Description

Technical Field

[0001] This utility model relates to the field of household appliance protection technology, specifically to a wiring indicator panel for household appliances. Background Technology

[0002] Common types of circuit faults in household appliances include operation without neutral wire, reverse neutral and live wire connection, and grounding failure. Among them, a broken neutral wire can cause abnormal voltage rise and burn out the appliance windings; a reverse neutral and live wire connection can cause the appliance casing to become accidentally live (such as the metal casing of a water heater), which can cause electric shock if touched, and may even cause the residual current device (RCD) to fail; a broken or loose ground wire can prevent the current from being conducted to the ground when there is a leakage, and the human body can easily become a conductive path, causing the risk of electric shock.

[0003] Currently, fault protection for household appliances during use relies on the main switch, such as air switches, over / under voltage switches, and residual current circuit breakers. When some appliances with higher electrical risks malfunction, the fault is often only discovered after the main switch has been disconnected, requiring investigation to pinpoint the fault location. This prevents timely indication and warning of wiring faults, posing a potential safety hazard to household electricity. Incorrect or unstable wiring of household appliances is the main cause of these malfunctions.

[0004] Therefore, there is an urgent need to design a wiring indicator panel for household appliances that can provide users with timely indications of wiring faults. Summary of the Invention

[0005] To address the aforementioned problems, this utility model provides a wiring indicator panel for household appliances, comprising a panel body with positioning and mounting holes. The back of the panel body, from top to bottom, is provided with a connection plate area, a wiring area, and a routing area. A circuit board is connected to the connection plate area, and a terminal block is connected to the wiring area. The terminal block includes a live wire wiring unit, a neutral wire wiring unit, and a ground wire wiring unit. Each of the live wire wiring unit, the neutral wire wiring unit, and the ground wire wiring unit includes a conductive base and a conductive fastener. The conductive base is connected to the terminal block, and the conductive fastener is connected to the inlet and outlet ends of the conductive base, respectively. A power-collecting plate is connected to the circuit board, and the power-collecting plate is electrically connected to the inlet end of the conductive base. A light-emitting device is connected to the side of the circuit board facing the panel body. An indicator area is provided on the panel body directly opposite the light-emitting device. An outlet hole is provided on the side of the routing area away from the terminal block.

[0006] The present invention is further provided with a wiring portion protruding from the lower front part of the panel body, and the wiring portion having a wiring cavity communicating with the wiring area.

[0007] The present invention is further configured such that the lower end of the wiring section is provided with a conduit joint, the conduit joint is connected to the wiring cavity, and a waterproof connector is connected to the conduit joint.

[0010] The present invention is further configured such that a wiring mark is provided in the connection plate area, and the light-emitting device is a light-emitting diode.

[0011] The present invention is further configured such that the terminal block has three independent conductive cavities, and the conductive cavity has a terminal post on the side away from the panel body. The conductive base is connected to the conductive cavity, the conductive fastener is connected to the terminal post, and the power taking piece is L-shaped. One end of the power taking piece is connected to the circuit board, and the other end of the power taking piece is connected to the conductive cavity.

[0012] The present invention is further configured such that a plug is connected inside the positioning mounting hole, the inner wall of the positioning mounting hole is provided with a positioning step, and the outer side of the plug is provided with a notch opposite the positioning step.

[0013] The present invention is further configured such that accessory connection areas are provided on both sides of the wiring area, accessory positioning plates are provided in the accessory connection areas, accessory positioning cavities are formed between the accessory positioning plates, and at least one accessory positioning plate is provided with an anti-detachment protrusion.

[0014] The present invention is further provided with a sealing groove on the back of the panel body, and a waterproof sealing gasket is provided in the sealing groove.

[0015] The usage method of the household appliance wiring indicator panel in this technical solution is as follows: Connect the external power cord to the input terminals of the live wire wiring unit, neutral wire wiring unit, and ground wire wiring unit. The circuit board obtains the working voltage from the terminal block through the power taking piece, and at the same time detects the actual wiring of each wiring unit.

It can detect abnormalities before or even immediately after a fault occurs, and immediately and intuitively display the fault type on the panel's indicator area through a light-emitting device. It eliminates the need to wait for the main switch to trip before passively discovering the fault, as the indicator signal it emits directly points to the circuit or appliance where the panel is located, greatly shortening the fault location time. Moreover, it can promptly detect faults such as reversed live and neutral wires, broken neutral wires, or missing ground wires, providing early warning of risks before the user touches them, thus avoiding electric shock and preventing electrical fires during the use of household appliances.

The light-emitting device faces the panel indicator area to ensure that fault information is clearly visible. Power is directly drawn from the inlet end through the power take-off plate to power the circuit board without the need for an external power supply. It is easy to install and has a high degree of integration. Attached Figure Description
