  In the above structure, it is necessary to connect the movable lid and the link so as to be rotatable. For this reason, in conventional dishwashers, stepped screws (or stepped bolts) are used to connect the movable lid and the link. However, in a structure using a stepped screw, there is a possibility that the tightening may not be performed correctly, and in that case, it is also assumed that water leaks from the cleaning tank. In addition, since maintenance work on existing products is performed in a limited space of a kitchen, it may be difficult to turn the stepped screw with a tool, or the stepped screw may be lost.

  In view of the above situation, the present specification provides a new connection structure between the movable lid and the link.

  In order to achieve the above object, in the technique disclosed herein, the link and the movable lid are connected by engaging a protrusion provided on one of the link and the movable lid with a hole or slit provided on the other. To do. According to such a configuration, it is not necessary to use a stepped screw for the connecting portion between the link and the movable lid, and the above-described problem can be solved.

In accordance with one aspect of the technology described above, a new and useful dishwasher is disclosed. This dishwasher is slidable with respect to the housing, the housing having an opening in the upper portion, and attached to the housing via a link. And a movable lid that opens and closes the opening. And in the connection part of a link and a movable lid, the projection part provided in one of a link and a movable lid is engaging with the hole or slit provided in the other of a link and a movable lid. In the embodiment in which the protrusion is engaged with the slit, it is preferable that a head larger than the width of the slit is formed at the tip of the protrusion.

The figure which shows the external appearance of the dishwasher of an Example. The exploded view which shows the structure of the dishwasher of an Example (some components are abbreviate | omitting illustration). The figure which shows a movable lid and a link. The figure which shows a link alone.

  In one embodiment of the dishwasher according to the present technology, it is preferable that a protrusion provided on one of the link and the movable lid is engaged with a slit provided on the other of the link and the movable lid. With the structure in which the protrusion is engaged with the slit, the movable lid can be easily attached to and detached from the link and the manufacture and maintenance of the dishwasher is easier than in the structure in which the protrusion is engaged with the hole.

  In the above-described embodiment, it is preferable that a head larger than the width dimension of the slit is formed at the tip of the protrusion. According to such a structure, it is prevented that the projection part engaged with a slit removes from the slit unintentionally.

  In the above-described embodiment, it is preferable to further include a biasing member. In this case, it is preferable that the urging member urges at least one of the link and the movable lid in a direction in which the engagement between the protrusion and the slit is maintained. For example, when a slit is formed in the movable lid, and the slit is a slit opened in front of the slit, the biasing member biases the movable lid forward or biases the link rearward. There should be. On the other hand, if the structure of the slit is reversed, the urging direction by the urging member may be reversed.

  In one embodiment of the dishwasher according to the present technology, it is preferable that the upper portion of the housing is openable so that the movable lid can be attached to and detached from the link. According to such a structure, for example, during maintenance, the operator can remove or attach the movable lid from the dishwasher without disassembling the casing.

  The dishwasher 10 of an Example is demonstrated referring drawings. As shown in FIG. 1, the dishwasher 10 includes a housing 12 and a cleaning tank 14 that can be accommodated in the housing 12. The casing 12 has an open front portion 12a and supports the cleaning tank 14 so as to be slidable in the front-rear direction. The cleaning tank 14 is pulled out of the housing 12 by sliding forward, and is accommodated in the housing 12 by sliding backward. The washing tank 14 has an opening 14a in the upper part, and accommodates the used tableware 2 in the opening 14a. Inside the washing tank 14 are provided a table basket 16 that supports the tableware 2 and a washing nozzle 18 that rotates while spraying the washing liquid.

  As shown in FIGS. 1 and 2, the housing 12 includes a top surface 12e, a right wall 12c, a left wall 12d, and a back wall 12b. Forming the body. A pair of rail mechanisms 19 are attached to the housing 12. The pair of rail mechanisms 19 supports the cleaning tank 14 so as to be slidable. In addition, the structure of the housing 12 in a present Example is an example, and the structure of the housing 12 is not limited to a specific thing.

  As shown in FIG. 2, the dishwasher 10 includes a movable lid 20. The movable lid 20 is disposed inside the housing 12, and closes the opening 14 a of the cleaning tank 14 when the cleaning tank 14 is accommodated in the housing 12. The movable lid 20 is attached to the housing 12 via a plurality of links 30. Although it is an example, in this embodiment, two links 30 are arranged on each of the right edge 20c and the left edge 20d of the movable lid 20. Each link 30 is attached to the housing 12 by a screw 40. The screw 40 is a stepped screw. Thereby, the link 30 is rotatably supported with respect to the housing 12. The link 30 is also connected to the movable lid 20 so as to be rotatable. The connection structure between the movable lid 20 and the link 30 will be described in detail later.

  The structures of the movable lid 20 and the link 30 will be described in detail with reference to FIGS. As shown in FIG. 3, the movable lid 20 includes a generally plate-shaped lid body 22 and a frame body 24 fixed around the lid body 22. The lid body 22 is formed of a resin material. The frame body 24 is formed of a metal material. The movable lid 20 is biased forward by a tension spring 42. Note that one end of the tension spring 42 (not shown) is fixed to the housing 12. Here, the tension spring 42 may be a spring having another structure or another elastic member. Further, the tension spring 42 (or an urging member instead thereof) may urge the link 30 in the one direction described above.

  As shown in FIG. 4, the link 30 includes a plate-like link main body 32. The link body 32 is provided with a hole 34 for the screw 40. That is, the center of rotation of the link 30 is the position of the hole 34. The link main body 32 is provided with a contact protrusion 36. The abutting protrusion 36 is a cylindrical protrusion. The contact protrusion 36 contacts the inclined surface 14 b (see FIG. 2) of the cleaning tank 14 when the cleaning tank 14 is accommodated in the housing 12. The inclined surface 14b is an inclined surface whose normal direction faces rearward and downward, and rotates the contacted link 30 in one direction (direction in which the upper portion of the link 30 moves rearward). When the link 30 rotates in one direction, the movable lid 20 translates backward and downward to close the opening 14a of the cleaning tank 14.

  On the other hand, when the cleaning tank 14 is pulled out from the housing 12, the inclined surface 14 b of the cleaning tank 14 is separated from the contact protrusion 36 of the link 30. As a result, the link 30 rotates in the other direction (the direction in which the upper part of the link 30 moves forward) by the biasing force of the tension spring 42. When the link 30 rotates in the other direction, the movable lid 20 moves forward and upward to open the opening 14a of the cleaning tank 14. Thus, the link 30 swings with the sliding movement of the cleaning tank 14, and opens and closes the opening 14 a of the cleaning tank 14 by the movable lid 20.

  Next, a connection structure between the movable lid 20 and the link 30 will be described. As shown in FIG. 3, the frame body 24 of the movable lid 20 is integrally provided with a link connecting portion 26 that is connected to the link 30. The link connecting portions 26 are provided at two positions on the front and rear sides of the right edge 20c and the left edge 20d of the movable lid 20, respectively. Since the movable lid 20 has a symmetrical structure, only the right edge 20c of the movable lid 20 is shown in FIG. The link connecting portion 26 is provided with a slit 28. The slit 28 extends in the front-rear direction, and its front is opened. The opening portion 28a of the slit 28 has a tapered shape whose width gradually increases.

  On the other hand, as shown in FIGS. 3 and 4, the link 30 is provided with a connecting projection 38. The connecting projection 38 is provided integrally with the link body 32. The connecting projection 38 extends perpendicular to the plate-like link body 32. The connection protrusion 38 engages with the slit 28 of the movable lid 20, whereby the movable lid 20 and the link 30 are rotatably connected. A head 38 a larger than the width dimension of the slit 28 is formed at the tip of the connecting projection 38. The head 38 a is formed only on a part of the connecting projection 38 in the circumferential direction. Specifically, the head portion 38a is formed in the upper half-circular portion, but the head portion 38a is not formed in the lower half-circular portion. In addition, a reinforcing rib 38b is formed integrally with the connecting protrusion 38a. The reinforcing rib 38b extends in a plate shape in the radial direction with respect to the connecting protrusion 38.

  As described above, in the dishwasher 10 according to the present embodiment, the connection protrusion 38 provided on the link 30 is engaged with the slit 28 provided on the movable lid 20. With such a structure, it is not necessary to use a stepped screw or other screws at the connecting portion between the link 30 and the movable lid 20. Therefore, the movable lid 20 can be easily attached to and detached from the link 30, and the dishwasher 10 can be easily manufactured and maintained.

  Regarding the structure described above, the positional relationship between the slit 28 and the connecting projection 38 may be interchanged. That is, the slit 28 may be provided in the link 30 and the connecting projection 38 may be provided in the movable lid 20. The slit 28 may be a hole that can be engaged with the connecting projection 38. Even if the connecting projection 38 is structured to engage with the hole, it is not necessary to use a stepped screw or other screws, and the manufacture and maintenance of the dishwasher 10 can be facilitated.

  In the dishwasher 10 of this embodiment, a head 38 a larger than the width dimension of the slit 28 is formed at the tip of the connecting projection 38. According to such a configuration, the protruding portion 38 that engages with the slit 28 is prevented from being unintentionally detached from the slit 28. Since the movable lid 20 and the link 30 are firmly connected, the movable lid 20 can be strongly pressed against the opening 14a of the cleaning tank 14, and water leakage from the cleaning tank 14 can be reliably prevented. it can. However, it is an additional matter to provide the head portion 38a in the connecting projection portion 38, and it is not always necessary.

  Moreover, in the dishwasher 10 of a present Example, the tension spring 42 has the structure which urges | biases the movable cover 20 ahead so that engagement with the slit 28 and the connection projection part 38 may be maintained. According to such a configuration, the protruding portion 38 that engages with the slit 28 is prevented from being unintentionally detached from the slit 28. The tension spring 42 may bias the link 30 instead of the movable lid 20. In this case, the tension spring 42 may be configured to urge the link 30 rearward. The tension spring 42 is an example of an urging member, and may be another elastic body.

  As shown in FIG. 2, in the dishwasher 10 according to the present embodiment, when the top surface 12 a is removed from the housing 12, the upper portion of the housing 12 is opened so that the movable lid 20 can be attached to and detached from the link 30. It is configured to be. With such a structure, for example, during maintenance, an operator can remove or attach the movable lid 20 from the dishwasher 10 without disassembling the housing 12. Therefore, it is easy to work in a kitchen with limited space.

  As mentioned above, although the Example of this invention was described in detail, these are only illustrations and do not limit a claim. The technology described in the claims includes various modifications and changes of the specific examples illustrated above.

  Although omitted in the above description, the dishwasher 10 of the present embodiment, like the conventional dishwasher, has a circulation pump for cleaning liquid, a heater, a blower fan, an electromagnetic valve, various sensors, and their operations. It has a computer to control.

  The technical elements described in this specification or the drawings exhibit technical usefulness alone or in various combinations, and are not limited to the combinations described in the claims at the time of filing.
