Water storing device of electric water heater

Abstract

The invention discloses a water storing device of an electric water heater, comprising a water storing cylinder, an electric heater and a water inlet and outlet tube. The electric heater is arranged outside the water storing cylinder, the water inlet and outlet tube is connected with a water storing tube and the electric heater, and the water storing cylinder consists of a plurality of layered and communicated flow guide layers. The flow guide layers comprise a plurality of flow guide grooves whirled around the centre of a horizontal partition board, wherein an outer edge flow guide groove ofa first flow guide layer is communicated with an outer edge flow guide groove of a second flow guide layer, a guide flow groove in the centre of the second flow guide layer is communicated with a flow guide groove in the middle of a third flow guide layer, an outer edge flow guide groove of the third flow guide layer is communicated with an outer edge flow guide groove of a fourth flow guide layer, and finally the outer edge flow guide grooves of the flow guide layers are communicated with a hot water outlet tube of the electric water heater. The hot water outlet tube of the electric water heater is connected with the water storing cylinder, rapid heating can be realized under the control of a CPU chip so that the hot water can be provided in a fixed amount when the electric water heater is switched on, if a hot water outlet of the water storing cylinder is closed, the hot water is accumulated in the water storing cylinder so as to prevent rapid temperature reduction due to a cold-hotmixed flow, thereby the invention has the effect of heat insulation and energy saving.

Description

technical field [0001] The invention relates to a water storage device, in particular to a water storage device for an electric water heater. Background technique [0002] In existing electric water heaters, electric heating elements such as electric heating tubes are directly placed in the water storage tank, and the water in the water storage tank is directly energized to heat the water in the water storage tank. The cold water heats up gradually, so when using hot water, there must always be a period of warm-up time. In winter and spring, it takes 1 to 2 hours to shower with hot water. Therefore, it is a practical problem that electric water heaters cannot be quantitatively heated on demand. CN2372611Y proposes an external heating electric water heater, which uses a sheet-shaped heating element outside the bottom of the water tank to heat the water tank. Although this sheet-shaped heating element can solve the problems of electric heating tube leakage, scaling, and use ...

Therefore, it is a practical problem that electric water heaters cannot be heated quantitatively on demand.

CN2372611Y proposes an external heating electric water heater, which uses a sheet-shaped heating element outside the bottom of the water tank to heat the water tank. Although this sheet-shaped heating element can solve the problems of electric heating tube leakage, scaling, and use safety, it still needs to be heated. All the water in the water tank, so it still takes time to wait for the temperature to rise, and there is still the problem of quantitative heating that cannot heat the water as needed, and how much water is used to heat how much water
