Abstract

(57) [Summary] [Purpose] To improve the safety and reliability by making it possible to confirm the rough operating condition of the freezer with the display lamp. [Structure] Inspection lamp 5 that lights up when the temperature inside the chamber rises above -8 ° C, normal operation lamp 6 that lights up below that temperature, and lights up when the freezing switch 7 is pressed to switch to freezing operation. The freezing lamp 8 is provided to automatically switch to the normal operation after a lapse of a certain time after the start of the freezing operation.

Description

[Detailed description of the device]

[0001]

[Industrial application]

 The present invention relates to a freezer used exclusively for freezing.

[0002]

[Prior Art]

 In a conventional freezer of this type, although there is a means for displaying the internal temperature, it is generally not provided with a means for roughly indicating what kind of operating condition it is in.

[0003]

[Problems to be solved by the device]

 In the conventional freezer, even if the temperature inside the refrigerator fluctuates to some extent, the internal freezing state is apparently the same, so it is possible to roughly determine the operating state. There is a problem that it is difficult to grasp.

An object of the present invention is to provide a freezer with high safety and high reliability, which allows the internal operating state to be roughly confirmed from the outside.

[0005]

[Means for Solving the Problems]

 A freezer according to the present invention for achieving the above-mentioned object is provided with an inspection lamp which is turned on when the temperature inside the refrigerator exceeds a temperature at which freezing cannot be guaranteed, and an illumination lamp which is turned on when the temperature falls below the above temperature It is characterized by having an operation lamp and a freezing lamp that lights up when the normal operation is switched to the freezing operation.

[0006]

[Action]

 In the freezer with the above-mentioned configuration, the normal operation lamp is always lit when the internal temperature is kept at the normal freezing temperature, and both the normal operation lamp and the freezing lamp are lit during freezing operation. When the temperature exceeds the temperature that cannot guarantee freezing, only the inspection lamp lights up to inform the user of the abnormal condition.

【Example】

 The present invention will be described in detail with reference to the illustrated embodiment. FIG. 1 is a sectional view of an embodiment of a freezer according to the present invention, and FIG. 2 is a sectional view in a direction perpendicular to the section of FIG. Reference numeral 1 denotes a freezer main body, a freezing machine room 2 having a freezing machine built therein is provided at a bottom portion on one side thereof, and a fan 3 is provided inside the freezer main body 1 at a position corresponding to an upper side of the freezing machine room 2 at a wall surface portion. Has been deployed towards. Reference numeral 4 denotes a lid that opens and closes the upper opening of the freezer main body 1.

FIG. 3 is a perspective view of the freezer main body 1 and the lid 4 as seen from the outside. 5 is an inspection lamp, 6 is a normal operation lamp, 7 is a freezing switch, and 8 is a freezing lamp.

Further, in FIGS. 1 and 2, reference numeral 9 denotes a basket suspended from the upper opening of the freezer main body 1, and a single basket or a plurality of baskets are suspended laterally. Reference numerals 10 and 11 denote food items stored in the freezer main body 1 or the basket 9. The cooling pipe 12 drawn out from the freezer machine room 2 is arranged over the entire wall surface inside the freezer main body 1. The fan 3 is provided so as not to interfere with the lateral movement of the basket 9, that is, at a position where it does not contact the bottom of the basket 9.

In the above configuration, for example, a normal operation for cooling the inside of the freezer main body 1 to a temperature of around −20 ° C. and a freezing operation for cooling to a temperature of around −30 ° C. can be switched by pressing the freezing switch 7. The fan 3 works only during freezing operation.

Further, when the temperature inside the refrigerator exceeds a temperature at which complete freezing of food cannot be guaranteed, for example, −8 ° C., the inspection lamp 5 is turned on to warn the user. This guaranteed limit temperature is a temperature at which the temperature does not rise any more even when the lid 4 is opened and the food items 10 and 11 are put in and taken out, and it has been experimentally obtained. When the inspection lamp 5 is lit, the freezer breaks down. You can judge that

When the inside temperature becomes lower than the guaranteed limit temperature, the normal operation lamp 6 is turned on. During normal operation when the temperature inside the refrigerator is around -20 ° C, even if the fan 3 does not operate, the temperature distribution inside the refrigerator is almost uniform, so frost is concentrated on a part of the inside of the refrigerator. There is nothing to do.

When the freezing switch 7 is pressed to switch from the normal operation to the freezing operation, the fan 3 is interlocked with the freezing operation to move the air in the refrigerator to the wall surface where it is most cooled, as shown by the arrow in FIG. Spray directly toward you. The air blown to the wall surface portion is cooled by the cooling pipe 12 of the wall surface portion and circulated throughout the inside of the refrigerator along the wall surface portion, so that the temperature distribution inside the refrigerator is uniformly equalized, and in a short time. Freezing temperature is reached.

The freezing lamp 8 is lit while the freezing operation continues, and is automatically switched to the normal operation when a fixed time, for example, 24 hours has elapsed after the start of the freezing operation. During the freezing operation, the fan 3 operates to uniformize the temperature distribution inside the refrigerator, which prevents frost from concentrating on a part of the refrigerator.

[0015]

[Effect of the device]

 As described above, in the freezer according to the present invention, the internal operating state can be roughly checked from the outside by the lamp, and when the abnormal temperature cannot guarantee the freezing, the user can be informed by the inspection lamp. By notifying, safety and reliability can be enhanced.
