Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a case for storing fresh food.

[0002]

2. Description of the Related Art Conventionally, this type of material case has been installed at the counter of a sushi restaurant, a restaurant, etc. so that customers can see the sushi material (seafood) etc. stored inside. For example, Japanese Utility Model Laid-Open No. Sho 63-159175 (F25D 19
/ 00), a refrigerating chamber is formed which extends in the left-right direction on a heat insulating wall serving as a bottom wall and surrounds a front plate, an upper surface, and a rear plate with transparent glass. A machine room is constructed on the side of the room, a cooler that constitutes a refrigeration cycle together with a compressor in the machine room is installed above the refrigeration room, and it is known that the refrigeration room is cooled by natural circulation of cold air. There is.

Further, as a method of mounting the temperature sensor, as shown in JP-A-5-248754, a method of detecting the temperature by exposing the temperature sensor inside the heat insulating box is generally used.

[0004]

In the prior art of Japanese Utility Model Laid-Open No. 63-159175 described above, the position of the sensor is unclear, and this low temperature showcase is disclosed in JP-A-5-248754.
If the temperature sensor is installed as shown in No. 6, it is a showcase installed at counters such as sushi restaurants and Japanese-style restaurants, and the temperature detection part of the sensor is visible to the customer, which may impair aesthetics. .

Further, in a net case having an open upper part as shown in the present invention, a natural convection type is generally adopted, and the temperature detecting portion of the sensor directly measures the temperature inside the refrigerator. For example, when a sensor is installed in the upper part of the inside of the refrigerator, the compressor is repeatedly started and stopped each time the door is opened and closed, so the temperature rise at the bottom of the inside where the stored food is actually placed There is a problem that the compressor is activated to excessively cool the stored food although it is scarce.

Further, in this type of case, there is a case where a cold storage member such as ice is spread on the bottom of the inside of the refrigerator and the stored food is placed on it. This is a method that is used in order to increase the aesthetic appearance and enhance the customer's appetite because the inside of the material case can be seen by the customer due to the structure of the equipment and to prevent the material from drying out by keeping the humidity in the refrigerator high. When the above method is adopted, that is, when ice is spread in the refrigerator, there is a problem that the temperature of the ice is detected when the sensor is installed at the bottom, and the temperature detection part of the sensor freezes. Even problems will occur. If the sensor freezes, the temperature inside the refrigerator cannot be controlled, causing a problem.

The present invention has been made in view of the above-mentioned problems, and provides a news item case for the purpose of stably controlling the temperature inside the refrigerator.
