Fig. 2 is the schematic flow sheet of household electrical appliance liquid cooling heat radiation system control method embodiment one of the present invention, Fig. 3 A is the structural representation of liquid cooling heat radiation system in the embodiment of the present invention one, and Fig. 3 B is liquid cooling heat radiation system structural representation in electromagnetic oven in the embodiment of the present invention one；nullWherein，Liquid cooling heat radiation system provided by the invention specifically can be applied in electromagnetic oven (as shown in Figure 3 B)、In the household electrical appliance such as electric baker，It is mainly used to household electrical appliance are dispelled the heat，Wherein，In the present embodiment，Liquid cooling heat radiation system includes control unit (not shown) and liquid-cooling heat radiation unit，As shown in Figure 3，Liquid-cooling heat radiation unit includes: water tank 60、At least one water pump 100、Temperature sensor 501、Fin 50 and drum 40，Wherein，Temperature sensor 501 is for detecting fin 50 and at least one of temperature of drum 40 and the temperature value detected being sent to control unit，Concrete，The quantity of temperature sensor 501 can be one can also be two，And temperature sensor 501 can be arranged on fin 50，Can also be arranged on drum 40，In the present embodiment，It is equipped with fluid flow paths in fin 50 and drum 40，And water tank 60、Water pump 100、Fin 50 and drum 40 constitute at least one coolant closed circuit，In the present embodiment，Control unit specifically can be arranged on the wiring board 80 of household electrical appliance，And control unit and water pump 100 and temperature sensor 501 are electrically connected，Wherein，In order to reduce the power consumption of water pump in liquid cooling heat radiation system and avoid water pump to produce extra heat owing to being constantly in duty，In the present embodiment，Concrete control method comprises the steps:
Step 101, control unit obtain fin and at least one of temperature of drum by temperature sensor, and judge that whether the temperature value got is more than the first preset temperature value.
In the present embodiment, control unit can only obtain the temperature of fin 50 by temperature sensor 501, or only obtain the temperature of drum 40, or the temperature both having obtained fin 50 also obtains the temperature (namely getting two temperature values) of drum 40, after control unit gets temperature value, will judge that whether the temperature value obtained is more than the first preset temperature value, wherein, in the present embodiment, first preset temperature value can be 30 °, namely judge that whether the temperature value obtained is more than 30 °, it should be noted that, when control unit gets two temperature values (temperature value of fin and drum), then two temperature values are all judged with the first preset temperature value.
In the present embodiment, when control unit obtains fin and at least one of temperature of drum by temperature sensor 501, specifically can obtain fin and at least one of temperature of drum in real time, or obtain fin and at least one of temperature of drum according to cycle regular hour.
In the present embodiment, concrete, if only getting a temperature value, then directly judge that whether this temperature value obtained is more than the first preset temperature value, if getting two temperature values, then judging whether two temperature values have a temperature value more than the first preset temperature value, if two temperature values having a temperature value more than the first preset temperature value, then starting to perform step 102.
If one of them temperature value of step 102 is more than the first preset temperature value, then control unit controls water pump with the first rotating speed startup optimization, takes away the heat of drum and fin to drive the coolant in water tank to start the cycle in coolant closed circuit.
nullIn the present embodiment，If have a temperature value more than the first preset temperature value in the temperature obtained，Control unit controls water pump 100 with the first rotating speed startup optimization，Namely when the temperature value of drum 40 and fin 50 all gets，If a temperature value in drum 40 and fin 50 is more than 30 °，Then water pump 100 just starts startup optimization，Wherein，When two temperature values there being a temperature value more than the first preset temperature value，Another temperature value can more than the first preset temperature value，Might be less that the first preset temperature value，Such as Fig. 3，When water pump 100 startup optimization，Coolant in water tank 60 enters in the fluid flow paths in fin 50 and drum 40 under the pump action of water pump 100，Coolant flows in water tank 60 after drum 40 and fin 50 are cooled down，Namely under water pump 100 acts on，Coolant in coolant closed circuit starts the cycle over，Thus the heat that drum 40 and fin 50 produce is taken away.Wherein, in the present embodiment, the first rotating speed is specifically as follows the rotating speed of the 2/3 of water pump 100 full speed, and namely water pump 100 brings into operation but not to run at full speed, so can reaching the thermolysis to drum 40 and fin 50, the noise that is relatively low and that produce of power consumption simultaneously is less.
Wherein, when getting a temperature value (i.e. the temperature value of drum 40 or fin 50), and this temperature value less than the first preset temperature time, or when get two temperature values (temperature of drum 40 and fin 50) are both less than the first preset temperature value, namely the arbitrary temperature value got is both less than the first preset temperature value, then control unit control water pump 100 is out of service, and namely water pump 100 is not operated, now, the coolant in coolant closed circuit does not flow.
In the present embodiment, by control unit according to the temperature value got more than the first preset value time, control water pump 100 with the first rotating speed startup optimization, during less than the first preset value, control water pump 100 out of service, which decrease the power consumption of water pump 100 so that the power consumption of household electrical appliance reduces.
Further, after step 102, the heat produced along with household electrical appliance increases, the temperature of drum 40 or fin 50 can constantly rise, so also needing to continue the temperature got is judged again, Fig. 4 is the another schematic flow sheet of household electrical appliance liquid cooling heat radiation system control method embodiment one of the present invention, as shown in Figure 4, specifically also comprises the steps:
Whether the temperature value that step 103, judgement get is more than the second preset temperature value.
In the present embodiment, water pump 100 is with after the first rotating speed startup optimization, drum 40 and fin 50 are dispelled the heat by the coolant in coolant closed circuit, but it is as household electrical appliance to work for a long time, more heat can be produced, the temperature of drum 40 can constantly rise, and temperature value and the second preset temperature that now real-time the or a certain cycle is got by control unit judge, it is judged that whether the temperature value got is more than the second preset temperature value.
Concrete, if only getting a temperature value (i.e. the temperature of drum 40 or fin 50), then directly judge that whether this temperature value obtained is more than the second preset temperature value, if getting two temperature values, then judge whether two temperature values have a temperature value more than the second preset temperature value, if the temperature got having a temperature value more than the second preset temperature value, then perform step 104.
If one of them temperature value of step 104 is more than the second preset temperature value, then control unit controls water pump with the second rotating speed startup optimization, so that the flow velocity that the coolant in water tank is in coolant closed circuit is accelerated.
nullIn the present embodiment，If judging, the temperature value (temperature of drum 40 or fin 50) got is more than the second preset temperature value，Or get two temperature values there is a temperature value more than the first preset temperature value，As long as namely one of them temperature value is more than the second preset temperature value，Then control unit just controls water pump 100 with the second rotating speed startup optimization，Wherein，Second preset temperature value is more than the first preset temperature value，Second preset temperature value is specifically as follows 50 °，Such as，If the temperature value of drum 40 is more than 50 °，Or the temperature value of fin 50 is more than 50 °，Or one of them temperature value in drum 40 and fin 50 is more than 50 °，Then water pump 100 all runs with the second rotating speed，Second rotating speed is more than the first rotating speed，Wherein，Second rotating speed can be at full speed，Namely water pump 100 is to run at full speed.
It should be noted that, if the temperature value got is more than the first preset temperature value, but during less than the second preset temperature, then water pump still runs with the first rotating speed, namely need not necessarily start to perform step 104 after step 103 and can perform step 102, and, nor is it necessary that after above-mentioned steps 102 and start to perform step 103 and step 104, step 101 and step 103 can be performed simultaneously, then step 102 or step 104 are according to circumstances performed again, or after step 104 performs, then step 101 and step 102 can also be performed.
In the present embodiment, when one of them temperature value in drum 40 and fin 50 is more than 30 °, 100 water pumps run with the first rotating speed, when one of them temperature value in drum 40 and fin 50 is more than 50 °, water pump 100 then runs with the second rotating speed, wherein the first rotating speed is less than the second rotating speed, the power consumption so making water pump 100 decreases, compared with being constantly in duty with water pump in prior art 100, the present embodiment significantly reduces the power consumption of water pump by above-mentioned control method so that the lower power consumption of household electrical appliance.
Embodiment two
Fig. 5 is the schematic flow sheet of liquid cooling heat radiation system control method embodiment two of the present invention, Fig. 6 is the structural representation of liquid cooling heat radiation system in the embodiment of the present invention two, in the present embodiment, as shown in Figure 6, the first coolant closed circuit and the second coolant closed circuit is included when coolant closed circuit, and first coolant closed circuit by the first water pump 101, water tank 60 is connected with fin 50 composition, second coolant closed circuit is by the second water pump 102, water tank 60 be connected with drum 40 composition time, now, as shown in Figure 5, the control method of liquid cooling heat radiation system comprises the steps:
Step 201, control unit obtain the temperature value of fin and drum respectively by temperature sensor, and judge that whether the temperature value of fin and drum is more than the first preset temperature value.
In the present embodiment, owing to drum 40 and fin 50 are on different coolant closed circuits, wherein, fin 50 is for dispelling the heat to the wiring board 80 in household electrical appliance, so in order to ensure that the heat on drum 40 and fin 50 is pulled away in time, in the present embodiment, control unit obtains drum 40 and the temperature value of fin 50 respectively, concrete, temperature sensor 501 can be set on drum 40, being also provided with temperature sensor 501 on fin 50, such control unit can obtain the temperature of drum 40 and fin 50 simultaneously.
It should be noted that, when step 201 performs, if the temperature of fin 50 and drum 40 is all higher than the first preset temperature value, then performing step 202a, if the temperature of fin 50 is more than the first preset temperature value, the temperature of drum 40 is less than the first preset temperature value, then perform step 202b, if the temperature of drum 40 is more than the first preset temperature value, the temperature of fin 50 less than the first preset temperature value, then performs step 202c.
If the temperature value of step 202a fin and drum is all higher than the first preset temperature value, then control unit controls the first water pump and the second water pump all with the first rotating speed startup optimization.
In the present embodiment, if the temperature of fin 50 and drum 40 is all higher than the first preset temperature value, then control unit controls the first water pump 101 and the second water pump 102 all with the first rotating speed startup optimization, coolant in such first coolant closed circuit and the second coolant closed circuit starts the cycle under the pump action of the first water pump 101 and the second water pump 102, so that the temperature of drum 40 and fin 50 reduces.
If the temperature value of step 202b fin is more than the first preset temperature value, the temperature value of drum is less than the first preset temperature value, then control unit controls the first water pump with the first rotating speed startup optimization, controls the second water pump out of service.
In the present embodiment, due to two loops that the first coolant closed circuit and the second coolant closed circuit are independent, therefore, when the temperature value of fin is more than the first preset temperature value, control unit controls the first water pump 101 and runs with the first rotating speed so that the first coolant closed circuit starts the cycle over.Owing to the temperature value of drum 40 is less than the first preset temperature value, namely the temperature of drum 40 is relatively low, it is not necessary to entering heat radiation, therefore, it is out of service that control unit controls the second water pump 102, and the second water pump 102 is in non-duty.When this avoid one of them temperature value more than the first preset temperature, the problem that two water pumps all cause power consumption to raise so that the first rotating speed runs.
If the temperature value of step 202c drum is more than the first preset temperature value, the temperature value of fin is less than the first preset temperature value, then control unit controls the second water pump with the first rotating speed startup optimization, controls the first water pump out of service.
In the present embodiment, when the temperature of drum 40 is more than the first preset temperature value, then control the second water pump 102 with the first rotating speed startup optimization, when the temperature of fin 50 is less than the first preset temperature value, then control the first water pump 101 out of service.
