Water tank and water heater with water tank

Abstract

The invention discloses a water tank and a water heater with the water tank. The water tank is an open water tank. The forming position of a user water returning opening of the water tank is higher than the forming position of a user water taking opening and higher than the half position of the water tank, and the forming position of the user water taking opening is higher than the forming position of a hot water inlet and the forming position of a circulation water outlet. The water tank further comprises a water level inducting device arranged in the water tank and a water replenishing control device, wherein the water replenishing control device is in communication connection with the water level inducting device and is used for controlling a user water supply pipe to be opened or closed. In this way, according to the water tank, the interior of the water tank is always in the high water level state by controlling the water level, convection heat exchanging between water in the upper portion of the water tank and water in the lower portion of the water tank can be reduced, more obvious cold and hot water layering can be formed accordingly, and the amount of produced hot water and the water using comfort degree are increased; and meanwhile the maintaining cost of the water tank is reduced, and the aims of saving energy and reducing the use cost are achieved. The invention further provides the water heater with the water tank.

Description

technical field [0001] The invention relates to the technical field of water heaters, in particular to a water tank and a water heater including the water tank. Background technique [0002] The hot water machine mainly includes a unit, a water tank, a water pipeline and a water supply pipeline. There is a circulation pipeline between the unit and the water tank. The water in the water tank flows into the heating device of the unit, and then flows back into the water tank after being heated. The water pipeline and the water filling pipeline are respectively communicated with the water tank, the water pipeline is used for introducing hot water to the user, and the water filling pipeline is used for replenishing water in the water tank. [0003] At present, the water tanks of hot water machines are divided into two types: open water tanks and closed water tanks. Among them, the open water tank is connected to the atmospheric pressure, and a water pump is installed on the wate...

AI Technical Summary

Problems solved by technology

[0007] 1. The pressure inside the water tank is higher than the atmospheric pressure, and the water tank requires high pressure resistance, so a pressure relief device needs to be installed, and the cost of the water tank is relatively high

[0008] 2. The water system has been in a relatively closed state for a long time, and it cannot be cleaned after long-term use. Due to the water quality, the water system will be scaled and cause abnormal use.
