Abstract
A method for controlling a fan of a dehumidifier includes performing a first step of obtaining an ambient temperature, an exhaust temperature, and a delta temperature that is a difference between the ambient temperature and the exhaust temperature. The method further include determining, after performing the first step, whether the delta temperature is within a delta temperature range. If the delta temperature is within the delta temperature range, the method proceeds back to the first step. If the delta temperature is not within the delta temperature range, the method performs a second step of determining an adjusted fan speed using the delta temperature. The method further includes performing, after performing the second step, a third step of setting the fan speed to the determined adjusted fan speed.

In some embodiments, wall 380 extends from an inside bottom surface of cabinet 105 to a height that is less than a height of primary condenser 350. In some embodiments, wall 380 is less than one-fourth the height of primary condenser 350. In general, wall 380 forms at least a portion of drain pan 360 and prevents water from exiting portable dehumidifier 100 via airflow outlet 115. As water is removed from airflow 101 via dehumidification system 300, it falls via gravity to the bottom of cabinet 105 and into drain pan 360 where is may be later removed from portable dehumidifier 100. By having wall 380 being integrated into cabinet 105 and forming a portion of drain pan 360, valuable space may be saved within portable dehumidifier 100. This further helps reduce the overall size and footprint of portable dehumidifier 100.
In some embodiments, wall 380 wraps at least partially around a bottom portion 321 of compressor 320. This is best illustrated in FIGURE 3D.

Once pivoting handle 135 has been unlocked, some embodiments of portable dehumidifier 100 utilize a torsion spring (not illustrated) to pivot pivoting handle 135 upwards toward the operator. The operator grasps pivoting handle 135 and pivots pivoting handle 135 upwards until it stops into an engaged position (e.g., approximately fifteen degrees above vertical). The engaged position of pivoting
13 handle 135 is illustrated in FIGURES 5-6 and 7B. Pivoting handle 135 is locked into its engaged position by a cam arm 720, described in more detail below. Once pivoting handle 135 is in its engaged position, the operator may tilt portable dehumidifier 100 towards front side 106C and transport portable dehumidifier 100 using wheels 130. Once no longer needed, pivoting handle 135 may be pivoted downwards and back into its stored position (e.g., flat against back side 106D). Once in its stored position, latch 410 automatically rotates to engage pivoting handle 135 and lock it in its stored position (FIGURE 7F).
As illustrated in FIGURES 7A-7G, some embodiments of pivoting handle 135 include a cross member 710, two extension members 715, and a cam arm 720. Cross member 710 is any appropriate shape that allows for an operator to hold cross member 710 while transporting portable dehumidifier 100. In some embodiments, cross member 710 includes a material (e.g., paint) or surface design that makes pivoting handle 135 suitable for gripping by an operator.
In some embodiments, cross member 710 may be attached to extension members 715 using any appropriate fastener (e.g., screws, bolts, etc.) or may be permanently attached to extension members 715 using, for example, welding. Cross member 710, extension members 715, and cam arm 720 may be made of any appropriate material such as metal or plastic.
In some embodiments, cam arm 720 includes a spring arm 730, a clearance hole 740, an aperture 755 for a pivot pin 760, and a compression gap 780. Spring arm 730 may include an indentation 790 and a straight edge 735. Pivot pin 760, which may be any appropriate fastener such as a shoulder bolt, is inserted through aperture 755 and into a pivot plate 750 in order to secure cam arm 720 to cabinet 105 and to provide a pivot point for cam arm 720 to pivot. Indentation 790 and straight edge 735 of spring arm 730 engages with a locking pin 770 at various times while pivoting handle 135 is being pivoted. Locking pin 770 is any appropriate fastener or protrusion coupled to pivot plate 750. In some embodiments, a bearing 775 is coupled to locking pin 770 and is configured to contact spring arm 730 and rotate about locking pin 770.
Spring arm 730 may have any appropriate shape to allow cam arm 720 to engage locking pin 770 at various points while pivoting handle 135 is pivoting upwards. In some embodiments, spring arm 730 is a finger-shaped protrusion as illustrated in and includes indentation 790 at an end of spring arm 730. Indentation 790 is any appropriate feature at the end of spring arm 730 to engage with locking pin 770 and lock pivoting handle
As illustrated in FIGURES 7A-7G, some embodiments of pivoting handle 135 include a cross member 710, two extension members 715, and a cam arm 720.

Cross member 710, extension members 715, and cam arm 720 may be made of any appropriate material such as metal or plastic.
In some embodiments, cam arm 720 includes a spring arm 730, a clearance hole 740, an aperture 755 for a pivot pin 760, and a compression gap 780. Spring arm 730 may include an indentation 790 and a straight edge 735. Pivot pin 760, which may be any appropriate fastener such as a shoulder bolt, is inserted through aperture 755 and into a pivot plate 750 in order to secure cam arm 720 to cabinet 105 and to provide a pivot point for cam arm 720 to pivot. Indentation 790 and straight edge 735 of spring arm 730 engages with a locking pin 770 at various times while pivoting handle 135 is being pivoted. Locking pin 770 is any appropriate fastener or protrusion coupled to pivot plate 750. In some embodiments, a bearing 775 is coupled to locking pin 770 and is configured to contact spring arm 730 and rotate about locking pin 770.
Spring arm 730 may have any appropriate shape to allow cam arm 720 to engage locking pin 770 at various points while pivoting handle 135 is pivoting upwards. In some embodiments, spring arm 730 is a finger-shaped protrusion as illustrated in and includes indentation 790 at an end of spring arm 730. Indentation 790 is any appropriate feature at the end of spring arm 730 to engage with locking pin 770 and lock pivoting handle
14 135 in its engaged position (see FIGURE 7B). Compression gap 780 is adjacent to spring arm 730 and is located between spring arm 730 and aperture 755. Compression gap 780 is any appropriate shaped gap in cam arm 720 that allows spring arm 730 to compress towards pivot pin 760 and therefore act as a spring. This provides positive feedback and resistance to pivoting handle 135 as it is pivoted upwards to it engaged position.
Clearance hole 740 is any gap in cam arm 720 that permits cam arm 720 to clear locking pin 770 when pivoting handle 135 is in the stored position (see FIGURE
7C). In other words, clearance hole 740 prevents cam arm 720 from contacting locking pin 770 when pivoting handle 135 is pivoted from its engaged position to its stored position. Clearance hole 740 may have any appropriate shape, but is generally larger than locking pin 770. Clearance hole 740 is located between an end of extension member 715 and pivot pin 760.
In operation, pivoting handle 135 is typically in the stored position when not in use (see FIGURE 7C). In the stored position, pivoting handle 135 lays flat against back side 106D
of cabinet 105. In addition, as illustrated in FIGURE 7C, clearance hole 740 prevents cam arm 720 from contacting locking pin 770 while pivoting handle 135 is in the stored position.
When an operator desires to move portable dehumidifier 100 to a new location, the operator may push locking latch 410 to the side (see FIGURE 7G) to unlock pivoting handle 135 from its stored position and enable pivoting handle 135 to pivot upwards toward top side 106A.
The operator then grasps pivoting handle 135 and pivots pivoting handle 135 upwards. While pivoting handle 135 is being pivoted upwards, straight edge 735 of spring arm 730 begins contacting locking pin 770 (see FIGURE 7D). This permits spring arm 730 to slide along locking pin 770. While sliding along locking pin 770, spring arm 730 begins compressing into compression gap 780. This spring action of spring arm 730 provides positive feedback and resistance to pivoting handle 135 during pivoting. Once pivoting handle 135 is pivoted upwards further, indentation 790 will engage locking pin 770. This stops the pivoting of pivoting handle 135 and locks pivoting handle 135 into its engaged position (see FIGURE
7E). At the engaged position, indentation 790 of spring arm 730 provides enough holding strength to hold up the weight of pivoting handle 135 without requiring the operator to hold up pivoting handle 135. In addition, the spring action of spring arm 730 and the shape of indentation 790 allows pivoting handle 135 to "pop" into its engaged position.
This provides confirmation to the operator that pivoting handle 135 has been sufficiently pivoted into the
Clearance hole 740 is any gap in cam arm 720 that permits cam arm 720 to clear locking pin 770 when pivoting handle 135 is in the stored position (see FIGURE
7C). In other words, clearance hole 740 prevents cam arm 720 from contacting locking pin 770 when pivoting handle 135 is pivoted from its engaged position to its stored position. Clearance hole 740 may have any appropriate shape, but is generally larger than locking pin 770. Clearance hole 740 is located between an end of extension member 715 and pivot pin 760.
In operation, pivoting handle 135 is typically in the stored position when not in use (see FIGURE 7C). In the stored position, pivoting handle 135 lays flat against back side 106D
of cabinet 105. In addition, as illustrated in FIGURE 7C, clearance hole 740 prevents cam arm 720 from contacting locking pin 770 while pivoting handle 135 is in the stored position.
When an operator desires to move portable dehumidifier 100 to a new location, the operator may push locking latch 410 to the side (see FIGURE 7G) to unlock pivoting handle 135 from its stored position and enable pivoting handle 135 to pivot upwards toward top side 106A.
The operator then grasps pivoting handle 135 and pivots pivoting handle 135 upwards. While pivoting handle 135 is being pivoted upwards, straight edge 735 of spring arm 730 begins contacting locking pin 770 (see FIGURE 7D). This permits spring arm 730 to slide along locking pin 770. While sliding along locking pin 770, spring arm 730 begins compressing into compression gap 780. This spring action of spring arm 730 provides positive feedback and resistance to pivoting handle 135 during pivoting. Once pivoting handle 135 is pivoted upwards further, indentation 790 will engage locking pin 770. This stops the pivoting of pivoting handle 135 and locks pivoting handle 135 into its engaged position (see FIGURE
7E). At the engaged position, indentation 790 of spring arm 730 provides enough holding strength to hold up the weight of pivoting handle 135 without requiring the operator to hold up pivoting handle 135. In addition, the spring action of spring arm 730 and the shape of indentation 790 allows pivoting handle 135 to "pop" into its engaged position.
This provides confirmation to the operator that pivoting handle 135 has been sufficiently pivoted into the
15 engaged position. Once pivoting handle 135 is in its engaged position, the operator may tilt portable dehumidifier 100 towards front side 106C and transport portable dehumidifier 100 using wheels 130. Once no longer needed, pivoting handle 135 may be pivoted downwards and back into its stored position (e.g., flat against back side 106D). Once in its stored position, latch 410 automatically rotates to engage pivoting handle 135 and lock it in its stored position (see FIGURE 7F).

FIGURES 8C-8D, which are discussed in more detail below, provide more details on specific embodiments of wheel mounting bracket assembly 810.
As illustrated in FIGURES 8C-8D, some embodiments of wheel mounting bracket assembly 810 include an inside member 820, an outside member 830, a bottom member 840, and a top member 865. Inside member 820 is installed proximate to one of the sides of cabinet 105 and is closer to the interior of cabinet 105 than outside member 830. In some embodiments, inside member 820 includes a first axle aperture 870 that is configured to accept one end of axle 805. Axle 805 is generally configured to secure one of wheels 130 to cabinet 105.
In some embodiments, bottom member 840 is coupled to an end of inside member that is opposite from top member 865. When wheel mounting bracket assembly 810 is installed in portable dehumidifier 100, bottom member 840 contacts a portion of bottom side 106B of cabinet 105. In some embodiments, bottom member 840 includes one or more
16 mounting apertures 845 that are configured to permit one or more fasteners to couple wheel mounting bracket assembly 810 to bottom side 106B of cabinet 105. For example, some embodiments of bottom member 840 include two mounting apertures 845 that permit two fasteners (e.g., screws or bolts) to couple wheel mounting bracket assembly 810 to cabinet 105.
In some embodiments, top member 865 couples inside member 820 to outside member 830. In some embodiments, top member 865 includes one or more locating pins 860 that are configured to be inserted into one or more locating apertures (not illustrated) in cabinet 105.
For example, some embodiments of wheel mounting bracket assembly 810 include two threaded locating pins 860 (e.g., bolts, screws, or pins that arc otherwise coupled to top member 865) that may be inserted into locating apertures of cabinet 105. The locating apertures may be any appropriate receptacle for locating pins 860 and function to align and secure wheel mounting bracket assembly 810 within cabinet 105. In some embodiments, top member 865 is two separate portions: one portion that is coupled to an end of inside member 820 that is opposite to bottom member 840, and a second portion that is coupled to an end of outside member 830 that is opposite second axle aperture 835. In such embodiments, wheel mounting bracket assembly 810 is formed from two separate pieces that are welded or otherwise coupled together: inside member 820 and outside member 830. In other embodiments, wheel mounting bracket assembly 810 is a single bracket that is formed from a single piece of metal. An example of such embodiments is discussed below in reference to FIGURES 9A-9B.
In some embodiments, wheel mounting bracket assembly 810 includes an outside member 830 that is closer to an outside of cabinet 105 with respect to inside member 820 when wheel mounting bracket assembly 810 is installed in cabinet 105. In some embodiments, outside member 830 includes a second axle aperture 835 that is configured to accept another end of axle 805. In some embodiments, outside member 830 includes a weld nut 850 coupled to an outside surface of outside member 830 as illustrated.
Weld nut 850 may be used to secure axle 805 and may include a threaded aperture that is aligned with second axle aperture 835. In some embodiments, outside member 830 is shorter than inside member 820 as illustrated in the figures.
In some embodiments, top member 865 couples inside member 820 to outside member 830. In some embodiments, top member 865 includes one or more locating pins 860 that are configured to be inserted into one or more locating apertures (not illustrated) in cabinet 105.
For example, some embodiments of wheel mounting bracket assembly 810 include two threaded locating pins 860 (e.g., bolts, screws, or pins that arc otherwise coupled to top member 865) that may be inserted into locating apertures of cabinet 105. The locating apertures may be any appropriate receptacle for locating pins 860 and function to align and secure wheel mounting bracket assembly 810 within cabinet 105. In some embodiments, top member 865 is two separate portions: one portion that is coupled to an end of inside member 820 that is opposite to bottom member 840, and a second portion that is coupled to an end of outside member 830 that is opposite second axle aperture 835. In such embodiments, wheel mounting bracket assembly 810 is formed from two separate pieces that are welded or otherwise coupled together: inside member 820 and outside member 830. In other embodiments, wheel mounting bracket assembly 810 is a single bracket that is formed from a single piece of metal. An example of such embodiments is discussed below in reference to FIGURES 9A-9B.
In some embodiments, wheel mounting bracket assembly 810 includes an outside member 830 that is closer to an outside of cabinet 105 with respect to inside member 820 when wheel mounting bracket assembly 810 is installed in cabinet 105. In some embodiments, outside member 830 includes a second axle aperture 835 that is configured to accept another end of axle 805. In some embodiments, outside member 830 includes a weld nut 850 coupled to an outside surface of outside member 830 as illustrated.
Weld nut 850 may be used to secure axle 805 and may include a threaded aperture that is aligned with second axle aperture 835. In some embodiments, outside member 830 is shorter than inside member 820 as illustrated in the figures.
17 In some embodiments, wheel mounting bracket assembly 810 includes multiple gussets 880. For example, some embodiments include one or more first gussets 880 that are located at an edge between inside member 820 and bottom member 840, one or more second gussets 880 that are located at an edge between inside member 820 and top member 865, and one or more third gussets 880 that are located at an edge between outside member 830 and top member 865. In general, gussets 880 give strength and structural support to the various members of wheel mounting bracket assembly 810.
FIGURES 9A-9B illustrate a wheel mounting bracket 910 according to certain embodiments. In general, wheel mounting bracket 910 is similar to wheel mounting bracket assembly 810. However, unlike wheel mounting bracket assembly 810 which may be formed from two separate pieces of metal that are coupled together at top member 865, wheel mounting bracket 910 may be formed from a single piece of metal. This may provide for lower material and assembly costs for portable dehumidifier 100.
FIGURE 10 illustrates a fan control method 1000 that may be used by portable dehumidifier 100, according to certain embodiments. In general, fan control method 1000 provides for a unique method for controlling the speed of fan 117. For each ambient temperature, there is a minimum temperature difference between the exhaust temperature and the ambient temperature that portable dehumidifier 100 will try to maintain by adjusting the speed of fan 117. If the temperature difference falls below the minimum allowed at that ambient temperature, portable dehumidifier 100 will slow the speed of fan 117 to maintain the temperature difference. A particular embodiment of fan control method 1000 is discussed in more detail below in reference to the flow chart illustrated in FIGURE 10.
At step 1002, which is an optional step in some embodiments, method 1000 turns on compressor 320. At step 1004, which may also be an optional step in some embodiments, method 1000 sets the speed of fan 117 to a default fan speed. In some embodiments, the default fan speed may be a maximum fan speed, a minimum fan speed, a fan speed associated with a quiet-mode of portable dehumidifier 100, or any other fan speed between the minimum and maximum fan speed. At step 1006, which may also be an optional step in some embodiments, method 1000 waits a first predetermined amount of time. In some embodiments, the first predetermined amount of time may be zero seconds or less, greater than

FIGURE 10 illustrates a fan control method 1000 that may be used by portable dehumidifier 100, according to certain embodiments.

For each ambient temperature, there is a minimum temperature difference between the exhaust temperature and the ambient temperature that portable dehumidifier 100 will try to maintain by adjusting the speed of fan 117. If the temperature difference falls below the minimum allowed at that ambient temperature, portable dehumidifier 100 will slow the speed of fan 117 to maintain the temperature difference. A particular embodiment of fan control method 1000 is discussed in more detail below in reference to the flow chart illustrated in FIGURE 10.
At step 1002, which is an optional step in some embodiments, method 1000 turns on compressor 320. At step 1004, which may also be an optional step in some embodiments, method 1000 sets the speed of fan 117 to a default fan speed. In some embodiments, the default fan speed may be a maximum fan speed, a minimum fan speed, a fan speed associated with a quiet-mode of portable dehumidifier 100, or any other fan speed between the minimum and maximum fan speed. At step 1006, which may also be an optional step in some embodiments, method 1000 waits a first predetermined amount of time. In some embodiments, the first predetermined amount of time may be zero seconds or less, greater than
18 zero seconds but less than or equal to five minutes, or greater than five minutes but less than or equal to ten minutes. After step 1006, method 1000 may proceed to step 1010.
At step 1010, method 1000 performs a first step of obtaining an ambient temperature, obtaining an exhaust temperature, and calculating or otherwise obtaining a delta temperature which is a difference between the ambient temperature and the exhaust temperature. In some embodiments, the ambient temperature is obtained from a temperature sensor located anywhere within airflow 101 prior to dehumidification system 300, and the exhaust temperature is obtained from a temperature sensor located anywhere within airflow 101 after dehumidification system 300.
After step 1010, method 1000 may proceed to step 1020 where the delta temperature of step 1010 is compared to a predetermined delta temperature range. If the delta temperature of step 1010 is within the delta temperature range, method may proceed to step 1025. Otherwise, if the delta temperature is not within the delta temperature range, method 1000 may proceed to step 1030. In some embodiments, step 1020 includes determining whether the delta temperature of step 1010 is greater than or equal to 20 degrees Fahrenheit (plus or minus 10%) and less than or equal to 23 degrees Fahrenheit (plus or minus 10%). In some embodiments, the delta temperature range is a predetermined a constant range. In other embodiments, the delta temperature range is a variable range based on the ambient temperature.
At step 1025, method 1000 waits a second predetermined amount of time. The second predetermined amount of time may be, for example, zero seconds or less, greater than zero seconds but less than or equal to one minute, greater than one minute but less than or equal to five minutes, or greater than five minutes. After step 1025, method 1000 proceeds back to step 1010.
At step 1030, method 1000 performs a second step of determining an adjusted fan speed using the delta temperature of step 1010. In some embodiments, determining the adjusted fan speed using the delta temperature of this step includes calculating an adjusted delta by subtracting a target delta constant from the delta temperature of step 1010 and then calculating the adjusted fan speed by multiplying the adjusted delta by a fan unit constant.
The target delta constant may be, for example 21.5 degrees Fahrenheit (plus or minus 20%).
In some embodiments, the fan unit constant is a number of fan units per degree Fahrenheit
At step 1010, method 1000 performs a first step of obtaining an ambient temperature, obtaining an exhaust temperature, and calculating or otherwise obtaining a delta temperature which is a difference between the ambient temperature and the exhaust temperature. In some embodiments, the ambient temperature is obtained from a temperature sensor located anywhere within airflow 101 prior to dehumidification system 300, and the exhaust temperature is obtained from a temperature sensor located anywhere within airflow 101 after dehumidification system 300.
After step 1010, method 1000 may proceed to step 1020 where the delta temperature of step 1010 is compared to a predetermined delta temperature range. If the delta temperature of step 1010 is within the delta temperature range, method may proceed to step 1025. Otherwise, if the delta temperature is not within the delta temperature range, method 1000 may proceed to step 1030. In some embodiments, step 1020 includes determining whether the delta temperature of step 1010 is greater than or equal to 20 degrees Fahrenheit (plus or minus 10%) and less than or equal to 23 degrees Fahrenheit (plus or minus 10%). In some embodiments, the delta temperature range is a predetermined a constant range. In other embodiments, the delta temperature range is a variable range based on the ambient temperature.
At step 1025, method 1000 waits a second predetermined amount of time. The second predetermined amount of time may be, for example, zero seconds or less, greater than zero seconds but less than or equal to one minute, greater than one minute but less than or equal to five minutes, or greater than five minutes. After step 1025, method 1000 proceeds back to step 1010.
At step 1030, method 1000 performs a second step of determining an adjusted fan speed using the delta temperature of step 1010. In some embodiments, determining the adjusted fan speed using the delta temperature of this step includes calculating an adjusted delta by subtracting a target delta constant from the delta temperature of step 1010 and then calculating the adjusted fan speed by multiplying the adjusted delta by a fan unit constant.
The target delta constant may be, for example 21.5 degrees Fahrenheit (plus or minus 20%).
In some embodiments, the fan unit constant is a number of fan units per degree Fahrenheit
19 (e.g., three fan units per degree Fahrenheit). The fan units may correspond to a number of rotations per minute (RPM) or cubic feet per minute (CFM).
After step 1030, method 1000 may proceed to step 1040 where portable dehumidifier 100 determines whether an evaporator temperature is less than a predetermined temperature.
In some embodiments, the evaporator temperature is a measurement of the temperature of primary evaporator 330 and is performed by any appropriate temperature sensor located proximate to primary evaporator 330. In some embodiments, the predetermined temperature is the water/ice point (i.e., 32 degrees Fahrenheit). If the evaporator temperature is not less than the predetermined temperature, method 1000 proceeds to step 1060.
However, if the evaporator temperature is less than the predetermined temperature, method 1000 proceeds to step 1050.
At step 1050, method 1000 determines if the adjusted fan speed determined in step 1040 is positive (i.e., faster) or negative (i.e., slower) with respect to the current fan speed. If the adjusted fan speed is positive, method 1000 proceeds to step 1060. If the adjusted fan speed is negative or identical, method 1000 proceeds back to step 1010.
At step 1060, method 1000 performs a third step of setting the speed of fan 117 to the adjusted fan speed determined in step 1030. After step 1060, method 1000 proceeds to step 1025 where method 1000 waits the second predetermined amount of time before proceeding back to step 1010.
