Description

  The present invention relates to a storage cabinet having an outlet for supplying electric power to an electrical device stored in a storage body.

  2. Description of the Related Art Conventionally, there is a storage cabinet in which an outlet is provided in a storage body having a door whose opening can be opened and closed so that electric power is supplied to an electrical device stored in the storage body. For example, Patent Document 1 is known as a storage cabinet having such a door.

  The storage cabinet shown in this Patent Document 1 is designed to cook rice and keep warm in a state where the rice cooker is stored in the storage body. The storage cabinet is provided with an outlet for supplying power to the rice cooker. In addition, a ventilator is provided, which automatically operates the ventilator when cooking with a rice cooker, and further operates to vent the steam by operating the ventilator for a certain period of time when the rice is cooked. Yes.

  However, in the above conventional example, even if the storage body becomes abnormal temperature due to a failure of the rice cooker or the ventilator, power is continuously supplied to the rice cooker, which is not preferable for safety.

  Therefore, the present inventor provides temperature detecting means for detecting the temperature inside the container in the process leading to the present invention, and controls to cut off the power supply from the outlet when the temperature detecting means detects an abnormal temperature. I thought. Even if it becomes abnormal temperature by this, safety can be secured, but, for example, when cooking is completed and the rice cooker is opened, the door is opened and the rice cooker lid is opened. Because a large amount of high-temperature steam is generated, a new problem arises that the temperature detection means detects that the high temperature in this case is abnormal and shuts off the power supply from the outlet, making it impossible to keep the rice cooker warm. Turned out to be.

This is not limited to the rice cooker as the electric device stored in the storage body, but the same problem occurs when storing an electric device that generates steam or hot air such as an electric kettle for boiling water or a coffee maker.
No. 7-22105

  The present invention has been invented in view of the above-described conventional problems, and when an abnormal temperature is reached when an electric device stored in a storage body is used with the door closed, it is automatically disconnected from the outlet. It is an object to provide a storage cabinet that can shut off the power supply and ensure safety, and that does not erroneously shut off the power supply from the outlet by erroneous detection when the lid is open. is there.

  In order to solve the above problems, the storage cabinet according to the present invention is provided with a door 6 that allows the opening 1 of the storage body 3 to be opened and closed, and detects the outlet 27 and the temperature in the storage body 3 in the storage body 3. Temperature detecting means 31 for shutting off the power supply from the outlet 27 when the temperature detecting means 31 detects a temperature equal to or higher than a predetermined temperature with the door 6 closed, and the door 6 is opened. In the state, the temperature detection means 31 is set so as not to cut off the power supply from the outlet 27 even if a temperature higher than a predetermined temperature set as an abnormal temperature is detected.

  With such a configuration, when the door 6 is closed and the inside of the housing 3 is not visible (or difficult to see), electric power is supplied from the outlet 27 to the electrical device 7 housed in the housing 3. 7 is used, even if the temperature becomes abnormal, the temperature detection means 31 detects the abnormal temperature and shuts off the power supply from the outlet 27 to ensure safety. On the other hand, even when a large amount of steam or hot air comes out when the lid of the electric device 7 (for example, a rice cooker, an electric kettle for hot water, a coffee maker, etc.) is opened with the door 6 open, It is possible to continue normal use of the electric device 7 by continuing to supply power from the outlet 27 without erroneously detecting this as abnormal.

  Further, a ventilation device 8 for ventilating the inside of the storage body 3 is provided in the storage body 3, and the ventilation device 8 is operated by detecting a temperature below a predetermined temperature set as the abnormal temperature by the temperature detection means 31. It is preferable to do.

  With such a configuration, when the temperature detecting means 31 detects a certain temperature equal to or lower than a predetermined temperature set as an abnormal temperature, the ventilation device 8 is automatically operated. Normal energization can be used by preventing the inside of the storage body 3 from rising to an abnormal temperature.

  Moreover, it is preferable that the temperature detection means 31 includes an infrared sensor 31 a for detecting the temperature inside the housing 3 and an exhaust temperature detection sensor 31 b for detecting the exhaust temperature inside the housing 3.

  When the temperature of the outer surface of the electrical device 7 in the housing 3 and the temperature in the housing 3 are detected by the infrared sensor 31a and the temperature of the outer surface of the electrical device 7 and the temperature in the housing 3 become abnormal temperatures, the outlet 27 The power supply from the outlet 27 is cut off to ensure safety, and the exhaust gas temperature is detected by the exhaust gas temperature detection sensor 31b. When the exhaust gas temperature becomes abnormal, the power supply from the outlet 27 is cut off to ensure the safety. Double safety can be ensured, and even if one fails, the other can ensure safety.

  As described above, the present invention cuts off the power supply from the outlet when the temperature detection means detects a temperature higher than a predetermined temperature with the door closed, and the temperature detection means when the door is open. The power supply from the outlet is not cut off even when a temperature exceeding the specified temperature set as an abnormal temperature is detected, so use electrical equipment stored in the storage body with the door closed. If the temperature becomes abnormal during operation, the power supply from the outlet can be automatically cut off to ensure safety, and when the lid is opened, the power supply from the outlet is mistakenly cut off by false detection. Therefore, it is easy to use when energizing and using the electrical equipment in the storage body.

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

  The storage body 3 constituting the main body of the storage cabinet A is formed by a box having an open front surface. In the embodiment shown in the accompanying drawings, as shown in FIGS. The storage body 3 whose front surface is the opening 1 is configured by combining the face plate 11 and the back plate 30 in a box shape and fixing them. A storage space is formed in the storage body 3 to form a storage portion 2, and the bottom plate 4 constituting the bottom of the storage portion 2 is moved forward from the front opening 1 through the bottom plate slide mechanism 12. It can be pulled out freely.

  As shown in FIG. 7, the bottom plate slide mechanism 12 includes a fixing rail portion 13 that is fixed to a lower side of the storage portion 2, i.e., slightly above the lower surface plate 11 on the inner surface of the left and right side plates 9. The intermediate rail portion 14 is slidably attached to the rail portion 13 in the front-rear direction, and the bottom plate-side rail portion 15 is slidably attached to the intermediate rail portion 14 in the front-rear direction. The bottom plate side rail portions 15 are fixed to the left and right end faces of the bottom plate 4, respectively. When the bottom plate 4 is pulled forward, the bottom plate side rail portion 15 slides forward with respect to the intermediate rail portion 14 and the intermediate rail portion 14 slides forward with respect to the fixing rail portion 13, thereby opening the bottom plate 4. The bottom plate side rail portion 15 slides and overlaps with respect to the intermediate rail portion 14 and the intermediate rail portion 14 overlaps the fixing rail portion 13 by pushing the bottom plate 4 forward. On the other hand, the bottom plate 4 can be positioned in the storage portion 2 by sliding backward and overlapping. Of course, the bottom plate slide mechanism 12 is not limited to the above example, and other various slide rail mechanisms can be adopted.

  The housing 3 is provided with a door 6 that allows the opening 1 of the housing 2 to be opened and closed.

  In the embodiment shown in the accompanying drawings, as shown in FIGS. 5 and 6, a small gap is formed between the bottom plate 4 and the bottom plate 11 in the storage body 3 with the bottom plate 4 stored in the storage portion 2. Therefore, the small gap is used as the door storage portion 5. A door 6 is housed in a door storage portion 5 below the bottom plate 4 via a door slide mechanism 16 so that the door 6 can be pulled out forward. In the embodiment shown in the accompanying drawings, as shown in FIGS. 7 and 8, the door slide mechanism 16 is fixed to the lower end portions of the inner surfaces of the left and right side plates 9 (that is, the position immediately below the fixing rail portion 13). The door slide rail 17 and the left and right both ends have rollers 18 fitted to the left and right door slide rails 17 so that they can run freely, and the rear end of the door 6 is pivotally attached to the left and right. It is comprised with the member 19. FIG.

  As shown in FIG. 8, the slide member 19 that is elongated in the left-right direction is formed with recesses 20 that open at least forward and downward at a plurality of locations including at least both left and right ends. The shaft portion 21 thus formed is erected, and a bearing portion 22 provided at the rear end portion of the door 6 is rotatably fitted into the shaft portion 21.

  As shown in FIG. 9, a rotation support portion 23 is provided at the rear end portion of the door 6, and the rotation support portion 23 has a protrusion 24 protruding from the back surface side of the door 6. The bearing portion 22 is configured by providing a hole 25 in the protrusion 24, and is exposed to the rear surface side of the door 6 at a position behind the protrusion 24 of the rotation support portion 23 (in FIG. A contact portion 26 is provided which is exposed in a state of protruding rearward from the back surface.

  The door 6 is pivotally attached to the slide member 19 by pivotally supporting the bearing portion 22 on the shaft portion 21 of the slide member 19, but the door 6 is turned sideways so as to be in a horizontal state. 9A, the contact portion 26 hits the lower surface of the slide member 19 so that the door 6 is held in a horizontal horizontal posture. Accordingly, by pushing the door 6 in a state where the door 6 is held in a horizontal horizontal posture in this way, the slide member 19 is moved rearward with respect to the door slide rail 17, and the door 6 is directly below the bottom plate 4. The sliding member 19 can be moved forward with respect to the door sliding rail 17 by pulling the door 6 in the stored state forward. The door 6 can be pulled out so as to jump out to the front of the storage body 3 as shown in 9 (a). With the door 6 being pulled out in this way, the door 6 is rotated and raised as shown in FIG. 9B, thereby closing the opening 1 on the front surface of the housing 3 as shown in FIGS. Thus, the storage portion 2 including the bottom plate 4 can be covered. When the door 6 is erected and the storage unit 2 is closed, means for maintaining the erected state of the door 6 and maintaining the closed state is provided. As means for maintaining the closed state of the door 6, for example, a known technique for maintaining the closed state of the door 6 such as a magnet or a roller catch can be applied.

  When the door 6 is opened, the door 6 can be stored in the door storage unit 5 by rotating the door 6 in the opposite direction to the horizontal position to push the door 6 backward.

  An outlet 27 is provided in the storage unit 2. In the embodiment shown in the accompanying drawings, the outlet 27 is provided on the back plate 30, but it may be provided at a site other than the back plate 30. Although not shown, the outlet 27 is connected to a power line wired to the building.

  A ventilation device 8 for ventilating the inside of the storage unit 2 is provided at the top of the storage body 3. An operation unit 28 and a ventilation outlet 29 for operating the ventilation device 8 are provided at the upper end of the front surface of the housing 3. In addition, you may provide the ventilation outlet 29 in parts other than a front surface.

  In the storage cabinet A of the present invention having the above-described configuration, when the electric device 7 is placed on the bottom plate 4 and stored in the storage portion 2, the plug at the tip of the cord led out from the electric device 7 is stored in the storage portion. 2 is connected to the outlet 27 provided to supply electric power to the electric device 7 so that the electric device 7 can be used to supply electric power when the electric device 7 is stored in the storage unit 2. Yes.

  The storage cabinet A of the present invention configured as described above opens the opening 1, pulls out the bottom plate 4, puts a storage item on the bottom plate 4, and stores the storage in the storage portion 2 by pushing the bottom plate 4. It can store things. Further, by closing the opening 1 with the door 6 as shown in FIG. 1 with the bottom plate 4 stored in the storage unit 2, the storage unit 2 and the stored items can be prevented from being exposed to the outside.

  Here, when the opening 1 is opened and the door 6 is housed in the door housing 5, the inside of the housing 2 can be seen from the opening 1, but when the bottom plate 4 is not pulled out, the door 6 is hidden by the bottom plate 4. It is not exposed to the outside and the appearance is good. In the state in which the door 6 is stored, or in the state in which the door 6 is pulled out in the horizontal position, as shown in FIG. 2, the bottom plate 4 is pulled out and the stored items are placed on the bottom plate 4, or The stored item placed on the bottom plate 4 is taken out, or when the stored item placed on the bottom plate 4 is a container or an electric device 7, the contents can be taken in and out of the container or the electric device Operation, maintenance, inspection, or opening and closing of the lid can be performed when the electric device 7 is a rice cooker or the like. When the bottom plate 4 is slid in and out in the state where the door 6 is housed or pulled out in the horizontal position, the bottom plate 4 and the storage object placed on the bottom plate 4 do not hit the door 6, and the bottom plate 4 can smoothly slide, and the bottom plate 4, the stored items, and the door 6 are not damaged by the collision.

  By the way, in the present invention, since the outlet 27 is provided, when the electric device 7 is placed as a stored item on the bottom plate 4 that can be pulled out and stored in the storage portion 2, the cord led out from the electric device 7 is stored. The plug at the tip is connected to an outlet 27 provided in the storage unit 2 to supply electric power to the electric device 7.

  Here, in the case where the stored item placed on the bottom plate 4 is an electric device 7 that generates steam or hot air such as a rice cooker or an electric kettle for boiling water, the rice cooker or kettle is heated in the storage unit 2 by operating the ventilator 8. Steam or hot air generated from an electric kettle, a coffee maker, or the like can be exhausted to the outside so that water vapor or hot air does not accumulate in the storage unit 2.

  In addition, by making the inner surface of the storage unit 2 a metal plate such as an iron plate, even if high-temperature steam is generated in the storage unit 2 or hot air is generated, the inner surface of the storage unit 2 is caused by water or heat from the steam. It is not attacked and can increase safety.

  For the same reason, by making the entire bottom plate 4 or at least the upper surface portion of the bottom plate 4 made of metal such as an iron plate, the bottom plate 4 is not affected by water or heat caused by steam, and safety can be improved.

  In the storage cabinet A of the present invention, the outlet 27 is provided in the storage unit 2 as described above. However, the electrical device 7 is stored as a storage item in the storage unit 2 and supplied with power from the outlet 27. A safety device as shown in the control block diagram of FIG. 3 is provided as a safety measure when the electrical equipment 7 is energized and used in the storage unit 2.

  The safety device includes a temperature detection unit 31, a door opening / closing detection unit 32 that detects opening / closing of the door 6, a control unit 33 that receives detection information from the temperature detection unit 31 and the door opening / closing detection unit 32, and the detection information. Power supply blocking means 34 for cutting off the power supply from the outlet 27 by the control signal output from the control unit 33 based on the temperature of the door 6 when the door opening / closing detection means 32 detects the closing of the door 6. When the detection means 31 detects a temperature that is equal to or higher than a predetermined temperature set in advance, the power supply cutoff means 34 cuts off the power supply from the outlet 27 so that no electric power is supplied to the electrical device 7. To be controlled. In the state in which the door opening / closing detection means 32 detects the opening of the door 6, the safety device can detect the power even if the temperature detection means 31 detects a temperature equal to or higher than a predetermined temperature set in advance. The supply of power from the outlet 27 is not blocked by the supply blocking means 34.

  As the door opening / closing detection means 32, for example, a magnet 32a is provided on the door 6 and a magnetic detection switch 32b is provided on the housing 3 side or on the ventilation device 8.

  In the embodiment shown in FIG. 3 as the temperature detection means 31, an infrared sensor 31 a that detects the outer surface temperature of the electrical equipment 7 that is stored in the storage unit 2 and the temperature in the storage unit 2, and the ventilation device 8. There is an exhaust temperature detection sensor 31b for detecting the exhaust temperature provided in the exhaust passage.

  In the above embodiment, in the state in which the door opening / closing detection means 32 detects the closing of the door 6, the infrared sensor 31 a detects the abnormal temperature in the outer surface of the electrical device 7 or the storage unit 2 (preset by the infrared sensor 31 a). When a certain set temperature is detected as an abnormal temperature), the power supply from the outlet 27 is stopped by the power supply cut-off means 34.

  The exhaust temperature detection sensor 31b detects not only the temperature detected by the infrared sensor 31a but also the exhaust temperature detection sensor 31b. When the door opening / closing detection means 32 detects the closing of the door 6, the exhaust temperature detection sensor 31b Even when an abnormal temperature of the exhaust gas is detected, the power supply interruption means 34 stops the power supply from the outlet 27. Therefore, even if the infrared sensor 31a fails, if the exhaust temperature becomes abnormal while the door opening / closing detection means 32 detects the closing of the door 6, the power supply interruption means 34 stops the power supply from the outlet 27.

  In the state where the door opening / closing detection means 32 detects the closing of the door 6 as described above, the power supply cutoff means 34 stops the power supply from the outlet 27 by detecting the abnormal temperature with the infrared sensor 31a. However, in addition to this, in the state in which the door opening / closing detection means 32 detects the closing of the door 6, when a predetermined temperature (ventilator operating temperature) lower than the abnormal temperature is detected by the infrared sensor 31a, The ventilator 8 is operated (the fan of the ventilator 8 is operated), thereby preventing abnormal temperature rise due to accumulation of steam or hot air in the storage unit 2.

  As for the operation of the ventilator 8, the ventilator 8 is operated when the infrared sensor 31a detects the ventilator operating temperature even when the door opening / closing detector 32 detects the opening of the door 6. May be.

  Even when the door 6 is closed with the above-described configuration, even when electric power is supplied from the outlet 27 to an electric device such as a rice cooker, an electric kettle for water heater, or a coffee maker disposed in the storage unit 2. The storage unit 2 is prevented from abnormally rising in temperature, and even if the storage temperature becomes abnormal, safety can be ensured by cutting off the power supply from the outlet 27. Therefore, it is possible to energize and use electric appliances such as a rice cooker, an electric kettle for boiling water, a coffee maker, etc. that emit steam, hot air, etc. when energized with the door 6 closed.

  On the other hand, in the state in which the door opening / closing detection means 32 detects the opening of the door 6, if the infrared sensor 31 a detects an abnormal temperature in the outer surface of the electrical device 7 or the storage unit 2, the exhaust temperature detection sensor 31 b In any case where an abnormal temperature is detected, power supply from the outlet 27 by the power interruption means 34 is not stopped.

  This is because, for example, when the electrical device 7 as a storage item is a rice cooker, the rice cooker is kept warm after the rice cooking is finished. At this stage, the door 6 is opened and the bottom plate 4 is attached as shown in FIG. When the rice cooker lid is pulled out and a large amount of water vapor is released, the infrared sensor 31a and the exhaust gas temperature detection sensor 31b are erroneously at abnormal temperatures even though the storage unit 2 and the electrical device 7 are not abnormal. If this is detected and power supply from the outlet 27 is stopped, there is a problem that power supply to the rice cooker for heat insulation is stopped. However, in the present invention, when the door 6 is in the open state as described above, the power supplied from the outlet 27 by the power supply shut-off means 34 in both cases where the infrared sensor 31a and the exhaust temperature detection sensor 31b detect abnormal temperatures. Since the supply is not stopped, the door 6 is opened, the bottom plate 4 is pulled out as shown in FIG. 2, the lid of the rice cooker is opened, and even if a large amount of steam is released, the power supply for heat insulation to the rice cooker is stopped. Will never be done.

  In the embodiment shown in the accompanying drawings, since the door storage portion 5 is provided below the pullable bottom plate 4 constituting the bottom of the storage portion 2, the bottom plate slide mechanism 12 required for pulling out the bottom plate 4 and The door slide mechanism 16 required for pulling out the door 6 can be arranged in the lower part of the storage unit 2, and the door slide mechanism 16 is provided on both the left and right sides of the storage unit 2 and on the upper side to separate from the storage position of the bottom plate 4. Compared with the case where the door 6 is housed in the place where the door 6 is housed, the effective use size in the left-right direction in the housing portion 2 can be increased, and other accessories are provided on the housing 3 without being obstructed by the door 6 or the rail member. Equipment can be arranged. Moreover, even if there is a wall next to the door 6 when the door 6 is opened or closed, there is no hindrance to opening or closing the door 6, and when another storage cabinet is located next to the door, the door can be opened even if there is a drawer in another cabinet. When opening and closing 6 and drawer operation of another cabinet next to it do not interfere with each other, there is no restriction on the position of the door 6 when opening and closing, and in combination with another storage cabinet Also, the restriction due to the opening and closing of the door 6 is eliminated. Further, since the door 6 is stored so as to overlap the lower position of the bottom plate 4 of the storage unit 2, in the case where the bottom plate 4 of the storage unit 2 can be pulled out freely, the storage body 3 is not affected by the storage and opening / closing of the door 6. It becomes possible to provide the ventilation apparatus 8 in the upper part of the.

  In the embodiment described above, an example in which the door storage portion 5 is provided at the lower end portion of the storage body 3, and the opening 1 is closed by pulling the door 6 stored in the door storage portion 5 toward the front and turning it. However, in the present invention, there are no particular limitations on the mounting position of the door 6, the opening / closing mode of the door 6, the presence / absence of the door storage portion 5, the position thereof, and the like. Of course, the open / close technique of No. 1 can be applied.
