Abstract
The utility model relates to manufacture of a household refrigerator. The utility model is formed by that the inner parts of doors of a refrigerated chamber and a refrigerating chamber are respectively provided with an electromagnet, the inner part of a door handle is provided with a single pole two-way instantaneous switch. The utility model changes the present situations that opening the door of an existing refrigerator is strenuous and inconvenient, and the magnetism of magnetic stripes is easy to reduce because of long term use. The utility model has the advantages of simple structural design, reasonable layouts, raw material saving and little space occupation.
Description
The utility model relates to the manufacturing of household electric refrigerator.
Existing refrigerator gasket mostly is magnetic stripe, seals by its magnetic force, reaches the purpose of insulation.But its magnetic of this magnetic stripe can very longly in time weaken, and very long the reducing of magnetic force meeting causes an envelope not tight, reduces refrigerator efficient.And the refrigerator doors that has envelope tension causes effort when opening, or overexerts and cause accident.
The utility model purpose provides a kind of refrigerator doors that makes things convenient for, and can overcome the shortcoming of prior art, utilizes the multinomial characteristic of electromagnet, changes then as electric current in the coil that the magnetic pole of magnet changes accordingly, and the homopolar-repulsion heteropole is inhaled mutually.The utility model is opened the tightness that strengthens the door envelope simultaneously again, and magnetic force is difficult for disappearing.
The utility model is that electromagnet is placed by edge in refrigerating chamber and refrigerating chamber door, and the corresponding permanent magnet of placing at the refrigeratory body place is provided with hilted broadsword two-way instant shut-in and constitutes in door handle.
The utility model is described in detail as follows with reference to Figure of description:
Fig. 1 is the utility model front view.
Fig. 2 is a circuit diagram.
As shown in the figure, place electromagnet 1 as magnetic dot (2-4) in refrigerating-chamber door, place electromagnet 2 in the refrigerating chamber door as magnetic dot (2-4), each magnetic dot connects power supply and forms the loop, in refrigeratory body, place permanent magnet 3 as corresponding magnetic dot (2-4), and in door handle 4, switch is set.Switch 5 is the hilted broadsword two-way, with the change sense of current, and is instant shut-in.Switch can have various ways, as: mechanical type, infrared ray tactile etc.Magnetic dot is when producing repulsion, and door can automatically spring open, but can not flick very big.And magnetic dot can produce the sealing that lasting gravitation helps door when closing.
The utility model changes the present situation inconvenient and that use magnetic stripe magnetic easily to weaken for a long time of requiring great effort when the current refrigerator door is opened.Utilize the principle of electromagnet corresponding change of magnetic pole meeting when the sense of current changes and the principle that the homopolar-repulsion heteropole is inhaled mutually, make to produce the convenient unlatching of repulsion when desiring to open the door, help sealing and produce gravitation at closing time.The utility model structural design is simplified, and is rationally distributed, saves raw material, and installing space is little, applied range.
Claims (2)
1. a refrigerator makes things convenient for door, it is characterized in that it is that edge places electromagnet respectively in refrigerating chamber and refrigerating chamber door, each electromagnet connects power supply and forms the loop, and places corresponding permanent magnet in refrigeratory body, hilted broadsword two-way instant shut-in is set in door handle constitutes.
2. according to the convenient door of the said refrigerator of claim 1, it is characterized in that said switch is mechanical type or infrared ray tactile.
