Abstract
The invention discloses a kind of electromagnetic door seal, it is characterized in that: comprise gum cover, rubber magnetic stripe, spiral winding, the first toroidal conductor and the second toroidal conductor; Wherein, load rubber magnet bar in gum cover, imbed the first toroidal conductor in rubber magnetic stripe, the periphery of rubber magnetic stripe is wound with spiral winding; Corresponding with the position of first ring wire on the mouth frame that second toroidal conductor is arranged on casing.The present invention utilizes electromagnetic attraction to ensure the sealing of refrigerator door and casing, also can easily open the door simultaneously.
Description
Technical field
The present invention relates to seal strip for refrigerator door.
Background technology
Seal strip for refrigerator door is used in the refrigerator part being used between refrigerator door and casing sealing.In order to prevent cold air and extraneous hot gas exchange heat in refrigerator, posting magnetic stripe in Men Tiyu casing junction, i.e. magnetic door seal, relying on the magnetic force of magnetic stripe, together with tightly being inhaled with casing by refrigerator door.Gasket is made up of gum cover and magnetic stripe, and the main component of gum cover is soft PVC, is processed into the gum cover of a fixed structure by extrusion molding.The main component of magnetic stripe is by bonded ferrite material powder and synthetic rubber, the technique such as, calendering formation shaping by composite co-extruding, injection moulding and make there is flexibility, elasticity and can the permanent magnet of distortion.Strip, web-like, sheet and various complicated shape can be processed into.Penetrated by magnetic stripe in the hollow pipe of gum cover, four corners position is seal strip for refrigerator door by welding.
In use there are two kinds of bad phenomenon in refrigerator of the prior art, a kind of is because the suction of gasket is very large, needs suitable dynamics and just can open, and this is for the little people of strength, and the door opening refrigerator has certain difficulty; And when using strength excessive, cause certain harm because action is inappropriate sometimes.Another kind is because de-magnetic phenomenon occurs magnetic stripe, causes a body sealing unreliable, because this reducing the cold storage effect of refrigerator, increasing power consumption, refrigerator even can be caused time serious to use.
Summary of the invention
The present invention is the weak point for avoiding existing for above-mentioned prior art, provides a kind of electromagnetic door seal, utilizes electromagnetic attraction to ensure the sealing of refrigerator door and casing; Also can easily open the door simultaneously.
The present invention is that technical solution problem adopts following technical scheme:
The design feature of electromagnetic door seal of the present invention is: comprise gum cover, rubber magnetic stripe, spiral winding, the first toroidal conductor and the second toroidal conductor; Wherein, load described rubber magnetic stripe in described gum cover, imbed described first toroidal conductor in described rubber magnetic stripe, the periphery of described rubber magnetic stripe is wound with described spiral winding; Corresponding with the position of described first ring wire on the mouth frame that described second toroidal conductor is arranged on casing.
The design feature of electromagnetic door seal of the present invention is also:
The state that arranges of closing the door is, the first toroidal conductor and box-frame toroidal conductor no power; DC current is passed in spiral winding;
Enabling arranges state, passes into the contrary DC current in direction, no power in spiral winding in the first toroidal conductor and the second toroidal conductor.
The design feature of electromagnetic door seal of the present invention is also:
Refrigerator door handle arranges gauge tap, controls the power on/off state of the first toroidal conductor, the second toroidal conductor and spiral winding with described gauge tap.
Arrange described gauge tap for touching switch, and to arrange the touched state of described touching switch be door opening state, non-touching state is for closing door state.
Compared with the prior art, beneficial effect of the present invention is embodied in:
1, the present invention arranges the suction-combining force that electromagnetic door seal effectively improves gasket and casing, is ensureing, at closing time while seal case, to reach the effect of easily opening the door;
2, present invention effectively prevents the phenomenon that magnetic stripe takes off magnetic, extend magnetic stripe service life.
Accompanying drawing explanation
Fig. 1 is refrigerator door schematic diagram of the present invention;
Fig. 2 is refrigerator body schematic diagram of the present invention;
Number in the figure: 1 spiral winding, 2 first toroidal conductors, 3 bodies, 4 second toroidal conductors, 5 casings.
Detailed description of the invention
See Fig. 1, Fig. 2, arranging electromagnetic door seal in the present embodiment is:
In the present embodiment, electromagnetic door seal comprises gum cover, rubber magnetic stripe, spiral winding, the first toroidal conductor and the second toroidal conductor; Wherein, load rubber magnet bar in gum cover, imbed the first toroidal conductor 2 in rubber magnetic stripe, the periphery of rubber magnetic stripe is wound with spiral winding 1; Corresponding with the position of first ring wire on the mouth frame that second toroidal conductor 4 is arranged on casing 5.
The state that arranges of closing the door is, the first toroidal conductor 2 and the second toroidal conductor 4 no power; DC current is passed in spiral winding 1;
Enabling arranges state, in the first toroidal conductor 2 and the second toroidal conductor 4, pass into the contrary DC current in direction, no power in spiral winding 1.
In concrete enforcement, gauge tap can be set on the handle of refrigerator door 3, control the power on/off state of the first toroidal conductor 2, second toroidal conductor 4 and spiral winding 1 with gauge tap.Arrange gauge tap for touching switch, and to arrange touching switch touched state be door opening state, non-touching state is for closing door state.
During enabling, by the dc source of touching switch cutoff spiral winding, and the contrary DC current in direction is passed in the first toroidal conductor and the second toroidal conductor, the repulsive force between refrigerator door and casing is produced with this, power-assisted is provided for opening the door, in order to make this power-assisted comparatively balanced in doorframe surrounding, the plane that should arrange the first toroidal conductor place is parallel with the plane at the second toroidal conductor place.
Close the door period, touching switch cuts off electric current in the first toroidal conductor and the second toroidal conductor because of reply, and connects the operation source of spiral winding, forms electromagnet with this, and ensures the positiver sealing between refrigerator door and refrigerator body with electromagnetic force.
Touching switch also can be temperature detect switch (TDS), when user points touching temperature detect switch (TDS), is door opening state, otherwise for closing door state.
In concrete enforcement, the size of repulsive force can be changed to adapt to the air pressure of gasket by regulating size of current in the first toroidal conductor and the second toroidal conductor; For spiral shell type coil, then can by changing coil turn and size of current to reach best the suction-combining force.
