Description

[0002] In recent years, with the increasing popularity of kitchen garbage disposals in households, various types of garbage disposals have appeared on the market. However, the control devices of existing kitchen garbage disposals are too simple in function. They directly drive the motor through the power supply, and the opening and closing of the garbage disposal motor, the control of the faucet, etc. are all independently controlled, which cannot achieve the linkage control of various functions.

[0003] Furthermore, although solutions for linking faucets and garbage disposals have emerged in the market, most of these solutions rely on wireless communication between the faucet and the garbage disposal. On the one hand, wireless communication requires pairing between the garbage disposal and the faucet, which is time-consuming and cumbersome. On the other hand, wireless communication is easily affected by external environmental interference, especially with the widespread use of smart kitchen and bathroom appliances. This results in various electrical grid harmonics and electromagnetic interference in the kitchen and bathroom environment, which can lead to wireless communication failure between the faucet and the garbage disposal, resulting in a high failure rate.

[0057] The technical solution of this utility model will be described in detail below with specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments.

[0058] As mentioned earlier, the existing control devices of kitchen waste disposers have overly limited functions. Furthermore, the waste disposer interacts with external devices via wireless signals from a wireless transmitter that applies control and a receiver that receives control signals. This typically requires a pairing process, which is often cumbersome for security reasons. Additionally, the wireless communication connection is unstable and susceptible to electromagnetic interference, leading to communication failures and other problems.

[0059] To address the aforementioned deficiencies, this utility model provides a wired-controlled garbage disposer controller, comprising a controller body and an electrical control module. The controller body includes a base and an upper housing, with the upper housing detachably connected to the base, forming an accommodating space between them. The electrical control module is disposed within this accommodating space and includes at least a main control chip, a wired communication module, a switching power supply module, a motor control module, an EMC protection circuit module, and a PCB board. The wired communication module is configured to establish a wired communication connection with the communication interface of an external device via a first cable, and monitors a first enable signal emitted by the external device. Based on the first enable signal, it controls the operating state of the motor connected to the wired communication module. The switching power supply module is configured to establish an electrical connection with the power supply interface of an external device via a second cable, thereby providing power to the external device. This utility model embodiment features a novel design, convenient operation, and perfectly solves problems such as electromagnetic interference from the external environment. It improves the stability and reliability of data transmission between devices, reduces error rates, and provides a superior user experience.

[0060] Figure 1 This invention illustrates the structure of a wired-controlled garbage disposal controller according to the present invention. Figure 1 ; Figure 2 This is a schematic diagram of the structure of a wired-controlled garbage disposer controller according to an embodiment of the present invention. Figure 2 ; Figure 3 This is a schematic diagram of the base and electrical control module of a wired-controlled garbage disposer controller according to an embodiment of the present invention. Figure 4 This is a schematic diagram of the device layout of an electronic control module according to an embodiment of the present invention.

[0061] like Figure 1 and 2 As shown, the garbage disposer controller 10 of this utility model realizes the electrical connection between devices based on wired control technology. The controller 10 includes at least two parts: a controller body 11 and an electrical control module 12, which is housed within the controller body 11.

[0062] Specifically,

[0063] The controller body 11 can be a box structure, consisting of a base 110 and an upper housing 111. The upper housing 111 is detachably connected to the base 110. A sealing waterproof gasket 112 is provided between the upper housing 111 and the base 110. When the upper housing 111 and the base 110 are installed and sealed, the waterproof gasket 112 is sandwiched in the middle to fill the gap generated during the installation of the upper housing 111 and the base 110, preventing water from entering the controller body 11, thereby increasing the waterproof performance. Furthermore, the upper housing 111 and the base 110 can be enclosed to form an accommodating space, within which the electronic control module 12 can be disposed. The upper housing 111 has at least a first opening 1110 and a second opening 1111 on its first side wall, and a third opening 1112 on its second side wall. Exemplarily, the first opening 1110 is used to install an external AC power socket, which is located near one edge of the PCB board and is used for AC power input. For example, the socket can be a three-prong female socket. The second opening 1111 is provided with a second socket for powering the garbage disposal motor, which can be a two-prong or three-prong male socket. The third opening 1112 is provided with a wired control socket, such as a Type-C female socket. Preferably, each socket is provided with a seal at the mounting point with the upper housing 111 to ensure that the controller can adapt to different operating conditions.

[0064] This disclosure, through the configuration design of the controller body, enables the controller to not only power the garbage disposal motor, but also meet the requirements for wired communication control between the controller and other external devices. Furthermore, the mounting openings are arranged on different side walls of the upper housing, ensuring the structural strength of the controller body while making the controller more flexible in use and adaptable to various complex installation spaces under the sink.

[0065] It should be noted that the external devices (not shown in the figure) in this disclosure may refer to electronic devices or other smart devices that can interact with the garbage disposal unit, such as electronic faucets or smart faucets or other automatic water supply devices, and this disclosure does not impose any special restrictions on them.

[0066] According to one embodiment of this disclosure, the electronic control module 12 includes at least a main control chip 120, a wired communication module 121, a switching power supply module 122, a motor control module 123, an EMC protection circuit module 124, and a PCB board 125. The main control chip 120, wired communication module 121, switching power supply module 122, motor control module 123, and EMC protection circuit module 124 are electrically connected to the PCB board 125 via pins. The main control chip 120, as the core control component of the controller, is responsible for coordinating and managing the overall operation of the equipment, such as data reading and writing control, system scheduling, interface connection, and signal processing. Preferably, the main control chip 120 uses a Telink TLSR8258 chip, which has Bluetooth communication capabilities and can wirelessly control the start and stop of the waste processor via a remote control (not shown in the figure).

[0067] The wired communication module 121 disclosed herein is configured to establish a wired communication electrical connection with the communication interface of an external device via a first cable, monitor a first enable signal emitted by the external device, and control the operating state of the motor connected to the wired communication module based on the first enable signal; and in response to the operating state of the garbage disposal unit's motor, to send control commands to the external device through the wired communication module. This wired communication method ensures that the linkage control between the controller and the external controlled device is not affected by unstable network conditions or network transmission delays, improving the stability of the linkage control, and enabling bidirectional communication between the garbage disposal unit and the external device through the wired communication module.

[0068] Specifically, the wired communication module 121 is integrated on the PCB board 125 and electrically connected to the main control chip 120. It mainly includes a microprocessor, a digital signal processor, a memory, I / O ports, and a wired communication power supply circuit. The microprocessor is configured to acquire a first enable signal output from an external device, and after data processing and protocol conversion of the first enable signal by the digital signal processor, it controls the execution of instructions. The memory stores communication parameters and temporary data. The I / O ports are used for data input / output interfaces, and the wired communication power supply circuit provides stable power to the wired communication module. This disclosure, by designing a wired communication circuit module to replace conventional wireless communication, offers several advantages. First, wired communication enables direct and quick interconnection between devices, eliminating the pairing process. Second, wired communication improves the stability and reliability of communication between devices and greatly enhances anti-interference capabilities. Furthermore, compared to other communication methods, wired communication modules are less expensive, thus reducing the overall cost of the controller.

[0069] Furthermore, in traditional wireless communication methods, the response time from the external device sending a control signal command to the waste processor receiving and executing the command is at least 2 seconds or longer. However, after switching to the wired control mode disclosed in this paper, it can support a higher data transmission rate and meet the application scenarios with high real-time requirements. For example, in response to the first enable signal triggered by the control action on the external device, the execution of the control command is completed within a preset time, where the preset time ranges from 30ms to 1s. It can be seen that the wired communication method greatly shortens the response time of device control, making the control more sensitive and providing a better user experience.

[0070] Preferably, the wired communication module 121 of this disclosure can be an RS-485 wired communication module with a baud rate of 9600 bit / s.

[0071] According to one embodiment of this disclosure, the switching power supply module 122 is configured to provide power to an external device by at least being electrically connected to its power supply interface via a second cable. In other words, the switching power supply module 122 can at least meet the power supply requirements of the external device, for example, it can provide power to an electronic faucet that is wired to the garbage disposal unit. It is understood that the switching power supply module 122 can also power the garbage disposal unit motor and provide power to the main control chip 120 of the controller 10 and other circuits.

[0072] For example, the switching power supply module 122 may include a power conversion circuit 1220, a first switching power supply module 1221, and a second switching power supply module 1222, wherein,

[0073] The power conversion circuit 1220 is used to convert the input external AC power into the DC power required by various circuits.

[0074] The first switching power supply module 1221 is configured to provide power to the motor of the waste disposer;

[0075] The second switching power supply module 1222 is configured to provide power to the main control chip and external devices.

[0076] The power conversion circuit 1220 includes a first circuit breaker, a varistor, a thermistor, a first common-mode inductor, and a first rectifier bridge. External AC power, such as 220V AC, can be rectified and regulated into DC power by the power conversion circuit to supply power to electrical equipment or components.

[0077] The first switching power supply module 1221 includes at least a thyristor, a second rectifier bridge, a relay, and a first power output interface. For example, an external AC power supply is rectified and regulated by the first switching power supply module 1221 to be converted into a first DC power supply with a first preset voltage amplitude. The first DC power supply is output through the first power output interface to power the garbage disposer motor. For example, the first preset voltage amplitude can be 300V. Of course, those skilled in the art can adjust the first preset voltage amplitude to other values ​​according to the actual needs of the electrical appliance, as long as the power demand is met. This disclosure does not impose any special limitations here.

[0078] Furthermore, the second switching power supply module 1222 includes a first capacitor, a primary-side feedback power management chip, a transformer, a second capacitor, an external device power output socket, and a primary-side control power switch. The external AC power supply, after being converted by the aforementioned power conversion circuit, forms a second DC power supply with a second preset voltage amplitude; preferably, this second preset voltage amplitude can be 300V. The second DC power supply, after being controlled and regulated by the primary-side feedback power management chip (e.g., a KP2126DP chip) and the transformer, generates a third DC power supply with a third preset voltage amplitude; preferably, this third preset voltage amplitude can be 12V, and the maximum output current can reach 2A. The third DC power supply can be directly used to power external devices through the external device power output socket. In addition, the third DC power supply can be converted into a fourth DC power supply with a fourth preset voltage amplitude through voltage regulation by the primary-side control power switch (e.g., a KP522201BLGA chip); preferably, this fourth preset voltage amplitude can be set to 3V for powering the main control chip.

[0079] According to the wired control-based garbage disposer controller disclosed herein, the signal input terminal of the wired communication module 121 of this disclosure can be integrated into the power output port 126 of the external device. Preferably, the power output port 126 of the external device can be designed as a Type-C socket. By connecting an external Type-C target cable, both wired communication connection to the external device and power supply requirements of the external device can be met.

[0080] Furthermore, the number of Type-C sockets can be one or more, for example, two Type-C sockets. Thus, the wired-controlled garbage disposer controller of this disclosure can simultaneously achieve wired control with two external devices, such as two electronic faucets, thereby realizing a one-to-two multi-branch control structure. This allows for the simultaneous connection of multiple external devices, facilitating controller expansion and maintenance, increasing the controller's application scenarios, and meeting the needs of different usage occasions. Compared to traditional wireless communication methods that can only achieve a one-to-one pairing mode, the wired control method of this disclosure increases the flexibility of application scenarios.

[0081] According to one embodiment of this disclosure, in order to further effectively suppress electromagnetic interference, the EMC protection circuit module 124 is arranged between the external AC power socket 127 and the switching power supply module 122. The EMC protection circuit module 124 may include devices such as a circuit breaker, an X2 capacitor, a Y capacitor, and a second common-mode inductor, so that the controller meets safety and electromagnetic compatibility requirements.

[0082] In addition, to control the speed of the garbage disposer motor, the motor speed can be controlled by controlling the conduction angle of the thyristor; at the same time, the conduction time of the thyristor is controlled according to the detected motor current to adapt to the load change. When the detected current exceeds the threshold, the motor is controlled to stop to protect the motor and control circuit.

[0083] Specifically, the wired-controlled garbage disposal controller of this disclosure may further include a current monitoring module 128 and a voltage regulation module. The current monitoring module 128 is arranged on the circuit path of the first switching power supply module 1221 and electrically connected to the main control chip 120. It is used to sample the motor current in real time. When the monitored sampled current value falls into a preset range of different load currents, the main control chip 120 can generate a corresponding voltage regulation control command based on the sampled current value to control the conduction angle time of the thyristor to adapt to load changes. This allows the garbage disposal controller to be adapted to the operation of garbage disposals of various models or power levels. For example, the controller of this disclosure can be adapted to garbage disposals with power levels of 300W, 450W, 600W, or 750W.

[0084] In other words, the garbage disposal controller disclosed herein can serve as a universal linkage controller, perfectly compatible with various models of garbage disposals. Compared to conventional garbage disposal control boxes, which can only be used with a single type of garbage disposal, the controller disclosed herein greatly saves costs and facilitates controller replacement and maintenance.

[0085] According to one embodiment of this disclosure, the wired-controlled garbage disposer controller further includes a remote controller, and the electronic control module 12 also includes a wireless communication module electrically connected to the main control chip 120. In response to a second enable signal sent by the remote controller, the wireless communication module can control the motor to perform a first action or a second action, and automatically trigger an external device electrically connected to the controller via wired communication to perform a third action or a fourth action. The first action can be turning on the motor, the second action can be turning off the motor, the third action can be automatically dispensing water from the external device, and the fourth action can be automatically shutting off the water from the external device.

[0086] As can be seen, on the one hand, this disclosure can send an enable signal to the garbage disposal controller via an external device that communicates with it via wired communication, causing the garbage disposal to interact with the external device (e.g., an electronic faucet). For example, by applying a control action to the electronic faucet, the faucet can automatically dispense water and simultaneously trigger the faucet to send a first enable signal to the garbage disposal controller. In response to the first enable signal, the garbage disposal controller receives and executes a control command, namely, controlling the garbage disposal motor to start. When the load current is detected to reach a preset range, the main control chip sends a stop command to the motor and simultaneously or later sends a water stop command to the external device. It is understandable that users can automatically stop the water flow by applying control to the electronic faucet again, and at the same time trigger the electronic faucet to send an enable signal to the garbage disposal unit to stop operation. On the other hand, this disclosure can also include a remote control, and the electronic control module is equipped with a wireless communication module. The remote control is wirelessly connected to the wireless communication module. In response to a second enable signal sent by the remote control, the wireless communication module controls the garbage disposal unit's motor to perform a start-up or shutdown operation, and automatically triggers the electronic faucet, which is wired to the controller, to perform a start-up or shutdown operation.

[0087] Optionally, the garbage disposal controller of this disclosure includes a remote control, and the main control chip 120 of the electronic control module can be a chip with Bluetooth communication function, so that the remote control can establish a Bluetooth communication connection with the main control chip 120. Then, the main control chip of the garbage disposal controller can control the garbage disposal motor to perform a first action or a second action in response to a third enable signal emitted by the remote control, and automatically trigger the electronic faucet to perform a third action or a fourth action. This disclosure can simplify circuit design and save costs by using a smart chip with Bluetooth communication function, thus eliminating the need for a wireless communication module.

[0088] Those skilled in the art will understand that the garbage disposal controller of this disclosure may further include a switch button, which is integrated on the control box body 11 and operably connected to the wired communication module. The switch button is configured to send a control signal to the garbage disposal after a control action is applied, and to send an enable signal to an external device within a predetermined time, thereby causing a linkage action between the garbage disposal and the external device.
