Detailed Description

The technical scheme of the invention is further explained by the specific implementation mode in combination with the attached drawings. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some but not all of the elements associated with the present invention are shown in the drawings.

As shown in fig. 1-5, the present embodiment provides a door lock assembly for use in a dishwasher, but is not limited to a dishwasher. The door lock assembly comprises two door tongues 2 arranged on the inner container 1, the two door tongues 2 are connected through a connecting rod 3, one end of the connecting rod 3 is connected with a pressing key 4 arranged on a control panel, pushing pieces 31 at two ends of the connecting rod 3 push the door tongues 2 to move to unlock the door body 5 by operating the pressing key 4, the side surface of at least one door tongue 2 close to the pushing piece 31 is connected with a widening panel 21, and the pushing piece 31 and the door tongues 2 are arranged at intervals when the door body 5 is in a closed state.

Fig. 1 is a schematic structural diagram of the door 5 in a closed state, and a certain gap is formed between the pushing member 31 and the door tongue 2, so that the door 5 cannot be locked when the door is opened. If a certain gap does not exist between the pushing piece 31 and the door tongue 2, the pushing piece 31 is in contact with the door tongue 2, the pushing piece 31 has the problem of stopping the reset of the door tongue 2, two springs connected with the door tongue 2 are in a stretching state, so that the door tongue 2 cannot rebound when the door is closed, the micro switch cannot detect a signal for closing the door body 5, and further the dishwasher cannot normally work, and therefore, the problem can be solved by arranging the certain gap between the pushing piece 31 and the door tongue 2. In the present embodiment, the interval between the pusher 31 and the door tongue 2 is set to 1-1.5 mm. In the process of opening the door body 5, along with the rotation of the connecting rod 3, one end of the pushing piece 31 far away from the connecting rod 3 is contacted with the door tongue 2. At this time, as shown in fig. 3 and 4, an included angle β is formed between the pushing member 31 and the door tongue 2, and as the door body 5 is gradually opened, the angle β gradually increases, and the range of the change angle is 3 to 12 °. When the pushing piece 31 contacts the door bolt 2, an included angle is formed between the pushing piece and the door bolt, so that the door body 5 cannot be locked when being opened, and the door is more forced to open and has good hand feeling.

In order to avoid the problem that the pushing member 31 does not contact the latch 2 and further the door body 5 cannot be opened when the door is opened due to the left and right movement of the connecting rod 3, in the present embodiment, as shown in fig. 5, the pushing member 31 far away from the pressing key 4 is connected with the widening panel 21, the width of the side surface of the latch 2 close to the pushing member 31 in the prior art is 4mm, the width of the additionally arranged widening panel 21 is 3-5mm, preferably the width of the widening panel 21 is 4mm, and the width of the side surface of the latch 2 close to the pushing member 31 is increased to 7-9mm, preferably 8mm, so that even if the connecting rod 3 slightly moves in the left and right direction, the pushing member 31 will contact the latch 2, and the door body 5 is ensured to be opened smoothly.

Further, in order to enhance the connection strength between the widening panel 21 and the latch 2, as shown in fig. 2, a plurality of reinforcing ribs 22 are connected to the widening panel 21 on the side away from the pushing member 31, one end of each reinforcing rib 22 is connected to the widening panel 21, and the other end of each reinforcing rib 22 is connected to the latch 2.

The pressing key 4 is arranged on one side of the door bolt 2 without additionally arranging the widening panel 21, and the driving piece 32 is correspondingly arranged on the connecting rod 3. In this embodiment, the driving member 32 includes a first rod 321 and a second rod 322, one end of the first rod 321 is connected to the link 3, the other end of the first rod 321 is connected to the second rod 322, and an included angle is formed between the second rod 322 and the first rod 321. In order to further improve that the door body 5 is not locked when the door body 5 is opened, and the user has a proper force application angle when operating the pressing key 4, an included angle α is set between the surface of the pressing key 4 and the second rod 322. In this embodiment, when the door 5 is in the closed state, the angle α between the surface of the push key 4 and the second lever 322 is set to 63 °, and as the door 5 is opened, the angle α gradually increases and changes within the range of 63-77 °.

As shown in fig. 5, the link 3 includes a first link 33 and a second link 34, and an intermediate link 35 connecting the first link 33 and the second link 34, and the first link 33 and the second link 34 are detachably connected to the intermediate link 35, respectively. The connecting rod 3 is arranged into three detachable parts, when any part is damaged, the connecting rod is convenient to replace, and the maintenance cost is reduced.

In this embodiment, a connection sleeve 36 is disposed at one end of the first link 33 connected to the intermediate link 35, an end of the intermediate link 35 is disposed in the connection sleeve 36, a threaded through hole (not shown) is formed in the connection sleeve 36, a connection hole (not shown) is formed in a position of the intermediate link 35 corresponding to the threaded through hole, and the first link 33 and the intermediate link 35 are connected by a bolt sequentially passing through the threaded through hole and the connection hole. The connection mode of the first link 33 and the intermediate link 35 is not limited to the above connection structure, and may be other structures capable of realizing detachable connection, which will not be described herein.

In this embodiment, a connection sleeve 36 is disposed at one end of the second link 34 connected to the intermediate link 35, an end of the intermediate link 35 is disposed in the connection sleeve 36, a threaded through hole (not shown) is formed in the connection sleeve 36, a connection hole (not shown) is formed in a position of the intermediate link 35 corresponding to the threaded through hole, and the second link 34 is connected to the intermediate link 35 by passing through the threaded through hole and the connection hole in sequence through a bolt. The connection manner of the second link 34 and the intermediate link 35 is not limited to the above connection structure, and may be other structures capable of realizing detachable connection, which will not be described herein.

The embodiment also provides a dishwasher, which comprises the door lock assembly. The dish washer with this lock subassembly can not appear not opening or the dead problem of lock when opening the door, can not appear detecting the signal of closing the door when closing the door, and then influences the problem of washing machine's normal work, has improved satisfaction and the comfort level that the user used.
