Description
Technical field
The utility model belongs to household daily necessities field, relates to bathing apparatus, is specifically related to a kind of bathing cold water retracting device.
Background technology
Along with social economy's develop rapidly, the wealth that we create grows with each passing day, and meanwhile natural resources is striking alarm bell to us, and we waste a large amount of resources while creation material wealth, and China is the serious country of a drought and water shortage.Though freshwater resources total amount accounts for 6% of global water resources, only have 2200 cubic metres per capita, be only 1/4 of world average level, 1/5 of the U.S., ranking the 121st in the world, is one of 13 countries that water resource is the poorest per capita in the whole world.In addition waste water during family, hotel's bathing now very serious.How when bathing, the waste of water resource to be dropped to the minimum target being us and pursuing now.In present family, hotel, water heater bathing apparatus is generally housed, when people are in bathing, by-pass cock carries out bathing when making temperature reach the temperature of suitable bathing, the needs regular hour is applicable to water temperature from opening bathing switch, now we are quiet wastes a lot of cold water, once seem few, but take care of the pence.
Utility model content
The purpose of this utility model is to provide a kind of bathing cold water retracting device, and to overcome the defect that above-mentioned prior art exists, the utility model effectively can reclaim and can not to be used for the cold water of bathing when just opening bathing switch, using water wisely.
For achieving the above object, the utility model adopts following technical scheme:
A kind of bathing cold water retracting device, comprise water heater water tank, the bottom of water heater water tank is connected with the hot-water line for going out hot water and the cold water pipe for entering cold water, be connected with for the mixing tube by cold water and hot water mixing between hot-water line and cold water pipe, mixing tube is connected with gondola water faucet by flexible pipe, the junction of hot-water line and mixing tube is provided with temperature sensor switch, is connected with return duct between temperature sensor switch and water heater water tank.
Further, when pre-set threshold value lower than temperature sensor switch of the leaving water temperature of hot-water line, hot-water line is communicated with return duct; When pre-set threshold value higher than temperature sensor switch of the leaving water temperature of hot-water line, hot-water line is communicated with mixing tube.
Further, the junction of mixing tube and flexible pipe is provided with Mixed water valve.
Further, cold water pipe is provided with the water intaking valve that can control to enter mixing tube cool water quantity.
Further, water heater water tank is cylindrical.
Further, flexible pipe is rubber tube.
Compared with prior art, the utility model has following useful technique effect:
The utility model is the return duct adding a temperature sensor switch and be connected with temperature sensor switch before traditional bathing apparatus Mixed water valve, when the preceding pipeline internal memory due to bathing has water that last time, bathing did not drain to cause current bathing, even if Mixed water valve is opened to hot water place by us, bathing last time that remains flowed out is stranded in cold water in pipeline, the mercilessness of water resource will be caused to waste if drained, if but before Mixed water valve, add a temperature sensor switch, when we need hot water, the cold water had in hot-water line flows into temperature sensor switch, control to be used further to bathing after it still reclaims heating for bathing by temperature sensor switch, save water resource greatly.
Further, when bathing just starts, the cold water do not drained when leaving bathing last time in hot-water line, when cold water flow to temperature sensor switch place, do not reach established temperature threshold values then to be heated to water heater water tank by return line flow, if reach established temperature threshold values, the hot water in hot-water line then flows into mixing tube, with the cold water mix of cold water pipe, while easy to use, save water source.
Accompanying drawing explanation
Fig. 1 is overall structure schematic diagram of the present utility model;
Fig. 2 is the temperature control principle drawing of the utility model temperature sensor switch.
Wherein, 1-water heater water tank, 2-hot-water line, 3-temperature sensor switch, 4-Mixed water valve, 5-water intaking valve, 6-return duct, 7-cold water pipe, 8-gondola water faucet, 9-mixing tube, 10-flexible pipe.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail:
See Fig. 1, a kind of bathing cold water retracting device, comprise columniform water heater water tank 1, the bottom of water heater water tank 1 is connected with the hot-water line 2 for going out hot water and the cold water pipe 7 for entering cold water, be connected with for the mixing tube 9 by cold water and hot water mixing between hot-water line 2 and cold water pipe 7, cold water pipe 7 is provided with the water intaking valve 5 that can control to enter mixing tube 9 cool water quantity, mixing tube 9 is connected with gondola water faucet 8 by flexible pipe 10, flexible pipe 10 is rubber tube, mixing tube 9 is provided with Mixed water valve 4 with the junction of flexible pipe 10, the junction of hot-water line 2 and mixing tube 9 is provided with temperature sensor switch 3, return duct 6 is connected with between temperature sensor switch 3 and water heater water tank 1, when pre-set threshold value lower than temperature sensor switch 3 of the leaving water temperature of hot-water line 2, hot-water line 2 is communicated with return duct 6, when pre-set threshold value higher than temperature sensor switch 3 of the leaving water temperature of hot-water line 2, hot-water line 2 is communicated with mixing tube 9.
See Fig. 2, temperature sensor switch 3 of the present utility model adopts Resistance Temperature controller temperature detect switch (TDS) (single-pole double-throw switch (SPDT)).Wherein, thermal resistance temperature sensor Rt principle utilizes temperature sensitive resister that variations in temperature to be measured is changed into current signal to export.When water temperature is lower, temperature detect switch (TDS) internal resistance is larger, the cold water flowed out from hot-water line 2 flows back to water heater water tank 1 through return duct 6, along with the continuous rising of water temperature in hot-water line 2, temperature detect switch (TDS) internal resistance is constantly reduced, when temperature reaches the temperature of setting, hot water flows out in mixing tube 9.
Below operating process of the present utility model is described in detail:
The utility model is the return duct 6 adding a temperature sensor switch 3 and be connected with temperature sensor switch 3 before traditional bathing apparatus Mixed water valve, when the preceding pipeline internal memory due to bathing has water that last time, bathing did not drain to cause current bathing, even if Mixed water valve 4 is opened to hot water place by us, bathing last time that remains flowed out is stranded in cold water in pipeline, the mercilessness of water resource will be caused to waste if drained, if but before Mixed water valve 4, add a temperature sensor switch 3, when we need hot water, the cold water had in hot-water line 2 flows into temperature sensor switch 3, temperature sensor switch 3 arranges a threshold temperature, as 25 degree, then when temperature is lower than 25 degree, hot-water line 2 is communicated with return duct 6, water flows back to water heater water tank 1 by return duct 6, when temperature is higher than 25 degree, hot-water line 2 is communicated with mixing tube 9, the cold water of discharging when we need hot water like this would not by the waste of mercilessness, the waste of effective prevention water resource.
Mixed water valve 4 is opened during bathing, be adjusted to hot water, the cold water do not drained when now leaving bathing last time in hot-water line 2, when cold water flow to temperature sensor switch 3 place, do not reach established temperature threshold values then to flow to water heater water tank 1 by return duct 6 and heat, if reach established temperature threshold values, the hot water in hot-water line 2 then flows into mixing tube 9, with the cold water mix of cold water pipe 7, the water that Mixed water valve 4 opens rear suitable bathing temperature is sprayed by gondola water faucet 8.
