KR20070067171A - Improved liquefier - Google Patents

Abstract

The invention relates to a standard-type liquefier which is equipped with an anti-drip system consisting of a T-shaped pipe closure mechanism. In addition, a series of anti-slip strips, which are disposed in the connecting gears between the power unit and the rotating elements, enable the device to be stopped suddenly without the inertia of such elements propelling same upwards. Unlike in other liquefiers, the grater disc is not joined to the power unit by means of a screw that passes through same, but instead by a screw that is welded at the lower part thereof. The push piston terminates in a concavity which, during use, receives the piece to be liquefied. Said piston can be replaced by a piston that reduces the feed hole.

Description

Juicer {IMPROVED LIQUEFIER}

As the name suggests, an anti-drip system, a rotary drive system disposed between a module including a grinding disk and a motor, and a grinding disk are attached to a holding module. System, a special structure of a push piston for liquefying vegetable pieces, a reducer having a hole for feeding the vegetable pieces into juice, a lid pressure seal body by a handle member, and a base of the machine The present invention relates to an improved juicer that is superior to the ones used so far in that it includes a rear cooling air outlet.

There are various types of juicers on the market, each of which varies depending on whether it is used for professional cooking or for home use.

What is proposed here is an improvement on existing types in view of the following disclosure.

One of the problems commonly raised by juicers is that the residue left on the filter or grinding disc must continually flow out slowly, and a few minutes must pass until it finally stops falling. From the droplets.

The use of shut-off cocks is not recommended because they must consist of several parts with increased risk of breakage and difficulty in cleaning, and furthermore, if the cock is closed in the process of using juicer, It may overflow from the device.

The juicer proposed here has an inverted L-shaped hollow tube, preferably of flexible material, at the end of the juice outlet faucet so that the juice flows inside and flows out from the opposite end of the hollow tube inserted into the discharge tube, When the juice is provided, the hollow tube is easily rotated so that the dropping end of the juice, facing the end inserted into the discharge tube, is directed upwards, so that the hollow tube acts as a reservoir to hold inside the juicer. The droplets can be collected, so that they do not fall out.

Another improved aspect of the invention proposed here is the coupling between a drive system or motor and a rotating body comprising a filter and a grinding disc.

Among other existing systems, one of the most successful is the integral coupling of the motor to the male rotary drum on its sides, which are formed with a series of diagonal grooves. These grooves inclined in the direction of motor rotation engage and engage shoulders provided on the male drum and provided on the grinding disc and the other arm drum supporting the filter.

The above side grooves are inclined in the rotational direction to make the rotation faster and to make the connection between one part and the other part closer.

However, when attempted as in the case here, this solution raises the problem that the juicer must come to a complete stop as required by the user or as a result of accidental opening of the lid. This is because in this situation, the inertia of the part where the grinding disc and the filter are seated causes it to induce a force to act outward.

The above mentioned problem is overcome by the present invention by including strips of silicon or other non-slip material that can withstand greater pressure in the case of sudden stops at the edges of beveled notches. Can be produced, so that greater friction can be prevented from lifting the part.

This grinding disc is also designed to provide better performance than in other juicers, so that the disc is attached to the rotor by screws through the through-holes or by other integral and indelible means.

The use of through-screws causes two problems, one of which is that the head of the screw considerably reduces the area of the grinder at the center, and the other part, when the parts of the machine are cleaned. Is necessary.

The juicer proposed here has a grinding disc, and a screw for fixing the grinding disc to the rotating body is welded to the lower side thereof, or attached by other means to ensure strong and permanent connection, so that the grinding disc is attached to this. It is suitably dedicated to the head of the screw, so that the entire area of the grinding disc can be used.

Another problem that usually arises in juicers is when fruits or vegetables are transported towards the grinding disc, because in normal practice it is usually due to the lid that seals the space where the filter and grinding disc rotate while providing holes. In the hole below the lower tubular extension, the juiced fruit or vegetable is fed by a hand operated push piston, pushed into the upper hole and pressed into the disc.

In general, the lower side of the push piston is generally flat or mostly slightly inclined in contact with the fruit or vegetable, and as a result the fruit of some size sometimes has no guide member when pressed flat against the rapidly rotating disk. Because of this, they move around in any form inside the tube, impinging on its side walls and causing considerable vibration.

The lower side of the piston proposed here has a subtle, preferably eccentric groove, so that when the fruit or vegetable is pressed against the grinding disc, it is lightly enclosed inside such groove so that it cannot escape from such pressure. And the force is applied at an angle formed by the grinding disc and the filter.

Despite the improvements introduced in the push pistons, since the supply holes are designed for fruit of considerable size, a series of vegetables, for example carrots, has proved difficult to liquefy due to their narrow and long shape, so they As a result of the rotation, as a result of the rotation they generate the vibrations mentioned above or even are moved to the outer edge of the grinding disc, as a result of which the device has to be turned off and open in order to repeat the feeding operation.

The juicer proposed here comprises a feed-hole reducer consisting of a truncated cone-shaped component, which is inserted into the hole and then pushed another appropriately sized push across its entire length. Smaller diameter holes are formed in which the piston is inserted.

Another object of the improved juicer of the present invention is to relate to the opening and closing member of the lid, which requires airtightness and at the same time allows easy opening operation. As disclosed in utility model U291323, outer handles can be made, which press the lid downwards against the container containing the filter as it is lifted, on the contrary the lid is released by lowering the upper handle.

This method causes problems of use because the handle is external. That is, an angle or corner that is difficult to clean is created, and furthermore, there is a risk of tipping over the jug containing the juice when lowering the handle with the lever under the filter to allow the levering action.

In order to overcome both problems, the object of the juicer of the present invention proposes a handle-shaped part separate from the juicer, which simplifies and facilitates cleaning. In order to satisfy the pressure-tight function, the above part is engaged by the claw-like ends with two T-shaped heads which protrude from the casing and extend inwardly.

When the handle member engages the heads and pushes the handle member down, its actual geometry attempts to lift the heads. The heads resist upward movement due to their movement or springs or elastic members that pull them in opposite directions. Thereby enough pressure is generated to achieve tightness of the upper lid of the juicer.

When the handle member is in the horizontal position of use, it is fully integrated into the machine geometry. This improves cleaning workability and prevents the risk of it and other accidents.

As with the others, the object of the juicer of the present invention is provided on its back with a bucket for collecting pulp and debris from the juice process.

The special design of the bin with its groove on its inner side allows the cooling air of the motor to be discharged from the back side of the body of the juicer. Thus, when the bins are in place, the ventilation grilles are invisible, thereby protecting the motor from the ingress of dust or small substances that could damage the operation of the motor.

The design of the bins directs hot air towards the base of the machine.

Although much of what is set forth herein is already included in the prior art, the present invention has been completed and described by incorporating the present invention in order to more clearly understand the present invention.

As already disclosed, the juicer comprises a fall protection means consisting of a single piece of single material inserted into the nipple and adjustable at the inlet of the nipple to prevent leakage.

This fall arrest means is inverted " L " and one of its ends is attached to the nipple and the opposite end is open.

At the location of use the juice flows along the interior of this inverse “L” or elbow.

After use, if you want to stop the liquid from dripping from the device, turn the entire fall prevention means. The end of the juice outlet is then set to a higher position with respect to the nipple, so that a few drops of leaking juice act as a reservoir to allow the juice to leak if not overflowed due to excess production. Stored in the means. This overflow protection structure is intended to ensure that the overflow of the appliance is prevented.

In order to facilitate the rotational operation of the fall prevention means, it is desirable to provide tabs or shoulders for better grip by the user.

The configuration of the juice with the motor, ie the rotation between the grinding disc, the filter and the support, is transmitted by the combination of the two male and female drums. Here, the male drum has side grooves which are integrated in the motor and inclined in the rotational direction of the motor. The arm drum encloses the male drum and has an internal relief on its inner surface to engage the grooves in a faster rotation and stronger bond between the two drums.

 The lower drum has strips of silicon or other non-slip material on at least one side on the grooved side to absorb the pressure when the motor is suddenly stopped, even if the motor suddenly stops. Is maintained by the upper drum, thereby preventing the inertia of the upper drum from causing the upper drum to detach.

Grinding discs used in juicers are characterized in that the screws which fix the discs to the rotating body are welded to the bottom of the disc or otherwise attached in other ways to ensure a firm and lasting bond. This reduces the number of parts that need to be removed or reassessed when cleaning the instrument, and furthermore makes the entire area of the grinding disc with additional cutting elements available, making juices more efficient and faster. .

The piston that exerts pressure on the juiced object, particularly at its bottom, preferably has an eccentric groove to catch and trap the juiced fruit or vegetable so that it does not escape from the pressure exerted by the push piston and is out of control. It is characterized by preventing the unnecessary vibration to hit the wall of the tube while traveling around.

In the case of smaller or longer elongated shapes, as in the case of carrots, special truncated cone-shaped pistons are designed. This piston is mounted in the supply hole, and in effect acts as a reducing tube. This is because the piston is traversed by smaller diameter through-holes operating along its entire length, allowing another push piston of a size corresponding to this new reduced hole to be inserted.

For airtightness of the entire assembly, the lid is designed to include a handle-like member in geometry. When fully engaged with the heads protruding from the body of the casing, the handle member acts as a lever that delivers sufficient pressure to keep the lid closed during the juice operation.

This bucket-handle shaped member has claw-like ends that engage in engagement with "T" shaped shoulders or heads protruding from the casing of the juicer in a vertical position.

When combined with these heads the position of the handle member moves horizontally, its geometry provides pressure to the heads, thereby providing resistance to the action of elastic means.

To open the lid, move the handle member to a vertical position and remove it from the heads.

The purpose of the juicer of the present invention is to provide juice and a trash can on the back to collect all the residue left. A feature of the bin is that its inner surface is provided with a groove extending down to its base to form a horseshoe shape, whereby the cooling grille of the appliance can be located on the back side of the motor body. Thus, when the wastebasket is in place, the grill is invisible and no dust or other foreign matter can enter it, which in turn prevents damage to the motor.

The special shape of the bins allows the cooling air to flow to the base of the device.

[Brief Description of Drawings]

The drawings show graphically the various components mentioned above, and the drawings shown herein do not show more than one method and are therefore only one example of implementing the technical solutions disclosed in the present invention.

FIG. 6 shows a push piston that performs the function of a supply hole reduction tube 16 and a general small push piston 17 when inserted into the reduction tube.

FIG. 7 shows the handle member 18 separated from the body of the juicer, where the “T” shaped heads 20 act as hinges and claw-shaped ends 19 of the handle member. Thereby, the handle member can apply sufficient pressure to the lid so that the lid 21 remains airtight as long as the pivoting and juiced operation is continued.

Figure 8 shows the back of the juicer after removal of the trash can. Here, the ventilation opening 22 can be seen.

9 shows a trash can 23 with a horseshoe-shaped base 24 and a groove 25 machined on the inner surface of the trash can for venting cooling air from the ventilation grille 22 located at the rear of the appliance.

The present invention is an improved juicer as described in the previous section. The hollow inverted " L " dropping piece 1 is inserted at the end of the discharge faucet in such a way that the liquid can normally flow out when the dropping piece is in use. Then, after the appliance is used, to prevent the rest of the juice from leaking out, simply turning the above dropping prevention piece sets the end 6 at which the juice flows upward. The nozzle is thereby higher than the end of the nipple, so the dropping piece stores leaks by acting as a reservoir for the rest of the juice that is still there.

Moreover, the drive action between the motor and the rotating body incorporating liquefied components takes place through the connection of two drums, namely the male drum 8 and the arm drum 9. Here, the male drum 8 is provided with a series of inclined grooves 10 in the rotational direction, and the arm drum 9 is provided with shoulders 11 arranged on the inner surface thereof in alignment with the inclined grooves formed in the male drum.

The inclination of the inclined grooves 10 and the shoulders 11 in the rotational direction makes the speed faster and the connection between the two members closer.

In order to prevent the upper drum from being forced upward by the inertia effect and the inclination of the inclined grooves when the motor stops, a strip of silicon or other non-slip material 12 is inserted into the side of the male drum inclined grooves. Absorbs shock in case of sudden stop. Thus, the arm drum is prevented from slipping due to the inertial effect because of the friction created and is in place.

Another technical solution realized by the present invention is that the grinding disc has screws attached to the bottom of the disc by welding or in other rigid and stable manner. This facilitates the workability of separation and reassembly for cleaning and also secures a larger grinding area since it is not necessary to set the head of the fixing screw 13 near the center of the grinding disk.

The push piston 14 of the fruit and vegetable is particularly recessed in its bottom part to form an oval recess groove 15 so that the pressed fruit or vegetable is caught in the recess groove, whereby the piston It is free to move away from the pressure and to prevent unwanted shocks and vibrations.

However, the piston design described above does not prevent juiced pieces such as carrots, for example, from becoming difficult to liquefy due to the diameter of the supply hole to be applied to their particular shape or larger sized fruit. Because they continue to deviate from the push piston.

In order to overcome this problem, the juicer is provided with a supply hole reducing tube 16 is configured in the form of a trunk (trunk) mounted to the supply hole. In this reduction tube 16, a smaller diameter hole is made across its entire length, which is used by inserting a push piston 17 of another suitable size.

In addition, one of the improvements of the juicer relates to the tightness of the lid 12 covering the body since the lid is required to have an appropriate pressure to prevent unwanted liquid leakage or movement during juiced operations.

In this case, the pressure is preferably achieved by an elastic piece or spring which clamps the braces terminated in the “T” head 20 protruding to the top of the juicer casing.

These "T" shaped heads act as hinges for the handle member 18 and are engaged with them in a vertical position by the toe-shaped ends 19 of the handle member.

When the handle member is lowered to the horizontal position, it pulls the head upwards because of its geometry, which tightens the elastic piece or the spring, which is the downward direction that the handle member 18 transmits to the lid when in the horizontal position. Creates pressure to the furnace. Also, because of the geometry of the lid and handle member, the handle member is integrated into the lid.

To proceed with the opening of the lid, simply lift the handle member to a vertical position and separate the handle member from the "T" heads. Then, the handle member is easily separated for free cleaning.

Another feature of the juicer according to the present invention is the ventilation grille 22 located at the top of the body, where a waste bin is located behind the body, so that the grill is invisible. This prevents dust and other substances from entering the grill and causing damage or defects.

The position of this grill is possible due to the design of the wastebasket 23 which is provided with a groove 25 in the inner surface to exhaust the air and redirect the air toward the base of the device.
