Abstract
The invention relates to electric equipment, in particular to a refrigerator provided with an electromagnet on a refrigerator body door. The refrigerator comprises a refrigerator body and a cabinet door; a first magnet is mounted in the refrigerator body door; and a second magnet is mounted on the cabinet door. The refrigerator is characterized in that at least one of the first magnet and the second magnet is an electromagnet; the electromagnet is connected with a power supply to form a circuit; a switch is mounted in middle of the circuit; the switch is mounted on a hand buckle of the cabinet door; when the hand buckle is pulled, the switch is cut off; the switch is a replacement switch; the replacement switch respectively has two buttons; the two buttons are respectively mounted inside and outside the hand buckle, and are respectively a first button inside and a second button outside; when the first button is pressed, the magnetic pole generated by the electromagnet is homosexually opposite to the magnetic pole of the other magnet; and when the second button is pressed, the current direction is converted, and the magnetic pole generated by the electromagnet is heterosexually opposite to the magnetic pole of the other magnet. The refrigerator has the advantages of lower strength during opening the cabinet door and labor saving.
Description
Technical field
The present invention relates to electrical equipment, more particularly to refrigerator.
Background technology
Refrigerator includes casing and cabinet door, and it is casing doorway to install on casing where cabinet door, in order that cabinet door is closed tightly,
First magnet is installed at casing doorway, the second magnet, the first magnet and the second magnet poles opposite sex correspondence are installed in cabinet door
Arrange, cabinet door there can be the strength near cabinet doorway, reach the effect for closing cabinet door tight；In prior art, the first magnetic
Iron and the second magnet are all permanent magnets（I.e. non-electromagnet）, such cabinet door always have near casing doorway strength,
Have the shortcomings that when opening cabinet door firmly larger, hard.
The content of the invention
The purpose of the present invention is aiming at disadvantages mentioned above, there is provided strength is less during a kind of opening cabinet door, the ice that saves labour
Case --- the refrigerator of electromagnet is installed at casing doorway.
The technical scheme is that what is be achieved in that：The refrigerator of electromagnet is installed at casing doorway, including casing and
Cabinet door, installs the first magnet at casing doorway, and the second magnet is installed in cabinet door, it is characterized in that：Described the first magnet and
Second magnet at least first electromagnet, electromagnet connection power supply formed circuit, in circuit between install switch, described switch
Hand installed in cabinet door is buckled, and is switched off when pulling hand button.
Further say, described switch is permutator, permutator has respectively two buttons, two button difference
It is respectively the first button of the inside and the second button of outside installed in the inside and outside of hand button；When pressing the first button, electricity
The magnetic pole and the magnetic pole same sex of another magnet that magnet is produced is relative；When pressing the second button, sense of current conversion, electromagnet is produced
Raw magnetic pole and the magnetic pole opposite sex of another magnet is relative.
The invention has the beneficial effects as follows：
Strength is less, save labour when such refrigerator has the advantages that to open cabinet door；
Described switch is permutator, and permutator has respectively two buttons, and two buttons are separately mounted in hand button
Face and outside, are respectively the first button of the inside and the second button of outside；When pressing the first button, the magnetic pole that electromagnet is produced
It is relative with the magnetic pole same sex of another magnet；When pressing the second button, sense of current conversion, the magnetic pole and another that electromagnet is produced
The magnetic pole opposite sex of individual magnet is relative, also has the advantages that to open the door, more saves labour at closing time.
Description of the drawings
Fig. 1 is structural representation when cabinet door of the present invention is opened.
Fig. 2 is structural representation when cabinet door of the present invention is closed.
Fig. 3 is the line map of solenoid circuit.
Wherein：1st, cabinet 2, cabinet door 3, the first magnet 4, the second magnet 5, hand button 6, permutator 7,
One button 8, the second button.
Specific embodiment
Below in conjunction with the accompanying drawings the invention will be further described.
As shown in Figure 1, 2, the refrigerator of electromagnet, including casing 1 and cabinet door 2 are installed, on casing doorway at casing doorway
The first magnet 3 is installed at place, and the second magnet 4 is installed in cabinet door, be it is characterized in that：Described the first magnet and the second magnet at least its
One is electromagnet, and electromagnet connection power supply forms circuit, in circuit between switch is installed, the hand of described switch installed in cabinet door
On button 5, switch off when pulling hand button.
So, when opening cabinet door, hand button is pulled, the circuit for producing magnetic to electromagnet disconnects, and electromagnet does not have an electric current, two
It is unattractive between individual magnet, easily cabinet door is opened.
Further say, described switch is permutator 6, permutator has respectively two buttons, two buttons point
Not An Zhuan hand button inside and outside, be respectively the inside the first button 7 and outside the second button 8；Press the first button
When, the magnetic pole and the magnetic pole same sex of another magnet that electromagnet is produced is relative；When pressing the second button, sense of current conversion, electricity
The magnetic pole and the magnetic pole opposite sex of another magnet that magnet is produced is relative, as shown in Figure 3.So when cabinet door is closed, two magnet
Between produce be attraction, easily cabinet door is closed, when opening closes cabinet door, between two magnet produce be repulsive force,
Easily cabinet door is opened.
The part of dotted line represents that in another state similar circuit diagram also has many, and those skilled in the art should know.
The specific embodiment of the present invention is the foregoing is only, but the architectural feature of institute's protection domain of the present invention is not limited to
This, in the field of the invention, the patent in the present invention is all covered in the change or modification made to any those skilled in the art
In the range of.
