Detailed ways

The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and through specific implementation methods. It should be understood that the specific embodiments described here are only used to explain the present invention, but not to limit the present invention. In addition, it should be noted that, for the convenience of description, only the parts related to the present invention are shown in the drawings but not all of them.

As shown in Figures 1-5, this embodiment provides a door lock assembly, which is applied to a dishwasher, but is not limited to the dishwasher. The door lock assembly includes two door tongues 2 arranged on the liner 1, and the two door tongues 2 are connected by a connecting rod 3, and one end of the connecting rod 3 is connected with a push button 4 arranged on the control panel, and the The push button 4 is operated, and the pusher 31 at both ends of the connecting rod 3 pushes the door tongue 2 to move to realize the unlocking of the door body 5. At least one side of the door tongue 2 close to the pusher 31 is connected with a widened The panel 21 , when the door body 5 is in a closed state, the pushing member 31 is spaced apart from the door tongue 2 .

Figure 1 is a schematic diagram of the structure of the door body 5 in a closed state. There is a certain gap between the pusher 31 and the door tongue 2. When the door is opened, the door body 5 will not be locked. If there is no certain gap between the pusher 31 and the door tongue 2, then the pusher 31 is in contact with the door tongue 2, and the pusher 31 has the problem of blocking the reset of the door tongue 2, and the two springs connected to the door tongue 2 are in tension. As a result, the door tongue 2 cannot bounce back when the door is closed, and the micro switch cannot detect the signal that the door body 5 is closed, which in turn causes the dishwasher to fail to work normally. Therefore, a certain distance between the pusher 31 and the door tongue 2 The gap can solve the above problems. In this embodiment, the distance between the pusher 31 and the door tongue 2 is set at 1-1.5mm. During the opening process of the door body 5 , as the connecting rod 3 rotates, the end of the pushing member 31 away from the connecting rod 3 contacts the door tongue 2 . At this time, as shown in Figure 3 and Figure 4, an angle β is formed between the pusher 31 and the door tongue 2, and as the door body 5 is gradually opened, the angle β gradually becomes larger, and the angle range of its change is 3-12 °. When the pusher 31 is in contact with the door tongue 2, an included angle is formed between the two so that the door body 5 will not be locked when it is opened, and the door will be opened more powerfully with good hand feeling.

In order to avoid the problem that the pusher 31 does not contact the door tongue 2 due to the left and right movement of the connecting rod 3 when opening the door, thereby causing the door 5 to fail to open, in this embodiment, as shown in FIG. The pusher 31 is connected with a widened panel 21, the width of the side of the door tongue 2 in the prior art near the pusher 31 is 4mm, and the width of the added widened panel 21 is 3-5mm, preferably the widened panel 21 The width of the door tongue 2 is 4mm, and the width of the side of the side of the door tongue 2 close to the pusher 31 is increased to 7-9mm, preferably increased to 8mm. The door tongue 2 contacts to ensure that the door body 5 is opened smoothly.

Further, in order to strengthen the connection strength between the widened panel 21 and the door tongue 2, as shown in FIG. The wide panel 21 is connected, and the other end of the reinforcing rib 22 is connected with the door tongue 2 .

A push key 4 is provided near the side of the door tongue 2 where no widening panel 21 is added, and a driving member 32 is correspondingly provided 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 connecting rod 3, and the other end of the first rod 321 is connected to the second rod 322 , and there is an included angle between the second rod 322 and the first rod 321 . In order to further improve that when the door body 5 is opened, the door body 5 will not be locked, and to enable the user to have a suitable force angle when operating the push button 4, so that the surface of the push button 4 and the second rod 322 Set the included angle α. In this embodiment, when the door body 5 is in the closed state, the angle α between the surface of the pressing key 4 and the second rod 322 is set to 63°, and as the door body 5 is opened, the angle of the angle α gradually becomes larger , which varies in the range of 63-77°.

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

In this embodiment, one end of the first connecting rod 33 connected to the intermediate connecting rod 35 is provided with a connecting sleeve 36, and the end of the intermediate connecting rod 35 is placed in the connecting sleeve 36, and the connecting sleeve 36 is provided with a threaded through hole ( not shown in the figure), the position corresponding to the intermediate connecting rod 35 and the threaded through hole is provided with a connecting hole (not shown in the figure), and the first connecting rod 33 is connected to the intermediate connecting rod 33 through the threaded through hole and the connecting hole in turn by the bolt. Rod 35 is connected. The connection manner between the first connecting rod 33 and the intermediate connecting rod 35 is not limited to the above connection structure, and may also be other structures capable of realizing detachable connection, which will not be described here.

In this embodiment, one end of the second connecting rod 34 connected to the intermediate connecting rod 35 is provided with a connecting sleeve 36, and the end of the intermediate connecting rod 35 is placed in the connecting sleeve 36, and the connecting sleeve 36 is provided with a threaded through hole ( not shown in the figure), the middle connecting rod 35 is provided with a connecting hole (not shown in the figure) at the position corresponding to the threaded through hole, and the second connecting rod 34 is connected with the middle connecting rod 34 through the threaded through hole and the connecting hole in sequence. Rod 35 is connected. The connection manner between the second connecting rod 34 and the intermediate connecting rod 35 is not limited to the above connection structure, and may also be other structures capable of realizing detachable connection, which will not be described here.

This embodiment also provides a dishwasher, including the above-mentioned door lock assembly. The dishwasher with the door lock assembly will not have the problem of being unable to open or lock the door when opening the door, and will not have the problem that the door closing signal cannot be detected when the door is closed, thereby affecting the normal operation of the washing machine, which improves the user experience. satisfaction and comfort.

Apparently, the above-mentioned embodiments of the present invention are only examples for clearly illustrating the present invention, rather than limiting the implementation of the present invention. For those of ordinary skill in the art, other changes or changes in different forms can be made on the basis of the above description.
