Description

Technical Field

[0001] The present invention relates to the technical field of garbage disposal, and in particular to a kitchen waste disposal system and a control method thereof. Background Art

[0002] With the implementation of the garbage classification policy, the sales of classified garbage bins and garbage disposers have greatly increased, and kitchen waste disposers have been purchased and used by more and more customers. At present, there are various types of kitchen waste disposers, among which the direct-discharge type garbage disposers directly discharge the garbage into the sewer by crushing it, which brings certain convenience to users. The existing kitchen waste disposers are usually fixed to the water outlet of the sink through the installation component, and the kitchen waste in the sink enters the kitchen waste crushing chamber through the water outlet of the original sink for crushing. Since the diameter of the water outlet of the sink is usually 110mm, after the installation component is installed, the actual through-hole diameter is about 85mm. Most of the existing kitchen waste disposers are designed and manufactured according to the size of the water outlet. In the actual use process of users, the size of the feeding port is too small, which brings inconvenience to feeding to a large extent.

[0003] In addition, there are currently two solutions for water storage and drainage of mainstream sink products on the market. The first solution is to manually place or lift the sink drain cover to achieve the water storage and drainage functions of the sink. This solution requires manual placement of the cover when storing water, which causes the hands to get wet when inverted. When draining water, the hands need to be inserted into the sewage to pull the cover, causing the hands to get dirty. The other solution is to achieve the water storage and drainage functions of the sink through mechanical or electric means. The electric water storage and drainage functions are designed for the sink itself. While avoiding dirt and soaking of the hands caused by water storage and drainage, the reliability of its use is increased through the coordinated design of electronic control and electrical appliances, thereby improving the overall user experience of the sink. The above existing solutions do not have a fast drainage function in terms of drainage, and only rely on the natural drainage of water by gravity, which is prone to cause slow drainage. Summary of the invention

[0004] The first technical problem to be solved by the present invention is to provide a kitchen waste treatment system that can achieve rapid drainage in response to the above-mentioned existing technical status.

[0005] The second technical problem to be solved by the present invention is to provide a control method for a kitchen waste treatment system with a high degree of intelligence and capable of achieving strong drainage of the sink in response to the above-mentioned existing technical status.

[0006] The technical solution adopted by the present invention to solve the above-mentioned first technical problem is: the kitchen waste treatment system includes a water tank and a garbage disposer installed at the bottom of the water tank, the garbage disposer includes a grinding cover and a grinding disc arranged in the grinding cover, and a driving motor for driving the grinding disc to rotate is installed under the grinding cover. It is characterized in that: a main feeding port is opened on the water tank, the top of the grinding cover is installed on the main feeding port, a water inlet is opened on the side of the grinding cover, and a water outlet is opened at the bottom of the water tank, the water outlet is connected with the water inlet through a drainage channel, and a drainage mechanism for opening and closing the drainage channel is installed on the drainage channel.

[0007] The water discharge mechanism can have a variety of structures. Preferably, the water discharge mechanism includes a valve plate motor and a valve plate. The valve plate motor is installed on the outer wall of the drainage channel. The output shaft of the valve plate motor extends into the drainage channel. The valve plate is arranged in the drainage channel and installed on the output shaft of the valve plate motor. In this way, the valve plate rotates under the drive of the valve plate motor to open and close the drainage channel.

[0008] In order to realize automatic drainage, a water storage switch, a drainage switch and a controller are also included. The water storage switch and the drainage switch are electrically connected to the input end of the controller, and the output end of the controller is electrically connected to the valve plate motor and the drive motor. In this way, after the controller receives the drainage signal, the controller controls the valve plate motor and the drive motor to rotate, the valve plate opens, and the water in the drainage channel is sucked into the garbage disposer and discharged to the outside.

[0009] As another preferred solution, a water level sensor is installed in the drainage channel, and the signal output end of the water level sensor is electrically connected to the controller, and the controller can control the valve plate motor and the drive motor to rotate according to the output signal of the water level sensor received. In this way, the water level of the drainage channel can be detected by the water level sensor, and then the controller can control the valve plate motor and the drive motor to operate according to the water level.

[0010] In order to limit the valve plate in a closed state, a stopper is protruding from the inner wall of the drainage channel. When the valve plate is in a closed state, the edge of the valve plate abuts against the stopper.

[0011] In order to allow the kitchen waste entering from the water inlet to enter the grinding disc for processing, the water inlet is arranged above the grinding disc.

[0012] In order to improve the drainage function, a pump wheel is installed below the grinding disc and rotates synchronously with the grinding disc.

[0013] In order to discharge the ground processed garbage through the drain port, a drain port is provided on the grinding cover of the garbage disposer, and the drain port is located below the grinding disc.

[0014] In order to improve the convenience of feeding and user experience, a step structure is formed at the bottom of the water tank, the main feeding port is opened at the top of the step structure, and the water outlet is arranged at the lower part of the side of the step structure.

[0015] Preferably, a feeding cover is installed at the main feeding port. When the user needs to feed, the feeding cover can be opened to directly feed the whole plate. When the feeding cover is opened, the machine cannot run, ensuring safety and preventing kitchen waste from splashing.

[0016] The technical solution adopted by the present invention to solve the above-mentioned second technical problem is: the control method of the kitchen waste treatment system first opens the valve plate completely and turns on the water storage switch, then closes the valve plate and starts to store water, and after the water storage is completed, turns on the drain switch to drain the water, the valve plate motor drives the valve plate to open and drives the motor to rotate synchronously, and finally, after the valve plate is fully opened, rotates the valve plate in the opposite direction, judges the water level of the sink by reading the current of the valve plate motor, and decides whether to continue draining according to the water level.

[0017] Further preferably, the control method comprises the following steps:

[0018] s1. Obtain the default current Im when the valve plate is fully open, the current -Im when the valve plate is fully closed, and the no-load current Ik of the valve plate motor, and start the machine;

[0019] s2, detect the valve plate position signal and obtain the current valve plate motor current i;

[0020] s3, judge whether i≥Im is established,

[0021] If yes, proceed to step s4;

[0022] If not, the valve plate motor rotates and returns to step s3;

[0023] s4. The power-on self-test is completed, the valve plate reaches the specified fully open position, the drainage channel is fully opened, and the valve plate motor stops rotating;

[0024] s5, water storage switch starts;

[0025] s6, the valve plate motor rotates, and the current valve plate motor current i is obtained;

[0026] s7. Determine whether i≤-Im holds.

[0027] If yes, the valve plate reaches the specified fully closed position, the drainage channel is closed, the water storage function is realized, the valve plate motor stops rotating, and then enters step s8;

[0028] If not, the valve plate motor rotates and returns to step s7;

[0029] s8, drainage switch starts;

[0030] s9, the valve plate motor rotates, the current valve plate motor current i is obtained, the drive motor rotates synchronously, and the forced exhaust function is started;

[0031] s10, judge whether i≥Im is established,

[0032] If yes, the valve plate motor stops rotating and then enters step s11;

[0033] If not, the valve plate motor rotates and returns to step s10;

[0034] s11, the valve plate motor rotates, and the current valve plate motor current i is obtained;

[0035] s12. Determine whether i satisfies Ik﹤i﹤Im,

[0036] If yes, the valve plate motor stops rotating, the drive motor rotates, the forced exhaust function continues, and then returns to step s12;

[0037] If not, it is determined that the water in the drainage channel is about to be drained, the driving motor stops rotating, the forced drainage function stops, and then the process goes to step s13;

[0038] s13, end.
