Method for judging water fullness state of pressure barrel by water purifier through gravity sensor

Abstract

The invention discloses a method for judging the water fullness state of a pressure barrel by a water purifier through a gravity sensor, and relates to the technical field of the water purifier, a household direct drinking fountain and a commercial drinking fountain. The method comprises the following steps that a gravity sensor device is added onto the pressure barrel arranged inside the water purifier, the weight of the pressure barrel is collected through the gravity sensor, an electric control plate arranged on the water purifier receives the weight information of the pressure barrel collected by the gravity sensing device, when the collected weight information of the pressure barrel reaches the set upper limit, the electric control plate judges that the pressure barrel is full of water, the electric control plate controls the water purifier to stop the water preparation, when the collected weight information of the pressure barrel reaches 1 / 2 to 2 / 3 of the upper limit, the electric control plate judges that the pressure barrel is not full of water, and the electric control plate controls the water purifier to produce water. The method has the advantages that the part of a high-pressure switch is omitted from a machine, and the problems of sanitation, precision, loss, service life and the like of the high-pressure switch per se are avoided. In addition, the judgment is made through the gravity sensing, the precision can reach 0.1g, and the judging precision is high.

Description

technical field [0001] The invention relates to the technical field of water purifiers, household direct drinking machines, and commercial direct drinking machines, in particular to a method for a water purifier to judge that a pressure bucket is full through gravity induction. Background technique [0002] Generally, reverse osmosis water purifiers / direct drinking machines use a high-pressure switch to judge the pressure of the pure water in the pressure barrel. If the pressure exceeds the action value of the high-pressure switch, the high-pressure switch is disconnected, and the machine is judged to be full of water; if the pressure is lower than the high-pressure switch action value, the high pressure switch is closed, and the machine is judged to be in the state of water production. This method of judging whether the machine is full of water / water production through the state of the high-pressure switch has the following disadvantages: [0003] a. The precision of the a...

Problems solved by technology

[0006] The technical problem to be solved by the present invention is to provide a method for a water purifier to judge whether the pressure tank is full of water through gravity sensing. The method uses a gravity sensing device to determine whether the pressure tank is full of water, and avoids judging by a high-voltage switch. The machine removes the The part of the high-voltage switch avoids the problems of hygiene, precision, loss, and life of the high-voltage switch itself. In addition, it is judged by gravity induction, and the accuracy can reach 0.1g, which is high in judgment accuracy.
