Description
Technical Field
The invention relates to a water temperature regulating device for nursing and cleaning, in particular to a water temperature regulating device.
Background
At present, China is still a developing country with extreme water shortage, but economic construction and environmental protection saving are not ignored, and the development of both is becoming more and more important. According to investigation, the nursing and cleaning of the inpatient need proper warm water, a water faucet needs to be opened firstly in nursing to enable water flow for a moment, cleaning is carried out after the outlet water temperature is proper, when the water temperature is high or low, hot water or cold water flows for a moment after a switch is adjusted, and water resources in the waiting process are greatly wasted. Firstly, the waste of water resources is not good for economic construction and environmental protection saving, and secondly, the comfort of nursing and cleaning is greatly reduced. The research on the intelligent temperature control faucet in China has made great progress, and part of the research is put into use, so that great convenience is provided for nursing, cleaning and various water use. Based on PT100 thermistor, North China electric university has designed control by temperature change tap, and the temperature measurement contact is placed in the delivery pipe, measures the temperature of treating the delivery pipe. If the measured temperature is lower than the preset expected temperature, the single chip microcomputer judges the temperature to be 'cold water' after receiving the signal, at the moment, the electromagnetic valve opens the temperature control switch, and the judged 'cold water' flows back to the water storage device; and on the contrary, the water heater is judged to be the 'hot water' required by people, the electromagnetic valve closes the temperature control switch, and the 'hot water' flows out of the faucet. The Monte fluid equipment Limited company designs a pipe wall type thermostatic valve, a sensor for sensing water temperature is arranged at a water outlet of a thermostatic water mixing valve, a valve core is pushed by sensing the water temperature, a cold water inlet and a hot water inlet are opened or blocked, and the water inlet proportion of the cold water and the hot water is adjusted; when the outlet water temperature is set through the temperature knob, when the inlet water temperature and the inlet water pressure of the cold water and the hot water are changed, the sensor senses the water temperature and drives the valve core to move, the inlet water proportion of the cold water and the hot water is changed along with the change of the inlet water temperature, and therefore the outlet water temperature is kept stable.
The traditional temperature control device has the following defects: (1) the sizes of water inlets at two ends are changed through the rotation of the valve core, so that the sizes of the cold and hot water inlets are simply controlled, and the mixing ratio of hot water and cold water is not well controlled; (2) the hot water and cold water have different water inlet pressures, and the pressures of the two water inlets are in a constant fluctuation state, so that the mixing ratio of the hot water and the cold water is constantly changed, and the water temperature is easy to be suddenly increased or decreased; (3) when the water inlet size at one end of the water mixing valve is changed by adjusting the water mixing valve, due to inertia and viscosity of water, the water inflow is unchanged in a short time when the water pressure is correspondingly increased or decreased, so that the water temperature is not changed, and a period of time is required to wait after each adjustment of the switch.
