When baking is carried out, the hole cover opening and closing cylinder contracts to enable the hole cover to seal the observation hole, and at the moment, the driving head presses the driving rod to drive the valve plate to seal the air inlet channel. Open the light and observe through the through-hole when needing to observe the box inside.

When the transformer in the box body needs to be removed and the temperature is reduced, the hole cover opening and closing cylinder extends to drive the hole cover switch, at the moment, the pressing head loses the pressing effect on the driving rod, the valve is controlled to be opened under the effect of the valve opening spring, and the gas from the source output is input into the box body to discharge hot gas in the box body.

The transformer is moved into and out of the tank by moving from the lower plate.

After the sun irradiates the heat absorption end of the heat pipe of the heat storage box part, heat is absorbed by the heat absorption end of the heat pipe of the heat storage box part and is dissipated from the heat dissipation end of the heat pipe of the heat storage box part, and therefore fluid in the heat storage box is heated. When the baking is needed, the circulating pump is started to enable the hot fluid in the heat storage tank to flow through the heat exchanger to circulate, and the hot fluid is used as a heat source for baking in the baking oven. The part of the sun which is irradiated away from the side of the heat absorption end of the heat pipe of the heat storage box part irradiates the reflector and is reflected back to the heat absorption end of the heat pipe of the heat storage box part by the reflector for utilization, thereby improving the utilization rate of solar energy. When the reflector driving mechanism is used, the rotating angular speed of the reflector is equal to the rotating angular speed of the sun with the reflector as the center, so that the reflector always keeps facing the sun, and poor heating effect caused by backlight is prevented.
