Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a cooking machine that processes foods such as meat and vegetables using a rotating cutter.

Conventional technology Conventionally, a cooking machine such as a mixer has two cutters rotatably fixed to the bottom of a container, and the cutters are rotated at high speed by an electric motor. It involves placing ingredients together in a container, finely pulverizing and stirring the ingredients, and preparing drinks or cooking. A food processor is a cooking device similar to a blender. Food processors are primarily used for preparing food, such as chopping vegetables, grilling meat, grilling fish, grating daikon radish, and long yam. Its structure uses pulleys, gears, etc. to slow down the rotation of the electric motor.
It transmits rotation to the cutter inside the container and cooks the ingredients inside the container.

The fitting between the lid and the container of these cooking machines is as shown in FIG. The lid 6 is inserted into the container 5 while being bent, and is held in the container by the elastic force of the lid 6.

Problems that the invention aims to solve When holding a lid on a container using the elastic force of the lid, the outer diameter of the lid should always be aligned with the inner diameter of the container while the lid is inserted into the container. A shrinking force acts, and due to environmental conditions such as ambient temperature and humidity, as well as changes over time, the outer diameter of the lid gradually decreases, causing the lid to lose its holding power and cause the container to be turned upside down. There was a risk that the lid would come off the container just by doing so.

Also, in the case of mixers and food processors,
If the cutter is turned on by the electric motor when the switch is turned on with the container placed on the main body and the lid removed from the container, the cutter will rotate when the cutter is rotated by the electric motor. In cases where chopsticks or the like are placed inside the container, there is a risk of injury or the material inside the container spilling out.

Means for Solving the Problems The present invention was made in order to solve the above-mentioned problems with conventional cooking machines. The engaging portion and the recessed portion are each provided with a pusher for pressing the lid onto the container from below, thereby reliably fixing the lid to the container.

Function: When the lid is engaged with the outer periphery of the container and further locked into the engaging portion, the push rod is pushed down and then engaged with the slider. This ensures that the lid is connected to the container. Next, when the slider is operated, it is disengaged from the lid, and at the same time, the lid is removed from the container by the upward biasing force of the push rod. The slider can be operated while holding the handle, and the action of the push rod is automatically performed.

When the cutter is engaged with and fixed to the engaging body 57 of the cutter shaft 55 and the lid 6 is placed on the accommodating portion 15, the handle of the cutter and the lower end of the convex portion 28 of the lid 6 are slightly separated. It is located with a large gap.

The operation of this embodiment having the above configuration will be explained.

A mixer cutter 62 is set on the shaft 55 in the container 5, and the material is put into the storage section 15. The lid 6 is placed on the upper part of the accommodating part 15 so that the recess 35 fits with the outer peripheral edge 34 of the accommodating part 15, and the notch 47 of the engaging part 36 is engaged with the locking body 48 of the slider 40. Then, the lid 6 is fixed to the housing part 15. Since the inclined portion 49 and the inclined surface 50 are provided on the bottom of the engaging portion 36 and the upper surface of the locking body 48, the engaging portion 36 is locked using the point where the outer peripheral edge 34 and the recess 35 engage as a fulcrum. As the lid 6 is moved downward while in contact with the body 48 , the sloped portion 49 of the engagement portion 36 presses the sloped surface 50 of the locking body 48 inwardly, and the slider 40 presses the coiled spring 41 .
The slider 40 moves inward, that is, toward the center of the container 5, against the biasing force of the coil spring 41, and then returns to the outside due to the biasing force of the coil spring 41, and engages with the notch 47 of the engaging portion 36. The stopper 48 is engaged.
At this time, the pituitary body 37 of the lid 6 pushes down the upper end of the push rod 26 against the biasing force of the coil spring 27.

By placing the container 5 on the main body 1, the driving side coupling 9 and the driven side coupling 61 are fitted, and the rotation of the rotating shaft 8 is transmitted to the mixer cutter 62 via the shaft 55. Ru. Further, since the push-down rod 26 is in a depressed state against the urging force of the coil spring 27, the push-down rod 26
6 pushes down the operating rod 14 against the biasing force of the operating spring 13, presses the operating button 12 of the micro switch 4, the micro switch 4 becomes closed, and by turning on the main switch 3,
It is ready to drive at any time.

In the case of the cutter 62 for a mixer, solid materials and liquid materials are mainly put together. The solid material is pulverized and cut by the mixer cutter 62 while being circulated together with the liquid material by the circulating flow of the liquid material. The rib-shaped protrusions 93 provided inside the housing portion 15 act as resistance in the rotational direction of the circulation of the material, increasing the relative rotational speed difference between the material and the mixer cutter 62. During operation, the material is stirred by the cutter 62 for the mixer, and due to centrifugal force, the material swells higher toward the outer periphery. If the amount of material is large, the material swells to the point where the upper end of the container 15 and the lid 6 are in contact, and the liquid tightness is reduced. If this is not done, there is a risk that the liquid material will leak from the area where the upper end of the accommodating part 15 and the lid 6 contact due to the pressure of the material. There is no risk of liquid material leaking. Also, while driving. Since the liquid material is abraded in the container 15 by the rotating cutter 62 for the mixer, the water droplets adhere to the inner wall of the lid 6, but the water droplets adhering to the vicinity of the small hole 29 form a protruding shape due to surface tension. It travels through the section 28 and is led to the housing section 15 from its lower end. The material is finely cut and crushed,
After the operation is finished, the lid 6 is removed and the workpiece is transferred to another pot or container.

When removing the lid 6, when the outer circumferential side of the slider 40 is pressed toward the center of the container 5, the notch 47 of the engaging portion 36 and the locking body 48 are disengaged, and the lid 6 is moved by the biasing force of the coil spring 27. It is in a state where it is pushed upward via the push rod 26. When the lid 6 was removed, the push rod 2 was pressed by the pituitary gland 37.
6 is open, the push rod 26 and the actuating rod 14 are pressed upward by the coil spring 27 and the actuating spring 13, respectively, and the actuating button 12 of the micro switch 4 is opened and the main switch 3 is turned on. Also, the electric motor 2 does not rotate. Also, when the container 5 is removed from the main body 1 with the lid 6 attached to the container 5, the operating rod 14
However, even if the actuating spring 13 presses upward, the actuating button 12 is released, and the main switch 3 is turned on, the electric motor 2 does not rotate.

According to the embodiment, since the lid 6 is engaged with the outer circumferential edge 34 of the storage portion 15 and locked on the slider 40 to be fixed to the container 5, the pressure and vibration of the material during operation and the ambient temperature are avoided. environmental conditions such as humidity,
There is no fear that the lid 6 will lose its holding power due to aging and the lid 6 will come off the container 5.
The lid 6 is securely fixed, and when the lid 6 is removed, the lid 6 can be easily removed by pressing the outer peripheral side of the slider 40 toward the center of the container 5 with a simple operation. It is possible.

Furthermore, the notch 47 of the engaging portion 36 and the locking body 48
When it is disengaged, the lid 6 is pushed upward via the push rod 26 by the biasing force of the coil spring 27, making it easier to remove the lid 6.

Further, a push rod 2 is provided between the handle 21 and the housing portion 15.
6 is clamped so as to be vertically movable, so that an operating rod 1 that moves up and down in conjunction with the up and down movement of the push rod 26 is attached to the main body 1.
4 and the micro switch 4, which opens and closes in conjunction with the vertical movement of the operating rod 14, are fixed, the electric motor 2 will not rotate even if the main switch 3 is turned on while the lid 6 is removed. Therefore, when the hand, spoon, chopsticks, etc. are placed in the storage part 15,
The cutter may suddenly rotate and cause injury.
It is also possible to configure the push-down rod 26 as part of a safety device, without the risk of spilling the material in the container 15 to the outside.

Effects of the invention As described above, according to the invention, by engaging the lid with the outer periphery of the container and locking it to the slider and fixing it to the container, the pressure and vibration of the material during operation, the ambient temperature, etc. The lid must be securely fixed to the container without coming off due to environmental conditions such as humidity or aging, and can be easily removed by operating a slider. At the same time, by pressing the push rod upward, when the lid and slider are disengaged, the lid is pushed upward by the push rod, making it easier to remove the lid. In addition, the present invention provides a cooking machine in which the push rod can also be configured as a part of the safety device.

As described above, according to the present invention, the concave part of the lid is engaged with the outer periphery of the container, and the engaging part of the lid is locked with the locking body of the slider to be fixed to the container, so that the material can be removed during operation.
