temperature controller

5 and 21 of fuses (concrete extraction location is any), and the sgal among Fig. 3 is signal inserted sheet 14

Coffee machine described in the utility model is when water tank has water, can start working, as shown in Figure 2, live wire (ACL), zero line (ACN) are connected respectively to the hot terminal (L inserted sheet 16) and the zero line terminals (N inserted sheet 17) of pcb board group, described pcb board group comprises PCB control panel 6 and the power supply circuit board 7 that connects by data wire 20, and configurable Liquid Crystal Module shows the job information of coffee machine on the PCB control panel 6.The concrete course of work is as follows: when in the water tank 1 water being arranged, start power supply, heat-generating pipe 2 work, the water of water tank is through one-way cock 13 heat-generating pipe of flowing through, flow to hot water outlet 12 by outlet pipe 4 after converting hot water to by heat-generating pipe, hot water outlet 12 makes hot water flow into the lautertuns 11 that is used for adorning coffee powder, and the coffee that filters through superheated water flows in the coffee cup 10 then, till the whole current of process in water tank 1 of making coffee are intact.Under water tank 1 anhydrous situation, heat-generating pipe 2 continues heating, heat-generating pipe 2 is interior owing to there is not water to flow through, surface temperature raises, when being elevated to the preset temperature value of temperature controller 5, temperature controller 5 will be by closure, heat-generating pipe 2 state shift off-states, and will transmit the temperature controller cut-off signal by signal data line 18 and give the sgal inserted sheet this moment.

Among Fig. 3 on the wiring board break-make between inserted sheet L and the OUT by controllable silicon TR1 and relay R EL1 control.TR1 and REL1 are in parallel and concern, when the REL1 conducting, and conducting fully between L and OUT, controllable silicon REL1 becomes the power energising to heat-generating pipe, like this than the confidential power saving of normal coffee (former common drip-type coffee machine, the heat-generating pipe total power of giving of initial work is switched on); When having only the TR1 conducting, press certain percent time conducting between L and OUT.When L and OUT conducting, and temperature controller is when closed, and inserted sheet SGAL and L connect.Inserted sheet SGAL is connected to chip U1 by interlock circuit, when U1 by this electric circuit inspection behind the signal of L, show that L, OUT, SGAL three are in on-state, and temperature is in closure state less than its break-off signal on this moment temperature controller.

In 45 seconds of initial heating, U1 control REL1 is in off-state, and TR1 was by 9: 4 make-to-break ratio work, and this moment, the ratio of heat-generating pipe power on/off also was 9: 4, promptly according to 9/13 power heating.After 45 seconds, chip controls TR1 is in off-state, and REL1 is in on-state, and at this moment, heat-generating pipe is equivalent to a termination zero line, and a termination live wire is in the heating with full power state.When the temperature controller temperature surpassed its rated temperature, temperature controller disconnected, and then SGAL also disconnects with L, and at this moment, chip detection is judged as temperature controller and disconnects less than the L signal, begins to enter keeping warm mode.Chip controls REL1 makes it be in off-state after entering keeping warm mode, by the conducting of certain percent time control TR1.When temperature on the heat-generating pipe dropped to the temperature controller connection, heating circuit was connected by certain percent time, the heat-generating pipe heating; When the heat-generating pipe temperature rose to the temperature controller disconnection, heating circuit disconnected, and heat-generating pipe does not heat.

One of inventive point of the present utility model is: holding wire 18 is drawn in the optional position between temperature controller 5 and fuse 21, and holding wire 18 is connected on the pcb board by signal inserted sheet 14.By the certain procedure setting, the course of work that is achieved as follows:

Step 1, behind the power connection, the PCB control panel sends instruction, makes heat-generating pipe become the power energising by controllable silicon, and when heat-generating pipe was switched on, the water in the water tank flow to the hot-water outlet and locates 12 through water inlet pipe, heat-generating pipe, outlet pipe successively; The main explanation of this some machine works is in earlier stage by becoming the power save energy;

Step 2,20-50 is (time can be preestablished by program) after second, controllable silicon TR1 (Fig. 3) closes automatically, heat-generating pipe is transformed into automatically the state of full power operation by relay R EL1 (Fig. 3), water in water tank has flowed fully, under water tank 1 anhydrous situation, heat-generating pipe 2 continues heating, owing to there is not water to flow through, surface temperature raises in the heat-generating pipe 2, when the temperature value of rising temperature controller 5, temperature controller 5 will turn to off-state by closure state, to transmit the temperature controller cut-off signal by signal data line 18 and give the signal inserted sheet this moment, and this temperature controller disconnects, and process to boil water is finished in expression; When heat-generating pipe disconnects in advance because of the temperature controller that heating and other reason of part causes, and also have in the water tank under the situation of a spot of water, heat-generating pipe 2 is interior owing to there is water to flow through, when surface temperature will be lower than the temperature value of temperature controller 5, temperature controller meeting automatic reclosing has all flowed water residual in the water tank once more;

Step 3, after finishing process to boil water, coffee machine enters keeping warm mode, the PCB master control borad detects whether reset mode of temperature controller, when detecting temperature control closure (being to finish by SGAL) herein, coffee machine will make controllable silicon work become the power energising to heat-generating pipe, disconnect up to temperature controller, this duty that always circulates is finished up to whole insulating process.

On the basis of technique scheme, whenever finish step 1～step 3 one time, then the pcb board memory is made coffee 1 time, and number of times is tired remembers that certain number of times (can set according to actual needs by concrete number of times when the pcb board memory is made coffee, for example, number of times can be 3 times, 4 times, 5 times or more.), will remind user's coffee machine to need to clean by pcb board.

On the basis of technique scheme, when detecting the temperature controller disconnection (being to finish), give signal of PCB control panel herein in the step 2 by SGAL, the PCB control panel will detect the temperature controller duty in 15 seconds:

1: if closed, coffee machine will make controllable silicon work become the power energising to heat-generating pipe, disconnect once more up to temperature controller, will finish whole process to boil water, enter keeping warm mode.

2: if there is not closure, coffee machine is fulfiled whole process to boil water ahead of schedule, enters keeping warm mode.

On the basis of technique scheme, after finishing process to boil water, coffee machine enters keeping warm mode, mode of operation is: detect whether reset mode of temperature controller with the PCB master control borad, when detecting temperature control closure (mainly being to finish) herein by SGAL, coffee machine will make controllable silicon work become the power energising to heat-generating pipe, disconnect up to temperature controller, this duty circulates always, finish up to whole insulating process, pcb board memory is made coffee 1 time, and number of times is tired remembers certain number of times when the pcb board memory is made coffee, and will remind user's coffee machine to need to clean by pcb board.
