In described attemperater 14, be provided with the second temperature sensor 110, described the second temperature sensor 110 is for the temperature of sensing attemperater 14 interior hot water.Described attemperater 14 is also connected with storage tank 17 by water pipe, and on described water pipe, is connected with the 3rd magnetic valve 115.In described attemperater 14, be provided with the second liquid level sensor 105, in described storage tank 17, be provided with the 3rd liquid level sensor 106.Described refrigeration water tank 3 is directly connected with cold water faucet 4.On described attemperater 14, be also connected with a blast pipe 16, one end of described blast pipe 16 is connected with attemperater 14, the other end of described blast pipe 16 is connected with atmosphere, and the one end being connected with atmosphere on described blast pipe 16 is also provided with the 4th magnetic valve 116.Described the 4th magnetic valve 116 cuts out at ordinary times, and to improve the heat insulating ability of attemperater 14, in the time that the water of heating water tank 11 is put into attemperater 14, described the 4th magnetic valve 116 is opened, so that the boiling water in heating water tank 11 can be entered in attemperater 14 smoothly.
In present embodiment, described Tip element 119, control module 101, the first liquid level sensor 103, the second liquid level sensor 105, the 3rd liquid level sensor 106, the first magnetic valve 112, the second magnetic valve 113, the 3rd magnetic valve 115, the 4th magnetic valve 116, the first temperature sensor 109, the second temperature sensor 110, three-temperature sensor 111 and flow sensor 107 are all connected with processor 102, for sending a signal to processor 102 or receiving signal from processor 102.In present embodiment, described control module 101 can comprise liquid crystal touch control screen and/or speech recognition sensor, and described liquid crystal touch control screen is for receiving user's touching signals, and described speech recognition sensor is for receiving user's voice signal; Described Tip element 119 can comprise LCDs and/or loudspeaker, and described LCDs is for passing through picture or text prompt user, and described loudspeaker are for passing through auditory tone cues user.Certainly,, in present embodiment, the LCDs of described Tip element 119 can share the liquid crystal touch control screen of control module 101.
Specifically, the water level being sensed in the first water tank 2 when described the first liquid level sensor 103 exceedes preset value, and 102 of described processors are controlled the first magnetic valves 112 and opened, with by the water injection heating water tank 11 in the first water tank 2.In the time that described flow sensor 107 senses water in injection heating water tank 11 and reaches preset value, 102 of described processors control the first magnetic valves 112 and cut out, to stop toward the interior injected water of heating water tank 11.In the time that described the second temperature sensor 110 senses water temperature in attemperater 14 lower than preset value, 102 of described processors are controlled the 3rd magnetic valves 115 and are opened, so that the water in attemperater 14 is injected in storage tank 17.
Described control module 101 is for sending control signal to processor 102, such as heating instruction or refrigeration instruction etc.To further the operation principle of whole intelligent drinking machine be described in more details below:
User is shielded by liquid crystal touch control and/or speech recognition sensor sends control instruction, such as " start ".Control instruction is sent to processor 102 by described control module 101, first described processor 102 compare the liquid level sensing signal from the first liquid level sensor 103 and the first preset value, in present embodiment, be 500ml, in the time judging that liquid level in the first water tank 2 is less than 500ml, described processor 102 points out user by LCDs or loudspeaker, and now the interior water level of the first water tank 2 is too low, cannot open.In the time judging that liquid level in the first water tank 2 is not less than 500ml, 102 instructions of assigning by control module 101 according to user of described processor comprise two kinds of different handling processes: if user need to make whole intelligent drinking machine refrigeration, the refrigerating function that described processor 102 is opened refrigeration water tank 3 is to start to freeze to the water in refrigeration water tank 3.Described processor 102 judges that temperature value and second preset value of received refrigeration water tank 3 inner cold waters from 111 sensings of three-temperature sensor compare, and in present embodiment, described the second preset value is 10 degrees Celsius.When temperature value in judgement obtains refrigeration water tank 3 is greater than the second preset value, described processor 102 control LCDs or loudspeaker prompting user now water freezed.Now, user opens cold water faucet and the normal-temperature water in refrigeration water tank 3 or cold water can be emitted to use.
If user need to make whole intelligent drinking machine heating, described processor 102 continues the water level in the attemperater 14 obtaining from 105 sensings of the second liquid level sensor and the 3rd preset value to compare, in present embodiment, described the 3rd preset value is 500ml.In the time judging that water level in attemperater 14 is not less than the 3rd preset value, now the boiling water in attemperater 14 is enough by LCDs or loudspeaker prompting user for described processor 102, directly quote the boiling water in attemperater 14, now, user opens hot water tap 5 can emit use by the hot water in attemperater 14, and now described processor 102 is controlled the first magnetic valve 112 and kept closed condition, described heating water tank 11 is also in heated condition not.In the time judging that water level in attemperater 14 is less than the 3rd preset value, described processor 102 continues the water level in the storage tank 17 sensing from the 3rd liquid level sensor 106 and the 4th preset value to compare, in the time that the water level in storage tank 17 is not less than the 4th preset value, described processor 102 sends Tip element 118 and points out user need to first process cold boiling water in storage tank 17 can to start heating.In the time that the water level in storage tank 17 is less than the 4th preset value, described processor 102 is controlled the first magnetic valve 112 and is opened, so that the water in the first water tank 2 is entered in heating water tank 11, and control heating water tank 11 simultaneously and start working that the water in heating water tank 11 is heated.
When processor 102 receives (present embodiment while reaching the 5th preset value from the water temperature of the first temperature sensor 109 heating water tank that senses 11 inside that is arranged in heating water tank 11 inside, described the 5th preset value is 95~100 degrees Celsius), described processor 102 is controlled described the second magnetic valve 113 and the 4th magnetic valve 116 in opening, so that the hot water of heating water tank 11 inside is injected to attemperater 14.Now, 102 of described processors continue to repeat above-mentionedly to judge whether the interior water level of attemperater 14 is less than the flow process of the 3rd preset value.
Be positioned at the water temperature of 110 real-time sensing attemperater 14 inside of the second temperature sensor of described attemperater 14 inside, and transmit it to processor 102.The water temperature that judges attemperater 14 inside when described processor 102 is during lower than the 6th preset value (in present embodiment, described the 6th preset value is 30 degrees Celsius), the second magnetic valve 113 controlled by described processor 102 and the 4th magnetic valve 116 is opened, so that the warm water in attemperater 14 is injected to storage tank 17.
In the utility model, above-mentioned processor 102 can adopt STM32 single-chip microcomputer.
Above-mentioned intelligent drinking machine adopts voice, the dual control of touch-screen, seems very convenient; In the time that water level is not enough, automatic alarm does not heat; And adopt attemperater insulation, stop circulating-heating and produce thousand boiling water.
The foregoing is only preferred embodiment of the present utility model; be not limited to the utility model; all within spirit of the present utility model and principle, any amendment of making, be equal to replacement, improvement etc., within all should being included in the scope of the utility model protection.
