Description

Technical Field

[0001] The invention relates to a supporting structure of a compressor. Background Art

[0002] A compressor equipped in an air conditioner or the like includes a support structure having a vibration-proof function. Conventionally, as a support structure of a compressor, when the compressor body is fixed to a table, a leg portion protrudes from the compressor body in three directions on a horizontal plane, and the leg portion is fixed to the table via an elastic member by bolts or the like (see Patent Document 1 below). Prior art literature Patent Literature

[0003] Patent Document 1: Japanese Patent Application Publication No. 2002-70777 Summary of the invention Technical problem to be solved by the invention

[0004] The supporting structure in the conventional compressor is a structure in which the lower end side of the compressor body in the vertical direction is fixedly supported on the table plate, and vibration and noise prevention are achieved by sandwiching elastic members. However, according to this supporting structure, since the upper end side of the compressor body in the vertical direction is a free end, the vibration of the upper end side of the compressor body cannot be effectively suppressed. In particular, in a vertical compressor in which the center of gravity of the compressor body is far from the support portion supporting the table plate, the vibration of the upper end side of the compressor body becomes more significant in structure.

[0005] In this way, if vibration occurs on the upper end side of the compressor body, a load is applied to the refrigerant piping connected to the compressor body in the air conditioning device including the compressor body. If the load causes damage or detachment at the connection portion of the refrigerant piping, etc., the refrigerant circuit may malfunction. Therefore, in the air conditioning device, it is desirable to suppress the vibration of the compressor body and operate the refrigerant circuit stably.

[0006] In addition, sometimes a power connector is connected to the upper end of the compressor body. In this case, if vibration is generated on the upper end side of the compressor body, the power connector may fall off due to the vibration.

[0007] The present invention is proposed to cope with such a situation, and its object is to effectively suppress vibration of the upper end side of the compressor body and to suppress the detachment of the power connector connected to the upper end of the compressor body in the support structure of the compressor. Technical solutions adopted to solve technical problems

[0008] In order to solve such technical problems, a support structure for a compressor according to the present invention includes the following structure. A support structure for a compressor, which supports the compressor by fixing a leg portion provided on a compressor body to a table plate via an elastic member, wherein a power connector is connected to the upper portion of the compressor body, a cover member covering the power connector is installed in the compressor body, and the cover member is fixed by fixing the leg portion to the table plate via a fixing member. Effects of the Invention

[0009] The support structure of the compressor of the present invention having such features can effectively suppress the vibration of the upper end side of the compressor body, and can suppress the detachment of the power connector connected to the upper end of the compressor body. As a result, the refrigerant circuit including the compressor body can be stably operated, and the air conditioner having the refrigerant circuit capable of stable operation can be operated smoothly and quietly.

DETAILED DESCRIPTION

[0011] Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. In the following description, the same reference numerals in different drawings represent parts with the same functions, and repeated descriptions in the drawings will be appropriately omitted.

[0012] like Figure 1 and Figure 2As shown, in the support structure 1 of the compressor according to the embodiment of the present invention, the compressor body 10 has a leg 11 for fixing itself to the table 100. A plurality of legs 11 protrude at equal intervals on a horizontal plane (in the example shown in the figure, protrude at equal intervals in three directions), and an elastic member 12 such as a rubber member or a spring member is interposed between the leg 11 and the table 100.

[0013] A power connector 20 is connected to the upper end of the compressor body 10 . The power connector 20 is provided at the end of a power cable 21 connected to a power source (not shown) at one end and is connected to a connection terminal 13 provided at the upper end of the compressor body 10 .

[0014] In order to cover the power connector 20, a cover member 30 is installed on the upper part of the compressor body 10. The cover member 30 has a hole 31 for the pipe (refrigerant pipe) 14 connected to the compressor body 10 to pass through, and has a hole 32 for the power cable 21 to pass through. The cover member 30 has a fixing piece 33 for fixing itself, and the cover member 30 is fixed to the base plate 100 through the fixing member 40 that fixes the leg portion 11 of the compressor body 10 to the base plate 100 via the fixing piece 33.

[0015] exist Figure 1 and Figure 2 In the example shown, the fixing member 40 includes a long bolt 41 extending in the vertical direction, a nut 42 screwed with the bolt 41, and a collar 43 through which the bolt 41 is inserted. In the illustrated support structure 1, the head of the bolt 41 is embedded in the support or fixed in the table 100, the front end of the bolt 41 faces upward, and the threaded portion is vertically arranged relative to the table 100. In contrast, an elastic member 12 is sandwiched between the table 100 and the leg 11 of the compressor body 10, and a collar 43 is sandwiched between the leg 11 and the fixing plate 33, and the nut 42 is screwed into the threaded portion of the bolt 41 coaxially inserted relative to the leg 11 and the fixing plate 33 from above the fixing plate 33. Thus, the fixing member 40 fixes the leg 11 and the fixing plate 33 coaxially.

[0016] At this time, a well-known anti-loosening function can be added by interposing a washer or a spring washer (not shown) with respect to the nut 42 or adopting a double nut.

[0017] Thus, the lower portion of the compressor body 10 is fixed to the fixing member 40 via its own leg portion 11, and the upper portion of the compressor body 10 is fixed to the fixing member 40 via the fixing piece 33 of the cover member 30. Thus, since the lower portion and the upper portion of the compressor body 10 are fixed to the base plate 100 by a plurality of fixing members 40, vibration of the upper end side of the compressor body 10 can be effectively suppressed.

[0018] In addition, since the cover member 30 is fixed to the upper part of the compressor body 10 in a manner that covers the power connector 20 connected to the upper end of the compressor body 10, the power connector 20 is always pressed against the compressor body 10, which can effectively prevent the power connector 20 from falling off.

[0019] Here, the cover member 30 is fixedly mounted on the upper portion of the compressor body 10 , but in practice, by sandwiching a cushioning member such as sponge inside the cover member 30 , shaking and impact sound between the compressor body 10 and the cover member 30 can be suppressed.

[0020] Moreover, in such a support structure 1, if the fixed position of the cover member 30 (the position of the fixing plate 33) is set near the height position of the center of gravity G of the compressor body 10, the vibration of the compressor body 10 can be more effectively suppressed, and the power connector 20 can be effectively suppressed from falling off.

[0021] Figure 3 The example shown is Figure 1 and Figure 2 In the modified example shown, the pipe 14 connected to the compressor body 10 extends laterally. In this case, as shown in the figure, the cover member 30 is provided with a cutout portion 34 instead of the hole portion 31, so that the pipe 14 can be led out. In addition, the power cable 21 can also be led out through the same cutout portion.

[0022] Figure 4 The example shown is a modification of the above example. In this example, a threaded structure (internal thread) is provided on the fixing plate 33 of the cover member 30, and the bolt 41 is directly screwed into it, thereby omitting the nut 42. In this case, the fixing plate 33 has a thickness t for effectively providing the internal thread. Figure 5 The example shown is also a modified example of the above example. In this example, the collar 43 can be omitted by fixing the leg 11 with the nut 42. In this case, as described above, a well-known anti-loosening function can be added by sandwiching a washer or a spring washer (not shown) with respect to the nut 42 or using a double nut.

[0024] Figure 6 and Figure 7An air conditioner 101 including the support structure of the compressor is shown. The air conditioner 101 is provided with a heater (condenser) 110, a cooler (evaporator) 130, and a pressure reducer 150 in addition to the compressor body 10 to form a refrigerant circuit, a first blower 140 is provided for the cooler 130, and a second blower 120 is provided for the heater 110. In addition, a control device 160 for controlling the compressor body 10 and the blowers (the first blower 140 and the second blower 120) is included.

[0025] In the frame of the air-conditioning device 101 which is omitted from the figure, a compressor body 10, a heater (condenser) 110 and a second blower 120 are arranged on the table 100, and a cooler (evaporator) 130, a first blower 140, a pressure reducer 150 and a control device 160 are arranged on the upper side in the vertical direction thereof, thereby making the air-conditioning device 101 a compact and portable small unit.

[0026] In order to form such a compact structure, the pressure reducer 150 is arranged on one side (left side when viewed from the front) of the cooler 130 in a direction perpendicular to the flow direction of air passing through the cooler 130 and in the horizontal direction of the cooler 130 (left-right direction when viewed from the front), and the compressor body 10 is arranged on the other side (right side when viewed from the front) of the cooler 130 and on the vertically lower side of the cooler 130. In addition, the control device 160 is arranged on the other side of the cooler 130 (upper side in the vertical direction of the compressor body 10). In addition, the storage tank 111 is arranged in front of the compressor body 10.

[0027] Furthermore, on the platen 100, when viewed from the front, the compressor body 10 is arranged on the right side of the heater 110, and the second blower 120 is arranged on the front side of the heater 110. The cooler 130 is arranged vertically above the heater 110 and slightly in front of the heater 110 so as to partially overlap the heater 110 in the vertical direction. When viewed from the front, the pressure reducer 150 is arranged on the left side of the cooler 130, the control device 160 is arranged on the right side, and the first blower 140 is arranged on the back side of the cooler 130.

[0028] In addition, on the upper surface of the cooler 130, on one side of the cooler 130 (the left side when viewed from the front), that is, on the side of the pressure reducer 150, a refrigerant inlet 131 is provided for allowing the refrigerant after passing through the pressure reducer 150 to flow into the cooler 130. In addition, on the upper surface of the cooler 130, at a position further to the rear side than the refrigerant inlet 131, a refrigerant outlet 132 for the refrigerant that passes through the cooler 130 and returns to the compressor body 10 is provided.

[0029] That is, in the cooler 130, the refrigerant inlet 131 is provided so that the refrigerant flows in from the upper surface of the cooler 130, and the refrigerant outlet 132 is provided so that the refrigerant flows out from the upper surface of the cooler 130. The refrigerant outlet 132 and the compressor body 10 are connected by the refrigerant pipe 94. The refrigerant pipe 94 is drawn from the refrigerant outlet 132 to the back side of the control device 160, passes through the lower side of the control device 160, and is connected to the front side of the compressor body 10.

[0030] A refrigerant inlet 112 is provided on the upper surface of the heater 110, on one side (left side when viewed from the front) of the heater 110 and on the rear side of the heater 110, into which the high-pressure refrigerant discharged from the compressor body 10 flows. In addition, a refrigerant outflow port 113 is provided on the upper surface of the heater 110, which passes through the heater 110 and flows out toward the pressure reducer 150, on the front side of the refrigerant inlet 112.

[0031] That is, in the heater 110, the refrigerant inlet 112 is provided so that the refrigerant flows in from the upper surface of the heater 110, and the refrigerant outlet 113 is provided so that the refrigerant flows out from the upper surface of the heater 110. The compressor body 10 is connected to the refrigerant inlet 112 of the heater 110 through the refrigerant pipe 91, the refrigerant outlet 113 is connected to the pressure reducer 150 through the refrigerant pipe 92, and the pressure reducer 150 is connected to the refrigerant inlet 131 of the cooler 130 through the refrigerant pipe 93. Both the refrigerant pipe 92 and the refrigerant pipe 93 are located on the pressure reducer 150 side relative to the cooler 130. In such an air-conditioning device 101, the refrigerant is compressed by the compressor body 10 to become a high-pressure gas refrigerant and is discharged. The high-pressure gas refrigerant passes through the refrigerant piping 91 and flows into the heater 110 via the refrigerant inlet 112, and dissipates heat by exchanging heat with the air supplied from the second blower 120 and passing through the heater 110.

[0033] The high-pressure refrigerant flowing out of the refrigerant outlet 113 of the heater 110 passes through the refrigerant pipe 92 and flows into the pressure reducer 150, is reduced in pressure by the pressure reducer 150 and expands to become a low-pressure refrigerant. The refrigerant that has become low-pressure in the pressure reducer 150 passes through the refrigerant pipe 93 and flows into the cooler 130 from the refrigerant inlet 131. The low-pressure refrigerant flowing into the cooler 130 absorbs heat by heat exchange with the air blown by the first blower 140 and passing through the cooler 130, and flows out through the refrigerant outlet 132 of the cooler 130. The refrigerant flowing out of the cooler 130 flows through the refrigerant pipe 94, and returns to the compressor body 10 through the accumulator 111. The refrigerant flowing into the compressor body 10 is compressed again, and the above cycle is repeated.

[0034] In contrast, the first blower 140 is disposed on the upstream side of the air flow direction of the cooler 130, and blows air sucked from an inlet provided on the back of a housing (not shown) to the cooler 130. The air blown from the first blower 140 to the cooler 130 is cooled by the refrigerant absorbing heat while passing through the cooler 130. The cooled air is blown out from a blowout port of the housing (not shown) as cold air.

[0035] The second blower 120 is disposed upstream of the heater 110 in the air flow direction, and blows air sucked from a suction port provided on the front side of the housing (not shown) to the heater 110. The air blown from the second blower 120 to the heater 110 exchanges heat with the refrigerant while passing through the heater 110, and flows out from an exhaust port (not shown) provided on the rear side of the housing (not shown). In such an air conditioner 101, the lower portion of the compressor body 10 and the upper portion to which the cover member 30 is mounted are fixed to the base plate 100 by the fixing member 40, so that vibration, noise and vibration of the compressor body 10 can be suppressed, and the power connector 20 connected to the upper end of the compressor body 10 can be suppressed from falling off. Thus, the load on the pipe 14 connected to the compressor body 10 and the refrigerant pipe 91 connected thereto can be suppressed, and the refrigerant circuit can be stably operated, thereby realizing smooth and quiet operation of the air conditioner 101. The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the specific structure is not limited to these embodiments, and even changes in design that do not deviate from the scope of the purpose of the present invention are also included in the present invention. In addition, as long as there are no special contradictions or problems in the purpose and structure of the above-mentioned embodiments, they can be combined using mutual technologies.
