As shown in the drawing, from be disposed at freezer about the light of illuminating part 20 output of two walls, in the irradiation refrigerating chamber 12 with being accommodated in refrigerating chamber 12 inner collecting article 33.In addition, the part from the light of this illuminating part 20 outputs incides the light quantity test section 21 that is disposed in the refrigerating chamber 12.
In the figure; In refrigerating chamber 12, take under the situation of collecting article 33; Because the existence of collecting article 33, thus show produce from about regional A, arbitrary side's area B and the arbitrary side's in the left and right sides the equal state of the zone C of crested not of light of irradiates light 34a crested of the equal crested of irradiates light 34a of illuminating part 20 of two side surface sides.
In this case, owing to be in the area B from the irradiates light 34a crested of arbitrary side's illuminating part 20, light quantity test section 21 detects corresponding light quantity and output.In addition, under the more situation of the amount of collecting article 33, because the regional A of crested increases together, the detection light quantity of light quantity test section 21 reduces.In addition, under the less situation of the amount of taking in, because all not zone C of crested increases of arbitrary side's irradiates light 34a, so the detection light quantity of light quantity test section 21 increases.
As stated, detecting the light quantity that the difference because of the amount of the existence of collecting article 33 and collecting article 33 or position causes by light quantity test section 21 changes.And, through this light quantity testing result is differentiated according to predefined defined threshold, can classify to the amount (many still few) or the position of the collecting article in the case 33.Details is of the back.
In addition, illuminating part 20 through with illumination 19 dual-purposes that are arranged at usually in the freezer 10, need not to be provided with new light source, just can infer receiving state with more simple structure.That is, also can use as illuminating part 20, the amount or the position of collecting article 33 are inferred through the illumination 19 that will be arranged in the refrigerating chamber 12.
Then, use control block diagram as shown in Figure 4, control action is described.Fig. 4 is the control block diagram of the freezer 10 in the embodiment 1 of the present invention.
As shown in the drawing, the freezer 10 in the embodiment of the present invention 1 also has collecting article and infers portion 22 and control part 23 except that above-mentioned illuminating part 20 and light quantity test section 21.
Collecting article is inferred the amount or the position of collecting article that 22 pairs in portion is accommodated in the inside of refrigerating chamber 12 and is inferred, and will infer the result and output to control part 23.Particularly, collecting article is inferred the testing result of portion 22 according to the light quantity of light quantity test section 21, and the amount or the position of collecting article are inferred.
For example; In the transitional period; In the moment of regulation, illuminating part 20 carries out luminous, under the testing result of light quantity test section 21 situation bigger than setting; Collecting article is inferred portion 22, and to infer the amount of collecting article less, and the rotating speeds that control part 23 gets into compressors 30 automatically suppress and the cold excessively constant pitch electric operations that prevent to turn round.
In addition; Under the situation below the setting, collecting article is inferred portion 22, and to infer the amount of taking in more in the testing result of light quantity test section 21, and control part 23 increases the rotating speed of compressors 30; So that in official hour, reach design temperature, enter into automatically than the high common running of economize on electricity running rotating speed.
Perhaps; Control part 23 is regulated temperature through following mode: the rotating speed of being not only compressor; Under the situation of economize on electricity running, interdict the air channel of cold air being sent into each receiving room through opening and closing structure, under the situation of running usually; To cold air being sent into the air channel of each receiving room, open the air quantity of cold air through switching mechanism control.
In addition; Below; Represented that collecting article infers the amount of 22 pairs of collecting articles of portion and infer; Control part 23 is inferred the example of the amount control cooling device 35 of the collecting article that portion 22 infers according to collecting article, but infers the position that collecting article is inferred by portion 22 for collecting article, and control part 23 is inferred the collecting article that portion 22 infers according to collecting article the situation of Position Control cooling device 35 is also identical.
Below, with reference to Fig. 5 A～Fig. 5 C, the action that the control part 23 of transitional freezer is carried out describes.Fig. 5 A～Fig. 5 C is the figure that the transitional control action that the control part in the embodiment 1 of the present invention 23 carries out is described.
In addition, after the so-called transitional period is meant and drops into collecting article, open and close behind the door leaf for a long time or the defrosting running after etc., the temperature in the freezer 10 be cooled in from the state after rising to case design temperature during.Transitional the temperature inside the box amplitude of fluctuation is generally than design temperature ± 3 ℃ big upset condition.
Particularly, Fig. 5 A has represented to carry out under the situation of the amount of taking in (below, standard) of standard the action with existing same temperature controlled control part 23.In addition, Fig. 5 B representes the action of control part 23 under the situation that the amount of taking in Duos than the standard amount of taking in, and Fig. 5 C representes the action of control part 23 under the situation that the amount of taking in lacks than the standard amount of taking in.In addition, for the ease of explanation, the kind of each collecting article is all identical.
In addition, in Fig. 5 B and Fig. 5 C, solid line is represented the detected temperatures of collecting article in the case in this embodiment, and dotted line representes to carry out the time dependence of the detected temperatures of collecting article under the situation of existing control.In addition, K0 is the storage temperature of predefined collecting article 33.Control part 23 is under the situation that the amount of taking in is Duoed than standard and under the situation about lacking than standard, infers the result of the amount of taking in the portion 22 based on collecting article, and the operating condition of cooling device 35 is switched.
In addition, Fig. 5 A is illustrated under the amount of taking in of standard, the collecting article variations in temperature the when rate of taking in the case is 50% ± 10% degree.In this embodiment, be that benchmark is controlled with this variations in temperature.It is characterized in that: the determinating reference of " standard how much " of the amount of taking in is difference owing to size, formation or the control mode of freezer, so needn't show at this.
Under the situation that the collecting article of taking in of the same race 33 is Duoed than standard, the detection light quantity of light quantity test section 21 reduces, and detects the minimizing of light quantity through this, and it is more that collecting article is inferred the amount of taking in that portion 22 infers in the case.
In this case; Shown in Fig. 5 B, in existing cooling running (dotted line), because collecting article is reduced to design temperature and need be expended time in; So control part 23 increases the rotating speed of compressor 30; Or the internal circulating load of increase cold air, automatically switch to the chilling running, so that in official hour, reach design temperature.Thus, the amount ground that can not rely on collecting article 33 reaches storage temperature in during identical with the situation of Fig. 5 A, and the amount ground that can not rely on collecting article 33 keeps the freshness of collecting article 33.
In addition, under the situation that the amount of taking in is lacked than the standard amount of taking in, the detection light quantity of light quantity test section 21 increases, and detects the increase of light quantity through this, and it is less that collecting article is inferred the amount of taking in that portion 22 infers in the case.
In this case, shown in Fig. 5 C, in existing cooling running (dotted line), occur time that collecting article reaches design temperature sometimes early, and the electric weight of consumptions more than needing cool off the situation of running.Therefore, control part 23 suppresses the rotating speed of compressor 30, or reduces the internal circulating load of cold air, automatically switches to the economize on electricity running, so that in official hour, reach design temperature.Through this action, through slowing down the temperature behavior in the case, obtain energy-saving effect, and can realize suppressing quietization such as rotary speed of cooling fan 31.
Control flow chart with Fig. 6 at length describes these actions.Fig. 6 is the flow chart that the transitional control action that the control part in the embodiment 1 of the present invention 23 carries out is described.
As shown in the drawing, at first, control part 23 judges whether to be transitional period (step 102) according to the temperature inside the box.Then, control part 23 (is Y) in the step 102 under being judged as transitional situation, carry out following control.
At first, control part 23 is used in the illuminating part 20 that carries out collecting article detection action and lights (step 103), and light quantity test section 21 detects the light quantity (step 104) that decays because of collecting article.
Then, collecting article is inferred 22 pairs of this light quantity test section 21 detected light quantities of portion and predetermined threshold value compares, and the level of the amount of taking in is judged (step 105).
Then; Collecting article infers that 22 pairs of amounts of taking in of portion are whether more judges (step 106); Under being judged to be the more situation of the amount of taking in, (be Y in the step 106), control part 23 control cooling devices 35 turn round rapidly, reach design temperature (step 107) until collecting article.
In addition, inferring portion 22 at collecting article, to be judged to be the amount of taking in be not (to be N in the step 106) under the more situation, judges (step 108) to the amount of taking in is whether less.Then, infer portion 22 at collecting article and be judged to be under the less situation of the amount of taking in (being Y in the step 108), the running of economizing on electricity of control part 23 control cooling devices 35 reaches design temperature (step 109) until the amount of taking in.
In addition, inferring portion 22 at collecting article, to be judged to be the amount of taking in be not (in step 108, to be N) under the less situation, and control part 23 judges that the amounts of taking in are standard (step 110), and control cooling device 35 carries out common cooling running (step 111).
Then, use Fig. 7 A～Fig. 7 C, passed through adequate time to dropping into collecting article, the action of the control part 23 of the freezer the during temperature stabilization of collecting article describes.Fig. 7 A～Fig. 7 C is the figure that the control action of stationary phase that the control part in the embodiment 1 of the present invention 23 is carried out describes.
Be meant stationary stage, through the transitional period, after the temperature of collecting article reaches design temperature, the ON/OFF action through the cooling running etc., make the temperature of collecting article keep certain during.The change in the scope of ± 3 ℃ of degree usually of the temperature inside the box of stationary phase.
Particularly, Fig. 7 A representes to carry out under the situation of the amount of taking in (below, standard) of standard the action of the temperature controlled control part 23 identical with prior art.In addition, Fig. 7 B representes the action of the control part 23 of the situation that the amount of taking in is Duoed than standard, and Fig. 7 C representes the action of the control part 23 of the situation that the amount of taking in is lacked than standard.At this, in stationary stage, with cycle T repeatedly between cooling period and stand-down ground cool off.
Under the situation of taking in the collecting article of the same race of Duoing than standard, the detection light quantity of light quantity test section 21 reduces, and detects the minimizing of light quantity through this, and it is more that collecting article is inferred the amount of taking in that portion 22 infers in the case.
In this case, according to the total of the thermal capacity of collecting article, the thermal capacitance quantitative change in the case is big, so the cold insulation ability increases, temperature rises and slows down.Therefore, elongated between cooling period and stand-down shown in Fig. 7 B, to compare during with the standard amount of taking in, cycle T is elongated.
Like this, because the thermal capacity that the collecting article of the state of cooling has played through self makes the temperature inside the box keep the effect of low temperature, K0 compares with design temperature, and the mean temperature K1 of collecting article is in low temperature, promptly becomes " cold excessively ".
Therefore, in this case, control part 23 control cooling devices 35 exceed 1～2 ℃ K2 so that design temperature becomes than K0.Thus, suppress the cold excessively of collecting article and since the temperature of collecting article self remain with design temperature K0 basis about equally on suppress the cooling running, so can be in the state that keeps quality minimizing consumes electric power down.
In addition; The design temperature of K2 is preferably than the rise temperature of " K0-K1 " degree of K0, but as stated, as predefined temperature amplitude; Exceed 1～2 ℃ temperature if be set at, then can prevent because of the rise quality reduction etc. of the collecting article that causes of suddenly temperature.
In addition, under the situation that the amount of taking in is lacked than the standard amount of taking in, the detection light quantity of light quantity test section 21 increases, and detects the increase of light quantity through this, and it is less that collecting article is inferred the amount of taking in that portion 22 infers in the case.
In this case, because collecting article is less, even add up to the thermal capacity of collecting article, the thermal capacity in the case is still less, thus the cold insulation ability a little less than, can produce the temperature tendency faster that rises.And, because thermal capacity is less, so the temperature of collecting article self is followed cooling and reduced fast.
Therefore, shown in Fig. 7 C, shorten between cooling period and stand-down, compare cycle T when taking in and shorten, and the temperature of collecting article self has and remains and design temperature tendency much at one with standard.
In this case, under the situation of identical cooling control, shown in Fig. 7 C, the interval between cooling period and stand-down shortens when carrying out with standard, owing to need frequently carry out air channel control, produces error.Therefore, control part 23 for example delays cooling through reducing amount of cooling water in order to realize further energy-conservationization, controls so that become between cooling period and stand-down identical with common running.
In addition, control part 23 is as the mechanism that reduces amount of cooling water, reduces sometimes or stops the rotating speed of cooling fan 31 and reduce air quantity, or reduce the running rotating speed or the running rate of compressor 30.
Thus, can be set between the cooling period and stand-down identical, and realize the minimizing of the consumes electric power of economize on electricity running with common running.
For the details of these actions, the control flow chart through Fig. 8 describes.The flow chart that Fig. 8 describes for the control action of stationary phase that the control part in the embodiment 1 of the present invention 23 is carried out.
As shown in the drawing, at first, control part 23 judges whether to be stationary phase (step 202) according to the temperature inside the box.Then, control part 23 (being Y in the step 202) under being judged as the situation of stationary phase carries out following control.
At first, control part 23 is used in the illuminating part 20 that carries out collecting article detection action and lights (step 203), and light quantity test section 21 detects the light quantity (step 204) that decays because of collecting article.
Then, collecting article is inferred portion 22 these light quantity test section 21 detected light quantities and predetermined threshold value is compared, and the level of the amount of taking in is judged (step 205).
Then, collecting article infers that 22 pairs of amounts of taking in of portion are whether more judges (step 206), under being judged to be the more situation of the amount of taking in, (is Y in the step 206), and control part 23 control cooling devices 35 make design temperature rise to the temperature K2 (step 207) higher than K0.
In addition, it is not (to be N in the step 206) under the more situation being judged to be the amount of taking in that collecting article is inferred portion 22, and the amount of taking in is judged to be standard or less (step 208).Then, control part 23 control cooling devices 35 carry out the common cooling running or the economize on electricity running (step 209) of minimizing amount of cooling water.
As stated, in the freezer 10 of this embodiment, have: freezer main body 11; Cooling device 35 with cooling in the freezer 10; Be disposed at the assigned position in the freezer 10, have in the irradiation freezer 10 at least more than one the illuminating part 20 of light source of the collecting article 33 inner with being accommodated in freezer 10; Be disposed in the freezer 10,, detect light quantity test section 21 by the light quantity of illuminating part 20 irradiations via collecting article 33 and the works in the freezer 10; Based on the testing result of light quantity test section 21, the collecting article that infer the amount or the position of collecting article 33 is inferred portion 22; Control cooling device 35 with the amount of the collecting article 33 of inferring portion 22 according to collecting article or the result that infers of position, control the temperature inside the box becomes the control part 23 of the temperature setting of regulation.
Thus; From the testing result of light quantity test section 21 amount or the position of collecting article 33 are inferred; Correspondingly suitably control freezer 10 with it; Regardless of the amount or the position of collecting article 33, can both preserve collecting article 33 thus, high-preserved property can be provided and economize electrically high freezer 10 with roughly the same preservation condition.
That is,, under the temperature of purpose, preserve collecting article 33, can realize the high-preserved property of collecting article 33, simultaneously,, can suppress consumes electric power through preventing " cold excessively " of collecting article 33 through regardless of the situation of taking in the case.In addition, through the light that light quantity test section 21 receives from light source irradiation such as LED, can realize the amount of collecting article 33 or inferring of position with simple structure.

Then, the functional structure to the freezer 10c in this embodiment 4 describes.
Figure 13 is the control block diagram of the freezer 10c in this embodiment 4.
As shown in the drawing, the freezer 10c in the embodiment 4 replaces the light quantity test section 21 of the freezer 10 in the embodiment 1 as shown in Figure 4, has spatial detection portion 26, and has identification part 27.
Promptly; Shown in figure 12; Spatial detection portion 26 has 26a of spatial detection portion and the 26b of spatial detection portion; The 26a of spatial detection portion detects the size of the spatial volume of the periphery of cold gas exhausting outlet 4a at least, and the 26b of spatial detection portion detects the size of the spatial volume of the periphery of cold gas exhausting outlet 4b at least.
Collecting article is inferred the testing result of portion 22 according to spatial detection portion 26, and the amount or the position of collecting article 33 are inferred.
For the freezer 10c that as above constitutes, describe in the face of its action down.
At first, under the state of door leaf 108, light illumination 19 in closure.Upper strata above accepting rack 18a arrives the 26a of spatial detection portion of the illumination of the accommodation space that detects the superiors via air from illumination 19 light.
Intermediate layer between accepting rack 18a and accepting rack 18b through between the collecting article 33, arrives the 26b of spatial detection portion of the illumination of the accommodation space that detects the second layer from the part of illumination 19 light.Owing to run into collecting article 33 and absorbed by collecting article 33 from another part of illumination 19 light, reflection takes place and scattering takes place in a part, so promptly forming the rear side of the collecting article 33 of shade with illumination 19 opposition sides of collecting article 33, the amount of light reduces and deepening.
This be because, the height of collecting article 33 is high more, or the amount of taking in of collecting article 33 is many more, can cover illumination 19 light more, the amount of light that arrives the 26b of spatial detection portion that is in the rear is then low more.
Then; Like this; Detect the amount of light with the 26a of spatial detection portion, 26b, will be with respect to the middle level of accepting rack 18a below, there is the situation in the space that can take in to be shown in to be in the not shown display part as the outer surface of the refrigerating-chamber door 12a of door leaf in the upper strata above accepting rack 18a.That is, the state of the collecting article in user's refrigerating chamber 12 is informed through being that the outer surface of the refrigerating-chamber door 12a that installs of the front surface side of refrigerating chamber 12 shows at the storeroom with the 26a of spatial detection portion, 26b in identification part 27.
