The water tank 7 of dress water is set in shell 4.When operation first coffee maker 1, in order to make coffee, water is transported to brew chamber 8 from water tank 7, impels water to flow through some ground coffee beans in brew chamber.The water supply installation that extends to brew chamber 8 from water tank 7 comprises conduit 9, and this conduit can be crooked to small part, and it extends through the heating clamber 10 that wherein is provided with electrical heating elements 11.End at conduit 9 is provided with shower nozzle 12, and shower nozzle is positioned at the roof 13 of brew chamber 8.The roof 13 of brew chamber 8 is the part of removable hood 5.Pump 14 is set in water supply installation to be used for water is discharged to brew chamber 8 from water tank 7.
Fig. 1 has shown that coffee pad 15 is placed on first coffee maker, 1 inside.Coffee pad 15 comprises the envelope that some ground coffee are housed.When operation first coffee maker 1, water is forced to flow through coffee pad 15.In this process, envelope is as filter.Like this, obtain coffee on the interactional basis between the coffee pad 15 in pressure (hydraulic) water and brew chamber 8.
In order to emit coffee, pad support 16 comprises outlet nozzle 18, and a relatively little exit passageway 19 wherein is provided in the bottom of outlet nozzle 18.In addition, first coffee maker 1 comprises that the coffee that outlet nozzle 18 is flowed out is sent to the distributor 20 of cup 2.
When first coffee maker 1 was used to make coffee, the user of coffee maker 1 should be noted that at least one coffee pad 15 is placed in the brew chamber 8, and covered 5 in the closed position.Then, start pump 14, force the water of scheduled volume to flow into brew chamber 8 from water tank 7 through predetermined period.In addition, start electrons heat element 11, make current through heating clamber 10 heating.Hot water is fed to brew chamber 8 by shower nozzle 12.Under the influence of pump 14 effects, the pressure in the brew chamber 8 is increased.
In brew chamber 8, carry out real coffee making process, wherein, the coffee pad 15 of flow of hot water through containing some ground coffee.The coffee that obtains flows to the outlet nozzle 18 of pad support 16 continuously, and flows out brew chamber 8 by exit passageway 19.
The diameter of relatively little exit passageway 19 can be in having only 0.5 to 1.2 millimeter scope.Therefore use first coffee maker 1 many times after exit passageway 19 may block.Under the situation that exit passageway 19 blocks, operate first coffee maker 1, the pressure in the brew chamber 8 increases, the paranormal operating pressure of this pressure.The situation that pressure becomes more and more higher may last till till the scheduled time termination that starts pump 14.But, in case also may first coffee maker 1 comprise that finishing coffee maker 1 operation and/or pressure arrives maximum allowable pressure and make and cover 5 release mechanisms in the closed position.Consider when pressure rises to surpass routine operating pressure, opening brew chamber 8 may be dangerous, because have the danger of the liquid of heat from brew chamber 8 ejections, can wish to exist this release mechanism.For self, the release mechanism of coffee maker 1 can comprise known suitable parts, for example pressure sensor and finish the microcontroller that various functions comprise the function that the detected pressure data of sensor and predetermined pressure data are compared.
Under the situation that exit passageway 19 gets clogged, just in time after the operation that finishes pump 14, pressure in the brew chamber 8 is higher than environmental pressure significantly, because act on and cover 5, the top side of shell 4 and cover 5 and the top side of shell 4 between high frictional force between the sealing device (not showing) that exists, can not place open position with covering 5.Have only the pressure in brew chamber 8 to be reduced to significantly low level, just may unclamp and cover 5.As long as brew chamber 8 keeps closing, the speed that the pressure in the brew chamber 8 reduces is very low, so the very worried wait of user may be with 5 times that place open position and remove pad support 16 and coffee pad 15 from first coffee maker 1 of lid.In order to quicken the process that pressure descends, first coffee maker 1 provides the sliding panel 21 with groove 22, and it is configured to extend through the opening 23 of pad support 16.For clear, Fig. 2 and 3 show sliding panels 21, have wherein described the pad support 16 of first coffee maker 1.
Hereinafter, explain the operation of sliding panel 21 with reference to Fig. 2 and 3.
As shown in Figure 2, at the initial position of sliding panel 21, a part of sliding panel 21 with groove 22 is positioned at brew chamber 8 fully.In this position, the opening 23 of pad support 16 is stopped by sliding panel 21 fully.Yet, when when pulling back sliding panel 21 with respect to pad support 16 and make sliding panel 21 place enable position, this part sliding panel 21 with groove 22 is positioned at opening 23, and wherein said part sliding panel 21 parts are positioned at brew chamber 8, and a part is positioned at brew chamber 8 outsides.Therefore, the part opening 23 in the pad support 16 is empty, and the pressure under the influence of the quite low pressure in brew chamber 8 outsides in the brew chamber 8 descends.The pressure that initial pressure reduction on the opening 23 in the pad support 23 reduces in brew chamber 8 is consistent with the pressure outside the brew chamber 8.In this case, thus the user may place open position to open brew chamber 8 by covering 5.
Thereby placing open position to need to reduce under the situation of the pressure in the brew chamber 8 before opening brew chamber 8 by covering 5, sliding panel 21 is applicable to and produces an opening that limits in brew chamber 8.This opening is small enough to avoid producing the unsafe situation that is associated with generation pressure decline suddenly in the brew chamber 8, and this opening is even as big as reasonably realizing the reduction of brew chamber 8 internal pressures in the time simultaneously.
In case the projecting pressure of described pressure and cover 5 and still be positioned at the closed position in order to reduce the pressure in the brew chamber 8 relatively apace, except the sliding panel 21 with groove 22, can adopt other decompressor.In second preferred embodiment, coffee maker according to the present invention comprises having the valve 24 that regulation is leaked.Hereinafter, described coffee maker also can be known as second coffee maker.
Except decompressor, second coffee maker can be similar with first coffee maker 1 shown in Figure 1.Therefore, not whole in the drawings second coffee apparatus that shows.On the contrary, only shown that part of second coffee maker different with the appropriate section of first coffee maker 1.Especially, only show pad support 16 and relevant valve 24.In Fig. 4, show these parts of second coffee maker when valve 24 is in the closed position, and in Fig. 5, shown these parts of second coffee maker when valve 24 is shown in an open position.
Valve 24 shown in Figure 4 and 5 comprises the dome 25 of a bending and has the center connecting rod 26 of thickening 27.Valve 24 is connected on the pad support 16 by connecting rod 26, and wherein connecting rod 26 extends through the hole of pad support 16, and wherein the thickening 27 of dome 25 and connecting rod 26 is positioned on the another side of pad support 16 separately.Especially, the thickening 27 of connecting rod 26 is positioned at the inside of pad support 16, and dome 25 is positioned at the outside of pad support 16.In the structure of wound hole, the connecting rod 26 of valve 24 extends through this hole, and a plurality of valve openings 28 are set in pad support 16.
In the closed position of as shown in Figure 4 valve 24, on the dome 25 of valve 24, do not exert pressure, and valve opening 28 is closed by dome 25.Yet when pressure produced in brew chamber 8, described pressure was applied on the dome 25 equally by valve opening 28.Under ever-increasing pressure influence, dome 25 distortion becomes the dish on plane almost.In a certain moment of deformation process, dome 25 no longer can be closed by maintaining valve opening 28, produces to leak.In Fig. 5, shown the open position relevant with valve 24.When valve 24 was positioned at open position, valve opening 28 was empty, and this causes the main pressure in the brew chamber 8 to reduce in the similar mode of explanation to device with sliding panel 21 as described above.
Advantageously, the characteristic of selector valve 24 makes valve 24 open when pressure is higher than routine operating pressure.Like this, avoid brew chamber 8 formation leakages when normal running second coffee maker.
Within the scope of the invention, except the sort of type shown in Figure 4 and 5, can use the valve 24 of another kind of suitable type, wherein importantly under the second coffee maker normal operating condition, valve 24 is arranged to for example block at least one valve opening 28, and when the pressure in the brew chamber 8 surpasses predetermined maximum butterfly gate opening 28 not.Therefore, valve 24 can be the pressure-reducing valve of any suitable type.
The third suitable decompressor has been described in Fig. 6 and 7.Especially, Fig. 6 shows the pad support 16 of coffee maker according to the third preferred embodiment of the present invention and relevant decompressor with 7.Hereinafter, described coffee maker also is known as the 3rd coffee maker.Notice that similar with second coffee maker, except decompressor, the 3rd coffee maker can be similar to first coffee maker as shown in Figure 1.Therefore, the same with second coffee maker, all do not show the 3rd coffee maker in the drawings.
In the 3rd coffee maker, the outlet nozzle 18 of pad support 16 comprises two parts,, is fixedly attached to the part 18a on the other parts of pad support 16 that is, and the detachable part 18b that installs.The a certain position of detachable mounting portion 18b between the end 30,31 of leaf spring 29 of outlet nozzle 18 is connected on the leaf spring 29, and wherein an end 30 of leaf spring 29 is connected on the pad support 16, and wherein the other end 31 of leaf spring 29 is not fixed.
In the initial position of as shown in Figure 6 leaf spring 29, the detachable mounting portion 18b of outlet nozzle 18 fixes against the fixed installation part 18a of outlet nozzle 18.Therefore, at the initial position of leaf spring 29, the outlet nozzle 18 of pad support 16 has normal outward appearance, and the initial position of leaf spring 29 is relevant with the normal operating condition of the 3rd coffee maker.Yet, when the not stiff end 31 of leaf spring 29 being exerted pressure and described end 31 pressurizeds of leaf spring 29 during away from pad support 16, the detachable mounting portion 18b of outlet nozzle 18 moves away from fixed installation part 18a, does not therefore hinder the free end of the fixed installation part 18a of outlet nozzle 18.Like this, in pad support 16, obtain an opening that limits.
As the result that the exit passageway 19 of pad support 16 gets clogged, when the pressure in the brew chamber 8 become too high, thereby the user of the 3rd coffee maker can select the free end 31 of leaf spring 29 is applied the power release pressure, and the result opens outlet nozzle 18.User one discharges the free end of leaf spring 29, and under the influence of leaf spring 29 effects, the detachable mounting portion 18b of outlet nozzle 18 just gets back to the original place again.
Within the scope of the invention, for the detachable mounting portion 18b of the outlet nozzle 18 that makes pad support 16 remains on correct position, except leaf spring 29, can use other suitable elastic device, and can adopt other suitable device to offset the effect of elastic device to detachable mounting portion 18b.Employing benefit of leaf spring 29 shown in Fig. 6 and 7 is that the free end 31 of leaf spring 29 can be used to make two parts 18a of outlet nozzle 18, the purpose that 18b separates, and do not need extra element.Opening outlet nozzle 18 needed power can be applied by the user, forces the device of the free end 31 of leaf spring 29 away from pad support 16 when the predetermined maximum level automatically but the 3rd coffee maker also may comprise a pressure that is used for brew chamber 8 in.
The very clear scope of the present invention of those skilled in the art is not the embodiment that is subject to above-mentioned discussion, but does not wherein depart from some corrections of acceptable and the change of the scope of the invention that the accessory claim book limited.
