The solar cooker is another way of utilizing solar energy, various solar cookers such as a box type solar cooker, a flat plate solar cooker and a condensing solar cooker have been designed, the solar cooker can directly convert light energy into heat and cook food, but a user needs to manually operate in hot sunlight, so that the use enthusiasm of the user on products is reduced, in addition, the solar cooker is in an idle state when not cooking, and the overall utilization rate is lower.
For the device for directly introducing sunlight into a room, special modification and design of a house are required, so that the manufacturing cost of equipment is increased, and the feasibility of implementation is reduced.
Another common solar energy utilizing device is a solar water heater, which utilizes a vacuum tube or other heat collecting devices to collect heat, which is a relatively effective way to utilize solar energy, but the solar water heater has high requirement on water quality, and when minerals or impurities in water exceed a certain proportion, the system often reduces efficiency due to precipitation of impurities, and even cannot work normally. In cold areas, the water heater cannot be used normally because the water in the pipe is easy to freeze. In addition, the solar water heater is high in maintenance cost, single in function and cannot be used for other functions such as heating.

The first interface 89 is located on top of the hot water reservoir 83 and is connected to the inlet of the indoor heat application device 10. As shown in fig. 1 and 2, when the indoor heat application device 10 supplies heat to the indoor space, the outlet of the indoor heat application device is connected to the heat exchange chamber 84 via the second interface 90, and meanwhile, the second interface 90 is connected to an external water source, and in this embodiment, the second interface 90 is a two-way joint, a three-way joint or a multi-way joint. As shown in fig. 5 and 6, when the indoor heat application device 10 supplies hot water to the indoor, the external water source communicated with the second port 90 injects cold water into the heat exchange chamber 84, and the hot water in the upper hot water storage chamber 83 is pushed out to the indoor heat application device 10 through the first port 89.

Because the volume of the heat storage water cavity 83 is big, the temperature of the water in the upper portion of the heat storage water cavity 83 is high, the density is relatively small, the temperature of the water in the lower portion is low, the density is relatively big, the heat insulation cold water conduit 86 is arranged to enable the low temperature water in the lower portion of the heat storage water cavity 83 to be effectively guided into the heat exchange cavity 84 without being mixed with the high temperature water in the upper portion of the heat storage water cavity 83, the low temperature water circulated into the heat exchange cavity 84 is heated by the heat exchange tube 94 and then flows upwards to the upper portion of the heat storage water cavity 83 through the heat insulation hot water conduit 85, and therefore the fact that the high temperature hot water is always present in the upper portion of the heat storage water cavity 83, and the temperature of the water flowing out through the first interface 89 is the highest in the heat storage water cavity 83 is guaranteed.
