The present invention relates to a dishwasher for washing dishes and the like, and more particularly to a door opening / closing mechanism of a dishwasher.

  Conventional dishwashers of this type are configured as shown in FIGS. 9 to 12 (see, for example, Patent Document 1).

  FIG. 9 is a side sectional view of the conventional dishwasher described in Patent Document 1, FIG. 10 is a side sectional view of the dishwasher when the door is closed, and FIG. 11 is an opening of the dishwasher door. FIG. 12 is an initial side wall cross-sectional view, and FIG. 12 is a side wall cross-sectional view when the door body of the dishwasher is opened.

  9-12, the conventional dishwasher accommodates to-be-washed | cleaned objects 101, such as tableware, in the washing tank 102, and obstruct | occludes the front opening part 103 provided in the washing tank 102 with the upper door body 104 and the lower door body 105. FIG. After that, the cleaning pump 106 is operated and the cleaning water is jetted to perform the cleaning and rinsing steps of the object 101 to be cleaned. The lower door body 105 is configured to be able to rotate and open to a position where the inner surface of the lower door body 105 is upward and substantially horizontal, in front of and below the front opening 103 by the lower door support member 107. 108 can be pulled out.

  On the other hand, the upper door body 104 is configured to open and close in the upper space of the main body 111 by the first upper door support member 109 and the second upper door support member 110.

  Further, the lower door support member 107 and the first upper door support member 109 are connected by the interlocking portion 112, and when the lower door body 105 is opened and closed, the upper door body 104 is also opened and closed in conjunction with each other. Since the front opening 103 can be opened and closed by operation, an easy-to-use dishwasher is realized.

  Further, the connecting portion between the first upper door support member 109 and the interlocking portion 112 has play by the cylindrical connecting shaft 113 provided in the first upper door support member 109 and the long hole portion 114 provided in the interlocking portion 112. After the upper door body 104 reaches the closed state, only the lower door body 105 is operated, and the locking means 115 provided on the lower door body 105 is locked to the side wall of the cleaning tank 102. The upper door body 104 and the lower door body 105 are closed.

  As a result, the door-to-door seal member 116 attached to the upper door 104 can be sealed by the door-to-door seal receiver 117 provided on the lower door 105, and water leakage can be prevented.

  However, in the configuration of the dishwasher described in Patent Document 1, the upper door body 104 is opened upward, so that an open space for the upper door body 104 is required above the dishwasher body, and installation is easy. In addition, there is a problem that the upper door 104 is covered on the upper part of the front opening 103, so that it is troublesome to put in and out the article to be cleaned 101.

  In order to solve such a problem, there is one in which an upper door body and a lower door body are overlapped and opened to the front and lower side of the cleaning tank (for example, see Patent Document 2).

  FIG. 13 is a side sectional view of the conventional dishwasher described in Patent Document 2 when the door is closed, and FIG. 14 is a side sectional view of the dishwasher when the door is opened.

  13 and 14, the dishwasher includes an upper door body 118 and a lower door body 119 that are respectively disposed in front of the front opening 123 of the washing tub 122 by the upper door support member 120 and the lower door support member 121. It is configured to be able to rotate and open to a position where the inner surface is substantially horizontal upward, and the upper door body 118 and the lower door body 119 are opened so as to overlap each other.

  The tableware basket 124 is configured to be pulled out to the inner surface of the upper door body 118. Since this dishwasher does not require an open space for the upper door body 118 above the dishwasher body, it is easier to install than the one in which the upper door body 118 opens upward, and the upper surface of the dishwasher body is a storage space. Easy to use because it can be used as Furthermore, since the upper door body 118 does not cover the upper part of the front opening 123, there is no problem in putting in and out the object to be cleaned 125 such as tableware, and it is easy to use.

Further, the upper door support member 120 and the lower door support member 121 are connected by an interlocking portion 126. When the lower door body 119 is opened and closed, the upper door body 118 is also opened and closed in conjunction with each other. Since the opening 123 can be opened and closed, an easy-to-use dishwasher is realized. Further, the connecting portion between the upper door support member 120 and the interlocking portion 126 is configured to have play by a cylindrical connecting shaft 127 provided in the upper door support member 120 and a long hole portion 128 provided in the interlocking portion 126. After the door body 118 reaches the closed state, only the lower door body 119 is operated, and the locking means 129 provided on the lower door body 119 is locked to the side wall of the cleaning tank 122, whereby the upper door body 118, the lower door The body 119 is closed. As a result, the door-to-door seal member 130 attached to the upper door 118 can be sealed by the door-to-door seal receiver 131 provided on the lower door 119, and water leakage can be prevented.

  However, as in the conventional dishwasher described in Patent Document 2, the configuration in which the upper door body 118 and the lower door body 119 are opened and closed so as to overlap the front lower part of the front opening 123 is easy to install and use. Both are excellent, but since the distance L from the rotation center 132 of the upper door body 118 to the upper side of the upper door body 118 is long, the user mistakenly applies an external force F to the upper side of the upper door body 118 during operation. When added, there is a problem that the upper side of the upper door body 118 moves in the opening direction relatively easily and high-temperature washing water is ejected outside the apparatus.

  Further, when the upper door body 118 and the lower door body 119 are closed while the object to be cleaned 125 such as tableware jumps out of the tableware basket 124, the upper door body 118 and the object to be cleaned 125 come into contact with each other. Thus, even if the closing operation of the upper door body 118 is stopped in the incompletely closed state that has been lifted from the normal closing position, the lower door body 119 can be operated by the clearance of each connecting portion, so that the lower door body 119 is closed. And the problem that the seal of the upper door 118 is operated in an incomplete state.

  Furthermore, if the distance L is long, the clearance provided in the rotation center 132 and the long hole portion 128 is amplified, and the upper side of the upper door body 118 is greatly rattled. Further, there is a problem that the seal between the sealing member 133 and the upper door body 118 becomes unstable.

  SUMMARY OF THE INVENTION The present invention solves the above-described conventional problems, and an object of the present invention is to provide a high-quality dishwasher in which an upper door body is robust with respect to a front opening of a washing tank and has a stable seal.

In order to solve the above-mentioned conventional problems, the dishwasher of the present invention includes a main body having a cleaning tank, an upper door body and a lower door body that openably and closably open an opening provided on the front surface of the cleaning tank, An upper door support member, a lower door support member, and an upper door support member and a lower door support that are rotatably supported on the side wall of the cleaning tank and support the upper door body and the lower door body, respectively. An interlocking member that interlocks the members;
Locking means for holding the lower door body in the state where the opening is closed at the opening, and the upper door body and the lower door body are located at the front lower side of the cleaning tank and the inner surface sides of both. The upper door closing position restricting means for restricting the closing position of the upper door body is provided , and the upper door closing position restricting means is provided on the upper door body. An upper door restricting portion provided, an interlock restricting portion provided on the interlocking member, and a restricting member pivotally supported on a side wall of the cleaning tank, wherein the restricting member is formed of the upper door body. A first contact portion that contacts the upper door restricting portion and prevents the upper door body from being opened from a predetermined opening position to a closing position, and the upper door restricting portion and the first contact portion. those having the interlocking regulating portion and a second contact portion which abuts to rotate said regulating member in a direction to abut The upper door closing position restriction means can regulate the closing position of the upper door body, so even if an external force is applied to the upper door body with the upper door body and lower door body closed, the upper door The body does not move in the opening direction, and a safe and reliable seal can be realized.

  In the dishwasher of the present invention, the upper door body is robust with respect to the opening on the front surface of the washing tank, and a stable seal can be secured, thereby improving the quality of the dishwasher.

The first invention includes a main body having a cleaning tank, an upper door body and a lower door body that openably and closably open an opening provided on the front surface of the cleaning tank, and a pivotally supported on the side wall of the cleaning tank. And an upper door support member and a lower door support member that support each of the upper door body and the lower door body, an interlocking member that interlocks the upper door support member and the lower door support member, and the lower door Locking means for holding the body in the state where the opening is closed at the opening, and the upper door body and the lower door body are directed to the front lower side of the cleaning tank, and both inner surface sides face upward. The upper door closing position restricting means for restricting the closing position of the upper door body is provided , and the upper door closing position restricting means is provided on the upper door body. It is pivotally supported by a door restricting portion, an interlock restricting portion provided on the interlocking member, and a side wall of the cleaning tank. The restriction member comprises a restriction member, and the restriction member is in contact with the upper door restriction portion from the predetermined opening position of the upper door body to the closing position, and prevents the upper door body from being opened. And a second abutting portion that abuts the interlocking regulating portion so as to rotate the regulating member in a direction in which the upper door regulating portion and the first abutting portion abut. Since the closing position of the upper door body can be regulated by the door closing position regulating means, even if an external force is applied to the upper door body with the upper door body and the lower door body closed, the upper door body Does not move in the opening direction, and a safe and reliable seal can be realized. When the upper and lower doors are closed, the upper door body comes into contact with the object to be cleaned such as tableware and the upper door body due to the repulsive force of the seal member provided at the opening. Even if it stops, the upper door restricting part is pulled in the closing direction by the restricting member that is rotated by the interlocking restricting part, so the upper door body starts to move again in the closing direction, and the lower door body is locked to the opening. When this is done, the upper door can also be closed at the normal position.

In the second invention, in particular, the upper door support member of the first invention is urged in the closing direction of the upper door body, and a play is provided at the connecting portion between the interlocking member and the upper door support member. The lower door body can be moved by a predetermined amount in the opening direction relative to the upper door body, the upper door body can be closed in advance with respect to the lower door body, The restricting member can be operated after reaching the closed position or the vicinity of the closed position. When no play is provided at the connecting portion, the upper door restricting portion and the restricting member operate together in the vicinity of closing, and the upper door body is retracted while sliding at the first abutting portion. In addition, the malfunction of the upper door restricting portion and the restricting member is easily caused due to an error in parts processing or assembling. On the other hand, as in the present invention, by providing play in the connecting portion, the restricting member rotates and contacts the upper door restricting portion stopped at the normal position. Therefore, the operation order of the upper door restricting portion and the restricting member is defined, and a margin can be given to the operation setting, so that a smooth and stable closing operation can be realized.

The third invention has a structure that has play only when the upper door body of the second invention is in the closed state, and the upper and lower door bodies from the opened state to the vicinity of the closed state are interlocked. In the area to be opened and closed, the upper door body can be reliably closed before the lower door body, and a stable opening and closing operation can be realized. In other words, when play is provided at the connecting part of the interlocking member and the lower door support member in the entire area of the opening / closing operation, for example, during the closing operation of the upper / lower door body, due to the contact between the object to be cleaned and the upper door body, etc. When the closing operation is stopped before the upper door reaches the closed position, it becomes possible to move the lower door in the direction of closing, and the inner surface (waterproof ribs, etc.) of the lower door is attached to the outer surface of the upper door. Problems such as contact and dirtying or scratching the appearance of the upper door body occur. On the other hand, as described above, the upper door body cannot be operated when the upper door body is locked during the closing operation of the upper and lower door bodies as described above. It is possible to maintain the positional relationship in which the body is closed in advance, and the above-described problems can be solved without contact between the upper door body and the lower door body.

  The operation | movement and effect | action are demonstrated about the dishwasher in this Embodiment comprised as mentioned above.

  By pushing the push button switch 16, the locking means 18 is released from the locking portion 17, and the interlocking member 21 biased by the third spring 47 operates in the opening direction of the upper and lower door bodies 6, 7. To do. By operating the interlocking member 21, the restricting member 25 rotates while being in contact with the interlocking restricting portion 28 at the second contact portion 29.

  Due to the biasing force to the upper door support member 11 of the second spring 44 and the upper door retracting force to the upper door support member 11 of the upper door retracting member 33, only the lower door body 7 is opened at the initial stage of opening, and the upper door Since the body 6 remains in the closed position, the contact between the first contact portion 27 and the upper door restricting portion 26 is released by the rotation operation of the restricting member 25, and the closed position restriction of the upper door body 6 is achieved. Is released (from the state of FIG. 1 to the state of FIG. 3).

  In the present embodiment, the two doors 44 and the upper door retracting member 33 are configured so that the upper door body 6 remains in the closed position at the initial opening stage, but the weight of the upper door body 6 Depending on the constraints of the space into which the second spring 44 and the upper door retracting member 33 are incorporated, the upper door body 6 can be configured to remain in the closed position with only one of the mechanisms.

  When the cylindrical connecting shaft 20a moves through the play area in the long hole portion 20b, the cylindrical connecting shaft 20a and the long hole portion 20b are connected, and the upper door body 6 and the lower door body 7 operate in conjunction with each other.

  In accordance with the opening operation of the upper and lower door bodies 6 and 7, the upper door retracting member 33 moves upward, and when the upper and lower door bodies 6 and 7 are opened by a predetermined amount, the second guide rail 35 second The rail end point 35a contacts the second guide pin 32. When the upper and lower door bodies 6 and 7 are further opened, the upper door retracting member 33 uses the second guide pin 32 as a fulcrum and the first guide end point 34a of the first guide rail 34 and the first guide pin. It rotates until 31 contacts.

  When the upper door retracting member 33 rotates, the contact between the upper door retracting pin 36 and the upper door retracting protrusion 37 is released, and the upper and lower door bodies 6 and 7 are closed by the upper door retracting member 33. Is no longer energized.

  The upper door retracting member 33 is urged downward by the first spring 41, but the first guide pin 31 does not move downward because it protrudes from the upper surface of the first guide rail 34. It remains in the upper position as shown in FIG.

  The upper door retracting member 33 receives only the repulsive force from the seal member 8 and only needs to be closed from the vicinity of closing the door body, which requires a large closing force to close the upper door body 6 to the normal position. Since the door body closing force can be applied, the upper door body 6 is effectively closed to the normal closing position as compared with the configuration in which the urging force always acts in the closing direction like the second spring 44. Can be made. If the urging force in the predetermined closing direction is applied in the vicinity of the closing of the upper and lower door bodies 6 and 7 only by the second spring 44, the upper and lower door bodies 6 and 7 are opened in the middle of opening. The energizing force of the second spring 44 in the closing direction of the upper and lower door bodies 6 and 7 becomes too large, and a very large opening force is required to open the upper and lower door bodies 6 and 7. turn into.

  The upper door body 6 and the lower door body 7 are opened to an opened state where the upper door support member 11 and the lower door support member 14 are in contact with the first stopper portion 12 and the second stopper portion 15, respectively. At this time, the upper door body 6 and the lower door body 7 are opened so that the inner surfaces of both the upper door body 6 and the lower door body 7 are substantially horizontal upward and overlap each other (the upper door body 6 is positioned above).

After opening the upper and lower door bodies 6, 7, the tableware basket 4 is pulled out on the inner surface of the upper door body 6 and an object to be cleaned is set. Since the tableware basket 4 is pulled out on the inner surface of the upper door body 6, it is possible to prevent the juice and water droplets dripping from the article to be cleaned 3 such as tableware from flowing out of the machine. Further, unlike the conventional dishwasher, the upper door body 6 does not cover the upper portion of the opening 5, so that the work 3 can be easily set, and the upper surface of the main body 1 can be used as a storage space, which is very convenient. Is good. Furthermore, since the open space of the upper door body 6 is not required above the main body 1, the product installation is good.

  Then, the tableware basket 4 is accommodated in the washing tank 2 and the lower door body 7 is closed. Since the upper door body 6 and the lower door body 7 are configured to open and close in conjunction, the upper door body 6 is also closed simultaneously. Due to the urging force in the closing direction of the upper door body 6 to the upper support member 11 by the second spring 44 and the urging force in the door body closing direction to the interlocking member 21 by the third spring 47, the lower door body The starting force for closing 7 may be small, and the operation feeling is good.

  During the closing of the upper and lower door bodies 6, 7, rattling of the upper door body 6 due to play of the second connection point 20 is regulated by the guide hole portion 22 and the guide projection portion 23. The position of the upper door body 6 with respect to the door body 7 is stable without shaking. As a result, in the closing operation, the inner surface (waterproof rib or the like) of the lower door body 7 does not come into contact with the outer surface of the upper door body 6 and the appearance of the upper door body 6 is not soiled or damaged. In addition, since the predetermined operation of causing the upper door body 6 to reach the closed position prior to the lower door body 7 can be realized with certainty, the inter-door seal member 9 attached to the upper door body 6 is replaced with the lower door body 7. The door can be reliably sealed by the door-to-door seal receiver 7b.

  When the upper and lower door bodies 6 and 7 are closed to a predetermined position, the upper door pull-in pin 36 comes into contact with the upper door pull-in trigger portion 38, and when the upper and lower door bodies 6 and 7 are further closed, the upper door pull-in pin 36 The upper door retracting member 33 is rotated until the first guide pin 31 comes into contact with the third guide end point 34b of the first guide rail 34 with the second guide pin 32 as a fulcrum by the force applied from To do. As a result, the guide pin 31 does not protrude to the upper surface of the first guide rail 34, and the upper door retracting member 33 moves downward by the urging force of the first spring 41 to close the upper door retracting pin 36. You can pull in the direction.

  When the upper and lower door bodies 6 and 7 are closed, the interlocking restricting portion 28 comes into contact with the second contact portion 29 at a predetermined closing position, and when further closed, the restricting member 25 is The contact portion 27 starts to rotate in a direction approaching the upper door restricting portion 26. Subsequently, when the upper and lower door bodies 6 and 7 are closed, the upper door body 6 is closed in advance, and then, when the lower door body 7 is closed, the first contact portion 27 is the upper door regulating portion. 26, the closed position of the upper door body 6 is regulated.

  As described above, in the present embodiment, the restricting member 25, the upper door restricting portion 26, and the interlock restricting portion 28 constitute an upper door closing position restricting means for restricting the closing position of the upper door body 6. .

  In the vicinity of the closed position of the upper and lower door bodies 6 and 7, the upper door body 6 exerts a force in the opening direction due to the repulsive force from the seal member 8 and the set of the object 3 to be cleaned from the tableware basket 4. receive. If the biasing force in the closing direction of the upper and lower door bodies 6 and 7 of the second spring 44 and the pulling force for pulling the upper door body 6 of the upper door retracting member 33 are insufficient, the upper door body 6 The closing operation stops without closing to the position. However, in such a case, since the upper door body 6 is positioned in front of the normal closing position, the first contact portion 27 contacts the upper door regulating portion 26 before the lower door body 7 is closed, In conjunction with the subsequent closing operation of the lower door body 7, the regulating member 25 pulls the upper door regulating portion 26 in the closing direction of the upper door body 6, so that when the lower door body 7 is closed, the upper door body 6 Can be closed at the normal position, and a safe and reliable seal can be realized.

  Even if an external force is applied to the closed upper door body 6, the restricting member 25 restricts the operation of the upper door restricting portion 26 in the opening direction, so that it does not move in the opening direction. Therefore, it is possible to provide a dishwasher with high safety without causing hot washing water to be ejected outside the apparatus.
