Description

除濕裝置 Dehumidifier 發明領域 Field of invention

本發明是有關於一種利用冷凍循環進行冷卻除濕之除濕裝置。 The present invention relates to a dehumidifying device for cooling and dehumidifying by using a refrigeration cycle.

發明背景 Background of the invention

利用冷凍循環進行冷卻除濕之除濕裝置是揭示於例如日本特開2005-214533號公報。此種除濕裝置包含有：具有吸氣口與吹出口之本體外殼及設置於本體外殼內之冷凍循環裝置與熱交換部與送風機。 A dehumidifier for cooling and dehumidifying by a refrigeration cycle is disclosed in, for example, Japanese Patent Application Laid-Open No. 2005-214533. Such a dehumidification device includes a main body casing having an air inlet and an air outlet, and a refrigeration cycle device, a heat exchange unit, and a blower provided in the main body casing.

冷凍循環裝置是藉由壓縮機、依序設置於壓縮機之下游之散熱器、膨脹部及吸熱器而形成。熱交換部具有：進行熱交換之第一熱交換風路與第二熱交換風路。又，形成從吸氣口吸氣到本體外殼內之空氣的一部份藉由送風機而依序經由第一熱交換風路、吸熱器、第二熱交換風路及散熱器而往吹出口送風之除濕風路。 The refrigeration cycle device is formed by a compressor, a radiator, an expansion part, and a heat absorber which are sequentially arranged downstream of the compressor. The heat exchange unit includes a first heat exchange air path and a second heat exchange air path for heat exchange. In addition, a part of the air that is sucked from the suction port into the main body casing is blown by the blower to sequentially send air to the blow-out port through the first heat exchange air path, the heat absorber, the second heat exchange air path and the radiator. The dehumidification wind road.

發明概要 Summary of invention

然而，習知之除濕裝置中，在低溫季節時，有時候吸熱器在除濕時產生的水分會凍結，並在吸熱器之表面 產生霜。因此，具有當冷凍循環之運轉停止，僅藉由送風機之送風融解該霜時，則需要長時間的課題。 However, in the conventional dehumidification device, in the low temperature season, sometimes the water generated by the heat sink during dehumidification will freeze and be on the surface of the heat sink. Generates frost. Therefore, there is a problem that when the operation of the refrigeration cycle is stopped and the frost is melted only by the blower air, it takes a long time.

因此本發明之目的在於提高除濕裝置之除霜能力、縮短除霜時間。 Therefore, the purpose of the present invention is to improve the defrost ability of the dehumidifier and shorten the defrost time.

因此，本發明之除濕裝置包含有：具有吸氣口與吹出口與之本體外殼、設置於本體外殼內之熱泵裝置與熱交換部與送風機。熱泵裝置由壓縮機、散熱器、膨脹部及吸熱器所構成。熱交換部具有用以進行熱交換之第一熱交換風路與第二熱交換風路。又除濕裝置具有：從吸氣口經由第一熱交換風路、吸熱器、第二熱交換風路及散熱器到吹出口之除濕風路與從吸氣口經由吸熱器、第二熱交換風路及散熱器到吹出口之第1分流風路。藉由送風機而從吸氣口吸氣到本體外殼內之空氣分成除濕風路與第1分流風路。而且第1分流風路設有用以開關第1分流風路之開關部，並且控制部連接於開關部，控制部在除冰運轉時則停止壓縮機而使送風機運轉，並打開開關部。 Therefore, the dehumidifying device of the present invention includes a main body casing having an air inlet and an air outlet, a heat pump device, a heat exchange unit, and a blower provided in the main body casing. The heat pump device is composed of a compressor, a radiator, an expansion part, and a heat sink. The heat exchange section has a first heat exchange air path and a second heat exchange air path for heat exchange. The dehumidifier also includes a dehumidification air path from the air inlet through the first heat exchange air path, the heat absorber, the second heat exchange air path and the radiator to the air outlet, and from the air inlet through the heat absorber and the second heat exchange air. From the road and the radiator to the first outlet of the air outlet. The air sucked into the main body casing by the air blower by the blower is divided into a dehumidifying air path and a first diverting air path. In addition, the first branched air path is provided with a switch section for opening and closing the first branched air path, and the control section is connected to the switch section. During the deicing operation, the control section stops the compressor and causes the blower to operate, and opens the switch section.

如此之除濕裝置在除冰運轉時會打開第1分流風路之開關部，將從吸氣口吸氣到本體外殼內之空氣的一部份不通過第一熱交換風路而直接往吸熱器送風。其結果是，可增加空氣往吸熱器之風量並且送往吸熱器之空氣在第一熱交換風路不先預冷。因此，溫度高之空氣往吸熱器送風，而可有效地融解附著於吸熱器之霜，縮短除霜時間。 In this way, the dehumidification device will open the switch section of the first partial airflow path during the deicing operation, and a part of the air sucked from the air inlet to the body casing will not directly go to the heat absorber through the first heat exchange airflow path Supply air. As a result, the amount of air to the heat sink can be increased and the air sent to the heat sink is not pre-cooled in the first heat exchange air path. Therefore, high-temperature air is sent to the heat sink, which can effectively dissolve the frost attached to the heat sink and shorten the defrosting time.

熱泵裝置30由壓縮機2、散熱器3、作為膨脹部之毛細管4及吸熱器5所構成。而且，該等式依序由冷媒配管19連接，形成了冷凍循環。吸熱器5中，為除濕對象之空氣進行冷卻除濕。散熱器3與吸熱器5是對向配置。散熱器3位於靠近本體外殼1之背面側(另一側)，吸熱器5位於靠近本體外殼1之前面側(其中一側)。 The heat pump device 30 includes a compressor 2, a radiator 3, a capillary tube 4 as an expansion portion, and a heat absorber 5. The equations are sequentially connected by the refrigerant pipe 19 to form a refrigeration cycle. The heat absorber 5 cools and dehumidifies the air to be dehumidified. The heat sink 3 and the heat absorber 5 are opposed to each other. The heat sink 3 is located near the back side (the other side) of the main body case 1, and the heat sink 5 is located near the front side (one side) of the main body case 1.

熱交換部6的下面呈傾斜。熱交換部6設置於從吸熱器5往散熱器3之風路中。而且熱交換部6具有垂直方向之風路之第一熱交換風路8、水平方向之風路之第二熱交換風 路9。 The lower surface of the heat exchange section 6 is inclined. The heat exchange section 6 is provided in an air path from the heat absorber 5 to the radiator 3. In addition, the heat exchanging section 6 has a first heat exchanging air path 8 for a vertical air path, and a second heat exchanging air path for a horizontal air path. Road 9.

圖3是本發明之實施形態之除濕裝置之熱交換部的分解立體圖。如圖3所示，熱交換部6為例如直交流型之顯熱交換器、由樹脂或金屬等構成之第1傳熱板6a與第2傳熱板6b交互地積層而形成。 Fig. 3 is an exploded perspective view of a heat exchange section of the dehumidifier according to the embodiment of the present invention. As shown in FIG. 3, the heat exchange unit 6 is, for example, a direct-current type sensible heat exchanger, and a first heat transfer plate 6 a and a second heat transfer plate 6 b made of resin or metal are alternately laminated.

如圖2所示，送風機10由渦形之罩殼部14、固定於罩殼部14之馬達部15及藉由馬達部15旋轉之葉片部16形成。罩殼部14具有吸入口17與吐出口18。吸入口17與散熱器3對向。即吸熱器5、熱交換部6、散熱器3、吸入口17是配置於一直線上。 As shown in FIG. 2, the blower 10 is formed of a scroll-shaped casing portion 14, a motor portion 15 fixed to the casing portion 14, and a blade portion 16 rotated by the motor portion 15. The cover portion 14 includes a suction port 17 and a discharge port 18. The suction port 17 faces the radiator 3. That is, the heat absorber 5, the heat exchange part 6, the radiator 3, and the suction port 17 are arrange | positioned on a straight line.

藉由送風機10，如箭頭記號A、B所示，從吸氣口7吸入空氣。箭頭記號A之空氣往第一熱交換風路8之熱交換部6之上面的流入口8a流入，與已經被吸熱器5冷卻除濕之空氣進行熱交換而預冷，從熱交換部6之下面的流出口8b流出。接著，通過吸熱器5進行冷卻除濕。經冷卻除濕之空氣由第二熱交換風路9之熱交換部6之流入口9a再次進入交換部6，藉由從流入口8a流入之空氣被加熱，由流出口9b出去而在散熱器3進一步加熱，藉由送風機10送風到除濕裝置外。該路徑為除濕風路11。 As shown by arrow marks A and B by the blower 10, air is sucked from the air inlet 7. The air of the arrow A flows into the inflow port 8a above the heat exchange section 6 of the first heat exchange air path 8 and is pre-cooled by heat exchange with the air that has been cooled and dehumidified by the heat absorber 5, and from below the heat exchange section 6. The outflow port 8b flows out. Next, it is cooled and dehumidified by the heat absorber 5. The cooled and dehumidified air enters the exchange section 6 again through the inflow port 9a of the heat exchange section 6 of the second heat exchange air path 9, is heated by the air flowing in from the inflow port 8a, and exits through the outflow port 9b to the radiator 3. It is further heated and blown out of the dehumidifier by the blower 10. This path is a dehumidifying wind path 11.

本實施形態的特徴在於溶解附著於圖2之吸熱器5之霜的除冰運轉。該除冰運轉是送風機10在第1分流風路12之開關部21打開的狀態下運轉。具體而言，具有藉由送風機10，從吸氣口7吸入到本體外殼1內之空氣(箭頭記號A)的一部份依序經由吸熱器5、熱交換部6之第二熱交換風路9 及散熱器3而往吹出口13送風之第1分流風路12。 The feature of this embodiment is the deicing operation that dissolves the frost adhered to the heat sink 5 of FIG. 2. In this deicing operation, the blower 10 is operated in a state where the switch section 21 of the first branched air path 12 is opened. Specifically, a part of the air (arrow A) sucked into the housing 1 from the air inlet 7 by the blower 10 is sequentially passed through the second heat exchange air path of the heat absorber 5 and the heat exchange section 6 9 And the radiator 3 to the first branched air path 12 that sends air to the air outlet 13.

如此藉由送風機10從吸氣口7吸入到本體外殼1內之空氣分成除濕風路11與第1分流風路12。除濕風路11為從吸氣口7經過第一熱交換風路8、吸熱器5、第二熱交換風路9及散熱器3而到吹出口13之風路。又，第1分流風路12為從吸氣口7經過吸熱器5、第二熱交換風路9及散熱器3而到吹出口13之風路。 In this way, the air sucked into the main body casing 1 from the air inlet 7 by the blower 10 is divided into a dehumidifying air path 11 and a first diverting air path 12. The dehumidification air path 11 is an air path from the air inlet 7 through the first heat exchange air path 8, the heat absorber 5, the second heat exchange air path 9, and the radiator 3 to the air outlet 13. The first branched air path 12 is an air path from the air inlet 7 through the heat absorber 5, the second heat exchange air path 9, and the radiator 3 to the air outlet 13.

第1分流風路12設有用以開關第1分流風路12之開關部21。開關部21連接有控制部20。除冰運轉時，控制部20停止壓縮機2使送風機10運轉，並且打開第1分流風路12之開關部21。 The first diverting air path 12 is provided with a switch section 21 for opening and closing the first diverting air path 12. The switch section 21 is connected to a control section 20. During the de-icing operation, the control unit 20 stops the compressor 2 and operates the blower 10, and opens the switch unit 21 of the first split air path 12.

即控制部20在除冰運轉時打開第1分流風路12之開關部21，並從吸氣口7吸入到本體外殼1內之空氣(箭頭記號A)的一部份不通過熱交換部6之第一熱交換風路8而直接往吸熱器5送風。 That is, the control section 20 opens the switch section 21 of the first partial airflow path 12 during the deicing operation, and a part of the air (arrow mark A) sucked into the main body casing 1 from the air inlet 7 does not pass through the heat exchange section 6 The first heat exchange air path 8 sends air directly to the heat sink 5.

結果，增加往吸熱器5之風量。而且直接往吸熱器5送風之空氣在熱交換部6之第一熱交換風路8中不預冷，因此溫度高之空氣往吸熱器5送風。藉此附著於吸熱器5之霜可有效地融化。因此，除濕裝置之除霜能力變高，縮短除霜時間。 As a result, the air volume to the heat sink 5 is increased. In addition, the air directly sent to the heat absorber 5 is not pre-cooled in the first heat exchange air path 8 of the heat exchange section 6, so the air having a high temperature is sent to the heat absorber 5. As a result, the frost attached to the heat sink 5 can be effectively melted. Therefore, the defrost ability of the dehumidifying device becomes high, and the defrost time is shortened.

又，第1分流風路12之吸氣口7到開關部21之距離，比除濕風路11之吸氣口7到熱交換部6之第一熱交換風路8的距離短。即相較於除濕風路11，第1分流風路12的風阻較小。因此，第1分流風路12流入比除濕風路11多的空氣，有 效地融化吸熱器5之霜。 In addition, the distance between the air inlet 7 of the first split air path 12 and the switch section 21 is shorter than the distance between the air inlet 7 of the dehumidification air path 11 and the first heat exchange air path 8 of the heat exchange section 6. That is, compared with the dehumidification air path 11, the air resistance of the 1st divided air path 12 is small. Therefore, the first diverting air path 12 flows in more air than the dehumidifying air path 11, and Effectively melts the frost of heat sink 5.

又，當第1分流風路12之開關部21打開時，開關部21之至少一部份突出於除濕風路11中從吸氣口7到熱交換部6之第一熱交換風路8之間。 In addition, when the switch section 21 of the first shunt air path 12 is opened, at least a part of the switch section 21 protrudes from the first heat exchange air path 8 in the dehumidifying air path 11 from the air inlet 7 to the heat exchange section 6. between.

圖4是本發明之實施形態之除濕裝置之開關部的立體圖。如圖4所示，開關部21由開關板部24與旋動馬達部25所構成。 FIG. 4 is a perspective view of a switch unit of a dehumidifier according to the embodiment of the present invention. As shown in FIG. 4, the switch section 21 includes a switch plate section 24 and a rotation motor section 25.

如圖2所示，開關板部24設置於本體外殼1之前面側(其中一側)與吸熱器5之間，往上方凸形之曲面板。藉由旋動馬達部25，以開關板部24中之吸熱器5側為旋動中心，開關板部24中之本體外殼1之背面側(另一側)往俯仰方向旋動。開關板部24往仰角方向旋動時，開關部21會打開，開關板部24往俯角方向旋動時，開關部21會關閉。其中開關板部24往仰角方向旋動，當開關部21打開時，開關板部24之至少一部份突出於從除濕風路11中之吸氣口7到熱交換部6之第一熱交換風路8之間。 As shown in FIG. 2, the switch plate portion 24 is provided between the front side (one side) of the main body casing 1 and the heat sink 5, and is a curved panel convex upward. By rotating the motor portion 25 with the heat sink 5 side in the switch plate portion 24 as the rotation center, the rear side (the other side) of the main body casing 1 in the switch plate portion 24 is rotated in the pitch direction. When the switch plate portion 24 is rotated in the elevation direction, the switch portion 21 is opened, and when the switch plate portion 24 is rotated in the depression direction, the switch portion 21 is closed. The switch plate portion 24 is rotated in the elevation direction. When the switch portion 21 is opened, at least a part of the switch plate portion 24 protrudes from the first heat exchange from the air inlet 7 in the dehumidifying air path 11 to the heat exchange portion 6. Windy road between 8.

藉此，在除濕風路11流動之空氣(箭頭記號A)的一部份藉由開關部21之開關板部24導往第1分流風路12，增加在第1分流風路12流動之空氣。第1分流風路12會流入比除濕風路11多的空氣，因此吸熱器5之霜會更早融化。 Thereby, a part of the air (arrow mark A) flowing in the dehumidifying air path 11 is guided to the first branched air path 12 by the switch plate part 24 of the switch section 21, and the air flowing in the first branched air path 12 is increased. . The first diverting air path 12 will flow more air than the dehumidifying air path 11, so the frost of the heat sink 5 will melt earlier.

又，如圖2所示，在本體外殼1之前面側之其中一側上部設有吸氣口7。且在本體外殼1內之前面側之其中一側往背面側之另一側依序設有吸熱器5、熱交換部6、散熱器3及送風機10。散熱器3之散熱器上端部3a位於吸熱器5、 熱交換部6及閉狀態之開關部21之開關部上端部21a更上方。進而，散熱器3之散熱器上部3b與吸氣口7對向。 As shown in FIG. 2, an air inlet 7 is provided on an upper portion of one of the front side of the main body casing 1. A heat absorber 5, a heat exchange unit 6, a radiator 3, and a blower 10 are arranged in this order from one side of the front side to the other side of the back side in the main body housing 1. The upper end portion 3a of the radiator 3 is located at the heat sink 5, The upper end portion 21a of the switch portion of the heat exchange portion 6 and the switch portion 21 in the closed state is further above. Furthermore, the heat sink upper portion 3b of the heat sink 3 faces the air inlet 7.

藉此，藉由送風機10從吸氣口7吸入至本體外殼1內之空氣中，如箭頭記號B所示之空氣經由散熱器3而往吹出口13送風。此為第2分流風路22。即第2分流風路22是從吸氣口7不經過吸熱器5與第二熱交換風路9而經由散熱器3到吹出口13的風路。 Thereby, the air is sucked into the air in the main body casing 1 from the air inlet 7 by the blower 10, and the air as shown by the arrow B is sent to the air outlet 13 through the radiator 3. This is the second branched air path 22. That is, the second branched air path 22 is an air path from the air inlet 7 through the radiator 3 to the air outlet 13 without passing through the heat absorber 5 and the second heat exchange air path 9.

因此，藉由送風機10從吸氣口7吸入到本體外殼1內之空氣的一部份不經過熱交換部6(第一熱交換風路8及第2熱交換風路9)與吸熱器5而往散熱器3送風。也就是說從吸氣口7吸入到本體外殼1內之空氣分成通過除濕風路11之空氣(箭頭記號A)與通過第2分流風路22之空氣(箭頭記號B)。 Therefore, a part of the air sucked into the main body casing 1 through the air inlet 10 by the blower 10 does not pass through the heat exchange section 6 (the first heat exchange air path 8 and the second heat exchange air path 9) and the heat absorber 5 The air is supplied to the radiator 3. That is, the air sucked into the main body casing 1 from the air inlet 7 is divided into air passing through the dehumidifying air passage 11 (arrow mark A) and air passing through the second divided air passage 22 (arrow mark B).

其結果是，送風到熱交換部6與吸熱器5之空氣的除濕能力保持最適當的風量，並且增加送風到散熱器3之風量，因此防止除濕能力降低。又，第2分流風路22為風阻比除濕風路11少之風路，因此減輕送風機10之輸出增加。 As a result, the dehumidification capacity of the air sent to the heat exchange unit 6 and the heat absorber 5 maintains the optimum air volume, and the air volume sent to the radiator 3 is increased, thereby preventing the dehumidification capacity from being reduced. In addition, since the second shunt air passage 22 is an air passage having less wind resistance than the dehumidification air passage 11, the output of the blower 10 is reduced to increase.

又，如圖2所示，散熱器3之散熱器上端部3a位於吸熱器5、熱交換部6及關閉狀態之開關部21之開關部上端部21a更上方。散熱器3之散熱器上部3b與吸氣口7對向。第1分流風路12之開關部21打開時，開關部21之一部份突出至第2分流風路22中從吸氣口7到散熱器3之間。 As shown in FIG. 2, the heat sink upper end portion 3 a of the heat sink 3 is located further above the heat sink 5, the heat exchange portion 6, and the switch portion upper end portion 21 a of the switch portion 21 in the closed state. The heat sink upper portion 3b of the heat sink 3 faces the air inlet 7. When the switch section 21 of the first split air path 12 is opened, a part of the switch section 21 protrudes between the suction port 7 and the radiator 3 in the second split air path 22.

即，開關板部24往仰角方向旋動，開關部21打開時，開關板部24之至少一部份突出至第2分流風路22之從吸 氣口7到散熱器3之間的風路。藉此，流過第2分流風路22之空氣(箭頭記號B)也藉由開關板部24而導往第1分流風路12，增加在第1分流風路12流動的空氣。由於比除濕風路11多之空氣流入第1分流風路12，因此吸熱器5之霜會更快融化。 That is, when the switch plate portion 24 is rotated in the elevation direction, and when the switch portion 21 is opened, at least a part of the switch plate portion 24 protrudes to the second suction flow path 22 from the suction position. The air path between the air port 7 and the radiator 3. As a result, the air (arrow B) flowing through the second partial airflow path 22 is also guided to the first partial airflow path 12 by the switch plate portion 24, and the air flowing through the first partial airflow path 12 is increased. Since more air than the dehumidifying air path 11 flows into the first partial air path 12, the frost of the heat sink 5 will melt more quickly.

又，如圖2所示，除濕裝置具有用以測定吸熱器5之溫度的溫度測定部23。溫度測定部23之測定值比預定溫度高時，控制部20會進行壓縮機2與送風機10之運轉，並且進行關閉第1分流風路12之開關部21的除濕運轉。又，當溫度測定部23之測定值在預定溫度以下時，控制部20會停止壓縮機2，並且進行送風機10運轉，打開第1分流風路12之開關部21的除冰運轉。 As shown in FIG. 2, the dehumidifier includes a temperature measuring unit 23 for measuring the temperature of the heat absorber 5. When the measured value of the temperature measurement section 23 is higher than a predetermined temperature, the control section 20 performs the operation of the compressor 2 and the blower 10 and performs a dehumidification operation of the switch section 21 that closes the first branched air path 12. When the measured value of the temperature measurement unit 23 is lower than a predetermined temperature, the control unit 20 stops the compressor 2 and performs the operation of the blower 10 to open the deicing operation of the switch unit 21 of the first split air path 12.

圖5是本發明之實施形態之除濕裝置之控制部的流程圖。使用圖2與圖5說明除濕運轉與除冰運轉。 Fig. 5 is a flowchart of a control unit of the dehumidifier according to the embodiment of the present invention. The dehumidification operation and the deicing operation will be described with reference to FIGS. 2 and 5.

首先，當除濕裝置之除濕運轉開始時，藉由控制部20計測除濕運轉時間。該除濕運轉時間經過Ts時間(圖5之S1)時，控制部20藉由溫度測定部23測定吸熱器5之溫度，並比較該溫度測定值ts與預定溫度t0(圖5之S2)。 First, when the dehumidification operation of the dehumidifier starts, the control unit 20 measures the dehumidification operation time. The dehumidification operation time Ts elapsed time (Sl of FIG. 5), the control unit 20 by the temperature measuring section 23 measuring the temperature of the heat sink 5, and compares the measured temperature value t s and the predetermined temperature t 0 (of FIG. 5 S2) .

其中，控制部20是溫度測定值ts比預定溫度t0高時，則繼續除濕運轉並且也繼續吸熱器5之溫度測定。而且當比較溫度測定值ts與預定溫度t0(圖5之S2)，溫度測定部23之溫度測定值ts在預定溫度t0以下時，則進行控制部20使送風機10運轉並且停止壓縮機2，打開第1分流風路12之開關部21的除冰運轉(圖5之S3)。 Among them, when the temperature measurement value t s is higher than the predetermined temperature t 0 , the control unit 20 continues the dehumidification operation and also continues the temperature measurement of the heat sink 5. When the temperature measurement value ts is compared with the predetermined temperature t 0 (S2 in FIG. 5) and the temperature measurement value ts of the temperature measurement unit 23 is below the predetermined temperature t 0 , the control unit 20 operates the blower 10 and stops the compressor 2. Then, the deicing operation of the switch section 21 of the first diverting air path 12 is turned on (S3 in FIG. 5).

再者，預定溫度t0為在吸熱器5開始產生霜之溫度之負0.5℃加上0.5℃之範圍，亦可為0℃。即，當吸熱器5之溫度為開始產生霜之溫度時，則進行除冰運轉，因此霜會快速融化。 In addition, the predetermined temperature t 0 is in the range of minus 0.5 ° C. plus 0.5 ° C. from the temperature at which frost is generated at the heat sink 5, and may be 0 ° C. That is, when the temperature of the heat absorber 5 is the temperature at which frost starts to be generated, the de-icing operation is performed, so the frost will melt rapidly.

其次，控制部20將該除冰運轉之運轉時間進行積算。將積算時間Td與預定之除冰運轉時間T1進行比較(圖5之S4)。在此，若是積算時間Td比預定之除冰運轉時間T1短，控制部20則比較溫度測定值ts與預定溫度t0(圖5之S5)。而且，若溫度測定值ts比預定溫度t0低，則繼續除冰運轉並且再次比較積算時間Td與預定之除冰運轉時間T1(圖5之S4)。而且，當溫度測定值ts在預定溫度t0以上時，控制部20則結束除冰運轉(圖5之S6)，並且變更為除濕運轉。例如Ts=25分鐘、T1=10分鐘。 Next, the control unit 20 accumulates the operation time of the deicing operation. The operation time Td of the deicing operation and the predetermined time T 1 are compared (FIG. 5 of S4). Here, if the operation time Td shorter than a predetermined time of the deicing operation T 1, the control unit 20 comparing the measured value of the temperature ts and predetermined temperature t 0 (of FIG S5 5). If the temperature measurement value ts is lower than the predetermined temperature t 0 , the deicing operation is continued and the accumulated time Td is compared with the predetermined deicing operation time T 1 (S4 in FIG. 5). When the temperature measurement value ts is equal to or higher than the predetermined temperature t 0 , the control unit 20 ends the deicing operation (S6 in FIG. 5) and changes to the dehumidifying operation. For example, Ts = 25 minutes and T 1 = 10 minutes.

又，溫度測定部23設置於吸熱器5之吸熱器下部5a。即，除冰運轉時，吸熱器5之霜會從吸熱器5之上部融化，因此將溫度測定部23設置於吸熱器下部5a，藉此可確實地檢測到吸熱器5之霜已融化。 The temperature measurement unit 23 is provided on the heat sink lower portion 5 a of the heat sink 5. That is, during the deicing operation, the frost of the heat absorber 5 is melted from the upper part of the heat absorber 5. Therefore, by setting the temperature measuring section 23 on the heat absorber lower part 5 a, the frost of the heat absorber 5 can be reliably detected.

再者，本實施形態中，圖2中，從壓縮機2流出的冷媒從散熱器3之下方流入並且往上方流出。其次，冷媒經由毛細管4而從吸熱器5之上方流入而往下方流出，返回壓縮機2。也就是說，如圖2清楚所示，開關部21開放時，室內之暖空氣經由第1分流風路12吹往吸熱器5之最低溫的部分。藉此，有效地進行除霜。 In addition, in this embodiment, in FIG. 2, the refrigerant flowing out from the compressor 2 flows in from below the radiator 3 and flows upward. Next, the refrigerant flows in from above the heat sink 5 through the capillary 4 and flows out downward, and returns to the compressor 2. That is, as shown clearly in FIG. 2, when the switch section 21 is opened, the warm air in the room is blown to the lowest temperature portion of the heat sink 5 through the first branched air path 12. Thereby, defrosting is effectively performed.
