Technical Field

The invention relates to the technical field of preservation devices, in particular to a preservation box assembly capable of vacuumizing from the bottom and a refrigerator applying the preservation box assembly.

Background

In recent years, people's health consciousness is gradually improved, and the demand for food material preservation is also improved, so that the refrigerator is used as the most common household appliance for storing food materials, and the food material preservation storage becomes a technical demand to be solved urgently in the field of refrigerators.

At present, different preservation technologies are proposed by various manufacturers aiming at the problem of food material preservation and storage. For example, in the vacuum preservation technology, the food deterioration condition is changed in the vacuum state. Firstly, in a vacuum environment, microorganisms and various promoting enzymes are difficult to survive, and the requirement of microorganism breeding can be met for a long time; secondly, under the vacuum state, the oxygen in the container is greatly reduced, various chemical reactions can not be completed, food can not be oxidized, and the food can be preserved for a long time.

The vacuum preservation technology applied to the refrigerator at present mainly comprises the steps that a sealed drawer is arranged in the refrigerator, and the drawer is vacuumized through a small vacuum pump arranged outside the drawer, so that the drawer is kept in a negative pressure state, and the preservation of food materials in the drawer is realized. This preservation method has the following limitations: 1. because the vacuum pumping treatment is realized by a vacuum pump, the vacuum pump can occupy part of the storage space of the refrigerating chamber; 2. the drawer is required to be sealed in the fresh-keeping mode, otherwise, the vacuum state cannot be formed in the drawer, and therefore higher requirements are provided for the forming and assembling processes of the drawer; 3. the drawer belongs to an inherent part in the refrigerator, and the drawer can not be taken out of the refrigerator for random transportation, so that the drawer is inconvenient for the transportation and the use of vacuum fresh-keeping articles.

In order to solve a series of problems caused by vacuumizing and refreshing by using a drawer, the applicant previously applied a related patent that a refreshing box is arranged on the side of a door body inner container, a base is arranged on the side of the door body inner container, the refreshing box is placed on the base, a vacuumizing connector device is further arranged on the side of the door body inner container, and the vacuumizing connector device is communicated with a vacuumizing interface at the top of the refreshing box so as to vacuumize the refreshing box. During operation, after the preservation box is placed on the base, the vacuumizing connector device and the preservation box vacuumizing interface are required to be manually connected. When taking off the crisper from the base, still need manual taking off the vacuumizing joint device from the crisper earlier, just can take away the crisper.

[ fresh-keeping box component ]

Referring to fig. 4, 8, and 9, the crisper assembly 400 comprises an outer box 410 and a plurality of inner boxes 420.

An accommodating cavity 413 is formed in the outer box 410, a vacuum interface 411 is arranged on the outer box 410, and the vacuum interface 411 is connected with an external vacuum device.

Taking the preservation box assembly 400 as an example for application to a refrigerator, the vacuum interface 411 is used for connecting with the vacuum connector 500 on the refrigerator.

The inner cases 420 are placed in the accommodating chamber 413 of the outer case 410, and the inner cases 420 are provided with the air outlet sealing part 421.

When the accommodating chamber 413 is evacuated by the evacuation device, the inner chamber 422 of the inner box 420 is communicated with the accommodating chamber 413 through the air outlet sealing portion 421.

Along with the vacuum pumping, the gas in the inner cavity 422 flows into the accommodating cavity 413 through the air outlet sealing part 421 and flows out through the vacuum pumping interface part 411, and the pressure in the inner cavity 422 is gradually reduced until reaching the required low-pressure environment, so as to meet the low-pressure fresh-keeping storage requirements of different food materials.

After the containing cavity 413 is vacuumized, the air outlet sealing part 421 seals the inner cavity 413 of the inner box 420, so as to avoid pressure relief and maintain low pressure.

The crisper box assembly 400 is in a box structure form, and different inner boxes 420 can be used for storing different food materials, so that the food materials can be stored independently.

Through carrying out the evacuation to same outer box 410, can be to a plurality of interior boxes 420 evacuation simultaneously, realize the fresh-keeping storage demand of low pressure of the edible material of the independent storage of a plurality of partitions simultaneously, it is more convenient to use, efficient.

Otherwise, the vacuum pumping is performed to the preservation boxes (i.e. the inner boxes 420) each containing different food materials one by one.

In some embodiments of the present application, the vacuum interface 411 is disposed at the bottom of the outer casing 410, and the crisper assembly 400 is evacuated from the bottom.

Thus, the vacuumized pipeline 620 and the wires 650 for control are arranged in a partitioned mode, the pipeline 620 and the wires 650 are prevented from being staggered and disordered, the pipeline 620 and the wires 650 can be maintained conveniently in a partitioning pipe routing structural mode, and the internal structure is more regular.

When maintenance of the vacuum fitting 500 and the conduit 620 is required, the top plate 350 is removed from the top and maintenance is performed from the top 350.

When the switch 630, the wires 650, and the like need to be repaired, the outer bottom plate 360 is detached from the bottom, and the repair can be performed from the bottom.

The bottom cavity 310 and the trace maintenance cavity 320 are partitioned and distributed in an isolated manner from top to bottom to better realize respective functions.

In this embodiment, the switch 630 is disposed on the side plate 340 at the front side for the user to operate.

Referring to fig. 7 and 8, a mounting groove 331 is formed in the inner bottom plate 330 toward the routing maintenance cavity 320, and a control board 640 connected to the switch 630 is disposed in the mounting groove 331, so as to provide a mounting space for the switch 630 and the control board 640.

The wiring groove 332 is formed in the inner bottom plate 330 and faces the wiring maintenance cavity 320, the wiring groove 332 is communicated with the mounting groove 331, and wires 650 led out from the switch 630 and the control panel 640 are led out through the wiring groove 332 to avoid messy wires.

The mounting groove 331 further functions to support the top plate 350, that is, referring to fig. 8, the top plate 350 is simultaneously abutted against the supporting part 334 and the top surface of the mounting groove 331, further improving the reliability of the top plate 350.

In some embodiments of the present application, a plurality of supporting pillars 333 are integrally formed on the inner bottom plate 330, a plurality of openings 351 are correspondingly formed on the top plate 350, and the tops of the supporting pillars 333 are exposed from the openings 351.

Referring to fig. 8, the bottom of the crisper assembly 400 is provided with feet 430, and when the crisper assembly 400 is placed on the shelf 300, the feet 430 rest on the support posts 333. The support posts 333 support the crisper assembly 400, and the top plate 350 does not bear the weight of the crisper assembly 400, because the support posts 333 are integrally formed on the inner bottom plate 330, the support structure is more stable and reliable.

In some embodiments of the present application, referring to fig. 4 and 5, a plurality of vacuum joints 500 are disposed in the bottom chamber 310, and the corresponding vacuum joints 500 correspond to a plurality of vacuum interfaces 411 on the outer box.

Every evacuation connects 500 all to be provided with switch 630 independently, like this, can make through different evacuation connects 500 and reach different low pressures in the preservation box subassembly 400 to satisfy the fresh-keeping environment of the required different low pressures of different edible materials in the different preservation box subassemblies 400.
