Description

Technical Field

[0001] This utility model relates to the field of dishwasher technology, and in particular to a lighting control device for a dishwasher and a dishwasher. Background Technology

[0002] Dishwashers in the kitchen typically have internal lighting to illuminate the interior. This lighting is only needed when interaction with the dishwasher's interior is required; therefore, it is often used in conjunction with door lock detection functionality.

[0003] In existing technology, the dishwasher door latch is located on the door. When the door is closed, the latch blocks a microswitch, activating the circuit. The dishwasher's main control processor (MCU) detects this circuit continuity to determine if the door is open. If the door is detected as open, the MCU controls the lighting to turn on, allowing the user to see the interior of the dishwasher. However, after prolonged use, the microswitch is prone to mechanical wear, insufficient lubrication, and spring fatigue, causing it to malfunction and fail to detect the door lock. Furthermore, if foreign objects become lodged in the microswitch, it may remain in a continuously connected state, leading to abnormal door lock detection. Therefore, there is an urgent need for a dishwasher lighting control device with strong door switch detection capabilities to address these issues. Utility Model Content

Detailed Implementation

[0038] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0039] Washing appliances (such as dishwashers) all have door lock detection. The door lock latch is located on the door. When the door is closed, the latch will block the micro switch, making the circuit conductive, and the main control MCU (Microcontroller Unit) will detect and judge.

[0040] This conventional door switch detection method can easily detect door switch signals. However, long-term use of microswitches may lead to mechanical wear, insufficient lubrication, spring fatigue, and other problems, causing the microswitches to fail to perform the function of door switch detection. It is also possible that foreign objects may get stuck in the microswitches, causing them to remain connected and resulting in abnormal dishwasher door lock detection.

[0041] Washing appliances typically have internal lighting for illumination. However, these lights are usually constant and do not work in conjunction with other components, making their design too simplistic.

[0042] like Figure 1 As shown in the figure, this utility model discloses a lighting control device for a dishwasher. By incorporating a door moving assembly, a control device, and a door angle detection device, the device detects the open / closed state of the door and further controls the lighting device based on this state. By improving the ability to detect the door's open / closed state during dishwasher use, the lighting control effect is improved, solving the efficiency problem of lighting control during dishwasher operation. The lighting control device includes a door moving assembly 1, a control device 2, and a door angle detection device 3. The door moving assembly 1 is disposed within the dishwasher's outer casing 4 and fixedly connected to the dishwasher's door 5. The control device 2 is disposed within the dishwasher's outer casing, and the door angle detection device 3 is disposed on the dishwasher's door 5.

[0043] The door moving assembly 1 includes a connecting device 6 and an elastic device 7. The connecting device 6 is fixedly connected to the elastic device 7. The connecting device 6 is fixedly connected to the door 5 of the dishwasher and the outer shell 4 of the dishwasher, respectively.

[0048] Optionally, such as Figure 1As shown, the control device 2 includes a sensing device 8 and a lighting device 9. The sensing device 8 senses the extension and retraction of the elastic device 7, thereby detecting the opening and closing state of the door 5. The lighting device 9 illuminates the interior of the dishwasher cavity. The sensing device 8 is electrically connected to the lighting device 9 so that the lighting device 9 illuminates according to the detection result of the sensing device 8. Specifically, when the sensing device 8 detects that the door 5 is open, it controls the lighting device 9 to start the lighting; when the sensing device 8 detects that the door 5 is closed, it controls the lighting device 9 to turn off the lighting.

[0049] Optionally, such as Figure 1 As shown, the door angle detection device 3 is installed on the door 5 of the dishwasher and is used to detect the opening and closing angle of the door 5. Specifically, when the door 5 is closed, it is in the closed position. When the door 5 is open, the angle between the current position of the door 5 and the closed position is the opening and closing angle of the door 5.

[0050] Optionally, such as Figure 1 As shown, the door angle detection device 3 is electrically connected to the control device 2. The door angle detection device 3 transmits the detected opening and closing angle of the dishwasher door 5 to the control device 2 so that the control device 2 controls the brightness of the lighting device 9 according to the size of the opening and closing angle.

[0051] Optionally, when the opening angle is less than a preset angle, the lighting device 9 is controlled to illuminate at a first brightness; when the opening angle is greater than the preset angle, the lighting device 9 is controlled to illuminate at a second brightness, wherein the first brightness is less than the second brightness. The control device 2 can also control the lighting device 9 to illuminate by sequentially increasing the lighting brightness according to the opening angle from small to large.

[0052] Optionally, such as Figure 2 As shown, the connecting device 6 includes a pull cord 10 and a roller 11, with the roller 11 positioned at a preset roller position within the dishwasher housing 4.

[0053] The pull rope 10 is slidably connected to the roller 11;

[0055] Optionally, such as Figure 3 As shown, the pull rope 10 includes a first end 14 and a second end 15.

[0056] The first end 14 is fixedly connected to the door 5 of the dishwasher;

[0057] The second end 15 is fixedly connected to the elastic device 7.

[0058] Optionally, such as Figure 2 As shown, the pull rope 10 is used to connect the door body 5 and the elastic device 7 to maintain the opening force and rebound force on the door body 5.

[0059] Optionally, such as Figure 2 As shown, the roller 11 is used to control the direction of movement of the pull rope 10 so that the pull rope 10 can provide opening force and rebound force to the door body 5.

[0060] Optionally, such as Figure 3 As shown, the pull cord 10 includes a first end 14 and a second end 15. The first end 14 is fixedly connected to the door 5 of the dishwasher, and the second end 15 is fixedly connected to the elastic device 7. When the door 5 is opened, the pull cord 10 moves toward the door 5; when the door 5 is closed, the pull cord 10 moves toward the elastic device 7.

[0061] In this embodiment, the opening force and rebound force of the door are maintained by the pull rope and roller, eliminating the need for the user to bear the weight of the door, thus improving the user experience. It also facilitates the subsequent deformation of the elastic device based on the pull rope, thereby determining the opening and closing state of the door based on the deformation of the elastic device, which improves the accuracy of the detection of the opening and closing state of the door.

[0062] Optionally, such as Figure 4 As shown, the preset roller positions include a first roller preset position and a second roller preset position, and the roller 11 includes a first roller 12 and a second roller 13.

[0063] The first roller 12 is disposed at a preset position, and the second roller 13 is disposed at a preset position.

[0064] The pull rope 10 is slidably connected to the first roller 12 and the second roller 13 respectively.

[0065] Optionally, such as Figure 4 As shown, the roller 11 includes a first roller 12 and a second roller 13. The pull rope 10 passes through the first roller 12 and the second roller 13 and is disposed inside the housing 4, thereby reducing the size of the connecting device 6.

[0066] Optionally, such as Figure 4 As shown, the pull rope 10 is parallel to the bottom of the housing 4 via the first roller 12 and the second roller 13.

[0067] In this embodiment, the direction of the pull rope is changed based on the first roller and the second roller, which reduces the size of the connecting device 6 and makes the structure simple and easy to install.

[0068] Optionally, such as Figure 5 As shown, the control device 7 also includes a control unit 16.

[0069] The control unit 16 is electrically connected to the sensing device 8, the lighting device 9, and the door angle detection device 3, respectively.

[0070] Optionally, the sensing device 8 includes a sensing signal output port, and the control unit includes a sensing signal input port.

[0071] The induction signal output port is electrically connected to the induction signal input port.

[0072] Optionally, the control unit 16 further includes a control signal output port, and the lighting device 9 includes a control signal input port.

[0073] The control signal output port is electrically connected to the control signal input port.

[0074] Optionally, the control unit 16 is integrated into the power board of the dishwasher.

[0075] Optionally, such as Figure 5 As shown, the control device 7 further includes a control unit 16, which is electrically connected to the sensing signal output port via the sensing signal input port. The control unit 16 is also electrically connected to the sensing device 8. The sensing device 8 outputs the sensing result of the opening and closing state of the door 5 via the sensing signal output port. The control unit 16 receives the sensing result output by the sensing device 8 via the sensing signal input port, and controls the lighting device 9 accordingly based on the sensing result.

[0076] Optionally, such as Figure 5 As shown, the control unit 16 further includes a control signal output port. The control unit 16 is electrically connected to the lighting device 9 through the control signal output port. The control unit 16 outputs a lighting control signal through the control signal output port, and the lighting device 9 receives the lighting control signal through the control signal input port and performs lighting based on the lighting control signal. Specifically, the lighting control signal includes a start signal and a brightness signal. The start signal indicates whether the lighting is turned on or off, and the brightness signal indicates the brightness of the lighting.

[0077] Optionally, the lighting device is a lamp and a driving unit, wherein the driving unit can drive the lamp to turn on and off, and can also drive the lamp to emit different brightness levels.

[0078] Optionally, the control unit 16 is integrated into the power board of the dishwasher, which improves the integration of the dishwasher.

[0079] In this embodiment, the door opening and closing status is detected by a sensing device to obtain the door opening and closing status detection result. The door opening and closing angle information is obtained by a door angle detection device. The control unit analyzes the door opening and closing status detection result and the door opening and closing angle information to obtain lighting control information. The lighting device is controlled to provide lighting based on the lighting control information. This avoids detection errors caused by microswitch failure, improves the linkage between the lighting device and other components, and enhances the user experience.

[0080] Optionally, the elastic device 7 is made of spring steel, and the sensing device 8 is a Hall sensor.

[0081] The Hall sensor is used to detect the change in the magnetic field of the spring steel.

[0082] Optionally, the sensing device 8 is a Hall sensor. A Hall sensor is a magnetic field sensor based on the Hall effect. A Hall sensor can convert a changing magnetic field into a change in output voltage for measuring the magnetic field.

[0083] Optionally, the elastic device 7 is spring steel, and the elastic device 7 is spring steel in the shape of a spring.

[0084] Optionally, under the action of the pull rope 10, the amount of extension and retraction of the spring steel changes, resulting in a change in the magnetic field. The change in the magnetic field of the spring steel is detected by a Hall sensor, and the opening and closing state of the door 5 is confirmed based on the change in the magnetic field.

[0085] Optionally, during the opening of the door 5, the pull rope 10 moves toward the door 5. Since the length of the pull rope 10 does not change, the movement of the pull rope 10 will cause the spring steel to stretch, generating a rebound force. During the closing of the door 5, the pull rope 10 moves toward the spring steel, and the spring steel contracts until the door 5 is completely closed, at which point the spring steel contracts to its natural state.

[0086] Optionally, during the opening and closing of the door 5, the spring steel is stretched or contracted according to the opening and closing angle of the door 5. Since spring steel is a magnetic material, its internal magnetic field changes during the stretching and contraction process, and the spring steel can be used as a trigger source for a magnetic switch or a Hall sensor.

[0087] Optionally, a Hall sensor is installed near the spring steel of the dishwasher to detect the change in the magnetic field caused by the stretching or contraction of the spring steel, thereby determining the door opening angle. The door opening angle can then be used to simultaneously determine whether the door is fully closed. The spring steel is within the detection range of the Hall sensor.

[0088] In this embodiment, the use of spring steel and Hall effect sensors improves the accuracy of detecting the opening and closing state of the door, thereby enhancing the control effect of the lighting.
