A sensor or the like can be used.

  Here, the shutter detection sensor 21 is provided for each of the shelves A2 and A3 where the shutter 16 is to be detected. In the illustrated case, the shutter detection sensor 21 is disposed near the upper end of each of the shelves A2 and A3. Thereby, the shutter detection sensor 21 can detect the state in which the front surface is about to be closed by the shutter 16 on the shelves A2 and A3, respectively.

  Further, the control circuit 22 is disposed in an appropriate position of the home appliance storage cabinet 10, in the illustrated case, on the lower side of the bottom plate 13 and in the wheel 13 a, and as shown in FIG. The alarm device 23 is controlled based on the detection signal input from the power supply outlets 19a and 19b and the detection signals of the home appliance use sensors 19c and 19d provided in the power outlets 19a and 19b.

  Specifically, the control circuit 22 receives a detection signal from the shutter detection sensor 21 in a state where the use of home appliances is detected at the power outlets 19a and 19b provided in the shelves A2 and A3. At this time, the alarm device 23 is operated by sending a control signal to the alarm device 23. Further, when the detection signal from the shutter detection sensor 21 is lost, the operation of the alarm device 23 is stopped.

  For example, in the case of illustration, the alarm device 23 is provided on the front surface between the shelf A3 and the shelf A4 so as to be exposed even when the shutter 16 of the home appliance storage cabinet 10 is closed. The alarm device 23 includes a warning light 23a and a warning buzzer 23b in the case shown in the figure.

The operation of the shutter opening / closing control device 20 of the home appliance storage cabinet 10 will be specifically described below with reference to the flowchart of FIG.
First, in step S1, the control circuit 22 checks the use of home appliances in the shelf A2 based on the detection signal from the home appliance use sensor 19c in the shelf A2.

  When the home appliance is used in step S1, the control circuit 22 checks the shutter opening of the shelf A2 based on the detection signal of the shutter detection sensor 21 of the shelf A2 in step S2. If the shutter of the shelf A2 is about to be closed in step S2, the control circuit 22 activates the alarm device 23 in step S3, and then returns to step S1.

  If the shutter 16 is opened or not closed in step S2, the control circuit 22 determines that the shutter is opened in the shelves A2 and A3, and the alarm device 23 is activated in step S4. It is checked whether or not it is operating. If the alarm device 23 is not operating, the process directly returns to step S1. If the alarm device 23 is activated, the operation of the alarm device 23 is further canceled in step S5, and the process returns to step S1.

  If the home appliance is not used in the shelf A2 in step S1, the control circuit 22 determines the use of the home appliance in the shelf A3 based on the detection signal from the home appliance use sensor 19d in the shelf A3 in step S6. To check. When the home appliance is used in step S6, the control circuit 22 checks the shutter opening of the shelf A3 based on the detection signal of the shutter detection sensor 21 of the shelf A3 in step S7.

  If the shutter of the shelf A3 is about to be closed in step S7, the control circuit 22 activates the alarm device 23 in step S8. If the shutter 16 is open or not closed in step S7, the control circuit 22 determines that the shutter is open in the shelf A3, and the alarm device 23 is activated in step S9. It is checked whether or not the alarm device 23 is not activated, and the process directly returns to step S1. If the alarm device 23 is operating, the operation of the alarm device 23 is further canceled in step S10, and the process returns to step S1.

  If the home appliance is not used in the shelf A3 in step S6, the control circuit 22 returns to step S1. Then, the control circuit 22 repeats the operations of steps S1 to S10 described above.

In this way, when the user tries to close the shutter 16 when using home appliances, particularly home appliances that generate water vapor such as an electric rice cooker, the alarm device 23 is activated. Shutter closure can be avoided. Accordingly, it is possible to effectively prevent water vapor from accumulating, dew condensation or mold from being generated in the shelves A2 and A3 closed by the shutter.
In the household appliance storage cabinet 10 having such a configuration, the alarm device 23 may be configured to issue a warning for a predetermined time based on a control signal. Thereby, steps S4, S5, S9 and S10 in the flowchart of FIG. 6 described above can be omitted.

[Second Embodiment]
7 and 8 show the configuration of the second embodiment of the home appliance storage cabinet according to the present invention. In FIG. 7, the household appliance storage cabinet 30 is the structure substantially the same as the household appliance storage cabinet 10 shown in FIG. 1, Comprising: Only the following points differ. That is, the home appliance storage cabinet 30 includes a locking device 31 on each of the shelves A2 and A3, instead of the alarm device 20 in the home appliance storage cabinet 10 shown in FIG.

  As shown in FIG. 7, the locking device 31 is disposed at a position immediately below the shutter detection sensor 21 in the shelves A2 and A3, and advances and retreats in the passage of the shutter 16 guided by the guide grooves 11c and 11d. The stopper 32 is supported in a possible manner, and driving means 33 for inserting and removing the stopper 32 into and from the passage of the shutter 16. Each locking device 31 prevents the shutter 16 from closing (lowering) by inserting or retracting the stopper 32 into the passage of the shutter 16 by the driving means 33 based on a control signal from the control circuit 22. Or come to forgive.

  As shown in FIG. 8, the control circuit 22 in the present embodiment detects the shutters of the shelves A2 and A3 when the use of home appliances is detected by the power outlets 19a and 19b provided in the shelves A2 and A3. Based on the detection signal from the sensor 21, the locking device 31 of the shelves A1 and A3 is actuated to prevent the shutter 16 from closing. Here, the control circuit 22 checks the detection signal from the shutter detection sensor 21 before sending the control signal to each locking device 31, and controls only when the shutter opening in each shelf A2, A3 is confirmed. Send a signal.

  In the illustrated case, the driving means 33 includes a pinion 33a that is rotationally driven by a motor (not shown), and a rack 33b that reciprocates linearly by the rotation of the pinion 33a. The stopper 32 supported by the rack 33b is indicated by an arrow. Move back and forth in the direction.

  According to the household appliance storage cabinet 30 having such a configuration, like the household appliance cabinet 10 shown in FIGS. 1 and 2, the shutter 16 is normally opened, and the front surfaces of the respective shelves A1, A2, and A3 are opened. The inside is visible. For example, a microwave oven is stored in the shelf A2, and an electric kettle and an electric rice cooker are stored in the shelf A3. The power cords are connected to the power outlets 19a and 19b, respectively.

From this state, for example, when the power of the electric rice cooker is turned on, power is supplied from the power outlet 19b to the electric rice cooker via the control circuit 22, and the electric rice cooker operates. Then, the home appliance use sensor 19d senses the current of the power outlet 19b and detects the use of the home appliance, whereby the blower 7 starts operating.
Further, when the lower end 16b of the shutter 16 is moved downward, as shown in FIG. 3, the shutter 16 closes the shelves A1 to A3. The inside can be concealed.

Next, operation | movement of the shutter opening / closing control apparatus 20 of the household appliance storage cabinet 30 is demonstrated concretely according to the flowchart of FIG.
First, in step S11, the control circuit 22 checks the use of home appliances in the shelf A2 based on the detection signal from the home appliance use sensor 19c in the shelf A2.

When the home appliance is used in step S11, the control circuit 22 checks the shutter opening of the shelf A2 based on the detection signal of the shutter detection sensor 21 of the shelf A2 in step S12.
When the shutter of the shelf A2 is opened in step S12, the control circuit 22 operates the locking device 31 of the shelf A2 and enters the stopper 32 into the passage of the shutter 16 in step S13. This prevents the shutter 16 from closing, and then returns to step S11.

  If the shutter 16 is closed at step S12, the control circuit 22 determines that the shutter is closed at the shelf A2, stops the operation of the locking device 31 of the shelf A2, and returns to step S11 as it is.

If the home appliance on the shelf A2 is not used in step S11, the control circuit 22 confirms the operation of the stopper 32 of the locking device 31 on the shelf A2 in step S14. If the stopper 32 is operating, the operation of the stopper 32 is stopped and released in step S15. If the stopper 32 is not operating in step S14, step S15 is passed.
Subsequently, in step S16, the control circuit 22 checks the use of the home appliance on the shelf A3 based on the detection signal from the home appliance use sensor 19d on the shelf A3.

  When the home appliance is used in step S16, the control circuit 22 checks the shutter opening of the shelf A3 based on the detection signal of the shutter detection sensor 21 of the shelf A3 in step S17. If the shutter of the shelf A3 is opened in step S17, the control circuit 22 operates the locking device 31 of the shelf A3 in step S18 and returns to step S16. If the shutter 16 is closed in step S17, the control circuit 22 determines that the shutter is open on the shelf A3, and returns directly to step S11.

  If the home appliance on the shelf A3 is not used in step S16, the control circuit 22 confirms the operation of the stopper 32 of the locking device 31 on the shelf A2 in step S19. If the stopper 32 is operating, the control circuit 22 stops and releases the operation of the stopper 32 in step S20. If the stopper 32 is not actuated at step S19, the process directly returns to step S11. Then, the control circuit 22 repeats the operations of steps S11 to S20 described above.

  In this way, when using household appliances that generate water vapor such as electric rice cookers, for example, the locking device 31 forcibly prevents the shutters 16 in the shelves A2 and A3 from being closed. The user does not accidentally close the shutter 16. Accordingly, it is possible to effectively prevent water vapor due to the use of home appliances, condensation, or mold generation in the shelves A2 and A3 closed by the shutter.

  The present invention can be implemented in various forms without departing from the spirit of the present invention. For example, although the example which used the current sensor was shown as household appliance use sensor 19c, 19d in embodiment mentioned above, the temperature sensor or humidity sensor which detects the heat | fever and water vapor | steam which generate | occur | produce at the time of use of household appliances is utilized, and household appliances are used. By detecting a temperature increase due to heat generation of the product with a temperature sensor, or detecting a humidity increase due to water vapor generated with the use of the home appliance with a humidity sensor, the use of the home appliance can be detected.

  As the shutter closing avoidance means, any one of the alarm device 23 and the locking device 31 described above may be provided, but it is more effective if both the alarm device 23 and the locking device 31 are provided.

  In the embodiment, an example of a rack and a pinion is shown as the driving unit 33 of the locking device 31. However, any other configuration driving unit may be used as long as the stopper 32 can be reciprocated. For example, it is obvious that a linear drive means such as a solenoid, a plunger or a linear motor can be applied as the drive means 33.

Further, in the above-described embodiment, among the shelves A, the lowermost shelf A4 is configured as a storage shelf with a normal door, but is not limited thereto, and is generally employed in a system kitchen. You may comprise as storage shelves of arbitrary formats, such as a storage shelf with a drawer, and a storage shelf without a door.
Moreover, in embodiment mentioned above, it was set as the structure which detects the use of the household appliance in the some shelf of shelf A2, A3, and operates the alarm apparatus 23 and the latching device 31, However, either shelf A2 or shelf A3 It is good also as a structure which detects use of only a household appliance and operates the alarm apparatus 23 grade | etc.,.
