The overflow-prevention automatic milk boiling pot has the advantages that the fresh milk can be prevented from overflowing to cause the waste and from overflowing to extinguish the fire or to cause the short circuit of the power source.

Description

Overflow-prevention automatic milk boiling pot

Affiliated technical field:

The present invention is a kind of milk boiler, especially a kind of overflow-prevention automatic milk boiling pot.

Background technology:

Present employed various milk boilers, generally with open firing or electrical heating, its weak point is: rear excessive pot easily of fresh milk boiling, waste fresh milk is also put easily naked light out by water or is made short circuit, cause danger.

Summary of the invention:

The utility model has overcome deficiency of the prior art, automatically cuts off thermal source after the fresh milk boiling, and starts immediately the air blast cooling cooling, prevents that Yu Wen from making fresh milk continue boiling.

The technical scheme that the utility model adopts is: milk boiler is by the pot body, electric heater unit and electric control circuit form, and are provided with the pot contact of overflowing at the pot wall, this contact and the insulation of pot wall, after the fresh milk boiling, pot wall is communicated with the contact, and triggers electric control circuit by probe.

The utility model can also be provided with temperature sensing device, cuts off the heater power supply immediately after fresh milk reaches the requirement temperature detecting.Can also be provided with the calandria release unit, calandria is separated with the milk pot; And can be provided with the forced cooling device, and after the fresh milk boiling, immediately the milk pot is implemented forced cooling, prevent that Yu Wen from making fresh milk continue boiling.The forced cooling device of this milk pot can be designed to control temperature fall time with timing mode; Also can be designed to definite value cooling circuit, after the fresh milk temperature is reduced to designated value, quit work automatically.The utility model can also be provided with gravity switch, when liquid in the milk pot pot behind the less or milk pot disengaging calandria, and whole device auto-breaking.

The beneficial effects of the utility model are: prevent that the fresh milk pot that overflows from causing waste, prevent from that fresh milk from overflowing to put naked light out by water or make power supply short circuit cause danger.

The specific embodiment

Embodiment 1: as Fig. 1 and Fig. 2, after adding fresh milk, milk pot 1 is placed on the heater 2, thereby connect power supply by gravity switch under the gravity pressure 3, intensification control knob 11 is set at the gear that boils, set cooling 12 control times of (timing) button as required, heater circuit work begins heating, when heating fresh milk boils boiling, fresh milk after the boiling touches the pot contact 15 of overflowing, pot wall is communicated with the contact, after the pot probe 14 that overflow detects, by receiver amplifier signal is delivered to the intensification control circuit, the intensification control circuit cuts off the heater circuit power supply and stops heating, send a signal to the cooling time control circuit simultaneously, the cooling time control circuit sends instruction, electromagnet 7 adhesive armatures 6, pallet 4 rotates around axle 5, and heater 2 moves downward the bottom of a pan that breaks away from milk pot 1, and cooling fan 8 starts forced cooling simultaneously, alarming horn 10 music of sounding, after Preset Time arrived, cooling fan was out of service, and the warning music stops simultaneously, fresh milk can be drunk, when milk pot when heater is picked up, gravity switch 3 resets, the entire circuit outage.Less than 100 ℃, the intensification temperature arrives when setting value, and after being detected by temp probe 13, by receiver amplifier signal is delivered to the intensification control circuit such as wish heating fresh milk Temperature Setting, and the intensification control circuit cuts off heater circuit power supply stopped heating and gets final product.At this moment, anti-overflow pot probe can also play temperature sensing circuit malfunctioning after, the overflow monitoring and protecting of pot of fresh milk.The operating valve value of gravity switch 3 is greater than empty pot and adds the weight summation of 20 to 50 grams (size on pot is decided) fresh milk, so both can play pot from the disconnected effect of electricity, also can play the effect that prevents the empty pot of dry combustion method.Overflow pot contact 15 will and the pot body between insulate.Counterweight armature 6 plays the double action of armature and counterweight simultaneously, and heater 2 is close to the bottom of a pan of milk pot 1 under the assurance heated condition.

Overflow-prevention automatic milk boiling pot timing cooling type schematic block circuit diagram such as Fig. 2, k1 is the pot sensor-based system that overflows among the figure, i.e. 14 among Fig. 1 and 15 combination; K2 is that gravity switch is 3 among Fig. 1; T is that temp probe is 13 among Fig. 1.Temperature display circuit provides visual data for observing and understanding heating state.

Embodiment 2: as Fig. 1 and Fig. 3, after adding fresh milk, milk pot 1 is placed on the heater 2, thereby connect power supply by gravity switch under the gravity pressure 3, intensification control knob 11 is set at the gear that boils, and set the temperature value of cooling back fresh milks with cooling button 12, heater circuit work begins heating, when heating fresh milk boils boiling, fresh milk after the boiling touches the pot contact 15 of overflowing, pot wall is communicated with the contact, after the pot probe 14 that overflow detects, by receiver amplifier signal is delivered to the intensification control circuit, the intensification control circuit cuts off the heater circuit power supply and stops heating, send a signal to the cooling control circuit simultaneously, the cooling circuit is started working, at this moment, the cooling control circuit sends the instruction of first road, electromagnet 7 adhesive armatures 6, pallet 4 rotates around axle 5, heater 2 moves downward the bottom of a pan that breaks away from milk pot 1, and cooling fan 8 starts forced coolings simultaneously, alarming horn 10 music of sounding, when fresh milk reaches default cooling value, temperature popped one's head in 13 detect after, deliver to the cooling control circuit by receiving amplifying circuit, the cooling control circuit sends the instruction of second road, cooling fan is out of service, the warning music stops simultaneously, and fresh milk can be drunk, when milk pot when heater is picked up, gravity switch 3 resets, the entire circuit outage.Less than 100 ℃, the intensification temperature arrives when setting value, and after being detected by temp probe 13, by receiver amplifier signal is delivered to the intensification control circuit such as wish heating fresh milk Temperature Setting, and the intensification control circuit cuts off heater circuit power supply stopped heating and gets final product.At this moment, anti-overflow pot probe can also play temperature sensing circuit malfunctioning after, the overflow monitoring and protecting of pot of fresh milk.The operating valve value of gravity switch 3 is greater than empty pot and adds the weight summation of 20 to 50 grams (size on pot is decided) fresh milk, so both can play pot from the disconnected effect of electricity, also can play the effect that prevents the empty pot of dry combustion method.Overflow pot contact 15 will and the pot body between insulate.Counterweight armature 6 plays the double action of armature and counterweight simultaneously, and heater 2 is close to the bottom of a pan of milk pot 1 under the assurance heated condition.
