Description

A HOT BEVERAGE PREPARATION MACHINE
The present invention relates to a hot beverage preparation machine comprising a control unit.
In hot beverage preparation machines, the water filled into the water container is heated by a water heater and is transferred to the brewing chamber containing raw material of the beverage to be prepared. The brewing process is performed in the brewing chamber as a result of the interaction between the raw beverage material and water. Afterwards, the brewed beverage is transferred into a pot and served. The hot beverage preparation process is composed of steps such as heating the water, transferring the water, brewing and transferring the brew. Hot beverage preparation machines wherein serving time can be programmed are preferred since they provide ease of utilization. However, since the hot beverage preparation steps depend on more than one parameter such as water heating time, brewing time, etc., hot beverage serving time may deviate from the planned time. This situation complicates the utilization of the machine.
In the state of the art Chinese Patent Document No. CN203481 1, an energy- saving and time-saving electronic cooker is disclosed, that is capable of delayed starting.

The hot beverage preparation machine of the present invention comprises a control unit that operates the water heater an estimated beverage preparation time predetermined by the producer and at least one tolerance time predetermined by the producer before the hot beverage serving time planned by the user. By means of the tolerance time, the hot beverage is enabled to be ready at the time planned by the user even if deviations may occur in the anticipated heating time and/or brewing time during the water heating process and/or brewing process.
In an embodiment of the present invention, the control unit keeps the temperature of the water inside the water container fixed if the actual water heater operation time is smaller than the predetermined estimated water heater operation time as long as the time difference between the estimated water heater operation time and the actual water heater operation time. Since the estimated water heater operation time and the tolerance time are determined by taking into consideration the worst case (low environment pressure, maximum water amount, etc.) in order to prevent the beverage preparation time from being effected by the deviations in the water heating time, the time difference between the estimated water heater operation time and the actual water heater operation time always remains inside the tolerance time. By means of the tolerance time, the water transfer process does not start after the heating process in case the actual water heater operation time does not reach the estimated water heater operation time predetermined by the producer. Thus, the beverage preparation process is prevented from being completed before the planned time.
In an embodiment of the present invention, the control unit delivers the beverage into the pot by means of the valve if the actual brewing time is smaller than the estimated brewing time predetermined by the producer, operates the pot heater until the end of the estimated brewing time and the tolerance time and enables the beverage to be served hot. Moreover, the control unit delays the beverage ready warning as much as the brewing tolerance time. Thus, the planned hot beverage serving time is prevented from being affected by variations in the brewing time. The hot beverage preparation machine realized in order to attain the aim of the present invention is illustrated in the attached figures, where:
Figure 1 - is the perspective view of a hot beverage preparation machine.

The hot beverage preparation machine (1) realizes the hot beverage preparation process composed of variable-time steps such as water heating, brewing, etc. and of fixed-time steps such as water transferring, brew transferring, etc. The hot beverage preparation machine (1) of the present invention comprises a control unit (7) that, in order to prepare the beverage at a hot beverage serving time (tp) planned by the user, operates the water heater (3) and thus starts the hot beverage preparation process an estimated beverage preparation time (hst) predetermined by the producer and at least one tolerance time (ts) predetermined by the producer before the hot beverage serving time (tp). By means of the tolerance time (ts), differences between the actual process times and the estimated process times do not change the planned hot beverage serving time (tp).
In an embodiment of the present invention, the control unit (7) stops the pump (6) and keeps the water transfer process waiting until the end of the estimated water heater operation time (ist) and the tolerance time (ts) . predetermined by the producer. The actual water heater operation time (isg) changes depending on a number of parameters such as the amount of the water to be heated, the temperature the water must reach by being heated, the temperature and the pressure of the environment wherein the water container (2) is situated. In case the actual water heater operation time (lsg) does not reach the estimated water heater operation time (ist), the temperature of the water inside the water container (2) is kept fixed, and the pump (6) is not operated and the water transfer process is not started until the estimated heater operation time (ist) and the tolerance time (ts) end. Thus, the hot beverage serving time (tp) is accurately planned, increasing user satisfaction.
In an embodiment of the present invention, the hot beverage preparation machine (1) comprises a pot heater (9) enabling the beverage in the pot (5) to be kept hot.
