Above-mentioned leaving water temperature adjustment process is completed automatically by control module, and without the need to user's manual adjustments, and governing speed is very fast, can meet user's actual need.And this thermostat can seamlessly be connected with other hot water facility, without the need to controlling hot water facility, but carry out adjusting water outlet temperature by the second water inlet temperature of the delivery port water temperature of thermostatic assembly, the first water inlet temperature of thermostatic assembly and the thermostatic assembly that detect, to ensure effluent temperature constancy, instant-heating.
According to an embodiment of the present utility model, the control method of above-mentioned thermostat, also detect the delivery port discharge of thermostatic assembly, wherein, when delivery port discharge is greater than the first preset flow and delivery port water temperature is greater than the first temperature threshold, or when delivery port discharge is greater than the first preset flow and delivery port water temperature is less than the second temperature threshold, the delivery port also controlling thermostatic assembly is closed, wherein, the first temperature threshold is greater than the second temperature threshold.
Specifically, as shown in Figure 2, when user open use water end (W.E.) time, delivery port water temperature and the delivery port discharge of thermostatic assembly is detected by first detection module, when delivery port discharge is greater than the first preset flow and delivery port water temperature is greater than the first temperature threshold, the delivery port that control module controls thermostatic assembly is closed, and avoids exporting a large amount of high-temperature-hot-water and scalds user; When delivery port discharge is greater than the first preset flow and delivery port water temperature is less than the second temperature threshold, the delivery port that control module controls thermostatic assembly is closed, avoid exporting a large amount of low-temperature cold water frostbite user, thus ensure that the leaving water temperature of thermostat is suitable, both user can not be scalded, also can not frostbite user, ensure safe water outlet.
According to an embodiment of the present utility model, the control method of above-mentioned thermostat, also comprises: when the water inlet water temperature of water storage device is less than the delivery port water temperature of thermostatic assembly, control heater is opened; When the water inlet water temperature of water storage device is more than or equal to the delivery port water temperature of thermostatic assembly, control heater is closed.
Specifically, heater is provided with in water storage device, the water inlet water temperature of water storage device is detected in real time by the second detection module, when the water inlet water temperature of water storage device is less than the delivery port water temperature of thermostatic assembly, the heater that control module controls in water storage device is opened, enter the pipeline cold water temperature of water storage device to improve, even if thus ensure have cold water also can not affect the leaving water temperature of thermostat between thermostat and hot water facility; When the water inlet water temperature of water storage device is more than or equal to the delivery port water temperature of thermostatic assembly, control module control heater is closed.
According to an embodiment of the present utility model, the control method of above-mentioned thermostat, also detect the water inlet discharge of water storage device, wherein, when the water inlet discharge of water storage device is less than first flow threshold value, heighten the water inlet ratio of the first water inlet of thermostatic assembly, until the water inlet discharge of water storage device is more than or equal to first flow threshold value.
Wherein, first flow threshold value can be 3L/min.
Specifically, when the external hot water facility of thermostat is gas heater, control module carrys out the opening and closing of control heater except the water inlet water temperature of water storage device detected according to the second detection module, also regulate according to the water inlet ratio of water inlet discharge to the first water inlet of thermostatic assembly of the water storage device of the second detection module detection, to ensure that gas heater can not stop working.
Namely say, when the water inlet discharge of water storage device is less than first flow threshold value as 3L/min, control module heightens the water inlet ratio of the first water inlet of thermostatic assembly, until water inlet discharge is more than or equal to first flow threshold value 3L/min, to ensure that gas heater can not be little and flame-out because of discharge.In the process, due to gas heater not starting ignition, the water temperature in water storage device reduces, and now control module can regulate the water inlet ratio of the second water inlet according to leaving water temperature correspondence, to ensure that thermostat leaving water temperature is met consumers' demand.
In addition, in the control method of above-mentioned thermostat, the leaving water temperature of one or more receptions users setting in the communication modes such as radio frequency, WIFI, bluetooth and Zigbee and the operational factor of thermostat can also be passed through.And, when the multiple thermostat of user installation, user can set different leaving water temperatures by intelligent terminal to each thermostat, and can communication mutually between each thermostat, thus together respective operational factor is fed back to intelligent terminal, realize remote monitoring.
According to the control method of the thermostat of the utility model embodiment, first the water inlet water temperature of water storage device is detected, then the temperature gap between the leaving water temperature of user's setting and the water inlet water temperature of water storage device is obtained, and temperature gap is judged, if water inlet water temperature is less than the leaving water temperature of user's setting and temperature gap is greater than default temperature threshold, the first end then controlling triple valve is communicated with the 3rd end, otherwise the second end controlling triple valve is communicated with the 3rd end.Therefore, the control method of the thermostat of the utility model embodiment, by solving pipeline cold water problem to the control of triple valve, ensures that the water temperature in water storage device does not decline substantially, thus ensures effluent temperature constancy, meet consumers' demand.Meanwhile, when being cold water in pipeline, only have fraction cold water to enter water storage device, the power of the heater therefore in water storage device can be smaller, thus without the need to laying power line specially to the heater in water storage device.
