Description

Have the family expenses that stop stir vane assembly automatically and make ice cream equipment

The present invention relates to family expenses and make ice-cream equipment, it comprises an ice cream container, one by electrical motor driven and the ice cream stirring vane that turns round in above-mentioned ice cream container, also comprises an efficient apparatus that stops above-mentioned stirring vane machine operation automatically.

In the ice-cream machine of many manufacturings, the machine operation of stirring vane must stop when ice cream is carried out immediately, just as known, when having reached finite concentration, ice cream is considered to carry out, this concentration is different according to ice-cream kind and each consumer's taste, can be different.

If machine stops operating prematurely, the ice cream concentration rare (uncompleted ice cream) that seems then, thereby poor quality.If on the contrary, machine stops too late, though ice-cream quality remains unaffected, mechanical component, especially sliding-vane motor are vulnerable to unnecessary and harmful stress, and have wasted valuable electric power.Obviously, in fact latter event all may not run into when ice cream is carried out and prepared to restart machine at every turn.

In managing to address this problem, some devices have now been proposed and have used.

For example, provide one of device of use, have tilting work ice cream stirring vane partly, above-mentioned work partly is the banking motion by spring mechanism control.

When stirring vane was run on the predetermined mechanical impedance, its work partly tilted to the position that can not work again, usually beyond the surface of ice cream bodies.Like this some devices reduced the unnecessary stressed and energy waste (though continuously running of motor, but under the condition that reduces load, thereby reduce the ratio of electrical source consumption.Yet), they have some shortcomings clearly, and the most outstanding a bit is the spring mechanism that needs to demarcate the control banking motion, and in well-known prior art, above-mentioned demarcation is a very harsh and very operation of difficulty of requirement; Usually have only factory to install and use, do not allow the user to operate, can differentiate, the ice cream concentration that is considered to relatively adapt under which kind of situation is owing to adopting this mechanism to be restricted.In addition when the concentration of ice cream bulk causes that the work of ice cream paddle is partly outward-dipping, the extraneous factor of following (as parts aging) changes with may being difficult to control.Other included device is some timers, relies on given operating time of these timers to pre-determine, and at the end of this one-period, stirring vane and motor are thrown off and stopped no longer to remain in operation.

Select the operating time should be according to former experience (user and producer long-term that directly obtain or list in the form in the book of ad hoc approach), the operation cycle (time) needs a rough approximation.Because it can not consider these accidental at random phenomenons of temperature, humidity, granulometry and hardness of water.In addition, according to the suggestion of some new methods of attempting, test value requires to push away new.So just introduced the very significantly unreliable factor relevant with the type of attended operation.Thereby arrangement during this period of time is not that too weak point is exactly oversize frequently, however the problem (mechanical stress energy resource consumption) that proposes can reduce widely, but can not eliminate.

Therefore, still unsolved problem provides one and makes the ice cream device, and it comprises one when ice cream is carried out, and for example, reaches the user and wants the concentration of eating can insert arresting stop effectively at the correct time point.

Purpose of the present invention addresses this problem exactly, and make ice-cream device by the user and reach this target, this device comprises an ice cream container, one by electrical motor driven, and the ice cream stirring vane that in above-mentioned ice cream container, rotates, it is characterized in that said apparatus comprises that stops the mechanically operated device of stirring vane automatically, also comprise by measurement inputing to the device of current detecting ice cream concentration of electro-motor and one when input current reaches a predetermined value, cut off and the link device of switch element of circuit of said motor.

According to the present invention, this apparatus features and advantage will be found out from the explanation of following optimum implementation and with reference to the accompanying drawings.Among the figure:

Fig. 1 is the phantom perspective view that device generally is shown according to the present invention.

Fig. 2 is with thinking that Fig. 1 device provides the block diagram of power circuit.

In these figure, sequence number 1 general expression user is used to make ice-cream device.It comprises a box type body 2, is supporting a cylindrical ice cream container 3 in this box type body, and ice cream stirring vane 4 moves therein, and this stirring vane is contained in electrical motor driven in the box type body 2 by it.

This device 1 also comprises a cooling system in order to cooled containers 2, and this cooling system comprises evaporimeter 6, the one condensers 7 cooling electric fan 8 relevant with around container 3, and compressor 9.

This device also comprises power-supply circuit, shown in sketch, 5, the second power lines of first power line, 10 supply motors 11 of this circuit are supplied with electric fan 8 and compressor 9,

power line

10 and 11 end are common pins 12, and they are contained on the box type body 2 to each have

common switch

13,14.

Electric wire 10 also links with a switch element by the control of electronics path, and this path can detect automatically and be input to motor 5 magnitudes of current.

More precisely, as the block diagram among Fig. 2 was described, this electric pathway comprised an adjuster 16, and whole electric currents of supply motor (5) all will flow through it, and produced a scaling signal that is suitable for adjuster 16 and adjuster 17 positions.

From the signal of adjuster 16 output, through an integrator 18 controls one value switch 19 these threshold switches 19 ability output signal when input signal reaches certain pre-value level just.

The signal of threshold switch 19 outputs, storage in memory 20, after this it will act on logic switch 21.By means of voltage drop 23, this switch is arranged to act on the low-voltage line 22 from power line 10, line 22 provides the terminal 24 of the triac (TRIAC) 25 that a Current Control comprises electric wire 10 by switch 21, and TRIAC25 constitutes above-mentioned switch element.People know that TRIAC25 is an electronic component, and its effect is just as gauge tap, and it is not just closed when having power supply to supply with its control terminal 24, and switch is just opened when its terminal 24 is alived.Low-voltage line 22 also provides the power supply of all electronic installations shown in the figure, and these traditional forms are not illustrated.

This device also has an electronics buzzer 26, and it is by controlling from the signal of memory 20 outputs.

The operating principle of this device is illustrated with reference to figure 1 and Fig. 2.

The preparation ice cream, the compressor 9 and electric fan 8 power supplies of at first giving condenser 7 by switch 14 power supply supply lines 11 make container 3 coolings.In case container 3 obtains cooling, will prepare burden and pour in the container 3, and start stirring vane 4 for motor 5 power supplies by switch 13 by electric wire 10 to begin stirring.In this step of operation, TRIAC25 is in closure state, supplies electric current to motor 5.

Along with stirring and the carrying out continuously of cooling, icecream mix will form that a solid composition band more than more and more more and more big mechanical resistance and stirring vane 4 rotates in opposite directions.Along with the increase of the moment of resistance, by obtain more electric current electro-motor 5 work from electric wire 10.

Thereby the signal of exporting from adjuster 16 becomes stronger simultaneously; Certain a bit on, above-mentioned signal (preventing by at interval and the current peak that produces at random the faulty operation that causes as suitably being connected by integrator 18) will reach the level of enough starting value switches 19.The signal level of the value of being input to switch 19 will depend on the place value of ice-cream concentration and adjuster 17, promptly all have a different ice cream concentration value corresponding with it with respect to each position of speed regulator 17, and at these concentration value points, value switch 19 is in enable position.

19 startups of value switch cause signal to be provided to memory 20, and signal will be delivered to logic switch 21 after being stored to memory 20, thereby connect low-voltage line 22.Like this, electrode 24 gives voltage starting TRIAC25, and motor 5 disconnects, and stirring vane is stopped.Line 10 disconnects, the value that terminated switch 19 outside output signals, but the logic switch 21 that has is closed by the signal that before was stored in the memory 20.

With the unlatching synchronised of control TRIAC25, memory 20 has also triggered electronics buzzer 26, and this buzzer is reported to the police to the user, and ice cream is carried out.Because the freezing work that must be so the continuous line 11 that links with refrigeration system provides is nonautomatic.

The work of cutting off buzzer 26 will be enough to move switch 13 to the position of opening an account.The opening an account of switch 13 also caused comprising the removing of the device signal of the signal that is stored in the memory, and then Closing Switch 13 former duties automatically are restored.

Use device of the present invention.The user can come for every retaining selection of time one preferable ice-cream concentration.

At last, the present invention will be enough to satisfy users' control operation adjuster; For the present invention is simplified, adjuster 17 can provide a graduated scale (not showing among the figure) expediently.

When ice cream reaches desired concentration, the stirring work of stirring vane will automatically stop.

Therefore, chatting the problem (when ice cream was carried out, this device automatically stopped) that is partly described in detail before this specification has almost all solved.One perfect ice cream is in the energy consumption of minimum and do not have to have obtained under the excessive mechanical stress.
