Description

Technical Field

[0001] The invention belongs to the field of kitchens, and in particular relates to an intelligent sink filtering device and a control method. Background Art

[0002] In the kitchen field, the sink filter device aims to filter out impurities and prevent kitchen water pipes from being blocked while taking into account the fluidity of water.

[0003] At present, most of the sink filters on the market use traditional single-layer cylindrical filters with holes, which have limited ability to filter impurities of different sizes. Some sink filters take the problem of impurity filtering into consideration and use double-layer cylinders or screens for double filtration, but this design is insufficient for the research on the intelligentization of the kitchenware industry, and it is more difficult to clean the traditional double filtration device after impurities accumulate. The use of screens can solve this problem to a certain extent, but the screens need to be replaced constantly, which also brings certain troubles.

[0004] Therefore, in order to solve such problems, it is necessary to design an intelligent water tank filtering device, which can provide a more effective solution to such problems. Summary of the invention

[0005] In order to overcome the deficiencies of the prior art, the purpose of the present invention is to solve the problem of poor impurity filtering effect of a water tank filter device and automatically clean up impurities, and to design an intelligent water tank filter device and a control method.

[0006] In order to solve the above technical problems, the technical solution adopted by the present invention is:

[0007] An intelligent water tank filtering device comprises a water tank, a double-layer filtering device, a drain pipe, a garbage conveyor belt and a garbage recycling box;

[0008] The double-layer filtering device comprises an outer liner, an inner liner and an electric brake pad. The outer liner comprises an outer liner head, an outer liner side wall, an outer liner bottom plate and impurity filtering holes. The outer liner head is a circular ring structure with a larger top and a smaller bottom. The outer diameter of the top is larger than the diameter of the drain port in the sink, thereby fixing the double-layer filtering device. The outer liner bottom plate is an elliptical structure. The outer liner side wall connects the outer liner head and the outer liner bottom plate. The outer liner comprises an outer liner head, an outer liner side wall and an outer liner bottom plate, all of which are provided with a plurality of impurity filtering holes.

[0009] The inner liner includes an inner liner head, an inner liner side wall, an inner liner bottom plate and impurity filtering holes. The top of the inner liner head is connected to the top of the outer liner head by spot welding. The inner liner head is a nearly circular ring structure with a larger top and a smaller bottom. The outer diameter of the top is smaller than the outer diameter of the top of the outer liner head, and the outer diameter of the bottom is smaller than the radius of the bottom of the outer liner head. The inner liner bottom plate is an elliptical structure. The inner liner side wall connects the inner liner head and the inner liner bottom plate. The inner liner includes a plurality of impurity filtering holes distributed on the inner liner head, the inner liner side wall and the inner liner bottom plate.

[0010] The electric gate is a stretched arc structure, the arc radius is equal to the drain pipe, and the bottom profile is the same as the bottom plate of the inner tank. The electric gate can be controlled to open and close by the current converted by the digital signal processing device;

[0011] The garbage conveyor belt is a conveyor belt structure, with two sides slightly higher than the middle, forming a "concave"-shaped structure. One end of the garbage conveyor belt is connected to the bottom end of the electric gate of the double-layer filtering device, and the other end is connected to the garbage collection box.

[0012] The impurity filtering holes of the double-layer filtering device have a radius of R1 for the outer liner and a radius of R2 for the inner liner, 2R1=R2, thereby retaining large impurities in the inner liner and small impurities in the outer liner.

[0013] The inclination angles of the outer tank bottom plate and the inner tank bottom plate of the double-layer filtering device are α and β respectively, and 75°>β>α>45°.

[0014] The double-layer filtering device is also provided with a gravity sensor at its bottom. The gravity signal G(t) collected by the gravity sensor will be transmitted to the digital signal processing module through the gravity signal conversion module after A / D conversion to form a current I(t) to control the opening and closing of the gate.

[0015] The water tank is provided with a controller at the faucet switch, and the faucet opening and closing signal is transmitted to the digital signal conversion module to form a current I(t).

[0016] The inner tank side wall and the outer tank side wall of the double-layer filtering device are both opened at one end close to the gate, and the opening is consistent with the profile of the electric brake piece, so as to ensure the installation of the electric brake piece;

[0017] The drainage pipe is a circular tube structure with an open top and the same profile as the electric gate piece, so as to ensure the installation of a double-layer filtering device.

[0018] A control method for an intelligent water tank filter device, the specific signal collection, conversion, and processing steps in the working state are as follows:

[0019] (1) When the gravity sensor probe receives the gravity signal G(t) from the double-layer filter device, it is converted into an electrical signal I(t) through the gravity signal conversion module A / D conversion;

[0020] (2) The electrical signal I(t) output by the gravity signal conversion module is transmitted to the digital signal processing device;

[0021] (3) The electric signal I(t) is transmitted to the digital signal processing device of the control module, and I'(t) is defined as the critical current signal strength for valve opening. If I(t) ≥ I'(t), the signal processing device transmits I1 to the gate controller; if I(t) < I'(t), the signal processing device transmits I2 to the gate controller, where I1 indicates that the gate controller controls the electric gate to open, and I2 indicates that the gate controller controls the electric gate to close.

[0022] (4) At the same time, if the faucet is turned on, its controller will transmit the opening and closing signal A(t) to the digital signal processing device, and the digital signal processing device will receive this signal and transmit I2 to the gate controller, at which time the electric gate is closed.

[0023] The beneficial effects of the present invention are embodied in:

[0024] (1) The double filter outer and inner liner design is adopted to filter impurities of different sizes, thus improving the filtering effect;

[0025] (2) The outer and inner tanks are designed with inclined bottom plates, so that impurities are affected by their own gravity and enter the garbage recycling box along the garbage conveyor belt after the electric gate is opened;

[0026] (3) The control system intelligently monitors the quality of impurities by monitoring gravity. When a certain weight is reached, the electric gate is opened to prevent the double filter device from being blocked;

[0027] (4) When the faucet is turned on, the electric gate is forced to close to prevent water from flowing into the garbage collection bin; BRIEF DESCRIPTION OF THE DRAWINGS
