Backup system 3 includes power supply and selects modular converter 31 and accumulator 32.
Power supply selects modular converter 31 to be connected with power supply live wire L and power supply zero line N, and accumulator 32 selects modular converter 31 to be connected with power supply, and power supply selects modular converter 31 to be also connected with master control borad 6.
When dish-washing machine is the dish-washing machine of Alternating Current Power Supply, and power supply 9 is when being alternating current power supply, power supply selects modular converter 31 to judge whether power supply live wire L exists alternating current, if there is alternating current in power supply live wire L, then power supply selects modular converter 31 by this alternating current output to master control borad 6, if power supply live wire L is absent from alternating current, then power supply selects modular converter 31 to export to master control borad 6 after the unidirectional current that accumulator 32 exports is converted to alternating current.
When dish-washing machine is the dish-washing machine of direct current supply, and power supply 9 is when being alternating current power supply, power supply selects modular converter 31 to judge whether power supply live wire L exists alternating current, if there is alternating current in power supply live wire L, then power supply selects modular converter 31 to export to master control borad 6 after this alternating current is converted to unidirectional current, if power supply live wire L is absent from alternating current, then power supply selects modular converter 31 to draw unidirectional current to master control borad 6 from accumulator 32.
When dish-washing machine is the dish-washing machine of Alternating Current Power Supply, and power supply 9 is when being DC source, power supply selects modular converter 31 to judge whether power supply live wire L exists unidirectional current, if there is unidirectional current in power supply live wire L, then power supply selects modular converter 31 to export to 6 master control borads after this unidirectional current is converted to alternating current, if power supply live wire L is absent from unidirectional current, then power supply selects modular converter 31 to export to master control borad 6 after the unidirectional current that accumulator 32 exports is converted to alternating current.
When dish-washing machine is the dish-washing machine of direct current supply, and power supply 9 is when being DC source, power supply selects modular converter 31 to judge whether power supply live wire L exists unidirectional current, if there is unidirectional current in power supply live wire L, then power supply selects modular converter 31 by this unidirectional current output to master control borad 6, if power supply live wire L is absent from unidirectional current, then power supply selects modular converter 31 to draw unidirectional current to master control borad 6 from accumulator 32.Wherein, accumulator 32 can be in actual applications lithium battery, lithium polymer battery, Ni-MH battery or other possess electric energy charge and discharge characteristic for electrolyte.
It should be noted that, in the above-mentioned latter in electric power system 3, in order to guarantee when power supply 9 is stopped power supply, power supply live wire L to be detected, power supply selects modular converter 31 to be actually and obtains power supply from accumulator 32, in order to realize the detection to power supply live wire L when dish-washing machine is opened.
It is charged owing to the accumulator 32 in above-mentioned backup system 3 requires over external power supply when electricity deficiency, if just had a power failure when accumulator 32 electricity deficiency, then can have impact on the normal power supply to dish-washing machine to a certain extent, therefore, in an alternative embodiment of the invention, in order to make accumulator 32 can keep the electricity of abundance, as shown in Figure 3, backup system 3 also includes accumulator charging module 33, accumulator charging module 33 connects power supply live wire L and power supply zero line N, and is connected with accumulator 32.

When live wire of powering is absent from alternating current; power supply selects modular converter 31 can export to master control borad 6 after the unidirectional current that accumulator 32 exports is converted to alternating current, then master control borad 6 selects modular converter 31 obtain alternating current and drive heat-generating pipe 5, washing pump 7 and protect load 8 so that dish-washing machine normal operation when dish-washing machine is opened from power supply.
(2) when dish-washing machine is the dish-washing machine of direct current supply; and power supply 9 is when being alternating current power supply; if there is alternating current in power supply live wire L; power supply selection modular converter 31 can export after this alternating current is converted to unidirectional current powers to master control borad 6; then master control borad 6 directly selects modular converter 31 to obtain unidirectional current from power supply when dish-washing machine is opened, and opens heat-generating pipe 5, washing pump 7 and other protection loads 8 so that dish-washing machine realizes normal operation according to different washing procedures.And there is alternating current at power supply live wire L, but voltage instability timing, owing to power supply selects modular converter 31 to detect there is alternating current in power supply live wire L, so now master control borad 6 still selects modular converter 31 to obtain unidirectional current when dish-washing machine is opened from power supply, if and power supply 9 has a power failure suddenly in dishwasher into operation process, then power supply selection modular converter 31 can detect that power supply live wire L is absent from alternating current, and draw unidirectional current output to master control borad 6 from accumulator 32, then dish-washing machine moment be converted to accumulator 32 power time, because its power-failure memory function works on, thus reaching the purpose quickly realizing power switching to ensure the normal operation of dish-washing machine.
Above-mentioned master control borad 6 selects modular converter 31 to obtain galvanic from power supply while, accumulator charging module 33 can detect and judge that whether the electricity of accumulator 32 is sufficient, it is, then continue cycling through the electricity of detection accumulator 32, no, then accumulator charging module 33 can convert the alternating current of power supply live wire L input to unidirectional current is that accumulator 32 is charged, so that accumulator 32 keeps sufficient electricity.
When live wire of powering is absent from alternating current; power supply selects modular converter 31 can draw unidirectional current from accumulator 32 to export to master control borad 6, then master control borad 6 selects modular converter 31 obtain unidirectional current and drive heat-generating pipe 5, washing pump 7 and protect load 8 so that dish-washing machine normal operation when dish-washing machine is opened from power supply.
(3) when dish-washing machine is the dish-washing machine of Alternating Current Power Supply; and power supply 9 is when being DC source; if there is unidirectional current in power supply live wire L; power supply selection modular converter 31 can export after this unidirectional current is converted to alternating current powers to master control borad 6; then master control borad 6 directly selects modular converter 31 to obtain alternating current from power supply when dish-washing machine is opened, and opens heat-generating pipe 5, washing pump 7 and other protection loads 8 so that dish-washing machine realizes normal operation according to different washing procedures.And there is unidirectional current at power supply live wire L, but voltage instability timing, owing to power supply selects modular converter 31 to detect there is unidirectional current in power supply live wire L, so now master control borad 6 still selects modular converter 31 to obtain alternating current when dish-washing machine is opened from power supply, if and power supply 9 has a power failure suddenly in dishwasher into operation process, then power supply selection modular converter 31 can detect that power supply live wire L is absent from unidirectional current, and export after the unidirectional current that accumulator 32 exports is converted to alternating current to master control borad 6, then dish-washing machine moment be converted to accumulator 32 power time, because its power-failure memory function works on, thus reaching the purpose quickly realizing power switching to ensure the normal operation of dish-washing machine.
