Description

本発明は、暖房機能を有する衣類乾燥機に関する。 The present invention relates to a clothes dryer having a heating function.

衣類乾燥機は、衣類乾燥室として設けられた回転ドラムの内部に、洗濯後の衣類（所謂洗濯物であってタオルやシーツ等の布製品を含む）を収容し、回転ドラムを回転させつつ内部に温風を通過させて衣類を乾燥させる。このとき、回転ドラムの内部の衣類から生じる湿気は、排湿ファンにより回転ドラム内部から強制的に排出される。 A clothes dryer stores clothes after washing (so-called laundry, including cloth products such as towels and sheets) inside a rotating drum provided as a clothes drying chamber, and rotates the rotating drum to dry the clothes inside. Dry the clothes by passing warm air through the At this time, moisture generated from the clothes inside the rotary drum is forcibly discharged from the inside of the rotary drum by the moisture exhaust fan.

ところで、この種の衣類乾燥機において、当該衣類乾燥機が設置されている脱衣室等を暖房することができる暖房機能を備えるものが提案されている（下記特許文献１参照）。この衣類乾燥機は、衣類乾燥機内で加熱した空気を排湿ダクトを介して室内に放出させることができ、これによって当該室内を暖房することが可能となっている。 By the way, in this type of clothes dryer, there has been proposed one having a heating function capable of heating a dressing room or the like in which the clothes dryer is installed (see Patent Document 1 below). This clothes dryer can discharge the air heated in the clothes dryer into the room through the moisture exhaust duct, thereby heating the room.

特開２０００－２５７８９４号公報JP-A-2000-257894

上記従来の衣類乾燥機の構成では、暖房用空気は回転ドラム内部を通って排出されるが、暖房運転中に回転ドラム内に衣類を収容した衣類乾燥運転を行うと、衣類から生じた湿気が室内に放出され、室内の湿度が過剰に上昇してしまう不都合があるため、暖房機能を使用する時には、衣類の乾燥を行えないようにしている。 In the configuration of the conventional clothes dryer described above, the heating air is discharged through the inside of the rotating drum. It is not possible to dry the clothes when the heating function is used because it is discharged into the room and the indoor humidity rises excessively.

しかし、暖房運転中に衣類乾燥運転を行うことができないために使い勝手が悪い。 However, it is inconvenient because the clothes drying operation cannot be performed during the heating operation.

上記の点に鑑み、本発明は、衣類乾燥運転と暖房運転とを同時に行うことができる衣類乾燥機を提供することを目的とする。 SUMMARY OF THE INVENTION In view of the above points, an object of the present invention is to provide a clothes dryer capable of simultaneously performing a clothes drying operation and a heating operation.

かかる目的を達成するために、本発明は、衣類を収容する衣類乾燥室と、該衣類乾燥室内に供給する空気を加熱する衣類乾燥用熱交換器と、該衣類乾燥用熱交換器に熱媒を供給する熱媒供給管と、前記衣類乾燥用熱交換器により加熱された空気を前記衣類乾燥室内に流動させると共に前記衣類乾燥室内の湿気を強制的に排出させる衣類乾燥用ファン装置とを筐体の内部に備える衣類乾燥機において、
前記熱媒供給管から分岐して延びる暖房用熱媒管と、該暖房用熱媒管から熱媒が供給される暖房用熱交換器と、該暖房用熱交換器により加熱された空気を強制的に送出する暖房用ファン装置とを前記衣類乾燥室と隔離させて前記筐体の内部に備え、前記筐体には、底面の下方に空隙を形成する脚部が設けられ、前記筐体の底面には、前記衣類乾燥用熱交換器によって加熱される空気を取り入れる乾燥用空気取り入れ口と、前記暖房用熱交換器によって加熱される空気を取り入れる暖房用空気取り入れ口とが形成され、前記両取り入れ口を共に覆うフィルタ部材が着脱自在に設けられており、前記筐体の底面には、前記暖房用熱交換器により加熱された空気の吹き出し口が形成されており、前記フィルタ部材は、前記吹き出し口に対応する位置に、前記吹き出し口から吹き出す暖房用空気を前方の斜め下方に案内する案内部を備えていることを特徴とする。 In order to achieve such an object, the present invention provides a clothes drying chamber for storing clothes, a clothes drying heat exchanger for heating air supplied to the clothes drying chamber, and a heat medium for the clothes drying heat exchanger. and a clothes-drying fan device for causing the air heated by the clothes-drying heat exchanger to flow into the clothes-drying chamber and forcibly discharging the moisture in the clothes-drying chamber. In the clothes dryer provided inside the body,
A heating heat medium pipe branched from the heat medium supply pipe, a heating heat exchanger to which the heat medium is supplied from the heating heat medium pipe, and forced air heated by the heating heat exchanger a fan device for heating and a fan device for heating are separated from the clothes drying chamber and provided inside the housing, and the housing is provided with a leg forming a gap below the bottom surface of the housing; A drying air intake for taking in air heated by the clothes drying heat exchanger and a heating air intake for taking in air heated by the heating heat exchanger are formed on the bottom surface of the A filter member that covers both intake ports is detachably provided, and a bottom surface of the housing is formed with an outlet port for air heated by the heating heat exchanger, and the filter member includes: A guide portion is provided at a position corresponding to the air outlet for guiding the heating air blown from the air outlet obliquely downward and forward .

上記構成によれば、衣類乾燥運転を行うとき、衣類乾燥用熱交換器により加熱した乾燥用空気を衣類乾燥用ファン装置によって衣類乾燥室内に送り込む。一方、暖房運転を行うときには、暖房用熱交換器により加熱した暖房用空気を暖房用ファン装置によって衣類乾燥室を通らずに送出する。従って、本発明によれば、衣類乾燥運転と暖房運転とを同時に行うことができる。しかも、暖房用熱交換器には、衣類乾燥用熱交換器に熱媒を供給する熱媒供給管から分岐する暖房用熱媒管が接続されているので、熱媒供給管にのみ熱媒を供給する配管施工を行うだけでよく、配管にかかる工事費用を抑えることができる。 According to the above configuration, when the clothes drying operation is performed, the drying air heated by the clothes drying heat exchanger is sent into the clothes drying chamber by the clothes drying fan device. On the other hand, when performing the heating operation, the heating air heated by the heating heat exchanger is sent out by the heating fan device without passing through the clothes drying chamber. Therefore, according to the present invention, the clothes drying operation and the heating operation can be performed simultaneously. Moreover, since the heating heat exchanger is connected to the heating heat medium pipe branching from the heat medium supply pipe that supplies the heat medium to the clothes drying heat exchanger, the heat medium is supplied only to the heat medium supply pipe. It suffices to install the pipes for supplying, and the construction cost for the pipes can be suppressed.

本発明によれば、乾燥用空気取り入れ口と暖房用空気取り入れ口とを筐体の底面に形成したことにより、フィルタ部材で両取り入れ口を同時に覆うができ、構造簡単として製造コスト等を抑えることができる。なお、筐体の底面の下方には脚部によって空隙が形成されているので、筐体外部から両取り入れ口への空気の流れが円滑に行われ、乾燥用空気及び暖房用空気の生成を効率よく行うことができる。 According to the present invention, by forming the drying air intake and the heating air intake on the bottom surface of the housing, it is possible to cover both intakes with the filter member at the same time, simplifying the structure and reducing manufacturing costs. can be done. In addition, since a gap is formed by the legs below the bottom surface of the housing, air flows smoothly from the outside of the housing to both intakes, and the drying air and heating air are efficiently generated. can do well.

ところで、例えば、暖房用空気を天井から下方に吹出すことにより室内の暖房を行うと、暖房用空気が床面近傍に到達し難く、暖房効率が悪い。 By the way, for example, if the room is heated by blowing the heating air downward from the ceiling, the heating air is difficult to reach the vicinity of the floor surface, resulting in poor heating efficiency.

これに対して、本発明は、筐体の底面に暖房用空気の吹き出し口を形成し、更に、案内部によって暖房用空気を前方の斜め下方に案内する。これにより、暖房用空気を天井から下方に吹出す場合に比べて、暖房用空気が床面近傍に到達し易く、暖房効率を向上させることができる。 On the other hand, according to the present invention, the heating air outlet is formed in the bottom surface of the housing, and the heating air is guided obliquely forward and downward by the guide section. As a result, compared to the case where the heating air is blown downward from the ceiling, the heating air can reach the vicinity of the floor more easily, and the heating efficiency can be improved.

また、例えば、筐体を設置台上に設置するとき、筐体の底面に暖房用空気の吹き出し口が形成されていると、暖房用空気の流れは設置台の上面に向くため暖房用空気の室内拡散が阻害されるおそれがある。 In addition, for example, when the housing is installed on the installation table, if the heating air outlet is formed in the bottom surface of the housing, the flow of the heating air is directed toward the upper surface of the installation table. Indoor diffusion may be hindered.

これに対して、本発明は、案内部が吹き出し口から吹き出す暖房用空気を前方の斜め下方に案内するので、設置台の上面に向く暖房用空気の流れを抑制することができ、暖房効率の低下を防止することができる。 On the other hand, in the present invention, since the guide section guides the heating air blown out from the outlet to the front and obliquely downward, it is possible to suppress the flow of the heating air directed toward the upper surface of the installation table, thereby improving the heating efficiency. A decrease can be prevented.

本発明の実施形態を図面に基づいて説明する。本実施形態の衣類乾燥機１は、図１に示す筐体２を備えている。筐体２には、底部の四隅部に取り付けられた脚部材３(脚部)と、底部を覆うフィルタ部材４とが設けられている。また、筐体２の前面には、円形で片開き式の扉５と、複数の操作スイッチ群や表示器等を備える操作パネル部６とが設けられている。 An embodiment of the present invention will be described based on the drawings. A clothes dryer 1 of this embodiment includes a housing 2 shown in FIG. The housing 2 is provided with leg members 3 (legs) attached to the four corners of the bottom and a filter member 4 covering the bottom. Further, on the front surface of the housing 2, there are provided a circular, single-open door 5, and an operation panel section 6 having a plurality of operation switches, displays, and the like.

次に、衣類乾燥機１の概略構成を説明する。図２に示すように、筐体２の内部には、回転ドラム７が設けられている。回転ドラム７は、本発明の衣類乾燥室に相当する。筐体２の正面側には衣類投入口８が開設されている。衣類投入口８は筐体２の前面の扉５が覆っている。衣類投入口８の内側には、回転ドラム７が回動自在な状態で支持されている。 Next, a schematic configuration of the clothes dryer 1 will be described. As shown in FIG. 2, a rotating drum 7 is provided inside the housing 2 . The rotating drum 7 corresponds to the clothes drying chamber of the present invention. A clothing slot 8 is opened on the front side of the housing 2 . The clothes inlet 8 is covered with a front door 5 of the housing 2.例文帳に追加A rotary drum 7 is rotatably supported inside the clothes inlet 8 .

回転ドラム７は、回転軸線（図示省略）が水平方向となる姿勢で設けられている。筐体２の衣類投入口８側を向く回転ドラム７の端部には、正面開放部９が形成されている。正面開放部９の外周は、リング板１０によって回動自在な状態で筐体２に支持されている。 The rotating drum 7 is provided in a posture in which the axis of rotation (not shown) is horizontal. A front open portion 9 is formed at the end of the rotary drum 7 facing the clothing inlet 8 side of the housing 2 . The outer periphery of the front open portion 9 is rotatably supported by the housing 2 by a ring plate 10 .

回転ドラム７の奥壁１１には、筐体２の支持軸１２が連結されている。回転ドラム７の奥壁１１は、図示しない糸くずフィルタが取り付けられ、回転ドラム７の内外で空気が通過自在となっている。 A support shaft 12 of the housing 2 is connected to a back wall 11 of the rotating drum 7 . A lint filter (not shown) is attached to the rear wall 11 of the rotary drum 7 so that air can pass through the inside and outside of the rotary drum 7 .

回転ドラム７の奥壁１１の外側（背面側）には、回転ドラム７内の空気を筐体２の外部へ導く排湿路１３が設けられている。 Outside (rear side) of the back wall 11 of the rotary drum 7 , a moisture discharge passage 13 is provided for guiding the air inside the rotary drum 7 to the outside of the housing 2 .

排湿路１３は、回転ドラム７の奥壁１１の外側から筐体２の上部の排湿口１４へ向かって延設されている。排湿路１３内には、排湿ファン１５（衣類乾燥用ファン装置）が組み込まれている。 The moisture discharge path 13 extends from the outside of the back wall 11 of the rotary drum 7 toward the moisture discharge port 14 at the top of the housing 2 . A moisture exhaust fan 15 (fan device for drying clothes) is incorporated in the moisture exhaust path 13 .

排湿ファン１５は、その回転により回転ドラム７内の空気を排出すると共に、回転ドラム７内に温風を引き込む気流を発生させる。筐体２の底面には乾燥用空気取り入れ口１６が形成されている。排湿ファン１５が回転すると、外気が乾燥用空気取り入れ口１６から筐体２の内部へ取り込まれる。このとき脚部材３によって筐体２の底部の下方に適度な空隙が形成されるので、筐体２の底面に形成された乾燥用空気取り入れ口１６からの外気の取り入れが円滑に行える。 The dehumidification fan 15 generates an air current that draws warm air into the rotating drum 7 while discharging the air in the rotating drum 7 by its rotation. A drying air intake port 16 is formed in the bottom surface of the housing 2 . When the dehumidification fan 15 rotates, outside air is drawn into the housing 2 through the drying air intake 16 . At this time, since an appropriate space is formed below the bottom of the housing 2 by the leg members 3, external air can be smoothly taken in from the drying air intake 16 formed in the bottom of the housing 2. - 特許庁

筐体２の内部へ取り込まれた外気は、衣類乾燥用空気として後述する衣類乾燥用熱交換器１７を通過し加熱される。衣類乾燥用熱交換器１７で加熱された衣類乾燥用空気は回転ドラム７内へ送られる。 The outside air taken into the housing 2 passes through a clothes drying heat exchanger 17, which will be described later, and is heated as clothes drying air. The clothes drying air heated by the clothes drying heat exchanger 17 is sent into the rotating drum 7 .

そして、回転ドラム７の内部で衣類Ｗの湿気を吸収し、衣類Ｗを乾燥させる。この時回転ドラム７内で発生した湿気は排湿路１３へ送出され、排湿口１４に接続されている図示しない排湿ダクトから筐体２外（例えば屋外）に排出される。 Then, the moisture of the clothes W is absorbed inside the rotary drum 7 and the clothes W are dried. At this time, the moisture generated in the rotary drum 7 is sent to the moisture discharge path 13 and discharged to the outside of the housing 2 (for example, outdoors) through a moisture discharge duct (not shown) connected to the moisture discharge port 14 .

筐体２内には、回転ドラム７および排湿ファン１５を回転させるための乾燥モータ１８と、外気を加熱して衣類乾燥用空気を生成する衣類乾燥用熱交換器１７と、衣類乾燥用空気を回転ドラム７内へ導く乾燥用空気導入路１９とが設けられている。乾燥モータ１８の駆動や衣類乾燥用熱交換器１７への温水供給は、コントローラ２０により制御される。 The housing 2 contains a drying motor 18 for rotating the rotary drum 7 and the dehumidifying fan 15, a clothes drying heat exchanger 17 for heating outside air to generate clothes drying air, and a clothes drying air. and a drying air introduction path 19 for introducing the inside of the rotating drum 7 is provided. A controller 20 controls the driving of the drying motor 18 and the supply of hot water to the clothes drying heat exchanger 17 .

乾燥モータ１８は、二つの駆動軸（第１駆動軸２１、第２駆動軸２２）を備えている。第１駆動軸２１の回転力は、第１伝動ベルト２３を介して回転ドラム７へ伝達され、回転ドラム７を回転させる。 The drying motor 18 has two drive shafts (a first drive shaft 21 and a second drive shaft 22). The rotational force of the first drive shaft 21 is transmitted to the rotating drum 7 via the first transmission belt 23 to rotate the rotating drum 7 .

回転ドラム７の回転は、内部に収容されている衣類Ｗを定位置に止めることなく常に動かすために行われる。第２駆動軸２２の回転力は、第２伝動ベルト２４を介して排湿ファン１５へ伝達され、排湿ファン１５を回転させる。 Rotation of the rotary drum 7 is performed in order to constantly move the clothes W contained therein without stopping in a fixed position. The rotational force of the second drive shaft 22 is transmitted to the dehumidification fan 15 via the second transmission belt 24 to rotate the dehumidification fan 15 .

排湿ファン１５の回転により、回転ドラム７内部に気流が形成される。以上の構成から、筐体２の内部には、乾燥用空気取り入れ口１６を上流端とする乾燥用空気導入路１９と排湿口１４を下流端とする排湿路１３とで、衣類乾燥用空気路２５が形成される。 An air current is formed inside the rotary drum 7 by the rotation of the dehumidification fan 15 . From the above configuration, inside the housing 2, there is a drying air introduction path 19 with the drying air intake 16 at the upstream end and a moisture discharge path 13 with the moisture discharge port 14 at the downstream end for drying clothes. An air passage 25 is formed.

衣類乾燥用熱交換器１７は、回転ドラム７の下方に配設されている。衣類乾燥用熱交換器１７には、温水導入管２６（熱媒供給管）から温水が供給され、温水導出管２７から温水が導出される。 The clothes drying heat exchanger 17 is arranged below the rotating drum 7 . Hot water is supplied to the clothes drying heat exchanger 17 from a hot water introduction pipe 26 (heat medium supply pipe), and hot water is led out from a hot water outlet pipe 27 .

温水導入管２６の始端には導入継手２８を介して図外の給湯装置から延びる給湯往き管２９が接続される。温水導出管２７の終端には導出継手３０を介して図外の給湯装置から延びる給湯戻り管３１が接続される。 A leading end of the hot water supply pipe 26 is connected via an introduction joint 28 to a hot water supply pipe 29 extending from a hot water supply device (not shown). A hot water supply return pipe 31 extending from a hot water supply apparatus (not shown) is connected to the end of the hot water lead-out pipe 27 via a lead-out joint 30 .

温水導入管２６には、分岐部３２を介して暖房用導入管３３（暖房用熱媒管）が接続されている。温水導出管２７には、合流部３４を介して暖房用導出管３５が接続されている。暖房用導入管３３と暖房用導出管３５とは、後述する暖房用熱交換器３６に接続されている。 A heating introduction pipe 33 (heat medium pipe for heating) is connected to the hot water introduction pipe 26 via a branch portion 32 . A heating outlet pipe 35 is connected to the hot water outlet pipe 27 via a junction 34 . The heating introduction pipe 33 and the heating outlet pipe 35 are connected to a heating heat exchanger 36, which will be described later.

筐体２内部には、暖房用熱交換器３６と、温風ファン３７（暖房用ファン装置）とが設けられている。暖房用熱交換器３６は、回転ドラム７の下方に位置し、衣類乾燥用熱交換器１７に隣接して設けられている。 A heating heat exchanger 36 and a warm air fan 37 (heating fan device) are provided inside the housing 2 . The heating heat exchanger 36 is positioned below the rotating drum 7 and provided adjacent to the clothes drying heat exchanger 17 .

筐体２の底面には乾燥用空気取り入れ口１６に隣接して暖房用空気取り入れ口３８が形成されている。更に、筐体２の底面には、暖房用熱交換器３６により加熱された空気の吹き出し口３９が形成されている。 A heating air intake 38 is formed adjacent to the drying air intake 16 on the bottom surface of the housing 2 . Furthermore, the bottom surface of the housing 2 is formed with an outlet 39 for air heated by the heating heat exchanger 36 .

温風ファン３７は、その回転により、暖房用空気取り入れ口３８から外気を暖房用空気として取り込むと共に、暖房用熱交換器３６によって加熱された暖房用空気を吹き出し口３９から室内に送出する。 The warm air fan 37 rotates to take in outside air as heating air from the heating air intake port 38 and to send the heating air heated by the heating heat exchanger 36 into the room from the blowout port 39 .

暖房用熱交換器３６と温風ファン３７とは、暖房用空気取り入れ口３８を上流端とし吹き出し口３９を下流端とする暖房用空気路４０の内部に配設されている。暖房用空気路４０と回転ドラム７内を含む衣類乾燥用空気路２５とは、一部が隣接しているが、互いに連通しておらず隔離されており、暖房用空気と衣類乾燥用空気とが混ざり合うことはない。 The heating heat exchanger 36 and the hot air fan 37 are disposed inside a heating air passage 40 having a heating air intake port 38 as an upstream end and a blowout port 39 as a downstream end. The heating air passage 40 and the clothes drying air passage 25 including the inside of the rotary drum 7 are partially adjacent to each other, but are not communicated with each other and are isolated, so that the heating air and the clothes drying air are separated. are not mixed.

乾燥用空気取り入れ口１６と、暖房用空気取り入れ口３８と、吹き出し口３９とは、１つのフィルタ部材４によって覆われている。図１に示すように、フィルタ部材４は、筐体２底部に取り付けられており、前方に引っ張ることでスライドさせて着脱可能となっている。フィルタ部材４は、通気自在の取り入れ口用開口部４１（暖房用開口部４１ａ，乾燥用開口部４１ｂ）と、下方に張り出す案内部４２とを備えている。 The drying air intake 16 , the heating air intake 38 and the air outlet 39 are covered with one filter member 4 . As shown in FIG. 1, the filter member 4 is attached to the bottom of the housing 2 and can be removed by pulling it forward and sliding it. The filter member 4 includes an air intake opening 41 (heating opening 41a, drying opening 41b) and a guide portion 42 projecting downward.

また、フィルタ部材４には、図３に一部を示すように、取り入れ口用開口部４１を覆うようにして捕捉材４３が取り付けられている。捕捉材４３は、外気に混入している塵埃等を捕捉して乾燥用空気や暖房用空気から塵埃を除去する。 3, a trapping material 43 is attached to the filter member 4 so as to cover the intake opening 41. As shown in FIG. The capturing material 43 captures dust and the like mixed in the outside air and removes the dust from the drying air and the heating air.

案内部４２は、図３に示すように、吹き出し口３９に対応する位置に設けられており、吹き出し口３９から送出される暖房用空気を前方の斜め下方に案内する。これによれば、例えば、暖房用空気を天井から下方に吹き出す場合に比べて、容易に暖房用空気を床面近くに到達させることができ、暖房効率が向上する。 As shown in FIG. 3, the guide portion 42 is provided at a position corresponding to the blowout port 39, and guides the heating air sent out from the blowout port 39 obliquely downward and forward. According to this, for example, compared with the case where the heating air is blown downward from the ceiling, the heating air can be easily made to reach the vicinity of the floor surface, and the heating efficiency is improved.

更に、衣類乾燥機１を図示しない設置台上に設置するときにも、案内部４２に案内された暖房用空気の流れは筐体２の底面に対向する設置台の上面に向くことが抑制され、室内へ良好に送出されて暖房効率の低下が防止される。 Furthermore, even when the clothes dryer 1 is installed on an installation table (not shown), the flow of the heating air guided by the guide part 42 is suppressed from being directed toward the upper surface of the installation table that faces the bottom surface of the housing 2. , the air is well delivered into the room, and the reduction in heating efficiency is prevented.

また、衣類乾燥用熱交換器１７及び暖房用熱交換器３６には、温水導入管２６の始端に設けられた導入継手２８を介して接続された単一の給湯往き管２９から温水が供給される。温水導入管２６の温水は分岐部３２によって、温水導入管２６と暖房用導入管３３とに分流される。 Hot water is supplied to the clothes drying heat exchanger 17 and the heating heat exchanger 36 from a single hot water supply pipe 29 connected via an introduction joint 28 provided at the beginning of the hot water introduction pipe 26 . be. The hot water in the hot water introduction pipe 26 is divided by the branch 32 into the hot water introduction pipe 26 and the heating introduction pipe 33 .

分岐部３２の下流側の温水導入管２６には、熱動弁等の乾燥用弁装置４４が介設されており、暖房用導入管３３には、熱動弁等の暖房用弁装置４５が介設されている。乾燥用弁装置４４と暖房用弁装置４５とは夫々、コントローラ２０により制御される。 A drying valve device 44 such as a thermal valve is interposed in the hot water introduction pipe 26 on the downstream side of the branch portion 32, and a heating valve device 45 such as a thermal valve is installed in the heating introduction pipe 33. interposed. The drying valve device 44 and the heating valve device 45 are controlled by the controller 20, respectively.

ここで、本実施形態の衣類乾燥機による衣類乾燥運転と暖房運転とについて説明する。コントローラ２０は、図４に示すように、衣類乾燥運転制御部４６と暖房運転制御部４７とを機能的に備えている。衣類乾燥運転制御部４６は、衣類乾燥時間が設定された乾燥タイマ４８を備えており、暖房運転制御部４７は、暖房時間が設定された暖房タイマ４９を備えている。 Here, the clothes drying operation and the heating operation of the clothes dryer of this embodiment will be described. The controller 20 functionally includes a clothes drying operation control section 46 and a heating operation control section 47, as shown in FIG. The clothes drying operation control unit 46 has a drying timer 48 in which the clothes drying time is set, and the heating operation control unit 47 has a heating timer 49 in which the heating time is set.

衣類乾燥運転制御部４６には、乾燥運転スイッチ５０（図２参照）の操作信号（ＯＮ／ＯＦＦ信号）が入力され、これに応じて衣類乾燥運転制御部４６は、乾燥用弁装置４４及び乾燥モータ１８を制御する。暖房運転制御部４７には、暖房運転スイッチ５１（図２参照）の操作信号（ＯＮ／ＯＦＦ信号）が入力され、これに応じて暖房運転制御部４７は、暖房用弁装置４５及び温風ファン３７を制御する。 An operation signal (ON/OFF signal) of a drying operation switch 50 (see FIG. 2) is input to the clothes drying operation control unit 46. Control the motor 18 . An operation signal (ON/OFF signal) of a heating operation switch 51 (see FIG. 2) is input to the heating operation control unit 47, and in response to this, the heating operation control unit 47 operates the heating valve device 45 and the hot air fan. 37.

即ち、乾燥運転スイッチ５０をＯＮ操作して衣類乾燥運転を開始すると、衣類乾燥運転制御部４６は、乾燥用弁装置４４を開弁させて温水を衣類乾燥用熱交換器１７へ供給する。次いで、衣類乾燥運転制御部４６は、乾燥モータ１８を作動させ、回転ドラム７と排湿ファン１５とを回転させる。これにより、回転ドラム７内の衣類は回転しながら供給される乾燥用空気により乾燥され、衣類から生じた湿気は排湿ファン１５によって筐体２外（例えば屋外）へ排出される。 That is, when the drying operation switch 50 is turned ON to start the clothes drying operation, the clothes drying operation control section 46 opens the drying valve device 44 to supply warm water to the clothes drying heat exchanger 17 . Next, the clothes drying operation control unit 46 operates the drying motor 18 to rotate the rotating drum 7 and the dehumidifying fan 15 . As a result, the clothes in the rotating drum 7 are dried by the drying air that is supplied while rotating, and the moisture generated from the clothes is discharged to the outside of the housing 2 (for example, outdoors) by the moisture exhaust fan 15 .

衣類乾燥運転は、通常、予め衣類の乾燥時間をセットした乾燥タイマ４８のタイムアップにより停止する。乾燥タイマ４８がタイムアップすると、衣類乾燥運転制御部４６は、乾燥運転スイッチ５０のＯＦＦ操作がなくても乾燥用弁装置４４及び乾燥モータ１８を停止させ、衣類乾燥運転を終了させる。乾燥運転スイッチ５０のＯＦＦ操作を行うことによっても、衣類乾燥運転制御部４６は、乾燥用弁装置４４及び乾燥モータ１８を停止させるので、衣類乾燥運転を終了させることができる。 The clothes drying operation is normally stopped when the drying timer 48, in which the clothes drying time is set in advance, times out. When the drying timer 48 times out, the clothes drying operation control section 46 stops the drying valve device 44 and the drying motor 18 even if the drying operation switch 50 is not turned off, and terminates the clothes drying operation. By turning off the drying operation switch 50, the clothes drying operation control section 46 also stops the drying valve device 44 and the drying motor 18, so that the clothes drying operation can be terminated.

また、暖房運転スイッチ５１をＯＮ操作して暖房運転を開始すると、暖房運転制御部４７は、暖房用弁装置４５を開弁させて温水を暖房用熱交換器３６へ供給し、温風ファン３７を作動させる。これにより、暖房用熱交換器３６によって加熱された暖房用空気は室内に送出される。 Further, when the heating operation switch 51 is turned ON to start the heating operation, the heating operation control unit 47 opens the heating valve device 45 to supply hot water to the heating heat exchanger 36, and the warm air fan 37 to activate. As a result, the heating air heated by the heating heat exchanger 36 is delivered indoors.

暖房運転は、予め暖房時間をセットした暖房タイマ４９のタイムアップにより停止し、或いは、暖房運転スイッチ５１のＯＦＦ操作を行うことにより停止する。暖房タイマ４９がタイムアップすると、暖房運転制御部４７は、暖房用弁装置４５及び温風ファン３７を停止させ、暖房運転を終了させる。暖房運転スイッチ５１をＯＦＦ操作した時には、その時点で暖房運転制御部４７は、暖房用弁装置４５及び温風ファン３７を停止させて暖房運転を終了させる。 The heating operation is stopped when the heating timer 49 for which the heating time is set in advance expires, or when the heating operation switch 51 is turned off. When the heating timer 49 times out, the heating operation control unit 47 stops the heating valve device 45 and the warm air fan 37 to terminate the heating operation. When the heating operation switch 51 is turned off, the heating operation control unit 47 stops the heating valve device 45 and the warm air fan 37 at that time to end the heating operation.

このように、衣類乾燥運転制御部４６と暖房運転制御部４７とは、互いに影響を受けることなく夫々独立して衣類乾燥運転制御と暖房運転制御とを実行する。従って、衣類乾燥運転と暖房運転とのうち何れか一方のみを所望に応じて行うことができ、衣類乾燥運転と暖房運転とを同時に行うこともできる。 In this manner, the clothes drying operation control unit 46 and the heating operation control unit 47 independently perform the clothes drying operation control and the heating operation control without being affected by each other. Therefore, only one of the clothes drying operation and the heating operation can be performed as desired, and the clothes drying operation and the heating operation can be performed at the same time.

なお、本実施形態においては、衣類乾燥室として回転ドラム７を採用したが、これに限るものではない。また、本実施形態においては、回転ドラム７と排湿ファン１５とを単一のモータ（乾燥モータ１８）で駆動しているが、これに限らず、回転ドラムと排湿ファンとを夫々独立したモータで回転駆動してもよい。また、衣類乾燥用熱交換器１７と暖房用熱交換器３６とは温水を熱媒とした例を示したが、これに限らず、他の熱媒を用いてもよい。 In this embodiment, the rotary drum 7 is used as the clothes drying chamber, but the drying chamber is not limited to this. Further, in the present embodiment, the rotating drum 7 and the dehumidifying fan 15 are driven by a single motor (drying motor 18). It may be rotationally driven by a motor. Also, although the clothes drying heat exchanger 17 and the heating heat exchanger 36 use hot water as the heat medium, the heat medium is not limited to this, and other heat medium may be used.

また、本実施形態においては、各タイマ（乾燥タイマ４８、暖房タイマ４９）のタイムアップによって衣類乾燥運転や暖房運転を終了させる例を示したが、これに限るものではない。例えば、温度センサや湿度センサの検出値が設定値に達したときに衣類乾燥運転や暖房運転を終了させてもよい。 Further, in the present embodiment, an example is shown in which the clothes drying operation and the heating operation are terminated when the respective timers (the drying timer 48 and the heating timer 49) time up, but the present invention is not limited to this. For example, the clothes drying operation and the heating operation may be ended when the detected value of the temperature sensor or humidity sensor reaches the set value.
