Description of the Invention (1) Technical Field of the Invention The present invention relates to an electric dust collector, and in particular, relates to the use of an exhaust fan from an electric blower built into the body of a vacuum cleaner to the ground for use from a camp spot tube. Exhaust gas recirculation (circulation) type dust collectors that return the suction members and other components. Conventional technology j p Vacuum cleaners are generally moved on the ground, so that the exhaust air from the electric blower built in the vacuum cleaner is exhausted to the outside from the exhaust ports formed on the back side of the body. That is, the dust sucked together with the air from the floor suction member and the like is sucked into the body of the cleaner through a pipe and a hose. After removing the dust with a paper bag or the like, the motor of the electric blower is cooled and discharged from the exhaust port to the outside. The exhaust air from the electric blower 5 is all discharged to the outside. Therefore, the problem that the dust stagnate on the floor or the carpet is diffused into the room due to the exhaust wind is raised. In order to reduce such exhaust air to the outside or improve the dust collection effect, etc., study by yourself. It is known, for example, as disclosed in Shiko Sho 39-36553 or Japanese Patent Application Laid-Open No. 9-1 35 79.

In the formation, it is tied to the built-in electric delivery hose. The exhaust flow path of the exhaust gas return is formed: the body; the hose from the electric blower constitutes a double structure, a duster, which is characterized by .k # ， and the inner hose forming the suction flow path makes 4 \ 8080 five 'Explanation of the invention (3) Flexible soft camp with built-in conformal device, The outside hose is formed by the flexure without a conformal device. It is also characterized in that the outer hose uses a concave and convex telescopic dust j body. -The end is installed on the suction side of the tongue and the inside end of the hose that is used to attach the other end to the hose handle is attached to the outside. The end of the hose is more transparent than the outside hose. The inner hose is opaque, so that the outer side is soft. The connecting pipe consists of a suction-shaped portion that has an approximately circular cross-section and a portion formed into a body with the inner cylindrical portion. In addition, the exhaust flow path is formed by the second-shaped portion. The outer cylindrical part is formed.

The suction path 4 is used to make the flow path into :::::, pipe 2, connecting pipe 3, and the ground and exhaust flow path B, each of which is divided into a suction flow path A in structure A by Tian Jiji f Γ The dust collecting chamber 9 of the 5 body 1 or the lower side of the motor chamber 6 is shaped as M5. A part of the exhaust gas returning from the exhaust of the fan 5 is the exhaust gas flow ^ The air muscles and the hose insertion port 12 of the vacuum cleaner body 1 The exhaust flow path b of the joint portion 20 communicates. j Soft g joint part 20 structurally connects the tube 20a, the soup forms a concentric circle structure, forming the inside of the suction tube A, the connecting tube 2a ends at both ends, and the ends are inserted into the paper bag 7 The mounting portion 7 is connected to the exhaust gas flow path b on the side of the cleaner body 1 by using an external connection, = 2 0b /%.

One end of the double-structured hose is attached to the other ends of the coupling members 20a and 20b. This hose uses a layer of two-wire tube inside. It is a general electric (gathered as an opaque flexible hose 2a for dust collectors) with coils 21 that have g properties (because they are used as signal wires) and shape retention. Focusing on the inside of the inner hose 'a, the coil wire 21 is built in, and no coil wire is needed on the outside. A flexible hose 2b, which is the same as a drain hose for a washing machine, is used on the outside. The flexible hose 2b The coil wire 21 is built in like a layer of two-wire hose 2a. It is a light and thin flexible telescopic hose, which has the advantages of large tube surface area and good heat dissipation. In this embodiment, the guide hose 2b is translucent. Resin is formed. Therefore, 'the heavier one-layer two-wire hose 2a is used by the inner coil with a smaller diameter for the inner hose 2.' The light guide hose 2b is used for the outer hose with a larger diameter, and the double hose is used. 2 can greatly reduce weight.

Description of the invention (5) In addition, the guide hose 2b forming the outer side of the exhaust flow path B, such as a telescopic hose with a small unevenness, has a large surface area and a good looseness, which can suppress exhaust. Temperature rise of the outer surface of the double hose caused by air heat. Therefore, by controlling the temperature rise of the outer surface of the double soft official 'because the temperature does not rise to the extent that the user feels a strange feeling, the usability is improved. In addition, by making the inner one-layer second-line hose 2a opaque and making the outer guide hose 2b transparent, the appearance appeal of the design effect can be improved. Moreover, the heavy hose 2 is better than the ordinary hose It is thick, but because the outer guide hose "is translucent, you can see that the inner one-layer second-line hose 2 & becomes thinner. Also, because the inner one-layer second-line hose 2a is opaque to allow dust to pass through" Make the dust-free clean air pass through the outer guide tube 2b semi-transparent, no dust attached to the inner layer of the second-line hose 仏 can be seen, and the inner surface of the outer guide tube 2b is not polluted 'The appearance of the double hose 2 will not be damaged. In this soft part 2, the inner one-layer two-wire pipe 2a is screwed into the outer surface of the protruding end of the inner connecting pipe 20a to form a threaded rib 22 and is fixed. After that, the outer guide tube 2b is attached to the outer connection tube 20b and adhered. The installation portion of the hose 2 is covered with the cylindrical protective cover 23. As mentioned above, the one layer which is difficult to install on the inner side When the second-line hose 2a is installed on the inner connecting pipe 20a, it is because of its hose installation The hose installation end of the outer connecting pipe 2 0b protrudes to the outside, and the outer connecting pipe 20b does not hinder 'easy installation'. The assembly process of the double hose 2 becomes simple. In addition, the softness of the above The connecting pipes 20a inside and outside the pipe joint section 20

The other end of the "5" double hose 2 is attached and fixed to the connecting pipes 24a, 24b formed integrally with the handle portion 24 for operation at hand as described above. That is, the inner one-layer two-wire tube 2 a is screwed into the outer surface of the inner connecting tube 2 4 a to form a threaded rib 25 on the outer surface of the protruding end, and after the installation is fixed, the outer guide hose 2 b is installed on the outer connection. The tubes 24b are glued together. The mounting portion of the hose 2 is also covered with a cylindrical protective cover 26. In this case, as described above, when the one-layer first-line hose 2a which is difficult to install on the inner side is mounted on the inner connecting pipe 248, the hose mounting end thereof protrudes to the outer side than the hose mounting end of the outer connecting pipe 24b. The outer connecting pipe 24b is not obstructed and can be installed relatively easily. The assembly process of the double hose 2 becomes simple. The handle portion 24 is structured so that a partition wall portion 28 separating the suction flow path a and the exhaust flow path b from the suction port 27 of the connection pipe 3 is recessed inward only by a predetermined distance. A clamper 29 for fixing the connection pipe 3 is provided above the suction port 27. In addition, the wiring processing for connecting the coil wire 21 and the operation circuit board 24C of the handle portion 24 by "providing a layer of two-wire hose 2a on the inside" cannot be the same as the conventional one. However, in this embodiment, the connection pipe 24a 24b and the handle portion 24 are integrated, as shown in FIG. 4, the coil wire 21 can be connected to the operation circuit board 24c via a cable 21 &. As shown in FIG. 5, the connecting tubes 3 and 3 are formed integrally with the inner cylindrical portion 3 a and the upper portion of the inner cylindrical portion 3 a forming the suction flow path A having a substantially circular wearing surface and cover the inner cylindrical portion. 3 Except for the exhaust gas flow path B like a

In addition, the exhaust air passing through the exhaust flow path B is clean air from which dust is removed through the paper bag 7 or the dust filter 8 of the cleaner body 1, and it is not necessary to consider dust blocking as the inner cylindrical portion 3a. Forming & Plane Nearly 5 'In this embodiment, the exhaust gas flow path B is formed into a nearly crescent-shaped cross section, and the outer cylindrical portion 3b is formed as if the cross section is approximately circular. / Therefore, the weight of the upper integrated part can be reduced, and at the same time, the seedling can be reduced, and the internal and external sections become approximately circular in cross-section, which does not damage the strength and has excellent workability. Therefore, the connection tube 3 of the present embodiment has substantially the same shape and operability as the conventional one having no X-sucking compared to the conventional one having only X suction. Alternatively, the upper part of the connecting pipe 3 is installed with a cover 32 covering the cable A clamp 31 as usual.

When an IV vacuum cleaner configured as shown above is used, the suction of the mixed air < air passing through the connecting pipe 3 through the suction pipe A of the suction pipe A and the double private The μ sleeve aa is sucked into the cleaner body M. After the dust is sucked up by the suction air of the cleaner body, the fan 5 is removed through the cleaning paper bag 7 of the duster 8 and the motor 5a is cooled. The exhausted air is sucked to the electric blower. However, the exhaust port 11 from the exhaust fan A of the electric blower 5 is exhausted to the outside, and other self-suction. : It is divided from the cleaner body 1 through the exhaust flow path B of the double hose 2 and the exhaust flow path B of the main body 1 and the suction member 4 for the ground is returned, and the exhaust flow path using the ^ 3 is directed to The dust is circulated to the suction air path a of the connecting pipe 3 / the dust raised by the wind A is as described above. In the exhaust device of this embodiment, the suction air path A and the exhaust flow type dust can be realized. The substantial weight reduction or the double-hose measurement of the double hose 2 through which the surface temperature passes, can practically suppress the exhaust of the exhaust gas 2: = the lightness of the connecting pipe 3, that is, by exhausting one of the exhaust gas 2 adjacent to the atmosphere The advantages of the formula are concrete. Reduced and weakened, can be effectively restrained; except; room: exhaust wind, and also the dust rising from the seats again and again. The filter 8 or the like will exhaust the air to the outside, and therefore, the exhaust air itself using the paper bag 7 or fine dust plowing port η is cleaner. In addition, since the efficiency is improved, the exhaust gas is also reduced, and the exhaust filter 10 is cleaned. Milk cleansing is more effective. This is also consistent with the recent clear page 1218080. V. Description of the invention (9) The tube uses a built-in conductive tube 2a, but the built-in signal line of the unwired hose of the present invention has a shape-retaining, gold-shaped ring. Parts (conformal installation is clear, but regardless of the translucent effect of the same effect as above, the use of the built-in use does not use the built-in guide or the built-in guide through the double becomes easy and shape the hose, flexible hose Heavier, softer, lighter, and substantially lighter. The wires that make up the double-reconstructed conductive wires are more practical than the heavier hoses. The exhaust pipe is formed by the suction airflow path. The diameter of the hose can be quantified and exhausted. In addition, in the above-mentioned embodiment, 'the inner layer is soft and conformal, one layer of the second layer of the coil wire 21 is softly limited so', for example, it can also be called the second layer of four and the power line (power brush Use) while the hose itself is made of synthetic resin or conformal thread). Also, if the outer hose (lead tube flutter) is made semi-permeable or transparent, as long as it has transparency, the result can be obtained. The light effect of the invention can make the suction flow path lighter and lighter. 'Exhaust and return type electricity' also has a double structure by the hose. The inner hose uses a flexible path with a conformal device. The outside hose uses a small inside hose without a conformal device. The inside hose uses a larger ratio than the inside hose with a conformal device. The outside hose uses a suction channel and a 4-flow passage that does not have a conformal device. As shown above, according to the present invention, according to the present invention, the flexible hose of the flexible hose on the outside of the exhaust flow path is formed by 'and the flexible hose on the inside of the suction flow path is formed. The inner hose is a heavy hose, and it is used for the outer hose with a large diameter

Five 'Explanation of the invention (10) In addition,' Using the outer hose increases the surface area of the tube, which improves heat dissipation, and the temperature of the outer surface of the hose rises. Therefore, the borrowed temperature 'will not rise to the user due to the temperature rise. The concave and convex telescopic hose is soft because it can suppress the dual effects caused by the exhaust heat. The temperature of the outer surface of the dual hose is felt to a strange degree. The usability can be reduced by the softness of one of the dual structure hoses. The pipe insertion port is used to mount the vacuum cleaner on the outside of the rhyme. The side hose installation end will not interfere with the connection pipe to the side than the outer hose installation end. It can be installed more easily. The assembly process of the double hose becomes simple. The double soft & makes the inner hose opaque, so that the outer hose has the appearance of the effect of transparency-1 on the D-free, and the double hose is thick, but because of the thick The inner side of the guide tube J, which has transparency, becomes thinner. In addition, because the dust passes through the soft and opaque 'the dust-free clean air is passed through the outer side of the deer, the outer side of the hose is semi-transparent, and the ash attached to the inner side of the inner side is not visible'. It is not polluted, and the appearance of the double hose will not be affected by the inner tube-shaped portion and a part of the inner tube-shaped portion forming the suction flow path with a substantially circular cross-section through the connecting tube and integrally formed with the inner tube-shaped portion. It forms a cylindrical part outside the exhaust flow path, so there is no need to worry about dust blocking. The double hose that allows the suction flow path and exhaust flow path to pass through

In addition, the exhaust flow path of the tube is set as the carrying surface. It is approximately crescent-shaped, and the cylindrical portion on the outside of the tube is formed into a substantially circular cross-section. Compared with the conventional one that has only inhalation, it has no strange feeling and can obtain approximately the same shape and operability.
