  • By rotating the control knob [0044] 30 to a certain working mode to open channel C and simultaneously actuate the pump, water heated by the electric heater enters the T-connecting valve, then the water distributor, finally outflows through channel C to enter the brewing chamber. After brewing, by rotating the control knob 30 to a certain working mode to open channel E, water from the brewing chamber enters the T-connecting valve through the water-feeding opening D. Water flow through the water-feeding opening D opens the relief valve, enters the water distributor, then outflows through channel E, and is collected by the drip tray.
  • Said water distributor assembly and control valve assembly can be used in combination or separately. When they are working in combination, three kinds of working modes can be provided such as close, low pressure and high pressure. When they are working separately, in combination with the brewing accessory and the pressure hold valve, two kinds of working modes can be provided such as low pressure and high pressure [0045]
  • As shown in FIGS. 4[0046] a and 4 b, the brewing room is suitable for accommodating the coffee capsule. Said brewing room includes a drip water inlet and an espresso water inlet.
  • Water from the water reservoir is pumped by the pump, heated by the electric heater, then distributed by the T-connecting valve, guided controlled valve and the water distributor, finally enters the brewing room through drip water inlet or espresso water inlet for brewing coffee. [0047]
  • As shown in FIG. 5, an espresso coffee brewing accessory is loaded which includes an espresso coffee capsule [0048] 3 connected with the espresso water inlet 2, a filter plate 6 installed under the coffee capsule 3, a small pod cover 1 and a pressure limiting check valve consisting of a small pod seat 5, a discharge plug 8 with a spring 9 thereon and a discharge plug cover 10.

The guided control valve 11 is installed under the lower brewing chamber 13, and the small pod cover 1 is installed under the upper brewing chamber 4.
  • After the upper brewing chamber [0049] 4 is locked, the drip coffee control lever 25 is pressed down by the small pod seat 5. Then, channel A is opened by the guided control valve and channel B is closed. By rotating the control knob 30 to a certain working mode to actuate the pump, water heated by the electric heater enters the brewing chamber via the espresso water inlet and espresso coffee is made. Said pressure limiting check valve keeps the pressure within the brewing chamber at the range of 8-10 BAR when brewing espresso coffee.
  • As shown in FIG. 6, a drip coffee brewing accessory is loaded which includes a drip coffee capsule [0050] 17 connected with the drip coffee inlet 14, a big pod seat 15 installed under the upper brewing chamber 4, a big pod intermediate seat 16 installed under said big pod seat 15, a big pod elastic compression seat 18 under said drip coffee capsule 17, and a big pod spring 19 installed at the bottom of said big pod elastic compression seat 18.
  • After the upper brewing chamber [0051] 4 is locked, the drip coffee control lever 26 is pressed down by the big pod seat 15. Then, channel B is opened by the guided control valve and channel A is closed. By rotating the control knob 30 to a certain working mode to actuate the pump, water heated by the electric heater enters the brewing chamber via the drip water inlet and drip coffee is made.
  • FIGS. 7[0052] a, 7 b, 7 c and 7 d show the brewing room suitable for accommodating a coffee pod or coffee powder or a tea pod. Said brewing room includes a water inlet 40, a piston 48, a water inlet plug 43 installed under said water inlet 40 and within the inner hole of said piston 48, a guided shaft 45 with a guided shaft spring 46 mounted thereon, and a V-ring 47 mounted on said piston 48; said piston 48 can move up and down by compressing said guided shaft spring 46 along said guided shaft 45. Water from the pump is heated by the electric heater, and distributed by the water distributor and the T-connecting valve, finally, enters the brewing chamber via the water inlet 40 for brewing coffee.
  • A pressure hold valve [0053] 39 is also provided, when it is mounted, the pressure inside the brewing chamber is maintained at 8-10 BAR, which is suitable for brewing espresso coffee. When it is not mounted, the pressure inside the brewing chamber is at 0-2.5 BAR, which is suitable for brewing drip coffee or tea.
  • FIGS. 7[0054] a, 7 c, and 7 d show the brewing chamber when an espresso coffee brewing accessory is loaded, which includes espresso coffee pod or espresso coffee powder 37, filter plate 38 and pressure hold valve 39.
  • FIGS. 7[0055] b, 7 c, and 7 d shows the brewing chamber when a drip coffee brewing accessory is loaded, which includes a filter plate 38, drip coffee pod or drip coffee powder 41.
  • After loading the brewing accessory, close the cover assembly [0056] 100, rotate the control knob 30 to open channel C and actuate the pump. Water from the water reservoir 600 enters the T-connecting valve through the pump, and outflows through channel C of the water distributor 900. Then, water enters the piston 48 from the periphery of the water inlet plug 43 via the water inlet 40. The piston 48 moves downwards to the brewing accessory by compressing the guided shaft spring 46 along the guided shaft 45, and thus, with the aid of an O-shaped ring 49, a tightly sealed brewing chamber is formed. When the piston 48 reaches the compression position, the inlet plug 43 is blocked by the piston head 44 and will not move downwards along with the piston 48. Then, the inlet plug 43 and the piston 48 is no longer in the sealing status, water enters the brewing accessory through the inner hole of the piston 48, and thus, the espresso coffee, drip coffee or tea is made. After brewing, rotate the control knob 30 to shut off the pump, to open channel E and the relief water loop. The piston 48 moves upwards along the guided shaft 45 under effect of the spring 46, then the water plug 43 and the piston 48 are in the sealing status, the water within the piston 48 is forced to return to the T-connecting valve along the water-feeding opening D, enters the water distributor 900 via the water discharge channel E, and outflows into the drip tray. After that, the cover assembly 100 can be opened, the brewing accessory can be taken out, and thus the brewing is completed.
  • Said water reservoir assembly [0057] 600 may be replaceable or fixed. A water injection port 300 is installed at the back of the water reservoir, which may be used as a handle as well. Cold water may be filled by opening the water reservoir cover, or through the water injection port without opening the water reservoir cover.
  • Said drip tray assembly [0058] 700 is located below the brewed coffee outlet and is detachably connected with the base assembly 800, so as to be easy for detachment and clean.
