Description

Solar energy-electric energy associating one kitchen range

Technical field

The utility model relates to a kind of kitchen range, more particularly, relates to a kind of solar energy-electric energy associating one kitchen range that can utilize solar energy and electric energy simultaneously.

Background technology

At present, because of rising violently of energy shortage and price, the cry of energy-saving and emission-reduction is day by day surging, is very important to making full use of of solar energy therefore.

Aspect kitchen range, the solar range or the solar energy-electric energy associating one kitchen range of solar energy occurred directly utilizing, but this kitchen range volume is big, the cost height, operation easier is big, and sunlit outdoor application must be arranged by day, thereby has greatly limited the universal use of solar energy stove.

In the solar water heater application facet, development in recent years is very fast, but it only is used to provide sanitary water, does not have otherwise purposes.Particularly solar irradiation abundant season, because temperature is higher, the high-temperature-hot-water that solar water heater produces is not fully used.

Summary of the invention

In order to overcome the existing deficiency that the solar range use occasion is limited and the solar energy utilization ratio is not high, the utility model provides a kind of solar energy-electric energy associating one kitchen range, can be in indoor use, maximally utilise the solar water heater of popularizing day by day, even connect under the unserviceable situation of cloudy solar energy in a few days, also can owing to adopted the adiabatic electrical heating design of insulation, goodish power savings be arranged also directly with the electrical heating operation.

The technical scheme that its technical problem that solves the utility model adopts is:

A kind of solar energy-electric energy associating one kitchen range, comprise solar water heater, heat-preserving container and container, container places in the heat-preserving container, described container comprises electric heater unit, the hot water that solar water heater produces, enter in the heat-preserving container through water intaking valve, water inlet pipe, outlet pipe is equipped with in the heat-preserving container bottom, is connected with overflow pipe on the outlet pipe and extends to the outside to be connected with discharging valve.

Its operation principle is: the hot water that utilizes existing solar water heater to produce, enter in the heat-preserving container through water inlet pipe, and place container in the heat-preserving container, the external diameter of container is than the approximately little 10～20mm of internal diameter of heat-preserving container, and also there is 10～20mm spacing the bottom apart from heat-preserving container.Be at discharging valve under the situation of closed condition, open water intaking valve, it is heated from the neighboring that the hot water of solar water heater will flow under pressure into heat-preserving container and be full of container.Because container absorbs heat, cause the hot water temperature in the heat-preserving container to descend.Continue to flow at hot water under the situation of heat-preserving container, the lowered water of temperature sinks to the bottom greatly because of density becomes, and flows out through overflow pipe from outlet pipe.After several minutes, the drinking water in kettle or the pot or other materials just can be heated to the temperature near solar water.Simultaneously, because electric heating plate or electric heater are housed in container, when the hot water from solar water heater can't further heat up container, can connect power supply continuation heating and achieve the goal.

In an embodiment of the present utility model, described container is a pot, comprise pot cover, pot body, electric heating plate and basin body, the pot body is suitable for reading directly to stamp out the pot edge, the diameter of pot edge is greater than the internal diameter of heat-preserving container, on the pot edge, be welded with handle, handle inside is equipped with stealthy outlet, power lead by handle to a pot body end, pass metal tube and extend to bottom of pot body, electric heating plate is installed in bottom of pot body, the binding post of electric heating plate with join from the power line in the metal tube, basin body becomes an integral body with the roll welding of pot body, and carries out embedding with the high-temperature-resistant thermal-insulation material.

In another embodiment of the present utility model, described container is a kettle, comprise pot lid, kettle body, Hu Zui, Hu Kou and electric heater, Hu Zui is installed in the top of kettle body, Hu Kou is equipped with the kettle edge, kettle along be welded in Hu Kou with support that the kettle body links to each other on, electric heater is installed on the pot lid, handle is installed in Hu Yanshang.

The beneficial effects of the utility model are, the kitchen range institute energy requirement overwhelming majority is from solar energy, and effects of energy saving and emission reduction is remarkable.

To cook congee is example, the water temperature of supposing the solar water heater in night is 95 ℃, the pot that certain water gaging and rice are housed is positioned in the heat-preserving container, open water intaking valve, rice and water after a few minutes in the pot just can be heated to more than 90 ℃, at this moment close water intaking valve, connect power supply, only needed about 1 minute just congee can be heated to boiling, can cut off the electricity supply.At this moment, because the heat insulating function of heat-preserving container causes whole hot water energy to remain on staving inside, thereby guaranteed congee required heat energy in maturing process.Than using in electric cooker, the electromagnetic oven economize on electricity 90%.

Be example to boil water again, the water temperature of supposing solar water heater is 90～95 ℃, the kettle of filling water is positioned in the heat-preserving container, open water intaking valve, just can make the temperature of the interior water temperature of kettle after a few minutes near solar water, can satisfy this moment and make tea and directly drink, also can connect power supply, just can reach boiling point less than 1 minute.Use kitchen range of the present utility model, kettle is placed in the heat-preserving container, and its heating surface area ratio is much bigger with the heating surface area of other heat forms such as combustion gas or electrical heating, the energy-saving effect highly significant.

Because service life of solar water heater is very long, and reason such as the production cost of these kitchen range is low, so the comprehensive use cost of these kitchen range is significantly less than combustion gas, fire coal, combustion faggot etc.
