Specifically, thermostat 7 is connected on the pedestal 8 of calorifier 2, and is arranged in the outside of calorifier 2.
Suitably, as shown in drawings, thermostat 7 is comprised in the housing 9 on the bottom that is connected to calorifier 2.
By this way, housing 9 is configured for the support of calorifier 2.
Calorifier 2 and distributor 5 are by Heat Conduction Material, and for example metal is made, and hydraulic accumulator 6 has the shell of being made by heat-barrier material 11.
Hydraulic accumulator 6 has the pedestal of being made by Heat Conduction Material 12, and pedestal 12 is connected with shell 11 with distributor 5.
Pedestal 12 has the part that is threaded for calorifier 2, thereby heat can be delivered to distributor 5 from calorifier 2 through pedestal 12 by conduction.
Power line 30 is placed between the phase line L and zero line N of electrical network, and powers to electric heater unit 3 through connector 22.
Now particularly with reference to Fig. 2, device 1 comprises a detection system of surveying lack of water in the calorifier 2, when arrive thermostat 7 the first time the described electric heater unit 3 that outage is interfered power-on time when being less than or equal to a predetermined threshold, this detection system is suitable for being used for sending alarm signal.
The detection system that only shows its electric diagram comprises a control module 32, microcontroller preferably, and control module 32 is communicated by letter with the sniffer 31 on being connected to power line 30, and is suitable for surveying the existence of the power supply of heater 3.
Control device 31 preferably includes one and in series is placed on branch road in the power line 31 with heater 3.
Control module 32 has: the storage device (not shown) is suitable for being used for storing at least above-mentioned predetermined threshold time value; The calculation element (not shown) is suitable for being used for calculating the actual power time that the first time, outage was interfered that arrives thermostat 7; The comparison means (not shown) is suitable for being used for the real time is compared with above-mentioned threshold time value; And the generating apparatus (not shown), be suitable for when the real time is less than or equal to the predetermined threshold time value, producing alarm signal.
Control module 32 is also communicated by letter with at least one output unit of alarm signal.

Best, control module 32 is connected with a switch 33 that inserts along power line, and is opened by the alarm signal order, to interrupt the power supply of heater 3.
In a preferred embodiment, the switch 33 of being ordered is the form of relay.
Best, control device 31 and the switch 33 of being ordered are integrated on the same chip of control module.
Control module 32 can order electric heater unit 3 power supply startup or interrupt to produce coffee beverage, and also have time set, this time set is suitable for being used for interrupting the power supply of heater 3 after the scheduled time limit that the production from the coffee base beverage begins; In practice, when the coffee base beverage was ready to, uninterrupted power supply-power supply only interrupted after the certain hour section, with the insulation beverage.
The operation of this device is as follows.
When the generation that need be engaged in based on the small piece of land surrounded by water of coffee uniform, thermostat 7 is under the approval condition of power supply of heater 3.
The temperature and pressure of water raises gradually in calorifier 2, begins to keep container 4 (this container comprises coffee powder) to produce the coffee base beverage by powder up to water; This beverage passes distributor 5 again and is stored in the hydraulic accumulator 6.
In this case, the temperature of calorifier 2 also experiences slowly and rising gradually, and this rising causes that interfere with the first time of thermostat 7 as we see, makes 3 outages after the complete emptying of calorifier of heater.
When the coffee base beverage was ready to, control module 32 did not also reach the terminal point of predetermined amount of time, still allowed power supply to electric heater unit 3 power supplies.
Therefore, electric heater unit is still for electric power is arranged, and heat-this heat that produces is no longer absorbed by the water that is included in calorifier 2 because calorifier is actually empty, and the conduction by through wall, pedestal 12 and the distributor 5 of calorifier 2 itself is delivered to the coffee base beverage that is included in the hydraulic accumulator 6.
Thermostat 7 remains on control down with the temperature of the pedestal 8 of small piece of land surrounded by water hydrophone, and prevent to reach may be to installing 1 harmful too high value.
Specifically, when the temperature of the pedestal 8 of small piece of land surrounded by water hydrophone 2 reached maximum limit (depending on the calibration to thermostat 7), the electric power that thermostat 7 interrupts electric heater unit 3 was supplied with.
When temperature drops to minimum of a value when following, thermostat is switched to the electric power of electric heater unit again and supplies with.
By this way, during the finite time after the coffee base beverage preparation in, connect electric heater unit discontinuously.
When control module 32 detects programming time period (for example, after it is connected 30 minutes), interrupt electric power supply to electric heater unit.
Let us is when the user need produce beverage now, and how the lack of water detection system works.
In requirement according to the user, switch 33 closures that control module 32 orders are ordered.
Branch road 31 has the potential difference that is directly proportional with electric current by heater 3 in its end.
This current potential never null value of electric current changes to the nonzero value that electric current is arranged.
After quilt switch 33 closures of ordering, stop to supply with and having null value during disconnecting circuit 30 when thermostat 7 in the potential difference of the end of branch road 31, and start the electric power supply of heater 3 and have nonzero value during closed circuit 30 when thermostat 7 to the electric power of heater 3.
Calculation element is connected on the sniffer 31, specifically, is connected on the branch road, and supplies with as long as sniffer experience non zero potential difference just defines the electric power of heater 3.
By this way, calculation element can calculate from interfering for the first time and actual power time to electric heater unit 3 of passing through when stopping heater 3 when being closed into by the switch 33 of being ordered when thermostat 7.
At this moment calculation element arrives coupled comparison means to the transfer of data relevant with the real time, and comparison means is compared the data that receive with the predetermined threshold that obtains from storage arrangement.
Under the situation of real time greater than predetermined threshold, system does not send alarm signal therein, and under reverse situation, control module command generator device sends alarm signal.
Alarm signal can be sent to the switch 33 that display and/or audible alarm unit and/or quilt are ordered, so that make power circuit 30 outages immediately.
In an object lesson, calorifier 2 is equipped with under the situation of water therein, for interfering for the first time of thermostat 7 real time that needs may be greater than 120 seconds, and calorifier is that the real time that needs under the situation of sky may be less than 90 seconds therein, because in this case, between calorifier and water, do not have the temperature of heat exchange and calorifier 2 more promptly to raise, so the threshold values time value is fixed to and is a bit larger tham 90 seconds.
So the apparatus and method that are used for preparing the coffee base beverage of imagination are carried out multiple modifications and changes easily, and all such modifications and change are all covered by notion of the present invention; Moreover all details can both replace with the element of technical equivalences.
