Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a mixer that creates juice by putting fruit or milk in a cup and crushing and stirring it with a cutter rotating inside the cup. This allows safe grinding and stirring of hot ingredients such as vegetables and meat.

An embodiment of the present invention will be described below with reference to the accompanying drawings.

In the figure, reference numeral 1 denotes an electric motor, which is attached to the main body 2 with screws 3.

Reference numeral 4 designates the shaft of the electric motor 1, and a rotation transmission joint 5 is fixed to the upper part of the shaft, and is fitted with the rotation transmission joint 6 to transmit the rotation of the electric motor 1 to the cutter 7.degree. 8.

Reference numeral 9 denotes a main shaft, a rotation transmission joint 6 is fixed to its lower part, and a cutter 7.8 is fixed to its upper part together with a sleeve 10.

Reference numeral 11 is a tipped stand, and in the center there is an insert metal fitting 12.
are integrally molded, and a main bearing 13 is press-fitted into the insert fitting 12 to pivotally support the main shaft 9.

Numeral 14 is a tip whose lower part is cylindrical and suddenly widens slightly above the cutter 7, and is screwed onto the tip base 11 via a packing 15.

Reference numeral 16 denotes a tip lid that covers the upper opening of the tip 14, 17 a back plate that covers the lower opening of the main body 2, 18 a leg, and 19 a switch.

Reference numerals 20 and 21 are an outer lid and an inner lid that constitute the top lid 16.

A plurality of ribs 20a are provided on the outer surface of the outer cover 20 that covers the opening of the tip 14, and the inner cover 21, which is removably installed in the center of the outer cover 20, has an exhaust hole at a part that protrudes outside the outer cover 20. 21a is located above the rib 20a, and an eave-shaped collar portion 21b is formed.

Next, the operation will be explained.

First, when making juice, connect the top 11 to the main body 2 with a bayonet, put fruit, milk, etc. into the top 14, attach the lids 20 and 21, and operate the switch 19 to turn the electric motor 1 on.
When the cutter 7.8 is rotated, the fruit and milk are crushed and stirred to produce juice.

On the other hand, when grinding and stirring hot ingredients such as boiled vegetables and broth, put the ingredients into the pot 14 and operate with the pot lid 16 attached, and steam will be discharged from the gap between the outer lid 20 and the inner lid 21. 1 (arrow A), hot materials can be crushed and stirred without any problems in the same way as the juice described above.

In the conventional mixer, as shown in FIG.
, 23 do not have holes for discharging steam, so when hot materials are crushed or stirred, the top lids 22 and 23 float up due to the pressure of the steam inside the top.

In addition, conventionally, holes of the size of air vents provided in some pot lids may not cause problems at room temperature, but when hot materials are crushed or stirred, steam cannot be sufficiently discharged, causing problems similar to those described above. A phenomenon occurs.

At this time, the pot lid comes off from the pot and the hot material inside the pot spills out into the surrounding area, which is very dangerous (depending on the temperature and amount of material, up to 30 crrL around the pot).

In order to prevent the top lid from floating up and the material from spewing out, it is effective to provide a sufficiently large hole in the top lid to vent the steam inside the top.

However, in this method, hot steam is directly discharged from the inside of the pot to the outside, so if a hot material of approximately 100° C. is crushed or stirred, steam of approximately 80° C. or higher is discharged, which poses a risk of burns.

Therefore, a hole was made in the B part of the conventional lid (see Figure 3).
At the same time as discharging steam, the diameter of the lid 23 is increased.

At this time, the steam flows out along the arrow E, so by increasing the diameter of the lid 23, the temperature of the steam decreases when it exits to the outside.

However, in this method, the discharged steam is heated to 60°C.
In order to lower the temperature to ~70°C, it has been found from experimental results that it is necessary to make the diameter approximately the same as the size of the lid 22 (indicated by the broken line in Figure 3).

If this continues, the lid will become very inconvenient to use.

However, in the case of this embodiment, the exhaust hole 2 of the inner cover 21
The steam discharged from 1a is separated by the ribs 20a of the outer lid 20 and discharged to the outside, and even when grinding and stirring hot materials of about 100°C, the steam discharged is cooled to below about 60°C. .

In addition, since the steam is discharged evenly from the entire circumference of the inner lid 21,
The speed at which the steam is discharged is also small, so there is no risk of burns.

Further, the cooling of the steam is large, and there is no need to make the diameter of the inner lid 21 as large as shown in FIG. 3, making it easy to use.

As described above, the present invention can provide a highly safe and easy-to-use mixer that does not eject hot materials or steam even when pulverizing or stirring hot materials by improving the shape of the top lid. And its value is very dog.

Claims (1)

[Claims] 1. A main body containing a built-in electric motor, a pot placed on the main body, a pot lid that covers the upper opening of the pot, and a cutter that is driven by the electric motor and rotates within the pot to crush fruits, vegetables, etc. The pot lid is a mixer with an exhaust hole that exhausts air from inside the pot and multiple ribs that separate the exhausted air.
