Abstract
The utility model discloses a water level measuring device of a full automatic washing machine, which is characterized in that the water level measuring device adopts a water pressure sensor; the water pressure sensor is fixed at the bottom or on the side of a water holding barrel of the washing machine; the measuring end surface of the water pressure sensor is arranged in the water holding barrel of the washing machine or the measuring side surface is in direct contact with water; and the water pressure sensor is connected with a signal acquisition circuit of the washing machine through a conducting wire. The water pressure sensor applied to the utility model by adopting full electronic control can directly measure the altitude variation of the liquid level, can replace the original semi-mechanical water level sensor, have the characteristics of high precision, convenient installation and less influence on the external environment, play a decisive role of improving the product quality, and greatly improve the working efficiency of installation at the same time.
Description
Technical field
The utility model relates to a kind of automatic washing machine, especially relates to a kind of automatic washing machine with hydraulic pressure sensor, belongs to the washing machine mechanical field.
Background technology
Along with the washing machine industry develops rapidly, mechanical type, half mechanical type part is progressively replaced by the electronic zero parts, and traditional being used to measured the sensor of water level and mostly is half mechanical type level sensor, this kind sensor accuracy is low, installation is difficult, be subject to the external environment influence, and then has influence on the measurement quality.
The utility model content
In order to overcome the deficiencies in the prior art, the purpose of this utility model is to provide a kind of level measuring precision height, is convenient to the automatic washing machine with hydraulic pressure sensor that control water level is measured.
The utility model is achieved through the following technical solutions:
A kind of level measurement device of automatic washing machine, it is characterized in that, described level measurement device is a hydraulic pressure sensor, it is fixed on the bottom or the sidepiece of water tub of washing machine, the end face of its measurement then is arranged in the steel ladle of washing machine or the side directly contacts with water, and described hydraulic pressure sensor is connected with the signals collecting circuit of washing machine by lead.
The above-mentioned hydraulic pressure sensor and the fixed form of water tub of washing machine are that screw is fixed or bayonet socket is fixed.
Above-mentioned hydraulic pressure sensor is stainless steel encapsulating structure or overall plastic hermetically-sealed construction.
The beneficial effects of the utility model are: the applied hydraulic pressure sensor of the utility model, has full electronic control, can directly measure the height change of liquid level, can replace original half mechanical type level sensor, have the precision height, easy for installation, suffered external environment influence features of smaller, the quality that improves product there is very important effect, has improved the operating efficiency of installing simultaneously greatly.
