The break-make detector of the refrigerating circuit of the present embodiment, including pipe fitting, float 5 and close switch 6.Wherein, pipe fitting connects
Enter in refrigerating circuit；Float 5 is located in pipe fitting, and is moved along pipe fitting under the effect of pipe fitting inner refrigerant；It is used for close to switch 6
The position of the float 5 is detected, and sends out detection signal when float 5 moves to induction region.Wherein, detection signal is refrigeration
The Continuity signal in circuit.
The break-make detector of the refrigerating circuit of the present embodiment, accesses in refrigerating circuit.When refrigerating circuit works normally
When, pipe fitting inner refrigerant flows and float 5 is driven to be moved towards close to switch 6, until float 5 moves to the sense close to switch 6
Region is answered, detection signal is sent out close to switch 6 at this time, illustrates refrigerating circuit normally at this time, is had in refrigerating circuit enough
Refrigerant circulation.Conversely, if float 5 can not move to the induction region close to switch 6, illustrate that refrigerating circuit is not normal
Conducting.The break-make detector of the refrigerating circuit of the present embodiment can detect the failure of refrigerating circuit in time, prompt user, make
The article taken in conjunction maintenance personnel stored in user's energy timely processing refrigerator.
Wherein, the abnormal conducting of refrigerating circuit, in fact it could happen that the problem of be that compressor can not work normally, it is also possible to make
The non-normally of switch valve in cold loop.For example, when being connected by solenoid directional control valve 1 between compressor and evaporator, at this time
It is likely to the failure of solenoid directional control valve 1.
In the present embodiment, the type of float 5 and close switch 6 is unlimited, as long as float 5 can be with refrigerant stream in pipe fitting
Lead to and move in the tube, and the change in location of place's float 5 can be detected close to switch 6.
For example, in the present embodiment, float 5 and close switch 6 can select magnetic float 5 and Hall switch respectively, to
When magnetic float 5 moves to the induction region of Hall switch, Hall switch starts and sends out detection signal.
For another example in the present embodiment, float 5 and close switch 6 can select photoelectricity float 5 and optoelectronic switch respectively.Again
For example, float 5 and close switch 6 can also select common float 5 and infrared induction switch ... respectively
Refer to Fig. 2 and Fig. 3, in the present embodiment, pipe fitting includes the first pipeline section 7 for accommodating float 5, float 5 just
Beginning position is located at the input end of first pipeline section 7, is arranged close to switch 6 in the outlet end of the first pipeline section 7.The break-make is detected
Device accesses in refrigerating circuit, to which when refrigerant circulation reaches setting value in refrigerating circuit, float 5 is acted in refrigerant
Under moved towards close to switch 6, and move in the induction zone for approaching switch 6.
In the present embodiment, pipe fitting is preferably necessarily still copper pipe.
Wherein, the first distribution vertically of pipeline section 7, and then when refrigerant circulation does not reach setting value, float 5 is in weight
Its initial position is returned under force effect.Certainly, the distribution of the first pipeline section 7 is not limited by illustrating herein.For example, the first pipeline section 7
Can also horizontal distribution, at this time float 5 can be resetted by other forms.For example, float 5 can be connected to a reset bullet
Spring.
In Fig. 2 and Fig. 3, the bottom end of the first pipeline section 7 is input end, and top is outlet end, and the cross section of input end is less than
The cross section of outlet end.To which when refrigerant flows through the first pipeline section 7, float 5 is from input end towards when outlet end motion, and float 5 is not
Outlet end can be blocked.
Wherein, preferably but necessarily pipe fitting further includes second pipeline section 8 at an angle to each other with first pipeline section 7, and first
Pipeline section 7 and the second pipeline section 8 are set gradually in refrigerating circuit, and are formed with contraction between the first pipeline section 7 and second pipeline section 8
Mouthful.In the case of this kind, it can prevent float 5 from entering the second pipeline section 8.
Wherein, preferably but necessarily the first pipeline section 7 is parallel with second pipeline section 8, to include 7 He of the first pipeline section
The pipe fitting of second pipeline section 8, distance is small between inlet and outlet, conveniently accesses in refrigerating circuit.
In addition, the break-make detector of the present embodiment, further includes protection pipe, it is arranged in the outer end of pipe fitting, and then can be to pipe
Part plays a protective role.
The present embodiment also provides a kind of refrigeration system, including the system that compressor, condenser, evaporator and throttling set are formed
Cold loop is equipped with above-mentioned break-make detector in the refrigerating circuit.
Wherein, which can be applied on refrigerator, air-conditioning or heat pump product.
In addition, the present embodiment also provides a kind of refrigerator, including above-mentioned refrigeration system.
Wherein, the quantity of the evaporator of refrigerator is multiple, and is connected in parallel in the refrigerating circuit；Each evaporator is gone here and there respectively
There are one the break-make detectors for connection.For example, evaporator common in refrigerator includes freezer evaporator and refrigerator evaporator.
Certainly, in addition to this, when refrigerator includes temperature-changing chamber, then evaporator further includes temperature-changing chamber evaporator.
Wherein, it is connected by solenoid directional control valve 1 between multiple evaporators and the compressor.
For example, when refrigerator includes three evaporators, then solenoid directional control valve 1 includes three outlets, respectively exports B2, goes out
Mouthful C3, outlet D4, and export B2, outlet C3, outlet D4 respectively with three evaporator series.Also, belonging to three evaporators
The above break-make detector is in series on circuit respectively, it is assumed that break-make detector is break-make detector B, break-make detector C, break-make are examined
Survey device D.
When the compressor is shut down, at this point, break-make detector B, break-make detector C, break-make detector D are disconnected.Work as compression
When machine is switched on, if solenoid directional control valve 1 leads to outlet B2, break-make detector B is closed；If solenoid directional control valve 1 leads to outlet
C3, then break-make detector C be closed；If solenoid directional control valve 1 leads to outlet D4, break-make detector D is closed.When compressor is opened
Machine, and solenoid directional control valve 1 is connected, if corresponding break-make detector is unable to normally closed, illustrates that current refrigeration circuit occurs
Failure prompts user, enables users to the article taken in conjunction maintenance personnel stored in timely processing refrigerator.
Certainly, when evaporator quantity is multiple, other switch valves can also be passed through between evaporator and compressor
Connection.Also, the evaporator quantity of refrigerator is not also limited by illustrating herein.
Further, case further includes controller, and controller connects break-make detector and solenoid directional control valve 1, works as electromagnetic switch
One of valve 1 outlet conducting, and send out detection signal with the concatenated break-make detector in the outlet of conducting, then controller judges
Refrigerator works normally；Otherwise, controller control refrigerator sends out alarm signal.Also, controller can specifically be judged between which
Room refrigeration is abnormal.For example, when the evaporator connect compressor of refrigerating chamber, if the corresponding break-make detector of refrigerating chamber is not
Continuity signal is sent out, then illustrates refrigeration chamber exception, user's timely processing can be notified to refrigerate indoor food at this time, avoided
The damage of consumer articles.
Also, the refrigerator of the present embodiment is easier to find the exception of solenoid directional control valve 1, Jin Erfang in process of production
The product that stop-band problem comes into the market.
The present embodiment also provides a kind of method carrying out refrigeration detection using the above break-make detector, including：
