Description

  The present invention relates to a home appliance storage that stores home appliances such as a microwave oven and an oven toaster.

  Conventionally, a home appliance storage that stores home appliances having a heat generating function such as a microwave oven or an oven toaster is known from Patent Document 1.

  The home appliance storage case shown in Patent Document 1 supplies power to a slide shelf on which the home appliance is placed, a storage unit that allows the slide shelf to be pulled out and stored therein, and a home appliance provided in the storage unit. A power supply opening / closing means for opening / closing power supply to the outlet and the home appliance is provided.

  In the energization opening / closing means in Patent Document 1, when the slide shelf is pulled out, the limit switch is turned on to energize the outlet, and when the slide shelf is stored, the limit switch is turned off and the energization to the outlet is interrupted. It is like that.

  However, the conventional example has the following problems because the limit switch is turned off at the same time as the slide shelf is stored to cut off the power supply to the outlet.

  For example, when the operation state of the home appliance is in the heating operation (for example, the electric power used is 1000 W during the heating operation), when the slide shelf is stored and the power supply to the home appliance is cut off at the same time, the slide shelf is inserted immediately after the slide shelf is stored. When it is pulled out again, a large current is turned on and off in a short time, an inrush current is generated, or hunting occurs in the circuit opening and closing means of the energization opening and closing means of the home appliance and home appliance storage, and the energization of the home appliance and home appliance storage The damage to the electric circuit parts of the opening / closing means is large and the durability is inferior.

In addition, during operation of the cooling fan after the operation state of the home appliance has finished the heating operation, the power supply to the home appliance is cut off at the same time that the slide shelf is stored, so the cooling fan operation is also stopped immediately, Waste heat cooling in the appliance is not performed, which causes serious adverse effects such as damage to the electrical components of the appliance. In addition, it takes time to cool down the waste heat in the storage unit, the heat effect on the surrounding storage components is large, and the usability of the entire home appliance storage is extremely poor.

  Hereinafter, the present invention will be described based on embodiments shown in the accompanying drawings.

  FIG. 1 shows a schematic configuration diagram of a home appliance storage 9 according to the present invention, and FIG. 2 shows a control block diagram.

  The home appliance storage case 9 includes a slide shelf 2 on which the home appliance 1 is placed, a storage unit 3 that pulls out the slide shelf 2 and stores it in a freely retractable manner, and a slide shelf storage detection means that detects the storage of the slide shelf 2. A ventilation structure provided with a power feeding unit 4 (typically an outlet) for supplying power to the home appliance 1 provided in the storage unit 3 and an exhaust fan 8 for exhausting the storage unit 3. Have.

  Further, the home appliance storage 9 is further provided with a use state detecting means 7 for detecting the operating state of the home appliance 1, an energization opening / closing means 5 for cutting off the energization of the home appliance 1, and a control means 6. It is.

  A slide rail 15 is provided at the bottom of the storage unit 3, and the slide shelf 2 is movable with respect to the storage unit 3 via the slide rail 15, whereby the slide shelf 2 is pulled out from the storage unit 3. And stored in the storage unit 3.

  In the present invention, the slide shelf storage detecting means for detecting the storage of the slide shelf 2 is further configured as a slide shelf storage / drawing detection means having a function of detecting the drawer of the slide shelf. In the following description, the slide shelf storage detection unit will be described by taking the slide shelf storage / drawer detection unit as an example.

  In the embodiment shown in the accompanying drawings, the storage / drawer detection means is configured to detect storage and withdrawal by detecting the position of the slide shelf by the slide shelf position detection means 11. FIG. 7 shows an embodiment of the slide shelf position detecting means 11, and a first magnet 11 a and a second magnet 11 b are provided at the front and rear of the slide shelf 2, respectively. This is an example in which the slide shelf position detecting means 11 is configured by providing the first magnetic switch 11c and the second magnetic switch 11d at the front of the moving range.

  In this embodiment, when the slide shelf 2 is stored in the storage unit 3, the storage state is detected by the first magnet 11a operating the first magnetic switch 11c in the vicinity of the first magnetic switch 11c, and the slide shelf 2 is detected. The first magnet 11a is separated from the first magnetic switch 11c and the second magnet switch 11d is actuated when the second magnet switch 11d is actuated so that the pull-out state is detected. It has become.

  In the embodiment shown in FIG. 7, the position of the slide shelf 2 is detected by the slide shelf position detection means 11 at two locations in the slide direction. In this embodiment, not only the fully retracted state and the fully pulled out state can be detected, but the second magnet 11b is close to the second magnetic switch 11d and the second magnetic switch 11d is turned on as shown in FIG. If the second magnet 11b is moved off from the second magnetic switch 11d by moving the slide shelf 2 in the storage direction from the state, that is, even if it is in the middle of the movement in the storage direction, “slide shelf 2 It may be considered that the storage has been detected, and the control described later may be executed. In this case, the control described later can be quickly performed even during the storage, and the control described later can be executed even when the slide shelf 2 is not completely stored.

  Further, as shown in FIG. 7, the slide shelf 2 is not limited to an example in which the magnetic switch and the magnet are close to each other in a state where the slide shelf 2 is completely stored in the storage unit 3 and is completely pulled out. You may make it detect the said storing and drawer | drawing-out in the arbitrary arbitrary positions between the state stored in the accommodating part 3, and the state pulled out completely. For example, it may be detected that only half of the slide shelf 2 is stored and regarded as stored.

  The use state detection means 7 is for detecting which stage of the plurality of driving stages the home appliance 1 at the time when the slide shelf 2 is stored. As the use state detection means 7, for example, an energization current (power) detection means 12 for detecting a current (power) supplied to the home appliance 1, a temperature in the storage unit 3, or a temperature (surface temperature) of the home appliance 1. There are stored object detection means 10 such as a proximity sensor for detecting whether or not there is a stored object such as the home appliance 1 in the storage unit 3, and the use state detecting means 7 is a detection unit 7. For example, when the energizing current (power) detecting means 12, the temperature detecting means 13, and the stored object detecting means 10 are used, when the energizing current (power) detecting means 12 and the stored object detecting means 10 are used, the temperature detecting means 13 is used. Of the energized current (power) detecting means 12 and the temperature detecting means 13, and the energizing current (power) detecting means 12, the temperature detecting means 13, or the stored object detecting means 10. And a case of using one or misalignment.

  In the embodiment shown in FIG. 1, the temperature detection means 13 is configured by an object surface temperature detection sensor using infrared rays for detecting the surface temperature of the home appliance 1. The temperature detection means 13 for detecting the surface temperature of the home appliance 1 is provided on the ceiling portion of the storage unit 3, and the slide unit 2 is stored in either the retracted state or the pulled out state. The detection area is set so that the surface temperature of the home appliance 1 placed on the slide shelf 2 can be detected by the temperature detection means 13 provided on the ceiling.

  The energization current (power) detection means 12 detects the current (power) before and after the slide shelf 2 is pulled out and stored by, for example, an outlet circuit of an outlet that is the power supply unit 4.

  The home appliance 1 placed on the slide shelf 2 and stored in the storage unit 3 is provided with a heating function such as a microwave oven or an oven toaster.

  When using the home appliance 1 placed on the slide shelf 2 and stored in the storage unit 3 of the home appliance storage 9, the home appliance 1 is used by pulling out the slide shelf 2 and energizing the home appliance 1. To do. In addition, when the home appliance 1 is not in use, the slide shelf 2 is stored so that the home appliance 1 is stored in the storage unit 3.

  Here, in the present invention, when the slide shelf 2 is stored, the energization to the home appliance 1 is maintained depending on the operation state of the home appliance 1 or the slide shelf 2 is stored to cut off the energization to the home appliance 1. The energization opening / closing means 5 is controlled by the control means 6 so as to be performed with a delay from the time point.

  The opening / closing control of energization to the home appliance 1 by the energization opening / closing means 5 performed in this way is determined by the detection result of the operating state of the home appliance 1 by the use state detection means 7.

  3 to 6 show an embodiment of a specific control example. In this embodiment, it is an example in case the household appliances 1 provided with the cooling fan 14 have a heating operation state, a heat retention / cooling state, a standby state, and a non-energized state. Here, in the present embodiment, the heat insulation / cooling state and the standby state are both non-heating operation states.

  In this example, the electric power Wh in the heating operation state is, for example, 000 W, the electric power Wm in the heat insulation / cooling state is, for example, 20 W, the electric power Wl in the standby state is, for example, 2 W, and the electric power Wo in the off / non-energized state is This is the case for 0 W.

  That is, in this example, the current value correlated with the operation state of the home appliance 1 is “high” in the heating operation state, “low” in the heat insulation / cooling state, “fine” in the standby state, "Zero".

  FIG. 3 shows a control flow diagram of the basic control of the present embodiment.

  As shown in FIG. 3, the current value of the energization current (power) to the home appliance 2 by the energization current (power) detection means 12 is constantly monitored to monitor the state, and based on the detection of the current value. Then, the state determination of the home appliance 1 is performed. Here, the recognition of the state determination (for example, as described above, the heating operation state, the heat insulation / cooling state, the standby state, the off / non-energized state (that is, the current value is high, low, fine, zero) Since the value is different depending on 1, the control means 6 learns and stores the fact that there is such a stage, and recognizes which of the above-mentioned stages.

  At the start of use, even if the current value is “high”, “low”, “fine”, or “zero”, the temperature in the storage unit 3 or the temperature of the home appliance 1 is changed by the temperature detection means 13. When “high” is detected, regardless of whether the position of the slide shelf 2 is “drawer”, “storage”, or “intermediate position”, the stored item detection means 10 detects the stored item. Regardless of the presence or absence, the exhaust fan 8 is turned on, the energization is cut off by the energization opening / closing means 5, and the energization interruption is notified by the notification means 16 described later. That is, at the start of use, if the temperature in the storage unit 3 or the temperature of the home appliance 1 is detected as “high”, the mode shifts to safety control in any mode and immediately energizes.

  In addition, the current value is detected as “high” at the start of use, and the temperature in the storage unit 3 or the surface temperature of the home appliance 1 is “medium (˜T1)”, “low (˜T0)”, or “room temperature”. If the stored item is detected as “present” regardless of whether the position of the slide shelf 2 is “drawer”, “storage”, or “intermediate position” It becomes driving. If the stored item is detected as “nothing”, it is considered that the power supply unit 4 provided in the home appliance storage 9 is used as a power source for the home appliance 1 installed in a place other than the home appliance storage 9.

  Further, when the light load is used, it is detected that the current value is any one of “low”, “fine”, and “zero”, and the temperature in the storage unit 3 or the surface temperature of the home appliance 1 is “medium (˜T1)”. , “Low (˜T0)” or “room temperature” is detected, regardless of whether the position of the slide shelf 2 is “drawer”, “storage”, or “intermediate position”. If the stored item is detected as “existing”, it is regarded as a light load operation such as heat insulation, and if the stored item is detected as “none”, the home appliance installed in a place other than the home appliance storage 9 It is assumed that the power supply unit 4 provided in the home appliance storage 9 is used as a power source for the appliance 1.

  In the control flow of FIG. 3, during normal operation, the current value is detected as “high”, the temperature in the storage unit 3 or the surface temperature of the home appliance 1 is detected as “high”, and the slide shelf 2 is “stored”. If it is detected and the stored item is detected as “present”, the exhaust fan 8 is turned on, the energization switching means 5 performs the energization interruption, and the energization interruption is notified by the notification means 16 described later. In this case, the exhaust fan 8 is turned off when the temperature in the storage unit 3 or the surface temperature of the home appliance 1 reaches a safe temperature (for example, T0).

  On the other hand, during normal operation, it is detected that the current value is any one of “low”, “fine”, and “zero”, and the temperature in the storage unit 3 or the surface temperature of the home appliance 1 is “medium (˜T1)”. , “Low (˜T0)” or “room temperature”, the slide shelf 2 is detected as “stored”, and the stored item is detected as “present”, the slide shelf 2 by the user is detected. Is detected and the process proceeds to the end control.

  When shifting to the end control, the temperature in the storage unit 3 or the surface temperature of the home appliance 1 may be temporarily “high”.

  As described above, when the temperature in the storage unit 3 or the surface temperature of the home appliance 1 is detected as “high” in the termination control, the exhaust fan 8 is turned on. In this termination control, When it is detected that the temperature or the surface temperature of the home appliance 1 is “medium (to T1)”, “low (to) T0”, or “room temperature”, the exhaust fan 8 is turned off and the energization is cut off. Or return to the start of use without turning off the power.

  FIG. 4 shows a time chart when the home appliance 1 is energized and stored in the heating operation state at 1000 W during the normal operation in the control flow shown in FIG.

  That is, when the slide shelf 2 on which the home appliance 1 in the heating operation is placed in the storage unit 3 while the home appliance 1 is in the heating operation during the normal operation, the current value at the time of storage is “high” (that is, the home appliance). It is detected that the operation state of the appliance 1 is the heating operation state). When it is detected that the current value at the time of storing in this way is “high”, the temperature in the storage unit 3 or the surface temperature of the home appliance 1 (the surface temperature of the home appliance 1 in the solid line in FIG. 3) is “ In this case, as shown by the solid line in FIG. 4, the energization opening / closing means energizes the home appliance 1 from the power supply unit 4 with a delay of a predetermined time t1 from the time of storage as shown by the solid line in FIG. 5 forcibly shuts off.

  Thus, when the slide shelf 2 is stored in the heating operation state of the home appliance 1, the home appliance 1 is controlled so that the energization interruption to the home appliance 1 is delayed from the time when the slide shelf 2 is stored. Even if the slide shelf 2 is pulled out immediately after the slide shelf 2 is stored while the appliance 1 is in the heating operation state, the power supply to the home appliance 1 is not cut off immediately after the slide shelf 2 is stored as described above. The forced stop and the heating operation start during the heating operation with high power are not repeated in a short time, and it is possible to avoid stress on the electronic component of the home appliance 1.

  Further, when the slide shelf 2 on which the household appliance 1 in the heating operation state is placed is stored, since the surface temperature of the household appliance 1 exceeds a certain set temperature T1, the slide shelf 2 is stored as shown in FIG. At the same time, the operation of the exhaust fan 8 is started to exhaust hot air in the storage unit 3 from the exhaust port 18, and outside air is sucked into the storage unit 3 from the front opening of the storage unit 3 to reduce the temperature of the home appliance 1. At the same time, the temperature in the storage unit 3 is also lowered. In the embodiment, the operation of the exhaust fan 8 is stopped when the surface temperature of the home appliance 1 becomes equal to or lower than a predetermined temperature that is a safe temperature (for example, 40 ° C. that is the surface temperature To of the home appliance 1 in the standby state).

  Thus, by operating the exhaust fan 8, the temperature of the home appliance 1 stored in the storage unit 3 can be quickly made lower than the predetermined temperature, which is a safe temperature, and at the same time, the temperature in the storage unit 3 can be lowered to be lower than the safe temperature. And

  In the description of FIG. 4, the temperature detection unit 13 detects the surface temperature of the home appliance 1, and the above-described control is performed based on the detection result by the temperature detection unit 13. Thus, the above control may be performed by detecting the temperature in the storage unit 3.

  In the time chart of FIG. 4, a two-dot chain line indicates a change in temperature (atmosphere temperature) in the storage unit 3 when the slide shelf 2 on which the home appliance 1 in the heating operation state is placed is stored. You may make it perform the said control based on the change of the temperature in this accommodating part 3. FIG.

  Moreover, the broken line in the time chart shown in FIG. 4 shows an example in the case where the exhaust fan 8 is not provided. Thus, the absence of the exhaust fan 8 is not preferable because the temperature drop of the home appliance 1 and the storage unit 3 is extremely gradual even after the energization is cut off, and unsafe problems due to high temperatures continue for a long time.

  In FIG. 5, during normal operation in the control flow shown in FIG. 3, electricity is applied with the household appliance 1 pulled out, for example, heating operation (for example, 1000 W operation) ends, and then the cooling fan 14 is operated. The time chart when the slide shelf 2 is stored in the storage unit 3 during the cooling operation state (for example, 20 W operation) is shown.

  That is, when the home appliance 1 is stored during the cooling operation state during normal operation, the current value at the time of storage is detected as “low”.

  Even if it is detected that the current value at the time of storing is “low” in this way, the temperature in the storage unit 3 or the surface temperature of the home appliance 1 may be detected as “high” by the temperature detection means 13. . FIG. 5 shows an example in which the surface temperature of the home appliance 1 exceeds a certain set temperature T1.

  In this case, the exhaust fan 8 is operated when it is detected that T1 is exceeded after storage (simultaneously with storage in FIG. 5), and the temperature in the storage unit 3 or the surface temperature of the home appliance 1 is detected by the temperature detection means 13. Is turned off when the temperature reaches a safe temperature (for example, T0).

  Further, in FIG. 5, when the operation state of the home appliance 1 at the time when the slide shelf 2 is stored is detected by the current (power) detected by the energization current (power) detection unit 12, As shown in the time chart of FIG. 5, when the temperature in the storage unit 3 or the surface temperature of the home appliance 1 is equal to or lower than a predetermined temperature that is a safe temperature (for example, 40 ° C. that is the temperature To), the home appliance 1 Although an example is shown in which the energization is forcibly interrupted, as described in the control flow of FIG. 3, in this case, the standby state may be continued without interrupting the energization. . In other words, in this case, the current-carrying-off time to the home appliance is controlled to be ∞ from the time when the slide shelf 2 is stored, and the small current continues to be energized in the standby state without being cut off. To do.

  In FIG. 6, the slide shelf 2 is stored in the storage unit 3 when the operation of the cooling fan 14 is finished during the normal operation in the control flow shown in FIG. 3 and is in a standby state (for example, 2 W operation). A time chart is shown in the case of.

  In FIG. 6, since the temperature in the storage unit 3 at the time when the slide shelf 2 is stored is equal to or lower than a predetermined temperature that is a safe temperature (for example, 40 ° C. that is the temperature To in the storage unit 3 in the standby state). Even if the shelf 2 is stored, the exhaust fan 8 does not operate.

  3 thru | or FIG. 6, although demonstrated with respect to the household appliances storage 9 which accommodates the household appliances 1 with a heating driving | running state, a heat retention / cooling state, a standby state, and the state which is not turned off and energized, The present invention includes a home appliance 1 having a heating operation state, a heat retaining / cooling state, a state where no power is turned off, a heating operation state, a standby state, a home appliance 1 having a state where the power is not turned on, a heating operation state, The present invention can also be applied to home appliances that are not energized.

  The stored object detection means 10 is not limited to the above example. For example, the stored object detection may be performed by detecting the weight of the shelf surface of the slide shelf 2.

  In the case where the position of the slide shelf 2 is detected at two positions in the slide direction by the slide shelf position detection means 11 as in the embodiment shown in FIG. 7, the slide shelf 2 is stored and pulled out with a simple configuration. Recognition can be performed reliably, and the notification means 16 notifies when the energization of the home appliance 1 is cut off after the slide shelf 2 is stored, or when the slide shelf 2 is pulled out again, the notification means 16 cuts off the energization. It becomes easy to notify that the state is continued. Further, in the present embodiment, it is possible to add convenience of use such as continuing energization with a slight movement of the slide shelf 2 at the drawer position.

  In particular, in the case where the slide shelf 2 is regarded as being stored by detecting that the slide shelf 2 is in the intermediate position, the movement of the slide shelf 2 can be detected quickly, and the high-temperature home appliance 1 has moved to the storage unit 3 side. This can be detected quickly, and when the energization is interrupted after the slide shelf 2 is stored, or when the slide shelf 2 is pulled out again, the energization by the notifying unit 16 continues to be interrupted. It is possible to speed up the notification that there is, and it is possible to speed up the start of operation of the exhaust fan 8. Even if the home appliance 1 is operated with the slide shelf 2 slightly pulled out, the above-described safety control can be performed.

  In addition, in this embodiment, although the cooking appliances provided with the heat generating means are mounted on the slide shelf 2 and are used as safety protection means when the slide shelf 2 is stored in the storage unit 3, a juicer mixer or an electric cleaning device is used. Even if the power plug is left plugged into the outlet when storing household appliances that have rotation or cooling means such as a machine or electric dehumidifier, all energization is performed for a certain period of time or after a certain operating state has elapsed. It is possible to shut off, and it is possible to provide a safe storage state while leaving convenience in use, which is preferable.
