Abstract
A cold water circulation type electric water heater belongs to the field of water heaters in household appliance industries and structurally comprises a hot water tank, a cold water pipe communicated with a cold water source, a hot water pipe, a flow regulation valve and a water outlet sprayer. The cold water circulation type electric water heater is characterized by comprising a momentary water storage tank, wherein a liquid level controller is arranged at the bottom in the momentary water storage tank, the bottom of the momentary water storage tank is respectively connected with the cold water pipe and the hot water pipe through a first pipeline and a second pipeline, a third sensor and a fifth control valve are arranged on the first pipeline, a fourth control valve is arranged on the second pipeline, a first control valve is positioned at the upper end of the cold water pipe, a third control valve and a first sensor are positioned at the upper end of the cold water pipe, a second control valve and a second sensor are arranged at the lower end of the hot water pipe, and all control valves and sensor are controlled by a single chip microcomputer. The cold water circulation type electric water heater has the advantages of providing comfortable hot water and avoiding waste of water resources.
Description
Technical field
The invention belongs to water heater field in household electric appliances, be specifically related to a kind of cold water circulation type electric water heater.
Technical background
At present ， family, hotel and office etc. locate to be all provided with can be for washing one's hands, wash one's face, the electric heater of bathing and laundry, mostly its structure is to be stored in boiler by electric hot water, in order to use at any time.But there is one section of no small distance in boiler and user location, need pipe laying to connect, so, when user uses hot water, first by being stored in ducted cold water, drain, just can use hot water, can cause no small waste like this.
Summary of the invention
The object of the invention is to provide a kind of cold water circulation type electric water heater, can effectively overcome the shortcoming that prior art exists.
The present invention realizes like this, as shown in Figure 1, include: the cold water pipe (1) that chamber internal memory is placed with the boiler (8) of hot water, connect with cold water source is, hot-water line (2), the flow control valve (14) that is arranged on hot water pipe junction and the Water outlet spray head (15) of discharging hot water.Its architectural feature is that an of short duration water tank (9) is set, at of short duration water tank (9) inner bottom part, fluid level controller (10) is installed, of short duration water tank (9) bottom is connected with hot-water line (2) with cold water pipe (1) respectively with second pipe (17) by the first pipeline (16).The 3rd inductor (13) and the 5th control valve (7) are installed successively on the first pipeline (16), the 4th control valve (6) is installed on second pipe (17), in the upper end of cold water pipe (1), the first control valve (3) is installed, the 3rd control valve (5) and the first inductor (11) are installed successively before bottom and the first pipeline (16) tie point, the second control valve (4) is located to be provided with near flow control valve (14) in bottom at hot-water line (2), and with second pipe (17) interface point after the second inductor (12) is installed.Above-mentioned each control valve and inductor are all to be controlled by a single-chip microcomputer being arranged in this device.Advantage of the present invention and good effect are: both can provide comfortable hot water, and can avoid again the waste of water.
Accompanying drawing explanation
Fig. 1 is apparatus of the present invention structural representation
Fig. 2 is each control valve working state figure.
Fig. 3 is workflow diagram in system of the present invention.
In figure: the of short duration water tank 10-of 1-cold water pipe 2-hot-water line 3-first control valve 4-the second control valve 5-the 3rd control valve 6-the 4th control valve 7-the 5th control valve 8-boiler (cutaway view) 9-fluid level controller 11-first inductor 12-second inductor 13-the 3rd inductor 14-flow control valve 15-Water outlet spray head 16-the first pipeline 17-second pipe 18-water inlet
The specific embodiment
As shown in Figure 1, when needs are used hot water, can open Water outlet spray head (15), owing to not using for a long time, the hot water in hot-water line (2) has become cold water.Now, the second inductor (12) can predict the temperature that the water temperature in hot-water line (2) sets lower than user, so just this signal is passed to each control valve, the second control valve (4) can be closed, cold water can not be discharged, the 4th control valve (6) is opened, and cold water is flowed in of short duration water tank (9).The second inductor (12) on hot-water line (2) predicts water temperature and reaches user when temperature required, so just this signal is passed to each controller, now, the 4th control valve (6) is closed, the second control valve (4) is opened, hot water can pass through flow control valve (14) and Water outlet spray head (15) is discharged, for user.When the second inductor (12) predicts the temperature value that water temperature in hot-water line (2) sets higher than user, just signal is passed to each control valve, now the 5th control valve (7) is opened, the 3rd control valve (5) is closed, the automatically adjust ratio of hot and cold water of the hot water temperature that the cold water temperature that flow control valve (14) predicts according to the 3rd inductor (13) and the second inductor (12) predict, makes in Water outlet spray head (15) water temperature out reach the requirement that user sets.When in of short duration water storing vessel (9), water level reaches fluid level controller (10) setting value, just this signal is passed to each control valve, so the 5th control valve (7) is closed, the 3rd control valve (5) is opened, now, the water temperature of the hot-water line that the water temperature of the cold water pipe that flow control valve (14) predicts according to the first inductor (11) and the second inductor (12) predict regulates hot and cold water ratio automatically, reaches the requirement that user sets.
