Abstract

The utility model discloses a magnetic fresh preservation box which belongs to a household appliance for daily use and can be used for the preservation of fruits, vegetables and foods. The utility model is mainly characterized in that a top board, middle partition boards and a bottom board of the magnetic fresh preservation box adopt magnetic boards; each of the inner parts of the magnetic board is provided with a plurality of permanent magnets which are in parallel arranged at intervals and is formed by fixing upper and lower clamping boards; the upper and the lower clamping boards are made of thin iron plates, plastic boards, etc. which are easy to magnetize; the top board and the bottom board which can provide magnetic fields for the magnetic fresh preservation box are used as constituting components and strengthen the body of the magnetic fresh preservation box; the middle partition boards by which the magnetic fresh preservation box is divided into a plurality of preservation rooms can also provide magnetic fields. The utility model has the advantages of simple structure, low manufacture cost, no energy consumption and good preservation effect.

Description

Magnetic fresh preservation box

The utility model belongs to the family life apparatus, is used to preserve the freshness preserving equipment of fruit, vegetables and food.

Fruit, vegetables and food fresh keeping have several different methods, as bury, mound storage, refrigeration, chemical treatment storage, also can utilize fruit and vegetable to have the air discharge fresh equipment etc. of biological electricity characteristics principle design.Though preservation method is many, be fit to the general employing refrigeration that family uses, refrigerator is common family's freshness preserving equipment., use and want consumed power, have ready conditions in China at present and use the just minority family of refrigerator because refrigerator costs an arm and a leg.

The CN86204896U of Patent Office of the People's Republic of China discloses a kind of vegetable food antistaling box, this antistaling box divides main body case and storage box, leave interlayer between two the casees, chest designs respectively up and down the running water import and export, when the tap water flows interlayer, the temperature of running water (general about 10 ℃) plays constant storage box temperature action, thereby reaches the preservation by low temperature purpose.Though this antistaling box is relatively simple for structure, but the major defect in the design is: in summer, the running water temperature can reach about 10 ℃ only in the northern China city, just possible with the running water that extracts groundwater resources in the deep-well simultaneously, at south and the running water that utilizes river, river, lake water to produce, water temperature does not reach this low temperature, so the sectional center that this antistaling box uses is sex-limited very big; Even moreover in the north, the rural area of vast no running water also can't be used.

The purpose of this utility model is to provide a kind of structure more simple, with low cost, does not need consumes energy, is not subjected to a kind of new fruit, vegetables and the food fresh keeping equipment of area and environmental condition restriction.

Experiment repeatedly according to the utility model designer, when the magnetic field that fresh fruit of vegetables or food is placed certain intensity, the physiological metabolism effect of plant cell greatly reduces, and the food spoilage microbial activities is suppressed, and magnetic field energy plays preservation to fruits and vegetables, the food that stores.In view of the above, as long as we be designed to have magnetic with common storage box, so just can become antistaling box.The utility model simplicity of design, just whole the or local casing with storage box adopts magnetic sheet to make.Employed magnetic sheet is made with permanent magnets, method be with a certain size permanent magnets at certain intervals, be arranged in parallel between the sheet iron or plastic plate of two easy magnetizations, fixed with filler around the permanent magnets, then again two sheet irons or plastic plate are got final product with fastener is fastening.The function of magnetic sheet is for antistaling box provides magnetic field, is again simultaneously that the component part of casing plays static housing and the fresh-keeping thing of carrying.The utility model adopts metal or timber structure, except the top board of antistaling box, base plate, median septum with the magnetic sheet, the backboard of case, side plate even chamber door available metal plate, plank also can be made of window screening, help circulation of air.

The utility model is simple in structure, and production cost is low, does not need consumes energy, and city, rural area can both be used.The utility model is better to the fresh-keeping effect of fruits and vegetables and food, and when 28 ℃-30 ℃ of room temperatures, the flesh of fish based food freshness date of decoction is two to three days; Remaining food freshness date one to two day; To the perishable food fresh keeping phases such as Raw bean curd be one day.Also comparatively desirable to fruit, Vegetable Preservation, appearance luster changes little, and moisture content scatters and disappears few.

Now in conjunction with the accompanying drawings the utility model embodiment is described in detail.Figure one is magnetic antistaling box integral body and fragmentary, perspective view; Figure two is the magnetic sheet sectional elevation.Magnetic antistaling box shown in figure one, its top board (1), median septum (2-1), (2-2) and base plate (3) all adopt magnetic sheet.Top board (1), base plate (3) are the component parts of casing, and except that playing the reinforcing casing, its major function provides magnetic field, and base plate (3) is the loading plate of fresh-keeping thing still.Median septum (2-1), (2-2) also are the loading plates of fresh-keeping thing both for antistaling box provides magnetic field, and antistaling box is divided into several fresh-keeping chambers.Top board (1), median septum (2-1), (2-2), between the base plate (3) at a distance of 8-14 centimetre.Median septum (2-1), (2-2) can be fixed on the side plate (4) on casing both sides, also can be on biside plate pumping slot, median septum is freely inserted, help the user like this and adjust the fresh-keeping chamber volume as required.Magnetic antistaling box shown in the figure one also has chamber door (5), chamber door handle (6), case pin (7), component parts such as side plate (4) and backboard.Chamber door (5), side plate (4), backboard etc. can adopt metal, wooden, plastic plate etc., also can inlay with window screening.The magnetic sheet structure is shown in figure two, and magnetic sheet has permanent magnets (8), last lower plate (9), (10), filler formations such as (11).Generally long 4 centimetres of permanent magnets (8), wide 2.5 centimetres, thick 0.3～0.4 centimetre long cube, it is arranged in parallel in last lower plate at certain intervals, between the permanent magnets (8) apart 2.5～3 centimetres.The sheet iron or the plastic plate of easy magnetization adopted in the last lower plate (9) of magnetic sheet, (10), fixes with fastener between last lower plate (9), (10).Filler (11) only plays fixedly permanent magnets, can make of materials such as foamed plastics.Can make strip and block, can be overall structure also, embeds permanent magnets on the relevant position.
