Leaving these things as is is of course unhygienic and may cause problems such as rotting and emitting strange odors, so be sure to clean the inside of them to remove dirt after use. Should.

However, the mixer's cutter is a sharp blade, and it is extremely dangerous to insert your hand into the area to remove dirt.

[Problems to be Solved by the Invention] As described above, in the mixer, dirt such as vegetable fiber pieces tends to adhere particularly around the cutter. The cutter is a very sharp knife and is dangerous, so it is necessary to avoid inserting your hands around it for cleaning.

SUMMARY OF THE INVENTION An object of the present invention is to provide a mixer that is equipped with a means for removing dirt around the cutter without inserting one's hand into the area after using the mixer.

More specifically, the purpose is to provide the mixer with a means of pouring cleaning water into the container and causing the water to flow rapidly around the cutter to quickly remove dirt in that area. It is something to do.

[Means for Solving the Problems] The gist of the configuration of the present invention is as follows: a container for mixing the mixing target in the container; a rotating shaft rotatably installed at the bottom of the container; In a mixer comprising an electric motor connected to the lower end of a shaft and a cutter disposed on the rotating shaft, a blade member that concentrates water flow around the rotating shaft and the cutter is detachably attached to the rotating shaft. This is a mixer that can be attached to.

The mixers to which the present invention is applied are all types in which a cutter is attached to a rotating shaft rising from the bottom of the container. Including those that can also be used as Juicers. The shape of the attached cutter does not matter. It can be said that the more dangerous something is, the more meaningful it is.

Of course, the shape of the container mentioned above does not matter. It will usually have a cylindrical shape.

The shape and number of the blade members can be freely determined as long as they can perform the above-mentioned action, that is, their rotation can concentrate the water flow around the rotating shaft and the cutter. More specifically, the water flow is a flow from above to below, a flow from below to above, or a flow from the periphery toward the axis.

The attachment structure for detachably attaching the blade member to the rotating shaft can be configured as follows, for example.

That is, a mounting ring is fixed to the rotating shaft, and the mounting ring is formed with a plurality of circumferential locking grooves and an upwardly opening entrance groove leading to these grooves, and the blade support is fixed to the locking groove. The leg portion has the same number of grooves and has locking protrusions on the inside thereof that lock with each of the locking grooves, and a knob portion stands up on the upper surface of the upper joint portion that connects all the leg portions. A blade member is attached to the outside of each of the leg parts to generate a water flow in the vertical direction as the rotating shaft rotates.

Furthermore, it is preferable that the mixer is provided with a temporary operation switch that temporarily operates the electric motor when the blade member is attached to the rotating shaft.

[Function] Since the present invention is configured as described above, the area around the cutter inside the mixer can be easily cleaned after use as described below.

After using the mixer, first attach the blade member to the rotating shaft, then pour water for washing into the container, turn on the switch for a suitable short period of time, rotate the electric motor, and rotate the rotating shaft.

In this way, due to the action of the blade member, a flow is generated in the washing water that concentrates around the rotating shaft and the cutter, and vegetable fiber pieces, fruit pieces, etc. adhering to this area are removed from the washing water. It flows out into the water and has a cleaning effect.

After turning off the switch and discarding the washing water, the washing work is completed. If necessary, the above cleaning operation can be repeated once or twice.

After this, remove the blade member.

If the blade member is configured to be removably attached to the rotating shaft via the attachment ring and the blade support member fixedly attached to the rotating shaft as described above, cleaning is performed as follows.

First, the blade support is lowered into the container by grasping the knob, and the locking protrusions formed on the inside of each leg are locked in the locking grooves of the attachment ring provided on the rotating shaft. The locking protrusion is inserted and locked into the locking groove through the entrance groove. Since the blade member is provided on the outside of the leg, in this case, it will be placed outside of the rotating shaft. Therefore, the blade member can be attached very easily.

After that, water for cleaning is poured into the container, and the switch is turned on for a suitable short period of time to rotate the electric motor and rotate the rotating shaft.

In this way, due to the action of the blade member, a flow is generated in the washing water that concentrates around the rotating shaft and the cutter, and vegetable fiber pieces, fruit pieces, etc. adhering to this area are removed by the washing water. It flows out into the water and provides a cleaning effect.

After turning off the switch, discarding the washing water, and pulling up the knob, the locking protrusion is released from the locking groove through the entrance groove, and the blade member can be removed.

The cleaning work is now complete.

If necessary, the cleaning operation of pouring water into the container again and operating the electric motor to rotate the blade member can be repeated before removing the blade member.

In the above-mentioned cleaning operation, if the mixer is provided with a temporary operation switch, by using the switch, the blade member can be rotated for a fixed short period of time with a single touch.
