Description

  The present invention is applied to the vacuum cleaner that can capture dust contained in the air sucked into the main body from the suction port, and the vacuum cleaner, and allows the dust to flow into the main body. The present invention relates to a check valve for a vacuum cleaner for preventing dust trapped in the body from flowing out.

  As a general vacuum cleaner, it has a main body with an electric blower, a suction tool that moves along the floor, and a connection hose that connects the suction tool to the main body. Some of them can be fitted with a dust collecting filter. When this type of vacuum cleaner is operated, the outside of the machine (air on the floor) is sucked from the suction tool by the driving of the electric blower provided in the body, and the air passes through the connection hose to the body. It is sucked into the main body from the suction port formed in the. A dust collection chamber communicating with the suction port is formed in the main body, and a dust collection filter is disposed in the dust collection chamber. Dust contained in the air sucked from the suction port is captured by the dust collecting filter when the air passes through the dust collecting chamber. The air after the dust is captured by the dust collecting filter is exhausted from, for example, an exhaust hole formed on the rear surface (surface opposite to the suction port) that defines the outer shape of the main body (for example, Patent Document 1). reference).

  The main body can be accommodated in a state where a power cord for supplying power to the main body is wound. The power cord is used in a state where at least a part of the power cord is housed in the main body unless it is used in a state where the power cord is pulled out from the main body. Since the power cord generates heat during use (when energized), if the vacuum cleaner is operated with at least a portion of the power cord housed in the main unit, The area where the cord is located (the cord storage room) becomes hot. Therefore, in the configuration disclosed in Patent Document 1, a part of the air after being sucked into the main body and trapped with dust is exhausted from the exhaust hole through the code storage chamber, thereby Can be cooled.

  However, in the above configuration, since hot air is directly exhausted from the cord storage chamber through the exhaust hole, the user may feel uncomfortable. Therefore, a configuration is possible in which hot air in the cord storage chamber is exhausted from the entrance and exit of the power cord without providing an exhaust hole in the portion facing the cord storage chamber. By exhausting, the user may feel uncomfortable.

In addition, in a conventional vacuum cleaner, if dust accumulates to some extent in the dust collection filter, the outer surface of the dust collection filter sticks to the inner surface of the dust collection chamber, blocking the flow path of air flowing out of the dust collection chamber. In some cases, the suction power of the vacuum cleaner was weakened.
In the electric vacuum cleaner disclosed in Patent Document 1, handles for gripping when lifting the main body are attached to both ends of the handle so as to be rotatable with respect to the housing of the main body. FIG. 9 and FIG. 10 are side views of conventional vacuum cleaner main bodies 3A and 3B for explaining the structure of the handles 123 and 223 of this type. The vacuum cleaner main bodies 3A and 3B have an outer shape defined by the housing 11, and suck air into the housing from a suction port 12 formed on the front surface of the housing 11 to capture dust contained in the air. Can do. The handles 123 and 223 have a substantially arc shape, and both end portions thereof are rotatably attached to the upper portion of the housing 11. These types of handles 123 and 223 are accommodated in a state flush with the outer surface of the housing 11 when not in use (accommodated state; see FIGS. 9A and 10A). It is turned into a grippable state (a grippable state; see FIGS. 9B and 10B). However, when the handles 123 and 223 are rotated, the arc-shaped locus drawn by the corners on the housing 11 side (lower side) at both ends of the handles 123 and 223 interferes with the housing 11. Accordingly, as shown in the example shown in FIG. 9, the housing 11 is provided with a recess 27 for allowing the corner to pass therethrough, or as shown in FIG. 28, it is possible to prevent the handles 123 and 223 from interfering with the housing 11. However, in the case of the configuration as shown in FIG. 9, the shape of the housing 11 is complicated, and in the configuration as shown in FIG. 10, the housing when the handle 223 is in the accommodated state by cutting off the corners. The sense of unity with 11 is lost.

The present invention has been made under such a background, and an object of the present invention is not to form a recess for avoiding interference of the handle in the housing, and it is a part of the housing with the handle in the accommodated state. The object is to provide a vacuum cleaner that does not lose its bodily sensation.

In order to achieve the above object, the invention according to claim 1 is a housing (11) that defines the outer shape of the main body (3), and a housing state in which both ends are rotatably attached to the housing and are close to the housing. And a handle (23) that can be rotated between the accommodated state and the graspable state, and formed on the outer surface of the housing, and when the handle is in the accommodated state, A step (24) adjacent to the handle so that the handle is flush with an outer surface of the housing, the step being rotated between the housed state and the grippable state of the handle In this case, the electric vacuum cleaner is characterized by extending substantially along the tangential direction of the substantially arcuate locus drawn by the corners (23C) on the stepped portion side at both ends of the handle .

  According to this configuration, when the handle is rotated between the accommodated state and the grippable state, the corners on the step side at both ends of the handle are within the space opposite to the housing with respect to the step. Because it draws a substantially arc-shaped trajectory, the handle (end part) of the housing (the step part) can be used without forming a recess in the housing to avoid interference with the handle or by cutting the corners into a curved part. Does not interfere with. Therefore, it is not necessary to form a recess for avoiding interference with the handle in the housing, and the sense of unity with the housing when the handle is in the accommodated state is not lost.

  In this embodiment, by supporting the dust collection filter 7 (filter part 7B) from below by the lower rib 69, a space can be formed between the inner bottom surface of the dust collection chamber 13 and the dust collection filter 7. By supporting the dust collection filter 7 (filter part 7B) from the rear side by the rear rib 70, a space can be formed between the partition wall 57 and the dust collection filter 7. This prevents the outer surface of the dust collection filter 7 (filter part 7B) from sticking to the inner bottom surface of the dust collection chamber 13 or the partition wall 57 even when dust is accumulated in the dust collection filter 7 to some extent. Therefore, the air flow path can be secured, so that the flow path of the air flowing out from the dust collecting chamber 13 can be prevented from being blocked.

In particular, since the lower rib 69 and the rear rib 70 formed so as to extend in the same plane can form a flow path communicating from the bottom of the dust collection chamber 13 to the opening 58, the dust collection chamber 13 further Air can flow out well.
However, the configuration is not limited to the configuration in which the lower rib 69 and the rear rib 70 are both formed in the dust collecting chamber 13, and the configuration in which one of the lower rib 69 or the rear rib 70 is formed may be used. Good.

FIG. 21 is a rear view of the main body 3 with the upper housing 11A removed. FIG. 22 is a cross-sectional view taken along the arrow BB shown in FIG. 21, in which the blower unit 56 is omitted.
A substantially annular front mounting portion 71 formed of an elastic body such as rubber is attached to the front end edge of the blower cover 55, and a rear view formed of an elastic body such as rubber is attached to the rear surface of the blower cover 55. A substantially rectangular rear mounting portion 72 is mounted (see FIGS. 18 and 19). When the blower unit 56 is disposed at a predetermined position (blower housing chamber 54) in the housing 11, the front mounting portion 71 is supported from below by a support rib 73 protruding upward from the front end portion of the inner bottom surface of the blower housing chamber 54. At the same time, the rear mounting portion 72 is supported from below by a support rib 74 protruding upward from the rear end portion of the inner bottom surface of the blower housing chamber 54 (FIGS. 18, 19, 21 and 21). (See FIG. 22). In this way, by supporting the blower unit 56 via the elastic body, it is possible to suppress the vibration generated by the drive of the electric blower 2 from being transmitted to the housing 11.

  A recess 75 that is recessed from the outside toward the inside is formed in the vicinity of the position where the support rib 74 is formed at the bottom rear end of the lower housing 11B. By forming the recess 75, a vertical surface 75A that rises almost vertically upward on the inner bottom surface of the blower housing chamber 54, and a horizontal surface 75B that extends substantially horizontally rearward from the upper end of the vertical surface 75A, And the inner bottom surface is raised (see FIG. 22). The support rib 74 is formed so as to protrude upward from the horizontal plane 75B.

  The support rib 74 has a flat plate portion 74A along a vertical plane extending in the left-right direction, and bent portions 74B that are bent rearward from left and right end edges of the flat plate portion 74A. The flat plate portion 74 </ b> A is formed with a substantially rectangular recess 76 corresponding to the lower portion of the rear mounting portion 72 of the blower unit 56, and the lower portion of the rear mounting portion 72 can be fitted and supported in the concave portion 76. It can be done. That is, the rear mounting portion 72 of the blower unit 56 is supported by the bottom surface of the recessed portion 76 of the support rib 74 and is sandwiched in the left and right directions by the arms 77 formed on the left and right sides of the recessed portion 76, so that the displacement in the left and right direction is reduced. It is regulated (see FIG. 21). By forming the bent portions 74B at the left and right end edges of the flat plate portion 74A of the support rib 74, both the arms 77 can be made difficult to bend in the left-right direction, so that the electric blower 2 can be more firmly fixed.

In this embodiment, since the inner bottom surface of the lower housing 11B is raised by the depression 75 formed in the lower housing 11B, and the support rib 74 is formed in the raised portion, the length of the support rib 74 in the vertical direction is increased. The length can be shortened. Therefore, the strength of the support rib 74 can be improved, and the electric blower 2 can be more firmly fixed.
FIG. 23 is a perspective view of the air blowing unit 56 as viewed from the upper left side.

  Referring to FIG. 23, the blower cover 55 of the blower unit 56 is formed with a flat surface 78 extending substantially in the horizontal direction at the upper end portion of the rear portion thereof, and the electric vacuum cleaner is formed on the flat surface 78. A substrate 79 including a control circuit for controlling the operation is attached. At the right end portion of the substrate 79, a heat radiating plate 80 that is hot during operation of the vacuum cleaner is disposed. A plurality of wirings 81 for electrically connecting various components provided in the vacuum cleaner to the substrate 79 are attached to the substrate 79.

  A fixing rib 82 for fixing at least one of the plurality of wires 81 is formed on the blower cover 55 so as to protrude upward from the left front end portion of the flat surface 78. A groove 82A extending downward is formed at the leading edge of the fixing rib 82, and the wiring 81 can be fixed by sandwiching the wiring 81 in the groove 82A. As shown in FIG. 23, if other wires 81 are passed through the space between the wires 81 fixed to the fixing rib 82 and the outer surface of the blower cover 55, fixing for fixing these other wires 81 is performed. Since these other wirings 81 can be processed (bundled) without separately providing ribs, the structure can be simplified.

FIG. 24 is a plan view of the blower unit 56.
As shown in FIG. 24, if soundproofing materials 83 and 84 are wound around the outer peripheral surface of the blower cover 55, the drive sound of the electric blower 2 can be made difficult to leak outside. The soundproof material is formed of felt having relatively poor air permeability, covers at least the outer peripheral surface of the blower cover 2 where the substrate 79 is disposed, and has an opening 83A formed in a portion facing the heat sink 80. A soundproofing material 83 and a urethane soundproofing material 84 that is formed of urethane having relatively good air permeability and faces the heat radiating plate 80 so as to cover the opening 83A of the felt soundproofing material 83 are included.

According to such a configuration, the outer peripheral surface of the blower cover 55 can be mainly covered with the felt soundproofing material 83 to enhance the soundproofing effect, and the heat radiating plate 80 that becomes high temperature during the operation of the vacuum cleaner has air permeability. By covering with a relatively good urethane soundproof material 84, the heat radiated from the heat radiating plate 80 can be released to the outside satisfactorily.
In this case, if the surface of the urethane soundproof material 84 facing the heat radiating plate 80 is formed in a corrugated shape (a shape having a plurality of convex portions and concave portions), it is formed between the concave portion of the urethane soundproof material 84 and the heat radiating plate 80. Through this space, the heat radiated from the heat radiating plate 80 can be well guided to the outside.

However, the configuration is not limited to the configuration in which the opening 83A of the felt soundproof material 83 is covered with the urethane soundproof material 84, and the urethane soundproof material 84 is omitted, and the heat radiated from the heat radiating plate 80 is formed in the felt soundproof material 83. It may be configured such that it can escape from the opening 83A to the outside.
FIG. 25 is a cross-sectional view of the main body 3 of the electric vacuum cleaner as viewed from the right side when the main body 3 is cut along a vertical plane extending in the front-rear direction on the right side of the reel unit 68. FIG. 26 is a right side view of the reel unit 68.

There is a cord storage chamber 64 formed inside the compartment. A plurality of vent holes 86 for allowing air to flow from the blower housing chamber 54 into the cord housing chamber 64 are formed in the side plate 67A so as to open in the left-right direction. A plurality of exhaust holes 87 for exhausting the air that has flowed into the cord housing chamber 64 from the inside of the cord housing chamber 64 are formed in the peripheral surface plate 67B so as to open in the front-rear direction (FIG. 4, FIG. 19 and FIG. 21). The rear surface of the housing 11 faces the rear side of the reel supporter 67.

  In this embodiment, the dust trapped in the dust collecting chamber 13 and the air flowing into the blower housing chamber 54 is caused to flow into the cord housing chamber 64 from the vent hole 86 formed in the side plate 67A of the reel supporter 67, and the reel By evacuating from the exhaust hole 87 formed in the peripheral surface plate 67B of the supporter 67, the cord accommodating chamber 64 (power cord) can be cooled through the cord accommodating chamber 64. In this case, air (hot air) that has passed through the cord storage chamber 64 passes through the exhaust holes 87 formed in the peripheral surface plate 67 </ b> B that partitions the cord storage chamber 64, and exhausts from the exhaust holes 18 formed in the rear surface of the housing 11. Is done. Therefore, the user does not feel uncomfortable as in the configuration in which hot air is directly exhausted from the exhaust hole 18 of the housing 11, and the user may feel uncomfortable as in the configuration in which hot air is exhausted from the cord doorway 20. Therefore, the exhaust from the vacuum cleaner body 3 can be performed more suitably.

  Further, in this embodiment, as shown in FIG. 4, the plurality of exhaust holes 87 formed on the peripheral surface plate 67 </ b> B of the reel supporter 67 are positioned so as not to face the plurality of exhaust holes 18 formed on the rear surface of the housing 11.
