Abstract

The utility model relates to a vacuum fresh keeping storing box. Outlets of an air pumping tube connected with an integral vacuum pump formed by a vacuum pump chamber of the utility model and a set of storing chamber are respectively communicated with each storing chamber. The storing chambers are pumped to be a vacuum under the control of a vacuum inducting switch. An air inlet valve is opened when the storage chamber is opened, and the inner part of the box is pumped to be a vacuum again after food is taken out and a door is closed so that the goal of food fresh keeping is achieved. The utility model has the advantage of simple structure, electricity saving and no pollution. The utility model can replace the refrigerator and the refrigerating cabinet at present for the fresh keeping of food.

Description

The vacuum freshness retaining hutch

The utility model relates to a kind of food fresh keeping storage equipment, belongs to household appliance technical field.

Family food fresh keeping storage generally all adopts refrigerator ice cabinet, but refrigerator or refrigerator-freezer exist power consumption height, contaminated environment, cost an arm and a leg, noise is big, the working time is long, destructible food nutrition, the easy taint of odour of food, defective such as easy care not.

The purpose of this utility model is: utilization vacuum freshness retaining principle designs a kind of vacuum fresh-keeping box, and this antistaling box economizes on electricity, valency is low, pollution-free, do not destroy food nutrition, easy care, has overcome the defective of current refrigerator preferably.

The purpose of this utility model is achieved in that vacuum fresh-keeping box is formed by connecting by vacuum pump chamber and one group of vacuum storage compartment, the mouth of pipe of bleeding communicates with each storeroom, there are filter screen and one-way cock in the mouth of pipe place of bleeding, connect the running of vacuum pressure inductive switch control vavuum pump in the exhaust pipe, after chamber door is closed because vavuum pump work, one-way valve opens is extracted gas in the case out, makes food fresh-keeping in a vacuum.During pulling chamber door handle, the handle stage clip presses off the air inlet valve on the storeroom door, extraneous air is in chamber door enters case, and chamber door can easily be opened, and is taking out food, after closing chamber door, owing in the pipeline air is arranged, the vacuum pressure inductive switch starts, and vavuum pump is task again, extraction enters the gas in the case, makes to continue to keep vacuum in the case.

Fig. 1 is a structural representation of the present utility model

Further introduce implementation method of the present utility model below in conjunction with accompanying drawing: antistaling box is made up of storeroom 1,13 and lower floor's vacuum pump chamber 10, the city is electrically connected power switch 8 backs and connects vacuum pressure inductive switch 11 and motor 9, motor 9 links to each other with vavuum pump 12, exhaust tube 7 is connected on the vavuum pump 12, exhaust tube 7 has opening 14,15 respectively in storeroom 1,13, exhaust tube opening 15 place's check valves 17, exhaust tube opening part 14 has check valve 18, handle 4 is arranged on the preservation and freshness chamber door 5, handle 4 links to each other with spring leaf 2, intake valve 3 with shake hands 4 to link to each other.Intake valve 3 is adjacent to chamber door under the effect of spring leaf 2, open when pulling handle 4 intake valves 3, and air is gone in the storeroom 1 by intake valve 3, and chamber door 5 is opened.Air enters exhaust tube 7 by check valve 17, makes check valve 18 be adjacent to the mouth of pipe, closes chamber door 5, owing in the pipeline 7 air vacuum pressure inductive switch 11 starter motors 9 are arranged, the air in the storeroom 1 is extracted in vavuum pump 12 work.When the vacuum of storeroom 1 and 13 all reaches when vacuum is set, vacuum pressure inductive switch 11 cuts off motors 9 power supplys, and vavuum pump 12 quits work.The door of opening vacuum storage compartment 13 with open vacuum storage compartment 1 in like manner.

The utlity model has following advantage and effect: simple in structure, easy to use, joint The electricity successful, pollution-free, performance and price is better than refrigerator, can be widely used in family, School, hospital etc.
