In other words, the configuration shown there is to form a recess in the front of the door of the freezer compartment of the refrigerator, store the control circuit board there, and conceal this recess with a cover plate (operation panel). The switches, etc. on the board are exposed.
これによって冷蔵庫の温度設定等を扉の前面に於いて容
易に行える様にしている。This allows you to easily set the temperature of the refrigerator from the front of the door.

への侵入を防止していた。(c) Problems to be Solved by the Invention When electrostatic noise enters such a circuit board, it becomes a cause of malfunction of the refrigerator. However, in winter, etc., the refrigerator user's body is easily charged with static electricity, and since the cover plate is usually made of a synthetic resin (insulator) with good moldability, it is easy to use your fingers when trying to operate the switch. If the switch is placed close to the switch, current (noise) due to static electricity will easily enter the circuit board through the switch surface. Therefore, in the past, a steel plate was installed near the switch on the back of the cover plate, and this was connected to the grounded outer box of the refrigerator with a lead wire, thereby allowing the static electricity from the switch to escape to the steel plate and preventing it from invading the circuit board. Was.
しかし乍ら斯かる構成であると静電気を逃がす為の鉄板

凹所の深さが浅くなって来ているため、鉄板と回路基板
が接近し斯かる傾向が強くなる問題があった。However, with this configuration, since the iron plate for dissipating static electricity is located in the recess, the static electricity from the switch does not go towards the iron plate but towards the circuit board located in the same recess, which does not provide sufficient noise countermeasures. was there. In particular, as the depth of the recesses has become shallower in recent years, there has been a problem that the iron plate and the circuit board are closer to each other and this tendency becomes stronger.

A cover plate that hides the storage compartment and exposes operating parts such as switches from the control circuit board, a decorative plate that has a conductive thin plate on the back and is attached to the front of the cover plate, and a decorative plate that comes into contact with the back of the thin plate and exposes the control circuit board. The refrigerator is provided with a conductive spring member for forming an electric path between the thin plate extending in the direction of the partition plate and penetrating the cover plate without contacting the substrate and the partition plate.

Furthermore, since the thin plate is located on the front surface of the cover plate, a distance between the thin plate and the control circuit board can be secured even if the storage area becomes shallow. Furthermore, even if the distance between the thin plate and the partition plate changes, the spring member can expand and contract to hold the electric circuit.

。(G) Effects of the Invention According to the present invention, static electricity that tends to flow into the control electric circuit of the refrigerator when a switch or the like is operated is discharged to the ground from a conductive thin plate located near the electric circuit through a spring member. This prevents malfunctions caused by static electricity in electric circuits. In particular, since the thin plate is located on the front side of the cover plate closest to the fingers, rather than inside the storage part, even if the depth of the storage part becomes shallow, the distance between the control circuit board and the thin plate can be secured, and reliable noise countermeasures can be taken.
又、薄板と区画板間の距離に誤差が生じてもバネ部材の
伸縮によって両者間の電路が確実に形成される等の効果
を奏する。Further, even if an error occurs in the distance between the thin plate and the partition plate, the expansion and contraction of the spring member ensures the formation of an electric path between the two.
