Abstract

The utility model relates to a stirrer which can make ice cream in a chilling chamber of a refrigeration facility. The utility model is especially suitable for domestic refrigerators. A spring sleeve with a contact arm is arranged on a motor shaft, the technology of which is known by public. To match the spring sleeve, a limited post and a microswitch are arranged on an upper cover. When the ice cream is made up, the power supply of a motor can be cut off automatically. The microswitch and an alarm device which is out of the refrigeration facility are connected by a conductor wire. The utility model has the advantages of little electricity, easy operation, and low cost. The making situation of the ice cream can be known in time.

Description

Ice cream mixer with alarm and auto-stopping

The utility model relates in a kind of refrigerating chamber that is used in refrigeration plant manufactures ice-cream agitator, is specially adapted in the household electric refrigerator.

Manufacturing ice-cream agitator in the known technology in the refrigerating chamber of refrigeration plant is made up of container, paddle, loam cake, permagnetic synchronous motor, safety guard and electric apparatus control apparatus etc., this agitator is not owing to can cut off the electricity supply automatically after making ice cream, motor continues consumed power, cause motor the temperature rise phenomenon to occur, might make the ice cream of making phenomenon occur melting, people are in order in time to grasp the ice-cream situation of manufacturing, just need constantly open refrigerating chamber and watch, thereby increase the power consumption of refrigeration plant.

The purpose of this utility model is to overcome the known technology weak point, can cut off the electricity supply and send the ice cream stirrer of alarm signal after providing a kind of ice cream to make automatically.

The purpose of this utility model realizes by following proposal.

The elasticity contact arm is housed on the motor shaft in known technology, and corresponding with it is that two limited posts and a microswitch are housed on the loam cake plane; On the operating circuit that the light emitting diode of resistance by parallel connection and microswitch and motor are formed, be connected with warning device.

Elasticity contact arm described in the utility model is to stretch the spring housing that contact arm is arranged by the two ends that steel wire twines by the dextrorotation direction.

D.C. regulated power supply and a music integrated circuit that has ceramic sound equipment sheet that capacitance-resistance rectification circuit that warning device described in the utility model is concatenated into by electric capacity, resistance, two diode connected in parallel and filter regulator circuit are formed are formed; Two working ends of music integrated circuit and filter regulator circuit parallel connection, its switch terminals and electric capacity, start button, microswitch are connected into on-off circuit.

Filter regulator circuit described in the utility model can be to be composed in parallel by electrochemical capacitor and voltage-stabiliser tube, also can compose in parallel with the light emitting diode that is cascaded and two diodes.

Description of drawings:

Fig. 1: the assembling schematic diagram that is the utility model embodiment.

Fig. 2: the A that is Fig. 1 is to partial schematic diagram.

Fig. 3: the circuit theory diagrams that are the utility model embodiment.

Fig. 4: the equivalent circuit diagram that is voltage-stabiliser tube.

The contrast relationship of figure number and other parts is in the accompanying drawing: 1 for music-integrating block, 15 for voltage-stabiliser tube, 16 for light emitting diode, 17 for spring housing, 18 is spring housing for ceramic buzzing sheet, 14 for the start button, 11 on the warning device, for lead, 12 for warning device, 13 for microswitch, 10 for limited post, 9 for spring housing, 7,8 for safety guard, 6 for paddle, 5 for permagnetic synchronous motor, 4 for loam cake, 3 for container, 2.

In conjunction with the accompanying drawings embodiment of the present utility model is specified in down:

The container 1 of ice cream materials is housed, be stamped loam cake 2 at an upper portion thereof, at the last permagnetic synchronous motor 3 that 220V, 3W are housed that covers, motor shaft is connected with paddle 4 in the container by the loam cake centre bore, motor is covered with the safety guard 6 that is fixed in loam cake, on motor shaft, be equipped with the dextrorotation that twines with steel wire spring housing 6, respectively stretch at the spring housing two ends that contact arm is arranged, what be complementary with spring housing is that two

limited posts

7 and 8 and microswitches 9 are housed on the loam cake plane; By lead 11 motor, microswitch and warning device 12 that start button is housed are connected into a loop, the circuit of warning device be parallel to by and then R ₁Light emitting diode 16, the normally opened contact K of microswitch ₉On the operating circuit that is connected into motor, this circuit is by C ₁, R ₂D with parallel connection ₂, D ₃The capacitance-resistance rectification circuit that is concatenated into mutually and by C ₂, voltage-stabiliser tube 15 and the filter regulator circuit that the is connected into D.C. regulated power supply and a music-integrating block that has ceramic buzzing sheet 13 14 compositions, two working end m of music-integrating block formed ₁, m ₂In parallel with the two ends of voltage-stabiliser tube, its switch terminals m ₃With C ₃, start button normally-closed contact K ₁₀', the normally-closed contact K of microswitch ₉' be connected into on-off circuit.

Agitator is pressed the start button at 10 places on the warning device 12 that is placed on the refrigerator outside, K after connecting the 220V power supply ₁₀Connect, at this moment the K of microswitch ₉' be original connection, motor passes through K ₉', K ₁₀Form path, machine operation; Have only when motor turn to spring housing around when opposite, the contact arm that could drive 17 places of spring housing is depressed microswitch, makes K ₉Connect, the operating circuit of motor just can be normal path, and this moment, skidding appearred in motor shaft in spring housing, and start button just can unclamp, and it is bright that light emitting diode is; Start the back as occur motor steering and spring housing around when consistent, the contact arm at spring housing 17 places rotates limited post 7 with axle and blocks, the contact arm at spring housing 18 places is rotated further with motor shaft, cause spring to be locked to be around in motor shaft and produce a resistive torque, make motor generation counter-rotating, this just can reach motor shaft turn to spring housing around to opposite requirement.After ice cream stirs into make the counter-rotational resistive torque of motor because ice-cream resistance forms one, make turning to of motor become with spring around to consistent, thereby the contact arm at spring housing 17 places leaves microswitch, K ₉Disconnect, operating circuit is and opens circuit, the motor stall, and light emitting diode is secretly, reaches the purpose of cutting off the electricity supply automatically, meanwhile because K ₉' to connect, the on-off circuit of music-integrating block and D.C. regulated power supply are connected and are sent the music sound, inform people with warning.

The utility model has the advantages that because microswitch has been installed, in time cut off electricity The source can be reduced the power consumption of agitator and be shortened the time that ice cream is manufactured; Owing to increased warning device, can save refrigerating chamber because often opening the energy consumption that causes, can understand again the ice-cream situation of manufacturing; Implement easily, cost is low.
