Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for manufacturing juice,

The present invention relates to the field of making fresh juices from foods such as fruits and / or vegetables.

More specifically, the present invention relates to an appliance for exclusive use in the manufacture of juices, as described above, which enables an improved treatment of food while better preserving the organic properties of the obtained juice.

In the above-mentioned field, a large number of household appliances already dedicated to the manufacture of fruit or vegetable juices or to be non-dedicated are known.

The simplest of these is comprised of a motor-driven citrus press, whose compression head is integral with the electric motor shaft, which is rotated when the user manually places the food to be squeezed onto the compression head. These citrus presses have the disadvantage that the user has to manually actuate the device, the compression head directly, which creates a risk of contact between the user and the device drive. Also, its use is clearly not user friendly in that continuous pressure is required on the press head due to the food to be pressed.

As a result, as the squeezing proceeds, the flesh is accumulated on the squeeze head and around the squeeze head and inserted into the juice filtration pore to prevent it. In addition, another juice-producing household appliance such as a centrifugal separator which does not require the manual operation of the user for the food to be pressed in order to carry out the juice extracting operation is also known. These centrifuges operate by centrifugal separation of the food inside the vessel, as the name suggests, and the juice is extracted by the centrifugal force applied to the food. These devices are high performance with very fast juice output. However, the quality of the juice produced is affected by very serious contact between the juice and the air inside the centrifuge vessel, which greatly impairs the organic quality of the juice as it promotes a very rapid oxidation of the juice.

A state of the art appliance for juice production which has a screw press and is capable of separating and extracting the pressed residue of juice and juice is finally known. Specific embodiments of such a device are disclosed in Patent Documents 1 and 2. [

These state-of-the-art devices are satisfactory and high performance as regards the quality of the juice being squeezed and the juices obtained. However, none of these devices are capable of satisfactory drainage of pulp and other press residues. In practice, these residues are stored in a pressurized container, which makes it difficult to clean the equipment, or is discharged through a discharge port separate from the discharge port for the juice. On the other hand, since there are two separated outlets for juice and residues, they are unsatisfactory in appearance and the cleaning efficiency is not practical and the flesh is accumulated in the grooves provided at the outlet for exclusive use of residues.

On the other hand, another problem of these devices is that juice can not be stored discontinuously, for example, in a fractionated manner for each glass cup.

Therefore, the household appliance according to the present invention is advantageous in that the pressed residue under the working container can be directly discharged by gravity. This solves the problem associated with the presence of the second outlet simply and economically by means of a squeeze residue reservoir inside the device known from the prior art. For example, by merely placing the recovery receptacle under the working container, the recovery of the residue is facilitated, and cleaning of the container is also very convenient for simply rinsing the container with clean water.

According to a first preferred aspect, the case has a reservoir for residues disposed below the second outlet. Such a reservoir is integrated into the case of the device and has the advantage that it does not take up more than the volume of the device itself. In addition, such an integrated reservoir protects the user from the point of leaking residues during crimping and facilitates recovery of the residue after further compression.

Preferably, the reservoir for the pressurized residue has a canister which can be removed from the case of the apparatus, which can be removed from the case of the apparatus at the front of the case of the apparatus and accessible by the user .

According to another feature of the present invention, the second outlet of the press residue has an orifice formed at the bottom of the work vessel around the base of the screw press.

Preferably, the household appliance of the present invention further comprises a residue discharge delay means provided at the second outlet.

Advantageously, said delay means is formed by narrowing a certain section of the second outlet conduit.

In a preferred first embodiment of the device according to the present invention, the delay means comprises a valve arranged to at least partially close the second outlet conduit.

In a second preferred embodiment, the retarding means may comprise a flexible member mounted on a part of the second outlet conduit.

According to another aspect of the present invention and a preferred feature of the present invention, the first outlet is made to store at least a portion of the juice produced upon compression.

In this form, it is advantageous for the first outlet to have a tab for dispensing the juice obtained from the pressed food, whilst advantageously having a means for preventing the drop from being mounted on the tab.

Finally, according to the present invention, for the purpose of facilitating the serving of the juice produced to the user, the household appliances according to the present invention are placed under the outlet for the juice, preferably on the front face of the appliance case, And a groove or cutting portion capable of placing a cost receptor under the outlet.

Various other features are disclosed in the following detailed description, taken in conjunction with the accompanying drawings, which illustrate, by way of non-limiting example, an implementation of the object of the present invention.

The household appliances for making juice according to the present invention are capable of satisfactory discharge of flesh and other pressed residues. On the other hand, the household appliance according to the present invention has the effect that juice can be stored discontinuously, for example, in a fractional manner for each glass cup.

The present invention proposes a new home appliance (1) for manufacturing juice from foods, especially fruits and / or vegetables.

Figures 1 and 2 show two preferred variant embodiments of the device 1 of the present invention.

First, with reference to Fig. 1, the household appliance 1 of the present invention has a case 2 on which a work container 3 can be assembled.

The case 2 includes a driving electric motor and an electronic device for controlling and controlling the motor in a known manner. The drive shaft M of the motor partially protrudes and extends on the surface of the fixing plate formed on the case for receiving and fixing the working container 3.

The working container 3 has on its top an open receptacle, such as a bowl as shown in Figures 1 and 2, and a lid 10, which can be secured to the top of the receptacle. The working vessel 3 has an opening 4 for the introduction of food and a first outlet 5 for juice extending substantially transversely to the base of the working vessel 3.

In the embodiment of Figures 1 and 2, the inflow opening 4 is comprised of a chute 4a for the food provided in the lid 10, the section of which is intended to allow food such as apples or oranges to pass through Is selected.

As shown in Figs. 1 and 2, in the interior of the working container 3, first of all, the driving shaft M of the electric motor included in the casing 2 of the device is rotationally coupled to the bottom of the working container 3 A food pressing element having a screw press (7) is provided.

This coupling can be effected in particular via a rotating member (not shown), which is hermetically fixed to the bottom of the working container 3 and is mounted on the drive shaft M of the electric motor at the outer surface of the bottom of the container, And a mail part for coupling with the screw press (7) on the inner surface of the working container (3).

As shown in Figs. 1 and 2, the screw press 7 is advantageously substantially ogival and has a net 7a suitable for crushing the food to be pressed on its outer surface by rotation.

In order to carry out the squeezing of the food product in cooperation with the screw press 7, the device according to the present invention is also provided with a filtration drum 8a, which is formed, for example, in the interior of the working container 3 by a filtration drum 8a, Means 8 for realizing the separation of the "dry" residue and the juice of the pressed food. It is advantageous to design the filtration drum 8a such that its inner diameter is substantially equal to the maximum outer diameter of the screw press lying on the fruit edge of the net 7a.

Thus, a continuous, high-performance pressing effect of the food to be pressed between the screw press 7 and the filtration drum 8a is obtained, and good separation of the juice and the dry residue is possible. When the food is squeezed between the screw press 7 and the filtration drum 8a, the juice is guided by the orifice provided for this purpose across the sidewall of the filtration drum 8a and then toward the first outlet 5, And the wall of the work vessel (3).

At the same time, the dry residue of the food is discharged from the bottom of the working container 3 by the second outlet 6 for the pressed residue of the processed food.

According to the present invention shown in Fig. 1, the second outlet 6 for the compressed residue is formed by gravity from the bottom of the working container 3 by the orifice 6a formed at the bottom of the working container 3 And communicates with a reservoir (2a) for receiving and storing the pressurized residue by means of a substantially vertical discharge conduit or discharge tube (9), said reservoir being connected to the case (2) of the device (1) Lt; / RTI >

In the preferred embodiment shown in Figure 1 the reservoir 2a is advantageously constituted by a cylinder 2b which can be removed from the case 2 of the machine and the cylinder 2b is connected to the cylinder 2b, (Not shown) provided in the case 2 and complementary to the tub 2b by a handle 2c integral with the tub 2b so that the tub 2b can be easily drawn out and inserted do.

In this modified embodiment, the reservoir for receiving the barrel 2b is located at a rear portion of the case 2 of the appliance, i.e., at a portion opposed to the first outlet 5 for juice to be produced.

Conversely, in the embodiment of Figure 2, the device 1 comprises a reservoir 2a 'for receiving and storing the pressurized residue placed in the front of the case 2, i. E. Directly below the first outlet 5 for juice. . In this embodiment, the reservoir 2a 'is formed of a removable cylinder 2b provided with an operation handle 2c' and accommodated in a reservoir (not shown) formed in the front portion of the case 2. [ As is known, in this configuration, the second outlet 6 for the pressurized residue communicates with the tube 9 ', which is embodied on top of the reservoir for receiving the barrel 2b' and which passes to the top of the barrel 2b ' An orifice 6a 'is provided on the bottom of the container 3.

According to the present invention, it is advantageous for the second outlet 6 to be equipped with delay means 11, 11 ', 11 "for delaying the discharge of the residue. The delay means 11, 11', 11" Is formed or received in the orifices 6a, 6a 'or in the tubes 9, 9'. The delay means 11, 11 ', 11 "can particularly improve the juice yield of the device 1. Different embodiments of suitable delay means 11, 11', 11" do.

3a-3c, the delay means 11 comprises a flexible member 14 mounted on a part 12 of the conduit 13 of the second outlet 6. [ The flexible member 14 forms, in part, a flexible shutter that closes the conduit 13. The flexible member 14 may be in the form of an insert, which is mounted inside the conduit 13 in particular. 3 (b), the flexible member 14 has a tenon 15 which is inserted into the receiving portion 16 of the side wall of the conduit 13. The flexible member 14 may be embodied, for example, of polyurethane and / or molded into the conduit 13. The delay means 11 is also formed by narrowing a certain section of the conduit 13 of the second outlet 6 at the position of the flexible member 14. The delay means 11 has a valve arranged in such a way as to at least partly close the conduit 13 of the second outlet 6. The conduit 13 is, for example, a substantially rectangular horizontal section defining a substantially rectangular retentate passage. Accordingly, the flexible member 14 serves as a valve for delaying the residue toward the reservoir 2a, 2a '.

According to the second embodiment shown in Figs. 4a to 4c, the delay means 11 'has a transverse member 18 provided in a portion 12' of the conduit 13 'of the second outlet 6. Since the transverse member 18 divides the conduit 13 'into two parts 17a and 17b, the residual squeeze interval is reduced and the outflow is delayed. Thus, the delay means 11 'is formed by narrowing a certain section of the conduit 13' of the second outlet 6 at the position of the transverse member 18.

According to the third embodiment shown in Figures 5A and 5B, the delay means 11 "can be configured to limit the section 12" of the conduit 13 "of the second outlet 6. , The portion 12 "forms an opening in the vertical section, which is substantially rectangular in horizontal section and trapezium (the large base of which is located above the conduit 13"). The retarding means 11'delay the conduit 13 of the second outlet 6 from the portion 12 "to the conduit 13 ' ").

According to another particularly advantageous feature of the inventive device 1, shown in Figures 1 and 2 and detailed in Figures 6a and 6b, the first outlet 5 of the squeeze juice in the working container is created And is advantageously provided with a juice dispensing tab (21) fitted with a drop preventing means (22).

In the specific example shown in the figure, the tab 21 is comprised of a tube 23 extending from the working vessel 3 and slightly inclined towards the base to facilitate the outflow of juice from the vessel 3 . Advantageously, the tube 23 is several centimeters in length, indeed at least 5 centimeters, and the inner diameter is at least 1 centimeter, preferably at least 2 centimeters.

The free end (24) of the tube (23) is fitted with a stopper forming a drop preventing means (22). In the illustrated embodiment, the stopper is formed into a capsule 25 that is inserted into the end 24 of the tube 23 and can be pivoted between the closed position (Fig. 6A) and the open position (Fig. 6B) do. The pivotability of the capsule 25 is controlled by the inner annular neck 26 on the annular pad 27 formed on the outer wall of the tube 23 at the free end 24 position . The capsule 25 has an orifice 28 for pouring juice and is closed at the closed position by the edge of the end 24 of the tube 23 and at the open position of the capsule 23, Communicates with an orifice or crenel formed at the edge of the end 24. Therefore, in the closed position of the capsule, the tube 23 is clogged and the juice produced by the compression of the food in the container 3 can not flow out. In the open position of the capsule, the capsule 25 and the tube 23, The juice can be flowed out by the respective orifices 28,

The household appliance 1 of the present invention is designed to place a consumer receptacle such as a glass cup 31 under the tab 21 following the juice under the first outlet 5 and more particularly below the tab 21 It is advantageous to provide a groove or cutout 30 provided in the front of the case 2 of the device.

Regardless of the specific embodiment of the crimping device 1 described above, the use of this device is obviously very user friendly and very simple.

It is sufficient to start up the apparatus by, for example, operating the control switch I of the electric motor of the apparatus. Then, the user inserts the food to be squeezed, such as apple or carrot, into the downward sloping surface 4a as a whole or as a piece, and pushes this into the inside of the working container 3 by the push rod (P).

With the action of the push rod P, the food is moved by the net 7a of the screw press which falls into the container 3 and crushes and squeezes these pieces against the filtration drum 8a. The juice of the food is passed through the pores of the filtration drum 8a and flows out toward the first outlet 5 of the container by the squeezing, and the juice is stored in the tube 23 at the first outlet 5 of the container And the capsule 25 is in the closed position. To retrieve the juice, the user simply pivots the capsule 25 to the open position so that the juice flows out into the receptacle, such as a glass cup, prepared before the tab 21.

At the same time, as it is squeezed, the dried residue of the pressed apple is discharged by the second outlet 6 in the bottom of the container 3 and the reservoir 2a. Once the reservoir is full, it is sufficient for the user to empty and wipe the reservoir.

Since various modifications may be made without departing from the scope of the present invention, the present invention is not limited to the disclosed and illustrated embodiments.
