The specific embodiment
Please refer to shown in Figure 1ly, is according to specific embodiment of the invention combined type drying and washing machine system perspective view.Combined type drying and washing machine system 1 comprises washing machine 10, washing machine control system 11, washing machine heating pipe 12, dryer 20, dryer control system 21 and dryer heating tube 22.The washing process of washing machine control system 11 control washing machines 10, the drying course of dryer control system 21 control dryers 20.In conjunction with shown in Figure 2, combined type drying and washing machine system 1 also comprise the dryer power-line plug 2 that is positioned at dryer 20 rear ends, can be for external gang socket 3 and the washing machine power-line plug 4 that is positioned at washing machine 10 rear ends.Gang socket 3 can be arranged on the rear end of dryer 20, also can be arranged on the rear end of washing machine 10.When whole system is used in combination, washing machine power line 4 is inserted in the gang socket 3, thereby realize being electrically connected.Certainly, washing machine 10 and dryer 20 also can independently use, and only corresponding washing machine power-line plug 4 and dryer power-line plug 2 access external power supplys need be got final product.Dryer power-line plug 2, gang socket 3 and washing machine power-line plug 4 meet the GB1002 standard.
In conjunction with Fig. 3 and shown in Figure 4, be control whole system operation electric current, also comprise the power management module 23 of control system electric current in the dryer control system 21, certainly, power management module 23 also can be arranged in the washing machine control system 11, and washing machine heating pipe 12 is controlled.Being arranged in the dryer control system 21 with power management module 23 is example, and power management module 23 comprises the first control circuit 24 of the operating current of adjusting dryer heating tube 22.Preferably, first control circuit 24 comprises first relay 27 of connecting with dryer heating tube 22, the diode 26 that is in parallel with dryer heating tube 22 and second relay 28 of connecting with diode 26.When second relay, 28 closures, promptly dryer heating tube 22 is carried out half-wave control, to realize that power reduces by half.Accordingly, the second control circuit 14 that comprises 12 work of control washing machine heating pipe in the washing machine control system 11.Preferably, second control circuit 14 comprises the 3rd relay 17 that is in series with washing machine heating pipe 12.When the 3rd relay 17 disconnects, promptly stop washing machine heating pipe 12 is powered, washing machine heating pipe 12 promptly stops heating.In other embodiments, if power management module 23 is located in the washing machine control system 11, then second control circuit 14 comprises diode and the relay that is in parallel with washing machine heating pipe 12, thereby can carry out half-wave control to washing machine heating pipe 12.
Be further logic control system operating current, power management module 23 also comprises sample circuit 5, analog-digital commutator 6 and comparison means 7, comprises the sampling resistor 8 of acquisition system operating circuit electric current in the sample circuit 5.When being in system works pattern following time, be that washing machine power-line plug 4 is when inserting in the dryer gang sockets 3, connect power supply this moment starts working washing machine 10 and dryer 20, if first relay 27 and the 3rd relay 17 closures, second relay 28 is opened, washing machine heating pipe 12 and dryer heating tube 22 are in normal operating conditions simultaneously, the system works electric current of combined type drying and washing machine system 1 exceeds general trouble free service electric current possibly at this moment, thereby may cause potential safety hazard.Power management module 23 carries out analog-to-digital conversion by analog-digital commutator 6 with the current value that is collected then, and compares with predefined trouble free service electric current by comparison means 7 by sample circuit 5 acquisition system operating currents.The trouble free service current value can be changed according to actual conditions, satisfies the different requirement of client in different regions.When the operating current of judging actual acquisition was higher than the trouble free service electric current, 23 closures of power management module, second relay 28 was to carry out half-wave control to dryer heating tube 22.If the system works electric current that this moment, power management module 23 collected by sample circuit 5 is still greater than the trouble free service electric current, then disconnect first relay 27, dryer heating tube 22 is quit work, thereby guarantee that the system works electric current is within the trouble free service current range.Washing machine 10 program for washing finish or washing machine heating pipe 12 heating finish and work as, and the whole system operation electric current must descend.Energy supply control module 23 makes first relay, 27 closures when receiving the feedback signal of sample circuit 5, second relay 28 is opened, and dryer heating tube 22 obtains normal power supply at this moment, continues heating.If detect the system works electric current greater than the trouble free service electric current this moment, then closed second relay 28 is to carry out half-wave control to dryer heating tube 22.
Therefore, combined type drying and washing machine system according to the specific embodiment of the invention, can carry out logic to the system works electric current in real time by power management module judges, and the operating current of control dryer heating tube or washing machine heating pipe is controlled separately according to judged result, both heating tube can be disconnected fully, also can adopt half-wave control, thereby the whole system operating current is reduced within the trouble free service current range.Whole process realizes that by logic control control mode is accurate flexibly, has increased the security of system greatly fully, and having avoided family simultaneously is the expense expenditure of big electric current independent wiring.In addition, in the above-described embodiments, when washing program for washing machine finishes or the washing machine heating pipe heating finishes, energy supply control module can recover the power supply to the dryer heating tube, makes system have higher operating efficiency under the prerequisite of safety utilization of electric power.
Certainly, the above embodiment of lifting only is better embodiment of the present invention, the present invention can also have many other embodiments, for the person of ordinary skill of the art, that is done under instruction of the present invention changes at equivalence of the present invention, must be included in the scope that claim of the present invention advocates.
