Description

Touch module and washing machine

Technical Field

The utility model belongs to the technical field of touch panel, concretely relates to touch module and washing machine.

Background

The washing machine is a daily necessary household appliance of modern families and is usually arranged in a place with concentrated dirt, dust and water, so that a user needs to clean the panel of the washing machine frequently, the traditional thin film micro-motion key or mechanical key is easily damaged, and the risk of water immersion of a display screen exists.

In addition, along with the development of AI artificial intelligence, thing networking and intelligent house, washing machine must be given more functions to become more humanized and intelligent, under this trend, traditional film fine motion button or mechanical button control interface can restrict washing machine's intelligent development, and in the face of the increase of these functional requirements, the user urgently needs a more directly perceived simpler operation interface mode.

At present, the panel of the washing machine on the market mostly adopts a mode of a thin film micro-motion key mechanical key to control related functions, and the key is convenient to operate, mature in technology, low in cost and popular.

In addition, the power switch used in the current washing machine is generally a mechanical movable switch, the mechanical pressing type power switch is easy to enter water or be affected by water vapor to damage a computer board, so that safety accidents are caused, and in order to solve the waterproof problem, a very complex waterproof structure and a waterproof sealing element are required to be added, so that the cost is increased and the installation is difficult. Based on this, the touch technology implemented by adopting a capacitive or piezoelectric sensor has been applied to high-end models of pulsator full-automatic washing machines in batches. The washing machine panel adopting the touch technology and realized by the capacitive or piezoelectric sensor has better waterproof performance and easier cleaning than the traditional touch panel adopting a film micro-motion key or a mechanical key, but cannot solve the problem of touch failure in a humid environment. However, the capacitive pressure sensor needs a mechanical stroke of the conductive spring or the conductive elastic sheet to achieve power on and off, and also has a mechanical fatigue problem of the conventional key, and research and feedback in recent markets show that the laundry machine using the two touch technologies often has a phenomenon of poor touch, and particularly has a high probability of failure when the ambient humidity is high, such as in the rainy season in the south.

Therefore, in order to solve the problems that the touch technology implemented by using a capacitive or piezoelectric sensor is susceptible to a humid environment, so that the touch effect of the whole machine is easily deteriorated and the waterproof and steam-proof capabilities are low, it is necessary to provide a new touch module and a washing machine based on the same.
