Description

Moisture-keeping refrigerator

Technical Field

The invention belongs to the technical field of refrigerators, and particularly relates to a moisture-preserving refrigerator.

Background

Along with the improvement of the living standard of people, the refrigerator has higher and higher requirements on the fresh-keeping performance. Particularly, when a user stores food materials with high moisture content such as fruits and vegetables, the refrigerator is required to provide a storage space with high humidity. Due to the characteristics of a refrigerating system, the single-system air-cooled refrigerator has long been in a state of low humidity of a refrigerating chamber, and fruits and vegetables are often subject to water loss and wilting after being stored for a long time. The existing market has few moisturizing technologies aiming at single-system air-cooled refrigerators, most of the existing moisturizing technologies are mechanical regulation and control moisturizing technologies aiming at small-space small drawers, and the moisturizing effect of the technologies is weak. In addition, the water is added from the outside for humidification, so that the moisturizing effect is obvious, but the convenience is poor for users. Therefore, a moisture retention technology capable of solving the problem of the refrigerating chamber of the single-system air-cooled refrigerator is urgently needed by consumers.

Disclosure of Invention

The invention aims to provide a moisturizing refrigerator to solve the problems in the background technology.

In order to solve the technical problems, the invention is realized by the following technical scheme:

the invention relates to a moisture-preserving refrigerator, which comprises a refrigerating chamber and a freezing chamber, wherein the freezing chamber is provided with an evaporator and a refrigerating fan; the refrigerating chamber is provided with a refrigerating air duct, an air outlet and an air return port; a pipeline communicated with the outside is also arranged in the refrigerating chamber; a micro fan and a water permeable module are arranged in the pipeline; the module of permeating water includes fixed bolster and the membrane material that permeates water.

Furthermore, one end of the pipeline is provided with an air inlet communicated with the outside, and the other end of the pipeline is provided with an air outlet communicated with the refrigerating chamber.

Further, the micro fan is connected with a refrigerator control system.

Further, at least one humidity sensor is arranged in the refrigerating chamber.

The invention has the following beneficial effects:

according to the invention, the pipeline communicated with the external environment is arranged in the refrigerating chamber, the micro fan provides power to introduce external water vapor into the pipeline, and when air flow reaches the water-permeable film material, water molecules selectively penetrate through the pipeline, so that a large number of water molecules enter the refrigerating chamber as far as possible, thus the average relative humidity of the refrigerating chamber is improved, the storage quality of fruits and vegetables is improved, and the fresh-keeping requirement of consumers is met; meanwhile, the permeable membrane material blocks or delays the entry of high-temperature gas in other external environments, so that the temperature of the refrigerating chamber is prevented from being greatly fluctuated, and the amplitude of energy consumption increase is reduced.

Of course, it is not necessary for any product in which the invention is practiced to achieve all of the above-described advantages at the same time.

All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

In the description of the present invention, it is to be understood that the terms "opening," "upper," "lower," "thickness," "top," "middle," "length," "inner," "peripheral," and the like are used in an orientation or positional relationship that is merely for convenience in describing and simplifying the description, and do not indicate or imply that the referenced component or element must have a particular orientation, be constructed and operated in a particular orientation, and thus should not be considered as limiting the present invention.

Referring to fig. 1-4, the invention relates to a moisture-keeping refrigerator, which comprises a refrigerating chamber 1 and a freezing chamber 2, wherein the freezing chamber 2 is provided with an evaporator 3 and a refrigerating fan 4; the refrigerating chamber 1 is provided with a refrigerating air duct 11, an air outlet 6 and an air return opening 7;

a pipeline 8 communicated with the outside is also arranged in the refrigerating chamber 1;

a micro fan 14 and a water permeable module are arranged in the pipeline 8; the water permeable module comprises a fixed bracket 16 and a water permeable membrane material 15; the permeable membrane material 15 covers the fixed support 16 to ensure that the air flow completely passes through the permeable membrane material 15.

Preferably, one end of the duct 8 is provided with an air inlet 9 communicated with the outside, and the other end of the duct 8 is provided with an air outlet 10 communicated with the refrigerating chamber 1; the air outlet 10 of the pipeline 8 is arranged at any position of the refrigerating box body, so that the interference with the original structure in the refrigerating chamber is avoided.

Preferably, at least one humidity sensor 13 is provided inside the refrigerating compartment 1.

Preferably, the micro fan 14 is connected to the refrigerator control system; when the micro-fan 14 is activated, the air flow is directed from the outside environment to the refrigerating compartment 1.

The micro fan 14 is turned on to satisfy any one of the following conditions:

1) the refrigerating chamber is used for refrigerating, when the refrigerating chamber 1 is not used for refrigerating, the micro fan 14 is started, and the working time of the micro fan 14 is 5-10 min;

2) when the compressor stops, the micro fan 14 is started until the compressor is started;

3) when the humidity sensor 13 detects that the humidity in the refrigerating chamber 1 is lower than a certain range, the micro fan 14 is started; wherein the humidity range is 15-35%.

The water permeable module can be arranged at any position in the pipeline; the permeable membrane material 15 is a selectively permeable material, water molecules can pass through, and other gases do not pass through or slowly pass through; the aperture range is 0.1 nm-1 nm.

As shown in the figures 1-2, the air inlets of the ducts are arranged at the back plate and the side wall box shell of the refrigerating chamber.

As shown in fig. 3-4, when the air inlet of the pipeline is arranged in the compressor bin, the air inlet of the pipeline is in a horn shape, and the water permeable module is arranged at the horn mouth, so that the contact area of the membrane material and air is increased as much as possible.

When the freezing chamber 2 is used for refrigerating and the refrigerating chamber 1 is not used for refrigerating, the refrigerating chamber 1 is weak negative pressure, outside air enters the pipeline 8 due to pressure difference, and after the micro fan 14 is started to work for 5-10 min, a large amount of water molecules are guaranteed to enter the refrigerating chamber through the water permeable film material 15, and the humidity in the refrigerating chamber is improved. When the compressor is stopped, the micro fan 14 is turned on to replenish the moisture removed by the cooling of the refrigerating compartment 1. When the humidity sensor 13 in the refrigerating compartment 1 detects that the humidity in the compartment is lower than 15% to 35%, indicating that the refrigerating compartment 1 requires dehumidification, the micro fan 14 is turned on to force a high-humidity airflow into the refrigerating compartment 1 to replenish humidity.
