Problems solved by technology

However, although this B-type silica gel is effective in a room with a lot of moisture such as a refrigerator room and a vegetable room, it cannot obtain the same effect in a freezer room whose room temperature is set at -18°C or lower.
Therefore, it cannot be transferred to the freezer
In other words, since B-type silica gel has the characteristics of poor moisture absorption in places with low relative humidity and high moisture absorption in places with high relative humidity (refrigerator or freezer), it cannot be transferred to freezers with low relative humidity.

Embodiment Construction

[0028] Embodiments of the humidity-maintaining freezing refrigerator in the freezing chamber of the present invention will be described below with reference to the drawings.

[0029] First, use Figure 1 ~ Figure 4 The freezing refrigerator of the present embodiment will be described. figure 1 It is a front view which omits the door of the freezing refrigerator of this Example. figure 2 yes figure 1 H-H line sectional view. image 3 It is a perspective view of the partition parts collection. Figure 4 It is a perspective view showing the back side of the separator parts collection product.

[0030] The freezer refrigerator 1 has a refrigerator compartment 2, a freezer compartment 3, and a vegetable compartment 4 from top to bottom. Furthermore, although not shown, a door is provided over the entire opening of the chamber. In particular, the door which closes the whole opening part of the freezer compartment 3 and the vegetable compartment 4 is formed in the pull-out t...

Abstract

The invention provides a refrigerator-freezer capable of suppressing discharge of moisture of food through plastic food wrap in a freezing chamber reaching a temperature of -18 DEG C or lower. In the refrigerator carrying out forced circulation of cold air cooled by a cooler (9) to the freezing chamber (3) by using a blowing means such as a cold air circulation fan (10), an absorbing and releasing material (13) having moisture absorbing power even in a place with low relative humidity is provided in the freezing chamber (3).

Description

technical field [0001] The present invention relates to a freezing refrigerator. Background technique [0002] In the freezer compartment (room temperature 3.0-5.0°C) and vegetable compartment (room temperature 3.0-6.0°C) of commercially available refrigerators, for the purpose of absorbing humidity from the contents to prevent the deterioration of the appearance and taste of the contents, it is used in each The chamber is equipped with a moisture absorbing and desorbing member that absorbs moisture when the chamber is high in humidity and releases moisture stored in the high humidity when the chamber is low in humidity (for example, refer to Patent Document 1 - JP-A-2001-91145). [0003] Existing freezers do not conceive of maintaining a high humidity in the freezer chamber containing meat, fish, etc. at all. [0004] That is, food such as meat and fish stored in the freezer must be wrapped with a commercial plastic wrap (polyvinyl chloride plastic wrap) when purchased in ...
