Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a mixer, and more particularly, to a main body having a motor and a normally open safety switch for preventing driving of the motor, a rotary blade is supported, and the rotary blade is detachably mounted on the main body to mount the rotary blade. The present invention relates to a mixer including a container table that is connected to a motor and a container member that is detachably mounted on the container table and that constitutes a container in which a rotary blade is positioned.
[0002]
[Prior art]
Conventionally, a main body having a motor and a normally open safety switch for preventing driving of the motor and a rotary blade are supported, and are mounted on the main body so that the rotary blade can be attached and detached so that the rotary blade is connected to the motor. A container base and a container member that is detachably mounted on the container base and constitutes a container in which the rotary blade is located inside, and when both the container base and the container member are not mounted, the safety switch is normally opened. There is known a motor in which a motor cannot be driven by a motor (for example, see Patent Document 1).
[0003]
This is mounted so that two types of container members can be attached to and detached from the container base. It has two types of safety switches according to the type of container. The two containers differ in the height of the thread of the mounting portion to the container base, and have a difference in the amount of radially outward displacement of the first projection or boss provided on the container base when mounted on the container base. I have. Utilizing this difference, the second projection or boss that is interlocked with the pushed-out projection or boss by the deformation of the resin lever or the resin molding member is displaced to two different planar directions. The projections and bosses at the different displacement positions oppose the safety switch on the side corresponding to the type of the container member when the container base on which the container member is mounted is mounted on the main body, and push it. Thus, the motor can be driven continuously or intermittently according to the type of the mounted container member. This also avoids driving the motor without mounting the container stand or the container member. In particular, it is possible to prevent the danger of being driven by the motor with only the container base mounted and the rotary blade exposed.

[0005]
[Problems to be solved by the invention]
However, in the operation mechanism of the above-described conventional safety switch, a lever or a molded member having a complicated shape is used for the interlocking of the first and second projections and the boss in the above-described planar direction. The construction is complicated and expensive. Further, the required flat space is large, and the mixer is liable to be large-sized because it is provided on the outer periphery avoiding the annular seal portion between the container base and the container member.
[0006]
SUMMARY OF THE INVENTION An object of the present invention is to provide a mixer in which a safety switch can be operated with high durability by using a member which is provided simply and inexpensively with a small flat space around a seal portion between a container base and a container member.
[0007]
[Means for Solving the Problems]
In order to achieve the above object, the mixer of the present invention supports a main body having a motor and a normally open safety switch for preventing driving of the motor, a rotating blade, and can be detachably mounted on the main body. A container table which is mounted on the motor so that the rotary blade is connected to the motor; and a container member which is removably mounted on the container table and forms a container in which the rotary blade is positioned. A vertically movable member that moves up and down in response to the mounting and dismounting operation of the container member is provided on a portion of the container table that is provided around the annular seal between the members, and the container table is mounted on the main body, and One feature is that when the container member is mounted and the up-down moving member is in the down-moving position, the up-down moving member is directly or indirectly pressed by the safety switch of the main body to close and drive the motor. I have.
[0008]
In such a configuration, the rotating blade is connected to the motor by mounting the container base to the main body. However, this alone prevents the motor from being driven while the safety switch is normally open, so that the danger of being driven by the motor with the rotating blades exposed can be avoided. When the container member is mounted on the container table, a container having the rotary blade of the container table therein is formed, and the material contained therein can be processed by the rotary blade. At the same time, the vertically moving member of the container base is moved down in response to the mounting operation of the container member. By this downward movement, the up-down movement member causes the safety switch of the main body to be turned on in accordance with the downward movement if the container base is already mounted on the main body when the container base is subsequently mounted on the main body. It can be driven directly or indirectly to close, so the motor can only be driven when both the mounting of the container base to the main body and the mounting of the container member to the container base are in place. Use can be guaranteed.
[0009]
In particular, the vertical moving member only needs to be able to move up and down in response to the attachment and detachment of the container member to and from the container base. Cheap. Therefore, the size of the mixer is not increased, and further downsizing is easy. In addition, the vertical moving member is inexpensive and has high durability as long as it has a tension force when pushing the safety switch.
[0010]
The mixer of the present invention also includes a main body having a motor and a normally-open safety switch for preventing driving of the motor, a rotary blade, which is mounted on the main body so that the rotary blade can be detachably mounted on the main body. And a plurality of container members which are detachably mounted on the container table and constitute a container in which the rotary blade is located inside, and an annular seal portion between the container table and the container member. A vertically moving member that moves up and down in response to the mounting and dismounting operation of the container member is provided on a portion of the container base that is an outer periphery of the container base, and the container base is mounted on the main body, and the container member is mounted on the container base and the vertical movement is performed. Another feature is that when the moving member is in the lowering position, the up-and-down moving member directly or indirectly pushes the safety switch of the main body to close the main body so that the motor can be driven.
[0011]
In such a configuration, even when a plurality of container members are selectively mounted and used for one container base, the safety switch is closed by operating the vertical moving member of the container base, and the container base or the container is closed. If the member is not mounted, it is kept open, and proper use without danger or shortage of parts can be guaranteed.
[0012]
The vertically moving member moves up and down in a vertical notch provided on a surface of the container base on which the female spiral ridge is formed for mounting the container member, at a position radially outside the seal portion, and In response to the attachment and detachment of the further configuration,
Since the vertically moving member is located at the radially outer position of the seal between the container base and the container member, there is an advantage that the vertical movement member does not affect the seal part at all, and the female spiral ridge forming surface on which the container member of the container base is mounted. As it moves up and down in the vertical notch and works on the safety switch, the male spiral ridge of the container member does not affect the entry and exit along the female spiral ridge of the container base, It can be provided in the minimum required plane space of the conventional sealing structure and mounting structure.
[0013]
The vertically moving member is located on the path where the male spiral ridge for mounting on the container base of the container member enters along the female spiral ridge, and engages with the male spiral ridge that has entered to push down. In a further configuration, which has a projection that is responsive to the attachment and detachment of the container member by this engagement and disengagement,
The vertically moving member is located within the cutout of the female spiral ridge forming surface of the container base, and its own projection faces the entry path of the male spiral ridge of the container member from the formation surface, and the container member is mounted. When the male helical ridge enters along the female helical ridge, the male helical ridge engages with the male helical ridge and is pushed down, and thereafter is stabilized at the lower movement position, and conversely, the male helical ridge retreats. The push is released. In this way, the up-down moving member can move up and down in response to the attachment / detachment of the container member without interfering with the attachment / detachment operation of the container member with respect to the container base by the male and female spiral ridges. In the mounted state, even if the container member is removed from the container base, there is no fear that the vertically moving member independently projects outside and is caught by another.
[0014]
In a further configuration, the protrusion of the vertically moving member had a side shape of a shape and size not protruding from the cross-sectional profile of the female spiral ridge,
When the projection of the vertically moving member engages with the male helical ridge of the container member and is pushed down, thereafter, it stably stays at a position along the lower surface of the male helical ridge, and the longitudinal direction of the female helical ridge of the container base. Line up in the direction. At this time, since the side shape of the projection has a size and shape that does not protrude from the cross-sectional contour of the female spiral ridge, the male spiral ridge on the container member side pushes down the projection and does not interfere with the subsequent advance and retreat.
[0015]
Further objects and features of the present invention will become apparent from the following detailed description and drawings. The features of the present invention can be employed alone or in combination as variously as possible.
[0016]
【Example】
Hereinafter, embodiments of the mixer according to the present invention will be described with some examples with reference to FIGS. The embodiments described below are specific examples of the present invention, and do not limit the contents described in the claims. Further, the mixer may have a related function other than the mixer, for example, a mill function or a lowering function.
[0017]
In this embodiment, as shown in FIGS. 1 to 3, the example shown in FIG. 4, the example shown in FIG. 5, the example shown in FIGS. 6 to 8, and the example shown in FIG. The main body 11 having a normally open safety switch 27 for preventing the rotating blade 51 and the container table 12 which supports the rotating blade 51 and is detachably mounted on the main body 11 so that the rotating blade 51 is connected to the motor 4. And a container member 50 which is detachably mounted on the container base 12 and constitutes the container 1 in which the rotary blade 51 is located.
[0018]
In addition, a vertically moving member 29 that moves up and down in response to the attaching and detaching operation of the container member 50 is provided in a portion of the container table 12 that is around the annular seal portion 52 between the container table 12 and the container member 50. . When the container base 12 is mounted on the main body 1 and the container member 50 is mounted on the container base 12 and the vertical moving member 29 is at the lower position, the vertical moving member 29 directly operates the safety switch 27 of the main body 11. Alternatively, it is indirectly pushed and closed to bring the motor 4 into a state where it can be driven. Here, the vertically moving member 29 is urged by the spring 54 so as to always be in the upwardly moving position so as to respond to the attaching / detaching operation of the container member 50. In the illustrated example, the spring 54 is a coil spring, but is not limited to this.
[0019]
In such a container base 12, the rotary blade 51 is connected to the motor 4 by being mounted on the main body 11. However, only by this, the up-down moving member 29 is in the up-moving position shown in the left part of FIG. 1 by the bias of the spring 54, and the example shown in the right side of FIG. 1, the example of FIG. 4, the example of FIG. In the example of FIG. 6 and the example of FIG. 9, it is not in the state of being moved downward, but remains as described above. For this reason, the safety switch 27 is in a state in which the vertical movement member 29 of the container base 12 is not pushed and operated and the drive of the motor 4 is prevented while being normally opened. Therefore, the danger of being driven by the motor 4 with the rotary blade 51 exposed can be avoided.
[0020]
When the container member 50 is mounted on the container base 12 as shown in the examples of FIGS. 1 to 3, the example of FIG. 4, the example of FIG. 5, the example of FIG. 6, and the example of FIG. Is formed inside the container 1 so that the rotating blade 51 can work on the contained material to be processed. At the same time, the vertically moving member 29 of the container base 12 is moved down as described above in response to the mounting operation of the container member 50. Due to this downward movement, the vertically moving member 29 is attached to the container table 12 with the downward movement if the container table 12 is already mounted on the main body 11, and when the container table 12 is subsequently mounted on the main body 11, The safety switch 27 of the main body 11 is directly or indirectly pushed to close. Thus, the motor 4 can be driven only when the mounting of the container base 12 on the main body 11 and the mounting of the container member 50 on the container base 12 are completed, and proper use without danger or shortage of parts is guaranteed. be able to.
[0021]
Here, the vertically moving member 29 only needs to be able to move up and down in response to the attachment and detachment of the container member 50 to and from the container table 12. Therefore, it is simple and has a small plane space, and is provided without being bulky around the annular seal portion 52 between the container base 12 and the container member 50. Therefore, the size of the mixer is not increased, and further downsizing is easy. In addition, the up-and-down moving member 29 is inexpensive and highly durable as long as it has a tension force capable of pushing the safety switch 27.
[0022]
In each of the examples shown in FIGS. 1 to 3 and the example shown in FIG. 9, a plurality of container members 50 are used. Specifically, in the examples of FIGS. 1 to 3, a large cup 14 and a smaller cap 15 are used. When the cup 14 is mounted, the mixer blade 3 is used as the rotary blade 51 so that mixer processing using the container 1 having a sufficient volume can be performed. When the cap 15 is mounted, the grater plate 5 is used as the rotary blade 51 so that the lowering vessel 1 can be efficiently grated while preventing the material from escaping. In the example of FIG. 9, a large cap 37 and a smaller cap 39 are used. When the cap 37 is mounted, the mixer blade 3 is used to perform mixer processing using the container 1 having a sufficient volume. When the small cap 39 is attached, the former is used for the lowering operation and the latter is used for the milling operation using the lowering plate 5 or the mill blade 31. Even if the mixer blade 3 and the mill blade 31 coexist, they do not interfere with each other.
[0023]
However, the grater 5 cannot coexist with the mixer blade 3 or the mill blade 31. This means that the grated plate 5 receives the cut bulk material on it from below and performs the grate processing without falling, while the grated material is quickly stored in the storage space 6 below the grate plate 5 and repeatedly grated. This is because receiving and miniaturization are prevented, so that when they coexist with the mixer blade 3 and the mill blade 31 that stir while cutting and crushing the material, they interfere with each other. Therefore, the rotating blades 51 that interfere with each other are replaced and used.
[0024]
As described above, even when a plurality of types of container members 50 are used, the vertical moving member 29 can be moved up and down in response to the attachment / detachment, so that the mounting of the container member 50 to the container base 12 mounted on the main body 11 can be performed. Depending on the presence / absence, the safety switch 27 can be closed or normally opened to ensure safety and proper use.
[0025]
Here, in the example shown in FIGS. 1 to 3, the mixer mode in which the mixer blade 3 located in the container 1 is driven by the motor 4 to extract and mix the material in the container 1, and the grater plate 5 is driven by the motor 4 A mode is provided in which the material in the container 1 is ground and the grounding mode is set. Further, in the example shown in FIG. 9, in addition to the cases of the examples of FIGS. 1 to 3, a mill mode in which the mill blade 31 located in the container 1 is driven by the motor 4 to pulverize the material in the container 1 is provided.
[0026]
Here, the example shown in FIGS. 1 to 3 will be described in more detail. The grater 5 has grater teeth 5a higher than its thickness and is supported at a height that forms a storage space 6 for storing grater under the grater 5a. It is set lower than the number. As shown in FIGS. 1, 2 and 3, the mixer blade 3 and the grater 5 are supported on separate mixer tables 16 and 17 so that they can be rotated by the rotating shaft 2. 17 are detachably mounted on the container base 12 so as to be selectively used.
[0027]
Further, as shown in FIG. 1, a switching operation section 21 for switching the rotation of the motor 4 between rotation in the mixer mode and rotation in the unloading mode is provided under the container 1 in the form of a knob. The switching operation unit 21 switches between a position where the motor 4 shown in the figure is turned off by a rotation operation, a mixer mode rotation position, and a lowering rotation position. Even if the switching operation section 21 sets the mixer mode or the lowering mode, the motor 4 cannot be driven if the safety switch 27 is in the normally open state. Here, the switching operation unit 21 also serves as an operation unit of a power on / off switch different from the safety switch 27.
[0028]
As described above, in the mixer of the present embodiment, the mixer blade 3 or the grater 5 according to the mode to be used is selectively used in the fixed container 1 and rotated by the motor 4 below the container 1. For example, the mixer function and the lowering function can be used properly. In the mixer function, the mixer blade 3 rotates in the container 1 to cut and agitate the input material while cutting and stirring the material. The grater function is to grind and scrape loose materials, such as diced radish and ginseng, that have been put into the container 1 by rotating the grater 5 while receiving the grater from below. As it proceeds, it is dropped into the lower storage space 6 from the gap between the graters 5a, the piercing hole, the gap between the grater 5 and the container 1, and the like. A small number of incidental objects and handling parts are necessary for the proper use of such functions, so that it is cheap and easy to handle and use. In addition, the function to use both is a cooking machine that is frequently used and has a high utilization rate.
[0029]
In particular, in the present embodiment, the rotation speed in the lowering mode is set lower than the rotation speed in the mixer mode, so that the processing conditions and processing quality in the mixer function are not impaired, and the lower teeth 5a are higher than the plate thickness. The unique processing conditions suitable for the lowering function can be satisfied by cooperating with the lowering plate 5 having the above. In addition, by forming a storage space 6 for storing the grated material under the grated plate 5, it is possible to prevent the grated material from accumulating on the grated plate 5 and repeatedly slicing it, thereby preventing the grated material from being finely divided by the grinding process. Good quality grater can be obtained.
[0030]
The number of revolutions of the mixer is usually around 18,000 rpm. If this is applied to the grated mode, the device for the grated teeth 5a of the grated plate 5 does not work, and the grated material is too fine and not delicious. Therefore, it is preferable that the lowering speed be about 12,000 rpm to 15,000 rpm. This gives a grater of appropriate roughness and texture. The grater 5a is preferably increased in proportion to the rotation speed. With respect to the rotation range, it is preferable to cut and raise a substantially 90 ° angled tooth 5a to a height of about 5 mm in a metal grater 5 having a thickness of about 0.5 mm to 3 mm. More specifically, it is preferable that the cross-cut area is pushed open with a tool so as to form a circular hole as shown in FIG. Preferably, the diameter of the hole 5b is about 5 mm to 8 mm. When the hole 5b having a diameter of about 8 mm is formed, the height of the grater 5a is about 5 mm. This is thought to be due to the extension of the grater 5 when cutting and raising. However, it seems that such a thing changes with the material used, actual processing conditions, and the processing method. The number of revolutions in the down mode can be achieved by switching the drive of the motor 4 in the mixer mode to half-wave rectified drive, and can be easily reduced to about 60% of the number of revolutions in the mixer mode. it can. However, it is a matter of course that other electric or mechanical shift control may be performed.
[0031]
In addition, the mixer blade 3 is generally required to be located at the bottom of the container 1 in addition to the stirring function, so that the processing by the mixer blade 3 can be performed over the entire material. According to such a relationship, the grater 5 is provided at a position higher than the mixer blade 3 to form the storage space 6. However, in the example shown in FIG. 1, the mixer blade 3 is used in combination with a low blade and a high blade, but the mixer blade 3 at a lower position is essential for the above-described reason, and the mixer blade 3 at a higher position is not essential. .
[0032]
The storage space 6 is made smaller than the material storage space 7 on the grater 5. This makes the storage space 6 smaller than the material storage space 7, that is, the upper space, which is a reasonable size for supplying the input material to the processing by the grater 5, which is smaller than that. Thus, the whole can be reduced to a necessary minimum size with no useless space.
[0033]
Further, as shown by a solid line in FIG. 1, the mixer blade 3 is supported by a rotary shaft 2 provided via a bearing 22 on a mixer base 16 made of a synthetic resin dedicated to the mixer mode, and the lowering plate 5 is shown by an imaginary line. As shown in FIG. 1 and FIG. 2, a rotating shaft 2 provided on a grater 17 made of a synthetic resin exclusively for the grater mode has a bearing 23 interposed therebetween. Each of the rotating shafts 2 is made of metal, and connects the mixer blade 3 and the grater plate 5 by caulking or the like.
[0034]
The cup 14 and the cap 15 are made of glass, and are fitted with helicoids or screws in common to the container base 12 made of synthetic resin which is detachably mounted on the upper part of the main body 11. Attach so that it can be attached and detached. The mixer table 16 or the grater 17 is removably mounted on the container base 12 and mounted on the main body 11 to connect the mixer blade 3 or the grater plate 5 to the motor 4 by the connecting portions 18 and 19. Like that. The mixer table 16 mounted on the container table 12 constitutes the container 1 in the mixer mode with the cup 14 mounted on the container table 12, and the grater table 17 mounted on the container table 12 is a container table. The small container 1 in the lowering mode is constituted by the cap 15 mounted on the container 12. However, the cup 14 and the cap 15 may be made of a synthetic resin.
[0035]
The seal portion 52 between the mixer table 16 and the cup 14 and between the grater 17 and the cap 15 is provided with one annular seal packing 25. The seal packing 25 can be used exclusively for the mixer table 16 and the grater table 17, but the same thing can be shared. When the cup 14 or the cap 15 is mounted on the container base 12, the seal packing 25 obtains a state where the cup 14 or the cap 15 is sandwiched between the counter 14 and the mixer base 16 or the grater base 17 which are opposed to each other, so that a reliable seal can be achieved. . Further, since the cup 14 has an open upper end, a lid 24 made of a synthetic resin is fitted so as to be detachable and closed.
[0036]
According to the specific structure as described above, the sides of the mixer table 16 and the grater table 17 to be used are placed on the container table 12 placed on the upper part of the main body 11, and the placed mixer table 16 or the grater table is placed. 17, the cup 14 or the cap 15 corresponding to the mixer blade 3 or the grater plate between the cup 14 or the cap 15 and the mixer table 16 or the grater table 17 mounted on the container table 12 is provided. The integrated container 1 located at the bottom is constructed so that 5 is driven from the main body 11 side, and a mixer function state or a lowering function state is obtained. Therefore, after mounting the two members of the container table 12 and the mixer table 16 or the grater table 17, it is possible to easily select and use it simply by attaching one of the cups 14 or the caps 15. In addition, the integrated container 1 is handled alone with the material or the processed one contained therein, and is placed on the main body 11 by the container base 12 which is a part of the container 1 to be in a processed state, or removed and processed. You can carry things with you. The container table 12 can also function as a table for mounting the container 1 on a table or a worktop other than the main body 11 by using the stationary surface 12b of the skirt wall 12a or the like. Since the container 1 can be disassembled into three members as shown in the down state in FIG. 2, it is convenient for taking out and cleaning the workpiece.
[0037]
The vertically moving member 29 is located radially outside the seal packing 25, which is the seal portion 52, as shown in FIGS. 1 to 3, and is a cup 14 or a cap which is a container member 50 provided on the container base 12. In the common male and female spiral ridges 41a and 41b for attaching the female screw 15, the vertical movement is performed within the vertical cutout 61 provided on the formation surface 12c of the female spiral ridge 41a on the container base 12 side, and the cup 14 and the cap are moved. 15 in response to the attachment and detachment. Accordingly, there is an advantage that the vertically moving member 29 is located radially outside the seal packing 25 between the container base 12 and the cup 14 or the cap 15 and does not affect the seal portion 52 formed by the seal packing 25 at all. At the same time, it moves up and down in the vertical cutout 61 provided on the formation surface 12c of the female spiral ridge 41a in the common male and female spiral ridges 41a and 41b for mounting the cup 14 and the cap 15 of the container base 12. Since it acts on the safety switch 27, it does not affect the attachment / detachment of the container member 50 to the container base 12 due to the reciprocation of the male spiral ridge 41b of the cup 14 or the cap 15 with respect to the female spiral ridge 41a. In the minimum required plane space.
[0038]
In particular, the vertically moving member 29 is placed on a path on which the male spiral ridge 41b for mounting on the container base 12 of the container member 50 enters along the female spiral ridge 41a as shown in FIG. As shown in FIG. 2A, the male spiral ridge 41b which has entered and has a projection 29a which is engaged and pushed down as shown in FIG. 2 (a). As described above, the vertically moving member 29 is in the notch 61 of the formation surface 12c of the female spiral ridge 41a in the container base 12, and its own protrusion 29a is moved from the formation surface 12c to the male spiral ridge 41b of the container member 50. 2A, when the male spiral ridge 41b enters along the female spiral ridge 41a due to the mounting of the container member 50, the male spiral ridge 41b engages with the male spiral ridge 41b to engage with the male spiral ridge 41b. ) Is pushed down as shown in ()) and thereafter stabilizes in its lowered position. Conversely, the depression is released by the retreat of the male spiral ridge 41b. Thus, the up-down moving member 29 can move up and down in response to the attachment / detachment of the container member 50 without interfering with the attachment / detachment operation of the container member 50 with respect to the container base 12 by the male and female spiral ridges 41b. In addition, in the state where the container member 50 is mounted on the container base 12, even if the container member 50 is removed from the container base 12, the vertically moving member does not independently project to the outside, and there is no fear of being caught by another.
[0039]
After the projection 29a of the vertically moving member 29 engages with the male spiral ridge 41b of the container member 50 and is pushed down, the projection 29a stably stays at a position along the lower surface of the male spiral ridge 41b, and They are arranged in the longitudinal direction of the strip 41a. At this time, as shown in FIG. 2, the projection 29a has a side shape substantially matching the cross-sectional profile of the female spiral ridge 41a. However, the male spiral ridge 41b of the container member 50 pushes down the projection 29a and does not interfere with the subsequent advance and retreat.
[0040]
The upward movement position of the projection 29a can be regulated, for example, by the upper end position of the notch 61. Of course, other methods may be used. In the example shown to perform such a regulation, the height is set such that the upper surface of the projection 29a substantially coincides with the lower surface of the female spiral ridge 41a. Correspondingly, the projection 29a forms a sliding surface 29b shown in FIG. 2 (b) having a slope or radius that lowers the side on which the male spiral ridge 41b enters and makes it easier to be pushed down. As a result, there is no inconvenience that the male spiral ridge 41b collides with the projection 29a and cannot be pushed down by engagement or is damaged.
[0041]
1 and 2 (b), the safety switch 27 is provided inside the main body 11 so as not to be exposed to the outside, and an operation hole provided on the receiving surface 11a of the main body 11 on which the container base 12 is placed. The push operation is performed by a vertically moving member 29 via an operation member 28 that moves up and down in the inside. The pushing operation of the safety switch 27 by the up and down moving member 29 is also a necessary condition that the container table 12 is placed on the main body 11 in a correct direction, so that use in an incorrect placing direction is prohibited. It will also be. In the illustrated example, the cup 14 or the cap 15 is mounted on the container base 12 by fitting a helicoid or a spiral ridge of a screw, and the helicoid or the screw is formed in two rows. The vertical movement member 29 is provided at two locations on the diameter line of the container base 12 in accordance with the two mounting directions of the container base 12.
[0042]
Further, as described above, when the protrusion 29 is pushed down by the male spiral ridge 41b, the vertical movement member 29 pushes the safety switch 27 to turn it on, and thereafter the male spiral ridge 41b continuously passes. By pushing, the pushing state is maintained. The pushing of the safety switch 27 due to the pushing down of the vertical moving member 29 is the same regardless of the timing at which the container member 50 is mounted, for example. However, when the container member 50 is being mounted, the motor 4 can be driven even though the container member 50 has not been mounted yet. In order to avoid such a state, the male spiral ridge 41b may engage with the projection 29a of the vertically moving member 29 and push it down at the final stage when the mounting of the container member 50 is completed.
[0043]
In the example shown in FIG. 4, in order to provide the vertically movable member 29 around the outer periphery of the seal portion 52, the lower surface of the seal packing 25 between the container base 12 and the container member 50 is viewed from below the container base 12, and the seal packing is provided. In response to the attachment / detachment of the container member 50 to / from the container base 12 via the reference numeral 25. Specifically, a recess 63 smaller than the width of the seal packing 25 is provided below the seal packing 25 of the container base 12 so that the head 29 c of the vertically moving member 29 faces the recess 63. At the upper position with the seal packing 25. As a result, when the container member 50 is mounted on the container base 12, the vertically movable member 29 is moved down, and the safety switch 27 can be pushed and closed.
[0044]
According to this, although the seal packing 25 is lifted by the vertical moving member 29, the vertical moving member 29 can be provided in the simplest and smallest plane space. Moreover, since the recess 63 is smaller than the width of the seal packing 25, the seal between the container base 12 and the container member 50 by the seal packing 25 is not impaired. Further, in the illustrated example, the vertical movement member 29 is configured to directly push the safety switch 27, so that the configuration is further simplified. However, the actuator 27a of the safety switch 27 is located in the concave portion 65 on the receiving surface 11a of the main body 11, and is less likely to receive an external force even when the container base 12 is removed.
[0045]
In the example shown in FIG. 5, an upper bent portion 29 d of a vertically moving member 29 is inserted and integrated into a part of the outer periphery of the seal packing 25, and the vertically moving member 29 is sealed by the seal packing 25 between the container base 12 and the container member 50. It is difficult to obstruct the portion 52.
[0046]
In the example shown in FIGS. 6 to 8, the vertically movable member 29 is integrally formed on an annular base material 71 sandwiched between seal packings 25 a and 25 b formed in two layers, and the base material 71 is sealed with the seal packings 25 a and 25 b At the same time, the container member 50 of the container base 12 is disposed on the outer peripheral portion of the bottom where the container member 50 comes into pressure contact, so that the vertically moving member 29 is unlikely to interfere with the seal portion 52. The vertically moving member 29 is provided in a rib shape at two places on the diameter line as shown in FIG. 8 so as to be able to face the safety switch 27 shown in FIG. 7 even if the container member 50 has two mounting directions as described above. I have to. Guides 71a, which are shorter than the up-down movement members 29, are provided at the remaining two places of the base material 71 where the up-down movement members 29 are not provided. By doing so, the base material 71 and, consequently, the vertical moving member 29 can be moved up and down stably and smoothly.
[0047]
Further, in this example, a safety cover 72 that covers the safety switch 27 while maintaining the non-pushed height by a spring 73 as shown in FIG. Thus, even if the container base 12 is mounted on the main body 11 and the container member 50 of the container base 12 is not mounted, the safety cover 72 pushes up and down the vertically moving member 29 by the bias of the spring 73, and the safety The switch 27 is set free and kept in the non-pressed state. That is, the safety switch 27 is set free on the side of the main body 11 so that the normally open state can be maintained. Therefore, even if the container base 12 is removed, there is an advantage that it is hard to receive an inadvertent pushing operation. In addition, in the example shown in the figure, a guard wall 74 higher than both sides of the safety cover 72 is provided so as not to hinder the pushing by the up-down moving member 29. Can be prevented. However, the same effect can be obtained by providing the safety cover 72 in the concave portion of the main body 11 instead of the guard wall 74. When the container member 50 is mounted on the container base 12 mounted on the main body 11, the vertically moving member 29 overcomes the bias of the spring 73 to lower the safety cover 72, and pushes the safety switch 27 to close. Can be achieved. Although the downward movement of the safety cover 72 is transmitted to the safety switch 27 via the operation member 28, it may be transmitted directly.
[0048]
A cord reel 201 located below the motor 4 is provided in the bottom of the main body 11 so that a power cord (not shown) can be wound up and fed out.
[0049]
The example shown in FIG. 9 will be described in detail. As described above, a mixer having a mill blade 31 in addition to the mixer blade 3 has a lowering function. Normally, the mixer blade 3 has a sharp edge on the edge in the rotation direction, but the mill blade 31 does not have such a blade or does not have a sharp blade. That is, the mixer blade 3 cuts the material, while the mill blade 31 mainly uses a crushing action by crushing. In this connection, the rotation of the mill function is often set to about 20,000 rpm, which is higher than that of the mixer function. Therefore, it is preferable to switch the number of rotations depending on the difference in the mill function in addition to the difference in the mixer function and the lowering function. The mill function is also frequently used and does not cause a decrease in the usage rate of the cooking machine, and can be selected and used with a simple addition without special labor, thereby giving convenience to the work user.
[0050]
The mixer blade 3 and the mill blade 31 are provided with a common boss portion 32 so as to be detachably attached to a screw portion 33a at the upper end of a rotating shaft 33 provided at the bottom of the container base 34. As a result, the mixer blade 3 and the mill blade 31 and the grater 5 that interferes with the mixer blade 3 and the mill blade 31 can be selectively used by being detachably mounted on the screw portion 33a and replaced. The container base 34 has a container shape that is fitted and removably mounted inside the upper portion of the main body 11, and supports the rotating shaft 33 with a bottom bearing 35. The container base 34 may have a skirt wall that is fitted and mounted on the outer peripheral portion of the upper end of the main body 11. At the lower end of the rotating shaft 33, the container base 34 is fitted to the upper part of the main body 11, and has connection portions 36 a and 36 b between the motor 4 and the container base 34.
[0051]
The grater 5 has a rotary shaft 134 that rises from the mounting position of the mixer blade 3 and the mill blade 31 to form the storage space 6 and is mounted on the screw portion 33a. The projection shaft 134a is provided. The protruding shaft 134a serves as a knob for attaching and detaching and holding the grate plate 5, and also enhances the grate effect by removing material from a central portion where no grate operation is performed.
[0052]
The container base 34 is attached to the outer periphery of a portion extending above the upper end of the main body 11 so that a cap 37 as a mixer function container member 50 is detachably attached to the screw fitting portion 38 so as to be detachable. Of the container 1. In addition, by mounting the cap 39 as the container member 50 shared for the mill function and the lowering function on the inner periphery of the container base 34, specifically, the inner periphery of the bottom portion, so that the cap 39 can be attached and detached with the screw fitting portion 41, The container 1 is used for both the mill function and the lowering function. This skillfully satisfies the mounting structure corresponding to the fact that the cap 39 is smaller than the cap 37 and has a higher function of preventing material from escaping. The cap 37 may be provided with a lid as a cup as in the above example.
[0053]
The cap 37 for the mixer function, the cap 39 for the mill function, and the cap 39 for the lowering function as described above are all attached to the container base 34, and the work obtained by each function is transferred to the main body 11 together with the container base 34. , And can be carried and handled independently as a closed container 1. As described above, since the caps 37 and 39 as the container member 50 are detachably attached to different positions of the container base 12, the cap 52 is used as the seal portion 52 between the container member 50 and the container base 12. It comprises a seal packing 42 between 37 and the container base 34, and a seal packing 43 between the cap 39 and the container base 34. Specifically, the seal packing 42 is provided on the step 12 d provided below the screw fitting portion 38 on the inner periphery of the container table 12, and the lower end of the cap 39 attached to the container table 12 is The seal packing 42 is sandwiched between the seal packing 12d and the sealing seal 12d to seal between the two. The seal packing 43 is provided on the outer periphery of the bottom of the container base 12, and the seal packing 43 is connected to the bottom of the container base 12 by the lower end of the cap 39 attached to the fitting portion 41 near the bottom of the inner circumference of the container base 12. It is sandwiched between and sealed.
[0054]
As described above, since the seal portion 52 of the present example is provided with the two seal packings 42 and 43 at different positions, the vertically moving member 29 disposed around the outer periphery of the seal portion 52 is different from the outermost seal packing 42. The safety switch 27 is pressed down and closed in response to the mounting of the caps 37 and 39 which are the container members 50. As a result, safety and proper use can be achieved without affecting the two seal portions 52 formed by the two seal packings 42 and 43. In order to provide such a vertically moving member 29, the container base 12 has a shape in which a part in the circumferential direction has a bulging portion 81 bulging radially outward. Upon fitting of the container base 12 having such a locally bulged portion 81 and the main body 11, the container base 12 can be positioned in the rotational direction. In the illustrated example, the vertically moving member 29 responds to the vertical mounting operation of the lower end of the cap 37, and responds to the vertical mounting operation of the flange 39a provided on the outer periphery of the cap 39. It is.
[0055]
In addition, the structure shown in FIGS. 4-8 can be employ | adopted for how to operate the up-down movement member 29. FIG. When the fitting portion 38 or 41 is used for mounting the caps 37 and 39, the vertical moving member 29 which responds to the helicoid or the spiral ridge of the screw can be provided at that portion.
[0056]
In the present embodiment, the motor 4 is smaller than the outer diameter of the main body 11, and a power cord 83 when not in use is accommodated by using an empty space 82 therebetween. . The motor 4 is provided with a synthetic resin cover 84 so that the power supply cord 83 can be safely wound around the cover 84. For this purpose, the bottom of the main body 11 is formed by a removable bottom lid 85. The bottom cover 85 can be attached and detached using a fitting portion 86 formed by screws with the outer periphery of the lower end of the cover 84. Thus, even if the outlet 87 of the power cord 83 is cut from the open end at the lower end of the body of the main body 11, it does not affect the mounting of the bottom lid 85. If the bottom cover 85 is fitted into the opening at the lower end of the main body 11 where the draw-out opening 87 is located, the bottom cover 85 may fall off. In addition, since the drawer opening 87 cut from the lower end is opened when the bottom cover 85 is removed, the drawer opening 87 can be easily pulled out simply by fitting it in without passing through the power cord 83.
[0057]
FIG. 10 shows a modification of the power cord storage structure in the example shown in FIG. The bottom lid 85 has a peripheral wall 85a that forms the lower end of the body of the main body 11. Thus, when the bottom cover 85 is removed, the lower end of the cover 84 of the motor 4 is also exposed to the side, so that the work of winding and removing the power cord 83 can be easily performed. In this connection, a peripheral wall 84a extending from the lower end of the cover 84 to the stationary portion formed by the bottom lid 85 of the main body 11 is provided, and the winding area of the power cord 83 is extended downward to further facilitate winding. . At the same time, an outer reel-like flange 84b is provided at the lower end of the peripheral wall 84a to facilitate holding the wound power cord 83. As a result, the wound power cord 83 is less likely to collapse even when the bottom lid 85 is removed, making it easier to handle. Further, a fitting portion with a screw to the bottom cover 85 is provided on the inner periphery of the peripheral wall 84a.
[0058]
FIG. 11 shows another modification. A winding wall 86 around which the power cord 83 is wound is provided so as to be vertically movable around the outside of the cover 84. Thus, the winding wall 186 can be pulled out from the lower end of the main body 11 when the bottom lid 85 is removed, and the power cord 83 can be easily wound and removed. The winding wall 186 can be moved up and down by fitting one projection 86 a provided at three or more places in the circumferential direction on the inner circumference thereof into the vertical groove 84 c of the cover 84. However, the specific structure is not particularly limited.
[0059]
FIG. 12 shows another modification. This example has the features of the bottom lid 85 shown in FIG. 10 and the features of the winding wall 186 shown in FIG.
[0060]
FIG. 13 shows another example. In this embodiment, the plug 83a of the power cord 83 is inserted and held in a hole 84e of a peripheral ceiling portion 84d formed by the cover 84 while having the features of the bottom cover 85 shown in FIG. Thereby, the power cord 83 wound around the cover 84 is stabilized between the base 83b pulled out from the cover 84 and the plug 83a.
