Vacuum preservation box structure improvement

This creation is about the improvement of the structure of a vacuum crisper, especially one that can draw the air in the crisper to a vacuum sealed state, so that the food in the crisper can be kept fresh.

Press, when the average person saves food, most of them use the original outer packaging directly. For example, the plastic bag and the lunch box are directly placed in the refrigerator for refrigerating or cryopreservation. However, the size and the amount of the food affect the volume of the outer packaging, such as direct use. Putting plastic bags and lunch boxes into the refrigerator will make the interior of the refrigerator messy, unable to use the space effectively, and it is not easy to stack. If the outer packaging is not flat, it may cause the food to overturn and fall after stacking, which leads to food and soup. Spilling out, not only causes waste, but also causes the environment to be messy. If the food is filled with the internal space of the refrigerator, the cold air inside the refrigerator will not circulate smoothly, which will reduce the effect of refrigeration, which may lead to food deterioration and increase the compression of the refrigerator. The operation of the machine not only costs electricity, but also reduces the life of the refrigerator. If the outer packaging is not sealed, the smell of the food will leak through the gap, causing the interior of the refrigerator to be filled with various odors, and even some will not be cooked. The ingredients are stained with these odors, causing inconvenience to the user.

Therefore, a related manufacturer has developed a vacuum crisper for research and improvement of the defect, and the conventional vacuum crisper includes a case, a cover detachably mounted on the case, and a case provided on the case Air valve, to use the inside of the vacuum crisper to reach a vacuum state, the user can The gas in the box is discharged by pressing the box with both hands, but this method often has a problem of poor pressing vacuum, so the user can also use a suction rod to align the valve, above and below. The piston rod of the air suction rod is reciprocally pulled or the air pumping operation is performed by means of electric driving, and when the piston rod is difficult to be pulled, the vacuum storage box reaches the vacuum state.

However, as described above, although the pumping rod can improve the pumping effect by the method of pressing with both hands, it has the following problems:

1. If the suction rod is manually operated, it is laborious, and it is easy to affect the vacuum degree of the vacuum storage box due to human operation factors, resulting in poor preservation performance.

2. If the pumping rod is electrically driven, it is necessary to consider the situation that the battery is out of power, which often causes inconvenience in use.

3. The vacuum storage box may be stored separately from the air suction rod, which may cause loss of inconvenience when the air suction rod is used and stored.

After the gas pressure is equal, the lid 2 can be easily opened to eat the food in the box 1 (as shown in FIG. 12); by the above, the purpose of the fresh-keeping box of the present invention is as follows: It is used in conjunction with the new patent of the "Machine Vacuum Refrigerator" of the Announcement No. M488613, and the air duct 24 provided in the lid 2 of the fresh-keeping box of the present invention is pumped through the air extracting member of the refrigerator. Action, the air guiding tube 24 provided by the lid 2 of the crisper is in a parallel state, and is convenient for aligning with a vacuum pumping refrigerator, and the air guiding tube 24 is used as the casing 1 When the air in the casing 1 is taken out by the air duct 24 of the cover 2, when the vacuum is to be evacuated, the extraction can be stopped, and the outside air does not flow into the casing 1. When the vacuum sealing state is reached, the air in the crisper can be evacuated to a vacuum sealed state; the vacuum box is placed in the refrigerator to be in a vacuum state, so that the food contained in the crisper box can be kept fresh; Consumers want to vacuum the crisper When taking the time, there is no need to bring in a suction rod or an air pump, so there is no fear of losing the pumping rod or the pumping cylinder, and there is no need to worry about the situation that the electric drive type suction rod or the air pump has no battery. In addition, the air box 24 is provided in the box cover 2 of the fresh-keeping box, and the air guiding tube 24 is in a parallel setting state, and only the air guiding tube 24 of the box cover 2 of the crisper box is required to be abutted against the device. The air suction member 42 provided in the vacuum pumping refrigerator can prevent the food contained in the box 1 of the creation crisper box from being flipped during the process of pumping; further, the refrigerator is pumped for the creation. The gas use process and the traditional manual pumping rod use process are compared as follows: This creation is combined with the process of using the refrigerator to pump: Step 1 (take the crisper) → Step 2 (cover the lid after loading the food) → Step 3 (to the refrigerator door for electric pumping) → Step 4 (Open the refrigerator door) → Step 5 (placed in the refrigerator) → Step 6 (close the refrigerator door); traditional manual pumping rod use process: Step 1 (take the suction rod) → Step 2 (take the crisper) → Step 3 (load the food Cover on the back cover) → Step 4 (Manual suction rod pumping) → Step 5 (Open the refrigerator door) → Step 6 (Place in the refrigerator) → Step 7 (Close the refrigerator door) → Step 8 (Pump the air) The rod is stored in the original place); it can be seen that the creation of the refrigerator with the refrigerator only requires 6 steps and the process is smooth, making the vacuum preservation process extremely convenient; in contrast, the traditional manual pumping rod must be used. The vacuum storage is completed in 8 steps, but there is still a premise that the user is familiar with the suction rod storage position, otherwise it is necessary to find the suction rod.

In summary, the improvement of the structure of a vacuum crisper has not been seen in the publications or public use. It is in line with the requirements of the new patent application, and it is requested to give a patent at the early date. To be clear, the above is the specific embodiment of the creation and the technical principles applied. If the changes made according to the concept of this creation, the functional role produced by it does not exceed the spirit of the manual and the drawings. At the time, it should be combined with Chen Ming within the scope of this creation.
