Problems solved by technology

[0004] At present, in the process of using the thermal insulation water tanks of various household water heaters, there is generally a water pressure problem, that is, when the water volume in the thermal insulation water tank is sufficient, the water pressure of the outlet pipe is relatively high, which can ensure that the water end has a relatively turbulent water flow rate. It is suitable for showering; an

Abstract

The invention provides a constant-pressure water tank. The constant-pressure water tank comprises a columnar water tank shell made of an insulating material, wherein the lower part of the water tank shell is provided with a water outlet, the upper part of the water tank shell is provided with a water inlet, and the top of the water tank shell is provided with a pressure release valve; a water storage cavity body in the water tank shell is internally provided with an insulating piston capable of sliding longitudinally along the water storage cavity body, and the water storage cavity body is divided into an upper cold water cavity and a lower hot water cavity by the insulating piston; the lower part of the hot water cavity is connected with the upper part of the cold water cavity by a connecting pipe; the connecting pipe is internally connected with an electric control pump capable of pumping water in the cold water cavity into the hot water cavity in series; the cold water cavity is also internally provided with a temperature sensor which is electrically connected with the electric controller of the electric control pump; and when the temperature of the electric controller in the cold water cavity is higher than a preset value and the water pumping resistance is less than a preset value, the electric control pump is driven to operate, or the electric control pump is closed. The constant-pressure water tank provided by the invention has the advantages that the constant water pressure can be maintained at the water outlet of the water tank, so that the stable water discharging effect at the water consuming end is guaranteed.

Description

[0001] Technical field [0002] The present invention relates to a water tank, in particular, it is a thermal insulation water tank of a household water heater. [0003] Background technique [0004] At present, in the process of using the thermal insulation water tanks of various household water heaters, there is generally a water pressure problem, that is, when the water volume in the thermal insulation water tank is sufficient, the water pressure of the outlet pipe is relatively high, which can ensure that the water end has a relatively turbulent water flow rate. It is suitable for showering; and when the water level in the thermal water tank is low, the water pressure of the outlet pipe is low. When showering, the water from the shower head is soft and weak, and it is almost unusable. If the water tank is filled with water at this time, it will make the The water temperature drops rapidly. This problem is a common problem in domestic water heater tanks, and it is urgent...
