DETAILED DESCRIPTION OF THE INVENTION

[0009] Hereinafter, a scroll air compressor will be described in detail as an example of the compressor of the present invention, with reference to the drawings as appropriate. <<Embodiment 1>>

[0010] FIG. 1A is a schematic diagram showing a scroll compressor S1 according to the first embodiment as viewed obliquely from above and in front. FIG. 1B is a schematic diagram showing a state in which the side plate 1i1, the front plate 101m, and the front A partition wall 202a (see FIG. 2A) that form the housing 101 of the scroll compressor S1 in the first embodiment are removed.

[0011] As shown in FIG. 1A, the scroll compressor S1 of the first embodiment has an outer shell formed by a housing 101. The housing 101 has a front panel 101m, a top panel 101t, a rear panel 101u (see FIG. 2B), side panels 1i1 and 1i2, and a bottom panel 101o. An electrical component box 204b is installed inside the side panel 1i1, and contains electrical components 204d (see FIG. 2C) that control the scroll compressor S1. An air intake 101a is provided in the side panel 1i1.

[0012] Inside housing 101 shown in FIG. 1B, a scroll compressor body 102, a motor 103, a control board 104, an air tank 105, an electric fan 106, and an air dryer 107 are installed. The scroll compressor body 102 compresses air supplied from an intake port 109. The motor 103 drives the scroll compressor body 102. The control board 104 controls the operation of the scroll air compressor S1. The air tank 105 stores the compressed air generated by the scroll compressor body .

[0013] An electric fan 106 cools an air tank 105 that stores high-temperature compressed air. An air dryer 107 dehumidifies the compressed air stored in the air tank 105. The air dryer 107 is connected to the air tank 105 by a pipe 108 that serves as a flow path for the compressed air. The scroll compressor body 102 has an inlet 109 for drawing in air. A filter 109f for removing dust from the air is installed on the peripheral surface 109s of the inlet 109. Note that, although the present embodiment exemplifies a case in which there are two inlets 109 and two filters 109f, the number of inlets 109 and filters 109f is not limited to two. For example, there may be one inlet 109 and one filter 109f, or three or more inlets 109 and filters 109f.

[0014] The scroll compressor body 102 and an air tank 105 that stores compressed air generated by the scroll compressor body 102 are connected by a rubber hose 110 . An exhaust port 101e of the air dryer 107 and an exhaust port 101s of the scroll compressor body 102 are opened in a top plate 101t of the housing 101. The air that has cooled the air dryer 107 is discharged from the exhaust port 101e. The air that has cooled the scroll compressor body 102 is discharged from the exhaust port 101s.

[0015] FIG. 2A is a schematic diagram showing a state in which a front plate 101m and a side plate 101i of a housing 101 of the scroll compressor S1 according to the first embodiment are removed. Figure 2B shows a schematic view of the scroll compressor S1 with the front plate 101m and the side plate 101i of the housing 101 removed, as seen from the upper rear left diagonally.

[0016] Figure 2C shows a schematic view of the scroll compressor S1 with the rear plate 101u of the housing 101 removed, as seen from the upper rear left diagonally. Note that in Figure 2C, the lid of the electrical component box 204b is removed.

[0017] <Machine room 201> As shown in Figure 2A, the interior of the housing 101 is divided into a machine room 201, a chamber A 203, and a chamber B 204. In the housing 101, a front A partition wall 202a and a rear A partition wall 202b (see Figure 3) that separate the machine room 201 from the rear chamber A 203 and the front chamber B 204, which are the other spaces, are installed. The A partition wall 202 has a front A partition wall 202a and a rear A partition wall 202b. The rear A partition wall 202b is fixed to the housing 101. Note that the front A partition wall 202a and the rear A partition wall 202b may be collectively referred to as the A partition wall 202.

[0018] The front A partition wall 202a as the A partition wall 202 is configured to be removable by the user. Figure 3 shows a schematic view of the scroll compressor S1 in Embodiment 1 with the outer plate of the housing 101 and the air tank 105 (see Figure 2A) removed, as seen from the right side. A handle 402 for the user to grip is installed at the upper front of the front A partition wall 202a.

[0019] As shown in Figure 1B, a B partition wall 205 that divides the chamber A 203 and the chamber B 204, which are the spaces other than the machine room 201, is installed in the housing 101. The scroll compressor main body 102 and the motor 103 are installed in the machine room 201.

[0020] <Chamber A 203> An air tank 105 is arranged in the chamber A 203. An air intake port 206 for introducing outside air is formed at the lower rear part of the rear A chamber 203. By arranging the air intake port 206 behind the lower part of the air tank 105, the air tank 105 is cooled by the cold air passing through the air intake port 206. As shown in FIG. 4A, by generating an air flow by the electric fan 106 in the tank chamber of the A chamber 203, cold air flows from the bottom to the top. Also, since cold air tends to accumulate at the lower side, it is more effective to arrange the air intake port 206 at the lower part.

[0021] As shown in FIG. 2B, an exhaust port 101f is installed at the upper part of the rear plate 101u of the housing 101 behind the electric fan 106. In addition, intake ports 101h for the scroll compressor body 102 and intake ports 101d1, 101d2 for the air dryer 107 are installed on the rear plate 101u of the housing 101. Thus, the scroll compressor body 102 is cooled by the air entering from the intake port 101h of the rear plate 101u. The air dryer 107 is cooled by the air entering from the intake ports 101d1, 101d2 of the rear plate 101u.

[0022] <00​​​​​​​​​​As shown in FIG. 2C, exhaust duct 111 is formed by being surrounded by rear A partition wall 202b, duct side partition wall 111a, duct upper partition wall 111b, bottom plate 101o, and top plate 101t. A straightening vane 111o is installed inside the exhaust duct 111. The straightening vane 111o reduces the speed of the air sent into the exhaust duct 111 to promote heat absorption. The air flow in the exhaust duct 111 will now be described.

[0025] Cool air from the outside is drawn into the housing 101 through the air intake 101h in the rear plate 101u shown in FIG. 2B (black arrow α21 in FIG. 2C). The air that enters the interior flows around to the front side of the housing 101, cools the scroll compressor body 102 (see FIG. 1B) installed in the front lower part of the housing 101, and then flows to the rear lower part of the housing 101 (white dashed arrow α22 in FIG. 2C). The air that enters the rear lower part of the housing 101 becomes an ascending air current (white arrow α23 in FIG. 2C) due to the air being blown by the sirocco fan 102C that cools the scroll compressor body 102. The ascending air hits the rectifying plate 111o and continues to rise while slowing down (white arrow α24 in FIG. 2C), and is then discharged to the outside through the exhaust port 101s in the top plate 101t (gray arrow α25 in FIG. 2C). Furthermore, by positioning the rectifying plate 111o so that the bottom plate 101o of the housing 101 cannot be seen when looking downward through the exhaust port 101s, the path of the ascending air current α23 can be blocked, which also has the effect of reducing noise. In other words, if there is a path through which air flows, vibrations will also be transmitted through the air. Therefore, noise can be reduced by preventing the air flow path from becoming a straight line.

[0026] <Ventilation vent 301> As shown in Figure 3, rear A partition wall 202b is provided with vent hole 301 (A vent), which is a hole that connects at least machine room 201 and A room 203. When airflow is generated in the tank chamber of A room 203 by electric fan 106 (see Figure 4A), cool air flows from bottom to top. Also, since cool air tends to accumulate at the bottom, it is more effective to locate vent hole 301 (A vent) at the bottom. Note that "bottom" includes below the center, the upstream side of the airflow, etc. The ventilation port 301 is located near the intake port 109 (see FIG. 1B) of the scroll compressor body 102 installed in the machine chamber 201. Cool air flows from the ventilation port 301 into the scroll compressor body 102. This allows the scroll compressor body 102 to be cooled effectively, improving efficiency and performance.

[0027] <Ventilation vent 302> The front A partition wall 202a has a vent port 302 (B vent port) that communicates with the B chamber 204. The air inside the B chamber 204 passes through the vent port 302 and enters the machine chamber 201, cooling the scroll compressor body 102.

[0028] 2A, a rubber hose 110 that connects the scroll compressor body 102 and the air tank 105 passes through the vent 302. Therefore, the rubber hose 110 can be cooled by the air passing through the vent 302.

[0029] <Slit 303> The front A partition wall 202a has a slit 303 that connects the machine chamber 201 and the B chamber 204. The slit 303 is different from the vent 301 (vent A) of the rear A partition wall 202b and the vent 302 (vent B) of the front A partition wall 202a shown in FIG. 3 . The slit 303 is located near the filter 109f of the suction port 109 of the scroll compressor body 102. This allows cold air to be effectively supplied from the slit 303 to the filter 109f installed in the suction port 109. In other words, the scroll compressor body 109 can take in cold air (air before being heated by devices such as the motor 103) from the suction port 109 via the filter 109f, thereby improving compression efficiency and performance.

[0030] The slits 303 have a rectangular shape with a short vertical dimension and a long horizontal dimension. Each of the two slits 303 is located above the suction port 109 of the scroll compressor body 102. This is because the air in chamber B 204 is layered by passing through the slits 303, thereby blocking the air heated by the motor 103 installed above the scroll compressor body 102. The air in chamber B 204 is then supplied to the suction port 109 of the scroll compressor body 102 through the slits 303. This allows the cool air in chamber B 204 to be supplied to the suction port 109 from the slits 303.

[0031] 3, the two slits 303 are arranged below and parallel to a parallel portion 108h of a pipe 108 that connects the air dryer 107 and the air tank 105, and above the suction port 109 of the scroll compressor body 102. The upper slit 303 is arranged between the lower slit 303 and the motor 103 when viewed from the side. The shape and arrangement of the slit 303 allows the airflow from the motor 103 to be separated from the air from the chamber B 204 in a layered air manner. In this way, the slit 303 is installed near the piping 108 of the air dryer 107 and the motor 103. This allows the piping 108 and the motor 103 to be cooled.

[0032] Noise from the scroll compressor body 102 and the like generated in the machine chamber 201 passes through the front A partition wall 202a and the rear A partition wall 202b, reverberates on the inner wall surface of the casing 101 in the A chamber 203 or the B chamber 204, and is then released to the outside of the casing 101. This makes it possible to reduce the noise level of the scroll compressor S1.

[0033] FIG. 4A is a schematic diagram showing a state in which a side plate 1i1 and a front plate 101m of a housing 101 of the scroll compressor S1 according to the first embodiment are partially removed. FIG. 4B is a schematic diagram showing the scroll compressor S1 of the first embodiment with the side plate 1i1 of the housing 101 removed and the front A partition wall 202a removed, as viewed from the left side. As shown in FIG. 3, part of the outside air taken in through the intake port 206 of the rear panel 101u passes through the A room 203 and enters the machinery room 201 through the vent 301 (A vent) of the rear A partition wall 202b. The airflow from the A vent port 301 branches and flows toward the motor 103 side and the suction port 109. Specifically, the flow path from the A vent port 301 to the motor cooling fan (electric fan 106) via the motor 103 is different from the flow path from the A vent port 301 to the suction port 109. In this way, cool air is supplied to the scroll compressor body 102 through the A vent port 301. That is, in terms of the positional relationship with the sirocco fan 103c, the suction port 109 is disposed close to the intake port 206. Therefore, the suction port 109 can suck in the cool air from the intake port 206 (air before being heated by devices such as the motor 103), improving the compression efficiency.

[0034] 3 is disposed between the electric fan 106, which is a cooling fan for the motor 103 (see FIG. 1B), and the intake port 109. These measures reduce the intake resistance of the intake port 109, thereby improving performance. In other words, in terms of its position relative to the electric fan 106, the intake port 109 is located in a position where it can draw in cool air (air before being heated by devices such as the motor 103) from the air vent 301, which contributes to improving compression efficiency.

[0035] As shown in Fig. 4A, outside air taken in from around air dryer 107 at the upper front of housing 101 is supplied to chamber B 204 through air vent C 401 (white arrow α11 in Fig. 4A). The air supplied from air vent C 401 (white arrow α11 in Fig. 4A) flows along piping 108 and is supplied to scroll compressor body 102 through slit 303 and vent 302. Pipe 108 is cooled by the airflow indicated by white arrow α11 in Fig. 4A, thereby reducing the temperature of the compressed air supplied to air dryer 107 and making it possible to reduce the load on air dryer 107.

[0036] 4A, air is supplied to the intake port 109 of the scroll compressor body 102. This cools the motor 103 inside the machine chamber 201, prevents the intake of heated air, and reduces the intake air temperature, thereby improving performance. In the first embodiment, as shown in Fig. 4B, a handle 402 is provided on the front A partition wall 202a. During regular inspection, a user can grasp the handle 402 and pull the front A partition wall 202a toward themselves. In this way, by providing the handle 402 on the front A partition wall 202a, handling when pulling the front A partition wall 202a toward themselves is improved.

[0037] 2A, the front A partition wall 202a is fixed to the front side, which is easily accessible, by bolts b1, fitting, etc. For example, when fixing the front A partition wall 202a, the front A partition wall 202a can be fixed by fastening bolts at several points on the front side and fitting protrusions on the bottom of the front A partition wall 202a into notches in the bottom plate 101o. Note that the front A partition wall 202a may also be configured to be fixed without using bolts b1. When the front A partition wall 202a is fixed, elastic bodies 202d (see FIG. 4B) are pressed against the top and back sides to ensure airtightness, suppress vibration, and improve maintainability. The elastic body 101d (see FIG. 3) on the top side is installed in the housing 101.

[0038] According to the above configuration, as shown in Fig. 3, front A partition wall 202a and rear A partition wall 202b are provided, and as shown in Fig. 2A, machine room 201 is separated from rear A room 203 and front B room 204, and B partition wall 205 is installed to divide the space other than machine room 201 into A room 203 and B room 204. Then, as shown in Figs. 2A and 3, air intake 206, vent 301, vent 302, etc. are provided. This makes it possible to realize a scroll compressor that achieves both reduced noise and a lower intake air temperature.

[0039] The positions, numbers, and areas of the ventilation holes 301 (see FIG. 3), the ventilation holes 302, and the slits 303 may be changed. <<Embodiment 2>>

[0040] FIG. 5 shows a schematic diagram of the layout of the scroll compressor S2 of the second embodiment as viewed from above. In the scroll compressor S2 of the second embodiment, the chamber A 203 is disposed on the front side, and the chamber B 204 is disposed on the rear side. The other configurations are the same as those in the first embodiment. As a result, the chamber B 204, which has a large internal volume, is arranged at the rear side, so that the depth dimension can be reduced and the size can be reduced.

[0041] Alternatively, by arranging chamber B 204, which has a large free volume inside, at the rear side, it is possible to enlarge exhaust duct 111 shown in Fig. 2C. This improves the cooling performance of sirocco fan 102c (see Fig. 1B), thereby improving performance and thereby improving the performance of scroll compressor S1.

[0042] As shown in FIG. 5, a machine room 201 and an exhaust duct 111 are provided on the sides of the A room 203 and the B room 204 . An intake port 206 (also see FIG. 2B) is provided at the rear lower portion of chamber B 204 of housing 101 of scroll compressor S2. An air tank 105 is installed in the A room 203. An air intake port 203k for cooling the air tank 105 in the A room 203 is opened at the bottom of the side of the housing 101 that forms the A room 203.

[0043] The scroll compressor body 102 is provided in the lower part of the machine chamber 201, and the driving motor 103 is provided in the upper part. Therefore, the machine chamber 201 generates noise due to operation. A sound-absorbing material is more effective in preventing noise when it is attached to a position that is far from the machine room 201 and has a large surface area. Therefore, a sound-absorbing material 204v is attached to the inner surface of the housing 101 on the side of the room B 204. To further enhance the soundproofing effect, a soundproof partition 204s may be provided, or a sound-absorbing material 204v0 may be attached to the partition 204s.

[0044] According to the above configuration, the scroll compressor S2 has a high soundproofing effect. It is also possible to provide only the soundproof partition 204s without providing the sound absorbing material 204v, or to provide only the partition 204s and the sound absorbing material 204v0. In the scroll compressor S1 similar to that of the first embodiment, the positional relationship between the machine chamber 201, the chamber A 203, and the chamber B 204 may be changed as in the following other example.

[0045] <Another example 1> FIG. 6 is a schematic diagram showing the layout of a scroll compressor S21 according to a first modified example of the second embodiment, as viewed from above. The scroll compressor S21 of the other example has the same arrangement of the machine chamber 201, the A chamber 203, and the B chamber 204 as the scroll compressor S2 of the second embodiment. The soundproof partitions 204s1, 204s2, 204s3, and 204s4 are arranged alternately so that their tip ends partially overlap, thereby enhancing the soundproofing effect.

[0046] Sound absorbing materials 204v1, 204v2, 204v3, and 204v4 may be attached to the soundproof partitions 204s1, 204s2, 204s3, and 204s4, respectively, thereby further enhancing the soundproofing effect. In the scroll compressor S1 of the first embodiment, the positional relationship between the scroll compressor body 102 and the motor 103 in the machine chamber 201 may be changed, as in the following alternative example 2.

[0047] <Another example 2> FIG. 7 is a schematic diagram showing a scroll compressor S22 according to another example of the second embodiment, as viewed from the chamber A 203 and chamber B 204 side. In the scroll compressor S22 of Alternative Example 2, the motor 103 is disposed in the lower part of the machine chamber 201, and the scroll compressor body 102 is disposed in the upper part. In this case, scroll compressor body 102 is disposed at the top, and therefore suction port 109 is located at the top. Therefore, two slits 303 are disposed slightly below suction port 109 on the side of motor 103 at the bottom. Slits 303, which are short in vertical dimension and long in horizontal dimension, send layered air to suction port 109, forming a curtain of air, so to speak, and preventing air heated by cooling motor 103 at the bottom from being drawn into suction port 109.

[0048] In other words, when the motor 103 is placed at the bottom and the scroll compressor body 102 is placed at the top inside the machine room 201, having the slit 303 on the motor side can prevent hot air from entering the intake port 109 after cooling the motor 103.
