Description

  The present invention relates to an air suction / injection device used in a vacuum cleaner and a vacuum cleaner provided with the air suction / injection device, and in particular, it is possible to inject air using suction of air by a vacuum cleaner, The present invention relates to an air suction / injection device capable of switching between suction and injection, and a vacuum cleaner including the same.

  A general vacuum cleaner has a function of sucking dust together with air by sucking air (hereinafter referred to as “vacuum function”). A configuration having a function of blowing (hereinafter referred to as “blower function”) has also been proposed. If the vacuum cleaner has a blower function, it is difficult to see for the user (the back side of the installed furniture, the top surface, etc.) or a high position as seen from the user (the top surface of the furniture, the umbrella of lighting, It becomes possible to clean the dust on the ceiling.

  As a specific blower function, a technique using exhaust gas has been conventionally known. This exhaust is a flow of air that has passed through the dust collection chamber of the vacuum cleaner, but in the actual blower function, it is a clean air flow. However, the user has an unsanitary image in that exhaust is used. In addition, if the blower function uses a suction hose or extension pipe, etc., it is suspected that a small amount of dust adhering to the inside will be ejected, so the user still has an unsanitary image. End up. Therefore, recently, various blower functions that do not use exhaust gas have been proposed.

  For example, Patent Literature 1 discloses an air suction / injection device that includes a suction fan that operates by suction force, an injection fan that generates injection force, and power transmission means that transmits power of the suction fan to the injection fan. It is disclosed. According to this configuration, the injection fan can be rotated by the suction force of the vacuum cleaner simply by connecting the air suction / injection device to the suction hose. Therefore, a blower function that does not use exhaust can be additionally used regardless of the type of vacuum cleaner.

  Further, Patent Document 2 discloses a suction tool for a vacuum cleaner having a configuration including a pressure generation unit that feeds air into a jet nozzle provided in a suction port. This suction tool injects compressed air generated by a pressure generating unit such as an air pump from an ejection nozzle, and sucks dust that has adhered to the surface to be cleaned or accumulated in the back of the concavo-convex part. Therefore, a blower function that does not use exhaust gas can be realized, and dust blown off by the blower function can be quickly sucked, so that efficient dust collection is possible.

However, in the form of using the vacuum cleaner exhaust as in the conventional example for the blower, even if it is actually clean exhaust, it may have an unsanitary image in terms of using exhaust that sucks dust, In the case of using a hose or extension pipe that is used for sucking dust as in the conventional example, there is a risk of a small amount of dust adhering to the path being ejected, so there are concerns about hygiene and there are opportunities for use. In recent years, there are fewer vacuum cleaners with a blower function in this form.

  In addition, dust blows away simply by blowing, and in the recent highly airtight housing situation, it simply becomes a function that is difficult to use by simply diffusing the dust.

  The present invention is intended to solve the conventional problems as described above, and is not affected by the form of a suction generator such as a vacuum cleaner, and has a sanitary blower function, and its ejection is intermittent. An object of the present invention is to provide an air jet device and a vacuum cleaner using the air jet device that are very easy to use by allowing the dust blown out at a high pressure to be immediately recovered.

  In order to solve the above-described problems, an air suction / injection device of the present invention is connected to the tip of a suction hose included in a vacuum cleaner, and a suction chamber acts on the suction hose, and is provided in the suction chamber and rotated by the suction force.

  According to this configuration, since the injection port is normally closed, air can be stored by the injection fan while the injection port is closed, and the air can be injected at once by opening the injection valve. By taking in the air to be ejected by the suction force acting on it and increasing the pressure of the air taken in by the injection valve and ejecting it at once, it is hygienic regardless of the form of the suction generator such as a vacuum cleaner Since it has a blower function and the jets are intermittently jetted at a high pressure and the dust blown off at that time can be recovered immediately, an air suction jet device that is very easy to use can be provided.

  The air suction / injection device may be provided with operation means for opening the injection valve so that a user can operate the operation means. The user can open the injection valve at an arbitrary timing, and since the user can arbitrarily use the blower function according to the cleaning situation, it is possible to clean the apparatus conveniently and efficiently.

A drive shaft that is rotated by the pressure in the injection chamber, and the injection valve is opened in conjunction with the rotation of the drive shaft so that intermittent injection can be performed, and air can be intermittently injected at a predetermined timing. An easy-to-use vacuum cleaner that does not bother the user can be provided.

  In the air suction / injection apparatus, a power generation means for generating electric power by rotation of a suction fan and an electromagnetic valve for driving the injection valve may be provided, and the electromagnetic valve may be operated intermittently by the electric power generated by the power generation means. The electromagnetic valve is intermittently operated by the electric power generated by the power generation means to perform injection. Since the injection valve can be opened and closed by electric power, a high-precision blower function with higher accuracy can be provided.

  The air suction / injection device may include display means for displaying the pressure in the injection chamber. Since the user can visually determine the amount of air to be injected, by enabling the setting, it is possible to provide an air injection device that is easier to use.

The present invention also includes a vacuum cleaner comprising the air suction / injection device and a suction hose provided with the air suction / injection device. In the vacuum cleaner which concerns on this invention, although the said air suction injection apparatus should just be connected to the said suction hose, Preferably, it is connected with respect to the said suction hose so that attachment or detachment is possible.

  According to the air injection device and the vacuum cleaner using the air injection device of the present invention, the air to be ejected by the suction force acting on the suction chamber is taken in, and the pressure of the air taken in by the injection valve is increased and ejected at once. Therefore, it has a hygienic blower function regardless of the form of the suction generator such as an electric vacuum cleaner, and the spray is ejected intermittently at high pressure, and the dust blown off at that time can be immediately recovered. Therefore, it is possible to provide an air jet device that is very easy to use and a vacuum cleaner using the air jet device.

  Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings. In the following description, the same or corresponding elements are denoted by the same reference symbols throughout the drawings, and redundant description thereof is omitted.

(Embodiment 1)
First, an example of a vacuum cleaner provided with the air suction / injection device according to Embodiment 1 of the present invention will be specifically described with reference to FIG. As shown in FIG. 1, the air suction / injection apparatus 1 according to the present embodiment is provided in a typical canister-type vacuum cleaner 50. That is, the canister-type vacuum cleaner 50 (hereinafter simply referred to as the “vacuum cleaner 50”) includes a cleaner main body 51, a suction hose 53, a hand operating portion 54, a suction extension pipe 55, a suction port body 56, and an air suction jet. A device 1 is provided.

  The vacuum cleaner body 51 includes an electric blower 57, a dust collection chamber 58, a wheel 59, and a power cord 60, and one end of the suction hose 53 is detachably connected via a connection pipe 52. A hand operating part 54 is provided at the other end of the suction hose 53, and one end of the suction extension pipe 55 is detachably connected to the tip of the hand operating part 54. Further, a suction port body 56 is detachably attached to the other end of the suction extension pipe 55. Further, the air suction / injection device 1 is detachably attached to the lower side of the hand operation unit 54, and the air suction / injection device 1 can be attached to the tip of the hand operation unit 54 instead of the suction extension pipe 55. ing.

  The vacuum cleaner main body 51 is provided with an electric blower 57 and a dust collecting chamber 58 inside. A suction force is generated by the operation of the electric blower 57, and the suction port body 56 is connected via the suction hose 53 and the suction extension pipe 55. A suction force is generated at a suction port (not shown). A power cord 60 is housed inside the vacuum cleaner body 51 so as to be able to be pulled out. Moreover, the cleaner main body 51 is configured to be movable on the floor surface by a pair of wheels 59 provided on both sides.

When using the vacuum cleaner 50, first, the user pulls out the power cord 60 from the cleaner body 51, inserts the power plug at the tip into the power inlet, and operates the hand operation unit 54 to use the vacuum cleaner 50. Turn on the main body 51. As a result, suction force is generated at the suction port of the suction port body 56 by the operation of the electric blower 57, so that dust on the floor is sucked and collected through the suction extension pipe 55, the suction hose 53, and the connection pipe 52. Collected in chamber 58.

  The user changes the area of the floor surface to be cleaned by gripping the hand operation unit 54 and moving the position of the suction port body 56 on the floor surface. Further, when changing the place of cleaning, the vacuum cleaner main body 51 moves on the floor surface by the rotation of the wheel 59 by pulling the suction hose 53. Note that the cleaner body 51 is provided with a handle (not shown), so that the cleaner body 51 can be lifted and moved.

  Also, (1) cleaning at a position that is difficult for the user to see or at a high position, (2) cleaning dust that has adhered to the surface to be cleaned or accumulated in the back and forth of the uneven portion, and (3) damage if the suction port is brought close to the surface. In addition, when it is desired to clean an object that may cause undesired movement, erroneous operation, or erroneous suction, the blower function can be suitably used in addition to the normal vacuum cleaning (vacuum function cleaning). . Therefore, the suction extension pipe 55 or the suction port body 56 is removed, and the air suction / injection apparatus 1 is attached instead for cleaning.

  The specific configuration of the vacuum cleaner 50 shown in FIG. 1, that is, the vacuum cleaner main body 51, the suction hose 53, the hand operation unit 54, the suction extension pipe 55, the suction port body 56, and the like are not particularly limited. Various configurations known in the field can be suitably used.

  Next, the air suction / injection device 1 will be described with reference to FIGS. 2 is a partial cross-sectional view showing the internal configuration of the air suction / injection apparatus 1 according to the first embodiment of the present invention. FIG. 3 is a cross-sectional view taken along line AA in FIG. 2, and FIG. 4 is a cross-sectional view taken along line BB in FIG. FIG.

  The air suction / injection apparatus 1 is divided into a suction flow path in which an air flow is generated by the suction force of the vacuum cleaner 50 and the like, and a jet flow path in which air is sucked and ejected from the outside. The suction flow path has a suction port 3 having a suction port 2 for sucking outside air, which is rotatable 90 degrees in the vertical direction, communicates with a suction chamber 6 equipped with a suction fan 5 inside, and the suction chamber 6 has a discharge port 4. The suction force of the vacuum cleaner 50 or the like is applied through the through hole.

  In the ejection flow path, a second suction port 9 for sucking outside air and a spray chamber 11 provided with a spray fan 10 inside communicate with a spray tube 8 having a spray port 7 and rotatable 90 degrees in the vertical direction. . The suction chamber 6 and the ejection chamber 11 are connected to each other by a connecting portion 12, and the suction fan 5 and the ejection fan 10 are connected by a rotating shaft 14 that is a power transmission means.

  The suction fan 5 and the ejection fan 10 are formed of a sirocco type fan as shown in FIGS. 3 and 4, and the discharge port 4 is formed at the center of rotation of the suction fan 5 on the suction chamber 6 and the second suction port 9. Is arranged in the center of rotation of the injection fan 10 on the injection chamber 11 so as to open.

  In addition, the injection port 7 is provided with an injection valve 15 for opening and closing, and the injection valve 15 is made of an elastic body or the like, and acts to close the injection port 7 in a normal state. An injection valve closing means 17 is provided. The injection valve 15 is connected to an injection valve opening means 16 constituted by a valve rotation shaft for opening the injection valve 15 and a drive wire. The user operates the injection valve opening means 16 with the opening / closing operation means 18. The injection valve 15 can be opened and closed.

The operation in the above configuration will be described. When the discharge port 4 of the suction chamber 6 is connected to a suction hose or the like of a vacuum cleaner, air is sucked from the discharge port 4 so that air flows into the suction chamber 6 from the suction port 2 and rotates the suction fan 5. . The rotational force of the suction fan 5 rotates the spray fan 10 via the rotation shaft 14, and the spray fan 10 rotates, whereby air is sucked into the spray chamber 11 from the second suction port 9 and the spray port 7. Air is jetted toward it. Since the injection port 7 is normally closed by the injection valve 15, air is compressed in the injection pipe 8.

  At this time, when the user operates the opening / closing operation means 18, the injection valve 15 is opened by the drive wire constituting the injection valve opening means 16 and the rotating shaft, and the air compressed and stored in the injection pipe 8 is stored. It is ejected from the ejection port 7 at a stretch. Thereafter, when the opening / closing operation means 18 is returned, the injection valve 15 returns to its original position by the elastic body constituting the injection valve closing means 17 and closes the injection opening 7.

  The jetted air blows away dust and dirt accumulated on the object, and the blown-off dust and dust fly up on the spot and are sucked together with the surrounding air from the suction port 2 near the injection port 7. Collected. It becomes easy to inhale dust from the suction port 2 by closing the injection port 7.

  From these actions, any device that generates a suction action can be converted into an injection action as long as the suction pipe 3 and the suction generator are connected, and blown off at an arbitrary timing. In addition to collecting dust and dust, it is possible to provide a highly convenient and hygienic spray device.

  In addition, when using the blower function, it is possible to adjust the distance from the remote location to the position where the user blows away the target dust or dust. After spraying, it will be cleaned close to the target so that it will not diffuse, but by opening and closing the spray port 7, it is possible to concentrate on suction, so that the efficiency of cleaning can be increased.

(Embodiment 2)
FIG. 5 is a partial cross-sectional view showing the internal configuration of the air suction / injection device 1 according to the second embodiment of the present invention. A pressure driving means 20 including a rotatable disk, a weight, a pressure supply path, a driving wire, and the like is provided in the injection pipe 8. The operation setting of the pressure driving means 20 can be adjusted by a drive adjusting means (not shown). The display means 21 is made of an elastic body or the like, and its position is displaced by the pressure in the injection tube 8.

  The operation in the above configuration will be described. The pressure in the injection pipe 8 is increased by the air sucked from the injection fan 10, and the weight provided in the disk of the pressure driving means 20 is gradually lifted by this pressure, and slips down on the opposite side by exceeding the apex. At that time, the driving wire connected to the weight is pulled, the injection valve 15 is opened, and the air in the injection pipe 8 is ejected at a stroke. After the weight slides down the disk, the drive wire is loosened while the weight is lifted up to the apex, and the injection valve 15 is closed by the injection valve closing means 17 during that time. By this function, it is possible to intermittently inject air at a predetermined timing, and it is possible to provide a user-friendly intake injection device that does not bother the user. In addition, if the injection valve 15 can be opened and closed intermittently using pressure, it is needless to say that the means need not be limited, and for example, an elastic body, a piston, a rod structure, and the like may be combined.

  In addition, by providing a window in the injection chamber 11 and providing the display means 21 in which the mark is displaced to the user according to the internal pressure, it is possible to visually confirm how much pressure is set for injection and driving. If the required amount for moving the weight can be changed by the set pressure of the adjusting means (not shown), the user can also adjust the injection pressure and timing.

In addition, if valve opening means (not shown) that holds the injection valve in an open state is provided, for example, by a slide lever and a saddle structure, it is not intermittent injection according to the required situation, and even if the pressure is low, the injection is always performed. You can also improve usability. Needless to say, there is a means for adjusting the opening area of the injection port 7 in order to prevent the pressure from decreasing.

(Embodiment 3)
FIG. 6 is a partial cross-sectional view showing the internal configuration of the air suction / injection device 1 according to the third embodiment of the present invention. A generator 25 composed of a coil or the like that generates electricity by rotation of the rotating shaft 14 and a power generation circuit 26 that smoothes the electromotive force and uses it as a predetermined DC voltage source are disposed in the vicinity of the connecting portion 12, and this power generation Using the power of the means, the solenoid valve 30 for opening and closing the injection valve 15, the pressure detection means 28 for detecting the pressure in the injection pipe 8, and the judgment of the operation of the solenoid valve 30 from the result of the pressure detection means 28 Means 29 are provided. Furthermore, a setting unit 31 is provided that can arbitrarily change the setting value determined by the determination unit 29.

  The operation in the above configuration will be described. As described in the above embodiment, the convenience of use can be improved by adjusting the injection pressure of the air and controlling the injection timing by opening and closing the injection valve 15. Therefore, the determination unit 29 determines the pressure of the pressure detection unit 28 that generates electric power by the generator 25 from the rotation of the rotating shaft 14 to constitute the power supply circuit 26 and detects the pressure in the injection chamber using the electric power. By opening and closing the injection valve with the electromagnetic valve 30, it is possible to configure an injection mechanism having a simple structure with high accuracy.

  At this time, in the initial state where no electric power is generated, the injection valve 15 is closed by using magnetic force or elastic force. When suction force is generated, electric power is also generated, and the determination means 29 determines the set value of the pressure detection means 28 constantly or intermittently, but as the air is sent from the injection fan 10, the pressure of the air in the injection pipe 8 is increased. When the pressure rises and the pressure reaches a predetermined pressure value set by the setting means 31, the electromagnetic valve 30 is driven to open the injection valve 15, and air is injected.

  When the pressure is lowered by the injection, the solenoid valve 30 is operated again and the injection valve 15 is closed. At this time, the configuration for closing the injection valve 15 may use an injection valve closing means formed of an elastic body or a magnet without using electric power. The pressure at which the solenoid valve 30 operates can be visually confirmed by the display means 21. However, as a configuration interlocked with the setting means 31, for example, an internal pressure is indicated by an electric body such as an elastic body or an LED. If the solenoid valve 30 is operated at the timing at which the positions coincide, it becomes easier for the user to understand.

  The setting of the setting means 31 is not limited to the pressure, and the intermittent period and the injection timing such as the injection time can be set relatively easily and freely, so that the user can easily customize the operation.

  As described above, by adopting a configuration in which the solenoid valve 30 is controlled by using the electric power from the power generation means, the user can clean the air injection device more easily and easily while using the injection function. Can be provided.

  As described above, the air injection device according to the present invention and the vacuum cleaner using the same can inject air from the injection port into the suction chamber by the action of the suction force, and can cause the jet to act intermittently. Therefore, it is extremely useful as a device that can efficiently and easily clean a place that is difficult to clean by ordinary suction.
