Description

Electric water heater

Technical Field

The utility model relates to a life electrical apparatus articles for use field, specific electric water heater that says so.

Background

The electric water heater is a water heater which heats by taking electricity as energy. Is one of three water heaters which are parallel to a gas water heater and a solar water heater. The electric water heater can be divided into a water storage type (also called a positive displacement type or a heat storage type), an instant heating type and an instant heating type (also called a semi-water storage type) according to the heating power.

Although the volume of the common quick-heating electric water heater is almost the same as that of the double-mode electric water heater, the internal structure of the common quick-heating electric water heater is greatly different from that of the double-mode electric water heater, the ratio of the quick-heating electric water heater to the water storage type electric water heater is only smaller in volume and higher in power, so that the heating speed is higher than that of the water storage type electric water heater, but the quick-heating electric water heater can not achieve instant heating in spring and autumn and also needs preheating, namely waiting is needed, and the double-mode electric water heater can use an instant heating mode in spring, summer and autumn.

The existing electric water heater can reach the bath temperature only by manually adjusting the cold/hot water proportion of the water mixing valve when in bath, the water outlet temperature can only feel whether to be suitable for the bath temperature by the body, the use experience effect is not good enough, and when cold water or hot water is lost, scalding or cold shock is easy to occur, so that some potential safety hazards also exist.

The utility model provides a technical scheme that its technical problem adopted is:

the utility model discloses an electric water heater, which comprises a shell, wherein a water inlet liner and a water outlet liner communicated with the water inlet liner are arranged in the shell, one end of the water inlet liner is connected with a cold water inlet and a sewage outlet, and a water inlet liner heating pipe is arranged in the water inlet liner;

one end of the water outlet liner is connected with a thermostatic valve, the water outlet liner is connected with a hot water outlet through the thermostatic valve, and a heating pipe is arranged in the water outlet liner.

Preferably, the wall of the water inlet inner container and the wall of the water outlet inner container are both provided with a waterproof heat-insulating layer.

Preferably, the heating pipe is a spiral energy-gathering ring heating pipe.

Preferably, a valve and a motor for controlling the valve to open and close are arranged in the thermostatic valve, the motor is connected with a controller, a temperature sensor for measuring the temperature of mixed water is arranged at a hot water outlet of the thermostatic valve, and the temperature sensor is mutually associated with the controller.

Preferably, the motor is a stepping motor.

Further, the controller is associated with a liquid crystal display panel.

The utility model has the advantages that: simple structure, convenient to use can go out water and automatic adjustment with the constant temperature to can look over cold/hot water ratio situation, not worry that the condition of neglecting cold neglects hot appears.

In the figure: 1. theshell 2, thewater inlet liner 3, thewater outlet liner 4, thecold water inlet 5, the sewage outlet 6, the water inletliner heating pipe 7, thethermostatic valve 8, thehot water outlet 9, theheating pipe 10, thewaterproof insulating layer 11, thevalve 12, themotor 13, the controller 14, thetemperature sensor 15 and the liquid crystal display panel.

Detailed Description

In order to make the technical problem, technical scheme and beneficial effect that the utility model solved more clearly understand, it is right below to combine the attached drawing and embodiment the utility model discloses do further explanation. It should be understood that the embodiments described herein are merely for the purpose of illustrating the invention and are not intended to limit the invention.

As shown in fig. 1-2, the electric water heater of the present invention comprises acasing 1, awater inlet liner 2 and awater outlet liner 3 communicated with thewater inlet liner 2 are arranged in thecasing 1, one end of thewater inlet liner 2 is connected with acold water inlet 4 and asewage outlet 5, and a water inlet liner heating pipe 6 is arranged in thewater inlet liner 2;

one end of the water outletinner container 3 is connected with athermostatic valve 7, the water outletinner container 3 is connected with ahot water outlet 8 through thethermostatic valve 7, and aheating pipe 9 is arranged in the water outletinner container 3. Through theinner bag 2 of intaking and the 3 structures of play water inner bag that communicate with theinner bag 2 of intaking, can let cold water preheat in theinner bag 2 of intaking, consequently, cold, hot water can more homogeneous mixing, andthermostatic valve 7 also can adopt conventional electron thermostatic valve.

In order to provide a heat preservation effect and better save energy, the cavity walls of thewater inlet liner 2 and thewater outlet liner 3 are both provided with a waterproofheat preservation layer 10.

Theheating pipe 9 is a spiral energy-gathering ring heating pipe, and because the contact area of the spiral energy-gathering ring heating pipe and water is relatively large, the heating efficiency is high, and the heating effect is good.

In order to realize constant-temperature water outlet and automatic adjustment and check the cold/hot water ratio, avalve 11 and amotor 12 for controlling the opening and closing of thevalve 11 are arranged in the thermostatic valve, themotor 12 is connected with acontroller 13, ahot water outlet 8 of thethermostatic valve 7 is provided with a temperature sensor 14 for measuring the temperature of mixed water, and the temperature sensor 14 is mutually associated with thecontroller 13.

When bathing, water flows out from the thermostatic valve 7 (or the electronic thermostatic valve), according to the set temperature of the water heater, the angle of the valve core can be automatically adjusted by rotating the valve core by the motor 12 (the stepping motor), constant-temperature water outlet is realized by carrying out cold/hot water proportion distribution, and the condition that cold and hot appear suddenly is well solved.

In order to allow the user to visually check the data of the cold/hot water ratio and the temperature, thecontroller 13 is associated with a liquidcrystal display panel 15, and the data is displayed through the liquidcrystal display panel 15.

As an embodiment, the liquidcrystal display panel 15 is provided with 4 keys, including 1 power key for on/off, 1 mode key for selecting a winter/spring/autumn/summer heating mode, 1 plus key for adjusting the temperature rise of the outlet water temperature, and 1 minus key for adjusting the temperature drop of the outlet water temperature, and the function is realized by a circuit board provided with a controller.

The foregoing is considered as illustrative of the preferred embodiments only, and it is understood that various changes, substitutions and alterations can be made herein without departing from the spirit and scope of the invention as defined by the appended claims.
