It is provided with thick film heating device 4, the top plate 2 on water inlet 21 and steam port 22, the base 3 and is provided with delivery port 31.
Cartridge heater 1 is fabricated by by stainless steel 430, and external diameter is φ 76mm, and length is 40mm, and thickness is 1.2mm.
Top plate 2 is fabricated by by stainless steel 430, is fixed by welding on cartridge heater 1.
The specification of thick film heating device 4 is 220V, 80W.
Base 3 is die casting aluminium coffee brewing seat.
The heating of thick film heating device 4 is transferred heat in heating chamber 5 by stainless steel cartridge heater 1, and the water inside heating chamber 5 is heated
To suitable temperature, the capacity of storage water heater heater 73 is 180ml, and the water in heating storage water heater heater needs the used time for the first time
60s, can continuously go out 4 cups of 30ml espresso coffees, water temperature is 90 ° -92 ° during processing coffee.
Further, the water inlet 21 is provided with the water inlet pipe 211 extended downwardly into inside heating chamber 5, the delivery port
31 are provided with the outlet pipe 311 extended upwardly into inside heating chamber 5, and the water inlet end of outlet pipe 311 is close to top plate 2, it is ensured that heating
The water of chamber 5 initially enters the bottom of heating chamber 5 again gradually upwards, and the water of heating chamber 5 is by sufficiently heating just arrival outlet pipe
311。
Further, the top plate 2 includes the upper convex portion 23 at middle part, is arranged on the ring part 24 of the bottom of convex platform 23, institute
State steam port 22 to be arranged in upper convex portion 23 and positioned at the side of upper convex portion 23, the water inlet 21 is located on ring part 24.
Further, it is provided with to be provided with bottom plate 62, bottom plate 62 on the base 3 and cartridge heater 1 is enclosed in inside
Double temperature controllers for detecting the temperature of heating chamber 5 are provided with shell 63, shell 63(It is not drawn into figure), it is provided with shell 63
Mounting seat 631 for installing temperature controller, bottom plate 62 is fabricated by by stainless steel 430, is fixed by welding on cartridge heater 1.
Further, the bottom of base 3 is provided with fixed seat 61, and fixed seat 61 is die casting aluminium coffee fixed seat.
The coffee machine of this storage water heater heating, including foregoing storage water heater heater 73, storage water heater heater 73 are intake
Mouthfuls 21, which are connected with water feed apparatus, delivery port 31, is connected with discharging device, steam port 22 and is connected with foam device.
Further, the water feed apparatus is connected with water tank 71, is set between the storage water heater heater 73 and water tank 71
It is equipped with the safety valve 74 for pressure release.
Further, the water feed apparatus includes being sequentially connected with the water inlet 21 of storage water heater heater 73 and constituting water inlet
The RO membrane filtration modules of path(It is not drawn into figure), water pump 72, PP cotton filter assemblies(It is not drawn into figure), RO membrane filtration modules,
PP cottons filter assemblies can fall the contaminant filter in water.
Further, the discharging device includes being sequentially connected with the delivery port 31 of storage water heater heater 73 and constituting water outlet
Outlet valve 81, the brewing filter 82 of path, final coffee are exported in coffee cup 83.
Further, the foam device includes being sequentially connected with the steam port 22 of storage water heater heater 73 and constituting foaming
Steam valve 91, the foaming mouth 92 of path, final milk foam are transported in foaming rotor 93.
Specific works step:
1st, water pump 72 draws water into storage water heater heater 73 from water tank 71, produces hot water by the heating of thick film heating device 4, passes through water
The pressure that pump 72 is produced, opens outlet valve 81, it is 5.5-7.5bar that outlet valve 81, which opens pressure, hot water is reached brewing filter
82, brewing filter 82 is placed with ground coffee in advance, and high-pressure water heating, which is quickly quenched, takes coffee.
2nd, foam flow, when the heating of storage water heater heater 73 makes liquid therein produce a large amount of high steams, manually
Steam valve 91 is opened, high steam enters foaming mouth 92, by the mouth 92 that foams into bubble structure, makes milk mixed at a high speed with vapours
Close, so as to reach frothing milk.
3rd, pressure release flow, when respectively outlet is blocked due to abnormal condition for storage water heater heater 73, due to water pump 72
The pressure produced when pressure and storage water heater heater 73 heating of generation, pipeline is there may be leakage, to prevent dangerous generation,
Now safety valve 74 can be automatically opened up, and it opens pressure in 14-16bar, makes water under high pressure reflow tank 71 again.
Above-described embodiment is the preferred scheme of the present invention, and the present invention can also have other embodiments.The technology of this area
