Description

【0001】
【発明の属する技術分野】
手持ち運搬移動可能な小さな除湿機に於いて、部品点数の削減、箱体強度の向上、振動騒音の低減等に関するものである。
【0002】
【従来の技術】
従来の除湿機の箱体構造を図9、図10により説明する。101は従来の除湿機の前箱、102は後箱で互いに組合わせると上部面が開口するよう形成されている。103は上部面の開口を閉鎖する上面板で、これらの3者を組合わせることによって除湿機の箱体を形成する。
104は露受であり、該露受104には蒸発器105、凝縮器106、ファンモータ107等がネジ等の固定方法により載置され、該露受104は上記前箱101にネジ等の固定方法により装着されている。108はファンダクト、109は圧縮機で鋼板製等の丈夫なベース110に組込まれ、前記前箱101の下部側面及び前後面にネジ等の固定方法により装着されている。111は水受タンク、112は圧縮機の吸込管、113は圧縮機の吐出管である。
【0003】
かかる除湿機の箱体の組立作業を説明すると、前箱101に圧縮機109を組込んだベース110をネジ等で装着し、次に露受104に蒸発器105、凝縮器106、ファンモータ107、ファンダクト108等をネジ等の手段により固着し、前記前箱101の内部にネジ等の方法により装着し、かつ一方の後箱102及び上面板103をネジ等の固定により装着し、組立作業を終了する。
【0004】
なお、この種の除湿機の公知例としては、特開昭60−62537号公報、実開平6−40729号公報が挙げられる。
【0005】
【発明が解決しようとする課題】
従来の除湿機においては、前箱、後箱、上面板、ベースに分離されているので、結合部分が多く、ネジ止め作業が多く、ベースや結合部分にビレ音が発生する欠点があった。しかも必要な部品の点数が多くて取付け作業性が劣るという問題があった。また、前箱と後箱が前後分離形形状であるため箱体前後の結合強度が弱く、この結合部に圧縮機などの大きな荷重に加えて輸送時若しくは運搬時に衝撃が加わった場合は、結合部が外れる若しくは結合部が破損する可能性があり、前箱と後箱が分離しやすいという問題があった。
【0006】
さらには、振動、騒音源の圧縮機をベースだけで固定していることと、圧縮機の吸込管や吐出管が圧縮機の周囲に配設、すなわち圧縮機の中心軸から離れて配設していること等により圧縮機の振動が減衰されず、吸込管や吐出管の振動も拡大されるので振動、騒音が大きいという問題があった。
【0007】
また、吸込管に附着する露が圧縮機を伝わって落下し、畳を汚すという問題もあった。
【0008】
さらには、水受タンクは後箱の下部側のみに配設されているので容量的に小さく、水受タンクが直ぐ満杯になり、たびたび排水処理をしなければならないという問題があった。
【0009】
さらには、水受タンクを下箱に挿着した際、水受タンク内の水量が少ないときに水受タンクと下箱との接触部分でビレ音が発生する問題があった。また、水受タンクが下箱に確実に挿入されたか分からないという問題もあった。
【0010】
さらには、空気吸込口は前箱の前面のみにしかないので、前箱の前面に物品が置かれた場合、除湿性能が悪くなるという問題もあった。また、空気吸込口を蒸発器側面に対面して設けたものにあっては、空気吸込口から入った異物が蒸発器側面に当たり、蒸発器を壊すという問題もあった。
【0011】
【課題を解決するための手段】
上記の問題は、底板部を有する一体成形品で内側に圧縮機を収納した下箱と、外表面に通風口を有し、この通風口に連通して内側に蒸発器、凝縮器および送風機を配置した上箱と、この上箱と下箱とに外郭が形成された箱体と、前記下箱の外側前面に水受タンクを設けた除湿機において、前記上箱は、前面部をパネル状、後部を箱体部として構成し、このパネル状の前面部と箱体部間を複数のリブで接続することにより、上記前面部と箱体部間に空間を設けてフィルターを収納可能にすると共に、上部および左右の3方向に空気吸込口を設けた除湿機とすることにより解決される。
【0012】
【発明の実施の形態】
湿機の箱体を上下方向に上箱と下箱との2分割構成とし、下箱は底板部を有する一体成形品で内側に圧縮機を収納し、上箱は外表面に通風口を設け、この通風口に連通して内側に蒸発器、凝縮器および送風機を配置すると共に、下箱の外側前面に水受タンクを設置したものである。これによって、ネジ止め作業を少なくし、部品点数を少なくして取付け作業性を向上させた。また、底面および外周が一体の下箱に重量の重い圧縮機を収納したので箱体が安定し、一体形にしたので複数部品の接合部がなくなるためビレ音がなくなり、箱体強度が増し、輸送時若しくは運搬時に箱体が分離するという問題も解消することができる。また、下箱の一体形により、吸込管に附着した露の滴下による床面への水洩れも解消することができる。
【0013】
さらには、圧縮機と蒸発器、凝縮器を接続する、吸込管および吐出管のループ状配管部を、圧縮機の上部で圧縮機の中心軸線に近接して配設したものである。
【0014】
これによって、震動源である圧縮機が重量の大きい一体形の下箱に固定されるので圧縮機の振動が減衰され、吸込管と吐出管が圧縮機の中心軸線に近接したことによって吸込管と吐出管の振動も少なくなり、箱体全体の振動、騒音を小さくすることができる。
【0015】
さらには、水受タンクは略U字形断面形状とし、下箱の前面部に圧縮機を囲うように配置すると共に、透明ないし半透明材料で製作することにより、除湿機の面および左右両面の3方向より水受タンク内の水量が見えるようにしたものである。これによって、従来の水受タンクに加えて両側部の容積分だけタンク容積が大きくなり、満タンになる時間が延び、タンクの排水処理回数を減らすことができる。また、水受タンクの水位を一方向からしか確認出来なかったものを3方向から確認できる。
【0016】
さらには、水受タンクの底面部の下側に、下箱と一体または別部品にて受台を設け、且つ、この受台の一部にU字状切欠き穴を設けて板バネ状舌片部を成形し、この板バネ状舌片部に水受タンクの底面部を当接させるようにしたものである。これによって、水受タンクを板バネが常時上側へ押す力が作用し、水受タンクのビレ音を解消することができる。
また、水受タンクの下箱への挿入感覚が分かり、水受タンクが下箱に確実に挿入されたことが確認できる。また、板バネ18は下箱2の底板で形成し、板バネとして別部品を使わないので価格的に安くできる。
【0017】
さらには、上箱は、前面部をパネル状、後部を箱体部として構成し、該パネル状の前面部と箱体部間を複数のリブで接続することにより、上記前面部と箱体部間に空間を設けてフィルターを収納可能にすると共に、上部および左右の3方向に空気吸込口を設けたものである。これによって、室内空気の吸込口を従来の前面1方向から上面および両側面の3方向にすることができ、室内の除湿を均一に満遍なくできると共に、除湿機の設置場所が拡大できる。即ち、除湿機の前や側面に障害物があっても、3方向のいずれか側が空いていればよく、更に、前面パネル状部に空気吸込口を設ければ4面吸込みにもできる。また、前面パネル状部は自由にデザインできる等のデザイン的メリットもある。
【0018】
さらには、上箱の上部および左右の3方向に設けた空気吸込口と蒸発器との間に、蒸発器の上部および側面部をカバーする曲げダクト部を上箱と一体に成形したものである。これによって、空気吸込口が3面に形成されるため箱体の前面が物品で遮蔽されても除湿機の除湿性能が低下することがない。また、蒸発器側面に対面した空気吸込口に曲げダクトが形成されるため吸込口から異物が入っても異物が蒸発器に当たらず、蒸発器を壊すという問題は解消できる。
【0019】
さらには、下箱の略中央部に圧縮機を設置すると共に、圧縮機より前方の下箱上部に露受および蒸発器、凝縮器を配置することにより、圧縮機の上部に圧縮機が取付け、取り外し可能な空間を設けたことにより、圧縮機、蒸発器、凝縮器および上箱が全て上から積上げ方式で順次組立てることが可能となり、組立性の良い構造となる。
【0020】
以下、本発明の詳細を図に示す一実施例で説明する。
【0021】
図1は除湿機の要部縦断面図、図2は除湿機の組立分解斜視図、図3は圧縮機の配管説明図、図4は図1のA−A断面図、図5は下箱凹部と水受タンク凸部の断面図、図6、図7、図8は3方向吸込部の断面図で、図2の上箱B−B、C−C、D−D断面図である。
【0022】
図1及び図2を用いて、本発明の除湿機の構造を説明する。1は上箱、2は下箱であり、この上箱1と下箱2が結合して除湿機の外郭を形成するものである。上箱1も下箱2もプラスチック射出等による一体成形で作られており、下箱2の内部には圧縮機3と水受タンク4が収納できるようになっている。
【0023】
圧縮機3は圧縮機下部に取付けた取付足により防振ゴム等を介して下箱2に固定される。また圧縮機3には冷凍サイクルの一部をなす吸込管5と吐出管6が収納されている。水受タンク4は下箱2の前面部に圧縮機3を囲うように配設され、U字形断面形状を有している。7は露受であり、下箱2の上部で、上箱1に収納した蒸発器8に対応する位置に配設され、蒸発器8に附着した露を受けるものである。蒸発器8は上箱1の前部に収納されている。9は凝縮器であり、凝縮器9は蒸発器8と並んで蒸発器8の後部に収納されている。
【0024】
10はファンモータ、11はファンであり、これらは上箱1に収納されている。12は前面吸込口であり、上箱1の前面下部に配設されている。13は3方向吸込口であり、3方向吸込口13は上箱1の上面前部と上箱1の両側前部の計3ヶ所に配設されている。14は吐出口であり、吐出口14は上箱1の上面後部に配設されている。15は凹部であり、この凹部は下箱2の底部に設けたものである。16は凸部であり、この凸部は水受タンク4の下面に設けたものである。17は係合部であり、除湿機本体を2分割する位置にあり、上箱1と下箱2をこの位置で係合している。20は蒸発器前面ダクトであり、蒸発器8の前面と上箱1の前面との間に形成したものである。
【0025】
上記の如く、除湿機の箱体構造に於いて、プラスチック射出成形等にて除湿機の箱体を上下方向に上箱と下箱で2分割し、下箱は一体形で圧縮機、水受タンク及び露受が収納できるようにしたものである。これによって、従来使っていた前箱、後箱、上面板、ベースは上箱、下箱の2部品ですむようになり、部品点数が低減し、軽量化された。ネジ止め作業は大幅に低減し、組立量も低減した。また、下箱に重量の重い圧縮機を収納、固定したことにより箱体が安定し、一体形にしたのでビレ音がなくなり、箱体の強度が増し、輸送時の輸送強度も向上した。また、下箱の一体形により、吸込管に附着した露の滴下による水洩れも解消することができた。
【0026】
さらに、圧縮機3と蒸発器8、凝縮器9を結ぶ吸込管5と吐出管6のループ状配管部を図3に示す如く、圧縮機3の上部で、圧縮機3の中心軸に近接して配設したものである。
これによって、従来、圧縮機をベース板1枚で固定したものが一体形形状の下箱でしっかり固定されるようになり圧縮機の振動、騒音が大幅に低減した。また、従来、圧縮機から出る配管が圧縮機の外周部で中心軸から離れた位置に配設されていたので配管の振動、騒音が大きいという問題があったが、本発明のように圧縮機の中心軸に近接して配設したことによって圧縮機の吸込管と吐出管の振動、騒音を大幅に低減した。
【0027】
さらに、図4に示す如く、水受タンク4はU字形断面形状とし、下箱2の前面部に圧縮機3を囲うように配設したものである。これによって、従来、水受タンクは前面側のみを利用した矩形形状のため内容積が小さいものであったが、本発明のように下箱2の前面部に圧縮機3を囲うようにし、両側面も利用したU字形断面形状にしたのでタンク容積が大きくなり、満タンになる時間が延び、タンクの排水処理回数を減らすことができた。また、水受タンクの水位を1方向からしか確認できなかったものを3方向から確認できるという効果も得られた。
【0028】
さらには、図5に示す如く、下箱2と一体に凹部15を有する板バネ18を形成し、この凹部15と水受タンク4の下部に設けた凸部16とが係合できるようにしたものである。これによって、水受タンクを板バネが常時上側へ押す力が作用し、水受タンクのビレ音を解消することができた。また、水受タンクの下箱への挿入感覚が分かり、水受タンクが下箱に確実に挿入されたことが確認できた。また、板バネ18は下箱2の底板で形成し、板バネとして別部品を使わないので価格的に安くできた。なお、下箱と一体に凹部ではなく、凸部を有する板バネを形成し、水受タンクの下部には凸部ではなく凹部を形成することも可能である。
【0029】
さらには、図6、図7、図8に示す如く、上箱1の上面と両側面にも蒸発器8の上面及び側面に対向した位置に空気吸込口13を設け、この空気吸込口13から蒸発器前面ダクト20に通ずる位置に蒸発器8の上面及び側面をカバーする形の曲げダクト19、21、22にしたものである。これによって、上箱1の前面に設けた空気吸込口12の他に、上箱1の上面と両側面の3面に空気吸込口13が形成されるため、箱体の前面が物品で遮蔽されても、この3面から空気が吸込まれ、除湿機の除湿性能が低下することは起こらない。また、蒸発器の上面及び側面に対面した空気吸込部に曲げダクトが形成されるため吸込口から異物が入っても曲げダクトでガードされ蒸発器の側面に当たることがないので、蒸発器を壊すという問題も解消できた。
【0030】
本発明の除湿機は、除湿機の箱体を上下方向に上箱と下箱で2分割し、下箱は一体形で圧縮機、水受タンク及び露受を収納できるようにしたものであるから、軽量化でき、部品点数が減り、部品費、組立費が低減できる。また、下箱は一体形なので箱体のビレ音がなく、圧縮機の吸込管に附着した露の滴下、水洩れ等がなく、強度が大きく、輸送強度も大きくなる効果がある。
【0031】
さらに、圧縮機と蒸発器、凝縮器を接続する、吸込管および吐出管のループ状配管部を、圧縮機の上部で圧縮機の中心軸に近接して配設したものは、圧縮機の振動が減衰され、配管振動も低減し、除湿機の振動、騒音が低減できる効果がある。
【0032】
さらに、水受タンクはU字形断面形状とし、下箱の前面部に圧縮機を囲うように配設したものは、水受タンクの容積が大きくでき、排水回数を減らすことができる。また、水位を3方向から確認することができる効果がある。
【0033】
さらに、下箱と一体に板バネを形成し、この板バネに水受タンクの下部を係合できるようにしたものは、水受タンクのビレ音が解消でき、水受タンクを下箱へ挿入する際、挿入感覚が分かり、水受タンクを確実に下箱に挿入できる。また、板バネを別部品を使わない板バネ式によりコスト低減の効果がある。
【0034】
さらに、上箱の前面の下部に空気吸込口を設けると共に、上箱の上面と両側面にも蒸発器の上面及び側面に対向した位置に空気吸込口を設け、この空気吸込口から蒸発器前面ダクトに通ずる位置に、蒸発器の上面及び側面をカバーする形の曲げダクトを設けたものは、除湿機の前面が物等で遮蔽されても上面と両側面の空気吸込口から室内空気を吸込み除湿機の性能を確保できると共に、上面と両側面の空気吸込口から異物が入っても蒸発器側面には直接当たらないため蒸発器を壊すことがない等の効果がある。
【0035】
【発明の効果】
本発明によれば、前箱の前面に物品が置かれた場合、除湿性能を改善できるという効果を奏する。

BACKGROUND OF THE INVENTION
In a small dehumidifier that can be hand-carried and moved, it relates to reduction of the number of parts, improvement of box strength, reduction of vibration noise, and the like.
[0002]
[Prior art]
A box structure of a conventional dehumidifier will be described with reference to FIGS. 101 is a front box of a conventional dehumidifier, and 102 is a rear box. When combined with each other, the upper surface is opened. Reference numeral 103 denotes an upper plate that closes the opening on the upper surface, and a box of the dehumidifier is formed by combining these three members.
104 is a dew holder, and an evaporator 105, a condenser 106, a fan motor 107, and the like are placed on the dew holder 104 by screws or the like, and the dew holder 104 is fixed to the front box 101 with screws or the like. It is mounted by the method. 108 is a fan duct, 109 is a compressor, and is assembled in a strong base 110 made of steel plate or the like, and is attached to the lower side surface and front and rear surfaces of the front box 101 by screws or the like. 111 is a water receiving tank, 112 is a suction pipe of the compressor, and 113 is a discharge pipe of the compressor.
[0003]
The assembly work of the box body of such a dehumidifier will be described. A base 110 incorporating a compressor 109 is attached to the front box 101 with screws or the like, and then an evaporator 105, a condenser 106, and a fan motor 107 are attached to the dew holder 104. The fan duct 108 and the like are fixed by means such as screws, and are attached to the inside of the front box 101 by means of screws or the like, and the one rear box 102 and the upper surface plate 103 are attached by fixing screws or the like. Exit.
[0004]
Known examples of this type of dehumidifier include JP-A-60-62537 and JP-A-6-40729.
[0005]
[Problems to be solved by the invention]
Since the conventional dehumidifier is separated into the front box, the rear box, the top plate, and the base, there are many coupling parts, many screwing operations, and the base and the coupling part have a drawback that a cracking sound is generated. Moreover, there is a problem that the number of necessary parts is large and the mounting workability is inferior. In addition, since the front and rear boxes are separated from each other in the front and rear boxes, the bonding strength between the front and rear of the box is weak, and if this joint is subjected to impacts during transportation or transportation in addition to a large load such as a compressor, There is a possibility that the part may come off or the joint part may be damaged, and the front box and the rear box are easily separated.
[0006]
Furthermore, the compressor of the vibration and noise source is fixed only by the base, and the suction pipe and discharge pipe of the compressor are arranged around the compressor, that is, arranged away from the central axis of the compressor. As a result, the vibration of the compressor is not attenuated, and the vibration of the suction pipe and the discharge pipe is also enlarged.
[0007]
In addition, there is a problem that dew attached to the suction pipe falls through the compressor and soils the tatami mat.
[0008]
Furthermore, since the water receiving tank is disposed only on the lower side of the rear box, there is a problem in that the capacity is small, the water receiving tank becomes full immediately, and drainage treatment is often required.
[0009]
Further, when the water receiving tank is inserted into the lower box, there is a problem that a cracking sound is generated at a contact portion between the water receiving tank and the lower box when the amount of water in the water receiving tank is small. There is also a problem that it is not known whether the water receiving tank is securely inserted into the lower box.
[0010]
Furthermore, since the air suction port is only on the front surface of the front box, there is a problem that the dehumidifying performance is deteriorated when an article is placed on the front surface of the front box. Further, in the case where the air suction port is provided so as to face the side surface of the evaporator, there is a problem that foreign matter entering from the air suction port hits the side surface of the evaporator and breaks the evaporator.
[0011]
[Means for Solving the Problems]
The above problem is that the bottom box part is an integrally molded product that has a compressor box inside and has a vent on the outer surface, and communicates with the vent on the inside with an evaporator, condenser, and blower. In the dehumidifier provided with a water receiving tank on the outer front surface of the upper box, the box body in which the outer box is formed in the upper box and the lower box, and the outer front surface of the lower box, the upper box has a front panel shape The rear part is configured as a box part, and the panel-like front part and the box part are connected by a plurality of ribs, thereby providing a space between the front part and the box part so that the filter can be accommodated. At the same time, the problem is solved by using a dehumidifier having air inlets in the upper and left and right directions.
[0012]
DETAILED DESCRIPTION OF THE INVENTION
A box body of dehumidifier is divided into two pieces of an upper box and a lower box in the vertical direction, the lower box accommodating the compressor inwardly integrally molded article having a bottom plate portion, the upper box ventilation holes on the outer surface And an evaporator, a condenser and a blower are arranged on the inner side in communication with the ventilation port, and a water receiving tank is installed on the outer front surface of the lower box. As a result, the screwing work is reduced, the number of parts is reduced, and the mounting workability is improved. In addition, since the heavyweight compressor is stored in the bottom box with the bottom and outer periphery integrated, the box body is stable, and since it is integrated, there are no joints of multiple parts, so there is no cracking noise, and the box body strength increases, The problem that the box is separated during transportation or transportation can also be solved. In addition, due to the integral form of the lower box, water leakage to the floor due to dripping of dew attached to the suction pipe can be eliminated.
[0013]
Further, a suction pipe and a discharge pipe loop-like piping section connecting the compressor, the evaporator, and the condenser are arranged in the upper part of the compressor in the vicinity of the central axis of the compressor.
[0014]
As a result, the compressor, which is a vibration source, is fixed to the heavy-weight integrated lower box, so that the vibration of the compressor is damped, and the suction pipe and the discharge pipe are close to the central axis of the compressor. The vibration of the discharge pipe is also reduced, and the vibration and noise of the entire box can be reduced.
[0015]
Furthermore, the water receiving tank has a substantially U-shaped cross-sectional shape, and is disposed so as to surround the compressor on the front surface of the lower box, and is made of a transparent or translucent material. The amount of water in the water receiving tank can be seen from the direction. As a result, in addition to the conventional water receiving tank, the tank volume is increased by the volume of both sides, the time for filling up is extended, and the number of times of drainage treatment of the tank can be reduced. Moreover, what could confirm the water level of the water receiving tank only from one direction can be confirmed from three directions.
[0016]
Furthermore, a pedestal is provided on the lower side of the bottom portion of the water receiving tank as an integral part of the lower box or as a separate part, and a U-shaped notch hole is provided in a part of the pedestal to provide a leaf spring-like tongue. One piece is formed, and the bottom portion of the water receiving tank is brought into contact with the leaf spring-like tongue piece. As a result, a force that the leaf spring always pushes the water receiving tank upward is applied, and the blur sound of the water receiving tank can be eliminated.
Moreover, it is possible to confirm the insertion feeling of the water receiving tank into the lower box, and to confirm that the water receiving tank is securely inserted into the lower box. Further, the leaf spring 18 is formed by the bottom plate of the lower box 2, and no separate parts are used as the leaf spring, so that the price can be reduced.
[0017]
Further, the upper box is configured such that the front part is a panel and the rear part is a box part, and the front part and the box part are connected by connecting a plurality of ribs between the panel-like front part and the box part. A space is provided between the filters so that the filter can be accommodated, and air inlets are provided in the upper and left and right directions. As a result, the indoor air suction port can be changed from the conventional front surface 1 direction to the upper surface and the both side surfaces in three directions, so that the indoor dehumidification can be made even and uniform and the installation location of the dehumidifier can be expanded. That is, even if there is an obstacle in front of the dehumidifier or on the side surface, it is sufficient that one side in any of the three directions is vacant. Further, if an air suction port is provided in the front panel-like portion, four-surface suction can be achieved. In addition, there is a design advantage that the front panel portion can be freely designed.

Furthermore, a bent duct portion that covers the upper portion and the side surface portion of the evaporator is formed integrally with the upper box between the upper portion of the upper box and the air suction port provided in the left and right three directions and the evaporator. . Thereby, since the air inlet is formed on three surfaces, the dehumidifying performance of the dehumidifier does not deteriorate even if the front surface of the box is shielded by the article. In addition, since a bent duct is formed at the air suction port facing the side surface of the evaporator, even if foreign matter enters from the suction port, the foreign matter does not hit the evaporator, and the problem of breaking the evaporator can be solved.
[0019]
Furthermore, a compressor is installed at the upper part of the compressor by installing a compressor at a substantially central part of the lower box, and arranging a dew, evaporator and condenser at the upper part of the lower box in front of the compressor.

Reference numeral 17 denotes an engaging portion, which is located at a position where the dehumidifier body is divided into two, and the upper box 1 and the lower box 2 are engaged at this position. An evaporator front duct 20 is formed between the front face of the evaporator 8 and the front face of the upper box 1.
[0025]
As described above, in the box structure of the dehumidifier, the box of the dehumidifier is divided into the upper box and the lower box in the vertical direction by plastic injection molding, etc., and the lower box is integrated into the compressor and water receiver. The tank and dew can be stored. As a result, the front box, the rear box, the top plate, and the base, which have been used in the past, can be composed of two parts, an upper box and a lower box, reducing the number of parts and reducing the weight. Screwing work has been greatly reduced, and the amount of assembly has also been reduced. In addition, by storing and fixing a heavy compressor in the lower box, the box became stable and integrated, so there was no cracking noise, the strength of the box increased, and the transport strength during transport also improved. Moreover, water leakage due to the dripping of dew attached to the suction pipe could be eliminated by the integrated form of the lower box.
[0026]
Further, the loop-like piping portion of the suction pipe 5 and the discharge pipe 6 connecting the compressor 3 to the evaporator 8 and the condenser 9 is close to the central axis of the compressor 3 at the upper part of the compressor 3 as shown in FIG. Arranged.
As a result, a conventional compressor fixed with a single base plate is firmly fixed with an integrated lower box, and the vibration and noise of the compressor are greatly reduced. Conventionally, since the piping from the compressor has been disposed at a position away from the central axis at the outer peripheral portion of the compressor, there has been a problem that vibration and noise of the piping are large. By arranging it close to the center axis of the compressor, the vibration and noise of the suction pipe and discharge pipe of the compressor are greatly reduced.
[0027]
Furthermore, as shown in FIG. 4, the water receiving tank 4 has a U-shaped cross-sectional shape and is disposed so as to surround the compressor 3 on the front surface portion of the lower box 2. Thus, conventionally, the water receiving tank has a rectangular shape utilizing only the front side, and thus the inner volume is small. However, as in the present invention, the compressor 3 is enclosed by the front portion of the lower box 2 and the both sides are disposed. The U-shaped cross-section that also used the surface increased the tank volume, extending the time to fill up, and reducing the number of tank wastewater treatments. Moreover, the effect that the water level of the water receiving tank that could only be confirmed from one direction could be confirmed from three directions was also obtained.
[0028]
Further, as shown in FIG. 5, a leaf spring 18 having a recess 15 is formed integrally with the lower box 2 so that the recess 15 can be engaged with a protrusion 16 provided in the lower portion of the water receiving tank 4. Is. As a result, a force that the leaf spring always pushes the water receiving tank upward acts, and the blur sound of the water receiving tank can be eliminated. In addition, the sense of insertion into the lower box of the water receiving tank was understood, and it was confirmed that the water receiving tank was securely inserted into the lower box. In addition, the leaf spring 18 is formed by the bottom plate of the lower box 2, and no separate parts are used as the leaf spring. It is also possible to form a leaf spring having a convex part instead of a concave part integrally with the lower box, and form a concave part instead of the convex part at the lower part of the water receiving tank.
[0029]
Further, as shown in FIGS. 6, 7, and 8, air suction ports 13 are provided on the upper surface and both side surfaces of the upper box 1 at positions facing the upper surface and side surfaces of the evaporator 8. The bent ducts 19, 21 and 22 are formed so as to cover the upper and side surfaces of the evaporator 8 at a position communicating with the evaporator front duct 20. As a result, in addition to the air suction port 12 provided on the front surface of the upper box 1, air suction ports 13 are formed on the upper surface and both side surfaces of the upper box 1, so that the front surface of the box body is shielded by the article. However, air is sucked in from these three surfaces, and the dehumidifying performance of the dehumidifier does not deteriorate. Also, because a bent duct is formed in the air suction part facing the top and side surfaces of the evaporator, even if foreign matter enters from the suction port, it is guarded by the bending duct and does not hit the side of the evaporator, so the evaporator is broken The problem was solved.
[0030]
In the dehumidifier of the present invention, the box body of the dehumidifier is vertically divided into two parts, an upper box and a lower box, and the lower box is integrated so that the compressor, the water receiving tank and the dew can be accommodated. Therefore, the weight can be reduced, the number of parts can be reduced, and the parts and assembly costs can be reduced. Further, since the lower box is integrated, there is no cracking sound of the box, there is no dripping of the dew attached to the suction pipe of the compressor, water leakage, etc., and there is an effect that the strength is high and the transport strength is also increased.
[0031]
Furthermore, a suction pipe and a discharge pipe loop-like piping section connecting the compressor, evaporator and condenser are arranged close to the compressor central axis at the top of the compressor. Is attenuated, pipe vibration is also reduced, and vibration and noise of the dehumidifier can be reduced.
[0032]
Further, the water receiving tank having a U-shaped cross section and disposed so as to surround the compressor at the front portion of the lower box can increase the volume of the water receiving tank and reduce the number of times of drainage. Moreover, there exists an effect which can confirm a water level from 3 directions.
[0033]
Furthermore, a leaf spring is formed integrally with the lower box, and the lower part of the water receiving tank can be engaged with this leaf spring. This eliminates the cracking sound of the water receiving tank, and the water receiving tank is inserted into the lower box. When you do this, you can understand the insertion sensation, and the water receiving tank can be securely inserted into the lower box. In addition, the leaf spring type that does not use a separate part for the leaf spring is effective in reducing the cost.
[0034]
Furthermore, an air suction port is provided at the lower part of the front surface of the upper box, and air suction ports are provided on the upper surface and both side surfaces of the upper box at positions facing the upper surface and side surfaces of the evaporator. If a bent duct that covers the top and sides of the evaporator is installed at a position that leads to the duct, even if the front surface of the dehumidifier is shielded by objects, air is sucked from the air inlets on the top and both sides. In addition to ensuring the performance of the dehumidifier, there is an effect that, even if foreign matter enters from the air suction ports on the upper surface and both side surfaces, it does not directly hit the side surface of the evaporator and the evaporator is not broken.
[0035]
