Steam-generating equipment of washing machine of the present invention 181 supplies water to shell 182 internal cavities from the feed water inlet, and heater 184 generates steam with the water heating, and the steam of generation is transported in the cylinder 30 by steam drain 183.
Described level sensor (not shown) is surveyed the moisture storage capacity in shell 182 internal cavities, works under the low excessively state of the water level of heater 184 in shell 182 internal cavities preventing.
When causing heater 184 overheated because of chance failure or faulty operation, described the 1st over-temperature protection 186 can cut off the power supply of heater 184 immediately, and is further overheated to prevent heater 184.
But, as shown in Figure 6, if because of washing machine correctly is not installed on the level ground, perhaps because of assembling the improper steam raising plant 180 that causes not when level tilts, described the 1st over-temperature protection 186 might be able to not cut off the power supply of heater 184, does not have the heater 184 further overheated effects that prevent.
In more detail, when described steam raising plant 80 run-off the straights, the 1st over-temperature protection 186 of heater 184 still is immersed in the water, but when surface in the other end of heater 184, described the 1st over-temperature protection 186 is just surveyed the generation less than superheating phenomenon, can not cut off the power supply of heater 184, cause heater 184 to work on mistakenly.
But, because the just radiation towards periphery of heat that this end produces is surfaced in the other end of described heater 184.
Since described the 2nd over-temperature protection 188 be arranged on just heater 184 do not install the 1st over-temperature protection 186 a side end directly over, so the 2nd over-temperature protection 188 can in time detect the radiant heat of the heater 184 ends generation of surfacing, when the temperature value that detects when the 2nd over-temperature protection 188 is higher than fiducial temperature, just can cut off the power supply of heater 184 immediately, heater 184 is quit work, thereby prevent the generation of superheating phenomenon effectively.
It is worthy of note; protection scope of the present invention is not limited to the above-mentioned specific embodiment, and according to basic fundamental design of the present invention, one of ordinary skill in the art need not through creative work; can associate other multiple specific embodiment, these all belong to protection scope of the present invention.
