[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a suction cleaner for injecting a water stream onto a person or a pet animal for cleaning, and particularly to locally sucking or rubbing the skin surface of the face or body with the water stream. TECHNICAL FIELD The present invention relates to a suction cleaning device that can also perform massage by performing a massage and a cleaning device including the suction cleaning device.

[0002]

2. Description of the Related Art In recent years, a suction cleaner for spraying a water stream discharged from a nozzle or the like onto a person or animal to wash or massage the same has been studied and developed. For example, Japanese Patent Application Laid-Open No. 08-196596 (hereinafter referred to as "A")
In the inside of the outer cylinder to which the water passage hole is attached, there is a pressurized fluid introduction hole which is arranged on the closed side at one end in the tangential direction of the inner circumference and through which the pressurized fluid is supplied, and a center. A water flow swirl chamber having an air intake port arranged at the rear end of the position and a water flow discharge port provided at the other end open side is installed, and a central boss opened facing the water flow discharge port is provided, A suction port opened toward the outside is installed on the other end side of the central boss, and a steam separating plate is provided at the opening of the central boss facing the water flow discharge port.
A massage suction cleaner including a front swirl chamber formed between an outer cylinder and a central boss is disclosed. Further, in Japanese Utility Model Laid-Open No. 63-74123 (hereinafter referred to as "B"), liquid supply holes are provided in a tangential direction along the peripheral wall of the mixing chamber and arranged so as to project from the rear part to the front part of the mixing chamber. There is disclosed a suction massage bubble jet device in which the discharge port of the air tube is positioned at the injection port of the mixing chamber and a plurality of protrusions are provided around the injection port.

[0003]

However, the above-mentioned conventional techniques have the following problems. (1) In the technique described in Japanese Patent Publication No. 1-A, a central boss provided with a gas-liquid separation plate is arranged facing the water flow outlet of a swirl chamber.
Since the flow-through plate is provided in the front swirl chamber formed between the central boss and the outer cylinder, the gas-liquid separation plate and the flow-through plate can be an obstacle, and the suction force due to the swirl flow can be effectively exerted. Can not. For this reason, the suction force of the swirl chamber is insufficient, and the massage effect is low near the suction port close to the skin, and it is difficult to suction and remove dirt such as fat accumulated in pores. It was (2) Since the gas sucked from the air intake collides with the water-water separator and the flow-through plate and is disturbed, it is difficult to generate fine and uniform bubbles in the water flow. There is a problem that a cleaning effect of removing bubbles by acting bubbles on the soiled part and a massage effect by stimulating the bubbles by colliding with the skin surface cannot be sufficiently obtained. (3) Since it does not have a mechanism for adjusting and controlling the amount, size, form, etc. of bubbles in the discharged water flow, it contains fine bubbles excellent in cleaning ability and massage ability depending on the use conditions. There was a problem that water flow could not be obtained. (4) Since the air / water separating plate, the flow-through plate, the central boss, and the like are incorporated inside, there is a problem in that the structure is complicated and maintenance is poor and productivity is low. (5) Since the air discharge port of the air pipe is arranged in the vicinity of the injection port of the mixing chamber in the technique described in the publication (B), the water flow in the swirling state in the mixing chamber and the air may come into direct contact with each other. In addition, the swirling water flow and air cannot be effectively contacted while maintaining a predetermined contact area to generate fine bubbles of a predetermined size and shape, and the massage effect and the cleaning effect are not sufficient. Had. (6) Although the central part of the mixing chamber has a low pressure due to the swirling liquid, a swirling flow is generated on the skin surface because the protrusions provided around the spray port form a gap between the spray port and the skin surface. The problem is that it is disturbed in the vicinity, and it is extremely difficult to form a low-pressure part, and it is difficult to suction and clean dirt such as fat accumulated in pores because the suction force is small near the injection port near the skin. Had. (7) Since there is no means to control the size and generation amount of fine bubbles formed in the water flow, more air than necessary is sucked from the air tube, and large bubbles are formed, resulting in sufficient massage effect and cleaning. There was a problem that the effect could not be obtained. (8) Since the space formed between the human body and the injection hole is formed by the protrusions provided around the injection port, the suction force is insufficient and the skin surface of the human body is sufficiently sucked to provide a massage effect. It had a problem that it could not. (9) There is a problem that it is difficult to effectively apply the water flow containing fine bubbles to the skin surface because the guide part for properly adjusting the discharge state of the jetted water flow is not provided. Was there.

The present invention solves the above-mentioned problems of the prior art by forming a swirling flow close to the skin surface and giving a strong suction force, and properly maintaining the state of the water flow including fine bubbles in the water flow. It is an object of the present invention to provide a suction cleaner having excellent cleaning effect and massage effect, and a cleaning device having a simple structure and excellent productivity and maintainability.

[0005]

In order to solve the above problems, a suction cleaner according to the present invention and a cleaning apparatus equipped with the same have the following configurations.

The suction cleaner according to claim 1 of the present invention comprises:
a. A container having a hollow portion having a shape that converges from the rear side toward the front side; b. A gas-liquid jetting hole provided at the front end of the body, c. A liquid introduction tube tangentially connected to the peripheral wall on the rear side of the container, d. And a gas-liquid jetting guide portion which is arranged on an outer peripheral portion of the gas-liquid jetting hole and which is widened in the jetting direction from the gas-liquid jetting hole.
With this configuration, the following effects can be obtained. (1) It is possible to connect a liquid introduction pipe of a suction cleaner to a water supply port such as a water supply or a discharge port side of a pump so that the liquid can flow from the liquid introduction pipe into the hollow portion of the container in a tangential direction of its peripheral wall. it can. The liquid that has flowed into the hollow portion moves toward the gas-liquid ejection hole while swirling along the peripheral wall surface that converges toward the front side of the hollow portion, and can be ejected from the gas-liquid ejection hole. The liquid flow (water flow) swirls along the inner wall surface of the gas-liquid jetting guide portion connected to the gas-liquid jetting hole and collides with the skin surface or the like arranged on the entire surface of the gas-liquid jetting guide portion. The central part of the swirling flow becomes a low pressure by the swirling motion of, and the skin surface and the like can be washed and massaged. (2) By bringing the edge of the gas-liquid jetting guide portion into contact with the skin surface to be washed or massaged, the skin surface is sucked from the front of the gas-liquid jetting guide portion that is decompressed by the swirling flow, and the massage effect is obtained. can get. Also, when air or the like is mixed in advance in the liquid supplied to the liquid introduction hole,
A gas shaft made of mixed air is formed in the center of the body inside the hollow part, and the tip and the peripheral part of this gas shaft are dispersed into fine bubbles in the water flow by the shearing force of the suction force of the water flow, and the skin surface It is possible to wash the skin surface more effectively by flowing out from the gap between the skin surface and the edge portion of the gas-liquid jetting guide portion together with the flowing water flow. (3) Since the swirl flow of the gas-liquid mixed fluid can be continued to the edge of the gas-liquid spout guide part where the water flow contacts the skin surface by the gas-liquid spouting guide part, the low pressure part generated by this swirling flow The skin surface can be effectively sucked in a wide range, and a high massage effect can be obtained. (4) Since the suction cleaner does not have any obstacle inside the water flow, it is possible to extremely efficiently generate the desired fine bubbles. (5) Since the structure is simple and the number of parts is small, it is excellent in productivity and maintainability. (6) When the gas-liquid jetting guide portion is used away from the skin surface, the suction washer can be effectively used as a shower without restricting the diffusion of the water flow jetted by the airflow jetting guide portion.

Here, as the shape of the body, a shell shape, a truncated cone shape, a hemispherical shape, a shape in which the rear wall is swollen (for example, a spherical shape), or the like is used. When using a shape in which the rear wall is bulged, part of the liquid that has flowed into the body from the liquid introduction tube is
Since it moves to the rear wall side and then reverses and moves to the gas-liquid jetting hole side while swirling around the gas axis, it is possible to form a jet flow having a straight-ahead property. Further, the rear wall can be formed in a hollow shape, which is opposite to the case where the rear wall is bulged, so that the movement of the water flow in the hollow portion can be changed. As the shape of the gas-liquid jetting guide, a truncated cone shape, a hemispherical shape, a dish shape, or the like is used, which stabilizes the jetted state of the gas-liquid mixed fluid, and It can be effectively applied to the skin surface. The gas-liquid ejection hole is a narrowed portion in which the body that converges from the rear side to the front side is narrowed, and it varies depending on the size of the body, the flow rate of the liquid supplied to the body, the pressure, etc. The diameter d is 1 / the maximum inner diameter D of the body
It is preferable to form 15 to 1/3 times, preferably 1/10 to 1/5 times. This is because as the diameter d of the gas-liquid ejection hole becomes smaller than 1/10 times the maximum inner diameter D of the vessel,
It tends to be difficult to secure the discharge flow rate of the liquid necessary for effectively washing and massaging the skin surface and the like.
This is because, as it exceeds / 5 times, a swirling flow of the liquid cannot be formed in the body and the suction force tends to be insufficient. These tendencies are smaller than 1/15 times,
Alternatively, if it exceeds 1/3, it becomes more remarkable, which is not preferable. The liquid introduction pipe is attached to the peripheral wall of the container whose discharge portion is formed in a substantially cylindrical shape in a tangential direction with respect to the peripheral wall. Thus, a swirl flow can be generated in the body by connecting the liquid introduction pipe to a supply port such as a pump or water supply and flowing pressurized water. Also,
The flow velocity of the liquid flowing into the container, the diameter of the liquid introduction pipe, the volume of the container, the diameter of the gas self-priming hole, etc. are the required suction force, the flow velocity of the swirling flow, the amount of fine bubbles and particles generated in the water flow. It is appropriately selected depending on the shape such as the diameter.

The suction cleaning device according to a second aspect is the first aspect.
In the invention described in (1), the rear wall of the container is configured to have a gas self-priming hole formed by opening at a position eccentric from a shaft axis of the container or a gas axis formed in the container. . With this configuration, in addition to the operation of claim 1, the following operation can be obtained. (1) The gas axis formed in the central part of the body forms fine bubbles at the rod-shaped tip and the peripheral part due to the shearing force of the water flow, and along with the water flow that hits the skin surface, the skin surface and the gas-liquid ejection guide part The skin surface can be washed by flowing out from the gap with the edge. (2) Since fine bubbles are mixed in the swirling flow that collides with the skin surface, and the fine bubbles adhere to the skin surface and burst,
It is possible to stimulate and activate the skin surface and obtain a high massage effect. (3) Since the gas can be directly sucked into the hollow portion through the gas self-priming hole, it can be easily used without using a pump or the like by connecting to the water supply port of the water supply. (4) By including fine air bubbles in the water flow, the fine air bubbles can be made to reach the vicinity of the hair root, and the fine air bubbles are brought into shock contact with the skin surface, and the frictional action and the action at the time of bursting of the fine air bubbles. It can wash away oxidized sebum and old keratin on the skin surface. (5) Due to the swirling motion of the water flow in the vessel, a low pressure portion is formed at the central portion of the swirling flow, that is, at the axis of the vessel, and air is sucked from the gas self-priming hole toward the low pressure portion to cause the gas-liquid jetting hole. A gas axis extending in a rod shape toward the center is formed in the body.
At this time, by disposing the gas self-priming hole at a position eccentric from the axis of the body, it is possible to vibrate the tip of the gas axis and more effectively generate fine bubbles. By adjusting the amount of eccentricity, the shape, size, etc. of the gas axis can be subtly changed to obtain a water flow containing predetermined fine bubbles in which the cleaning effect and the massage effect are optimized.

The flow velocity of the liquid flowing into the container, the diameter of the liquid introduction tube, the volume of the container, the diameter of the gas self-priming hole, etc. are appropriately determined depending on the suction force by the water flow and the form such as the amount and particle size of fine bubbles. To be selected. That is, when the opening diameter of the gas self-priming hole is increased, the amount of gas sucked from the gas self-priming hole is large and the force for sucking the skin surface is small, and when the opening diameter of the gas self-priming hole is small, the gas self-priming hole is small. The amount of gas inhaled is small, and the force of sucking the skin surface becomes large. The diameter of the gas self-priming hole varies depending on the pressure of water supplied from the liquid introduction pipe, the flow rate, the size and shape of the body, but is 0.01 to 0.5 mm, preferably 0.0.
It is desirable to set it in the range of 3 to 0.1 mm. this is,
As the diameter of the gas self-priming hole becomes smaller than 0.03 mm, the amount of air that can be supplied to the body tends to be insufficient, and conversely, as it exceeds 0.1 mm, the diameter of the bubbles diffused in the water flow increases, The cleaning effect and massage effect due to fine air bubbles tend to be impaired.
60 mm, axial length 40-60 mm, diameter of gas-liquid ejection hole is 5
This is because these tendencies become more remarkable when it is smaller than 0.01 mm or larger than 0.5 mm in the case of 10 mm.

The suction cleaner according to claim 3 is the same as that according to claim 2.
In the invention described in (1), the gas shaft formed in the body of the body is attached by being screwed or fitted to a screw portion or a fitting portion formed in the rear wall of the body. Is provided so as to be rotatable about an eccentric position as a center, and the gas self-priming hole is formed at a position eccentric from a rotation axis of the rotating member. With this configuration, in addition to the operation of claim 2, the following operation can be obtained. (1) The rotating member is rotatably covered on the rear wall of the body about a position eccentric from the central axis of the body, and the gas self-priming hole is eccentric from the rotating shaft of the rotating member. Since it is formed, by rotating or rotating the rotating member, it is possible to adjust the area of the portion where the projected cross section of the gas shaft formed in the body on the rear wall and the gas self-priming hole overlap. it can. The suction resistance of the gas self-priming hole can be changed by increasing or decreasing the area of this overlapping portion to adjust the amount of gas sucked from the gas self-priming hole. (2) When liquid is supplied in the tangential direction of the body from the liquid introduction hole of the body, a swirling flow is formed to reduce the pressure in the central portion of the body, and a gas is introduced from the gas self-priming hole arranged on the rear wall of the body. Is sucked. In this way, the gas axis made of the sucked air can be formed in the center of the body. The form of this gas axis is the pressure and flow rate of water supplied from the liquid introduction pipe,
Although it changes depending on the temperature and the like, the relative position between the central axis of the body 2 and the gas self-priming hole 5 can be changed and adjusted by rotating the rotating member at a predetermined angle. (3) By rotating the rotating member, the amount of gas sucked into the hollow portion can be adjusted, so that the jetting amount of fine bubbles and the suction force on the skin surface can be subtly changed. Excellent in performance. Here, the rotating member is a lid-like member that is covered with the rear wall of the body in a sealed state via a screw portion or a fitting portion, and a rotating shaft provided on the rear wall of the body. It can rotate at a predetermined angle with respect to. It is desirable to set the position of the rotating shaft of the rotating member to a position eccentric to the axis of the body or a gas axis formed in the body within a range of a distance of 1 to 10% of the radius of the body. . This depends on the diameter of the gas self-priming hole to be applied and the size of the body, but if the eccentricity is less than 1%, the amount of air sucked from the gas self-priming hole by adjusting the rotation angle of the rotating member. This is because it becomes difficult to adjust the rotation angle. On the other hand, if it exceeds 10%, the space for rotating the rotation member on the rear wall of the body is reduced and it becomes difficult to perform a predetermined rotation operation. Appears, which is not preferable. The gas axis is a gathering part of gas that is formed in the central part of the body by the swirling water flow in the body, and the shape of the body formed in the position of the liquid introduction tube, the elliptical shape, etc. The formed position may vary depending on the position of the hole and the like.

The suction cleaner according to claim 4 is the same as claim 2.
Or the tank portion which is provided on the rear wall of the container or the rotating member and supplies gas through the gas self-priming hole, and a gas introduction hole provided in the tank portion. And is configured. With this configuration, the following action is obtained in addition to the action described in claim 2 or 3. (1) Since the tank portion is provided, the outside air does not flow directly into the body from the gas self-priming hole, and the suction resistance of the sucked air can be increased, so that the diameter of the gas self-priming hole can be increased. Even if a large amount of gas is not sucked in, the gas-liquid jetting guide portion can maintain the force of sucking the skin surface, and a high massage effect can be obtained. (2) Since the external pressure fluctuation is mitigated by providing the large-capacity tank part, it is possible to stabilize and facilitate the control of the size, shape, and generation amount of the fine bubbles generated in the water flow, and improve the operability. Excel. (3) Since the diameter of the gas self-priming hole can be increased,
Excellent in maintainability because malfunctions due to clogging with dust and water stains are less likely to occur. Here, as the shape of the tank portion, a cylindrical shape, a hemispherical shape, or the like is used. The size and number of the tank holes are appropriately selected according to the required suction force, swirling flow velocity, the number and particle size of the fine bubbles.

The suction cleaner according to claim 5 is the same as claim 1.
In the invention according to, the tip end side is reduced in diameter and protrudes from the rear wall side of the body, and the tip end opening portion is disposed inside the gas-liquid ejection hole, and the water flow ejection nozzle portion is provided in the water flow ejection nozzle portion. A plug-like, conical, or inverted conical water flow adjusting member disposed near the tip of the nozzle via an inserted rod-shaped supporting member, and a base end side of the supporting member that can be moved forward or backward or fixed to support it. And a position adjustment fixing portion provided on the rear wall side of the body. With this configuration,
In addition to the actions described in claim 1, the following actions are provided. (1) A portion of tap water or hot water supplied from the liquid introduction pipe or tap water or hot water supplied from a pipe of another system is supplied to the vicinity of the inside of the gas-liquid ejection hole via the water jet nozzle. It can be directly ejected in a high state and has excellent cleaning and massage properties. (2) Since the water flow adjusting member is provided inside the tip of the water jet nozzle, the water jet adjusting member is moved forward or backward or fixed at a predetermined position to properly maintain the jet angle of the water jet and the gas-liquid dispersion state. be able to. For example, when the water flow adjusting portion is formed in the shape of an inverted cone whose diameter increases, the water flow is ejected in the shape of an inverted figure toward the jet outlet of the nozzle. It is possible to join the swirling flow that swirls and converges from the outer periphery of the shape. Therefore, both jetting forces can be suppressed and jetted into large water droplets, or both can be synergistically jetted into fine water droplets, which can be adjusted according to the washing and massage conditions. (3) Especially when the water to be supplied to the flow jet nozzle is heated to be hot water, the dissolved amount of gas that can be dissolved in water decreases according to Henry's law and becomes supersaturated. A large amount of dissolved gas can be released by passing it through the pressure part (low pressure part), whereby a cleaning liquid or a massage liquid containing many fine bubbles can be obtained. Here, the water jet nozzle is installed in a state where the tip side is inserted from the rear wall side of the body, and tap water or hot water is supplied at a predetermined flow rate through a branch pipe branched from the liquid introduction pipe or another pipe system. It has become so. The flow rate ratio (A / B) between the flow rate A supplied from the water jet nozzle and the flow rate B supplied from the liquid introducing pipe connected to the vessel wall to form a swirl flow is 0.1 to 0.8. ,
It is desirable to set it in the range of 0.2 to 0.5. This depends on the amount of dissolved gas in tap water and its temperature, but as the flow rate ratio (A / B) becomes less than 0.2, the flow rate directly supplied to the skin surface decreases, and The pressure massage effect tends to deteriorate, and conversely, as the value exceeds 0.5, the friction massage effect due to the swirling flow tends to decrease, and these tendencies become smaller than 0.1 or exceed 0.8. This is because it becomes more remarkable. The tip of the water flow adjusting member is formed in an inverted conical shape or the like, and by advancing or retracting this tip position to a predetermined position or by fixing it, the interval with the tip of the nozzle is defined, and the cleaning is ejected from the gas-liquid ejection hole. It is possible to make delicate adjustments such as the flow rate of water, the jetting angle, and the foaming state.

The suction cleaner according to claim 6 is the same as that according to claim 1.
In the invention described in any one of 1 to 5, an inclined portion that expands at a predetermined angle toward the ejection side is formed on the inner peripheral wall of the gas-liquid ejection hole, and is connected to the front of the inclined portion. And a flat portion. With this configuration, claim 1
In addition to the action of any one of the items 5 to 5, the following actions are obtained. (1) Since the inner peripheral wall of the gas-liquid ejection hole has an inclined portion that expands at a predetermined angle toward the ejection side, the range in which the water flow containing fine bubbles or bubble nuclei before becoming fine bubbles diffuses The inside of the water flow can be depressurized only within a predetermined angle, and the partial depressurization can effectively promote the growth of bubble nuclei into fine bubbles. (2) When it is used as a shower, since it has a flat portion formed in front of the inclined portion so as to be connected to it, it is possible to prepare water droplets ejected at this flat portion and to contain a large amount of fine bubbles. The water droplets can be stably supplied, and the water droplets can be concentrated in the central portion in the ejection direction. (3) The angle θ in the inclined portion, the length A in the jet direction in the jet direction, and the length B in the jet direction in the flat portion are combined and adjusted according to the quality of water to be supplied, the pressure, the flow rate, the temperature, and the like. Thus, the size of the fine bubbles diffused in the water flow, the aggregate form of the bubbles, and the like can be subtly changed. Since the cleaning effect and the massage effect due to the fine bubbles vary depending on the factors such as the form of the fine bubbles, it is possible to set the optimized value combination (θ, A, B) based on the experiment.

Here, the angle θ of the inclined portion varies depending on the size of the vessel used, the flow rate and pressure of water to be supplied, and the lengths A and B, but is in the range of 50 to 120 degrees, preferably 73 to 79 degrees. Is desirable. This is because as the angle θ of the inclined portion becomes smaller than 73 degrees, the distance to the skin surface increases and the suction force tends to decrease. On the contrary, as the angle θ exceeds 79 degrees, the water flow spreads widely and This is because there is an increasing tendency to be unable to concentrate in the central part.
Further, these tendencies are not preferable because the angle θ of the inclined portion becomes smaller than 50 ° or exceeds 120 °. It is preferable that the lengths A and B of the inclined portion and the flat portion in the ejection direction be 0.5 to 1.2 times the diameter d of the minimum diameter portion of the gas-liquid ejection hole. This is because when the lengths A and B of the inclined portion and the flat portion are smaller than 0.5 times the diameter d of the minimum diameter portion, the effect of suppressing the direction of the water flow is reduced, and when it exceeds 1.2 times, the suction force is increased. Because it will fall. That is, when the suction cleaning device is used as a shower, the water droplets ejected from the gas-liquid ejection hole tend to be hollow at the center portion of the water flow because they are ejected in a swirling state. By providing the flat portion and the inclined portion set to the height, it is possible to concentrate the ejected water droplets on the central portion, so that the water droplets can be applied to the skin surface in an averaged state.

The suction cleaner according to claim 7 is the same as claim 1.

With this configuration, the following actions can be obtained in addition to the actions according to any one of claims 1 to 6. (1) When the front edge of the gas-liquid jetting guide is applied to the skin surface and jetted, the swirling liquid hitting the skin is closer to the gas axis of the central negative pressure portion than to the outflow side. Flip to. The skin of the inverted negative pressure portion and the central negative pressure portion can be sucked in a wide range. (2) Even if the front end of the gas-liquid jetting guide portion is strongly pressed against the skin surface, the swirling flow can be flown out of the gas-liquid jetting guide portion from the outflow portion, so that the water flow continues to the skin surface. Can be flushed. (3) Since it is possible to provide a plurality of outflow portions with respect to the gas-liquid ejection guide portion, it is possible to effectively generate a swirling flow or to complicate the flow to enhance the massage effect. Here, the outflow portion is an opening or a notch formed in a rectangular shape or a circular shape penetrating the front and back surfaces of the gas-liquid ejection guide portion, and a part of the water flow introduced into the gas-liquid ejection guide portion. Is a portion configured to flow to the outside, and the flow state in the gas-liquid jetting guide portion can be adjusted by the arrangement pattern, the opening area thereof, and the like.

With this configuration, the following action is obtained in addition to the action according to any one of claims 1 to 7. (1) Since the liquid flowing out from the outflow portion moves rearward on the side opposite to the skin surface side, it is possible to prevent the water stream from splashing on the face or the like. (2) When a liquid recovery pipe is attached to the scattering prevention part, it can be used without polluting the bathroom or washroom. Here, the scattering prevention part is a wall-shaped part provided so as to project to the rear side along the peripheral edge of the gas-liquid ejection guide part, whereby the liquid flowing out from the outflow part opened in the gas-liquid ejection guide part. Has a function of guiding the gas-liquid jetting guide portion rearward of the front end portion.

The hemispherical peripheral portion is provided with an outflow restricting portion that shields the outflow portion of the gas-liquid ejection guide portion. With this configuration, in addition to the action of claim 9, the following action is obtained. (1) Since the outflow control part is rotatably provided at the peripheral edge of the gas-liquid ejection guide part, the outflow part communicating with the water flow recovery part may be shielded depending on the usage conditions such as a bathroom or a washroom.

It may be a notch.

The operation of the suction cleaner of the first embodiment having the above-described structure will be described with reference to the drawings. FIG. 3 is a side sectional view of a main part showing a usage state of the suction cleaner according to the first embodiment. In FIG.
1 is a suction cleaner according to the first embodiment, 2 is a body, 2a
1 is a hollow part, 3 is a gas-liquid jetting hole, 4 is a liquid introducing pipe, 5 is a gas self-sucking hole, 6 is a gas-liquid jetting guide part, and 7 is an outflow part. These are the same as those in FIGS. 1 and 2. Therefore, the same reference numerals are given and the description thereof is omitted. H is the skin surface of the user of the suction cleaner 1, W is the air sucked from the gas self-priming hole 5 into the hollow portion 2a, and the tip extends toward the gas-liquid jetting hole 3 and is formed into a rod shape. It is the gas axis (low pressure part). The form of the gas axis W formed in the container body 2 changes depending on the pressure, flow rate, temperature, etc. of water supplied from the liquid introduction pipe 4,
It can also be greatly changed depending on the size of the opening of the gas self-priming hole 5 and the relationship between the central axis of the body 2 and the position of the gas self-priming hole 5. In the first embodiment, the gas self-priming hole 5
Has an opening diameter of about 0.01 to 0.1 mm, and the gas self-priming hole 5 is arranged at a position eccentric about 1 to 5 mm from the central position of the rear wall of the container 2 (center axis of the container). The gas shaft is hollow 2
It was formed in a. Further, the shape and size of the gas axis can be delicately changed by the amount of eccentricity, and it is possible to obtain a water flow containing predetermined fine bubbles that can optimize the cleaning effect and the massage effect. First, the liquid introduction pipe 4 of the suction cleaner 1 is connected to the water supply port of the home or the discharge port side of the pump via a hose or the like, and the liquid is introduced from the liquid introduction pipe 4 into the hollow portion 2a of the container 2 in the tangential direction. Inflow. The liquid thus flowing into the hollow portion 2a becomes a gas-liquid mixed fluid while swirling along the wall surface of the hollow portion 2a while sucking air from the gas self-priming hole 5, and becomes a gas-liquid jetting guide from the gas-liquid jetting hole 3. Move to Part 6. The gas-liquid mixed liquid collides with the skin surface H while swirling along the inner wall surface of the gas-liquid jetting guide portion 6,
The outflow portion 7 flows out of the suction cleaner 1.

Is formed, and the skin surface H on the front side of the gas-liquid jetting guide portion 6 is sucked. Since the tip of the gas axis W decenters the position of the gas self-priming hole 5, the tip of the gas axis W is torn off by shearing in front of the skin surface H while swirling, and becomes fine bubbles that diffuse into the swirling water flow. In this way, the water flow including the fine bubbles flows along the skin surface H, is reversed in the gas axis W direction at the edge of the gas-liquid jetting guide portion 6, is further reversed around the gas axis W, and flows out from the outflow portion 7. By effectively performing such a reversing motion of the water flow, generation of fine bubbles in the liquid can be promoted, and the skin surface H can be continuously and strongly suction-washed over a wide range. Further, due to the interaction between the fine bubbles contained in the water stream and the dirt such as old keratin on the skin surface, the dirt can be removed from the skin surface and the skin surface can be effectively washed.

The water flow is mild and comfortable to use. (3) A gas axis is formed in the body 2 by the air sucked through the gas self-priming hole 5, and a predetermined amount is generated in the water flow by the interaction between the gas axis and the swirling flow in the hollow portion 2a. It has excellent detergency because it can effectively generate fine bubbles of the form. (4) Fine bubbles are mixed in the swirling flow that collides with the skin surface H, and the fine bubbles adhere to the skin surface H and explode, thereby imparting a massage effect by a low frequency to effectively make the skin surface H effective. Can be massaged. (5) Since the suction cleaner 1 does not include extra constituent elements in the hollow portion 2a and has a small number of parts and a simple structure, it is excellent in productivity and maintainability. (6) When the tip of the gas-liquid jetting guide portion 6 is separated from the skin surface H, the swirling flow flies as water droplets, and thus it can be used as a shower containing fine bubbles and is excellent in convenience.

The tank portion 23 is a liquid storage portion that is formed on the rear wall of the body 2 and is formed in a cylindrical shape, and communicates with the hollow portion 2a through the gas self-priming hole 5 ′ formed on the rear wall. ing.
The tank portion 23 is formed to have substantially the same diameter as the body 12, and has a volume of about 1/20 to 1/4 of the volume of the body 2. Although the tank portion 23 is bonded to the rear wall of the container body 2 with an adhesive or the like, it may be integrally formed with the container body. The tank hole 24 is formed in the upper portion of the tank portion 23, has a hole diameter of about 0.5 to 5 mm, and can suck outside air or the like through the water stored in the tank portion 23.

The operation of the suction cleaner 60 constructed as described above will be described. A liquid having a predetermined flow rate and pressure is supplied from the liquid introduction pipe 64 to the hollow portion 62 of the container 61 in the tangential direction. At this time, the liquid flowing into the hollow portion 62 is
The low-pressure portion is formed at the center of the body by swirling along the wall surface of the hollow portion 62. By this low pressure portion, air is sucked from the gas self-priming hole 65 arranged near the center of the rear wall of the container 61, and a gas axis is formed in the low pressure portion inside the hollow portion 62. Micro bubbles are generated in the liquid by the mutual movement of the gas axis and the swirling flow. In this way, the water flow containing the fine air bubbles is directed to the inclined portion 63a and the flat portion 63b formed on the inner wall of the gas-liquid ejection hole 63.
It moves along the gas-liquid jetting guide portion 66 via the nozzle and is discharged from between the peripheral edge of the gas-liquid jetting guide portion 66 and the skin surface or the like. In addition, when the gas-liquid jetting guide portion 66 is provided with the outflow portion 7 in which a notch or an opening is formed, even if the front end portion of the gas-liquid jetting guide portion is strongly pressed against the skin surface, the swirl flow is generated. It is possible to let the gas flow out of the gas-liquid jetting guide portion 66 from outside.

And is discharged from the outflow section 7. Since such low-pressure zones and high-pressure zones can be alternately formed on the skin surface H, the blood circulation state of the skin can be promoted and dirt on the skin surface can be effectively removed.

Since the suction cleaner 60 of the sixth embodiment is constructed as described above, the following operation is obtained in addition to the operation obtained in the first embodiment. (1) Since the inner peripheral wall of the gas-liquid ejection hole 63 has the inclined portion 63a that expands at a predetermined angle toward the ejection side, the water flow containing fine bubbles or bubble nuclei before becoming fine bubbles diffuses. The range can be limited within a predetermined angle to reduce the pressure in the water flow, and this partial reduction in pressure can effectively promote the growth of bubble nuclei into fine bubbles. (2) When it is used as a shower, it has a flat portion 63b formed in front of the inclined portion 63a so as to be connected to it, so that water droplets ejected at this flat portion 63b can be adjusted and fine bubbles can be formed. It is possible to stably supply a large amount of water droplets. Moreover, the water droplets ejected can be collected in the central portion. (3) The angle θ of the inclined portion 63a and the length A in the ejection direction of the inclined portion 63a and the length B of the ejection portion in the flat portion 63b are used under conditions such as the quality of water to be supplied, the pressure, the flow rate, and the temperature, such as a bathtub and a pool. Depending on the usage conditions such as the side, they can be combined and adjusted to an appropriate range, and the size of the fine bubbles and the aggregate form of the bubbles can be subtly changed to enhance the cleaning effect and massage effect by the fine bubbles. .. (4) A pressure distribution P in which low-pressure zones and high-pressure zones alternate in an annular shape can be formed on the skin surface H by the flow Q of the gas-liquid mixed fluid via the outflow portion 7, whereby the skin surface It stimulates blood circulation and promotes its blood circulation, and can effectively remove dirt on the skin surface.

According to the suction cleaner of the first aspect of the present invention, the following effects can be obtained. (1) It is possible to connect a liquid introduction pipe of a suction cleaner to a water supply port such as a water supply or a discharge port side of a pump so that the liquid can flow from the liquid introduction pipe into the hollow portion of the container in a tangential direction of its peripheral wall. it can. The liquid that has flowed into the hollow portion moves toward the gas-liquid ejection hole while swirling along the peripheral wall surface that converges toward the front side of the hollow portion, and can be ejected from the gas-liquid ejection hole. The liquid flow (water flow) swirls along the inner wall surface of the gas-liquid jetting guide portion connected to the gas-liquid jetting hole and collides with the skin surface or the like arranged on the entire surface of the gas-liquid jetting guide portion. The central part of the swirling flow becomes a low pressure by the swirling motion of, and the skin surface and the like can be washed and massaged. (2) By bringing the edge of the gas-liquid jetting guide portion into contact with the skin surface to be washed or massaged, the skin surface is sucked from the front of the gas-liquid jetting guide portion that is decompressed by the swirling flow, and the massage effect is obtained. can get. Also, when air or the like is mixed in advance in the liquid supplied to the liquid introduction hole,
A gas shaft made of mixed air is formed in the center of the body inside the hollow part, and the tip and the peripheral part of this gas shaft are dispersed into fine bubbles in the water flow by the shearing force of the suction force of the water flow, and the skin surface It is possible to wash the skin surface more effectively by flowing out from the gap between the skin surface and the edge portion of the gas-liquid jetting guide portion together with the flowing water flow. (3) Since the swirl flow of the gas-liquid mixed fluid can be continued to the edge of the gas-liquid spout guide part where the water flow contacts the skin surface by the gas-liquid spouting guide part, the low pressure part generated by this swirling flow The skin surface can be effectively sucked in a wide range, and a high massage effect can be obtained. (4) Since the suction cleaner does not have any obstacle inside the water flow, it is possible to extremely efficiently generate the desired fine bubbles. (5) Since the structure is simple and the number of parts is small, it is excellent in productivity and maintainability. (6) When the gas-liquid jetting guide portion is used away from the skin surface, the suction washer can be effectively used as a shower without restricting the diffusion of the water flow jetted by the airflow jetting guide portion.

According to the suction cleaner of the second aspect, the following effects can be obtained in addition to the effect of the first aspect. (1) The gas axis formed in the central part of the body forms fine bubbles at the rod-shaped tip and the peripheral part due to the shearing force of the water flow, and along with the water flow that hits the skin surface, the skin surface and the gas-liquid ejection guide part The skin surface can be washed by flowing out from the gap with the edge. (2) Since fine bubbles are mixed in the swirling flow that collides with the skin surface, and the fine bubbles adhere to the skin surface and burst,
It is possible to stimulate and activate the skin surface and obtain a high massage effect. (3) Since the gas can be directly sucked into the hollow portion through the gas self-priming hole, it can be easily used without using a pump or the like by connecting to the water supply port of the water supply. (4) By including fine air bubbles in the water flow, the fine air bubbles can be made to reach the vicinity of the hair root, and the fine air bubbles are brought into shock contact with the skin surface, and the friction effect and the action when the fine air bubbles burst It can wash away oxidized sebum and old keratin on the skin surface. (5) Due to the swirling motion of the water flow in the vessel, a low pressure portion is formed at the central portion of the swirling flow, that is, at the axis of the vessel, and air is sucked from the gas self-priming hole toward the low pressure portion to cause the gas-liquid jetting hole. A gas axis extending in a rod shape toward the center is formed in the body.
At this time, by disposing the gas self-priming hole at a position eccentric from the axis of the body, it is possible to vibrate the tip of the gas axis and more effectively generate fine bubbles. By adjusting the amount of eccentricity, the shape, size, etc. of the gas axis can be subtly changed to obtain a water flow containing predetermined fine bubbles in which the cleaning effect and the massage effect are optimized.

According to the suction cleaner of the third aspect, the following effects can be obtained in addition to the effect of the second aspect. (1) The rotating member is rotatably covered on the rear wall of the body about a position eccentric from the central axis of the body, and the gas self-priming hole is eccentric from the rotating shaft of the rotating member. Since it is formed, by rotating or rotating the rotating member, it is possible to adjust the area of the portion where the projected cross section of the gas shaft formed in the body on the rear wall and the gas self-priming hole overlap. it can. The suction resistance of the gas self-priming hole can be changed by increasing or decreasing the area of this overlapping portion to adjust the amount of gas sucked from the gas self-priming hole. (2) When liquid is supplied in the tangential direction of the body from the liquid introduction hole of the body, a swirling flow is formed to reduce the pressure in the central portion of the body, and a gas is introduced from the gas self-priming hole arranged on the rear wall of the body. Is sucked. In this way, the gas axis made of the sucked air can be formed in the center of the body. The form of this gas axis is the pressure and flow rate of water supplied from the liquid introduction pipe,
Although it changes depending on the temperature and the like, the relative position between the central axis of the body 2 and the gas self-priming hole 5 can be changed and adjusted by rotating the rotating member at a predetermined angle. (3) By rotating the rotating member, the amount of gas sucked into the hollow portion can be adjusted, so that the jetting amount of fine bubbles and the suction force on the skin surface can be subtly changed. Excellent in performance.

According to the suction cleaning device of the fourth aspect, the following effects can be obtained in addition to the effects of the second or third aspect. (1) Since the tank portion is provided, the outside air does not flow directly into the body from the gas self-priming hole, and the suction resistance of the sucked air can be increased, so that the diameter of the gas self-priming hole can be increased. Even if a large amount of gas is not sucked in, the gas-liquid jetting guide portion can maintain the force of sucking the skin surface, and a high massage effect can be obtained. (2) Since the external pressure fluctuation is mitigated by providing the large-capacity tank part, it is possible to stabilize and facilitate the control of the size, shape, and generation amount of the fine bubbles generated in the water flow, and improve the operability. Excel. (3) Since the diameter of the gas self-priming hole can be increased,

For example, when the water flow adjusting portion is formed in the shape of an inverted cone whose diameter increases, the water flow is ejected in the shape of an inverted figure toward the jet outlet of the nozzle. It is possible to join the swirling flow that swirls and converges from the outer periphery of the shape. Therefore, both jetting forces can be suppressed and jetted into large water droplets, or both can be synergistically jetted into fine water droplets, which can be adjusted according to the washing and massage conditions. (3) Especially when the water to be supplied to the flow jet nozzle is heated to be hot water, the dissolved amount of gas that can be dissolved in water decreases according to Henry's law and becomes supersaturated. A large amount of dissolved gas can be released by passing through the pressure part (low pressure part), and a cleaning liquid or a massage liquid containing a lot of fine bubbles can be obtained.

(2) When it is used as a shower, since it has a flat portion formed in front of the inclined portion so as to be connected to it, it is possible to prepare water droplets ejected at this flat portion and to contain a large amount of fine bubbles. The water droplets can be stably supplied, and the water droplets can be concentrated in the central portion in the ejection direction. (3) The angle θ in the inclined portion, the length A in the jet direction in the jet direction, and the length B in the jet direction in the flat portion are combined and adjusted according to the quality of water to be supplied, the pressure, the flow rate, the temperature, and the like. Thus, the size of the fine bubbles diffused in the water flow, the aggregate form of the bubbles, and the like can be subtly changed. Since the cleaning effect and the massage effect due to the fine bubbles vary depending on the factors such as the form of the fine bubbles, it is possible to set the optimized value combination (θ, A, B) based on the experiment.

According to the suction cleaner of the seventh aspect, in addition to the effect of any one of the first to sixth aspects, the following effects can be obtained.

(1) Since the water flow recovery unit is provided, the cleaning water and the like do not largely scatter around, and the surroundings can be prevented from being polluted, which is hygienic. (2) Since the air-liquid jetting guide portion is brought into contact with the skin surface to form a closed system in which water flows when jetting hot water, the pressure on the skin surface due to the jet stream is increased and a good cleaning effect is obtained. A massage effect is obtained.

According to the suction cleaning device of the tenth aspect,
In addition to the effect of claim 9, the following effect is provided. (1) Since the outflow control part is rotatably provided at the peripheral edge of the gas-liquid ejection guide part, the outflow part communicating with the water flow recovery part may be shielded depending on the usage conditions such as a bathroom or a washroom. It can be used in an open state. It can be used as a shower in which fine air bubbles are mixed by fitting the outflow restricting portion to the gas-liquid ejection guide portion, or can be used as a suction cleaning device in an open state, which is excellent in operability and versatility. (2) Since the flowing water shield is attached via the hinge, it can be stored compactly in a state where the flowing water shield is fitted to the gas-liquid jetting guide, and it is convenient without fear of running out.
