As shown in Fig. 6, at the rear of the cleaner body 2, a first exhaust port 40A, a storage port 50A of the power supply line 3, and a second exhaust port 60A are provided. Further, in the present embodiment, since the first exhaust port 40A, the storage port 50A, and the second exhaust port 60A are all provided in the upper body casing 2A, for example, the second exhaust pipe is applied to the upper body casing 2A. The processing of the port 60A is sufficient, so the cost is relatively low. The first exhaust port 4A is formed in the upper portion of the cleaner body 2, and an elongated slot-shaped long hole 41 is formed in the vertical direction, and each of the long holes 41 is disposed at equal intervals in the left-right direction. Further, the first exhaust port 40A is formed to face obliquely upward (see Fig. 4). However, the first exhaust port 40A may be formed on a surface facing the horizontal.

The upper surface 42a and the lower surface 42b of each of the reinforcing ribs 42 are formed in the horizontal direction (see Fig. 4). Therefore, the surface on which the first exhaust port 40 A is formed is inclined upward, but the exhaust gas from the first exhaust port 40A is formed to be discharged from the cleaner body 2 in the horizontal direction along the horizontal plane of the reinforcing rib 42. However, the upper surface 42a and the lower surface 42b of each of the reinforcing ribs 42 may be inclined upward with respect to the horizontal direction, so that the exhaust gas from the first exhaust port 4A is discharged obliquely upward from the cleaner body 2. 201216911 The accommodating port 50A is an opening that is formed in a slightly square shape toward the side surface (backward in the horizontal direction), and is a passage when the wire is wound or when the wire is pulled out, and is housed in a state in which the plug PG constituting the power source wire 31 faces the side surface. Further, the storage opening 50A is located between the center of the cleaner body 2 in the left-right direction and the left end of the first exhaust port 40A. Further, the long hole 41 is formed in a short portion of the position at which the port 50A is accommodated, and the storage opening 50A is formed to enter the long hole 41 side. Further, during operation, since the power supply line 3 1 (see FIG. 5) is heated, air (intake) flows into the power supply line 31 for cooling, and after the power supply line 3 1 is cooled, air is formed from the storage opening 5 0 A. The gap is discharged from the cleaner body 2 to the outside. In the present embodiment, the storage port 510A is included in the first exhaust port 40A. The second exhaust port 60A is formed on the lower side of the first exhaust port 40A with the storage port 50A interposed therebetween. Further, the second exhaust port 60A has a horizontally long shape extending in the left-right direction, and is formed to extend to the lower side of the left-side storage opening 50A than the center in the left-right direction. In the rear portion of the cleaner body 2, when the cleaner 1A is formed to protrude rearward between the first exhaust port 40A and the second exhaust port 60A, the cleaner body 2 is raised and stored on the ground. A support portion T1 that abuts and supports (see Fig. 4). As shown in FIG. 7, the second exhaust port 60 is integrally formed of a synthetic resin or the like to form the exhaust member 61 by being fitted to a predetermined notch hole formed in the rear portion of the cleaner body 2 (see FIG. 6). The way of the schema is installed. Thus, the upper body casing 2 is formed with the first exhaust port 40Α.

S -12-201216911, since it is only necessary to form a notch hole for mounting the second exhaust port 60A, it is easy to change the design and is inexpensive. The exhaust member 61 has a frame body 62 having a substantially rectangular shape. The frame 62 is composed of an upper frame portion 62a constituting a frame on the upper side in the vertical direction, a lower frame portion 62b constituting a lower frame, a left frame portion 62c constituting a frame on the left side, and a right frame portion 62d constituting a frame on the right side. Composition. Therefore, the flow path R of the second exhaust port can be configured by the inner wall surface of the upper frame portion 62a, the inner wall surface of the lower frame portion 62b, the inner wall surface of the left frame portion 62c, and the inner wall surface of the right frame portion 62d. . The cross-sectional shape of the opening of the exhaust member 61 may be replaced by a slightly smaller shape, a slightly elliptical shape, or a slightly rounded shape instead of a substantially four-dimensional horizontally long shape. Further, in the exhaust member 61, two lateral ribs 63a and 63b which are formed to traverse the second exhaust port 60A (see Fig. 4) in the left-right direction are formed inside the casing 62. The lateral ribs 63a and 63b are a left frame portion 62c and a right frame portion 62d which are formed to extend to the frame 62 at the left and right ends. They are arranged in parallel in the upper and lower directions. By arranging two transverse ribs 63a, 63b, three flow paths R are formed in the upper and lower directions. However, the two transverse ribs 63a, 63b may not be provided. Further, in the exhaust member 61, two longitudinal ribs 64, 64 are formed inside the casing 62 so as to traverse the second exhaust port 60A (see Fig. 4) in the upper and lower directions. Each of the longitudinal ribs 64 is formed in a slightly triangular shape in a side view. By arranging the two longitudinal ribs 64, 64, three flow paths are divided in the left-right direction. However, the two longitudinal ribs 64, 64 may not be provided. Further, the exhaust member 61 is formed with two reinforcing ribs 65, 65 that traverse the second exhaust port 60A in the vertical direction between the vertical rib 64 and the vertical rib 64.

S -13-201216911 Further, a reinforcing rib 66 that crosses the vertical direction is formed between the vertical rib 64 and the left frame portion 62c, and a vertical cross-sectional direction is also formed between the vertical rib 64 and the right frame portion 62d. Rib 66. However, the two reinforcing ribs 65, 65 may or may not be present. Further, the opening cross-sectional shape of each hole of the second exhaust port 60 A is formed by the frame body 62, the two lateral ribs 63a and 63b, the two longitudinal ribs 64 and 64, and the two reinforcing ribs 65 and 65. The shape of the opening of the second exhaust port 60A may be a slightly smaller shape, a slightly elliptical shape, or a slightly rounded shape. As shown in Fig. 8, the length of the upper wall surface 62a1 which is the inner wall surface of the upper frame part 62a is L1, and the length of the lower wall surface 62b1 which is the inner wall of the lower frame part 62b is L2. The formation length L1 is longer than the length L2. Further, the length L1 of the upper wall surface 62al refers to the length from the inlet edge portion of the exhaust gas on the surface in contact with the exhaust gas (air) to the outlet edge portion. Further, the length L2 of the lower wall surface 62b1 also refers to the length from the inlet edge portion of the exhaust gas on the surface in contact with the exhaust gas (air) to the outlet edge portion, similarly to the upper wall surface 62a1. Further, in the lateral rib 63a of the exhaust member 61, the length of the upward wall surface 63al is L3, and when the length of the downward wall surface 63a2 is L4, the length L3 and the length L4 are the same length. Further, the length L3 of the wall surface 63al and the length L4 of the wall surface 63a2 are shorter than the length L1 of the upper wall surface 62al. Further, the length L3 and the length L4 are not limited to the same length, and may be set to L3 > L4 (may be L1 > L3). Further, the lateral rib 63b' of the exhaust member 61 has the length of the upward wall surface 63b1 as L5 and the length of the downward wall surface 63b2 as L6.

-14- 201216911 The length L5 is the same length as the length L6. Further, the length L5 of the wall surface 63b1 and the length L6 of the wall surface 63b2 are shorter than the length L4 of the wall surface 63a2, and are formed longer than the length L2 of the lower wall surface 62b1. Further, similarly to the above, L5 and L6 are not limited to the same length, and may be L5 > L6 (may be L6 > L2, L4 > L5). Further, the exhaust member 61 is formed such that the upper wall surface 62a1, the lower wall surface 62b1, and the wall surfaces 63&1, 63&2, 6311, and 6312 are formed upward with respect to the horizontal direction, and are formed at an angle with respect to the horizontal direction. Become α (for example, 15 degrees) (see Figure 8). Further, the exhaust member 61 is formed with a weir portion 62e outward in the rear end portion of the casing 62. In other words, the upper frame portion 62a faces downward in the vertical direction, faces the lower side in the vertical direction with respect to the lower frame portion 62b, faces the left side with respect to the left frame portion 62c, and faces the right side with respect to the right frame portion 62d. Further, in Fig. 8, only the up and down direction is shown. The crotch portion 62e is formed such that its front surface 62e is flush with the rear plate 2p (see Fig. 9) of the cleaner body 2. Therefore, the flow path R formed by the upper wall surface 62a1, the lower wall surface 62b1, and the wall surfaces 63a1, 63a2, 63b1, 63b2 is formed to protrude toward the inner side of the cleaner body 2 (see Fig. 4). That is, the upper wall surface 62a constituting the exhaust member 61 protrudes toward the inner side of the cleaner body 2. Therefore, the surface of the rear plate 2p of the cleaner body 2 is formed such that only the thickness of the crotch portion 62e protrudes outward, in other words, the amount of formation (protrusion amount) of the inside of the cleaner body 2 toward the upper frame portion 62a on which the upper wall surface 62al is formed, Is a lower frame that is formed to have a lower wall surface 62bl

S -15- 201216911 The amount of formation (protrusion amount) of the inside of the cleaner body 2 of the part 62b is larger. Further, in the present embodiment, the exhaust member 61 of the second exhaust port 60A is configured by another member (other components). However, the present invention is not limited thereto, and the main body casing 2A may be directly connected to the cleaner body 2 (integrated The flow path R as the second exhaust port 60A is formed. As shown in Fig. 9, the exhaust gas discharged from the discharge port 22a of the electric blower 20A is printed with a white arrow, as shown in (a), between the electric blower 20A and the rear plate 2p of the cleaner body 2. The air flow path R1 rises. Further, as indicated by (b) and (c) printed with white arrows, the first exhaust port 40A is discharged toward the rear in the horizontal direction. At the same time, as indicated by the white arrow (d), the second exhaust port 60A formed between the discharge port 22a of the electric blower 20A and the first exhaust port 40A is discharged obliquely upward with respect to the horizontal direction. . Further, the exhaust gas discharged from the discharge port 22a of the electric blower 20A is also guided to the side of the electric wire reel 30, and flows radially to the outer peripheral direction through the center portion of the electric wire reel 30 to the power supply line 3 1 ( See Figure 5 (a)). At this time, the exhaust gas flows through the gap between the power source line 31 and the power source line 3 1 to cool the power source line 31. The exhaust gas discharged to the outside of the power supply line 31 is discharged in the horizontal direction from the gap of the storage port 50A toward the rear of the cleaner body 2 (see FIG. 5(b)), and from the second exhaust port 60A. The left portion is discharged upward with respect to the horizontal direction. As shown in Fig. 9, as shown by (c) which is printed with a white arrow, the row is discharged from the first exhaust port 40A and the storage port 50A of the wire reel 30 (see Fig. 5 (b)) toward the rear in the horizontal direction. Gas, as shown in Figure 9 by the white arrow

(d) of S-16-201216911, 'the exhaust gas which is discharged obliquely upward from the second exhaust port 6A is interfered with the rear of the cleaner body 2, and as a result, as shown by the white arrow in FIG. e) shows that the upward exhaust is formed with respect to the horizontal direction to form a flow to the rear. Further, as shown in FIG. 1A, the exhaust gas discharged from the second exhaust port 6A is formed by a flow path between the upper wall surface 62al and the wall surface 63al as indicated by a white arrow mark. The flow path formed between the wall surface 63a2 and the wall surface 63b1 and the flow path formed between the wall surface 63b2 and the lower wall surface 62b1 are inclined along the inclination of the upper wall surface 62al, the lower wall surface 62b1, the wall surface 63al, 63a2, 63b1, 63b2, 63b2 flow. However, the exhaust gas passing through the upper wall surface 62a1, the lower wall surface 62b1, the wall surfaces 63a1, 63a2, 63b1, 63b2 is formed to have a larger inclination $ from the inclination a, that is, further upward than the inclination α from the second exhaust port. 60 Α was discharged. That is, since the length L1 of the upper wall surface 62a (see FIG. 8, the same applies hereinafter) is longer than the length L3 of the wall surface 63al, the friction of the exhaust gas flowing along the upper wall surface 6 2 a 1 is higher than that along the wall surface. Since the friction of the flowing exhaust gas is larger, the angle of the exhaust gas when the second exhaust port 60A comes out is inclined toward the upper wall surface 62a side, and the flow path from the second exhaust port 60A is formed. R is discharged. And this effect is called the Coanda effect. Similarly, since the length L4 of the wall surface 63a2 is longer than the length L5 of the wall surface 63b1, the wall surface 63a2 side is inclined toward the flow path R from the second exhaust port 60A. Further, the wall surface 63b2 and the lower wall surface 62b1 are also inclined on the side of the wall surface 63b2.

The state of S -17-201216911 is discharged from the flow path R of the second exhaust port 60A. Further, the first exhaust port 40A is located further on the downstream side of the exhaust flow path R1 of the electric blower 20A in the cleaner body 2 than the second exhaust port 60A, that is, the second exhaust port 60A is located at the electric Since the blower 20A is between the exhaust passages of the first exhaust port 4A, a pressure loss occurs between the second exhaust port 60A and the first exhaust port 40A, and the second exhaust gas from the upstream side is generated. The port 60A exhaust gas is discharged more aggressively than the first exhaust port 40A (the flow rate is fast). In addition, since the second exhaust port 60A is protruded inward with respect to the rear plate 2p of the cleaner body 2, the flow path R is formed, so that the exhaust flow path R1 between the electric blower 20A and the rear plate 2p is shortened. The gas easily flows into the second exhaust port 60A from the exhaust flow path R1, and the exhaust gas from the second exhaust port 60A easily flows out. Further, the opening surface of the second exhaust port 60A that protrudes into the cleaner body 2 is not inclined in the horizontal direction, but is inclined upward, that is, the upper wall surface is closer to the cleaner body than the lower wall surface of the second exhaust port 60A. 2 highlighted inside. Therefore, the opening surface of the second exhaust port 60A that protrudes into the cleaner body 2 is opposed to the direction in which the exhaust gas slightly flows upward from the lower side of the exhaust flow path R1, so that the exhaust gas is easily discharged from the exhaust flow path. R1 flows into the second exhaust port 60A, and the exhaust gas from the second exhaust port 60A easily flows out. Therefore, the exhaust gas from the second exhaust port 60A and the exhaust gas from the first exhaust port 40A are dry and overcome, and the exhaust gas can be discharged horizontally upward from the first exhaust port 40A. Further, regarding the sound of the exhaust gas, the length of the flow path from the electric blower 20A to the first exhaust port 40A is set to be long, so that the exhaust sound can be reduced. However, when a large amount of exhaust gas is discharged from the first exhaust port 40A, -18-201216911, dust that is rolled up on the ground is formed. Here, the second exhaust port 60A having a flow rate higher than that of the first exhaust port 40A is provided on the upstream side, and by discharging a small amount of exhaust gas from the second exhaust port 60 A, the exhaust sound is not increased by the transition. It can suppress the rolling of dust on the ground. The opening area of the second exhaust port 60A is made larger than the opening area of the first exhaust port 40A, and the flow velocity of the exhaust gas from the second exhaust port 60A can be accelerated. As described above, in the cleaner 1A of the first embodiment, since the flow path of the second exhaust port 60A is formed to be inclined upward with respect to the horizontal direction, and the length of the upper wall surface 62al is longer than the length of the lower wall surface 63b1, the The exhaust of the second exhaust port 60A and the exhaust gas from the horizontal direction of the first exhaust port 40A can form a smaller inclined surface (less upward surface), and can form an exhaust upward as a whole. (Refer to Figure 9), and it is possible to suppress the rolling of dust on the ground. Further, in the first embodiment, the hole of the second exhaust port 60A is not vertically upward but can be oriented upward in the horizontal direction, and can be set to a smaller inclination by the aforementioned Coanda effect, so that it can be effectively suppressed. Intrusion of foreign matter such as liquid or dust. Further, in the first embodiment, since the exhaust gas from the second exhaust port 610A is set obliquely upward, it is possible to prevent the exhaust gas from coming into contact with the user's clothes, face, etc., and to prevent the user from feeling Comfortable. In the first embodiment, the second exhaust port 60A protrudes almost rearward from the surface of the rear plate 2p of the cleaner body 2 (in the present embodiment, only the thickness of the crotch portion 62e protrudes), in other words, the second row The port 60A is located further in front than the straight line (dashed line) connecting the support portion T1 and the contact point Q1 of the wheel w (the state in which the cleaner body 2 is raised is located above)

S -19- 201216911 ) (refer to FIG. 4 ), it is not necessary to move the position of the wheel W of the cleaner body 2 rearward, and the vacuum cleaner body 2 is not enlarged. Further, in the first embodiment, the length L1 of the upper wall surface 6hl (the wall surface close to the first exhaust port) is formed more than the length L3 of the wall surface 63al (the wall surface facing the near wall). Further, the length L4 of the wall surface 63a2 (close to the wall surface of the first exhaust port) is longer than the length L5 of the wall surface 63b1 (the wall surface facing the near wall). Further, the length L6 of the wall surface 63b2 (the wall surface close to the first exhaust port) is longer than the length L2 of the lower wall surface 62b1 (the wall surface facing the near wall). Therefore, it is possible to provide exhaust gas that is more upward (inclined/3) than the inclination α of the upper wall surface 62al, the lower wall surface 62b1, the wall surfaces 63al, 63a2, 63b1, and 63b2. In this way, the exhaust gas and the exhaust gas from the first exhaust port 40Α can be dried on the flow path R formed by a small inclined surface (less upward surface) to form an overall inclined upward row. gas. Therefore, the dust of the ground can be prevented from being rolled up. In other words, in the first embodiment, the amount of formation (protrusion amount) of the inside of the cleaner body 2 (the rear plate 2p) of the upper wall surface 62 a 1 is formed to form a flow path to the second exhaust port 60A. The amount of formation (protrusion amount) of the inside of the cleaner body 2 (the rear plate 2p) of the lower wall surface 62b1 of the wall surface of the R is longer (large), so that the flow path R of the relatively small inclined surface can be made. The exhaust gas and the exhaust gas from the first exhaust port 40A are dried to form an exhaust gas that is inclined upward as a whole. In the first embodiment, the second exhaust port 60A is extended to a position overlapping the storage port 50A of the power supply line 31, that is, the second exhaust port 60A is positioned below the storage port 50A. On the side, -20-201216911, the storage port 50 A (direction in the horizontal direction) is disposed to the side, and the exhaust gas is discharged in the horizontal direction, or the exhaust gas from the second exhaust port 60A may be inclined upward. The exhaust gas from the storage port 5 Ο A is formed into an exhaust gas that is inclined upward. Therefore, the exhaust of the storage port 50A with respect to the outlet of the cooling air (exhaust gas) from the power supply line 31 can suppress the rolling of dust on the ground. When the direction of the exhaust gas from the first exhaust port 40 A is inclined upward, the second exhaust port 6 Ο A is not formed on the lower side of the first exhaust port 4 Ο A, and may be formed only in the accommodating port 50A. Lower side. In the first embodiment, the second exhaust port 60A is formed in the middle of the exhaust flow path R1 from the discharge port 22a of the electric blower 20A to the first exhaust port 40A. Therefore, the second exhaust port 60A is formed. The upper wall surface 62a1 of the flow path R is formed to protrude in the flow path of the exhaust gas flow path inside the cleaner body 2 (see FIG. 10 and the like), so that the exhaust gas easily flows out from the second exhaust port 60A. Further, since the exhaust gas in a state where the flow velocity is high can be discharged from the second exhaust port 60A, the exhaust gas from the first exhaust port 4 Ο A can be made upward. (Second Embodiment) Fig. 11 is a perspective view showing the appearance of a vacuum cleaner according to a second embodiment, and Fig. 12 is a longitudinal sectional view of the cleaner of Fig. 11. In the first embodiment, the dust collector 1A of the dust box type that can be reused by discharging dust without using a paper cassette is exemplified as an example. However, in the second embodiment, the carton type must be replaced. The vacuum cleaner 1B will be described. In the same manner as the second embodiment, the third embodiment is a carton type vacuum cleaner 1C.

S - 21 - 201216911 The vacuum cleaner of the present invention is applicable to any of a non-carton type and a paper cassette. In addition, the electric blower 20B (see FIG. 12) mounted on the vacuum cleaner 1B of the second embodiment is provided with a filter 25s (HEPA, ULPA, etc.) having a high dust collecting performance on the upper portion of the motor casing 21, and The upper portion of the 25s is provided with the exhaust gas (the air member that is discharged from the filter 25s to the bottom of the cleaner body 2). Therefore, the total amount of the exhaust gas flowing out of the motor casing 21 passes through the filter 25s, by the cover. The member 26 is guided to the bottom side of the electric blower 20B via the right side surface (the back side of the paper surface) of the motor housing 21. The vacuum cleaner 1B of the second embodiment has a rear portion of the dust suction main body 2 as shown in Fig. 11. The first exhaust port 4B, the accommodating port 50B, and the second port 60B1, 60B2. The rear portion of the cleaner body 2 has a rear surface 2pl and a rear plate 2p facing the rear rear side 2p2 (see Fig. 12). The first exhaust port 40B has a plurality of through-holes formed in a hexagonal shape, and the plurality of through-holes 43 are arranged in the vertical direction (five in the fifth embodiment), and plural numbers are arranged in the left-right direction (in the present embodiment) Composition of each) The through hole 43 is formed in the rear surface 2p2 of the rear plate 2p, and is formed to penetrate in the orthogonal direction (almost orthogonal direction) with respect to the rear surface 2p2. That is, the through hole 43 from the first exhaust port 40B is formed, and the exhaust gas is inclined. The accommodating port 50B is included in the first vent port 40B and is placed on the left side of the through hole 43. The accommodating port 50B is sent to the first embodiment to be filtered. 4 3 is a square hole of 11

S -22 - 201216911 In the same manner, the accommodating port 5 0A is a path when the wire is wound or when the wire is pulled out, and the plug PG of the power wire 3 1 is housed in a state of being turned to the side. The second exhaust port 60B1 is located below the first exhaust port 40B, and is formed from the first exhaust port 40B in the left-right direction to the storage port 50B. Further, the second exhaust port 60B1 is formed integrally with the rear plate 2p of the cleaner body 2. Further, the second exhaust port 60B1 may be formed of another member similarly to the second exhaust port 60A of the first embodiment. Further, the second exhaust port 60 B1 has an elongated opening portion 68 (see Fig. 11) in the left-right direction, and a reinforcing rib 68s is formed in the opening portion 68 at intervals in the left-right direction. Further, the second exhaust port 60B1 is formed such that the wall surface 68a of the upper wall thereof extends toward the inside of the cleaner body 2 (the rear plate 2p), and the wall surface 68b constituting the lower wall faces the wall surface 68a. Further, the second exhaust port 6 0 B 1 forms the flow path R3 so as to be inclined upward with respect to the horizontal direction. Further, the length L10 of the wall surface 68a (see Fig. 12) is longer than the length L11 of the wall surface 68b. Further, the length L10 and the length L11 are the lengths from the inlet edge portion (inner side) of the exhaust gas to the outlet edge portion (outer side). Therefore, when the exhaust gas is discharged obliquely upward from the second exhaust port 60B1, that is, The Coanda effect is inclined more obliquely than the inclination of the wall surface 68a and the wall surface 68b, that is, in a state where the first exhaust port 4B side is further inclined, and is discharged from the flow path R3 of the second exhaust port 60B1. The second exhaust port 60B2 is located above the first exhaust port 40B, and is formed to be elongated from the first exhaust port 40B to the storage port 50B in the left-right direction. That is, the second exhaust port 60B2 is configured to be the second exhaust port 60B1.

S -23- 201216911 The first exhaust port 40B including the storage port 5 OB is sandwiched between the upper and lower sides. Further, the second exhaust port 60B2 is formed such that the wall surface 69a constituting the upper wall thereof extends toward the inside of the cleaner body 2 (the rear plate 2p), and the wall surface 69b constituting the lower wall is formed with respect to the wall surface 69a. Further, the second exhaust port 60B2 is formed on the rear surface 2p2, and is formed in an inclined rearward direction with respect to the horizontal direction. Further, the length L13 of the wall surface 69b is longer than the length L12 of the wall surface 69a. Further, the length L12 and the length L13 mean the length from the inlet edge portion (inner side) of the exhaust gas to the outlet edge portion (outer side). Therefore, when the exhaust gas is discharged obliquely upward from the second exhaust port 60B2, the so-called Coanda effect is inclined smaller than the inclination of the wall surface 69a and the wall surface 69b, that is, on the side of the first exhaust port 40B. The inclined state is discharged from the flow path R4 of the second exhaust port 60B2. In the rear surface 2pl of the rear plate 2p between the first exhaust port 40B and the second exhaust port 60B1, a support portion T2 that abuts against the ground when the riser main body 2 is housed is formed. In the vacuum cleaner 1B of the embodiment, the length L10 of the wall surface 68a of the exhaust gas from the first exhaust port 40B is larger than the flow path forming the second exhaust port 60B1 in the wall surface of the flow path forming the second exhaust port 60B1. Among the wall surfaces, the length L11 of the wall surface 68b facing the near wall is longer, so that the exhaust gas from the second exhaust port 60B1 is inclined toward the exhaust side from the first exhaust port 40B. The status is discharged. In the second embodiment, the length of the wall surface 69b of the exhaust gas from the first exhaust port 40B is close to the length of the wall surface 69b of the exhaust gas from the first exhaust port 60B2. (2) The wall surface of the flow path of the exhaust port 60B2 is formed longer than the length L12 of the wall surface 69a facing the near wall, so that the exhaust gas from the second exhaust port 60B2 is directed toward the first exhaust gas. The state in which the exhaust side of the port 40B is inclined is discharged. However, since the through hole 43 formed in the rear plate 2p is formed by a hole in the thin plate, the exhaust gas may be diffused and discharged when flowing out of the through hole 43. According to the second embodiment, even when the exhaust gas from the first exhaust port 40B is diffused and discharged, the exhaust gas from the second exhaust port 60B1 and the exhaust gas from the second exhaust port 60B2 may be exhausted. The exhaust gas from the first exhaust port 40B is prevented from being diffused to form the upward flow of the exhaust gas, whereby the flow of the exhaust gas can suppress the winding of the dust. In the second embodiment, the openings 6 8 and 6 9 of the second exhaust ports 60B1 and 60B2 are not oriented upward, but are set to be inclined upward with respect to the horizontal direction. Therefore, it is possible to suppress liquid or dust. Intrusion of foreign bodies. Further, in the second embodiment, since the exhaust gas from the second exhaust ports 60B1 and 60B2 is set to be inclined upward, the exhaust gas can be prevented from coming into contact with the user's clothes or face, and the user's absence can be prevented. comfortability. In the second embodiment, when the second exhaust port 60B1 is positioned for storage, when the cleaner body 2 is raised, it is located more forward than the line (dashed line) connecting the contact portion T2 of the support portion T2 and the ground of the wheel W (dashed line). (above in the upright state) (refer to FIG. 12), even if the second exhaust port 60B1 '60B2 is provided, it is not necessary to move the position of the wheel W of the cleaner body 2 rearward, so the cleaner body 2 does not become large. Chemical.

In the second embodiment, the second exhaust ports 60B1 and 60B2 are formed so as to overlap the storage port 50B of the power supply line 31 in the vertical position. Therefore, even if the storage port 5 0 B is In the side surface (horizontal direction), the exhaust gas from the second exhaust ports 60B1 and 60B2 and the exhaust gas from the storage port 50B can be dried and sandwiched to form an exhaust gas that is inclined upward as a whole. Therefore, it is possible to suppress the dust from being scattered on the floor due to the exhaust gas from the storage port 50B of the outlet of the cooling air (exhaust gas) serving as the power source line 31. In the second embodiment, the second exhaust port 60B 1 is formed in the middle of the exhaust flow path R1 from the discharge port of the electric blower 20B to the first exhaust port 40B, and the second exhaust port 6 OB1 is formed. Since the upper wall surface 68a of the flow path is formed to protrude into the flow path of the exhaust gas flow path R1 which is the inside of the cleaner body 2, the flow path of the exhaust flow path R1 is narrowed in the portion of the second exhaust port 60B1. The exhaust gas easily flows out from the second exhaust port 60B1, and the exhaust gas in a state where the flow velocity is high can be discharged from the second exhaust port 60B1, and the exhaust gas from the first exhaust port 40B can be prevented from being diffused. (Third Embodiment) Fig. 13 is a perspective view showing the appearance of a vacuum cleaner according to a third embodiment, and Fig. 14 is a longitudinal sectional view of the cleaner shown in Fig. 13. In the vacuum cleaner 1C of the third embodiment, the first exhaust port 40C and the second exhaust port 60C are provided in the rear portion of the cleaner body 2. Further, the first exhaust port 40C has a wider opening area than the first exhaust port 40B of the second embodiment. Further, similarly to the above-described electric blower 20A, the electric blower 20C supports the motor casing 21 by the outer casing 22, and discharges the exhaust gas via the discharge port 22a formed at the bottom of the outer casing -26-201216911. In other words, the first exhaust port 40C is composed of a plurality of through holes 44 arranged in the vertical direction and the horizontal direction, and the power supply line 3 1 is provided on the left side of the first exhaust port 40 C composed of the through holes 44. Storage port 5 0 C. Similarly to the above-described storage ports 50A and 50B, the accommodating port 50C is opened rearward in the horizontal direction, and the plug P G is housed toward the side surface. The second exhaust port 60C is disposed at an upper portion of the first exhaust port 40 C including the storage port 50C, and has an elongated opening 71 in the left-right direction, and a reinforcing rib that is spaced apart in the left-right direction is formed in the opening 71 7 1 s. The second exhaust port 60C is set to be inclined upward toward the rear (see Fig. 14). Further, a rear portion of the cleaner body 2 is formed with a support portion T3 that abuts against the ground when the cleaner body 2 is erected on the lower side of the first exhaust port 40C. In the third embodiment, the exhaust gas from the first exhaust port 40C is discharged toward the upper exhaust, and the exhaust of the second exhaust port 60C prevents the above-described diffusion, thereby forming the flow of the exhaust gas in the upward direction. And the flow direction of the exhaust gas is integrated, so that the dust can be suppressed from being rolled up. Further, in the third embodiment, since the opening portion 71 of the second exhaust port 60C is not oriented upward, and is set to be inclined upward, it is possible to prevent the exhaust gas from coming into contact with the user's clothes or face. It can prevent user discomfort. In addition, when the second exhaust port 60C is housed, when the cleaner body 2 is raised, it is located in front of a straight line (dashed line) that is closer to the contact point Q3 of the ground between the support portion T3 and the wheel W (in the vertical direction) Since the position of the upper side of the state (refer to FIG. 14) is not necessary, the position of the wheel W of the cleaner body 2-27-201216911 is not moved, so that the cleaner body 2 does not enlarge. In addition, in the third embodiment, the second exhaust port 60C is extended to a position that overlaps the storage port 50C of the power source line 31. Therefore, even if the storage port 50C is disposed on the side surface (horizontal direction), The exhaust gas from the second exhaust port 610C and the exhaust gas from the accommodating port 50C are dried to form an exhaust gas that is aligned in a uniform upward direction. Therefore, it is possible to suppress the dust from the ground from the exhaust port 5 〇C from the outlet of the cooling air (exhaust) of the power source line 3 1 . In addition, in each of the above-described embodiments, the first exhaust port and the second exhaust port are arranged in a vertical relationship as an example. However, the present invention is not limited to such a relationship, and may be arranged on the left and right.
