Abstract
The utility model relates to a vacuum heat insulating water storage type electric water heater. The utility model comprises a water tank, a housing, a vacuum heat insulating layer, a necessary electric heating system, and a necessary waterway system, wherein, the vacuum heat insulating layer is arranged between the water tank and the housing. The water tank of the vacuum heat insulating water storage type electric water heater and the housing form cylinder shapes or conic shapes. Air absorbing material which is used for maintaining a vacuum degree for long is arranged in the vacuum heat insulating layer. The vacuum heat insulating layer of the utility model can extremely effectively stop heat being emitted to the outside through a wall surface, energy which is used for maintaining the water temperature of the utility model is greatly reduced, and the raising speed of water temperature is increased. The utility model which is suitable for a family or a hotel is used for providing bath hot water or other kinds of life hot water.
Description
The utility model provides a kind of water-storage electric heater with vacuum heat-insulating layer.
Existing family or the used water-storage electric heater in hotel only use expanded material or air layer to stop that in the water heat scatters and disappears.It is that be difficult to or impossible will making the scatter ratio, scatter and disappear ratio of heat hang down to certain degree with these methods.For water-storage electric heater, make the hot water in the water tank remain on certain temperature, both made not consume hot water, also need to keep with electric energy.Therefore, the effect of heat insulation of water-storage electric heater is directly relevant with its power consumption.Obviously, the thermal insulation of water heater is good more, and the power consumption that is used for the maintaining heat coolant-temperature gage is just few more.
The purpose of this utility model provides a kind of water-storage electric heater with vacuum heat-insulating layer, to reduce consumption of heat energy, reaches purpose of energy saving.
The utility model realizes that as follows it comprises a water tank and shell and indispensable electrical heating and water circuit system.Have airtight and the vacuum space between shell and the water tank, heat is dispersed into the external world by thermal convection current and conduction pattern in the water in order to avoid make.In the enclosed vacuum space, be provided with the gas absorbing material that is used to keep the vacuum permanency.Electric heating device is installed in the bottom of water tank, and water circuit system is located at the top of water tank.Be surrounded by the material that one deck prevents thermal radiation in water tank outside.
Fig. 1 shows one of the utility model vacuum heat-preserving water-storage electric heater embodiment.Wherein 1 is water tank, 2 is shell, and 3 are space sealing and that have the certain vacuum degree, and 4 for being used to strengthen the convex-concave link of its stability and intensity on the housing, 5 is electric heating device, 6 is gas absorbing material, and 7 is bottom, and 8 is temperature control element, 9 is water inlet pipe, 10 is loam cake, and 11 is water circuit system, and 12 for preventing the thermal radiation material.
The operation principle and the common water heater of this water heater are same or similar.Cold water enters water tank bottom by water circuit system 11 and cold water pipe 9, and heater element 5 and temperature control element 8 are responsible for water is heated to the temperature of setting, and hot water is flowing out water heater after water circuit system 11 and cold water mix.Loam cake 10 is used for decorating and insulation, and lower cover 7 is used for insulation and electrical apparatus insulation.Like this, except the outlet of bottom and upper end, whole water tank 11 is surrounded by vacuum layer, so heat loss is very little.
Along with the growth of time, have the gas generation in the vacuum chamber and vacuum is descended, so be provided with gas absorption material 6 in the chamber.
In the present embodiment, water circuit system comprises parts such as hot and cold water mixed organization that water heater is commonly used and hydraulic pressure easing valve; Comprise temperature control and overheat protector in the temperature control device 8, the function components and parts that water heaters such as earth leakage protective are commonly used.
In total heat dissipation capacity of storage water heater, heat convection accounts for the overwhelming majority with the heat conduction, and having only the small part heat is to distribute from wall by the mode of thermal radiation.Say that technically the vacuum interlayer is that elimination heat convection and heat are conducted effective method the most.
