Abstract
The invention discloses an electromagnetic door seal which is characterized by comprising a rubber sleeve, a rubber magnetic strip, a spiral coil, a first annular guide line and a second annular guide line, wherein the rubber magnetic strip is mounted inside the rubber sleeve; the first annular guide line is buried in the rubber magnetic strip; the periphery of the rubber magnetic strip is wound by the spiral coil; the second annular guide line is arranged on the door frame of a refrigerator body and corresponds to the first annular guide line in position. According to the electromagnetic door seal, the sealing performance of a refrigerator door body and the refrigerator body can be ensured by using electromagnetic force, and meanwhile, the door can be opened easily.
Description
Technical field
The present invention relates to seal strip for refrigerator door.
Background technology
Seal strip for refrigerator door is to be used between refrigerator door and casing, to be used for the refrigerator accessory of sealing.In order to prevent cold air and extraneous hot gas exchange heat in refrigerator, in Men Tiyu casing junction, post magnetic stripe, i.e. magnetic door seal, relies on the magnetic force of magnetic stripe, together with refrigerator door is tightly inhaled with casing.Gasket is comprised 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, and that by techniques such as composite co-extruding moulding, calendering formation, injection mouldings, makes has flexibility, elasticity and a permanent magnet that can distortion.Can be processed into strip, web-like, sheet and various complicated shape.Magnetic stripe is penetrated 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, need to have suitable dynamics just can open, and this is for the little people of strength, and the door of opening refrigerator has certain difficulty; And when using strength excessive, sometimes because moving inappropriate certain harm that causes.Another kind is because de-magnetic phenomenon occurs magnetic stripe, causes a body sealing unreliable, has therefore reduced the cold storage effect of refrigerator, increases power consumption, when serious, even can cause refrigerator to use.
Summary of the invention
The present invention is for avoiding the existing weak point of above-mentioned prior art, and a kind of electromagnetic door strip of paper used for sealing is provided, and utilizes electromagnetic attraction to guarantee 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 strip of paper used for sealing of the present invention is: comprise gum cover, rubber magnetic stripe, spiral winding, the first toroidal conductor and the second toroidal conductor; Wherein, pack described rubber magnetic stripe in described gum cover into, imbed described the first toroidal conductor in described rubber magnetic stripe, the periphery of described rubber magnetic stripe is wound with described spiral winding; Described the second toroidal conductor be arranged on casing mouth frame on and corresponding with the position of described first ring wire.
The design feature of electromagnetic door strip of paper used for sealing 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; In spiral winding, pass into DC current;
The state that arranges that opens the door is in the first toroidal conductor and the second toroidal conductor, to pass into the DC current of opposite direction, no power in spiral winding.
The design feature of electromagnetic door strip of paper used for sealing of the present invention is also:
On refrigerator door handle, gauge tap is set, with described gauge tap, controls the power on/off state of the first toroidal conductor, the second toroidal conductor and spiral winding.
Described gauge tap is set for touching switch, and the touched state of described touching switch is set is door opening state, non-touching state is the state of closing the door.
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 strip of paper used for sealing has effectively improved gasket and casing, when guaranteeing at closing time seal case, reaches the effect of easily opening the door;
2, the present invention has effectively avoided the phenomenon of the de-magnetic of magnetic stripe, extends 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.
The specific embodiment
Referring to Fig. 1, Fig. 2, electromagnetic door strip of paper used for sealing be set in the present embodiment be:
In the present embodiment, electromagnetic door strip of paper used for sealing comprises gum cover, rubber magnetic stripe, spiral winding, the first toroidal conductor and the second toroidal conductor; Wherein, pack rubber magnet bar in gum cover into, imbed the first toroidal conductor 2 in rubber magnetic stripe, the periphery of rubber magnetic stripe is wound with spiral winding 1; The second toroidal conductor 4 be arranged on casing 5 mouth frame on and corresponding with the position of first ring wire.
The state that arranges of closing the door is, the first toroidal conductor 2 and the second toroidal conductor 4 no powers; In spiral winding 1, pass into DC current;
The state that arranges that opens the door is in the first toroidal conductor 2 and the second toroidal conductor 4, to pass into the DC current of opposite direction, no power in spiral winding 1.
In concrete enforcement, can on the handle of refrigerator door 3, gauge tap be set, with gauge tap, control the power on/off state of the first toroidal conductor 2, the second toroidal conductor 4 and spiral winding 1.Gauge tap is set for touching switch, and touching switch touched state is set is door opening state, non-touching state is the state of closing the door.
While opening the door, by touching switch, cut off the dc source of spiral winding, and in the first toroidal conductor and the second toroidal conductor, pass into the DC current of opposite direction, with this, produce the repulsive force between refrigerator door and casing, power-assisted is provided for opening the door, in order to make this power-assisted comparatively balanced in doorframe surrounding, the plane at the first toroidal conductor place should be set and the plane at the second toroidal conductor place is parallel.
During closing the door, 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, with this, forms electromagnet, and guarantees the positiver sealing between refrigerator door and refrigerator body with electromagnetic force.
Touching switch can be also temperature detect switch (TDS), when user's finger touches temperature detect switch (TDS), is door opening state, otherwise is the state of closing the door.
In concrete enforcement, can be by regulating size that in the first toroidal conductor and the second toroidal conductor, size of current changes repulsive force to adapt to the air pressure of gasket; For spiral shell type coil, can be by changing coil turn and size of current to reach best the suction-combining force.
