DE3602231A1 - Tea-brewing appliance - Google Patents

Abstract

The vessel is provided at the bottom with the outlet which is closed by the valve under the action of the closing spring. The lid with the filling opening, it can be closed by the flap, is connected to the vessel by a quick-acting closure. A mechanical timer with the adjusting knob is installed in the housing. After expiry of the set drawing time, the timer mechanically actuates the valve stem, whereby the valve opens and the tea can flow into the vessel on which the tea-brewing appliance is placed. The apparatus only allows an outflow if a vessel e.g. a teapot, has been placed on it, the lever thereby freeing the valve. It is advantageous to arrange the apparatus in a multiple arrangement. Owing to the quick-acting closure, the vessel can be easily exchanged, so that a taste transfer when brewing different types of tea is avoided. The flap starts the timer upon closure. After the tea has flown out, the flap is put into the position and the new drawing time set, thereby closing the valve, as a result of which dripping is prevented when the appliance is removed.

Description

The "tea machines" on the market are for the daily use too complicated. If z. B. one after the other different types of tea are to be brewed, e.g. B. Herbal Tea and then immediately black tea, then required this is sometimes a very cumbersome disassembly and assembly.

The device described below is very simple consists of only a few parts and is therefore inexpensive. It allows the use of tea bags, Tea filters and tea eggs. Handling is easy. A Dripping after the tea has poured out is avoided. A spill lock prevents the tea from flowing out after the Drawing time, unless the device is on z. B. set up a teapot becomes.

Fig. 1

With ( 1 ) the drawing vessel is designated which is made either of glass or a transparent plastic as possible. ( 2 ) are 3 feet on the bottom of the vessel ( 3 ). The outlet ( 4 ) receives the valve ( 7 ) and is closed by the same. The valve stem ( 6 ) is loosely guided in the sleeve ( 5 ), the closing spring ( 8 ) acts on ( 6 ) and is supported against ( 5 ) and the spring ring ( 9 ). The valve ( 7 ) is shown as an example as a poppet valve.

The lid ( 12 ) with the vessel ( 1 ) z. B. connected by means of a bayonet lock not shown, so that ( 1 ) and ( 12 ) are easy to disassemble. The filler opening ( 13 ) can be closed with the flap ( 15 ) pivoting about the hinges ( 14 ). The locking bolt ( 17 ) is attached to ( 15 ). The housing ( 18 ) accommodates the front plate ( 30 ) which is designed as a carrier for the mechanical linear drive with an adjusting knob ( 20 ). The zero mark is identified by ( 19 ).

Fig. 2
This is a top view of the lid ( 12 ). ( 13 ) is the filling opening, ( 14 ) the hinges, ( 15 ) the flap in the locked position ( 16 ), ( 18 ) the housing for receiving the drive, ( 19 ) the zero mark, ( 20 ) the adjusting button for the pulling time pre-selection and ( 30 ) the front panel of the drive. The handle is designated in Fig. 1 and Fig. 2 at 29.

Fig. 3:
Here the flap ( 15 ) is shown in the closed position. ( 21 ) is a hole in which the hook of the chain of a tea infuser can be hung. ( 22 ) are slotted holes in which the threads of tea bags can be hung. This is done in pos. ( 16 ) of the flap ( 15 ).

Fig. 4:
A conical spring is embedded in the plate ( 7 ) of the plate valve with sealing ring ( 10 ). It is designated by ( 11 ), the material is plastic or a corrosion-resistant metallic material. The spring force is adjusted so that when the device is placed on the shelf ( 28 ), the spring pressure on the valve plate ( 7 ) is greater than the mechanical pressure which the time drive exerts on the valve stem ( 6 ) after the pulling time has elapsed.

Fig. 5:
The safest method to avoid the tea escaping from the vessel ( 1 ) is achieved by placing ( 1 ) on the edge e.g. B. a teapot is used. On the bottom of the vessel ( 3 ) 3 bearing blocks ( 23 ) are attached offset by 120 °. If ( 1 ) is made of plastic, the parts ( 23 ) can be molded on immediately.

In ( 23 ) three levers ( 24 ) ( 25 ) are mounted. The leaf spring ( 26 ) is supported against the bottom of the vessel ( 3 ). As a result, the end ( 25 ) lies from below against the edge of the valve ( 7 ). The three springs ( 26 ) of the levers (( 24 ) ( 25 ) are adjusted so that the pressure force on the valve ( 7 ) is higher than the opening force which the expired timer exerts on the valve stem ( 6 ) from above ( 7 ) can only open when the lever part ( 24 ) is pushed upwards against the force of the leaf spring ( 26 ) by placing the vessel ( 1 ) on the edge of the can ( 27 ), thereby pivoting the end ( 25 ) downwards , the valve ( 7 ) is released.

The time drive is controlled as follows: When the flap ( 15 ) is in position ( 16 ) it blocks ( 17 ) the sequence of the time drive, but allows the desired drawing time to be set. Is set at ( 20 ) z. B, after inserting the teabag threads in ( 22 ) ( Fig. 3) the flap is closed after pouring the sprudenlden water into ( 13 ), then the time drive is started because ( 17 ) releases the time drive by swinging it away.

After the tea has run out into the pot, the flap ( 15 ) is pivoted into position ( 16 ) and the time desired for the next infusion is set at ( 20 ). This closes the valve ( 7 ), the sequence of the time drive is blocked by ( 17 ). The closed valve ( 7 ) prevents dripping from the vessel ( 1 ).

When brewing another type of tea, the container ( 1 ) is changed.
