In this embodiment, the light emitting lamp 130 and the key 120 are both installed on the first side 111 of the substrate 110, i.e. the light signal emitted by the light emitting lamp 130 can be seen on the second side 112 of the substrate 110, and the bonding pads and copper foils are not required to be arranged on both sides of the substrate 110, so that the cost of the circuit board 100 is saved, and the light emitting lamp 130 is not required to be arranged on the second side 112 of the substrate 110, so that the space of the second side 112 of the substrate 110 is not required to be occupied, and the space occupation of the circuit board 100 is also saved.
For example, the light emitting lamp 130 is electrically connected to the key 120, the key 120 may be used to control light emission of the light emitting lamp 130, the key 120 may be, for example, a user interface key 120, the light emitting lamp 130 may be, for example, a status indicator lamp, a user may control the home appliance device to enter different working states through the key 120, and according to the different working states, the light emitting lamp 130 may be automatically turned on or emit different lights.
The circuit board 100 may be divided into a single board, a double board, or a multi-layer board, and many home appliances employ a single board or a double board, but the cost of a single board is much lower than that of a double board.
The single-layer board refers to a printed board with copper foil on one side, and the double-layer board refers to a printed board with copper foil on both the bottom layer and the top layer. The printed board is assembled with electronic components to form a circuit board 100, which is mounted on some parts of the whole machine.
For example, please refer to fig. 2, fig. 2 is a schematic diagram of a second structure of a circuit board according to an embodiment of the present application. The light-emitting lamp 130 and the key 120 are installed by using a single-layer board, and the single-layer board is only provided with a bonding pad and a copper foil on the first side 111, and the light-emitting lamp 130 is an LED lamp, for example, when the installation position space is large, an in-line LED lamp is generally adopted.

Whereas the substrate 110 of the circuit board 100 in this embodiment is a single-layer board. Compared with the double-layer plate, the cost of the single-layer plate is about 1/3, and the cost advantage is obvious. Therefore, the cost of the circuit board 100 can be reduced in the embodiment of the application, so that the selling price of the household electrical appliance is reduced, and the market competitiveness of the product is improved.
The light emitting lamp 130 is a chip device in this embodiment, for example. The first side 111 of the circuit board 100 is provided with a first bonding pad and a second bonding pad, the first bonding pad and the second bonding pad are located at two sides of the through hole 140, the light emitting lamp 130 comprises a first connection end and a second connection end, the light emitting surface is arranged between the first connection end and the second connection end, the first connection end is welded with the first bonding pad, and the second connection end is welded with the second bonding pad.

Due to the limitation of the height space of the box cover 300, if the in-line light emitting lamp 130 is mounted on the second side 112 of the single-layer board as in fig. 2, the in-line light emitting lamp 130 may not be mounted. If the patch type light emitting lamp 130 is mounted on the second side 112 of the double-layer board as shown in fig. 3, the second side 112 of the double-layer board needs to be provided with a pad and a copper foil, which increases the cost of the circuit board 100, but in this embodiment, the substrate 110 of the circuit board 100 may be a single-layer board, the first side 111 is provided with a pad and a copper foil, and the substrate 110 is provided with a through hole 140, so that the light emitting surface of the light emitting lamp 130 is at least partially opposite to the through hole 140, and the light signal emitted by the light emitting lamp 130 can pass through the through hole 140, so that the light signal emitted by the light emitting lamp 130 can be seen on the second side 112 of the substrate 110.
