Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a juicer, which processes a material to be cooked by cutting and pulverizing it with a cutter and squeezing it with a squeezing section of a rotating body. The present invention relates to a filter that is fitted into a juice outlet provided in a cooking case that surrounds a rotating body with a small gap therebetween, and that filters out the juice of a cooking material.

[Conventional technology]

In the conventional juicer of this kind, as shown in FIG. 7, one of the rotary bodies 2 rotates around a vertical rotation axis 1 and has a substantially cylindrical lower part and an enlarged upper part in the shape of a funnel.
The material to be cooked is cut and crushed by a plate-shaped cutter 3 provided on the surface, and this cut and crushed material is squeezed by a spiral squeezing part 4 formed on the circumferential surface of the rotating body 2. In order to filter the juice of the squeezed material and make it flow out into the juice outflow chamber 5, a juice outflow lower is provided in the substantially cylindrical lower part of the cooking case 6 that surrounds the rotating body 2 with a small gap therebetween. As shown in FIG. 8, there is a screen body 9 made of a metal plate that is flush with the inner surface of the cooking case 6 and has a large number of small holes 8 through which the juice of the ingredients to be cooked is filtered; A structure is adopted in which a filter 11 having a filter frame 10 in which the periphery of the screen body 9 is embedded is fitted and attached to the juice outflow lower. In order to reliably fix and attach the filter 11 to the juice outflow lower, engaging steps 12 are provided on both side edges and the lower edge of the inner surface of the outflow lower, and an engaging protrusion 13 is provided on the upper edge. Further, an engagement piece 14 having a cross-section shape is provided protruding from the upper edge of the filter frame 10, and the filter frame 10 is attached to the engagement protrusion 13 from the inner surface of the cooking case 6.
A structure is adopted in which the engaging piece portions 14 of the filter frame 10 are engaged with each other, and both side edges and the lower edge of the filter frame 10 are fitted into the engaging stepped portions 12 of the cooking case 6, respectively.

(Problems to be Solved by the Invention) In the above conventional structure, the juice outflow lower is formed only at the bottom of the approximately cylindrical cooking case 6, so the area of the juice outflow lower is small, and therefore the material to be cooked is The squeezing efficiency is low, and since a filter frame with a small area must be installed from the inside of the cooking case 6 to the lower portion of the juice outflow lower part, there is a problem that the operability of attaching and detaching the filter 11 is poor.

Therefore, it may be possible to expand the juice outlet to the top of the approximately funnel-shaped cooking case, but in this case, the filter fitted to the juice outlet may be formed to be flush with the inner surface of the cooking case. However, if the screen body of this filter is formed by squeezing, there is a problem in that the cost becomes high.

An object of the present invention is to increase the efficiency of squeezing the material to be cooked by opening the juice outlet from near the lower edge to near the upper edge of the cooking case to increase the area of this outlet and correspondingly enlarge the filter. It is an object of the present invention to provide a juicer capable of improving the performance of the filter and improving the operability of attaching and detaching the filter at a low cost by molding the screen body of the filter by bending.

0, and in this state, the cooking case 32 and the support case 25 are connected to the case fitting part 22 of the lid body 70 and the container body 21.
It is held between the

When the electric motor is driven by a switch operation, the rotating body 54 is rotated. In this state, the material to be cooked is introduced from the input lower 3 and is pressed by the push rod 74 against the cutter 66 of the rotating body 54.

The material to be cooked is cut and pulverized by the cutting blade of the cutter 66, and sent out toward the outer circumference of the cutter 66, and then passed through the rotating body 54.
is sequentially fed into the feeding guide portion 33 of the cooking case 32 from the periphery of the rotating body 54 to the squeezing portion 65 of the rotating body 54 and the cooking case 32.
The material to be cooked fed between the inner circumferential surface of the i! ! Juice outflow chamber 28
The juice flows into the juice container 30 from the juice outlet 29 of the juice outflow chamber 28. In addition, the squeezed residue of the material to be cooked is sent to the lower part of the cooking chamber 55,
The dregs are stored in the dregs storage section 26 from the dregs discharge port of the cooking case 32.

At this time, the juice outlet 37 into which the filter 38 is fitted opens from the bottom of the cooking case 32 to near the upper edge,
Since the area is large, the juice can be efficiently flowed out, and since the juice and the cut cooking material are not mixedly accumulated in the upper part of the rotating body 54, the The feeding of cut pieces of material becomes smooth, and since juice is not mixed in, the pressure in the cooking chamber 55 increases and the squeezing efficiency is improved.

Furthermore, even if the juice separated from the cooking material cut by the cutter 66 is scattered due to centrifugal force, the lip portion 69 of the seal packing 68 is pressed against the inner surface of the lid body 70, and the lip portion 69 of the seal backing 68 is The increase in internal pressure enhances the sealing effect, and the juice does not leak from the lid 70.

Since the screen body 45 is etched to form a mesh shape including small holes 43 through which the juice is filtered, it is also possible to change the mesh pattern of each screen portion 44 of the screen body 45.

For example, if the mesh shape of each screen part 44 is the same, the material to be cooked squeezed by the squeezing part 65 of the rotating body 54 will be sent downward along the inner surface of the cooking case 32, but the material to be cooked will be fed downward along the inner surface of the cooking case 32. (Since the pressure inside the cooking chamber 55 increases, the amount of pulp waste of the material flowing out from the screen portion 44 increases downwardly.

Therefore, the upper screen portion 44 may be made coarser and the lower screen portion 44 may be made finer. For example, the size of the small holes 43 in the upper screen portion 44 may be increased, and the small holes 43 in the lower screen portion 44 may be made smaller. Upper screen part 4
4, or by increasing the number of small holes 43 in the upper screen part 44 and decreasing the number of small holes 43 in the lower screen part 44, the unit of the upper screen part 44 is increased. If you increase the opening area per area,
It is possible to reduce the pulp residue of the material to be cooked contained in the juice fraction without changing the squeezing efficiency. in this way,
By changing the mesh shape of each screen portion 44, it is possible to change the quality of the juice, and it is possible to extract juice that is easier to drink.

〔Effect of the invention〕

According to the present invention, the juice outlet is formed from the vicinity of the lower edge to the vicinity of the upper edge of the cooking case, which has a substantially cylindrical lower part and an enlarged upper part to form a substantially funnel shape, and the juice outlet is formed from the vicinity of the lower edge to the vicinity of the upper edge. Since the area of the filter that is fitted into the outlet from the inner surface of the cooking case and filters the juice of the material to be cooked is correspondingly increased, the efficiency of squeezing the material during cooking can be improved, and the filter It is possible to improve the operability of attaching and detaching the filter to the cooking case, and the screen body of the filter is bent between the left and right notches on both sides formed between the plurality of screen parts, and the screen body of the filter is bent between the notches on both sides and the left and right sides formed between the plurality of screen parts, and the screen body of the filter is Since the filter is bent so as to form substantially the same plane, the filter can be easily molded and can be obtained at low cost.
