" LED 32 to light continuously and suppresses the compressor.
- the source code for the control circuit microprocessor accompanies this application and is identified as Appendix A.
- a temperature sensor 81 is attached to the evaporator coil 25.
- a timing device 77 (FIG. 10) is provided on the control circuit board 28.
- the control circuit is programmed so that when the evaporator coil reaches a selected temperature, preferably 27 degrees F, the control circuit initiates the clock 78. Once the clock has run for a selected period of time, preferably 45 minutes, the control circuit stops the compressor 21 while the fan 22 and its associated motor 23 continue to operate in order to defrost the evaporator coils 25. During the defrost period, the associated LED 33 is illuminated.
- the air outlets 54-56 are substantially identical in size and shape.
- a pair of detachable coverplates 79, 80 are provided and are formed to provide a snap-fit engagement with portions of the rear half-shell 53 disposed in surrounding relation to the outlets 54-56.
