[0036] Hereinafter, a scroll air compressor will be used as an example of the compressor of the present invention, with appropriate reference to the accompanying drawings for detailed description.
[0037] <<Implementation Method 1>>
[0038] exist Figure 1A The diagram shows a schematic view of the scroll compressor S1 in Embodiment 1 from an obliquely upward perspective.
[0039] exist Figure 1B The image shows the scroll compressor S1 in Embodiment 1 with the side plate 1i1, front plate 101m, and front partition wall 202a forming the housing 101 removed (see reference). Figure 2A A schematic diagram of the state of ).
[0040] like Figure 1A As shown, in the scroll compressor S1 of Embodiment 1, the outer profile is formed by the housing 101.
[0041] The housing 101 has a front panel 101m, a top panel 101t, and a rear panel 101u (for reference). Figure 2B Side plates 1i1, 1i2, and bottom plate 101o. Inside side plate 1i1, an electrical component 204d (see reference) is housed, which controls the scroll compressor S1. Figure 2C The electrical component box 204b is provided with an air inlet 101a on the side panel 1i1.
[0042] exist Figure 1B The interior of the housing 101 shown contains a scroll compressor body 102, an electric motor 103, a control circuit board 104, an air container 105, an electric fan 106, and an air dryer 107.
[0043] The scroll compressor body 102 compresses the air supplied from the suction port 109. The electric motor 103 drives the scroll compressor body 102.
[0044] The control circuit board 104 controls the operation of the scroll air compressor S1. The air container 105 stores the compressed air generated by the scroll compressor body 102.
[0045] An electric fan 106 cools the air container 105, which stores high-temperature compressed air. An air dryer 107 dehumidifies the compressed air stored in the air container 105. The air dryer 107 is connected to the air container 105 via a pipe 108 that serves as the flow path for the compressed air.
[0046] The scroll compressor body 102 has an intake port 109 for drawing in air. A filter 109f for removing dust from the air is provided on the circumferential surface 109s of the intake port 109. In this embodiment, two intake ports 109 and filters 109f are given as an example, but the number of intake ports 109 and filters 109f is not limited to two. For example, there may be one intake port 109 and one filter 109f, or there may be three or more.
[0047] The scroll compressor body 102 and the air container 105 storing the compressed air generated by the scroll compressor body 102 are connected by a rubber hose 110.
[0048] On the top plate 101t of the housing 101, an opening is formed for the exhaust port 101e of the air dryer 107 and the exhaust port 101s of the scroll compressor body 102.
[0049] Air cooled by the air dryer 107 is discharged from exhaust port 101e. Air cooled by the scroll compressor body 102 is discharged from exhaust port 101s.
[0050] exist Figure 2A The diagram shows the scroll compressor S1 in Embodiment 1 with the front panel 101m and side panel 101i of the housing 101 removed.
[0051] exist Figure 2B The diagram shows a scroll compressor S1 with its front panel 101m and side panel 101i removed, viewed from the upper left rear.
[0052] exist Figure 2C The diagram shows a view of the scroll compressor S1 from a slightly upper left rear angle, with the rear panel 101u of the housing 101 removed. Additionally, in... Figure 2C The image shows the state with the cover of the electrical components box 204b removed.
[0053] <Mechanical Room 201>
[0054] like Figure 2A As shown, the interior of the housing 101 is divided into a mechanical room 201, a room A 203, and a room B 204.
[0055] Inside the housing 101, there are front A partition wall 202a and rear A partition wall 202b that separate the machine room 201 from the rear A chamber 203 and the front B chamber 204, which are spaces other than this (see reference). Figure 3 ).
[0056] The partition wall 202 has a front partition wall 202a and a rear partition wall 202b. The rear partition wall 202b is fixed to the housing 101.
[0057] In addition, the front A partition wall 202a and the rear A partition wall 202b are sometimes collectively referred to as A partition wall 202.
[0058] The front A partition wall 202a, which serves as partition wall 202, is a component that the user can remove.
[0059] exist Figure 3 The image shows the scroll compressor S1 of Embodiment 1 viewed from the right side, with the outer panel of the housing 101 and the air container 105 removed (see reference). Figure 2A A schematic diagram of the state of ).
[0060] A handle 402 for user grip is provided on the upper part of the front A partition wall 202a.
[0061] like Figure 1B As shown, inside the housing 101, there is a partition wall 205 that separates the A chamber 203, which is a space other than the machine room 201, from the B chamber 204.
[0062] The machine room 201 contains a scroll compressor body 102 and an electric motor 103.
[0063] <Room A 203>
[0064] An air container 105 is installed in chamber A 203.
[0065] An air inlet 206 for introducing external gas is formed in the lower rear part of chamber A 203 on the rear side. By positioning the air inlet 206 at the lower rear of the air container 105, the air container 105 is cooled by the cold air passing through the air inlet 206.
[0066] like Figure 4A As shown, an electric fan 106 generates airflow within the container chamber A 203, causing cool air to flow from bottom to top. Furthermore, cool air tends to accumulate at the bottom, so positioning the air inlet 206 at the bottom is more effective.
[0067] like Figure 2B As shown, an exhaust port 101f is provided on the upper part of the rear panel 101u of the housing 101 located behind the electric fan 106. In addition, an air inlet 101h for the scroll compressor body 102 and air inlets 101d1 and 101d2 for the air dryer 107 are provided on the rear panel 101u of the housing 101.
[0068] Therefore, the scroll compressor body 102 is cooled by air entering from the air inlet 101h of the rear panel 101u. The air dryer 107 is cooled by air entering from the air inlets 101d1 and 101d2 of the rear panel 101u.
[0069] <Room B204>
[0070] exist Figure 1B In chamber B 204 shown on the front side, there is a piping 108 connecting the air dryer 107 to the air container 105, and a rubber hose 110 connecting the scroll compressor body 102 to the air container 105. Figure 2C As shown, chamber B 204 contains an electrical component box 204b for storing electrical components 204d, a solenoid valve for discharging wastewater (not shown), and other components. This allows for the storage of various components such as piping 108, rubber hoses 110, the electrical component box 204b, and the solenoid valve for discharging wastewater within the relatively spacious chamber B 204.
[0071] like Figure 3 As shown, the front A partition wall 202a and the rear A partition wall 202b that constitute the A partition wall 202 separate the machine room 201 from the rear A room 203 and the front B room 204.
[0072] <Exhaust passage 111>
[0073] like Figure 2C As shown, an exhaust channel 111 is formed by being surrounded by a rear A partition wall 202b, a channel side partition wall 111a, a channel upper partition wall 111b, a bottom plate 101o, and a top plate 101t.
[0074] A rectifier plate 111o is provided inside the exhaust passage 111. The rectifier plate 111o reduces the velocity of the air delivered to the exhaust passage 111, thereby promoting heat absorption.
[0075] The airflow in exhaust passage 111 is explained.
[0076] from Figure 2B The air inlet 101h of the rear panel 101u shown draws in cold air from outside into the interior of the housing 101. Figure 2C (Black arrow α21). The air that enters the interior flows around to the front of the housing 101 and impacts the scroll compressor body 102 located at the lower front of the housing 101 (see reference). Figure 1B After cooling, it flows to the lower rear part of the housing 101. Figure 2C (The dashed hollow arrow α22). The air entering the lower rear part of the housing 101 becomes an upward airflow due to the multi-blade fan 102C used to cool the scroll compressor body 102. Figure 2CThe hollow arrow α23). The rising air contacts the rectifier plate 111o and rises while decreasing in speed ( Figure 2C The hollow arrow α24) is discharged to the outside from the exhaust port 101s of the top plate 101t. Figure 2C (The gray arrow α25).
[0077] Furthermore, by arranging the rectifier plate 111o in such a way that the bottom plate 101o of the housing 101 is not visible when looking downwards from the exhaust port 101s, it can block the path of the rising airflow α23, thereby reducing noise. That is, since there is an airflow path, vibration is also transmitted through the air from there. Therefore, by making the airflow path non-linear, noise can be reduced.
[0078] <Ventilation Port 301>
[0079] like Figure 3 As shown, a vent 301 (A vent) is provided in the rear partition wall 202b A, which connects the machine room 201 and the A chamber 203. An electric fan 106 (see reference) is used within the container chamber of the A chamber 203. Figure 4A This generates airflow, with cold air flowing from bottom to top, and cold air tends to accumulate at the bottom. Therefore, it is more effective to position the vent 301 (vent A) at the bottom. In addition, "bottom" includes areas below the center and upstream of the airflow.
[0080] Vent 301 is located at the suction port 109 of the scroll compressor body 102 located in the machine room 201 (reference). Figure 1B Nearby, cold air flows from the vent 301 to the scroll compressor body 102. Therefore, the scroll compressor body 102 can be effectively cooled, improving efficiency and performance.
[0081] <Ventilation port 302>
[0082] The front partition wall 202a has a vent 302 (B vent) that communicates with chamber B 204. Air inside chamber B 204 enters the machine room 201 through the vent 302 to cool the scroll compressor body 102.
[0083] like Figure 2A As shown, the rubber hose 110 connecting the scroll compressor body 102 to the air container 105 passes through the vent 302. Therefore, the rubber hose 110 can be cooled by the air passing through the vent 302.
[0084] <Gap 303>
[0085] The front partition wall 202a has a slit 303 that connects the machine room 201 with the chamber 204. The slit 303 and... Figure 3The vent 301 (A vent) of the rear A partition wall 202b shown is different from the vent 302 (B vent) of the front A partition wall 202a. A slit 303 is provided near the filter 109f of the suction inlet 109 of the scroll compressor body 102. Therefore, cold air can be effectively supplied to the filter 109f provided at the suction inlet 109 through the slit 303. That is, cold air (air before being heated by the motor 103 or other equipment) can be introduced into the scroll compressor body 109 from the suction inlet 109 via the filter 109f, thus improving compression efficiency and performance.
[0086] The slits 303 have a rectangular shape with a short longitudinal dimension and a long transverse dimension. Two slits 303 are located above the suction inlet 109 of the scroll compressor body 102. This is to allow the air in chamber B 204 to become layered as it passes through the slits 303, thereby blocking the air heated by the electric motor 103 located above the scroll compressor body 102. The air in chamber B 204 is supplied to the suction inlet 109 of the scroll compressor body 102 through the slits 303. Thus, cold air from chamber B 204 can be supplied to the suction inlet 109 from the slits 303.
[0087] like Figure 3 As shown, two slits 303 are located below the parallel portion 108h of the pipe 108 connecting the air dryer 107 and the air container 105, and are arranged parallel to the parallel portion 108h above the suction inlet 109 of the scroll compressor body 102. Furthermore, the upper slit 303, when viewed from the side, is positioned between the lower slit 303 and the motor 103.
[0088] Based on the shape and configuration of the slit 303, the airflow from the motor 103 can be separated from the air from chamber B 204 using layered air. In this way, the slit 303 is positioned near the piping 108 of the air dryer 107 and the motor 103. This allows for the cooling of both the piping 108 and the motor 103.
[0089] The noise generated in the machine compartment 201, such as the scroll compressor body 102, is emitted to the outside of the housing 101 after echoing through the front partition wall 202a and the rear partition wall 202b, and then through the inner wall of the housing 101 in compartment A 203 or compartment B 204. Therefore, the noise level of the scroll compressor S1 can be reduced.
[0090] exist Figure 4A The diagram shows a scroll compressor S1 in Embodiment 1 with part of the side plate 1i1 and front plate 101m of the housing 101 removed.
[0091] exist Figure 4BThe diagram shows a view from the left of the scroll compressor S1 of Embodiment 1 with the side plate 1i1 of the housing 101 removed and the front partition wall 202a removed.
[0092] A portion of the external gas introduced from the air intake 206 of the rear panel 101u, such as Figure 3 As shown, after passing through chamber A 203, it enters the machine room 201 through the vent 301 (vent A) of the rear partition wall 202b.
[0093] The airflow from vent A 301 branches and flows towards the motor 103 side and the suction port 109. Specifically, the flow path from vent A 301 through the motor 103 to the motor cooling fan (electric fan 106) is different from the flow path from vent A 301 to the suction port 109. In this way, cold air is supplied to the scroll compressor body 102 through vent A 301.
[0094] That is, the intake port 109 is positioned close to the air inlet 206 due to its position relative to the multi-blade fan 103c. Therefore, cold air (air before being heated by the motor 103 or other devices) from the air inlet 206 can be drawn in through the intake port 109, thus improving compression efficiency.
[0095] in addition, Figure 3 The vent 301 of the rear partition wall 202b shown is located on the motor 103 (reference). Figure 1B The cooling fan 106 is positioned between the electric motor fan 106 and the intake 109. These methods reduce the suction resistance of the intake 109, thereby improving performance. Specifically, due to its position relative to the electric fan 106, the intake 109 is positioned to draw in cool air (air before it is heated by the electric motor 103 or similar equipment) from the vent 301, which helps improve compression efficiency.
[0096] like Figure 4A As shown, external gas introduced from around the air dryer 107 at the front upper part of the housing 101 is supplied to chamber B 204 through vent C 401. Figure 4A Hollow arrow α11). Air supplied from vent C 401 ( Figure 4A The hollow arrow α11) forms an airflow along the piping 108, which is supplied to the scroll compressor body 102 from the gap 303 and the vent 302. The piping 108 is... Figure 4A The airflow cooling indicated by the hollow arrow α11 reduces the temperature of the compressed air supplied to the air dryer 107, thereby reducing the load on the air dryer 107.
[0097] In addition, from Figure 4AThe slit 303 of the front partition wall 202a shown supplies air to the intake port 109 of the scroll compressor body 102. This prevents the intake of air that has been heated to cool the motor 103 inside the machine compartment 201, thus reducing the intake air temperature and improving performance.
[0098] In this embodiment 1, as Figure 4B As shown, a handle 402 is provided on the front A partition wall 202a. During periodic inspections, the user holds the handle 402 and pulls the front A partition wall 202a closer to the side. In this way, by providing the handle 402 on the front A partition wall 202a, the convenience of pulling the front A partition wall 202a closer to the side is improved.
[0099] like Figure 2A As shown, the front A partition wall 202a is fixed to the easily accessible front side using bolts b1, fitting, or other means. For example, when fixing the front A partition wall 202a, there are several bolt tightening positions on the front side, allowing the lower protrusion of the front A partition wall 202a to fit into the notch of the base plate 101c, thus securing the front A partition wall 202a. Alternatively, the front A partition wall 202a can also be fixed without using bolts b1.
[0100] When the front partition wall 202a is fixed, its top and back surfaces push against the elastomer 202d (see reference). Figure 4B This ensures airtightness, suppresses vibration, and improves maintainability. Additionally, the elastomer 101d on the top side (refer to...) Figure 3 It is set in the housing 101.
[0101] Based on the above structure, such as Figure 3 The diagram shows the setup of a front partition wall 202a and a rear partition wall 202b, as shown. Figure 2A As shown, the machine room 201 is separated from the rear A room 203 and the front B room 204 by a partition wall 205 (B room), thus dividing the space outside the machine room 201 into A room 203 and B room 204. Figure 2A , Figure 3 The device shown is equipped with an air inlet 206, an air vent 301, and an air vent 302.
[0102] This enables the creation of scroll compressors that balance noise reduction and lower intake air temperature.
[0103] Alternatively, the vent 301 can be modified (see reference). Figure 3 ), the location, quantity, and area of the vent 302 and the gap 303.
[0104] <<Implementation Method 2>>
[0105] exist Figure 5The diagram shows a configuration schematic of the scroll compressor S2 of Embodiment 2 as viewed from above.
[0106] In the scroll compressor S2 of embodiment 2, chamber A 203 is arranged on the front side and chamber B 204 is arranged on the rear side.
[0107] The other structures are the same as in Implementation Method 1.
[0108] Therefore, by placing the larger internal chamber B 204 at the rear, the depth can be reduced, thus achieving miniaturization.
[0109] Alternatively, by placing the larger B-chamber 204 at the rear, the interior space can be expanded. Figure 2C The exhaust passage 111 is shown. Thus, the multi-blade fan 102c (reference) Figure 1B The improved cooling performance of the scroll compressor S1 leads to improved overall performance.
[0110] like Figure 5 As shown, a mechanical room 201 and an exhaust passage 111 are provided on the side of chamber A 203 and chamber B 204.
[0111] An air inlet 206 is provided at the lower rear of chamber B 204 in the housing 101 of the scroll compressor S2 (see also...). Figure 2B ).
[0112] An air container 105 is provided in chamber A 203. An air inlet 203k is provided on the lower side of the housing 101 that forms chamber A 203 for cooling the air container 105 of chamber A 203.
[0113] In the machine compartment 201, the scroll compressor body 102 is located at the bottom, and the drive motor 103 is located at the top. Therefore, operating noise is generated in the machine compartment 201.
[0114] The sound insulation effect is greater when the sound-absorbing material is pasted in a location that is away from the machine room 201 and where a larger surface area can be formed. Therefore, sound-absorbing material 204v is pasted on the inner surface of the enclosure 101 on the side of chamber B 204.
[0115] In addition, to further improve the sound insulation effect, soundproofing partitions 204s can be installed. Alternatively, sound-absorbing material 204v0 can be pasted onto the partitions 204s.
[0116] Based on the above structure, a scroll compressor S2 with high sound insulation effect can be obtained.
[0117] Alternatively, the sound-absorbing material 204v may not be provided, and only the sound-insulating partition 204s may be provided, or only the partition 204s and the sound-absorbing material 204v0 may be provided.
[0118] Alternatively, in the same scroll compressor S1 as in Embodiment 1, the positional relationship of the mechanical chamber 201, chamber A 203, and chamber B 204 can be changed as in other examples described below.
[0119] <Other Example 1>
[0120] exist Figure 6 The diagram shows a configuration of the scroll compressor S21 of another example 1 of embodiment 2, viewed from above.
[0121] In other examples of scroll compressor S21, the configuration of mechanical chamber 201, chamber A 203, and chamber B 204 is the same as that of scroll compressor S2 in embodiment 2.
[0122] The soundproofing partitions 204s1, 204s2, 204s3, and 204s4 are arranged in an alternating manner, with a portion of their front ends overlapping. This improves the soundproofing effect.
[0123] Alternatively, sound-absorbing materials 204v1, 204v2, 204v3, and 204v4 can be pasted onto the soundproofing partitions 204s1, 204s2, 204s3, and 204s4 respectively. This can further improve the soundproofing effect.
[0124] Alternatively, in the scroll compressor S1 of Embodiment 1, the positional relationship between the scroll compressor body 102 and the motor 103 in the machine room 201 can be changed as in other Examples 2 described below.
[0125] <Other Example 2>
[0126] exist Figure 7 The diagram shows a schematic of the scroll compressor S22 of Embodiment 2 as viewed from the sides of chamber A 203 and chamber B 204.
[0127] In the scroll compressor S22 of other example 2, an electric motor 103 is arranged at the lower part of the machine compartment 201, and a scroll compressor body 102 is arranged at the upper part.
[0128] At this time, because the scroll compressor body 102 is located at the top, the suction port 109 is also located at the top. Therefore, two slits 303 are respectively arranged slightly below the suction port 109 on the side of the lower motor 103. By using the slits 303, which have a short longitudinal dimension and a long transverse dimension, to deliver layered air to the suction port 109, a so-called air curtain is formed, which prevents the air heated by cooling the lower motor 103 from being drawn into the suction port 109.
[0129] That is, when the motor 103 is positioned below and the scroll compressor body 102 is positioned above inside the machine room 201, the gap 303 is located on the motor side, which can better prevent hot air after cooling the motor 103 from entering the intake port 109.
[0130] <<Variations 1-5>>
[0131] In the scroll compressor S1 of embodiment 1, for example by making the vent 301 (reference) Figure 3 ), gap 303 (reference) Figure 2A The area of the scroll compressor body 102 increases, affecting the suction port 109 (reference) of the scroll compressor body 102. Figure 1B Increasing the supply of air can improve performance.
[0132] The same reference numerals are used for structures identical to those in Embodiment 1, and their descriptions are omitted.
[0133] A variation of the slit 303 corresponding to the suction port 109 of the scroll compressor body 102 of Embodiment 1 is shown in the modified example.

[0147] Figure 11B In the modified example 4 shown, the slit 303d2 is formed as a hole with a flat curvature near the filter 109f on the peripheral surface 109s of the inlet 10.

[0154] According to the above-described modifications 1 to 5, it is possible to block the heated air after cooling the motor 103, and to draw in unheated air from the suction port 109 of the scroll compressor body 102.
