Milk steams milk, to provide coffee with milk bland.
(c) the discarded movement of coffee grounds
If above-mentioned coffee liquid extraction movement terminates, beverage supply device 100 carries out the discarded movement of coffee grounds.Firstly, such as
Shown in " the removing residual pressure " of Figure 12, the state that control unit 50 maintains hot water supply valve 23 to close opens drain valve 26 simultaneously
And close extraction valve 28.Then, the pressure reduction in cylinder 311 pressurizeed.If in cylinder 311 being common pressure, such as
Shown in " sucking " of Fig. 9 and Figure 12, control unit 50 makes the reversion of motor 34 drop piston-cylinder unit 31 (cylinder 311 and piston 312)
Under.At this moment, control unit 50 closes hot water supply valve 23 and drain valve 26, and extraction valve 28 is opened.Then, in cylinder 311
Spatial volume increases with the decline of piston-cylinder unit 31, thus cylinder 311 in be negative pressure, can will from outlet port 37A to
Remaining coffee liquid is drawn into cylinder 311 in piping until coffee liquid taking-up portion 37B and in coffee liquid piping 27.
If control unit 50 makes piston-cylinder unit 31, (cylinder 311 and piston 312) is further fallen, as shown in figure 9, being located at gas
The lower end of the lowermost piston 312 of cylinder unit 31 is abutted with the lower surface portion 36B of frame portion 36.If control unit 50 also continues dropping
Lower movement, then the lower end of piston 312 collides lower surface portion 36B, so that piston 312 rises in cylinder 311.
Remaining coffee grounds is collected in the upper surface of piston 312 and is gradually increasing in cylinder 311 as a result,.Cylinder
Unit 31 is further fallen, if being lowered to lower position, is detected by lower position detection sensor 44 to the position.Root
According to the detection carried out by the lower position detection sensor 44, control unit 50 stops the driving of motor 34, stops lifting unit 32
Decline.In this state, as shown in " separation " of Figure 12, the coffee grounds for being collected in the upper surface of piston 312 is pushed cylinder
Outside 311, the position against the top positioned at the edge of the upper surface opening than cylinder 311.
Here, as described above, hot water supply valve 23 and drain valve 26 are closed, therefore on piston 312 is in cylinder 311
It is negative pressure between the upper end of piston 312 and the interior bottom of cylinder 311 when rising.Moreover, as described above, piston 312 is with permeable
Property, it is introduced into cylinder 311 so being gathered in moisture contained by the coffee grounds of the upper surface of piston 312 by piston 312.Scheming
In 12, introduced moisture is indicated with " raffinate ".Thereby, it is possible to reduce moisture contained by coffee grounds, therefore, carry out hereafter
In the removing movement of coffee grounds, the coffee grounds containing moisture can be eliminated and be adsorbed in 312 upper surface of piston and remove with being unable to fully
It the undesirable situation such as goes, can suitably remove coffee grounds.
If piston-cylinder unit 31 is lowered to lower position, next as shown in Figure 10, control unit 50 transfers motor 34 just
Increase once again piston-cylinder unit 31.If piston-cylinder unit 31 reaches defined height and position, wiper 38 and piston-cylinder unit 31
Lifting action is acted in linkage.Wiper 38 is located at the upper end than cylinder 311 slightly by the position of top as described above,
If wiper 38 carries out wiping action, is swept away by wiper 38 and removed by the coffee grounds shifted on piston 312 outside cylinder 311
It goes.Here, the coffee grounds being removed is contained in above-mentioned coffee grounds receiving unit 15.
(d) piston position return action
After coffee grounds is discarded, control unit 50 continues increase to execute piston position return action lifting unit 32.?
In piston position return action, control unit 50 as shown in Figure 11, rotates forward motor 34, senses until being detected by upper limit position
Until device 41 detects that piston-cylinder unit 31 is in upper limit position.Detect that piston-cylinder unit 31 is in upper limit position and means end cap 37
It is embedded into the most deep of cylinder 311.At this moment, the topmost of cylinder 311 is pulled up in the discarded movement of above-mentioned coffee grounds
Piston 312 is abutted with the lower surface of end cap 37, and the interior bottom of cylinder 311 is pressed by the rising of piston-cylinder unit 31
Portion.
In this process, as shown in " waste liquid " of Figure 12, control unit 50 is open by drain valve 26.As a result, in above-mentioned coffee
The moisture that the space between the interior bottom of cylinder 311 and piston 312 is attracted in the discarded movement of slag passes through drain valve 26 from row
Water pipe 25 is swimmingly discarded into outside.
Moreover, state, i.e. above-mentioned standby mode if the interior bottom that the position of piston 312 is pressed to cylinder 311,
Then control unit 50 stops the rotation of motor 34, and closes hot water supply valve 23, drain valve 26 and extraction these wholes of valve 28
Valve, carry out standby until receive coffee draw out operation next time.
More than, the coffee supply movement of the beverage supply device 100 of embodiments of the present invention is illustrated.It will be upper
The coffee supply movement stated is envisioned for each portion.But in above-mentioned coffee liquid
In extraction movement, generated sometimes in the coffee liquid taking-up portion 37B from piston 312 via coffee liquid piping 27 to coffee nozzle 4

The stipulated time is continued with first-class.
In addition, control unit 50 monitors pressure sensor 291 when coffee liquid extraction acts.In pressure sensor
Pressure in the cylinders 311 of 291 detections be act high defined threshold value or more than common coffee liquid extraction, and the state after
In the case where having continued the stipulated time or more, control unit 50 closes hot water supply valve 23, stops heat-exchanger pump 12.
In addition, control unit 50 monitors the FG signal exported from the rotor position detecting sensor 341 of motor 34.FG
Signal is the signal exported along with the rotation of motor 34 from rotor position detecting sensor 341, so in order not to making to go up and down
When the coffee extraction that portion 32 goes up and down and stops motor 34 acts, it should can't detect FG signal.That is, if control unit 50 is in coffee
Extraction detects FG signal when acting, then means that motor 34 has started reversion due to the pressure in cylinder 311.Therefore, it controls
When portion 50 processed detects FG signal under the stopped state of motor 34, it is judged as abnormal, that is, is judged as and detects that coffee liquid supplies
The blocking of access is answered, and closes hot water supply valve 23, stops heat-exchanger pump 12.
In this way, control unit 50 when coffee liquid extraction acts, carries out following monitoring: by flow sensor 22 carry out to heat
The monitoring of the supply of water, by pressure sensor 291 carry out to the monitoring of the pressure in cylinder 311 and to from rotor position
