Description

Technical Field

[0001] This application relates to the technical field of washing machines, and more particularly to a washing device. Background Technology

[0002] Washing machines free up consumers' hands, providing users with a more convenient and efficient way to do laundry.

[0003] After washing clothes, washing machines typically dry and spin-dry them. However, in order to increase the drying speed, traditional washing machines usually heat the clothes to a high temperature during the drying and spin-drying process to accelerate the evaporation of moisture. During this process, some clothes may be damaged due to excessive heat, resulting in losses for the user. Utility Model Content

[0004] This application provides a washing device for achieving low-temperature drying, thereby reducing damage to clothing.

[0005] This application provides a washing device, which includes a washing process and a drying process, comprising:

[0006] Washing tub, equipped with a washing chamber;

[0007] An ultrasonic mechanism is disposed on one side of the washing tub, and the ultrasonic mechanism is used to generate ultrasonic waves in the washing chamber.

[0008] A vacuuming mechanism is connected to the washing chamber and is used to evacuate the washing chamber.

[0009] A circulation mechanism, connected to the washing chamber, is used to input heated gas into the washing chamber and discharge the gas in the washing chamber for gas circulation.

[0010] In some possible implementations, the vacuuming mechanism includes a vacuum pump and a first control valve connected in series, with one end of the first control valve remote from the vacuum pump connected to the washing chamber.

[0011] In some possible implementations, the vacuuming mechanism further includes a first filter connected between the first control valve and the vacuum pump.

[0012] In some possible implementations, the circulation mechanism includes a preheating box and a fan, the output end of the preheating box being connected to the input end of the fan, and the output end of the fan being connected to the washing chamber;

[0013] The input end of the preheating box is connected to the washing chamber and / or the external atmosphere.

[0014] In some possible implementations, the circulation mechanism further includes a second filter, the output of which is connected to the input of the preheating chamber, and the input of which is connected to the washing chamber and / or the external atmosphere.

[0015] In some possible implementations, the circulation mechanism further includes a first conveying branch and a second conveying branch, the output ends of the first conveying branch and the second conveying branch being connected to the input end of the preheating box;

[0016] The input end of the first conveying branch is connected to the washing chamber, and a second control valve is configured on the first conveying branch;

[0017] The input end of the second conveying branch is connected to the external atmosphere, and a third control valve is installed on the second conveying branch.

[0018] In some possible implementations, the washing device further includes a control unit electrically connected to the second control valve and the third control valve, respectively, and the control unit is used to control the on / off state of the second control valve and / or the third control valve.

[0019] In some possible implementations, a fourth control valve is also provided between the output end of the fan and the washing chamber.

[0020] In some possible implementations, the washing equipment further includes a heating element disposed on one side of the washing tub, the heating element being used to heat the washing chamber at least during the drying process.

[0021] In some possible implementations, the ultrasonic mechanism includes an ultrasonic generator and a plurality of ultrasonic transducers connected together, the plurality of ultrasonic transducers being distributed on at least one side of the washing tub.

[0022] The beneficial effects of this application are as follows: The washing equipment provided by this application, during the drying process, can use a vacuum mechanism to evacuate the washing chamber to a preset pressure. Even though the washing chamber is in a negative pressure environment, this lowers the boiling point of water, allowing the moisture in the clothes to vaporize at a lower temperature. While ensuring the rate of moisture evaporation, this achieves low-temperature drying of clothes, avoiding damage caused by high temperatures. Furthermore, the ventilation mechanism can be activated as needed to replace the gas mixed with a large amount of water vapor in the washing chamber with dry gas, accelerating the vaporization of moisture in the clothes, further improving drying efficiency, reducing user waiting time, and thus improving the user experience.

[0046] like Figure 1 As shown, the embodiment provides a washing device 1000 that can be used to provide washing and drying functions.

[0047] In some embodiments, the washing equipment 1000 may include a washing process and a drying process, and the user may select the washing equipment 1000 to operate in the washing process and / or the drying process as needed.

[0048] like Figure 1 As shown, in some embodiments, the washing device 1000 includes a washing tub 100, an ultrasonic mechanism 200, a vacuum mechanism 300, and a circulation mechanism 400.

[0049] The washing tub 100 is equipped with a washing chamber 101 for holding clothes to be washed. An ultrasonic device 200 is disposed on one side of the washing tub 100. In this embodiment, the ultrasonic device 200 is used to generate ultrasonic waves in the washing chamber 101 when the washing equipment 1000 is in the washing process.

[0050] Both the vacuuming mechanism 300 and the circulation mechanism 400 are connected to the washing chamber 101. The vacuuming mechanism 300 is used to create a vacuum in the washing chamber 101 when the washing equipment 1000 is in the drying process. This lowers the boiling point of water, accelerates the vaporization of moisture in the clothes within the washing chamber 101, and improves the drying efficiency. The circulation mechanism 400 is used to introduce heated gas into the washing chamber 101 and circulate the gas in the washing chamber 101 during the drying process.

[0051] like Figure 1 and Figure 2 As shown, it can be understood that the washing device 1000 may further include a control unit 610, a water inlet pipe 511, a water inlet control valve 512, a drain pipe 521, and a drain control valve 522. The control unit 610 can be electrically connected to other electrical components in the washing device 1000, and can uniformly control the operation of each electrical component in the washing device 1000. In some embodiments, the control unit 610 may integrate a processor 611, a memory 612, and a clock module 614, etc.

[0052] One end of the water injection pipe 511 can be connected to the washing chamber 101, and the other end of the water injection pipe 511 can be connected to a water supply device, such as a tap water pipe. The water injection control valve 512 can be located at the input end, output end, or in the middle of the water injection pipe 511, and can be used to control whether the water injection pipe 511 injects cleaning fluid into the washing chamber 101. The cleaning fluid can be tap water or a mixed solution containing detergent such as laundry liquid or washing powder. In some embodiments, the water injection control valve 512 can be a solenoid valve.

[0053] One end of the drain pipe 521 can be connected to the bottom of the washing chamber 101, and the other end of the drain pipe 521 can be used to connect to a sewage pipe or sewage tank. The drain control valve 522 can be set at the inlet end, outlet end, or in the middle of the drain pipe 521, and the drain control valve 522 can be used to control whether to discharge sewage from the washing chamber 101. In some embodiments, the drain control valve 522 can also be a solenoid valve.

[0054] During the use of the washing equipment 1000, the user can place the clothes to be washed into the washing chamber 101. When the washing equipment 1000 executes the washing process, the control unit 610 can first control the water injection control valve 512 to open, so as to inject a preset volume of cleaning liquid into the washing chamber 101. After the cleaning liquid has been injected, the control unit 610 can control the water injection control valve 512 to close. Subsequently, the control unit 610 can control the ultrasonic mechanism 200 to start, so as to generate ultrasonic waves in the washing chamber 101.

[0055] During the ultrasonic cleaning process, the ultrasonic waves generated by the ultrasonic unit 200 are transmitted to the cleaning fluid in the washing chamber 101. These high-frequency sound waves generate tiny bubbles in the cleaning fluid, which rapidly expand and burst. The rapid expansion and bursting of these tiny bubbles generates a significant impact force, known as cavitation, which effectively removes stains from clothing.

[0056] After the ultrasonic cleaning device 1000 controls the ultrasonic mechanism 200 to work for a first preset time, the ultrasonic mechanism 200 can be stopped, thus completing the ultrasonic cleaning step. The drain control valve 522 on the drain pipe 521 is then opened to drain the wastewater from the washing chamber 101. In this embodiment, the first preset time can be set as needed, for example, it can be set to 5 minutes, 8 minutes, 10 minutes, or any other arbitrary duration.

[0057] In some embodiments, when the washing equipment 1000 performs the washing process, a rinsing step may be included after the ultrasonic cleaning step is completed. Specifically, after the ultrasonic cleaning step is completed, the control unit 610 can control the water injection control valve 512 to open to inject tap water into the washing chamber 101. Subsequently, the ultrasonic mechanism 200 can be turned on again to rinse the underwear in the washing chamber 101. After the ultrasonic mechanism 200 has been working for a third preset time, the ultrasonic mechanism 200 can be controlled to stop working, and the drain control valve 522 can be opened to drain the wastewater in the washing chamber 101. The rinsing step may be performed once, twice, or any other number of times as needed. In the embodiments, the third preset time may also be set as needed, for example, the third preset time may be set to 5 minutes, 8 minutes, 10 minutes, or any other time.

[0058] When the washing machine 1000 executes the drying process, the control unit 610 can control the vacuum mechanism 300 to evacuate the washing chamber 101 to a preset pressure. Even though the washing chamber 101 is in a negative pressure environment, this lowers the boiling point of water, allowing the moisture in the clothes to vaporize at a lower temperature. This ensures drying efficiency while achieving low-temperature drying of the clothes, avoiding damage caused by high temperatures and preventing unnecessary losses for the user. Additionally, the circulation mechanism 400 can be activated as needed to introduce heated gas into the washing chamber 101 and expel the gas mixed with a large amount of water vapor from the washing chamber 101 to form a gas circulation, accelerating the vaporization of moisture in the clothes, improving drying efficiency, reducing user waiting time, and thus improving the user experience.

[0059] In some embodiments, the washing device 1000 may also include a housing (not shown), the washing tub 100 and other structures in the washing device 1000 may be disposed inside the housing and on the surface of the housing, and the housing may provide corresponding protection for the other structures in the washing device 1000.

[0060] like Figure 1 As shown, in some embodiments, the vacuum pumping mechanism 300 may include a connected vacuum pump 310 and a first control valve 320. The end of the first control valve 320 away from the vacuum pump 310 may be connected to the washing chamber 101. The end of the vacuum pump 310 away from the first control valve 320 may be connected to the outside atmosphere. In some embodiments, the first control valve 320 may be a solenoid valve.

[0061] In other embodiments, the first control valve 320 may also be a manual valve or the like.

[0062] When it is necessary to evacuate the washing chamber 101, the vacuum pump 310 and the first control valve 320 can be turned on. The vacuum pump 310 can gradually extract the gas in the washing chamber 101 to create a negative pressure environment inside the washing chamber 101. The first control valve 320 can be used to control the connection and disconnection between the branch of the vacuum pump 310 and the washing chamber 101.

[0063] In some embodiments, the vacuuming mechanism 300 further includes a first filter 330. The first filter 330 may be disposed between the vacuum pump 310 and the first control valve 320. In this embodiment, the first filter 330 can filter out moisture in the flowing gas, preventing airflow containing excessive moisture from passing through the vacuum pump 310 and causing corrosion damage to the vacuum pump 310, thereby extending the service life of the vacuum pump 310 and the washing equipment 1000.

[0064] like Figure 1 As shown, in some embodiments, the ultrasonic mechanism 200 may include an ultrasonic generator 210 and a plurality of ultrasonic transducers 220 connected to each other. The ultrasonic transducers 220 are disposed on the side of the washing tub 100 opposite to the washing cavity 101, i.e., on the outer side of the washing tub 100. In some embodiments, the plurality of ultrasonic transducers 220 may be distributed on one side of the periphery of the washing tub 100, and may be uniformly or non-uniformly distributed.

[0065] In other embodiments, a plurality of ultrasonic transducers 220 may be distributed around the periphery and / or bottom and / or top of the washing tub 100, and may be uniformly or non-uniformly distributed.

[0066] During operation of the ultrasonic mechanism 200, the ultrasonic generator 210 can generate high-frequency oscillation signals and transmit them to multiple ultrasonic transducers 220. Upon receiving the oscillation signals, the multiple ultrasonic transducers 220 convert them into corresponding mechanical vibrations, which are then transmitted to the cleaning fluid through the washing tub 100 to provide a cleaning function.

[0067] In some embodiments, the washing apparatus 1000 further includes a heating element 700. The heating element 700 may be disposed on one side of the washing tub 100. The heating element 700 can heat the washing chamber 101 during the washing process to enhance the activity of active enzymes in the detergent in the washing liquid, resulting in cleaner clothes and improved washing performance. Additionally, the heating element 700 can also heat the washing chamber 101 during the drying process to accelerate the evaporation of moisture from the clothes and improve drying efficiency.

[0068] In the embodiments, the heating element 700 may be an electric heating wire, an electric heating plate, an electric heating rod, an electric heating tube, or an electric heating mesh, etc.

[0069] In other embodiments, the heating element 700 may also operate only during the drying process.

[0070] like Figure 1 As shown, in some embodiments, the circulation mechanism 400 may include a second filter 460, a fan 420, and a fourth control valve 450. The input end of the second filter 460 may be connected to the washing chamber 101 and / or the external atmosphere. The output end of the second filter 460 may be connected to the input end of the fan 420. The second filter 460 can dry and filter the flowing gas to reduce the moisture content in the gas. The output end of the fan 420 may be connected to the washing chamber 101. The fan 420 can serve as a power source in the circulation mechanism 400, driving the gas flow within the circulation mechanism 400. Furthermore, the fourth control valve 450 is connected between the output end of the fan 420 and the washing chamber 101, and the fourth control valve 450 can be used to control the on / off connection between the washing chamber 101 and the output end of the fan 420. In some embodiments, the fourth control valve 450 may be a solenoid valve.

[0071] In other embodiments, the fourth control valve 450 may also be a manual valve or similar structure.

[0072] During operation, the circulation mechanism 400 can obtain gas from the outside atmosphere or the washing chamber 101, and the second filter 460 dries and filters the flowing gas to remove moisture. The dried gas can then enter the washing chamber 101 through the fan 420 and the fourth control valve 450 to replace the gas mixed with a large amount of water vapor in the washing chamber 101.

[0073] In some embodiments, the connection point between the circulation mechanism 400 and the washing tub 100 may be located near the bottom end of the washing tub 100. Thus, when the circulation mechanism 400 introduces drying gas into the washing chamber 101, the drying gas can pass between the clothes to remove water vapor from the surface of the clothes, further accelerating the drying rate.

[0074] In some embodiments, the circulation mechanism 400 may include a first conveying branch 430 and a second conveying branch 440. The input end of the first conveying branch 430 may be connected to the washing chamber 101. The input end of the second conveying branch 440 may be connected to the outside atmosphere. In addition, the output ends of both the first conveying branch 430 and the second conveying branch 440 are connected to the input end of the second filter 460.

[0075] In some embodiments, the connection point between the first conveying branch 430 and the washing tub 100 may be located near the top end of the washing tub 100 so that the gas mixed with a large amount of water vapor in the washing tub 100 can smoothly enter the first conveying branch 430.

[0076] In some embodiments, a second control valve 431 is further provided on the first conveying branch 430, which can be used to control the on / off state of the first conveying branch 430. A third control valve 441 is further provided on the second conveying branch 440, which can be used to control the on / off state of the second conveying branch 440. In some embodiments, both the second control valve 431 and the third control valve 441 can be solenoid valves.

[0077] In other embodiments, the second control valve 431 and the third control valve 441 may also be configured as manual valves or similar structures.

[0078] In some embodiments, the circulation mechanism 400 further includes a preheating chamber 410. The preheating chamber 410 may be disposed between the fan 420 and the second filter 460. The preheating chamber 410 can heat the flowing dry gas, so that the temperature of the dry gas entering the washing chamber 101 is approximately the same as the temperature inside the washing chamber 101, reducing temperature fluctuations inside the washing chamber 101, ensuring efficient evaporation of moisture from the clothes, and improving drying efficiency.

[0079] During the operation of the circulation mechanism 400, the fourth control valve 450 can be in the open state, and the first conveying branch 430 and the second conveying branch 440 can be connected selectively or simultaneously.

[0080] When the first conveying branch 430 is connected and the second conveying branch 440 is closed, the gas mixed with a large amount of water vapor in the washing chamber 101 can enter the first conveying branch 430 under the action of the fan 420, and then pass through the second filter 460, the preheating box 410 and the fan 420 in sequence. The second filter 460 absorbs the water vapor in the flowing gas to dry it. The preheating box 410 heats the flowing gas to ensure that the temperature of the gas entering the washing chamber 101 is basically consistent with the temperature inside the washing chamber 101. This increases the evaporation rate of moisture in the clothes inside the washing chamber 101, accelerating the drying efficiency. During this process, the pressure inside the washing chamber 101 remains basically constant, i.e., the washing chamber 101 is essentially maintained in a negative pressure environment.

[0081] When the second conveying branch 440 is connected and the first conveying branch 430 is closed, air from the outside atmosphere can enter the second conveying branch 440 under the action of the fan 420, and then enter the circulation mechanism 400. The air entering the circulation mechanism 400 passes sequentially through the second filter 460, the preheating box 410, and the fan 420 before entering the washing chamber 101. The second filter 460 absorbs water vapor in the flowing air, thus drying it. The preheating box 410 heats the flowing air to ensure that the temperature of the air entering the washing chamber 101 is essentially consistent with the temperature inside the washing chamber 101, reducing temperature fluctuations within the washing chamber 101 and ensuring the evaporation rate of moisture from the clothes, thereby ensuring a faster drying rate. After gas is supplied to the washing chamber 101 for a period of time, the pressure inside the washing chamber 101 gradually returns to atmospheric pressure due to the continuous input of outside air. Subsequently, the control unit 610 can control the vacuum mechanism 300 to start, so as to draw negative pressure back into the washing chamber 101 and expel the gas from the washing chamber 101. During the drying process, the control unit 610 can control the vacuum mechanism 300 and the circulation mechanism 400 to operate alternately, so as to deliver the heated and dried gas to the washing chamber 101 and expel the gas in the washing chamber 101 for gas circulation, thereby accelerating the evaporation of moisture from the clothes in the washing chamber 101 and improving the drying efficiency.

[0082] When both the first conveying branch 430 and the second conveying branch 440 are connected, the gas mixed with a large amount of water vapor in the washing chamber 101 and the gas from the outside atmosphere can be simultaneously input into the circulation mechanism 400. The gas entering the circulation mechanism 400 passes sequentially through the second filter 460, the preheating box 410, and the fan 420 before entering the washing chamber 101. The second filter 460 absorbs the water vapor in the flowing gas, thus drying it. The preheating box 410 heats the flowing gas to ensure that the temperature of the gas entering the washing chamber 101 is essentially consistent with the temperature inside the washing chamber 101, preventing large temperature fluctuations and ensuring the evaporation rate of moisture from the clothes, thereby ensuring the drying rate. After the circulation mechanism 400 has been running for a period of time, the pressure inside the washing chamber 101 will return to atmospheric pressure. Subsequently, the control unit 610 can control the vacuum mechanism 300 to activate, thereby drawing negative pressure back into the washing chamber 101 and expelling the gas from it. During the drying process, the control unit 610 can control the vacuum mechanism 300 and the circulation mechanism 400 to operate alternately, which can deliver the heated and dried gas to the washing chamber 101 and discharge the gas in the washing chamber 101 for gas circulation, accelerate the evaporation of moisture from the clothes in the washing chamber 101, efficiently remove moisture from the clothes, and improve drying efficiency.

[0083] In some embodiments, the washing equipment 1000 may control the vacuum mechanism 300 and the circulation mechanism 400 to stop after running for a second preset time during the drying process, thereby completing the drying process and drying the clothes. In the embodiments, the second preset time can also be set as needed, for example, the second preset time can be set to 10 minutes, 12 minutes, 15 minutes or other arbitrary durations.

[0084] like Figure 1 and Figure 2 As shown, in some embodiments, the washing device 1000 may further include a water level sensor 650, a first temperature sensor 620, a second temperature sensor 630, and a pressure sensor 640. The water level sensor 650 may be disposed in the washing chamber 101 and can be used to detect the water level in the washing chamber 101. The first temperature sensor 620 is disposed in the washing chamber 101 and can be used to detect the temperature in the washing chamber 101 in real time. The second temperature sensor 630 may be disposed in the preheating chamber 410 and can be used to detect the temperature in the preheating chamber 410 in real time. Additionally, the pressure sensor 640 may be disposed in the washing chamber 101 and can be used to detect the pressure in the washing chamber 101 in real time.

[0085] In some embodiments, during the drying process, after the control unit 610 stops the vacuum mechanism 300 and the circulation mechanism 400 after running for a second preset time, the pressure sensor 640 can detect the pressure inside the washing chamber 101. When the pressure inside the washing chamber 101 is inconsistent with atmospheric pressure, for example, higher or lower than atmospheric pressure, the pressure inside the washing chamber 101 can be adjusted to restore the pressure inside the washing chamber 101 to atmospheric pressure, so that the user can open the door of the washing tub 100 to take out the clothes.

[0086] In some embodiments, the washing apparatus 1000 may also include a humidity sensor (not shown) for real-time detection of the humidity within the washing chamber 101. During the drying process performed by the washing apparatus 1000, the humidity sensor can detect the humidity within the washing chamber 101 in real time. When the real-time humidity within the washing chamber 101 is less than or equal to a preset humidity, the control unit 610 can control the vacuum mechanism 300 and the circulation mechanism 400 to stop operating, thereby achieving the drying of the clothes. The preset humidity can be set as needed.

[0087] In some embodiments, the washing device 1000 may further include an operation panel (not shown) for user input of commands, including commands for mode selection, water level selection, etc. In these embodiments, the operation panel may include at least one of a touchscreen, a button panel, and a knob.

[0088] like Figures 1 to 4As shown, the embodiment also provides a method for using a washing device (hereinafter referred to as the usage method), which can be applied to the washing device 1000 provided in the embodiment. In some embodiments, the memory 612 and the processor 611 in the washing device 1000 can be connected via a bus 613.

[0091] like Figures 1 to 3 As shown, in some embodiments, the method of use may include:

[0092] S100, start washing equipment 1000.

[0093] In this embodiment, the user can start the washing device 1000 via the operation panel, which means the washing device 1000 is turned on.

[0094] S200, the instruction to obtain the operating mode.

[0095] Users can input commands for the operating mode through the control panel to select the operating mode of the washing machine 1000.

[0096] S300 switches to a working mode that matches the instructions.

[0097] In some embodiments, the operating modes of the washing equipment 1000 may include a washing mode, a drying mode, and a wash-dry mode. The washing mode may include a washing process. The drying mode may include a drying process. The wash-dry mode may include both a washing process and a drying process.

[0098] In other embodiments, the operating mode of the washing equipment 1000 may also include any one or two of the washing mode, drying mode, and wash-dry mode.

[0099] In this embodiment, when the washing device 1000 is in washing mode, the control unit 610 can control the washing device 1000 to perform the washing process. When the washing device 1000 is in drying mode, the control unit 610 can control the washing device 1000 to perform the drying process. When the washing device 1000 is in wash-dry mode, the control unit 610 can control the washing device 1000 to perform the washing process and the drying process sequentially.

[0100] like Figure 1 , Figure 2 and Figure 5 As shown, in some embodiments, the washing process may include:

[0101] S311, inject a preset volume of cleaning fluid into the washing chamber 101.

[0102] In this embodiment, the control unit 610 can control the water injection control valve 512 to open, thereby injecting cleaning fluid into the washing chamber 101. During this process, the water level sensor 650 can detect the water level of the cleaning fluid in the washing chamber 101 in real time. When the water level sensor 650 detects that the water level in the washing chamber 101 has reached the preset water level (i.e., the cleaning fluid in the washing chamber 101 has reached the preset volume), the control unit 610 can control the water injection control valve 512 to close, thereby completing the injection of the cleaning fluid.

[0103] S312 controls the ultrasonic mechanism 200 to operate for the first preset duration.

[0104] After the cleaning solution is fully injected, the control unit 610 can control the ultrasonic mechanism 200 to start and operate for a first preset time to achieve ultrasonic cleaning of the clothes in the washing chamber 101, dissolving the stains on the clothes in the cleaning solution. The first preset time can be set as needed.

[0105] In some embodiments, the washing process further includes:

[0106] S313, drain the sewage from the washing chamber 101.

[0107] In this embodiment, after the ultrasonic mechanism 200 stops operating for a first preset time, the control unit 610 can control the drain control valve 522 to open, thereby draining the sewage from the washing chamber 101. During this process, the water level sensor 650 can detect the water level in the washing chamber 101 in real time. When the water level sensor 650 detects that the water level in the washing chamber 101 is zero, it indicates that the sewage in the washing chamber 101 has been drained, and the control unit 610 can control the drain control valve 522 to close.

[0108] In some embodiments, the washing process further includes: activating the heating element 700 to heat the temperature of the washing chamber 101 to a second preset temperature. That is, heating the cleaning liquid in the washing chamber 101 to the second preset temperature to enhance the activity of active enzymes in the detergent, improve the cleaning effect, and make the clothes cleaner. In the embodiments, this step can be performed simultaneously with step S312, or this step can be performed before step S312.

[0109] In this embodiment, when the temperature in the washing chamber 101 reaches the second preset temperature, the control unit 610 can control the heating element 700 to stop working. During the washing process, the first temperature sensor 620 can also detect the temperature in the washing chamber 101 in real time. When the temperature in the washing chamber 101 is lower than the second preset temperature by a second preset temperature difference value, the control unit 610 can control the heating element 700 to restart, so as to heat the washing chamber 101 to the second preset temperature. In this embodiment, the second preset temperature can be set according to the needs of the detergent in the cleaning solution. For example, the second preset temperature can be set to 40°C or other arbitrary temperature values. The second preset temperature difference value can also be set as needed.

[0110] like Figure 1 , Figure 2 and Figure 6 As shown, in some embodiments, the drying process may include:

[0111] S321, activate the vacuum pumping mechanism 300 to evacuate the washing chamber 101 to the preset pressure.

[0112] In this embodiment, the control unit 610 can control the first control valve 320 to open and the vacuum pump 310 to start, thereby evacuating the washing chamber 101 to a preset pressure. During this process, the pressure sensor 640 can detect the pressure in the washing chamber 101 in real time. When the pressure sensor 640 detects that the pressure in the washing chamber 101 reaches the preset pressure, the control unit 610 can control the vacuum pump 310 to stop working and control the first control valve 320 to close. Furthermore, throughout the entire drying process, the pressure sensor 640 can detect the pressure in the washing chamber 101 in real time to obtain the real-time pressure within the washing chamber 101. When the pressure sensor 640 detects that the real-time pressure in the washing chamber 101 is greater than the preset pressure and the preset pressure difference, the control unit 610 can control the vacuuming mechanism 300 to restart, thereby evacuating the washing chamber 101 to the preset pressure. In this embodiment, both the preset pressure and the preset pressure difference can be set as needed.

[0113] S322, start the preheating box 410 to heat the temperature of the preheating box 410 to the first preset temperature.

[0114] In this embodiment, the preheating chamber 410 can be started by the control unit 610, causing its temperature to continuously rise to a first preset temperature. During this process, the second temperature sensor 630 can monitor the temperature of the preheating chamber 410 in real time. When the second temperature sensor 630 detects that the temperature of the preheating chamber 410 has reached the first preset temperature, the control unit 610 can control the preheating chamber 410 to stop heating. The first preset temperature can be set as needed. Throughout the drying process, the second temperature sensor 630 can monitor the temperature in the preheating chamber 410 in real time to obtain its real-time temperature. When the second temperature sensor 630 detects that the real-time temperature in the preheating chamber 410 is lower than the first preset temperature difference, the control unit 610 can control the preheating chamber 410 to restart, so that its temperature rises to the first preset temperature. The first preset temperature and the first preset temperature difference can be set as needed.

[0115] In some embodiments, the drying process further includes:

[0116] S323, start the heating element 700 to heat the temperature of the washing chamber 101 to the third preset temperature.

[0117] In this embodiment, the control unit 610 can control the heating element 700 to start, thereby heating the washing chamber 101. During this process, the first temperature sensor 620 can detect the temperature in the washing chamber 101 in real time. When the temperature in the washing chamber 101 reaches a third preset temperature, the control unit 610 can control the heating element 700 to stop working. Throughout the entire drying process, the first temperature sensor 620 can also detect the temperature inside the washing chamber 101 in real time to obtain the real-time temperature. When the real-time temperature inside the washing chamber 101 is lower than the third preset temperature difference, the control unit 610 can control the heating element 700 to restart, thereby heating the washing chamber 101 to the third preset temperature. In this embodiment, the third preset temperature and the third preset temperature difference can be set as needed, or can be selected and set by the user.

[0118] In this embodiment, the execution order of steps S321, S322 and S323 is not specifically limited. For example, steps S321, S322 and S323 can be executed sequentially or simultaneously.

[0119] In some embodiments, the drying process further includes:

[0120] S324, start the fan 420, open the fourth control valve 450, and control the second control valve 431 and / or the third control valve 441 to open.

[0121] In this embodiment, after the washing chamber 101 has been maintained in a negative pressure environment for a fourth preset period of time, the gas in the washing chamber 101 becomes rich in water vapor. The control unit 610 can then control the fourth control valve 450 to open and the fan 420 to start, and control the second control valve 431 and / or the third control valve 441 to open. The second control valve 431 and the third control valve 441 can be selectively opened according to a preset setting.

[0122] When the control unit 610 controls the second control valve 431 to open and the third control valve 441 to close, i.e., when the first conveying branch 430 is connected and the second conveying branch 440 is closed, the gas mixed with a large amount of water vapor in the washing chamber 101 can enter the first conveying branch 430 under the action of the fan 420, and pass through the second filter 460, the preheating box 410 and the fan 420 in sequence. The second filter 460 absorbs the water vapor in the flowing gas to dry it. The preheating box 410 heats the flowing gas to ensure that the temperature of the gas entering the washing chamber 101 is basically consistent with the temperature inside the washing chamber 101. This increases the evaporation rate of moisture in the clothes inside the washing chamber 101, accelerating the drying efficiency. During this process, the pressure inside the washing chamber 101 remains basically constant, i.e., the washing chamber 101 is essentially maintained in a negative pressure environment.

[0123] When the control unit 610 controls the third control valve 441 to open and the second control valve 431 to close, that is, when the second conveying branch 440 is connected and the first conveying branch 430 is closed, gas from the outside atmosphere can enter the second conveying branch 440 under the action of the fan 420, and then enter the circulation mechanism 400. The gas entering the circulation mechanism 400 passes sequentially through the second filter 460, the preheating box 410, and the fan 420 before entering the washing chamber 101. The second filter 460 absorbs water vapor in the flowing gas to dry it. The preheating box 410 heats the flowing gas to ensure that the temperature of the gas entering the washing chamber 101 is basically consistent with the temperature inside the washing chamber 101, reducing temperature fluctuations within the washing chamber 101, ensuring the evaporation rate of moisture in the clothes, and ensuring the drying rate. After the gas in the washing chamber 101 has been replaced for a period of time, the pressure in the washing chamber 101 will gradually return to atmospheric pressure as the outside atmosphere is continuously introduced into the washing chamber 101. Subsequently, the control unit 610 can control the vacuuming mechanism 300 to start, so as to vacuum the washing chamber 101 again, and can control the vacuuming mechanism 300 and the circulation mechanism 400 to run alternately, so as to accelerate the evaporation of moisture from the clothes in the washing chamber 101 and improve the drying efficiency.

[0124] When the control unit 610 controls both the third control valve 441 and the second control valve 431 to open, that is, when both the first conveying branch 430 and the second conveying branch 440 are connected, the gas mixed with a large amount of water vapor in the washing chamber 101 and the gas from the outside atmosphere can be simultaneously input into the circulation mechanism 400. The gas entering the circulation mechanism 400 passes sequentially through the second filter 460, the preheating box 410, and the fan 420 before entering the washing chamber 101. The second filter 460 absorbs the water vapor in the flowing gas to dry it. The preheating box 410 heats the flowing gas to ensure that the temperature of the gas entering the washing chamber 101 is essentially consistent with the temperature inside the washing chamber 101, preventing large temperature fluctuations and ensuring the evaporation rate of moisture from the clothes, thereby ensuring the drying rate. After the gas in the washing chamber 101 has been replaced for a period of time, the pressure in the washing chamber 101 will increase or even return to atmospheric pressure. Subsequently, the control unit 610 can control the vacuuming mechanism 300 to restart, so as to vacuum the washing chamber 101 again. It can also control the vacuuming mechanism 300 and the circulation mechanism 400 to run alternately to accelerate the evaporation of moisture from the clothes in the washing chamber 101, efficiently remove moisture from the clothes, and improve drying efficiency.

[0125] In some embodiments, the drying process further includes:

[0126] S325 controls the washing equipment 1000 to operate for the second preset time of the drying process.

[0127] In this embodiment, the clock module in the control unit 610 can monitor the execution of the drying process in real time. When the clock module detects that the drying process has run for a second preset time, it can control the vacuuming mechanism 300 and the circulation mechanism 400 to stop operating. Of course, it can also control the heating element 700 to stop working.

[0128] In other embodiments, the humidity in the washing chamber 101 can be detected in real time by a humidity sensor. When the real-time humidity in the washing chamber 101 is lower than the preset humidity, the control unit 610 can control the vacuum mechanism 300 and the circulation mechanism 400 to stop operating.

[0129] S326, Obtain the real-time pressure in the washing chamber 101, and when the real-time pressure in the washing chamber 101 is inconsistent with the atmospheric pressure, adjust the pressure in the washing chamber 101 to be consistent with the atmospheric pressure.

[0130] In this embodiment, the pressure sensor 640 can detect the pressure in the washing chamber 101. When the pressure in the washing chamber 101 is inconsistent with atmospheric pressure, the pressure in the washing chamber 101 can be adjusted to restore the pressure in the washing chamber 101 to atmospheric pressure, so that the user can open the door of the washing tub 100 and take out the clothes in the washing chamber 101. Exemplarily, the control unit 610 can control the second control valve 431 and the third control valve 441 to open simultaneously, so that the washing chamber 101 is connected to the outside atmosphere, thereby realizing the adjustment of the pressure in the washing chamber 101.

[0131] In some embodiments, when the washing equipment 1000 is in the washing and drying mode, after the control unit 610 learns from the detection signal of the water level sensor 650 that the sewage in the washing chamber 101 has been drained, it can control the washing equipment 1000 to directly execute the drying process.

[0132] like Figure 7 As shown, the embodiment also provides a washing device 2000, including an instruction acquisition module 2100 and a control module 2200.

[0133] The instruction acquisition module 2100 can be used to acquire instructions for the operating mode. In this embodiment, the user can input instructions for the operating mode through the operation panel to select the operating mode of the washing equipment 1000.

[0134] The control module 2200 can be used to control the washing device 1000 to switch to an operating mode that matches the command. The operating mode of the washing device 1000 may include at least one of a washing mode, a drying mode, and a wash-dry mode. Exemplarily, in some embodiments, the operating mode of the washing device 1000 may include a washing mode, a drying mode, and a wash-dry mode.

[0135] This application also provides a computer-readable storage medium storing computer-executable instructions. When the computer-executable instructions are called and executed by the processor 611, the computer-executable instructions cause the processor 611 to implement the above-described washing device usage method.
