DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electric vacuum cleaner having a main part of a vacuum cleaner.

[0002]

2. Description of the Related Art As a prior art of the present invention, there is, for example, Japanese Patent Application Laid-Open No. 1-212523. In this case, a vacuum cleaner component (for example, a suction port for a gap) is supported by a concave portion provided in the wheel mounting base 9 shown in FIGS. 2 and 4.

[0003]

However, in the prior art, since the cleaner parts are supported by the wheel mounting base provided at the lower part of the cleaner body, when removing the parts, The user had to bend down, which was inconvenient to use. On the other hand, if the cleaner main body is provided with a cleaner component support portion, the main components such as the electric blower are installed inside the cleaner main body. The machine itself becomes larger. The present invention has been made in view of such a drawback,
It is an object of the present invention to provide a vacuum cleaner component support portion in which a vacuum cleaner component can be easily removed, and the vacuum cleaner body is not particularly large.

[0004]

SUMMARY OF THE INVENTION The present invention provides a dust container,
A filter device housed in the dust container, a filter support member that is mounted on an upper opening edge of the dust container and is made of an elastic material that supports the filter device, and is mounted on the filter support member. A cleaner main body having a built-in electric blower, wherein an exhaust port for exhausting the exhaust of the electric blower is formed on a side surface of the cleaner main body, and the exhaust port is formed at a position above the exhaust port of the cleaner main body. The vacuum cleaner component supporting portion is formed so as to protrude outward from the side surface of the cleaner main body, and the cleaner component supporting portion covers the upper side and the lateral side of the exhaust port.

[0005]

According to the vacuum cleaner of the present invention, a filter support member made of an elastic material for supporting the filter device is placed on the upper opening edge of the dust collecting container, and the cleaner main body is placed on the upper surface of the support member. Since the elastic member acts as a cushioning material, the elastic member absorbs a load applied to the cleaner component support portion provided integrally with the cleaner body, thereby preventing the cleaner component support portion from being damaged. Further, since the exhaust port is provided on the lower surface of the vacuum cleaner component support portion, the exhaust port does not appear in the external appearance, and the exhaust itself is not exhausted upward, so that the user is less likely to be directly exhausted.

DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described with reference to the drawings. 1 to 3 show an electric vacuum cleaner 2 according to the present embodiment.
Is provided with an intake port 3 and an exhaust port 4, and the flow of air is indicated by an arrow a in FIG.
Reference numeral 5 denotes a fan provided for cooling the electric blower 2, which is provided coaxially with a rotor (not shown) of the electric blower 2, and the flow of the cooling air is indicated by an arrow B in FIG. . Reference numeral 6 denotes a handle, which is fixed to the upper portion of the cleaner body 1 by screws. 1, 3, 4, and 8,
Reference numeral 7 denotes a vacuum cleaner component support portion which holds a suction port 8 for a gap and a round brush 9 and also has a support section 12 for a stand for storing the hose 10 and an extension pipe 11 attached thereto. A mounting portion 13, a round brush mounting portion 14, and a power cord support portion 15a are respectively formed on the mounting portion 13, and are integrally formed with the lower case 15 of the cleaner body 1. Reference numeral 16 denotes a float support portion provided on the upstream side of the suction port 3 of the cleaner body 1, and has a structure in which a float 17 is slidably supported up and down inside.

In FIGS. 1, 2 and 5, reference numeral 18 denotes a filter device which is formed in a bottomed cylindrical shape as a whole.
The bottom of this filter device 18 is
And a water-permeable material (RB-93-74 manufactured by Toyobo Co., Ltd. and has a laminated structure of two layers as shown in FIG. 9). On the other hand, the side surface is a water-impervious filter 20 made of a water-impervious material (RB-9 manufactured by Toyobo Co., Ltd.).
As shown in FIG. 10, the laminated structure has four layers. ). 4 and 5
In the figure, 21 is a resin support frame provided in a ring shape on the upper edge of the filter device 18, and 22 is the support frame 21.
Is a buffer frame (filter support member) which is formed by covering the upper and lower portions and the outer peripheral portion with an elastic material (soft embi). Reference numeral 23 denotes a prefilter provided on the upstream side of the filter device 18, and relatively large dust such as paper waste is filtered by the prefilter 23.

In FIGS. 1 and 2, reference numeral 24 denotes a dust collecting container, which is provided with a hose insertion port 25 for mounting the hose 10 on a side surface, and a rotatable caster 26 on the bottom surface as shown in FIG. Are provided in total. As shown in FIGS. 1, 2 and 7, the caster 26 has a screw insertion hole 27 formed in the bottom surface of the dust container 24.
The screw 28 is further inserted and screwed and fixed to the caster fixing member 30 through the elastic material sealing plate 29. This fixation prevents the liquid accumulated in the dust container 24 from leaking from the screw insertion hole 27 and prevents the liquid from directly touching the screw 28, thereby preventing corrosion of the screw 28 and the like. Can be. In FIG. 1, reference numeral 31 denotes the hose insertion port 25.
A wind direction change plate provided to prevent the air containing dust and liquid, etc., which has been sucked in directly from hitting the filter device 18 to prevent the filter device 18 from being damaged. Is provided.

2 and 8, reference numeral 33 denotes a clamp device for connecting the cleaner main body 1 and the dust collecting container 24, and a pair of clamp devices are provided on the left and right sides of the cleaner main body 1. In FIG. 8, reference numeral 34 denotes a power switch provided on the upper surface of the cleaner body 1.

Since the vacuum cleaner of this embodiment is constructed as described above, the vacuum cleaner component supporting portion integrally formed in the lower case of the vacuum cleaner main body has a buffer frame (filter supporting member) formed of an elastic material. ), So that even if a large force is applied when attaching / detaching the component to / from the vacuum cleaner component support, the buffer frame (filter support member) absorbs the force. As a result, the vacuum cleaner component supporting member is not damaged. Further, when the vacuum cleaner is moved during cleaning, even if the whole vacuum cleaner vibrates up and down due to unevenness of the floor surface, the buffer frame (filter support member) absorbs the vibration.

[0011]

According to the present invention, since the cleaner component supporting portion is placed on the dust collecting container via the filter supporting member, even if a large force is applied to the cleaner component supporting portion, the cleaner component supporting portion is removed from the elastic material. The filter support member absorbs this force and prevents damage to the vacuum cleaner component support. Also, vertical vibrations received during the movement of the vacuum cleaner are absorbed by this filter support member, so that vibrations are less likely to be transmitted to the clearance suction port and the round brush supported by the vacuum cleaner component support portion, and these may fall off. Absent. Furthermore, since the exhaust port is provided on the lower surface of the vacuum cleaner component support portion, the exhaust port does not appear in appearance and is excellent in design, and the air exhausted from the exhaust port does not go upward. In addition, it is possible to configure an electric vacuum cleaner in which exhaust air does not directly hit the user of the electric vacuum cleaner.
