Abstract

The utility model discloses a vacuum fresh-keeping refrigerator, including a cooling room, a refrigerating chamber and a compressor, the utility model is characterized in that the vacuum pump is positioned at the internal side of the lower part of the refrigerator, the air inhale pipe of the vacuum pump is connected with the refrigerating chamber and cooling room, the exhaust pipe is connected with the air. The utility model adopts the structure and discharge the humidity out of the refrigerator to strengthen the vacuum degree inside the refrigerating chamber and cooling chamber, thus effectively reduce the oxygen and water needed by the epiphyte and bacteria for reproduction effectively curb the bacteria and prolong the shelf date of the food for purpose of fresh-keeping. At the same time, the model can adequately increase the temperature inside the cooling room, thus reducing the damage on the food and protecting the nutrition of the food.

Description

The vacuum freshness retaining refrigerator

One, technical field

The utility model relates to a kind of refrigerator, relates in particular to a kind of refrigerator with vacuum freshness retaining function.

Two, background technology

At present, all refrigerators all are to come fresh-keeping foodstuff by reducing temperature on the market.Some fungi and bacterium still have the possibility of breeding in lower temperature environments.Especially the refrigerating chamber of refrigerator is because temperature drift, and it is bigger to add humidity, helps the breeding of fungi and bacterium more, and it is rotten to make that food takes place easily, can't be fresh-keeping for a long time; Though and refrigerating chamber adopts freezing method that food is preserved, can partly contain the breeding of fungi and bacterium, but often need the temperature that reaches lower, can damage the eucaryotic cell structure of the animal and plant food that is saved like this, make its nutrition be subjected to very big destruction.

Three, summary of the invention

The purpose of this utility model is that design a kind ofly can be contained bacterial reproduction, the vacuum freshness retaining refrigerator that fresh keeping time is long, effective.

For achieving the above object, the technical scheme that the utility model is taked is: it comprises refrigerating chamber, refrigerating chamber and compressor, be characterized in: the inboard at lower part box is equipped with vavuum pump, and the exhaust tube of this vavuum pump communicates with refrigerating chamber and refrigerating chamber, and has blast pipe to communicate with atmosphere.

The utility model adopts said structure, just the part humid air in refrigerating chamber and the refrigerating chamber can be discharged outside the case, thereby increase refrigerating chamber and the interior vacuum of refrigerating chamber.Essential oxygen and moisture in the time of so just reducing fungi and bacterial reproduction effectively, thereby contain the breeding of mushroom effectively, prolonged the freshness date of food, reach the purpose of long-period freshness preserving.Simultaneously, can suitably improve the temperature in the refrigerating chamber, thereby reduce infringement, its nutrition is effectively protected frozen food.

The structural representation that Fig. 1 adopts compressor and vavuum pump to install respectively for the utility model;

The structural representation that Fig. 2 adopts compressor and vavuum pump disjunctor to install for the utility model;

Fig. 3 is compressor and a vavuum pump disjunctor scheme of installation among Fig. 2.

Five, the specific embodiment

The utility model can adopt following dual mode to implement:

Embodiment one: the mode that adopts compressor and vavuum pump to install respectively as shown in Figure 1, comprises refrigerating chamber 7, refrigerating chamber 4 and compressor 1; Next door at lower part box 8 inboard compression machines 1 is equipped with vavuum pump 2, and it communicates with refrigerating chamber 7 and refrigerating chamber 4 respectively by the

exhaust tube

6,5 that connects.Vavuum pump 2 tops are provided with the blast pipe 3 that communicates with atmosphere, are used for the gas of extracting out in refrigerating chamber 7 and refrigerating chamber 4 is discharged.

Embodiment two: the mode that adopts compressor and vavuum pump disjunctor to install.As shown in Figure 2, comprise refrigerating chamber 7, refrigerating chamber 4 and compressor 1; In lower part box 8 installed inside vavuum pump 2 with compressor 1 disjunctor is arranged.Vavuum pump 2 communicates with refrigerating chamber 7 and refrigerating chamber 4 respectively by the

exhaust tube

6,5 that connects.Vavuum pump 2 tops are provided with the blast pipe 3 that communicates with atmosphere, are used for the gas of extracting out in refrigerating chamber 7 and refrigerating chamber 4 is discharged; Vavuum pump 2 and compressor 1 conjoined structure are as shown in Figure 3, cylinder body 11 in vavuum pump 2 housings and the blade 12 in the cylinder body, bolt 16 by housing and binding housing and compressor is fixed on compressor 1 top, blade 12 in its cylinder body 11 is fixedly set in the rotating shaft 14 of compressor 1 built-in motor rotor 15, and rotates thereupon.Like this, in compressor 1 work, the blade 12 that just drives vavuum pump 2 rotates, thereby makes vavuum pump 2 work of bleeding.Do not need again to have saved the energy for vavuum pump 2 provides extra power supply.Among the figure 10,13 is respectively the exhaust outlet and the bleeding point of vavuum pump 2, externally connected exhaust pipe 3 and

exhaust tube

5,6.

Speed is housed on refrigerating-chamber door of the present utility model and refrigerating chamber door opens air valve 9.In the time that refrigerator doors need being opened, can open breather valve 9 earlier, to realize the case internal and external pressure balance with in the rapid leading-in box of case outer air.
