Description

本発明は、遠心送風機を有する除湿機に関する。より詳しくは、遠心ファンの構造を改善して送風性能を向上させた除湿機に関する。   The present invention relates to a dehumidifier having a centrifugal blower. More specifically, the present invention relates to a dehumidifier that improves the air blowing performance by improving the structure of a centrifugal fan.

除湿機は、冷媒の蒸発、凝縮過程で生じる熱の移動を用いて空気中の湿気を除去する装置である。除湿機は、室内空気を循環させるための送風ファンを有しており、特にこのような送風ファンとしてターボファンを用いて望む風量を吹き込んだ場合には、軸流ファンを使用する時に比べて騒音が低減する。   The dehumidifier is a device that removes moisture in the air using heat transfer generated in the process of evaporation and condensation of the refrigerant. The dehumidifier has a blower fan that circulates the room air. Especially when a desired air volume is blown by using a turbo fan as such a blower fan, the dehumidifier is noisier than when an axial fan is used. Is reduced.

図１に示す、ターボファンが適用された従来の除湿機は、前記除湿機の前面に吐出口１ｂが形成され、且つ、前記除湿機の後面に吸入口１ａが形成されたキャビネット１と、室内空気を強制流動させるためにキャビネット１の内部に設置されるターボファン３と、吸入口１ａとターボファン３との間に配置され、熱交換によって空気中の水分を除去する蒸発器４と、を備えている（例えば、特許文献１）。   A conventional dehumidifier to which a turbo fan is applied as shown in FIG. 1 includes a cabinet 1 in which a discharge port 1b is formed on the front surface of the dehumidifier and an intake port 1a is formed on the rear surface of the dehumidifier. A turbo fan 3 installed inside the cabinet 1 for forcibly flowing air, and an evaporator 4 disposed between the suction port 1a and the turbo fan 3 to remove moisture in the air by heat exchange. (For example, patent document 1).

図１に、このような除湿機における空気の流動方向を示す。ファンモーター２によってターボファン３が回転すると、室内空気が吸入口１ａから吸入され、室内空気中の水分は蒸発器４と凝縮器５を通って除去される。蒸発器４と凝縮器５とを通過した空気は、ターボファン３を経てターボファン３の半径方向に吐出される。
大韓民国特許出願公開第２００２−１２７６８号明細書 FIG. 1 shows the direction of air flow in such a dehumidifier. When the turbo fan 3 is rotated by the fan motor 2, room air is sucked from the suction port 1 a, and moisture in the room air is removed through the evaporator 4 and the condenser 5. The air that has passed through the evaporator 4 and the condenser 5 is discharged in the radial direction of the turbo fan 3 through the turbo fan 3.
Korean Patent Application Publication No. 2002-12768

しかしながら、従来の除湿機は、ターボファン３から半径方向へ吐出される空気が吐出口１ｂに自然に導かれず、キャビネット１の側面に衝突する構造となっているため、除湿機内に大きな送風抵抗が発生し送風効率が低下して、流動騒音が発生するという問題点があった。このような問題点は、製品の小型化のためにターボファン３の吐出側とキャビネット１間の空間を広く確保できない場合に、より深刻化する。   However, since the conventional dehumidifier has a structure in which the air discharged from the turbo fan 3 in the radial direction is not naturally guided to the discharge port 1b and collides with the side surface of the cabinet 1, a large blowing resistance is generated in the dehumidifier. There is a problem that the air blowing efficiency is reduced and the flow noise is generated. Such a problem becomes more serious when a large space between the discharge side of the turbofan 3 and the cabinet 1 cannot be secured due to the downsizing of the product.

本発明は、上記問題点を解決するためのものである。本発明の目的は、遠心送風機の構造を改善することによって、除湿機の送風性能を向上させ且つ騒音を低減することができる除湿機を提供することにある。   The present invention is to solve the above problems.

FIG. 3 is a side view showing the configuration of the dehumidifier according to one embodiment of the present invention. FIG. 4 is a perspective view showing a centrifugal fan in a dehumidifier according to an embodiment of the present invention.

図２及び図３に示すように、除湿機は、室内空気が吸入される吸入口１１及び室内空気が吐出される吐出口１２を有している本体１０と、吸入口１１から吸入される空気と熱交換して空気中の水分を除去できるように本体１０の内部に設置された熱交換器２０と、室内空気の循環のために熱交換器２０の後方に配置される遠心送風機１００と、除湿過程で生じる凝縮水を収集できるように熱交換器２０の下方に位置する水桶３０と、を備える。   As shown in FIGS. 2 and 3, the dehumidifier includes a main body 10 having a suction port 11 through which room air is sucked and a discharge port 12 through which room air is discharged, and air sucked from the suction port 11. A heat exchanger 20 installed inside the main body 10 so that moisture in the air can be removed by exchanging heat with the air, a centrifugal blower 100 disposed behind the heat exchanger 20 for circulation of indoor air, A water tank 30 positioned below the heat exchanger 20 so as to collect condensed water generated in the dehumidifying process.

吸入口１１は、本体１０の前面両側部にそれぞれ形成されている。吸入口１１の内側には、吸入される空気中に含まれている異物をろ過するフィルター１３が取り付けられている。吐出口１２は、本体１０の後面１０ａの両側部にそれぞれ配置され、本体１０の中心から側方（側面１０ｂ側）に離隔されるにつれて、本体１０の内側に向かって傾斜する傾斜吐出部１２ａと、傾斜吐出部１２ａに連結された状態で本体１０の側面１０ｂの一側に形成される側面吐出部１２ｂと、を備えて構成される。本体１０の後面１０ａの両側部に形成される吐出口１２を傾斜させて、本体１０の側面１０ｂの一側に吐出口１２を形成したのは、遠心送風機１００の送風特性を考慮したためである。すなわち、遠心送風機１００は、空気を送風機の半径方向、すなわち、本体１０の側面１０ｂに向かって吐出するという送風特性を考慮したためである。図２のように、後面１０ａに形成される吐出口１２ａが本体１０の内側に向かって傾斜するようにし、同時に側面１０ｂの一側にも吐出口１２ｂを形成すると、遠心送風機１００から吐出された空気が、送風抵抗を大きく受けることなく室内に円滑に排出され得る。   The suction ports 11 are respectively formed on both sides of the front surface of the main body 10. Inside the suction port 11, a filter 13 for filtering foreign matter contained in the sucked air is attached. The discharge ports 12 are respectively arranged on both side portions of the rear surface 10a of the main body 10, and are inclined discharge portions 12a that are inclined toward the inner side of the main body 10 as they are separated from the center of the main body 10 to the side (side surface 10b side). A side surface discharge portion 12b formed on one side of the side surface 10b of the main body 10 in a state of being connected to the inclined discharge portion 12a. The reason why the discharge ports 12 formed on both sides of the rear surface 10a of the main body 10 are inclined and the discharge ports 12 are formed on one side of the side surface 10b of the main body 10 is because the blowing characteristics of the centrifugal blower 100 are taken into consideration. That is, the centrifugal blower 100 takes into consideration the air blowing characteristics of discharging air toward the radial direction of the blower, that is, toward the side surface 10b of the main body 10. As shown in FIG. 2, when the discharge port 12a formed on the rear surface 10a is inclined toward the inside of the main body 10 and at the same time the discharge port 12b is formed on one side of the side surface 10b, the air is discharged from the centrifugal blower 100. The air can be smoothly discharged into the room without receiving a large blowing resistance.

一方、本体１０は、吐出口１２同士間において本体１０の後方へ突出する第１突出部１４を備えている。第１突出部１４は、本体１０が壁面に隣接して位置する場合に、吐出口１２と壁面間に一定の間隔を保たせることにより、吐出口１２が壁面によって塞がれることを防止する機能を担っている。同様に、吸入口１１同士間には、本体１０の前方へ突出する第２突出部１５が形成されている。   On the other hand, the main body 10 includes a first protrusion 14 that protrudes rearward of the main body 10 between the discharge ports 12. The first projecting portion 14 has a function of preventing the discharge port 12 from being blocked by the wall surface by keeping a certain distance between the discharge port 12 and the wall surface when the main body 10 is positioned adjacent to the wall surface. Is responsible. Similarly, a second projecting portion 15 that projects forward of the main body 10 is formed between the suction ports 11.

本体１０の内部空間は、中間隔板１６を介して前後方向に区画され、中間隔板１６の前方内部には熱交換器２０と水桶３０がそれぞれ配置され、中間隔板１６の後方内部には冷媒を高温・高圧に圧縮する圧縮機１７が配置される。中間隔板１６の上側には、空気が流動できるように送風口１６ａが形成され、この送風口１６ａには遠心送風機１００が装着される。   The internal space of the main body 10 is partitioned in the front-rear direction via the intermediate spacing plate 16, and the heat exchanger 20 and the water tank 30 are respectively arranged inside the front of the intermediate spacing plate 16. A compressor 17 that compresses the refrigerant to a high temperature and a high pressure is disposed. A blower port 16a is formed on the upper side of the intermediate spacing plate 16 so that air can flow, and the centrifugal blower 100 is attached to the blower port 16a.

熱交換器２０と水桶３０との間の一側には、排水口１８ａを持つドレインファン１８が設置される。ドレインファン１８は、熱交換器２０から落ちる凝縮水を収集して、その下部に配置された水桶３０に排出する。   On one side between the heat exchanger 20 and the water tank 30, a drain fan 18 having a drain port 18a is installed. The drain fan 18 collects the condensed water falling from the heat exchanger 20 and discharges it to the water tank 30 disposed below the drain fan 18.

熱交換器２０は、吸入口１１の後方に配置されて、吸入口１１から吸入される室内空気中の熱を吸収すると同時に、水分を凝結させる蒸発器２１と、蒸発器２１の後方に配置されて蒸発器２１を通過した空気に熱を提供する凝縮器２２とにより構成されている。   The heat exchanger 20 is disposed behind the suction port 11, absorbs heat in the room air sucked from the suction port 11, and at the same time, condenses moisture, and is disposed behind the evaporator 21. And a condenser 22 that provides heat to the air that has passed through the evaporator 21.

遠心送風機１００は、モーターマウント１９を介して中間隔板１６に固定されるファンモーター２００と、ファンモーター２００によって回転されて空気の流動を引き起こす遠心ファン３００とを備える状態で構成されている。   The centrifugal blower 100 is configured to include a fan motor 200 that is fixed to the intermediate spacing plate 16 via a motor mount 19 and a centrifugal fan 300 that is rotated by the fan motor 200 to cause air flow.

図３及び図４に示すように、遠心ファン３００は、ファンモーター２００に結合され回転するファンディスク３１０と、ファンディスク３１０の前面外周部に設置される複数のブレード３２０と、ブレード３２０の前端部に設置され、その中央に空気の吸入のための開口３３１が形成されたシュラウド３３０とを有する。このような遠心ファン３００がファンモーター２００によって回転すると、シュラウド３３０の開口３３１を介して軸方向に空気が吸入され、半径方向に空気が吐出される。   As shown in FIGS. 3 and 4, the centrifugal fan 300 includes a fan disk 310 that is coupled to the fan motor 200 and rotates, a plurality of blades 320 installed on the outer periphery of the front surface of the fan disk 310, and a front end portion of the blade 320. And a shroud 330 having an opening 331 for inhaling air at the center thereof. When such a centrifugal fan 300 is rotated by the fan motor 200, air is sucked in the axial direction through the opening 331 of the shroud 330, and air is discharged in the radial direction.

特に、本発明に係るファンディスク３１０は、吐出口１２に向かって傾斜する傾斜部３１１を有する。このような傾斜部３１１は、遠心ファン３００を通過する空気の流動を吐出口１２側に自然に導き、遠心ファン３００から吐出される空気が大きい抵抗を受けることなく本体１０から円滑に排出されるようにする。   In particular, the fan disk 310 according to the present invention has an inclined portion 311 that is inclined toward the discharge port 12. Such an inclined portion 311 naturally guides the flow of air passing through the centrifugal fan 300 to the discharge port 12 side, and the air discharged from the centrifugal fan 300 is smoothly discharged from the main body 10 without receiving a large resistance. Like that.

さらには、ファンディスク３１０は、ファンモーター２００との結合のためのモーター装着部３１２を有している。このモーター装着部３１２から半径方向にファンディスク３１０の傾斜部３１１が延在している。この場合においては、ブレード３２０は傾斜部３１１の外周に沿って配列される。一方、ファンモーター２００は、シュラウド３３０の開口３３１を介してファンディスク３１０のモーター装着部３１２に装着される。   Furthermore, the fan disk 310 has a motor mounting portion 312 for coupling with the fan motor 200. An inclined portion 311 of the fan disk 310 extends from the motor mounting portion 312 in the radial direction. In this case, the blades 320 are arranged along the outer periphery of the inclined portion 311. On the other hand, the fan motor 200 is mounted on the motor mounting portion 312 of the fan disk 310 through the opening 331 of the shroud 330.

傾斜部３１１は、モーター装着部３１２から送風ファン３００の後方に緩やかに傾斜されている第１傾斜部３１１ａと、第１傾斜部３１１ａから吐出口１２側へ折り曲げられた状態で所定長さで延在している第２傾斜部３１１ｂとから構成されている。第２傾斜部３１１ｂによって、第１傾斜部３１１ａを通過する空気は、遠心ファン３００から吐出される際に、吐出口１２に向かって拡散された状態で流動する。   The inclined portion 311 extends for a predetermined length in a state where the first inclined portion 311a is gently inclined from the motor mounting portion 312 to the rear of the blower fan 300 and is bent from the first inclined portion 311a to the discharge port 12 side. The second inclined portion 311b is present. When the second inclined portion 311b discharges the air passing through the first inclined portion 311a from the centrifugal fan 300, the air flows while being diffused toward the discharge port 12.

以下、図３及び図５を参照して、本発明における除湿機の動作について説明する。図５は、本発明による除湿機の動作説明図である。   Hereinafter, the operation of the dehumidifier according to the present invention will be described with reference to FIGS. 3 and 5. FIG. 5 is an explanatory diagram of the operation of the dehumidifier according to the present invention.

除湿機の動作が開始されると、ファンモーター２００によって遠心ファン３００が回転した状態となり、吸入口１１から室内空気が吸入される。この室内空気は、蒸発器２１を通過する際に蒸発器２１と熱交換して冷却され、空気中の水分は凝縮され蒸発器２１の下部に配置されたドレインファン１８に収集される。その後、蒸発器２１を通過した空気は、凝縮器２２を通過する際に熱が供給され、シュラウド３３０の開口３３１から遠心ファン３００の内部に吸入される。   When the operation of the dehumidifier is started, the centrifugal fan 300 is rotated by the fan motor 200 and the room air is sucked from the suction port 11. When this room air passes through the evaporator 21, it is cooled by exchanging heat with the evaporator 21, and moisture in the air is condensed and collected by the drain fan 18 disposed below the evaporator 21. Thereafter, the air that has passed through the evaporator 21 is supplied with heat when passing through the condenser 22, and is sucked into the centrifugal fan 300 from the opening 331 of the shroud 330.

遠心ファン３００の内部に流入した空気は、ファンディスク３１０の傾斜部３１１によって導かれて、本体１０に形成された吐出口１２側に向かって流動する。従って、遠心ファン３００から吐出された空気は、大きな抵抗を受けずに吐出口１２から排出され、その結果、送風効率が向上し且つ騒音が低減することになる。   The air that flows into the centrifugal fan 300 is guided by the inclined portion 311 of the fan disk 310 and flows toward the discharge port 12 formed in the main body 10. Therefore, the air discharged from the centrifugal fan 300 is discharged from the discharge port 12 without receiving a large resistance, and as a result, the blowing efficiency is improved and noise is reduced.

一方、ドレインファン１８に収集された凝縮水は、排水口１８ａから水桶３０に排出されて水桶３０に貯蔵される。   On the other hand, the condensed water collected by the drain fan 18 is discharged from the drain port 18 a to the water tank 30 and stored in the water tank 30.
