[Examples]

Hereinafter, an example of an embodiment of the present invention will be described based on the attached drawings.

Fig. 2 is an overall appearance view of a vacuum cleaner according to an example of an embodiment of the present invention. 201 is a suction port for sucking air containing dust located on the surface to be cleaned, 202 is an extension pipe through which air passing through the suction port passes, 203 is a flexible hose through which air passing through the extension pipe passes, and 204 is a catching of the communication hose. Dust cleaner body. Then, the dust sucked from the suction port 201 is collected by the extension pipe 202 and the hose 203 to the cleaner body 204.

Fig. 3 is an external view of a cleaner body as an example of an embodiment of the present invention. The state in which the cleaner body is placed transversely in the state of use of the cleaner. The side of the hose connection port (suction port) 404 having the cleaner body is referred to as the front side, and the side having the opening and closing cover 303 is referred to as the upper side. Therefore, the downward direction is the direction of gravity action.

The cleaner body 204 is composed of an upper body 301 and a lower body 302, and has an electric blower (not shown) that can draw in air. The upper body 301 is provided with an opening and closing cover 303 that is rotatable on the upper side of the electric blower, and a portion (space) and an opening/closing cover 303 that are partitioned with respect to the electric blower of the lower body 302 constitute a dust collecting chamber 304. The dust collecting chamber 304 is disposed further forward than the electric blower on the front side of the cleaner body 204, and is disposed on the upstream side (the upstream side of the suction port of the electric blower) that flows along the air than the electric blower. In a state where the opening and closing cover 303 is closed, the opening and closing cover 303 is preferably in an airtight state in which the upper side of the dust collecting chamber 304 is airtight. The dust collecting chamber 304 is provided with a dust collecting bag 305 that is detachable in the vertical direction. The dust collecting bag is inserted by inserting the outer frame of the suction port of the dust collecting bag 305 downward into the sliding ribs (not shown) on both sides of the outlet end of the hose connecting port 404 provided in the dust collecting chamber 304. The 305 is supported in the dust collecting chamber 304. A filter frame member 306 having a filter for preventing dust from being attracted to the electric blower is provided between the electric blower and the dust bag 305, and in the dust collecting chamber. The filter and the filter frame member 306 form a filter portion. Although the mesh of the filter is thicker than the mesh of the dust collecting bag 305, it is possible to prevent dust remaining in the dust collecting chamber from being sucked into the electric blower. However, the filter frame member 306 does not need to be provided to the filter as long as the flow path can be secured.

Fig. 4 is a cross-sectional view showing the cleaner body of an example of the embodiment of the present invention.

A filter frame member 306 that holds the filter 403 is provided in the dust collecting chamber 304 between the electric blower 401 and the dust collecting bag 305. The filter 403 is detachably held by the user from the dust collecting bag 305 side. When the cleaner is in operation, the electric blower 401 generates an attractive force, and takes in air from the opening portion 402 that communicates with the dust collecting chamber 304. The dust bag 305 is inflated as shown in the drawing because of the dusty air flowing in from the hose connection port 404. The size of the dust bag 305 after expansion is made slightly larger than the size of the dust collecting chamber 304. When the dust collecting bag 305 is inflated and attached to the upper, lower, left and right walls of the dust collecting chamber, when the dust is large, the air is blocked. The flow. The dust bag 305 is not in an expanded state (initial mounting), and the surface (bottom surface) of the dust bag 305 facing the suction port of the dust bag 305 is separated from the filter frame member 306, and the dust bag 305 is inflated. The surface (bottom surface) of the dust collecting bag 305 that faces the suction port of the dust collecting bag 305 is in contact with the filter frame member 306. In the embodiment of the present invention, in order to prevent the dust bag 305 from adhering to the inside of the opening and closing cover 303, a rib-shaped flow path securing member 405 extending in the front-rear direction is provided inside the opening and closing cover 303, and the opening and closing cover 303 is opened and closed. A space (flow path) 406 is held between the dust collecting pockets 305 to prevent the suction force of the cleaner from being lowered. Further, by the filter frame member 306, even when the dust bag 305 is inflated, the space between the dust bag 305 and the opening 402 can be retained, and the attraction force can be prevented from being lowered.

Next, referring to Fig. 1 and Fig. 5, Fig. 6, Fig. 7, and Fig. 8, a filter frame member 306 which is a main portion of the present invention will be described. FIG. 1 shows a state in which the dust collecting bag 305 and the filter 403 are not provided in a state in which the opening and closing cover 303 is opened. The filter frame member 306 is slidable in the up-and-down direction (the direction taken out from the dust collecting chamber 304 of the dust bag 305), and FIG. 1 is in a state of being positioned at the upper end position of the slidable range. Usually, the filter frame member 306 is positioned at the lower end of the slidable range, but the user can easily remove the filter 403 before the electric blower (not shown). The opening portion 402 has a slightly rounded entrance end, and is located slightly in the center (the hose connection port 404) on the left side as viewed from the front of the cleaner body 204. The filter frame member 30 has a substantially rectangular shape and is formed to cover the opening portion 402, and is viewed from the front of the cleaner body 204, and is located at the center (the hose connection port 404) slightly to the left. The lower end of the filter frame member 306 may be in contact with the dust collecting chamber 304 when the filter frame member 306 is housed, or may not be in contact with each other. The filter frame member 306 is not set to the right side in order to secure the space (flow path). As a result, after the dust bag 305 is inflated, only the left side of the bottom surface of the dust bag 305 abuts against the filter frame member 306.

Fig. 5 shows a state in which the dust collecting bag 305 after the dust is sucked is extracted. As described above, when the user removes the dust bag 305 and pulls it upward, normally, since the filter frame member 306 does not slide in the vertical direction, the filter frame member 306 is caught in the dust bag 305 and is prevented from being drawn out. However, in the present invention, since the filter frame member 306 slides in the upward direction, the dust collecting bag 305 can be easily taken out together with the dust collecting bag 305, and the dust collecting bag 305 can be easily replaced. Further, in a state where the dust collecting bag 305 is withdrawn, the upper end of the filter frame member 306 abuts against a bone or a rib formed by the inner surface of the opening and closing cover 303.

FIG. 6 is a side view showing a state in which the dust collecting bag 305 is taken out, and it is understood that the filter frame member 306 is taken up together with the dust collecting bag 305.

Thereafter, as shown in FIG. 7, since the dust bag 305 can be easily removed, the replacement of the dust bag 305 is extremely simple. Moreover, the filter frame member 306 can also return to the lower end in the downward direction (toward the direction of gravity) due to its own weight immediately after the dust bag 305 is removed, and the filter frame member 306 can also stay at the upper end or the upper portion due to the static frictional force. .

Fig. 8 is a transverse cross-sectional view showing a state in which the dust collecting bag 305 is taken out. In particular, since the first locking of the start of the dust collecting bag 305 is difficult to remove, the approximately half of the dust collecting bag 305 is set by the sliding of the filter frame member 306 as shown in FIG. Since the dust chamber 304 is exposed, the dust bag 305 can be easily removed with one hand. The sliding range of the filter frame member 306 is about one-half of the length of the filter frame member 306 in the vertical direction, or about one-half of the length of the bottom surface of the expanded dust bag 305 in the vertical direction.

Fig. 9 shows a state in which the dust collecting bag is replaced (the filter 403 is not shown). When the filter frame member 306 is slid and positioned in the upper portion, the opening and closing cover 303 is rotated from the open state to the closed state, as shown in Fig. 10. The filter frame member 306 is pushed downward by the support bone or the rib of the inner surface of the opening and closing cover 303, and as a result, it is guided to the lower end position in conjunction with the rotation operation of the opening and closing cover 303. It is not necessary to lower the filter frame member 306 downward, so it is convenient to apply.

Further, as shown in FIG. 4, in the state in which the opening and closing cover 303 is closed, the upper portion of the filter frame member 306 is held by the opening and closing cover. Thereby, since the position of the filter 403 can be reliably set, it is possible to prevent dust from being attracted to the electric blower.

FIG. 11 is a state in which the opening and closing cover 303 is closed to the middle. The flow path securing member 405 is provided inside the opening and closing cover 303 to prevent the dust collecting bag 305 from being inflated and attached to the inner surface of the opening and closing cover 303, and the space 406 is secured, and the flow path to the air flow of the electric blower is secured. Further, a plurality of ribs 1101 extending in the vertical direction in a state in which the opening and closing cover 303 is closed are provided at the rear end of the opening and closing cover 303 inside the opening and closing cover 303. Thereby, even if the dust bag 305 is inflated, the dust bag 305 is not attached to the lower air path 1102 (space) of the opening and closing cover 303. Further, as shown in FIG. 9, at the upper end of the filter frame member 306, the upper air passage 901 that is open in the vertical direction is opened at a position opposed to the opening of the lower air passage 1102 formed by the plurality of ribs 1101. . Thereby, the air passing through the inside of the opening and closing cover 303 is smoothly guided to the electric blower.

Next, a detailed mounting state of the filter frame member 306 will be described with reference to Figs. 12 to 15 . Fig. 12 is an enlarged view of a portion P of Fig. 10; The filter frame member 306 is formed in a lattice shape as a whole, and reduces the resistance when the air flows as much as possible, and enhances the suction force. A filter 403 is disposed on the side of the dust bag 305 to prevent The dust enters the side of the electric blower. The filter frame member 306 is a convex portion 1201 that protrudes a part of the above-described lattice (a substantially intermediate portion in the vertical direction) on the side of the electric blower. The opening 402 of the lower body 302 also has a rib 1202 extending in a lattice shape (upward, lower, left, and right), and the convex portion 1201 is locked to the rib 1202 to prevent the filter frame member 306 from coming off the lower body 302.

When the vacuum cleaner is assembled, since the lower end of the convex portion has a right angle with respect to the upper end of the convex portion, the lower end of the convex portion has a curved portion 1203 (a tapered shape), and the filter frame member 306 is inserted into the lower body of the lower body shown in FIG. In the portion 1401, the curved portion 1203 of the convex portion passes over the rib 1202, and the filter frame member 306 can be simply attached to the lower body 302. Further, since the filter frame member 306 and the lower body 302 can constitute the above-described sliding mechanism only by the number of parts, it is possible to provide a vacuum cleaner which is excellent in productivity and cost-effective. The L-shaped portion 1401 is formed on the side wall surface of the cleaner of the dust collecting chamber 304, and is located on both sides of the opening 402, and extends in the vertical direction (the sliding direction of the filter frame member 306), and has a substantially L-shaped cross section in the vertical direction. . Between the L-shaped portion 1401 and the side wall surface of the cleaner of the dust collecting chamber 304, both sides of the filter frame member 306 in the left-right direction are slidably held in the vertical direction.

Fig. 13 is a view of the filter frame member 306 viewed from the side of the dust collecting chamber 304 (the filter 403 is not shown). Since the lattice portion 1301 of the filter frame member 306 completely coincides with the lattice-shaped rib 1202 provided in the opening portion 402 of the lower body 302 in the front-rear direction, the resistance at the time of air flow can be reduced as much as possible, and the suction force can be improved. Further, as can be seen from FIG. 14, it is preferable that the number of the lattice portions 1301 of the filter frame member 306 is smaller than the number of the lattice-shaped ribs 1202 provided in the opening portion 402. Thereby, the resistance during air flow can be further reduced, and the attraction can be further enhanced.

As described above, it is possible to provide a dust collecting bag that collects dust, which is easy to take out, has good suction efficiency, can enhance the attractive force, and can easily use a convenient vacuum cleaner even if dust accumulates in the dust collecting bag.

FIG. 15 shows an external view of the filter frame member 306. The filter frame member 306 has a slightly rectangular outer shape, a plurality of bones extending in the up-and-down direction, a plurality of bones extending in the left-right direction, and two of the plurality of bones extending in the up-and-down direction forming the bones. The convex portion 1201 and the rib 1501 for the filter are provided on the outer periphery. The upper and lower ends of the plurality of bones extending in the up-and-down direction and the left and right ends of the plurality of bones extending in the left-right direction are supported by the outer periphery, and the plurality of bones extending in the up-and-down direction and the plurality of bones extending in the left-right direction The bones are mutually supported by each other at their point of contact. The filter frame member 306 is composed of a single member (single structure). The filter frame member 306 is preferably made of plastic and is preferably formed by molding. It is preferable that the convex portion 1201 is formed on the lower side than the middle of the vertical direction of the filter frame member 306. A plurality of bones extending in the up-and-down direction and a plurality of bones extending in the left-right direction form a lattice. An upper air passage 901 that is open in the vertical direction is formed in an upper portion of the outer casing. The upper air passage 901 is formed on the front side more than a plurality of bones extending in the up-and-down direction and a plurality of bones extending in the left-right direction, and is preferably formed on the front side of the filter.

Further, in the above embodiment, the filter frame member 306 is provided as a mechanism for sliding in the vertical direction. However, the filter frame member 306 may be pivoted at the upper portion of the filter frame member 306, and the lower portion of the filter frame member 306 may be provided as a set. A mechanism for rotating the dust chamber 304 side. Further, in the above embodiment, the filter frame member 306 is formed on the side wall surface of the electric blower 401 of the dust collecting chamber 304, but may be formed on one or both of the side wall surfaces of the dust collecting chamber 304.
