Description
Technical field
The utility model relates to a kind of converter plant, relates in particular to a kind of use in washing machine converter plant.
Background technology
Just at present, frequency conversion is more and more admitted by consumers in general from the angle of saving the energy as the current relatively technology in forward position, and country also is suitable support.Present variable-frequency washing machine mostly is single AC level relay step-down module controls in parallel for the control of variable frequency module power supply, thereby whether the logical circuit power of control of conversion module is lower than operate as normal VDD, reaches the purpose of control of conversion module work.
But, the high-pressure side of frequency-variable module has high direct voltage all the time in this case, the logical circuit of frequency-variable module also has dc low-voltage all the time, therefore the logical circuit and the step-down module of frequency-variable module also have power consumption when frequency-variable module is not worked, and come the mode of control switching output that the efficient of Switching Power Supply is decreased by step-down.Considering from the aspect of the safety and the energy, is need be improved.
Summary of the invention
The purpose of this utility model is to overcome the above problem that prior art exists, and a kind of use in washing machine converter plant is provided.
For realizing the purpose of this utility model use in washing machine converter plant, include the device box body, be provided with rectification module in the described device box body, wherein: the output of described rectification module connects the input of Voltage stabilizing module, and the output of described Voltage stabilizing module connects the input of frequency-variable module by the main switch module; Be provided with external path between the output of described rectification module and the input of frequency-variable module, be connected with the auxiliary switch module between the described external path; Be connected with driver module between described main switch module and the auxiliary switch module; At least be provided with a communication port on the described driver module.
Further, above-mentioned use in washing machine converter plant wherein, is connected with PNP triode and relay on the described communication port.
Further, above-mentioned use in washing machine converter plant, wherein, the output of described Voltage stabilizing module is connected into the main switch module by the low-voltage direct path.
Again further, above-mentioned use in washing machine converter plant, wherein, described external path is the high voltage direct current path.
Adopt technical solutions of the utility model, frequency-variable module can all not be in electriferous state all the time.Logical circuit under step-down module and frequency-variable module during the frequency-variable module inoperative does not all have energy consumption simultaneously.Thus, be not only the energy resource consumption of having saved this device, more improved the overall work fail safe of device.
The purpose of this utility model, advantage and characteristics will illustrate by the non-limitative illustration of following preferential embodiment and explain that these embodiment only provide as an example with reference to accompanying drawing.
Description of drawings
Fig. 1 is the organigram of use in washing machine converter plant.
The implication of each Reference numeral is as follows among the figure:
1 device box body, 2 rectification modules
3 Voltage stabilizing modules, 4 main switch modules
5 frequency-variable modules, 6 auxiliary switch modules
7 driver modules, 8 communication port
9 low-voltage directs lead to 10 high voltage direct current paths
Embodiment
Use in washing machine converter plant as shown in Figure 1, include device box body 1, be provided with rectification module 2 in the described device box body 1, its special feature is: the output of described rectification module 2 connects the input of Voltage stabilizing module 3, and the output of Voltage stabilizing module 3 connects the input of frequency-variable module 5 by main switch module 4.Simultaneously, be provided with external path between the input of the output of rectification module 2 and frequency-variable module 5, be connected with auxiliary switch module 6 between this external path.And, between main switch module 4 and auxiliary switch module 6, be connected with driver module 7, on driver module 7, be provided with a communication port 8 at least.
In conjunction with the utility model one preferred implementation, be connected with PNP triode and relay on the communication port 8, come thus frequency-variable module 5 power supplys are carried out suitable control.Simultaneously, in order to help the operate as normal of switch module 4, the work influence of prevention high voltage direct current is connected into main switch module 4 at the output of Voltage stabilizing module 3 by low-voltage direct logical 9 tunnel.In order to satisfy the need of work of frequency-variable module 5, described external path is a high voltage direct current path 10 simultaneously.
Actual operating position from this use in washing machine converter plant, removed traditional step-down module, can adopt the high voltage direct current path 10 of relay control DC level frequency-variable module 5, the logical circuit power VDD of frequency-variable module 5 is then controlled by a PNP triode, only needs an I/O mouth to get final product.And in this course of work, frequency-variable module 5 can all not be in electriferous state all the time, makes the frequency-variable module 5 and the secure context of whole device all be improved.Simultaneously, the logical circuit under step-down module and the frequency-variable module 5 does not have energy consumption when frequency-variable module 5 is not worked, reduced the energy consumption operating position of whole device then, has saved unnecessary waste.
By above-mentioned character express also in conjunction with the accompanying drawings as can be seen, behind employing the utility model, frequency-variable module can all not be in electriferous state all the time.Logical circuit under step-down module and frequency-variable module during the frequency-variable module inoperative does not all have energy consumption simultaneously.Thus, be not only the energy resource consumption of having saved this device, more improved the overall work fail safe of device.
Certainly, more than only be concrete exemplary applications of the present utility model, protection range of the present utility model is not constituted any limitation.In addition to the implementation, the utility model can also have other execution mode.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop within the utility model scope required for protection.
