Description

Energy-saving water heater with insulation layer (I)

The present invention relates to an energy-saving interlayer water heater, the purpose of which is to reduce the heat conduction effect to extend the continuous heat preservation time of the hot water inside the inner barrel of the water heater.

A water heater is a necessary device in life. Its function is to raise the temperature of water source (e.g. tap water) from normal temperature to the target temperature. The most common application is to heat tap water in winter to provide users with hot water for bathing.

Water heaters are generally classified into gas-heating type and electric-heating type in terms of heating method. Gas-heating type produces carbon monoxide, which is a deadly exhaust gas, when burned. Carbon monoxide is a deadly exhaust gas that must be discharged outdoors. Therefore, there are many restrictions on the installation location of gas-heating type water heaters. They must be installed in areas where exhaust gas can be discharged. This is not easy for many residents, so many residents will choose to use electric-heating type water heaters. However, compared with gas-heating type water heaters, although electric-heating type water heaters do not produce deadly exhaust gas during use, the common basic type power consumption is basically above 4kw, which has the disadvantage of high power consumption.

In view of the above content, it can be known that how to develop an electric water heater that improves the efficiency of hot water supply to save electricity expenses and energy consumption is a problem that needs to be solved with great priority.

In order to increase the heat preservation time of hot water, the present invention first sets an inner barrel inside the outer barrel, and the inner barrel is used to store hot water. In addition, a vacuum insulation board is attached to the outer side of the inner barrel as much as possible. The vacuum insulation board has a very low thermal conductivity coefficient, so it can effectively slow down the heat energy of the hot water inside the inner barrel to dissipate outward. In addition, the remaining space between the outer barrel and the inner barrel is filled with a second insulation layer. In this way, the heat conduction effect of hot water to the outside can be effectively reduced without increasing the volume of the water heater, thereby extending the continuous heat preservation time of the hot water inside the inner barrel of the water heater. Therefore, the present invention is indeed novel and progressive.

To achieve the above-mentioned purpose and effect, the present invention provides an energy-saving water heater with insulation layer, which includes: an outer barrel; an inner barrel, which is located in the outer barrel; a first heat-insulating layer, which includes a plurality of vacuum insulation panels, each of which includes two high-barrier films, the edges of the two high-barrier films are heat-sealed and connected, and there is a vacuum space inside, the vacuum space of each vacuum insulation panel is filled with glass fiber, and the plurality of vacuum insulation panels are attached to the periphery and both sides of the inner barrel; a second A heat preservation layer, which is attached to the inner wall of the outer barrel; a cold water pipe, one end of which is exposed outside the outer barrel, the cold water pipe partially penetrates the inner barrel and the outer barrel, and the other end of the cold water pipe is located inside the inner barrel; a hot water pipe, one end of which is exposed outside the outer barrel, the hot water pipe partially penetrates the inner barrel and the outer barrel, and the other end of the hot water pipe is located inside the inner barrel; a heating device, which is at least partially located inside the inner barrel; a control device, which is electrically connected to the heating device.
