Embodiment Construction

[0026] 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:

[0027] State one, when hot water is used, the second solenoid valve 2 and the...

Abstract

The invention discloses a water storage type water heater with a function of reducing inner container pressure. The water storage type water heater is characterized in that a pressure discharge pipe communicated with atmosphere is arranged in vapor phase space in the top of the an inner container, and a first electromagnetic valve is arranged on the pipe correspondingly and matched with a second electromagnetic valve on a water inlet pipe and a third electromagnetic valve on a water outlet pipe; under the control of a controller, when hot water in the water heater is used, the second electromagnetic valve and the third electromagnetic valve are opened, and the first electromagnetic valve is closed; and when hot water is not used, the second electromagnetic valve and the third electromagnetic valve are closed, the first electromagnetic valve is opened, the pressured in the inner container is communicated with the atmosphere through the pressure discharge pipe, so that the inner container is enabled to be in a normal pressure state, frequent expansion and contraction of the volume of the inner container during an electrical heating process are prevented, the service life and use safety of the water heater are improved, and the problems of water dripping and water leakage can be solved.

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 tank. 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 tank o...
