Above, the cooling running control based on storage situation detection result is illustrated, then, controls to be described to the storehouse intraoral illumination mated with the storage situation in storehouse.

Figure 13 is the LED control flow chart of the storehouse intraoral illumination of the freezer of the 1st embodiment of the present invention.Figure 14 is the LED output characteristics figure of the storehouse intraoral illumination of the freezer of the 1st embodiment of the present invention.Figure 15 be the freezer of the 1st embodiment of the present invention storehouse in the illustraton of model of illumination.

Lightness in storehouse changes according to storage situations such as storage amount and storage places, therefore, by the output set point change etc. such as making near upper strata that storage amount is few and near lower floor that storage amount is many illuminating part 20, storehouse intraoral illumination is made to control change according to the storage situation of accommodation space, the twinkling minimizing etc. at night can be made, realize best visibility.

Below, Figure 13 ~ Figure 15 is used to be described its action, effect.

First, the storage condition detection of the flow process by Fig. 6 is above controlled to the upper strata storage amount obtained, utilize the division scope specified by storage situation estimation portion 23 to judge, be categorized as " many ", " lacking ", " not having " these 3 regions (step S140).When being divided into " many ", by illuminating part 20a, 20b that the upper layer side at Lighting Division 19 is arranged, the output setting of (below referred to as upper layer side LED) is stored in storage part 64 as 100%.Equally, when being divided into " lacking ", the output of illuminating part 20a, 20b setting is stored in storage part 64 as 50%.When being divided into " not having ", the output of illuminating part 20a, 20b setting is stored in (step S141) in storage part 64 as 20%.

Then, the lower floor's storage amount detected is categorized as in the same manner as upper strata storage amount " many ", " lacking ", " not having " these 3 regions (step S142).When being divided into " many ", the output setting of illuminating part 20c, 20d (below referred to as lower layer side LED) of being arranged by the lower layer side at Lighting Division 19 is stored in storage part 64 as 100%.Equally, when being divided into " lacking ", the output of illuminating part 20c, 20d setting is stored in storage part 64 as 50%.When being divided into " not having ", the output of illuminating part 20c, 20d setting is stored in (step S143) in storage part 64 as 20%.

Then, illuminance transducer 72 outside the storehouse shown in Fig. 4 is utilized to measure the illumination (step S144) being provided with the surrounding environment of freezer main body 11.Then, the value of this ambient illuminance and regulation compared, when illumination is greater than the value of regulation around (being such as more than 5 luxs), when being judged as the i.e. daytime of becoming clear movable, the LED previously determined exports setting value and does not change and maintain.In addition, when illumination is less than the value of regulation around (being such as less than 5 luxs), be judged as the h.d. at dark i.e. night, make LED export setting value and be 0.5 times and change to setting that output is reduced and be stored in (step S145) in storage part 64.
