Description

  The present invention relates to a drawer-type mobile storage device or a lift-type mobile storage device used in, for example, a built-in dishwasher installed in a system kitchen, and in particular, can be easily taken out when taking out stored items. It is a movable storage device.

  Conventional mobile storage devices are used, for example, in high-level storage shelves in a residential environment, built-in drawer-type dishwashers installed below a system kitchen, and the like. First, in a residential environment, there are cases where storage shelves are installed in high places in order to effectively use empty spaces in high places. In storing and taking out from the storage shelf, the storage shelf is linked to the movement of the storage shelf and moved in an oblique direction of the opening to improve operability when storing and taking out the stored items (see, for example, Patent Document 1).

  Moreover, in the built-in type drawer-type dishwasher installed in the lower part of the system kitchen, the height of the dish basket becomes lower than in the case of being installed in the upper part. Thereby, when storing and taking out tableware in the tableware basket, the user needs to bend down and the operability becomes very poor. Therefore, the cleaning tank is pulled out by using an elevating device using a hydraulic cylinder (see, for example, Patent Document 2), or using an assist mechanism by a biasing force by a link mechanism and a spring (see, for example, Patent Document 3). The tableware basket is raised and lowered to improve operability when storing and taking out tableware.

  As described above, the conventional mobile storage device has a problem in that the empty space in the high place cannot be effectively used because the door and the drawer of the storage shelf operate in an oblique direction of the opening of the storage shelf. Further, after the cleaning tank as the drawer body is pulled out, the tableware basket as the storage body installed in the cleaning tank is moved in the opening direction. Therefore, operations (lever operation, switch pressing, etc.) other than the drawer and storage operation of the cleaning tank are required. As a result, there is a problem that the number of operations increases and the operability deteriorates. Furthermore, there is a problem that the tableware basket may be damaged because the tableware basket is forgotten to be stored in the cleaning tank and the cleaning tank is stored incorrectly. Therefore, there is a problem that the mechanism and control for preventing the erroneous operation are indispensable and the cost is increased.

  The present invention has been made to solve the above-described problems, and an object of the present invention is to obtain a mobile storage device with good operability.

The present invention includes an outer body having a storage port that is open in one direction, a moving body that has an opening in a direction substantially perpendicular to the direction of the storage port, and that moves so as to be able to enter and exit from the storage port.

Driving means capable of respectively moving the storage body in the inner and outer directions with respect to the opening;
Control means for controlling the drive means to operate in the outward direction for the moving movement of the moving body and the inward direction for the storage movement of the moving body,
The rail moves while the other end of the second link mechanism slides on the rail, and when the other end of the second link mechanism reaches the vicinity of the storage port, the first link mechanism moves outward and When the other end of the second link mechanism is separated from the storage port, the first link mechanism is moved inward.

The mobile storage device of the present invention includes an outer body having a storage port that is open in one direction, a moving body that has an opening in a direction substantially perpendicular to the direction of the storage port, and moves in and out of the outer body from the storage port. In a mobile storage device comprising a storage body that is stored from an opening in a mobile body and stores storage items,

  In the first embodiment, in the system kitchen, a drawer-type dishwasher as a mobile storage device disposed under the sink 1 is shown as an example. In the figure, an outer body 3 having a storage port 3a opened in one direction below the sink 1, and an opening 2a in a direction substantially perpendicular to the direction of the storage port 3a, and entering and exiting from the storage port 3a. The cleaning tank 2 is a movable body that can be moved, and the tableware basket 6 is stored in the cleaning tank 2 through the opening 2a and stores, for example, tableware. The tableware basket 6 is configured to be movable in an outward direction (upward in the drawing) and an inward direction (downward in the drawing) by the configuration described later.

  Then, in the gap between the outer body 3 and the cleaning tank 2 in the moving direction of the cleaning tank 2 (left-right direction in the figure), the cleaning tank 2 is pulled out from the outer body 3 (left direction in the figure) or outside A slide rail 40 capable of storing the cleaning tank 2 in the body 3 (rightward in the figure) is formed on the inner wall of the outer body 3 in a horizontal direction with respect to the moving direction. A sliding portion 41 that slides and moves on the slide rail 40 is formed. Next, a guide rail 5 as a rail is formed in the lower part of the slide rail 40 on the inner wall of the outer body 3 with respect to the moving direction of the cleaning tank 2. The guide rail 5 has a first horizontal groove 5a as a horizontal groove formed horizontally with respect to the moving direction from the rear of the storage port 1a, and a first horizontal groove 5a communicating with the first horizontal groove 5a. And a second horizontal groove portion 5c formed in a horizontal direction with respect to the moving direction in communication with the inclined groove portion 5b.

  Next, the tableware basket 6 has a tableware basket receiving portion 6a formed near the center in the height direction of the four corners of the tableware basket 6. Moreover, the receiving part 11 which can move up and down along the inner wall of the washing tank 2, and supports the tableware basket receiving part 6a is formed in the horizontal direction with respect to the moving direction. A groove 11a is formed in front of the groove 11a in the horizontal direction with respect to the moving direction. The receiving portion 11 is supported by driving means described later, and is moved up and down by the driving means. Further, a guide portion 10 is formed which is fixed to the lower front side of the inner wall of the cleaning tank 2 and has a groove portion 10a formed in a horizontal direction with respect to the moving direction.

  Next, the first link has a degree of freedom only in the outer and inner directions, that is, in the vertical direction with respect to the opening 2a, supports the tableware basket 6 via the receiving portion 11, and can move the tableware basket 6 in the vertical direction A mechanism 120 is provided. The first link mechanism 120 is composed of two links 121 and 122 of an X member whose central part is connected by a rotation shaft 123. These links 121 and 122 are rotatably connected by a rotating shaft 123. One link 122 is arranged such that the front end 122a is engaged with the groove 11a of the receiving portion 11 and slides back and forth with respect to the moving direction, and the rear end 122b passes the cleaning tank 2 from the inside to the outside. The link 122 is formed to be rotatable around the rear end 122b (rotary axis). The rear end portion 122b and the cleaning tank 2 have a known sealing structure using an O-ring or the like, and prevent water leakage from the inside to the outside of the cleaning tank 2.

  The other link 121 is arranged so that the front end 121b is engaged with the groove 10a of the guide member 10 and slides in the moving direction, and the rear end 121a is slid in one place on the receiving portion 11. It is arranged to do. The first link mechanism 120 is configured as described above, and by rotating the rotating shaft that is the rear end portion 122b of the link 122, the receiving portion 11 has a degree of freedom in the vertical direction while keeping the tableware basket 6 parallel. It can be moved up and down. One end portion of the second link mechanism 14 that is rotationally restrained or rotationally free with respect to the other end portion 122b (rotary shaft) via a clutch (not shown) outside the cleaning tank 2 of the rear end portion 122b (rotary shaft). Is connected. The clutch here can be formed with a known structure such as a magnetic fluid and an electromagnet. The other end portion 14a of the second link mechanism 14 is a rotary slide body and is rotatably connected. The second link mechanism 14 is engaged with the guide rail 5, slides along the shape of each groove portion, and moves in the front-rear direction.

  Next, the tableware basket receiving portion 6 a of the tableware basket 6 is supported by a plurality of driving means 7 that can move in the vertical direction via the receiving portion 11. The driving means 7 and the receiving portion 11 are formed so that their relative positions are substantially restrained in the horizontal plane and the vertical direction. For example, a known configuration such as a pin and pin hole structure can be used for restraining in the horizontal plane, and a one-push lock mechanism can be used for restraining in the vertical direction. As a result, the vertical assist force generated by the plurality of driving means 7 acts on the tableware basket receiving portion 6a via the receiving portion 11, and the tableware basket 6 moves up and down together with the driving means 7.

  Here, an example is shown in which the driving means 7 are installed at the four corners in the cleaning tank 2 and installed in a total of four locations. However, if the total assist force is a desired magnitude, the number of installation locations and the installation locations are shown. Is optional. The driving means 7 uses a hydraulic cylinder capable of using tap water. At this time, all the drive means 7 may be configured as a double-acting hydraulic cylinder capable of generating a force in the vertical direction, or configured so as to generate a force in the vertical direction using a plurality of single-acting hydraulic cylinders. It doesn't matter. Further, a water supply / drainage pipe 8 is connected to each driving means 7 from the lower outer side of the cleaning tank 2. The other end of each of the water supply / drainage pipes 8 is connected to water and sewers (not shown). And the solenoid valve 9 which controls the water supply / drainage of each of these water supply / drainage pipes 8 is connected, respectively. By controlling the opening and closing of each electromagnetic valve 9, the water supply or drainage to the driving means 7 is controlled, and the vertical assist force to the tableware basket 6 is controlled. Each electromagnetic valve 9 functions as a control means for controlling the drive means 7 to operate upward in the drawer movement of the cleaning tank 2 and downward in the storage movement of the cleaning tank 2.

  The resultant force of the upward assisting force in the driving means 7 is desirably about the resultant force of the maximum weight of the tableware basket 6 and the tableware stored in the tableware basket 6. When this assist force is small, the user's operation force required for pulling out the washing tank 2 during the lifting / lowering operation of the tableware basket 6 increases, and the operability deteriorates. On the other hand, the resultant force of the downward assist force in the drive means 7 does not need to be as great as the upward assist force. This is because a downward force always acts on the tableware basket 6 by its own weight. And the amount of tap water for maintaining the rising position present in the drive means 7 is small, and the time for draining it is sufficiently fast, and the drive means 7 can descend to the lowest position together with this drainage. That is, the downward assist force plays a role of reliably lowering the tableware basket 6 against the static frictional force of the driving means 7. Thereby, the tableware basket 6 can be reliably lowered at the time of the storing operation of the washing tub 2. However, since the rapid lowering operation of the driving means 7 may damage dishes or the like, the maximum value of the drainage pipe diameter is determined so that the lowering speed is lower than the desired speed.

  Next, a rotary shower head 16 that can rotate with washing water pressurized by a washing pump (not shown) is disposed at the bottom of the washing tank 2. A plurality of jets 17 are present on the upper part of the rotary shower head 16, and the tableware (not shown) installed in the tableware basket 6 is cleaned by spraying cleaning water upward. Here, when cleaning tableware, the upper opening of the cleaning tank 2 is sealed by a lid structure (not shown). In addition, there is an operation panel (not shown) in the vicinity of the upper part of the front surface of the washing tub 2, and an operator operates the operation of the dishwasher. In addition, using the operation unit 18 formed on the front surface of the cleaning tank 2, the user performs an operation of storing and pulling out the cleaning tank 2.

  Next, based on FIG. 4, the structure near the front surface of the cleaning tank 2 that performs the drawer operation and the storage operation will be described. The operation unit 18 is fixed via a front member 21 and a decorative plate 20 formed on the front surface of the cleaning tank 2. The operation unit 18 is operable in the front-rear direction with respect to the decorative plate 20 and the front member 21 via the operation rod 24. The amount of movement of the operation of the operation unit 18 with respect to the decorative plate 20 and the front member 21 is limited by the lower compression spring 23 sandwiched between the front member 21 via the operation movable member 22. On the other hand, the operation amount of the operation portion 18 with respect to the decorative plate 20 and the front member 21 is limited by the upper compression spring 25 installed between the rear portion 24 a of the operation rod 24 and the operation movable member 22.

  Further, a front detection sensor 26 and a rear detection sensor 27 are formed near the tip of the rear portion 24a of the operation rod 24 as detection means for detecting the operation state, that is, the drawer movement state and the storage movement state of the cleaning tank 2. . For each of the detection sensors 26 and 27, a known technique such as a general-purpose touch sensor, a pressure-sensitive sensor, or a non-contact sensor can be used. The electromagnetic valve 9 is configured so that the driving means 7 generates an upward force when the front detection sensor 26 is ON, and the driving means 7 generates a downward force when the rear detection sensor 27 is ON. To control. When both detection sensors 26 and 27 are OFF, each solenoid valve 9 is closed and the position of each drive means 7 is fixed.

  Next, a drawing operation and a storing operation of the drawer type dishwasher of Embodiment 1 configured as described above will be described with reference to FIGS. First, the operation of pulling out the washing tank 2 from the storage port 3a and the ascending / descending operation of the tableware basket 6 from the opening 2a of the washing tank 2 will be described. When the cleaning tank 2 is housed in the outer body 3 (FIG. 5A), the operation tank 18 is pulled out from the housing port 3a of the outer body 3 so that the cleaning tank 2 is slid onto the slide rail 40 and the sliding portion 41. And the other end portion 14a of the second link mechanism 14 slides on the first horizontal groove portion 5a of the guide rail 5 and starts to move toward the storage port 3a. Then, by this operation in the operation unit 18, the front detection sensor 26 detects that the user tries to pull out the cleaning tank 2. The electromagnetic valve 9 controls the driving means 7 to generate an upward force (FIG. 5B).

  At this time, as shown in FIG. 7B, since the front end 122a is held by the receiving portion 11, an upward force A is transmitted, and a downward force B is generated at the other end 14a. From FIG. 5 (a) to FIG. 5 (b), since the other end portion 14a is in the first flat groove portion 5a, a downward force acting on the other end portion 14a generates no force in the moving direction. Only the frictional force C against the horizontal groove 5a is generated. And since the distance of the 1st flat groove part 5a is ensured long enough, the part of the opening part 2a of the washing tank 2 is completely pulled out outside from the storage port 3a. After this, the tableware basket 6 starts to move up and down. Thereby, the utilization of the tableware basket 6 becomes possible 100%.

  Next, when the other end portion 14a reaches the inclined groove portion 5b (FIG. 6A), as shown in FIG. 7A, the other end portion 14a is directed downward by the upward force A acting on the front end portion 122a. The force B works to generate a pull-out direction force D (assist force) to assist the user in the pull-out operation. The front end portion 122a slides in the groove portion 11a of the receiving portion 11, and the front end portion 121a slides in the groove portion 10a of the guide portion 10, and starts moving in the direction opposite to the moving direction of the cleaning tank 2, respectively. . Further, the shape of the boundary portion at the boundary from the first flat groove portion 5a to the inclined groove portion 5b is the second link mechanism 14 accompanying the rotation of the first link mechanism 120 when the tableware basket 6 exists at the rising start position. Needless to say, it is formed in a shape along the rotational locus of the other end portion 14a. Thereby, it becomes possible to move easily from the 1st flat groove part 5a to the slope groove part 5b at the time of the raising start of the tableware basket 6. FIG.

  When the washing tank 2 is further pulled out, the tableware basket 6 is further raised, and the washing tank 2 is completely drawn out (FIG. 6B). The front end portion 122 a stops at the rear end of the groove portion 11 a of the receiving portion 11, and the front end portion 121 a stops at the rear end of the groove portion 10 a of the guide portion 10. At this time, as in the case of the first flat groove portion 5a shown in FIG. 7B, the other end portion 14a reaches the second flat groove portion 5c, and the force in the front-rear direction is reduced by the downward force B acting on the other end portion 14a. Only the frictional force C against the second flat groove portion 5c is generated without being generated. When the user stops the operation of pulling out the cleaning tank 2 here, this is detected by the pre-detection sensor 26 or detected by other detection means (not shown) that the state is completely pulled out. In this way, the electromagnetic valve 9 controls to stop water supply / drainage to the drive means 7. Here, since the tap water is held in the driving means 7 even when the water supply / drainage is stopped, the driving means 7 receives the load of the tableware basket 6 and the tableware basket 6 holds the raised position. Therefore, a safe drawer-type dishwasher can be provided.

  On the other hand, the storing operation of the cleaning tank 2 from the storing port 3a and the descending operation of the tableware basket 6 from the opening 2a to the cleaning tank 2 are in reverse order to the above procedure. From FIG. 6B in which the washing tub 2 is completely pulled out and the tableware basket 6 is completely raised, the user pushes the operation unit 18 in the storing direction, and the start of the storing operation is detected by the rear detection sensor 27. In this case, in order to drain the tap water in the driving means 7 used to generate the upward force and move downward, supply of tap water into the driving means 7 is started. As a result, a downward force that includes the weight of the tableware basket 6 is generated. Then, a counterclockwise rotational torque is generated around the rear end 122b. The front end portion 122a slides in the groove portion 11a of the receiving portion 11, and the front end portion 121a slides in the groove portion 10a of the guide portion 10, and starts moving in the direction opposite to the moving direction of the cleaning tank 2, respectively. .

  In the state where the cleaning tank 2 is pulled out, the other end portion 14a is present at the boundary between the inclined groove portion 5b of the guide rail 5 and the second flat groove portion 5c as shown in FIG. 6B. Here, since this boundary part shape is formed so that it may become a shape along the rotation locus of the other end part 14a accompanying rotation of the 2nd link mechanism 14 when tableware basket 6 exists in the uppermost part, Due to the counterclockwise torque generated immediately after the start of storage, it can be easily moved to the inclined groove portion 5b. When the other end portion 14c reaches the inclined groove portion 5b, as shown in FIG. 7C, the other end portion 14a moves to the inclined groove portion 5b, and the other end is caused by the downward force E acting on the front end portion 122a. An upward force F acts on the portion 14a to generate a storage direction force G (assist force) to assist the user in the storage operation. Therefore, since the driving means 7 assists in the storing direction after the storing operation is started, the storing operability is improved.

  Further, when the cleaning tank 2 is stored, the other end portion 14a is positioned in the first flat groove portion 5a (FIG. 5B), so that the assist force in the storing direction disappears in the same manner as in the above-described withdrawal, The tableware basket 6 is completely lowered. At this time, the drive means 7 reaches the lowermost part, and the solenoid valve 9 controls the drive means 7 by the lowermost detection sensor (not shown) to stop the downward movement. A known sensor such as a non-contact type electromagnetic switch can be used as the lowermost detection sensor. Furthermore, it will be in the accommodation state by accommodating the washing tank 2 (FIG. 5A). At this time, as shown in FIG. 7B, the other end portion 14a reaches the first flat groove portion 5a, and no upward force is generated by the upward force H acting on the other end portion 14a, so that the first flat groove portion 5a is not generated. Only the frictional force I against Thus, since the length of the 2nd flat groove part 5c is ensured also at the time of storage operation, before the tableware basket 6 interferes with the outer body 3, the tableware basket 6 descend | falls to the lowest part, The basket 6 can be used 100%.

  Details of the operation of the operation unit 18 will be described below. FIG. 8A is a diagram showing a drawer movement state, FIG. 8B is a diagram showing a no-operation state, and FIG. 8C is a diagram showing a storage movement state. When the user pulls out the cleaning tank 2 with the operation unit 18, the operation rod 24 is also pulled together with the operation unit 18. At this time, the upper compression spring 25 installed between the operation rod 24 and the operation movable member 22 is compressed, and the washing tank 2 is pulled out through the decorative plate 20 and the front member 21 by the reaction force.

  At this time, the pull-out operation state is detected by the front detection sensor 26 (FIG. 8A), and the electromagnetic valve 9 controls the driving means 7 to generate an upward force. In the case of being in the first flat groove portion 5a, no assist force in the pulling direction is generated, but when reaching the inclined groove portion 5b, a pulling assist force depending on the load is generated. However, when the washing tank 2 is accelerated by the assist force at a speed faster than the user pulls out, the decorative plate 20 and the front member 21 are positioned in front of the operation unit 18 gripped by the user. Thus, the rear portion 24a and the operation movable member 22 are separated from each other (FIG. 8B), and the front detection sensor 26 is turned off.

  At this time, the electromagnetic valve 9 is closed and the driving means 7 is stopped, the upward assist force is not generated, the assist force in the front-rear direction disappears, and the cleaning tank 2 is decelerated. At this time, if the user stops pulling the operation unit 18, the front detection sensor 26 is turned off and the cleaning tank 2 is stopped on the spot. When the user continues to pull the cleaning tank 2, the state returns to the state of FIG. 8A again, and the electromagnetic valve 9 controls the driving means 7 to generate an upward force. As a result, the assist force in the pull-out direction is generated again. Such operation is repeated when the other end portion 14a exists in the inclined groove portion 5b and the tableware basket 6 is raised.

  That is, since the electromagnetic valve 9 controls the driving means 7 while balancing with the user's drawing speed, it is possible to realize a drawing operability independent of the load. During storage, the driving means 7 is controlled by the information of the rear detection sensor 27 in the same way as when the drawer is pulled out, and the lowering operation of the tableware basket 6 can be realized while balancing with the operation speed of the user. That is, since the user's operation speed is balanced while going back and forth between the states of FIG. 8C and FIG. 8B, operability independent of the load can be realized. When the other end portion 14a reaches the first flat groove portion 5a, the assist force in the front-rear direction is not generated, so it goes without saying that the operation stops on the spot if the user stops the operation. As described above, the self-locking mechanism of the washing tub 2 is realized at the time of the drawer and storage operation, and the washing tub 2 does not operate arbitrarily, thus providing a safe dishwasher.

  Next, the action of a clutch (not shown) existing between the rear end portion 122b and one end of the second link mechanism 14 will be described with reference to FIG. In the unlikely event that the drive means 7 or the electromagnetic valve 9 or the like breaks down and the assist force during the operation of pulling out and storing the washing tank 2 does not work, a link control means for controlling the clutch of the rear end 122b is provided. The link relationship is released (cut) by this link control means. As a result, as shown in FIG. 9, the link relationship (rotational constraint) between the first link mechanism 120 and the second link mechanism 14 is cut, and the table basket 6 is moved up and down, and the washing tank 2 is pulled out and stored. And the dish basket 6 does not rise even when the washing tank 2 is pulled out. Further, when the failure of the driving means 7 or the like is eliminated, the link relation is connected again by the link control means so that the operation can be performed as described above.

  However, if the tableware basket 6 stops at the raised position, the water present in the drive means 7 is instructed to the electromagnetic valve 9 (not shown) and drained, and the tableware basket 6 is moved to the bottom. And move. Alternatively, a drain cock may be installed in the hydraulic cylinder that is the driving means 7 to drain the tap water in the hydraulic cylinder. By performing such a recovery operation, the washing tank 2 can be pulled out and stored with the tableware basket 6 positioned at the lowermost position, and the minimum function as a dishwasher can be secured. And it can prevent that it cannot be used at all until repair of a raising / lowering mechanism part is completed.

  Further, here, the opening operation of the electromagnetic valve 9 for controlling the driving means 7 is performed only by the ON signal of either of the detection sensors 26 and 27. However, when the sensor is added and the other end portion 14a exists in the inclined groove portion. It goes without saying that the driving means 7 can be controlled so as not to operate when it exists in each of the flat groove portions 5a and 5c. In this case, the frictional force generated in each of the flat groove portions 5a and 5c is not generated, and the drawing and storing operation in each of the flat groove portions 5a and 5c is further facilitated. Although a method using a dead zone structure using the compression springs 23 and 25 is shown here, a pressure sensor may be used. In this case, it is possible to configure a dead zone by turning on when a certain load or more is applied.

  According to the mobile storage device of the first embodiment configured as described above, the raising and lowering operation of the tableware basket as the storage body is realized only by the drawer and storage operation of the cleaning tank as the mobile body, which is a conventional operation. As a result, no extra operation is required to raise and lower the tableware basket, and erroneous operations are unlikely to occur. Furthermore, since the raising / lowering of the tableware basket is performed in a range in which the storage body is sufficiently pulled out from the moving body, a space where the tableware basket can be used can be sufficiently secured. From the above, it is possible to maintain the same operability as in the case where there is no elevating mechanism and the storage property, it is possible to arrange even if there is a sink or the like in the upper part in the moving direction, and in the loading and unloading of stored items There is no need for the user to bend and the mobile storage device with improved operability can be provided.

  Further, the first link mechanism can be formed with an easy configuration called an X member, and the shape of the guide rail can be raised and lowered only by forming the shape of the guide rail with an easy shape such as a flat groove portion and an inclined groove portion. It becomes possible to carry out.

  Furthermore, in the unlikely event that the mobile storage device breaks down, the mobile body can be operated as before by setting the first link mechanism and the second link mechanism to the open (free) state. Although the operability for taking out the stored item such as the user bending over is deteriorated, the original stored item in the movable body can be stored and taken out. Furthermore, at the start of movement of the storage body when the mobile body is stored and pulled out, the other end portion can smoothly operate the boundary between each flat groove portion and the inclined groove portion by the rotational torque due to the operating force. The moving operation of the storage body can be realized without making the user aware of the part, and the operability can be maintained.

  Furthermore, by controlling the assist force according to the user's operation status (operation direction and speed), the operation force required when moving the storage body is assisted, and the operation force of the washing tank when moving the storage body is stored. Therefore, the operability and safety are improved because the assist is performed regardless of the capacity of the device and the self-locking is performed at all positions. As a result, even when a heavy object is stored, this moving mechanism can be applied, and the drawer storage operability that does not depend on the capacity of the stored object can be secured, so that the same operability can be realized at any time and the movement is easy to use. It becomes a mechanism.

  In addition, although the example provided with a drive means was shown in the said Embodiment 1, it is not restricted to this, In the case of a mobile storage apparatus with a small storage capacity etc., even if there is no assist force by a drive means, the said embodiment It goes without saying that the storage body can be moved in the outer and inner directions by performing an operation of pulling out and storing in the same manner as in FIG. Further, when the operation of pulling out and storing itself is performed using a driving source, the assisting force in the outward and inward directions by the driving means is not required.

  Further, it is possible to mount a weight sensor on the upper surface of the driving means and use the weight information of the tableware basket through the tableware basket receiving portion. With this information, it is possible to control a plurality of driving means and make it difficult to depend on the load. Moreover, although the example which utilizes the hydraulic cylinder which utilizes tap water pressure as a drive means is shown, it cannot be overemphasized that the drive means using an air pressure, a hydraulic pressure, or an electric motor can also be used. However, in the case of a dishwasher, since tap water is an essential element, an additional drive source is unnecessary, and use of tap water is preferable from the viewpoint of hygiene. Further, since the driving means is installed inside the cleaning tank, even if some water leakage occurs in the driving means, the leaked tap water flows into the cleaning tank, so that double water leakage can be prevented.

Embodiment 2. FIG.
10 is a cross-sectional view showing a state in which the cleaning tank of the mobile storage device according to Embodiment 2 of the present invention is pulled out, FIG. 11 is a top view of the mobile storage device shown in FIG. 10, and FIG. FIG. 13 is a partially enlarged view showing details of a region surrounded by a one-dot chain line in FIG. 11. In the figure, the same parts as those in the first embodiment are denoted by the same reference numerals and the description thereof is omitted. In the first embodiment, an example in which the first link mechanism is configured by the X member has been described. However, in the second embodiment, the case where the first link mechanism is formed by one bar member will be described. To do. Therefore, since the basic operation is the same as that of the first embodiment, the same parts are omitted as appropriate.

  In the second embodiment, there is no portion corresponding to the receiving portion 11 of the first embodiment. For this reason, the tableware basket 6 is directly supported by the drive means 7 via the tableware basket receiving part 6a. Thus, the tableware basket receiving portion 6a has a structure in which the relative position is substantially restrained by the driving means 7 in the horizontal plane and the vertical direction. A known structure such as a pin and pin hole structure can be used for restraining the horizontal plane, and a one push lock mechanism can be used for restraining in the vertical direction.

  The tableware basket 6 is provided with two front rollers 32 and two rear rollers 33 in the front-rear direction of the tableware basket 6 so as to restrain the tableware basket 6 so as to be movable only in the vertical direction with respect to the washing tub 2. By this installation, the rotation of the tableware basket 6 around the horizontal axis in the width direction is restricted. The first link mechanism 124 is formed by a position restraining roller whose front end portion 124 a is rotatably formed on the tableware basket 6, and is rotated with respect to the tableware basket 6 and the moving direction of the washing tub 2. It is installed so that it can move horizontally. The rear end portion 124b is connected to one end of the second link mechanism 14 via a clutch.

  The front end portion 124a is detachably attached to the tableware basket 6 using a known technique such as a link mechanism used for fixing the clothes drying basket to the clothes drying basket. Therefore, it is possible to obtain a structure having a degree of freedom in the moving direction and the horizontal direction in which the distance between the front end portion 124a and the rear end portion 124b is variable. For this reason, while the structure of the tableware basket 6 is simplified, the freedom degree of design of a link member etc. increases.

  According to the mobile storage device of the second embodiment configured as described above, the same effects as those of the first embodiment can be obtained, and the number of components can be reduced. Compared with the first mode, it can be removed more easily. Therefore, the cleaning tank can be easily cleaned.

Embodiment 3 FIG.
14 is a cross-sectional view showing a state in which the mobile storage device is pulled out according to Embodiment 3 of the present invention, and FIG. 15 is a cross-sectional view showing a storage state of the mobile storage device shown in FIG. As shown in the figure, here, an elevating dishwasher as an example of a mobile storage device installed in the upper part of a system kitchen or the like is shown. The basic structure is the same as that of the second embodiment. However, since it is formed on the upper side, an operation portion 18 for pulling out or storing the user is disposed at the lower portion of the cleaning tank 2. The tableware basket 6 is restrained by a plurality of front rollers 32 and rear rollers 33 so as to be movable only in the front-rear direction.

  In the third embodiment, the first link mechanism 125 made of a rod member is used as the first link mechanism as in the case of the second embodiment. The first link mechanism 125 is formed of a stick member that expands and contracts. For this reason, if the connection between the tableware basket 6 and the first link mechanism 125 has a degree of freedom of rotation only, it becomes possible to have a degree of freedom only in the outer and inner directions of the tableware basket 6. Moreover, the raising / lowering operation | movement as a movement from the storage port 3a of the outer body 3 of the washing tank 2 has a structure implement | achieved by the raising / lowering drive means which is not shown in figure. Furthermore, since the movement of the tableware basket 6 is horizontal and the driving means required for the movement can be performed with a force smaller than that of the raising / lowering, it is not necessary to newly install a driving means for assisting the movement of the tableware basket 6. Yes, it is possible to use the driving force of the raising / lowering driving means for raising and lowering the cleaning tank 2.

  Next, the operation of the mobile storage device of the third embodiment configured as described above will be described. First, as shown in FIG. 15, when the cleaning tank 2 is stored, the user starts to draw out (lower) the cleaning tank 2 via the operation unit 18. Then, the raising / lowering drive means (illustration omitted) of the washing tank 2 operates, and the downward movement operation of the washing tank 2 is started. Next, with the lowering operation of the cleaning tank 2, the other end portion 14a of the second link mechanism 14 moves through the first parallel groove portion 5a of the guide rail 5 and moves to the inclined groove portion 5b. The first link mechanism 125 moves forward by the connection of one end of the second link mechanism 14 at the inclined groove 5b, and the tableware basket 6 starts moving forward. And finally, as shown in FIG. 14, the washing tank 2 will be in the state pulled out completely, and the tableware basket 6 will also be in the state which moved completely ahead with the operation | movement.

  According to the mobile storage device of the third embodiment configured as described above, the tableware basket is provided with the lifting drive means used for the lifting and lowering operation of the washing tank as well as the same effect as the first embodiment. Can be used instead of the driving means 7 in the case of the first embodiment.

  In the above embodiments, the shape of the guide rail is shown from the first flat groove portion to the inclined groove portion. However, the impact on the storage object installed in the storage body is softened, and the acceleration at which the storage body moves is substantially reduced. It goes without saying that other shapes may be used as long as they are continuous. In each of the above embodiments, the drawer-type and elevating-type dishwashers have been shown. However, the present invention is not limited to this and can be applied to other storage shelves and the like. be able to.
