Abstract

The utility model relates to a heat-preservation kettle which is heated by solar energy and consists of an inner shell body and an outer shell body, vacuum is formed by deflating the air between the inner shell body and the outer shell body, one side of the outer shell body consists of transparent material which has high sunshine transmission rate, but has low transmission rate being relative to the heat radiation of other wavelength, the inner shell is made of metal material with good heat conduction, one side corresponding to the transparent side of the shell is made into a water-wave shape and is coated with a selective coating which has the performance of high absorption rate to the heat radiation and extremely low self heat radiation emission rate; when the sunshine passes through the transparent part of the shell and shines on the selective coating of the water-wave shape heat absorption surface of the inner shell, most part of heat energy can only be conducted into the water in the shell so as to ensure that the water can be heated rapidly, and the heat preservation is good because the inner shell and the outer shell is vacuumized, simultaneously, the kettle is also provided with an internal-mounted bracket, so as to ensure that the light receiving surface aims at the sun better and absorbs the sun energy to the utmost extent.

Description

The solar heating and thermal insulating kettle

Affiliated technical field: the utility model relates to a kind of especially a kind of insulation kettle with solar energy heating of kettle that is incubated.

Background technology:

At present, known insulation kettle all is to adopt double Shell, and the air between the double Shell extracted out to form vacuum reach the insulation purpose, though having realized heat-preserving function but must be putting into kettle after the water heating, self does not have heating function, add the also necessary consumes energy of hot water simultaneously, cause air pollution indirectly, adding hot water sometimes neither be very convenient.

Summary of the invention:

Solve the problem that insulation kettle can not self heating in order to make full use of this clean energy resource of solar energy, the utility model provides a kind of kettle that can be incubated and can heat with solar energy.

The technical scheme that the utility model addresses this problem is: the inner casing of making kettle with heat-conductive characteristic preferred metal material, an one side made ripples line shape and scribble sunshine is had high-absorbility, and the very little selective coating of heat radiation emissivity of self, outside inner casing, make a side and have high transmission performance and the transparent material the smaller the better the radiation transmission of the light outside the solar spectrum for sunlight, opposite side is the shell that metal or other suitable material are formed, two kinds of materials connect airtight, make the coating position of a transparent side over against inner casing, and between two housings, deflate, form vacuum.The coating of inner casing is accepted sunlight absorption heat by the transparent shell of shell under the irradiation of sunlight, simultaneously because heat radiation is low, the shell transparent material is little to its heat radiation permeability, again owing to not heat conduction of vacuum makes these heats to conduct to the water in the inner casing by inner casing, thereby reach the purpose that adds hot water.

The beneficial effects of the utility model are that kettle can heat, and especially can use solar energy heating, the insulation of heating back.Energy-saving and environmental protection, convenience.

Below in conjunction with accompanying drawing the utility model is further specified:

Figure one is that kettle body profile figure two is front appearance figure

Figure three is bottom side outside drawings

1, over cap 2, kettle plug 3, support 4, inner casing ripples line heat-absorbent surface 5, shell hyalomere 6, heat-resisting blob of viscose 7, shell 8, inner casing 9, handle can be hung braces 10, cushion block 11, inner casing bracket groove

Description of drawings:

Among the figure, kettle plug (2) is outer over cap (1), self has ventilating opening to play thermal loss Little, as not backed down by pressure during heating effect after the heating covers over cap, reaches the purpose of insulation, and is anti-Hot glue piece (6) is some to separate shell (7) and inner casing (8), makes it directly not contact, and takes out true between two shells The effect of thermal loss when sky plays insulation and reduces heating. Support (3) can be packed up when not heating with at the bottom of the kettle one Flat, easy to carry, can open the supporting role of playing the kettle body during heating, make the kettle body keep the best of heat absorption Angle, water ripples heat-absorbent surface (4) play increases the inner casing heat-conducting area with the effect of raising heat conduction efficiency, its The selective coating that the surface scribbles plays heat absorption efficiency height, the low overwhelming majority that recepted the caloric to guarantee of emissivity Conduction is to the effect of water-in-kettle, and the shell transparent body (5) is selected has high percent of pass to sunlight, and to other The heat radiation of object but has extremely low permeability material manufacturing, plays local greenhouse effects, and it is sharp to improve heat Use efficient. Kettle is conveniently picked up and put down to handle among the figure two (9), can hang braces simultaneously, is convenient for carrying figure Cushion block in three (10) prevents from scratching when kettle is placed on duty.

The specific embodiment:

In the time of need adding hot water; kettle is filled water; kettle plug (2) is covered; the support (3) of opening the kettle back side makes kettle in an angle with the horizontal; allow the front be that hyalomere (5) is over against solar direction; sunlight is radiated on the selective coating on the inner casing ripples line surface (4) with high permeability; because selective coating has the high-absorbility to sunlight; self but has extremely low radiant emissivity; the radiation of minute quantity is intercepted because of the low transmission of the hyalomere (5) of shell again; stoped the conduction of heat simultaneously owing to the vacuum between two shells; water is wherein given in most conduction so selective coating recepts the caloric; water is effectively heated; kettle plug (2) has air-vent to make the expansion of water in heating process can not form too big pressure and have potential danger; heating can be used after finishing and also can cover over cap (1) and be incubated preservation, and this is very important for night or when not having sunlight.

Claims

1, a kind of solar heating and thermal insulating kettle is formed the kettle body by shell and inner casing, it is characterized in that vacuumizing between two shells, and the corresponding inner casing of the hyalomere of shell one side scribbles the heat-absorbent surface of the ripples line shape of selective coating.

2, solar heating and thermal insulating kettle according to claim 1 is characterized in that the side that inner casing scribbles selective coating makes ripples line shape, to increase heat transfer area.

3, solar heating and thermal insulating kettle according to claim 1 is characterized in that the kettle plug adopts the air-vent structure, so that thermal loss is very little during heating, and the kettle plug is not backed down by pressure.
