DE2904569A1 - Tea machine with boiling time adjustment and strainer - has floatable container anchored to base of urn by weight with release switch - Google Patents

Abstract

In the hot drink preparation machine, the time for coming to the boil can be adjusted. It is used for automatic tea or coffee vending machines, where the time it takes the tea or coffee to be drawn to a given strength can be set. It also has the facility of removing the tea leaves or coffee dregs from the prepared drink. The machine consists of a floatable container for the tea or coffee which is prevented from rising by anchoring to the base of the brewing urn. The connection is made dependent on the heat and the brewing time. The anchoring and release mechanism is built into the floating container (1). There is a time switch which is linked to the setting mechanism which reacts to the temp. The anchor is in the form of a weight (7).

Description

Device for selecting the brewing time for

Hot drinks.

Device for selecting the brewing time when preparing Hot beverages, especially tea, and for the automatic separation of the tea leaves from the Infusion after the set brewing time has elapsed.

The invention is based on the object of creating a direction with which the brewing time for the preparation of hot beverages, especially with the Tea preparation, which is adjustable and which makes it possible to set after the expiry of the set Brewing time to separate the tea leaves from the infusion.

It is a known fact that it is used on it when making tea arrives that the tea is poured with bubbly boiling water and not constricted, but is extracted floating.

It is also important that depending on individual tastes and needs the brewing time can be kept shorter or longer.

Assuming that there is generally no problem, tea gushes Pouring boiling water over it is a problem time can be determined in a simple way or automatically and after the end of the the desired brewing time to separate the tea leaves from the infusion.

This problem, adherence to the desired brewing time - this is usually the case between 2 and 7 minutes when preparing tea and ends with the separation of tea and Sud - is intended by the invention described below and by way of example Embodiment will be explained.

Further details of the invention emerge from the description and on the basis of an exemplary embodiment according to Figs. I and III, as well as the Claims 1 - 10.

According to Fig. I, a tea strainer float (1) has a buoyancy generating Cavity (2), where anstel = le of the cavity (2) also a floating body is = could be arranged.

The tea container space (3) has a sieve (4) and a lid (5), the perforated on can.

A guide sleeve (6) is arranged in the center of the tea strainer float.

The tea strainer float stands with the anchor (7), which acts as an anchor plate can be designed and whose weight is heavier than the buoyancy of the Cavity, in connection. A guide rod (8) connected to the anchor protrudes into the guide sleeve (6).

The tea strainer float (1) is connected to the armature (7) by a holding device (9), e.g. a magnet or a spring catch.

The anchor holds the TeesTebschwTzmmer by its weight at the bottom of the Brewing vessel (10), even if the Vorrich = device is doused with water and the Teeslebschwimm = mer receives buoyancy through the cavity.

A temperature responsive actuator (II), e.g.

an expansion bellows, a bimetal or the like. Separates the tea strainer float (1) from the armature (7) only when the actuator (11 under the influence of temperature performs a work stroke that overcomes the holding effect of the holding device (9).

In the case shown, the holding device is a magnetic disk, or a magnet or iron ring, for example if the armature (7) is designed as a magnet is.

The holding device can also be designed so that at the bottom of the A hook or the like is attached to the brewing vessel and the tea strainer floats over a snap or resilient hook associated with the actuator is anchored to the bottom of the brewing vessel and the anchoring by the heat-responsive Actuator can be solved.

If the holding effect is canceled by the actuator, the tea strainer float can (1) Rise upwards in the infusion, whereby the tea leaves from the liquid over the surface can be lifted out.

The brewing time is made adjustable by presetting the adjusting screw (12) determines the distance (13) through which the working stroke, the the holding effect between the anchor and the Teeslebschwlmer is shorter or has to be longer.

With a short brewing time set - the distance (13) is set short - The actuator (11) releases the anchor and connection already with a short working stroke Tea strainer = float, whereas if the brewing time is set to a long time, the distance (13) is set large - the working stroke only overcomes this connection after a long journey and releases the tea strainer float.

Because the brewing temperature of the water is constant from case to case can be assumed, the temperature influence in the time unit on the Actuator responsive to heat is also constant.

The actuator (11) must have a previously determined shorter or Carry out a longer working stroke - this corresponds to the brewing time - in order to achieve the Tea strainer = float to be released from the anchorage, which ends the brewing time and the extracted tea is separated from the brew.

The tea strainer float (1) rises, as Fig. I shows, in the brew the dot-dash position (14). The sieve (4) is higher than that Liquid = mirror (15) of the tea brew. The wet and swollen = The tea leaves drip off and can easily come out of the tea container as a moist mass (3) can be removed.

In a further embodiment according to Fig. II and III a tea strainer float is used (1'1), which has a buoyant = generating cavity (2 "), a tea container space (3") and a tea container space designed as a sieve (4 ") = bottom, with a Anchor (7 ??), which is heavier than the buoyancy force of the cavity (2 "), through Holding means (9 ") connected and held down on the bottom of a brewing vessel (10"), even if the device is poured over the tea strainer float with water.

Inside the armature (7 ") there is an actuator which responds to heat or an encapsulated time switch built in, which after a preselected time has elapsed Time the separation between the anchor (7 ") and the tea strainer = float (1") brings about.

In the illustrated embodiment according to Figs. II and III is the tea container space (3 ") is open at the top and has a lamellar edge (16) which hugs the wall of the brewing vessel (10 ") slightly =.

On the one hand, this edge prevents the tea from floating below the tea strainer can reach and on the other hand allows that when the Teeslebschwlm = mers from the anchorage, this can swim upwards and the edge the swollen Tea particles on the wall of the brewing vessel 'wiped upwards.

The tea strainer swallower, which is open at the top, has the advantage that the tea can swim freely throughout the infusion during the brewing time.

If the teaspoon is in position C14 ") - this is shown in dash-dotted lines shown - obtained, the connection to the anchor (7 ") by a cord (17) or the like. Remain.

It is the advantage of Einrlch = described above services from tea strainer swimmers that they are in themselves an independent and automatic device represent and independently of other, e.g. externally acting means that Determine the brewing time of the tea and the separation of the extracted tea from the infusion bring about.

In particular, the first example embodiment described can be designed and dimensioned according to Fig direction in any suitable container for making tea, provided there is one sufficient large opening = has, can automatically prepare tea and it is also irrelevant is whether the boiling water enters the brewing vessel by hand or automatically.

In the case of an extension of the automation of the tea preparation, at which the boiling water preparation takes place automatically - similar to a coffee machine ten known - it is also conceivable to anchor the tea strainer float on the ground of the brewing vessel during the brewing time also with lying outside the brewing vessel To raise funds.
