The invention relates to a
heat pipe-type steamer and a control method thereof. The
heat pipe-type steamer comprises a main body, a steam
recovery device and a recovered
steam heating chamber, which are in the end-to-end connection to form a
heat pipe loop using the steam as heat-transfer medium. The recovered
steam heating chamber is the heat
pipe heat-absorbing end. The steam
recovery device is the heat
pipe heat-dissipating end. The main body is the heat
pipe body. A built-in heat source is arranged inside the recovered
steam heating chamber. The steam of the heating chamber is heated by the built-in heat source, then flows through the heat pipe body and reaches the heat pipe heat-dissipating end, and finally flows back to the recovered steam heating chamber and is heated by the built-in heat source again. In the heat pipe loop, the steam is circulated by the
convection and upward-floating and the food inside the main body is heated by the circulated steam. In the control method, the
cooking process is set in a heat pipe-type steam circulation mode and a steam jet
driving mode. When the steam inside the steamer is insufficient, the
cooking process is completed in the steam jet
driving mode. After the steam is supplemented and the
steam temperature reaches the upper limit for cooking, the
cooking process is completed in the heat pipe-type steam circulation mode. The food is heated in the two
modes alternately.
