The specific embodiment
Below in conjunction with the accompanying drawing among the utility model embodiment, the technical scheme among the utility model embodiment is clearly and completely described, obviously, described embodiment only is the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment that obtains under the creative work prerequisite, all belong to the scope of the utility model protection.
As shown in Figure 1, a kind of speech prompting system for coffee machine of the present utility model, the signal feedback device that comprises main control substrate 1, is used for responding to the sensing element of each work state information of coffee machine and is used for each work state information of output coffee machine, sensing element and signal output apparatus are electrically connected with main control substrate 1 respectively; Signal feedback device comprises for the OLED screen 2 that shows signal and is used for the loudspeaker 3 of suggestion voice signal.
Sensing element comprises the touch switch 4 for detection of coffee machine water storage tray rigging position, temperature sensor for detection of temperature, water level switch 6 for detection of coffee machine water volume in water tank information, flowmeter 7 for detection of the coffee machine inside water yield and water flow velocity, for detection of the detecting contact 8 of the inner water yield of coffee machine water storage tray, be used for the ultramagnifier that induction motor changes the powder situation.In the present embodiment, temperature sensor is NTC thermistor 5.Ultramagnifier is light blocking inductor 9.
Main control substrate 1 is the maincenter of whole system, is responsible for acknowledge(ment) signal and each sensing element of control, points out by OLED screen 2 and loudspeaker 3.
Touch switch 4 is installed on the position of full-automatic coffee machine water storage tray assembling, when water storage tray when bringing out, touch switch 4 will be in the state of opening, this moment, main control substrate 1 can obtain the information that a water storage tray has been removed, at this moment can show on the OLED screen 2 that " wishing the dress water storage tray good health " main control substrate 1 meeting meanwhile play out by loudspeaker 3: the voice of " do not sense water storage tray, wish the dress water storage tray good health " advance to show.
NTC thermistor 5, the temperature sensitive member that a kind of sensitivity is very high, be installed in the inside heating system of coffee machine, its objective is the temperature of calandria is responded to, at any time feed back the temperature conditions of calandria, when because some abnormal operations are when making that the temperature of calandria surpass to limit numerical value, can show on the OLED screen 2 " temperature is too high " meanwhile main control substrate 1 can play out by loudspeaker 3: the voice of " the present temperature of your coffee machine is too high, and please wait a moment operates again " advance to show.
Water level switch 6 is magnetic reed switch, a kind of switch that can the induced magnetism signal, be installed on the water tank back, be used with a magnetic force ball float in the water tank, water level switch 6 can be sensed the residing position of present ball float at any time, cross when low when the water yield of coffee machine water tank, can show on the OLED screen 2 " please with the water tank topped up with water " meanwhile main control substrate 1 can play out by loudspeaker 3: the voice of " your coffee machine water shortage is please in time filled it up with water tank " advance to show.
Flowmeter 7 can be responded to the water yield and the flow velocity of water, is installed on the source of the inner water circuit system of coffee machine, gives main control substrate 1 with signal feedback.When the discharge of coffee machine can't satisfy coffee extracted because of some unusual conditions, can show on the OLED screen 2 that " system's lack of water " main control substrate 1 meeting meanwhile play out by loudspeaker 3: the voice of " your coffee machine internal system water shortage; ask the button on the pressing operation panel that system is carried out moisturizing " advance to show, sensing the normal loudspeaker 3 later on of water yield recovery when flowmeter 7 will point out: " your coffee machine has recovered normally, please continue to use.”
Detecting contact 8 is the nonisulated contact of two metals, cooperate the induction shell fragment on the water storage tray to use, what of the inner water yield of induction water storage tray are its function be, when water logging does not have two contacts, two detecting contact meeting conductings, main control substrate 1 can judge whether the water of water storage tray inside is full by the resistance sizes of 8 of two detecting contacts.Can show on the OLED screen 2 that " water storage tray water is full " main control substrate 1 meeting meanwhile play out by loudspeaker 3 if the water yield has expired: the voice of " the inner hypervolia of your coffee machine water storage tray please in time empties " advance to show.Do not cause the contact to continue to fall to lead to if empty the back because the water on the contact is dried, at this moment main control substrate 1 will continue prompting by loudspeaker 3: " would you please take out the hard contact on water storage tray and the wiping water storage tray.”
Light blocking inductor 9 is used for carrying out induction motor is changeed the powder situation, its function is the rotation situation of the blade that one group of Photo Interrupter induction motor by inside drives, and data are fed back to main control substrate 1, main control substrate 1 is again by calculating the corresponding number of turns, and when motor because unusually can't be rotated further the time, can show corresponding fault prompting on the OLED screen 2, as " fault XX " meanwhile main control substrate 1 can play out by loudspeaker 3: the voice of " your coffee machine XX that breaks down; please clean; can't get rid of as fault, would you please to dial the customer service phone and seek advice from " advance to show.
Adopt the beneficial effect of the technical program to be: to adopt speech prompting system that the residing situation of coffee machine is reported timely, make things convenient for user's operation, reduce unnecessary trouble, solved the unclear defective of conventional coffee machine text prompt in the past, point out the user more intuitively, prompting more in time, more efficient, and satisfy the use of any language.
To the above-mentioned explanation of the disclosed embodiments, make this area professional and technical personnel can realize or use the utility model.Multiple modification to these embodiment will be apparent concerning those skilled in the art, and defined General Principle can realize under the situation that does not break away from spirit or scope of the present utility model in other embodiments herein.Therefore, the utility model will can not be restricted to these embodiment shown in this article, but will meet the wideest scope consistent with principle disclosed herein and features of novelty.
