Operation display device

Abstract

The invention provides an operation displaying device with a perfect visuality, whose liquid crystal display is difficult to deterioration and dew. The control device is equipped with a liquid crystal display which can be seen through the transparent window in the panel cover, and a transparent box for covering the liquid crystal display. The bottom face of the transparent box has a cut which forms a gap from the control device when installing on the control device. A wet-proof filling-closing agent is filled at the front and back surface inside and outside the control device. Additionally, one or a plurality of small holes are disposed on the side face of the transparent box for covering the liquid crystal display to maintain the same air pressure inside and outside the transparent box. Thus, the surface of the liquid crystal display will not be dew and deterioration and the reliability will be improved.

Description

technical field [0001] The present invention relates to an operation display device provided with a liquid crystal display unit capable of performing display corresponding to an operation of an operation key unit. Background technique [0002] Such a conventional operation display device used in a washing machine or the like has the configuration shown in FIGS. 6 to 8 . The composition thereof is described below. [0003] 6 is a schematic top view of a conventional washing machine provided with an operation display device, FIG. 7 is an exploded oblique view of the operation display device, and FIG. 8 is a schematic sectional view of the operation display device. [0004] The washing tub (not shown in the figure) of the washing machine is covered by the machine cover 2 in a freely openable and closed manner, and the operation display panel 1 is installed on the front of the machine cover 2 (the side closer to the user) as shown in Figure 6 , the top surface of the operation...

AI Technical Summary

Problems solved by technology

When performing pasting operations, a gap for absorbing thermal expansion and contraction needs to be reserved between the inner edge of the operation display unit 8 and the outer edge of the panel patch 3, which is not only poor in visibility, but also easily Accumulation of dust and moisture

In addition, in the case where the power-on switch 7a and the power-off switch 7b are arranged near the edge of the above-mentioned panel patch 3, etc., since the backside of the power-on switch 7a and the power-off switch 7b is not used for The adhesive for bonding the panel sticker 3, so the adhesive bonding width between the outer peripheral part of the panel sticker 3 and the power on switch 7a and the power off switch 7b will become narrow, and this width is very narrow. The adhesive force generated by the pasted part will decrease

In this way, when the power-on switch 7a and the power-off switch 7b are pressed, it is easy to cause the problem that the panel sticker 3 starts to peel off from this part.

[0015] In addition, since only display elements 15 such as light-emitting diodes are used for display operations, there is no change in strength and weakness in the display, and there is no difference between the display state that often appears and the display state that does not appear frequently, so it is difficult for the user to notice

[0016] In addition, in the case of using warm water for laundry in winter, the heat generated by the warm water will enter the operation mode display units 6a, 6b, 6c, etc., causing water droplets to adhere to these display units, making the display difficult to see and damaged. aesthetic problem
