BACKGROUND OF THE INVENTION
The present invention includes a cleaning machine body and a cleaning tank that can be stored in a storage space of the cleaning machine body , and the cleaning tank is horizontal or substantially horizontal from a storage position and a storage space in which the cleaning tank is stored. The present invention relates to a dishwasher configured to be movable and retractable with respect to the main body of the washing machine between a drawer position drawn in a direction.
[0002]
[Prior art]
Such dishwashers, to wash Kiyoshiki body, washing Kiyoshiso is between the extraction position drawn from the washing machine body and accommodating position to be housed in the washing machine body, accommodating the movement and the drawer moves The actual situation is that no special consideration has been given to the storage movement and withdrawal movement of the washing tank.
[0003]
[Problems to be solved by the invention]
In other words, the washing tank of a dishwasher has a considerable difference in weight between when a large number of dishes are stored in the washing tank and when they are empty. When the drawer is moved, it is lightweight because the washing tank is empty, and the washing tank is moved to the storage position and the drawer position vigorously, generating a loud impact sound, and impacting the washing machine body and the washing tank There's a problem.
[0004]
In particular, when storing and moving the cleaning tank, the cleaning tank is pushed forward and moved, so it is easier to apply a stronger force than when pulling out, and fingers can be packed between the cleaning machine body and the cleaning tank. There is also a problem, especially in the case of storage movement, and in the case of a drawer type dishwasher, since a heavy washing pump etc. is attached to the washing tank side, if it is stored and moved with a strong force There was room for improvement in this regard because of the large inertial force.
[0005]
The present invention has focused on these conventional problems, and an object, even if is housed moved with a strong force the housing freely cleaning tank against washer body, washing machine body and the cleaning tank, etc. It is an object of the present invention to provide a dishwasher that does not have a risk of giving a large impact to the kitchen and that does not have a risk of clogging fingers.
[0006]
[Means for Solving the Problems]
In order to achieve this object, according to the first aspect of the present invention, a cleaning machine main body and a cleaning tank that can be stored in a storage space of the cleaning machine main body are provided, and the cleaning tank is provided in the storage space. A dishwasher configured to be movable and retractable with respect to the main body of the washing machine between a storage position stored in the storage space and a pull-out position pulled out horizontally or substantially horizontally from the storage space, When the cleaning tank is stored and moved to the storage position side, a one-way system that decelerates the moving speed of the cleaning tank in the storage movement direction between the storage position and the deceleration operation position before reaching the storage position. The damper-type storage buffer means is provided between the cleaning tank and the main body of the cleaning machine, and when the cleaning tank is stored and moved, the storage biasing operation position located at or near the deceleration operation position is When the cleaning tank is urged and moved to the storage position side between the storage positions and the cleaning tank is pulled and moved to the drawer position side, the drawer urging action position is closer to the drawer position side than that. A toggle mechanism that urges and moves the cleaning tank to the pull-out position between the positions, and after the cleaning tank is stored and moved from the pull-out position to the storage position, The cleaning tank is linked with the cleaning tank, and when the cleaning tank moves to the pulling position side from the pulling biasing action position, the cleaning tank is between the pulling position and the storage biasing action position. It is configured to leave.
[0007]
That is, when the cleaning tank that can be stored in the storage space of the cleaning machine body is stored and moved to the storage position side, the moving speed of the cleaning tank in the storage movement direction is reduced at the deceleration operation position before reaching the storage position. damper type storage buffer means for deceleration, because provided between the cleaning tank and the cleaning machine body, also be accommodated move cleaning tank even with a strong force, the cleaning tank reaches the deceleration acting position, The movement speed of the washing tub is reduced by the action of the damper-type storage buffering means, so that a large impact is not given to the main body of the washing machine or the washing tub , no loud noise is generated, and the position of the deceleration action position is Depending on the setting, it is possible to surely prevent finger jamming between the cleaning machine main body and the cleaning tank .
[0008]
In particular, the wrong presence of dishes in the washing Kiyoshiso, likely to housing moves the cleaning tank and is despite a strong force air, further, even if the cleaning tank is empty, such as cleaning pump attached to gravimetrically heavy, for thereby acting great inertia force, operational effect of that is also remarkable.
[0010]
In addition, when the cleaning tank to be stored and moved reaches the storage urging operation position located at or near the deceleration operation position, it is urged and moved to the storage position side by the toggle mechanism , and the damper type storage buffer The washing tank that receives the deceleration action by the means also receives the biasing movement action by the toggle mechanism , and the washing tank is moved to the storage position at an appropriate speed by the cooperation of both actions.
[0012]
Further, the cleaning tank is urged and moved to the drawer position side by the toggle mechanism when it reaches the drawer biasing action position not only during the storage movement to the storage position side but also during the drawer movement to the drawer position side. Therefore, the operation of pulling out the cleaning tank can be performed lightly and easily.
[0013]
According to the invention described in claim 2 , the toggle switching position of the toggle mechanism is such that the storage urging action position is located closer to the drawing movement direction of the cleaning tank than the drawer urging action position. The cleaning tank is configured to be changed by a drawing movement toward the drawing position.
[0014]
Therefore, when the cleaning tank is moved and moved, the finger can be prevented from clogging between the washing machine body and the cleaning tank . This makes it possible to provide a dishwasher that is extremely rational for actual use.
[0015]
DETAILED DESCRIPTION OF THE INVENTION
An embodiment of a dishwasher according to the present invention will be described with reference to the drawings.

A cleaning pump 3 and the like are disposed below the bottom of the cleaning tank 2, and a cleaning nozzle 4 and a heater 5 and the like are disposed inside the cleaning tank 2. In the interior of 2, a cleaning basket 6 for storing and placing tableware and the like is removably stored.
[0016]
In a front view of the dishwasher, a pair of slide mechanisms 7 constituted by rails or the like are provided inside the left and right sides of the washing machine main body 1, and the washing tub 2 is disposed via the pair of left and right slide mechanisms 7. The cleaning machine body 1 is configured to be capable of sliding in the storage movement direction indicated by arrow A and sliding in the pull-out movement direction indicated by arrow B along the horizontal or substantially horizontal direction. .
A main body lid 9 having a handle 8 and the like is attached to the front surface of the cleaning tank 2 and is slid in the storage movement direction A, whereby the cleaning tank 2 is stored in the cleaning machine main body 1 as shown in FIG. As shown in FIG. 1, the washing tub 2 is moved to the washing machine main body 1 so that the tableware can be washed and dried in the state of being accommodated in the space and is slid in the drawer movement direction B. The lid 10 is configured so that the tableware and the cleaning basket 6 can be taken out and stored in a state where the storage tank 6 is pulled out from the storage space, and the cleaning tank 2 is stored in the state where the upper opening of the cleaning tank 2 is sealed. It is attached to the inside upper part of the washing machine main body 1.
[0017]
In a front view of the dishwasher, on one side of the left and right inner sides of the washing machine main body 1, as shown in FIGS. 3 and 4, there are racks 11 along the storage movement direction A and the drawer movement direction B of the washing tank 2. A rotary damper 12 as a damper-type storage buffer means is attached to the washing tank 2 side, and a pinion 13 protruding downward from the rotary damper 12 is joined to and detached from the rack 11 on the washing machine body 1 side. It is configured to be possible.
Although a detailed description of the rotary damper 12 is omitted, a rotating body (not shown) that is filled with oil or the like and that rotates in conjunction with the pinion 13 is provided. The rotary damper 12 in this embodiment has a function of braking the rotation of the pinion 13 by applying a resistance to the rotating body by a fluid. When the rotary damper 12 in this embodiment moves the cleaning tank 2 in the storage movement direction A, Only a one-way type which is configured to apply braking to the rotation of the pinion 13 is used.
[0018]
Accordingly, the cleaning tank 2 at the pulling position D pulled out from the storage space of the cleaning machine main body 1 is moved along the storage movement direction A and moved to the storage position C side stored in the storage space of the cleaning machine main body 1. At this time, when the pinion 13 of the rotary damper 12 is engaged with the rack 11, that is, when the pinion 13 reaches the deceleration operation position E where it is engaged with the rack 11, the rotation of the pinion 13 is braked by the action of the rotary damper 12. Even if the washing tank 2 is moved at a high speed, the washing tank 2 moves slowly in a decelerated state thereafter.
The reduction of the moving speed with respect to the cleaning tank 2 is intended to alleviate the impact and prevent the user from clogging a finger or the like between the cleaning tank 2 and the cleaning machine body 1. E is set to a position necessary for that, for example, about 100 mm before the cleaning tank 2 reaches the storage position C.
[0019]
A catcher pin 14 protrudes laterally at the rear side of the left and right sides of the cleaning tank 2, and the main body of the washer so that the catcher 15 engaged with the catcher pin 14 corresponds to the catcher pin 14. 1 is provided behind the left and right sides on the inside. The catcher 15 is configured by a substantially L-shaped lever, and an intermediate portion of the catcher 15 is pivotally attached to the projecting pin 16 from the washing machine main body 1. A slit-like engagement groove 15a into which the catcher pin 14 enters is formed.
Further, one end of a spring mounting plate 17 is pivotally attached to the pin 16, and a substantially arc-shaped guide groove 17a is formed at the other end of the spring mounting plate 17, and the guide groove 17a. A return pin 19 projecting from the return plate 18 is inserted therein, and a spring 20 is stretched between the lower free end portion of the catcher 15 and the spring mounting plate 17.
[0020]
The return plate 18 is also composed of a substantially L-shaped lever, and the return pin 19 projects from the lower free end thereof, and the upper free end is bent so as to incline outward. In addition, an inclined guide portion 18a is formed, and an intermediate portion of the return plate 18 is rotatably attached around the fixed pin 21 protruding from the cleaning machine main body 1 and the storage tank 2 is moved and moved by the return spring 22. It is biased to rotate in the direction A, that is, in the clockwise direction in FIG.
In this way, as will be described in detail later, the cleaning tank 2 is urged and moved to the storage position C or the drawing position D side by the catcher 15 that engages with the catcher pin 14, the spring mounting plate 17, the spring 20, and the like. configured the belt glue mechanism 23 is a spring mounting plate 17 and the back plate 18 constituting the toggle mechanism 23, during the movement of the housing the movement direction a side of the washing tub 2 and the drawer moving direction B side, The biasing force switching position of the toggle mechanism 23 is changed.
[0021]
Next, the operation of the dishwasher having the above-described configuration will be described with reference to FIGS. 5 and 6 mainly focusing on the operation of the rotary damper 12 and the toggle mechanism 23.
3 to 6, the relative position of the cleaning tank 2 with respect to the cleaning machine body 1 is shown with reference to the rear end of the cleaning tank 2.
[0022]
When the cleaning tank 2 is pushed in the storage movement direction A side in the state where the cleaning tank 2 is at the pulling position D shown in FIG. 1, the catcher pin protruding from the cleaning tank 2 as shown in FIG. 14 enters the engaging groove 15a of the catcher 15 and rotates the catcher 15 clockwise in the figure. Thereafter, as shown in FIG. 3 and FIG. When reaching E, the pinion 13 protruding from the rotary damper 12 is joined to the rack 11.
The pinion 13 rotates with the mating of the pinion 13 with the rack 11, but the rotation of the pinion 13 is braked by the action of the rotary damper 12, so even if the washing tank 2 is pushed in vigorously, the deceleration action position After E, that is, from about 100 mm before the cleaning tank 2 reaches the storage position C, the moving speed of the cleaning tank 2 is decelerated and moves slowly.
[0023]
As shown in FIG. 5B, the spring 20 of the toggle mechanism 23 exceeds the pin 16 at the same time as the cleaning tank 2 reaches the deceleration action position E or before and after the vicinity of the deceleration action position E. Since the spring 20 exceeds the toggle switching position H, the catcher 15 that has been urged to rotate counterclockwise by the spring 20 is urged to rotate clockwise.
In other words, when the cleaning tank 2 reaches the storage biasing operation position F, the cleaning tank 2 is biased and moved toward the storage position C by the action of the toggle mechanism 23. As a result, the cleaning tank 2 is moved to the toggle mechanism. By the urging movement by 23 and the braking by the rotary damper 12, it is moved to the storage position C at a substantially constant speed, and at the storage position C, the upper opening of the cleaning tank 2 is sealed from above by the lid body 10.
[0024]
Further, when the catcher pin 14 moves in the storage movement direction A along with the movement of the cleaning tank 2, the catcher pin 14 is guided by the inclined guide portion 18a of the return plate 18, and (a) in FIG. As shown in FIG. 5 (B), the catcher pin 14 moves while sliding on the side surface of the return plate 18 and the cleaning tank 2 reaches the storage position C. As shown in (c), it is located rearward of the return plate 18.
Therefore, when the cleaning tank 2 is next pulled out in the pulling movement direction B side, first, the catcher pin 14 comes into contact with the rear side of the return plate 18, and as shown in FIG. Is rotated counterclockwise against the urging force of the return spring 22.
[0025]
By rotating the return plate 18 in the counterclockwise direction, the toggle switching position H of the toggle mechanism 23 with respect to the position of the cleaning tank 2 is changed. At the urging action position G, the urging direction by the toggle mechanism 23 is switched, and the cleaning tank 2 is urged and moved toward the drawing position D side. In other words, the storage biasing action position F is positioned on the side of the drawer tank movement direction B with respect to the drawer biasing action position G, and the drawer biasing action position G is set to about 30 mm from the storage position C. ing.
Therefore, even if the cleaning tank 2 is pulled out, if the pulling amount is less than 30 mm, the cleaning tank 2 is returned to the storage position C by the action of the toggle mechanism 23, and if it exceeds 30 mm, the pulling position D is reached. In this case, braking by the rotary damper 12 does not act, and the cleaning tank 2 is pulled out to the drawing position D relatively quickly.
[0026]
[Another embodiment]
(1) In the previous embodiments, in addition to the rotary damper 12 which serves as a storage buffer means of the damper-type, an example in which a toggle mechanism 23, for the damper type storage buffer means its, especially The damper is not limited to the rotary damper 12, and for example, a cylinder type damper or other dampers having various structures can be used. It can also be provided.
