Abstract

The utility model relates to a refrigerator with a noncontact switch of a lighting lamp, which comprises a refrigerator body and a refrigerator door. The refrigerator is provided with at least one dry tongue reed pipe and at least one permanent magnet which is installed beside the door of the refrigerator and hidden below a plastics supercrust inside, and the dry tongue reed pipe is installed on the refrigerator body corresponding to the permanent magnet and hidden below a plastics supercrust inside. Through the opening and the closing of the refrigerator door, magnetic fields are close to or depart from the dry tongue reed pipe, thus making the dry tongue reed pipe switched on or cut off an illuminating circuit. Because wearing phenomena of switches are eliminated, the life time is long. The utility model has the characteristics of low cost, convenient installation and low cost.

Description

Refrigerator with uncontact switch of lighting lamp

The utility model relates to a kind of refrigeration plant, is family and the extensive use of institute of unit.

Refrigerator generally all is equipped with lighting bulb.But the gauge tap of lighting bulb generally all adopts touch switch.When door of refrigerator opens or closes, promote gauge tap contact closure or disconnecting circuit, thereby open bright or extinguish lighting bulb.Owing to reasons such as wearing and tearing, dusts, this class switch is often malfunctioning easily, makes troubles for user and manufacturer.

Task of the present utility model is the weak point that overcomes above-mentioned prior art, and a kind of novel fridge is provided, and the luminous lamp switch that it is equipped with has simple in structure, is active in one's movements, and the characteristics that working life is long again are to satisfy people's lives and requirements of one's work.

The technical solution adopted in the utility model is: embed at least one block of permanent magnet on the chamber door of each refrigerator, embed a dry type tongue spring tube on the casing with on the corresponding position of this permanent magnet, the two ends lead-in wire of this dry type tongue spring tube inserts in the circuit of illuminating lamp.

Further specify below in conjunction with embodiment shown in the drawings.

Fig. 1 is the schematic diagram of a specific embodiment of the utility model.

Fig. 2 is the structure diagram of dry type tongue spring tube.

As shown in the figure, the chamber door limit of refrigerator is embedded with a permanent magnet 1, is embedded with a dry type tongue spring tube 2 with the corresponding position of this permanent magnet on the casing.The structure of dry type tongue spring tube can represent that the two ends lead-in wire of this reed capsule inserts respectively in the circuit of illuminating lamp with Fig. 2.

Below the permanent magnet 1 interior plant chamber door limit plastic surface layer, outside air is isolated, prevented being infected with of extraneous dust and foul by this plastic surface layer.Below the also interior plant plastic surface layer of thousand formula reed capsules 2 on the casing, contacting of blocks dust and other foul completely cuts off outside air.If they are contained in outside the plastic surface layer certainly, do not influence serviceability yet.The quantity of dry type tongue spring tube and permanent magnet is decided according to the quantity of illuminating lamp, also can be according to the decision of design needs.

When door of refrigerator was closed, permanent magnet 1 was near dry type tongue spring tube 2.Affected by magnetic fields, the reed in the dry type tongue spring tube moves with regard to being magnetized, and lighting lamp circuit is disconnected, and lamp just extinguishes.Otherwise when door of refrigerator was opened, permanent magnet 1 left dry type tongue spring tube 2, and externally-applied magnetic field disappears, thereby reed just recovers the closed lighting circuit of original state, and lamp just opens bright.

Adopt this kind technical scheme, not only light switch is swift in motion, sensitivity; And because unlatching is contactless, fundamentally eliminated the wear phenomenon of switch. Thereby it is long to have a life-span, does not have the advantage of wearing and tearing. In addition, dry type tongue spring tube is approved product, and is on sale on the market, and cheap, also has again low characteristics of simple in structure, easy for installation, cost.

Claims

1, the refrigerator of contactless luminous lamp switch is housed, comprise chamber door and casing etc., it is characterized in that each refrigerator is equipped with at least one dry type tongue spring tube and at least one block of permanent magnet, said permanent magnet embeds the door limit of door of refrigerator, said dry type tongue spring tube then embed on the casing with the corresponding position of permanent magnet, two ends of dry type tongue spring tube lead-in wires inserts in the lighting circuit respectively in addition.

2,, it is characterized in that said dry type tongue spring tube 2 is built in below the plastic surface layer of casing by the described refrigerator of claim 1.

3,, it is characterized in that said permanent magnet 1 is built in below the plastic surface layer of chamber door by claim 1 or 2 described refrigerators.
