Description

[Detailed description of the invention] (a) Industrial application field The present invention relates to a refrigerator unit, and particularly relates to a refrigerator unit equipped with a compressor whose rotation speed is controlled by an inverter.

(b) Conventional technology Conventionally, this type of refrigerator unit was
It was described in the specification of No. 33185 and was constructed as shown in FIG. To explain below, 31 is a compressor 32 whose rotation speed is controlled by an inverter, a condenser 33, a liquid receiver 34, an expansion valve 35, and an evaporator 36.
This refrigerator unit is equipped with an electrical equipment box 37 that houses an inverter control panel and the like for the compressor 32. This unit has floor 3
A metal fitting 40 fixed to 8 with an anchor bolt 39,
The liquid receiver 34 and the electrical equipment box 37 are fixed to the floor via 40, and a vibration isolating rubber 41 is attached to the upper part of the liquid receiver 34.
While fixing the compressor 32 via the liquid receiver 34
The liquid receiver and the electrical equipment box 37 were connected by a metal fitting 42 fixed to one side of the liquid receiver.

(c) Problems to be solved by the invention However, according to the above configuration, the compressor 32
vibration-proof rubber 41 interposed between and the liquid receiver 34
The reason is that hard rubber is used to prevent the compressor from causing resonance even when the compressor 32 is operated in a low rotational speed range, and that the liquid receiver 34 and the electrical equipment box 3 are made of hard rubber.
Since it is connected by the metal fitting 42 with 7,
The vibration of the compressor 32 is transmitted to the electrical equipment box 3 via the liquid receiver 34.
There was a problem in that the electrical equipment box vibrated easily and the internal inverter control parts were damaged.

Here, in the case of a refrigerator unit having the above configuration, in order to reduce the vibration of the electrical equipment box 37, it is sufficient to install the electrical equipment box separately from the main body of the unit. Since the refrigerator unit is no longer an integrated unit, the unit main body and the electrical box 37 must be packed and transported separately, and the wiring and piping between the equipment in the unit main body and the parts in the electrical box 37 must be handled separately. This method is impractical because of problems such as having to do this on-site and adjusting the control equipment of the electrical box 37 on-site.

This proposal was developed in view of the above, and is aimed at improving on-site wiring, piping, and transportation between the equipment in the unit itself and the parts in the electrical box in a refrigerator unit equipped with a compressor whose rotation speed is controlled by an inverter. The purpose is to reduce the vibration transmitted from the compressor to the electrical box by making it possible to easily separate the unit main body and the electrical box on-site without the need for separate packaging of the unit main body and the electrical box. shall be.

(d) Means for solving the problem This proposal consists of a unit body consisting of a liquid receiver and a refrigerant compressor fixed to the upper part of the liquid receiver, an electrical box containing control parts for the compressor, and In a refrigerator unit in which the electrical equipment box is connected and integrated via a mount to which the electrical equipment box is fixed, the mount is a base on which the electrical equipment box is mounted and a support to which the metal fitting of the liquid receiver is fixed. The electrical equipment box is fixed to the base of the mount via a vibration isolator, and the wall of the electrical equipment box is fixed to the base of the mount via a vibration isolator. The unit is fixed to a column, and the width of the column in the direction in which the unit body and the electrical box are lined up is set to such a width that the unit body and the electrical box do not come into contact even when the unit is shaken at its maximum during transportation or the like.

(E) Effect The refrigerating machine unit of the present invention has a column and a base that have a wide width in the direction in which the unit body and the electrical equipment box are lined up, and a connecting means such as a bolt that connects the column and the metal fitting of the liquid receiver. Even if the electrical box is removed, the electrical box can be left standing in a stable state, and when installing the unit, the unit body and the electrical box can be easily separated by simply removing the connecting means, and the transmission from the compressor to the electrical box can be easily separated. Vibration can be reduced. As well,
The pillars of the pedestal frame have sufficient dimensions to prevent contact between the electrical box and the unit body even during shaking during transportation, so the vibration isolating device interposed between the pedestal and the electrical box This makes it possible to use springs with as low a spring constant as possible, thereby making it possible to reduce vibrations transmitted from the compressor to the electrical box even if the unit body and electrical box are installed as one unit.

Here, the width of the steel members 19 and 20 serving as the supports in the direction in which the unit main body 1a and the electrical equipment box 9 are arranged is such that even when the unit is shaken at its maximum width during transport, the unit main body 1a and the electrical equipment box 9 do not touch each other. It is formed to a width that is not wide. The vibration isolating rubber 1 interposed between the compressor 2 and the liquid receiver 4 is placed on the steel materials 17 and 18 that serve as the base of this frame.
The electrical equipment box 9 is fixed via a vibration isolating rubber 22 that is softer than that of the electrical equipment box 9. Further, the side wall of this electrical equipment box 9 is made of soft vibration-proof rubber 2 similar to the vibration-proof rubber 22.
Bolts 2 are attached to the steel materials 19 and 20 that become the supports through 3.
