Square inner-container storage water heater

Abstract

The invention provides a square inner-container storage water heater. The square inner-container storage water heater comprises a shell, an inner container, a heating device and a plurality of pressure reducing devices, wherein the shell, the inner container and the heating device are arranged in the shell; the inner container is approximately square; the heating device is used for heating water in the inner container; the pressure reducing devices comprise non-full water tanks; the water tanks are connected with pressure relief holes of the inner container; and the plurality of pressure reducing devices are connected together to form multi-stage pressure reduction. When the pressure is over high, water in the inner container flows towards the pressure reducing devices in order to reduce the pressure in the inner container. The pressure of the inner container is lowered continuously through the multi-stage pressure reduction of the plurality of pressure reducing devices, so that swelling of the square inner container under a high pressure is avoided. The pressure on the square inner container is lowered in order to make the shape of the inner container fit a wall surface, so that abasis is laid for the square water heater. Meanwhile, the plurality of pressure reducing devices can be used for compensating pressure for portions with insufficient pressure, so that a shower head can keep constant water pressure, and the bathing experience of the user is improved.

Description

technical field [0001] The invention relates to a water storage type water heater with a square liner. Background technique [0002] Water storage type electric hot water is widely used, but the existing electric water heaters are all cylindrical or elliptical cylindrical, and the direct surface of the wall belongs to the line surface, and the highest point and the lowest point of the wall are hung on the wall. There is a large amount of unusable space, resulting in a great waste of space, and at the same time, the front end protrudes and takes up space. The reason is that the inner tanks of the existing water storage type electric water heaters are all cylindrical or elliptical cylindrical inner tanks , the square inner tank cannot be used for water storage due to its insufficient pressure bearing capacity. Contents of the invention [0003] In order to solve the above problems, the present invention proposes a square liner water storage water heater, [0004] The prese...
