摘要:
A small steam generator uses a cylindrical steam generation vessel having a steam generation portion formed to store an amount of water for generating steam and a steam passage portion formed on the upper end of the steam generation portion for spouting steam generated in the steam generation portion. A heater element is disposed within the steam generation vessel, and an induction heating coil is wound around the periphery of the steam generation vessel for energizing the heater element. The heater element is energized by supply of electric power to the heating coil so that steam generated by boiling of the water in the steam generation portion spouts upward from the steam passage. In the steam generator, a steam discharge duct is mounted on the upper end of the steam passage for receiving the steam spouting upward from the steam passage and to discharge it in a lateral direction such that drops of hot water adhered to a ceiling surface of the discharge duct fall and re-circulate back into the steam generation part.

The subject of the present invention is to provide a steam generator constructed small in size. A steam generator 20 of the present invention is composed of a cylindrical steam generation vessel 30 having a steam generation portion 31 formed to store an amount of water for generating steam and a steam passage 32 formed on the upper end of the steam generation portion for spouting steam generated in the steam generation portion, a heater element 40 disposed within the steam generation vessel 30, and an induction heating coil wound around the periphery of the steam generation vessel 30 for energizing the heater element. The heater element 40 is energized by supply of electric power to the heating coil so that steam generated by boiling of the water in the steam generation portion spouts upward from the steam passage. In the steam generator 20, a steam discharge duct 70 is mounted on the upper end of the steam passage 32 for receiving the steam spouting upward from the steam passage to discharge it in a lateral direction such that drops of hot water adhered to a ceiling surface of the discharge duct fall and circulate into the steam generation part 31.

ObjectA cooking apparatus, wherein, independent of the quantity and the temperature of the foodstuff contained in a cooking chamber of the cooking apparatus, the food stuff can be cooked in a consistent time period by initial-heating processing and main-heating processing.Means of SolutionA cooking device is provided with a controller for performing initial-heating processing before a transition to main-heating processing. The initial-heating processing is processing which, when the temperature in a cooking chamber is dropped by a foodstuff placed in the cooking chamber, controls supply of electricity to a heater provided in the cooking chamber, and the control is performed such that the temperature in the cooking chamber rises along temperature rising line which defines a temperature rise rate at which the temperature in the cooking chamber reaches a predetermined preset cooking temperature from an initial-heating start temperature, which is set on the basis of a previously determined time period for initial heating, after the time period for initial-heating has elapsed.Selected FigureFIG. 7

An electric control apparatus for an icecream-making machine wherein a stirring paddle is settled in an icecream-forming container in conditions for thermal exchange with an evaporator of a refrigerating system and is driven by an electric motor to whip icecream ingredients stored in the container. The electric control apparatus is arranged to detect the rotational speed of the paddle for producing a pulse signal at a period inversely proportional to the detected rotational speed, to produce an output signal when 1/n of the period of the pulse signal is more than a predetermined period of time and to cease production of the output signal when 1/n of the period of the pulse signal becomes less than the predetermined period of time, and to permit supply of an electric power to the motor when production of the output signal is ceased and to cut off the supply of the electric power to the motor in response to the output signal.

A defrosting apparatus including a housing defining a space for accommodating therein articles to be defrosted, a heater for heating the air within the housing, and an air circulation fan for circulating the heated air so that it flows through the space. The apparatus further includes a first temperature sensor disposed on the air outlet side of the circulation fan for sensing the temperature of the outlet air flowing out from the circulation fan to produce a first detection signal, a second temperature sensor disposed at the air inlet side of the circulation fan for detecting the temperature of the air flowing into the circulation fan to produce a second detection signal and a controller coupled to the first and second sensors for receiving the first and second detection signals, respectively, to thereby control the operation of the defrosting apparatus. The controller includes a first comparator for comparing the temperature represented by the second detection signal with a defrosting start temperature to energize the heater when the former is lower than the latter, a second comparator for comparing the first detection signal with a reference signal to selectively deenergize or energize the heater on the basis of the reference signal, and a third comparator for comparing the temperature represented by the second detection signal with a defrosting end temperature to complete the defrosting operation when the former is higher than the latter.

An electric control apparatus for an ice making machine includes an initial water supply cycle control device for opening a water valve for a predetermined time, and a water level sensor mounted within a water tank for detecting whether or not a level of water in the water tank is more than a predetermined level. A first check-up device is provided for permitting operation of a defrost/water supply cycle and an ice making cycle when the level of water in the water tank exceeds the predetermined level after an initial water supply cycle is conducted under control of an initial water supply control device. The first check-up device also repeats operation at the initial water supply cycle when the level of water in the water tank is less than the predetermined level. A second check-up device permits operation of the ice making cycle when the level of water in the water tank exceeds the predetermined level after the defrost/water supply cycle, and repeats operation at the initial water supply cycle when the level of water in the water tank is less than the predetermined level after the defrost/water supply cycle.
