According to one first embodiment of the present invention, a light-sensitive element is installed, on the outer surface of refrigerating equipment so that the luminous intensity in the direct detection refrigerating equipment environment.This light-sensitive element preferably is arranged on the control panel of refrigerating equipment, this control panel fellow disciple form together refrigerating equipment appearance and thereby also expose to the open air under ambient light intensity, this ambient light intensity the time is also injected in the inner room of refrigerating equipment at the door of opening refrigerating equipment.It is desirable that such light-sensitive element is settled, because this allows to realize at low cost that light-sensitive element is with the wiring of affiliated control circuit and finish the wiring of other executive component simultaneously.
Second embodiment of the invention, light-sensitive element is placed in the inner room of refrigerating equipment, so it exposes to the open air under the compound exposure intensity of inner room illuminator and surround lighting (opening under the situation of door).This embodiment especially allows to regulate the power of inner room illuminator according to the door open degree or according to the degree that the user who stands in the place ahead shelters from inner room.
In the above-described embodiment, this light-sensitive element and control circuit and inner room illuminator connect into a unit, and this unit can be used as a prefabricated component and is installed in the inner room.The installation cost of such element can not be higher than the installation cost of traditional inner room illuminator.
This control circuit preferably is equipped with the governor motion of a brightness value that is used to regulate surveyed and the correlation between the inner room illuminator power.By the adjusting of this governor motion, the user can make the control circuit state be adapted to his human needs.Therefore, for example can control like this, promptly the inner room illuminator power of being set up by control circuit replenishes the luminous intensity of injecting from the outside, does not always obtain basicly stable constant brightness thereby can rely on ambient brightness ground in inner room.That is to say that power and the ambient brightness set up by control circuit change variation on the contrary; But also can consider the inner room illuminator power adjusting synchronous with ambient brightness, its purpose is, can obtain a brightness that is directly proportional with ambient brightness to a certain extent in inner room.In other words, if the room that wherein is placed with refrigerating equipment is for example shone especially brightly because of direct Exposure to Sunlight and user's eyes when being adapted to such illumination intensity, higher illumination intensity when then he need have to check refrigerating equipment than him under dim environment in this refrigerating equipment in order cosily to find the article in the refrigerating equipment.
Description of drawings
Other features and advantages of the present invention are seen with reference to the accompanying drawings the explanation to several embodiment did.Accompanying drawing is represented:
A schematic cross-sectional views of the refrigerating equipment that Fig. 1 the present invention proposes;
Fig. 2 P/I-characteristic curve
The housing front view that Fig. 3 inner room illuminator is second embodiment of the invention used.
The specific embodiment
Fig. 1 represents a schematic cross-section according to the refrigerator of first embodiment of the invention.Above refrigerator doors 1, a control panel 2 on the refrigerator front surface, on this control panel, be provided with various, unshowned in the drawings and as be used in the regulating part and the indication piece of room temperature.A control electronic device 3 is installed in the back of control panel 2, and what be attached thereto has various operating parts and an indication piece, and this control electronic device for example press traditional approach and regulated (unshowned) refrigerant cycle and move.
In the back of a light inlet window of control panel 2, as light-sensitive element a photodiode 4 is housed, this photodiode provides one to the representational photoelectric current of the brightness in refrigerator environment to control electronic device 3.
In addition, control electronic device 3 also with a switch 5 that is used to grasp the keying of refrigerator doors 1.When switch 5 expression refrigerator doors 1 open mode, then to control electronic device 3 and electric current is provided for inner room illuminator 6, it regulates current power according to the photoelectric current of photodiode 4.The example that is used for the adjusting action of feasible control electronic device 3 is the indicatrix that is used for the output power P of inner room illuminator as shown in figure, this output power and the intensity of ambient lighting or the intensity of photoelectric current I is relevant more precisely.Under the situation of ambient brightness very little (I is bordering on 0), the current power P that supplies with inner room illuminator 6 is the rated power Pmax (P maximum) of the illuminator of inner room illuminator 6; I improves constantly along with ambient brightness, and power P constantly reduces, and is last, and when ambient brightness had reached such value, promptly ambient brightness when also being enough to throw light on the refrigerator inner room this moment, and this power reaches 0 value.
Curve b represents an opposite control behavior: if ambient brightness very little (I is bordering on 0), then the refrigerator inner room is at first with small-power P
MinThrow light on, along with brightness constantly increases, lighting power also increases, and reaches rated power P at last up to it
Max, inner room illuminator 6 is this rated power design.What this adjusting was considered is: under the low situation of ambient brightness, user's eyes are general to adapt to a kind of like this brightness, thereby too strong inner space illumination can make him dizzy, and on the contrary, in a very bright environment, may wish has very bright inner room illumination.
Any meeting in the end of falling in these two kinds of control strategies is thought more comfortable and more suitable by the user, this may depend on user's custom and refrigerator arrangement environment.Therefore, a governor motion is set suitably, this governor motion provides a possibility of selecting for the user between the control strategy by curve a or b, and perhaps it allows to realize the stepless transition adjusting between two curves shown in the dotted line of Fig. 2.
