There is provided a cooker including: a cooking room; a steam generator configured to generate steam, and to supply the steam to the cooking room; a water level sensor configured to sense a water level of a cleaning solution stored in the inside of the steam generator; a supply apparatus including a storage unit configured to accommodate the cleaning solution, a supply pump configured to supply the cleaning solution accommodated in the storage unit to the steam generator, and a drain pump configured to supply the cleaning solution remaining in the steam generator to the storage unit; and a controller configured to control operations of the supply pump and the drain pump, wherein the controller operates the supply pump in a washing mode, operates the drain pump when the cleaning solution is fully filled in the steam generator, and again operates the supply pump when the cleaning solution is removed from the steam generator.

A controller monitors water temperature in a pot (41) through a water temperature thermistor in a temperature sensor (48) while a water level sensor is detecting the water level in the pot. When the water temperature in the pot exceeds 110° C., the controller determines that the water level thermistor in the water level sensor (43) cannot perform normal detection, and drives the pump (35) to supply water. When water supply based on the temperature detected by the water temperature thermistor is carried out more than three times, the controller determines that scale has deposited on the water level sensor (43), and notifies a user of a scale cleaning request. In this manner, in the case of detection failure of the water level thermistor, it is possible to notify a scale cleaning request at an appropriate time by determining whether or not the detection failure is attributable to scale deposits.

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.

In a steam cooker, for heating of a food which is a mass of granular matters or linear matters such as rice or chow mein, a steam superheater is not turned on or is turned on with a very weak electric power so that steam supplied from steam supply pipes (94A to 94C) is substantially not superheated. Steam of 80° C. to 90° C. derived from the steam supply pipe (94B) is jetted out right downward from an opening (111a) of a steam jet pipe (111). Then, steam located around an end portion of the steam jet pipe (111) in a tray-shaped case (51) is pulled in by steam jetted out from the opening (111a), so that a large amount of steam is jetted against a bowl of rice or a dish of chow mein. As a result, surfaces of, for example, rice grains are prevented from immediately going beyond 100° C., so that condensation at the surfaces of the rice grains is efficiently achieved, and supply of condensed latent heat and penetration of condensed water (hot water) to the rice grains is efficiently achieved.
