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 heat preservation water tank is ordinary polyurethane foam, which has insufficient heat preservation and durability. Long-term storage of water, and poor antibacterial ability, if it is not used for a long time to form stagnant water, it is easy to breed bacteria, which is not good for the health of users

Embodiment 1

[0032] Prepare 3 parts by weight of polyether 3050, 10 parts of polyether 4110, 8 parts of polyether 2043, 0.3 part of trifluoropropyl silicone oil, 5 parts of water, 1 part of pozzolan, 3 parts of asbestos wool, 0.1 part of crosslinking agent BDO, 0.3 parts of foaming catalyst and 4 parts of flame retardant magnesium hydroxide. The foaming catalyst uses copper isooctanoate, substituted-4-pyrimidine formate and Dabco TMR-4 with a mass ratio of 1-3; Parts are mixed, then poured into the cavity of the water heater tank for foaming, and the water heater insulation layer used in the present invention can be obtained after curing at high temperature.

Embodiment 2

[0034] Prepare 5 parts of polyether 3050, 15 parts of polyether 4110, 15 parts of polyether 2043, 0.5 parts of trifluoropropyl silicone oil, 8 parts of water, 2 parts of pozzolan, 6 parts of asbestos wool, and 0.2 parts of crosslinking agent EG in parts by weight , 0.5 parts of foaming catalyst and 6 parts of flame retardant magnesium hydroxide. The foaming catalyst uses copper isooctanoate, substituted-4-pyrimidine formate and Dabco TMR-4 with a mass ratio of 3:2:7; 1.5 parts of isocyanate are mixed, then poured into the cavity of the water heater tank for foaming, and after curing at high temperature, the water heater insulation layer used in the present invention is obtained.

Embodiment 3

[0036] Prepare 4 parts of polyether 3050, 13 parts of polyether 4110, 12 parts of polyether 2043, 0.4 part of trifluoropropyl silicone oil, 6 parts of water, 1.5 parts of pozzolan, 5 parts of asbestos wool, 0.15 part of crosslinking agent DEG, 0.4 parts of foaming catalyst and 5 parts of flame retardant magnesium hydroxide. The foaming catalyst uses copper isooctanoate, substituted-4-pyrimidine formate and Dabco TMR-4 with a mass ratio of 2:2:7; the above raw materials are mixed uniformly to form a polyether composition, and then mixed with 1.2 parts of isocyanate are mixed, then poured into the cavity of the water heater tank for foaming, and after curing at high temperature, the water heater insulation layer used in the present invention is obtained.

Abstract

The invention provides an energy saving and heat preserving type electric water heater and belongs to the technical field of water heater water tanks. The energy saving and heat preserving type electric water heater comprises a shell, wherein three liners are distributed in the shell from top to bottom, and heat preserving layers are arranged between the shell and the liners. According to the water heater, three liners are adopted, hot water rapidly and preferentially reaches a hot water outlet by skillfully arranging a mode for connecting a water inlet, the water outlet and the liners according to the principles that hot water rises and cold water drops, and a purpose of rapidly getting hot water is achieved. A common water heater is only provided with a temperature sensor for detecting the temperature of the water outlet, but the energy saving and heat preserving type electric water heater realizes graded heating by arranging a plurality of temperature sensors and a plurality of heating devices in different liners, thereby being more accurate to control. The water heater has the advantages of being high in water temperature rise speed, being great and lasting in heat preserving effect, being safe and healthy in use and the like.

Description

[0001] 【Technical field】 [0002] The invention relates to the technical field of water heater tanks, in particular to an energy-saving and heat-retaining electric water heater. [0003] 【Background technique】 [0004] Due to the reasons such as simple installation, safe and convenient use, and low price, 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 heater still has the following defects: 1. The thermal insulation water tank used is generally a water tank structure with a single liner. It is difficult to quickly meet the usage requirements. For this problem, there have been water heaters with double inner tanks or multiple inner tanks on the market. However, the connecting pipes between existing double-inner tanks or multi-inner tanks are simply connecte...
