（実施の形態１）
図１は、本実施の形態１の除湿装置の外観図であり、図２は図１内のＡ−Ａ断面における概略を示す断面図である。

The heat absorber 9 cools and dehumidifies the air to be dehumidified. The radiator 7 and the heat absorber 9 are arranged to face each other. The radiator 7 is arranged on the front side of the main body case 1, and the heat absorber 9 is arranged on the rear side of the main body case 1.
図３は、熱交換器４の構成を示す概略図である。図２、３に示すように、熱交換器４は、伝熱板Ａ１１および伝熱板Ｂ１２を交互に積層することにより構成されており、それぞれの伝熱板には、積層した際に風路が構成できるようにリブ１３が設けられている。そして、鉛直方向に流れる第１熱交換風路１４と、水平に流れる第２熱交換風路１５とを構成し、この風路間でそれぞれの伝熱板を介して熱交換を行っている。熱交換器４は、伝熱板を積層した状態で下面が傾斜した立方体となり、放熱器７と吸熱器９との間で、吸熱器９から放熱器７への風路中に設けられている。 FIG. 3 is a schematic diagram showing the configuration of the heat exchanger 4. As shown in FIGS. 2 and 3, the heat exchanger 4 is configured by alternately stacking heat transfer plates A11 and B12, and each heat transfer plate has an air passage when stacked. The ribs 13 are provided so that the above can be configured. Then, a first heat exchange air passage 14 that flows in the vertical direction and a second heat exchange air passage 15 that horizontally flows are configured, and heat is exchanged between the air passages through the respective heat transfer plates. The heat exchanger 4 is a cube whose lower surface is inclined in a state in which heat transfer plates are stacked, and is provided between the radiator 7 and the heat absorber 9 in the air passage from the heat absorber 9 to the radiator 7. ..
送風機５は、スクロール形状のケーシング部１６と、このケーシング部１６に固定されたモータ部１７と、このモータ部１７によって回転する羽根部１８とから形成している。ケーシング部１６は、吸込口１９と吐出口２０とを備えている。この吸込口１９は、放熱器７に対向している。吸熱器９と、熱交換器４の第２熱交換風路１５と、放熱器７と、送風機５とは、水平方向に一直線上に配置されている。すなわち、吸熱器９と、熱交換器４と、放熱器７と、吸込口１９とは、一直線上に風路を有するものである。 The blower 5 includes a scroll-shaped casing portion 16, a motor portion 17 fixed to the casing portion 16, and a blade portion 18 rotated by the motor portion 17. The casing 16 includes a suction port 19 and a discharge port 20. The suction port 19 faces the radiator 7. The heat absorber 9, the second heat exchange air passage 15 of the heat exchanger 4, the radiator 7, and the blower 5 are arranged in a straight line in the horizontal direction. That is, the heat absorber 9, the heat exchanger 4, the radiator 7, and the suction port 19 have an air passage on a straight line.
送風機５によって、矢印に示すように、空気吸込口２からに吸気した空気は、熱交換器４の第１熱交換風路１４へ流入して、すでに吸熱器９により冷却除湿された空気と熱交換して予冷されたのち、吸熱器９における熱交換器４の底面より下方に突出した部分を通過し、その後風向を反転させ、さらに吸熱器９の残りの部分を通って冷却除湿される。なお、熱交換器４の底面より下方に突出した部分は通過せず、吸熱器９に一度のみ通過する風路もある。また、吸熱器９は、熱交換器４の底面から突出させず、吸熱器９の下端と熱交換器４の底面の上端とを同じ高さにしてもよい。 As shown by the arrow, the air taken in from the air suction port 2 by the blower 5 flows into the first heat exchange air passage 14 of the heat exchanger 4, and the air already cooled and dehumidified by the heat absorber 9 and the heat. After being exchanged and pre-cooled, the heat absorber 9 passes through a portion of the heat absorber 9 that protrudes downward from the bottom surface of the heat exchanger 4, then the wind direction is reversed, and the remaining portion of the heat absorber 9 is cooled and dehumidified. In addition, there is an air passage which does not pass through the portion projecting downward from the bottom surface of the heat exchanger 4 and passes through the heat absorber 9 only once. Further, the heat absorber 9 may not be projected from the bottom surface of the heat exchanger 4, and the lower end of the heat absorber 9 and the upper end of the bottom surface of the heat exchanger 4 may be at the same height.
冷却除湿された空気は熱交換器４の第２熱交換風路１５に流入し空気吸込口２から吸気した空気によって加熱され、放熱器７でさらに加熱され、送風機５によって機外に送風される。上記風路が、除湿を行う除湿経路２１となる。 The air that has been cooled and dehumidified is heated by the air that has flowed into the second heat exchange air passage 15 of the heat exchanger 4 and that has been taken in through the air suction port 2, is further heated by the radiator 7, and is blown outside by the blower 5. .. The air passage serves as a dehumidifying path 21 for dehumidifying.
熱交換器４および吸熱器９の下方には、水受け手段２２が設置されている。水受け手段２２には、熱交換器４の第１熱交換風路１４および吸熱器９に生成される結露水が滴下する。すなわち、空気吸込口２から流入した空気が熱交換器４にて予冷される段階で、第１熱交換風路１４内で水分が結露して水滴となって滴下することがあるが、熱交換器４の下方に除湿経路２１を兼ねた水受け手段２２を配置して結露水を受ける構造となっている。 Water receiving means 22 is installed below the heat exchanger 4 and the heat absorber 9. The dew condensation water generated in the first heat exchange air passage 14 of the heat exchanger 4 and the heat absorber 9 drops in the water receiving means 22. That is, when the air flowing in from the air suction port 2 is pre-cooled by the heat exchanger 4, water may condense in the first heat exchange air passage 14 and drop as water droplets. A water receiving means 22 which also serves as a dehumidifying path 21 is arranged below the vessel 4 to have a structure for receiving condensed water.
また、本体ケース１内の水受け手段２２の下部には、結露水を貯水するタンク２４を備え、水受け手段２２に設けた、たまった水滴をタンク２４に導出するドレン孔２５を通って、除湿水はタンク２４に回収される。 In addition, a tank 24 for storing condensed water is provided below the water receiving means 22 in the main body case 1, and passes through a drain hole 25 provided in the water receiving means 22 for discharging accumulated water droplets to the tank 24. The dehumidified water is collected in the tank 24.
また、吸熱器９の熱交換器４の反対側（本体ケース１の空気吸込口２側）で、水受け手段２２の上方には、吸熱器カバー２３を設ける。水受け手段２２と吸熱器カバー２３は、除湿経路２１における熱交換器４の第１熱交換風路１４から吸熱器９までの風路の一部である。 Further, a heat sink cover 23 is provided on the opposite side of the heat absorber 9 to the heat exchanger 4 (on the air suction port 2 side of the main body case 1) and above the water receiving means 22. The water receiving means 22 and the heat absorber cover 23 are a part of the air passage from the first heat exchange air passage 14 of the heat exchanger 4 to the heat absorber 9 in the dehumidification passage 21.
本実施形態における特徴は、
第１の除湿経路２１ａと、第２の除湿経路２１ｂと、を備えた構成としたことである。第１の除湿経路２１ａは、送風機５によって空気吸込口２から本体ケース１内に吸い込んだ空気を、熱交換器４の第１熱交換風路１４、吸熱器９、熱交換器４の第２熱交換風路１５、放熱器７、送風機５を介して前記空気吹出口から前記本体ケース外に吹き出す風路である。
第２の除湿経路２１ｂは、送風機５によって空気吸込口２から本体ケース１内に吸い込んだ空気を、熱交換器４の第１熱交換風路１４、熱交換器４の第２熱交換風路１５、放熱器７、送風機５を介して空気吹出口３から本体ケース１外に吹き出す風路である。
The feature of this embodiment is that
That is, the first dehumidification route 21a and the second dehumidification route 21b are provided. The first dehumidifying path 21 a is configured to transfer the air sucked into the main body case 1 from the air suction port 2 by the blower 5 to the first heat exchange air passage 14 of the heat exchanger 4, the heat absorber 9, and the second heat exchanger 4 of the heat exchanger 4. It is an air passage that blows out from the air outlet to the outside of the main body case via the heat exchange air passage 15, the radiator 7, and the blower 5.
The second dehumidification path 21b is a first heat exchange air passage 14 of the heat exchanger 4 and a second heat exchange air passage of the heat exchanger 4, in which air sucked into the body case 1 from the air suction port 2 by the blower 5 is used. This is an air passage that blows out from the air outlet 3 to the outside of the main body case 1 via the radiator 15, the radiator 7, and the blower 5.
なお、第１の除湿経路２１ａと第２の除湿経路２１ｂは、熱交換器４の第１熱交換風路１４までは、同一の経路であり、熱交換器４の第１熱交換風路１４通過後、それぞれの経路に分かれる。そして、第１の除湿経路２１ａは、吸熱器９および熱交換器４の第２熱交換風路１５を、第２の除湿経路２１ｂは、熱交換器４の第２熱交換風路１５を通過した後に、合流し、再び同一の経路となり、放熱器７、送風機５を介して空気吹出口３から本体ケース１外に吹き出す。つまり、第１の除湿経路２１ａは、吸熱器９と放熱器７の両方を通過する経路であるが、第２の除湿経路２１ｂは、吸熱器９を通過せず放熱器７を通過する経路である。これにより、放熱器７を通過する風量は、吸熱器９を通過する風量より大きくなる。 The first dehumidifying path 21a and the second dehumidifying path 21b are the same path up to the first heat exchange air passage 14 of the heat exchanger 4, and the first heat exchange air passage 14 of the heat exchanger 4 is the same. After passing, it is divided into each route. Then, the first dehumidifying path 21a passes through the second heat exchange air passage 15 of the heat absorber 9 and the heat exchanger 4, and the second dehumidifying path 21b passes through the second heat exchange air passage 15 of the heat exchanger 4. After that, they merge and form the same path again, and blow out from the air outlet 3 to the outside of the main body case 1 via the radiator 7 and the blower 5. That is, the first dehumidifying path 21a is a path that passes through both the heat absorber 9 and the radiator 7, but the second dehumidifying path 21b is a path that does not pass through the heat absorber 9 and passes through the radiator 7. is there. As a result, the air volume passing through the radiator 7 becomes larger than the air volume passing through the heat absorber 9.
冷凍サイクルと熱交換器とを用いる除湿装置の特徴として、除湿能力に対する消費電力が低いことが挙げられる。より消費電力を下げようとした場合に、放熱器７の風量を増加させることが考えられるが、第１の除湿経路２１ａと第２の除湿経路２１ｂとに分けなかった場合、放熱器７と吸熱器９の風量は等しくなるため、放熱器７の風量を増加させると、吸熱器９を通過する風速が早すぎるため、結露が十分に行われず、除湿能力が低下する場合があった。 One of the characteristics of the dehumidifying device that uses the refrigeration cycle and the heat exchanger is that the dehumidifying power consumption is low. When it is attempted to further reduce the power consumption, it is conceivable to increase the air volume of the radiator 7. However, if the first dehumidification path 21a and the second dehumidification path 21b are not divided, the radiator 7 and the heat absorption Since the air volume of the container 9 is equal, when the air volume of the radiator 7 is increased, the dew condensation ability may be deteriorated in some cases because dew condensation is not sufficiently performed because the wind speed passing through the heat absorber 9 is too fast.
このように、第１の除湿経路２１ａと第２の除湿経路２１ｂとに分けることにより、吸熱器９よりも放熱器７の風量を多くすることが可能になる。これにより、吸熱器９の風量を増加させることなく放熱器７の風量を増加させることができ、放熱器７の冷却を促進させることができるので、結果として、消費電力を低下させることができる。 By thus dividing the first dehumidifying path 21a and the second dehumidifying path 21b, it is possible to increase the air volume of the radiator 7 more than the heat absorber 9. As a result, the air volume of the radiator 7 can be increased without increasing the air volume of the heat absorber 9, and the cooling of the radiator 7 can be promoted. As a result, the power consumption can be reduced.
また、第２の除湿経路２１ｂにおける第２熱交換風路１５と熱交換する第１熱交換風路１４は、
第１の除湿経路２１ａにおける第２熱交換風路１５と熱交換する第１熱交換風路１４より、
第１熱交換風路１４を流れる空気における風上側の空気と熱交換する構成にしてもよい。
The first heat exchange air passage 14 that exchanges heat with the second heat exchange air passage 15 in the second dehumidification passage 21b is
From the first heat exchange air passage 14 that exchanges heat with the second heat exchange air passage 15 in the first dehumidification passage 21a,
You may make it the structure which exchanges heat with the air of the windward side in the air which flows through the 1st heat exchange air duct 14.
第１の除湿経路２１ａにおける第２熱交換風路１５に流入する空気は、第１熱交換風路１４、吸熱器９を順に通過し、十分に冷却された後に第２熱交換風路１５に流入するのに対し、第２の除湿経路２１ｂにおける第２熱交換風路１５に流入する空気は、第１熱交換風路１４を通過した後に第２熱交換風路１５に流入するため、第１の除湿経路２１ａよりも高い温度になる。 The air flowing into the second heat exchange air passage 15 in the first dehumidification passage 21a passes through the first heat exchange air passage 14 and the heat absorber 9 in order, and after being sufficiently cooled, enters the second heat exchange air passage 15. On the other hand, the air flowing into the second heat exchange air passage 15 in the second dehumidification passage 21b flows into the second heat exchange air passage 15 after passing through the first heat exchange air passage 14, so The temperature becomes higher than that of the first dehumidification path 21a.
一方、第１熱交換風路１４には、室内の空気が取り込まれる。第１熱交換風路１４における風上側が第２の除湿経路２１ｂにおける第２熱交換風路１５と熱交換することにより、予冷された状態で、第１熱交換風路１４の風下側を通過するため、第１熱交換風路１４では、より効率的に空気を冷却することができる。結果として、除湿性能を向上することができる。 On the other hand, indoor air is taken into the first heat exchange air passage 14. The windward side of the first heat exchange air passage 14 exchanges heat with the second heat exchange air passage 15 of the second dehumidification passage 21b to pass the leeward side of the first heat exchange air passage 14 in a pre-cooled state. Therefore, in the first heat exchange air passage 14, the air can be cooled more efficiently. As a result, the dehumidification performance can be improved.
また、吸熱器９と熱交換器４とは、水平方向に順に配置し、吸熱器９の上端部は、熱交換器４の上端部より下方に配置し、吸熱器９の上端部より上方の熱交換器４の第２熱交換風路１５が、第２の除湿経路２１ｂの一部となる構成にしてもよい。 Further, the heat absorber 9 and the heat exchanger 4 are arranged horizontally in order, and the upper end of the heat absorber 9 is arranged below the upper end of the heat exchanger 4 and above the upper end of the heat absorber 9. The second heat exchange air passage 15 of the heat exchanger 4 may be a part of the second dehumidification passage 21b.
すなわち、熱交換器４の第２熱交換風路１５において、吸熱器９の上端部より上方の風路は圧力損失が少なく、吸熱器９の上端部より下方の風路は圧力損失が高くなるため、熱交換器４の第２熱交換風路１５の下流にある放熱器７の、冷媒流れ方向上流における、比較的温度の高い領域に多く風を通過させることができる。結果として、消費電力を低下させることができる。 That is, in the second heat exchange air passage 15 of the heat exchanger 4, the air passage above the upper end of the heat absorber 9 has less pressure loss, and the air passage below the upper end of the heat absorber 9 has higher pressure loss. Therefore, a large amount of air can pass through a region of relatively high temperature upstream of the radiator 7 in the downstream of the second heat exchange air passage 15 of the heat exchanger 4 in the refrigerant flow direction. As a result, power consumption can be reduced.
また、吸熱器９の下端を、熱交換器４の第２熱交換風路１５における風上側面の下端より下方に配置し、吸熱器９を、熱交換器４の第２熱交換風路１５における風上側面の下端より下方に配置された第１の吸熱器部分２６と、熱交換器４の第２熱交換風路１５における風上側面の下端より上方に配置された第２の吸熱器部分２７と、を設け、送風機５によって空気吸込口２から本体ケース１内に吸い込んだ空気を、熱交換器４の第１熱交換風路１４、第１の吸熱器部分２６、第２の吸熱器部分２７、熱交換器４の第２熱交換風路１５、放熱器７、送風機５を介して空気吹出口３から本体ケース１外に吹き出す第３の除湿経路２１ｃを設ける構成としてもよい。 Further, the lower end of the heat absorber 9 is arranged below the lower end of the windward side surface of the second heat exchange air passage 15 of the heat exchanger 4, and the heat absorber 9 is arranged in the second heat exchange air passage 15 of the heat exchanger 4. First heat absorber portion 26 disposed below the lower end of the windward side surface of the heat exchanger 4, and a second heat absorber disposed above the lower end of the windward side surface of the second heat exchange air passage 15 of the heat exchanger 4. And a portion 27 is provided, and air sucked into the main body case 1 from the air suction port 2 by the blower 5 is used for the first heat exchange air passage 14 of the heat exchanger 4, the first heat absorber portion 26, and the second heat absorption. A third dehumidifying path 21c may be provided that blows out from the air outlet 3 to the outside of the main body case 1 via the vessel portion 27, the second heat exchange air passage 15 of the heat exchanger 4, the radiator 7, and the blower 5.
このように、吸熱器９を二度通過させることにより、より冷たい空気になり、熱交換器４の第２熱交換風路１５を通過する。すなわち、熱交換器４の第１熱交換風路１４の風下側をより冷却させることで、熱交換器４の第１熱交換風路１４出口空気をより冷却させることができる。結果として、除湿性能を向上させることができる。 Thus, by passing the heat absorber 9 twice, it becomes cooler air and passes through the second heat exchange air passage 15 of the heat exchanger 4. That is, by further cooling the leeward side of the first heat exchange air passage 14 of the heat exchanger 4, the outlet air of the first heat exchange air passage 14 of the heat exchanger 4 can be further cooled. As a result, the dehumidification performance can be improved.
本発明に係る除湿装置は、除湿性能の向上を可能とするものであるので、居室空間などで使用される除湿装置等として有用である。 INDUSTRIAL APPLICABILITY The dehumidifying device according to the present invention is capable of improving dehumidifying performance, and thus is useful as a dehumidifying device used in a living room space or the like.
