Water purifier and method for determining residual life value of water purification filter element in water purifier

Abstract

The invention provides a water purifier and a method for determining a residual life value of a water purification filter element in the water purifier. The water purifier comprises a water purification filter element, a pressure barrel, a high voltage switch, a stabilized pressure pump and a controller, wherein the water purification filter element is connected with a raw water inlet and used for purifying the raw water entering from the raw water inlet; the pressure barrel is connected with the water purification filter element and used for storing pure water purified by the water purification filter element; the stabilized pressure pump is arranged between the water purification filter element and the pressure barrel and used for stabilizing the water pressure of a water path; and the controller is connected with the stabilized pressure pump and used for controlling the operation state of the water purifier, counting the accumulated operation time of the stabilized pressure pump and adjusting the residual life value of the water purification filter element according to the accumulated operation time. By adopting the water purifier, the technical problem in the prior art that the cost for determining the life value of the water purification filter element by virtue of a pulse counter is excessively high can be solved, and a technical effect for effectively decreasing the cost of the water purifier can be realized.

Description

technical field [0001] The invention relates to the technical field of equipment control, in particular to a water purifier and a method for determining the remaining life value of a water purification filter element in the water purifier. Background technique [0002] At present, the life of the water purification filter element in the water purifier is generally calculated by a pulse counter (or called a flow meter), specifically, the number of pulses recorded by the pulse counter is divided by the number of pulses corresponding to 1L of water to obtain When the water consumption used by the water purifier reaches the preset life value of the water purification filter element, an alarm will prompt the user to replace the water purification filter element. [0003] However, the cost of the flow meter is high, and the space of the water purifier is limited. Therefore, the cost of equipment required to calculate the life value of the water purifying filter element using a pul...
