Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a mixer that puts fruits and milk in a cup and crushes them with a cutter rotating inside the cup to create a concentrated juice.In particular, by improving the shape of the cup lid, This allows for safe grinding of boiled vegetables, meat, and other hot ingredients, and also ensures that there is no noise during operation even if holes are provided in the cup lid.

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 denotes the shaft of the electric motor 1. A rotation transmission joint 5 is fixed to the upper part of the shaft, and the rotation transmission joint 6 and the rotation transmission joint 6 are connected to the shaft of the electric motor 1.
The rotation of the cutters 7 and 8 is transmitted to the cutters 7 and 8.

Reference numeral 9 denotes a main shaft, a rotation transmission joint 6 is fixed to its lower part, and cutters 7 and 8 are fixed together with a sleeve 10 to its upper part.

11 is a cup 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 metal fitting l2 to support the main shaft 9.

A cup 14 has a cylindrical lower part and is suddenly widened slightly above the cutter 7, and is screwed onto the cup stand 11 via a packing 15.

16 is a cup lid that covers the upper opening of the cup 14, 17 is a back plate that covers the lower entrance of the main body 2, 18 is a leg, and 13 is a switch.

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

Annular ribs 20a and 20b are provided on the outer surface of the outer lid 20 that covers the opening of the cup 14, and an inner lid 21 that is removably installed in the center of the outer lid 20 has ribs that protrude outside the outer lid 20. A hole 21a is formed at this location, and an eave-shaped flange 21b is formed above the inner rib 20a. That is, a cavity A is formed between the outer cover 20 and the inner cover 21, that is, between the ribs 20a, 20b and the collar 21b. Note that the rib 20a may be a complete ring as shown in FIG. 2, or it may be provided only at a portion facing the hole 21a and arranged in an annular shape as a whole, as shown in FIG. , the rib 20a is close to the hole 21a. Next, the operation will be explained.

First, when making juice, connect the cup stand 11 to the main body 2 by bayonet, put fruit, milk, etc. into the cup 14, attach the lids 20, 21, and operate the switch 19 to move the electric motor 1.
When the cutters 7 and 8 rotate, the fruit and milk are crushed and crushed to produce juice. On the other hand, when grinding and thickening hot ingredients such as boiled vegetables and broth, put the ingredients into the cup 14, attach the cup lid 16, and operate. ~ Steam is discharged from the gap B between the outer lid 20 and the inner lid 21. "(
(It flows out at arrow C in Figure 1) ``Similar to juice, hot materials can be crushed and transported over the ocean without any problems.

With conventional mixers, ``the lid of the cup does not have holes to allow steam to escape, so hot ingredients are crushed.'' When the mixer is used, the lid of the cup floats up due to the pressure of the steam inside the cup.

Additionally, the holes in some conventional cup lids, which are large enough to allow air to escape, do not allow enough steam to escape when hot materials are crushed, resulting in similar results. At this time, it is extremely dangerous as the cup lid comes off from the cup and the hot material inside the cup spills out into the surrounding area. It is effective to exhaust the steam inside the cup.However, with this method, the hot steam is directly discharged from the inside of the cup to the outside. Because of this, there is a risk of burns, etc. Also, the sound of materials being crushed and sardine worshiping leaks directly to the outside and is noisy.In addition, to prevent the lid from floating, the lid is completely mechanically attached to the cup. However, this method is dangerous because if there is a slight gap between the cup and the lid, or between the outer ring and the inner lid, steam or hot material will spew out from that area.However, it is dangerous. ~In the case of the embodiment, "The steam inside the cup is discharged from the hole 21a of the inner lid 21, beyond the rib 2Qa of the outer lid 20, and out through the gap B (arrow C in FIG. 1). The inner lid 21 does not float up, and hot material does not splash out around the cup 14.

At the same time, ``Steam accumulates once in cavity A and then is discharged to the outside, so even when approximately 10,000 hot materials are crushed with a light punch, the steam discharged is cooled to below approximately 60oC, and the steam is discharged from the gap. Since the liquid is ejected evenly from B to all stations, the ejection speed is low and there is no danger of burns.Furthermore, a rib 202 is provided in the cavity A near the hole 21a of the cup lid, which does not completely close the cavity A. Therefore, when the material is crushed and entrained, the noise and steam generated in the cup 14 are expanded and contracted by the cavity A, the ribs 28a, and the holes 21a before exiting to the outside, reducing the noise and reducing the steam. It also has the effect of being cooled down to a very low temperature.

As described above, the present invention improves the shape of the cup lid to ensure high safety as there is no ejection of hot materials or steam even when hot materials are pulverized or crushed. It is possible to provide a mixer that makes low noise when mixing, and its value is extremely high.
