Description

[Detailed Description of the Invention] The present invention provides a stand mixer that is convenient to use and easy to assemble.

An embodiment of the present invention will be described below based on the drawings.

Reference numeral 1 designates a stand mixer according to the present invention, which includes a stand 2 containing a motor, a gear box 4 that is detachably attached to the stand with a clamp 3, and a stand hood mixer attachment 5 that is detachably attached to the gear box. It becomes more.

A pedestal section 6 is provided at the bottom of the stand 2.

A rotary table 8 on which a cooking container 7 is placed is pivotally supported on the table part 6.

A coupling 9 driven by the motor protrudes from the upper surface of the stand 2.

A pivot shaft 10 is formed on the upper side of the stand opposite to the side surface on which the base portion 6 is formed.

A group of reduction gears is housed inside the gear box 4, and the input end of the gear group is connected to the coupling 9 when the gear box is mounted on the stand.

The attachment 5 is attached to the gear box 4 with a screw 11 and connected to the output end of the gear group.

The attachment 5 is supported so as to extend over the cooking container 7 in the attached state.

An output part of the attachment is formed on the projecting lower surface, and a pair of kneading hooks 12 are attached to the output part.
It is suspended into the container 7.

The material stored in the container 7 is kneaded by the kneading hook 12 which is rotated by the rotational force of the motor.

A mixing beater or the like can be attached to the output section in place of the kneading hook 12.

A hook 13 that is hooked to the pivot shaft 10 is formed in a portion of the gear box 4 that is connected to the pivot shaft 10.

Therefore, when the clamp 3 is removed, the gear box 4 can rotate about the pivot shaft 10 in the elevational direction.

When rotated, the kneading hook 12 is pulled out from the container 7 and replaced with the beater etc.
The container 7 can be easily removed from the container 7 and other materials can be added into the container 7.

The hook 13 is provided with a tongue piece 15 having a pivot pin 14 projecting from its center, and a hook part 16 for hooking onto the pivot shaft 10.

The gear box 4 has a recess 17 with an open bottom where the hook 13 is attached.

On both sides of the recess 17 are formed an insertion hole 18 into which the pivot pin 14 engages, and a stepped portion 19 against which the tongue piece 15 abuts.

Furthermore, cutouts 20 are formed in the lower edges of both sides of the recess 17 so as to cover the pivot shaft 10 .

The hook 13 can be pivotally attached by fitting the pivot pin 14 into the insertion hole 18 using the elasticity of the tongue piece 15, and when the tongue piece 15 comes into contact with the stepped portion 19, the hook 13 This serves as a guide for rotation around the pivot pin 14.

A spring 2 is provided between the inner surface of the recess 17 and the hook 13.
1 is interposed therebetween, and by imparting rotational force to the hook 13 by the spring 21, the hook between the pivot shaft 10 and the hook 16 is strengthened.

A rib 22 is formed at the upper end of the hook 13 to abut against the upper edge of the recess 17, and the rotation of the hook 13 by the spring 21 is restricted within a certain range.

The gear box 4 is equipped with a support device for holding the gear box 4 in a rotated state in the elevation direction.

The support device includes a mounting plate 25 fixed to both sides of the gear box bottom plate 23 with screws 24, a substantially fan-shaped support piece 27 that is pivoted on a lower bearing 26 of the mounting plate and hangs down by its own weight, and the mounting plate 27. A cam plate 29 is pivotally supported by an upper bearing 28 of the plate and rotates in a direction to retract the support piece, a spring 30 biases the cam plate in a direction where it is not caught on the support piece, and a knob 31 is used to hold the cam plate. It consists of a connecting shaft 32 that rotates in conjunction with each other.

The fan-shaped support piece 27 is pivotally supported, and its arcuate portion comes into contact with the upper surface of the stand 2 when it hangs down.

Since the support piece 27 comes into contact with the upper surface of the stand, the gear box 4 is held in a state where it is rotated in the elevation direction.

Further, since the support piece 27 hangs down due to its own weight, it can be reliably supported simply by rotating the gear box.

Furthermore, in this embodiment, as shown in FIG. 6, the middle of the arc portion of the support piece 27 comes into contact with the support piece 27, so that the support piece 27 must resist the frictional force between the top surface of the stand and the support piece in order to retreat into the gear box. The support piece does not have to be rotated and is retracted into an unnecessary window, and the gear box does not rotate in the depression angle direction, making it easy to use and safe.

A regulating pin 34 is protrudingly provided on a side 33 of the support piece 27 located inside the gear box 4, which abuts against the lower opening edge of the gear box and prevents the support piece 27 from rotating due to its own weight beyond a certain level. .

Further, a projecting piece 35 is formed on the side edge 33, and retaining pins 36 are provided projecting from both sides of the tip of the projecting piece 35.

The engagement pin 36 is inserted into an arcuate slit 37 formed in the mounting plate 25, and the slit 37 restricts the range of rotation of the support piece 27.

The cam plate 29 is provided with a locking piece 38 that is hooked on the engagement pin 36 when rotated, and when the engagement pin 36 is pushed by the locking piece 38, the support piece 27 is rotated and retracted into the gear box 4.

A protrusion 39 is provided on the cam plate 29, and a pair of protrusions 40 are provided on the upper bearing 28, with which the protrusion comes into contact when the cam plate 29 rotates.

Therefore, when the cam plate 27 is unable to rotate against the elastic force of the spring 30, the protrusion 39 is moved against the one protrusion 40.
When the cam plate 27 is about to be rotated by the spring 30, the protrusion 29 comes into contact with the other protrusion 40 and its rotation is kept constant. regulated within a range.

Since the cam plate 27 is rotated in conjunction with the connecting shaft 32, the cam plate 27 can be rotated smoothly with one hand.

Therefore, when rotating the cam plate 27 using the knob 31, the gear box 4 can be lifted up a little with the other hand to release the contact between the stand 2 and the support piece 27.
No. 1 rotational operation does not require a large amount of force.

Further, since the support device is not directly assembled into the gear box 4, but is assembled outside the gear box, assembly can be easily performed.

In this embodiment, the projections 40 are formed on both sides of the upper bearing 28 of the mounting plate 25, and the mounting plate 25 is commonly used, which reduces assembly errors and facilitates parts management. .

As described above, the present invention has a stand on which a cooking container is placed and supports a stand mixer main body projecting above the container, and the main body can be rotated in the elevation direction.
The main body includes a support piece that hangs down under its own weight from both sides of the bottom surface of the main body and comes into contact with the top surface of the stand, a cam plate that rotates the support piece in a direction to retract it, and a cam plate that urges the cam plate in a direction where it will not be caught by the support piece. The mixer is equipped with a spring that rotates the cam plate, a connecting shaft that rotates the cam plate in conjunction with the knob, and a separate mounting plate that mounts and supports each of the parts, and the assembly of each part is completed before incorporating it into the main body of the mixer. It is possible to easily assemble the cam plate, and since the cam plate is rotated by a connecting shaft, it can be performed with one hand, which has great practical effects.
