Description

  The present invention relates to a storage unit having a push-open drawer.

  As means for storing the objects to be stored, there are means for moving the objects to be stored in a fixed shelf such as a cupboard or a closet, and a drawer such as a chest or a kitchen to slide the drawer to place the objects to be stored. And a means for storing the whole.

  In the latter storage means using the drawer, the storage object can be easily stored from above, and high space efficiency can be obtained by providing a plurality of drawers in parallel in the horizontal and vertical directions. For example, drawers in the kitchen can easily store large and small items to be stored from above, such as tableware such as bowls, dishes, cups, cooking utensils such as pots and pans, and seasonings such as salt and pepper. it can.

On the other hand, with the recent increase in added value and higher functionality, there is a demand for further ease of use and convenience of the storage unit. In view of this, a so-called push-open type storage unit has been proposed in which the drawer is automatically pulled out by simply pushing the front surface of the drawer front plate slightly back (for example, Patent Document 1). Such a push-open storage unit can be easily pulled out by bringing the back of the hand or a part other than the hand into contact with the drawer, thereby improving cooking efficiency.
International Publication WO2006 / 112189

  As an extrusion mechanism in the push-open type storage unit described above, a mechanical device using a spring and a latch, or an electric device using a motor can be used. The electric extrusion mechanism is superior in that a desired operation can be obtained more easily than a mechanical type because the pushing amount and the extrusion speed can be freely set.

  In the storage unit, there are many cases where a plurality of drawers are provided, and almost the same number of extrusion mechanisms as the number of drawers are required. If a power supply device that converts voltage from a commercial power source is provided for each extrusion mechanism, the extrusion mechanism is increased in size and the cost of the apparatus is increased. Therefore, one power supply device is provided for the entire storage unit.

  However, in particular, when the storage unit is a kitchen, the kitchen is composed of a plurality of cabinets (storages), and each cabinet has an independent configuration so that it can be rearranged according to the specifications of the kitchen. Therefore, it is necessary to wire the power supply across the plurality of cabinets from the power supply device. Here, if it connects using a connector etc., for example, there will be a problem that construction labor and parts costs increase and durability also decreases.

  In a kitchen, a cabinet provided with a sink requires piping for water supply and drainage, and a piping space for accommodating piping is provided. It is necessary to supply power in consideration of such a difference in the cabinet configuration.

  SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a storage unit in which a power cable is arranged at a uniform height regardless of the presence or absence of a piping space in a storage unit having a plurality of storages, thereby improving workability and durability. It is said.

  In order to solve the above-mentioned problems, a typical configuration of a storage unit according to the present invention is arranged in a drawer, a plurality of storages in which the drawers can be slidably stored, and at least one lower part of the plurality of storages. A piping space for accommodating the water supply / drainage piping, a piping plate for sealing the upper surface of the piping space, an extrusion mechanism for pushing out the drawer when the drawer is further pushed into the storage direction from a predetermined storage completion position, and a power supply device And a power cable for supplying power to the extrusion mechanism from the power supply device, the power cable being arranged through the plurality of storage boxes, and a branch cable branching from the main power cable to each extrusion mechanism The main power cable is arranged above the piping plate and in a substantially horizontal direction through a plurality of storages.

  According to the above configuration, in the storage unit having a plurality of storages, the main power cable can be arranged at a uniform height regardless of the presence or absence of the piping space. Even if the order of the storage is changed (rearranged), the main power cable can be penetrated (inserted) using the same hole. In addition, a hole can be provided in the cabinet in order to penetrate the main power cable in advance, and the main power cable can be installed as it is even when the cabinet is increased or decreased or the order is changed according to the specifications of the kitchen . From these things, workability and durability can be improved.

  The storage unit may be a kitchen, and the storage provided with the piping plate may be a storage provided with a sink. This is because a plurality of storages such as a stove cabinet and a sink cabinet are installed in the kitchen, and the sink cabinet is provided with a sink, a piping space, and a piping plate.

  It is preferable that a main power cable for supplying power to the extrusion mechanism from the power supply device is attached to the inner surface of the back plate of the storage. As a result, the main power cable can be installed in a plane along the back plate, and it is wired uniformly regardless of the type of cabinet regardless of the gas pipes and water supply / drainage pipes arranged on the back side inside the kitchen. It is possible to use the space efficiently while ensuring the storage capacity as much as possible.

  The extrusion mechanism may be electrically connected in parallel by a branch cable from the main power cable to each extrusion mechanism. Thereby, since an extrusion mechanism can be freely connected within each cabinet, workability can be improved.

  Preferably, the push-out mechanism recognizes the storage completion position in the drawer storage and detects the push-in from the drawer storage completion position based on the movement distance of the drawer. Accordingly, since the drawer is automatically pulled out by slightly pushing the drawer, the opening / closing of the drawer becomes very simple, and a high-class feeling can be obtained by automation.

  According to the present invention, in a storage unit having a plurality of storages, a power cable can be arranged at a uniform height regardless of the presence or absence of a piping space, thereby improving workability and durability.

  Embodiment of the storage unit concerning this invention is described using figures. In the present embodiment, the storage unit will be described using a system kitchen as an example. The dimensions, materials, and other specific numerical values shown in the following embodiments are merely examples for facilitating the understanding of the invention, and do not limit the present invention unless otherwise specified. Further, in the present specification and drawings, constituent elements having substantially the same functional configuration are denoted by the same reference numerals, and redundant description is omitted.

(overall structure)
FIG. 1 is a diagram illustrating the overall configuration of a system kitchen as an example of a storage unit. The kitchen 100 is a so-called face-to-face open system kitchen, and a top plate 110 (also referred to as a work top) is formed of a stainless material and covers the entire upper surface of the system kitchen. The top plate 110 may be formed using a synthetic resin material.

  On the top surface of the top plate 110, there are provided a stove 112 attached in a built-in manner, a cooking space 114, an integrally formed sink 116, and a preparation space 118. The cooking space 114 and the preparation space 118 are similarly flat table surfaces, but the cooking space 114 located between the sink 116 and the stove 112 is assumed to be a place where cooking is mainly performed, and is located outside the sink 116. The preparation space 118 is assumed to be an auxiliary place for temporarily placing food and cooking utensils.

  Below the top plate 110 is composed of a stove cabinet 120 in which a stove 112 is installed, a base cabinet 130 having a cooking space 114, a sink cabinet 140 in which a sink 116 is installed, and an auxiliary cabinet 150 having a preparation space 118. ing. Each cabinet functions as a storage, and an empty space in the cabinet accommodates wiring to the stove 112, a water supply / drain pipe to the sink 116 and the faucet, and the like.

  As described above, although the top plate 110 is continuous over the entire system kitchen 100, the cabinet corresponding to each configuration such as the sink 116 and the stove 112 on the top plate 110 is provided below the top plate 110. Are provided.

  As a result, even when the configuration of the system kitchen 100 is varied, it is only necessary to prepare parts such as a drawer and a front plate for each cabinet, and the production efficiency can be improved. Here, the configuration of the system kitchen includes, for example, the width of the cooking space 114 and the sink 116, the presence / absence of the preparation space 118, and the like.

  Each cabinet is provided with drawers of various sizes as storage in this embodiment. For example, the stove cabinet 120 includes a grill 112a of the stove 112 and an operation panel 112b at the top, and a spice box 122, which is a small drawer for storing small items such as seasonings, is disposed on both sides thereof. A large wide drawer 124 is arranged at the center of the stove cabinet 120, that is, below the grill 112a, so that a relatively large cooking utensil such as a pot or bowl can be accommodated. A drawer-type foot storage 126 is disposed near the floor below the stove cabinet 120.

  Similarly, the base cabinet 130 is provided with a plurality of relatively small drawers 132 and a foot storage 136, and the sink cabinet 140 has a drawer 144 with a high front plate extending from the foot storage 146 to the sink curtain 142. Is provided. The auxiliary cabinet 150 is provided with a drawer 152 having a high front plate extending from the foot storage 156 to the top plate 110, and an inside drawer 154 that can be taken in and out independently is provided therein.

(Extrusion mechanism)
FIG. 2 is a diagram illustrating the internal configuration of the cabinet. As shown in the figure, rails 204 for guiding drawers are provided on the wall plate 202 of each cabinet so as to be symmetrical. A drive unit 210 as an example of an extrusion mechanism that pushes out the drawer is provided on the back side of each drawer storage position (storage completion position).

  3A and 3B are diagrams illustrating the drive unit. FIG. 3A is a schematic perspective view of the drive unit, and FIG. 3B is a plan view illustrating the operation of the drive unit.

  As shown in FIG. 3A, the drive unit 210 includes a drive unit 212 and an arm 214 that cantileverly protrudes from the drive unit 212. The drive unit 212 is operated by electric power, and includes a motor that rotates the arm 214, an encoder that detects the amount of rotation of the arm 214, and a control unit that controls these encoders.

  As shown in FIG. 3B, when the drawer 124 is pulled out, the arm 214 of the drive unit 210 protrudes toward the drawer. When the drawer 124 is accommodated as shown in FIG. 3C, the arm 214 is pushed by the back surface of the drawer 124 and rotates. At this time, the drive unit 212 detects the rotation of the arm 214 by an encoder.

  A damper 330 is provided on the wall plate 202 of the cabinet, and when the front plate 302 of the drawer 124 abuts against the damper 330, a storage completion position (a position where the drawer 124 is completely stored) is defined. When the drawer 124 stops at the storage completion position, the control unit in the drive unit 212 recognizes the storage completion position from the amount of change per unit time of the encoder. As shown in FIG. 3D, when the drawer 124 is further pushed in from the storage completion position against the biasing force of the damper 330, the control unit detects this by the encoder and operates the motor in the drive unit 212. Then the arm 214 is rotated. As a result, as shown in FIG. 3 (e), the drawer 124 is pushed out in the opposite direction.

  With the above configuration and operation, for the user, the drawer comes out automatically by pushing the drawer slightly. Therefore, opening and closing of the drawer becomes very simple, and a high-class feeling can be obtained by automation. The amount to be pushed in can be set arbitrarily, but can be set to 1 mm or more, for example. Also, in order to avoid pushing out the drawer when leaning on the drawer, it will be pushed out only when the push is in a short time, and it will be pushed out if it has been pushed in for a predetermined time (for example, 2 seconds or more). Can be controlled so that there is no.

  When a large number of drawers 132 are provided as in the base cabinet 130, the drive unit 210 is attached to a vertical bracket 250 that is installed in the vertical direction and whose upper and lower ends are fixed. Further, when the width is wide for the stove cabinet 120 and when the depth position of the drawer is different as in the sink cabinet 140, it is attached to the horizontal bracket 260 that is installed in the horizontal direction and the left and right ends are fixed.

(Malfunction prevention mechanism: vibration switching device)
As shown in FIG. 2, the kitchen 100 includes an AC adapter 220 and a vibration opening / closing device 230 as power supply devices. The AC adapter 220 is a power conversion device that generates DC power supplied from the commercial AC power source to the drive unit 210. The vibration-sensing switch 230 is a switch that detects vibration and opens and closes the power supply circuit. For example, it is caused by vibration (swing) of the drawer due to an earthquake, shaking of the building, shaking of the kitchen body when the drawer is suddenly tightened It is a device that prevents malfunction.

  The vibration-sensing switch 230 includes a triaxial acceleration sensor for sensing vibration and a relay circuit for connecting / disconnecting the power supply circuit, and is arranged on the wiring between the AC adapter 220 and the drive unit. Is done. In the present embodiment, when a slight earthquake is detected by the acceleration sensor, the power supply is shut off for a predetermined time (for example, 2 seconds). When vibration continues, every time the acceleration sensor detects vibration, the power is shut off for a predetermined time from that point. A slight earthquake can be set to 20 gal to 50 gal, for example. This is a vibration that humans do not notice.

  As described above, the drive unit 210 performs the push-out operation by detecting that the drawer has been pushed in by 1 mm to 2 mm. In contrast, Japan has many earthquakes, and if the drawer is shaken by the earthquake, the drive unit 210 may misrecognize that the drawer has been pushed in and may push out the drawer. However, according to the above configuration, the swinging of the drawer due to the earthquake can be ignored, so that a malfunction can be prevented.

  Note that the vibration-sensing switch device 230 as a malfunction prevention device is made inoperable by cutting off the power supplied to the drive unit 210. Accordingly, when the vibration-sensing opening / closing device 230 is in operation, the drawer can be put in and out as if it were a normal drawer (without a drive unit). Furthermore, it is preferable to provide a known earthquake-resistant latch (a member that protrudes and cannot be pulled out by vibration) so that the drawer does not open due to the shaking in the event of an earthquake.

(Power supply arrangement)
Next, the arrangement of the power supply device will be described with reference to FIGS. FIG. 4 is a front view and a sectional view of the stove cabinet. As shown in the figure, the AC adapter 220 and vibration-sensing switchgear 230 as power supply devices, and the wiring of the power cable from these to the drive unit 210 are attached to the inner surface of the back plate of the cabinet.

  As described above, relatively thin objects such as power cables can be installed in a plane along the back plate, making it possible to arrange them uniformly regardless of the type of cabinet, and as much storage capacity as possible. While ensuring, the power supply device and the wiring could be arranged efficiently using the space.

  In the present embodiment, the power supply device is attached to the stove cabinet 120, but may be the base cabinet 130 or the auxiliary cabinet 150. However, since the sink cabinet 140 is not preferred to be covered with water in the event of water leakage, it is desirable to attach the power supply device to a cabinet that does not include a sink.

(Wiring the power cable)
Next, the wiring of the power cable from the power supply device to the drive unit will be described with reference to FIGS. 2 and 5. FIG. 5 is a front view and a sectional view for explaining wiring of the entire kitchen. The AC adapter 220 and the vibration switching device 230 as a power device are connected by a cable 240a, and the vibration switching device 230 is connected to the main power cable 240c by a cable 240b. The main power cable 240c passes through the wall plate 202 of each cabinet as shown in FIG. 5B, and is stretched over all the cabinets as shown in FIG. 5A. In each cabinet, the main power cable 240c is electrically connected to each drive unit 210 in parallel by a branch cable 240d to supply power.

  By the way, as shown in FIG.5 (b), the sink cabinet 140 is provided with the piping space 148 for accommodating piping of water supply / drainage near the floor surface of the lower part by the side of the backplate 206. As shown in FIG. The upper surface of the piping space 148 is sealed with a piping plate 149. When constructing piping for supplying water to the faucet or draining water from the sink, a hole or a notch is formed in the piping plate 149 to start up the piping. .

  Although it is not impossible to dispose the main power cable 240c in the piping space 148, it is not preferable to bring the electrical wiring close to the water in consideration of a water leak. Also, the piping plate 149 must be opened during wiring work, and care must be taken so as not to damage the electrical wiring during piping construction, resulting in poor workability.

  Therefore, in the present embodiment, even in a cabinet without the piping plate 149, the main power cable 240c is laid (wired) in a substantially horizontal direction with the height higher than the piping plate 149 of the sink cabinet 140. ing. Thereby, the main power cable 240c can be installed linearly. Moreover, since the position (height) of the hole for penetrating the main power cable 240c is constant, a hole can be provided in the cabinet in advance, and the number of cabinets can be increased or decreased according to the specifications of the kitchen 100 or the order can be changed. In this case, the main power cable 240c can be installed as it is.

  Although the main power cable 240c extends over a plurality of cabinets, the main power cable 240c is not connected by a connector or the like, and therefore has high workability and durability. Further, by connecting the branch cable 240d to an arbitrary position of the main power cable 240c, it is possible to improve the workability in that the extrusion mechanism can be freely connected in each cabinet.

  In addition, although many drive units 210 are provided as the whole kitchen, since the foot storage is provided, the average position is close to the lower part of the kitchen. On the other hand, if the total length of the branch cable 240d is shorter, the construction is easier and the cost can be reduced. Therefore, in the present embodiment, the height of the main power cable 240c is set low, and the total length of the branch cables 240d is shortened.

  Although the preferred embodiments of the present invention have been described above with reference to the accompanying drawings, it goes without saying that the present invention is not limited to such examples. It will be apparent to those skilled in the art that various changes and modifications can be made within the scope of the claims, and these are naturally within the technical scope of the present invention. Understood.

  The present invention can be used as a storage unit having a push-open type drawer.

It is a figure explaining the whole system kitchen composition as an example of a storage unit. It is a figure explaining the internal structure of a cabinet. It is a figure explaining a drive unit. It is the front view and sectional drawing of a stove cabinet. It is the front view and sectional drawing explaining wiring of the whole kitchen.
