Description

Technical Field

[0001] This disclosure relates to the field of dishwasher technology, and more particularly to a dishwasher, a smart home system, and a lighting control method. Background Technology

[0002] A dishwasher is a device that automatically cleans tableware such as bowls, chopsticks, plates, dishes, knives, and forks. It achieves cleaning by spraying water under high temperature and pressure to thoroughly rinse the surface of the tableware, greatly improving efficiency. The high temperature environment effectively kills bacteria, ensuring the tableware is clean and hygienic.

[0003] Currently, most dishwashers lack internal lighting or have only low-wattage lights, resulting in poor illumination inside the dishwasher, making it inconvenient for users to handle dishes and leading to a poor user experience. While some technologies incorporate multiple lights inside the dishwasher to improve brightness and coverage, this also increases the design and manufacturing costs. Summary of the Invention

[0004] To address at least one of the aforementioned technical problems, this disclosure provides a dishwasher, a smart home system, and a lighting control method.

[0005] According to some embodiments of this disclosure, a dishwasher is provided, comprising: A housing, wherein a cleaning chamber is provided inside the housing; The door body is rotatably connected to the housing. A flip assembly is provided on the side of the door body near the housing. A reflective element is rotatably connected to the flip assembly. The flip assembly is used to rotate the reflective element when the door body is in the open state so that the reflective element reflects the light from an external light source into the cleaning chamber. The control module includes a controller and a communicator. The controller is connected to the flipping component and the communicator, respectively. The communicator is used for wireless communication with an external light source.

[0006] Based on the above solution, the dishwasher has a flip-up reflective element installed on the inside of the door. When the dishwasher door is opened, the reflective element can reflect the light from the external light source into the dishwasher, so that the dishwasher can ensure the lighting effect inside the washing chamber without increasing the cost of lighting.

[0007] In some possible implementations, a light intensity detection module is provided inside the cleaning chamber, which is used to detect the light intensity inside the cleaning chamber.

[0008] Based on the above solution, by detecting the light intensity inside the cleaning chamber through the light intensity detection module, the angle of the rotating reflector of the flip assembly can be adjusted, thereby improving the brightness and coverage inside the cleaning chamber and improving the lighting effect.

[0009] In some possible implementations, the flipping component includes: A drive motor, the output shaft of which is connected to a rotating shaft, and the reflective element having a mounting hole that is interference-fitted with the rotating shaft; The first angular displacement sensor is used to detect the angle between the reflective element and the side plane of the door body near the housing.

[0010] Based on the above solution, the flipping component includes a drive motor and a first angular displacement sensor. The first angular displacement sensor can detect the flipping angle of the reflective element, enabling the dishwasher to determine the angle with the greatest light intensity and improve control precision.

[0011] In some possible implementations, a second angular displacement sensor is also provided on the side of the door body near the housing, the second angular displacement sensor being used to detect the opening and closing angle of the door body.

[0012] Based on the above solution, the second angular displacement sensor of the door can accurately obtain the opening and closing angle of the door and feed it back to the controller. The controller can control the rotation speed and angle of the reflective element according to the opening and closing angle of the door, so as to avoid the reflective element from colliding with the shell and being damaged.

[0013] According to some embodiments of this disclosure, a smart home system is also provided, including a range hood and a dishwasher as described in any of the above embodiments. The range hood is located above the dishwasher, and a lighting module is provided at the bottom of the range hood. The lighting module illuminates the dishwasher. A communication module is provided in the range hood, and the range hood is wirelessly connected to the dishwasher through the communication module.

[0014] Based on the above scheme, the range hood and dishwasher are connected in communication. The dishwasher can send a signal to the range hood to turn on the lighting module, thereby realizing linkage lighting control.

[0015] In some possible implementations, the illumination direction of the lighting module is adjustable.

[0016] Based on the above solution, when the range hood is working, the lighting module is biased towards the stovetop, and when the range hood is not working, the lighting module is biased towards the dishwasher, which can improve flexibility.

[0017] According to some embodiments of this disclosure, a lighting control method is also provided, applied to a dishwasher in a smart home system described in the above embodiments, the method comprising: When the dishwasher door is detected to be open, a communication connection is established with the range hood in the smart home system; If the lighting module of the range hood is not lit, control the lighting module to turn on; Control the tumbler assembly in the dishwasher to rotate the reflector to a preset angle.

[0018] Based on the above solution, the dishwasher automatically connects to the range hood and controls the lighting module to turn on after the door is opened, and then controls the reflector to turn on, thereby completing the lighting of the dishwasher's cleaning chamber.

[0019] In some possible implementations, a light intensity detection module is provided inside the cleaning chamber of the dishwasher to detect the light intensity inside the cleaning chamber, and the flipping assembly includes a first angular displacement sensor to detect the angle of the reflective element. After controlling the tumble assembly in the dishwasher to rotate the reflector to a preset angle, the method further includes: The flipping component is controlled to rotate the reflective element step by step, and light intensity data is recorded. The light intensity data represents the light intensity in the cleaning chamber at each step angle of the reflective element. Based on the light intensity data, a target angle is determined, wherein the target angle represents the angle of the reflective element when the light intensity in the cleaning chamber is at its maximum. Control the flipping assembly to rotate the reflective element to the target angle.

[0020] Based on the above scheme, by controlling the step rotation of the reflective element, the light intensity and angle can be associated and stored, which makes it easier to accurately determine the target angle corresponding to the maximum light intensity.

[0021] In some possible implementations, the illumination module's light direction is adjustable, and controlling the flipping component to step-rotate the reflective element and record light intensity data includes: The flipping component is controlled to rotate the reflective element step by step. During the time interval between two step rotations of the reflective element, the lighting module is controlled to adjust the direction of illumination and record the light intensity data.

[0022] Based on the above solution, by coordinating the adjustment of the angle of the reflector and the illumination direction of the lighting module, the lighting effect can be further guaranteed.

[0023] In some possible implementations, the dishwasher door is equipped with a second angular displacement sensor for detecting the opening and closing angle of the door. Controlling the tumbler assembly in the dishwasher to rotate the reflector to a preset angle includes: Obtain the current rotation speed and current opening / closing angle of the door. When the current opening angle is greater than the preset angle, the flipping component is controlled to rotate the reflective element to the preset angle at a target rotation speed, where the target rotation speed is greater than the current rotation speed.

[0024] Based on the above scheme, after the door is opened to a preset angle, the flipping component is controlled to quickly rotate the reflective element, so that the reflective element can reach the target angle synchronously when the door is fully opened.

[0025] It should be understood that the above general description and the following detailed description are exemplary and explanatory only, and are not intended to limit this disclosure.

[0036] A dishwasher is a device that automatically cleans tableware such as bowls, chopsticks, plates, dishes, knives, and forks. It achieves cleaning by spraying water under high temperature and pressure to thoroughly rinse the surface of the tableware, greatly improving efficiency. The high temperature environment effectively kills bacteria, ensuring the tableware is clean and hygienic.

[0037] Currently, most dishwashers lack internal lighting or have only low-wattage lights, resulting in poor illumination inside the dishwasher, making it inconvenient for users to handle dishes and leading to a poor user experience. While some technologies incorporate multiple lights inside the dishwasher to improve brightness and coverage, this also increases the design and manufacturing costs.

[0038] To address at least one of the aforementioned technical problems, this disclosure provides an embodiment of a dishwasher, please refer to... Figure 1-3 The dishwasher includes a housing 1 and a door 2. The housing 1 has a cleaning chamber inside. The door 2 is rotatably connected to the housing 1. A reflective element 3 is rotatably installed on the side of the door 2 near the housing 1. The reflective element 3 is used to reflect external light sources into the cleaning chamber.

[0039] In this embodiment, the dishwasher is a side-opening dishwasher, meaning the door 2 is rotatably mounted on the side of the housing 1, and the rotation axis of the door 2 is located at the bottom of the side of the housing 1. The door 2 opens in a pull-down manner. In actual use, after opening the dishwasher door 2, the door 2 is close to a horizontal plane. By rotating the reflector element 3, the incident angle of the external light source is adjusted so that the emitted light is directed towards the dishwasher's cleaning chamber. In this way, the dishwasher's cleaning chamber can be illuminated by an external power source, thereby improving the lighting effect without adding additional lighting inside the cleaning chamber, and controlling the manufacturing cost of the dishwasher.

[0040] In some embodiments, no lighting components are installed in the washing chamber of the dishwasher; the dishwasher provides illumination within the washing chamber solely through reflective elements 3.

[0041] In some embodiments, the dishwasher's reflective element 3 has an automatic tumbling function. For details, please refer to... Figure 3 A flip assembly 4 is provided on the side of the door 2 near the housing 1. The flip assembly 4 is rotatably connected to a reflective element 3. The flip assembly 4 is used to rotate the reflective element 3 when the door 2 is in the open state so that the reflective element 3 reflects the light from the external light source into the cleaning chamber. A control module is provided in the dishwasher. The control module is located in the housing 1. The control module includes a controller. The controller is connected to the flip assembly 4. The controller is used to send a control signal to the flip assembly 4 so that the flip assembly 4 rotates a certain angle relative to the reflective element 3. The controller is also connected to the door 2 switch to obtain the door opening signal.

[0042] Based on the above structure, after the user opens the dishwasher door 2, the controller detects the door opening signal and sends a rotation control command to the flip assembly 4. The flip assembly 4 automatically rotates the reflector 3 to a target angle.

[0043] In this embodiment, the control module / controller can be integrated into the main control box of the dishwasher, or it can be a separate module component.

[0044] In a further embodiment, the flipping assembly 4 includes a drive motor located near the upper frame of the door 2. The output shaft of the drive motor is connected to a rotating shaft. The reflective element 3 has a mounting hole that is interference-fitted with the rotating shaft. When the door 2 is closed, the reflective element 3 is not flipped open, and the side of the reflective element 3 away from the mounting hole is close to the lower frame of the door 2. When the door 2 is fully open, the door 2 is nearly or horizontal, and the flipping assembly 4 rotates the reflective element 3 so that the side of the reflective element 3 away from the mounting hole gradually moves away from the lower frame of the door 2.

[0045] In this embodiment, the drive motor can be a stepper motor, and the controller can send a periodic signal to the stepper motor to adjust the number of steps of the stepper motor, thereby precisely adjusting the rotation angle of the reflector 3.

[0046] In a further embodiment, the flipping assembly 4 also includes a first angular displacement sensor, which is connected to the controller. The first angular displacement sensor is used to detect the angle between the reflective element 3 and the plane of the door 2 near the housing 1. This embodiment does not limit the specific selection of the first angular displacement sensor, nor does it limit the detection principle of the first angular displacement sensor. For example, the first angular displacement sensor can be a mechanical sensor, a resistive sensor, a capacitive sensor, or a photoelectric sensor, etc. In a preferred embodiment, the first angular displacement sensor can be an encoder based on photoelectric or magnetic fields.

[0047] In this embodiment, the flipping component 4 includes a drive motor and a first angular displacement sensor. The first angular displacement sensor can detect the flipping angle of the reflective element 3, enabling the dishwasher to determine the angle with the greatest light intensity and improve control precision.

[0048] In this embodiment, the external light source can be a lighting device in the kitchen space, or an appliance with a lighting module, such as a range hood, oven, or integrated stove. When the dishwasher door 2 is opened and the reflector 3 is rotated to the corresponding angle, at least part of the light from the external light source shines on the reflector 3, and the reflector 3 reflects the light into the washing chamber.

[0049] In some embodiments, the dishwasher can communicate with an external light source to enable the external light source to be turned on. Specifically, the control module also includes a communicator, and the controller in the control module is also connected to the communicator. The communicator is used for wireless communication with the external light source. The communicator can be a Wi-Fi module, Bluetooth module, or LoRa module, etc. Based on the communicator, after the dishwasher door 2 is opened, the communicator establishes a communication connection with the external light source to confirm the status of the external light source, and controls the external light source to turn on when it is detected that it is not lit, thereby ensuring the lighting effect.

[0050] In some embodiments, please refer to Figure 1-2 A light intensity detection module 5 is installed inside the cleaning chamber. The light intensity detection module 5 is connected to the controller and is used to detect the light intensity inside the cleaning chamber. This embodiment does not limit the specific selection of the light intensity detection module 5, nor does it limit the number of light intensity detection modules 5. For example, in some cases, there are two light intensity detection modules 5, which are located on opposite sides of the rear inner wall of the cleaning chamber. This arrangement can prevent inaccurate detection caused by tableware blocking one side of the light intensity detection module 5. In other cases, there are five light intensity detection modules 5, which are located on five inner surfaces of the cleaning chamber.

[0051] In this embodiment, based on the light intensity detection module 5, the dishwasher can be set with multiple lighting control modes to cope with different usage scenarios.

[0052] In one specific implementation, after the dishwasher door 2 is opened, the light intensity detection module 5 detects the light intensity inside the cleaning chamber. When the light intensity is greater than or equal to a threshold intensity, it is determined that the cleaning chamber is relatively bright, and the controller will not control the flipping assembly 4 to rotate the reflector element 3. Conversely, when the light intensity is less than the threshold intensity, it is determined that the cleaning chamber is relatively dark, and the controller controls the flipping assembly 4 to rotate the reflector element 3 and controls the external light source to illuminate. Therefore, adaptive lighting control can be achieved based on the light intensity detection module 5, which helps to save energy.

[0053] In another specific implementation, the light intensity detection module 5 serves to provide feedback on the light intensity to adjust the angle of the reflector element 3. Upon initial use of the dishwasher or after a change in the external light source, the controller first controls the flipping assembly 4 to rotate the reflector element 3 to an initial angle. Then, it controls the reflector element 3 to rotate within an angular range. The light intensity detection module 5 detects the light intensity within the cleaning chamber in real time and determines the angle corresponding to the maximum light intensity, thereby calibrating the optimal lighting angle, improving the brightness and coverage within the cleaning chamber, and enhancing the lighting effect.

[0054] In some embodiments, a second angular displacement sensor is also provided on the side of the door 2 near the housing 1. The second angular displacement sensor is connected to the controller and is used to detect the opening and closing angle of the door 2. The purpose of setting the second angular displacement sensor in this embodiment is to detect the opening and closing angle of the door 2 in real time so that the controller can control the flipping of the reflective element 3 in a staggered manner. Specifically, the second angular displacement sensor of the door 2 can accurately obtain the opening and closing angle of the door 2 and feed it back to the controller. The controller can control the rotation speed and angle of the reflective element 3 according to the opening and closing angle of the door 2 to avoid the reflective element 3 colliding with the housing 1 and being damaged. For example, when the door 2 rotates 60°, the rotation trajectory of the reflective element 3 will not collide with the housing 1. The controller controls the flipping assembly 4 to rotate the reflective element 3 at a rotation speed greater than that of the door 2, so that when the door 2 is fully opened, the reflective element 3 also opens to the correct position synchronously.

[0055] The above embodiments have described in detail a dishwasher disclosed herein, which uses a rotatable reflective element to illuminate the washing chamber with an external light source. Based on this setting, the lighting in the washing chamber can be eliminated, thereby reducing the cost of the dishwasher while ensuring the lighting effect.

[0056] This disclosure also provides a smart home system, including a range hood and a dishwasher according to any of the above embodiments. The range hood is located above the dishwasher, and a lighting module is provided at the bottom of the range hood. The light from the lighting module is directed towards the dishwasher. A communication module is provided in the range hood, and the range hood is wirelessly connected to the dishwasher through the communication module.

[0057] Based on the above scheme, the range hood and dishwasher are connected in communication. The dishwasher can send a signal to the range hood to turn on the lighting module, thereby realizing linkage lighting control.

[0058] In some embodiments, the illumination direction of the lighting module is adjustable. This adjustment ensures that the range hood lighting and dishwasher lighting do not conflict. Specifically, after the dishwasher door is opened, the dishwasher establishes a communication connection with the range hood and obtains the range hood's operating status. If the range hood is running, most of the light from the range hood's lighting module is directed towards the cooktop, while a small portion is directed towards the dishwasher's reflector. If the range hood is not running, the dishwasher can control the range hood's lighting module to adjust the illumination direction, ensuring that most or all of the light from the range hood's lighting module is directed towards the dishwasher's reflector. Based on this scheme, when the range hood is working, the lighting module is biased towards the cooktop; when the range hood is not working, the lighting module is biased towards the dishwasher, improving flexibility.

[0059] This disclosure also provides a lighting control method applied to a dishwasher in a smart home system described in the above embodiments. Please refer to... Figure 4 Lighting control methods include: Step S101: When the dishwasher door is detected to be open, establish a communication connection with the range hood in the smart home system.

[0060] Step S102: If the lighting module of the range hood is not lit, control the lighting module to turn on.

[0061] Step S103: Control the tumbling assembly in the dishwasher to rotate the reflector to a preset angle.

[0062] In one specific implementation, when the dishwasher door is unlocked, the dishwasher control module detects the door opening signal. Subsequently, the control module establishes a wireless communication connection with the range hood through a communicator and obtains the status of the range hood's lighting module. If the lighting module is not lit, the control module is turned on, and the flip assembly is controlled to rotate the reflector to a preset angle.

[0063] Based on the above solution, the dishwasher automatically connects to the range hood and controls the lighting module to turn on after the door is opened, and then controls the reflector to turn on, thereby completing the lighting of the dishwasher's cleaning chamber.

[0064] In some embodiments, a light intensity detection module is installed inside the washing chamber of the dishwasher to detect the light intensity within the washing chamber. The flipping assembly includes a first angular displacement sensor to detect the angle of the reflective element. Based on the first angular displacement sensor and the light intensity detection module, precise angle adjustment of the reflective element can be achieved, thereby ensuring the lighting effect inside the washing chamber of the dishwasher. For details, please refer to... Figure 5 After the aforementioned control unit in the dishwasher rotates the reflector to a preset angle, the lighting method further includes: Step S104: Control the flipping component to rotate the reflective element step by step, and record the light intensity data. The light intensity data represents the light intensity in the cleaning cavity at each step angle of the reflective element. Step S105: Based on the light intensity data, determine the target angle. The target angle represents the angle of the reflective element when the light intensity in the cleaning chamber is at its maximum. Step S106: Control the flipping assembly to rotate the reflective element to the target angle.

[0065] Based on the above scheme, by controlling the step rotation of the reflective element, the light intensity and angle can be associated and stored, which makes it easier to accurately determine the target angle corresponding to the maximum light intensity.

[0066] In some embodiments, the illumination direction of the lighting module is adjustable. The step of controlling the flip component to rotate the reflective element and recording the light intensity data in step S104 specifically includes: controlling the flip component to rotate the reflective element step by step, and controlling the lighting module to adjust the illumination direction and record the light intensity data during the time interval between two step rotations of the reflective element.

[0067] Based on the above solution, by coordinating the adjustment of the angle of the reflector and the illumination direction of the lighting module, the lighting effect can be further guaranteed.

[0068] In one specific implementation, when the dishwasher door is unlocked, the dishwasher's control module detects the door opening signal. The control module then establishes a wireless communication connection with the range hood via a communicator and obtains the range hood's operating status. When the range hood is in smoke extraction mode or the fan is running, the illumination direction of the range hood's lighting module is not adjusted; only the rotation angle of the reflector is adjusted until the light intensity inside the cleaning chamber reaches its maximum. The angle of the reflector at maximum light intensity is recorded as the first preset angle. When the range hood is not in smoke extraction mode or the fan is not running, the illumination direction of the range hood's lighting module and the rotation angle of the reflector are adjusted respectively until the light intensity inside the cleaning chamber reaches its maximum. The angle of the reflector at maximum light intensity is recorded as the second preset angle. In subsequent use, the reflector is controlled to rotate to either the first or second preset angle based on the range hood's operating status, and then the angle is fine-tuned.

[0069] In some embodiments, the dishwasher door is equipped with a second angular displacement sensor, which is used to detect the opening and closing angle of the door. Based on the second angular displacement sensor, the rotation of the reflective element can be synchronized with the opening and closing of the door, so that the cleaning chamber can be illuminated immediately. Specifically, the step S103 above, which controls the tumbling assembly in the dishwasher to rotate the reflective element to a preset angle, includes: S1031. Obtain the current rotation speed and current opening / closing angle of the door; S1032. When the current opening angle is greater than the preset angle, control the flipping component to rotate the reflective element to the preset angle according to the target rotation speed, where the target rotation speed is greater than the current rotation speed.

[0070] Based on the above scheme, after the door is opened to a preset angle, the flipping component is controlled to quickly rotate the reflective element, so that the reflective element can reach the target angle synchronously when the door is fully opened.

[0071] The various embodiments of this disclosure have been described above. These descriptions are exemplary and not exhaustive, nor are they limited to the disclosed embodiments. Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments. The terminology used herein is chosen to best explain the principles, practical application, or technical improvements to the embodiments in the market, or to enable others skilled in the art to understand the embodiments disclosed herein.
