[0030] In order to make the technical problem solved by the present invention, the technical solution adopted and the technical effect achieved more clearly, the technical solution of the present invention is further explained below with reference to the accompanying drawings and through specific implementation methods.

[0031] This embodiment provides a dishwasher, which includes a drawer-type box structure, specifically, Figure 1 As shown, the drawer-type cabinet structure includes a cabinet 1 and a drawer 2 arranged in the cabinet 1. The cabinet 1 is the main part of the dishwasher. One side of the cabinet 1 is open, and the drawer 2 is arranged in the cabinet 1 through the opening. When the drawer 2 is pulled out of the cabinet 1, tableware can be put into the drawer 2, and then the drawer 2 is pushed into the cabinet 1. The end of the drawer 2 serves as a cabinet door to close the opening of the cabinet 1 so as to wash the tableware.

[0032] After the tableware is put into the drawer 2, the overall weight of the drawer 2 increases, and it is more laborious to manually pull it out or push it in. For the convenience of users, in this embodiment, by providing a push rod 4 and a drive assembly, the drawer 2 can be automatically pushed out of the box body 1 for a distance, which can reduce the force required for the user to open the drawer 2, making it convenient for users to use and reducing the difficulty of user operation. In addition, by opening the drawer 2 through the cooperation of the push rod 4 and the drive assembly, it can also avoid the tableware in the drawer 2 from colliding and being damaged due to excessive or violent operation by the user, and it can also avoid user injuries, which is conducive to improving the user experience.

[0033] Specifically, Figure 2 As shown, the push rod 4 is slidably arranged on the inner wall of the box body 1, and the push rod 4 can slide along the push-pull direction of the drawer 2, and the driving assembly is used to drive the push rod 4 to slide. In this embodiment, when the driving assembly drives the push rod 4 to slide to the outside of the box body 1, the push rod 4 will contact the drawer 2 and push the drawer 2 out of the box body 1, so as to realize the automatic opening of the drawer 2. In this embodiment, the initial stage of pulling the drawer 2 out of the box body 1 is automatically completed by the cooperation of the push rod 4 and the driving assembly, and the user does not need to apply a pulling force, which is convenient to operate; after the drawer 2 is pushed out of the box body 1, the user can fully open the drawer-type box structure by pulling the drawer 2. In this process, the user needs to apply less force, which is conducive to improving the user experience.

[0034] Specifically, the driving assembly includes a cam 3 and a motor 6. The motor 6 can be arranged inside the box 1. The cam 3 is connected to the motor 6. The motor 6 can drive the cam 3 to rotate. The position where the cam 3 is connected to the motor 6 is the rotation center, and the distances from the rotation center to the two ends of the cam 3 are not equal. The motor 6 is used to drive the cam 3 to rotate. When the drawer 2 needs to be opened, the motor 6 drives the cam 3 to rotate, and the outer contour of the cam 3 will abut against the push rod 4. As the cam 3 rotates, the push rod 4 is pushed out of the box 1, thereby pushing the drawer 2, and the drawer 2 is automatically opened.

[0035] In this embodiment, the distance that the drawer 2 moves out of the box body 1 by the push force of the push rod 4 does not need to be too long, and it is only necessary to ensure that the drawer 2 is pushed out of the box body 1 for a certain distance. In this embodiment, the initial stage of pulling the drawer 2 out of the box body 1 is automatically completed by the cooperation of the cam 3, the push rod 4 and the motor 6, and the user does not need to apply a pulling force, which solves the problem of the user needing to apply a large force in the initial stage of pulling out the drawer in the prior art, and the operation is convenient; when the drawer 2 is pushed out of the box body 1, the user can fully open the drawer-type box structure by pulling the drawer 2, and the force that the user needs to apply in this process is small, which is conducive to improving the user's experience.

[0036] In order to improve the automation of the drawer-type box structure, the drawer-type box structure may further include a controller, which is electrically connected to the drive assembly, and the controller may control the drive assembly to work, thereby automatically opening the drawer 2. The controller may include a control panel and a control circuit, and an operation button for opening or closing the dishwasher may be provided on the control panel. When the user needs to pull out the drawer 2, an operation instruction may be input through the control panel, and the operation instruction may be used to control the motor 6 to drive the cam 3 to rotate, thereby pushing out the drawer 2.

[0037] In order to prevent the push rod 4 from hindering the drawer 2 from closing when the user closes the drawer 2, in this embodiment, the push rod 4 also has an automatic reset function. Specifically, a slide groove 11 is provided on the inner wall of the box body 1 along the push-pull direction of the drawer 2, and the push rod 4 is slidably arranged in the slide groove 11, and a return spring 5 is also provided in the slide groove 11, and the two ends of the return spring 5 are respectively connected to the push rod 4 and the box body 1, and the elastic force of the return spring 5 can push the push rod 4 to slide toward the inside of the box body 1. When the controller controls the driving component to work so that the drawer 2 is pushed out of the box body 1, the motor 6 can be controlled to stop working, and the rotation angle of the cam 3 can be controlled or the motor 6 can be reversed so that the cam 3 no longer applies thrust to the push rod 4, and the push rod 4 will move toward the inside of the box body 1 under the action of the return spring 5 and return to the initial position, thereby avoiding interference with the drawer 2 being pushed into the box body 1.

[0038] In order to further ensure the smooth movement of the drawer 2, a guide structure may be provided in the dishwasher. The guide structure may be a slide rail and a slider matched with the slide rail. The slide rail is provided along the moving direction of the drawer 2. The slide rail may be provided on the inner wall of the housing 1, and the slider is provided on the outer wall of the drawer 2. The movement of the drawer 2 is guided by the cooperation of the slide rail and the slider to prevent the drawer 2 from deviating from the moving direction and causing the drawer 2 to get stuck. Of course, the slide rail may also be provided on the outer wall of the drawer 2, and the slider may be provided on the inner wall of the housing 1, which may also achieve the guiding effect on the movement of the drawer 2.

[0039] In order to facilitate the push rod 4 to push the drawer 2, Figure 3 As shown, an abutment portion 21 may also be provided on the outer wall of the drawer 2, and the abutment portion 21 is used to cooperate with the end of the push rod 4, that is, during the sliding process of the push rod 4, the end of the push rod 4 can apply force to the drawer 2 by abutting with the abutment portion 21, so as to push the drawer 2 out of the box body 1.

[0040] Specifically, a groove 211 is provided in the vertical direction on one side of the abutment portion 21 facing the push rod 4. When the push rod 4 rotates, the end of the push rod 4 can extend into the groove 211, thereby increasing the contact area between the push rod 4 and the abutment portion 21 and making the drawer 2 open more smoothly.

[0041] When the user continues to pull the drawer 2 out of the box body 1 or the push rod 4 is in the initial position, the push rod 4 will disengage from the groove 211. In order to facilitate the push rod 4 to slide out of the box body 1, the end of the push rod 4 cooperates with the groove 211, and the cross-sectional width of the groove 211 gradually decreases along the depth direction of the groove 211, that is, the opening width of the groove 211 is larger, and the end of the push rod 4 can easily extend into the groove 211.

[0042] In this embodiment, the drawer-type box structure also includes a limit assembly, which may include a sensor assembly, which is electrically connected to the controller, and the sensor assembly is used to detect whether the drawer 2 is pushed out of the box 1. When it is detected that the drawer 2 is pushed out of the box 1, the sensor assembly sends a signal to the controller, and the controller controls the motor 6 to stop rotating according to the received signal. Specifically, the sensor assembly can be a contact sensor or a non-contact sensor. Taking the non-contact sensor as an example, the sensor assembly includes a receiving end and a transmitting end, one of which is arranged on the inner wall of the box 1, and the other is arranged on the outer wall of the drawer 2. When the cam 3 pushes the drawer 2 out of the box 1 for a certain distance, the receiving end and the transmitting end are arranged relative to each other, and the sensor assembly sends a signal to the controller. At this time, the drawer 2 has been pushed out of the box 1, and the controller controls the motor 6 to stop working.

[0043] In order to improve the uniformity of force during the push-out process of the drawer 2, a push rod 4 and a drive assembly can be respectively provided on opposite sides of the drawer 2, and the two push rods 4 are symmetrically arranged. When the drawer 2 is opened, the two drive assemblies are driven simultaneously, so that the two push rods 4 operate synchronously, which is conducive to the stable and smooth withdrawal of the drawer 2 and avoids the drawer 2 from being offset and stuck.

[0044] The above contents are only preferred embodiments of the present invention. For ordinary technicians in this field, according to the concept of the present invention, there will be changes in the specific implementation methods and application scopes. The content of this specification should not be understood as limiting the present invention.
