Description

  The present invention relates to an electric mixer in which a bottle is detachable and shreds and / or agitates food.

  A conventional electric mixer will be described with reference to the drawings. 6 is a cross-sectional view of a conventional mixer, and FIG. 7 is a cross-sectional view of the electric mixer shown in FIG. 6 with the bottle removed. As shown in FIG. 6, the electric mixer includes an electric motor 901 and a main body 90 provided with a start switch 902 for starting operation of the electric motor 901, and a container 91 detachably mounted on the upper portion of the main body 90. ing. The container 91 includes a cutter base 911 disposed in the lower part and a bottle 912 that is formed in a cylindrical shape and is screwed onto the upper part of the cutter base 911. A packing 913 is sandwiched between the cutter base 911 and the bottle 912, and the container 91 is ensured to be watertight.

  The cutter base 911 is provided with a cutter 914 for chopping and stirring the material charged in the container 91 at the top. The cutter 914 is connected to the electric motor 901 through a coupling. The power of the electric motor 901 is transmitted through the coupling, and the cutter 914 is rotated.

  When the starter switch 902 is pressed while the container 91 is placed on the main body 90, the electric mixer drives the electric motor 901 to rotate the cutter 914, and the material placed inside the container 91 is reduced. It stirs and stirs. The electric mixer includes a detection device 92 for preventing the electric motor 901 from operating when the container 91 is not placed on the main body 90.

  The detection device 92 includes a detection rod 921 slidably disposed on a mounting portion 915 disposed on the inside of the cutter base 91. The detection rod 921 has a flange in the middle. A coil spring 922 that is in contact with the flange and pushes the detection bar 921 upward is fitted on the lower side of the flange of the detection bar 921. The detection rod 921 is pushed upward by a coil spring 922, and the upper end portion protrudes from a through hole formed in the cutter base 91. Further, when the detection rod 921 slides downward, the lower end portion protrudes downward from the lower portion of the attachment portion 915.

  Note that the through hole is formed outside the region surrounded by the packing 913 in order to prevent moisture from flowing out between the through hole formed in the upper surface portion of the cutter base 911 and the detection rod 921. When the bottle 912 is screwed into the cutter base 911, the detection rod 921 is pushed by the lower surface portion of the bottle 912 and slides downward.

  Further, the detection device 92 is formed on the upper surface portion of the main body 90 and is connected and fixed to a lower portion of a mounting portion 903 having a through hole, and a box-shaped switch housing portion formed on the lower portion of the cylindrical portion 923. 924, a shaft 925 slidably housed inside a cylindrical portion 923, and a detection switch 926 attached and fixed to the switch housing portion 924. The shaft 925 has a large-diameter portion at the center, and a coil spring 927 is externally fitted to a portion below the large-diameter portion of the shaft 925.

  The shaft 925 is pushed upward by a coil spring 927, and the upper end portion protrudes from the upper surface portion of the main body 90 from the through hole of the attachment portion 903. When the upper end portion of the shaft 925 is pushed, the shaft 925 slides inside the cylindrical portion 923, and the lower end portion protrudes inside the switch storage portion 924. A lower end portion of the shaft 925 and a push button 928 formed on the detection switch 926 are arranged to face each other.

  Further, the main body 90 includes a plurality of convex portions (not shown) on the upper surface portion, and the convex portion engages with an engagement hole (not shown) formed on the lower surface portion of the cutter base 914. By mounting 91 on the main body 90, the detection rod 921 and the shaft 925 are arranged on the same axis in the vertical direction.

  In a state where the bottle 912 is attached to the cutter base 911, the detection rod 921 is pushed by the lower surface of the bottle 912, and the lower end portion of the detection rod 921 protrudes below the attachment portion 915. When the container 91 is set on the main body 90 with the detection rod 921 protruding downward, the lower end portion of the detection rod 921 pushes the upper end portion of the shaft 925 downward. The shaft 925 pushed at the upper end slides downward, and the lower end pushes the push button 928 of the detection switch 926.

  In the electric mixer, when the start switch 902 is operated in a state where the push button 928 of the detection switch 926 is pressed, the electric motor 901 is driven, and the cutter 914 rotates through the coupling.

  In the electric mixer, when the bottle 912 is screwed into the cutter table 911, foreign matter is caught between the detection rod 921 and the lower surface of the bottle 912, or the packing 913 is forgotten to be attached. The detection rod 921 may be pushed deeper than when the bottle 912 is attached to the bottle. When the detection rod 921 is pushed deeper than usual, the length of the portion where the lower end portion of the detection rod 921 protrudes from the lower portion of the attachment portion 915 also increases.

  When the container 91 is attached to the main body 90 in a state where the length of the portion protruding from the lower portion of the attachment portion 915 of the detection rod 921 is long, the amount of movement by the shaft 925 being pressed increases, and the push button of the detection switch 926 increases. 928 may be pushed excessively. If the push button 928 is pushed excessively, the detection switch 926 itself may be damaged or cause a failure, or the attachment portion between the detection switch 926 and the switch storage portion 924 may be damaged.

  Therefore, as shown in FIG. 8, there has been proposed a structure in which the shaft 93 is divided into upper and lower parts and a spring 933 is disposed between the upper shaft 931 and the lower shaft 932. According to this configuration, even if the detection rod 921 is pushed deeper than usual as described above, the force from the shaft 931 is not reached until the lower end of the upper shaft 931 comes into contact with the upper end of the lower shaft 932. Is transmitted to the lower shaft 932 via the spring 933. At this time, the amount of movement of the upper shaft 931 is absorbed to some extent by the deformation of the spring 933, the amount of pushing of the push button 928 becomes an appropriate length, and a malfunction such as failure or breakage of the detection switch 926 or the switch housing portion 924 is suppressed. be able to.

  Further, as shown in FIG. 9, the shaft 94 is divided into upper and lower parts, and the lower end portion of the upper shaft 941 is formed so as to be inserted into the recessed hole formed in the lower shaft 942, and the upper shaft 941 A structure in which a spring 943 is disposed between the lower shaft 942 and the lower shaft 942 has been proposed. According to this configuration, even when the detection rod 921 is pushed deeper than usual as described above, the lower end portion of the upper shaft 941 slides inside the recessed hole of the lower shaft 942. Further, since the force from the shaft 941 is transmitted to the lower shaft 942 via the spring 943, the amount of movement of the upper shaft 941 is absorbed to some extent, and the amount by which the push button 928 is pressed becomes an appropriate length. Problems such as failure and breakage of the switch 926 and the switch housing portion 924 can be suppressed.

Further, in the invention described in Japanese Patent Laid-Open No. 2003-70658, a notch is formed in a part of the female screw portion, and a slidable relay part is disposed in the notch. The relay part is placed on the male screw of the bottle and moves downward. In this state, the container is placed on the container and the interlock is released.
JP 2003-70658 A

  However, in the case of the mixer shown in FIGS. 8 and 9, the shaft is divided into two parts to absorb the excessive movement of the upper shaft between the two shafts and transmit the force from the upper shaft to the lower shaft. The structure is provided with a spring for the purpose, and the structure is complicated.

  Further, in the invention described in Japanese Patent Laid-Open No. 2003-70658, the interlock release method is omitted, but there is no description of how to deal with excessive pressing, and relay parts are excessively pressed. In such a case, the mechanism for releasing the interlock may be damaged.

  Then, this invention is provided with the detection apparatus which detects that the container is attached, and it aims at providing the electric mixer which can operate the said detection apparatus irrespective of the attachment state of the said container. .

  In order to achieve the above object, the present invention includes a main body in which an electric motor is incorporated, a cutter base that is detachably mounted on an upper portion of the main body, and an internal thread is provided on an inner peripheral surface, and an outer thread is provided on an outer peripheral surface. A container that is assembled by being screwed with the formed bottle; and a detection device that detects that the container is placed on the upper portion of the main body, and the detection device is vertically installed inside the cutter table.

A shaft that is pushed downward at the lower end of the detection rod when the container is attached to the main body, and a detection switch disposed at a lower portion of the shaft inside the main body. The detection switch is A push button that is pushed in a direction that intersects the sliding direction of the shaft; and the push button that is supported by the casing of the detection switch and is rotated until it comes into contact with the side periphery of the shaft. It has a lever part to push.

  According to this configuration, since the shaft member pushes the push button through the lever even when the sliding amount is larger than when the shaft member is pushed excessively and the container is normally attached, the push button is pushed. It is possible to suppress the button from being pushed more than necessary. Thereby, it can suppress that a detection switch fails or is damaged.

  In the above configuration, the lever is connected to a hinge portion, which is the center of rotation, on the upper portion, and the lever is rotatably supported above the push button outside the casing of the detection switch via the hinge portion. May be.

According to the present invention, it is possible to provide an electric mixer that includes a detection device that detects that a container is attached and can operate the detection device regardless of the attachment state of the container.

  The best embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a cross-sectional view of an electric mixer according to the present invention. The electric mixer A includes a main body 1 provided with an electric motor 10 and a start switch 11 for starting the operation of the electric motor 10, and a container 2 detachably mounted on an upper surface portion of the main body 1.

  The container 2 includes a cutter base 21 disposed at the lower portion and having an internal thread formed on an inner peripheral surface thereof, and a cylindrical bottle 22 having a male thread threadedly engaged with the internal thread of the cutter base 21. The cutter base 21 is often made of resin, and the bottle 22 is often made of glass. A packing 23 is sandwiched between the cutter base 21 and the bottle 22, and the container 2 ensures water tightness with the packing 23. The cutter base 21 is provided with a cutter 24 at the top for chopping and stirring the material charged into the container 2.

  In the electric mixer A, the electric motor 10 and the cutter 24 are connected via the coupling 25 by placing the container 2 on the upper surface of the main body 1. Then, the rotation of the electric motor 10 is transmitted to the cutter 24 through the coupling 25, and the cutter 24 rotates, whereby the material put into the container is shredded and stirred.

  The electric mixer A is provided with a detection device 3 that detects that the container 2 is correctly placed at the mounting position of the upper surface portion of the main body 1. The detecting device 3 is attached to the inside of the cutter base 21 so as to be detachable, a detecting rod 32 slidably arranged inside the attaching portion 31, and a detecting rod 32 attached to the detecting rod 32. And a coil spring 33, which is an elastic member that pushes.

  The detection rod 32 is a columnar member, and a flange 320 having a larger outer diameter than other portions is formed at an intermediate portion. A coil spring 33 is externally fitted below the flange 320 of the detection rod 32, and the upper portion of the coil spring 33 is in contact with the flange 320 and the lower portion thereof is in contact with the attachment portion 31. The detection bar 32 is pushed upward by the elastic force of the coil spring 33, and the upper end 321 protrudes upward from the through hole 211 formed in the upper surface of the cutter base 21. At this time, the flange 320 is in contact with the edge of the through hole 211, and the detection rod 32 suppresses the removal from the through hole 211. Further, the detection rod 32 slides downward by being pushed downward, and the lower end portion 322 projects downward from the lower portion of the attachment portion 31.

  In addition, the detection device 3 is mounted and fixed on the inner side of the cylindrical fixing portion 12 formed on the upper surface portion of the main body 1, and is slidably disposed inside the cylindrical portion 34. A shaft 35 and a coil spring 36, which is an elastic member that pushes the shaft 35 upward, are provided. The cylindrical portion 34 includes a bottom surface portion 341 at a lower end portion, and a through hole 342 is formed in the bottom surface portion 341. The shaft 35 has a large-diameter portion 350 formed in the middle portion. A coil spring 37 is externally fitted below the large diameter portion 350 of the shaft 35. The upper end portion of the coil spring 37 is in contact with the lower end portion of the large-diameter portion 350, and the lower end portion is in contact with the bottom surface portion 341 of the cylindrical portion 34, and the shaft 35 is pushed upward by elastic force. Accordingly, the upper end portion 351 of the shaft 35 protrudes from the upper end portion of the cylindrical portion 34 and is disposed inside the fixed portion 12. Further, the shaft 35 slides downward by being pushed downward, and the lower end portion 352 of the shaft 35 protrudes downward from the through hole 342 of the cylindrical portion 34.

  Further, the detection device 3 includes a rectangular parallelepiped switch storage portion 37 formed at the lower end portion of the cylindrical portion 34 and a detection switch 38 that is stored and fixed in the switch storage portion 37. The switch housing portion 37 is formed in contact with the bottom surface portion 341 of the cylindrical portion 34, and the lower end portion 352 of the shaft 35 enters the inside of the switch housing portion 37 from the through hole 342.

  The detection switch 38 is a switch for detecting that the container 2 is placed at an appropriate position on the upper surface of the main body 1. The detection switch 38 is attached so that the push button 381 forms a predetermined angle (here, vertical) with respect to the sliding direction of the shaft 35. The detection switch 38 is a switch device that is actuated when the push button 381 is pressed by a certain amount.

  Further, the detection switch 38 has a long flat plate-like lever portion 382 and a hinge portion 383 integrally formed at one end in the longitudinal direction of the lever portion 382 and supported on the side surface portion of the casing of the detection switch 38. Is provided. The lever portion 382 and the hinge portion 383 are not limited thereto, but here are formed by cutting and bending a metal plate. In addition, the hinge portion 383 is not limited thereto, but here is pivotally supported on the side surface portion of the casing of the detection switch 38.

  A hinge portion 383 is formed above the push button 381 of the casing of the detection switch 38. Since the hinge portion 383 is formed on the upper side surface portion of the casing of the detection switch 38, the lever portion 382 integrally formed with the hinge portion 383 rotates downward due to its own weight, and remains stationary while being in contact with the push button 381. is doing. The lever portion 382 is disposed so as to push the push button 381 by being rotated toward the detection switch 38 around the hinge portion 83.

  In the detection device 3, when the shaft 35 slides downward, the lower end portion 352 of the shaft 35 protrudes from the through hole 342, and the lower end portion 352 contacts the lever portion 382. As the shaft 35 moves further downward, the lever portion 382 is rotated in the direction of the push button 381 by being pushed by the lower end portion 352. When the lower end portion 352 moves below the tip end portion of the lever portion 382, the lever portion 382 is rotated to a position where it comes into contact with the lower side peripheral portion of the shaft 35.

  By rotating until the lever portion 382 comes into contact with the lower peripheral portion of the shaft 35, the lever portion 382 pushes the push button 381 to an amount necessary for the operation of the detection switch 38, and the detection switch 38 is turned on. It becomes the state of. Further, while the shaft 35 is pressed and the lever portion 382 is in contact with the side peripheral portion of the lower portion of the shaft 35, the state where the push button 381 is pressed is maintained, and the detection switch 38 is kept on.

  Next, the operation of the detection device when the container 2 is placed on the main body 1 will be described. First, the container 22 is assembled by screwing the bottle 22 into the cutter base 21. When the bottle 22 is screwed, the bottom surface portion 221 of the bottle 22 comes into contact with the upper end portion 321 of the detection rod 32, and the detection rod 32 is pushed downward. Thereby, the lower end portion 322 of the detection rod 32 protrudes from the lower portion of the attachment portion 31.

  With the lower end portion 322 of the detection rod 32 protruding below the attachment portion 31, the container 2 is placed while being positioned at the attachment position of the upper surface portion of the main body 1. As a positioning method of the main body 1 and the container 2, for example, a protrusion is formed on the upper surface portion of the main body 1, and an engagement hole formed in the bottom surface portion of the container 2 (that is, the bottom surface portion of the cutter table 21). The thing made by inserting a protruding line can be mentioned.

  Since the container 2 is accurately positioned and placed at the mounting position on the upper surface portion of the main body 1, the electric motor 10 of the main body 1 and the cutter 214 of the container 2 are connected via the coupling 25. Further, when the container 2 is positioned with respect to the main body 1, the detection rod 32 attached to the cutter base 21 and the shaft 35 attached to the main body 1 are aligned vertically on the same axis. That is, the upper end 351 of the shaft 35 is pushed by the lower end 322 of the detection rod 32 by placing the container 2 at the attachment position on the upper surface of the main body 1.

  The shaft 35 is pushed by the detection rod 32 and slides downward, and the lower end portion 352 of the shaft 35 pushes the lever portion 382. The lever portion 382 is pushed by the lower end portion 352 and rotated around the hinge portion 383 toward the push button 381. When the lower end portion 352 of the shaft 35 moves below the lever portion 382, the lever portion 382 is rotated until it comes into contact with the lower side peripheral portion of the shaft 35, and the push button 381 is pushed by the lever portion 382. As a result, the detection switch 38 is turned on. While the container 2 is placed on the main body 1, the lever portion 382 continues to be in contact with the side peripheral portion of the lower portion of the shaft 35, and the push button 381 is continuously pushed, so that the detection switch 38 is ON. Maintained.

  By operating the start switch 11 provided in the main body 1 with the detection switch 38 turned ON, the electric motor 10 is driven, and the rotation of the electric motor 10 is transmitted to the cutter 24 via the coupling 25. Then, the cutter 24 shreds and stirs the material put into the container 2.

  Then, after the shredding and stirring are finished, the detection rod 32 is also separated from the shaft 35 by removing the container 2 from the main body 1. The shaft 35 pushed downward by the detection rod 32 is lifted upward by the elastic force of the coil spring 37. And the force which pushes the push button 381 of the lever part 382 is removed because the lower end part 352 of the shaft 35 moves upwards rather than the lever part 382. FIG. Thereby, the push button 381 returns to the original position while pushing the lever portion 382, and the detection switch 38 is turned off.

  Next, the electric mixer in a state where only the cutter base 21 is placed on the main body 1 will be described. FIG. 2 is a sectional view showing a state in which only the cutter base is attached to the main body. When cleaning the container 2, after the cutter table 21 and the bottle 22 are disassembled and cleaned, only the cutter table 21 may be placed on the main body 1. When the bottle 22 is not screwed onto the upper part of the cutter table 21, the detection rod 32 is pushed upward by the elastic force of the coil spring 33. When the cutter base 21 to which the bottle 22 is not attached is placed on the main body 1, the detection bar 32 is pushed upward, and the lower end 322 of the detection bar 32 does not press the upper end 351 of the shaft 35. The shaft 35 is also pushed upward by the elastic force of the coil spring 37.

  Since the shaft 35 does not move downward, the lever portion 382 is not pushed away, the push button 381 is not pushed, and the detection switch 38 is in an OFF state. Even if the start switch 11 is operated in this state (a state where only the cutter base 21 is attached to the main body 1), since the detection switch 38 is OFF, the electric motor 10 is not driven, and thus the cutter 24 rotates in an exposed state. Can be suppressed. Thus, in the electric mixer A, even if the start switch 11 is mistakenly operated, the cutter 24 exposed to the outside does not rotate, which is safe.

  Next, the operation of the electric mixer A when the packing 23 is forgotten to be attached will be described. FIG. 3 is a cross-sectional view of the electric mixer A when a container for which packing has been forgotten is attached to the main body. As shown in FIG. 3, when the cutter base 21 and the bottle 22 are screwed together without attaching the packing 23, the bottom surface portion 221 of the bottle 22 is more than the upper surface of the cutter base 21 compared to when the packing 23 is attached. Approaching the department. Thereby, the detection rod 32 is pushed deeper than in the case where the packing 23 is provided.

  When the lower end portion 352 of the shaft 35 moves downward from the tip end portion of the lever portion 382, the lever portion 382 is further rotated and comes into contact with the lower peripheral portion of the shaft 35. At this time, the push button 381 is pushed by the lever portion 382, and the detection switch 38 is turned ON. Since the detection rod 32 is pushed deeply, the shaft 35 pushed by the lower end 322 of the detection rod 32 when the container 2 is placed on the main body 1 is also pushed deeper than when the packing 23 is attached. It is. When the shaft 35 is pushed further deeper, the side peripheral portion of the lower portion of the shaft 35 only slides with respect to the lever portion 382, and the lever portion 382 is not further rotated.

  Therefore, even if the shaft 35 is pushed deeper than when the packing 23 is attached, the lever portion 382 does not further rotate, so that an excessive force does not act on the detection switch 38. Thereby, even when the packing 2 is forgotten to be assembled and the container 2 is assembled, the push button 381 is excessively pushed and broken or damaged, or the fixing portion between the detection switch 38 and the switch storage portion 36 is fixed. It is possible to suppress the occurrence of a problem that an excessive force acts on and breaks.

  The bottle and the detection rod will be described. The bottle 22 is formed of glass as described above, and is often formed by cutting and polishing the glass. When formed by polishing glass, fine irregularities remain on the surface of the bottom surface portion 221 of the bottle 22. The bottle 22 is screwed to the cutter base 21, and the upper end 321 of the detection rod 32 relatively circulates inside the bottom surface 221 while being in contact with the bottom surface 221 of the bottle 22. At this time, the bottom surface portion 221 of the bottle 22 is scraped off from the detection rod 32 every time the bottle 22 is attached to and detached from the cutter table 21 due to fine irregularities on the surface. If the detection rod 32 continues to be scraped, the length of the detection rod 32 will eventually become insufficient, the amount of protrusion of the lower end 322 of the detection rod 32 when the bottle 22 is attached will decrease, and the movement of the shaft 35 will be reduced. The amount becomes smaller. As a result, the lever portion 382 cannot sufficiently rotate, the push button 381 is not pushed, and the electric mixer A does not start.

  Therefore, a detection rod that can suppress the occurrence of the above-described problems will be described with reference to the drawings. FIG. 4 is an enlarged cross-sectional view of the detection rod, and FIG. 5 is an enlarged cross-sectional view of the detection rod with the bottle attached. As shown in FIGS. 4 and 5, a ball member 323 capable of rotating without axis may be attached to the upper end portion 321 of the detection rod 32. Since the ball member 323 is attached, when the bottle Bt is rotated to attach the bottle 22, the ball 323 is rotated in accordance with the rotation of the lower surface 221, so that the lower surface 221 of the bottle 22 and the detection rod 32 are Thus, it is possible to reduce the wear of the detecting rod 32.

  The above description of the embodiment is for explaining the present invention, and should not be construed as limiting the invention described in the claims or reducing the scope thereof. It is needless to say that each part configuration of the present invention is not limited to the above embodiment, and various modifications can be made within the technical scope described in the claims.

  Only when the container is securely attached, it can be applied to an electric mixer equipped with a detection device that operates.
