Display apparatus of washing machine

Abstract

The invention relates to a display device of a washing machine, which comprises a front control panel provided with a plurality of display windows and a computer board that is internally arranged in the display device. Positions of the computer board, corresponding to the display windows, are provided with a plurality of display lamps. A keyboard board is arranged between the front control panel and the computer board and provided with a case-shaped lamp bracket in which a plurality of lamp bracket holes corresponding to the positions and the number of the display lamps are arranged. The display lamps are respectively arranged in the corresponding lamp bracket holes and light guide pillars which have the shapes matching with the lamp bracket holes and take the shape of pillars are inserted into the lamp bracket holes. The top parts of the light guide pillars are inserted into lamp holes at the rear of the front control panel. The device ensures that lamplight can directly shine on the display window so as to completely cut off spaces for light leakage, thereby effectively avoiding that the lamplight emanates outside the lamp holes and also avoiding an optical crosstalk phenomena caused by the misplacement of lamp holes and comparatively long distant range from the computer board to the front control panel. When a user uses the washing machine, the operative mode of the washing machine can be more accurately determined so as to improve the identifiability.

Description

technical field [0001] The invention relates to a display device of a washing machine, in particular to a display device which is located on the front control panel of the washing machine and displays through a display element. Background technique [0002] On the front control panel of the existing washing machine, a plurality of control buttons and a display window for displaying the working state of the washing machine are provided. Inside the front control panel, a computer board for controlling the running state of the washing machine is provided. LED lights that illuminate the display windows on the front control panel of the washing machine. Since the light is diverging to the surroundings, in the absence of space to block the light or lead light, the light seen from the front control panel of the washing machine has the phenomenon of cross-lighting between the light holes, so that more than two light holes can be connected at the same time. Luminous, easy to use the...

Problems solved by technology

However, there are still deficiencies in this invention. First, the box-type light bracket is arranged on the control circuit board, which will inevitably occupy a large space on the circuit board with dense wiring, which is not conducive to the reduction of the circuit board volume. The light bracket is directly formed on the control circuit board, and the hollow protrusion formed by the light hole on the control panel is inserted into the light hole. When the washing machine is running, the resulting vibration will form the extrusion of the front control board and the light frame on the control circuit board, which is not conducive to the safety of the circuit.

Second, if there is a gap between the front control panel and the upper surface of the lamp holder, causing the hollow convex part to escape from the inside of the lamp hole, light leakage will still occur

The control device 30 is also provided with a display cabin 34, the display cabin 34 is provided with light diffusion members 35 respectively covering the display elements 32, the heights of adjacent light diffusion members 35 are set to be different, and the operation panel The portion 18 is provided with a height difference 18a corresponding to the different heights of the light-diffusing member 35. This invention directly connects the light-diffusing member 35 of the display cabin 34 with the light-diffusing member 36 of the control panel 18. Defects that the processing technology requirements are too harsh
