Description

本発明は、圧縮機と、圧縮機の脚部が防振装置を介して取り付けられる支持部材と、支持部材に固定されて圧縮機を側方と上方から覆う防音カバーとを備えた圧縮機ユニットに関するものである。   The present invention relates to a compressor unit including a compressor, a support member to which a leg portion of the compressor is attached via a vibration isolator, and a soundproof cover that is fixed to the support member and covers the compressor from the side and from above. It is about.

従来、例えば冷凍装置や空調装置の室外機には、冷媒回路で冷凍サイクルの圧縮行程を行う圧縮機が設けられている。この圧縮機は、室外機のケーシングのフレーム(支持部材)に、例えば防振ゴムを用いた防振装置を介して取り付けられている(例えば、特許文献1参照)。   Conventionally, for example, an outdoor unit of a refrigeration apparatus or an air conditioner is provided with a compressor that performs a compression stroke of a refrigeration cycle using a refrigerant circuit. This compressor is attached to the frame (support member) of the casing of the outdoor unit via a vibration isolator using, for example, a vibration isolator (see, for example, Patent Document 1).

特開2013−148236号公報JP 2013-148236 A

しかしながら、上記支持部材に対する圧縮機の取り付けに防振ゴムを用いた場合でも、圧縮機自体の振動は必ず生じるし、特許文献1の図6に記載されているように、圧縮機の上端部の横揺れの振動幅は比較的大きい。そのため、特許文献1の構成では、圧縮機に接続されている配管が大きく振動し、配管応力が過大になって配管が傷むような問題の発生が考えられる。   However, even when vibration-proof rubber is used to attach the compressor to the support member, the compressor itself always vibrates, and as shown in FIG. The vibration width of the roll is relatively large. For this reason, in the configuration of Patent Document 1, it is conceivable that the pipe connected to the compressor vibrates greatly and the pipe stress becomes excessive and the pipe is damaged.

特に、圧縮機を側方と上方から覆う防音カバーを室外機のケーシングのフレーム(支持部材)に取り付ける構成を採用する場合には、圧縮機が振動すると防音カバーに配管が繰り返し当たることになり、配管が傷みやすくなる。このように、従来の構成では、圧縮機と支持部材と防音カバーとからなる圧縮機ユニット(圧縮機取り付け構造部)において、配管が傷みやすくなる問題が生じることがあった。   In particular, when adopting a configuration in which a soundproof cover that covers the compressor from the side and from the top is adopted to the frame (support member) of the casing of the outdoor unit, when the compressor vibrates, the pipe repeatedly hits the soundproof cover, The piping is easily damaged. As described above, in the conventional configuration, there is a problem that the piping is easily damaged in the compressor unit (compressor mounting structure) including the compressor, the support member, and the soundproof cover.

本発明は、このような問題点に鑑みてなされたものであり、その目的は、防振装置を介して圧縮機を支持部材で支持し、かつ圧縮機を覆う防音カバーを支持部材に取り付けて構成される圧縮機ユニットにおいて、圧縮機の振動による配管の損傷を抑えることである。   The present invention has been made in view of such problems, and an object thereof is to support a compressor with a support member via a vibration isolator and attach a soundproof cover that covers the compressor to the support member. In the configured compressor unit, it is to suppress damage to the piping due to the vibration of the compressor.

第1の発明は、圧縮機(10)と、圧縮機(10)の脚部(20)が防振装置(25)を介して取り付けられる支持部材(30)と、該支持部材(30)に固定されて上記圧縮機(10)を側方と上方から覆う防音カバー(40)と、を備えた圧縮機ユニット(1)を前提としている。   The first invention includes a compressor (10), a support member (30) to which a leg (20) of the compressor (10) is attached via a vibration isolator (25), and the support member (30).

上記第1位置規制部材(50a)及び第2位置規制部材(50b)は、いずれもゴムなどの弾性体で形成されている。   The first position restricting member (50a) and the second position restricting member (50b) are both formed of an elastic body such as rubber.

この変形例によれば、圧縮機本体(10a)の吸入管(12)の変位量を第1位置規制部材(50a)で規制できるだけでなく、油分離器(10b)の吐出管(13)の変位量も第2位置規制部材(50b)で規制できる。   According to this modification, not only the displacement amount of the suction pipe (12) of the compressor body (10a) can be regulated by the first position regulating member (50a), but also the discharge pipe (13) of the oil separator (10b) can be regulated. The amount of displacement can also be regulated by the second position regulating member (50b).

そして、この変形例においても、図1の実施形態1と同様に、配管応力が過大になるのを抑えて配管が傷むのを抑えられるとともに、防振装置(25)に用いる防振ゴムの硬度を従来よりも下げることで運転時の振動減衰性能を高めることが可能になり、さらに、位置規制部材(50)を弾性体で形成することによる位置規制部材(50)の振動減衰効果で圧縮機(10)の振動や騒音を低減することも可能になる。   Also in this modified example, as in the first embodiment of FIG. 1, it is possible to suppress the piping stress from being excessively prevented from being damaged, and the hardness of the vibration isolating rubber used for the vibration isolating device (25).

《発明の実施形態2》
本発明の実施形態2について説明する。
<< Embodiment 2 of the Invention >>
A second embodiment of the present invention will be described.

図3は、この実施形態2の圧縮機ユニット(1)の断面構造図である。   FIG. 3 is a sectional structural view of the compressor unit (1) of the second embodiment.

この実施形態2では、位置規制部材(50)は、防音カバー(40)の天板(41)に設けられたブロック状の部材であり、輸送時に上記圧縮機(10)のケーシング(11)の上端部材(15)に接触し、静止時に上記ケーシング(11)の上端部材(15)から離れて位置するように構成されている。   In the second embodiment, the position regulating member (50) is a block-like member provided on the top plate (41) of the soundproof cover (40), and the casing (11) of the compressor (10) is transported during transportation. The upper end member (15) is in contact with the upper end member (15) and is positioned away from the upper end member (15) of the casing (11) when stationary.

この実施形態2において、圧縮機(10)のケーシング(11)の上端部材(15)は、図3に示しているように該圧縮機(10)のケーシング(11)の上端面を閉塞している部材である鏡板である。   In the second embodiment, the upper end member (15) of the casing (11) of the compressor (10) closes the upper end surface of the casing (11) of the compressor (10) as shown in FIG. It is the end plate which is a member.

この実施形態2では、図3において、位置規制部材(50)と圧縮機(10)の鏡板(15)との間の隙間は、吸入管(12)と防音カバー(40)の貫通孔(42)の内面との間の隙間よりも小さい。   In this Embodiment 2, in FIG. 3, the clearance gap between a position control member (50) and the end plate (15) of a compressor (10) is the through-hole (42 of a suction pipe (12) and a soundproof cover (40). ) Is smaller than the gap between the inner surface.

−作用−
この実施形態2では、圧縮機ユニット(1)を設置した後は支持部材(30)が静止する。したがって、この静止状態で圧縮機(10)を運転すると、該圧縮機(10)に運転時の振動が生じても、異常がなければ位置規制部材(50)と圧縮機(10)とは接触せず、圧縮機(10)の運転に影響は生じないし、防音カバー(40)の機能にも影響は生じない。
-Action-
In the second embodiment, the support member (30) is stationary after the compressor unit (1) is installed. Therefore, when the compressor (10) is operated in this stationary state, even if vibration occurs during operation of the compressor (10), the position regulating member (50) and the compressor (10) are in contact with each other if there is no abnormality. Therefore, the operation of the compressor (10) is not affected, and the function of the soundproof cover (40) is not affected.

一方、圧縮機ユニット(1)を輸送するときに、輸送の振動が大きくなると、圧縮機(10)の変位量が大きくなる上端部材の鏡板(15)が位置規制部材(50)に当接することにより、圧縮機(10)の動きを止めることができる。   On the other hand, when the compressor unit (1) is transported, if the transport vibration increases, the end plate (15) of the upper end member that increases the displacement of the compressor (10) comes into contact with the position restricting member (50). Thus, the movement of the compressor (10) can be stopped.

−実施形態2の効果−
この実施形態2によれば、輸送時の圧縮機(10)の振動を、動きが大きくなる上端部分の位置規制部材(50)で止めることができるから、配管応力が過大になるのを抑えることができ、ひいては配管が傷むのを抑えられる。特に、配管に比べて強度の高い圧縮機(10)のケーシング(11)と防音カバー(40)との間で変位量を規制しているので、位置規制を確実にすることができる。
-Effect of Embodiment 2-
According to the second embodiment, the vibration of the compressor (10) during transportation can be stopped by the position restricting member (50) at the upper end where the movement becomes large, so that the pipe stress is prevented from becoming excessive. Can be prevented and damage to the piping can be suppressed. In particular, since the amount of displacement is regulated between the casing (11) of the compressor (10) and the soundproof cover (40), which are stronger than the pipe, the position regulation can be ensured.

また、この実施形態2によれば、輸送時の振動を位置規制部材(50)で抑えられるから、防振装置(25)に用いる防振ゴムの硬度を従来よりも下げることができ、それによって、運転時の振動減衰性能を高めることが可能になる。   Further, according to the second embodiment, since vibration during transportation can be suppressed by the position regulating member (50), the hardness of the vibration isolating rubber used for the vibration isolating device (25) can be lowered as compared with the prior art, thereby It becomes possible to improve vibration damping performance during operation.
