Description

[Detailed explanation of the idea] (b) Industrial application fields The present invention relates to a machine that can be used as both a mixer and a mixer.

(B) Prior Art In general, a dielectric mixer/mixer is configured to operate at a low speed when used as a dielectric, and to operate at a high speed when used as a mixer. If the rotating body is operated at high speed when used as a pump, it is extremely dangerous due to unbalance of the rotating body, and there is a risk of damage to the pump attachment.

As a means to solve this drawback, conventional
- In Publication No. 14306, by providing a changeover switch that always forms a high-speed rotation circuit for the motor and forms a low-speed rotation circuit for the motor when the diversion attachment is attached, it is automatically activated when used as a diversion. A device that switches to low-speed operation is known.

According to this conventional example, if the changeover attachment is not fully installed, there is a risk that the changeover switch will not change, resulting in high-speed operation.

(c) Problems to be solved by the invention In view of the above-mentioned drawbacks, the object of the invention is to reliably prevent high-speed operation when used as a regulator.

(d) Means for solving the problem The present invention forms a constant low-speed rotation circuit of the motor,
The present invention is characterized in that it is equipped with a changeover switch that forms a high-speed rotation circuit for the motor when the mixer attachment is attached to the base.

(E) Effect By using the above means, even if the installation of the Juuser attachment on the base is incomplete, the selector switch always forms a low-speed rotation circuit for the motor, so when used as a Juuser, the low-speed rotation circuit is always formed. Driving is done.

(F) Embodiment An embodiment of the present invention will be described with reference to FIGS. 1 to 5. The one shown in the figure is a combination pump and mixer, and 1 has a built-in motor 2 and a drive shaft 5 having a drive-side connector 4 at its tip protrudes upward from an opening 3 on the top surface. Reference numeral 6 denotes a first engaging protrusion formed around the opening 3 on the upper surface of the base 1, into which the mixer attachment M is fitted. Reference numeral 7 denotes a second engagement protrusion formed on the outside of the first engagement protrusion 6, into which the attachment J is fitted.

The mixer attachment M has a well-known structure, and has a cutter 8 fixed to its upper end as shown in FIG.
A trapezoidal base with an open bottom surface, which rotatably supports a rotating shaft 10 to which a first driven connector 9 connected to a driving connector 4 is fixed at its lower end, and whose lower end fits into a first engaging protrusion 6. It consists of a part 11 and a bottle part 12 coupled to this base part 11. As shown in FIG. 2, the juicer attachment J includes a receiver 14 having a skirt portion 13 at its lower end that fits into the second engaging protrusion 7, and a lid that removably covers the upper opening of the receiver 14. 15, and a filter member 18 which is located inside the cooking case 16 and has a second driven side connector 17 connected to the drive side connector 4 below. Reference numeral 19 denotes a clamp that detachably fixes the cooking case 16 to the base 1.

Reference numeral 19 denotes a switch operating rod whose upper part protrudes upward outside the protrusion 6 on the upper surface of the base 1, and which is constantly supported by a spring body 20.
is energized upward by the mixer attachment M.
It is provided at a position where it is pushed downward by the lower end of the stand part 11 when it is attached to the base 1. 21 is a single-pole, double-throw micro-type changeover switch installed below the operating rod 19 in the base 1, and a normally closed contact 21b when the operating rod 19 moves upward.
This closes the normally open contact 21a during downward movement, and is connected to the motor 2, etc., as shown in FIG.

That is, the fixed contact 21c of the changeover switch 21 is connected to one end of the AC power source E via the operation control switch 22 that switches between stopping and speeding the motor 2, and the normally closed contact 21b is connected to one end of the AC power source E via the half-wave rectifier diode 23. The normally open contacts 21a are directly connected to the other end of the AC power source E, respectively.

According to the above configuration, when the mixer attachment M is attached to the base 1 when used as a mixer, the operating rod 19 is moved down by the base 11, and the changeover switch 21 is moved to the opposite side as shown in FIG. A high-speed circuit is formed in which a full wave of alternating current is applied to the motor 2, and the motor 2 rotates at high speed to perform mixer cooking.

When the lever attachment J is attached to the base 1 when used as a lever, the operating rod 19 is not pressed, so the changeover switch 21 is in the switching state shown in FIG. A low-speed rotation circuit is formed in which the electric current is applied to the motor 2, and the motor 2 rotates at a low speed to perform juice cooking.

This controller attachment J when operating the controller
Even if the attachment to the base 1 is incomplete, the changeover switch 21 is not changed by attachment of the changer attachment J, so the motor 2 does not operate at high speed as in the conventional case.

(g) Effects According to the present invention configured as described above, even if the lever attachment is not fully installed when used as a lever, high-speed operation will not occur, resulting in improved safety. is large.
