Technical field
The utility model relates to heater assembly, a kind of specifically heater assembly with vacuum heat-insulating layer.
Background technology
Heater assembly is a kind of through other forms of energy is converted into heat energy, passes to a kind of energy conversion device that needs heatable substance again.Such as electric kettle, electric cooker, water heater, boiler or the like, be seen everywhere in the daily life.In order to make heater have heat insulation effect, generally increase some and have the material of heat insulation function in the heater outside, improve the service efficiency of heat in heating or the insulating process, have positive role simultaneously for cutting down the consumption of energy.But the insulation material that uses quality directly influences heat insulation effect, and the while lost environmental factor that receives of heat is very big, is better than winter such as the heat insulation effect in summer.
Scattering and disappearing of heater heat said from physical angle, mainly caused by the heat transmission, comprises heat conduction and convection current.The heat of eliminating or reducing this kind form scatters and disappears, with the service efficiency that increases heater assembly greatly.
Summary of the invention
The utility model technical problem to be solved is to the above-mentioned state of the art, and high insulating effect, the few a kind of heater assembly with vacuum heat-insulating layer of heat conduction dispersed heat are provided.
The utility model solves the problems of the technologies described above the technical scheme that is adopted:
A kind of heater assembly with vacuum heat-insulating layer comprises the heater housing and is assemblied in the heating tank in the heater housing, wherein, is provided with vacuum heat-insulating layer between heater housing and the heating tank.
For optimizing technique scheme, the concrete measure of taking also comprises:
The vacuum heat-insulating layer inner surface pastes with heating tank mutually joins, and outer surface pastes with the heater housing mutually joins.
Heating tank is connected with water inlet and the delivery port that runs through vacuum heat-insulating layer and heater housing simultaneously.
Heating tank is connected with heater, and heater is connected with external power supply.
Be fixed with the heater attemperating unit that to control the heater switch on the heater housing.
Heating tank is connected with the steam hole that runs through vacuum heat-insulating layer and heater housing simultaneously.
Compared with prior art, a kind of heater assembly with vacuum heat-insulating layer of the utility model comprises the heater housing and is assemblied in the heating tank in the heater housing, wherein, is provided with vacuum heat-insulating layer between heater housing and the heating tank.Around the heating jar, increase by a vacuum layer, prevent that heat from carrying out heat transmission through convection type.This vacuum layer opposite side and heater housing adopt specific technology to form a seal cavity, make the sealing space form vacuum layer through a series of processing technology then.Through elimination convective heat transfer mode, and then reduce to the full extent, improve the service efficiency of heater assembly to the full extent by heat conduction dispersed heat.
The utlity model has high insulating effect, the few advantage of heat conduction dispersed heat.
Description of drawings
Fig. 1 is the structural representation of the utility model.
The specific embodiment
Embodiment to the utility model describes in further detail below in conjunction with accompanying drawing.
Shown in Figure 1 is heater housing 1, delivery port 2, vacuum heat-insulating layer 3, water inlet 4, heater 5, heating tank 6, heater attemperating unit 7, steam hole 8.
As shown in Figure 1, the utility model
A kind of heater assembly with vacuum heat-insulating layer comprises heater housing 1 and is assemblied in the heating tank 6 in the heater housing 1, wherein, is provided with vacuum heat-insulating layer 3 between heater housing 1 and the heating tank 6.
Among the embodiment, vacuum heat-insulating layer 3 inner surfaces paste with heating tank 6 mutually joins, and outer surface pastes with heater housing 1 mutually joins.
Among the embodiment, heating tank 6 is connected with the water inlet 4 and delivery port 2 that runs through vacuum heat-insulating layer 3 and heater housing 1 simultaneously.
Among the embodiment, heating tank 6 is connected with heater 5, and heater 5 is connected with external power supply.
Among the embodiment, be fixed with the heater attemperating unit 7 that to control heater 5 switches on the heater housing 1.
Among the embodiment, heating tank 6 is connected with the steam hole 8 that runs through vacuum heat-insulating layer 3 and heater housing 1 simultaneously.Steam hole 8 reduces heating tank 6 internal pressures in order to get rid of the vapours in the heating tank 6.
In the present embodiment, water inlet 4 inserts normal-temperature water, and heater 5 inserts the required power supply of heating tank, simultaneously heater attemperating unit 7 is connected with heater 5, and heating-up temperature is controlled automatically.Around heating tank 6, increase by a vacuum heat-insulating layer 3, prevent that heat from carrying out heat transmission through convection type.These vacuum heat-insulating layer 3 opposite sides and heater housing 1 adopt specific technology to form a seal cavity, make the sealing space form vacuum through a series of processing technology then.Through elimination convective heat transfer mode, and then reduce to the full extent, improve the service efficiency of heater assembly to the full extent by heat conduction dispersed heat.But owing to the existence of the delivery port 2 that penetrates vacuum heat-insulating layer 3, water inlet 4, heater 5 etc., heating tank 6 is not accomplished and extraneous vacuum insulating, so hot gas still can run off very slowly.When to heating tank 6 heating; Heater 5 energisings; Heating tank 6 is heated, and when heating tank 6 temperature reached predetermined temperature, the heater attemperating unit 7 that is fixedly installed on the heater housing 1 was sensed through its inner internal temperature inductor; And the power supply of cut-out heater 5, whole heating tank device is in keeping warm mode.At this moment owing to also have faint hot transport phenomenon, hot gas still can run off very slowly, and heating tank 6 temperature can descend gradually; When dropping to uniform temperature, heater attemperating unit 7 begins to start, and makes heater 5 energized once more; Heater 5 reheats, and overheated temperature control is contained in heater attemperating unit 7 inside, when appearance in heating tank 6 heating processes is unusual; Overheated temperature control is cut off the electricity supply, and stops heating.
The most preferred embodiment of the utility model is illustrated, and various variations of being made by those of ordinary skills or remodeling can not break away from the scope of the utility model.
