Soya-bean milk is a kind of Traditional health care beverage that is loved by the people, and great market is arranged.Therefore, various soy bean milk making machine are arisen at the historic moment.These soy bean milk making machine usually by pulverizing, separating part, hot plate usefulness heating part, drive to pulverize the power section that separating part uses and prevent that the liquid level control section that soya-bean milk overflows from forming, shown in 86204692 patent applications (full-automatic domestic soya-bean milk making machine).This patent application improves existing power, heating and anti-overflow (liquid level control) circuit, attempts to make the processing of soya-bean milk to realize automation.But this soy bean milk making machine must be hotted plate soya-bean milk behind cover lid, its process of hotting plate can't be observed, forgotten to add water or water behind the power supply and hot plate time one long hair life very little and burn accidents such as soya-bean milk easily like this, so the security of its use still needs further raising because of carelessness produces to connect.In addition, the anti-overflow part and the part electric elements of this soy bean milk making machine are installed on the lid, such structure, the steam that produces when not only hotting plate soya-bean milk easily enters lid and damages circuit, and lid too heavily makes the center of gravity of soy bean milk making machine improve, when the electric motor starting of power section was pulverized separation, its vibration easily made soy bean milk making machine topple over, and influences its stability; And finish using when cylindrical shell cleaned the also fragile anti-overflow probe of inconvenience not only the user.Because above-mentioned defective, this soy bean milk making machine is difficult to be promoted the use of.

Purpose of the present invention will overcome above-mentioned defective exactly, improves safety in utilization, the reliability of soy bean milk making machine, also makes things convenient for the user.

Purpose of the present invention adopts following scheme to realize.A kind of soya-Bean milk processer, comprise cylindrical shell, pulverize separator, heater, have the fluid level control device of limit sensors 2, it is characterised in that, described soya-Bean milk processer also comprises a minimum liquid level control device that guarantees safe usefulness, and this control device also comprises a sensor 1 that is installed on the above-mentioned lower cylinder wall E; The bottom of described cylindrical shell is provided with a sensing chip B; The control circuit of described fluid level control device and described minimum liquid level control device by instruction circuit 3, instruction circuit 4,

sensor

1 and 2 and sensing chip B form, the circuit controls that sensor 1 forms by sensing chip B and instruction circuit 4 is the relay J of normally closed shape ₁, sensor 2 is the relay J of often opening shape by the circuit controls that sensing chip B and instruction circuit 3 forms ₂; Described heater passes through relay J ₁And J ₂Connect power supply.

Because relay J is in normally off, this soya-Bean milk processer had both made connection power supply heater also can not work when not injecting water.When the E portion of injecting water and water level arrival cylindrical shell in the cylindrical shell contacted with sensor 1, sensor 1 produced a forward current by the conduction and the sensing chip B conducting of water to instruction circuit 4, and instruction circuit 4 sends working signal and makes relay J ₁Action conducting heater makes heater work; The heat that heater produces makes the liquid medium boiling in the cylindrical shell; When the foam that boiling produces arrived the position of sensor 2, sensor 2 produced a forward current by the conduction and the sensing chip B conducting of foam and liquid medium to instruction circuit 3, and instruction circuit 3 sends working signal and makes relay J ₂The electric current of heater is cut off in action; Heater stops heating, and foam reduces, and sensor 2 disconnects with the conduction path of sensing chip B, and to the forward current disappearance of instruction circuit 3, instruction circuit 3 is given relay J ₂Working signal disappear relay J ₂The conducting heater that resets makes heater work.Relay J ₂Electric current by conducting repeatedly like this and disconnection heater is controlled heater work, hots plate until soya-bean milk.And work as the too many of liquid medium evaporation, and when liquid level was lower than E portion, sensor 1 was cut off with the conduction path of sensing unit B, and the forward current that transfers to instruction circuit 4 disappears, and instruction circuit 4 is to relay J ₁Working signal also disappear relay J ₁Reset and cut off the electric current of heater, heater stop work.Though thereby avoid connecting power supply but forgotten in cylindrical shell water filling or the liquid medium evaporation makes liquid level low excessively too much, and soya-Bean milk processer is burnt out or the phenomenon of burning soya-bean milk takes place.This soya-Bean milk processer is arranged on the barrel of cylindrical shell owing to the sensor 2 that the following and anti-overflow that all electric elements is installed in cylindrical shell is used again, and the cap structure of soya-Bean milk processer is lightly rationally not fragile, and makes things convenient for the user to clean cylindrical shell.

Describe embodiment of the present utility model in detail below in conjunction with accompanying drawing, to further specify principle of the present utility model and advantage.

A kind of soya-Bean milk processer of the present utility model as shown in Figure 1, the 6th, pulverize separator, the 7th, cylindrical shell.Sensor 1 is arranged in the minimum liquid level control position E portion of cylindrical shell 7 barrels, and sensor 2 is arranged on the highest liquid level control position of barrel of cylindrical shell 7, and sensing chip B is arranged on the bottom of cylindrical shell 7, all electric elements all be arranged on cylindrical shell 7 below.The frame for movement of the utility model soya-Bean milk processer and principle.Here do not add and launch to state.

Fig. 2 has represented the liquid level control principle of the utility model soya-Bean milk processer.Wherein, when sensor 1 and sensing chip B conducting, sensor 1 sends working signal to instruction circuit 4 and makes relay J ₁Action makes heater 10 work; When sensor 2 and sensing chip B conducting, sensor 2 sends work order to instruction circuit 3 and makes relay J ₂Action makes heater stop work.

A kind of liquid level control circuit of this soya-Bean milk processer as shown in Figure 3.220 volts of power supplys after transformer B step-down, by diode D again through capacitor C ₁Effect become DC voltage, D is ordered draws termination sensing chip B.When D point (sensing chip B) is not connected with sensor 1 or sensor 2, triode G ₁And G ₂All be in cut-off state, relay J ₁Be normally closed shape and J ₂For often opening shape.When injecting water in the cylindrical shell 7 and arriving E portion, D point and sensor 1 are connected under the conduction of water, form D → sensor 1 → resistance R ₁→ G ₁→ F → M → D ₁The loop of → D constitutes instruction circuit 4 makes G ₁Trigger one of formation and make relay J ₁D → the J of action ₁→ G ₁→ F → M → D ₁The loop of → D, at this moment relay J ₁ Action conducting heater 10 makes heater work.At the same time, power set drive to be pulverized separator, the soya bean in this device is pulverized and with cylindrical shell 7 in the water Gehu with become soya-bean milk.The heat that heater 10 sends makes the soya-bean milk boiling, and when the soya-bean milk foam of boiling reached the position of sensor 2, because the conduction of soya-bean milk and soya-bean milk foam, D point and sensor 2 conductings formed D → sensor 2 → R ₂→ G ₂→ F → M → D ₁The loop of → D constitutes instruction circuit 3, under the effect of this circuit, and G ₂Be triggered and form a C → J ₂→ G ₂The loop of → F → M → D → C makes relay J ₂Action, the electric current that cuts off heater 10 makes it stop heating; And descend when heater 10 and soya-bean milk temperature, the soya-bean milk foam drops to sensor 2 height when following thereupon, and the path disconnection of D point (sensing chip B) and sensor 2 makes G ₂The loop of triggering is disconnected G ₂Get back to cut-off state, relay road J ₂Because of action current be cut off reset and again the electric current of conducting heater 10 make it add height that hot soya-bean milk rises to sensor 2 until the soya-bean milk foam path of conducting D point and sensor 2 once again once more.Because the lifting of soya-bean milk foam is made heating process controlled by conducting/cut-out repeatedly, has prevented overflowing of soya-bean milk.And when the water that adds in the cylindrical shell 7 very little or soya-bean milk hot plate the overlong time water evaporates when making the liquid level of soya-bean milk be lower than E portion, it is logical that the not conducting of path of D point and sensor 1 or quilt are cut, G gets back to cut-off state.Relay J ₁Reset to normally closed shape because of operating current is cut off, the electric current of heater 10 is disconnected, and does not carry out work.

The relay J of present embodiment ₁And J ₂What select for use is the Agcdo contact relay, and it has big, the highly sensitive advantage of electric current throughput.The cylindrical shell 7 of present embodiment can be made from a variety of materials, but preferably adopts polycarbonate, and this kind of evidence material can effectively prevent the fouling of soya-bean milk.
