Therefore, says when 100 volts drop to 90 volts and the speed of compressor 44 and keep the steady state value of for example per second 100 commentaries on classics that because of decline has taken place for the input voltage of clothes washer-dryer, input current will correspondingly increase in the analogy of the alternating voltage that provides from attaching plug 61.But in the present embodiment, when the input current of the 2nd rectification circuit 59 surpasses 9 ampere-hours, current sensing means 170 will detect this situation, and to micro computer 179 output signals; Micro computer 179 will send instruction to the 3rd converter circuit 57 when detecting input current greater than setting, make the operating rate of compressor 44 be reduced to for example per second 80 commentaries on classics from per second 100 commentaries on classics.Like this, can make the electric current that in the 2nd rectification circuit 59, flows be no more than 9 amperes.
Like this, big electric current can not occur in each component parts in the 2nd rectification circuit 59 and the 3rd converter circuit 57, therefore not worry that its generation is overheated, reliability also can be improved.
(embodiment 3)
Fig. 8 is the partial circuit figure of the clothes washer-dryer among the present invention the 3rd embodiment, wherein, has been put on identical symbol with component part identical among the top embodiment, and has omitted the repeat specification to it.
In Fig. 8, the 3rd converter circuit 57 will be from the DC voltage VDC between input terminal P, the N as out-put supply, and it is identical with the 2nd rectification circuit 59 that illustrated among the top embodiment that concrete circuit constitutes.
Be provided with the rotor 192 that has permanent magnet 191,191a in the compressor 44, and have 3 phase windings 193,194,195.
200 is cooling fan, is used for blowing away cooling air to the component part of the 3rd converter circuit 57 that is by the switch element 111,112,113,114,115,116 that IGBT constitutes, and it is cooled off.In addition, also can cool off, also can cool off other component parts in the 1st converter circuit 55 the 2nd converter circuit 56 clothes washer-dryers such as grade in addition heat generating components such as rectifier cell and reactor etc.
Cooling is provided with in the electric fan 200: the cage rotor 201 identical with the rotor of general use in induction conductivity, be installed in rotary fan 202 and 3 phase windings 203,204,205 on the axle of rotor 201.
In the present embodiment, winding 203,204,205 is reeled by enamel-covered wire and is formed, and the winding 193,194,195 in winding 203,204,205 and the compressor 44 is connected in series respectively.
That is cooling electric fan 200 is connected on the output of the 3rd converter circuit 57 that is connected in series with compressor 44, and each winding current of compressor 44 also supplies in the winding 203,204,205 that cools off in the electric fan 200 simultaneously.
The speed of compressor 44 is high more, and it is big more that the caloric value of the 3rd converter circuit 57 also just becomes.For this reason, in the present embodiment, the electric current identical with the frequency of alternating current in supplying to compressor 44 is provided in each winding of cooling electric fan 200, is used for producing rotating excitation field, and rotor 201 and fan 202 are rotated with the rotating speed near rotating excitation field.Like this, always can access basically with the 3rd converter circuit 57 in the corresponding cooling air quantity of loss heat, thereby carry out extremely reasonably cooling down operation.
At this moment, being input to voltage in the compressor 44 is that the output voltage of the 3rd converter circuit 57 deducts the voltage on the cooling electric fan 200.But electric current is very big because the number of turns of the winding 203,204,205 of cooling electric fan 200 seldom, and voltage is very low, can ignore to the falling quantity of voltages that compressor 44 causes.Like this, both can suppress the increase of number of components, cooling electric fan 200 is worked effectively, the 3rd frequency converter 57 is effectively cooled off, a kind of volume is little, the clothes washer-dryer of low cost of manufacture thereby can provide.
In addition, in the present embodiment, cooling electric fan 200 is that the formation of the induction conductivity by having cage rotor 201 realizes, so even if also be difficult for fault such as generation step-out during the speed generation cataclysm of compressor 44, can realize stable operation.But, also not necessarily must adopt cage rotor here, the form that also can adopt the type that for example has permanent magnet or have inhomogeneous magnetic, can synchronously rotate with rotating excitation field.
In addition, among superincumbent each embodiment, though the rotating shaft 42a of rotating cylinder 42 is level, but rotating shaft is not limited to horizontal direction, rotating cylinder is supporting " uprightly " form of rotation at vertical axis in the time of also can being arranged to for example dewater, perhaps make rotating shaft with respect to horizontal direction tilt about 20～30 degree, with the form of input/taking-up of making things convenient for clothing 41.In addition, for example can also be provided with other mechanical parts such as impeller in the rotating cylinder 42, thereby when laundry, can carry out high efficiency washing.
Comprehensively described, clothes washer-dryer of the present invention carries out high efficiency operation by making each converter circuit, parts can be reached rationally to be shared, thereby reduce body shape and manufacturing cost, therefore, can be useful in the various machinery equipments with a plurality of electrical loads of being controlled by converter circuit.
