## Abstract

A clothes dryer cabinet has a rear wall with a wire entry opening through which wiring enters into the dryer cabinet. A fuse supporting block is mounted closely adjacent to the wire entry opening and supports fuses which are connected directly to the wiring entering through the wire opening so as to limit or minimize the length of wiring contained in the dryer drum that is not protected by the fuses. This safety feature reduces the chance of fires occurring in the dryer as a result of arcing between wires due to mishandling of the wires, malmanufacturing of the wires or a fire occurring in the dryer.

## Claims

### Claim 1

A clothes dryer having an electrical load, comprising:
a cabinet having a wall;
a power cord mounted on the wall outside of the cabinet, the power cord having a cord neutral wire line and at least one entry live wire line, the neutral line being connected in electrical circuit with the electrical load;
the wall having a wiring entry opening through which the neutral wire line and the at least one entry live wire line pass into, and extend within, the cabinet;
the electrical load being further connected in electrical circuit with at least one load live wire line extending within inside the cabinet; and,
a fuse for each entry live wire line being connected in electrical circuit between a corresponding entry live wire line and a corresponding load live wire line for disconnecting power to the load live wire line and the electrical load, the fuse being located inside the cabinet closely adjacent to the wiring entry opening so as to limit length of the at least one entry live wire line within the cabinet.

### Claim 2 (depends on 1)

The clothes dryer of claim 1 further comprising a fuse supporting block to which the fuse may be mounted, the fuse supporting block being mounted to an inside surface of the wall closely adjacent the wiring entry opening.

### Claim 3 (depends on 2)

The clothes dryer of claim 2 wherein the electrical load comprises at least one motor, and an electronic power supply.

### Claim 4 (depends on 1)

The clothes dryer of claim 1 wherein the wall comprises a rear wall of the cabinet.

### Claim 5

A clothes dryer having an electrical load, comprising:
a cabinet having a wall;
a power cord electrically connected to a terminal box mounted on the wall of the cabinet, one of the power cord and the terminal box having a neutral wire line and at least one entry live wire line, the neutral line being connected in electrical circuit with the electrical load;
the wall having a wiring entry opening through which the neutral wire line and the at least one entry live wire line pass into, and extend within, the cabinet;
the electrical load being further connected in electrical circuit with at least one load live wire line extending within inside the cabinet; and,
a fuse for each entry live wire line is connected in electrical circuit between a corresponding entry live wire line and a corresponding load live wire line for disconnecting power to the load live wire line and the electrical load, the fuse being located inside the cabinet closely adjacent to the wiring entry opening so as to limit length of the at least one entry live wire line within the cabinet.

### Claim 6

A clothes dryer having an electrical load, comprising:
a cabinet having a wall;
a power cord electrically connected to a terminal block mounted on the wall outside of the cabinet, the power cord having a cord neutral wire line and two cord live wire lines respectively connected at the terminal block to a dryer neutral wire line and corresponding ones of two dryer entry live wire lines;
the electrical load being connected in electrical circuit with the dryer neutral wire line and two load live wire lines extending only within the cabinet;
the wall having a wiring entry opening through which the dryer neutral wire line and the two dryer entry live wire lines pass into the cabinet from the terminal box; and,
two fuses each being connected in electrical circuit between a corresponding one of the dryer entry live wire lines and a corresponding one of the load live wire lines for disconnecting power to the corresponding one load live wire line and the electrical load, the fuses being located inside the cabinet closely adjacent to the wiring entry opening so as to limit length of the dryer entry live wire lines within the cabinet.

### Claim 7 (depends on 6)

The clothes dryer of claim 6 further comprising a fuse supporting block to which the fuses are mounted, the fuse supporting block being mounted to an inside surface of the wall closely adjacent the wiring entry opening.

### Claim 8 (depends on 7)

The clothes dryer of claim 7 wherein the electrical load comprises at least one motor, at least one electrical heating element, and an electronic power supply.

### Claim 9 (depends on 6)

The clothes dryer of claim 6 wherein the wall is a rear wall of the dryer.
