It is that inside is formed with rearward gradually toward the inclined inclined surface 20a in lower section at the rear portion of spacer member 20.Also, incline
It is formed with opening portion 22 on inclined-plane 20a, pressure fan 23 is equipped in opening portion 22.
Since pressure fan 23 is configured at inclined surface 20a, the rotary shaft of fan 23a is not vertical, to
The front-rear direction of the refrigeration equipment 1 of refrigerating function tilts.Specifically, in pressure fan 23, blowing direction, that is, fan 23a's blows
The rotary axis direction of wind side downward, and is tilted and is configured forwards.
In the following, it is based on flow chart shown in fig. 6 and sequence diagram shown in Fig. 7, and while with reference to above-mentioned each figure, to this reality
Apply the refrigeration equipment 1 with supercooling function of mode by supercooling operate when centered on illustrate.Herein, it acts below
It is controlled by the CPU30 as control mechanism.In addition, in Fig. 7, top indicates that curve graph, lower part indicate sequence diagram.On top
In curve graph, horizontal axis indicates to pass through the time, and the longitudinal axis indicates freezer temperature and 34 displays temperature of temperature testing organization.In addition, should
In curve graph, the surface temperature for being frozen object 26 that temperature testing organization 34 as shown in Figure 4 detects is represented by dashed line, upper layer
The indoor temperature of freezing chamber 5 is indicated with chain-dotted line.
First, in being operated to the common cooling carried out in step slo, the flowing of cold air illustrates.Reference Fig. 4,
In usual cooling operating, the part for being sent to the cold air of supply wind path 14 by pressure fan 32 from cooling chamber 13 passes through blowing mouth
28 flow into upper layer freezing chamber 5.In addition, as already explained above, in usual cooling operating, supplying one of the cold air in wind path 14
Divide supply ice-making compartment 4（With reference to Fig. 2）While with lower layer freezing chamber 6, by supplying the supply of wind path 15 to refrigerating chamber 3.
The cold air flowed into from supply wind path 14 mainly flows into upper layer freezing chamber 5 from opening portion 22.In addition, from supply wind path 14
A part for the cold air of inflow flows into upper layer freezing chamber 5 by communication port 21.Herein, when usual cooling, it is configured at interval
The pressure fan 23 of the opening portion 22 of component 20 is inoperative, but cold air passes through the periphery of the pressure fan 23 in halted state.For
It is flowed into the lower layer's freezing chamber 6 being located at below to the cold air of upper layer freezing chamber 5.The common cooling operating is until supercooling is transported
When turning, i.e. in the case of the NO of step S11, continuously carry out.
In addition, in the case of above-mentioned usual operating, output of the control mechanism based on thermometer makes to be included in freeze cycle
In 31 intermittent running of compressor.Specifically, with reference to Fig. 2, in either one or two of refrigerating chamber 3, freezing chamber 4A and vegetable compartment 7 or
Thermometer (not shown), the output based on the thermometer are configured in multiple, control mechanism makes compressor 31 intermittently operate.By
This, refrigerating chamber 3, freezing chamber 4A and vegetable compartment 7 are maintained at defined temperature region.
In the following, in the case that step S11 is YES, user press operation that operation panel 27 shown in FIG. 1 has by
Button etc. and start supercooling operating.On the other hand, in the case that user does not press the operation button, step S11 is NO, supercooling
Operating does not start.
At this point, being frozen object 26 stores upper layer freezing chamber 5 shown in Fig. 4.But in the present embodiment, as quilt
It is several kilograms food meat etc. that frozen material 26, which can use weight,.This large-scale object 26 that is frozen is passed through supercooling by ordinary circumstance
But state freeze being very difficult.But in the present embodiment, by using cooling means described below, pass through
Supercooling state freezes to be frozen object 26.
If supercooling operation start, during step S12 is NO, stipulated time α is waited for.Herein, it is specified that when
Between α be such as 20 seconds.Also, step S12 becomes YES, is converted to step S13 when have passed through stipulated time α.
In step s 13, forbid defrosting.Herein, defrosting action is illustrated.Specifically, with reference to Fig. 2, when after
Continuous when carrying out cooling operating, frost attachment on the air side heat-transfer area of cooler 33 interferes heat transfer, blocks air flow circuit.Therefore, it controls
Mechanism processed judges frosting from the reduction etc. of refrigerant evaporating temperature, starts the defrosting of the frost removal for that will be attached to cooler 33
Operating.In the case of carrying out defrosting operating, control mechanism stops the operating of compressor 31 and pressure fan 32, by wind path shutter 18
It is closed.Also, control mechanism is powered to Defrost heater 19.Then, since the fever of Defrost heater 19 is adhered to
Melt in the frost in cooler 33 and cooling chamber 13.Flow after frost melts drops down onto evaporating pan (not shown).The defrosting stroke knot
After beam, control mechanism again operates compressor 31 and pressure fan 32, to 5 cool-air feed of upper layer freezing chamber.
In the stroke that defrosts, as it appears from the above, because compressor 31 stops, it, can not during carrying out defrosting stroke
By cool-air feed upper layer freezing chamber 5, it can worry that the temperature control of upper layer freezing chamber 5 is unstable.In addition, in the stroke that defrosts, by
In heating the air inside cooling chamber 13 by Defrost heater 19, the temperature control of upper layer freezing chamber 5 can be also worried as a result, not
Stablize.In the present embodiment, the step after step S13, by forbidding the stroke that defrosts, to make compressor 31 continuously
Operating, can be continuously by cool-air feed upper layer freezing chamber 5.In addition, because by forbidding the stroke that defrosts, to Defrost heater
19 do not generate heat, so, upper layer freezing chamber 5 will not be influenced by the heating of Defrost heater 19.Therefore, in order to realize supercooling
State can correctly control the temperature of upper layer freezing chamber 5.
In step S14, start the temperature detection for being frozen object 26.I.e. with reference to Fig. 4, will show by temperature testing organization 34
The display detected is frozen the information input control mechanism of the temperature of object 26.Since temperature testing organization 34 is far infrared temperature
Degree meter, therefore, temperature testing organization 34 detects the temperature being frozen near the surface of object 26.
In the case that step S15 is NO, set in advance by the temperature for being frozen object 26 that temperature testing organization 34 detects
It is more than fixed temperature ss.Herein, β is preset first temperature, is set to such as -3 DEG C.Therefore, control mechanism convert to
Step S16, while being frozen the temperature of object 26 by the detection of temperature testing organization 34, in order to keep present situation intermittent running compressor
31, gradually cooling is frozen object 26.In the present embodiment, during being frozen the temperature of object 26 more than temperature ss, by
It has a rest operating compressor 31, to inhibit cooling capacity, do not make the temperature for being frozen object 26 reduces too fast.
On the other hand, in the case that step S15 is YES, the temperature for being frozen object 26 that is detected by temperature testing organization 34
Less than predetermined temperature β.In this case, to step S17, control mechanism makes compressor 31 continuously run for conversion.In Fig. 7
Sequence diagram in, indicate that compressor 31 continuously runs the time of beginning with T11.
With reference to Fig. 2, control mechanism is by making compressor 31 continuously operate, to be cooled down in cooling chamber 13 by cooler 33
The air in portion.In addition, simultaneously, control mechanism makes pressure fan 32 also continuously operate, it is cold by being cooled down in the inside of cooling chamber 13
Gas supplies upper layer freezing chamber 5.As a result, with reference to Fig. 4, the object 26 that is frozen to being stored in upper layer freezing chamber 5 continuously feeds cold air.
The cooling cooling capacity for being frozen object 26 increases as a result,.
Herein, in step S17, control mechanism makes compressor 31 continuously operate, and still, pressure fan 23 is made not transport
Turn.The reason for this is that in order to inhibit cooling capacity in this step, the temperature for being frozen object 26 is not made to reduce too fast.
In the following, in the case that step S18 is NO, the temperature detected by temperature testing organization 34 is in predetermined temperature γ
More than.Herein, γ is preset second temperature, is less than the temperature of above-mentioned β.The occurrence of γ is set to such as -4.5
℃.In this case, control mechanism is converted to step S19, in order to keep present situation, object 26 is frozen by the detection of temperature testing organization 34
Temperature while, so that compressor 31 is continuously run, cooling be frozen object 26.
On the other hand, in the case that step S18 is YES, the temperature for being frozen object 26 that is detected by temperature testing organization 34
Less than temperature γ.In this case, to step S20, control mechanism makes pressure fan 23 continuously run for conversion.In the sequence diagram of Fig. 7
In, indicate that compressor 31 continuously runs the time of beginning with T12.
Specifically, in this step, control mechanism makes 31 continuous action of compressor, also, is that pressure fan 23 is continuously transported
Turn.Therefore, with reference to Fig. 5 A and Fig. 5 B, pressure fan 23 is made to operate by control mechanism, to blow cold air to object 26 is frozen.This
Outside, while a part for the cold air blown by pressure fan 23 is recycled via wind path 40,41,42,43, cooling is frozen object
26。
In this way, while making compressor 31 operate by control mechanism, pressure fan 23 is set also to operate, so as to make to quilt
The air quantity for the cold wind that frozen material 26 supplies increases, and the surface temperature for being frozen object 26 is made to reduce rapidly.It is frozen object 26 in freezing
In the case of, it is most suitable to make entirely to be frozen object 26 supercooling occurs, but it is such as several kilograms or so to be frozen object 26
Meat piece in the case of, make until the center portion thereof distribution it is raw cooled be very difficult.Even if in this case, according to this
Embodiment, by the way that supercooling occurs near the surface for being frozen object 26, watery blood when so as to inhibit to thaw is lost in.
In the case that step S21 is NO, preset by the temperature for being frozen object 26 that temperature testing organization 34 detects
Temperature delta more than.Herein, δ is preset third temperature, is less than the temperature of above-mentioned γ.The occurrence of δ is set to example
Such as -20 DEG C.Therefore, to step S22, control mechanism judges whether it is to start to have passed through the stipulated time after supercooling operating for conversion
ε。
On the other hand, if the temperature for being frozen object 26 detected by temperature testing organization 34 is less than temperature delta, due in step
It is judged as YES in rapid S21, therefore, is judged as that be frozen object 26 is cooled completely, conversion to the step S24 for allowing defrosting step.
In addition, if stipulated time ε is have passed through, and since judgment step S22 is YES, conversion to permission defrosting step
Step S24.Herein, it is as an example 25 hours.On the other hand, in the case where not passing through stipulated time ε, due to step
Rapid S22 is NO, and therefore, conversion to step S23, control mechanism keeps present situation.That is, by making compressor 31 continuously run, to
Cooling cold air is blowed to by pressure fan 23 and is frozen object 26.
In step s 24, judge that being frozen object 26 has been cooled, license carries out defrosting step.That is, by using above-mentioned side
Method is removed by heating Defrost heater 19 to be attached to the frost dissolving on 33 surface of cooler.
Later, conversion terminates supercooling operating, conversion to usual cooling operating to step S25.That is, with reference to Fig. 2, control
