Description

This invention relates to a device for the production of beverages by infusion or extraction of the product contained in the container.

In particular, it can be used to make coffee from ground coffee beans packed in a container.

Such containers, as a rule, are made by joining two sheets of filter paper forming the inner space of the packaging for ground coffee.

Various machines are known for making hot drinks from ground products.

In particular, document WO-A-00/38558 describes an extraction chamber for an automatic machine for preparing hot drinks for receiving containers or pre-dosed tablets of ground coffee.

The camera consists of two parts moving in the horizontal plane, made with the ability to move away or move closer to each other, and the movement of both parts is interconnected.

A machine equipped in this way generally satisfies the set requirements, but makes it necessary to move the two components of the chamber.

Therefore, in this machine, it is necessary to provide a sufficiently powerful drive and a relatively sophisticated power transmission system necessary for synchronizing movements.

At the same time, a beverage production installation is known from document FR-A2.745.995, in which the infusion chamber consists of two half-forms, one carries the surface of the installation body, the other is fixed to the surface of the boiler, and these two surfaces face each other.

The infusion chamber is formed when the two halves are next to each other.

The camera is connected by moving one of the half-forms.

The presented installation makes it necessary for the coordinated operation of various locking elements to ensure that the container is held at the time of loading and during its entry into the infusion chamber.

The mobility of the locking elements is equally necessary to guarantee the removal of used portions.

The internal device described above requires the use of various locking elements and a device for removing containers.

From document US 5520093, a coffee machine with containers in the form of a tape is known in which the infusion chamber comprises a part having the possibility of rotation and movement by means of a drive shaft. In addition to the overly complex system of loading and removing containers, this device is unnecessarily complex both in terms of design and in terms of actuation, which involves sealing the chamber using a cam system.

EP 1153561 describes a coffee maker with a capsule with a movable lid for opening or closing the infusion chamber. A sophisticated capsule pressing system is also provided.

To actuate the infusion chamber, the means for moving the chamber parts must be massive and have a complex structure, in particular, to ensure tightness in the closed position. It should be borne in mind that an espresso machine produces hot water often under a pressure of about 15 bar.

The basis of this invention is the task of developing a device to eliminate the disadvantages of the above devices.

It is an advanced device for making drinks.

The first advantage of the invention is that it allows opening and locking of the infusion chamber, as well as loading and unloading of containers by fewer movements and, in particular, by combined rotational and translational movement of only one of the constituent parts of the chamber.

Another advantage of the invention according to a preferred embodiment is the use of only one drive device for providing rotational and translational movements, which ensures reliable synchronization at the lowest cost.

According to a preferred embodiment of the invention, the device is actuated by the user by turning the lever.

Thus, the claimed device is close to a standard coffee maker, which is a filter holder with a handle that provides the extraction phases of the drink automatically.

An additional locking device is designed to provide or improve the tightness of the chamber in the extraction position.

The present invention relates to a device for preparing drinks by brewing from a product contained in a container, including a brewing chamber for receiving a container and consisting of two parts configured to move closer together and apart to close or open the brewing chamber, one of the parts made rotating for pressing the container in the aforementioned part, and with the possibility of translational movement, for opening or closing the infusion chamber, and characterized the fact that it contains additional locking means when closing the two parts of the infusion chamber.

In accordance with a preferred embodiment of the invention, the claimed device is characterized by the following features.

Additional locking means in the device are means of longitudinal movement of the part that does not have the possibility of rotation.

The moving means are formed by a hydraulic cylinder.

The hydraulic cylinder is powered by a boiler feeding the infusion chamber.

The chamber of the hydraulic cylinder is formed between the surface of the boiler containing the power supply with hot water, and a movable element rigidly connected to the non-rotating part of the infusion chamber.

The device comprises an elastic, impermeable membrane between the aforementioned surface and the aforementioned movable element, for hermetically closing the chamber of the hydraulic cylinder.

The movable element comprises a feed channel of the infusion chamber formed between the cylinder chamber and a sprinkler provided on the non-rotating part of the infusion chamber.

The feed channel has a valve designed to open the feed channel at a pressure higher than the working pressure of the hydraulic cylinder.

The device contains a return spring of the movable element of the hydraulic cylinder.

The device contains one drive means, common for bringing into rotation and for translational movement of the movable part of the infusion chamber.

The driving means is made in the form of a cam having a first external abutment surface acting on a slider attached to the movable part of the infusion chamber and a second external abutment surface acting on the end of the rocker arm connected to the movable part of the infusion chamber.

The cam is driven by a lever.

The common driving means comprises a rotating drive shaft connected to the movable part of the infusion chamber by at least one connecting rod mounted rotatably between the aforementioned drive shaft and the aforementioned movable part.

The device comprises a slider rigidly connected with the movable part of the camera during its translational movement and with respect to which it can rotate.

The device has guides for the slider.

The shaft is driven by a lever.

The device contains guiding means for the container.

The guide means for the container include a guide with at least one groove for receiving the peripheral part of the container.

The guides are mounted movably, with the ability to follow the movement of the convergence or divergence of parts of the infusion chamber.

The movable part of the infusion chamber ensures that its front surface is parallel to the front surface of the fixed part, before their connection, during the closing phase of the infusion chamber.

The invention is further explained in the description of the variants of its implementation with reference to the accompanying figures of the drawings, given as examples and not limiting embodiments of the invention.

The device according to the invention, in particular those shown in FIGS. 6 and 7, usually comprises a boiler 9 supplying the infusion chamber 1 with hot water for extraction from the substance contained in the container, in particular from ground coffee.

As shown in FIG. 2, the water circulation system 10 extends on the side of the device and comprises a hot water supply part 11 to the infusion chamber 1 and a drain part 12 with access to the tray 13, draining the beverage to the funnel 14, directing the beverage to the user vessel.

As shown in figures 1-14, the end part of the system can be made in the form of a traditional filter holder containing a handle made in the form of a lever 15, and a part forming a funnel 14.

As containers with the product can be used containers of known types on the market.

It is desirable, but not necessary, to use containers 2 having a strictly flat and hard periphery, ensuring the preservation of the shape of the container.

The infusion chamber 1 consists of two parts 3.4, which can converge to close the chamber 1, as shown in figure 2, or diverge to open it, as shown in figure 1.

As will be shown below, part 3 of the camera is made with the possibility of movement for approaching or moving away from another part 4.

At the same time, part 3 of the camera is made with the possibility of rotation with a limited stroke, to switch between different positions in the operating mode.

It is preferable to use the same drive to provide movement and rotation of the movable part 3 of the camera.

In the following, two embodiments of the drive will be described.

The first embodiment will be described with reference to figures 1-14.

Figure 2 as an example shows the position of the axis 8 of rotation of the movable part 3 of the infusion chamber and axis 7 of its movement.

Below we will consider an example of a horizontal extraction machine (in which the container is located strictly vertically and receives hot water in a strictly horizontal line).

However, other orientation options are possible without departing from the scope of the invention.

A single drive may consist of a rotating cam 16 having an outer surface consisting of two sections.

The first portion of the outer surface 17 of the cam 16 provides a cam action on the slider capable of transmitting the translational movement of the movable part 3 of the infusion chamber.

The second outer surface of the cam 16, designated as surface 18 in FIG. 1, provides the cam action on the protrusion of the rocker arm 19, the rotation of which is transmitted to the movable part 3, the infusion part, providing its rotation.

The connection between the beam 19 and the movable part 3 can be carried out by means of a finger 22 inserted into the fork 23 of the movable part, as shown in FIG.

The axis of rotation of the rocker arm 19 is located in the slider 21, shown in figure 1 and indicated in figure 2.

The specified connecting part moves the movable part 3 under the pressure of the cam 16.

Other means for transmitting rotational motions and moving the movable part 3 of the infusion chamber 1 will be described below.

In a preferred embodiment, the rocker arm 19 comprises an extension defining a travel stop 20 and which is capable of abutting against the abutment surface when a certain angular position of the movable part 3 of the infusion chamber is reached in the open position of the upper part of the infusion chamber 1.

According to a first embodiment, the shaft 13 is driven by a mechanical drive.

According to a second embodiment, the shaft is driven into rotation by turning the lever 15, which can be set in motion by the user.

6 and 7 depict two positions of the lever 15.

In the embodiment of FIG. 7, the position of the lever 15 determines the position of the cam 16, exactly corresponding to the working phase shown in FIG.

In this case, the movable part 3 is inclined downward to form a supporting surface 6 in its upper part, for interaction with the lower outer surface of the container 2.

According to the position of the lever 15 according to FIG. 6, the cam 16 pivots and reaches the position shown in FIG. 2, in which the infusion chamber 1 is closed in the extraction position.

The rotation of the lever 15 can be limited by means of a movable stop 28, made, for example, in the form of a finger moving in the oval hole of the frame of the device.

In order to ensure or improve the tightness of the infusion chamber 1 in the closed position, it is advantageous to increase the closing force produced by the user with the lever 15 with an additional force.

To this end, the locking means when closing the two parts 3.4 of the infusion chamber 1 can be performed, as will be shown below.

Preferably, the device also contains means for guiding the container 2 during its movement in the working phases.

For this, the guiding means can be made in the form of a guide 25 formed by two grooves 26, intended to surround the periphery of the container 2.

The periphery of the aforementioned container 2 can be inserted into each of the grooves 26 provided for this.

It is advantageous to install the guiding means movably to synchronize with the approaching and removing movements of the two parts of the infusion chamber.

To this end, these means are jointly moved with the slider 21 by means of the pushers 31, presented, in particular, in Fig.7.

The pusher 31 contains a part with a groove 32, forming two areas of pressure of the pusher 31 on the corresponding surface of the guide means.

Thus, the movement of the guide means corresponds to the movement of the slider 21 in the working phases.

On the other hand, the gap formed between the two pressure surfaces formed by the groove 32 first allows only the movable part 3 to advance, and then the guiding means and the movable part 3 to move together towards the stationary part 4 of the infusion chamber 1.

The pusher system, made in this way, can be implemented around two side guides 30a, 30b, providing direction when moving the movable elements and the adhesion of the components of the device.

The working phases of this device are depicted in more detail in Fig.8-14.

Fig. 8 schematically represents various phases of movement of a portion 3 of the infusion chamber 1.

The arrows schematically show the movement of the movable part 3, carried out by turning the cam 16.

At the same time, sections A-A and B-B in Fig. 8 schematically depict the implementation of cam 16 and, in particular, the execution of two external supporting surfaces 17 and 18.

The surface 18 acts on the end of the rocker arm 19.

9-12 and 9bis, 10bis, four successive stages of the operation of the claimed device are shown.

In figure 9, the cam 16 is set in motion and causes the rotation of the movable part 3, which tends to open to receive the container 2.

The upper part of the movable part 3 of the infusion chamber tilts, the supporting surface of the load 6, formed at its level, moves away and causes the container 2 to fall under the action of gravity.

The movable part 3 of the camera receives a container that rests on the surface 5, forming the supporting surface of the reception.

As a result of the subsequent rotation of the cam 16, the movable part 3 of the camera moves, as shown in FIG. 10.

At the same time, the movable part 3 also continues to rotate in order to reach a position strictly parallel to the position of the stationary part 4, until they fully close as a result of translational movement, as shown in Fig. 9bis and 10bis. Thus, the bringing of the movable part 3 to the stationary part 4 is carried out along the optimal path, which ensures the contact of the surfaces of the two parts 3.4 in the closed position.

After closing the infusion chamber, hot water enters the infusion chamber, as shown by the arrows in FIG. 10.

The drink first goes to the tray, and then to the funnel.

Once the extraction is done, the reverse movement of the cam 16 leads to the departure of the movable part 3 and its further rotation.

The movable part tilts, the container 2 is released and falls under the action of gravity into the extraction zone.

The movable part 3, thus turned downward, again provides the formation of the support surface 6 of the download on the upper part of the movable part 3.

Figures 13 and 14 show, in side view, the execution of the movement of the guides, if any.

To do this, a pusher 31 is used, made with the possibility of ensuring the advancement of the guides 25 as the moving part 3 moves.

The groove 32 provided on the pusher 31 provides a delay in the movement of the guides 25.

Fig. 14 shows the completion of the removal of the container 2, which is carried out as soon as the movable part 3 is moved away while the guides 25 are still in place.

When the container is removed, the guides 25 in turn undergo movement in the direction indicated by the hollow arrows.

The delay in moving the guides 25 ensures the necessary lag of the container 2 before returning the device to its original position.

Another embodiment of the drive is presented below with reference to FIGS. 15-22.

On Fig as an example, the position of the axis of rotation 8 of the movable part 3 of the infusion chamber and the axis 7 of the movement.

A single drive consists of a drive shaft 33 with a horizontal axis of rotation and is configured to move the movable part 3.

To this end, the shaft 33 interacts with at least one connecting rod 34a, 34b, preferably with two connecting rods. According to Fig. 18, the connecting rod 34a, 34b is mounted with a movable link 37, 36 on one side of the shaft 33 and the other side on the rear end of the movable part 3 of the infusion chamber.

The movement of the slider 21 is also synchronized with the movement of the movable part 3 of the camera and provides a movable axis 8 connection of the aforementioned movable part 3 of the camera.

The movement of the slider 21, in addition, is controlled by means of direction, which may consist of two side guides 30a, 30b, as follows from Fig.16.

According to a first embodiment, the shaft 33 is driven by a mechanical drive.

According to a second embodiment, the rotation is driven by turning the lever 15 by the user.

Accordingly, the movable part 3 is inclined downward to form a supporting surface 6 in its upper part, for interaction with the lower outer surface of the container 2.

The surface 6 thus forms a support during the loading phase of the container 2.

In order to improve the tightness of the infusion chamber 1 in the closed position, it is required to increase the closing force produced by the user with the lever 15 with an additional force.

The locking means when closing the two parts 3.4 of the infusion chamber 1 can be performed as shown below.

Preferably, the device also contains the guiding means of the container 2 during its movement in different working phases.

To this end, the guide means can be made in the form of a guide 25 formed by two grooves 26 surrounding the periphery of the container 2.

The peripheral region of the aforementioned container 2 can be inserted into each of the grooves 26.

It is advantageous to install the guiding means with the possibility of their movement to track the movement of approach and the removal of two parts of the chamber.

To this end, the guiding means are moved together with the slider 21 by means of pushers 31 shown in FIG.

The pusher 31 contains a part with a groove 32 constituting two areas of pressure of the pusher 31 on the corresponding surface of the guide means.

Thus, the movement of the guide means corresponds to the movement of the slider 21 in the operating mode.

On the other hand, the gap formed between the two pressure surfaces formed by the groove 32 first provides advancement of only the movable part 3 of the infusion chamber, and then the joint advancement of the guiding means and the movable part 3 towards the stationary part 4 of the chamber 1.

The pusher system, made in this way, can be implemented around two side guides 30a, 30b, providing direction when moving the movable elements and the adhesion of the components of the device.

The working phases of this device are illustrated in more detail in FIGS. 17-22 and allow implementing the steps of making a beverage with the same configuration changes of the infusion chamber 1 as in the first embodiment.

17 and 18 show a first operating position of the device in which the container 2 is in the abutment position in the upper wall of the movable part 3.

The lever 15 is in a predetermined angular position, in this case, vertical.

The movement of the lever 15 allows you to reach the position shown in Fig.19 and 20, in which the container 2 is installed in the movable part 3 of the infusion chamber.

Between these two phases of movement, the drive shaft 33 presses the connecting rod 14a onto the rear of the movable part 3 of the chamber and, in particular, rotates the movable part in a clockwise direction.

Continuing the rotation of the lever 15, the shaft 33 exerts additional pressure on the movable part 3 by means of connecting rods 34a, 34b, causing the movable part 3 of the chamber to move and close, to form the extraction chamber 1.

Persistent surfaces may be provided, in particular on the slider 21, to limit the angular mobility of the movable part 3 of the chamber.

Thus, in the position shown in FIGS. 21 and 22, the movable part 3 closes the extraction chamber 1.

When the infusion chamber is closed, hot water is supplied to the infusion chamber.

The drink enters tray 13.

Once the extraction is done, the reverse movement of the shaft 33 is accompanied by the departure of the movable part 3 and its rotation.

Subsequently, the movable part 3 of the chamber is tilted, the container 2 is released and falls under the action of gravity into the extraction zone.

The movable part 3 of the chamber 1, thus turned down, again provides the formation of the support surface 6 of the download on the upper part of the movable part 3.

On Fig, 19 and 21 depicted on the side view of the movable guide means.

In particular, a pusher 31 is provided, causing the guides 25 to advance as the moving part 3 of the camera 1 advances.

The groove 32 provided on the pusher 31 provides a delay when moving the guides 25.

The removal of the container 2 is completed as soon as the movable part 3 is moved away, while the guides 25 are still in place.

In the two embodiments shown, the drive can be carried out manually by turning the handle or lever. Tightness is ensured or improved by turning additional locking means. Thus, a machine of simplified design is obtained, while maintaining its effectiveness, and, in particular, its tightness.

Next, a preferred embodiment of the additional locking means will be described with reference to FIGS. 23 and 24.

In the case shown in Figs. 23 and 24, additional locking means provide longitudinal movement of the small stroke of the stationary part 4. Thus, as soon as the movable part 3 reaches the closing position of the infusion chamber 1, this longitudinal movement of the small stroke allows you to provide or increase the relative pressure two parts 3, 4 on the peripheral zone of the container 2. Thus, a zone is created on the peripheral tightness shown in Fig.24.

In accordance with the above embodiment, the means of longitudinal movement are formed by the hydraulic cylinder 38. The hydraulic cylinder 38 is supplied from the same source as the infusion chamber 1, namely, from the boiler 9. Thus, additional locking means do not require the formation of another hydraulic system.

As shown in FIGS. 23 and 24, the piston of the hydraulic cylinder 38 is formed by a movable body 41, rigidly connected to the rotating part 4 of the chamber, with the possibility of ensuring its advancement or withdrawal in accordance with the working position of the hydraulic cylinder 38. Liquid under pressure (in particular hot water from the boiler 9) enters the chamber 39 to exert pressure on the movable member 41. The chamber 39 is formed between the movable member 41 and the surface 40 of the boiler 9, while the surface 40 preferably has a small cavity that provides sufficient on the volume of the camera 39.

In the surface area 40, the boiler 39 comprises a tap 42, which supplies hot water to the chamber 39.

To ensure a tight seal of the chamber 39 of the hydraulic cylinder 38, sealing means are provided. In particular, gaskets or an elastic impermeable membrane 43 shown in FIGS. 23 and 24 can be used.

The elastic impermeable membrane is formed from an element rigidly and hermetically sealed around the perimeter with its outer edge to the surface 40 of the boiler and its inner edge to the movable body 41. The elastic impermeable membrane 43 is deformed in accordance with the operating position of the hydraulic cylinder 38.

Obviously, when hot water enters the chamber 39 from the boiler 9, the volume of the chamber 39 tends to increase, and pressure is applied to the corresponding surface of the movable organ 41. This pressure causes the movable organ 41 to move and, therefore, to move the non-rotating part 4 of the chamber, as shown in Fig.24. According to Fig.24, the locking is made.

At this stage, hot water can be supplied to part 4 of the chamber to produce forced extraction in the infusion chamber 1. Injection of water is carried out by a sprinkler 45 of a movable structure, made in the form of an inner coating of part 4 of the chamber.

Hot water is supplied to the infusion chamber 1 through the power channel 44 connecting the chamber 39 of the hydraulic cylinder 38 and the sprayer 45. To avoid the movement of water in the direction of the sprayer 45 in the inoperative position of the sealing means and in the open position of the infusion chamber 1, an additional device is provided.

In fact, as shown in FIGS. 23 and 24, the supply channel 44 comprises a valve 46 configured to open the supply channel 44 only beyond a pressure threshold whose value exceeds the working pressure of the hydraulic cylinder 38.

Thus, the supply of hot water to the chamber 39 through the outlet 42 of the boiler 9 first activates the hydraulic cylinder 38 and advances part 4 of the chamber, which provides additional locking.

After the locking is achieved, the pressure in the chamber 39 continues to increase until it reaches a level that allows the valve 46 to move to open the power channel 44 and supply hot water to the infusion chamber 1.

As an example, it is possible to adjust the pressure threshold of the valve 46 at a level of about 2 bar. This regulation can be carried out by selecting a spring 48, providing a return to the resting position of the valve 46.

After completion of the water supply to the infusion chamber 1, the supply of hot water to the chamber 39 is stopped to return the hydraulic cylinder 38 to the rest position. Such a return can be caused by the elastic properties of the membrane 43 and the return spring 47.

Thus, the user can manually, with limited effort, close or open the infusion chamber 1. When closing is carried out manually, additional locking means ensure complete tightness of the infusion chamber 1 in the peripheral tightness zone. In this case, complete extraction can be carried out with pressures corresponding to the pressures of espresso machines, and, in particular, of the order of 15 bar.

Without the use of additional locking means, it is especially difficult for the user to manually ensure sufficiently tight closure of the infusion chamber 1 when working with high pressure levels.
