The refrigerating appliance of substance, particularly food, and it is related to a kind of method for drying the substance in refrigerating appliance.
Background technique
Nearly all refrigerating appliance tends to make to be stored in the exsiccation of the cooled material in the refrigerating appliance to a certain extent,
It is lost from cooled material on an evaporator and thus because the moisture evaporated from cooled material tends to cohesion.The effect is in nothing
Be in white refrigerating appliance it is particularly apparent, cooled material and evaporator are spatially separated in the no-frost refrigeration device.Especially
Although being thus unpacked leafy vegetable tends to quick atrophy in frost-free refrigerator, on the other hand the exsiccation is not sufficiently strong
Ground is for realizing targetedly drying food.
In most no-frost refrigeration devices, heating device is set in evaporator room, to defrost to evaporator.Work as evaporation
When device does not cool down simultaneously, and when the ventilation for recycling air between evaporator room and storage cell compartment in normal cooling operation
When machine is also switched off, then the heating device is just run.
A kind of refrigerating appliance as known in JP 2008032392, wherein heating device is arranged in storage cell compartment, so as to
The content of drying storage cell compartment.However the efficiency of the drying is limited.Storage cell compartment is placed in about by heating device
Without open in itself, this view advances an idea, i.e., the described heating device is arranged on the bottom of storage cell compartment.When the cell compartment is complete
Full when being filled, then this causes heat must be by drying object until the surface of the drying object just sheds, the thus heat
It can promote to evaporate there；Heat scatters and disappears to the lower part simultaneously.Placement of the heating device above drying object, which is also not, makes us full
Meaning, because heating device and drying object are then isolated from each other by the cold air being blown into the cell compartment.
Summary of the invention
The task of the present invention is to provide a kind of refrigerating appliance, the refrigerating appliance is realized efficiently in simple structure
The substance being loaded into is dried, and proposes a kind of operation method for the refrigerating appliance.
On the one hand the task is solved by a kind of refrigerating appliance, refrigerating appliance includes storage cell compartment；With storage cell compartment point
The heat exchange chamber opened, the heat exchange chamber include heating device and can be as the heat exchangers of evaporator operation；For driving
The ventilation blower of air exchange between dynamic storage cell compartment and heat exchange chamber；With for controlling heat exchanger, ventilation blower and heating
The control unit of the operation of device, control unit support drying operational mode, in the drying operational mode ventilation blower with add
Thermal is run simultaneously.Heating device can be applied not only to give heat exchanger defrosting in this way, and for by will be hot
Amount is input in storage cell compartment and increases evaporation there.
During by replacing the heating period with cooling stage can to make in the heating period in drying operational mode from
Store the condensation and thus constantly on the heat exchanger in cooling stage then of moisture that the substance release in cell compartment goes out
It is discharged from the substance, ventilation blower is run simultaneously with heating device in the heating period, and heat is handed in the cooling stage
Parallel operation is run as evaporator with ventilation blower simultaneously.
Between heating period of the control unit by the stage of defrosting insertion cooling stage and then, add in the defrosting stage
Thermal operation, and ventilation blower is not run, to be that the frost being condensate on heat exchanger melts, and passes through the air stream of the frost
Steam cannot be delivered back into storage chamber.
When the temperature by heat exchanger, which is increased to positive value from negative value, can be inferred that heat exchanger is defrosted completely, then control
Unit processed should be transferred in the heating period from the defrosting stage, that is, run ventilation blower.
Control unit can be connect with the hygrometer being arranged in storage cell compartment, so as to according to the measurement number of the hygrometer

Limiting value is proportional to the amount of substance to be dried and the drying characteristic of the substance is specifically determined to each drying course.
This can be carried out in a simple manner, and mode is to measure the duration in the first defrosting stage of drying course, and the limit
Value is confirmed as the function of the duration, particularly is determined as the predetermined small part of the duration.Therefore
It largely can independently be ensured with the amount for the substance being encased in storage chamber, the substance in drying course progress
Water content is reduced according to the small part.
The trend of substance release water outlet is related to a number of factors, and the factor generally can be the type, such as of substance
The biological source (meat, mushroom, fruit, leafy vegetable) of the substance, preprocessing type are (such as complete, thick or fritter broken
, it is with or without box) etc..In order to assess this trend and consider to decide whether to terminate drying course, control
Unit can also connect with compartment room temperature sensor and the change speed of the temperature for detecting storage cell compartment is arranged.Change
Speed change degree can be determined as the difference between the temperature measured in predetermined time interval；Otherwise it can also measure for pre-
Given temperature changes the duration of required time, particularly heating period and/or cooling stage.Change speed to be inferred to
The amount of substance；The amount of the substance is related to the quantity gone out in cooling stage from the substance release, therefore this can be inferred that
The substance release water outlet is inclined to and the condition determined for terminating drying course can be considered.It can especially determine and remove
The limiting value of the duration in white stage is lower, then the tendency of substance release water outlet is stronger.
In order to assess the tendency of substance release water outlet, control unit can also connect with user interface and use is arranged
In the input from user interface reception user about the type for the substance being encased in storage cell compartment.
Control unit can also be connect with scale, and the scale is arranged in storage cell compartment, described be encased in storage to weigh
The weight of substance in cell compartment.The scale can simplify the drying in different ways.On the one hand, institute can continuously be monitored
The weight of substance is stated, and when weight is reduced to the predetermined small part of the initial weight of the substance, then terminates to dry
Dry process.The small part should be much, if it is known that can then be determined according to the type of substance.On the contrary, can be by
The speed that weight and weight reduce is inferred to the type of substance and suitably determines the target weight for terminating drying course.
According to a preferred configuration, heat exchanger can be in the operation as evaporator and the operation as heating device
Between switch.
For this purpose, heat exchanger can be connected in series in coolant circulating system at least one throttle point,
The percent of pass of the throttle point is controlled by control unit.

Fig. 2 shows the refrigerant-cycle systems of refrigerating appliance；With
Fig. 3 shows the flow chart of the operation method by the control unit implementation of refrigerating appliance.
Specific embodiment
Fig. 1 shows the part of the shell 1 of refrigerating appliance with schematical sectional view.Other than the chamber 2 shown completely also
One or more chambers 3 only shown to section in the accompanying drawings may be present.Chamber 2 is divided into heat exchange chamber 5 and storage by partition 4
Cell compartment 6.The heat exchange comprising that can be run as the evaporator for cooled and stored cell compartment 6 in known manner of heat exchange chamber 5
Device 7 and ventilation blower 8 for driving air stream 9, the air stream cycle through heat exchange chamber 5 and storage cell compartment 6.Compartment
Room 6 can be loaded with substance 11 to be dried.
Well known electrically driven (operated) defroster heating is mounted on heat exchanger 7.However replace preferably, heat exchange
Device 7 itself can be run optionally as evaporator or as the condenser rejected heat in heat exchange chamber 5, as
As being also described in detail later.
For the collecting tank 16 from heat exchanger discharge condensed water in the bottom of heat exchange chamber 5 below heat exchanger 7
Upper extension.Condensed water discharge pipe 17 extends to evaporating pan 18 by surrounding the thermal insulation layer of chamber 2 from the deepest point of collecting tank 16.Evaporation
Disk 18 can be arranged in the machine chamber of refrigerating appliance close to compressor 19, so as to by the waste-heat of the compressor.
Electronic control unit 10 connect with the heat-exchanger temperature sensor 12 being mounted on heat exchanger 7 and with depositing
The compartment room temperature sensor 13 put on the wall of cell compartment 6 connects.
Control unit 10 can optionally be connect with hygrometer 14, the hygrometer on the path of air stream 9 preferably
It is arranged in the inlet of heat exchange chamber 5.
It being furthermore possible to that scale 15 optionally is arranged in storage cell compartment 6, the scale can be loaded with substance 11 to be dried, with
Just the measured value of the weight of the substance is supplied to control unit 10.Scale 15 can be domestic steelyard, and the domestic steelyard also can
It is operated independently from outside refrigerating appliance and the domestic steelyard is placed in storage cell compartment 6 simultaneously just to dry substance 11
And it is connect with control unit 10.
Fig. 2 shows the refrigerant-cycle systems according to a preferred configuration of refrigerating appliance.It is exposed to outside ontology 1
Condenser 21 is connect with the coolant line 20 of the pressure interface from compressor 19 first.Pipeline 20 divides after the condenser
Branch is at two branches 22,23.Controllable first segment flow point 24, heat exchanger 7 and the second controllable throttle point 25 on branch 22
It is connected in series, and the heat exchanger 27 of one of third throttle point 26 controllable on branch 23, described chamber 3 and the controllable the 4th
Throttle point 28 is connected in series.Pipeline 20 is extended to from the point of two branches 22,23 by the evaporator 29 of other cell compartment 3
The pumping surfaces of compressor 19.Throttle point 24,25,26,28 can be expansion valve.The water conservancy diversion amount of the expansion valve can pass through control
Unit 10 processed is adjusted.
When the water conservancy diversion amount of the throttle point 24 when compressor 19 is run is low, and the water conservancy diversion amount of throttle point 25 is high,
Pressure difference is then mainly generated at throttle point 24, and the pressure in heat exchanger 7 is sufficiently low, to reach there lower than 0 DEG C
Evaporating temperature.Conversely, when throttle point 24 continue open and throttle point 25 adjust with narrowing, then the pressure in condenser 21 and
Pressure in heat exchanger 7 is substantially the same.Because heat exchanger 7 is colder than condenser 21, condense mainly in heat exchanger 7
Middle progress, and the heat discharged herein is transferred in storage cell compartment 6 by air stream 9.Cell compartment 3 of the heat from evaporator 3
It siphons away, because refrigerant evaporates there again.
Fig. 3 shows the operation method of control unit 10.In order to start drying course, user is by corresponding instruction input
(S1) user interface 30.Control unit 10 starts cooling stage S2, and mode is that throttle point 24 is switched to by control unit 10
Throttle point 25 is switched to high water conservancy diversion amount, and runs compressor 19 and ventilation blower 8 by low water conservancy diversion amount.Heat exchanger 7 is cooling
To the temperature for being lower than 0 DEG C, and cold air reaches storage cell compartment 6 from heat exchanger 7.During this period, it is aspirated from storage cell compartment
Hot-air condenses in its moisture as frost on heat exchanger 7.This dress state is kept, until compartment room temperature sensor 13 is aobvious
Show, is lower than lowest limit temperature Tmin.In order to avoid substance 11 freezes in storage cell compartment 6, lowest limit temperature Tmin should
It is chosen above 0 DEG C.
Limiting temperature is closed when being lower than, then is tested in step s3, if meets the condition for terminating drying course.Root
According to refrigerating appliance equipped with which kind of sensor, the condition be can be different, and illustrate later.
If being unsatisfactory for the condition, throttle point 24 is switched to high water conservancy diversion amount and is switched to throttle point 25 low
Water conservancy diversion amount.Compressor 19 remains operational, so that refrigerant be made to condense in heat exchanger 7, rather than evaporates.Ventilation blower 8 can
To remain operational during this period: preferably, however the ventilation blower is first shut off, so as to long-time such in defrosting stage S4
Ground heats heat exchanger 7, until heat-exchanger temperature sensor 12 shows the positive value temperature of heat exchanger 7.When being such case
When, then the frost of heat exchanger 7 melts and water is flowed out by condensed water discharge pipe 17.Then in heating period at this moment, lead to
Hot-air is blown into storage cell compartment 6 by blower 8 from heat exchanger 7.It stores cell compartment 6 and is heated in substance 11 therein,
Until being more than highest threshold temperature Tmax.The highest threshold temperature Tmax can be set or by controlling on user interface 30
Unit 10 is determined according to the type of the substance 11 inputted on user interface 30, is rapidly dried to realize, upper limit (UL)
Temperature Tmax should be able to be set higher than room temperature, preferably more than 40 or even 50 DEG C.
In the case where Fig. 3, the method is being more than that highest threshold temperature Tmax is returned directly to step S2.Alternatively,
It can examine herein, if meet the condition for terminating drying course.
In simplest situation, when there are when hygrometer 14, then termination condition is less than the limiting value of air humidity.It should
Limiting value can be differently predetermined according to the type of substance 11 to be dried and be stored in memory, control unit 10
The memory is inquired according to input information of the user for substance 11.
When not changing during multiple circulations in the method for cooling or the humidity at the end of the heating period, or
Person then can be set to when total duration of drying course reaches maximum permissible value for terminating the other of drying course
Condition.
When there are when scale 15, if the weight of substance 11 be reduced to the type advantageously according to substance 11 it is predetermined,
The small part of weight when drying course starts or the weight do not change during the circulation of the method, then
Control unit can terminate drying course.
According to a further scheme, control unit measures defrosting time, heat exchanger during defrosting stage S4
The defrosting time is needed to be heated to the temperature of a little higher than predetermined temperature for the predetermined temperature from slightly below 0 DEG C.
The time is the measurement for the frost amount gathered in cooling stage before.If the time is shorter than predetermined limiting value,
Then substance 11 can be considered as drying and terminate drying course
The amount for the substance 11 being encased in storage cell compartment 6 should be considered in the case where determining the limiting value；The amount is got over
Greatly, then frost amount is bigger, and when substance is dried to the desired degree, then frost amount yet condenses on heat exchanger 7.Cause
This, according to the second further scheme, control unit also measures the duration of cooling stage.The amount of the duration and substance 11
It is linearly related.Amount of substance, and the limiting value of defrosting time and the object are assessed by first cooling stage so can be especially
Quality is proportionally determined.
It is also contemplated that the weight loss of substance 11 is inferred to by the shortening of cooling stage during the drying process, and
And when the weight loss reaches the predetermined small part of initial weight, then terminate drying course.
It is commented according to the amount of substance of the duration of cooling stage assessment and according to the defrosting time of back to back heating period
The relationship between water estimated, control unit realize identification in storage cell compartment in substance 11 be easy or difficulty by
Drying.In the case where the substance to be dried with big surface, water loss is all big, the control in each cycle
Unit also correspondingly sets long for the limiting value of defrosting time, and described control unit terminates drying under the limiting value
Process.Protected in the substance for being difficult to dry, for example by shell so as not to dry out fruit in the case where, under identical amount of substance
The limiting value of the much shorter of defrosting time must be selected, to ensure fully to dry.
Refrigerating appliance can have to WLAN or the network interface of radio mobile communication net 31, and control unit 10 passes through described
Network interface exports signal to the smart phone of the device of networking, such as user, to prompt the user, when terminates to dry
Dry process, and substance 11 is taken out and can be substituted by fresh substance from storage cell compartment 6.
Specific App is mounted on the device of networking, so as to the signal of processing and control element (PCE) 10.The processing may be implemented
