Description

[Detailed description of the invention] This invention has two output shafts: a first output shaft that is directly connected to a motor and rotates at high speed, and a second output shaft that is decelerated and rotates at a low speed. In addition, in a compound cooking device that is selectively attached to the second output shaft, a clutch mechanism is provided between the speed reducer and the second output shaft, and when a cooking device such as a mixer is engaged with the first output shaft, The present invention relates to a composite cooking device in which the cooking body causes the clutch mechanism to be in a non-engaged state.

In general, a multi-purpose cooking device has a food processor that slices and chops vegetables etc. using rotating blades, a juicer, a mixer, and other cooking devices that are selectively attached to the high-speed and low-speed shafts of the main body of the cooking device. It can be used for cooking, but as mentioned above, it has two axes, so a safety device is essential.If you want to use one axis, the motor must be switched on unless the other axis is covered. Safety devices have been devised to prevent this from happening.

In addition, some devices have a structure in which a clutch mechanism is used to transmit or cut off the rotational force of the motor to the shaft.Cookers equipped with a conventional clutch mechanism are equipped with a clutch mechanism on the high-speed shaft and operate the clutch mechanism. The knob of the operating lever protrudes from the surface of the cooker body.

Therefore, there are problems with sliding during engagement and disengagement of the clutch mechanism during high-speed rotation, large noise and vibration, and low durability.

Moreover, since the knob of the operating lever protrudes from the surface of the cooking device main body, the configuration becomes complicated and the cost increases.

Next, the operation of the above embodiment will be explained.

The right side of the dashed-dotted line in FIG.
The left side of the dashed-dotted line shows a state in which the cover 50 is attached to one of the mounting parts 6 and a state in which the mixer cooking body 45 is turned upside down and placed on the stepped part 1' of the cooking device main body 1 to be attached. .

First, when cooking with the food processor cooking body 54, the container 55 of the food processor cooking body 54 is fitted into the other attachment part 16 of the cooking device main body 1, and the rotating body
is inserted into the second rotation transmitting part 53, and the lid 58 is attached to the container 55.

In this state, that is, in the state where the first rotation transmission section 5 is exposed, the safety switch 33 will not turn on.
Motor 2 does not rotate.

Next, when the cover 50 is attached to one mounting part 6 and the first rotation transmission part 5 is closed, the switch operation part 33 is pressed by the cover 50 and moves downward, the safety switch 35 is turned on, and the motor is turned on. 2 is driven.

At this time, the clutch operating portion 38 loosely inserts the coil into the notch 52 of the cover 50 due to the biasing force of the spring 41, so that the clutch body 22 is biased downward by the leaf spring 32, and each driven side joint pawl 24 is As shown in FIG. 3, the clutch mechanism is engaged with each driving side joint pawl 20, and the rotation of the motor 2 is caused by the small diameter pulley 7.
, the rotation speed is reduced to a predetermined speed by the drive belt 19 and the large-diameter pulley 17, and is transmitted to the second rotation transmission section 53,
Further, the rotary blade 57 rotates via the rotary body 56 and cuts the food to be cooked that is introduced from the input tube portion 59 by the push rod 60.

In addition, lemons can be squeezed using the lemon squeezer 51 of the cover 50 attached to one mounting portion 6.

Next, when performing mixer cooking using the mixer cooking body 45, when the cover 50 is removed from one mounting part 6, the safety switch 33 is turned off and the first rotation transmitting part 5 is turned off.
rotation stops.

Then, when the mixer cooking body 45 is placed on one mounting part 6 and rotated and clamped, the switch operation part 35 is pressed by the cooking table 46 and the safety switch 33 is turned on, and at the same time, the clutch operation part 38 is turned on to coil the coil. It is moved downward against the urging force of the spring 41 and the leaf spring 32, the clutch actuating plate 28 rotates about the pivot pin 30, and the clutch auxiliary ring 25 is moved upward by the arm portion 31 of the clutch actuating plate 28. .

Since the clutch auxiliary ring 25 is prevented from being removed from the clutch body 22 by the C ring 27, the clutch body 22
is moved up while sliding on the second output shaft 14 until it contacts the upper part of the elongated hole 21, the driven side joint pawl 24 disengages from the driving side joint pawl 20, and the clutch mechanism becomes disengaged, causing a large The rotation of the pulley 17 of the diameter is the second output shaft 14
is not transmitted.

At this time, the elastic body 22 d on the upper surface of the clutch body 22 is joined to the metal bearing 15 , and the large diameter pulley 17 is connected to the metal bearing 15 via the bearing 18 .
The friction between the second output shaft 14 and the second output shaft 14 causes the second output shaft 14 to
This prevents the pulley 17 from rotating together with the large diameter pulley 17.

By the way, the composite cooking device of the above embodiment has various advantages as described above.

That is, since the clutch mechanism is interposed between the large-diameter pulley 17 that rotates at a low speed and the second output shaft 14, the noise or vibration caused by sliding etc. is small, the durability is high, and the system is Moreover, when the clutch mechanism is in the engaged state, the shaft portion 22b of the clutch body 22 and the clutch auxiliary ring 25 are configured to slide, so rotational force is not directly transmitted to the clutch actuating plate 28 of the clutch mechanism, and vibration noise is generated. is further reduced.

When storing, the J mixer cooking body 45 is turned upside down and placed on the step 1' of the cooking device body 1, and the lid body 49 is placed on the cooking table 4.
6, it does not require a large storage space, and since the diameter of the internal part of the motor 2 of the cooker body 1 is reduced, the space in which the driving sound of the motor 2 reverberates is reduced. Therefore, there is no need to provide a muffling tube or the like, and costs can be reduced.

Furthermore, during assembly, the switch operation section 35 and the clutch operation section 38 are attached to the top surface of the cooking device main body 1 so as to be movable up and down, and the clutch mechanism and the clutch operation plate 2
The complete chassis, in which the transmission mechanism consisting of 8 etc., the safety switch 33 etc. are fixed to the chassis 8, can be inserted and fixed from the bottom of the cooker main body 1, so it is easy to set the stroke adjustment of both operating parts 35 and 38. The assembly and workability are greatly improved.

Note that the means for preventing the second output shaft 14 from rotating together with the large-diameter pulley 17 when the clutch mechanism is in the disengaged state is not limited to the above-mentioned embodiment, and for example, as shown in FIG.
A pin 61 is inserted through the second output shaft 14 at right angles to the axial direction, and a plurality of glue holes 2 are formed radially on the upper surface of the shaft portion 22b of the clutch body 22, so that the rib 62 and the pin 61 are in contact with each other. Alternatively, the fifth
As shown in the figure, a ring 63 having a wedge-shaped cross section is fixed to the second output shaft 14, and the shaft portion 2 of the clutch body 22 is fixed to the second output shaft 14.
An annular notch 64 is formed on the upper surface of 2b, and a ring 63 is formed.
may be fitted into the notch 64 to increase the frictional force.

Further, as shown in FIG. 6, a plurality of notches 65 are formed in the outer surface of the portion of the cooking device main body 1 in which the motor 2 is installed, downward from one mounting portion 6, and the mixer cooking body 45
A plurality of glues 166 corresponding to the notches 65 are formed on the inner surface of the mixer cooking body 45, and each rib 66 is fitted into the notch 65, so that the mixer cooking body 45 is attached to the stepped portion 1' of the cooking device main body 1.
By placing the mixer cooking body 45 on the cooking device main body 1, the stability of the mixer cooking body 45 during use and transportation is further improved.

As described above, according to the composite cooker of this invention, the first output shaft is rotated at high speed by the motor built into the cooker body, and the rotation of the motor is transmitted through the reduction gear and clutch mechanism to rotate at low speed. a second output shaft that is connected to the first or second output shaft; a cooking body such as a juicer, mixer, or food processor that is selectively attached to the cooking device main body so as to be connected to the first or second output shaft; Operates when connected to the shaft,
By including an operating section that connects and disconnects the clutch mechanism and an operating section that turns on the safety switch of the motor power circuit, the clutch mechanism is installed between the reduction gear and the second output shaft that rotates at a low speed, thereby reducing noise and noise. ``Vibration can be made very small.

Furthermore, since the clutch mechanism and safety switch are activated when the cooker is attached, it is easy to operate and safe.

Note that by providing a cover that covers the first output shaft and turns on the safety switch, the motor will not be driven when the rotation transmission section is exposed, further improving safety.

If a lemon squeeze part is formed on the cover, it will be practical for cooking.Furthermore, the diameter of the part of the cooker body where the motor is housed will be reduced, and a step part will be formed on which the upside-down mixer cooking body will be attached. In this case, the storage space is small, and the space for reverberation of the driving sound of the motor is reduced, and noise can be reduced without using a muffling tube or the like, and costs can be reduced.

Furthermore, by forming notches and ribs that engage with the cooking device main body and the cooking body, respectively, stability during use and transportation is further improved.
