In this type of steam discharge device, two types of steam generators with different power consumption, such as rice cookers and water heaters, are stored on the left and right sides of the storage unit, and inserted into the respective power outlets provided in the storage unit. However, this power outlet is generally designated as a rice cooker outlet and a water heater outlet. For this reason, it is troublesome for the user to memorize it or to confirm it before use.

In view of such a point, the present invention provides a switching means so that the rice cooker and the water heater can be accommodated in either of the left and right positions, and the rice cooker and the water heater may be connected to any outlet. And when a rice cooker and a water heater are used at the same time, when the breaker in the home is cut off during cooking with the rice cooker, it becomes a poor cook, but the present invention shuts off the power supply of the water heater And the technique which controls so that cooking failure does not arise by continuing energization of a rice cooker is provided.

According to a first aspect of the present invention, there is provided a steam discharge device comprising: a storage unit that stores and installs two types of steam generators that use different power; and a steam suction port that opens steam generated from the two types of steam generators into the storage unit.

When exceeding that, the current breaker is activated.

A steam discharge device according to a second aspect of the present invention is a storage unit in which two types of steam generators having different power consumption are stored and installed, and a steam suction port that opens steam generated from the two types of steam generators in the storage unit.

With both of the generators connected to one of the first and second power outlets, the control unit uses less power of the two types of steam generators based on the detection of the current detector. When controlling the switching device so that the series circuit is connected to a power outlet to which the other steam generator is connected, and when the breaker installed in the house operates based on the detection of the current detector The current breaker is activated when the current exceeds or exceeds the current.

The first invention makes it possible to store two types of steam generators with different power consumption at either the left or right position, and quickly detects that the current state is interrupted by the breaker. Since the supply line is left and the power supply line of the other steam generator is cut off, the appliance that is in trouble if the power supply is cut off during energization, such as during the cooking of a rice cooker, can be saved. The usability of the discharge device is improved and safe operation is possible.

In the second invention, a rice cooker and a water heater can be stored at any position on the left and right, and a rice cooker and a water heater may be connected to any outlet. If a water heater is detected and the switching device connects the current breaker to the energizing circuit of the water heater, and the rice cooker and the water heater are used at the same time, during cooking in the rice cooker When the household breaker is in a state of being cut off, the power supply of the water heater is quickly cut off and the energization of the rice cooker is continued, so that it is possible to control so as not to cause poor cooking. For this reason, the usability of the steam discharge device is improved and safe operation is possible.

The steam discharge device of the present invention sucks the steam generated from the two types of steam generators and stores the steam generated from the two types of steam generators from the steam inlet opening in the storage unit.

The unit corresponding to the lowest current value for is watts of power,
In the embodiment, if it is less than or equal to 1480 W), the LED of the indicator 20 is set to the first light emission state (for example, the continuous light emission state) as one of the displays of the indicator 20. A state in which the total power is equal to or higher than a predetermined upper limit (1480 W in the embodiment) for a predetermined time T6 (this time is slightly shorter than the operation time until the breaker 22 is shut off, and is set to 10 seconds in the embodiment) When the control unit 12 determines that the operation has continued, the LED of the display unit 19 is turned on, and the control unit 12 turns off the coil 23A of the current breaker (current interruption relay) 23 and turns off the contact 23B. (Open), turn off the power line of the insertion port 10A (
Open) to cut off the power supply to the water heater 11A. Thereby, it is avoided that the electric current which flows through the breaker 22 falls and interrupts | blocks, and the electric power supply of the rice cooker 11B connected to the power outlet 10B continues without interrupting | blocking. In this state, the steam exhaust fan 9 continues to operate, and the plurality of LEDs of the indicator 20 are in a predetermined second light emission state (for example, a blinking state at 1 second intervals or a slow blinking state at longer time intervals). )

Next, a water heater 11A is stored on the right side in the storage unit (storage chamber) 3 and the power outlet 1
The water heater 11A is connected to 0B, the rice cooker 11B is stored on the left side in the storage unit (storage room) 3, the rice cooker 11B that consumes more power than the water heater 11A is connected to the power outlet 10A, and the manual switching device 26 is connected. Is in a state where the change-over switch c is connected to the lower contact b. In this state, the current breaker 23 is connected to the second power outlet 10B.

In this case as well, the same operation is performed, and the total power is a predetermined upper limit (1480 W in the embodiment).
When the control unit 12 determines that the above state has continued for a predetermined time T6 (this time is slightly shorter than the operation time until the breaker 22 is shut off, and is set to 10 seconds in the embodiment), The LED of the unit 19 is turned on, and the control unit 12 turns off the coil 23A of the current breaker (current interrupting relay) 23 so that the contact 23B is turned off (opened), and the power line of the insertion port 10B is turned off ( Open) to cut off the power supply to the water heater 11A. As a result, the current flowing through the breaker 22 is prevented from being lowered and interrupted,
The power supply of the rice cooker 11B connected to the power outlet 10A continues without being cut off. In this state, the steam exhaust fan 9 continues to operate, and a plurality of indicators 20 L
The ED enters a predetermined second light emission state (for example, a blinking state at intervals of 1 second or a gentle blinking state at longer time intervals).

By the above, when it becomes possible to store two types of steam generators 11 having different power consumption at either the left or right position and the breaker 22 is cut off, the power supply line of one steam generator remains and the other In order to cut off the power supply line of the steam generator of this type, it becomes possible to relieve the troubled tool if the power supply is cut off during energization, such as during the cooking of the rice cooker 11B, and the use of the steam discharge device 1 As a result, safety can be improved.
