In this way, the operation principle of switch portion 112 is realized, meanwhile, the structure of above-mentioned switch portion 112 is also relatively simple.
Specifically, conducting strip 160 can be fixed on the lateral surfaces of water box 110 and is connected with facilitating with conductive part.Conducting strip 160 connects
The first conductive part 162 and the second conductive part 164 are connect, turns on switch portion 112；Conducting strip 160 with the first conductive part 162,
Two conductive parts 164, the 3rd conductive part 166 and the 4th conductive part 168 disconnect, and disconnect switch portion 112；Conducting strip 160 connects
The 3rd conductive part 166 and the 4th conductive part 168 are connect, turns on switch portion 112.
Conducting strip 160, the first conductive part 162, the second conductive part 164, the 3rd conductive part 166 and the 4th conductive part 168 are equal
It can be made of metal material.First conductive part 162, the second conductive part 164, the 3rd conductive part 166 and the 4th conductive part 168 are equal
It can be fabricated to easy to process cylindric.In the present example, Figure 17 and Figure 24 please be join, the first conductive part 162 and second are led
Electric portion 164 can be connected to a water level detecting loop of circuit board 122 by wire 306,308 respectively；3rd conductive part 166 and
4th conductive part 168 can be connected to another water level detecting loop of circuit board 122 by wire 310,312 respectively.
When switch portion 112 turns on, controller 108 is by judging to be which water level detecting loop conducting to judge water box
110 water level is the first water level or the 3rd water level.
In embodiments of the present invention, drive division 114 can also use driving of the elastic force of elastic component as drive division 114
Power.Illustrated below so that elastic component is spring as an example and with reference to Figure 22, Figure 23 and Figure 24.
When initial, when the water level of water box 110 is three water level, the water of water box 110 causes the gravity of water box 110 when more
More than the elastic force of spring, spring is compressed, and water box 110 connect the 3rd conductive part 166 and the 4th in the 3rd position, conducting strip 160
Conductive part 168, conducting strip 160 disconnect with the first conductive part 162 and the second conductive part 164, at this moment by wire 310, conduction
The first water level detecting loop that piece 160, the 3rd conductive part 166, the 4th conductive part 168, wire 312 are formed is in the conduction state,
The second water level detecting loop being made up of wire 306, conducting strip 160, the first conductive part 162, the second conductive part 164, wire 308
It is off.First water level detecting loop in the conduction state sends control signal, controller 108 to controller 108
Control signal is received, judges the water level of water box 110 for the 3rd water level, water filling device 148 is closed.
When user uses the cooking function of steam microwave oven 100, the water level in water box 110 slowly declines, water box 110
Water, which is reduced, causes the gravity of water box 110 to gradually decrease, and the compression of spring gradually recovers, and the elastic force of spring is more than the weight of water box 110
Power, both driving water box 110 of making a concerted effort move to the second place and first position.During the water level decreasing of water box 110, water
Box 110 in the second place, conducting strip 160 with the first conductive part 162, the second conductive part 164, the 3rd conductive part 166 and the 4th
Conductive part 168 disconnects, and switch portion 112, which disconnects, causes the first water level detecting loop and the second water level detecting loop to disconnect,
Controller 108 judges the water level of water box 110 for the second water level.
When the water level of water box 110 further drops to the first water level, spring returns to setting value, and water box 110 are first
Position, conducting strip 160 connect the first conductive part 162 and the second conductive part 164, the conductive part 166 and the 4th of conducting strip 160 and the 3rd
Conductive part 168 disconnects, at this moment by wire 310, conducting strip 160, the 3rd conductive part 166, the 4th conductive part 168, wire 312
The the first water level detecting loop formed is off, conductive by wire 306, conducting strip 160, the first conductive part 162, second
The second water level detecting loop that portion 164, wire 308 are formed is in the conduction state and sends control signal to controller 108.Control
After device 108 receives control signal, the water level of water box 110 is judged for the first water level, and control water filling device 148 is opened, external water source
By water inlet pipe 158 (i.e. the second water pipe) to the water filling of water box 110.
At this moment, the water level of water box 110 slowly raises, and 110 increased water of water box causes the gravity of water box 110 gradually to increase,
Spring is gradually compressed, and the elastic force of spring is less than the gravity of water box 110, both driving water box 110 of making a concerted effort to the second place and
Move 3rd position.When the water level of water box 110 rises to three water levels, spring is compressed to setting value, and water box 110 are at the 3rd
Put, conducting strip 160 connects the 3rd conductive part 166 and the 4th conductive part 168, conducting strip 160 are led with the first conductive part 162 and second
Electric portion 164 disconnects, at this moment by wire 3310, conducting strip 160, the 3rd conductive part 166, the 4th conductive part 168, wire 312
The the first water level detecting loop formed is in the conduction state, conductive by wire 306, conducting strip 160, the first conductive part 162, second
The second water level detecting loop that portion 164, wire 308 are formed is off.First water level detecting in the conduction state is returned
Road direction controller 108 sends control signal, and controller 108 receives control signal, judges the water level of water box 110 for the 3rd water
Position, control water filling device 148 are closed to stop to the water filling of water box 110.
