Description

本発明はヒートポンプを備えた洗濯乾燥機に関する。   The present invention relates to a washing / drying machine equipped with a heat pump.

従来より、圧縮機、蒸発器及び凝縮器を有してなるヒートポンプを備えた洗濯乾燥機では、前記凝縮器で加熱した空気（温風）を水槽内に供給し、該水槽内及びその内部の回転槽を通して該回転槽内の衣類から水分を吸収し、その後該温風を前記蒸発器部分に戻して該蒸発器により冷却除湿し、再度前記凝縮器で加熱することを繰り返して乾燥を行うようにしている。   Conventionally, in a washing and drying machine equipped with a heat pump including a compressor, an evaporator, and a condenser, air (hot air) heated by the condenser is supplied into the water tank, and the water tank and the inside thereof are supplied. Moisture is absorbed from the clothes in the rotating tank through the rotating tank, and then the warm air is returned to the evaporator part, cooled and dehumidified by the evaporator, and heated by the condenser again to be dried. I have to.

また、この種の洗濯乾燥機では、回転槽を例えば４０〜６０ｒｐｍで低速回転させて洗い（すすぎも含む）運転を行い、また、６００〜１５００ｒｐｍで高速回転させて脱水運転を行うようにしており、また上記乾燥運転時には、回転槽を間欠的に正逆回転させるようにしている。   Further, in this type of washing and drying machine, for example, the rotating tub is rotated at a low speed of 40 to 60 rpm to perform washing (including rinsing), and the rotating tank is rotated at a high speed of 600 to 1500 rpm to perform a dehydrating operation. Also, during the drying operation, the rotating tank is intermittently rotated forward and reverse.

そして、前記圧縮機は、洗濯乾燥機が備えた設置ベースに弾性的に支持されており、この弾性支持構造が例えば特許文献１に示されている。この構造を、図６に示している。この図６において、圧縮機１の下部には取付板部２が取着されており、設置ベース３には、該取付板部２を支持することで前記圧縮機１を弾性支持する弾性脚４が配置されている。この弾性脚４は筒状をなしており、この弾性脚４の中空部４ａには、前記設置ベース３に立設された支柱部材としてのねじ５が挿通されている。   And the said compressor is elastically supported by the installation base with which the washing-drying machine was equipped, and this elastic support structure is shown by patent document 1, for example. This structure is shown in FIG. In FIG. 6, a mounting plate portion 2 is attached to the lower portion of the compressor 1, and an elastic leg 4 that elastically supports the compressor 1 by supporting the mounting plate portion 2 on the installation base 3. Is arranged. The elastic leg 4 has a cylindrical shape, and a screw 5 as a support member standing on the installation base 3 is inserted into the hollow portion 4 a of the elastic leg 4.

このねじ５の上部には例えばワッシャからなる上方への抜け止め部６が設けられている。この抜け止め部６により弾性脚４が上方へ抜けることが阻止されている。この場合、弾性脚４を抜け止め部６により押えてしまうと、弾性脚４が硬くなってしまって弾性支持に支障を来たすことから、抜け止め部６と弾性脚４との間には隙間Ｇが設けられている。
特開２００７−１４３７３６号公報 An upper retaining portion 6 made of a washer, for example, is provided on the upper portion of the screw 5. The stoppers 6 prevent the elastic legs 4 from being pulled upward. In this case, if the elastic leg 4 is pressed by the retaining portion 6, the elastic leg 4 becomes hard and hinders the elastic support. Therefore, there is a gap G between the retaining portion 6 and the elastic leg 4. Is provided.
JP 2007-143736 A

上記構成においては、乾燥運転時において圧縮機１が例えば２５〜１００Ｈｚで運転されるが、この乾燥運転時の圧縮機１の振動を吸収できるように弾性脚４が設けられているから、該圧縮機１の振動、及び該振動の設置ベース３側への伝播を抑制できる。しかし、回転槽が脱水時に回転駆動されると、洗濯機が１０〜２５Ｈｚで振動し、前記圧縮機１が共振して激しく揺れることがあった。特に、圧縮機１が上下方向に激しく揺れてしまい、圧縮機１と接続されている配管（冷媒配管）が破損するおそれがあった。   In the above configuration, the compressor 1 is operated at, for example, 25 to 100 Hz during the drying operation. Since the elastic legs 4 are provided so as to absorb the vibration of the compressor 1 during the drying operation, the compression is performed. The vibration of the machine 1 and the propagation of the vibration to the installation base 3 side can be suppressed. However, when the rotary tub is rotated during dehydration, the washing machine vibrates at 10 to 25 Hz, and the compressor 1 may resonate and shake vigorously. In particular, the compressor 1 may be vigorously shaken in the vertical direction, and there is a possibility that a pipe (refrigerant pipe) connected to the compressor 1 is damaged.

本発明は上記事情に鑑みてなされたものであり、その目的は、脱水運転時及び乾燥運転時のいずれにおいても圧縮機の振動を有効に緩和することができる洗濯乾燥機を提供することにある。   The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a washing / drying machine capable of effectively mitigating vibrations of the compressor in both the dehydrating operation and the drying operation. .

本発明は、次の点に着目してなされている。
すなわち、弾性脚上端と支柱部材の抜け止め部との間に隙間があると、脱水運転時の低周波数振動域において、圧縮機が規制されることなく隙間分激しく動くことが判った。この隙間部分を剛体のスペーサで埋めてしまうと、圧縮機運転時（乾燥運転時）に弾性脚の振動吸収作用が抑制されてしまう。 The present invention has been made paying attention to the following points.
That is, it has been found that if there is a gap between the upper end of the elastic leg and the retaining member of the column member, the compressor moves violently in the low frequency vibration region during the dehydration operation without being regulated. If this gap is filled with a rigid spacer, the vibration absorbing action of the elastic leg is suppressed during compressor operation (dry operation).

上述の事情を考慮して、本発明は、少なくとも洗い時及び脱水時に回転駆動される回転槽と、圧縮機、蒸発器及び凝縮器を有して構成され、前記回転槽内の衣類を乾燥させるためのヒートポンプと、前記圧縮機を設置するための設置ベースと、上下方向に開通する中空部を備えてほぼ筒状をなし前記設置ベースに上下方向に指向して配置され前記圧縮機を弾性支持する弾性脚と、前記設置ベースに前記弾性脚の中空部を挿通して立設する形態に取り付けられた支柱部材と、この支柱部材の上部に備えられた抜け止め部と、前記弾性脚上端と前記抜け止め部との間に隙間なく設けられ、前記弾性脚よりも柔弾性である構成の弾性部材とを備えたところに特徴を有する。   In view of the above-described circumstances, the present invention is configured to include a rotating tub that is rotationally driven at least during washing and dehydration, a compressor, an evaporator, and a condenser, and dries clothes in the rotating tub. A heat pump, an installation base for installing the compressor, and a hollow portion that opens in the up-down direction, is substantially cylindrical, and is arranged in the up-down direction and elastically supports the compressor An elastic leg, a column member attached to the installation base so as to stand through the hollow portion of the elastic leg, a retaining portion provided at an upper part of the column member, and an upper end of the elastic leg; It is characterized in that it is provided with an elastic member that is provided without a gap between the retaining portion and is more flexible than the elastic leg.

上記構成においては、圧縮機が運転される乾燥運転時には、弾性脚により圧縮機の振動を良好に吸収できると共に、該弾性脚よりも柔弾性である構成の弾性部材を該弾性脚上端と前記抜け止め部との間に隙間なく設けているから、脱水運転時に圧縮機が共振しても該圧縮機の動きが緩和される。   In the above-described configuration, during the drying operation in which the compressor is operated, the elastic leg can absorb the vibration of the compressor well, and the elastic member having a configuration that is more elastic than the elastic leg is removed from the upper end of the elastic leg and the omission. Since there is no gap between the stopper and the stopper, the movement of the compressor is alleviated even if the compressor resonates during the dehydrating operation.

本発明によれば、脱水運転時及び乾燥運転時のいずれにおいても圧縮機の振動を良好に低減できる。   According to the present invention, the vibration of the compressor can be satisfactorily reduced both during the dehydration operation and during the drying operation.

The supporting form is a horizontal axis in which the axial direction of the water tank 24 is front and rear, and Therefore, the drum 25 has the same shape.

筐体２１の台板２２には、ヒートポンプ４０が配設されている。このヒートポンプ４０は、台板２２に脚体４７により弾性的に支持された支持板４１上に、圧縮機４２、蒸発器４３及び凝縮器４４、さらには送風装置４５を配設した一体構造であり、上記蒸発器４３、凝縮器４４、送風装置４５の送風羽根４５ａはヒートポンプ用ダクト４６により形成された通風路内に位置する。なお、前記送風装置４５は前記送風羽根４５ａと送風モータ４５ｂとから構成されている。   A heat pump 40 is disposed on the base plate 22 of the housing 21. The heat pump 40 has an integrated structure in which a compressor 42, an evaporator 43 and a condenser 44, and a blower 45 are disposed on a support plate 41 elastically supported on a base plate 22 by legs 47. The evaporator 43, the condenser 44, and the blower blade 45 a of the blower 45 are located in the ventilation path formed by the heat pump duct 46. In addition, the said air blower 45 is comprised from the said ventilation blade 45a and the ventilation motor 45b.

前記ヒートポンプ４０のヒートポンプ用ダクト４６の前端部４６ａは温風戻しダクト４８の一端部に接続されている。この温風戻しダクト４８はほぼＬ字状をなしており、この温風戻しダクト４８の他端部である垂直状部分の上端部は、排気ダクト４９を介して前記排気口３１に接続されている。前記排気ダクト４９における前記温風戻しダクト４８近傍には、蛇腹部４９ａが設けられている。   A front end 46 a of the heat pump duct 46 of the heat pump 40 is connected to one end of the warm air return duct 48.

前記前記筐体２１の前面部２１ａにリントフィルタ５２が取り出し可能に挿入配置されており、このリントフィルタ５２は前記温風戻しダクト４８内を流通する温風中からリントを捕獲するものである。   A lint filter 52 is removably inserted into the front surface 21 a of the casing 21, and the lint filter 52 captures lint from the warm air flowing through the warm air return duct 48.

さて、前記圧縮機４２は、例えば３箇所で、前記支持板４１（設置ベース）に弾性支持装置５３により弾性支持されている。この弾性支持装置５３について説明する。この弾性支持装置５３は、取付板部５４、支柱部材たるねじ５５、弾性脚５６、弾性部材５７、抜け止め部たるナット５８を備えて構成されている。前記取付板部５４は前記圧縮機４２に水平状態に取り付けられている。この取付板部５４には、平面的にみて圧縮機４２の軸心周りに３つの嵌合孔５４ａ（一つのみ図示）を均等配置状態に形成されている。   The compressor 42 is elastically supported by the elastic support device 53 on the support plate 41 (installation base) at, for example, three locations. The elastic support device 53 will be described. The elastic support device 53 includes a mounting plate portion 54, a screw 55 as a support member, an elastic leg 56, an elastic member 57, and a nut 58 as a retaining portion. The attachment plate portion 54 is attached to the compressor 42 in a horizontal state. In the mounting plate portion 54, three fitting holes 54a (only one is shown) are formed in an evenly arranged state around the axis of the compressor 42 in a plan view.

前記ねじ５５は支柱部材たるものであり、前記支持板４１に前記嵌合孔５４ａと対応するように３箇所に立設されている。すなわち、このねじ５５は下端部に頭部５５ａを有し、この頭部５５ａの上部に円柱状の柱部５５ｂを有し、この柱部５５ｂの上部には該柱部５５ｂより小径な雄ねじ部５５ｃを有する。前記柱部５５ｂ上端には水平な平坦面からなる受け部５５ｄが形成されている。
このねじ５５は、前記支持板４１の３箇所に形成されたねじ挿通孔部４１ａ（一つのみ図示）に下方から挿通されて頭部５５ａが支持板４１に例えば溶接により固定されており、もって、該ねじ５５は、支持板４１に上下方向に指向して立設されている。 The screws 55 are column members, and are erected at three positions on the support plate 41 so as to correspond to the fitting holes 54a. That is, the screw 55 has a head portion 55a at the lower end, a columnar column portion 55b at the upper portion of the head portion 55a, and a male screw portion having a smaller diameter than the column portion 55b at the upper portion of the column portion 55b. 55c. A receiving portion 55d having a horizontal flat surface is formed at the upper end of the column portion 55b.
The screws 55 are inserted from below into screw insertion holes 41a (only one shown) formed at three locations on the support plate 41, and the head portion 55a is fixed to the support plate 41 by welding, for example. The screw 55 is erected on the support plate 41 in the vertical direction.

前記弾性脚５６は、例えばゴムから構成されており、上下方向に開通する中空部５６ａを備えてほぼ筒状をなしている。該弾性脚５６の周壁部は縦断面形状が厚肉な蛇腹状をなし、上部外周部に係合凹溝部５６ｂが形成されている。なお、この弾性脚５６の上端部は平坦面５６ｃとなっている。またこの弾性脚５６の高さ寸法は、前記ねじ５５の柱部５５ｂの高さより若干高くなっている。この弾性脚５６により圧縮機４２は共振周波数がほぼ２０Ｈｚ程度となるように支持されている。   The elastic leg 56 is made of rubber, for example, and has a hollow portion 56a that opens in the vertical direction, and has a substantially cylindrical shape. The peripheral wall portion of the elastic leg 56 has a bellows shape with a thick vertical cross-section, and an engaging groove portion 56b is formed in the upper outer peripheral portion. The upper end portion of the elastic leg 56 is a flat surface 56c. The height of the elastic leg 56 is slightly higher than the height of the column 55b of the screw 55. The elastic leg 56 supports the compressor 42 so that the resonance frequency is about 20 Hz.

前記弾性部材５７は、発泡材質例えばＥＰＤＭ（エチレンプロピレンジエンゴム）製のスポンジから構成され、もって、前記弾性脚５６より柔らかい弾性である構成である。この弾性部材５７は円形板状をなしており、中心部に挿通孔５７ａを有する。この場合、この弾性部材５７の挿通孔５７ａの直径寸法は、前記弾性脚５６の平坦面５６ｃの内周部の直径寸法より小さく、該弾性部材５７ａの外径寸法は、前記弾性脚５６の平坦面５６ｃの外径より大きくなるように設定されている。   The elastic member 57 is made of a foam material, for example, a sponge made of EPDM (ethylene propylene diene rubber), and thus has a softer elasticity than the elastic legs 56. The elastic member 57 has a circular plate shape and has an insertion hole 57a at the center. In this case, the diameter dimension of the insertion hole 57 a of the elastic member 57 is smaller than the diameter dimension of the inner peripheral portion of the flat surface 56 c of the elastic leg 56, and the outer diameter dimension of the elastic member 57 a is flat of the elastic leg 56. It is set to be larger than the outer diameter of the surface 56c.

前記ナット５８は座金５８ａを一体に有する座金付ナットから構成されている。
前記弾性支持装置５３の組み立て手順について説明する。前記弾性脚５６の係合凹溝部５６ｂを前記取付板部５４の嵌合孔５４ａに嵌合しておき、この弾性脚５６を、前記支持板４１に立設した前記ねじ５５に上方から嵌合し、弾性部材５７をねじ５５の雄ねじ部５５ｃに嵌合させて弾性脚５６の平坦面５６ｃに配置し、ナット５８を該雄ねじ部５５ｃにねじ込む。この場合、ナット５８は、弾性脚５６の上端である平坦面５６ｃと該ナット５８との間に隙間がないように締めている。この結果、前記弾性部材５７は前記弾性脚５６上端と前記ねじ５５の上部の抜け止め部であるナット５８との間に隙間なく設けられている。 The nut 58 is constituted by a nut with a washer integrally having a washer 58a.
A procedure for assembling the elastic support device 53 will be described. The engaging groove portion 56b of the elastic leg 56 is fitted into the fitting hole 54a of the mounting plate portion 54, and the elastic leg 56 is fitted to the screw 55 erected on the support plate 41 from above. Then, the elastic member 57 is fitted into the male screw portion 55c of the screw 55 and disposed on the flat surface 56c of the elastic leg 56, and the nut 58 is screwed into the male screw portion 55c. In this case, the nut 58 is tightened so that there is no gap between the flat surface 56 c that is the upper end of the elastic leg 56 and the nut 58. As a result, the elastic member 57 is provided without a gap between the upper end of the elastic leg 56 and the nut 58 which is a retaining portion at the top of the screw 55.

上記弾性脚５６は、前述した蛇腹形状の中空筒状としていることで、圧縮機４２の共振周波数をほぼ２０Ｈｚとなるようにしている。
さて、上記構成において、洗い運転時及びすすぎ運転時には前述したように、ドラム２５が４０〜６０ｒｐｍで低速回転駆動され、その場合、圧縮機４２の振動数は０．７〜１０Ｈｚぐらいである。また、脱水運転時には、ドラム２５が６００〜１５００ｒｐｍで高速回転駆動され、その場合、圧縮機４２に作用する振動数は１０〜２５Ｈｚぐらいである。 The elastic leg 56 has the above-described bellows-shaped hollow cylindrical shape so that the resonance frequency of the compressor 42 is approximately 20 Hz.
Now, in the above configuration, as described above during the washing operation and the rinsing operation, the drum 25 is driven to rotate at a low speed of 40 to 60 rpm. In this case, the frequency of the compressor 42 is about 0.7 to 10 Hz. Further, during the dehydration operation, the drum 25 is driven to rotate at a high speed of 600 to 1500 rpm. In this case, the frequency acting on the compressor 42 is about 10 to 25 Hz.

乾燥運転時には、ドラム２５が回転されると共に、送風装置４５が運転され、さらに圧縮機４２が運転される。該圧縮機４２が運転されると、圧縮機４２内の冷媒が圧縮されて吐出され、凝縮器４４で放熱し、蒸発器４３で蒸発する。そして、送風装置４５が運転されることにより、温風循環路５１を図１の矢印で示すように循環する。このとき、循環空気が前記凝縮器４４で加熱されて、水槽２４内（ドラム２５内）に供給され、この際にドラム２５内の洗濯物の乾燥に寄与し、水槽２４の排気口３１から出て、前記蒸発器４３により冷却除湿され、再度前記凝縮器４４で加熱されることが繰り返えされる。   During the drying operation, the drum 25 is rotated, the air blower 45 is operated, and the compressor 42 is further operated. When the compressor 42 is operated, the refrigerant in the compressor 42 is compressed and discharged, dissipates heat in the condenser 44, and evaporates in the evaporator 43. And by operating the air blower 45, it circulates through the warm air circulation path 51 as shown by the arrow in FIG. At this time, the circulating air is heated by the condenser 44 and supplied into the water tank 24 (in the drum 25). At this time, it contributes to the drying of the laundry in the drum 25 and is discharged from the exhaust port 31 of the water tank 24. Then, it is repeatedly cooled and dehumidified by the evaporator 43 and heated by the condenser 44 again.

この場合、圧縮機４２は、冷媒としてＲ４１０Ａを使用する場合には、２５〜６０Ｈｚ程度で運転され、また冷媒としてＲ１３４ａを使用する場合には、４０〜１００Ｈｚ程度で運転される。つまり、圧縮機４２の運転周波数は２５〜１００Ｈｚである。   In this case, the compressor 42 is operated at about 25 to 60 Hz when R410A is used as the refrigerant, and is operated at about 40 to 100 Hz when R134a is used as the refrigerant. That is, the operating frequency of the compressor 42 is 25 to 100 Hz.

さて、上記構成の本実施例において、圧縮機４２が運転される乾燥運転時には、その振動は小さいため、従来設けられていた隙間を弾性部材５７が埋めていてもその影響は無視できることから、弾性脚５６により圧縮機４２は共振状態となることがなく圧縮機４２の振動が良好に吸収される。また、該弾性脚５６よりも柔弾性である構成の弾性部材５７を該弾性脚５６上端と前記ナット５８との間に隙間なく設けているから、脱水運転時にその回転上昇に伴い圧縮機４２が共振しても該圧縮機４２の動きが、弾性部材５７が変形することにより緩和される。この結果、本実施例によれば、脱水運転時及び乾燥運転時のいずれにおいても圧縮機４２の振動を良好に低減できる。さらには、据付時などに過大な衝撃が加わっても圧縮機４２の急激な動きを弾性部材５７が緩和するため、デリケートな冷媒配管の破損などを未然に防止することができる。   In the present embodiment having the above-described configuration, since the vibration is small during the drying operation in which the compressor 42 is operated, even if the conventionally provided gap is filled with the elastic member 57, the influence can be ignored. The leg 56 prevents the compressor 42 from being in a resonance state and absorbs the vibration of the compressor 42 well. Further, since the elastic member 57 having a configuration that is more flexible than the elastic leg 56 is provided between the upper end of the elastic leg 56 and the nut 58, there is no gap between the compressor 42 and the rotation of the compressor 42 during the dehydrating operation. Even if the resonance occurs, the movement of the compressor 42 is alleviated by the deformation of the elastic member 57. As a result, according to the present embodiment, it is possible to satisfactorily reduce the vibration of the compressor 42 during both the dehydrating operation and the drying operation. Furthermore, even if an excessive impact is applied during installation or the like, the elastic member 57 moderates the rapid movement of the compressor 42, so that it is possible to prevent the delicate refrigerant piping from being damaged.

図３は本発明の第２の実施例を示しており、弾性部材６１は、弾性脚５６側からナット５８側に向かって断面積が増加する形状に形成されており、この場合ほぼ逆円錐状に形成された点が第１の実施例と異なる。   FIG. 3 shows a second embodiment of the present invention, wherein the elastic member 61 is formed in a shape whose cross-sectional area increases from the elastic leg 56 side toward the nut 58 side. This is different from the first embodiment.

この第２の実施例によれば、圧縮機４２の振動振幅（上下振動振幅）が少ない洗い運転時などにおいては、その振動が断面積の小さくて柔らかい弾性部材５７下部に作用するから、弾性脚５６の制振効果を妨げることがなく、そして脱水運転時などにおいて、圧縮機４２の振動振幅（上下振動振幅）が大きくなるほど、該弾性部材５７自体の制振効果が大きくなり、総じて、洗い運転時においては弾性脚５６の制振作用を良好に発揮させ、且つ脱水運転時には弾性部材６１の制振作用を良好に発揮させることができる。   According to the second embodiment, during a washing operation where the vibration amplitude (vertical vibration amplitude) of the compressor 42 is small, the vibration acts on the lower portion of the soft elastic member 57 having a small cross-sectional area. 56. The vibration damping effect of the elastic member 57 itself increases as the vibration amplitude (vertical vibration amplitude) of the compressor 42 increases during the dehydrating operation, and the washing operation is generally performed. In some cases, the vibration damping action of the elastic leg 56 can be satisfactorily exhibited, and the vibration damping action of the elastic member 61 can be favorably exhibited during the dehydrating operation.

図４は本発明の第３の実施例を示しており、弾性部材７１の構成が第１及び第２の実施例と異なる。すなわち、弾性部材７１は、平板部７１ａと該平板部７１ａの周縁部から立ち下がる周壁部７１ｂとを有した構成である。この第３の実施例においても、前記第２の実施例とほぼ同様の効果を奏する。   FIG. 4 shows a third embodiment of the present invention, and the configuration of the elastic member 71 is different from those of the first and second embodiments. That is, the elastic member 71 includes a flat plate portion 71a and a peripheral wall portion 71b that falls from the peripheral portion of the flat plate portion 71a. This third embodiment also has substantially the same effect as the second embodiment.

図５は本発明の第４の実施例を示しており、弾性部材８１の構成が第１及び第２の実施例と異なる。すなわち、弾性部材８１は、弾性度合いが異なる複数の単一部材８１ａ、８１ｂを積層して構成されている。この場合、単一部材８１ａの弾性度合いが単一部材８１ｂの弾性度合いより柔らかく構成されている。そして柔らかいほうの単一部材８１ａが下側で、別の単一部材８１ｂが上側となるように、つまり、柔らかいものから硬くなるものの順に、弾性脚５６側からナット５８側となるように積層して構成されている。   FIG. 5 shows a fourth embodiment of the present invention, and the configuration of the elastic member 81 is different from those of the first and second embodiments. That is, the elastic member 81 is configured by laminating a plurality of single members 81a and 81b having different degrees of elasticity. In this case, the elasticity of the single member 81a is configured to be softer than the elasticity of the single member 81b. Then, the soft single member 81a is on the lower side and the other single member 81b is on the upper side, that is, in order from the softer one to the harder one is laminated so that the elastic leg 56 side becomes the nut 58 side. Configured.

この第４の実施例においても、第２の実施例と同様の効果を奏する。
なお、上記実施例では、抜け止め部として座金付ナットを例示したが、ナットと座金とは別部材でもよく、この場合、座金が抜け止め部として作用する。また、設置ベースにねじ孔を形成し、支柱部材としてのねじを該設置ベースに上からねじ込むことによりねじを立設する構成としても良い。また、弾性部材は粘弾性体から構成しても良い。この粘弾性体としては、株式会社ジェルテックの「αGEL」（アルファゲル（登録商標））などが知られている。このようにすると、脱水運転時における圧縮機４２の振動をさらに緩和できる。 In the fourth embodiment, the same effects as in the second embodiment can be obtained.
In the above embodiment, the nut with washer is illustrated as the retaining portion, but the nut and the washer may be separate members. In this case, the washer functions as the retaining portion. Alternatively, a screw hole may be formed in the installation base, and a screw may be erected by screwing a screw as a support member into the installation base from above. The elastic member may be composed of a viscoelastic body. As this viscoelastic body, “αGEL” (Alphagel (registered trademark)) manufactured by Geltech Co., Ltd. is known. If it does in this way, vibration of compressor 42 at the time of dehydration operation can further be eased.
