In the figure, 101 is a vacuum cleaner main body with built-in electric blower chamber on the front dust collecting chamber 102, the rear. This dust collecting chamber 102 attach the dust bag, covered freely opened and closed by the dust collecting chamber lid 105 is in its upper opening. The electric blower chamber coordinated electric feed air blower for sucking dust into the dust collecting chamber 102, specifically, Gorge lifting by the lower case 107 and upper case 108 constituting the cleaner body 101 fixed are doing. Reference numeral 109 denotes an exhaust port provided at the rear of the electric blower room, and is formed in the upper case 108. A removable frame member 111 is provided at the exhaust port 109, and the entire surface of the frame member 111 is covered with a spinning cloth 110 and fixed by welding.
[0004]
A fine dust filter 112 is detachably provided on the frame member 111 on the exhaust upstream side. Further, a fixing member 113 which is fastened and held to the upper case 108 with a screw or the like is provided at an upper portion of the frame member 111, and a lower portion of the frame member 111 has an engagement portion 114 provided at a lower end thereof, The frame member 111 is held by the engagement with the engaged portion 115 provided at the lower edge portion of the frame member 111. Further, a recess a (gap) 116 is provided near the engaging portion 114 so that a tool, a coin, or the like can be inserted.

The exhaust port 109 is We covered the entire surface of the spinning cloth 110. Further, since the hole diameter of the exhaust holes (the eyes of the spun cloth) is small because of the spun cloth 110, the exhaust air from the exhaust ports 109 has a smaller exhaust flow rate from the individual exhaust holes because the hole diameter is small. In addition, since the exhaust gas flow from the exhaust holes is small, the exhaust gas diffuses to the adjacent exhaust holes, and the exhaust gas that has passed through the exhaust passage inside the main body 101 is uniformly dispersed throughout the exhaust port 109 and is discharged to the atmosphere. By being discharged into the interior, soft exhaust air can be exhausted, thereby preventing dust from being blown away during cleaning and eliminating discomfort.
[0007]
[Problems to be solved by the invention]
However, in the above-mentioned conventional vacuum cleaner, the spinning cloth 110 at the exhaust port 109 cannot be collected by the vacuum cleaner during use of the vacuum cleaner, and the dust passes through the spinning cloth 110 at the exhaust port 109 and the spinning cloth. Static electricity is generated in the spinning cloth 110 due to friction with the cloth 110. After use, the exhaust port 109 is usually stored in contact with the surface to be cleaned, but dust on the surface to be cleaned adheres to the spinning cloth 110 at the exhaust port due to static electricity generated in the spinning cloth 110. I do. Then, the dust adhering to the spinning cloth 101 is blown into the room together with the exhaust air when the cleaning is performed again, and has a problem of floating in the room.
[0008]

It can be suppressed. Further, the same effect can be exerted even if the spun cloth is washed again with water when it becomes dirty and left in a wet state.
[0012]
【Example】
One embodiment of the present invention will be described with reference to FIGS.
[0013]
In FIG. 1, reference numeral 1 denotes a cleaner main body having a dust collecting chamber 2 at a front portion and an electric blower room 3 at a rear portion. A dust collecting bag 4 is mounted in the dust collecting chamber 2, and an upper opening thereof is covered with a dust collecting chamber lid 5 so as to be openable and closable. An electric blower 6 for sucking dust is disposed in the dust collecting chamber 2 in the electric blower chamber 3. Specifically, the electric blower 6 is sandwiched and fixed between the lower case 7 and the upper case 8 constituting the cleaner main body 1. are doing. Reference numeral 9 denotes an exhaust port provided at the rear of the electric blower room, and is formed in the upper case 8.
[0014]
A removable frame member 11 is provided in the exhaust port 9, and the entire surface of the frame member 11 is covered with a spun cloth 10 coated with a metal such as aluminum by sputtering, and is fixed by welding. The frame member 11 is provided with a fine dust filter 12 detachably on the exhaust upstream side. Further, a fixing member 13 that is fastened and held to the upper case 8 with screws or the like is provided on an upper portion of the frame member 11, and the upper portion of the frame member 11 is sandwiched between the fixing member 13 and the upper case 8. . On the other hand, the lower portion of the frame member 11 holds the frame member 11 by engaging the engaging portion 14 provided at the lower end portion with the engaged portion 15 provided at the lower edge of the exhaust port 9. I have. Further, a concave portion a (gap) 16 into which a tool, a coin, or the like can be inserted is provided near the engaging portion 14. The concave portion a16 may be formed by denting the upper case 8 or may be formed by expanding the frame member 11.
[0015]
Regarding the attachment / detachment configuration of the frame member 11, it can be easily presumed that, in addition to the above attachment / holding configuration, the upper and / or lower portions may be replaced by a hinge configuration.
[0016]
The operation of the above configuration is as follows.
[0017]
The spinning cloth 10 does not generate static electricity due to the antistatic treatment, dust and the like do not adhere to the spinning cloth 10 at the exhaust port 9, and clean exhaust air discharged from the spinning cloth 10 is released into the atmosphere. The wind makes it possible to clean comfortably without dust floating inside the room.
[0018]
Exhaust holes 17 formed by the spinning cloth 10 provided in the exhaust port 9 each have a smaller area than the exhaust holes formed in the conventional outer resin molded part, and the spun cloth 10 coated with metal by sputtering. Therefore, the number of the exhaust holes 17 (the eyes of a spun cloth coated with metal by sputtering) can be more than doubled in the same exhaust port 9 region as in the related art. Therefore, the following effects can be obtained by passing the exhaust gas discharged during the cleaning operation through the spun cloth 10 coated with metal by sputtering. The exhaust flow rate from each exhaust hole 17 can be reduced because the hole diameter is small. At the same time, since the exhaust flow rate from the exhaust holes 17 is small, the exhaust gas diffuses to the adjacent exhaust holes 17, and the exhaust gas that has passed through the exhaust passage inside the main body is uniformly dispersed throughout the exhaust port 9 and is discharged to the atmosphere. It is discharged into the inside, so that the soft exhaust air can be exhausted, the blowing of dust during cleaning is suppressed, and the exhaust air does not hit the feet and discomfort is eliminated. Further, as described above, when the total number of the exhaust holes 17 is equal to that of the conventional one, the area of the exhaust port 9 region is smaller than that of the conventional one. Exhaust gas is emitted, and the sound insulation effect of the outer shell of the main body can be increased, so that the noise value can be reduced.
[0019]
As for the attachment of the frame member 11, the upper part of the frame member 11 is inserted between the upper case 8 and the fixing member 13, and the lower part of the frame member 11 is pushed in from behind, so that the engagement portion 14 Can be easily fixed to the engaged portion 15 of the exhaust port 9.
[0020]
As for the detachment, a tool or a coin is inserted into a concave portion a16 provided near the engaging portion 14, and the engaging portion 14 is removed by gouging, and the frame member 11 can be removed.
[0021]
Further, by disposing the frame member 11 covered with the spun cloth 10 coated with metal by sputtering at a position inserted inside the outer shell of the cleaner body 1, the outer shell can receive the exhaust pressure. This has the effect of preventing overhanging and arranging it at a position where it is less likely to be soiled.
[0022]
Next, regarding the fibrous material of the spun cloth 10 coated with metal by sputtering, when synthetic fibers are used, for example, when nylon is used, since heat resistance is high, it is generated by exhaust heat or contact with the floor surface. Thermal deformation due to frictional heat can be prevented, and the surface has good slipperiness, so the feel when touched by hand is smooth, and at the same time it is hard to catch on sharp protrusions, and The effect is obtained. When polyester is used, the structure can be made relatively inexpensively. Further, since the exhaust port is excellent in abrasion resistance, it may be effective when an exhaust port is formed in a place where the exhaust port easily contacts an object such as a floor surface or furniture. Here, nylon and polyester are taken as an example.For example, if the fabric is easily dyed or if antibacterial / antifungal or deodorant processing is required, use fibers suitable for each application. Needless to say, the use of synthetic fibers other than the above is also included.
[0023]
Furthermore, by applying antibacterial or antifungal processing to the spun cloth 10 coated with metal by sputtering, it is possible to improve the image of an unsanitary exhaust port of the product and to actually suppress the growth of bacteria. You can do it. Further, the same effect can be exerted even if the spun cloth is washed again with water when it becomes dirty and left in a wet state. In addition, the effect of suppressing the odor generated from the dust collected in the paper bag can be obtained by performing the deodorizing process. In addition, although it is used under conditions that make it easy to be stained by forming an external part, it is also possible to perform a silicon-based or fluorine-based water-repellent treatment for the purpose of making it difficult to adhere.
[0024]
Next, regarding the shape of the exhaust grid 21 of the frame member 11 forming the exhaust port 9, as shown in FIG. 3, a mold formed by combining straight lines (for example, a triangular shape) facilitates mold processing. 4, a circular shape having the highest priority on strength (not shown), a honeycomb shape in which the opening ratio of the exhaust port 9 and the strength are balanced as shown in FIG. Regarding the combination of multiple shapes, or the formation of completely irregular shapes, rib widths, and rib thicknesses, it is easy to understand that it should be formed in a suitable shape if necessary. It can be guessed. FIG. 6 shows a spun cloth in which a spun cloth 22 in which metal sputter is applied to a spun cloth to prevent static charge. Further, FIG. 7 shows that the spinning cloth 23 in which the surface of the spinning cloth is coated with a conductive polymer is used to prevent static electricity.
[0025]
As shown in FIGS. 5 and 8, a concave portion b18 is provided at a substantially central portion of the frame member 11 on the downstream side of the exhaust, and the concave portion b18 contains a gas-permeable elastic material 19 and a filter 20 to prevent static electricity. When the structure is sandwiched between the spinning cloth 10 and the elastic material 19 having air permeability, the antistatic spun cloth 10 can be provided with a cushioning property, and an effect as a kind of bumper can be obtained. This gives a soft feeling when touched by hand, and a good touch quality. Another effect can be obtained by using the filter 20. For example, by using the filter 20 having a lower fiber density than the antistatic spun cloth 10, the clearing effect of the exhaust air can be increased and the exhaust can be diffused. This leads to a silent effect at the same time. On the other hand, by using the filter 20 which is denser than the fiber density of the antistatic spun cloth 10, the dust collecting effect can be improved and the exhaust can be made cleaner.
[0026]
Here, the elastic material 19 is used in order to give the antistatic spun cloth 10 a cushioning property. However, it can be easily guessed that the antistatic spun cloth itself can be substituted by using an elastic material in advance. It is.
[0027]
【The invention's effect】
As described above, according to the present invention, dust and the like do not adhere to the spinning cloth, and the exhaust gas that has passed through the exhaust passage inside the main body is uniformly dispersed throughout the exhaust port covered with the antistatic spinning cloth. Clean exhaust air is released into the atmosphere with soft exhaust air to suppress dust blowing. Also, it is possible to reduce the noise level can increase the sound insulation effect by the body shell.
