Description

  The present invention relates to a steam discharge unit, and more particularly to a steam discharge unit that is used to promote discharge of steam generated in a storage shelf that stores electrical appliances such as a rice cooker and an electric heat retaining pot, and has an improved power supply circuit.

  Conventionally, a steam discharge unit is incorporated in a storage shelf in order to discharge steam generated when heating an electric appliance such as a rice cooker, an electric pot, or a coffee maker stored in the storage shelf.

  In such a conventional steam discharge unit, many electric appliances that use a heater as a heat source, such as an electric rice cooker or an electric pot, are stored.

  When there is a difference in the current during cooking and when the current is kept warm, such as when the energizing current of the electric rice cooker is 8 amperes and when keeping warm, the current during cooking is detected and the blower for exhaust is turned on. Alternatively, a steam discharge unit has been proposed in which a blower is not operated when ventilation is not necessary in a process where the duty ratio is small and the ON time is short (see, for example, Patent Document 1).

However, the steam discharge unit described in Patent Document 1 is a one-line connection in which one input terminal of the steam discharge unit side power circuit is connected to one power source, and these electric appliances have a large electric capacity to use. For this reason, during use of an electric appliance, a breaker may be activated depending on the situation of an electric line in a general household, and the power supply may be interrupted.

The two duct suction ports 9a each correspond to the vent hole 4a provided in the recess forming plate 14, and the duct outlet 9b and the casing suction port 10a provided in the casing 10 of the blower 11 match. The duct outlet 9b of the duct 9 is located in the middle of the distance in the width direction of the two vent holes 4a of the recess forming plate 4, that is, the blower 11 is located in the middle of the distance in the width direction of the vent hole 4a. The duct 9 sucks the steam sucked through the steam suction port 8 and the vent hole 4a into the casing 10 through the duct blowout port 9b and the casing suction port 10a, and discharges the steam from the steam exhaust port 3 to the outside of the unit body 2. (Explanation of the point where 9a and 4a match)
The blower 11 is disposed at a substantially central portion of the front surface of the unit body 2 and includes a sirocco fan that is a centrifugal fan 11a. The centrifugal fan 11a includes a motor 11b.

  A control board 12 that controls the blower 11 is provided on one side of the unit body 2 adjacent to the blower 11.

  FIG. 8 shows a case where one power source is connected to the steam discharge unit 1 and one line of a power circuit including one input terminal, a control board, and one output terminal is used.

  The first current breaker S1 and the first input terminal 13 provided on the unit body 2 are connected by wiring, for example, when a storage shelf is installed. The first input terminal 13 is a constantly energized input terminal that is always connected to a power source (current breaker) that has been divided from the indoor distribution board, and the first input terminal 13 is a control that requires constant energization. A first current sensor 17 is attached to one side of the wiring connected to the substrate input terminal 14 and the first output terminal 15 in parallel, and connecting the first input terminal 13 and the first outlet C1. The current information signal detected by the first current sensor 17 is input to the control board 12.

  When the electrical appliances connected to the first outlet C1 and the second outlet C2 are energized, the first current sensor 17 detects the current and drives the blower 11 via the control board 12. Then, when the steam is exhausted and the electric appliance is not energized, the blower 11 is stopped via the control board 12.

  In addition, it is preferable to provide the input terminal identification means 20 so that the 1st input terminal 13 which is an always energized input terminal can distinguish the 2nd input terminal 19 which is another input terminal easily. As a result, the first input terminal 13 can be discriminated, can be reliably connected to the power source without erroneous connection, and power can be constantly supplied to the control board 12. Further, the output terminal identifying means can distinguish between the first output terminal 15 as a constant power supply output terminal fed through the first input terminal 13 and the second output terminal x as the other output terminal. 22 is preferably provided. Thereby, the outlets C <b> 1 and C <b> 2 can be reliably connected to the first output terminal 15. Examples of the terminal identification means include a cautionary note provided near the terminal or a cap placed on another terminal.

  FIG. 9 shows a case where two power supplies are connected to the steam discharge unit 1 and two power supply circuits including two input terminals, a control board, and two output terminals are used.

  In addition to the case where one line shown in FIG. 8 is used, the second current breaker S2 and the second input terminal 19 provided on the unit main body 2 are provided with a storage shelf, etc., like the first input terminal 13. Wired to The second input terminal 19 is connected to the second output terminal 21, and a second current sensor 23 is attached to one side of the wiring connecting the second input terminal 19 and the second outlet C2. The current information signal detected by the second current sensor 23 is input to the control board 12. The second input terminal 19 is connected to the second output terminal 21, and a second current sensor 23 is provided on one side of the wiring connecting the second input terminal 19 and the second output terminal 21. The current information signal attached and detected by the second current sensor 23 is input to the control board 12. Further, a second outlet C2 is connected in parallel to the second output terminal 21.

  As described above, since the steam discharge unit 1 can selectively use one or two power supply circuits, the current breaker of the input terminal and the indoor distribution board is considered in consideration of the electric capacity used by the electric appliance. The number of line connections connected to can be increased or decreased as appropriate, and the installation restrictions due to the difference in the number of power supply circuits during the installation of the steam discharge unit can be eliminated.

  As shown in FIG. 1, the steam discharge unit 1 is incorporated in the upper part of the storage shelf 31, and electric appliances such as a rice cooker and an electric warming pot are stored in the storage part 32 of the storage shelf 31.

  When the steam discharge unit 1 is used, the electric appliance is turned on and steam is generated from the electric appliance. The steam generated from the electric appliance is energized to the blower 11 and is discharged out of the unit main body 2 from the steam exhaust port 3 through the steam suction port 8 and the duct 9.

  Furthermore, when the electric rice cooker and the electric pot are energized, the first current sensor 17 and the second current sensor 23 flow when the electric rice cooker and the electric kettle that generate steam are cooked and when the hot water is cooked and when the temperature is kept warm. The electric current is detected and the blower 11 is rotated via the control board 12 when cooking rice and hot water, and the blower 11 is stopped via the control board 12 when keeping warm without generating steam. Thereby, the energy saving operation of the steam discharge unit 1 becomes possible.

  According to the steam discharge unit of the present embodiment, in consideration of the electric capacity used by the electric appliance, the line connection connected to the input terminal on the steam discharge unit side and the current breaker of the indoor distribution board can be appropriately increased and decreased. A steam discharge unit that can eliminate the restrictions on installation due to the difference in the number of power supply circuits during the installation of the unit and enables energy-saving operation is realized.

  In the above embodiment, an example using two input terminals connected to two power supplies has been described. However, even a steam discharge unit using three input terminals connected to three or more power supplies may be used. A similar effect can be obtained.
