In a first embodiment, as shown in fig. 1 to 3, the present embodiment provides an electric water heater, including:
the water tank 1 is provided with a water inlet pipe 11 and a water outlet pipe 12;
a tee 2, the tee 2 configured with a first orifice (not labeled), a second orifice (not labeled), and a third orifice (not labeled);
the thermostatic valve 3 is provided with a first inlet 31, a second inlet 32 and a mixed water outlet 33, and the thermostatic valve 3 is connected to the water outlet pipe 12 through the first inlet 31;
the first pipe orifice is communicated with the water inlet pipe 11, the first inlet 31 is communicated with the water outlet pipe 12, and the second pipe orifice is communicated with the second inlet 32.
In the actual use process, the electric water heater is directly installed at a user home through the hanging rack, is connected with a water supply pipe at the user home through the three-way pipe 2, and is connected with a water using terminal at the user home through the thermostatic valve 3, wherein the water using terminal can be a shower head or a hot water faucet and other conventional water outlet components. Cold water supplied from a water supply pipe is introduced into the water tank 1 through a three-way pipe 2, and an electric heating part (e.g., an electric heating rod) is provided in the water tank 1 to heat the water in the water tank 1.
In general, a user sets the heating water temperature of the electric heater to be more than 50 degrees, so as to meet the requirement of the user on using hot water. When the user actually uses hot water, the water temperature needs to be about 38 ℃. Thus, when the user opens the water usage terminal, then the water supply pipe supplies cold water, a portion of which enters the water tank 1 to drive the hot water in the water tank 1 out of the book outlet pipe into the thermostatic valve 3, and another portion of which is directly delivered into the thermostatic valve 3 via the three-way pipe 2. For the thermostatic valve 3, the user generally adjusts the outlet water temperature, and the mixing ratio of the cold water and the hot water is automatically adjusted by utilizing the function of automatically adjusting the water temperature of the thermostatic valve 3. For example: when the outlet water temperature of the thermostatic valve 3 is adjusted to be 38 degrees and the hot water temperature in the water tank 1 is adjusted to be 50 degrees, the mixing amount of the cold water and the hot water is controlled through the thermostatic valve 3, so that the 38-degree water is directly output for users to use.
The specific structural form of the thermostatic valve 3 may refer to a thermostatic valve in the conventional art, and is not limited or described herein.
In some embodiments, the inlet pipe 11 and the outlet pipe 12 are disposed at a lower portion of the water tank 1 for aesthetic appearance effects; the electric water heater also comprises a shield 4, and the water inlet pipe 11, the water outlet pipe 12 and the three-way pipe 2 are positioned at the rear side of the shield 4. Specifically, can shelter from inlet tube 11, outlet pipe 12 and three-way pipe 2 through guard shield 4, and then optimize whole outward appearance effect. For the convenience of installation, the protective cover 4 can be installed on the water tank 1 in a clamping manner, and the clamping installation manner can be in a form that a clamping claw is matched with a clamping groove, such as: be provided with the jack catch on the guard shield 4, and dispose corresponding draw-in groove on the water tank 1, accomplish the equipment of guard shield 4 and water tank through the jack catch and the cooperation of draw-in groove.
In another embodiment, for the convenience of the user, a mounting opening may be further provided on the shield 4 through which the knob 30 of the thermostatic valve 3 protrudes to the front side of the shield 4. The knob 30 of the thermostatic valve 3 is extended to the outside of the shield 4 through the mounting opening, and the user can conveniently operate the thermostatic valve 3 at the front side of the shield 4 to improve the convenience of use.
In one embodiment, in order to conveniently connect the three-way pipe 2 and the thermostatic valve 3 together, the electric water heater further comprises a bypass pipe 5, and the bypass pipe 5 is connected between the second pipe orifice and the second inlet 32. Specifically, the bypass pipe 5 serves as a water flow path between the three-way pipe 2 and the thermostat valve 3 for conveying the water flow output from the three-way pipe 2 into the thermostat valve 3 via the bypass pipe 5. The bypass pipe 5 can be a straight pipe, and in order to meet the installation requirements of the three-way pipe 2 and the thermostatic valve 3 for position adjustment, the bypass pipe 5 can also be a corrugated pipe. The bypass pipe 5 has an inner diameter gradually reduced in the water flow direction, thereby satisfying the supply of more cold water into the water tank 1.
In some embodiments, a one-way valve (not shown) is further disposed in the bypass pipe 5, and the one-way valve is used for controlling the water output from the second nozzle to flow into the second inlet 32 through the bypass pipe 5. Specifically, through configuration of the one-way valve, the three-way pipe 2 can be ensured to respectively convey cold water to the water tank 1 and the thermostatic valve 3, and therefore hot water output from the water tank 1 is prevented from flowing back to the three-way pipe 2 through the thermostatic valve 3 due to special conditions.
In a preferred embodiment, a stop valve (not shown) may be further provided on the bypass pipe 5 in order to meet the requirement of the user for high-temperature water. Specifically, the thermostat valve 3 has an upper limit value for the temperature of the regulated output, and the maximum temperature of the water output from the thermostat valve 3 for home use does not exceed 50 degrees in general. And under the special condition, when the user needs to use the hot water that exceeds the highest outlet water temperature of the thermostatic valve 3, then cut off the bypass pipe 5 through the stop valve to make the three-way pipe 2 can not directly provide cold water to the thermostatic valve 3, like this, the thermostatic valve 3 just only outputs the hot water in the water tank 1, in order to satisfy user's different water requirements.
Compared with the prior art, the utility model discloses an advantage is with positive effect: through dispose the thermostatic valve on the outlet pipe to corresponding dispose the three-way pipe on the inlet tube, the three-way pipe is satisfying under the requirement that the water tank intake, can also supply cold water to the thermostatic valve simultaneously, and the user only need satisfy the requirement of direct water consumption through adjusting the thermostatic valve, and then need not additionally to dispose muddy water valve again, and the thermostatic valve of configuration on the water tank can the hot water output quantity of automatically regulated water tank and the cold water output quantity of three-way pipe, more be favorable to improving user experience nature and convenience in use.
The above embodiments are only used to illustrate the technical solution of the present invention, and not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments described in the foregoing embodiments, or that equivalents may be substituted for elements thereof; such modifications and substitutions do not depart from the spirit and scope of the present invention, which is claimed.
