Description

  The present invention relates to an umbrella dewatering machine that removes water droplets adhering to an umbrella cloth with air.

  In recent years, an umbrella dewatering machine that removes water droplets adhering to an umbrella cloth with air has been used. Using an umbrella dewatering machine when entering a building on a rainy day makes it difficult for water drops to drip from the umbrella in the building.

  Such an umbrella dewatering machine removes water droplets by blowing air onto the front surface of a closed umbrella cloth. However, the umbrella cloth is in a slack state when the umbrella is closed. If the slack of the umbrella cloth is heavy, air will not reach the area and water droplets will tend to remain. For this reason, it is necessary to eliminate the overlap of the sagging of the umbrella cloth when removing water droplets by air.

  About cancellation | release of the overlap of the slack of an umbrella cloth, what is disclosed by patent document 1, for example is equipped with the air blower which has an air blowing function, and conveys the air sent out from an air blower separately by two ducts. The air carried in one duct is blown onto the front surface of the umbrella cloth to remove water droplets adhering to the front surface of the umbrella cloth. The air carried in the other duct is blown into the inside of the umbrella, spreading the sagging of the umbrella cloth and eliminating the sagging overlap.

JP-A-4-28991

  However, in such an umbrella dewatering machine, two systems of a system for expanding the slack of the umbrella cloth and a system for removing water droplets are required as an air blowing system. Therefore, nozzles and ducts are required in each system, and the structure becomes complicated. Manufacturing complexity and maintenance costs increase due to the complexity of the structure.

  Moreover, since the system for expanding the slack of the umbrella cloth and the air for two systems for removing water droplets are necessary, the required air volume increases and the blower becomes larger. The increase in size of the blower increases the power consumption and the operation sound of the blower.

  The present invention has been made in view of the above-mentioned problems, and reuses air used for removing water droplets in order to widen the slack of umbrella cloth, thereby improving water removal performance without complicating the air blowing system. An object of the present invention is to provide an umbrella dewatering machine that can suppress manufacturing cost, power consumption, and operation noise.

  In order to solve the above problems, an umbrella dewatering apparatus according to the present invention is a umbrella dewatering machine that removes water droplets attached to an umbrella cloth, and a box that houses a closed umbrella inserted from the tip into an insertion hole. And the air jet part that blows air from the stone protrusion side of the umbrella inside the box and generates air flow from the stone protrusion side to the dew side, and the insertion hole side of the box body. An air guiding portion that changes the direction of the air from which water droplets on the surface have been removed and guides the air to the inside of the umbrella.

  According to the present invention, the direction of the air is changed by the guide portion provided in the box, and the air used for removing the water droplets is reused to widen the slack of the umbrella cloth without complicating the blower system. In addition, the water removal performance can be improved. Moreover, since the ventilation system is not complicated, the manufacturing cost, noise, power consumption, etc. of the umbrella dewatering machine can be suppressed.

Embodiment 1 FIG.
FIG. 1 is an external perspective view of an umbrella water remover 2 according to the first embodiment. FIG. 2 is a cross-sectional view of the umbrella water remover 2. The umbrella water remover 2 has a box 4 and a blower (blower unit) 8 and is generally configured.

  The umbrella 20 from which water droplets are removed by the umbrella dewatering machine 2 includes, for example, an intermediate rod 20a, a hand (handle portion) 20b, a stone bump 20c, a main bone 20d, and an umbrella cloth 20e. The middle rod 20 a is a shaft member that is located at the center of the umbrella 20 with the hand 20 b and the stone protrusion 20 c attached to both ends thereof. The hand 20b is a handle portion possessed by the user of the umbrella 20. The stone bump 20c is attached to the tip of the umbrella 20 and has a function of collecting the umbrella cloth 20e. A plurality of the main bones 20d are pivotally supported in the vicinity of the stone protrusion 20c of the middle rod 20a. The umbrella cloth 20e is a cloth-like member that covers the space between the main bones 20d. The tip (free end) side of the main bone 20d is referred to as a tip 20f. A detailed description of the opening / closing mechanism and the like of the umbrella 20 is omitted.

  In the present application, the front surface of the umbrella cloth 20e refers to a surface that receives rain when the umbrella 20 is inserted, and a surface that faces outward when the umbrella 20 is closed. The back surface of the umbrella cloth 20e refers to a surface opposite to the front surface. Moreover, the inside of the umbrella 20 means the area | region enclosed in the umbrella cloth 20e in the umbrella 20 of the closed state.

  The box 4 has a function as a housing that covers the entire umbrella water remover 2. The box 4 is made of a sheet metal or the like on a thin plate, and includes a main body (main body portion) 10 and a lid (lid portion) 12. The main body 10 is formed with a take-out opening 11 for taking out the umbrella 20 from a water removal chamber 14 described later. The take-out opening 11 is opened larger than the spread of the tip 20f so that the tip 20f and the like are not caught when the umbrella 20 is taken out from the water removal chamber 14.

  The lid 12 is attached to the main body 10 so as to cover the extraction opening 11. The main body 10 and the lid 12 are connected by a hinge 21 so as to be opened and closed. A body-side recess 10a and a lid-side recess 12a are formed at the boundary between the body 10 and the lid 12, and the umbrella 20 can be inserted from the tip (stone bump 20c) side by the body-side recess 10a and the lid-side recess 12a. The insertion hole 22 is configured. The main body 10 and the lid 12 can be divided on the surface including the insertion hole 22. The insertion hole 22 only needs to be able to insert the umbrella 20, and is formed smaller than the extraction opening 11. The insertion hole 22 is an opening facing obliquely upward, so that the umbrella 20 can be inserted obliquely.

  The main body 10 is provided with an operation switch (not shown) and a stop switch (not shown) for operating / stopping the blower 8 described in detail later. The inside of the main body 10 is divided by a partition wall 10b and includes a water removal chamber 14, a drainage chamber 16, and an air supply chamber 18.

  The water removal chamber 14 is a space for accommodating the umbrella 20 in a closed state inserted into the insertion hole 22 from the tip. Inside the water removal chamber 14, there is a stone pitting (stone bump holding part) 24 obliquely below the insertion hole 22. The stone bumper 24 accommodates the stone bump 20c of the umbrella 20 inserted from the insertion hole 22 and holds it rotatably.

  A notch (mounting portion) 10c is formed at the lower end of the main body-side recess 10a constituting the insertion hole 22. A hand 20b of the umbrella 20 inserted into the insertion hole 22 is rotatably mounted in the cut 10c. The notch 10c and the stone piling 24 have functions of supporting the umbrella 20 obliquely and positioning the umbrella 20 in the water removal chamber 14 at an optimum position for removing water droplets.

  Since the umbrella 20 is inserted obliquely, if the user releases the hand 20b after the stone protrusion 20c is held in the stone protrusion case 24, the hand 20b is naturally formed in the notch 10c formed at the lower end of the main body-side recess 10a. And is supported diagonally. Therefore, the umbrella 20 can be easily placed at a position suitable for removing water droplets without performing a special operation. In the first embodiment, the hand 20b is supported by the notch 10c, but the intermediate rod 20a may be supported by the notch 10c.

  A nozzle (air ejection portion) 28 is formed in the partition wall 10b between the water removal chamber 14 and the air supply chamber 18. The nozzle 28 forms an elliptical opening that allows the water removal chamber 14 and the air supply chamber 18 to communicate with each other. Air discharged from the blower 8 (detailed later) in the air supply chamber 18 is jetted into the water removal chamber 14 through the nozzle 28.

  FIG. 3 is a view for explaining the flow of air ejected from the nozzle 28. The nozzle 28 ejects the air discharged from the blower 8 from the stone protrusion 20c side of the umbrella 20 and generates an air flow (flow of arrow X) from the stone protrusion 20c toward the tip 20f. The air ejected from the nozzle 28 flows from the stone protrusion 20c side to the tip 20f side while blowing (removing) water droplets adhering to the front surface of the umbrella cloth 20e.

  In the main body 10, the inner side surface (air facing surface) (air guiding portion) 10 e of the top plate 10 d on the insertion hole 22 side functions as an air facing surface. The inner side surface 10e is a surface located downstream of the tip 20f of the umbrella 20 and in the vicinity of the main body side recess 10a. The inner side surface 10e opposes the air flow after blowing off water droplets attached to the front surface of the umbrella cloth 20e. The air that collided with the inner surface 10e diffuses radially along the inner surface 10e with the collision point as the center. A part of the diffused flow (flow indicated by the arrow Y) flows toward the central axis 20 g of the umbrella 20.

  As shown in FIG. 4, a wind direction changing plate 30 is erected on the inner side surface 10e. The wind direction changing plate 30 is formed in a size that covers the entire width of the water removal chamber 14. A guide surface (air guide portion) 30a on the wind direction changing plate 30 on which the flow of the arrow Y collides extends from the inner surface 10e toward the inside of the umbrella 20. Accordingly, the air directed toward the central axis 20g of the umbrella 20 is changed in direction by the guide surface 30a of the wind direction changing plate 30 and guided to the inside of the umbrella 20 (flow of arrow Z). That is, the guide surface 30a cooperates with the inner surface 10e to guide the air flow from which water droplets attached to the umbrella cloth 20e are removed to the inside of the umbrella 20.

  In the first embodiment, the distance between the standing position of the wind direction changing plate 30 (intersection of the inner surface 10e and the guide surface 30a) and the central axis 20g of the umbrella 20 is 100 mm or less. Generally, there are many umbrellas whose distance from the central axis to the tip is 100 mm or more. Therefore, if the standing position of the wind direction changing plate 30 is between the center rod 20a and the center rod 20a from the center axis 20g, air can be guided to the inside of most of the umbrellas 20 regardless of the type of the umbrella 20. it can. Further, in the first embodiment, the guide surface 30a is substantially parallel to the central axis 20g, and coupled with the standing position of the wind direction changing plate 30, the air can be more reliably guided to the inside of the umbrella 20.

  The drain chamber 16 is a space for temporarily storing water droplets blown off by air. A drain tank 32 is disposed in the drain chamber 16. A drainage port 10f is formed in the partition wall 10b between the water removal chamber 14 and the drainage chamber 16, and the partition wall 10b between the water removal chamber 14 and the drainage chamber 16 is inclined toward the drainage port 10f. . Water droplets blown off from the umbrella cloth 20e by the air ejected from the nozzle 28 fall onto the partition wall 10b and flow down toward the drain port 10f. Water droplets flowing down toward the drain port 10f fall from the drain port 10f toward the drain tank 32. When water accumulates in the drainage tank 32, the drainage tank 32 can be taken out and the accumulated water can be discarded. In the first embodiment, the water droplets blown off from the umbrella cloth 20e are once accumulated in the drainage tank 32. However, a pipe may be connected to the drainage chamber 16 so that the drainage can be performed without accumulating the waterdrops. This is convenient because it is not necessary to bother the water accumulated in the drainage tank 32.

  FIG. 5 is a cross-sectional view taken along line AA in FIG. The air supply chamber 18 is a space for taking in air and ejecting the taken-in air from the nozzle 28. The air supply chamber 18 includes a suction air passage 34 and a blower housing chamber 36. The suction air passage 34 and the blower housing chamber 36 are separated by a partition 18a.

  An air intake port 38 is formed in the suction air passage 34. A suction air passage 34 and the outside of the umbrella dewatering machine 2 are connected via an air intake port 38. When the blower 8 is in an operating state, the suction air passage 34 has a negative pressure due to the action of the blower 8, and outside air (air) is taken in from the air intake port 38. The air intake port 38 is covered with an air filter (dust collecting means) 40. The air filter 40 removes foreign matters such as dust from the air taken in from the air intake port 38, and prevents dirt inside the umbrella dewatering machine 2 and equipment failure. A sound absorbing material 43 is attached to the inside of the suction air passage 34. The sound absorbing material 43 prevents noise generated by the air passing through the suction air passage 34 from leaking to the outside.

  The blower accommodating chamber 36 accommodates the blower 8 and ejects air taken in from the air intake port 38 from the nozzle 28. A communication port 18b is formed in the partition 18a. The blower housing chamber 36 and the suction air passage 34 are connected via the communication port 18b.

  The blower 8 is sandwiched between the packing 44 and the vibration isolation member 46 and accommodated in the blower accommodating chamber 36. The suction port 42 of the blower 8 is connected to the communication port 18 b via a packing 44, and the opposite side of the suction port 42 is fixed to the inner wall of the blower housing chamber 36 via a vibration isolation member 46. Since the suction port 42 is connected to the communication port 18b via the packing 44, air leakage from the gap between the suction port 42 and the communication port 18b can be reduced. Further, since vibration due to the operation of the blower 8 is absorbed by the packing 44 and the vibration isolation member 46, it is possible to prevent vibration from being transmitted to the main body 10 and to suppress generation of noise.

  The blower 8 enters an operation state when the operation switch is pushed by the user. When the blower 8 is in an operating state, a fan (not shown) held inside the blower 8 rotates and air is sucked from the suction port 42. Air sucked from the suction port 42 is discharged into the blower housing chamber 36 from a discharge port (not shown) opened to the blower housing chamber 36. Since the opening area of the nozzle 28 is smaller than the amount of air discharged from the blower 8, the air is ejected vigorously from the nozzle 28.

  Next, the operation procedure of the umbrella water remover 2 will be described. A user of the umbrella dewatering machine 2 inserts the umbrella 20 in a closed state into the insertion hole 22 formed in the main body 10, and puts the stone protrusion 20c of the umbrella 20 in the stone protrusion case 24, and puts the hand 20b in the notch 10c. Put. The umbrella 20 in the dewatering chamber 14 is positioned and supported diagonally by the stone entry 24 and the notch 10c. When the user presses the operation switch, the blower 8 enters an operation state. When the blower 8 is in an operating state, air is sucked from the suction port 42 via the suction port 42 and the suction air passage 34. Air sucked from the suction port 42 is discharged from the discharge port to the blower housing chamber 36. The air discharged from the discharge port is jetted into the water removal chamber 14 from the nozzle 28 formed in the partition wall 10b.

  The air ejected from the nozzle 28 to the water removal chamber 14 forms an air flow (flow indicated by an arrow X) from the stone bump 20c side of the umbrella 20 toward the tip 20f side. The air ejected from the nozzle 28 blows off water droplets adhering to the front surface of the umbrella cloth 20e in the process from the stone protrusion 20c of the umbrella 20 to the tip 20f.

  In the process from the stone bump 20c of the umbrella 20 to the tip 20f, the air that has blown off (removed) water droplets adhering to the front surface of the umbrella cloth 20e collides with the inner surface 10e of the main body 10 downstream of the tip 20f. And diffused. Of the air that has collided with the inner surface 10e and diffused, the air (flow in the arrow Y) toward the central axis 20g of the umbrella 20 collides with the guide surface 30a of the wind direction changing plate 30 and is guided to the inside of the umbrella 20 (arrow). Z flow). The air guided to the inside of the umbrella 20 spreads the slack of the umbrella cloth 20e. As the sagging of the umbrella cloth 20e spreads, the overlap is also eliminated. Therefore, in the process in which the air ejected from the nozzle 28 reaches the tip 20f from the stone protrusion 20c of the umbrella 20, it becomes easy to hit the umbrella cloth 20e evenly, and the water droplet removal performance is improved.

  By rotating the hand 20b of the umbrella 20 protruding from the insertion hole 22 to the outside of the box body 4, water droplets attached to the entire umbrella cloth 20e can be blown off with air. Since the umbrella 20 is positioned and supported by the notch 10c and the stone piling 24, even if the umbrella 20 is rotated, the direction of the central axis 20g of the umbrella 20 hardly changes and a good water removal performance can be maintained. . When the removal of water droplets is completed, the blower 8 is stopped by pressing a stop switch. Then, the lid 12 is opened and the umbrella 20 is taken out. By opening the lid 12, the umbrella 20 is taken out from the take-out opening 11 that is opened larger than the spread of the tip 20f. Therefore, when the umbrella 20 is taken out, the tip 20f is not easily caught and the umbrella 20 can be easily taken out. it can. (See also Fig. 6)

  In addition, when air collides with the inner surface 10e or when the flow direction is changed by the guide surface 30a, the water droplets removed from the umbrella cloth 20e are separated from the air, so that the air is directed toward the inside of the umbrella 20. Contains almost no water droplets.

  Further, the wind speed and flow direction of the air guided to the inside of the umbrella 20 change in time series depending on the state of the umbrella cloth 20e and the like. The umbrella cloth 20e vibrates (flickers) due to the time-series change of the air guided to the inside of the umbrella 20. Since the water drops from the front surface of the umbrella cloth 20e due to this vibration, the removal performance can be further improved.

  According to the above configuration, it is necessary to provide separate nozzles and air passages in order to generate an air flow for removing water droplets from the front surface of the umbrella cloth 20e and an air flow for expanding the sagging of the umbrella cloth 20e. Therefore, the structure can be simplified and the cost can be reduced. Further, since the air after removing the water droplets on the umbrella cloth 20e is used as it is for eliminating overlapping of the slack of the umbrella cloth 20e, the necessary air volume is reduced, and power saving and noise reduction can be achieved.

  In the first embodiment, the wind direction changing plate 30 is formed with a size that covers the entire width of the water removal chamber 14, but it may be formed smaller than this. For example, as shown in FIG. 7, even when the wind direction changing plate 30 is formed small, the air flow (flow of arrow Y) that collides with the inner surface 10e and moves toward the middle rod 20e of the umbrella 20 is guided to the inside of the umbrella 20. (Flow of arrow Z) is sufficient. The material cost can be reduced by forming the wind direction changing plate 30 small.

  In the first embodiment, the main body 10 is provided with the air guiding portion. However, the present invention is not limited to this, and the air guiding portion may be provided downstream of the tip 20f as a separate member.
