[0039] A dishwasher is a household kitchen appliance designed to automatically clean dishes, utensils, and other kitchenware. It uses hot water and detergent to remove food residue and stains, and usually includes functions such as rinsing, washing, rinsing, and drying. Its working principle: pre-rinse stage: before formal washing, the dishwasher will perform a short pre-rinse to remove most of the food residue; detail stage: hot water mixed with detergent is pumped into the spray arm and sprayed out at high speed through the holes on the rotating spray arm, providing powerful cleaning for the dishes; rinsing stage: after washing, there is one or more rinsing cycles to remove residual detergent and loose dirt with clean hot water; drying stage: the dishwasher uses heating elements or residual heat to speed up the drying process of the dishes.
[0040] According to different designs and functions, dishwashers can be divided into various types, including built-in dishwashers, table-top dishwashers, sink-type dishwashers, drawer-type dishwashers, etc. The present application does not limit the type of the above-mentioned dishwashers.
[0041] The door lock state detection of the dishwasher is generally achieved by using traditional mechanical switches or magnetic induction switches, which need to be in contact with the door lock of the dishwasher. However, after long-term use and wear, the mechanical switches or magnetic induction switches may fail or fail, which will affect the judgment of the dishwasher control module and cause the dishwasher to malfunction. Therefore, the present application designs a non-contact photoelectric door lock state detection device to avoid direct contact with the door lock of the dishwasher, improving the reliability and stability of the dishwasher door lock detection.
[0042] Figure 1 is a structural diagram of a photoelectric door lock state detection device according to an exemplary embodiment. As shown in Figure 1 The photoelectric door lock state detection device can include an elastic member 6, a photoelectric component 8, and a pull cord 3.
[0043] The pull cord 3 is the connecting component for opening and closing the dishwasher door 1. One end of the pull cord 3 is connected to the dishwasher door 1, and the other end is connected to the elastic element 6. The pull cord 3 is a rope without elastic deformation, meaning that the pull cord 3 will not stretch or shorten under stress. The door 1 is used to seal the dishwasher's washing chamber to prevent water from splashing out during washing and causing safety issues.
[0044] One end of the elastic element 6 is connected to the pull cord 3, and the other end is fixed to the bottom of the dishwasher. When the user applies external force to open or close the door 1, the pull cord 3 pulls the elastic element 6 to extend and retract. The elastic element 6 can be a coil spring, torsion spring, etc., all of which are made of metal and have high strength and good elastic recovery capability. This invention does not limit the type of elastic element 6.
[0045] The optoelectronic component 8 includes a photoelectric transmitter 4 and a photoelectric receiver 5. For example... Figure 2 As shown, the photoelectric transmitter 4 is located on one side of the moving trajectory of the pull rope 3, and the photoelectric receiver 5 is located on the other side of the moving trajectory of the pull rope 3. The photoelectric transmitter 4 and the photoelectric receiver 5 can be arranged opposite each other or in a cross arrangement. For example, the photoelectric transmitter 4 is located above the connection between the pull rope 3 and the elastic member 6, or below the connection between the pull rope 3 and the elastic member 6, or the photoelectric transmitter 4 is located below the pull rope 3, and the photoelectric receiver 5 is located above the pull rope 3. This invention does not limit the specific position of the photoelectric component 8. Preferably, both the photoelectric transmitter 4 and the photoelectric receiver 5 are located at the connection between the pull rope 3 and the elastic member 6, and the photoelectric transmitter 4 and the photoelectric receiver 5 are arranged opposite each other, that is, the emission path of the light source from the photoelectric transmitter 4 to the photoelectric receiver 5 is perpendicular to the moving trajectory of the pull rope 3. Setting up photoelectric component 8 avoids direct contact with other components on the dishwasher, such as mechanical switches. For example, a mechanical switch on a door lock would need to directly contact the lock when the door is opened or closed to determine its status. Using a non-contact photoelectric door lock status detection device increases the dishwasher's detection capabilities and extends the lifespan of the door lock mechanism. Conversely, a door lock switch on a door lock would need to directly contact the lock when the door is opened or closed.
[0046] The photoelectric emitter 4 is responsible for emitting a light source, such as infrared light, laser light, or visible light. This invention does not limit the type of light source. The photoelectric emitter 4 can be a light-emitting diode (LED) or a laser, capable of continuously emitting a light beam to the photoelectric receiver 5. This invention does not limit the type of the photoelectric emitter 4.
[0047] The photoelectric receiving end 5 corresponds to the photoelectric emitting end 4. The photoelectric receiving end 5 can be provided as a photosensitive sensor, and the type of the photoelectric receiving end 5 is not limited in the utility model. The photoelectric receiving end 5 is used for receiving the light intensity of the light source irradiating the pull rope 3 or the light intensity of the light source irradiating the elastic member 6 from the photoelectric emitting end 4, and transmitting the corresponding light intensity information to the control module. Exemplarily, the photoelectric emitting end 4 irradiates on the pull rope 3, and the pull rope 3 will block most of the light source, so that the photoelectric receiving end 5 can only receive a small part of the light source, and then the light intensity is low, that is, indicating that the door body 1 of the dishwasher is in a closed state. In the case that the door body 1 is opened, the light source will irradiate on the elastic member 6, that is, in the case that the door is opened, the elastic member 6 will be elongated, thereby generating deformation. The light source will be reflected to the photoelectric receiving end 5 through the gap of the deformation of the elastic member 6, and then the light intensity of the elastic member 6 received by the photoelectric receiving end 5 will be greater than the light intensity of the pull rope 3.
[0048] The photoelectric door lock state detection device further comprises a control module, the control module is the brain of the dishwasher, and is responsible for executing the monitoring and instruction operation in the dishwasher. The control module is connected with the photoelectric component 8, the control module and the photoelectric emitting end 4 are connected, and the control module is used for controlling the photoelectric emitting end 4 to continuously emit the light source. The control module is connected with the photoelectric receiving end 5, and is used for receiving the light intensity information of the photoelectric receiving end 5 and judging the light intensity information. In the case that the light intensity information is the light intensity of the light source irradiating on the elastic member 6, it is determined that the door body 1 of the dishwasher is in an opened state. In the case that the light intensity information is the light intensity of the light source irradiating on the pull rope 3, it is determined that the door body 1 of the dishwasher is in a closed state. Exemplarily, a preset light intensity value is arranged in the control module. In the case that the light intensity value in the obtained light intensity information is greater than the preset light intensity value, that is, the light intensity of the light source irradiating on the elastic member 6, it is indicated that the door body 1 of the dishwasher is in an opened state. In the case that the light intensity value in the obtained light intensity information is less than or equal to the preset light intensity value, that is, the light source irradiates on the pull rope 3, it is indicated that the door body 1 of the dishwasher is in a closed state.
[0049] Figure 3 is a schematic view of an elastic member according to an exemplary embodiment. As shown in Figure 3 The elastic member 6 is coated with different color pigment coatings, and the pigment coatings are distributed along the axial direction of the elastic member 6, for example, the length of the entire elastic member 6 can be 20 cm, and each two cm corresponds to a color, and from the end of the elastic member 6 connected with the pull rope 3, the colors can be red, blue, green, cyan, purple and the like, and the specific color distribution and the length corresponding to each color are not limited in the utility model.
[0050] When the door body 1 of the dishwasher is opened, the photoelectric emission end 4 emits light source to the pigment coating, and the pigment coating can reflect the light source of the photoelectric emission end 4 to the photoelectric receiving end 5. The photoelectric receiving end 5 receives the light signal reflected by the pigment coating and sends the corresponding light signal to the control module. Different colors of the pigment coating correspond to different light signals, for example, the red corresponding pigment coating mainly reflects red light, and the wavelength of the red corresponding light is relatively long; the blue corresponding pigment coating mainly reflects blue light, and the wavelength of the blue corresponding light is relatively short, and the utility model does not make limitation to this.
[0051] After the control module receives the light signal sent by the photoelectric receiving end 5, the corresponding light signal is analyzed immediately, and then the opening and closing angle of the door body 1 is determined. The light signal of each pigment coating corresponds to the opening and closing angle of the door body 1. Exemplarily, when the photoelectric receiving end 5 receives the red light signal, the control module can determine that the opening and closing angle of the door body 1 may be between 10° and 20°, that is, the door body 1 of the dishwasher is just in the opening stage; when the photoelectric receiving end 5 receives the purple corresponding light signal, the control module can determine that the opening and closing angle of the door body 1 can be between 80° and 90°, that is, the door body 1 is completely opened. The utility model does not make limitation to the corresponding relationship between the light signal and the opening and closing angle of the door body 1.
[0052] In a possible implementation, the dishwasher further comprises an illuminating lamp, wherein the illuminating lamp is installed in the inner cavity of the dishwasher, and the illuminating lamp is connected with the control module of the photoelectric door lock state detection device. The illuminating lamp can be a LED lamp, and the utility model does not make limitation to this. The illuminating lamp illuminates the inside of the washing cavity of the dishwasher when the door body 1 of the dishwasher is in the opened state. The illuminating lamp is a breathable illuminating lamp, that is, the brightness of the illuminating lamp can dynamically change. For example, the brightness of the illuminating lamp changes from bright to dark in the case of opening the door body 1 to closing the door body 1, and the brightness of the illuminating lamp changes from dark to bright in the case of closing the door body 1 to opening the door body 1.
[0053] The control module obtains the opening and closing angle of the door body 1 from the light signal, and then can control the illumination brightness of the illuminating lamp of the dishwasher. Exemplarily, the brightness level of the illuminating lamp can be divided into multiple levels, such as the lowest level, the second level, the third level, the highest level, and the like, and the present application does not limit this. When the opening and closing angle of the door body 1 is 10 degrees, that is, in the stage of just opening the door body 1, the control module controls the illuminating lamp to adjust the illuminating lamp to the lowest level of the brightness level. When the opening and closing angle of the door body 1 is between 80° and 90°, the control module can adjust the illuminating lamp to the highest level of the brightness level, and the present application does not limit the corresponding relationship between the opening and closing angle and the brightness of the illuminating lamp. The breathable illuminating lamp is arranged in the dishwasher and connected with the control module, and the brightness of the illuminating lamp is adjusted by the control module, so that the dishwasher can ensure the lighting effect while saving energy and reducing power consumption.
[0054] In a possible implementation, the photoelectric door lock state detection device further comprises at least one roller 2, and the number of the roller 2 is not limited by the present application. The roller 2 is fixedly arranged between the door body 1 and the elastic member 6, and the pull rope 3 is in contact with the roller 2, that is, the door body 1 drives the pull rope 3 to move when the door body 1 is opened or closed, and then the pull rope 3 drives the roller 2 to roll. The arrangement of the roller 2 in the photoelectric door lock state detection device can reduce friction and wear, and prolong the service life of the pull rope 3 and the entire photoelectric door lock state detection device.
[0055] In a possible implementation, the photoelectric door lock state detection device can further be provided with a baffle, which can be installed on the outside of the photoelectric door lock state detection device of the dishwasher. The baffle can shield factors that can damage the photoelectric component 8 outside the dishwasher, such as splashing water droplets, external light sources, dust, and the like, and the present application does not limit this. This can help to protect the cleanliness of the photoelectric door lock state detection device, avoid external interference to the photoelectric component 8, and improve the accuracy of photoelectric door lock state detection; at the same time, it can also avoid safety problems such as electric shock.
[0056] In a possible implementation, the photoelectric door lock detection device further comprises an angle detection sensor, which can be arranged on one side of the door body 1. The angle detection sensor is connected with the control module. The angle detection sensor can be a Hall effect angle sensor, which utilizes the Hall effect to perceive the angle change. A Hall semiconductor sheet is placed in a magnetic field, and a constant current is applied to the Hall semiconductor sheet. The change of the magnetic field is converted into the change of the voltage of the semiconductor sheet. The change of the voltage is monitored to measure the rotation angle of the object. The angle detection sensor can also be a magnetoresistance effect angle sensor. When a magnetic field is applied to a metal or semiconductor with a current, the resistance value of the metal or semiconductor will change obviously, which is called magnetoresistance effect. The angle sensor made by utilizing this principle is a magnetoresistance effect angle sensor. The type of the angle detection sensor is not limited in the utility model.
[0057] When the control module detects that the photoelectric component 8 fails, for example, the light source of the photoelectric emission end 4 cannot emit light, or the photoelectric receiving end 5 detects a deviation. The utility model does not limit the specific fault type. At this time, the control module immediately stops the operation of the photoelectric component 8 and starts the standby angle detection device, that is, sends a monitoring instruction to the angle detection sensor. After the angle detection sensor receives the monitoring instruction, it immediately enters the working state, monitors the opening and closing angle of the door body 1 in real time, and simultaneously sends the opening and closing angle of the door body 1 to the control module in real time. The angle detection sensor can further improve the reliability and stability of the door lock state detection of the dishwasher and provide the user with a safer and more convenient door lock use experience.
[0058] In a possible implementation, the photoelectric door lock state detection device further comprises a display unit 7; the display unit 7 is connected with the control module, the display unit 7 can display the control instruction corresponding to the control module, and simultaneously display the fault information corresponding to the photoelectric component 8 in the case that the photoelectric component 8 fails, and directly and clearly report the fault information to the user. The display unit 7 can also display the solution corresponding to the fault information, help the user quickly locate the problem and take corresponding solving measures, and improve the use experience of the user.
