Description

  The present invention relates to a pulverization container and a pulverizer for hand mixers mainly used in general households.

The crushing container has a vertical dimension of the crushing chamber from the center of the blade to the tip so that it can be crushed to a fine particle size in a short time even if it is a relatively lightweight object such as tea leaves. There has been proposed a pulverizer having a size smaller than the size of the lid and bulging the center of the lid downward (for example, see Patent Document 1). In order to enhance the pulverization effect, a pulverization container provided with protrusions on the inner surface has been proposed (see, for example, Patent Document 2). Further, a blade provided with a hole in order to improve the pulverization performance has been proposed (see, for example, Patent Document 3).

  An object of the present invention is to make a fine powder in a short time even for a relatively lightweight object such as tea leaves. Furthermore, the pulverization container of the present invention usually has a pulverization chamber for normally pulverizing the material to be pulverized, but when pulverizing tea leaves or the like into a fine powder, the pulverization chamber is positioned at a low position using an inner lid. The crushing chamber is narrowed and used. Since the narrow crushing chamber may be about one third of the wide crushing chamber, the inner lid is arranged at a considerably lower position of the crushing chamber. In Patent Document 1, the pulverization chamber is narrowed using an inner lid, but the purpose of use is limited because the pulverization chamber cannot be widened, and the amount of the object to be pulverized is large and is not a fine powder. It is not suitable for crushing. SUMMARY OF THE INVENTION An object of the present invention is to provide a pulverization container in which normal pulverization and pulverization to make a fine powder can be performed using an inner lid, and the inner lid is easy to attach and takes less time.

Claim 1 of the present invention is a pulverization container used when pulverizing an object to be pulverized by rotating blades of a pulverizer of a hand mixer, and a hole through which a container body and a member for rotating the blades are inserted. equipped with a lid and a circular upper lid in having at least three projections formed on the inner surface of the side wall of the container body, the inner lid is supported horizontally at said at least three protrusions, the outer periphery and concentric to the upper cover A claw hole for inserting a claw portion provided in a protective cap attached to the tip of the hand mixer is formed in the upper lid, and the length of the claw hole in the radial direction of the upper lid is formed. Is at least half of the horizontal portion .

Claim 1 of the present invention comprises a container body, an inner lid having a hole through which a member for rotating the blades is inserted, and a circular upper lid, and at least three protrusions are formed on the inner surface of the side wall of the container body. The inner lid is horizontally supported by the at least three protrusions, and the upper lid is formed with a horizontal portion concentric with the outer periphery thereof, for inserting a claw portion provided in a protective cap attached to the tip of the hand mixer. Are provided in the upper lid, and at least half of the length of the claw hole in the radial direction of the upper lid penetrates the horizontal portion . Therefore, since the grinding chamber can be narrowed by attaching the inner lid, even a relatively lightweight object such as tea leaf can be made into a fine powder in a short time. Also, during normal pulverization that does not make a fine powder with a large amount of material to be pulverized, the inner lid can be removed to widen the pulverization chamber, and the inner lid can be easily attached and detached for convenient handling. . Further, a horizontal portion concentric with the outer periphery of the circular upper lid is formed, and a claw hole for inserting a claw portion provided in a protective cap attached to the tip of the hand mixer is provided in the upper lid. At least half of the length of the claw hole in the radial direction passes through the horizontal portion. Therefore, when the claw portion is inserted into the claw hole, the protective cap always comes into contact with the horizontal portion, so that the hand mixer is stabilized during use.

  Next, the best mode for carrying out the present invention will be described. As shown in FIG. 3, the main body 2 of the hand mixer 1 used in the present invention is formed in an elongated shape and has a built-in motor. An outer cylinder 3 extends from the tip of the main body 2, and a rotating shaft 4 that rotates by a motor projects from the outer cylinder 3 through the inside of the outer cylinder 3. The upper portion of the main body 2 is formed in a shape that is narrowed down from both side surfaces to the back surface, and that portion is a grip portion 5. Two switches 6 and 7 are provided on the front surface of the grip portion 5. The motor does not rotate when the switches 6 and 7 are not pressed. When the switch 6 is pressed, the rotary shaft 4 rotates at a low speed, and when the switch 7 is pressed, the rotary shaft rotates at a high speed. Although not shown, an electric cord extends from the upper end of the back surface of the main body 2 so that 100V AC electricity can be used.

  The outer cylindrical body 3 is formed of a pipe-shaped metal, and a circular umbrella-shaped protective cap 8 formed of metal is provided at an end of the outer cylindrical body 3. Three downward claw portions 9 are provided on the lower surface near the outer periphery of the protective cap 8. Since these claw portions 9 are all the same shape and provided at equal intervals, all the angles formed by the respective radial lines drawn from the center of the protective cap 8 to each claw portion are 120 degrees. The claw portion 9 may be fixed to the protective cap 8 by welding, may be another fixing method, or may be integrally formed.

  The crushing container 48 includes a container main body 10, an inner lid 11, and an upper lid 12. Moreover, as shown in FIG. 1, the container main body 10 has a double structure in which the outer member 13 and the inner member 14 are overlapped and coupled by a coupling device. The coupling device 15 will be described. Reference numeral 15 is an engaging projection provided on the bottom surface of the inner member 14 and there are two. The engagement protrusion 15 has a cylindrical shape, and a flange 16 is formed at the end. Reference numeral 17 denotes a recess formed in the bottom of the outer member 13, and there are two recesses corresponding to the engagement protrusion 15, and an engagement hole 18 is provided in these recesses. The engagement hole 18 has a shape in which an elongated hole portion that is slightly wider than the cylindrical portion of the engagement protrusion 15 and a round hole portion that can be inserted with the flange 16 communicate with each other, and is concentric with the container body 10. Slightly longer. When connecting the outer member 13 and the inner member 14, the flange 16 of the engaging protrusion 15 is inserted into the round hole portion of the engaging hole 18, and then the inner member 14 is rotated with respect to the outer member 13. The 15 cylindrical portions are moved to the elongated holes of the engagement holes 18. Thus, the outer member 13 and the inner member 14 are joined together because the flange 16 projects outward from the elongated hole portion.

  As shown in FIG. 4, a support shaft 19 is attached to the center of the inner member 14 of the container body. The support shaft 19 is for supporting the crushing device 47, but the support shaft 19 may not be present when the crushing device is fixed to the rotary shaft 4 of the hand mixer. A hexagonal engagement base 20 is integrally provided at the lower portion of the support shaft 19, and the engagement base 20 is engaged with a hexagonal engagement recess 21 provided at the lower end of the crusher 47 as shown in FIG. By combining, the crushing device 47 and the support shaft 19 rotate integrally, and the rotation of the crushing device 47 can be stabilized.

  The inner surface of the side wall of the inner member 14 is inclined so as to spread outward as it goes upward from the bottom, and four protrusions 22 are provided at equal intervals from the bottom of the inner surface of the side wall to a position slightly lower than the middle height. . The upper surface portions 23 of these protrusions 22 are formed in a planar shape, and a narrow mounting portion 24 that connects the upper surface portions 23 in a flush manner is formed. The inner lid 11 is supported by the upper surface portion 23 of the ridge, but the mounting portion 24 is for stably supporting the inner lid 11 and may not be present.

  FIG. 5 is a view of the inner lid 11 as viewed from below. As shown in the figure, a hole 25 is provided in the center, and a lower cylindrical portion 26 having an inner diameter larger than the inner diameter of the hole 25 is integrally provided around the hole 25. It has been. As shown in FIG. 1, the lower cylindrical portion 26 extends to the vicinity of the flat portions 42 and 43 near the center of the blade of the crushing device 47, and prevents the blade from floating during rotation. Three ridges 28 extend radially at an angle of 120 degrees from the lower cylindrical portion 26 to the vicinity of the outer periphery. The cross sections of the ridges 28 are triangular in order to prevent the ridges 28 from remaining on the upper surface portion 23 of the ridges of the inner member. Further, an upper cylindrical portion 27 having an inner diameter larger than the inner diameter of the hole 25 is integrally provided around the hole 25 on the upper surface of the inner lid 11. The upper cylindrical portion 27 abuts against the lower surface of the upper lid 12 as shown in FIG. 1 to prevent the inner lid 11 from floating during use. Further, the inner lid 11 can be attached and detached by grasping the upper cylindrical portion 27. The outer peripheral surface 29 of the inner lid is inclined so as to expand upward as in the case of the inner surface of the side wall of the inner member 14 described above, and is formed so as to be in close contact with each other.

  The inner lid 11 is used when making tea leaves into a fine powder form in a short time. The inner lid 11 is placed in the inner member 14 of the container body to define a narrow pulverization space, which is a pulverization chamber 30. At this time, the protrusion 28 does not rest on the upper surface portion 23 of the protrusion of the inner member, and the protrusion 28 is located between the protrusion 22 and the protrusion 22. Since the protrusions 28 extend radially at an angle of 120 degrees with respect to each other, and there are four upper surface portions 23 of the protrusions of the inner member at equal intervals, the inner lid 11 can be either Since the protrusion 28 always contacts the protrusion 22 of the inner member, further rotation can be prevented. In addition, when it is going to grind | pulverize with a wide grinding | pulverization chamber without using the inner lid | cover 11 for a narrow crushing chamber, the inner lid 11 is removed and the crushing container 48 is used.

  As shown in FIG. 6, the upper lid 12 has a hole 31 in the center and three claw holes 32 around the hole 31. Further, as shown in FIG. 1, a recess 33 is formed in the upper lid 12, and a horizontal portion 34 concentric with the upper lid 12 is formed in the vicinity of the periphery of the recess 33. It penetrates the horizontal part 34. With this configuration, since the bottom surface around the protective cap 8 is in full contact with the horizontal portion 34 during use, the hand mixer can be stabilized.

  7 to 9 show a crushing apparatus that can be used in the crushing container 48 of the present invention. As shown in FIG. 7, the crusher 47 has a configuration in which blades 36, 37, 38, 39 integrally formed of metal are attached in a cross shape near the lower end of the shaft portion 35. The blades 36 and 37 extending in the opposite direction on one of the cross-shaped straight lines descend obliquely leaving the flat portions 40 and 41 around the shaft portion 35 and extend horizontally again at the tip. Accordingly, these blades 36 and 37 rotate close to the bottom of the crushing chamber 30.

  In the blades 38 and 39 extending in the opposite direction on the other cross-shaped straight line, one blade 38 is formed longer than the other blade 39. The longer blade 38 rises obliquely leaving the flat portion 42 around the shaft portion, extends horizontally again, and rises obliquely again after that. And the hole 44 is drilled in the horizontal part in the middle. As a matter of course, the longer blade 38 is heavier than the short blade 39, so that if the rotation is performed without providing the hole 44, the rotation balance becomes worse and smooth rotation cannot be obtained. In view of this, the hole 44 is provided to eliminate the difference in weight and improve the rotation balance. In order to eliminate the difference in weight, it is not limited to providing a hole in the long blade 38. For example, a notch may be provided at the tip of the blade. Alternatively, a weight may be attached to the short blade 39.

  The shorter blade 39 rises obliquely leaving the flat portion 43 around the shaft portion, extends horizontally again, and further falls obliquely beyond that point. The reason for making the other blade 38 longer than this short blade 39 is that the crushing chamber 30 is formed wider as it goes upward, so that the tip of the long blade 38 positioned above the tip of the short blade 39 is used. This is because it is further extended and brought closer to the inner surface of the side wall of the crushing chamber 30 to improve the efficiency of crushing.

  The shaft portion 35 is formed of a cylindrical metal, and a notch 45 for connecting to the rotating shaft 4 is provided at the upper end. In addition, a truncated cone base 46 is provided on the lower end of the shaft portion 35 below the blade, and the above-described engagement recess 21 is provided on the inside thereof.

  Next, the usage method of the grinding | pulverization container 48 and the grinding | pulverization apparatus 47 is demonstrated. When using, first, the support shaft 19 of the container body is inserted from the lower end of the shaft portion 35 of the crushing device. Next, after putting the material to be crushed into the crushing chamber 30, the inner lid 11 is attached, and the upper lid 12 is further attached. The upper lid 12 is coupled by screwing or an alternative method so as not to be easily detached from the container body 10. Since the upper part of the shaft part 35 protrudes from the hole 31 of the upper lid, each claw part 9 is inserted into each claw hole 32 while the rotary shaft 4 of the hand mixer is inserted from the upper end of the shaft part 35. Now that pulverization is ready, one of the switches 6 and 7 is pressed to start the operation. When the switches 6 and 7 are turned off, the pulverization is completed. Therefore, the hand mixer 1 is removed, and the upper lid 12, the inner lid 11 and the pulverizer 47 are removed, and the object to be crushed is taken out.
