Embodiment 1

[0033] This embodiment proposes a constant temperature and constant outflow water control method. This control method is based on the fact that the cold and hot water have an adjustment mechanism respectively, and can independently adjust the water output of the cold and hot water, such as figure 1 As shown, the constant temperature cross-flow water control method comprises the following steps:

[0034] S1. Collect the set temperature To of the water outlet and the set flow rate Fo of the water outlet;

[0035] Among them, the set temperature To of the water outlet and the set flow rate Fo of the water outlet can be directly set by the user through the buttons or the remote control, and are collected as setting parameters. The step of setting the flow Fo, if the user has not set it, the set water temperature To and the set flow Fo of the water in step S1 adopt the default value or the set value of the previous use. Therefore, after each setting by the user , also has a memory...

Embodiment 2

[0047] Based on the constant temperature and cross flow control method in Embodiment 1, this embodiment proposes a constant temperature and constant flow valve, such as figure 2 , image 3 As shown, the constant temperature and constant flow valve includes a valve body 10, a cold water tank 11, a hot water tank 12, a mixing tank 13, and a control unit 14 arranged in the valve body 10, and one end of the hot water tank 12 is used to communicate with a hot water pipe. One end communicates with the water mixing tank 13 through the first communication port 15, the first communication port 15 is provided with a hot water regulating mechanism 16 capable of adjusting the opening of the first communication port 15, one end of the cold water tank 11 is used to communicate with the cold water pipe, and in addition One end communicates with the water mixing tank 13 through the second communication port 17, the second communication port 17 is provided with a cold water adjustment mechani...

Abstract

The invention discloses a constant-temperature constant-flow water outlet control method and a constant-temperature constant-flow valve. The constant-temperature constant-flow water outlet control method comprises the following steps that (1) the water outlet set temperature To and the water outlet set flow Fo are collected; (2) the cold water temperature Tic and the hot water temperature Tih aredetected; (3) the proportion of cold water and hot water is calculated according to the water outlet set temperature To, the cold water temperature Tic and the hot water temperature Tih; (4) the coldwater flow FL and the hot water flow FR are calculated according to the proportion of the cold water and the hot water and the water outlet set flow Fo correspondingly; and (5) the opening degree of acold water adjusting mechanism and the opening degree of a hot water adjusting mechanism are synchronously adjusted, so that the requirements of the proportion of the cold water and the hot water, the cold water flow FL and the hot water flow FR are met. According to the constant-temperature and constant-flow water outlet control method, the cold and hot water temperature, the water inlet and outlet temperature, the water outlet flow are used as the detection variable for realizing control, accurate detection is carried out on the detection variable, moreover, the proportion of the cold waterand the hot water and the flow of the cold water and the hot water are accurately calculated, then the opening degree of the cold water adjusting mechanism and the opening degree of the hot water adjusting mechanism are adjusted, so that the control is more accurate, and the bathing comfort is improved.

Description

technical field [0001] The invention relates to the technical field of constant temperature and constant flow control, in particular to a constant temperature and constant flow water control method and a constant temperature and constant flow valve. Background technique [0002] There are three main structures of water mixing valve to achieve constant temperature water outlet control: ordinary water mixing valve can adjust the water outlet temperature by manually adjusting the ratio of hot water inlet and cold water inlet, but this kind of water mixing valve is affected by water temperature and flow rate and cannot be kept at constant temperature. And every time it needs to be adjusted several times by people to reach the appropriate temperature; the ordinary thermostatic mixing valve can set the water temperature manually and mechanically, and the mixing valve can realize the constant temperature of the water outlet, but this constant temperature cannot be accurate, it is ba...
