The water circulation device has the advantage that once a hot water tap switch is turned on, hot water flows out immediately.
Description
Technical field
The invention belongs to technical field of electronic devices, relate to a kind of temperature-controllable gas heater water circle device.
Background technology
In life, have such phenomenon: we use gas heater time, because hydraulic pressure is too low, cold water flow backwards, out be not hot water; Winter approached, opens heater switch, sometimes will wait one or two minute hot water could out.According to investigations, to initial cold water of releasing, family about over half pours off arbitrarily, and this not only causes the waste of water resource, and is brought inconvenience with the people of hot water.
Add up discovery according to investigations, the popularity rate of China's urban family water heater product is basically stable at about 70%, and in water heater user, gas heater accounts for total user's about 57%.Each family generally at least uses twice water heater for each person every day, rough estimation: calculate according to general three-person household, everyone uses water heater to begin about to release 6 liters, cold water when putting at every turn, cold water 6 × 3 × 2=36 (liter) within one day, will be released, learn according to online inquiry, the current nearly gas heater user more than 3,000 ten thousand of China, within one day, about release 36 × 3,000 ten thousand=1,080,000,000 liters, cold water, within 1 year, about release cold water 108000 × 36,5/2,=19,710,000 ten thousand liters, (note: had the higher calculation of the temperature requirement of half a year to water by a year).Be 600,000 liters of calculation by the water consumption in people all one's life, within 1 year, be equivalent to 328500 people water consumption throughout one's life due to the water resource waste using water heater to cause.We calculate again: the price of one ton of water is about 1.1 yuan, the price of 197100000000 premium on currency is 19710000 × 1.1 ÷ 1000=216810000 units, be 1000 yuan of calculating according to the subsidy out-of-school children expense of a year, the money can be subsidized 21680000 ÷ 1000=21680 (individual) out-of-school children and be returned to campus.Thus, transformation is carried out to gas heater necessary.
The reason one causing gas heater to go out cold water is that hydraulic pressure is too low, cold water flow backwards, out be not hot water; Two is that user house is large, and family has only installed a gas heater, oversize to the distance of water heater outlet with the tap of hot water, and timely the cold water of water heater will be added to hot water needs certain hour.For cold water problem when solving and put at the beginning of gas heater, first will after using last time, remain in water in pipe by piping loop, release again after water heater heating.
Summary of the invention
The object of the present invention is to provide a kind of temperature-controllable gas heater water circle device, solve current pot-type boiler start flow out be cold water, the problem of waste water resource.
The technical solution adopted in the present invention is system water path: the entrance of tap water inlets connected electromagnetic valve, the outlet of magnetic valve connects the cold water inlet of gas heater and one end of booster pump respectively, the other end of booster pump connects the hot water outlet of gas heater, and the cold water inlet of booster pump, gas heater and the hot water outlet of gas heater form a path by pipeline.
Circuit system: booster pump connects electromagnetic relay, electromagnetic relay connects MCU single-chip microcomputer, and MCU single-chip microcomputer connects Hall switch, temperature measurement device and magnetic valve respectively.
Hall switch is arranged on the tube connector between the hot water outlet of gas heater and booster pump, the break-make of control connection pipe, and temperature measurement device is arranged on the tube connector between the hot water outlet of gas heater and booster pump, carries out the detection of hot water temperature.
The invention has the beneficial effects as follows the gas heater water circle device providing temperature-controllable.As long as this device is arranged on the inlet tube and outlet tube of gas heater, just can realize one and open hot water tap switch, out first is hot water.
Accompanying drawing explanation
Fig. 1 is temperature-controllable gas heater water circle device structural representation of the present invention.
In figure, 1. magnetic valve, the 2. cold water inlet of gas heater, 3. booster pump, the 4. hot water outlet of gas heater, 5. electromagnetic relay, 6.MCU single-chip microcomputer, 7. Hall switch, 8. temperature measurement device.
Detailed description of the invention
Below in conjunction with detailed description of the invention, the present invention is described in detail.
The present invention as shown in Figure 1, system water path: the entrance of tap water inlets connected electromagnetic valve 1, the outlet of magnetic valve 1 connects the cold water inlet 2 of gas heater and one end of booster pump 3 respectively, the other end of booster pump 3 connects the hot water outlet 4 of gas heater, and the cold water inlet 2 of booster pump 3, gas heater and the hot water outlet 4 of gas heater form a path by pipeline.
Circuit system: booster pump 3 connects electromagnetic relay 5, electromagnetic relay 5 connects MCU single-chip microcomputer 6, MCU single-chip microcomputer 6 and connects Hall switch 7, temperature measurement device 8 and magnetic valve 1 respectively.
Hall switch 7 is arranged on the tube connector between the hot water outlet 4 of gas heater and booster pump 3, and control the break-make of water, temperature measurement device 8 is arranged on the tube connector between the hot water outlet 4 of gas heater and booster pump 3, carries out the detection of hot water temperature; Native system also comprises power module, and the battery of available routine or external power supply are to system power supply.
Present system, set at MCU single-chip microcomputer 6 water temperature that we will commonly use, temperature measurement device 8 detects water temperature automatically.When the temperature that water temperature sets lower than us, open heater switch, Hall switch 7 detects current, magnetic valve 1 closes water pipe path, and the booster pump 3 that electromagnetic relay 5 controls to be connected works, because magnetic valve 1 has cut off current, affect without ambient pressure, booster pump 3, at this moment to whole circulating line supercharging, promotes water flow in circulating line, and water heater is to the water heating in circulating line.When the temperature that water temp. heating sets to us, MCU single-chip microcomputer 6 disconnecting circuit, booster pump 3 stops supercharging, and extraneous water enters pipeline, and at this moment hot water will flow out.After water heater normally works, extraneous cold water enters with regard to normal heating after gas heater, and the hot water temperature of setting is flowed out in circulation.
Present system can control gas heater output water temperature, solves gas heater when using to winter, needs to wait the preceding paragraph time just to go out hot water problem.Avoid the waste of water resource, this device ensure that people are when using gas heater, and out first is exactly hot water, avoids water resource waste, brings more convenient.This device can control water temperature, can reach the suitable water temperature required for people.This device allows booster pump consumption in operation electric energy when being only circulating water, other time do not consume electric energy, saved electric energy.
The above is only to better embodiment of the present invention, not any pro forma restriction is done to the present invention, every any simple modification done above embodiment according to technical spirit of the present invention, equivalent variations and modification, all belong in the scope of technical solution of the present invention.
