【発明の属する技術分野】
本発明は、空調機に係るもので、詳しくは、空調機から発生する凝縮水を除去し得る凝縮水除去装置及びその除去方法に関するものである。
【０００２】
【従来の技術】
一般に、空気調和機は、一定の空間を人間が活動するのに適当な温度・湿度及び気流の分布に調節すると共に空気中の埃などの異物質を除去する装置である。
且つ、空調機の動作中には、凝縮水が発生し、該空気から発生した凝縮水は、細菌の繁殖、黴の棲息及び腐敗によって悪臭が発生すると共に、前記空調機が動作される室内の空気が汚染される。
従って、空調機から発生する凝縮水を除去するために、パイプなどを利用して自然に排水を行うか又は、排水ポンプを利用して室内空調機の内部に流入される凝縮水を除去させる。
【０００３】
即ち、排水ポンプを利用して凝縮水を除去する場合、凝縮水の量が所定高さになると、自動的に排水ポンプが動作することで外部に凝縮水をポンピングするが、このとき、凝縮水レベルセンサが動作する高さ以下に溜まっている凝縮水は、常時室内空調機の内部に満ちているため、冷房停止時又は長期間空調機を使用しない場合、凝縮水に細菌の繁殖、黴の棲息及び腐敗によって空調機が汚染されると共に、空調機の撤去時に凝縮水が室内にあふれ出して室内のインテリアーを損傷させるという問題点がある。
【０００４】
そして、従来の空調機においては、図３に示したように、室内熱交換器３から吐出される低温及び低圧状態の冷媒ガスを高温及び高圧状態のガスに圧縮する圧縮機１と、該圧縮機１で圧縮された高温及び高圧状態の冷媒ガスが通過しながら周辺の水又は空気と熱を交換する室外熱交換器２と、該室外熱交換器２を通過した冷媒を低温及び低圧状態に変化させる膨脹装置４と、該膨脹装置４を通過した低温及び低圧の冷媒が通過しながら周辺の空気と熱を交換する室内熱交換器３と、暖房又は冷房の作動モードによって、前記冷媒の流動方向を調節する四方バルブ８と、定温除湿の時、高圧の冷媒をそのまま前記室内熱交換器３に流動させる二方バルブＢ１と、室内空気を吸入して前記室内熱交換器３の表面を通過させて外部に吐出する室内ファン７と、を包含して構成されていた。
【０００５】
又、前記室内熱交換器３は、定温除湿の時、高圧下で液体状と気体状とが混合された冷媒が通過しながら熱を放出させて高圧の液体状態の冷媒を吐出する第１熱交換器３ａと、該第１熱交換器３ａの高圧の液体状態の冷媒を低圧の液体状態に降下させる膨脹装置５と、該膨脹装置５を通って低圧下で液体状と気体状とが混合された冷媒を吸入して蒸発させることで、低温／低圧の気体状態の冷媒を吐出する第２熱交換器３ｂと、定温除湿の時、前記第１熱交換器３ａから吐出される高圧の液体状態の冷媒が直接第２熱交換器３ｂに吐出されることを遮断する二方バルブＢ２と、を包含して構成される。
【０００６】
又、前記空調機から発生する凝縮水を除去するための従来の凝縮水除去装置においては、図５に示したように、凝縮水貯蔵槽２３に貯溜される凝縮水の量を感知する凝縮水レベルセンサ２２と、前記凝縮水貯蔵槽２３に貯溜された凝縮水をパイプ２５を通して外部に排出する排水ポンプ２４と、前記凝縮水レベルセンサ２２で感知される凝縮水の量により前記排水ポンプ２４の駆動を制御する制御部２１と、を包含して構成されていた。
【０００７】
以下、このように構成された従来の空調機の動作に対して説明する。
先ず、暖房モードの場合、圧縮機１で高温高圧状態に圧縮された冷媒は、四方バルブ８を経て室内熱交換器３に流入されて凝縮された後、膨脹装置４を通過しながら低温低圧状態になる。
且つ、室内ファン７は、室内空気を吸入して前記室内熱交換器３の表面を通過させて再び外部に吐出させることで、室内空気は、前記室内熱交換器３と熱交換しながら室内の温度を上昇させ、前記室内熱交換器３は、第１熱交換器３ａと第２熱交換器３ｂ間の二方バルブＢ２を開放させて凝縮機として動作する。
【０００８】
次いで、前記室外熱交換器２は、低温低圧状態の冷媒を吸入してこれを蒸発させて気体状態に変化させ、前記圧縮機１は、前記室外熱交換器３から吐出される気体状態の冷媒を吸入して高温高圧の状態に圧縮するが、このような動作を反復遂行することで暖房運転が遂行される。
又、冷房モードの場合には、前記圧縮機１で高温高圧の状態に圧縮された冷媒は、四方バルブ８を経て前記室外熱交換器２に流入されて凝縮された後、前記膨脹装置４通過しながら低温低圧の状態になる。
【０００９】
次いで、前記室内熱交換器３は、前記低温低圧の状態の冷媒を吸入してこれを蒸発させて気体状態に変化させて吐出し、前記圧縮機１は、前記室内熱交換器３から吐出される気体状態の冷媒を吸入してこれを再び高温高圧の状態に圧縮する。
この時、前記室内熱交換器３は、前記第１熱交換器３ａと第２熱交換器３ｂ間の二方バルブＢ２を開放して蒸発器として動作し、前記室内ファン７は、室内空気を吸入して、前記室内熱交換器３の表面に通過させ、再び外部に吐出させることで、室内空気は、前記室内熱交換器３と熱交換しながら室内の温度を下降させる。
【００１０】
一方、定温除湿の場合、圧縮機１で高温高圧状態に圧縮された冷媒は、四方バルブ８を経て前記室外熱交換器２に流入されるが、この時、前記室外ファン６は、低回転数に回転するので、高温高圧の冷媒は殆ど冷却されない状態に、前記二方バルブＢ１を通過してそのまま前記室内熱交換器３に流入される。
次いで、前記室内熱交換器３は、内部の二方バルブＢ２を遮断して、前記第１熱交換器３ａと第２熱交換器３ｂとに分離して使用する。
【００１１】
即ち、前記第１熱交換器３ａは、高圧の液体状と気体状とが混合された冷媒を吸入して熱を放出させて高圧の液体状態に吐出し、前記第２熱交換器３ｂは、前記第１熱交換器３ａから吐出される高圧の液体状態の冷媒を前記膨脹装置５を通って低圧の液体状態に吸入してこれを蒸発させて低温低圧の気体状態の冷媒を吐出する。
この時、室内ファン７により吸入された室内空気が、前記第２熱交換器３ｂの冷却された表面を通過しながら熱交換されて湿気が除去された後、その湿気の除去された乾燥空気は第１熱交換器３ａの加熱された表面を通過しながら加熱されて室内に吐出される。
【００１２】
且つ、室内空気が空調機の前記室内熱交換器３と熱交換をする過程においては、図４に示したように、前記吸入部１１を通って前記本体１０に吸入された空気は、前記室内熱交換器３を通過しながら該室内熱交換器３の内部に流れる冷媒の蒸発潜熱により冷却され、前記室内熱交換器３で冷却された空気は、前記室内ファン７により上部に案内されて吐出部１２を通って室内に吐出されるが、該吐出部１２を通って吐出される空気は、上下風向ベーン１２ａ及び左右風向ベーン１２ｂの角度によって上下又は左右に風向が調節されながら室内の冷房を遂行する。図中、未説明符号１４は、室内吸入温度センサを示したものである。
【００１３】
【発明が解決しようとする課題】
然るに、このような従来の空調機においては、前記凝縮水レベルセンサ２２の動作する高さ以下に溜まっている凝縮水は、常時前記室内空調機２０の内部に貯溜されるようになるため、冷房停止時又は長期間空調機を使用しない場合は、該凝縮水に細菌の繁殖、黴の棲息及び腐敗によって室内空調機が汚染されると共に、空調機の撤去時に凝縮水が室内にあふれることで、室内のインテリアーを損傷させるという不都合な点があった。
【００１４】
本発明は、このような従来の課題に鑑みてなされたもので、空調機が設定時間以上停止されるか又は、強制冷房運転モードになるときは、凝縮水量の多少に拘りなく、それら凝縮水を外部に排出し得る空調機の凝縮水除去装置及びその除去方法を提供することを目的とする。
【００１５】
【課題を解決するための手段】
このような目的を達成するため、本発明に係る空調機の凝縮水除去装置においては、空調機の内部から発生した凝縮水を貯蔵する凝縮水貯蔵槽と、該凝縮水貯蔵槽に貯溜された凝縮水を外部に排出する排出部と、前記空調機の動作が停止されるとき、該停止された停止時間を測定する測定部と、前記停止時間が設定時間以上になると、排出部を動作させて凝縮水を外部に排出させる制御部と、を包含して構成されることを特徴とする。
【００１６】
又、本発明に係る空調機の凝縮水除去装置においては、空調機の内部から発生した凝縮水を貯蔵する凝縮水貯蔵槽と、該凝縮水貯蔵槽に貯溜された凝縮水を外部に排出する排出部と、前記空調機の動作が停止されるとき、該動作が停止された停止時間を測定する測定部と、前記凝縮水貯蔵槽に貯溜された凝縮水の量を測定する凝縮水の測定部と、前記停止時間が設定時間以上になると、排出部を動作させて凝縮水を外部に排出させ、前記空調機が動作する時には、凝縮水の測定部で測定された凝縮水の量が設定量以上の場合、凝縮水を外部に排出させる制御部と、を包含して構成されることを特徴とする。
【００１７】
又、本発明に係る空調機の凝縮水除去方法においては、空調機の動作が停止されると、該動作が停止した停止時間を測定する段階と、該停止時間が設定時間以上になると、前記空調機の凝縮水貯蔵槽に貯溜された凝縮水を外部に排出させる段階と、を順次行うことを特徴とする。
【００１８】
【発明の実施の形態】
以下、本発明の実施の形態に対し、図面を用いて説明する。
本発明に係る空調機の凝縮水除去装置においては、図１に示したように、空調機２００の内部から発生した凝縮水を貯蔵する凝縮水貯蔵槽２３０と、該凝縮水貯蔵槽２３０に貯溜された凝縮水を外部に排出する排出部２４０と、前記空調機の動作が停止されるとき、該動作が停止された停止時間を測定する測定部２５０と、該測定部２５０から測定された停止時間が設定時間以上になるとき、前記排出部２４０を制御して凝縮水を外部に排出させる制御部２１０と、を包含して構成されている。
【００１９】
又、前記凝縮水貯蔵槽２３０は、空調機の内部に装着されて空調機の動作中に室内熱交換器３００から発生する凝縮水を貯溜し、前記排出部２４０は、前記凝縮水貯蔵槽２３０の内部に装着されて制御部２１０の制御により前記凝縮水貯蔵槽２３０に貯溜された凝縮水を空調機の外部に排出させる。且つ、前記排出部２４０は、排水ポンプ２４１及び排水管２４２が前記凝縮水貯蔵槽２３０に連結されて該凝縮水貯蔵槽２３０に貯溜された凝縮水を制御部２１０の制御によって強制的に外部に排出させる。
【００２０】
又、前記測定部２５０は、空調機の停止時間を測定するために例えば、タイマーが前記制御部２１０に連結され、前記制御部２１０は、測定部２５０によって測定された停止時間と予め設定された設定時間とを比較して停止時間が設定時間より大きいときは、前記排出部２４０を動作させることで、前記凝縮水貯蔵槽２３０の凝縮水を空調機の外部に排出させる。
且つ、前記制御部２１０は、空調機の動作モードが冷房強制運転モード及び清掃モードの場合も、前記排出部２４０を動作させて前記凝縮水貯蔵槽２３０内の凝縮水を空調機の外部に排出させ、空調機が冷房運転を開始する時、及び停止する時も前記排出部２４０を動作させて前記凝縮水貯蔵槽２３０内の凝縮水を空調機の外部に排出させる。
【００２１】
以下、上記のように構成される本発明に係る空調機の凝縮水除去装置の動作に対して説明する。
空調機が動作を停止すると、前記測定部２５０によって停止時間が測定され、前記制御部２１０は、前記測定された停止時間と予め設定された設定時間とを比較し、停止時間が設定時間より大きいときに、前記排出部２４０を動作させる。
次いで、前記排出部２４０は、前記制御部２１０から入力された制御信号によって、前記排水ポンプ２４１が作動されることで、前記凝縮水貯蔵槽２３０の凝縮水が、前記排水管２４２を通って空調機の外部に排出される。
【００２２】
一方、前記空調機が動作する場合には、前記凝縮水の測定部２２０が凝縮水貯蔵槽２３０に貯溜された凝縮水の量を測定し、該測定された凝縮水の量は、前記制御部２１０によって予め設定された設定値と比較され、該比較結果、凝縮水の量が設定値以上の場合には、前記制御部２１０が排出部２４０を動作させて凝縮水を空調機の外部に排出させる。
又、前記制御部２１０は、空調機の動作モードの冷房強制モード又は清掃モードの与否を判断し、その動作モードが冷房強制モード又は清掃モードの場合には、前記排出部２４０を動作させる。
【００２３】
又、前記制御部２１０は、冷房運転の開始及び停止の与否を夫々判断し、空調機が冷房運転を開始及び停止する場合も、前記制御部２１０は、前記排出部２４０を作動させる。

BACKGROUND OF THE INVENTION
The present invention relates to an air conditioner, and more particularly to a condensate removal device that can remove condensed water generated from an air conditioner and a method for removing the same.
[0002]
[Prior art]
In general, an air conditioner is a device that adjusts a certain space to a temperature / humidity and airflow distribution suitable for human activity and removes foreign substances such as dust in the air.
Further, during the operation of the air conditioner, condensed water is generated, and the condensed water generated from the air generates a bad odor due to bacterial growth, habitat and spoilage, and the indoor air conditioner is operated. Air is contaminated.
Therefore, in order to remove the condensed water generated from the air conditioner, drainage is naturally performed using a pipe or the like, or condensed water flowing into the indoor air conditioner is removed using a drainage pump.
[0003]
That is, when removing condensed water using a drain pump, when the amount of condensed water reaches a predetermined height, the drain pump automatically operates to pump condensed water to the outside. Condensate collected below the height at which the level sensor operates is always filled inside the indoor air conditioner. Therefore, when cooling is stopped or when the air conditioner is not used for a long period of time, bacterial condensation and drought There is a problem that the air conditioner is polluted by sighs and decay, and condensate overflows into the room when the air conditioner is removed and damages the interior of the room.
[0004]
In the conventional air conditioner, as shown in FIG. 3, the compressor 1 compresses the low-temperature and low-pressure refrigerant gas discharged from the indoor heat exchanger 3 into the high-temperature and high-pressure gas, and the compression The outdoor heat exchanger 2 that exchanges heat with the surrounding water or air while the refrigerant gas compressed in the machine 1 passes through the high temperature and high pressure state, and the refrigerant that has passed through the outdoor heat exchanger 2 is brought into a low temperature and low pressure state. The expansion device 4 to be changed, the indoor heat exchanger 3 that exchanges heat with the surrounding air while the low-temperature and low-pressure refrigerant that has passed through the expansion device 4 passes, and the flow of the refrigerant according to the heating or cooling operation mode A four-way valve 8 for adjusting the direction, a two-way valve B1 for allowing high-pressure refrigerant to flow directly to the indoor heat exchanger 3 during constant temperature dehumidification, and sucking indoor air and passing through the surface of the indoor heat exchanger 3 Indoor fan that discharges outside And down 7 it was constituted encompass.
[0005]
The indoor heat exchanger 3 discharges heat and discharges a refrigerant in a high-pressure liquid state while a refrigerant in which a liquid and a gas are mixed under high pressure while the dehumidification is performed at a constant temperature. The exchanger 3a, the expansion device 5 for lowering the high-pressure liquid refrigerant of the first heat exchanger 3a to the low-pressure liquid state, and the liquid and gas are mixed under low pressure through the expansion device 5 The second heat exchanger 3b that discharges the low-temperature / low-pressure gaseous refrigerant by sucking the evaporated refrigerant and evaporating it, and the high-pressure liquid discharged from the first heat exchanger 3a during constant temperature dehumidification And a two-way valve B2 that blocks the refrigerant in the state from being discharged directly to the second heat exchanger 3b.
[0006]
Further, in the conventional condensed water removing apparatus for removing condensed water generated from the air conditioner, as shown in FIG. 5, the condensed water for sensing the amount of condensed water stored in the condensed water storage tank 23. A level sensor 22, a drain pump 24 that discharges condensed water stored in the condensed water storage tank 23 to the outside through a pipe 25, and the amount of condensed water detected by the condensed water level sensor 22 And a control unit 21 that controls driving.
[0007]
Hereinafter, the operation of the conventional air conditioner configured as described above will be described.
First, in the heating mode, the refrigerant compressed to a high temperature and high pressure state by the compressor 1 flows into the indoor heat exchanger 3 through the four-way valve 8 and is condensed, and then passes through the expansion device 4 to a low temperature and low pressure state. become.
The indoor fan 7 sucks indoor air, passes it through the surface of the indoor heat exchanger 3 and discharges it again to the outside, so that the indoor air is exchanged with the indoor heat exchanger 3 while exchanging heat with the indoor heat exchanger 3. The temperature is raised, and the indoor heat exchanger 3 operates as a condenser by opening the two-way valve B2 between the first heat exchanger 3a and the second heat exchanger 3b.
[0008]
Next, the outdoor heat exchanger 2 sucks low-temperature and low-pressure refrigerant and evaporates it to change to a gaseous state, and the compressor 1 is in a gaseous state discharged from the outdoor heat exchanger 3. Is compressed into a high temperature and high pressure state, and heating operation is performed by repeatedly performing such an operation.
In the cooling mode, the refrigerant compressed into a high temperature and high pressure state by the compressor 1 flows into the outdoor heat exchanger 2 through the four-way valve 8 and is condensed, and then passes through the expansion device 4. However, it becomes a low temperature and low pressure state.
[0009]
Next, the indoor heat exchanger 3 sucks the low-temperature and low-pressure refrigerant, evaporates it, changes it into a gaseous state, and discharges it. The compressor 1 is discharged from the indoor heat exchanger 3. The gaseous refrigerant is sucked and compressed again into a high temperature and high pressure state.
At this time, the indoor heat exchanger 3 operates as an evaporator by opening the two-way valve B2 between the first heat exchanger 3a and the second heat exchanger 3b, and the indoor fan 7 The air is sucked, passed through the surface of the indoor heat exchanger 3 and discharged to the outside again, so that the indoor air lowers the indoor temperature while exchanging heat with the indoor heat exchanger 3.
[0010]
On the other hand, in the case of constant temperature dehumidification, the refrigerant compressed to a high temperature and high pressure state by the compressor 1 flows into the outdoor heat exchanger 2 through the four-way valve 8, but at this time, the outdoor fan 6 has a low rotational speed. Therefore, the high-temperature and high-pressure refrigerant passes through the two-way valve B1 and flows into the indoor heat exchanger 3 without being cooled.
Next, the indoor heat exchanger 3 is used by separating the internal two-way valve B2 into the first heat exchanger 3a and the second heat exchanger 3b.
[0011]
That is, the first heat exchanger 3a sucks a refrigerant mixed with a high-pressure liquid and gas, releases heat, and discharges it into a high-pressure liquid state, and the second heat exchanger 3b The high-pressure liquid refrigerant discharged from the first heat exchanger 3a is sucked into the low-pressure liquid state through the expansion device 5 and evaporated to discharge the low-temperature low-pressure gaseous refrigerant.
At this time, after the indoor air sucked by the indoor fan 7 is subjected to heat exchange while passing through the cooled surface of the second heat exchanger 3b to remove the moisture, the dry air from which the moisture has been removed is It is heated while passing through the heated surface of the first heat exchanger 3a and discharged into the room.
[0012]
In the process of exchanging heat between the indoor air and the indoor heat exchanger 3 of the air conditioner, as shown in FIG. 4, the air sucked into the main body 10 through the suction portion 11 is The air cooled by the latent heat of vaporization of the refrigerant flowing inside the indoor heat exchanger 3 while passing through the heat exchanger 3, and the air cooled by the indoor heat exchanger 3 is guided and discharged upward by the indoor fan 7. Although air is discharged into the room through the section 12, the air discharged through the discharge section 12 cools the room while the air direction is adjusted up and down or left and right according to the angles of the up and down air direction vanes 12a and the left and right air direction vanes 12b. Carry out. In the figure, reference numeral 14 denotes an indoor intake temperature sensor.
[0013]
[Problems to be solved by the invention]
However, in such a conventional air conditioner, the condensed water accumulated below the height at which the condensed water level sensor 22 operates is always stored in the indoor air conditioner 20, so When the air conditioner is not used when stopped or for a long period of time, the condensed air is contaminated by the propagation of bacteria, habitat and spoilage, and the condensed water overflows into the room when the air conditioner is removed. There was a disadvantage of damaging the interior of the room.
[0014]
The present invention has been made in view of such a conventional problem. When the air conditioner is stopped for a set time or more, or when it enters the forced cooling operation mode, the condensed water amount is limited regardless of the amount of condensed water. An object of the present invention is to provide a condensate removal device for an air conditioner and a method for removing the same.
[0015]
[Means for Solving the Problems]
In order to achieve such an object, in the condensed water removing apparatus for an air conditioner according to the present invention, a condensed water storage tank for storing condensed water generated from the inside of the air conditioner, and the condensed water storage tank stored in the condensed water storage tank. When the operation of the air conditioner is stopped, the discharge unit that discharges condensed water to the outside, the measurement unit that measures the stopped stop time, and when the stop time exceeds the set time, the discharge unit is operated. And a controller that discharges condensed water to the outside.
[0016]
Moreover, in the condensed water removal apparatus for an air conditioner according to the present invention, a condensed water storage tank for storing condensed water generated from the inside of the air conditioner, and condensed water stored in the condensed water storage tank are discharged to the outside. When the operation of the air conditioner is stopped, the discharge unit, the measurement unit that measures the stop time when the operation is stopped, and the measurement of the condensed water that measures the amount of the condensed water stored in the condensed water storage tank And when the stop time is longer than the set time, the discharge unit is operated to discharge condensed water to the outside.
