Illumination system for chest type refrigerator

Abstract

The invention relates to the technical field of refrigerators and freezers in household appliances, in particular to an illumination system for a chest type refrigerator. The invention provides the illumination system which can save energy, has compact structure, and can automatically realize on and off of an illuminating lamp in the refrigerator along with the opening and closing of a door without human additional interference. The illumination system for the chest type refrigerator of the invention comprises an LED lamp (3) arranged on the refrigerator door body (1) and a magnetic control switch for controlling the on and off of the LED lamp (3). The invention has an explosion-proof function, and can be suitable for the refrigerator products using flammable and explosive R600a or R290 and the like as a refrigerant.

Description

technical field [0001] The invention relates to the technical field of refrigerators and refrigerators in household electrical appliances, and more specifically relates to a lighting system for a refrigerator with a top-opening door. Background technique [0002] The volume of freezer products on the market is getting larger and larger, and the structure of the freezer itself is relatively deep. When the ambient light source cannot directly shine inside the cabinet, the light is often blocked by the tall and wide cabinet itself and cannot reach the cabinet. Items inside. Adding a lighting system inside the freezer to achieve auxiliary lighting for the items in the cabinet has become an important function of refrigerated products. [0003] At present, the horizontal freezer products with in-cabinet lighting on the market mostly use small-volume and low-power incandescent lamps or fluorescent lamps, and the control switches mostly use mechanical switches that are toggled by e...

AI Technical Summary

Problems solved by technology

However, incandescent lamps generate heat, consume a lot of energy, and have dim light

The main disadvantage is that the tungsten wire of the bulb is easily broken during frequent door opening and closing; the fluorescent lamp is large in size and occupies the effective volume in the cabinet, which is not convenient for use in the cabinet; the ball rolling weight switch is limited by its own structure and has a large volume ; And there are hidden dangers in terms of functional reliability and safety: sparking occurs at the moment when the steel ball rolling is connected or disconnected from the circuit, and the surface of the iron ball is oxidized and poorly contacted after long-term use

At present, most freezer products use R600a or R290 refrigerants as refrigerants. These refrigerants are flammable and explosive. Once the internal leakage is easily ignited by cremation

Therefore, the ball rolling type weight switch cannot be used in the cabinet

Proximity switches are also used in vertical freezers and refrigerators. The control system switch and the lamp are located in different positions. The lamp is located inside the cabinet and the switch is located outside the cabinet, but the connection between them requires a long wire and the structure is not compact enough.
