Embodiment Construction
[0027] Such as figure 1 As shown, a specific embodiment of the water storage water heater of the present invention is provided. It can be seen from the figure that a water inlet pipe 6, an outlet pipe 7 and a pressure discharge pipe 5 are arranged at the bottom of the airtight inner tank 4, and the pressure discharge pipe 5 passes through The first electromagnetic valve 1 communicates with the atmosphere, and its nozzle is located at the top gas phase space of the inner tank 4, and its height is higher than the water outlet port of the water outlet pipe 7; the water inlet pipe 6 and the water outlet pipe 7 are respectively connected in series with a second Solenoid valve 2 and the third solenoid valve 3; hot water is finally mixed with cold water through the water mixing valve 8 for users to use; all solenoid valves are electrically connected with the controller of the water heater, and two state:
[0028] State one, when hot water is used, the second electromagnetic valve 2 ...

The invention discloses a water storage water heater for reducing the pressure of the inner tank. A pressure discharge pipe communicated with the atmosphere is arranged in the gas phase space on the top of the inner tank, and a first electromagnetic valve is correspondingly arranged on the pipeline to cooperate with the water inlet pipeline. The second electromagnetic valve and the third electromagnetic valve on the water outlet pipeline are under the control of the controller, so that when the water heater uses hot water, the second electromagnetic valve and the third electromagnetic valve are opened, and the first electromagnetic valve is closed; When hot water is not used, the second electromagnetic valve and the third electromagnetic valve are closed, the first electromagnetic valve is opened, and the pressure in the inner tank is communicated with the atmosphere through the pressure discharge pipeline, so that the inner tank is in a normal pressure state. It avoids the frequent expansion and contraction of the volume of the inner tank during the electric heating process, improves the service life and safety of the water heater, and can solve the problems of water dripping and water leakage.
Description
technical field [0001] The invention relates to a water heater, in particular to a water storage water heater which reduces the pressure of an inner container. Background technique [0002] Most of the electric water heaters are water storage electric water heaters. Water storage electric water heaters are divided according to the structural form, which can be divided into closed type (pressure-bearing type) and outlet open type (non-pressure-bearing type). Single, so consumers use more closed (pressure-bearing) electric water heaters. [0003] The liner is an important part of the water heater, which is directly related to the quality of the water heater. The existing liner is divided into four types according to the material: galvanized liner, stainless steel liner, enamel liner and hot-dip galvanized liner. guts. The inner tank is a container for water and a place for heating water. The inner tank should be able to withstand the water pressure in normal use. The inner t...
