Abstract
A cold water circulating type electric water heater belongs to the field of water heaters in the household electrical appliance industry and is structurally characterized by comprising a hot water tank, a cold water pipe communicated with a cold water source, a hot water pipe, a flow control valve and a water outlet nozzle. The cold water circulating type electric water heater is characterized in that a temporary water storage tank is arranged, a liquid level controller is mounted in the internal bottom of the temporary water storage tank, the bottom of the temporary water storage tank is respectively connected with the cold water pipe and the hot water pipe by a first pipeline and a second pipeline, a third inductor and a fifth control valve are mounted on the first pipeline, a fourth control valve is mounted on the second pipeline, a first control valve is mounted at the upper end of the cold water pipe, a third control valve and a first inductor are mounted at the lower end of the cold water pipe, a second control valve and a second inductor are mounted at the lower end of the hot water pipe, and the control valves and the inductors are all controlled by one singlechip. The cold water circulating type electric water heater has the advantages that comfortable hot water can be provided and the waste of water resource can be avoided.
Description
Technical field
The utility model belongs to water heater field in the household electric appliances, is specifically related to the circulating electric heater of a kind of cold water.
Background technology
At present, locate all to be equipped with in family, hotel and office etc. can supply to wash one's hands, wash one's face, the electric heater of bathing and laundry usefulness, mostly its structure is to be stored in the boiler through electric hot water, in order to using at any time.But there is one section no small distance in boiler and user location, need pipe laying to connect, and so, when the user uses hot water, drain being stored in ducted cold water earlier, just can use hot water, can cause no small waste like this.
Summary of the invention
The utility model purpose provides the circulating electric heater of a kind of cold water, can overcome the shortcoming that prior art exists effectively.
The utility model is to realize like this; As shown in Figure 1, include: cold water pipe (1), the hot-water line (2) of discharging hot water that the chamber internal memory is placed with the boiler (8) of hot water, connect with cold water source, be installed in the flow control valve (14) of hot water pipe junction and go out sprinkler head (15).Its architectural feature is that an of short duration water tank (9) is set, and at of short duration water tank (9) inner bottom part fluid level controller (10) is installed, and of short duration water tank (9) bottom is connected with hot-water line (2) with cold water pipe (1) respectively with second pipeline (17) through first pipeline (16).The 3rd inductor (13) and the 5th control valve (7) are installed on first pipeline (16) successively; The 4th control valve (6) is installed on second pipeline (17); In the upper end of cold water pipe (1) first control valve (3) is installed; Front at bottom and first pipeline (16) tie point is equipped with the 3rd control valve (5) and first inductor (11) successively; Second control valve (4) is located to be equipped with near flow control valve (14) in bottom at hot-water line (2), and with second pipeline (17) interface point after second inductor (12) is installed.Above-mentioned each control valve and inductor all are to be controlled by a single-chip microcomputer that is installed in this device.The utility model advantage and good effect are: both comfortable hot water can be provided, and can avoid the waste of water again.

Among the figure: the of short duration water tank 10-of the 1-cold water pipe 2-hot-water line 3-first control valve 4-second control valve 5-the 3rd control valve 6-the 4th control valve 7-the 5th control valve 8-boiler (cutaway view) the 9-fluid level controller 11-first inductor 12-second inductor 13-the 3rd inductor 14-flow control valve 15-goes out the sprinkler head 16-first pipeline 17-second pipeline 18-water inlet
The specific embodiment
As shown in Figure 1, when needs are used hot water, can open out sprinkler head (15), owing to do not use for a long time, the hot water in the hot-water line (2) has become cold water.At this moment, the water temperature that second inductor (12) can predict in the hot-water line (2) is lower than the temperature that the user sets, so just pass to each control valve to this signal; Second control valve (4) can be closed; Cold water can not be discharged, and the 4th control valve (6) is opened, and cold water is flowed in the of short duration water tank (9).When predicting water temperature, second inductor (12) on the hot-water line (2) reaches the user when temperature required; So just pass to each controller to this signal; At this moment, the 4th control valve (6) is closed, and second control valve (4) is opened; Hot water can and go out sprinkler head (15) through flow control valve (14) discharges, and supplies the user to use.When second inductor (12) predicts water temperature in the hot-water line (2) and is higher than the temperature value that the user sets; Just pass to each control valve to signal; The 5th control valve this moment (7) is opened; The 3rd control valve (5) is closed, and the automatically adjust ratio of hot and cold water of the hot water temperature that cold water temperature that flow control valve (14) predicts according to the 3rd inductor (13) and second inductor (12) predict is used the water temperature of coming out in the sprinkler head (15) and reached the requirement that the user sets.When water level in the of short duration water storing vessel (9) reaches fluid level controller (10) setting value; Just pass to each control valve to this signal; So the 5th control valve (7) is closed, the 3rd control valve (5) is opened, at this moment; The water temperature of the cold water pipe that flow control valve (14) predicts according to first inductor (11) and the water temperature of the hot-water line that second inductor (12) predicts are regulated the hot and cold water ratio automatically, reach the requirement that the user sets.
