Definitions

• a dehumidifier is an appliance that sucks damp air into a case, allows the sucked damp air to pass through a heat exchanger to remove moisture from the sucked air, and discharge the air from which the moisture is removed to an indoor space, thereby lowering the humidity in the indoor space.
• a de- humidifier including: a main body case having an air inlet through which external air flows; a barrier dividing an inner space of the main body case; an absorption member provided on one side of the barrier to adsorb moisture contained in air while rotating in low speed; a recovery assembly for delivering circulating air that exchanges heat with the external air at a front of the barrier; a heater assembly for receiving and heating circulating air delivered from the recovery assembly; a high temperature duct provided on one side of the heater assembly to guide a portion of air that has passed through the adsorption member to an inside of the heater assembly; and a plurality of heat exchangers for receiving circulating air discharged from the heater assembly, and constituting a closed circuit together with the recovery assembly to allow the circulating air to circulate through the closed circuit.
• a high temperature duct for guiding air to allow a portion of heated air that has flowed from an outside and passed through an adsorption member to flow into a heater assembly is further provided on the rear side of the heater assembly. Therefore, a load applied to the heater assembly relatively reduces, and dehumidification efficiency improves.

• the side heat exchanger 220 is installed at the right side of the front heat exchanger 210. Like the inner and front heat exchangers 220 and 200, the side heat exchanger 220 functions to allow the interior and exterior airs to heat-exchange with each other.
• upper and lower coupling guides 320 and 322 for fixing the side heat exchanger 220 are formed long horizontally at front upper and lower ends of the right extension surface 130b of the barrier 130, respectively. That is, the upper coupling guide 320 is formed long horizontally at the vicinity of the upper end of the right extension surface 130b, and the lower coupling guide 322 is formed long horizontally at the vicinity of the lower end of the right extension surface 130b.
• an upper couplin groove 320' and a lower coupling groove 322" are formed in right sides of the upper coupling guide 320' and the lower coupling guide 322.
• Coupling members 334 and 336 are inserted and coupled in the upper coupling groove 320' and the lower coupling groove 322" respectively. Therefore, the insides of the upper and lower coupling grooves 320' and 322" are threaded to receive screws.
• the adsorption motor assembly 176 further includes coupling portions 177 for fixing the adsorption assembly 180. That is, the coupling portions 177 protrude to the upper side and lower side at the upper and lower ends of the adsorption assembly 180.
• the coupling portions 177 include a pair of screw through holes 177' for receiving screws.
• the adsorption motor assembly 176 and the inner heat exchanger 200 are mounted on the barrier 130. That is, FlG. 10 illustrates the adsorption motor assembly 176 is inserted and mounted in the adsorption motor receiving portion 138, and the inner heat exchanger 200 is closely fixed at the right portion of the rearward recess 132.
• FIG. 11 is a perspective view of a high temperature duct according to an embodiment of the present invention
• FIGS. 12 and 13 are front and rear perspective views, respectively, illustrating a hot air guide, a heater assembly, and a high temperature duct are mounted on an adsorption frame according to an embodiment of the present invention.
• a passage through which high temperature air can flow is formed inside the high temperature duct 178.
• a high temperature inlet 178' and a high temperature outlet 178" are formed at the lower and upper ends of the high temperature duct 178, respectively.
• the high temperature inlet 178' is formed relatively larger than the high temperature outlet 178". That is, referring to FlG. 11, the high temperature duct 178 has a width that gradually increases from the upper end to the lower end. This is because the high temperature outlet 176" should be inserted to the right end (in FlG. 12B) of the heater inlet 174 of the heater assembly 170, and the high temperature inlet 178' may have a size corresponding to the lower end length of the heater assembly 170.
• a first overheating prevention member Hl is provided on the surface of the heater assembly 170. That is, referring to FlG. 13, the first overheating prevention member Hl is formed on the rear side of the heater assembly 170 to control power supplied to the heater (not shown) provided to the heater assembly 170. That is, the first overheating prevention member Hl measures the temperature of the surface of the heater assembly 170 to turn on/off power supplied to the heater.
• the first overheating prevention member Hl includes an automatic temperature control unit having bi-metal. Therefore, the first overheating prevention member Hl turns off power supplied to the heater assembly 170 when the temperature of the surface of the heater assembly 170 is greater than a predetermined temperature, and controls power to be supplied to the heater assembly 170 when the temperature of the surface of the heater assembly 170 is smaller than the predetermined temperature.
• the second overheating prevention member H2 includes a temperature disk H2' and a temperature fuse H2".
• the temperature disk H2' is configured to operate at a relatively lower temperature than an operating temperature of the first overheating prevention member Hl. That is, since the hot air guide 192 emits a relatively small amount of heat compared to the heater assembly 170, metal used for a bi-metal of the temperature disk H2' is formed of a material more sensitive to heat compared to the material used for a bi-metal of the first overheating prevention member Hl.

• FIGS. 15 and 16 are exploded perspective views of the first heat exchange unit 222, second heat exchange unit 224, and third heat exchange unit 226 constituting the side heat exchanger 220 seen from the right and left sides, respectively.
• the first, second, and third heat exchange units 222, 224, and 226 are coupled to each other using coupling members 340 and 342. At least one of the first, second, and third heat exchange units 222, 224, and 226 is fixedly mounted on the barrier 130.
• the upper end of at least one of the first, second, and third heat exchange units 222, 224, and 226 can be fixed in the barrier 130 using coupling members 224 and 336.
• an upper through hole 330' is formed in the upper coupling portion 330, and a lower through hole 332' is formed in the lower coupling portion 332.
• the coupling members 334 and 336 pass through the upper through hole 330' and the lower through hole 332'.
• the side heat exchanger 220 is fixedly mounted on the barrier 130 using the coupling members 334 and 336. That is, as illustrated, the side heat exchanger 220 is fixed on the barrier 130 using the coupling members 334 and 336 such as screws.
• the coupling members 334 and 336 are not limited to screws, but other coupling members can be used.
• the coupling members 334 and 336 include the upper coupling member 334 inserted and coupled in the upper coupling groove 320' of the upper coupling guide 320, and the lower coupling member 336 inserted and coupled in the lower coupling groove 322' of the lower coupling guide 322. Also, the upper coupling member 334 and the lower coupling member 336 pass through the upper through hole 330' and the lower through hole 332' of the first heat exchange unit 222, respectively, and are coupled to the upper coupling groove 320' and the lower coupling groove 322', respectively.
• the coupling members 340 and 342 include coupling protrusions 340 and protrusion coupling pipes 342 formed on one sides of the heat exchangers 222, 224, and 226 to correspond to each other. That is, the protrusion coupling pipe 342 and the coupling protrusion 340 are formed on the left side of the first heat exchange unit 222 and the right side of the second heat exchange unit 224, respectively, to correspond to each other and are coupled to each other. Also, the protrusion coupling pipe 342 and the coupling protrusion 340 corresponding to each other are formed on the left side of the second heat exchange unit 224 and the right side of the third heat exchange unit 226, respectively, and coupled to each other. Also, the protrusion coupling pipe 342 and the coupling protrusion 340 are formed on each corner of one sides of the heat exchangers 222, 224, and 226.
• the protrusion coupling pipe 342 protrudes to the left from the front lower end on the left side of the first heat exchange unit 222.
• the protrusion coupling pipe 342 is the same as the protrusion coupling pipe formed at the rear upper end on the left side of the above-described first heat exchange unit 222.
• a recovery fan (not shown) provided inside the recovery assembly 160 rotates to generate flowing of circulating air in the inside of the heat exchangers 200, 210, and 220.
• the heater (not shown) provided inside the heater assembly 170 is also driven by the external power to emit hot air.
• a passage of the circulating air flowing through the heat exchangers 200, 210, and 220 constitutes a closed circuit. That is, unlike the above-described air (i.e., air introduced from the indoor space to the dehumidifier), the circulating air in the heat exchangers 200, 210, and 220 is not replaced but continuously circulate through the closed passage to exchange heat with the external air.
• the circulating air directed from the recovery assembly 160 is, as indicated by D, introduced into the heater assembly 170 through the heater inlet 174 connected to the recovery outlet 164.
• the circulating air directed into the front heat exchanger 210 exchanges heat with the external air. That is, as described above, the circulating air exchanges heat with the external air which is introduced through the air inlet 128 and flows along an external side of the front heat exchanger 210.
• the circulating air that has passed through the front heat exchanger 210 is, as indicated by D, introduced into the side heat exchanger 220. That is, the circulating air in the front heat exchanger 210 is directed to the third heat exchange unit 226 through the front outlet 214 and subsequently introduced into the third heat exchanger 226 through the third inlet 226b. Subsequently, the circulating air passes through the second heat exchanger 224 and then to the first exchange unit. At this point, the external air outside the side heat exchanger 220 takes the heat from the circulating air and thus the moisture contained in the circulating air is condensed.
• the air that has passed through the side heat exchanger 220 is introduced into the inner heat exchanger 200.
• the circulating air discharged through the first outlet 222a of the first heat exchanger 222 is, as indicated by D, introduced into the barrier 130 through the air inlet 146 formed on the barrier 130.
• the circulating air is, as indicated by D, introduced into the inner heat exchanger 200 through the air outlet 146 and the inner inlet 202.
• the circulating air introduced into the inner heat exchanger 200 exchanges heat with the external air. That is, after passing through the adsorption member 182, the circulating air exchanges heat with the air directed to a rear side of the barrier 130 through the central through hole 134 of the barrier 130. [207] Accordingly, the circulating air in the inner heat exchanger 200 is cooled and thus the moisture contained in the circulating air is condensed and discharged downward.
• the circulating air that has passed through the inner heat exchanger 200 is, as indicated by D, introduced into the recovery assembly 160. That is, since the inner inlet 204 of the inner heat exchanger 200 is coupled to the recovery inlet 162 of the recovery assembly 160, the circulating air in the inner heat exchanger 200 is introduced into the recovery assembly 160.
• the condensed water that is temporarily collected in the drain pan 250 falls into the water tank 300 through a hole formed to pass through a side of the drain pan 250.
• a high temperature fan 178a for forcing air introduced through the high temperature inlet 178' to flow upward is provided inside the high temperature duct 178.
• a high temperature motor 178a is provided to the left side of the high temperature fan 178a to provide rotational power to the high temperature fan 178a.
• a portion of external air that has passed through the adsorption member 182 is introduced into the high temperature duct 178 by rotation of the high temperature fan 178a and forced to flow into the heater assembly 170 through the high temperature outlet 178".
