Specific embodiment

The present invention is made with reference to Fig. 1-Fig. 4 discussed in further detail：

A kind of coffee machine, including casing 10 and top cover 20, is provided with brew chamber 30 in the inner chamber of casing 10, brew chamber 30 Bottom is provided with heating unit, and the top of brew chamber 30 is provided with for placing the filter powder box 40 of ground coffee, the inner chamber of casing 10 In be additionally provided with drainage unit 50, drainage unit 50 guide liquid circulate between brew chamber 30 and filter powder box 40 miscible plus Heat increases the concentration of coffee.Miscible adding is circulated between brew chamber 30 and filter powder box 40 using the guiding of drainage unit 50 liquid Heat increases the concentration of coffee, and by controlling the time that heats, powder of gradually infusing coffee slowly discharges the concentration of coffee, obtains many The coffee of concentration is planted, the requirement of people is met.

Used as the preferred version of the present invention, drainage unit 50 includes the mozzle 51 of vertical direction arrangement, mozzle 51 Upper end extends upwardly to the lower end that the top of filter powder box 40, lower end extend downward brew chamber 30, and the lower end of mozzle 51 is arranged There is check valve 52, the conducting direction of check valve 52 is the direction that fluid is flowed from brew chamber 30 into mozzle 51.Check valve 52 effect is to make liquid flow into mozzle 51 from brew chamber 30, and can not enter brew chamber 30, water conservancy diversion from mozzle 51 Liquid in pipe 51 is entered in brew chamber 30 after flowing out the ground coffee slowly brewed in filter powder box 40 from upper end.

In order to realize that liquid can only flow into the purpose of mozzle 51 from brew chamber 30, described check valve 52 includes pot cover shape Shell 521, the opening direction of shell 521 downwards, hole that mozzle 51 is opened up through in the middle part of shell 521 company fixed thereto Connect, around hole, uniformly offer inlet opening 522, at the inner side end of shell 521, be provided with the plastic cement for covering inlet opening 522 Pad 523.In brew chamber 30, the pressure of liquid can be such that plastics rubber cushion 523 separates with the generation of inlet opening 522, make liquid enter shell 521 inner side, the heated unit heating of liquid are overflowed in the filter powder box 40 on top by mozzle 51, if the concentration of coffee Just, just stop heating, liquid just stops overflow, if the concentration of coffee not enough, continues to heat, liquid continues overflow and brews Ground coffee in the filter powder box 40 on top.

Further, brew chamber 30 is overall cylindrical, extends downwardly step-like water storage tank 31 in the middle part of cylinder bottom, single Notch or cell wall to outer wall and the water storage tank 31 of the shell 521 of valve 52 is tightly connected with merging composition, and heating unit encloses and is located at Around water storage tank 31.Shell 521 is tightly connected with water storage tank 31, it is ensured that the one-way performance of check valve 52, heating unit are enclosed and be located at Around water storage tank 31, the liquid that rapidly can heat in water storage tank 31 makes its overflow infuse coffee powder, again can be to brew chamber Liquid in 30 is heated, and in Fig. 3, the direction of arrow is the direction of current.

Filter powder box 40 includes that the middle part of the main body box 41 and discoid lid 42, main body box 41 and lid 42 of cylindrical shape is equal The through hole passed through for mozzle 51 is offered, the lower end of main body box 41 constitutes spacing matching somebody with somebody with the back-up ring 511 of setting on mozzle 51 Close, on the barrel of main body box 41, be provided with spacing collar 411,33 structure of threaded block arranged on spacing collar 411 and 30 inwall of brew chamber Aperture is evenly distributed with the bottom surface of spacing cooperation, main body box 41 and lid 42.Enough ground coffees are put into filter in advance In powder box 40, liquid enters filter powder box 40 through mozzle 51, flows back to brew chamber 30 again through aperture after powder of infusing coffee, and so circulates Brewing increases the concentration of coffee, and the diameter of aperture can not be too big, it is ensured that while under liquid flow, can filter in ground coffee again A little particles, in order to avoid affect the mouthfeel of coffee.

In order to remove the impurity in liquid, to protrude out to and filter cotton 53 is arranged with 51 mouth of pipe of mozzle above lid 42, Convex tendon 421 is provided with the outer rim of lid 42, and convex tendon 421 is matched somebody with somebody with the barrel of main body box 41 and merges supportive body box 41.Filter pulp 53 After using a period of time, can change.

Liquid in water storage tank 31 completely can not possibly be gone out in overflow, after have including certain liquid residue, under casing 10 Side is provided with base 60, offers the drainage channel 61 of vertical direction insertion, the upper end of drainage channel 61 and punching in the middle part of base 60 The water storage tank 31 of bubble chamber 30 is communicated, lower end is provided with pipe plug.Pipe plug is opened, the liquid in water storage tank 31 passes through 61 row of drainage channel Go out, be easy to clean water storage tank 31, it is to avoid blocking.

Further, the upper end port of casing 10 is socketed with and encloses set 70, has been disposed radially at the upper port of brew chamber 30 Lug 32, lug 32 are constituted with the groove 71 for enclosing setting on 70 madial walls of set through after casing 10 and are engaged by clamping.Enclose setting for set 70 Put and be easy to coordinate with top cover 20.

In order to ensure that coffee machine is operationally a closed environment, top cover 20 with enclose the positions that set 70 contacts be provided with close Seal 21.

For the convenience of the users observation coffee machine in coffee amount and conveniently connect coffee, be provided with casing 10 and brew Delivery port 12 and the liquid level charactron 13 of vertical direction arrangement that room 30 communicates, delivery port 12 are located at the hypomere of brew chamber 30.
