[0084] The embodiments provided in this application will now be described in detail with reference to the accompanying drawings.

[0085] Figure 10 This is a schematic diagram of the appearance of a dishwasher provided in this embodiment. Figure 10 As shown, a is a schematic diagram of the dishwasher before washing dishes, b is a schematic diagram of the dishwasher during the washing process, and c is a schematic diagram of the dishwasher after washing dishes.

[0086] like Figure 10 As shown, the dishwasher 100 is equipped with a detergent inlet 101, through which users can add dish soap or dishwasher powder and other dishwashing detergents. A water tank inlet 102 is located on top of the dishwasher 100, through which users can add water to the water tank 19 for washing dishes 200. The water tank 19 may have a built-in water softener, so water softener salt can also be added through the water tank inlet 102. The dishwasher may include a sliding track and a chassis layer 103. The chassis layer 103 can pull the dishwasher 100 out of the sliding track or push the dishwasher 100 in. The chassis layer 103 may include a traction plate 135, a bubble plate 134, a support spring 133, a heating plate 132, and a partition 131, as shown. Figure 10 As shown in Figure a, before the dishwasher 100 washes the dishes 200, the base tray 103 can be pulled out, and the dishes 200 to be washed can be placed upside down on the base tray 103. Water is then added to the base tray 103 to submerge the dishes 200. Finally, the base tray 103 is pushed into the dishwasher 100. Figure 10 As shown in b, after confirming that the chassis layer 103 is closed, the dishwasher 100 can perform the washing and disinfection process of the tableware 200, as shown in the figure. Figure 10 As shown in c, after the washing and disinfection process of the tableware 200 is completed, the top cover 104 of the dishwasher 100 pops open, and the user can take out the washed and disinfected tableware 200.

[0087] In some embodiments, such as Figure 11 As shown, before the dishwasher 100 washes the dishes 200, the pull plate 135 can be pulled out separately and the dishes 200 to be washed can be placed upside down on the pull plate 135. Then the pull plate 135 is pushed into the dishwasher 100 so that the dishwasher 100 can perform the washing and disinfection process of the dishes 200.

[0088] Figure 12 This is a schematic diagram of the internal structure of the chassis layer of a dishwasher provided in this embodiment. In some embodiments, such as... Figure 12 As shown, the chassis layer may include a traction plate 135, a partition 131, a bubble plate 134, a heating plate 132, a temperature sensor 28, and a turbidity sensor 29, although Figure 12 Not shown, the chassis layer may also include a pressure sensor 16, a support spring 133, and a telescopic sleeve 15.

[0089] In some embodiments, the combination of partition 131, pressure sensor 16, support spring 133 and telescopic sleeve 15 can be referred to as a washing layer.

[0090] In some embodiments, the traction plate 135 may also be referred to as the traction layer, the bubble plate 134 may also be referred to as the steam bubble layer, the heating plate 132 may also be referred to as the heating layer, the support spring 133 may also be referred to as the support vibration spring, and the telescopic sleeve 15 may also be referred to as the thermal expansion sleeve. The description of the traction plate 135, the bubble plate 134, the heating plate 132, the support spring 133 and the telescopic sleeve 15 can be referred to the relevant description of the above embodiments, and will not be repeated here.

[0091] In some embodiments, pressure sensor 16 may be a pressure-sensitive sensor. It should be understood that a pressure sensor is a device or apparatus capable of sensing pressure signals and converting them into usable output electrical signals according to necessary rules. Typically, a pressure sensor consists of a pressure-sensitive element and a signal processing unit. Depending on the type of pressure being tested, pressure sensors may include gauge pressure sensors, differential pressure sensors, and absolute pressure sensors.

[0092] Figure 13 The following is a flowchart illustrating a dishwasher control method provided in an embodiment of this application. The method is applied to the dishwasher controller and includes the following steps:

[0093] S101, Obtain the pressure value.

[0094] In some embodiments, the pressure value of the support spring can be obtained before the dishwasher begins the washing and sanitizing process.

[0095] Understandably, when a user needs to use the dishwasher to wash dishes, they can control the dishwasher to turn on. For example, they can press the power button on the display panel to turn on the dishwasher, add water to the water tank through the water inlet to the preset water level, and add water softener salt. The preset water level can be predefined at the factory, for example, the preset water level can be 4000 ml. At the same time, pull out the base layer from the dishwasher body, place the dishes to be washed upside down on the base layer, add an appropriate amount of water to submerge the dishes, and then push the base layer into the dishwasher body. At this time, the pressure sensor obtains the pressure value carried by the support spring and sends it to the controller.

[0096] The tableware that needs to be cleaned may include chopsticks, spoons, rice bowls, side dishes, soup bowls, cups, or stainless steel basins.

[0097] In some embodiments, after the controller obtains the pressure value, it can control the dispenser to dispense dish soap or dishwasher powder.

[0098] S102. Start the corresponding washing mode according to the pressure value, and control the heating plate to work when the pressure value is greater than or equal to the pressure threshold.

[0099] In some embodiments, such as Figure 14 As shown, step S102 can be specifically implemented as follows:

[0100] S1021. Determine the type of tableware based on the pressure value.

[0101] In some embodiments, the pressure value corresponding to each type of tableware can be pre-stored in the dishwasher when it leaves the factory. Therefore, the type of tableware that needs to be washed can be determined based on the obtained pressure value.

[0102] As a possible example, if the pressure value is within a first preset pressure value range, the type of tableware is determined to be chopsticks or a spoon, wherein the first preset pressure value range is determined in advance through a large amount of data collection and is stored in the dishwasher in advance when the dishwasher leaves the factory. For example, the first preset pressure value range may be 5 to 20 grams.

[0103] As another possible example, when the pressure value is within the second preset pressure value range, the type of tableware is determined to be a rice bowl. The second preset pressure value range is determined in advance through a large amount of data collection and is stored in the dishwasher in advance when the dishwasher leaves the factory. The lower limit of the second preset pressure value range is above the upper limit of the first preset pressure value range. For example, the second preset pressure value range can be 50 to 200 grams.

[0104] As another possible example, when the pressure value is within the third preset pressure value range, the type of tableware is determined to be a plate. The third preset pressure value range is determined in advance through a large amount of data collection and is stored in the dishwasher in advance when the dishwasher leaves the factory. The lower limit of the third preset pressure value range is above the upper limit of the second preset pressure value range. For example, the third preset pressure value range can be 220 to 400 grams.

[0105] As another possible example, when the pressure value is within the fourth preset pressure value range, the type of tableware is determined to be a soup bowl. The fourth preset pressure value range is determined in advance through a large amount of data collection and is stored in the dishwasher in advance when the dishwasher leaves the factory. The lower limit of the fourth preset pressure value range is above the upper limit of the third preset pressure value range. For example, the fourth preset pressure value range can be 420 to 600 grams.

[0106] S1022. Start the corresponding washing mode according to the type of tableware.

[0107] In some embodiments, each type of tableware is provided with a corresponding washing mode, and the washing mode corresponding to each type of tableware is pre-stored in the dishwasher at the factory.

[0108] As a possible example, if the type of cutlery is determined to be chopsticks or a spoon, the first washing mode is initiated.

[0109] As another possible example, if the type of tableware is determined to be a rice bowl, the second washing mode is activated.

[0110] As another possible example, if the type of tableware is determined to be a plate, the third washing mode is activated.

[0111] As another possible example, if the type of tableware is determined to be a soup bowl, the fourth washing mode is activated.

[0112] The washing processes for the first, second, third, and fourth washing modes can be the same, but the washing times will differ. It should be understood that the surface area of ​​each type of tableware is different; the larger the surface area of ​​the tableware, the longer the washing time. A rice bowl has a larger surface area than chopsticks or spoons, a plate has a larger surface area than a rice bowl, and a soup bowl has a larger surface area than a plate. Therefore, the washing times for the first, second, third, and fourth washing modes can be predefined at the dishwasher's factory as follows: the first washing mode can be 240 seconds (s), the second washing mode can be 300 seconds, the third washing mode can be 400 seconds, and the fourth washing mode can be 500 seconds.

[0113] S1023. When the pressure value is greater than or equal to the pressure threshold, control the operation of the corresponding heating point.

[0114] Understandably, the heating points on the heating plate correspond one-to-one with the support springs. After the controller obtains the pressure value of the support springs, it controls the corresponding heating points to work when the pressure value is greater than or equal to the pressure threshold, so that the water in the chassis layer boils.

[0115] The pressure threshold can be predefined at the factory of the dishwasher; for example, the pressure threshold can be 50 Pa.

[0116] In some embodiments, the support spring oscillates under the action of boiling water, thereby shaking the tableware and removing dirt from the surface of the tableware, achieving a washing effect. The tableware can also be sterilized at high temperature in boiling water.

[0117] S103. Open the top cover and allow the air to dry.

[0118] In some embodiments, after the washing mode corresponding to the dishes to be washed is completed, the motor drives the traction plate to be fixed on the top of the dishwasher, the washed dishes are placed on the traction plate, the controller pops open the top cover to air dry the dishes, and the user can take the washed dishes from the top of the dishwasher.

[0119] based on Figure 13 The illustrated embodiment offers at least the following beneficial effects: This application provides a dishwasher with a simple mechanical structure, the core of which consists of a heating plate and a support spring, requiring only a small amount of water. The dishwasher utilizes the support spring to support the tableware. Boiling water can directly act on the tableware, causing it to shake. The boiling water also acts on the support spring, causing it to oscillate. The support spring vibrates axially, and its upper end sways back and forth and left and right, thus causing the tableware to shake, achieving the effect of washing and disinfecting the tableware. In this way, the dishwasher provided by this application embodiment can wash and disinfect tableware using a small amount of water, making it suitable for use while traveling and providing great convenience to users who need to use tableware while on the go.

[0120] The following example illustrates a dishwasher control method provided in this application. Figure 15 This application provides a flowchart illustrating a control method for a third washing mode of a dishwasher, specifically a control method for washing dishes. The method is applied to the dishwasher's controller, which is a computer board. Figure 15 As shown, the method includes the following steps:

[0121] S201, Control the dishwasher to start.

[0122] Understandably, when users need to use the dishwasher to wash dishes, they can control the dishwasher to turn it on. For example, they can press the power button on the display panel to turn on the dishwasher, add water to the water tank through the water inlet to the preset water level and add water softener salt, pull out the base from the dishwasher body, place the dishes to be washed upside down on the base, add an appropriate amount of water to submerge the dishes, and then push the base back into the dishwasher body.

[0123] The description of the preset water level can be found in the relevant description of step S101 above, and will not be repeated here.

[0124] S202, Obtain the pressure value.

[0125] With the chassis layer confirmed to be closed, obtain the pressure value, which is the pressure value borne by the support spring.

[0126] If the chassis layer is not closed within a first preset time, the voice prompt device can issue a first voice prompt to remind the user to close the chassis layer.

[0127] The first preset time can be predefined at the factory, for example, the first preset time can be 300 seconds. The content of the first voice prompt can also be predefined at the factory, for example, the content of the first voice prompt can be: "Please close the chassis layer in time".

[0128] S203. Determine the type of tableware based on the pressure value.

[0129] In some embodiments, the description of determining the type of tableware based on the pressure value can refer to the relevant description of step S1021 above, and will not be repeated here.

[0130] In this embodiment, the type of tableware is described as a plate.

[0131] S204. Start the corresponding washing mode according to the type of tableware.

[0132] In some embodiments, the description of activating the corresponding washing mode according to the type of tableware can be referred to the relevant description of step S1022 above, and will not be repeated here.

[0133] In this embodiment, the washing mode is described as the third washing mode.

[0134] S205. When the pressure value is greater than or equal to the pressure threshold, control the operation of the corresponding heating point.

[0135] In some embodiments, the description of controlling the operation of the corresponding heating point when the pressure value is greater than or equal to the pressure threshold can be referred to the relevant description of step S1023 above, and will not be repeated here.

[0136] It should be noted that if the pressure value is lower than the pressure threshold, it indicates that there is not enough water in the chassis layer, and water needs to be added to the chassis layer. Once it is determined that water needs to be added to the chassis layer, the water pump is controlled to operate in the first working state, and the first pipeline valve is opened, allowing water from the water tank to be pumped into the chassis layer.

[0137] The first working state can be either counterclockwise or clockwise.

[0138] In some embodiments, the pressure sensor monitors the pressure value in real time during the dishwashing process. When the pressure value is greater than or equal to the pressure threshold, the water pump is controlled to stop working, the first pipeline valve is controlled to close, and the corresponding heating point is controlled to work.

[0139] Understandably, as the water in the base layer is heated, its temperature gradually rises. When the temperature reaches the boiling point, the water boils. Under the action of the boiling water, the supporting spring vibrates axially, and the upper end wobbles back and forth and left and right, causing the dishes to shake. At the same time, since the dishes are placed upside down in the base, the bubbles generated by the heated water gather on the inside of the dishes and explode under pressure, causing dirt to be removed from the surface of the dishes, achieving a washing effect. The dishes can also be sterilized at high temperature in the boiling water.

[0140] In some embodiments, high-temperature steam converges at the top of the dishwasher, increasing the steam pressure. The steam enters the bubble plate through the return steam hole, where the pressure concentrates again, turning into hot steam bubbles that enter the bottom of the dish. After the bubbles explode, they carry detergent bubbles to complete the vibration washing of the dish and the removal of dirt, such as grease and protein.

[0141] In some embodiments, a portion of the steam pressure enters the heat exchanger through the steam inlet. One side of the heat exchanger is the air side maintained by the fan, and the other side is the steam flow surging out of the dishwasher. When the two meet, they condense, and the heat is absorbed by the water tank. The condensed water will return to the chassis layer through the return hole.

[0142] S206, Control the heating plate to stop working.

[0143] In some embodiments, after the washing time according to the third washing mode has been completed, it indicates that the dish has completed the process of removing dirt, and the heating plate can be controlled to stop working and the water to stop boiling.

[0144] S207: The control motor drives the traction layer to pull the dish out of the water and then back into the water. After repeating the preset number of times according to the third washing mode, it runs to the top rinsing position of the dishwasher.

[0145] The preset number of cycles can be predefined when the dishwasher leaves the factory; for example, the preset number of cycles can be 10.

[0146] In some embodiments, when a dish is immersed in water for bubble washing, the dirt on the surface of the dish has been removed, but it may be re-adsorbed onto the surface of the dish. However, the adhesion of the dirt on the surface of the dish is very weak at this time. The dirt can be completely removed by repeatedly pulling the dish out of the water and then putting it back into the water.

[0147] S208. Control the water pump to operate in the first working state and control the first pipeline valve to open.

[0148] In some embodiments, when it is determined that the dish has reached the top rinsing position of the dishwasher, the water pump can be controlled to operate in a first working state, and the first pipeline valve can be controlled to open, so that the water in the water tank is pumped into the spray hole to rinse the surface of the dish, wash away the water containing detergent on the surface of the dish, and complete the rinsing process of the dish according to the third washing mode.

[0149] In some embodiments, the pressure sensor monitors the pressure value in real time during the rinsing of the dishes. When the pressure value is greater than or equal to the pressure threshold, it controls the second pipeline valve to open and drain the water in the bottom layer to the outside.

[0150] S209. Open the top cover and allow the air to dry.

[0151] In some embodiments, after the dishwashing process is completed according to the third washing mode, the top cover can be popped open to release pressure and allow for air drying. At the same time, the voice prompt device can be controlled to issue a second voice prompt, which is used to remind the user that the dishwashing and disinfection are complete. The content of the second voice prompt can be predefined at the factory of the dishwasher. For example, the content of the second voice prompt can be: "The washing and disinfection of the tableware has been completed. Please use it with confidence." After the second voice prompt is issued, the user can take the cleaned dishwashing plate from the top of the dishwasher.

[0152] In some embodiments, if the user needs to wash other dishes continuously, a continuous washing program is executed. That is, after removing the washed dishes, the top cover is closed, and steps S201 to S203 are repeated. The hot water containing detergent in the base layer can be reused. Figure 16 As shown, the continuous washing program specifically includes the following steps:

[0153] S301, Obtain the turbidity value.

[0154] In some embodiments, since continuous washing allows for the reuse of detergent-containing hot water in the chassis layer, the turbidity value of the detergent-containing hot water in the chassis layer can be obtained before controlling the heating plate to operate, and the turbidity value can be used to determine whether the detergent-containing hot water in the chassis layer meets the conditions for reuse.

[0155] If the turbidity value is greater than or equal to the turbidity threshold, it indicates that the hot water containing detergent in the bottom layer is too dirty and does not meet the conditions for reuse. The water pump can be controlled to operate in the second working state, and the second pipeline valve can be opened to drain the water in the bottom layer to the outside. After the drainage is completed, the second pipeline valve is closed, and the water pump is controlled to operate in the first working state, and the first pipeline valve is opened so that the water in the water tank is pumped into the bottom layer to submerge the dishes. Then, the third washing mode is followed to proceed to the next step.

[0156] If the turbidity value is less than the turbidity threshold, it means that the hot water containing detergent in the chassis layer meets the conditions for reuse, and the next step can be performed according to the third washing mode.

[0157] S302, Obtain the pressure value.

[0158] In some embodiments, the description of step S302 can be referred to the relevant description of step S202 above, and will not be repeated here.

[0159] S303. Determine the type of tableware based on the pressure value.

[0160] In some embodiments, the description of step S303 can refer to the relevant description of step S203 above, and will not be repeated here.

[0161] S304. Start the corresponding washing mode according to the type of tableware.

[0162] In some embodiments, the description of step S304 can refer to the relevant description of step S204 above, and will not be repeated here.

[0163] S305. When the pressure value is greater than or equal to the pressure threshold, control the operation of the corresponding heating point.

[0164] In some embodiments, the description of step S305 can be referred to the relevant description of step S205 above, and will not be repeated here.

[0165] S306, Control the heating plate to stop working.

[0166] In some embodiments, the description of step S306 can refer to the relevant description of step S206 above, and will not be repeated here.

[0167] S307: The control motor drives the traction layer to pull the dish out of the water and then back into the water. After repeating the preset number of times according to the third washing mode, it runs to the top rinsing position of the dishwasher.

[0168] In some embodiments, the description of step S307 can be referred to the relevant description of step S207 above, and will not be repeated here.

[0169] S308. Control the water pump to operate in the first working state and control the first pipeline valve to open.

[0170] In some embodiments, the description of step S308 can refer to the relevant description of step S208 above, and will not be repeated here.

[0171] S309. Open the top cover and allow the air to dry.

[0172] In some embodiments, the description of step S309 can refer to the relevant description of step S209 above, and will not be repeated here.

[0173] In some embodiments, such as Figure 17 As shown, after step S309, the following steps may also be included:

[0174] S310 controls the dishwasher to enter standby mode, while simultaneously controlling the temperature sensor to monitor the water temperature in the chassis layer in real time.

[0175] Understandably, after confirming that the user has closed the top cover, it means that the user has stopped the washing process and can control the dishwasher to enter standby mode. The standby mode is maintained for a second preset time, which can be predefined at the factory, for example, the second preset time can be 600 seconds.

[0176] While the dishwasher is in standby mode, a temperature sensor continuously monitors the water temperature in the tray, tracking changes in temperature. If the water temperature drops below a threshold, it indicates the water is unsuitable for continued washing. This water contains detergent and dirt, and prolonged retention can contaminate the tray. Therefore, to prevent contamination, the water is drained from the tray when the temperature drops below the threshold.

[0177] The temperature threshold can be predefined at the factory when the dishwasher leaves the factory; for example, the temperature threshold can be 30°C.

[0178] If the dishwasher enters standby mode and no drop in water temperature in the tray exceeds the temperature threshold is detected, and the user washes again, a continuous wash mode will be executed.

[0179] S311, Control the water pump to operate in the second working state, and at the same time control the second pipeline valve to open.

[0180] In some embodiments, after a second preset time, or when the temperature of the water in the chassis layer is detected to drop below a temperature threshold, it indicates that the user has finished washing the current time. The water pump can be controlled to run in a second working state, and the second pipeline valve can be controlled to open to discharge the water in the chassis layer to the outside.

[0181] S312, Control the dishwasher to enter the shutdown mode.

[0182] In some embodiments, after the dishwasher has finished draining, it can be controlled to enter the shutdown mode.

[0183] In some embodiments, steps S310 to S312 may also be included after step S209.

[0184] This application also provides an electronic device, such as... Figure 18 As shown, the electronic device 180 includes: one or more processors 1801; one or more memories 1802, wherein the one or more memories 1802 are used to store computer program code, the computer program code including computer instructions; when the one or more processors 1801 execute the computer instructions, the electronic device 180 performs the various steps of the method shown in the above method embodiment.
