Definitions
- the present invention relates to a dehumidifier. More particularly, the present invention relates to dehumidifier in which a flow path of air circulating along a plurality of heat exchangers is formed in a closed-circuit.
- 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.
- the dehumidifier of the related art uses only one heat exchanger to remove the moisture from the air and thus the dehumidifying efficiency is relatively low. Further, when the air passing through the single heat exchanger flows only in a direction from an inlet to an outlet, the dehumudifying reliability is deteriorated.
- JP 2002/326012 discloses a dehumidifier in which a circulation channel is arranged so that at least a portion of the recirculating air at the adsorption side of an adsorbent passes after passing through a heat exchanger and the recirculating
- WO 2006/135171 also discloses a dehumidifier, using a desiccant assembly.
- temperature circulation air passes through a moisture adsorption member containing moisture so that the moisture adsorbed in the moisture adsorption member can be vaporized, thereby making it possible to permanently use the moisture adsorption member.
- the invention provides a dehumidifier as set out in claim 1.
- the circulation air circulating inside of the heat exchangers is heated by the heart and subsequently passes through the moisture adsorption member to vaporize the moisture adsorbed in the moisture adsorption member.
- the moisture adsorption member keeps removing the moisture from the external air. That is, the moisture adsorption member can be semi-permanently used.
- the circulation air remove moisture from the external air and from the adsorption member without using a separate component, the structure of the dehumidifier can be simplified and the dehumidifying efficiency can be improved.

- Fig. 11 is a view illustrating a circulation air flow path in Fig. 2 .
- Fig. 8 external air is introduced into the dehumidifier through a side surface (right surface) of the dehumidifier.
- the air dehumidified in the dehumidifier is discharged to the external side (indoor space) through an upper end of the dehumidifier. That is, the dehumidified air is discharged through the gap between the top panel 120 and other panels.
- blower fan 246 rotates by the torque of the blower motor 240.
- the adsorption assembly 180 rotates 180 by the torque of the adsorption motor 176 and thus the recovery fan (not shown) provided in the recovery assembly 160 also rotates to generate a current of the circulation air.
- the torque generated by the adsorption motor 176 is lower than the torque generated by the recovery motor or the blower motor 240. Therefore, the adsorption assembly 180 rotates with a relatively low RPM.
- the heater (not shown) provided in the heater assembly is driven by the external power to heat the air.
- the external air introduced into the main body case 110 passes through the side heat exchanger 220 as indicated by 2 in Fig. 8 . That is, the air passes successively through the air passing holes provided in the form of slits on the first, second, and third heat exchange units 222, 224, 226.
- the air outside of the side heat exchanger 220 is heat-exchanged with the air inside of the side heat exchanger 220. Accordingly, a temperature of the air outside of the side heat exchanger 220 increases by the hot circulation air in the side heat exchanger 220.
- the air passing through the side heat exchanger 220 passes through the front heat exchanger 210 as shown in Fig. 8 . That is, the external air flows from the right and front sides of the front heat exchanger 210 to the rear side of the front heat exchanger 210. At this point, the airs inside and outside of the front heat exchanger 210 are heat-exchanged with each other.
- the air passing through the front heat exchanger 210 passes through the adsorption member 182 as indicated by 4 in Fig. 8 . Therefore, the moisture contained in the air is adsorbed in a surface of the adsorption member 182. Therefore, the air becomes more dry air.
- the external air passing through the adsorption assembly 180 passes through the inner heat exchanger 200 as indicated by 5 of Fig. 8 .
- the airs inside and outside of the inner heat exchanger 200 are heat-exchanged with each other and thus a temperature of the air is further increased.

- the airflow guide 148 encloses the outer side of the blower fan 246 and has a left end extending upward. Thus, the air discharged by the blower fan 246 flows toward the left upper portion of the barrier 130 as indicated by 7 of Fig. 8 .
- the air flows upward by the upward guide portion 148", and as indicated by (7b), the air passes through the gap between the upper end of the upward guide portion 148" and the left panel 118.
- the air passing through the gap between the upper end of the upward guide portion 148" and the left panel 118 is partly directed to a front side of the barrier 130 through the gap between the upper end of the barrier 130 and the top panel 120. That is, since the gap is formed between the top panel 120 and the upper end of the barrier 130, as indicated by (7c), the air in rear of the barrier 130 flows toward the front side of the barrier 130.
- the air ascended by the airflow guide 148 flows to the front side of the barrier 130.
- the shielding plate 230 in front of the barrier 130 blocks the downward flow of the air so that the air guided upward by the airflow guide 148 cannot be introduced again into the adsorption assembly 180. That is, the air direction upward by the airflow guide 148 flows to the lower side of the shielding plate 230 so as not to be mixed with the air that is being introduced from the external side.
- the air directed upward is dispersed toward the edge of the top panel 120 and discharged through the air outlet 122. That is, as indicated by 8 of Fig. 8 , the air is discharged to the external side through the air outlet 122 defined by the gap between the top panel and the main body case 110.
- the method for discharging the air through the air outlet 122 defined by the gap provided in the form of slits is called a line diffuser method.
- the circulation air path formed along the heat exchangers 200, 210, and 220 is formed in a closed circuit. That is, unlike the above-described air (i.e., air introduced from the indoor space to the dehumidifier), the circulation air in the heat exchangers 200, 210, and 220 is not replaced but continuously circulate along a closed fluid path to heat-exchange with the external air.
- the circulation air directed from the recovery assembly 160 is, as indicated by ⁇ , introduced into the heater assembly 170 through the heater inlet 174 connected to the recovery outlet 164.
- the circulation air introduced into the heater assembly 170 is heated by a heater (not shown) and directed frontward as indicated by ⁇ through the heater outlet 172.
- the circulation air directed frontward through the heater outlet 172 passes through the adsorption member 182.
- the high temperature circulation air discharged through the heater outlet 172 vaporizes the moisture adsorbed in the adsorption member 182.
- the moisture contained in the air passing through the adsorption member 182 is adsorbed in the adsorption member 182.
- the moisture adsorbed in the adsorption member 182 is vaporized and thus removed from the adsorption member 182.
- the adsorption member 182 affected by the high temperature circulation air discharged through the heater outlet 172 becomes a range (fan-shape) corresponding to the heat outlet 172.
- the adsorption member 182 keeps rotating with the low RPM by the adsorption motor 176, the adsorption member 182 entirely contacts the high temperature circulation air discharged through the heater outlet 172 when a predetermined time has elapsed.
- the circulation air passing through the adsorption member 182 is introduced into the hot air guide 192 of the adsorption frame 190 and subsequently directed into the front heat exchanger 210 through the front air inlet 212 of the front heat exchanger 210 as indicated by ⁇ .
- the circulation air directed into the front heat exchanger 210 is heat-exchanged with the external air. That is, as described above, the circulation air is heat-exchanged 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 circulation air in the front heat exchanger 210 is higher in a temperature than the external air, the external air flowing along an outer side of the front heat exchanger 210 takes the heat of the circulation air in the front heat exchanger 210. Therefore, the temperature of the circulation air in the front heat exchanger 210 is lowered and thus the moisture contained in the circulation air is condensed and flows downward.
- the circulation air passing through the front heat exchanger 210 is, as indicated by ⁇ , introduced into the side heat exchanger 220. That is, the circulation 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 circulation air passes through the second heat exchanger 224 and then to the first exchange unit. At this point, the external air outside of the side heat exchanger 220 takes the heat from the circulation air and thus the moisture contained in the circulation air is condensed.
- the air passing through the side heat exchanger 220 is introduced into the inner heat exchanger 200.
- the circulation air discharged through the first outlet 222a of the first heat exchanger 222 is, as indicated by ⁇ , introduced into the barrier through the air inlet 146' formed through the barrier 130.
- the circulation air is, as indicated by ⁇ , introduced into the inner heat exchanger 200 through the air outlet 146 and the inner inlet 202.
- the circulation air introduced into the inner heat exchanger 200 is heat-exchanged with the external air. That is, after passing through the adsorption member 182, the circulation air is heat-exchanged with the air directed to a rear side of the barrier through the central through hole 134 of the barrier 130.
- the circulation air in the inner heat exchanger 200 is cooled and thus the moisture contained in the circulation air is condensed and discharged downward.
- the circulation air passing through the inner heat exchanger 200 is, as indicated by ⁇ , 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 circulation air in the inner heat exchanger 200 is introduced into the recovery assembly 160.
- the circulation air introduced into the recovery assembly 160 is forcedly directed by the recovery fan (not shown) into the heater assembly 170 through the recovery outlet 164 as indicated by ⁇ .
- the circulation air circulates along the closed flow path in which the heat exchangers 200, 210, and 220 are arranged, thereby completing one cycle.
- the condensed water generated by the heat exchange between the external air and the circulation air must be removed frequently by the user.
- the condensed water generated by the temperature difference in the heat exchangers 200, 210, and 220 falls down along the inner walls of the heat exchangers 200, 210, and 220 and is collected in the drain pan 250.
- the water guide members 206, 216, 222', 224', and 226' protruding downward are formed on the lower ends of the heat exchangers 200, 210, and 220 and communicate with the inside of the drain pan 250 by being inserted in the insertion holes 154, 156, and 158 of the drain pan receiving portion 152, the condensed water generated in the heat exchangers 200, 210, and 220 is collected in the drain pan 250 through the water guide members 206, 216, 222', 224', and 226'.
- the condensed water collected in the drain pan 250 falls into the water tank 300. That is, the condensed water that is temporarily collected in the drain pan 250 falls into the water tank 300 through a hole formed through a side of the drain pan 250.
- an amount of the moisture container in the air can be reduced by increasing a temperature of the external air passing through the heat exchangers and the moisture adsorbed in the adsorption member can be vaporized. Therefore, the industrial applicability of the present invention is very high.

Description
- The present invention relates to a dehumidifier. More particularly, the present invention relates to dehumidifier in which a flow path of air circulating along a plurality of heat exchangers is formed in a closed-circuit.
- Generally, 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.
- The dehumidifier of the related art uses only one heat exchanger to remove the moisture from the air and thus the dehumidifying efficiency is relatively low. Further, when the air passing through the single heat exchanger flows only in a direction from an inlet to an outlet, the dehumudifying reliability is deteriorated.
- Accordingly, there is a need for a dehumidifier that can improve the dehumidifying reliability and efficiency by forming a flow path of air circulating through a plurality of heat exchangers in a closed-circuit.
-
JP 2002/326012 - air passes through the heating means after taking heat contained in the adsorbent.
WO 2006/135171 also discloses a dehumidifier, using a desiccant assembly. - It would be desirable to provide a dehumidifier in which a flow path of air circulating along a plurality of heat exchangers is formed in a closed-circuit. It would also be desirable to provide a dehumidifier in which relatively high
- temperature circulation air passes through a moisture adsorption member containing moisture so that the moisture adsorbed in the moisture adsorption member can be vaporized, thereby making it possible to permanently use the moisture adsorption member.
- Accordingly, the invention provides a dehumidifier as set out in claim 1.
- According to the dehumidifier of the present invention, a circulation air path along which external air introduced from a lateral side is formed in a continues cycle in the heat exchangers contacting the introduced air and the circulation air is heated by the heater. Therefore, the circulation air in the heat exchangers maintains a relatively high temperature as compared with external air and thus a temperature of the external air passing through the heat exchangers increases, thereby reducing an amount of moisture contained in the air is reduced.
- Further, the circulation air circulating inside of the heat exchangers is heated by the heart and subsequently passes through the moisture adsorption member to vaporize the moisture adsorbed in the moisture adsorption member. As a result, the moisture adsorption member keeps removing the moisture from the external air. That is, the moisture adsorption member can be semi-permanently used.
- Furthermore, since the circulation air remove moisture from the external air and from the adsorption member without using a separate component, the structure of the dehumidifier can be simplified and the dehumidifying efficiency can be improved.

Fig. 8 is a schematic view of an external air flow state in the humidifier according to an embodiment of the present invention,Fig. 9 is a schematic view of an air flow state in rear of a barrier of the humidifier according to an embodiment of the present invention,Fig. 10 is a view illustrating an circulation air flow path inFig. 2 , andFig. 11 is a view illustrating a circulation air flow path inFig. 2 . - An operation of the above-described dehumidifier of the present invention will be described hereinafter with reference to
Figs. 8 through 11 . - Referring first to
Fig. 8 , external air is introduced into the dehumidifier through a side surface (right surface) of the dehumidifier. The air dehumidified in the dehumidifier is discharged to the external side (indoor space) through an upper end of the dehumidifier. That is, the dehumidified air is discharged through the gap between thetop panel 120 and other panels. - In more detail, when the
blower motor 240 is driven, theblower fan 246 rotates by the torque of theblower motor 240. - When the
adsorption motor 176 is driven, the adsorption assembly rotates 180 by the torque of theadsorption motor 176 and thus the recovery fan (not shown) provided in therecovery assembly 160 also rotates to generate a current of the circulation air. At this point, the torque generated by theadsorption motor 176 is lower than the torque generated by the recovery motor or theblower motor 240. Therefore, theadsorption assembly 180 rotates with a relatively low RPM. - At this same time, the heater (not shown) provided in the heater assembly is driven by the external power to heat the air.
- Meanwhile, as the
blower fan 246 rotates, sucking force is generated in the dehumidifier and thus the external air (air in the indoor space) is introduced into themain body case 110 through theair inlet 128 of the right panel 116 (see ① inFig. 8 ). - The external air introduced into the
main body case 110 passes through theside heat exchanger 220 as indicated by ② inFig. 8 . That is, the air passes successively through the air passing holes provided in the form of slits on the first, second, and thirdheat exchange units - At this point, the air outside of the
side heat exchanger 220 is heat-exchanged with the air inside of theside heat exchanger 220. Accordingly, a temperature of the air outside of theside heat exchanger 220 increases by the hot circulation air in theside heat exchanger 220. - The air passing through the
side heat exchanger 220 passes through thefront heat exchanger 210 as shown inFig. 8 . That is, the external air flows from the right and front sides of thefront heat exchanger 210 to the rear side of thefront heat exchanger 210. At this point, the airs inside and outside of thefront heat exchanger 210 are heat-exchanged with each other. - The air passing through the
front heat exchanger 210 passes through theadsorption member 182 as indicated by ④ inFig. 8 . Therefore, the moisture contained in the air is adsorbed in a surface of theadsorption member 182. Therefore, the air becomes more dry air. - The external air passing through the
adsorption assembly 180 passes through theinner heat exchanger 200 as indicated by ⑤ ofFig. 8 . Likewise, the airs inside and outside of theinner heat exchanger 200 are heat-exchanged with each other and thus a temperature of the air is further increased. - The air passing through the
inner heat exchanger 200 flows to the rear side of thebarrier 130 through the central throughhole 134 of thebarrier 130 as indicated by ⑥ ofFig. 8 . The air directed to the rear side of the barrier is discharged in a radial direction by theblower fan 246 and guide by theairflow guide 148. - The
airflow guide 148 encloses the outer side of theblower fan 246 and has a left end extending upward. Thus, the air discharged by theblower fan 246 flows toward the left upper portion of thebarrier 130 as indicated by ⑦ ofFig. 8 . - Describing the airflow state by the
airflow guide 148 in more detail with reference toFig. 9 , the air discharged in the circumferential direction by theblower fan 246 is guided by thecircular guide portion 148" and directed leftward (rightward inFig. 9 ) as indicated by (7a). - Subsequently, the air flows upward by the
upward guide portion 148", and as indicated by (7b), the air passes through the gap between the upper end of theupward guide portion 148" and theleft panel 118. - The air passing through the gap between the upper end of the
upward guide portion 148" and theleft panel 118 is partly directed to a front side of thebarrier 130 through the gap between the upper end of thebarrier 130 and thetop panel 120. That is, since the gap is formed between thetop panel 120 and the upper end of thebarrier 130, as indicated by (7c), the air in rear of thebarrier 130 flows toward the front side of thebarrier 130. - As described above, the air ascended by the
airflow guide 148 flows to the front side of thebarrier 130. At this point, the shieldingplate 230 in front of thebarrier 130 blocks the downward flow of the air so that the air guided upward by theairflow guide 148 cannot be introduced again into theadsorption assembly 180. That is, the air direction upward by theairflow guide 148 flows to the lower side of theshielding plate 230 so as not to be mixed with the air that is being introduced from the external side. - The air directed upward is dispersed toward the edge of the
top panel 120 and discharged through theair outlet 122. That is, as indicated by ⑧ ofFig. 8 , the air is discharged to the external side through theair outlet 122 defined by the gap between the top panel and themain body case 110. The method for discharging the air through theair outlet 122 defined by the gap provided in the form of slits is called a line diffuser method. - The flow of the circulation air in the
heat exchangers Figs. 10 and11 . - The circulation air path formed along the
heat exchangers heat exchangers - Describing in more detail, the circulation air directed from the
recovery assembly 160 is, as indicated by □, introduced into theheater assembly 170 through theheater inlet 174 connected to therecovery outlet 164. - The circulation air introduced into the
heater assembly 170 is heated by a heater (not shown) and directed frontward as indicated by □ through theheater outlet 172. The circulation air directed frontward through theheater outlet 172 passes through theadsorption member 182. At this point, the high temperature circulation air discharged through theheater outlet 172 vaporizes the moisture adsorbed in theadsorption member 182. - That is, as the
adsorption member 182 rotates with a low RPM by theadsorption motor 176, the moisture contained in the air passing through theadsorption member 182 is adsorbed in theadsorption member 182. At this point, as the high temperature circulation air passes through theadsorption member 182 as described above, the moisture adsorbed in theadsorption member 182 is vaporized and thus removed from theadsorption member 182. - In addition, since the
heater outlet 172 is formed in the fan-shape, theadsorption member 182 affected by the high temperature circulation air discharged through theheater outlet 172 becomes a range (fan-shape) corresponding to theheat outlet 172. However, since theadsorption member 182 keeps rotating with the low RPM by theadsorption motor 176, theadsorption member 182 entirely contacts the high temperature circulation air discharged through theheater outlet 172 when a predetermined time has elapsed. - The circulation air passing through the
adsorption member 182 is introduced into thehot air guide 192 of theadsorption frame 190 and subsequently directed into thefront heat exchanger 210 through thefront air inlet 212 of thefront heat exchanger 210 as indicated by □. - The circulation air directed into the
front heat exchanger 210 is heat-exchanged with the external air. That is, as described above, the circulation air is heat-exchanged with the external air which is introduced through theair inlet 128 and flows along an external side of thefront heat exchanger 210. - In more detail, since the circulation air in the
front heat exchanger 210 is higher in a temperature than the external air, the external air flowing along an outer side of thefront heat exchanger 210 takes the heat of the circulation air in thefront heat exchanger 210. Therefore, the temperature of the circulation air in thefront heat exchanger 210 is lowered and thus the moisture contained in the circulation air is condensed and flows downward. - The circulation air passing through the
front heat exchanger 210 is, as indicated by □, introduced into theside heat exchanger 220. That is, the circulation air in thefront heat exchanger 210 is directed to the thirdheat exchange unit 226 through thefront outlet 214 and subsequently introduced into thethird heat exchanger 226 through thethird inlet 226b. Subsequently, the circulation air passes through thesecond heat exchanger 224 and then to the first exchange unit. At this point, the external air outside of theside heat exchanger 220 takes the heat from the circulation air and thus the moisture contained in the circulation air is condensed. - The air passing through the
side heat exchanger 220 is introduced into theinner heat exchanger 200. In more detail, the circulation air discharged through thefirst outlet 222a of thefirst heat exchanger 222 is, as indicated by □, introduced into the barrier through the air inlet 146' formed through thebarrier 130. The circulation air is, as indicated by □, introduced into theinner heat exchanger 200 through theair outlet 146 and theinner inlet 202. - Like the side and
front heat exchangers inner heat exchanger 200 is heat-exchanged with the external air. That is, after passing through theadsorption member 182, the circulation air is heat-exchanged with the air directed to a rear side of the barrier through the central throughhole 134 of thebarrier 130. - Accordingly, the circulation air in the
inner heat exchanger 200 is cooled and thus the moisture contained in the circulation air is condensed and discharged downward. - The circulation air passing through the
inner heat exchanger 200 is, as indicated by □, introduced into therecovery assembly 160. That is, since theinner inlet 204 of theinner heat exchanger 200 is coupled to therecovery inlet 162 of therecovery assembly 160, the circulation air in theinner heat exchanger 200 is introduced into therecovery assembly 160. - The circulation air introduced into the
recovery assembly 160 is forcedly directed by the recovery fan (not shown) into theheater assembly 170 through therecovery outlet 164 as indicated by □. - Through the above-described process, the circulation air circulates along the closed flow path in which the
heat exchangers - The condensed water generated by the heat exchange between the external air and the circulation air must be removed frequently by the user.
- Describing the above-described process in more detail, the condensed water generated by the temperature difference in the
heat exchangers heat exchangers drain pan 250. That is, since thewater guide members heat exchangers drain pan 250 by being inserted in the insertion holes 154, 156, and 158 of the drainpan receiving portion 152, the condensed water generated in theheat exchangers drain pan 250 through thewater guide members - The condensed water collected in the
drain pan 250 falls into thewater tank 300. That is, the condensed water that is temporarily collected in thedrain pan 250 falls into thewater tank 300 through a hole formed through a side of thedrain pan 250. - When a certain amount of condensed water is collected in the
water tank 300 through the above-described process, the user takes the water tank out in a side direction and empties the water tank. - It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention. Thus, it is intended that the present invention covers the modifications and variations of this invention provided they come within the scope of the appended claims
- By using the above-described dehumidifier of the present invention, an amount of the moisture container in the air can be reduced by increasing a temperature of the external air passing through the heat exchangers and the moisture adsorbed in the adsorption member can be vaporized. Therefore, the industrial applicability of the present invention is very high.
