Problems solved by technology

However, the former is indirectly cooled by the return air temperature of the refrigerated room, and the temperature will rise due to opening and closing of the door, and the desired cooling effect cannot be obtained. For this, a special structure and extra space such as a hollow cooling room are required, but its complex and costly
And, the latter is in order to keep the temperature in the refrigerator at a low temperature of 1°C and suppress the intense respiration, so an evaporator is provided around the outer box for cooling, and a fan is arranged in the inner box separated by an air layer to make the inner box The temperature is fixed, and this structure has the problem of requiring a large-scale device
In addition, there is a problem of promoting drying due to the need to move cold air

Embodiment 1

[0047] Embodiments of the refrigerator of the present invention are described below with reference to the drawings. In addition, the same code|symbol is attached|subjected to the same part, and the repeated description is abbreviate|omitted. Fig. 1 is an example of an embodiment of the refrigerator according to the present invention, and is an explanatory diagram of a vegetable compartment of the refrigerator. Symbol 1 represents the main body of the refrigerator. The refrigerator 1 includes a refrigerating room 100 disposed at its uppermost portion and provided with an opening and closing door. Below the refrigerating room 100, a temperature zone that can be switched from a freezing temperature zone (-18° C.) to refrigerating, vegetable, and cooling is provided. The transition room 400 with a sliding door, the ice-making room 500 with a sliding door arranged side by side with the transition room 400, the freezing room 200 arranged at the bottom and having a sliding door, bet...

Embodiment 2

[0060] Figure 12 It is an example of another embodiment of the refrigerator of the present invention, which is shown in Fig. 1- Figure 4 Side sectional view of illustrated vegetable compartment diagram. Reference numeral 301 denotes a vegetable box arranged in the vegetable compartment 300, and reference numeral 302 denotes a fruit box slidably provided on the vegetable box. Like this, a part of vegetable box 301 and fruit box 302 uses metal plate 6, utilizes the radiation effect of metal plate, not only has improved the effect that vegetable room is carried out radiation cooling, and can improve the temperature distribution in vegetable box and fruit box, can provide A box inside the vegetable chamber that stabilizes the temperature. The metal plate on the bottom surface is integrally formed with the plastic parts of the box, and can also be fixed by parts such as screws. In this case, since the metal plate is exposed indoors, the cold air in the room generated by the ra...

Abstract

A refrigerator which may allow vegetables kept more fresh by minimizing temperature fluctuations in a vegetable compartment. The refrigerator minimizes dehydration in food stored in the vegetable compartment, so that vegetables are kept fresh longer. The vegetable compartment is arranged so as to be surrounded by freezing temperatures, and cooled through radiation cooling without receiving blowing cool air thereto to minimize temperature fluctuations, so that vegetables may be keep more fresh. At the same time, the vegetable compartment is sealed so that convection does not occur thereby minimizing dehydration in food, so that food is allowed to be kept fresh longer. Furthermore, the refrigerator is provided with compartments whose temperatures may be set to freezing temperatures. The vegetable compartment is arranged so as to be surrounded by compartments whose temperatures are freezing temperatures via partition parts.

Description

technical field [0001] The present invention relates to a refrigerating refrigerator, which is provided with a storage room provided together with a refrigerating room and a freezing room, the storage room stores fresh food like a vegetable room, and when cooling vegetables and other organisms, the cold air is not directly supplied to the above-mentioned The radiation cooling method for cooling the vegetable chamber suppresses temperature fluctuations in the vegetable chamber. Background technique [0002] When the existing refrigerator is cooling the vegetable compartment, cold air is directly blown into the vegetable compartment for cooling. This will cause large temperature fluctuations in the vegetable chamber, and convection will occur in the vegetable chamber, which will dry the food in the vegetable chamber and shorten the preservation time of food freshness. For example, a refrigerator as shown in FIG. In this vegetable room 300, a vegetable box 301 and a fruit box...
