Description

Technical Field

[0001] This invention relates to the field of dishwasher technology, and more particularly to a control method for a drawer-type dishwasher. Background Technology

[0002] In related technologies, drawer-type dishwashers have become the mainstream product in the domestic dishwasher market. The requirements for the reliability and usability of drawer-type dishwashers are getting higher and higher, and overflow detection has become an indispensable fault alarm function.

[0003] During or after the washing process in a drawer-type dishwasher, water inevitably remains on the top cover of the inner tub. After opening the door, the water remaining on the top cover will drip to the chassis due to vibration and gravity. If there is too much residual water, it will falsely trigger the overflow protection alarm. Even if the overflow protection alarm is not triggered, the residual water in the chassis will still cause corrosion and rust. Summary of the Invention

[0004] The present invention aims to at least partially solve one of the problems existing in the prior art. To this end, the present invention proposes a control method for a drawer-type dishwasher, which can solve to some extent the problems of false triggering of overflow protection fault alarm and chassis corrosion and rusting caused by water in the prior art.

[0005] The above objective is achieved through the following technical solution:

[0006] A control method for a drawer-type dishwasher, the drawer-type dishwasher including a shell, an inner liner, a cover, a pull plate, a pull rod, a slide rail, a reset device, a drive device, and a controller. The inner liner is disposed inside the shell, the cover is disposed above the inner liner, the cover, the pull plate, and the pull rod are connected sequentially, the reset device is disposed in the slide rail and contacts the pull rod, the pull rod can drive the cover to move through the pull plate, the reset device plays a reset role during the movement of the pull plate, the drive device is connected to the slide rail, and the controller is electrically connected to the drive device. The control method includes the following steps:

[0007] S1. Determine whether the washing program has been paused or ended. If yes, proceed to step S2. If no, repeat step S1.

[0008] S2 controls the cover plate vibration;

[0009] S3, determine whether the number of times the cover plate shakes has reached the preset number. If yes, proceed to step S4; otherwise, return to step S2.

[0010] S4, control the drive device to stop working.

[0011] In some implementations, step S2 includes:

[0012] S21, control the drive device to stop working for a first preset time;

[0013] S22, control the drive device to work for a second preset time;

[0014] In some implementations, when the control drive device stops working for a first preset time, the reset device resets and drives the pull plate to move upward via the pull rod. During the upward movement of the pull plate, the cover plate moves upward and vibrates.

[0015] In some embodiments, when the drive device operates for a second preset time, the drive device pulls the slide downward. When the slide moves downward, the reset device is compressed. At the same time, when the slide moves downward, the cover plate is driven to move downward through the pull rod and the pull plate.

[0016] In some implementations, the second preset time is longer than the first preset time.

[0017] In some implementations, the first preset time is 1-3 seconds, and the second preset time is 2-5 seconds.

[0018] In some implementations, the preset number of times is 2-5 times.

[0019] Compared with the prior art, the present invention has at least the following beneficial effects:

[0020] 1. This invention provides a control method for a drawer-type dishwasher, which can solve, to some extent, the problems of falsely triggering overflow protection alarms and water corrosion and rusting of the chassis in the prior art. Attached Figure Description

[0022] Figure 2 This is a partial schematic diagram of the drawer-type dishwasher in the embodiment;

[0023] Figure 3 This is a flowchart illustrating the control method in the embodiment. Detailed Implementation

[0024] The following embodiments illustrate the present invention, but the present invention is not limited to these embodiments. Modifications to the specific embodiments of the present invention or equivalent substitutions for some technical features, without departing from the spirit of the present invention, should all be covered within the scope of the technical solutions claimed in the present invention.

[0025] Example 1: As Figure 1 , Figure 2 and Figure 3As shown, this embodiment provides a control method for a drawer-type dishwasher. The drawer-type dishwasher includes a shell 1, an inner liner 2, a cover 3, a pull plate 4, a pull rod 5, a slide 6, a reset device 7, a drive device 8, and a controller. The inner liner 2 is disposed inside the shell 1, and the cover 3 is disposed above the inner liner 2. The cover 3, pull plate 4, and pull rod 5 are connected in sequence. The reset device 7 is disposed in the slide 6 and contacts the pull rod 5. The pull rod 5 can drive the cover 3 to move through the pull plate 4. The reset device 7 plays a reset role during the movement of the pull plate 4. The drive device 8 is connected to the slide 6, and the controller is electrically connected to the drive device 8. For details of the cover movement mechanism of the drawer-type dishwasher, please refer to patent CN209437196U. The control method includes the following steps:

[0026] S1. Determine whether the washing program has been paused or ended. If yes, proceed to step S2. If no, repeat step S1.

[0027] S2, controls the vibration of cover plate 3;

[0028] S3, determine whether the number of vibrations of cover plate 3 has reached the preset number. If yes, proceed to step S4; otherwise, return to step S2.

[0029] S4, control drive device 8 to stop working.

[0030] The control method for the drawer-type dishwasher provided in this embodiment can, to a certain extent, solve the problems of false triggering of overflow protection alarm and chassis corrosion and rust caused by water in the background art.

[0031] In this embodiment, step S includes:

[0032] S21, control the drive device 8 to stop working for a first preset time t1. When the controller controls the drive device 8 to stop working, the reset device 7 in the slide 6 springs back to reset, causing the cover plate 3 to shake once. The water droplets on the cover plate 3 fall into the inner liner 2 due to the shaking and gravity.

[0033] S22, control the drive device 8 to work for a second preset time t2. When the controller controls the drive device 8 to work and tightens the cover plate 3, it can make the reset device 7 have sufficient reset potential energy.

[0034] Specifically, when the control drive device 8 stops working for a first preset time, the drive device 8 releases the preload, the reset device 7 resets, and drives the pull plate 4 to move upward through the pull rod 5. During the upward movement of the pull plate 4, the cover plate 3 moves upward and vibrates.

[0035] When the control drive device 8 operates for the second preset time, the drive device 8 pulls the slide 6 downward. When the slide 6 moves downward, the reset device 7 is compressed. At the same time, when the slide 6 moves downward, the cover plate 3 is driven to move downward through the pull rod 5 and the pull plate 4.

[0036] The above structure is simple, reasonably and ingeniously designed, and works stably and reliably.

[0037] Preferably, the second preset time t2 is longer than the first preset time t1, so that the reset device 7 has sufficient reset potential energy. When the drive device 8 stops working, the cover plate 3 can shake fully to shake the water droplets on the cover plate 3 into the inner liner 2.

[0038] In this embodiment, the first preset time t1 is 1-3 seconds, and the second preset time t2 is 2-5 seconds. Preferably, the first preset time t1 is 1 second and the second preset time t2 is 3 seconds, which is a reasonable and ingenious design that can shake the water droplets on the cover plate 3 into the inner liner 2.

[0039] In this embodiment, the preset number of times is 2-5. Preferably, the preset number of times is 3, which is a reasonable and ingenious design that can shake the water droplets on the cover plate 3 into the inner liner 2, effectively avoiding the presence of residual water on the cover plate 3.

[0040] The specific implementation method of the drawer-type dishwasher control method provided in this embodiment is described below:

[0041] When the dishwasher pauses adding dishes during the wash cycle or removing dishes after washing, the door opens automatically or manually. The controller stops the drive unit 8. The reset device 7 within the slide 6 springs back, causing the lid 3 to vibrate once. Water droplets on the lid 3 fall into the inner tub 2 due to the vibration and gravity. One second later, the controller activates the drive unit 8 and tightens the lid 3, ensuring the reset device 7 has sufficient reset potential energy. This process repeats until the lid 3 vibrates three times, ensuring all water droplets fall into the inner tub 2. After the lid 3 vibrates three times, the controller stops the drive unit 8, and the dishwasher can then open the door. This prevents water droplets from falling onto the chassis, thus preventing overflow and protecting the chassis.

[0042] The above descriptions are merely some embodiments of the present invention. Those skilled in the art can make various modifications and improvements without departing from the inventive concept of the present invention, and these all fall within the scope of protection of the present invention.
