The specific embodiment
As shown in Figure 1, disclose the cut-away view of the intelligent espresso coffee machine of the present invention, mainly be in the espresso coffee machine 3 or its casing is provided with the members such as steam switch 34 of a power switch 14, a control module 1, a sound wave attention device 16, a display unit 2 and boiler 31, be equiped with a heater 15, a water inlet switch 32, a drainage switch 33 and three not isometric water level probes 11,12,13 in this boiler 31.Wherein:
Sound wave attention device 16 is implemented to can be a music IC circuit or buzzer, accepts the startup or the closing control of control module 1, to send the caution sound in good time.
Water inlet switch 32 can be a magnetic valve, connects control module 1 by power lead, and the control of accepting to drive valve or closing valve; In addition, on easy device, water inlet switch 32 also can be the ball valve of a hand.Water inlet switch 32 is connected with the extraneous supply channel or the pipeline of feed pump, opens valve supply water by automatic or manual and enters in the boiler 31 or close valve and stop to supply water.
Three not isometric water level probes are respectively a high-level probe 11, a middle water level probe 12 and another low-level probe 13, together are set in the boiler 31, and make its end seat be exposed to boiler 31 outsides, in order to connect RCA to control module 1.
In addition, the also configurable cylindrical shell 8 in boiler 31 outsides that the present invention is above-mentioned, as shown in figure 11, utilize water inlet manifold 81 and another drain manifold 82 to be connected between boiler 31 and the cylindrical shell 8, boiler 31 interior water liquid also can be guided in the cylindrical shell 8, present and have identical liquid level phenomenon, and above-mentioned three not isometric water level probes 11,12 and 13 together are arranged in this cylindrical shell 8, so as to the sensed water level state, this also is an application of the present invention, and gives Chen Ming.Because of heater 15 is to be installed in to add hot water liquid in the boiler 31, therefore the fluctuating flow that produces when water boil can't feed through to the water in the cylindrical shell 8 therebetween, can avoid the excessive phenomenon that causes incrustation on the probe of current fluctuation.
Also can have only the independent water level probe 11,12 or 13 that is provided with in three water level probes (as shown in figure 12 in the above-mentioned cylindrical shell 8, with middle water level probe 12 is example), therefore so long as utilize cylindrical shell 8 that at least one water level probe is set, embodiment in all the other two or one boilers that then are arranged at identical liquid level waterline 31 also is an application of the present invention.
By above-mentioned member, go out the water-level control apparatus of espresso coffee machine of the present invention with construction, can carry out the following method that detects the water level in the boiler state automatically by this device, include:
(1) power switch 14 on the unlatching coffee machine enters duty (as shown in Figure 2) to start a control module 1;
(2) use a high-level probe 11, a middle water level probe 12 and a low-level probe 13 together to be arranged on to detect in boiler 31 or (reach) cylindrical shell 8 water position status (Fig. 1 and shown in Figure 11 arranges in pairs or groups), the signal of water position status is passed in the control module 1 carries out the water level identification; And,
(3) make control module 1 judge the heater 15 or the sound wave attention device 16 of opening or closing in the boiler 31, and start the water level indicator light that display unit 2 discloses water position status.
The above-mentioned method that detects water position status has the performing a programme under following four kinds of water position status:
(1) ordinary water level state: when waterline 7 in boiler 31 or (reaching) cylindrical shell 8 floods when contacting low-level probe 13 with middle water level probe 12 simultaneously (as Fig. 3, shown in Figure 4), high-level probe 11 is not touched by water logging, probe can transmit an ordinary water level signal to control module 1, control module 1 is judged startup heater 15 (sound wave attention device 16 is a closed condition at this moment), in order to the water in the heating boiler 31 to vapour pressure that sets or temperature, control module 1 starts display unit 2 announcements simultaneously and lights ordinary water level indicator lamp 22, the user just can push steam switch 34 this moment, is used for making the milk bubble of espresso coffee with acquisition stove inner vapor.In addition, the hot water in the boiler 31 also can be supplied in warm coffee cup or the use of infusing coffee by a hot-water switch.
(2) full water water position status: waterline 71 floods simultaneously and contacts low-level probe 13 in boiler 31 or (reaching) cylindrical shell 8; when middle water level probe 12 and high-level probe 13 (shown in Figure 6) as Fig. 5; probe can transmit a full water water level signal to control module 1; heater 15 is closed in control module 1 judgement; stop the water in the heating boiler 31 immediately; control module 1 also can start sound wave attention device 16 simultaneously and produce the prompting sound; control module 1 also starts display unit 2 announcements simultaneously and lights full water water level indicator light 21; unusual full water problem appears in order to the enforceable operator's of informing appliance arrangement; answer hard stop maintenance 4; inspection is that water inlet switch 32 leaks; or and be that card dirt or other failure cause appear in above-mentioned probe; after pending fault is repaired; but operator just opening water discharge switch 33 carries out draining; water liquid unnecessary in the boiler 13 is discharged, make device return to above-mentioned ordinary water level state.
(3) moisturizing water position status: when the waterline 72 in boiler 31 or (reaching) cylindrical shell 8 only floods when contacting low-level probe 13 (as Fig. 7, shown in Figure 8), probe can transmit a moisturizing water level signal to control module 1, this moment, control module 1 still kept starting the normal heating state of heater 15, sound wave attention device 16 is not activated, control module 1 can 2 announcements of startup display unit light moisturizing water level indicator light 23 simultaneously, disclose and inform that in order to clear water is existing short in operator's boiler 31, should carry out moisturizing 6, at this moment, control module 1 can be opened water inlet switch 32 (magnetic valve), or by the manually opened water inlet switch 32 of user (ball valve), to supply water in the boiler 31 to above-mentioned ordinary water level line states.
(4) lack of water water position status: waterline 73 breaks away from low-level probe 13 simultaneously in boiler 31 or (reaching) cylindrical shell 8; when middle water level probe 12 and high-level probe 11 (shown in Figure 10) as Fig. 9; probe can transmit a lack of water water level signal to control module 1; control module 1 can judgement be closed heater 15; stop the water in the heating boiler 31 immediately; control module 1 also can start sound wave attention device 16 simultaneously and produce the prompting sound; control module 1 starts display unit 2 announcements simultaneously and lights lack of water water level indicator light 24; unusual water shortage problem appears in order to the enforceable operator's of informing appliance arrangement; answer hard stop maintenance 41; whether check has or not drainage switch 33 to leak or other failure cause; after pending fault is repaired; the user just can open water inlet switch 32, and the water in the boiler 31 is added into above-mentioned ordinary water level state.
