[0011] In some possible implementations, the preheating chamber includes a first heating element, and the washing equipment further includes a control mechanism and a first temperature sensor. The first temperature sensor is disposed in the preheating chamber, and the control mechanism is electrically connected to the first heating element and the first temperature sensor respectively. The control mechanism is used to control the switching of the first heating element according to the detection data of the first temperature sensor so that the temperature of the preheating chamber is maintained within a first preset temperature range.

[0012] In some possible implementations, the first connecting valve includes a first valve port, a second valve port, and a third valve port. The first valve port is selectively connected to one of the second valve port and the third valve port. The first valve port is connected to the processing chamber, the second valve port is connected to the input end of the preheating box, and the third valve port is connected to the vacuum pump.

[0013] In some possible implementations, the airflow circulation mechanism further includes a second connecting valve connected between the first connecting valve and the preheating box, the second connecting valve also being in communication with the external environment;

[0014] The input end of the preheating box, the first connecting valve, and one of the external environment are connected to either of the other two via the second connecting valve.

[0015] In some possible implementations, the second connecting valve includes a fourth valve port, a fifth valve port, and a sixth valve port, wherein one of the fourth valve port, the fifth valve port, and the sixth valve port is selectively connected to one of the other two.

[0016] In some possible implementations, the airflow circulation mechanism further includes a second connecting valve connected between the first connecting valve and the clothing processing tub, the second connecting valve also being in communication with the external environment;

[0017] The processing chamber is connected to the first connecting valve and the external environment via the second connecting valve.

[0018] In some possible implementations, the airflow circulation mechanism further includes a dryer connected to the end of the first connecting valve away from the fan and in communication with the processing chamber.

[0019] In some possible implementations, the washing device further includes a second heating element disposed on one side of the laundry tub, the second heating element being used to heat the laundry tub.

[0020] In some possible implementations, the washing device further includes a control mechanism and a second temperature sensor disposed in the processing chamber.

[0025] The beneficial effects of this application are as follows: The washing equipment provided by this application, when drying clothes, can first connect a vacuum pump to the processing chamber. The vacuum pump draws negative pressure into the processing chamber to a preset pressure. Even though the processing chamber is in a negative pressure environment, this lowers the boiling point of water, allowing water to vaporize at a lower ambient temperature, thus achieving low-temperature drying of clothes. This avoids damage to clothes caused by high temperatures and friction, preventing unnecessary losses for the user. Furthermore, an airflow circulation mechanism can be activated to transport heated gas to the processing chamber and discharge the gas from the processing chamber, forming a gas circulation that accelerates the evaporation of moisture from the clothes, increases the drying rate, and shortens the user's waiting time.

[0051] like Figure 1 As shown, an embodiment provides a washing device 1000, which includes a washing process and a drying process. The washing device 1000 may include a clothes handling tub 100, an airflow circulation mechanism 200, and a vacuum pump 310.

[0052] The clothing processing bucket 100 is equipped with a processing chamber 101, which can be used to hold clothing.

[0053] The airflow circulation mechanism 200 is connected to the processing chamber 101. The airflow circulation mechanism 200 can be used to input heated gas into the processing chamber 101 and to discharge the gas in the processing chamber 101 to perform gas circulation.

[0054] The vacuum pump 310 can be connected to the airflow circulation mechanism 200, and the vacuum pump 310 can be connected to the processing chamber 101 through the airflow circulation mechanism 200.

[0055] When using the washing machine 1000 to dry clothes, the washing machine 1000 can execute the drying process. During this process, the vacuum pump 310 can be connected to the processing chamber 101 through the airflow circulation mechanism 200, and the vacuum pump 310 can draw the processing chamber 101 to a preset negative pressure, so that the processing chamber 101 is in a negative pressure environment. This lowers the boiling point of water, allowing water to vaporize into water vapor at a lower ambient temperature, achieving low-temperature drying of clothes, avoiding damage to clothes caused by high temperature and friction, and preventing unnecessary losses to users.

[0056] Additionally, the airflow circulation mechanism 200 can be activated to transport heated gas to the processing chamber 101 and discharge the gas mixed with a large amount of water vapor from the processing chamber 101, thus circulating the gas. This accelerates the evaporation of moisture from the clothes, increases the drying rate, and shortens the user's waiting time.

[0057] like Figure 1As shown, in some embodiments, the washing device 1000 also includes a housing (not shown), and the laundry treatment tub 100, the airflow circulation mechanism 200, the vacuum pump 310, and other structures in the washing device 1000 can be disposed inside the housing or on the surface of the housing, so that the housing can provide corresponding protection for other structural components in the washing device 1000.

[0058] like Figure 1 As shown, in some embodiments, the airflow circulation mechanism 200 includes a first connecting valve 230, a preheating chamber 250, and a fan 220. The first connecting valve 230 includes a first valve port 231, a second valve port 232, and a third valve port 233. The first valve port 231 can be selectively connected to either the second valve port 232 or the third valve port 233. In one embodiment, the first valve port 231 is connected to the processing chamber 101. The second valve port 232 can be connected to the input end of the preheating chamber 250. The third valve port 233 can be connected to the input end of the vacuum pump 310, and the output end of the vacuum pump 310 is connected to the external environment. Accordingly, the vacuum pump 310 can be selectively connected to the processing chamber 101 through the first connecting valve 230.

[0059] In addition, the output end of the preheating box 250 is connected to the input end of the fan 220, and the output end of the fan 220 can be connected to the processing chamber 101. The preheating box 250 can preheat the flowing gas, thereby making the temperature of the gas entering the processing chamber 101 approximately the same as the temperature in the processing chamber 101, reducing the temperature fluctuation of the gas in the processing chamber 101, and ensuring drying efficiency.

[0060] In some embodiments, the first connecting valve 230 may be a three-way solenoid valve.

[0061] In some embodiments, the preheating chamber 250 may include a chamber body 252 and a first heating element 251. The chamber body 252 may be a hollow structure, providing an airflow passage. The first heating element 251 may be disposed inside or on one side of the chamber body 252, and can heat the interior of the chamber body 252 to heat the airflow passing through it.

[0062] In some embodiments, the first heating element 251 may include at least one of the following structures: heating wire, heating rod, heating mesh, ceramic heating tube, etc.

[0063] In some embodiments, the airflow circulation mechanism 200 further includes a second connecting valve 240 and a dryer 210.

[0064] The dryer 210 can be connected between the first connecting valve 230 and the clothing processing tub 100. In this embodiment, the input end of the dryer 210 can be connected to the processing chamber 101, and the output end of the dryer 210 can be connected to the first valve port 231 of the first connecting valve 230. During use, the dryer 210 can dry and filter the flowing gas to remove water vapor from the flowing gas.

[0065] The second connecting valve 240 can be connected between the first connecting valve 230 and the input terminal of the preheating box 250. In some embodiments, the second connecting valve 240 may include a fourth valve port 241, a fifth valve port 242, and a sixth valve port 243, wherein one of the fourth valve port 241, the fifth valve port 242, and the sixth valve port 243 can be selectively connected to the other two. The fourth valve port 241 can be connected to the input terminal of the preheating box 250. The fifth valve port 242 can be connected to the second valve port 232 of the first connecting valve 230. The sixth valve port 243 can communicate with the external environment. In some embodiments, the second connecting valve 240 may be a three-way solenoid valve.

[0066] In some embodiments, the airflow circulation mechanism 200 further includes a first control valve 261 and a second control valve 262. The first control valve 261 can be connected between the output end of the fan 220 and the clothes handling tub 100, and can be used to control the on / off connection between the clothes handling tub 100 and the output end of the fan 220. When the washing equipment 1000 performs the washing process, the first control valve 261 can be kept closed to prevent cleaning fluid and other contaminants from entering the airflow circulation mechanism 200 and to avoid damage to electrical components such as the fan 220. In some embodiments, the first control valve 261 can be a two-way solenoid valve.

[0067] Additionally, the end of the airflow circulation mechanism 200 near the first control valve 261, where it connects to the clothes processing drum 100, can be positioned near the bottom of the clothes processing drum 100. Thus, when the airflow circulation mechanism 200 inputs heated drying gas into the processing chamber 101, the heated drying gas can pass between the clothes to remove water vapor from the surface of the clothes, further improving the drying rate of the clothes.

[0068] In some embodiments, the second control valve 262 may be disposed between the dryer 210 and the laundry treatment tub 100, and may be used to control the on / off connection between the dryer 210 and the laundry treatment tub 100. In some embodiments, the second control valve 262 may also be a two-way solenoid valve.

[0069] In some embodiments, the end of the airflow circulation mechanism 200 near the second control valve 262 is connected to the clothing processing tub 100 near the top of the clothing processing tub 100 so that the gas mixed with a large amount of water vapor in the clothing processing tub 100 can smoothly enter the airflow circulation mechanism 200.

[0070] During the operation of the airflow circulation mechanism 200, the first valve port 231 of the first connecting valve 230 and the second valve port 232 are connected, and the fourth valve port 241 of the second connecting valve 240 and the fifth valve port 242 are connected, forming an internal circulation loop between the airflow circulation mechanism 200 and the processing chamber 101, and starting the fan 220 and the preheating box 250. Under the action of the fan 220, the gas mixed with a large amount of water vapor in the processing chamber 101 can enter the airflow circulation mechanism 200. When the gas passes through the dryer 210, the dryer 210 can filter and dry the gas to remove the water vapor in the airflow. The preheating box 250 can heat the dried gas, and the heated gas can be sent back to the processing chamber 101 under the action of the fan 220 to replace the gas in the processing chamber 101.

[0071] In addition, during the operation of the airflow circulation mechanism 200, the first valve port 231 and the third valve port 233 of the first connecting valve 230 can be connected, and the fourth valve port 241 and the sixth valve port 243 of the second connecting valve 240 can be connected, starting the fan 220 and the preheating box 250. Simultaneously, the vacuum pump 310 can be activated, forming an external circulation loop between the airflow circulation mechanism 200, the processing chamber 101, and the external environment. Gas from the external environment can enter the airflow circulation mechanism 200 through the second connecting valve 240 under the action of the fan 220, and after being heated by the preheating box 250, it enters the processing chamber 101. The gas in the processing chamber 101, mixed with a large amount of water vapor, can be discharged to the external environment through the dryer 210, the first connecting valve 230, and the vacuum pump 310. Thus, the gas in the processing chamber 101 mixed with a large amount of water vapor can be replaced with relatively dry gas, accelerating the evaporation of moisture from the clothing and improving drying efficiency.

[0072] In this embodiment, the dryer 210 is always located upstream of the vacuum pump 310, thereby preventing corrosion damage to the vacuum pump 310 caused by gas mixed with a large amount of water vapor passing through it, thus extending the service life of the vacuum pump 310. Additionally, when the airflow circulation mechanism 200 and the processing chamber 101 form an internal circulation loop, the dryer 210 can also be located upstream of the fan 220 to prevent water vapor from passing through the fan 220 and causing corrosion damage, thus extending the service life of the fan 220 as well.

[0073] In some embodiments, the washing apparatus 1000 further includes a second heating element 320, which may be disposed on one side of the clothes handling tub 100. The second heating element 320 can heat the clothes handling tub 100 when the washing apparatus 1000 performs the drying process to improve the evaporation efficiency of moisture in the clothes.

[0074] In some embodiments, the second heating element 320 may include at least one of the following structures: heating wire, heating plate, heating mesh, or ceramic heating tube.

[0075] In some embodiments, the washing device 1000 further includes a water supply mechanism 410, which can be used to input water into the processing chamber 101 of the clothes processing tub 100. Of course, the water supply mechanism 410 can also be used to input an aqueous solution mixed with laundry detergent into the processing chamber 101.

[0076] In some embodiments, the water supply mechanism 410 may include a third connecting valve 412 and a spray pipe 411. The spray pipe 411 may be installed inside the laundry treatment tub 100, and the spray pipe 411 may have a plurality of spray ports 4111 communicating with the treatment chamber 101.

[0077] The third connecting valve 412 includes a seventh valve port 4121, an eighth valve port 4122, and a ninth valve port 4123. The seventh valve port 4121 can be selectively connected to either the eighth valve port 4122 or the ninth valve port 4123. The seventh valve port 4121 can be used to connect to an external water supply device, such as a tap water pipe or a water tank. The eighth valve port 4122 can be connected to the processing chamber 101 of the laundry processing tub 100. The ninth valve port 4123 can be connected to the spray pipe 411. In some embodiments, the third connecting valve 412 can be a three-way solenoid valve.

[0078] When the washing equipment 1000 performs the washing process, the seventh valve port 4121 and the eighth valve port 4122 of the third connecting valve 412 can be connected, and water supply mechanism 410 injects water into the treatment chamber 101 to wash the clothes.

[0079] In addition, the washing equipment 1000 also includes a spray process. When the washing equipment 1000 performs the spray process, the seventh valve port 4121 and the ninth valve port 4123 of the third connecting valve 412 can be connected, and the water supply mechanism 410 sprays water into the treatment chamber 101 through the spray pipe 411 to rinse the clothes.

[0080] In this embodiment, the connection point between the eighth valve port 4122 and the clothing processing tank 100 can be located near the top of the clothing processing tank 100. The spray pipe 411 can also be located near the top of the clothing processing tank 100.

[0081] In some embodiments, the water supply mechanism 410 may further include a third control valve 413 and a booster pump 414. The output end of the booster pump 414 may be connected to the seventh valve port 4121 of the third connecting valve 412. The third control valve 413 may be connected between the input end of the booster pump 414 and an external water supply device. The booster pump 414 can pressurize the water. The third control valve 413 can switch the water supply mechanism 410 on and off with the external water supply device. In some embodiments, the third control valve 413 may be a two-way solenoid valve.

[0082] In some embodiments, the washing apparatus 1000 further includes a drain mechanism 420 for draining water, such as wastewater, from the processing chamber 101. In this embodiment, the drain mechanism 420 may include a fourth control valve 421 and a drain pump 422. The fourth control valve 421 may be connected between the drain pump 422 and the laundry processing tub 100, and may be used to control the on / off connection between the drain pump 422 and the processing chamber 101. The output end of the drain pump 422 may be connected to an external water collection device, such as a wastewater tank or wastewater pipeline. When it is necessary to drain wastewater from the processing chamber 101, the fourth control valve 421 and the drain pump 422 may be opened to extract the wastewater from the processing chamber 101. In some embodiments, the fourth control valve 421 may be a two-way solenoid valve.

[0083] In some embodiments, the washing apparatus 1000 further includes an ultrasonic mechanism 500. The ultrasonic mechanism 500 may include an electrically connected ultrasonic generator 510 and a plurality of ultrasonic transducers 520. In some embodiments, the plurality of ultrasonic transducers 520 may be distributed on the outer wall of one side of the garment processing tub 100, and may be uniformly or non-uniformly distributed. When the washing apparatus 1000 performs a washing process, the ultrasonic generator 510 can generate a high-frequency oscillation signal and transmit it to the plurality of ultrasonic transducers 520. Upon receiving the oscillation signal, the plurality of ultrasonic transducers 520 can convert it into corresponding mechanical vibrations, which are then transmitted to the cleaning fluid through the garment processing tub 100. The high-frequency sound waves can generate microbubbles in the cleaning fluid, which rapidly expand and burst. During the rapid expansion and bursting of the microbubbles, a large impact force is generated, i.e., a cavitation effect, thereby effectively removing stains from the garments and providing a cleaning function.

[0084] In other embodiments, multiple ultrasonic transducers 520 may also be distributed on multiple side walls, top or bottom of the clothing processing tub 100, and may be uniformly or non-uniformly distributed.

[0085] like Figure 1 and Figure 3 As shown, in some embodiments, the washing device 1000 further includes a control mechanism 360, a first temperature sensor 331, and a second temperature sensor 332. The first temperature sensor 331 is disposed in the preheating chamber 250 and can be used to detect the temperature of the preheating chamber 250 in real time. The second temperature sensor 332 can be disposed in the processing chamber 101 and can be used to detect the temperature in the processing chamber 101 in real time.

[0086] In this embodiment, the control mechanism 360 may integrate a processor 361, a memory 362, and a clock module 364. The control mechanism 360 may be electrically connected to the first temperature sensor 331, the second temperature sensor 332, the first heating element 251, the second heating element 320, and other electrical components in the washing device 1000. During use, the control mechanism 360 may control the switching of the first heating element 251 based on the detection data from the first temperature sensor 331 to maintain the temperature in the preheating chamber 250 within a first preset temperature range. The control mechanism 360 may control the switching of the second heating element 320 based on the detection data from the second temperature sensor 332 to maintain the temperature in the processing chamber 101 within a second preheating temperature range.

[0087] In some embodiments, the washing device 1000 further includes a pressure sensor 340 and a liquid level sensor 350, both of which are electrically connected to the control mechanism 360. The pressure sensor 340 may be disposed in the processing chamber 101 and can be used to detect the real-time pressure in the processing chamber 101. The liquid level sensor 350 may also be disposed in the processing chamber 101 and can be used to detect the liquid level in the processing chamber 101.

[0088] When the washing equipment 1000 performs the washing process, the control mechanism 360 can control the third control valve 413 to open, and the seventh valve port 4121 and the eighth valve port 4122 of the third connecting valve 412 to connect, and the booster pump 414 to start, so as to inject water into the treatment chamber 101. During this process, the water level in the treatment chamber 101 can be detected in real time by the liquid level sensor 350. When the liquid level sensor 350 detects that the water level in the treatment chamber 101 has reached the preset liquid level (i.e., reached the preset volume), the control mechanism 360 can control the booster pump 414 to close, the third control valve 413 to close, and start the ultrasonic mechanism 500 to wash the clothes in the treatment chamber 101. After the control mechanism 360 controls the ultrasonic mechanism 500 to run for a first preset time, the control mechanism 360 can control the ultrasonic mechanism 500 to stop, and control the fourth control valve 421 and the drain pump 422 to open, so as to discharge the sewage in the treatment chamber 101. The first preset duration can be set as needed, for example, the first preset duration can be set to 5 minutes, 8 minutes or 10 minutes or any other duration.

[0089] When the washing equipment 1000 performs the spraying process, the control mechanism 360 can control the third control valve 413 and the booster pump 414 to open, and connect the seventh valve port 4121 and the ninth valve port 4123 of the third connecting valve 412, so that water is sprayed into the treatment chamber 101 through the spray pipe 411 to rinse the clothes in the treatment chamber 101. After the control mechanism 360 controls the water supply mechanism 410 to run for a second preset time, it can control the third control valve 413 and the booster pump 414 to close, so as to complete the rinsing of the clothes. The second preset time can be set as needed, for example, the second preset time can be set to 3 minutes, 5 minutes or 8 minutes or any other arbitrary time. During the spraying process, the fourth control valve 421 and the drain pump 422 of the drain mechanism 420 can always be kept open to discharge the sewage in the treatment chamber 101 in a timely manner.

[0090] When the washing equipment 1000 executes the drying process, the control mechanism 360 can first control the second control valve 262 to open, connecting the first valve port 231 and the third valve port 233 of the first connecting valve 230, and start the vacuum pump 310 to draw the processing chamber 101 into negative pressure to a preset pressure. This creates a negative pressure environment in the processing chamber 101, lowering the boiling point of water, accelerating moisture evaporation, and achieving low-temperature drying of the clothes. Simultaneously, the control mechanism 360 can control the second heating element 320 to start, heating the processing chamber 101 to a second preset temperature to further accelerate moisture evaporation. Subsequently, the control mechanism 360 can control the vacuum pump 310 to shut down, the first control valve 261 to open, the first valve port 231 and the second valve port 232 of the first connecting valve 230 to connect, and the fourth valve port 241 and the fifth valve port 242 of the second connecting valve 240 to connect, thereby turning on the preheating box 250 and the fan 220, and controlling the first heating element 251 to heat the preheating box 250 to the first preheating temperature. Correspondingly, the airflow circulation mechanism 200 can form an internal circulation loop with the processing chamber 101 to continuously replace the gas in the processing chamber 101 with heated dry gas, accelerating the evaporation of moisture from the clothing. The preheating box 250 can also be opened during the process of the vacuum pump 310 drawing negative pressure into the processing chamber 101 for preheating.

[0091] During this drying process, both the first heating element 251 and the second heating element 320 can operate intermittently. The first temperature sensor 331 can monitor the temperature of the preheating chamber 250 in real time. When the temperature of the preheating chamber 250 is outside the first preset temperature range, the control mechanism 360 can control the first heating element 251 to turn on, thereby heating the preheating chamber 250 to the first preset temperature. The first preset temperature can be any temperature value within the first preset temperature range. The second temperature sensor 332 can monitor the temperature in the processing chamber 101 in real time. When the temperature in the processing chamber 101 is outside the second preset temperature range, the control mechanism 360 can control the second heating element 320 to turn on, thereby heating the processing chamber 101 to the second preset temperature. The second preset temperature can be any temperature value within the second preset temperature range.

[0092] During the process of the airflow circulation mechanism 200 replacing the gas in the processing chamber 101, the pressure sensor 340 can detect the pressure in the processing chamber 101 in real time. When the pressure in the processing chamber 101 is not within the preset pressure range, the control mechanism 360 can control the first connecting valve 230 to switch the first valve port 231 and the third valve port 233 to conduct, and turn on the vacuum pump 310 to draw the processing chamber 101 to a negative pressure to the preset pressure. Then, the control mechanism 360 can switch the first connecting valve 230 to switch the first valve port 231 and the second valve port 232 to conduct, and the airflow circulation mechanism 200 will replace the gas in the processing chamber 101. The preset pressure can be any pressure value within the preset pressure range. That is, during the drying process, the airflow circulation mechanism 200 and the vacuum pump 310 can operate alternately.

[0093] In this embodiment, the first preset temperature, the second preset temperature, the first preset temperature range, the second preset temperature range, the preset pressure, and the preset pressure range can all be set as needed, and no specific restrictions are imposed here.

[0094] In some embodiments, during the drying process of the washing equipment 1000, after the vacuum pump 310 draws negative pressure to the processing chamber 101 to a preset pressure, the airflow circulation mechanism 200 can be controlled to start external circulation, and the vacuum pump 310 can be turned on to replace the gas in the processing chamber 101. During this process, the pressure sensor 340 can also detect the pressure in the processing chamber 101 in real time. When the pressure in the processing chamber 101 is not within the preset pressure range, the control mechanism 360 can control the airflow circulation mechanism 200 to stop operating, and the vacuum pump 310 draws negative pressure to the processing chamber 101 to the preset pressure. After that, the external circulation of the airflow circulation mechanism 200 can be restarted. That is, the external circulation of the airflow circulation mechanism 200 can operate intermittently as needed.

[0095] In this embodiment, after the washing equipment 1000 has completed the third preset drying cycle, the control mechanism 360 can control the vacuum pump 310 and the airflow circulation mechanism 200 to stop operating. The pressure sensor 340 can detect the current pressure in the processing chamber 101. When the current pressure in the processing chamber 101 is inconsistent with atmospheric pressure, the control mechanism 360 can control the second control valve 262 to open, connecting the first valve port 231 of the first connecting valve 230 to the second valve port 232, and connecting the fifth valve port 242 of the second connecting valve 240 to the sixth valve port 243. This connects the processing chamber 101 to the external environment, restoring the pressure in the processing chamber 101 to atmospheric pressure, allowing the user to open the clothes processing tub 100 and remove the clothes. In some embodiments, the third preset time can be set as needed, for example, it can be set to 5 minutes, 8 minutes, or 15 minutes, or any other arbitrary duration.

[0096] like Figure 2 As shown, in some embodiments, the second connecting valve 240 may also be disposed between the dryer 210 and the clothing treatment tub 100. The second connecting valve 240 may include a fourth valve port 241, a fifth valve port 242, and a sixth valve port 243, wherein the fourth valve port 241 may be selectively connected to either the fifth valve port 242 or the sixth valve port 243. In the embodiment, the fourth valve port 241 may be connected to the treatment chamber 101. The fifth valve port 242 may be connected to the input end of the dryer 210, and the sixth valve port 243 may be connected to the external environment. During the operation of the airflow circulation mechanism 200, the first valve port 231 of the first connecting valve 230 may be connected to the second valve port 232, and the fourth valve port 241 of the second connecting valve 240 may be connected to the fifth valve port 242, so that the airflow circulation mechanism 200 and the treatment chamber 101 form an internal circulation loop, thereby activating the fan 220 and the preheating box 250. Under the action of the fan 220, the gas mixed with a large amount of water vapor in the processing chamber 101 can enter the airflow circulation mechanism 200. When the gas passes through the dryer 210, the dryer 210 can filter and dry the gas to remove the water vapor in the airflow. The preheating box 250 can heat the dried gas, and then send the gas back to the processing chamber 101 to replace the gas in the processing chamber 101. In addition, after the drying process is completed, the fourth valve port 241 and the sixth valve port 243 of the second connecting valve 240 can be connected to the external environment to depressurize the processing chamber 101 so that the user can easily open the clothes processing drum 100 to take out the clothes.

[0097] like Figure 4 and Figure 5As shown, the embodiment also provides a method for using a washing device, which can be applied to the washing device 1000 provided in the embodiment. In some embodiments, the memory 362 and the processor 361 in the washing device 1000 can be connected via a bus 363. The memory 362 stores program instructions, and the processor 361 can retrieve program instructions from the memory 362 to execute the method for using the washing device 1000 provided in the following embodiment.

[0098] The memory 362 may include high-speed random access memory (RAM), and may also include non-volatile memory, such as at least one disk storage device. The bus 363 can be divided into address bus, data bus, control bus, etc. For ease of representation, Figure 5 The symbol is represented by a single double-headed arrow, but this does not mean that there is only one bus 363 or one type of bus 363.

[0099] Processor 361 may be an integrated circuit chip with signal processing capabilities. In implementation, each step of the washing equipment's usage method can be completed through integrated logic circuits in the hardware or software instructions within processor 361. The aforementioned processor 361 can be a general-purpose processor, including a Central Processing Unit (CPU), a Network Processor (NP), etc.; it can also be a Digital Signal Processor (DSP), an Application Specific Integrated Circuit (ASIC), a Field-Programmable Gate Array (FPGA), or other programmable logic devices, discrete gate or transistor logic devices, or discrete hardware components. The general-purpose processor can be a microprocessor, or processor 361 can be any conventional processor 361.

[0100] like Figure 4 As shown, in some embodiments, the method of using the washing device may include:

[0101] S100, obtain the instructions for the running process.

[0102] In some embodiments, the operating process may include a cleaning process, a spraying process, and a drying process.

[0103] In other embodiments, the operating process may also include any one or two of the following processes: a cleaning process, a spraying process, and a drying process.

[0104] S200, switch to work under the process that matches the instructions.

[0105] In this embodiment, the control mechanism 360 can control the washing equipment 1000 to switch to a process that matches the instructions.

[0106] like Figure 6 and Figure 9 As shown, in some embodiments, when the control mechanism 360 controls the washing device 1000 to perform the washing process, it may include:

[0107] S211, connect the processing chamber 101 to the external water supply device and inject a preset volume of water into the processing chamber 101.

[0108] In some embodiments, the control mechanism 360 can control the third control valve 413 and the booster pump 414 to open, and determine whether the seventh valve port 4121 and the eighth valve port 4122 of the third connecting valve 412 are connected, that is, determine whether the third connecting valve 412 is at the water injection level. When the seventh valve port 4121 and the eighth valve port 4122 are not connected, the control mechanism 360 switches the third connecting valve 4122 to connect the seventh valve port 4121 and the eighth valve port 4122. Then, the water supply mechanism 410 can inject water into the treatment chamber 101. During this process, the level sensor 350 can detect the water level in the treatment chamber 101 in real time to determine whether the water level in the treatment chamber 101 has reached the preset water level. When the level sensor 350 detects that the water level in the treatment chamber 101 has reached the preset water level, the control mechanism 360 can control the third control valve 413 and the booster pump 414 to close.

[0109] S212, start the ultrasonic mechanism 500.

[0110] In this embodiment, the ultrasonic mechanism 500 can be controlled by the control mechanism 360 to generate ultrasonic waves in the processing chamber 101 to clean the clothes in the processing chamber 101.

[0111] S213, when the ultrasonic mechanism 500 has been working for a first preset time, the ultrasonic mechanism 500 is turned off and the water in the treatment chamber 101 is drained.

[0112] In this embodiment, during the operation of the ultrasonic mechanism 500, the clock module 364 in the control mechanism 360 can keep track of the time and determine in real time whether the ultrasonic mechanism 500 has operated for a first preset duration. Once the control mechanism 360 has controlled the ultrasonic mechanism 500 to operate for the first preset duration, it can control the ultrasonic mechanism 500 to stop. The first preset duration can be set as needed. For example, the first preset duration can be set to any other duration such as 5 minutes, 8 minutes, or 10 minutes.

[0113] At the same time, the fourth control valve 421 and the drainage pump 422 of the drainage mechanism 420 can be opened by the control mechanism 360 to discharge the sewage in the treatment chamber 101.

[0114] In some embodiments, during the washing process of the washing equipment 1000, when the liquid level sensor 350 detects that the sewage in the treatment chamber 101 has been emptied, it can send corresponding detection data to the control mechanism 360. The control mechanism 360 can control the washing equipment 1000 to perform the spraying process according to the detection data of the liquid level sensor 350.

[0115] like Figure 7 and Figure 9 As shown, in some embodiments, when the control mechanism 360 controls the washing equipment 1000 to perform the spraying process, it may include:

[0116] S221, connect the spray pipe 411 to the external water supply device and control the spray pipe 411 to spray the treatment chamber 101.

[0117] In this embodiment, the control mechanism 360 can control the seventh valve port 4121 and the ninth valve port 4123 of the third connecting valve 412 to be connected, so that the third connecting valve 412 is switched to the spray position. The control valve 413 is opened to connect the spray pipe 411 to the external water supply device. Simultaneously, the booster pump 414 can be started to spray the treatment chamber 101, rinsing away the wastewater on the surface of the clothing. During this process, the fourth control valve 421 and the drain pump 422 can also be kept open to promptly remove the wastewater from the treatment chamber 101.

[0118] S222, when the spray pipe 411 has been working for the second preset time, disconnect the spray pipe 411 from the external water supply device.

[0119] In this embodiment, the washing equipment 1000 can be controlled by the control mechanism 360 to perform the spraying process for a second preset duration. The second preset duration can be set as needed. For example, the second preset duration can be set to any other duration such as 3 minutes, 5 minutes, or 8 minutes.

[0120] After the washing equipment 1000 has completed the second preset duration of the spraying process, the control mechanism 360 can control the third control valve 413 and the booster pump 414 to close, thereby shutting down the water supply mechanism 410. At the same time, it can control the fourth control valve 421 and the drain pump 422 to close, that is, shut down the drain mechanism 420.

[0121] like Figure 8 As shown, in some embodiments, when the control mechanism 360 controls the washing equipment 1000 to perform the drying process, it may include:

[0122] S231, connect vacuum pump 310 to processing chamber 101, start vacuum pump 310, and draw negative pressure to processing chamber 101 to preset pressure.

[0123] In some embodiments, the second control valve 262 can be controlled to open, so that the first valve port 231 of the first connecting valve 230 is connected to the third valve port 233, and the vacuum pump 310 is turned on to draw the processing chamber 101 to a negative pressure to a preset pressure.

[0124] S232, connect the airflow circulation mechanism 200 to the processing chamber 101 and start the airflow circulation mechanism 200 to replace the gas in the processing chamber 101.

[0125] In some embodiments, the control mechanism 360 can control the opening of the first control valve 261 and the second control valve 262, connect the first valve port 231 and the second valve port 232 of the first connecting valve 230, connect the fourth valve port 241 and the fifth valve port 242 of the second connecting valve 240, and start the fan 220 and the preheating box 250, so that the airflow circulation mechanism 200 and the processing chamber 101 form an internal circulation loop. Under the action of the fan 220, the gas mixed with a large amount of water vapor in the processing chamber 101 can enter the airflow circulation mechanism 200. When the gas passes through the dryer 210, the dryer 210 can filter and dry the gas to remove the water vapor in the airflow. The preheating box 250 can heat the dried gas, and then send the heated dried gas back to the processing chamber 101 to replace the gas in the processing chamber 101, thereby improving the drying efficiency of the clothes.

[0126] In some embodiments, during the operation of the airflow circulation mechanism 200, the first valve port 231 and the third valve port 233 of the first connecting valve 230 can be connected, and the fourth valve port 241 and the sixth valve port 243 of the second connecting valve 240 can be connected. This starts the fan 220 and the preheating box 250, and simultaneously activates the vacuum pump 310, forming an external circulation loop between the airflow circulation mechanism 200, the processing chamber 101, and the external environment. Gas from the external environment can enter the airflow circulation mechanism 200 through the second connecting valve 240 under the action of the fan 220, and after being heated by the preheating box 250, it enters the processing chamber 101. The gas in the processing chamber 101, mixed with a large amount of water vapor, can be discharged to the external environment through the dryer 210, the first connecting valve 230, and the vacuum pump 310. Thus, the gas in the processing chamber 101 mixed with a large amount of water vapor can be replaced with relatively dry gas, accelerating the evaporation of moisture from the clothing and improving drying efficiency.

[0127] S233, obtain the real-time pressure of the processing chamber 101, and determine whether the real-time pressure is within the preset pressure range.

[0128] In some embodiments, the pressure in the processing chamber 101 can be detected in real time by a pressure sensor 340. In an embodiment, if the real-time pressure is not within a preset pressure range, the vacuum pump 310 is controlled to draw the processing chamber 101 to a negative pressure to the preset pressure.

[0129] In this embodiment, when the pressure in the processing chamber 101 is not within the preset pressure range, the control mechanism 360 can control the fan 220 in the airflow circulation mechanism 200 to shut down, and control the first connecting valve 230 to switch the first valve port 231 and the third valve port 233 to conduct, so that the vacuum pump 310 is connected to the processing chamber 101 and the vacuum pump 310 is started to draw the processing chamber 101 to a negative pressure to the preset pressure. Then, the first connecting valve 230 is controlled to switch the first valve port 231 and the second valve port 232 to conduct, and the airflow circulation mechanism 200 replaces the gas in the processing chamber 101. The preset pressure can be any pressure value within the preset pressure range.

[0130] It is understandable that when the real-time pressure in the processing chamber 101 is within the preset pressure range, the gas in the processing chamber 101 can be continuously replaced by the airflow circulation mechanism 200.

[0131] Throughout the drying process, the negative pressure in the processing chamber 101 and the gas in the processing chamber 101 can be alternated.

[0132] S234, after the washing equipment has completed the third preset time of the drying process, the airflow circulation mechanism 200 and the vacuum pump 310 are turned off.

[0133] In this embodiment, the control mechanism 360 can control the washing equipment 1000 to execute the drying process for a third preset duration to dry the clothes. The third preset duration can be set as needed, for example, it can be set to any other duration such as 5 minutes, 8 minutes, or 15 minutes.

[0134] After the drying process has been completed for the third preset time, the control mechanism 360 can control the vacuum pump 310 and the electrical components in the airflow circulation mechanism 200 to shut down.

[0135] like Figure 8 As shown, in some embodiments, the drying process further includes:

[0136] S235, obtain the current pressure of the processing chamber 101, and when the current pressure is inconsistent with the atmospheric pressure, adjust the pressure of the processing chamber 101 to be consistent with the atmospheric pressure.

[0137] In this embodiment, at the end of the drying process, the pressure sensor 340 can detect the current pressure in the processing chamber 101 and send the detection data to the control mechanism 360. When the current pressure in the processing chamber 101 is inconsistent with atmospheric pressure, the control mechanism 360 can control the processing chamber 101 to depressurize, so that the pressure in the processing chamber 101 is consistent with atmospheric pressure, so that the user can open the clothes processing tub 100 to take out the clothes. Specifically, the second control valve 262 can be controlled to open, the first valve port 231 of the first connecting valve 230 is connected to the second valve port 232, and the fifth valve port 242 of the second connecting valve 240 is connected to the sixth valve port 243, so that the processing chamber 101 is connected to the external environment to depressurize the processing chamber 101.

[0138] like Figure 2 and Figure 9 As shown, in some other embodiments, the second connecting valve 240 is connected between the processing chamber 101 and the first valve port 231 of the first connecting valve 230. When the washing equipment 1000 performs the drying process, step S320 may also include:

[0139] The system determines whether the fourth valve port 241 of the second connecting valve 240 is connected to the fifth valve port 242, i.e., whether the second connecting valve 240 is in the dryer position. When the fourth valve port 241 and the fifth valve port 242 are not connected, the system can control the second connecting valve 240 to switch to the connection between the fourth valve port 241 and the fifth valve port 242. Similarly, the system determines whether the first valve port 231 of the first connecting valve 230 is connected to the third valve port 233, i.e., whether the first connecting valve 230 is in the vacuum position. When the first valve port 231 and the third valve port 233 are not connected, the system can control the first connecting valve 230 to switch to the connection between the first valve port 231 and the third valve port 233. This allows the vacuum pump 310 to be connected to the processing chamber 101.

[0140] Then, the vacuum pump 310 can be started to draw negative pressure into the processing chamber 101. During this process, the pressure sensor 340 can detect the pressure in the processing chamber 101 in real time and determine whether the pressure in the processing chamber 101 has reached the preset pressure. When the pressure in the processing chamber 101 has not reached the preset pressure, the vacuum pump 310 can continue to work.

[0141] When the pressure sensor 340 detects that the pressure in the processing chamber 101 has reached the preset pressure, the control mechanism 360 can control the first connecting valve 230 to switch the first valve port 231 and the second valve port 232 to conduct, that is, switch the first connecting valve 230 to the fan position and shut down the vacuum pump 310. Subsequently, the fan 220 can be started, and the preheating box 250 can also be turned on. Of course, the preheating box 250 can also be turned on in advance. Under the action of the fan 220, the gas mixed with a large amount of water vapor in the processing chamber 101 can enter the airflow circulation mechanism 200. When the gas passes through the dryer 210, the dryer 210 can filter and dry the gas to remove the water vapor in the airflow. The preheating box 250 can heat the dried gas, and then send the heated dried gas back to the processing chamber 101 to replace the gas in the processing chamber 101.

[0142] During the operation of the airflow circulation mechanism 200, the pressure in the processing chamber 101 can be detected in real time by the pressure sensor 340. When the pressure in the processing chamber 101 is detected to be outside the preset pressure range, the control mechanism 360 can control the first connecting valve 230 to switch the first valve port 231 to the third valve port 233, shut down the fan 220, and start the vacuum pump 310 to draw the processing chamber 101 to a negative pressure to the preset pressure. Afterwards, the first connecting valve 230 can be controlled to switch the first valve port 231 to the second valve port 232, start the fan 220, shut down the vacuum pump 310, and run the airflow circulation mechanism 200 to replace the gas in the processing chamber 101.

[0143] After the washing equipment 1000 has completed the third preset drying cycle, the control mechanism 360 can control the fan 220 to shut down and the preheating box 250 to shut down, causing the first connecting valve 230 to switch between the first valve port 231 and the third valve port 233, and shutting down the vacuum pump 310. Simultaneously, it can control the second connecting valve 240 to switch between the fourth valve port 241 and the sixth valve port 243, that is, to switch the second connecting valve 240 to the atmospheric pressure position, connecting the processing chamber 101 to the external environment to depressurize the processing chamber 101. When the pressure in the processing chamber 101 matches atmospheric pressure, the drying process ends, and the user can open the clothes processing tub 100 to remove the clothes.

[0144] like Figure 10 As shown, the embodiment also provides a washing device 2000, including a negative pressure module 2100, an airflow circulation module 2200, a pressure detection module 2300, and a control module 2400.

[0145] The vacuum module 2100 is used to create a negative pressure in the processing chamber 101 during the drying process of the washing equipment 1000. The airflow circulation module 2200 is used to deliver heated gas to the processing chamber 101 and vent the gas in the processing chamber 101 for gas circulation during the drying process of the washing equipment 1000. The pressure detection module 2300 is used to detect the pressure in the processing chamber 101 in real time. The control module 2400 is used to control the vacuum pump 310 and the airflow circulation mechanism 200 to operate alternately according to the pressure changes in the processing chamber 101.

[0146] 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 361, the computer-executable instructions cause the processor 361 to implement the above-described washing device 1000 usage method.
