Abstract

Device permitting multiple filtration in immersion through the bottom, with double wall. The invention consists of the pot (1) equipped internally with the filter tube (2). A piston (6) will filter the coffee through the bottom with the aid of the screen (3) and will return it as many times as required. This method achieves a saving of 20% of the coffee while producing the maximum amount of aroma. This method is self-cleaning. It can be used for making tea or any other infusion. Espresso coffee can be made by filling the filter tube (2) only.

Description

La présente invention concerne une cafetière théière et expresso double parois permettant de multi-filtrages par autocirculation en immersion - autonettoyant
La présente invention permettant le multi-filtrages, procédé très économique, réalise un café à 20% d'économie en effet, le café filtré retourne dans le corps central et il est injecté à nouveau à laide du piston plein, en filtrant par le fond en immersion. La double paroi isole le café dans le corps central et permet de garder la chaleur très longtemps.The present invention relates to a double-walled espresso and teapot coffee maker for multi-filtration by self-immersion circulation - self-cleaning
The present invention allowing multi-filtering, a very economical process, achieves a 20% saving coffee indeed, the filtered coffee returns to the central body and it is injected again using the full piston, filtering from the bottom in immersion. The double wall isolates the coffee in the central body and keeps the heat for a very long time.

La cafetière est auto-nettoyante, seul le filtre central est à vider.The coffee maker is self-cleaning, only the central filter needs to be emptied.

L'appareil Cfigure 1] selon l'invention se compose d.Wun corps [4] pot cafetière cylindrique ou autre de contenance variable. A l'intérieur de ce pot [1] un tube droit (2) d'un diamètre inférieur à celui du pot C1] plonge jusqu'au fond de celui-ci. Ce tube [2] sera muni à sa base d'un tamis [3] empéchant tout dépôt. Ce tube-filtre [2] possède des découpes [4] en sa partie supérieure qui permettent le passage du café déjà filtré venant des deux parois (5]. The apparatus Cfigure 1] according to the invention consists of d.Wun body [4] cylindrical or other coffee pot of variable capacity. Inside this pot [1] a straight tube (2) with a diameter smaller than that of the pot C1] plunges to the bottom of the latter. This tube [2] will be provided at its base with a sieve [3] preventing any deposit. This filter tube [2] has cutouts [4] in its upper part which allow the passage of already filtered coffee coming from the two walls (5).

Un piston plein [6] avec des joints [7] tige [8] et couvercle [9] bouton [10] pénètre à l'intérieur du filtre [2]. A full piston [6] with seals [7] rod [8] and cover [9] button [10] penetrates inside the filter [2].

Le fonctionnement de l'appareil est le suivant
On place le tube-filtre [2] à l'intérieur du pot [1]; on dépose la mouture de café dans ce tube-filtre [2] que lion remplit d'eau chaude jusque sous les découpes [4]. Le café commence doucement à être filtré par le tamisE3] au fond du tube [2]. On place alors le piston plein [6] en position haute jusquien dessous des découpes (4], à ce moment la descente et le filtrage du café sont stoppés car il y a en haut obturation du tube-filtre (a]. Selon la quantité de café désirée on rajoute alors le complément d'eau qui se place dans la double paroi [5].Le couvercle (9] est descendu en haut du pot [1], on presse le piston [5] une fois jusquiau fond puis on le rappelle en position haute afin de reprendre l'eau d'entre la double paroi [5] et de la recycler. On laisse alors décanter 4 minutes environ puis on presse doucement sur le piston 6] jusqu'au fond, le café filtré par le tamis 3] monte dans la double paroi [5] et se dépose au-dessus du piston [6] dans le tube-filtre [2]. On remonte le piston [6] jusqu'en haut. The operation of the device is as follows
The filter tube [2] is placed inside the pot [1]; the coffee grounds are placed in this filter tube [2] which the lion fills with hot water up to the cutouts [4]. The coffee slowly begins to be filtered by the sieveE3] at the bottom of the tube [2]. We then place the full piston [6] in the high position until below the cutouts (4), at this time the descent and filtering of the coffee are stopped because there is a top closure of the filter tube (a). Depending on the quantity of desired coffee, the additional water is then added, which is placed in the double wall [5]. The cover (9) is lowered to the top of the pot [1], the piston [5] is pressed once to the bottom and then recall it to the high position in order to take up the water between the double wall [5] and recycle it, then leave to settle for about 4 minutes then gently press on the piston 6] to the bottom, the coffee filtered by the sieve 3] rises in the double wall [5] and is deposited above the piston [6] in the filter tube [2]. The piston [6] is raised up to the top.

L'auto-circulation est alors créée. Un arôme supplémentaire sera apporté au café chaque fois que ce mouvement sera effectué.Self-circulation is then created. An additional flavor will be added to the coffee each time this movement is made.

Ce qui explique une économie de 20%.This explains a saving of 20%.

La cafetière est auto-nettoyante, seul le tube-filtre (] central est à vider. The coffee maker is self-cleaning, only the central filter tube (] must be emptied.

Le meme appareil permet la réalisation expresso : on ne remplira alors que le tube-filtre (] selon la quantité désirée. The same device allows espresso production: we will only fill the filter tube (] according to the desired quantity.

On place le piston [6] en position haute et on le descend légèrement en le rappelant immédiatement afin de faire retourner la totalité de l'eau dans le tube-filtre [2]. Après décantation on descend le piston [6] jusqu'au fond, une ou plusieurs fois selon la force du café désirée.The piston [6] is placed in the high position and it is lowered slightly, recalling it immediately in order to return all the water in the filter tube [2]. After decanting, the piston [6] is lowered to the bottom, one or more times depending on the strength of the desired coffee.

Ce dispositif est valable pour le thé ou toute autre infusion, l2économie existant toujours grâce au multi-filirage. This device is valid for tea or any other infusion, the economy still existing thanks to multi-spinning.

Il est entendu que l'on peut apporter des modifications de construction à ce qui a été décrit sans pour cela sortir du cadre de l'invention. It is understood that construction modifications can be made to what has been described without departing from the scope of the invention.
