Abstract
The utility model relates to a domestic vacuum box, mainly comprising a vacuum system and three vacuum chambers, which are all tightly disposed in a box. With an appearance like a multi-door refrigerator, the utility model can be used for refreshment and storage and for vacuum packing with plastic bags in the box to small quantity of articles in household. Matched with special fittings, the domestic vacuum box can carry out vacuum soft or hard packaging for articles out of the box. The idle vacuum degree of the utility model can reach 10+[-2]mm pump columns, with very good preserving effect and with the weight of about 31 kg. The utility model has the advantages of low cost (about 400 RMB) and low power consumption.
Description
The utility model belongs to a kind of vacuum technique that adopts, and is used for the device of family's fresh-keeping and storing and Vacuum Package.
Electric refrigerator is widely used in family and stores food and make frozen food, but to deliquescent crisp food such as fried food, fry in shallow oil the stir-fry dry fruit, sugar, part cake etc. can not play the effect that keeps crisp and former proterties, more can not be to the food and the article of deliquescence dry, recover former proterties, and electric refrigerator cost height, power consumption is big, it is many that most families are used to store food, it is few to be used for ice making, wish to have more cheap and good-quality, the food storage device of little power consumption comes out, in recent years, some research and design aspect the storage of family expenses vacuum freshness retaining, link to each other by coupler with multistage scroll casing type centrifuge blade pump as its motor of Chinese patent 87208225 (domestic food vacuum freshness retaining receiver), but the valve of up-and-down movement is connected with vacuum pump by pipeline and constitutes vacuum system, can move away from support after matching used with it vacuum tank is found time and place in addition, this device has certain vacuum freshness retaining effect to the food of depositing.But have following shortcoming: 1. final vacuum low (only being the 1760mm water column) is poor to the germ killing effect, and fresh-keeping effect is also poor.2. vacuum system does not have vacuum indicator.3. from general design, vacuum system and vacuum vessel are divided into two parts, not only use inconvenience but also are difficult to reach the purpose of beautifying indoor environment.4. during extracting vacuum, need pin aspirate tube till reaching required degree of vacuum with hand always.5. purposes is single.
The purpose of this utility model is in order to design a kind of family expenses vacuum tank, from general design, with vacuum system and vacuum tank close arrangement in a case, the case shell can be imitated the form of multi-door refrigerator, not only practicality but also attractive in appearance, cost is low, can contend for markets with electric refrigerator and like product.During work, only need energized, open valve switch, will bleed automatically, degree of vacuum can reach the 10-2mm mercury column, reaches the crisp effect of good fresh-keeping guarantor.
Another purpose of the present utility model be make this device can not only store, fresh-keeping, and can carry out the plastic bag vacuum sealed package of article, special vacuum packaging bag of adapted and special vacuum vessel bottle can also carry out the outer vacuum soft hard packaging of case.
Storage in vacuum of the present utility model is achieved like this, and the utility model mainly is made up of (referring to Fig. 1, Fig. 2) three vacuum chambers that work alone and a cover vacuum system.Vacuum system is mainly by motor, vacuum pump and each valve are formed, vacuum pump adopts the oil seal type oil-sealed rotary pump, pump has town's air valve, when preventing pump drainage steam, steam is compressed and condenses oil is degenerated, pump inlet is furnished with vacuum solenoid, prevent to return oil and oily vapour contamination vacuum chamber, behind electromagnetic valve, be connected vacuum indicator with vacuum lamp and an emptying finds time to control dual-purpose valve and three control cock, behind dual-purpose valve, connect the pin of bleeding and operate the usefulness of control so that vacuum-packed the bleeding of soft or hard to be provided case outside with the vacuum rubber pipe.Three control cock are connected to three vacuum chambers to control the pump drainage gas of three vacuum chambers respectively with vacuum rubber pipe and vacuum lamp respectively.Three vacuum chambers adopt non-toxic engineering plastic to be processed into integral body through plastic compression, have dovetail groove on the vacuum chamber flange, and embedded " O " type vaccum seal ring compresses the fully open type door voluntarily by bar pressure and realizes sealing.After degree of vacuum reaches the 10-2mm mercury column, reduced to through six days-550--700mm mercury column vacuum tank shell is formed by connecting by the thin plate rivet welding or the screw of polylith through forming work surface anti-rust treatment.In order to support vacuum system and vacuum chamber.Source switch is installed, four by-pass valve control levers and chamber door handle etc., shell landscaping treatment in addition on shell.In the time of need vacuumizing, only need close chamber door, energized, the empty pump of the vacuum that starts are opened three or corresponding vacuum control valve and just can be found time at the same time or separately to three vacuum chambers, observe the vacuum number of degrees from vacuum indicator, reach required degree of vacuum after.Close the vacuum control valve, cutting off the electricity supply gets final product.
Plastic bag vacuum sealed package of the present utility model is that this material is realized, the utility model vacuum chamber in the above is provided with a plastic bag vacuum sealed package device (referring to Fig. 3).This device adopts from metal bar of upper box part insertion and makes hook stick, rod and casing are by two " O " RunddichtringOs, suitably compress by means of two pads and with gland and to carry out vacuum seal, and rod can be slided up and down, the rod lower end connects a cross bar with the opening pin, the cross bar cross section becomes to remove the back taper of acute angle, the thicker rubber plate in shop at the bottom of the case under the cross bar, cross bar one end stretches into the groove on the casing, makes its location.During work, pad upper shed pad disengages cross bar and rubber sheet between hook stick and gland, plastics sack to be packaged is shakeout be placed between cross bar and the rubber sheet, close this door for vacuum chamber, primer pump is bled, and when reaching required degree of vacuum, takes off the opening pad, with hook stick under the hand, cross bar compresses the plastics sack, and the plastic bag of vacuum sealed package is taken out in broken then empty venting.Repeat previous action, can proceed the plastic bag Vacuum Package.
The utility model carries out the vacuum soft hard packaging outward to case and is achieved like this.The utility model is by connecting the pin of bleeding behind the vacuum system dual-purpose valve, use the special-purpose vacuum packaging bag special clip or the special-purpose vacuum vessel bottle that cooperate with it, the pin of will bleeding inserts vacuum packaging bag and clamps or insert in the special vacuum vessel bottle with special clip, close three by-pass valve controls of vacuum chamber, start vacuum pump and open dual-purpose valve, just can extract the air in this special use vacuum packaging bag or the special-purpose vacuum vessel bottle out, realize sealing.
The utility model is pressed the design drawing budget, and every cost is lower than 400 yuan, and a month power consumption is lower than 5 degree.
Compare with existing domestic food fresh-keeping and storing device, the utlity model has following advantage:
1. degree of vacuum height, unloaded degree of vacuum can reach the 10-2mm mercury column, and the crisp effect of fresh-keeping guarantor is fine.
2. vacuum system is furnished with vacuum solenoid and town's air valve, can prevent that pump from returning oil, keeps the vacuum chamber sanitation and hygiene, can prevent that also steam from condensing in oil.
General design with vacuum chamber and vacuum system close arrangement in a case, outward appearance such as electric refrigerator, both beautiful and practical.
4. serve many purposes, not only can fresh-keeping and storing.Can also be in case, carry out Vacuum Package outside the case.
5. cost is low, little power consumption.
