Embodiment 1

[0024] Example 1, such as figure 1 , figure 2 As shown, a fresh-keeping cabinet includes a cabinet body 1 and a side door 2 hinged on the cabinet body 1 . Ventilation holes are arranged on the outer surface of the fresh-keeping cabinet, and the ventilation structure of the ventilation holes can also be replaced by a louver ventilation structure 4 . A capillary material layer 3 extends from the bottom surface of the fresh-keeping cabinet to the top surface and is arranged on the side wall of the storage space of the fresh-keeping cabinet. The capillary material layer is mainly considered from the structure, and is not limited to one material, as long as the sum of the void surface area of ​​the capillary material layer is greater than the surface area of ​​the capillary material layer, the porosity of the capillary material layer is between 20% and 50%; at the same time, it has good A hydrophilic capillary material is sufficient. The capillary material layer can be made of ...

Embodiment 2

[0034] Embodiment 2, the capillary material layer is made of hemp bark that is ground into granules, or reed that is ground into granules, or wheat straw that is ground into granules, or bark that is ground into granules, or ground into granules. The combination of burlap bark and reed in granular form, or the composition of bark husk, reed, bark and wheat straw crushed into granular form is produced by pressing. The porosity of the capillary material layer is 20% to 50%. Refer to Embodiment 1 for the rest of the structure in this embodiment.

[0035] The material of the capillary material layer in Example 2 is natural fiber, which has better hydrophilicity than artificial fiber. Importantly, the capillary material in this scheme is crushed into granules, the capillaries in the material fibers are cut and arranged in a disordered manner. Since the capillary in the capillary material fiber is cut off, water can be better absorbed in the capillary material layer without flowin...

Embodiment 3

[0036] Example 3, such as Figure 5 As shown, the capillary material layer 3 is composed of an inner capillary material layer 32 and an outer capillary material layer 31 . The porosity of the inner capillary material layer 32 is 20% to 30%; the porosity of the outer capillary material layer 31 is 50% to 80%. The inner capillary material layer is in contact with the storage space of the fresh-keeping cabinet, and the outer capillary material layer is in contact with the external space; the thickness of the inner capillary material layer is smaller than that of the outer capillary material layer.

[0037] The specific structure is: the fabric bag 13 provided in the nesting 21 in embodiment 1 is provided with a fabric interlayer 23 to separate the fabric bag 13 into two layers inside and outside; the capillary material is filled in the inside and outside layers of the fabric bag respectively space, and apply different pressures to the capillary materials in the inner and outer s...

Abstract

The invention discloses a preservation cabinet, and aims to provide a non-power-consumption preservation cabinet which has the advantages that external heat can be effectively obstructed, the water evaporation efficiency is increased, more heat is brought away and the humidity in the cabinet is increased so as to improve the preservation effect. The preservation cabinet comprises ventilation holes or louver ventilation structures, a capillary material layer, a trough and a waterway passage, wherein the ventilation holes or the louver ventilation structures are formed in side faces of the preservation cabinet; the capillary material layer is arranged on the side wall of a storage space of the preservation cabinet in the way of extending from the bottom surface of the preservation cabinet to the top surface; the trough is formed in the bottom surface of the storage space of the preservation cabinet in the way of extending along the edge of the bottom surface of the storage space of the preservation cabinet; the bottom of the capillary material layer extends into the trough; the waterway passage is arranged in a top cover of the preservation cabinet in the way of extending along the edge of the top surface of the storage space of the preservation cabinet; and the lower part of the waterway passage is provided with a plurality of fine meshes for communicating the capillary material layer with the waterway passage.

Description

technical field [0001] The invention relates to a fresh-keeping device, in particular to a fresh-keeping cabinet without power consumption. Background technique [0002] With the improvement of living standards, food preservation has been widely used in daily life, such as common plastic wrap, fresh-keeping bags and refrigerator fresh-keeping. The fresh-keeping effect of plastic wrap and fresh-keeping bag is not good; although the refrigerator has a good fresh-keeping effect, it consumes a lot of power. In order to solve these problems, some inventors use the principle of water evaporation to absorb heat and increase the air humidity through water evaporation to improve the preservation effect. For example, Chinese Patent Publication No. CN2049893, the publication date was December 27, 1989. The name of the invention is a fresh-keeping counter for fruits and vegetables. The fresh-keeping counter for fruits and vegetables is formed by racks, and the display and sale fruit a...
