Description

  The present invention relates to a vacuum cleaner used in general households.

  In general, as a suction tool for sucking dust accumulated in a sash groove, a corner of a wall, or the like, a so-called gap nozzle whose suction destination is made into a substantially rectangular shape is used. However, in a sash groove or the like, there is a concave portion that cannot be inserted even at the tip of the gap nozzle, and dust cannot be absorbed at such a location. In order to solve such problems, there is one that is provided with an air outlet that is attached to the suction port and injects blown air from a blower or the like. This is because the air blown from the air outlet blows out dust on the surface to be cleaned. It aims at the effect of making it float once and attracting | sucking (for example, refer patent document 1).

JP 2001-321305 A

  However, in the configuration of the conventional example using the blowout air described above, the blowout port is provided at one place, and the suction port and the blowout port are arranged substantially in parallel, and the blowout air emitted from the blowout port is cleaned. When it collides with the surface, it will flow laterally along the surface to be cleaned, so the dust on the surface to be cleaned often scatters sideways instead of flying up. It will be less.

  For this reason, as described in Patent Document 1, a bristle brush or the like configured to surround the air outlet is shown around the suction port. In this case, even if the air blown from the air outlet collides with the surface to be cleaned and flows laterally, it hits the bristle brush and flows up to the suction port as it is, but eventually the bristle brush enters. The effect can be exhibited only in the concave portion that can be formed.

  SUMMARY OF THE INVENTION The present invention solves the above-described conventional problems, and provides a vacuum cleaner suction tool that can absorb dust even in places where the tip of a suction tool such as a gap nozzle does not enter and cannot suck dust. provide.

  In order to achieve the above object, the vacuum cleaner suction tool of the present invention has a suction port that opens at the tip of the suction tool, and a plurality of injection nozzles that blow the blowout air adjacent to the periphery of the suction port. The injection nozzle is connected to a blower generating blown air or a pump generating compressed air via a piping unit, and the injection nozzle is focused near the front center of the suction port. The injection nozzles are arranged and configured at positions that are equally divided around the suction port.

  By such an invention, the tip of a suction tool such as a gap nozzle or the like, such as a sash groove, does not enter, and even if blown air is blown to the surface to be cleaned, In this way, the air blown against the surface to be cleaned does not scatter in the direction around the surface, but the air blows back and concentrates toward the suction port, so that the dust can be efficiently raised and absorbed. become.

  The suction tool for the vacuum cleaner of the present invention is efficient in a state where the suction tool is lifted from the surface to be cleaned even in a place where the tip of the suction tool such as a gap nozzle does not enter due to a sash groove or the like. Can absorb dust.

  1st invention arrange | positions the suction port opened at the front-end | tip of a suction tool, and the injection nozzle which blows off blowing air adjacent to the circumference | surroundings of the said suction port, The said injection nozzle blower which generate | occur | produces a blowing wind, Alternatively, the injection nozzle is connected to a pump that generates compressed air via a piping portion, and the injection nozzle is formed to be inclined with respect to each other so that the injection nozzle is focused near the front center of the suction port. The nozzle is arranged and arranged in a position where the periphery of the suction port is equally divided, so that the tip of a suction tool such as a gap nozzle does not enter and can not suck dust, such as a sash groove. Even if blowing air is blown onto the surface to be cleaned, the air blowing on the surface to be cleaned concentrates and returns toward the suction port without splashing around the surface to be cleaned as in the past. And effective Well rise up the dust will be able to dirt pick-up.

  According to a second aspect of the present invention, there are four or more injection nozzles, so that the air blown from the pair of injection nozzles collides and flows on the surface to be cleaned in a substantially vertical direction. The injection nozzle disposed at a position where the pair is inverted by 90 degrees can stop the flow in the peripheral direction, and the blowing air from the injection nozzle can be efficiently swirled to the suction port side.

  According to a third aspect of the present invention, an irradiation light is provided in parallel to the injection nozzle so as to illuminate the injection destination from the injection nozzle, and each irradiation light of the irradiation light is focused on the surface to be cleaned and becomes circular. The point where the dust can be sucked can be visualized by notifying that the position is the optimum position for dust suction.

  According to a fourth aspect of the present invention, a distance sensor for measuring a distance in a direction perpendicular to the surface to be cleaned is provided at the tip of each injection nozzle, and when each of the distance sensors is aligned within a certain value range, the blowing air is blown from the injection nozzle. By being configured to blow out, the dust on the surface to be cleaned is scattered around in a state deviating from the optimum injection angle, so that it can be prevented and the usability can be improved.

  According to the fifth aspect of the invention, the flow of the blown air blown from the injection nozzle is intermittently blown, so that the flow of the blown air to the surroundings can be further suppressed, and dust can be further prevented from being scattered.

6th invention was equipped with the vacuum cleaner main body which equipped with the electric blower which generate | occur | produces suction power, and the suction tool of any one of said 1st to 5th invention connected to the suction passage side of the said vacuum cleaner main body. By providing the vacuum cleaner, the normal cleaning range can be further expanded with a single vacuum cleaner.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. Note that the present invention is not limited to the present embodiment.

(Embodiment 1)
The vacuum cleaner suction tool according to the embodiment of the present invention will be described with reference to FIGS. As shown in FIGS. 1 to 3, a suction port 2 is provided at the center of the tip of the suction tool 1, and the injection nozzles 4 that blow out the blown air 3 are equally arranged in four directions around the suction port 2. The rear end of the suction tool 1 is provided with a joint portion 5 for mating with the tip pipe (not shown) of the hose and the tip of the extension pipe (not shown). The suction end 6 communicates with the joint 5 at the rear end.

  An injection nozzle 4 provided around the tip of the suction tool 1 communicates with a blower 7 disposed in the outer portion of the suction tool 1 through a pipe 8, and air taken from the air inlet 9 by the blower 7 is piped. 8 is configured to blow out from the tip of the injection nozzle 4. Here, a pump for generating compressed air may be used as a generation source of the blowing air 3.

  The outlet 10 of each injection nozzle 4 is inclined toward the front center of the inlet 2 in the range of about 30 to 50 degrees with respect to the extending direction of the inlet 2. And in order to raise the radiant power of the blowing wind 3, the aperture diameter of the blower outlet 10 is set in the range of (PHI) 1.5-3mm. Further, the shape of the outlet is tapered, so that the emission angle of the blown air current does not suddenly expand as indicated by the two-dot chain line in FIG.

  Next, the effect | action by the blowing wind of the injection nozzle 4 is demonstrated. The blowout air 3 blown out from the injection nozzles 4 and 4 ′ at one symmetrical position sets the blowout angle of the blowout opening 10 so as to collide with each other at a position about 20 to 40 mm away from the front of the suction opening 2. When the surface to be cleaned is aligned with the collision position between the blowing airs 3a and 3a ', the blowing airs 3a and 3a' are reflected on the surface to be cleaned and the air flow that changes the direction toward the suction port 2 and the blowing direction. An air flow is generated in a direction perpendicular to the surface to be cleaned.

  Here, the blowing air 3b, 3b 'is simultaneously ejected from the other pair of ejection nozzles arranged at positions inverted by 90 ° with respect to the pair of ejection nozzles described above. The blowing airs 3a, 3a ', 3b, 3b' that are emitted from the nozzle 4 are reflected in the surface to be cleaned because they are arranged in a direction that reflects and cancels out the airflows that are about to flow along the surface to be cleaned. All airflows are airflows returning to the inlet (FIG. 4).

  Due to the flow of the air flow, the suction port 2 of the suction tool 1 is not grounded to the surface to be cleaned, and the blown air 3 that is injected symmetrically with the suction port 2 separated from the surface to be cleaned sucks dust on the surface to be cleaned. It blows up toward the mouth 2 and can inhale it without blowing away the garbage around.

  Further, if the blowing air 3 from the injection nozzle 4 is blown intermittently, the frequency of generation of the air flow that flows in the peripheral direction and scatters dust is further reduced by the reflection of the blowing air 3 on the surface to be cleaned. It will be.

  Here, if the blowout from the injection nozzle 4 is switched by an ON / OFF switch arranged at the hand-operated portion, erroneous operation of the blowout can be suppressed.

  Moreover, in embodiment of this invention, although the air blower 7 which is a generation source of the blowing air 3 from the injection nozzle 4 is set as the structure provided in the outer periphery of the suction tool 1, the air blower 7 is made into the front end pipe part of a hose, or extension. It is good also as a structure which is comprised in a pipe | tube and connected with the injection nozzle provided in the suction tool via the connection pipe | tube, and injects a blowing wind. In this case, it is possible to perform “wiping and cleaning” in which only the blowing air is injected from the hose tip pipe portion (or extension tube tip) without attaching the suction tool 1.

(Embodiment 2)
The figure shows the configuration of the injection nozzle in the second embodiment. In addition, about the structure which overlaps with Embodiment 1 mentioned above, the same code | symbol is described and description is abbreviate | omitted.

  As shown in FIG. 5, an irradiation light 11 using a condensing LED as a light source is provided in each injection nozzle 4 so as to illuminate light focused substantially in parallel with the blowing air 3 from the injection nozzle 4, and the power supply It is set as the structure supplied from the cleaner main body via the connector junction part 12 of the tool 1 and the hose front-end | tip part (or extension pipe front-end | tip part).

  Each pair of light interferes similarly in the vicinity where the pair of blowing winds 3 collide. When this interfering irradiation light is applied to the surface to be cleaned, when the suction tool is tilted (FIG. 6), the interference light is elliptical as shown in the figure, and its outline is somewhat blurred. Become. And in the state where the suction tool is perpendicular to the surface to be cleaned, the light that illuminates the surface to be cleaned becomes round, and as shown in FIG. When the distance between the suction tool 1 and the surface to be cleaned coincides, the light that illuminates the surface to be cleaned has a clear outline.

  Further, when the suction tool 1 is moved away from this state (FIG. 7), the light that illuminates the surface to be cleaned becomes blurred in its outline, and the merged blowing air is in a direction substantially perpendicular to the surface to be cleaned. Since the airflow is generated, the blowing air 3 reflected from the surface to be cleaned flows in the peripheral direction along the surface to be cleaned, and thus dust is scattered. That is, the state in which the light that illuminates the surface to be cleaned is illuminated in a round shape with a clear outline is the optimum state in which dust is reliably blown out by the blowing air 3 from the injection nozzle 4, and if the distance deviated from this state, If it is at an angle, the blown air 3 from the injection nozzle 4 will flow in a direction in which dust is scattered.

  Therefore, if the blowing air 3 is emitted after confirming the sign of this light, the dust can be reliably blown up and sucked from the suction port 2 without being scattered.

(Embodiment 3)
The figure shows the configuration of the injection nozzle in the third embodiment. In addition, about the structure which overlaps with Embodiment 1 mentioned above, the same code | symbol is described and description is abbreviate | omitted.

  As shown in FIG. 8, a distance sensor 13 that senses a spatial distance by infrared rays is disposed at the tip of each injection nozzle 4.

  When the response values of the distances between the injection nozzles 4 and the surface to be cleaned are all within the preset setting range value, the blowing air 3 continues to be emitted from the injection nozzles 4 and one of the response values is set. When it is out of the range, it is set so that the blowing air 3 is not injected from the injection nozzle 4.

  As a result, since the distance sensor 13 reliably senses the optimum position of the blowing air 3, the position of the blowing air is not brought to the position where dust is scattered due to an error in human operation. The operability of the tool can be further improved.

  As described above, the suction tool for a vacuum cleaner according to the present invention has a plurality of symmetrically arranged injection nozzles, and injects the blowing air emitted from the injection nozzles toward the front of the suction port. As a result, the blowing air reflected on the surface to be cleaned is a flow that folds back toward the suction port while suppressing the reflection in the circumferential direction of the surface to be cleaned. Even in places where it is difficult to suck up because the tip does not enter, the dust can be reliably blown up and sucked in without releasing the dust around the suction port. It can be used not only for vacuum cleaners but also for various types of vacuum cleaners such as commercial vacuum cleaners.
