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 of users, the size of the feeding port is too small, which brings inconvenience to feeding to a large extent. In addition, in order to prevent the kitchen waste from splashing during the grinding work of the kitchen waste disposer, a splash guard is usually designed in the installation component, and the setting of the splash guard is more troublesome for feeding.

[0003] In addition, there are two solutions for water storage and drainage of mainstream sink products on the market at this stage. The first solution is to manually place or lift the sink drain cover to realize the water storage and drainage functions of the sink. This solution has the problem of manually placing the cover when storing water, and the hands are wet when inverted. When draining, the hands need to be stretched into the sewage to pull the cover, causing the hands to get dirty; the other solution is to realize the water storage and drainage functions of the sink by mechanical or electric means. The electric water storage and drainage functions are designed for the sink itself. While avoiding the dirt and soaking of hands caused by water storage and drainage, the reliability of its use is increased through the coordinated design of electronic control and electrical appliances, which improves the overall user experience of the sink for users. The above existing solutions do not have a fast drainage function in terms of drainage function, and only rely on the natural drainage of water by gravity, which is easy to cause slow drainage. In addition, when water needs to be stored, the drainage channel cannot be flushed and cleaned, and the smoothness of the channel cannot be guaranteed. When processing kitchen waste, it does not have an automatic water diversion function. 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 realizes automatic water diversion function in the kitchen waste treatment working state and can flush the drainage channel when storing water, 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 disposal system with a high degree of intelligence and capable of effectively controlling water storage, drainage and a kitchen waste disposer 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, 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 interface is opened on the side of the grinding cover, a water outlet is opened at the bottom of the water tank, the water outlet is connected with the water inlet interface through a drainage channel, the drainage channel has a water inlet and a water inlet valve for controlling the opening and closing of the water inlet, a valve plate is installed inside the drainage channel, and the valve plate opens and closes the drainage channel under the drive of the valve plate motor.

[0008] Further preferably, the water inlet is provided at the bottom of the drainage channel and arranged horizontally.

[0009] In order to guide the water flow to expand the spraying area, a guide rib is provided downstream of the water inlet to disperse the water flow flowing into the water inlet to both sides of the water inlet direction.

[0010] In order to prevent kitchen waste from splashing back into the sink, a feeding cover is installed at the main feeding port.

[0011] Further preferably, the kitchen waste disposal system also includes a controller and a sensor for sensing the opening and closing state of the feeding cover, the signal output end of the sensor is electrically connected to the signal input end of the controller, and the signal output end of the controller is electrically connected to the valve plate motor, the drive motor and the water inlet valve. In this way, in order to ensure that the machine cannot run when the feeding cover is opened, to ensure safety, the cover is opened in coordination with the sensor under the sink, and at the same time to prevent the kitchen waste disposer from splashing into the sink through the lower return device during operation.

[0012] In order to realize automatic drainage, a water storage switch and a drainage switch are also included, and the water storage switch and the drainage switch are electrically connected to the signal input terminal of the controller. 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.

[0013] 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.

[0014] In order to allow the kitchen waste entering from the water inlet interface to enter the grinding disc for processing, the water inlet interface is arranged above the grinding disc.

[0015] In order to improve the drainage function, a pump wheel is installed below the grinding disc and rotates synchronously with the grinding disc.

The valve plate reaches the specified fully closed position, the drainage channel is closed, and the water storage function is realized. Then the drainage switch is started, the valve plate motor and the garbage disposal motor rotate synchronously, and the forced drainage function is started.
