Problems solved by technology

However, the current thermal storage electric water heater still has the following defects: 1. The thermal insulation water tank used is generally a water tank structure with a single liner. Difficult to quickly meet usage requirements
However, the connecting pipes between existing double-inner tanks or multi-inner tanks are simply connected, so that the difference in water temperature between different inner tanks is not large, and it is difficult to achieve a rapid increase in water temperature, which brings inconvenience to people's lives.
2. The insulation layer in the thermal water tank i

Example Embodiment

[0032] Example 1

[0033] Prepare 3 parts by weight of polyether 3050, 10 parts of polyether 4110, 8 parts of polyether 2043, 0.3 parts of methyl chlorophenyl silicone oil, 5 parts of water, 2 parts of calcium bentonite, 4 parts of sepiolite fiber, cross-linked 0.1 part of the foaming catalyst, 1.5 parts of the foaming catalyst and 4 parts of the flame retardant red phosphorus. The foaming catalyst is made of copper isooctanoate, 4-pyrimidine formate, and dimethylethanolamine in a mass ratio of 1:2:6; BDO is selected as the linking agent; the above-mentioned raw materials are mixed uniformly to form a polyether composition, then mixed with 0.8 part of diphenylmethane diisocyanate, and then poured into the cavity of the water heater tank for foaming, and cured at high temperature to obtain the present invention Insulation layer of the water heater used.

Example Embodiment

[0034] Example 2

[0035] Prepare 5 parts by weight of polyether 3050, 15 parts of polyether 4110, 15 parts of polyether 2043, 0.5 parts of methyl chlorophenyl silicone oil, 8 parts of water, 5 parts of calcium bentonite, 6 parts of sepiolite fiber, cross-linked 0.2 parts of foaming catalyst, 1.8 parts of foaming catalyst and 6 parts of flame retardant magnesium hydroxide. The foaming catalyst is made of copper isooctanoate, 4-pyrimidine formate and dimethylethanolamine in a mass ratio of 2:2:6; The crosslinking agent is EG; firstly mix the above-mentioned raw materials uniformly to form a polyether composition, then mix with 0.8-1.5 parts of diphenylmethane diisocyanate, and then pour it into the cavity of the water heater tank for foaming, and obtain it after high temperature curing The thermal insulation layer of the water heater used in the present invention.

Abstract

The invention provides an electric water heater and belongs to the technical field of water heater water tanks. The electric water heater comprises a shell. Three inner containers are arranged in the shell from top to bottom. A heat insulation layer is arranged between the shell and the inner containers. The three inner containers are adopted in the electric water heater, according to the principle that hot water ascends and cold water descends, the positions of connecting pipes among a water inlet, a water outlet and the inner containers are ingeniously arranged so that hot water can rapidly and preferably reach the hot water outlet position, and the purpose of rapidly taking hot water is achieved. A common water heater is only provided with one temperature sensor to detect the temperature of a water outlet, however, the electric water heater is provided with multiple temperature sensors and multiple heating devices in the different inner containers to achieve classified heating, and therefore control can be more accurate. The electric water heater has the beneficial effects that the water temperature increasing speed is high, the heat preservation effect is good and lasting, and use is safe and healthy.

Description

[0001] 【Technical Field】 [0002] The present invention relates to the technical field of water heater tanks, in particular to an electric water heater. [0003] 【Background technique】 [0004] Due to simple installation, safe and convenient use, low price and other reasons, electric water heaters are one of the most popular types of water heaters. The high efficiency, energy saving and power saving of electric water heaters have always been the goals pursued by the water heater industry. However, the current thermal storage electric water heaters still have the following shortcomings: 1. The thermal insulation water tank used is generally a single-lined water tank structure. The cold water pipe enters from the lower part of the thermal insulation water tank, and the hot water pipe is led out from the upper part of the thermal insulation water tank. The hot water in the water tank It is difficult to quickly meet the requirements for use. In response to this problem, water heaters w...
