For the ease of the understanding to specification, the below at first is further described and describes for the concrete structure of accompanying drawing 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, Fig. 6, Fig. 7 and Fig. 8.
1, structure chart forms and explanation:
Comprise among Fig. 1: supply socket 1, operation display panel 2, pot cover 3, inner pan body 4, outer pan body 5, electric heat-generating disc 6, these parts are basic elements of character that known common electric pot possesses, and the electric pressure cooking saucepan that generally uses in the market also has these basic elements of character.Feature of the present invention is to have set up on the basis of the basic comprising of above-mentioned common electric pot: solar heat transmission dish 7, high-temp liquid energy-storage box 8, energy-storage box solar energy interface 9, solar energy combination heated body (comprising the thermal-collecting tube 10 of solar thermal collector), energy-storage box valve 11, working method conversion control circuit plate 13, fluid temperature detecting sensor 14, external liquid circulation pipe 15.Its main feature is to have increased on the basis that known common electric pot (or electric pressure cooking saucepan) utilizes electric heat-generating disc to heat that solar energy is heated and heat transfer part (such as solar energy combination heated body and solar heat transmission dish etc.), particularly solar heat transmission dish is embedded in electric heat-generating disc, make the two consist of a combination heat-generating disc, and be placed in the outer pan body, the two can both heat same inner pan body separately or jointly.The effect of other parts is respectively:
Working method conversion control circuit plate, its effect is: the needs according to the power that has or not solar light irradiation and solar light irradiation and cooking operation select to use separately solar energy, use separately electric energy, solar energy and electric energy are used alternatingly, solar energy and electric energy use several working methods such as (using when generally strengthening firepower at short notice) simultaneously, the i.e. conversion of this working method and control then are to be realized by the working method conversion control circuit plate (working method conversion control circuit plate not being drawn on the outer pan body inwall among Fig. 1, because the too little difficult resolution in position) that is installed on the outer pan body inwall.The fluid temperature detecting sensor is that in the electrical connection of this working method conversion control circuit plate is used for the sensor of tracer liquid temperature, it is installed in high-temp liquid energy-storage box inwall or other can detect the position of fluid temperature, by this sensor, single-chip microcomputer on the working method conversion control circuit plate can detect the temperature of liquid in the described energy-storage box, can indirectly judge thus the power of outdoor sunshine light, and the various duties of described rice cooker are controlled.Because design and the software programming of the original figure of described control circuit board electrical equipment are fairly simple, are that general Electronics Engineer and software engineer can both be competent at the work of finishing, therefore need not be further elaborated in the inventive example.
Solar energy combination heated body is the solar energy heating part of accepting solar light irradiation, and heat-conducting liquid (such as conduction oil or water etc.) is housed in its chamber, and solar energy combination heated body intracavity liquid temperature raises fast under solar light irradiation.As previously mentioned, solar energy combination heated body inner chamber is communicated with high-temp liquid energy-storage box inner chamber, and high-temp liquid flows betwixt.If solar energy combination heated body position is lower than the position of high-temp liquid energy-storage box, the liquid that then temperature is relatively high can be because weight be relatively light, buoyancy enters in the high-temp liquid energy-storage box relatively greatly, and the liquid that temperature is relatively low sinks to solar energy and makes up continuation heating in the body cavity that is heated because buoyancy is relatively little.
The effect of high-temp liquid energy-storage box be will be communicated with it the solar energy combination endoceliac high-temp liquid that is heated temporarily be stored in the case or flow through, because solar heat transmission dish is actually the radiating surface of the upper surface of high-temp liquid energy-storage box, when having high-temp liquid to store in the high-temp liquid energy-storage box or flowing through, just can be by the heat radiation of solar heat transmission dish, i.e. the inner pan body heating of solar heat transmission dish to being placed on it.
This energy-storage box can be made into the casing of the larger energy physical holding of the stock high-temp liquid of volume, high-temp liquid stores to such an extent that more manyly more can reduce the impact that sunshine cuts in and out, make solar heat transmission dish heat dissipation capacity relatively stable within a period of time, but this moment, the use amount of liquid was relatively large, also relatively wanted high if this liquid is conduction oil then cost.In order to save cost, also the casing of high-temp liquid energy-storage box can be made into very thin casing or other special-shaped casing, its volume is reduced, only be to allow high-temp liquid flow through its inner chamber this moment, allow the high-temp liquid that flows through that inner pan body is dispelled the heat, and without the effect of physical holding of the stock high-temp liquid.
A key character of the present invention be with the design and installation of high-temp liquid energy-storage box in the inside of described rice cooker (being in the outer pan body), make energy-storage box become parts in the described rice cooker.
Energy-storage box solar energy interface is the interface that above-mentioned high-temp liquid energy-storage box is connected with solar energy combination heated body, its effect is that assurance is made up heated body with solar energy and the high-temp liquid energy-storage box can be closely linked, and makes things convenient for again the installation and removal between the two simultaneously.Adopted the flexible joint interface in the present embodiment, therefore also require solar energy combination heated body openend to be designed to the socket mouth that matches with this flexible joint interface, this socket mouth inserts the flexible joint interface and can not only guarantee to be pinned by the flexible joint interface, and sealing function arranged, guarantee that high-temp liquid can not flow out the scald user, and easily pull out easily and insert.
The effect of energy-storage box valve is when needs such as cook at the cooking operation, opens high-temp liquid energy-storage box high-temp liquid inlet port, and the liquid communication passage that energy-storage box and solar energy are made up between heated body is opened.When needs are then closed this energy-storage box valve during with outer tank heat collector heating hot water.In addition, when solar energy being made up heated body and extracts from energy-storage box solar energy interface, for guaranteeing safety and preventing that this energy-storage box valve of liquid outflow from also needing to be in closed condition.
Can consist of the basic kitchen range of disc type that saved outer pan body by above-described solar heat transmission dish and the two solar energy that forms of electric heat-generating disc and electric energy combination heater, high-temp liquid energy-storage box, energy-storage box solar energy interface, working method conversion control circuit plate and described solar energy combination heated body, can use solar energy and electric energy to heat to all pans that are placed on this combination heater.
Be that according to the difference between known electric cooker and the known voltage power pot electric pressure cooking saucepan is provided with a few safety device than electric cooker more, other structure is substantially the same.Therefore, add again on the basis that the structure of described rice cooker forms that pressure limiting valve, safety are stifled, pressure limiting valve goes out several safety such as air nozzle, high-pressure refractory ring and arranges, and the pot material of symbolization pressure cooker specification, just can make a kind of two calandria pressure cookers that can mix use solar energy and electric energy.
Fig. 2 is the outer tank heat collector, it comprises external liquid circulation pipe 15, its end is connected (as shown in Figure 1) with energy-storage box solar energy interface 9, other end joining water box radiator 17, be provided with water tank high temperature oil pump 18 therebetween, high-temp liquid can enter in the radiator of water tank when this water tank high temperature oil pump was opened.Radiator of water tank then places among the outer tank, and inner chamber and the outer tank of radiator of water tank are not connected.
The water tank high temperature oil pump is worked under the control of working method conversion control circuit plate, suppose that the outer tank heat collector is in water heater thermal-arrest state between the non-cooking operational period such as cook, its course of work is as follows: working method conversion control circuit plate is controlled first the water tank high temperature oil pump and is extracted stored liquid in the high-temp liquid energy-storage box out, close again the energy-storage box valve, then high-temp liquid is sent in the radiator of water tank through the external liquid circulation pipe by the water tank high temperature oil pump, the bore passages of fluid temperature through flowing through this radiator is to the water-cooled in the outer tank, the temperature of water raises, and the temperature of high-temp liquid reduces.Then the liquid after the cooling is sent back to solar energy combination heated body through the external liquid circulation pipe and continues to accept solar light irradiation, moves in circles with this.In order to save cost, the power that can rely on its buoyancy difference of liquid of different temperatures to produce, make high-temp liquid externally realize Natural Circulation in the heat collector for water tank, then can save the water tank high temperature oil pump, but must guarantee that the installation site of outer tank is higher than the installation site of solar energy combination heated body this moment.
Fig. 3 is that elongated body sunshine parabolic 23 makes up the outdoor sunshine heating part that heated body and heated body support 31, parabolic support 32 etc. consist of, i.e. foregoing a kind of solar energy heated body basic device with solar energy.Wherein solar energy combination heated body is the heated body that is placed on outdoor reception strong illumination, this solar energy combination heated body can be the thermal-collecting tube 10 of solar thermal collector and the assembly of solar energy heated metal pipe 22, is about to solar energy heated metal pipe and inserts combination among the thermal-collecting tube inner chamber of solar thermal collector.Also can use separately the thermal-collecting tube of solar thermal collector or use separately solar energy heated metal pipe.If only use the thermal-collecting tube of solar thermal collector, then be only suitable in the situation that liquid in pipe (such as conduction oil) temperature is not too high or air pressure (when liquid is water) the high use not, can save like this cost of solar energy heated metal pipe, and the thermal efficiency is higher, but security to differ from; If only use separately solar energy heated metal pipe also can receive strong illumination and be heated, can save like this cost of the thermal-collecting tube of solar thermal collector, and can bear high temperature and more anticyclonic impact, but its heat insulation effect is relatively poor; If be used in combination in the thermal-collecting tube with solar energy heated metal pipe insertion solar thermal collector, although cost raises relatively, security is better, and heat insulating ability is also better; The paraboloidal effect of elongated body sunshine is to strengthen intensity of illumination, assembles sunshine.The difference of it and General Parabolic face is that it can be gathered into sunray a line, rather than is gathered into a point.Can finish the strong illumination heat build-up to whole solar energy combination heated body.
Fig. 4 is the thermal-collecting tube of a solar thermal collector, and it can absorb solar energy under solar light irradiation, and heat insulation effect is better.It can adopt the thermal-collecting tube of the solar thermal collector that generally uses at present, also can be special, its opening part can be special for inserting the socket mouth of flexible joint Interface Shape, when with solar energy heated metal pipe combination (among the thermal-collecting tube inner chamber of soon solar energy heated metal pipe insertion solar thermal collector) use, it also can be special is complete transparent pipe, is the black absorber and make solar energy heated metal pipe.
Fig. 5 is solar energy heated metal pipe, and it also can absorb solar energy under solar light irradiation, but heat insulation effect is relatively poor.Its opening part is designed to the socket mouth that matches with the flexible joint interface, and ectosome is that black is easy to absorb solar energy.As previously mentioned, because solar energy heated body basic device is comprised of solar energy combination heated body and elongated body sunshine parabola etc., and solar energy combination heated body is comprised of the thermal-collecting tube of solar energy heated metal pipe and solar thermal collector, so the socket mouth of this solar energy heated metal pipe is the socket mouth of solar energy combination heated body, also is unique socket mouth that solar energy heated body basic device is connected with energy-storage box solar energy interface.
