因となっていた。The air flow near the air inlet 8a during the operation of the electric blower 8 is a swirling flow in the same direction as the rotation direction of the electric blower 8. In FIG. 5, as shown in FIG. 5, the grid 7 and the support ribs 7a provided for holding the filter 10 are installed in a direction orthogonal to the swirl flow, so that the formation of the swirl flow is hindered. This contributed to a reduction in the suction efficiency of the electric blower 8.

であった。In the example of Japanese Patent Application Laid-Open No. 9-75268, although the swirling flow is not hindered, the guide wings 37 have a thin cylindrical shape and project greatly into the dust collection chamber 24, so that the amount of dust collection is reduced. In addition to being a cause, the wing portion 38 is small as shown in FIG. 8, so that the swirling flow energy generated by the wing portion 38 is small, and the effect of the installation is low.

な空気の流れを形成することができる。The operation of the vacuum cleaner constructed as described above will be described. The fan 2c of the electric blower 2 used for the vacuum cleaner is set at 4 min.
It is rotated at a high speed of around 10,000 rotations. Further, the electric blower 2 uses air as a medium for sucking dust. However, even if the air has a relatively low viscosity, the air inflow port 2a is close to the fan 2c of 40,000 revolutions per minute due to its viscosity.
Before flowing into the electric blower 2 from the fan 2, a swirling flow (hereinafter referred to as a pre-swirl flow) is drawn in the same direction as the rotation of the fan 2c. Disturbing this pre-swirling flow not only causes a decrease in the flow velocity, but also increases the possibility of generating a turbulent flow in the vicinity of the air inlet 2a. , The suction loss increases due to the mechanism of lowering the suction efficiency and lowering the suction efficiency. By the way, since the swirling flow guide 5a in the embodiment of the present invention is provided in the same direction as the rotation direction of the fan 2c, and gradually changes from the tangential direction to the radially inner side, the air inlet 2a Air can flow smoothly into the air. Further, by providing a plurality of the swirling flow guides 5a and bringing the intake filter 6 into contact with the end surface thereof, the air is filtered so that the intake filter 6 is not pushed backward by the wind pressure of the intake air to cause rearward displacement. Since the same effect as that of the grid provided on the front surface of the inlet 2a can be obtained, the grid, which is one of the factors inhibiting the formation of the pre-swirling flow, can be eliminated. In addition, by providing the funnel 5b integrally with the swirling flow guide 5a, a smoother air flow can be created without increasing the number of parts. The height of the outer peripheral rib 5d is
Since the support rib 5c is set lower than the front end, the air inflow from the outer peripheral direction is facilitated, and the intake filter 6
More air can smoothly flow into the front surface. Further, since the rear end of the funnel 5b is shaped so as to be inscribed in the air inlet 2a, the position of the funnel 5b does not move with respect to the air inlet, and a stable and smooth air flow is formed. Can be.

Since a plurality of swirling flow guides which are arranged and gradually change from the tangential direction to the radially inner side in the same direction as the rotation direction of the fan are provided, the flow of air flowing into the air inlet of the electric blower is reduced. Not only can it be smooth, but even the air disturbed by various factors such as dust collection bags and intake filters before reaching the air inlet can be positively pre-swirled just before flowing into the air inlet. Further, it is possible to improve the suction efficiency of the electric blower and supply a vacuum cleaner having a high dust absorption performance.

繋がり、製品開発の効率も向上するものである。In the invention according to claim 2 of the present invention, a filter supporting rib for supporting the suction filter in contact with the front portion of the swirling flow guide is provided integrally, so that it corresponds to a conventional grid. The intake filter can be supported without providing a separate part or a separate component for supporting the filter, and as a result, in the configuration provided with the grid, the grid installed in the direction orthogonal to the pre-swirling flow Not only does loss occur due to the ribs and the support ribs, but also when the funnel cross-section approaches an ideal shape that gradually changes from the radial direction to the axial direction as it approaches the center, the gap between the funnel outer periphery and the lattice becomes narrower. In some cases, the actual intake area was reduced and the efficiency was improved, rather than reduced.However, according to the configuration of the present invention, the funnel shape could be made closer to the ideal directly. Lead to improvement of suction efficiency of electric blower, is intended to improve the efficiency of product development.

るものである。According to the invention of claim 3 of the present invention, by providing the funnel integrally with the swirling flow guide, not only a smoother air flow can be created without increasing the number of parts but also, The swirling flow guide and the funnel, which are considered to be insufficient in rigidity by themselves, serve as reinforcing members, thereby making it possible to reduce the thickness of the entire part, and as a result, it is possible to secure a wider flow area and reduce the weight of the entire part. Such effects as above also occur. In particular, when the present configuration is implemented in combination with the configuration described in claim 1, since the lattice portion can be eliminated, the effect of integration can be further improved, such as the mold configuration in resin molding can be greatly simplified. It will be even higher.

に拘わらず安定した吸引性能が得られるものである。In the invention according to claim 4 of the present invention, since the height of the outer peripheral rib is set lower than that of the supporting rib, air can easily flow in from the outer peripheral direction, and more air flows into the front surface of the intake filter. Air can flow in smoothly. Thus, in a vacuum cleaner of a type that uses a dust collection bag, even in a state where dust accumulated in the dust collection bag blocks the front part of the intake filter, the dust collection bag can be efficiently operated from the side of the dust collection bag with a relatively small accumulation amount. Therefore, stable suction performance can be obtained regardless of the amount of dust collection.

供給することができるものである。In the invention according to claim 5 of the present invention, the step at the boundary portion is made smaller by forming the rear end of the funnel so as to abut against the inner wall of the air inlet, and as a result, smooth air flow is achieved. In addition to being able to form a flow, the positional relationship between the funnel and the air inlet is because it is supported by an elastic material or there is play around the fixed part to ensure the radial positioning. This makes it possible to reduce the difference between individual units during assembly or the like as compared with the conventional configuration in which is unstable, and to supply a product with stable performance.
