Hereinafter, the embodiment of the present invention (configuration of one embodiment) will be described in detail with reference to the drawings when applied to the stick type vacuum cleaner. First, as shown in FIGS. 1 to 4, the stick-type vacuum cleaner 100 of this embodiment has a suction nozzle 110, a suction pipe 120 detachably connected to the suction nozzle 110 at one end, and the suction pipe 120. The vacuum cleaner main body 130, which is detachably connected to the other end of the vacuum cleaner body 130, and three components are basically provided.

Hereinafter, the configuration of the stick type vacuum cleaner 100 will be described in order of the suction nozzle 110, the suction pipe 120, and the vacuum cleaner main body 130.

First, the suction nozzle 110, which is the first component of the three components constituting the stick-type vacuum cleaner 100 of this embodiment, will be described in detail with reference to FIGS. 5 to 13. FIG. 5 shows a plan view of the nozzle body 1 which is a main constituent requirement of the suction nozzle 110, FIG. 6 is a side view of the nozzle body 1, and FIG. 7 is a side cross section shown by cutting along the line AA of FIG. The figures are shown respectively. Further, FIG. 8 shows a side sectional view shown by cutting along the line BB of FIG. 5, and FIG. 9 shows a side sectional view showing an enlarged main part of FIG. 7.

As shown in FIGS. 5 and 6, the nozzle body 1 made of plastic and made of a hollow body has an outer shell formed by an upper case 2 and a lower case 3, and a rubber cushioning material 4 is formed on the peripheral side portion. Is provided so that it will not be damaged even if it hits furniture etc. during cleaning.

Further, a substantially T-shaped shaft support portion 5 is provided swingably between the upper case 2 and the lower case 3 on the rear surface side of the nozzle body 1, and the shaft support portion 5 is provided at the rear portion of the shaft support portion 5 from the vacuum cleaner body. A cylindrical joint 6 having a substantially J-shape and a small diameter extending to the tip of the suction hose (not shown) is rotatably connected.

As shown in FIGS. 6 and 8, armor window-shaped suction portions 10 having a plurality of elongated holes 7 are provided on both sides of the upper surface of the nozzle body 1, and the suction portions 10 are disposed when the vacuum cleaner body is driven. Air is sucked into the nozzle body 1 from the portion 10.

10 shows a back view of the nozzle body 1, FIG. 11 shows an enlarged view of a main part of FIG. 10, and FIG. 12 shows a schematic enlarged perspective view of the main part. A suction port 12 is opened on the lower surface of the nozzle body 1 over substantially the entire length in the lateral direction, and louvers of ridges are formed on the lower surface of the nozzle body 1 on the front side with respect to the suction port 12 at predetermined intervals. 13 is integrally projected in parallel with the suction port 12 so as to be orthogonal to the suction port 12.

The front portion of the bottom surface 14 between the louvers 13 of the nozzle body 1 is curved as shown in FIG. 12, and each louver 13 protrudes from the bottom surface 14 by about 1 to 3 mm. Further, holes 15 and 16 for sucking air are drilled in the bottom surface 14 of the nozzle body 1, and a groove 17 is recessed in the bottom surface 14 in a substantially eight-shaped shape in communication with the hole 16 from one hole 16. ing.

Further, grooves 20 are recessed on both sides of the bottom surface 14 between the louvers 13 in the front-rear direction (direction orthogonal to the longitudinal direction of the suction port 12), and the grooves 17 communicate with the grooves 20. The front portion of the groove 20 is curved in the same manner as the shape of the bottom surface 14, and the front surface side of the groove 20 is in an open state.

A bifurcated rubber plate 21 is disposed on the bottom surface 14 near the suction port 12 between the louvers 13, and the central portion of the rubber plate 21, the end faces on both sides of the rubber plate 21, and the side surfaces of the louver 13 are arranged. Gap 22 and 23 are formed between them, respectively. The rubber plate 21 projects downward by about 1 to 2 mm from the lower surface of the louver 13.

Here, an air inflow path is formed by the bottom surface 14 between the louvers 13, the grooves 20 and 17 on both sides, the gaps 22 and 23 formed by the rubber plates 21, and the like. On the lower surface of the nozzle body 1 behind the suction port 12, louvers 30 having the same ridges as the louver 13 are integrally projected in parallel with the suction port 12 at predetermined intervals.

Here, as shown in FIGS. 10 and 11, the rear louvers 30 are laterally displaced with respect to the front louvers 13 so as not to be aligned with the front louvers 13 in the front-rear direction. It is set up. Each louver 30 extends to the vicinity of the rear edge of the lower case 3 of the nozzle body 1 and is integrally projected.

Each louver 30 protrudes from the bottom surface 32 of the lower case 3 by about 1 to 3 mm. Further, a long hole 33 in the lateral direction is formed in the bottom surface 32 of the lower case 3 of the nozzle body 1 for sucking air. A rubber plate 31 is provided on the bottom surface 32 at a position close to the suction port 12 between the louvers 30, and the rubber plate 31 projects downward by about 1 to 2 mm from the lower surface of the louver 30. Further, as shown in FIG. 10, traveling wheels 34 and 35 are rotatably provided at the four corners of the lower surface of the lower case 3 of the nozzle body 1.

The lower surfaces of the louvers 13 and 30 are separated from the floor surface by about 1 to 2 mm while the traveling wheels 34 and 35 of the nozzle body 1 are in contact with the floor surface, and the rubber plates 21 and 31 are separated from the floor surface. It comes into contact with the floor surface slightly to expel dust from flooring materials such as carpets and suck it in. Since the suction operation itself in the nozzle body 1 is not the gist of the present invention, the description thereof will be omitted.

Here, as shown in FIG. 10, a ridge 40 is integrally formed on the lower surface of the nozzle body 1 over substantially the entire length in the lateral direction in a shape orthogonal to each louver 30. The lower surface of the ridge 40 and the lower surface of each louver 30 are flush with each other. Then, as shown in FIG. 9, the lower surface of the nozzle body 1 forms an inclined surface 41 having a predetermined angle with the ridge 40 as a boundary. That is, an inclined surface 41 is formed on the lower surface of the nozzle body 1 in a direction away from the floor surface at a predetermined angle θ toward the rear of the ridge 40. When the shaft support portion 5 of the nozzle body 1 is pushed downward as a force point, the traveling wheel 35 at the rear sinks into the carpet with long hairs, and the ridge 40 acts as a fulcrum, and the front portion of the nozzle body 1 Can be raised above the floor.

As shown in FIG. 13, when the shaft support portion 5 is pushed downward as a force point, the dimension L at which the front edge portion of the suction port 12 of the nozzle body 1 rises from the floor surface is about 1 to 4 mm. The angle θ of the inclined surface 41 is set in the range of 1 to 6 °.

As a result, the surface of the floor material such as a long-haired rug is sucked by the nozzle body 1, and the hair feet are attracted to the air inflow path between the louvers 13 and 30, and the nozzle body 1 moves forward. When it becomes difficult to do so, by pushing the portion of the shaft support portion 5 downward, the traveling wheel 35 at the rear sinks into the floor material such as a long-haired rug, and the traveling wheel 35 sinks. The front part of the nozzle body 1 is lifted with the ridge 40 as a fulcrum, and the bristles are prevented from being crushed around the edges of the suction port 12 in the longitudinal direction, so that air flows into the air inflow path. The suction force can be restored to suck dust, and the nozzle body 1 can be smoothly moved forward.

Further, since the nozzle body 1 uses the inclined surface 41 as a slide, that is, the friction surface due to the effect of the louver 30 provided on the inclined surface 41 is reduced, the nozzle body 1 slides well on the floor surface such as a carpet and the nozzle body 1. The forward movement of the wheel 35 can be made smoother even if the traveling wheel 35 does not work.

In this way, in a flooring material with long hair and dense fibers, even when the nozzle body 1 is moved forward, the nozzle body 1 is not pressed against the flooring material, does not stick to it, and the suction force drops. To the extent that there is no such thing, an appropriate and appropriate gap with the floor material can be secured by easily raising the suction port 12 in a natural cleaning operation.

Further, instead of raising the front part of the nozzle body 1 with the edge portion of the rear part of the nozzle body 1 as a fulcrum as in the conventional case, the front part of the nozzle body 1 is set with the portion of the ridge 40 near the suction port 12 as a fulcrum. Since it is raised, the opening surface of the suction port 12 does not separate much from the floor material. Therefore, the suction force or suction force does not drop as in the past, and even in the case of flooring materials such as carpets with long hair, a constant suction force can be maintained and dust can be strongly sucked. can.

The ridge 40 has the same height as the louver 30, and cannot be operated with the ridge 40 as a fulcrum with a hard floor material such as flooring, but the floor material such as a carpet with long fluff can run at the rear. Since the wheels 35 are buried in the floor material, they can be easily operated with the ridge 40 as a fulcrum.

Further, the fulcrum with respect to the force point is a ridge 40, and the fulcrum 40 is provided behind the rubber plate 31, but the fulcrum may be provided at a position close to the rubber plate 31 side. Further, the ridge 40 may be at any height as long as it is between the above-surface position of the bottom surface 32 and substantially the same height as the louver 30.

Further, since the louvers 13 and 30 provided in the front and rear of the suction port 12 are not formed in a straight line in the front-rear direction as in the conventional case, and the front and rear louvers 13 and 30 are displaced in the lateral direction, the nozzle body 1 By simply moving the dust in the front-back direction, the dust can be sucked cleanly without leaving the dust in a streak like in the conventional case.

Next, the suction pipe 120, which is the second component of the three components constituting the stick type vacuum cleaner 100, will be described with reference to FIGS. 3 and 4 and FIG. The suction pipe 120 is configured to be detachably connected to the suction nozzle 110 at one end and to the vacuum cleaner main body 130 at the other end. Further, in particular, in this embodiment, since the suction nozzle 110 does not have a rotary brush that is rotationally driven by a motor as in recent years, it is not necessary to supply power to the suction nozzle 110 from the vacuum cleaner main body 130, and this result. The suction pipe 120 is composed of only a straight tubular pipe body. Therefore, in this embodiment, the suction pipe 120 can be constructed from a synthetic resin such as polycarbonate at low cost and in a lightweight state, and is excellent in terms of economy and operability. be.

As shown in FIG. 14, the other end of the suction pipe 120, that is, the outer peripheral surface of the end portion connected to the vacuum cleaner main body 130, is locked so as to be disconnected from the vacuum cleaner main body 130. The locking projection 122 for this purpose is arranged so as to project from the outer peripheral surface. The locking projection 122 moves in the axial direction by engaging with a locking groove (not shown) formed on the inner peripheral surface of the locking hook 132 arranged on the vacuum cleaner main body 130, which will be described later. Is prohibited, that is, it is configured to be locked so that they cannot be pulled out from each other. The locking hook 132 is urged by an elastic member (not shown) in a direction of engaging with each other, and is lifted against the urging force to lock the locking projection 122 and the locking hook 132. The engagement with the groove is released, and the suction pipe 120 is allowed to move in the axial direction, that is, it can be pulled out from the vacuum cleaner main body 130.

On the other hand, the vacuum cleaner main body 130, which is the third component among the three components constituting the stick type vacuum cleaner 100, will be described in detail with reference to FIGS. 15 to 25. The vacuum cleaner main body 130 includes a drive unit 134 (FIGS. 15 and 16) in which an electric motor, a fan that is rotationally driven by the electric motor to exert suction force, and a battery for driving the electric motor are housed (built-in). The filter unit 136, which is detachably connected to the drive unit 134 and collects the dust in the intake air that has been sucked by the suction nozzle 110 and has passed through the suction pipe 120, is housed inside. A dust collecting unit 138 (shown in FIGS. 17 and 18) that collects dust collected by the filter unit 136, and a connecting unit 140 that detachably connects the dust collecting unit 138 and the suction pipe 120 to each other are provided. It is roughly configured.

As shown in FIGS. 15 and 16, the drive unit 134 has a cylindrical shape in which an electric motor (not shown), a fan that is rotationally driven by the electric motor to exert attractive force, and a battery for driving the electric motor are housed. The drive unit main body 142, and the handle portion 144 extending upward from the outer peripheral surface of the drive unit main body 142 along the direction parallel to the axial direction, that is, in the direction away from the suction nozzle 110, and the handle portion. It is roughly configured with a power switch 146 disposed at the base end portion of 144, that is, the end portion attached to the drive unit main body 142. Although details are not shown, the end of the drive unit main body 142 on the dust collection unit 138 side is once fitted, and then latched by rotating along the circumferential direction to integrate the two. An engaging piece of a latch mechanism is provided.

Further, as shown in FIGS. 17 and 18, the dust collection unit 138 is closed to a cylindrical transparent collection container 148 with both end faces open and an open end surface of the collection container 148 on the drive unit 134 side. It is provided with a mounting portion 150 mounted so as to. On the outer peripheral surface of the mounting portion 150, a latch groove 150A corresponding to an engaging piece of the latch mechanism provided at the end of the driving portion 134 is formed in a state of extending by a predetermined range in the circumferential direction. As described above, since the collection container 148 is transparently formed, the inside of the collection container 148 is drawn in a transparent state as shown in the figure.

On the other hand, the filter unit 136 located in the collection container 148 includes a mesh filter 152 in which through holes for blocking the passage of coarse dust are formed over the entire peripheral surface as shown in FIG. 19, and as shown in FIG. 20. , The HEPA filter 154, which is coaxially arranged inside the mesh filter 152, allows coarse dust to pass through the mesh filter 152 from the outer periphery toward the center, and fine dust to be collected. Is configured to be integrally assembled as shown in FIG. 21. As shown in FIG. 17, the HEPA filter 154 is arranged in the recovery container 148 in a state of being biased toward the drive unit 134. That is, in a state where the filter unit 136 is inserted in the collection container 148, the internal space of the collection container 148 is vacant except for the filter unit 136.

Here, in the filter unit 136 shown in FIG. 19, the end surface on the left side of the drawing on the connecting portion 140 side is completely closed, while the end surface on the right side in the drawing on the drive unit 134 side is the central portion thereof. Is opened and is in a communication state with the drive unit 134. As a result, the intake air containing dust from the suction nozzle 110 brought from the connecting portion 140 is brought into the collection container portion 148 of the dust collecting portion 138, and the mesh is located on the outer periphery of the HEPA filter 154. The filter 152 is transmitted from the outer peripheral side toward the central portion, and first, coarse dust is collected by the mesh filter 152, and then the dust is further distributed toward the central portion, whereby the HEPA filter 154 is transmitted. Here, even fine dust is collected and flows out from the opening in the center toward the drive unit 134.

Further, as shown in FIG. 22, the above-mentioned connecting portion 140 includes a cylindrical main body portion 156 having the same diameter as the above-mentioned collection container 148, and the left end surface of the main body portion 156 in the drawing, that is, the suction nozzle 110 side. A bonding portion 158 is integrally attached to the end surface of the. The joining portion 158 has an opening (not shown) extending along the central axis and communicating with the suction pipe 120, and further, the above-mentioned locking is formed on the outer peripheral surface of the joining portion 158. A locking hook 132 that can be engaged with the protrusion 122 is attached in a state of being urged in a direction in contact with the outer peripheral surface by an urging member (not shown).

The end portion of the suction pipe 120 is fitted into this opening, and the locking projection 122 and the locking hook 134 engage with each other, so that the suction pipe 120 is attached to the mating portion 158 so as not to be pulled out. .. On the other hand, by moving the locking hook 134 in a direction away from the outer peripheral surface of the mating portion 158 against the urging member, the engagement with the locking projection 122 is released, and the suction pipe 120 is in the mating portion. It will be removed from the 158, that is, removed from the vacuum cleaner body 130.

Further, on the right end surface of the main body portion 156 in the drawing, a ring-shaped fitting portion 160 that fits into the open end surface of the suction nozzle 110 side of the dust collection unit 138 is integrally formed, and the fitting portion 160 is integrally formed. Also, an opening (not shown) extending along the central axis and communicating with the suction pipe 120 is formed.

Tissue paper 162 may be sandwiched between the connecting portion 140 and the dust collecting portion 138. As shown in FIG. 23, the tissue paper 162 captures the dust in the intake air sucked by the suction nozzle 110 by the above-mentioned filter unit 136 in a state of being sandwiched between the connecting portion 140 and the dust collecting portion 138. It functions as a pre-filter member for collecting dust in advance before collecting it. This is the most important feature of this invention, but since the dust is collected in advance by the tissue paper 162 before the dust is collected by the filter unit 136 in this way, the filter unit 136 collects the dust in advance. The amount of collected dust is reduced, the number of troublesome cleanings of the filter unit 136 is reduced, and the effect of being able to easily clean the filter unit 136 can be achieved.

Here, the connecting portion 140 is an abbreviation for tissue paper 162 sandwiched between the connecting portion 140 and the dust collecting portion 138 in a state where the connecting portion 140 does not interfere with the filter portion 136 when the connecting portion 140 is connected to the dust collecting portion 138. As shown in FIG. 23, a pushing member 164 for pushing and deflecting the central portion toward the filter portion 136 is provided. As shown in FIG. 22, the push-in member 164 is integrally formed coaxially with the main body portion 156, and has a base end portion having an opening (not shown) communicating with an opening (not shown) communicating with the suction pipe 120. 164A, a plurality of support stems 164B extending axially from the peripheral edge portion of the base end portion 164A toward the filter portion 135, and a plurality of support stems 164B supported by the tips of the plurality of support stems 164B and placed in a collection container 148. It is configured to include a tip pushing ring 164C that is brought to a position close to the filter portion 136 in the loaded state, and the intake air including dust brought from the suction pipe 120 is not obstructed in the collection container 148. It is structured so that it can be distributed.

As a result, the permeation area of the intake air sucked from the suction nozzle 110 is secured widely in the tissue paper 162, and it is possible to improve the dust collection efficiency by the tissue paper 162.

As for the attached state (that is, the sandwiched state) of the tissue paper 162 in this embodiment, first, as shown in FIG. 24, the central portion of the tissue paper 162 is first applied to the end surface of the pushing member 164 of the connecting portion 140, and then. As shown in FIG. 25, while maintaining the state in which the tissue paper 162 is applied, the connecting portion 140 is gradually pushed into the collection container 148 of the dust collecting portion 138, and as shown in FIG. 23 described above. , The connecting portion 140 is connected to the dust collecting portion 138. In this way, the connecting portion 140 and the dust collecting portion 138 are connected to each other, and the tissue paper 162 is sandwiched between the connecting portion 140 and the dust collecting portion 138. The tissue paper 162 in which dust is collected can be removed with the dust collecting portion 138 removed from the connecting portion 140.

In the stick type vacuum cleaner 100 configured as described above, the assembling operation of the stick type vacuum cleaner 100 will be described below.

As shown in FIGS. 3 and 4, the lower end of the suction pipe 120 is fitted into the suction nozzle 110 to assemble both, and the drive unit 134 and the dust collection unit 138 are assembled to each other. After that, as shown in FIG. 24, the tip of the pushing member 164 of the connecting portion 140 is covered with the central portion of the tissue paper 162, and the pushing member 164 covered with the tissue paper 162 is covered with the dust collecting portion as shown in FIG. 25. Push it into the collection container 148 of 138. Then, in a state where the connecting portion 164 is connected to the dust collecting portion 138, as shown in FIG. 23, the vacuum cleaner main body 130 is in a state where the tissue paper 162 is sandwiched between the connecting portion 164 and the dust collecting portion 138. It will be composed. Then, the upper end of the suction pipe 120 is fitted into the connecting portion 140 of the vacuum cleaner main body 130 configured in this way to assemble the two, whereby the tissue paper 162 is placed between the connecting portion 164 and the dust collecting portion 138. The sandwiched stick type vacuum cleaner 100 is assembled.

Next, a cleaning operation for cleaning the surface to be cleaned such as the floor by using the stick type vacuum cleaner 100 assembled in this way will be described.

First, by turning on the power switch 146, an electric motor (not shown) of the drive unit 134 is started, and a fan (not shown) is rotationally driven to generate suction force. By pressing the bottom surface 14 of the suction nozzle 110 against a surface to be cleaned such as the floor surface in such a state where the suction force is generated, dust on the surface to be cleaned is collected from a large number of suction ports 12 arranged in the width direction. Cleaning is performed by being sucked from the air inflow passages defined from the gaps 22 and 23 and sucked toward the vacuum cleaner main body 130.

Here, as described above, since the size of each of the gaps 22 and 23 is limited to be small, dust larger than this size will not be sucked. In other words, in the stick type vacuum cleaner 100, the gaps 22 and 23 of the suction nozzle 110 function as a kind of filter that prevents the suction of large dust. This function is of great importance in the context of using tissue paper 162 in this example. That is, in a vacuum cleaner equipped with a conventional power rotary brush and sucking in large dust from a large opening, the sucked large dust breaks the tissue paper 162.

In this case, as an effect of this embodiment, it is not possible to exert the effect of collecting dust in advance with tissue paper 162 prior to the filter unit 136 and reducing the number of troublesome cleaning operations of the filter unit 136. become. However, in this embodiment, since the suction nozzle 110 prevents the suction of large dust, the tissue paper 162 sandwiched between the connecting portion 140 and the dust collecting portion 138 may be torn by the large dust. It is effectively prevented, and the tissue paper 162 can sufficiently function as a pre-filter of the filter unit 136.

Since the dust is collected in advance by the tissue paper 162, the amount of dust finally collected by the filter unit 136 is reduced, which causes a troublesome filter unit including the HEPA filter 154. The number of cleaning operations (dust removal operations) of 136 can be effectively reduced, and the effect of extremely improving the workability of the user is exhibited.

On the other hand, the tissue paper 162 that functions as a pre-filter can use the tissue paper at home, and can be used at an extremely low cost without the need to prepare a special one separately. Further, when dust is collected on the tissue paper 162 and it becomes necessary to dispose of it, the dust is very easily collected by disconnecting the connecting portion 140 and the dust collecting portion 138 and separating them from each other. The collected tissue paper 162 can be removed from the stick-type vacuum cleaner 100. In this way, the tissue paper 162 in which the removed dust is collected can be thrown away as a "poi" in the trash can, and can be easily disposed of.

Needless to say, the present invention is not limited to the configurations and numerical values of the above-described embodiments, and can be variously modified without departing from the gist of the present invention.

For example, the tissue paper used in the above-described embodiment may be any thin sheet made of paper as long as it can collect dust, and it goes without saying that thin kitchen paper, non-woven fabric, or the like can be used. It goes without saying that the tissue paper referred to in the present invention is a concept including such a thin paper sheet.

Further, in the above-described embodiment, the case where the vacuum cleaner is applied to the stick type vacuum cleaner has been described, but the present invention is not limited to such an application, and the canister type vacuum cleaner widely used in ordinary households can be used. Needless to say, it can be applied.

As is clear from the above explanation, the vacuum cleaner according to the present invention uses a tissue paper as a pre-filter to collect dust on the floor or the like in advance, and collects the dust with this tissue paper. Since the dust that could not be collected is finally collected by the filter unit, the amount of dust collected by the filter unit is reduced, and as a result, the number of troublesome cleaning operations of the filter unit is suppressed. As a result, the work efficiency of the user during cleaning work is significantly improved, and its availability is extremely high.

In addition, the tissue paper that collects dust can be easily removed from the stick-type vacuum cleaner, and the tissue paper can be thrown into the trash can with the dust collected, without getting dirty like this. From this point of view as well, the work efficiency of the user during cleaning work is significantly improved, and its usability is extremely high.
