  1 to 6, the main body 11 has a motor (not shown) and a cup cradle 13 that receives the switch 12 and the cup 13a. A transparent glass container 14 for storing materials such as vegetables and fruits has a screw 15 formed at the lower part of the outer periphery and a cover 16 attached to the upper part. The container 14 is detachably attached to a container base 17 made of PP resin or the like via screws 15 and is detachably mounted on the main body 11 via the container base 17. The container base 17 is provided with an extraction pipe 18 for extracting the cooked food and a main bearing 19, and concave portions are formed on the outer and inner circumferences of the contact surface between the container base 17 and the main bearing 19 so that the food in the container 14 does not leak. 20 is formed, and an outer peripheral seal member 21 as a seal member is press-fitted to the outer periphery of the contact surface, and an inner peripheral seal member 22 is also press-fitted into the concave portion 20 with elastic rubber as the seal member on the inner periphery of the contact surface. Dimensioned and arranged. A container packing 23 is disposed between the container 14 and the main bearing 19.

  The main bearing 19 is made of phenol resin or the like having high heat resistance, and seals the main shaft 24, the cutter 25, the connector upper 26, an oilless bearing 27 that rotatably supports the main shaft 24, and food and oil. An oil seal 28, an opening 29 for extracting the food, and a filter fitting 30 formed in a lattice shape that prevents the coarse material from flowing out or clogging the extraction pipe 18, are in contact with the extraction pipe 18. The upper wall is made up. The main bearing 19 is attached to the container base 17 by a plurality of screws 31, and the cutter 25 is attached to a lower connector (not shown) and an upper connector 26 attached to a rotating shaft (not shown) of a motor in the main body 11. And are adapted to rotate.

  A cock 33 having an extraction port 32 and constituting a flow path of a cooked product such as juice is connected to the outlet of the extraction pipe 18 of the container base 17 via a fastening member 34 and a cock presser 35. When the cock retainer 35 having the screw 35 a formed on the inner periphery is screwed into the screw 36 formed on the container base 17 and fixed, a fastening member 34 that fits and contacts the cock retainer 35 is formed at the connection portion of the cock 33. The cock 33 is brought into contact with the flange 37 and pressed and fixed to the container base 17 via the O-ring 38, and the connecting portion is sealed. Further, the tightening member 34 is provided with a notch 39 so that it can be attached to and detached from the cock 33.

  In the flow path of the cock 33, a cock packing 40 made of rubber for sealing, and a cock stopper 41 to which the cock packing 40 is attached are disposed. The cock stopper 41 is slidably supported via the cock stopper holder 42, and is biased downward together with the cock packing 40 by a spring 43 and pressed against the inner wall of the cock 33. Further, a screw 42 a is formed on the inner periphery of the cock stopper holder 42 and is fixed by being screwed into a screw 44 of the cock 33 to block the opening above the extraction port 32.

  A stainless steel hook member 45 is insert-molded at the upper end of the cock stopper 41, and an opening 46 is formed in the hook member 45. The cock lever 47 is pivotally attached to the hook member 45 via the shaft portion 48 and is detachably attached through the opening portion 46, and the lower portion of the shaft portion 48 is hollowed out so as not to interfere with the cock stopper 41 that slides upward. By operating this, the cock stopper 41 is slid up and down.

  Further, on the lower part of the cock lever 47, flat portions are formed at the front and rear and the bottom, which are in contact with the upper surface of the cock stopper presser 42 and fix the cock lever 47 in the raised position or the collapsed position. The cock cover 49 is a member that covers the cock 33 and its periphery. A hole 50 through which the cock lever 47 is passed is formed, and is fitted and fixed to the container base 17.

  About the mixer comprised as mentioned above, the operation | movement and an effect | action are demonstrated below.

  With the cock lever 47 in the upright position, the juice material is put into the container 14, the switch 12 is turned on, and the cutter 25 is rotated through the transparent glass container 14 while checking the finished state of the juice for a predetermined time. Juice is completed. At this time, the oilless bearing 27 may become a high temperature exceeding 100 ° C. due to frictional heat with the main shaft 24 that rotates at high speed. The main bearing 19 that holds the oil-less bearing 27 is not transparent but has high heat resistance and is inexpensive. Because it is made of a suitable phenolic resin, thermal deformation does not occur.

  Further, when the oilless bearing 27 becomes high temperature, the lubricating oil impregnated inside oozes out to the surface, and the main shaft 24 and the upper connector 26 that rotate at high speed cause the oil to be brought into contact with the container base 17 and the main bearing 19 by centrifugal force. Although it is scattered on the inner periphery of the contact surface, since the portion is sealed by the inner peripheral seal member 22 over the entire periphery, the scattered oil does not enter the gap between the contact surfaces of the container base 17 and the main bearing 19. . Furthermore, since the joint portion of each part facing the juice is securely sealed by the container packing 23, the oil seal 28, the O-ring 38, and the cock packing 40, the juice does not leak even if it vibrates during operation.

  Next, juice is extracted by placing the cup 13 a on the cup cradle 13 and tilting the cock lever 47, the shaft portion 48 moves upward, and the cock packing 40 together with the cock stopper 41 that presses the upper portion of the extraction port 32 with the spring 43. Is pulled upward, the seal at the top of the extraction port 32 is released, and the juice in the container 14 flows through the extraction pipe 18 and the cock 33 and is poured from the extraction port 32 into the cup 13a.

  At this time, the juice is passed through the filtration fitting 30, and the material that could not be finely pulverized is not extracted. Further, when the cup 13a is filled with juice and the cock lever 47 that has been tilted is returned to the upright state, the cock plug 41 and the cock packing 40 are pressed against the upper part of the extraction port 32 by the spring 43 and sealed as before extraction. Therefore, juice extraction stops.

  After use of the mixer, as shown in FIGS. 5 and 6, the cock cover 49 is pulled out and the cock retainer 35 is twisted to disengage the cock 33 from the container base 17, and the clamping member 34 is moved upward while expanding the notch 39. The cock retainer 35 can also be removed from the cock 33. Further, when the cock stopper 42 is twisted to be removed from the cock 33 and the lower part of the cock packing 40 is pushed upward with a finger against the urging force of the spring 43 to bring the opening 46 above the cock stopper 42, the cock lever 47 The shaft portion 48 can be removed from the opening portion 46 and can be easily disassembled without using a tool. When the screw 31 is removed, the main bearing 19 can be removed from the container base 17 and the upper part of the extraction pipe 18 can be opened. The assembly of the cock 33 can be easily performed without tools as in the case of disassembly in the reverse procedure.

  As described above, in the present embodiment, the container 14, the container base 17, the main bearing 19, and the cock 33 are divided, and the outer peripheral seal member 21 and the inner peripheral seal are provided between the container base 17 and the main bearing 19. By disposing the member 22, the container 14 is formed of transparent and scratch-resistant glass, the main bearing 19 that requires heat resistance is formed of an opaque but inexpensive phenol resin, and the container base 17 that does not require heat resistance is It is made of PP resin that is inexpensive and has good mass productivity, and the cock 33 can be removed, disassembled and cleaned without tools, so each part is made of the optimal material, ensuring high durability and ease of use. Can be mass-produced at low cost.

  In addition, since the space between the container base 17 and the main bearing 19 is sealed, it is possible to prevent intrusion of juice, dirty water, oil, etc., and to prevent the gap from becoming dirty. Time and effort can be saved, and usability can be further improved.

  Further, when the juice extraction tube 18 is constituted by the container base 17 and the main bearing 19, and the divided portion is sealed by the outer peripheral sealing member 21, the screw 31 is loosened and the main bearing 19 is removed from the container base 17, Since the upper wall of the extraction tube 18 can be disassembled and opened, the inside of the extraction tube 18 can be easily and cleanly cleaned by putting a brush from above, and the careability can be improved. Further, at the time of assembly, since the outer peripheral seal member 21 is pressed around the entire periphery of the container base 17 and the main bearing 19 at the upper part of the extraction pipe 18 by tightening the screws 31, it is surely sealed and juice leakage or the container base 17 And dirt in the gap between the main bearing 19 can be prevented.

  Further, by arranging the outer peripheral seal member 21 and the inner peripheral seal member 22 on the outer periphery and inner periphery of the contact surface between the container base 17 and the main bearing 19, the clearance between the contact surface between the container base 17 and the main bearing 19 is reduced. Since both the inside and the outside are sealed, juice hangs down from the upper end of the container 14 and drops between the container 14 and the container base 17, or the main shaft 24 and connector through which the oil in the oilless bearing 27 rotates at high speed. The centrifugal force of the top 26 causes the container base 17 and the main bearing 19 to scatter on the inner periphery of the contact surface, soak the container base 17 that has been contaminated with juice after use in water for maintenance, or mix juice. Even if it is put in the sewage, it is possible to prevent juice, oil or sewage from entering the gap between the container base 17 and the main bearing 19, and to prevent the contact surface from becoming dirty.

  This gap is always generated because the flatness of the contact surface between the resin container base 17 and the main bearing 19 cannot be accurately obtained. In order to clean this, it is necessary to loosen the three screws 31 with a screwdriver and to remove the main bearing 19 from the container base 17. Therefore, by preventing this contamination, it is possible to reduce the maintenance and improve usability. .

  Furthermore, even if the container base 17 and the main bearing 19 are disassembled and turned upside down by forming a recess 20 in the container base 17 into which the outer peripheral seal member 21 and the inner peripheral seal member 22 are press-fitted and fitted, the outer peripheral seal member 21 The inner peripheral sealing member 22 does not fall off, and loss due to the dropping can be prevented. Further, since the outer peripheral seal member 21 and the inner peripheral seal member 22 are positioned by being press-fitted into the recess 20, when the container base 17 and the main bearing 19 are assembled, the outer periphery, the inner peripheral seal member 21, Therefore, it is possible to prevent the positional deviation and the erroneous mounting of the lens 22 from occurring and to prevent a seal failure. The recess 20 may be formed on the main bearing 19 instead of being provided on the container base 17, and the same effect can be obtained if the outer and inner peripheral seal members 21 and 22 are formed so as to have a press-fit dimension.

Further, the upper surface of the container base 61 is formed such that when the main bearing 19 is attached, there is a certain gap 62 between the main bearing 19 and the bottom surface of the main bearing 19, and the gap 62 is formed of elastic rubber or the like. A seal member 63 is provided. The seal member 63 is integrally formed in a sheet shape from the outer peripheral portion to the inner peripheral portion of the gap 62, and the outer peripheral portion 64 and the inner peripheral portion 65 of the seal member 63 are formed thicker than their intermediate portions. Yes.

  Further, the seal member 63 has three holes 66 through which the bosses 19a for tightening the screws 31 pass, a hole 67 formed at the center and through the connector 26, and a hole 68 formed above the extraction pipe 18 and through which juice passes. Is provided.

  About the mixer comprised as mentioned above, the operation | movement and an effect | action are demonstrated below.

  When the switch 12 is turned on and the cutter 25 is rotated, the lubricating oil oozed from the oilless bearing 27 by the main shaft 24 and the upper connector 26 rotating at high speed is centrifugally applied to the inner periphery of the contact surface between the container base 17 and the main bearing 19. However, since the portion is sealed by the sealing member 63 over the entire circumference, the scattered oil does not enter the gap between the contact surfaces of the container base 61 and the main bearing 19. In addition, juice hangs down from the upper end of the container 14 and drops between the container 14 and the container base 61, or the container base 61 dirty with the juice after use is immersed in water for cleaning. Even if it is put in sewage mixed with water, it is possible to prevent juice, oil or sewage from entering the gap between the container base 17 and the main bearing 19 and to prevent the contact surface from becoming dirty.

  As described above, in the present embodiment, the seal member 63 disposed on the outer periphery and the inner periphery is integrally formed, so that when the container base 61 and the main bearing 19 are disassembled and maintained, Only one of the peripheral seal members does not fall off, and the seal member 63 is large by integrating the outer periphery and the inner periphery, so that loss or forgetting to attach can be prevented. In addition, since the seal member 63 can be easily picked up by integration, the detachability is improved and the usability can be improved.

  Further, by forming the outer peripheral portion 64 and the inner peripheral portion 65 of the seal member 63 thicker than other intermediate portions, even if the flatness of the container base 61 and the main bearing 19 with which the seal member 63 abuts is somewhat worse, Even if the seal member 63 is slightly plastically deformed, the outer peripheral portion 64 and the inner peripheral portion 65 of the seal member 63 come into contact with the outer peripheral portion and the inner peripheral portion of the contact surface of the container base 61 and the main bearing 19, Since sealing can be surely performed at this location, it is possible to prevent juice, oil, and sewage from entering the gap between the container base 61 and the main bearing 19, and to improve the sealing performance and its reliability.

  As described above, the mixer according to the present invention can be reliably sealed between the container table and the main bearing, and thus can be applied to various devices and apparatuses having a sealing mechanism for sealing liquid or the like.
